CQLLAIPSIBLE GOCART Application filed. October a, 1928. Serial No. 310,761.

This invention relates to a collapsible or folding go-cart and has for an object to provide an improved construction which may be adjustedto act as a vehicle or adjusted to pre- 1 5 sent a collapsed structure having the appearance andshapeofa suitcase. v Another object of the invention is to provide a go-cart with a body which, when folded, presents the walls of a suitcase and 10 when unfolded presents a body structure including the different supports found in the usual cart. v A further object, more specifically, is't'o provide a folding or collapsible go-cart wherein the legs andother supporting members are readily movable to a point within the body so asto be completely closed thereby.

An additional object is to provide a collapsible go-cart wherein certain parts are formed to present a rectangular housing when. collapsed and to presenta back, bottom and foot-piece when unfolded, the arrangement being such that the wheels and other ,foldingfrnembers are within the body when folded and are capable of being moved to an outeroperative position when the body is unfolded.

Figure 6 is a transverse sectional view through being shown unfolded.

, Referring to the accompanying drawings. by numerals, 1 indicates the bottom, 2 the back and 3 the foot-piece of the go-cart when igure 5 on the line 6-6, the parts in a position as shown in Figure 1, these means when folded presenting the walls or body of the enclosing structure, as shownin Figure 4:, which is in effect a rectangular box. A strap 4 is secured in place so that the enclosure or box may be carried as agrip, and in order to enhance the appearance of the device so that it will appear as a grip suitable edge trimming ar bracing members 5 are pro vided. These members, in addition to giving 6s a pleasing appearance, act as bracing members for bracingor supporting certain of the parts when folded, and also whenunfolded are in an operative position as a go-cart. The bottom 1 is provided with a plurality of strips 6 on which is mounted a plate 7, said plate being of metal or wood or other material, as

preferred. Near the rear of the bottom are arranged strips 6 and 8, said strips supporting a plate 9 similar to plate 7 said strip 8 7.0

acting as a corner member for bracing that part of the bottom. A front strip 10 is secured to bottom 1 in any desired manner and to this front strip the looped ends 11 of the rails 12 are secured by screws or other suitable means. The rear ends of the bars or rails 12 are secured in any desired manner to the thickened portion 13 of the end wall 1 1. A pair of guiding or holdingrodslS and 16 are secured to the respective side plates 17 whichside plates so are connected to the strips 6, as well as to the members .8. and 10. Hook members 18, and 19 coact with bar 16, while identically shaped hook members 19 and 20 coact with rod 15.

all of these hook members and associated as parts are identical, the description of one ;pair of hook members and associated parts will apply to both. As illustrated in Figure 1,1100]; members 18 and 19 are formed integral with the rods 21and 22, thoughthey so could be Inadejseparate and rigidly secured thereto. These rods are positioned to extend downwardly when in use so as to be connected to the plate 23 by rivets, welding, solder or other, desired means. The extreme ends of S the rods ormembers 21 and 22 are bent to form axles Qlfand 25 for receiving the respective wheels 26 and 27. Each plate 23 is provided with an angle bar 29 having apertures and 31for receiving the hook membersBZ r are folded, as illustrated in igure 5.

or ears forming part of the plate 36. The

plate 36 has a threaded aperture through which the screw 39 extends, said screw being provided with a winged head 40. This screw is adapted to be screwed into thethreaded socket 41 (Figure 5) for-med in bottom l and extending into one of the strips 6. As illustrated in Figure 6, when the screw 39 has been tightened the wheel brace 42 consisting of the rods 34, 35, plate 36=and associated f parts act to brace the respective rods 21 and 22 and associated parts, including the wheels 26 and 27. It will be noted thatcaeh of the hooks 18 to 20 is formed with'a slot so that it may be swung from the position shown at theleft in Figure 6 and shown in Figure '1, to theposition shown in Figure 3.

Associated with the bottom 1 is the front or foot-piece 3 which is hingedly connected with the bottoml bya suitable hinge-structure'43,said' hinge structure being shown as an ordinary piano'hinge. The foot portion '3 isformed with what may be termed a bottom section44, anend 45 and sides 46 and 47, said ends'and sides forming one end of the structure shown in Figure 4 and part of theside edges, while the bottom section 44 coacts with bottom 1 to make one of the side members of the structure shown in Fig ure 4, the opposite side member being formed by the back 2. Connected with back 2 are side plates 48 and 49 which coactwith the side members 46 and 47 for completing'the top and bottom members of the structure shown in Figure 4. In order to hold the back 2 unfolded or in an operative position,

as shown in Figure'l, elbow braces 50 are provided, and in order to provide a proper grip for manipulating the go-cart, a curved member 51 is secured to back 2, said curved member being out of the wa when the parts 'tothe position shown in Figure4, the screw 39 is released or unscrewed and then the various hooks 32 and 33 are lifted out of their sockets. The rods 21 and 22 are then swung upwardly so as tobe substantially parallel with the bottom 1 and then the parts are slid over the bottom 1 until the wheels and associated parts are nested, as shown in Fig ure 3. In moving the wheels to this position they'are slid beneath the bars 12. End 3 is then turned up to the position shown in Figure 3 and finally the back- 2 is lowered after the members 50 ave been pushed outward- 1y from a central point, so that they will swing to a folded position. Afterthe parts have been completely folded, as shown in Figures 4 and 5, the lock or clasp 52 is moved able body when folded presenting a rectangular enclosure, said body when unfolded forming the bottom of a cart, a back to the cart and a foot-piece to the cart, hinge members for connecting said parts together, a plurality of pairs of wheels, a frame for each pair of wheels, each of said frames having a pair of rods formed with apertured hookshaped ends, a bar extending through the aperture in eachof said ends, said bars being connected to the top surface ofsaid bottom and extending transversely thereof for slidably and swingably connecting said frames with said bottonn-said apertured ends being so formed that the frames and wheels may be swung to a position substantially parallel with the bottom and then slid to a position over the bottom when the parts are folded and slid and swung to a position so that the frames will extend at right angles to the bottom when unfolded, and means for formed with slotted hooks, said slotted hooks being positioned so that said rods will extend therethrough, traction means carried by each of said frames and a removable brace 'removably connected with each, of said frames and with said bottom, whereby when said brace is functioning the traction means will function and when said means have been removed said frames and traction means are capable of a swinging and sliding movement in such a direction as to be nested on top of said bottom.

3. Acollapsible go-cart, including a body, a pair of swinging and sliding frames connected with the body and capable of being slid to a nested position on top of the body and also slid to a position on one side of the body so as to extend at right angles to the plane of the bod and a removable bracing structure for saic frames, said bracing structure including a plurality of rods extending through each frame, a central plate and a clamping member for clamping the central plate to the bottom of said body.

4. A collapsible go-cart, including means forming a body, a pair of frames, a pair of wheels connected with each frame, a removable brace for bracing said frames, and a each end, each of said frames including a pair of rods having apertured hook ends through Which said bars extend, whereby saidframes' may be swung to a plane sub-- stantially parallel to the plane of said body and then slid longitudinally of said bars over said body.
