Jan. 29, 1963 M. SCHWARTZ ADJUSTING STRAP BUCKLE Filed Feb. 9, 1961 INVENTOR. BY Marcus Schwarrz ATTORNEY 3,075,268 ADJUSTING STRAP BUCKLE Marcus Schwartz, Kew Garden Hills, N.Y., assignor to S. & S. Industries, Inc, New York, N.Y., a corporation Filed Feb. 9, 1961, Scr. No. 83,117 3 Claims. (Cl. 2420) This invention relates in general to a strap buckle, and more specifically to an improvement in garment buckles for rendering garment straps readily adjustable to the body of the wearer, and for positively securing the strap in the adjusted position. The buckle to which the instant invention pertains is that class of buckle associated with straps, bands, ribbons or the like for supporting and adjusting garments, such as slips, brassieres, undergarments of various kinds, harnesses and the like to the body of a person.

Heretofore, it had been customary to employ a rigid metallic buckle having a frame formed with end members interconnected by a plurality of cross bars, one of which has looped thereover the fixed strap of the garment and the others of which have threaded or laced thereover the free end of the adjustable strap, e.g. the shoulder strap. In the known conventional type of strap buckle the free end of the adjustable strap was merely looped about one cross bar and doubled over onto itself to adjust the strap to the required length, and the strap then held fast by lacing the doubled over portion of the strap over one cross bar and under another. Consequently, in the buckles of the known constructions the adjusted strap was held merely by the frictional force or" the lacing arrangement of the strap over and under opposite crossbars. Thus in the event of an exaggerated body movement, or in the event the strap is thin, shiny or worn, the mere lacing of the strap in the known manner over the cross bars of the buckle is insufficient to prevent slippage. Consequently, the known buckles under certain conditions proved troublesome, requiring the wearer to either endure the uncomfortable feeling of a mal-adjusted garment, which is particularly annoying if the garment is an undergarment, or else be annoyed by a continual need for readjusting'the strap to take up the unavoidable slippage.

Therefore an object of this invention is to provide in a buckle of the type described an improvement which will effect a positive gripping of the strap in the adjusted position and thus minimize slippage of the strap due to either exaggerated body movements or worn or shiny straps.

Another object is to provide an improved strap buckle in which the positive gripping action of the buckle on the strap is rendered more positive as the stresses tending to produce slippage of the strap is increased.

Another object is to provide an improved strap buckle that is relatively simple in construction, inexpensive to produce, and which is positive in operation.

Other objects, features and advantages will become more readily apparent when considered in view of the description and drawings in which:

FIG. 1 is a detail view of the buckle incorporating the improvement of this invention.

FIG. 2 is a perspective view illustrating the buckle as applied to a garment, e.g. a slip or brassiere in which the straps are not under a stress.

FIG. 3 is a right end view of FIG. 2, with the buckle shown in section.

FIG. 4 is a perspective view of the buckle as applied to a garment illustrating the buckle as it appear when the garment strap is under a stress.

FIG. 5 is a right end view of FIG. 4, with the buckle shown in section.

. 3,075,268 Patented Jan. 29, 1963 Referring to the drawings, FIG. 1 illustrates a strap buckle 10 in accordance with this invention. It comprises essentially a frame having a pair of side members 11 and 12 interconnected by end cross member 13 at one end thereof, and over which the fixed strap 14 of a garment 15 is adapted to be looped. Projections 16 may extend inwardly from both side members to serve as posi tioning means for the strap 14. A second cross member 17 is extended between the side members intermediate the ends thereof, and the end portions 11A, 12A of the respective side members 11, 12 are turned inwardly to define with cross member 17 a T-shape slot 18.

in accordance with this invention a flexible cross bar 19 is extended between the side members at a position intermediate cross members 11 and 17. As shown the bar 19 is arcuate in shape and it is normally bowed in the direction of cross member 13. The important aspect of this invention is that the bar 19 is adapted to flex between the stressed strap position as shown in FIG. 4 and the unstressed strap position as shown in FIG. 2.

According to this invention the adjustable strap 20, which has one end (not shown) fixed to the back of the garment, e.g. a slip or brassiere, in a suitable manner,

and has its free end 20A looped about the flexible bar 19 which is reversed upon itself as seen in FIGS. 2 to 5. Thus the strap i adjusted to the wearer simply by taking up or letting out onthe free end of the strap 20. To fasten the free end 26A of the adjustable strap 20 in the desired adjusted position the doubled over strap portion is laced over cross member 1'7 and under inturned ends 11A, 12A. This lacing frictionally secures the straps in adjusted position, as in the conventionaltype buckles.

However, in the arrangement described it will be noted that any tendency of the strap 20* to slip, when in the laced position thereof, due to exaggerated body movement, or too worn, thin or shiny smooth straps when excessively stressed, is resisted due to the flexing action of the bar 19 about which strap 20 is looped. As shown in FIGS. 4 and 5, when the strap is placed in tension or otherwise stressed, it causes bari9 to flex in the nature of a toggle. That is, the arcuate portion of the bar is" flexed through its dead center position. Thus a positive gripping of the strap is attained by the flexing action of bar 19 as the strap is stressed. The buckle arrangement is such that as the bar 19 flexes from its normal bowed position, as shown in FIGS. 2 and 3, to its stressed position of FIGS. 4 and 5, the strap portion looped between cross members 17 and 19 become firmly wedged therebetween. Thus it will be noted that the more strap 20 is stressed, the greater will be the force exerted by the flexible bar 19 against bar 17 and the strap 29 wedged therebetween due to the toggle-like action of flexing bar 19. Thus the positive gripping action of the strap of the buckle construction herein described prohibits any tendency of the strap 20 to slip. Consequently a garment equipped with a strap buckle described is less likely to become maladjusted.

In accordance with this invention the buckle is preferably formed of a plastic material such as Delrin or the like. Thus, by merely sizing the shape and thickness of the respective buckle component parts, the respective components can be rendered as rigid or flexible as required to effect the operation of the buckle as herein described.

It is common practice in the brassiere and undergarment industries to use different types and thickness of materials for garment straps. In order that these various materials used for garment straps be properly secured without slippage in the strap buckles heretofore known, it has always been necessary to maintain a large buckle inventory of a great many different kinds of buckles, in

amazes order to accommodate the different kinds of materials. For example garment straps are manufactured in approximately four widths, such as /z", A" and /8", and may be made from single ply ribbon, double ply cloth, laminated cloth, 'i.e. two materials laminated together, stitched nylon, satin and many other materials, all having different thicknesses. For each thickness of these materials 'a dilferent size slot opening is required in the buckle so that the buckle could work without slippage. Thus the buckles had to be stocked according to both width and size of slot in order to accommodate the present varieties of straps. Thus complete inventories of such buckles would consume much of the manufacturers space, time and money.

With the instant invention the wedging or toggle like action of the flexible bar 19'greatly reduces the need of stocking buckles with different slot sizes of any given width since the toggle action permits the buckle to be applicable with straps or varying thickness. Thus the instant buckle 'is readily adapted to securely fasten without slippage and with equal facility straps of varying thicknesses. Thus the heretofore large inventories of buckles, heretofore required, can be greatly reduced, thereby affording a garment manufacturer substantial savings in time, moneyand space.

While the instant invention has been disclosed with reference to a particular embodiment thereof, it is to be appreciated that the invention is not to be taken as limited to all of the details thereof as modifications and variations thereof may be made without departing from the spirit or scope of the invention.
