Description

本願発明は、道路側部の外側が段下げ状態で開放されている場所に設置される転落防止用ガード体に関するものである。尚、本願で表現している「道路側部の外側が段下げ状態で開放されている場所」とは、主として道路側部に設けた側溝内の開放部のことであるが、このほかに道路側部から段下げ状態で開放している開放部（例えば下に田畑がある）がある場所も含むものであって、人や自転車等が道路側部から開放部側に転落する危険がある場所のことである。   The present invention relates to a fall-preventing guard body installed at a place where the outside of a road side portion is opened in a step-down state. In addition, the “place where the outside of the road side is open in a step-down state” expressed in the present application is mainly an open part in a gutter provided on the side of the road. Including places where there is an open part that is open from the side in a step-down state (for example, there is a field below), there is a risk that people or bicycles may fall from the road side to the open part That is.

市街地のような交通量の多い道路の側溝は、安全上や路幅拡大等の観点から側溝の上部開放部を蓋体で被覆している場合が多い。そして、この種の側溝用被覆蓋としては、コンクリート製蓋や鋼製蓋（グレーチング）が多用されているが、該側溝用被覆蓋としてコンクリート製蓋や鋼製蓋を採用したものでは、材料費や製作費等のコストが高価になるとともに、重量が重いので取り扱いが面倒となる。特に、農業用水路や生活排水路等で水路幅が比較的広い（例えば７０cm〜１００cm程度）側溝では、そこに被覆する蓋単体の面積が大きくなることで１個当たりの蓋体重量が重くなり、水路内を掃除する際の蓋開放作業を人力で行えなくなることがある。   The side gutter of a road with a lot of traffic such as an urban area often covers the upper open part of the gutter with a lid from the viewpoint of safety and road width expansion. As this type of side groove cover, a concrete cover and a steel cover (grating) are often used. However, if a concrete cover or steel cover is used as the side groove cover, And manufacturing costs are expensive, and the weight is heavy, which makes handling difficult. In particular, in the side channel where the channel width is relatively wide (for example, about 70 cm to 100 cm) in agricultural waterways and domestic drainage channels, the lid weight per piece becomes heavier by increasing the area of the cover alone, It may become impossible to manually open the lid when cleaning the water channel.

又、側溝の被覆蓋の設置高さが道路面と同高さであると、自動車（大重量）が被覆蓋上に乗り上げることを考慮する必要があるので、該被覆蓋を更に頑丈なものにしなければならず、その結果、一層のコスト高となるとともに大重量になってしまう。   In addition, if the installation height of the cover cover in the side groove is the same as the road surface, it is necessary to consider that the automobile (heavy weight) rides on the cover cover. As a result, the cost is further increased and the weight is increased.

他方、交通量が少ない道路（例えば田舎の道路）の側溝には、被覆蓋のないものも多々ある。尚、水路内の掃除の容易性やコスト面では、側溝の上部開放部に被覆蓋の無い方が有利であることは当然である。   On the other hand, many of the side grooves of roads with low traffic volume (for example, rural roads) do not have a covering lid. Of course, in terms of ease of cleaning in the water channel and cost, it is natural that there is no cover lid in the upper open portion of the side groove.

ところが、被覆蓋がない側溝（上部開放水路）では、不注意で人や自転車等が水路内に転落する事故が発生し易くなる（全国で年間多数の転落者が発生しているのが実情である）。特に夜間の照明が乏しい場所では、側溝部分が見えづらくなるので、一層水路内への転落の危険性が増す。尚、道路側部に側溝が無い場合でも、道路側部の外側が段下げ状態で開放されている場所では、同様に開放部側への転落事故の危険性は生じる。   However, in a ditch without an open lid (upper open waterway), accidents in which people or bicycles inadvertently fall into the waterway are likely to occur. is there). Especially in places where night illumination is scarce, the side grooves become difficult to see, and the risk of falling into the waterway is further increased. Even when there is no gutter on the side of the road, there is a risk of a fall accident to the open side in a place where the outside of the road side is open in a stepped down state.

又、従来から道路側部外方の危険側（開放部）への転落防止用として、フェンスやガードレールを設置したものがあるが、これらのフェンスやガードレールは、道路側部においてかなりの高さを有している。従って、道路側部にフェンスやガードレールを設置した場合には、それによって道路の有効幅が実質的に狭くなるとともに、自動車や人が通行時に道路幅が狭く感じる（圧迫感を感じる）という難点がある。   In addition, some fences and guard rails have been installed to prevent falling to the dangerous side (open part) outside the road side, but these fences and guard rails have a considerable height on the road side. Have. Therefore, when fences or guardrails are installed on the side of the road, the effective width of the road is substantially narrowed, and the road width is narrow when a car or a person is passing (feels a sense of pressure). is there.

そこで、本件出願人は、道路側部の側溝の上部開放部を被覆するものとして図１２に示す側溝用被覆材を特許出願している。尚、図１２に示す側溝用被覆材は、特開２０１６−２０４８７３号公報（特許文献１）として開示されたものである。   Therefore, the present applicant has filed a patent application for a covering material for a side groove shown in FIG. 12 as covering the upper open part of the side groove on the road side. Note that the side groove covering material shown in FIG. 12 is disclosed in Japanese Patent Laid-Open No. 2006-204873 (Patent Document 1).

