INCLINABLE ROCKING CHAIR Filed Nov. 14, 1966 a'lfig IZEENTOR.
United States Patent 3,403,882 INCLINABLE ROCKING CHAIR Artur Reinhold Lindqvist, Grythyttan, Sweden, assignor to AB Grythyttans Stalmobler, Grythyttan, Sweden, a corporation of Sweden Filed Nov. 14, 1966, Ser. No. 593,790 6 Claims. (Cl. 248373) ABSTRACT OF THE DISCLOSURE The present invention refers to an inclinable chair which can be made to rock, its seat part being mounted on a horizontal axis in swinging relationship to its leg support structure, the connecting element comprising a resilient torsion bar, the ends of which are secured to the leg structure, while its center portion is secured to the seat part, whereby the leg structure is provided with at least one cylindrical body, the center axis of which substantially coincides with the fixed pivot of the torsion bar, and upon which a bearing box secured to the seat part is abutting said bearing box embracing a maximum of 180 of the circumference of the cylindrical body.
The object of the present invention is to provide a chair having the characteristics mentioned, the seat and leg structure parts being readily separable in order to facilitate storage and transportation. This readily separable feature allows the rocking chair to be knocked down and stored between uses, thus enabling rocking chair comfort to be afforded to situations where heretofore only straight back folding chairs or the like have been practical. While such a knockdown feature may only be desirable in some situations, it is critical in others where a floor space may be used a portion of the time for ambulatory purposes such as dancing or sport events and at other times for the seating of an audience, and storage space is limited.
An example of an embodiment of the invention will be described below with reference to the accompanying drawing in which:
FIG. 1 is a side elevational view of a chair according to the invention, and
FIG. 2 is a sectional view of the bearing arrangement of the same chair in enlarged scale taken substantially along the line II-II in FIG. 1.
A chair according to the present invention comprises a seat part 1 and a leg structure support 2 (and a supporting leg structure 2), in the embodiment described as an example, made of metal tubing. The seat part 1 consists of a frame structure of bent tubes framing in the seat and the support for the back. The seat and the back support are made of wooden ribs 3 and 4, respectively, which by means of screws are fastened to two metal bars 5, 6, respectively 7, 8 which extend below the seat and behind the back of the chair and are welded to the laterals of its framework. A pair of wooden arm rests (elbow rests) 9, 10 are secured to the laterals of the back of the chair being supported by bars 11, 12 extending from the side portions of the seat. The leg structure of the chair comprises two pairs of legs 13, .14 made by bending a piece of tube at its center portion to form a short are 15, so that the end parts extend in an angular approach. The two pairs of legs 13, 14, interconnected by transversal tubes 16, 17, are positioned at each side of the seat part right under the lateral seat tube 18, whereby a space is provided between the arc portion of the lateral tubes 15 of the leg structure and the lateral seat tube 18. Immediately below each arc portion 15 of a pair of legs a plate 19 is welded between the legs. A cross member 20 3,403,882 Patented Oct. 1, 1968 "ice connects the pairs of legs. In the preferred embodiment of the invention the cross member 20 is a torsion rod'of spring steel and, as shown in the drawing, is welded at its ends to the plates 19.
A bar plate 21 is welded onto the top of the spring rod 20 at its center portion, said bar plate extending perpendicularly to the rod and being secured with screws 22 or other suitable means to bars 5 and 6, which extend under the seat supporting seat ribs 3. Seat part 1 of the chair and leg structure 2 are thus connected by bar plates 21 secured to spring rod 20, and can be readily taken apart by untightening nuts 22 of the screws. Seat part 1 and leg structure 2 may then be stacked separately or in each other facilitating storage and transportation.
At each one of the ends of torsion bar 20 adjacent to leg structure 2 a cylindrical body 23, made of nylon as a suitable material and having comparatively short axial extension, is secured to the rod, the center axis of said body 23 substantially coinciding with the fixed pivot of the torsion bar. Bars 11, 12 supporting the elbow rests, are bent in between tube 18 of the seat frame and are 15 of the leg structure 2 and continue downwards towards the cylindrical body, being fitted with a bearing box part 24 at their respective ends, said bearing box exhibiting a curvature substantially corresponding to the peripheral outline of the cylindrical body, its embrace extending over slightly less than one half of the circumference of said cylindrical body 23. For the manufacturing process, it may be convenient to have the inside curvature of the bearing box of a slightly larger radius than the one of the circumference of the cylindrical body 23. The axial extension of the bearing box may suitably be less than the one of the cylindrical body.
When using the chair, the bearing box parts, secured to the seat, follow the peripheral surface of the cylindrical bodies. When the steel rod 20 is subjected to torsion it tends to cause the seat to return to a horizontal position. A gentle and pleasant rocking movement is thereby obtained.
What I claim is:
1. A knockdown rocking chair comprising in combination:
a seat structure,
said seat structure having bearing means secured therebeneath adapted to rest upon and pivot about support means, and
a stationary leg structure including:
two pairs of legs interconnected by a substantially horizontal cross member,
support means positioned on said leg structure l upon which said bearing means is adapted to rest and about which said seat structure is adapted to pivotally rock,
a plate member fixedly secured transverse to said cross member whereby alternating pressure upon said transverse plate member, caused by the rocking motion of said seat structure, will cause said cross member and transverse plate member fixedly secured thereto to rotate through partial revolutions on a common axis,
said transverse plate member having attachment means adapted to releasably secure said seat structure to said stationary leg structure whereby said rocking chair may be quickly and easily assembled or broken down.
2. A knockdown rocking chair as claimed in claim 1 wherein said transverse plate member is a bar and said cross member is a torsion rod.
3. A knockdown rocking chair as claimed in claim 2 wherein said support comprises at least one cylindrical body secured about said torsion rod, proximate the ends thereof; said cylindrical body having an axis substantially aligned with the axis common to said torsion bar and plate means.
4. A knockdown rocking chair as claimed in claim 3 wherein the bottom surface of said bearing means is adapted to mate with and rest upon said at least one cylinder body, said bottom surface exhibiting a curvature substantially corresponding to the circumferential surface of said at least one cylindrical body.
5. A knockdown rocking chair as claimed in claim 4 wherein the maximum curvature of said bottom surface is through cylindrical arc of 180.
6. A knockdown rocking chair as claimed in claim 5 wherein said at least one cylinder body is composed of nylon.
