Abstract

A wall bracket (14) for attaching a mounting frame for a sanitary fitting and a system for attaching a sanitary fitting to the wall bracket (14). By using a quick-release fastener (40), the adjustment of the wall bracket (14) is simplified and can be done without tools, without compromising the precision of the adjustment.

Description

[0001] The present invention relates to a wall bracket for fastening a sanitary fitting according to the preamble of claim 1 and a system for fastening a sanitary fitting according to the preamble of claim 7.

[0002] Sanitary fittings include bidets, shower trays, urinals, washbasins, and toilets. These sanitary fittings can be installed directly against a wall or floor of a building, but modern plumbing installations generally prefer a so-called pre-wall installation, which involves a supporting frame that is installed against a wall or floor of a building, to which the sanitary fitting is attached.

[0003] Wall brackets are used to attach the support frame to walls and floors. These must be adjusted to ensure the required clearance between the support frame and the wall or floor is maintained.

[0004] Systems consisting of support frames and wall brackets are used, such as those described in DE 10 2017 130 596 A1 (see there Fig. 8 ) are known.

[0005] It is already known from EP 4 039 897 A1 that the wall bracket has an anchor element with a fastening section for fastening the anchor element to a supporting structure and a fastening element with a fastening section for fastening a sanitary fitting, wherein the fastening element is arranged so as to be displaceable and fixable relative to the anchor element.

[0006] The usual procedure is to then position the support frame at the desired location in the room and attach the detached wall bracket to both the wall or floor and the support frame. The support frame is then aligned using horizontal and vertical alignment check devices to ensure it is level both horizontally and vertically. The wall bracket is then adjusted accordingly.

[0007] The disadvantage of this design is the relatively complex construction of the wall mount, which requires a rough adjustment first, followed by fine adjustment using a tool. Fine adjustment is achieved by twisting a threaded rod in a sleeve. This makes adjusting the wall mount and ultimately leveling the support frame difficult.

[0008] The object of the present invention is therefore to improve the adjustment of the wall mount. In particular, the adjustment of the wall mount should be quick and uncomplicated without compromising the precision of the adjustment.

[0009] This object is achieved with the wall mount according to the invention according to claim 1 and the system according to the invention according to claim 7. Advantageous further developments are specified in the dependent claims and in the following description together with the figures.

[0010] The inventors realized that this task can be solved in a surprising way and particularly easily if the wall bracket is designed in such a way that the movement and fixing can be carried out without tools, because this makes the adjustment very easy and quick.

[0011] The wall bracket according to the invention with an anchor element with a fastening section for fastening the anchor element to a supporting structure and a fastening element with a fastening section for fastening a sanitary fitting, wherein the fastening element is arranged so as to be displaceable and fixable relative to the anchor element, is characterized in that the wall bracket is designed to produce a releasable positive connection between the anchor element and the fastening element, wherein the wall bracket comprises a tensioning element for fixing or releasable the positive connection.

[0012] Within the context of the present invention, "fixing" the positive connection means that the positive connection exists and cannot be released without actuating the clamping element. "Making the positive connection releasable" within the context of the present invention means that the positive connection either no longer exists or can be released without actuating the clamping element. Preferably, the positive connection still exists even when made releasable, but can be released without actuating the clamping element.

[0013] In an advantageous further development, the fastening element is designed to be displaceable relative to the anchor element in a horizontal plane. This provides a horizontal displacement direction. This allows the distance of the sanitary fixture from the supporting structure, for example, a wall, to be adjusted very precisely.

[0014] In an advantageous development, the fastening element is designed to be pivotable relative to the anchor element, with the pivotability preferably occurring in a horizontal plane. This allows for non-parallelisms between the supporting structure, for example, a wall, and the sanitary fixture to be compensated for. Furthermore, sanitary fixtures can also be very easily and securely attached to rectangular, curved, or irregularly shaped wall corners and the like.

[0015] "Relative" in this context means that not only the first element can be moved or pivoted relative to the second element, but also the second element relative to the first element, or both elements can be moved or pivoted in space at the same time, whereby a displacement or pivoting relative to each other also occurs.

[0016] In an advantageous further development, the clamping element is designed as an eccentric clamping element. This allows for the locking or releasing of the positive locking mechanism to be particularly quick, easy, and safe.

[0017] In an advantageous further development, the clamping element is designed to be lockable. This allows the positive locking to be established particularly securely.

