Abstract
Abstract Disclosed herein is an improved combination of a hollow member and a backing member to be inserted therein. Another member such as a hinge is secured to the hollow member by machine screws which extend through the hinge and the wall of the hollow member and are tightened in threaded holes in the backing member. The hollow member is provided with an inwardly extending pawl and the backing member is adapted to be placed in a desired position in the hollow member by engagement with the pawl. When a plurality of backing members are to be placed in the hollow member, a plurality of pawls are formed in the hollow member so that they are laterally offset from each other with respect to the longitudinal direction of the hollow member and a void portion is formed in each backing member so that the pawls above the intended pawl do not interfere with the backing member as it is inserted in the hollow member.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
129 words
A combination of a hollow member and a backing member to be inserted in the hollow member characterized in that the hollow member is provided with an inwardly extending pawl and the backing member is adapted to be placed in a desired position in the hollow member by engagement with the pawl, said hollow member has a mounting plate provided with holes for passing screws at the place where another member is to be secured and said backing member comprises a backing plate portion having threaded holes and a leg portion extending from the backing plate portion substantially normally thereto and functioning to keep said backing plate portion in the hollow member adjacent and parallel to said mounting plate, said pawl being adapted to engage with said leg portion.
Claim 2
Dependent Claim
129 words
A combination of a hollow member and a backing member to be inserted in the hollow member characterized in that the hollow member is provided with an inwardly extending pawl and the backing member is adapted to be placed in a desired position in the hollow member by engagement with the pawl, said hollow member has a mounting plate provided with holes for passing screws at the place where another member is to be secured and said backing member comprises a backing plate portion having threaded holes and a leg portion extending from the backing plate portion substantially normally thereto and functioning to keep said backing plate portion in the hollow member adjacent and parallel to said mounting plate, said pawl being adapted to engage with said leg portion.
Claim 3
Dependent Claim
141 words
A combination of a hollow member and a plurality of backing members to be inserted in the hollow member characterized in that the hollow member is provided with a plurality of inwardly extending pawls laterally offset from each other with respect to the longitudinal direction of the hollow member and the backing members are adapted to be placed in their respective desired positions in the hollow member by engagement with the pawls, said combination being further characterized in that each of the backing members, at least those except for the one to be placed closest to the end of the hollow member through which the backing members are inserted in the hollow member, has a void portion so that it does not interfere with the pawls above the intended pawl as it is inserted in the hollow member through said end.
