Description

本発明は、主に中高層住宅や官庁舎等のベランダ内への鳩やカラスなどの害鳥の侵入防止に使用される防鳥ネットの取付器具に関し、とくに防鳥ネット同士を貼り合わせるために使用する防鳥ネット接合具に関するものである。   TECHNICAL FIELD The present invention relates to an attachment device for a bird net mainly used for preventing the invasion of harmful birds such as pigeons and crows into verandas of middle and high-rise houses and government buildings, and in particular, for bonding bird nets together. The present invention relates to an anti-bird net connector.

マンション等の中高層住宅では、特に空き室がある場合に鳩等の鳥が侵入して、ベランダの天井などに巣を作って棲みつくことがある。鳥がベランダの天井などに出入りするようになると、ベランダの手すりから糞を排出して、下階の干している洗濯物を汚したりする。また、鳥の糞は悪臭の原因になるばかりか、オウム病やクリプトコッカス病などの感染源になり衛生上好ましくない。これに対処する方法として、防鳥ネットを張って鳥の侵入を阻止する方法がある。   In middle-to-high-rise houses such as apartments, especially when there are vacant rooms, birds such as pigeons may invade and form nests on ceilings of verandas and collect them. When the birds come in and out of the ceiling of the veranda, excrement is drained from the handrail of the veranda, and soils the dried laundry on the lower floor. Moreover, bird droppings not only cause odor but also become infection sources such as parrot disease and cryptococcosis, which are not preferable for hygiene. As a way to cope with this, there is a method in which a bird net is stretched to prevent the invasion of birds.

従来の防鳥ネットとしては、一般にカスミ網や金属網から構成したものが広く知られている。しかし、カスミ網製のものでは、網目に鳥の首が絡まって死亡させるという欠点があった。また、カスミ網は細くて強度が比較的低いため、鳥によって網が破れやすいという欠点があった。一方、ステンレス等の金属網製のものでは、ネットの存在が外部から目立ちやすく外観体裁が悪く、しかもネット自体が重いため、万一、ネットが落下した場合は危険である。これを防止するためには、ネットの支持構造を頑丈にすればよいが、この場合にはネットの取付け取外し作業に多大な手間がかかる。また、例えば、ゴルフ練習用のネット等の他の設備で用いられているネットを流用しているものも多く、その色も様々である。   As conventional bird nets, those constructed from a mesh net or metal net are generally known. However, the one made by Kasumi net has a drawback that the neck of the bird gets caught in the net and kills it. In addition, since the mesh is thin and relatively low in strength, there is a drawback that the mesh is easily broken by birds. On the other hand, if the net is made of metal mesh such as stainless steel, the presence of the net is noticeable from the outside and the appearance is bad, and furthermore, the net itself is heavy. In order to prevent this, it is sufficient to make the support structure of the net robust, but in this case, it takes a lot of time to attach and detach the net. In addition, for example, many nets used in other facilities such as a net for golf practice are used, and the colors are also various.

例えば、特許文献1には、極細、軽量なネットを、マンションのバルコニーの上下に取り付けたレールの間にカーテン式に開閉自在に展張し、ネットの合わせ目はレールを重複させてマグネット付ランナーにより着脱自在にされた防鳥マットが開示されている。また、ポリエチレン製のテグス網によりなり、網目のサイズは鳥の首よりも小さい20ミリとされ、ネットの上下端部は、アンカーが埋設されたコンクリート部に、二枚のアルミニウム板で挟持し、これらのアルミニウム板を介してネジ釘で固定されて中高層住宅の空室ベランダに張られた防鳥ネットなども提案されている(特許文献2参照。)。   For example, according to Patent Document 1, an extra-thin, light-weight net is extended in a curtain-like manner between rails attached to the upper and lower sides of a balcony of an apartment, and the seam of the net overlaps the rails and the runner with a magnet is used. A removable bird mat is disclosed. In addition, it is made of polyethylene tegus mesh, and the mesh size is 20 mm smaller than the bird's neck, and the upper and lower end of the net is sandwiched between two aluminum plates in the concrete part in which the anchor is embedded, A bird net and the like are also proposed, which are fixed with screws through these aluminum plates and stretched on a vacant veranda of a middle-high-rise residence (see Patent Document 2).

