It can be retained. Further, traveling wheels 14 are rotatably attached to both sides of the vacuum cleaner main body 1 and a traveling caster 15 is rotatably attached to the front of the lower surface of the cleaner main body 1.

  A handle 11 is provided at an upper front portion of the cleaner body 1, and the handle 11 is rotatable to the cleaner body 1 and a grip 12 used when the user carries the cleaner body 1. It is comprised by the arm part 13 pivotally supported, and is formed in the substantially U shape.

  FIG. 2 is a side view of the cleaner body showing the movable range of the handle 11 according to Embodiment 1 of the present invention. As shown in FIG. 2, the handle 11 is formed so as to be rotatable between a normal position 16 rotated forward and an upper rotary position 17 rotated upward. It is designed to rotate.

In the first embodiment, the dead weight is used as a means for setting the handle 11 to the normal position 16 rotated forward. By adopting a configuration in which the handle 11 is rotated to the normal position 16 by its own weight, the rotation mechanism of the handle 11 can be simplified and can be configured at low cost.

  3A and 3B are diagrams showing the rotational position of the handle 11 and the shape of the handle 11 at the position where the handle 11 contacts an obstacle in the first embodiment of the present invention. FIG. 3A shows the normal position 16 and FIG. ) Indicates the upward rotation position 17.

  At the normal position 16 of the handle 11, as shown in (a) of the side view of the cleaner body 1 in FIG. 3, the grip portion 12 of the handle 11 or the arm portions 13 on both sides of the grip portion 12 come into contact with an obstacle. As shown in FIG. 3A, the grip portion 12 is formed in a rounded rectangle so as to be easily gripped by the user.

  As shown in FIG. 3B in the side view of the cleaner body 1 in FIG. 3, the arm portion 13 of the handle 11 contacts the obstacle at the upper rotation position 17 where the handle 11 has rotated in contact with the obstacle.

As shown in FIG. 3B, the arm portion 13 is formed in a shape that gradually widens from the front to the rear, and is formed in a shape that can easily avoid an obstacle by the movement of the cleaner body 1 accompanying the cleaning operation. doing.

  About the vacuum cleaner 100 comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  When cleaning the surface to be cleaned with the electric vacuum cleaner 100, the user sucks dust and the like from the suction tool 2 by gripping and operating the handle portion 5. The vacuum cleaner main body 1 moves while being pulled by the hose 4 in accordance with the operation of the handle portion 5 in a state where the wheels 14 and the casters 15 are grounded. When the cleaner body 1 moves due to the cleaning operation, the cleaner body 1 may collide with the furniture and damage the furniture.

  In the present embodiment, as shown by the solid line in FIG. 2, the handle 11 is positioned in the traveling direction of the cleaner main body 1, and when the handle 11 collides with an obstacle, the handle 11 is a shaft (not shown). ) Around the center). Specifically, the handle 11 is pivotally supported by the vacuum cleaner main body 1, and when the impact force is not applied to the grip portion 12, the center of the grip portion 12 is at the normal position 16, and the obstacle 11 In the state of collision, the handle 11 is rotated, and the gripping portion 12 is rotated upward to buffer the impact.

  In the first embodiment, the handle 11 restricts the rotation on the front side of the position 18 perpendicular to the rotation axis of the handle 11. By restricting the rotation in this range, the handle 11 returns to the normal position 16 by its own weight when it is separated from the obstacle, so that the usability is improved.

  Further, by setting the rotation restricting position of the handle 11 to a position 17 where the handle 11 is located in front of the front surface of the cleaner body 1, the handle 11 receives all the impact force at the time of collision with an obstacle. It is preferable to configure. The handle 11 is rotated by a collision with an obstacle to buffer the impact force. Therefore, the handle 11 is more easily buffered than the cleaner body 1 and can prevent damage to furniture and the like. It can be improved.

As described above, in the present embodiment, the center of the grip portion 12 of the handle 11 is at the normal position 16 protruding forward of the cleaner body 1 during normal use, and when the handle 11 collides with an obstacle, The handle 11 is rotated rearward, and the center of the grip portion 12 is configured to rotate in a range from the normal position 16 to the upper rotation position 17. When the user cleans the surface to be cleaned, when the cleaner body 1 collides with an obstacle, the handle 11 rotates against the obstacle, so that a part of the impact force is used for the rotational force of the handle 11. In addition to being buffered by turning, it is possible to sufficiently prevent damage to furniture and the like, and the usability of the vacuum cleaner 100 can be improved.

