Description

[0001] The invention relates, firstly, to a device for applying a flowable mass containing granules to a wall.

[0002] The device comprises a basin for receiving the mass. The basin has an open side, a bottom section opposite the open side, a first side section, a second side section opposite the first side section, a lower section, and an upper section opposite the lower section. The first and second side sections and the upper and lower sections terminate at the bottom section. Typically, the basin and the open side are formed by the bottom section, the first and second side sections, and the upper and lower sections. The basin is thus a basin-like vessel. The distance between the first and second side sections determines the length, and the distance between the upper and lower sections determines the width of the basin.

[0003] The device has a wall plane located on the open side. The first and second side panels, the top panel, and the bottom panel all terminate on this wall plane. The wall plane is a plane in the mathematical sense. The distance between the wall plane and the bottom panel determines the height of the tub.

[0004] The invention also relates to a method for applying a flowable mass containing granules to a wall using such a known device.

[0005] The user fills the known device with such a mass through the open end in the tub. The device is then placed with its open end against a wall. This wall extends upwards with respect to the Earth's gravitational field. The device is then moved upwards along the wall to apply the mass. The application process thus includes not only the application of the mass to the wall but also the smoothing of the applied mass in a single operation. However, the mass applied with the known device is less smooth and uniform than mass applied with a conventional device.

[0006] Conventional devices and methods for the manual and mechanical application of such a compound are known from the prior art. Manual application is carried out, for example, by a user who first applies the compound to a wall with a trowel and then smooths it with a float. Mechanical application is carried out, for example, by a user who first applies the compound to a wall with a spraying device and then smooths it with a float.

[0007] The known device and method for applying a mass with this device have advantages over the listed conventional devices and methods. Compared to machine application, the known device results in lower equipment costs, and compared to manual application, it results in lower application costs due to the reduced time required.

[0008] The object of the present invention is to provide a generic device and a generic method which eliminate or at least mitigate the disadvantage shown and retain the advantages shown.

[0009] The problem is solved by a device for applying a flowable mass containing granules to a wall, having the features of claim 1. The device has an outlet for the mass. The outlet is formed by a planar spacer strip attached to the lower part, parallel to the plane of the wall. The spacer strip thus lies in the plane of the wall. Preferably, the lower part and the spacer strip are integral and manufactured from a single piece.

[0010] The spacer strip has a defined width. When the flowable compound is applied, it flows across the width of the spacer strip. The spacer strip results in a smoother and more even application of the compound to the wall and better adhesion of the applied compound to the wall by applying additional pressure against the wall compared to the known device. It has also been shown that less compound is lost during application compared to the known device. Furthermore, the advantages of the known device are retained. Compared to machine application, the device costs are lower, and compared to manual application, the costs of execution are lower.

[0011] In one embodiment of the device, the spacer strip width is between 0.5 cm and 3 cm, and preferably between 1 cm and 2 cm. These spacer strip widths have proven particularly effective.

[0012] In a further embodiment, the outlet is additionally formed by a flat end strip adjoining the spacer strip. The end strip and the wall plane form an angle. This angle is preferably between 30° and 60°, and particularly preferably between 40° and 50°. In this embodiment, the outlet is thus formed by the lower part, the spacer strip adjoining the lower part, and the end strip adjoining the spacer strip. While the spacer strip is parallel to the wall plane, the end strip points away from the wall plane due to the angle. Preferably, the lower part, the spacer strip, and the end strip are manufactured in one piece.

[0013] In a further embodiment, the lower part and the wall surface form a funnel angle for feeding the mass to the outlet. The funnel angle is between 50° and 80°, and preferably between 60° and 70°. When the device rests against a wall, the wall, the lower part, and the first and second side parts form a funnel through which the mass flows more efficiently to the outlet.

[0014] In another embodiment, the device is a single piece, manufactured from one part. For example, the device is manufactured using a deep-drawing process. This embodiment is characterized by cost-effective and rapid production.

[0015] In another embodiment, the device is made of sheet metal or plastic. Sheet metal is advantageous due to its mechanical stability, and plastic due to its chemical resistance.

[0016] In a further embodiment, the tub has a volume for 7 kg to 9 kg and preferably for 7.5 kg to 8.5 kg of mass. Tests have shown that a device of this weight is still easily manageable for a user when applying the mass.

[0017] In a further embodiment, the length, i.e., the distance between the first and second side panels, is between 35 cm and 55 cm, and preferably between 40 cm and 50 cm. Tests have shown that a device of this length is still easily manageable for a single user and that sufficient stability is achieved without additional reinforcements. The device is therefore free of reinforcements.

[0018] In a further embodiment, the device for a plaster or filler is designed as the filler itself. The filler is therefore a plaster or a filler.

[0019] The problem is also solved by a method for applying a flowable mass containing granules to a wall according to claim 10 using one of the devices described above.

[0020] The method basically uses a device with a trough for receiving a flowable mass containing granules. The trough has an open side, a bottom section opposite the open side, a first side section, a second side section opposite the first side section, a lower section, and an upper section opposite the lower section. The device has a wall plane located in the open side, with the first side section, the second side section, the upper section, and the lower section terminating at the wall plane. The device has an outlet for the mass, the outlet being formed by a flat spacer strip adjoining the lower section parallel to the wall plane.

[0021] A user performs the following steps using the device: As a first step, the tub is filled with the mixture. This is done through the open side. In a second step, the filled device is placed against a wall with its open side facing down. The wall surface rests on a surface of the wall. The outlet points downwards. In a third step, the filled device, which is positioned against the wall, is moved from bottom to top to apply the compound. In this third step, the compound is applied to the wall and smoothed, meaning it is completely covered.

