Abstract

PROBLEM TO BE SOLVED: To provide a wiper which looks fine, whose wiping fringes are highly durable, and which can catch fine dust as well as large dust. SOLUTION: This wiper has an outer fringe 21 made of stranded thick threads which is planted outside on the underside surface of a base 11 made of nylon canvas, and an inner fringe 22 which is planted inside on the underside surface of the base 11. The inner fringe 22 is made of stranded threads which are heated after stranding nylon adhesive threads over base stranded fine threads. The length of the inner fringe 22 is such that it doesn't come out of the outer rim of the base 11 when the wiper is used. As the wiper is a mop with such fringes mentioned above, the inner fringe 22 is always hidden inside the lower surface of the base 11 with only the outer thick-thread fringe 22 coming out, so the device looks fine. Since the base stranded threads of the inner fringe 22 are fused with nylon adhesive threads, the threads of the inner fringe 22 are hardly loosened and the durability of the wiping fringes is improved.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiping tool used for, for example, floor cleaning.

[0002]

2. Description of the Related Art Conventionally, a mop 50 as shown in FIG. 5 has been often used as a wiping tool for wiping and cleaning floors of homes and stores. This mop 50 has a handle 51
An elliptical metallic support member 52 is rotatably provided at the tip of the mop member 53, and a mop body 53 is detachably attached to the support member 52.

The mop body 53 is composed of a base 54 made of an elliptical canvas, and a number of wiping chambers 55 made of twisted threads sewn on the entire lower surface of the base 54. There are two types of such mop bodies 53 for home use and business use. In general, a double thread obtained by twisting two single thick yarns is used for a wiping chamber of a household mop body in order to emphasize appearance, and a fine wiping chamber of a commercial mop body is used. Twisted fine yarn is used to emphasize the function of removing dust.

[0004]

In the case of a household mop body in which the wiping bunches are composed of twin yarns twisted by using two thick yarns such as the first yarn, each twin yarn is so thick that it is difficult to tear. Also, since each of the twin yarns has elasticity, it has an advantage that it is hard to be entangled with other adjacent twin yarns, that is, has a good appearance. However,
There is a problem that the size of dust and dust that can be captured by each twin yarn is limited.

[0005] On the other hand, when the wiping chamber is composed of nine to thirteen single yarns, such as a thin tenth yarn, like a commercial mop body, each of the twisted yarns is smaller than a domestic mop body.・ Even dust can be caught. However, since the twist of the twisted yarn is easily returned, the twisted yarn is easily unraveled, and when the twisted yarn is loosened into a single yarn, there is a problem in the durability of the wiping chamber such that the single yarn easily comes off or breaks.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and its object is to provide a good appearance, excellent durability of the wiping chamber, and to catch both large and small dust. It is to provide a mop body that can be used.

[0007]

In order to achieve the above object, according to the first aspect of the present invention, there is provided a wiping device comprising a plurality of wiping chambers made of twisted yarns provided on a lower surface of a fixing member. The gist of the present invention is that an outer tuft made of a thick yarn is arranged on the lower surface outside part of the fixing member, and an inner tuft made of a thin yarn is arranged on the lower surface inside part of the fixing member. Therefore, according to the first aspect of the present invention, the outer chamber captures large dust and dust, and the inner chamber captures small dust and dust.

In the invention according to claim 2 of the present invention, in the invention according to claim 1, the inner tuft comprises a plurality of under-twisted yarns formed by twisting a plurality of fine yarns around a thermoplastic core yarn. The gist is to be twisted below.
Therefore, in the invention of claim 2 of the present application, in addition to the effect of the invention of claim 1, the two ply-twisted yarns are fused to the thermoplastic core yarn, so that they are not easily separated.

According to a third aspect of the present invention, in the second aspect of the present invention, the gist of the first aspect is that the number of times of upper twist is set to be larger than the number of times of lower twist.
Therefore, according to the invention of claim 3 of the present application, in addition to the effect of the invention of claim 2, since the lower twist yarn is frayed at the tip end due to weak twist, finer dust and dirt are removed at the frayed portion. It becomes possible to catch.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. As shown in FIG. 1, a mop body 10 as a wiping tool according to the present embodiment has a base 11 as a fixing member made of nylon canvas having a substantially elliptical shape, and a bag portion made of nylon canvas on its upper surface. 1
2 are provided. The bag portion 12 is for mounting a support member having a handle (not shown), and is formed on the upper surface of the base 11 so that the openings of both bag portions 12 face each other. On the lower surface of the base 11, a large number of wiping chambers 13 made of a twisted cotton thread are sewn to catch dust and dust when wiping and cleaning.

