The hand handle body 410 and the grip portion 401 are integrally formed of a resin material or the like.

  The hand handle main body 410 has a cylindrical connecting tube storage portion 402 that also serves as a dust ventilation path formed therein, and the first connecting tube 301 is slid inside the connecting tube storage portion 402 so that there is no air leakage. Mounted movably. A plurality of length adjusting grooves 304 are formed at equal intervals along the longitudinal direction of the first connecting pipe 301, and the adjusting grooves 304 are fixed to the lock portion 650 provided at the end of the hand handle body 410. As a result, the connection tube storage unit 402 is held at a predetermined length.

  The lock portion 650 includes a lock member 651 that moves in a direction (arrows X3 and X4) orthogonal to the longitudinal direction of the connecting pipe storage portion 402, and the lock member 651 is always fixed in one direction (arrow X3), that is, fixed. And a spring (not shown) acting in the direction of the state. The lock member 651 is a frame having an open center portion such as “R” shape or “U shape” when viewed from the longitudinal direction of the connecting tube storage portion 402, and the connecting tube 300 is formed in the center portion. Be placed.

  In this embodiment, the adjustment groove 304 is provided on the back side of the connecting pipe 300 so that the adjustment groove 304 cannot be seen when viewed from the front direction shown in FIG. On the other hand, the switch 600 for operating expansion and contraction of the connecting pipe 300 is provided on the front side facing the back side where the adjustment groove 304 is provided. Therefore, in order to connect the adjustment groove 304 and the switch 600 facing each other across the connection pipe 300, the lock member 651 having an open central portion is employed.

  One end side 651 a of the lock member 651 has a structure to be fitted with the adjustment groove 304, and the other end side 651 b is viewed from the longitudinal direction of the connecting pipe housing portion 402 via a push member 671 constituting the transmission mechanism portion 670. It has a structure that can be pushed. The lock member 651 moves in the X4 direction by the operation of being pushed from the push member 671.

  Here, the distal end portion of the push member 671 has a wedge shape with an inclined surface, and when the push member 671 moves in the X7 direction, the one end side 653b of the lock member 651 is pushed by the inclined surface and X4. Move in the direction.

  In addition, the switch 600 for operating the lock portion 650 is disposed inside the arch-shaped grip portion 401. In this embodiment, it is assumed that the switch 600 is operated with an index finger of a hand gripping the grip portion 401. For this reason, the operation of pulling the switch 600 with the index finger of the hand holding the grip portion 401, that is, moving the switch 600 in the direction of the arrow X6 so that the fixed state of the lock portion 650 is released. The operation of the switch 600 is transmitted to the lock unit 650 through the transmission mechanism unit 670.

  The transmission mechanism portion 670 includes the push member 671 that is in contact with the lock member 651 of the lock portion 650, a first connecting rod 672 that has one end attached to the push member 671, and the first connecting rod 672. A transmission plate 673 attached to the other end of the transmission plate, a second coupling rod 674 with one end attached to the transmission plate 673, and a spring (not shown) provided on the transmission plate 673, and the second coupling rod. The other end of 674 is attached to the switch 600.

  The transmission plate 673 is a vertically long track-shaped plate member, the central portion of which is rotatably attached to the mounting rib 411 of the hand handle body 410, and one end in the longitudinal direction thereof is connected to the first connecting rod 672 and the other One end is attached to one end of the second connecting rod 674.

  One of the functions of the transmission plate 673 is to reverse the pulling force (arrow X6) of the switch 600 into a pressing force (arrow X7). One of the other functions of the transmission plate 673 is to smoothly transmit the pulling force (arrow X6) of the switch 600 to the lock unit 650. In other words, in this embodiment, the switch 600 is provided in the grip portion 401 formed by rising at a predetermined angle α1 (around 30 degrees) with respect to the longitudinal direction of the hand handle body 410. Accordingly, the pulling force (arrow X6) of the switch 600 is a predetermined angle α1 with respect to the longitudinal direction of the hand handle body 410, and the forces of the arrows X3 and X4 that operate the lock member 651, that is, the connecting tube storage portion 402 ( This is different from the direction orthogonal to the longitudinal direction of the hand handle body 410), and it is difficult to transmit an efficient or smooth operation.

