ABSTRACT:
CROSS-REFERENCE TO RELATED APPLICATIONS
Not Applicable.
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 “U” 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.
