Abstract

A system for inserting a compact disc (CD) into a storage tray (3) and for performing instant pop up of the CD over the clamps (6) by pressing a release button (5). By using this system the CD is protected against damage that might be done to the CD during the process of taking the CD out from the storage tray (3).

Description

Title of invention: COMPACT DISC (CD) INSERT - RELEASE SYSTEM.

The invention is described in the following statement;

The compact disc named (CD) is known as a device used to store data on it with a hole (K) in a centre, -(refer to FIG.1)

The CD insert - release system is designed to protect the CD against damage done to the CD by bending the CD or scratching on the active side of the CD during the process of taking the CD out from a storage tray.

The present invention provides simple operation to insert the CD into the storage tray and also provides instant pop up of the CD over the clamps by pressing a button.

The principle feature of the present system is the function of the release button (5) which is placed in the centre of the stored CD.

To assist with the understanding of the invention refer to the drawings: FIG.1 shows CD basic properties.

FIG.2, FIG.3 shows release button and spring.

FIG.4, FIG.5 and FIG.6 shows examples of the CD insert-release system function principles.

FIG.7 shows diagram of operation sequences.

FIG.8 accompanying the abstract

The RELEASE BUTTON (5) when pressed is arranged to activate all arms of a spring (4) and then to release the detents (10) located on the clamps (6). -(refer to FIG.2 and FIG.4)

The SPRINS (4) is designed to remain with no tension during the storage period. The arms of spring having push out projections (9) on each arm where the total number of the projections is 3 (three) or more, -(refer to FIG.3) The PROJECTIONS (9) are integrated with the spring (4) and are engaged to pop up the CD over the clamps (6). The top surface of all the projections (9) are used also as the storage place for the CD during the storage period, -(refer to FIG.4) The CLAMPS (6) are integrated with the storage tray (3) and are engaged to keep the CD firmly in the storage position, -(refer to FIG.4)

The STORAGE TRAY (3) comprise the clamps (6) and is permanently placed in a storage box (2). -(refer to FIG.3)

The DETENTS (10) are engaged to arrest the CD and are integrated with the damps (6) where the total number of detents is 3 (three) or more. - (refer to FIG.4)

The release button (5), the spring (4), the storage tray (3) with the clamps (6) and the detents (10) all may be made of any suitable material, such as moulded plastic or metal. Referring to FIG.2 and FIG.3 it can be seen that the release button (5) and the spring (4) can be manufactured as separate parts. The lower enlarged end (8) of the release button (5) is designed to be clicked in, and permanently held in the center of all clamps (6).

The pivoting points labelled (C) are located on each spring arm with an empirically defined equal distance from the centre of the spring (4) to suit required tension in spring based on material properties.

Referring to FIG.4 it can be seen that the CD is in storage position. Also it can be seen that the gap labelled (D) is designed to provide relevant tension in the spring (4) after the button (5) has been pressed down as much as is necessary to pop up the CD over the clamps by the projection pins (9). The gap labelled (E) is designed to provide space for total movement of the release button (5) to come down. The gap labelled (G) is provided to keep clearance between the storage tray and the active side of the CD during the storage period. The gap labelled (F) between the release button (5) and all of the clamps (6) is designed to perform concentric movement of all the clamps (6) required for both major operations; one to put the CD in storage position and another is to release all detents (10).For smooth operation purpose the chamfer labelled (B) is provided on each clamp (6).

Referring to FIG.5 it can be seen that the CD is out of clamped position. Also it can be seen that the location of all the top surface of the projections (9) are defined as the area with no bigger diameter than the standard core area (L) free of recorded data on the CD.

- (refer to FIG.1 and FIG.5).

Referring to FIG.6 it can be seen that the shape and the size of the core hole labelled (H) in storage tray (3) is designed to suit the sizes of the spring (4) and the release button (5).

Claims

The claims defining the invention are as follows:

1. A compact disc (CD) insert-release system as a device comprising a release button, a storage tray, a spring, a clamp, a projection and a detent to perform operations of inserting said CD into said storage tray and to perform instant pop up of said CD over said clamps by pressing said release button which is placed in the centre of the stored said CD.

2. The compact disc (CD) insert - release system as a device of claim 1 wherein said release button comprising a lower and an upper enlarged ends is engaged to energise all arms of said spring.

3. The compact disc (CD) insert - release system as a device of claim 2 wherein said lower enlarged end of said release button is permanently held in the centre of all said clamps and said upper enlarged end is engaged to contract all said clamps during the movement down and than subsequently to release all said detents.

4. The compact disc (CD) insert - release system as a device of claim 1 wherein said storage tray comprise a core hole and said clamps.

5. The compact disc (CD) insert - release system as a device of claim 4 wherein said clamps comprises said detents where the total number of said detents is 3 (three) or more.

6. The compact disc (CD) insert - release system as a device of claims 1 and 2 wherein said spring comprise said arms having push out said projections on each said arm where the total number of said projections is 3 (three) or more.

7. The compact disc (CD) insert - release system as a device of claims 2 and 4 wherein said core hole is arranged to suit the shapes and sizes of said spring and said release button.

8. A compact disc (CD) insert - release system as a device substantially as herein described with reference to the accompanying drawings.
