Description

The present invention relates to a wallpapering brush, a bag for the wallpapering brush and a wallpapering set.

Wallpapering brushes are from the practice as well as the DE-U-295 03 046 known and find a variety of applications in professional and hobby. Wallpapering brushes, which also so-called wallpaper mops are expected, are used in wallpapering usually for pressing or smoothing a wallpapered with wallpaper wallpapering against or on a designated background. For this purpose, the wallpaper web is previously pasted, folded, attached to one end at a predetermined location on the ground, unfolded piecewise and painted using the wallpapering brush against the ground. The tasks to be performed prior to the use of the wallpapering brush, such as pasting, folding and piecing, typically require working with both hands, so that the wallpapering brush can only be grasped after setting. However, in order not to have to get the wallpapering brush for their use, a user likes to jam the wallpaper brush to save time under his arm or between his legs to have them at hand at all times. However, the wallpaper brush is a hindrance during the previous steps. When working on a ladder or scaffold, pinching the wallpaper brush can also be very dangerous. This is the case in particular when wallpapering in the overhead area, such as in upper wall sections or in the ceiling area.

In addition, in the case of known wallpapering brushes, there are frequently handling problems, in particular the grip, which also typically changes when wallpapering due to the effects of moisture. The currently known wallpaper wiper and brushes are usually made of solid wood. As a result, they have a relatively high weight, which can be increased by the water absorption during use. Due to the high weight and the unwieldiness chronic complaints in the wrist (for example epicondylitis) in the painting trade are not uncommon. In addition, the current external forms of wallpapering brushes often prevent effective working methods.

In view of the above, the present invention proposes a wallpapering brush according to claim 1.

According to one embodiment, the wallpaper brush comprises a brush shoe comprising a first end, a second end opposite the first end, and a handle portion having a smaller minimum distance from the first end than the second end. This allows safe handling of the wallpapering brush with one hand. In addition, the wallpapering brush comprises a brush part connected to the brush shoe on the underside thereof, the second end having a small extent in a normal direction of the underside than the first end. Typically, the brush shoe tapers toward the second end at least near the second end. For example, an expansion of the brush shoe in the normal direction of the underside may decrease with increasing distance from the grip part. As a result, hard-to-reach areas of applied wallpaper in corners and edges or behind radiators or heating pipes can be processed easily with areas of the brush shoe at or near the second end. Due to the tapered shape of the brush shoe, the wallpapering brush can also be stowed in side pockets or customs pockets of, for example, painter's work pants. This can increase both work efficiency and safety.

The brush part can be fixed but also releasably connected to the brush shoe. With a releasable connection, the brush parts can be easily changed, e.g. if the brushes have aged after prolonged use or if the brush type is to be adapted to the wallpaper. As a result, however, the cleaning of the wallpapering brush can be facilitated.

According to a further development, the bristles of the brush part are not aligned at least on average in the normal direction of the underside. Typically, the bristles form an acute angle with the underside at least on average, the z. B. may be in a range of about 35 ° to 75 °. This further facilitates the editing of hard-to-reach areas of the applied wallpaper.

According to yet another embodiment, the handle has an ergonomically designed area for one-handed touch, which forms an acute angle with the bottom. Typically, the acute angle ranges from about 15 ° to about 25 °. The angled, wrist-adapted handle simplifies the whole Handling the wallpapering brush considerably. As a result, loads on the user's hand, wrist and arm and thus risks of chronic discomfort, in particular of the wrist, are substantially reduced.

According to a further development, the ergonomically formed area is provided with a water-repellent coating, e.g. with a nubby, water-repellent rubber coating. This allows a secure grip even with wet palms, so that the force required for the movement of the brush, for example, when pressing the wallpaper significantly reduced. This allows a particularly wrist-friendly operation. In addition, the ergonomically formed area can be better cleaned due to the coating, e.g. of wallpaper paste residues.

According to a further development, at least the brush shoe is made of a plastic, e.g. a shell-like plastic housing. As a result, the wallpapering brush is relatively light, which further reduces the burden on the user. In addition, the typically smooth plastic surfaces are easier to clean.

According to one embodiment, a bag for accommodating a wallpapering brush comprises a housing which is substantially rectangular in plan view and has an opening which extends in a plan view as far as a first end of the housing. If the wallpaper brush is not needed, it can easily be stowed in the bag. Typically, the housing tapers in a cross-section in a direction away from the opening direction. As a result, the bag is well adapted to the shape of a wallpapering brush with tapered brush shoe.

According to a development, a holder is attached to a hinge on one side of the housing. This allows a secure and flexible attachment of the bag to the work clothes of a painter, so that the temporary unneeded wallpaper brush can be stowed easily and reliably. As a result, both the work efficiency and the work safety can be increased.

Typically, the bag is made of a plastic. The bag is relatively light and can also be easily cleaned.

According to yet another embodiment, a holder for a Nahtroller is attached to the underside of the housing. This allows easy access to the Nahtroller or a simple change of Nahtroller and wallpapering brush when wallpapering. As a result, the work efficiency and safety can be further increased.

