[0006] In the state of the art European Patent Application No EP0887040, a vacuum cleaner is explained wherein vacuum cleaner body is detachably fastened to the support pipe, and is made to run by the wheels of the suction device in a condition where the vacuum cleaner body is attached to the support pipe.

[0007] The aim of the present invention is the realization of a vacuum cleaner that can be carried easily. [0008] The vacuum cleaner realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, comprises a locking mechanism having parts disposed oppositely, one part on the nozzle that moves with respect to the pipe, and the other part on the body, providing to attach the nozzle to the body, for carrying the body by pulling on wheels without lifting up.

[0009] In an embodiment of the present invention, the nozzle enters into the space between the body and the floor, without requiring to change the position of the body during cleaning and the vacuum cleaner can be dragged along on wheels, pulling with the help of the handle by attaching the body and the nozzle to each other by means of the locking mechanism.

[0010] Furthermore, attaching the body not to the pipe but to the nozzle, being rotatable within certain angles, that is secured to the pipe, allows the user who is pulling from the handle to move the body more easily for maneuvering.

[0011] In another embodiment of the present invention, the locking mechanism comprises a housing and a protrusion that is locked by fitting into this housing, disposed oppositely on the body and the nozzle.

[0012] In another embodiment of the present invention, the locking mechanism comprises a slide and a rail disposed oppositely on the body and the nozzle. This embodiment of the present invention maintains the nozzle to be more easily attached to the base of the body.

[0013] In another embodiment of the present invention, the portion of the body wherein the nozzle enters between itself and the floor is inclined. Thus the user can easily place the nozzle between the body and the floor while standing up. This provides for the nozzle and the body to be fitted and locked to each other more easily.

[0014] In another embodiment of the present invention, the locking mechanism is arranged on platform that can rotate around its axis. Thus the maneuvering capability of the vacuum cleaner while being pulled is further enhanced.

[0015] By means of the present invention the vacuum cleaner can be carried by dragging on the wheels.

[0023] The vacuum cleaner (1) of the present invention comprises a body (2), a preferably resilient hose (3) attached to the body (2) from one end, a handle (5) attached to the other end of the hose (3), a pipe connected to the handle (5) and a nozzle (6) fitted on the end portion of the pipe (4) for cleaning the carpet and/or the floor (Figure 1).

[0024] The vacuum cleaner (1) comprises one or more wheels disposed on the body (2) and the nozzle (6).

[0025] The vacuum cleaner (1) comprises a connector element (10) between the nozzle (6) and the pipe (4) that facilitates the attachment of the nozzle (6) to the end of the pipe (4). The nozzle (6) is movably mounted to the pipe (4) by means of the connector element (10). The user can easily perform the cleaning process with the nozzle (6) that can move with respect to the pipe (4). Moreover, movably attaching the nozzle (6) to the pipe (4) provides the handle (4) and the pipe (4) to change the distance and the angle there between the floor and inserting the nozzle (6) under the furniture for reaching to clean the unreachable regions with the nozzle (6).

[0026] The vacuum cleaner (1) furthermore comprises a locking mechanism (7) for carrying thereof on wheels by pulling, with one part disposed on the nozzle (6) that moves with respect to the pipe (4), and the other part on the body (2) for mounting the nozzle (6) to the body (2) and to be locked to the body (2). Accordingly, the vacuum cleaner (1) can be carried on wheels by pulling.

[0027] In this embodiment of the present invention, the position of the body (2) during cleaning is not changed. The nozzle (6) and the body (2) are fitted to each other and locked by means of the locking mechanism (7) on the nozzle (6) and on the body (2) by pushing the nozzle (6). Thus the vacuum cleaner (1) can be pulled to be dragged on the wheels.

[0028] In an embodiment of the present invention, the body (2) has a shape like that of the nozzle (6) and the portion of the body (2) wherein the nozzle (6) is inserted between itself and the floor is inclined. Thus the user, while standing up, can easily slide in the nozzle (6) under the body (2) into the space between the body (2) and the floor for mounting the nozzle (6) to the body (2) by means of the locking mechanism (7).

[0029] In an embodiment of the present invention, the locking mechanism (7) comprises a housing situated on the base of the body (2) and a protrusion disposed on the nozzle (6) that goes into the housing to be locked when inserted under the body (2). Consequently, the nozzle (6) is mounted to the body (2) and the vacuum cleaner (1) is moved by the user by pulling from the handle (5).

[0030] When the user desires to carry the vacuum cleaner (1), the nozzle (6) is inserted between the body (2) and the floor on which the body (2) stands such that the protrusion thereon is fitted into the housing on the body (2). The protrusion that is inserted in the housing moves inside the housing and is locked to the housing. Thus the nozzle (6) is mounted by locking to the body (2). In this position, the user can drag along the body (2) that is mounted to the nozzle (6) by pulling from the handle (5). Attaching the nozzle (6) to the end of the pipe, movable within certain angles allows for easily maneuvering the vacuum cleaner (1) while carrying. Consequently, the body (2) is integrated with the nozzle (6) without lifting up from the floor and can be carried by pulling from the handle (5) (Figure 2).

[0031] In another embodiment of the present invention, the locking mechanism (7) comprises a slide (9) preferably disposed on the base of the body (2) and a rail (8) situated on the nozzle (6) that enters into the slide (9) and locks when inserted under the body (2). Thus the nozzle (6) is attached to the body (2) and the vacuum cleaner (1) can be carried by the user by pulling from the handle (5). The slide (9) and rail (8) pair allows the nozzle (6) to be attached to the body (2) more easily (Figure 3 and Figure 4). In this embodiment, the locking mechanism (7) comprises a diverter that functions as a guide for the slide (9) and the rail (8) to be easily fitted to each other, maintaining the nozzle (6) to be more easily attached, detached to and from the body (2).

[0032] In another embodiment of the present invention, the vacuum cleaner (1) comprises a platform (11) whereon the locking mechanism (7) is disposed that can rotate around its axis. In this embodiment, for example the slide (9) situated on the base of the body (2) is disposed on the platform (11). Thus, the body (2) can be maneuvered to the right and left while the vacuum cleaner (1) is carried (Figure 5).

[0033] By means of the present invention, the user does not have to stoop to carry the vacuum cleaner (1). The nozzle (6) can be attached on the body (2) without lifting the body (2) from the floor and the user can pull and drag along the vacuum cleaner (1) by means of the handle (5).
