Application June 16, 1954, Serial No. 437,055
6 Claims. (Cl. 46-114) This invention relates to toys and more particularly to push toys.
It is an object of the invention to provide a push toy comprising a propelling stick having a moving object thereon such that the object is propelled upwardly along substantially the entire length of the stick to ring a bell as the toy is propelled by means of the stick.
It is another object of the invention to provide a push toy in accordance with the first object having an extremely simple, practical, and cheaply manufactured mechanism for furnishing the described effect.
Other objects and features of the invention will be apparent from the detailed description hereinafter set forth.
In brief, my invention comprises the combination of a stick secured to a push toy body and a pair of wheels carried by the body wherein the wheels have studs or pins for periodically engaging a freely slidably element on the stick and releasing the element. By providing a compression spring at the lower end of the stick, the slidable element is thus forced to compress the spring; when the element is released it slides up the stick almost to the very end to strike a bell mounted near the stick handle. Subsequently the element, which may be a disc or ball of any suitable material, slides down the stick, motivated by gravity, and is once more engaged by the pins to compress the spring for automatic repeat action.
A detailed description of my invention will now be given in conjunction with the appended drawing, in which:
Fig. l is a plan view of the push toy.
Fig. 2 is an elevation showing the toy with one wheel removed to disclose details, and
Fig. 3 illustrates a modification.
With reference to the forms shown in Figs. 1 and 2, tny toy comprises a stick 10 secured to a wooden body 12 in any suitable manner. The body 12 may be made of one or two pieces, thus a front piece 14 secured to a bottom piece 16, or the body and stick may be moulded integrally or stamped of sheet metal.
The body carries a pair of wheels 20 keyed to an axle 22 for rotation in unison. Spacer elements such as 24 may be utilized to maintain a proper centering of the wheels with respect to the body.
The wheels carry abutment means such as pins 28 for a purpose to be hereinafter described.
Mounted at the lower end of the stick is a light gauge compression spring 32 of any suitable material such as steel or plastic. A disc 34 having a bevelled surface 36 is freely slidable on the stick and is so disposed that as the toy is propelled the pins 28 will engage the bevelled surface and move the disc in the direction shown by the arrow in Fig. 1. Thus, the disc is forced downwardly to effect compression of spring 32. After the pins 28 have reached some position such as 28, it will be apparent that they will leave the surface of the disc, permitting sudden expansion of spring 32. This causes the disc to slide up the stick and strike a bell 34' adjacent the knob handle 36'. I have found in practice that it is possible with any suitable spring to cause a wooden disc about 2" nited States Patent ice in diameter and /2" thick at the hub to slide a distance of some 20" on a /s diameter dowel stick. Accordingly, a very effective spectacle is achieved.
Preferably the pins 28 are axially aligned with each other so as to balance the force on the disc and the length of the spring is such, together with the disposition of the stick, that the pins are at the high point of their are of travel when the spring is compressed about half way of the total degree of compression to which it will be subjected prior to disengagement of the pins from the disc. Thus, the dotted arc in Fig. 2 illustrates this preferred condition.
Attention is now invited to Fig. 3 showing in elevation a modified form of wheel wherein the wheel is mounted off-center. This, in addition to having a novel effect visually also provides some mechanical advantage to the extent that the distance D1 from the pin 28' to the axle 22' is much smaller than the distance D2 from the axle to the ground. Thus, a mechanical advantage results which is greater in magnitude than the mechnical advantage achieved by comparing the same distances for a wheel rotated at its center as in the form shown in Fig. l.
The spring preferably has its lower end secured either to the stick as shown or to the body; however, it could have its'upper end secured to the disc so as to move with the disc, or the spring could be unsecured.
My toy may be constructed of any suitable materials such as wood, metal, fiberboard, etc., as will be apparent. Further, the rims of the wheels may be provided with suitable frictional material if required to prevent skidding, depending upon the strength'of the spring required for any given weight of the slidable element.
Having described my invention, I am aware that various changes may be made without departing from the spirit thereof and accordingly I do not seek to be limited to the precise illustration herein given, except as set forth in the appended claims.
1. A push toy having a handle comprising an elongated upwardly inclined push stick for propulsion, wheel means adjacent one end of said stick, abutment means carried directly by said wheel means and protruding therefrom, stressable potential energy means disposed to be periodically stressed and released by said abutment means when said toy is propelled to effect rotation of said wheel means, and an element carried by said stick and movable relative thereto, said element being motivated by said potential energy means upon release by said butment means, wherein said movable element is freely and gravitationally slidable on said stick, and a bell adjacent the other end of said stick disposed to be struck by said element, wherein said element is propelled upwardly on said stick by said potential energy means to strike said bell and subsequently propelled downwardly on said stick by gravity.
