MARTIN BENDER F G. 4 ROBERT M. ASHEN ATTORNEY BALANCING DEVICE This invention relates to a game or toy which can be utilized by young children as well as older children and adults, and is particularly valuable in teaching a child the motor skills of placement of differing objects to achieve desired balanced relationships. There has long been a fascination with jugglers and their remarkable ability to manipulate and delicately balance various shapes and weighted objects. The average individual, and particularly a child without many hours of practice, cannot succeed at achieving the ability to readily manipulate and balance objects in the manner of a juggler or balancer.

Thus, it is an object of this invention to provide a device that can be readily used by children and adults alike to enable them to balance objects (which may be of different shapes) in an interesting manner without requiring the skill of a professional juggler.

Briefly, the illustrated form of the invention comprises a body rack which includes an elongated support structure or frame adapted to be releasibly secured at one end to the body of the user and to extend outwardly therefrom in the forward direction. This releasible securement may be achieved by a harness arrangement which may include a strap or belt that extends around the users waist. Added support for the free end of the frame may be provided as by means of a shoulder or neck strap which is attached to the frame at a place spaced from the users body, the strap passing up and around the neck of the user. The illustrated frame terminates outwardly from the users body in a fitting or connector means which can accommodate a plurality of arms mounted or stacked one on top of another to complete the body rack. The arms may be individually positioned to space apart their ends as desired. The arms preferably have at each end a cup or receptacle means capable of receiving a balancing object. The user of the device will attempt to balance as many of the objects as he can on the arms, and then on underlying objects already on the arms. The objects may be of various shapes, as for example spherical, frusto-conical or flat and disk-like. A drive means may be provided if desired to effect slow rotation of the arms to increase the difficulty of the balancing. It is believed that the invention will be better understood from the following detailed description and drawings in which:

FIG. 1 is a view ofa user and a balancing device comprising a form of the invention, the user being shown balancing a plurality of objects on the device.

FIG. 2 is an enlarged top plan view of the preferred form of the device.

FIG. 3 is a further enlarged cross sectional view taken generally along line 3-3 of FIG. 2.

FIG. 4 is a front view of the device of FIG. 2.

FIGS. 5A thru 5E depict different objects that can be utilized with the device for balancing purposes.

FIG. 6 is a top plan view of the form of the device of FIG. 1 which has a motor means.

FIG. 7 is a sectional view taken generally along line 7-7 of FIG. 6.

Turning now to the drawings, there is seen in FIG. 1 an individual or user 11 having a balancing device 13,

supported on him in operative position, with a body rack of the device extending outwardly in front of him. FIGS. 2, 3 and 4 show the presently preferred form of the device, while FIGS. 1, 6 and 7 shown an alternate form. The user 11 is shown placing a plurality of objects 17 on the balancing device to achieve a balanced effect. As seen best in FIG. 2, the device 13 comprises the body rack 14 which includes an elongated support structure 19 in the form of an open frame. The frame 19 includes two side rods or members 21 which converge toward one another, coming together at their forward ends where they connect to a center fitting 23 which serves as a connector means. The two side members 21 are secured adjacent their divergent rear ends to the respective outer ends of a curved portion 24 of the frame 19 that conforms generally to the waist of the user.

The frame 19 is releasibly supported in the position shown in FIG. 1, with the curved portion 24 engaging the body of the user and with the side members 21 extending outwardly and away from the user in the forward direction. The frame is thus in effect a cantilevered beam adapted to support objects at its outer free end.

A belt or other type of body or waist strap or harness 25 which extends around the users waist and is releasibly connected to the frame 19 may serve as the means to detachably hold the frame in position. In particular, at the rear end of each of the side members 21, a notch 27 may be provided as seen particularly in FIG. 4. The body strap 25 has loops at each end to detachably engage the notches 27. The frame 19 is also supported by a neck or shoulder strap or harness 29 which detachably connects to a forward portionof the frame. For this purpose, rearwardly angled notches 31 may be provided at the upper edges of the side members 21 adjacent their forward ends. Loops at the ends of the neck strap 29 may releasibly engage the respective notches 31.

The body and neck straps may be adjustable in length to accommodate different users. Also, as desired, the straps may be permanently secured to the frame, in

' which case the body strap would be made to open and close or be expandable so that the user could step into it. The frame or support structure may be made of any suitable material such as semi-rigid plastic. This type of material offers the advantage of relatively low cost and lightweight, with sufficient strength to support its own weight and that of the objects. Other material such as metal or wood could be utilized if desired for added strength and durability. The particular illustrated open construction of the frame is preferred as it combines lightweight with sufficient support capability, however other forms or shapes of support structure may be used. The means to releasibly attach the frame to the body and to provide support to its outer end may also vary.

. For example, means might be provided to clip the inner end of the frame tothe users belt. Further, for a particular combination of materials and designs of support structure, body connecting means, arms and balancing objects, it may be desired to use the device without an outer support such as the neck strap.

