(6i. 7d45) This invention relates to a key holder, and more particularly to a pocket key holder for holding one or more keys in a normal sheathed storage condition for carrying in a pocket or purse without the danger of the sharp edges or corners of a key tearing the cloth or injurin the person.

An object of the invention is to provide a key holder for one or more keys in which the key may be retracted to a sheathed storage condition or extended outwardly to a use position.

Another object of the invention is to provide such a key holder in which the key is automatically releasably locked in both the retracted and extended positions upon manual movement of the key to these positions.

Another object of the invention is to provide a novel over-center spring locking mechanism to automatically releasably lock the key in the retracted and extended posi tions.

A further object or": the invention is to provide a key holder constructed of a minimum of parts which may be readily manufactured by standard techniques to provide a low cost structure.

A still further object of the invention is the provision of means for securing keys of diil rent sizes and shapes to the holder .1 echanism.

Other objects of this invention will appear in the following description and appended claims, reference being had to the accompanying drawings forming a part of this specification wherein like reference characters esignate corresponding parts in the several views.

In the drawing:

FIGURE 1 is a view in perspective view of one embodiment of the key holder of the present invention;

FiGURE 2 is a plan Vi w of the key holding mechanism of FIGURE 1 with the outer casing removed and the key shown in the retracted or storage position;

FIGURE 3 is a plan view of the key holding mechasimilar to FIGURE 2 with the key shown in the extended or use position;

FIGURE 4 is a right end eievational view of the key holding mechanism of FIGURE 2; and

FIGURE 5 is a view in perspective of a key showing the key retaining plate utilized in the key holding mechanism secured to one face of the key head.

Before explaining the present invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and arrangement of parts illustrated in the accompanying drawings, since the invention is capable of other embodiments and of being practiced or carried out in various ways. Also, it is to be understood that the phraseology or terminology employed herein is for the purpose of description and not of limitation.

Referring to the drawing, it may be seen that the key holder i comprises an outer casing 12 in which is mounted a key holding mechanism 14. The outer casing 12 is fabricated from a plastic material and includes a pair of side walls 16, 13 joined together along one edge by a bottom wall 2% and joined together at the opposite edges by

corner members

22, 24. This construction leaves the ends 25, 28 and top 3% open. The open ends permit the insertion of the key holding mechanism 14 into the casing. The open top permits extending the

keys

32, 34 outwardly for insertion into a lock.

The key holding mechanism 34 comprises a generally rectangular plate 36 having a length greater than its width ice to accommodate the normally elongated shape of a key. The plate carries two

keys

32, 34. However, if desired, the device may be constructed to carry only one key or additional key holding mechanisms may be secured to either the ends or sides to provide for the mounting of more than two keys.

A relatively thick spacer element 38, 4! is secured to each side of the plate 3%? by a plurality of pins 42. The spacers comprise

end portions

44, 46 joined together by a longitudinally extending portion 48 to form a recess for the keys. The recess is confi ured to permit clearance for pivoting of the keys.

The spacers 38, serve two functions. One function is to position the plate 36 centrally within the outer casing 12 and fric-tionally secure the key holding mechanism within the outer casing. The second function of the spacer is to provide stop surfaces 59, 51 to limit the pivotal movement of the keys.

The keys are pivotally mounted on a pin 52 which is secured to the plate 36. The pin 52 is mounted adjacent one longitudinal end 54 of the plate and extends outwardly in both directions for the pivotal mounting of two keys.

As shown in FIGURE 5, each key is provided with a retaining plate 56 which is adhesively secured to one face of the key head 58. The keys are of conventional configuration, having an opening 6%) in the head 58 and an elongated lock-engageable member 62 extending therefrom.

The retaining plate 56 has an opening 64 which is in registry with the opening of the key. A pair of

tabs

66, 58 are provided on the retaining plate. Each tab extends frcrn the periphery of the retaining plate upwardly along the side of the key and then outwardly in a plane substantially flush with the key face. The tab 66 is provided for securement of an actuating button '76. An opening 72 is provided in the tab to threadingly receive the threaded shank 74 of the button 79. The shank 74 extends through an elongated arcuate opening 76 in the side Wall of the outer casing and terminates in an enlarged head. The button 76 permits manual pivoting of the key. The extent of pivot is determined by the length of the opening 76, the ends of which act as stops. The button 7% also functions to securely hold the key holding mechanism 14 within the outer casing 12.

The second tab 68 on the retaining plate 56 has an opening 73 to receive a rivet 89 for the pivotal attachment of an arm $2, forming part of the key locking mechanism. As will be noted in FIGURE 2, the key 332 is inserted over the pin 52. In the normal retracted position, the outer end of the member 62 rests against the stop surface 5%. The tab 63 is positioned adjacent the end 54 of the plate as and near the outer edge of the plate above the axis of the pivot pin 52. The arm %2 extends across the key and terminates adjacent the edge or" the key. One end of a coil spring 34 is attached, by Jeans of opening 86, to the arm. The other end of the spring 84 extends into engagement with a pin 88 projecting from the plate 36.

When it is wished to extend the key out of the holder, the button it? is moved in the arcuate opening to pivot the key about the pin 52. As shown inFIGURE 3, the key will come to rest in the extended position when the key head abuts against the stop surface 51. As will be appreciated, during pivoting of the key, the arm 82 and spring 84 pass over the longitudinal axis of the pin 52 and come to rest at a point below the pin. The spring 86 thus exerts a force through the lever arm defined by the distance between the rivet and the pin 52. This force keeps the key in the extended position until it is actuated back into the retracted position. When the key is retracted, the spring 80 then exerts a force tending to keep the key in the retracted position.

The key holder thus described may be readily manufactured on a commercially economical basis. The plate 36, retaining plate 56 and arm 82 may be fabricated by stamping using automatic machinery. Alternatively, the platefi and

spacers

38, 40 may be molded from plastic as an integral unit. The spring and pin are available as stock items, thus resulting in an overall construction which is of very low cost and admirably suited for such a device which must be distributed as an inexpensive item,
