2 Claims, 3 Drawing Figures COLLAPSIBLE SAW HORSE STAND BACKGROUND OF THE INVENTION 1. Field of the Invention This invention is in the field of collapsible stands.

2. Description of the Prior Art A representable sample of the prior art for collapsible stands and saw horse clamps is disclosed in the following U. S. Pat. Nos. 2,261,217 issued to C. H. Bond; 3,329,239 issued to R. L. Chesney; 3,055,453 issued to A. B. Vanyo; and 3,139,951 issued to W. Clayton. Many of the prior art stands for supporting a saw horse beam require a plurality of teeth to engage the beam therefore adding to the expense of stand manufacture. In addition, many of the prior art stands are not quickly collapsible nor are they easily erected. Disclosed herein is a collapsible saw horse stand which is relatively inexpensive as compared with the prior art devices and which may be quickly erected and collapsed in arelatively short period of time.

SUMMARY OF THE INVENTION One embodiment of the present invention is a collapsible stand for supporting an end of a saw horse beam comprising a horizontal bar upon which said end is restable, a firstmember having an L-shaped cross section with a mounting wall pivotally connected to said bar and a beam engaging wall extending perpendicularly from the mounting wall, a second memberhaving an L-shaped cross section with a mounting wall pivotally connected to the bar and a beam engaging wall extending perpendicularly therefrom, the beam engaging walls of the first and second member extend above the bar being spaced apart the approximate thickness of the beam, a first leg pivotally mounted to the bar outwardly of the first member and having a top end extending upwardly from the bar being abuttable against the beam engaging wall of the first member, a second leg pivotally mounted to the bar outwardly of the second member having a top end extendingupwardly from the bar being abuttable against the beam engaging wall of the second member, and means connected to the first leg and second leg below the bar being movable downwardly to force the bottom leg ends outwardly and the top ends of the first and second legs inwardly against the first and second members for clamping the beam therebetween.

It is an object of the present invention to provide a new and improved collapsible stand for supporting a saw horse beam.

It is a further object of the present invention to provide a collapsible saw horse stand which is relatively inexpensive to manufacture and quickly erectable and collapsible.

Related objects and advantages of the present invention will be apparent from the following description.

BRIEF DESCRIPTION OF THE DRAWING FIG. 1 is a perspective view of a saw horse beam supported by two stands incorporating the present invention.

FIG. 2 is a fragmentary enlarged view of the top portion of stand 13 of FIG. 1 with the beam removed thereform.

FIG. 3 is the same view as FIG. 2 only showing the beam engaged by the stand.

DESCRIPTION OF THE PREFERRED EMBODIMENT For the purposes of promoting an understanding of the principles of the invention, reference will now be made to the embodiment illustrated in the drawing and will nevertheless be understood that no limitation of the scope of the invention is thereby intended, such alterations and further modifications in the illustrated device, and such further applications of the principles of the invention as illustrated therein being contemplated as would normally occur to one skilled in the art to which the invention relates.

Referring now more particularly to the drawing, there is shown a collapsible saw horse 10 having an elongated beam 11 supported at either end by identical

collapsible stands

12 and 13. Stand 13 will now be described, it being'understood that an identical description applies to stand 12.

' Stand 13 has a horizontal bar 22 upon which the end of beam 11 is restable. A pair of

legs

14 and 15 are pivotally mounted to bar 22 respectively by

standard fastening devices

24 and 23. In addition, a pair of

members

32 and 27 are pivotally mounted to bar 22 being spaced apart the approximate thickness of beam 11.

Legs

14 and 15,

members

32 and 27 and bar 22 each have an L-shaped cross section composed of a pair of walls integrally joined together at right angles. Member 32 has a mounting wall 34 pivotally connected to bar 22 by fastening device 25. A beam engaging wall 33 extends perpendicularly from mounting wall 34. Likewise, member 27 has a mounting wall pivotally connected to bar 22 and a beam engaging wall extending perpendicularly from its mounting wall. The beam engaging walls of

members

32 and 27 extend above bar 22 in order to clamp beam 11.

Leg 14 is positioned near the end of bar 22 thereby being positioned outwardly of member 32. Likewise, leg 15 is positioned near the end of bar 22 thereby being positioned outwardly of member 27. Each leg has a top end extending upwardly from the bar which is abuttable against the beam engaging wall of its adjacent member. For example, the top edge of wall 28 of leg 14 abuts wall 33 of member 32 when the leg is pivoted so as to force member 32 against beam 11 as shown in FIG. 3. Suitable spacers, such as washers, are positioned between the legs and bar 22 so as to allow each leg to overlap the adjacent member. Fastening

devices

23, 24, 25 and 26 may be bolts which extend through the legs, members and bar being secured thereto by hexagonally shaped nuts positioned on the inward side of the bar. The wall of each leg mounted to the bar slidably contacts the walls of the members mounted to the bar. For example, wall 21 of leg 14 slidably contacts wall 34 of member 32 when the leg is pivoted from the position shown in FIG. 2 to the clamp engaging position shown in FIG. 3.

A pair of

braces

16 and 17 have outer ends pivotally mounted respectively by fastening

devices

18 and 19 to

legs

14 and 15. Braces l6 and 17 overlap each having an inner portion pivotally connected together by a conventional fastening device 35. To collapse the stand, the inner end of brace 16 is pulled upwardly in the direction of arrow 29 thereby forcing

legs

14 and 15 to respectively pivot in the direction of

arrows

30 and 31 thereby allowing beam 11 to be removed from the stand. To erect the stand, the inner end of brace 16 may be forced downwardly in a direction opposite of arrow 29 thereby causing the top ends of the legs to moveinwardly against

members

32 and 27 so as to clamp the beam between the members. As the top ends of the legs are pivoted inwardly, the bottom portions of the legs to which struts l6 and 17 are connected are pivoted outwardly. The inner end of member 16 is provided with an overlapping flange to abut the top surface of strut 17 so as to limit the downward movement of the strut when the stand is being erected. Many other being spaced apart the approximate thickness of said beam, said beam engaging walls having mutually facing smooth surfaces for engaging'said beam without pro- 1 jections extendinginto and marring said beam and without requiring any special locating indentations in t v saidbeam; afirst leg pivotally and swingablymounted f to saidbar outwardly of saidfirst member, said first leg abuttable against said beam engaging wall of said first means may be provided to limit the downward movement of the braces or struts. For example, brace 16 may be provided with a protruding portion which frictionally engages a complementary sized recess within brace 17.

Stands

12 and 13 are particularly useful to hold a two by four wood cross piece firmly in place without using any fastening devices for securing the beam. to the stands. The stand is quickly collapsible and therefore portable in'a short period of time. Likewise, the stand may be quickly erected. g 3
