Abstract
A support and gliding mechanism for a chair or sofa includes a base; an elongated, generally U-shaped support arm on the base; a three-sided end housing pivotally mounted on each free end of the support arm, the housing having inverted triangular sides and a rectangular end extending between outer edges of the sides; and a generally rectangular chair support frame defined by side walls, the bottom corners of which are pivotally connected to the bottom corners of the housing sides, the result being a closed structure covering most of the base even during gliding.
Description
- 1. Field of the Invention
- This invention relates to a support and gliding mechanism for a chair or a sofa.
- 2. Discussion of the Prior Art
- Rocking and gliding mechanisms for chairs or sofas of the type described herein are disclosed, for example in U.S. Pat. No. 5,427,433, issued to R. E. Holobough Jr. on Jun. 27, 1995; U.S. Pat. No. 5,947,557, issued to P. Bellefleur on Sep. 7, 1999 and U.S. Pat. No. 6,092,870, issued to C. Desnoyers et al on Jul. 25, 2000, and US Patent Application No. 2003/0015900, published on Jan. 23, 2003.
- A problem with some currently available mechanisms of the type disclosed by the above-identified patent literature is that the mechanisms, which can be unsightly, are often visible beneath the seat portion of the chair or sofa. Manufacturers often go to considerable expense to hide such mechanisms. Moreover, the mechanisms can be quite complex and/or large, involving many components.
- One attempt to give a mechanism of the type in question more eye appeal is found in U.S. Pat. No. 6,092,870, which issued to C. Desnoyer et al on Jul. 25, 2000. The Desnoyer et al chair support mechanism is somewhat bulky and the base of the chair is still visible during rocking.
- An object of the present invention is to provide a solution to the above mentioned problems in the form of a relatively simple, compact and aesthetically pleasant support and rocking mechanism for a chair or sofa.
- Accordingly, the invention relates to a support and gliding mechanism for a chair or sofa comprising:
- (a) a base for supporting the mechanism on a horizontal surface;
- (b) an elongated support arm on said base having a pair of upwardly extending free ends;
- (c) a pair of end housings, each said housing including:
-
- (i) side panels pivotally connected to the free ends of said support arm for rotation around horizontal axes extending between top, outer corners of the side panels, and
- (ii) an end panel extending between outer side edges of the side panels, said end panels defining end walls of the mechanism; and
- (d) a chair support frame including:
-
- (i) a pair of side walls having bottom corners pivotally connected to bottom corners of said side panels, whereby said side walls can rotate around horizontal axes extending transversely of the mechanism between the bottom corners of the side panels, and
- (ii) a first crossbar extending between top edges of the side walls for supporting a chair or sofa.
- The invention is described below in greater detail with reference to the accompanying drawings, which illustrate a preferred embodiment of the invention, and wherein:
-
FIG. 1 is an isometric view of a support and gliding mechanism in accordance with the present invention; -
FIG. 2 is a top view of the mechanism ofFIG. 1 ; -
FIG. 3 is a side view of the mechanism ofFIGS. 1 and 2 ; -
FIG. 4 is an end view of the mechanism of FIGS. 1 to 3; -
FIG. 5 is a cross section taken generally along line 5-5 ofFIG. 4 ; and -
FIGS. 6 and 7 are side views of the mechanism of FIGS. 1 to 5 at the ends of a gliding action. - Referring to the drawings, the support and gliding mechanism of the present invention is mounted on a base, which includes a
circular baseplate 1 and apost 2. Thebaseplate 1 can be connected to a turntable or other large, circular base, and the post can be extensible, i.e. telescopic, usually, as is conventional in existing gliders or rocking chairs of the type disclosed herein, thebaseplate 1 and thepost 2 are solid, one-piece elements. - An
elongated support arm 3 is mounted on the top end of thepost 2. As best shown inFIG. 5 , thesupport arm 3 is generally U-shaped with a flat,horizontal center section 5, and a pair of inclined, upwardly and outwardly extending end sections 6. Asleeve 7 is welded to the outerfree end 8 of each arm section 6. - A three-sided end housing indicated generally at 10 is rotatably mounted on each
free end 8 of thesupport arm 3. Thehousing 10 includes a pair ofside panels 12, each of which defines an inverted triangle with a convexupper edge 13 and straight downwardly convergingside edges 14. Theouter side edges 14 of thepanels 12 are interconnected by arectangular end panel 15, which is integral with thepanels 12. Crossbars 16 (FIG. 2 ) extend between thepanels 12 near the bottom of theinner side edges 14 thereof.Bearings 18 in the ends of thesleeves 7 andbolts 19 extending through theside panels 12 into the bearings rotatably connect thehousings 10 to theends 8 of thearm 3. The axes or pivot points of thebearings 18 and thebolts 19 are at the top, outer corners of theside panels 12. -
Bearings 20 andbolts 21 pivotally connect the bottom corners of theside walls 22 of a chair supporting fame indicated generally at 23 to thehousings 10. Theframe side walls 22, which are generally rectangular, have a slightlyconcave bottom edge 25, and upwardly and inwardlyinclined ends 26. Awide flange 27 extends outwardly from the top edges of theside walls 22 for reinforcing theframe 23, i.e. to give the frame lateral rigidity. V-shaped notches 29 in the top center of theside walls 22 receive a laterally extendingangle iron 30. Theangle iron 30 is welded to theframe side walls 22 and theflanges 27. Theangle iron 30 and theflanges 27 support a rocking/gliding chair or sofa (not shown). Because one end of the mechanism is the mirror image of the other, eitherhousing 10 can form the front or rear end of the chair support. -
FIGS. 2, 6 and 7 illustrate the gliding action of the mechanism of the present invention. In the rest position of the mechanism (FIG. 3 ), approximately one-half of eachhousing 10 is covered by the side walls of thechair supporting frame 23. As illustrated inFIGS. 6 and 7 , during gliding, first one and then theother housing 10 is more or less fully exposed at the extremes of travel of thechair supporting frame 23. However, in every position of the chair, there are virtually no gaps visible from the exterior of the mechanism. Moreover, becausepost 2 is short, the top outer free ends 6 of thesupport arm 3 are a substantial distance above thecenter section 5 and thehousings 10 and theframe 23 are high, very little of thebase 1 is visible beneath theframe 23 even in the extreme end positions of the mechanism during gliding. Finally, thecrossbars 16 shown inFIG. 2 not only reinforce theend housing 10, but they act as stops for limiting movement of the supportingframe 23. At the extremes of movement of thesupport frame 23, thecrossbars 16 engage the bottom of thesupport arm 3.
