Definitions
- the present invention relates to the field of elevator installations intended to be mounted in buildings or buildings, inside or outside thereof, and relates to a small elevator installation.
- an elevator is a device that makes it possible to move people or objects in height by serving defined levels or floors by means of a cabin that moves in a vertical duct arranged at the inside or outside a building or building.
- An elevator installation generally comprises a vertical elevator shaft with sheath walls, a shaft ceiling and a shaft bottom, an elevator car supported by a vertical arcade or stirrup structure guided in vertical motion.
- the sheath by cab guides, a drive motor, such as a permanent magnet electric motor, which actuates a driving pulley driving by adhesion at least one elongated member of hanger, cable-type, belt or chain, which is hanging the arch and a counterweight.
- the latter has the function to allow in particular to counterbalance and balance the load of the cab, to increase the adhesion of the cables on the drive pulley or reduce the power required to drive the cabin moving in the sheath.
- Cabin guides are generally constituted by two guide rails, or other rigid guide segments, forming a guide plane extending substantially vertically along the stroke of the cabin, the cabin then sliding vertically between said rails with slides integral with the arch structure and each sliding support on the inner or outer face of said guide rails.
- the counterweight meanwhile, is guided by counterweight guides usually consisting of two guide rails, between which moves the counterweight, extending vertically in a plane generally substantially parallel or perpendicular to the guide plane of the cabin.
- the engine is located in the upper part of the shaft, apart from the sliding system of the cabin and the counterweight, in a room or a machine room located (e) above the sheath and the last floor, especially outside the building.
- the manufacturers have proposed elevator installations without room or machine room and have developed elevator installations to minimize its bulk.
- the elongated hanger member are driven via halyard pulleys, fixed on the cab or on the yoke and / or on the counterweight, to divide the load and d use a motor and a drive pulley of smaller dimensions.
- hauling pulleys increase the assembly and maintenance time and their rapid rotation generates, on the one hand, vibrations and, on the other hand, a significant wear of said hauling pulleys and elongated hanger members they receive .
- these haulage pulleys in particular a large number of haulage pulleys, substantially reduce the efficiency of the installation and generate additional space in the duct meeting current demands to reduce the size of elevator installations. .
- the engine in the upper part of the sheath, it causes noise pollution for apartments on high floors and the operator who intervenes in the lower part of the sheath for maintenance and maintenance of the elevator does not see the engine that is hidden by the cabin.
- the installation of a motor and its accessories in the upper part of the sheath is long and not easy and maintenance interventions are binding for the operator who can easily access the engine and safely.
- the engine In the case where the engine is located in the lower part of the sheath, it is exposed to the risk of flooding, especially when it is placed in a bowl forming a portion of the sheath extending substantially from the lower threshold of the race from the cabin to the bottom of the shaft.
- the placement of the drive motor in the sheath, in the upper part or in the lower part of the sheath presents a risk for the maintenance operator who can be crushed by the cabin during an ascent or descent abnormal of the cab depending on whether the operator intervenes in the upper or lower part of the sheath.
- US 6 397 975 B relates to an elevator installation comprising a cabin supported by an arch structure, an elevator shaft defined by four sheath walls, namely a rear wall, a front wall, a wall left side and a right side wall coming from a square with said rear walls and front and a guide assembly, located between the right side wall and the cabin and having vertical guide rails for guiding vertical translation against a counterweight and the structure arcade of the cabin.
- the counterweight is mounted between two guide rails in a sliding plane located in the immediate vicinity of the right side wall, that is to say leaving a gap between the latter and the displacement plane of the counterweight.
- Such an installation also comprises a drive unit comprising a motor and a driven driving pulley inclined with respect to the right lateral wall, which drive unit is arranged in one of the corners of the sheath, which outside the vertical space extending between or separating the guide assembly and the right side wall or guiding field of the counterweight and the cabin. Furthermore, the drive unit is partially embedded in a reservation made or dug in said corner, that is to say both in the right side wall and in the rear wall.
- the position of the drive unit in the corresponding corner of the sheath occupies a space that prevents any sliding door opening from the opposite access of the cabin or requires large duct dimensions, meeting the constraints current, to clear a sliding space of the doors between the cabin and the drive unit.
- the present invention aims to overcome these disadvantages by providing an elevator installation occupying a reduced space in the duct meeting the current architectural and safety requirements, and allowing, in particular, to obtain assembly times lower than those of the installations.
- the present invention relates to an elevator installation intended to be mounted in a building or a building, inside or outside thereof, comprising a sheath Elevator defined by vertical duct walls, a duct bottom and a duct ceiling, an elevator car supported by an arcade structure guided by cabin guides, such as guide rails or similar segments, an engine drive unit driving a driving pulley driving at least one elongated suspension member, of the cable, belt, chain, lifting or the like type, for vertically displacing in said sheath said arch structure and a counterweight guided by counterweight guides , said cab guides and counterweight guides forming a guide assembly and characterized essentially in that:
- the guide assembly extends, along the course of the car, between one of the sheath walls or main sheath wall and said cabin,
