Description

The invention relates to a sliding door arrangement with a device for closing the sliding door according to the preamble of claim 1 and a device for driving a sliding door in a sliding door arrangement.

The closing of sliding doors in the private sector, e.g. on cupboards in the bedroom or living area or with sliding doors between individual rooms, is usually done by hand. Sliding doors in the commercial sector, e.g. at entrances to shops or companies, are usually operated by a motor. For this purpose, outside the sliding door, e.g. electrical drives are housed in the frame or in one of the walls surrounding the sliding door, which usually cause the doors to open and close via flexible connections such as chains, ropes or belts or pneumatic elements. The use of electromotive or pneumatic drives for doors in private areas, e.g. to the bathroom or to the kitchen or between two rooms or on cupboards, is often not possible due to cost and space reasons.

Simple closing devices are also known from the prior art, in which the opened sliding door can be closed by a counterweight previously pulled up when opening, which is accommodated in the frame or outside the door. Such devices require a lot of space, which can also impair the width of the door opening and, moreover, such devices must be planned in before planning the doors when planning the building or cabinet and made available at the time of door assembly.

An object of the present invention is now to provide a sliding door arrangement and a device in which the device for closing the sliding door does not have to be planned and installed before the construction of a cabinet, a wall opening or the manufacture of the sliding door, but instead can be retrofitted into a sliding door arrangement at any time.

Another object of the invention is to provide a device that does not require any structural measures and also remains invisible to the user of the sliding door after it has been installed.

These objects are achieved by a sliding door arrangement according to the features of claim 1 and a device according to claim 7. Advantageous embodiments of the sliding door arrangement and the device are described in the dependent claims.

According to the invention, a sliding door arrangement with a device for closing the sliding door is proposed, comprising a sliding door arrangement for a sliding door with a device for closing the sliding door, comprising a sliding door with at least two trolleys which are designed to be connectable with bases to the sliding door, and a guide rail in which the trolleys are guided in a rollable manner and a guide slot in the guide rail, through which the drive trolleys can be connected to the bases with the sliding door and slidably support the sliding door, the sliding door being mounted on pairs of rollers between the spaced-apart parts attached to the sliding door carrying trolley the device for closing the sliding door can be used. According to an advantageous embodiment of the invention, the device can be connected to a carriage.

According to a further advantageous embodiment, the device can be connected to the sliding door.

According to a further advantageous embodiment of the invention, the device can be arranged displaceably within the guide rail.

In a further advantageous embodiment, a rotation damper for reducing the driving speed of the sliding door during the travel path of the sliding door is installed on the device.

According to a further advantageous embodiment of the invention, the device is designed to be insertable into the guide rail through the guide slot.

According to the invention a device is proposed for closing the sliding door in a sliding door arrangement, comprising a housing with a rotatably mounted first stationary pulley battery and a second pulley battery rotatably mounted in a pulley housing, the pulley housing in the housing of the device is displaceably guided, further comprising a tension spring, which is fastened on the one hand to the housing of the device and on the other hand to the cable reel housing, and a traction cable which is looped around the rollers of the two cable reel batteries and with the first end with the housing and with the other end directly or is indirectly connected to the guide rail.

According to an advantageous embodiment of the invention it is provided that the housing has a U-shaped cross section, in which the first cable reel battery is rotatably mounted on a shaft mounted in the housing and in which the cable reel housing with the cable reel battery is slidably arranged.

According to a further advantageous embodiment of the invention it is provided that a tension spring is inserted between the cable reel housing and the housing, which tension spring can be tensioned by a pull rope wrapping around the two cable reel batteries.

According to a further advantageous embodiment of the invention it is provided that the tension spring on the one hand is attached to the displaceable cable reel housing and on the other hand directly or indirectly to the housing.

CH 715 230 A1 [0011] By designing the entire device for closing the sliding door arrangement, the sliding door can be inserted between the drives that carry the sliding door. Since there is always adequate space there, at any time, i.e. Before the initial assembly of the sliding door, during the initial assembly of the sliding door and also at a later time, a locking device must be installed. Due to the advantageous construction of the device, it can be inserted through the guide slot of the already mounted guide rail and arranged inside the guide rail for the carriage, so that the device also remains invisible from the outside. A spring element is sufficient as an energy store for closing the door, be it one or more coil springs or a pneumatic cylinder with a sufficient stroke corresponding to the width of the sliding door. In order to obtain the travel path corresponding to the width of the sliding door, a cable pull is used in a housing accommodating the device. Preferably, stationary rollers of the cable pull are rotatably held directly by the housing of the device and the movable rollers are guided longitudinally into the housing in a special roller cage. The connection from the device which travels with the sliding door to the guide rail takes place for the rope arranged on the cable pull by means of a clamp or the like in the guide rail and / or on the door frame. A metallic wire or a product made of synthetic fibers or carbon fibers can be used as the material for the rope.

