6 Claims.

for its principal object the provision of an animal-simulating toy which is susceptible of voliticnal actuation to produce leaping or jumping movements thereof. Y

Another object of the invention is to provide an effective actuating mechanism for such a toy, whereby a lifelike leap clear of the supporting surface may be imparted to it with a minimum of effort, well within the capability of a relatively small child. Furthermore, the construction is such as to tend to prevent tipping over of the toy, either at the beginning or at the conclusion of the movement.

While for purposes of disclosure of the principles of the invention a frog has been chosen for illustration in the accompanying drawing forming a part of this specification, the genus of the animal simulated is not important and the body form may be that of any appropriate member of the animal kingdom.

In the said drawing, in which like reference characters designate llike parts in all the views- Figure 1 is a side elevational view'of a toy constructed and arranged in accordance with the invention;

Fig. 2 is a bottom plan view, partly broken away and in section, of the toy shown in Fig. 1;

Fig. 3 is a longitudinal Vertical sectional viewof the toy, with the parts ybeing shown in the positions they normally occupy when the toy is at rest upon a supporting surface;

Fig. 4 is a view similar to Fig. 3, showing the parts in the positions assumed inthe course vof a'leap;

Fig. 5 is an enlarged side elevational view of the lower portion of the actuating cylinder and the parts associated therewith and Fig. 6 is an end View of the parts shown in Fig. 5.

Referring to the drawing in greater detail, the toy there shown comprises a hollow body I having the general conformation and external mark- Y ings of the animal simulated, in this case a frog.

.edly .attached as at I3 the rearward Vend. of an element I4 simulating the lower or tibial portion of a hind leg. As will be clear from Fig. l, the tibial elements I4 normally underlie the femoral elements I2, in engagement with the supporting surface, and the forward ends I5 of the elements I4, which are formed to simulate the hind feet, are disposed adjacent the mid portion of the body.

The several leg elements II, I2 and I4, along with the body I0, may conveniently be constructed of soft rubber or appropriate molded plastic material. `While for the purpose of facilitating manufacture the fore leg elements II and the femoral elements I2 may be formed as members separate from the body, to which they are subsequently cemented 0r otherwise xedly attached,

if convenient the members I0, II and I2 may be molded as an integral unit. When the parts are of soft rubber or like yieldable material, thehinging action between the upper and lower hind leg elements I 2 and I4 may be secured solely through exing or stretching of the material at or adjacent the points I3.

To the lower face of the foot portion I5 of each tibial element I4 there is cemented a pad I6 of sponge rubber or the like. The under faces of these pads frictionally engage the ground or other supporting surface I8 and provide an anti-slipping contact therewith which is of material assistance in securing the desired leaping action through the air, completely clear of the supporting surface. The foot portions I5 are of reduced thickness or otherwise formed to provide ilexibility at I1 along a transverse plane coincident with the rearward edge of the pads I6, whereby a hinging action may take place at this point which permits the pads to remain in at contact with the surface I3 during the initial portion of -a leap and tends to prevent the toy from nosing over forwardly. In some cases the entire tibial elements I4 may be formed of sponge rubber, in which event separate pads I 6 of such material of course need not be used.

Within the cavity or chamber I9 dened by the walls of the body I0 there is mounted a fluid pressure cylinder 20. As will be readily understood from the drawing, the axis of this cylinder is disposed in substantially the plane of the longitudinal axis of the animal and at an inclination of approximately 30 to the vertical when viewed as in Figs. 3 and 4; and the upper end of the cylinder, which is closed, is provided with a port ed boss 2| to which is connec;ed one end'of a flexible tubing 22 which extends through the wall of the body I0 and has its other endV connected to a resilient bulb or equivalent manually operable uid pressure inducing device 22'. The cylinder 2|) is supported within the cavity I9 by means of a transversely extending member 23, conveniently comprising a curved wire, the mid portion of which is soldered, welded or otherwise rigidly attached to the cylinder at 24. The lateral portions of the member 23 extend from the cylinder across the cavity I9 to and interiorly of the fore leg elements Il, in which they may be embedded or otherwise attached. The curved wire` 23, while rigid enough to provide supportfor the cylinder 2B, is at the same time suliiciently yielding to provide a cushioningaction in the fore legs when the toy lands at the conclii'sinof-a Yleap; The said wire also serves to transmit the impelling force to the body, as willpresently-appear.

