It is characterized in that an engaging projection for engaging is formed.

[0009]

[Embodiment of the invention]

 Hereinafter, the present invention will be described in detail based on an embodiment shown in the drawings. FIGS. 1 to 4 are views showing an embodiment of a simple CD ejector according to the present invention, in which reference numeral 1 denotes a simple ejector.

The simple CD ejector 1 has a columnar ejector main body 2, a pressing portion 3 formed on the upper portion of the ejector main body 2, and a cross-shaped pressing portion formed on the bottom of the ejector main body 2. On the three sides, four legs 4 having a predetermined radius of curvature R are provided. The number of the legs 4 may be two or more. Further, the extraction tool main body 2 and the leg 4 are integrally formed of resin, but the pressing portion 3 is formed of resin separately from the extraction tool main body 2 and then fitted to the extraction tool main body 2 and assembled.

As shown in FIG. 2, the pressing portion 3 includes a disk 3a and a fitting portion 3b formed on the lower surface of the disk 3a. The upper surface of the disk 3a can be pressed by a finger, and The lower surface is formed in a thin plate shape so as to be in close contact with the upper end of the fitting cylinder 12. The fitting portion 3b is formed in a cylindrical shape having an outer diameter smaller than the outer diameter of the removal tool main body 2, is integrally formed on the lower surface of the disk 3a, and is returned by forming an engaging projection 3c at the tip. Is composed.

On the other hand, a through-hole 2 a is formed along the axis inside the removal tool main body 2, and the lower end of the through-hole 2 a is slightly enlarged to engage with the engagement protrusion 3 c of the pressing portion 3. A mating recess 2b is formed. Then, when assembling the pressing part 3 and the removal tool main body 2, the fitting part 3 b of the pressing part 3 is pushed into the through hole 2 b of the removal tool main body 2, so that the engagement projection 3 c at the tip is engaged with the engagement recess 2 b. , The pressing portion 3 and the removal tool main body 2 can be integrated so as not to come off.

Next, in order to attach the simple CD ejector 1 in which the pressing portion 3 and the ejector main body 2 are integrated to the fitting tube 12 on which the CD 10 is mounted, an arbitrary shape formed on the fitting tube 12 is required. After the leg 4 is aligned with the dividing groove 13, the removal tool main body 2 is fitted into a circular space 14 formed in the center of the fitting cylinder 12, and a state as shown in FIG. 3 is obtained. At this time, it is preferable to push in such that the back surface of the disk 3 a of the pressing portion 3 is in close contact with the upper surface of the fitting tube 12.

Next, a method of taking out the CD 10 from the fitting tube 12 using the simple CD removal tool 1 will be described. As shown in FIG. 4, the pressing portion 3 is pressed downward by a finger to crush the fitting tube 12. When pressurized in such a state, the back surface of the pressing portion 3 formed in a slightly concave curved surface comes into contact with the inner edge of the circular space portion 14, so that the fitting cylinder 12 falls down inward to reduce the diameter. The fitting between the outer periphery of the cylinder 12 and the CD 10 is released.

At the same time, the CD ejector 1 moves downward by pressing, so that the leg 4 is elastically deformed upward with the inner peripheral end face 15 of the division groove 13 as a fulcrum, and lifts the CD 10. Therefore, only by pressing the pressing portion 3 downward with a finger, the CD 10 floats up from the fitting tube 12 and jumps out to the upper portion of the fitting tube 12, and the outer periphery of the CD 10 is moved with one hand or finger. It can be easily taken out just by pinching it.

In this case, since the intermediate portion of the leg 4 is supported by the inner peripheral end surface 15 of the dividing groove 13 and the tip of the leg 4 lifts the back surface of the CD 10 by the leverage principle, the pressing portion 3 is only lightly pressed. Thus, the CD 10 can be reliably lifted.

The width of the dividing groove 13 formed in the fitting tube 12 decreases at the inner edge of the circular space portion 14 and comes into contact with the R formed in the leg portion 4. Play can be reduced, and the fingertip can be prevented from adhering to the pressing portion 3 due to sweat or the like to lift the CD simple removal tool 1 together with the CD 10, thereby improving the strength when the leg portion 4 is elastically deformed. be able to.

Further, after the pressing portion 3 and the ejection device main body 2 are separately molded by an injection molding machine or the like, the CD simple ejection device 1 is integrated by fitting these pressing portions 3 to the ejection device main body 2. Therefore, the assembling is simple, the formwork at the time of molding is simplified, and mass production is possible.

[0019]

[Effect of the invention]

 As described above, the simple CD ejector of the present invention has a columnar ejector main body mounted in the circular space of the fitting tube, and is formed integrally with the bottom of the extractor main body. Since it has a leg portion arranged inside the dividing groove and a pressing portion provided on the upper part of the extraction tool body and arranged to cover the upper surface of the fitting tube, the pressing portion can be pressed lightly. A CD can be easily and reliably taken out. In addition, since the pressing portion is fitted to the main body of the extraction tool and assembled, the production and assembly are simple, and mass production is possible.

According to the second aspect of the present invention, since R having a predetermined radius of curvature is formed at a connection portion between the extraction tool main body and the leg, the R reduces the play of the extraction tool main body in the vertical direction and reduces the CD. It is difficult to come off the case, and the strength of the legs can be improved.
