STUD EXTENDER INTERLOCK
BACKGROUND OF THE INVENTION
This invention relates to an extendable metal stud and more particularly to a structure including an extendable metal stud, a floor track for attachment to the bottom of the stud, a ceiling track for receivinq the top of the stud and means for affixing the telescoping portions of the extendable stud in a fixed extencled condition.
U.S. Patent No. 3,492,766 discloses an extend-able steel stud, to compensate ~vr variations in height between the floor and the ceiling. The standard stud body is channel shaped and has a stud extender or adaptor which effectively makes the stud suitable for use throughout a range of varying heights. The stud extender is slidably disposed within the top portion of the channel shaped standard stud body. To use the stud extender, a person must reach up, high above the head, or climb a ladder, and manually grasp the stud extender, pull it up, while holding the stud body down with the other hand. The top of the stud extender is guided into a ceillng track, and means are then used to affix the stud body and stud extender in the relatively elongated relationship.
An extendable stud with means for extending it with greater ease and requirin~ less time would provide substantial cost savings in the erection o a building with a great number of partition walls.

1 31 OgO3 SUMMARY OF THE INVENTION
The present invention includes a channel shaped standard stud body with a stud extender in the bottorn end of the stud body. The stud extender has notched webs which are formed to easily engage a top flange on a floor track, whereby a person can affix the stud extender to the floor track while standing beside the floor track.
The engagement o~ the stud extender with the floor track is such that when the stud body is moved, following engagement, to a vertical position, the stud body can be moved vertically upward into a downwardly opening ceiling track without disengaging the stud extender from the floor track. The stud extender thus slides partially out from the stud body as the stud body is moved vertically upwardly.
When the stud body has been moved vertically into the ceiling track, the stud body and the stud extender are mechanically af~ixed to prevent ~urther relative movement, as by a self-tapping screw inserted into the two overlapping parts.
It is an object of the present invention to provide an improved extendable metal stud for use in hollow partitions.
It is a further object of the invention to provide an extendable metal stud having means or engag-ing a floor track, ~or easy adjustment of the length o the extendable stud, ~or use in constructing a first wall, and suitable for removing from such first wall for reuse in a second wall of somewhat dlfferent height.
1 " ~3 It is a still further object to provide a floor track and vertical stud combination which provides improved access for utilities along the extent of the floor track and from there up into the hollow between the hollow wall opposed wallboards.
These and other objects and advantages of the invention will be more fully apparent when considered in relation to the preferred embodiments thereof as set forth in the specification and as shown in the dr~wings in which:

DESCRIPTION OF THE PREFERRBD EMBQDIMBNTS
Referring to Fig. 1, there is shown the bottom portion of an extendable U-stud 10, which consists essentially of a channel shaped elongate formed sheet metal stud body 12 and a short, channel shaped formed sheet metal stud extender 14, telescopically disposed within the channel shaped stud body 12.
The stud body 12 includes a solid face 16, a ", pair of spaced parallel webs 18 extendlng perpendicularly from the solid face 16, and a pair of inwardly directed ~langes 20 forming the face of the stud opposite to the solid ace 16. Th~ stud extender 14 includes a solid face 22, a pair of spaced parallel webs 24~ and a pair of nwardly dlrected flanges 26, all sufficiently smaller than the corresponding parts of the stud body 12 such that the stud extender 14 fits somewhat tightly within the bottom end of the stud body 12.
The two webs 24 o~ the stud extender each have a bottom end 28 which is cut to ~orm an interlocking slot 30 exkending upwardly thereinto, formed to interlock with the floor track 32, as shown in Fig. 2.
1 31 0~03 Floor track 32 includes an upwardly opening channel 34 having a bottom wall 36 and two sidewalls 38.
Extending upwardly ~rom the center of the bottom wall 36 i5 a relatively strong, solid central vertical wall 40 with a relatively widened, elongate head 42 along the top of the central vertical wall 40. The widened head 42 is preferably a pair of opposed, elongate flanges 43, which permit engagement o~ an extendable stud 10 from either side of the ~loor track 32, as will be explained herein-after.
Interlocking slot 30 has a shape which includesa wide bottom opening 44 tapering down to a relatively narrow neck 46 and a wider head area 48, ~ormed by a protruding tongue 50 on one side, which creates the narrow neck and the wider head. The wide bottom opening 44 permits the floor track head 42 to be placed above tongue 50, ~hen the stud 10, and thus the slot 30, are at an angle, between about lOQ and about 50 to the verti-cal~ and relative to the floor track 32. If the floor track head g2 i5 above the tongue 50 as the stud is moved to a ~ertical position, the floor track head 42 becomes locked above the ton~ue 50, as shown in Fig. 3.
At the top o~ wider head area 48 o~ each slot 30 is a bent-out tab 51j ~ormed ~rom the sheet`metal which lS removed, by partial cutting and bendingr to form the 510t head area 4q. Tabs 51 are disposed at a 90 angle to the plane o~ each web 2g. Tabs 51 provide two functions. Tabs 51 limit the movement of stud extender 1~ into stud body 12r such that the bottom end 28, with slot 30, is always protrudincJ out oE stud body 12 su~
cient ~or lnitiating the interlocking engagement of 1 31 00~)3 floor track 3~ with slot 30. Tabs 51 also provide a greater area of engagement of the stud extender 14 with the floor track head 42, for improved support of the extendable stud 10.
Figs. 4, 5 and 6 each show the stud 10, 100r track 3~ and a downwardly opening ceiling track 52, in progressive steps as (1) the stud extender slot 30 is placed on floor trac~ head 42 and the stud is moved to the vertical, ~2) the stud body 12 of stud 10 is moved upwardly as the stud extender 14 is held down by the engagement of the slot 30 on the floor track head 42, and (3J with the stud body 12 fully raised into the ceiling track 52, the stud body 12 and the stud extender 14 are mechanically affixed together, by a self-drilling, self-tapping screw 54 extending through overlapping portions of the stud body 12 and the stud extender 14.
Also shown in Fig. 2 is a sheet of gypsum wallboard 56 disposed with a bottom edge 58 located within the channel 34 of floor track 32, and with an inner or back face 60 disposed against the solid faces 16 and 22 of stud body 12 and stud extender 14, respec-tively. The wallboard normally forming the opposite side of hollow partition wall 62 is not shown. Also shown is an electrical cable 64 extending along the channel 34 and upward from channel 34 to between the back ~ace 60 of wallboard 56 and the head 42 of floor track 32, showing how electrical cable can be disposed along a floor track and extend therefrom up into the hollow of a partition wall 62, behind the wallboard 56.
