4 claims. (ci: 63-11) i 'rm's"mentionv relates to wrist watch bands,

Aand more particularly to watch-bands of resilient construction adapted to be slipped over the hand and' to take a shape corresponding to the shape of the wrist.

Heretofore resilient plastic watch bands have been employed, but it has been found that the piastic material most commonly' used i. e. vinyiite causes a skin irritation, -possibly due to lack of ventilation between the band and the wrist and partially due possibly'to an allergic reaction in some people.

However, itis the object of this invention to terial having a substantially high tensile strength.

employ a highly resilientv plastic material for a watch band, but to use In combination therewith means for maintaining a spaced relation between the elastic band and the wrist in order to secure proper ventilation, and also to keep said bandout of contact with the skin.

It is the further object 'of this inventionv to employ a plastic member coiled or otherwise disposed over the elastic band for covering the-same and for maintaining a spaced relation between said band and the wrist of a wearer.

It is the further object of this invention .to

provide plastic means attachable to the ends of 'y band as applied to the wrist.

the elastic watch band for securing the same to a watch.

The invention relates to the various elementsA and their combinations las hereinafter described in detail in connection with the appended drawing of which:

Figurev lis a perspective view ofthe watch Figure 2 is an elevational view oi.' panded watch band.

Figure 3 is an elevational view of the watch band in expanded position.

Figure 4 is a cross-sectional view on line 4 4 of Figure 2.

Figure 5 is an enlarged sectional view taken on the line I--l of Figure 3 and showing in dotted lines, the watch balls to which the ends of the watchband are secured.

.The above drawing illustrates merely a preferable embodiment of this invention, it being understood that other similar constructions are equally adaptable within the scope of the invention as hereinafter set out in the following speciflcation and claims. f l

In the drawing, the wrist watch band consists of a tlat thin elastic member II made. of a suitthe unerrable elastic 6r resilient material such as Vinyl-y ite. Vinylite is a highly'plasticized plastic ma- The member I2 is also made of plastic material, preferably cellulose acetate, and is coiled about the length of the elastic member II as shown in Figs. 2 and 3 of the drawing.

It is understood that the above material is merely a preferable embodiment and that any. other suitable covering material kmay be employed.

Member I2 consists of a continuous tight coil obtained by winding the material on a spinning core on a lathe.`

It will be understood that the exterior surface of the coiled member I2 is arcuate or curved whereby only point or line contact is made with the wrist of the wearer. The advantage of this resides in the'fact that almost complete ventilation is obtained with no discomilture.

Said coil however may be of any other suitable shape, or on the other hand may be merely 'a covering member through which the elastic strip I I is longitudinally disposed.

In applicants preferred embodiment said coil is heat treated to guarantee that itsv shape is maintained; and so coiled also has a certain amount of resiliency.

Watch securing means I3 and Il are provided at opposite ends of members Il and I2. 'I'he watch securing means may be made of a plastic material or any other suitable material y such as,` leather, fabric, etc. .In attaching the watch securing means to the watch band, the member I3 is rst looped-about the last convolution of the coil'rnember ll'and the free ends thereof passed about the endof the strip Il to form loops I1 and I8 as shown in Figures 1 and 5 voi the drawing. The ends of the member I3 are then secured to the strip II by means of staples I5. It is obvious that lines of stitching at this portion of the end members I3 and Il could be effectively used to secure the various parts together. Thus it will be seen that the watch se- Y curing members I3 and Il alsoserve asmeans for maintaining the coiled member'i! in place on the elastic strip Il.

As constructed a very neat appearing band is provided which is entirely resilient for slipping over the hand of a wearer but at the same time causes no discomiiture. r

By providing ajlimited contact area in each loop of the c iiled member I2 a substantial ventilating effect is obtained thereby assuring wearing comfort.

By the provision of a unitary elastic member of elasticized A|.I and the coiledmember I2 it is seen that no mechanical adjustment isrequired and furthermore said band is adaptable to any shape of wrist. It will be understood that members I3 and VIl may be otherwise constructed as long as suitable means are employed for securing the ends of the wrist watch band-to the watch.

Having described my invention in detail, reierence should now be had to the claims which v follow for determining the scope thereof.

v I claim:

1. A wrist band comprising a. strap of elas ticized plastic material, a coiled member longitudinally disposed around said strap, and watch attaching means secured to opposite ends of said strap, said watch attaching means also securing said coiled member in proper position on said strap. l y

2. A wrist band comprising a ilat thin strap plastic material, a fiat coiled member disposed about-said strap, and watch attaching means secured to the ends of said strap, said watch attaching means also securing the said coiled member in proper position on said strap.

3. A wrist band comprising a strap of elasticized plastic material, a coiled member disposed about said strap, said member comprising a at series oi' convolutions extending substantially the length o f said strap, and watch attaching means secured to opposite ends of said strap for engagement with a wrist watch.

4. A wrist band comprising a at thin strap of elasticized plastic material, a coiled member disposed about said strap, said member comprising a series ot at convolutions extending substantially the length ofv said strap, and watchv .attaching means secured to opposite ends of said strap, said watch attaching means also securing said coiled member in proper position on said strap.
