Description

[Detailed Description of the Invention] The present invention relates to a lid latching device for a battery storage device such as a communication device using a battery such as a radio receiver or a magnetic recorder.

In recent years, with regard to batteries stored in the cabinets of devices used, devices that allow the batteries to be taken in and out by opening and closing the back panel, for example, are often used. As seen in Publication No. 32885 or Figures 1 and 2, a locking piece is provided integrally with the cabinet or lid body molded from synthetic resin, and the elasticity of the synthetic resin is utilized to engage the locking piece. It has stopped.

In the former case, the lid is formed at a corner of the cabinet, and the lid is opened and closed using this as a cue.

In addition, when the lid body 1 is formed on a flat surface of the cabinet 2 as in the latter case, the tip 31 of the spring-like locking piece 3 having a U-shaped cross section is attached to the top of the cabinet 2 as shown in the second side sectional view. It protrudes above the surface, and the side wall serves as a surface for opening the lid.

However, with this type of structure, when the cabinet is being transported, an accident has occurred in which the tip 31 of the spring-like locking piece 3 gets caught on a frequently used item, causing the lid 1 to become unlocked and fall off.

This means that in order to make sure that the finger can be gripped more securely, it is necessary to make the tip 31 protrude relatively far above the surface of the cabinet, and in order to prevent such accidents from falling off, conversely, this protrusion should be made as small as possible. I needed to.

These conflicting requirements arise from the fact that the locking position of the lid 1 and the surface of the finger rest on the tip 31 are in the same position, and from the viewpoint of obtaining a reliable finger catch, the height of the tip 31 should be lowered. I couldn't do it.

This proposal was made in view of this point, and the finger hook used when opening the lid is separated from the surface and the locking piece used when closing the battery storage hole with the lid. The present invention relates to a lid latching device for a battery storage device in which the tip of a spring-like locking piece forming a surface of the finger hook is formed lower than the cabinet surface by utilizing the spacing.

The present invention will be explained below with reference to the drawings of the embodiments, and for convenience, the same or equivalent parts in each drawing are given the same reference numerals.

FIG. 3 shows a partially cutaway perspective view of the lid attachment device of the present invention,
FIG. 4 is a partial plan view showing a state in which this is attached to the cabinet 2, and FIG. 5 is a sectional view taken along the line BB' in FIG.

As shown in each figure, in the present device, the spring-like locking piece 3 is attached to the lid body 1.
It extends downward from a position somewhat recessed from the end 11, and its tip 31 is bent and stands up from the end 11 at a predetermined distance sufficient for fingering.

Therefore, this spring-like locking piece 3 is formed to have a U-shaped cross section like the conventional one, but its tip 31 is formed on the same horizontal plane as the cabinet 2 or lower than it as appropriate, as shown in the fifth sectional view. There is.

The spring-like locking piece 3 is provided horizontally from a position where the side wall extending downward from its tip forms a sufficient length as a finger rest surface.

The locking piece 33 has a tapered tip so that its tip 34 engages with the inner surface 22 of the lower end of the opening edge of the battery storage hole 21 formed in the cabinet 2 and locks the lid 1 to the cabinet 2. is provided.

At this time, the tip 31 of the spring-like locking piece 3 is biased toward the cabinet 2 by its elasticity, so that the engagement between the tip 34 of the locking piece 33 and the inner side 22 of the lower end of the cabinet 2 is made to a suitable depth. In order to do this, stopper walls 35 and 36 are formed on both sides of the locking piece 33 in the vertical direction.

The tip 34 is formed by an outer surface 41 that hangs diagonally downward and a stepped surface 42 that extends in the horizontal direction.

Therefore, the vertical surface 40 of the stopper wall 35, 36 on the cabinet 2 side comes into contact with the opening end surface 43 of the battery storage hole 21 when the lid 1 is closed.

Therefore, when the lid body 1 is closed, the finger hook on the cabinet 2 side of the tip 31 of the spring-like locking piece 3 is adjusted to an appropriate depth as shown in FIG. A side chamber 37 is formed in the finger rest into which the finger is inserted.

As a result, the finger hook used when opening the lid body 1 is on surface 3.
2, and the tip 34 of the locking piece 33 used when closing the lid.
and will be provided at appropriate intervals.

As described above, the present device can cover the battery storage hole with the lid without causing the tip of the spring-like locking piece to protrude above the surface of the cabinet.

In addition, when opening the lid, the finger rest allows the finger to be inserted into the side chamber, and the finger rest presses the surface against the elasticity of the spring-like locking piece, thereby releasing the engagement at the tip of the locking piece. It is something that can be done.

Furthermore, the side chamber 37 can be formed at the same height as the open end surface 43 of the cabinet 2, and the finger rest can be made as high as possible to facilitate the finger rest.

Furthermore, when the lid body 1 and the spring-like locking piece 3 are integrally formed from synthetic resin, they can be constructed with a mold that is divided into both the outer surface and the inner surface of the lid body 1, and the mold can be made simple and inexpensive. .
