(Embodiment 1)
FIG. 1 shows a vacuum cleaner according to Embodiment 1 of the present invention.

  As shown in the figure, the vacuum cleaner in the present embodiment connects the cleaner body 1 having the moving wheels 2, the floor suction tool 8, and the floor suction tool 8 and the cleaner body 1. A flexible hose 3 and an extension pipe 5 are provided, and a handle 10 for cleaning work that is provided at a place other than the cleaner body 1 and moves the floor suction tool 8.

  Further, one end of the cleaner body 1 and the flexible hose 3 is connected to the main body side main body connection portion 4A provided in the cleaner main body 1 constituting the main body connection portion 4 and the hose side provided in the flexible hose 3. The main body connection unit 4B is connected. One end of the flexible hose 3 and one end of the extension pipe 5 sandwich the intermediate connector 6, and one end of the intermediate connection part 6 is connected to a hose side extension pipe connection part 7A provided in the flexible hose 3, The other end of the intermediate connection portion 6 is connected to an extension tube side extension tube connection portion 7B provided on the extension tube 5 to constitute the extension tube connection portion 7. One end of the extension pipe 5 and one end of the floor suction tool 8 are connected to the extension pipe side floor suction tool connection part 9A provided in the extension pipe 5 constituting the floor suction tool connection part 9 and the floor suction tool 8 respectively. The floor suction tool side floor suction tool connecting portion 9B provided is connected. A handle 10 for cleaning work for moving the floor suction tool 8 is provided on the extension pipe 5.

And between the said handle | steering-wheel part 10 and the said wheel 2, the damper part 11 which suppresses the movement of the cleaner body 1 during cleaning operation is provided.

  Next, the structure of the damper part 11 is demonstrated based on FIGS.

  Although it is the structure shown in FIG. 2, although it has the structure by which the conducting wire 3A was wound helically in the flexible hose 3, the thing which made the viscous body 11A linear form one of the conducting wires 3A The damper portion 11 is configured by replacing the above. The viscous body 11A is made of a material such as rubber or clay having a high damping characteristic that generates a larger resistance as it expands and contracts at a higher speed. That is, a hose damper portion is configured. If the damper portion 11 is disposed on the entire flexible hose 3, the weight of the damper portion 11 is dispersed, and the usability of the flexible hose 3 is not impaired even if the weight increases.

  In FIG. 3, the connection damper portion is arranged as the damper portion 11 in the intermediate connector 6. That is, the extension pipe side connection tool 6A and the hose side connection tool 6B of the intermediate connection tool 6 are components of the damper part 11, and the damper part 11 is configured by inserting a viscous body 11B made of fluid between the connection tools. .

  In FIG. 4, a wheel damper portion is disposed on the wheel 2 of the cleaner body 1. That is, the damper portion 11 is configured by disposing a ring-shaped viscous body 11 </ b> C around the axle 2 </ b> A of the wheel 2.

  In FIG. 5, only the viscous body 11 </ b> A shown in FIG. 2 is wound around the flexible hose 3, and the conductor 3 </ b> A is not wound around the flexible hose 3, but the outside of the movable hose 3 is folded. Is configured. Moreover, it is good also as a structure which made the conducting wire 3A lie inside rather than the outside of the flexible hose 3. Conversely, the conductive wire 3A may be wound around the flexible hose 3 and the viscous body 11A may not be wound, or the conductive wire 3A and the viscous body 11A may not be wound around the flexible hose 3.

  In FIG. 6, the damper portion 11 is configured by forming part or all of the intermediate connector 6 into the viscous body 11D, and the movement transmitted from the extension tube side connector 6A to the extension tube connector 6B is attenuated. .

  About the vacuum cleaner comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  When the vacuum cleaner is activated, suction force is generated by the electric blower inside the vacuum cleaner main body 1, and dust on the floor surface flows from the floor suction tool 8 to the floor suction tool connection portion 9, the extension pipe 5, the intermediate connection tool 6, It passes through the flexible hose 3 and the main body connection portion 4 and is sucked into the cleaner main body 1.

  During the cleaning work, the floor suction tool 8 is moved back and forth by moving the handle 10 to the hand. Further, by moving the handle part 10 back and forth, the extension pipe 5, the extension pipe side extension pipe connection part 7B, the intermediate connection tool 6, the hose side extension pipe connection part 7A, the flexible hose 3, and the main body connection part 4 The cleaner body 1 is moved.

  At this time, the flexible hose 3 is moved by the movement of the handle portion 10. By this movement, the flexible hose 3 expands and contracts back and forth as a whole, and the viscous body 11A also expands and contracts accordingly. For this reason, the motion is attenuated by the viscous body 11A. Since the viscous body 11A is made of a material having a large resistance and damping as it rapidly expands and contracts, the damping becomes larger as the handle portion 10 moves faster and the flexible hose 3 moves faster. In addition to the flexible hose 3 expanding and contracting as a whole, the viscous body 11A expands or contracts entirely or partially due to twisting or bending, and the movement is attenuated at the expanded or contracted portion (FIGS. 2 and 5).