Furthermore, the locking device also enables the simultaneous installation of a retaining device with the sliding door open and a damping device, which at the end of the closing process suppresses a hard opening and thus suppresses noise and prevents the sliding door from accelerating too much during the closing process. A commercially available brake roller in the form of a rotary damper can be attached to the housing of the device as the damping device.

The low-friction design of the closing device makes it possible to carry out the closing movement by means of an energy store, which can be loaded with little effort when the sliding door is opened. In other words, opening the door provided with the locking device requires only insignificantly higher sliding forces than a sliding door without such a device.

The locking device can be attached to sliding doors which are carried hanging from a rail at the top or to those which are supported standing on the lower edge of the sliding door in a guide rail without adaptation.

Due to the possibility of installing the device through the guide slot on the guide rail in the latter, the installation can consequently be carried out without problems on the guide rails already mounted by the sliding door opening. The guide rail therefore no longer has to be dismantled for the insertion of the device.

The manufacturing costs of the locking device are extremely low, since it consists of a few inexpensively procured parts or is constructed.

The device for closing the sliding door is motorless and therefore no energy supply in the form of electricity and the like from the outside is necessary.

The invention is explained in more detail with the aid of an illustrated embodiment. It shows:

Fig. 7 is a perspective view of the movable cable reel holder.

In Fig. 1, with the omission of a door frame or a cabinet opening, a closed sliding door 1 or the upper area comprising the upper edge is visible. On the upper edge 3 of the sliding door 1, two carriage 5 known type are attached. The attachment of the base 7 of the two carriage 5 on the sliding door 1 is carried out in a known manner by screws or by a quick release. Screws or quick fasteners are not shown. The carriage 5 comprise at least one pair of rollers 9, comprising two rollers spaced apart on an axis. Preferably, and in view of an optimal load distribution, two pairs of rollers 7 are arranged per carriage 5. The two carriage 5 are spaced from each other in the vicinity of the side edges 9 and 11 of the sliding door 1 attached to the upper edge 3. As shown in Fig. 1, the rollers of the carriage 5 are mounted in a guide rail 13 rollable. The guide rail 13 comprises a double C-för

CH 715 230 A1 moderate cross section, as can be clearly seen in the section according to FIG. 6. The rollers of the pairs of rollers 9 roll on the legs 15 which run essentially parallel to one another. The guide rail 13 is usually attached to its base leg 17 with the ceiling of a cabinet or a room or in the door opening of a wall. The guide rail 13 is fastened in a conventional manner with screws or a click system which enables screwless fastening (click system not shown). In Fig. 1, the running rail 13 is cut vertically apart from the short area A in half, in order to be able to represent the position of the two carriage 5 in the guide rail 13.

Between the two carriage 5, a device for closing the sliding door 1 is visible with reference numeral 19. In the example, the device 19 comprises a U-shaped housing 21. The housing 21 is shown cut away in sections in FIGS. 1 to 3 in order to allow an unobstructed view of the cable reel housing 23 with the cable reel battery 25. The cable pulley housing 23 is shown in FIG. 7. In addition to a cable reel battery 25, which is rotatably mounted on a shaft 27 in the side walls of the cable reel housing 23, the cable reel housing 23 comprises a clamping means, for example a clamping screw 29, for clamping the first end of a traction cable 31. Furthermore, on the two side walls of the cable reel housing 23 Wirrwlies- or felt pads 33 are attached, which protrude slightly from the side surfaces. The width B of the cable reel housing 23 is increased by the two felt pads 33. From Fig. 6 it can be seen that the cable reel housing 23 with the cable reel battery 25 in the housing 21 of the device is both guided laterally and is slidably supported on the bottom. The two felt pads 33 cause the cable reel housing 23 to be laterally displaceably mounted in the housing 21 of the device without play. In order to reduce the sliding resistance, felt or the like can also be attached to the underside of the cable reel housing 23. Noises when moving the device 19 in the guide rail 13 are consequently substantially prevented. The device 19 or its housing 21 can carry on its front, in the figures at the left end, a roller 35, the periphery of which is radially elastic, e.g. wearing a rubber covering or a rubber ring. The roller 35 is rotatably mounted on the side of the housing 21. The rotational movement of the roller 35 is controlled by suitable means, for example a rotary damper with a freewheel. The lateral arrangement of the roller 35 is selected such that its periphery, which projects slightly below the housing 21 at the bottom, lies frictionally on the horizontal leg 15 of the guide rail 13.

