Description

DESCRIPTION

ELEVATOR DOOR SYSTEM THE RELATED ART

The invention relates to an elevator door system which is used in multi-storey structures and in all kinds of buildings, and which saves energy by shortening the opening distance of the elevator.

The invention particularly relates to an elevator door system used in elevators, which enables rails to be collapsed and opened within the door mechanism by reducing the distance of moving rails by maintaining the floor and cabin entrance distance, and which saves energy by driving a spoon system by means of a spoon system motion mechanism.

THE PRIOR ART

Transportation systems are one of the most popular and fastest developing and competitive sectors nowadays. The construction of multi-storey buildings for people's needs, comfort and natural environmental conditions has also increased the research and development works of companies operating in elevator systems.

Nowadays, elevators are used in homes and offices etc. indoor places. These elevators have automatic floor doors and interior safety cabin doors. The operating systems and the low strength of these structures cause continuous failure and safety breaches.

In the prior art elevator systems; three different kinds of floor doors as automatic right hand side collapsing telescopic, left hand side collapsing telescopic, and central opening system, and an interior safety door are found. The automatic floor doors function by manual movement and since the elevator shaft side walls stay close to the door edge concrete and side wall concrete areas during mounting due to the sizes and dimensions of the mechanism, it causes friction and narrow space. This reduces the quality of system operation and creates a safety flaw.

The fixed rail dimension disclosed in the above said mechanism is a measure of the total length of the cabin entrance space distance and the collapsing distance of the door with regard to the opening direction. This length not only causes additional material costs but also causes loss of energy due to more movement during operation. In the prior art, during mounting of the floor doors, even though attention is given to balance plummet dimensions, retraction of the right, left, front, rear, and diagonal plummets during bolting and welding fixation, and not recognizing this situation during dimensional checks, causes the storey door fixing mounting operation to be repeated. This causes mounting difficulty, loss of human power and waste of labour.

The improper installation of the automatic doors in the elevator systems used in the prior art leads to mounting difficulties and prevents the elevator systems from operating efficiently due to not being 100% plummet. In the prior art, the size of the mechanism fixed rail being close to the shaft side walls causes friction at the door edge concrete. This causes a safety flaw.

In the prior art, the fact that there is no fixed balance indicator on the door causes the measurement to be lost from the plummet. As a result, when the door opening movement at the cabin floor is transferred to the manually moving floor door by the spoon system, the automatic doors cannot operate in the same harmony with the interior safety door and the aesthetic appearance is distorted. Due to this, efficient operation does not take place. In the prior art, the length of the fixed rail dimension of the mechanism leads to material waste within the mechanism frame and the floor door frame. This increases material costs.

In the prior art cabin interior safety automatic doors; it is necessary to set more than one dimensions when the door centering operation is performed during the connection of the internal safety automatic door mechanism legs to the automatic door locking slides on the cabin. This requires long human power and time. In the prior art, the interior safety automatic door fixing on the cabin, the automatic door model used while fixing on the L-type or vertical triangle leg models on the cabin top slides, fits 1/1 if it is procured from the manufacturer. If another model of cabin is purchased from another cabin manufacturer, the fixing leg does not fit the cabin top slides, and mounting difficulty is encountered. Cost burden is encountered when the cabin and the automatic door are purchased from the same manufacturer company.

In the prior art, during the door panel suspension operation after completion of the mounting operations, the panels are suspended depending on the cabin entrance distance, and it is not possible to adjust the height of the panel easily in accordance with the height of the panel when the interior safety automatic door is left above or below. When on the panels, said adjustment and fixing settings are checked again to reposition the interior safety automatic door mechanism to the panel length. This process leads to loss of human power and loss of time.

In the prior art, all the problems encountered in automatic floor door are also encountered since the floor door opening direction is directly proportional with the interior safety automatic opening direction. In order to eliminate this situation, the breaking operation of the side walls of the well called trimming is performed, or the opening direction of the internal safety automatic door is pulled to the end point in the opposite direction. In this case, adjustment of the door becomes difficult and efficient operation is restricted.

In the prior art, the interior safety automatic door on the cabin inside the automatic safety door is stretched depending on the traffic intensity during the operation period of the automatic door stabilization foot slides. When tilting to the right or left side occurs, friction occurs with the interior safety automatic door panels or narrowing occurs with the floor automatic door operating distance. This causes material damage.

