Key ring arrangement

The invention relates to a key ring assembly comprising a circular key ring holder with an annular groove on the periphery thereof for securing a key ring for holding a number of keys by means of operation of a release pin in cooperation with a connecting pin, a coil spring, a piston and a slide pin.

In everyday life, we often use a variety of keys to open doors to houses, offices, cars, etc. Since different keys are often used, they must always be carried around ready for use.

BOEHMERT & BOEHMERT, NORDEMANN pnd PARTNER

To carry a large number of keys with you, a key ring is usually used. In order to carry the key ring with you, different key ring holders have been developed which can be attached to a belt in a suitable manner. A disadvantage of such conventional key ring holders is the complicated process of attaching a key ring to the key ring holder or removing the key ring from it.

The invention has been made in view of these disadvantages. According to the invention, there is provided a key ring assembly comprising a circular housing having an opening on an annular groove operable to open and close by means of a release pin, a coil spring, a piston and a slide pin, allowing a key ring to be releasably secured in the annular groove for holding a number of keys.

In the following, the invention is explained in more detail using a preferred embodiment with reference to the attached drawings.

Fig.l shows a preferred embodiment of the invention;

Fig.2 is an exploded perspective view of the preferred embodiment of the invention

Fig.3 is a sectional view of the preferred embodiment of the invention.

The accompanying drawings show in detail that the invention essentially comprises: a housing 1, a key ring 2, a coil spring 3, a release pin 4, a piston 5 and a sliding pin 6. The housing 1 has an annular groove 11 around its circumference

BOEHMERT & BOEHMERT, NORDEMANN and PARTNERS

around, with a cylindrical opening 13, an opening 14 and a keyhole 15 formed between two opposing annular edges 12. The key ring 2 has a connecting pin 21. The release pin 4 is provided with an annular groove 41 at one end. The piston 5 comprises an upper cylindrical projection 52 at one end, a thickening 51 in the middle and a lower cylindrical projection 53 at the opposite end. The sliding pin 6 comprises a recess 61 at one end, two round through-openings 62 and 65, a one-piece tubular part 63 and a partition wall section 64.

To assemble, the coil spring 3 is placed on the lower cylindrical projection 53 of the piston 5 and then inserted into the tubular part 63 of the sliding pin 6. The upper cylindrical projection 52 is inserted into the round through hole 65 and then secured within the cylindrical opening 13 of the housing 1. The release pin 4 is inserted through the keyhole 15 of the housing 1 into the round opening 62 of the sliding pin 6, allowing the upper cylindrical projection 52 of the piston 5 to engage the annular groove 41 of the release pin 4.

When the release pin 4 is moved downwards in the keyhole 15, the piston 5 and the slide pin 6 are moved to compress the coil spring 3, allowing the opening 14 of the housing 1 to be open for attachment of the key ring. This allows the connecting pin 21 of the key ring 2 to be secured through the opening 14 within the annular groove 11 of the housing 1 to be retained therein or to be removed therefrom without great effort. The connecting pin 21 may have a ball head or a large cylindrical head for easy securing in the annular groove 11 of the housing 1 by

which have opening 14.

A fastening element 71 can additionally be fastened to the housing 1 by means of a chain 7.

In the event that the fastening element 71 is not directly attached to the housing 1, a further fastening element 75 can be provided, which serves to connect the key ring holder to the fastening element 71.

The features of the invention disclosed in the above description, the claims and the drawings can be essential both individually and in any combination for the realization of the invention in its various embodiments.