図１２に示す公知の側溝用被覆材１Ａは、それぞれ細線材からなる横線材２１，２１・・と縦線材２２，２２・・を縦横（格子状）に組付けてなる面状メッシュ体２Ａが使用されているが、この面状メッシュ体２Ａは、道路４の側部４１に設置されたＵ型の側溝５の水路幅Ｗに対応した幅Ｙ（側溝５の両側壁５２，５３の各上面５２ａ，５３ａに跨がる幅）で側溝長さ方向に所定長さを有した平面視矩形に形成されている。又、この側溝用被覆材１Ａの面状メッシュ体２Ａは、その上面側が緩やかな凸型に突出するアーチ状に成形されている。   The known side groove covering material 1A shown in FIG. 12 has a planar mesh body 2A formed by assembling horizontal wire materials 21, 21,... And vertical wire materials 22, 22,. Although used, this planar mesh body 2A has a width Y corresponding to the channel width W of the U-shaped side groove 5 installed on the side portion 41 of the road 4 (the upper surfaces of the side walls 52 and 53 of the side groove 5). 52a and 53a) and a rectangular shape in plan view having a predetermined length in the side groove length direction. Further, the planar mesh body 2A of the side groove covering material 1A is formed in an arch shape in which the upper surface side protrudes into a gently convex shape.

そして、この公知の側溝用被覆材１Ａは、図１２に示すように道路４の側部４１に設置された側溝５の上部開放部５１を全幅に亘って被覆するように設置される。その際、面状メッシュ体２Ａの幅方向一端部２ａは側溝５の道路側側壁５２の上面５２ａにヒンジで枢動開閉自在に取付ける一方、面状メッシュ体２Ａの幅方向他端部２ｂは側溝５の反道路側側壁５３の上面５３ａに単に載せているだけである。従って、水路清掃時には、面状メッシュ体２Ａの自由側端部２ｂ側を上方に弧回動開放させることで、水路内に人が入って清掃することができる。   And this well-known covering material 1A for side grooves is installed so that the upper open part 51 of the side groove 5 installed in the side part 41 of the road 4 may be covered over the full width, as shown in FIG. At that time, one end 2a in the width direction of the planar mesh body 2A is pivotally attached to the upper surface 52a of the road side wall 52 of the side groove 5 by a hinge, while the other end 2b in the width direction of the planar mesh body 2A is a side groove. No. 5 is simply placed on the upper surface 53a of the side wall 53 opposite to the road. Therefore, at the time of cleaning the water channel, the free side end 2b side of the planar mesh body 2A is arc-turned upward to allow a person to enter the water channel for cleaning.

この図１２に示す公知の側溝用被覆材１Ａ（面状メッシュ体２Ａ）では、細線材２１，２２を格子状に組付けたものであるから、安価に製作できるとともに軽量であるので水路清掃時に比較的軽作業で開閉でき、さらに設置状態で側溝用被覆材１Ａの上面高さが路面高さより僅かに（例えば１０〜１５cm）高い程度であるので、道路４の有効幅が実質的に狭くならず、しかも自動車や人が通行時に道路幅が狭く感じない、という各種の利点がある。   In the well-known side groove covering material 1A (planar mesh body 2A) shown in FIG. 12, the thin wire members 21 and 22 are assembled in a lattice shape. Since it can be opened and closed with relatively light work, and the height of the upper surface of the covering member 1A for the side groove is slightly higher (for example, 10 to 15 cm) than the road surface in the installed state, the effective width of the road 4 is substantially narrow. Furthermore, there are various advantages that the road width does not feel narrow when a car or a person passes.

特開２０１６−２０４８７３号公報JP, 2006-204873, A

ところで、道路側部に設置される側溝５の水路幅Ｗは、設置場所によって多種類のものが使用されている。因に、水路幅Ｗが３０cm〜１００cmの範囲の中でも、側溝５の水路幅サイズとして７〜８種類あるのが現状である。   By the way, as for the channel width W of the gutter 5 installed on the side of the road, various types are used depending on the installation location. Incidentally, there are currently 7 to 8 types of channel width sizes of the side grooves 5 in the range of the channel width W from 30 cm to 100 cm.

そして、図１２に示す公知の側溝用被覆材１Ａは、側溝５の両側壁５２，５３の各上面５２ａ，５３ａに跨がって設置される（即ち、面状メッシュ体２Ａの幅方向各端部２ａ，２ｂが側溝５の両側壁５２，５３の各上面５２ａ，５３ａに載せられる）関係で、側溝５の水路幅Ｗごとにそれぞれ対応した多種類（例えば７〜８種類）のサイズのものが必要となる。   12 is installed across the upper surfaces 52a and 53a of the side walls 52 and 53 of the side groove 5 (that is, each end in the width direction of the planar mesh body 2A). Since the portions 2a and 2b are placed on the respective upper surfaces 52a and 53a of the side walls 52 and 53 of the side groove 5, the sizes of various types (for example, 7 to 8 types) corresponding to the water channel width W of the side groove 5 respectively. Is required.

従って、図１２に示す公知の側溝用被覆材１Ａでは、設置された側溝５の各種水路幅Ｗごとに対応した多種類のサイズのものを製作する必要があるので、製品サイズの管理が繁雑になるとともに、施工依頼に対して早期に対応するには各種サイズの側溝用被覆材９Ａを前以て準備しておくことが必要となり、そのための在庫量（在庫種類点数）が多くなるという、難点があった。   Therefore, in the well-known side groove covering material 1A shown in FIG. 12, it is necessary to manufacture various types of sizes corresponding to various channel widths W of the installed side groove 5, so that the management of the product size is complicated. In addition, in order to quickly respond to the construction request, it is necessary to prepare the side groove covering material 9A of various sizes in advance, which increases the amount of inventory (the number of inventory types) for that purpose. was there.

そこで、本願発明は、道路側部の外側が段下げ状態で開放されている場所（側溝を含む）での開放部側への転落防止機能を有するもの（ガード体）として、軽量で且つ安価に製作でき、さらに歩行者や自動車・自転車の運転者等に危険個所があることの注意を容易に喚起させ得るとともに、単一サイズのもので広範囲の場所（側溝サイズ）に適用できるようにした転落防止用ガード体を提供することを目的としてなされたものである。   Therefore, the invention of the present application is lightweight and inexpensive as a device (guard body) having a function of preventing falling to the open portion side in a place where the outside of the road side portion is opened in a stepped down state (including side grooves). A tumbler that can be manufactured and can easily alert pedestrians, automobile / bicycle drivers, etc. that there are dangerous places, and can be applied to a wide range of places (side gutter size) with a single size. The object is to provide a guard body for prevention.