Mounted in the cylinder 20 is a piston structure 26, carried by one end of a pistonlr'odfZI which is slidably received in a bearing sleeve 2-8 supported at the `open lower end ofthe cylinder bythe crossed Ueshaped wires 29, thev cross bars of which are soldered or welded to the sleeve while their legs are soldered orwelded to the exterior ofthe cylinder wall, as will be clea1` from Figs. and 6.` A helical compression spring 3Q is inL terposed between the pistonzlt and the grid wires 29, and tends to maintain the parts in the posi'- tie'iis" shown in Fig. 3,1 with the-piston in the upper end of the cylinder. Below the bearing sleeve 28 the piston rod 2l'` extends through an aperture 3| formed' in the lower wallv of the body I0, and the lower end of said rod is provided with a' transverse hole whichjournals the mid'portion of a transverse wire 32 extending .beneath the body l@ to' the forward parts ot thehindfoot portions IEIand anti-slippingpads I6 to which the wiieehds are attached.

Theoperation of the toy as thus -far described Will be readily llhd'elstod. With the Simulated animal resting upon the groundoi' otherv supe porting/surface -l 3 as shown in Fig. l, upon manu*- ally squeezing the bulb 22 the 'fluid therein will be compressed and forced through the tube 22 to the upper end vofk the cylinder 2D', above-the `pis- ,.n

ton 26. With the antieslipping, members IBJn engagementwith the'surface I8 and` through the' transverse connecting memberY serving as thrust-taking members or anchorsV for theapiston rod `2l and piston 26 to restrain `movement Tf,

thereof, the increased pressure in the. cylinder above the piston causes axial movementvof the cylinder upwardly and forwardly, which :motion is transmitted Vthrough the supporting. wireor member 23 to the 4body le. Asa result the body is propelled upwardly and forwardly,.with the relative movement between the cylinder` and piston causing the hind leg elements I .to assume the position shown in Figa, at. which time the momentum is such as to cause the entire toy lto 4 time, there Still is substantially no tipping tenda ency. If the bulb be pressed quite slowly so that the build-up of pressure in the cylinder is relatively slow, the hind leg elements I4 may be actuated to the Fig. 4 position without the toy acquiring suihcient momentum to leave the surface I8, and as a result it will merely inch along such surface. Y

The widespread fore legs II,YeXtending well forwardly of the center of gravity, coupled with the fact that the propulsive force is applied to Ythe body in a direction more upwardly than forisy bodily leave the supporting surfaceand followva trajectory which carries it forwardly a footvor more from the starting point infclosesimulation of the leap of a real animal.

Ordinarily the manual pressure iseXerted on the bulb 22 only fmome'ntarily, i..e. the bulb is given aquick squeeze and released, and .upon such release .the :fluid pressurein the' cylinder ZI) .above thepsto'n Z'Sialls tonormalandthe spring `30 returns the parts .to ,theV Fig'. 3': positions by the time theleap is completed. 'A landing under such conditions is effected withzpractically;no

tendency ofthe toy to -tip over; and even if the .bulb is notreleased prior tolandi11g. softhatiithe hind leg velements :I 4 .are -stillv ;extendedat; v.such

wardly, tend to prevent the animal from tipping orfno'sing ovenforwardly whenV the bulb is pressed; andjsincethpai'tsj are so arranged that the centei of g'ravity'lies'-substantially in the plane of Hthelongitudinalfaxis of the toy, and since the propulsive force is applied to the body symmetrically on opposite sides of said plane, there is substantially no tendency of the toy to tip sidewise.

Toys constructed` asiabovie described will Vfunction quite satisfactorily' tolgive life-like .leapsof a footv or more, depending upon the size and weight ofrtheparts. However, theflength of the leap may be materially increasedzby the useof an action delaying device -i'n conjunction with the cylinderfand piston, and onezformfof -such arrdee vicer has; been illustrated in :the present drawing- As here shown, it comprises a U-shapedwire member' disposed at" the lowery end of the Vvcyli inder 2G, with the extremities of its legs soldered or welded asV at36` tothe` cylinderwall, and lits crossbar extending across the .open end of `the cylinder in position to engage a small-'arc off the end V,edge of the piston rod2l when the latter is inthe' position shown in'Figs. 3, 5fand 6. .The restraint thus imposed uponmovement of the cylinder 2),'relativ'eato:thel rodA 21and lpiston. 26 enables thefbuilding up of :some-.pressure `above the piston inV addition to that necessary .to.over' come the action of the .springrSIL and when the desired Abuild-up has been atta-ined the resilience of'. the legs ofv the latchY member-35 permits` the cross bar ofV such member @to be forced upwardly out ofzleng'agement with the .edge ofv :the rodveiid, whereupon the cylinder will ascend with,r some-y thing .of a snap action. As 'above indicated; lthis will -.material1y increase' the 4length of theleap.

In the case of some animals the cylinder-supporting and iforceetra'nsmitting VV'member 2 3 may be attached directly to the. wallsof thebo'dyfadxjacent the cylinder, insteadf .of extendinginto and .being secured tofithefore legs; and if thebody cavity I9 is small 4.enough forsthe -body wallsto directly engage and support the cylinder, `the member 23 `r'nayzbe dispensed v'with for this ,pur-

DOSE.