  Therefore, in this embodiment, a transmission plate 673 is provided in the intermediate portion of the transmission mechanism section 670 so that the direction of the acting force is changed from the X6 direction to the X7 direction. Specifically, the rotation shaft 653 of the transmission mechanism 670 is set to a horizontal position extending left and right in a state where the longitudinal direction of the hand handle body 410 is vertical. Then, the first connecting rod 672 is arranged in a posture parallel to the longitudinal direction of the hand handle main body 410, and the transmission plate 673 is attached to the mounting rib 411 so that one end of the transmission plate 673 is connected to this one end. . By providing such a structure, the transmission mechanism 670 can be housed in an arch-shaped grip 401 formed by gradually rising from one end of the hand handle body 410.

  Next, the expansion / contraction mechanism of the connecting pipe 300 will be further described with reference to FIGS. 7A shows a state in which the first connecting pipe 301 is fixed via the lock portion 650.

When the operation of pulling the switch 600 in the X6 direction is performed from the state of FIG. (A), this operation rotates the transmission plate 673 in the X8 direction via the second connecting rod 674 extending obliquely. The rotation operation of the transmission plate 673 in the X8 direction is converted into a force (arrow X7) that pushes the first connecting rod 672 attached to the other end of the transmission plate 673. This pushing force (arrow X7) slides the pushing member 671 in the X7 direction. The distal end portion of the push member 671 has an inclined surface. When the lock member 651 is pushed in the X7 direction via the push member 671, the other one end side 651b of the lock member 651 moves on the inclined surface. The lock member 651 moves in the X4 direction. When the lock member 651 moves in the X4 direction, the other end side 653a of the lock member 651 and the adjustment groove 304 are disengaged, and the first connection tube 301 can be slid in the longitudinal direction of the connection tube storage portion 402. Possible (b) state as shown.

  In this embodiment, the fitting between the first connecting pipe 301 and the connecting pipe storage portion 402 is adjusted so that there is no air leakage. For this reason, as shown in FIG. 5B, when the longitudinal direction of the hand handle 400 is set to the up and down direction, the connection pipe 300 including the first connection pipe 301 has the vacuum cleaner main body 100 remaining on the floor by its own weight. And can be easily extended upward. Therefore, the user can easily extend the connecting pipe 300 by operating the switch 600 and pulling up the hand handle, so that one-handed operation is possible.

  In the embodiment of FIG. 7, the example in which the switch 600 is disposed inside the grip portion 401 has been described, but the present invention is not limited to this. For example, as shown in FIG. 8, the same type of switch 601 may be provided outside the grip portion 401. In this case, the switch 601 is operated with the thumb holding the grip portion 401.

  When operating with the thumb, the pressing operation is natural. Therefore, in this embodiment, for example, the center of the switch 601 is rotatably supported inside the grip 401, and one end of the second connecting rod 674 is attached to one end inside the switch 601 and the other end outside. With a thumb in the X9 direction.

  That is, the state of FIG. (A) shows a state where the first connecting pipe 301 is fixed via the lock portion 650. Also in this embodiment, the fixed state shown in FIG. 5A is maintained by a spring (not shown) provided on the transmission plate 673. When the operation of pushing the outside of the switch 601 in the X6 direction is performed from the state of FIG. 9A, this operation rotates the switch 601 in the X10 direction. Then, this rotating force becomes a force pulling the second connecting rod 674 attached to one end inside the switch 601, and rotates the transmission plate 673 in the X8 direction. Thereafter, the movement is the same as that of the embodiment of FIG.

  Returning to FIG. 6, in this embodiment, a power button 171 a may be provided outside the grip portion 401. As a result, the switch 600 can be operated with the index finger of the hand that supports the grip portion 401 to perform the expansion and contraction of the connecting pipe 300, and the vertical vacuum cleaner 1 is turned on and off with the thumb of the supporting hand. It can be performed.

  In this embodiment, a projection (not shown) that prevents the first connection pipe 301 from falling off is provided at the end of the first connection pipe 301 stored in the connection pipe storage section 402.

In this embodiment, the lengths of the first connecting pipe 301 and the second connecting pipe 302 are set so that most of the connecting pipe 300 can be accommodated in the hand handle 400 in the state shown in FIG.

  Further, one end of the dust hose 70 is attached to the upper end of the hand handle 400 by being bent with respect to the longitudinal direction of the connecting pipe 300 (hand handle). For this reason, it is reduced that the dust hose 70 becomes obstructive during cleaning. Furthermore, if this attachment portion can be rotated with respect to the shaft center of the hose, twisting of the dust hose 70 can be reduced.

