Abstract

PURPOSE:To obtain a stable supporting state where attachment and detachment can be easily performed without any possibility of damage by forming a recessed part in which the edge of the fitting part enters when an elastic member is bent on a supporting part. CONSTITUTION:Since recessed parts 11 are formed on supporting parts 11, edges 22 of a fitting parts 21 enter into the recessed parts 11 when an elastic member 20 is bent in the direction of an arrow A. That is, the recessed part serves as escaping spaces of the edge 22. Accordingly, the elastic member 20 can be bent easily, and attached and detached easily. And the possibility that the fitting parts 21 are damaged is eliminated. moreover, since the top end corners (edges) on the supporting parts 10 are chamfered, the elastic material 20 can be bent even easier, so that the attachment/detachment of the elastic member 20 becomes possible.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support structure for elastic members. In particular, the present invention relates to a support structure for an elastic member that can be easily attached and detached, is not damaged, and can be stably supported.

[0002]

2. Description of the Related Art An example of a conventional elastic member support structure is shown in FIG.
Shown in.

In the figure, reference numeral 1 is a casing or frame of various devices, and inner surfaces 1a thereof are provided with supporting portions 2 facing each other.

Reference numeral 3 denotes an elastic member, which has a fitting portion 4 that fits in the support portion 2. When the support portion 2 has a pin shape and the fitting portion 4 has a cylindrical shape, the elastic member 3 is supported rotatably around the axis of the support portion 2.

To attach the elastic member 3 to the support portion 2,
The elastic member 3 can be attached by bending it in the direction of arrow A, and can be removed in the same manner.

[0006]

In the above-described conventional structure, when the elastic member 3 is bent for attachment / detachment, prying occurs between the support portion and the fitting portion 4, so that attachment / detachment is easy. In addition, there is a problem that the fitting portion 4 may be damaged.

In order to facilitate the attachment / detachment and to prevent the breakage, a dimensional difference may be provided between the outer dimension of the support portion 2 and the inner dimension of the fitting portion 4 so that they fit loosely. However, if so, there is a problem that the supporting state of the elastic member 3 becomes unstable. In particular, when the support portion 2 has a pin shape and the fitting portion 4 has a cylindrical shape, there is a problem in that the rotating operation of the elastic member 3 becomes unstable.

An object of the present invention is to solve the above problems, and to provide a support structure for an elastic member which can be easily attached and detached, is free from the risk of breakage, and can be stably supported.

[0009]

In order to achieve the above object, a support structure for an elastic member according to a first aspect of the present invention is a support member facing each other, and an elastic member having fitting portions that fit into these support members. In a support structure of an elastic member configured to fit the fitting portion to the support portion by bending the elastic member, an edge portion of the fitting portion enters when the elastic member is bent. A recess is formed in the support portion.

According to a second aspect of the present invention, there is provided the elastic member support structure according to the first aspect, wherein the support portion is formed in a pin shape and the fitting portion is formed in a cylindrical shape. By forming a recess in the support portion, the cross-sectional shape of the portion in which the recess is formed is orthogonal to the axial direction of the support portion and is D-shaped.

A support structure for an elastic member according to a third aspect is the support structure for an elastic member according to the first or second aspect, in which at least a side of the support portion having the recess is opposite to the side where the recess is formed. Is characterized by chamfering the tip corner portion.

[0012]

According to the elastic member support structure of claim 1,
Since the recess is formed in the support portion and the edge of the fitting portion enters the recess when the elastic member is bent, the elastic member can be easily bent. Therefore, the elastic member can be easily attached and detached, and the fitting portion is not damaged.

Further, when the elastic member is mounted, the fitting portion of the elastic member fits in the portion of the support portion where the recess is not formed, so that the elastic member is supported in a stable state.

According to the elastic member support structure of the second aspect, in the elastic member support structure of the first aspect, the support portion is formed in a pin shape and the fitting portion is formed in a cylindrical shape. Therefore, the elastic member can be rotated around the axis of the support portion. Further, since the cross section of the support section, which is orthogonal to the axial direction of the support section at the portion where the recess is formed, is D-shaped, a more stable rotation operation of the elastic member can be obtained.

According to the elastic member support structure of the third aspect, in the elastic member support structure of the first or second aspect, at least the side of the support portion having the recess formed with the recess is defined. Since the tip corner portion on the opposite side is chamfered, it becomes easier to bend the elastic member, and the elastic member can be attached and detached more easily.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a sectional view showing an embodiment of a support structure for an elastic member according to the present invention.

In the figure, reference numeral 1 denotes a casing or frame of various devices, the inner surface 1a of which is provided with supporting portions 10 facing each other.

Reference numeral 20 denotes an elastic member, which has a fitting portion 21 that fits in the support portion 10.

The support portion 10 is formed in a pin shape,
The fitting portion 21 of the elastic member is formed in a cylindrical shape. Therefore, the elastic member 20 is supported so as to be rotatable around the axis of the support portion 10.

A recess 11 is formed in the supporting portion 10, and the cross-sectional shape of the portion where the recess 11 is formed is orthogonal to the axial direction and is D-shaped as shown in FIG.

Further, the tip corner portion (edge portion) of the support portion 10 is chamfered. The chamfered portion is indicated by reference numeral 12.

According to such a supporting structure, the supporting portion 10
Since the recess 11 is formed in the recess 11, when the elastic member 20 is bent in the direction of arrow A as shown in FIG.
The edge 22 of No. 1 enters the recess 11. That is, recess 1
Reference numeral 1 is a clearance space for the edge portion 22. Therefore, the elastic member 20 can be easily bent, and the elastic member 20 can be easily attached and detached. Moreover, the fitting portion 21 is not damaged.

Further, since the tip corner portion (edge portion) of the support portion 10 is chamfered, the elastic member 20 is more easily bent, and the elastic member 20 can be attached and detached more easily.

As shown in FIG. 1, when the elastic member 20 is mounted, the fitting portion 21 surely fits in the portion of the support portion 10 where the recess 11 is not formed (circular portion in cross section). The elastic member 20 is supported in a stable state. In particular, when a force in the direction of arrow B is applied, the lower portion 23 of the fitting portion 21 acts so as to contact the lower portion 13 of the support portion 10, so that a strong support structure is obtained in the arrow B direction. . Further, the inner peripheral surface 24 of the fitting portion 21 is the entire circumference at the tip end portion of the support portion 10, and most of the arcuate peripheral surface 14 is formed even in the portion where the recess is formed.
Since the elastic member 20 is guided by (see FIG. 2), the elastic member 20 can be stably rotated.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications can be appropriately made within the scope of the present invention.

For example, the shape of the elastic member 20 may be a plate shape extending in the direction orthogonal to the paper surface in FIG. 1 or a rod shape. The shape is arbitrary as long as it can be bent as shown in FIG.

The shape of the supporting portion is not limited to the pin shape and may be a rectangular parallelepiped shape. It is only necessary to form a recess into which the edge of the fitting portion enters.

For example, the recess 11 shown in FIG. 1 can be formed below the support portion. In this case, the elastic member 30 becomes easy to bend also in the arrow B direction. Also, the recess 1
1 may be formed in a ring shape around the axis of the support portion.

Chamfering is not always necessary, and as can be seen especially from FIG. 3, chamfering on the side where the recess 11 is formed is not necessary.

[0031]

According to the present invention, the elastic member can be easily attached and detached, and there is no fear of damage, and a stable supporting state can be obtained.
