Abstract
Abstract A support for a ceiling fan or other fixture has a pair of slidably interconnected, pointed lances adapted to be driven into engagement with spaced structural members. A tool-strikable striking element is adapted to be coupled to each lance at a selected location along the length thereof. The support is adapted to be installed through a small hole in a preexisting ceiling or wall.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
190 words
A method of installing a fixture support on a pair of spaced structural members through a small hole in a wall member which is supported on and conceals the structural members, and support having: a pair of elongated lances slidably interconnected for relative longitudinal sliding movement, each of the lances being shorter than the distance between the structural members; member engaging means at the distal end of each of said lances for engaging the structural members and supporting the lances thereon when the lances are driven longitudinally in opposite directions against the structural members; and striking means associated with said lances intermediate the ends thereof; the method comprising the steps of: inserting said interconnected lances through said hole into the space behind said wall member and between said structural members; orienting said lance transversely of said structural members; extending said lances until the member engaging means of each lance abuts its respective structural member; and inserting a striking tool through sale hole and striking the striking means associated with said lances with said tool in longitudinally opposite directions to force said member engaging means into engagement with said structural members.
Claim 2
Independent Claim
190 words
A method of installing a fixture support on a pair of spaced structural members through a small hole in a wall member which is supported on and conceals the structural members, and support having: a pair of elongated lances slidably interconnected for relative longitudinal sliding movement, each of the lances being shorter than the distance between the structural members; member engaging means at the distal end of each of said lances for engaging the structural members and supporting the lances thereon when the lances are driven longitudinally in opposite directions against the structural members; and striking means associated with said lances intermediate the ends thereof; the method comprising the steps of: inserting said interconnected lances through said hole into the space behind said wall member and between said structural members; orienting said lance transversely of said structural members; extending said lances until the member engaging means of each lance abuts its respective structural member; and inserting a striking tool through sale hole and striking the striking means associated with said lances with said tool in longitudinally opposite directions to force said member engaging means into engagement with said structural members.
Claim 3
Dependent Claim
70 words
A method according to claim 1 wherein said striking means comprises at least one tool-strikable striking element and a plurality of longitudinally spaced coupling elements on said lances adapted to engage said striking element, the method further comprising the step of positioning a striking element in engagement with a coupling element on each lance near the opposite edges of said hole to allow room for the backswing of said tool.
Claim 4
Dependent Claim
52 words
A method according to claim 2 wherein said striking element is removed from one lance after it is struck with said tool in one direction and coupled to a coupling element on the other lance near the opposite edge of said hole to be struck with said tool in the opposite direction.
Claim 5
Dependent Claim
33 words
A method according to claim 2 wherein said striking means comprises two tool-strikable striking elements, and said striking elements are engaged with coupling elements on separate lances near opposite edges of said hole.
Claim 6
Dependent Claim
37 words
A method according to claim 1 further comprising the step of spacing said lances from the wall member before striking said striking means so that said member engaging means firmly engages solid thicknesses of said structural members.
Claim 7
Dependent Claim
37 words
A method according to claim 2 further comprising the step of spacing said lances from the wall member before striking said striking means so that said member engaging means firmly engages solid thicknesses of said structural members.
