Abstract
Description
- The present invention relates to an apparatus for synchronising the movements of door panels as defined in the preamble of
claim 1. - In telescoping elevator doors with door panels suspended by means of rollers running on a runner rail, the synchronisation of the door panels is often implemented by adapting the movements of the fast and slow door panels to each other using e.g. a rigging that halves the speed of the fast door panel. Such a rigging usually comprises a driving rope and at least two rope pulleys.
- From publication DE A 1456404, a solution is known in which the synchronisation of the door panels is implemented using a driving rope running in a rope groove in the door supporting roller. In the apparatus presented in DE A 1456404, the door supporting roller is pressed against a roller race with a force depending on the weight of the door. Similarly, the roller is pressed against the driving rope with a force depending on the tightness of the rope. As the grooves in the supporting roller determine different perimeters, some sliding of the roller relative to the synchronising rope or the supporting rail necessarily occurs, causing wear of the roller. Even if the rollers are manufactured with the same designed perimeter of the grooves, small differences in perimeter may arise. Vibration of the door panels is also probable, especially if the friction forces in the roller with respect to the supporting rail and to the driving rope are nearly equal.
- Relating to the synchronisation of the movements of the door panels of an elevator door, a new solution for implementing the synchronisation using a rope, belt or similar rigging is presented. The apparatus of the invention is characterized by what is said in the characterization part of
claim 1. Other embodiments of the invention are characterized by what is presented in the other claims. - The advantages achieved by the invention include the following:
- The invention can be implemented without separate pulleys for a rope, belt or equivalent, thus reducing the manufacturing costs of the door. Savings are made in both materials and amount of work.
- The door has a simpler structure and the layout of its parts can be made clearer as the door comprises fewer separate parts.
- Expressly the fact that the synchronising means is passed over counter rollers means avoiding the problem that, as the grooves in the supporting roller determine different, sometimes just slightly different perimeters, some sliding of the roller relative to the synchronising rope or the supporting rail necessarily occurs. During normal movement of the door, the counter roller need not be pressed with a substantial force against the roller race. Thus, since the force is practically null, the frictional interaction between the roller race and the counter roller is also null. Therefore, no wear occurs even if the peripheral speed of the roller circumference on the race should differ from the speed of movement of the roller.
- In the following, the invention is described by the aid of a few application examples by referring to the attached drawings, in which
- Fig. 1
- presents the overhead beam of a door implemented according to the invention,
- Fig. 2
- presents the door of Fig. 1 as seen from a different direction,
- Fig. 3
- presents a roller provided with a rope groove, and
- Fig. 4
- presents another roller provided with a rope groove.
- Figures 1 and 2 illustrate an
overhead supporting beam 1 for a door implemented according to the invention and the suspension of thedoor panels fast door panel 12. Fig. 1 shows the cross-sectional form of the overhead beam and the placement of thepanel supporting rollers 2 and theircounter rollers beam 1. Formed in the supporting beam are roller races 4,5 for therollers upward stop face 6 for the supportingrollers 2 and adownward stop face 7 for thecounter rollers rollers plates overhead supporting beam 1 is as follows. The roller races 4,5 are shaped in the form of a flat-backed letter C, with their open sides facing towards opposite sides of theoverhead supporting beam 1. The upper C-shape 4 starts directly from the upper cleat of the lower C-shape 5. The stop faces 6,7 on the roller races 4,5 consist of the curved upper and lower surfaces of the C-shapes. Starting from the upper cleat of the upper C-shape, theoverhead supporting beam 1 is so bent that it again continues upwards. Theupper part 10 of theoverhead supporting beam 1 can be provided with one or more elbows to stiffen the beam structure and/or to produce a box-like shape. - At least the supporting
rollers 2 and possibly also thecounter rollers curved stop faces counter rollers 3a mounted on the supportingplate 9 of theslow door panel 13 are provided withrope grooves 31, through which thesynchronising rope 32 is passed. Thesynchronising rope 32 forms a loop which at onepoint 33 is immovably fixed to the roller race 5 by means of afixture 36 or otherwise immovably fixed relative to thebeam 1 and at anotherpoint 34 to afixture 35 on thefast door panel 12. Thesepoints slow plate 9 when the door is opened or closed because they are attached to parts of the loop that move in opposite directions. Therefore, thefast door panel 12 with its supportingplate 8 and theslow door panel 13 with its supportingplate 9 move in synchronism aside from the door opening and back to close the door opening. Adriving gear 11 drives abelt 17 which further moves the supportingplate 8 supportingdoor panel 12 by means of anintermediate piece 18. - Fig. 3 presents a
roller 3a. The bottom of the groove for the roller race is provided with arope groove 31. Fig. 4 presents another type of aroller 103a with arope groove 131. Therope groove 131 is placed on abellying 104 at one side of the roller that does not come into contact with the roller race engaged by the roller. Rollers with a rope groove are also applicable as door supporting rollers and they can be used to pass the synchronising rope, although in a practical application it would seem to be more advantageous to pass the synchronising rope over the counter rollers. When rollers with a rope groove are used as counter rollers, they need not necessarily be provided with a groove for the roller race but only with a groove for the rope. - It is obvious to a person skilled in the art that the embodiments of the invention are not restricted to the examples described above, but that they may instead be varied in the scope of the claims presented below. For instance, instead of using a synchronising rope running in rope grooves, the invention can be implemented using a belt or a similar synchronising means which has a flexibility resembling that of a rope or belt and is capable of guided motion on rollers. The guide used to guide a belt or the like differs from a rope groove in shape, but the function of the shape of the guide made in the roller is the same, i.e. to keep the belt or the like on the roller.
