Description:
Telescopic self-supporting gate Field of the invention

The invention concerns a telescopic self-supporting gate, in particular for closing areas, entrances into lands, etc.

Background of the invention

The conventional structure of common one-leaf gates are designed so that a part of the gate is made as a single welded unit which can be controlled either manually or using a motor. These designs are structurally very simple and effective. However, they bring also several disadvantages. The installation space is the main disadvantage as at least the same area as the passage width of the gate is required for when the gate is open. Simply said, if the common conventional design of the self- supporting one-leaf gate is used, it is necessary to have a lateral space available of at least twice the width of the closed gate. It means that this type of self-supporting gate cannot be used in places where space is limited. Also common are two-leaf gates, which open before entering or while entering. A disadvantage of these gates is the necessity to provide free space in the length corresponding to at least one leaf. Other problems can be encountered during the winter period, especially in regions with snow as it is also necessary to clear snow from the area into which the leaves are opened, which is not comfortable, and the driving mechanisms can also freeze in the winter period, which can lead to problems with the gate leaf opening.

Object of the invention

The existing disadvantages of the common designs of one-leaf or two-leaf gates are eliminated by the telescopic self-supporting gate provided by the invention. The invention consists of a gate that comprises of an internal supporting sliding leaf and external floating sliding leaf which move on the same axis while being connected to each other through two "Z" arranged brackets in a movable way. Movements of both the leaves are ensured by means of a steel cable which performs mutual sliding of both leaves with respect to each other through a system of rollers and carriages. As to the design, the internal sliding leaf is mounted through guiding rollers on the first internal carriage and on the second internal carriage. Both the first internal carriage and the second internal carriage are fixed to a solid foundation such as concrete. The two Z shaped brackets are mounted on the internal supporting sliding leaf so that the arm of the first external carriage and the arm of the second external carriage with the guiding rollers, on which the external floating sliding leaf is mounted in a sliding way, are attached to the bottom shorter parts of each of the brackets. Mutually dependent movement of both leaves is carried out by means of a steel cable through rollers which are attached to the front bottom end and rear bottom end of the internal supporting sliding leaf. In order to allow coordinated movement of both leaves, the cable has to be fixed to a bracket mounted on the first internal carriage and it must also be fixed to the bracket which is mounted to the rear bottom end of the external floating sliding leaf.

According to the preferred design, the bracket is mounted to the internal supporting leaf using fastening components, which are led into a connection component through the first grooves created in the central vertical part of the bracket where the mentioned connection component is firmly attached to the internal supporting sliding leaf. The first grooves are also intended for horizontal height adjustment between the internal carrying sliding leaf and the external floating sliding leaf.

Both the connected leaves of the gate have to be adjusted in both the vertical and horizontal directions. The holes through which the set screws for adjustment of the leaves in the vertical direction pass are created on the top shorter part of the bracket for the above mentioned adjustment. Three other grooves through which the adjustment screws pass are created in the bottom shorter part of the bracket for horizontal adjustment of both leaves; the adjustment screws have the primary purpose of ensuring the connection of the external floating sliding leaf with the internal supporting sliding leaf through a bracket. A benefit of the invention consists of the fact that the gate requires a smaller installation space and gate closing or opening takes place at twice the speed of a conventional one-leaf gate.

Description of embodiments

The telescopic self-supporting gate 100 for the closing or opening of the area between the travelling post 26 and the guiding post 28 consists of an internal supporting sliding leaf 1 and an external floating sliding leaf 2 the movements of which are mutually dependent and linked with each other through the "Z" shaped brackets 8, while the mutual displacement of both the leavesI and 2 is carried out by means of a steel cable 19 as described below. Both sliding leaves 1 and 2 are of a frame design and made of steel components in square or rectangular shapes. The movements of both the leaves 1 and 2 during closing or opening of the area between the posts 26 and 28 take place on the same axis. The guiding "C" shaped piece 6 is attached to the bottom part tJ . of the internal sliding leaf ±. The guiding rollers 5 of the first internal carriage 3 and the second internal carriage 4 are housed in the guiding piece 6. Each carriage 3 and 4 contains the base 7 which is mounted to the fixed foundation 72 such as concrete base by means of the screws 7.1

Two vertical stands are mounted to the base 72 the arm on which the guiding rollers 5 are mounted in bearings is installed on a pin in a rotary way between the mentioned stands. The design of the carriages 3 and 4 is described in detail e.g. in CZ utility model No. 2687.