When the prior art internal safety automatic door cabin is mounted over the cap, the size of the door mechanism protrudes to a large extent on the cabin, which causes the cabin suspension area to narrow down. This situation restricts the intervention of the elevator maintenance personnel due to the limited space of the elevator. The elevator maintenance personnel who cannot use this area has to control the elevator system manually by moving to the other part of the rear suspension of the cabin. As a result of this, the human body goes out of the cabin over the rear guardrail, and the head, arm, or body of the personnel may hit the counterweight in the elevator systems as result of carelessness, which causes injuries or even death.

In the prior art, the cabin top maintenance personnel needs to adjust the automatic floor door from the front side on the cabin. However, the large size of the internal safety door mechanism causes difficulties for the maintenance personnel.

In the prior art, when the counterweight application is made near the cabin, iron profiles of different geometry are applied to fix the counterweight rails. When this area applied is close to the interior safety automatic door mechanism fixed rail or the mechanism frame metal sheet, problems are encountered in some applications depending on the shaft size and this leads to elevator accidents and damages due to friction, getting caught etc.

In order to prevent the above said problems, the internal safety automatic door and automatic floor door options are utilized. For maintaining the cabin entrance, the width of the panel is narrowed down and the numbers are increased in order to reduce the size of the fixed mechanism rail or mechanism metal sheet in the direction of collapsing and opening. Increasing the number of panels in the automatic door system is a factor that increases the cost burden. As a result, a need has occurred for an economical and useful elevator automatic door for solving the above said prior art problems and bringing an improvement to the relevant technical field due to the inadequacy of the prior art solutions.

PURPOSE OF THE INVENTION

The invention solves all the problems given above at the same time. The most important purpose of the invention is to give inwards and outwards movement capability to the rails found on the door mechanisms. Another purpose of the invention is to reduce the motor movement of the cabin entrance distance by 50% with regard o the prior art systems with a 1 /2 system, and still maintain the door opening distance. Another purpose of the invention is to reduce energy consumption by providing a 100% increase in engine life with the restriction of 50% movement of the door motor.

Another purpose of the invention is to provide ease of assembly and be easily adjustable. In this way, the purpose is to reduce the required manpower and loss of time.

Another important purpose of the invention is to provide the rails found on the mechanism system with 1 /2 motion capability, and allow the automatic door opening direction to be met by the moving rails found within the own mechanism thereof, and thus keep the shaft side walls away from the movable mechanism and ensure easy mounting and practical adjustment opportunity.

Another purpose of the invention is to provide mounting advantage in the plummet by means of the fixed balance indicator of the automatic door mechanism.

Another purpose of the invention is to eliminate the friction at the shaft side wall in accordance with the opening direction of the automatic door by means of the movable mechanism rail. Another purpose of the invention is to provide cost advantage without the need for using an additional mechanism metal sheet, since it is mounted in the automatic door frame.

Another purpose of the invention is to provide a cost advantage by shortening the moving rails in the mechanism by ½ working technique.

Purpose of the invention is to prevent the motor providing the movement of the ½ motion mechanism rails from narrowing down the cabin entrance space in accordance with the opening direction against the 50% motion restriction. Another purpose of the invention is to eliminate the need for the prior art cabin cap (frontal) piece and to provide cost advantage in cabin production by mounting its own mechanism metal sheet at this area.

Another purpose of the invention is to be compatible with all types and models of domestic and imported product cabins.

Another purpose of the invention is to eliminate the need for the mechanism fixing L and right triangle leg attachment apparatuses.

Another purpose of the invention is to prevent the need for cabin top automatic door fixing metal sheet slides for the cabin manufacturer companies. In this way, cabin manufacturers will ensure cost advantage by not producing cabin top slides. Another purpose of the invention is that since the cabinet is mounted on the cap (frontal) section with its own mechanism metal sheet, the internal safety automatic door centering allows for the possibility to work in the center without having to center and adjust since there are individual cabin entries. Another purpose of the invention to collapse the mechanism moving rails within its own mechanism metal sheet when the ½ movable mechanism rails close the elevator system door and start moving. In this way, when the elevator system is in motion, the situations of friction with the shaft side wall, deformation, and hitting are eliminated and accidents are avoided.

