Technical field of the invention
[0001] The invention relates to the field of elevators and more specifically to an actuation operator device for opening and closing elevator doors with at least one leaf, as well as an assembly formed by said operator device and a cabin door.
Background of the invention
[0002] Elevators are usually provided with an operator or actuation device that is responsible for simultaneously and automatically opening cabin doors and landing doors, when the cabin stops at said landing. These actuation devices are fixed to the cabin by means of a suitable support, the actuating mechanisms usually being arranged above the cabin doors. Said mechanisms are equipped with a laterally moveable driver carriage to which the cabin doors are associated, and with an extendable clutch which, in a certain position, connects the landing doors with the driver carriage, in order to enable the simultaneous and automatic opening or closing of the cabin doors and the landing doors, when the cabin reaches the stop position on said landing.
[0003] The driver carriage, which is conveniently guided, is usually associated with a drive belt that is driven by a return pulley which, when rotating in one direction or another, causes the carriage to move towards the opening position or towards the closing position of the doors, respectively. To do so, the required force must be transmitted to the return pulley so that the carriage, in the opening and closing movement thereof, drags the cabin doors of the landing. To do this, the actuation devices include an electric motor for this purpose, generally positioned above the elevator cabin so as not to increase the total width of the actuation device.
[0004] The operator supports, which are fixed to the elevator cabin, have considerable dimensions that protrude from the sides of the cabin and therefore define, to a large extent, the width of the elevator shaft required for installation. Thus, it would be desirable to have an operator device that would enable the distance that protrudes laterally from the cabin with the door leaves closed to be reduced, reducing the space required inside the shaft that houses the cabin door during travel of the elevator.
Description of the invention
[0005] In order to provide a solution to the aforementioned space problem of the elevator shaft, an actuation operator device for opening and closing elevator doors with at least one leaf is disclosed, comprising:
- an operator support to be fixed to the elevator cabin,
- a driver carriage to which at least one door leaf of the elevator cabin is associated,
- a horizontal guide along which, or along a section of which, the driver carriage is moveable;
- a clutch, fixedly attached to the driver carriage, comprising locking means for locking the cabin door and a male group of those formed by two clutch arms which, in a certain position, connects the landing doors with the driver carriage in order to enable the simultaneous and automatic opening or closing of the cabin door and the landing door, when the cabin stops at a landing,
- a rotation axle provided in the operator support, actuated by a motor and connected to a transmission system comprised in the operator support, transmission system to which the clutch is attached such that the rotation of the axle causes the horizontal movement of the clutch and the driver carriage in one direction or another depending on the direction of rotation of the axle.
[0006] In essence, the operating device is characterised in that the horizontal guide along which the driver carriage is moveable is a telescopic guide formed by a base guideway that is fixed to the operator support, and by at least one first telescopic guideway that is capable of being moved along and beyond the base guideway in a door opening position.
[0007] According to another feature of the invention, the driver carriage is fixedly attached to a first telescopic guideway that is moveable with respect to the base guideway.
[0008] According to a preferred variant of the invention, a first intermediate telescopic guideway is arranged between the base guideway and the first telescopic guideway (which is fixedly attached to the driver carriage), coupled to the base guideway and to the first telescopic guideway through respective sets of bearings.
[0009] According to another feature of this preferred variant, the base guideway has a substantially C-shaped cross-section inside of which the first intermediate telescopic guideway is coupled, which in turn has a substantially C-shaped cross-section and inside of which the first telescopic guideway is in turn coupled (which is fixedly attached to the driver carriage). The first telescopic guideway has a substantially C-shaped cross-section but arranged with the open side thereof oriented towards the open side of the first intermediate telescopic guideway. First sets of bearings are arranged between the two upper wings of the base guideway and of the first intermediate telescopic guideway, and between the two lower wings of the base guideway and of the first intermediate telescopic guideway. Second sets of bearings are arranged between the two upper wings of the first intermediate telescopic guideway and of the first telescopic guideway that is fixed to the driver carriage, and between the two lower wings of the first intermediate telescopic guideway and of the first telescopic guideway (fixedly attached to the driver carriage).
