Description

  The present invention relates to a storage provided with a drawer capable of storing an object to be stored.

  In the kitchen, many storage spaces are provided to store cooking utensils, cooking materials, tableware, and the like. For this reason, a drawer or a hinged door is usually provided under the top plate (worktop in the system kitchen). In recent years, research on kitchen usage has been progressed, and it has been attempted to improve usability by devising the size of the drawer and the shape of the partition, assuming a certain amount of objects to be stored in the drawer. As such an example, a stove cabinet having a stove is provided with a large drawer or a swing door for putting a pan or the like, and a base cabinet having a cooking space is provided with many shallow drawers for putting tableware or cooking utensils.

  By the way, in order to provide a storage space under the top plate, the drawer is inevitably at a low position. For this reason, the user puts in and out the stored items by bending down or crouching down. This may be a burden on some users, such as when standing in the kitchen for a long time, or when the body is not free due to aging.

  Therefore, conventionally, a device for facilitating loading / unloading of a stored object has been studied with respect to a drawer at a low position. Patent Document 1 discloses a configuration of a cabinet provided with a drawer lifting mechanism. Patent Document 1 is characterized in that the drawer and the cabinet body are prevented from colliding by raising and lowering only when the drawer is completely pulled out.

JP 2007-215678 A

  In the configuration disclosed in the above-mentioned Patent Document 1, it is considered that it is easy to take out the stored object because the position of the drawer becomes high, but it is configured to raise the entire drawer while rotating. However, the drawer is composed of a wooden or metal front plate, a bottom plate, a side plate, and the like, and has a considerable weight even if nothing is accommodated. In addition, when various objects are stored in the drawer, the labor required to rotate the objects may be much greater than bending it. It may be possible to assist the lifting force with an air cylinder or an electric motor, but the mechanism may become complicated, leading to an increase in kitchen production costs, or the mechanism may overwhelm the storage space and cause a fall. is there.

  On the other hand, among the items to be stored in the drawer, the items that are frequently used during cooking work are limited. That is, it is not necessary to lift all the drawers to a high position.

  Further, in the configuration disclosed in Patent Document 1, the drawer cannot be raised unless the drawer is completely pulled out because of fear of collision with the cabinet. Then, the user working in the kitchen has to go down one step and pull out the drawer greatly, and if it overlaps frequently, there is a risk that it will be annoying.

  Furthermore, if the operation of pulling out and the operation of raising are separate actions, two actions are necessary even if the operation is necessarily accommodated. For this reason, the user is troublesome in the operation itself, and there is a possibility that the precious functions may not be used.

  Therefore, the present invention provides a storage that can improve the usability of a drawer at a low position by raising a sufficient amount of objects to be stored with a simple mechanism and simple and easy operation. It is intended to provide.

In order to solve the above-described problems, a typical configuration of a storage according to the present invention is a storage that can slidably store a drawer that can store an object to be stored, and is disposed in the drawer, A mounting member capable of mounting an object to be stored; a support member that supports the mounting member; a column member that guides the support member in the vertical direction; and a spring that biases the support member upward with respect to the column member; , comprising a support member, a slidable slide member in the vertical direction by the pillar members, the arm connected toward the rear side from the sliding member, a pulley provided on the inner side of the arm, the The storage is further provided with a rail that is arranged on a wall plate in the storage and guides the pulley, and the rail is formed by a groove formed in a plate-like base, and from the back side of the storage to the front side It has the inclination part which goes up toward the.

  According to the said structure, the mounting member arrange | positioned inside a drawer can be raised / lowered with the simple mechanism using a rail, a pulley, and a spring, and the to-be-contained object accommodated in the mounting member is raised and taken out. It can be made easier. At this time, since the placing member moves up and down with the operation of taking out and taking out the drawer, the operation is simple and easy. Moreover, the convenience of the drawer | drawer in a low position can be improved by raising to sufficient height required in order to take out a to-be-contained object without bending. In particular, since the rail is formed by a groove, the upper and lower sides of the pulley can be simultaneously regulated. Thus, the rail can function both when the pulley (and thus the support member) is pushed up and down as the drawer is pulled in and out.

  The groove constituting the rail is preferably bottomed. Thereby, the wall surface of a storage and a pulley do not rub. Accordingly, it is possible to prevent wear of the storage wall surface (in many cases, wood) and reduce sliding friction by the bottom surface of the groove of the rail (in many cases, resin) to ensure smooth operation.

  Said rail is good to be provided with the rib for anti-wheel-removal which stands up toward the edge which opposes at either one of the groove | channel lower side or upper side edge.

  With this configuration, it is possible to reliably prevent the pulley from being removed from the rail (dropping off), and to smoothly operate the drawer. Also, by providing ribs on either one side, that is, only on the lower side or only on the upper side, it is possible to prevent the pulley from getting caught by the upper and lower ribs and becoming difficult to move.

