Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a floor nozzle for a vacuum cleaner that is provided with a bumper on the outer periphery.

BACKGROUND ART Conventionally, this type of floor nozzle for a vacuum cleaner has generally had a structure as shown in Japanese Patent Publication No. 48-25347, and has a structure as shown in FIGS. 6 and 7. There is. In FIGS. 6 and 7, a bumper 1 made of a soft elastic material and having a U-shaped cross-section is fitted into a protruding rib 2a having a substantially L-shaped cross-section and integrally provided on the peripheral wall of the outer body 2. Holes 1 are installed and provided on the upper surface of both ends of the bumper 1.
The bumper 1 is prevented from coming off by being inserted and locked into a pin (not shown) provided to project upward from the main body projection rib 2a.

Problems that the invention aims to solve However, with the conventional structure like this, both ends of the bumper 1 are securely fixed, but an upward force is applied to the bumper 1 near the center of the bumper 1. This has the problem that it easily comes off from the protruding rib 2a. Further, the holes 1a at both ends of the bumper 1 must be processed after extrusion molding, which increases the number of man-hours.

In addition to the above-mentioned conventional example, examples of measures to prevent the bumper from coming off include using a molded product that can freely provide projections etc. for fixing the bumper to the main body, instead of extrusion molding the bumper, There are some types in which the bumper is attached to the main body by adhesive, and others in which the bumper is sandwiched between upper and lower parts, but these have not sufficiently solved the problems of cost and ease of assembly.

The present invention solves these conventional problems, and aims to provide a nozzle for a vacuum cleaner that has a bumper mounting configuration that can be installed reliably, does not easily come off, and is easy to install. It is.

Means for Solving the Problems In order to solve the above problems, the present invention has a cross-sectional shape that is formed integrally with the outer peripheral wall of the main body and has an outward claw portion at the tip. A generally L-shaped upward protruding rib is provided, the rib is made of a soft elastic material, the cross-sectional shape is approximately U-shaped so that the protruding rib can be fitted into the protruding rib, and a recess that engages with the claw at the tip of the protruding rib is provided at the inner wall deep part. At the same time, a bumper having a lip that comes into pressure contact with the outer shell of the main body is provided on the outer side of the main body at the upper end, and a gap closed by the lip is formed between the inside of the bumper and the outer peripheral surface of the outer shell of the main body. It is something.

Effect With the above configuration, the inner wall of the bumper, which has a substantially U-shaped cross-sectional shape, is locked with the claws provided on the protruding ribs, so it can be prevented from coming off even if the bumper is pushed upward, and moreover, the bumper can be flipped over. Even if you try to remove it, the amount of displacement of the portion of the bumper that corresponds to the claw part is small, and the upper end of the bumper has a lip that presses into contact with the outside of the main body, so this lip prevents it from turning up. , it does not come off easily and can be reliably prevented from coming off. In addition, when installing the bumper, it is sufficient to simply push the protruding rib into the bumper from above, which improves assembly work efficiency.Furthermore, the lip closes the gap between the bumper and the outer shell of the main body. Since it prevents dust from entering, it is effective in terms of improving marketability and hygiene. Moreover, the bumper can be constructed from an extrusion molded product and can be obtained at low cost.

Embodiment Hereinafter, an embodiment of the present invention will be described based on the drawings.

In FIGS. 1 to 5, 10 is outside the main body,
10a is a protruding rib having a substantially L-shaped cross section and integrally formed on the outer circumferential wall of the floor nozzle main body 10;
10b is a plurality of claws formed intermittently at the tip of the protruding rib 10a; 11 is a bumper made of an extruded product made of a soft elastic material; 11a is the claw 10b provided on the bumper 11; A recessed portion 11b that engages with the bumper 11 is provided at the upper end of the bumper 11 on the side facing outside the main body.
This is a lip formed to be pressed against zero.

The operation of the above configuration will be explained. When attaching the bumper 11 to the protruding rib 10a, the bumper 11 may be pushed in from above. Claw portion 10b
Since the bumper 11 is inclined and the claw portions 10b are provided intermittently, the bumper 11 can be easily inserted. When a force is applied to the attached bumper 11 from below, it will not easily come off because the recess 11a is fitted into the claw 10b. Furthermore, as shown in FIG. 5, even when the bumper 11 is turned over and removed, the recess 11a
Since the lip 11b is located deep inside the inner wall of the lip 11, the amount of displacement is small, and the lip 11b acts as a resistance against turning up, so it does not come off easily.

In addition, since the lip 11b is in pressure contact with the outer shell 10 of the main body, it prevents a gap from forming between the bumper 11 and the outer shell 10 of the main body, which improves marketability and prevents dust from entering. There is.

Effects of the Invention As described above, according to the present invention, it is possible to improve assembly work efficiency, reliably prevent the bumper from coming off, and further improve marketability and hygiene. Furthermore, since the bumper can be constructed from an extrusion molded product, it can be manufactured at low cost. Furthermore, since the protruding ribs are upwardly shaped in a substantially L-shape, the bumper's function can be enhanced by utilizing its own elasticity.
