Definitions

  • the present invention relates to a helical staircase.
  • a spiral staircase of the type comprising a central shaft, a set of steps each having a tread having the shape of a disk sector, at least one mounting plate adapted to connect to the drum a corresponding step.
  • the patent FR 2,712,010 describes a helical staircase of the type described above.
  • This document describes a staircase comprising a device for fixing the steps to the central shaft.
  • the device for fixing the steps comprises a fastener having a curvature adapted to that of the central shaft which is disposed between the plate and the central shaft.
  • this document does not describe a staircase with adjustable steps, that is to say composed of different modules assembled to each other, which may have modifiable dimensions and a different size depending on the location where is arranged the staircase.
  • each step comprises profiles held on the corresponding plate and adapted to support the tread of said step, the plate having two projecting portions, which extend in a plane substantially perpendicular to the shank, on which the profiles are held, the two projecting portions defining between them an angle ⁇ substantially corresponding to the angle of the disk sector formed by the tread.
  • the spiral staircase according to the invention has elements that can be used regardless of the final dimensions of the staircase. These elements have easily adaptable shapes. In addition these elements can easily integrate security means, independently of each other.
  • the spiral staircase according to the invention consists of a set of steps and plates, a step 10 and a plate 12 are shown on the figure 1 appended disposed in a helical direction centered on the axis of the barrel.
  • Each step 10 comprises a tread 14, which extends in a substantially horizontal plane and on which the user bears.
  • the tread 14 has the shape substantially of a disc sector, the arc 16 of which is located on the side opposite to the barrel 13.
  • the tread 14, has on its upper face 18 anti-slip means 20 ensuring a sufficient friction to prevent the user from slipping the step 10.
  • These means 20 are known and may for example have the shape of a perforated or stamped anti-slip surface.
  • the tread 14 is made of a material selected from the group consisting of metal alloys, polymeric materials, composite materials, wood, glass.
  • Each tread 14 rests on two tubular sections 22, 24 hollow made of extruded metal.
  • each tread is fixed on two sections 22a, 22b by rivets 26.
  • the profiles 22a, 22b extend longitudinally between a first end 28a, 28b located on the side of the shaft 13 and a second end 30a, 30b.
  • the first end 28a, 28b of each profile 22a, 22b is held on the plate 12, by screwing.
  • the second ends 30a, 30b of the profiles are connected to each other by means of a closing strip 32 in an arc of a circle, substantially identical to the arc formed by the disk sector sector.
  • the closure band 32 is adapted to support the tread 14.
  • the closing band 32 is fixed to the profiles by a self-tapping threaded socket 34 for quick and easy attachment.
  • Each step 10 constituted at least by a tread 14, two sections 22a, 22b and a closure strip 32 has, after assembly, a symmetry with respect to a substantially vertical median plane.
  • the steps 10 can then be used either for a staircase with left propeller or propeller on the right.
  • Each step 10 is attached to the drum 13 by means of the plate 12.
  • the plate 12 is fixed on one side to the drum 13 by screwing, and is connected on the opposite side to the profiles 22a, 22b of the step 10.
  • each plate 12 has two longitudinal portions 36a, 36b protruding in the opposite direction of the barrel.
  • the longitudinal portions 36a, 36b extend in a substantially horizontal plane, perpendicular to the barrel 13.
  • the two longitudinal portions 36a, 36b are spaced apart angularly by an angle ⁇ and present a substantially tubular hollow shape, opening on the one hand on the side of the barrel 13 and opening on the other side of the profiles 22a, 22b.
  • Each plate 12 is made in one piece by molding. It is thus possible to achieve the desired shape of the plate by modifying the mold. It is in particular possible to modify the angle ⁇ defined between the two longitudinal portions 36a, 36b.
  • the two sections 22a, 22b of a step 10 are respectively nested on the two longitudinal portions 36a, 36b, so that the longitudinal portions 36a, 36b respectively open inside the sections 22a, 22b.
  • the tread 14 is then arranged and fixed on the profiles 22a, 22b which have an angle ⁇ between them. It is then necessary for the angle of the disk sector defined by the tread to be substantially equal to the angle ⁇ .
  • the angular spacing ⁇ between the two longitudinal portions 36a, 36b thus determines the angle of the disk sector delimited by the tread 14.
  • the profile 22a located at the front of the step forms a stair nosing and is adapted to receive signaling means improving the visibility of the march and therefore improving the safety of users.
  • the hollow shape of the profiles 22a, 22b and longitudinal portions makes it possible to insert wiring elements for supplying light systems integrated in the profiles.
  • the profiles 22a, 22b have at least one longitudinal groove 28 adapted to receive light means 40 such as an LED lighting system or a strip of contrasting color material or photoluminescent.
  • the profile may have holes for connecting the LED lighting system with the wiring.
  • the profiles 22a, 22b can receive, on the face facing upwards, an anti-slip element 42 formed of longitudinal ridges and arranged over the entire length of the profile 22a, 22b.
  • the figure 2 represents a sectional view of a profile 22a according to the invention.
  • Each section has two receiving grooves 44, 46 adapted to receive the tread 14 and having a different depth.
  • the profile 22a will be oriented, that is to say will be arranged at the front or rear of the step, depending on the thickness of the tread desired by the manufacturer.
  • each profile 22a, 22b comprises two grooves 38 adapted to receive light means 40.
  • the grooves 38 are disposed substantially symmetrically with respect to a horizontal median plane of the profile.
  • the latter comprises an upwardly directed groove 38 in which a luminous means 40 is inserted.
  • the present invention provides a modular helical staircase, that is to say composed of different modules assembled to each other, the dimensions of each module can be easily modified, so as to obtain adaptable stairs.
  • each module has elements improving the security of the users.
  • the staircase according to the invention thus makes it possible to integrate all the functions recommended by the "Fire safety regulations relating to establishments open to the public".