  The above arm is provided with a plurality of pulleys, and a plurality of rails are preferably formed on the plate-like base. As a result, a plurality of pulleys can run on each of the plurality of rails, and stability during arm operation can be improved as compared with the case where only one pulley is used.

  The plurality of pulleys include an upper pulley disposed on the upper side and the back side of the rail, and a lower pulley disposed on the lower side and the front side of the rail, and the upper pulley travels on the plurality of rails. The upper rail and the lower rail on which the lower pulley travels are formed. The interval between the upper rail and the lower rail of the inclined portion is preferably substantially equal to the horizontal interval between the upper pulley and the lower pulley.

  By arranging the pulleys as in the above configuration, the two pulleys can be simultaneously guided up and down, and the distance between the two pulleys can be provided, so that the arms can be kept horizontal. Thus, the arm can be moved up and down while maintaining a substantially horizontal posture, and the mounting member can be moved up and down in a substantially vertical direction. Further, among the plurality of rails, when the upper pulley runs on the upper rail and the lower pulley runs on the lower rail, play of these pulleys is moderately suppressed. Thereby, it is possible to reduce the rattling of the arm and prevent the arm from rotating (moving) in an unintended direction.

  It is preferable that a concave portion that curves downward is formed at the front end of the rail. With this configuration, when the entire drawer is taken out from the storage case, the pulley (particularly the upper pulley) passes through the recess, so that contact between the pulley and the rail can be avoided, and damage to these can be prevented.

  Said rail is good to be arrange | positioned by contact | abutting the rear end in the said storage with the rear end of a plate-shaped base. Thereby, when attaching a rail to the wall surface of a storage, it can contact | abut to a back surface and can position, and a rail can be attached easily and correctly.

  According to the present invention, with a simple mechanism, the operation is simple and easy, and the storage can improve the usability of the drawer at a low position by raising a sufficient storage object as necessary. Can be provided.

  FIG. 1 is a diagram illustrating a kitchen including a storage according to the present embodiment. The kitchen 100 is a so-called system kitchen provided with a plurality of storage cabinets (cabinets) under one top plate 110 (work top). The top plate 110 is made of synthetic resin (artificial marble), stainless steel, or the like, and covers the entire top surface of the kitchen 100.

  The top plate 110 is provided with a stove 112 attached in a built-in manner, a cooking space 114, and a sink 116 integrally formed with the top plate 110. A cooking space 114 located between the sink 116 and the stove 112 is a flat table surface and is mainly used for cooking.

  Under the top plate 110, the storage cabinet includes a stove cabinet 120 in which the main body of the stove 112 is installed, a base cabinet 130 corresponding to the cooking space 114, and a sink cabinet 140 in which the sink 116 is installed. Each storage box functions as a storage space, and an empty space in the storage box also contains wiring to the stove 112, a water supply / drain pipe to the sink 116 and the faucet, and the like. As described above, a plurality of storages corresponding to the respective components such as the sink 116 and the stove 112 on the top plate 110 are provided under the top plate 110 with the same height and depth.

  Each storage is slidably provided with drawers of various sizes in order to store the items to be stored. For example, the stove cabinet 120 includes a grill 112a of the stove 112 and an operation panel 112b at the top, and a spice box 122, which is a small drawer for storing small items such as seasonings, is disposed on the side. A wide wide drawer 124 is disposed at the center of the stove cabinet 120, that is, under the grill 112a, and can accommodate a relatively large cooking utensil such as a pan or bowl. Further, a floor container 126 which is a drawer type foot storage is disposed near the floor below the stove cabinet 120.

  Similarly, the base cabinet 130 is provided with a plurality of relatively small drawers 132, 134 and a floor container 136. The sink cabinet 140 is provided with a floor container 146 and a drawer 144 having a high front plate extending from the floor container 146 to the top plate 110.

  Next, the storage which is a feature of this embodiment will be described. Of the stove cabinet 120, the base cabinet 130, and the sink cabinet 140, the base cabinet 130 will be described as an example.

  FIG. 2 is an exploded perspective view of the base cabinet 130, and FIG. 3 is a view showing a state where the mounting member 150 and the support member 160 are attached to the drawer 134. As described above, the upper drawer 132, the middle drawer 134, and the lower floor container 136 are slidably accommodated in the base cabinet 130. In addition, since the rail mechanism for taking in / out the drawers 132, 134, and 136 itself may be a general one, the description thereof is omitted.

  In the middle drawer 134, a placement member 150 on which an object to be stored can be further placed is arranged, and the placement member 150 can be moved up and down by a lifting mechanism described later. FIG. 4 is a diagram illustrating the mounting member 150. In the present embodiment, the mounting member 150 has a box shape with the top surface opened, and has a so-called pocket shape.

  As shown in FIG. 4, the mounting member 150 includes a partition 154 and a partition groove 156. Thereby, the partition 154 can be inserted into the partition groove 156, and the storage space in the mounting member 150 can be divided. Therefore, the objects to be stored placed in the placement member 150 can be organized and organized. In particular, by providing a plurality of partitions 154 and partition grooves 156, the space in the mounting member 150 can be divided into a plurality of portions, and the size of the divided spaces can be adjusted to a desired size, improving convenience. To do.

