The technical field

The invention relates to the gate with the drive according to the restrictive part of paragraph 1 of the claims.

The level of technology

These gates are known from the patent document EP 0890010 B1. Described therein gates has a sliding door leaf spent on top of the side guides that moves between the closed position and open position by means of the system drive. To compensate for the weight of the cloth of the gate is provided by a balancing device that provides stop paintings gate in any position, so that, for example, it is possible to avoid uncontrolled lowering the blade gate in case of failure of the drive system.

Balancing device includes on each side of the sheet gate rope element, passing in the area of corresponding guide, with a spring element to the horizontal section of the guide. Each tether items includes two running parallel cable, which lead to the spring element. Their first free ends are fixed on the canvas gates, second free ends are motionless. While still fastened including through the parts that form the device to align the cable tension in the form of a rocker. Thanks to the device to align the cable tension voltage cables is distributed evenly.

In principle, such tether elements is achieved protection rope break due to the fact that each of the cable elements consists of two separate cables, which, therefore, form a redundant system. If one cable rope element is broken, then the second, more properly functioning cable can perform the function of rope element and thus of the entire counterbalance the device.

However, this has the disadvantage that the existence of a separate cables rope element involves high structural costs. In particular, for the fact that for each cable it is necessary to provide some means of attachment for its free ends.

Disclosure of the invention

An invention is based on objective to present the gates of the mentioned at the beginning of the species for which as you can lower structural costs is provided as large as possible functional reliability.

To solve this problem provides signs point 1 of the claims. The preferred options and suitable variants of improvement of the invention described in dependent claims.

Gates according to the invention, includes a drive system through which the door leaf, held in the side rails, moved between the closed position and open position. In addition, gates include a balancing device rope element and the spring element on one or on each side of the sheet gate, as well as a device to align the cable tension related to element. Device to align the cable tension or all of such devices is protected from a broken cable and rope element or each of the cable elements consists of the rope that goes around situated motionless device to align the cable tension so that we have two branches of the rope passing at a distance from each other. The free ends of the cables are connected and secured to the canvas gate. In the alternative device to align the cable tension could be strengthened on the canvas gate. Then the loose ends of the rope are fixed motionless.

Implementation of the balancing device gate according to the invention, perhaps with small constructive costs. At the same time, this device has a high operational reliability, as it remains healthy and also when you break one of the cable in the cable probe element of the balancing device.

Constructive cost to counterbalance the device is negligible due to the fact that each rope element consists of a single cable. Due to this the number of ends of ropes per rope element that has to strengthen on the canvas gate and on fixed mountings, respectively, significantly reduced compared with cable elements with a few cables.

According to the invention for each rope element is provided by the device to align the cable tension, which ensures the alignment of voltage in both branches of the cable corresponding rope element. The protection in case of a broken cable is provided by the device to align the cable tension. It allows to achieve that, although a rope element consists of only one rope, enveloping its elements, even when you break one branch of the rope remaining branch of the rope is still usable and thus continues to provide the operation of the balancing device.

In particularly preferred embodiment of the invention for it to the device to align the cable tension attached safety device by means of which at break of one branch of the rope is held another branch of the rope.

In a preferred embodiment, the device to align the cable tension is the element in the form of a rod, over which hung a rope, and by which the recorded position of the rope, and especially in preferred case, the element in the form of a rod is a screw.

The element in the form of a rod is introduced in different recess motionless located mounting and fixed them.

Executed thus the device to align the cable tension has an extremely simple design, moreover it is easy and fast service.

Safety device attached to this device to align the cable tension, especially preferred variant has serves as the safety devices still fixed partition with two holes. Through each of the holes is one of the branches of the rope. The following integral part of the relief devices are provided on each of the branches of the rope between the element in the form of a rod and the wall, rigidly connected with a rope thickening with a diameter greater than the diameter of the holes corresponding to this branch of the rope.

If one of the branches of the rope is broken, then the cable can only move until one of the swelling will not come until it is tight up to the bulkhead, and the amount of thickening reliably prevents its passage through the hole in the septum. This ensures hold still working branches of the rope on the safety relief device the device to align the cable tension is why tension still working branches of the rope is saved.

Executed thus the safety device is highly simple design, and it ensures high operational reliability. In particular, preferably partition as a whole-mount the device to align the cable tension due to which the safety device with a device to align the cable tension form a unit.

Application counterbalance the device according to the invention, perhaps with a gate different design variants. The gates can be, in particular, sectional, with lifting or -louvered gates rolled, folding or gates.

Realization of the invention

Figure 1 shows a variant of the implementation of the gate 1, in particular, the gate of the links available on the ceiling, with the canvas 2 gates, the construction of which consists of a large number of panels 3 pivotally connected to each other.

Canvas 2 gate 1 is on his side in the guide rails, which are installed inside the building, in this case inside the garage.

As shown in figure 1, entrance to the garage is closed canvas 2 gate 1. Closed gate 1 canvas 2 gate is in the field of segments guide 4 held vertically. In the open position gate 1 canvas 2 gate is in the field of segments guide 4 held horizontally under the roof of the garage. In a cloth of a gate 2 on both side edges are provided rollers 5, which are held in the guide 4.

