Description

The invention relates to a tool with a handle and a bow-like and / or curved receiving part on which a roller for applying paint or wall paints is rotatably mounted and the receiving part by means of a pivotable about an axis connecting element to a linkage or to the handle is medium or directly connected such that the roller relative to the handle or the linkage about a longitudinal axis of the tool cutting adjusting axis adjusted, in particular pivoted, can be.

State of the art

Painter rollers are generally known, which serve from a bow-like bent metal rod with handle and a roller for applying paints or wall paints. With the help of the paint rollers can be preferred to edit large areas sometimes in inaccessible places and ensure a uniform application of paint. However, if they are used for example on surfaces behind radiators or in niches, ie between two fixed parts with a small gap, the paint roller can handle very bad, since the handle is rigid with the metal rod and thus the paint roller not far enough into the room between the two fixed parts can be introduced. Here the invention wants to remedy.

Furthermore, a tool with a handle and a bow-like and / or bent receiving part is known (US Pat. GB 748 626 A ). This shows a tool with a handle and a bow-like and / or bent receiving part on which a roller for the application of paints or wall paints is rotatably mounted. Further, the receiving part is connected depending on the training by means of a pivotable about one and a second axis connecting member to a linkage or the handle medium or directly such that the roller relative to the handle or the linkage about the longitudinal center axis of the tool cutting adjusting axis adjusted, in particular, can be pivoted. However, such a device with the very short spring connection is not suitable to be used in very long spaces, for example between the wall part and radiator, such that over the entire surface to be machined a uniform contact pressure is achieved. If the intermediate space has a large length, it is not possible to achieve a uniform contact pressure in the lower region of the intermediate space. The sole use of a very short spiral spring connection allows the use only for very specific and limited purposes. The known device can only be used as a special tool and can not be converted due to the fixed connection.

Also, the known device according to the US 2002/0148 062 A1 can only be used as a special tool due to the length and one turn of 360 °. The 360 ° winding between the roller and the handle part must have a very large bending moment in order to achieve a sufficient contact force. Due to the very large bending moment, the roll can be very difficult to handle in narrow spaces or move in a gap only up and down, especially as a certain angular position for the roller is specified by the 360 ° -Windung. Therefore, working with such a device for a long time is very tedious.

Also, the use of leaf springs between roller and handle after the US 2005/0015910 A1 brings no improvement. So that a uniformly high contact pressure of the roller can be achieved on the surface to be machined, the leaf spring must have a high bending resistance torque and a long length, so that it can be effectively used at long intervals while maintaining a uniform contact pressure. This makes the tool very unwieldy. In addition, leaf springs do not allow lateral bending, so this device can not be used for all work.

Disclosure of the invention

The invention has for its object to form and arrange paint roller and handle so that the paint roller can be used universally and also led to inaccessible places and used for inking.

The object is achieved in that the connecting element is a hinge connection, which is adjustable with a clamping connection for fixing a hinge part in a certain angle range against the action of a force, in particular against the action of a spring, which is the hinge part in the direction of processing Surface presses, or is a spiral or tube spring, which is formed variable in length and / or can be introduced and fixed in the handle or in a connected to the handle linkage.

This ensures that the tool with the roller for applying paints or wall paints even in very difficult to reach places, for example, in narrow spaces, as they occur when mounted on walls radiators, can be effectively used.

If the roller is guided into the space between a wall part and a radiator in the inventive design of the tool, the roller can also move over the entire length of the rear wall part and apply the paint on the wall. This is particularly possible because the connecting element is designed as a resilient part. With the help of the elastic connecting element, the roller can be introduced around an upper boundary edge of the radiator and into the intermediate space between the wall part and the radiator. If obstacles or protrusions occur, then due to the spiral or tube spring, the roller can also be adjusted about a further pivot axis and adapted very quickly to different conditions. With the help of the spiral or tube spring while maintaining a high elasticity and the resistance bending moment a uniform contact force is achieved. If the spiral or Bourdon tube is not needed, it can be inserted into the handle part or a linkage part and the tool converted without much time and continue to be used as a tool without spring element.

An additional possibility, according to a development of the invention, that with the help of the clamping connection, the joint part in a certain angular position between 15 ° and 180 ° can be determined.

Furthermore, it is advantageous according to another embodiment, that the connecting element with the handle or with the connected to the handle linkage and / or with the receiving part is releasably connectable.

Since the roll can not sometimes be passed through a narrow gap when the joint part is fixed, it is advantageous that the receiving part can still be moved within a certain angular range. By the spring of the necessary contact pressure of the roller is maintained on the application surface. This ensures a uniform application of paint on the surface to be processed.

If the roller is introduced into the space between a wall part and a radiator in the inventive design of the tool, the roller can also move over the entire length of the wall part and apply the paint on the wall, the spring ensures the clamp connection over the entire workflow in that the roller is pressed against the surface to be treated with a sufficient contact pressure.

In the illustration according to 1 is a tool 10 This is essentially a handle 14 and a bow-shaped and / or bent receiving part 16 exists on which a roller 18 is rotatably mounted for applying paints or wall paints. The roller 18 has a push-in cannula 20 on, in which the receiving part 16 can be pushed and is on the receiving part 16 secured with the help of a clip connection.

The recording part 16 is approximately U-shaped and has a coaxial with a longitudinal central axis 24 extending rod 12 on, which thread at one end 38 has that in a threaded bushing 39 an elastically formed connecting element 22 can be screwed.

This in 1 schematically illustrated connecting element 22 can be designed as a spiral or tube spring and has such a large bending moment that the tool 10 can be pressed with a sufficiently large contact pressure to the surface to be machined.

According to 1 is at the lower end of the connecting element 22 another threaded bush 42 provided in the one on the handle 14 provided thread 40 can be screwed. In this way, the receiving part can be 16 and the handle 14 easy to loosen and depending on the work use the connecting element 22 against another connecting element or against a hinge connection 28 exchange that in 4 is illustrated in more detail.

The articulation 28 consists of two via a clamp connection 34 used as a joint and locking screw 44 may be formed, movably interconnected joint parts 30 . 32 , with the help of the joint and / locking screw 44 in different angular positions, in particular at an angle α between 15 ° and 180 °, can be determined.

The roller 18 Can handle the opposite 14 or the linkage 36 around a longitudinal central axis 24 of the tool 10 cutting adjusting axis 26 adjusted or pivoted, be. The adjusting axle 26 runs coaxially to the joint and locking screw 44 ,

In a further embodiment, not shown in the drawing, the clamping connection 34 after fixing the one joint part 30 . 32 still in a certain angular range against the action of a restoring force, in particular against the action of a spring 46 , be adjustable, with the spring 46 the joint part 30 in the direction of the surface to be worked 33 behind a radiator 35 below a shelf 37 pressed.

According to 1 can the spring-elastic connection element 22 be formed variable in length or the two end portions of the connecting element 22 can be different depths either in the tubular end of a linkage 36 or in a not shown in the drawing tubular end of the handle 14 pushed and in different positions with the help of a clamping screw 48 be determined. In 1 is the connecting element 22 also reproduced in dashed positions. This makes it clear how far the roller 18 can be pivoted.

This in 4 partially illustrated linkage 36 , which can also be designed as a telescopic linkage, serves to receive the one joint part 32 or the elastic connecting element 22 , To one end of the linkage 36 is how in 1 illustrates the handle 14 screwed.