  In the present embodiment, the number of partitions 154 is one and the number of partition grooves 156 is three. However, the present invention is not limited to this. The number of partitions 154 and partition grooves 156 may be one or more, and preferably the number of partition grooves 156 is larger than the number of partitions 154.

  Further, a hook-shaped fitting portion 152 is formed on one side of the upper edge of the mounting member 150, and the fitting portion 152 is suspended from a beam 166 of a support member 160 described later (see FIG. 3). The mounting member 150 is configured to be detachable from the beam 166 (supporting member 160). Thereby, since the mounting member 150 can be exchanged, the shape, volume, number of pieces to be attached, and the like can be selected. Moreover, since the mounting member 150 can be removed, cleaning becomes easy.

  The elevating mechanism includes a support member 160 (see FIG. 5) and a column member 180 provided in the drawer 134, and a rail member 200 provided on the wall plate 130a in the base cabinet 130. Each element of the support member 160 and the column member 180 and the rail member 200 are configured symmetrically in the left-right direction of the drawer 134, and two are arranged on each of the left and right sides (mirror symmetry) except for the beam 166. Hereinafter, members constituting the elevating mechanism will be described in detail, and then a link mechanism for assisting the elevating mechanism and elevating of the mounting member 150 using the elevating mechanism will be described in detail.

  The support member 160 is a member that supports the placement member 150. FIG. 5 is a diagram showing details of the support member 160. FIG. 5A is a perspective view of the support member 160 viewed from the outside of the drawer 134, and FIG. 5B is a perspective view of the support member 160 viewed from the inside of the drawer 134. As shown in FIG. 5, the support member 160 includes a sliding member 162, a connecting member 164, a beam 166, an arm 168, and a plurality of pulleys (an upper pulley 170 and a lower pulley 172).

  The sliding member 162 is arranged on both sides of the drawer 134 and is configured to be slidable in the vertical direction by a pillar member 180 fixedly installed on the drawer 134. A connecting member 164 that can connect the beam 166 and the arm 168 is attached to the sliding member 162. As a result, the entire support member 160 and the mounting member 150 can slide in the vertical direction with respect to the column member 180.

  The sliding member 162 includes an upper and lower roller 162a. Thereby, the up-and-down roller 162a is inserted in the up-and-down rail 180b of the column member 180 mentioned later, and moves in this up-and-down rail 180b. Accordingly, the sliding member 162 can move up and down on the column member 180 without dropping from the column member 180. In this embodiment, the sliding member 162 includes two upper and lower rollers 162a. However, the present invention is not limited to this, and the sliding member 162 may include one or more upper and lower rollers 162a.

  Further, the sliding member 162 has a shaft portion 162b. Thereby, the sliding member 162 (supporting member 160) can pivotally support a first link member 182 described later. In this embodiment, the sliding member 162 includes two shaft portions 162b. However, the present invention is not limited to this, and the sliding member 162 may include one or more shaft portions 162b.

  The connecting member 164 has a beam connecting portion 164a for connecting the beam 166 and an arm connecting portion 164b for connecting an arm 168 described later. As a result, the connecting members 164 are respectively attached to the two sliding members 162 provided on both sides of the drawer 134, and the ends of the beams 166 are connected to the beam connecting portions 164a of the two connecting members 164. The member 162 and the beam 166 can be connected to form a frame that accommodates the placement member 150. Then, by connecting the arm 168 to the arm connecting portion 164 b of the connecting member 164, the sliding member 162 and the arm 168 are connected, and the sliding member 162 can be interlocked with the movement of the arm 168.

  The beam 166 supports the mounting member 150 when the fitting portion 152 of the mounting member 150 is suspended. The connecting member 164 is connected to the end of the beam 166, so that the beam 166 operates integrally with the sliding member 162 to which the connecting member 164 is attached.

  In the present embodiment, the sliding member 162, the connecting member 164, and the beam 166 are all separated. However, the present invention is not limited to this, and they may be integrally molded.

  The arm 168 is connected (connected) to the sliding member 162 via the connecting member 164 so as to extend toward the back side of the drawer 134. In this embodiment, the arm 168 includes an arm portion 168a and an L-shaped portion 168b, and the L-shaped portion 168b is fixed to the distal end of the arm portion 168a. The rear end of the L-shaped portion 168b is bent upward in an L-shape. The upper pulley 170 is at the leading end (high position), and the lower pulley 172 is near the connection portion with the arm portion 168a (low position). Is installed. That is, a plurality of pulleys (upper pulley 170 and lower pulley 172) are provided on the back side of the arm 168.

  The upper pulley 170 and the lower pulley 172 move on the upper rail 210 and the lower rail 220, which will be described later, with the movement of the drawer 134. The upper pulley 170 and the lower pulley 172 are arranged so that the arm 168 assumes a substantially horizontal posture when they are mounted on the rail member 200.

