Description

The invention relates to a cantilever side sliding gate with a door leaf, which is connected to a drive and has a lower flange in the form of a stiffened hollow box section with a running and support rail held therein for support on support and guide rollers, and the upper flange with a stationary The roller guide works together as a safeguard against lateral tipping

There are various types of side sliding gates of the aforementioned type which are based on roller stands which are held stationary in the ground and which are fixed between two gates anchored on both sides of the gate in the ground with roller guides therein as a safeguard against lateral tipping Well proven in practice and are suitable for gate opening widths of up to 20 m and more. When the door leaf is closed, however, it must be over the width of the door opening protruding section be present, which is supported on the rollers of the fixed roller stands, usually three spaced-apart roller pairs are provided, which cooperate with the running and support rail in such a way that a pair of pull rollers is arranged between two pairs of pressure rollers, through which the door leaf is held clamped in every position. The known designs of the cantilever side sliding gates require a correspondingly large free space on one side of the door opening for accommodating the door leaf in the open position, since this must be accommodated laterally next to the post in its entire length, including its protruding projection in the closed position above the post . When installing these gates in larger enclosure boundaries, the accommodation of the door leaf poses no problems. In many cases, however, a large gate opening width is required in relation to the width of the fenced-in property, without the space required for accommodating the door leaf in the open position being available. In these cases it was previously necessary to use swing gates, which, however, are not only very complex with large door opening widths, but also require correspondingly large open spaces due to their large swivel range, which remain unused and must also be carefully observed when approaching vehicles.

The invention has for its object to provide a cantilever side sliding gate of the type mentioned in such a way that it can be accommodated behind corresponding enclosures or the like.

To solve the above problem, the above-mentioned gate is characterized in that the door leaf is designed as a carrier door leaf for another telescopic and in the open position flat and directly behind the carrier door leaf and in the open position in the opening direction beyond the carrier door leaf, which is at least displaceable Along the box profile of the lower flange of the support door leaf, a cross-sectionally C-shaped support profile part is provided for the engagement of support and guide rollers connected to the second door leaf, and that a roller support acts against lateral tipping on the upper flange of the second door leaf and drives the second door leaf this cable pull, which moves at twice the speed of the carrier door leaf, is connected to the two door leaves.

There are side sliding gates with two telescopically movable door leaves, but these known designs are movable on separate rails embedded in the ground, which are practically effective as individual gates except for the coordination of their drive movements and which due to the required arrangement of the Guideways in the ground lead to considerable disadvantages, which are avoided by the self-supporting design of the side sliding gates. The known design of the side sliding gates with separately movable door leaves on associated rails requires a very considerable amount of construction, in particular with regard to the support and the formation of the corresponding foundations.

The invention is based on the knowledge that door leaves with a lower flange in the form of a stiffened hollow box section have a very high load-bearing capacity, which can be additionally increased by the stiffening of the box section, so that it is possible to design such door leaves as support door leaves and to equip them with corresponding support and guide devices so that the further door leaf is held and guided on the support door leaf can be, in turn it is in turn self-supporting on the support gate leaf. The load on the carrier door leaf is not significantly higher than in an embodiment of the self-supporting side sliding gate in which the carrier gate leaf extends over the entire width of the door opening. Rather, the second door leaf guided on the carrier door leaf, in particular with respect to its upper and lower flange, can be made lighter, so that the total weight of the two door leaves is less than the weight of a single door leaf extending over the entire width of the door opening.

The second door leaf is supported on the carrier door leaf by means of the C-shaped support profile part provided on the lower flange of the carrier door leaf and the rollers of the second door leaf engaging therein in the same way as the guidance of the carrier door leaf on the roller blocks assigned to it in accordance with the embodiment described in the introduction. In other words, in the area of the second door leaf which assumes an overlap position in the closed position with respect to the carrier door leaf, three roller carriers with corresponding rollers can be provided, which engage in the C-shaped support profile part as tension or pressure roller pairs, so that In every position of the door, a secure guidance of the second door leaf is guaranteed, which avoids a tilting movement of this door leaf in the vertical direction with certainty.

In order to prevent a lateral tilting movement of the second door leaf, a support device with corresponding rollers overlapping the upper belt of the second door leaf can be provided on the upper flange of the carrier door leaf at its end facing the door opening, between which the second door leaf is guided with its upper flange.

The arrangement of the C-shaped support profile part along the support door leaf can be done in various ways. A solution which does not adversely affect the stability of the support door leaf is obtained if the cross-sectionally C-shaped support profile part is fastened along the lower flange of the support door leaf on the outside of the lower flange. In this embodiment, the lower flange of the carrier door leaf can be retained in the form known to date with all stiffeners and without any cross-sectional weakening; however, this results in a relatively wide distance between the two door leaves which are guided parallel to one another. As a result, relatively large tilting moments are transmitted to the carrier door leaf, which, however, can be mastered without difficulty by a corresponding design of the upper flange and the support against lateral tilting which cooperate with it.

