Description

The invention relates to a sliding gate device comprising a sliding gate element mounted so that it can be displaced horizontally via at least one lower guide and at least one upper guide, the upper guide being held on at least one first support element and the lower guide being attached to a base and/or to the first support element and/or or is held on at least one second support element. The invention also includes a sliding gate linear guide.

Sliding gate devices or sliding gate linear guides of the generic type are used in particular to close driveways or access roads to properties. In principle, however, they can also be used to close pedestrian passages, machine housings or to move sliding doors, sliding walls, sliding windows or the like. Sliding gate devices of this type are well known in the prior art and are available in large numbers on the market. However, what is common to such sliding gate devices is that guides for guiding the heavy sliding gate element are implemented as roller guides. The high weight of the sliding gate element is usually supported on rollers of the lower guide. The upper guide prevents the sliding gate element from tilting, with the sliding gate element generally being supported longitudinally on at least one roller and preferably between two or more rollers. The rollers are rotatable and are often held in the guides by roller bearings. However, such roller bearings for the rollers are expensive, complex to assemble and often require intensive maintenance. Moisture can penetrate the roller bearings due to weather influences and cause them to corrode, which leads to a reduced service life and often makes it necessary to replace the roller bearings. This can be remedied by regular maintenance of the roller bearings by protecting them from the effects of the weather with lubricants and/or seals. There is also the risk that dirt particles, such as grains of sand or the like, will cling to the rollers over time and penetrate their roller bearings, for example. This also leads to premature wear of the rolling bearing or requires the use of suitable rolling bearing seals. Rollers soiled in this way also cause the problem that the rollers leave behind a layer of dirt, grinding marks or scratches when the sliding gate element is moved, for example due to abrasion, particularly on the upper guide. In the case of metallic materials which are coated with an outer, generally thin anti-corrosion layer, such scratches can destroy this anti-corrosion layer locally, so that there is an increased risk of corrosion for the underlying base material from these points. Furthermore, such signs of abrasion of the rollers affect the aesthetics of the sliding gate element and there is a risk of getting dirty on contact with them. The rollers are often kept freely accessible, especially on the upper guide, which means that there is also a risk of crushing injuries.

If particularly high demands are placed on the smooth running or the accuracy of the guides of the sliding gate element, this is held on both longitudinal sides between rollers of the upper guide. The upper guide is preferably supported on two support elements, so that its rollers are held on it with the lowest possible bending moments. This results in a high level of stability of the upper guide, although support elements are required on both longitudinal sides of the sliding gate element and, as a rule, foundations on which these can be supported. The assembly effort and the production costs of such sliding gate devices are therefore comparatively high.

The object of the present invention is to further develop a sliding gate device or a sliding gate linear guide for a sliding gate device in such a way that they can be produced more cost-effectively with the same guiding accuracy, are easier to assemble, are safe to operate and require reduced maintenance.

The invention has the features of claim 1 in order to achieve the object. Accordingly, the upper guide of the sliding gate device comprises at least one first sliding body which is elongated over a rail length and is held on the sliding gate element and at least one second sliding body which is held on the support element and has a contact length which is less than the rail length of the first sliding body, the sliding bodies preferably corresponding to one another have shaped and/or form-fitting sliding surfaces and wherein the first sliding body is provided with the first sliding surface so that it can be displaced horizontally along the second sliding surface of the second sliding body.

The particular advantage of the invention results from the shape of the upper guide with sliding bodies that can be slid horizontally on one another. Compared to ball or roller bearing or roller guides, this upper guide based on sliding bodies has a significantly lower surface pressure. Consequently, in the Sliding surfaces of the sliding body a large-area load distribution, which is suitable to absorb high forces emanating from heavy, large sliding gate elements. This upper guide with sliding bodies is comparatively insensitive to coarse dirt and sand. When the sliding gate element itself moves, these dirt particles are pushed away from the sliding surfaces of the sliding bodies. As a result, the upper guide means there is a significantly lower risk of damage from abrasion marks or scratches on the sliding gate element. As a result, the upper guide is more durable or maintenance-free than roller guides and does not pose a risk of injury from open pinch points.

