l Claim.

This invention relates to a buckle and has special reference to a slide buckle adapted to be mounted on a strap, band, or the like, for securing articles together or for the support of garments or other objects.

More particularly, this invention relates to a slide buckle for association with a strap comprising a pair of slidably engaged frames disposed in a face-to-face substantially parallel relation each having side bars and cross bars connecting the side bars for dening openings therethrough for receiving a strap, there being means for directing relative longitudinal movements of the frame with one cross bar of one of the frames co-operating with one of the cross bars of the other of the frames to clamp the strap threadable therebetween in adjusted positions upon relative longitudinal movement of the frames in one direction and a ringer piece on one of the frames manually movable to cause relativev longitudinal movements between the frames in the opposite direction to release the strap.

The device of the present invention may be adapted for use in various connections and, as a matter of fact, the construction may be employed with slight variations not departing from the spirit of this invention universally Where detachable connections are described.r Hereafter, and in the drawings, the device will be described and shown in its association with a strap for skates, books, and the like, although it is readily understood that the buckle may be employed with a strap for attachment to lingerie, for encircling the leg as a hose supporter, for use as a suspender, or for detachable engagement with garments of various characters. It is, of course, to be understood that various other uses may be mentioned and that this invention is not to be limited to any single specific use.

'Ihe buckle contemplated herein is adapted for use with a strap of leather, fabric, elastic, or any ilexible material, and the strap may vary materially in thickness. The clamping action is preferably obtained automatically by the tension applied to the strap and retained in its use in securing skates on shoes, various articles together in a bundle, or as a suspender, garter, or the like, and an adjustment of the buckle to loosen the strap may be made with little effort by moving manually a nger piece on o-ne of the frames.

As above stated, when tension is applied to the strap as in drawing up the strap to t the strap tightly around the shoe, in securing skates thereto, a relative longitudinal movement of the frame 'is obtained and this movement directs co-operating cross bars of the co-operating frames into engagement with each other to clamp the strap in position therebetween. This clamping engagement is held until a relative vlongitudinal movement between the frames in opposite directions is caused preferably by manual manipulation, one of the frames having a nger piece readily accessible for engagement.

In one form of the invention a iinger piece is accessible through the strap opening of one of the frames, the iinger piece being preferably formed integral with one cross bar of the other of the fra-mes and in the other form the nger piece is formed as a rolled free edge of one cross bar of one of the frames readily accessible for engagement to tilt the frames with respect to the normal plane of the strap to cause relative longitudinal movement between the frames in an opposite direction to release the strap,

O-ne of the objects of this invention is to provide a buckle having relatively slidable frame members of the type hereinabove described in which the 'strap threaded therethrough is automatically adjusted to a clamped position by a tension applied to the strap and is released from a clamped position by manual manipulation of a finger piece formed on one of the frames.

Another object of this invention is to provide a buckle having relatively slidable frame membersas hereinabove pointed out in which a nger piece secured to and extending from one of the frame members is accessible for movement to release the strap from a clamped position through the strap opening of the other oi the frames.

A further object of this invention is to provide a buckle having relatively s'lida'ble frame members of the type before described in which the strap is released from a clamped position by means of tilting a nger piece with respect to the normal plane of the strap to cause relative longitudinal movement between the frames.

It is also an object of this invention to provide a buckle having relatively slidable frame members of the character indicated above in which the construction is relatively inexpensive to manufacture, is durable, and is simple in construction, in threading, and in manipulation.

Other objects and advantages of this invention will be hereinafter more particularly pointed out and for a more complete understanding of the characteristic features of this invention reference may novr be had to the following description when taken together with the accompanying drawings, in which latter:

Fig. 12 is a View similar to Fig. 11 showing the strap in a released condition.

Referring now to the drawings and more particularly to Figs. l to 4, inclusive thereof, the construction therein shown as embodying the features of this invention comprises a pair of frame members I and II, the frame member I0 being substantially rectangular in shape and having spaced side bars I 2 and I3 connected by spaced cross bars I4 and I5 to define a strap opening. The frame Il is substantially rectangular in shape and has spaced side bars I3- and Il connected by spaced cross bars I8 and IS forming a strap opening.

