DESCRIPTION

Door

The invention relates to a door with a door leaf guided in rails that extend laterally and that is transferable from a closed position to an opening position and vice versa by a drive or manually, using at least one closed drive means that It has a load section and a return section, which are composed of various means, the load section having a drag-and-force connection with a drive wheel by means of a chain and the return section, a connection by dragging with a pulley.

Document US 2,672,582 is considered to contain the conventional technique. A drive means is arranged in the space under the roof for the operation of a sectional door, said drive means consisting of two different means, which are a chain and a cable, which are connected in a carriage to form a means. of circulating drive.

From US 3,764,874 an actuating means for a garage door is detached, said actuating means also consisting of a chain and a cable.

Document DE 10 2009 045 796 A1 has disclosed a door with a side drive that is configured as a sectional door to close a building opening. In this case, the door leaf has guides arranged on opposite sides of the building opening to guidely move the door leaf between a position that unlocks the building opening and a position that blocks the building opening, and at the less a section that extends horizontally, as well as a drive to move the door leaf. The drive comprises a transmission device that is connected to the door leaf and is arranged perpendicular to the door leaf, offset, assigned to one of the horizontal sections of one of the guides. In this case, a drive wheel to drive the transmission device, by means of the drive wheel, is configured so that a load section and a return section are available. The axis of rotation of the drive wheel extends vertically and a guide installation is incorporated into the drive wheel, which guides the load section and / or the return section so that the spacing between the sections gradually decreases from the wheel. drive to the building opening.

Document DE 10 2009 044 492 A1 shows a rolling door with a door leaf and guides arranged on both sides. Such roller door has a vertical section and a spiral section, the door leaf being housed, in the open state of the roller door, in the spiral sections forming rolled layers without contact. The rolling door is characterized in that the drive shaft is arranged in the central area of the spiral sections of the guides on both sides and because it extends from one side to the other of the door. In this way a rolling door is provided, whose construction height in the area of the door lintel is intended to be reduced while maintaining a reduced mounting depth compared to the prior art. For the drive, a toothed belt is used, which is carried out as an endless belt that surrounds the door leaf.

From document DE 20 2007 000 460 U1 a roll-up door is known which in the open state is rolled up forming a multi-layer coil. For this, it has a drive unit on one side that carries out the movement of the roller door with a chain that circulates continuously. Similarly, document DE 692 19 654 T2 has a lateral circulating chain for actuating the door.

The object of the invention is to improve the movement of a door leaf of a door having a closed actuating means that is composed of two different means so that a simple assembly of the actuating means is possible and at the same time a noise reduction in the area of the drive means through its structural configuration.

The object of the invention is solved by the features of claim 1. The dependent claims include additional configurations and various possibilities of applying the principle of the object of the invention.

A door that has a door leaf guided in rails that extend laterally and that is transferable from a closed position to an open position and vice versa by a drive or manually, is operated with a circulating drive means arranged at least in one from the sides Such a drive means therefore has a load section and a return section. The portion of the circulating drive means is designated as a load section, which, for example, when opening the door must lift the entire weight of the door. The part of the drive means is designated as the return section which, so that the at least one closed drive means can be completed, closes the circle of the drive means. In such an embodiment, for example, a lateral drive is used to move the door leaf. By such assembly it is possible that, in the case of a mechanical drive, the drive unit can be mounted both laterally and in the center of a through drive shaft. In case of realization with a lateral drive, depending on the size of the

door and its structure, a unilateral or two-sided drive is possible. By using a circulating drive means a simpler drive is made possible. By means of said arrangement, a reduction of the necessary installation space and of the drive parts used is achieved. Therefore, the part of the drive means that is connected to the door leaf is designated as a load section, and the part that is not connected to the door leaf, as a return section. This means that, when the door is opening, the door leaf is lifted by the load section. When, after opening, the door is closing, all the weight is essentially supported again by the load section, which means that the return section is not subject to high loads. The invention is based on this fact to configure respectively the load section and the return section with different means. The load section presents a connection by dragging of form and force with a drive wheel by means of a chain. The return section, on the other hand, has a connection by dragging with a pulley preferably arranged in the lower area of the door leaf.

