Description

[Detailed description of the invention] (Field of industrial application) The present invention is a disk locking structure for a compact disk tray, more specifically, a tray for storing disks in the shape of a plate in a jacket for a compact disk. The structure of the disk locking part has been improved to improve the function of attaching and detaching the disk and its durability.

(Prior Art) As shown in FIG. 1, the jacket for a compact disk currently in use is such that a compact disk 1 is inserted into a disk-shaped tray 2 for storing the disk, and a hole in the disk 1 is inserted into a tray 2 for storing the disk. After inserting the locking member 3 provided at the center of the tray 2 to lock the disk 1, the two covering pieces 5 and 6 connected to the covering piece 4 bonded to the back surface of the tray 2 are successively folded. It has a structure in which both the front and back sides of the tray 2 are wrapped and covered when folded.

As shown in FIGS. 6 and 7, the structure of the locking member 3 in this tray 2 has conventionally been an annular ring that surrounds a circular hole b provided in the center of the tray a and covers the peripheral part from above. A disk support part c is provided,
By carving a plurality of equally spaced grooves d, d... on the inner peripheral edge, a plurality of centripetal sections e, e... are formed, and each section e is bent upward into a hook shape. It is known to have a shape in which the respective tips are joined together to form an annular protrusion f, and then the circular hole b is closed with a covering piece g lining the tray a, and the whole is made of hard synthetic resin. .

When the disc D is mounted, this locking member stably holds the disc at the inner periphery of its center hole by the small protrusion h provided on the outer surface of the hook-shaped bent portion of each section e. , when removing it, put your finger on the edge of the disc and use your other finger to touch the protrusion f.
The purpose is to release the engagement by the small protrusion h by pressing and to facilitate removal.

(Problem to be solved by the invention) However, with this locking member, even if the projection f is pressed when the locking member is disengaged, the engagement of the small projection h is not sufficiently released, and Since the disc depends on the force of the fingertip, there is a disadvantage that the disc is bent and damaged, and each section e... constituting the protrusion f is supported only on the inner peripheral edge of the disc support part c, and Since this functions both to hold and release the disk, the shape of the protrusion f tends to deform due to temperature fluctuations and repeated use, and it tends to lose its elasticity, and even becomes brittle and breaks. There was a problem with durability.

The present invention is a disk locking structure for a compact disk tray that stably holds the disk when it is inserted, and also has excellent functionality that allows it to be removed smoothly without damaging the disk when it is removed. The purpose is to provide excellent durability without impairing functionality during use.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a disk-shaped locking member by penetrating a circular hole in the center of the tray and covering the circular hole on the upper surface of the outer periphery. In the compact disc tray provided, the locking structure is such that the locking member elastically supports the pressing body disposed on the axis of the circular hole at the lower part thereof, and each of the locking members is horizontal than the peripheral edge of the locking member. It has a plurality of support pieces disposed in a centripetal manner that protrudes in the direction and is bent upward in a hook shape, and the hook-shaped rising portion of each support piece constitutes a cylindrical disk locking portion. The gist of this is to make it more practical.

(Example) Next, details of the present invention will be explained based on the example shown in FIGS. 2 to 5.

In the figure, 10 is a compact disk tray, which includes compact disk 1 (fourth,
A circular recess 11 is provided for accommodating the recess (see Fig. 5), and the whole has a dish-like shape. Reference numerals 12 and 13 designate recesses provided at appropriate positions around the recess 11 for resting the fingertips on the periphery of the recess when the disk is removed, and the bottom surface thereof has a curved surface.
14 is a circular hole provided through the tray 10 at the center of the recess 11, and 15 is a recess 11 around the circular hole 14.
This is a locking member provided to cover the circular hole 14. A peripheral edge 16 of the locking member 15 is slightly raised from the bottom surface of the recess 11 to form an annular disk support portion. Reference numeral 17 denotes a pressing body provided on the central axis of the circular hole 14, which has a cylindrical shape, a disk shape, or a push button shape as shown in the figure. There are a plurality of supporting pieces 18 disposed centripetally between the peripheral edge 16 and the pressing body 17, and each supporting piece 18 projects horizontally from the peripheral edge 16 and then hooks upward. It is bent by the mold and continues to the outer lower part 19 of the pressing body 17, and elastically supports the pressing body 17. On the outer surface of the hook-shaped upright portion 20 of the support piece 18, there is a protrusion or small protrusion 21 provided as necessary. Between each of the supporting pieces 18..., there is a cantilever-shaped 1 or 2 which projects horizontally from the peripheral edge 16 and then bends upward into a hook shape and stops.
The above-mentioned free pieces 22 are disposed in a centripetal manner as a whole. Each of these support pieces 18...
The hook-shaped rising portions 20, 23 of the free pieces 22, . In addition,
24 is a covering piece bonded to the back surface of the tray 10.

Next, the operation of this embodiment when the compact disk is attached and detached will be explained. When inserting the compact disc 1 into the disc locking portion, the respective protruding portions 25, 26 of each supporting piece 18 and free piece 22 are slightly lowered, and the respective hook-shaped rising portions 20, 23 are also lowered accordingly. They are tilted in the centripetal direction, and after the disk 1 is installed, the disk 1 is stably supported from the inside of the hole by their respective restoring forces. When the pressing body 17 is pushed downward when removing the disk 1, since each support piece 18 is connected to the pressing body 17 and its lower part 19, these pieces are attracted to each other in the centripetal direction, and the hook-shaped rising portion 20 It will lean inward. As a result, the elastic force applied to the disk 1 is suppressed, and the disk 1 is held only by the free piece 22, and receives an upward force due to its restoring force. At this time, the protruding portion 25 of the supporting piece 18 from the peripheral edge 16 also descends as the pressure is applied, so the moment the finger is released from the pressing body 17, this portion also rises rapidly as the supporting piece 18 restores itself, due to its spring effect. Flip disk 1 upward.

In this embodiment, when the small protrusion 21 is provided on the outer surface of the hook-shaped rising portion 20 of each support piece 18, the disk 1 is inserted between the small protrusion 21 and the protruding portion 24 when the disk 1 is inserted. This has the effect of supporting the disk 1 more stably. Further, in this locking member, since the hook-shaped rising portion 19 inclines inward when the disk is removed as described above, there is no possibility that the small protrusion 21 will become an obstacle to the removal of the disk.

The locking member in the present invention may be molded integrally with the main body of the tray, or may be molded separately and then combined.Also, although the embodiment shows an even number of support pieces, it can also be used with three or more support pieces. Additions and modifications can be made to the above embodiments without departing from the gist of the present invention, such as an odd number of them, if any.

(Effects of the invention) According to the invention, by pressing the pressing body, the elastic force holding the compact disc can be suppressed and the disc can be taken out by the spring effect at the same time, making it possible to attach and detach with one hand. easy and
Furthermore, since it is held stably against external vibrations when mounted, it is particularly useful for use in vehicles.

The support piece that receives the pressing operation is integrated with the pressing body, so it will not be deformed or damaged due to repeated use or changes in temperature.
It has excellent durability.
