Definitions

• the invention relates to an elevator system with a mounting bracket fixed in the region of a shaft wall on the door side of an elevator installation.
• Elevator systems include an elevator car, which elevator car is usually arranged to be movable along a vertically aligned elevator shaft.
• Guide rails for guiding the elevator car are arranged along the elevator shaft.
• the guide rails essentially consist of individual guide rail segments, which are fixed in the elevator shaft using mounting brackets.
• EP 1 321 416 discloses a guide rail assembly 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 shaft wall on the door side.
• the mounting bracket has two legs that extend from the ends of the transom into the elevator shaft. Guide rails or guide rail segments are fastened to these legs. Both the transverse beam and the legs are therefore arranged within the cross-sectional area of the elevator shaft, as a result of which the free cross-sectional area of the elevator shaft that is suitable for the mobility of the elevator car is reduced.
• the cross-sectional area of the elevator shaft means the area for the hollow space defined by the elevator shaft as seen in the top view or in the vertical direction.
• the invention is based on the object of proposing an elevator system whose installation ensures increased safety for the fitter.
• an elevator system with a mounting bracket aligned in the region of the shaft wall on the door side, guide rails for guiding an elevator car arranged in an elevator shaft being fixable or fixed on the mounting bracket, the mounting bracket preferably using at least one Floor fixation section is fixed or fixable for fixing the mounting bracket, wherein the floor fixation section is arranged or can be arranged on a horizontal surface of the floor.
• the invention is based on the finding that only the arrangement of the shaft doors is decisive for the positioning of all essential components of the elevator car that affect the ability to move the elevator car. Accordingly, the mounting bracket for fixing the guide rails in the elevator shaft must be aligned with respect to the installed or to be installed shaft door. Consequently, it is sufficient that the mounting bracket is or can be connected, in particular fixed or can be fixed, exclusively in one area of the essentially horizontally oriented floor area.
• the fitter can fix the mounting bracket exclusively from the floor area, so that additional security measures are possible, for example closing the wall opening provided for the installation of the shaft door between the floor and the elevator shaft, for example by inserting an additional barricade device different from a shaft door. In this way, the fitter can be prevented from penetrating or possibly falling into the elevator shaft. In other words, it is not necessary for the fitter to carry out work himself in the elevator shaft to fix the mounting brackets.
• the fixing of the mounting bracket to the horizontal surface of the storey floor can be designed in such a way that the mounting bracket is fixed or can be fixed directly to the concrete of the storey floor.
• the fixing of the mounting bracket and the part of the mounting bracket located in the vertical alignment of the floor can essentially be cast into the screed, for example.
• the mounting bracket comprises a cross member and two side members, preferably at right angles, extending from the cross member, a first of the side members being disposed at a first end of the cross member and the second of the side members being disposed at a second end of the cross member, the cross member being substantially within the floor (and more precisely within the Cross-sectional area of the floor) arranged or can be arranged.
• the cross-sectional area of the floor below means the area seen in the top view or in the vertical direction, which is occupied by the floor.
• the cross-sectional area of the floor does not relate to a cavity.
• the storey floor or the cross-sectional area of the storey floor consequently also specifies the floor-side area that can be walked on by passengers, which ends at the door-side shaft wall. Accordingly, exclusively fixing the mounting bracket to the horizontal section of the storey floor allows the cross member to take up almost no cross-sectional area of the elevator shaft itself. In other words, this means that the cross member essentially does not protrude into the cross-sectional area of the elevator shaft.
• the main components (i.e. the cross member, the side member or members) of the mounting bracket can have the following purposes:
• the cross member comprising the at least one floor fixing section serves to attach the mounting bracket to the elevator shaft.
• the guide rails are fixed or can be fixed to the side supports.
• the crossbeam can have a fold as a stop for the shaft wall on the door side, which fold is preferably arranged or can be arranged on the end of the storey floor delimited by the elevator shaft.
• the bevel which preferably extends in the horizontal direction between the side supports, can close off the transverse support from the elevator shaft.
• the fold can thus be the only segment of the crossbeam which—at least in the installed state—is located or is arranged within the cross-sectional area of the elevator shaft.
• the mounting bracket can be designed integrally or be formed from several elements that can be fixed to one another.
• the side supports and the cross support can be formed by connectable elements.
• the side supports can be arranged or arranged within the cross-sectional area of the elevator shaft. In this way, guide rails can be fixed within the cross-sectional area of the elevator shaft, for example at the ends of the side supports arranged in the elevator shaft, and only the components of the mounting bracket necessary for positioning can be arranged within the cross-sectional area of the elevator shaft.
• the at least one floor fixing section is designed in such a way that the mounting bracket is fixable or fixable in an adjustable manner.
• Adjustably fixable or fixable means that such a pre-fixation is made possible before a final alignment and subsequent final fixation of the mounting bracket. This can be achieved, for example, by means of a screw connection, which enables the mounting bracket to slide horizontally in its pre-fixed state.
• the storey fixing section which is designed as a passage opening, for example, can be designed to be larger than required by the dimensions of the screw, by means of which the mounting bracket is fastened or can be fastened to the floor.
• a base plate designed according to a washer causes a pre-fixing or final fixing of the mounting bracket on the floor due to the degree of its pressing by means of the screw on the mounting bracket.
• Such an adjustability allows a pre-fixing of the mounting bracket on the floor and a subsequent alignment and final fixing of the mounting bracket in the elevator shaft using aligning elements that can be arranged in the elevator shaft.
• the mounting bracket has at least one adjustment point for aligning the mounting bracket within the elevator system.
• Such an adjustment point can, for example, be designed as a passage point for a directional element running within the elevator system, for example a plumb line or a laser beam. Consequently, when installed in the elevator system, the adjustment point is formed within the cross section of the elevator shaft. In other words, this adjustment point is formed outside of the vertical alignment of the bottom of the shaft.
• the mounting bracket preferably has two adjustment points. In this way, the mounting bracket, which is preferably pre-fixed, can finally be aligned in the elevator shaft by means of alignment elements. Finally aligned means that the mounting bracket is in the exact position that the guide rails or guide rails to be fixed to the mounting bracket Guide rail segments ensure mobility of the elevator car, which can be guided on the guide rails, within all dimensional tolerances.
• Such aligning elements are used in order to correctly align components to be installed in the elevator shaft, such as shaft doors or mounting brackets, with respect to one another in relation to the travel direction of the elevator car intended later.
• Such directional elements can be formed, for example, by plumb lines or laser beams.
• the mounting bracket has two floor fixing sections.
• the mounting bracket can be fixed on the floor surface by means of these floor fixing sections. This enables the mounting bracket to be securely aligned in the elevator system.
• the shaft door that can be provided for installation on the mounting bracket comprises at least one door leaf.
• Essential components of the shaft door can include this at least one door panel of this shaft door and/or a door sill and/or at least one door panel guide rail for guiding this at least one door panel.
• the shaft door can contain coupling elements which are necessary for the mechanical coupling of the car door to the shaft door. These coupling elements can protrude into the cross-sectional area of the elevator shaft.
