Description

本発明は、道路等の側溝や排水桝（以下、単に側溝等という）に装着されるグレーチングの跳ね上がりを確実に防止することができるグレーチングの固定金具に関する。 The present invention relates to a fixing bracket for a grating that can reliably prevent jumping of a grating attached to a side groove or a drainage pit (hereinafter simply referred to as a side groove) on a road or the like.

側溝等に装着される溝蓋として、排水機能を損なわないようにするためにグレーチングが多用されている。こうした溝蓋用のグレーチングは一般に鋼製で、平鋼よりなる主部材と、並設される主部材の両端に固定されるエンドプレートと、主部材に直交して固定されるスクリューバー等のクロスバーとからなり、多くの場合、側溝に固着の受枠に装着される。 Grating is often used as a groove lid mounted on a side groove or the like so as not to impair the drainage function. The grating for the groove cover is generally made of steel, a main member made of flat steel, an end plate fixed to both ends of the main member arranged in parallel, and a cross such as a screw bar fixed orthogonally to the main member. It consists of a bar and is often mounted on a receiving frame fixed to the side groove.

側溝等に装着されたグレーチングは、車両等の走行によりガタ付き、まれにではあるが、跳ね上がって車両に当たる事故を発生することがある。こうした問題を解消するため、グレーチングを固定する手段がいくつか提案されている。グレーチングを押える押え金具と受け枠の当て金をボルトにより連結してグレーチングを固定するもの（特許文献１）、グレーチング下面に垂直に固定される管にバネと共にロッドを装着し、ドライバー等の工具を用いてロッドを一方向に回動させることによりロッドより側方に突出する鉤部材を受枠に固着の収納部に収めてロックする一方、ドライバー等の工具を用いてロッドをバネの作用に抗して押込みながら逆方向に回動させることにより鉤部材を収納部より離脱させてロックを解除させるようにしたもの（特許文献２）などがその例である。
特開２０００−８０７１４号実用新案登録第３０９９２５１号 Grating attached to a side groove or the like may be rattled by traveling of the vehicle or the like, and in rare cases, may cause an accident that jumps up and hits the vehicle. In order to solve these problems, several means for fixing the grating have been proposed. Fixing the grating by connecting the holding bracket that holds the grating and the metal pad of the receiving frame with a bolt (Patent Document 1), attaching a rod together with a spring to a pipe that is fixed vertically to the lower surface of the grating, By rotating the rod in one direction, the rod member protruding from the side of the rod is locked in the receiving part fixed to the receiving frame, while the tool is used to resist the spring action using a tool such as a screwdriver. An example is one in which the hook member is released from the storage portion by being rotated in the opposite direction while being pushed and the lock is released (Patent Document 2).
JP 2000-80714 A Utility model registration No. 3099251

特許文献１に開示されるようなグレーチングの固定方式では、側溝等の清掃などでグレーチングを取外す際、ボルトを緩めてから、またグレーチングの取付けはボルトを捩じ込むことによって行わねばならず、グレーチングの着脱が面倒である。この点、特許文献２に開示される固定方式では、工具によるロッドの回動量が半回転程度ですみ、グレーチングの着脱が容易である。 In the fixing method of the grating as disclosed in Patent Document 1, when removing the grating by cleaning a side groove or the like, the bolt must be loosened, and the grating must be attached by screwing in the bolt. The attachment and detachment is troublesome. In this regard, in the fixing method disclosed in Patent Document 2, the amount of rotation of the rod by the tool is only about half rotation, and the grating can be easily attached and detached.

本発明は、作業が容易であり、しかも固定がより確実に行えるようなグレーチングの固定金具を提供することを目的とする。 An object of the present invention is to provide a grating fixing bracket which is easy to work and can be fixed more reliably.

