Description

Multi-exercise weight training machine, based on the optimal dosing of the tensile forces applied at the level of two towers, for high performance training

Technical sector

The machine is part of the technical sector of high-performance devices, assigned to the sports domain (gyms), belonging to the health system (sports fans, post-traumatic physical rehabilitation) or Olympic clubs (professional athletes).

State of the art

Currently, within the sports sector, several models of machines are known, which use different mechanisms to transmit tensile forces and use them to strengthen the bone, ligament and muscular system, improving physical performance in various sports domains.

An important range of machines is represented by the group of multi-exercise machines, called ^" pulley towers ^" .

They are machines that, according to their name, allow you to perform several type exercises to improve the general physical state (combined exercises at the level of different muscle groups).

Used in the sports domain since the beginning of the last century, its technology has evolved continuously, with the purpose of improving the physical performance of any person, better dosing the effort and avoiding injuries.

They use several types of handles, to make a connection between the user and the device cable, which uses several pulleys to receive the tensile forces generated by the counterweight, represented by rectangular, metallic pieces of several kilos.

The machines are composed of several metallic elements, resistant (generally of iron or steel), that form an external structure, a skeleton, that serves as support for the elements that form the internal structure.

The external structure is constructed of tubes or metal bars (any type of profile, most commonly used being the rectangular ones), resistant to large loads (hundreds of kilos).

The skeleton (external structure), is formed by two towers placed with their long axis in a vertical and parallel direction, both towers presenting a base, a roof, and several pillars that connect the base with the roof.

Each tower is generally formed by several vertical pillars (oriented with the long axis in the vertical direction), and oblique-oriented, lateral pillars (each oblique-oriented pillar supporting one of the vertical pillars on the side face). Each of the pillars (vertical or oblique) has some way of coupling at one end with the base and the other with the ceiling. The coupling modes can be metal screws, direct welding, or both.

The base and the roof are metal frames, constructed of rectangular profiles, generally welded together, or mounted with screws, which are used for coupling with vertical and oblique pillars, forming a tower. The dimensions of the base (of the metal frame) are generally larger than those of the ceiling, to ensure better machine stability.

The two towers are connected to each other, at the upper level, by means of metal (one or two) sleepers, which are coupled at each end with a tower (metal screws).

In the central part of the sleepers, some machines have supports for solid metal bars (used to perform muscle elongation exercises, type dominated).

On each of the opposite faces of the two towers (oriented towards each other), supports are assigned to a metal guide tube, which has variable dimensions depending on each machine (generally longer than 1, 8 meters ), oriented with its long axis in the vertical direction.

The guide tube has a multitude of holes (horizontally), equidistant (a fixed distance, repeated, between two nearby holes), which pass through one face or two opposite faces (matching holes). A mobile support, with a rectangular profile, fits the guide tube and uses it as a sliding guide. The mobile support has a metal shaft that connects with parallel metal plates, forming a joint. The plates are free (without direct contact with the tube) and hold one or two pulleys, placed on the same plan, using screws. The screws pass through matching holes made on each metal plate and through the center of each pulley. The cable of the device enters the pulley system, belonging to each tower, through the mobile support that presents the metal plates. The mobile support has one or two lateral holes, coinciding with the equidistant holes made on the guide tube. When it is necessary to adjust the length of the cable, at the level of the pulley system of each tower, the athlete moves the mobile support in a vertical direction, at a level considered necessary to perform a certain type of exercise, and blocks it at the level of the guide tube by a wand, which passes through the matching holes of the support and the tube. The wand can be free in front of the mobile support (the oldest machines), or it can be fixed on it (by a welded nut containing an internal spring, forming a retractable device, which can act on any equidistant hole made on the tube). guide).

The internal structure of each tower is constituted by the other pulleys, coupled with the external skeleton by means of some supports of various designs (fixed by welding or with metallic screws), forming a system. The pulley system guides the metal cable (several meters long), from the handle (coupled with the end of the cable that exits the pulleys located on the mobile support) towards a solid metal bar. The metal bar has variable dimensions (generally about 500-600 mm in length and 30 mm in external diameter). The metal bar has a lug, which intermediate the connection between the cable and a counterweight (rectangular pieces), using a climbing carabiner. The rectangular pieces are located in the center of each tower (at the level of its base, frame), supported on springs (dampers) and held vertically by two cylindrical bars, vertical and parallel. The bars are generally metallic (iron or steel), solid, with an approximate diameter of about 30 mm and about 2000 mm in length (their dimensions may vary depending on the design of the machine) and serve as sliding rails for rectangular pieces.

The two rails are fixed, in the vertical direction, by various methods (screws or welding) at their ends, between the base and the roof of each tower.

The rectangular pieces, counterweights, are overlapping each other, forming a column. Each of the pieces has, from its upper face to its lower face, three holes of vertical paths, parallel to each other (a central hole and two other remote holes, lateral, one on the right and one on the left of the central hole ). For the rectangular pieces to follow a vertical path, each of the two cylindrical rails passes through one of the two vertical and lateral holes (described above), crossing each rectangular piece from its upper face to its lower face. To the indicated holes, another hole, central, of horizontal and perpendicular path is added on the long axis of each rectangular piece (oriented from its front face to its rear face), crossing almost its entire width. The diameter of these holes represents approximately one third of the thickness of each rectangular piece.

