[Industrial applications]
The present invention is for fixing both ends of a shaft body, which is attached between a pair of wall bodies facing each other and rotatably supports a rotating body provided between the wall bodies, to each of the two wall bodies. More specifically, it is possible to improve the workability of mounting the shaft body, and to provide a rotation control member such as a damper for controlling the rotation movement of the rotation body. The present invention relates to a bearing member capable of facilitating an operation of attaching a control member.
[0002]
Problems to be solved by the prior art and the invention
Conventionally, when a rotating body disposed between a pair of wall bodies is rotatably supported, a shaft body is attached between the two wall bodies, and the rotating body is rotatably supported on the shaft body. In this case, in this case, a shaft body is inserted into a shaft hole directly provided in the both wall bodies, and the shaft body is pierced into a connecting portion of the rotating body to rotatably support the rotating body. In this state, a method is generally employed in which the shaft is attached between the two walls by forming a protrusion or the like on the shaft to prevent the shaft from falling off.
[0003]
For example, FIG. 16 shows an in-car ashtray unit disclosed in Japanese Utility Model Publication No. 2-1223, in which an ashtray body b is rotatably disposed in a case a, and the ashtray body b is turned. It is configured to be pulled out from the case a while moving. In this case, in this ashtray unit, a metal shaft d (shaft) is inserted into shaft holes provided in both side walls c of a case a which is a rotating body, and the shaft d is connected to the ashtray body b (rotating body). The ashtray body b is rotatably supported by penetrating the shaft d. In this state, a protrusion (not shown) is formed on the shaft d inside the both side walls to prevent the ashtray from being removed. The ashtray body b is rotatably attached to the case a by the shaft d by preventing the falling off.
[0004]
However, the ashtray unit in which the ashtray body b is rotatably attached to the case a by such a method has a problem that the assembling work is complicated. That is, when assembling the ashtray unit, first, the ashtray body b is inserted into the case a, and the shaft hole provided in both side walls c of the case a and the shaft insertion hole (not shown) provided in the ashtray body b. The shaft d must be inserted so as to pierce the shaft insertion hole from the shaft hole so that the protrusion d (not shown) is formed on the shaft d in this state. The operation of rotatably connecting the ashtray body b to the case a is very complicated. In particular, the operation of forming the above-mentioned projection for preventing the falling off on the shaft d is performed by using the emergency operation inside the case a or the ashtray body b. It must be performed in a narrow place, and the workability is extremely poor.
[0005]
Therefore, conventionally, as a method for attaching such a shaft d to the side wall c, it is known to use a bearing member e as shown in FIG. That is, the bearing member e has a cylindrical bearing projection g protruding at the center on one surface side of the flat substrate f, and screw insertion holes h, h formed at both ends of the substrate f. A shaft d is disposed between both side walls c (only one side wall is shown in the figure), and the bearing projection g is inserted into a fixing hole i provided in the side wall c from outside the side wall c. The shaft d is inserted into the projection g, and the screws k, k are screwed into the screw holes j, j formed in the side wall c through the screw insertion holes h, h, thereby fixing the bearing member e to the side wall c. Thus, the shaft d is fixed to the side wall c.
[0006]
By using such a bearing member e, the mounting and fixing work of the shaft d can be performed from the outside of the side wall c, and there is no need to provide a projection for preventing the shaft d from dropping off. The workability of the work of rotatably supporting (for example, the ashtray body b in FIG. 16) between the pair of side walls c, c (only one is shown in the figure) can be improved.
[0007]
However, the method using the bearing member e requires the work of screwing the two screws k, k, which increases the number of parts, and the fixing work using the screws cannot always be an easy work. In this case, the simplification of the assembling work and the reduction of the number of parts can improve the working efficiency extremely effectively and effectively contribute to the reduction of the manufacturing cost. It is desired that the number of parts be reduced.
[0008]
As shown in FIG. 16, the ashtray body b (rotating body) is biased by a biasing means (not shown) such as a spring to automatically rotate the ashtray. The body b is rotated in the opening direction, and an oil damper m is attached to the side wall c, and a pinion gear (not shown) of the oil damper m meshes with an arc gear n provided on the ashtray body b. It has also been proposed and practiced to control the rotational movement of the ashtray body b so that the ashtray body b rotates and opens slowly.
[0009]
However, when a rotation urging mechanism using such a damper m is provided, an operation of attaching the damper m by screwing or the like is required in addition to the above-described operation of attaching the shaft d, which further complicates the assembling operation. It will be. For this reason, simplifying the mounting work of such a damper m is extremely effective in terms of improving work efficiency.
[0010]
The present invention has been made in view of the above circumstances, and in the case where a shaft is attached between a pair of opposing walls to rotatably support a rotating body between the two walls, the number of parts is extremely small. The shaft can be mounted between the side walls by a simple operation, and when a rotation control member such as a damper is mounted, the rotation control member can be mounted simultaneously with the mounting operation of the shaft. An object is to provide a bearing member that can improve efficiency.