こうした防鳥ネットを固定する装置や冶具として、取付基体Mに接着又はねじ止めする略板状の硬質合成樹脂成型物からなる取付チップに、鳥止まり防止ピンを起立状態に保持させるピン挿通孔と、防鳥ネットの掛止フック具を係着させる差込みゲートとが一体形成されてなるもの(特許文献3参照。)。平板状のベース体と、ベース体に取付けられた係止体にネット挿通させて、ロック体で固定するもの(特許文献4参照。)。また、防止ネットではないが、特許文献5には、台車上の荷崩れを防止するネットに対する固定部と、伸縮紐とカゴ固定部からなり、ネット固定部は強靭な布片からなる本体と、相互に着脱可能な面ファスナー片とからなり、ネット目から本体を潜らせてネットの外枠に対して一対の面ファスナー片同士を付着させて係止具をネットに固定するものが提案されている。   As a device or jig for fixing such a bird-proof net, a pin insertion hole for holding a birdcage prevention pin in an upright state and a mounting tip made of a substantially plate-like hard synthetic resin molding adhered or screwed to a mounting base M And an insertion gate for engaging a hook of a bird-proof net, which is integrally formed (see Patent Document 3). A plate-like base body and a locking body attached to the base body are inserted into a net and fixed with a lock body (see Patent Document 4). In addition, although not a prevention net, according to Patent Document 5, a fixing portion for a net that prevents a load collapse on a bogie, an expansion cord and a cage fixing portion, the net fixing portion is a main body made of a strong cloth piece, It has been proposed that it consists of mutually removable surface fastener pieces, allowing the main body to go down from the net eye to attach a pair of surface fastener pieces to the outer frame of the net and fix the locking tool to the net. There is.

一方、建物の角部や延長部分で複数枚のネット同士を貼り合わせる際には、その端部同士を編紐等を用いて縫合する必要があるが、縫合作業に多大な労力や習熟を要する。そこで、例えば、ガラリ等の通風口内へ防鳥ネットを取り付けるために、帯状に伸びた第1板状部2と、所定の間隔を挟んで第2板状部3と、第1板状部2に対向する第2板状部3と、第1板状部2と第2板状部3の間に形成された溝部4を有し、第1板状部2および第2板状部3には溝部4へ向いて突き出た複数の突起5が長さ方向に沿って設けられている建築用金網保持部材1が開示されている。(特許文献6参照。)。   On the other hand, when pasting together a plurality of nets at a corner or extension of a building, it is necessary to sew the ends together using a braid or the like, but a great deal of labor and learning is required for the suturing operation . Therefore, for example, in order to attach a bird-proof net to a ventilating opening such as a gully, the first plate-like portion 2 extended in a band shape, the second plate-like portion 3 with a predetermined interval interposed therebetween, and the first plate-like portion 2 And a groove 4 formed between the first and second plate-like parts 2 and 3, and the first and second plate-like parts 2 and 3 Is a building wire mesh holding member 1 in which a plurality of projections 5 protruding toward the groove 4 are provided along the length direction. (See Patent Document 6).

また、構成する単位面の隣り合うネット端同士を帯状に重ね合わせ、重ね合わせて二重になった帯状部分に縦方向に、編み込んで固着化した部分と編み込まずに固着しない部分を交互に配し、ネットの縛りつけ等の解除や、ファスナーの取り外し、別のネット等の覆いの解除等することなく、単位面間を離間させての開口部に手や器具を挿入しての、農作物の手入れ作業ができるようにした防鳥ネットが開示されている(特許文献7参照。)。   In addition, adjacent net ends of the unit surfaces to be combined are overlapped in a strip shape, and a portion formed by weaving and fixed and a portion not fixed without knitting are alternately arranged in the longitudinal direction in the overlapped strip portion. And maintenance of crops by inserting hands and tools into the opening with the unit faces separated, without releasing the binding of the net, removing the fastener, releasing the cover of the other net, etc. There is disclosed a bird net that has been made to work (see Patent Document 7).

