Jan. 18, 1949. D. CANOVSKY WRIST BAND Filed Aug. 30, 1944 2 T, 1, 28 INVENTOR.

I fiawd 6011mm :4 2s 27 flQWM QM! A TTOR/YEXS' Patented Jan. 18, 1949 UNITED STATES PATENT OFFICE WB'IS AND DavidCanovsky,-Ne w Orleans, La. Application August 30, 1944; Serial No. 551,819 2 Claims. (01. 224 -4) The invention relates to bands to be used to hold ornamental or useful objects orinstruments on the wrist of a wearer. It is an object of the invention to provide an expansible andadjustable band for the. purpose that may be both placed in position and removed with the utmost facility.

It is a further object to provide a device of this character of great simplicity and therefore cheap. to manufacture.

Further objects of the invention are to provide a device having no frail parts which are liable to breakage; of pleasing appearance; and having provision for locking against accidental displacement.

Further objects will appear from the following description when read in connection with the accompanying drawings showing an illustrative embodiment of the invention, and wherein:

Figure 1 is a side elevation of the band of the invention as applied to a wrist watch and in open position;

Fig. 2 is a like view of the device showing the relation of the parts when in position upon a wrist;

Fig. 3 is a side elevation of the structure of Fig. 2 seen from the left of said figure;

Fig. 4 is a detail section on line 4-4 of Fig. 3 drawn to an enlarged scale; and

Figs. 5 and 6 are detail sections on the corresponding section lines of Fig. 4.

As shown the device is applied to a wrist watch although it should be understood instead of the wrist watch the device may be a plain ornamental band used as a bracelet or an ornamental object of a bracelet may be held on the wrist in the place of the wrist watch ll] indicated in the drawing. Furthermore, it will be understood that any instrument which it is desired to carry upon the wrist for convenient observation may be retained thereon by a band of the invention.

As shown the band comprises two portions I I, I2, the portion II being formed with a plurality of openings l3 and as carrying at its end a traveller l4 pivoted in a loop l5 formed of the material of the band. To coact with the openings $3 to retain the band in adjusted position upon the wrist of the user, the portion I2 is shown as having directly pivoted thereon a hook member IE retained by the loop f1 similar to the loop l5 and formed from the material of the band, as clearly shown in Figure 4.

The hook I6 is very simply formed and comprises a single piece of wire having its ends entering the loop H at l8, l9 and, freely revoluble therein. The portions adjacent the ends 18, 1.9 are shown as integrally related to said end portions and as meeting at 20 in the form of a closed bis t. wh c i t is bent i t t n gral ook end portion 2 I. Said hook end may be of various forms but desirably is in the form of a cam open hook and as having the portion 22, Figure a, at such an angle to the meeting portionsthat when the deviceis to be removed from .the wrist a mere contraction of the band will cause the portion .22 to cam against the opposite side of the opening and release the hook.

To retain the hook H; in adjusted position, there is shown a second similar hook 23 having its ends engaged in a tubular member 241 together with the portion 25 of a traveller member, which traveller member surrounds and is freely slidable on the band portion H carying a roller tubular member 26.

When the device is placed upon the wrist and the hook I6 is engaged in an opening the traveler 24 may be freely moved to the position shown in Figure 4 and the hook 23 may be engaged in an opening adjacent to that in which the hook I6 has been already placed, the hook 23 overlapping the hook It in the position shown in Figure 4. So locked the band cannot be accidentally unhooked from the wrist of the wearer. For ordinary sedentary or desk use the locking hook is unnecessary and may be omitted.

To cause the hook 23 to lock itself when slid along the band there is shown a spiral spring anchored at the end 28 to the shank of the hook 23 and at'an end 29 in the tubular member 24, the spring biased to press the hook 23 toward. the band. i The simplicity of the operation of the device will be apparent from the above description. When the parts are in the position shown in Figure 4, upon the wrist of a wearer, movement of the

idler

26, 25, .26 toward the band l2 will cause the hook 23 to cam out of its engaged opening in the manner already described for hook 22. It may then be lifted against the tension of the spring 21 by the thumb of the user and slid away to the position shown in Figure l, in which figure the hook is shown as moved over into open position as though the spring 21 were absent and it may be omitted.

With the locking hook out of commission a slide closing movement of the band will cam the hook 22 out of its opening to be lifted by a forefinger of the user and swung to the position of Figure 1 whereupon the band may be opened to a position enabling the band to be removed by slipping over the hand of the user.

It will be understood that the traveller I4 is provided for the purpose usual in devices of this character of providing a free separation of the ends of the band when being adjusted to position.

Minor changes may be made in the physical embodiment of the invention within the scope of the appended claims without departing from the spirit thereof.

1 claim:

1. A Wrist watch band comprising, in combinaiton: band members each having an end for pivotal connection with a watch case; means associating the one of the remaining ends for free sliding movement upon the other thereof; said one band formed with a series of openings; the material of said other band, at its end formed into an integral loop; a hook member to enter a selected opening of the series formed of an integral wire comprising a pintle portion pivotally housed in said loop, separated shank portions converging to a hook end partaking of both of said initially separated portions, said hook portion formed with a cam exterior adjacent the hook terminus and adapted to lift the hook out of an engaged opening; whereby sliding action in one direction of said hook carrying band member relative to the remaining member automatically unhooks the band.

pivotally carried by said second traveller adapted to overlap said first named hook and engage an adjacent opening while the first-named hook is in holding position.
