Abstract
A sawhorse is constructed with brackets allowing the legs of the sawhorse to fold into a compact unit by having the legs interleave when folded. The legs pivot about a plane that is canted to allow each leg to rotate without interfering with any other leg. The length of the legs are not restricted in any fashion. The legs may also be locked in both the extended, or service position as well as the closed position. The bracket may be constructed of as few as two unique parts, and a pair may be nested together for compact shipping, storage, and display on a store shelf.
Description




BACKGROUND OF THE INVENTION




a. Field of the Invention




The present invention pertains generally to sawhorses, trestles, and other stands for use as temporary worksurfaces and specifically to brackets for the construction of sawhorses wherein the legs are allowed to fold.




b. Description of the Background




Carpenters, painters, and other individuals who need basic supporting surface that is raised from the floor have used sawhorses as an everyday tool. Scaffolding may be placed on the sawhorses to support workmen as they work, or workpieces may be placed directly on the sawhorses.




Many attempts have been made to create a useful sawhorse, but few inventions have met with much commercial success. Usually, the mechanisms contain many parts, including cross braces and the like, which add to the cost and make the devices less successful in the commercial arena.




Several sawhorses incorporate multiple motions for the legs to rotate, ref U.S. Pat. Nos. 2,431,898, 3,233,701, 3,282,379, 3,631,941, 3,978,943, 4,046,221, 5,439,073, 5,779,003, and 5,813,495. Each of these, in their own way, requires the user to move the legs in two prescribed motions to fold or unfold the legs. The dual motion of the legs adds complexity and cost to the sawhorse. The dual motion has the additional disadvantage of not being intuitive, thus limiting the appeal of the consumer who is likely to purchase the product.




As has been taught in U.S. Pat. No. 3,631,941, it is important for the user of the sawhorse to be able to set the height and size of the sawhorse for the job's purpose. It is advantageous for the user to select the leg length and thus overall height of the sawhorse without having restriction as to the length. All of the previously referenced patents, as well as U.S. Pat. Nos. 2,520,469, 2,573,740, 3,198,286, 3,618,704 and 3,951,233 do not allow for the legs to be appreciably longer than the main beam of the sawhorse.




Another useful feature for commercial viability is the compactness of the shipping configuration of the sawhorse bracket. Prior art, including U.S. Pat. Nos. 3,978,943 and 5,779,003, do not have this advantage.




The utility of the folding sawhorse depends on the usefulness of the sawhorse in both its folded and unfolded positions. In the folded position, the sawhorse legs should be locked firmly in place so that they do not open when being transported. The assembled sawhorse when folded should be transportable without having to keep the legs from falling open during transport. This allows the tradesman to hold the sawhorse in any position during transport or storage. U.S. Pat. Nos. 2,520,469, 2,573,470, 3,631,941, 3,978,943, 5,779,003, 5,813,495, and D328,355 all teach designs where the legs are locked in the open position but not the folded position.




In the open position, it is also critical for the legs to be firmly and securely braced, as the tradesman may lift the sawhorse by the main beam to reposition it several times during his course of using the sawhorse. A leg that flops around when the sawhorse is picked up is quite distracting and interferes with the tradesman's job. U.S. Pat. No. 3,978,943 teaches a method where the legs are secured in the open position by the friction of a toothed metal bracket engaging the wooden main beam of the sawhorse. This method would not be adequate for repeated uses, as the wooden beam would become marked by the repeated engagements and would no longer hold the leg securely when the main beam was lifted.




Commercial success is also dependent on the tradesman's ability to construct the sawhorse quickly and efficiently without having to make complicated compound angle cuts of lumber. U.S. Pat. No. 3,682,272 teaches a design for dually canted pivoting legs, but the construction relies on compound angled cuts.




A simple, intuitive locking mechanism is essential for commercial success of the invention. Tightening fasteners, as in U.S. Pat. No. 3,682,272 is not as desirable as a single press-to-release locking mechanism of the present invention.




For the carpentry trade, the sawhorse is preferred to have the main beam oriented with the smallest dimension of the beam is on the top and contacts the work which rests on the sawhorse. The carpenter also requires that the main beam of the sawhorse is made of wood and does not damage the blade of a saw. This orientation of the main beam also is the orientation that offers the most strength to the sawhorse. U.S. Pat. No. 2,431,898 teaches a device which has metal bracketry which could be damaged by a saw blade. U.S. Pat. Nos. 2,520,469, 2,573,740, 3,198,286, 3,233,701, 3,282,379, 3,631,941, 3,682,272, 3,700,072, 3,951,233, 4,046,221, 4,298,094, 4,967,877, 5,779,003, and 5,813,495 all teach designs which are less desirable in these regards due to the positioning of the main beam.




