Abstract

Abstract The disclosure is directed to a floor box adjusting jack which can be employed to position a floor box with respect to a floor line in order to properly position, with respect to that floor line, a floor box cover plate. The jack of the invention is comprised of a base member having a threaded aperture therethrough through which is passed a threaded rod such that when the rod is rotated in contact with a subsurface below the floor line the base member will be raised, or lowered, in accordance with the direction of turning of the rod. Coupled to the base member are a plurality of upwardly extending arms each terminating in a floor box receiving cavity. The floor box receiving cavities are positioned adjacent the lower ends of a floor box. By initially positioning the threaded rod with respect to the subsurface the floor box may be raised, tilted, or raised and tilted, in order to properly align its top surface with the floor line. After the jack has been employed to properly position the floor box the floor box will be locked in place and the jack may then be removed through the floor box to be used with other floor box devices or left in the box as a support.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 187 words
A removable floor box jack for adjusting the position of an in floor floor box with respect to a floor line, comprising: a substantially elongated base member having a threaded aperture intermediate the ends thereof, and first and second arms coupled to opposite ends of said base member and and extending outwardly therefrom in generally oblique angular relationship therewith, the free ends of said first and second arms in opposing spacedapart relationship and formed to provide a floor box receiving cavity at each of said free ends to engage and laterally confine therebetween associateD opposing upstanding sides of said floor box; a threaded rod engaging said threaded aperture in said base member; said threaded rod having a first end to engage a first surface and a second end formed to accept a drive member for rotating said threaded rod and positioning said base member accordingly; whereby the rotation of said threaded rod causes said base member, said first and second arms and a floor box laterally confined between said first and second arms to be displaced substantially axially parallel to the longitudinal axis of said threaded rod.
Claim 2
Dependent Claim 187 words
A removable floor box jack for adjusting the position of an in floor floor box with respect to a floor line, comprising: a substantially elongated base member having a threaded aperture intermediate the ends thereof, and first and second arms coupled to opposite ends of said base member and and extending outwardly therefrom in generally oblique angular relationship therewith, the free ends of said first and second arms in opposing spacedapart relationship and formed to provide a floor box receiving cavity at each of said free ends to engage and laterally confine therebetween associateD opposing upstanding sides of said floor box; a threaded rod engaging said threaded aperture in said base member; said threaded rod having a first end to engage a first surface and a second end formed to accept a drive member for rotating said threaded rod and positioning said base member accordingly; whereby the rotation of said threaded rod causes said base member, said first and second arms and a floor box laterally confined between said first and second arms to be displaced substantially axially parallel to the longitudinal axis of said threaded rod.
Claim 3
Dependent Claim 33 words
A jack, as defined in claim 1, wherein said cavities each have a first wall which extends parallel with the base of said floor box and a second wall which extends perpendicular thereto.
Claim 4
Dependent Claim 19 words
A jack, as defined in claim 1 wherein said second end of said threaded rod has a slot therein.
Claim 5
Dependent Claim 34 words
A jack, as defined in claim 1, wherein said second end of said threaded rod is selectively flatted to permit said threaded rod to be rotated by use of a wrench or similar tool.
Claim 6
Dependent Claim 74 words
A jack, as defined in claim 1, wherein the structure comprising said jack may be positioned in oblique angular relationship to said first surface and said threaded rod selectively rotated, wherein a floor box laterally confined between said free ends of said first and second arms may be raised or tilted as said base member traverses said threaded rod; and wherein said base member is removable from said floor box without the repositioning thereof.
