Brief description of the drawings
Embodiments of the invention will now be described by way of example only with reference to the accompanying figures, in which:
Figure 1 is a front view of an accessory tool for a surface cleaning apparatus in accordance with an embodiment of the present invention;
Figure 2 is an underside view of the tool of figure 1; and
Figures 3 and 4 are differently annotated side views of the tool of figure 1.
Detailed description of embodiments
Referring to the figures, there is shown an accessory tool 1 in accordance with an embodiment of the present invention. The accessory tool is for use with a surface cleaning apparatus where the surface cleaning apparatus includes a source of suction. In this particular embodiment the accessory tool 1 may be an upholstery tool.
The tool 1 includes a body 10 which includes a dirty air inlet 12 which is in a tool surface 14. In use, the tool surface 14 and dirty air inlet 12 face a surface to be cleaned.
The tool surface 14 includes a forward portion 16 positioned forwardly of the dirty air inlet 12 to define a part of a first inlet section 20. The tool surface 14 further includes a rearward portion 22 which is positioned rearwardly of the dirty air inlet 12 to define a part of a second inlet section 24.
At least one thread lifting portion 26 including a thread lifting material 28 is positioned between the first and second inlet sections 20, 24. In other words, the at least one thread lifting portion 26 may be positioned between the forward portion 16 and rearward portion 22.
The provision of a thread lifting portion 26 between the first and second inlet sections 20, 24 has been found to be surprisingly effective in lifting thread (e.g. lint) from material surfaces. In particular, when thread is lifted from a surface being cleaned the dirty air inlet is in the vicinity of the thread lifting portion, to transfer the lifted thread to the source of suction.
The tool 1 may include a neck 17 connected to the body 10. An outlet 18 may be positioned at the top of the neck 17. The outlet 18 may be in fluid communication with the source of suction, in use. The outlet 18 may be fluidly connected to the dirty air inlet 12.
The neck 17 may have a generally elongate axis N which may form an angle β to the tool surface 14. The angle β may be between 30 to 60s. The angle β may be between 40 to 50s. The angle β may be 45s.
The neck 17 may function as a handle, in use.
The combination of the angle β being in the above described ranges and the neck 17 functioning as a handle means that the tool 1 may be easy to use. In particular, the tool surface 14 and the dirty air inlet 12 may be naturally presented at a convenient angle.
The forward portion 16 may include a thread lifting material 30.
The rearward portion 22 may include a thread lifting material 32.
The thread lifting material on the forward portion 16 may extend across 90% (or more) of the width of the forward portion 16 and/or the rearward portion 22. E.g. 95% or more of the width of the forward portion 16 and/or the rearward portion 22.
The thread lifting material on the rearward portion 22 may extend across 90% of the width of the forward portion 16 and/or the rearward portion 22. E.g. 95% or more of the width of the forward portion 16 and/or the rearward portion 22.
Providing such widths of thread lifting portions can help to increase the useable width of the tool.
The at least one thread lifting portion 26 may be positioned generally midway between the forward and rearward portions 16, 22. The tool 1 may include first and second thread lifting portions 26, 34 which correspond to the at least one thread lifting portion. Each of the first and second thread lifting portions may be provided with a thread lifting material 28, 36.
The first and second thread lifting portions 26, 34 may be positioned at peripheral regions of the dirty air inlet 12. In particular, they may be positioned at a left and a right edge 38, 40 of the tool, respectively.
The forward and rearward portions 16, 22 may be generally curved. In particular, in side cross-section as shown in figure 4, the forward and rearward portions 16, 22 may lie on a curve having a radius of curvature defined by a circle C’ having a radius R’ of between 40 mm and 50 mm. The radius R’ may be between 43 mm and 48 mm. The radius R’ may be approximately 46 mm. The use of such curved forward and rearward portions in embodiments may permit advantageous cleaning of upholstery products because it can reduce the contact area between the tool surface 14 and the upholstery depending on the shape of the upholstery. It may also assist with cleaning curved upholstery surfaces.
A rearward edge 44 of the rearward portion 22 may be positioned a distance L above the first and second thread lifting portions 26, 34. A forward edge 42 of the front portion 34 may be positioned a distance L above the first and second thread lifting portions 26, 34. The distance L may be between 5 mm and 9 mm. The distance L may be approximately 7 mm.
The first and second thread lifting portions 26, 34 may be generally planar. Alternatively, they may be generally curved. In particular, in side cross-section as shown in figure 4, the first and second thread lifting portions 26, 34 may lie on a curve having a radius of curvature defined by the circle C’ having a radius
R’ of between 40 mm and 50mm. The radius R’ may be between 43 mm and 48 mm. The radius R’ may be approximately 46 mm.