The first sliding body and at least sections of the sliding gate element are preferably profile-shaped. A suitable profile shape for the sliding gate element - at least in sections - has hollow chamber profiles, also called construction or assembly profiles. These hollow chamber profiles can be produced inexpensively, for example using the extrusion process, and have a sufficiently high strength with a low weight.

According to a preferred embodiment of the invention, the first sliding body is held on an upper chord of the sliding gate element, which preferably extends longitudinally at least over the length of the rail of the first sliding body.

According to a further development of the invention, the upper chord has a profile groove which extends longitudinally over the length of the rail and in which the first sliding body is held in a form-fitting manner, at least in sections. For example, the upper chord provides an elongated profile with a C-shaped cross section and a longitudinal recess into which the first sliding body can be pushed and held in a form-fitting manner.

According to a development of the invention, the upper chord has a closed cross-section or the first sliding body is held on the upper chord by a material connection or via at least one first connecting means. The upper chord can be produced particularly cost-effectively as a box-shaped hollow chamber profile with a closed cross section. The first sliding body of the upper guide is preferably mounted on the upper chord with little effort using suitable first connecting means, for example screws. Alternatively, the first sliding body can also be welded to the upper chord.

According to an alternative embodiment of the invention, an intermediate connection profile is provided between the upper chord and the first sliding body. In any case, the intermediate connection profile extends longitudinally over the length of the rail and is held on the upper chord via the at least one first connection means or in a materially bonded manner.

According to a further development of the invention, the intermediate connection profile has a locking recess which is shaped in a manner corresponding to the first sliding body, for accommodating the first sliding body at least in sections. The first sliding body and the intermediate connection profile have snap-in connection means which can be brought into engagement with one another. In this respect, the first sliding body is held in a non-positive or positive manner on the intermediate connecting profile via snap-in connections formed from the snap-in connection means brought into engagement with one another. The first sliding body preferably provides an essentially plate-shaped section which has latching lugs on the top and bottom. The locking recess of the intermediate connection profile is essentially C-shaped and shaped correspondingly to the plate-shaped section of the first sliding body. It provides latching hooks located opposite one another on the top and bottom, which can be brought into engagement with the latching lugs, forming an undercut. The first sliding body can preferably be inserted into the intermediate connection profile by pressing in the latching lugs between the latching hooks.

According to a development of the invention, the first sliding body is an integral part of the upper chord in such a way that an elongated recess with a circular cross section and a longitudinal gap is formed. The first sliding body in the upper chord is functionally formed by the longitudinally stretched recess, which is circular in cross section, and the longitudinal gap that is formed in this way. The upper chord with the first sliding body is formed in one piece and is preferably realized as a profile, in particular as a metallic extruded profile.

According to a development of the invention, the first sliding body has a ring-segment-shaped cross section with a longitudinal gap, the second sliding surface being formed by its inner lateral surfaces. The second sliding surface is therefore free of edges and is therefore in principle well suited for accommodating the second sliding body.

According to a development of the invention, the second sliding body has a circular cross section, with its outer surface forming the second sliding surface. The second sliding surface is free of edges and is therefore in principle well suited for being pushed into the first sliding body.

According to a further development of the invention, in an assembly position, the first sliding body encompasses the second sliding body on the casing side. This Arrangement means that the sliding surfaces are encased by the annular segment-shaped first sliding body and thus protected. As a result of this arrangement, less moisture or fewer dirt particles reach the sliding surfaces, which could possibly lead to premature wear of the upper guide formed from the sliding bodies. Since the sliding surfaces are free of edges and shaped to correspond to one another, this assembly position can be carried out easily without the risk of tilting. The second sliding body can be pushed into the first sliding body without the risk of tilting and is held in it in a form-fitting manner.

