RESILIENT JUMPING SHOES Filed May 15, v 1959 INVENTOR. ALBERT J. HORTEN BY @ZZ MMM/ ATTORNEYS United States Patent RESILIENT JUMPING SHOES Albert J. Horten, 3020 E. Derbyshire Road, Cleveland Heights, Ohio Filed May 13, 1959, Ser. No. 812,946

4 Claims. or. 36-73) This invention relates to exercising toys, and more particularly to resilient jumping shoes. This is a continuation-in-part application of an application filed Octoher 1, 1958, by me, Albert J. Horten, bearing'Serial No. 764,729, entitled Jumping Devices and now abandoned.

Exercising toys of this type are not only enjoyable but they are also helpful to a child. While they provide the child with a form of amusement, they are also providing the child with needed and necessary exercise. It is, of course, desirable to have such a toy as safe as possible to prevent injury to the child.

Therefore, one of the principal objects of this invention is to provide an exercising toy that supports both the heel and ball of the foot'with resilient means.

' Another object of this invention is to provide an ex: ercising toy having a plurality ofresilient means which cooperatively act and assist each other to impart a safe springing motion while a child is jumping or running.

A further object of this invention is to provide a new and novel jumping shoe which will prevent side sway and twisting motion while in use.

A further object of this invention is to provide a novel and improved jumping shoe of greater resilient capacity by a construction that is inherently capable of allowing the device to compress to a fully collapsed position.

Still a further object of this invention is to provide a novel and improved jumping shoe having primary and secondary springs so arranged that when the primary springs approach full compression, the secondary springs commence functioning to reduce or eliminate the shock of going into a fully collapsed position and to provide great reversing power of the resilient means.

A related object of this invention is to provide a novel and improved jumping shoe having 'a pair of leaf springs which are resilient longitudinally and transversely.

A further related object of this invention is to provide a novel and improved jumping shoe having leaf spring action by a spring structure of wires having a'wave shape.

A further object of this invention is to provide a novel and improved device made in accordance with the foregoing objects and which can easily and readily be attached to and detached from a persons foot.

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

Figure 1 is a perspective view of the first embodiment of the device;

Figure 2 is a side elevational view of the device of Figure 1;

Figure 3 is a side elevational view of the device of Figure 1 when it is under partial compression.

Referring to the drawings and to Figures 1, 2, and 3, in particular, a first embodiment of the device, a base portion is provided having a front section 14 and a rear section 15. A foot engaging portion 11 is superposed with respect to the base portion 10. A foot engaging portion 11 has a toe engaging section 16 and a ice 2 heel engaging section 17. The toe engaging section 16 has a forward part 36 and a front section 14 has a forward part 3-7, the forward parts 36 and 37 are generally aligned and form the forward part of the device. First resilient means 12 and second resilient means 13 are provided. The first resilient means has a primary spring 18. The primary spring 18 is composed of a pair of leaf springs 28 and 128', which are in operative connection with each other and form a V configuration coming to apoint29.

Second resilient means 13 is of like construction and hasprimary spring 19. Primary spring 19 is composed of a pair of leaf springs 228and' 328 inoperative con nection witheach other in aV-shaped configuration coming to a point 129. j 1 e The primary spring 18 has a first end'24 which is carried by the toe engaging portion 16 at 30, and a second end 25 which is carried by the front section 14 at 31. An upper secondary spring 20 of the first resilientmeans 12 is provided and carried by the primary spring 18 at'30. The spring 20 is positioned between the toe engaging section 16 and the primary spring 18. A lowersecondary spring 21 is carried by the primary spring 18- at '3 1.'The lower spring 21 is positioned between the front section 14 and the primary spring 18. g

The primary spring 19 has a first end 26 which is carried by the heel engaging section 17 at 32. The primary spring 19 has a second end 25 which is carried by the rear section 15 at 33. Second resilient means 13 has an upper second spring 22 which is carried by the'prim'ary spring 19 at 32. The upper secondary spring 22 is posi-. tioned between the heel engaging section 17 and the primary spring 19. Second resilient means 13 has a lower secondary spring 23 which is carried by the primary spring 19 at 3-3. The lower secondary spring 23 is positioned between the rear section 15 and the primary spring 19. All of the secondary springs 20, 21, 22, and 23 are shorter than any of the leaves of the primary springs 18, and 19.

The point of the Vs 29, and 129, are in a plane between the base portion 10 and the foot engaging portion 11 and parallel thereto. The points 29 and 129 of the primary springs 18 and 19, respectively, pointin the direction designated as the forward part of the device. The toe engaging section 16 has a buckle strap 34 to hold the front portion of a human foot. The heel engaging section 17 has a heel stop 35 and a buckle strap to hold the heel portion of a human foot. l

A person attaches the device to his foot by the foot engaging straps 34 and 135. As he stands on the device, the device partially depresses and the leaves 28 and 128 of the primary spring 18 approach'each other. Also, the leaves 228 and 328 of the primary spring 19 approach each other. If a person bounces down heavily on the device, the springs leaves 28, 128, 228, and 3-28 approach each other more closely and the secondary springs 20, 21, 22, and 23 abut against their respective primary springs 18 and 19, and give an added amount of resiliency. If a person instead of bouncing straight down on the device rocks forward, the leaves 28 and 128 of the primary spring 18 approach each other and the leaves 228 and 328 of the primary spring 19 spread apart. The reverse of this happens if the person rocks backward. Because of this construction, it is possible to have a front and backward rocking motion.

Also, because of the provision of two primary springs and their configuration and placement the one will tend to have a negative compression when the Weight is distributed heavily on the other, and no constraining means is needed to limit their movement. When a person runs on this device, because of the arrangement of the primary springs 18 and 19, the cooperative resilient action reinforces the natural running motion and cooperates with it in order to provide an increased thrust of force. Inherent in this natural cooperation is the prevention of side sway or twisting which makes this device safe to use and reduces the possibilityof injury to. the user.

Although the invention has been described in-its preferred form with a certain degree of particularity, it is understood that the present disclosure of the preferred form 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 the scope of the invention as hereinafter claimed.
