る。 That is, the present invention provides a cover body 1 for underground structures with an insertion hole 3 for a crowbar 2, an engagement hole 4 is formed in the wall of the hole, and a distal end hook 5 that can be engaged and detached is provided in the engagement hole 4. A hook body 6 having a pivot body 8 is attached to a frame body 7 that receives the lid body 1.
The other end of the hooking body 6 is provided with a weight part 9 that extends outward from the frame body 7 and engages the hook part 5 with the engagement hole 4, and the engagement is released by inserting the crowbar 2. It is characterized by this. The insertion hole 3 of the crowbar 2 in the embodiment shown in FIGS. Insertion hole 3 in Figure 3
The difference is that the bottom portion 3a is only the minimum necessary size.
Lower surface 4a of the inner lower end of the engagement hole 4, that is, the engagement end
The front upper surface 5a of the hook portion 5 of the hook locking body 6 is an inclined surface, and is automatically locked when the lid is closed. The hooking body 6 has a substantially J-shaped side surface and is pivotally supported near the boundary between the bent part and the straight part, and the support shaft 8 is a pair of bearing pieces that are engaged with the inner flange 7a of the frame body 7. 10,1
It is installed at 0. The straight portion extending outward of the frame 7 passes through an opening 11 formed in the frame 7 between the shaft support pieces, and the weight portion 9 is inserted into a housing 12 provided outside the opening 11.
is housed so that it can be moved up and down. The frame body 7 is the lid body 1
Although the description and illustration assume a receiving frame for receiving a manhole iron cover, the present invention is not limited to this, and can be applied to, for example, a raised frame or other general frame. Note that 13 is a catch hook.
叙上の構成において、施錠を外すには、通常開
蓋作用で行うように、バール２の先端屈曲部２ａ

込孔３の底部内縁との係合が外れ、バール２でこ
じつて持上げるときには既に解錠状態となつてい
るから容易に蓋本体１を枠体７に押込めば閉蓋と
同時に施錠されるのは前述した通りである。 In the configuration described above, in order to unlock the lock, as is normally done by opening the lid, press the bent end portion 2a of the crowbar 2.
All you have to do is insert it into the insertion hole 3 and lift the edge of the lid body 1 using a screw. At that time, by inserting the crowbar 2 into the insertion hole 3, the tip bent portion 2a hits the front upper surface 5a of the hook portion 5 and pushes it inward, so that the engagement with the bottom inner edge of the insertion hole 3 is disengaged. As mentioned above, when the lid is forcibly lifted with the crowbar 2, it is already in the unlocked state, so if the lid main body 1 is easily pushed into the frame 7, the lid is locked at the same time as the lid is closed.
従つて本考案によればバール２が差込まれる孔
３の孔壁に係合孔４を形成し、バール２の差込み
により解錠することができるので、バール２の差
込みと同時に蓋をこじつて開蓋することが可能と
なり、また蓋本体１には既存のバール差込み孔に
係合孔４を設けるだけであるから容易に実施でき
かつ重量の増加もない特徴がある。 Therefore, according to the present invention, the engagement hole 4 is formed in the hole wall of the hole 3 into which the crowbar 2 is inserted, and the lock can be unlocked by inserting the crowbar 2. Therefore, the lid can be pried open at the same time as the crowbar 2 is inserted. The lid can be opened, and since the lid main body 1 is simply provided with the engagement hole 4 in the existing crowbar insertion hole, it can be easily implemented and there is no increase in weight.
