Description

[Detailed description of the invention] The present invention relates to a click motion mechanism for the lid of a container, etc., and more specifically, it is a mechanism for applying a click motion to the lid of a container, etc., and is completely closed when opened. This invention relates to a click motion mechanism for a lid that can maintain an open state and, conversely, maintain a completely closed state when closed.

Conventionally, the lid of containers etc. can be opened and closed via a hinge;
It is composed of a thin piece that is integrally formed with a container, etc. However, since such a hinge itself has elasticity, when the lid body is opened, it does not open fully, and when it is closed, it remains slightly open and does not close completely. Therefore, it is inconvenient to take the contents in and out, and a special closing mechanism such as a stopper is required to completely close the container.

The present invention was developed in view of the above, and its purpose is to make the lid perform a click motion action, so that when the lid is opened, it is fully opened and this state is maintained. It is an object of the present invention to provide a mechanism that can maintain a completely closed state by its own action without requiring any special mechanism when it is held and closed.

Hereinafter, the present invention will be described in more detail with reference to illustrated embodiments.

1 to 6 show a first embodiment of the present invention, which is applied to a connecting portion between a container and a lid.

In the figure, 1 is a container made of plastic, and 2 is a lid integrally formed with the container 1. A hinge 3 connects the container 1 and the lid 2, and is integrally molded therewith. Further, the hinge 3 has a thin portion 3a at the center, which serves as a pivot point for the lid body 2. Reference numeral 4 denotes a pressurizing section provided in parallel with the hinge 3. The pressurizing part 4 has one end 5a bendably connected to the tip of a support piece described later, and the other end 5b connected to the lid 2.
an elastic piece 5 having a V-shaped cross section and bendably connected to the elastic piece 5;
a support piece 6 extending from the container 1 and supporting the one end 5a of the elastic piece 5 with its tip 6a so as to be positioned obliquely above the thin wall portion 3a of the hinge 3 closer to the lid body 2; It is made up of. The degree of opening of the lid 2 can be adjusted by shifting the positions of the thin wall portion 3a of the hinge 3 and the one end portion 5a of the elastic piece 5. For example, in FIG. 4, the position of one end 5a of the elastic piece 5 is closer to the thin wall portion 3a of the hinge 3 than in the example shown in FIG. growing. That is, in FIG. 3, there is a line X connecting the thin part 3a of the hinge 3 and one end 5a of the elastic piece 5, and a line X connecting the thin part 3a of the lid body 2 to the line X.
If the angle with the line Y extending along the top surface is A ₁ , the opening degree of the lid 2 is 2×A _1. Therefore, in order to increase the opening degree of the lid 2, this angle A ₁ must be increased. It is done by doing. Although FIG. 5 shows a cross-sectional shape of the elastic piece 5 that is different from that in FIG. 3, the function is the same as that in FIG. 3, and detailed explanation will be omitted.

To explain the mode of operation of this embodiment, the state shown by the solid line in FIG. 3 is the state in which the lid body 2 is closed. If you try to open the lid 2 in this state, the other end 5b of the elastic piece 5 will originally try to rotate along a trajectory a, but the thin part 3a of the hinge 3, which is the fulcrum for the rotation of the lid 2, Since it is located diagonally below the one end 5a of the elastic piece 5 on the side of the container 1, it draws a trajectory b. For this reason, when the lid body 2 is lifted, the elastic piece 5 is forcibly bent gradually, and the angle α becomes smaller. The position where this state is the highest is the position indicated by the imaginary line A, and when the lid body 2 is further rotated and passed through this position A, the elastic piece 5 is immediately pushed outward by the restoring force. The lid body 2 is inverted toward the container 1 side, and this state is maintained. This state is indicated by a virtual line B.

As described above, in the present invention, the lid can be opened and closed using a click motion, so that it can maintain the completely open and closed states.

Further, FIGS. 7 to 10 show a second embodiment of the present invention, in which the present invention is implemented in the fixing part 7 and opening/closing part 8 of the lid body 2', and the cross-sectional shape of the elastic piece 5 is The second embodiment is the same as the first embodiment except that it is formed into a rectangular shape, so parts having the same functions are designated by the same reference numerals and detailed explanations will be omitted. In this embodiment, the V-shaped portion closer to the opening/closing portion 8 acts as a spring.

Since the present invention has the above-described structure and operation, the lid body can be opened and closed using a click motion, so that when it is opened, it maintains a completely open state, and when it is closed, it can be held with a stopper etc. A completely closed state can be maintained without requiring a special closing mechanism. Furthermore, since one end of the elastic piece supported by the distal end of the support piece is positioned above the thin part of the hinge, by shifting the position of the one end of the elastic piece, the degree of opening of the lid body can be adjusted appropriately. It can be adjusted to