The bar with lug, has holes, horizontal, parallel to each other, equidistant, that cross its entire diameter. The size of these holes is the same with a third of the diameter of the bar with a lug. These holes allow the adjustment of the counterweight (the height of the column of rectangular pieces) that is selectively connected to the cable, using a very resistant metal wand (usually steel, approximately 200 mm in length and 10-12 mm in diameter ). When the wand is introduced at the level of the central hole of horizontal path (belonging to a rectangular piece) it blocks the entire column of pieces, located above it, coupled with the bar with a lug. Once the cable is pulled, through the middle of the handle, one or more rectangular pieces rise in a vertical direction. When the tensile forces cease, the pieces fall back into their initial position. When the column of rectangular pieces is in motion, between the two lateral vertical holes (made on the rectangular pieces) and the two cylindrical rails, significant friction forces appear. To reduce frictional forces, at the level of the vertical side holes and on the rails, industrial oils (engine lubricants) are used. In spite of using these lubricants, the friction forces do not decrease sufficiently so that the movement of the rectangular pieces on the two cylindrical rails is uniform. Therefore, the athlete needs to pay attention not only to their exercise, but also to dampen the vibrations generated in the machine by the forces of traction and friction, in the attempt to dose their effort and avoid injuries.

This mechanism has another series of drawbacks: 1) Rectangular parts can be used as a counterweight only in the device in which they are installed (they cannot be removed from the device efficiently, quickly, to be installed in the same training session in other machines); 2) cannot be used for bars or dumbbells (they are inert); 3) given a disproportionate height of the column of rectangular pieces versus the height of the towers (their roofs), they cannot be placed loads greater than 100-120 kilograms, in each tower, because when climbing, the column of pieces collides against the roof of the towers, blocking the optimal cable length necessary to perform certain types of exercises (represents an obstacle in increasing its muscle strength and may predispose to accidents, injuries); 4) the increase in the height of the columns of rectangular pieces (of the installed load) is carried out in a difficult way, with the additional addition of rectangular pieces adapted to the type of the machine.

Many machines on the market use systems of several pulleys, which do not allow an optimal adjustment of the length of the metal cable, which makes the connection of the handle with the column of parts. An approximate necessary length is about two and a half meters of free cable, measured between the initial and final position of the handle in front of the mobile support with articulated plates. In these machines there are many exercises, in which athletes are limited by their size, needing to improperly adjust their postures, performing the exercises inefficiently and increasing the risk of injury.

A multitude of current models have a standard configuration, designed for athletes with sizes up to about 1, 90 meters.

Almost all machines of this class have a structure based on the union of the two towers only by upper sleepers (often only a metal sleeper, rarely two). This way of anchoring, adds another series of disadvantages: 1) when making a single connection between the top of the two towers, they cannot avoid significant vibrations at the level of the apparatus, which leads, to an accentuated wear of the machine, by the mechanical force arms initiated at the vibratory moment; 2) for having a short distance (approximately 2.20 meters, between the floor and the upper sleepers), it does not allow effective elongation exercises (Olympic gymnastic type, exercises for muscular elasticity, stretching in hanging positions), for touching with the feet the ground when holding the device of the upper sleeper); 3) they have a lower stability when gripping the devices located on the upper sleepers, and do not allow adapting auxiliary machines to the same structure (paddle, leg bench, for pectorals, or for the shoulder) in a secure, fixed position; 4) do not allow effective work of several people simultaneously; 5) increase the need for adequate spaces for machines assigned to train different muscle groups (auxiliary machines cannot be added in the same area used by the apparatus); 6) the designs of the current machines present difficulties in adapting to higher loads compared to the standard values (below 120 kilos in the column of pieces), which implies a disadvantage for a professional athlete (runner, bodybuilder, fighter, etc. ), which will need to increase its strength (isometric or explosive); 7) In the standard design, the cable (when leaving from the mobile support), describes an oblique angle on the ground plan (horizontal), so that the actual load with which the athlete trains decreases, knowing the fact of that the maximum performance of an exercise is obtained by directly defeating the forces that are oriented in the direction of earth's gravity; 8) Due to the design deficiencies indicated above, the guarantee of these machines is quite limited (guarantees are offered for an approximate period of five to ten years, for the elements of external metal structure, skeleton, in the case of professional use) , and less for the elements belonging to the internal structure (generally two or three years); 9) need specialized technical assistance from of the company that has commercialized the machine, because the worn parts can be changed only by others, of the same brand (they are not found in hardware stores or in auto workshops), which implies an increase in the inactive period of the machine and additional costs for repairs, in case of deterioration.

In the following patent documents, solutions for the problems specified above are proposed: USD511189, USD4199139, USD4632388, USD4775146, USD4784384, USD4974838, USD5135453, USD5184992, USD6299568, USD6443877, USD6488612, USD6565490, USD291312129129129129129129129129129129121129129129129123129128 , USD7927262, USD650022.

In the industrial branch belonging to the sports sector, there are important general requirements for the continuous improvement of these machines, and therefore it would be desirable to find optimal solutions, to avoid the deficiencies mentioned above, to perform complete physical exercises, with an adequate dosage of the tensile forces implied by its mechanisms, obtaining an evident improvement of the physical performance of any person, in conditions of maximum security.

