Definitions

  • the present invention relates to an elevator rail system and a rail.
  • An elevator rail system is typically used in an elevator to guide a traveling body, that is to say in particular a car or a counterweight.
  • the car is moved along a travel path between different floors or levels within a building.
  • the moving body has guide shoes that interact with the elevator rail system.
  • the moving body or its guide shoes cause forces on the elevator rail system.
  • the deformation of the elevator rail system due to these forces must be kept small so that the traveling body can always be guided precisely along the travel path. This is important because deviations from the travel path could result in the moving body touching stationary objects along the travel path, for example a shaft wall.
  • the rail is therefore anchored to a plurality of supports which are firmly anchored in the shaft wall or a corresponding solid base which extends along the travel path.
  • the rail is attached to the beams.
  • Known elevator rail systems essentially have at least one rail, one carrier and one fastening system.
  • Elevator rail systems are preferably simple and quick to install.
  • the rail is attached to beams with clamping elements.
  • a clamping element clamps the rail.
  • the clamping element is pressed onto the rail by one or more screws.
  • Such systems are complex to assemble, since many screws, washers and nuts must first be put together and then tightened with a suitable tightening torque.
  • the EP 0 459 033 shows an improved attachment of the rail to the beam by using a wedge to clamp the rail. In order to introduce the rail into the carrier, however, the rail must be rotated about its direction of extension.
  • One of the tasks of the rail is therefore to provide an elevator rail system that can be installed quickly and easily.
  • an elevator rail system for guiding vehicles in an elevator system fulfills the task.
  • the elevator rail system includes a rail, a bracket and a connector.
  • the rail has a holding profile which protrudes from a base area of the rail in the case of the holding profile or projects into the base area, the holding profile being wider at a part of the holding profile remote from the base area than at the base area.
  • the carrier can be anchored in such a way that it is suitable for holding the rail in place.
  • the carrier forms a carrier region which comprises a first part of the carrier region and a second part of the carrier region.
  • the rail forms a holding area which comprises a first part of the holding area and a second part of the holding area.
  • the first part of the carrier area rests against the first part of the holding area.
  • the second part of the carrier area and the second part of the holding area span an insertion area into which the connector is inserted.
  • the connector rests essentially on the second part of the carrier area and the second part of the holding area.
  • a rail for use in an elevator rail system fulfills the object.
  • the rail has a holding profile which protrudes from a base area of the rail in the case of the holding profile or projects into the base area, the holding profile being wider at a part of the holding profile remote from the base area than at the base area.
  • the holding profile essentially comprises three flat areas, with a first central area being aligned parallel to the base of the rail in the case of the holding profile, and two further lateral areas extending from the first central area to the base of the rail.
  • the rail according to the second aspect of the invention which is provided for use in an elevator rail system according to the first aspect of the invention, is preferably designed as a profile. That is to say, the rail has a cross section which remains essentially constant along a direction in which the rail extends. It is the direction of extension of the rail typically at least 10 times greater than a greatest length in cross section.
  • the rail is composed of rail elements of mostly the same length. The length of the rail elements is typically 5m.
  • the rail has a retaining profile.
  • the retaining profile protrudes from a base of the rail or into the base of the rail.
  • the base describes that surface of the rail that is directly adjacent to the retaining profile.
  • the base area is divided into two parts by the retaining profile, which are located on opposite sides of the retaining profile. Typically, the base area is flat on both sides adjacent to the retaining profile. Both sides are preferably in the same plane next to the retaining profile.
  • a retaining profile protruding into the base can be formed, for example, in the case of a solid rail by milling a groove.
  • a retaining profile protruding from the base can be formed, for example, in the case of a solid rail, by milling on both sides of the retaining profile, the retaining profile being left in place.
  • Such rails can preferably be created as hollow bodies. The rails are preferably produced by roll forming or extrusion.
  • the rail forms a holding area in the holding profile.
  • the holding area comprises an area of the surface of the rail in the case of the holding profile.
  • the holding area preferably comprises the surface of the holding profile and optionally an edge area of the base area adjoining the holding profile. However, only part of the surface of the retaining profile can also be included.
  • the holding area is divided into two non-overlapping parts, the first part of the holding area and the second part of the holding area.
  • the first part of the holding area and the second part of the holding area are defined in that they bear against certain surfaces of the carrier or of the connector. This is detailed below.
  • the carrier is used to hold the rail in place.
  • the carrier itself is anchored in a stationary manner.
  • it can be fastened in an elevator shaft with screws or other fastening means.
  • An elevator rail system usually has many carriers on.
  • the carriers are preferably aligned with one another in such a way that the carriers are aligned so that the rail attached to them runs straight.
  • the carriers are preferably evenly distributed in the elevator rail system. They are preferably 2.5 m apart. Alternatively, the distance between the floors in the building determines the distance between the beams.
  • One or more girders are attached per floor distance.
  • the carrier preferably has an adjustment facility for adapting the position of the rail mounted on the carrier.