本願発明は、上記課題を解決するための手段として次の構成を有している。尚、本願発明は、道路の側部の外側が段下げ状態で開放されている場所に設置される転落防止用ガード体を対象にしている。又、以下の説明では、本願の転落防止用ガード体を単にガード体と表現することがある。   The present invention has the following configuration as means for solving the above problems. The present invention is directed to a fall-preventing guard body that is installed in a place where the outside of the side portion of the road is opened in a step-down state. Moreover, in the following description, the fall prevention guard body of the present application may be simply expressed as a guard body.

ところで、本願で表現している「道路の側部の外側が段下げ状態で開放されている場所」とは、道路側部に設けられた側溝内の水路や道路側部の外側に段下げ状態で隣接する開放部（下に例えば田畑がある）等のことで、道路側部から開放部側に人（自転車運転者を含む）や自動車が転落する危険がある場所のことである。   By the way, “the place where the outside of the side part of the road is opened in a lowered state” expressed in the present application is a state where the step is lowered outside the water channel in the side groove provided on the road side part or the side part of the road. It is a place where there is a risk that a person (including a bicycle driver) or a car may fall from the road side to the open part due to the adjacent open part (for example, there is a field below).

「本願請求項１の発明」
そして、本願請求項１のガード体（転落防止用ガード体）は、次の各構成を有したものである。 “Invention of Claim 1 of the Present Application”
And the guard body (guard body for fall prevention) of Claim 1 of this application has the following each structure.

即ち、本願請求項１のガード体は、細線材又は細棒材で格子状又は網目状に形成した面状メッシュ体と、該面状メッシュ体を道路側部の上端付近に支持するための複数組の支持材とで構成されている。   That is, the guard body according to claim 1 of the present invention includes a planar mesh body formed in a lattice shape or a mesh shape with a fine wire material or a thin rod material, and a plurality of support members for supporting the planar mesh body near the upper end of the road side portion. It consists of a set of support materials.

上記面状メッシュ体は、道路長さ方向から見て上面側が凸型となるアーチ状又は山形状に成形されている。面状メッシュ体の上面側に成形した凸型部分（アーチ状又は山形状部分）は、ガード体（面状メッシュ体）の上に人が乗りにくくしたり、通行人や自動車（又は自転車）の運転者にガード体が設置されていることを容易に認知させるためのものである。そして、面状メッシュ体の上記凸型部分の高さは、特に限定するものではないが面状メッシュ体の最下端部（幅方向両端部）より１０〜１５cm程度に設定することができる。尚、面状メッシュ体の凸型部分の高さを１０〜１５cm程度に設定すると、道路を通行する自動車の車体が当該凸型部分の上に被さっても、該車体下面がガード体に接触することがない。   The said planar mesh body is shape | molded by the arch shape or mountain shape from which the upper surface side becomes convex shape seeing from a road length direction. The convex part (arch-shaped or mountain-shaped part) molded on the upper surface side of the planar mesh body makes it difficult for people to ride on the guard body (planar mesh body) or for passers-by or automobiles (or bicycles). This is to make the driver easily recognize that the guard body is installed. And although the height of the said convex-shaped part of a planar mesh body is not specifically limited, it can be set to about 10-15 cm from the lowest end part (width direction both ends) of a planar mesh body. If the height of the convex portion of the planar mesh body is set to about 10 to 15 cm, the lower surface of the vehicle body comes into contact with the guard body even if the vehicle body of the automobile traveling on the road covers the convex portion. There is nothing.

上記各支持材は、道路側部の縦壁に固定される取付部と該取付部を縦壁に取付けた状態で道路側部外方の開放部に向けて延出し且つ面状メッシュ体の全幅を載置し得る長さを有した載置部とを設けたものである。尚、支持材における取付部と載置部とは、Ｌ形（直角）に連続するものでもよいが角度１００゜程度開いた状態で連続させたものでもよい。   Each of the support members includes an attachment portion fixed to the vertical wall of the road side, and the full width of the planar mesh body extending toward the open portion outside the road side portion with the attachment portion attached to the vertical wall. And a placement portion having a length capable of placing the. The mounting portion and the mounting portion in the support material may be continuous in an L shape (right angle) or may be continuous in an open state of about 100 °.

本願請求項１のガード体では、１つの面状メッシュ体を支持するのに複数組の支持材を使用するが、この支持材は面状メッシュ体の長さ方向の各端部寄り位置をそれぞれ支持する最低２組は必要である。尚、単一の面状メッシュ体の長さが長いものであれば、単一の面状メッシュ体につきその長さ方向に間隔をもって３〜４箇所をそれぞれ支持材で支持するようにしてもよい。   In the guard body of claim 1 of the present application, a plurality of sets of support materials are used to support one planar mesh body, and each of the support materials has a position closer to each end in the length direction of the planar mesh body. A minimum of two pairs to support are required. In addition, as long as the length of a single planar mesh body is long, you may make it support 3-4 places with a support material at intervals in the length direction about a single planar mesh body.

このガード体は、道路側部から開放側にはみ出して設置されるものであるが、このガード体の道路側部からの出幅は概ね面状メッシュ体の幅で決まる。面状メッシュ体の幅は３０cm程度（側溝の最小水路幅程度）のものでよいが、必要に応じて支持材の載置部を長くし（例えば６０cm程度の長さ）、その上に面状メッシュ体を２列に並置して、ガード体の出幅を例えば６０cm程度まで広げてもよい。   The guard body protrudes from the road side to the open side, and the width of the guard body protruding from the road side is generally determined by the width of the planar mesh body. The width of the planar mesh body may be about 30 cm (about the minimum water channel width of the side groove), but if necessary, the support material mounting portion is lengthened (for example, about 60 cm in length), and the planar shape is formed thereon. The mesh bodies may be juxtaposed in two rows, and the protruding width of the guard body may be increased to, for example, about 60 cm.