For opening and closing of the gate 1 is not shown here-drive system. Drive system includes the carriage being pulled in a known way, motor, which is one of the guides of 4 or separate track. Carriage through not shown rod pivotally connected with the upper edge of the canvas 2 gates. The gate opened or closed by means of movement of the carriage in the field of horizontal segment guide 4.

Gate 1 have a balancing device, the components of which are detailed in fig. 2. Shown on her canvas 2 gate is closed. Figure 2 shows a side view of the guide 4. As can be seen from figure 2, the horizontal part of the guide 4 passes at a distance from the ceiling 6 garages.

As seen in figure 1, on the lower sides of horizontal sections guides 4 placed profile case 7 in the form of tetrahedra, which have built-in components of the balancing device. Figure 2 these components are depicted without profile-case 7.

Cable 10 rope item 8 in the device 12 to align tension changes its direction for the opposite, so it turns out that from this device will come two branches of the cable run parallel on distance from each other, which are conducted through the rollers, 11a, 11b, 11c.

The first guide roller is in the area of ceiling 6 garages. The guide roller is in the field of bending guide 4, which forms the transition between vertical and horizontal segments guide 4.

The second guide roller 11b is at the end of the horizontal segment of the rail 4.

The third guiding roller 11C attached longitudinal end of the spring element 9. Another trailing end of the spring item 9 motionless attached to the sustaining element 13. Spring element 9 consists of a design on the basis of the tension of the spring. Perhaps the passage of separate tightening spring parallel to each other or their location with adhesion to each other.

The free ends of the branches of the cable is firmly connected to each other through a crimp 14. It provides the eyelet 15, which can be formed from the free ends of branches cable or constitute a separate item. Through this eye the 15 free ends of the branches of the cable firmly connected with the bottom edge of the canvas 2 gates.

The principle of action of the balancing device is that the spring element 9 causes an action of the elastic forces of that counteract the weight of the canvas 2 gates so that the canvas 2 gates are held securely fixed in any position on height is guaranteed from falling.

Unit 12 to align tension provides uniform distribution of cable tension between the two branches of the rope.

As can be seen from Phi. 3 and 4, unit 12 to align tension has still mount 16, which essentially consists of metal in the shape of the letter L. Mount 16 has a flat base plate 16a, which mount 16 is fixed on a fixed basis. In the longitudinal direction of the base plate 16A along a straight line at a distance from each other are a few holes 17. In one of these holes 17 injected screw 18, forming element in the form of a rod, and fixed there.

Before the introduction in one of the holes on 17 screw 18 put two washers 19. Between these washers 19 cable is 10 rope item 8, so he goes around the screw 18. Screw 18 19 washers and warp 10 is introduced in different openings 17, depending on the desired degree of tension of the wire. As the cable 10 is located between the washers 19.

As the cable 10 wrapped around the screw 18 so that the alignment of the voltage on both branches of the cable going from the point of changing the direction of the rope. After the rope tightly squeezed by tightening of the screw 18 in this position.

Executed thus the device 12 to align tension is configured in a reversible way, as it is possible at any time, loosen the screw 18 to then re-adjust the tension of the rope in both branches of the rope.

The passage thus the device to align the cable tension attached safety device 12. The first element of the relief devices are provided in the bracket partition 16b, which formed a plot of fastening 16, oriented perpendicular to the base plate 16A. In this partition 16b there are two identical holes 20 of circular cross-section, located at a distance from each other.

Further parts relief device - thickening in the form of a crimp 21, envisaged for each of the branches of the cable 10. Alternatively, thickening may be performed in the form of castings made of metal or form clamping element. As can be seen from figure 3 and 4, crimp 21 are located in those areas of the branches of the rope, which are located between the screw 18 and partition 16b. Diameters pressings 21, performed equally, more holes diameters 20 partitions 16b. The hole diameters 20 are such that the cable 10 passes through them with a slight gap.

With the help of the executed thus the relief device is created effective protection in case of a broken cable in one of the branches of the rope.

If one of the branches of the cable appears to be such a gap of a rope to the tension of a rope in her sharply weakens. However, the cable 10 cannot because of this escape from the devices area of 12 to align tension, as in still working branches of the cable crimping 21 adjacent to the hole 20 and cannot pass through it. The location of the end of working branches of the rope, now become free, pressure-testing of 21, adjacent to the hole 20, a branch of the rope securely held taut, so balancing device will remain functionally intact.

In this case, the partition 16b made in the form of the solid part together with base plate 16A.

In an alternate embodiment partition 16b and base plate 16A can be formed by two separate parts, with each other. Then, instead of the holes is possible presence in the partition 16b longitudinal grooves 20, in which are easily entered the branches of the cable with 21. When the partition 16b is fixed on the base plate 16A, slots partition 16b overlap base plate 16A thus, that part of the grooves, remaining after this open form 20 holes, which are securely held crimp 21.
