JP 2000-230376 A

Depending on the structure of the screen door, the pile foot may be lengthened, but in this case, the hair tip portion (tip portion) is likely to be scattered and spread, and the contact area with the shoji warp etc. becomes large. Therefore, the sliding resistance between the mohair and the shoji warp etc. increases, and it becomes difficult to open and close the shoji and screen door. Further, the design of the appearance of the tip portion is not good. In addition, if the pile has long hair, it tends to cause curl and it is difficult to attach it to the screen door during handling and assembly.
Accordingly, the main problem of the present invention is to provide a mohair that secures the effect of preventing the invasion of insects from the gap and further reduces sliding resistance to prevent the tip portion from spreading, and a screen door equipped with this mohair. is there.

The present invention that has solved the above problems is as follows.
<Invention of Claim 1>
The invention according to claim 1 is a mohair comprising a flat base and a pile group attached to the base and formed from a plurality of piles, wherein the pile group is in the height direction of the pile. The mohair is characterized by being bound so as to be squeezed toward the inner side in the width direction at an intermediate position.

<Invention of Claim 2>
The invention according to claim 2 is that the piles are sewn together with a plurality of bundles at a middle position in the height direction of the piles, and the whole pile group is bound by binding the bundles together. The mohair according to claim 1.

<Invention of Claim 3>
The invention according to claim 3 is the mohair according to claim 1 or 2, wherein the intermediate position in the height direction of the pile is a height of ¼ to ３ of the entire pile length from the base end side of the pile. is there.

(Function and effect)
Although the tip of the mohair tends to spread as the pile hairs become longer, in the present invention, the pile group is bound at the middle position in the pile height direction so as to be squeezed inward in the width direction. By doing so, the spread (unevenness) of the tip portion can be suppressed. Moreover, even if it is a thin pile, even if it lengthens a bristle foot, it can prevent a waist break and can become independent, Therefore It becomes possible to use the thin pile which was not used conventionally.
As a result, for example, when used as a screen door tight material, the contact area with the sash (including shoji) is reduced, and when opening and closing the screen door or shoji, the narrow portion between the screen door and the sash is used. Since the contact is supple, opening and closing operations are facilitated. In addition, since the pile group becomes stiff, even when the gap in contact with the sash is narrow due to the opening and closing of the screen door, an appropriate restoration property can be obtained when the pile group is restored after movement. In addition, the design is improved because there are few variations and disturbances at the tip of the pile group.
Even when the mohair according to the present invention is wound up in a long time at the time of packing, the mohair formed on the screen door has no variation (expansion) at the tip portion and little meandering when attached to the screen door. Easy to insert into the mounting groove.
As a method for binding the pile group, it is preferable to bind the pile group as a whole by binding the piles together with a thread at a middle position in the pile height direction and binding the bundles together. It is.
The intermediate position in the pile height direction is preferably set to a height of ¼ to ３ of the entire pile length from the base end side of the pile (opposite side to the tip of the pile).

<Invention of Claim 4>
The invention according to claim 4 is a screen door in which four laps are constituted by an upper heel, a lower heel, a right vertical ridge, and a left vertical ridge, and an insect screen is stretched, and any one of claims 1 to 3 A screen door in which the mohair described is attached to a right downspout and a left downspout, respectively.

  According to the present invention, it is possible to obtain an advantage that, for example, the effect of preventing the invasion of insects from the gap can be ensured, and the sliding resistance can be further reduced to prevent the tip portion from spreading.

Embodiments of the present invention will be described below.
<Mohair>
The mohair 1 according to the present invention is used as a sealing material that closes gaps in joinery such as screen doors, and mainly ensures the effect of preventing insects from entering through the gaps. As shown in FIGS. 1 to 3, the mohair 1 according to the present invention includes a flat base 2 having a rising portion 2A, and a plurality of piles 3a, 3a,. And a pile group 3 to be formed. And in the intermediate part of the height direction of the pile 3a, the pile group 3 is bundled so that it may squeeze toward the width direction inner side with the thread | yarn 4. Specifically, as shown in FIG. 2, the piles 3a are sewn together by a thread 4 in a bundle of plural pieces, and the bundles 3 are bound together, so that the entire pile group 3 is bound.

