Abstract

PURPOSE: To insert and house a fluxible pipe on a rigid pipe by providing stoppers which hook the flexible pipe at the base end to the rigid pipe at the end in such a way that the flexible pipe is sealed in the rigid pipe. CONSTITUTION: A rigid pipe 11 is provided with a drawing stopper 12 at the end and an insertion stopper 13 in the middle, where the drawing stopper 12 is shaped like a flange facing inward and the insertion stopper 13 protrudes inward. A flexible pipe 15 is provided with an end stopper 16 at the base end and an insertion stopper 17 at the other end, both stoppers facing outward. The flexible pipe 15 is hooked to, and sealed by, the rigid pipe 11 at the drawing stopper 12 and the end stopper 16, to allow the flexible pipe 15 to extend from the rigid pipe 11 for cleaning services. The flexible pipe 15 can be housed in the rigid pipe 11 by hooking the end stopper 16 at its base end to the insertion stopper 16 at the middle of the longitudinal direction in the rigid pipe 11 and, at the same time, by inserting the flexible pipe 15, while shrinking it, into the rigid pipe until the insertion stopper 17 is hooked to the drawing stopper 12.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to suction (vacuum) for cleaning the interior (indoor) floor of a barber shop, beauty salon, sewing room, office, store, etc. outdoors (generally outdoors). The present invention relates to an improvement of a suction pipe (suction piping system) in a stationary suction (vacuum) cleaning device that is performed via a suction nozzle connected to a tip portion of a suction pipe extending from a dust collector.

[0002]

2. Description of the Related Art Conventionally, a suction pipe in a suction cleaning device of this type has a fixed pipe (including a duct) extending from an outdoor suction dust collector to a chamber wall (including a floor wall) and a fixed pipe having a base end portion. It is composed of a flexible tube that is detachably connected to the distal end of the flexible tube and a nozzle tube (extension tube) with a suction nozzle is connected to the distal end of the flexible tube. While moving the suction nozzle to an arbitrary position in the room within the range of the length, dust such as the floor in the room is sucked.

[0003]

However, in the conventional suction tube in which the fixed tube extending outside the room and the flexible tube extending inside the room are separably connected as described above, the flexible tube is provided in order to widen the cleaning range. If the length of the suction cleaning device is increased, a large space is required to store the flexible tube when the suction cleaning device is not used, and it is difficult to orderly store the flexible pipe.

In view of the above problems, the present invention is a suction device that can be stored neatly without providing a special storage space even if the length of the flexible tube that can extend inside the chamber is long. Intended to provide a tube.

[0005]

The suction pipe according to the present invention is basically a fixed pipe (including a duct) extending from a suction dust collector installed outdoors to a chamber wall, and a nozzle pipe with a suction nozzle at its tip. The flexible tube that connects the flexible tube is detachably connected through the tip of the fixed tube so that it can be inserted and removed (inserted and removed), and the tip of the fixed tube (tip region) or the chamber wall around the tip of the fixed tube and the base of the flexible tube. Inward (inward protrusion) or inward-like (protruding to the fixed pipe internal corresponding portion on the extension line of the fixed pipe) capable of simultaneously engaging the seals (airtightness) with each other at the end faces while making the stop engagement with each other. It has a structure with a pull-out stopper and an outward (outward protruding) end stopper.

The fixed tube may be provided with an inward insertion stopper at an intermediate portion in the axial direction, which is spaced from the distal end to the inner rear side, so that the end stopper at the proximal end of the flexible tube can stop-engage.

Further, the distal end of the flexible tube may be provided with an outward (outwardly projecting) insertion stopper capable of being stop-engaged with the distal end of the fixed tube including the drawer stopper or the chamber wall around the distal end of the fixed tube. it can.

[0008]

In the suction tube of the present invention, when cleaning the inside of the room, the flexible tube is stopped from the fixed tube, and the end stopper at the base end portion of the suction tube is engaged with the leading end portion of the fixed tube or the drawer stopper of the chamber wall portion around the distal end. At the end of cleaning, the flexible tube is inserted into the fixed tube until the tip is almost adjacent to the tip of the fixed tube, that is, the chamber wall around the tip of the fixed tube. To

When the insertion stopper is provided in the fixed tube, the above flexible tube can be inserted into the fixed tube until the end stopper at the base end portion engages with the stopper, and the distal end of the flexible tube can be inserted. When the insertion stopper is provided in the portion, the insertion stopper can be used until it stops-engages with the distal end portion of the fixed tube including the withdrawal stopper or the chamber wall portion around the distal end portion.