It would therefore be valuable to provide a bracket to assist the tradesman in building a sawhorse using conventional lumber that allows the legs to fold into a compact unit for transport. Further, the sawhorse bracket should be simple and contain as few a number of parts as possible. The brackets should create a sawhorse that has a simple, intuitive motion for extending and retracting the legs of the sawhorse. The brackets should allow the user to construct a sawhorse of virtually any height and width, with the minimum of restriction. The legs of the sawhorse should lock in place in both the open and closed positions so that the sawhorse is easily repositioned. Further, the bracket should be able to be packaged in a small form for efficient use of shipping and shelf space. The sawhorse should have the main beam oriented with a short side of the main beam at the top to minimize interference with the carpenter's saw or other tool.




SUMMARY OF THE INVENTION




The present invention overcomes the disadvantages and limitations of the prior art by providing a set of sawhorse brackets for building a sawhorse of common dimensional lumber. Further, the brackets create a sawhorse that the legs are foldable and interleave when folded. The legs of the sawhorse rotate in a plane that is doubly canted: first to allow the legs to splay when extended and a slight cant in the plane of the main beam such that the legs do not interfere with each other when folded.




The bracket incorporates two hinge points: a first hinge point where the legs rotate, and a second hinge point where the bracket grips the main beam of the sawhorse. The second hinge point allows the bracket to fold and nest with another bracket so that the pair may be packaged in a box. Further, when the brackets are out the package, the pair will stay together as a unit, for easy handling when the sawhorse is disassembled.




The pivot action of the legs is locked in both the open and closed position using the same mechanism. The locking mechanism is intuitive to a consumer and easy to operate.




The bracket is constructed of two unique parts, four of each are required to make a single sawhorse. The locking mechanism may be constructed of a third part or may be incorporated into one of the other main parts.




The present invention may therefore comprise a bracket for the attachment of a pair of folding legs to a sawhorse horizontal body comprising: a frame for receiving a longitudinal sawhorse body; two leg attachments for each receiving a sawhorse leg, the attachments being pivotally attached to the frame and each being adapted to swing from an extended, service position, to a folded position, the axis of rotation for the first leg attachment being such that the leg forms an acute angle diverging from the axis of the body in the horizontal plane when in the folded position and the second leg forms an acute angle converging to the axis of the body in the horizontal plane when in the folded position.




The present invention may therefore further comprise a bracket for the attachment of a pair of folding legs to a sawhorse horizontal body comprising: a frame comprising two surfaces diverging downward in the vertical plane and canted by an angle in the horizontal plane to a plane normal to the longitudinal axis of the sawhorse horizontal body, the frame adapted to attach to the sawhorse horizontal body, and a leg receiver mounted to each of the diverging surfaces, pivotally mounted and adapted to swing from an extended, service position to a folded position, each leg receiver adapted to receive a sawhorse leg.




The present invention may therefore further comprise a bracket for the attachment of a pair of folding legs to a sawhorse horizontal body comprising: a frame assembly comprised of two frames pivotally attached and adapted to clamp onto the sawhorse main body, each frame comprising a surface diverging downward in the vertical plane and canted by an angle in the horizontal plane to a plane normal to the longitudinal axis of the sawhorse horizontal body, and a leg receiver mounted to the diverging surface, pivotally mounted and adapted to swing from an extended, service position to a folded position, each leg receiver adapted to receive a sawhorse leg.




The present invention may therefore further comprise a foldable sawhorse comprising: a longitudinally extending sawhorse body; two brackets mounted onto the body; two legs pivotally mounted to each of the brackets and adapted to swing from extended, service positions, and positions folded underneath the body; the axis of the pivot mounts being adapted so that the legs clear and lie alongside and at an acute angle relative to one another when in the folded positions.