  As a raw material of the base 2 and the pile 3a, a general thing may be sufficient, For example, nylon fiber other than PP (polypropylene) is suitable. By making the material of the base 2 and the pile 3a the same, it becomes easy to plant the hair. Generally, mohair piles used for sashes including screen doors are 15T to 50T (T: "Decitex". The unit representing the thickness of the yarn is the number of grams per 10,000 m.). A thin pile is flexible and has a low sliding resistance even in a narrow gap to be closed. Therefore, it is easy to open and close the shoji and screen door, but it does not stand up if the waist is weak and the hair is long. On the other hand, a thick pile is rigid and easy to stand by itself, but lacks flexibility.

  On the other hand, in the present invention, even thinner piles can be used. As the pile 3a of the mohair 1, for example, a thin pile of about 10T to 15T is used, and the middle part of the pile group 3 is bound by the yarn 4, thereby being flexible. It is easy to be independent while having. As the mohair 1 according to the present invention, various types of piles can be used regardless of the thickness of the pile and the strength of the pile (strength of the waist).

  As the thread 4 to be sewn, a thread of a known material can be used. As for the binding method, as described above, a known method may be used as long as the piles 3a are sewn in a bundle of plural pieces and the bundles can be bound together. Bundling is performed at an intermediate position in the height direction of the pile 3a. However, considering the rigidity of the pile group 3, the appearance of the distal end portion, ease of assembling the screen door, reduction of sliding resistance, etc., the proximal end side of the pile 3a Therefore, it is preferable to carry out at a position of about 1/4 to 1/3 of the entire pile length. In the embodiment shown in the figure, the binding is performed at one place (one stage) at the intermediate position of the pile 3a, but the binding may be performed at a plurality of places (a plurality of stages). In addition, instead of sewing with the thread 4, the side portion at the intermediate position of the pile group 3 may be bound by welding, but there are problems such as that only the side portion can be bound, and that the tip portion tends to spread with a thin pile. Easy to come out. Therefore, as described above, sewing with a thread is preferable.

  Conventionally, a pile height (hair length) that can stand on its own with a 15T pile (the waist length does not break) is 8 mm, and if a higher height is required, a thicker pile must be used. However, in the present invention, by binding the intermediate position of the pile so as to squeeze inward in the width direction, the pile can be made independent even when the pile height is high, such as a thin pile (for example, 15T), and a thinner pile. (For example, 10T) can be made independent and can be used as a mohair with improved flexibility.

  As a result, the pile group 3 can be made independent while having flexibility, the tip portion is compactly compacted, the contact area with the sash (including shoji) is reduced, and when opening and closing the screen door and shoji. Since the contact at the narrow part between the screen door and the sash becomes flexible, the opening / closing operation becomes easy. Further, since the pile group 3 becomes strong, even if the gap contacting the sash is narrow due to opening and closing of the screen door, an appropriate restoration property when the pile group is restored after movement can be obtained. Furthermore, since there are few variations and disorder of the front-end | tip part of the pile group 3, the design property is also improved.

  Although the mohair is packed in a wound state and opened at a screen door assembly factory or the like, in the case of the mohair 1 according to the present invention, even if it is wound in a long length during packing, Since there is no variation (expansion) of the tip portion and it is difficult to cause winding gusset, it is easy to insert into the mohair mounting groove formed on the screen door. Since the shape is constant even when attached to the screen door, it is easy to grip the mohair in the automatic machine, and therefore it is easy to insert the mohair into the screen groove. On the other hand, since the shape of the mohair is narrowed even by manual work, it is easy to check the base end portion of the mohair, so that it can be easily inserted into the mohair mounting groove and the work efficiency is improved.