For this, the present machine focuses on solving the problems specified above, offering several advantages, so that any user obtains, in a fast and efficient way, better results in their training. All the characteristics of a machine of this class, necessary for optimum performance, will be evidenced in the descriptive part of this report, together with the accompanying drawings.

Machine description

The present description refers to a new weight training machine, multi-exercises, based on the optimal dosing of the tensile forces, by means of a characteristic system of pulleys and cables, which form a compact, safe and practical structure, offering the possibility to perform high standard workouts, to anyone, from beginners to elite athletes.

The machine allows maximum adaptability to any type of exercise, type weights, without the risks involved in the free lifting of the dumbbells or bars (classic or Olympic) with discs.

Each structural element of the machine, presents an applied cluster of several techniques, adapted to the mechanical forces, that would act in any type of training and exercise. Due to an increased resistance, the machine offers all the necessary guarantees for high performance exercises and maximum resistance in its use. Its reinforced structure is designed for very high loads compared to those that could be installed on its devices. It is indicated for professional use, gyms (conditions of professional use: intensive use for more than 14 hours a day).

Given the peculiar structure it allows attaching auxiliary machines, becoming a complete platform for any type of exercise.

Due to its resistance and stability, it can serve as a support for several sports accessories (boxing bags and other tools of the same class, elastic ropes), allowing you to perform bodybuilding exercises, in various stress regimes (static and dynamic). The elements are completely removable, allowing access by any door of standard dimensions (dimensions: height 2 meters and width 1 meter).

It has an external structure (skeleton) and an internal structure, both formed by metal elements, joined together by welding and metal screws with nuts, making a set of very high reliability and resistance.

Its external structure is formed by two towers, joined together by four horizontal sleepers (two lower and two upper). The lower horizontal sleepers serve as horizontal sliding guides, supporting and blocking a central, mobile ramp. The upper horizontal sleepers fix several elements: two horizontal stair type structures, a system of elongation bars, a reinforcement system represented by two large plates of thick sheet, elongation rings with chains and supports.

The internal structure of each tower is formed by a cable that uses a system of several pulleys as a guide, to selectively connect with two mobile ramps (upper or lower-greater), overlapping one on top of the other in a vertical plane, which slide over two cylindrical bars, parallel to each other and vertical (used as rails), and damping springs (compression springs) located on the lower end of each rail. Most of the elements of the external structure are rectangular in shape, although this structure could be constructed from any other type of profile and material that can withstand high loads (cylindrical, triangular etc.).

The two towers are placed in parallel (opposite diametral), on the same support plane, and with the long axis in a vertical plan. Each of the towers has six vertical and two lateral (oblique) pillars, joined at its ends by two horizontal platforms, anchoring, one upper and one lower (base, respectively roof). One of the two lateral pillars (of each tower) has several equidistant and parallel holes, practiced on two opposite faces. Every two equidistant holes are coincident, oriented in the direction of an imaginary axis of oblique path on the long axis of the lateral pillar. Each pair of holes is used to fix a bar, used as a support for some discs (weights). Four of the vertical pillars have a support function and, together with the two lateral pillars, increase stability and serve as support for all machine structures. Two other vertical pillars are placed in parallel, on the midline of the opposite faces of the two towers, operating as sliding guides and fasteners, at different levels, for two mobile pulley supports, belonging to the internal structure, which allow you to adjust the length of a metal cable.

Between the base platform and roof, two cylindrical, metal, vertical and parallel bars are fixed. The two bars are used as sliding guides for two horizontal ramps (upper and lower), overlapping one on top of the other. Each ramp (upper or lower), has a central, fixed, metallic axis, which allows the placement and clamping of one or several discs (weights). Each of the central axes connects selectively with a tubular adapter. The tubular adapter connects through a carabiner (climbing type) with a metal cable. The cable belonging to the internal structure is connected at one end with a handle and at the opposite end, with the carabiner.

Compression springs are placed on the lower ends of each cylindrical rail, which dampen and prevent the impact of the ramps (upper and lower) with the base platform of each tower.

The two lower horizontal sleepers, serve as a sliding and anchor support for a central sliding ramp, mobile, divided in a central part and two lateral parts. The central part contains a system with a folding pulley, a metal plate fixed on two rectangular profiles, sliding along with its resistance elements (longitudinal and transverse). On each side, the central ramp has wheels (two transverse and two lateral), two lateral supports fixed perpendicularly on rectangular sliding elements, a horizontal rectangular rail provided with equidistant holes, two sliding cubic supports, four rectangular articular elements and one Accessory plate, mobile, with a retractable handle. The margins of the central ramp are covered by a damping frame (anti-shock).

On each upper crossbar (its side face), a longitudinal plate of thick plate is fixed

(thick metal sheet), which serves as a guide for two sliding supports, which hold elongation rings through the middle of two chains, allowing to regulate the distance between them. Above the upper horizontal sleepers are two removable metal ladders. Each of the stairs it presents two lateral support elements, which fix it on the upper horizontal sleepers. Each two lateral elements fix four tubular steps, in parallel.

FIG. 2: presents a top view (plan) of the machine, with several structures placed on the upper horizontal sleepers.

