VACUUM CLEANING NOZZLE

Abstract: A vacuum cleaning nozzle has at least one housing (1) enclosing a chamber (2) with a suction opening (3) to be applied to the work surface, and has a tube (4) connectible to the vacuum cleaner. The connecting tube is connectible to the housing by means of a pivot device (5). The housing (1) is in the form of two legs (8, 9) disposed at an angle relative to one another, each leg having a freely projecting end portion (10, 11). The pivot device (5) has two pivot axes (12, 13) which are disposed transversely relative to one another. By means of these axes the connecting tube (4) and the housing (1) are pivotable in relation to one another. The first axis (12) extends generally parallel to the work surface and the second axis (13) is turnable between different positions in a plane intersecting that of the first axis. The pivot device (5) is arranged so as to cause the nozzle to turn on the work surface when the connecting tube (4) is twisted about its length axis (14).

Description: Vacuum cleaning nozzle This invention relates to a vacuum cleaning nozzle having at least one housing enclosing a chamber with a suction opening to be applied to the work surface, and having a tube connectible to the vacuum cleaner and being connected to the housing by means of a pivot device, the housing having at least two edge portions disposed at an angle relative to one another. Vacuum cleaning nozzles are known which are difficult to use effectively under low furniture and cannot be used in narrow spaces. This is due to the fact that the nozzle cannot be turned through 90° maintaining its contact with the work surface when the connecting tube of the vacuum cleaner is lowered to a level parallel to the work surface and below the upper surface of the nozzle. Further, vacuum cleaning between legs of furniture cannot be done but the furniture has to be moved to allow satisfactory cleaning of the work surface. This depends on the comparatively large width of the nozzle in combination with its restricted pivoting capacity. The object of the invention is to make it possible to use the entire capacity of the vacuum cleaner also in the cases related above and the invention is for that purpose generally characterized in that the housing is in the form of two legs which are disposed at an angle relative to one another, each leg having a freely projecting end portion, and in that the pivot device has two pivot axes which are disposed transversely relative to one another and by means of which the connecting tube and the housing are pivotable in relation to one another and of which the first axis extends generally parallel to the work surface and the second axis is turnable between different positions in a plane intersecting that of the first axis, the pivot device being arranged so as to cause the nozzle to turn on the work surface when the connecting tube is twisted about its length axis. An embodiment of the invention will be described below with reference to the accompanying drawings, in which Fig. 1 is a perspective view of the nozzle, Fig. 2 is a view of the nozzle seen from below and Figs. 3 - 5 are schematic views of the nozzle in different work positions, illustrated by symbols in the left margin. The nozzle shown in Figs. 1 and 2 comprises a housing 1 enclosing a chamber 2 with a suction opening 3. A tube 4 for a suction hose, not shown, is connectible to the housing. By means of a pivot device 5 the connecting tube 4 is pivotally connected to the housing 1, which has two edge portions 6, 7 of the OMPI legs 8, 9 disposed at an angle to one another, each leg having a freely projecting end portion 10, 11. The angle o-z. between the edge portions 6, 7 is about 90 . The pivot device 5 has two pivot axes 12, 13 which are disposed transversely relative to one another and by means of which the connecting tube 4 and the housing 1 are pivotable in relation to one another. The first pivot axis 12 extends generally parallel to the work surface and the second pivot axis 13 is turnable between different positions in a plane intersecting the axis 12. Further, the pivot device 5 is arranged to cause a turning movement of the housing 1 on the work surface when the connecting tube 4 is twisted about its length axis 14, as will appear in the following. The pivot device 5 comprises two tubular parts in the form of two sleeves 15, one for each leg 8, 9, and an intermediate tube 16 joining the connecting tube 4 to the housing 1 at two places, one for each leg 8, 9. By means of its two end portions 17, 18 the intermediate tube 16 is turnably journalled in the two sleeves 15 about the first pivot axis 12, and the intermediate tube 16 has a third end portion 19 by means of which the connecting tube 4 is pivotally journalled about the second pivot axis 13. The length axis 14 of the connecting tube 4 forms an angle with the axis 13. The length axis 14 extends at a distance from the pivot axis 12 except in the working position shown in Fig. 5. The connecting tube 4 is freely pivotable about the second pivot axis 13. As seen from Figs. 3 and 4, the connecting tube 4 is connected to the pivot device 5 in such a manner that it can be held at a level above the work surface and still be below the upper surface of the nozzle. It will be seen from Figs. 1 and 2 that along the two sides of the legs apertures are provided which, when the housing 1 is in contact with the work surface, form laterally directed suction openings 20, 21. The openings 21 are situated at the inside of the housing 1 near the front edge joining the legs 8, 9 and the openings 20 are situated at the outside of the housing generally in the middle of each leg 8, 9. Thanks to the design of the nozzle as shown in Fig. 4 and related above, vacuum cleaning with full suction effect, i.e. with full contact with the work surface, is possible under low furniture. In addition, the turning capability of the nozzle largely improves the access close to and around other objects on the work surface. Due to the small contact surface at the front edge and the outside of the legs good suction effect will be obtained in corners of 90 , at floor lists etc. The invention is not limited to the embodiment described above and shown in the drawings but several modifications are possible within the scope of the following claims.
