DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0013] With reference to FIGS. 1, 2, and 3, a CD holder in accordance with the present invention comprises a first housing (10), a second housing (20), a selecting device (30), a restitution device (40) and a locking device (50).

[0014] The first housing (10) adapts to partially receive CDs inside and has two side plates (13) and a top plate (110) integrally formed with the two side plates (13) to define a receiving chamber (A). An ear (11) protrudes from each side plate (13), and a pivot hole (111) is defined in each ear (11). A cushion (12) is attached inside the housing (10) between the ears (11) to cushion the CDs. An opening (14) is defined in the top plate (110) at a second end of the first housing (10), and an upper notch (15) is defined in an edge periphery near the opening (14). A flange (1 6) is inwardly formed on an inner periphery near the upper notch (15) of the first housing (10), and a triangular mortise (17) is defined in each side plate (13) of the first housing (10). Additionally, a hole (140) is defined in each side plate (13) near the triangular mortise (17).

[0015] The second housing (20) corresponds to the first housing (10) to form a compartment to receive the CDs. The second housing (20) has two connecting portions (21) formed on a first end and corresponds to the ear (11) of the first housing (10). A pivot pins (220) is formed on an inner face of each connecting portion (21) to correspond to the respective pivot hole (111) in the ears (11). A lower notch (23) is defined in an edge periphery of a second end of the second housing (20) and corresponds to the upper notch (15) when the CD holder is closed. A pair of guiding plates (24) extends from an inner side-face of the second end of the second housing (20), and multiple slots (25) are formed between the pair of guiding plates (24) to respectively hold individual CDs. Moreover, a support plate (27) protrudes from the inner side face below the lower notch (23).

[0016] The selecting device (30) is rotatably mounted inside the opening (14) of the first housing (10) and composed of a shaft (31) and a roller (34). The shaft (31) has two ends, and a triangular tenon (32) is formed on the face of each end to mate with the corresponding triangular mortises (17) in the first housing (10). Moreover, at least one bump (33) is formed on a periphery of the shaft (31). A channel (35) is axially defined through the roller (34) to rotatably mount the roller (34) around the shaft (31). Multiple axial detents (not numbered) are formed in the channel (35) to receive the at least one bump (33) and hold the roller (34) in position. A series of symbols (not shown) is marked on the periphery around the curved channel (35) and can be seen through the hole (140) in the first housing (10). A resilient block (36) corresponding to each symbol is mounted at a different angular position on an outer periphery of the roller (34), and each resilient block (36) has a concave face (361) defined in a top of the resilient block (36) to contact the corresponding CD.

[0017] The pivoting device (40) is mounted between the ears (11) of the first housing (10) and composed of an inner tube (41), an outer tube (42) and a coil spring (43) mounted between the inner tube (41) and the outer tube (42). The inner tube (41) is securely attached to the first housing (10), and the outer tube (42) is securely attached to the second housing (20). The outer tube (42) partially receives the inner tube (41) inside and the coil spring (43) has one end secured on the inner tube (41) and the other end secured on the outer tube (42).

[0018] The locking device (50) is attached on the second end of the housing (20) and comprises a clamp (51), resilient sheet (52) and a trigger block (53). The clamp (51) is mounted on the support plate (27) of the second housing (20), and resilient sheet (52) is V-shaped and has one side firmly inserting into the clamp (51). The trigger block (53) is pivotally attached beside the support plate (27) of the second housing (20) and has a cutout (54) defined in a side face toward the second housing (20). A tongue (57) laterally and outwardly protrudes from the trigger (53) and emerges from the lower notch (23). A hook (56) upwardly is formed on the trigger block (53) on a side opposite to the tongue (57) to buckle with the flange (16) of the first housing (16) and then lock the CD holder. Additionally, another side of the V-shaped resilient sheet (52) is attached in the cutout (54) of the trigger (53) whereby the resilient sheet (52) provides a restitution effect to the trigger (53) to re-lock the CD holder.

[0019] When the first housing (10) engages the second housing (20), the cross-section area of the chamber (A) of the first housing (10) between the cushion (12) and the selecting device (30) is larger than at least half the area of the CD. Therefore, the first housing (10) is able to encase the CD when the first housing (10) is opened.

[0020] With reference to FIGS. 1, 3, 4, and 5, when opening the CD holder, a user selects a desired CD by rotating the roller (34) until the corresponding symbol on the roller (34) is visible through the hole (140) in the first housing (10). Then, the resilient block (36) corresponding to the symbol presses an edge of the CD with the cushion (12) to hold the CD. After selecting the CD, the tongue (57) is pressed inwardly so that the hook (56) disengages from the flange (16) of the first housing (10), and the first housing (10) with the selected CD is automatically opened because of the stored torque in the coil spring (43). Whereby, the user enables to pick up the selected CD from the first housing (10) easily because the selected one is decided by the corresponding number and separated from other CDs in the second housing (20) when it is held by the opened first housing (10).

[0021] In addition, another embodiment of CD holder in this invention that the coil spring (43) is selectively secured on the pivoting device (40) in a reverse situation to provide a restitution force of keeping the CD holder closed. The locking device (50) can be omitted.

[0022] When closing the CD holder, the first housing (10) is pushed back to mate with the second housing (20), wherein the resilient sheet (52) provides a restitution force for the trigger (53) to make the hook (56) engage the flange (16) to lock the first housing (10).

[0023] As demonstrated in the foregoing description, the operation of the CD holder in accordance with the present invention is convenient for selecting and picking up the desired CD inside the holder.

[0024] Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
