Claims.

My invention relates to an improvement in conveyances such for example as gocarts for children. One purpose of the invention is the provision of such a gocart which is made of noncritical material.

Another purpose is the provision of a gocart made substantially of wood;

Another purpose is the provision of improved spring means for such a gocart Another purpose is the provision of improved means for mounting the wheels of a gocart;

Another purpose is the provision of an improved tray for a gocart;

Another purpose is the provision of an improved handle and improved means for securing it to the gocart.

Other objects will appear from time to time throughout the course of the specification and claims.

My invention is illustrated more or less dia grammatically in the accompanying drawings, wherein:

Figure 1 is a plan view;

Figure 2 is a side elevation;

Figure 3 is a section along the line 3-3 of Figure 1 on an enlarged scale;

Figure 4 is a perspective of the tray;

Figure 5 is a section on an enlarged scale along the line 5-5 of Figure 2;

Figure 6 is a section on an enlarged scale along the line 6-43 of Figure 1;

Figure 7 is a section taken on the line 17 of Figure 6; and

Figure 8 is a section on an enlarged scale along the line 8-8 of Figure 2.

Like parts are indicated by like characters throughout the specification and drawings.

Referring to the drawings, I illustrate a pair of side elements I, which are connected for example by the seat bottom 2 to which the side elements may be screwed or otherwise secured. 3 is a foot bar extending between the side elements I. It-may be screwed, nailed or otherwise secured to them. 4 is an intermediate bar extending between the side members I and bridging the gap between the foot member 3 and the seat bottom 2. Extending upwardly from the seat bottom are the elements 5 which are connected as by a back member 6. Referring in greater detail to the side members, it will be observed that they each have upper surfaces 1 which abut against the bottom of the seat bar 2. Slanting downwardly and forwardly in relation to it is a bottom surface 8 which extends into a rather sharply inclined intermediate edge portion 9 which in turn terminates in a generally horizontal bottom edge II). The portion 9 is cut away or slotted horizontally as at II. In the cut away portion I I of each of the side bars I, a spring structure indicated as I2 is inserted. The spring is herein shown as of two leaves. It will be understood that if desired, a single leaf structure may be employed. This structure may advantageously be made of wood but it may be understood any other suitable member may be employed. Both leaves are held in place by a plurality of dowels I3. They may be glued also. It will be understood that where two leaves are employed, the leaves should be free along the portion oftheir length which is exterior to the slot II. The lower leaf I2a has secured to it a block I4. This block may be channeled at the top to receive the leaf I2a. Extending between these blocks is any suitabletransverse support or axle I5, preferably fixed in relation to the blocks. I may for example employ a dowel I6 which extends downwardly through both leaves through the block and through the axle I5. The dowel may be glued to the axle and the block and the lower leaf but the upper leaf I2?) is preferably free to flex in relation to the lower leaf and is penetrated by an aperture l6! large enough to prevent contact between the dowel and the edge of the aperture. Any suitable wheels I1 may be rotatably mounted on the exterior ends of the axle I5 and may be held against outward movement for example by washers I8 and securing pins or dowels I9. If desired, bearingwashers may be inserted between the wheels and the blocks. It will be observed as in Figure 2 that there is a clearance between the upper side of the spring and the lower surface 8 of the members I. Thus the springs may freely flex to accommodate the weight of the child in the conveyance.

I illustrate a handle structure including a pair of handle side elements 25 which are outwardly flexed apart at their upper endsand are con-- nected by a hand piece 26 in place. The lower portions of the member 25 may be secured together. It may be advantageous to have an intermediate spacer or strengthening member 21. The parts may be doweled or otherwise secured together and glue could be employed. If the side pieces 25 are made of wood, they naturally tend to spring together which assist in holding the member 26 firmly clamped in position. In order to secure the handle to the bottom of the cart, I may employ a foot bar 28 secured to the bottom 3 and to the side members I. It may be somewhat channeled as at 29 to receive the lower portion of the handle. The bottom of the handle may be inclined as at 30 to conform to the upper surface of the member 3. A single securing bolt 3| and a thumb nut 32 may be sufficient to hold the handle firmly clamped in place as the handle stays seated in the channel 29, and abuts firmly against the bottom 30 of the car.

I may find it advantageous to have a removable tray, although a solid or unremovable tray may be employed. As an example, I illustrate a tray portion including a transversely extending bar 35 having rearwardly extending arms 36.

which conform to the exterior of the side members 5. Each arm member has an inwardly securing pin or dowel 3'! which may fit into an exterior slot 38 on one of the side bars 5. As illustrated in Figure 3, each such slot includes an upper portion 33a and a bottom portion 68b connected by a rearwardly inclined curved portion 380. The forward edges of the side bars 5 are also notched as at 39 to receive the rear edge of the bar 35 when the parts are in the position in which they are shown in Figure 3. The tray is firmly locked in position. It can be removed by tilting the arms 36- upwardly until the pins meet the inclined or curved. portion 360. This will cause or permit forward movement of the bar 35 which may move sufficiently far forwardly to clear the notch 99.

It will be realized that while I have shown and described an operative device, still many changes in size, shape, arrangement, number and disposition of parts may be made without departing materially from the spirit of my invention. I wish, therefore, that my showing be taken as in a large sense diagrammatic.

I claim:

1'. In a wheel vehicle and spring structure therefor, a pair of generally parallel longitudinally. extending side frame members lying in generally vertical planes, means for connecting said side frame members, the side frame members being downwardly enlarged intermediate their ends, leaf springs extending longitudinally rearwardly from said downward enlargements, said leaf springs having free rear ends, a wheel axle connecting the free rear ends of said springs, and wheels on said axle.

2. In a wheel vehicle and spring structure therefor, a pair of generally parallel longitudinally extending. side frame members lying in generally vertical planes, means for connecting said side frame members, the side frame members being downwardly enlarged intermediate their ends, leaf. springs extending longitudinally rearwardly from said downward enlargements, said leaf springs. having. free rear ends, a wheel axle connecting the free rear ends of said springs, and wheels on said axle, said leaf springs being at their forward ends secured in recesses in the downward enlargements of said side frame members.

0.111 a wheel vehicle and spring structure therefor, a pair of generally parallel longitudinally extending side frame members lying in generally vertical planes, means for connecting said side frame members, the side frame members being downwardly enlarged intermediate their ends, leaf springs extending longitudinally rearwardly from said downward enlargements, said leaf springs having free rear ends, a wheel axle connecting the free rear ends of said springs, and wheels on said axle, each said side frame member having a lower surface diverging upwardly and progressively from the horizontal and adapted to receive said leaf springs throughout a substantial range of fiexure of said springs.
