For children, conventional weight resistance training to build strong bones and muscles may not be suitable because weight equipment sized for adults can be too heavy or dangerous for children to use. Therefore, a need exists for a new and improved fitness activity apparatus that enables children to safely engage in weight resistance training. In this regard, the various embodiments of the present invention substantially fulfill at least some of these needs. In this respect, the fitness activity apparatus according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose of enabling children to safely engage in weight resistance training.
- The present invention provides an improved fitness activity apparatus, and overcomes the above-mentioned disadvantages and drawbacks of the prior art. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide an improved fitness activity apparatus that has all the advantages of the prior art mentioned above.

FIGS. 1-3 illustrate the improvedfitness activity apparatus 10 of the present invention. More particularly, the fitness activity apparatus is a sled used for children's sports activity and training. The sled is a four-footed structure with opposedfront leg posts elbow couplings front handle bar 20. Opposedrear leg posts couplings rear handle bar 30 at an intermediate height lower than the front handle bar. Each of the leg posts has abroad foot couplings support bars end caps upper ends couplings optional rope 60 has oneend 62 removably connected to the rear handle bar by aclip 64. It should be appreciated that for some uses, including use by taller children, the rope may be connected to the front handle bar, so that the user pushes the sled from the opposite direction. Acircular weight plate 66 having abottom 68 rests on the support bars. The weight plate has a diameter slightly less than the diagonal separation between diagonally opposed vertical front and rear leg posts. The weight plate diameter is significantly greater than any of the spaces between adjacent leg posts, so that the plate remains retained securely on the platform provided by the support bars, and cannot slide off between any of the leg posts. The T-couplings that connect the support bars to the leg posts havehorizontal portions horizontal portions - In the current embodiment, the sled has a trapezoidal shape, with the
front handle bar 20 being shorter than thesupport bars rear handle bar 30. Portions of the T-couplings' 40, 42, 44, 46center legs lobes lobes - The dashed lines in
FIG. 3 show theweight plate 66 in the process of installation into or removal from the sled. With the weight plate nested firmly at the junctions between therear leg posts support bars front handle bar 20 as shown, with alimited clearance gap 98. The clearance gap is less than the diameters of thefront leg posts - The sled can be viewed as a frame having four vertical posts: a left rear post and right rear post (
rear leg posts 22, 24) and a left front post and a right front post (front leg posts 12, 14). The left rear post and right rear post are connected by a rear lateral bar (rear handle bar 30). The left front post and right front post are connected by a front lateral bar (front handle bar 20). The left rear post and left front post are connected by a left side bar (support bar 48). The right rear post and right front post are connected by a right side bar (support bar 50). The left side bar and right side bar are at a common level to provide a support platform configured to support acircular weight plate 66 having a selected plate diameter. The left rear post and right front post are spaced apart by a first diagonal spacing greater than the plate diameter by a limited first gap. The right rear post and left front post are spaced apart by a second diagonal spacing greater than the plate diameter by a limited second gap. The rear lateral bar is positioned at a first vertical level, and the front lateral bar is positioned at a different second vertical level. The left side bar and the left front post define a left interior corner, the right side bar and the right front post define a right interior corner, and the rear lateral bar has a midpoint surface facing toward the left and right interior corners. The left interior corner, right interior corner, and real lateral bar midpoint define a clearance triangle. A circumcircle of the clearance triangle passing through all three corners of the clearance triangle has a diameter greater than the circular weight plate diameter by a limited first clearance amount, such that the circular weight plate may be installed and removed by positioning a forward edge of the circular weight plate against the left and right interior corners and bypassing the rear lateral bar with a rear edge of the circular weight plate. The left side bar and right side bar are positioned at a third vertical level different from the first and second vertical levels. The rear lateral bar is positioned above the left side bar and right side bar. The circular weight plate has a selected plate thickness. A lower surface of the front lateral bar and the support platform are separated by a limited vertical distance greater than the plate thickness by a limited vertical clearance amount. Each of the four vertical posts has afoot couplings couplings - In the current embodiment, the sled has the following dimensions: the cylindrical tubing elements and fittings all have a size of 2 inch. Each foot has a diameter of 2½ inch. The gap width between the opposed front leg posts 12, 14 is 9 inch. The gap width between the opposed rear leg posts 22, 24 is 14 inch. The overall length of the
fitness activity apparatus 10 is 16 inch, the maximum width is 18 inch, the minimum width is 13 inch, the maximum height is 14¼ inch, and the minimum height is 13 inch. Theweight plate 66 has a diameter of 17½ inch and is held 6 inch above the floor by the opposed support bars 48, 50. -
FIGS. 4 & 5 illustrate an alternative embodiment of the improvedfitness activity apparatus 200 of the present invention. More particularly, thefitness activity apparatus 200 is a climbing structure shown in a disassembled condition inFIG. 4 and an assembled condition inFIG. 5 . The climbing structure is a modular unit that has an equilateral triangular prismatic form with three square or rectangular faces joined at parallel edges and with triangular end faces. The structure is formed by threeedge bars cylindrical sleeves bars cross bars semi-cylindrical channels pins 286 or screws throughholes 288 in each of the fittings with channels and an axially registeredhole 290 in adjacent connecting bars to avoid slippage. The cross bars may be arranged with different spacings for different activities, user size, and user skill level, with one of the two square or rectangular faces that provide climbing surfaces above the floor shown having two cross bars and one having three cross bars. Optionally, a panel with climbing wall handles or a cargo net (not shown) can each be removably attached to either of the two square or rectangular faces that provide climbing surfaces above the floor. - While current embodiments of a fitness activity apparatus have been described in detail, it should be apparent that modifications and variations thereto are possible, all of which fall within the true spirit and scope of the invention. With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
- Therefore, the foregoing is considered as illustrative only of the principles of the invention.
- Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
