Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a connecting pipe section that connects a vacuum cleaner main body and a hose section.
This invention relates to a floor movable vacuum cleaner that is rotatable relative to the vacuum cleaner body.

Structure of a conventional example and its problems FIG. 1 shows a conventional floor movable vacuum cleaner of this kind. That is, a vacuum cleaner main body 1 has a pair of rear wheels 2 that are rotatable in the front and rear directions, and A flexible wheel 3 is provided in front of the rear wheel 2, and a dust collection lid 4 for opening and closing a dust collection part (not shown) is provided above the vacuum cleaner main body 1. A connecting pipe 5 is attached which is rotatable in a substantially horizontal direction, and communicates between the hose 6 and the dust collecting section. A main body handle 7 is provided at the front of the vacuum cleaner main body 1, so that the vacuum cleaner main body 1 can be carried.

By the way, in the case where the hose 6 and the dust collecting section are connected through the horizontally rotatable connecting pipe 5, the hose 6 often moves in any direction through 360 degrees during cleaning. It is located in a position that covers the main body handle 7, and becomes an obstacle when trying to move the vacuum cleaner main body 1 by holding the main body handle 7, and has the disadvantage that the main body grip 7 must be held after moving the hose 6 each time. OBJECTS OF THE INVENTION The present invention solves these conventional drawbacks and allows the main body of the vacuum cleaner to be moved by freely holding the main body handle regardless of the position of the hose.

Structure of the Invention The present invention provides a method in which a connecting pipe section that communicates the dust collecting section of the vacuum cleaner body with a hose is rotatable in a horizontal direction with respect to the vacuum cleaner main body, and a main body handle is provided on this connecting pipe section. This makes it easy to move the vacuum cleaner body.

DESCRIPTION OF EMBODIMENTS The following embodiments will be described with reference to the accompanying drawings. Figures 2 to 7 show examples implemented in floor moving vacuum cleaners. A bumper 13 formed of 13 is held between a lower body 14 fixed below. Reference numeral 15 denotes a dust collection box that is detachably attached to the dust collection box storage section 16 on the main body 11, and has an open end and is equipped with a filter device 17 that can be attached and detached. A dust box handle 2o is provided. 2
Reference numeral 1 designates an intake robin that rotatably and slidably maintains airtightness with the connecting pipe 18, and is attached to the mounting plate 22 so as to maintain airtightness with the dust collection box 16.

23Ii connecting tube cover, which has an elbow-shaped connecting tube 18 fixed at the approximate center with a screw 24, and rotatably fits into the approximately circular fitting hole 24 formed on the main body 11. A retaining claw 26 is engaged with the upper body 11 to prevent it from coming off. The connecting tube cover 23 is provided with a hose hole 27 through which a hose 26 connected to one end of the connecting tube 18 is passed, and a handle storage portion 28 is formed on the outer surface opposite to the hose hole 27 to accommodate a handle 29. By rotating the handle shaft 30 into the shaft hole 31, the handle 29 can be freely stored and turned upside down with respect to the connecting tube cover 23', and by lifting the handle 29, the entire vacuum cleaner can be opened. Can be moved. hose 2
6 is made of a flexible soft material and can be inserted and stored in the end tube storage section 33.
2, by rotating the connecting tube cover 23, the hose 26 can be wrapped around the outer surface of the substantially truncated conical upper body 11 and stored. Reference numeral 34 denotes a flexible wheel attached to the lower surface of the lower body 14, which is composed of a wheel cover 36 rotatably attached to the axle 36 of the lower body 14, and a wheel 37 rotatably provided on the wheel cover 36. wheel 34
is equipped with three or more.

Reference numeral 38 denotes a storage box with an opening on the top surface which is detachably attached below the vacuum cleaner body, and can be freely attached to the vacuum cleaner body with a buckle 39. A fitting boss 40 is formed to protrude upward from the bottom surface 41 of the storage box 38, and is fitted into the inner diameter portion of the tubular extension tube 42 to hold the extension tube 42 in an upright state. Reference numeral 43 designates an extension tube fitting hole recessed in the lower surface 44 of the lower main body 14, which is formed using a space inside the vacuum cleaner main body. The extension tube 42 is formed so that one end of the extension tube 42 can be inserted therein. 46 is a floor nozzle stored in the storage box 39.

In the above configuration, when the hose 26 is pulled, the connecting pipe cover 23 can rotate with respect to the main body 11, but since the handle 29 is also provided on the connecting pipe cover 23, the hose 26 can be rotated with respect to the main body 11.
It is designed so that it always rotates together with the transfer button 1 of 6.

In the above configuration, the handle 29 is provided in the connecting pipe cover 23 so that it can be stored in an inverted position, but it may be integrated with the connecting pipe cover 23 or formed on the connecting pipe 18 itself. Any configuration in which the handle rotates is sufficient.

Effects of the Invention As is clear from the above embodiments, in the present invention, the connecting pipe section connecting the vacuum cleaner body and the hose section is horizontally rotatable, and the connecting pipe section is provided with a handle of the vacuum cleaner main body. No matter which position the hose rotates, the handle can be easily held and the vacuum cleaner body can be moved smoothly.

In addition, since the handle and the vacuum cleaner body can rotate freely relative to each other, even if the vacuum cleaner body comes into contact with an obstacle while moving the vacuum cleaner body by the handle, the connecting tube rotates and does not cause a shock. Because it softens, it also has the effect of reducing the strain on your arms.
