Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a yarn bundle attaching holder for attaching a yarn bundle for cleaning to the tip of a handle bar of a mop.

[0002]

2. Description of the Related Art As a holder for attaching a yarn bundle of this type, a holder as shown in FIG. 6 is conventionally known. This holder 1
Is a synthetic resin and has a substantially inverted U-shaped cross section, and left and right halves 1a, 1a can be opened and closed by a hinge 2 formed at the top. As shown in FIG. 1
By holding the base end portion of the yarn bundle 3 between a and holding it by the clip type fitting 5 provided at the tip of the handle rod 4 of the mop, as shown in FIGS. To be attached to.

However, the above-mentioned conventional holder 1 has a drawback that the wet yarn bundle is difficult to dry and the stuffiness is apt to give off a bad odor because the ventilation of the inside and the outside of the holder 1 while holding the yarn bundle 3 is not smooth.

Further, since the left and right halves 1a, 1a can be freely opened and closed by the hinge 2, it is necessary to form a hook or the like for keeping them locked in a closed state, which complicates the structure. It is troublesome to integrally mold them, and the manufacturing cost is high.

[0005]

SUMMARY OF THE INVENTION An object of the present invention is to provide a yarn bundle mounting holder which has excellent breathability, has a simple structure, and can be easily molded.

[0006]

In order to solve the above problems, the holder of the present invention is a holder for attaching a cleaning yarn bundle to the tip of the handle bar of a mop, and is made of synthetic resin and has a substantially inverted U-shaped cross section. It is formed as an elongated non-opening and closing type channel member whose both ends are closed by, and its inner space is used as an insertion part for inserting the base end part of the yarn bundle, and on the inner surfaces of the left and right side walls, Plural pairs of locking claws that bite and lock are projected in a state of facing each other, and at the position corresponding to the above-mentioned locking claws on the curved top part, in the same holder width direction as the protruding height of the locking claws.
It has a length and is the same as the width of the locking claw in the holder axial direction.
It is characterized in that each of the ventilation holes has a hole .

[0007]

When the base end of the yarn bundle is press-fitted into the holder, the yarn bundle is elastically clamped by both side walls of the holder, and at the same time, the locking claws on the inner surface of the side wall bite into the yarn bundle to be locked. As a result, it is held very firmly in the holder.

The holder holding the yarn bundle is attached to the tip of the handle rod of the mop by a clip type attachment fitting or the like.

Even if the yarn bundle gets wet with water by using the mop, since the vent hole is formed at the top of the holder, the yarn bundle base end portion held in the holder is surely dried. You can do it, and there is no such thing as stuffiness and a bad smell.

Further, since the structure of the holder is simpler than that of the openable type, it is easy to integrally mold the synthetic resin, and the vent holes are formed at the positions corresponding to the respective locking claws. Therefore, the die-cutting hole for pulling out the die part for forming the locking claw can be used as it is as a vent hole, and it is not necessary to separately provide a hole.

[0011]

Embodiments of the present invention will now be described in detail with reference to the drawings. A holder 10 shown in FIGS. 1 to 4 is made of elastic hard or semi-hard synthetic resin and has a substantially inverted U-shaped cross section. Is formed as an elongated groove-shaped member whose both ends in the length direction are closed by end walls 11 and 11, and the internal space thereof is an insertion portion 12 for inserting a proximal end portion of a yarn bundle 15 (see FIG. 5).
The left and right side walls 13a, 13a of the holder 10 are
On the inner surface of b, a plurality of pairs of locking claws 14a and 14b, which bite into and lock the inserted yarn bundle 15, are provided at appropriate intervals in the length direction of the holder 10 so as to be opposed to each other. Has been done. These locking claws 14a and 14b are the insertion portion 1
It inclines toward the back of 2 and its tip is sharp.

On the curved top portion 10a of the holder 10, the locking claws 14 are provided at symmetrical positions with respect to the central axis.
Vent holes 17a and 17b corresponding to a and 14b are provided. These vent holes 17a and 17b are used for the holder 10
When viewed from the top portion 10a side, the position and the shape are formed so as to match the locking claws 14a and 14b, respectively. That is, in each of the ventilation holes 17a and 17b, the length (see FIG. 4) m in the holder width direction is the same as the height h from the inner surface of the side wall of the locking claws 14a and 14b, and the length n in the holder axial direction. (See FIG. 2) is formed to have the same width w as the locking claws 14a and 14b. These vents 17
a and 17b are locking claws 1 when the holder 10 is molded by the mold.
4a, 14b can be formed by using a die-cutting hole for extracting a die portion for forming 4a, 14b. By using the die-cutting hole in this manner, it is not necessary to separately provide the ventilation holes 17a, 17b.

Further, the holder 10 is provided with a mounting portion 20 for holding it by a clip-type mounting metal fitting 5 (see FIGS. 8 and 9) provided at the tip of the handle rod 4 of the mop. The mounting portion 20 is a recessed step portion that is slightly lower than the other portions, and the mounting bracket 5 is attached to the tip portion of the recessed step portion.
An engaging hole 21 for engaging the claws of is provided.

When the holder 10 having the above structure holds the cleaning yarn bundle 15, as shown in FIG.
The base end of 5 is pressed into the holder 10. As a result, the yarn bundle 15 is elastically sandwiched between the both side walls 13a, 13b of the holder 10 and at the same time, the locking claws 14a, 1 on the inner surface of the side wall.
4b bites into the yarn bundle 15 and locks it, so that it is held very firmly in the holder 10.

The holder 10 holding the yarn bundle 15 has the handle bar 4 as in the case of the conventional mop shown in FIGS.
It is attached to the handle rod 4 by sandwiching the attachment portion 20 with the clip-type attachment metal fitting 5 at the tip.

Although the yarn bundle 15 gets wet with water due to the use of the mop, a plurality of ventilation holes 17 are formed in the top portion 10a of the holder 10.
Since a and 17b are formed and the water evaporates through the vent holes 17a and 17b, the dry state of the yarn bundle base end portion held in the holder 10 becomes very good when the mop is not used, and There is no such thing as giving off a foul odor.

[0017]

As described above, according to the present invention, since the vent hole is formed in the holder, the yarn bundle base end portion held in the holder can be surely dried through the vent hole.
It is possible to prevent the wet yarn bundle from getting stuffy and giving off a bad odor.

Further, the holder is integrally formed as an elongated non-opening / closing type channel member having both ends closed in a substantially U-shaped cross section,
Since it is configured to press and hold the yarn bundle inside,
This holder is indispensable for conventional openable holders
No locking means to keep the
No kicking necessary, this since the structure is simple, easy to integrally molded by synthetic resin, also, the vent hole, high density
Formed on the side of the holder that is in close contact with the thread bundle
Rather, it tends to form relatively large gaps inside.
Since it is formed on the top of a simple holder, it has good breathability.
Since the inside of the holder is easily kept dry and the vent hole is formed at the position corresponding to each locking claw in the same size as the locking claw, the locking claw can be formed at the time of molding the holder. Molding
It is possible to streamline the design type vent hole for withdrawing that type portion as it is can be used as a vent
In addition, even if it is a non-openable channel member,
Easily molded with a structure that has a locking claw protruding in the direction
There is an advantage that can be done.
