Definitions
- the present invention relates to a vacuum cleaner, more particularly, a stick vacuum cleaner which may be converted to a handheld vacuum cleaner without separating and storing parts of said stick vacuum cleaner.
- the stick vacuum cleaner of the present invention is also known or designated as an upright vacuum cleaner by some of its users.
- the handheld mode of the invention is known or designated as car vacuum cleaner.
- Stick vacuum cleaners are widely known for many years. These vacuum cleaners typically have a body mounted on a rigid tube and standing on top of a floor nozzle. The body typically accommodates a vacuum motor, a filter and other electric parts mounted on the rigid tube on top of which a handle is attached. As the body comprises most essential parts of a vacuum cleaner, the body may be converted to a handheld, or as some say, car type vacuum cleaner firstly by removing the floor nozzle and the rigid tube away from the body.

Fig. 1 . The side and frontal views of the same stick vacuum cleaner (1) are depicted, respectively, inFigs 2A and 2B . The stick vacuum cleaner (1) generally comprises a hand unit (5) as the main body of the stick vacuum cleaner (1) and a tube (22) which may be telescopically inserted in the body of said hand unit (5). The vacuum cleaner is further equipped with a floor nozzle (18) which is fixed to the front end of the hand unit (5). The first end of the tube (22) is attached, via a pivotal joint (14), to a collapsible extension piece (12). - The hand unit (5) forms the main body of the stick vacuum cleaner (1). It comprises a vacuum motor (30) and a filter (31) for protecting the vacuum motor (30) from particles found in the soiled air sucked into the body of the hand unit (5). While the hand unit (5) illustrated in the accompanying drawings is energized via the mains supply it may have its own power source, such as rechargeable batteries. The hand unit (5) has a suction slot (15) located in the front end of the hand unit. The suction slot (15) is shaped and dimensioned to accommodate the connection pipe (20) of the floor nozzle (18). The connection pipe (20) of the floor nozzle (18) sealingly conveys the soiled air sucked from the floor to the inside of the hand unit (5). Dust and particles found in the soiled air are filtered by the filter (31) and are collected, by gravitational forces, in the accumulation volume (28) formed around the cylindrical collection pipe (27) as depicted in
Fig. 7A . - The hand unit (5) comprises a handle (25) on its rear part for facilitating use of the same. Both of the hand unit (5) and the handle (25) have a tube seat (24) for accommodating the rigid tube (22). The tube may be made of metals or plastics for carrying the stick vacuum cleaner (1). The tube seat (24) formed in the body of the hand unit (5) and in the handle (25) is in the form of a tubular channel which is sized and shaped to accommodate the tube (22). The tube (22) is telescopically movable within the tube seat (24) by the user. While the tube (22) may be hollow, it may be circular, oval or polygonal in cross section. The length (L) of tube seat (24) formed in the body of the hand unit (5) and in the handle (25) is substantially equal to the length of the tube (22). This latter means that the substantial amount of the tube (22) may be inserted via a telescopic movement in the tube seat (24) formed in the body of the hand unit (5) and also in the handle (25).
- If a user wishes to use the stick vacuum cleaner (1) in the upright mode, the tube (22) shall be in the extracted position as shown in
Figs. 2A and 2B . If however the use wishes to use the vacuum cleaner in the handheld mode, the user shall slidably insert the tube (22) in the tube seat (24) formed on the body of the hand unit (5) and the handle (25). In such cases, removal of the floor nozzle (18) is sufficient for putting the cleaner (1) in the car cleaner mode. The car cleaner mode is depicted inFigs. 7A-7B-7C andFig. 8 . - The tube (22) of the stick vacuum cleaner (1) is not straight and is arc shaped. It has a length (L) and thickness (t) as shown in
Figs. 10A to 10D . Based on the fact that the tube (22) is arc shaped, the tube has a peak height (k) which is larger than its thickness (t) as shown inFig. 10A to 10D . The value of the peak height (k) is normally at least 30% more than the value of the thickness (t) of the tube. The diameter (Φ) of the arc of the tube (22) is in the range of 5 to 10 times the length (L) of the tube (22). Likewise, the tube seat (24) formed on the body of the hand unit (5) and the handle (25) essentially has the same geometry. The diameter (Φ) of the arc of the tube (22) is equal to the diameter (Φ) of the arc of the tube seat (24) formed on the body of the hand unit (5) and the handle (25). This enables that the tube (22) can be smoothly moved telescopically within the tube seat (24). - The tube (22) of the stick vacuum cleaner (1) is made arc shaped for the purpose that parts which substantially add to the weight of the hand unit (5) are contained on the inner side of the arc, such that the center of gravity of the stick vacuum cleaner (1) substantially coincides with the central point of the floor nozzle (18). This enables that the stick vacuum cleaner (1) can stand upright in the absence of interference from a user. The inner side of the arc means parts which remain in between the arc and the center of the arc. The center of gravity (C.G.) of the hand unit (5) is illustrated with an arrow in broken lines in
Figs. 2A and 2B . An example of these parts that add much to the overall weight of the hand unit (5) is the vacuum motor (30). The arc shaped geometry of the tube (22) helps to keep the center of gravity (C.G.) of the stick vacuum cleaner (1) coincide with the central point of the floor nozzle (18). In this case, the stick vacuum cleaner (1) itself stands upright and does not have to lean on a furniture in the cleaning room. - The stick vacuum cleaner (1) is shown in use mode in
Figs. 2A and 2B . In this position, the tube (22) is in its extracted position and remains only partly in the handle (25) of the hand unit (5).

Floor nozzle (18) is yet not dismantled. -
Fig. 5 shows the hand unit (5) in a state where the floor nozzle (18) is dismantled. The connection in between the floor nozzle and the hand unit (5) is established with a connection pipe (20) which enters smoothly in the suction slot (15) found in the front end of the hand unit (5).Fig. 6A to 6C show the process of conversion from a stick vacuum cleaner (1) to a hand or car cleaner.Figs. 7A to 7C andFig. 8 show the hand unit (5) where the collapsible extension piece (12) is folded on top of a corresponding protrusion (32) on the body of the hand unit (5). The collapsible extension piece (12) is pivotably connected to the handle (25) via a pivotal joint (14). Once the collapsible extension piece (12) is folded on top of the corresponding protrusion (32), the vacancy under the handle (25) becomes a closed geometry for facilitating handling of the hand unit (5). - The body of the hand unit (5) is further equipped with a tube seat lock button (34) for allowing or blocking telescopic movement of the tube (22) within the tube seat (24). The tube seat lock button (34) engages with a plurality of grooves (37) formed on the tube (22).