  Specifically, the upper pulley 170 is disposed at a position where the upper rail 210 of the rail member 200 to be described later can be moved and at a position on the back side of the drawer 134, and the lower pulley 172 can move the lower rail 220 of the rail member 200. It is arranged at a position that is at the right side and from the front side of the drawer 134. Thereby, when the drawer 134 is pulled out from the base cabinet 130, the upper pulley 170 and the lower pulley 172 move along the shapes of the upper rail 210 and the lower rail 220, and the arm 168 is interlocked with the movement of the drawer 134. It becomes possible.

  In the embodiment, the arm 168 includes the arm portion 168a and the L-shaped portion 168b. However, the present invention is not limited to this, and these may be formed integrally.

  The column member 180 is a member that guides the support member 160 (sliding member 162) in the vertical direction. FIG. 6 is a member for explaining details of the column member 180. FIG. 6A is a view showing a state where the cover 198 is attached to the column member 180, and FIG. 6B is a view showing a state where the cover 198 is removed from the column member 180. As shown in FIG. 6, the column member 180 includes a fixed portion 180 a, upper and lower rails 180 b, and each member constituting a link mechanism.

  The fixing portion 180 a is a member for fixing and installing the column member 180 on the rear surface of the front plate 134 a of the drawer 134. Thus, when the drawer 134 is pulled out or pushed out, the column member 180 can move in the same direction as the drawer 134.

  The upper and lower rails 180b are rails that guide the sliding member 162 (supporting member 160) up and down, and the cross section thereof is C-shaped. Accordingly, by inserting the upper and lower rollers 162a of the above-described sliding member 162 into the upper and lower rails 180b, the upper and lower rollers 162a can move in the upper and lower rails 180b, so that the column member 180 is moved to the sliding member 162 (support member 160). ) Can be guided up and down.

  Further, as shown in FIG. 6B, the column member 180 includes a cover 198 that covers the link mechanism and the like. Thereby, it is possible to protect members constituting a link mechanism such as a spring 186 described later from colliding with an object to be stored stored in the drawer 134 and to prevent breakage of these members. The cover 198 includes an observation window 198a for observing the position of the upper and lower blocks 190 described later. Thereby, the position of the upper and lower blocks 190 moved by the adjusting screw 192 described later and the degree of relaxation of the spring 186 can be visually confirmed.

  Further, as described above, the column member 180 includes each member constituting the link mechanism. In the link mechanism, a plurality of link members are pivotally supported to each other, and the column member 180 and the support member 160 are connected to assist the lifting and lowering of the mounting member 150 in the lifting mechanism. The link mechanism includes a first link member 182, a second link member 184 having a crank shape, a spring 186, a regulating member 188, an upper and lower block 190, and an adjustment screw 192 (see FIG. 6). .

  The first link member 182 is a plate-like member made of metal. One end of the first link member 182 is pivotally fixed to the shaft portion 162b of the sliding member 162 so that the first link member 182 is pivotally supported downward from the sliding member 162 (support member 160). And the other end of the 1st link member 182 is connected with the 2nd link member 184 so that rotation is possible.

  The second link member 184 (crank) is a plate-shaped member made of metal, and one end of the second link member 184 (crank) is rotatably connected to the first link member 182. And the other end of the 2nd link member 184 is pivotally supported by the pillar member 180 so that rotation is possible.

  In this embodiment, the spring 186 is a tension spring, one end of which is a connecting portion (link mechanism) between the first link member 182 and the second link member 184 and the other end is a spring engaging portion of an upper and lower block 190 described later. 190a is connected. Thereby, the sliding member 162 (support member 160) is urged upward with respect to the column member 180.

  The regulating member 188 is a member that plays the role of stopping rotation. As a result, the first link member 182 and the second link member 184 are rotated as the mounting member 150 is lowered, that is, the support member 160 is lowered, and the first link member is reached when the support member 160 reaches the bottom dead center. 182 and the second link member 184 abut against the regulating member 188. Therefore, further (excessive) rotation of the first link member 182 and the second link member 184 after reaching the bottom dead center of the support member 160 can be prevented.

  In the present embodiment, the regulating member 188 includes a cushioning material 188a. Thereby, the impact when the first link member 182 and the second link member 184 come into contact with the regulating member 188 can be reduced, damage to the first link member 182 and the second link member 184 is prevented, and These collision sounds can be reduced. As the buffer material 188a, a material that absorbs impact, such as foamed resin, air packing, rubber, or the like, can be preferably used.

  FIG. 7 is a view for explaining the movement of the link mechanism by the spring 186. FIG. 7A shows a state where the drawer 134 is housed in the base cabinet 130 and the support member 160 is not raised. FIG. 7B shows a state in which the drawer 134 is pulled out partway from the base cabinet 130 and the support member 160 is raised partway. FIG. 7C shows a state where the drawer 134 is completely pulled out from the base cabinet 130 and the support member 160 is raised to the top. FIG. 7D shows a state where the regulating member 188 is not provided. In addition, in order to make an understanding easy, illustration is abbreviate | omitted about the member which is not used for the following description.