[0010] According to another preferred variant of the invention, several first intermediate telescopic guideways are arranged between the base guideway and the first telescopic guideway (fixedly attached to the driver carriage), coupled to each other through respective sets of bearings, one of the first intermediate telescopic guideways being coupled to the base guideway through first sets of bearings, and another of the first intermediate telescopic guideways being coupled to the telescopic guideway that is fixed to the driver carriage through respective second sets of bearings.
[0011] According to another preferred variant of the invention, indicated for those cases wherein the lift doors have at least two leaves that move away from and towards each other for opening and closing the door, the operator device further comprises:
- a driven carriage, to which at least one second door leaf of the elevator cabin is associated, moveable along the horizontal guide or a second section thereof;
- an additional transmission system, comprised in the operator support, fixedly attached in one portion to the driver carriage and fixedly attached in another portion to the driven carriage, capable of transmitting the displacement movement from the driver carriage to the driven carriage, but in an opposite direction;
[0012] According to another feature of this variant for doors with at least two leaves, the driven carriage is fixedly attached to a second telescopic guideway that is moveable with respect to the base guideway.
[0013] According to a first embodiment of this variant, a second intermediate telescopic guideway is arranged between the base guideway and the second telescopic guideway (which is fixedly attached to the driven carriage), coupled to the base guideway and to the second telescopic guideway through respective sets of bearings.
[0014] A preferred feature of this first embodiment is that the base guideway has a substantially C-shaped cross-section inside of which the second intermediate telescopic guideway is coupled. In turn, the second intermediate telescopic guideway has a substantially C-shaped cross-section inside of which the second telescopic guideway (which is fixedly attached to the driven carriage) is in turn coupled. The second telescopic guideway has a substantially C-shaped cross-section but arranged with the open side thereof oriented towards the open side of the second intermediate telescopic guideway. Third sets of bearings are arranged between the two upper wings of the base guideway and of the second intermediate telescopic guideway, and between the two lower wings of the base guideway and of the second intermediate telescopic guideway. Fourth sets of bearings are arranged between the two upper wings of the second intermediate telescopic guideway and of the second telescopic guideway (fixed to the driven carriage), and between the two lower wings of the second intermediate telescopic guideway and of the second telescopic guideway (fixed to the driven carriage).
[0015] According to a second embodiment of this variant for doors with at least two leaves, several second intermediate telescopic guideways are arranged between the base guideway and the second telescopic guideway (which is fixedly connected to the driven carriage), coupled to each other through respective sets of bearings. One of the second intermediate telescopic guideways is coupled to the base guideway through third sets of bearings, and another of the second intermediate telescopic guideways is coupled to the telescopic guideway that is fixed to the driven carriage through respective fourth sets of bearings.
[0016] According to a preferred feature of the object of the invention, also valid for any of the variants described, in the closed door position, the operator support protrudes on each side of the closed cabin door by a distance (D) comprised between 2% and 15%, preferably between 2% and 10%, with respect to the total of the distance occupied by the closed door (P).
[0017] According to another additional feature of the object of the invention, valid for any of the variants described, in the open door position, the two clutch arms of the clutch and more than 50% of the total length of the driver carriage are located on one side of the operator support, outside of the same, while in the closed door position, the clutch and the driver carriage are completely located between the vertical sides of the operator support and, particularly, within the free passage distance (PL) of the door.
[0018] According to another additional feature of the object of the invention, valid for any of the variants described, in the open door position, more than 50% of the total length of the driven carriage is located outside the operator support, to one side of the same, on the opposite side to the one wherein the two clutch arms remain, while in the closed door position, the driven carriage is located between the vertical sides of the operator support and, particularly, within the free passage distance (PL) of the door.
[0019] According to a preferred feature of the object of the invention, the length (L) of the operator support measured between the two vertical sides thereof is between 4% and 20% greater than the free passage distance (PL) of the door.
