Abstract

The present invention relates to an activation system comprising: - A fixed protection plate (10) on which actuation means based on a reset coil (1) and a retaining coil (2), as well as release means in an aligned arrangement are attached. - Movable wedge means activated by the actuation means and wherein these movable wedge means are in a parallel arrangement with respect to the actuation means. - One or two wedge rollers (6) depending on whether it is for a one-way safety device system or for a two-way safety device system, respectively, A compact system that can adapt to existing safety devices is achieved. The electromechanical actuation is executed vertically, which dispenses with additional levers, decreases susceptibility to failure and means that the reset and retaining coils are smaller.

Abstract

Drive comprising a set of safeties that can be bidirectional or unidirectional. In the case of the bidirectional system, it is formed by two wedge rollers (1) and (2) that run through oblong grooves (11) and (12) respectively provided in a protective plate (16). The wedge rollers (1) and (2) are assembled onto floating anchors (14) and (15) respectively, which anchors are linked together by means of a spring (5); on the other hand it comprises a drive assembly comprising a coil (3) where the transmission between the drive and the wedge assembly is carried out by means of a flexible transmission comprising two cables (7) and (8) joined at one of their ends to the drive assembly and at the other end to the floating anchors (14) and (15) on which the wedge rollers (1) and (2) are mounted. In addition, the bolts of the rollers (1) and (2) run through the oblong holes of a discriminating plate (6) which is responsible for separating the non-wedged roller from the guide. This system allows separate mounting of the wedge assembly with respect to the drive assembly.

Abstract

An actuator comprising an anti-fall safety gear assembly, either one-way or two-way. In the case of a two-way system, this is formed by two wedge rollers (1) and (2) which run in two oblong grooves (11) and (12) respectively, executed in a protective shield (16). The wedge rollers (1) and (2) are assembled on floating anchor points (14) and (15) respectively, these anchor points being linked together by means of a spring (5). In addition, it comprises an actuator assembly comprising a coil (3) where the transmission between the actuator and the wedge assembly is executed by means of a flexible transmission comprising two cables (7) and (8) attached by one of their extremities to the actuator assembly and by their other extremity to the floating anchor points (14) and (15) whereon the wedge rollers (1) and (2) are installed. Furthermore, the pins of the rollers (1) and (2) run in the oblongs of a discrimination plate (6) whose function is to separate the unwedged roller from the guide. The separate installation of the wedge assembly and the actuator assembly is permitted.

Abstract

The electromechanical activation of a bi-directional emergency stop device comprises a supporting plate (22) equipped with retaining means, intermediate transmission means for the movement toward two articulated levers (5) at the free end of which a wedge roller (7) is attached by means of a roller cam (20), where each articulated lever (5) rotates with regard to one of its ends, and the intermediate transmission means comprise a linearly movable carriage (3) linked to the mobile end of the retaining means, where the movable carriage is in turn articulatedly linked to an articulated carriage (4) destined for the transmission of the movement to the articulated levers (5) by means of transmission connecting rods (6) which are articulatedly joined to an intermediate point of the articulated levers (5), equipped with a compensating spring (9) for the weight of the device and a recovery spring for the articulated levers.

Abstract

Electromechanical activation of a unidirectional emergency stop device for a lift comprising a support plate (13) in which there are electromechanical retention means and mechanical means consisting of a connecting rod displaced by the activation spring, and wherein at the end opposite the activation means the connecting rod is connected to an articulated lever (6), the articulated lever (6) having an articulated joint (6.1) with respect to which it rotates and, at its opposite end, a roller connecting rod (8) which in turn has a wedging roller (9) on its end that runs along a curved slot (10) formed in the protective plate, and wherein the connecting rod that moves the articulated lever (6) is a compressible connecting rod (5) consisting of two plates connected to each other via a compression spring (5.1).

Abstract

The invention relates to a system comprising two sub-assemblies, namely one sub-assembly positioned to the right of the frame and one sub-assembly positioned to the left of the frame, in which each sub-assembly (1) comprises a support base (2) for safety means and, optionally, guide means (3) which are disposed on either the support base (2) or on an additional support. The safety means disposed on the support base (2) of each sub-assembly take the form of a safety gear (4) and a linkage (5). In addition, a speed limiter (6) is disposed on the support base (2) of one of the sub-assemblies. With this system it is not necessary to adapt the longitudinal members of the frame to all of the safety components: safety gear, limiter, linkage and guide (slide shoe or roller guide shoe), and it is possible to reduce the number of components required for construction, thereby reducing the weight and cost thereof.

Abstract

The invention relates to a pergola intended for the rooftop of a building and for attachment of a wind generator, which includes a plurality of adjustable support columns (1), on the lower ends of which are hollows into which can be inserted adjustable auxiliary supports; there are also beams that link the upper ends of the support columns, defining at least one horizontal surface (9) on which to attach a wind generator (7), that has a base, a mast, a generator, a series of arms and wind blades, wherein it is possible to house a means of storing energy and a means of control under the pergola. The pergola constitutes an efficient and simple means of attaching a generator, and additionally forms a structure or construction that can be used for other purposes, such as an elevator machine room, a utility room, etc., and that can be adapted to any type of roof, and facilitates installation of the wind generator.

The invention relates to an integral system of corner brackets for an elevator frame, said system allowing an elevator frame to be produced using the corner brackets into which all of the dynamic elements required in an elevator frame have been incorporated, such as safety and guide systems. The system comprises two lower corner brackets which form part of the elevator frame and include the safety and guide systems. In addition, depending on the case, one or two upper angle brackets can be used, the heavy-duty part of the frame being integrated with the safety and guide equipment.

Abstract

The elevation system disassociates the suspension and traction functions and for this purpose has two pulleys; one suspension pulley for supporting the weight of the cabin itself and the counterweight, and another traction pulley, which only generates the force to move the imbalance existing between the cabin and the counterweight. The traction pulley can be directly connected to a motor (gearless) or connected to a reducer motor. Each pulley has suspension and traction cables which are independent of each other. The system of one suspension pulley and another traction pulley makes it possible to greatly reduce the motor size, to design the elevation system to the customer's taste, to rapidly include advantages in the installation and to improve the existing installations, while simplifying maintenance and at all times ensuring safety.