The frame III is provided with opposed flanges 20 and 2l with ledges 22 and 23 extending respectively therefrom inwardly in a direction toward each other. The opposed flanges and ledges constitute opposed channels on the frame Il for receiving the side bars I8 and I'I of the frame II for directing relative longitudinal movements of the frames.

The cross bar I4 of the frame I0 is preferably inclined to provide an inclined strap-engaging face 24 extending between a rolled free edge 25 and an inturned ledge 23, the inturned ledge 2B defining the limit of movement of the frame II in one direction and the rolled free edge 25 presenting a fulcrum about which the strap may be pulled in applying tension thereto.

The frame I I is provided with an offset portion 2I which is preferably cut and deformed from the material thereof to provide the strap opening therein. The offset portion 21 co-operates with the inclined surface 24 to clamp a strap 28 in adjusted positions therebetween. A nger piece 29 is preferably formed integrally with the frame II and extends angularly relative to the normal plane of the frame in the direction of the opening of the frame IU so that the nger piece is accessible through that opening.

The frame I0 is provided with a looped end portion for receiving the free end of a strap threaded through the openings of the co-operating frames ID and II, there being a raised cross bar Ia spaced from the end of the frame I0 connecting extensions of the side bars I2 and I3.

One end of the strap 28 is looped permanently about the cross bar I of the frame Ill and the other free end of the strap 28 or a second strap is threaded through the opening of the frame I0 and between the offset portion 27 and the inclined strap-engaging face 24 of the frame I0. Tension is applied to the free end of the strap 28 over the rolled edge 25 to clamp the strap under tension in a desired adjusted position. When it is desired to release the tension on the strap, the strap is lifted to the position in Fig. 4 and the nger piece 29 is engaged by the thumb or finger and moved in an opposite direction to that of the tensioning movement. The strap is thus released by manual manipulation.

Referring now more particularly to Figs. 5 and 6 of the drawings, the buckle shown therein comprises a pair of frame members 30 and 3l, the frame 33 being substantially rectangular in shape and having spaced side bars 32 connected by spaced cross bars 33 and 34 to form a strap opening. The frame 3l is likewise substantially rectangular in shape and comprises a pair of spaced side bars 35 connected by spaced cross bars 36 and 31.

The frame 3U is provided with opposed anges .'ia with ledges 30h extending therefrom inwardly in a direction toward each other. The opposed anges and ledges constitute opposed channels on the frame 30 for receiving the side bars 35 of the frame 3l for directing relative longitudinal movements of the frames.

The cross bar 33 of the frame 30 is provided with rolled edges 38 and 39 with the under surface therebetween being inclined to form an inclined strap-engaging face 40. The frame 3I is provided with an offset portion 4I preferably cut and deformed from the material thereof to form the strap opening of the frame 3|.

A pair of ears 42 are bent downwardly and thereafter in a direction inwardly toward each other from the opposed ledges 30h to form a split cross bar extending laterally of the frame 3U. A metal attachment 43 is looped about the cross bar 42, the opposed sides of the attachment extending beyond the cross bar to receive in a clamped relation therebetween the end of a strap 44. In the particular attachment shown, prongs 45 are cut and deformedl from the material of one of the sides of the metal attachment to penetrate the material of the strap and extend through perforations in the other side of the metal attachment to be bent thereover for securing thc end of the strap 44 against displacement therefrom.

The free end 44a of the strap is passed through the opening of the frame 3l and between the offset portion 4I thereof and the inclined strapengaging face 4U of the frame 30. Tension is applied to the free end of the strap in pulling the strap about the rolled edge 39 to obtain relative longitudinal movement of the frames in one direction to clamp the strap in a xed position. The free end is thereafter passed under the cross bar 34 and the buckle is in a clamped position relative to the strap with the free end being held against creeping.

In order to release the strap from its clamped position, the free end of the strap is removed from beneath the cross bar 34 and the rolled edge 33 is engaged by the nger, as shown in Fig. 6,

c denne a strap opening.

to tilt the frame out of the normal plane of the strap about an axis provided by the cross bar 42 to cause relative longitudinal movement between the frames in a direction opposite to the clamping movement.

