Description

[Detailed description of the invention] The present invention relates to a lid opening/closing device for a lidded container.

Examples of conventional lid opening/closing devices include those shown in FIGS. 1 to 4 (see FIG. 8 of Japanese Utility Model Publication No. 57-52342).

This device is attached to a car body or used in an ashtray with a lid, and is composed of a lid arm 2, a loop-shaped spring 3, and a spring guide 4. The above lid arm 2
The hinge pin 15 of the lid 1 is attached to the base of the lid 1, and the pin shaft portion 3a of the spring 3 is pin-coupled to the tip.

This spring 3 has one pin hoe portion 3b connected to the ashtray container 5.
The lid is supported on the side wall 5a of the lid, and its repulsive force can close the lid and urge the contact layer as shown in FIGS. 3 and 4. The spring guide is fixed to the rear wall 5b of the ashtray container 5, and its arc-shaped guide slit 6 guides the pin shaft portion 3a of the spring 3, and at the same time, the upper end of the slit 6 receives the pin shaft portion 3a. The stopper portion 6a functions as a stopper portion 6a for regulating the degree of movement of the lid 1. Note that 7 is a recess into which a finger is inserted when opening the lid. With this configuration, as shown in Fig. 3, when the lid 1 is in the closed position, the spring 3 is attached to the lid arm 2, and therefore the lid is moved to the arrow A with the hinge pin 15 in the middle. It is used in the direction of rotation.

Therefore, the lid 1 cannot be opened unless force is applied. When the lid is opened by inserting a finger into the recess 7, the spring 3 is guided by the guide IJ butt 6 of the spring guide 4, and when the spring 3 comes to the line connecting the hinge pin 15 and the pin whip 3b, Maximum compression. Then, at the same time as the pin shaft portion 3a passes over the above line, the lid 1 opens due to the anti-trailing force of the spring 3, as shown in FIG.
It hits a and stops. However, in such a conventional lid opening/closing device, the spring 3 that biases the lid 1 to the open or closed position and the pin shaft portion 3 of the spring 3 are
Since the container is constructed by assembling two parts, the spring guide mother which guides the a and regulates the relationship between the lid and the lid, there is a problem that the number of assembly steps is large and the cost is high.

In addition, when the pin shaft portion 3a of the spring 3 slides through the guide slit 6 of the spring guide 4, it may get caught and not move smoothly, and there is also the problem that it makes an abnormal noise. Depending on the mounting state of the spring guide 4, the volume of the container may be used.
This invention was made by focusing on the conventional problem 1, ``Springs and spring guides in secondary lid opening/closing devices!Instead, ~ by hanging on the hook of the container, the relationship between the lids can be adjusted. By using a curved spring integrally formed with a regulating rod-shaped hook, the aim is to solve the problem of ``Kamitakuma''.

Hereinafter, this invention will be explained based on the drawings.

5 to 8 (the same parts as in FIGS.

) is a diagram showing a practical example of the present invention. First, to explain the structure, 81 is a curved spring, the pin shaft part 8a at one end is pin-coupled to the tip of the lid arm 2, and the pin shaft part 8b at the end is supported by the side wall 5a of the ashtray container 5. .

This curved spring 8 rotates the lid arm 2 around the hinge pin turtle 5 by its repulsion force, and as shown in FIGS. 9 is the curved spring 8
It is integrally formed on the pin shaft portion 8a.

The rod-shaped hook is a hook hook on which a rod-shaped hook 9 is hung, and is provided on the side wall 5a of the ashtray container 5. When the lid 1 is opened, the rod-shaped hook 9 is caught on the hook hook 10 and the curved spring
This is to regulate the opening of the lid 1 by 1 to a certain degree. Next, the effect will be explained. As shown in Fig. 6, when the lid turtle is in the closed position, the bending spring 8 rotates the lid arm 2 in the direction of arrow B around the hinge pin 15, so that the lid turtle is biased in both directions. Ru.

For this reason, Lid 1 cannot be opened unless you apply force. To open the lid, insert your finger into the recess and push it up in the direction of arrow C.

Is the pin shaft part lotus a of the curved spring 8 exactly the 1st? As shown in the figure, when the curved spring 8 comes on the line connecting the hinge pin 1 and the pin shaft part 8b, the curved spring 8 is compressed to the maximum. It opens with the rebuttal force of 8.At this time, the rod-shaped hook g
is hooked by the hook hook 01 to regulate the opening of the lid to a preset opening degree. In the above embodiment, the rod-shaped hook 9 was integrally formed with the pin tangerine, but it may be directly integrally formed with the curved portion of the curved spring 8. As explained above, the lid opening/closing device of the present invention replaces the spring and spring guide in the conventional lid opening/closing device, and uses a rod-shaped hook that is hung on a hook provided on a container to regulate the relationship of the lid. Since the machine is constructed by assembling a curved spring that is integrally formed, the conventional spring guide is no longer required, and the number of man-hours required for paper installation is reduced, reducing costs.At the same time, the spring guide is no longer necessary. This eliminates functional problems such as the pin shaft of the spring getting caught in the guide slit, which causes abnormal noises, as in the past.

Furthermore, since the spring guide is no longer required, the space of the container can be used more widely.
