[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a broom that can be cleaned while dust is scattered.
[0002]
[Prior art]
As a conventional broom, there is a broom in which a hair bundle made of a chemical fiber such as nylon is bundled in a horizontally long plate shape, the base end portion of the hair bundle is fixed at the concentrating portion, and the concentrating portion and the tip of the gripper are connected. is there. And when cleaning with a conventional broom, grasp the gripper with your hand, push the tip of the hair bundle made of chemical fibers against the ground, and restore the original state with the elastic force of the hair bundle By returning, dust and dust can be swept out, and dust and dust can be collected and cleaned.
[0003]
[Problems to be solved by the invention]
However, in the case of a conventional broom, since a hair bundle using a chemical fiber such as nylon is densely focused, the hair bundle is pressed by pressing the tip of the hair bundle against the ground. When the dust and dust are swept out and collected with the elastic force, the dust is excessively scattered.
[0004]
Therefore, the present invention is intended to provide a broom that can be smoothly cleaned by suppressing the scattering of dust and dirt.
[0005]
[Means for Solving the Problems]
As a result of diligent research to solve the above-mentioned problems, the present inventor fixed the proximal end portion of the hair bundle in which the flocks made of chemical fibers are bundled together at the gathering portion, and connected the gathering portion and the distal end portion of the gripper. A broom that is located on the outside of the hair bundle is expanded toward the outside, so that the hair transplant part of the hair bundle is composed of a central flocked part and an expanded flocked part, The present invention is provided by developing a broom characterized by forming a gap separating both flocked portions between the expanded flocked portions .
[0006]
Further, a broom in which the proximal end of a hair bundle in which flocks made of chemical fibers are bundled in a horizontally long plate shape is fixed at the gathering portion, and the gathering portion and the distal end of the gripper are connected to each other, the long side of the hair bundle The hair transplantation part located on the outside is expanded toward the outside, so that the hair transplantation part of the hair bundle is composed of the central hair transplantation part and the widening hair transplantation part, and both the flocking between the central hair transplantation part and the widening hair transplantation part Another object of the present invention is to provide a broom characterized by forming a gap for dividing the part .
[0007]
Furthermore, it is preferable to set the spread angle of the flocking of the spread flocking portion irregularly.
[0008]
In addition, it is preferable to form 3 to 5 rows of planted portions located on both sides of the hair bundle in which the planted hairs are bundled in a horizontally long plate shape to form the expanded planted portion.
[0009]
The hair bundle manufacturing method according to the present invention is a method for manufacturing a hair bundle in the broom, wherein a base end portion of a hair bundle in which flocks made of chemical fibers are bundled is positioned in a mold, and insert molding is performed with a synthetic resin. In the case where the concentrating part is formed by the above, the flocked part located outside the hair bundle by applying a press to the root part of the spread flocked part located on both outer sides of the hair bundle by the clamping pressure in the mold Is expanded outward.

DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments embodying the broom of the present invention will be described below with reference to the accompanying drawings.
1 to 4 show a broom of a typical embodiment.
As shown in FIGS. 1 to 4, the broom A arranges the flocks 1 in the horizontal direction so as to have a predetermined width, and the base end portion of the bristles 2 arranged in a horizontally long plate shape is arranged in a plate-like manner. It is fixed at the part 3, and the gathering part 3 and the tip of the gripping rod 4 are pivotally connected to each other so as to be rotatable. Especially in the example shown in the figure, chemical fibers such as nylon, polypropylene, vinyl chloride, polyester, etc. The base end of a bundle of hairs 2 that has been bundled with a number of flocks 1 of approximately the same length made of a material and positioned in a mold and fixed by a concentrating part 3 that is integrally molded with a synthetic resin It is. The flocking 1 can be linear or wave-shaped.
[0011]
And the hair bundle 2 is expanded with the center flocking part 2a using the flocking 1 of the same length by expanding the flocking part located in the both outer sides of a long side toward the outside from the root. It is comprised by the expanded hair transplant part 2b, 2b. In order to obtain an effect to be described later, the spread hair transplant part 2b sets the length of the hair transplant 1 unevenly. However, it is also possible to set the length of the flock 1 to the same length.
In the illustrated hair bundle 2, the length of the hair bundle 1 is set to about 5.5 cm, the thickness of the hair bundle 2 is set to about 0.5 cm, and the width is set to about 31 cm. The proximal end of the flocked portion is expanded so that the outer flocked portion in the 3 to 5 rows is positioned between about 3 to 7 mm from the end surface of the central flocked portion 2a so that the front end of the flocked irregularly opens outward. Open. That is, the angle at which the flock 1 is expanded is not a constant angle, but is expanded at an irregular angle. In the broom A in the illustrated example, the broom A is bent and expanded from the root, but it may be bent and expanded in the middle of the flock 1.
