A sawhorse having legs which are pivotally mounted so as to swing between the normal operative positions and positions underneath and adjacent the sawhorse body. The legs are pivoted to swing in planes which are laterally spaced so that they do not interfere in the folded position. These planes include two planes which are at small angles to planes longitudinal of the sawhorse body to achieve the necessary clearance with one another. Means are provided for releasably fastening the legs in either the extended or folded position.

' sum 2 or 2 INVENTOR lav/a2 5 6 I.BYW%@ 1 FOLDABLE SAWHORSE BACKGROUND OF THE INVENTION This invention relates generally to sawhorses, and
more particularly to a sawhorse having legs which are conveniently foldable into an out-of-the way position for storage or transportation.
Sawhorses occupy considerable space, and are inconvenient both to store and transport. Generally, when not in service, they stand around the yard, or workshop floor, occupying substantial space, and presenting a degree of nuisance by their presence. When it becomes necessary to store them away, or to transport them to or from a job-site, they are found to be awkward in shape, and to occupy considerable space. A general purpose of the invention is to meet these problems by the provision of a sturdy but foldable sawhorse, whose legs can be folded in a unique manner so as to provide a compact package for either storage or transportation.
' BRIEF DESCRIPTION OF THE INVENTION In accordance with the invention, the four legs of the sawhorse are pivotally connected to support blocks fixed to the underside of the sawhorse body in such a manner that they may be swung into folded-away posi- DESCRIPTION OF THE DRAWINGS An illustrative embodiment of the invention is shown in the drawings, in which:
FIG. 1 is a perspective view of a sawhorse in accordance with the invention;
FIG. 2 is a side elevational view of the sawhorse in FIG. 1, with the legs in folded position;
FIG. 3 is an end elevational view of the sawhorse in FIG. 2;
FIG. 4 is a bottom plan view of the sawhorse, with the legs in folded position;
FIG. 5 is an enlarged section taken on the line 5--5 of FIG. 1;
FIG. 6 is an enlarged fragmentary detail within the circular arrow 6 in FIG. 5;
FIG. 7 is a fragmentary detail taken in accordance with the section line 7-7 of FIG. 5;
FIG. 8 is a sectional view taken on the section'line 8-8 of FIG. 5;
FIG. 9 is a section taken in accordance with the section line 9-9 of FIG. 2; and
FIG. 10 is an elevational view showing the extended sawhorses stacked.
DESCRIPTION OF A PREFERRED EMBODIMENT The illustrative embodiment of the invention is shown to embody a body 10 and legs 11, the latter, when the sawhorse is in service, standing in unfolded or extended position as in FIG. 1, but being pivotally mounted to the body so as to be capable of folding into the position shown in FIGS. 2 to 4, particularly. The sawhorse, body and legs, is composed preferably of wood, but other materials are, of course, not excluded. The body embodies a plank 10a of rectangular section, and may be conveniently referred to as a body plank. Forming a component part of the body structure, and recessed into the underside of the body plank 10a, near opposite ends'thereof, are two keystone-shaped blocks 12. These blocks 12 may be approximately one and one-half inches in thickness, and are positioned transversely of the body plank 10a, just inside the pairs of legs 11. The small end of the keystone block 12 is uppermost, and seated and cemented in recess 13 in the underside of the body member 10a. The wide end of the block 12 may be of the same width as the body member 10a, and each block 12 has I opposite downwardly and outwardly inclined side edges 14 and 15, of the same outward slope as the legs 1 1, to which the legs are pivotally connected. The keystone block 12 is buttressedon both sides by triangular blocks 160, which may be cemented to the underside of the body member 10a and to the block 12.
The legs 11 are comprised of flat wooden boards, cut at their lower ends at an angle to engage flush against the floor when unfolded. They are positioned adjacent to and with the same inclination as the sloping said edges 14 and 15 of the blocks 12. These blocks 12 are in effect parts of the fixed body, and constitute the fixed leg support means of the body. As seen in FIG. 1, the two legs on each side are inclined apart, and the two legs at each end are also inclined apart, generally in the manner of conventional sawhorses.
Preferably, and in the present embodiment, the confronting surfaces of the legs 11 and the inclined edges 14 and 15 of the blocks l2-are provided with face plates 16a and 17, respectively, composed of a smoothsurfaced material of good wearing quality, and fastened in place by flat headed screws, as illustrated.
The legs are pivotally mounted to the block 12 by bolts 20 having conical, screw-threaded wood screw portions 20a for screwing into the block 12, and cylindrical screw-threaded shank portions 20b to receive washers 21 and wing nuts 22. The wood screw sections are screwed into the edges 14 and 15 of the block, perpendicularly thereto, through suitable apertures in the face plates 17, and the cylindrical threaded shank portions 20b pass loosely, with substantial clearance, through holes 24 in the legs 11. The washers and wing nuts go on as illustrated in FIG. 5.
The upper ends of the legs 11 are cut with angular upper end edge portions 30 adapted for flush supporting engagement with the horizontal underside of the body member 10a. The inside comers of the upper ends of the legs are cut away, at 32, for a reason that will presently be explained. The angle of the cut at 32, when the legs are in the erected position of FIG. 1, is preferably substantially 45 relative to the horizontal body member 10a.
In the position of FIG. 1, with upper end edges 30 of the legs in supporting engagement with the body member 10a, the screw members 20b are centered in the leg holes 24. The legs then do not press against the screw members. The wing nuts will be understood to be tightened at this time, clamping the legs in position against the body blocks 12. To fold the legs under, the
are clamped in extended, service position, with said pivot shanks clear of the perimeters of said leg apertures, and the upper ends of said legs being additionally so formed as to permit swinging of said legs on said pivot shanks when said legs are lowered relative to said apertures in order to swing said legs to folded position.