  Further, as shown in FIG. 2, in the present embodiment, in the normal state, the handle 11 is positioned at the forefront of the handle 11 and is rotated upward by colliding with an obstacle and rotating upward. 17, the front surface of the arm portion 13 is configured to be positioned at the forefront of the handle 11, and the arm portion 13 guides the cleaner body 1 in a direction to escape from the obstacle as shown in FIG. It is formed on an inclined surface or a curved surface. During cleaning, when the cleaner body 1 collides with an obstacle, the handle 11 can be easily detached from the obstacle by the inclined surface or curved surface of the arm portion 13 after the impact is reduced by turning the handle 11. Usability of the vacuum cleaner 100 is improved.

  In the normal state, the handle 11 is rotated forward, but can be easily rotated upward, so that it does not interfere with the attaching / detaching operation of the hose 4 to the cleaner body 1.

  When the electric vacuum cleaner 100 is stored, the back surface of the vacuum cleaner body 1 is grounded to be in an upright state, and the hose 4 connected to the suction tool 2 and the extension tube 3 is connected to the cleaner body 1, and the extension pipe 3 The stopper is locked to the locking portion 23 to be in the stored state.

  In conventional vacuum cleaners, the handle is positioned above the vacuum cleaner body so that it can be easily gripped with the wheels of the vacuum cleaner grounded. Is formed on the bottom of the vacuum cleaner body, and when lifting the vacuum cleaner in the stored state by gripping the handle part, the weight balance is poor, it is difficult to carry with a large inclination, and it is carried because the inclination is large There was a risk that the extension pipe would be unlocked and dropped due to shaking or the like, and the floor surface could be damaged.

  In the vacuum cleaner of the present invention, since the locking portion 23 of the extension pipe 3 is formed in the vicinity of the lower position of the grip portion 12 of the handle 11 in the storage state of the vacuum cleaner, the vacuum cleaner 100 is set in the storage state. The electric vacuum cleaner 100 can be moved while maintaining a stable state without being greatly inclined when lifted. In addition, since the handle 11 can be rotated, vibration generated during movement can be absorbed by the rotation of the handle 11, and the vacuum cleaner 100 may be unexpectedly tilted or the like. This can be prevented and the transportability in the stored state can be improved.

  The locking portion 23 of the electric vacuum cleaner 100 of the present invention is preferably formed in the cover body 10 on the cord reel chamber side of the cleaner body 1. Since an electric blower that is a heavy object is built in the opposite side of the cord reel chamber, the extension pipe 3 to which the suction tool 2 is connected is locked to the cord reel chamber side in which the cord reel that is a lightweight object is stored. Thereby, the weight balance of the left-right direction of the vacuum cleaner 100 at the time of carrying the vacuum cleaner 100 can be improved.

  Moreover, the latching | locking part 23 can also be formed in the cover body 10 of both sides. By forming the cover bodies 10 on both sides, the extension pipe 3 can be locked to either the right or left locking portion 23 according to the storage location or usage state, and the usability can be improved.

  Further, the locking portion 23 may be formed on the bottom surface side of the cleaner body 1 as in the conventional case. Even when the locking portion 23 is formed on the bottom surface side of the cleaner body 1, the interval between the locking portion 23 and the grip portion 12 of the handle 11 can be narrowed, improving the weight balance, Transportability can be improved.

(Embodiment 2)
Embodiment 2 of the vacuum cleaner 100 of the present invention will be described with reference to FIGS. 4 and 5. Note that the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  4A and 4B are cross-sectional views of the handle 11 for explaining the configuration of the handle 11 according to the second embodiment of the present invention. FIG. 4A shows an upward rotation state, and FIG. 4B shows a normal state.

  A kick spring A <b> 20 is provided on the shaft 19 of the handle 11. One end of the kick spring A <b> 20 is fixed to the cleaner body 1, and the other end is in contact with the handle 11.

  The handle 11 is located at the normal position shown in FIG. 4B by the elastic force of the kick spring A20 provided on the shaft 19, and an external force is applied in the rearward direction when the cleaner body 1 collides with an obstacle. When the external force disappears, it rotates to the normal position by the urging force of the kick spring A20. In the handle 11, a restricting mechanism (not shown) is formed in the vicinity of the shaft 19 to restrict the forward and upward rotation by contacting the cleaner body 1.

