Description

本発明は、自在柱式フェンスに関する。   The present invention relates to a universal column fence.

フェンスには、支柱に対する取付構造の違いにより間柱式フェンスと、自在柱式フェンスがある。前者は、フェンス長と等しい間隔で立設した支柱の対向面にフェンスの長手方向端部を近接してブラケットでフェンスを支柱に固定するものであり、後者は、任意の間隔で立設した支柱の正面にフェンスの長手方向中間部を近接して、ブラケットでフェンスを支柱に固定するとともに、隣接するフェンスの長手方向端部同士を連結部材により連結するものである。   There are two types of fences: a stud-type fence and a free-column-type fence depending on the mounting structure for the support. The former is a structure in which the fence is fixed to the support column with a bracket, with the end in the longitudinal direction of the fence approaching the opposing surface of the support column that is set up at intervals equal to the fence length. The fence is fixed to the support column with a bracket in close proximity to the front of the fence in the longitudinal direction, and the longitudinal ends of the adjacent fences are connected by a connecting member.

しかし、従来の自在柱式フェンスは、上框及び下框の中空部に連結部材を挿入して連結し、縦框同士を突き当てているだけであるため、隣接するフェンス端部同士の間に隙間が生じ、その隙間の一部を連結部材が横切る状態に位置する。そのため、その隙間と連結部材がフェンスの正面側及び背面側に露見されるため、フェンスの外観体裁が損なわれる。そのため、その隙間を隠蔽して美観の向上を図ったものが、例えば特許文献１に開示されている。   However, in the conventional free-column fence, the connecting members are inserted and connected to the hollow portions of the upper and lower cages, and only the vertical rods are abutted with each other. A gap is generated, and the connecting member crosses a part of the gap. Therefore, since the gap and the connecting member are exposed on the front side and the back side of the fence, the appearance appearance of the fence is impaired. For this reason, for example, Patent Document 1 discloses a technique for concealing the gap to improve the appearance.

しかしながら、特許文献１の自在柱式フェンスは、一方に開口する嵌合溝の底部の両端に係合溝を有する縦框を、前記係合溝が近接するように左右対称形に配置し、それらの両係合溝にジョイント部材を嵌合し、両縦框の外側からビスをねじ込んで縦框とジョイント部材を連結し、両縦框の嵌合溝にフェンスの端部を嵌合することにより、両フェンスの間に隙間が生じないようにしたものである。
特開２００２−８１２３０号公報 However, in the universal column fence of Patent Document 1, the vertical rods having the engagement grooves at both ends of the bottom of the fitting groove opened on one side are arranged symmetrically so that the engagement grooves are close to each other. By fitting joint members into both engagement grooves, screwing screws from the outside of both vertical fences to connect the vertical fences and joint members, and fitting the ends of the fence into the engagement grooves of both vertical fences The gap between the fences is not generated.
JP 2002-81230 A

上記先行技術は、２つの縦框を突き合わせ、両縦框の係合溝に挿入したジョイント部材に縦框の外側からねじ込んだビスで、２つの縦框とジョイント部材とを連結しているから、縦框の突き合わせ面に縦線が現れ、また、ビスが露出している。従って、見栄えの向上には限界があるとともに、ビスを多数用いるので、コストアップの原因となった。   In the above prior art, the two downboards and the joint member are connected with the screws screwed from the outside of the downboard into the joint members inserted into the engaging grooves of both downboards, with the two downboards butted. A vertical line appears on the butt face of the vertical fence, and the screw is exposed. Therefore, there is a limit to the improvement in appearance, and a lot of screws are used, which causes an increase in cost.

本発明は、隣接して連結されるフェンスの間に生じる隙間を隠蔽し、ビスを不要又はビスの使用数量を最小限にして、見栄えの向上とコストダウンを図るとともに、左右フェンスの連結強度の増大も可能な自在柱式フェンスを提供することを目的としている。   The present invention conceals gaps formed between adjacently connected fences, eliminates the need for screws or minimizes the number of screws used, improves appearance and reduces costs, and improves the connection strength of the left and right fences. The objective is to provide a universal column fence that can be increased.

