Description
1 2396799 Auxiliary Cleaning Tool of Vacuum Cleaner This invention relates
to a cleaning tool of a vacuum cleaner, and in particular to an auxiliary cleaning tool, provided on a manipulation handle of a vacuum cleaner, for cleaning a narrow space, and is easily switchable between a cleaning mode and a standby mode.
As is well known, a vacuum cleaner performs sucking and removal of dust and contaminants from a surface to be cleaned by using a suction force generated by a l O vacuum-generating device. Such a cleaner is capable of cleaning not only a large space, such as a floor, but also a narrow space such as a window sill.
In order to perform a variety of cleaning tasks, a vacuum cleaner generally includes a suction brush which is used as a main cleaning tool for cleaning large spaces, and a so-called 'crevice brush', i.e., an auxiliary cleaning tool for cleaning narrow spaces.
Figure I is a perspective view showing schematically a known vacuum cleaner having a cleaner body 10 in which main components such as a vacuum-generating device are mounted. A flexible hose assembly 12 is connected to the cleaner body l0, this assembly having a manipulation handle ll. An extension pipe 13 is removably connected to the manipulation handle 11. A suction brush 14 is connected to an end of the extension pipe 13, the suction brush constituting a main cleaning tool.
A clip 16 is attached to the extension pipe 13, the clip being provided for holding a crevice brush 15 constituting an auxiliary cleaning tool when that tool is not in use.
When a user wishes to use the crevice brush 15, the crevice brush is detached from the clip 16 and connected to the extension pipe 13, replacing the suction brush 14.
Alternatively, the crevice brush 15 can be connected directly to the manipulation handle 1 1 of the flexible hose assembly 12.
Unfortunately, an auxiliary cleaning tool of this type is inconvenient to use, because a user has to connect the crevice brush 15 to the extension pipe 13 or to the manipulation handle 11, while the crevice brush is held by the clip 16 when not in use.
The aim of the invention is to solve the above problem in the prior art, by providing a vacuum cleaner auxiliary cleaning tool which is easy to use because it is switchable between cleaning and standby modes by simple manipulation.
The present invention provides an auxiliary cleaning tool for a vacuum cleaner, the tool 1 0 comprising: a substantially cylindrical cleaning tool body disposed on a manipulation handle of the vacuum cleaner for movement between a cleaning mode, in which the cleaning tool body in advanced, and a standby mode, in which the cleaning body is retracted; the cleaning tool body having a pair of cleaning tool members which are formed by symmetrically cutting a portion of the cleaning tool body along a longitudinal direction to define wedge-shaped recesses, each recess tapering from one end to the other end of the cleaning tool body; the cleaning tool members being connected to each other by hinge pins and being pivotable about the hinge pins to open and closed positions; and pivoting means for moving the cleaning tool body between the cleaning mode and the standby mode, the pivoting means being such as to pivot the cleaning tool members towards one another in the cleaning mode, and to pivot the cleaning tool members away from one another in the standby mode.
In a preferred embodiment, the pivoting means comprises: two pairs of guide protrusions, one guide protrusion of each pair being disposed in a rear portion of a respective cleaning tool member symmetrically opposite to the guide protrusion in the other cleaning tool member; and a slider having two pairs of guide holes, the slider being connected to the cleaning tool body by engagement of the two pairs of guide protrusions with the guide holes to guide the movements of the guide protrusions, the guide holes of each pair being inclined towards one another in such a manner that the distance therebetween gradually increases towards the rear portion.
Preferably, each hinge pin is spaced from a front end of the respective cleaning tool S member by as much as 4/5 length of that cleaning tool member.
The invention will now be described in greater detail, by way of example, with reference to the drawings, in which: Figure 1 is a perspective view of a known vacuum cleaner showing its auxiliary cleaning tool in a standby mode; Figure 2 is a perspective view showing a vacuum auxiliary tool constructed in accordance with the invention; Figure 3 is an exploded perspective view showing the cleaning tool body of the auxiliary cleaning tool of Figure 2; Figure 4 is a perspective view showing the cleaning tool body of Figure 3 in an assembled state; and Figures 5A to 5B are perspective views showing the auxiliary cleaning tool in a standby mode and a cleaning mode respectively.
Referring to the drawings, Figures 2 to 4 show a vacuum cleaner auxiliary cleaning tool having a cleaning tool body 30 movably disposed on a manipulation handle 20 for movement between a cleaning mode (in which the cleaning tool body is advanced) and a standby mode (in which the cleaning tool body is retracted). Pivoting means 40 are provided for switching the cleaning tool body 30 between the cleaning mode and the standby mode. In the cleaning mode, the cleaning tool body 30 has one end narrowed in diameter; while, in the standby mode, the cleaning tool body has that end extended in diameter.