Furthermore, a coupling element 37 is formed on the housing 21 of the device 19, at least at its left end, with which the device 19 can be connected to the drive carriage 5 arranged on the left, near the side edge 11 of the sliding door 1. The connection to the drive carriage 5 can be fastened by suitable connecting elements present there. Through this connection and possibly an analog coupling element 37 at the rear end of the housing 21, which can be connected to the rear carriage 5, the device 19 is carried within the guide rail 13 by the carriage 5.

In order to enable simple assembly, the at least one coupling element 37 is displaceably mounted on the housing 21 and, after being connected to the respective carriage 5, can be permanently connected using one or more fixing screws 39. The coupling element 37 can, for example, as shown in FIG. 6, be arranged to be longitudinally movable in a guide space 41 slotted at the bottom on the housing 21. The displaceability of the coupling element 37 enables the device 19 to be used on sliding doors 1 of different widths.

As an alternative to fastening the device 19 to at least one carriage 5, the device 19 could also be fastened between the two carriage 5 on the upper edge 3 of the sliding door 1. However, the first-mentioned and described type of fastening is preferably treated, since the device 19 can be inserted simultaneously when the carriage 5 is inserted into the guide rail 13.

On the cable reel batteries 25 in the movable cable reel housing 23 and a second substantially identical cable reel battery 43, which is mounted on a shaft 45 at the rear end (right side in the figures), the pull cable 31 is guided. For this purpose, in the two cable reel batteries 25, 43, e.g. In each case, three rope pulleys are arranged next to one another, with circumferential recesses 47. The depth of the recesses 47 are dimensioned such that a pull rope 31 inserted into them does not project beyond the periphery of the rope pulleys, i.e. is protected inside the punctures 47. The e.g. three rope pulleys are preferably spaced from each other so that they can rotate independently of one another at different speeds.

One end of the pull rope 31 is attached to the rope reel housing 23. The other end is led out of the device 19 and at the left end of the guide rail 13 by suitable means, e.g. a clamping screw. The clamping screw is not shown for the sake of clarity.

Another fastening option can be provided on a retaining element 49, which is fastened to the guide rail 13 at the front, left end thereof. The retaining element 49 comprises an elastic retaining lever 51 which, after the carriage 3 has hit, can latch in when the door is closed (see FIG. 1) and consequently holds the sliding door 1 in the closed position.

The sliding door 1 is pulled into the end position (closed sliding door 1) by a spring element, in particular one or more coil springs 53. The tension spring 53, which on the one hand engages the cable reel housing 23 and on the other hand is connected to the front end of the housing 21, pulls the two cable reel batteries 25 and 43 apart and thereby shortens the free end of the pull cable 31, which is connected to the front end of the guide rail 13 .

The functioning of the device 19 is explained in more detail below.

CH 715 230 A1

The starting point is a closed sliding door 1 (FIG. 1), which, if present, is positioned in the closed position by a retaining lever 51. After overcoming the holding force of the retaining lever 51 by manually pushing the sliding door 1 in the direction of the arrow P (FIG. 1), the tension spring 53 is tensioned in the device 19 because the displaceable cable roller housing 23 by pulling out cable material which is between the two cable roller batteries 25 and 43 is stored, brings the two cable reel batteries 25, 43 closer together and thereby pulls the tension spring 53 apart. The opening of the sliding door 1 is consequently associated with a force which is greater than the force for overcoming the rolling resistance of the two drive carriages 5. When the sliding door 1 is in the fully open position, i.e. On the far right in FIG. 2, the sliding door 1 is in turn held on a retaining element 49 by a retaining lever 51. The two retaining elements 49 at the ends of the guide rail 13 are preferably of identical design.

In order to close the sliding door 1 again, the restraining force of the restraining lever 51 arranged on the right must first be overcome, as when opening. If this has happened, the tension spring 31 previously tensioned when opening pulls out the pull rope running over the two cable reel batteries 25 and 43, and consequently the strand of the pull rope 31 which is to the left end of the guide rail 13, e.g. attached to the retaining element 49, which is arranged there, and the sliding door 1 moves to the left. Without the damper roller 35, which dampens the driving speed of the sliding door 1, the latter would accelerate and impact against the left-hand retaining element 49. Braked by the damper roller 35, the sliding door 1 slides to the left essentially at a constant speed and is also held more slowly by the retaining lever 51 at the end of the travel movement due to the decrease in the energy stored in the tension spring 31.
