Description

本発明は、夏場に就寝中に蚊や虫に刺されることを防止するための大人用又は子供用のほろ蚊帳に関するものである。   The present invention relates to a mosquito net for adults or children for preventing mosquitoes and insects from being stabbed during sleep in summer.

従来、上ろくろに挿通した引紐の一端が下ろくろに固着され、引紐を引き上げて下ろくろを上ろくろへ係止することにより、親骨及び受骨が拡開するほろ蚊帳は拡開時に外周が方形に形成されるものが殆んどである。
特に幼児用のほろ蚊帳では小型で長方形のものが多く、成長の早い幼児では2〜3年で頭や足がほろ蚊帳の開口縁に支えて使用ができなくなってしまう。
そこで、図3に示すように、長年使用できるよう拡開時に外周が長方形のほろ蚊帳の短辺側の対辺に張り出し部Aが形成されるよう親骨2の中間に中骨3が設けられた六角形ほろ蚊帳が使用されている。
Conventionally, one end of the drawstring inserted through the upper crosspiece is fixed to the lower crosspiece, and by pulling up the drawstring and locking the lower crosspiece to the upper crosspiece, the mosquito net that expands the main bone and the receiving bone is square when the outer circumference is expanded Most of them are formed.
In particular, small mosquito nets for infants are often small and rectangular, and in fast-growing infants, the head and feet can be supported by the opening edge of the mosquito net in two to three years.
Therefore, as shown in FIG. 3 , the middle bone 3 is provided in the middle of the main bone 2 so that the overhanging portion A is formed on the opposite side of the short side of the mosquito net whose outer periphery is rectangular when expanded so that it can be used for many years . A square mosquito net is used.

このほろ蚊帳は、三角形となる張り出し部Aに幼児の頭と足が位置するよう寝かせることで十分にその使用目的を達するもので、中骨3の先端部までの長さを長辺側とする長方形に比べて使用場所のスペースも少ないと共に、カバーを張設する箇所も少なくて済み無駄がないので好まれている。   This mosquito net can achieve its purpose of use by laying the infant's head and feet on the overhanging part A which is a triangle, and the length to the tip of the middle bone 3 is the long side. It is preferred because it uses less space than a rectangle and requires less space to stretch the cover, so there is no waste.

一方、ほろ蚊帳の張骨は、従来は同一太さの細い棒材で構成されており、これが前記構成のほろ蚊帳も親骨2と中骨3を同一太さの細い棒材で構成されているため、ほろ蚊帳を拡開した時に、中骨3とその両側の親骨2の間の狭いスペースに親骨2からのカバー11の張力が働くと中骨3がこれに抗するので、親骨2が図3の矢印イの如く中骨3側に引っ張られるため、中骨3は十分な撓みが得られず、そのため、ほろ蚊帳を拡開して使用すると、図4に示すように、中骨3の下端部が接地せずに中骨3が浮いた状態となり、この浮いた箇所から蚊などが侵入し、ほろ蚊帳としての機能を十分に発揮できないので、図5及び図6に示すように、カバー11の裾部にレースなどで縁飾り16を設け、この縁飾り16を垂らすことで浮いた箇所を塞ぎ、蚊などの侵入を防止していたのである。
なし
On the other hand, the tension bone of the mole mosquito net is conventionally composed of a thin bar material having the same thickness, and the mole mosquito net of the above configuration is composed of the main bone 2 and the middle bone 3 by a thin bar material of the same thickness. Therefore, when the cheek mosquito net is expanded, if the tension of the cover 11 from the main bone 2 acts on the narrow space between the intermediate bone 3 and the main bone 2 on both sides thereof, the intermediate bone 3 resists this, so that the main bone 2 is shown in FIG. As the arrow 3 in FIG. 3 is pulled toward the middle bone 3 side, the middle bone 3 cannot be sufficiently bent. Therefore, when the mosquito net is expanded and used, as shown in FIG. As shown in FIGS . 5 and 6 , since the lower end is not grounded, the middle bone 3 is in a floating state, and mosquitoes or the like enter from the floating portion and cannot fully function as a mosquito net . 11 A border 16 is provided on the bottom of the lace with a lace, etc. Technique, it had to prevent the entry of such as mosquitoes.
None

上記点より本発明は、拡開時に外周が方形の蚊帳の一方の対辺に張り出し部が形成されるよう、親骨の中間に中骨が設けられたほろ蚊帳の中骨が撓み易く使用時に中骨が浮くことを防止し、この浮いた箇所から蚊などが侵入することを防止したほろ蚊帳を提供しようとするものである。   In view of the above, the present invention makes it easy to bend the middle bone of the mosquito net provided with a middle bone in the middle of the parent bone so that a protruding portion is formed on one side of the mosquito net whose outer periphery is a square when expanded. It is intended to provide a mosquito net that prevents mosquitoes from invading from the floating area.

