Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a device for quickly and easily ejecting a compact disc (CD) from its case.

(Prior Art) In a conventional compact disc case, a slight space S is provided between the case body 1 and the bottom wall 1a, and slits 4 are formed at predetermined angular intervals in the centripetal direction. 7 has a disk hole press-fitting circular projection 2 composed of a group of elastic diaphragm pieces 3 bent and formed in a stepped shape, and the disk fitted in the circular projection 2 is to be removed for use as shown in FIG. Support the case body 1 with one hand, spread the other hand as much as possible, hold the disc edge on the front side with the tip of the thumb, and the disc edge on the opposite side with the tip of the middle finger. It is picked up against the pressure of the protrusion 2 (the repulsive force acting in the centrifugal direction of the elastic diaphragm pieces 3 by pressing the disk hole 10 into the circular protrusion 2).

However, this work has the trouble of having to fully extend the hands first, and it is a great pain for people with small hands, and the pressure on the circular protrusion 2 is unexpectedly large, so it is not possible to perform the pulling operation once. It is difficult to extract, and the disk itself is distorted many times, resulting in long-term metal fatigue.

As a means for assisting the above operation, the upper surface of the circular protrusion 2 is pressed by the tip of the index finger to squeeze the elastic diaphragm pieces 3 inward (that is, the repulsive force acting in the centrifugal direction is weakened).
In combination with the above operation, it is sometimes taken out,
In this case, the fingertip directly penetrates into the elastic diaphragm piece group 3 provided with the slit 4, which not only causes discomfort but also averages the pressing force. Further, depending on how to apply the fingertip,
On the contrary, the fingertip may adversely affect the floating of the disc (in order to remove the disc smoothly, the fingertip applied to the circular protrusion 2 must be inserted through the sunnary and the disc hole).

(Problems to be solved by the invention) The present invention has been made in view of the above-mentioned actual circumstances,
The elastic projection piece 3 is attached to the circular projection 2 composed of a group of elastic diaphragm pieces 3 at the center, regardless of the means for fully enclosing and pinching the hand.
By providing means that can be pressed in a separated state from the group, the disc can be removed quickly and easily by the linking operation of the index or middle finger and the thumb.

[Structure of the Invention] (Embodiment) Referring to an embodiment of the drawing, in FIG. 1, reference numeral 1 is a case body of a compact disc, and 9 is a lid thereof.

A disc space press-fitted with a group of elastic diaphragm pieces 3 formed by bending stepwise with a slight space S between the bottom wall 1a and the center wall of the case body 1 and slits 4 at predetermined angular intervals in the centripetal direction. A circular protrusion 2 is provided (the configuration up to this point is the same as in the conventional technique).

As shown in FIGS. 1 to 3, the circular protrusion 2
In the central hole 2a of the elastic throttle piece 3, the circular guide plate 7 slightly larger than the inner edge peripheral portion 3a of the elastic diaphragm piece 3 is attached to the head, and the stopper 8 is attached to the bottom. The pushing plate 7 is inserted in a state of being suspended from the upper surface of the inner edge peripheral portion 3a of the group of elastic diaphragm pieces 3 to form the extracting device of the present invention.

(Operation) When a vertical force is applied to the circular pressing plate 7 as shown in FIG. 4 from the state shown in FIG. 3 in which the disk is press-fitted into the circular protruding portion 2, the circular pressing plate 7 is elastically deformed. As a result of being formed slightly larger than the inner edge peripheral portion 3a of the group of diaphragm pieces 3,
The inner edge peripheral portion 3a is squeezed downward inward.

Therefore, as shown in FIGS. 5 and 6, by pressing the circular pressing plate 7 from the vertical direction with the index finger or the middle finger, the disk hole 10 is released from the press-fitted state by the press-fitted circular protrusion 2. As shown in the figure, hang your thumb on the edge of the disc and pull it inward to push it inwardly.
The fingertip that has previously come into contact with the circular pressing plate 7 is smoothly inserted into the floated disc hole, and the disc can be removed without difficulty.

When the finger pressing the circular pressing plate 7 is released, the elastic diaphragm pieces 3 are elastically restored to the state shown in FIG.

The circular push plate 7 is acted by the stopper 8 fixed to the bottom of the guide short shaft 6 to which the circular push plate 7 is fixed.
There is no getting out.

[Effects of the Invention] As described above, the present invention allows the compact disc to be quickly and easily removed from the case with extremely natural hands and without applying unnecessary load to the desk itself (that is, soft touch). It is possible and very useful for CD lovers.

Since the manufacturing cost does not change the basic structure of the case body so far, it can be mass-produced at low cost.
