Indexing furniture glide

Claim 2

An adjustable indexing glide for a hollow leg of an article of furniture comprising a nut, a box housing carrying said nut non-rotatably at its lower end and having side walls upstanding from said lower end adapted to make fastening engagement with the inner surface of the lower end portion of said hollow leg so as to mount the nut fixedly therein, a stud having a lower threaded portion engaged in the nut and having an upper unthreaded portion provided with opposed flat surface areas, and a foot non-rotatably fixed on the lower end of the stud and adapted to project from the lower end of the leg, said box housing having at its upper end spring finger means inwardly extending toward the stud and being resiliently biased against the flat surfaces thereof, thereby yieldably opposing rotation of the stud and indexing the degree to which the stud penetrates the nut on rotation therein and hence the extent to which the foot projects from the leg.

Claim 3

An adjustable indexing glide as claimed in claim 1 in which the box housing is formed from a single piece of spring sheet metal, having sides defining a shape corresponding to the cross sectional shape of the leg bore, and having barbs struck out from said sides for making said fastening engagement with the inner surface of the hollow leg.

Claim 4

An adjustable indexing glide as claimed in claim 1 in which the box housing is fastened in the leg against upward movement therein by a washer carried by the nut with its periphery underlying the bottom of the leg and in engagement therewith, and against downward movement in the leg by barbs struck out from the side walls of the housing and engaged with the inner surface of the leg.

Claim 5

In an adjustable indexing glide for a hollow leg of an article of furniture, a box housing mounting a nut into which a stud having a terminal foot is threaded for adjustable protrusion from the lower end of said leg, and means securing said housing in said leg comprising a plurality of side walls each adapted to be positioned in close parallelism to a portion of the surface of the bore of said hollow leg, and a plurality of barbs struck out from each of said side walls for biting engagement with said bore surface, each barb comprising an obliquely downwardly directed tab having its distal edge centrally indented to provide sharp points at the outer corners of the tab.

Claim 6

In an adjustable indexing glide for a hollow leg of an article of furniture, a box housing mounting a nut into which a stud having a terminal foot is threaded for adjustable protrusion from the lower end of said leg, and means securing said housing in said leg comprising a plurality of side walls each adapted to be positioned in close parallelism to a portion of the surface of the bore of said hollow leg, and a plurality of barbs struck out from each of said side walls for biting engagement with said bore surface, each barb comprising an obliquely downwardly directed tab having its distal edge centrally indented to provide sharp points at the outer corners of the tab.

Claim 7

An adjustable indexing glide for a hollow leg of an article of furniture comprising a nut, a box housing formed from a single piece of spring sheet metal having a bottom portion mounted non-rotatably on the nut and having side walls adapted to make fastening engagement with the inner surface of the lower end portion of said hollow leg so as to mount the nut therein, opposite end portions of said bottom portion being upturned to form a first opposed pair of said side walls of the housing, and opposite side portions of each of said first pair of side walls being inturned to form half portions of a second opposed pair of said side walls of the housing, whereby the housing is rectangular in cross section and has an open top and closed bottom, a stud having a threaded portion engaged in the nut and having an unthreaded portion provided with opposed flat surface areas, a foot non-rotatably fixed on the lower end of the stud and adapted to project from the lower end of the leg, and upper extensions formed on each of said first named pair of opposed side walls having their lateral end portions inturned to form spring finger means inwardlY extending toward the stud and being resiliently biased against the flat surfaces thereof, thereby yieldably opposing rotation of the stud and indexing the degree to which the stud penetrates the nut on rotation therein and hence the extent to which the foot projects from the leg.

Claim 8

An adjustable indexing glide for a hollow leg of an article of furniture comprising a nut, a box housing formed from a single piece of spring sheet metal having a bottom portion mounted non-rotatably on the nut and having side walls adapted to make fastening engagement with the inner surface of the lower end portion of said hollow leg so as to mount the nut therein, opposite end portions of said bottom portion being upturned to form a first opposed pair of said side walls of the housing, and opposite side portions of each of said first pair of side walls being inturned to form half portions of a second opposed pair of said side walls of the housing, whereby the housing is rectangular in cross section and has an open top and closed bottom, a stud having a threaded portion engaged in the nut and having an unthreaded portion provided with opposed flat surface areas, a foot non-rotatably fixed on the lower end of the stud and adapted to project from the lower end of the leg, and upper extensions formed on each of said first named pair of opposed side walls having their lateral end portions inturned to form spring finger means inwardlY extending toward the stud and being resiliently biased against the flat surfaces thereof, thereby yieldably opposing rotation of the stud and indexing the degree to which the stud penetrates the nut on rotation therein and hence the extent to which the foot projects from the leg.