本願請求項１のガード体は、道路側部の設置場所に次のように取付けられる。まず、ガード体設置場所（道路側部の縦壁）に、１つの面状メッシュ体を支持するのに必要な個数（例えば２〜３個）の支持材を所定間隔をもって取付けるが、そのとき各支持材の取付部（縦向き）の上端部がそれぞれ道路の上面とほぼ同高さに揃うようにセットする。尚、各取付部を道路側部の縦壁に取付けるには、該取付部を例えばボルト止めによって行うことができる。各支持材の取付状態では、それぞれ載置部が道路側部から開放側に向けて延出している。次に、各支持材のそれぞれの載置部の上に面状メッシュ体を載せて、該面状メッシュ体の幅方向両端部にある細線材（又は細棒材）を各支持材の載置部に適宜の止め具で固定すると、１つのガード体の設置作業は完了する。そして、同様に、道路側部の必要長さ部分に各ガード体を隙間なしに連続設置していくことで、道路側部の外側近傍位置（開放部）に連続ガード体を完成させることができる。   The guard body of Claim 1 of this application is attached as follows to the installation place of a road side part. First, the number of supporting members (for example, 2 to 3) necessary to support one planar mesh body are attached to the guard body installation location (vertical wall on the side of the road) at predetermined intervals. Set so that the upper end of the mounting part (longitudinal direction) of the support material is almost flush with the upper surface of the road. In addition, in order to attach each attachment part to the vertical wall of a road side part, this attachment part can be performed by bolting, for example. In the attached state of each support member, the placement portion extends from the road side portion toward the open side. Next, a planar mesh body is placed on each placement portion of each support material, and the thin wire material (or thin rod material) at both ends in the width direction of the planar mesh body is placed on each support material. If it fixes to a part with a suitable stopper, the installation operation | work of one guard body will be completed. Similarly, by continuously installing each guard body in the necessary length portion of the road side portion without a gap, a continuous guard body can be completed at a position near the outside (open portion) of the road side portion. .

このように、道路側部の外側近傍位置（開放部）に本願請求項１のガード体を設置したものでは、道路側部における道路上面よりやや高い位置に面状メッシュ体の凸型部分が連続状態で見えるので、ガード体があることを歩行者等に容易に認知させることができる。又、面状メッシュ体の凸型部分は、その上に人が乗りにくい形状となっている。   As described above, in the case where the guard body according to claim 1 is installed at the position near the outside of the road side portion (open portion), the convex portion of the planar mesh body continues at a position slightly higher than the road upper surface on the road side portion. Since it can be seen in a state, a pedestrian or the like can easily recognize that there is a guard body. Further, the convex portion of the planar mesh body has a shape that makes it difficult for a person to ride on the convex portion.

ところで、道路側部に設けられる側溝の水路幅は、場所によって異なるが（例えば３０cm〜１００cmの範囲で７〜８種類ある）、本願請求項１のガード体は、道路側部の縦壁に対して片持ち式に取付け得る構造であるので、単一幅のガード体で側溝の水路幅に拘わりなくいずれのサイズの側溝にも適用できる。   By the way, although the channel width of the gutter provided in the road side portion differs depending on the location (for example, there are 7 to 8 types within the range of 30 cm to 100 cm), the guard body of claim 1 of the present application is against the vertical wall of the road side portion. Since it is a structure that can be attached in a cantilevered manner, it can be applied to a side groove of any size regardless of the channel width of the side groove with a single-width guard body.

「本願請求項２の発明」
本願請求項２の発明は、上記請求項１のガード体において、各支持材として載置部の基端部を取付部の上端部にヒンジで枢支したものを採用して、載置部上に支持した面状メッシュ体が横向きの使用位置から上方に弧回動開放できるようにしたものである。 “Invention of Claim 2 of the Present Application”
The invention of claim 2 of the present application employs a guard body according to claim 1 in which the base end portion of the mounting portion is pivotally supported by the upper end portion of the mounting portion as a support member on the mounting portion. The planar mesh body supported on the upper side can be arc-turned and opened upward from the lateral use position.

この請求項２のガード体では、各支持材の取付部を側溝の縦壁（道路側縦壁）に固定した状態で、各ヒンジを中心にして面状メッシュ体を各支持材の載置部とともに横向きの使用位置と上方の開放位置との間で上下に弧回動させることができる。   In the guard body according to claim 2, the planar mesh body is placed around the hinges with the mounting portions of the support members fixed to the vertical walls (road side vertical walls) of the side grooves. At the same time, the arc can be turned up and down between the lateral use position and the upper open position.

「本願請求項１の発明の効果」
本願請求項１の発明のガード体（転落防止用ガード体）は、次のような効果を有している。 “Effect of the invention of claim 1 of the present application”
The guard body (falling prevention guard body) according to the first aspect of the present invention has the following effects.

(１) 複数組の支持材で面状メッシュ体を道路側部の縦壁に片持ち状態で取付け得るように構成されているので、単一形状（幅）のガード体であっても水路幅が異なる多種類の側溝に対していずれも支障なく転落防止用として適用できる。従って、水路幅が異なる多種類の側溝に対しても、単一形状（幅）のガード体を製作しておけばよいので、ガード体を水路幅に応じて多品種製作する場合に比して繁雑さや製作コストやストックコスト等を大幅に軽減できる。   (1) Since the planar mesh body can be attached to the vertical wall on the side of the road in a cantilevered manner with a plurality of sets of support materials, the width of the channel can be achieved even with a single-shaped (width) guard body. Any of the various types of side grooves with different values can be applied to prevent falling without any trouble. Therefore, it is only necessary to produce a single-shaped (width) guard body for many types of side grooves with different channel widths, compared to the case of producing a variety of guard bodies according to the channel width. The complexity, production cost and stock cost can be greatly reduced.