(A2) Attaching upper and lower ridges having hollow portions on the upper and lower sides of the fence, and extending in the longitudinal direction both ends of the fence in the direction of the mating fence connected from both ends of the expected width, A vertical gutter having a pair of engaged edges having a locking claw at the tip is attached, (b2) a vertical plate having a shape equal to the cross-sectional contour shape of the upper gutter as the connecting member, and the vertical plate from each other An upper collar connecting member that extends to the opposite side and has an insertion portion that can be tightly fitted into the hollow portion of the upper collar, a vertical plate that has a shape equal to the cross-sectional contour of the lower collar, and a vertical plate A lower hook connecting member having an insertion portion extending to the opposite side and capable of being tightly fitted in the hollow portion of the lower hook, and a length equal to the vertical hook of the fence, and the prospect of the vertical hook A web portion having a length equal to the width and a flange portion extending in parallel to the web portion in a direction perpendicular to the web portion on opposite sides from both ends of the web portion, and having a substantially H-shaped cross section And having a fitting groove that opens in opposite directions between the flange portions and can tightly fit the vertical hook, and on the inner surface of the flange portion that forms one fitting groove, A vertical hook connecting member provided with a pair of engagement edges having a locking claw at the tip, and having an engagement edge having a locking claw at the tip on one inner surface of the flange portion forming the other fitting groove. And (c2) one insertion portion of the upper collar connecting member and one of the lower collar coupling member One of the two fences to be connected to the fitting portion is fitted into the upper hollow portion and the lower hollow portion of the fence, and a pair of engagement edges of the vertical hook connecting member are provided. The vertical fence of the one fence is fitted into the groove, the pair of engaged edges of the vertical fence are engaged with the pair of engagement edges of the vertical fence connecting member, and the locking claws are mutually connected. The vertical hook connecting member is locked and connected and fixed to the vertical hook of one of the two fences to be connected. (C2 ′) Next, the other insertion portion of the upper hook connecting member and the lower hook The other insertion portion of the connecting member is fitted into the hollow portion of the upper fence and the lower portion of the other fence of the two fences to be connected, respectively, and one engaging edge of the vertical hook connecting member The other fence of the two fences connected to the fitting groove provided with The vertical hook is engaged, and one of the pair of engaged edges of the vertical hook is engaged with one engaging edge of the vertical hook connecting member, and the locking claws are locked to each other to engage the vertical hook. The vertical fence of the other fence is connected and fixed to the hook connecting member.

請求項１の発明によれば、連結される両フェンスの縦框が長尺の連結部材の嵌合溝に嵌合されるから、連結部分に隙間や接触縦線が生じない。また、連結のためにビスを用いないので、連結部分にビスが露呈されない。従って、フェンスの美観が向上し、かつ、コスト低減効果が得られる。さらに、縦框が連結部材の嵌合溝に嵌合されるほか、縦框の一対の被係合縁が連結部材の一対の係合縁に係合し、固定されるので、両フェンスの連結強度が大きい。   According to the first aspect of the present invention, since the vertical hooks of the two fences to be connected are fitted into the fitting grooves of the long connecting member, no gap or contact vertical line is generated in the connecting portion. Further, since no screw is used for connection, the screw is not exposed at the connection portion. Therefore, the aesthetics of the fence is improved and a cost reduction effect is obtained. In addition, the vertical hook is fitted into the fitting groove of the connecting member, and the pair of engaged edges of the vertical hook are engaged with and fixed to the pair of engaging edges of the connecting member. High strength.