特許文献8には、被取付け部材のフランジを挟むように側方から見てU字状に形成され、両端に第1端部および第2端部を有するクリップ部と、第1端部に、防鳥ネットを取付け可能に設けられた保持部とを備え、クリップ部は、第1端部を含む第1アーム部と、第2端部を含む第2アーム部と、第1アーム部および第2アーム部をつなぐ連結部とを有し、第1端部と第2端部との間隔が、第1アーム部における連結部側の端部と第2アーム部における連結部側の端部との間隔よりも小さくされた防鳥ネット取付具が開示されている。   In Patent Document 8, a clip portion formed in a U shape as viewed from the side so as to sandwich a flange of a mounting member, has a first end and a second end at both ends, and a first end, The clip unit includes a first arm including a first end, a second arm including a second end, a first arm, and a first clip. And a connecting portion connecting the two arm portions, and a distance between the first end portion and the second end portion is an end portion on the connecting portion side of the first arm portion and an end portion on the connecting portion side of the second arm portion An anti-bird net fitting is disclosed which is smaller than the distance between the two.

しかしながら、上記従来の器具を用いてもネットを緊張状態に体裁よく張る作業は相当の熟練を要し、施工場所によっては危険な作業となる。また、ネット同士の接合部に弛緩があるとその部分から害鳥が侵入するおそれがあるばかりでなく、防鳥ネットの張替作業も困難になる。
そこで、本発明は、熟練した作業者でなくとも簡単に取り付けることができ、自然な状態で勝手に外れず、防鳥ネットの張設状態を容易に微調整ができ、製造コストの低減を図り得ると共に、軽量で耐久性に優れ、ネットの接合作業を簡便に行うことができる防鳥ネットの接合具を提供することを目的とする。
However, even if the above-mentioned conventional equipment is used, the work of tensioning the net requires considerable skill, and it may be dangerous depending on the construction site. In addition, if there is relaxation at the junctions between the nets, not only there is a possibility that the harmful birds may invade from that part, but also the reworking work of the avian nets becomes difficult.
Therefore, the present invention can be easily attached even by a non-skilled worker, can not be removed naturally in a natural state, can easily fine-tune the installation of the bird net, and reduce the manufacturing cost. It is an object of the present invention to provide a bird's-eye net joining tool which is lightweight, has excellent durability, and can be easily joined to the net.

A protrusion for preventing inward expansion is provided on at least one side of the first plate portion or the second plate portion, and a length of either one of the first plate portion or the second plate portion is the other. The first feature is that the length is shorter than the length. A second feature is that anti-slip portions formed of a plurality of grooves are provided on the outer periphery of the first plate portion and the second plate portion. Furthermore, it is a third feature that the plurality of connectors are made of hard synthetic resin and integrally molded with the runner frame so as to be separable.

防鳥ネットが対象とする鳥は、主に鳩と同等の大きさまたはこれよりも小さい鳥である。防鳥ネットの設置場所は、鳥が飛来して巣を作りやすい所、例えば、集合住宅、商業ビル、学校、病院、廃棄物処理場、競技場、公共施設、橋梁、駅、神社仏閣、立体駐車場等である。   Birds targeted by bird nets are mainly birds of the same size as or smaller than doves.

以下、図面に示す実施例に基づいて本発明の実施の形態を説明する。   Hereinafter, an embodiment of the present invention will be described based on an example shown in the drawings.

図1乃至図3に示すように、本発明に係る防鳥ネット接合具1は、複数枚の防鳥ネット5を張設する際に、防鳥ネット5の辺縁の網目部10a及び10b同士に掛け合わせて接合するものである。   As shown in FIGS. 1 to 3, when the plurality of bird protection nets 5 are stretched, the mesh parts 10 a and 10 b at the edge of the bird protection nets 5 are connected to each other. And they are joined together.

