Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a round mop in which a yarn bundle for wiping is attached to the tip of a handle bar in a tuft shape.
[0002]
[Prior art]
Conventionally, as a mop for cleaning a floor, furniture, etc., a round mop in which a thread bundle for wiping is attached to the tip of a handle bar in a tuft shape is widely known.
[0003]
This type of round mop removes dirt by pressing the yarn bundle against the object to be cleaned such as the floor surface with the handle bar to move back and forth, but it presses the yarn bundle with the small diameter handle rod. Since the pressing area is small, and the yarn bundle is very soft and weak, the pressing force from the handle bar cannot be sufficiently transmitted to the entire yarn bundle, and the operability is not necessarily good.
For this reason, a round mop has also been proposed in which a hook-shaped support member that covers the proximal end of the yarn bundle is attached to the tip of the handle bar, and the yarn bundle is pressed against the object to be cleaned by this support member.
[0004]
However, even in the mop with the support member, since the size of the support member is smaller than that of the yarn bundle, it is difficult to press the entire yarn bundle with the support member sufficiently efficiently.
[0005]
Although the pressing area can be increased by increasing the diameter of the support member, the mop is difficult to squeeze if the support member is too large. That is, this type of round mop is usually a mop in which a cylindrical diaphragm cover 30 having a flat elliptical cross section is slidably attached to a handle bar 33 and immersed in water as shown in FIGS. The yarn bundle 31 is squeezed by applying strong pressure from the outside with the squeeze cover 30. However, if the support member 32 is enlarged, it becomes an obstacle and cannot be squeezed. For this reason, conventionally, it has not been considered to make the support member 32 larger.
[0006]
If the mop is squeezed by a method other than the diaphragm cover, it is possible to enlarge the support member, but in this case, the manufacture of the support member becomes troublesome and tends to increase the cost, Since different types of support members must be used for a mop that is squeezed by a diaphragm cover and a mop that is squeezed by another method, the number of parts increases, making manufacturing and management cumbersome.
Therefore, it is desired to increase the pressing area of the yarn bundle without increasing the diameter of the support member.
[0007]
[Problems to be solved by the invention]
The main technical problem of the present invention is that in a round mop provided with a tufted yarn bundle and a hook-like support member covering the proximal end of the yarn bundle at the tip of the handle bar, the support member itself is greatly enlarged. Instead, the indirect method of attaching an auxiliary member is to enable easy and efficient enlargement of the pressing area of the yarn bundle by the support member.
[0008]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, a round mop of the present invention is attached to a handle bar for gripping, a yarn bundle for wiping attached to the tip of the handle bar in a tuft shape, and the tip of the handle bar. is a support member having a bowl-shaped portion that extends so as to cover the proximal end of the fiber bundle at the tip, as a separate member with the support member in a flange shape which is inclined flared in diameter than the bowl-shaped portion And an auxiliary member that is formed and interposed between the hook-shaped portion and the base end portion of the yarn bundle, thereby expanding the pressing area of the yarn bundle by the hook-shaped portion .
[0009]
The round mop having the above configuration is for removing and removing dirt while pressing the yarn bundle against the object to be cleaned with a handle as in the conventional round mop. At this time, since the yarn bundle can be pressed against the object to be cleaned with a wide pressing area by pressing both the support member and the auxiliary member, the working efficiency is very good.
[0010]
In addition, since the diameter of the supporting member itself is indirectly increased by attaching a hook-shaped auxiliary member without directly increasing the diameter, simply selecting whether the auxiliary member is attached or not, Two types of mops having different pressing areas can be obtained by using one type of support member, which facilitates the manufacture and management of the parts and is very efficient.
[0011]
According to a specific configuration aspect of the present invention, the yarn bundle is formed into a tuft by bundling a large number of mop yarns in a columnar shape and folding it in half, and a yarn bundle holder for attaching the yarn bundle to a handle bar Is composed of a bendable / stretchable belt-like member having a threaded half-cylinder part at both ends, and is fitted to the tip end of the handle bar by the two half-cylinder parts on the base end side when folded in two. A cylindrical portion having a thread on the outer periphery thereof is formed, and a loop-shaped holding portion that holds the central portion of the columnar yarn bundle is formed on the distal end side, The support member includes a tightening portion that is screwed onto the outer periphery of the cylindrical portion of the yarn bundle holder and fastens and fixes the yarn bundle holder to the handle bar, and a hook-like portion that covers the proximal end portion of the yarn bundle. The holding member is a member different from the support member, and has a larger diameter than the bowl-shaped portion and is inclined forward. So that the cylindrical portion of the yarn bundle holder is not opened by being fitted to the holding portion of the yarn bundle holder so as to be interposed between the hook-like portion and the base end portion of the yarn bundle. It has the function to hold | maintain and the function to expand the press area of the yarn bundle by the said hook-shaped part.
[0012]
According to a preferred embodiment of the present invention, the locking projections are formed on the inner surfaces of the half tube portions at both ends of the yarn bundle holder, and the projections are fitted and locked on the side surfaces of the handle bar. That is, holes are formed. Then, it is desirable to fit the auxiliary member on the outer periphery of the yarn bundle holder so that the yarn bundle holder can be held in a state where the protrusion is fitted in the locking hole.
[0013]
Thus, after fitting the half tube portions at both ends of the yarn bundle holder holding the yarn bundle from both sides to the tip of the handle bar, the auxiliary member is fitted onto the yarn bundle holder, thereby By holding the holder so that the cylindrical portion does not open to the left and right, and screwing the support member to the cylindrical portion in this state, the assembly work can be easily performed.