The advantages of the present invention are the simplicity of the bracket design, which comprises two or three unique parts, and the simplicity of the locking mechanism, both of which result in low per unit cost. The design is intuitive and easily understood by consumers. The bracket uses conventional lumber and does not require any special mitered cuts to produce a fully functional sawhorse. Further, the length of the sawhorse legs is unrestricted, and a sawhorse of any height can be constructed with the inventive brackets. A sawhorse produced with the brackets is sturdy and the legs rigidly lock in both the open and closed positions. The brackets nest into each other so that the packaging for a pair of brackets is simple and space-efficient.

DETAILED DESCRIPTION OF THE INVENTION





FIG. 1

illustrates a perspective view of an embodiment of the inventive brackets fashioned into a sawhorse


100


. A first bracket


102


and a second bracket


104


are connected to the sawhorse main beam


106


. Legs


108


and


110


attach to bracket


102


and legs


112


and


114


attach to bracket


104


. The sawhorse


100


is shown in the extended, or service position. From this illustration, the sawhorse resembles a conventional sawhorse in form and function.





FIG. 2

illustrates a perspective view of an embodiment of the inventive brackets made into a sawhorse


100


wherein sawhorse


100


is shown with the legs in the closed position. First bracket


102


and second bracket


104


are connected to the sawhorse main beam


106


. Legs


108


and


110


attach to bracket


102


. Leg


112


is attached to bracket


104


. Leg


114


is not visible in this view.




Leg


108


does not interfere with leg


112


when the legs are folded. Leg


112


folds in-between leg


108


and leg


110


and does not touch either leg. Further, leg


110


extends through an open area underneath bracket


104


. Each leg is slightly canted towards or away from the vertical plane of the horizontal main beam


106


, this canted angle allows the legs


108


,


110


,


112


, and


114


to interleave when folded without touching.




The legs lie near each other, but do not touch. Since the legs do not touch, when the legs of the sawhorse


100


are changed from the extended or service position to the closed position, any leg can be operated in any order.




There is no limitation on the length of the legs for the construction of a working sawhorse. Leg


110


extends through an open portion


202


of bracket


104


, which does not interfere with leg


110


; therefore, leg


110


may extend to any length whatsoever. Further, there is no limitation on the length of the main beam


106


in the present embodiment.




As also illustrated in

FIG. 2

, the folded sawhorse constructed with an embodiment of the present invention is very compact when folded. The legs fold such that they are in the same plane as the main beam


106


and as such present a very compact profile. Further, a gap


204


below main beam


106


makes for an easy handhold.





FIG. 3

is an illustration of a second perspective view of an embodiment of the inventive brackets made into a sawhorse


100


wherein sawhorse


100


is shown with the legs in the closed position. First bracket


102


and second bracket


104


are connected to the sawhorse main beam


106


. Legs


108


and


110


attach to bracket


102


. Legs


112


and


114


are attached to bracket


104


.





FIG. 4

is an illustration of an embodiment


400


of the present invention. First frame


402


is attached to second frame


404


. First leg bracket


406


and second leg bracket


408


are attached to frames


402


and


404


by rivets


410


and


412


, respectively. First frame


402


is assembled to second frame


404


by a rivet


414


. A second rivet along substantially the same axis as rivet


414


is hidden from view. Locking tab


416


is attached to the assembly by rivet


410


. Locking tab


418


is attached by rivet


412


.




Embodiment


400


is designed to be a cut length of conventional 2×4 or 2×6 standard size lumber for the horizontal main body. Further, embodiment


400


is designed accept legs constructed of cut lengths of conventional 2×4 lumber.




Frame


402


comprises teeth


420


that engage the main beam of the sawhorse on assembly. During assembly, the first frame


402


and second frame


404


are rotated about the axis of rivet


414


such that the teeth


420


are opened. When the main beam is presented, the frames


402


and


404


are then rotated about the axis of rivet


414


so that the teeth


420


engage the main beam. Screws or nails may be used in holes


422


to allow fasteners to be used to attach the frames


402


and


404


to the main beam.




Embodiment


400


is constructed from sheet metal, but other embodiments are contemplated being made from metal or plastic extrusion, machined metal or plastic parts, plastic molded parts, or other materials and processes while still keeping the two piece frame design similar to components


402


and


404


.




Other embodiments of the present invention may not have a frame portion comprised of two hinged components


402


and


404


and may be comprised of a single piece. The frame components may be a unitized sheet metal, extruded metal or plastic, molded plastic, or other unitized design. In a unitized design, the frame members may incorporate other methods of attaching to the main beam. These methods may include portions of the frame that are hammered into the main beam, snap features that grip the main beam, or other methods. Those skilled in the art may find different methods of construction and attachment while still maintaining within the scope of the present invention.




