4 Claims.

This invention relates to a key holder of the type usually attached to a chain for providing a key package to be worn on the person.

One of the objects of this invention is to provide an easily operable key holder which may be opened or closed for mounting of the keys so that the same will be simple and inexpensive to manufacture, yet positive in its operation so that when closed, the same will not accidentally open.

Another object of the invention is to arrange the construction such that it may be made of a minimum number of parts arranged in an advantageous relation.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended. claims.

In the accompanying drawing:

Fig. l is an elevation illustrating the key holder in closed position with a fragmental portion of the key shown as mounted thereon and a fragmental portion of the chain attached to the holder;

Fig. 2 is a sectional view through the closure member, illustrating the locking arrangement of the parts;

Fig. 3 is a view similar to Fig. 2, but showing the closure member in open position;

Fig. 4 is a View similar to Figs. 2 and 3, but illustrating a different relative position of the closure member to the loop-shaped body;

Fig. 5 is a section on line 55 of Fig. 2;

Fig. 6 is a sectional view showing the cross sectional shape of the loop-shaped body.

This invention utilizes the resiliency of a loopshaped body by the forcing apart of the spaced ends of the body which, being under some tension from the forcing apart of the ends, tend to spring together, the urge of the springing together being utilized to lock the closure member in position, the ends being cammed to or from closed position by a suitable shaping of the surfaces which slide one upon the other.

With reference to the drawing, I designates the resilient body which is here shown as curved in shape generally in the form of a loop with its ends I l and I2 spaced. These ends may be sprung apart, and when so moved apart, will tend to return to their normal spaced relation. The hinged closure member [4 consists of side walls l and a bottom wall l6. These side walls receive between them one end portion II of the body It, and this member is mounted in pivotal relation by means of the pin I1 extending through the walls and the end portion II and eing headed as at l8 over the side walls. The walls are also provided with an opening l9 which receive a ring 20 linking it to a chain 2| for attaching the holder to the belt or trousers or any other suitable part of the clothing.

The end [2 of the loop-shaped member is rounded as at 22, the shape being somewhat tapered, as perhaps best shown in Figs. 2, 3, and 4, while a cam-shaped block 23 is secured to the bottom wall 16 of the closure member I4. This block is located between the walls l5 and may be soldered or riveted or otherwise suitably secured in such position as shown in Figs. 2, 3, and 4, where it may be rigidly supported with the closure member M. The position of this cam 23 is such that its edge surface 24 will engage the rounded end 22 of the loop it! as the member I4 is swung on its pivot I? so as to move in substantially the are shown in Fig. 4 by the dotdash line 25, and in so moving it will force the end I2 away from the end ll until the cut-away portion 26 is reached, when this end I2 will then snap into the cut-away portion beneath the abutment 21 where the end 22 fitting into this recess and back of this abutment will hold this closure member in closed position. To open this member l4, sufficient force is exerted to move the member l4 inwardly so that its abutting surface 21 will move past the curved end 22 of the end portion l2 of the loop body when a key may be mounted on or removed from the body.

I claim:

1. A key holder comprising a loop-shaped resilient body with its ends spaced, a channel member having side walls hinged to one of said ends and of a length to receive the other end between its side walls when swung on its hinge toward said other end, a catch between the walls of said member provided with a recess to receive the end of said body, the location and shaping of said catch and end of the body being such as to hold the parts together in interfitting engagement, said holding in such position being assisted by spreading the ends of said body when the member is swung on its hinge to closed position.

2. A key holder comprising a loop-shaped resilient body with its ends spaced, a channel member having side walls hinged to one of said ends and of a length to receive the other end between its side walls when swung on its hinge outwardly toward said other end, a catch between the walls of said member having a recess to receive the said other end of the body, and a cam surface leading to said recess to spring the spaced ends of said body apart as swung just prior to the positioning of said end in said recess.

.3. A key holder comprising a loop-shaped re-' silient body with its ends spaced, a channel memher having side walls hinged to one of said ends and of a length to receive the other end between its side walls when swung on its hinge outwardly toward said other end, a catch between the walls of said member having a recess to receive the said other end of the body, a cam surface leading to said recess being located a distance from said hinge connection to spring the spaced ends of said body apart upon swinging just prior to the positioning of said end in said recess, and a chain connection to said member tending to move the same outwardly.

4. A key holder comprising a loop-shaped resilient body with its ends spaced, a channel member having side walls receiving between them and hinged to one of said ends and of a length to receive the other end between its side walls and along its bottom wall when swung on its hinge outwardly toward said other end, a block between the walls of said member having a recess to receive the said other end of the body, and a cam surface leading to said recess to spring the spaced ends of said body apart upon swinging just prior to the positioning of said end in said recess.