請求項２の発明によれば、連結される両フェンスの縦框同士の間の隙間が縦框連結部材により隠蔽されるばかりでなく、上框の端部同士の間及び下框の端部同士の間の隙間がそれぞれ上框連結部材と下框連結部材により塞がれるので、両フェンスの連結部分の上端から下端までの全部において隙間が露見することがないので、フェンスの美観が一層向上する。また、両フェンスは、上框連結部材と縦框連結部材と下框連結部材の３部材により連結されるので、フェンスの連結強度がさらに大きくなる。従来の自在柱式フェンスは、支柱間のフェンス連結強度が必ずしも十分でないという問題が解決される。   According to the invention of claim 2, not only the gap between the vertical fences of both fences to be connected is concealed by the vertical fence connecting member, but also between the ends of the upper fences and between the ends of the lower fences Since the gap between each of the fences is closed by the upper hook connecting member and the lower hook connecting member, the gap is not exposed from the upper end to the lower end of the connecting portion of both fences, so the aesthetics of the fence is further improved. . Moreover, since both fences are connected by three members, an upper hook connection member, a vertical hook connection member, and a lower hook connection member, the connection strength of a fence becomes still larger. The conventional free-column fence can solve the problem that the strength of fence connection between the columns is not always sufficient.

次に、本発明の実施の形態について、図面を用いながら説明する。

FIG.

図１において、１は地面に作られたフェンス設置用基礎であり、その基礎１に任意の間隔で支柱２Ｌ，２Ｒが立設され、左側の支柱２Ｌに左側のフェンス３Ｌがその長手方向中間位置において近接され、上下の既知のブラケット４，５により固定されている。また、右側の支柱２Ｒに右側のフェンス３Ｒがその長手方向中間位置において近接され、上下の既知のブラケット４，５により固定されている。   In FIG. 1, reference numeral 1 denotes a fence installation base made on the ground. Posts 2 </ b> L and 2 </ b> R are erected at an arbitrary interval on the base 1, and a left fence 3 </ b> L is positioned at an intermediate position in the longitudinal direction on the left post 2 </ b> L. And are fixed by upper and lower known brackets 4 and 5. Further, the right fence 3R is brought close to the right support column 2R at the intermediate position in the longitudinal direction, and is fixed by upper and lower known brackets 4 and 5.

そして、概略を説明すると、左右のフェンス３Ｌ，３Ｒの隣接する端部は、各フェンスの上框３ａ及び下框３ｂを除いた他の部分、すなわち、縦框３ｃ（図２参照）において、後述される縦框連結部材６により両フェンス３Ｌ，３Ｒの端部の間に隙間が現れないようにして連結されている。また、左右のフェンスの上框３ａの長手方向端部同士の間は、後述される上框連結部材７により、その間に隙間が現れないようにして連結されている。さらに、左右のフェンス３Ｌ，３Ｒの下框３ｂの長手方向端部同士の間は、後述される下框連結部材８により、その間に隙間が現れないようにして連結されている。縦框連結部材６、上框連結部材７、及び下框連結部８を順次詳細に説明する。   The outline of the adjacent ends of the left and right fences 3L and 3R will be described later in other parts excluding the upper and lower fences 3a and 3b of each fence, that is, the vertical fence 3c (see FIG. 2). The vertical rod connecting member 6 is connected so that no gap appears between the ends of the fences 3L, 3R. In addition, the longitudinal ends of the upper fences 3a of the left and right fences are connected to each other by an upper fence connecting member 7 described later so that no gap appears between them. Furthermore, the longitudinal ends of the lower rods 3b of the left and right fences 3L and 3R are connected by a lower rod connecting member 8 described later so that no gap appears therebetween. The vertical hook connecting member 6, the upper hook connecting member 7, and the lower hook connecting portion 8 will be sequentially described in detail.

縦框連結部材６は、図２に示すように、縦框３ｃと等しい長さを有する断面ほぼＨ字形の形材で形成され、中央のウェブ部６１と、そのウェブ部の両端部においてウェブ部と直角方向に伸びる両側のフランジ部６２，６３とを一体に有し、フランジ部６２，６３の間にウェブ部６１を境として互いに反対方向に開口する嵌合溝６４，６５を有している。   As shown in FIG. 2, the vertical hook connecting member 6 is formed of a substantially H-shaped cross section having a length equal to the vertical hook 3c, and includes a central web portion 61 and web portions at both ends of the web portion. And flanges 62 and 63 on both sides extending in a direction perpendicular to each other are integrally formed, and between the flanges 62 and 63, there are fitting grooves 64 and 65 that open in opposite directions with the web portion 61 as a boundary. .