Locking tab


416


comprises a flexible area


424


, a locking protrusion


426


, and a push tab


428


. The protrusion


426


fits through a hole in frame


402


and into a second hole in the leg bracket


406


. The leg bracket


406


is held in place by the protrusion


426


engaging the hole in the leg bracket. For the protrusion


426


to be disengaged from the leg bracket


406


, the push tab


428


is pressed by the user until the protrusion


426


is disengaged.




Locking tab


416


may be made of metal or plastic, but it is designed to be flexible at least in the area


424


. Locking tab may further be constructed of more than one part. In the present embodiment of the invention, locking tab


416


is shown as constructed of one piece of sheet metal or sheet plastic. However, protrusion


426


and push tab


428


may either or both be second parts that are attached to the locking tab


416


. Further, the locking tab


416


may comprise a feature that is integral to the frame


402


and is formed out of the base material of frame


402


. The locking tab is generally designed so that the deformation of the flexible area


424


is completely elastic and does not undergo any permanent deformation during normal use.




Locking tab


416


may be formed with a curve in the area


424


which would bias the protrusion


426


outward and cause the locking tab


416


to be preloaded. Further, the protrusion


426


may be tapered such that protrusion


426


wedges into the frame


402


and leg attachment


406


. Such a wedge would, when accompanied with a biasing curve in the area


424


, would serve to tighten itself while the sawhorse is being handled.




Locking tab


416


may be attached to frame


402


by many different methods. A rivet through hole


410


may be inserted and formed. The leg attachment


406


may have some material formed up in the area of hole


410


which will be cinched down over the frame


402


and locking tab


416


to affect a joint. Other methods may include spot welding, other types of fasteners, etc.




The locking tab


416


may be attached to the outside of leg attachment


406


. In such a situation, pulling the tab away from frame


402


rather than pressing the tab inwards may operate the locking tab


416


. Such a tab may be formed as an integral feature of leg attachment


406


. Those skilled in the art may be able to create other locking mechanisms for the present invention without deviating from the scope and intent of the present invention.




The invention contains a locking mechanism for each leg assembly that permits locking a leg in an open and closed position, unlocking a leg for rotation to the other position and then locking that leg into that position. The locking mechanism locks the legs in both positions of the legs. This feature ensures that the sawhorse will be sturdy when open and easy to handle when closed. The locking mechanism is intuitive and easily described for commercial sale.




The locking tab


416


may also include a formed rib or other stiffening feature to stiffen the said area between the protrusion and the button


428


. Further, the button


428


may include a tab, lip, or other feature that protrudes from the outermost surface of button


428


and over the outermost surface of frame


402


at such a distance as to limit the distance that a user can depress the locking mechanism. This said tab would serve as a protection from deforming the locking tab


416


from permanent deformation by over bending the tab


416


past its elastic limit.




The aperture through frame


402


through which the protrusion


426


extends is designed to be the same size as the aperture of leg attachment


404


and the protrusion


426


to be slightly smaller than either of the apertures through the frame


402


or leg attachment


404


. The size difference between the apertures and protrusion


426


is selected so that any manufacturing variances, such as sheet metal burrs or differences in tooling, would prevent the protrusion from fully engaging through both apertures.




Leg bracket


408


comprises two walls


430


and


432


, each of which has attached tabs


434


and


436


, respectively. The walls


430


and


432


and tabs


434


and


436


are sized so that a conventional piece of lumber can fit within the leg bracket


408


. Tab


438


serves to limit the distance that a sawhorse leg may be placed inside the leg bracket


408


. Screws or other fasteners may be used in holes such as


440


to fasten the leg inside the leg bracket


408


. Other embodiments of the present invention may incorporate other fastening mechanisms, such as a set of teeth adapted to be hammered into the leg, or other locking mechanisms to attach a leg to bracket


408


. Those skilled in the art may be able to expand the methods of holding a leg into leg bracket


408


without deviating from the scope and intent of the present invention.




