NNNNNN OR LOUIS P. aaaaa Z Patented Nov. 7, 1944 UNITED STAT ES PATENT oFFl CE- GHAIROART I Ennis P. Brantz, Philadelphia, Pa.

ApplicationAugust 5, 1943,. Serial:No.- 497,516 4 Claims. (or 280936) This invention relates toxfolding' chair carts, also known as folding strollers,- and has as:- its object the production of: anew and improved de-- vice of this type.

More particularly stated, it'is one of the ob jects of my invention to simplify thev latching. means for holding folding chair carts in the operative position.

It is/a further objectof thisvinvention totsim plify the latching structure: of the back restof. folding chair carts, v t

It is: as still further object of my invention to produce a folding chair cart which will be comslatsa to which serve both as bracers for. thebase frame- 2- and as supports for any packageswhich paratively simple in structure and comparatively easy to manufacture,

For the purpose of illustrating my inventionwith the particularity requiredfbylaw, I have. shown in the drawings. whichform. a .part hereof and will now describe: one of the many possible physical embodiments of my inventive con cepts.

In said drawings,

Figure 1 is a, perspective view of my. novel chair cart in its unfolded or operative positiom A portion of 'one of the rear wheels has been brokenaway to show otherwise hidden parts. The adjustable back rest is shownin a horizontalposition for the purpose ofcl'ear-ness. I

' Figure 2. is a perspective view of my novel chair cart in its? operative position with the back rest. in the innermost of its upright or operative p0. s iti'ons'.

Figure 3 is a' perspective view of my novel chair cart in its folded position.

Figure 4 is a section along theline 4-4 of' Figure 1. V

Figure 5' is a section along the line 5-5 of Figure 2.

Figure 6- is a section along the line 6--6 of FigureZ.

Figure '7 is a section along the line 1-4" of Figure 1.

Referring more particularly to the drawings wherein similarreference numerals denote similar' parts, reference numeral l designates my novel chair cart as a unit.

The chair cart I consists of a base frame 2' supported on wheels t5, a vertical frame 3 carried by said base frame, a seat 4 supported by said vertical frame 3, a back rest 5 pivoted along one of its edges in said seat 4, and a cross handle 6 carried by said vertical frame 3.

The base frame 2 consists of two spaced apart bars I, two spaced apart axles 8 attached to said bars I, a foot rest 9 carried by said bars I, and

the pusher of the chair cart may desire to havethe chair cart carry;

The vertical frame 3. consists of two spaced: front columns I 2, two-spaced rear columns I 3, andrtwo-armrests. l4.. The-upper end of each of. the front columns: 12: is pivotally connected to. that arm. rest Illv which. is. contiguous thereto as shown at 1.6:, andthelower end of eachof' said front columns I2 is pivotally connected to the bar 7 which isicontiguous thereto, as shown at 11. Similarly the upper end of. each of. the. rear columns i3. is. pivotally connected to the arm rest. M which is contiguous thereto,; as shown. at 36), andv the lower endv of each of said rear columns I3. is pivotally connected to the bar T which is contiguous thereto, as shown at 31; The front columns I2 have attached thereto near the lower ends thereof the sl'at 3 and the rear columns I31 have attached thereto near the lower ends thereof the slat 351 The slats 34 and. 35 serve as stop members for the packages which are placed on the slats I01 "said handle.

The seat 41 is pivotally attached at its front end to each of the-front columns 12;.as shown at 20, and at its rear enditc each of "the rear. c'olumns 13,, as'showni at 21.

The back rest 5' consists of a body member" having the. sides 22. each of which is pivotally attached at its lower end to the seat 4, as shown at 38,, a' channel forming" arm 2'3 U shaped: in cross-section attached to' each of said sides 22 with the U facing'inwardlythereby formingtwo' spaced apart slots 24 on said'b'a'ck rest 5", and a. backrest latching bar 25 slidablymounted in said slots 24". The back restlatching bar 25 terminates' at each of its'endsin a pin 26 each of which is'received in suitable notches 19" formed" in the arm rest M which is contiguous thereto to hold saidback rest 5*in anyone of a numberof ver tical positions.

The cross-handle 6" consists ofa handle 28and two spaced apart arms 2? which are attached to As=shown at I8, each of said arms" 2"! is'pivotally attached at a point intermediate its ends toithe' arm rest M which is contiguous thereto. Each of said arms has formed therein near the lower end thereof a plurality of positioning apertures 29 which are adapted to register with similar apertures l l formed in the bars 1. The registering apertures H and 29 receive the fly bolt 30 which clamps said arm 21 to said bar 1 thereby latching the chair cart in its operative position.

3! and at its other end in a threaded portion which receives the fly nut 33.

It is clear from the foregoing description that the latching bar 25 combines with the notches If! to form a structure whereby the back rest may be readily latched in any one of a plurality of positions. The number of these positions is determined by the number of notches.

It is also clear from the foregoing description that the apertures H in the bar I of the base frame 2, the apertures 29 in the arms 2'! of the cross-handle 6, and the fly bolt 30 combine to latch the chair cart in any one of a plurality of desired positions. The number of these positions is determined by the number of apertures 29 and H.

It is also clear from the foregoing description that since each of the arms 27 of the cross-handle 6 is continuous, the structure which latches the chair cart in its operative position is not only simple but it has the additional advantage of making it impossible for the chair cart to buckle and collapse once it has been latched in the operative position.

Having described my invention what I claim as new and useful'is:

1. A chair cart comprising a base frame comprising a pair of spaced bars, each having a plurality of anchoring aperturesformed th'erein, attached to a pair of spaced apart axles which are supported on wheels; a pair of spaced apart columns pivotally attached to each of said base frame bars near the respective ends of each of said columns; a seat pivotally attached to each of said columns intermediate the respective ends of said columns; two arm rests, each pivotally attached to one of said pairs of columns, each terminating in a portion which extends beyond the point of attachment to one of said columns and which has formed therein a plurality of latching pin receiving notches; aback rest pivotally attached near its lower ends to said seat; a slot formed in said back rest; a latching bar, terminating at each of its ends in a latching pin each positioned for being received in any one of said arm rest latching pin receiving notches of the arm rest which is contiguous thereto, mounted for horizontal movement in said back rest slot; a cross handle consisting of a handle portion and a pair of spaced continuous arms each attached to said handle portion and each pivotally attached to one of said arm rests at a point intermediate their respective ends, each of said cross handle arms having formed therein near the lower end thereof a plurality of anchoring apertures positioned for registry with the anchoring apertures formed in said base frame bars; and means extending through said anchoring apertures when in registry for detachably'attaching each of said cross handle arms to one of said base frame bars.
