EP1043469A1 - Sliding wall element, especially for a stackable sliding wall - Google Patents

Abstract

The floor guide (22) can adjust within the wall panel (11) and can deflect to either side from a pre-set rest position again re-set spring. In its rest position the guide (22) stands vertically below the driven panel-top rail (17) carriage (19). The gui deflects both ways parallel to the bottom panel edge against coil re-set springs and is fixed to a slider which moves in a base releasably fitted to the wall panel. The panel bottom edge consists of a hollow profile grooved lengthways so the slider and bas can be inserted and releasably fixed in the groove. The slider presents a longways block milled out lengthways to take the slide block base and the prescribed re-set springs.

Description

TECHNICAL AREA

The present invention relates to the field of movable room dividers. It relates to a sliding wall element, in particular for a sliding stack wall, which wall element on the ceiling side by means of carriages in a track is movably supported, and which wall element by means of the bottom of a guide element in a extending parallel to the running rail Guide rail is guided, one of the carriages for automatic movement the wall element is equipped with a motor drive.

A sliding stack wall with wall elements of this type is used by the applicant marketed under the name "HAWA-matic 150A".

STATE OF THE ART

Sliding walls with motor-driven individual wall elements have long been known (see e.g. DE-C2-26 43 905 or DE-C3-24 04 875, in which, however, wall elements without bottom-side guidance are disclosed become). Such a wall element has the basic structure shown in FIG. 1. The wall element 11, which is part of a sliding stacking wall 10, comprises - if the wall is designed as a glass wall - a glass plate 12, at least is mounted on the upper and lower edge in a hollow profile 13 and 14, respectively. The Hollow profiles 13, 14 are usually extruded aluminum profiles. One on the market exemplary lower hollow profile 14 is shown in cross section in Fig. 2.

On the upper hollow section 13 (usually two) are equipped with wheels or rollers Carriages 19 and 20 attached, by means of which the wall element 11 is easily displaceable is mounted in a running rail 17 which runs concealed in the ceiling 16, but can also be arranged hanging just below the ceiling 16. One of the carriages 19, 20, in the example shown the left carriage 19, has an integrated motor drive, which runs parallel to the running rail 17 Busbars and corresponding sliding contacts supplied with power and is controlled by a central controller (see e.g. WO-A1-97 / 42388).

So that the wall element 11 is guided stably and safely during the automatic method is, and the wall formed from the individual wall elements 11 is not transverse can be moved or pushed away to the wall plane is corresponding a guide rail to the ceiling-side running rail 17 in or on the floor 15 18 provided, in which the wall element 11 with a bolt-like, vertical engages downwardly projecting guide element 22. The guide element 22 is - as can be seen from Fig. 2 - screwed into a guide insert 21. The guide insert 21 in turn is laterally in a with a dovetail guide equipped groove 23 inserted in the lower hollow profile 14 and clamped in the groove 23 by one or more locking screws. In order to disturbing tilting moments during the motor-driven movement of the Wall element 11 are avoided, the guide element 22 is practical arranged vertically below the driven carriage 19.

In practice, it has now been found that despite these precautions Disruptions in the movement of the wall elements 11 can come because of the Tilt wall elements when moving under certain circumstances, see above that the movement is hindered and the motor drive then due to the Switches off when a predetermined load limit is exceeded. The disabilities in the movement of the wall elements can have different causes especially in the non-ideal parallelism of the running rail 17 and guide rail 18 lie. Two of the possible causes are described below using the schematic 3 and 4 are explained:

Because a movable wall often extends over a length of 10, 20, 30 m or can extend more, it is difficult to guide rail 17 in the ceiling to be installed so that it runs continuously on one level. Indicates the guide rail 17, for example, a curvature - shown in a greatly exaggerated manner in FIG. 3 in the vertical direction, the carriages 19 and 20 a wall element 11 with a different distance from the upper edge of the wall element 11 are adjusted to the wall element at its rest position to hang vertically in the closed wall (in the example the 3 is the distance between the carriage 20 and the upper edge of the wall element 11 shorter than the distance of the carriage 19). Now the wall element 11 in Move to the right in the direction of the arrow, it tilts in the manner shown, see above that the guide element 22 is no longer perpendicular to the driven Carriage 19 is located. This can hinder the travel process and finally come to an emergency shutdown.

Another type of disability can occur in the areas of the driveway, in which the rails 17, 18 describe an arc (Fig. 4), such as this is the case in the area of the parking zone of the wall elements (see e.g. also Fig. 5 of DE-C3-24 04 875). Since the wall element 11 below only on one side leads to unwanted canting.