According to one embodiment, a decorating set comprises a wallpapering brush and a pocket for receiving the wallpapering brush. The wallpaper brush comprises a brush shoe having a first end, and a second end opposite the first end, and a handle portion having a smaller minimum distance from the first end than the second end. In addition, the wallpapering brush comprises a brush part connected to the brush shoe on the underside thereof, the second end having a small extent in a normal direction of the underside than the first end. This allows safe handling of the wallpapering brush with one hand. The pocket includes a generally rectangular housing in a plan view with an opening extending in plan view to a first end of the housing, typically the housing is tapered in a cross section in a direction away from the opening. If the wallpaper brush is not needed, it can be safely stowed in the bag. This can increase both work efficiency and safety.

The term "wallpapering brush", as used herein, is intended in particular to describe a brush, with the help of a pasted wallpaper can be pressed while wallpapering on the wall, with even pressure when wiping with the wallpapering brush on the wallpaper air bubbles between the wall and wallpaper can be pressed out. The terms "wallpapering brush" and "wallpapering wiper" are used interchangeably.

Fig. 1 2 shows a schematic side view of a wallpapering brush 10. The wallpapering brush 10 has a brush shoe 4, which extends from a first end 1 to a second end 2 opposite the first end 1. In addition, the brush shoe 4 comprises a grip part 3 which has a smaller minimum distance d from the first end 1 than the second end 2. In the exemplary embodiment of FIG. 1 extends the handle part 3 to the first end 1. This allows safe handling of the wallpapering brush with one hand. In addition, the distance d is typically greater than about half the distance between the first end 1 and the second end 2.

In the in FIG. 1 However, the brush shoe 4 consists of a base body 4a and a handle part 3 fastened thereto. The brush shoe and grip part can, however, also merge seamlessly into one another, in particular if they consist of a material. In addition, the wallpaper brush 10 has a connected to the brush shoe on the underside 5 brush part. 6

The second end 2 of the brush shoe 4 has a small extent h in a normal direction of the underside 5 than the first end 1. Typically, the brush shoe 4 tapers towards the second end 2 at least in the vicinity of the second end 2. Thus, the expansion h of the brush shoe 4 in the normal direction of the underside 5 can decrease with increasing distance d ₁ from the grip part 3. This can be hard as well accessible areas of applied wallpaper in corners and edges or behind radiators or heating pipes are easily edited with areas of the brush part 6 at or near the second end 2 of the brush shoe 4. Due to the tapered shape of the brush shoe 4, the wallpapering brush 10 can also be stowed in pockets of workwear. As a result, both the work efficiency and the work safety can be increased.

The brush part 6 may be fixed or detachable, e.g. can be inserted or latched to be connected to the brush shoe 4. In a releasable connection, the brush parts 6 can be easily changed. Thus, aged brushes can be easily replaced after prolonged use and also the brush type can be adapted to the wallpaper. In addition, the cleaning of the wallpaper brush 10 can be facilitated so.

According to a further development, the bristles 7 of the brush part 6 are not aligned in the normal direction of the underside 5, at least on average. Typically, all or at least a majority of the bristles 7 with the underside 5 in the unloaded state form, at least on average, an acute angle .alpha. in a range of about 35 ° to 80 °, e.g. can be at about 40 °. In this case, the bristles 7 are rotated in a clockwise direction relative to the normal direction of the bottom 5 in a corresponding range of about 15 ° to 55 °. This makes it easier to work on hard-to-reach areas of the applied wallpaper. The pointed protruding or bug-like shape of the bundle of bristles 7 at the second end 2 serves as an extension compared to conventional wallpapering brushes.

Due to the typically relatively short and obliquely fitted bristles 7 reduces the risk of lateral breakage of the bristles 7 when pressed. Thus, the force required when pressing the wallpaper with the wallpapering brush 10. For example, the bristles 7 may have a length in a range of 2 cm to 4 cm and thus be about half as long as in conventional wallpaper brushes.

Fig. 2 shows a schematic side view of a wallpaper brush 20. The wallpaper brush 20 is similar to that with reference to FIG. 1 explained wallpapering brush 10 constructed. However, the grip part 3 of the wallpapering brush 20 has an ergonomically designed area 31 for one-handed grip, which with the underside has an acute angle γ in a region of forms about 15 ° to about 25 °. During the wallpapering with the decorating brush 20, the angle between the forearm and the metacarpals can be kept at about 120 °, which corresponds to an ergonomic wrist position. As a result of the ergonomically designed region 31, the burden on the hand, wrist and arm of the user and thus risks of chronic complaints, in particular of the wrist, are substantially reduced. The handle is typically ergonomically adapted for both left and right-handers.

Typically, the ergonomically formed region 31 is coated with a water-repellent coating, for example with a dimpled, water-repellent soft rubber coating. The height of the individual typically cylindrical knobs (not shown in FIG FIG. 2 ) can be about 2 - 4 mm. When enclosing the handle part 3 with the working hand, the soft knobs give way and thus the palm optimally adapted to the handle. Thus, a more stable gripping is ensured, which reduces slippage in moisture inside the handle. This allows a secure grip even with wet palms, so that the force required for the movement of the brush, for example, when pressing the wallpaper significantly reduced. This allows a particularly wrist-friendly operation. In addition, the ergonomically formed region 31 can be cleaned better due to the coating, for example of wallpaper paste residues.

