Application December 22, 1952, Serial No. 327,212

4 Claims. (Cl. 27257) The present invention relates to improvements in a childs jumping toy.

lt is the principal purpose of the present invention to provide a toy which may be used by children for jumping comparatively long distances.

It is a further purpose of the invention to provide a jumping toy which has no sharp projections that could injure the child operating it.

The present invention utilizes a U-shaped bar with rubber cushions on its lower ends. The child grasps the horizontal section and swings under the bar. The spring filled legs compress under his weight and as he swings outwardly he is given a boost along the ground. There are no sharp handle pieces which could injure the operator if he fell upon the device.

The details and objects of the invention appear more fully in the following description and the accompanying drawings wherein a preferred form of the invention is shown. The description and drawings are illustrative only, however, and should not be considered as limiting the invention except insofar as it is limited by the claims.

In the drawings:

Figure l is a View looking at the invention from the front;

Figure 2 is a side view of the invention looking in the direction of the line 2-2 of Figure 1;

Figure 3 is a diagrammatic view showing how the device is operated;

Figure 4 is an enlarged sectional view taken on the line 4-4 of Figure 2;

Figure 5 is an enlarged sectional View taken on the line 5-5 of Figure 1;

Figure 6 is an enlarged sectional view taken on the line 6-6 of Figure 4; and

Figure 7 is a sectional View taken on the line 7-7 of Figure 5.

The invention comprises a tubular pipe 10, bent in the shape of a U so that it has two depending arms 11 and 12 connected to a horizontal portion 13. Two legs 14 and 15 are adjustably mounted at the lower ends of the arms 11 and 12. The legs 14 and 15 each have a plurality of apertures 16 at their upper ends. At the lower end of each arm 11 or 12, a small boss 17 is formed inside of the pipe. A threaded aperture 18 is formed in the boss and a similar although not threaded aperture 19 is formed on the opposite wall of the arm 11 or 12. A bolt 19a is run through the apertures 19 and 16 and threaded into the aperture 18 in the boss 17 to hold the leg 14 or 15 in place.

Each of the legs 14 and 15 is provided with a channel 20 in which the boss 17 can slide up and down. This insures alignment of the apertures 16 in the legs with the ice opposed apertures 18 and 19 in the arms when the legs are inserted in the arms. The legs 14 and 15 extend down into two tubular spring supports 21 and 22. These spring supports are closed at the bottom and are provided with resilient cushions 23 and 24. In each of the supports 21 and 22 there is a spring 25 of suitable strength. Each of the legs14 and 15 has a slot 26 extending lengthwise thereof to receive a securing pin 27. The pin 27 is made up of two pieces 27a and 27b. The piece 27a has a reduced threaded end 28 which threads into a threaded socket 29 of the piece 2711.

In operation the child uses the device in the manner i1- lustrated in Figure 3. His weight on the top cross piece 13 will compress the springs 25 as he swings forward and the springs will in turn expand after the childs body has gone past the mid position so as to give him an additional impetus forward.

It is believed that the nature and advantages of the device will be apparent from the foregoing description.

Having thus described my invention, I claim:

1. A childs jumping toy consisting of a substantially U- shaped handle bar, having only two tubular parallel arms, a leg having one end telescoped with each arm and a ground engaging tubular arm telescoped with the other end of each leg, a coiled spring under compression bearing against one end of each leg and housed in the tubular arm telescoped therewith, said leg having an elongated.

slot therein terminating adjacent to the end against which the spring bears, and a pin extending through the slot and lixed to the spring housing arm.

2. A childs jumping toy consisting of a substantially U-shaped handle bar, having only two tubular parallel arms, a leg having one end telescoped with each arm and a ground engaging tubular arm telescoped with the other end of each leg, a coiled spring under compression bearing against one end of each leg and housed in the tubular arm telescoped therewith, said leg having an elongated slot therein terminating adjacent to the end against which the spring bears, and a pin extending through the slot and lixed to the spring housing arm, the end of the leg most remote from the spring being adjustable lengthwise of the tubular arm with which it telescopes.

3. A childs jumping toy consisting of a substantially U-shaped handle bar, only two extensible legs one leg being secured to each end of said bar, and a coiled spring in each leg normally holding it extended.

4. A childs jumping toy consisting of a substantially U-shaped handle bar, only two extensible legs one leg being secured to each end of said bar, and a coiled spring in each leg normally holding it extended, each leg cornprising a portion fixed to the handle bar, a spring support portion telescoped with the xed portion and having its outer end closed, a spring under colnpression between the closed end of the spring supporting portion and the adjacent end of the fixed portion, and means connecting said portions to prevent the spring from forcing the portions apart.
