Further, as shown in FIG. 6, the pin pulling mechanism 56 is housed in the pipe case portion 13 together with the pipe member 21.
In FIG. 6, reference numeral 56h is a rib extending in the front-rear direction on the upper surface of the slider portion 56c. The rib 56h is fitted into a groove portion (not shown) formed to extend in the front-rear direction of the upper inner peripheral surface of the pipe case portion 13. Thereby, when the pin pulling mechanism 56 moves in the pipe case portion 13 in the front-rear direction together with the pipe member 21, rattling is more reliably prevented.

  In FIG. 6, reference numeral 21 c is a pin insertion hole formed in the pipe member 21 below the pin 54. Reference numeral 34a denotes a pin insertion hole formed in the lock plate 34 that constitutes the locking portion 52 described below.

<Locking part>
As shown in FIG. 6, the locking portion 52 includes a lock plate 34 disposed below the pipe member 21. The lock plate 34 is fixed to the case 10 constituting the cleaner body 1.

The lock plate 34 is formed of a plate that is elongated in the front-rear direction. A plurality of the pin insertion holes 34a (holes) are formed in the lock plate 34 at predetermined intervals along the front-rear direction. In this embodiment, four pin insertion holes 34a are formed.
When the pin 54 constituting the locked portion 51 is fitted into the pin insertion hole 34 a, the lock / unlock device 50 maintains the locked state of the telescopic pipe 20.

As shown in FIG. 10B, the inner diameter D1 of the pin insertion hole 34a formed on the upper surface of the lock plate 34 is larger than the outer diameter D3 of the pin 54, and the pin insertion hole formed on the lower surface of the lock plate 34. The inner diameter D2 of 34a is the same diameter as the outer diameter D3 of the pin 54.
In other words, the pin insertion hole 34 a is provided with an R shape that widens the incoming diameter on the upper surface side of the lock plate 34 that is the receiving side opening of the pin 54.

As shown in FIG. 4, the transmission member 27 in the present embodiment is composed of a rod member that is long in the front-rear direction. As the transmission member 27, a wire having some flexibility can be used as long as it can transmit a tensile force to the slider portion 56c.

<Operation of lock / unlock device>
Next, the operation of the lock / unlock device 50 when the usage mode of the vacuum cleaner 100 is changed from the handy type shown in FIG. 2 to the stick type shown in FIG. 1 will be described.
In the handy type usage mode shown in FIG. 2, the length of the stretchable pipe 20 extending backward from the cleaner body 1 is shortened, and the stretchable pipe 20 is accommodated in the pipe case portion 13 over substantially the entire length.

At this time, mainly described with reference to FIG. 6, the lock / unlock device 50 is not shown, but in the locked state, the tip of the pin 54 is locked via the pin insertion hole 21 c of the pipe member 21. The plate 34 is fitted in the pin insertion hole 34a. Further, the pin 54 is urged downward by the spring 55, and the locked state of the pin 54 fitted in the pin insertion hole 34a is maintained.
As a result, movement of the expansion / contraction pipe 20 in the pipe case portion 13 in the front-rear direction is prohibited, so that the extension length of the expansion / contraction pipe 20 relative to the cleaner body 1 is fixed to a certain length.

Next, referring mainly to FIG. 7, when the user's finger pulls the trigger 39 backward, the distal end portion of the protruding piece 39 c of the trigger 39 moves the guide member 23 b of the second insertion member 23 engaged behind. Move to. Incidentally, the user pulls the trigger 39 backward with a force that resists the biasing force of the spring 55 (see FIG. 6).
Thereby, the rear end attachment portion 23a of the second insertion member 23 connected to the rear end of the guide member 23b pulls the transmission member 27 rearward. The distal end mounting portion 56g (see FIG. 10A) of the locked portion 51 (slider portion 56c) connected to the distal end of the transmission member 27 receives the tensile force and moves rearward.

  The curved portion 56f (see FIG. 6) of the slider portion 56c that moves backward pushes the tapered surface S2 (see FIG. 6) of the movable portion 56b (see FIG. 6) backward. As a result, the curved portion 56f slides on the tapered surface S2 so as to be positioned below the tapered surface S2. The movable portion 56b that supports the pin 54 moves upward. As shown in FIG. 6, the pin 54 is released from the pin insertion hole 34 a of the lock plate 34 to release the locked state. The telescopic pipe 20 can move in the front-rear direction within the pipe case portion 13.

