Description

  The present invention relates to a lifting cabinet with a door, and more particularly, to a lifting cabinet with a door that improves the opening and closing operation of the door.

  Conventionally, as this type of elevator cabinet with a door, an inner box is provided in an outer box provided with a door so that it can be raised and lowered by a motor, and when the inner box is lowered, the front of the inner box can be exposed from the outer box as a whole. It is known that the door which covers the front of the inner box when the inner box is raised and stored can be rotated in the front-rear direction with the upper end as a fulcrum via a hinge connected to the outer box. Yes.

  With such a configuration, means for preventing the danger of interference between the door and the stored item in the forward projecting state when the inner box is raised and lowered is necessary. For example, when applied to a tableware dryer, if the inner box is raised while the opening of the door is insufficient and the tableware stored in the inner box is protruding forward, the tableware will hit the door and break. There is danger.

Therefore, the outer box has a door that covers the front surface of the inner box when the inner box is raised and stored, and the door can be rotated in the front-rear direction with the upper end as a fulcrum through a hinge connected to the outer box. In addition, the door and the inner box are connected by a link composed of a plurality of arms, and the door can be rotated in the closing direction when the inner box is raised and lowered, and in the opening direction when lowered, the link. Has proposed a lifting cabinet with a door configured to stop the door at the maximum opening angle position in the middle of the rising stroke of the inner box ( Patent Document 1 ).

However, the thing of patent document 1 gets in the way because the lower part of the door when the door is opened largely projects forward in the taking in and out operation of the stored items in the inner box. In particular, there is room for improvement in the operation of putting in and out the stored items in the upper part because it is difficult to see unless it is opened wide.

Patent Document 2 proposes a lifting and lowering storage device that raises and lowers the inner box in conjunction with a door that opens and closes while maintaining a vertical state. This device manually opens and closes the door, It is not suitable for storing heavy items to lift and lower, and is not suitable for installing the device at a high place because it is manually moved up and down, and there is a lifting guide mechanism used for lifting and lowering the lifting shelf. Since it is composed of a large number of link members, it is not suitable for an inner box lifting mechanism by a motor.

  Next, the door opening / closing mechanism 6 for driving the door 5 will be described in detail.

As shown in FIG. 6, a pair of door opening / closing mechanisms 6 are provided between the outer box 2 and the inner box 3, and are composed of an operating arm mechanism 61 and an opening / closing arm mechanism 62. An operation member attached to the side plate 3c, for example, an operation roller 61a, and a non-linear shape having a _first inflection point p ₁ and a second inflection point p ₂ that abut against the operation roller 61a in a non-constrained state. and it has the working side portions 61b _1, is supported on the box 2 at one end near, has an operating arm 61b which is rotated by the operation roller 61a via the actuating side portion 61b _1, further for operating one end of the arm 61b spring 61b ₄ for urging the counterclockwise direction in the drawing is mounted, straight guide groove 61b5 is provided in the vicinity of the other end portion.

Therefore, the actuator roller 61a is in accordance with the elevation of the inner box 3, presses the inclined portion 61b ₂ of the actuating side portion 61b _1, by rotating the actuating arm 61b, the inflection point _{p 2} points in the vicinity of the end portion from the _{p 3} without rotating the actuating arm 61b in the vertical portion 61b ₃ between, keeping the rotation angle. By providing a spring 61b _4, actuating arm 61b is biased in the counterclockwise direction, since the door 5 is held in the closed state, even if the inner box 3 vibrates due to an earthquake, tableware door 5 The movement is suppressed, and it does not fall and is safe.

  The open / close arm mechanism 62 includes a first open / close arm 62a and a second open / close arm 62b, both of which are substantially triangular.

The first opening / closing arm 62 a has one end pivotally supported by the outer box 2 and the other end pivotally supported by the door 5, and a long-hole arc guide that guides the guide pin 62 a ₁ attached to the outer box 2. It is provided grooves 62a _2. By providing the guide grooves 62a _2, and anti-vibration lateral door during door closing, it is possible to regulation opening angle of the door, it is possible to also fall prevention of tableware by an earthquake.

Second switching arm 62b is pivotally supported at a first end outer box 2, the second end portion is rotatably supported in the door 5, further guide pin 62b ₁ is provided on the third end It is, by engaging the guide pin 62b ₁ in the guide groove 61b ₅ of the working arm 61b, actuating arm 61b and the second switching arm 62b is connected.

Accordingly, the length (distance) L1 of the pivot support position of the first opening / closing arm 62a pivotally supported by the outer box 2 and the pivot support position of the second opening / closing arm 62b, and the first pivot pivotally supported by the door 5. The length (distance) L2 of the pivot support position of the first opening / closing arm 62a and the pivot support position of the second opening / closing arm 62b, the arm (length) L3 of the first opening / closing arm 62a, and the second The forever linkage is formed by the arm Lb4 of the open / close arm 62b. As a result, the second opening / closing arm 62b is rotated through the guide groove 61b ₅ and the guide pin 62b ₁ in accordance with the rotation of the operating arm 61b, and the door 5 is in a vertical state or slightly inclined state by the forver linkage. It is designed to rotate by a predetermined angle while maintaining By providing the guide groove 62a in which the guide pin 62b ₁ is movable, the door 5 can be pressed against the opening of the outer box 2. Incidentally, if the arm L3 of the first opening and closing arm 62a of the arm length of L 4 of the second switching arm 62b to the same, the door is rotated while maintaining the vertical state, L 3 _{<L 4} In this case, the door 5 is slightly tilted from the vertical to the right. In the present embodiment, the description will be made assuming that L ₃ <L ₄ .