According to a development of the invention, the second sliding body has a holder groove, at least one and preferably two or more and particularly preferably exactly two holders being held in the holder groove for connecting the second sliding body to the first support element. The holders and the holder groove of the second sliding body are preferably shaped to correspond to one another, so that an undercut is formed after the holders have been pushed into the holder groove of the second sliding body. This makes it very easy to mount the holders with the second sliding body.

According to a development of the invention, the holders for connecting the second sliding body to the first support element are guided through the longitudinal gap in the first sliding body. The longitudinal gap is preferably greater than or equal to a wall thickness of the holder, so that the second sliding body can be rotated in the first sliding body with slight play. This minimizes the risk of the holder tilting with the first base body and any inaccuracies, for example caused by the lower guide when the sliding gate element is moved and/or the impact and vibration movements that occur as a result, can be absorbed or compensated for without the good running properties of the upper guide to affect. In principle, guiding the holder through the longitudinal gap of the first sliding body makes it possible to move the first sliding body horizontally along the significantly shorter second sliding body without corresponding to the holder.

According to a further development of the invention, the second sliding body is held on the face side between exactly two holders. This prevents the second sliding body from being moved when the sliding gate element is moved horizontally and, for example, from moving horizontally from its holder groove to the holders.

According to a development of the invention, the first sliding body is held on a longitudinal side of the sliding gate element, with the longitudinal gap pointing downwards. With this arrangement, the sliding surfaces are well protected from weather conditions. Precipitation flows off the first sliding body without reaching the sliding surfaces. Good friction properties of the upper guide of the sliding gate element formed by the sliding body are thus retained even in the event of precipitation.

According to a development of the invention, the holders are connected to the first support element via an intermediate connecting piece. The intermediate connector makes it possible to manufacture holders with a very simple geometry at low cost. In addition, the intermediate connecting piece enables a connection of the second sliding body of contact length B, which is held between the holders at the front, to a significantly wider first support element.

According to a development of the invention, the holders are connected to the first support element and/or to the second sliding body and/or to the intermediate connecting piece via at least one second connecting means and preferably via a screw connection as the second connecting means. On the one hand, this results in advantages of a detachable screw connection, on the other hand, it is conceivable that the holders are held via screw connections equivalent to a rotary joint and form a first axis of rotation with the second sliding body and a second axis of rotation with the intermediate connecting piece and/or the first support element. This articulated arrangement is able to compensate for inaccuracies in the guides, in particular the lower guide of the sliding gate element.

According to a development of the invention, the lower guide is formed by longitudinally profiled, telescopically extendable pull-out elements, with a first pull-out element on the bottom flange of the sliding gate element and a second pull-out element, which engages with the first pull-out element, on the ground or on the first support element or on at least one other Supporting element is held. This embodiment of the lower guide is particularly advantageous when a short stroke is required, preferably in the range of 40 cm to 1.5 m, and the sliding gate element of the sliding gate device is designed as a sliding door, a sliding window, a sliding wall or the like. In this respect, the lower guide is formed similarly to a drawer extension with extension rails, the extension elements engaging in one another in a manner similar to the extension rails of the drawer extension so that they can be displaced relative to one another. Guide means, for example slide bearings or roller bearings, are preferably provided between the pull-out elements.

According to an alternative embodiment of the invention, the lower guide is a roller guide with at least one and preferably four or more rollers. Such roller guides have proven themselves to absorb the heavy weight of sliding gate elements several meters wide and to guide the sliding gate element at the same time.

While retaining the inventive idea, it is fundamentally conceivable for the rollers of the lower guide to roll directly on the ground or on at least one rail or plate placed on the ground.

According to a development of the invention, the lower guide of the sliding gate element has a plurality of two or more roller blocks on which the rollers are rotatably mounted and held at a height to the ground, the roller blocks being supported on the ground by an equal number of base plates. This prevents the rollers from rolling directly on the ground, which would cause increased soiling of the rollers. Dirt particles, such as grains of sand and the like, could easily get stuck on the rollers and leave scratches or grinding marks on the surface of the sliding gate element when it is moved. Because the rollers are held on the roller blocks, the risk of such contamination is significantly reduced.

