Description

  The present invention relates to a pressing member that is provided so as to be freely pressed on an interior panel of an automobile or the like and an operation panel of various electronic devices.

  Conventionally, as the pressing member, for example, one described in Patent Document 1 is known. The pressing member includes a button main body and a pair of support shafts protruding to the back side of the button main body, and the support shafts are inserted into insertion holes formed in the transceiver main body (operation panel), thereby The movement of the pressing member in the pressing direction along the support shaft is guided.

  In the pressing member having a plurality of supporting shafts as described above, a specific supporting shaft (hereinafter referred to as a guide shaft) serves as a guide for guiding the pressing member along the pressing direction, and the other supporting shaft (hereinafter referred to as a supporting shaft). It is also known that an anti-rotation shaft) is used to prevent rotation of the pressing member around the guide shaft, and both the shafts are formed integrally with the pressing member.

When this type of pressing member and the operation panel that holds the pressing member are integrally molded, there are variations in the pitch dimension between the guide shaft and the non-rotating shaft and the pitch dimension between both insertion holes through which these guide shafts are inserted. If this is unavoidable and the fitting between these two shafts and the two insertion holes is tightened, the two shafts cannot be inserted. Therefore, in the pressing member, a clearance having a size in consideration of the variation in the pitch dimension is provided between the rotation-preventing shaft and the insertion hole through which the clearance is inserted.
JP-A-5-266754

  In the pressing member, it is necessary to provide a considerably large clearance in order to absorb the variation in the pitch dimension, and since the detent shaft can freely move in the insertion hole by the clearance, the pressing surface of the pressing member When the range separated from the guide shaft is pressed, the rotation preventing shaft is inclined with respect to the insertion hole with the guide shaft as a fulcrum, so that the pressing member is easily tilted with respect to the operation panel. There is a possibility that the sliding resistance with the insertion hole increases and the pressing member cannot be smoothly pressed.

  In particular, in recent years, it has been demanded to expand the pressing surface. With this expansion, the probability of pressing the portion of the range of the pressing surface away from the guide shaft is increased, and the pressing member is more easily tilted. There is a tendency.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a pressing member that can achieve both rotation prevention and smooth pressing operation and a pressing operation device including the pressing member.

In order to solve the above-mentioned problems, the present invention is such that the front surface is a pressing surface that receives a pressing operation, and includes a guide shaft and a non-rotating shaft protruding from the back surface, and both the shafts are inserted into the operation panel The first member including the guide shaft in a pressing member that is freely pressable with respect to the operation panel along the axial direction of the guide shaft and is restricted from rotating around the guide shaft with respect to the operation panel. And the second member including the detent shaft are configured as separate members, and these members are connected so that the pitch between the guide shaft and the detent shaft is movable, and the first member or the second member One of the two members is a button main body having the pressing surface formed on the surface thereof, and the other is driven by the pressing operation with respect to the button main body and moves along the pressing surface. The movable member includes a substrate portion on which the guide shaft or the detent shaft is erected, and the substrate portion is disposed along the back surface of the button body, and the guide A first shaft that is movably attached to the button main body along a direction orthogonal to both the shaft and the non-rotating shaft, and is orthogonal to a plane including both the guide shaft and the non-rotating shaft. A bulging portion that bulges in an arc shape toward both sides of the direction, and a first clamping portion that sandwiches the bulging portion from the outside of the first direction on the back surface of the button body; and the first direction a second clamping portion from the outer sandwiching said substrate portion in a portion other than the bulge portion is provided in the substrate portion along the first clamping portion and a second clamping portion and characterized that you sliding A pressing part is provided.

  According to the present invention, the first member and the second member are moved relative to each other by rotating the first member and the second member even when the pitch dimension of the insertion portion of the guide shaft and the detent shaft in the operation panel varies. By adjusting the pitch dimension with the stop shaft, the both shafts can be inserted, so that the necessary clearance between the detent shaft and the operation panel can be reduced.

  Therefore, in the present invention, since the clearance for absorbing the variation in pitch dimension can be reduced, even when the range of the pressing surface that is separated from the guide shaft is pressed, the detent shaft with respect to the operation panel The tilting of the pressing member can be prevented and the tilting of the pressing member accompanying this tilting can be prevented, and the pressing operation of the pressing member can be guided by both the guide shaft and the non-rotating shaft. It can be done smoothly.

  Therefore, according to the present invention, it is possible to achieve both rotation prevention and smooth pressing operation.

