OBJECT OF THE INVENTION
[0001] As expressed in the title of the present specification, the present invention refers to a modular system for opening automatic elevator doors, which implies for elevator installers or wholesalers enough capacity so as to place orders under stock instead of by order, to keep a minimum stock, since it is not necessary to store specific parts for opening the door in a certain direction.
[0002] Disposing of a reversible door opening system eliminates numerous references reducing the circulating stock and facilitating manufacturing.
[0003] For the purpose of reducing stock and standardizing manufacturing, the system permits itself to be modular. Many of the parts of the driving part as well as of the driven part can be used, depending on the accessories that are installed therein.
BACKGROUND OF THE INVENTION
[0004] Nowadays it is frequent to find cases wherein mistakes are made in estimating the composition of the stock of these types of parts, especially in the opening direction, depending on whether opening is to the left or to the right, that cause delays and in turn orders with excessively short manufacturing time. These short times cause noteworthy changes in the product manufacturing plan.
DESCRIPTION OF THE INVENTION
[0005] In broad outline, the modular system for opening automatic elevator doors, object of the invention, refers to automatic sliding doors for elevators, wherein the following act:
- The landing door which provides access to the elevator car from the stopping areas of the elevator and which are a driven part.
- The elevator car door that prevents access to the elevator shaft from the car and that upon being motorized acts as a driving part thereof and of the landing door.
[0006] It is a modular type system for opening doors, which means that starting from a common main core the system can become a driving part as well as a driven part, depending on the type of modules that are assembled.
[0007] It consists of a motorized conveying mechanism of the leaves of the elevator car, wherein all the parts that comprise it serve to carry out the opening conveyance to the right as well as to the left, without the need to provide and/or replace any one of them, but rather everything depends on the position and how assembly is done.
[0008] The mechanism for opening the landing door is driven by the conveyance of the leaves of the elevator door. Most of the parts that comprise it, specifically the main module that will be described hereinafter, serve to carry out the conveyance for opening to the right or to the left.
[0009] The main module consists of a system for guiding on a single rail, used for leaves of an elevator car upon being assembled therein, as well as for the leaves of the landing door assembled in the frame of the door.
[0010] The system for conveying between leaves of the very same door is based on a hoisting block, there being some supports for fastening the leaves of the door to the mechanism of the corresponding main module. The guide rail itself can optionally have channels that facilitate the fastening of the peripheral modules.
[0011] Another module that we call the locking module defines a system that is coupled to the main module for the purpose of causing the locking of the leaves and preventing them from opening from outside the elevator shaft when the elevator car is not on that floor level. The locking system is connected to the main module fastened to the frame of the landing door. Connection is made by means of some fastening that define supports for fastening to the rail.
[0012] This locking module has elements that permit the coupling of the driving part in the locking. This driving system is the one that operates the doors of the elevator car, as we will see hereinafter.
[0013] Finally, the motorization module materializes a system that is coupled to the main module for the purpose of carrying out the opening and closing movement of the leaves of the door of the elevator car and in turn it drives and carries out the opening and closing of the leaves of the landing doors on the floor where the elevator car is located. This module consists of a motorization device and a conveying device in order to cause the opening of the landing door.
[0014] In order to provide a better understanding of the characteristics of the invention and forming an integral part of this specification, some sheets of drawings in whose figures the following has been represented in an illustrative and non-characteristic manner, are attached.

In the center part and just as the arrows show, the assembled assembly is seen.
DESCRIPTION OF THE PREFERRED EMBODIMENT
[0016] Making reference to the numbering used in the figures, we can see how the modular system for opening of automatic elevator doors, that the invention proposes, includes a rail (1) whereon the suspension wheels (2) of the leaves of the door slide, as shown in figure 1. The system for conveying said leaves, comprised of the support (3) and the pulleys (4) of the hoisting block device, is also assembled on this rail (1), for movement between the leaves of the very door itself.
[0017] The supports for fastening the leaves of the doors of the elevator car and landing doors are referred to as numbers (5) and (6).
[0018] Figure 2 shows a profile view, the assembly of these parts referred to up to now and that comprise the main module, since all the parts are common, the part for the sliding of the doors of the elevator car as well as the part for the landing doors. Figures 1 and 2 also show the series of longitudinal wings that the rail (1) has, referred to as number (7) and forming C-shaped rails that facilitate assembly of the peripheral modules.
[0019] The locking module is generally referred to as number (8) in figure 3 and the module is shown in a separate detailed view with respect to the main module corresponding to figure 1. And it is also assembled in the corresponding place thereof. Reference (9) designates the supports that materialize the system for fastening to the frame of the landing door.
[0020] The locking module (8) has the purpose of causing the locking of the leaves and of preventing them from opening from the outside of the elevator shaft when the elevator car is not at that floor level.
[0021] Now making special reference to figure 4, the motorization module, generally referred to as number (10) is shown therein and that occupies the top position of this figure. It includes a structure (11) that is coupled to the main module corresponding to figure 1, in order to be able to carry out the opening and closing movement of the leaves of the door of the elevator car. The connection to the elevator car is done by using the structure itself (11) and the leaves of the elevator car connect to the corresponding supports (5) and (6) of the main module, allowing the sliding movement thereof by the rolling support of the wheels (2) on the guide (1) profile.
[0022] The mechanism for opening the landing door is a part driven by the conveying device generally referred to as number (12) and that is assembled on the supports (5) of the main module of the elevator car, allowing the coupling to the locking module (8) and in this way it being possible to convey at the same time the leaves of the landing door.
[0023] With this arrangement of the component parts shown in the figures, where symmetric parts and parts common to the guiding systems of the elevator car doors and the landing doors, act. It is understood that the result of the connection of the main module and the motorization module (8) involves a mechanism that does not need to replace parts, so that it is possible to actuate the doors of the elevator car in the opening direction contrary to the one that is defined at that moment.
[0024] In order for the system for opening doors to be capable of actuating landing doors in the opening direction contrary to the one defined at that time, it is not necessary either to replace any of the parts described in the main module, but rather they only need to be assembled in the place suitable to the desired movement.
