BUCKLE FOR SAFETY BELTS Filed April 25, 1962 2 sheets-sheet 2 d nar.

Uf f INVENTOR.

SOL WEXLER United States Patent Office ll Patented Jan. 21, 1964 York Filed Apr. 25, 1952, Ser. No. 190,056 2 Claims. (Cl. 24-230) This invention relates generally to safety belts and more particularly to a buckle construction for safety belts.

A principal object of the present invention is to provide a buckle construction that is relatively free from the possibility of accidental or inertia-operated unlocking.

Another object of the invention is to provide a buckle construction wherein the release lever does not function to maintain the two buckle components in engagement.

Still another obj'ect of the invention is to provide a buckle construction wherein the cam members function to hold the two buckle components together.

specific object of the invention is to provide a single spring construction for biasing the cam members to a position holding the buckle components in engagement.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

ln the accompanying drawings forming a material part of this disclosure:

FIG. l is a top plan view of a buckle construction embodying my invention shown disassembled.

FIG. 2 is a part elevational and part sectional view through the longitudinal center of the buckle construction in assembled condition.

FG. 3 is a cross-sectional view taken on the line 3 3 of FIG. 2.

FIG. 4 is a view similar to FIG. 2 but with the release lever moved to release position and the buckle components partially disengaged.

FlG. 5 is a perspective view of the cam assembly.

FIG. 6 is a cross-sectional view taken on the line 5-5 of FIG. 4.

lTlG. 7 is a perspective view of the biasing means for the cam assembly.

FIG. 8 is a bottom plan view of one of the buckle components forming part of the invention.

Referring in detail to the drawings, a buckle construction embodying my invention is shown in FlG. 2 and desi gnated generally by the reference numeral lil. The buckle construction lil comprises broadly a buckle component or coupling member l2 and a buckle component or coupling member i4 for fastening the ends i6 and i5 of a belt 29 to each other.

The buckle component i4 is a flat metal rectangular plate 22 formed along one long edge with an elongated closed slot 24 for receiving the looped end 18 of the belt 2rd. Apair of spaced openings 26, 26 is formed along the other long edge of the plate to receive parts of the buckle component 12.

With particular reference to FiGS. 2 and 3, the buckle component l2 comprises a frame including a flat rectangular metal base 28 and parallel opstanding side flanges Eil, 3i?. The base 23 is provided with upwardly bulged portions 32, 32 adapted to fit in openings 26, 26 of buckle component i4. The positioninf7 of the openings 26, 26 in the component i4 and the formed portions 32, 32 on component l2 may be reversed if desired. The surfaces 34, 34- cf the bulging portions 32, 32 are slanted with respect to a normal to the base 28 at an angle of twenty to twenty-live degrees, if the members are to be left in their original condition established by the forming dies.

The openings 26, 26 in the buckle component Vi4 are beveled from both sides along the edges 36, 36 so that these surfaces will conform to the surfaces 34, 34 regardless of the orientation in which the component i4 is shoved into enga-gement with the component l2.

The flanges Sil, Si? provide for the mounting of a cylindrical shaft 38, the hexagonal head 49 of the shaft at one end being received in the similarly-shaped opening in the adjacent flange 33 to assure nonrotative positioning of the shaft with respect to the frame of the buckle. The shaft is formed with an elongated closed slot 42.

A pair of camming levers 44, 44 is rotatably mounted on the shaft 33 at its ends, the shaft passing loosely through holes 45, 4S in the levers. The shape and dimensions of the camming levers are selected so that a small amount of clearance is provided for the belt buckle component 14 when itis inserted in the fully engaged positions shown in FIG. 2. The purpose of the camming levers y44, `44 is to maintain the bulging portions 32, 32 of component d2 in locking position in the openings 26, 26 in component i4.

ylt will be noted from FIG. 3, that the flanges 30, 30 of the frame, the camming levers 44, 44 and the bulging portions 32, 32 of component l2 are positioned in such a manner that the camming levers 44, 44 are as close as possible to the flanges Btl, 3d and the bulging portions 32, 32 are as close as practical to the camming levers 44, 44, respectively.

T he buckle `component l2 includes a release lever designated generally at 4E. e release lever consists of a compound curved metal rectangular plate 5G formed with inwardly extending flanges 52, 52 along its lon-g edges, the flanges at one end terminating in inwardly extending perforated ears 5 4, E4 forming bearings for bushings 55 through which the ends of shaft 38 pass to the flanges 3G, Sil. The other end of the plate Sil is turned outwardly abruptly forming a handle 56 for manipulating the lever. lhe short edge 7@ of the lever at the end bearing the ears 54, 54 presses against the adjacent long edges of the camming levers 44, 44. Metal washers oil, d@ are mounted on the shaft 38 between the camming levers and the perforated ears 54, 54.

The present invention contemplates a single elongated torsion spring device 62 for biasing the camming levers 44, 44 with respect to the release lever 48 and shaft 3S. The spring construction 62 includes a pair of coiled spring portions 64, 64 connected by a length of wire 66. The spring device 62 is sleeved around the shaft 38 with its end portions 64, 64 adjacent the camming levers 44, 44 and with its connecting Wire 66 inserted through the slot 42 of the shaft and extending along the interior of the shaft. The ends 68 of the spring device are offset from the outermost convolution and are hooked around the camming levers 44, 44 adjacent the outer ends therof. The net result of this arrangement of the spring device is that the spring device is held in a relationship which is xed with respect to the shaft and to the frame of the buckle as a result of the nonrotative mounting of the shaft 33. lThe camming levers 44, 44 are biased in such a direction that said levers engage the edge itl of the release lever 4S and urge the lever toward closed position.

Referring to IFIG. 4, the release of the buckle involves the movement of the lever 48 in a clockwise direction to the point that the camming levers 44, 44 are driven in a similar direction a sutlicient distance to permit the coupling member 14 to rise over the bulging portions 32, 32 and thereby be free to be Withdrawn. The reengagement of the coupling members takes place as shown in lFlG. 2. As the coupling member 14 is pushed to the left, the camming levers 44, 44 are rotated by the force applied by the end of the coupling member 14. The movement of the camming levers a suflicient distance to permit the inser- 3 tion of the buckle component 1.4 taires place without any corresponding movement of the release lever 4S, and the engagement is opposed only by the spring 62.

A knurled pin 76 is slidably mounted in a cutout portion 7S formed in the base 23 and is adapted to receive the end of the belt 20 therearound. When the release lever 43 is in uppermost moved position the belt may be moved with respect to the pin for adjusting the effective length of the belt. When the lever 4S is returned to normal position, the lever clamps the belt between the pin and the edge of the cutout portion.

While l have illustrated and described the preferred embodiment of my invention, it is to -be understood that I do not limit myself to the precise construction herein disclosed and that various changes and modiiications may be made Within the scope of the invention as deiined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent 1.