フランジ部６２，６３のウェブ部６１に関して左右いずれか一方側の対向面に、外向きに突出する係止爪６６’，６７’を先端に有する一対のＬ字形の係合縁６６，６７がウェブ部６１から等距離の位置において設けられ、フランジ部６２のウェブ部６１に関して他方側のフランジ部６３と対向する面に、先端に爪６８’を有するＬ字形の係合縁６８がウェブ部６１から係合縁６６までの距離と等距離の位置において設けられている。係合縁６８はフランジ部６２ではなく、フランジ部６３にウェブ部６１から係合縁６７までの距離と等距離の位置に設けられても良い。   A pair of L-shaped engagement edges 66, 67 having locking claws 66 ', 67' projecting outward on the opposite surfaces on either the left or right side with respect to the web portion 61 of the flange portions 62, 63 are webs. An L-shaped engagement edge 68 provided with a claw 68 ′ at the tip is provided on the surface of the flange portion 62 facing the other flange portion 63 with respect to the web portion 61 of the flange portion 62. It is provided at a position equidistant from the distance to the engaging edge 66. The engaging edge 68 may be provided not on the flange portion 62 but on the flange portion 63 at a position equal to the distance from the web portion 61 to the engaging edge 67.

各フェンスの縦框３ｃには、図２に示すように、横断面ほぼ矩形の中空部３１の両端部から連結される他のフェンス方向に延出し、先端に内向きに突出する一対の係止爪３２’，３３’を有する被係合縁３２，３３が設けられている。係止爪３２’，３３’の最小間隔は、縦框連結部材６の一対の係止爪６６’，６７’の最大間隔よりもわずかに小さく設定されている。上記構成の縦框３ｃは、左右のフェンス３Ｌ，３Ｒの隣接する端部に、左右対称形に取り付けられている。   As shown in FIG. 2, the fence 3c of each fence has a pair of latches extending in the direction of another fence connected from both ends of the hollow portion 31 having a substantially rectangular cross section and projecting inward at the tip. Engaged edges 32, 33 having claws 32 ', 33' are provided. The minimum distance between the locking claws 32 ′ and 33 ′ is set slightly smaller than the maximum distance between the pair of locking claws 66 ′ and 67 ′ of the vertical hook connecting member 6. The vertical gutter 3c having the above configuration is attached to the adjacent ends of the left and right fences 3L and 3R in a symmetrical manner.

そして、縦框連結部材６は、隣接設置される左右のフェンス３Ｌ，３Ｒのいずれか一方に、次のようにして先に連結される。すなわち、縦框連結部材６の一対の係合縁６６，６７が設けてある側の嵌合溝６４を一方のフェンス（図２の例では左側のフェンス３Ｌ）の縦框３ｃに対向させ、一対の係合縁６６，６７をその縦框の被係合縁３２，３３と位置あわせをした状態で、その縦框連結部材６をその縦框３ｃ方向に強く押し付ける。各係止爪３２’，３３’；６６’，６７’はそれぞれテーパー面を有しているため、図２（ａ）に示されているように、縦框連結部材６の一対の係合縁６６，６７と被係合縁３２，３３とを容易にかつ緊密に係合させ、一対の係止爪６６’，６７’と一対の係止爪３２’，３３’とを互いに係止させることができる。この係合及び係止とともに、縦框３ｃが縦框連結部材６の両側のフランジ部６２，６３の間に緊密に嵌合する。そのため、縦框連結部材６は、その外面からビスを縦框３ｃにねじ込まなくても、一方のフェンス３Ｌに堅固に固定される。   The vertical hook connecting member 6 is first connected to one of the left and right fences 3L and 3R installed adjacent to each other as follows. That is, the fitting groove 64 on the side where the pair of engaging edges 66 and 67 of the vertical hook connecting member 6 is provided is opposed to the vertical hook 3c of one fence (left fence 3L in the example of FIG. 2). With the engaging edges 66 and 67 aligned with the engaged edges 32 and 33 of the vertical hook, the vertical hook connecting member 6 is strongly pressed in the direction of the vertical hook 3c. Since each of the locking claws 32 ′, 33 ′; 66 ′, 67 ′ has a tapered surface, as shown in FIG. 2 (a), a pair of engaging edges of the vertical hook connecting member 6 66, 67 and the engaged edges 32, 33 are easily and tightly engaged, and the pair of locking claws 66 ', 67' and the pair of locking claws 32 ', 33' are locked with each other. Can do. Along with this engagement and locking, the vertical rod 3 c is tightly fitted between the flange portions 62 and 63 on both sides of the vertical rod connecting member 6. Therefore, the vertical hook connecting member 6 is firmly fixed to the one fence 3L without screwing the screw into the vertical hook 3c from the outer surface thereof.