(２) このガード体を道路側部の縦壁に設置していると、道路側部を通行する人（又は自転車搭乗者）が誤って転落の危険がある開放部側に移動しても、該人（又は自転車）がガード体で受け止められるので、危険側への転落を防止できる。   (2) If this guard body is installed on the vertical wall of the road side, even if a person (or a bicycle occupant) passing by the road side accidentally moves to the open side where there is a risk of falling, Since the person (or bicycle) is received by the guard body, it is possible to prevent the person from falling to the dangerous side.

(３) 面状メッシュ体の上面側を凸型となるアーチ状又は山形状に成形していると、平面状態のものより道路側を通行する人（及び自転車や自動車の運転者）からよく見えるので、通行人（及び運転者）に対して注意力を喚起させる（危険場所であることを知らしめる）のに役立つとともに、上面側が凸型であると面状メッシュ体の上に人が乗りにくくなるので、危険側開放部への転落防止機能が一層向上する。   (3) When the upper surface side of the planar mesh body is formed into a convex arch shape or mountain shape, it can be seen better by people (and bicycle and car drivers) who pass on the road side than those in the flat state. Therefore, it is useful for alerting passersby (and drivers) (informing them that it is a dangerous place), and if the top side is convex, it is difficult for people to ride on the planar mesh body. Therefore, the fall prevention function to the dangerous side opening part is further improved.

(４) 複数組の支持材と面状メッシュ体（格子状又は網目状）とで構成しているので、危険側開放部への転落防止機能を確保しつつ軽量且つ安価に製作できる。   (4) Since it is composed of a plurality of sets of support materials and planar mesh bodies (lattice or mesh-like), it can be manufactured at a low cost while ensuring the function of preventing falling to the dangerous side opening.

［図１〜図６の第１実施例］
この第１実施例のガード体１は、図１に示すように、それぞれ細線材（細棒材でも可）からなる横線材２１，２１・・と縦線材２２，２２・・とを格子状（網目状でも可）に組付けて形成した面状メッシュ体２と、該面状メッシュ体２を道路４の側部４１（例えばＵ型の側溝５の側壁５２）の上端付近に支持するための複数組の支持材３とで構成されている。 [First Embodiment of FIGS. 1 to 6]
As shown in FIG. 1, the guard body 1 according to the first embodiment has a horizontal wire 21, 21... And a vertical wire 22, 22. A planar mesh body 2 formed by assembling in a mesh shape, and for supporting the planar mesh body 2 near the upper end of the side portion 41 of the road 4 (for example, the side wall 52 of the U-shaped side groove 5). It comprises a plurality of sets of support materials 3.

面状メッシュ体２に使用されている横線材２１及び縦線材２２は、適宜太さ（例えば２〜５mm程度の太さ）の細線材又は細棒材を使用している。尚、図１及び図２の表示では縦横の各線材２１，２２をそれぞれ１本の線で表しているが、該各線材２１，２２は、実際には図４及び図５に示すように適宜の太さを有していて、荷重をかけてもほとんど撓まない剛性を有したものである。   As the horizontal wire 21 and the vertical wire 22 used in the planar mesh body 2, a thin wire or a thin rod having an appropriate thickness (for example, a thickness of about 2 to 5 mm) is used. 1 and 2, the vertical and horizontal wires 21 and 22 are each represented by a single line. However, the wires 21 and 22 are actually appropriate as shown in FIGS. It has a thickness of 2 mm, and has rigidity that hardly bends even when a load is applied.

図１に示す第１実施例の面状メッシュ体２では、その大きさとして、特に限定するものではないが長さＬが１００cm、幅Ｍが３０cm程度に設定できる。又、この格子状の面状メッシュ体２は、１つ当たりの空間部の大きさとして子供の足裏が入り込まない程度まで小さくすることが望ましい。例えば、横線材２１，２１間の間隔を５〜６cm程度にしておくと、誤って子供がこのガード体（面状メッシュ体２）の上に乗っても足がメッシュ体の空間部内に入り込むことがない。   In the planar mesh body 2 of the first embodiment shown in FIG. 1, the size is not particularly limited, but the length L can be set to about 100 cm and the width M can be set to about 30 cm. Further, it is desirable that the lattice-like planar mesh body 2 is made small to the extent that the sole of the child does not enter as the size of each space portion. For example, if the distance between the horizontal wires 21 and 21 is set to about 5 to 6 cm, even if a child accidentally rides on the guard body (planar mesh body 2), the foot enters the space of the mesh body. There is no.

面状メッシュ体２は、その長さ方向から見て上面側が凸型となるアーチ状に成形されている。そして、この面状メッシュ体２における最低部（幅方向各端部の縦線材２２の位置）からアーチ頂部までの高さＮは、１０〜１５cm程度に設定している。   The planar mesh body 2 is formed in an arch shape in which the upper surface side is convex when viewed from the length direction. And the height N from the lowest part (position of the vertical wire 22 at each end in the width direction) to the top of the arch in the planar mesh body 2 is set to about 10 to 15 cm.

各支持材３には、この実施例では曲げ応力に強いＬ型アングル材が使用されている。尚、この支持材３としては、金属製のパイプ材（丸パイプでも角パイプでも可）を使用してもよい。   In this embodiment, an L-shaped angle material that is strong against bending stress is used for each support material 3. As the support material 3, a metal pipe material (either a round pipe or a square pipe) may be used.

