DETAILED DESCRIPTION OF THE INVENTION
[0059] An embodiment of an attachment for a vacuum cleaning appliance will be described with reference to FIGS. 1 to 20(b). In this embodiment, the attachment is in the form of a two-part wand assembly 10. With reference first to FIG. 1, the wand assembly 10 comprises a first part 12 which attaches the wand assembly 10 to a main body 14 of the vacuum cleaning appliance 16. As is well known, the main body 14 comprises a suction source 18 for generating an airflow through the appliance 16, a separation system 20 for separating dirt and other debris from the airflow, a power source 22 for driving various components of the appliance 16, including the suction source 18, and an air outlet 24.
[0060] The wand assembly 10 further comprises a second part 26 connected to the first part 12. A floor tool 28 is connected to a lower end section of the second part 26. A dirt-bearing airflow is drawn into the appliance 16 through the floor tool 28. As illustrated in FIG. 1, the appliance 16 may be a handheld vacuum cleaning appliance, in which case the wand assembly 10 is connected directly to the main body 14. Alternatively, the appliance may be a cylinder vacuum cleaning appliance, in which case the wand assembly 10 is disposed between the floor tool 28 and a hose for conveying the dirt-bearing airflow from the wand assembly 10 to the main body 14.
[0061] The first part 12 of the wand assembly 10 is illustrated in more detail in FIGS. 2(a) to 8(d). The first part 12 of the wand assembly 10 comprises a crevice tool, having a main body defining a crevice nozzle 30 having a front section 31, an air inlet 32 located at a front end of the front section 31, and air bleeds 34 located on a side surface of the front section 31. The main body includes a tubular rear section 36 which is inserted into the main body 14 of the appliance 16. The rear section 36 includes a manual release catch 38 for releasably connecting the first part 12 to the main body 14 of the appliance 16 as the rear section 36 is inserted into the main body 14, a pair of guide rails 40 for aligning the first part 12 with the main body 14 as the rear section 36 is inserted into the main body 14, and an air outlet 42 from which air enters the main body 14 from the wand assembly 10. The connector 38 is depressed by a user to release the first part 12 from the main body 14, and is biased by a spring (not shown) towards the raised position illustrated in the figures for retaining the first part 12 within the main body 14.
[0062] The first part 12 of the wand assembly 10 also includes a brush section 44. As described in more detail below, the brush section 44 is moveable relative to the crevice nozzle 30 between a retracted position, as illustrated in FIGS. 2(a) to 3(c), and a deployed position, as illustrated in FIGS. 5(a) to 8(d). The brush section 44 comprises a set of bristles 46 mounted on a brush collar 48. The bristles 46 are arranged such that they are substantially parallel, and such that the bristles 46 extend in a direction which is substantially parallel to the longitudinal axis of the crevice nozzle 30. With reference also to FIG. 8(a), the brush collar 48 extends at least partially about the crevice nozzle 30. In this embodiment the brush collar 48 surrounds the crevice nozzle 30. The bristles 46 are arranged in an array which extends partially about the crevice nozzle 30, preferably by an angle which is between 180 and 360°, and which is preferably less than 270°. In this embodiment, the array of bristles 46 extends about the crevice nozzle 30 by an angle of approximately 250°.
[0063] By way of example, the bristles 46 may be formed from nylon or carbon fibre, and the brush collar 48 may be formed from plastics material. The bristles 46 may be attached to the brush collar 48 using an over-moulding technique. In this embodiment, the bristles 46 are arranged in a plurality of bristle tufts spaced about the brush collar 48.
[0064] The brush section 44 also includes a brush cover 50 which extends partially about the brush collar 48, and a bristle sleeve 52 which extends about the array of bristles 46. The bristle sleeve 52 has one end sandwiched between the brush collar 48 and the brush cover 50, and a free end located adjacent to the free ends of the bristles 46.
[0065] The bristle sleeve 52 is provided to minimise outward bending, or splaying, of the bristles 46 both during use of the brush section 44 by a user, or, as described in more detail below, as the second part 26 of the wand assembly 10 is pushed over the first part 12 during assembly. The bristle sleeve 52 is arranged such that the free ends of the bristles 46 protrude outwardly beyond the free end of the bristle sleeve 52. Preferably, no more than 20% of the length of the bristles 46, more preferably no more than 10% of the length of the bristles 46, protrudes beyond the free end of the bristle sleeve 52. The bristle sleeve 52 is positioned in close proximity to the external side surfaces of the bristles 46, preferably within 5 mm of the external side surfaces of the bristles 46. The bristle sleeve 52 is preferably formed from a flexible material, and in this embodiment is formed from a polyurethane plastics material, such as thermoplastic polyurethane (TPU).