FIG. 3: presents a bottom view of the machine, with the bases of the towers, connected by the two lower horizontal sleepers, parallel to each other.

The machine is constituted by two towers placed in parallel, with their long axes oriented in a vertical direction, perpendicularly on the ground. The two towers are connected by two lower horizontal sleepers 9 and two upper horizontal sleepers 59. On the lower sleepers 9 a central, mobile ramp is placed. On the upper sleepers 59 there are several structures that allow stretching exercises (elongation) muscle.

The machine can be built at any scale, although there are dimensions considered optimal, which can be adapted appropriately, depending on the size of the athlete (from 1, 20 m to 2.30 m high): length 4.5 meters (measured from the furthest points of the base platforms of the towers), height 2.5 meters (measured from the ground to the highest point of the machine) and width of the base 2 meters (measured between its farthest ends).

The profiles used for the external structure of the machine, can be rectangular tubes (sides of the rectangle of 80 mm and thickness of the material 7 mm), of iron or steel.

FIG. 4, FIG. 5 and FIG. 6: present a front view of a tower, with the upper horizontal sleepers 59, sectioned.

The external structure (skeleton) of the tower is constructed of rectangular tubes, although the construction profiles can have any other shape (circular, ovoid, triangular, open profiles, etc.).

The two towers are placed in parallel, on the same support plane, and with the long axis in a vertical plane. Each of the towers has two lateral pillars 4, four vertical pillars 5, an external vertical rectangular rail 12 and an internal vertical rectangular rail 15, joined at its ends by two horizontal, anchoring platforms, one lower 1 and one upper 55 ( base, respectively roof).

One of the two lateral pillars 4 (of each tower) has several equidistant and parallel holes, practiced on two opposite faces. Every two equidistant holes are coincident with the direction of an imaginary axis, with an oblique orientation on the long axis of the lateral pillar 4. Each pair of holes is used to fix a solid bar 13, of iron or steel, used as a support for about 16 discs (weights). The vertical pillars 5, the lateral pillars 4 and the vertical rectangular rails (external 12 and internal 15), have a support function, increasing stability and multiplying the resistance to very high loads compared to the usual ones (500 kilos in each tower). On one of the vertical pillars 5 that form the back of a tower, an external support 6 is fixed. The external support 6 is fixed on the side face of a vertical pillar 5 by welding or nuts. It has a semicircular prismatic, placed horizontally, provided with a central hole. Through the central hole passes a hollow metal bar that serves to support two adapters, large 30 and small 31.

The two rectangular vertical rails 12 and 15, are placed in parallel, on the midline belonging to the two opposite faces of the two towers. The rectangular vertical rails 12 and 15, function as guides and fasteners at different levels, for two mobile supports of pulleys 49 and 52.

The entire structure of the machine uses high strength joining surfaces, represented by triangular joining elements 10, obtained by the section in two directions on a rectangular tube. One of the cuts has an oblique direction, at 45 degrees, in front of the longitudinal axis of the tube, and the other from the origin of the first, practiced perpendicularly on the same longitudinal axis.

A tower presents at the base level, a rectangular frame, base platform 1, with two lateral extensions, lateral foot 2. At the far end of each lateral foot 2, the lower bipod foot 3 (belonging to the lateral pillar is attached) 4), by means of an external structural screw 7.

The external structural screws 7 are metal shafts provided with threads, generally metric.

On the base platform 1, several triangular joint elements 10 are welded. The triangular joint elements 10, perform the anchoring at various levels, ensuring the resistance of the external structure (skeleton) of the machine. Each triangular joint element 10 has a central hole in its face, which allows the passage of an external structural screw 7. The structural screws 7 can be made of steel (calibrated steel screws with a smooth and long neck).

On the upper surface of the base platform 1, at the level of each angle of its frame, the triangular connecting elements 10 are arranged in anchor groups.

The anchor groups located at the level of the base platform 1 are of two types: anterior and posterior.

The anterior anchoring group, located towards the anchoring opening 8 (see FIG. 13B), is formed by three triangular connecting elements 10 and a flat tripod 17. Two of the triangular elements 10, have the perforated faces oriented in two planes perpendicular, one on the other, and welded on the base platform 1. One of the two triangular connecting elements 10 is connected by its perforated face, by means of an external structural screw 7, with the flat tripod 17. The other element of triangular joint 10 welded on the base platform 1, is coupled, using another external structural screw 7, with a triangular joint element 10 welded on the surface of one of the ends of a lower horizontal sleeper 9.

The rear anchoring group is formed of three triangular joining elements 10 and a flat tripod 17, placed on the surface of the rear angle of the base platform 1. The rear angles of the base platform 1, are located near the origin of the side foot 2. The three elements of triangular joint 10 are welded on the base platform 1. Two of the triangular joint elements 10 have opposite perforated faces, and connected by an external structural screw 7 (see FIG. 13A). The third triangular joint element 10 has the perforated face perpendicular to the triangular joint elements described above. An external structural screw 7 connects it with a flat tripod 17.

In each of the two anchor groups described, the holes located on the opposite faces of each two triangular joint elements 10 are coincident, but in a different plane compared to the other holes belonging to the elements of the same group (FIG. 13A and FIG. 13B), allowing the passage of the two structural screws 7, without intersecting.

