ATTORNEY United States Patent 3,003,730 CANTILEVER COUNTER STOOL Paul L. Dodds, 1427 E. 6th St., Los Angeles 21, Calif. Filed June 12, 1959, Ser. No. 819,930 7 Claims. (Cl. 248220.5)

The present invention relates primarily to a cantilever counter stool of a construction wherein the stool structure may be aligned, plumbed and properly balanced in an easy and facile manner.

An object of the invention is the provision of a counter stool which permits the stool base to be properly positioned relative to a finished floor to the end that any tendency of the stool toward rocking movement is prevented.

One of the chief problems in the installation of a counter stool which utilizes a tubular support or leg, is the time and expense necessary for proper installation of the base member for said tubular support. If this base member and support are not properly balanced or leveled, the stool seat will not be properly carried thereby. The present invention overcomes this difficulty in a simple manner and installation of the present invention is easy of accomplishment with assured results.

. A further object is a design for a counter stool wherein the support or leg for said stool is so constructed and related to a foundation, and any step piece therefor, that cleaning of the floor is simplified as no obstruction is presented; Thus, mopping and sweeping time is reduced to a The present construction for the invention has been thoroughly tested after installation and no dimensional changes were noted nor was there any cracking, bending or any other defects in the structure.

Further objects include a counter stool construction which is inexpensive in cost of manufacture, easily installed, foolproof in operation and whichv gives superior resultstwithout the necessity of frequent repairs and one which is adjustable. 7

With the. above mentioned and other objects in view, the invention consists of the novel and useful provision, formation, construction, association and relative arrangement of parts, members and features, all as shown in one embodiment in the accompanying drawing, described generally and more particularly pointed out in the claims.

In the drawing: FIGURE 1 is a fragmentary, sectional view showing my improved construction in part embedded within a concrete fill;

- FIGURE 2 is an enlarged, transverse sectional view of the stool base and under structure therefor showing means of adjustment for said base;

FIGURE 3 is a fragmentary view looking in the direction of the arrow 3 of FIGURE 2;

FIGURE 4 is a sectional view, on an enlarged scale, on the line 4-4 of FIGURE 2; and,

' FIGURE 5 is a sectional view, on an enlarged scale on the line 55 of FIGURE 2.

In the drawing, I have shown in outline a counter 1 in front of which is the cantilever counter stool desig- 6 nated as an entirety by the numeral 2. In FIGURE 1 I have indicated in cross-section a concrete fill 3 of stepped form as shown at 4 and placed over said concrete is a covering such as a terrazzo material 5. This simple.

3,003,730 Patented Oct. 10, 1961 terrazzo covering is such as to have a kick or scufi board 6, a floor covering 7 with an intermediate step portion at 8. It will be noted that the floor line is indicated at 9, which may be countersunk at 10 to accommodate the terrazzo covering 7 so that the top of said covering 7 is in alignment with the floor line 9. Sometimes the terrazzo covering is not utilized as shown in FIGURE 2, and in this case the floor line would extend outwardly at a uniform height.

The cantilever counter stool designated generally as 2 includes a seat 11 having a back 12 although it is obvious that other types of seats may be utilized, and as a rule, the seat is rotatable. To support the seat 11, I have provided a leg or support tube 13, which includes a vertical portion 14, a portion /15 substantially at an obtuse angle to the portion 14 and a base portion 16, the latter and the vertical portion 14 being in right angular relationship. Hence, if the base portion is properly placed within the concrete fill and is properly supported upon a floor, the tubular portion 14 will be vertical and will not cant in any direction. Thus the seat 11 will be balanced and normal to the tube portion 14 without tendency to rotate under gravity or to rock in any direction.

