Description

[Detailed explanation of the invention] (a) Industrial application field This invention is a tape recorder cassette cover body,
This invention relates to a locking device for a disk lid of a CD player.

(B) Prior Art Various configurations have been proposed for locking devices for lids, and one of the most common is the configuration described in Japanese Utility Model Publication No. 54-38192. .

(c) Problems to be solved by the invention In recent years, tape recorders have become increasingly smaller due to their portability, so in particular, a configuration that locks the opening/closing state of the lid and a configuration that releases the lock to open the lid are required. cannot take up a large space.

According to the conventional structure as described above, the space required for the locking structure of the lid and the structure for releasing the lock becomes large.

(d) Means for solving the problems In view of the above-mentioned problems, the present invention has a rotating bearing part on a sliding lever that slides between a first position and a second position by operating a knob. and elastic ribs are integrally molded, and a locking member having a locking claw piece formed at one end is rotatably supported by the rotational bearing part and held in a fixed position by the elastic rib. It is attached to the sliding lever, the first position of the sliding lever is a position facing the locking claw piece of the locking member and the locked claw piece of the lid body, and the second position of the sliding lever
There is provided a locking device for a lid body, characterized in that the locking claw piece of the locking member and the locking claw piece of the lid body are arranged in a non-opposing position.

(E) Function When the sliding lever of the locking device of the present invention is in the first position, the locking claw piece of the locking member faces the locked claw piece of the lid body, so that when the lid body is closed, the locking member is rotated against the elastic force of the elastic rib due to the connection of the locking claw piece and the locking claw piece, and then returns to the normal position by the elastic force of the elastic rib, thereby locking the lid in the closed state. When the sliding lever slides from the first position to the second position, the locking claw piece of the locking member attached to the sliding lever is separated from the locked claw piece to the side, and the lid body It acts to release the lock.

(F) Embodiments Below, embodiments of the device of the present invention shown in the drawings will be described.

1A and 1B are a sectional side view of the main part of the lid just before it is closed, and a sectional side view of the main part with the lid closed;
It is composed of a front panel 2 having a cassette mounting part 2a and a space 2b for arranging a locking device to be described later, and a lower part 3 is pivotally supported by the front panel 2 so that it can be opened and closed with respect to the cassette mounting part 2a. It is a lid provided on the.

The lid 3 is provided at its open end with a locking pawl 4 associated with a locking device.

Reference numeral 5 denotes a sliding lever that is slidably provided along the cabinet top plate 1 in the space 2b and slides between a first position and a second position, and as shown in FIG. 5a and elastic ribs 5b, 5b are integrally molded. Reference numeral 6 denotes a lock claw piece 6b having shafts 6a, 6a rotatably supported by the rotation bearing portion 5a of the sliding lever 5 formed at the other end, and joined to the locking claw piece 4 of the lid body 3 at one end. As shown in FIG.
It is held in place.

4A and 4B are cross-sectional views showing the first and second positions of the sliding lever 5, in which the sliding lever 5 disposed in the empty space 2b is connected to a transparent plate formed on the cabinet top plate 1. It is slid along the cabinet top plate 1 through the hole 1a by a knob 7 that is operated from left to right in the figure. When the sliding lever 5 is in the first position, the locking claw piece 6b of the locking member 6 held by the sliding lever 5 touches the locked claw piece 4 of the lid body 3.
When the sliding lever 5 slides from the first position to the second position, the locking claw piece 6b of the locking member 6 moves to a position not facing the locked claw piece 4 of the lid body 3. do.

Therefore, when the slide lever 5 is slid to the first position by operating the knob 7, the lock pawl piece 6b of the lock member 6 is in the position shown in FIG.
As shown in Figure A, when the lid body 3 is closed, the locking pawl piece 4 joins with the locking pawl piece 6b, and the locking member 6 is rotated against the elastic force of the elastic ribs 5b, 5b.
Then, the locking claw piece 6b returns to its regular position by the elastic force of the elastic rib, thereby locking the locked claw piece 4 and locking the lid body 3 in the closed state as shown in FIG. 1B. I can do it.

When the knob 7 is operated from such a closed state to slide the slide lever 5 to the second position as shown in FIG. 4B, the lock member 6 will also move together.
The locking pawl piece 6b is laterally separated from the locking pawl piece 4. At this time, the locking member 6 does not rotate against the elastic force of the elastic ribs 5b, but simply escapes to the side while remaining in the fixed position.

Therefore, the lid 3 is unlocked and can be opened.

(g) Effects of the invention As described above, the present invention enables the lid to be locked by rotating the locking member when the sliding lever that slides between two different positions is in the first position, and the sliding lever slides into two different positions. When the lid is slid to the second position, the locking member is moved laterally to unlock the lid, so when the locking pawl is provided at the open end of the lid, the locking member is moved to the side and the lid is locked. A sliding lever can be disposed to be slidable left and right along the cabinet, and the sliding lever can be controlled by a knob that is operated left and right on the cabinet top plate. Therefore, the locking device can be disposed in a small space between the open end of the lid and the cabinet top plate, making it useful for small-sized devices such as tape recorders that require a small space.
