Body strength and conditioning frame structure
BACKGROUND OF THE INVENTION 
     Most body strength and conditioning equipment on the market today, and throughout the years, has been designed for adults, and principally for adult athletes. This equipment is generally heavy in construction and is not easily used by children or adults of slight stature. Further, loading this equipment with a variety of weights is often difficult, if not dangerous, and is not easily accomplished by children. In fact, much of such equipment is intimidating to women and children. Further, each variety of equipment is comprised of an independent design, and it is usually necessary to have a completely separate piece of equipment for each strength and conditioning station. 
     Therefore, it is a principal object of this invention to provide a body strength and conditioning frame structure which provides a basic frame upon which many types of different conditioning equipment can be mounted. 
     A further object of this invention is to provide a body strength and conditioning frame structure that can be converted from one type of conditioning device to another with a minimum of mechanical manipulation. 
     A still further object of this invention is to provide a body strength and conditioning frame structure that can be easily adjusted and utilized by children and adult persons of slight stature. 
     A still further object of this invention is to provide a body strength and conditioning frame structure which is safe to use and adjust even by children. 
     A still further object of this invention is to provide a body strength and conditioning frame structure that can be used by both children and adults. 
     These and other objects will be apparent to those skilled in the art. 
     SUMMARY OF THE INVENTION 
     The present invention comprises a basic horizontal U-shaped frame structure upon which is mounted an upper frame comprised of two parallel sides connected at the top by a cross member. A vertical post or tube is secured to the base frame between the parallel sides, and extends upwardly to slidably receive the vertical portion of a T-shaped frame which is journaled in a slide mechanism on the inner face of each of the sides of the upper frame. 
     A plurality of parallel rods extend outwardly from the vertical member of the T-shaped frame, and these rods are spaced from, but in alignment with similar rods that extend horizontally inwardly from the inner face of the two sides of the upper frame. Weight members having center apertures are slidably mounted on these rods, and they can be moved back and forth between aligned rods by reason of having a horizontal thickness greater than the space between aligned rods. 
     The above-described basic frame is adaptable to having a variety of conditioning equipment mounted thereon. A particular mechanism is shown which has an arm lifting bar secured to the upper portion of the T-shaped frame. A seat portion is secured to the horizontal base frame. The bar secured to the upper portion of the T-shaped frame has hand gripping portions comprised of two spaced-apart inclined U-shaped members each having an upper horizontal gripping portion and lower horizontal gripping portion. Persons of small stature utilize the lower gripping portions, whereas taller persons are able to utilize the upper gripping portions.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     The numberal 10 designates the basic frame of this invention which is best shown in its entirety in FIG. 7. Frame 10 is comprised of a horizontal U-shaped base frame 12 which is comprised of two sides 14, a front 16, and a cross member 18. This frame is normally of welded construction and is comprised of square tubing material. 
     An upper frame 20 is rigidly secured in any convenient manner to the ends of cross member 18 of base frame 12. Upper frame 20 is comprised of parallel sides 22 which are rigidly connected at the top ends thereof by top member 24. 
     T-frame 26 is movably mounted within the plane of sides 22 of upper frame 20. T-frame 26 is comprised of a hollow vertical square tube 28 which is rigidly secured to a horizontal top member 30. A vertical square tube 32 (best shown in FIG. 6) is rigidly secured to the center of cross member 18 of base frame 12 and slidably extends into hollow tube 28 of T-frame 26. Vertical tube 32 is preferably covered with a smooth material such as plastic layer 34 to reduce slidable friction with tube 28. 
     Vertical rods 36 are rigidly secured in any convenient manner to the upper and inner faces of sides 22 of upper frame 20. These rods are best shown in FIGS. 1, 5, 7, and 8. Rollers 38 (see FIG. 5) are secured to the opposite ends of top member 30 of T-frame 26 by means of nut, bolt and washer assemblies 40. 
     As best shown in FIG. 7, horizointal rods 42a, 42b and 42c are welded or otherwise rigidly secured to tube 28 of T-frame 26 and extend horizontally outwardly therefrom almost one-half distance towards the sides 22 of the upper frame 20. Similarly, horizontal rods 44a, 44b and 44c are rigidly secured to the inner face of sides 22 and are in alignment with the horizontal rods 42a, 42b and 42c, respectively, when the T-shaped frame is in the lower position shown in FIG. 7. 
     Weights 46 have a center aperture (not shown) which is just slightly larger than the diameter of the aforementioned rods, and can be slidably mounted on these rods. The weights 46 have a horizontal width greater than the space 48 which exists between the opposite ends of the above-described rods. Thus, with the rods in position of alignment as shown in FIG. 7, the weights can be slidably moved from the rods 44 to the rods 42, and visa versa, without fully removing the weights from either of the rods. If it is necessary to remove a weight from any given rod, this can be done when the positions of the normally aligned rods are in a condition of disalignment as shown in FIG. 8. 
     As best shown in FIG. 4, a bottom plate 50 is welded or otherwise secured to the bottom of tube 28. A pair of rubber cushion elements 52 are secured to the bottom face of the plate by means of bolt means 54. As shown in FIG. 2, an upper clevis element 56 with an aperture therein is welded to the front side of the lower end of tube 28, and registers with a lower clevis element 58 which is welded or otherwise secured to the front center portion of cross member 18 of base member 12. A padlock or the like can be extended through the registering apertures 59 (FIG. 6) to lock the T-shaped frame in its lower position when not in use. 
     Apertures 60 are located in the upper center portion of top member 24 of upper frame 20 to permit the attachment of various conditioning equipment. Similarly, apertures 62 are located (FIG. 7) in top member 30 of T-shaped frame 26 for the same purpose. Apertures 64 are similarly located in the center portion 16 of base frame 12. 
     With reference to FIGS. 1 and 2, a seat frame 6 can be bolted or otherwise secured to the base frame 12 by utilizing the apertures 64. Frame 12 can include an inclined seat portion 68 which will permit a person to support himself in a sitting position with his back to the upper frame 20. 
     A bar support 70 is mounted by utilizing the apertures 62 in upper member 30 of T-shaped frame 26. A horizontally disposed V-shaped bar 72 is mounted in bar 70. The opposite ends of bar 72 terminate in an inclined U-shaped member 74 comprised of an upper gripping horizontal portion 76 and a lower horizontal gripping portion 78. Gripping elements 80 can be secured to each of the members 76 and 78. 
     In the normal operation of this invention, the operator can slide any combination of weights from the storage position on rods 44a, 44b, and 44c to the operating position on rods 42a, 42b and 42c. The alternate position of weights 46 is best shown in FIG. 4, and in FIG. 8. 
     The operator can then sit in seat portion 68. Depending upon his or her stature, the hands can be extended upwardly to grip either the lower gripping portions 78 or the upper gripping portions 76. This enables the operator then to lift the T-shaped frame 26 to an elevated position on rods 36. The plastic coating material 34 on the vertical tube 32, as well as the rollers 38 acting in conjunction with the rods 36 reduces the friction of related components. 
     By utilizing the aptertures 60, 62 and 64, a wide variety of exercising and conditioning equipment can be adapted to the basic frame. 
     It is, therefore, seen that the device of this invention can be used by children and persons of slight stature. The weights imposed on the T-shaped frame 26 can be easily adjusted even by children without danger of injury. The rubber cushions 52 function with the plastic layer 34 and the rollers 38 to make the device operate quietly. 
     It is, therefore, seen that the device of this invention accomplishes at least all of its stated objectives.
