Description

DEVICE FOR THE APPLICATION OF TAPE ONTO A SURFACE

The present invention relates to a device for arranging a tape on a surface, particularly for arranging a scrim tape on a plasterboard surface, such as a plasterboard wall or ceiling.

Diverse devices for arranging tape are known, particularly for arranging tape on packages. Such devices usually comprise a holder for a roll of tape, a guide for guiding the tape as it is moved over a surface, and a blade with which the tape can be severed by making a rotating movement with the device.

Such devices are useful for their primary purpose of sealing packages but are found to be less suitable for arranging tape on other surfaces, such as plasterboard walls, or walls or similar surfaces to be masked with tape for work purposes. They are particularly unsuitable for arranging a tape at locations which cannot be reached without auxiliary means, such as ceilings and high parts of walls.

It is therefore an object of the present invention to provide a device which at least partially obviates the above stated drawbacks, or to provide a usable alternative.

The invention relates for this purpose to a device for arranging a tape on a surface, comprising a frame, a holder, such as a roll, for the tape connected to the frame, a guide for guiding the tape in a path away from the holder, and a blade which is movable relati ve to the frame between a first position, in which it lies outside the path of the tape, and a second position in which it intersects the path of the tape.

The movable blade makes it possible to cut the tape without having to rotate the whole device. The number of situations and options for which the device is usable is hereby increased considerably compared to a conventional device for arranging tape. The device can now be moved to an end position while arranging tape on the surface, and at the end position the blade can be moved from the first position to the second.

The guide can comprise a first guide part and a second guide part arranged on an outermost side of the frame for allowing the path of the tape to extend therebetween. By making use of two guide parts the tape can be pulled tight between the two locations where it is carried along the guide parts, which simplifies severing.

The first and/or second guide part can comprise an (optionally curved) plate or a rod or bush, but can for instance also comprise a roller. The tape hereby undergoes a minimal friction resistance and can be arranged easily on a surface.

In order to arrange tape in scrim form for the purpose of plastering plasterboard walls or ceilings the first and second tape guides are preferably at least 5 cm wide. It has been found in practice that narrower tape guides do not allow the tape to adhere properly to the edges of plasterboard adjacently of a groove for covering. Nor at a width

considerably greater than 5 centimetres can the tape be pressed down optimally because the guide then no longer presses the tape at the position of the groove. The blade is for this purpose preferably also at least 5 cm wide, and preferably slightly wider than the type of tape to be used.

In an embodiment the device comprises a spring element for urging the blade at rest to the first position. The force generated by the spring is preferably greater here than the pressing force required for arranging the tape on a surface. The device can then be used to arrange a tape by rolling or sliding it over the surface with a limited pressure and to then cut the tape by then pressing the device with a greater force against the surface.

For simple operation at distance the device can comprise a transmission for operating the blade at distance between the first and the second position, which transmission can particularly be provided with a coupling means for a rod. The tape can in this way be arranged by moving the device along the surface using the rod with a first pressing force sufficient to bring about adhesion of the tape, and be severed by pressing the rod against the surface with a greater force sufficient to move the blade. The use of a rod or handle also makes it unnecessary to bent down or for a stepladder to be used for small heights.

For a construction which is robust and easy to manufacture the frame can be at least partially punched from a metal sheet. The frame can be embodied here for safety purposes such that it encloses the blade at least at the first position. In the case of a frame punched from metal sheet, the metal sheet can be provided with a protrusion for enclosing the blade.

When a tape has been cut it may tend to drop off the first and/or second guide part, requiring an additional operation to return the tape to the correct position. So as to prevent the necessity for this operation a stop can be provided for the purpose of catching an end of a severed tape connected to the roll.

It is also possible to arrange the blade rotatably for the purpose of adjusting the cutting surface to a surface to be provided with the tape. The blade can then adjust itself to the surface when a force or pressure is being exerted for the cutting movement.

The invention will now be elucidated with reference to the following figures. Herein:

• Figure 1 shows a perspective view of a device according to the invention;

· Figure 2 shows a perspective view of a detail of the invention; and

• Figure 3 shows the application of the invention for the purpose of arranging a tape.

Figure 1 shows a device 1 for arranging a tape on a surface, with a frame 2, a holder 3 for the tape (not shown) connected to the frame and formed by a roll, a guide for guiding the tape in a path away from the holder and formed by a first guide part 4a and a second guide part 4b, both formed by a roller, and a blade 5 movable relative to frame 2 between a first position (shown) in which it lies outside the path of the tape; and a second position (not shown) in which it intersects the path of the tape. The first and second guide parts have a width 10 of at least 5 cm. Also shown is spring element 8 which serves to urge blade 5 at rest to the first position. Blade 5 is arranged on a transmission 9 for operation of the blade at distance between the first and second position. A guide block 15, which can for instance be ernbodied in nylon, is placed in order to allow smooth displacement of the blade and to prevent friction occurring. A bush 19 provided for the purpose of guiding the transmission can also be arranged rotatably.

Also shown is that a slot 16 is provided in frame 2 through which a cam 17 connected to transmission 9 moves during movement of the transmission. The length of slot 16 determines the stroke which the transmission can perform. In a preferred embodiment this is chosen such that the blade does not quite touch a surface to be provided with tape when the device lies at an angle of between 40 and 50, and in particular about 45 degrees, to the surface. Particularly in corners as shown in figure 3c, this results in damage to the surface by the blade being prevented.

The projection 18 on which roll holder 3 is mounted is placed such that the roll does not touch the surface and does not impede the user during arranging of the tape. The transmission is shown in detail in figure 2 and is provided with a coupling means 12 for a rod.

The figure also shows how frame 2 encloses blade 5 at the shown first position, in that the metal sheet is provided with a protrusion 7 for enclosing the blade and in that the device is provided with a stop 6 for catching an end of a severed tape connected to roll 3. Finally shown in figure 1 is that the blade is arranged for rotation around a rotation point 1 1 for the purpose of adjusting the cutting surface to a surface to be provided with the tape. Figure 2 shows transmission 9 of device 1 of figure 1 for operation of the blade at distance between the first and second positions. The transmission is provided with a coupling means for a rod and the blade is arranged for rotation around a rotation point 1 1 for the purpose of adjusting the rotation angle V to the surface to be provided with tape.

Figure 3 shows device 1 of figures 1 and 2 during use. In situation A the tape 13 is arranged on a surface 14 (in this case a ceiling). Device 1 supports with guide part 4a on surface 14 and the tape adheres thereto. The blade is in the first position. In situation B the tape 13 is unrolled further using device 1 and the device supports with both guide part 4a and guide part 4b on the surface. The blade is still in the first position. In situation C the tape 13 is unrolled to the desired length using device 1 and the blade is carried to the second position by exerting a force F, whereby the tape is severed. The part of tape 13 not arranged on surface 14 rests on stop 6 and can thereby be brought quickly into position again for the purpose of arranging a subsequent strip of tape.