It is conceivable that the roller blocks have a swivel joint for adjusting an inclination of the rollers to the ground. In this case, slight unevenness or inclines in the subsoil can be leveled out without much effort. The base plates are preferably designed in such a way that they have a sufficiently large support surface to support the high weight forces of the sliding gate element. In addition, they preferably have bores or recesses, so that they can be connected directly to the subsoil or preferably to a foundation in the subsoil via other connecting means, for example ground anchors or screw connections.

According to a further development of the invention, the sliding gate element is guided along the rollers on the underside via a longitudinally profiled running rail. A hollow chamber profile, for example, offers a suitable running rail geometry, which can be produced inexpensively and has a sufficiently high strength with a low weight. An example is an extruded aluminum profile. In principle, it is conceivable that the running rail is held on the longitudinal side of the sliding gate element, for example when the lower guide is held on support elements.

According to a development of the invention, the roller blocks are guided through a longitudinal slot in the running rail, which preferably faces the ground. This arrangement represents a preferred arrangement and enables the sliding gate device according to the invention to be installed on a substrate in a cost-effective manner.

According to a further development of the invention, inner walls of the running rail enclose the running rollers in such a way that a jacket-shaped running surface of the running rollers preferably rests against the inner walls of the running rail and this is widened on the longitudinal side in such a way that end faces of the running rollers preferably do not touch the inner walls of the running rail. The rollers are well protected from dirt and weather influences by the surrounding rail. As a result, less wear and less maintenance of the lower guide can be realized. Since the running rollers are only in contact with the running rail with their running surface, there is minimal friction when the sliding gate element is moved. The running rail is widened on the longitudinal side, for example by means of a V-shape on the longitudinal side, so that no unnecessary friction occurs between the end faces of the running rollers and the inner walls of the running rail when the sliding gate element is moved.

According to a further development of the invention, the first support element is a support post which preferably protrudes from the ground and is positioned next to the longitudinal side of the sliding gate element which holds the first sliding body. The support post preferably has a square cross-section. However, while retaining the inventive idea, it can also have a circular or another shaped cross section.

In principle, it is also conceivable that the first support element, for example a building wall or a wall post or in the case of a sliding gate device according to the invention with several sliding gate elements that can be slid next to one another, is an adjacent sliding gate element.

According to a development of the invention, a first material of the first sliding surface of the first sliding body is harder than a second material of the second sliding surface of the second sliding body. This combination of materials is selected in such a way that wear occurs primarily on the second sliding body, which is cheaper and easier to replace. In the event that such a wear-related replacement of the second sliding body is necessary, the repair costs caused thereby can be kept as low as possible.

According to a development of the invention, the second sliding body is self-lubricating the second material and preferably made of plastic and/or ceramic and/or graphite in such a way that the first sliding body can be displaced along the second sliding body, preferably permanently and without auxiliary lubricants. This self-lubrication by the second sliding body can be brought about by different principles. The second material of the second sliding body can, for example, have an amorphous basic structure with solid lubricants embedded therein, such as graphite and/or brass. Another possibility is that microscopically small amounts of the second material of the second sliding surface are transferred to the first sliding surface of the first sliding body and fill out or smooth out unevenness there, whereby the sliding gate device according to the invention can be moved along the upper guide permanently and maintenance-free without auxiliary lubricants.

• - the intermediate connector is retained on the first support member.

According to a further development of the invention, in the position of use the first sliding body is held in a profile groove of a profile-shaped, for example C-shaped and longitudinally stretched upper chord of the sliding gate element. The first sliding body can be pushed into the profile groove of the sliding gate element at the front, for example, and is held therein in a form-fitting and/or force-fitting manner. This results in a cost-effective and simple installation for the position of use of the sliding gate linear guide according to the invention on the sliding gate element.

