De acordo com essas ilustrações, o mecanismo eletromecânico para controle de pesos fracionários em estação de musculação, objeto da presente invenção, é aplicado em torres de pesos constituídas por duas colunas 1 verticais, com uma travessa 2 horizontal superior unindo-as e uma base 3 na parte inferior suportando as ditas colunas 1 , de modo a formar um espaço retangular entre as colunas 1 , travessa 2 e base 3 onde se alojam uma pluralidade de pesos unitários 4 empilhados, conforme pode ser visto nas figuras 1 e 2. Esses pesos unitários 4 possuem furos verticais que são atravessados por guias verticais 5 montadas entre a travessa 2 e a base 3, vide figura 1. According to these illustrations, the electromechanical mechanism for fractional weight control in a weight training station, The object of the present invention is applied to weight towers consisting of two vertical columns 1, with an upper horizontal cross member 2 joining them and a base 3 at the bottom supporting said columns 1, so as to form a rectangular space between the columns. 1, crossmember 2 and base 3 housing a plurality of stacked unit weights 4, as shown in figures 1 and 2. These unit weights 4 have vertical holes that are traversed by vertical guides 5 mounted between crossmember 2 and the base. 3, see figure 1.
Acima do peso unitário 4 superior existe uma placa de engate, com uma barra vertical 6 que atravessa todos os pesos unitários 4 por correspondentes furos centrais destes, estando essa placa presa à extremidade de um cabo de aço 7 que ergue os pesos unitários 4.  Above the upper unit weight 4 there is a hitch plate with a vertical bar 6 running through all unit weights 4 through corresponding central holes thereof, which plate is attached to the end of a wire rope 7 lifting unit weights 4.
O mecanismo eletromecânico promove o engate entre a barra vertical 6 e um dos pesos unitários 4, devidamente selecionado. O cabo de aço 7 passa a erguer, através da barra 6, o peso 4 selecionado mais todos os pesos acima dele.  The electromechanical mechanism promotes the engagement between the vertical bar 6 and one of the unit weights 4, properly selected. The wire rope 7 will lift through the bar 6 the selected weight 4 plus all weights above it.
A presente invenção consiste em agregar, aos pesos unitários 4, pesos fracionários equivalentes à metade, ou à metade mais um quarto de um peso unitário, com um seletor eletromecânico de engate seletivo.  The present invention consists in adding to unit weights 4 fractional weights equivalent to half, or half plus a quarter of a unit weight, with an electromechanical selector switch.
Nas figuras 3 e 4 o seletor eletromecânico para pesos fracionários consiste em usar a polia central 8 do topo da torre, que desvia para baixo, no centro dessa torre, o cabo de aço 7 proveniente da base 3, onde encontra-se uma polia 10 de desvio que leva o cabo, na horizontal, para a estação de musculação, como representado esquematicamente por seta, na figura 2.  In figures 3 and 4 the electromechanical selector for fractional weights consists of using the center pulley 8 from the top of the tower, which deflects down the center cable 7 from the base 3, where a pulley 10 is located. of deviation that leads the cable horizontally to the weight station, as shown schematically by arrow, in figure 2.
Assim, a polia 8 tem um eixo tubular 1 1 , montado em rolamentos 12 de mancais 13 fixados à travessa 2 da torre. O eixo tubular 11 se projeta para fora dos rolamentos 12 e recebe, em cada lado dos mancais 13, rolamentos 14 de duas polias 15, as quais tem canais para cabos de aço 16 de pequena bitola ou cinta. Thus, the pulley 8 has a tubular shaft 11, mounted on bearing bearings 12 fixed to the tower crossmember 2. The tubular shaft 11 projects out of the bearings 12 and receives on each side of the bearings 13 two-pulley bearings 14 which have cable channels 16 of Small gauge or strap.
Cada polia possui um engate 17 rotativo, frente a engate 18 homólogo, de um disco 19 montado deslizante longitudinalmente ao eixo 11. Em cada extremidade do mesmo eixo 11 , internamente, aloja-se uma vareta 20 cilíndrica, em cuja extremidade está montado um pino 21 , radial, que atravessa ortogonalmente furos oblongos 22 providos nas paredes opostas do eixo 11 , de modo a permitir o engate deste pino 21 no respectivo disco 19. A extremidade oposta da vareta 20 sai pelo furo do eixo e acopla-se a um cursor 23 de um atuador linear 24, através de uma junta rotativa 25, estando cada atuador 24 fixado a travessa 2 da torre. Como o descrito acima, o eixo 11 possui varetas 20 em cada extremidade e atuadores lineares 24, um para cada vareta 20.  Each pulley has a rotary coupling 17, in front of the homologous coupling 18, of a disc 19 slidably mounted longitudinally to the axis 11. At each end of the same axis 11, internally, a cylindrical rod 20 is housed, at which end a pin is mounted. 21 radially orthogonally traverses oblong holes 22 provided in opposite walls of shaft 11 to allow engagement of this pin 21 to respective disc 19. The opposite end of rod 20 exits through the shaft hole and engages a slider 23 of a linear actuator 24 via a rotary joint 25, each actuator 24 being secured to tower crossmember 2. As described above, shaft 11 has rods 20 at each end and linear actuators 24, one for each rod 20.