If the floor and particularly the floor line 9, is truly level, the installation of the present structure is quite The under structure for the tubular support tube 13 which includes the portions 14, 15 and 16, has a tubular sleeve 17 for telescopically receiving the base tube 16. The base tube 16 is open ended, as shown at 18 while the tube 17 is closed at its inner end 19 by one leg of an L-type bracket 20, the opposite end of tube 17 being open as shown at 21. Tube 17 is provided on its undersurface with a Z-type bracket 22. The brackets 20 and 22 are welded or otherwise secured to the tube 17 and the brackets support the tube at equal height above the feet 23 and 24 of said brackets. As shown in FIGURE 4, both tubes 16 and 17 are substantially square in cross section. This construction prevents relative rotation between the two tubes. Obviously, other forms of tubes may be used, such as rectangular, triangular, oval, or even keyed structures, however, I have found that a square section performs satisfactorily. Assuming that the floor, and particularly floor line 9 is level, the feet 23 and 24 of the brackets 20 and 22, are anchored to the floor by means of bolts, as shown in FIGURE 2 at 25 and 26. Thus the contractor or installer is assured that tube 17 is level if the floor is level. Referring again to FIGURE 2, it will be observed that the portion 16 of the tubular leg or support 13 is received within the tube :17 and in v the present instance this distance is such that the outer end 21 of tube 17 is adjacent the point of joinder of portion 16 with portion 15. The portion 15 is reinforced by an internal tube 27 having the same cross sectional form as the tubular portion 15. A tube 28 is received within the tube portion 16 and has a cross section identical with tube 16. The upper wall portion of tube 28 extends across and closes the angled end of tube 27 While the opposite parallel wall portion of said tube 0 terminates adjacent the inner surface of the tube 15 where it joins with the tube 16. At this zone the tube 15 is provided with an opening 29 to permit access within tube 28. Tube 28 extends for a short distance within tube 16. Within the tubular portions 16, 17 and 28, is means for locking the tubular members together in working relationship and against movement, as well as permitting adjustment of said members so as to permit separation therebetween. This means includes a nut 30 which has a square sectioned, tapered sided head 31, as shown in FIGURE 5, the nut having an elongated shank 32 joined to the head with said shank and head formed with axial bore 33, the shank terminating in a reduced diameter screw threaded bore 34 co-axial with bore 33. Forward of the. end of the shank is a conical member 35 provided with an axial bore 36. An annular abutment member 37 is secured transversely within the tube 28 and forwardly of the conical member 35. A bolt 38 having a head 39 and an elongated shank 40. has the head positioned on one side of the annular abutment member 37 while the shank 40 is passed through said annular abutment and the axial bore of the conical member 35 for threaded engagement with the threads 34 of the shank 32 of nut 30.

The operation, uses and advantages of the invention just described, are as follows.

The installer of the present cantilever counter stool first determines if the floor to which the base tube 17 is to be attached is level, and if not level, shims may be used so that when the brackets 20 and 22 are fastened to the floor, as illustrated in either FIGURE 1 or 2, the base tube 17 is level. The bolts 25 and 26 are inserted through openings in the foot portions of the brackets and into the concrete floor. As the brackets support the base tube in a level position, all that is necessary to do thereafter is to insert the remaining portions of the tubular legs or supports in said base tube. This is accomplished by partially releasing the bolt 38 from the nut 30 so that tube 16 and associated tubes 15, 27, 28, together with the nut 30 and cone 35, maybe received within said base tube 17, as illustrated in FIGURE 2, whereupon having adjusted the position of the seat 11 relative to the counter 1, the workman applies a suitable tool through the opening 29 of tube 15 and turns the bolt 38 to cause tight engagement with the nut 30. Such tightening causes the tapered surfaces of the head 31 to engage both the tubes 16 and 17, the head 31 partially entering the tube 16. At the same time the end of the shank 32 of nut 30 abuts the cone 35 for wedging engagement between tubes 16 and 28, the cone partially entering tube 28, as shown. In this way all portions of the tubular' structure are locked against shifting movement. The nut 30 will not rotate when the bolt 38 is turned due to the fact that the head 31 is square in cross section as shown in'FIGURE 5. i

The construction illustrated allows for rapid installation. As shown in FIGURE 1, the seat 11 is'provided with a stud 41 having a cam end 42 which cam' is adapted to engage a transverse pin 43 carried within the tube sup port member 14. Thus any rotation of the seat from the position illustrated in FIGURE 1, will, through'the medium of the camand pin, re-rotate the seat to the position shown.
