Definitions

  • the invention concerns a platform of an elevator car having several integrated functions.
  • Said platform comprises a rectangular frame constituted by steel beams welded together.
  • a floor made of a steel plate, with interposition of several antivibratory and acoustic insulating blocks, made of rubber.
  • a load scale which is generally constituted by a housing equipped with several switches which define load thresholds on the basis of deformations of the floor and of the blocks.
  • the platform also includes at its entrance edge a door-sill profile for guiding the lower edge of the doors of the elevator car.
  • Such a platform which uses massive steel elements is heavy and expensive.
  • the mounting of the platform is long and complicated since the operator needs to secure on the site the insulating blocks and the load scale to the frame and then to fix the floor and the door-sill profile.
  • the antivibratory and acoustic insulation functions are ineffective due to the fact that the blocks are secured only at discrete points of the platform.
  • the load scale is sensitive only to loads located substantially above it.
  • a powerful motor is required to actuate it.
  • the invention concerns an elevator car platform which comprises:
  • the present invention provides a platform for an elevator car which integrates all the above-mentioned functions and which is lighter and less expensive than those of current platforms.
  • the base may be made of a composite material having a honeycombed structure whose alveoles are filled with an acoustic insulating foam.
  • the base may also be made of any other laminated material, such as wood plates glued together.
  • the lower and upper skins of the base and of the floor may be constituted by steel sheets. Tapped inserts may be embedded in the edges of the base for screwing vertical girders or tie rods which normally connect the platform to an upper crossbeam of the car.
  • the sensitive layer may be constituted by discrete sensors or piezoelectric elements disposed at selected points of the base.
  • the sensitive layer comprises an optical fiber contorted in such a way as to form a flat network.
  • each of the components of the platform fulfils a specific function on the entire surface of the platform.
  • the integration of all the functions in the platform makes it possible to use a minimum of components and to simplify its construction.
  • the weight of the platform is thus reduced, so as the time involved for constructing and for mounting the platform and consequently the cost of the platform are reduced.
  • the integration of the antivibratory function over the entire surface of the honeycombed base results in a reduction of the level Of vibrations and noise of the car compared with known types of platforms where the antivibratory insulation is ensured by rubber blocks localized only at local points of the surface of the platform.
  • the load scale function is significantly improved since the sensitive layer extends over the entire surface of the platform.
  • the comfort of the passengers is thus improved at the starting of the car, owing to the suppression of jerks resulting from a better control of the motor. A better precision of stopping is obtained.
  • the elevator car platform 10 comprises a base 12 constituted by a plate of constant thickness and having a honeycombed structure.
  • Said base may be made of aluminium or a composite material and its alveoles are filled with an acoustic foam which ensures the insulation of the platform against noise.
  • the base may also be made of wooden plates glued together.
  • Metallic inserts are embedded in the region of the peripheral edge of the base so as to allow the screwing of screws or bolts.
  • a lower skin 14 and an upper skin 16 both constituted by steel plates are glued or screwed to the horizontal faces of the base respectively.
  • Two parallel edges of the lower skin are folded at a right angle so as to form vertical borders 18,20 which cover the sections of the base.
  • On these borders are secured the lower ends of four vertical tie rods 24 by means of bolts.
  • the upper ends of the tie rods are connected to upper crossbeams (not shown).
  • a sensitive layer 26 acting as a load scale is secured to the upper skin 16.
  • Said sensitive layer may be constituted by a single optical fiber contorted so as to form a flat network through which a luminous beam circulates. It is known that the amount of light transmitted by this fiber depends on the mechanical pressure exerted on it.
  • the base 12 and its two skins 14,16 slightly project with respect to the sensitive layer 26 on the region of the two parallel walls of the car ( Figure 2).
  • the sensitive layer 26 is covered with an elastic cushion 28 having the same surface area as the base and intended to carry out the antivibratory insulation of the car.
  • the two faces of the floor are coated with skins 32,34 made of steel.
  • Tapped inserts 36 are embedded on the lateral edges of the floor for securing the vertical walls 38 of the car.
  • the floor 30 and its skins 32,34 extend over the entire surface of the cushion 28, except an entrance edge zone having a constant width and height.
  • a door-sill profile 40 having the same height and width as said edge zone is secured in the latter, whereby its upper face is flush with the upper face of the skin 34.
  • the door-sill profile 40 has on its upper face several longitudinal grooves 42 (two in the case of Figure 3) for guiding the lower edges of the doors.
  • the platform thus integrates all the conventional functions of the load scale, acoustic and antivibratory insulation and individual support floor.
  • the platform is relatively light since it comprises few metallic elements. Its construction is very simple and does not require any welding of its elements.
  • the platform is delivered on the mounting site fully assembled and ready to receive the walls 38 and the vertical tie rods 24.
