[0007]
In the present embodiment, the cleaner body 4 is engaged with a holding base 5 that slides on the operation rod 3. Between holding base 5 and the operation rod 3, holding stand 5 lock means for fixing on the operation rod 3 is provided, the holder 5 is held in position on the operation rod 3.
The lock Teto are provided a plurality at any position on the operation rod 3. For example groove 31a on the operation rod 3 shown in FIGS. 1 and 2, 31b is part of the locking means, b Kkureba 8 provided rotatably around a pin 8b on the holding base 5 is the groove The holding stand 5 is fixed on the operating rod 3 by meshing with 31a or 31b. Lock Clever 8, spring because it is elastically biased in a direction to fit all times the groove 31a in the (not shown), the meshing state of the Lock clay bar 8 opposite to the urging direction of the spring It can be released by operating in the direction.
When moving along the cleaner main body 4 to the operation rod 3, as described above to release the Lock clay bar 8, it is moved with the gripper 62. Thereby, the cleaner body 4 can be easily moved together with the holding base 5 and can be fixed by engaging the lock lever 8 with the other recess 31b. Therefore, the vacuum cleaner body 4 can be enclosed in a multi-stage position by adding the recesses 31a and 31b to appropriate positions. The lock means, the shoe having a frictional force engages the holder 5 or may be a method of tightening the operating rod 3 periphery. In this case, when the cleaner body 4 is moved, the shoe is loosened and moved. According to this, the vacuum cleaner main body 4 can be fixed at a desired position without steps without using the recesses 31a and 31b.
By moving the cleaner body 4 to a predetermined position in this way, when cleaning the floor surface, the cleaner body 4 is fixed to the intake port 1 side, the center of gravity is on the floor side, and as shown in FIG. Or, when cleaning a deep place, it can be used efficiently by moving to the handle portion 2 side to lengthen the space between the vacuum cleaner main body 4 and the intake port portion 1 and improve usability and convenience.
At this time, the handle portion 2 is rotated to a position where it does not come into contact with the floor, so that it can be efficiently cleaned even in a narrow space. In particular, by attaching the vacuum cleaner main body 4 having a small and lightweight cyclone type dust collecting device 6 so as to be slidable, the load is reduced even if the cleaner body 4 is moved to the handle portion 2 side, and a comfortable usability can be obtained. .
[0008]
Next, a structure for attaching / detaching the cleaner body 4 to / from the holding base 5 will be described. In FIG. 2, a convex portion 6 a protruding from the lower end of the cleaner body 4 is engaged with a concave portion 5 a provided at the lower end of the holding base 5, and a holding lever 9 provided rotatably at the upper end portion of the cleaner body 4 is The vacuum cleaner body 4 is always elastically biased downward and meshes with the convex portion 5b provided at the upper end of the holding base 5, whereby the vacuum cleaner main body 4 has the concave portion 5a and the convex portion 6a at the lower end thereof. The convex portion 5b and the holding lever 9 are engaged with each other at the upper end portion and fixed to the holding base 5. Thus, the cleaner main body 4 and the holding base 5 slide together in the axial direction on the operation rod 3.
Further, by releasing the holding lever 9 to remove the cleaner body 4 from the holding stand 5 and removing one end of the intake pipe 7 from the intake port 1, the vacuum cleaner is separated from the operation rod 3 and the intake port 1. The main body 4 alone can be used as a vacuum cleaner. In other words, it can be used as a handy type for cleaning high places or automobiles.
On the other hand, the holding base 5 is always urged upward by a belt-like spring 10, in this case, in the direction of the handle portion 2. That is, one spring 10 is locked to the cleaner body 4, here the holding stand 5, and the other end is wound around the rotating wheel portion 11, and urges the cleaner body 4 toward the handle portion 2. The spring 10 itself is covered with a cover 31c that constitutes the outer shell of the operation rod 3 to prevent the spring 10 from being exposed and touching or damaging a person's finger and maintaining aesthetics.
