  The handle 39 is connected to the first connecting portion of the first support portion 41 in a direction orthogonal to the main body side extension pipe 4 and the brush side extension pipe 6, that is, in a direction orthogonal to the traveling direction of the cleaner body 1. It is attached to 43 integrally. For this reason, the handle 39 protrudes in a horizontal direction with respect to the floor surface. In addition, a cloth portion 48 that serves as a slip stopper for the operator's hand is provided on the entire outer periphery of the handle 39.

  Engaging portions 51 and 52 are provided in the vicinity of the connection portions with the main body side extension tube 4 and the brush side extension tube 6, which are in the vicinity of both ends of the hose body 5. The engaging portion 51 is provided on the front side of the main body side extension tube 4 below the hose body 5 so as to face the brush side extension tube 6. Similarly, the engaging portion 52 is provided on the rear side of the brush side extension pipe 6 below the hose body 5 so as to face the main body side extension pipe 4.

  Further, both end portions of a rigid material 53 as an angle restricting means are removably attached to the engaging portions 51 and 52, respectively. The rigid member 53 is for setting a bending angle between the main body side extension tube 4 and the brush side extension tube 6 to a predetermined angle, and is formed in an elongated cylindrical shape with a member such as metal.

  Next, the cleaning operation according to the above embodiment will be described.

  First, the base end side of the bent pipe portion 15 is connected to the main body suction port 3 of the cleaner body 1, and the floor brush 8 is connected to the front end side of the brush side distal end extension pipe 6 b of the brush side extension pipe 6.

  Next, the operator expands and contracts the main body side extension tube 4 and the brush side extension tube 6 to set the height position of the handle portion 9 according to the height of the operator.

  In this state, a plug portion of a power cord (not shown) derived from the cleaner body 1 is connected to an outlet provided on a wall or the like, and the setting button 7 is operated to drive the electric blower 2 in a predetermined drive mode.

  The operator holds the handle 39 with both hands and cleans the floor brush 8 by running back and forth on the floor surface.

  The dust sucked together with the air from the front end side of the floor brush 8 passes through the brush side extension pipe 6, the hose body 5, the main body side extension pipe 4, the bent pipe part 15, and the main body suction port 3 into the cleaner body 1. And is collected by a paper pack (not shown) in the cleaner body 1.

  Further, when the operator once removes the hand from the handle 39 during cleaning, both ends of the rigid member 53 are engaged with the engaging portions 51, 52, and the main body side extension pipe 4 and the brush side extension pipe are engaged. The bending angle of 6 is fixed to a predetermined angle, and the main body side extension pipe 4 and the brush side extension pipe 6 are in a self-supporting state.

  Further, when the cleaning is completed, the electric blower 2 is stopped by operating the setting button 7, the plug portion of the power cord is removed from the outlet, the power cord is accommodated in the cleaner main body 1, and the main body side extension tube 4 and the brush side extension pipe 6 are contracted to fix the main body side magnet 16 and the brush side magnet 26 to each other to house the vacuum cleaner.

  As described above, according to the above embodiment, the operator holds the handle 39 with both hands by projecting the handle 39 substantially vertically with respect to the main body side extension tube 4 and the brush side extension tube 6. For example, the floor brush 8 can be easily operated as compared with the conventional case of cleaning by holding the handle with one hand, and the cleaning property can be improved.

  Furthermore, since the handle 39 can be operated with both hands, cleaning can be performed while assisting the worker's walking.

  Further, by setting the bending angle of the main body side extension tube 4 and the brush side extension tube 6 to an arbitrary angle with the rigid material 53, the handle 39 can be set to an arbitrary height position, so that workers of various heights can be set. Usability is improved and usability is improved.

  In addition, by fixing the main body side extension pipe 4 and the brush side extension pipe 6 at a predetermined angle by the rigid material 53, the extension pipes 4 and 6 can be self-supporting with respect to the floor surface. Compared to the conventional case where a hose or extension pipe is placed on the floor surface when the operation is interrupted, the workability is improved without the operator performing exercise including bending and stretching. .

  And since each extension pipe 4 and 6 becomes independent with respect to a floor surface, it also becomes possible to clean only by operating the handle 39 back and forth in this independent state. In this case, since it is not necessary for the operator to work while supporting the extension pipes 4 and 6 and the floor brush 8 against gravity, the operator's arm and the like are less likely to get tired and the cleaning property is better. Become.

  Furthermore, since the main body side extension pipe 4 and the brush side extension pipe 6 are composed of the base end extension pipes 4a and 6a and the tip end extension pipes 4b and 6b, they can be expanded and contracted. 4 and 6 can be extended and cleaned. When storing, the extension tubes 4 and 6 can be retracted to be compact so that the storage space can be reduced and the length of the main body side extension tube 4 and the brush side extension tube 6 can be reduced. By changing the balance, it is possible to deal with various forms of cleaning.

  Furthermore, in the conventional case of connecting and using a flexible hose and a pipe-like extension pipe, the hand operating part may be pulled to the cleaner body side by expanding and contracting the hose itself, In the above-described embodiment, since the extension tubes 4 and 6 themselves do not expand and contract or bend, a force for pulling the handle 39 to the cleaner body 1 side or the like is not applied during the operation, and the handle 39 can be easily operated. In addition, since the center of gravity does not bend downward due to bending like a hose, an unnecessary moment does not occur when the handle 39 is operated, and the handle 39 can be easily operated, and each extension tube 4, It is also possible to prevent the 6 from being dragged on the floor surface.

  The main body side magnet 16 and the brush side magnet 26 fix the extension tubes 4 and 6 to each other so that the extension tubes 4 and 6 can be stored more easily, and the extension tubes 4 and 6 are not separated from each other during storage. The storage space can be made smaller.

  In the above-described embodiment, a configuration in which at least one of the engaging portions 51 and 52 is provided in plural and the bending angles of the extension tubes 4 and 6 can be set to plural by the rigid material 53 is also possible.

  Further, as shown in FIG. 7, a configuration using a spring 55 which is an elastic body as an urging means instead of the rigid member 53 is also possible. In this case, similarly to the rigid member 53, the bending angle of each of the extension pipes 4 and 6 can be set to a predetermined angle, and cleaning is performed with both end portions of the spring 55 engaged with the engaging portions 51 and 52. Thus, when the operator runs the floor brush 8, the main body of the cleaner 1 follows the floor brush 8 due to the contraction of the spring 55. Therefore, the labor and labor for moving the cleaner main body 1 can be reduced, and the cleaning performance is improved. Become better.

  Further, as the fixing means 27, various other types such as hooks, hook and loop members of hook-and-loop fasteners, or strings can be used in place of the magnets 16 and 26.