[0022] An advantage of the method according to the invention is that, due to the outlet, the mass is applied more smoothly and evenly to the wall when the device is moved from bottom to top than when using the known device.

[0023] For one embodiment of the method, the outlet of the device is additionally formed by a planar end strip adjoining the spacer strip, and the end strip and the wall plane forming an end angle.

[0024] In this configuration, after moving the device from bottom to top along the wall to ensure an even application of the compound, the user rotates the device around the finishing angle at the end of the application so that the finishing strip is parallel to the wall, and then lifts it away. This presses the compound and finishing strip against the wall, preventing it from detaching when the device is subsequently lifted. The aforementioned areas of the finishing angle are advantageous because they are easily accessible to the user.

[0025] Furthermore, the statements regarding the device apply accordingly to the procedure and vice versa.

[0026] In detail, there are numerous possibilities for designing and further developing the device and method according to the invention. Reference is made, on the one hand, to the claims subordinate to claims 1 and 10, and on the other hand, to the following description of an exemplary embodiment in conjunction with the drawing. The drawing shows Fig. 1. A first perspective view of a device for applying a flowable mass with granules, Fig. 2 a second perspective view of the device, Fig. 3a a view of the device when used against a wall in a starting position, Fig. 3b a cut side view of the view from Fig. 3a, Fig. 3c a view of the device when used against the wall in an end position and Fig. 4. A flowchart of a procedure for applying the mass with the device.

[0027] The Fig. 1 and Fig. Figure 2 shows two perspective abstracted views of a device 1 for applying a flowable mass 2 with grains 3, see here Fig. 3b. The mass 2 here is a plaster.

[0028] The device 1 has a trough 4 for receiving the mass 2. The trough 4 has an open side 5, a bottom section 6 opposite the open side 5, a first side section 7, a second side section 8 opposite the first side section 7, a lower section 9, and an upper section 10 opposite the lower section 9. The first side section 7, the second side section 8, the lower section 9, and the upper section 10 terminate on the bottom section 6. The device 1 has a wall plane 11 located in the open side 5. The first side section 7, the second side section 8, the upper section 10, and the lower section 9 terminate on the wall plane 11. The trough 4 and the open side 5 are formed by the bottom section 6, the first side section 7, the second side section 8, the lower section 9, and the upper section 10. It is a basin-like vessel.

[0029] Furthermore, the device 1 has a flat spacer strip 12 and a flat end strip 13. An outlet 14 of the device 1 for the mass 2 is formed by the spacer strip 12 adjoining the lower part 9 and the end strip 13 adjoining the spacer strip 12. The spacer strip 12 lies in the wall plane 11. The spacer strip has a width of b = 1.5 cm. The end strip 13 and the wall plane 11 form an angle α = 45°. While the spacer strip 12 is parallel to the wall plane 11, the end strip 13 points away from the wall plane 11 due to the angle α.

[0030] The lower part 9 and the wall plane 11 form a funnel angle β = 65° for better feeding of the mass 2 to the outlet 14 when using the device 1, see here Fig. 3b.

[0031] A distance between the first side panel 7 and the second side panel 8 determines a length l = 45 cm, a distance between the upper part 10 and the lower part 9 determines a width b, and a distance between the wall plane 11 and the bottom part 6 determines a height h of the tub 4. The outlet 14 extends over the length 1. The width b and the height h are determined for the given length l such that the tub 4 can accommodate a mass 2 with a density of 8 kg. Reinforcements of the device 1 are not required for the selected size and weight of the mass 2.

[0032] The Fig. 3a, Fig. 3b and Fig. Figure 3c shows the device 1 during the execution of a method for applying the flowable mass 2 by a user not shown. Fig. Figure 4 shows a flowchart of the procedure.

[0033] The user performs the following steps: In a first step, 101, the tub 4 is filled with 8 kg of the flowable mass 2. The filling takes place in the Fig. Figure 1 shows the orientation of the device 1 with respect to an Earth's gravitational field. The Earth's gravitational field is represented by an Earth gravitational field vector g.

[0034] In a second step 102, the device 1 is placed with its open side 5 against a wall 15 extending upwards with respect to the Earth's gravitational field, so that the outlet 14 is directed downwards. When the device 1 rests against the wall 15, the wall plane 11 and a surface of the wall 15 initially coincide. The wall 15, the lower part 9, the first side part 7, and the second side part 8 form a funnel through which the mass 2 flows to the outlet opening 14. The wall 15 is vertical and is only oriented in the Fig. 3a and Fig. 3c is shown at an angle for better illustration. Fig. Figure 3a shows the device 1 at a lower end of wall 15 in a starting position. However, the method and the device also work with inclined walls. The size and weight of the device 1, filled with mass 2, are still easily manageable for a user during this movement.

[0035] In a third step 103, the device 1, which rests against the wall 15, is moved from bottom to top along the wall 15 to apply the mass 2. This movement creates a wall gap d between the spacer strip 12 and the surface of the wall 15, corresponding to the size of the grains in the flowable mass 2. The wall plane 11 and the surface of the wall 15 no longer coincide. The outlet 14 with the spacer strip 12 results in a more uniform application of the mass 2 to the wall 15 and better adhesion of the mass 2 to the wall 15 by additionally pressing the mass 2 against the wall 15 than the known device. Fig. Figure 3b is a cutaway side view showing the device 1 during application.

[0036] In a fourth step 104, after completion of the movement from bottom to top on the wall 15, to ensure a uniform application of the mass 2 on the wall 15, the device 1 is also rotated in a final position by the closing angle α = 45° so that the closing strip 13 is parallel to wall 15 and has the wall distance d. Fig. Figure 3c shows the device at the upper end of wall 15 in this final position. The device 1 is then lifted away from wall 15. The end angle α is easily accessible to the user.