The leg bracket


408


has three cut outs


442


,


444


, and


446


. Second locking tab


418


has a protrusion


448


and push tab


450


. The locking mechanism locks the position of the leg bracket


408


in one of three positions. In the position that is illustrated, the locking tab protrusion


448


extends through the cut out


442


. When the push tab


450


is depressed, the locking tab protrusion


448


will disengage cut out


442


and allow the leg bracket


408


to rotate. The user may then rotate the leg bracket


408


in a clockwise direction. The user may optionally release the push tab


450


and continue to rotate the leg bracket


408


. The locking tab


418


would then apply some spring force against the locking tab protrusion


448


and the leg bracket


408


. As the leg bracket


408


attains a position where the leg of the sawhorse would be fully extended, the cut out


444


would allow the locking tab protrusion


448


to extend through cut out


444


by the spring force and secure the leg bracket


408


in place. The leg bracket


408


may also be unlocked and rotated another ninety degrees counter clockwise so that the leg bracket


408


is positioned 180 degrees from the positioned illustrated. This feature is only due to the symmetrical design of the sheet metal components used to create this particular embodiment and is not a necessary feature of all embodiments of the present invention.




The embodiment


400


is constructed of three unique formed sheet metal parts. While the invention does not preclude the use of other materials or designs, the simplicity of the preferred embodiment has the distinct commercial appeal of minimizing the tooling costs associated with the manufacturing the invention.





FIG. 5

illustrates a close-up view of a embodiment


400


of the invention attached to a sawhorse main beam


502


, a first leg


504


, and a second leg


506


. The plane of rotation for leg bracket


408


can be defined by two angles. Angle


508


defines an angle between face


510


of the main beam


502


and edge


512


of the leg


504


in the vertical plane. Angle


508


defines the splay of the legs, or the angle of the opening of the legs in the vertical plane. Typically, this angle may be 5 to 15 degrees, although the angle may be smaller or larger depending on the application.




Angle


514


defines the angle between the face


510


of main beam


502


and the edge


516


of the frame in the horizontal plane. Angle


514


is the twist or offsetting angle that allows the legs to interleave when folded. Angle


514


may be between 1 and 5 degrees, although other angles may be used depending on the application and design intent of the bracket designer. The spacing between the two brackets that comprise a sawhorse is affected by the angle


514


. For embodiment


100


in

FIGS. 2 and 3

, the minimum and maximum spacing between brackets


102


and


104


is determined by angle


514


. A larger angle


514


means that the spacing between brackets


102


and


104


would be shorter and if angle


514


were smaller.




Angle


514


allows one leg to fold convergent to the axis of the main beam


502


and the opposite leg to fold divergent to the main beam


502


. This is the manner by which the four legs of the sawhorse are able to interleave without interfering with each other.




The relationship of the angles


508


and


514


are the method by which the legs of the sawhorse constructed with the inventive brackets are able to open and close in one motion. When the legs are open, the legs are splayed so that the sawhorse is rigid and stable. When the legs rotate in the plane defined by the angles


508


and


514


, the leg moves in a plane that does not interfere with any other leg or member.




A typical assembly sequence to construct a sawhorse using the inventive bracket would be to cut legs


504


and


506


to length and assemble legs


504


and


506


into bracket


400


. The legs


504


and


506


would then be fastened into leg assemblies


408


and


406


respectively by fasteners. The leg brackets


406


and


408


would be positioned as illustrated in FIG.


5


. Main beam


502


would be positioned between the frame members


402


and


404


. The legs


506


and


508


would then be spread so that the frame members


402


and


404


grip the main beam


502


. Fasteners would then secure the frames


402


and


404


to main beam


502


. The process would be repeated for the second bracket and set of legs. Other sequences could be used to assemble a sawhorse using the inventive brackets without deviating from the scope of the invention.




The present embodiment of the invention uses conventional dimensional lumber that requires no special angled cuts to assemble. It is foreseeable that the ends of the legs may be cut at an angle so that the ends of the legs rest flat on the floor. This, however, is not a requirement for the performance of the invention.




The invention provides an arrangement whereby of the two legs at each end, one pivots along a plane that is convergent to the axis of the main beam and the other leg pivots along a plane that is divergent to the said beam, permitting the interleaving of the legs in the closed position in such a manner as to not interfere with the other legs of the assembly. In the specific example given, the plane of rotation, plane


518


, is divergent from the main axis of main beam


502


by angle


514


such that leg


504


, diverges from the main beam


502


. Leg


506


rotates along a plane which is canted the same amount in a convergent manner, allowing the leg


506


to fold in-between the opposite legs attached to a bracket identical to embodiment


400


. In the folded position, all of the legs can be locked in the folded position without touching or interfering with any other legs.





