As can be seen from these figures, in the vacuum cleaner according to the present embodiment, the pivotal support 5 is formed on both sides of the distal end of the hand grip 3 formed at the distal end of the hose 31.
A suction port attachment 6 is detachably pivotally attached to the pivot portion 5, and a first position in which the suction port attachment 6 shown in FIG. 1 is in use and a non-use of the suction port attachment 6 shown in FIG. It rotates between the second position which is the state. The other configuration of the hand grip portion 3 is the same as the conventional one, and the upper portion has an operating portion for adjusting the suction force of the blower for sucking dust, turning on and off the power brush, and a tip portion. Is provided with a lever mechanism 32 for connecting and disconnecting an extension pipe connected thereto, and a joint spring portion having a female structure as a power supply connection terminal is provided on a distal end surface for connecting the extension pipe.

As shown in FIGS. 3 and 4, the pivot portion 5 has a locking boss 51 for pivotally supporting the suction port attachment 6, and the suction port attachments 6 on both sides thereof. Are formed on both side surfaces of the distal end portion of the hand grip portion 3 in a shape having an engagement concave portion 52 for positioning and holding at the first position and the second position, respectively. It is needless to say that the pivot portion 5 is not limited to the above-mentioned configuration, and various modifications are possible, for example, an engagement concave groove 53 may be used instead of the engagement concave portion 52 as shown in FIG.

On the other hand, the suction port attachment 6 includes a brush attachment shown in FIG. 6 and a clearance suction port shown in FIG. 7, both of which are formed in a U-shaped frame as shown. A locking hole 62 in which the locking boss 51 is fitted is formed on both side surfaces on the open end side of the frame body 61, and an engagement dowel 63 is formed in an upper portion thereof to be engaged with the engagement recess 52. In addition, a covering plate 64 is provided at a position on the closed end side of the attachment frame body 61 which is recessed from the U-shaped end surface, and one surface of the covering plate 64 has a distal end portion of the hand grip portion 3 or the like. A terminal fitting projection 65 that fits into a power supply connection terminal formed at the end of the extension pipe 4 is formed. As is clear from FIGS. 6 and 7, the brush attachment has a brush 66 implanted at the end of the suction port. On the other hand, the bristle portion is not formed in the gap suction port, and the brush portion is formed of a plate material.

The attachment of the suction port attachment 6 to the distal end of the hand grip 3 or to the pivot 5 formed on both sides of the distal end of the extension pipe 4 is performed by slightly opening and opening the open end of the attachment frame 61. Boss 51 for locking in stop hole 62
Can be easily attached as shown in FIG. 1, FIG. 2 and FIG. 8 simply by fitting them together, and thus can be easily removed. In addition, reference numeral 42 in FIG.
The button for operating the lever mechanism for separating the power brush is shown at the tip of the camera.

When the suction port attachment 6 is used, a tip part is removed from the hand grip part 3 and the extension pipe 4, and a pivot part 5 formed on both the tip part of the hand grip part 3 and the tip end of the extension pipe 4 is formed. In a state where the suction port attachment 6 is attached and the locking boss 51 of the pivot portion 5 is fitted in the locking hole 62 of the suction port attachment 6, as shown in FIG. The attachment 6 is turned to the first position. That is, the closed end side of the suction port attachment 6 is raised above the distal end portion of the hand grip portion 3 and the distal end portion of the extension pipe 4, and the terminal fitting protrusion 65 is formed at the distal end portion of the hand grip portion 3 and the distal end portion of the extension pipe 4. Fit to the joint spring part. At this time, the engagement dowel 63 formed in the suction port attachment 6 is engaged with the engagement recess 52. Thereby, the suction port attachment 6 is positioned and fixed at the first position which is the use position.
Therefore, when used in this state, the suction port attachment 6 can be configured such that the terminal fitting projection 65 and the joint spring portion are fitted together, and the engagement dowel 63 and the engagement recess 52 are fitted together. It is securely fixed to the tip of the extension pipe 4 so that there is no possibility that it will come off during use. Further, dust sucked from the suction port attachment 6 is prevented from entering the joint spring portion, and contact failure of the power supply connection portion is completely eliminated.

On the other hand, in the case where the extension pipe 4 or the power brush is connected to the tip of the extension pipe 4 without using the suction port attachment 6 but at the end of the grip portion 3 at hand,
The suction port attachment 6 is turned to the non-use second position shown in FIG. 2 and FIG. 8C. That is, the closed end side of the suction port attachment 6 is moved below the hand grip portion 3 and the extension pipe 4, and the engagement dowel 63 formed in the suction port attachment 6 is engaged with the engagement recess 52.
In this state, the extension pipe 4 is
Alternatively, a power brush is connected to the end of the extension pipe 4 for cleaning. At this time, the suction port attachment 6 is securely fixed to the distal end portion of the hand grip portion 3 and the lower end portion of the extension pipe 4 by the engagement of the engaging dowel 63 and the engaging concave portion 52, so that the inlet attachment 6 becomes an obstacle during cleaning. It can be cleaned without.

As described above, the suction port attachment 6 according to the present embodiment includes the distal end portion of the hand grip portion 3 and the extension pipe 4.
Cleaning with a power brush can be performed with the tip attached to the end of the grip, and there is no need to attach or remove the suction port attachment 6 to or from the tip of the grip portion 3 or the extension pipe 4 every time cleaning is performed. The usability of the machine becomes very good.

[0019]

As described above, according to the present invention, the attachment can always be kept attached to the hand grip portion or the extension pipe, and there is no need to end the attachment, so that no storage space is required. This makes it possible to make the main body of the vacuum cleaner compact, and eliminates the trouble of inserting and removing the attachment, thereby improving the usability. Further, when the attachment is not used, the attachment pivots to the side opposite to the one side on which the lever mechanism is disposed, so that there is an effect that the operation of the lever mechanism is not hindered when not used.
