ALFRED N. FLEURY AND CARL IE. MAYER, OF BRG'OKLYN, IIEW YORK.

FOLDING GOCART.

Application filed April 23, 1921. Serial No. 485,237.

To all whom it may cone-er Be it known that we, Armani) N. FLnUnr and CARL F. MAYER, citizens of the United States, and residents of the city of New York, borough of Brooklyn. in the county of Kings and State of New York, have invented a new and Improved Folding Gocart, of which the following is a full, clear, and exact description.

This invention relates to go-carts or childrens vehicles and has particular reference to a folding or collapsible go-cart.

The invention contemplates for one of its objects the provision of a go-cart, including means which renders the same readily foldable into a small and compact article, whereby the same may be transported in folded condition in railways, automobiles, or other public conveyances.

A further object in view resides in the provision of the novel means for respectively looking or retaining the vehicle in its set-up or folded positions.

The invention further contemplates the provision of a folding go-cart which is compara'tively simple in its construction, inexpensive to manufacture and produce, and in which the means forarranging the same in set-up or folded condition is readily operable by persons unfamiliar with mechanical constructions.

With the above recited and other objects in view, the invention resides in the novel construction, combination and arrangements of parts set forth in the following specification, pointed out in the appended claims and illustrated in the accompanying draw ings, it being understood that the right is reserved to embodiments other than those actually illustrated herein, to the full extent indicated by the general meaning of the terms in which the claims are expressed and by variations in the phraseology of the same.

In the drawings Figure 1 is longitudinal sectional view through the go-cart, illustrating the same in its set-up condition;

Fig. 2 is a detail transverse sectional view taken on the line 22 of Fig. 1.

Fig. 3 is a bottom plan view of the go-cart in. set-up condition.

Fig. 4. is a fragmentary transverse sec tional view taken approximately on the line 44L of Fig. 1, and illustrating respectively in full and. dotted lines the arrangement of parts in set-up and folded condition.

Fig. 5 is a fragmentary longitudinal sec tional view illustrating the means for looking and retaining the go-cart in set-up position, shifted to permit of the folding of the same.

Fig. 6 is a bottom plan view illustrating the go-cart in folded condition.

Fig. 7 is a side elevation of the same in its collapsed or folded condition.

Referring to the drawings by characters of reference, 10 designates a seat, preferably constructed of wood, and having secured to the underside thereof at the opposite side edges the stationary wheel spring supports 11 to which the inwardly foldable wheel supporting springs The main supporting wheels A'are mounted on the stub axles 15 respectively carried by the supporting springs 12, said wheels, when the go-cart is in set-up condition, being disposed in transverse alignment. A guard foot 16 is secured to each supporting spring and projects rearwardly and downwardly therefrom at an angle to afford means for preventing rearward overturning of the gocart by their contact with the ground prior to the overbalancing of the same. A pilot wheel 17 is mounted inarotary fork 18, the shank 19 thereof xtending upwardly through a head 20 secured between the forward extremities of the parallel arms 21 which constitutethe pilot wheel frame. The rear extremities of the arms 21 are pivoted as at 22 to the underside of the forward end of the seat 10, preferably to a transverse strapiron brace 28, the opposite extremities of which are secured as at 24 to the stationary wheel spring supports 11. The upper extremity of the fork shank 19 which extends through the frame head 20 is provided with an enlarged block 25. A long; udinally adjustable tongue is provided and the same consists of tubular inner and outer telescopic sections 26 and AT, the latter having a bifurcated extremity QR'which embraces the block 25 and is pivoted thereto as at The inner section 26 is provided with a handle 30 at its outer extremity which is adapted to afford means for drawing and guiding the gocart. The means for limiting the relative separation of the tongue sections consists of the wires 31 and 3.2.the former being connected as at 33 adj accnt the outer extremity of the inner section, and the latter bein connected as at 84 adjacent the inner end of the outer section. Each of the wires are pro- 12 are hingedas'at 13.

vided with an embracing loop or loops at their free entremi ies which encircle the opposite wire and which co-act with each other when the inner section is extended to afford a stop for limiting the withdrawal of the section 26 from the section 27.

In order to provide means for locking and reta' iinp; the tongue between the arms 21, the outer tongue section 27 is provided with diametrically opposed outwardly projecting; enlargements 36 which are received by the outwardly pressed depressions 37 in the inner confronting faces of the arms 21.