  Next, mainly referring to FIG. 7, the user cleans the telescopic pipe 20 that has grasped the first handle 30 in a state where the trigger 39 is pulled and is movable in the front-rear direction in the pipe case portion 13. Pull out from the main body 1. Then, the user opens the trigger 39 and further pulls out the expansion pipe 20 when the length of the extended expansion pipe 20 approaches the expansion pipe 20 suitable for use as a stick type.

  At this time, the pin 54 shown in FIG. 6 moves backward in the pipe case portion 13 while being biased downward by the spring 55. When the pin 54 reaches the pin insertion hole 34 a of the lock plate 34, the pin 54 is fitted into the pin insertion hole 34 a by the biasing force of the spring 55. Thereby, the expansion-contraction pipe 20 is fixed to the length of the usage mode in the stick type shown in FIG.

≪Usage of electric vacuum cleaner≫

FIG. 12 is a perspective view when the vacuum cleaner 100 is attached to the charging stand 70 in a stick state. FIG. 13 is a side view when the vacuum cleaner 100 is self-supported in a stick state. FIG. 14 is a side view showing the handy vacuum cleaner 100 to which the futon inlet 6 is attached. FIG. 15 is a side view showing the handy vacuum cleaner 100 using the rotating brush 80. FIG. 16 is a side view showing the electric vacuum cleaner in a stick state to which the power brush type suction body 3a is attached. FIG. 17 is a side view showing a use state in which another mouthpiece (applied mouthpiece 5) is attached.

As shown in FIG. 11, the charging stand 70 to which the handy vacuum cleaner 100 is attached includes a base portion 71, a stand portion 72, and a charging stand terminal portion (not shown).
The base 71 has a substantially rectangular mounting surface 71a on which the suction body 3 (see FIG. 1) is mounted. The base 71 is provided with an applied suction body fixing protrusion 71c to which the applied suction body 5 (see FIG. 17) and the like are detachably attached. When the applied mouthpiece 5 is attached, it can be stored by being inserted into the applied mouthpiece fixing protrusion 71c.

  The stand portion 72 extends upward in the vertical direction (vertical direction) from the rear end portion of the base portion 71. In addition, the stand part 72 is formed such that the upper part from the center in the vertical direction is thicker in the front-rear direction than the lower part. The stand part 72 is detachable from the base part 71.

  The charging base terminal portion is provided on the upper surface 72a of the stand portion 72, and is connected to a main body terminal portion (not shown) provided in the storage battery case portion 12 of the vacuum cleaner main body 1 to be described later. It can be charged.

Moreover, as shown in FIG. 12, the vacuum cleaner 100 can be charged even in a stick state. At this time, by mounting the suction body 3 and setting the vacuum cleaner 100, the lower surface of the suction body 3 is supported by the mounting surface 71 a of the base portion 71, so that the vacuum cleaner 100 is supported more stably. can do.
In addition, the charging stand 70 can be used as a stand for storing the cleaner body 1 even when the storage battery 60 is not charged.

Next, the self-supporting structure of the vacuum cleaner 100 will be described.
As shown in FIG. 13, as described above, the mouthpiece 3 includes the mouthpiece case 3a and the mouthpiece joint 3b.

  The inlet joint 3b includes a first connection pipe 3g that is rotatably connected to the inlet case 3a in the front-rear direction, and a second connection that is rotatably connected to the first connection pipe 3g in the left-right direction. A tube 3h.

The first connecting pipe 3g is configured to be rotatable from a substantially parallel state to a substantially vertical state (up and down direction) with respect to the floor surface (cleaning surface).
The second connection pipe 3h is configured to be turnable in the left-right direction with respect to the first connection pipe 3g. Thereby, for example, the cleaner body 1 can be tilted toward a state substantially parallel to the floor surface from a state in which the cleaner body 1 is substantially perpendicular to the floor surface.

  The second connection pipe 3h is provided with a power supply terminal (not shown) that receives power from the storage battery 60. Moreover, the 2nd connection pipe 3h is formed with the connection pipe (illustration omitted) connected with the suction inlet 15 of the cleaner body 1.