The flexible tube is generally inserted and stored in the fixed tube by a manual pushing method or a suction method using a suction force of a suction dust collector (in this case, the opening of the suction nozzle or the suction nozzle is removed). Open the opening at the tip of the nozzle tube or the opening at the tip of the flexible tube without the nozzle tube,
(These parts are closed with lids attached or separately prepared so that suction force effectively acts on the flexible tube.)
Automatic (including those that use a mainspring as a drive source) or a manual winch retracting method (in this case, the winch is installed in the inner part of the fixed tube, and the ropes extending from the winch winding cylinder are included in the fixed tube. It can be performed by connecting from the back side to the base end of the flexible tube), or by a combination of these methods.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The suction tube of the present invention can be implemented in the form shown in FIGS. 1 and 2, for example.

FIG. 1 shows an outline of the configuration of the first embodiment. The fixed pipe 11 extending from the outdoor suction dust collector to the chamber wall 20 is a straight line portion having a tip portion and an intermediate portion subsequent thereto. While it is provided with an inward flange (ring) -shaped drawer stopper 12 that is concentrically attached to the tip, it is equidistant around the axis in the middle part with a predetermined distance from the tip to the inner back side. It is provided with a plurality of inwardly projecting angular piece-shaped insertion stoppers 13 attached at intervals.

On the other hand, the flexible tube 15 which is inserted into and removed from the fixed tube 11 in the axial direction so that the nozzle tube 18 with the suction nozzle 19 is connected to the distal end of the flexible tube 15 has a smaller diameter than the fixed tube 11. It is formed of a flexible hose, and has a hard synthetic rubber outward flange (ring) -shaped end stopper 16 at the base end, and a tip end that detachably connects the nozzle tube 18,
An outwardly facing flange (ring) -shaped insertion stopper 17 is provided.

In the first embodiment, the flexible tube 15 is extended from the fixed tube 11 until the end stopper 16 at the base end of the flexible tube 15 is engaged with the pull-out stopper 12 at the tip of the fixed tube 11 at the same time as the seal engagement. While it is being pulled out while being drawn (shown by the solid line), it is used for cleaning the inside of the room, and when the cleaning of the room is finished, the flexible tube 15 is provided with the end stopper 16 at the base end in the axial middle of the fixed tube 11. While being engaged with the insertion stopper 13 of No. 1 at the same time, the insertion stopper 17 at the distal end is contracted and inserted into the fixed pipe 11 until the insertion stopper 17 at the distal end is engaged with the pull-out stopper 12 at the distal end of the fixed pipe 11 (and seal engagement). Put it in storage (shown in phantom).

As described above, the flexible tube 15 is inserted into the fixed tube 11 by a manual pushing method, a suction method using a suction force through a suction dust collector, a winch drawing method, or the like. It can be done by a method. When the flexible tube 15 is completely accommodated in the fixed tube 11, the sealing engagement between the insertion stopper 17 and the withdrawal stopper 12 and the cover of the distal end of the flexible tube 15 as in the suction system using the suction dust collector are performed. By closing with a kind, the suction tube can be completely closed at the wall of the chamber.

In the second embodiment, the flexible tube 15 is pulled out to a state (indicated by a solid line) in which the base end portion of the flexible tube 15 is left inside the bent portion 14 of the fixed tube 11, and the flexible tube 15 is substantially complete. It can be used in the same form as that of the first embodiment except that the insertion stopper 17 is stop-engaged with the distal end surface portion of the fixed tube 11 in the stored state (shown by an imaginary line).

In addition to the suction tube of the present invention, the flexible tube is formed of flexible hoses which do not have elasticity, and the pull-out stopper 12 at the tip of the fixed tube 11 in the first embodiment is used.
The inwardly facing flange (ring) -like member that is attached to the chamber wall 20 around the tip and projects to the internal corresponding portion of the fixed tube 11 on the extension line of the fixed tube 11 is used. Insertion stopper 1 for fixed tube 11 in
3 and / or the insertion stopper 17 of the flexible tube 15 may be omitted, or the insertion stopper 17 may be replaced by the flexible tube 1
5 is provided at the base end of the nozzle tube 18 adjacent to the tip of 5,
In addition, the insertion stopper 13 may be formed into a plurality of inward plate pieces or a series of flanges, or the insertion stopper 17 may be formed into a plurality of square pieces, plate pieces, or other non-flange shapes. However, the configuration is not limited to the illustrated example.