Specifically, in the present invention, one of the first member and the second member is a button body having the pressing surface formed on the surface thereof, and the other is used for pressing the button body. The movable member is driven and is movably attached along the pressing surface .

Therefore , by forming a guide shaft or a detent shaft on the button body having the pressing surface, a pressing member having a function of adjusting the pitch dimension can be configured by the button body and the movable member. The number of parts can be minimized.

In the present invention, the movable member includes a substrate portion on which the guide shaft or the detent shaft is erected, and the substrate portion is disposed along the back surface of the button body, and the guide shaft and It is attached to the button body so as to be movable along a direction orthogonal to both axes of the detent shaft.

Therefore, it is possible to achieve both the rotation prevention of the button body and the smooth pressing operation with a simple configuration in which the substrate portion of the movable member is movably attached along the back surface of the pressing surface.

Further, in the present invention, on the back surface of the button main body, a sandwiching portion that sandwiches the substrate portion in a direction perpendicular to a plane including both axes of the guide shaft and the rotation preventing shaft is erected, and along the sandwiching portion. The board part slides.

Therefore, it is possible to regulate the movement of the substrate portion in the direction orthogonal to the plane including the two axes by the sandwiching portion erected on the back surface of the button body.

The movable member is preferably attached to the button body in a state in which movement along the first direction is restricted.

  According to this configuration, since the movement of the movable member along the direction orthogonal to the plane including the guide shaft and the detent shaft is restricted, the button body moves around the guide shaft when the pressing member is attached to the operation panel. It is possible to reliably prevent the rotation.

  That is, when the pressing member according to this configuration is attached to the operation panel, relative movement in the tangential direction of a circle centering on the axis of the guide shaft is restricted in the relationship between the button body and the movable member. Since the movement of both of the movable members is restricted with respect to the operation panel by the guide shaft and the non-rotating shaft, the rotation of the button body with respect to the operation panel can be prevented.

Note that “regulation of movement along the direction (first direction) perpendicular to the plane including both axes of the guide shaft and the detent shaft” does not mean that movement in the direction is completely impossible, but a button This is intended to include movement within a range in which the main body is allowed to rotate.

  Although the shape of the pressing surface is not particularly limited, the pressing surface has a shape extending in a specific direction, and the guide shaft and the detent shaft are arranged side by side in the specific direction, and the movable member Is preferably movable along the specific direction with respect to the button body.

  According to this configuration, since the guide shaft and the detent shaft are arranged side by side along the longitudinal direction of the pressing surface, the button body is pressed relatively smoothly regardless of the position of the pressing surface to be pressed. be able to.

  That is, in the above-described configuration, the guide shaft or the detent shaft is laid out near either end in the longitudinal direction of the pressing surface. When the clearance required to absorb the variation in pitch dimension is provided between the buttons, the button body can be guided along the guide shaft when the end on the guide shaft side is pressed. When the end of the shaft was pressed, the tilt of the detent shaft with the guide shaft as a fulcrum was a hindrance to the smooth push operation. In this configuration, the pitch between the detent shaft and the guide shaft Due to the adjustable dimensions, it is not necessary to provide the clearance between the detent shaft and the operation panel, and the button body is pressed not only by the guide shaft but also by the detent shaft. Since it is possible to guide, even if any of the end portions in the longitudinal direction of the pressing surface is pressed, it means that the pressing operation is performed relatively near the guide shaft or the non-rotating shaft. The button body can be pressed relatively smoothly along the line.

  The button body is formed with a holding portion having a holding surface facing the back surface of the button body, and the substrate portion is held between the back surface of the button body and the holding surface. It is preferable to follow the pressing operation of the button body.

  According to this configuration, the button body and the movable member can be moved integrally during the pressing operation.

  Another aspect of the present invention is a pressing operation device having the pressing member and an operation panel that holds the pressing member, the operation panel including an insertion hole through which the guide shaft is inserted, and the rotation The pressing operation device is characterized in that a rotation stop hole through which the stop shaft is inserted is formed.

  ADVANTAGE OF THE INVENTION According to this invention, the press operation apparatus which can make the rotation stop of a press member and smooth press operation compatible can be provided.

  The pressing operation device further includes a main board disposed on a back surface of the operation panel, and a switch member provided on the main board, and the switch member on the end surface of the guide shaft by a pressing operation of the pressing member. Is preferably pressed.

  According to this configuration, the pressing member can be smoothly pressed when the switch member is pressed.