According to an alternative embodiment of the invention, the first sliding body is held in the position of use on an upper chord of the sliding gate element in a materially bonded manner or via at least one first connecting means or via an intermediate connecting profile extending longitudinally over the length of the rail.

According to a further development of the invention, the intermediate connection profile has a latching recess which is shaped in a manner corresponding to the first sliding body, for at least partially accommodating the first sliding body in the position of use. The first sliding body and the intermediate connection profile have snap-in connection means which can be brought into engagement with one another. The latching connection means are preferably formed from latching hooks and latching lugs which can be brought into engagement with one another and which are provided on the top and bottom of the latching recess of the intermediate connection profile and a correspondingly shaped section of the first sliding body.

According to a development of the invention, the first sliding body is preferably connected to the upper flange of the sliding gate element via the at least one first connecting means and particularly preferably via a screw as the first connecting means in the position of use. The top chord can be implemented here, for example, as an elongated hollow chamber profile that is closed in cross section and can therefore be produced particularly cost-effectively.

According to a development of the invention, the first sliding body transitions in one piece into the upper chord of the sliding gate element in such a way that an elongated recess with a circular cross section and a longitudinal gap is formed. The first sliding body is functionally formed by the elongated recess, which is circular in cross-section and has the longitudinal gap. As a result, assembly of the first sliding body can be saved on the sliding gate element.

A first embodiment of a sliding gate device according to the invention, which is used to close pedestrian passages, driveways or driveways for land, is in 1 until 6 shown. The sliding gate device comprises a cantilevered sliding gate element 1 which is mounted on a lower guide 2 and on an upper guide 3 so that it can be displaced horizontally.

The sliding gate element 1 after 1 is elongated and usually has a length of 40 cm to several meters, so that in an open position of the sliding gate device according to the invention, for example, people can walk through or motor vehicles can drive through. Such elongate sliding gate elements 1 are usually made of a metallic material such as aluminum or stainless steel and are accordingly often very heavy. The lower guide 3 of the sliding gate element 1 is fixed to the lower flange 24 on the underside and largely absorbs the weight of the sliding gate element 1 . In order to absorb loads acting as a result of tilting moments of the sliding gate element 1 and to relieve the lower guide 2 , an upper guide 3 is additionally provided on the longitudinal side of the sliding gate element 1 . The upper guide 3 is preferably provided above a center of gravity of the height of the sliding gate element 1 for an advantageous load distribution. In the illustrated exemplary embodiment of the sliding gate device according to the invention, the upper guide 3 is provided in a particularly preferred position on an upper flange 23 of the sliding gate element 1 and is supported on a first support element 19 .

The sliding gate device according to the invention is in 1 shown in perspective and with a sliding gate element 1 that is open at the front and shown in sections in a longitudinal direction. This representation of the sliding gate element 1, which is open at the front, primarily serves to describe it. In practice, the sliding gate element 1 is preferably closed or covered at the front. In the exemplary embodiment shown, the sliding gate element 1 has a fence-like shape. In this case, between a horizontally elongated and hollow-profiled upper chord 23 and a similarly shaped lower chord 24 of the sliding gates Elements 1 held a plurality of vertical and parallel cross members which are spaced equally from each other. In addition, a convexly curved, hollow chamber-shaped cover profile 25 is placed on top of the upper flange 23 .

The upper chord 23 of the sliding gate element 1 has a profiled groove 20 on the longitudinal side, in which the upper guide 3 is held in a form-fitting manner. The lower guide 2 is provided on the underside on the lower chord 24 of the sliding gate element 1 . It has an elongate and hollow-profile running rail 17 with a longitudinal slot 22, within which a plurality of running rollers 18 are guided. The running rail 17 is in the sliding gate device after 1 manufactured in one piece with the bottom chord 24 of the sliding gate element 1 . The longitudinal slot 22 of the running rail 17 faces the ground. Two roller blocks 15 are guided through the longitudinal slot 22, which act as fixed bearings for the rollers 18 arranged in pairs and keep them rotatably mounted at a height relative to the ground. The roller blocks 15 prevent the rollers 18 from rolling directly on the ground and dirt particles from the ground from adhering to the rollers 18 . This increases the service life or maintenance-free running rollers 18 and ensures consistent running properties.