続いて、一方のフェンス３Ｌに固定された縦框連結部材６の１個の係合縁６８が設けられている嵌合溝６５に、他方のフェンス（図２の例では右側のフェンス３Ｒ）の縦框３ｃを、その両側の外面を縦框連結部材６の両側のフランジ部６２，６３の内面に位置あわせした状態を保って、その縦框３ｃを縦框連結部材６の嵌合溝６５に向けて移動し、嵌合させる。   Subsequently, the other fence (the right fence 3R in the example of FIG. 2) of the other fence (right fence 3R in the example of FIG. 2) is fitted into the fitting groove 65 provided with one engagement edge 68 of the vertical hook connecting member 6 fixed to the one fence 3L. The vertical rod 3c is maintained in a state in which the outer surfaces of both sides thereof are aligned with the inner surfaces of the flange portions 62, 63 on both sides of the vertical rod connecting member 6, and the vertical rod 3c is formed in the fitting groove 65 of the vertical rod connecting member 6. Move toward and fit.

この時、縦框連結部材６の嵌合溝６５の両側のフランジ部６２，６３の内面に係合縁６８が、嵌合溝６４における一対の係合縁６６，６７と同様に一対設けてある場合は、右側のフェンス３Ｒの位置あわせがわずかにずれていても、フェンスは長さを有するので、フェンスの微小位置調整は困難であるため、右側の縦框３ｃを嵌合溝６５に容易に嵌合することができない。しかし、後に縦框が嵌合される側の嵌合溝には１個の係合縁６８しか設けられていないので、右側のフェンス３Ｒの位置あわせがわずかにずれている場合でも、右側の縦框３ｃを嵌合溝６５に容易に嵌合することができる。   At this time, a pair of engaging edges 68 are provided on the inner surfaces of the flange portions 62 and 63 on both sides of the fitting groove 65 of the vertical hook connecting member 6 in the same manner as the pair of engaging edges 66 and 67 in the fitting groove 64. In this case, since the fence has a length even if the right fence 3R is slightly misaligned, it is difficult to finely adjust the position of the fence. Cannot be mated. However, since only one engagement edge 68 is provided in the fitting groove on the side where the vertical hook is fitted later, even if the right fence 3R is slightly misaligned, the right vertical The flange 3c can be easily fitted into the fitting groove 65.

そして、左右のフェンスが縦框連結部材６により連結された状態では、両フェンスの間に生じる隙間は、図２（ａ）に示されているように、縦框連結部材６の両側のフランジ部６２，６３により隠蔽されるから、フェンスの外観に隙間が露見することがない。また、縦框連結部材６は、ビスを用いずに縦框３ｃと結合されるので、ビスがフェンスの外面に現れることもない。従って、フェンスの縦框連結部材６により連結される部分の外観及び美観が向上される。   In the state where the left and right fences are connected by the vertical hook connecting member 6, the gap generated between the fences is a flange portion on both sides of the vertical hook connecting member 6, as shown in FIG. Since it is concealed by 62 and 63, a gap does not appear in the appearance of the fence. Further, since the vertical hook connecting member 6 is coupled to the vertical hook 3c without using screws, the screws do not appear on the outer surface of the fence. Therefore, the appearance and aesthetics of the portion connected by the fence vertical connection member 6 are improved.

