[Structure] The bottoms of both sides of the groove lid are partially cut out to form a gap so that a sandwiching metal for lifting the lid can be freely opened and closed.

Description

[Detailed description of the device]

【０００１】[0001]

[Industrial applications]

この考案によれば溝フタの上げ降ろしがスムーズになり，作業能率の向上につながるものである。 According to this invention, it is possible to smoothly raise and lower the groove lid, which improves work efficiency.

【０００２】[0002]

[Prior art]

従来の溝フタは地面に降ろしたときフタと地面との間に隙間がないので，挟み金貝の開閉が難しく，フタを降ろす場所に隙間を作るために二本の角材を敷いてておく必要があった。 Since the conventional grooved lid has no gap between the lid and the ground when it is lowered to the ground, it is difficult to open and close the sandwich shell, and it is necessary to lay two timbers to make a gap at the place to lower the lid. was there.

【０００３】[0003]

[Problems to be solved by the device]

これは次のような欠点があった。溝フタを降ろそうとする位置に二本の角材を敷く必要があるために，降ろす位置が限定されるし手間もかかる。 This had the following drawbacks. Since it is necessary to lay two timbers at the position where the groove lid is to be lowered, the lowering position is limited and time-consuming.

【０００４】[0004]

[Means for Solving the Problems]

既製の溝フタについては従来どうりの上げ降ろしになるが，今後製造する溝フタについては図１のように底部を一部改良したものにする。 The groove lids that have already been manufactured can be raised and lowered as usual, but the groove lids that will be manufactured in the future will have a partially improved bottom as shown in Fig. 1.

【０００５】[0005]

[Work]

溝フタを直接地面に降ろしてもフタの両側底面に隙間があるため，抵抗なく挟み金具が自由に開閉できる。 Even if the groove lid is directly lowered to the ground, there is a gap on the bottom surface on both sides of the lid, so the clamps can be freely opened and closed without resistance.

【０００６】[0006]

【Example】

以下本案の実施例について説明する。挟み装置で持ち上げた溝フタを地面に降ろしたとき（図２）（イ）フタ両側底向に切り欠いだ隙間があるため挟み金具は自由に広げられ，フタをそのまま地面に降ろすことができる。（ロ）持ち上げるときは挟み金具を広げてフタの底面まで下げてレバーを離せばフタを挟んで持ち上げることができる。 An example of the present invention will be described below. When the groove lid lifted by the clipper is lowered onto the ground (Fig. 2) (a) There is a notch in the bottom of both sides of the lid, so the clamp can be freely opened and the foot can be dropped directly onto the ground. . (B) When lifting, you can lift the clip by opening the clamp and lowering it to the bottom of the lid and releasing the lever.

【０００７】本案は以上のような要領で溝フタの上げ降ろしをする際に挟み金具が自由に開閉できるので楽に作業が進められる。According to the present invention, when the groove lid is lifted and lowered in the above manner, the sandwich metal fittings can be freely opened and closed, so that the work can be easily carried out.

【０００８】[0008]

[Effect of device]

本案は以上のように簡単な改良であるが，溝フタの両側底部を一部切り欠ぐことで地面とフタの間に隙間ができるため，溝フタを降ろすときに角材が不要で，したがって平坦地であれば降ろす場所も選ばず，作業能率も向上するという特長がある。 Although this plan is a simple improvement as described above, since a gap is created between the ground and the lid by notching the bottoms on both sides of the groove lid, a square timber is not required when lowering the groove lid, and therefore a flat surface is obtained. If it is a land, it can be placed anywhere and the work efficiency is improved.