A flat tripod 17 represents is an anchoring element. In the same plane it has three branches: two lateral and one vertical. Each branch has a hole in its center. The vertical branch of a flat tripod 17 is connected to a triangular joint element 10, by an external structural screw 7. The lateral branches are connected to the external face of the base platform 1, also using structural thymes 7, which pass through holes in the platform. The vertical pillars 5 are fixed on the base platform 1, by means of the anterior and posterior anchor groups. The fixing of each vertical pillar 5 is carried out by four holes made in each end thereof. Each of the faces of the vertical pillar 5, have a hole coinciding with the opposite face. The holes of each two opposite faces allow the passage of an external structural screw 7, for the union with the elements belonging to one of the anchoring groups.

On the front face, the base platform 1, is provided with two triangular joining elements 10, welded. Each of the triangular connecting elements 10 is connected to the flat tripod 17 by a side branch of its own, using an external structural screw 7. In this way, the anchor opening 8 is formed, for connection with one of the ends of the horizontal bottom sleeper 9.

In the previous part, the base platform 1, has an external basal support 11. The external basal support 11 serves as an anchor, for an external vertical rectangular rail 12. The external vertical rectangular rail 12, serves as a sliding guide, in vertical plan , for a pulley support 49.

On the base platform 1, on the opposite face in front of the external basal support 11, an internal basal support 14 is fixed, which fixes an internal vertical rectangular rail 15. The two rectangular vertical rails, external 12 and internal 15, are placed flat vertical, parallel The internal vertical rectangular rail 15 serves as a sliding guide, in a vertical plane, for a pulley support 52. The external vertical rectangular rail 12 and the internal vertical rectangular rail 5, together with the lower horizontal sleepers 9, have a multitude of equidistant holes 47, central. These holes cross two opposite faces of each rectangular vertical rail (12 and 15) and of the lower horizontal sleepers 9. The equidistant holes 47, allow the blocking on the rectangular rectangular rails, 12 and 15, of the pulley supports, 49 and 52 respectively, at different levels. The blocking for the two pulley supports, 49 and 52, is carried out using two identical screws, 49C and 52D. Each of the two thymes, 49C and 52D, makes the blocking of the two pulley supports 49 and 52, when they pass through holes 49B and 52E, together with the equidistant holes 47. Modifying the position, in a vertical plane, between the two pulley brackets, 49 and 52, the length of the main cable 34 can be adjusted, for the needs of any exercise and height of the athlete. The external vertical rectangular rail 12 is fixed on an external upper support 43. The external upper support 43 is fixed, by means of its two fixing plates 44, with two vertical pillars 5, which form the front part of the tower. The fixing plate 44 is made of thick metal sheet (15 mm thick), having an inverted ^" L ^" shape, in an antero-posterior view.

The internal vertical rectangular rail 15 is fixed on the rear face of the two vertical pillars 5, located on the front face of the tower, through the inner upper support 45. The inner upper support 45, is connected by the intermediate of its fixing plates 46, on the rear face of the same vertical pillars 5.

In the center of the base platform 1, a lower support 18 is coupled, by means of two fixing plates 57, welded perpendicularly on its ends. The fixing plates 57 are coupled on the base platform 1 by means of external structural screws 7.

Two vertical holes 19, parallel to each other, are made perpendicularly on the surface and in the vicinity of the two ends of the lower support 18. Between the walls of the vertical holes 19 and the lower ends of the vertical cylindrical rails 21, tubes are interposed of rubber (not indicated in the figures), which dampen vibrations. The lower support 18 blocks the lower ends of the vertical cylindrical rails 21 at its level.

A support with similar structure, upper support 56, is placed in the center of the roof platform 55, and fixed at its ends by two other fixing plates 57. The fixing plates

57 are connected to the roof platform 55 by means of external structural screws 7.

The structural difference between the lower support 18 and the upper support 56 consists in the presence of two auxiliary ears 58, welded on the lower face of the upper support 56. Each auxiliary ear

58 is welded at half the distance between a hole 19 and a fixing plate 57. The auxiliary flaps 58 are connected with an auxiliary cable 37 by means of climbing carabiners (not numbered in the figures, smaller and of similar design with a climbing carabiner 33). The auxiliary cable 37 has at the opposite end an identical carabiner with the carabiner installed on the auxiliary ear 58, which allows it to connect with the ear 36, welded on the upper ramp 35.

The two supports, lower 18 and upper 56, block in vertical plane, the two vertical cylindrical rails 21. The vertical cylindrical rails 21 are bars of calibrated and rectified steel, 30 mm in diameter, which serve as a uniform, flat sliding guide vertical, for two ramps, lower 22 and upper 35.

On the base platform 1, surrounding the lower end of each cylindrical rail 21, a compression spring 20 is placed, which has two washers, one at the top and one at the bottom. The washers (not indicated in the figures), perfectly fit the cylindrical rails 21 at the mentioned level, without allowing the central axis of the compression spring 20 to present deviations from its initial position, in the necessary damping for the fall of the ramps , bottom 22 and top 35.

