2 Claims. (Cl. 155'1`33) This invention relates to new and useful improvements in portable seats.

More particularly, the present invention proposes the construction of an improvedl portable seat which can be used at sporting and other events to convert a bench, bleacher or other backless support into a comfortable chair-like seat.

Still further, the presentA invention proposes forming the portable seat so that it can be easily folded up into compact, lightweight carrying form and secured in `such form for carrying about.

As a further object, the present invention proposes constructing the portable seat with a sturdy, rigid back support and a large, soft sitting portion to provide a maximum of comfort to the user.-

Another object of the present invention proposes constructing t-he seat with a removable cover which can be easily cleaned or washed and on which can be provided convenient carrying and infant-holding straps so as to use the seat both as a sport or spectator seat and an infants safetyV seat.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are' more particularly" setV forth.

In the accompanying drawings` forming a material` part of this disclosure:

Pig. l is a perspective view of a backl'ess bench having clamped thereon three portable seats constructed' and arranged in accordance with the present invention.

Fig. 2 is an enlarged end view of the struc-ture down in Fig. l..

Fig. 3 is a sectional view taken on line 3 3 of Fig. 1.

Fig. 4 is a rear view of one of the seats shown in Fig. i with part-s broken away and in section and with the hanging position shown in dot-dash outline.

Fig. 5 is a perspective View of one of the resilient pads of the seat, parts being shown broken away.

Fig. 6 is a perspective view of the rigid frame of the seat. t

Fig. 7 is a view similar to Fig. 2 but showing a folding ieg base member in addition and illustrating a modification of the invention.

Fig. 8 is a bottom plan view of the structure shown in Fig. 7.

Fig. 9 is a sectional view taken on line 9-9 of Fig. 8.

The portable seat, in accordance with the iirst form of the present invention illustrated in Figs. 1 to 6, inclusive, has a rigid, ilat frame preferably of aluminum or other light metal or alloy and a cover 16 of exible material such as fabric or thermoplastic sheeting.

Frame 15 is U-shaped wit-h two spaced upright members 17 and 18 having a cross member 19 joining them together at one end. The cross member 19 may be formed integral with the upright members or may be secured by screws 20 at Ithe upper end of the frame to the upper ends of the upright members 17 and 18.

2,792,875 Patented May 21, 1957 Clamps 21 and 22, or other securing means are provided at `the free ends of the U-shaped frame 15 on the upright members 17 and 18, respectively, removably to secure the frame rigidly to a` bench 23 or other backless support. Clamps 21 and 22 are G-clamps with spaced arms 24 and 25 adapted to iit over a bench 23 or other backless support. Wing nut screws 26 extend through threaded openings 27 in the lower arms 24 of Ithe C- clamps 21 and 22 rigidly to hold the frame 15 to the bench. The at frame 15 has a front face or surface 28 and thev C- clamps 21 and 22 extend from the front face or surface 27 of the frame at the lower ends of the upright members 17 and 18.

Cover 16 is generally tubular in construction with closed ends 29 and 30 and having a central hinge portion 31 and two end portions 32 and 33. End portion 32 has a` pad-holding pocket 34 with a mouth or pocket opening 35 adjacent the hinge portion and in the rear side 36 of the cover. The hinge portion 31 is in the front side 37 of Vthe cover 16.

End portion 33 of cover 16V has a pad-holding pocket 38 withl a mouth or pocket opening 39 adjacent the hinge portion 31 and in the rear side 36 of the cover 16. The two pocket openings 35 and 39 are opposed when the cover end` porftions 32 and 33 are hanging in alignment as indicated in dot-dash outline in Fig. 4. The pocket openings 35 and 39 are provided by a central opening in the rear side 36 of the tubular cover 16.

End portion 32 of cover' 16 is the back forming half and is adapted removably and frictionally to iit over the frame' 15 covering the cross member 19 and' substantially allA of the upright members 17 and 18 except the clamps 21 and 22.

A resilient pad 40,` preferably of foam rubber, is provided for the pocket 34 of the end portion 32 of cover I6. Pad 40 is shaped as shown in Fig. 6 removably and frictionally to t snug inside the pocket 34 and not to fall' out. Pad 40v lits'v over the frame on the fron-t face thereof so as to provide a completely cushioned back rest.

A similar resilient pad 41 is provided for pocket 38 of end portion 33 of cover 16 snugly to it inside the pocket andtill itout to form a thickly padded seat cushion;

Secured` tof the upper end 29 of the cover 16'i`s a carryinglstrap 42 havingfi'ts endsl attached to ri`ngs'` 43 fixed to the! cover Spaced snap fastener elements 44 are secured to the upper end portion 32 of cover 16 and spaced coacting snap fasteners 45, or other well-known fastener elements, are secured to the lower or seat cushion portion 33 of cover 16 at the end 30 of the cover to hold the two end portions 32 and 33 of the cover together when the cover is folded about its central hinge portion 31 (see Fig. l).

An -adjustable body strap 46 may be provided on the cover 16 and disposed on the upper end portion 32 between the end 29 and central hinge portion 31 of the cover. The body strap 46 may have its ends secured to rings 47 fixed to the cover and may have a buckle 48 for adjustment. The strap 46 will make the seat a safety seat for children or for other safety strap uses.

The modiiication of the present invention illustrated in Figs. 7, 8 and 9 is characterized by the provision of a portable seat having a ilat, rigid frame 50, a ilexible cover 51, back and seat pads or cushions 52 and 53, respectively, and a folding, collapsible base member 54.

Frame 50 has spaced upright members 55 with a cross member 56 at the upper ends thereof connecting them. The lower ends 57 of upright members 55 are connected by hinges 58 to the upper end 59 of a C-clamp 60. The clamp 60 may be a continuation of the upright members, these members being hinged adjacent to and spaced from the hinges.

The clamp 60 has an upper arm 61 which forms the ICC tached collapsible and folding legs 62, V63, 64 and 65 with braces 66, 67, 68 and 69 respectively, to hold the legs in extended position. The `lower arms 70 of clamp 60`contain wing nut headed screws'71 extending through threaded openings 72 so that the seat may be used on a bench or other backless structure if desired lin place of using the legs 62, 63, 64 and 65. y

Hinges 58 permit the back half of the seat to fold forward upon the front half. Snap fastener elements 66 and 67, or other well-known fastener elements, are secured to the upper end 68 and lower end 69 of the cover 51.

A carrying strap 73 is also secured to the upper end 68 of the cover 51. The cover 51 is provided with a pad-holding pocket -74 in its upper end portion`75 and a pad-holding pocket 76 in its lower end portion 77. The pockets 74 and 76 have opposed openings 78 'and 79 adjacent the hinge portion 80 of the cover. In this manner, a portable seat is provided which can be used on any backless bench or other backless support, or can be used independently.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and the right is reserved to all changes and modifications coming within the scope of the invention as defined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent is:
