United States Patent 3,230,910 COMBINATION STOOL Per Erik Olssen, 42 Vastermalmsgatan, Eslriistuna, Sweden Filed July 6, 1964, Ser. No. 380,526 Claims priority, application Sweden, July 19, 1963, 8,023/63; Apr. 24, 1964, 5,089/ 64 4 Claims. (Cl. 108153) This invention relates to a stool comprising a few main parts with coupling members, adapted to be combined to a bar stool, table, etc., and easy to stow away when not being used.
There is a great number of proposals how to solve the problem of constructing a stool which is both durable and of lightweight, allows combination in different ways and requires little space when not in use. However, none of the constructions heretofore made succeeded in practice to meet the aforesaid requirements.
Tfn's invention has as its object to solve the problem of producing such a stool.
The invent-ion relates to a stool which comprises a few main parts and members for connecting the same. The invention is substantially characterized in that the main parts and details of the coupling members are designed as truncated cones having substantially the same conicity, and that two equal or two different stool parts can be combined with one another or that one stool part can be combined with another part of furniture known per se, in such a manner, that two equal or two different coupling members are used for connecting the parts, according to the type of furniture desired.
All parts are preferably made of a plastic material of high strength and toughness, rendering it possible to give the walls in the different parts of the stool optimum thinness, which makes the stool easier to stack, reduces its weight and, consequently, its manufacturing costs.
The invention will be described in greater detail in the following, reference being had to the accompanying drawings showing different embodiments of the invention.
FIG. 1 shows a cross-section of a stool assembled of two different stool parts, and
FIG. 2 shows in an exploded view a cross-section of the stool according to FIG. 1 with an intermediate portion mounted thereon.
As appears from the drawings, the stool part 1 is the foot which is placed with its larger base surface on the support. Said surface is in addition widened to funnel shape by an annular peripheral portion 2 providing a stable carrying surface. The upper smaller base surface of the foot part is provided with a downward tapering recess 3 defined by a bottom 4 with a central hole therein for a coupling member.
The stool part 5 which constitutes the seat part has at its larger base surface substantially the same diameter as the foot part, but its base surface is turned upwards. About the periphery of said surface preferably a flange 6 is provided, to the inside of which and in spaced parallel relationship therewith a second flange 7 preferably lower than flange 6 can be arranged. Said inner flange 7 is intended to support a disk or seat cushion 11 mounted inside of the outer flange 6, which cushion may be provided on its lower surface with a fastening clam-p or the like for a screw.
The disk or seat cushion 11 may, of course, be of such size that it projects outside of flange 7 and rests upon the same.
The smaller base surface of the seat part 5 which can be inserted into the recess 3 of foot part 1 has a central hole corresponding to the hole in bottom 4 of said reice cess, rendering it possible to lock the said two parts together by a coupling member.
According to another characterizing feature of the invention the stool is provided with an intermediate part 8 for increasing its height to a certain standard. Like the two other stool parts, the intermediate part is shaped like a truncated cone and has in its downward larger base surface a recess 9 which corresponds to the upper 'portion of stool part 1. The intermediate part 8 is mounted over said stool part, in such a manner, that the upper portion of the latter projects into the recess 9 and thereby increases the height of the foot part.
In the smaller lower base surface of the intermediate part 8 a second conical recess 10 is arranged which corresponds to the lower portion of the seat part 5. The said lower portion can be inserted in the foot part thus extended which results in a stool considerably higher than before.
Due to the fact, that all stool parts are preferably made of normally flexible plastic material, in this first embodiment all parts will be wedged to another after their assembly. For separating the parts, one of the parts is to be turned somewhat relative to the other part at the same time as it is pulled therefrom. In this way, the parts separate very easily from one another.
When a stronger connection between the said parts is required, a coupling member can be inserted in the holes provided in the parts for this purpose. It is also possible to lock the seat cushion 11 together with the remaining parts, for example by means of a long lock-pin in combination with the fastening clamp on the lower surface of said cushion.
Thanks to the particular strength and toughness of the material, the walls in the different stool parts can be made thin, for example 2.5 mm., which means that about stool feet can be stacked one above the other without producing a stack higher than about 2 m. The remaining stool parts are stacked in a corresponding manner.
It appears from the aforesaid that a great number of stools constructed according to the aforedescribed embodiment of the invention, can when not in use be stowed away in the form of stacks with a minimum of space requirement.
What I claim is:
1. A stool assembly comprising an upstanding base having an upwardly opening recess, a stool member having an intergrant depending post freely telescopically received in said recess, said recess and depending post being in the shape of truncated cones to be wedged in each other and having a vertical dimension greater than its major diameter for providing lateral stability wherein said base is truncated cone-shaped with an outwardly flared lower end for engaging a large area of a supporting surface.
2. The stool assembly as defined in claim 1 wherein said stool member is inverted truncated cone-shaped with an outwardly flared upper end, and a cushion supported on the upper end of said stool member.
3. The stool assembly as defined in claim 2 wherein the upper end of said stool member includes in upstanding peripheral flange receiving said cushion, and an upwardly extending annular flange disposed inwardy of and below the peripheral flange engaging the bottom of the cushion.
4. The stool assembly as defined in claim 2 together with an intermediate member having a downwardly opening recess of truncated cone-shaped free-1y telescopically engaged over the upper end of the base, said intermediate member having an upwardly opening recess of truncated cone-shape substantially identical to the recess in the base.