上記課題を解決するため本発明ほろ蚊帳は、拡開時に外周が方形の蚊帳の、一方の対辺に張り出し部が形成されるよう親骨の中間に中骨が設けられ、上ろくろに挿通した引紐の一端が下ろくろに固着され、引紐を引き上げて下ろくろを上ろくろへ係止することにより、親骨及び中骨と受骨が拡開すると共に、親骨及び中骨が、それぞれ上部と下部に折り畳み可能に連結されているほろ蚊帳において、上部の中骨又は下部の中骨のいずれかが親骨よりも細く形成されていることを特徴とするものである。 In order to solve the above-mentioned problems, the mosquito net of the present invention is a mosquito net whose outer periphery is a square shape, a middle bone is provided in the middle of the parent bone so that an overhang is formed on one side of the mosquito net, One end is fixed to the bottom and the pulling string is pulled up to lock the bottom to the top, so that the main bone, the middle bone, and the receiving bone expand , and the main bone and the middle bone can be folded at the upper and lower parts, respectively. In the mosquito net connected to , either the upper middle bone or the lower middle bone is formed to be narrower than the parent bone .

このような構成とすることにより、親骨及び中骨がそれぞれ上部と下部に折り畳み可能に連結されたほろ蚊帳であって、上部の中骨又は下部の中骨のみを親骨よりも細くすれば、細く形成した部分の中骨の抵抗力が小さくなり撓み易くなるので、中骨の下端は床、畳などの接地面に接地し浮き上がりが防止される。
したがって、折り畳み可能に連結されている中骨に着目し、中骨の強度への影響を最小限に止め一部分を細くするのみで、従来のように、浮き上がった箇所から蚊などが侵入することが防止され、ほろ蚊帳としての機能を十分に発揮できる効果を有する。
By adopting such a configuration, a cheek mosquito net in which the parent bone and the middle bone are foldably connected to the upper and lower parts, respectively, and if only the upper middle bone or the lower middle bone is made thinner than the parent bone, it becomes thinner. Since the resistance of the inner bone of the formed part becomes smaller and the body becomes easier to bend, the lower end of the inner bone contacts the grounding surface such as the floor or tatami to prevent the floating.
Therefore, focusing on the central bones that are connected in a foldable manner, mosquitoes can invade from the lifted point as before, by minimizing the effect on the strength of the central bone and making the part thinner. It is prevented, and has the effect of being able to fully function as a mosquito net.

以下、本発明の好ましい実施例について、添付図面を参照して説明する。
図1は本発明ほろ蚊帳の一実施の形態を示す一部省略した平面図、図2は図1の一部省略した部分正面図である。

図中1はほろ蚊帳の上ろくろであり、この上ろくろ1の鍔部1aに設けた放射状の溝に、基端部を針金などを介して4本の親骨2と、親骨2と同一長さの2本の中骨3が放射状かつ揺動自在に枢支されている。
親骨2又は中骨3は、従来通り親骨2は上ろくろ1に拡開時にほろ蚊帳の外周が方形となるように配設され、中骨3は親骨2と2本おきに親骨2間の中央部に配設され、この中骨3で方形のほろ蚊帳の一方の対辺に張り出し部Aが形成された六角形状のほろ蚊帳となる。親骨2と中骨3は可撓性を有する金属又は合成樹脂で断面が円形の細い棒材で構成されている。
In the figure, reference numeral 1 denotes a top of the mole net, and a radial groove provided on the collar 1a of the top 1 has four base bones 2 with the same length as the base bone 2 through a wire or the like at the base end. Are pivoted radially and swingably.
The main bone 2 or the middle bone 3 is arranged so that the outer circumference of the cheek mosquito net becomes a square shape when the main bone 2 is expanded on the upper skull 1 as usual, and the middle bone 3 is the center between the main bone 2 and every two main bones 2. A hexagonal mosquito net is formed in which the protruding portion A is formed on one side of the square mosquito net with the inner bone 3. The main bone 2 and the middle bone 3 are made of a thin bar having a circular cross section made of a flexible metal or synthetic resin.

