- Figure 1 is a perspective view of a cleaning apparatus
- Figure 2 is a partial sectional view of the cleaning apparatus shown in Figure 1;
- Figure 3 is a perspective view of part of the cleaning apparatus shown in Figure 1;
- Figure 4 is an exploded view of part of the cleaning apparatus shown in Figure 1;
- Figure 5 is a perspective view of part of the cleaning apparatus shown in Figure 1 in a disengaged configuration.
- Figure 1 shows a vacuum cleaning apparatus 2 comprising a handheld vacuum cleaner 4 and a cleaning implement 6 comprising a tubular wand 8 and a cleaner head 10.
- the handheld vacuum cleaner 4 comprises an elongate handle 12, an airflow generator 14 disposed at one end of the handle 12 and a power source 16 disposed at the other end of the handle 12.
- the handle 12 is arranged such that a user gripping the handle supports the vacuum cleaning apparatus 2 while manoeuvring the cleaner head 10 across a surface being cleaned.
- the handle 12 is located towards the rear of the handheld vacuum cleaner 4 so that the vacuum cleaner 4 can be supported in front of the user.
- the handheld vacuum cleaner 4 further comprises a separator 18, in the form of a cyclonic separator, and a first connector 20.
- the first connector 20 is positioned towards the front of the handheld vacuum cleaner 4.
- the separator 18 is arranged between the first connector 20 and the handle 12.
- the wand 8 comprises a second connector 22 at one end of the wand 8.
- the second connector 22 connects to the first connector 20 thereby securing the wand 8 to the handheld vacuum cleaner 4 such that the handheld vacuum cleaner 4 is in fluid communication with the wand 8.
- the wand 8 comprises a third connector 24 at the end of the wand 8 opposite the second connector 20.
- the third connector 24 is connected to a fourth connector 26 provided on the cleaner head 10.
- the fourth connector 26 is substantially identical to the second connector 22, as described below. The fourth connector 26 can therefore be connected to the first connector 22 so that the cleaner head 10 can be secured directly to the handheld vacuum cleaner 4.
- Figure 2 shows the first and second connectors 20, 22 connected to each other.
- Figure 3 shows part of the cleaning apparatus 2 comprising the first connector 20.
- Figure 4 shows part of the cleaning apparatus 2 comprising the second connector 22.
- the first connector 20 is a female connector having a cylindrical receiving portion 28.
- the receiving portion 28 has a longitudinal axis which defines an engagement axis Ei of the first connector 20.
- a recess 30 is formed in a inner surface of the receiving portion 28.
- the recess 30 has a flat forward surface 32 that extends in a plane that it substantially orthogonal to the engagement axis Ei and a rearward surface 34, that is inclined from the base of the recess 30 towards the engagement axis Ei (i.e. the surface extends radially inwardly and rearwardly).
- the first connector 20 has a slot 36 formed at the end of the first connector 20.
- the second connector 22 is a male connector having a cylindrical engagement portion 38 and a collar 40.
- the engagement portion 38 is configured such that it can be inserted into the receiving portion 28 of the first connector 20.
- the engagement portion 38 has a longitudinal axis which defines an engagement axis E 2 of the second connector 22.
- the engagement axes Ei, E 2 are aligned when the second connector 22 is connected to the first connector 20.
- the engagement axes Ei, E 2 correspond to the direction along which second connector 22 is inserted into the first connector 20.
- a channel 42 extends along the engagement portion 38 in a direction which is parallel with the engagement axis E 2 .
- An elongate catch 44 is located within the channel 42 such that part of the outer surface of the catch 44 lies substantially within the same circumferential plane as the outer surface of the engagement portion 38.
- Figure 2 shows the catch 44 in a first configuration in which disengagement of the second connector 22 from the first connector 20 is prevented.
- the catch 44 is pivotally connected at one end to the engagement portion 38 by trunnions 46 (only one of which is visible in Figure 4) provided on opposite lateral sides of the catch 44, which engage respective bores 48 provided in the sides of the channel 42.
- the pivot axis X of the catch 44 extends in a direction which is substantially orthogonal to the engagement axis E 2 of the second connector 22.
- the catch 44 comprises a latching element 50 and a pressing portion 52.
- the pressing portion 52 is located towards the end of the catch 44 opposite the pivotal connection.
- the latching element 50 is located closer to the pivot axis X than the pressing portion 52. In the embodiment shown, the latching element 50 is located approximately midway between the pressing portion 52 and the pivot axis X (it will be appreciated that the latching element need not lie in the same plane as a plane passing through the pressing portion 52 and the pivot axis X).
- the latching element 50 is spaced at a distance from the engagement axis E 2 which is greater than the distance by which the pivot axis X is spaced from the engagement axis E 2 .
