JUMPING TOY Filed Dec. 7, 1959 5 Sheets-Sheet 3 INVENTOR. ISIDOR WEINBERG ATTOPNZ'Y 3,911,782 .l'UMPlNG TOY Isidor Weinberg,.2054 SW. 22nd Terrace, Miami, Fla. Filed Dec. 7, 1959, Ser. No. 857,653 3 Claims. (Cl. 27257) This invention concerns an exercising device particularly adapted for exercising muscles of legs, arms and back of an adult or child.

According to the invention there is provided a platform supported by springs upon a support. A handle bar is provided which can be gripped by an adult or child while standing on the platform. The handle may be secured to the platform by a spring, chain or rope. The user of the device jumps up and down and shifts his weight various directions on the platform while the platform tilts and vibrates due to its spring mounting. The user may also grasp the handle bar and push or pull it against resistance offered by the spring or chain to exercise his back, shoulder and arm muscles.

One object of the invention is to provide a frame structure and a platform connected to the frame by a plurality of radially arrayed springs, the number of springs being variable.

A further object is to provide an exerciser including a rame structure having a pair of crossed bars secured to each other in fixed mutually perpendicular positions by a spider disk, the bars having bent upstanding portions supporting spring hanger frames, and a platform having further spring hanger frames extending radially therefrom with springs connecting the hanger frames attached to the platform and frame bars.

A still further object is to provide an exerciser of the character described with a handle bar connected by spring means to the platform and being movable by pushing or pulling with respect to the platform.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

FIG. 1 is a perspective view of an exerciser device embodying the invention.

FIG. ll is a fragmentary plan view of a frame bar showing the spring hanger of FIG. 10 mounted on the bar.

FIG. 12 is a perspective view of a platform and handle bar connected to the platform by spring means.

Referring to FIGS. 1-8, there is shown a platform 23 including a circular top plate 22 and a cylindrical flange or skirt 24 depending around the periphery of the top r. m a s hate Patented Dec. 5, 1%81 plate. The top plate has ribs or corrugations 23, 29 formed therein in any desired pattern to provide a nonskid or non-slipping upper surface. Holes 3% are formed in the top plate near the periphery thereof. The holes are spaced circumferentially 90 apart. Engaged in the respective holes are hooks 32 formed at ends of spring hanger frames 34. Each hanger frame, as best shown in FIGS. 1, 2, 7 and S, is formed from a wire bent to triangular form. The free ends of the wire are juxtaposed at the apex of the frame and are bent to form the hook 32. The wide base ends 33 of the hangers 34 are formed with a plurality of loops 35 on which are engaged the inner hooked ends of helically coiled springs 38. The springs are axially horizontal. The outer hooked ends of the springs are engaged in loops 39 formed at the base ends 4-9 of further spring hanger frames Each hanger frame 52, as best shown in FIGS. 1, 2 and 6, is formed by a single piece of stifl wire bent to generally trapezoidal form. The free ends 44- of the wire are spaced apart and are disposed in alignment parallel to the base end 417. The free ends 44 of each hanger are engaged in holes 46 formed near the upper ends of two frame bars 48 and 5 8-. Each frame bar has an upwardly and outwardly inclined short arm 45 at its outer end. The intermediate sections 4%, 51 of the frame bars are horizontal. Corrugated rubber friction pads 53 are disposed on the sections 49, 51 to support the frame structure and the device.

Brace bars 69 connect the arms 45 at obtuse angles with the sections 49, 51, respectively, to reinforce the structure. The arms 45 serve to elevatethe platform so that the platform is suspended and supported horizontally by the radially arrayed springs 38 and hangers 34, 42 for vertical and tilting movements.

The horizontal sections 49, 51 are each flattened at the center at 55 and 57 as best shown in FIGS. 4 and 5, respectively, so that the sections 49, 51 of bars 48, 50 can be disposed in crossed arrangement 90 to each other. A circular spider plate 54- having perpendicularly disposed ridges 64 formed therein fits over the central portions of sections 49, 51. A bolt 66 extends through registering holes 55 57- in the flattened portions 55, 57 and in spider plate 54. A nut 67 on bolt 66 secures the plate 54 and bar sections 49, 51 together. Further bolts 68 passing through registering holes in the spider plate and bars and secured by nuts reinforce the assembly.

Secured at the center of the platform by a bolt 74 and nut 76 is a tube 78 as best shown in FIGS. 1 and 3. This tube extends axially upward. A coil spring 80 is disposed at the bottom of the tube and is held by the head of bolt 74. The spring can be compressed and extended against spring bias axially of the tube. The upper end of the spring is engaged in the bottom end of a sleeve 73 slidably fitted in the tube. The upper end of the spring 80 extends radially outward of the tube at 84 through a longitudinal slot 77' in the wall of the tube; see FIG. '1. A shaft 75 is telescopically fitted in the sleeve and can be lengthened or shortened by selectively positioning bolt 79' in holes 83 in the shaft. A handle bar 82 is secured to and extends horizontally perpendicularly to the top of vertical shaft 75. A nut 81 is secured on bolt 79.

In operation of the device assembled as shown in FIGS. 1-4, an adult or child can stand on the platform 20 and jump up and down thereon while steadying himself by holding on to the handle bar. The exercise can'be supplemented by pushing down and pulling up on the. handle bar against the bias in the spring 80. Alternatively, one can sit astride on the platform and operate the handle bar up and down While pushing up and down with his legs. Another beneficial exercise is to place one leg upon the platform, the other resting on the floor or ground, then push down on the platform with the one leg, then lift the leg and permit the platform to right itself. This action can be repeated rhythmically. At the same time the user can push or pull the handle bar in its supporting tube 78 to exercise his arm, shoulder and back muscles. Many other exercises as will readily occur to the user can be performed with the device.

If desired, the rigid shaft 75 and spring 8t; can be replaced by a rope or chain, which will have a maximum limit of extension. The rope or chain will be attached directly to the platform. As a further alternative a coil spring 85 may be attached by an eyebolt 87 directly between the handle bar 82 and platform 24 as shown in FIG. 12, so that the handle bar can be moved in various directions in addition to up and down, against spring tension.

MG. 9 illustrates an alternative form of spring hanger 34 formed from a flat metal plate 89 having a generally triangular form with a hooked apical extension 32 Holes 7 90 provided at the base edge 91 of the plate 89 may receive the hooked ends of springs 38.

FIGS. -10 and 11 show another form of spring hanger frame 42 formed from a single piece of sheet metal. The

hanger has a trapezoidal plate body 92 with depending.

'Hangers 42 can be used in place of hangers 42 and hangem 34 can be used in place of hangers 34.

Since each hanger has a plurality of holes or loops, the number of springs 38 engaged on the hanger may be varied depending on the springiness desired in the platform on which the adult or child stands or sits While using the device.

The assembled exerciser can easily be disassembled for storage or shipment with the use of only common tools such as a screwdriver or wrench. Assembly of the exerciser is equally simple. The device is rugged in construction and economical to manufacture. Broken or damaged parts can readily be replaced. The several springs can be replaced by stronger or Weaker springs.
