Abstract

PURPOSE:To enable a cleaner to stand on its own bottom by providing a pipe member connected to the lower portion of a cleaner body, a hollow spherical portion connected to the pipe member, a suction section for nipping the spherical portion with upper and lower cabinets, a means for fitting the pipe member in the upper cabinet and a means for locking the spherical portion in the lower cabinet. CONSTITUTION:When a cleaner is adapted to stand on its own bottom to be housed, a cleaner body 1 is pushed a little hard forward to remove a projecting rib 13 of a lower cabinet 6 from a groove 10. When the cleaner body 1 is further pushed forward, the projecting rib 13 rides over a peripheral wall 10a of a spherical section 8 to abut against and lock the end 112 of the wall, and a projection 14 of the front face of a pipe member 15 fits in a fitting recess 15a in a housing section 15 of an upper cabinet 7 to prevent the cleaner body 1 from falling down back and forth or left and right. The cleaner body 1 can stand on its own bottom stably together with these actions without swinging back and forth, left and right.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a free-standing vertical vacuum cleaner that is lightweight and takes up little storage space.

BACKGROUND OF THE INVENTION Recently, vertical vacuum cleaners have been developed because they are compact and do not require much storage space, and there is no need to worry about adjusting tangled bellows hoses during cleaning.

A conventional vertical vacuum cleaner will be described below. FIG. 7 is a perspective view of a conventional vertical vacuum cleaner, FIG. 8 is a sectional view of a main part of a suction tool, and FIG. 9 is a perspective view of the vertical vacuum cleaner when it is stored independently.

2 is a vacuum cleaner body with a built-in electric air suction device, 2 is a floor suction device, and 3 is a handle with a handle 4 at the tip. Suction tool 2
The pipe member 5 is directly fitted into the vacuum cleaner main body 1, and the handle 3 is attached to the upper part of the vacuum cleaner main body 1.

In a vacuum cleaner having such a configuration, the vacuum cleaner body 1 can be swung back and forth, that is, in the direction of arrow A, or rotated in the direction of arrow B, while the suction tool 2 remains on the floor. It is very convenient to use. For this purpose, the tube member 5 in the suction tool 2 needs to be able to rotate and swing. In FIG. 8, 6 is a lower cabinet of the suction tool main body, 7 is an upper cabinet of the suction tool main body, and the suction tool main body is constructed by joining the lower cabinet 6 and the upper cabinet 7. 8 is a spherical portion provided at the tip of the tube member 5. The spherical part 8 is housed in a spherical casing formed in the lower cabinet 6 and the upper cabinet 7, and no gap is created between the outer wall of the spherical part 8 and the inner wall of the spherical casing to prevent air leakage. I'm there.

With the structure described above, the tube member 5 is swingable in the direction of arrow C, and comes into contact with the contact portion 9 of the upper cabinet 1-6 when brought to the frontmost position. Furthermore, the tube member 5 is rotatable over 360 degrees in the direction of the arrow.

Further, the vacuum cleaner of this example is constructed so that it can stand on its own as shown in FIG. That is, when the tube member 5 hits the abutting portion 9, the cleaner body tilts forward somewhat. The center of gravity of the vacuum cleaner body is located in front of the swing fulcrum position, that is, the position of the spherical part 8, so that it will not fall over even if the user releases the hand.

Among the problems that the invention aims to solve, the above-mentioned structure has the following problems. In other words, when the vacuum cleaner is in an upright position as shown in Figure 9, if the user carelessly hits the vacuum cleaner or the handle, the vacuum cleaner will lose its balance and easily fall over. It ends up. This happens when,
There is a possibility that the exterior of the vacuum cleaner or the floor may be scratched, or the vacuum cleaner itself may be damaged.

In addition, as shown in FIG. 7, the vacuum cleaner body 1 and handle 3 are
If the vacuum cleaner can be rotated 360 degrees in any direction, the center of gravity of the vacuum cleaner body may shift to the rear if the rotation angle is outside a predetermined range. Even if the vacuum cleaner is stood up until it hits the pipe member 5 or the contact part 9 as described above, if for some reason the vacuum cleaner body rotates significantly, the forward leaning posture will collapse and the center of gravity of the vacuum cleaner body will shift to the rear. As a result, it becomes extremely unstable and easily falls over.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a vacuum cleaner that is self-supporting and does not easily fall over.

