EP3909483B1 - Device for adjusting a door and shower cubicle - Google Patents

Description

The invention relates to a device for adjusting a door with a door profile on a wall or a fixed panel element according to the preamble of claim 1, as well as a shower cubicle or a shower partition according to the preamble of claim 6 with such a device.

Such devices are known as fittings or hinges and are used, for example, in EP 2 228 510 B1 disclosed. They are used to attach the door to a wall or a fixed panel element and often also have support surfaces and complementary support surfaces to raise or lower the door during the opening and closing process (lifting and lowering mechanism). These support surfaces and complementary support surfaces also cause the door to automatically move into an open position or a closed position and come to rest there. Raising and lowering the door has the advantage that, for example, seals attached to the lower end of the door do not brush against the floor when the door is opened and closed, but are lifted away from it. This is necessary to ensure that the door can be moved without problems and to increase the service life of the seal. In order to be able to set the open or closed position of the door precisely, the fittings shown in the prior art have adjustment devices.

In the case of EP 2 228 510 B1 This adjustment option is provided by a clamping ring. The clamping ring encloses a lifting sleeve, which can be secured in the clamping ring in a twist-proof manner by pulling the clamping ring together. The lifting sleeve, which can be fixed in this way, has adjustment surfaces which cause the door to be raised and lowered. When the door is lowered, it is in the closed or open position due to the adjustment surfaces. If the door is aligned with the frame of the shower cubicle or shower partition and remains in the closed or open position at the correct angle, this position must be adjustable. The clamping ring is opened so far that the lifting sleeve can be rotated relative to the clamping ring. When the desired position is reached, the lifting sleeve is clamped by pulling the ring together and thus the position of the door is fixed. The problem here is that the clamping ring must be connected to the frame profile or support profile and at the same time must be sufficiently flexible to ensure that the clamping ring can be opened and closed. In the current state of the art, this is achieved by inserting the clamping ring into a hinge plate. However, the indirect contact with the support profile by inserting it into the hinge plate does not guarantee that the door will be mounted without play. If the clamping ring is pulled together, its circumference, which must engage with the hinge plate, also changes. If the clamping ring is pulled together, its circumference and shape are reduced and the gap to the corresponding area of the hinge plate increases. The clamping ring can therefore no longer form a play-free connection with the hinge plate. Furthermore, the structure of the fitting, the clamping ring and the lifting sleeve, which is open at the top, offers the possibility of water ingress and thus contamination in the area of the hinge plate. Therefore, after prolonged use of the shower cubicle, the proper functioning of the adjustment can no longer be guaranteed due to play or the entry of contaminants such as soap residue or limescale.

It is also known that a lifting and lowering mechanism is adjusted using a clamping screw. Subsequent angle adjustment is usually not possible, as the clamping screw would cause marks on the bearing parts. Such marks hinder or impair subsequent angle adjustment. In addition, with these clamps there is a risk that the angle position of the lifting and lowering mechanism changes during daily use. Such a device is used, for example, in the WO 2006/054942 A1 Another variant of such a device is disclosed in EP 2 447 453 A1 described. Fittings are also known that use clamping rings. The lifting sleeve should be able to be fixed against rotation relative to a lower joint plate by means of a clamping effect, with a clamping ring being interposed between the lower joint plate and the lifting sleeve. A variant with the same effect is also used in the AT 517844 A4 (2017-05-15 ) described.

Other adjustment options, such as worm gears, etc. are not free of play.

In the EP 1 712 717 A2 A fitting for fastening a door leaf is described, whereby a fine adjustment of a first locking profile can be carried out via the screws and manipulation flanks.

In the DE 297 04 719 U1 a shower partition is revealed. The locking position of the door is adjusted using a locking part.

In the DE 297 04 621 U1 A device for the pivotable mounting of a shower door is described. An adjustment device that can be operated from the outside is provided for adjusting the height of a lifting ring.

In the EN 10 2013 209 178 A1 A hinge for the door leaf of a shower partition is disclosed, which prevents the door leaf from hitting the door without braking and allows the door leaf to be braked gently. A rotation brake is provided for this purpose, with the rotation brake and a compression spring being arranged on a hinge pin.

In the DE 201 05 282 U1 a swivel bearing is stressed. To determine the rotational position, a locking element engages in a radial recess of an intermediate piece.

In contrast, the invention is based on the technical problem of specifying a device of the type described above with which shower doors can be transferred from any angular position in the closed state to the open or raised state in a functionally reliable and problem-free manner.

The invention is based on the finding that a device according to the invention enables a variable and stepless adjustment in a simple and precise manner, as well as locking the door in a wide variety of angular positions. This makes it possible to move the shower door from any angular position of the closed state to the open or raised state. The device according to the invention can be used to adjust angular orientations for shower doors of typical shower cubicles with a rectangular cross-section and, on the other hand, any angular orientation or intermediate angular position can be set in a functionally reliable manner.

