Definitions

  • the invention relates to an attachment for a cleaning appliance particularly, but not exclusively, for a vacuum cleaner.
  • Vacuum cleaners are frequently sold with a range of attachments for different cleaning purposes. These attachments are usually fitted onto the end of a wand or hose of an upright or cylinder vacuum cleaner.
  • a vacuum cleaner may be provided with a brush tool for dusting surfaces, a stair tool for cleaning stairs, and a crevice tool for cleaning hard-to-reach areas which are difficult to access with larger attachments.
  • a suction opening of an attachment is close to, or in contact with, a surface to be cleaned.
  • the whole of the suction opening should be in close proximity to the surface to be cleaned. If there is too great an air gap between the suction opening of the attachment and the surface to be cleaned, the air gap will act as an air bleed and less of the air entering the suction opening will have passed across or through the surface to be cleaned. Therefore, less dirt and dust will be picked up and the cleaning performance of the vacuum cleaner will be reduced.
  • the wand or hose of the vacuum cleaner to which the attachment is connected must often be held at a particular angle. Therefore, there may be some surfaces which are orientated or positioned such that they either cannot be cleaned effectively or can only be cleaned with great difficulty using a conventional attachment. This is because the user may not be able to hold the wand or hose at the required angle in order to clean these surfaces. For example, the tops of doors, shelves or cabinets are particularly problematic due to their location at a high level relative to the user.
  • an attachment for a vacuum cleaner such as a stair tool or a brush tool is often provided with a rotatable connection located between the head of the tool and the connection part of the tool (which connects to the mouth of a wand or hose).
  • the rotatable connection may be angled relative to the head or the connection part such that different angular orientations of the head with respect to the wand or hose can be achieved. This allows a user to clean more easily surfaces orientated or positioned awkwardly.
  • a disadvantage of the above type of attachment is that a single rotatable connection only allows a limited range of angular positions of the head of the attachment relative to the wand or hose.
  • a high level for example the tops of shelving units, cupboards or light fittings
  • the limited range of movement of the head of the attachment will mean that the wand or hose of the appliance must be held at an awkward angle in order to clean effectively. This is undesirable because it may be uncomfortable for a user to hold, or may result in some surfaces being impossible to clean.
  • U.S. Pat. No. 1,658,311 discloses a vacuum cleaner attachment which comprises two perpendicular elbow joints connected by a plurality of coupling nuts.
  • JP 2003-000483 discloses a vacuum cleaner attachment which comprises a square nozzle and a rear pipe which are connected together by a movable joint.
  • the joint comprises a pair of parallel pivotable connections.
  • the pivotable connections pivot the square nozzle up and down relative to the connecting portion.
  • the rotatable connections or pivots of the above-described attachments only allow movement of the respective nozzles in planes perpendicular to or parallel to the handle member or rear pipe of the respective attachments. This limits the range of potential orientations of the nozzle with respect to the handle.
  • the invention provides an attachment for a cleaning appliance comprising a head and a neck, the head including a suction opening that lies in a suction plane, the neck including an intermediate portion and an end portion for connection to the mouth of a wand or hose, the end portion having a longitudinal axis, the attachment further comprising a first rotatable connection located between the end portion and the intermediate portion having a first axis of rotation, and a second rotatable connection located between the head and the intermediate portion having a second axis of rotation, each rotatable connection allowing relative movement of the end portion with respect to the head, wherein the first axis of rotation is inclined with respect to the longitudinal axis of the end portion, and the second axis of rotation is inclined with respect to the suction plane.
  • the head of the attachment can be moved into a variety of useful positions to allow easier cleaning of walls and high-level horizontal surfaces.
  • the head may be positioned in a wide range of angular orientations relative to the wand or hose such that a user can select the most appropriate orientation for the cleaning task in hand.
  • the second axis of rotation is inclined to the suction plane at an angle in the range of 20° to 70°.
  • the first axis of rotation is at an angle to the second axis of rotation. This permits an even greater range of movement of the head with respect to the end portion. More preferably, the first axis of rotation is at an angle in the range of 80° to 1300 to the second axis of rotation. This range of angles has been shown by empirical analysis to produce the most useful range of positions of the head of the attachment whilst still allowing a compact, easy to manufacture attachment.
  • the sum of the angle between the first axis of rotation and the longitudinal axis and the angle between the second axis of rotation and the suction plane is in the range of 40° to 130°. This combination of angles produces the most useful range of positions of the head of the attachment.