The upper guide 3 is in the embodiment according to 1 held on exactly one longitudinal side 21 of the upper chord 23 of the sliding gate element 1 on a first support element 19 . This first support element 19 has the shape of a square support post and, for aesthetic reasons, ends horizontally at almost the same height as the top flange 23 of the sliding gate element 1 . One of the roller blocks 15 and the first support element 19 are supported on a common base plate 16 on the ground. The second roller block 15 is supported on a base plate 16 of smaller surface area on the ground. Both the roller blocks 15 and the first support element 19 have lower connection or flange sections for connection to the base plates 16 or to the ground. Bores and/or recesses are preferably provided in these connecting or flange sections and in the base plates 16, so that the roller blocks 15 and the first support element 19 can be connected to the base plates 16, preferably via bolts or screws or similar connecting means. For a sufficiently secure hold, the base plates 16 and/or the roller blocks 15 and the first support element 19 should preferably be set up on foundations.

The detail Y off 1 is in 2 and shows enlarged the upper guide 3 held between the upper flange 23 of the sliding gate panel 1 and the first support member 19. The upper guide 3 of the sliding gate panel 1 is connected to the first support member 19 via brackets 10 and an intermediate connector 11. The support element 19 is bent in a substantially C-shape and has two end sections 13 which protrude from the first support element 19 at right angles in the direction of the sliding gate element 1 . The intermediate connector 11 is held between two holders 10 via second connecting means 14.2. Suitable second connecting means 14.2 are screw connections, for example—as shown. The holders 10 are guided through a longitudinal gap 6 of a first sliding body 4 of the upper guide 3 so that an end section and a second sliding body 7 held between the holders 10 are covered by the first sliding body 4 .

The upper guide 3 is based on the sliding bodies 4, 7. In 3 the correspondingly shaped and interlocking sliding bodies 4, 7 of the upper guide are shown in a side view without the second connecting means 14.2. The upper guide 3 is shown with a holder 10 held in a form-fitting manner in a holder groove 9 of the second sliding body 7 and the first sliding body 4 held in the profile groove 20 of the upper chord 23 of the sliding gate element 1 . The first sliding body 4 has a ring-segment-shaped cross section with a longitudinal gap 6 . Its inner lateral surface forms a first sliding surface 5. The second sliding body 7 is shaped to correspond to the first sliding surface 5 of the first sliding body 4 and is held in the first sliding body 4 in a form-fitting manner. The second sliding body 7 has a circular cross section, with its lateral surface forming the second sliding surface 8 . The sliding bodies 4, 7 are consequently connected to one another in a form-fitting manner in such a way that their sliding surfaces 5, 8 lie against one another. During a horizontal movement of the sliding gate element 1, the first sliding surface 5 slides along the second sliding surface 8. The material of the sliding bodies 4, 7 or their sliding surfaces 5, 8 is preferably selected so that they have the lowest possible coefficient of friction or, when moving the sliding gate element 1, the lowest possible produce low friction. The cover profile 25 is placed on the upper chord 23 . It projects beyond the upper chord 23 on the longitudinal side, so that rain is drained off via the first sliding body 3 and a connection point between the first sliding body 4 and the profile groove 20 of the upper chord 23 is protected.