請求項１に係る発明は、側溝等に直接又は側溝等に取着の受枠に装着されるグレーチングを側溝等又は受枠に着脱可能に固定するための固定金具であって、グレーチングに固定される筒状金具と、該金具に回動かつ軸方向にスライド可能に嵌挿され、一端が筒状金具より突出して前記側溝等又は受枠に形成の嵌合凹部又は嵌合孔（以下、単に嵌合孔等という）に嵌合可能なロッドと、前記筒状金具に装着されて前記ロッドをその一端が筒状金具より突出する方向に付勢するバネと、前記筒状金具に形成される第１及び第２の溝と、前記ロッドより径方向に突設され、前記第１の溝に移動可能に嵌挿されるピン及び前記第２の溝に移動可能に嵌挿されて突出する操作把手とよりなり、前記第１の溝は筒状金具の軸方向と直交する方向に形成されるコ字形の溝部と、該コ字形の溝部の一端からロッド一端側に向けて軸方向に形成される鉤溝を備え、前記ピンが前記バネの作用に抗してコ字形の溝部内を溝端まで後退すると、ロッド一端が受枠の嵌合孔より離脱するようになっており、また前記第２の溝は前記ピンが第１の溝に沿って移動するときの操作把手の動きを許容するように形成されることを特徴とする。 The invention according to claim 1 is a fixing bracket for removably fixing a grating attached to a receiving frame attached to a side groove or the like directly or to a side groove or the like to the side groove or the receiving frame, and a cylinder fixed to the grating. And a fitting recess or fitting hole (hereinafter simply referred to as a fitting hole) that is inserted into the fitting so as to be pivotable and slidable in the axial direction, with one end protruding from the cylindrical fitting and formed in the side groove or the receiving frame. Etc.), a spring mounted on the cylindrical fitting and biasing the rod in a direction in which one end protrudes from the cylindrical fitting, and a first and a second formed on the cylindrical fitting. A second groove, a pin projecting in a radial direction from the rod, movably inserted in the first groove, and an operation handle movably inserted in the second groove and projecting; The first groove is formed in a direction orthogonal to the axial direction of the cylindrical metal fitting. A U-shaped groove, and a groove formed in an axial direction from one end of the U-shaped groove toward one end of the rod, and the pin resists the action of the spring to the end of the U-shaped groove. When retracted, one end of the rod is detached from the fitting hole of the receiving frame, and the second groove allows the operation handle to move when the pin moves along the first groove. It is formed.

請求項２に係る発明は、請求項１に係る発明において、前記筒状金具はグレーチング内に横向きに固定され、前記ピンが第１の溝の鉤溝に位置するとき、前記操作把手は横ないし略横向きに倒れてグレーチングより突出しないようにしたことを特徴とする。 The invention according to claim 2 is the invention according to claim 1, wherein when the cylindrical metal fitting is fixed laterally in the grating and the pin is positioned in the ridge groove of the first groove, the operation handle is horizontal or horizontal. It is characterized in that it does not protrude from the grating by falling sideways.

請求項１に係る発明によると、グレーチングの固定はピンが第１の溝の鉤溝に嵌合し、ロッド一端が側溝等又は受枠の嵌合孔等に嵌合することによって行われる。固定状態からの解除は、操作把手を手又は工具を用いて掴んでバネの作用に抗し、軸方向に後退させてピンを鉤溝より離脱させ、ついで操作把手をピンがコ字形の溝部に沿って移動するように一定量回動させたのちばねの作用に抗して後退させ、更に逆向きに回動させることによって行われる。したがって固定状態から解除するにはピンはバネの作用に抗した鉤溝からの離脱→正方向への回動→バネの作用に抗した軸方向への移動→逆向きの回動と複雑な動きを行わねばならず、車両等の走行によって固定金具に振動が伝わったとしても、ピンが上記のような複雑な動きをしない限り、固定が解除されることはなく、固定がより確実に行われる。また固定時には操作把手を回動するだけで、ロッド一端の突出はバネの作用によって行われるため、固定作業が容易である。 According to the first aspect of the present invention, the fixing of the grating is performed by fitting the pin into the groove of the first groove and fitting one end of the rod into the side groove or the like or the fitting hole of the receiving frame. To release from the fixed state, grip the operation handle with a hand or a tool to resist the action of the spring, move it back in the axial direction to release the pin from the groove, and then move the operation handle to the groove where the pin is U-shaped. It is performed by rotating a certain amount so as to move along, then retracting against the action of the spring, and further rotating in the opposite direction. Therefore, to release from the fixed state, the pin is detached from the groove against the action of the spring → turns in the forward direction → moves in the axial direction against the action of the spring → turns in the reverse direction and complicated movement Even if vibrations are transmitted to the fixture due to running of the vehicle, etc., the pin will not be released unless the pin moves in a complicated manner as described above, and the fixation is performed more reliably. . Further, at the time of fixing, only the operation handle is rotated, and the protrusion of one end of the rod is performed by the action of the spring, so that the fixing work is easy.

