Wyman Company,

The present invention relates in general to spring mounted riding devices such as to-y hobby horses, jumping chairs or seats and other devices of a similar character wherein therider may obtain a rocking or forward and backward oscillatory motion along with a bouncing movement to either simulate-the actual motion of alive animal or obtain exercise beneficial to physical development. Such devices are used almost exclusively by small children or physically undeveloped persons, and in the past, harmiul mishaps have occurred by reason of the prior art devices of this nature being either laterally unstable or uncontrollable by the person riding them.

Another shortcoming of the devices available in the prior ant is the fact that the seat portion is usually sur rounded by a complicated frame or suspension structure, ofttirncs involving'upright post members and-even moving hinged parts located in a position where bodily injury might result to the rider in case of a fall.

it is contemplated that the present invention will elimimate the possibility of bodily injury to the rider -by presenting a sturdily but simply constructed base portion dispensing with material obstructions in the'area immediately surrounding the riding device, while at the same time providing fora greater degree of control and safety for the rider.

This invention thus has for its primary object the presentation of novel and useful improvements in spring suspended riding devices such as toy animals, jumping chairs, seats, or other controlled spring suspension de vices.

Another object of the present invention is to provide a device completely spring suspended and capable of backward and forward oscillatory rocking motion freefrom jlateral tilting.

A funther object of this invention is the provision of a riding device completely spring suspended and capable or backward and forward oscillatory rocking motion which is free from lateral tilting while allowing for er i a bouncing mo i n to s mula e h nsat on f ding a l anima A, i th bi of his n enti i t presen an impr ed co tr l d s ng s pens o un t h h is o pact, novel and eiiicient and of ,Such a character to be capabl o mo nt ng thin he t y animal or riding seat to be concealed thereby.

A still further object of a modified form of this invention is to provide ,a spring suspended device of .the type characterized wherein the rider is able to pivot the rocking device to turn it to face in any desired direction wh le rid g- Ilhe rneans by which the foregoing objects and other advantages, whi h will be apparent to those skilled in the art, ;are accomplishedare set forth in the following specification and claims and are illustrated in the accompanying drawings .dealing with the preferred-embodiment and several modificationsthereof.

FIG. 10 is a sideelevation view of a modified construction .of the base supporting unit suitable for use with the form of the device'wherein the spring suspension unit is located within the body portion of the riding device.

Referring now to the drawings, wherein like reference numerals are used to indicate identical parts in the various views, the preferred embodiment of the present invention, shown in FIGS. 1 to 4, comprises a body 1 preferably in the form of any of the well known types of toy hobby horses including a saddle or seat member 2 upon which the rider sitsand handgripping devices extending laterally beyond both sides of the horses head, one of which is illustrated at 3, FIGURE 1. The body 1 is supported upon base assembly 4 by a controlled spring suspension unit presently to be described. The base assembly 4 is made up of longitudinally extending tubular leg members 5 which have bent up vertical portions extending into the body of the hobby horse from the bottom side nd laterally extending short tubular members 6 having vertically extending bent up portions which extend as far as the clamp 7 which is used to clamp the four tubular ,leg'membjers together in a well known manner. The controlled spring suspension unit which rockably supports the body 1 upon the base assembly and legs formed'in the bottom of the body 1, said cavity 10 being designed to receive, contain, and conceal the entire controlled spring suspension unit. The attaching frame assembly 8 is made up of the separate identical side members ,11 and 12 and the attaching bolts '13 and 14 which join the adjacent front and rear end portions of the side members through appropriate parallel tab portions 15 and 16 respectively of the. side members 12 and 11. Rigidly bolted to upstanding leg members 5 by bolt means 17 is a spring anchoring strap 18 formed of two identical side members which terminate in rearardly extending bifurcated jaw members 19 and .29 and in a forwardly extending watered anchoring bracket 21, 2210 which is attached a helical tension spring 23 having a hooked end .24 passing through the hole 25 in the anchoring bracket. The forward end of the spring 23 is attached to the bolt 13 of the frame 8 by means of a hook 125 formed on the forward end of the spring. A rear helical tension spring 27 is mounted between the bolt 1-:- of the attaching frame 8 and a bolt 28 extending between the jaws l? and 2b of the anchoring strap. As clearly shown in FIGURES 2 to 4, the helical springs 23 and 27 are disposed in the same horizontal plane and are in substantial alignment when the horse body is in its unactuated condition, i.e., no substantial load being supported by the tension springs. Upon actuation of the horse body, the springs move out of alignment as illustrated by the dotted line positions in FIGURE 3. Surrounding the rear helical tension spring is a telescoping guide means composed of outside tube member 2% pivoted on the bolt 14 and extending between the spaced tab members 15 and i6 and a forward internal tube member 3d pivoted on the bolt 23 and extending betwen the jaw members 19 and 2d of the anchoring strap. As seen most clearly in FIGURE 4, the telescoping members 2? and 3d are rectangular in cross section and provide a snugly fitting telescopic unit which is prevented frorn pivoting about a longitudinal horizontal axis by virtue of the two point contact of both of its members with the respective horizontally rigid pivot bolts 14 and 2b. In actual practice, it is not contemplated that any lubrication between the sliding portions of the telescoping guide unit will be necessary, but if such does become desirable, a form of lubricant such as graphite which will not tend to drain from the sliding surfaces may be used.

