ATTORNEYS IGEVORGEML LINGLE Jan. 1]., 1955 w. LINGLE RESILIENTLY MOUNTED ANGULARLY ADJUSTABLE CHAIR Filed Feb. 12, 1954 a BY a/uz'ahm United States Patent RESILIENTLY MOUNTED ANGULARLY ADJUSTABLE CHAIR George W. Lingle, Statesville, N. C. Application February 12, 1954, Serial No. 409,909 3 Claims. (Cl. 155-55) This invention relates to a chair and more particularly to a chair capable of being adjusted to a selected position between a full reclining position and an upright sitting position.
Another object is to enable the occupant of the chair to select the position desired and to lock the chair in the selected position while remaining in the chair seat.
The above and other objects may be attained by employing this invention which embodies among its features a platform adapted to rest on a supporting surface, resilient loops carried by the platform and extending upwardly from the front thereof adjacent opposite sides of the platform, arms carried by the loops and extending rearwardly therefrom above opposite sides of the platform, a seat mounted on the arms for movement in an arcuate path above the platform from an upright sitting position to an inclined reclining position, a curved post carried by the platform and extending upwardly therefrom beneath the seat and a clamp carried by the seat and engaging the post for holding the seat in a selected position in its arcuate path.
Other features include a handle carried by the seat adjacent one side thereof and operatively connected to the clamp for engaging or disengaging the clamp with the post whereby the occupant of the chair may release the clamp, and move the seat to a selected position in which it may be retained by tightening the clamp.
In the drawings:
Figure 1 is a perspective view of a chair embodying the features of this invention;
Figure 2 is a bottom plan view of the chair illustrated in Figure 1;
Figure 3 is a sectional view taken substantially on the line 33 of Figure 1, showing the chair in its upright sitting position;
Figure 4 is a view similar to Figure 3, in its full reclining position;
Figure 5 is an enlarged fragmentary sectional view taken substantially on the line 55 of Figure 4; and
Figure 6 is a fragmentary enlarged sectional view taken substantially on the line 6-6 of Figure 4.
Referring to the drawings in detail, a pair of spaced side bars 10 carrying intermediate their ends a transversely extending cross bar 12 which with the side bars 10 define a platform designated generally 14. Carried by and extending downwardly and outwardly from the ends of the side bars 10 adjacent the rear of the platform are feet 16 and secured to the side bars 10 and extending downwardly and forwardly therefrom are resilient loops 18, the lower portions of which define feet which are adapted to engage the supporting surface and cooperate with the feet 16 in maintaining the platform 14 in spaced relation to the surface. The loops 18 after defining the feet 20 extend upwardly, as illustrated in the drawings, to define adjacent opposite sides of the chair resilient legs 22 carrying at their upper ends spaced arms 24 which extend rearwardly above the side bars 10, as will be readily understood upon reference to the drawings.
A chair frame designated generally 26 comprises side members having seat and back rails 28 and 30, respectively, which side members are joined adjacent their opposite ends by cross members 32 and 34, and extending transversely between the seat rails 28 near their junctions with the back rails is a cross bar 36. Carried by and extending between the seat rails 28 and back rails 30 on the upper sides thereof is a cushion defining a seat showing the chair 2,699,200 Patented Jan. 11, 1955 38 and a back 40 of the chair. It will thus be seen that a hollow box-like structure is provided beneath the seat 38 of the chair and carried by the cross member 36 and extending outwardly therefrom are clamp jaws 42 and 44 which jaws are pierced with aligning openings 46 for the reception of a screw-threaded shaft 48 which extends through one of the side members and is provided with a hand lever 50 by means of which the shaft 48 may be rotated. A nut 52 is welded or otherwise secured to the jaw member 42 in axial alignment with the opening 46 extending therethrough, and a collar 54 is clamped on the shaft 48 adjacent the jaw member 44 so that as the rod or shaft 48 is rotated and the threads thereon engage the threads of the nut 52, the jaw! members 42 and 44 may be advanced toward one another.
Carried by and extending upwardly from the cross bar 12 of the platform 14 is a curved post 56 which extends between the jaw members 42 and 44. By reason of the resilient support of the seat and back rails 28 and 30 on the arms 24 of the loops 18, it will be obvious that the seat 38 and back 40 of the chair will move in an arcuate path from an upright sitting position, as illustrated in Figure 3, to a full reclining position, as illustrated in Figure 4, and it is, therefore, obvious that the curvature of the post 56 must coincide with the path of movement of the seat 38 and cross member 36.
In use, it will be evident that the occupant of the chair may, by manipulating the hand lever 50, tighten or loosen the clamp jaws 42 and 44 on the post 56 and when the jaws are loosened, the seat 33 and back 40 may be moved to a selected position between the upright sitting position illustrated in Figure 3 and the full reclining position illustrated in Figure 47 When the selected position has been reached, the occupant may manipulate the hand lever 50 to tighten the clamp jaws 42 and 44 on the post 56 to hold the seat and back in the selected position. The en tire operation, of course, may be conducted by the occupant without necessitating his leaving the chair.
In the preferred form of the invention the chair is provided with conventional arms 58 which may be bolted or otherwise secured to the side members 28-30.
While in the foregoing there has been shown and described the preferred embodiment of this invention, it is to be understood that minor changes in the details of construction, combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed.
What is claimed is:
1. A chair comprising a platform adapted to rest on a supporting surface, resilient loops carried by the platform and extending upwardly from the front adjacent opposite sides thereof, arms carried by the loops and extending rearwardly therefrom above opposite sides of the platform, a seat mounted on the arms for movement in an arcuate path above the platform from an upright sitting position to an inclined reclining position, a curved post carried by the platform and extending upwardly therefrom beneath the seat, and a clamp carried by the seat and engaging the post for holding the seat in a selected position in its arcuate path.
2. A chair comprising a platform adapted to rest on a supporting surface, resilient loops carried by the platform and extending upwardly from the front adjacent opposite sides thereof, arms carried by the loops and extending rearwardly therefrom above opposite sides of the platform, a seat mounted on the arms for movement in an arcuate path above the platform from an upright sitting position to an inclined reclining position, a curved post carried by the platform and extending upwardly therefrom beneath the seat, a clamp carried by the seat and engaging the post for holding the seat in a selected position in its arcuate path, and a handle carried by the seat adjacent one side thereof and operatively connected to the clamp for engaging or disengaging the clamp with the post whereby the occupant of the chair may release the clamp, move the seat to a selected position and tighten the clamp while remaining in the seat.
3. In a chair a pair of spaced parallel side bars, a cross bar carried by the side bars and extending therebetween to define therewith a platform, extensions carried by the side bars and extending downwardly therefrom adjacent the rear of the platform to define feet, resilient loops carried by the side bars and extending downwardly therefrom adjacent the front of the platform to define feet which cooperate with the extensions in holding the platform spaced from a supporting surface, said loops continuing upwardly adjacent the front of the platform to define resilient supporting legs, arms carried by the legs and extending rearwardly therefrom above opposite side bars, a unitary seat and back carried by the arms for movement above the platform in an arcuate path from an upright sitting position to an inclined reclining position, a curved post carried by the cross bar and extending upwardly therefrom beneath the seat of the unitary seat and back, the curvature of the post coinciding with the curvature of the arcuate path, a cross bar carried by the 15 seat and extending thereacross adjacent the underside thereof, clamp jaws carried by the cross bar and embracing the post, and a handle carried by the seat adjacent one side thereof and operatively connected to the clamp jaws for tightening or loosening them whereby the occupant of the seat may select a position within the arcuate path and clamp the seat in the position selected.
