Description

[Detailed Description of the Invention] The present invention relates to a hose band used for securing a hose or the like to a mouthpiece or the like.

Conventionally, in this type of hose band, a band-shaped elastic plate material is wound into a cylindrical shape so that one end intertwines with a notch provided in the longitudinal direction of the other end, and both ends are bent toward the outside of the cylinder. A device with a knob fixed part and a knob provided opposite to this fixed part is used.

This hose band expands the inner diameter of the cylinder by pressing these opposing knobs closer together with your fingertips, and when you release them at the position where they should be secured, the restoring force of the band will secure the hose to the mouthpiece. It is something.

When fixing the knob fixing part, this hose band has at least a surplus of at least the width of the elastic plate or the width of the knob fixing part. The size of the knob with meat on both sides was required, which resulted in the disadvantage that a large amount of material was used for the knob itself, the knob was easy to remove, and the workability of attaching the knob was poor.

The present invention has been devised in view of the above-mentioned circumstances, and aims to provide a hose band that eliminates the above-mentioned drawbacks of the conventional hose bands.

The present invention provides a hose band in which a band-shaped elastic plate material is wound into a cylindrical shape so that both ends intertwine with each other, and both ends are bent to the outside of the cylinder to form opposing knob fixing parts. A hose band comprising an insertion groove that gradually narrows toward the back from a knob opening into which a fixing part is inserted, and a protrusion parallel to the insertion direction in the insertion direction. It is.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

In Figures 1 to 4, 1 is the main body of the hose band wound into a cylindrical shape, 2 and 2' are a pair of knob fixing parts on the grooved side, and 3 is the knob fixing part on the other side. .

Figures 5 to 7 show a knob 4 inserted into the knob fixing parts 2, 2', with a groove 5 opening on one side wall, and a wall 6 extending halfway into the groove 5 to form a pair of narrow grooves. A groove 7.7' is formed.

Each of the narrow grooves 7, 7' is provided with a protrusion 8°8' parallel to the center shaft of each narrow groove, and the outer walls 9, 9' of the narrow grooves 7, 7' are provided with openings. It is inclined inwardly at a predetermined angle, for example, at an angle of about 4°.

Note that the protrusions 8 and 8' have inclined walls 10 and 10' near the opening.
is provided so that the protrusions 8, 8' gradually disappear.

Further, the walls 11, 11' are also gradually inclined toward the back from the opening so that the grooves 7, 7' become gradually narrower.

Figures 8 to 10 show another knob 14 inserted into the knob fixing part 3, with a groove 15 opening on one side wall and a protrusion 1.
8 is placed parallel to the center of the hole.

The walls 19 on both sides of the groove 15 are inclined inwardly at a predetermined angle toward the back of the opening, for example, at an angle of about 2° on one side.

Note that the protrusion 18 is provided with a sloped wall 20 near the opening so that the sloped wall 20 gradually disappears.

Further, the wall 21 is also gradually inclined toward the back from the opening, so that the groove becomes gradually narrower.

Note that each of the protrusions 8, 8' and 18 has an arcuate cross section, but is not limited to such a shape as long as the function described below can be achieved.

Alternatively, the knob fixing parts 2 and 2' may be formed in advance so that the distance between them is opened outward.

First, the pair of knob fixing parts 2, 2 of the hose band main body 1
′ into the opening of the knob 4, the knob fixing part 2,
2' is pushed into the center of the knob by the walls 9, 9' of the narrow grooves 7, 7' of the knob 4, and is inserted so as to be bent. Each of the knob fixing parts 2, 2' deforms while being subjected to a curving action, centering on the ridgeline of the top of the knob fixing parts 2, 2', and the knob fixing parts 2, 2' are deformed while being subjected to a curving action. ′ is squeezed.

The inclined walls 10 and 10' of the protrusions 8 and 8' are the knob fixing parts 2,
2' facilitates entry.

When the knob 14 is inserted into the opening of the knob fixing part in exactly the same way, the knob fixing part 3 is pressed to the center by the inclined walls 19 on both sides, and at the same time, the protrusion 18 in the center presses the knob fixing part 3 to the center.
It is deformed by the bending action and fixed in the groove 15 of the knob 14.

As described above, according to the hose band of the present invention, the knob fixing parts 2, 2', and 3 are pressed to the center and are simultaneously deformed by the bending action, and the knobs 4, 14 are held by the resulting spring action. Strongly fixed against the groove.

Therefore, the knobs 4, 14 are difficult to remove, and since the knob fixing parts 2, 2', and 3 are deformed and inserted closer to the center, the external dimensions of these fixing parts become smaller, and the knobs are held by that dimension. Since the external dimensions can be reduced, the amount of material required for molding the knob itself can be reduced.

In addition, the operation of inserting the knob does not require any special skill, and the protrusions 8, 8' and 18 and the inclined walls 10 and 10 arranged in the groove can be inserted easily.
' and 20 facilitate insertion and deformation, improving workability.
