FASTENING DEVICE Filed Nov. 2, 1937 eau cnyseriar No.

Patented Dec. 6, 1938 3 Claims.

@Th nvention relates to fastening devices, andimo're particularly, to a device for detachably the like onto an article of a t fi ilg a button or pport. This invention is an improvement over tlie'lstructure embodied in my co-pending appli- 136,107, filed April 10, 1937.

[object of this invention is to provide a device whereby" a button or another suitable articlfmaj'Y be quickly attached to a supporting device in such a manner that the article may be readily deta ched'from the support when desired I juring. the article or the support.

Y o r, object of thisz'invention is to provide an 1mprdv'ed"means"for detachably locking an article to a support. so. that the article may have movement" relative to the support without affecting disengagement of the article from the support.

With the foregoing and other objects in view, the invention will be more fully described hereinafter, and will be more particularly pointed out in the claims appended thereto.

In the drawing, wherein like symbols refer to like or corresponding parts throughout the several views:

Fig. 1 is a perspective view of a device constructed according to an embodiment of this invention.

Fig, 2 is a sectional view taken on the line 2-2 of Fig. 1.

Fig. 3 is a sectional view similar to Fig. 2 but showing the device during the initial assembly of the structure.

Fig. 4 is a sectional view partly in rear elevation taken on the line 4-4 of Fig. 2. v

Fig. 5 is an enlarged sectional view taken on the line 5-5 of Fig.

Referring to the drawing, the numeral I0 designates, generally, a cup-shaped or flanged button or article which it is desired to detachably secure to a supporting means which includes a face plate I and a flange l2, preferably integral therewith. A resilient annular member l3 in 'the form of a rubber ring or the like is disposed within the flange l2 and abuts against the inner side of the face plate II. An outer or rear plate I4 is secured within the flange I2 by any suitable means and is provided at its central point with a slot I5. A spring plate in the form of a disk member I6 is interposed between the rear plate It and the resilient annulus |3, and preferably is co-extensive with and normally in contact with the inner face of the rear plate I4.

A shaft or shank l1, having at one end laterally extending prongs H3, is adapted to engage tim JST TEs PATENT OFFICE Royal A; Young, Walsh, 0010. Application November 2, 1937, Serial No. 172,456

through the slot l5 and contact with the adjacent face of the spring locking plate IS. The shank or shaft H, at its other or outer end, is provided with a head |9 and a plate 20, loosely disposed on the shaft or shank H. An expansion spring 2| is mounted on the shaft or shank between the head l9 and the plate 20, and is adapted to constantly urge the plate 2|] toward the opposite or inner end of the shank H.

The rear plate |4 isprovided with an elongated detent, or recess 22, which extends at right angles to the slot l5 and constitutes a locking means in which the pin or laterally extending prongs l8 are adapted to engage when the device is detachably located on a support.

In the use of this device, the button member H) is placed on one side of a support, such as 23, and the shaft or shank I1 is projected through this support 23, or an opening such as a buttonhole or the like in this support 23, with the looking member I8 aligning with the slot IS. The plate 20 will initially contact with the face of the supporting member 23 opposite from the button ll], and in order to admit of the insertion of the inner end of the shank into the slot IE, it is necessary to compress the spring 2| with the plate 20 contacting with a face or side of the support 23. When the locking member I8 is inserted in the slot I5, the lock plate l6 will bend inwardly of the flange I2, and at the same time, the cushion member |3 will be compressed. The shank I1 is then given a quarter turn so that the locking pin I3 will engage in the detent 22.

The tension of the lock plate It will firmly hold the locking member l8 within the detent 22, and at the same time, the spring 2| will firmly hold the plate 20 against one side of the support 23 and pull the rear plate l4 against the opposite side of the support 23 so that the button II) will be firmly secured to the support 23. Release of the button H] from the support 23 is effected by compression of the spring 2|, and the turning of the shank so that the locking member I8 will be in register with the slot l5.

It will be obvious from the foregoing that an exceedingly simple fastening device has been provided for buttons, medals, or other articles, which is so constructed that the button or other article will be firmly held on the supporting member, and while the button may have some rotary movement relative to the supporting member, such rotary movement will not be of a nature .such that the button member ID and the shank will become separated. This is due to the yieldable holding plate It which yieldably holds the locking member l8 in the detent 22.

It is, of course, understood that various changes and modifications may be made in the details of construction and design of the above specifically described embodiment of this invention without departing from the spirit thereof,

such changes and modifications being restricted only by the scope of the following claims.

I claim:

1. A fastening device of the character described, comprising a hollow body having a front wall, an integral flange encircling said front wall and a back wall in the form of a plate secured to said flange in spaced relation with the front wall, said plate having a slot formed therethrough in the central part thereof and being pressed outwardly to form an elongated detent extending across and perpendicularly to said slot, an imperforate resilient disk within the body disposed fiat against the inner side of said plate, resilient means disposed against the inner side of said flange between said disk at the periphery thereof and said front wall, a shaft having a transverse bar at one end formed for insertion through said slot against said resilient disk and adapted to be turned by flexing said disk inwardly to dispose the bar across the slot in the detent, a head upon the other end of the shaft, a flat body having the shaft passing therethrough, and resilient means between the fiat body and said head normally urging the two apart.

2. A fastening means, comprising a hollow cup-shaped member, a plate carried by and closing said member and having an elongated slot in substantially the center thereof, a shaft having a substantially T-shaped inner end and a headed opposite end, a detent formed in said first plate at right angles to said slot, and a resilient imperforate disk plate in said member engageable with the T-shaped inner end of said shaft and against the inner side of said first plate to resiliently hold said T-shaped inner end of the shaft in the detent and maintain said shaft in locked position, the shaft being adapted to be turned by flexing said disk inwardly.

3. A fastening means, comprising a cup-shaped member, a plate carried by and closing said memher and having an elongated slot in substantially the center thereof, a shaft, a locking member carried by and extending transversely of one end of said shaft, a head on the other end of said shaft, a fiat body on said shaft, resilient means between the fiat body and said head and normally forcing the body and head apart, a detent formed in said first plate across and at right angles to said slot, a resilient imperforate disk of a diameter to position snugly in said member and disposed against the inner side of said first plate over said detent to engage and resiliently maintain said locking member in the detent, and a resilient annulus between said imperforate plate and the first plate and normally tending to maintain said imperforate plate flat against the first-mentioned plate, said shaft being adapted to be turned by flexing said disk inwardly to move the head into or out of said detent.