The guiding "C" shaped piece 6 is attached to the bottom part 2J. of the external floating sliding leaf 2. The guiding rollers 5 of the first external carriage 14 and the second external carriage 5 which allow movement of the external floating sliding leaf 2 in the common way are mounted in the guiding piece 6. The guiding rollers 5 of each first external carriage 14 and second external carriage 15 are mounted to the "L" shaped arm 13 (Figs. 4, 5 and 6). The "Z" shaped bracket 8 is attached through its bottom shorter part 8,2 to the arm 13 of each external carriage 14 and 15 using three adjustment screws 12. The "Z" shaped brackets 8 represent the basic component for connection and adjustment of the internal sliding leaf 1 with respect to the floating sliding leaf 2. The bracket 8 is attached to the internal supporting leaf I using the connection component 9 welded to the guiding piece 6 of the internal supporting sliding leaf Threaded holes, which are not illustrated, are created in this connection component 9; the fixation screws, 10 with which the internal supporting sliding leaf 1 is firmly connected with each of the brackets, 8 and thus also with the external floating sliding leaf 2, are led in the above mentioned threaded holes through the vertical grooves 8J3. The vertical grooves 8.3 in the brackets 8 are also intended for height setting and adjustment of the internal supporting sliding leaf 1 with respect to the external floating sliding leaf 2. This height adjustment of the leaf 1 with respect to the leaf 2 is carried out using the set screws 11 which are led through the holes 8J> in the shorter part 8J. of each bracket 8. The horizontal grooves 8,4 through which the adjustment screws 12 are led and with which the bracket 8 is also attached to the arm 13 of the external carriages 14 and 15 as described above are created in the bottom shorter part 82 of each bracket 8 for horizontal adjustment of the internal supporting sliding leaf 1 with respect to the external floating sliding leaf 2. The rollers 18, across which the steel cable 19 is led, are mounted on the front bottom end 16 and the rear bottom end 17 of the internal supporting sliding leaf ±. Feeding of the external floating sliding leaf 2 with respect to the internal carrying sliding leaf 1 is carried out by means of a steel cable 19. In order for this movement of both leaves 1 and 2 to be carried out, the cable 19 is firmly attached to the second bracket 20, which forms a part of the first internal carriage 3. The cable 19 is also firmly attached to the bracket 21 which is mounted to the rear bottom end 22 of the external floating sliding leaf 2. In order that the external floating sliding leaf 2 does not come out of the guiding piece 6, a stop 24 is mounted on the rear bottom end 22 of the external floating sliding leaf 2.

An approach roller, which is not illustrated, which is retracted in the approach pocket 25 mounted on the landing post 26 in the closed position of the gate, 100 is attached to the front bottom end 23 of the external floating sliding leaf 2. The top parts of the sliding leaves 1 and 2 are interconnected with the internal top guiding rollers 27. The external top guiding roller 27.1. which is used to guide the internal supporting sliding leaf 1, is attached to the guiding post 28 from the other side.

When the gate is closing, the internal supporting sliding leaf, 1 the carriages of which 3 and 4 are firmly connected with the base, feeds the external floating sliding leaf 2 by means of the cable 19 through the rollers 18 in a ratio of 1:1; i.e. when the internal supporting sliding leaf 1 is moved e.g. by 1 m, then the external floating sliding leaf 2 is also moved with respect to the internal sliding leaf 1 by 1 m, however, both leaves are moved by 2 m in total.