PRESENTATION OF THE INVENTION

It is therefore an object of the invention to provide a wall element in which the disadvantages described are avoided, and which in particular in its movement behavior is insensitive to misalignments the running and guide rails as well as those critical areas, in which the rails follow a curved course.

The object is achieved by the entirety of the features of claim 1. The essence of the invention is that the guide element in the wall element so to store that it perform evasive movements relative to the wall element can, if this is necessary in the event of impending tilting of the wall element should be. As a result, flexibility in leadership is achieved, critical Conditions in the movement of the wall element with simple means safely avoids.

So that the guide function by the slidable mounting of the guide element itself is not affected or is affected only slightly, according to a first preferred embodiment of the invention provided that the guide element assumes a predetermined rest position in the sliding storage and can be deflected from this rest position against a restoring force, and that the rest position is arranged vertically below the driven carriage. This ensures that the wall element under normal circumstances is guided to the desired extent on the ground, while impending Canting temporarily an evasive movement of the guide element is possible relative to the wall element.

Practical testing has shown that it can be moved of the guide element in all three spatial directions for a successful Preventing canting conditions is not necessary. A second preferred The embodiment of the wall element according to the invention is therefore characterized characterized in that the guide element parallel to the lower edge of the Wall element is deflectable in both directions.

In principle, the restoring forces for the guide element can be used of rubber-elastic materials or the like. Are produced. However, to be exact defined and constant restoring forces are to be obtained over a longer period of time according to a further preferred embodiment of the invention for generation the restoring force spring elements, preferably in the form of spiral springs intended.

Another preferred embodiment of the wall element according to the invention is characterized in that the guide element on a sliding element is attached, which sliding element parallel to the lower edge of the wall element is slidably mounted on a base element such that the base element is detachable is attached to the wall element that the lower edge of the wall element by a hollow profile is formed, which has a longitudinally extending groove and that the base element with the sliding element and the guide element can be inserted into the groove and detachably fixed there. The different Parts (guide element, sliding element and base element) form one coherent management assignment, which is easy outside of the Wall element pre-assembled and in the fully assembled state easily into the lower Hollow rail of the wall element inserted and releasably attached there can.

A particularly compact guide insert results if according to a preferred one Development of the embodiment of the sliding element as in the direction of displacement extending elongated block is formed, the sliding element has an elongated cutout extending in the direction of displacement, in which cutout the base element reaches in the middle with a bearing block, and in the cutout on both sides of the bearing block in the longitudinal direction of spiral springs are stored, which with one end on the sliding element and with support the other end on the bearing block.

Basically, it is conceivable that the sliding element on or in the base element is led itself. However, this would require additional, precise editing steps require in the manufacture of the base element. It is therefore manufacturing technology cheaper if, according to another preferred embodiment Adjusted sliding element in its cross-sectional profile of the groove of the lower hollow profile is and is slidably guided in this groove, and the sliding element from one There is material which is slidable with the material of the lower hollow profile Forms material combination.

A particularly smooth guidance ultimately results, if preferred the guide element comprises a screw bolt which is screwed into the sliding element and with an axis vertically downwards from the sliding element stands out on which axis a roller is rotatably mounted.

Further embodiments result from the dependent claims.

WAYS OF CARRYING OUT THE INVENTION

5 to 8 are different views of a preferred embodiment of the wall element according to the invention with built-in bottom Guided tour. The starting point is a lower hollow profile 14 ', which has practically the same cross-sectional profile as that shown in FIG. 2 known hollow profile 14. The hollow profile 14 'has a groove open at the bottom 23 with a dovetail guide, into which, according to FIG. 5, not only the one according to the invention Guide insert 26 is inserted and releasably attached, but also a locking insert 24 with a locking bolt protruding laterally 25, the neighboring when pushing together in a known manner Wall elements engages in a hole in the neighboring element and so causes a positive connection of both wall elements.