This implies that the drive means in its load section is formed by links to safely transmit high loads. The return section is preferably formed by a flat material in the form of a flat belt or a V-belt. Such an embodiment implies that the load section is used for the transmission of loads from the door leaf and that the return section only acts as a means of connection between the end and the beginning of the load section. Preferably, the load section and the return section are connected to each other, on the one hand, by a drag and, on the other hand, by a closure. The drag is designed so that it can also have, for example, rollers that are guided in a lateral profile. Simultaneously, this drag has a connection to the lower part of the door leaf, preferably, by means of a ball joint.

To reduce noise during opening and closing as much as possible, the drive means is preferably guided within a guide profile and for the reduction of structural noise an insulating coating is arranged within the same guideline profile.

For a drive means of such characteristics with its chain links to remain continuously engaged with the drive wheel, according to the invention, a tensioning device for automatically tensioning the drive means has been conceived within the closed drive means. Such tensioning device is automatically adjusted within a certain range. In the case of reaching the limits of this margin, a sensor element is also available to detect this situation. At the same time, this element can also be used as an indicator of the possibility that the drive unit should be replaced.

Such tensioning device is designed according to the invention as a replaceable unit and is essentially composed of a mounting unit having a base plate with angled lateral elements. A two-part arm is rotatably mounted on the base plate, which by means of a guide element can make a certain predetermined path in a guide groove. By means of these characteristics, together with the sensor element, a safety device is provided that allows a connected door of this type to always be prepared to operate in any circumstance. The guided arm in the guide groove is loaded by means of a spring element so that a deflection wheel that is arranged on one side of the arm remains continuously pressed against the load section of the actuating means.

Such a door provided with a drive means of the aforementioned type can be configured as a lifting door or as a sectional door or as a rolling door or as a rapid opening door or the like.

Other advantages, features and possible applications of the present invention result from the following description, in combination with the embodiments shown in the drawings.

Figure 8, a lower connection to the door leaf;

Figure 9, like Figure 8, but in an individualized perspective view;

Figure 10, like Figure 9, but from a different angle; and Figure 11, as Figure 10.

Figure 1 shows a drag -1- that is part of a closed drive unit -2-. Also shown are a load section -58-, at the top of the drag -1-, and a return section -6-, below the drag -1-. The load section -58- is articulated jointly on one side to the drag by an appropriate connection -3- and the return section -6- is also connected to the drag-1- by means of a fixing -8-. The other ends of the return section -6- and the load section -58- are connected to each other by means of a closure -7-.

Within the conveyor -1- rollers -4- are mounted, which allow to ensure a clean guidance of the conveyor -1- within a guide profile -10-. In addition, the conveyor -1- has a door leaf connection -5-, preferably in the form of a ball joint -54-. In the representation of figure 2, this configuration of the drive means -2- with two different materials can be clearly observed. The load section -58- forms a connection by force drag and form with the drive wheel -19- (not shown here) and the return section -6- is guided only by means of a pulley -13- represented in figure 4 and which is smaller in diameter than the drive wheel -19-. Such flat belt may preferably be plastic, provided with a corresponding fabric, or the like. However, it is also possible to use a leather strap or the like.

Within the guide profile -10-, the drive means -2- is guided so that no accidental contact from outside can take place. In order to properly isolate the noise, a liner -9- preferably made of a plastic or the like is placed inside the guide profile -10-. The lining -9- is connected to the guide profile -10- preferably at certain points, in order to avoid a direct transmission of the operating noise to the resonant structure of the door frames or the like. Through an overhang -11- the inner area of the guide profile -10- is practically divided, so that, even with a rapid movement of the door leaf, the elements of the load section -58- that move in directions Opposites cannot come into contact.

Within the guide profile -10- there is a continuous groove -60- through which a part of the conveyor -1- stands out and at the same time the connection to the load section -58- and the return section -6 is established -. The part that goes out through the slot outwards is connected to the door leaf by means of a connecting lever -39-.

In the individualized representation of figure 4, on the one hand, the pulley -13- can be observed for the return section -6-, which is supported within the guide profile -10- by means of a threaded shaft -12-. In addition, the figure clearly shows that the lining -9- is placed inside the guide profile -10- against an inner wall thereof.

So that the return section -6- is properly guided by means of the pulley -13-, it has bearings -14- that provide a smooth operation. This is achieved by means of the threaded shaft -12- inside a bearing support -15-. The end of the threaded shaft -12- is screwed into the threaded hole -16- with a thread. The threaded shaft head -12- is arranged inside the groove -60-, of which, in the section, only one side is shown. To obtain a clean guide of the return section -6-, which is not shown in this view, guide collars -61- are arranged laterally on the pulley -13-, so that the return section -6- cannot involuntarily getting out of the pulley -13-.