[0018] In an advantageous further development, the anchor element and the fastening element are provided with shaped surfaces that are designed to engage with one another, with the shaped surfaces preferably being designed as toothed profiles, in particular as rack profiles. This ensures particularly secure locking of the positive connection, and in addition, the displacement can be performed in a grid and thus very precisely. The grid spacing can be adjusted to a desired value by selecting the length of the tooth base.

[0019] In an advantageous further development, it is provided that in the releasable state of the form fit, one forming surface is prestressed relative to the other forming surface with respect to the normals of the forming surfaces, wherein the prestress is set such that the forming surfaces engage with each other in the releasable state of the form fit, but deflection in the direction of the normal of one forming surface relative to the other forming surface against the prestress is possible such that a displacement of the forming surfaces perpendicular to the normals is possible, wherein preferably a grid-like displacement of the forming surfaces perpendicular to the normals is possible. This enables very sensitive adjustment because the user glides from one fixing position to the next when displacing the forming surfaces relative to each other and can therefore monitor the alignment to be adjusted very precisely.

[0020] In an advantageous further development, the tooth profiles are designed such that, when in engagement with one another, they can be displaced transversely relative to one another unless pressed against one another with a specific pressure. The tooth flanks of the tooth profiles preferably have an angle in the range of 30° to 80°, preferably an angle in the range of 40° to 70°, in particular in the range of 50° to 60°, relative to the normal of the forming surfaces. This allows for particularly simple and sensitive adjustment.

[0021] In an advantageous development, one of the anchor element and fastening element has an elongated hole through which a through-hole of the other of the fastening element and anchor element passes, with the through-hole preferably being designed as a pin. This makes the wall mount particularly simple and compact.

[0022] In an advantageous development, one of the anchor element and fastening element comprises a movable clamping element that serves to create the positive connection. This also makes the wall mount particularly simple and compact.

[0023] In an advantageous development, one of the anchor element and fastening element has a guide for the other of the fastening element and anchor element. This also makes the wall mount particularly simple and compact.

[0024] In an advantageous development, a movable intermediate element is provided between the tensioning element and the clamping element, with a spring element preferably being arranged between the clamping element and the intermediate element. In particular, it is provided that the clamping element, the spring element, the intermediate element, and the tensioning element are arranged on the through-passage part. This allows for the bracing and pre-tensioning functions to be implemented particularly easily.

[0025] Independent protection is claimed for the system according to the invention for fastening a sanitary fitting to a supporting structure, comprising the wall bracket according to the invention and a supporting frame for arranging the sanitary fitting thereon.

[0026] In an advantageous further development, for which independent protection is claimed even independently of the combination of the support frame with the wall bracket according to the invention within the framework of the system according to the invention, it is provided that the support frame comprises a means for checking the horizontal and / or vertical alignment of the support frame in a room, wherein the means for checking preferably comprises a spirit level, an electronic inclination sensor and / or a laser emitter. In particular, the means for checking comprise the vial of a spirit level. This allows the alignment of the support frame to be carried out very quickly and without further external aids because the support frame itself can indicate its exact alignment. Furthermore, this allows a subsequent change in the position of the support frame to be determined very precisely.

[0027] In an advantageous development, the support frame comprises at least one vertical support and at least one horizontal support, preferably two vertical supports arranged at a distance from one another and two horizontal supports arranged at a distance from one another, wherein the vertical supports and the horizontal supports are connected to one another, in particular in a frame-like manner. The support frame is then particularly stable. Preferably, both the vertical supports and the horizontal supports are aligned parallel to one another.

[0028] In an advantageous development, it is provided that the means for checking the horizontal and / or vertical alignment of the support frame is arranged on the vertical support and / or the horizontal support. The alignment of the support frame can then be determined very precisely and reproducibly. Preferably, the means for checking the horizontal and / or vertical alignment of the support frame is inserted into the vertical support and / or the horizontal support. This reduces the risk of damage to the means for checking the horizontal and / or vertical alignment. A means for checking the horizontal and / or vertical alignment can be arranged on a vertical support, or a means for checking the horizontal and / or vertical alignment can be arranged on a horizontal support.However, a means for checking the horizontal and / or vertical alignment could also be arranged on both the vertical beam and the horizontal beam.

[0029] In an advantageous development, an acceleration sensor is arranged on the support frame. This also allows subsequent changes in the position of the support frame to be determined very precisely.