[0020] According to another preferred feature of the object of the invention, the length (L) of the operator support measured between the two vertical sides thereof is only 100 mm greater than the free passage distance (PL) of the door. In conventional operator devices, for a central door with two leaves, the usual measurement of the length L of the operator support is 2PL + 50 mm (double PL plus 50 mm). Instead, according to the present invention, the measurement L is PL + 100 mm. Thus, for a PL of 700 mm, L is 1,450 mm in a conventional operator device, compared to an L of 800 mm (the operator support protrudes 50 mm, 7.14% with respect to the PL of 700 mm). For a PL of 900 mm, a conventional operator support has a length L of 1,850 mm, compared to 1,000 mm for the operator support of the operator device according to the present invention (it protrudes 5.55% on each side with respect to PL).
[0021] Other embodiments are not ruled out wherein the length (L) of the operator support measured between the two vertical sides thereof is only from 50 mm to 150 mm greater than the free passage distance (PL) of the door, which in itself represents a very considerable reduction compared to conventional operator supports.
[0022] According to a second aspect of the invention, an assembly of an operator device as described above, including all the variants thereof, and a cabin door with one or more leaves is disclosed.

Detailed description of the invention
[0024] Figs. 1, 2 and 3 show an actuation operator device 100 for opening and closing a elevator door with two sliding leaves 20 and 21, the operator support 101 of which is fixed to the upper front portion of a elevator cabin, the door being represented in a closed, semi-open and fully open door position, respectively.
[0025] Figs. 4, 5 and 6 show the components of the operator device 100 in greater detail, which, in addition to the operator support 101, comprise:
- a driver carriage 9 (driver carriage in English) to which the door leaf 20 of the elevator cabin is associated,
- a driven carriage 18 (driven carriage in English), to which the second door leaf 21 of the elevator cabin is associated, said driven carriage 18 being moveable along a second section of a horizontal guide 5;
- a horizontal guide 5 having a first section, on the left half (according to the drawings), along which the driver carriage 9 is moveable, and a second section, on the right half, along which the driven carriage 18 is moveable;
- a clutch 4 (known as clutch in English), fixedly attached to the driver carriage 9, comprising locking means 8 for locking the cabin door and a male group of those formed by two clutch arms 6 and 7 which, in a certain position, connects the landing doors with the driver carriage 9 in order to enable the simultaneous and automatic opening or closing of the cabin door and the landing door, when the cabin stops at a landing,
- a rotation axle 1 provided in the operator support 101, actuated by a motor and connected to a transmission system 2 comprised in the operator support 101, transmission system 2 to which the clutch 4 is attached such that the rotation of the axle 1 causes the horizontal movement of the clutch 4 and the driver carriage 9 in one direction or another depending on the direction of rotation of the axle 1; and
- an additional transmission system 13, comprised in the operator support 101, fixedly attached in one portion to the driver carriage 9 and fixedly attached in another portion to the driven carriage 18, capable of transmitting the displacement movement from the driver carriage 9 to the driven carriage 18 but in an opposite direction.
[0026] As Figs. 7 to 10 and 12 especially show, the horizontal guide 5 is a telescopic guide that extends beyond the two longitudinal ends of the operator support 101, for the sliding of the driver carriage 9 to the left (facing the drawings) and of the driven carriage 18 to the right, and with them, the sliding of the corresponding leaves 20 and 21 of the door.
[0027] The telescopic horizontal guide 5 is formed by a base guideway 51, fixed to the operator support 101, which preferably goes from the left end to the right end of said support. The telescopic horizontal guide 5 further comprises, on the left end, a first intermediate telescopic guideway 52 coupled to the base guideway 51, and a first telescopic guideway 53 fixedly attached to the driver carriage 9 and in turn coupled to the first intermediate telescopic guideway 52. At the right end, the telescopic horizontal guide 5 comprises a second intermediate telescopic guideway 54 coupled to the base guideway 51, and a second telescopic guideway 55 fixedly attached to the driven carriage 18.