In a particularly expedient embodiment, in which the upper chord of the carrier door leaf is also designed as a hollow box profile, preferably of a smaller cross-section than the lower chord, the side walls of the upper chord and lower chord facing the second door leaf can have continuous longitudinal slots and C- in the interior of the upper and lower chords. shaped support profile parts can be arranged, through which attached to the second door leaf low-lying arms with attached support and guide rollers and engage with their rollers in the C-shaped support profiles.

In this embodiment, the two door leaves can be guided very close to one another or parallel to one another. However, this results in a weakening of the box profile of the lower flange due to the longitudinal slot necessary in one side wall. Nevertheless, the internal stiffeners, which are usually designed in the form of U-profiles open at the bottom, can be retained in the previous configuration and serve as fastening elements for the C-shaped support profile parts for guiding the second door leaf, so that only a relatively slight weakening of the lower flange of the carrier door leaf, designed as a box profile, has to be accepted. This weakening can in part be compensated for by additional cross bracing in the box-shaped support profile of the lower flange.

The C-shaped support profile part accommodated in the upper chord of the support door leaf forms the roller support against lateral tilting of the second door leaf in this described embodiment, so that any support devices overlapping the second door leaf to prevent lateral tilting can be omitted.

The aforementioned solution represents a particularly elegant design, which also has the great advantage that the C-shaped support profile parts are protected both in the lower part for the transmission of the weight of the second door leaf to the carrier door leaf and for the support of the second door leaf against lateral tipping - or top chord of the carrier door leaf are housed, including the roles interacting with these C-shaped support profile parts. The longitudinal slots in the upper and lower chord of the carrier door leaf can also be protected against the ingress of moisture and dirt by means of elastic apron-shaped slot covers.

In all of the described designs of the self-supporting sliding gate with the telescopically displaceable door leaves, the C-shaped supporting profile parts are expediently rectangular or square in cross-section and, in the case of an arrangement in the upper and lower chord of the carrier door leaf, are held in such a way that their slots are directed towards them the second door leaf.

A particularly visually appealing and, in addition, very stable design results if the second door leaf has a lower and upper flange corresponding to the carrier door leaf, and if a protrusion on the lower flange and / or upper flange of the carrier door leaf extends beyond the lower flange and / or upper flange of the second door leaf Cover plate is provided.

In the case of large door openings and only a small space to the side of this door opening, two sliding gates of the type described, each projecting into the center of the door opening, can be provided, each with a carrier door leaf and a second door leaf of the described design, which can be moved telescopically relative to this.

Show it:

• 1 is a side view of a side sliding gate according to the invention,
• 2 is a plan view of the gate of FIG. 1,
• 3 shows a section along the section line III-III in FIG. 2,
• Fig. 4 is an enlarged compared to Fig. 3 representation of another embodiment of the gate.

1 and 2, the side sliding gate is shown in its closed position. It can be seen that on the right in the figures, to the right of the sliding gate, there is only a small space available for receiving the gate in the open position. In the example shown, the door opening width extends between the stop post 1 and a goal post 2, which is at a smaller distance from the side wall 4 shown on the right in the figures, compared to the door opening. A front cover is provided between the gate post 2 and the side wall 4, behind which the sliding gate shown is accommodated in the open state.

At a distance from said goal post 2, another goal post 5 is provided in the direction of the wall 4. The two goal posts are anchored in the ground in the usual way. The two goal posts 2 and 5 are each designed as parallel double posts which are connected at their upper ends by bridge members 2a and 5a shown in FIG. 2.

The actual gate consists of a carrier gate leaf 6 and another on this carrier gate leaf held and guided second door leaf 7, which extends in the closed position over the support door leaf 6 in the direction of the stop post 1 and is held with its end facing away from this post in an overlap position with the support door leaf 6.

In the example shown, the carrier door leaf is equipped with vertical rungs 9 arranged at a greater distance from one another, while the second door leaf 7 has vertical bars 10 arranged closely next to one another.

The carrier door leaf 6 is connected to a drive, not shown in the drawing, by means of which it can be moved into the closed and open position. Between the support door leaf 6 and the second door leaf 7, a drive connection, not shown in the drawing, is also provided in the form of a cable pull in such a way that when the support door leaf 6 is displaced, the second door leaf 7 is displaced at twice the speed of the support door leaf. Such cables are generally known in the art.

