Patented Dec. 12, 1950 UNITED STATES PATENT OFFICE TOY SWING Charles E. Liesner, Detroit, Mich, assignor to Benseil Corporation, Detroit, Mich.

4 Claims.

This invention relates to a toy swing, and more particularly to a swing mounted to maintain a horizontal position throughout its reciprocal swinging arc.

It is the object of this invention to provide a toy swing having a pair of spaced pivotally mounted levers, with the swing suitably suspended from the upper free ends of said levers.

It is the object of this invention to provide a plurality of seats on the swing, and with the upper ends of said levers having handle bars projecting therethrough and with their lower ends having foot rests projecting therefrom.

It is the further object of this invention to provide a swing construction wherein the rider or riders may actuate said swing by manually pivoting one or both of said levers by pumping with the feet on said foot rests and at the same time pulling upon the handle bars.

These and other objects will be seen from the following specification and claims in conjunction with the appended drawing in which:

Figure 1 is a perspective view of the toy swing.

Figure 2 is an enlarged fragmentary plan view thereof.

Figure 3 is a fragmentary side elevational view thereof.

Fi ure 4 i an elevational section on line 4-4 of Figure 3.

Figure 5 is a section on line 5-5 of Figure 4; and

Figure 6 is an elevational section on line 66 of Figure 3.

It will be understood that the above drawing illustrates merely one preferable embodiment of the invention, and that other embodiments of the invention are contemplated within the scope of the claims hereafter set out.

Referring to the drawing, the swing consists of a pair of spaced longitudinally arranged supports H whose ends are maintained in spaced relation by the spacer blocks [2 interposed therebetween.

Rivets I 3 project through the respective ends of members II and through corresponding openings in said spacer blocks to securely retain said members with respect to each other.

Formed end seats 14 are mounted upon the ends of upright members H and spacers l2 and secured thereto by screws l5. Central formed seat It is centrally mounted astride members H and secured thereto by screws IT.

A pair of spaced levers l8, suitably joined at their upper ends to spaced ropes or chains l9, are pivotally joined to supports II at points intermediate the ends of said levers.

As shown in Figures 4 and 5 the shank portion of each lever is centrally positioned within hollow trunnion members 20, and immovably retained therein by the transverse pins 2| and retaining cotter pins 22, said former pins extending through the body of said trunnions as well as through said levers.

Trunnion members 20 have a pair of oppositely projecting supports or bearing members 23 which extend rotatively into bushings 24 mounted within corresponding openings formed in supports I I. Consequently levers l8 and the spaced trunnions iii! are pivotally mounted upon and between supports II.

In the present preferable embodiment of the invention, members H are constructed of wood, consequently brass bushings 24 provide a sturdy bearing support for trunnions 20 and prevent wear to said supports.

As shown in Figure 4 handle bar shaft 25 projects snugly through a transverse opening in the upper portion of lever l8 and is immovably secured therein. Hand grips 26 are positioned upon opposite ends of said handle bar and are suitably secured thereon.

Foot rest shaft 21 projects snugly through a transverse opening near the lower end of lever i8 and has rubber or other foot rest 28 mounted thereon. Additional spaced transverse openings 29 and 30 are provided at the lower end of lever I 8 above the foot rest shown in the drawing whereby said foot rest bar 21 may be elevated if desired to accommodate the user's legs.

Riders on seats I 4 manually grip handles 26 while their feet bear against foot rests 28. Thus, with the riders pulling and pushing in unison upon levers l8, it is possible to effect swinging movement of the toy without a push from any outside source, and with the swing supports ll maintained at all times in a horizontal position A third rider can be accommodated on the central seat It; or on the other hand a single rider on seat It may p vota ly actuate either of the levers IE to swing himself.

As shown in Figure 4 in the preferable embodiment of the invention, a stirrup 3| is secured to the upper end of the lever l8 by suitable rivets 32. Said stirrups have loops 33 upon their top portions to receive the lower ends of ropes or chains l9. Figure 4 shows hook members 34 upon the lower ends of ropes l9 adapted for-attachment to the loops 33 on said levers. It is contemplated however, that any other form of attachment may be employed if desired.

The upper ends of ropes or chains l9 are sultably suspended from any horizontal support such as the beam 35 shown in Figure 1, which could be the limb of a tree or any other substantially horizontal support.

Figure 3 illustrates in dotted lines several angular positions of levers 18 which they assume in the operation of the swing. In view of the parallelogram support of the swing it is understood that said swing will at all times remain in a horizontal position throughout its reciprocal swinging arc.

While the drawing illustrates ropes 19 as the means of support for the swing, it is contemplated that any other form of longitudinally spaced supports could be provided, such as chains or rods. Consequently while applicants claims may specify a pair of longitudinally spaced supporting ropes, it is understood that it is intended to include equivalent supporting structures, the upper ends of which are pivotally or swingably suspended from a suitable support, and with its lower free ends suitably joined to the levers forming a part of the swing.

Having described my invention, reference should now be had to the claims which follow for determining the scope thereof.

I claim:

1. A swing comprising a pair of longitudinally spaced ropes, a pair of spaced horizontally arranged supports secured to each other, a pair of spaced trunnions interposed between said supports and pivotally and supportably mounted therein, and a pair of longitudinally spaced upright levers pivotally connected at their upper ends to the free ends of said ropes, and with their central portions projected down through and secured within the central portions of said trunnions, whereby said levers are pivotally joined to said supports.

2. A swing comprising a pair of longitudinally spaced ropes, a pair of spaced horizontally arranged supports secured to each other, a pair of spaced bushings mounted Within and towards each end of said supports, a pair of spaced trunnions interposed between said supports and pivotally and supportably mounted within said bushings, and a pair of longitudinally spaced upright levers pivotally connected at their upper ends to the free ends of said ropes, and with their central portions projected down through and secured within the central portions of said trunnions.

3. A swing comprising a pair of horizontally spaced ropes, which extend from a suitable support, a pair of spaced horizontally arranged supports secured to each other, a pair of spaced trunnions interposed between said supports with their oppositely extending end portions pivotally and supportably mounted therein, a pair of longitudinally spaced upright levers pivotally connected at their upper ends to the free ends of said ropes, and with their central portions projected within and secured to the central portions of said trunnions, and oppositely arranged seats secured at the outer ends of said spaced supports.

4. A swing comprising a pair of horizontally spaced swingable ropes, a pair of spaced horizontally arranged supports secured to each other, a pair of spaced trunnions interposed between said supports with their oppositely extending end portions pivotally and supportably mounted therein respectively, a pair of longitudinally spaced upright levers pivotally connected at their upper ends to the lower free ends of said ropes, and with their central portions projected within and through the central portions of said trunnions, means for retaining said levers within said trunnions, seats mounted at the opposite ends of said supports, and a third seat centrally mounted upon said supports.
