Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a brush for cleaning the bodies of adults and infants, and particularly relates to a "bundle" shaped brush.

(Prior art) Conventionally, this type of "bundle" type brush has a brush member made of natural fibers such as palm or synthetic resin fibers such as nylon wrapped around the outer periphery of a substantially cylindrical core member.
The brush member is formed by being tightened and fixed to the core member by tightening a tightening member such as a wire wound around the outer periphery.

(Problem to be solved by the invention) In the brush formed as described above, the brush member disposed on the outer periphery of the core member is held only by the tightening force of the tightening member, so the core member is There was a problem that it easily fell off and productivity was poor.

Further, when the brush is used, the core member tends to come off and the brush member comes apart easily, and its durability is also poor.

This invention was proposed in view of the above problems.
The purpose is to reliably prevent the core member from coming off.

(Means for Solving the Problems) In order to achieve the above object, the present invention consists of a core member, a brush member wound around the core member, and a tightening member that tightens the outer periphery of the brush member in the direction of the core member. The core member is formed into a cylindrical shape, and a plurality of protrusions for retaining the shape of the brush member are formed radially outwardly at appropriate intervals on both upper and lower ends of the core member.

(Function) When the outer periphery of the brush member wrapped around the core member is tightened with a tightening member, the protrusion for retaining the shape of the brush member bites into the brush member, preventing relative movement between the brush member and the core member, and tightening the core member. This reliably prevents the member from coming off and the brush member from coming off.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

[Example 1] Reference numeral 1 in FIG. 1 indicates a brush as a whole, and as shown in FIGS. 2 and 3, this brush 1 has a core member 2 formed in a short cylindrical shape made of synthetic resin, and a core. Part 2
The brush member 3 is wound around the outer circumference of the brush member 3 in multiple layers, and the tightening member 4 is tightened at an intermediate height position on the outer circumference of the brush member 3.

The core member 2 has a plurality of wedge-shaped brush member shape-retaining protrusions 5 radially protruding outward from the upper and lower peripheral edges of the cylinder at appropriate intervals.

The brush member 3 is formed into a band shape by folding a synthetic resin filament 6 several times to the same size L and aligning the same, and then sewing the center portion of the filament 6 with a sewing machine 7.

Further, the tightening member 4 includes a nylon band 8
It is formed of.

In addition, the reference numeral 9 in the figure is a loop for suspending the brush 1 from a hanging fixture (not shown).

Each member 2, 3, 4 formed as described above is formed by wrapping the brush member 3 around the outer periphery of the core member 2.
When the outer periphery of the central portion of the brush member 3 is tightened with the tightening member 4, a "bundle" shaped brush 1 is manufactured.

In this way, in the brush 1 manufactured in the "bundle" shape, the protrusion 5 for retaining the shape of the brush member is attached to the brush member 3 by the tightening force of the tightening member 4, as shown in FIG.
It retains its shape and bites deeply into the brush member 3 to prevent relative movement between the core member 2 and the brush member 3, ensuring that the core member 2 and the brush member 3 do not come off or come off when the brush 1 is manufactured or used. It is prevented.

[Embodiment 2] In this embodiment, as shown in FIG.
It is made of 10 fibers of gourd,
The case where the brush member 3 is formed from the fibers 10 of gourd will be explained next.

First, the fibers of the gourd are separated from the pulp, dried, and then bleached to form what is called a natural loofah.

Next, cut the central part of the "loofah" into a plate shape, cut it into strips with a constant width, and then provide slits 11 running in the width direction on both peripheral edges at appropriate intervals in the length direction. Thus, member 3 is formed.

When the brush member 3 is formed in this manner, there is an advantage that even a distorted shaped gourd can be used without difficulty.

In each of the above embodiments, the brush member 3 is made of a single material such as synthetic resin fibers or natural fibers such as gourd, but it may be made of a composite material that is a mixture of both materials. Of course, it is also possible to add a synthetic resin sponge or the like to the brush member 3.

Further, the material of the core member 2 can be made of synthetic resin, wood, or metal.

Furthermore, the tightening member 4 may be replaced with a nylon band and may also be a wire or string.

(Effect of the invention) As described above, according to the invention, the protrusion for retaining the shape of the brush member bites into the brush member and prevents the core member from coming off. This has the advantage that the brush member is prevented from slipping out or coming off, greatly increasing productivity and significantly increasing the service life.
