S Claims. (Cl. 272-70) The present invention relates to an ambulatory rocking device intended for amusement and exercising purposes and adapted to support the body of a user for rocking movement from side to side while maintaining a position, traveling forwardly or rearwardly, turning, or accomplishing other maneuvers, all by controlled shifting of the users body weight.

The recognition of the dependence of good health on regular exercise, preferably coupled with mental recreation, has led to increased attention to physical culture and the values of active play for adults and children. Improved health and physical appearance, increased muscle tone, and enhanced gracefulness and coordination are usual results of proper exercise.

Children run and play and engage in sports activity to an extent usually adequate for body development. Particularly for those adults who are engaged in sedentary occupations, however, it is desirable to participate in purposeful exercise unless some form of play exercise appeals to the individual. As a purposeful exercise, calisthenics are frequently performed.

Children and adults frequently utilize various auxiliary devices during periods of exercise in order to relieve the boredom of simply moving the arms and legs about and, in many cases, to concentrate on the development of certain muscles and body parts. Although perhaps unconsciously, when children stand with their feet apart on a board balanced on a rock or other object and cause the board to teeter from side to side, they are in effect exercising their leg muscles and improving their poise, co-

ordination and body balance. Gymnasiums are usually equipped with leg exercising apparatus designed and manufactured to accomplish some of these desirable results. Other devices which are available and are generally classified as toys, such as hula hoops, enable the user to exercise and develop various muscles of the body while at the same time deriving considerable pleasure and amusement from the device. The essence of the present invention resides in the provision of a device adapted for both amusement and exercise of children and adults and which enables the user to rock forwardly and rearwardly and from side to side thereby to exercise the legs in particular and to enable the user to achieve improved coordination and balance. In order properly to employ and derive the greatest benefit from the device, a certain degree of proficiency borne of practice is required. Thus the device tests and serves as a challenge to the skill of the user Yso as to enhance the amusement and pleasure attending its use.

Accordingly, it is an object of the present invention to provide a novel ambulatory rocking device.

Another object is to provide a rocking device especially adapted for amusement and exercise.

Another object is to provide a device intended to afford users thereof training in balance and body coordination.

Another object is to provide a device of the type described which is adapted for rocking movement from side to side, forwardly and rearwardly, or combinations of these movements, incident to corresponding shifting of the weight of the body on the device.

Another object is to provide such a device on which a person using the same can walk with a rocking movement.

Another object is to provide a rocker construction which facilitates control of rocking or walking movements.

These, together with other objects, will become more fully apparent upon reference to the following description and accompanying drawing.

In the drawing:

Fig. l is a front elevation of a rocking device embodying the principles of the present invention and showing a user in operating position.

Fig. 2 is a somewhat enlarged top plan view of the rocking device.

Fig. 3 is a fragmentary somewhat enlarged front elevation of an end portion of the rocking device.

Fig. 4 is a fragmentary transverse section taken on line 4 4 of Fig. 3.

Referring more particularly to the drawing, an ambulatory rocking device embodying the principles of the subject invention is illustrated in use in Fig. 1 and includes an elongated substantially rectangular platform or girder 10 having opposite side edges 11, a front edge 12, a rear edge 13, and upper and lower edges 14 and 15. As will subsequently be apparent, the platform is essentially a rigid spacing member and may be of various congurations. The designation of front and rear edges is for purposes of descriptive convenience and is not intended to limit orientation of the platform. It will be readily apparent as the description proceeds that either edge 12 or 13 could with corresponding propriety be designated as the front or rear edge of the platform.