請求項２に係る発明によると、筒状金具はグレーチング内に横向きに固定されるため、操作把手がグレーチングの表面近くにあって掴み易くなり、また固定状態ではグレーチングより突出しないため、車両等の走行に支障を与えたり、歩行者の走行時につまずいたりすることがない。 According to the second aspect of the present invention, since the cylindrical metal fitting is fixed laterally in the grating, the operation handle is close to the surface of the grating and is easy to grip, and does not protrude from the grating in the fixed state. It will not interfere with driving or trip over pedestrians.

以下、本発明の実施形態の固定金具について図面により説明する。
図１は、固定金具１を取付けたグレーチング２が排水桝の受枠３に装着された状態を示すもので、固定金具１は図２〜図４に示すように、フランジ管状の筒状金具５と、該金具５に回動かつ軸方向にスライド可能に嵌挿される円形断面のロッド６と、筒状金具５内に装着され、ロッド６を筒状金具５より突出する方向に付勢するバネ７とからなっている。 Hereinafter, a fixture according to an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 shows a state in which a grating 2 to which a fixing metal fitting 1 is attached is mounted on a drainage frame receiving frame 3. The fixing metal fitting 1 includes a flange-shaped tubular metal fitting 5 and a tubular metal fitting 5 as shown in FIGS. The rod 6 having a circular cross section that is inserted into the metal fitting 5 so as to be rotatable and slidable in the axial direction, and the spring 7 that is mounted in the cylindrical metal fitting 5 and biases the rod 6 in a direction protruding from the cylindrical metal fitting 5. It is made up of.

筒状金具５には軸心を挟んだ対向位置に第１の溝８と第２の溝９が形成され、第１の溝８は図２に示されるように筒状金具５の軸方向と直交する方向に形成されるコ字形の溝部８１と、該コ字形の溝部８１の一端からロッド一端側に向けて軸方向に形成される鉤溝８２からなっている。また第２の溝９は図３に示されるように、幅広の角溝９１と、該角溝９１の両端からロッド一端側に向けて軸方向に形成される鉤溝９２及び長溝９３よりなり、幅広の角溝９１と鉤溝９２よりなる第２の溝９は、第１の溝８が丁度納まるサイズをなし、後述するピン６２が第１の溝８内を移動するときに操作把手６３が前記第２の溝９内を動きうるようにして、その動きを許容できるようにしている。なお、上述する長溝９３は形成されていなくてもよい。 The cylindrical metal fitting 5 is formed with a first groove 8 and a second groove 9 at positions opposed to each other with the axis interposed therebetween, and the first groove 8 is arranged in the axial direction of the cylindrical metal fitting 5 as shown in FIG. A U-shaped groove portion 81 formed in an orthogonal direction and a ridge groove 82 formed in an axial direction from one end of the U-shaped groove portion 81 toward one end of the rod. Further, as shown in FIG. 3, the second groove 9 includes a wide square groove 91, a ridge groove 92 and a long groove 93 formed in the axial direction from both ends of the square groove 91 toward one end of the rod, The second groove 9 composed of the wide square groove 91 and the ridge groove 92 has a size that the first groove 8 just fits in, and the operation handle 63 is moved when the pin 62 described later moves in the first groove 8. The movement in the second groove 9 is enabled to allow the movement. The long groove 93 described above may not be formed.