接合具1は、防鳥ネット5の辺縁部10a及び10b同士を挟持するように、第1プレート部2aと第2プレート部2bとを側方視で略U字に屈曲したクリッププレート2の状態に形成され、第1プレート部2a又は第2プレート部2bの少なくともいずれか一方側に、内方に膨出する抜け止め用突部3を設けられる。   The joining tool 1 is a clip plate 2 in which the first plate portion 2a and the second plate portion 2b are bent in a substantially U shape in a side view so as to sandwich the edge portions 10a and 10b of the bird protection net 5 with each other. In the state, at least one side of the first plate portion 2a or the second plate portion 2b is provided with a retaining projection 3 which protrudes inward.

また、第1プレート部2a又は第2プレート部2bのいずれか一方の長さが他方の長さよりも寸法=dの長さ分短尺とされている。また、第1プレート部2a及び第2プレート部2bの外周に複数の溝条から形成される滑り止め部4が設けられている。   Further, the length of either one of the first plate portion 2a or the second plate portion 2b is shorter than the other by the length of dimension d. Further, anti-slip portions 4 formed of a plurality of groove lines are provided on the outer periphery of the first plate portion 2a and the second plate portion 2b.

図4に示すように、複数の接合具1はAES樹脂製で、ランナー枠5と枝節5aを介して人手により切離可能に一体成形されている。尚、材質はAES樹脂に限定されないことは言うまでもなく、所期の物性、すなわち、AES樹脂と同等の弾性と硬度を有する金属あるいはAES樹脂以外の合成樹脂、合金又はこれらのハイブリッド材料でもよい。また、複数の接合具1をランナー枠5ごと一体成型することで、製造コストの低減を図り得る。   As shown in FIG. 4, the plurality of bonding tools 1 are made of AES resin, and are integrally molded so as to be manually detachable via the runner frame 5 and the branch nodes 5a. The material is not limited to the AES resin, but may be a metal having desired physical properties, that is, elasticity and hardness equivalent to that of the AES resin, a synthetic resin other than the AES resin, an alloy, or a hybrid material thereof. In addition, by integrally molding the plurality of bonding tools 1 together with the runner frame 5, the manufacturing cost can be reduced.

すなわち、接合具1は、略U字に屈曲したクリッププレート2と網抜け防止ストッパの機能を奏する抜け止め用突部3とよりなり、AES樹脂等の硬質合成樹脂を射出成型して作られている。   That is, the connector 1 is composed of a clip plate 2 bent in a substantially U shape and a protrusion 3 for retaining that plays the function of a mesh-fall preventing stopper, and is made by injection molding a hard synthetic resin such as AES resin. There is.

ここで、本発明の接合具1と併用されるネット留め具6について説明する。
図5乃至図7に示すように、ネット留め具6は、基本的には、ベランダの前壁面8等の防鳥ネット5の被取付物に接着固定して使用される。ネット留め具6もまたポリカーボネート等の硬質合成樹脂の押し出し成型によって、平板矩形状のベース部6aと、ベース部6a上のドーム型(半球状)のフック部6bとを一体形成して構成されている。
Here, the net fastener 6 used together with the connector 1 of the present invention will be described.
As shown in FIG. 5 to FIG. 7, the net fastener 6 is basically used by being adhesively fixed to the attachment of the anti-bird net 5 such as the front wall surface 8 of the veranda. The net fastener 6 is also configured by integrally forming a flat rectangular base portion 6a and a dome-shaped (hemispherical) hook portion 6b on the base portion 6a by extrusion molding of a hard synthetic resin such as polycarbonate. There is.

ネット留め具6のベース体6aは、その四辺角端が弧状に面取りされると共に、各々の角部近傍面に透孔6dが穿設されている。この透孔6dは基本的には接着剤9が充填されるアンダーカット部として機能するが、取り付け状況に応じてアンカービス止め用の貫通孔としても使用できる。また、ベース体6aの裏面(接着面)には、接着効果を高めるためのザラザラした砂状面や鑢面等の粗面に形成することが好ましい。   The base 6a of the net fastener 6 is chamfered in the shape of an arc at its four corners, and a through hole 6d is formed in the surface near each corner. The through hole 6d basically functions as an undercut portion to which the adhesive 9 is filled, but it can also be used as a through hole for anchoring with an anchor according to the mounting condition. Moreover, it is preferable to form in the back surface (adhesion surface) of the base body 6a in rough surfaces, such as a rough sand-like surface and a weir surface, in order to improve the adhesion effect.

