Definitions

  • the present invention relates to a profiled shaft structure as defined in the preamble of claim 1.
  • the elevator shaft is provided with separate guide rails for the car and the counterweight.
  • the elevator and its counterweight travel in the elevator shaft along the guide rails guiding them, on which they are supported by means of sliding guide shoes.
  • the arrangement is called "rucksack suspension".
  • elevator guide rails and the various adjustable brackets used to hold them are separate parts, requiring some space in the lateral direction of the shaft.
  • US 6012554 presents a profiled guide rail element for use in an elevator shaft, combining the parts serving as car and counterweight guide rails into the same structure.
  • the guide rails consist of separate parts which are connected to each other by means of certain fastening elements.
  • the profiled element comprises a U-shaped part to which are attached L-shaped parts which together form guide rails for both the counterweight and the car.
  • the EP 442230 A1 discloses a guide rail supporting structure comprising U-type profiles wherein different guide rail elements may be fastened for the building of the car and counter weight guide rail.
  • the US 5,725,074 discloses a guiding and supporting structure for an elevator which structure is constructed as a closed column which is mountable to shaft walls, which column comprises on its outside guide surfaces for rollers of the elevator car and in its interior profiled guide rail structure for a counter weight running within the column.
  • the WO 98/18709 discloses an elevator guide rail consisting of several U-shaped profiles which can be mounted together to form guide rails for the elevator car. The profiles are mounted end to end to build the guide rails along the length of the elevator shaft. The profiles are mounted to support structures mounted in connection with the elevator shaft.
  • the object of the invention is to disclose a shaft structure that can be accommodated in a space as small as possible and which can be constructed economically and quickly.
  • a shaft structure that can be accommodated in a space as small as possible and which can be constructed economically and quickly.
  • the object of the invention can be achieved by integrating the guide rails for the counterweight and the car into the same structure, a so-called profiled shaft structure.
  • the profiled shaft structure to be mounted in an elevator shaft can be fixed to the building at points around the shaft space, and the structure consists of one or more successive lengths of profiled shaft structure connected endwise together.
  • the profiled structure functions in the shaft as a structure supporting the elevator, and the profiled element is provided with a protrusion extending in the direction of the shaft and functioning as a counterweight guide rail, which profiled element can be provided with a car guide rail.
  • the profiled elements have been formed from an elongated metal plate by bending the plate in relation to its longitudinal axis. It is also possible to produce the profiled element of the invention by roll forming or by extruding e.g. from aluminum.
  • the profiled shaft element is preferably manufactured from a single piece of durable material, such as steel, machined to shape. Using the profiled element makes it possible to save shaft space and minimize the costs. The material, installation and maintenance costs are reduced as a single piece is used instead of many pieces. According to the invention, the profiled structure is open toward the direction where the counterweight is located.
  • profiled structures When two profiled structures are mounted opposite to each other on either side of the shaft, they will together form a load-bearing structure of the elevator, being supported on the floor at the shaft bottom and attached by other parts to fixed building structures.
  • the profiled structures bear all the forces applied to them from the elevator, and both the machine and the counterweight are placed in the space between the profiled structures.
  • the profiled shaft element comprises a back part and a front part and an end part, both being substantially perpendicular to the back part, with an edge part extending inward from the end part, adding to the rigidity of the structure.
  • the edge of the front part of the profiled element is further bent so as to form a projection which functions as a car guide rail.
  • a connecting piece can be provided between the back part and the projection to render the structure more rigid, or
  • the profiled element comprises a mounting bracket preferably extending inward from the front part of the profiled element in a direction parallel to the back part, to which the car guide rail is fastened, allowing a car guide rail to be attached to the outer surface of the mounting bracket.
  • the profiled shaft element comprises a back part and, projecting in the same direction from the back part, a front part and an end part, both being substantially perpendicular to the back part, with an edge part extending inward from the end part, adding to the rigidity of the structure.
  • the projection functioning as a counterweight guide rail has been formed by working a portion of the back part of the profiled element into a triangular shape in cross-section, allowing an advantageous distribution of the forces applied to the guide rail. Sliding guides attached to the counterweight can be easily mounted on the projection so that they can slide along the guide rail.
  • the projection forming the counterweight guide rail can be formed by working a portion of the back part of the profiled element into a substantially rectangular shape in cross-section.
  • the supporting structure for an elevator comprises two profiled shaft structures mounted at a distance from each other.
  • the profiled structures bear all the forces applied to them from the elevator.
