Abstract

Said skate comprises a support part (1) carrying a weight device (3) and a footrest (5). It can move along the ground or slide along a rail. It is used with disk-shaped weights having a central hole, of the type sold in shops (4).

Description

The invention relates to apparatus for weight training of the upper and lower limbs, for gymnastics, physiotherapy, and medicine.

The characteristic of the invention consists in sliding in a rigorously horizontal plane, along one or two slides, in a back and forth movement, one or two weight carriers with progressive load - the weight carriers for the members lower are weighted footrests, for the upper limbs of the weighted handles - and a locking device on each slide.

We know different devices, such as rowing devices, which include a sliding seat on slide and fixed footrests; they have the disadvantage of causing low back pain and not to offer a progressive effort for the lower limbs.

The present invention aims to remedy these drawbacks.

The invention as characterized in the claims solves the problem by fixing in a horizontal plane the slides on which the weight carriers move. This has the consequence of eliminating the effect of gravity: weights n '' never carry the weight carriers on the slides.The advantage of movement in a horizontal plane is that the joints are not subjected to the force requested by the weights: they do not risk being injured.

The effort requested by the weights is identical for the flexor muscles and the extensor muscles: the invention is a bodybuilding device for all the muscles of the members used.

The exercise of progressive strength is ensured by increasing the number of weights.

For the lower limbs, the invention consists of a support, one or two slides, one or two weight footrests, a locking device, and a stationary seat.

The two support bars have a section and a length sufficient to ensure the construction and the stability of the apparatus during the exercise.

They must be strictly of the same height, their widths can be different for the needs of construction.

They are laid parallel to the ground and sufficiently spaced so as not to limit the use of the slides over the length defined below.

The two identical slides, fixed on the top of the support bars, are wide enough to ensure the correct and rapid movement of the footrest at maximum laden weight.

They are long enough to allow a person seated in the seat with their feet in the footrests to fully extend their legs. Their spacing is such that the person's legs are parallel.

The seat is attached to one end of the device above the rails.

A device allows you to adjust the height: two vertical rods on which slides the seat fitted with slides. Pins or other locking device, on each rod, allow to fix it.

The characteristic of the invention is the weight footrest.

The weight footrest includes a rectangular carriage, the width of which is adapted to that of the slide. It is fitted with rollers or the like to slide freely and quickly.

The trolley carries the sole and the weight device of the footrest.

The sole fixed on the width of the carriage, and arranged at one of its ends, is inclined on its support, relative to the vertical, so that the foot is in flexion, without being perpendicular.

It is made of a very rigid material so as not to bend, and it is rectangular in shape. Its dimensions are such that the foot is comfortably installed.

The sole has a rounded and anatomical structure in its lower part, the function of which is to support the heel. It also has a fairly wide and adjustable strap to hold the foot in place.

The weight device of the footrest consists of a transverse plate which connects the two sides of the trolley and is wide enough and resistant to carry the weights.

It is sufficiently distant from the sole, to allow the placement and removal of the weights. In its center is fixed vertically a cylindrical tube, long enough to receive a series of weights. The section is sufficient for the maintenance and donning of the weights .

A clamp or other clamping device is provided to hold the weights in place.

The disc-shaped weights pierced at their center are used, which are commercially available.

Another non-limiting variant of the weight device: the weight box.

The weight box has a trapezoidal shape because of the inclination of the sole which is supported there.

Its dimensions are such that the large base corresponds to the surface of the trolley behind the sole, and the small base to the surface of the trolley bounded by the vertical plane passing approximately through the upper edge of the sole. Its height is sufficient to maintain the weights in place.

 It is built in rigid material, and fixed on the trolley behind the sole and against it.

 I1 is intended to receive weights of cubic or parallelepiped shape which can be arranged vertically and under the sole horizontally.

The two variants of weight carrier: the device using the disc-shaped weights and the weight box using weights in the shape of a parallelepiped or cube, are applicable to the weight handle.

The coupled mechanism of the slide and the trolley allows the user, seated on the seat, feet in the footrests to exert a rapid, continuous movement of the legs, without resistance, for a long time. The legs are alternately or jointly folded or stretched.

The invention is characterized by a locking device on each slide.

The blocking device includes: - a rule whose section is sufficient to act as a stop at
weight footrest, the length of which adapts to the width of the
slide.

- two slides, fixed on the same side of the rule, one at each end
and - a tightening button or other device, in the center of the rule, to
move and fix it in the desired location.

The function of the blocking device is to allow the control of the leg bend.

As a variant, this device is presented in different versions.

The invention is a device made according to the previous model, but the two slides are no longer parallel. They deviate obliquely from the median axis of the support.

On the support opposite the seat, they are fixed apart and on the support of the seat, they are fixed close together. The support bar opposite the seat is long enough for the spacing of the slides to correspond to a position of the feet well apart.

The advantage of this device is to exercise the abductor muscles of the lower limbs and the hip joint.

The invention is an apparatus which combines the possibilities of the two preceding apparatuses: the slides can be oblique or parallel with respect to the median axis of the support.

They are fixed by means that allow their angular displacement.The support bar opposite the seat has a groove over almost its entire length.The part of the slides which is on the side opposite the seat, also has a groove, in the direction of the length, which is located above the groove of the support bar, and which is long enough to allow the locking device to follow the movement of the slide. The grooves of the support bar and the slides are of the same width.

