7 Claims.

This invention relates to wrist bands suitable for wrist watches and the like and particularly a wrist band suited to fabrication from thin, resilient, flexiblesheet material.

Wrist bands of the type in consideration, made'f from thin, resilient sheet material such as stainless steel, because of the absence of the usual pli- I ability of leather and other often used materials,

are in many instances provided with buckles I which are complicated, unusual in operation, and fnot readily operable. It is an object of the present invention to provide in a metallic strip band, a buckle that is extremely simple, easy to operate Another object of the invention is to provide a buckle and strap which may be readily stamped from ordinary thin resilient sheet metal or like material and thereafter economically assembled.`

A further object of the invention is to provide a buckle and strap which is pleasing in appearance and not bulky, and which may be taken off or placed upon the wrist of the wearer by the simple sliding of the ends into overlapping position.

The above and other novel features of the invention will appear more fully from the following detailed description when taken in conjunction with the accompanying drawings. It is expressly understood, however, that the drawings are employed for purposes of illustration only and are not designed as a denition of the limits of the together in any desired position by reason of a novel buckle, generally indicated at I9.

In order to render the strap adjustable lengthwise at the buckle, the tongue portion 2S of the strap I is perforated by a series of apertures 22, through any one of which a hook 24 may be projected. The vhook 24, is formed on the end of a narrow longitudinally extending ringer or strip 26, having at its other end a transverse flat collar 28, slideably arranged upon the tongue 2l). The hook is sulciently small to be readily extended through any one of the apertures 22 and may be resiliently flexed or slightly inclined to facilitate such insertion.

The hook 24 is adapted to reach through one of the apertures 22 only a sufficient distance to receive easily the thickness of the metal from which the buckle frame 3i] is formed. The buckle shown in Figure 2 lies as nearly flat as possible,

i sleeve 3S is slidably arranged on the strap I2, and

invention, reference being had for this purpose to the appended claims.

In the drawings wherein similar reference char.- acters refer to similar parts throughout the several views:

Figure 1 is a perspective view of the wrist band as it would appear when worn on the wrist,

Figure 2 is a side elevation of the buckle,

Figure 3 is a top plan View of the buckle,

Figure 4 is a bottom plan view of the buckle, and

Figure 5 is a side elevation of the buckle with the ends separated.

Referring to the drawings and particularly to Figure 1, the strap will be seen as composed of `two strap members I0 and I2, joined through a Watch I4, through the rolled loops I6 and I8. The straps may be made of noncorrosive metal such as stainless steel, having resiliency, but also capable of being deformed to closely conform to the contour of the wearers wrist. The strap members are adapted to be overlapped and secured is adapted to betelescoped over the tongue 25J, up toward the rolled eye 32 to clamp the strap I2 and tongue 20 lightly together and hold all the parts in buckled relation.

The ease with which the parts may be buckled together and released is shown in Figure 5. By sliding the sleeve 3B to the right, the straps may be moved toward one another to allow the buckle to be released from the hook 24 and lifted slightly, after which the parts are readily separated. To clasp the parts together it is only necessary to extend the tongue 20 through the buckle window 3| and thereafter hook the buckle 30 on the hook 24, after which the sleeve 36 is moved to the postion shown in Figure 2.

The hook 24 may have been previously positioned in the proper aperture to provide the degree of snug fit desired by the wearer. The parts, in assembling, approach one another in practically their normal buckled position permitting the operation previously described without danger of pinching or producing any discomfort whatsoever. The band may be Worn more snugly for this reason. At no point are there more than two layers of overlapped metal for any distance so that flexibility is not seriously impaired, and once the band is formed or molded to fit the wearer, by springing the metal beyond its elastic limit, the fit is so perfect and the weight so slight that the wearer is hardly conscious of its presence.

It will be readily apparent that all the parts are readily formed from thin sheet metal if desired. Also, if desired, the hook sleeve 28, and telescoping sleeve 36, may be soldered or otherwise secured where the ends meet, as seen in Figure 4. However, the sleeves should have a sliding t neither -too loose nor too tight, so that once positioned,they will remain in such position.

Although but a single modification of ltheinvention has been shown anddescribed, it is to .be understood that various alterations, and changes in proportion and selection of material .may be made witho-ut departing from the spirit of the invention, as will be V-well understood by those skilled in the art. `Reference will therefore be had to the appended claimsfor a definition of the limits oi the invention.
