Abstract
ABSTRACT OF THE DISCLOSURE
A collapsible saw-horse is disclosed, comprising a beam and two frames extending side by side from the underside and longitudinally of the beam, and each forming a pair of legs for supporting the beam. Each frame consists of a single bent tubular member defining two upright leg portions and an intermediate bight portion at the lower end of the leg portions. The upper ends of the leg portions are bent back and inserted within brackets secured to the underside of the beam. One frame is rigidly secured to the brackets by screws extending through the brackets to take a collapsed position parallel to the first frame and an operative beam-supporting position diverging from the first frame. A pair of pivoted toggle arms link the two frames to prevent the pivotable frame from spreading beyond a predetermined limit angle with respect to the fixed frame.

Thr~ tran~versely-orlent~d and longitudinally ~paced-apart brscket~ 7 escure each o~ the frameo 3 and 4 to the bs~m 2.
Each breckat 7 1~ Pormed with a flat central portlon 7~
and two out~urdly and downwardly curved flsnge portione 7". Oracketo 7 ~re each rigidly ~ecured to b0am 2 by a head bolt ~ flnd nut 9, ~ho~n in Fig. 4. Nut 9 i8 prevented ~rom loosening because it fits between ths two portiong 7"' connecting respectlvo portion~ 7~ to central portion 7'.
Flqnge portions 7" retain the portlons 5 and the middl~
upper portion 6 o~ e~ch ~re~eO Fram~ 4 iB piuotally r~talned, wher~a~ ~rame 3 i8 rigidly retsined at a predetermined transverse obtuse angle relatl~- to beam 2 by means of self-tapping screw 10 (shown in Fig. 4), whlch extends through flsnga portion 7~ and portions 5 and 6.

2. A saw-horse as claimed in claim 1, wherein said bight portion is straight.
3. A saw-horse as claimed in claim 1, wherein said bight portion is bent upwardly to define a W-shaped frame with said leg portions, The central part of said first and second W-shaped frames being straight and in axial alignment with said end portions of the respective frames, and additional brackets secured to the underside of the central part of said beam and retaining said central straight portions of said two frames.
4. A saw-horse as defined in claim 1, 2 or 3, wherein each bracket is formed of a flat central portion and two outwardly-upstanding curved flange portions, each bracket secured to the under-side of said beam by volt means extending through said flat central portion, each said curved flange portion encircling and retaining said two frames and further including means extending through one of said curved flange portions and said second frame to rigidly secured said second frame to said brackets.