The two ramps, lower 22 and upper 35, have an aerodynamic design, and rounded contours, to facilitate the placement of the disks 16 and avoid accidents at the time of exchange. Each one presents in its center a bar, central axis inferior 25 or superior 39, that support the discs 16 (classic or Olympic). Each of the central axes 25 and 39, are welded at their lower ends to a central hole that crosses one of the ramps, lower 22 or upper 35, in the vertical direction. This design offers maximum resistance to disc loads 16 on the ramps.

The lower central axis 25 is a solid, 1 meter long, 35 mm diameter steel bar. The upper central axis 39 is a steel tube, 30 centimeters long, 30 millimeters outside diameter, 20 millimeters inside diameter. Each of the two central axes, 25 and 39, have a coupling hole 27, with a horizontal, central and perpendicular path on them, which crosses them along its entire diameter, near their upper ends.

To slide on the vertical cylindrical rails 21, the ramps, lower 22 and upper 35, have tubular sliding elements 23 and 38 (fixed by welding) at the level of their ends. The tubular sliding elements 23 and 38 are profiles partially closed at the lower end by washers (not indicated in the figures), welded in a horizontal plane, perpendicular on the long axis of the tubular elements. The washers are provided with central holes of a larger diameter (with a few millimeters) compared to the external diameter of the cylindrical rails 21.

The tubular sliding elements, 23 and 38, have an internal diameter that allows the introduction of several bearings 24, overlapping one over the other, in a vertical direction. The bearings 24 are linear (axial) type bearings. An axial bearing is a tubular shaped bearing, which has a multitude of spheres on its inner surface, which serve to perform a uniform sliding on a central axis (bar), reducing frictional forces. The tubular sliding elements 23 and 38, have at their upper ends other detachable lock washers (not indicated in the figures), which prevent the exit of the bearings 24, when the ramps 22 and 25 move vertically on the cylindrical rails 21.

The ramps, lower 22 and upper 35, use the holes 27, to engage with the tubular adapter 26, through the middle of a fastener 32. The fastener 32, is a screw with the head and cross-shaped nut, favoring its design a rapid exchange of tubular adapter 26 between the two ramps, 22 and 35.

The tubular adapter 26, is a steel tube, with the thickness of the material of 6 millimeters, 150 millimeters long, with the inner diameter adapted to the outer diameter of each of the central axes 25 and 39. The tubular adapter 26, presents a connector hole 28, perpendicular on its long, central axis, crossing its entire diameter. The connector hole 28 is identical and coincident with the coupling hole 27, making the connection between the tubular adapter 26 and the two central axes, lower 25 and upper 39, through the intermediate of the fastener 32.

The adapter 26 has a high-strength connecting lug 29 at the top, assigned to a climbing carabiner 33. The carabiner 33 connects with the main cable 34. In this way the selective connection between the main cable 34 and one of the two ramps, lower 22 and upper 35. The central axes, lower 25 and upper 39, can be used, directly, for the support of several discs of classic design (central hole approximately 30 mm diameter), not indicated in the drawings.

To adapt to the central hole belonging to Olympic disks 16 (the diameter of the central hole of the disc is 51 mm) adapters, large 30 and small 31 are used. Adapters 30 and 31, can be nylon tubes. The large adapter 30 is 90 centimeters long, and the small adapter 31 is 20 centimeters. They have the internal diameter adapted to the external diameter of the central axes 25 and 39.

In its initial position, the lower ramp 22 is located on the two compression springs 20, and the upper ramp 35, supported on the central axis 25 and connected to the main cable 34.

The vertical cylindrical rails 21 are blocked, at the level of the roof platform 55, by fixing shields 60. The fixing shields 60 are coupled by means of screws (not indicated in the figures), which pass through path holes vertical practiced on the upper horizontal sleepers 59.

On the two vertical rectangular rails, external 12 and internal 15, the upper horizontal sleepers 59 and the roof platform 55, a system of six pulley supports is fixed (see FIG. 16A, FIG. 16B, FIG. 16C and FIG. 17 ). Four of the pulley supports, 50, 51, 53 and 54, are fixed (they are connected by screws to the tower structures), and two are mobile 49 and 52.

The pulley supports 49 and 52 are movable, using the rectangular rectangular rails, external 12, respectively 15 as sliding guides.

The support 49 is formed by an external sliding support 49A having on its faces locking holes 49B, a self-locking screw 49C, two handlebars 49D, two rotary supports 49E, a rotating shaft 49F, two support plates pulleys 49G and two nuts 49H.

The sliding support 49A uses the external vertical rectangular rail 12 as a guide.

The support 49A has two pairs of locking holes 49B, practiced near their ends, which pass through two opposite faces. The holes 49B allow an effective locking of the sliding support 49A at any level of the external vertical rectangular rail 12, by means of a self-locking screw 49C. A self-locking screw is a threaded metal shaft, which has a metal bushing, fixed directly by welding or by means of a nut on a support.