  As described above, since the door is closed by an arm configuration using its own weight, the structure is simple and the door can be easily opened and closed.

FIG. 9 to FIG. 11 constitute a part of the outer box 2 and show a mounting state of the front plate 2b provided on the upper portion of the door 5, and this front plate 2b has a front plate stopper 2b ₂ attached in advance. The front plate stopper receiver 2b ₃ attached to the side surface 2c of the outer box 2 is engaged and temporarily fixed, and the front plate stopper receiver 2b ₃ and the front plate stopper 2b ₂ are screwed together to form the outer box. 2 is attached. As a result, the assembly is easy, and it is necessary to remove and attach the front plate particularly during maintenance of the lifting mechanism. However, since the front plate can be temporarily fixed from the front, it can be easily performed by one person.

  Moreover, the usage method of the raising / lowering type tableware storage cabinet based on this invention is demonstrated.

  As shown in FIGS. 4 and 5, the user lowers the inner box 3 accommodated in the outer box 2 and removes the inner box 3 from the outer box 2 in order to put in and out dishes. Make it appear.

  The lowering of the inner box 3 is mainly performed by the weight of the inner box 3 by driving the motor 4a via the operation lever 4i and the control device 4j, rotating the winding drum 4d, and feeding out the belt 4b.

As shown in FIGS. 7 and 8, along with the descent of the inner box 3 is attached to the side plate 3c of the inner box 3, also drops actuator roller 61a which is in contact with the inflection point p ₁ of the working arm 61b, while the inclined portion 61a ₂ until reaching the inflection point _{p 2} are in contact, the actuator roller 61a causes the figure rotates in the clockwise direction against the actuating arm 61b of the spring 61b _4.

  As the operating arm 61b rotates, the open / close arm mechanism 62 moves in a forver linkage, and the first open / close arm 62a and the second open / close arm 62b rotate around a fulcrum attached to the outer box 2. The door 5 is moved (rotated) while maintaining a slight inclination, and the lower end 5a is moved up.

Furthermore, although the inner box 3 drops, the vertical portion 61b ₃ between the points _{p 3} near the end of the inflection point _{p 2} is the operating arm 61b, but the actuator roller 61a is in contact with the actuating arm 61b, This further without pressing in the clockwise direction, rather than the rotation of the rotating or more actuating arm 61b in between the inclined portion 61b _2, therefore, no rotation of the closing arm mechanism 62, the door 5 is actuated when the roller 61a is in the inflection point p _2, it keeps the open state.

  Thus, when the inner box 3 is lowered to the middle of the entire lowering range, for example, to 1/3, the door 5 is in the fully opened state, so that the tableware on the receiver 8 moves the inner box 3 to the lowest end. It can be taken in and out without being lowered.

As shown in FIGS. 2 and 3, when the operating roller 61 a reaches the point p ₃ , the lowering of the inner box 3 is completed, and the front surface of the inner box 3 is entirely exposed from the outer box 2.

  In this way, with the door 5 in a slightly inclined state and the lower end portion 5a of the door 5 raised, the user takes in and out the receiving tool 8 and tableware. Therefore, when the tableware is taken in and out, the lower end portion 5a of the door 5 does not protrude greatly forward, so that it does not get in the way.

  After completion of taking in and out of the tableware, the motor 4a is again driven through the operation lever 4i and the control device 4j, the take-up drum 4d is rotated, the belt 4b is taken up, and the inner box 3 is raised.

In the ascending process, as indicated by a dotted line in FIG. 7, the operating roller 61 a that contacts at the point p _{1 of the} operating arm 61 b rises along the vertical portion 61 b ₃ as the inner box 3 rises. At this time, since the operating arm 61b is kept as it is, the opening / closing arm mechanism 62 is not operated, and the door 5 is also kept open. Therefore, there is no interference between the door 5 and stored items such as tableware in the forward projecting state, danger can be prevented, and the operating roller 61a and the operating arm 61b are in contact with each other in an unconstrained state. Even when a stored item longer than the depth of the box 3 is stored, the open / close arm mechanism 62 and the door 5 are moved by the stored item and the interference is mitigated, which is safe.

Further, the inner is box 3 increases also the actuator roller 61a rises, when the actuator roller 61a is in between the inflection point p ₂ from the point p ₃ in the vicinity of the end portion, turn the actuating arm 61b in the counterclockwise direction Without being moved, the opening / closing arm mechanism 62 and the door 5 are not rotated, and the door 5 is kept open.

  In this way, when the inner box 3 rises to the middle of the entire ascending range, the tableware can be pushed inward even if it protrudes forward from the inner box 3.

The inner box 3 continues to rise, past the actuator roller 61a is elevated inflection point p _2, reaches the inclined portion 61a _2, operating arm 61b is rotated in the counterclockwise direction, the opening and closing arm mechanism 62 The door 5 is actuated and closed while rotating counterclockwise by its own weight, and when the inner box 3 is lifted and the inner box 3 is stored, the operating roller 61a is moved to the inflection point p1. The door 5 completely closes the opening and maintains this state.

  As described above, since the inner box 3 is moved up and down by the motor 4a, the inner box 3 can be easily moved up and down even when a heavy storage item is stored in the inner box 3, and is suitable for installation in a high place. Furthermore, since the elevating mechanism 4 that elevates and lowers the inner box 3 is constituted by the motor 4a and the belt 4b, it is suitable for electric operation, has a simple structure, and is durable.

  As described above, according to the present embodiment, the inner box can be moved up and down by a motor, the door does not get in the way when the stored item is put in and out of the inner box, and the stored item at the upper part of the inner box is further removed. An elevator cabinet with a door that can be seen well and is easy to use is realized.