FIG. 6

illustrates an embodiment whereby two brackets


602


and


604


can be pivotally opened and nested into each other for shipping or storage. The leg attachments


606


and


608


are first positioned in the folded position for each bracket. Frames


610


and


612


, of each bracket assembly


602


and


604


, are rotated about axis


614


with respect to one another so that the outer faces of frames


610


and


612


are essentially parallel. Bracket assembly


604


is rotated so that the leg attachments


606


and


608


are towards the top. The two bracket assemblies


602


and


604


are then mated together so that the faces of frames


610


and


612


come in contact with the same faces of the opposite bracket, and the frames of one bracket assembly fit between the leg attachments of the opposite bracket assembly. In the nested position, the inside face of the leg attachment


608


would be in direct contact with the outer face of the frame


612


. The riveted joints


614


in the embodiment are selected such that the frames


610


and


612


may be rotated about the joint


614


by hand, but with enough friction so that the frames


610


and


612


stay in their positions without moving. It may be preferred to mate the two bracket assemblies with the outer faces of frames


610


and


612


angled slightly so that the leg attachments


606


and


608


are further apart than when the outer faces of frames


610


and


612


are parallel, then rotate the frames


610


and


612


about axis


614


after the said inner faces of the frames


610


and


612


of the opposite brackets are in contact with each other. The two brackets may be held with the friction in the riveted joints


614


or there may be mechanical engagement, such as a small tab in the leg attachment


608


that engages a hole in frame


612


in the opposite assembly.




The assembly illustrated in

FIG. 6

is a very compact form. A simple printed cardboard sleeve may be used to contain the products during shipping and for the advertisement and display of the product on the store shelves. Further, a sawhorse may be disassembled at a jobsite and the tradesman may reassemble the brackets into their nested form for storage and transportation to the next jobsite.




The foregoing description of the invention has been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the invention to the precise form disclosed, and other modifications and variations may be possible in light of the above teachings. The embodiment was chosen and described in order to best explain the principles of the invention and its practical application to thereby enable others skilled in the art to best utilize the invention in various embodiments and various modifications as are suited to the particular use contemplated. It is intended that the appended claims be construed to include other alternative embodiments of the invention except insofar as limited by the prior art.



Claims
  • 1. A bracket assembly for the attachment of two pair of folding legs to a sawhorse horizontal body comprising:two brackets, each of said brackets comprising a frame for receiving a respective end of said sawhorse body, two leg attachments for each receiving a respective pair of sawhorse legs, said attachments being pivotally attached to said frame and each being adapted to swing from an extended, service position, to a folded position in a horizontal plane substantially parallel to a longitudinal axis of said body, a single axis of rotation for one of said leg attachments being such that a first of said pair of legs forms an acute angle angled inward towards said axis of said body in said horizontal plane when in said folded position and a second of said pair of legs forms an acute angle angled outward from said axis of said body in said horizontal plane when in said folded position, so as to permit the respective pairs of legs to interleave when in the folded position when said brackets are adapted to be attached to the respective ends of said sawhorse body.
  • 2. The bracket assembly of claim 1 wherein a locking mechanism for each of said leg attachments is adapted to secure said leg attachments in said extended position.
  • 3. The bracket assembly of claim 2 wherein said locking mechanism is adapted to secure said leg attachments in said folded position.
  • 4. The bracket assembly of claim 1 wherein said sawhorse longitudinal body is comprised of common sized lumber.
  • 5. The bracket assembly of claim 1 wherein at least one of said sawhorse legs is comprised of common sized lumber.
  • 6. A sawhorse assembly comprising:a sawhorse body comprised of a horizontal beam, two pairs of legs, and two brackets, each of said brackets comprising a frame for receiving said sawhorse body, two leg attachments for each receiving a respective end of one of said pairs of said legs, said attachments being pivotally attached to said frame and each being adapted to swing from an extended, service position, to a folded position in a horizontal plane substantially parallel to a longitudinal axis of said body, a single axis of rotation for one of said leg attachments being such that a first of said pair of said legs forms an acute angle angled inward towards said axis of said body in said horizontal plane when in said folded position and a second of said pair of legs forms an acute angle angled outward from said axis of said body in said horizontal plane when in said folded position, so as to permit the respective pairs of legs to interleave when in the folded position and when said brackets are attached to the respective ends of said sawhorse body.