This applies in particular to shower cubicles with, for example, a polygonal cross-section or for shower cubicles with a round cross-section. The device according to the invention enables optimal and functionally reliable adaptation to the specific on-site situation. Due to the preferably symmetrical or quasi-symmetrical design of the fitting with regard to its lower and upper ends, shower doors connected to the devices according to the invention can be used in a simple and problem-free manner as reversible doors for right-hand and left-hand hinges.

The object of the invention is to avoid the disadvantages described above and to provide a device which is improved compared to the prior art or a shower cubicle or shower partition with such a device which is improved compared to the prior art.

This is achieved in the device according to the invention by the features of the characterizing part of claim 1 and claim 6.

Accordingly, the invention relates to a device for adjusting a door, wherein the door is connected to a wall or fixed panel element and comprises a bearing part which is connected to the wall or fixed panel element, wherein a bearing lifter is arranged in the bearing part, which has at least one setting surface for raising and lowering the door during the opening and closing process of the door, which is in an operative connection with at least one complementary setting surface arranged on a door lifter. It is advantageously provided that the bearing lifter has bevelled, rocker-like surfaces on the side opposite the setting surface and a tensioner is provided as a force transmitter, which is connected to the bearing lifter, wherein the tensioner is movably mounted in the bearing part and an adjustment means is provided in the bearing part for adjustment, which can be designed as an adjustment screw. An adjustment screw and a locking screw are advantageously provided in the bearing part for this purpose.

The continuous and play-free adjustment of a door leaf with a lifting and lowering mechanism via a pre-tensioned rocker has the following advantages over previously known adjustments: With just one screw, the pre-tensioned rocker enables a simple and play-free angle adjustment of a door leaf with a lifting and lowering mechanism. This means that multiple angle changes, even minimal ones, can be made. The angle adjustments can be held 100% using the rocker.

According to a special feature of the invention, the tensioner is designed as spring steel or as a compression spring. The bearing lifter can be moved about a vertical axis via the adjusting screw, whereby the tensioner is tensioned and the angular position of the door can be adjusted, whereby the adjustment of the door can then be secured via the locking screw 7.

The invention relates to a device for simple, play-free, stepless adjustment of a door leaf with a lifting and lowering mechanism using a so-called pre-tensioned rocker. The invention can be used both for a connection of the fixed panel part to the door or the door to a wall. The device can be installed in a direct wall connection to the door, in a fixed panel connection to the door or in a fitting. The doors and fixed panels can of course be installed at different angles to each other. (Flush, at a 90° angle, etc.)

The parts of the device are in the Fig.1 shown in the exploded view.

The neutral position of the door leaf 13 (lifting curve below) can be changed with an adjustment tool 6 by turning only one screw ( Fig.2 ).

The assembly comprising the device is mounted in the unclamped position. Two bevelled surfaces of the bearing lifter 2 are referred to as the rocker 2.1. The bearing lifter 2 with the rocker 2.1 (bevelled surfaces) is mounted in the bearing 1 with a tensioner 3 (spring steel), whereby the surfaces of the bearing 1 opposite the bevelled surfaces of the rocker 2.1 are also bevelled. The tensioner 3 is firmly connected to the bearing lifter. The tensioner 3 is pressed firmly into the bearing lifter 2 using a so-called press fit and sits firmly there. This assembly is then inserted into the bearing part 1, where the tensioner is mounted in a form-fitting manner with a slight play. The tensioner 3 is therefore mounted in a movable (sliding) manner in the bearing 1. The door 13 is at an angle ( Fig.3 ).

By turning the adjustment tool 6, the bearing lifter 2 with the rocker 2.1 is moved around a vertical axis via the adjustment screw 4 and is in the neutral control position ( Fig.4 - Delivery condition). The tensioner 3 is pre-tensioned.

The bearing lifter 2 can be moved further around the vertical axis by further turning the adjusting screw 4 using the adjusting tool 6. The neutral position of the door leaf 13 (lifter curve below) is thereby further changed ( Fig.5 ).

The force of the pre-tensioned tensioner 3 moves the door leaf 13 back and forth between the maximum and the neutral (untensioned) position by turning the adjustment screw 4. The maximum adjustment is determined by the angle and dimensions of the construction. In shower cubicle construction, +/-10° is usually sufficient for adjustability. After adjusting the door leaf 13, it is secured by the locking screw 7 and the adjustment opening 1.3 around bearing 1 is covered by the cover 8. Fig.6 shows a vertical section of the device and the door 13 with the fixed panel or wall profile. The door 13 is lifted vertically upwards via the lifting curve 14.1 of the door lifter 14 and the lifting curve 2.2 of the adjustable bearing lifter 2. The adjusting screw 4, the locking screw 7 and the tensioner 3 are clearly visible.

Any means that can be used as a force generator can be used as a tensioner. As can be seen from the Figs. 7 - 9 As can be seen, the preload can also be generated using a compression spring instead of a spring steel.
