ABSTRACT:

FIELD OF INVENTION
The invention is a device for the removal of compact disks from their containers. Compact disks are usually packaged in plastic boxes, containing a holder tray which keeps the disk immobile with resilient fingers in the central opening of the disk. To take the disk out it is necessary to the depress the fingers and at the same time lift the disk out. This is a conflicting movement. The invention makes it easy to remove the disk, in that by pressing the device a spring lifts the disk and the disk can easily be taken out. The invention is meant in particular for those holding trays with twelve resilient mounting fingers.
BACKGROUND OF INVENTION
For holding trays with eight resilient mounting fingers there is a device described in PCT application WO 94 05010. This device is not fit for use in a holder tray with twelve mounting fingers because the space between the mounting fingers is limited especially towards the center. While the spring has to be strong enough to lift the disk, there is a limit to the width of the spring. Mounting the device is impossible because the spring will not pass between the fingers and would be bent and thus rendered useless.
For holding trays with 12 mounting fingers there is a device known from European patent application EP-A-429195. A four-armed spring urges the disk upwards when the mounting fingers are pressed, This publication describes also a push button with pivoting arms. Both applications have the arms resting upon the resting surface of the container, resulting in less gripping surface of the mounting fingers and only a four point resting of the disk. This could lead to deformation of the disk.
SUMMARY OF INVENTION
The invention offers an improved device which is reliable in lifting the compact disk when the device is pressed. To obtain this feature the device has supports for the spring which prevent deformation of the spring and widen the space between mounting fingers. Rotation of the device is also prevented by the spring support.
