Definitions
- Elevators for transporting people and goods contain elevator cars that can be moved up and down in an elevator shaft.
- the elevator cars can be moved via suspension means, for example in the form of suspension cables or straps, by means of a drive unit in the vertical elevator shaft.
- the elevator usually includes at least one counterweight that is moved in opposite directions in the elevator shaft.
- guide rails are used that are attached to the elevator shaft. T-shaped metal profiles have been known and used for a long time.
- the guide rails consist of individual guide rail segments, which are fixed in the elevator shaft using mounting brackets.
- EP 1 321 416 discloses a guide rail arrangement for elevators with such a mounting bracket.
- This mounting bracket has a U-shape, with the crossbar of the mounting bracket being fixed to the door-side shaft wall.
- the mounting bracket has two legs that extend from the ends of the crossbar into the elevator shaft. Guide rails or guide rail segments are attached to these legs. Both the crossbar and the legs are therefore arranged within the cross-sectional area of the elevator shaft, whereby the usable shaft space, i.e. the free cross-sectional area of the elevator shaft suitable for the elevator car to be moved, is reduced.
- the cross-sectional area of the elevator shaft means the area seen in the plan view or in the vertical direction for the cavity specified by the elevator shaft.
- the shaft space which is often rectangular in plan view, i.e. the cross-sectional area of the elevator shaft, is limited by the shaft walls.
- the main components i.e. the cross member and the two side members of the mounting bracket, have the following purpose:
- the cross member comprising the at least one floor fixing section is used to fasten the mounting bracket to the elevator shaft.
- the guide rails are fixed to the side supports.
- a washer plate designed, for example, according to a washer causes a pre-fixation or final fixation of the mounting bracket on the floor due to the degree of its pressure by means of the screw on the mounting bracket.
- Such an adjustability enables the mounting bracket to be pre-fixed on the floor and a subsequent alignment and final fixing of the mounting bracket in the elevator shaft using straightening elements that can be arranged in the elevator shaft.
- the floor fixing section has a plate-like support structure, preferably formed by a metal sheet, which support structure extends over the entire length of the cross member.
- Coupling elements can protrude into the cross-sectional area of the elevator shaft.
- a further aspect of the invention then relates to a mounting bracket for an elevator system for mounting on a shaft door opening and in particular for the elevator system described above.
- the mounting bracket preferably forms a bracket structure which is U-shaped in a top view and has a cross member extending in a first direction and two side members projecting away from the cross member and each extending in a second direction, which runs transversely and preferably at right angles to the first direction .
- the cross members and the two side members are preferably arranged relative to one another in such a way that they define the “U” mentioned.
- the elevator of Figure 1 can be designed as a traction elevator system 1 and, in addition to the elevator car 5, have at least one counterweight (not shown) that can be moved in the opposite direction to the elevator car 5.
- special guide rails 3 can be used, which serve as linear guides both for the elevator car 5 and for two counterweights.
- the traction elevator system 1 can have two drives (not shown).
- the two drives e.g. traction sheave drives
- drive the respective suspension means and thus move the elevator car 5 and the two counterweights in opposite directions.
- Each drive is assigned to one of the counterweights.
- two opposing guide rails 3 are provided on both sides of the elevator car 5.
- the elevator system can have special guide rails 3, which serve as linear guides for both the elevator car 5 and the respective counterweights.
- These guide rails 3 can be manufactured as one-piece rolled profiles.
- the guide rails 3 can be hollow profiles, for example manufactured as one-piece rolled profiles. Further details on the design of such special guide rails and on the guidance of the cabin and the counterweights with common guide rails can be found in WO 2020/127787 Al.
- the mounting bracket 30 enables the guide rails 3 to be advantageously fixed in the elevator shaft.
- the elevator system 1 can include several mounting brackets, each of these mounting brackets being installed separately on a different one above the lowest floor 10.1 lying floors 10.2, 10.3, 10.4 is fixed.
- the guide rail 3 or a guide rail segment fixed to the mounting bracket 30 can be placed on the shaft floor of the elevator shaft 4, in particular supported by this shaft floor.
- the floor fixing section 15, which is preferably formed by a cross member 7, is completed by a support wall section 13 designated 13.
- This support wall section 13 forms a vertical stop which rests on the door-side shaft wall 12.
- the shaft door 20 can also, for example, have coupling elements 24 for mechanical coupling with a device arranged on the elevator car 5 (not shown) coupling unit.
- the elevator car 5 may include a car door having a door drive motor.
- This door drive motor is intended, for example, for a synchronous opening/closing of the shaft door coupled to the car door and, if necessary, also for unlocking the car door and/or the shaft door.
- the coupling unit mentioned therefore fulfills the purpose of establishing an operative connection between the door drive motor and the shaft door 20. Accordingly, such coupling elements 24 protrude into the shaft space or the cross-sectional area of the elevator shaft 4.
- the shaft door 20 is arranged exactly in the vertical projection above the floor fixing section 15.
- FIG. 3 shows a mounting bracket 2 for an elevator system of the type described above.
- the mounting bracket 2 includes the cross member 7 and two side members 8 and 9 running at right angles to the cross member 7.
- a guide rail 3 is attached or can be attached to the ends of these side supports 8, 9.
- the mounting bracket 2 includes the floor fixing section 15, which is arranged along the cross member 7 for directly fixing the cross member 7 on a floor.
- the mounting bracket 2 can be fixed with screws 26 or similar fastening elements to be anchored in the floor.
- Mounting openings 19 created by holes or bores are arranged in the floor fixing section 15.
- the mounting bracket 2 can be fixed to the floor in an adjustable manner.
- a washer 29 can be used for adjustable fixation.
- Adjustment points 27 enable adjustment of further mounting brackets 2 arranged in the elevator shaft using exemplary plumb lines or comparable directional elements how to align the mounting bracket 2 suitable laser beams.
- the side beams 8, 9 and the cross beam 7 are each designed as rigid bent parts made of a metal sheet (eg sheet steel). Instead of the multi-part structure, the mounting bracket 2 can also be designed in one piece and created from a single or common sheet metal blank.
- the cross member 7 has a vertical support wall section 13 adjoining the floor fixing section 15 and created by a fold as a stop to the door-side shaft wall.
- the respective side support 8, 9 has a horizontal web section 17 and a vertical web section 16.
- the information on orientation refers to the situation after installation.
- the vertical web section 16 is connected in one piece to the horizontal web section 17 via a fold.
- the two web sections 16 and 17 extend from the cross member 7 to the guide rail.
- the support wall sections 13 are arranged at the front end of the side supports 8, 9.
- the rail fastening section 14 In the present case, it adjoins the horizontal web section 17 at a right angle and is connected to the horizontal web section 17 via a fold.
- the floor fixing section forms