It has retractable capacity, by placing a spring inside the bushing, coupled to the screw shaft. A handlebar 49D, rectangular in shape, is welded on each side face of the support 49A. The handlebar 49D, facilitates the handling of the pulleys support 49, in vertical plan, to make an optimal adjustment of the main cable 34. The sliding support 49A, presents on the front face, at the level of its upper and lower ends, two 49E rotating supports soldiers The 49E rotary supports are arranged in a horizontal and parallel plane, presenting a circular bearing centrally (not indicated in the figures). A circular bearing has two or more concentric rings, which allow the insertion of spheres or cylinders between each two rings. They allow a uniform rotational movement (multiple of 360 degrees), reducing friction forces. A rotating shaft 49F passes through the two rotating supports 49E. The 49F rotary shaft is locked on the two bearings by nuts 49H. On the 49F rotary shaft, two pieces of thick, parallel plate, 49G pulley support plates are welded. The two 49G support plates have two pairs of matching holes. Through the coincident holes (not indicated in the figures), some perpendicular screws pass over the 49G plates, which allow the fixing of two pulleys, in a vertical plane. The two pulleys are connected with their circumferences in contact, allowing the insertion of the main cable 34, preventing it from jumping out of its grooves, when pulling it. Given the existence of the rotary axis 49F, the plates 49G, together with their pulleys, can make a 180 degree rotation in a horizontal plane, adapting to the direction of the tensile forces acting on the main cable 34.

The other pulley support 52, is also mobile, being formed by a pulley sliding support 52A, two side handles 52B, two plates 52C, a self-locking screw 52D and locking holes 52E. The pulley support 52 uses the internal vertical rectangular rail 15 as a slide guide. The pulley support 52 has a similar structure with the pulley support 49, except for the structure of the pulley plates 52C. The two 52C pulley plates are constructed of two pieces of thick sheet (15 mm thick). They are welded directly on the front face of the sliding support 52A. On the lateral faces of the two plates 52C, triangular elements are welded, which also connect with the front sliding support face 52A. The triangular elements increase the mechanical strength of the pulley support 52.

The pulley support 50 is formed by an upper plate 50A, an upper connector 50B, a lower plate 50C, a lower connector 50D and two pulley plates 50E. The plates, upper 50A and lower 50C, have holes at each end, which allow them to be fixed on the upper horizontal sleepers 59. The plates 50A and 50C, have cross-sectional profiles in the form of ^" U ^" (are the surfaces that do not come into contact with the upper horizontal sleepers 59). The peculiar design of the plates 50A and 50B increases the resistance of the two plates, so that they withstand higher loads (hundreds of kilos). Between the two plates 50A and 50C, the upper connector 50B, metallic, is prismatically welded. Under the 50C plate, the lower 50D connector is welded prismatically. In the basal part of the lower connector 50D, two pulley plates 50E, of thick sheet, and rounded margins are fixed. Each plate 50E has a hole in its center, coinciding with another, identical, located on the opposite plate 50E. Through the two holes of the plates 50E, a screw passes, which fixes a pulley in a vertical plane.

The pulley supports 51 and 53 are identical, and are each formed by a central prismatic support 51 A and 53A, two triangular connecting elements 10, two pulley plates 51 B and 53B. The two central prismatic supports 51A and 53A, have on each side face a triangular joint element 10. The two triangular joint elements 10, of the pulley support 51, are connected by the front side of the roof platform frame 55, with the two triangular connecting elements 10, of the pulley support 53. On the underside of each of the prismatic supports 51A and 53B, two pulley plates 51 B and 53B are fixed. Each plate 51 B and 53B, have a central hole coinciding with the plate 51 B, respectively 53B, opposite, belonging to the prismatic support 51 A or 53A. For each two holes, a screw passes, which fixes a pulley on each support 51 and 53. The plates 51 B and 53B, have on their lateral surfaces fragments of sheet metal, triangular in shape (not numbered in the figures), welded between the plates and the bottom of the prismatic brackets 51A or 53A. He Pulley support 54, is welded on support 56, presenting two plates 54A and triangular elements. The triangular elements are welded between the side faces of the two plates 54A and the support 56, increasing the resistance of the support 54.

The roof platform 55, of each tower, has the shape of a rectangular frame, connecting with several elements.

On the underside of the roof platform the triangular joining elements 10, form two anchoring groups: anterior and posterior.

Two of them serve to slide on the horizontal cylindrical rails 73, and another to slide on the horizontal rectangular rail 74. A cubic support 76, has on its upper face, at the lateral ends, four ears 77, forming pairs. Each pair of flaps 77, has two coincident holes, which connect with a rectangular articulated element 80, by means of a screw. The rectangular articulated elements 80 are made of rectangular steel bars (length 1000 mm, width 40 mm, material thickness 15 mm). Each rectangular articulated element 80, has at each of its ends a hole, which crosses it through two opposite faces. Through the hole in the lower face it is coupled with two lugs 77, belonging to a cubic support 76, and through the hole in the upper end it is coupled with a pair of accessory lugs 81, welded on the accessory plate 63. The support cubic 76 has a perforated element 78 on its front face, which associates a hole that crosses it by two opposite faces. The hole (not numbered in the figures), blocks the cubic support 76 at the level of the lower horizontal rail 73, by means of a fixing screw 79, with the head and nut in cross.

Every four rectangular articulated elements 80, connected with an accessory plate 63 and with two cubic supports 76, perform the necessary force arms, for lowering and raising the accessory plate 63, formed a ramp, which adjusts to different heights, for that the athlete has access, in a practical and easy way, to the devices installed on the upper horizontal sleepers 59.