ロッド６は、図４に示すように、一定の間隔を存して一対のフランジ６１と、該フランジ間において径方向に突出するピン６２及び小さな板状の操作把手６３を有し、一対のフランジ６１がガイドとなってロッド６は筒状金具５内を軸方向にスライドし、かつ回動できるようになっており、ピン６２は前記第１の溝８に遊嵌して該溝８に沿って移動し、また操作把手６３は第２の溝９に遊嵌し、鉤溝９２に遊嵌しうるようになっている。 As shown in FIG. 4, the rod 6 has a pair of flanges 61 with a constant interval, a pin 62 projecting radially between the flanges, and a small plate-like operation handle 63. Reference numeral 61 serves as a guide so that the rod 6 can slide and rotate in the axial direction in the cylindrical metal fitting 5, and the pin 62 is loosely fitted in the first groove 8 along the groove 8. The operation handle 63 can be loosely fitted in the second groove 9 and can be loosely fitted in the groove 92.

バネ７はコイルバネで、筒状金具内に装着されてフランジ６１に係合し、前記ロッド６をその一端が筒状金具５より突出する方向に付勢している。 The spring 7 is a coil spring, is mounted in the cylindrical fitting, engages with the flange 61, and biases the rod 6 in a direction in which one end thereof protrudes from the cylindrical fitting 5.

図１に示すように、平鋼よりなる主部材２１と、並列する主部材２１の両端に固定されるエンドプレート２２と、主部材２１と直交して固定されるクロスバー２３よりなるグレーチング２は、左右において主部材２１が一定区間切除され、各切除部分に納まる固定金具１はそれぞれ、フランジ５１をグレーチング２のエンドプレート２２に溶接にて固定することによりグレーチング２に第２の溝９を略上向きにして取付けられている。 As shown in FIG. 1, a grating 2 comprising a main member 21 made of flat steel, an end plate 22 fixed to both ends of the main members 21 arranged in parallel, and a cross bar 23 fixed orthogonally to the main member 21 is The main member 21 is cut off at a predetermined interval on the left and right sides, and the fixing metal fittings 1 housed in the cut portions are fixed to the end plate 22 of the grating 2 by welding, so that the second groove 9 is approximately formed in the grating 2. It is mounted facing upward.

なお、受枠３には、図１に示すように、ロッド６の延長線上にロッド一端が嵌合する嵌合孔３１を備えている。 As shown in FIG. 1, the receiving frame 3 is provided with a fitting hole 31 in which one end of the rod is fitted on the extension line of the rod 6.

本実施形態の固定金具１は以上のように構成され、グレーチング固定時においてはピン６２が第１の溝８の鉤溝８２に（図２）、操作把手６３が第２の溝９の鉤溝９２に遊嵌し、ロッド６一端が受枠３の嵌合孔３１を通り突出している（図５）。この状態よりグレーチング２の固定を解除するときには、第２の溝９の鉤溝９２に遊嵌して横倒しとなっている操作把手６３を手又は工具を用いて掴み、バネ７の作用に抗して横倒しのまま角溝９１の溝端に当たる限度まで後退させ、鉤溝９２より離脱させる。これに伴いピン６２も鉤溝８２より離脱する。同時にロッド６も後退して引込むが、その一端はなおも受枠３の嵌合孔３１に嵌合したままである。 The fixing bracket 1 of the present embodiment is configured as described above. When the grating is fixed, the pin 62 is in the groove 82 of the first groove 8 (FIG. 2), and the operation handle 63 is the groove in the second groove 9. The rod 6 is loosely fitted, and one end of the rod 6 projects through the fitting hole 31 of the receiving frame 3 (FIG. 5). When the fixing of the grating 2 is released from this state, the operation handle 63 which is loosely fitted in the flange groove 92 of the second groove 9 and is laid sideways is gripped by hand or a tool to resist the action of the spring 7. Then, it is retracted to the limit where it hits the groove end of the square groove 91 while being laid sideways and separated from the trough groove 92. Along with this, the pin 62 is also detached from the groove 82. At the same time, the rod 6 also retracts and retracts, but one end of the rod 6 is still fitted in the fitting hole 31 of the receiving frame 3.

