Description

[Detailed Description of the Invention] (Field of Application) The present invention relates to a structure for attaching a rubbing material to a scrubber with a handle, and can also be used in sponge scrubbers and non-woven scrubbers.

(Prior art and its problems) So-called handle scrubbers, which have a handle attached to the scrubber body, are used in various fields, and recently,
Many scrubbers are made of non-woven fabric or sponge scrubbers.

Since the Kamenoko scrubbing brush has a core wire, it is possible to connect the handle and the scrubbing brush body using this core wire. If a rubbing material made of non-woven fabric or sponge is used, it cannot be attached to the handle as it is because it does not have a core material as described above.

Therefore, as disclosed in Japanese Utility Model Publication No. 59-1650, in order to attach a nonwoven fabric, sponge, etc. to a handle, a core material provided separately from the handle was wrapped with a rubbing material such as the nonwoven fabric. A configuration is adopted in which a scrubber main body is formed and this scrubber main body is attached to a handle using the core material.

In this conventional type, the core material provides a certain amount of firmness, so the force acting on the handle is transmitted to the rubbing material through the core material, resulting in the same rubbing effect as the conventional turtle scrubbing brush. is obtained.

However, with this conventional type, attaching the rubbing material to the handle is troublesome.

As a solution to this inconvenience, the
There is one disclosed in No. 16961, in which
A concave groove is formed around the block-like scrubber body, and an annular retaining ring formed at the tip of the handle is fitted into this concave groove.

However, in this conventional device, since the scrubber main body is press-fitted into a retaining ring having a constant diameter, there is a disadvantage that the scrubber main body cannot be strongly held by the retaining ring. This is because if the degree of bite of the retaining ring into the scrubber body is made deep, it will be difficult to attach the body of the scrubber to the retaining ring, and conversely, if the degree of bite is made gentle, the retaining force of the retaining ring will not be sufficient. This is because it does not become a thing.

The present invention is to enable the scrubber main body to be strongly tightened in "a scrubber with a handle of the type in which the scrubber main body 1 is held by an annular holding ring 21 and a handle 2 is connected to this holding ring 21". The task is to

(Means) The technical means of the present invention taken to solve the above-mentioned problems is that the scrubbing brush body is made of an elastic material such as sponge and has a uniform body part that is made of an elastic material such as a sponge and has a curved surface that is convex on the outer periphery. At the same time, there is a groove 1 on the body.
1, and the handle 2 and the retaining ring 21 are integrally formed of an elastic material such as synthetic resin, and the cross section of the retaining ring 21 is set smaller than the depth of the groove 11, and the handle 2 The holding ring 21 is fitted into the concave groove 11 of the scrubber main body 1, and the body of the scrubber main body 1 is wound and tightened, and the other free end is attached to the holding ring 21.
or the tip of the handle 2, and the open edges of the groove 11 are brought into close contact with each other.

(effect) The above technical means works as follows.

The scrubber body 1 and handle 2 are integrated by a retaining ring 21 connected to the tip of the handle, but when attaching the scrubber body 1 to this retainer ring 21, the tip is in an open state in advance. The scrubbing brush main body 1 is inserted into the retaining ring 21 located at the retaining ring 21, and then the distal end of the retaining ring 21 is engaged with the proximal end thereof. As a result, the scrubbing brush main body 1 is connected to the handle 2 in a state where it is wound and tightened by the retaining ring 21.

Therefore, compared to a structure in which the scrubber main body 1 is simply press-fitted into the annular retaining ring 21, the retaining ring 21 is
The holding force of the scrubber main body 1 becomes stronger. That is, if the retaining ring 21 is press-fitted in advance under predetermined conditions in a partially open state, and then the tip of the retaining ring 21 is engaged, the retaining ring 21 will be further held in a wound and tightened state.

In particular, the retaining ring 21 is inserted into a groove 11 formed in the body of the scrubbing brush main body 1 and is wound and tightened. Since the body of the scrubber main body 1 is constructed of a curved surface that is convex toward the outer periphery, the central part of the scrubber main body is thereby contracted and both end edges are brought into close contact with the cross section of the groove 11. Therefore, the scrubbing brush body 1
The groove formed on the surface of the body is closed all around. Further, the retaining ring 21 is housed within the scrubber main body 1.