  Further, in the intermediate connector 6, when the handle portion 10 moves back and forth, the extension tube side connector 6A close to the handle portion 10 is first pulled and moved by the handle portion 10, so that the extension tube side connector 6A and the hose side connection are connected. The damper part 11 between the tools 6B moves and the grip part 10 moves faster back and forth, so that the viscous body 11B or the viscous body 11D attenuates (FIGS. 3 and 6).

  Moreover, in the wheel 2, since the axle 2A rotates when the cleaner body 1 moves, the movement of the cleaner body 1 is attenuated by the damper portion 11 disposed around the axle 2A.

  Accordingly, during the cleaning operation, the movement of the cleaner body 1 is suppressed with respect to the quick movement of the handle portion 10 before and after, and when the operator pulls the handle portion 10, the cleaner body 1 is moved to the intended position. Can be moved.

  In the present embodiment, the damper portion 11 is provided at each location of the flexible hose 3, the intermediate connector 6, and the wheel 2. However, the present invention is not limited to this, and at least one damper portion 11 is provided depending on the case. If it is provided, it may be sufficient. Moreover, the damper part 11 should just be distribute | arranged to the at least 1 connection part of the main body connection part 4, the extension pipe connection part 7, and the floor suction tool connection part 9, and the intermediate | middle connection tool 6 is also the main body similarly. What is necessary is just to provide in at least 1 of the connection part 4, the extension pipe connection part 7, and the suction tool connection part 9 for floors. And the damper part 11 is using these connection parts as a component of a damper part, and is carrying out the integral structure.

  The damper portion 11 (hose damper portion) shown in FIG. 2 has a configuration in which one of the conductive wires 3A is replaced with a viscous body 11A formed in a linear shape with resin or the like, but all the conductive wires 3A are left behind. A linear viscous body 11A may be added and arranged in parallel, or all the conductive wires 3A may be removed and replaced with a linear viscous body 11A. Further, in the figure, the linear viscous body 11A is wound in the same direction as the conducting wire 3A, but is wound in the opposite direction to the conducting wire 3A, and the mesh shape in which the linear viscous body 11A and the conducting wire 3A intersect. It is good also as a structure of. In addition, the linear viscous body 11A has a constant diameter as a whole, but the diameter and shape of the viscous body 11A may be partially changed.

(Embodiment 2)
FIG. 7 shows a vacuum cleaner according to Embodiment 2 of the present invention. The same elements as those of the first embodiment are denoted by the same reference numerals and the description thereof is omitted.

  As shown in the figure, in the present embodiment, the intermediate connector 6 in the first embodiment is omitted, and the handle portion 10 is provided in the flexible hose 3. As shown in FIG. 8, the flexible hose 3 has a layered arrangement of an elastic body 3B around which a conducting wire 3A is wound and a viscous body 11E made of a material such as rubber or clay having high damping characteristics on the outside. The damper portion 11 is formed by the elastic body 3B and the viscous body 11E, and the damper portion 11 is integrated with the flexible hose 3.

  Further, as shown in FIG. 9, the damper portion 11 allows the main body side main body connection portion 4A and the hose side main body connection portion 4B of the main body connection portion 4 to move relative to each other without being completely fixed to each other. It is also configured between the main body side main body connection portion 4A and the hose side main body connection portion 4B by inserting a viscous body 11F with a built-in connection portion into the main body side.

  Moreover, as shown in FIG. 10, the damper part 11 is also comprised by the viscous body 11G attached to the contact surface with the floor surface of the wheel 2 in multiple numbers.

  About the vacuum cleaner comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  The floor suction tool 8 is moved by moving the handle 10 to the hand during the cleaning operation. Moreover, the cleaner main body 1 is moved through the flexible hose 3 and the main body connecting portion 4 by moving the handle portion 10 back and forth.

  At this time, the movement of the handle portion 10 is transmitted to the cleaner body 1 through the flexible hose 3. However, the more the handle portion 10 moves and the flexible hose 3 moves faster, the more the flexible hose 3 moves. , The damper 11 by the viscous body 11E and the elastic body 3B rapidly expands and contracts due to the entire expansion and contraction and / or twisting and / or bending. The viscous body 11E is greatly attenuated as it expands and contracts faster, and the movement transmitted to the cleaner body 1 is attenuated.

  At this time, in the damper portion 11 disposed in the main body connecting portion 4, the main body side main body connecting portion 4A and the hose side main body connecting portion 4B can move relatively back and forth, so the hose close to the handle portion 10 The side main body connecting portion 4B moves first, and the positions of the main body side main body connecting portion 4A and the hose side main body connecting portion 4B are shifted from each other. As a result, the movement is attenuated by the damper portion 11 by the viscous body 11F sandwiched between the main body side main body connection portion 4A and the hose side main body connection portion 4B.

