In the left-handed arrangement, the arm support portion 16 is arranged so as to protrude to the left side of the grip portion 15.

  FIG. 7 is an enlarged view of a main part of the electric vacuum cleaner 1 shown in FIG. As shown in FIG. 7, the arm support portion 16 is provided on the connecting portion 19 via a shaft 20, for example. The arm support portion 16 rotates around the shaft 20 and is disposed at a right-handed position and a left-handed position as necessary. The operation body 4 has a function of fixing the arm support portion 16 to a right-handed position and a left-handed position. The arm support portion 16 is fixed by switching to each position as necessary.

  FIG. 8 is a perspective view showing another state of the electric vacuum cleaner according to Embodiment 1 of the present invention. FIG. 8 shows a state in which the arm support portion 16 is disposed at a position when the user grips and operates the upper grip portion 18 (hereinafter also referred to as “center position”). FIG. 9 is a side view showing a main part of the vacuum cleaner 1 shown in FIG. FIG. 10 is an enlarged view of a main part of the electric vacuum cleaner 1 shown in FIG.

  When the arm support portion 16 is disposed at the center position, the upper end portion projects upward from the upper gripping portion 18. When the arm support part 16 is provided in the connection part 19 via the axis | shaft 20, the arm support part 16 rotates centering on the axis | shaft 20, and is arrange | positioned also in the center position as needed. The function of fixing the arm support 16 is also provided at the center position. The arm support 16 is fixed by switching to the right-handed position, the left-handed position, or the center position as necessary.

  FIG. 11 is a diagram illustrating a state when the electric vacuum cleaner 1 is used. FIG. 11 shows a state in which the user holds the upper grip 18 and puts his arm on the arm support 16 disposed at the center position. The arm support unit 16 supports, from below, a portion between the wrist and the elbow of the user's arm holding the grip unit 15.

  In the vacuum cleaner 1 having the above configuration, the arm support portion 16 protrudes to the side of the grip portion 15. For this reason, the arm of the user can be appropriately supported by the arm support portion 16 without causing the arm support portion 16 to largely protrude from the grip portion 15. By providing the arm support portion 16, the operability is not impaired. Moreover, the arm support part 16 is arrange | positioned so that the part between a user's wrist and elbow may be supported from the downward direction. For this reason, the user can easily perform an operation of lifting the suction port body 6 or moving it to the left or right.

  For example, when the suction port body 6 is lifted from the floor surface, the user holds the lower gripping portion 17 and hits the arm against the arm support portion 16. At this time, the user can easily lift the suction port body 6 by using the lever principle without strongly squeezing the lower gripping portion 17. That is, the portion gripping the lower grip 17 may be a fulcrum, the portion where the arm is in contact with the arm support 16 may be the power point, and the suction port 6 may be the point of action.

  Further, when the suction port body 6 is moved left and right from that state, the user applies the wrist portion of the arm holding the lower gripping portion 17 to the upper gripping portion 18. At this time, by using the lever principle, the user can easily move the suction port body 6 to the left and right without strongly grasping the lower gripping portion 17. That is, a portion gripping the lower gripping portion 17 may be a fulcrum, a portion where the upper gripping portion 18 is in contact with an arm (wrist) may be a power point, and the suction port body 6 may be a working point.

  The user can also perform cleaning while holding the upper grip 18 and moving the suction port body 6 back and forth. At this time, if the arm support portion 16 is fixed at the center position, the arm can be applied to the arm support portion 16 to reduce labor.

The arm support portion 16 may be configured to be disposed only at a right-handed position or a left-handed position. However, with the arm support portion 16 having the above-described configuration, the arm support portion 16 can be disposed at an appropriate position in accordance with the arm that holds the grip portion 15.
The arm support portion 16 may be provided so as to be detachable from the grip portion 15. With this configuration, the arm support 16 can be detached from the grip 15 when the arm support 16 is not required.

  In consideration of operability, it is preferable that the arm support portion 16 is disposed behind the position where the hose 3 is connected to the operation body 4. By providing the arm support portion 16 in the connecting portion 19, the arm support portion 16 can be easily arranged at the above position. Moreover, by providing the connection part 19, the intensity | strength required in order to support an arm can be ensured easily.

  Next, another configuration that can be adopted by the vacuum cleaner 1 will be described with reference to FIGS.

FIG. 12 is a perspective view showing another configuration example of the vacuum cleaner 1.
As shown in FIG. 12, a portion of the lower gripping portion 17 that is touched by the user when gripped by the user may be covered with a material having lower hardness than the inside of the lower gripping portion 17 or the upper gripping portion 18. . For example, the lower grip 17 is covered with a soft material. Further, a portion (hereinafter also referred to as “branched portion”) that branches from the tubular body 14 to the lower gripping portion 17 and the upper gripping portion 18 is covered with a soft material. Thereby, the function of anti-slip | skid can be provided to the operation body 4. FIG.
Instead of covering with a soft material, a large number of protrusions or a large number of depressions may be formed on the outer surface of the operation body 4.

As shown in FIG. 11, an inclined surface 21 facing the direction of the suction port body 6 may be formed on the outer surface of the lower gripping portion 17. For example, the inclined surface 21 is formed on an outer surface other than the upward outer surface of the lower grip 17. If the lower gripping portion 17 is formed with a portion that gradually becomes thicker toward the exhaust side, the inclined surface 21 is inevitably formed. The user brings his / her finger into contact with the inclined surface 21 when gripping the lower grip 17. Thereby, when operating the suction inlet body 6, it becomes easy to enter force and operativity improves.
In addition, if the inclined surface 21 is formed on the downward outer surface of the lower gripping portion 17, a certain effect can be expected.

FIG. 13 is a side view showing another configuration example of the vacuum cleaner 1.
As shown in FIG. 13, a convex portion 22 or a concave portion 23 may be formed on the inclined surface 21. FIG. 13 shows an example in which both the convex portion 22 and the concave portion 23 are formed on the inclined surface 21. The convex portion 22 projects downward from the downward inclined surface 21. The recess 23 is an upward recess formed in the downward inclined surface 21. The user can place a finger on the convex portion 22 or the concave portion 23 when gripping the lower gripping portion 17. Thereby, when operating the suction inlet body 6, it becomes easier to enter force and operability improves.

14 to 16 are perspective views showing other configuration examples of the electric vacuum cleaner 1.
As shown in FIGS. 14 to 16, a recess 24 extending from the right outer surface to the left outer surface of the operation body 4 may be formed in the branch portion of the operation body 4. The depression 24 is formed at a portion where the range from the base of the thumb of the hand to the base of the index finger hits when the user grasps the lower gripping portion 17. The recess 24 is formed from the upper surface of the lower gripping portion 17 to the lower surface of the upper gripping portion 18.

  If the depression 24 is formed, the hand will not hurt even if the user brings the hand close to the branching portion when the user grips the lower gripping portion 17. By grasping the lower gripping portion 17 at a position close to the branching portion, the position of the user's hand can be constrained and the operability can be improved. The hand does not slip when the lower grip 17 is gripped.

As shown in FIG.15 and FIG.16, you may curve the surface which hits a user's arm among the outer surfaces of the arm support part 16 in a concave shape. In the present embodiment, the arm support portion 16 is configured to be able to be switched and fixed to a right-handed position, a left-handed position, and a center position. For this reason, among the outer surfaces of the arm support portion 16, the surfaces facing upward at the respective positions are curved in a concave shape.
Further, in order to reduce the load applied to the user's arm in the same manner as described above, the surface of the arm support portion 16 that contacts the user's arm may be formed of a soft member such as rubber.