Figure 6 shows an upper part of the door with the drive unit -17- and the drive means -2-. The drive means -2- in the form of a load section -58- is driven by means of a wheel -19-. For reasons of clarity, only part of the cargo section -58- has been drawn. In the area where the unloaded part of the load section -58- is not shown, a tensioning device -20- is provided for tensioning the drive means -2- as a whole. The tensioning device -20- is adjustable in position by means of adjustment -24-. By means of a diverting wheel -21-, the drive means -2- remains continuously under tension. By means of the drive unit -17-, which is not further developed, in this case the wheel -19- and a drive shaft -18- are driven. The turning movement of the wheel -19- is transmitted via the drive shaft -18- and a coupling member in between, for example, from the right to the left side of the door leaf. Therefore, even in the case of larger doors or sectional doors, it is not only possible to make a unilateral elevation but also on both sides of the door leaf from the closing position to the opening position and vice versa.

In the individualized representation according to figure 7 the tension device -20- is shown in detail and clearly. Starting from a base plate -63- angled elements -62- of a piece folded by stamping are observed laterally. Within the piece folded by stamping, a guide groove -23- is arranged, in which a guide element -28- of an arm -27-, -32- of two parts is engaged. The arm -27- is supported at a turning point -29- such that the deflection wheel -21- is rotatably mounted at the end of the longer arm -27- by means of a shaft -26-. As the second part of the arm, the cam -32-, which extends from the pivot point towards the other end, acts together with a switching element -30- in the form of a switching spring -31- to detect the appropriate tension in the drive means -2-. A spring element -25- acts on the arm -27- so that the spring element -25- always maintains adequate pressure on the actuating means -2-. By means of the adjustment means -24- the general adjustment of the tensioning device -20- can be influenced as a whole. To have a sufficient adjustment, a slot -22- is arranged in the drive module according to figure 6.

As the upper part of the drive unit has already been exposed with the load section -58- of the drive unit -2- in the above description, we now proceed to expose the bottom part and therefore the connection to, for example , a panel -35- of a door or the like. The lower termination of the panels -35- is formed by a joint -37-. With respect to the representation according to Figure 8 it should be noted that it is the realization of the right side of a door or the like and that, therefore, the same construction is also found on the left side. By means of a stop plate -36-, a fixing device -59- has been fixed to the panels -35-. On one side of the stop plate -36- there is a rail -33- to provide mobility to the panels -35- by means of rollers that are not shown. In a space between the panels -35- and the rail -33- a photoelectric barrier element -34- is arranged.

In order to clarify the detailed construction of the fixing device -59-, reference is made to an exploded view of Figure 9.

For connection of the conveyor -1- by means of the door leaf connection -5- the connection lever -39- is provided. While through a hole -41- the door leaf connection -5- is connected with drag-1-, at the other end of the connection lever -39- there is a turning point -40- preferably made by way of of a ball joint -54-, which carries out the connection to the transmission lever -44- by means of the ball joint connection -54-. The transmission lever -44- is connected and secured within a hole -55- with a rotation shaft -42- arranged in an angled element -47- of the stop plate -36-. By means of the connection through the hole -55- a two-arm lever is also formed for the transmission lever -44-, the connection lever -39- being fixed at one of its ends and can be calibrated at the other of its ends the connection with the drag -1-. The possibility of calibration is obtained by means of a bushing -46- guided in a guide groove -45- with a threaded hole -57-. The bushing -46- has lateral surfaces -53- that interact with the stop plate -36- within an opening -52-, so that the bushing -46- is inserted into a hole -56- of a sliding piece - 48- variable and tightened by means of a connecting screw -51- against a guide -49-. The sliding part -48- is variable in its height by means of an adjustment screw -50-. This changes the position of the transmission lever -44- simultaneously. Due to the possibility of adjusting by means of the adjusting screw -50-, the actuation point for the connection lever -39- can be adjusted continuously with the drag -1- and its corresponding connection to the door leaf -5- .

In the transmission lever -44- there is also a guide groove -43- that is aligned with a hole -64- inside the guide -49-. A shaft of a roller, not shown, is inserted in the hole -64-. The roller serves to guide the door leaf into the lateral rail -33-.

Figures 10 and 11 clearly show the adjustment device -38- again to adjust the connection lever -39-. The sliding piece -48- is supported inside the guide -49-.
