Detailed description of preferred embodiments of the invention

Figures 1 and 3 shows the side views of the existing roll-up doors, equipped with standard systems of balance and tension. As can be seen from figure 1, above the door is installed with the possibility of rotation of the upper roller 1 and the cable drum 7, which is equipped with a drive (not shown), when this door curtain 2 (door leaf) made with the possibility of winding while working around the roller 1 and unwinding with him. To the lower end of the curtain 2 attached to the lower beam 3, to which is attached one end of a cable 6, the other end of which is attached to the drum 7. The cable 6 passes around a stationary pulley 4 and a movable pulley 12, podpruzhinennom deflecting the spring 5, working in tension. Spring 5 can also be installed above the door opening, as can be seen from the Phi is .3. In any case, the spring 5 is stretched when the impact load on the curtain 2, for example under the action of wind or other external forces. In the standard door systems shown in figures 1 and 3, the stretching or elongation of the spring 5 is limited only by the internal spring. Unfortunately, strong winds or other external loads on curtain 2 this fact can lead to undesired lifting of the beam 3.

The tensioning system and trim doors used in the present invention successfully solves the problems described above, and thus is devoid of the disadvantages inherent in existing door systems. It is obvious that within the scope of the present invention, the cable 6 may be a wire, a belt, a chain, cord, rope, etc. as a replacement roller 1 can also be used, inter alia, the disks that are located on each side of the doorway frame with established therein by the rollers of the required size, or other means known to the specialists.

As can be seen from figure 2, in one embodiment of the invention using curtain 2 made with the possibility of winding on the roller 1, is placed over the doorway and provided with a drive (not shown). To the edge of the curtain attached 2 beam 3. Also use the cable 6, one end of which is attached to the beam 3, the other to the drum 7. The cable 6 passes around the pulleys 4 and the pulley 12, podpruzhinennom spring 5. When the load on the curtain 2 spring 5 is stretched.

Because the elongation of the spring in the standard system, tension is not limited by the present invention, as can be seen from figure 2, a fixed restrictor lengthening or a mechanical stop ("hard stop") 9A and 9B, which does not allow the spring 5 to move at some point. The advantage of this focus is that it does not beam 3 to rise up when exposed to a strong wind or other external loads on curtain 2. Stop 9 may be, for example, the first element 9A, which is under tension of the spring cooperates with the second element 9B attached to the pulley 12. Mechanical end stops 9, described in this patent is resisted not only wind, but also the increased load caused by the operation of air conditioners, fans, etc. and the vertical load exerted on the curtain 2, for example, in case of unauthorized entry. In addition, when the door is closed you can use the mounting beam 3, for example mechanical or Electromechanical locks.

Limiting the elongation of the spring 5 creates tension between the beam 3 and the roller 1. This, in turn, gives the beam 3 to climb up pravoslavie wind or other external loads, because the fixed roller 1 its movement is limited by the cable 6. To prevent rotation of the roller 1, you can use the brake actuator or, in extreme cases, additional locking device. In this regard, it should be noted that the elongation of the rope 6 under load can lead to a decrease in the efficiency of the device, therefore, when choosing a cable 6 should take into account the need to minimize undesired elongation. In addition, it is obvious that the springs 5 and 13 can actually be a combination of two or more springs (e.g., the spring 5 on Fig)that can be placed in various locations, for example at the top or bottom of the door opening or inside of the upper roller. In addition, the springs 5 and 13 can be placed on one or both sides of the door and connected in parallel or sequentially. It is also apparent that the springs 5 and 13 may be made of rubber bands connected in parallel or formed into loops. Similarly the role of the springs 5 and 13 in each of the embodiments of the present invention may be suitable pneumatic or gas springs and hydraulic springs.

Obviously, curtain 2 may contain fabric with a protective coating, plastic film, flexible or rigid plates or slats, etc. materials, the possession is the following possibility of rolling into a roll. In addition, the door curtain can be able to bend in all directions, and only in the direction of rolling, essentially, not being able bend in other directions by attaching to the curtain 2 stiffeners or other appropriate means. In addition, the door may not be vertical and horizontal, i.e. when working to move in the lateral direction, or can even be installed at an angle. When this beam 3 is not a required design element and if it is not the cable or cables 6 can be attached to the bottom edges of the curtains 2.

