Infinitely adjustable support bracket

Claim 2

An infinitely adjustable support structure comprising: (a) an upright member fixed in position and having an interior way with spaced, opposed, front and rear surfaces and an elongate opening; (b) a bracket member having an elongate arm with a latch portion at one end, said latch portion being in said interior way and said arm extending forwardly therefrom through said opening; (c) said latch portion being in fixed relation to said arm and inclined relative thereto with opposed edges for holding engagement with said front and rear surfaces respectively in response to a load on said arm; (d) a resilient member connected to the arm and the latch portion and having a gripping portion extended therefrom, said gripping portion resiliently engaging said front and rear surfaces and exerting pressure on said latch portion to urge same into inclined relationship; and (e) said arm being released for vertical movement when said arm is raised, releasing said opposed edges of said latch portion from engagement with said front and rear surfaces, and whereby the resilient member urges downward rotation of the arm in response to raising the arm for re-engagement of said latch portion with said front and rear surfaces.

Claim 3

An infinitely adjustable support bracket structure comprising: (a) an upright, elongate, channeled member having an interior way defined by spaced, opposite, side walls, a rear wall having an interior surface and extending between said side walls and a pair of collinearly aligned front flanges having interior surfaces and connected to said side walls, said front flanges having respective free edges spaced from each other and defining an elongate slot open to the interior way of said channeled member; (b) means for maintaining said channeled member in upright position; (c) an arm member extended outwardly from said slot and infinitely variable in position therealong, said arm member extended from a plate having front and rear edges and top and bottom surfaces, said arm member being diagonally connected to said plate at said bottom surface, said plate being slidable in the interior way of said channeled member when said arm member is swung upwardly relative thereto and fixed in diagonally lodged position in the interior way of said channeled member when said arm member is substantially normal thereto with said front edge in engagement with said front flanges interior surfaces and said rear edge in engagement with said rear wall interior surface and with the weight of said arm member tending to rotate said plate edges into engagement position; (d) a resilient means connected to said arm member and said channeled member and urging said arm member to a position substantially normal to said channeled member; and (e) said resilient means includes a spring member having an arm portion engaging said arm member, said arm portion extending from a hook portion having a rear portion engaging the interior of said rear wall and a front portion engaging the interior surfaces of said front flange member, said arm portion being resilient relative to said hook portion and exerting downward rotational force on said arm member in response to upwardly swinging movement of said arm relative to said channeled member.

Claim 4

An infinitely adjustable support bracket structure comprising: (a) an upright, elongate, channeled member having an interior way defined by spaced, opposite, side walls, a rear wall having an interior surface and extending between said side walls and a pair of collinearly aligned front flanges having interior surfaces and connected to said side walls, said front flanges having respective free edges spaced from each other and defining an elongate slot open to the interior way of said channeled member; (b) means for maintaining said channeled member in upright position; (c) an arm member extended outwardly from said slot and infinitely variable in position therealong, said arm member extended from a plate having front and rear edges and top and bottom surfaces, said arm member being diagonally connected to said plate at said bottom surface, said plate being slidable in the interior way of said channeled member when said arm member is swung upwardly relative thereto and fixed in diagonally lodged position in the interior way of said channeled member when said arm member is substantially normal thereto with said front edge in engagement with said front flanges interior surfaces and said rear edge in engagement with said rear wall interior surface and with the weight of said arm member tending to rotate said plate edges into engagement position; (d) a resilient means connected to said arm member and said channeled member and urging said arm member to a position substantially normal to said channeled member; and (e) said resilient means includes a spring member having an arm portion engaging said arm member, said arm portion extending from a hook portion having a rear portion engaging the interior of said rear wall and a front portion engaging the interior surfaces of said front flange member, said arm portion being resilient relative to said hook portion and exerting downward rotational force on said arm member in response to upwardly swinging movement of said arm relative to said channeled member.
