5 Claims.

The present invention relates to improvements in saw horses and more particularly to saw horses having longitudinally extending rails and foldable legs secured thereto. The invention also relates to saw horses having means for longitudinally extending the same as well as means for providing a vertical extension to the supporting legs.

An object of the present invention is to provide a folding saw horse having a longitudinally eX- tending supporting rail and legs secured to each end thereof with means for hingedly securing the legs to the supporting rail for pivoting move ment towards each other and for positioning in juxtaposition to the supporting rail whereby the saw horse may be conveniently stored or transported.

A further object of the present invention is to provide a folding saw horse with means for releasably latching the hingedly secured legs in their supporting position relative to the supporting rail.

A still further object of the present invention is to provide a brace means for preventing movement of the legs with respect to the supporting rail when the latch means is in released position.

Another object of the present invention is to provide a saw horse having a pair of supporting rails, each of the supporting rails being provided with a pair of legs xedly secured thereto, said supporting rails being adapted to be secured together to provide an elongated saw horse.

A further object of the present invention is to provide means for rigidifying the elongated saw horse by providing connecting struts between intermediate portions of the supporting rails and the lower end portions of the legs.

It is also an object of the present invention to provide a conventional saw horse with means for vertically extending the same with respect to follow. The best forms in which I have conf templated employing my invention are clearly illustrated in the accompanying drawings, wherein:

Figure 1 is a side elevational view of a first form of folding saw horse;

Figure 2 is a top plan view of a portion of the saw horse of Figure l;

Figure 6a is an enlarged view in perspective of the brace means;

Figure 7 is a side elevational view of a modified form of longitudinally extensible saw horse;

Figure 8 is a top plan View of the saw horse of Figure 7;

Figure 9 is a vertical transverse sectional view taken substantially along the plane of line 9 9 of Figure 7;

Figure 10 is an end elevational view of a third form of vertically extensible folding saw horse; and

Figure 11 is a detail perspective view of the connecting bracket employed in the third form of the invention for receiving the lower ends of the legs of the conventional saw horse.

Referring more particularly to the drawings, wherein like numerals designate like parts throughout, numeral l! designates generally a first form of folding saw horse, the numeral l2 designates generally the elongated saw horse construction while the numeral I4 designates generally the vertical extension means for a conventional saw horse.

The folding saw horse construction I0 shown in Figures 1 through 6 is comprised of a first hinge bracket I6, latch elements I8 and 2U, and brace means 22.

The hinge bracket It is comprised of a first portion 24 which is iixedly secured to the supporting rail 26 by means of the bolts 28. The first portion 2d is of U-shaped cross-section with the upstanding walls 30 in abutment with the side lwalls of the supporting rail 26. The iirstportion 24 has a second portion 32 secured thereto, the second portion 32 being formed from angulated sheet metal section 34 providing sockets for receiving the upper ends 36 of the legs 38. The second portions 32 are also formed with latch elements A0 which are comprised of portions of the plate 34 being slit and bent to provide an offset latching means.

A third portion 42 ofv the rst bracket IS is from eachl other.

hingedly connected to the first portion |6 by means of the hinge 44 and has a pair of

hinge sections

46 and 48 hingedly secured thereto by the longitudinally extending

hinges

50 and 52. The

hinge sections

46 and 48 are comprised of angulated sheet metal strips which encircle three sides of the legs and are secured to the inner and guter surfaces of the legs by means of the bolts The longitudinally extending supporting rail 26 has a pair of latch elements 56 and 5S pivotally secured thereto by means of the bolt 60 and wing nut 62. The

latch elements

56 and 58 are formed with

offset portions

64 and 66 which are disposed in parallel relation to the side walls of the rail 26 and are adapted to be engageable over the offset portions 34. The

latches

56 and 58 are formed with detent slots 65 for engagement with the detents 40 whereby when the upper ends 36 of the legs 38 are engaged underneath -the offset portions -34, 64 and 66, the

latching elements

56 and 58 will xedly maintain the entire saw horse in-its supporting relation.