As described above, the present invention has certain advantages over analogues in terms of protection against rising curtains 2 when exposed to a strong wind or other loads. For example, in one existing door system provided increased tension in the open position due to the action system tension/balance that, however, is undesirable because it introduces instability in the operation of the mechanical door systems. The disadvantages of the known locking systems are their complexity and high cost. Door system in accordance with the present invention, in contrast, has a number of advantages, including high reliability, low cost and, in particular, flexibility, ensure the sustained protection from impact.

Previous attempts to provide trouble-free operation of the door is equipped with a powerful closing tensioning system, revealed a number of problems. For example, the door system Pozidriv" limits to ensure trouble-free operation due to the requirements of the rigid mounting beam 3 to the drive.

The design of the present invention, in contrast, provides increased closing tension only when the closed position of the door. This means that in the intermediate positions of the door beam 3 feels less tension on the drive side. (This spring 5 or 13 always provide some tension curtain 2). Accordingly, the use in the present invention shockproof system is simplified with a more flexible connection beams 3 to the drive.

One variant of the device, ensuring trouble-free operation, provides for releasing door curtains from the guide channels through which the curtains move when raising and lowering, when exposed to large external force, e.g. due to a vehicle collision or other moving object. Shockproof device not raskrepljajut the door when exposed to strong wind loads or, for example, hacking. It should be noted that the best way shockproof system trigger when the door is titsa in half-open" state (in which the majority of collisions), and, as a rule, are less effective when the door is completely closed. Shockproof device may include a variety of mechanical or Electromechanical device, such as a finger, breaking upon reaching a certain threshold onlile, the sensor connected to raskrepljajut device, or spring-loaded device. If necessary, shockproof device may be included in any of the following in this patent of the embodiments of the invention.

Figure 4-6 shows other variants of the present invention. For example, figure 4 shows a variant of the invention, in which the working tension spring 5 is placed at the top and not the bottom part of the door opening. Figure 5 and 6 show other options involving the use of instead of the spring 5, as shown in figure 1, operating on a compression spring 13. The spring 13 may be down (figure 5) or up (Fig.6). In both of these cases, at full compression it itself acts as a hard stop. Moreover, an advantage of all variants of the invention, shown in Fig.4-6, is that the elongation or compression of the springs 5 or 13 does not give the beam 3 to rise under the influence of external loads on curtain 2. Compression springs shown in these figures may also be connected in series or in parallel.

7-12 shows other options from which retene, involving the use of an additional pulley 8 ("step-down pulley) and a composite cable 6. Here, each of figa, 8A, 9A, 10A, 11A and 12A is a small change, respectively, 7, 8, etc. in which the diameter of the drum 7 is inferior to the diameter of the roller 1. The advantage of using a composite cable 6 is to reduce lowering of efforts and reducing the diameter of the cable drum, which leads to space saving and cost reduction. For example, a variant of the invention, shown in Fig.7, curtain contains 2 with beam 3 and is wound on the roller 1. The first part of the cable 6 with one end attached to the drum 7, and then passes through the pulley 12, podpruzhinennom spring 5, and further pulley 4 and the other end of the rope attached to the speed-reduction pulley 8. The second part of the cable 6 with one end attached to the beam 3, then passes through the pulley 4 and the pulley 8 and the other end of this cable is attached near the lower part of the doorway. As shown in Fig.9, the spring 5 can also be placed in the upper part of the doorway.

In addition, in the present invention may also be included limiter 9 elongation, as seen from Fig and 10. Instead, as shown at 11 and 12, can be used the spring 13 with built-in stops. Thus, in addition to the advantage of a reduction of the gathering force and diameter of the drum, variants of the invention shown in Fig and 10-12, in which the elongation or compression of the springs 5 or 13 is limited, have the additional advantage, expressed in the restriction of movement of curtains 2 when working with high loads. As can be seen from Fig, 17 and 20, the stopper 9 can be equipped with a mechanism 10 of the fixing and unfixing, for example an electromagnet, which can be triggered by a sensor or other suitable means. Each of the options shown in figure 2, 4, 8, and 10, limiting the elongation of the spring 5 does not allow lifting beams 3 under the influence of external loads on curtain 2. In other variants mentioned in this patent, are used for this purpose similar mechanisms to lock and unlock. While the examples given here are for illustrative purpose and do not limit the essence of the present invention, since it is obvious that it is possible to use other mechanisms for fixing and unfixing.