The carrier door leaf 6 has a lower flange 11, which shows the shape of a stiffened hollow box section, as can be seen particularly clearly from FIGS. 3 and 4. In the example shown, the lower flange is stiffened by a U-profile 12 and also serves to receive a running and guide rail 13, which in the example shown is designed as a cross-sectionally T-shaped rail which interacts with support and guide rollers 14, which in turn are firmly anchored in the ground via a foundation plate 15. In Fig. 1, the support and guide rollers 14 with their associated anchorages are only reproduced purely schematically. This figure shows that three pairs of rollers are provided in the example shown, of which the middle pair of rollers can be designed as a pair of pull rollers. The support of self-supporting sliding gates by means of several rollers or pairs of rollers arranged at a distance is generally known, so that it need not be discussed in more detail here.

In the example shown, the carrier door leaf 6 is furthermore provided with an upper flange 16 which is also designed as a box profile. In order to secure the support gate leaf 6 against tilting, in the described bridge parts 2a and 5a of the posts 2 and 5, support rollers (not shown in the drawing) are arranged, which act laterally on the upper flange 16 of the support gate leaf.

A support and guide device for the second door leaf 7 is provided on the lower flange 11 of the carrier door leaf 6 with a cross-sectionally C-shaped support profile part 17 running along the box profile of this lower flange, which in the example of FIGS. 1 to 3 on the second door leaf 7 facing outside of the lower flange 11 of the carrier door leaf is held. Carrying and guide rollers 18 engage in the C-shaped support profile part 17 and are connected to the lower flange 20 of the second carrier door leaf 7 via a support device 19. In this embodiment, the C-shaped support profile part 17 is arranged with its slot facing downward, so that the support device 19 with a corresponding support arm and the support and guide rollers 18 held thereon extends into the interior of the C-shaped support profile part 17.

From Fig. 2 it can be seen that a total of three pairs of support and guide rollers in the execution Example are provided, which are in the closed position of the door in the overlap area of the carrier door leaf 6 and the second door leaf 7. The function of these support and guide rollers 18 is the same as that which has already been described in connection with the support and guide rollers 14 with respect to the carrier door leaf 6.

The weight of the second door leaf 7 is thus deposited on the lower flange 11 of the carrier door leaf 6 via the support and guide rollers 18 and the C-shaped support profile part 17.

In order to prevent the second door leaf 7 from tilting to the side, roller supports 21 in the form of projecting brackets are fastened to the upper flange 16 of the carrier door leaf 6 and in which support rollers 22 which are rotatable about vertical axes and are held on both sides of the upper flange 23 of the second door leaf are held 7 attack. During the movement of the door leaves 6 and 7 from the closed to the open position and vice versa, the brackets 21 with the support door leaf 6 move under the bridge members 2a and 5a of the goal posts. The distance between the respective posts of the two double posts 2 and 5 is dimensioned accordingly large.

In the variant of the embodiment according to FIG. 4, all parts which correspond to the other figures are provided with the same reference symbols.

4, a longitudinal slot 24 is arranged in the lower flange 11 of the carrier door leaf 6 on the side facing the second door leaf 7, and the C-shaped support profile part 17 is arranged in the interior of the lower flange 11 such that its slot aligned with the longitudinal slot 24 in the side wall of the lower flange 11. In the C-shaped support profile part 17, the support and guide rollers 18 are in turn held, which are supported on the support profile part 17 mentioned. The rollers 18 are each carried by cantilever arms 25 attached to the second door leaf 7, which can optionally also be designed as brackets and which extend through the longitudinal slot 24 of the lower flange 11 and also through the longitudinal slot of the C-shaped support profile part 17.

4, a C-shaped support profile part 26 is also arranged in the upper flange 16 of the carrier door leaf 6, in the same way as the C-shaped support profile part 17 in the lower flange 11. Also in the upper flange 16 of the carrier door leaf 6, a longitudinal slot 28 is provided on the side facing the second door leaf 7, through which cantilever arms 27, which are attached to the upper chord 23 of the second door leaf, extend through which free ends 29 rollers 29 which engage in the C-shaped support profile part 26 are held with the C-shaped support profile part 26 cooperate.

In all exemplary embodiments, the C-shaped support profile parts 17 and 26 are designed as rectangular or square profile parts in cross section, so that the walls or flanges adjacent to the longitudinal slots of the profile parts can serve as support surfaces for the rollers provided in the C-shaped support profile parts.

On the lower flange 11 of the carrier door leaf 6 of the arrangement according to FIG. 4, a cover plate 30 is shown in dashed lines immediately above this lower flange 11, which cover plate extends over the Lower flange 20 of the second door leaf 7 extends and covers the gap between the two door leaves, so that this does not appear in the closed position of the door and in both the closed and the open position prevents any foreign objects from above into this gap can fall into it. In the same way, an upper covering of the gap between the upper chords 16 and 23 of the door leaves 6 and 7 could also be provided.
