Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a rotating member support device in which a rotating member is pivotally connected to a main body via a support, and in particular, the support has spring properties. The present invention relates to a rotating member support device made of wire.

[Prior Art] Conventionally, a split pin has been used as a support for pivotally attaching a rotating member such as a cover to a main body.

For example, a plug cover 1 as a rotating member of a small motor generator shown in FIG. 6 covers an opening 3 of a cover main body 2 as a main body in a manner that can be opened and closed. When installing the plug, first, support holes 4, 4a that communicate with each other are bored in both the cover body 2 and the plug cover 1, and hairpin-shaped cotter pins 5 are installed in both support holes 4, 4a from the inside. A cover 1 was rotatably pivoted to a cover body 2.

In addition, at this time, the split pin 5 itself is inserted into the support holes 4, 4.
After inserting into a, the tip is bent to prevent it from falling out.

[Problems to be Solved by the Invention] However, since the split pins 5 according to the conventional example described above are required on the left and right sides, the number of parts increases. Furthermore, when assembling, the split pin 5 has to be held while being inserted into the support holes 4, 4a, and the tips of the pins have to be bent, making the work complicated.
Moreover, special jigs and tools were required.

In addition, as a prior art, as disclosed in Utility Model Application No. 59-52066, a protrusion is formed on the main body,
Some devices are designed to support a rotating member using this protrusion.

Furthermore, Japanese Utility Model Publication No. 38-15923 discloses a technique in which hanging members 3 are separately provided at both ends of a wire rod 4 having spring properties, and the rotating member B is pivotally supported on the main body part A by the hanging members 3. Disclosed.

However, in this prior art, the number of parts increases because the hooking member 3 is separately provided, and the stopper section 2 for receiving the hooking member 3 needs to be separately provided on the main body section A, making the structure even more complicated. There is a problem.

Moreover, in Utility Model Publication No. 55-34324, support 3
A technique is disclosed in which a stopper part 3a is formed on one side of the rotary member 1, and the rotating member 1 is attached to the main body part 2 without coming off by the stopper part 3a.

However, since the support body 3 disclosed in this prior art has rigidity, the support hole 2a on the main body part 2 side must be formed into a special shape, which increases the number of machining steps and the assembly. Not only is this complicated, but also play is likely to occur between the rotating member 1 and the support 3. In order to absorb this play, a support hole 1a formed in the support 3 and the rotating member 1 is required. The dimensional accuracy between the two must be strict, which increases the number of processing steps.

This invention was made in view of the above circumstances,
To provide a rotating member support device that can reliably pivotally attach a rotating member such as a cover to a main body with a single member, and that can easily perform this assembly work without using jigs or tools. The purpose is

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a rotating member support device in which a rotating member is pivotally attached to a main body via a support, in which the support is made of a wire rod having spring properties. The ends of the support are bent inward at an acute angle to form a hook, the tips of the hook are bent at a substantially right angle to form a stopper, and the ends of the support are formed at both ends of the support. The latching portion is fitted into a support hole formed in the main body portion and the rotating member, and the stopper portion of the support body is latched into the support hole.

[Function] In the above configuration, the assembly work is performed by first aligning the support hole formed in the main body with the support hole drilled in the rotating member, and then bending and forming holes at both ends of the support body into both support holes. Insert the hook. Since this support has a spring property as a whole, it is press-fitted into both of the support holes while maintaining elasticity, and the stopper formed at the tip of the hook prevents the support from falling off. Ru.

[Embodiments] Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.

1 to 5 relate to an embodiment of the present invention, in which FIG. 1 is a plan view of a support body, FIG. 2 is an exploded perspective view of a rotary member support device, and FIGS. 3 and 4 are support FIG. 5 is a front view illustrating the procedure for attaching the body, and FIG. 5 is a longitudinal sectional view showing a state in which the attachment is completed.

In these figures, reference numeral 11 denotes a support body, and this support body 11 is made of a wire rod having spring properties, and hook parts 11a bent inward at an acute angle are formed at both ends of this support body 11. ing. Furthermore, this support body 11 is formed with a stopper portion 11b. This stopper part 11b is the above-mentioned hook part 11a.
In the figure, the tip is bent outward at a substantially right angle.

On the other hand, reference numeral 2 is a cover main body as a main body. This cover body 2 has an opening 3 formed therein. Support holes 4a facing each other are bored on both sides of the inner surface of the opening 3.

Further, reference numeral 1 indicates a plug cover as a rotating member. This plug cover 1 is attached to the opening 3. A pair of brackets 1a are integrally formed on both sides of the back surface of the plug cover 1. This bracket 1a is provided with a support hole 4 that coincides with the support hole 4a of the cover body 2.

Hook portions 11a formed at both ends of the support body 11 are press-fitted into the support holes 4, 4a of the plug cover 1 and the cover body 2.

Next, a procedure for assembling the rotating member support device with the above configuration will be explained.

First, the support hole 4a formed in the opening 3 of the cover body 2 is aligned with the support hole 4 formed in the bracket 1a of the plug cover 1.

Next, the hook portion 11a formed at one end of the support body 11 is attached to the support holes 4, 4a on one side. Then, after further pressing the support body 11 to cause the stopper part 11b to engage the bracket 1a, the support body 11 is bent in an arch shape, and the engagement part 11a formed at the other end is inserted into the support hole on the other side. 4, 4a.

When the pressing force on the support 11 is released, the support 11 returns to its original state due to its own resiliency.
The other hook portion 11a is press-fitted into the support holes 4, 4a on the other side. Of course, the support body 11 may be bent at the time of attachment, and the hook portions 11a at both ends thereof may be simultaneously attached to the support holes 4, 4a on both sides.

Further, the hook portion 11a of the support body 11 is connected to the support hole 4,
Since it is press-fitted into the plug cover 4a in a bent state, it has elasticity and does not rattle when the plug cover 1 is rotated.

Moreover, since the stopper portion 11b of the support body 11 is hooked to the bracket 1a formed on the plug cover 1, the support body 11 will not fall off even if it moves in either the left or right direction after assembly.

[Effects of the Invention] As explained above, according to the present invention, the support member for pivotally connecting the rotating member to the main body portion is made of a wire material having spring properties, and therefore is inexpensive.

Further, inwardly bent hook portions are formed at both ends of the support body, and the hook portions are fitted into support holes formed in the main body portion and the rotating member. When the support body is bent to face the support hole, it can be easily attached due to its own elastic force. Therefore, there is no need for conventional jigs and tools, and the workability is good.

Furthermore, since the rotating member can be supported by one support body, the number of parts is reduced.

Further, a stopper part is formed on the support body, and this stopper part is hooked into the support hole, so that even if the support body moves to the left or right, it will not fall off, and the rotating member can be moved to the main body. will be reliably supported.

Further, since the above-mentioned hooking portion is formed by bending a wire rod having spring properties at an acute angle, it is always fitted into the support hole by its own elastic force. Therefore, rattling during rotation of the rotary member can be prevented without increasing manufacturing accuracy, and the rotation operation becomes smooth.
