Title: Guide device for a sliding door

description

The invention relates to a guide device fastened to a substructure for a sliding door.

Such guide devices are well known. They generally consist of an essentially circular guide rail, on the top of which a carriage or rollers run. The carriage or the rollers are connected to the sliding door via holding elements. Due to the design, these holding elements can only be provided on one side of the guide rail. This leads to an off-center suspension of the sliding door and is therefore unsatisfactory from a technical point of view. In addition, the entire suspension of the sliding door is optically unsatisfactory, since the rollers and the holding elements are visible from the outside and can only be covered with great effort.

A generic device according to the preamble of claim 1 is known from DE 299 19 191 U1. The known track profile essentially consists of two profiles combined into a one-piece, uniform profile, which form a channel in which the rollers of a carriage can roll. The running surfaces of the rollers practically form an undercut of the profile; since the profile is designed for mounting on a ceiling structure arranged above the profile, two undercuts are provided above the channel receiving the carriages in a side-by-side arrangement, which undertake the fastening elements for connection to the ceiling structure. The well-known track profile sets the accessibility from the top of the ceiling structure

BESTATIGUNGSKOPIE advance in order to be able to insert the fastening elements into the overlaps provided for this purpose.

DE 297 02 221 U1 describes a sliding door slidably arranged on a building wall. The running rail for the sliding door is designed as a circular tube which has a slot in its lower region for the passage of the support elements of the sliding door. With the circular design of the guide rail and an additional seal arranged between the sliding door and the building wall, the penetration of dirt into the guide rail and sealing of the sliding door with respect to the building wall on the one hand and cleaning of the running rail as simple as possible are to be achieved on the one hand ,

It is therefore an object of the present invention to provide a guide device of the type described at the outset, which provides a technically and optically appealing design for a guide device and in particular for mounting on a substructure running parallel to the sliding door, which can be, for example, a glass wall, suitable is.

This object is achieved by the features specified in claim 1. Advantageous further developments result from the subclaims.

According to the invention, a first undercut, which carries idler rollers of a carriage, and a second undercut are arranged offset by 90 ° on the guide rail, the guide rail in the area of the first undercut as a profile part with an arcuately curved front surface and in the area of the second undercut as a profile part is formed on a flat back surface and that the profile part having the first undercut is detachable with the second Undercut profile part is connected. This means that the sliding door can be suspended in the center, so that there is no lateral moment loading the sliding door and the suspension. In addition, the carriage is covered by the guide rail, so that only the guide rail is perceived from the outside. This can be designed in a visually appealing manner and can thus be integrated into the overall picture almost inconspicuously. As a result, there is a satisfactory suspension of the sliding door in both technical and aesthetic terms. In particular, due to the detachability of the two profile parts, an assembly, for. B. on masonry, ie on a substructure not accessible from the back, possible.

To ensure safe guidance of the carriage in the guide rail, the channel is provided with an undercut at its downward-facing open end, the undercut forming two lateral raceways for the carriage in the area of the open end. In this way, the guide rail is additionally narrowed in the lower region, so that the penetration of contaminants into the channel of the guide rail can be largely prevented.

The guide rail is designed as a profile part with a flat back surface and an arcuate curved front surface. The flat back surface enables the guide rail to fit well on the side parts and the rounded front surface underlines the visual impression.

A feature of independent importance is seen in the fact that the support rollers of the carriage are mounted on an axis which extends through a transverse bore of a support body of the carriage and which extends around a center which surrounds the support body in the axial direction of the carriage Axis can be pivoted vertically to a limited extent. With this measure, a secure support of both roles of a roller carriage on both guideways is achieved; This avoids an inclined position of the sliding door if, for example, due to construction tolerances, both roles of a roller carriage do not constantly rest on the assigned guideways.

So that the guide rail can be securely fastened to the side parts, an undercut running in the longitudinal direction of the guide rail is provided in the back surface and serves to receive fastening elements for the guide rail. This undercut enables the fastening elements to be arranged at any point and thus enables simple adaptation to the structural conditions.

Each fastening element has a sliding block, which engages with play in the undercut, so that tolerances can be compensated for quickly and easily.

According to a preferred embodiment, the sliding block interacts with a fastening bolt which passes through the side part and which is held on the side opposite the guide rail in a bearing block in contact with the side part. This enables the guide rail to be securely supported on the side parts, which are preferably made of glass.

In order to enable tolerance compensation in a simple manner, the fastening bolt is advantageously arranged eccentrically or designed as an eccentric. In order to cover the bearing blocks, according to an advantageous development, a common cover strip for the bearing blocks is provided, which can preferably be clipped onto the bearing blocks.

So that no dirt or other contaminants can penetrate into the open ends of the guide rail or the cover strip, the ends of the guide rail and the cover strip can be closed with profile end caps. This also underlines the visual impression of the management facility.

The carriage carrying the sliding door advantageously has two cheeks which rest against the sliding door and are supported by lifting screws in the region of the two ends of the cheeks. This ensures safe storage of the sliding door on the carriage.

According to a preferred embodiment, the carriage has a support body in the central region between the cheeks, which receives an axis, at the ends of which support rollers are mounted, which roll on the lateral tracks in the guide rail. This construction results in a good and safe introduction of force into the guide rail.

The support rollers advantageously lie in recesses in the cheeks and are essentially flush with the outer surfaces of the cheeks. This enables good lateral guidance of the carriage in the guide rail.

According to an advantageous further development, the downward-facing surfaces of the cheeks run outward in an arc shape from the support roller. This prevents the entire structure from coming into contact with the carriage and the guide rail and thus can come to a halt in the sliding movement.

