Pinkham Assistant ExaminerR. T. Stouffer Attorney, Agent, or Firm-Howard I. Podell [5 7] ABSTRACT A rolling balancer formed of two wheels connected together by an axle to which a U-shaped bar is attached perpendicular to the axle. The bar extends horizontally beyond the wheels and is bent at each end to form vertical handle members which are grasped by the user standing on the bar and balancing himself on the device.


This invention relates-to a'rolling balancer formedof a pair of wheels joined by an axle to which a U-shaped bar is attached. The wheels rotate independently of the axle and of each other, and vertical handle members rise from each end of the horizontal ends of the bar.

The advantage of this invention is that it provides a source of amusement and physical exercise for youngsters, and helps to develop the users sense of balance.

A further advantage of this invention is that its of simple design and readily constructed.

The invention comprises a pair of wheels, connected by an axle, that turn independently of the axle and independently of each other. A horizontal bar is connected to the axle perpendicular to the axle and located midway between both wheels. The bar extends horizontally beyond the wheels in both directions and a vertical handle member is joined to each end of the bar. Foot pads are attached to the upper surface of the bar on each side of the axle.


The objects and features of the invention may be understood with reference to the following detailed description of an illustrative embodiment'of the invention, taken together with the accompanying drawings in which:

FIG. 1 is a perspective view of the balancer bar device;

FIG. 2 is a top view of the device;

FIG. 3 is a side view of the device; and

FIG. 4 is a front view of the device.


Turning now descriptively to the drawings, in which similar reference characters denote similar elements throughout the several views, FIG. 1 illustrates the balancer bar toy being used by a youngster 12. The toy 10 is formed of a set of wheels 14 each rotatably attached to an axle 16, with a hollow bar 18 attached to the mid-point of the axle 16. Vertical handles 20 are attached at each end of the horizontal section of the bar 18.

As shown in FIGS. 2-3, the bar 18 is attached by means of screws 22 through a rectangular portion 24 of the'bar 18 that is wider than the diameter of the axle 16 and is located so that each pair of screws 22 lies on a different side of the axle 16. The screws 22 go through the rectangular portion 24 and a clamp 26 that fits about the axle 16. The holes in the clamp 26 can be threaded, or nuts 28 may be used to hold the screws 22 in place. As shown in FIGS. 1 and 3, the vertical handles 20 may attach to the bar 18 at each bar end or may be integral with bar 18. The handles 20 are fitted with spherical ends 40. As shown in FIGS. 3 and 4, foot pads 30 are screwed onto the bar 18, one near to each bar end, by means of screws 32 and nuts 34.

In use, the player 12 grasps each handle 20 and places one foot on each foot pad 30 and maintains his balance as the device 10 rolls on wheels 14.

Since obvious changes may be made in the specific embodiment of the invention described herein, such modifications being within the spirit and scope of the invention claimed, it is indicated that all matter contained herein is intended as illustrative and not as limiting in scope.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent of the United States is:

l. A wheeled balancer device comprising a pair of wheels rotatably attached to an axle, said axle being fastened to a bar attached perpendicular to the axle midway between the wheels, with the bar fitted with a foot pad on each side of the axle mounting, and with each end of the bar joined to a rigid handle mounted perpendicular to the bar so that both handles are in parallel vertical orientation when the bar and axle are in the horizontal plane.
