Abstract

A self-contained adjustable support device designed to provide stable work supporting surfaces for a wide variety of objects in the legs extended position and also provides a legs collapsed position for storage and/or transport. The support device includes a pair of latch brackets with each latch bracket constructed to lock a pair of legs to a central beam either in the legs extended position or the legs collapsed position; and to allow each pair of legs to be adjusted to various positions along the beam.

Claims

1. A support device comprising:

(a) a support beam member having a bottom surface;

(b) leg structure; and

(c) bracket means pivotally attaching said support beam member to said leg structure for allowing said leg structure to pivot between an extended position and a collapsed position, said bracket means including pivot rod means extending through said beam member for allowing said beam member to pivot thereabout, said bracket means including support means rigidly mounted relative to said pivot rod means for supportingly engaging said bottom surface of said beam member, said bracket means including attachment means rigidly mounted relative to said pivot rod means and said support means for removably attaching said pivot rod means and said support means to said leg structure, said support means including means for supportingly engaging said beam member when said leg structure is in said extended position to positively lock said leg structure in said extended position and for supportingly engaging said beam member when said leg structure is in said collapsed position to positively lock said leg structure in said collapsed position, said attachment means being adjustable between a loose and a tight position while attached to said leg structure, the movement of said attachment means toward said tight position causing said support means and said pivot means to coact to wedge said support beam therebetween.

2. A support device comprising:

(a) a support beam member;

(b) leg structure; and

(c) bracket means pivotally attaching said support beam member to said leg structure, said bracket emans including pivot rod means extending through said beam member for allowing siad beam member to pivot thereabout, said bracket means including support means rigidly mounted relative to said pivot rod means for supportingly engaging said beam member, said bracket means including attachment means rigidly mounted relative to said pivot rod means and said support means for removably attaching said pivot rod means and said support means to said leg structure;

said support beam member having a bottom surface and a top surface, said bracket means allowing said leg structure to pivot relative to said beam member between a first position with said leg structure located generally parallel with said beam member and a second position with said leg structure located generally perpendicular to said beam member;

said support means of said bracket means including a first flange for supportingly engaging said top surface of said beam member when said leg structure is in said first position and includes a second flange for supportingly engaging said bottom surface of said beam member when said leg structure is in said second position.

3. The support device of claim 2 in which said first flange is located generally perpendicular to said second flange.

4. A support device comprising:

(a) an elongated longitudinal support beam member having a first end and a second end;

(b) first leg structure;

(c) a first bracket means attaching said first leg structure adjacent said first end of said support beam member for allowing said first leg structure to pivot between a first position in which the plane of said first leg structure is generally parallel with the plane of said support beam member and a second position in which the plane of said first leg structure is generally perpendicular to the plane of said support beam member, said first bracket means including pivot rod means for allowing said beam member to pivot thereabout, including support means rigidly mounted relative to said pivot rod means for supportingly engaging said beam member, and including attachment means rigidly mounted relative to said pivot rod means and said support means for removably attaching said pivot rod means and said support means to said first leg structure;

(d) a second leg structure;

(e) second bracket means attaching said second leg structure adjacent said second end of said support beam member for allowing said second leg structure to pivot between a first position in which the plane of said second leg structure is generally parallel with the plane of said support beam member and a second position in which the plane of said second leg structure is generally perpendicular to the plane of said support beam member, said second bracket means including pivot rod means for allowing said beam member to pivot thereabout, including support means rigidly mounted relative to said pivot rod means for supportingly engaging said beam member, and including attachment means rigidly mounted relative to said pivot rod means and said support means for removably attaching said pivot rod means and said support means to said second leg structure;

said support beam member having a bottom surfce and a top surface;

said support means of each of said bracket means supportingly engaging said bottom surface of said support beam member when said first and second leg structures are in said second position;

said support means of each of said bracket means supportingly engaging said top surface of said support beam member when said first and second leg structures are in said first position;

said attachment means of each of said bracket means being adjustable between a loose position and a tight position while attached to said leg structure, the movement of said attachment means toward said tight positions causing said support means and said pivot emans to coact to wedge said support beam member therebetween;

said first leg structure having a threaded aperture therein,

(f) a first bolt member screwably mounted in said threaded aperture of said first leg structure;

said first bracket means having a slot defining at least in part said attachment means and through which said first bolt member extends, screwing said first bolt member into said threaded aperture of said first leg structure being effective to move said attachment means to said tight position;

said second leg structure having a threaded aperture therein; and

(g) a second bolt member screwably mounted in said threaded aperture of said second leg structure;

said second bracket means having a slot defining at least in part said attachment means thereof and through which said second bolt member extends, screwing said second bolt member into said threaded aperture of said second leg structure being effective to move said attachment means to said tight position.