  In FIG. 7A, the spring 186 is in a state of being fully extended by being pulled by the connecting portion of the first link member 182 and the second link member 184. When the drawer 134 is pulled out from the base cabinet 130 (not shown) from this state, the support member 160 starts to rise in the direction of the arrow in conjunction with the movement of the drawer 134 by an elevating mechanism described later. Then, the first link member 182 and the second link member 184 begin to rotate in the direction of the arrow, and accordingly, the spring 186 contracts in the direction of the arrow, and the support member 160 (and the mounting member 150 supported by the same). ) Is urged upward to a state shown in FIG.

  When the drawer 134 is further pulled out (not shown), the support member 160 is further raised in the direction of the arrow from the state shown in FIG. 7B, and the first link member 182 and the second link member 184 are in the direction of the arrow. And the spring 186 further contracts in the direction of the arrow. Thereby, the support member 160 (and the mounting member 150 supported by the support member 160) is further biased upward. As a result, as shown in FIG. 7C, the support member 160 rises to the top.

  By providing the link mechanism described above, the support member 160 is biased upward by the force of the spring 186. Thereby, the operation of pulling out the drawer 134 is assisted, and the force for raising the placement member 150 can be reduced. In particular, the spring 186 is connected to the link mechanism (the connecting portion between the first link member 182 and the second link member 184) to bias the support member 160 upward, so that the force of the spring 186 is applied to the support member 160. Rather than transmitting directly to the device, it is possible to obtain an appropriate biasing force according to the position of the support member 160, and it is possible to realize comfortable usability.

  In the present embodiment, the distance L between the two rotation axes of the second link member 184 is the lower side of the first link member 182 when the support member 160 is at the bottom dead center (see FIG. 7A). The height H from the rotation axis to the rotation axis of the second link member 184 and the column member 180 is substantially equal. Thereby, when the support member 160 reaches the bottom dead center, the rotation axes of the first link member 182 and the second link member 184 are below the circle that is the locus of the rotation axis. Thereby, when the support member 160 is at the bottom dead center of the vertical movement, the second link member 184 is in a posture substantially parallel to the direction of the urging force by the spring 186.

  More specifically, since the urging force of the spring 186 acts in the tangential direction of the circle that is the locus on the rotation axis, the crank of the link mechanism acts as the tension of the spring 186 when the support member 160 reaches the bottom dead center. When the support member 160 is used, the force (component force) for urging upward becomes extremely small. Therefore, when the support member 160 approaches the bottom dead center, the upward biasing force of the spring 186 is rapidly weakened. Thereby, the pushing force when the drawer 134 is pushed into the base cabinet 130 (storage) becomes easier, and the usability can be improved as compared with the case where the spring 186 is simply connected directly.

  Further, according to the above configuration, when the drawer 134 is housed, the force with which the pulleys 170 and 172 are pressed against the rail member 200 by the biasing force of the spring 186 can be reduced. More specifically, when the spring 186 is directly connected to the support member 160, the upper pulley 170 and the lower pulley 172 enter the back side horizontal portions 210a and 220a on the back side from the inclined portions 210b and 220b of the rail member 200 described later. Therefore, the upper pulley 170 and the lower pulley 172 are urged to the rail member 200 with the maximum force. For this reason, when the upper pulley 170, the lower pulley, and the rail member 200 are molded of resin, there is a possibility that these contact surfaces may be deformed or scraped due to increased friction. However, since the link mechanism receives the urging force of the spring 186 by configuring as described above, the urging force of the pulleys (the upper pulley 170 and the lower pulley 172) against the rail member 200 is reduced, and these deformations and Wear can be prevented.

  In addition, since the restriction member 188 is provided as in the present embodiment, when the support member 160 reaches the bottom dead center, the first link member 182 and the second link member 184 abut against the restriction member 188, so that their operations ( The rotation stops (see FIG. 7A). If the restriction member 188 is not provided, the first link member 182 and the second link member 184 rotate as the support member 160 descends, and when the support member 160 reaches bottom dead center, the first link member The rotational axes of 182 and the second link member 184 pass through the lower end of the circle that is the locus of the rotational axis, and the state shown in FIG.

  In this case, since the link mechanism is pulled up by the spring 186, the rotary shaft is held where the lower end of the circle has passed, and the first link member 182 and the second link member are pulled when the drawer 134 is pulled out again. As a result, the support member 160 (the mounting member 150) does not rise. However, by providing the restricting member 188, further (excessive) rotation of the first link member 182 and the second link member 184 after reaching the bottom dead center of the support member 160 is prevented, and the situation described above is avoided. It becomes possible.

