Abstract
A housing with a retaining device is arranged on a base plate and comprises clamping studs which are arranged in a circle, which are radially resilient, and which have clamping surfaces facing radially outwards for gripping into a central opening of at least one disc-shaped information carrier, for example a CD. To avoid a destruction of the clamping elements in the case of impacts, rigid support studs with support surfaces facing radially outwards are provided between the clamping studs, and the diameter of the support surfaces arranged in a circle is somewhat smaller than the diameter of the central opening of the information carrier.
Claims18
A housing comprising:
- an enclosure:
- a base plate within the enclosure:
- and
- a retaining device which is arranged on the base plate, the retaining device includes:
- clamping studs which are arranged in a circle, which are radially resilient, and which have clamping surfaces facing radially outwards for gripping into a central opening of at least one planar disc-shaped information carrier, and
- rigid support studs with support surfaces facing radially outwards are provided between the clamping studs,
- and in which:
- the diameter of the rigid stud support surfaces arranged in a circle is approximately equal or somewhat smaller than a diameter of the central opening of the at least one information carrier;
- and
- the clamping studs include at least two structurally different groups of clamping studs.
A housing for planar disks, comprising:
- a central part,
- two identical lid parts hinged to the central part, and
- a respective tray which can be inserted into each of the lid parts, the two trays each including;
- a base plate;
- a retaining device integral with the base plate, including:
- clamping studs arranged in a circle, radially resilient, and with clamping surfaces facing radially outwards for gripping central openings of multiple parallel disks, the clamping studs including multiple groups of clamping studs, each group defined by a structurally different clamping surface for gripping a respective disk;
- support studs arranged in the circle between the clamping studs, radially rigid, and connected to a common planar rigid support element.
A housing for planar disks, comprising:
- a substantially transparent enclosure;
- a base plate within the enclosure;
- a retaining device integral with the base plate, including:
- clamping studs arranged in a circle, radially resilient, and with clamping surfaces facing radially outwards for gripping a central opening of a disk;
- support studs arranged in the circle between the clamping studs, radially rigid, and connected to a common planar rigid support element;
- and
- reinforcement ribs provided at the connections between the support element and the support studs, the ribs tapering to reduce material use.
A disk support device, comprising:
- a base plate;
- and
- a retaining device integral with the base plate, the retaining device includes:
- clamping studs which are arranged in a circle, which are radially resilient, and which have clamping surfaces facing radially outwards for gripping into a central opening of at least one planar disc-shaped information carrier, and
- rigid support studs with support surfaces facing radially outwards provided between the clamping studs,
- and in which:
- the diameter of the rigid stud support surfaces arranged in a circle is approximately equal or somewhat smaller than a diameter of the central opening of the at least one information carrier;
- and
- the clamping studs include at least two structurally different groups of clamping studs.