4は下ろくろであり、この下ろくろ4の鍔部4aに設けた放射状の溝に一端を針金などを介して親骨2及び中骨3に対応する受骨5が揺動自在に枢支し、受骨5の他端は親骨2及び中骨3の上方部にかしめられて固定された継手6に回動可能にダボ7に枢着されている。
下ろくろ4の上ろくろ1を挿通可能な軸部4bの上端部に引紐8の一端が止着され、引紐8の他端は上ろくろ1を挿通し、つまみ9に固着されている。
また、軸部4bに軸部4bの側方に出入り自在に内装され、上ろくろ1の頭部1bの上面に係脱自在なハジキ10が設けられている。
Reference numeral 4 is a bottom wheel, and a receiving bone 5 corresponding to the main bone 2 and the middle bone 3 is pivotally supported by a radial groove provided on the collar 4a of the bottom wheel 4 via a wire or the like so as to be swingable. The other end of the receiving bone 5 is pivotally attached to a dowel 7 so as to be pivotable to a joint 6 that is caulked and fixed to the upper part of the parent bone 2 and the middle bone 3.
One end of the drawstring 8 is fastened to the upper end of the shaft portion 4 b through which the upper runner 1 can be inserted, and the other end of the drawstring 8 is passed through the upper runner 1 and fixed to the knob 9.
Further, a repellency 10 is provided on the upper surface of the head 1b of the top 1 so as to be able to enter and exit from the side of the shaft 4b.

11は親骨2及び中骨3に張設された網目状のカバーである。12は親骨2及び中骨3の下端部に嵌着された露先であり、カバー11を掛止している。   Reference numeral 11 denotes a mesh-like cover stretched around the main bone 2 and the middle bone 3. Reference numeral 12 denotes a tip that is fitted to the lower ends of the main bone 2 and the middle bone 3, and holds the cover 11.

親骨2は上部の親骨2aと下部の親骨2bに分離され、下部の親骨2bの上端部は上部の親骨2aの下端部に外方側へ回動可能に継手14で枢支連結されている。そして、上部の親骨2aと下部の親骨2bは同一太さとなっている。
また、中骨3も上部の中骨3aと下部の中骨3bに分離され、下部の中骨3bの上端部は上部の中骨3bの下端部に外方側へ回動可能に継手15で枢支連結されている。そして上部の中骨3aは下部の中骨3bよりも細く形成されている。下部の中骨3bは親骨2と同一の太さに形成されている。
The main bone 2 is separated into an upper main bone 2a and a lower main bone 2b, and an upper end portion of the lower main bone 2b is pivotally connected to a lower end portion of the upper main bone 2a by a joint 14 so as to be rotatable outward. The upper main bone 2a and the lower main bone 2b have the same thickness.
The middle bone 3 is also separated into an upper middle bone 3a and a lower middle bone 3b, and the upper end of the lower middle bone 3b is pivoted outwardly to the lower end of the upper middle bone 3b with a joint 15. It is pivotally connected. The upper middle bone 3a is formed thinner than the lower middle bone 3b. The lower middle bone 3 b is formed to have the same thickness as the parent bone 2.

このような構成を有するほろ蚊帳の引紐8を引き上げて、下ろくろ4の軸部4bを上ろくろ1に挿通し、ほろ蚊帳を拡開すれば、上部の中骨3が親骨2よりも細く形成されているのでカバー11の張力で容易に撓むため、図2に示すように、中骨3の下端部の露先12は床、畳などの接地面13に接地し浮き上がりが防止される。   By pulling up the pulling cord 8 of the mole net having such a configuration, inserting the shaft portion 4b of the lower skull 4 into the upper skull 1, and expanding the mole net, the upper middle bone 3 is formed thinner than the parent bone 2. Therefore, as shown in FIG. 2, the tip 12 of the lower end of the middle bone 3 contacts the grounding surface 13 such as a floor or a tatami to prevent the floating.

図面では上部の中骨3aの方が下部の中骨3bよりも細くなっているが、逆に上部の中骨3aを親骨2と同じ太さに形成し、下部の中骨3bを上部の中骨3aよりも細く形成してもよい。
細く形成されている中骨3bの太さは親骨2の太さにより異なるが、親骨2が直径約3.4mm程度の場合に中骨3は約2.8mm程度の太さに、また親骨2が直径約2.8mm程度の場合に中骨3は約2.5mm程度の太さにすると撓み易く接地可能となる。勿論、この太さ以下であればよく、何らこの数値に限定されるものではない。
In the drawing, the upper middle bone 3a is thinner than the lower middle bone 3b. Conversely, the upper middle bone 3a is formed to have the same thickness as the parent bone 2, and the lower middle bone 3b is formed in the upper middle bone 3b. It may be formed thinner than the bone 3a.
The thickness of the thinly formed middle bone 3b varies depending on the thickness of the parent bone 2, but when the parent bone 2 has a diameter of about 3.4 mm, the middle bone 3 has a thickness of about 2.8 mm, and the parent bone 2 When the diameter is about 2.8 mm, if the thickness of the middle bone 3 is about 2.5 mm, it is easy to bend and can be grounded. Of course, the thickness may be equal to or smaller than this thickness and is not limited to this value.