この第１実施例のガード体１で使用される支持材３は、１つの面状メッシュ体２に対してその長さ方向の両端部付近と中間部の３箇所を支持するために３組使用しているが、他の実施例では、面状メッシュ体２の長さ方向の両端部付近を支持する２組だけでもよいし、さらに該面状メッシュ体２が長いものでは１つの面状メッシュ体２に対して４組以上の支持材３を使用してもよい。   Three sets of support members 3 used in the guard body 1 of the first embodiment are used to support three portions in the vicinity of both end portions and the intermediate portion in the length direction with respect to one planar mesh body 2. However, in other embodiments, only two sets that support the vicinity of both end portions in the length direction of the planar mesh body 2 may be used, and if the planar mesh body 2 is long, one planar mesh is used. Four or more sets of support members 3 may be used for the body 2.

この第１実施例で使用している各支持材３，３，３は、上下向きの取付部３１の上端部に横向きに延出する載置部３２を一体に連続させたもので、全体として略Ｌ型の形状を呈するものである。この第１実施例で使用される支持材３では、載置部３２と取付部３１間の角度を１００°程度に設定していて、図２及び図４に示すように支持材３の取付部３１を鉛直な縦壁５２に取付けた状態では、載置部３２が水平姿勢より角度１０°程度外側に上り傾斜するようにしている。   Each support material 3, 3 and 3 used in the first embodiment is obtained by integrally placing a mounting portion 32 extending laterally on the upper end portion of the vertically mounting portion 31 as a whole. It exhibits a substantially L-shaped shape. In the support member 3 used in the first embodiment, the angle between the mounting portion 32 and the attachment portion 31 is set to about 100 °, and the attachment portion of the support member 3 as shown in FIGS. In a state where 31 is attached to the vertical vertical wall 52, the mounting portion 32 is inclined upward by about 10 ° from the horizontal posture.

各支持材３の取付部３１は、図２又は図４に示すように道路側部４１に設置された側溝５の側壁（特許請求の範囲中の縦壁に相当する）５２に固定材（ボルト）１１，１１で固定されるものである。尚、取付部３１の側壁５２への固定方法は、上記ボルト１１による固定に代えて適宜の方法を採用できる。   As shown in FIG. 2 or 4, the attachment portion 31 of each support member 3 is fixed to a side wall (corresponding to a vertical wall in the claims) 52 of the side groove 5 installed in the road side portion 41. ) 11 and 11 are fixed. In addition, the fixing method to the side wall 52 of the attaching part 31 can employ | adopt an appropriate method instead of fixing with the said volt | bolt 11. FIG.

他方、各支持材３の載置部３２は、その上に面状メッシュ体２の全幅Ｍを載せ得る長さ（３０cm強の長さ）を有している。   On the other hand, the placement portion 32 of each support material 3 has a length (a length of slightly over 30 cm) on which the entire width M of the planar mesh body 2 can be placed.

そして、この第１実施例のガード体１は、図２〜図４に示すように道路側部４１に設けた側溝５の道路側側壁５２の内面に次のように設置される。尚、図２〜図４のガード体設置例では、側溝５の水路幅Ｗとして７０cm程度のものを採用している一方、ガード体１の面状メッシュ体２の幅Ｍが３０cm程度のもを採用している。   And the guard body 1 of this 1st Example is installed as follows in the inner surface of the road side side wall 52 of the side groove 5 provided in the road side part 41, as shown in FIGS. In addition, in the example of guard body installation of FIGS. 2-4, while the water channel width W of the side groove 5 is about 70 cm, the width M of the planar mesh body 2 of the guard body 1 is about 30 cm. Adopted.

まず、図２及び図４に示すように、ガード体設置場所（道路側部４１の側溝５の道路側側壁５２の内面）に、１つの面状メッシュ体２を支持するのに必要な個数（図示例では３個）の支持材３，３，３を所定間隔をもって取付けるが、そのとき各支持材３の取付部３１の上端部（載置部３２との角部）がそれぞれ道路４の上面とほぼ同高さに揃うようにセットした状態で、各取付部３１をボルト１１で側壁５２の内面に固定する。尚、この各支持材３，３，３の取付状態では、それぞれ載置部３２，３２，３２が側溝５の水路側（開放部５１側）に向けて水平姿勢から角度１０°程度上向き姿勢で延出している。   First, as shown in FIGS. 2 and 4, the number necessary to support one planar mesh body 2 at the guard body installation location (the inner surface of the road side wall 52 of the side groove 5 of the road side portion 41) ( In the illustrated example, three support members 3, 3 and 3 are attached at a predetermined interval. At that time, the upper end portions (corner portions with the mounting portions 32) of the attachment portions 31 of the support members 3 are respectively the upper surfaces of the roads 4. The mounting portions 31 are fixed to the inner surface of the side wall 52 with the bolts 11 in a state where they are set so as to be substantially flush with each other. In addition, in the mounting state of the support members 3, 3, and 3, the mounting portions 32, 32, and 32 are in an upward posture of about 10 ° from the horizontal posture toward the water channel side (opening portion 51 side) of the side groove 5. It is extended.

次に、各支持材３，３，３のそれぞれの載置部３２，３２，３２の上に面状メッシュ体２を載せ、該面状メッシュ体２の幅方向両端部にある各縦線材２２，２２を各載置部３２，３２，３２にそれぞれ止め具１２（逆Ｕ型の止めボルト）で固定すると、１つのガード体１の設置作業は完了する。   Next, the planar mesh body 2 is placed on the mounting portions 32, 32, 32 of the support members 3, 3, 3, and the vertical wire members 22 at both ends in the width direction of the planar mesh body 2. , 22 are fixed to the mounting portions 32, 32, 32 with the stoppers 12 (reverse U-shaped set bolts), and the installation work of one guard body 1 is completed.

そして、同様に、側溝５の必要長さ部分に各ガード体１，１・・を隙間なしに連続設置していくことで、図３に示すように側溝５の道路側側壁５２の内面側（上方開放部５１）に連続ガード体を完成させる。   Similarly, by continuously installing the guard bodies 1, 1... In the necessary length portion of the side groove 5 without a gap, the inner surface side of the road side wall 52 of the side groove 5 as shown in FIG. A continuous guard body is completed in the upper opening 51).