[0030] In an advantageous development, it is provided that means for monitoring the room air are arranged on the support frame, wherein the means for monitoring the room air preferably comprise at least one of the following elements: temperature sensor, humidity sensor, spore sensor, dust sensor, smoke sensor, and a sensor for analyzing the presence of certain chemical substances. This allows further monitoring of the pre-wall installation to be carried out with the help of the support frame. For example, it can be checked whether moisture is accumulating behind the pre-wall installation over time or whether mold is forming. This allows for rapid action to remedy the situation.

[0031] In an advantageous development, the system is designed to emit a signal when at least one state variable from the field of support frame orientation and room air properties changes critically. The signal is preferably emitted electrically or electronically, in particular wired or wirelessly. This allows for continuous monitoring of the pre-wall installation for critical conditions and for building and supporting structure monitoring. This signaling function of the system can be provided on the support frame.

[0032] The features and further advantages of the present invention will become clear below from the description of a preferred embodiment in conjunction with the figures. These show, purely schematically: Fig. 1 the system according to the invention comprising the support frame according to the invention and the wall bracket according to the invention in a first preferred application in a perspective view and with an enlarged detail of the detail A, Fig. 2 a section of the system according to Fig. 1 in a perspective view, Fig. 3 the wall bracket according to the invention in an exploded view, Fig. 4 the wall bracket according to the invention according to Fig. 2 in a sectional view, Fig. 4b the wall bracket according to the invention according to Fig. 2 in a sectional view of the enlarged detail B, Fig. 5a-c the fastening element of the wall bracket according to the invention according to Fig. 2 different views, Fig. 6a-c the clamping element of the wall bracket according to the invention according to Fig. 2 different views, Fig. 7a the wall bracket according to the invention according to Fig. 2 in a first operating state, Fig. 7b the wall bracket according to the invention according to Fig. 2 in a second operating state, Fig. 8Detail view of the toothing of the wall bracket according to the invention Fig. 2 , Fig. 9 the system according to the invention comprising the support frame according to the invention and the wall bracket according to the invention in a second preferred application in a first detailed view from above and Fig. 10 the system according to the invention according to Fig. 9 in a second detailed view from the side.

[0033] In the Fig. 1 bis 8 the system 10 according to the invention is shown in a first preferred application, while the Fig. 9 and 10 show a second preferred application.

[0034] In Fig. 1 the system 10 according to the invention is shown in a perspective view, wherein an enlarged detail of detail A is also shown.

[0035] It can be seen that the system 10 comprises a support frame 12 according to the invention, on which the wall bracket 14 according to the invention is arranged. This wall bracket 14 serves to connect the support frame 12 to a wall 16 of a room (not shown in detail), as in Fig. 2 can be seen.

[0036] Elements of a sanitary fitting, namely in the present case a toilet (not shown), are already shown on the support frame 12, namely, among other things, a cistern 18 and elements for water guidance 20.

[0037] The support frame 12 has telescopic feet 22 for fastening the support frame 12 to a floor 24 (cf. Fig. 1 ) and connecting means 26 for the firm connection of the supporting frame 12 with the wall bracket 14 (cf. Fig. 2 ).

[0038] As can be seen, the support frame 12 is formed from two vertical supports 27 arranged at a distance from each other in parallel and three horizontal supports 28 arranged at a distance from each other in parallel, which are connected to each other in a frame-like manner, whereby the support frame 12 is very stable.

[0039] In this case, a spirit level 30 is located on the upper horizontal support 28a of the support frame 12, which is firmly connected to the horizontal support 28a in such a way that it indicates the horizontally and vertically leveled alignment of the support frame 12 or the non-leveled alignment of the support frame 12 (cf. the enlargement of detail A in Fig. 1 ).

[0040] The wall bracket 14 according to the invention is in the Figuren 3 bis 7 shown in detail.

[0041] It can be seen that the wall bracket 14 has an anchor element 32 with a fastening section 34 for fastening the anchor element 32 to a supporting structure (here in the form of the wall 16) and a fastening element 36 with a fastening section 38 for fastening the supporting frame 12 for the sanitary fitting (not shown).

[0042] Furthermore, it can be seen that the fastening element 36 is arranged so as to be displaceable and fixable relative to the anchor element 32, wherein a tensioning element 40 is provided in order to produce a releasable positive connection between the anchor element 32 and the fastening element 36.

