Description

DESCRIPTION

Wall mounting for a shower bar

The invention relates to a wall fixing for a shower bar of a shower system according to the preamble of claim 1.

Such a shower bar is generally mounted vertically on two wall-mounting brackets on an installation wall, specifically spaced horizontally from the installation wall in the depth direction. The shower bar may have a hole or other connecting contour for attachment to the corresponding bracket. The shower bar can be attached to the respective bracket in a predefined longitudinal position using the connecting contour.

A generic wall mounting bracket can be configured in at least two parts with a wall bracket that can be mounted on the installation wall and with a support base body to which the shower bar can be fixed.

The installation wall may have wall protrusions, such as those generated at a transition from a tiled to an untiled wall area. For example, a lower wall fixing bracket can be mounted on the tiled wall section, while the upper wall fixing bracket is installed on the untiled wall area. The wall offset between the tiled and untiled areas can be compensated for with special compensation discs. These can be placed underneath the respective wall bracket of the wall fixing bracket. Problems arise when multiple compensation discs are used or stacked. In this case, the supplied standard screws may no longer be long enough to screw into the installation wall. The result could be failure under load. If an end customer only notices the annoying wall misalignment during the installation attempt, they are forced to order or purchase compensation discs later. This, in turn, increases the installation effort for the installer or end customer.

Document US 2019/0211537 A discloses a shower bar system with a wall fixing, the wall fixing being connected to the shower bar by means of a T-shaped connecting piece.

Document CN 205804510 U discloses a wall fixing that is attached to a multi-piece shower bar with the aid of a T-shaped fitting piece.

Document EN 2601 059 B discloses as the closest prior art a shower bar with a longitudinally adjustable wall divider,

a clamping screw is provided for locking on the wall separator.

The object of the invention is to provide a wall mounting for a shower bar that enables structurally simple mounting and reduces the mounting space of the shower bar on the installation wall.

The objective is solved by the features of claim 1. Preferred improvements of the invention are disclosed in the dependent claims.

According to claim 1, the wall mounting bracket has a depth locking device by means of which the support base body and the wall bracket can be telescopically adjusted relative to each other in the depth direction. This allows a suitable distance to be set between the shower bar and the installation wall and, if necessary, a displacement of the wall can be compensated for.

In one technical embodiment, the support base body is a hollow profile part, in particular of rectangular cross-section. The hollow profile part forms a telescopic guide in which the wall support is guided in an adjustable manner in the depth direction, preferably with little movement backlash. The end face of the hollow profile part facing the wall can be open. The open end face allows the wall support to be telescopically and adjustable into an installation space defined by the hollow profile part. The wall support can be in sliding contact with the inner sides of the hollow profile section to ensure smooth guidance.

The wall bracket is generally attached to the installation wall by means of a screw. In this case, the wall bracket may have a base part, preferably made of solid material, which can be clamped between the head of the fixing screw and the installation wall. At least one guide bar, which can be part of the aforementioned telescopic guide, protrudes from the base part of the wall bracket in the depth direction. The guide bar is guided in a guide channel of the base support body. The guide channel can, in turn, be configured in the installation space of the base support body. In one technical embodiment, the guide channel can be limited in an upward direction of the shower by the upper narrow side wall and a material rib in the installation space of the base support body.

In a specific embodiment, the wall mounting bracket can have a locking element that can be adjusted between an unlocked position and a locked position. In the unlocked position, the support base body and the wall bracket can be telescopically adjusted relative to one another. In contrast, in the locked position, the support base body and the wall bracket are secured to one another in the depth direction.

In a simple embodiment, the locking element can be a locking screw. This can be threadedly connected to an internal thread formed in the support base body. The locking screw can cooperate with a complementary wall support contour formed on the guide bar.

With this in mind, the locking screw can be adjusted to the locked position during a screwing operation in which the locking screw is held by the complementary contour of the wall bracket. Preferably, depressions are provided in the complementary contour of the wall bracket into which the locking screw can be drawn into the locked position. In a specific embodiment variant, the aforementioned wall bracket guide bar can be a toothed rack with profile teeth and with gaps between the teeth that form the aforementioned depressions.