According to a preferred development, the guide rail is fastened to two side parts arranged to the side of the sliding door, which preferably consist of the same material, in particular glass, as the sliding door. Especially in the case of a sliding door that is part of a glass front, the construction according to the invention creates a guide device that does not interfere with the overall visual impression.

Further features and advantages of the invention result from the following description of a preferred exemplary embodiment.

A guide device 5 runs above the sliding door and is attached to the two side parts 1, 2 and optionally also to the skylight 4.

FIG. 2 shows a cross section through the guide device 5 in the region of one of the side parts 1, 2 and through the sliding door 3, while FIG. 3 shows a perspective view of a guide rail 6. The guide rail 6 is provided with a channel 7 which runs in its longitudinal direction and is open at the bottom. This channel 7 is provided in the region of its open end with undercuts 8 projecting laterally into the channel 7, the inner surfaces of which serve as guideways for carriages 9 carrying the sliding door 3. The inner surfaces of the guideways can be straight or crowned.

The guide rail 6 is provided with a flat back surface 10 with which the guide rail 6 rests on the side parts 1, 2. In the back surface 10 there is an undercut 11 running in the longitudinal direction of the guide rail 6, in which fastening elements 12 can engage. The front surface of the guide rail 6 can be rounded for design reasons and to reduce the material.

FIG. 4 shows the guide rail 6 with the associated fastening element 12. In the exemplary embodiment shown, the fastening element 12 consists of two sliding blocks 13 engaging with undercut 11 in the undercut 11, two interacting with the sliding blocks 13 and fastening bolts 14 and 14 penetrating through the side parts 1, 2 a bearing block 15 receiving the fastening bolts 14, which is shown in detail in FIG. In the assembled state, the guide rail 6 rests with its back surface 10 on one side of the side parts 1 and 2, while the bearing blocks 15 rest on the other side of the side parts 1 and 2.

The fastening bolts 14 can be arranged eccentrically or provided with an eccentric to compensate for tolerances and to ensure the exact alignment of the guide rail 6.

Only one fastening element 12 is shown in FIG. 4, although it is clear that a plurality of fastening elements 12 must be arranged at intervals from one another over the length of the guide rail 6. The bearing blocks 15 of all fastening elements 12 can be covered with a common cover strip 16 shown in FIG. 6, which can preferably be clipped into the bearing blocks 15 (cf. FIG. 2). In addition, the cover strip 16 is penetrated by one of the fastening bolts 14, while the other fastening bolt ends in the bearing block 15.

The fastening bolt 14 passing through the cover strip 16 is mounted in a sleeve 17, which in turn is mounted in the cover strip 16. The sleeve 17 is additionally secured with a screw 18 which penetrates the sleeve 17 and ends in the bearing block 15. The fastening bolt 14 passing through the sleeve and the screw 18 are provided with a common decorative cap 19.

In addition, the open ends of the guide rail 6 and the cover strip 16 can be closed with profile end caps 21, 22, which are shown in detail in FIGS. 7 and 8.

To limit the sliding path of the sliding door 3 6 stops 23 can be used in the guide rail, which will be explained later in connection with Figures 12 and 13.

The carriages 9, which carry the sliding door 3, are guided in the channel 7 of the guide rail 6. Such a carriage 9 is shown as a whole in FIG. 9 and in detail in FIGS. 10 and 11.

The carriage 9 consists of two lateral cheeks 24, 25, which are held at a defined distance from one another by a support body 26 arranged in the middle of the cheeks 24, 25, which essentially corresponds to the thickness of the sliding door 3. In its two end regions, the cheeks 24, 25 are provided with bores 27, through which support screws 28 pass, which also pass through the sliding door 6. The heads of the support screws 28 are recessed in the Cheeks 24, 25 arranged so that they do not protrude beyond the outer surface of the cheeks 24, 25.

The support body 26 arranged in the middle between the two cheeks 24, 25 essentially has the shape of a half-cylinder, the straight side of which is pointing upwards and the curved side of which is pointing downwards. On the underside, the support body 26 is provided in the region of its apex with an axis 29 which projects out of the support body 26 on both sides and extends into the region of the cheeks 24, 25. Carrying rollers 30 are mounted on the projecting ends of the axle, which lie in recesses 31 in the cheeks 24, 25 and are arranged essentially flush with the outer surface of the cheeks 24, 25. At the lower edge, the support rollers 30 project beyond the cheeks 24, 25 in order to be able to roll on the spherical guideways in the channel 7.

The lower edges of the cheeks 24, 25, viewed from the support rollers 30, run in an arc to the respective ends (see FIGS. 10 and 11) in order to place the cheeks 24, 25 on the guideways of the undercut 8 during the movement of the sliding door 3 to prevent.

FIG. 12 shows a stopper 23 which can be used in connection with the guide rail 6. FIG. 13 shows the positioning of the stopper 23 in the guide rail 6.

The stopper 23 consists essentially of a U-shaped, downwardly open profile, in the bottom 32 of which clamping elements 33 are inserted, with the aid of which the stopper 23 can be clamped or tilted in the guide rail 6. In the exemplary embodiment shown, the clamping elements 33 are formed by two nuts, with the aid of which a clamping part can be pressed against the bottom of the channel 7. FIG. 14 shows a view of the sliding door 6 in the area of the carriage 9. The recess 34 for the support body 26 arranged in the carriage 9 and the openings 35 for the support screws 28 can be seen.