A locking device on each slide connects the grooves to the support and allows movement and locking of the latter. Intermediate positions are possible.

The blocking device is also a safety device, the slides fixed for the exercise must absolutely not move.

On the support bar that supports the seat, two vertical axes are symmetrically fixed on either side of the center line of the support, at a distance that allows the slides in parallel position to be slightly apart. at the locations corresponding to the axes, rotate around these axes during angular movement. Each has a locking device that eliminates the vertical and horizontal vibrations that can cause the exercise.

A device fixes the stationary seat and adjustable in height above the pivot axes.

This device, the most complete in the range, allows personalized and progressive training.

The invention is an apparatus with a slide for both feet.

The slide is wide enough to carry a weighted footrest on which both feet can be placed. The legs practice together.

The weighted footrest is equipped with a sole with two structures for the heels, and two fixing straps, placed so that the feet are slightly apart.

The weight device of the footrest is more important than in the three preceding devices and allows a heavier load.

The dimensions of the locking device are adapted to the slide.

Advantages of the invention for the lower limbs: - maintenance and bodybuilding of all the muscles of the Leg.

- softening of the knee joint with improvement of 1 '
amplitude of the fold.

- respect for the integrity of the joint and in particular the
patella.

- maintenance of the abdominal muscles.

- maintenance and rehabilitation of the hip joint for patients
like i oblique slides.

All the devices of the invention can be made foldable for easy storage.

The folding of the devices is obtained by a system of free points and pins, or other locking device. The free points in rotation at the four fixing points of the slides on the support bars allow the sliding of the latter under the slides: the appliance is in the closed storage position.

The pins or other locking device ensure the stability of the device in the open exercise position.

The folding system described is a particular form of the invention and is not limiting.

The invention is an improvement to the rowing machine.

In this case, the rowing device is completed with a seat and two weight footrests mounted on carriages which slide along two parallel slides. By means of pins or other locking device, the seat and the two rests -weight feet are alternately free -or immobilized depending on the exercise you want to practice.

The invention will now be described with the aid of diagrams, given by way of example, without limitation.

Figure 1 is a schematic representation of the weight machine with two parallel slides.

In Figure 1, we see the two support bars 1 and 2, the lengths of which are sufficient to ensure the construction and stability of the device during the exercise. Their heights are strictly identical so that the slides are in a plane horizontal. 0 we see that the support bars are placed parallel to the ground.

One 1 is at the end of the construction to leave the longest run to the slides, the other 2 is halfway across the seat.

The two identical slides 4 fixed on the support bars 1 and 2 are wide enough to move the footrests by weight. Their length allows a person sitting on the seat, feet in the footrests, to lengthen the legs; their spacing is such that the person has parallel legs.

The seat 5 is fixed on the runners 4
In the diagram we see the weight footrests 6 and the locking devices 7.

In Figure 2, we see the rectangular carriage 8, built to adapt to the width of the slides 4, we see the housings 9 for the rollers (not drawn) or other device. On the carriage, the sole 10 is manufactured in a rigid material so as not to bend; it is inclined with respect to the vertical, so that the feet are in flexion position, without being perpendicular. In its lower part, we see the structure ll rounded and anatomically shaped to support the heel .

An adjustable strap 12 adjustable and wide enough to hold the foot in place.

Behind the soleplate is the weight device 13, the transverse plate 14 of which connects the two sides of the carriage, is fixed in such a way that the inclination of the soleplate does not interfere with the placement and removal of the weights. center 15 is fixed vertically a cylindrical tube 16, intended to receive a series of weights. Its length and its section are sufficient for the threading and the support of a series of weights.

Weights 17 are used in the form of a disc pierced in their center which is commercially available.

A clamp 18 keeps the weights in place.

FIG. 3 shows a rule 19, the length of which adapts to the width of the slides 4, and the cross section of which is sufficient to serve as a stop for the weight footrest.

Two slides 20 arranged on the same side, allow the device to slide on the slides. A tightening button 21 in the center of the rule allows the displacement and the fixing of the tightening device.

FIG. 4 shows a carriage 8, with the housings 9, the sole 10 with the structure 11 and the fixing strap 12. The sole identical to that of the weighted footrest of FIG. 2, is pressed against a box 22 of trapezoidal shape. The large base 23 is equal to the surface of the trolley behind the sole and the small base 24 to the surface of the trolley bounded by the vertical plane passing approximately through the upper edge of the sole. The height 25 of the trapezoid is sufficient .te to maintain the weights.

The weight box is fixed on the sides of the trolley and against the sole. The weights used have a rectangular or cubic shape (not drawn) which can be placed vertically 26 or horizontally 27 under the sole.

In Figure 5, we see the support bars of the same nauteur, one 28 opposite the seat is longer than the other 33, to allow the position of the feet well apart. It has a groove 29 on almost its entire The slides 30 each have a groove 31 on the part opposite the seat, which is located above the support bar 28, and which is long enough to allow the locking device 32 to follow the movement of the slide. two grooves 29 and 31 of identical width are connected by a locking and safety device 32. On the support bar 33, we see the vertical axes 34 placed symmetrically on either side of the center line of the support, to a distance, which allows the slides in parallel position to be slightly apart.

The slides fitted on the axes 34, pivot according to the angular displacement. A blocking device 35 eliminates the vertical and horizontal vibrations which the exercise can cause.

We see the seat 36 fixed above the axes. The weight footrests 6 and the locking device 7 shown schematically on the slides.