  Next, a usage pattern according to this embodiment will be described with reference to FIGS. 1, 10, and 11. The state of FIG. 1 shows the storage state and the clearance cleaning state at the hand handle assembly 50. First, as shown in FIG. 1, in this embodiment, the vacuum cleaner main body 100 can be installed in a posture in which the longitudinal direction is vertical by raising the universal connection portion 210 of the mouthpiece 200. If the hand handle assembly 50 is attached to the cleaner body 100 in this state, it can be stored compactly in a narrow installation space. Further, when the installation space cannot be taken, the entire height can be kept low by operating the switch 600 and contracting the connecting pipe 300, so that it can be stored in various storage spaces.

  Further, in this embodiment, in a state in which the universal connection portion 210 of the mouthpiece 200 is upright, the communication between the universal connection portion 210 and the mouthpiece 200 is blocked, and dust-containing air cannot be sucked from the mouthpiece 200. It has a structure. For this reason, when the power button 171 is turned on with the universal connection part 210 of the mouthpiece 200 in the upright state, the suction handle 200 can only be sucked from the hand handle assembly 50. Therefore, when the hand handle assembly 50 is removed from the cleaner body 100 and the gap cleaning is performed, the suction force is concentrated in the gap, so that efficient cleaning is possible.

In addition, the hand holding the vacuum cleaner 100 can be turned on and off, and the hand holding the hand handle 400 can be used to extend and retract the connecting pipe 300, so that the connecting pipe can be turned on and off. Because of the expansion / contraction operation of 300, continuous cleaning is possible without interrupting the cleaning.

  Further, in this embodiment, since the power button 171 and the hose connecting portion 180 are arranged on both sides of the detachable button 501, as described with reference to FIG. 11, the detachable button 501 and the power button 171 It is reduced that the dust hose 70 connected to the hose coupling part 180 becomes an obstacle during operation.

  Furthermore, since the dust hose 70 connected to the hose coupling portion 180 is vertically attached to the offset position on the upper surface of the cleaner body 100, the loose dust hose 70 is less likely to get in the way in the housed state. Furthermore, when the cleaner main body 100 is held with one hand via the main body handle portion 140, the dust hose 70 is in a posture along the side surface of the user, so that portability can be improved.

  Further, as shown in FIG. 10, when the vacuum cleaner main body 100 is tilted backward from the housed state of FIG. 1, the suction body 200 is released from the fixed state, and air containing dust from the suction body 200 can be taken in. At this time, since the hand handle assembly 50 is attached to the cleaner body 100, the tip of the connecting pipe 300 is attached to the connecting pipe attaching portion 151 and sealed, so that air containing dust from the mouthpiece 200 is included. Can be imported. Of course, if the hand handle assembly 50 is removed from the cleaner body 100 in this state, air containing dust can be taken in from both the suction body 200 and the hand handle assembly 50.

  Further, in the cleaning posture with the mouthpiece 200 in FIG. 9, for example, the grip 401 of the hand handle 400 is held with one hand, and the vertical cleaner 1 is operated with one hand while holding the power cord 132 with the other hand. Floor cleaning is possible. Here, the mouthpiece 200 is capable of rotating in the X1 direction and the X2 direction via the universal connecting portion 210, and the mouthpiece 200 has wheels 221 and thus has a grip 401. It is easy to change the direction of the vertical cleaner 100 by linear movement of the vertical cleaner 100 by one-handed back-and-forth movement or by tilting the left-right direction with one hand holding the grip portion 401.

  At this time, since the connecting pipe mounting portion 151 is disposed on the upper surface front portion and the grip portion 401 of the hand handle 400 is formed by raising a predetermined angle, the axis Q connecting the grip portion 401 and the wheel 221 is formed. Thus, the position of the center of gravity of the cleaner body 100 can be set to a close position. That is, when the gripping portion 401 of the hand handle 400 is held with one hand and the motion of the vertical cleaner 1 is operated, the closer the center of gravity P of the cleaner body 100 is to the position of the axis Q, the closer to the screw in the X2 direction. Re-operation is easy. In this embodiment, by providing the above configuration, the twisting operation can be easily performed as compared with the conventional product.
