Description

"FLOATING ERGOMETRIC REMOTE WITH PROPELLER".

This report refers to a patent for a floating propeller rowing exercise which, through an innovative concept of self-propelled mobility, provides the user with an added attraction in the practice of rowing exercise simulation.

In fitness centers there are gadgets titled "rowing" that keep the user sitting on a sliding mobile bench with 10 foot support in the same body position that a normal boat would require. The hands, instead of side oars, hold the end of an unsupported handle whose center receives a forward-moving cable or rope to the axis of a user's pull-resistance mechanism.

Rowing appliances, conventionally

well-known, they are gym equipment that allows physical training simulating rowing. Overall, gyms seek to provide a healthy and aesthetic environment to compensate for the immutability of the landscape. However, in order to meet the spaces available in the gym, they make these equipments available in a condition of proximity and parallelism that becomes.

In order to eliminate this inconvenience, the patent application in question features an innovative floating exercise rowing mode that places the user in the water and sends the rowing athlete back to their natural environment, but exercising their arms, trunk and legs. in a mixed exercise, aerobic and at the same time perfect bodybuilding. The device uses the user's energy to pull the equipment over the water.

These and other objects and advantages of the present invention are achieved with a propeller floating ergonomic paddle comprising a rectangular structure on which the components of a traditional gym ergonomic paddle are mounted, with its front and rear displaceable seat, supported by for the feet, and a bar with handles, which through a rope attached to the bar transmits and offers pull resistance for the desired cardiovascular exercise. According to the invention, said structure is fixed on the boat hull, which makes it floating; the structure and hull assembly being pulled on the water by means of a propeller, driven by gears mounted on a shaft in turn mounted by bearings on the frame crossbar, the latter having in the front two columns, provided with bearings on top, where a transverse axle is mounted, with an integral central traction pulley and next to it, a pulley mounted to the axle through a roller ratchet.

In the following, the present invention will be described with reference to the accompanying drawings in which:

Figure 1 is a plan view of the floating propeller rowing machine;

Figure 2 represents a vertical section

longitudinal of the floating propeller rowing;

Figure 3 is a longitudinal section, in detail, of the traction mechanism of the propeller floating ergonomic paddle; and

Figure 4 is an elevation detail of the floating propeller rowing traction mechanism;

Figure 5 is a plan view of the

traction mechanism illustrated in the previous figure; and

Figure 6 is an elevation view of the traction mechanism shown in figures 4 and 5.

According to these illustrations, the propeller floating ergonomic paddle 10, object of the present invention, is comprised of a lightweight, basic rectangular shaped structure 1 which is fixed on a boat hull 2 and has two columns at the front 3 , on top of which are mounted two bearings 4, which receive a horizontal axis 515, transverse to the frame 1.

In the middle part of the structure 1, four brackets 6 are fixed, which support horizontal and parallel tubes 7, which, through rollers, allow a seat 8 to slide back and forth.

Below seat 8 an extension is provided

9, facing downwardly holding at its end, a rubber band 10, which extends forward of the hull 2, where its end hooks to a pin 11 protruding down from the front of the frame 1, see figure 2.

According to figures 3 and 4, axis 5 is almost

center a pulley 12 of solidarity with it. In the same axis 5, next to the pulley 12, a pulley 13 is provided which secures the end of a rope 14, of such length that it allows the pulley 13 to make a few turns to end in a bar 15 with two hand grips for the user's hands. This pulley 13 is mounted to shaft 5 via a roller ratchet 16 so that it only transmits movement to shaft 5 when rope 14 is pulled.

The same sheave 13 has a spiral spring 17, the other end of which is attached to the column 3, which spring 17 forces the sheave 13 to rewind rope 14 as shown in FIG. 4.

Frame 1 at its rear has two

bearings 18, where a transverse shaft 19 is mounted, which centrally has a pulley 21 which, through a belt (chain) 22 receives the movement of the pulley 12 of the shaft 5, with shifting pulleys 23, 24 and 28, which make up the

mechanism transmission system.

On the same axis 19 of the pulley 21, a bevel gear 29 is attached, which connects to the other gear 30 and serves to reduce or multiply the rotation speed and change the direction of rotation, see figures 5 and 6.

A gearbox 27 serves to change the

axis of rotation has a shaft 31 connected to the bevel gear 30 which drives the bevel gear 32 which in turn drives the gear 33, whose axis 34 is already longitudinally of the float.

On this axis 34 a propeller 20 is mounted which

spinning determines the movement of equipment called the floating propeller rowing machine in question. The footrests 25 of the user's feet are close to the feet of the columns 3, and are articulated to the frame 1 by a vertical axis 26 fitted to a bushing to provide limited rotation of the footrests 25, which will drive right or left. On the left is the gearbox 27, where the propeller 20 does the work of a steering rudder, articulated by the bar 35 connected to two label terminals 36.

With this constructive design, the user sits on seat 8, and puts his feet on the supports 25. Flex the 10 legs and the seat 8 slides forward under the tension of the elastic 10, as illustrated in figure 2. It further promotes the movement of body forward, arms outstretched and grip bar 15.

The user now stretches the legs, and with that, the seat 8 moves backwards, the rope 14 being partially unwound from the pulley 13, producing a turn in which the ratchet 16 is engaged, turning the axis 5 and the pulley 12, which transmits its movement to the pulley 21 by means of the belt 22, passing by deviation pulleys 23, 24 and 28. The pulley 21 rotates and the axis 19, which causes the water wheels to propel the boat hull 2 in the Water. When the rope 14 rotates the pulley 13, it rotates one end of the coil spring 17, forming a torque on that pulley 13, such that the tendency to rewind rope 14 is present and occurs in any loosening of that rope.

Next, the user pulls the rope 14 further, contracting his arms and finally tilting his body back while still pulling the rope. The user returns to the starting position with the aid of elastic 10 to seat 8 and spiral spring 17.

The roller ratchet 16 does not allow the shaft 5 to receive counter-motions, and thus "freewheel" the transmission of the pulley 12 to the pulley 21, and thus the shaft

19 and the propeller 20 which is rotated by gears may continue to spin by inertia or by water reaction.

The gearbox 27, where the propeller 20 does the steering rudder work, can be driven by the footrests 25, which are pivoted on an axis 26, connected to a bar 35 through two label terminals 36.

The user walks in a lake, or a mirror of water, enjoying the breeze, the landscape, while practicing a cardiovascular exercise gym.