  According to the present invention, it is possible to achieve both the rotation prevention of the button body and the smooth pressing operation.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

  FIG. 1: shows the audio equipment for vehicles which concerns on embodiment of this invention, (a) is a top view, (b) is Ib-Ib sectional view taken on the line of (a), (c) is Ic- of (a). It is Ic sectional drawing. FIG. 2 is a cross-sectional view taken along the line II-II in FIG.

  Referring to each drawing, audio device 1 includes main board 2, operation panel 3 covering the surface of main board 2, and a pair of switches (switch members) 2a and 2b mounted on main board 2. An operation button (pressing member) 4 to be pressed is provided.

  The operation panel 3 is a synthetic resin panel that opens to the front side and has a concave portion 5 that is substantially rectangular in plan view. In the following description, the longitudinal direction of the recess 5 is defined as the left-right direction, the opening side (surface side) of the recess 5 is defined as the front, and the direction orthogonal to the left-right and front-rear directions is described as the up-down direction.

  The operation panel 3 is formed with a pair of left and right sleeves 6 and 7 extending from the bottom plate 5a of the recess 5 to a position before the switch 2a. Each of the sleeves 6 and 7 is formed in a cylindrical shape extending in the front-rear direction, and the inner cavity portion serves as an insertion hole 6a and a rotation prevention hole 7a for guiding an operation button 4 described later.

  The operation button 4 includes a pair of guide shafts 11 and a rotation-preventing shaft 17 protruding rearward, and these shafts 11 and 17 are inserted into the insertion hole 6a and the rotation-prevention hole 7a of the operation panel 3, respectively. The operation panel 3 can be pressed and operated along the axial direction (front-rear direction) of the guide shaft 11, and the rotation about the guide shaft 11 is restricted with respect to the operation panel 3.

  Specifically, the operation button 4 includes a button main body (first member) 8 including a guide shaft 11 and a movable member (second member) 9 including a detent shaft 17. The pitch dimension P1 between the guide shaft 11 and the detent shaft 17 can be adjusted.

  The button main body 8 includes a pressing portion 10 that can be moved in and out in the concave portion 5, a guide shaft 11 that extends rearward (back side) from the pressing portion 10, and a pair of left and right tongues that penetrate the bottom plate 5 a of the concave portion in the front-rear direction. Part 12, and the locking claws 12 a of these tongue parts 12 are locked to the rear surface of the bottom plate 5 a, thereby preventing the tongue 12 from coming off from the operation panel 3.

  The pressing portion 10 is formed in a substantially rectangular shape in plan view corresponding to the planar shape of the concave portion 5, and the front surface thereof is a pressing surface 10a that receives a pressing operation.

  The pressing portion 10 is provided with a pair of upper and lower clamping plates (clamping portions) 14 protruding from the rear surface. These sandwiching plates 14 allow the movable member 9 to slide in the left-right direction while restricting the movable member 9 from moving up and down relative to the button body 8 by sandwiching the movable member 9 described later vertically. Yes.

  The guide shaft 11 is formed in a cylindrical shape extending in the front-rear direction, is inserted through the insertion hole 6a of the operation panel 3, and its lower end is in contact with the front surface of the switch 2a. Therefore, the guide shaft 11 presses the switch 2a at the lower end thereof in accordance with the pressing operation of the pressing portion 10, while the compression spring (not shown) built in the switch 2a is attached in response to the release of the pressing force. Returning to the forward position (position defined by the locking claw 12a) by the force.

  Further, the guide shaft 11 is formed with a window portion (holding portion) 15 that penetrates the left side surface at a base portion with the pressing portion 10. This window portion 15 forms an opening having a rectangular shape in a side view, and its rear end surface serves as a holding surface 15a (see FIG. 1B) for holding a movable member 9 described later.

  The movable member 9 includes a substrate portion 16 disposed along the rear surface of the bottom plate 5a, and a detent shaft 17 extending rearward from the substrate portion 16.

The substrate portion 16 is a strip-shaped plate member, and a right end portion thereof is inserted into the window portion 15 of the guide shaft 11. Therefore, the substrate portion 16 is held between the rear surface of the pressing portion 10 and the holding surface 15a of the window portion 15, thereby causing the pressing portion 10 to perform a pressing operation and a returning operation (that is, a back-and-forth movement). Will be driven. Note that the upper surface 15 b and the lower surface 15 c (see FIG. 2) of the window portion 15 serve as a second holding portion that holds the side surface of the substrate portion 16 inserted through the window portion 15 and restricts the vertical movement of the substrate portion 16. It is functioning.

