Abstract:
A device for the guidance, in rectilinear translation in a given direction, of an object that is mobile in relation to a first object, the guidance device comprising:a first parallelogram, called an intermediate parallelogram, having firstly a pair of bands that are flexible in the direction of translation, known as intermediate bands, substantially equal and parallel to each other, each of said intermediate bands being embedded at a first end in a fixed base, joinable to a fixed object and, secondly, an intermediate rigid element, parallel to the direction of translation, fixed at each of its ends to a second end of the intermediate bands;a second parallelogram, called a guidance parallelogram, opposite the first parallelogram and having, firstly, a pair of bands that are flexible in the direction of translation, known as guidance bands, substantially equal and parallel to each other and to the intermediate bands, each of said guidance bands being fixed, at a first end, to said intermediate rigid element and, secondly, a rigid guidance element, parallel to the direction of translation, joinable to a mobile object and fixed at each of its ends to a second end of the guidance bands, wherein said guidance device includes a motion reduction lever that is fixed-at a first end to said fixed base by means of a first flexible reduction band;at a second end to the rigid guidance element by means of a second flexible reduction band; andin its middle to the intermediate rigid element by means of a third flexible reduction band.
