Specification of Letters Patent.
Patented June 1, 1920.
Application filed December 9, 1919. Serial 110. 343,632.
To all whom it may concern:
Be it known that I, OUTHBERT HORNER lVALMsLEY, a subject of the King of Great Britain, residing at Clarendon House, Eccles, Lancashire, England, have invented certain new and useful Improvements in Collapsible Chairs; and I do hereby declare that the following is a full, clear, and exact description of the same.
This invention relates to collapsible chairs of the type including rigid collapsible frame-work and a flexible seat, 6. 9., a seat composed of canvas, and has for its object to provide an improved construction of chair of this type.
To this end, the invention consists broadly in a collapsible chair comprising a collapsible tripod structure the base of which is intended to rest on a supporting surface and one limb of which is extended upwardly to form a backsupport for a flexible seat and a preferably isosceles triangular structure foldable on the tripod structure, the apex of the triangular structure being pivotally connected to the extended limb and the base of the triangular structure being wholly detachable and being embraced by the forward end of the flexible seat, the entire structure being conveniently separable to form a bundle capable of being enwrapped by the flexible seating.
The invention is illustrated in the accompanying drawing in which Figure 1 is a side elevation, Fig. 2 a front elevation, Figs. 3 and 4 fragmentary views showing the junction of the limbs of the tripod and Figs. 5 and 6 are fragmentary views showing the junction of sides of the triangularstructure with the extended limb.
As shown, the improved collapsible chair comprises a tripod structure 1, 2, 3, the base of which is intended to rest on a supporting surface 6. 9., the ground and one limb 1 of which is extended upwardly to form a back support for flexible seat .1 e. 9., a seat composed of canvas, the seat being preferably mounted on a rod 5 provided with a loop 6 for engagement with one of a series of notches 7 provided for adjustment of the seat to vary the sitting posture of an occupant.
Hingedly connected to the member 1, are the sides of a triangular structure 9, 10, 11, the member 11 being enwrapped by the forward marginal edge of the seat and being conveniently separable from the sides 9, 10, so that the sheet constituting the seat 4: may be employed as a wrapper for the framework when collapsed and bundled together.
The members 9, 10, are hingedly connected at 8 to the member 1 and are mounted on a pivot 13 penetrating the memberl so that such members 9, 10, may fold into substantial coincidence with the member 1.
The members 2, 3, which are pivoted to the members 9 and 10 as at 16, are separable from the member 1 and are provided with studs 14; engaging pockets in such member 1, a tension element 15, e. g a chain being provided to resist any tendency for the members 2, 3, to spread.
It will be readily seen that, when the chair is to be collapsed, and parceled, it is merely requisite to disengage the loop 6 from a slot 7 disengage the member 11 from the members 9, 10, and fold the members 9, 10 into the closed position against the member 1, disengage the members 2, 3 from the member 1, bundle all the members together, and wrap the bundle in the sheet constituting the seat.
What I claim is A collapsible chair comprising three legs articulated to one another, and constituting a tripod, the central. leg formed with an up- 'ward extension, a collapsible isosceles triangular structure jointed at the apex to said central leg, its equal sides being jointed to the two remaining legs of said tripod, and
a roll-up seat bridging said extension and the base of said triangular structure, said legs and the members of said triangular structure being readily separable and capable of assembly to a bundle to be enwrapped in said seat.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
CUTHBERT HORNER WALMSLEY.