  Furthermore, when the cleaner body 1 starts to move at the wheel 2, the movement of the cleaner body 1 is attenuated by the damper portion 11 by the viscous body 11 </ b> G disposed on the surface of the wheel 2.

  Thus, the cleaner main body 1 is configured to be difficult to move with respect to the quick movement of the handle portion 10 back and forth, and when the operator pulls the handle portion 10, the cleaner main body 1 can be moved to the intended position. .

  In addition, in the vacuum cleaner in this Embodiment, although it has the floor suction tool 8 and the extension pipe 5 as a structure other than between the handle part 10 and the wheel 2, depending on the case, these floor suction tools 8 are provided. Or even if it is the structure which does not have one or all of the extension pipes 5, it can be used.

(Embodiment 3)
FIG. 11 shows a vacuum cleaner according to Embodiment 3 of the present invention. The same elements as those of the first and second embodiments are denoted by the same reference numerals and the description thereof is omitted.

  As shown in the figure, in the present embodiment, the handle portion 10 is provided in the floor suction tool 8. Further, a damper part 11 is arranged on the floor suction tool connecting part 9, and a damper part 11 is also arranged on the wheel 2. Furthermore, a movement detector 8 </ b> A is arranged in the floor suction tool 8.

  And the damper part 11 of the wheel 2 changes the damping characteristic of the magnet 11H arrange | positioned at the side surface of the wheel 2, the electromagnet 11I arrange | positioned at the cleaner body 1, and the damper part 11, as shown in FIG. Therefore, the control unit 11J is configured to change the current flowing through the electromagnet 11I. The control unit 11J operates in response to the signal detected by the movement detector 8A, and can electrically operate the damping characteristic of the damper unit 11. It is said.

  About the vacuum cleaner comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  The floor suction tool 8 is moved by moving the handle 10 to the hand during the cleaning operation. Further, by moving the handle portion 10 back and forth, the cleaner main body 1 is moved through the floor suction tool connecting portion 9, the extension pipe 5, the extension pipe connecting portion 7, the flexible hose 3, and the main body connecting portion 4.

At this time, the movement detector 8A detects the movement of the floor suction tool 8 during the cleaning operation. When the state of work is detected by the movement detector 8A and the floor suction tool 8 repeats the forward and backward movement, it is determined that the worker is not moving and the cleaner body 1 moves back and forth. The control device 11J causes a current to flow through the electromagnet 11I so as to make the configuration difficult, thereby strengthening the magnetic field and increasing the attenuation characteristics. In other cases, it is determined that the worker is moving, and the control device 11J controls the current flowing through the electromagnet 11I so that the cleaner body 1 can move easily, so that the attenuation characteristic is lowered.

  That is, when the movement of the floor suction tool 8 is transmitted to the extension pipe 5, attenuation is performed by the damper portion 11 of the connection portion.

  Accordingly, the cleaner main body 1 is difficult to move with respect to the quick movement of the handle portion 10 forward and backward, and when the operator pulls the handle portion 10, the cleaner main body 1 can be moved to the intended position. .

  At this time, since the metal is attracted by the magnet 11H and the electromagnet 11I, the metal on the floor surface can be recovered.

  In the present embodiment, the movement detector 8A is arranged in the floor suction tool 8, but may be arranged in other places.

  In this embodiment, when the worker does not move during the cleaning work, the damping characteristic at the damper unit 11 is high, and when the worker moves, the damping characteristic at the damper unit 11 is low. In order to operate, the state of work is detected by the movement detector 8A and the control device 11J is operated. However, the movement of the handle portion 10 when the worker does not move and works is checked in advance, and the attenuation performance against the movement The properties of the damper portion 11 may be adjusted so that the height becomes higher.

  In the present embodiment, the state of work is detected from the movement of the floor suction tool 8 by the movement detector 8A and the control device 11J is operated. However, it is not a movement, for example, the angle of the extension pipe 5 with respect to the floor surface And the state of work from the force applied to any one or two or all of the connection parts of the main body connection part, the extension pipe connection part, and the floor suction tool connection part, and the bending method of the flexible hose 3 May be detected.

  In the present embodiment, the magnet 11H is disposed on the wheel 2, but a magnetic body may be disposed instead of the magnet. Moreover, you may arrange | position an electromagnet instead of the magnet 11H. In contrast to the illustrated configuration, the electromagnet 11I may be disposed on the wheel 2 and the magnet 11H may be disposed on the cleaner body 1. Further, the magnet 11H arranged on the wheel 2 may be arranged on the axle 2A.

  The configurations in the first to third embodiments described above can be used in appropriate combinations as needed, and are not limited to the configurations of the embodiments themselves.