すなわち、ベース部6a上には、防鳥ネット5の端部ロープ11の差込み溝6cを形成したドーム型のフック部6bが一体成形されている。フック部6bの差込み溝6cは、ロープ嵌装用の縦溝6fと連続して断面略L字状に形成され、この差込み溝6c内には、ネット端部ロープ11の抜け止め用の膨出部6eが設けられている。この膨出部6も下方に向かって凸となる弧面を有する略楕円弧形状に形成されており、ネット端部ロープ11の挿脱着をスムーズに行うことができるばかりでなく、挿脱着時にネット端部ロープ11を傷つけたり切断したりすることがないようにされている。   That is, on the base portion 6a, a dome-shaped hook portion 6b in which the insertion groove 6c of the end portion rope 11 of the bird's-eye net 5 is formed is integrally formed. The insertion groove 6c of the hook portion 6b is formed continuously with the longitudinal groove 6f for fitting the rope into a substantially L-shaped cross section, and in this insertion groove 6c, a bulging portion for preventing the net end rope 11 from coming off 6e is provided. This bulging portion 6 is also formed in a substantially elliptic arc shape having an arc surface which is convex downward, and not only can the net end portion rope 11 be smoothly attached and detached, but also the net end at the time of insertion and detachment The section rope 11 is not damaged or cut.

図8は、建物の開口部としてマンションのベランダに複数枚の防鳥ネット5(5a,5b)を張設した状態を示している。防鳥ネット5は、ベランダの天井壁と前壁8各々の壁面に各々固着された複数のネット留め具6に、ネット5の上下端ロープを複数か所掛け止めするだけで簡単に固定できる。そして、防鳥ネット5(5a,5b)の辺縁同士を複数の接合具1で適宜挟持することで接合する。接合作業は、ランナー枠5から人手により個別に切離しながら順次接合すべき網目に掛け留めして、例えば、防鳥ネット5aと5bの角隅部7を形成するように嵌装する。このように、ランナー枠5から個別に切離しながら作業することで、接合具1の取付け向きの決定等の作業が簡便になり、作業中の接合具1の落下や紛失等を防止できる。   FIG. 8 shows a state in which a plurality of bird nets 5 (5a, 5b) are stretched on a veranda of an apartment as an opening of a building. The bird's-eye view net 5 can be easily fixed to a plurality of net fasteners 6 fixed respectively to the ceiling wall of the veranda and the front wall 8 by hooking the upper and lower end ropes of the net 5 at a plurality of positions. Then, the edges of the anti-bird net 5 (5a, 5b) are joined by appropriately holding them by a plurality of joining tools 1. The joining work is hooked on the mesh to be joined sequentially while being separated individually from the runner frame 5 by hand, and fitted so as to form, for example, the corner portions 7 of the bird nets 5a and 5b. As described above, the work such as determination of the attachment direction of the bonding tool 1 can be simplified by working while being separated from the runner frame 5 individually, and the dropping or loss of the bonding tool 1 during the work can be prevented.

また、防鳥ネット抜け防止用突起3が接合具1の内面に設けてあるので、一度掛合した防鳥ネット5(5a,5b)同士は自然な状態では勝手に外れない。また、防鳥ネット5(5a,5b)の一部に弛緩部分や緊張し過ぎた部分が発生したときにも、接合具1が掛合する網目の位置を変えるだけで、簡単に最適の張設状態に調整できる。また取り外しも簡便であるので、火災等の災害時には、接合部分を人手で簡単に外すことができ、避難や救助の妨げにならない。   In addition, since the anti-bird net detachment prevention projections 3 are provided on the inner surface of the bonding tool 1, the anti-bird nets 5 (5a, 5b) engaged once do not come off in a natural state. In addition, even when a relaxed portion or a portion that is over-tensioned occurs in a part of the anti-bird net 5 (5a, 5b), simply by changing the position of the mesh with which the connector 1 is engaged, the optimum tensioning can be easily achieved. It can be adjusted to the state.