In FIGS. 5 and 6 a somewhat modified form of the attaching frame means shown in FIGURES 2 to 4 is illustrated wherein the side frame members 11 and 12 of FIGURE 2 are eliminated and the horizontally disposed rigid transverse pivot rods 13 and 14 extend cmpletely across the cavity 1i and are anchored in the walls of the body 1 and retained therein by any suitable means such as cotter pins 31. The anchor strap 18' of FIGS. and 6 differs from the strap 18 of FIGS. 2 to 4 in that its side members 32 and 33 are unconnected narrow metal bands welded directly to the upright leg members 5 and have parallel transversely spaced forward arms 34 and transversely spaced diverging rear arms 35 with parallel end portions to receive the horizontal transverse pivot bolt 28 of the telescoping unit described in the preferred embodiment. The forward arms 34 of the bands 32 and 33 receive the horizontal transverse bolt 36 to which is attached the hook member 24 of the tension spring 23, the other end of said spring having a hook portion 26 attached to the transverse rod 13. The telescoping guide unit 29, 30 along with its horizontal transverse pivot bolt 28 and the enclosed rear tension spring 27 is identical to that shown in FIGS. 2 to, 4, the rear section 2? being pivoted on the horizontal transverse pivot rod id similar to the pivot bolt 14 of FIGS. 2 to 4. It will also be noted that the helical tension springs of the embodiment of FIGURES 5 and 6 are disposed in a horizontal plane and are in substantial axial alignment as described in connection with the embodiment of FIGURES 2 to 4, when the device is in its unactuated condition.

in the above described preferred embodiment and the modification thereof, the youthful rider mounts the seat or saddle 2 of the hobby horse, grasps the hand grips 3 and by alternately throwing his body weight forwardly and rearwardly, causes the hobby horse body to rock forwardly and rearwardly in response to his motions and by reason of the spring suspension between the hobby horse body and the anchoring strap carried by the upright leg members obtains a compound bouncing and fore-to-aft oscillatory rocking motion, The action of the telescoping guide unit 29, 3t) and the front and rear springs 23 and 27 respectively, is illustrated in FIGS. 3 and 5 which show the double pivoting and telescoping action of the guide unit both during rearward and forward tilting. The body unit, however, is prevented from tilting or listing to either side by virtue of the rectangular cross section of the telescoping unitand the two point pivotal contact with the horizontal, rigid transverse pivots.

