Abstract

PROBLEM TO BE SOLVED: To provide a dust collecting filter for vacuum cleaner which is improved so as to be fitted to a vacuum cleaner by folding the left and right edge parts of a bag body along both the side edges of a supporting plate or outside that supporting plate and providing folds parallel with folding lines at the section of the bag body overlapped with flange parts. SOLUTION: The dust collecting filter is composed of a bag body 1 for which a filtering member is formed cylindrical, both the end sides are closed and an opening part is provided at the almost center, and a supporting plate 2 having a dust sucking port. The bag body 1 and the supporting plate 2 are adhered so that the opening part of the former can be matched with the dust sucking port of the latter. In that case, flange parts 2b and 2c not adhered with the bag body are provided along both the left and right side edges of the supporting plate 2. Besides, both the side edge parts of the bag body 1 are folded onto the back side of the supporting plate 2 along folding lines 4a and 4b. Further, the bag body 1 is provided with folds 5a and 5b parallel with the folding lines 4a and 4b at any suitable position in the section of the supporting plate 2 overlapped with both the flange parts 2b and 2c.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dust collecting filter for an electric vacuum cleaner, and more particularly to a dust collecting filter for an electric vacuum cleaner in which a support is easily attached to a support plate mounting portion of the electric vacuum cleaner.

[0002]

2. Description of the Related Art When a support plate, which is formed of a filter medium and has an opening at substantially the center of one surface of a bag whose both open ends are closed and has a dust inlet, is adhered to the periphery of the opening, Provide a brim part that is not adhered to the bag along the left right edge,
A dust collecting filter for a vacuum cleaner is conventionally widely used, in which the left and right end portions of the bag are folded along the both side edges of the support plate or outside the support plate in parallel with the both side edges to the back side of the support plate. The folding method is as follows: (a) Folded at an appropriate portion near the center of the bag in the collar of the support plate, (b) Folded along the left and right side edges of the support plate, (C) Some of these were folded outward from these side edges.

[0003]

However, except for the case of (a) above, in the cases of (b) and (c), the bag body of the filter medium and the support plate are exactly overlapped at the brim portion of the support plate. Therefore, it is difficult to insert the brim portion into the guide of the dust collecting filter support plate mounting portion of the electric vacuum cleaner, and sometimes the metal piece of the support plate is hung on a part of the bag to break the bag. The present invention has been made in view of such circumstances, and its problem is a type in which the left and right side end portions of a bag body formed of a filter material are folded along the left and right side edge edges of a support plate, or outside thereof. Another object of the present invention is to provide an improved dust collecting filter for an electric vacuum cleaner that can be easily attached to the electric vacuum cleaner.

[0004]

In order to solve the above-mentioned problems, a dust collecting filter for an electric vacuum cleaner according to the present invention has an opening provided at substantially the center of one surface of a bag body in which both open ends of a tubular filter medium are closed. In a dust collecting filter for an electric vacuum cleaner, in which a support plate having a dust suction port according to the opening is adhered to the periphery of the opening, the bag is adhered to the left and right side edges of the support plate. A collar portion is provided on the support plate, and right and left end portions of the bag body are folded outward of both side edges of the support plate and parallel to the both side edges on the back side of the support plate, and the collar portion of the bag body is folded. It is characterized in that a folding habit parallel to the folding line is provided in a portion overlapping with. Further, the present invention folds the left and right end portions of the bag body along the both side edges of the support plate in parallel to the both side edges to the back side of the support plate and at the portion overlapping the brim portion of the bag body. The feature is that a crease parallel to the fold line is provided.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION In the dust collecting filter for an electric vacuum cleaner of the present invention, the left and right end portions of the bag body are arranged along the both side edges of the support body or at the outside thereof in parallel with the both side edges of the support plate. Even if it is a type that is folded on the back side, since the fold parallel to the fold line is attached to the part of the bag body that overlaps with both the brim portions, the user can take out the dust collection filter from the package one by one. According to the folding habit, the filter causes the left and right end portions of the filter to be separated from the support plate, which makes it easier to mount the support plate on the dust collecting filter support plate mounting portion guide of the electric vacuum cleaner. The action is achieved.