  The shape of the base 2 may be flat, but it is easier to make the pile 3a self-supporting by providing the rising portion 2A and planting the pile 3a therebetween. Further, if necessary, a film (not shown) made of PP or the like is attached so as to cover the base end portion of the pile group 3 and integrally sewn, so that it becomes easier to be self-supporting and an effect of blocking airflow is also produced. .

<Example>
Below, the mohair which concerns on this invention and the mohair of the prior art example were compared.
The mohair of the conventional example which does not sew an intermediate part is the mohair which planted pile length (hair length): 15mm, thickness: 23T, and material: PP (polypropylene). The base width was 4.5 mm, the pile group base end width was 1.5 mm, the spreading width of the tip portion was 12 to 18 mm, and the tip was disordered and spread.

  On the other hand, the mohair according to the present invention has a pile length (hair length): 15 mm, a thickness: 15 T, a material: PP (polypropylene) planted, and an intermediate portion in the height direction (about 5 mm from the base end side). Mohair sewn over its entire length. Despite the thickness of 15T, the spread width of the tip portion was 5 mm, and there was no significant pile disturbance or meandering, and the design was good even when attached to a screen door.

<Screen door using mohair>
Next, a screen door using the mohair according to the present invention will be described. In this embodiment, the screen door is attached to a sliding sash, but this screen door can also be used for various types of sashes such as a one-way sash and a two-way sash.

  As shown in FIGS. 4 and 5, the sliding sash forms a frame with a lower frame 20, an upper frame 21, a left vertical frame 22, and a right vertical frame 23. 40 is attached and the sash is configured.

  As shown in FIGS. 4 and 5, the screen door 11 according to the present invention includes an upper ridge 12, a lower ridge 13, a right vertical ridge 14, and a left vertical ridge 15, and four insects are stretched. Yes. In addition, you may attach the crosspiece 17 as needed.

  As shown in FIG. 4, a door 13 </ b> A is attached to the lower arm 13 so that it can move in the sash width direction while rotating on a rib-shaped screen door rail 20 </ b> A formed on the lower frame 20 of the sash. It has become.

  As shown in FIG. 4, a slip-off attachment 12 </ b> A for securing the screen door 11 is attached to the upper collar 12, and the rib-shaped screen door rail 21 </ b> A formed on the upper frame 21 of the sash is sandwiched. However, it can slide and move in the sash width direction.

  As shown in FIG. 5, mohair attachment grooves 14 </ b> A and 15 </ b> A are formed in the right vertical rod 14 and the left vertical rod 15 on the indoor side of each end portion in the width direction of the screen door 11. The mohair can be attached by inserting the base 2 into the mohair attaching grooves 14A and 15A. The mohair functions as a first tight material that abuts the summon 41 (right vertical rod) 41 of the external shoji 40 and the left vertical frame 22 of the sash frame.

  Moreover, the 2nd tight materials 18 and 18 of a fin member are provided in the inner peripheral side in the width direction of the screen door 11 rather than these mohairs 1 and 1. The first tight materials 1 and 1 and the second tight materials 18 and 18 extending in the vertical direction constitute a vertical insect-proof line.

  In the conventional one, since the mohair has high rigidity, the sliding resistance is high, and the screen door may move together with the opening and closing of the shoji. However, the mohair according to the present invention can use a thinner pile, so that the flexibility is improved and the sliding resistance can be suppressed. Therefore, the screen door can be prevented from moving due to opening and closing of the shoji.

  In addition, although this Embodiment demonstrated the case where it attached to the screen door, this invention is not limited to this, It can apply to various fittings.

It is a front view of the mohair concerning the present invention. It is the side view. FIG. It is a longitudinal cross-sectional view of the screen door and sash of one Embodiment using the mohair which concerns on this invention. FIG.