Fig. 3 shows a schematic side view of a decorating brush 30. The wallpapering brush 30 is similar to that with reference to FIG. 2 explained decorating brush 20 and also has an ergonomically formed portion 31 of the handle part 3. However, the ergonomically formed region 31 is bulbous. This allows an even better grip when enclosing the ergonomically designed area 31 with the working hand.

Typically, the brush shoe 4, including the handle portion, is made of a plastic, e.g. a shell-like plastic housing. As a result, the wallpapering brush 30 is very light, whereby the burden of the user can be further reduced. In addition, the typically smooth plastic surfaces of the brush shoe 4 can be easily cleaned.

In addition, the brush shoe 4 may be made narrow in the plan, resulting in a saving of material and a further reduction in weight of the wallpapering brush 30 and thus a wrist and forearm area even better gentle working allows.

According to one embodiment, the obliquely fitted bristles 7 are shorter towards the first end 1 than the obliquely fitted bristles 7 at the second end 2. Accordingly, the support surface 15 of the bristles 7 may be slightly inclined relative to the underside 5 of the brush shoe, e.g. in a range of about 2 ° to about 10 °. As a result, a more effective power transmission to the wallpaper and thus an even better hand and forearm-friendly operation is possible.

Fig. 4 FIG. 12 shows a schematic side view of a pocket 50 with the wallpapering brush 30 accommodated therein. A schematic plan view of the pocket 50 is shown in FIG FIG. 5 shown. The pocket 50 has a substantially rectangular in plan view of the housing 51 with a typically oval opening 53 for receiving the wallpaper brush 10. In the side view, the opening 53 is disposed in an upper region of the housing 51. In the top view, the opening 53 extends substantially to a first end of the housing 51, wherein the housing 51 tapers in a cross-section or a side view in a direction away from the opening direction. The shape of the housing 51 is thus to the wallpapering brush 30 and to the above with reference to the Figures 1 and 2 illustrated wallpapering brushes 10, 20 adapted. In particular, a second end of the housing 51 facing away from the opening 53 can be designed as a drainage tip. If the wallpaper brush is not needed, it can easily be stowed in the bag 50. The wallpapering brush 30 is largely protected there from the drying or drying.

The top of the housing 51 is between the opening 53 and the second end, in a to FIG. 4 orthogonal cross-section, rounded and typically merges fluently into a rectangular shape in a lower region. The rounding to the middle part of the pocket 50 at the opening 53 is typically used to hold the handle portion.

Typically, a bracket 70 with a hinge 71 is attached to one side of the housing 51. This allows a secure and flexible attachment of the bag 50 on the work clothes of a painter, for example on the waistband, belt or side pockets. This can be a clip mechanism like his in FIG. 5 shown will be used. The temporary unnecessary wallpapering brush 30 can thus in the bag attached to the work clothes 50 can be stored easily, quickly and reliably. As a result, both the work efficiency and the work safety can be increased.

In addition, the pocket 50 is typically made of a plastic. The bag 50 is thereby relatively light and can also be easily cleaned, e.g. with water or an aqueous cleaning solution.

According to a further development, a clip holder 60, e.g. a plastic clip, fastened to a seam roller (not shown). This allows easy access to the Nahtroller or a simple exchange of Nahtroller and wallpapering brush 30 during wallpapering. As a result, the work efficiency and safety can be further increased.

Fig. 6 FIG. 12 shows a schematic side view of a pocket 50 'with a conventional wallpaper brush 90 housed therein. For clarity, neither an optional laterally mounted bracket with a hinge nor an optional underside mounted bracket for a close roller in FIG FIG. 6 shown. The top view of pocket 50 'is typically similar to that in FIG FIG. 5 shown supervision. In the top view, the pocket 50 'also has a substantially rectangular housing 51' with a typically oval opening 53 'for receiving wallpapering brushes. In a cross-section or in the side view, however, the housing 51 'hardly tapers in a direction away from the opening 53'. The shape of the housing 51 'thus allows both the recording of conventional wallpaper brushes 90 as well as the above with respect to the FIGS. 1 to 3 illustrated wallpapering brushes 10, 20, 30. If the wallpaper brush is not needed, it can be easily stowed in the pocket 50. The wallpapering brush is largely protected there from the drying or drying.

According to one embodiment, a wallpapering set includes a wallpapering brush 10, 20, 30 as described above with reference to FIGS FIGS. 1 to 3 explained, and a - as above with respect to the FIGS. 4 to 6 explained - pocket 50, 50 'for receiving the wallpapering brush 10, 20, 30. Typically, the papering set also includes a Nahtroller, which can also be held in the pocket 50, 50'. If the wallpaper brush 10, 20, 30 or the Nahtroller temporarily not needed, they can safely stowed in the bag 50, 50 'or exchanged become. This can increase both the work efficiency and the security when wallpapering.

The present invention has been explained with reference to exemplary embodiments. These embodiments should by no means be construed as limiting the present invention.