左右のフェンス３Ｌ，３Ｒが縦框連結部材６により上述したように連結される前に、両フェンスの上框３ａの隣接する長手方向端部の一方には、図５に示された上框連結部材７が、予め取り付けられる。
上框連結部材７は、合成樹脂成型品であり、長手方向中間位置に薄い垂直板７１を有する。この垂直板の輪郭形状は、フェンスの上框３ａの外形とほぼ等しく形成されている。上框連結部材７は、その垂直板７１の上部から左右方向に、すなわち、互いに反対方向に等しい距離まで延出する挿入部７２を有する。挿入部７２は、一例として、断面ほぼ矩形の中空部７２ａとその中空部の下側両端部から下方に延びる脚部７２ｂとを有し、例えば、挿入部の外周面に長手方向に連続する又は間欠的なリブを形成して、所要の弾性と摩擦係数を備えている。この弾性と摩擦係数は、挿入部７２を上框３ａの中空部に圧入でき、容易に抜脱しない程度の弾性と摩擦係数である。 Before the left and right fences 3L, 3R are connected by the vertical hook connecting member 6 as described above, one of the adjacent longitudinal ends of the upper hooks 3a of both fences is connected to the upper hook shown in FIG. The member 7 is attached in advance.
The upper collar connecting member 7 is a synthetic resin molded product, and has a thin vertical plate 71 at an intermediate position in the longitudinal direction. The contour shape of the vertical plate is formed to be substantially equal to the outer shape of the upper fence 3a of the fence. The upper collar connecting member 7 has an insertion portion 72 extending from the upper part of the vertical plate 71 in the left-right direction, that is, to an equal distance in the opposite direction. As an example, the insertion portion 72 includes a hollow portion 72a having a substantially rectangular cross section and leg portions 72b extending downward from both lower end portions of the hollow portion. For example, the insertion portion 72 is continuous with the outer peripheral surface of the insertion portion in the longitudinal direction or Intermittent ribs are formed to provide the required elasticity and coefficient of friction. The elasticity and the friction coefficient are such that the insertion portion 72 can be press-fitted into the hollow portion of the upper collar 3a and is not easily removed.

このような形状の上框連結部材７は、垂直板７１の一方側の挿入部を、予め一方のフェンス、例えば図１の左側のフェンス３の上框３ａの中空部に圧入し、他方の挿入部をその上框３ａの端部から突出させた状態で取り付けられ、摩擦力により保持される。必要により、上框の裏面からビスＢ１で固着しても良い。   The upper hook connecting member 7 having such a shape presses the insertion portion on one side of the vertical plate 71 into one hollow in advance, for example, the hollow portion of the upper hook 3a of the left fence 3 in FIG. It is attached in a state where the portion protrudes from the end of the upper collar 3a, and is held by frictional force. If necessary, it may be fixed with a screw B1 from the back surface of the upper collar.

