Abstract

PROBLEM TO BE SOLVED: To provide a ditch cover hinge, which saves the need for movement or remove work of a ditch cover by installing a hinge at a center between two ditch covers so that the ditch covers can be turned to open and stand still, although dumping snow into a groove and cleaning require work to remove many metal ditch covers with weight of more than 15 kg and move them to another place, which is a backbreaking work even for an adult male.SOLUTION: A hinge is welded to a center between two ditch covers so as to be installed in a suspended state as welding the two ditch covers results in their weight of more than 30 kg. Thus, the ditch covers can be set in a short time by turning and opening and making the ditch covers stand still.SELECTED DRAWING: Figure 1

Description

この発明は、上ぶた式側溝用の格子型溝蓋の丁番、に関するものである。The present invention relates to a hinge for a lattice-type groove cover for an upper lid side groove.

溝への雪捨て・清掃等で溝蓋を開ける手段は、大型の落蓋式等を除くと無かった。有ったとしても、蓋に組み込み式で後付のものはなかった。There was no means to open the groove lid by throwing snow away or cleaning the groove, except for a large drop lid type. Even if there was, there was no retrofit on the lid.

溝蓋は、金属製であり重さは溝幅３０ｃｍ・長さ１ｍの普及品等では１５ｋｇを超えており、取り除いて邪魔にならない場所への移動は成人男子でも骨の折れる作業であるため、その移動を不要にすることを目指した。Since the groove cover is made of metal and the weight exceeds 15 kg for a popular product with a groove width of 30 cm and a length of 1 m, moving to a place where it does not get in the way is an arduous task even for an adult male. We aimed to make that movement unnecessary.

２枚の溝蓋を１集合体とし、その間に丁番を取り付け開閉式とした。Two groove lids were made into one assembly, and a hinge was attached between them to make it openable.

一般に、２枚の溝蓋間の丁番設置作業は、取り付け部間の隙間が必要であるがその隙間は、現行品ではほぼ無い。
よって溝蓋の長さを切って溶接をする等の作業が必要であった。
本特許は、溝蓋への一切の切断、加工の省略・数分の短い設置作業時間を目指した。In general, the hinge installation work between two groove lids requires a gap between the mounting portions, but the gap is almost absent in the current product.
Therefore, work such as cutting the length of the groove lid and welding it was necessary.
This patent aimed at a short installation work time of several minutes, omitting any cutting to the groove lid, omitting processing.

丁番を装着後、片方の溝蓋の端を持ち上げ文字通り蓋を開けるような構造にした。After installing the hinge, the structure was such that the end of one of the groove lids was lifted to open the lid literally.

丁番の機能を持たせつつ、１８０度ではなく１００度前後開いたところで停止するような機能を追加した。Added a function that stops when the door is opened around 100 degrees instead of 180 degrees while having a hinge function.

持ち上げ重量は半減し、非力の婦女子でも作業が可能となった。Lifting weight has been halved, and even less powerful women can work.

本発明一台で、溝蓋２枚分の面積相当の側溝への雪捨てや清掃が可能となり、溝蓋一枚おきに溝蓋丁番を設置し、２か所同時に開ければ、僅かの時間で長さ２ｍの溝蓋の無い空間が側溝に出現する。With one unit of the present invention, it becomes possible to throw away snow and clean the side grooves equivalent to the area of two groove lids, and install groove lid hinges every other groove lid and open two places at the same time. Thus, a space without a groove lid having a length of 2 m appears in the side groove.

約１００度の角度の溝蓋の停止は、作業終了時の作業を軽便にする。Stopping the groove lid at an angle of about 100 degrees makes the work at the end of the work easier.

蓋を開けての作業は立ち上がった蓋が目印となり、遠方からも側溝の蓋が開けられているのが一目瞭然となり、思いがけなく安全性も追加された。When the lid was opened, the raised lid became a landmark, and it was obvious that the lid of the gutter was opened from a distance, adding unexpected safety.

側溝がカーブでも、固定部分がない連結集合体なで設置が可能。Even if the side groove is curved, it can be installed as a connected assembly with no fixed part.

溝蓋の単辺に丁番を設置し、長辺が開口部となったことで、道路側・住宅側両方から雪捨て・清掃が可能である。By installing a hinge on one side of the groove cover and opening the long side, snow can be thrown away and cleaned from both the road side and the house side.

本発明の溝蓋丁番を実施するため、以下本発明の実施例を、図面に基づいて説明する。In order to implement the groove lid hinge of the present invention, embodiments of the present invention will be described below with reference to the drawings.