(Effects) Since the present invention has the above configuration, it has the following unique effects.

Since the scrubber main body 1 is held in a wound and tightened state by the retaining ring 21 of the handle 2, and since this retaining ring 21 is accommodated in the groove 11, the scrubber main body 1 is held by the retaining ring 21. The holding power becomes even stronger.

Further, since the retaining ring 21 serving as the holding portion of the scrubber main body 1 is accommodated in the groove of the scrubber main body 1, and the open end of the groove 11 is closed all around, the groove is closed. It is difficult for foreign matter to enter the groove during cleaning. Furthermore, there is no fear that the retaining ring 21 will contact or collide with the surface to be cleaned and damage the surface to be cleaned during cleaning.

Further, since the body of the scrubber main body 1 has a curved surface that is convex toward the outer periphery, wrinkles do not occur on the surface of the body of the scrubber main body when it is wound and tightened by the retaining ring.

(Example) Hereinafter, an example of the present invention will be described based on FIGS. 1 to 6.

The first embodiment shown in FIGS. 1 to 3 has a ring-shaped retaining ring 21 connected to the tip of the handle 2.
As shown in FIG. 2, the scrubber main body 1 is made by forming a sponge into a thick disk shape and providing a concave groove 11 around the center of the circumferential side of the sponge.

In this case, the diameter of the bottom 12 of the groove 11 is set larger than the inner diameter of the retaining ring 21,
As shown in FIG. 3, the scrubber main body 1 is forcibly inserted into this retaining ring 21. Further, the retaining ring 21 is formed in a partially open state, and the tip thereof is a hook-shaped engagement piece 22. In order to engage the engagement piece 22, a fixing ring 3 that is slidable in the axial direction is fitted onto the distal end of the handle 2, and the engagement piece 22 is attached to the proximal end of the retaining ring 21. When the ring 3 is moved to the tip side of the handle 2 in line with the
1 is attached. In this embodiment, the size of the inner periphery of the retaining ring 21 in the engaged state is set to be smaller than the size of the groove 11 of the scrubber main body 1.

Furthermore, in this embodiment, a large number of engaging protrusions 23, 23 are protruded from the inner periphery of the retaining ring 21. Therefore, when the scrubber main body 1 is housed in the retaining ring 21 and the tip of the retaining ring 21 is engaged, the engaging protrusions 23, 23 bite into the scrubber main body 1, and the retaining ring 21 holds the scrubber main body 1. The power will be further improved.

In addition, in this embodiment, when the retaining ring 21 is attached to the groove 11, the groove 11 is closed by the retaining ring.
As shown in Fig. 1, the concave groove 1 is tightened.
The open portion 1 is closed, making it difficult for foreign matter to enter the groove.

Note that the structure for securing the tip of the retaining ring 21 is as follows:
The configuration shown in FIG. 4 can also be adopted.

In the second embodiment, a cylindrical portion 24 is formed at the free end of the retaining ring 21, and this cylindrical portion is fitted into and engaged with a shaft portion 25 formed at the tip of the handle 2, as shown in the figure. The holding ring 21 of the handle 2 formed in the state is
When the cylinder part 24 is bent using its elasticity and closed to the state shown by the two-dot chain line in the figure, and the cylinder part 24 is fitted to the shaft part 25, the elastic force of the retaining ring 21 and the shaft part 25 and the cylinder part 24 are combined. By fitting these, they are attached in a manner that prevents them from coming off.

Next, in the third embodiment shown in FIG.
The groove 11 is formed in the hard nonwoven fabric layer 10a.

In this case, since the hard nonwoven fabric layer is held by the holding ring 21 even though the front and back surfaces, which are the outer layer surfaces, are soft, the holding force by the holding ring 21 is further improved.

In the above, the grooves 11 can be formed by bringing the peripheral side of the block-shaped scrubber main body 1 into contact with a rotating grindstone such as a grinder and rotating the scrubber main body 1 as a workpiece, as shown in FIG.
