Description
- This invention relates to a Vacuum Cleaner particularly, to a cylinder-type vacuum cleaner which is designed for stable, safe and easy use on both a flight of stairs and also on a flat surface such as a floor.
- There are very few prior art machines which have been designed for use on stairs. Those that have, embody awkward and cumbersome mechanisms which protrude to engage with the stairs or body parts which engage with the stair step and depend on the body of the vacuum cleaner being precisely positioned at a particular angle so as to allow the body of the vacuum cleaner to engage with the stairs in order to prevent the Vacuum Cleaner from slipping back down the stair case. In
US2005/0015917 a conventional vacuum cleaner according to the preamble of independent claim 1 is disclosed,. - None of these prior art vacuum cleaners are designed or intended to be moved up or down a flight of stairs other than by the user lifting the entire vacuum cleaner and repositioning it on another part of the flight of stairs. This results in a cumbersome manoeuvre. It would be far more convenient if the vacuum cleaner could be pulled up the flight of stairs in a smooth continuous movement by dragging or sliding the body of the vacuum cleaner. The configuration of prior art vacuum cleaners is such that dragging or sliding the machine is difficult and awkward. No Prior art machines are designed in such a way so as to span across two or more stair-treads in order to provide increased stability and also facilitate smooth ascent of the stair case.
- Further to this, no prior art machines which are intended to overcome the problems associated with use on a stair case, are configured so that the centre of gravity of the machine creates its' own inherent stability or have a curved undercarriage which is specifically designed to aid movement of the vacuum cleaner up a flight of stairs and yet still allow conventional use of the machine on a flat surface such as a floor. Nor do any prior art machines implement rotating ground engaging members that can be engaged or disengaged to allow movement in one direction only, in order to act as a break against slipping downstairs. No prior art machines which are intended to overcome the problems associated with use on a stair case, are configured so that rotating members incorporated into the front of the vacuum cleaner will allow the nose to ascend a step with very little resistance or have any combination of any of these features which would make them suited for us on a stair case, while retaining the ability to be used on a flat floor.

This object is achieved by a vacuum cleaner as defined by independent claim 1, by i.a. means of the shape of the curved undercarriage, which provides stability by traversing two treads and also because of a switchable ratchet mechanism which when disengaged, allows rotation of the ground engaging members in a forward or backward direction to allow easy manoeuvring on floors but when applied, allows the rotating ground engaging members to travel in a forward direction only, for use on stairs and thus overcoming the previous difficulties of using the same vacuum cleaner on both the floor and the stairs.

The rotating ground engaging members that engage with the stair tread can be acted upon by the locking mechanism that prevents the vacuum cleaner descending backwards down the stairs and the centre of gravity created by the location of the motor is such that it adds inherent stability when being used on stairs.

The specifically curved shape of the undercarriage of the vacuum cleaner allows it to sit in a very stable position by spanning two, or in the case of large versions more than two, stair treads.
- One or more multi-directional, rotating ground engaging members may be located at the front part of the Vacuum Cleaner. The castor is the preferred choice of multi-directional, rotating ground engaging member for this position but should not be regarded as limiting to the present invention. This member allows maximum manoeuvrability and stability of the Vacuum Cleaner when used on a flat surface such as a floor in the conventional sense as well as providing manoeuvrability and stability when used on a stair case or flight of stairs.
- In an alternative embodiment, more than one rotating ground engaging members may be used at the front of the vacuum cleaner.
- The locking mechanism which is intended to be applied to the rear rotating ground engaging members, is constructed in a manner which allows each rotating ground engaging member to be engaged or disengaged individually by means of the mechanism actuator being built into each individual rotating ground engaging member or alternatively it can be applied to one or more rotating ground engaging members simultaneously by means of the mechanism actuator being built into the body of the Vacuum Cleaner in order to act on either one or more of the rotating ground engaging members or the axle or axles of the rotating ground engaging members.
- The handle on the front of the vacuum cleaner may be orientated in a plane which runs from front to back and may also be orientated at alternative angles to that, at the point of manufacture. The handle can also be built into the Vacuum Cleaner in the form of a countersunk grip. These are preferable features but should not be regarded as limiting to the present invention.
- One or more rotating members which are not floor engaging members, may be located on the furthest forward point or 'nose' of the front end of the Vacuum Cleaner in order to assist the Vacuum Cleaner to ascend a step with the minimum of resistance.
- In an alternative embodyment, one or more rotating members which can engage with a stair case may also be encorporated into the curved undercarriage.
- When the vacuum cleaner is to be used on a flat surface such as a floor, the locking mechanism should be disengaged in order to allow free movement in more than one direction, of the vacuum cleaner which can then be manoeuvred or positioned by pulling the suction hose, "wand" or the handle.
- When the vacuum cleaner is to be used on a stairs, the locking mechanism should be engaged in order to allow rotation of the ground engaging members, in a forward direction only and thus permitting only forward movement of the vacuum cleaner.
- In order to traverse the stair risers, the user pulls the suction hose forward and upwards, until the curved shape of the undercarriage of the vacuum cleaner clears the next step up or until the stair riser engaging member engages with the riser of the stair case in front of the vacuum cleaner and that continues up and onto the next step. The curved shape of the undercarriage of the vacuum cleaner and the provision of the stair riser engaging member, assist in the vacuum cleaner's ascent of the stair tread.
- The rotating ground engaging members, having been engaged in a locked position by the actuator, allow only forward movement of the vacuum cleaner and the centre of gravity of the vacuum cleaner specifically aided by the position of the motor, also assists in the rising of the front of the vacuum cleaner to climb the stair tread without resulting in instability or tipping of the vacuum cleaner.