FIGS. 7 to 9 show a further embodiment of the spring suspension mechanism according to the present invention wherein the body of the riding device is indicated generally by the numeral 37, said body including a central solid portion 33 with a cut-out portion suitable for receiving the spring suspension unit. Said body also has side members 3? and 4,6 which ext-end downwardly below the central portion to conceal the suspension unit and to provide a rigid mounting therefor. An upright post member 41 is designed to support the suspension unit and the riding device and may be in turn supported by any suitable and stable base structure. Mounted on the upper end of the post 41 appears a U-shaped support member 42 having the end portions of its legs connected by brace member 43. A symmetrical support frame comprising identical sections 44 and 45, rigidly fastened to the body side members by bolts 46 and connected by a centrally located inverted U-shaped guide loop 47, is best illustrated in FIGS. 8 and 9. The supporting frame is disposed in a horizontal plane and guide loop 47 straddles the cross brace 43 to allow for relative movement between the loop 47 and the brace 43. Forwardly and rearwardly disposed control springs 48 and 49 respectively are connected between the front end and the rear end of the supporting frame and the legs of the U- shaped support 42 by means of adjustable eye bolts 56 and 51 and appropriate loops 52 carried by the member 42. The springs 48 and 49 are seen to be in sub stantial alignment and are disposed in the same horizontal plane as the supporting frame members 44 and 45, when the device is in its unactuated condition as shown by the solid line portions in FIGURE 7. The pivoting action of the modified spring suspension is similar to that described in the preferred embodiment and is shown by the broken line portions of FIGURE 7 with the inverted U-shaped guide loop 47 coacting with the brace 43 which passes therethrough to prevent lateral tilting or listing during the rocking motion.

FIGURE 10 illustrates a still further modification of the base or supporting structure suitable for use with any one of the described spring suspension units which are located within the body of the hobby horse. The base coacts with the spring suspension device of the present invention to permit the rider to pivot the rocking device to face in any desired direction while riding. Only the essential details of the base construction will be described in connection with FIGURE 10, since any form of spring suspended rocking device having a body 71 and a vertically extending pedestal 72, preferably in form of cylindrical tube, may be mounted in the novel base structure. The base structure itself comprises a vertical tube 73, having the bottom end thereof closed by plate 74, which acts as a bearing and support for the pedestal 72 rotatably mounted therein. The tubular bearing 73 may be supported in its vertical position by means of legs 75 welded or attached thereto by any suitable means. The legs extend radially outwardly from the tube and are inclined downwardly to the supporting surface of the floor. The tubular bearing 73 terminates short of the supporting surface and has brace members 76 connected to its bottom plate by bolts 77. Said braces 76 extending radially outwardly from the tube and are rigidly connected to the legs 75 to thereby form a truss structure. The legs 75 are held in their predetermined radial positions by means of a preformed bracing plate 78 surrounding the tubular bearing 73 and secured to the legs by bolts 79.

In operation the rider may cause the entire hobby horse body 71 to pivot in a horizontal plane in either direction within a 360 are by throwing hi's bod'yi'weight slightly to one side or the' other ashe rocks forwardly or rearwardly. The turning movement of the hobby horse body will be in small increments accompanying each fore 'or aft rocking motion, by virtue of the side thrust imparted to the body 71 as the riders'weight is thrown forwardly or rearwardly past adead cente'r position and to one side thereof. It will be understood, however, that no s'idew'ise tilting or listing. of the-hobby horse body will accompany the turningmovement since such is prevented by the novel telescoping spring guide unit previously described. Hence, the turning motto-n of the hobby horse body will not tend to unbalance the rider andunseat him from the saddle portion. It will also be noted that the foregoing body control by therider will further enhance the value of the rocking deviceas ameans to practice muscular coordination of the physically undeveloped rider.

It will be readily apparent to those skilled in the art that the present invention provides a novel and useful improvement in controlled spring suspension units for riding devices of the character described. The arrange ment and types of structural components utilized within this invention may be subject to numerous modifications well within the purview of this inventor who intends only to be limited to a liberal interpretation of the specification and appended claims.
