     DETAIL DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Referring to the drawings and in particular to FIGS. 1 to 3, there is illustrated an infant&#39;s toy gym set embodying the present invention. Infant, as used herein, is defined as a child ranging between three months to one year of age. As shown, the toy gym set 10 of FIG. 1 comprises a pair of opposed upright supports 11 and 12. Each upright support 11 and 12 includes a pair of leg members 11A, 11B and 12A, 12B which are arranged to converge toward the upper ends thereof. The upper ends of the respective leg members 11A, 11B and 12A, 12B are connected by a fitting 13 and 14 respectively. As seen, the fittings 13 and 14 comprise a generally V-shape fitting having a pair of sockets for slid ably receiving the upper ends of the corresponding leg members. The arrangement is such that the leg members are frictionally received within the corresponding sockets of the respective fitting. Each fitting 13 and 14 is also provided with a laterally off-set socket 13A and 14A respectively which provides the end support for a cross bar 15; which is preferably round in cross-section. To stabilize the end supports 11 and 12, a tie bar 16 and 17 is interconnected between the respective pair of leg members 11A, 11B and 12A, 12B. This is readily attained by a T-shape fitting 18 which is slipped onto the respective legs whereby the cross arm of the fitting 18 slides onto the respective leg whereby the cross arm of the fitting 18 slides onto the respective leg with the tie bar fitted between the opposed stem 18A portion of the T fitting 18. Rotatably and slidably mounted on the respective tie bars 16 and 17 are a plurality of beads, propellers and other amusing articles A which can be readily manipulated by an infant or its parents for imparting additional play value or activity to the toy 10. 
     In accordance with this invention, an inflatable means or chamber 19 is rotatably mounted on the cross bar 15. In the illustrated form of the invention, the inflatable chamber 19 is defined by a cylindrical outer shell 20 formed of a suitable plastic material. Disposed axially of the shell 20 is a center sleeve 21 for receiving the cross bar 15 about which the chamber 19 is free to rotate. Opposed end walls 22, 22 are secured between the outer shell 20 and sleeve 21 to define an air tight chamber 19. A suitable valve 23 is provided to allow for inflating and/or deflating the chamber 19. 
     Disposed within the chamber 19 and free to tumble therein as the chamber 19 is rotated are a plurality of individual playthings or beads. It will be understood that the playthings 24 may simulate any figure or shape that may appeal to an infant. To facilitate the tumbling of the playthings within the chamber when rotated, the chamber is provided with a plurality of circumferentially spaced internal vanes 25 which are radially disposed therein. Thus, it will be apparent that as the chamber is rotated about the cross bar 15, the internal vanes will cause the playthings to be caught thereby and released when the vanes reach the zenith of its rotation. The rotating chamber thus presents an amusing and appealing attraction to an infant as the playthings 24 disposed therein rise and fall upon the continued rotation of the chamber. The tumbling of the playthings within the chamber also produces a random sound which also supplements the visual appeal. If desired, the outer shell may be suitably decorated in colors which may also impart thereto a kaleidoscope effect. 
     Within the construction described, it will be apparent that the toy gym set 10 may be mounted above a crib and utilized as a crib toy or it can stand on a floor and be utilized as a floor toy. In either event, the infant lying below the inflatable chamber can be readily amused by the action, sound and sight of the rotating chamber and the tumbling playthings disposed therein. 
     FIG. 4 illustrates a modified form of the invention. In this form of the invention, the end supports 30A, 30B are constructed as hereinbefore described. In this form of the invention, the inflatable chamber 30 comprises an outer shell 31 which is cylindrical in shape and sealed at the ends by end walls 32 and 33. As shown in FIG. 4, the cross bar 34 is projected through the sleeve 35 extending between side walls 32, 33 and sealed thereat to define an annular chamber 31, which is supported on the cross bar 35. The cross bar in turn is rotatably journalled in the support fittings 37 and 38. As hereinbefore described, the inflatable chamber includes the internal vanes 39 and internally disposed playthings 40. In this form of the invention, rotation of the inflatable chamber 30 is effected by rotation of the cross bar 35 to which the inflatable chamber is fixed, e.g. pins 41 extending to mounting sleeves 39A connected to the end walls 32, 33 of the inflatable chamber. If desired, a motor means M may be connected in driving relationship to the cross bar 35 as shown to effect rotation of the chamber 30 connected to the cross bar 35. In the illustration embodiment, the motor M comprises a spring wound motor which is suitably geared to one end of the cross bar as shown to effect rotation thereof. A small electrical motor may be substituted in lieu thereof. In all other respects, the embodiment of FIG. 4 is similar to that of FIGS. 1 to 3. 
     FIG. 5 illustrates a further embodiment of the invention. This form of the invention differs from that hereinbefore described in that the inflatable chamber 50 comprises an outer shell 51 which is sealed by end walls 52 and 53. Connected to the respective end walls 52 and 53 is an outwardly projecting trunnion or axle 52A, 53A respectively. The outer ends of the trunnions 52A, 53A are rotatably supported in the end fittings 54, 55 respectively of the end supports 56, 57. In all other respects, the toy gym set is similar to that hereinbefore described with respect to FIG. 1 
     While the embodiments herein described are constructed so as to permit the inflatable chambers 19 and 50 to be manually rotated, it will be understood that if desired, the inflatable chamber could be motorized by a small mechanical or electrical motor as shown in FIG. 4, which can be suitably geared to effect rotation of the chamber when the motor is activated. Also, it will be understood that a music box can be suitably associated with the rotating chamber which is actuated when the chamber is rotated. 
     Although the preferred embodiment has been illustrated and described, it will be obvious to those skilled in the art that various modifications may be made without departing from the spirit and scope of this invention.