[0009]
The spring 10 is a constant load spring and biases a constant load. The biasing force of the spring 10 is set to be substantially equal to or smaller young interference, the weight of the suspending body made of the cleaner main body 4 and the holder 5. Accordingly, the cleaner body 4 can be automatically moved in the direction of the handle portion 2 by the urging force of the spring 10 by removing the lock lever 8 and tilting the operating rod 3. There is no need for a person to lift the operability and convenience.
Further, vacuum cleaner when the main body 4 moves in a counter-handle unit 2 direction counter handle the weight of the object to be suspended body such as the cleaner main body 4 Repetitive operation rod 3 by opening the lock lever 8 just stand vertically Operation in the direction of section 2 is improved and operability is improved. In addition, the moving speed of the cleaner main body 4 varies depending on the degree of inclination of the operation rod 3 because it moves with a constant load corresponding to the difference between the biasing force of the spring 10 and the load of the suspended body such as the cleaner main body 4. In addition, during the movement period of the cleaner body 4, it moves smoothly at a constant speed and does not cause a sense of crisis or discomfort. Further, when the cleaner body 4 is moved by hand, the load of the cleaner body 4 is canceled by the spring 10, so that the force for moving the cleaner body 4 is small and the operability is improved.
Further, in order to fix the movement of the cleaner body 4 along the operation rod 3, the spring 10 may be held and fixed so as to restrain the movement of the spring 10. Thereby, since the movement of the spring 10 is prevented, the cleaner body 4 can be fixed.
Further, as shown in FIG. 2 (a), the operation rod 3 may have a double structure of a hollow movement operation rod 31 and a fixed operation rod 32 that is slidably fitted into the hollow portion of the movement operation rod 31. Good. Thereby, the operation rod 3 is configured to be extendable. FIG. 2A is a state diagram in which the operating rod 3 is extended, and a moving operating rod 31 indicated by a broken line shows a state in which the moving operating rod 3 is stored on the intake port 1 side. The outer periphery of the fixed operating rod 32 and the moving operating rod 31 are configured to be able to slide smoothly via the sliding members 33a and 33b. The fixing of the move operation rod 31 and the fixed operating rod 32 may be locked at a predetermined length provided lock means (not shown) in place. Thereby, it can be used in a state where the handle portion 2 is set at an appropriate position, and the electric vacuum cleaner can be stored and stored with a reduced overall length.
[0010]
The vacuum cleaner body 4 and the holding stand 5 are slidably held on the outer periphery of the moving operation rod 31 and on the outer periphery of the fixed operation rod 32 by the sliding member 12 such as a bearing (see FIG. 2B). The lower end of the fixing operation rod 32 is detachably locked by being fitted and fixed to the second connection pipe 14 of the intake port portion 1 with a taper, while the intake port portion 1 is spherically connected to the first connection tube 13. The first connecting pipe 13 is rotatably connected in the XY direction by the sliding portion 13a, and the first connecting pipe 13 is rotatably connected in the PQ direction (see FIG. 1A) by the second connecting pipe 14 and the rotating shaft 14a. However, it is preferable that the air inlet 1 is configured to be freely rotatable in the XY and PQ directions with respect to the operating rod 3.
The connection portion of the intake pipe 7 to the intake port portion 1 may be anywhere as long as it is a portion that communicates with the intake port 1a of the intake port portion 1. However, as described above, the intake port portion 1 and the operating rod 3 are XY and Since it rotates in the PQ direction, it is desirable to connect the intake pipe 7 to the second connecting pipe 14 that is movable integrally with the operation rod 3. Thereby, the intake pipe 7 is only expanded and contracted by the movement of the cleaner 4, and fatigue and breakage due to twisting and bending are reduced. In the example shown in FIG. 2, the second connecting pipe 14 is connected to the first connecting pipe 13, but in this case, when the operating rod 3 is movable in the XY direction, the first connecting pipe 14 is connected. Since it swings integrally with the tube 13, fatigue and breakage due to twisting and bending in this direction are reduced.
