DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference now to the drawings, and in particular to FIGS. 1 through 4 thereof, a new combination stack weight selector and add-on assembly embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.
As best illustrated in FIGS. 1 through 4, the combination stack weight selector and add-on assembly 10 generally comprises a selector/support member 11 having a handle member 12 and an elongate shaft member 15 being securely and conventionally attached to the handle member 12 for selection of weights 24 to be lifted on a weight-lifting machine 25. The handle member 12 has a bore 13 extending therein through an end thereof, and has a knurled exterior surface 14, and is cylindrical shaped. The elongate shaft member 15 has a first end portions 16 which is threaded into the bore 13 of the handle member 12, and has a second end portion 7 having a laterally-extended slot 19 being disposed therein. The elongate shaft member 15 also has a knurled exterior surface 18 disposed between the first and second end portions 16, 17. The selector/support member 11 also includes a spring member 20 being securely and conventionally disposed in the laterally-extended slot 19, and includes a ball member 21 being conventionally attached to the spring member 20 and being partially and biasedly exposed from the laterally-extended slot 19 to effectively retain the second end portion 17 of the elongate shaft member 15 either in a support for the stack of weights or in one of the weights 24 of the stack of weights which are to be lifted by the user.
One or more weight members 22 are supported upon the selector/support member 11. Each weight member 22 has a hole 23 being centrally-disposed therethrough and through which the elongate shaft member 15 is removably extended to support and add-on the weight member 22 to the stack of weights 24 to be lifted by the user. The weight member 22 is disc-shaped, and the hole 23 is disposed along an axis thereof with the weight member 22 being removably securely supported upon the knurled exterior surface 18 of the elongate shaft member 15.
In use, the user mounts one or more weight members 22 upon the elongate shaft member 15 and inserts the elongate shaft member 15 in either a support for the stack of weights or in one of the weights 24 to select the weights 24 the user is gong to lift using the conventional weight-lifting machine 23. All of the weights 24 located above the elongate shaft member 15 will be the weights 24 to be lifted by the user.
As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.
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 combination stack weight selector and add-on assembly. 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.