  The upper and lower blocks 190 move up and down in the column member 180 when an adjustment screw 192 described later is operated. FIG. 8 is a diagram for explaining the details of the upper and lower blocks 190 and the adjusting screw 192. As shown in FIG. 8A, the upper and lower block 190 has a spring engaging portion 190a, and the end of the spring 186 is engaged with the spring engaging portion 190a as shown in FIG. 8B. As a result, as will be described later, the adjustment screw 192 is operated to move the upper and lower blocks 190 and the degree of relaxation of the spring 186 can be adjusted.

  The adjustment screw 192 is a screw for moving the upper and lower blocks 190, and thereby the degree of relaxation of the spring 186 can be adjusted via the upper and lower blocks 190. In the present embodiment, the head 192a of the adjustment screw 192 is disposed on the outer surface of the column member 180 (see FIG. 8B). Thus, when adjusting the force (relaxation degree) of the spring 186, the adjustment screw 192 can be easily operated from the outside of the column member 180 without performing work such as disassembling the column member 180 or the support member 160. Can do.

  FIG. 9 is a diagram for explaining adjustment of the spring 186 using the upper and lower blocks 190 and the adjustment screw 192. In FIG. 9A, the upper and lower blocks 190 are located above, and the spring 186 is extended to the maximum. In other words, the spring 186 has a large force for biasing the sliding member 162 (supporting member 160) upward.

  When adjusting the force (relaxation degree) of the spring 186 from this state, the head 192a (see FIG. 8B) of the adjustment screw 192 provided on the outer surface of the column member 180 is used using a tool (not shown). Rotate. As a result, the upper and lower blocks 190 move in the direction of the arrow, and the spring 186 contracts in the direction of the arrow. By the above operation, the upper and lower blocks 190 reach the lowermost part of the moving range as shown in FIG. 9B, and the spring 186 is in the most contracted state. Therefore, the force with which the spring 186 biases the sliding member 162 (supporting member 160) upward can be minimized.

  Further, as shown in FIGS. 9C and 9D, the tip of the spring engaging portion 190a of the upper and lower blocks 190 can be observed from the observation window 198a provided in the cover 198 of the column member 180 in the above operation. it can. Thereby, the user can confirm the force (relaxation degree) of the spring 186 and can grasp the state of the spring 186 easily and reliably.

  As described above, in the present embodiment, by rotating the adjustment screw 192, the vertical block 190 is moved up and down, and the spring 186 biases the sliding member 162 (supporting member 160) in the link mechanism. That is, it is possible to adjust the force that raises the mounting member 150 supported by the support member 160. Thereby, the force of the spring 186 can be adjusted according to the weight (amount) and type of the object to be stored in the mounting member 150.

  The rail member 200 (rail) is disposed on the wall plate 130a in the base cabinet 130 (storage) (see FIG. 3), and guides the upper pulley 170 and the lower pulley 172. FIG. 10 is a diagram showing details of the rail member 200. As shown in FIG. 10, the rail member 200 has a plurality of rails composed of a plurality of grooves formed in a plate-like base, that is, an upper rail 210 and a lower rail 220. Thereby, the upper pulley 170 and the lower pulley 172 (plurality of pulleys) can respectively travel (guide) to the upper rail 210 and the lower rail 220 (plurality of rails), and only one pulley is used. As compared with the above, it is possible to improve the stability when the arm 168 operates.

  Further, since the upper pulley 170 travels on the upper rail 210 and the lower pulley 172 travels on the lower rail 220, play of these pulleys is moderately suppressed, so that rattling of the arm 168 is reduced and It is possible to prevent rotation (movement) in an unintended direction. Furthermore, by forming the upper rail 210 and the lower rail 220 with grooves, the upper and lower sides of the upper pulley 170 and the lower pulley 172 can be restricted simultaneously. Therefore, the upper rail 210 and the lower rail 220 can function when the upper pulley 170 and the lower pulley 172, and thus the support member 160 are pushed up and down as the drawer 134 is put in and out.

  The upper rail 210 has an inclined portion 210b that rises toward the front side at the center, a front horizontal portion 210c that guides the upper pulley 170 substantially horizontally at the front side of the inclined portion 210b, and a rear side from the inclined portion 210b. On the side, a rear horizontal portion 210a for guiding the upper pulley 170 substantially horizontally is provided. Similar to the upper rail 210, the lower rail 220 also has a back horizontal portion 220a for guiding the lower pulley 172, an inclined portion 220b, and a front horizontal portion 220c.

  With the above configuration, when the drawer 134 is pulled out, the pulleys (upper pulley 170 and lower pulley 172) provided on the arm 168 move on the rail member 200 from the back side of the drawer 134 to the near side along the shape thereof. It becomes. When the pulley reaches the inclined portions 210b and 220b, the pulley then moves up along the shape (inclined) of the inclined portions 210b and 220b, so the arm 168 also moves in the horizontal direction and moves upward. Will be. Along with this, the support member 160 connected to the arm 168 is guided by the column member 180 and moves upward (rises), and the mounting member 150 supported by the support member 160 rises. Therefore, the mounting member 150 arranged inside the drawer 134 can be raised and lowered with a simple mechanism using the rail member 200, the pulley, and the arm 168.