Further, the base plate portion 16 is formed with arcuate bulged portions 16a corresponding to the diameter of the detent shaft 17 at the base portion of the detent shaft 17, and these bulged portions 16a It is clamped between both clamping plates (first clamping unit) 14. Therefore, the substrate portion 16 can slide in the left-right direction along the both sandwiching plates 14 with respect to the pressing portion 10 while the vertical movement is restricted by the both sandwiching plates 14.

  The anti-rotation shaft 17 is formed in a cylindrical shape extending in the front-rear direction, is inserted through the anti-rotation hole 7a of the operation panel 3, and its lower end is in contact with the front surface of the switch 2b. Therefore, the detent shaft 17 presses the switch 2b at its lower end in response to the pressing operation of the pressing portion 10, while a compression spring (not shown) incorporated in the switch 2b in response to the release of the pressing force. The urging force returns to the front position (position defined by the locking claw 12a).

  Next, a procedure for assembling the operation button 4 to the operation panel 3 will be described.

  First, by moving the movable member 9 to the left and right with respect to the button body 8, the pitch dimension P1 of the guide shaft 11 and the detent shaft 17 is matched with the pitch dimension of the insertion hole 6a and the detent hole 7a of the operation panel 3. adjust.

  Next, the guide shaft 11 and the rotation prevention shaft 17 are inserted into the insertion hole 6a and the rotation prevention hole 7a from the front until the locking claws 12a of the tongue portions 12 are locked to the bottom plate 5a of the operation panel 3, respectively. Thus, the operation button 4 can be assembled to the operation panel 3.

  Then, in the state where the operation button 4 is assembled in this way, when a rearward external force is applied to the pressing surface 10 a, the operation button 4 is guided along the axial direction of the guide shaft 11 and the detent shaft 17. It will be pushed in.

  At this time, in the said embodiment, since the press surface 10a is made into the rectangle extended in the left-right direction, when either edge part of this press surface 10a is pressed, the end which received pressing force However, in the audio apparatus 1, the guide shaft 11 and the rotation-preventing shaft 17 are arranged side by side so that they are arranged close to the end receiving the pressing force. The operation button 4 can be smoothly pressed along the provided guide shaft 11 or the non-rotating shaft 17.

  When an external force is applied to the operation button 4 in the direction of turning around the guide shaft 11, the left end portion of the button body 8 tries to move in the direction indicated by the arrow Y2, but is movable with the button body 8. Since the movement of the member 9 in the vertical direction (the tangential direction of the circle with the guide shaft 11 as the center) is restricted by the sandwiching plates 14, the two are not displaced relative to each other. Since the movement of the member 9 in both the left and right and up and down directions with respect to the operation panel 3 is restricted by the guide shaft 11 and the detent shaft 17, the rotation of the button body 8 can be prevented.

  As described above, according to the audio device 1, even when the pitch dimension between the insertion hole 6a and the rotation stopper hole 7a varies in the operation panel 3, the buttons formed as separate members from each other. By relatively moving the main body 8 and the movable member 9 and adjusting the pitch dimension P1 between the guide shaft 11 and the detent shaft 17, the shafts 11 and 17 can be inserted into the insertion hole 6a and the detent hole 7a. As a result, the required clearance between the detent shaft 17 and the detent hole 7a can be reduced.

  Accordingly, the audio device 1 can reduce the clearance for absorbing the variation in pitch dimension, so that even when the left end portion of the pressing surface 10a that is separated from the guide shaft 11 is pressed, the rotation is prevented. The tilt of the detent shaft 17 with respect to the hole 7a can be restricted to prevent the operation button 4 from tilting due to this tilt, and the operation button 4 can be pressed by both the guide shaft 11 and the detent shaft 17. It is possible to guide, and the pressing operation of the operation button 4 can be performed smoothly.

  Therefore, according to the audio device 1, it is possible to achieve both the detent of the operation button 4 and the smooth pressing operation.

  Further, in the above embodiment, the guide shaft 11 is formed together with the button body 8 having the pressing surface 10a, so that the button body 8 and the movable member 9 constitute the operation button 4 having the function of adjusting the pitch dimension P1. The number of parts of the operation button 4 can be minimized.

  The movable member 9 is restricted from moving along the direction (vertical direction) perpendicular to the plane including the guide shaft 11 and the detent shaft 17 with respect to the button body 8. It is possible to reliably prevent turning around.

