ABSTRACT:
TECHNICAL FIELD
The present invention relates to a sled exerciser and, more particularly, to a full body, adjustable weight sled exerciser included within a stationary frame so as to be used indoors.
BACKGROUND OF THE INVENTION
In sports, primary in football, a sled exerciser is used for tackle and blocking training, with a coach or trainer standing on a frame and the individual running into a padded arm and pushing the frame backwards, using the weight of the coach or trainer as the resistance. Obviously, such an arrangement cannot be used indoors, as during off-season practice or during inclement weather. Moreover, the weight used as resistance is not well-controlled and cannot be assured in providing the proper workout for the individual. Thus, a need remains in the art for an exercise sled, useful (for example) in tackle training, that can be used indoors and utilizes a proper, well-controlled means of resistance against the individual making the tackle/block.
SUMMARY OF THE INVENTION
The need remaining in the prior art is addressed by the present invention, which relates to a sled exerciser and, more particularly, to a full body, adjustable weight sled exerciser included within a stationary frame so as to be used indoors.
In accordance with the present invention, a padded vertical bar (i.e., sled) is mounted within a three-sided heavy-duty frame assembly, with the bar connected to an overhead track assembly that rides along a C-channel member from the front to the back of the assembly. In accordance with the present invention, a set of pulley-mounted weights are attached to the overhead track assembly and used to provide resistance against the individual pushing against the padded sled. Advantageously, the weight is adjusted to provide the proper workout for the individual using the system (i.e., a lower set of weight for youths, and a large weight resistance for adults/professionals).
In a preferred embodiment of the present invention, the pulley-mounted weights are attached to a second, front frame member which extends beyond the frame assembly supporting the sled. In this embodiment, the weights remain easily accessible, yet out of the way of someone using the system.
The pad on the vertical bar may be adjustable, or interchangeable with longer (or shorter) pads, as necessary. Alternatively, a fixed, relatively long pad may be used. In any case, padding is required to prevent injury to someone using the system.
Other and further embodiments and advantages of the system of the present invention will become obvious during the course of the following discussion and by reference to the accompanying drawings.