Reciprocably received on the underside of the hinged portion 42 is the brace means 22 having the form of a plate longitudinally and slidably fitted between and supported by the hinges 50,

52 and which has a pair of angulated depending rear end portions 68, and a depending front lip 69 Vnotched as at 69 to play between said

hinges

50, 52. The brace means 22 is slidable forwardly to interpose the angulated portions 68 between the

hinge sections

46, 48, as best shown in Figure 5, to maintain the legs 38 swung away The lip 69 engages the hinge 44 to limit forward sliding of said brace means. The brace means 22 may be slid rearwardly to withdraw said portions 68 from between the

sections

46, 48, as shown in dotted lines in Figure 5, so that said

sections

46, 48 may .be swung toward each other and the legs 38 correspondingly swung. A depending stop element 12 on the hinge plate 42 extending into a slot 16 in said brace means 22 limits rearward sliding of said brace means.

An elongated rotatable element 14 is secured A to the underside of the rail 26 by means of the screw 16 whereby when the element 14 is longitudinally disposed relative to the rail 26, the

end 18 will be engageable with the brace means m 22 for preventing outward movement thereof. The element 14 may be rotated to a transversely extending position to permit the retraction of the brace means 22 when it is desired to fold the saw horse.

From the foregoing, the manner in .which the saw horse is folded will'be readily understood by one skilled in the art. First, the element 14 is rotated to a transversely extending position and the brace means 22 is slid into its rearward limit of movement. The

latch elements

56 and 58 are pivoted upwardly upon loosening of the wing nut 62, whereupon the legs 38 may be hingedly moved towards each other about the

hinges

50 and 52 and also hingedly moved to a longitudinally extending position about the hinge 44. A conventional hook 80 and eyelet 82 are secured to the rail 26 and leg 38 respectively for latchably retaining the legs in folded position.

As seen in Figure 2, the latch elements I8 and are formed with laterally extending

finger engaging portions

84 and 86 and rigidifying

plates

88 and 90. The latching elements may be pivoted about their pivotal axis `by engaging the

finger engaging portions

84 and 86. The angulated por- 4

tions

64 and 66 of the latch elements |8 and 20 are substantially rigidied by the

plates

88 and 90.

Looking now at Figures '1 and 8, the elongated saw horse construction will be seen to comprise a pair of

rails

92 and 94 having pairs of legs 96 angularly extending therefrom at their outer ends. Each of the

rails

92 and 94 has a bracket 98 or |00 secured thereto. The brackets 98 and |00 are of rectangular cross-section and are secured to their

respective rails

62 and 94 by means of the bolts |02. The internal cross-sectional area of the brackets 98 and |00 is sufficient to receive the two longitudinally extending

rails

92 and 94.

Each of the

rails

92 and 94 has a plate |04 or `|06 secured thereto by means of the bolts |08.

The plates |04 and |06 have arcuated portions I I8 formed with transversely extending slots H2.

Each of the

rails

92 or 94 has a pair of rigidifying'rods H4 and ||5 for interconnecting the rails to the legs 96. The rods H4 have connecting brackets H6 formed on their upper ends, the brackets H6 having arcuated end portions H8 positionable through the slots H2 for engagement over the arcuated ends H8 of the plates |64. The opposite ends of the rods H4 have elongated brackets |28 secured thereto and formed with longitudinally extending slots |22. The legs 96 are formed with rotatable latch elements |24 receivable through the slots |22 for releasably securing the rigidifying rods H4 and H5 to the lower ends of the legs 96.

Looking now at Figures 10 and 11, the vertically extensible folding saw horse construction will be described. A conventional saw horse H having a longitudinally extending supporting rail and angularly extending legs |50 has vertical extension means `I4 secured to the lower ends of the legs |50 for maintaining the saw horse in raised relation to the supporting surface S.

Joinder struts |66 have connecting brackets |68 and |18 secured to their outer ends and formed with elongated slots |12 and |14. The

l. extension legs E52 have rotatable elements S24' secured thereto for positioning through the slots H2 and l'ill for fixedly retaining the legs 152 and joinder struts 65 together.

Having described the invention, what claimed as new is:

1.