  That is, in the relationship between the button body 8 and the movable member 9, relative movement in the tangential direction (vertical direction) of a circle centering on the axis of the guide shaft 11 is restricted, and both the button body 8 and the movable member 9 are controlled. Since the movement is restricted with respect to the operation panel 3 by the guide shaft 11 and the detent shaft 17, the rotation of the button body 8 relative to the operation panel 3 can be prevented.

  Further, according to the audio device 1, since the guide shaft 11 and the detent shaft 17 are arranged side by side along the longitudinal direction of the pressing surface 10a, the pressing member regardless of the position of the pressing surface 10a to be pressed. Can be pressed relatively smoothly.

  That is, in the audio device 1, the guide shaft 11 is laid out near the right end of the pressing surface 10a, and the detent shaft 17 is arranged near the left end of the pressing surface 10a. Here, the detent shaft 11 and the detent hole 7a are arranged. When the clearance necessary for absorbing the variation in the pitch dimension is provided between the rotation shaft 17 and the guide shaft 11 as a fulcrum, the inclination of the rotation shaft 17 is smooth when the right end of the guide shaft 11 is pressed. However, in the above-described embodiment, the anti-rotation shaft 17 and the anti-rotation hole 7a are caused by the fact that the pitch dimension P1 between the anti-rotation shaft 17 and the guide shaft 11 can be adjusted. It is not necessary to provide the clearance between them, and the pressing operation of the button body 8 can be guided not only by the guide shaft 11 but also by the detent shaft 17. Even when either of the left and right ends is pressed, the guide shaft 11 or the detent shaft 17 is pressed relatively close, and the pressing member is moved relatively smoothly along the shaft 11 or 17. A pressing operation can be performed.

  And in the said audio equipment 1, the rotation prevention of the button main body 8 and smooth press operation can be made compatible by the simple structure of attaching the board | substrate part 16 along the back surface of the press surface 10a movably.

  In the above embodiment, the movable member 9 is attached to the button main body 8 by the window portion 15 of the guide shaft 11. However, the attachment structure of the movable member 9 is not particularly limited. For example, FIG. The mounting structure shown can also be employed.

  3A and 3B show an audio device according to another embodiment of the present invention, in which FIG. 3A is a side sectional view, and FIG. 3B is a sectional view taken along line IIIb-IIIb in FIG. In the following description, the same components as those in the above embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  With reference to FIG. 3, the audio device 18 of the present embodiment is different from the above-described embodiment in that a holding portion 19 that protrudes from the back surface of the pressing surface 10 a is provided.

  Specifically, the holding portion 19 includes a pair of upper and lower protruding pieces 20 and a holding piece 21 protruding from each of the protruding pieces 20 toward the opposite protruding piece 20.

  And the holding | maintenance part 19 hold | maintains the said board | substrate part 16 by inserting the board | substrate part 16 between each protrusion piece 20 and between the front surface 21b of each holding piece 21, and the rear surface of the press part 10. FIG. It is like that. Therefore, the board | substrate part 16 follows the press operation and return operation | movement (namely, front-back operation | movement) of the press part 10. FIG. The inner side surfaces 20 a and 20 b of each protruding piece 20 function as a clamping portion that clamps the side surface of the substrate portion 16 and restricts the vertical movement of the substrate portion 16.

  Also in the audio apparatus 18 configured as described above, the pitch dimension P1 of the guide shaft 11 and the detent shaft 17 can be adjusted by moving the movable member 9 left and right between the protruding pieces 20.

  In addition, in the audio equipment 18 shown in FIG. 3, the mounting structure of the substrate portion 16 by the window portion 15 is omitted, but in addition to the mounting structure of the holding portion 19, a mounting structure by the window portion 15 may be adopted. it can.

  Moreover, in each said embodiment, although the operation button 4 which has the press surface 10a extended in the left-right direction is demonstrated, the shape of the press surface 10a is not specifically limited. For example, even when the pressing surface 10a is circular, the clearance between the detent shaft 17 and the detent hole 7a can be omitted by configuring the button body 8 and the movable member 9 separately. Therefore, unlike the case where the clearance is provided, the tilting of the button body 8 can be suppressed, whereby a smooth pressing operation of the operation button 4 can be realized.

  Further, in each of the above embodiments, the button body 8 having the pressing surface 10a is provided with the guide shaft 11 and the movable member 9 is provided with the anti-rotation shaft 17. On the contrary, the anti-rotation shaft 17 is movable on the button body 8. A guide shaft 11 may be provided on the member 9.