この第１実施例のガード体１は、次のような有効な機能を有している。   The guard body 1 of the first embodiment has the following effective functions.

第１に、このガード体１は、複数組（３組）の支持材３，３，３で面状メッシュ体２を道路側部４１の側溝５の側壁５２に片持ち状態で取付け得るように構成されているので、単一形状（幅）のガード体１であっても水路幅Ｗが異なる多種類の側溝５に対して支障なく適用できる。即ち、水路幅Ｗが異なる多種類の側溝５に対しても、単一形状（幅）のガード体１を製作しておけばよいので、ガード体１を水路幅に応じて多品種製作する場合に比して繁雑さや製作コストやストックコスト等を大幅に軽減できる。   First, the guard body 1 can be mounted in a cantilever manner on the side wall 52 of the side groove 5 of the road side portion 41 with a plurality of sets (three sets) of support members 3, 3, 3. Since it is comprised, even if it is the guard body 1 of a single shape (width | variety), it can apply without trouble with respect to the many types of side groove 5 from which the channel width W differs. That is, the guard body 1 having a single shape (width) may be manufactured for various types of side grooves 5 having different channel widths W. Therefore, when the guard body 1 is manufactured in various types according to the channel width. Compared to the above, the complexity, production cost, stock cost, etc. can be greatly reduced.

第２に、図３及び図４に示すガード体設置状態では、面状メッシュ体２が側溝５の道路側側壁５２の上面と同高さ位置から内方側（上方開放部５１）に向けて幅Ｍ（３０cm程度）だけ被さっている。従って、道路側部４１を通行する人（又は自転車搭乗者）が誤って転落の危険がある水路側に移動しても、該人（又は自転車）がガード体１で受け止められる（危険側への転落を防止できる）。   2ndly, in the guard body installation state shown in FIG.3 and FIG.4, the planar mesh body 2 faces inward (upper open part 51) from the same height position as the upper surface of the road side wall 52 of the side groove | channel 5. FIG. It covers only width M (about 30cm). Therefore, even if a person (or a bicycle occupant) passing through the road side portion 41 accidentally moves to the waterway side where there is a risk of falling, the person (or bicycle) is received by the guard body 1 (to the dangerous side). Can prevent falling).

第３に、面状メッシュ体２の上面側を凸型となるアーチ状に成形していると、平面状態のものより道路４側を通行する人（及び自転車や自動車の搭乗者）からよく見えるので、通行人に対して注意力を喚起させる（危険場所であることを知らしめる）のに役立つとともに、上面側が凸型であると面状メッシュ体２の上に人が乗りにくくなるので、側溝５内への転落防止機能が一層向上する。   Thirdly, when the upper surface side of the planar mesh body 2 is formed into a convex arch shape, it can be seen well by a person (and a passenger of a bicycle or a car) who passes on the road 4 side from the planar state. Therefore, it is useful for alerting the passerby (notifying that it is a dangerous place), and if the upper surface side is convex, it is difficult for a person to get on the planar mesh body 2, so the side groove The function of preventing falling into 5 is further improved.

第４に、ガード体１は、複数組の支持材３と面状メッシュ体２で構成しているので、危険側開放部への転落防止機能を確保しつつ軽量且つ安価に製作できる。   Fourthly, since the guard body 1 is composed of a plurality of sets of the support material 3 and the planar mesh body 2, it can be manufactured at a low cost and with low cost while ensuring the function of preventing falling to the dangerous side opening.

第５に、ガード体１は設置状態で側溝５の側壁５２から開放部５側に横向きに延出するので、道路側部にフェンスやガードレールを立設した場合のように、道路４の有効幅が実質的に狭くならず、しかも自動車や人が通行時に道路幅が狭く感じない（圧迫感がなくなる）。   Fifth, since the guard body 1 extends laterally from the side wall 52 of the side groove 5 to the open portion 5 side in the installed state, the effective width of the road 4 is increased as in the case where a fence or a guard rail is erected on the side of the road. However, the road width does not feel narrow when a car or a person passes (the feeling of pressure disappears).

第６に、ガード体１の設置状態では、図５に示すように面状メッシュ体２の凸型部分の路面からの高さＮが比較的低い（Ｎ＝１０cm〜１５cm程度）ので、路上を通行する自動車の車体Ｃ部分（例えば道路のコーナー部分では自動車のフロント部分が道路側部４１からはみ出ることがある）がガード体１の上に被さっても、該車体Ｃの下面Ｃａがガード体１に接触することがない（路面から車体下面Ｃａまでの高さＨが２０cm以上ある）。   Sixth, in the installed state of the guard body 1, the height N from the road surface of the convex portion of the planar mesh body 2 is relatively low (N = about 10 cm to 15 cm) as shown in FIG. Even if a vehicle body C portion of a passing vehicle (for example, the front portion of the vehicle may protrude from the road side portion 41 at a corner portion of a road) covers the guard body 1, the lower surface Ca of the vehicle body C remains on the guard body 1. (Height H from the road surface to the lower surface Ca of the vehicle body is 20 cm or more).

図６には、図１（第１実施例）のガード体１の他の設置例を示しているが、この図６のガード体設置例では、道路側部４１の縦壁５２の外側に田畑のような開放部５１がある場所にガード体１を設置したものである。尚、この図６におけるガード体１は、図１のものと同じである。   FIG. 6 shows another installation example of the guard body 1 of FIG. 1 (first embodiment). In this guard body installation example of FIG. 6, the field is located outside the vertical wall 52 of the road side portion 41. The guard body 1 is installed in a place where there is an open part 51 as shown in FIG. The guard body 1 in FIG. 6 is the same as that in FIG.