[0066] FIGS. 2(a) to 3(c) illustrate the brush section 44 in a retracted position relative to the crevice nozzle 30. In its retracted position, the brush section 44 is located adjacent the rear section 36 of the crevice nozzle 30, with the brush cover 50 abutting a housing 54 for the catch 38 for connecting the first part 12 to the main body 14 of the appliance 16. This enables the first part 12 of the wand assembly 10 to be used in a “crevice mode”, in which the crevice nozzle 30 is inserted between gaps in furniture and the like during cleaning. To move the brush section 44 towards its deployed position, as illustrated in FIGS. 5(a) to 8(d), the user grips the brush cover 50 and pulls the brush section 44 along the crevice nozzle 30 towards its deployed position.
[0067] The first part 12 includes guide mechanisms for guiding the movement of the brush section 44 relative to the crevice nozzle 30. These mechanisms ensure that the brush section 44 moves linearly along the crevice nozzle 30 as it moves between its retracted position and its deployed position. As described in more detail below, the first part 12 includes two guide mechanisms for guiding the movement of the brush section 44 relative to the crevice nozzle 30. With reference also to FIGS. 4(a) and 8(b), a first guide mechanism comprises a pair of parallel rails 56 located on opposite sides of the crevice nozzle 30 and extending parallel to the longitudinal axis of the first part 12, and a pair of parallel channels 58 formed on the brush collar 48 for receiving the rails 56. The rails 56 extend from the rear section 36 of the crevice nozzle 30, and terminate at free ends 60 located partway along the crevice nozzle 30. With reference to FIGS. 2(a) to 3(c) and 4(c), the second guide mechanism comprises a channel 62 extending linearly along the upper surface of the crevice nozzle 30, parallel to the longitudinal axis of the first part. The channel 62 begins at a position which is both axially and angularly spaced from the free ends of the rails 56, and terminates adjacent to the air inlet 32. The second guide mechanism further comprises a pawl 64 connected to the brush cover 50 for pivoting movement relative thereto, and which is biased by a spring 66 against the upper surface of the crevice nozzle 30. The pawl 64 is positioned so that it enters the channel 62 as the brush section 44 moves towards its deployed position, and preferably before the channels 58 of the brush collar 48 become fully disengaged from the rails 56 of the crevice nozzle 30.
[0068] With reference also to FIG. 4(b), the axial spacing of the channel 62 from the rails 56 defines a tubular section 68 of the crevice nozzle 30 which is located between the rails 56 and the channel 62. The tubular section 68 has a substantially circular outer profile. As discussed in more detail below, the external surface of the tubular section 68 of the crevice nozzle 30 provides an annular mating surface for engaging a seal of the second part 26 of the wand assembly 10 to inhibit the leakage of air from between the first part 12 and the second part 26 of the assembled wand assembly 10.
[0069] Returning to FIGS. 5(a) to 8(d), in the deployed position of the brush section 44 the pawl 64 is located at the end of the channel 62 located adjacent to the air inlet 32, and the bristles 46 are located beyond the air inlet 32 of the crevice nozzle 30. This enables the first part 12 of the wand assembly 10 to be used in a “brush mode” in which the bristles 46 can agitate dust and debris from exposed surfaces of furniture and household items, for example, during cleaning to become entrained in the airflow entering the crevice nozzle 30 through the air inlet 32.
[0070] The brush section 44 includes a mechanism for retaining the brush section 44 in its deployed position. This prevents the brush section 44 from moving relative to the crevice nozzle 30 during use of the first part 12 in its brush mode. The retaining mechanism comprises a pair of retention catches in the form of fingers 70, 72 which are carried by the brush section 44. With reference to FIG. 8(b), each finger has a base 74 and a tip 76. Each finger 70, 72 is biased by a respective spring (not shown) for movement relative to the crevice nozzle 30 in such a direction that urges its tip 76 against the external surface of the crevice nozzle 30. At the deployed position of the brush section 44, under the action of the biasing springs the tip 76 of each finger 70, 72 enters a respective recess 78, 80 located on the external surface of the crevice nozzle 30. The engagement between the fingers 70, 72 and the recesses 78, 80 serves to retain the brush section 44 in its deployed position.
[0071] As the fingers 70, 72 move relative to the crevice nozzle 30 to retain the brush section 44 in its deployed position, the bases 74 of the fingers 70, 72 protrude outwardly from respective apertures formed in the brush cover 50, as illustrated in FIGS. 5(a) to 8(b). With reference to FIGS. 8(c) and 8(d), to release the brush section 44 from its deployed position, a user manually squeezes the bases 74 of the fingers 70, 72 to urge the tips 76 of the fingers 70, 72 out from the recesses 78, 80. The user may then simultaneously move the brush section 44 towards its retracted position. As illustrated in FIGS. 2(a) to 3(c), when the brush section 44 is positioned remote from the deployed position, the bases 74 of the fingers 70, 72 are retracted so as to not protrude from the apertures formed in the brush cover 50.
