. 4 Claims.

This'invention relates tofolding seats which can be carried as a cane, and it has among its salient objects to provide a folding seat having a tubular body with seat-supporting arms pivotally connected in the upper end thereof and foldable together above said body, and having spreading legs or feet members, pivotally connected in the lower end of said body, and foldable together below said body and in alinement therewith, said seat supporting arms and said leg members being operatively connected together through said tubular body, whereby the operation of one antomatically operates the other from opened to closed positions and vice versa; to provide in such a folding seat, improved mechanical hinge connections between the seat-supporting arms and the feet or leg members, whereby there is free and, easy movement of said parts, both in opening up said seat for use as such, or in closing it to folded condition, to be carried by its seat arms much as a cane is carried.

In order to explain my invention, I have illustrated one practical embodiment thereof on the accompanying two sheets of drawings, and in which:

Figure 1 is a side view of a folding seat embodying my invention, in'folded condition, with a part of the tubular body broken away to show the interior connections;

Figure 2 is an edge view, as seen in section, taken on the line 22 of Fig. 1;

Figures 3, 4, 5 and 6 are cross sectional views taken on the corresponding cross sectional lines on Fig. 2; but showing full cross sectional views;

Figure 7 is a sectional detail on line I--'I of Fig. 5;

Figure 8 is a longitudinal sectional view through the body, feet and arms, showing the seat in open condition, the middle portion being broken out to shorten the figure; and

Figure 9 is a plan view looking down on the open seat, as seen in Fig. 8.

Referring now in detail to the drawings, my invention as here shown for descriptive purposes includes a tubular body I0, which can be of any attractive and suitable material, as metal or plastic.

The upper end of said tubular body, at opposite sides, has two extensions or wings, as l I, I l, with two Y-shaped, seat-supporting members I2, I2, pivotally connected at their lower ends between said extensions or wings II, II, on a pivotal bolt I3, as clearly seen in Figs. 1, 2 and 3.

The connected ends of said seat-supporting members I2, I2, are shown with shoulders I2 formed thereon to rest on the upper opposite edges of the tubular body, when said arms are out in their supporting positions, as seen in Fig. 8.

At the lower end of said tubular body I0, four short legs or feet, as I4, I4, of tapering form and curved in cross section, are pivotally connected at their upper ends, as by means of straight middle web-like extensions, as I5, I5, seen in cross section in Figs. 5 and 6, a pivot split ring as It, serving as the pivot, and which ring is held in place by short screw bolts, as It, I6, and seen in Figs. 2, '7 and 8.

Two interfitting hair-pin like spring members, H, H, have their lower ends twisted and pivotally connected with said web extensions I5, I5, as at I8, I8, with pin and slot connection as shown.

The upper arched ends of said hair-pin members overlap each other, as at IT, and are connected together by means of a bolt I9, threaded through said members H, H, and into a block or nut 28, in the inner member H, with a lock nut 2| above said members at H, to more firmly secure them together.

The upper end of said bolt I9, is threaded into a head or block 22, to which is pivotally connected the lower ends of two links, as 23, 23, the upper ends of which links are connected, as at 24, 24, to the lower connected ends of the two Y-shaped seat-supporting members I2, I2, to one side of their hinge pin I3, as clearly shown in Figs. 2 and 8.

An outer ring 25 is placed around the lower end of the tubular body Ill, in position to receive the abutment of the upper shoulders I4, I4 of the legs I4, I4, as they are spread out into supporting positions, and as seen in Fig. 8, forming a bearing therefor and making a more rigid structure than if there were looseness in connection with the upper or anchored ends of said supporting legs.

A seat member 26, which may be of canvas, or other material, is shown, with cut out portions, as 21, 21, at the sides to expose the seat members for a hand grip, as will be clear from Fig. 1.

In the tubular body l0, spaced apart longitudinally of said body, are two angle members, as 28, 28, to serve as guides for the connecting bolt I9. The guides hold the parts in good operating positions and give additional strength to the structure.

I do not limit the invention to the details of construction and arrangement shown for ex-- planatory purposes, except as I may be limited by the hereto appended claims forming a part of this application.

I claim:

1. In a folding seat, a tubular body, a pair of Y-form seat-supporting arms pivotally connected together at their lower stem ends in the upper open end of said tubular body, a plurality 5 of short legs of tapering form and curved in cross section with a longitudinally extending web member in the middle of each, said legs being pivotally connected by the; upperends of said web members to the-sides of said tubular body, in the lower end thereof, an abutment ring around the lower end of said body and a shoulder on the outer upper end ,of each legto bear against said abutment ring when said legs;- are in open positions, and adjustable connecting links from the connected ends of said-,asupl-t porting arms, to one side of theirpivot, and to. 1 the pivoted ends of said short legs and to one side of their pivots, whereby said seat suppurtw ing arms and said short pivoted legs are simultaneouslr a e i-t h n-in .z n e u o 01 -1- eratin positions,
