COLLAPSIBLE CHAIR.

Specification of Letters Patent.

Patented Jan. 2, 1917.

Application filed April 20, 1915. Serial No. 22,694.

To all whom it may concern Be it known that I, TONY Rrzzo, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented new and useful Improvements in Collapsible Chairs, of which the following is a .specification.

This invention relates to collapsible chairs such as are generally known as camp chairs.

The invention has for its object to produce a collapsible chair having a metallic frame of channel construction which while capable of supporting a heavy weight will be light and capable of folding into small comass.

A further object of the invention is to simplify and improve the construction and assemblage of the parts comprising the frame structure of the chair.

A further object of the invention is to improve the construction of the seat and the manner of assembling it with the chair frame. v

With these and other ends in view which will readily appear as the nature of the in vention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claim.

In the accompanying drawingshas been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claim may be resorted to when desired.

In the drawings,-Figure l is a perspective view showing the improved camp chair extended for use. Fig. 2 is a perspective View showing the chair partly collapsed. Fig. 3 is a top plan view. Fig. 4: is a vertical sectional view taken on the line 44 in Fig. 3. Fig. 5 is a horizontal sectional view taken on the line 55 in Fig. 4. Fig. 6 is a perspective view showing the chair folded or collapsed.

Corresponding parts in the several figures are denoted by like characters of reference.

The legs 15 are formed of pieces of channel iron or steel provided at their lower ends with foot pieces 16 and at their upper ends with lugs or cars 17 which are apertured for the passage of pivot members 18 whereby the legs are pivotally connected with the three radial arms 19 of a bracket 20. Arms 21, also formed of channel ironor steel, are provided at their lower ends with ears or lugs 22 which are connected with the legs 15 near the upperends thereof, a short distance below the points at which the legs are pivotally connected with the bracket arms 19. The channel pieces constituting the arms 21 are of a width exceeding that of the channel pieces forming the legs 15, which latter are capable of being received within the channel pieces forming the arms 21. j

The legs 15 are connected with the arms 21 by jointed connecting members C, each of which is composed of two links 24:, 23 pivotally connected'together at one end, as seen at 25, and pivotally connected at their opposite ends, respectively, with a leg 15 and with an arm 21. Each leg is in this manner connected with its mating arm by two connectlng members G disposed adjacent to opposite sides of the said leg and arm so as to be capable of folding adjacent to the outer faces thereof when the joint formed by the pivot 25 is broken. The pivots that connect the lower ends of the links 24 with the legs 15 also serve to pivotally connect with said leg's the outer ends of brace links 27, the inner ends of which are pivotally connected with angle plates 28 that serve to connect the brace links together in such fashion that they will be capable of folding upwardly in the direction of the bracket 20 when the legs are collapsed.

The arm members 21 are provided at their upper ends with hooks 29, one of which has hingedlyconnected therewith a link 30 constituting a lever. The seat 31 which is made of textile or other flexible material is triangular in shape and is provided at each corner thereof with a loop 32 with which a ring 33 is connected. When the frame of the chair is extended for use 1 two of the rings 33 may be engaged with two of the hooks'29, after which the link or lever 30 may be passed through the third ring, which then by manipulating the lever may be drawn over and into engagement with the third hook 29, the lever 30 constituting a lock whereby it will be retained in position. When the chair is extended for use, the legs 15 diverge downwardly and outwardly from the bracket 20, their outward movement being limited by the brace links 27 the inner. ends of which are lowered to the position seen in Fig. 1.

The arms 21 diverge upwardly and out- Wardly with respect to the bracket 20 and are retained in extended-position by means of the flexible seat, With the corners of which the upper ends of the arms are connected. The connecting members C by this 7 time will have become extended to an legs to fold in view of dated in the channels .of the arms 21, the

connecting members C folding adjacent to the outer faces .of the arms. The frame may thus be folded very compactly and, when folded, it maybe Wrapped in vthe flexible seat member, thus forming a ery small,

light and compact package.

The improvedchair Will be found useful for .a great variety of purposes, especially the fact that it may be folded within such small compass that .it maybe carried zinia grip ,orsuit case. When made of proper material, such as a good quality of channel steel, it will be found of greater strength and lighter Weight, as Well as of smaller dimensions thana chair of similar capacity made of -WO0d or like material. Having thus described the What is claimed as new, is

In a collapsible chair, a frame comprising a bracket having radial arms, channeled legs pivotally connected With said arms,

channeled arms pivotally connected with the legs and capable of receivingsaid legs partly ithin their respectlve channels when the chair 1s collapsed, jo nted con- .necting members terminally connected pivotally Withthe respective legs and arms near the free ends thereof and at the outer sides thereof brace links pivotally connectedvwith the legs at -the pivots Which con- .nect ;the jointed .me nbers thereto and capable of being received partly within the channels thereof, and angle ,plates with which said brace links are pivotally connected and adapted ;to be received in the channels of the ,legs When the chair is collapsed.

In testimony whereof I affix mysignature in presence of ,tWo itnesses.