The auxiliary member is preferably made of an elastic material.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
1 and 2 show an embodiment of a round mop according to the present invention. The round mop of this embodiment includes a handle rod 1 for gripping, and a thread bundle holder at the tip of the handle rod 1. 3, a wiping yarn bundle 2 attached through 3; a support member 4 attached to the tip of the handle 1 so as to cover the proximal end of the yarn bundle 2; and a yarn bundle 2 formed by the support member. And a hook-shaped auxiliary member 5 for enlarging the pressing area.
[0015]
The yarn bundle 2 is formed into a tuft by bundling a large number of mop yarns 2a in a columnar shape and folding them in half at the center. The yarn bundle 2 is attached to the tip of the handle 1 by the yarn bundle holder 3 as follows. It is attached. That is, as shown in FIG. 3, the yarn bundle holder 3 is formed of a synthetic resin belt-like member 11 having half cylindrical portions 11a and 11a each having a thread on the outer surface at both ends. The belt-like member 11 is bent into two as shown in the figure, and is fitted to the distal end of the handle 1 on the proximal end side of the yarn bundle holder 3 by the two half tube portions 11a and 11a. A cylindrical portion 12 having a cylindrical shape and having a thread 12a on the outer periphery is formed, and a loop-shaped holding portion 13 that holds the central portion of the columnar yarn bundle 2 is formed on the distal end side. It is a thing.
[0016]
A locking projection 15 is formed on the inner surface of each of the half cylinder portions 11a, 11a, and a locking hole in which the projection 15 is fitted and locked to the side surface of the handle bar 1 on the other side. 16 is formed. Then, the center portion of the yarn bundle 2 is held in the holding portion 13 of the yarn bundle holder 3 so that the cylindrical portion 12 is fitted to the tip of the handle 1 and each projection 15 is engaged with the locking hole 16. After the auxiliary member 5 is fitted on the outer periphery of the yarn bundle holder 3 in a state of being fitted into the threaded bundle holder 3, the support member 4 is screwed and tightened to the cylindrical portion 12, whereby each of these members is secured to the handle bar. 1 is attached to the tip.
[0017]
The support member 4 includes a cylindrical tightening portion 4a that is screwed onto the outer periphery of the cylindrical portion 12 of the yarn bundle holder 3 to fasten and fix the yarn bundle holder 3 to the handle 1 and the tightening portion. 4a, which is formed at the tip of 4a so as to cover the base end of the yarn bundle 2, and has a flared hook-like portion 4b. The outer surface of the tightening portion 4a is spaced at regular intervals in the circumferential direction. A plurality of ribs 4c serving both for reinforcement and for preventing slippage during rotation are formed in the axial direction, and these are integrally formed of a hard or semi-rigid synthetic resin.
[0018]
On the other hand, the auxiliary member 5 is formed of a soft material such as rubber or synthetic resin, and has a base end portion 5a that fits in the hook-like portion 4b of the support member 4 and a front side of the hook-like portion 4b. It consists of a bowl-shaped tip portion 5b that extends in an annular shape on the outside, and this tip portion 5b is inclined so as to form a tip-open shape.
[0019]
The auxiliary member 5 is fitted on the yarn bundle holder 3 after fitting the half cylinder portions 11a and 11a at both ends of the yarn bundle holder 3 holding the yarn bundle 2 to the tip portion of the handle 1 from both sides. Thus, the auxiliary member 5 holds the cylindrical portion 12 of the yarn bundle holder 3 so that it does not open to the left and right, and in this state, by screwing the tightening portion 4a of the support member 4 to the cylindrical portion 12, The assembly work of each part can be performed easily.
[0020]
As shown in FIG. 4, the round mop having the above configuration is configured to wipe away and remove dirt while pressing the yarn bundle 2 against the object to be cleaned with the handle 1 via the support member 4 and the auxiliary member 5. At this time, since the yarn bundle 2 can be pressed against the object to be cleaned with a wide pressing area by pressing both the support member 4 and the auxiliary member 5, the work efficiency is very good. Further, since the auxiliary member 5 has a certain degree of elasticity, not only can the yarn bundle 2 be elastically pressed, but when the yarn bundle 2 is excessively pressed, the force is absorbed and relaxed by elastic deformation. Therefore, it is excellent in the feeling of use.
[0021]
Further, since the diameter of the supporting member 4 itself is not increased directly, but the diameter of the supporting member 4 is indirectly increased by attaching the hook-shaped auxiliary member 5, it is selected whether the auxiliary member 5 is attached or not attached. Only one type of support member 4 can be used to obtain two types of mops with different pressing areas, which facilitates the manufacture and management of the parts and is very efficient.
[0022]
When squeezing the mop, as illustrated in FIG. 5, a squeezing member 20 having a porous recess 21 is attached to a bucket handle or the like, and the mop yarn bundle 2 immersed in water is placed in the recess 21. Then, the handle 1 is rotated so that the yarn bundle 2 is twisted and pressed strongly against the recess 21. Thereby, the mop can be easily and efficiently squeezed by the support member 4 and the auxiliary member 5.
When the auxiliary member 5 is removed, a conventional mop that is squeezed with a squeeze cover as shown in FIGS. 6 and 7 can be obtained.
[0023]
【The invention's effect】
As described in detail above, according to the round mop of the present invention, the pressing area of the support member can be enlarged and the workability at the time of cleaning can be remarkably improved by a simple method of attaching the hook-shaped auxiliary member. it can.
Moreover, since the diameter of the supporting member itself is indirectly increased by attaching a bowl-shaped auxiliary member without directly increasing the diameter, simply selecting whether to attach the auxiliary member or not, Two types of mops having different pressing areas can be obtained by using one type of support member, which facilitates the manufacture and management of the parts and is very efficient.
