Description

[Detailed explanation of the idea] The present invention relates to an improvement of a lid holding structure.

There are various types of structures having lids, one of which is the battery box for electronic equipment shown in FIGS. 1 and 2. That is, this battery box 1 consists of a battery case 2 and a lid 3, and includes an upper plate 4 of a device housing 4.
The device is housed in the device casing 4 using the opening 5 formed at a. To hold the lid 3, one end of the hinge 6 is attached to the inside of one end of the lid 3, and the other end of the hinge 6 is attached to the outside surface of the battery case 2, and a countersunk screw 7 is inserted from inside the case 2. It has a structure in which the lid 3 is held using screws. Numeral 8 is a set screw that is screwed onto the case stopper plate 2a to lock the lid 3 when it is closed.

By the way, when the lid 3 is generally held using the hinge 6, the closed position of the lid 3 is completely dependent on the mounting position of the hinge 6. Therefore, when attaching the hinge 6 to the case 2, the mounting dimensions of the hinge 6 are required to be exact. However, in reality, it is extremely difficult to attach the hinge 6 to the case 2 with predetermined dimensional accuracy, and in many cases, some positional deviation is involved. If the mounting position of the hinge 6 is misaligned, it will be difficult to adjust the misalignment, and the end of the lid 3 on the set screw side will shift far from the specified position, causing the lid 3 to be locked to the stop plate 2a by the set screw 8. It becomes very difficult to do so. This means that it is difficult to attach the lid 3 unless it is done by a skilled person, and sometimes the battery case 2 may be considered a defective product if the hole position of the countersunk screw 7 is greatly misaligned. In addition, since the screwing direction of the countersunk screw 7 that attaches the hinge 6 is perpendicular to the opening surface of the housing, when screwing the hinge 6, it is necessary to insert a tool diagonally through the opening 5 or use a special tool. Since it is necessary to use tools, a desired number of tools are always required, and there is a drawback that the work efficiency of equipment assembly is significantly reduced.

The present invention was made to eliminate the above-mentioned drawbacks, and its purpose is to make it possible to hold the lid by the simple operation of inserting the lid into the casing, etc., without the need for screws or tools. Moreover, the present invention provides a lid holding structure that does not easily come off inadvertently in this held state.

Hereinafter, one embodiment of the present invention will be explained in Figures 3 to 5.
This will be explained with reference to the figures. Fig. 3 shows the main parts of the present invention, in which Fig. 3a shows the lid 11 side, Fig. 3b shows the box,
A part of the case, device housing, etc. 12 (hereinafter referred to as the holding body) side is shown, and Figure 4 shows a cross section of the housing to which this structure is applied, and Figure 5 shows ○A in Figure 4. It is an enlarged view. First, regarding the lid 11 side,
One end piece 13a of a hinge 13 is attached to the inside of one end of the lid 11 by adhesive means, and the other end piece 13b of the hinge 13 is formed with, for example, a rectangular engagement hole 14 parallel to the end face of the lid one end. It is. Holding body 12 that holds the other end piece 13b of this hinge 13
The main body 12 has an elastic holder 16 that is connected to form a part of the inner wall of the main body 12 and has a tongue portion 15 protruding outward, and further has a tongue portion 15 that is inserted from the outside for a predetermined distance. The holding body 1 has a
A guide portion 17 is formed on the outside of 2.
Further, this guide portion 17 is provided with a notch 18 in the same direction as the holder 16 in order to facilitate release of the lid 11. Note that the holding body 16 and the guide portion 17 are integrally molded with the holding body 12. The other end of the lid 11 is screwed to a stop plate 12a of the holding body 12 by a set screw 19, as shown in FIG.

Next, an example of holding the lid 11 on the holding body 12 will be described. First, the other end piece 13b of the hinge 13 attached to one end of the lid 11 is attached to the tongue piece 1 of the holding body 12.
5 and the guide portion 17 from the direction of the arrow shown in the figure. When inserting the hinge 13, the tip of the other end of the hinge 13b comes into contact with the tongue part 15 and moves forward, causing damage; however, if the other end of the hinge 13b is further pushed strongly in the direction shown in the figure, , the tongue piece 15 of the holding body 12 is elastically moved to the fifth position.
As shown by the two-dot chain line in the figure, it is bent inward of the holding body 12, whereby the other end piece 13b of the hinge moves forward along the inclination of the tongue piece part 15. When the other end of the hinge 13b advances to a predetermined position in this manner, the engagement hole 14 of the other end of the hinge 13b engages with the tongue portion 15, thereby ensuring that the lid 11 is held securely. If it is necessary to release the lid 11 after holding the lid, push it manually or with a stick in the direction of the arrow ○C shown in FIG. By pulling the holding body 16 toward you from inside the holding body 12, the holding body 12
The lid 11 can be easily removed.

Therefore, according to the above-mentioned lid holding structure, the lid 11 is held by engaging the engagement hole 14 of the other end piece 13b of the hinge with the tongue piece 15 of the holding body 13, so a screw is used. The lid 11 can be held without any trouble. If screws are unnecessary, there is no need for a skilled person to determine the screw mounting position, and there is no problem of displacement of the screw mounting position after the lid is held, which would prevent the lid from being judged as an unnecessary item. Moreover, since it is an insertion type, the lid 11 can be held with a very simple operation without requiring any tools.
Further, the tongue portion 15 and the like can be integrally molded with the holding body 12, and the structure can be realized with a simple structure and at low cost.

Furthermore, by forming the tongue piece on the outer surface side of the holding body 16, the engagement state between the tongue piece and the engagement hole on the lid body side will not come off even if pushed from the inside side of the holding body. It cannot be removed unless you push or pull it in the opposite direction. Therefore, when an item such as a battery is inserted into or removed from the holding body during use, even if the item collides with the holding body 16 and the holding body 16 is pushed outward from the holding body, the tongue piece The engagement state with the engagement hole will not come off. This makes it possible to reliably maintain the attached state of the lid.

Note that the present invention is not limited to the above embodiments. In the above embodiment, the guide portion 17 has a notch 1.
Although the notch 8 is provided, it is not necessarily necessary to provide the notch 18. Although the hinge 13 is used to hold the lid 11, for example, as shown in FIG.
1 and the held member 21 may be formed thin to enable rotation of the lid 11, and furthermore, an engagement hole 14 may be provided in the held member 21. In addition, the present invention can be modified and implemented in various ways without departing from the gist thereof.

As detailed above, according to the present invention, the lid can be held in the holding body without the need for screws or tools, and since it is a push-in type, the lid can be held by simple operations without requiring any skill. Moreover, this holding state can be maintained reliably by making it difficult to come off inadvertently, and a lid holding structure with high practical value can be provided.