A pair of shoes 2i) of rigid sheet material is provided for supporting the platform 10 at opposite side edges 11 thereof. The shoes have front and rear edges 21 and 22 which lie in planes respectively containing the front and rear edges 12 and 13 of the platform. Stated otherwise, the shoes are of the same width as the platform in the embodiment shown. The shoes include longitudinally spaced parallel mounting or spacing flanges 24 having tabs 25 rigidly connected by bolts 26 and nuts 27 to the platform in uniformly inwardly spaced relation to the side edges thereof. The mounting anges are rigidly downwardly extended in right-angular relation to the platform. The mounting flanges are ilat, of substantially the same length, and terminate in straight lower edges. The shoes also include arcuate rockers or rocking plates 30 having downwardly convex surfaces 31 substantially in the form of a quadrant of a circle and integrally outwardly upwardly curved from the lower edges of their respective mounting anges. The rockers 3d have the same cylindrical radius and are concentric to individual axes spaced inwardly from the side edges of the platform in parallel spaced relation to each other. The rockers have upper sides connected by means of screws 32 to the side edges of the platform. Thus, it will be evident that the rockers are upwardly outwardly curved transversely of the platform. It is also to be noted, and especially in Figs. 3 and 4, that the surfaces 31 of the rockers are longitudinally outwardly convexly curved between the front and rear edges thereof; the lower edges of the mounting anges are not curved however. The rockers also have the same longitudinal curvature but the radii of curvature in this instance is substantially greater than the radius of transverse curvature of each rocker.

Foot rests 36 are mounted on the platform 10 adjacent to the opposite side edges 11 thereof and include side anges or ledges 37 rigidly connected to the side edges of the platform and upwardly extended therefrom in substantially right-angular relation to the upper surface 14.

AThe side flanges are preferably integral with the sides position on either side.

of the rockers 30 so as to form upward extensions of the rockers. The side flanges terminate in upper edges 3S and are reversely bent downwardly from said side edges.

The foot vrests also include flat foot plates 4i) integrally grecs.

Operation The operation of the described embodiment of the subject invention is believed to be readily apparent and is briefly summarized at this point.

The device is supported on the floor or the ground Si) with lower edges of the mounting flanges 24 in ground engagement. Because of the described construction of the shoes 20, the platform it? is supported in substantially horizontal position by the lower edges of the mounting iianges.

In order to use the device for rocking purposes, the

Vuser steps on the platform it)Y between the foot plates 40. This does not result in forward and rearward or side to side rocking of the device because the weight is concentrated centrally of the platform and because such weight is supported on the straight lower edges of the mounting iianges. The user then moves his feet uniformly outwardly of the platform onto the foot plates preferably positioning the heel against ythe rear edge i3 of the platform and the foot plates, and positioning the side edge of the foot against the side flanges 37. As long as the weight on each foot is uniformly distributed, the horizontal attitude of the platform l@ is maintained. Commercial embodiments of the subject invention are preferably designed so that as a user stands on the device with his feet against the foot plates, his legs are substantially normal to the plates.

By shifting the weight of the body from one foot to the other, it will be evident that the platform can be rocked from side to side on the rockers Sil. During these movements, .the side flanges 37 prevent the feet from slipping laterally off from the foot plates 4i). The normal or average range of rocking is approximately forty-tive degrees measured from the neutral horizontal position of the platform to the maximum laterally tilted This is, of course, determined by the curvature of the rockers 30 and the dimensions of the device as well as the ability of the user. The forty-five degrees noted corresponds to the preferred commercial embodiments of the device. Thus, when the platform is midway between its range of movement, the foot plate itl on which the weight is concentrated is substantially horizontal. Accordingly, the described angularity of twenty-two and one-half degrees between the foot plates and the platform allows for a maximum amount of control of tilting action.

Concurrently with side to side tilting, the platform 10 can be tilted forwardly and rearwardly simply by shift- .ing the body forwardly and rearwardly on the platform,

as will be evident. Still further, while keeping the legs substantially stiff and oy combined action of lateral shiftmg of body weight and forward movement of opposite lsides of the platform, the user can ambula'te or walk along on the device. More specifically, the side of the platform on which the weight is relieved is shoved forwardly by the foot of the user so as to pivot the platform on the shoes 2d on which the weight is concentrated. By alter- 'nately shifting and pivoting, the described walking can bejperformed.

From the foregoing it will be evidentI that a highly amusing device adapted for both pleasure and exercise has been provided. Inasmnch as the device is designed for effecting lateral and forward and rearward rocking, it is especially helpful in developing body balance of users thereof. The rocking device is simple and economical to construct and can readily be enjoyed after a certain amount of practice.

Although the invention has been herein shown and describedV in what is conceived to be the most practical and preferred embodiment, it is recognized that departures may be made therefrom within the scope of the invention, which is not to be limited to the details disclosed herein but is to be accorded the full scope of the claims -so as to embrace any and all equivalent devices and apparatus.