The guide insert 26 comprises a base element 27, which has a cross-sectional profile is adapted to the dovetail guide of the groove 23, and which is inserted laterally into the groove 23 and by means of two locking screws 37, 38 (Fig. 5) can be determined. In the area of the locking screws 37, 38 closes the base element 27 on the underside flush with the underside of the Hollow profile 14 '. To the left of it there is a step into the Base element 27 milled. This creates a higher level 42, in the Area a block-like sliding element 33 is mounted to be longitudinally displaceable. The Sliding element 33 is dimensioned in height so that it is with its underside also ends flush with the underside of the hollow profile 14 '. From the Level 42 protrudes downward in the middle area, preferably a bearing block 28 is molded onto the base element 27 and e.g. when milling out the Step can be generated by leaving the material. The bearing block 28 serves on the one hand to slide the sliding element 33 loosely and captively on To fasten base element 27. On the other hand, the bearing block 28 serves as a support surface and holder for two coil springs 31 and 32, which in the longitudinal direction of the Hollow profile 14 'are arranged on both sides of the bearing block 28.

As can be seen in the top view of FIG. 6, the block-like sliding element 33 an elongated cut 39 extending in the longitudinal direction, into which protrudes from the middle of the bearing block 28, and which on both sides of the Bearing block 28 receives the two coil springs 31, 32. The coil springs 31, 32 are sized so that they are slightly under tension with their one (inner) ends on the bearing block 28 and with their other (outer) Ends on the end walls of the milling 39, i.e. on the sliding element 33, support. If the sliding element 33 is moved to the left relative to the base element 27, the coil spring 32 is compressed and the coil spring 31 is relieved, so that there is a corresponding rightward restoring force. However, if the sliding element 33 is displaced to the right relative to the base element 27, the coil spring 31 is compressed and the coil spring 32 is relieved, so that there is a corresponding restoring force directed to the left. The rest position is defined by the fact that the forces of both spiral springs are in it 31, 32 cancel each other out.

A jumping out of the spiral springs 31, 32 from the milled 39 upwards is prevented in the assembled state of the guide insert 26 that the milling 39 upwards largely through the base element 27 is covered. So that the spiral springs 31, 32 do not slip on the bearing block 28 is one that extends through the bearing block 28 in the direction of displacement Pen, in particular in the form of a gag grooved pin 29, provided which the coil springs 31, 32 pushed with their bearing block ends are. Attachment of the sliding element 33 to the base element 27 taking into account The degree of freedom necessary for the displaceability is thereby achieved that in the sliding element 33 on the long sides of the milling 39 in the Walls extending elongated holes 34 are provided parallel to the direction of displacement into which the bearing block 28 with a transverse guide pin, in particular a roll pin 30 inserted transversely into the guide block 28, intervenes.

The actual longitudinal guidance of the sliding element 33 takes place in the groove 23 itself. For this purpose, the sliding element 33 is in its cross-sectional profile of the groove 23 of the lower one Hollow profile 14 'adjusted and slidably guided in this groove. At the same time the sliding element 33 made of a material which is identical to the material of the lower one Hollow profile 14 'forms a slidable combination of materials. If the lower hollow profile 14 'is an extruded aluminum profile, it has been proven that the sliding element made of a plastic, preferably a polyacetal, in particular POM, consists.

The actual guide element 22 comprises a screw bolt 35, which in the Sliding element 33 is screwed into a part projecting beyond the base element 27 and with an axis 41 vertically downwards from the sliding element 33 and the lower hollow profile 14 'protrudes. There is a roller 36 on the axis rotatably mounted, which is preferably made of a plastic and a lightweight Slidability of the guide element 22 in the bottom guide rail 18 ensures.

Another, particularly simple to manufacture and compact embodiment for a guide insert with a movably mounted guide element is in different views shown in FIGS. 9 to 11. Here too the Guide insert 43 which can be fastened in the hollow profile 14 'by means of a threaded pin 48 Base element (bearing piece) 49 and an elongated sliding element 44, the is slidably mounted in the hollow profile 14 'relative to the base element 49. At the front end of the sliding element 44 is provided with a bolt and roller Guide element 45 attached. To generate a restoring force when deflected of the sliding element 44 relative to the base element 49 are also in this Example two coil springs 50 are provided. The coil springs 50 are in one Through hole 51 stored, which extends in the longitudinal direction through the sliding element 44 extends through. The coil springs 50 are supported with the outer ends in a simple manner on two dowel pins 47, which are vertical in the sliding element 44 are inserted through the through hole 51. With the inner ends the coil springs 50 are seated on corresponding projections of a bearing block 53, with which the base element 49 protrudes into a cutout 52 in the sliding element 44.

With the invention, a guide insert with a cant preventing Slidable guide element available that is compact, easy to move pre-assemble and install in existing wall elements with standard hollow profiles can, and which can be easily adjusted so that the Rest position of the guide element perpendicularly below the motor-driven one Carriage is located.