  • This has the advantage that the carrier can be adapted to position errors of the shaft wall, that is to say to a position deviating vertically from a desired position of the shaft wall.
  • the adjustment option can be elongated holes.
  • Two square hollow profiles that can be telescoped into one another can be connected to one another in such a way that the inner square hollow profile has elongated holes and the outer square hollow profile has round holes.
  • a clamping device can be attached through an elongated hole and a round hole.
  • the clamping means are preferably screws with washers and nuts. Tightened firmly, the screws fix the carrier in a certain length.
  • an angle profile with first elongated holes can be anchored on the shaft wall.
  • the two profiles are connected with clamping devices. Such an arrangement can also compensate for angular errors in the shaft wall.
  • the carrier is preferably designed essentially as a profile.
  • the carrier can be designed from angle profiles.
  • the direction of extension of the profiles is preferably perpendicular from the shaft wall.
  • the direction of extension can, however, also be aligned parallel to the shaft wall.
  • the carrier has a carrier area.
  • the carrier area is designed to hold the rail with the holding area of the holding profile of the rail and with the assistance of the connector.
  • the carrier area is divided into two non-overlapping parts, the first part of the carrier area and the second part of the carrier area. The function of the first part and the second part of the carrier area will be explained further below.
  • the rail When assembling the elevator rail system, the rail can first be extended by a further rail element.
  • the lower end of the new rail element is connected to the already attached rail element.
  • the rail element can only be twisted with difficulty along the direction in which the rail extends.
  • the rail element is, however, relatively easy to bend elastically, so that the first part of the holding area can easily be brought into contact with the first part of the carrier area.
  • an insertion area is spanned by the second part of the holding area and the second part of the carrier area.
  • the second part of the holding area and the second part of the carrier area together form a jacket surface which surrounds the insertion area.
  • the second part of the holding area and the second part of the carrier area lie on this lateral surface.
  • the lateral surface can have a shape which is identical to the lateral surface of a prism. But it can also be identical to the lateral surface of a truncated cone.
  • the connector is inserted into this lead-in area.
  • the connector typically has a shape that is bordered by the lateral surface. In other words, this means that the rail and the carrier both touch the connector along the lateral surface.
  • One advantage is that it is very easy to assemble, since the connector can preferably simply be inserted by hand without any further aids.
  • the connector is also easy to remove again, since it is preferably not clamped in place by clamping forces in the insertion area.
  • the rail, the carrier and the connector form a form-fitting connection, so that the rail is held stationary in a direction perpendicular to a direction in which the rail extends.
  • the rail is secured against horizontal movements by the carrier, which is firmly anchored.
  • the rail is preferably held stationary in all directions perpendicular to an extension direction of the rail.
  • the rail is through the form-fitting
  • the composite is held in a fixed position so that it cannot rotate, in particular about an axis parallel to the direction of extent of the rail.
  • the rail in the elevator rail system can advantageously not rotate about an axis parallel to the direction of extension. Basically, all attachment points are on a straight line along this axis. These attachment points can act like a long hinge if they do not effectively prevent rotation.
  • it is advantageous that the first part of the carrier area and the first part of the holding area are relatively large, in particular in a direction perpendicular to the direction of extent and parallel to the base area.
  • the first part of the carrier area or the first part of the holding area should be longer in a direction perpendicular to the direction of extension of the rail than half of a longest length in the cross section of the rail.
  • the rail is advantageously secured against rotation about any arbitrarily oriented axis by the form-fitting connection.
  • the rail is formed from sheet metal.
  • the rail can comprise one or more metal sheets. If there are several sheets, these are, for example, welded, clinched, lashed or riveted to one another.
  • a rail can comprise several angle profiles made of sheet metal.
  • the rail is designed as a hollow profile.
  • the hollow profile can comprise a single sheet metal, which is preferably produced by roll profiling.
  • the rolled profile can be closed by a weld seam or by folding.
  • hollow profiles are often also produced by extrusion.
  • the hollow profile can also be created by joining several metal sheets, which are joined together in such a way that a cross section of the rail has several of the metal sheets. The advantage of the hollow profiles is that they achieve a very high level of strength with very little material and therefore also relatively little weight.
  • the holding profile comprises essentially three flat areas, a first central area being aligned parallel to the base of the rail in the case of the holding profile, and two further lateral areas extending from the first central area to the base of the rail.
  • the holding profile is essentially designed in a trapezoidal shape.
  • the longer, parallel side of the trapezoid thus forms the central area of the retaining profile.
  • the two legs of the trapezoid form the two lateral areas of the retaining profile.
  • the shorter parallel side of the trapezoid lies on the base of the rail.
  • the shorter parallel side in the area of the base can be viewed as virtual. This side of the trapezoid does not form a surface of the rail or the retaining profile.
  • the carrier area of the carrier is introduced into the holding profile through this shorter side of the trapezoid if the holding profile protrudes into the base area.
