(Cl. 2li-236) Claims.

This invention relates to buckles and more particularly to buckles for wearing apparel such as belts.

An object of the present invention is to provide an improved two-member buckle of the type wherein the members are provided with parts adapted to telescope, into one another and engage in interlocking position.

A still further object is a buckle which is simple in construction and effective in operation and so manufactured that upon telescoping of the members they will automatically be positioned in proper relative relation as well as interlock and remain interlocked until manually released.

Other objects will be in part obvious and in part pointed out more in detail hereinafter.

The invention accordingly consists in the features of construction, combination of elements, andarrangement of parts which will be exemplified in the construction hereafter set forth and the scope of the application of which will be indicated in the appended claims.

In the accompanying drawing:

Figure 1 is a front view of the buckle as applied to the ends of a belt;

Fig. 2 is a rear view of the assembled buckle with the parts in interlocking engagement;

Fig. 3 is a sectional view taken on the line 3 3 of Fig. 2;

Fig. 4 is a side view with a portion of one member broken away to show the parts in interlocking engagement;

Figs. 5 and 6 are perspective views of the buckle members; and

Fig. 7 is a view showing the relative positions of the parts as they are moved into interlocking engagement.

Referring to the drawing, the buckle comprises generally a pair of members A and B having cooperating parts for maintaining same in proper relative position and to detachably interlock them together. 'Ihe members A and B may be of any desired shape and configuration and are preferably formed from stampings of sheet metal.

More particularly, the member A comprises a rectangular front plate I Il having parallel side flanges I2 extending rearwardly from and at right angles to the side edges thereof and coextensive therewith. The member A further includes a pair of anges I4 extendinginwardly from and at right angles to the rear edges of theflanges I2; the flanges thus being spaced rearwardly of and parallel to the front plate `A to define suitable guideways therewith. As best seen in Fig. 6,

each flange I4 extends from the leading edge of the member B substantially the full length thereof, but is reduced in width intermediate the ends thereof to provide inner and outer guide members I5 and Iii; the inner guide I6 cooperating with suitable positioning means on the member A and the outer guides I5 with interlocking means carried by the member B. The trailing edges of the guides I5 further function as locking shoulders, for reasons hereinafter apparent.

`The member B also comprises a rectangular front plate I8 having parallel side flanges 20 extending rearwardly from and at right angles to the side edges thereof and coextensive therewith. In accordance with the invention herein, the front plate I 3 and side flanges 2li of member B are adapted to lie in the same plane as and be coextensive with the front plate I0 and side flanges I2 of member A when the buckle is closed, thus giving the buckle the appearance of a one-piece member.

To accomplish the proper positioning of the members relative to one another, the leading edge of the front plate I8 of member B is turned rearwardly to define an end facing shoulder or stop 22 having a depth equal to the thickness of plate I0 of member A and adapted to abut against the leading edge thereof when the buckle is closed.

` The shoulder 22 further functions to offset out of the plane of the plate I8 suitable positioning means, generally designated as I9, including a pair of arms 24 extending outwardly from the rear edge of shoulder 22 adjacent the opposite ends thereof. Each of the arms 24 includes an vinner -camming portion 28 extending obliquely and rearwardly from the shoulder 22, and the intersection of the camming portion 28 and the shoulder 22 defines an upwardly facing inner positioning shoulder 2l adap-ted to abut against the rear face of the plate I0 when the buckles are closed. Outwardly of the camming portions 28 the arms 24 each includes a fulcrum 30, and the angle` and length of the camming portions 28 are such that the fulcrums 3i) are spaced rearwardly of shoulder 21 a distance slightly greater than the spacing between the plate I0 and the guide members I6 of the buckle member A.

To complete the positioning means I9 of the member B, the outer extremities of the arms 24 are interconnected by a transverse cross bar 32 having its leading edge bent forwardly to provide a positioning lip 3Q; the length of the lip being such that the outermost edge thereof functions as a second or outer positioning shoulder 36 spaced from and lying in substantially the same plane as the inner shoulder 2l at the other extremity of the positioning means.

With the positioning means so constructed, when the buckle members A and B are moved into closing position, the positioning means i9 will readily enter into the guideways of the member A and move forwardly until the leading edge of member A abuts against the camming portion 28 of the positioning means I9, as seen in Fig. 7. Thereafter, upon further movement towards closed position, the fulcrums 30 will be urged downwardly and into contact with the inner faces of the guide members I6 and the outer positioning shoulder 36 of the positioning lip 34- into abutting contact with the rear face of plate l0.

Due to the fact that the fulcrums 3l] are normally spaced from the plane of the inner and outer positioning shoulders 21 and 36, further movement of the members into closed position will result in a bending or springing of the camming portions 28, due to the natural resiliency of the metal, in a counterclockwise direction, as viewed in Figs. 3 and 4, about the fulcrums 3i). Due to rthis bending, when the leading edge of the member A abuts against the end facing shoulder or stop 22 of the member B, the front plates lil and i3 will lie in the same plane with the inner and outer positioning shoulders 21 and 36 abutting the rear face of plate IIJ and the fulcrurns 353 engaging the guides l5. Moreover, as the shoulders 27 and 35 and fulcrums 30 will' all be under tension and in frictional engagement with the cooperating parts of the member B, the buckle members will thus be positively maintained in .proper relative position.

As the frictional engagement will not be sufhcient to maintain the parts in locked position, there is further arranged on the member B suitable locking means including a tongue 40 centrally positioned and extending outwardly and Vat an oblique rearward angle from the rear edge of the end facing shoulder 22. The width of the tongue 'lil is narrower than the spacing between the guides iS but carries on the outer end thereof transversely extending locking arms 42 of greater width than the guides I5, but of less width than the spacing between guides I6. The rear edge of each arm i2 is turned forwardly through slightly more than ninety degrees to provide a locking shoulder 44 adapted to be positioned behind the locking shoulder I1 of the guides Iii and thus interlock the members together. Toso position the locking shoulders 44, the angle of the tongue di) is such that the plane of the locking arms i2 is spaced rearwardly of the plane of the fulcrums 35i of the positioning arms, and thus as the parts are assembled, upon moving the locking arms 132 underneath the guides l5 the tongue 40 will be sprung forwardly towards the front plate il] of the member A until the shoulders :M moveV beyond the locking shoulders il of the guides I4, whereupon the tongue will spring them rearwardly and behind same, and due to the slight angle of the locking shouldei` fifi a positive locking will result. To limit the outward springing of the tongue, the forward edges of the locking shoulders 413 may be turned at right angles to provide suitable restraining shoulders d6 which will engage the forward faces of the guides it and thus maintain the locking arms in proper locking position.

Y In order to release the parts, it is'only necessary'to press forwardly on the center portion of the tongue 40 to release the shoulders 44 from behind the shoulders Il', whereupon the parts may be readily separated.

As usual, the trailing edges of each of the members A and B may have pivotally mounted in the side anges thereof a suitable clamping member 48 adapted to secure each member to one end of a belt webbing C. As the clamping members are of usual and well known construction and form no part of the invention herein, no further description thereof will be given.

As many changes could -be made in the above construction and many apparently widely different embodiments of this invention could be made vwithout departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the language used in the following claims is intended to cover all of the generic and specific features of the invention herein described and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