By the arrangement thus far described it is obvious that the supporting wheels 14 and wheel supporting springs 12 may be folded inwardly to overlie each other and the pilot wheel frame withthe tongue arranged between the arms constituting the same may he swung downwardly and rearwardly over the folded supporting wheels to arrange the go-cart in a compact collapsed and folded condition.

y The means for retaining the supporting wheels and the pilot wheel frame in set-up condition includes a slide bar 38 longitudinally shiftable in a groove formed in the underside of the seat 10 and extending throughout the length of said sheet. A crossbar 40 is secure-d to the rear end of the slide bar 38 and the opposite extremities of said crossbar are turned downwardly at a right angle thereto as at 41. The entremities of said down-turned portions are bent to provide the U-shaped embracing fingers 42 which are designed to engage and coact with the upper rearportion of the wheel supporting springs 12 when the slide bar 38 is shifted in a forward direction whereby to loclr and. retain the same injopen position. The forward extremities of the slide bar 33 is turned. downwardly at a right angle thereto as at 43. The arms 21 are provided with

cross straps

44 and 45 adjacent their inner pivoted end, the cross strap 44 being secured therebetween with the upper face thereof flush with the upper edges of the The cross strap 45 is secured in a position to under face flush with the upper sides of th said arms. The forward edge of the cros. strap 44 is designed to lie flush with the forward edge of the seat 10 and the rear edge of the cross strap 45 is spacedtherefrom slightlygreater distance than. the width of the downturns-d extremity 43 of the slide bar 38. The slide bar 38 is retained in the groove by the strap-iron brace 23 and the strap 46, secured to the under side of the seat adjacent the rear thereof. A folding and collapsible back and arm frame is provided and consists of the side rails 47 upon overlie the upper edges of the bars with its" which the wooden arm rests 48 are secured and the connecting back rail 49 is pivoted at its opposite extremities as at 50 to the .the U-shaped fingers 42 from on 3 rear ends of the arm rail, a wooden or other suitable form of bacl: rest 51 being secured to said baclr rail. The back rail is provided with depending vertical rails 52 which are pivoted as at to the upper side the seat adjacent the rear end thereof. The forward extremities of the arm rails 47 are pivoted as at 54 to the rails 55, which are in turn pivoted as. at 56 to the opposite sides of the seat and are provided with extended 8?( tremities 57. The shift bar 38 has connected at the medial portion thereof a crossbar 58, the opposite ends of which are provided with downturned slotted extremities The extended extremities 57 of the rails are each provided with a shift pin 60 which operatively engages the slotted extremity 59 of the crossbar 58 whereby the movements of the back and arm frame to collapse or open the same will simultaneouslyeifect the shifting of the shift bar 38. The movement of the back and arm frame to collapse or fold the same will effect the shifting of the shift bar 38 rearwardly, thereby disengaging the U-shaped fingers from their embracing engagement with the springs 12 and retracting the forward extremity of the shift bar from the position illustrated in Fig. l to dispose the downturned extremity 43 in rear of the rear edge of the cross strap '45 as illustrated in Fig. 5. This permits of the inward folding of the support-i wheels and leaves the pilot wheel frame free to he swung on its pivots 22. The movement of the heel: and frame to open or set-up position effects the shifting; of the shift rod 38 forwardly to loclr and retain the supporting, wheels and the pilotwheel frame in setup condition. A foot rest 61 of any suitable form is carried by the arms of the pilot wheel. frame to afford a means upon when the occupants feet will be supported.

In use and operation, when the go-cart is in set-up condition and it is desired to fold or collapse the same the back and arm frame are swung forwardly on their

pivots

53 and 56 to cause the baclr to be swung downwardly to overlie the seat andto dispose and bring the arm rails 47 and arm rests 43 close to the said seat. This movei it of the back and arm frame effects the rearward sliding movement of the shift bar 38 through the engagement of the shift pin 60 with the slotted extremity 59 of the crossbar 58 secured to said shift bar. The rearward movement of the shift bar sinniltaneously disengages gagement with the frames 12 and retracts the forward extremity of the shit-ft rod to dispose thesame out of engagement with the cross strap 45 and-out of the path of movement thereof whereby the pilot wheel supporting frame may be swung: on its piv? ots 22. The supporting wheels are then swung into overlapping relationbeneath the insane-5 seat and the pilot wheel frame is swung upon its pivots 22 to overlie the overlapping supporting wheels as illustrated in Figs. 6 and 7. The pilot wheel in this position will foroibly engage behind the tire of the outermost supporting wheel, as illustrated in Fig. 7, to frictionally retain the parts in folded. or collapsed condition, and the tongue will be swung between the arms 21 where the same will be retained by the engagement of the enlargements 36 in the depressions 87. This arrangement will retain the gocart in its folded or collapsed condition and permit of the transportation of the same when folded.