[0072] The second part 26 of the wand assembly 10 will now be described with reference to FIGS. 9(a) to 10(c). The second part 26 comprises a suction inlet 88 located at the lower end section of a wand. The wand comprises an outer tube 90 extending about an inner tube 92 which conveys the airflow from the floor tool 28 towards the main body 14 of the appliance 16. Wires 94 for supplying power to the floor tool 28 are housed between the outer tube 90 and the inner tube 92, and terminate at connector pins 96 located at the upper end of the second part 26.
[0073] An upper section of second part 26 includes a neck 98 for receiving the first part 12 of the wand assembly 10. The neck 98 comprises a neck body 100 which is connected to the inner tube 92, and a neck cover 102 which extends about the neck body 100 and is connected to the outer tube 90. As described in more detail below, the neck body 100 and neck cover 102 are shaped to house the first part 12 of the wand assembly 10 when the first part 12 and the second part 26 are connected together. At least part of the neck cover 102 may be formed from transparent material to enable the first part 12 to be visible to a user when the first part 12 and the second part 26 are connected together. This can provide a visual reminder to the user of the presence of the crevice tool stored within the neck 98.
[0074] The second part 26 of the wand assembly 10 includes a sealing mechanism for engaging the annular mating surface of the tubular section 68 of the crevice nozzle 30. The sealing mechanism comprises a seal 104 which is in the form of a flexible tube preferably formed from rubber or other elastomeric material. The one end of the seal 104 is connected to a first end of an annular seal carriage 106, preferably using an over-moulding process, whereas the free end of the seal 104 is retained within an annular housing 108 defined by the neck body 100. The second end of the seal carriage 106 is engaged by a first end of an annular wedge 110 which is moveable axially within and relative to the neck body 100. The wedge 110 is retained within the neck body 100 by wedge holder 112 which partially extends about the wedge 110. Wall 114 of the neck body 100 provides an end stop for restricting the movement of the wedge 110 towards the upper open end 116 of the second part 26 due to relaxation of the seal 104.
[0075] The connection of the first part 12 to the second part 26 of the wand assembly 10 will be described with reference to FIGS. 11(a) to 12(d). With the brush section 44 of the first part 12 in its retracted position, the crevice nozzle 30 is inserted through the upper open end 116 of the second part 26. Returning to FIG. 10(c), the neck 98 comprises a relatively wide internal section 117a for housing the rear section 36 and the brush section 44 of the first part 12, and a relatively narrow internal section 117b for receiving the front section 31 of the first part 12. The inner surface of the neck body 100 includes a pair of grooves 118 for receiving the rails 56 located on the external surface of the crevice nozzle 30. This ensures that the second part 26 is accurately angularly aligned with the first part 12 as it is pushed over the first part 12.
[0076] The second part 26 is pushed over the first part 12 until the end 120 of the crevice nozzle 30 engages an end stop 122 defined by the relatively narrow internal section 117b of the neck body 100. To connect the first part 12 to the second part 26, the second part 26 comprises a catch 124 which is biased by a spring (not shown) to engage the upper surface of the crevice nozzle 30 as it is inserted into the second part 26. As illustrated in FIGS. 12(c) and 12(d), when the first part 12 has been fully inserted into the second part 26 end portions 126 of the catch 124 enter a pair of recesses 128 located on the upper surface of the crevice nozzle 30. This prevents the first part 12 and the second part 26 from being accidentally pulled apart during use of the wand assembly 10.
[0077] As the first part 12 becomes fully inserted into the second part 26, the ends 60 of the rails 56 engage the wedge 110 and push the wedge 110 against the seal carriage 106. This causes the seal carriage 106 to move towards the housing 108, which in turn causes the seal 104 to deform and engage the annular mating surface defined by the tubular section 68 of the crevice nozzle 30. This causes an air tight seal to be formed between the crevice nozzle 30 and the neck body 100, and thus between the first part 12 and the second part 26 of the wand assembly 10.
[0078] As illustrated in FIGS. 11(a) to 12(d), when the first part 12 is connected to the second part 26 of the wand assembly 10, both the crevice nozzle 30 and the brush section 44 of the first part 12 are housed within the second part 26. This inhibits damage to the brush section 44 during use of the wand assembly 10 to clean a floor surface, for example, as illustrated in FIG. 1.
[0079] To disconnect the second part 26 from the first part 12, the user depresses the catch 124 to move the end portions 126 of the catch 124 out from the recesses 128, and, simultaneously, pulls the second part 26 from the first part 12. With particular reference to FIGS. 17(b) and 17(c), the neck cover 102 is shaped to form an interference fit with the brush cover 50. The mechanical interaction between the brush cover 50 and the neck 98 serves to retain the brush section 44 in a static position within the neck 98 as the crevice nozzle 30 starts to be withdrawn from the second part 26, as illustrated in FIGS. 13(a) to 14(d). As a result, the withdrawal of the first part 12 from the second part 26 effects movement of the brush section 44 relative to the crevice nozzle 30 towards its deployed position.