The accessory plate 63 has two holes coinciding with the lumens of two cylinders 85. The cylinders 85 are welded on the underside of the accessory plate 63, by triangular shaped metal fragments (not numbered in the figures), which increase the strength of the joint made with the plate 63. Between each two cylinders 85, located on an accessory plate 63, a straight recess 83 is made, which in the central part is dilated forming a digital hole 84. The straight recess 83 , houses a retractable handle 82, in the form of an inverted ^" U ^" , built of solid steel bar, 20 mm in diameter. The retractable handle 82 passes through the holes and the matching cylinders 85, being locked in its lower part by nuts (not numbered in the figures). Thus, by inserting the fingers of one hand through the digital hole 84, and pulling in a vertical direction, the retractable handle 82 rises, allowing the accessory plate 63 to be moved in the same plane. When the traction ceases, the handle 82, goes down in the straight recess 83, avoiding user accidents, by slip or trip.

A transverse wheel support 71, which stores a wheel, connected to the support by a screw, is placed on the free side side of the fixed side support 72. The transverse wheel supports 71, together with their wheels, allow lateral displacement, necessary to remove and transport the central ramp out of the lower horizontal sleepers 9 (when performing a peculiar exercise or when the installation of an auxiliary machine is required).

Between the external (free) faces of the fixed lateral supports 72, and the lateral, external face of the sliding elements 64, a lateral wheel support 70 is placed. The lateral wheel support 70 is formed of a plate, welded perpendicularly on the fixed lateral support 72. The supports 70 together with their wheels, help the central ramp slide on the lower horizontal sleepers 9.

The wheels are placed in a peculiar way, the lateral ones rest directly on the ground the central ramp, and the transverse ones do not have contact with the same. The wheels can be made of hard rubber or nylon.

The sliding elements 64, have at their ends and on their lateral faces, holes coinciding with the equidistant holes 47, made on the lower horizontal sleepers 9. These holes together with the blocking screws 65, immobilize the central ramp at any level of the lower horizontal sleepers 9. The locking screws 65, have the head and nut in the form of a cross, for easy handling, eliminating the risk of unwanted displacement of the central ramp and accidents.

On the outer, free face, each of the fixed lateral supports 72, have two connecting pipes 66, of steel, welded, with the longitudinal axis oriented vertically, parallel to each other. The dimensions of a connecting tube 66 are: length 120 millimeters, external diameter 45 millimeters, internal diameter 30 mm). Each tube 66 has, on its longitudinal axis, a hole, which has a metric thread inside, necessary for connection with a fixing screw 67. The fixing screw 67 can have a cross-shaped head.

In connection tubes 66, a baluster 69 fits, with an inverted ^" U ^" design. The baluster 69 has at its lower ends two holes that are used for fixing with the tubes 66. On its way, the baluster 69 passes through two incoming holes 68, parallel, made on the ends of the accessory plate 63. It is then connected with tubes 66, by screws 67. Baluster 69 can be constructed of 30 mm diameter steel bar.

As the name implies, the baluster has two functions: 1) it ensures the sliding of the accessory ramp 63 in a vertical plane, offering stability; 2) allows a better balance of the athlete, avoiding accidents due to fall).

The oval plates 89 are identical pieces, with rounded contours, constructed of steel plate (dimensions: length 160 millimeters, width 120 millimeters, material thickness 15 millimeters), arranged in two vertical and parallel planes, with an increase in their thicknesses at the level of their internal faces, in their first half (30 mm thickness). The oval plates 89 are positioned between the two internal and lateral faces of the case 88, and the lateral faces of the mobile prismatic support 97. Each of the oval plates 89 has three holes. In the lower part of an oval plate 89, placed with its long axis in the vertical direction, a lower fixing hole 106 is made. lower fixing hole 106 connects the two oval plates 89, with the upper part of the sliding recess 98, through the middle of the lower fixing 99, forming a joint. The oval plates 89 have, in their central part, coincident middle holes 93, which, by means of a middle fastener 92, effectively block the plates in a vertical plane. The middle fastener 92 is a bar, without thread, which has a semi-circular head and nut. In the near of the upper ends of the oval plates 89, placed with their long axis in vertical direction, there are two upper fixing holes 91, coincident. A top fastener 90, represented by a thick screw, with a head and cross nut, passes through the two upper fixing holes 91. In upper fixator 90, it makes the connection between the two oval plates 89 and a central pulley 87.

When not in use, the center pulley system is housed inside the fixed box 88, and is covered by a protective shield 86.

In the upper part of the skeleton belonging to the central ramp, three metal plates (embossed iron sheet, 6 mm thick) are mounted, with steel screws (not indicated in the figures), which serve for a secure support of the feet. One of them, a central plate 62, is placed in the center of the central ramp, presenting a flat, rectangular opening (not numbered in the figures), which allows access to the elements contained in the fixed box 88. The central plate 62 it presents the protective shield 86, which is connected on the rectangular opening, with a handle (not numbered in the figures), of the same structure as the retractable handle 82 belonging to the accessory plates 63. The protective shield 86 prevents any sprains and other injuries, which could appear if the athlete would step on the hollow of the rectangular opening. The other two plates are the accessory plates 63, which connect by their accessory lugs 81, with the rectangular articulated elements 80.
