FOLDING INVALID-CHAIR.

Specificationof Letters Patent.

Patented Dec. 31, 1918.

Application filed January 13, 1917. Serial No. 142,195.

To all whom it may concern:

Be it known that I, MARION A. DOTY, a citizen of the United States, and aresident of Hartwood, Sullivan county, State of New York, have invented certain new and use,- ful Improvements in Folding Invalid- Chairs, of which the following is a specification accompanied by drawings.

This invention relates to folding or collapsible invalid chairs of the type adapted to be carried from place to place in traveling. The objects of the invention are to simplify and lighten the construction of such chairs, while at the same time producing a wheeled chair in which all parts are foldable upon the body or seat. According to my improved construction, the parts of the chair, including the arms, back, push bar or hand rail, rear wheel standard, foot-rest, main axle and side wheels, may all be folded quickly and conveniently into as small. compass as possible, ready for transportation.

Preferably the arms, back and push bar are foldable upon the top of the seat, while the remaining parts are foldable beneaththe seat. The side wheels are so connected to the axle that they are foldable or collapsible inwardly beneath the seat and lie when folded in a general direction substantially parallel to the seat, so that the folded or collapsed chair forms a substantially flat package and thus occupies the minimum of space, and is of convenient form for transportation in an automobile for instance.

Further objects of the invention will hereinafter appear, and to all these ends, the invention consists of the combinations of elements and features of construction substantially as hereinafter described and claimed.

In the drawings, which illustrate the preferred form of the invention,

Figure 1 is a side view of the chair;

Fig. 2 is a front view of the chair;

Fig. 3 is an enlarged detail perspective view partly broken away of a portion of the post for the rear wheel, showing certain adjustments;

Fig. at is a side view of the chair folded;

Fig. 5 is an end view of the chair folded; Fig. 6 is an enlarged detail side elevation, partly broken away, showing the foldable connections for the axle;

Fig. 7 is a bottom plan view of a portion of Fig. 6;

Fig. 8 is a detail front elevation of a portion of the foldable axle;

Fig. 9 is a bottom plan view of Fig. 8, with the portions of the axle in alinement, and

Fig. 10 is a detail view partly broken away i with the axle folded beneath the seat of the chair.

Referring to the drawings, A represents the body of the chair having the seat B, which may be of wicker or other suitable material. The back C is suitably hinged to the body A by the hinges D, and the sides or arms 0 are hinged to the body by the hinges E and adaptedto be connected to the back by the hooks F when the chair is in use. order to fold the sides and back, the hooks F are released, the sides are folded down on the seat, and the back is folded down over the sides.

The push bar or hand rail G for pushing the chair is provided with the arms H pivoted to the body at J by a pin and slot connection, which affords a slight longitudinal movement of the arms H for releasing and locking them. The ends of the arms H are cut away or recessed at K and notched at L to enable said arms to cooperate with the pins 0 and lugs P on the body when the push bar is in operative position, as shown in Fig.

1, in which case the ends of the arms H engage the pins 0 and the notches L engage the lugs P. By pressing upwardly on the push bar G, at the same time withdrawing the arms H rearwardly, the ends of the arms are released from the pins 0 and lugs P, to permit the push bar G and arms H to be folded downwardly over the body of the chair, as illustrated in Figs. 4 and 5'. When the chair is to be used, the push bar G and arms H are swung into operative position, as shown in Fig. 1, and locked by means of the pins 0 and lugs P.

The small rear wheel Q is conveniently mounted in the fork R carried by the rear standard S, which in turn is suitably pivoted to the body A as by means of the hinge teeth, so that the standard Sand wheel Q may be folded inwardly beneath the body A, as

are provided for maintaining the rear stand ard S inupright position when the chair 1s in operation, and as shown, the upper end S.

illustrated in Figs. 4 and 5.. Suitable means l of the standard bears against a,bufi'er plate ,10 bask/or ghee-y portion a of the foot, restis The foot-rest, as shown, consists of back portion wand the foot ortion ,6 hinged to the back portion a as by means of a hinge c.

The push bar G and arms H connected thereto are thus swung into position about the pivot pins J and the ends of the arms H are locked on the pins 0 and lugs P, and the chair is then ready for use. As heretofore described, in collapsing or folding the chair, the parts are folded in reverse direction, that is, first the sides or arms C and back C are folded, then the push bars G and arms H, so that the parts on top of the seat are first folded. It will then be convenient to let the chair rest on the push bar G, while the rear standard S is folded inwardly, and the axle r is collapsed. Then the foot rest is folded inwardly and the side wheels are folded in upon the back rest.

I am not to be understood as limiting the invention to the details of mechanical construction shown and described, since obviously mechanical equivalents may be found for many of such parts, which will come within the scope of the claims.

I claim and desire to obtain by Letters Patent the following:

1. In a folding chair, the combination with the body, of an axle having jointed end sections forming bearings for the side wheels, standards pivoted to the body and slidably connected to the axle, aflording provision for folding or collapsing the axle toward the body, a standard for the rear wheel pivoted to the body and foldable beneath the body, the side wheels also being foldable upon the body over the rear standard and wheel.

2. In a folding chair, the combination with the body, of an axle having jointed end sections forming bearings for the side wheels, standards pivoted to the body and slidably connected to the axle, affording provision for folding or collapsing the axle toward the body, a standard for the rear wheel pivoted to the body and foldable beneath the body, and a foot-rest pivoted to the body and foldable over the axle and rear wheel, the side wheels also being foldable upon the body over the foot-rest and rear wheel.

3. In a folding chair, the combination with the body forming a seat, of sides, back and push bar pivoted thereto and foldable upon the top of the seat, a rear wheel standard and a foot-rest pivoted to the body and foldable beneath the seat, an axle adapted to be collapsed or folded beneath the seat, and main side wheels also foldable underneath the seat over the rear standard, axle and foot-rest.

4:. In a folding chair, the combination with the body, of an axle having jointed end sections forming bearings for the side wheels, standards pivotally supported beneath the body and arranged to fold inwardly, sleeves sliding on the axle and pivotally supported at the outer ends of said standards and latches carried by the sleeves for locking the sleeves to the axle when the sleeves are over the joints of the axle.

5. I11 a folding chair, the combination with the body, of an axle having jointed end sections forming bearings for the side wheels, standards pivotally supported beneath the body and arranged to fold inwardly, sleeves sliding on the axle and pivotally supported at the outer ends of said standards and latches carried by the sleeves for locking the sleeves to the axle when the sleeves are over the joints of the axle, said latches also being adapted to lock the sleeves to the axle when the axle is folded or collapsed against the body.

6. In a folding chair, the combination with the body, of an axle having jointed end sections forming bearings for the side wheels, standards pivotally supported beneath the body and arranged to fold inwardly, sleeves sliding on the axle and pivotally supported at the outer ends of said standards, and latches carried by the sleeves for locking the sleeves to the axle when the sleeves are over the joints of the axle, said latches also being adapted to lock the sleeves to the axle when the axle is folded or collapsed against the body, the joints of the axle affording means for folding the wheels inwardly toward the axle and body when the sleeves are moved toward the middle portion of the axle.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
