The innovation concerns a chipboard holder for the upper holding of chips and a chipboard bundle, consisting of a disc, the handle of which is provided with a recessed groove at the back, into which preferably spherical receiving elements for the chipboards being held can be inserted via a break-through.

A glass holder of this type is known, for example, from the German customary specifications 19 00 399 and 85 00 204, in each of which an opening is provided in the pane which is closed by a relatively complex slide.

Experience shows that an average of four keys are attached to such a key holder. To replace or remove a key, it is therefore necessary to either remove the key from the first or second position or to move it over the opening point . 01.01.2004 To avoid removing two lines of keys, the innovation according to the Federal Gazette IS 00 204 is to attach two sliders to the key ring.

If the openings are closed by such slides, they are still fragile and have already proven themselves in very large quantities, but due to the slide construction they are relatively difficult to manufacture and relatively expensive.

The aim of the innovation is to provide a key holder of the type described, which, however, is literally terrific compared to the old slide valves. In this new way, it is made impossible by the fact that the breakthrough is a labyrinth-shaped channel cut behind a disc and open on a forte.

Unlike the known designs , the opening required for inserting and removing the keys is not closed by a slide, but the accidental falling out of the key holders is prevented by the opening turning into an undercut channel.

labyrinth-shaped up to an exit opening from which the receiving elements can be removed. This ensures that the receiving elements remain in the undercut groove just as well as with the slider in the known designs, but without the need to insert a complex and therefore expensive slider into the key holder. If the breakthrough is also provided with a wave that narrows the breakthrough preferably at the base, this not only ensures good sliding of the spherical receiving elements over the breakthrough, but also ensures that the receiving elements " eight

For the economical manufacture of the key holder, it is proposed that the disc is divided in a central disc plane or in a disc plane lying at a height of the self-use of the rear-cut disc and that in the case of the latter execution the divided disc is provided with a surrounding circle forming the base of the disc and broken through at the break, as well as within the circle broken through by the circle with a ribbed

^ Both versions

allow a very simple design of the injection molding tools required for the injection molding of the screw holders, so that the end product can ultimately be manufactured economically.

The labyrinth-shaped channel can have any design, but is preferably designed in a spiral shape or in the shape of letters, so that this technically necessary channel design also provides an advertising opportunity.

·

The external design of the key holder according to the innovation is arbitrary; it can be circular, as shown in the drawing, but can take on any shape, for example rectangular, square, triangular or generally more angular.

The innovation is shown on the attached diagram.
