Description

The invention relates to a device for adjusting a door with a door profile on a wall or fixed panel element according to the preamble of claim 1, and a shower cubicle or a shower partition according to the preamble of claim 8 with such a device.

Such devices are known as so-called fittings or hinges and are 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 shelves and complementary shelves to raise or lower the door during the opening and closing process (raising and lowering mechanism). These shelves and complementary shelves have the additional effect that the door automatically moves into an open position or a closed position and comes to rest there. The raising and lowering of the door has the advantage that, for example, seals attached to the lower end of the door do not rub against the floor when the door is opened and closed, but are lifted away from it. This is required to ensure that the door can be moved smoothly and to increase the service life of the seal. In order to be able to set the open or closed position of the door exactly, the fittings shown in the prior art have setting devices.

In case of EP 2 228 510 B1 this adjustment option is given by a clamping ring. The clamping ring encloses a lifting sleeve, which can be secured against rotation in the clamping ring by pulling the clamping ring together. The lifting sleeve that can be fixed in this way has surfaces that cause the door to be raised and lowered. When the door is lowered, it is in the closed or open position due to the shelves. Should the door be flush with the frame of the shower cubicle or shower enclosure and remain at the correct angle in the closed or open position, it shall be possible to adjust that position. 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 contracting the ring and thus the position of the door is fixed. The problem here is that the clamping ring must on the one hand be connected to the frame profile or carrier profile and at the same time should also have sufficient flexibility to be able to ensure that the clamping ring can be opened and closed. In the prior art, this is achieved by inserting the clamping ring into a joint plate. However, due to the indirect contact with the carrier profile by inserting it into the joint plate, the door cannot be supported without play. If the clamping ring is pulled together, its circumference, which must be in engagement with the joint plate, also changes. When the clamping ring is contracted, its circumference and shape are reduced and the gap to the corresponding area of the joint plate is thus increased. The clamping ring can therefore no longer form a play-free connection with the joint 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 joint plate. Thus, after prolonged use of the shower cubicle due to play or the entry of contamination such as soap residue or limescale, proper functioning of the adjustment can no longer be guaranteed.

It is also known that a lifting and lowering mechanism is adjusted via a clamping screw. A subsequent angle adjustment is usually not possible, since the clamping screw would cause imprints on the bearing parts. Such imprints cause a hindrance or impairment of a subsequent angle adjustment. In addition, with these clamps there is a risk that the angular position of the lifting and lowering mechanism will change during daily use. Such a device is for example in WO 2006/054942 A1 disclosed. Another variant of such a device is in the EP 2 447 453 A1 described. In addition, fittings are known that use clamping rings. In this case, the lifting sleeve should be able to be secured against rotation with respect 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 AT517844A4 (2017-05-15) described.

Other adjustment variants, such as e.g. via worm wheels etc. are not free of play.

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 with a device according to the invention, variable and stepless adjustment is possible in a simple and precise manner, as well as locking of the door in a wide variety of angular positions. This makes it possible to close the shower door from any angle State to convert into the open or raised state. With the device according to the invention, on the one hand, angular orientations for shower doors of typical shower cubicles with a rectangular cross section can be set and, on the other hand, any desired angular orientations or angular intermediate positions can be set in a functionally reliable manner.

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

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

This is achieved in the device according to the invention by the features of the characterizing part of claim 1 and claim 8 .

Accordingly, the invention relates to a device for adjusting a door, the door being connected to a wall or fixed panel element and comprising a bearing part which is connected to the wall or fixed panel element, a bearing lifter being arranged in the bearing part, the at least one Floor space 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 arranged on a door lifter complementary floor space. Advantageously, it is provided that the bearing lifter has beveled, seesaw-like surfaces on the side opposite the placement area and a tensioner is provided as a force transmitter, which is connected to the bearing lifter, the tensioner being movably mounted in the bearing part and an adjustment means in the bearing part for adjustment is provided, which can be designed as an adjusting screw. An adjusting screw and a locking screw are advantageously provided for this purpose in the bearing part.

The stepless and backlash-free adjustment of a door leaf with a lifting and lowering mechanism via a pre-tensioned rocker has the following advantages over the previously known adjustments: With just one screw, a simple and backlash-free angle adjustment of a door leaf with a lifting and lowering mechanism is made possible via the pre-tensioned rocker. This means that even minimal angle changes can be made several times. The angle adjustments can be held 100% using the rocker.
According to a particular feature of the invention, the tensioner is designed as spring steel or as a compression spring. The bearing lifter can advantageously be moved axially via the adjusting screw, with the tensioner being tensioned and the angular position of the door being adjustable, with the adjustment of the door then being able to be secured via the locking screw 7 .

The invention relates to a device for a simple, backlash-free, stepless adjustment of a door leaf with a lifting and lowering mechanism via a so-called prestressed rocker. The invention can be used both in connection with a fixed panel part with a door or the door on a wall. The device can be installed in a direct wall connection to the door, in a fixed field connection to the door or in a fitting. The doors and fixed panels can of course be installed at different angles to each other. (Escape, at a 90° angle, etc.)
The parts of the device are in the in the 1 shown exploded view.

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

The assembly comprising the device is assembled in an untensioned position. Two beveled surfaces of the bearing lifter 2 are referred to as a rocker 2.1. The bearing lifter 2 with the rocker 2.1 (beveled surfaces) is mounted with a tensioner 3 (spring steel) in the bearing 1, with the surfaces of the bearing 1 opposite the beveled surfaces of the rocker 2.1 also being beveled. The tensioner 3 is firmly connected to the bearing jack. The tensioner 3 is pressed firmly into the bearing lifter 2 via a so-called press fit and is firmly seated there. This assembly is then placed in bearing part 1, where the tensioner is mounted in a form-fitting manner with slight play. In the bearing 1 the tensioner 3 is movably mounted (sliding). The door 13 is inclined or at an angle ( 3 ).

By turning the adjusting tool 6, the bearing lifter 2 is moved axially with the rocker 2.1 via the adjusting screw 4 and is in the neutral control position ( 4 - delivery status). The tensioner 3 is biased.

The bearing lifter 2 can be moved further in the axial direction by turning the adjusting screw 4 further with the aid of the adjusting tool 6 . This further changes the neutral position of the door leaf 13 (lifting curve below) ( 5 ).

The force of the pretensioned 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 dimension of the construction. In shower cubicle construction, +/-10° is usually sufficient for adjustability. After the door leaf 13 has been adjusted, it is secured by the locking screw 7 and the adjustment opening 1.3 around bearing 1 is covered by the cover 8. 6 shows a vertical section of the device and the door 13 with the fixed panel or wall profile. The door 13 rises vertically above 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.

As a tensioner, all means can be used as a force transmitter with which a pretension can be generated. How from the 7 - 9 As can be seen, the preload can also be generated using a compression spring instead of spring steel.