The holder 10 has a nose-shaped section which is held in a form-fitting manner in the holder groove 9 of the second sliding body 7 and is shaped to correspond to the holder groove 9 . The holder 10 is guided through the longitudinal gap 6 of the first sliding body 4 . The first sliding body 4 is held on the sliding gate element 1 in such a way that its longitudinal gap 6 points downwards or in the direction of the ground. This has the advantage that the sliding surfaces 5, 8 remain free of moisture in the event of precipitation, which could have a negative effect on their running properties. Furthermore, this arrangement of the longitudinal gap 6 also protects the sliding surfaces 5, 8 as far as possible from dirt particles adhering. The holder 10 is preferably bent in a V or L or concavely in such a way that an intermediate connecting piece 11 fastened to it is held at the same height as the sliding bodies 4,7.

4 shows a rear view of the sliding gate device according to the invention 1 and provides an insight into the sliding gate element 1, which is open at the front. Rather, the running rollers 18 run along their running surfaces on horizontal inner walls of the running rail 17. As a result, the resulting friction on the running rollers 18 and the running rail 17 is reduced to a necessary minimum. The rollers 18 are arranged in pairs at the same axial height and are held on the roller block 15 at a height relative to the ground. The roller block 15 is guided through the longitudinal slot 22 of the running rail 17 . It is formed from two sections bent in an L-shape and positioned mirror-inverted to one another, between which a support section with roller axles for the rollers 18 is screwed and/or riveted and/or pivoted.

5 shows the detail Z from 4 . In it, the upper guide 3 is shown enlarged. The holders 10 are each connected to the end sections 13 of the intermediate connecting piece 11 and to the second sliding body 7 via the second connecting means 14.2. Suitable second connecting means 14.2 are, for example, screw connections such that the holder 10 is held in a pivotable manner. This makes it possible to compensate for slight misalignments or manufacturing tolerances of the guides 2, 3.

6 shows the upper guide 3 of the sliding gate device according to the invention 1 in a detailed eruption. The C-shaped intermediate connecting piece 11 is held between the holders 10 via the second connecting means 14.2. The intermediate connector 11 has a connecting portion 12 which is intended to be connected to the first support member 19 but is shown free and not connected to the first support member 19 in this illustration. The end sections 13 of the intermediate connecting piece 11 protrude perpendicularly from the connecting section 12 and are connected on the outside to the holders 10 via the second connecting means 14.2. A screw connection consisting of a screw and a nut is used as the second connection means 14.2. In order to connect the intermediate connection piece 11 to the first support element 19, the connection section 12 has three bores in this exemplary embodiment, so that the intermediate connection piece 11 can be connected to the first support element 19 via screw connection means. The second sliding body 7 with a contact length B is held between the holders 10 in the first sliding surface 5 of the first sliding body 4 . The contact length B of the second sliding body 7 is preferably significantly smaller than the rail length S of the first sliding body 4.

one in the 7 until 9 Illustrated, second embodiment of the sliding gate device according to the invention provides that the upper chord 23 of the sliding gate element 1 and the first sliding body 4 of the upper guide 3 are in one piece. Accordingly, the upper chord 23 of the sliding gate element 1 is designed as an elongated, four-edged hollow chamber profile with a recess provided on the longitudinal side 21, with a circular segment shape in cross-section and stretched longitudinally over the rail length S, which forms the longitudinal gap 6 on the longitudinal side 21. The first sliding body 4 is functionally formed by the recess with the longitudinal gap 6 . The recess forms a structure which projects inwards from the longitudinal gap 6 and is enclosed in the form of a ring segment, in which the second sliding body 7 is held in a horizontally longitudinally displaceable manner.

The upper guide 3 and the profile cross-section of the upper chord 23 of the sliding gate element 1 of a third embodiment of the sliding gate device according to the invention are shown 10 in a detailed view open at the front. The upper chord 23 here has a square hollow chamber profile with a closed cross section, which has an advantageous high mechanical stability and can be manufactured cost-effectively.

The cover profile 25 placed on the upper side is not reproduced here. On the longitudinal side 21, an intermediate connection profile 26 extending longitudinally over the rail length S is fixed to the upper chord 23 by means of helical first connection means 14.1. The intermediate connection profile 26 has a substantially C-shaped locking recess, which top and is surrounded on the underside by latching hooks 28.1, 28.2.

