Description

[Detailed description of the invention] This invention is mainly used when a lid-like object is removably provided to cover a predetermined opening or cover a predetermined outer surface of an electrical equipment case. It's about structure.

Conventionally, such a lid-like object has been formed as a lid that covers an opening for inserting and removing a battery into a battery storage section, for example, in the bottom wall or rear wall of a case of an electrical device. In that case,
In order to prevent the lid from falling off, the lid is screwed to the case, or the case and the lid are coupled using engagement of elastic locking pieces. However, the screw-fastening method has the problem that opening and closing the lid is troublesome.
In devices that utilize the engagement of elastic locking pieces, a protrusion for releasing the lock is usually provided on the outer surface of the case. There is a lid. Its general structure is
As shown in FIGS. 1 and 2, a protrusion 3 that engages with the casing 2 is provided at one end of the lid 1, and an elastic locking piece 4 curved in a chevron shape is provided at the other end to lock the lid. A groove 5 that engages with the opening edge of the housing 2 is provided at the tip of the locking piece 4, and the tip of the locking piece 4 is formed into a convex portion 6 so that it can be easily operated with a finger. When opening the lid 1, the convex portion 5 is pressed and the lid 1 is moved slightly in the opening direction. This type of lid mounting structure has the advantage that anyone can easily open it with just their fingers, but depending on the application, the lid may be opened carelessly and damage the internal components of the device. There was a problem that caused the equipment to malfunction due to misalignment or misalignment.

For this reason, the present invention has developed a lid for equipment cases that can be reliably maintained in a closed state without using a screw-fastening structure, prevents accidental opening, and is easy to open and close. The purpose is to provide a material bonding structure.

The lid-like object coupling structure of this invention is provided in a case wall forming one plane at a distance inward from the outer edge of the plane, and has inner edges for engagement facing each other on both sides, or an opening or the above-mentioned opposing inner edges. an equipment case having a pair of engagement holes drilled to form a corresponding edge corresponding to a predetermined engagement inner edge of the inner edge;
a lid-like object formed to cover the opening or the outer surface of the case wall including the space between the pair of engagement holes, and the lid-like object is attached to cover the opening or the outer surface of the case wall; each has a protruding portion that protrudes from the lid-like object in the closed state and extends into the case through the inner side of each of the inner edges for engagement or the inner side of each of the corresponding edges, and further extends outward on opposite sides. A structure for coupling a lid-like object to an equipment case, comprising first and second engaging pieces that are connected to the inner side of the case wall, and wherein the first engaging piece is an elastic engaging piece. A push rod insertion hole is bored in the case wall forming the one plane at a position outwardly away from the inner engaging edge or the equivalent edge that the first engaging piece engages, and This structure is characterized in that the first engaging piece is extended into the case so that the engagement can be released by pressing the first engaging piece with the tip of the push rod inserted from the push rod insertion hole.

According to this configuration, when the lid-like object is removed from the state where it is coupled to the device case, an appropriate rod-like object is inserted into the push rod insertion hole and the first engagement piece is pushed from the inside of the case. The engagement is released and the lid-like object is removed from the device case. When attaching the lid to the case, the second locking piece is first engaged, and then the first engaging side is pushed into the case.

Therefore, in this state of the device, it cannot be opened easily with just your hands or fingers, and to prevent the lid from being opened carelessly, it is necessary to make sure that there are electrical parts and adjustment parts inside the lid. It can be used for various purposes to reliably protect it from damage or distortion. Furthermore, since the coupling structure of this lid-like object is relatively strong, it can be used as a wall-hanging device when electrical equipment such as a portable radio or a desk telephone is to be hung on the wall. That is, it is sufficient to first attach the lid-like object to the wall surface and then connect the electrical equipment side to the lid-like object. When used as a wall fitting in this manner, the opening or engagement hole is provided at a distance further inward than the outer edge of the case wall, so the outer edge of the lid-like object can be positioned inward than the outer edge of the case. As a result, the lid is hidden behind the back of the device and is almost invisible, so that the device can be hung on the wall so that the design of the device is not impaired by the use of the wall hanging device (lid). be able to.

Examples of this invention will be described below. 3 to 5 show the first embodiment, 10 is an equipment case, 11 is a lid, 12 is a first engagement piece, 13 is a second engagement piece, and 14 is a push rod insertion hole. It is.

The first engagement piece 12 extends from the lid-like member 11 and enters the case 10 with its side surface in contact with the inner edge 22, and has a folded slope 25 and a protrusion 26 that engages with the inner surface of the case 10. have. This first engagement piece 12 is an elastic engagement piece, which is molded with plastic together with the lid-like member 11, and is provided with a notch 27 shown in FIG. 4 so that it can be easily bent elastically.

The second engagement piece 13 extends from the lid-like object 11, enters the case 10 with its side surface in contact with the inner edge 23, and is folded back at an angle slightly smaller than the right angle to form the case 10.
It has a protrusion 28 that engages with the inner surface of 0. The protrusion 28 and the protrusion 26 are directed outwardly in opposite directions.

The push rod insertion hole 14 is bored in the wall surface of the case 10 at a position outwardly away from the inner edge 22 that the first engagement piece 12 engages with.

In this structure for connecting the lid-like object 11 to the case 10, a push rod 29 (for example, a screwdriver or the like may be substituted) is inserted through the push rod insertion hole 14, and the first
When the slope 25 of the engagement piece 12 of the case 1 is pressed, the case 1
Since the slope 25 also receives a component force in the opening direction of the lid 11 when the engagement with the lid 11 is released, the lid 11 can be easily opened by simply pushing. Furthermore, when closing the lid-like object 11, first engage the second engagement piece 13 side, and then simply push in the first engagement piece 12 side, and the first engagement piece 12 will also be in the engaged state. becomes. In this example, since the lid-like object 11 is used as a wall hanging device, it is attached to the wall in advance using the screw holes 24.