  The interval between the inclined portion 210b of the upper rail 210 and the inclined portion 210b of the lower rail 220 is formed such that the horizontal width W2 thereof substantially coincides with the horizontal interval W1 between the upper pulley 170 and the lower pulley 172. The Further, the height interval H2 between the front horizontal portion 210c of the upper rail 210 and the front horizontal portion 220c of the lower rail 220, and between the rear horizontal portion 210a of the upper rail 210 and the rear horizontal portion 220a of the lower rail 220, is The pulley 170 and the lower pulley 172 are formed so as to substantially coincide with the interval H1 in the height direction. As a result, the upper pulley 170 and the lower pulley 172 arranged so that the arm 168 is in a substantially horizontal posture moves along the inclined portions 210b and 220b having a horizontal width substantially equal to the interval therebetween. While rising. Therefore, the two pulleys can be simultaneously guided up and down, and the arms 168 can be raised and lowered while maintaining the level. Therefore, the arm 168 can move up and down while maintaining a substantially horizontal posture, and the mounting member 150 can be moved up and down in a substantially vertical direction.

  In order to keep the arm 168 horizontal, it is preferable to widen the horizontal interval W1 between the upper pulley 170 and the lower pulley 172, and according to this, the inclined portion 210b of the upper rail 210 and the inclined portion of the lower rail 220 are arranged. The horizontal width W2 of 210b is also increased.

  Further, in the present embodiment, the back side horizontal portions 210a and 220a, the inclined portions 210b and 220b, and the front side horizontal portions 210c and 220c are substantially straight lines, and their intersections (bending points) are rounded. At this time, it is preferable that the radius of curvature of the radius is larger than the radius of the upper pulley 170 and the lower pulley 172 (bending is gentle). However, except that the inclined portions 210b and 220b have a smooth curve that draws an S-shape, and that the rear horizontal portions 210a and 220a and the front horizontal portions 210c and 220c are also inclined, bent, or curved. is not.

  The upper rail 210 and the lower rail 220 are provided with ribs 212 and 222 for preventing wheel removal, respectively. FIG. 11 is a diagram showing details of the ribs 212 and 222. As shown in FIG. 11, in the present embodiment, the ribs 212 and 222 are provided upright from the lower edge of each of the upper rail 210 and the lower rail 220 toward the upper edge (opposing edge). Thereby, the operation | movement to the horizontal direction of the upper pulley 170 and the lower pulley 172 is controlled. Therefore, the pull-out (drop-off) from the upper rail 210 of the upper pulley 170 and the lower rail 220 of the lower pulley 172 is reliably prevented, and the drawer 134 can be operated smoothly.

  In the present embodiment, the ribs 212 and 222 are provided on the lower edge of each of the upper rail 210 and the lower rail 220. However, the present invention is not limited to this. It suffices to be provided on either one of the upper edges. Thereby, it can be provided at both the lower and upper edges, and it can be prevented that the pulley bites the upper and lower ribs and becomes difficult to move.

  The upper rail 210 has a recess 214 formed at the front end thereof. FIG. 12 is a diagram showing details of the recess 214. As shown in FIG. 12A, the recess 214 has a radius of curvature larger than that of the upper pulley 170 and is curved downward. Thereby, as shown in FIG. 12B, when the entire drawer 134 is taken out from the base cabinet 130 (storage), the upper pulley 170 passes through the recess 214, so that the contact between the upper pulley 170 and the rail member 200 is prevented. It can be avoided and damage can be prevented.

  More specifically, when the drawer 134 is attached to the base cabinet 130 in the normal state, the upper pulley 170 and the lower pulley 172 are in a position connected to the arm 168 indicated by a broken line in FIG. Present on the upper rail 210 and the lower rail 220. When the drawer 134 is taken out from the base cabinet 130, the arm 168 lifted together with the drawer 134 is in a state indicated by solid lines in FIG. 12C, whereby the upper pulley 170 and the lower pulley 172 are indicated by such solid lines. The upper pulley 170 moves to the position connected to the arm 168 and moves in the recess 214. Therefore, as described above, contact between the upper pulley 170 and the rail member 200 can be avoided. In the present embodiment, the recess 214 is provided only on the upper rail 210, but may be provided on the lower rail 220.

  Furthermore, in this embodiment, the groove | channel which comprises the upper rail 210 and the lower rail 220 has the bottoms 216 and 226, ie, is bottomed (refer FIG. 10). Therefore, when the upper pulley 170 and the lower pulley 172 move on the upper rail 210 and the lower rail 220, the friction between the wall plate 130a (wall surface) of the base cabinet 130 (storage) and the upper pulley 170 and the lower pulley 172 is caused. Can be prevented. This prevents wear of the wall plate 130a (in many cases, wood) and is slid by the bottom surfaces (bottoms 216 and 226) of the grooves (upper rail 210 and lower rail 220) of the rail member 200 (in most cases, resin). It becomes possible to reduce the dynamic friction and ensure a smooth operation.

