CHAIR Filed Nov. 5, 1938 Patented Oct. 1, 1940 W tudinally" collapsed when in Vfolded position, "thereby providing a constructionrequirng less storage `space than the ordinary folding chair, and furthermore providing a chair whichjwhen folded and longitudinally collapsed may be convenientlyhandled and carried, and which, if

desired,"may be carri-ed in a holder `or caseof a length materially less than that which would be requiredforthe ordinary collapsible chair when folded.

`It is an object of this invention to provide a" combination folding and collapsing chair of simplified and inexpensive construction, 'which from an `erected `position may be conveniently and Arapidly folded and then longitudinally col` lapsed;` `k

It is also an object of this invention to' provide a chair of the folding type, which when notinv use .can be conveniently folded, after which the seat I"and back are slidably lowered with respect to the legs to afford a compact construction.

" It" isa further object of' this invention to providea chair of the folding type having the seat and back hingedly connected together to contact one another when the `chair is in folded position,`

allowingboth the seat and back to be slidably moved with respect to the chair legs to reduce the normal folded height or over-al1 length of the chair when not in use. a

It is furthermore an object of this' invention to provide a combination folding and collapsible chair wherein both the seat and back have sepa` rate sliding intertting relationship with a pair of the chair legs, allowing the chair when folded tohave the seat and back moved into contact with one another and slidably lowered with respect to the chair legs.

It is an important object of this invention to provide an improved type of combination folding and collapsible chair of inexpensive and simple construction having pivotally connected short and long legs, said long legs having shiftably engaged therewith hingedly connected seat and back members whereby the chair when folded t may have the height or length thereof reduced by slidably shifting the seat and back with respect to the length of the chair.

Other and further important objects of this invention will be apparent from the disclosures in the specication and the accompanying drawing.

`Figure 6 is an enlarged fragmentary detail section taken on the line VI`VI ofV Figure 4; l

As shown inthe drawing: l l l `The improved combination folding and col--y lapsing chair comprises a pair of long or main` legs I which are connected attheir lowerends by means of a transverse frontrung or round 2L Also connecting the two main legs I, inter` mediate the ends thereof, is a transverse supporting bar or cross strip 3 which connects and t braces l the intermediate portions of the two main legs I. l The inner side of each of the main legs I is provided with an upper orchair back guide groove 4 and 'with a lower or chair seat guide groove 5, as clearly illustrated in Figure 2. Pivotally connected to each of the main or long legs I, on the outer sides thereof, `is an auxiliary or shorterv leg 5, by means of a pivot bolt I or the like. The lower ends of the two auxiliary or shorter legs 6 are connected by means of a rear brace rung or round 8. The upper `ends of the two 'shorter legs 6 are connected by a brace or tie rod 9, which when the chair is in extended or open position for use, serves as a front support for the chair seat.

Associated with the long legs I is a chair back I and a chair seat II. The chair back Ill is provided with an arched lower opening I2. Rigidly engaged in the opposite side edges of the chair back IIJ are pivot and guide pins I3, the projecting ends of which project into the upper guide grooves 4 provided in the long legs I of the chair. As clearly illustrated in Figure 2, the lower margin of the chair back I0 is hingedly or pivotally connected to the rear margin vof the chair seat II by means of hinges I4. Rigidly UNITED STATES rATENToFI-ICEV ISIS secured to the side margins of the chair seat II and projecting outwardly therefrom are opposltely positioned guide pins or pintles I5, the ends of which project into the lower guide grooves 5 provided on the inner sides of the long legs I of the chair.

Secured to the bottom of the chair seat II, near the front end thereof, are two hook brackets I6 adapted, when the chair is opened up as illustrated in Figures 1 and 2, to releasably hook or engage over the front brace rod 9 connecting the upper ends of the shorter or auxiliary legs 6 of the chair. When the chair is folded and ready to be collapsed, as illustrated in full lines in Figure 4, the hook members I6 engage over the cross bar 3 connecting the long or main chair legs I. When the chair is opened or setup for use, as illustrated in Figures 1 and 2, the respective sets of legs I and 6 cross one another, with the main legs I projecting downwardly and forwardlygwhile the auxiliary legs 6 project from the bottom of the seat II downwardly and rearwardly. When the chair is opened-up for use, the hook brackets I 6, as the seat drops into position,engage over the brace rod 9, thereby affording a means for limiting the spread of the cross chair legs,'assisted by the guide pins I3 of the chair back I-Il,as said guide pins reach the upper end of the guide groove 4.

if With the chair in open position, the rear portion of the seat II rests upon the cross brace 3r connecting the legs I, thereby providing a double support for the seat II. When the chair is not needed, the same may be readily folded and then collapsed into a compact form, requiring very little space for storage. To collapse the chair, it is only necessary toswing the lower end of the back forwardly and at the same time swing the seat II upwardly into contact with the back I, as shown in dotted lines in Figure 4, after which the seat and back by their own weight are adapted to slide downwardly between the main legs I until the guide pins or pintles I5 of the chair seat reach the lower ends of the guide slots 5, in which position the hook brackets I6 on the bottom of the `chair seat II engage over the brace bar 3. VIt will thus be noted that the chair is first folded and then collapsed to shorten the assemblage byzpermitting the folded seat and back to be dropped from the uppermost position thereof, illustrated in dotted lines in Figure 4, downwardly between the legs of the chair to materially shorten the height or over-all length of the combination folding and collapsing chair. As the chair is being folded and collapsed, the auxiliary or short legs 6 of the chair, being released by the brackets I6, pivotally swing, by the action of gravity, into position adjacent the outer surfaces of the main legs I to provide a collapsed structure wherein all of the members of the chair are positioned in substantially the same plane.

It will thus be seen that an improved type of chair is provided adaptable for use as a beach chair, a camp chair, a card table chair and one readily adaptable for many other uses. One of the important features of the chair is the shortening of the over-all length of the chair when in collapsed position, by the dropping of the collapsed seat and back downwardly between the long legs of the chair and after the initial folding operation has been accomplished. The telescoping of the seat and back downwardly between the legs of the chair materially reduces the overall length of the collapsed chair, permitting the chair to be more conveniently handled and adapting it to be conveniently placed in a suitcase, a carton or the like of a size materially smaller than would be required for the reception of the ordinary type of folding chair which, when folded, is materially higher than the height of the chair when in open position.

It will, of course, be understood that many features of construction may be Varied through a-wide range without departing from the principles of this invention, and it is, therefore, not the purpose to limit the patent granted hereon otherwise than is necessitated by the scope of the.

appended claims.