そして、上框連結部材７を取り付けた一つのフェンス（例えば、図１の左側のフェンス３Ｌ）の端部に、もう一つのフェンス（例えば、図１の右側のフェンス３Ｒ）を連結する際に、その上框連結部材７の上框３ａから突出されている残りの挿入部をそのもう一つのフェンスの上框の中空部に圧入することにより、又は必要により、上框の裏面からビスＢ１で固着することにより、両フェンスの上框３ａ同士が連結され、垂直板７１の外周部分は、その隣接する左右両側の上框の長手方向端面の間に挟まれ、両端面の間に生じる隙間を塞ぐ。従って、両上框の間には、図１に示されているように、薄い垂直板７１の外周部分のみが露見されるだけであるので、フェンスの上部の外観体裁が向上する。   And when connecting another fence (for example, the right fence 3R in FIG. 1) to the end of one fence (for example, the left fence 3L in FIG. 1) to which the upper fence connecting member 7 is attached, The remaining insertion portion protruding from the upper hook 3a of the upper hook connecting member 7 is pressed into the hollow part of the upper fence of the other fence or, if necessary, fixed with the screw B1 from the back face of the upper hook. By doing so, the upper fences 3a of both fences are connected to each other, and the outer peripheral portion of the vertical plate 71 is sandwiched between the longitudinal end surfaces of the upper and lower sides of the adjacent left and right sides, thereby closing the gap formed between the both end faces. . Therefore, as shown in FIG. 1, only the outer peripheral portion of the thin vertical plate 71 is exposed between the upper ridges, so that the appearance appearance of the upper part of the fence is improved.

また、左右のフェンス３Ｌ，３Ｒが縦框連結部材６により上述したように連結する前に、両フェンスの下框３ｂの隣接する長手方向端部の一方に、図６に示された下框連結部材８が、予め取り付けられる。
下框連結部材８は、上框連結部材７と同様の合成樹脂成型品であり、長手方向中間位置に薄い垂直板８１を有する。この垂直板の輪郭形状は、フェンスの下框３ｂの外形とほぼ等しく形成されている。そして、下框連結部材８は、その垂直板の上部及び下部から左右方向に、すなわち、互いに反対方向に等しい距離まで延出する挿入部８２、８３を有する。挿入部８２は、一例として、断面ほぼ矩形の中空部８２ａとその中空部の底部分を共有して横断面下方開口コ字形の脚部８２ｂとを有し、また、挿入部８３は、挿入部８２の脚部８２ｂと近似の横断面上方開口コ字形に形成されている。これらの挿入部８２，８３は、例えば、それらの外周面に長手方向に連続する又は間欠的なリブを形成して、所要の弾性と摩擦係数を備えている。この弾性と摩擦係数は、挿入部７２を上框３ａの中空部に圧入でき、容易に抜脱しない程度の弾性と摩擦係数である。 Further, before the left and right fences 3L and 3R are connected by the vertical hook connecting member 6 as described above, the lower hook connection shown in FIG. 6 is connected to one of the adjacent longitudinal ends of the lower hooks 3b of both fences. The member 8 is attached in advance.
The lower eyelid connecting member 8 is a synthetic resin molded product similar to the upper eyelid connecting member 7, and has a thin vertical plate 81 at an intermediate position in the longitudinal direction. The contour shape of the vertical plate is formed to be substantially equal to the outer shape of the lower fence 3b of the fence. The lower collar connecting member 8 has insertion portions 82 and 83 extending from the upper and lower portions of the vertical plate in the left-right direction, that is, to the same distance in the opposite directions. As an example, the insertion portion 82 has a hollow portion 82a having a substantially rectangular cross section and a leg portion 82b having a U-shaped transverse opening that shares a bottom portion of the hollow portion. It is formed in a U-shape with an upper side of an approximate cross section of the leg portion 82b of 82. For example, these insertion portions 82 and 83 are formed with continuous or intermittent ribs in the longitudinal direction on the outer peripheral surface thereof, and have required elasticity and friction coefficient. The elasticity and the friction coefficient are such that the insertion portion 72 can be press-fitted into the hollow portion of the upper collar 3a and is not easily removed.

このような形状の下框連結部材８は、上框連結部材７と同様に、垂直板８１の一方側の上下の挿入部８２，８３を、予め一方のフェンス、例えば図１の左側のフェンス３の下框３ｂの中空部に圧入し、他方の挿入部をその下框３ｂの端部から突出させた状態で取り付けられ、摩擦力により保持される。必要により、下框の裏面からビスＢ２で固着しても良い。   The lower hook connecting member 8 having such a shape is similar to the upper hook connecting member 7 in that the upper and lower insertion portions 82 and 83 on one side of the vertical plate 81 are previously connected to one fence, for example, the left fence 3 in FIG. It is press-fitted into the hollow part of the lower collar 3b and attached with the other insertion part protruding from the end of the lower collar 3b, and is held by frictional force. If necessary, it may be fixed with screws B2 from the back side of the lower arm.