  In this embodiment, the bottoms 216 and 226 are provided on the upper rail 210 and the lower rail 220 of the rail member 200. However, the present invention is not limited to this, and the bottom may be omitted. FIG. 13 is a diagram illustrating another example of the rail member. In FIG. 13, elements having substantially the same functions and configurations as the rails 200 are denoted by the same reference numerals, and description thereof is omitted.

  As shown in FIG. 13, the upper rail 310 and the lower rail 320, which are grooves formed in the rail member 300, do not have a bottom. This makes it possible to reduce the weight of the rail member 300 and reduce the cost required for this.

  FIG. 14 is a view for explaining attachment of the rail member 200 to the base cabinet 130. As shown in FIG. 14, when the rail member 200 is attached (arranged) to the base cabinet 130, the rear end of the plate-like base of the rail member 200 is connected to the back plate 130b (rear surface) in the base cabinet 130 (storage). ). Thereby, when attaching the rail member 200 to the wall board 130a (wall surface) of the base cabinet 130, it can abut against the back board 130b, can be positioned, and the rail member 200 can be attached easily and correctly.

  In this embodiment, the rail is composed of two rails (upper rail 210 and lower rail 220), but the present invention is not limited to this. The number of rails may be one or more, and when it is desired to improve the operation stability of the arm 168 as described above, it is preferable to provide two or more rails.

  The operation of the mounting member 150 by the lifting mechanism in the base cabinet 130 having the above configuration will be described. FIG. 15 is a view for explaining the operation of the mounting member 150 by the elevating mechanism when the drawer 134 is pulled out. Although the spring 186 can hardly be observed from the appearance in the above configuration, the spring 186 is illustrated in FIG. 15 for convenience of explanation.

  FIG. 15A shows a state in which the drawer 134 is accommodated in the base cabinet 130. At this time, the support member 160 (sliding member 162 and the like) is urged upward by the spring 186, but the upper pulley 170 and the lower pulley 172 are in the rear horizontal portions 210a and 220a of the rail member 200. The position in the height direction is restricted. Therefore, the mounting member 150 is in the most lowered state.

  FIG. 15B shows a state in which the drawer 134 is pulled out. At this time, since the upper pulley 170 and the lower pulley 172 are in the inclined portions 210b and 220b, when the drawer 134 is pulled out, the arm 168 rises, and the support member 160 and the mounting member 150 also rise. That is, the force that pulls out the drawer 134 is converted into a force that raises the placement member 150. At this time, since the support member 160 (sliding member 162 and the like) is biased upward by the link mechanism, the force required to pull out the drawer 134 can be reduced.

  FIG. 15C shows a state in which the drawer 134 is substantially pulled out. At this time, the pulleys 170 and 172 are in the front horizontal portions 210 c and 220 c of the rail member 200. Accordingly, the front horizontal portions 210c and 220c support the weight of the mounting member 150 in the state in which the drawer 134 is pulled out, and the drawer 134 can be prevented from returning into the base cabinet 130. At this time, the height of the sliding member 162 reaches the upper limit due to the movement limit of the sliding member 162 relative to the column member 180 or the reduction limit of the spring 200. Therefore, even if the lower pulley 172 protrudes from the front end of the rail member 200, there is no problem.

  When the drawer 134 is housed in the base cabinet 130, the above operation is reversed. When the drawer 134 is pushed in from the pulled-out state (see FIG. 15C), the pulleys 170 and 172 reach the inclined portions 210b and 220b as shown in FIG. 15B. Then, since the pulleys 170 and 172 are guided by the inclined portions 210b and 220b and descend, the arms 168 are pulled down while maintaining a horizontal posture. As a result, the support member 160 and thus the placement member 150 are lowered by simply pushing the drawer 134.

  As described above, according to the storage (base cabinet 130) according to the present embodiment, when the drawer 134 is pulled out, the pulleys (upper pulley 170 and lower pulley 172) provided on the arm 168 pull out on the rail member 200. The support member 160 that moves from the back side of 134 to the near side and is connected to the arm 168 is guided by the column member 180 and moves upward (rises). Therefore, the mounting member 150 disposed inside the drawer 134 and supported by the support member 160 can be moved up and down by a simple mechanism using the rail member 200, the pulley, and the arm 168, and is stored in the mounting member 150. It is possible to raise the stored object and make it easier to take out. At this time, since the mounting member 150 moves up and down in accordance with the operation of taking in and out the drawer 134, the operation is simple and easy, and the height is raised to a sufficient height necessary for taking out the storage object without bending. Thereby, the usability of the drawer in the low position can be improved.

  In the above-described embodiment, the drawer 134 of the base cabinet 130 has been described. However, the placement member 150 may be provided in another drawer 132 or floor container 136, and the stove cabinet 120 or sink cabinet which is another storage. A mounting member 150 may be provided in the 140 drawers.

  As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to the example which concerns. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention. Understood.