With regard to a sufficiently stable support in terms of components, according to the invention, the support base body, which is designed as a rectangular hollow profile, has an additional material rib that connects the two opposite, flat side walls together. The material rib delimits the guide channel together with a narrow upper/lower side wall of the support base body.

In this case, the locking screw can be arranged in the narrow side wall, with the wall support guide bar being able to rest on the inner material rib in the locked position.

To further simplify assembly, the wall mount preferably has a total of two guide rods. When assembled, the first guide rod can extend into the guide channel of the support base body, while the second guide rod extends into the interior mounting space of the support base body without any function. In this case, the wall mount can be inserted into the support base body by rotating it 180°.

As an alternative to the previous embodiment, the depth locking device can also have a self-locking adjusting screw instead of a locking screw. By turning it, the wall bracket and the support base body can be telescopically adjusted relative to each other in the depth direction. The adjusting screw can be arranged with its screw head fixed in the mounting space of the support base body in the depth direction. This protects the adjusting screw from external mechanical influences and from view. The screw shank of the adjusting screw can be threaded onto an internal thread of the wall bracket. By turning the adjusting screw, it is screwed into the internal thread of the wall bracket or unscrewed, allowing the wall bracket to be telescopically and continuously adjusted relative to the support base body.

To ensure that the adjusting screw is guided correctly, the head of the adjusting screw is preferably positioned in the guide channel of the support base body. To hold the adjusting screw securely in position in the depth direction, a depth stop is preferably arranged on each side of the screw head. The two depth stops prevent the screw head from shifting in the depth direction. To simplify assembly/disassembly of the wall mounting bracket, it is preferred that at least one of the depth stops is designed as a removable locking screw. The removable locking screw can preferably be screwed into the narrow side wall of the support base body.

As mentioned above, the adjusting screw is screwed into or out of the internal thread of the wall bracket by means of a rotary drive. In one embodiment, turning the adjusting screw may only be possible in a disassembled state (not shown), in which the wall bracket is completely removed from the support base body. To separate the wall bracket from the support base body in this way, the locking screw, which acts as a depth stop, must be loosened. The wall bracket and the support base body can then be separated from each other so that tool access to the hexagonal profile of the adjusting screw is exposed.

Two embodiments of the invention are described below with reference to the attached figures.

They show:

Figure 1 is a side sectional view of a shower bar fixed to an installation wall;

Figures 2 and 3 in each case a wall mounting bracket in a sectional view and in a general perspective view;

Figures 4 to 6 in each case one of the components of the wall mounting bracket;

Figure 7 shows a wall mounting bracket according to the second embodiment in a view corresponding to Figure 2; and

Figures 8 to 10 show the components of the wall mounting bracket in Figure 7, in each case individually.

1 shows a shower bar 3 of a shower system (not shown), attached to an installation wall 1. The shower bar 3 extends in the vertical direction z and is attached to the installation wall 1 by means of two wall mounting brackets 5. In the installation position shown in accordance with FIG. 1, the installation wall 1 has a lower wall region 1a and an upper wall region 1b, which adjoin one another in a stepped manner and are offset relative to one another by a wall offset w in the depth direction x. The wall offset w can be compensated for by means of depth compensation devices 21 integrated in the two wall mounting brackets 5.

To configure the depth compensation device 21, each wall mounting bracket 5 is configured in two parts, namely with a wall bracket 7 mounted on the installation wall 1 and a support base body 9. The wall bracket 7 can be screwed into a hole drilled in the installation wall 1 by means of a fixing screw 13 with an anchor 15. In addition, the wall bracket 7 is inserted into the support base body 9 telescopically and adjustable in the depth direction x. In Figure 1, the upper wall bracket 7 protrudes from the support base body 9 with a projection Ax. The projection Ax is identical to the wall offset w, while the lower wall bracket 7 is inserted flush into the lower support base body 9 and does not protrude in the depth direction x. The projection Ax of the upper wall mounting bracket 5 thus compensates for the offset w of the installation wall 1.

