ADJUSTABLE STOOL.

Application filed February 6,1925. Serial No. 7,232.

This invention relates to a stool adapted to be used in connection with atable, work bench, kitchen cabinet or the like, and the principal object of the invention is: to pro-' vide a seat which can be moved from a posi-. tion where it is used as such to a position below a table or cabinet, or where it will be out of the way from its position as a seat; a further object is to provide a seat or stool which can be adjusted in height; another object is to provide a swinging support from which the stool may be easily disengaged whenever desired; a still further object is to provide a mounting for the seat and stool 'which automatically raises it from engagement with the fioor as soon as'a person arises froin the seat. Other objects will appear hereinafter.

In the accompanying drawing, Fig. 1 illustrates the invention as applied to an ordinary table or cabinet; Fig. 2 is an enlarged view of one of the mounting members; Fig. 3 is a section of a post clamp; and Fig. 4 is a detail of the supporting post.

In carrying out this invention a hlnge 5 is secured by fastening screws or the like to a vertical support or post 6 of a table or cab net 7 usually having a lid or top 8. A swinging support 9 has hinged parts 10 at one end which register with the fixed hlnge member 5 so that a pivoting bolt 11 can be Inserted for fastening them together. At the other end of the supporting member 9 are spaced.

hooks 12 with corresponding notches 13, normally disposed in an upright or vertical position.

The stool proper comprises a tubular stem 1& with a stamped base plate 15 at the lower end, and a collar member 17 at the upper end which is threaded or pressed firmly into the.

end of the stem 14, and provides a continuous abutment or head 18 which projects outwardly beyond the tubular stem 14. A supporting sleeve 19 is provided which fits loosely around the stem 14 adjacent the top thereof held in place by a pair of spacing rivets 20 which hold the extremities 21'of the member a slight distance apart equal at least to the thickness of the hooks 12 of the mounting member 9. The rivets 20 are the same distance apart as the notches 13 so that the supporting stem 14 will slide freely through the sleeve 19 but without any undue looseness therein. Interposed between the upper end of the sleeve and the projection 18 of the collar 17 and surrounding the stem 14; is a spring 22 which tends to raise the supporting stem from the sleeve, and the hinging support is-mounted atsuch a height that normally the base plate 15 of the stem height of the stool may be adjusted by rotating the seat and the baseof the stool is always ralsed free from engagement with the floor as soon as a person arises therefrom by the 14: will be raised from the floor a slight disaction of the-spring 22. The base plate is made sufficiently large so that the stool will stand by itself so that it does not rock or wabble when in use besides being supported by the sleeve 19 and the supporting member 9. If it is desired, the stool may be easily disconnected as a unit from the supporting member 9 by simply lifting the sleeve 19 from engagement with the notches 13 of the hooks 12. The stool may then be used separately and the base 15 is sufficiently large to hold it in upright position on any substantially fiat or plane surface. The supporting member 9 may also be disconnected from'the hinge member 5 by simply removing the pivoting bolt 11.

I claim:

1. A stool comprising a hollow stem, a threaded collar member at the upper end 'thereof, a seat having a threaded stem adjustable in-the collar member, a movable support comprising a sleeve in which the hollow stem is vertically slidable and a spring surrounding the hollow. stem above the sleeve and engaging'it and the collar tending to raise the stool with respect to the collar.

2.