  Further, a projection 3m is formed at the tip of the second connection pipe 3h. Further, the tip of the protrusion 3m abuts on the upper surface of the suction case 3a. Further, when the suction joint 3b rises forward, the tip of the protrusion 3m abuts against the upper surface of the suction case 3a, so that the forward rotation of the suction joint 3b is restricted. In the vacuum cleaner 100, when the rotation of the suction joint 3b is restricted, the center of gravity Ga of the cleaner body 1 is positioned on the vertical line passing through the axis of the suction joint 3b (first connection pipe 3g). Yes. Thereby, the vacuum cleaner 100 can be made independent.

Next, the vacuum cleaner 100 using the futon inlet 6 will be described.
As shown in FIG. 14, the futon inlet 6 includes an inlet body 6a, a rotating body 6b, and a joint 6c.
The futon inlet 6 is configured to have a shallow angle, for example, 15 degrees with respect to the lower surface of the inlet body 6a when the joint 6c is laid on the floor surface (surface to be cleaned).
Thereby, when cleaning a futon with a handy type, it becomes possible to move the cleaner main body 1 back and forth smoothly.
Moreover, although illustration is abbreviate | omitted, the futon can also be cleaned with a stick type by extending the telescopic pipe 20.

Next, the rotating brush 80 that is rotatably attached to the cleaner body 1 will be described.
As shown in FIG. 15, the rotary brush 80 includes a rotary base 81 a that is rotatably supported at the front end of the cleaner body 1, and a brush portion 81 b that is implanted in the rotary base 81 a. ing.
As shown in FIG. 2, the rotation base 81 a is rotated below the suction port 15 in the housed state.
When the cleaner body 1 is used as a handy type, the brush 81 b can be brought into contact with a flat cleaning surface by rotating the rotary brush 80.

  Next, as shown in FIG. 16, in the vacuum cleaner 100 to which the power brush type suction body 3a is attached, it is used in a stick state and the vacuum cleaner main body 1 is laid down, so that it is placed under a bed or a sofa. It becomes possible to clean the floor surface.

Moreover, as shown in FIG. 17, the vacuum cleaner 100 can also be used with the applied suction body 5 attached.
The tip of the applied suction body 5 has a shape smaller than that of the rotating brush 80, for example, so that a narrow place can be cleaned. Moreover, in order to clean the high place which cannot reach with a handy type | mold, it becomes the structure which can expand-contract length.

≪Effects of electric vacuum cleaner≫
Next, the effect which the vacuum cleaner 100 which concerns on this embodiment show | plays is demonstrated.
In the vacuum cleaner 100, the first handle 30 is disposed at the end of the extension pipe 20 provided in an extendable direction with respect to the cleaner body 1, and the extension pipe 20 is partially attached to the cleaner body 1 side. A second handle having a cylindrical portion 22a included therein as a grip portion is disposed.
Thereby, when using the vacuum cleaner 100 in a handy state, the first handle 30 can be brought close to the center of gravity Ga of the vacuum cleaner 100 (see FIG. 2). Also, when using the second handle 33 in the handy state, the second handle 33 is approaching the center of gravity Ga (see FIG. 2). Therefore, according to the vacuum cleaner 100, a big burden is not applied to a user's finger.

  Further, in the vacuum cleaner 100, at least a part of the storage battery 60, at least a part of the electric blower 40, and at least a part of the main body substrate 44 are positioned below the cylindrical part 22 a as a grip part of the second handle 33. In addition, the position of the insertion port 33a in the front-rear direction is set. Thereby, as shown in FIG. 2, the gravity center Ga of the vacuum cleaner 100 is located near the lower part of the cylindrical portion 22a held by the user. Therefore, the burden of the load applied to the user's finger is reduced.

Moreover, in the vacuum cleaner 100, as shown in FIG. 3, the central axis Ax1 of the suction inlet 15 is arrange | positioned on the front extension of central axis Ax2 of the expansion-contraction pipe 20 mentioned later by planar view of the cleaner body 1. As shown in FIG. Yes. As shown in FIG. 4, the central axis Ax1 of the suction port 15 is arranged so as to be parallel to the central axis Ax2 below the central axis Ax2 of the telescopic pipe 20 in a side view of the cleaner body 1. Yes.
Therefore, according to the vacuum cleaner 100, the first handle 30 attached to the rear part of the expansion pipe 20 is gripped, and the operability when the suction port 15 is directed to the floor side is excellent.