In the figures, the support base body 9 is designed as a hollow profile part with a rectangular cross-section. The hollow profile part forms a telescopic guide in which the wall bracket 7 is guided in a telescopically adjustable manner in the depth direction x with little movement play. The support base body 9, designed as a hollow profile part, has narrow upper and lower side walls 23, 25, which are connected to one another via flat side walls 27. The support base body 9 delimits an inner mounting space 28 in which the aforementioned depth locking device 21 is arranged.

According to Figures 2 or 5, the wall bracket 7 has a base part 29 essentially made of solid material, through which the fixing screw 13 is guided. Two guide bars 31 project from the base part 29 in the depth direction x, which are designed as racks in Figures 2 or 5. In Figures 2 or 5, the upper guide bar 31 of the base part 29 is adjustably guided in a guide channel 33 of the support base body 9. In the vertical direction z, the guide channel 33 is delimited at the top by the upper narrow side wall 23 and, at the bottom, by a material rib 35 which extends between the two flat side walls 27 and braces the support base body 9. In Figure 2, the box-shaped support base body 9 is open at the end face closest to the wall. The wall bracket 7 protrudes through the open front side of the support base body 9 into the inner mounting space 28 of the support base body 9.

According to Figure 2, a threaded hole is formed in the upper narrow side wall 23, into which a locking screw 37 is screwed. The locking screw 37 acts as a locking element which fixes the wall bracket 7 and the support base body 9 in position in the depth direction x. Figure 2 shows the locking screw 37 in a screwed locking position V. In the locking position V, the locking screw 37 is brought with its screw tip into a form-fitting connection with the rack 31, the underside of the rack 31 resting stably on the material rib 35.

By unscrewing it, the locking screw 37 can be moved to its unlocked position E, not shown, in which the wall bracket 7 can be adjusted in the depth direction x relative to the support base body 9.

As can also be seen in FIGS. 2 and 4, the supporting base body 9 has a connecting contour 39 on its end face away from the wall for connecting the shower rod 3. An oblong hole 41 extending in the vertical direction z is formed in the connecting contour 39. A fixing screw 46 penetrates the oblong hole 41, which in FIG. 2 is removably screwed to the shower rod 3 with an intermediate element 40 inserted (FIG. 6). In the installed position (FIG. 2), the intermediate element 40 covers an end face of the guide channel 33 facing away from the wall.

Figure 7 shows a second embodiment of the wall mounting bracket 5. The depth locking device 21 does not have a locking screw 37, but rather a self-locking adjusting screw 43, which is aligned in the depth direction x. The adjusting screw 43 is inserted with its screw head 45 into the guide channel 33, i.e., into a stationary position in the depth direction x. A depth stop 47 and 49 are each arranged on both sides of the screw head 45 for stationary positioning. The depth stop 47, which faces the wall, is screwed into the lower, narrow side wall 25 of the support base body 9 as a removable locking screw, while the other depth stop 49 is integrally formed with the support base body 9 of the same material. The screw head 45 of the adjusting screw 43 has a hexagonal internal profile.

In Figure 7, the adjusting screw 43 is in threaded contact with an internal thread 51 of the wall bracket 7. By turning the self-locking adjusting screw 43, it is screwed into or unscrewed from the internal thread 51 of the wall bracket 7, resulting in a continuous telescopic adjustment of the wall bracket 7 with respect to the support base body 9.

In Figure 7, the adjusting screw 43 can only be turned in a disassembled state, not shown, in which the wall bracket 7 is completely disassembled from the support base body 9. To do this, the locking screw in Figure 7, which acts as a depth stop 47, must be loosened. The wall bracket 7 and the support base body 9 can then be separated from each other so that the tool access to the hexagonal profile of the adjusting screw 43 is exposed.