[0080] FIGS. 15(a) to 17(c) illustrate the wand assembly 10 with the first part 12 almost fully withdrawn from the second part 26. In the configuration illustrated in these figures, the crevice nozzle 30 has been withdrawn from the second part 26 to such an extent that the brush section 44 has moved relative to the crevice nozzle 30 to its deployed position. As shown most clearly in FIG. 16(c), with the brush section 44 in its deployed position the pawl 64 is located at the end of the channel 62 proximate to the end of the crevice nozzle 30, and is urged against the end of the channel 62 by the spring 66. This inhibits movement of the brush section 44 beyond its deployed position. Consequently, any further movement of the crevice nozzle 30 out from the second part 26 of the wand assembly 10 will cause the brush section 44 to move with the crevice nozzle 30 relative to the neck 98. As a result, whilst having been first inserted into the second part 26 with the brush section 44 in its retracted position, the first part 12 is subsequently withdrawn from the second part 26 with the brush section 44 in its deployed position.
[0081] As the brush section 44 is pulled from the second part 26 of the wand assembly 10, the brush section 44 becomes released from the neck 98. This allows the fingers 70, 72 to move relative to the crevice nozzle 30, under the action of the biasing springs, from the position illustrated in FIG. 17(b) to the position illustrated in FIG. 8(b). The ends 76 of the fingers 70, 72 enter the recesses 78, 80 to retain the brush section 44 in its deployed position.
[0082] The first part 12 may also be inserted into the second part 26 of the wand assembly 10 with the brush section 44 in its deployed position. In this case, as the first part 12 is inserted into the second part 26 the free ends of the bristles 46 and the bristle sleeve 52 engage an inclined wall 130 of the neck body 100 to inhibit movement of the brush section 44 within the neck body 100 beyond the position illustrated in FIGS. 15(a) to 17(c). As discussed above, in this position the neck 98 forms an interference fit with the brush cover 50, and serves to move the bases 74 of the fingers 70, 72 inwardly to release the brush section 44 from its deployed position. The crevice nozzle 30 may then be further inserted into the second part 26 of the wand assembly 10, as illustrated in FIGS. 13(a) to 14(d), whilst the brush section 44 remains stationary within the neck 98 in the position illustrated in FIGS. 15(a) to 17(c). With further pushing of the crevice nozzle 30 into the second part 26, the catch 124 enters the recesses 128 of the crevice nozzle 30 to connect the first part 12 to the second part 26, as illustrated in FIGS. 11(a) to 12(d).
[0083] In use, the assembled wand assembly 10 may be connected to the main body 14 of a vacuum cleaning appliance 16 and to a floor tool 28, as illustrated in FIG. 18(a), for floor cleaning. The first part 12 of the wand assembly 10 is connected to the main body 14, the second part 26 of the wand assembly 26 is connected to the first part 12, and a floor tool 28 is connected to the second part 26. An airflow generated by the suction source 18 of the appliance 16 enters the appliance 16 through the floor tool, and passes through the wand assembly 10 to the main body 14 of the appliance 16. Within the wand assembly 10, the airflow passes through the inner tube 92 and is conveyed into the crevice nozzle 30 by the neck body 100. The seal 104 inhibits the leakage of air from between the crevice nozzle 30 and the neck body 100. The airflow flows through the crevice nozzle 30 to enter the main body 14 of the appliance 10.
[0084] To use the appliance 16 in a handheld mode of operation for cleaning furniture and the like, the user depresses catch 124 to disengage the end portions 126 of the catch 124 from the recesses 128 to release the second part 26 from the first part 12. Simultaneously, the user pulls the second part 26 away from the first part 12, as shown sequentially in FIGS. 18(b) and 18(c), until the second part 26 has become detached from the first part, as illustrated in FIG. 19 (the user may release the catch 124 as soon as the end portions 126 of the catch 124 have become axially spaced from the recesses 128). This enables the appliance 16 to be used in a handheld mode to clean items above a floor surface. With the brush section 44 in its deployed position, the appliance 16 may be used in a brush mode, in which the bristles 46 agitate dust from the surfaces of furniture, ornaments or the like to become entrained within the airflow entering the first part 12 of the wand assembly 10. To move the brush section 44 to its retracted position, as illustrated sequentially in FIGS. 20(a) and 20(b), the user squeezes together the bases 74 of the fingers 70, 72 and pushes the brush section 44 along the crevice nozzle 30 to its retracted position.
