Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vacuum cleaner hose attachment, and more particularly to an attachment to the end of a hose connected to a vacuum cleaner for cleaning inaccessible areas.

Tools or fixtures for cleaning elongated, narrow and deep areas are well known in vacuum cleaners. The working ends of these tools are long and tapered so that they can be inserted into narrow and deep areas, such as those found between cushions and around the edges of chairs and sofas. The flat end of this tool is usually cut at an angle to allow it to pick up debris from carpets close to walls.

For this reason, it has been proposed to provide a tool equipped with a brush that can loosen the dirt so that it can more easily be picked up by the tool. For example, U.S. Patent No. 2.679.
This is the case with No. 068. This U.S. patented brush is superior in terms of releasing dirt and dust, but the mounting position and arrangement of the bristles is different from the conventional so-called tapered brush.
ce tool) requires removal of the brush to perform the task, prescribing the use of the device as a tapered tool.

Another attempt to provide a brushed tapered tool is shown in US Pat. No. 2,811,738.

This patent provides a circular brush that snaps onto a tapered tool to convert the tool into a radiator cleaning tool, and the patent provides for a circular brush that snaps onto a tapered tool to convert the tool into a radiator cleaning tool, and the patent provides for a circular brush that fits into a tapered tool to convert the tool into a radiator cleaning tool, and the patent provides for a circular brush to be released by twisting the cover plate when the device is used as a radiator brush tool. The tool has multiple orifices on one side.

U.S. Pat. No. 2,101,222 also discloses a vacuum cleaner hose attachment having an elongated flat shape for use in removing dirt and foreign matter from the underside of furniture.

The novel configuration of the present invention thus has several advantages over known tapered tool structures. The multi-purpose tool of the present application can be used in a known manner both as a tapered tool and as a tool for cleaning between fairly difficult to access surfaces, such as between blind panels. To change the tool from one use to another, it is only necessary to move the sliding panel, which forms part of the device, forward or backward.

When changing usage, there is no need to increase or decrease the number of brushes. Thus, the tool of the present invention is self-retaining and does not require separate parts.

In the case of cleaning operations such as blinds, pulling back the sliding panel widens the elongated opening. Air is drawn in through this elongated opening because the opening is larger than the end opening of the tool, and the beveled shape of the tool becomes flatter towards the end, reducing the effective cross-section of the duct.

Low-height strip-shaped brushes are arranged along both sides of the elongated opening and are provided to remove dust and the like from blind panels and the like. These brushes are particularly suitable for cleaning blinds, and these brushes are made of a mixture of nylon (and pig hair). It increases the cleaning area and makes cleaning operations more effective.When cleaning narrow and narrow spaces, it can be converted very quickly by simply sliding the panel.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a vacuum cleaner hose attachment tool which has superior advantages as a cleaning tool for cleaning narrow and deep areas and as an improved tool for cleaning between blind panels in one integrated device. It is to be.

Another object of the present invention is to provide an installation tool having characteristics that allow it to be quickly and instantaneously converted from a narrow and deep work tool to a blind cleaning tool without the need for installation or removal of parts.

A further object of the invention is to provide a mounting tool as described above which is simple and robust in construction and which also allows the strip brush to be easily replaced in case of wear.

Yet another object is to provide a multi-purpose mounting tool of the character described above that is effective in easily and effectively removing dust from the tops of books in bookshelves and similar confined spaces.

Further, in order to better understand other objects, characteristics, and advantages of the present invention, specific examples will now be described.

Examine the diagram in detail. The vacuum cleaner hose attachment tool of the present invention includes an elongated flat tubular housing 11. This housing 11i,j has an end 12 for connection to the hose 13 of the TG vacuum cleaner and an opposite end 14 providing a flat air intake opening 16. One flat surface 17 of the housing has an elongated opening 18 extending through the center of the core 17 in the vicinity of the end 14 . This opening 18 has this opening.
Means 19 are provided which are configured to selectively cover said opening 18 for introducing air into the interior 21 of the housing through it. Furthermore, a pair of elongated brushes 22, 23 are disposed on the flat surface 17 of the housing 11 and extend along opposite sides of the elongated opening 18.

As clearly shown in FIG.
4, the cross-sectional area of the interior 21 of the housing decreases as it approaches its end 14. As shown, the inclination of the housing 11 provides a flat surface 17 with an opening 18 formed therein. The means 19 for selectively covering the aperture 18 comprises a flat elongated rectangular panel which extends from end to end between a closed position in which the elongated aperture 18 is completely covered and an open position in which it is not covered. It is mounted on the housing 11 so as to be moved in sections. This sliding means 19 is shown in an intermediate partially open position in the figure.

As shown, the housing 11 is formed with receiving grooves 24,26 extending along the opposite longitudinal sides 27,28 of the opening 18, into which grooves 2.4, 26 the longitudinal side edges of the panel 19 can slide. It is placed on. The top surface of the panel 19 is formed with an upwardly extending tab 29 for fingering to facilitate sliding of the panel between open and closed positions.

Preferably, as shown, the housing 11 and the sliding panel 1
9 is molded from plastic, and the brush 22.23 is inserted into the opening 1 on the outside of the groove 24.26, as shown in FIG.
It rests in a groove 31.32 molded into the housing 11 along the opposite longitudinal sides 27.28 of the housing 11.

The brush extends slightly beyond the ends of the elongated opening 18 and is preferably curved so that the ends of the brush near the housing end 14 inwardly approach each other as shown in FIG.

The shape shown here can be used between closely spaced surfaces such as blind panels, between the top of a book and an upper shelf, behind an air purifier or cooler or between it and a side wall, or between a window shutter or a side wall. The cleaning action of this tool is extremely easy when cleaning one side of an armor window plate or between the glass pieces of window blinds. This multi-purpose tool of the present invention provides a great deal of versatility in cleaning areas and offers excellent applicability to a variety of cleaning methods. This tool has opening 18