The cleaning tool body 30 has a pair of cleaning tool members 31, 32 which are formed by symmetrically cutting wedge-shaped recesses from a generally cylindrical body member, each recess tapering gradually from one end of the cleaning tool body towards the other end thereof. The cleaning tool members 31, 32 are connected to each other by hinge pins 33 (see Figures 3 and 4), and pivot about the hinge pins to open and close.
Each of the cleaning tool members 31, 32 has a semicircular section, and has a pair of inclined longitudinal sides defined by the wedge-recesses. Accordingly, each of the cleaning tool members 31, 32 tapers from one end thereof to the other end.
Each hinge pin 33 is spaced from the front (the left end as shown in Figure 2) of the cleaning tool members 31, 32 by 4/5 of the length of those members. The cleaning tool members 31, 32 respectively have hinge pieces 31a, 32a formed integrally therewith, into which the hinge pins 33 are inserted.
The cleaning tool members 31, 32 of the cleaning tool body 30 pivot about the hinge pins 33 to open and close. Accordingly, inward pivotal movements of the cleaning tool members 31, 32 cause the inclined surfaces thereof closely to contact with each other, and outward pivotal movements cause those inclined surfaces to move apart. Thus, the cleaning tool body 30 has its front end narrowed in diameter following inward pivotal movements, while its front end is extended in diameter following outward pivotal movements.
The pivoting means 40 includes a slider 44 and two pairs of guide protrusions 41, 42, a respective guide protrusion of each pair being disposed in the rear portion of each of the cleaning tool members 31, 32, and the guide protrusion being symmetrically disposed.
The slider 44 has two pairs of guide holes 43 corresponding to the guide protrusions 41, 42. The slider 44 is connected to the cleaning tool member 30 by inserting the two pairs of guide protrusions 41, 42 into the two pairs of guide holes 43. The guide holes 43 are formed in an inclined manner, so that the distance therebetween becomes gradually broader towards the rear portion. It should be noted that, in Figure 2, only one pair of guide holes 43 is shown, while the other pair is hidden.
Accordingly, when the guide protrusions 41, 42, which are received in the guide holes 43, are moved to the front portions of the guide holes, the end of the cleaning tool body is extended in diameter. When the guide protrusions 41, 42 are moved towards the rear portions of the guide holes 43, the end of the cleaning tool body 30 becomes narrowed in diameter.
Hereinafter, the operations of the auxiliary cleaning tool in a cleaning mode and a standby mode will be described.
Figure 5A illustrates the cleaning tool body 30 and the manipulation handle 20 in a standby mode. As shown in Figure SA, the cleaning tool body 30 is in the retracted position with respect to the manipulation handle 20, so that the guide protrusions 41, 42 of the cleaning tool members 31, 32 are disposed in the front portions of the guide holes 43 formed in the slider 44. With the auxiliary cleaning tool in the standby mode, the manipulation handle 20 is connected to an extension pipe (not shown) of the vacuum cleaner (not shown), so that the vacuum cleaner can clean a large space using a main cleaning tool.
When a user wishes to use the auxiliary cleaning tool instead of the main cleaning tool, the extension pipe is separated from the manipulation handle 20 and the slider 44 is moved to a forward portion of the manipulation handle 20, thereby bringing the cleaning tool body into the cleaning mode. As the slider 44 advances, the guide protrusions 41, 42 move along the guide holes 43 so that the cleaning tool members 31, 32 pivot about the hinge pins 33 to close.
finally, the cleaning tool body 30 has its end narrowed in diameter as shown in Figure 5B, thereby being enabled to perform cleaning of a narrow space. After narrow space cleaning, the cleaning tool body 30 and the slider 44 are retracted, and the cleaning tool body is moved to the standby mode by the cooperation of the guide protrusions 41, 42 and the guide holes 43. Accordingly, the end of the cleaning tool body 30 is extended in diameter.
As described above, the auxiliary cleaning tool can always be held by the manipulation handle 20 without having to use an extra holding clip when not in use. Also, the auxiliary cleaning tool can be switched to the cleaning mode by a simple manipulation.
Since it is easy to switch the auxiliary cleaning tool between the cleaning mode and the standby mode by simple manipulation, the vacuum cleaner is convenient to use, and there is no danger of losing the auxiliary cleaning tool.