そして、下框連結部材８を取り付けた一つのフェンス（例えば、図１の左側のフェンス３Ｌ）の端部に、もう一つのフェンス（例えば、図１の右側のフェンス３Ｒ）を連結する際に、その下框連結部材８の下框３ｂから突出されている残りの挿入部をそのもう一つのフェンスの下框の中空部に圧入することにより、又は、必要により下框の裏面からビスＢ２で固着することにより、両フェンスの下框３ｂ同士が連結され、垂直板８１の外周部分は、その隣接する左右両側の下框の長手方向端面の間に挟まれ、両端面の間に生じる隙間を塞ぐ。従って、両下框の間には、図１に示されているように、薄い垂直板８１の外周部分のみが露見されるだけであるので、フェンスの下部の外観体裁も向上する。   And when connecting another fence (for example, the right fence 3R in FIG. 1) to the end of one fence (for example, the left fence 3L in FIG. 1) to which the lower fence connecting member 8 is attached, The remaining insertion portion protruding from the lower arm 3b of the lower arm coupling member 8 is pressed into the hollow portion of the lower arm of the other fence or, if necessary, fixed with the screw B2 from the back surface of the lower arm By doing so, the lower fences 3b of both fences are connected to each other, and the outer peripheral portion of the vertical plate 81 is sandwiched between the longitudinal end surfaces of the adjacent left and right lower fences to close the gap formed between both end faces. . Accordingly, as shown in FIG. 1, only the outer peripheral portion of the thin vertical plate 81 is exposed between the lower armpits, so that the appearance of the lower part of the fence is also improved.

以上のようにして、隣接する二つのフェンス３Ｌ，３Ｒが縦框連結部材６、上框連結部材７及び下框連結部材８を介して連結されて、支柱２Ｌ，２Ｒに固定された状態では、隣接する二つのフェンスの長手方向端部の間に生じる隙間のうち、縦框３ｃの間に生じ隙間は縦框連結部材６により隠蔽され、上框３ａの端部の間に生じる隙間は上框連結部材７の薄い垂直板７１により塞がれ、下框３ｃの端部の間に生じる隙間は下框連結部材８の薄い垂直板８１により塞がれるため、両フェンスの連結部分に隙間が現れない。上框及び下框については、ビスＢ１，Ｂ２で補助的に固着する場合でも、上框及び下框の裏面から固着されるので、また、ビス使用数量は最小限に止められる。従って、フェンス３Ｌ，３Ｒの外観体裁・美観が向上する。   As described above, when two adjacent fences 3L and 3R are connected via the vertical hook connecting member 6, the upper hook connecting member 7 and the lower hook connecting member 8 and fixed to the columns 2L and 2R, Of the gaps that occur between the longitudinal ends of two adjacent fences, the gap that occurs between the vertical fences 3c is concealed by the vertical fence connecting member 6, and the gap that occurs between the ends of the upper fence 3a is the upper gap. Since the gap between the ends of the lower rod 3c is blocked by the thin vertical plate 71 of the connecting member 7 and is blocked by the thin vertical plate 81 of the lower rod connecting member 8, a gap appears at the connecting portion of both fences. Absent. As for the upper hook and the lower hook, even if they are fixedly secured with the screws B1 and B2, they are fixed from the back surfaces of the upper and lower hooks, and the number of screws used is kept to a minimum. Accordingly, the appearance and appearance of the fences 3L and 3R are improved.

図１には、図面の簡略化のため、隣接する二つのフェンスして示されていないが、右側のフェンス３Ｒの右側にも、他のフェンスが順次同様にして連結される。   In FIG. 1, for simplification of the drawing, the two adjacent fences are not shown, but other fences are sequentially connected to the right side of the right fence 3R in the same manner.