操作把手６３を鉤溝９２より離脱させると、そのまま幅広の角溝９１内を図５の右方向に回動させる。これにより操作把手６３が起き上がりながらピン６２がコ字形の溝部８１に移動する。コ字形の溝部８１の軸方向と直行する区間において、ピン６２はバネ７の作用により溝の側壁面に押付けられて移動する。したがって操作把手６３を図５の右方向へ回動させる際には、該把手６３をバネ７の作用に抗して押込んだまま回動させる必要はなく、単に回動操作するのみでよい。操作把手６３を幅広の角溝９１の溝端に突き当たる限度まで回動させたのち、再度バネ７の作用に抗して角溝９１の溝端に突き当たる限度まで押し込む。これによりピン６２はコ字形部８１の軸方向に沿う区間を移動する。操作把手６３を角溝９１の溝端に突き当たる限度まで押込むと（このときロッド一端は受枠３の嵌合孔３１より離脱する）、その状態のまま図５の左方向へ回動させる。これに伴いピン６２はコ字形の溝部８１の軸方向と直交する区間を前記とは逆向きに移動する。この間、ピン６２は前記と同様、バネ７の作用によりコ字形の溝部８１の側壁面に押付けられて移動するため、操作把手６３はバネ７の作用に抗して回動させる必要がなく、単に回動操作するのみでよい。 When the operation handle 63 is detached from the ridge groove 92, the inside of the wide square groove 91 is rotated in the right direction in FIG. As a result, the pin 62 moves to the U-shaped groove 81 while the operation handle 63 rises. In a section perpendicular to the axial direction of the U-shaped groove 81, the pin 62 is pressed against the side wall surface of the groove by the action of the spring 7 and moves. Therefore, when the operation handle 63 is rotated in the right direction in FIG. 5, it is not necessary to rotate the handle 63 while pushing it against the action of the spring 7, and it is only necessary to perform the rotation operation. After the operation handle 63 is rotated to the limit where it hits the end of the wide square groove 91, it is pushed again to the limit where it hits the end of the square groove 91 against the action of the spring 7. As a result, the pin 62 moves along the axial direction of the U-shaped portion 81. When the operating handle 63 is pushed to the limit where it abuts against the groove end of the square groove 91 (at this time, one end of the rod is detached from the fitting hole 31 of the receiving frame 3), it is rotated to the left in FIG. Along with this, the pin 62 moves in the opposite direction to the section perpendicular to the axial direction of the U-shaped groove 81. During this time, the pin 62 is pressed against the side wall surface of the U-shaped groove 81 by the action of the spring 7 and moves as described above, so that the operation handle 63 does not need to be rotated against the action of the spring 7, and simply It only needs to be rotated.

操作把手６３は回動に伴い倒れ、角溝９１の溝端に突き当たる限度まで回動させると（図６）、横向きとなり、ピン６２は上記区間端に達する。ピン６２が該区間端に支持されることにより、ロッド一端は受枠３の嵌合孔３１より離脱したまま支持され、固定の解除状態が維持される。左右の両固定金具１による固定が解除されたのち、グレーチングは脱着が可能となる。 When the operation handle 63 falls down as it rotates and is rotated to the limit where it hits the groove end of the square groove 91 (FIG. 6), it becomes sideways and the pin 62 reaches the end of the section. By supporting the pin 62 at the end of the section, one end of the rod is supported while being detached from the fitting hole 31 of the receiving frame 3, and the fixed release state is maintained. After the fixing by the left and right fixing brackets 1 is released, the grating can be detached.

