Abstract:
A rocking toy has an animal-shaped body supported by a tubular framework. The framework has a fore and a hind frame portion. The hind frame is rightly supported on a base. A resilient member is placed between the fore and the hind portion, allowing a limited movement that simulates a horse rearing on its hind legs.

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     This invention relates to toys for children and more specifically to rocking toys such as rocking horses. 
     2. Description of the Related Art 
     In one type of rocking horses, a seat is supported by a convex shaped base in contact with the floor. Forward and back motion of a child&#39;s body simulating a ride on horseback causes the convex base (and hence the seat) to rock about an axis of rotation passing through points of contact betweeen the convex base and the floor. 
     In another familiar implementation, the rocking horse is mounted on a stationary base in a manner which allows the horse to rock about a horizontal axis of rotation centrally located within the rocking horse at a certain height from the floor. The rocking motion is initiated by the shifting of the weight of the child. 
     For example, U.S. Pat. No. 3,138,376 to Ryan relates to a rocking horse with an elevated axis of rotation. The horse&#39;s body is supported by an integral upright and a yoke extending upwardly from the upright. A transverse pin forms an axis of rotation about which the horse rotates. A link has a horizontal pivot mounting at one end at a selected elevation on the upright. 
     Another design described in U.S. Pat. No. 2,968,483 to Dodson relates to a rocking horse with a rocker arm and a seat member. A rear spring reciprocates the motion of the rocker arm with respect to the seat member. A front spring reciprocates the motion between the rocker arm and a floor support. 
     The motions provided by these prior designs have not been very realistic. It is an object of this invention to provide a more satisfying toy by allowing the child to ride the horse &#34;lone ranger&#34; style with the horse rearing on its hind legs. It is a further object to provide a toy which can move more realistically, simulating the movement of a horse in gallop or in a steeple chase. 
     SUMMARY OF THE INVENTION 
     In the illustrated embodiment, the rocking toy of this invention has a padded animal-shaped body supported by a framework. The framework has two articulated sections, a hind frame section and a fore frame section, that can move with respect to each other in a limited fashion. A resilient member, such as a gas-filled cylinder with a piston therein, is placed with one end on the fore frame and the other end on the hind frame. The cylinder stores the energy of a downward motion of the fore frame by compression. The energy is then released to aid the upward motion of the fore frame. 
     In another aspect of the invention, the hind frame which is secured at one end of a support base forms part of the rear legs of the animal while the front frame forms a part of the front legs. 
     The invention will be more clearly understood from the following description of a preferred embodiment with reference to the accompanying drawings.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     The following description is of the best presently contemplated mode of carrying out this invention. This description is made for the purpose of illustrating the general principles of the invention and should not be taken in a limiting sense. The scope of the invention is best determined by reference to the appended claims. 
     Referring to FIG. 1, a rocking toy in accordance with a preferred embodiment of the present invention is indicated generally at 1. The exterior body of the rocking toy 1 can be manufactured of a flexible resilient material in a padded shaggy animal shape, such as a horse as shown. It is recognized that other shapes, including those of other animals, may be used. 
     An inner framework 2 of the rocking toy 1 includes a fore frame portion 3 (see also FIG. 2) and a hind frame portion 4 which are formed of tubular parallel side members 3a and 3b, 4a and 4b, respectively. The fore side members 3a and 3b and the hind side members 4a and 4b are bent to fit and support the horse&#39;s exterior body, especially at the legs. As will be described in greater detail below, the fore and hind frame portions 3 and 4 pivotally and resiliently coupled together in a manner which permits a rearing-type rocking motion. 
     The fore side members 3a and 3b are connected to each other by two cross members 5 and 6. Cross member 5 is joined to a head support frame portion 7 which bends upwards, toward the head of the horse. The frame portion 7 is further joined to a T-shaped tubular member 8, on which handles 8a, 8b are mounted for a child to hold on. 
     The hind side members 4a and 4b are connected to each other by a cross member 9. The side members 4a and 4b are attached to a support base 10 by upright shanks 11a and 11b, integral with the base 10. The shanks 11a and 11b are inserted into the hind side members 4a and 4b and are locked in place by locking bolts 12a and 12b. The support base 10 is illustrated as a rectangular frame but may have other shapes as well. 
     The fore portion 3 is pivotally connected to the hind portion 4 of the framework 2 by a pin 13 passing through coaxial holes formed into connecting plates 3c and 3d integral with the back ends of the side members 3a and 3b, respectively, and connecting plates 4c and 4d integral with the fore ends of the side members 4a and 4b, respectively. The pin 13 is provided with threaded ends. The pin 13 connecting the plates 3c and 4c of the side members 3a and 4a and the plates 3d and 4d of the side members 3b and 4b is secured in place by spacers abutting members 15a and 15b and nuts 14a and 14b screwed at the threaded ends of pin 13. In this manner the fore portion 3 of framework 2 can pivot up and down with respect to the hind portion 4. 
     Bored connection plates 17a and 17b extend side-by-side from the hind cross member 9. Another pair of connection plates 16a and 16b are directed essentially downwards and are attached side-by-side to the cross member 5 of the fore portion 3 of the framework 2. A so-called &#34;gas pump&#34; type resilient device 18 is pivotally connected at opposite ends to said connection plates 16a, 16b, 17a and 17b by means of threaded bolts and nuts 16c, 16d, 17c and 17d, respectively. Such &#34;pump&#34; device 18 includes a pneumatic cylinder 19 in which a piston is sealingly received. A high pressure gas is contained within the cylinder 19 so that the inner surface of the piston is subjected to the pressure of the gas and the outer surface thereof is at atmospheric pressure. A free bored end 22 of a piston rod 20 is pivotally connected to the connection plates 17a and 17b of the hind portion 4 of the framework 2 by means of the above-mentioned bolt and nut 17c and 17d. The opposite end of the cylinder 19 is also pivotally connected to the connection plates 16a and 16b integral with the cross member 5 of the fore portion 3 of the framework 2 by means of bolt and nut 16c and 16d engaging a pivot pin 23. 
     The operation of the assembly would not change substantially if the position of the gas pump was to be reversed. 
     The gas pump device 18 varies in length as pressure is applied, allowing the fore portion 3 of the framework 2 to rotate downward as a load is applied thereon, i.e. when a child sits on the back and moves his body forward. The gas pump 18 operates as a spring resisting the lowering of the fore portion of the rocking horse. As the fore portion lowers, energy is stored in the gas pump device 18, until the latter reaches maximum compression at which point the pump device resisting force equals the downward force, preventing further lowering of the fore portion. Energy is then released as the child moves his body back and the fore portion of the rocking horse stands up again. A bent plate 21 is provided for protecting the gas pump mechanism. Of course, the padding and the shaggy horse-shaped covering are flexible, thus conforming to the motion of the fore portion of the rocking horse. 
     While the invention has been described with respect to a preferred embodiment, it will be apparent to one skilled in the art that other modifications can be made without departing from the spirit or scope of the present invention as defined and claimed herein.