  • two profiled shaft structures are mounted opposite to each other on either side of the shaft, they form together a load-bearing structure supporting the elevator, resting on the floor at the shaft bottom and fastened by other parts to fixed structures of the building.
  • the profiled structures can be connected to each other.
  • the elevator machine and the counterweight can be placed substantially between the profiled structures.
  • the distance between the counterweight guide rails provided in the profiled shaft elements is larger than the distance between the car guide rails.
  • the width of the counterweight can be increased and therefore its height reduced, which means that less shaft space is needed in the vertical direction.
  • the structure comprises a mounting bracket preferably extending inward from the front part of the profiled element in a direction parallel to the back part.
  • a guide rail for the elevator car can be mounted on the mounting bracket. In this way, preferably the same piece can be used both as a counterweight guide rail and as a mounting surface for the car guide rail.
  • the profiled shaft element can be provided with a tightening element placed between the mounting bracket and the back part to strengthen the structure. Tightening elements are placed in the profiled shaft structure at certain distances between them.
  • the total width defined by the profiled elements is 1000 mm, on which it is possible to suspend e.g. cars having a width of 800, 900 or 1000 mm.
  • Cars of different widths are mounted on the profiled elements by moving the cladding walls surrounding the profiled elements farther apart.
  • the same profiled structure of the invention can be used in the implementation of many elevator solutions.
  • the cladding walls are attached to the profiled elements using certain fastening elements, such as bolts.
  • the profiled structure is fastened directly to the fixed structures of the building.
  • a structure having a height corresponding to the shaft height and consisting of profiled elements according to the invention can be easily and quickly erected and it can be assembled as a prefabricated member at factory or installed from components on site. In addition, it allows easier assembly of the elevator. By using a profiled element as provided by the invention, a compact shaft structure assembly is achieved while saving shaft space.
  • Fig. 1 presents a top view of the profiled shaft element 1 of the invention, which is a cross-sectional view of the structure in Fig. 3 , taken along the dotted line A-A.
  • the profiled element comprises a back part 9 extending in the longitudinal direction of the shaft, with an end part 2 projecting in a substantially perpendicular direction from the back part and an edge part 3 extending inward from the end part at a certain angle to stiffen the structure.
  • the structure comprises a front part 4 projecting from the back part, with a mounting bracket 5 extending in a substantially perpendicular direction from the front part to allow a car guide rail 8 to be attached to its outer surface.
  • a protruding part 6 which functions as a counterweight guide rail, guiding the guide shoes 7 of the counterweight.
  • the profiled shaft element 1 is mounted longitudinally in the elevator shaft, and individual profiled elements can be connected to each other so as to form a profiled shaft structure extending through the entire height of the elevator shaft.
  • the car guide rail 8 is fastened to the mounting bracket 5. Depicted in the figure is also a fastening element 11, which are used to connect the separate profiled shaft element lengths to each other. Tightening elements 12 are fixed to the profiled structure at given distances to maintain the rigidity of the structure.
  • Fig. 2 presents another embodiment of the invention.
  • a profiled element consisting of a single piece has been bent so as to form both a counterweight guide rail 6 and a car guide rail 15.
  • the structure is braced by a connecting piece 14 fixed to the profiled element by means of fastening elements 13, such as e.g. bolts.
  • the profiled element also comprises a back part 9 from which an end part 2 projects in a direction perpendicular to the back part, with an edge part 3 extending inward at a given angle from the end part. Further, projecting from the back part is a front part 4 with a projection 15 protruding from it, forming a car guide rail.
  • Fig. 3 illustrates the manner in which the profiled elements 1 are fastened to each other in the longitudinal direction of the elevator shaft by means of fastening elements 11 placed at the juncture between profiled elements.
  • the figure shows a view at the upper end of the shaft.
  • the figure also shows the tightening elements 12 used to stiffen the structure.
  • mounting elements 10 Disposed at the upper end of the shaft are mounting elements 10 serving to hold the machine of the elevator between the profiled structures.
  • Fig. 4 shows how profiled shaft structures support an elevator.
  • the landing doors comprised in the elevator system are mounted in the surrounding structures in a conventional manner and are not shown in the figure. Neither does the figure show the cladding elements surrounding the elevator, nor the car, which is placed in a car frame 18 supporting it.
  • the figure shows how the drive motor 16 is mounted on a transverse supporter 19 connected to the profiled elements 1. All rope pulleys guiding the ropes, the traction sheave 24 of the drive motor, the counterweight rope pulley 22 and the car rope pulley 23 are located on the same side in relation to the elevator car.
