Abstract
A drill bit is connected to a drill in a simple and rapid manner and used to drill a hole in a backing which may be of wood, plastic or other material in which threads can readily be formed. A threaded insert which has a slightly greater diameter than the hole is then connected to the drill bit in the same manner as the drill and driven by the drill into the hole. The insert forms matching threads in the walls of the hole so that the insert is threadably attached to the backing. A retainer from which a hook is suspended is formed in the insert to permit the hanging of fixtures on the insert.
Claims9
A device for removably supporting a fixture on a backing comprising:
- a drill bit for use in driving a hole in said backing;
- an insert member having an outer diameter slightly greater than the diameter of said hole, said insert member having a thread formed on the outer wall thereof;
- a drill chuck for alternatively attaching said drill bit or said insert to a drill;
- said drill being employed to drive said insert member into said hole, the thread formed on the insert forming a matching thread on the wall of said hole, the insert member threadably engaging the wall of the hole and thereby being removably attached thereto;
- and
- means for removably supporting said fixture on said insert.
A method for removably supporting a fixture on a backing member comprising the steps of:
- drilling a hole in a backing member with a drill connected to a drill bit;
- driving a cylindrical insert member having a threaded outer surface and having a diameter slightly greater than that of said hole into said hole with said drill connected to said drill bit to form a threaded surface on the surface of said hole such that the insert member threadably engages the surface of the hole, and
- removably supporting said fixture on the inner wall of said insert.