Turning to FIG. 3 particularly, there is seen the center fitting 23 which is generally an upright tube having a lower or base portion 34, and a cylindrical upper hub portion 35 that extends upwardly from a radial flange portion 37. The fitting 23-serves to support one or more arms 39 utilized with this device to provide the remainder of the body rack 14. Each of the illustrated arms 39 is comprised of a generally elongated straight flat bar 41 having cylindrical cups or receptacles 43 at each end. Each arm 39 also has a fitting portion 45 at its center which serves as a connector means. The fitting portion 45, as seen in FIG. 3, is comprised of two

cylindrical sleeves

47 and 48 which extend vertically upward and downward respectively from the bar 41. The lower sleeve 48 of the arm 39 is received on the hub portion 35 of the central fitting 23. The sleeve 48 may ride on the radial flange portion 37. Each separate arm utilized in the device is preferably constructed in the same manner so that the arms are interchangeable in their relative positions on the frame. The arms, however, can be of different construction. They may also be of different coloring and of different overall length and/or configuration, i.e, they may be curved up or down or to the side. As seen in FIG. 3, a second arm 39' is supported on the first arm 39 through the use ofa cylindrical connector 51 which has its lower half received in upper sleeve 47 of arm 39. The upper half of connector 51 serves as a hub on which a lower sleeve 48' of the arm 39' is disposed. The connector 51 may provide a loose fit for easy relative movement of the arms 39 or they may provide a tight fit whereby the arms will rotate in unison. In FIG. 3 there is seen a third arm 39" mounted on the top of arm 39 by means of an additional connector 51'. The top surface 59 of the uppermost arm 39" may be entirely enclosed in the region of the center fitting for appearance purposes. Thus, this arm would be particularly designed as a top arm when a plurality of arms are stacked one upon another. The receptacles 43 open outwardly and have a cylindrical side wall 61 as seen in FIG. 3. The inner diameter of the illustrated cylindrical wall 61 is sufficient to accommodate the smaller end 63 of a frusto-conical object 65 as shown in FIG. 4. The receptacles 43 can be of varying shapes to accommodate different shaped objects.

Turning to FIGS. SA-SE, there are shown a plurality of objects 17 that may be stacked incident to operation of the illustrated device. The objects can be made of various materials. A lightweight material such as painted styrofoam, hollow plastic forms, balsa wood or the like, provide a number of advantages. They reduce the weight which the user and the frame 19 must support, and they are relatively easy to handle, transport and store. Alternate materials may be used as desired, depending on the strength of the frame, the size of the objects, the number of objects expected to be balanced, the age of the intended user, etc. In utilizing styrofoam or other lightweight construction, it is preferable to provide some added weight in the base of the object, particularly those that are delicately balanced, so as to provide a lowered center of gravity to aid in the balancing. For example, as seen in FIG. A, a styrofoam spherical object or ball 67 has a flat base portion 69 and a weight in the form of a metal insert 71 disposed within the ball at the lower base portion 69. This permits the ball 67 to be readily stacked on a surface in a manner to be further described. FIG. 5B shows a second ball 67' which also has a weight 71' in its flat lower end 69. The balls or other objects may be provided with magnets which attract the metal weights and thereby serve to maintain objects in stacked condition. For example, the ball 67 has a magnet 77 in its top opposite its weight 71 The magnet 77 facilitates another object, particularly another ball such at 67, being balanced on top of ball 67 with the magnet 77 acting to attract the weight 71. FIGS. 5C and 5D depict an object in the form ofa flat circular disk 79 having a metal weight 81 disposed in its center. The objects, particularly such as the disk, may have a mark such as a colorcd circle at their centers to aid the depth perception of the user in placing the object in position and in balancing another object atop that object. FIG. 5E depicts the frusto-conical object 65 with its narrow end 63 and a wider flat end 64.

In utilizing the particular embodiment shown in the drawings, it is preferred to first place the narrow end 63 of the frusto-conical object 65 in the receptacle 43 so that the large flat end 64 is uppermost. FIGS. 1 and 4 show disk-shaped objects 79 placed on the ends 64. This can then be followed by the user placing another frusto-conical object 65 upright on top of the diskshaped object 79, as the user in FIG. 1 is about to do. Alternately a spherical object or ball 67 can be placed on the disk-shaped object 79, as shown in FIG. 4. It should be readily apparent that various combinations of the balancing objects can be utilized. For example, spherical-shaped objects can be stacked on one another, particularly when they incorporate a magnet as shown in FIG. 5B.

FIGS. 1, 6 and 7 disclose an additional embodiment 13A of this invention, wherein the arms 39A mounted on the frame 19A can be caused to rotate in a slow continuous manner while the user of the device is placing the objects thereon. This, of course, further adds to the difficulty in achieving and maintaining a delicate balance of objects. As seen in FIG. 6, a motor or drive means 85 can be rigidly mounted on a side member 21A of the frame. When utilizing the motor 85, it is preferable to attach a transversely extending bar 87 to the side members 21A. The bar 87 may have means such as slots 89 adjacent its ends to releasibly connect to the loops at the ends of the neck strap 29A. The effect of this arrangement, is to move the attachment points of the neck strap 29A outwardly so that there will be no interference between the neck strap and the rotating arms. Such an arrangement is seen in FIG. 1 as well as FIG. 6, mounted on an individual using the device.

The motor 85 is provided with a small output drive gear 91 and an on-off switch 93. Batteries 95 can be supported adjacent the motor to furnish the energy to drive the motor upon actuation of the switch 93. The drive gear 91 engages a larger gear 96 which is attached to or integrally formed surrounding a cylindrical hub portion 45A of an arm 39A. Upon actuation of the motor 85, the drive gear 91 causes the larger gear 96 to rotate together with the arm 39A. Additional arms such as shown at 39A in FIGS. 6 and 7 may be connected to arm 39A as by means of a cylindrical connector 51A so that, the arms will turn together.

It should be apparent that the more arms utilized in the device, the more difficult the balancing becomes. The user of the device of the invention will develop great skill in obtaining the ability to determine the correct placement of a given object on the structure so as not to unduly tilt it and thereby cause objects to fall. For example, when a given object is placed on the support structure in a position, the next object must be placed relative thereto so as to counter balance and not cause the structure to tilt. As can be appreciated, the construction of the support structure together with the utilization of the neck and waist straps help to stabilize the device and will to some extent counteract a disproportionate balance.
