Elsner, Burbank, Calif., assignor to C. J. W. Corporation, North Hollywood, Calif., a corporation of California Application August l11, 1947, Serial No. 767,875
8 Claims. (Cl. 224-170) a buckle whereby desired tautnessof a strap can be attained, whereby said taut ess will be retained, and whereby quick release of said tautness is effected for quick separation of the buckle parts.
Another object of the invention is to provide a buckle, as indicated, which embodies automatic strap gripping means effective to retain the strap under tension, whereby a simple pull on one end of the strap elfects further tensioning thereof, and whereby quick release of the strap is eiected and separation of the buckle parts made possible by a simple manual push on an element of. the buckle.
Another object of the invention is to provide, in a strap buckle, novel strap gripping means that is automatically effective for gripping a strap, automatically releases upon a pull on a free end of said strap, and is adapted to be manually re- '25 tion and easily disconnected therefrom, econom-V ical of manufacture, relatively simple, and of general superiority and serviceability.' ',lhe invention .also comprises novel details of construction and novel combinations and arrangements of parts, vwhich will more fully appear inthe course of the following description. However, the drawings merely show and the following description merely describes one embodiment of the present invention, and is given by way of illustration or example only.
In the drawings, like reference characters designate similar parts Vin the several views.
Fig. 1 is a side elevational View of the present buckle in operation connecting the ends of a strap.
roller means Ill mounted transversely of the frame at an intermediate part thereof for a loop II of said strap trained therearound so that the bight I2 of the'strap between its ends is below a free end I3 of the strap end 6, means I4 for gripping the strap to maintain tension thereof, and extension I5 of the latter means and engaged with the strap to urge the gripping means into strap gripping position, means I6 carried by the frame and having overstanding relation to the extension to protect the same against inadvertent movement, and means Il on the end 5 of the strap and having separable engagement with said frame.
The frame 9 is shown as formed of rod or heavy wire and is substantially rectangular having sides I8, an end I9, and a depressed end opposite to the latter. Theframe, of course, may be suitably formed in other Ways.
Fig. 2 is an enlarged top plan view of the buckle.
Fig. 3 is a longitudinal sectional View as taken on line 3-3 ofFig. 2.
The illustrated buckle is shown as connecting the ends 5 and 6 of a strap l to tightly and rmly hold a cargo load 8 while the same is being moved. The buckle comprises, generally, a frame 9.
, The roller means I0 comprises a transverse pin or axle 2| welded to the sides I8 intermediate the length of the frame and preferably somewhat nearer to the end I9, and a freely rotatable tube 22 on said pin, said tube thereby comprising a roller over which the loop II of the strap is trained. It will be noted that the bight I2 of the strap extends over the frame end 2U and then under and around roller 22.
Thegripping means I4 comprises a bracket which includes a plate or bar/23 arranged trans- `versely across the frame sides I8 and adjacent to the end 2t thereof, a pair of integral ears 24 of f said plate 23 extending upwardly on either side of the frame, a transverse pin 25 extending between the ears above said plate, and a preferably knurled eccentric roller 26 mounted on said pin to rock therearouncl. The plate 23 is welded to the frame in spaced relation to roller 22 and the free end I3 of the strap extends from the strap loop II and over said plate. The eccentric roller 26 is designed to effectively grip the strap end I3 between itself and said plate 23. n
In normal use, as indicated in Fig. l, the strap bight I2 is under tension to, thereby, exertra pull to the left (in Fig. 3) of the free strap end I3. This pull, when the knurled surface of eccentric 26 is frictionally in contact with the strap, causes rock ofthe latter to effect rmer gripping. Consequently, the stronger the tension on the strap bight I2the firmer the grip of the means I4 on the strap end I3.
'The extension I5 comprises a rigid lever -21 ori gripping roller 25 and extending toward the roller 22. The end of said lever is preferably curved at 28 for smooth, non-sagging impinging engagement with the upper surface 29 of that portion of the strap that extends between the rollers 22 and 26. The lever 2l is so angularly directed toward said surface 29 that the saine seeks the mentioned engagement. When the strap end i3 is slack, as shown by the dot-dash lines of Fig. 3, the roller;` 2li-- has` only slight or no contact with said strapJ end;` and by keeping said: end slack by a manual pressure on lever 2l, the effective length of the strap can be increased by either a pull on bight l2 or a pull in the opposite direction on the frame 9, the loop l I merely traveling over, theireeV roller 22, and by pulling on the free end I3, thef.
effective length of the strap can, be decreased.
Consequently, by training thest-rap about arload 8, connecting hooks 3B of the means i'l with the.
end IS of the frame, and simply pulling von the free end i3, the resultant tautness ofthe-strap` will ei'ect a straightening of the mentionedpor.
tion thereof between rollers 22 and 2&3. Said strap-portion.willlift the lever 21 tocause roller 2,6 to rock in,V aV strap-grippingv direction. The force oithepuillmay approach the strength of the strap and yet-upon release of the free end i3, the means` ltwill effectivelygrip the strap, it being evident that the eccentric grips stronger under greater tension,A
Whenrelease of the buckle is desired, a simple manual pushon lever 2 in the direction of arrow 3j will effect release rotation ofV eccentric 2t and, therefore, aslackingoii' of the strap. The power advantage obtained by the length oi'V lever 2l over any, tensionon the strap is readily effective to effectY thisrelease andthe same may be accomplished, in most instanoes, with the pressure of thethumb.
When the, strapissufciently slacked oir", the hooks 3i) may be disengaged from the buckle frame, the straplaid open, and the cargo loadremoved. In orderjto rnininfiize the friction between thelever 2l' andthe strap surface 2%, said'lever may, be, provided' with a roller, instead of the curvedportion 2.8. Suitable lugs, struck from the lever, may serve to mount said roller.
In use, when moving a cargo load, the lever may inadvertently encounter a posta hatch frame, etc. and be inadvertently depressed to effect spillage of the cargo load; To obviate this occurring, the .means,l6', comprising a rod or wire 3,2 weldedtothe frame, is provided in overstand'- ingrelationto lsaid lever so as to protect the saine. The means I6 also serves to limit the outer movement oithelever 2l.
Whilev I have illustrated and described what Ivnowi regard as theY preferred embodiment of my invention, the construction is, of course, subject to modifications without departing from the spirit andscope of my invention. I, therefore, do not wish torestrict myself to the particularformvof construction'illustrated and described; but desire to avail myself of all modications that may fall within the scope of the appended claims.
Having thus described my invention, what I claim and desireA to secure by Letters Patent is: l. A, buckle for. connecting the' ends of a strap c omprisinga frame, a roller mounted transversely in the frame, one end of the strap being trained oversaid-roller and doubled back in the direction of. the,- bight ofV the strap` to. form afreeA end, Wedging means carried by said frame in spaced relation to the roller andioperable togrip said free end intermediate its length, an unsupported portion of said free end r of the strap extending between the roller and the wedging means, an extension onrsaid wedgingmeansdirected to impinge on'said unsupported portion and held by the latter strap portion, when the same is taut, to hold the wedgin-g means in gripping relation with the strap, and means on the other end of the strap having separable connection with the frame.