[0043] More specifically, the anchor element 32 has a horizontally extending section 42 in which a depression 44 with an opening 46 is arranged. The depression 44 has a hexagonal cross-section, and its dimensions are adapted such that the drive 48 of a pin 50 is positively received therein and fixed in a non-rotatable manner. Thus, the pin 50 extends perpendicular to the direction of extension of the horizontally extending section 42, and the pin 50 thus extends vertically.

[0044] The pin 50 has at its end 52 opposite the drive 48 a through hole 54 for a bearing pin 56, which forms the pivot bearing for an eccentrically designed pivot lever 58.

[0045] The pin 50 passes through the fastening element 36 and between the fastening element 36 and the clamping lever 58 are a clamping element 60, a spiral spring 62 (in Fig. 3 not shown for the sake of clarity, but only in Fig. 4 and Fig. 7 ), and a guide disc 64 are arranged.

[0046] The fastening element 36 has a horizontally extending section 66 in which an elongated hole 68 is formed in a depression 70. On the underside of the elongated hole 68, there is a rack-like toothing 72 on both sides of the elongated hole 68. The depression 70 has on its underside 74 parallel wall sections 76, as best shown in Fig. 5a can be seen.

[0047] The clamping element 60 has, as in Fig. 6 As can best be seen, it has a base 78 on which there are upwardly extending jaws 80 on both sides. The inner contour of these jaws 80 is designed such that they can slide snugly against the wall sections 76 of the fastening element 36.

[0048] On the upper side 82 of the base 78, there is a continuous, rack-like toothing 84, which is interrupted only by a continuous opening 86 in the base 78. This opening 86 serves to accommodate the pin 50.

[0049] On the underside 88 of the base 78 there are stiffening ribs 90 and a widening 92 with a shoulder 94 in relation to the opening 86.

[0050] The widening 92 is dimensioned such that the spiral spring 62 is received therein, wherein the spiral spring 62 is supported on the one hand on the shoulder 94 and on the other hand on the guide disk 62 (cf. Fig. 4b ).

[0051] The teeth 72, 84 are matched to one another in such a way that when the upper side 82 of the clamping element 60 is in direct contact with the underside 74 of the depression 70 of the fastening element 36, they result in a positive connection which - when the two surfaces 82, 74 are pressed against one another - prevents the clamping element 60 from being displaced relative to the fastening element 36 in the displacement direction S (cf. Fig. 4 and 7 ).

[0052] The teeth 96, 98 of the toothings 72, 84 are designed such that they allow the clamping element 60 to retreat against the spring 62 and thus against the vertical V when a force is exerted on the clamping element 60 in the displacement direction S, which runs horizontally, relative to the fastening element 36. For this purpose, the teeth 96, 98 have, for example, an angle α with respect to the normal n of the surfaces 74, 82 in the range 50° ≤ α ≤ 60°. The toothings 72, 84 can then slide particularly easily against one another if the surfaces 74, 82 are not pressed against one another, and the positive connection between the toothings 72, 84 is nevertheless very secure if the surfaces 74, 82 are pressed against one another (cf. Fig. 8 ).

[0053] The eccentricity of the clamping lever 58 is caused by the fact that the first contact surface 100, as a tangent, is located closer to the opening 104 for the bearing pin 56 in contrast to the second contact surface 102 (cf. Fig. 3 ). Curve 106 represents a ramp between these two distances.

[0054] These surfaces, i.e. the first contact surface 100, the curve 106 and the second contact surface 102, slide on the guide disc 64 when the clamping lever 58 is pivoted, whereby the guide disc is moved up or down.

[0055] The distance between the second contact surface 102 and the opening 104 is dimensioned such that when the second contact surface 102 is in contact, the guide disc 64 is pressed directly onto the underside 88 of the clamping element 60 and the surfaces 74, 82 are thereby pressed against one another, whereby a positive connection is established between the toothings 72, 84 (cf. Fig. 7a ).

[0056] The distance between the first contact surface 100 and the opening 104 is dimensioned such that when the first contact surface 100 is in contact, the guide disc 64 is not pressed directly onto the underside 88 of the clamping element 60. However, the spiral spring 62 presses the surfaces 74, 82 together, which also creates a positive connection between the toothings 72, 84 (see. Fig. 7b ).

[0057] To produce the positive connection, the recess 44 of the anchor element 32, which rests against the recess 70 of the fastening element 36, forms an abutment with the drive 48 of the pin 50 to the clamping lever 58.

