Definitions

• the present invention relates to a car door for lifts and/or elevators, of the type comprising at least a pair of wings with telescopic opening, each of which is integrally connected to a corresponding carriage able to slide on a guide.
• the present invention further relates to a floor door for lifts and/or elevators. It is well known that, in the case of automatically opening doors constructed with sliding wings, each wing is integral to a carriage able to move along a guide usually positioned above the car door.
• the shape of the guide conforms to the trajectory followed by the sliding wings, the latter being integral with the carriage.
• the movement of the carriage is obtained by means of a positive drive belt, or a chain, connected to a motor or to a gear motor and mounted on one or more pulleys fastened to a plate positioned in correspondence with the sliding guide of the carriage.
• the transmission of motion, from the motor to the carriage takes place by means of the interposition of a plurality of mechanical linkages able to transform the rotary motion of the motor into a linear motion, useful to drive the carriage along the guide.
• An aim of the present invention is to propose a car door and a floor door provided with telescopic wings having high aesthetic value.
• An additional aim of the present invention is to provide a car door and a floor door within the context of a simple, rational and reliable constructive solution. Said aims are fully achieved by the car door and by the floor door of the present invention, which are characterised by the content of the claims set out below.
• FIG. 1 shows a top view of a section of a car door associated with a floor door, both in accordance with the present invention
• FIG. 2 shows a front view of means for actuating the car door of
• FIG. 3 shows an enlarged view of a constructive detail of the actuating means shown in Figure 2.
• the car door 1 comprises two pairs of telescopic wings 3, each of which is integrally connected to a corresponding carriage 4 able to slide on a guide 5 positioned above an entrance threshold of the car.
• the guide 5 is substantially curvilinear to allow the wings 3 to translate telescopically, according to a substantially curvilinear trajectory which preferably conforms to a circumference arc.
• the wings 3 have a substantially curvilinear external development, with radius of curvature preferably constant and equal to a radius of curvature of the guide 5.
• the wings 3 have central telescopic opening, although, in an alternative embodiment not shown herein, curvilinear wings with lateral opening may be installed.
• the car door 1 is provided with actuating means comprising a cable 6, or a belt, connected to the carriage 4 to drive it along the guide 5.
• the actuating means are provided with at least a tensioning element 7 associated to the cable 6, to adjust its tension.
• the tensioning element 7 is integrally fastened to an appendage 8 of the car and it is originally able to rotate about an axis, which is substantially vertical in this specific case, to adapt the cable 6 to the curvilinear profile of the guide 5.
• the appendage 8 is constituted by a vertical plate positioned above the car.
• the cable 6 has a first end 6a keyed onto a pulley 20 able to move along the sliding guide 5 of the carriage 4 and a second end (not shown) keyed onto a pulley integrally associated with the carriage 4.
• the tensioning element 7 comprises a square 9 fastened to the appendage 8 of the car and a body 10 substantially "U" shaped and hinged on the square 9.
• the body 10 has a pair of expansions 10a, 10b facing each other, to each of which is fastened a portion of cable 6, and it is provided with means for adjusting the tension of the cable itself.
• Said means can be associated to at least one of said expansions 10a, 10b and comprise at least a helical spring 11 coaxial to the cable 6 and acting on one of said expansions.
• the tensioning element 7, rotating about a vertical axis passing through the hinge point situated on the square 9, is able to compensate for the curvilinear profile of the guide 5, allowing to maintain a correct tension of the cable 6, both during the opening and the closing of the wings 3.
• the floor door 2 comprises wings 12 with central telescopic opening and having curvilinear external development.
• the wings 12 too are integrally connected to corresponding carriage able to slide on a guide (not shown herein) positioned above the threshold of the car.
• the opening and closing of the wings 12 are synchronised with those of the wings 3 of the car door 1 and commanded thereby.
• the actuation of the doors is accomplished by an actuation assembly (not shown) comprising an electric motor, preferably of the reluctance type, and a plurality of mechanical transmissions to transmit the motion of the engine to the cable 6 and thence to the carriage 4.
• an actuation assembly (not shown) comprising an electric motor, preferably of the reluctance type, and a plurality of mechanical transmissions to transmit the motion of the engine to the cable 6 and thence to the carriage 4.
• the actuation assembly can be positioned substantially side by side or below the car.
• the actuation assembly is positioned below a treading plane of the car, which shall therefore be provided with an inspection manhole, necessary for servicing.
• the invention achieves the important invention of conferring a considerable aesthetic value to the lift apparatus, adding value to the environment and/or the spaces within which it is installed.
• car doors and floor doors in accordance with the present invention are particularly well suited to be installed on lifts and/or elevators of the panoramic type, in which case they can even be made of transparent material, for instance glass.