グレーチング２を受枠３に装着後、図６の状態より操作把手６３を掴んで図の右方向に回動させると、ピン６２もコ字形の溝部８１の軸方向と直交する区間を移動し、ピン６２が区間端に達すると、バネ７の作用によりコ字形の溝部８１を軸方向に前進する。これにより操作把手６３も角溝９１内を前進すると共に、ロッド６も一定量突出する。操作把手６３が角溝９１端に達し、ピン６２がコ字形の溝部８１を軸方向に限度まで前進して移動すると、操作把手６３を上記と逆向きに回動させ、ピン６２をコ字形の溝部８１の軸方向と直交する区間を移動させる。操作把手６３を角溝９１の溝端に突き当たる限度まで回動させ、鉤溝９２に達すると、ピン６２も鉤溝８２に達し、バネ７の作用で鉤溝８２に嵌合する。これと共に操作把手６３も第２の溝９の鉤溝９２に嵌合し、ロッド６も前進して、その一端を受枠３の嵌合孔に嵌合させる。左右の両固定金具１でロッド６一端を受枠３に嵌合させた状態で、グレーチング２が受枠３に固定される。 After the grating 2 is mounted on the receiving frame 3, when the operation handle 63 is grasped from the state shown in FIG. 6 and rotated to the right in the figure, the pin 62 also moves in a section perpendicular to the axial direction of the U-shaped groove 81, When 62 reaches the end of the section, the U-shaped groove 81 is advanced in the axial direction by the action of the spring 7. As a result, the operation handle 63 also moves forward in the rectangular groove 91, and the rod 6 protrudes by a certain amount. When the operation handle 63 reaches the end of the square groove 91 and the pin 62 moves forward by moving the U-shaped groove portion 81 to the limit in the axial direction, the operation handle 63 is rotated in the opposite direction to the above, and the pin 62 is The section orthogonal to the axial direction of the groove 81 is moved. When the operation handle 63 is rotated to the limit where it abuts against the groove end of the square groove 91 and reaches the groove groove 92, the pin 62 also reaches the groove groove 82, and the spring 7 acts to fit the groove groove 82. At the same time, the operation handle 63 is also fitted into the groove 92 of the second groove 9, and the rod 6 is also advanced, and one end thereof is fitted into the fitting hole of the receiving frame 3. The grating 2 is fixed to the receiving frame 3 in a state in which one end of the rod 6 is fitted to the receiving frame 3 with the left and right fixing brackets 1.

本実施形態によると、ロッド端が受枠３の嵌合孔３１に嵌合した状態で、ピン６２が前述するような複雑な動きをしない限り、ロッド端が嵌合孔３１より外れることはなく、固定状態が確実に維持される。また固定時には操作把手６３を単に回動操作するだけでよく、固定解除時でも操作把手６３をバネ７の作用に抗して押し動かして回動操作するだけでよいから、固定やその解除のための作業が容易である。操作把手６３はまた、固定時には横向きに倒れ、グレーチング２より突出しないため、車両等の走行時に車両等と当たって車両等の走行に支障を来たしたり、歩行時につまずいたりするおそれがない。 According to the present embodiment, the rod end does not come off the fitting hole 31 unless the pin 62 moves in a complicated manner as described above with the rod end fitted in the fitting hole 31 of the receiving frame 3. The fixed state is reliably maintained. Further, the operation handle 63 only needs to be rotated at the time of fixing, and the operation handle 63 only has to be pushed against the action of the spring 7 to rotate at the time of releasing the lock. Is easy. Further, since the operation handle 63 falls sideways when fixed and does not protrude from the grating 2, there is no possibility of hitting the vehicle or the like during traveling of the vehicle or the like, causing trouble in traveling of the vehicle, or tripping during walking.

前述する実施形態の固定金具１は、排水桝の受枠３に装着されるグレーチング２に取付けられ、該グレーチング２を固定するようになっているが、側溝の受枠に装着されるグレーチングについても同様にして取付けられ、固定される。
前記実施形態ではまた、グレーチングは受枠に固定されるようになっているが、側溝又は排水桝に直接固定される。この場合にはしたがって、側溝又は排水桝に前記ロッド６の延長上に嵌合凹部が形成され、前記ロッド６が該嵌合凹部に嵌合される。 The fixing bracket 1 of the embodiment described above is attached to the grating 2 attached to the receiving frame 3 of the drainage basin and is adapted to fix the grating 2. The same applies to the grating attached to the receiving frame of the side groove. Installed and fixed.
In the above embodiment, the grating is also fixed to the receiving frame, but is directly fixed to the gutter or the drain. In this case, therefore, a fitting recess is formed on the extension of the rod 6 in the side groove or the drain, and the rod 6 is fitted into the fitting recess.
