3 claims. (ci. A15s-:133)
The present invention relates to a chair attachment for benches or bleachers and the like.
The primary object of the invention is to prov1de a chair attachment that may be conveniently attached to benches, bleachers, picnic table seats and the like to provide a more comfortable seating arrangement thereon.
A very important object of the invention is to prov1de .a collapsible chair attachment which may be carried much as a suitcase or briefcase and which is enabled to utilize the means for clamping the attachment to a bench or the like as the means for retaining the chair attachment in its collapsed position.
A further object of the invention is the provision of a collapsible chair attachment capable of simple and economical production, of light weight and which is very easy to collapse and set up for use.
These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:
Figure 1 is a perspective View of the chair attachment attached to a bleacher or bench in its open position;
Figure 2 is a perspective View of the attachment in its collapsed position;
Figure 3 is a cross-sectional view of the attachment in its collapsed position, taken substantially along section line 3-3 of Figure 2;
Figure 4 is a perspective view of the clamping means for clamping the attachment to a supporting surface and for locking the attachment in its collapsed position;
Figure 5 is a cross-sectional View of the forward edge of the attachment seat disclosing the disposition of the clamping means for mounting the attachment on a supporting surface, taken substantially along section line 5-5 of Figure l; and
Figure 6 is an enlarged detail view of one edge of the undersurface of the seat with the clamping means being attached thereto.
In the drawings, the attachment is designated in its entirety by the numeral 10 and is seen to comprise a seat member 12 and a back member 14. The lower edge of the back member is hingedly connected to the back edge of the seat member so that the back member 14 will collapse upon the seat member 12 and may be swung outwardly therefrom lto open postion, as shown in Figure l.
Flexible straps 16 extend between the side edges of the seat and back members 12 and 14, respectively, to limit the opening movement of the back member 14. Fasteners 1S secure one end portion of each strap 16 to the side edge of the seat member intermediate the front and back edges thereof, whereas fastener 19 secures the opposite end portion of each strap 16 to a side edge of the back member 14 intermediate the upper and lower edges thereof. The seat and back members 12 and 14, respectively, are of identical size and configuration so that the edges of these members will be coplanar with one another when the attachment is in its collapsed position, as shown in Figures 2 and 3.
The seat member 12 of the chair 10 comprises a rectangular frame 20 of any suitable rigid material, such as wood, having a recessed area 22 on the undersurface thereof. Leather, cloth, plastic or other suitable material 24 is stretched over the frame 20 and folded back Patented Feb. 15, `1955 under the recessed area .22 of the frame. `Suitablesoft wadding or filler 26 is .then .placed within the frame a hard back Vor yundersur'face `32 .has .its edge 1portions seating :in the recessed larea 22 `around 'the undersurfaee of the frame and is suitably tacked or `otherwise.secured thereto. Thus, the soft waddingis yh eld between theseat covering and the seat fbacking .-24 and .32, respectively.
The seat back is of identical construction, Acomprising an open frame 30, covering 34, wadding 56 land lhard back 38. n
To retain the Vseat in its :open post-ion on a-supporting structure land to retain the attachment .in `its collapsed position, ya lclamping rmeans 40 vis provided, the clamping means consisting -of 4'a U-shaped-clamping element :including the bight portion 42 and flanges 44 and 46.
In collapsing the chair, the seat member 12 and the back member 14 are folded into abutment with one another with the flexible strap 16 being folded inwardly to be received between the abutting surfaces of the seat and back members. i
To retain the chair in its collapsed position, the upper edge of the back member 14 is provided with an upwardly projecting turnlock 48 adjacent each corner thereof. The bight portion 42 of each clamping element 40 is provided with a longitudinal slot 50 through which the turnlock 48 extends, turning of the turnlock 48 after extension through the slot 50 clamping the bight portion 42 of the clamp 4i) to the upper edge of the back member. Flanges 46 and 44 of each clamping element 40 straddle the seat and back members 12 and 14 and thereby retain them in their collapsed position. Handle 52 is provided centrally of the upper edge of the back member 14 for carrying the attachment in its collapsed position, much as a briefcase.
The backing member 32 forming the undersurface of the seat member 12 is provided with a pair of longitudinally spaced downwardly depending fastening elements 54 adjacent the forward edge thereof at each corner.
Flange 44 of the clamping element 40 is providedwth a pair of longitudinally spaced L-shaped locking slots 56 opening into one edge thereof. To adapt the chair attachment for its seating position, the clamping elements 40 are removed from their position locking the attachment in collapsed position, and the flange 44 is secured .to the studs or fastening elements 54 by way of the locking slots 56 and the attachment opened to its seating position. Then, the seat member 12 is slipped onto a bench or the like 58, as shown in Figure 1, with the clamping elements 40 having the anges thereof straddling the forward edge portion of the bench to retain the seat thereon.
From the foregoing, the construction and operation of the device will be readily understood and further eX- planation is believed to be unnecessary. However, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the appended claims.
What is claimed as new is as follows:
l.. A chair attachment for benches and the like comprising a seat and a back hingedly connected to one another for swinging movement from a collapsed position abutting one another to an open seating position,
