WALTER H. MOORHEAD Fig. 7 BYZ/MV ATTORNEYS embodiment of this invention;

l VELOCIPEDE Walter H. Moorhead, 4939 Donald Ave., Richmond Heights, hio Filed Mar. 3, 1958, Ser. No. 718,537 6 Claims. (Cl. 272-33) This invention pertains to toys, and more particularly, to a velocipede which may be ridden by a small child.

Small children enjoy toys which bounce, such asv hobby-horses. They also enjoy toys which may be ridden and moved.

One of the principal objects of this invention is to provide a toy which may be ridden by a small child along a preselected path and in which movement is caused by the child bouncing on a seat to combine both the features of a bouncing toy and a moving toy.

Moving toys such as velocipedes often create problems for parents or guardians. When riding such a vehicle indoors small children are apt to damage furniture by bumping into it, and when riding a velocipede in the outof-doors they are apt to travel into the path of moving vehicles.

Accordingly, another object of this invention is to provide a velocipede type toy which travels over a preselected circular path to prevent any possible injury to furniture or the child riding the toy.

A further object of this invention is to provide a simple rugged tripod suspension for aA toy made in accordance with the foregoing objects, to provide a toy having good stability which will remain in anupright position and not turn over when it is ridden by a child.

Another object of the invention is to provide a velocipede type toy which has greater stability than a tricycle, but which has the simplicity, ruggedness and mobility of a bicycle.

An additional object of the invention is to provideY a toy having a pivot, a frame joined to the pivot by joining means so that movement of the frame is in a circular path about the pivot, and rst and second spaced Wheels nited States- Patent supporting the frame and joining means with the axes of the Wheel located radially with respect to the pivot to aid in causing the device to move in a circular path.

Still another .and more specific object of the invention is to provide novelgand improved means to limit the wheels to unidirectional rotation, the means being in the Vform of snubbers which frictionally engage the peripheries `of the wheels to prevent reverse rotation of the wheels.

A rstill further object of the invention is to provide a novel and improved velocipede device in which a spring Vis provided to serve a dual function of frame and carriage for a seat orY other support for the child and urging means lto translate the bouncing movement of the child intoV forward movement of ythewheels and therefore the frame and other parts of the velocipede. p

.Yet another object of the invention is to provide a Anovel unitary seat, handle, and stirrup assembly which in' on the pivot to increase the stability of the device.

Other objects and a fuller understanding of the invention may be had by referring to the following description `and claims taken Yin conjunction with the accompanying drawings, in which: u

FIGURE 6 is an enlarged sectional view of the pivot as seen from the plane indicated by the lines 6 6 of FIGURE l; and

FIGURE 7 is a side elevational view of a modied form of the invention.

In the drawings, and in FIGURES 1 and 2 in particular, a preferred embodiment of the new andnovel velocipede lis shown. The term velocipede has come to mean a'tricycle. However, its original meaning, and the meaning in which it is used in connection with this invention, is in the sense of any of various bicycles or tricycles. lIn fact, it is used in the sense of a wheeled toy vehicle which may be ridden by a child.

'The velocipede in its preferred embodiment of FIG- URES 1 and 2. has a spring frame 10 of generally circular configuration. As can best be seen in FIGURE 1,

the spring frame 10 is substantially semicircular in its preferred form. The spring frame 10 has rst andjsecond ends 11, 12. which are fixed to first and second pivot bars 13, 14 respectively. The pivot bars or arms 13, 14 have ends which are pivotally connected to a pivot Ashown generally at 15. First and second wheels 17, 18 are rotatably connected to the frame 10 and pivot bars 13, 14 in a matter which will subsequently be described in more detail.

The wheels 17, 18 are preferably canted inwardly somewhat at the top with their axes being substantially extensions of the axes of the pivot bars 13, 14 and radial with respect to the pivot 15. It will be seen that as the device is advanced and the wheels 17, 18 rotate, they follow a circular path about the pivot 15.

In FIGURE 4 the connection of the Wheel 18 to the pivot bar 14 is shown on an enlarged scale. References to FIGURE 4 will show that the pivot bar 14 is a tu- An axle bar 20 projects into the tube 14. The axle bar 20 is xed to the tube 14. The wheel 18 is journaled on the axle bar 20 with .a bearing forming part of the center portion 22 of the wheel 18 in rotatable contact with the axle 20. A hole 23 is formed in the end of the axle bar 20 and a cotter key 24 is disposed in the hole 23 to hold the wheel 18 on the axle. The wheel 18 has a rubber rim 25 to limit noise when the device is in operation and to prevent undue wear of the surface upon which the velocipede is being operated. It will be recognized that the wheel 17 corresponds in mounting and construction to the wheel 18.

