  Technical cabin for air transport by cables Technical field of the invention The invention relates to a cabin for air transport by cables, comprising: o - a metal frame associated with a lifting beam through a device of damping, said frame being composed of vertical uprights in the form of profiles secured by means of assembly to lower crosspieces and to upper crosspieces parallel two by two, - and an envelope fixed to the frame and comprising walls

  transparent, and a double door.

  State of the art o Known cabins generally include an H-shaped spreader located above the tone, and connected to the frame by four vertical tie rods with the interposition of shock absorbers. The junction between uprights and crosspieces is carried out by means of gussets, which wind independent of the tie rods. The lifting beam is visible from the outside, and the tie rods work in traction in the intermediate part

  z5 between the uprights and the lifting beam.

  Object of the invention The object of the invention is to provide a cabin for air transport by so cables, making it possible to improve the upper structure of the mechanical connection to the suspension beam, to simplify the junction between the uprights and the cross members of the metal framework, and to facilitate periodic regulatory inspections of the cabin by making the fasteners visible from the outside. The device according to the invention is characterized in that: - the upper end of each upright is extended by an extension projecting from the horizontal plane defined by the upper crosspieces, - and a fixing device is assembled at the extension of each amount

  by being fitted with a shock absorber for connection to the spreader.

  Such an assembly allows the pieces of the fixing device not to work or in traction, by ensuring a uniform distribution of the forces between the uprights and

the lifter.

  According to a preferential mode of reaiisation, the fixing device comprises a pad of plates enclosing said extension by forming a rigid connection with the associated upright. According to a characteristic of the invention, the damper of each fixing device is formed by a stud made of elastic compressible material interposed between

  the upper end of the plates and an arm of the lifter.

  The extension to which the fixing device relates, may have a section

  identical or different from that of the associated amount.

  Description of a preferential embodiment

  In FIGS. 1 to 4, a cabin 10 used for air transport by cable, comprises a metal frame 11 connected to a suspense (not shown) by the intermediary of a link pioneer 12, which is mounted on a device

amortization.

  The frame 11 jigure 2A) is composed of four vertical uprights 13 connected to four lower crossbars 14 and to four upper crossbars 15 parallel two by two. The four lower cross members 14 constitute a rectangular section delimiting the horizontal base on which the floor 16 of the cabin 10 is supported. The four upper cross members 15 also form a horizontal rectangular section intended for fixing the tone 17 arranged under the lifter 12. The four uprights are made by aluminum profiles of identical structures, each upright having a convex intermediate ao part extended on both sides by rectilinear sections

connected to crosspieces 14, 15.

  The frame 11 serves as a support for an envelope 18 comprising transparent walls fixed to the uprights 13. A door 19 with two movable leaves is arranged in one of the lateral faces of the envelope 18 for access to the interior of the cabin 10. A mechanism (not shown) located at the upper part of the cabin 10, is coupled to pivoting arms for moving the leaves between a closed position (igure 1) and an open position (Figure 2). The upper end of each upright 13 is extended by an extension forming part of the aluminum profile, and being projecting from the horizontal plane defined by the upper cross members 15. The cross section of

  o the extension 20 is substantially identical to that of the associated amount 13.

  With reference to FIGS. 5 to 9, a fixing device 21 is secured to the extension 20 of the uprights 13 to ensure the junction with the lifter 12. The fixing device 21 comprises a pad of plates 22 made of steel, enclosing the two opposite faces parallel to each extension 20, forming a rigid mechanical connection. The assembly is carried out by means of rivets 23, or

any other fixing device.

  The fastening device 21 of each upright 13 is fitted with a shock absorber 25 connected to an arm 26 of the lifter 12. The arms 26 of the lifter 12 are arranged horizontally in an H shape, being fixed to the shock absorbers by stirrups 27 in U. The dampers 25 are advantageously formed by studs made of elastic compressible plastic. It is clear that everything

  other damping system can be used.

  Each damper 25 is mounted on the fixing device 21 by

  The intermediary of two bolts 28 framing a vertical axis 29 passing through the stud.

  The arms 26 of the lifter 12 ensure a uniform distribution of the forces between the frame 11 and the suspense. The forces flow directly from the uprights 1 3 to the cross beam 12 thanks to the arrangement of the four fixing devices 21 associated with the shock absorbers 25 at each extension 20 of the uprights 13. Such an assembly makes it possible to remove any additional tie rod for the assembly

shock absorbers on the spreader 12.

  The presence of the fixing devices 21 at the end of the uprights 13 also makes it possible to facilitate the mechanical connection between the uprights 13 and the crosspieces 15. The assembly and safety members, in particular the rivets 23 or bolts, are perfectly visible from the outside of cabin 10, which

  facilitates periodic regulatory inspections.

  In FIGS. 10 to 12, the cross section of the extension 20 of each fastening device 21 is less than that of the associated upright 13. The base of each plate 22 is provided in addition to a bracket 24 intended to ensure the junction of a cross member 15 with the corresponding amount 13. The fixing is carried out by rivets 23A on a mepiat of the upright 13. The fixing device 21 thus serves as a common junction for the upper crosspieces 15 and the

spreader 1 2.