Another purpose of the invention is that the cabin can be mounted on the cap (frontal) area so that the right, left and front side bending comes to 0% position and thus prevents possible damages and accidents by maintaining the working distance between the floor automatic door system and the elevator system while the elevator system is in motion.

Another purpose of the invention is to provide mounting on the cabin cap (frontal) area, and therefore it does not protrude upwards on the cabin so that the elevator maintenance personnel can use this area and easily access the cabin top auxiliary panel of the elevator system and prevent the risk for the personnel to encounter the balance counterweight and thus increase the safety of the maintenance personnel.

Another purpose of the invention is to provide a lower cost advantage compared to other systems since the cabin has the same size with the cap frontal region.

Another purpose of the invention is to prevent the friction, getting caught, collision and elevator accidents which may occur in this area by means of the internal safety automatic door mechanism moving rail by means of the internal safety automatic door opening mechanism and the internal safety automatic door opening direction of the counterbalance weight.

Another purpose of the invention is to ensure that elevator system, when reaching the called floor, uses all the space up to the shaft side walls while the automatic door is opened and thus eliminate the need for using wide mechanism and system with increased number of panels with regard to the dimensions and sizes of the shaft.

In the light of said purposes, the invention is an elevator door system used in elevators, eliminating the problems encountered in the prior art embodiments, providing energy saving with a system change by maintaining the floor and cabin entrance distance, and thus facilitating maintenance and repair services, and it comprises a rail system shortening the opening distance, carrying the door panels thereon and thus providing motion to the door panels, and allowing the movable rails to be collapsed and opened within the door mechanism by shortening thereof, and a spoon system motion mechanism transmitting the motion coming from the motor to the spoon system. The rail system has the same width with the elevator door entrance distance and thus the prior art necessity of having a difference in size is eliminated. The spoon system motion mechanism comprises stabilizer pulleys providing balance and strength to the system when the elevator door system is opened, by making pressure on the support force equalizer from below and above, a first pulley used for increasing the movement distance of the support force equalizer, a second pulley found on the spoon system motion mechanism (6) and transferring the incoming movement to the spoon system, a distance lever found on the spoon system motion mechanism and restricting the movement distance, and a motion pin allowing the up-and-down movement of the system to be on a single line.

The spoon system motion mechanism (6) consists of the main components of a stabilizer pulley (6.1 ), a first pulley (6.2), a second pulley (6.3), a distance lever (6.4), and a motion pin (6.5).

In Figure-1 , Figure-2, Figure-3, and Figure-4, the system is shown from different angles and in closed and open states. The invention comprises a rail system (1 ) shortening the opening distance of the system, carrying the door panels thereon and thus providing motion to the door panels, and allowing the movable rails to be collapsed and opened within the door mechanism by shortening thereof, a movable panel hanger plate (2) used in adjusting the door panel up and down during the suspension operation and providing motion in the opening-closing direction, a guide rail carrier system (3) used for guiding the rail system (1 ) when the body is fixed, a support force equalizer (4) used for counterweight balancing during complete opening and complete closing of the door panel with the movement of the rail system (1 ), a motor motion system (5), the operation area of which is restricted by 50% motion restriction, and allowing 100% opening of the panels, a spoon system motion mechanism (6) moving the spoon (12) system after the interior safety door panels are closed and providing harmonious operation with the floor door, a balance plummet indicator (7) positioned on the floor door frame and interior safety automatic door and showing the plummet values of the fixed mounted door mechanisms, a mechanism frame (8) carrying the system and performing the tasks of frame and cabin in addition to cap, a motion transmitter (9) transmitting motion between the pulley guide rail, a panel connection 1 /1 hanger plate (10) mounted on the movable rail for carrying the panel in a movable manner and providing connection to the rear first panel with 1 /1 ratio, a safety plug contact (1 1 ) used for safety in the system, and a spoon (12) system transferring the motion to the panels.

The most important novelty in the invention is the elements of the rail system (1 ) and the spoon system movement mechanism (6).

As another element, the spoon system motion mechanism (6) is the element that gives movement to the spoon (12) system. In this way, the movement of the spoon system takes place not by a belt which is connected to the motor but by the spoon system motion mechanism (6). This shortens both the operating distance and ensures energy saving.
