Description

This application is a continuation of U.S. patent application Ser. No. 10/377,458, filed November Feb. 28, 2003, to which application priority is claimed.

BACKGROUND OF THE INVENTION

1. Field of the Invention
The present invention relates to a swinging implement, adapted to simulate a rowing exercise.
2. Description of the Prior Arts
Rowing simulating implements are already known.
These prior rowing simulating implements, which are conventionally called “rower” have a lot of different constructions, but are all constituted by a seating plane or panel, of movable construction, and means adapted to simulate the “rowing” exercise.
The prior rowing implements are usually divided into two classes: the “belt” rowing implements, which comprise a bar operating as conventional oars, said bar being coupled through a belt to a braking system, and the “arm” implements, comprising two rods simulating the oars and being coupled to a braking system.
Starting from the assumption that such an implement is specifically designed for simulating a water rowing, and that the makers have designed means for rendering a ground training fully similar to a water rowing training, a substantially difference still exist between the two mentioned types of sports exercise.
In fact, an athlete trained in water, engages his/her body not only in the rowing effort, but also in holding a proper equilibrium condition on the watercraft.
In fact, due to the configuration of the watercraft or boat, and because of the fluid nature of water, the surface or plane on which the athlete works does not hold a fixed inclination, but the inclination thereof is continuously changed.
This instability condition causes the athlete to be subjected to a proprioceptive type of reaction involving all the muscle fascia of the athlete, thereby increasing the effort provided during the exercise.
FIG. 1 illustrates a typical prior rower, comprising a supporting framework 1, bearing on a floor through supporting elements 2, which supports the framework in a “rigid” manner.
The rower comprises a seating plane 3 which can freely slide along the supporting framework 1, foot rests 4, fixed to the supporting framework 1, a flywheel 5 which can freely rotate with respect to a pivot axis 8 fixed to the supporting framework 1, and on the pivot pin of which is entrained a belt 6 ending with a handle 7.
Such a rower construction allows the athlete to simulate the rowing exercise, by pulling the handle 7, thereby causing the flywheel 5, which usually comprise a braking system for adjusting the athlete effort, to rotate.
The seating plane 3 can freely slide in order to allow the athlete or user to bend and extend his bottom or lower limbs, providing effort through the athlete feet on support elements 4, thereby facilitating the rowing exercise.
Yet another rowing apparatus as disclosed by Watterson (U.S. Pat. No. 5,013,033) also includes a handle connected to a flywheel through a belt, and the flywheel is complicated and hidden in a base support housing. And this rowing apparatus is unable to simulate the swinging movement.
Further rower construction are moreover known, which substantially differ with respect to the adopted braking system (hydrodynamic, magnetic, oleodynamic, aerodynamic), or with respect to the arrangement of the component parts thereof.
Yet other rowing apparatuses have been developed to have a function of simulating the swinging movement. For example, U.S. Pat. No. 199,432 disclosed a rowing apparatus comprising a rocker mounted on a base through a plurality of teeth, wherein the rocker can swing relative to the base. Another apparatus as disclosed in U.S. Pat. No. 3,659,844 comprises a platform pivotally mounted on a base through a pivot and a plurality of helical springs radially connected between the base and the platform. Although, these two apparatuses can simulate swinging motion, their swinging devices are too complicated in structure and do not have any devices designed for preventing the athlete or user from following as the implement center of mass is overcome or exceeded.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.

SUMMARY OF THE INVENTION

Accordingly, the aim of the present invention is to provide such an implement adapted to simulate a rowing exercise, which, in particular simulates as faithfully as possible, the effort which an athlete or user would provide for rowing through water.
Within the scope of the above mentioned aim, a main object of the present invention is to provide such an implement which is adapted to simulate the typical swinging movement of a oar boat in its floating through water, thereby subjecting the user to proprioceptive stimulations inducing said user to hold the implement centered during the exercise.
Yet another object is to provide such an implement which can be applied to any types of “rower”, even of a conventional existing type.
Yet another object of the present invention is to provide such a simulating implement adapted to fully train all the body systems involved in a water rowing exercise, i.e. the muscle (power) system, the cardio-muscle (resistance) system, and the neural-muscular (equilibrium and space movement control) system.
According to one aspect of the present invention, the above mentioned aim and objects, as well as yet other objects, which will become more apparent hereinafter, are achieved by a swinging implement designed for simulating a rowing exercise, comprising a supporting framework, adapted to bear on a floor through support elements, and including a seat plane, which can freely slide along said supporting framework, characterized in that said implement further comprises swinging elements adapted to allow said bearing framework to swing with respect to said floor, thereby inducing the implement user to search an equilibrium condition during the exercise.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

With reference to the number references of the above mentioned figures, the swinging implement, designed for simulating a rowing exercise, according to the invention, and as shown in FIG. 1, generally comprises a supporting framework 1, bearing on a floor through supporting elements 2 and including a seating plane or panel 3, which can freely slide along the supporting framework 1.
According to the invention, in its embodiment shown in FIG. 2, the supporting framework 1 is not made rigid with the ground, but rests on arched bases 22, inducing the user or athlete to continuously search to hold an equilibrium condition during the exercise.
Said bases are advantageously provided with extension elements 23, designed for preventing the athlete or user from following as the implement center of mass is overcome or exceeded.
FIG. 3 shows a possible solution similar to that which has been above disclosed.
In this case, the flywheel 5 is arranged in a horizontal position, in order to lower the center of mass of the athlete-implement assembly.
FIG. 4 shows a further embodiment, in which the main structure 41, to which the remaining part of the implement is coupled, is connected through articulated joints 43 to the mentioned bases 42.
The two bases 42 are rigid with the bearing ground, but the implement can swing with respect to the ground.
FIG. 5 shows an implement similar to that shown in FIG. 4, but including bearing brackets 50 provided for bearing on springs 51 rigid with the bases 42, thereby aiding the athlete or user in holding a centered position, while operating as limit elements for the implement swinging movements, with respect to the axis constituted by the pivot pins 52.
It has been found that the invention fully achieves the intended aim and objects.
In fact, the invention has provided a swinging implement, adapted to simulate a rowing exercise, and providing a ground based athlete or user with the same type of training which he/she would obtain in water.
For achieving that result, the implement can sideway swing, either in a free or guided manner, as shown in the disclosed embodiments, while the invention actually relates to the concept, and is not limited to the shown and/or disclosed embodiments.
In practicing the invention, the used materials, as well as the contingent size and shapes, can be any, depending on requirements and the status of the art.