[0012]
Furthermore, in order to expand the flocked portions on both outer sides of the hair bundle 2 to form the central flocked portion 2a and the expanded flocked portion 2b, a thin plate is inserted on both sides of the follicle bundle 2, and then it is tilted outward. Thereby, the flocked part located in both the outer sides can be bent outward. Furthermore, it can be expanded outside by applying hot water to the root part of the flocked part located on both outer sides of the hair bundle 2 and causing thermal deformation. Further, when the base end portion of the hair bundle 2 is positioned in the mold and insert molding is performed with a synthetic resin, the root portion of the spread hair portion 2b located on both outer sides of the hair bundle 2 is placed in the mold. With the mold clamping pressure, the flock can be opened outwards by pressing.
[0013]
In the above-described broom A, the outer flocked portions in the third to fifth rows located on both outer sides of the long side of the hair bundle 2 are expanded outward to form the expanded flocked portion 2b. Only the hair transplantation part of the outer side of a row | line | column, or what expanded the hair transplantation part of six or more rows may be used.
Furthermore, the material for flocking the hair bundle 2 is not limited to chemical fibers, and it is also possible to use plant fibers, animal fibers, metal wires, and the like. It is also possible to manufacture with a metal such as stainless steel.
[0014]
Further, in the illustrated broom A, the expanded hairs 2b are provided on both outer sides of the hair bundle 2, but the expanded hairs 2b are provided only on the side corresponding to the surface for sweeping dust and dirt. Or all the flocked parts outside including the surface of both short sides may be expanded outward.
[0015]
Further, the broom A in the figure uses a hair bundle 2 having a rectangular shape in a front view, but is not particularly limited, and may be a hair bundle 2 having a substantially square shape. Although not particularly illustrated, the outer hair transplantation part may be expanded outward using a substantially cylindrical hair bundle 2 or a polygonal column hair bundle 2 such as a substantially quadrangular prism.
[0016]
When cleaning with the broom A of the present embodiment, as shown in FIG. 5 (a), if the grip 2 is held by hand and the tip of the hair bundle 2 is pressed against the ground, the hair bundle 2 is inclined. Then, before the central flocking portion 2a springs, the expanded flocking portion 2b having a weak elastic force is gently splashed outward while the dust and dust are scattered, as shown in FIG. 5 (b). If dust or dust is held between the flocked part 2a and the expanded flocked part 2b, and the hair bundle 2 is slanted, the center flocked part 2a and the expanded flocked part 2b are closed so that the center The flocked portion 2a splashes outward, sweeps out dust and dirt on the ground, and collects dust and dust for cleaning. Therefore, according to the broom A of the present embodiment, when the front end portion of the hair bundle 2 is pressed against the ground and the hair bundle 2 is slanted, the expanded flocking having a weak elasticity before the central flocking portion 2a. When the portion 2b splashes outward, and dust and dust are further carried between the central flocked portion 2a and the expanded flocked portion 2b, and the hair bundle 2 is slanted further, the central flocked portion 2a and the expanded flocked portion 2b The center flocking part 2a splashes outward, scrapes out dirt and dust on the ground, and collects dirt and dust, so that the dust and dust are not scattered violently. Can be cleaned smoothly. In particular, in the above-described broom A, since the spread angle of the flocked hair 1 in the spread flocked portions 2b and 2b is set irregularly, the elastic force is dispersed even if the spread flocked hair portion 2b splashes outward. It is difficult for dust and dust to be scattered.
[0017]
【The invention's effect】
As is clear from the above description, the following operations and effects are achieved.
According to the broom according to claim 1 and the broom according to claim 2, when the gripper is gripped by hand and the tip of the hair bundle is pressed against the ground to make the hair bundle slant, before the central flocking springs, Spreading hairs with weak elastic force splash outside slowly without scattering dust and dust, hold dust and dust between the central hairs and spreading hairs, and make the hair bundle slant. Then, between the central flocked portion and the expanded flocked portion is closed, the central flocked portion splashes outward, sweeps out dust and dirt on the ground, and collects dust and dust for cleaning. Therefore, cleaning can be performed smoothly without violently scattering dust and dirt. In particular, according to the broom according to claim 2, since the entire horizontally long hair bundle has a strong elastic force, the elastic force can be weakened by providing the expanded hair transplant part, which is more effective.
[0018]
According to the broom of claim 3, since the spread angle of the flocked hair in the spread flocked portion is set irregularly, even if the spread flocked portion splashes outside, the elastic force is dispersed and the dust It is difficult to scatter dust.
[0019]
According to the broom according to claim 4 and the broom according to claim 5, 3 to 5 rows of planted portions located on both sides of the hair bundle in which the planted hair is bundled in a horizontally long plate shape are expanded to form an expanded planted portion. If this is the case, it will be possible to minimize the area of the expanded flocked part, and it will have an excellent effect of scattering dust and dust. It is strong and the scattering of dust and dirt becomes a problem, so that the expanded hair transplantation part is more effective.
