DETAILED DESCRIPTION OF DRAWINGS

[0074] FIG. 1 shows an embodiment of a dusting and dust collecting device, according to the present invention. The device comprises an elongated body A (not shown) covered by a dust brushing means D in form of a brush D made from a plurality of fluffy fibers, threads or ribbons. The fluffy fibers, threads or ribbons having electrostatic properties with a high-dust-attracting power, in that the fabric accumulates dust, debris and particles. The dust brushing means D is a refill and replaceable device, which can be replaced after use. The FIG. 1 shows a preferred embodiment of the device according to the present invention, the device is ready for connection to a vacuum source indirectly through an adaptor-head B. The adaptor-head B comprises a form-shaped handle grip, a first end 12, and a second 13 (not shown) end.

[0075] FIG. 2 shows an embodiment of a dusting and dust collecting device according to the present invention. The device comprises a hollow body A in form of an elongated tube A. The elongated tube A comprises one open end 11 and one free end 3.

[0076] The open end 11 comprises a fastening means 4 in form of an extended key lock section 4 for quick and easy locking of the tube 4 to an adaptor-head B. According to the invention, other fastening means can also be used, such as friction lock, snap lock, spigot joint, screw lock, and other similar quick locking mechanism. The adapter-head B comprises a handle grip together with a first end 12 and a second end 13. The first end 12 being adapted to be releasable connected to the external vacuum source and the second end 13 being adapted to be releasable connected to the open end 11 of the elongated tube A. An eject button 7 is located on the upper part of the adaptor-head B for the quick and easy release of the elongated tube A. The elongated tube A can be connected directly or indirectly by means of an adaptor-head B to a vacuum source, such as a vacuum cleaner. The elongated body A further comprises a plurality of grooves 1 arranged in parallel to each other and perpendicular in the longitudinal direction of the elongate tube A. Corresponding grooves (not shown) can also be arranged on the inside shell-surface of the hollow elongated tube A, making the elongated tube A more bendable and flexible. Each groove 1 is again connected to a perforation hole 2 with opening extending into the hollow tube A. When pulling a dust brushing means D outside the grooves 1, and covering the elongated tube A, a series of canals are created on the surface of the tube A. When the elongated hollow tube A is connected to a vacuum source, such as a vacuum cleaner, an under pressure (suction) or vacuum is created in the canals associated with the at least one perforation hole on the body A. This arrangement distributes the vacuum-sphere and the ability to control the airborne dust surrounding the elongated tube A. The grooves 1 also make the elongated tube more supple and flexible, increasing the stealthy effect and access to narrow and hard to reach places. As shown in FIG. 2 the perforations 2 has form as square shaped holes located on the elongated tube A. The number of perforations can vary according to the different shapes and lengths of the hollow body A. FIG. 2 shows 7 holes at one side of the elongated tube A. The holes 2 on the other side of the tube may preferably be displayed with a longitudinally offset so that they are covering a different section of grooves (not shown).

[0077] FIG. 2 also shows the free end 3 of the elongated tube A, having a sloping shape with two suction holes. These suction holes can be seen more clearly in FIG. 3. Also seen from FIG. 2 are the main suction hole 5 located below the first end of the adaptor-head B. Further, a valve 6 is located at each side of the adaptor-head B. The valve 6 comprises a plurality of flaps arranged at the opening. The valve 6 is readily available and controlled by a thumb or any other finger of the user. Same arrangement of the valve 6 at the opposite end of the adaptor-head B, allows the device to be used both by right or left handed. At the second end 12 of the adaptor-head, B a converter C is arranged for the easy adaption of the adaptor-head B to intake of the different vacuum source (not shown).

[0078] FIG. 3 shows the dusting and dust collecting device according to the present invention seen from below. The free end 3 of the elongated tube A comprises two suction holes. Also shown are the pluralities of grooves/canals 2 together with the associated perforation holes 2. The elongated tube A is adapted to be inserted into the adaptor-head B. At the connection point between the hollow body and the adapter-head, a flexible chock joint 14 is arranged. The flexible chock-joint 14 are preferably made from an elastic material for easy and thigh locking of the elongate tube A. Preferably, the locking of the elongate tube A is made by friction between the flexible chock joint 14 and the surface of the elongate tube A. The main suction hole 5 is arranged below the connection point and at least one valve 6 is located at one side of the adaptor-head B.

[0079] FIG. 4 shows the dusting and dust collecting device according to the present invention seen from above. The eject button 7 located at the top part of the adaptor-head B.

[0080] FIG. 5 shows the adapter-head B with a handle grip together with a first (not shown) and a second end 13. The first end 12 being adapted to be releasable connected to the external vacuum source and the second end 13 being adapted to be releasable connected to the open end 11 of the hollow longitudinal tube A. Further, the second end 13 comprises a flexible chock-joint 14 to improve the accessibility of the hollow longitudinal tube A when attached to the adaptor-head B, allowing the tube A to flex in different directions. The flexible chock joint 14 acts as a flexible coupling section of the hollow body A, providing a better user experience, and increases the creep function and being secured with a key-lock/pin-lock, locking the body to the adaptor-head B. In the preferred embodiment of the present invention, the key-lock 4 comprises an elongated locking pin 4, which engages a recess in the adaptor-head B, such as a click on snap-lock locking device.

[0081] FIG. 6 shows another embodiment of the present invention where the hollow body A has an elongate tube shape and comprises a plurality of grooves 1 in connection with one perforation 2. The perforation 2 has also an elongate shape and situated at the underside of the hollow body A, viewed in a user position. According to the invention, the one perforation can have different shape and situated at different areas on the hollow body A.

[0082] Within the scope of the invention, each of the plurality of grooves 1 has an annular shape and arranged in parallel to each other, and over at least a part of a length of the elongate hollow body A. The FIG. 6 shows an embodiment of the present invention where a plurality of annular grooves 1 is on the outer circumference of the hollow body A, and the plurality of grooves 1 is arranged over a part of the length of the elongate hollow body A. According to a preferred embodiment of the present invention, the plurality of grooves 1 is situated perpendicular and arranged over the entire length of the elongate hollow body A.

[0083] FIG. 7, shows yet another embodiment of the present invention, where a plurality of perforations 2 is arranged on the outer surface shell surface and over the entire length of the elongate hollow body A. Each perforation 2 has a circular shape, and wherein each perforation 2 extends from the hollow section of the hollow body A and through the outer shell and connects with one of the grooves 1, for distributing a vacuum in the canal when a dust brushing means (D) is fitted over and covering the groove 1, and the hollow body A is connected to a vacuum source (not shown). According to the invention, the perforation 2 can have different shape and situated at different positions. The FIG. 7 shows the one perforation in connection with one canal, the perforations situated on the underside of the elongate hollow body A viewed in a user position. FIG. 8, shows yet another embodiment of the present invention where the elongate hollow body A comprises a plurality of perforations 2 arranged on the underside of the body A viewed in a user position. The elongate hollow body A has a substantially oval shape with a flatter bottom section, giving a stiffer and more stable elongate body A. The FIG. 8 also shows the embodiment with one perforation 2 in connection with one canal.