[0028] Fig. 12 schematically shows how the first intermediate telescopic guideway 52 is arranged coupled between the base guideway 51 and the first telescopic guideway 53 through respective sets of bearings 61 and 62. In this way, the first intermediate telescopic guideway 52 moves by the action of the bearings 61 and 62, which rotate when the first telescopic guideway 53 that is fixed to the driver carriage 9 moves. Fig. 12 also shows the cross sections of the guideways involved. Thus, the base guideway 51 has a substantially C-shaped cross section inside of which the first intermediate telescopic guideway 52 is coupled, which in turn has a substantially C-shaped cross section and inside of which the first telescopic guideway 53 that is fixed to the driver carriage 9 is in turn coupled. As can be seen, the first telescopic guideway 53 has a substantially C-shaped cross-section but arranged with the open side thereof oriented towards the open side of the first intermediate telescopic guideway 52. The first sets of bearings 61 are arranged in particular between the two upper wings of the base guideway 51 and of the first intermediate telescopic guideway 52, and between the two lower wings of the base guideway 51 and of the first intermediate telescopic guideway 52. The second sets of bearings 62 are arranged between the two upper wings of the first intermediate telescopic guideway 52 and of the first telescopic guideway 53, and between the two lower wings of the first intermediate telescopic guideway 52 and of the first telescopic guideway 53. As can be seen, the wings of the different C-shaped profiles of the guideways are not flat, instead they comprise curvatures, in the form of folds or sinking, that collaborate with each other to retain the sets of bearings 61 and 62 between them.
[0029] At the right end thereof, the horizontal guide 5 has a telescopic configuration practically identical to that described in relation to the right end thereof. Thus, the second intermediate telescopic guideway 54 is arranged between the base guideway 51 and the second telescopic guideway 55 fixedly attached to the driven carriage 18, coupled to the base guideway 51 and to the second telescopic guideway 55 through respective sets of bearings. As regards the shape and orientation of the transverse profiles, the second telescopic guideway 55 has the same as the first telescopic guideway 53, and the second intermediate telescopic guideway 54 has the same as the first intermediate telescopic guideway 52.
[0030] In the example of operator device 100 shown in the figures, the telescopic horizontal guide 5 has, on each side, an intermediate telescopic guideway profile 52, 54 located between the base guideway 51 that is fixed to the operator support 101 and the respective telescopic guideway 53, 55 fixedly connected to the driver carriage 9 or to the driven carriage 18. However, it is contemplated that in other embodiments of the operator device 100, there will be several intermediate telescopic guideways coupled together, not just one.
[0031] In this way, on the left side, several first intermediate telescopic guideways are arranged between the base guideway 51 and the first telescopic guideway 53 (fixedly attached to the driver carriage 9), coupled to each other through respective sets of bearings. Obviously, one of the several first intermediate telescopic guideways will continue to be coupled to the base guideway 51 through first sets of bearings 61, and another of the first intermediate telescopic guideways will continue to be coupled to the telescopic guideway 53 that is fixed to the driver carriage 9 through respective second sets of bearings 62. The same applies on the right side, so that several second intermediate telescopic guideways are arranged between the base guideway 51 and the second telescopic guideway 55 (fixedly attached to the driven carriage 18), coupled to each other through respective sets of bearings.
[0032] The sequence of the opening movement of the door with two leaves 20 and 21 that is carried out in the operator device 100 represented in the figures is explained below.
[0033] Having detected that the elevator has reached a landing, the motor that causes the rotation axle 1 to rotate is activated, which causes the belt that is part of the transmission system 2 to move. The belt is arranged between the rotation axle 1 and a pulley 19 that is fixed to the operator support 101 at the opposite end of the rotation axle 1 (see Figs. 4 and 5). A belt clamp 41 (belt clamp in English) is fixed to the belt of the transmission system 2 and to the clutch 4, so that when the belt moves, the clutch 4 moves. As Fig. 4 shows, the clutch 4 comprises a portion with an essentially right-angled triangle shape at the right vertex of which is the attachment with the belt clamp 41. The clutch arm 7 is located just to the left of said triangular portion and below said portion the locking means 8 for locking the cabin door are arranged.
[0034] When the clutch 4 moves, its main function is to drag the driver carriage 9 therewith, to which it is attached by a fixing 42 or fixing points, in the opening direction. For its part, the driver carriage 9 is fixedly attached to the first telescopic guideway 53 through the fixing points 91, transmitting the movement and starting the opening. Moreover, as a secondary function, the clutch 4 causes the locking means 8 to rotate, unlocking and moving the clutch arms 6 and 7 to their opening position.