[0058] A positive connection thus always exists between the toothings 72, 84: Either the two toothings 72, 84 are pressed together by the clamping lever 58, thus creating the positive connection, or the two toothings 72, 84 are pressed together by the spiral spring 62, thus creating the positive connection. However, in the first case of pressing, this is a fixed positive connection, and in the second case of pressing, it is a releasable positive connection.

[0059] The coil spring 62 creates such a preload that a positive connection is always established even when the clamping element 60 is displaced relative to the fastening element 36. As a result, a user who displaces the clamping element 60 relative to the fastening element 36 feels a ratcheted sliding action, which is caused by the successive engagement and disengagement of the positive connection between the teeth 72, 84 under the preload of the coil spring 62.

[0060] By overcoming the curve 106, the clamping lever 58 is released from the Fig. 7a shown fixed position into the Fig. 7b The second contact surface 102 and the first contact surface 100 each form a safety feature, so that the clamping lever 58 will not rotate about the bearing pin 56 without active pivoting by a user. Therefore, there are locking mechanisms for the respective position of the clamping lever 58.

[0061] The fastening element 36 is a plastic injection-molded part, as are the clamping element 60 and the tensioning lever 58. In contrast, the anchor element 32, the pin 50, the coil spring 62, and the guide disc 64 are made of metal. To stiffen the anchor element 32, jaws 110 are arranged in the angles 108 between the horizontally extending section 42 and the fastening section 34 (see Fig. Fig. 3 ).

[0062] There could be guide means (not shown) whereby the anchor element 32 is secured against rotation in the displacement direction S relative to the fastening element 36. This guide could, for example, consist of a grip around the anchor element 32 similar to the jaws 110. On the other hand, the shape of the depression 44 could also be designed such that it slides against the depression 70 of the fastening element 36 over a certain section, thus providing the anti-rotation protection.

[0063] In the illustrated embodiment, no such guide means exist, which is why the fastening element 36 can be pivoted in a horizontal plane relative to the anchor element 32. This allows for compensation for non-parallelisms between the support frame 12 and the supporting structure 16.

[0064] The fastening element 36 has locking elements 112 (cf. Fig. 3 ) which are connected to corresponding locking elements 114 of the support frame 12, which are part of the connecting means 26 (cf. Fig. 2 ), whereby the wall bracket 14 can be fixed to the support frame.

[0065] The use of the system 10 according to the invention with the aid of the support frame 12 according to the invention and the wall bracket 14 according to the invention according to the first preferred application, in which the support frame 12 and the wall (the supporting structure) 16 run parallel to each other, will now be described:

[0066] First, the support frame 12 is provided with the two wall brackets 14, whereby the locking elements 112 are clipped into the locking elements 114.

[0067] Then, the support frame 12 is placed at the location in the room where it is to be installed, and the feet 22 are telescoped to the required length. There, the feet 22 are screwed to the floor 24, but not completely tightened. Appropriate holes and, if necessary, dowels must be drilled into the floor 24.

[0068] The clamping levers 58 of the two wall brackets 14 are then pivoted downwards (cf. Fig. 7b ), whereby the clamping element 60 on the fastening element 36 is released, allowing the anchor element 32 and fastening element 36 to be freely displaced relative to one another in the direction of displacement S. These two elements 32, 36 are adjusted relative to one another such that the fastening sections 34 of the anchor elements 32 each bear against the wall 16, with the supporting frame being approximately plumb. The fastening sections 34 of the anchor elements 32 are then firmly screwed to the wall 16, with corresponding holes and, if necessary, dowels being drilled into the wall 16.

[0069] Next, the two wall brackets are adjusted so that the spirit level 30 indicates the exact leveling of the support frame 12 in both the vertical and horizontal directions. The locking sliding between the teeth 72, 84 allows for particularly precise adjustment of the wall brackets 14.

[0070] When the wall brackets 14 are adjusted so that the support frame 12 is exactly aligned, the clamping levers 58 are moved into the Fig. 7a shown position, whereby the positive connection between the teeth 72, 84 is fixed and thus the position of the fastening element 36 to the anchor element 32 is fixed and secured.

[0071] Finally, the screw connections of the feet 22 are fixed to the floor and then the elements 18, 20 of the sanitary fitting, a pre-wall (not shown) or the sanitary fitting (not shown) itself can be arranged on the support frame 12.

