20 Claims.

The present invention has for its object the design and construction of a childs go-cart which may be folded or collapsed so that it is easy to carry. The usual non-collapsible go-cart is very awkward and difficult to handle, particularly in getting on or off street cars or buses, especially when the adult has to carry the child and possibly miscellaneous packages. A go-cart made in accordance with the present invention is readily collapsed andcan be manipulated easily in collapsed position. Th construction is such that the go-cart is automatically collapsed after the initial closing operation is performed and will remain in collapsed condition without any tendency to open up. The design is thoroughly practical, and when in collapsed position the entire device is compact, differing in this respect from previous attempts to make a collapsible device of this character.

A further advantage of the design shown herein is that when in collapsed position the supporting wheels are so located as to furnish a stable support for the collapsed go-cart and it may be set on the ground where it will stay in upright condition. Further, the go-cart isso designed that when the collapsing operation is initiated, the go-cart tends to move into its collapsed or flattened condition due to overbalancing the weight of the various elements in the direction in which the elements move for collapsing and, as a result, when the partially collapsed device is lifted from the ground, it will close up automatically. When, however, the go-cart is in its normal or non-collapsed condition, it will not tend to collapse and may be handled and operated xactly as a noncollapsible vehicle of this type.

While the object of the invention has been to make a thoroughly operative and practical gocart which will relieve the parent of much trouble in transporting the child and its go-cart,the invention may be applied to other types of vehicles.

The invention is shown and described in its best known and preferred form, but it is possible that variations and modifications may be made in specific embodiments of the invention without departing from the principles thereof as set forth in the appended claims.

In the drawings:

Fig. 1 is a. front view of a go-cart made in accordance with the invention, the vehicle being shown in full lines in its expanded or open p 1- tion, dotted lines being used to indicate the movement of the seat and footrest which initiates the collapsing operation;

Fig. 2 is a side view of the erected go-cart;

Fig. 3 is a plan view thereof; and

Fig. 4 shows, in perspective, the go-cart in fully collapsed position and standing on the ground.

Referring to the drawings in'detail, the right and left side boards or panels of the go-cart, looking at it from the front, are indicated by the numerals l and 2, respectively; These side boards may be made in any attractive design and each is formed with a forward leg in the lower end :of which is swivelly mounted the caster frame 5 constituting the support for a forward wheel 6.

Midway of the panels is located the horizontal seat 8 With its forwardly extending tongue 9. The seat is connected by the hinges l0 to the side board 2 so that it may be swung upwardly as shown in dotted lines in Fig. 1. When, in its lowered position, the seat rests upon a cross piece or riser l2 which is located substantially midway of the structure and its forward corner remote from the hinges I0 fits behind a bracket I4 attached to the inside of the side board I. Preferably this bracket has a slight spring action which holds the structure rigid when in open condition. The function of the bracket I4 is to serve as a lock whichprevents the two side boards from shifting with respect to each other. A handle I1 is attached to the under-side of the seat near its free or unhinged end. When the go-cart is collapsed, the handle is accessible above the assembly and is the means by which the device is carried.

Forwardly of the device and located at the lower end of the legs 4 is the footrest l8 which is also hinged to the side board 2 at I9 so that it will swing upwardly with the seat 8. A chain 20 is attached to the underside of both elements and connects the parts so that they will move in unison. In lowered position, the unhinged end of the footrest is supported on a bracket 22 attached to the leg 4 of th side board I. As shown in Fig. 4, the seat 8 and the footrest l8 are so arranged and designed that when they are moved to vertical position they will not interfere, but will lie flat against the inside of the side board 2. The fact that the chain is attached to the underside of the footrest causes the latter to lie flat against the side board 2 when the device is collapsed.

The main portion of the back of the go-cart is indicated at 24, being hinged at one end to the side board lat 25 by a plurality of vertical hinges. The back does not extend completely to the side board 2, being supplemented by afiller piece 26 to which it is hinged as at theseveral points 28. The filler piece is slightly wider than the thickness of the seat and footrest so as to accommodate the parts between the side boards I and 2 when the go-cart is collapsed. This filler piece is coextensive with the back so that the axle is supported uniformly between the wheels when the device is erected. It will be noted that the hinges and 28 are reversed so that in the collapsing movement the side board 2 will move to the right of the side board I. The riser or seat rest I2 is likewise hinged at one end to the side board I as at 29. At its other end, the riser is likewise hinged at 30 to a filler 32 of the same thickness as the filler 26. Across the upper front of the side boards is located the bar 34 which may carry a number of colored rings 35 to amuse the child. This bar 34 is hinged similarly to the parts I2 and 24 to the side board I at 36 and at 31 to a bracket 38 attached to the side board 2. This bracket extends outwardly from the side board 2 to bring the hinge 31 in line with the

hinges

28 and 30.

To the lower end of the back 24 is attached the rear axle 40 which carries the rear wheels 42. From an inspection of Fig. 4, it will be seen that when the go-cart is collapsed, the rear wheels 42 are in a line which is midway between the front wheels 6, and this makes a three-point support for the collapsed device so that it will be stable when set down in this position and will not tend to tip. over. This facilitates the handling of the collapsed go-cart.

The handle of the go-cart is indicated at 45. It is removably attached to the rear side of the back 24 by a diagonally arranged clamp bracket 46 which may be of any preferred design. As

shown in the drawing, this bracket consists of the stationary block 48 and the movable plate 49 hinged at 53. The part 49 is held against part 48 by the wing nut unit 50 to secure the handle. When the go-cart is to be collapsed, the handle is removed and after the device is folded up the handle is conveniently attached in horizontal position alongside the assembly by clips 52 attached to the side board I. The handle is usually only slightly longer than the over-all length of the collapsed go-cart so that it does not project objectionably beyond either end of the assembly.

It will be seen that the collapsing and re-erection of the go-cart is verysimply and easily done. The handle 45 is first detached, then the seat 8 is raised and the footrest moves with it. The side boards I and 2, the back 24, the riser I2 and the cross bar 34 now are parts of a parallelogram.

The assembly is then picked up by the handle I1 and as the preponderance of weight is to the right of the device as shown in Fig. 4, the whole structure will fold together automatically. As shown in Fig. 4, the handle is located forwardly of the seat so as to accentuate the unbalanced condition of the assembly and thus insure its collapse and also its tendency to remain in collapsed condition. In collapsed position the seat and footrest will lie against theside board 2, while the back 24 and the riser I2 will be against the side board I. The front bar 34 will lie in the plane of the parts 24 and I2. This makes a very compact, three-layer assembly which is easil handled and which requires no holding device to retain it in collapsed position. The handle 48 may be attached at any convenient point when the device is collapsed, the location shown in Fig. 4 being admirably suited for the purpose.

It will be appreciated that the device as. described herein is one form in. which the invention is embodied, but that changes, modifications and improvements may be made therein without sacrificing any of the basic principles of the invention. The invention is not necessarily limited to go-carts or even to childrens vehicles, but may be employed in other devices where it is desired to collapse the device for compactness and ease of handling.