[0035] At the same time, as the driver carriage 9 moves, a fixing support 92 that is fixed to the driver carriage 9 transmits this movement to a tape or thin tubular duct that forms part of an additional transmission system 13 together with two pulleys between which it moves. To transmit the movement to the driven carriage 18, another support 181 is fixed to the driven carriage 18 and to the tape or to the fine tubular duct of the additional transmission system 13. The movement of the driven carriage 18 will thus be in the opposite direction to that of the driver carriage 9.
[0036] It is important to point out that the elements that make up the rotation axle 1, the pulley 19, the triangular portion of the clutch 4, the two pulleys of the additional transmission system 13 and the support 181, have been designed so that they do not protrude laterally from the vertical sides of the operator support 101, not even when the operator device is in the fully opened position of the door, that is, so that they are contained in the dotted lines marking the limits of the length L of the operator support 101 in Fig. 1. This design enables all these elements to be kept within these lateral limits of the operator support 101, while in conventional designs a much longer operator support is required that reaches the outer vertical sides of the leaves 20 and 21 of the door in the open position.
[0037] This allows the space required when the cabin door travels between landings to be reduced, since the operator support 101 only protrudes a little more than the leaves 20 and 21 of the door in the closed position, as seen in Fig. 1 comparing the small distance D that separates the length L of the operator support 101 with respect to the distance P that the closed door occupies. In the case represented in Fig. 1, the distance D is about 30 mm, which has to do with the number of telescopic guideways on each side of the horizontal guide 5. The more telescopic guideways there are between the operator support 101 and the driver carriage 9, or between the operator support 101 and the driven carriage 18, to make the door leaves 20, 21 of the elevator cabin slide, the smaller the distance D will be.
[0038] According to embodiments, the length L of the operator support 101 measured between the two vertical sides thereof is only 4% to 20% greater than the free passage distance PL of the door. Preferably, the L of the operator support 101 measured between the two vertical sides thereof is only 100 mm greater than the free passage distance PL. Thus, for a PL of 700 mm, L is 800 mm, which is considerably reduced compared to the L of 1,450 mm for conventional operator supports, wherein L is usually equal to 2PL + 50 mm (twice the PL plus 50 mm). Similarly, for a PL of 900 mm, the length L of the operator support 101 is only 1,000 mm, which is very short compared to 1,850 mm for a conventional operator support.
[0039] Fig. 1 also shows that in the closed door position, the operator support 101 protrudes on each side of the closed cabin door by a distance D comprised between 2% and 20%, preferably between 2% and 10%, with respect to the total distance occupied by the closed door P. In one embodiment of the invention, the leaves 20 and 21 of the closed door have a measurement P of 840 mm, a free passage distance PL of 800 mm, and the operator support 101 has an L of 900 mm, such that the distance D that protrudes is 60 mm, 3.57% with respect to the distance occupied by the closed door P.
[0040] Another advantage, which can be seen in Figs. 3 and 6, is that in the open door position, the two clutch arms 6 and 7 of the clutch 4 and more than 50% of the total length of the driver carriage 9 are located on one side of the operator support 101, outside the same (to the left when facing the drawings), while in the closed door position represented in Figs. 1 and 4, the clutch 4 and the driver carriage 9 are completely located between the vertical sides of the operator support 101 and, particularly, within the free passage distance PL of the door.
[0041] In the open door position represented in Figs. 3 and 6, more than 50% of the total length of the driven carriage 18 is located outside the operator support 10, that is, beyond the vertical sides thereof, on one side of the same, on the side opposite to the one wherein the two clutch arms 6 and 7 remain, while in the closed door position, the driven carriage 18 is located between the vertical sides of the operator support 101 and, particularly, within the free passage distance PL of the door. Some distances have been indicated in Fig. 6 showing how small the operator device 100 is. Considering a free passage distance PL equal to 800 mm, L/2 is equal to 450 mm (PL/2 + 50 mm); d67, which is the distance from the centre of PL to the centre of the clutch arms 6 and 7, is equal to 500 mm (PL/2 + 100 mm); dg, which is the distance from the centre of PL to the outer end of the driver carriage 9, is approximately equal to 805 mm (PL + 5 mm); and d53, which is the distance from the centre of PL to the outer end of the first telescopic guideway 53, is approximately equal to 850 mm (PL + 50 mm).