  Further, as shown in FIG. 5, the handle 11 is configured such that the center of gravity 21 of the vacuum cleaner 100 is positioned substantially below the grip portion 12 when the vacuum cleaner 100 is stored.

  Therefore, as shown in FIG. 5, when carrying the vacuum cleaner 100 in the housed state, the grip portion 12 is positioned on the vertical line of the center of gravity 21 of the vacuum cleaner 100, so that the vacuum cleaner body 1 is lifted. The burden on the user's arm due to the change of the center of gravity 21 of the vacuum cleaner 100 can be reduced, the transportability of the vacuum cleaner 100 can be improved, and the usability can be improved.

  Since the handle 11 is maintained at the forward rotation position by the kick spring A20, the handle 11 is maintained at a high position in the housed state of the vacuum cleaner 100, and the user can easily grip the grip portion 12, Usability can be improved.

(Embodiment 3)
Embodiment 3 of the vacuum cleaner 100 of the present invention will be described with reference to FIG. In addition, the same code | symbol is attached | subjected about the same component as Embodiment 1 and Embodiment 2 mentioned above, and the description is abbreviate | omitted.

  FIG. 6 is a cross-sectional view of the handle 11 for explaining the configuration of the handle 11 according to Embodiment 3 of the present invention.

  As shown in FIG. 6, in the present embodiment, the cleaner body 1 is provided with a kick spring B22 on the shaft 19 that is the rotation center of the handle 11, and one end of the kick spring B22 is fixed to the cleaner body 1, The end is in contact with the handle 11, urges the handle 11 forward by a kick spring B22, and restricts rotation of the handle 11 to the rear.

  About the vacuum cleaner 100 comprised in this way, the operation | movement and an effect | action are demonstrated below.

  The handle 11 is biased by the elastic force of the kick spring B22 provided on the shaft 19 and is rotated to the normal position. When the handle 11 collides with an obstacle and an external force is applied in the rear direction, the handle 11 pushes the kick spring B22. When it is retracted, it rotates backward about the shaft 19 and when there is no external force, it returns to the normal position 16 by the elastic force of the kick spring B22. Therefore, the impact force is transmitted to the kick spring B22 having a large deformation amount, so that the impact force can be further relaxed, and damage to obstacles such as furniture can be prevented even with a greater impact. Usability of the vacuum cleaner 100 can be improved.

  In the third embodiment, the configuration in which the handle 11 is urged by the kick spring B22 even when the handle 11 is disposed at the normal position 16 is urged by the kick spring B22 from the middle of the rotation. Even in the case, the effect of improving the buffering action of the present invention is obtained, and the usability of the vacuum cleaner 100 is improved. When urged from the normal position, the position of the handle 11 is stable and does not move due to vibration during cleaning. Also, when the cleaner 11 is placed in a vertical state and the handle 11 is held, Since the vacuum cleaner main body 1 is lifted more easily because the handle 11 is at a higher position, it is better to be biased by the kick spring B22 from the normal position 16.

  As mentioned above, although Embodiment 1, Embodiment 2, and Embodiment 3 of this invention were demonstrated, the vacuum cleaner 100 of this invention is limited to Embodiment 1, Embodiment 2, and Embodiment 3 mentioned above. Is not to be done.

  In the first embodiment, the second embodiment, and the third embodiment described above, the description has been given of the configuration in which the arm portion 13 of the handle 11 is formed with the curved surface that guides the cleaner body 1 in the direction of escaping from the obstacle. An inclined surface (not shown) that leads in a direction to escape from the obstacle may be formed. Even in this configuration, since the vacuum cleaner body 1 can be guided, the user can move the vacuum cleaner body 1 as it is even when the vacuum cleaner body 1 collides with an obstacle. Can be improved.

  Moreover, in Embodiment 3 mentioned above, although the upward rotation of the handle | steering_wheel 11 was controlled by kick spring B22, the soft material which has a restoring force at the contact part of the handle | steering-wheel 11 and the cleaner body 1 is arrange | positioned. It only has to be done.

  Since the outer shell of the handle 11 is made of a soft material, the buffer performance can be improved, and the usability of the vacuum cleaner 100 can be improved.