Ａ図は、本特許設置中の平時の図で、格子状の市販の溝蓋（１）に、本発明の溝蓋丁番（２）が、取り付けてある図であり、解り易くするため左側の溝蓋は省略した。 Fig. A is a view at the time of installation of this patent, in which the groove lid hinge (2) of the present invention is attached to a lattice-shaped commercially available groove lid (1). The groove cover was omitted.

Ｂ図は、平時における２枚の格子状の市販の溝蓋（１）と、本発明の溝蓋丁番（２）の位置関係を断面図で表している。 FIG. B shows a cross-sectional view of the positional relationship between two lattice-shaped commercially available groove lids (1) and the groove lid hinge (2) of the present invention during normal times.

Ｃ図は、溝蓋解放時における２枚の格子状の市販の溝蓋（１）と、本発明の溝蓋丁番（２）の位置関係を断面図で表している。 FIG. C shows a cross-sectional view of the positional relationship between two lattice-shaped commercially available groove lids (1) and the groove lid hinge (2) of the present invention when the groove lid is released.

一点破線（３）は、側溝の上面（ＧＬ）であり、溝蓋の耳部分（１−１）は側溝との接触部分であり溝蓋の回転時の支点（１−２）となる。A one-dot broken line (3) is the upper surface (GL) of the side groove, and an ear portion (1-1) of the groove lid is a contact portion with the side groove and serves as a fulcrum (1-2) when the groove lid rotates.

溝蓋丁番（２）の正面図は、設置時、三か所に角度があるＶ字状であり底辺の角度部分に丁番（２−１）が設置されていて、左右に開閉でき、両端は外に向かっての、逆Ｊ字（２−２）に曲がっている。The front view of the groove lid hinge (2) is V-shaped with an angle at three locations when installed, and the hinge (2-1) is installed at the angle part of the bottom, and can be opened and closed left and right, Both ends are bent in an inverted J-shape (2-2) toward the outside.

取り付けは、Ａ図のように、溝蓋の格子部分内側から４列目に、下部から本体の逆Ｊ字（２−２）の部分をひっかけぶら下げて完了する。 As shown in FIG. A, the attachment is completed by hanging the inverted J-shaped (2-2) portion of the main body from the bottom in the fourth row from the inside of the lattice portion of the groove lid.

Ｂ図において、格子状の市販の溝蓋（１）の一方の端を持ち上げると、中央、溝蓋の回転時の支点（１−２）を中心として回転し、直角を過ぎ１００度位に達した時、Ｃ図となる。In Fig. B, when one end of the lattice-shaped commercially available groove lid (1) is lifted, it rotates around the center, the fulcrum (1-2) when the groove lid rotates, and reaches about 100 degrees past a right angle. When it does, it becomes C figure.

Ｃ図に於いて、
▲１▼ 溝蓋丁番（２）の、への字角部（２−３）と、溝蓋の格子下部内側から３列目（１−３）の底辺部の接触部。
▲２▼ 溝蓋の格子下部内側から１列目（１−４）の底辺部と、溝蓋丁番（２）の接触部分。
▲３▼ 丁番（２−１）の回転中心。
上記３か所が、ほぼ一直線となり回転が固定され本目的を達成する。In Figure C,
(1) A corner portion (2-3) of the groove lid hinge (2) and a contact portion of the bottom portion of the third row (1-3) from the lower grid inner side of the groove lid.
(2) A contact portion between the bottom of the first row (1-4) and the groove lid hinge (2) from the inside of the lower part of the lattice of the groove lid.
(3) Center of rotation of hinge (2-1).
The above three places are almost in a straight line and the rotation is fixed to achieve this object.

上記の溝蓋丁番は、鎖・紐など柔軟性のある材質を、停止角度を設定し溝蓋の底部に張った状態で設置すれば、丁番（２−１）は、不要になる。If the groove lid hinge is installed with a flexible material such as a chain or string in a state where the stop angle is set and stretched to the bottom of the groove lid, the hinge (2-1) becomes unnecessary.

逆Ｊ字（２−２）の部分２か所は、一般の丁番に代用可能である。The two portions of the inverted J (2-2) can be substituted for a general hinge.

丁番（２−１）を２個にすれば、溝蓋丁番（２）上下間の距離を短く出来る。If there are two hinges (2-1), the distance between the upper and lower sides of the groove lid hinge (2) can be shortened.

溝掃除・溝への雪捨ての面倒さに大きく加担している一つが、溝蓋の脱着であり、その大幅な軽減は、婦女子だけでの作業を可能とする。 One of the major contributions to the hassle of cleaning the grooves and throwing snow into the grooves is the removal and installation of the groove cover, which can be reduced by women and girls alone.