For professionals it is obvious that in the construction of the present invention can be incorporated in various combinations of springs or deflecting means in combination with means providing trouble-free operation and safety. For example, on Fig shown the door, which is designed to work under stress and the construction of which is similar to the one shown in figure 2, in which the OTF is nichael lengthening replaced by the segment 11 of the circuit, rope, wire, etc. that restrict the movement of the spring 5. As device protection circuit 11 can be used in combination with the mechanism of "weakest link" (not shown) to protect the components of the door when the strike or other emergency involving exposure to excessive load.

On Fig shows another variant of doors, working under stress and is depicted in figure 2, which includes a second spring 5 and a mechanical stop 9A and 9B elongation. Thus, the two springs arranged in series, and both resist displacement of the door, while the stopper 9A and 9B prevents the movement of the springs 5 and ultimately curtains 2 at some point.

On Fig shown the door, which is designed to work under stress and the construction of which is almost identical doors shown on Fig. The main difference is that on Fig second spring 5 is replaced by the load 16, which operates in cooperation with the spring 5 and does not let up curtains 2. It is obvious that the weight of this load can be optimized in accordance with the particular operating conditions.

On Fig depicts another version of the door operating under high load, in accordance with the present invention, which combines the mechanism 10 shown in Fig, use the th together with double spring 5 and the stopper 9A and 9B, shown in Fig. In this embodiment the movement of the two springs 5 is limited by the stopper 9A and 9B to the occurrence of the events leading to the securing mechanism 10, which raskrasit part 9A of the limiter and allows the force applied to the curtain 2, the influence of the spring 5.

On Fig shows another variant implementation of the present invention, involving the use of working on the compression spring 13 and spring 5. The spring 13 operates in cooperation with the mechanical stop 9A and 9B and restricts the movement of the curtain 2. As the spring 13 and spring 5 slows down or prevents the movement of curtains 2 within its course. On Fig depicts a system almost identical to that shown in Fig, except that Fig the spring 13 is replaced by a pneumatic or gas spring 15. As can be seen from Fig, the spring 15 can contain at least one pressure valve 14, which may contribute to the limitation of the stroke of the curtain 2. Replacement air spring hydraulic lets get similarly functioning system, which used valves.

Another variant of the present invention, shown in Fig, involves the use of a spring 13 in combination with the stopper 9A and the mechanism 10.

Another option Nast is asego of the invention shown in Fig, which shows the door system 100 containing lowering and stretching system. The door system includes working for balancing compression spring 101, working in tension lowering spring 102, connecting the pulley 103, the roller 104 of the door leaf, the cable drum 105 in the form of a truncated cone, the first wire 107 and the second cable 108. If necessary, the system can also include a spring stopper 106, limiting the stretching of the spring 102.

In one preferred embodiment of the invention the diameter of the drum 105 is equal to half the diameter (D/2) roller 104, the roller 104 and the drum 105 rotates with the same speed and in the same direction. When opening and closing the door, the effective diameter of the drum 105, i.e. the portion affected by the cable 107 at a certain point in time, declining at a rate similar to that which varies with the thickness of the roller 104. In other words, when lowering the door curtains 110, the thickness of the roller 104 is reduced. While the drum 105 receives the cable 107, which is wound on an increasingly small part of the diameter of the drum 105. This leads to the fact that the action of opening or closing of the pulley 103 is held a distance approximately equal to only half of the curtain 110. In addition, due to the efficient balancing of the system drum 105 p the dinner 102 does not move or barely moves at relatively constant pressure, we at curtain 110 and the drum 105, respectively cables 107 and 108.

The limiter 106 limits the elongation of the spring 102. The actuator (not shown) and a cable 108 lowering the curtain 110 and hold it stretched is tensioned than that which can provide only one spring 102. Therefore, the door can be closed even when exposed to strong wind. In this case, the limiter 106 must have a minimum clearance to prevent jamming of the cables and their excessive stretching.