- the latching element 50 comprises a protrusion 54 that corresponds to the shape of the recess 30 provided on the first connector 20.
- the protrusion 54 has a leading surface 56 that is inclined with respect to the engagement axis E 2 of the second connector 22 and a trailing surface 58 that extends around the rear of the protrusion.
- the rearmost part of the trailing surface 58 extends in a plane that is substantially orthogonal to the engagement axis E 2 .
- the trailing surface 58 abuts the flat forward surface 32 of the recess 30 such that the catch 44 prevents withdrawal of the engagement portion 38 from the receiving portion 28.
- the channel 42 extends into the collar 40 such that it defines a slot 60 into which the portion of the catch 44 comprising the pressing portion 52 extends.
- At least part of the pressing portion 52 extends forward of the slot 60, and hence forward of the collar 40.
- a flange portion 62 surrounds at least part of the periphery of the pressing portion 52.
- the flange portion 62 abuts the underside of a lip 64 provided at the end of the channel 42.
- a biasing member in the form of a spring 66 is disposed between the catch 44 and the bottom of the channel 42.
- the spring 66 is disposed beneath the pressing portion 52 and is arranged to bias the pressing portion 52 away from the engagement axis E 2 such that the catch 44 is held in the first configuration in which the latching element 50 is locates in the recess 30 and the flange portion 62 is pressed against the lip 64.
- the catch 44 is then in a second configuration in which the user can slide the engagement portion 38 out from the receiving portion 28 and so disconnect the wand 8 from the vacuum cleaner 4. Because the user can simultaneously grip the end of the wand 8 and operate the catch with the same hand, the user is able to quickly and easily remove the wand 8 without having to let go of the handle 12 of the handheld vacuum cleaner 4. This greatly enhances the usability of the vacuum cleaner 4 because cleaning implements can be removed and replaced quickly and easily.
- the spring 66 urges the catch 44 back into the first configuration in which the flange portion 62 is pressed against the lip 64.
- the latching element 50 is closer to the pivot axis X than the pressing portion 52, the force required to release the catch 44 by pressing on the latching element 50 is much less than the force that would be required should the pressing portion 52 be arranged at the latching element 50. Consequently, the latching element 50 is held in engagement with the recess 30 securely, while being relatively easy to release by pressing on the pressing portion 52.
- the arrangement therefore provides a particularly secure connection between the wand 8 and the vacuum cleaner 4 which helps prevent accidental disconnection of the wand 8 from the vacuum cleaner 4. It will, however, be appreciated that it may be desirable to configure the arrangement so that the wand 8 and the vacuum cleaner 4 can be separated when a large force is applied, for example, in circumstances in which the arrangement is handled abusively, so as to avoid breaking of the apparatus.
- Figure 5 shows the first and second connectors 20, 22 separated from each other.
- the connectors 20, 22 are engaged with each other by aligning the alignment axis E 2 of the second connector 22 with the alignment axis Ei of the first connector 20, and inserting the engagement portion 38 of the second connector 22 into the receiving portion 28 of the first connector 20.
- the pressing portion 52 is aligned with the slot 36 so that, as the engagement portion 38 is inserted into the receiving portion 28, the pressing portion 52 is received by the slot 36.
- the slot 36 therefore acts as a guide for ensuring correct alignment of the connectors 20, 22.
- the leading surface 56 of the protrusion 54 rides over the front edge of the slot 36 thereby pressing the catch 44 against the spring 66 until the protrusion latches in the recess 30.
- the third connector 24 is the same as the first connector 20 and the fourth connector 26 is the same as the second connector 22. It will be appreciated that the cleaner head 10 can be removed from the wand 8 by gripping the fourth connecter 26, and pressing the catch located on the fourth connector 26, in the same manner as the wand 8 is removed from the handheld vacuum cleaner 4. Furthermore, the cleaner head 10 can be used as a cleaning implement itself by connecting the fourth connector 26 with the first connector 20 so that the cleaner head 10 is directly connected to the handheld vacuum cleaner 4.
- the cleaning implement described above comprises a wand 8 and a cleaner head 10
- the wand 8 could also be used as a cleaning implement by itself (for example to clean dirt/cobwebs from elevated areas).
- Other cleaning implements such as a flexible hose, or specialised cleaning implements for cleaning hard floors, soft furnishings, specific types of carpets or crevices could comprise a connector which is the same as the second and fourth connectors 22, 26 and so could be connected to the wand 8 or the vacuum cleaner 4 respectively.
- the connector arrangement is particularly advantageous for handheld vacuum cleaners, it will be appreciated that the connector arrangement would be suitable for other types of vacuum cleaner including, but not limited to, cylinder vacuum cleaners and upright vacuum cleaners, including lightweight stick vacuum cleaners, in which cleaning implements, such as cleaner heads, are interchanged.
