In house exercising has become a general feature of modern life. The combination of an exercising effort with a training action enhances the value of such pursuit. Kayaking is a sport that involves a variety of bodily actions that take place at the same time that are not easily simulated. It is, amongst others, an object of this invention to provide equipment that extensively simulates a kayak workout even to the extent of permitting a user to make adjustments in numerous areas in benefiting from such workout.
Field of the Invention
This invention relates to a paddling action simulating exerciser. While not so limited the exerciser finds useful application in simulating a kayak paddling action.
Description of the Prior Art
Kayak training equipment known to the applicant often utilise a large fan to provide the workout resistance. This has the effect of rendering such equipment clumsy to transport between locations of use. A system involving a flywheel is also used in providing the required resistance in simulating a kayak paddling operation. The inertia of the flywheel requires a large initiating force at the commencement of a paddling routine that, once running, reduces the effort thus reducing the effectiveness of the exercise. As with the fan utilising variation, the flywheel variation also requires effort to mover between locations of use.
The invention is now described, by way of example, with reference to the accompanying drawings. In the drawings
Referring to
The trainer 10 comprises a paddle action simulating formation in the form of a hollow open ended paddle simulating pole 12, a cord 14 that extends along the pole 12 in linearly displaceably passing there through while its opposite end lengths 14.1, 14.2 extend beyond the opposite ends 16 of the pole 12, a hollow spacer 18 extending between a sealing facility 20 and an anchoring layout including a cord guiding layout 22 along which the free ends 14.3, 14.4 of the cord 14 are secured to expansibly contractible resilient means in the form of a spring 24 extending within the spacer 18.
The cord 14 passes against being damaged when subjected to linear displacement along the pole 12. The cord 14 under conditions of linear displacement along the pole 12 generate a factional resistive action in the pole 12 as being formed with reduced diameter opposite ends in the form of fitted bushes 26, detail of one being shown in
The spacer 18 and seating facility 20 is fitted with elevating means in the form of an intermediate leg 30, on the one hand, and a seat elevating leg 32 forming part of the seating facility 20, on the other hand, for elevating the trainer 10 above a base in promoting the simulation of a kayak type paddling action. In also referring to
In also referring to
The spacer 18, seating facility 20, intermediate leg 30, footplate facility 40 and guiding layout 22 together form a trainer core assembly 28.
In addition to permitting slidable adjustment the foot abutment plate 42 in being fitted with the heel rest 44 and the toe strap 46 is also vertically as well as swivelable adjustable by way of a vertical adjustment mechanism. In referring more particularly to
As regards swivelable adjustment and staying with
The extent of the paddling simulation effect as brought about by the frictional sliding of the cord 14 along the pole 12 and supplemented by the expansible retraction of the spring 24 within the spacer 18 once the trainer 10 is in use is adjustable by way of an adjusting mechanism involving an adjusting line 74 extending within the spacer 18 that extends from the end of the spring 24 remote from that to which the cord ends 14.3, 14.4 are secured. The end of the line 74 passes though the wall of the spacer 18 in close vicinity of the seating facility 20. The end region of the line 74 beyond its location of egress is fitted with a locking item 76 for adjustably holding the inner end of the spring 24 at a fixed spacing in relation to the seating facility 20. An increased tensioning effect on the spring 24 as brought about by its retraction by way of its inner end in the direction of the seating facility 20 by means of the line 74 has the overall effect of increasing a paddling simulating effort and vice versa.
The paddling action as performed a kayaking user involves a natural sideways rocking of the vessel. Such rocking effect is also incorporated in the design of the trainer 10. In again also referring to
The cord guiding layout 22 comprises cord end region supplementary friction generating means in the form of guide bushes 88 that are laterally adjustably fitted to a guide carrying rod 90 in turn fitted to a guide bush elevating formation 92 fitted to the end of the spacer 18 remote from the seating facility 20. The bushes 88 perform their supplementary friction generating effects once the trainer 10 is in use in the cord end regions 14.3, 14.4 sliding to-and-fro there along on tensioning and retraction of the spring 24.
The trainer 10 includes a pole storage facility as provided by pole accommodating notches 94 respectively formed within the leg 30 and the formation 34.
In preparing for use in performing a kayak simulating exercise and also referring to
Once desirably set a kayak paddling simulating routine is done by performing a paddling action by way of the pole 12 that is thus conventionally kayak paddle fashion gripped by both hands about it centre with the pole 12 at the outset extending transverse to the spacer 18, as shown in
During a conventional kayak paddling action the user of the equipment does not retain a stationary upper torso position within the equipment but also performs forward and rearward torso displacements. Similarly the user of the trainer 10 also performs forward and rearward torso displacements during a training routine. Such displacement actions alternatingly cause the free end regions 14.1, 14.2 of the cord 14 to by way of to-and-fro actions slide along the guide bushes 88 creating a supplementary friction effect in supplementing the friction effect of the cord along the pole 12. The to-and-fro movement of the opposite sections of the cord 12 are furthermore reflected in successive expansion and contraction cycles of the spring 24 that introduce successive relaxable tensioning actions that also supplement the friction generating effects of the cord 14 along the pole 12 bushes 88.
In simulating such conventional kayak paddling action the sideways rocking that is associated with an actual paddling action is accommodated by the rocking layout in response to the rocking effect of the lateral rocking formations 78 in their slots 80.
The overall effect of the friction in combination with the relaxable spring tensioning actions thus simulates the drag on paddle blades as urged along water during a conventional kayak paddling action having the overall effect of the trainer 10 being employable in a kayak paddling action simulating routine.
It is an advantage of the invention at least as specifically described that the trainer makes use of uncomplicated means in utilising the frictional effect of a sliding cord along a pole as supplemented by the extensible contraction of a spring to simulate a paddling effect through water while also simulating the natural rocking effect found in actual kayaking which enables trainer user to train such person's balancing skills away from a body of water.