In some cases it is desirable to use the cable drum in the shape of a truncated cone (105), the diameter of which exceeds half the diameter of the roller 104. This configuration provides for the restriction of movement of the spring 102 limiter 106 in the closed position of the curtain 110. In this position the lower door beam will be less vulnerable in a collision, for example, with the vehicle as it and the door curtain can exit the side rails. This allows for easily use in such a door system known automated branch curtains and automatic return to the operating position. In addition, the effects of the limiter 106 against the spring 102, the actuator lowers the curtain down 110 using the first and second cables.

Other versions of this configuration is tion may include the use of additional pulleys to limit the stroke of the pulley 103, that, in turn, allows to increase the diameter of the drum 105. Additional pulleys also limit the elongation of the spring 101.

The configuration shown in Fig, allows you to operate the door with the necessary force lowering and tension, i.e. gives an opportunity to optimize the size of the springs for specific operating conditions. The advantage of this system is that it is possible to use only one cable drum on each side of the door for effective support and door trim. In addition, since the system is essentially balanced, you can reduce the size of the spring 102, and, essentially, to keep moving it to zero. In addition, the use of the limiter 106 and prevent the displacement of the actuator in the opposite direction in those cases when it is not used, leads to a reliable fixing of the door, which increases the degree of protection. And finally, this configuration uses the torque generated by the actuator, as for lifting door curtains, and its sinking during opening or closing, which makes it suitable for operation at very high wind loads.

Another variant of the present invention shown in Fig. Although the drum 105 and the roller 104 here, for clarity, shown in the form of two separate wheels, in practice they fo is s on the same axis. The roller 104 is placed curtain 110, which is attached to the cable 108. The cable 108 is connected to the drum 105 through a combination of three pulleys 116. At least one of these three pulleys attached to the spring 102. Spring 102 optionally may be attached to the stop plate 106, which may, if desired, be adjustable gap. The cable 108 is attached to the cable 107 coupler 115. The cable 107 extends at least one pulley 118, and in the preferred embodiment, three combined the pulleys and connected with a spring 101.

The door system 111 shown in Fig, stretching system is separated from the balancing system. Balancing of the system 111 passes from the clutch 115 to the spring 101, and stretching system - from curtains 110 to the clutch 115. The diameter of the roller 104 depends on the thickness of the curtain 110 and varies depending on the position of the door from a maximum when the door is fully open to the minimum when fully closed the door.

When rolling curtains 110 in a roll or lowering the drum 105 due to its shape of a truncated cone causes the change of the diameter of the roller 104, providing the balancing forces applied to the curtain 110. As the roller 104 and the drum 105 are located on the same axis, they rotate at the same speed. Due to its shape of a truncated cone drum 105 determines ISM the imposition of the rotational speed and torque, attached to it and the roller 104 when lifting the curtain 110 or lowering. A slight discrepancy in size of the drum 105 and the roller 104 is compensated by the spring 102. In addition, at least one variant of the invention provides for the use of the drum 105 with a larger step than the step ratio roller 104.

Spring 102 creates a tensile force F1, which can be optimized for specific operating conditions. Spring 102 resists stretching curtains 110 under high wind loads and prevents the displacement of the curtain 110 in the vertical direction under such loads. The limiter 106 can be used to prevent excessive stretching of the spring 102, and prevent displacement curtains 110 when exposed to extreme loads, when not enough of spring 102. The gap between the stopper 106 and the spring 102 can be optimized so that the spring is effectively operated during the operation of the door, providing a constant value of force F1. In addition, the adjustable gap can be configured so that when the door is closed its value is zero, thus preventing the displacement of the curtain 110. In some embodiments of the invention increase the resistance curtains 110 high loads is achieved by the use of the lower beam 120.

The force F1 does not affect the equilibrium of the system. When you open the curtains 110 or closed, the diameter of the roller 104 and the drum 105 remains approximately the same. Thus, the torque caused by the force F1 on the drum 105, will be almost identical to the torque caused by the force F4 on the roller 104, but with the opposite sign, leading to an almost equilibrium state of the system. Any imbalance is compensated by the spring 101.

The force F3 on the drum 105 is approximately equal to the force F4 on the roller 104. When the system is in equilibrium, the force F2 transmitted by the spring 102 is approximately equal to the force created by the half mass curtains beams 110 and 120. Increasing when moving down the curtains 110 force F4 is compensated by the growth of opposing efforts F2 transmitted counterbalancing spring. Therefore, the system remains balanced during the entire operation as when moving up and down.