［図７の第２実施例］
図７に示す第２実施例のガード体１は、上記第１実施例のガード体の変形例として、支持材３として取付部３１と載置部３２とを直角に連続させたものを使用している。従って、この図７（第２実施例）のガード体１の設置状態では、支持材３の載置部３２が水平方向に延出するので、その上部に支持される面状メッシュ体２は水平姿勢で幅中央部が上方に凸型形状となる。尚、この第２実施例におけるその他の構成は、上記第１実施例のものと同じである。 [Second Example of FIG. 7]
The guard body 1 according to the second embodiment shown in FIG. 7 is a modification of the guard body according to the first embodiment, in which a support member 3 in which an attachment portion 31 and a placement portion 32 are continuous at a right angle is used. ing. Accordingly, in the installed state of the guard body 1 in FIG. 7 (second embodiment), the placement portion 32 of the support member 3 extends in the horizontal direction, and therefore the planar mesh body 2 supported on the upper portion thereof is horizontal. In the posture, the central portion of the width has a convex shape upward. The other configurations in the second embodiment are the same as those in the first embodiment.

［図８〜図９の第３実施例］
この図８〜図９に示す第３実施例のガード体１は、本願の請求項２に対応するものであって、設置状態において、支持材３の載置部３２とともに面状メッシュ体２を上方に弧回動開放させ得るようにしたものである。 [Third Example of FIGS. 8 to 9]
The guard body 1 of the third embodiment shown in FIGS. 8 to 9 corresponds to claim 2 of the present application. In the installed state, the guard body 1 together with the mounting portion 32 of the support member 3 is provided. The arc can be pivoted open upward.

即ち、図８〜図９（第３実施例）に示すガード体１は、各支持材３（３組ある）として、載置部３２の基端部３２ａを取付部３１の上端部３１ａにヒンジ３５で枢支したものを採用しており、載置部３２と面状メッシュ体２とが実線図示する横向きの使用位置から鎖線図示（符号３２′、２′）するように上方に弧回動開放できるようにしている。   That is, in the guard body 1 shown in FIGS. 8 to 9 (third embodiment), the base end portion 32a of the mounting portion 32 is hinged to the upper end portion 31a of the mounting portion 31 as each supporting member 3 (there are three sets). 35 is used, and the mounting portion 32 and the planar mesh body 2 are arc-turned upward so as to show a chain line (reference numerals 32 ', 2') from a lateral use position shown by a solid line. It can be opened.

この第３実施例では、ガード体１の設置状態において面状メッシュ体２を実線図示する使用位置で姿勢維持させるのに、図９に拡大図示するように、載置部３２の基端部３２ａと取付部３１の上端部３１ａにそれぞれ傾斜面３２ｂ，３１ｂを設けて、面状メッシュ体２が横向き使用姿勢にある状態で該両傾斜面３２ｂ，３１ｂ同士が衝合して、載置部３２がそれ以上、下方に弧回動しないようにしている。尚、面状メッシュ体２の横向き使用姿勢において、載置部３２がそれ以上、下方に弧回動しないようにするためのストッパー手段としては、上記傾斜面３２ｂ，３１ｂ同士の衝合形態に代えて（あるいはそれに加えて）圧縮強度のある斜め支え材を取付部３１と載置部３２間に介在させてもよい。   In this third embodiment, in order to maintain the posture of the planar mesh body 2 at the use position shown by the solid line in the installed state of the guard body 1, as shown in an enlarged view in FIG. And the upper end portion 31a of the mounting portion 31 are provided with inclined surfaces 32b and 31b, respectively, and the inclined surfaces 32b and 31b collide with each other in a state where the planar mesh body 2 is in the lateral use posture. However, the arc does not rotate downward any further. In addition, in the horizontal use posture of the planar mesh body 2, as a stopper means for preventing the mounting portion 32 from further arcing downward, the above-described contact form between the inclined surfaces 32b and 31b is used. (Or in addition), an oblique support member having compressive strength may be interposed between the mounting portion 31 and the mounting portion 32.

そして、図８〜図９に示す第３実施例のガード体１では、実線図示するガード体使用姿勢から、面状メッシュ体２の延出側を手で上方に持ち上げると、ヒンジ３５部分を中心にして面状メッシュ体２を各載置部３２とともに鎖線図示（符号２′，３２′）するように上方に弧回動開放させることができる。   And in the guard body 1 of 3rd Example shown in FIGS. 8-9, if the extension side of the planar mesh body 2 is lifted upwards by hand from the guard body use attitude | position shown as a continuous line, it will center on hinge 35 part. Thus, the planar mesh body 2 can be pivoted and opened upward so as to be shown with chain lines (reference numerals 2 'and 32') together with the respective mounting portions 32.

従って、この第３実施例（図８〜図９）のガード体１を道路側部４１に設けた側溝５の上部開放部５１のガード用として使用したものでは、該側溝５内の水路を清掃するときにガード体１の面状メッシュ体２（及び載置部３２）を上方に弧回動開放させておくことで、該水路内の清掃作業が容易に行える。又、このガード体１では、上下弧回動部分（面状メッシュ体２と支持材の載置部３２）が軽量であるので、面状メッシュ体２の開閉操作が軽作業で行える。   Accordingly, in the case where the guard body 1 of the third embodiment (FIGS. 8 to 9) is used as a guard for the upper open portion 51 of the side groove 5 provided on the road side portion 41, the water channel in the side groove 5 is cleaned. In doing so, the planar mesh body 2 (and the mounting portion 32) of the guard body 1 is opened in an arc-turned upward direction, so that the cleaning operation in the water channel can be easily performed. Moreover, in this guard body 1, since the up-and-down arc rotation part (planar mesh body 2 and the support material mounting portion 32) is lightweight, the opening and closing operation of the planar mesh body 2 can be performed with a light work.

［図１０の第４実施例］
図１０の第４実施例のガード体１は、上記第３実施例（図８〜図９）の変形例を示すものであって、道路側部４１の設けられた側溝５の水路幅Ｗ（Ｗ＝７０cm程度）の大部分を被覆し得るようにしたものである。 [Fourth embodiment of FIG. 10]