As shown in FIG. 2, an outer tuft 21 formed of a thick twisted thread is sewn on the outer surface of the lower surface of the base 11, and the outer tuft 21 is formed on the lower surface of the base 11 inside the outer tuft 21. Is sewn with an inner tuft 22 formed of thin twisted yarn. That is, when the lower surface of the base 11 is viewed from below the base 11, the outer tuft 21 is annularly arranged near the outer periphery of the base 11, and the inner tuft 22 is arranged inside the outer tuft 21.

As shown in FIG. 3A, the twist yarn 32 for the outer tuft constituting the outer tuft 21 is a first twin yarn obtained by twisting two single yarns 31 of the first tuft. The number of twists is approximately 4 times / inch. Therefore, since one outer tuft yarn 32 is thick and resilient, it does not become entangled with the adjacent twin yarn.
2 remains extended.

The outer tuft 21 has one tuft sewn to the lower surface of the table 11 at an intermediate portion thereof. As shown in FIG. 2, one end 21a of the sewn tuft is The other end 21b extends toward the outside of the table 11 and
After temporarily extending toward the inside of the table 1, it is disposed so as to extend toward the outside of the table 11. In addition, the length of the tuft facing outward is longer than the length of the tuft facing inward. Therefore, when the mop is used, the inner tuft is positioned below the outer tuft.

As shown in FIG. 3 (b), the twisted yarn 36 for the inner tuft constituting the inner tuft 22 is formed by twisting at a rate of 1 to 2 times / inch using eight single yarns 33 of the 10th count and a primary twisting yarn. 34, and using the two lower-twisted yarns 34 around the nylon adhesive yarn 35 as a thermoplastic core yarn at a rate of 2 to 3 times / inch to obtain an upper-twisted yarn,
By performing heat treatment at about 130 ° C., the twist of the upper twist is prevented from returning. Therefore, the inner yarn 3
6 are fused by the nylon adhesive yarn 35 and are not frayed. However, since the lower twist yarn 34 is obtained by simply twisting the single yarn 33, the same single yarn 3
3 easily frayed at the end. That is, finer dust can be caught by the frayed portion than by the outer tuft 21. As shown in FIG. 2, the inner tuft 22 has one tuft at the center thereof and is sewn to the lower surface of the table 11. More specifically, as shown in FIG. 4, first, the twisted yarn 36 for the inner tuft is disposed in the substantially elliptical longitudinal direction of the base 11 on the inner side of the outer tuft 21 arranged on the lower surface of the stand 11.
Are arranged and held in a meandering manner, and the central portion 40 is sewn to the base 11 with a sewing machine or the like. And, the twist yarn 36 for the inner tuft
By cutting off the shells (a to f) remaining in an annular shape, the end of the twisted yarn for inner tuft 36 is put out. Note that the length of the twist yarn 36 for the inner tuft is such that it reaches the outer periphery of the table 11 at the longest. In use, the amount of thread in the outer tuft 21 and the inner tuft 22 are set so that the thickness of the outer tuft 21 and the inner tuft 22 pressed against the table 11 is substantially the same.
Is set. With the above-described configuration, when the mop is used, when the floor or the like is wiped, first, the outer tub 21 disposed on the lower surface outside portion of the base 11 catches large dust. In this state, if the wiping is continued, the inner chamber 22 disposed inside the lower surface of the table 11 catches the small dust that the outer chamber 21 misses. Also, during this wiping operation, the length of the outer tuft 21 is longer than the length of the inner tuft 22, so that the inner tuft 22 made of fine yarn that can be easily torn can be seen from above or sideways to the mop body 10. Not so good looking. In addition, the table 11
Since the outer tuft 21 and the inner tuft 22 on the lower surface have substantially the same thickness with respect to the floor surface, the portion of the wiping chamber 13 located on the lower surface of the table 11 uniformly contacts the floor surface. Not only can it be cleaned efficiently, but it can also catch large and small dust particles.