[0011]
[Means for Solving the Problems]
In order to achieve the above object, the present invention attaches both ends of a shaft that is attached between a pair of wall bodies facing each other and rotatably supports a rotating body disposed between the two wall bodies. A bearing member for fixing to the wall, wherein a circular concave portion is formed on one surface side of the plate-shaped base, A cylindrical bearing projection is provided on one surface side of the plate-shaped base so as to surround the circular recess, and a U-shaped slit is formed on the outer peripheral wall of the bearing projection to be surrounded by the slit. It becomes an elastically deformable locking claw that protrudes part of the outer peripheral wall outward in a mountain shape, By inserting the bearing projection from the outside of the wall into the fixing hole provided in the wall and engaging the locking claw with the peripheral edge of the fixing hole inside the wall, the locking claw and the The peripheral edge of the fixing hole is sandwiched between the plate-shaped base and fixed to the wall, and in this state, the end of the shaft is inserted into the inner space of the bearing projection and fitted into the circular recess. Accordingly, a bearing member is provided which is configured to support and fix an end of the shaft body.
[0012]
In this case, a rotation control member having a pinion gear such as a damper is attached to one surface side of the plate-shaped base, and the pinion gear of the rotation control member is attached to a rack gear provided on the rotation body through a through hole provided in a wall body. By engaging the teeth, the rotation control member controls the rotation of the rotation body.
[0013]
[Action]
As described above, the bearing member of the present invention forms a circular concave portion on one surface side of the plate-like base, A cylindrical bearing projection is provided on one surface side of the plate-shaped base so as to surround the circular recess, and a U-shaped slit is formed on the outer peripheral wall of the bearing projection to be surrounded by the slit. An elastically deformable locking claw that protrudes a part of the outer peripheral wall outward in a mountain shape is provided. And By inserting the bearing projection into the fixing hole provided in the wall from the outside of the wall and engaging the locking claw with the peripheral edge of the fixing hole inside the wall, the locking claw and the plate-shaped member are engaged. The peripheral edge of the fixing hole is sandwiched between the base and the base, and is fixed to the wall. In this state, the end of the shaft is inserted into the inner space of the bearing projection and fitted into the circular recess. Thus, the end of the shaft is supported and fixed.
[0014]
Therefore, by using the bearing member of the present invention, the work of attaching and fixing the shaft can be performed from the outside of the wall, and there is no need to provide a protrusion for preventing the shaft from falling off. The workability of the operation of rotatably supporting between the pair of wall bodies can be improved.
[0015]
Moreover, the bearing member of the present invention A U-shaped slit is formed on the outer peripheral wall of the bearing projection, and an elastically deformable locking claw is provided that protrudes a part of the outer peripheral wall surrounded by the slit outwardly in a mountain shape. Since the bearing projection is inserted into a fixing hole provided in the wall, and the peripheral edge of the fixing hole is sandwiched between the locking claw and the base, it is configured to be attached to the wall. The shaft can be supported and fixed to the wall by a very simple operation. That is, when the bearing protrusion is inserted into the fixing hole of the wall, the elastically deformable locking claw protruding from the outer peripheral surface of the bearing protrusion comes into contact with the inner peripheral surface of the fixing hole. By pressing the portion in the direction of insertion into the fixing hole, the locking claw is pressed on the inner peripheral surface of the fixing hole and elastically deformed inward, and the tip of the locking claw reaches the opposite side of the fixing hole. Then, the locking claw elastically returns to its original state, and its tip engages with the peripheral edge opposite to the fixing hole, and the fixing hole peripheral edge is sandwiched between the locking claw and the plate-like base. Thus, the bearing member of the present invention is fixed to the wall. Therefore, the bearing member of the present invention can be reliably fixed to the wall by simply inserting the bearing protrusion into the fixing hole of the wall and pressing the same, and the conventional bearing shown in FIG. The support and fixing operation of the shaft body can be performed by an extremely simple operation without requiring a complicated operation such as screwing as in the case of the member e.
[0016]
In addition, by attaching a rotation control member having a pinion gear to one surface side of the plate-shaped base of the bearing member of the present invention so as to be juxtaposed with the bearing projection, the rotation control can be performed simultaneously with the mounting of the shaft body. The member can be set on the wall, and the work of mounting the rotation control member can be performed extremely efficiently.
[0017]
For example, a damper having a pinion gear as a rotation control member is attached to one surface side of the plate-shaped base of the bearing member of the present invention in parallel with the bearing projection, and the bearing body of the bearing member is subjected to the procedure described above. When supporting and fixing the damper to the wall, the pinion gear of the damper is meshed with the rack gear provided on the rotating body through the through hole provided in the wall, so that the damper is fixed to the wall at the same time as the support and fixing of the shaft. It can be set, and the assembling operation can be easily performed without requiring a special operation step even when the rotational movement of the rotating body is controlled using the damper.
