Flanders, Detroit, Mich. Application December 23, 1935, Serial No. 55,692 1 Claim. (Cl. 155-133) This invention relates to portable seats, and hooks I! should be large enough to permit the has particular reference to a collapsible chair adapted to be used at sporting events, at the engagement of various thickness of material to render the device universally applicable to all beach, and on other occasions. “bleacher seats" and the like. The rear ends of the base members III are drilled to accommodate the rivets I! which secure the members III to An object of the invention is the provision of a device which may be used in cooperation with ordinary “bleaoher seats" to form a comfortable seat and to support the user's back. - Another object of the invention is the provision. 10 of a device of the character referred to which is easily collapsible and foldable into a compact and lightweight bundle which may be readily car ried about. ' Still another object of the invention is the pro 15 vision of a device which may be adapted to be used upon the ground or at the beach to form a comfortable seat. A further object of the invention is the provi sion of a device which will protect the user's 20 clothes from becoming soiled by sitting upon dirty "bleacher seats” or upon the ground. ‘ Other objects and advantages of the invention will appear as the description proceeds. The invention resides in the improved construc tion of the portable seat, and in the combination and arrangement of‘parts, the novelty oi.‘ which will be particularly pointed out and distinctly ‘claimed hereinafter. In the accompanying drawing, which consti 30 tutes part of my disclosure, I have fully and clear ly illustrated a preferred embodiment of the in vention, in which drawing: Fig. 1 is a perspective view of my portable seat being used in conjunction with an ordinary 35 “bleacher seat”; and Fig. 2 is a side elevation of the device shown in Fig. 1, but adjusted to be used on the beach or upon the ground. Referring now more particularly to the draw 40 ing, it will be seen that in the embodiment here in disclosed, my device is extremely simple in con struction and comprises the base members iii, the side members H and the supporting arms ii. For the sake of strength and compactness, I pre 45 fer to construct the members i0, II, and H of short tubular pieces, which may be chrome or otherwise suitably plated to present an attractive appearance. However, the above mentioned the side members II. This construction permits the rivets I! to act as pivots to enable the mem bers l0 and H to be folded together. Intermedi ate the ends of the base members iii are posi tioned the loops l6 which are adjustably secured in place by means of rivets iGa which pass through holes in the members I ii. The aforesaid loops l6 are arranged to engage the hook-shaped lower ends I‘! of the supporting 15 members l2 to hold the side members ii in the proper relative position with the base members ill to form a comfortable seat. The loops [6 are made large enough to permit the insertion of the hooks i1 therethrough. The upper ends IQ of the 20 supporting arms II are pivotally secured to the side members H by means of the rivets 19 to en able them to'v be folded compactly together for carrying purposes. Lateral support for the portable seat is pro 25 vided by the two horizontal bars 20 and 2| which are pivotally secured at their outer ends to the upper extremities of the side members II by the rivets 2,2. The inner ends of the bars 20 and 2| are connected by means of the hinge 23 which 30 allows them to fold downwardly to enable the entire seat to be packed into a compact bundle. To prevent the seat from collapsing when in use, the bars 20 and 2| are fastened together by any suitable attachment such as the hook 24 and the 35 eye 25. ' The back and the bottom of the portable seat are covered by the fabric pieces 26 and 2'! respec tively, which may be made of any satisfactory material and which are sewed or otherwise suit 40 ably secured to the side members II and to the base members Hi. The fabric piece 26, which forms the back rest of the seat, is out with the two upper strips 28 which are sewed around the horizontal bars 20 and 2|. The loops thus formed 45 around the aforesaid bars are free to move along the bars to prevent binding and tearing of the material when the seat is folded. The fabric members may be made of any suitable material . piece 2'! which forms the base of the seat is cut 50 as at 29- (Fig. 1) to permit unobstructed opera and also in other shapes. The base members l0 are bent downwardly tion of the thigh n and the rings Is. An advantageous feature of my invention re and rearwardly at their front ends to form the hook-like extensions ii, the latter being adapted to engage the front edge of the bleacher seat ll 55 (Fig. 1) to hold the'portable seat in place. The sides in the eise with which the portable seat may be adaphted‘?' serve either as an auxiliary bleach er seat‘onas a ground or beach seat. The lat 55 ter adaptation is shown in elevation in Fla. 2 and hereinafter described.

By varyins the position of the arms II, the back oi! the seat may be adjusted to any desired inclination to suit the individual user. when beina used on the beach or on sandy or soft soil, the hook-shaped forward ends ll 01' the base members ll may be pressed into the around 3| as shown in Fla. 2 and serves as an chors. Likewise the lower ends I‘! of the arms 15 I! should be pushed into the around 30 to hold them in place. _ As a around seat my device has numerous valu able advantages, includina comfort, cleanliness, protection from the damp around and many 20 others. The ease with which my portable seat may be set up, and taken down and folded toaether, ren der it invaluable to spectators at outdoor events. when folded, the seat occupies a minimum of space and may be easily carried about from place to place. To told the seat, the user need only unfasten the attachment 2! and told the bars 2. and II downward and toaether.

Althouah I have herein disclosed a certain em 10 bodiment of the invention, it will be understood that various modi?cations may be employed, without violatina the spirit of the invention, all oi which are intended to be within the scope of the appended claim. Having described my invention. what I claim and desire to secure by Letters Patent is: In a leaiess seat includina a back rest and a seat portion pivoted to each other. the combina tion 01' side arms pivoted at one end to the side 20 members of said back rest and provided at the other end with hooks adapted to enaaae means comprisina bails pivoted to said seat portion, and a cross member 0! hinaed sections pivoted at either end to said side members. said hinaed sec- 25 tions havina means to lock them in horizontal v alianment.