Como pode ser visto na figura 3, em uma das extremidades do eixo 11 ainda é provido axialmente um disco 26 com perfurações na periferia, disposto com a sua borda encaixada em dois sensores óticos 27.  As can be seen from Figure 3, at one end of the shaft 11 there is further axially provided a disc 26 with perforations at the periphery disposed with its edge fitted into two optical sensors 27.
Esses dois sensores óticos 27 localizam-se próximos entre si e numa distância não múltipla da distância entre furos do disco 26 de tal modo que a CPU do painel de comando reconheça o sentido do giro do disco 26, além de fazer a contagem da quantidade de furos em uma operação de subida, ou de descida dos pesos.  These two optical sensors 27 are located close to each other and at a non-multiple distance between the holes 26 of the disk 26 such that the control panel CPU recognizes the direction of rotation of the disk 26, and counts the amount of holes in an up or down operation.
Na figura 4 se pode observar que cada polia 15 tem o cabo de aço 16 (ou cinta), preso em um ponto rente ao fundo do canal, onde se encaixa seu terminal 28, e esse cabo de aço 16 prolonga-se para trás da torre onde se desvia para baixo, na vertical ao passar por uma polia de desvio 29.  In figure 4 it can be seen that each pulley 15 has the steel cable 16 (or belt), secured at a point near the bottom of the channel where its terminal 28 fits, and this steel cable 16 extends behind the tower where it deflects down vertically through a deflection pulley 29.
Na travessa 2 e na base 3 da torre fixam-se dois tubos 30 verticais, os quais recebem, de forma deslizante vertical, dois pesos cilíndricos, um peso 31 com massa de cinco quilogramas e o outro 32 com massa de dois e meio quilogramas, cada um em um tubo 30 e suspensos pelos cabos de aço 16, que se encontram em seus centros.  Two vertical pipes 30 are attached to the tower crosspiece 2 and base 3 of the tower, which are slidingly receiving two cylindrical weights, one weight 31 with a mass of five kilograms and the other 32 with a mass of two and a half kilograms. each in a tube 30 and suspended by the steel cables 16, which are at their centers.
Os tubos 30 são fechados nas extremidades inferiores, e podem conter ao fundo coxins 33 de borracha para amortecer choque de algum dos pesos 31 ou 32 que cair em queda livre por ruptura do respectivo cabo 16. Fechados embaixo, os tubos também ajudam a amortecer a queda livre por compressão de ar parcial com peso atuando como pistão. Os pesos 31 e 32 ficam pendurados pelos respectivos cabos de aço 16, sem tocar o fundo dos tubos 30, mantendo tracionados esses cabos, os quais manterão suas polias 15 sempre na mesma posição quando não acionadas. The tubes 30 are closed at the lower ends, and may contain bottom rubber cushions 33 to cushion shock of any of the weights 31 or 32 that fall free from rupturing the respective cable 16. Closed down, the tubes also help cushion the free fall by weighted partial air compression as a piston. Weights 31 and 32 hang from their respective steel cables 16, without touching the bottom of the tubes 30, keeping these cables in tension, which will always keep their pulleys in the same position when not driven.
Para acionar-se o levantamento de um ou de dois pesos fracionários 31 e 32, em conjunto com os pesos unitários 4 selecionados da torre, o painel eletrônico de comando aciona um atuador linear 24 ou ambos. O atuador empurra a vareta 20 axialmente para dentro do eixo 11 , que, por meio de seu pino 21 leva o disco 19 no sentido da polia 15, unindo os engates 17 e 18, de tal forma que a polia 15 passa a girar conduzida pelo eixo 11. Nessa condição a polia 15 enrola o cabo 16, suspendendo o peso 31 ou 32, ou ambos. Quando o peso unitário 4 da torre é de 10 quilogramas, usam-se pesos fracionários de cinco quilogramas e dois e meio quilogramas, para que seletivos acionamentos dos dois atuadores lineares 24 possam preencher o intervalo entre pesos de 10 quilogramas em quatro intervalos iguais.  To trigger the lifting of one or two fractional weights 31 and 32, together with the selected unit weights 4 of the tower, the electronic control panel drives a linear actuator 24 or both. The actuator pushes the rod 20 axially into the shaft 11, which, by means of its pin 21, drives the disc 19 towards the pulley 15, joining the couplings 17 and 18, such that the pulley 15 starts to rotate driven by the shaft 11. In this condition the pulley 15 winds the cable 16, suspending the weight 31 or 32, or both. When the tower unit weight 4 is 10 kilograms, fractional weights of five kilograms and two and a half kilograms are used so that selective drives of the two linear actuators 24 can fill the 10 kilogram weight interval at four equal intervals.
O disco 26 e os sensores óticos 27 fazem a leitura do movimento angular da polia 8, que está relacionado com o movimento linear do cabo de aço 7 e portanto, com o deslocamento dos pesos 4 unitários, sendo esses dados transmitidos ao painel eletrônico da estação de musculação, que os interpreta e integra com os dados de peso informados pelo sensor do sistema de seleção e exibe na tela do painel a energia gasta no exercício.  The disk 26 and the optical sensors 27 read the angular movement of the pulley 8, which is related to the linear movement of the wire rope 7 and therefore to the displacement of the unit weights 4, which data is transmitted to the station's electronic panel. weight training, which interprets and integrates it with the weight data reported by the selection system sensor and displays on the panel screen the energy expended on the exercise.
