BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to the field of shelf brackets, more specifically, a shelf bracket that is adapted to secure itself against a fence or baluster.

SUMMARY OF INVENTION

The self-supporting fence or baluster shelf bracket is a device that is adapted to attach onto and support itself perpendicularly with respect to a fence picket or baluster. Moreover, the self-supporting fence or baluster shelf bracket is adapted to interface with the fence picket or baluster provided the fence picket or baluster is vertically oriented. The self-supporting fence or baluster shelf bracket includes a shelf-supporting arm and a back support member that are parallel with one another, and translate relative to one another via a pair of lever arms. A spring attaches between the pair of lever arms to provide a compressive force that draws the shelf-supporting arm and the back support member together. Installed, the fence picket or baluster is adapted to be sandwiched between the shelf-supporting arm and the back support member. The shelf-supporting arm is elongated and able to receive and support a shelf member thereon and at a perpendicular orientation with respect to the fence picket or baluster. The shelf member and applicable load provide a bending moment force that is countered via the collaboration of the fence picket or baluster, the back support member and the pair of lever arms. The lever arms provide a counter bending moment that helps to secure the self-supporting fence or baluster shelf bracket in place on the fence picket or baluster.

These together with additional objects, features and advantages of the self-supporting fence or baluster shelf bracket will be readily apparent to those of ordinary skill in the art upon reading the following detailed description of the presently preferred, but nonetheless illustrative, embodiments when taken in conjunction with the accompanying drawings.

Detailed reference will now be made to a plurality potential embodiments of the disclosure, which are illustrated in FIGS. 1 through 5.

The self-supporting fence or baluster shelf bracket 100 (hereinafter invention) comprises a shelf-supporting arm 101 and a back support member 102. The shelf-supporting arm 101 and the back support member 102 are adapted to sandwich a fence picket or baluster 200 there between. The shelf-supporting arm 101 extends perpendicularly away from the fence picket or baluster 200 in order to support at least one shelf board 103 thereon. In use, the invention 100 is able to support the at least one shelf board 103 at a perpendicular orientation with respect to the fence picket or baluster 200 and a fence 201.

As a side note, the invention 100 is adapted for use with the fence 201. The term fence 201 may be more broadly used to determine a handrail along a stairway or walkway. It shall be duly noted that the invention 100 may be utilized in other environments aside of a traditional picket fence. Handrails provided along a walkway or stairs may also be utilized, and shall fall within the purview of applicable uses of the invention 100.

The shelf-supporting arm 101 is further defined with a rear, shelf surface 104. The back support member 102 is further defined with a front, back surface 105. The rear, shelf surface 104 of the shelf-supporting arm 101 is adapted to interface with a first picket or baluster surface 202 of the fence picket or baluster 200; whereas the front, back surface 105 of the back support member 102 is adapted to interface with a second picket or baluster surface 203 of the fence picket or baluster 200. The first picket or baluster surface 202 is opposite the second picket or baluster surface 203.

The shelf-supporting arm 101 is further defined with a top shelf surface 106 atop of which the at least one shelf board 103 rests. Shelf board brackets 107 are provided on distal ends of the top shelf surface 106. The shelf board brackets 107 help to secure the at least one shelf board 103 atop of the shelf-supporting arm 101.

The shelf-supporting arm 101 is affixed and translates with respect to the back support member 102. Moreover, at least one lever arm 108. The at least one lever arm 108 is pivotably attached to the shelf-supporting arm 101 as well as the back support member 102. The at least one lever arm 108 is a “U” shaped bracket further defined with a first lever end 109 and a second lever end 110. The first lever end 109 is threaded and is secured to the back support member 102 via a first threaded nut 111. The second lever end 110 is threaded and is secured to the shelf-supporting arm 101 via a second threaded nut 112. The at least one lever arm 108 ensures that the shelf-supporting arm 101 and the back support member 102 are parallel with one another in order to adaptively sandwich the fence picket or baluster 200 there between.

The invention 100 as depicted in the figures, shows the at least one lever arm 108 as a pair, and being further defined as a first lever arm 112 and a second lever arm 113. The first lever arm 112 is parallel with and positioned above the second lever arm 113. A spring 114 is connected between the first lever arm 112 and the second lever arm 113 in order to bias the back support member 102 to the shelf-supporting arm 101. The spring 114 helps to prevent over-rotation of the first lever arm 112 and the second lever arm 113 with respect to the shelf-supporting arm 101 and the back support member 102.

Referring to FIG. 3, both the first lever arm 112 and the second lever arm 113 form an angle 115 with the at least one shelf board 103. The angle 115 increases when the invention 100 is not in use with the fence picket or baluster 200 via the spring 114.

In use, the invention 100 secures itself onto the fence picket or baluster 200 by utilizing a bending moment 155 about the fence picket or baluster 200. The bending moment 155 applies a tensile force 156 onto the first lever arm 112 in order to pull the back support member 102 towards the shelf-supporting arm 101. Moreover, the bending moment 155 generates a compressive force 157 onto the second lever arm 113 in order to push the shelf-supporting arm 101 towards the fence picket or baluster 200. The bending moment 155 is increased upon addition of an object 300 onto the at least one shelf board 103 (see FIG. 5).

It shall be noted that the first lever arm 112 and the second lever arm 113 are adapted to interface against an inner picket or baluster surface 210 of the fence picket or baluster 200. The inner picket or baluster surface 210 is adjacent the first picket or baluster surface 202 and the second picket or baluster surface 203. The back support member 102 is ideally a rectangular block; whereas the shelf-supporting arm 101 may have a curved edge and is generally elongated. Moreover, the shelf-supporting arm 101 is generally perpendicular with respect to the back support member 102.

Referring to FIG. 4, the invention 100 may utilize a pair of back support members 102 as well as a pair of the shelf-supporting arms 101. A distance 180 spans between the pair of back support members 102 as well as the pair of the shelf-supporting arms 101. The distance 180 enables the at least one shelf board 103 to span across the distance 180 in order to support the object 300 thereon.

With respect to the above description, it is to be realized that the optimum dimensional relationship for the various components of the invention described above and in FIGS. 1 through 5, include variations in size, materials, shape, form, function, and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the invention.

It shall be noted that those skilled in the art will readily recognize numerous adaptations and modifications which can be made to the various embodiments of the present invention which will result in an improved invention, yet all of which will fall within the spirit and scope of the present invention as defined in the following claims. Accordingly, the invention is to be limited only by the scope of the following claims and their equivalents.