Further, as shown in FIG. 2, the central axis Ax5 extending in the direction of the long hole serving as the insertion port 33a of the user's finger is located on the rear extension line of the central axis Ax1 of the suction port 15 of the cleaner body 1.
Therefore, according to the vacuum cleaner 100, the operability when the second handle 33 is gripped and the suction port 15 is directed to the floor surface side is excellent.

In addition, when the vacuum cleaner 100 is used in a stick-type form, the center of gravity Ga of the vacuum cleaner 100 is not on hand but on the floor side, so cleaning can be performed without placing a heavy burden on the hand, Usability is improved.
Thus, the vacuum cleaner 100 can realize ease of use regardless of whether it is a handy type or a stick type.

  Moreover, according to this vacuum cleaner 100, since the trigger 39 which operates the lock / unlock device 50 of the telescopic pipe 20 constitutes the first handle 30, the length of the telescopic pipe 20 using the first handle 30 is long. Adjustment is extremely simple.

  Further, according to the vacuum cleaner 100, the operation button 31 a is arranged on the upper surface of the base grip portion 30 a constituting the first handle 30, so that the user can use the finger of the hand on the side holding the first handle 30. The electric operation of the vacuum cleaner 100 can be easily performed.

  In the electric vacuum cleaner 100, the switch board 36 linked to the operation button 31 a is disposed in the first handle 30. Further, since the switch board 36 is locked to the rib 35a provided on the lower surface side of the handle upper half 35 constituting the first handle 30, the mounting stability and reliability of the switch board 36 are excellent.

  Moreover, in this vacuum cleaner 100, since the switch board 36 is covered with the plate frame part 37b which has electrical insulation via the rib 35a, it is hard to receive the electrical influence from the outside.

  Moreover, in this vacuum cleaner 100, as shown in FIG. 6, the to-be-latched part 51 is provided in the front-end part of the expansion-contraction pipe 20 (pipe member 21). By the way, in the conventional vacuum cleaner (for example, refer patent document 1), the extension length of a pipe member is locked by latching a pipe member in the rear-end part of a cleaner body. However, in the conventional vacuum cleaner, when the pipe member is pushed into the vacuum cleaner main body, the tip of the pipe member becomes free in the vacuum cleaner main body.

  On the other hand, in the vacuum cleaner 100 of this embodiment, since the to-be-latched part 51 is provided in the front-end part of the expansion-contraction pipe 20 (pipe member 21), unlike the conventional vacuum cleaner, the expansion-contraction pipe 20 ( The front end of the pipe member 21) is prevented from rattling.

  Moreover, in the vacuum cleaner 100 of this embodiment, while the to-be-latched part 51 is arrange | positioned only at the front-end part of the expansion-contraction pipe 20 (pipe member 21), the pin insertion hole 34a as the latching | locking part 52 is locked. A plurality of plates 34 are formed along the front-rear direction of the plate 34.

  By the way, in the conventional vacuum cleaner (for example, refer patent document 1), the some to-be-latched part (hole) is formed along the longitudinal direction of a pipe member. Therefore, the conventional vacuum cleaner has a problem that the locked portion (hole) of the pipe member is noticeable when the pipe member extends from the cleaner body. On the other hand, in the vacuum cleaner 100 of this embodiment, since the to-be-latched part 51 is arrange | positioned only at the front-end part of the expansion-contraction pipe 20 (pipe member 21), it can exhibit favorable design property.

Moreover, in the vacuum cleaner 100 of this embodiment, the pin insertion hole 34a (hole) is given the chamfering shape or R shape which expands an incoming diameter in the receiving side opening part of the pin 54. As shown in FIG.
Thereby, in the vacuum cleaner 100, the pin 54 is smoothly received into the pin insertion hole 34a (hole), and rattling of the expandable pipe 20 (pipe member 21) is prevented.

As mentioned above, although embodiment of this invention was described, this invention is not limited to above-described embodiment, In the range which does not deviate from the meaning of this invention, it can change variously.
The usage mode of the vacuum cleaner 100 is not limited to the two forms of the stick state shown in FIG. 1 and the handy state shown in FIG. 2, and can be used in an intermediate state between the handy state and the stick state.

  In the vacuum cleaner 100 of the above embodiment, the telescopic pipe 20 is hollow, but may be solid.

  Moreover, in the vacuum cleaner 100 of the said embodiment, although the pin insertion hole 34a as the latching | locking part 52 is formed with the hole which penetrates the lock plate 34, the latching | locking part 52 in this embodiment is bottomed. It can also be a hole.
