ABSTRACT:
DESCRIPTION
TECHNICAL FIELD
The present invention relates to a disc storage case, and particularly to a power-driven disc storage case.
BACKGROUND OF THE INVENTION
A general disc storage case or cabinet is used to arrange covered discs in a disc storage case, with the discs numbered and labeled on the cover, in order to distinguish and drawn them out for use. Typically, during selection, it is necessary to find the shelves one by one for the required disc, and after pulling the disc out, the cover must be removed before use.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a power-driven disc storage case for holding discs.
It is a further object of the present invention to provide a serious of cases piled up by a number of power-driven disc storage cases.
The power-driven disc storage case of the present invention comprises an outer casing, a chassis, a rolling top, two drawers, a face plate, two button switches located on both the left and right side of the front face plate, two lamps on the back of the face plate, an outer socket for connecting DC power supply at the back of the storage case and an electric cell chamber under the chassis, a power-driven selective conveyor located on the chassis which involves a plurality of disc brackets, each of which having two arc-shaped grooves for holding vertically two discs which are placed back-to-back so that the contents printed on the disc can be easily read. The chassis further includes a contact main switch, which can be stricken by the rolling top while it is open to connect the power supply, causing the lamps to light and illuminate the discs on the brackets in the front opening of the storage case; a micro high-speed DC motor which can rotate towards one direction to make the bracket of the disc move clockwise when the left button switch being pressed and can rotate towards another direction to make the bracket of the disc move counterclockwise when the right button switch is pressed; a transmission with safety protective mechanism, which can be driven by the micro high-speed DC motor to have the bracket of the disc move while any one of the two button switches are pressed continuously, and is stoppable by releasing the button switch when the desired disc is forwarded to the front position.
In connection with the disc storage case of the present invention, the transmission consists of a plurality of transmission gears and a transmission chain, such gears make up an underdrive gear set that reduces the rotation rate of a high-speed D.C. motors to an adequate driving speed of the transmission chain, on which a plurality of brackets for the discs are installed.
The disc storage case of the present invention, wherein the safety protective mechanism of the transmission comprises a belt, speed reducer and chain belt, the belt as first-stage belt functioning for vibration-resistance noise elimination and overload protection.
The disc storage case of the present invention comprising a plurality of brackets for discs from
12
to
60
.
A series of the disc storage case of the present invention, comprising a plurality of the disc storage cases and a plurality of fixing accessories, by which a plurality of such cases can be piled up and fixed to act as a series of the disc storage case.
An advantage of the disc storage case with power-driven selective shelf of the present invention is that it can hold many kinds of discs; for example, CD, CD-ROM and VCD. If another kind of disc bracket with somewhat different dimension is used, it can also hold DVD and floppy disc.
A further advantage of the present invention is that the disc storage case has a hand-pushed rolling top with convenient operation, rustproof and artistic appearance.
A further advantage of the present invention is that the disc storage case is compact and exquisite, while 100 uncovered discs can be held in a disc storage case of 44 cm×26 cm×16 cm only. The description for the discs, such as words of a song, etc., can be put in a small drawer thereon.
A further advantage of the present invention is that, after the rolling top of the disc storage case is opened, the lamp therein lights at once and shines on the disc in the front of the case. Gently pressing the shift button of any one of both sides, the bracket will be transferred and will not stop until the button is released while the disc needed moves to the front. The user can take out the disc with ease after the disc stops at the position of the opening of the rolling top.
A still further advantage of the present invention is that, when the number of discs is more than 100, then several disc storage cases may be piled up and fixed with fixing accessories to a series of disc storage cases for saving space and having splendid style.
Another advantage of the present invention is that the transmissions in the disc storage case are equipped with safety protective mechanism, which can prevent motor damage due to overload and caused by obstruction or improper application in the process of operation.
Another advantage of the present invention is that the rear of the storage case has an outer connection DC electric supply socket.
A low-voltage output (for example, 3 volts) plug of AC-DC adaptor may be connected, so the common AC supply can be used instead of using cells power.
