Description

BACKGROUND OF THE INVENTION

The present invention relates to a cartridge for compact discs and in particular to the present invention relates to a CD-ROM cartridge having a disc holder for receiving individual CD-ROMs rotatably mounted on a bearing pin and rotatable in or out of the cartridge.

BACKGROUND OF THE INVENTION

Various storage cartridges for storing compact discs, laser disks, CD-ROMs, etc. are described and these cartridges appear on the market. Giant. ΙΑ, 1B and IC show various CD-ROM cartridges of the prior art. These CD-ROM cartridges 10 typically have a lower case 12 carrying an individual CD-ROM, a cover case 11 having two opposing side walls 111 and 112 rotatably connected to the lower case 12 on both sides, and a compact disc holder 13 in the lower case 12 in the middle. The lower case 12 has two opposite side notches 121 and 122 for inserting fingers when inserting or removing a CD-ROM. These types of CD-ROM cartridge cases have the same disadvantages. When the housing 11 is facing the housing 12, the two opposite facing walls 111 and 112 of the housing 11 may be easily detached from their respective rotatable parts on the housing 12. Further, when inserting or removing a CD-ROM, the CD-ROMs may deform or damage. The CD-ROMs may also fall out when the CD holder 13 is released or in the released position.

SUMMARY OF THE INVENTION

The present invention has been practiced in the above circumstances.

According to one embodiment of the present invention, the compact disc storage case comprises a flat housing body having an edge opening on one side and a bearing pin close to the inside thereof, and a CD-ROM mounting disc holder rotatably mounted on the bearing pin and rotating in or out. from the cartridge, the disc holder having a spring head in the middle to the front

DETAILED DESCRIPTION OF THE INVENTION

Referring to Figs. 2 and 3, a compact disc cartridge housing according to an embodiment of the present invention generally consists of a flat housing body 40 and a compact disc holder 50. The housing body 40 consists of a rectangular front cover 41 having two pin holes 413 in its four. corners and a rectangular rear cover 42 having opposing pins 423 in its four corners which are inserted into their respective pin holes 413 on the front cover 41. This method of assembling the front and rear

9382 rear cover is only an example, but not a limitation. The front 41 and the rear cover 42 define on one side their respective aperture 411 or 421, which allows the CD holder 50 to pivot in or out of the housing body 40 ♦ The rear cover 42 has a tube-shaped bearing pin 43 and a retaining groove 422 in opposite positions near the aperture 421 for mounting and positioning the CD holder 50. The CD holder 50 has a flat circular shape so that it can be inserted into the housing body 40 through the apertures 411 and 421.

Referring to FIG. 3A and again FIG. 3, the CD holder 50 has a pivot hole 51 in one corner that accommodates a tube-shaped bearing pin 43 and a spring head 52 (not shown) in the middle for accommodating a CD-ROM, two parallel ribs 55 spaced apart from each other on the back and defining a space for storing sheets of paper, a small retaining raised edge (flange) 54 opposite the pivot hole 51 that engages in the retaining groove 422 on the rear cover 42 when the holder is compact the discs 50 inside the housing body 40, an elongated stop plate 53 that pauses on the front 41 and the rear cover 42 outside the holes 411 and 421 when the compact disc holder 50 is rotated into the housing body 40, a direction arrow sign 531 at one end of the stop plate 533 , a finger hole 532 on the stop plate 53 in a suitable position and at least one piece 533 provided with a recess on the stop plate 53 for sticking labels and the like. Further, the exterior of the body of the housing 40 may be covered with advertising paper or packaging for advertising.

Referring to Figs. 4, 4A and 4B, the compact disc holder 50, when assembled, is mounted on the bearing pin 43 and rotated in and out of the housing body 40. When the compact disc holder 50 is rotated inside the housing body 40, a small retaining raised edge ( the flange 54 is engaged in the retaining groove 422 and thereby the CD holder 50 is retained within the housing body 40. However, the CD holder 50 may still be conveniently pivoted out of the housing body 40 by pulling the top end (location of the direction arrow sign 531) of the stop plate 53 out of the housing body 40 (see FIG. 4A). When the CD holder 50 is pivoted out of the housing body 40. the lower end of the stop plate 53 stops one side of the housing body 40 thereby preventing the CD holder 50 from rotating further and therefore the bearing journal will not be damaged (see FIG. 4B). When the bracket is

9382 compact discs 50 pivoted from the housing body 4.0, the CD-ROM 60 can be removed from the compact disc holder 50 by inserting a thumb into the finger hole 532 and pressing the other four fingers onto the outer edge of the CD-ROM 60, then pulling the CD-ROM 60 out CD heads 52 of the CD holder 50. A sheet of paper bearing the words of the songs may be inserted at a designated location on the back of the CD holder 50 between the ribs 55.

Referring to Fig. 5, the body size of the housing 40 may be increased relative to the compact disc holder 50 to accommodate a plurality of compact disc holders 50. In this arrangement, the lost head metal connecting rod 44 and the threaded rear portion is transverse mounted and a plurality of respective holes (not shown) on the CD holder 50 so that the CD holder 50 can be rotated in and out of the cartridge body 40.

While only two embodiments of the present invention have been shown and described, it should be understood that various modifications may be made without departing from the nature and scope of the present invention. For example, the aforementioned bearing pins 43 and retaining grooves 422 may be on the front cover 41.