A child, or operator, support assembly is shown generally at 30 in FIGURES l, 2 and 3. The assembly 30 has a stirrup bar, or pressure transmission bar 31 which straddles the frame 10 and provides lirst and second foot supports 32, 33t. A seat 34 and a handle bar 35 are also provided and form a part of the operator ,support assembly 30. The seat and handle bar 34, 35 are preferably of unit construction which unit together wtih the stirrup bar 31 is joined to the frame 10 by a single bolt 36.

In FIGURE 6 the details of a simple and novel pivot 15 are shown. A pivot support 40 is provided. A rub- .ber cup 41 is telescoped over the base of the pivot support to provide friction to hold the pivot in place and protection for the surface on which the device is used. VA bolt 42 is passed through apertures in the pivot bars -wheel rotation. A simple mechanism devoid ot' gears or other intricate parts is provided to permit the vehicle to move forward only. i`First and second snubbers 45,

46 are fixed to the `frame .10. The snnbbers 45, 46 which may be formed of spring steel, have end portions 47, 50 which lie in planes other than radial to the wheels 17,

18. The end portions 47, 50 have blunt edges 49, 48

which are urged into peripheral contact with the wheels 17, 18 respectively. The springing action of snubbcrs 45, 46 urges the blunt ends 49, 48 into lfric-.tional contact with the peripheries of the wheels 17, 18 to permit forward rotation of the wheels and prevent reverse rotation of the wheels. It will be seen that the ends 49, 48 may -be formed of rubber to increase the trictional resistance between the snubbers and the wheels.

In operation a child sits on the seat 34 with his feet in the stirrups 32, 33. He bounces on the seat to make the velocipede advance along a circular path about the pivot 1S. When he `comes down on the seat 34, it causes the ends 11, 12 of the spring frame 10 to spread. The spreading of the spring frame 10, causes spreading of the pivot bars 13, `14 and rotation of the connected wheels. Since the snubber 45 prevents reverse rotation of the wheel 17, all the spreading movement is taken up by a front wheel 18 which rotates in a forward direction. As the spring frame returns to its original position and the child rises, the ends 1-1, 12 of the spring `frame 10 Iand the connected pivot bars 13, 14 are drawn together. As the trarne ends 11, 12 are drawn together, the front wheel is prevented from rotating in a reverse direction b-y the snubbing action of the snubber 46 and therefore all the movement is taken up by the rear wheel `17. The rear wheel 17 thus advances, moving the child further along his circular path. As the child continues to bounce, he continues to advance in a circle with first the front wheel advancing and then the rear wheel advancing.

Stop means may be provided to the expansion of the spring frame 10 and prevent damage by too large a child. This stop means may take the form of a chain 52 which is iixed to both of the pivot bars 13, 14.

The overall stability ot the device is enhanced by several contributing factors. Locating the wheels 17, 18 so they rotate along 'axes which are radial with respect to the pivot 15, aids in holding the device so it operates in a fixed circular path. This permits a parent to leave a child riding the toy unattended knowing that he will not strike turniture if the device is being used indoors, and will not advance his toy to a dangerous place such as in the path of vehicles if the toy isA being used outdoors.

Another of the factors which contributes to the stability of the device, is the canting ot the wheels inwardly as is best seen in 'FIGURE 2.Y This is accomplished by the simple expedient of providing a low pivot 15, so that the pivot bars 13, 14 slope downwardly toward the pivot. This keeps the center of gravi-ty of the child and the toy within the tripod defined by the pivot and the wheels 17,

18 and therefore minimizes any possibility that a child l operator might upset the device.

In FIGURE 7 an alternate embodiment of the invention is shown which has both the attribute ot being stronger than the embodiment of FIGURES 1 and 2 to accommodate a larger child, and the advantage of simulating a girls bicycle. In this constructiomthe spring frame 10 has lirst and second end portions 54,

55 which are xed to the pivot bars 13, 14. Spring por- 4 58 by tirst and second support portions 59, 60 respectively. It will be seen that the spring frame 10 of the embodiment of FIGURE 7 is somewhat M shaped.

I-n the central region ot the M-shaped spring frame 10', a reenforcing brace 62. is provided. The reenforcing brace 62 is somewhat Ushaped and is connected to the base portion 58 and the support portions, 59, 60 to strengthen the spring frame 10".`

A seat 34 and a handle bar 35 are connected to the ends of the brace 62. A lfoot or stirrup pad 63, which can serve as a pressure transmission bar, is provided. The stirrup pad 63 is located in the vicinity of the connection or the base portion 58 and the brace 62.

While the invention has been described with a great deal of clarity and detail, it is believed that in its simplest form it comprises operator control frame and propulsion means which maybe ridden by an operator, wheel means connected to the frame, and a pivot with joining means connecting the trame to the pivot so that the device operates in a circle under urging by the operator.

Although the invention has been described in its preferred form with a rtain degree of particularity, it is understood that 4the present disclosure of the preferred forrn `has been made only by way of example and that numerous changes in the details of `construction and the combination and arrangement of parts may be resorted to without departing from the spirit and vthe scope of the invention as hereinafter claimed.
