Definitions
- the present invention relates to a drive device for movement in the opposite or contrarative direction, capable of application in different fields of industry, in particular for the control of elevator doors, but also valid for building doors, of vehicles and in general for any door with two leaves with central opening by sliding of the two leaves in opposite directions, these being able to describe any straight, curved or combined trajectory.
- Various devices of this type are known, they include arms and articulations which rarely happen to be centered with the geometric center of curvature of the trajectory, the typical case being the arc of a circle, limiting the possibilities of opening the mechanism and still most of the time these devices need a traction system which takes up a considerable volume and which limits their applications when the available space is not sufficient.
- a mechanism of this type is known, marketed by the company SELCOM SpA, Vedole-Colorno (Italy), which comprises two belt transmissions each driving the control arm of a leaf of the door of an elevator of a circular cabin.
- the two transmissions are arranged in the same vertical plane which is parallel to the chord of the door opening arc.
- Each belt is connected to a socket which slides along the corresponding arm during the pivoting thereof, so that the lever arm of the socket relative to the pivot center of the control arm is variable, and especially that this speed is maximum when the leaves reach or leave the closed position.
- Another disadvantage is that this mechanism does not allow a wide opening angle of the door. In practice, this angle is limited to approximately 80 °.
- the width of the door opening is significantly smaller than the interior width of the car. In some cases, this may prevent access from this elevator disabled people in wheelchairs.
- the vertical arrangement of belt transmissions is cumbersome and may require an elevation of the top of the elevator shaft.
- European patent application No 93924493.5 in the name of Renolift Otis SA relates to a control mechanism, each control arm of which is associated with a secondary transmission having a flexible traction member which passes over two wheels with vertical axes and which is connected by an articulation at a determined point of the arm, a first of said wheels being driven by the motor by means of a primary transmission.
- the aim of the present invention is to remedy these drawbacks and to present a device based on a simple principle, applicable to all types of chains, belts, cables or the like, which can be shaped as necessary, which adapts to any linear movement, curve or combined, which is of millimeter precision, which gives maximum opening (up to 94% of diameter), silent operation, self-lubricating, practically wear-free, maintenance-free, with minimal motorization and very advantageous manufacturing.
- the device which is the subject of the invention comprises a running rail which collaborates with rolling discs supporting the leaves, a motor driving a driving wheel and a traction element characterized in that the traction element is an elongated endless element retained in a groove of the slides made of self-lubricating material parallel to each other and to the running rail which collaborates with the rolling discs integral with the elongate traction member, driven by the movement of the driving wheel.
- the slides can be in the same plane, which makes it possible to use a standard commercial chain or else superimposed, with the advantage of having both the same radius of curvature.
- the slides as well as the rolling discs are made of polyethylene, the slides can describe a curved trajectory such as an arc of a circle, a straight line or a combination of the two.
- a standard chain can be used, but it will also be possible to take advantage of the existence of special chains with protruding axes which allow bending on an axis perpendicular to the direction of movement and possibly other elements such as than belts or cables.
- the device can be mounted on the ceiling or under the floor.
- the drawing shows, by way of example, two embodiments of the device which is the subject of the invention.
- FIG. 1 shows a side view of a first embodiment of the device with the slides in the same plane and where the rail and the rolling discs have not been shown,
- FIG. 2 corresponds to a top view of the device of FIG. 1,
- FIG. 3 shows a second embodiment of the device, in which the two slides are superimposed, the rail and the pucks not also being shown,
- FIG. 4 is a top view of the device of FIG. 3, and
- Figure 5 shows us a section along the line VV of Figure 2, in which have been added all the elements necessary to illustrate the way in which a door leaf is hung.
- the slides 1 collaborate with the elongate elongate element, in this case a chain 2 which is driven in its movement by a drive wheel or pinion drive 3 with the assistance of a motor 4.
- the chain 2 rotates around two idler sprockets 5 and maintains its tension by the presence of a tensioning sprocket 6.
- the slides 11 are superimposed.
- the elongate element in this case is a special chain 21 with projecting axes which can also bend in a plane tangential to the slides 11.
- the rest of the elements of this configuration namely drive pinion 31, motor 41, return gears 51 and tensioning pinion 61, play the same role as that defined in the first embodiment described.
- FIG. 5 A detail of the device for controlling a door is shown in FIG. 5. According to the preferred embodiment, it shows us how the chain 2 is integral with the two rolling discs 7.
- FIG. 5 For reasons of simplification, only one puck has been shown in FIG. 5.
- the pucks 7 move in the direction opposite by rolling on a rail 8 located next to the slides 1.
- These rolling pucks collaborate with a fixing element 9 which makes the assembly with the leaf 10 of the door which will be driven by the movement.
- the chain has a reinforcement which prevents it from leaving the groove of the slides, it must be introduced by a side and remains inside the groove for the duration of its work.
- the slides describe arcs of a circle, but it is entirely possible to envisage another embodiment in which the slides while remaining adjacent could describe a straight line and even form an angle in the middle.