Therefore, according to this embodiment, the following effects can be obtained. (1) Since the wiping chamber 13 of the mop body 10 is composed of the outer chamber 21 made of a thick thread and the inner chamber 22 made of a fine thread, large and small dust and small dust can be wiped and cleaned.

(2) When wiping and cleaning, the outer chamber 2
Since the small dust / dust is captured by the inner chamber 22 after the large dust / dust 1 is captured, the inner chamber 22 is prevented from being clogged by the large dust / dust.

(3) Further, since the outer chamber 21 and the inner chamber 22 located on the lower surface of the table 11 have substantially the same height with respect to the floor surface during wiping cleaning, wiping and cleaning can be performed uniformly and efficiently. (4) Further, the inner tuft 22 formed of the fine thread is hidden by the outer tuft 21 during use and non-use, so that the appearance is good.

(5) Since the yarn forming the outer tuft 21 is the thick first yarn 32, it has elasticity and does not become entangled with other adjacent yarns, and maintains an extended state, so that it has a good appearance. .

(6) The yarn forming the inner tuft is a ply-twisted yarn 34 twisted at a rate of 1 to 2 times / inch using eight single yarns 33 of 10th count. Twisting the two twisted yarns 34 at a rate of 2 to 3 times / inch to form the upper twisted yarn 36, and at 120 to 130 ° C
By performing the heat treatment at a degree, the twist of the twisted yarn 36 is prevented from returning. Therefore, the two lower twisted yarns 34 constituting the upper twisted yarn 36 are not frayed because they are fused with the nylon adhesive yarn 35, but the lower twisted yarn 34 is
Since the single yarn 33 is simply twisted, the end of the single yarn 33 is easily frayed. In other words, the frayed portion is not only a portion for catching finer dust and dust, but also frayed only at the end, so that an effect that a single yarn is hard to be cut is obtained.

The present invention can be modified and embodied as follows. In the present embodiment, the canvas of the base 11 constituting the mop body 10 can be sewn so that the wiping chamber 13 can maintain its strength, if it can be sewn so as to maintain the strength. Natural fibers may be used.

In the present embodiment, the material of the wiping chamber 13 constituting the mop body 10 is embodied by natural fiber such as cotton. However, if the wiping property is ensured, for example, nylon or acrylic And chemical fibers such as rayon. Alternatively, it may be embodied by a blended yarn of nylon and rayon, acrylic and rayon, or the like.

Next, technical ideas other than the invention described in the claims, which can be understood from the embodiments and their modifications, will be described below together with their effects. (1) In a wiping tool provided with a large number of wiping chambers made of twisted yarn on a lower surface of a fixing member, an outer tuft made of a thick yarn is disposed on an outer surface of a lower surface of the fixing member. A wiping tool in which an inner tuft made of a twisted thin yarn is provided at an inner portion on a lower surface, the inner tuft having a length equal to or less than a length to a periphery of a fixing member.

Therefore, when the wiping device is used and not used, the inner tuft made of the fine thread is hidden by the outer tuft without being seen, so that the appearance is good. (2) The outer tuft has an intermediate portion fixed to the outer surface on the lower surface of the fixing member, and a portion of the outer tuft located outside the fixing member is located at a position inner than the fixing member. The wiping implement according to (1), which is long.

Therefore, the same effect as the above (1) is obtained.

[0025]

The present invention is configured as described above, and has the following effects. According to the first aspect of the present invention, since the outer tuft is made of a thick twisted yarn, the thick yarns do not become entangled with each other, and the appearance is good when the wiping tool is used or not used. Further, since the inner tuft is made of a thin twisted yarn, this wiping tool can wipe both large and small dust particles. Furthermore, since the inner tuft is located at the center of the fixing member, a force is easily applied at the time of wiping and cleaning, and dust can be removed well.

According to the second aspect of the present invention, the first aspect is provided.
In addition to the effect of the invention, the twist of the upper twisted yarn of the inner tuft is difficult to return, so that it does not fray. According to the third aspect of the present invention, in addition to the effect of the second aspect of the present invention, the twisted yarn is slightly twisted, so that the end of the yarn is easily formed into a single yarn, so that finer dust can be captured.