[0072] According to the second preferred application of the system 10 according to the invention, which is shown in the Fig. 9 and 10 As shown in detailed views, there is a supporting structure or wall 116 that has two wall sections 118, 120 that form a right angle between them. This is therefore a wall corner 122.

[0073] Here, the two anchor elements 32 are each pivoted with their longitudinal axes La relative to the longitudinal axes Lb of the fastening elements 36 in a horizontal plane H by the angle β, whereby this angle β = 45°.

[0074] Because the anchor element 32 can still be displaced relative to the fastening element 36 in the horizontal displacement direction S, an optimal adjustment of the installation of the support frame 12 and the sanitary fitting (not shown) arranged thereon with respect to the wall corner 122 can be achieved.

[0075] There is no locking mechanism for the pivotability β of the anchor elements 32 relative to the respective fastening elements 36. However, this is not even necessary because the pivot angles β are automatically determined by the fixation of the anchor elements 32 in the wall corner 122 and the fixation of the fastening elements 36 on the support frame 12.

[0076] The installation of the wall bracket 14 is carried out in principle in the same way as in the first preferred application according to the Fig. 1 bis 8 . Here, only the pivot angle β is additionally set in advance and then, when both the pivot angle β and the displacement between the anchor elements 32 relative to the respective fastening elements 36 have been carried out, the tensioning element 40 is locked so that the anchor elements 32 are locked relative to the respective fastening elements 36.

[0077] In the event that the pivotability β is to be locked, for example if only one wall bracket is to be used or can be used, this could be done, for example, by providing a toothing (not shown) on the recess 70 and, at the same time, an opposing toothing on the lower outer side of the recess 44. If at least one of the recesses 44, 70 is conical and the other recess 70, 44 is, for example, conical in parallel (not shown), then these two toothings can be brought into engagement, at least in some areas, by means of the clamping element 40, which would lock the pivotability β. Instead of toothing, the recess 70 could also be smooth and the lower outer surface of the recess 44 could be a conical polygon.Then a locking could be ensured at least for some angular orientations β (depending on the number of faces of the polygon).

[0078] If instead of the spirit level 30 (in Fig. 9 If (not shown) electrical or electronic means for checking the horizontal and / or vertical alignment of the support frame exist, for example an electronic inclination sensor or a laser emitter, wherein the laser emitter would be combined with a light detector which determines an angular deviation of the laser beam, then the adjustment can be carried out even more precisely and in particular can also be processed electrically or electronically.

[0079] Subsequent structural or supporting structure monitoring can then also be carried out, making it easy to detect subsequent changes to the building or supporting structure. An acceleration sensor can also be used in this context.

[0080] In addition, means for monitoring the indoor air quality (not shown) can be arranged on the support frame 12, wherein the means for monitoring the indoor air quality preferably comprise at least one of the following elements: temperature sensor, humidity sensor, spore sensor, dust sensor, smoke sensor, and sensor for analyzing the presence of certain chemical substances. Thus, with the aid of the support frame 12, further monitoring of the created pre-wall installation (not shown) can be carried out. For example, it can be checked whether moisture is accumulating behind the pre-wall installation over time or whether mold is forming. This allows for rapid action to remedy the situation.

[0081] Furthermore, the system 10 can be configured to emit a signal when at least one state variable from the field of orientation of the support frame 12 and the properties of the room air changes critically, with the signal preferably being emitted electrically or electronically, in particular wired or wirelessly. This allows for continuous monitoring of the created pre-wall installation for critical conditions and, in principle, for building and supporting structure monitoring.

[0082] Although the present invention has been described using the example of a concealed toilet, it is not limited to this. Other sanitary fittings, such as bidets, washbasins, and shower trays, can also be installed quickly and easily.

[0083] From the above illustration, it has become clear that the present invention significantly improves the adjustment of the wall bracket for attaching a piece of sanitary equipment. The adjustment of the wall bracket is quick and uncomplicated and can be carried out without tools, without compromising the precision of the adjustment. In conjunction with the support frame according to the invention, which has means for checking the horizontal and / or vertical alignment of the support frame, the installation of the support frame on a supporting structure can be carried out very quickly and easily. The pre-wall installation created thereby can be further improved if subsequent building or supporting structure monitoring is enabled by the means for checking the horizontal and / or vertical alignment, an acceleration sensor and / or means for room air monitoring, which would also be arranged on the support frame.