Referring now more particularly to Figs'. '7, 8, and 9 of the drawings, the construction therein shown as embodying the features of this invention comprises a pair of frame members 46 and lll', the frame member 46 being substantially rectangular in shape having spaced side bars 48 and i9 connected by spaced crossl bars 50 and 5I to The frame 41 is substantially rectangular in shape and has spaced side bars 52 connected by spaced cross bars 53 and 54 to form a strap opening.

The frame 46 is provided with opposed iianges 55 having ledges 56 extend-ing therefrom inwardly in a direction towardeach other. The opposed flanges and ledges constitute opposed channels on the frame 46 for directing relative longitudinal movements of the frames.

The cross bar 50 of the frame 45 is preferably inclined to provide an inclined strap-engaging face 51 extending from a rolled free edge 58. The opposite edge of the strap-engaging face is cut away to form a slot 59 through which an extension 50 of the cross bar 53 of the frame 4l passes. The end of the extension 60 is upturned to provide a nger piece [il for manually operating the frame 4l to release the strap from a clamped position.

A metal attachment 62 has a looped portion extending about the cross bar the opposed sides being spaced to receive therebetween one end of a strap 63. Ears 64 are cut and deformed from the material of one side of the metal attachment to penetrate the material of the strap and pass through apertures in the opposed side of the metal attachment to be bent thereover for preventing displacement of the strap 63 therefrom.

The free end of the strap is threaded through the opening in the frame 41 and between an onset portion 55 thereof and the inclined strapengaging face 5'! of the frame 46. Tension is applied to the free end of the strap 63 over the rolled edge 58 to clamp the strap under tension in a desired adjusted position. The loose end 63a of the strap is thereafter inserted underneath opposed ears 66 formed from the material of the metal attachment and directed inwardly in a direction toward each other in a spaced relation from the metal attachment.

When it is desired to release the tension on the strap the nger piece 6l is engaged by the thumb or finger and moved in a direction opposite to that of the tensioning movement. The strap is thus released by manual manipulation for further adjustment or removal.

Referring now more particularly to Figs. 10, 11, and 12 of the drawings, the buckle therein shown comprises a pair of frame members 6'! and 68, the frame 6l comprising a pair of looped portions 69 and 1l] connected by side bars 'Il and 12. The side bars 'H and 12 areconnected by a cross bar '13 which is depressed below the normal plane of the frame. Ledges 14 are formed on the side bars H and 'l2 and extend inwardly in a direction toward each other in a spaced relation from the side bars 1| and 12 to form opposed channels. The looped portion is raised above the normal plane of the frame and provides an opening for receiving the loose end of a strap 15. The looped portion 69 is provided with an inclined strap-engaging portion 16 on the under side of the material bounding the loop opening.

The frame 68 has a substantially flat end portion 'Il for engaging the opposed channels formed by the ledges 'f4 and side bars 1l and 'i2 to direct relative longitudinal movements of the frames. The opposite end 'I8 of the frame 68 is inclined in the direction of the inclined face 16 of the frame 61, and, when in a clamped position, the end extends beyond the end of the cross bar 69. An opening 79 is formed intermediate the inclined portion I8 and the substantially flat portion 11, and the material of the opening 'I9 is deformed to provide a strapengaging ledge 80.

A metal attachment 8l is provided with a looped portion intermediate its ends, the ends being extended in a face-to-face position to receive therebetween the fixed end a of the strap T5. The end 15a o-f the strap is fixedly secured to the metal attachment by means. of a rivet 82 extending through the strap and through an aperture in the opposed ends of the metal attachment.

The free end of the strap 'l5 is passed through the opening 'i9 and thereafter between the strapengaging face 16 and the strap-engaging ledge 80 of the respective frames 61 and 68. Tension is applied to the free end of the strap to clamp the strap under tension in a desired adjusted position as shown in Fig. ll. The free end of the strap is thereafter inserted through the loop of the frame underneath the bar 10 for use. When it is desired to release the tension on the strap, the extending portion of the cross bar 18 of the frame 68 is engaged by the thumb or nger andA is moved in an opposite direction to that of the tensioning movement.

While several embodiments of this invention are herein shown and described, it is to be understood that various modifications thereof may be apparent to those skilled in the art without departing from the spirit and scope of this invention and, therefore, the same is only to be limited by the scope of the prior art and the appended claim.