Means for Solving the Problems The present invention provides a fitting means at the abutting portion between the pipe member and the upper cabinet of the suction tool in order to prevent the vertical vacuum cleaner from falling to the left or right when it stands on its own. In order to prevent the suction device from falling back and forth, locking means are provided on the spherical portion connected to the tube member and on the lower cabinet of the suction device.

Effect: With the above configuration, when the vertical vacuum cleaner is made to stand on its own, the recess or protrusion provided on the pipe member and the protrusion or recess provided on the abutting surface of the pipe member storage portion of the upper cabinet fit together. At the same time, by locking the concave or convex part provided on the lower cabinet abutting part of the spherical part with the convex part or concave part provided on the spherical part volume part of the lower cabinet, the vertical vacuum cleaner can be moved forward, backward, left or right. Prevents it from falling and makes it stable and independent.

Embodiment FIG. 1 is a perspective view of a pipe member of a vertical vacuum cleaner according to an embodiment of the present invention, seen from the back, FIG. 2 is a plan view of the lower cabinet, and FIG. 3 is a diagram of FIG. - It is a sectional view of the main part along the A line, Fig. 4 is a diagram of the installation state of the pipe member in the lower cabinet as seen from the top, Fig. 5 is an enlarged view of the main part of the left and right fall prevention mechanism, and Fig. 6 is a vacuum cleaner. This is a self-supporting diagram.

and the fitting recess 15a provided in the accommodating part 15 of the upper cabinet 7, which prevents the vacuum cleaner main body l from tipping back and forth or from side to side, and these actions combined together,
The vacuum cleaner main body 1 can stably stand on its own without swinging back and forth and left and right.

Note that the protrusion 14 of the tube member 5 may be provided so as to protrude from the tube member 5, but it may also have a structure in which its upper surface is flush with the tube member 5 and fitting grooves 16 are provided on the left and right sides thereof. . With the latter structure, the fitting surfaces of the protrusion 14 and the fitting groove 16 and the accommodating part 15 of the upper cabinet 7 widen, and the fitting groove 16 clamps the peripheral wall of the accommodating part 15, so that the fall prevention effect is improved. High (can be.

When using a vacuum cleaner, the protruding rib 13 of the lower cabinet 6 slides through the groove 10 provided around the entire circumference of the lower surface of the spherical part 8, so there is no problem even if the suction tool 2 is moved up, down, left, right, etc. It's fleeting. The airtightness is ensured over almost the entire circumference of the storage section 12 of the lower cabinet 6, on the sliding surface between the vertical wall 12a provided in parallel and the peripheral wall section 10a of the spherical section 8, etc., and on the peripheral wall of the storage section 15 of the upper cabinet 7 and the spherical surface. It is held by the sliding surface with the upper peripheral wall of the part 8. As another example, a protrusion may be provided in place of the recess 15a of the housing portion 15 of the upper cabinet 7, and a recess that fits with the protrusion may be provided in place of the protrusion 14 of the tube member 5. Further, a wide groove is provided in place of the protruding rib 13 of the lower cabinet 6, the peripheral wall part 11 is made a bulge in place of the groove 10 of the spherical part 8, and the outer edge of the groove provided in place of the protruding rib 13 is provided. The portion and the bulging portion may be formed to engage with each other, or these may be combined with the above-described embodiments.

Effects of the Invention The present invention allows the vacuum cleaner to easily stand on its own by using means for fitting the pipe member and the upper cabinet of the suction device, and means for locking the spherical part and the lower cabinet throat. By virtue of these fitting means and locking means, the main body of the vacuum cleaner does not swing, stands stably on its own, and does not fall easily. In addition, since it is difficult to fall over, it does not damage the floor or the vacuum cleaner itself when it falls, improving its durability.
