Abstract
A hinged bracket assembly comprising two elongated brackets one of which is placed inside the other with the same orientation and the two brackets being pivotally attached together on one end of the assembly. A table having a plurality of benches attached thereto comprises a plurality of the hinged bracket assemblies attached to the frame of the table and each of the benches is attached to one of the bracket assemblies to enable each bench to be rotated close to the table or away from the table in order to provide wheelchair access.

BACKGROUND




1. Field of Invention




This invention relates to hinges that are used in applications where supporting weight is not the primary concern and in particular to hinged brackets attached to a table with benches for swinging the benches away from the table.




2. Description of Prior Art




Hinges generally provide support for the weight of objects during the entire movement range of the object with relation to where the hinge is affixed. When the design restrictions inherent in providing the ability to support weight are removed, and a means of securing the movable object in a preferred position is attained, a new flexibility can be provided to an overall system especially where other objects of the greater, overall system may be degraded.




SUMMARY OF THE INVENTION




The present invention becomes a modified, slot and groove replacement that is hinged. In this way, the invention allows the members to swing apart from one another around a fulcrum provided by the invention. The invention forms an outer U-shaped bracket which can be put within the groove thereby becoming a groove of substantially the same width less twice the width of the material used to make the bracket. The outer bracket, is formed as an extended ā€œUā€ shape where the opening size has a characteristic outer bracket opening width. Also, an inner bracket is substantially the same as the outer bracket but with its opening width the same as the opening width of the outer bracket less twice the width of the building material of the inner bracket. The inner bracket is inserted within the outer bracket in the same orientation as the outer bracket and fastened at one end by a simple hinge typically formed with a sex bolt and corresponding holes in the two brackets. Both the inner and the outer brackets become integral halves of the newly formed hinge.

DESCRIPTION OF THE PREFERRED EMBODIMENT




Referring to

FIG. 1

, a perspective view of a preferred embodiment of the present invention of a hinged bracket assembly


10


to guide and restrict movements of objects is illustrated. The hinged bracket assembly


10


comprises an outer elongated bracket element


12


and an inner elongated bracket element


14


joined together at one end by a cylindrical rod


16


inserted in a first end portion of the bracket assembly


10


and having a sex bolt (not shown) inserted through an opposite first end portion of the assembly


10


whereby the sex bolt inserts into an open end of the cylindrical rod


16


.




Referring now to

FIG. 2

and

FIG. 2



b


,

FIG. 2



a


shows a side view of the outer elongated bracket element


12


, and

FIG. 2



b


shows an isometric view of the outer elongated bracket element


12


.

FIG. 2



b


shows a first member


22


that extends beyond a second member


24


of the outer bracket element


12


. Member


22


and member


24


are parallel to each other extending perpendicularly from opposite sides of center portion


13


. The right side of member


22


has a radius


26


which provides for the clearing the structure to which the hinged bracket assembly


10


is attached.

b


,

FIG. 3



a


shows a side view of the inner bracket element


14


, and

FIG. 3



b


shows a front elevational view of the inner bracket element


14


. The inner bracket element


14


comprises two members


28


and


30


which are parallel to each other extending at a 90 degree angle from opposite sides of the center portion


15


. The far right side of the hinged bracket assembly


10


comprises a cylindrical rod


16


and sex bolt (not shown) which inserts into the end of the cylindrical rod


16


. The right ends of members


28


,


30


as shown in

FIG. 1

are rounded. with the center portion


15


of the inner bracket element


14


being terminated at the cylindrical rod


16


. The inner bracket element


14


and the outer bracket element


12


rotate around the combination of the cylindrical rod


16


and the sex bolt.




In the operation of the invention the hinged bracket elements


12


,


14


swing apart from one another around a fulcrum such as cylindrical rod


16


. The outer bracket element


12


is formed as an extended ā€œUā€ shape where the opening size has a characteristic outer bracket element


12


opening width. The inner bracket element


14


is substantially the same as the outer bracket element


12


, but with its opening width the same as the opening width of the outer bracket element


12


less twice the width of the building material of the inner bracket element


14


. The inner bracket element


14


is inserted within the outer bracket element


12


in the same orientation as the outer bracket element


12


and fastened at one end by the hinge formed by the cylindrical rod


16


with the sex bolt inserted therein. Holes in the two bracket elements


12


,


14


are provided for receiving the cylindrical rod


16


and sex bolt. Both the inner and the outer bracket elements


12


,


14


become integral halves of the newly formed hinged bracket assembly


10


.