The first sliding body 4 has a section corresponding to the latching recess of the intermediate connecting profile 26 with two latching lugs 27.1, 27.2 located opposite one another on the top and bottom, so that it can be inserted into the latching recess between the latching hooks 28.1, 28.2. As a result, the screws with which the intermediate connection profile 26 is fixed to the upper chord 23 are advantageously covered by the first sliding body 4 . In order to create the necessary bending flexibility for latching the latching lugs 27.1, 27.2 between the latching hooks 28.1, 28.2, a latching lug recess 30 running parallel to the latching lug 27.2 is provided on the first sliding body 4 in the area of the underside latching lug 27.2. In addition, a handle section 29 that can be gripped protrudes vertically downwards from the latching lug 27.2 on the underside. In addition to the latching connections, the first sliding body 4 is connected to the intermediate connecting profile 26 on the underside by means of screws that are partially concealed by the first sliding body 4 and are not visible from above as the first connecting means 14.1.

The first sliding surface 5 and the longitudinal gap 6 are formed in the first sliding body 4 as usual. The second sliding body 7 is held in the first sliding surface 5 as usual.

A detailed view of the upper guide 3 and the profile cross-section of the upper flange 23 of a fourth exemplary embodiment of the sliding gate device according to the invention is open at the front 11 at. The upper chord 23 has a four-edged closed hollow chamber profile, which can be produced inexpensively and has a high mechanical stability. The cover profile 25 is not reproduced. The first sliding body 4 is fixed here directly on the longitudinal side 21 to the upper chord 23 via the helical first connecting means 14.1. Otherwise, the first sliding guide 3 and the sliding bodies 4, 7 are designed as usual.

A second material of the second sliding body 7 is preferably softer than a first material of the first sliding body 4. As a result of the sliding bodies 4, 7 sliding against one another, the softer second sliding body 7 wears out preferentially and thus protects the more expensive, longer first sliding body 4 from wear.

A further idea of the inventive sliding gate device or sliding gate linear guide provides that the second material of the second sliding body 7 is preferably self-lubricating. As a result, the upper guide 3 can be operated without external lubricants over its service life and is preferably maintenance-free. The effect of self-lubrication can be realized, for example, by incorporating lubricating particles in an amorphous base material of the second material, or by particles of the second material closing up surface irregularities on the first sliding surface 5 when the sliding gate element 1 is moved, thus ensuring low-friction and maintenance-free operation of the upper guide 3 provide.

The invention is not limited to the illustrated embodiments of the sliding gate device. In particular, the components can be freely selected within wide limits in terms of their shape, dimensioning and arrangement with respect to one another.

Alternative exemplary embodiments for the sliding gate device are formed while retaining the invention, for example in that instead of a first support element 19 in the form of a support post, the upper guide 3 is held on a building wall, a fence post or the like. Furthermore, while retaining the inventive idea, it is possible for the lower guide 2 to roll with its rollers 18 directly on the ground.

In particular, the 1 until 9 illustrated elements of the sliding gate device according to the invention while retaining the inventive idea have a different shape.

It is also conceivable that a sliding gate linear guide according to the invention mounted on the sliding gate device according to the invention can be used as the upper guide 3 of the sliding gate device according to the invention.

Furthermore, the sliding gate linear guide according to the invention or the sliding gate device are not limited to the uses described and can be used in a variety of ways. For example, the sliding gate linear guide can also serve as a guide element for a sliding gate element 1 within a building or a machine housing to guide a sliding door or a sliding wall or a sliding window.

According to an alternative exemplary embodiment of the sliding gate device according to the invention, the lower guide 2 is formed by telescopically extendable pull-out elements which are held between the sliding gate element 1 and the support element 19 or the underbody. Compared to a roller guide, this type of lower guide 2 requires comparatively little maintenance. It is preferably used when Sliding gate element 1 has a maximum length of one meter and consequently a comparatively low weight force to be supported.