  • the shorter parallel side is not formed.
  • the three other sides of the trapezoid are shaped as sheet metal. It applies to all embodiments that the trapezoid can also be designed as an isosceles trapezoid.
  • the carrier is designed as a hollow profile, in particular as a square hollow profile.
  • a hollow profile has greater strength and lighter weight. This allows the carrier to be manufactured easily.
  • the carrier area is preferably formed at one end of a carrier profile using machining processes such as milling or grinding. Alternatively, however, prefabricated support areas, which are produced, for example, by die-casting processes, can also be attached to the support profile.
  • the carrier area is formed on a hollow profile using machining processes.
  • the resulting carrier areas have a smaller area than they would be with a full profile.
  • the design of the carrier area can also change and thus also change the holding area on the rail, although the rail remains materially unchanged.
  • the holding area is formed by the imprint of the bearing area resting against the holding profile.
  • the definition of the carrier area and the holding area results from the interaction between the rail and the carrier.
  • the connector has a head at a head end which has a cross section which is larger than the cross section of the insertion area.
  • the connector remains in the insertion area.
  • the connector could slip through the insertion area and fall out below.
  • the gravitation typically acts in the direction of the extension of the rail.
  • a head at the upper end of the connector prevents slipping through the insertion area by resting against the carrier.
  • the head of the connector is preferably designed or shaped so large that it can be easily grasped for removal from the insertion area.
  • the head has a handle for grasping the connector by hand. It is particularly advantageous that the head is designed so large that it protrudes beyond the carrier. This makes it very easy to grasp.
  • the connector at a second end, which is formed opposite the head end, has a cross section which is smaller than the cross section of the insertion area.
  • the second end opposite the head end has an at least slightly pointed shape which allows the connector to be easily inserted into the insertion area.
  • the connector can thus also be easily inserted if the rail is under tension during fastening.
  • the sharpened area preferably protrudes beyond the area of the jacket surface, so that the connector in the area of the jacket surface is essentially bordered by the jacket surface everywhere.
  • the second end can be configured so that the connector can be manually removed from the Insertion area can be pressed in that the second end has a surface to press on it.
  • the second end can also be configured so that the connector can be removed using a tool, for example a punch and a hammer.
  • the second end can have a hollow that is used to apply the punch or a similar tool.
  • the connector in particular at the second end, has a locking pawl which prevents the connector from accidentally sliding out of the insertion area.
  • the pawl comprises an elastically held locking element which engages in a recess on the carrier or engages behind that surface of the carrier which is opposite to the surface on which the head abuts.
  • the locking element advantageously has a lever, an extension or a pusher, by means of which the locking element is withdrawn from the recess. This makes it possible to release the pawl again if the rail is to be replaced.
  • the connector is made of plastic, it is advantageous to design the pawl in one piece as a pawl protruding from the connector.
  • the head of the connector can also be designed as a pawl.
  • the connector can then be configured essentially symmetrically so that it can be inserted into the insertion area with both ends first.
  • the carrier has a play in relation to the rail and the connector, so that the relative movement of the rail and the carrier in a direction parallel to the direction of extension of the rail is possible.
  • the rail is freely displaceable along its direction of extension, or at least displaceable along the carrier area with the application of little force. It is advantageous here that the rail is designed as a profile, and therefore the position of the holding area, which results from the contact of the carrier area and the connector, can move freely along the direction of extent of the rail.
  • the displaceability enables the girders to move along the rail as the shaft walls lose height as a result of building subsidence, and the Move the carrier down slightly while the rail essentially maintains its length.
  • Another advantage of this alternative embodiment is that it is very easy to assemble, since the connector can simply be inserted by hand without any further aids.
  • the connector is also easy to remove again since it is not held or clamped in place by clamping forces in the insertion area.
  • the carrier is clamped on the rail.
  • the carrier has no play between the carrier and the connector, but the connector is clamped between the carrier and the rail.
  • the insertion into the insertion area requires more force. Aids such as a hammer or press can be used.
  • the connector is preferably provided with a slot. Through the slot in the connector, which runs along the extension direction of the rail, the connector can narrow its cross-section under pressure, the pressure being exerted on the connector by the second part of the carrier area and the second part of the holding area. This allows the connector to adapt to the cross section of the insertion area.
  • the advantage of the second alternative embodiment is that due to the lack of play, the rail and the connector are held firmly. This effectively prevents rattling or squeaking between the rail, connector and carrier.
  • the carrier has a nose which engages behind the connector.
  • the advantage of the nose is that the form fit holds securely.
  • the play can turn out to be greater than actually intended due to manufacturing tolerances. From a certain game on, there is then the possibility that the form fit no longer holds securely.
  • the nose which engages behind the connector, ensures that the form fit securely holds the rail, even if there is a large amount of play.

  • the area to be inserted is a protruding area of the holding area or the carrier area.
  • the receiving area is a recessed area of the carrier area or the holding area.
