Title: Lock for lid of underground structure
Inventor: KANIE NOBORU
IPC: E02D29/14
Filed: 1997-10-27
Abstract: PROBLEM TO BE SOLVED: To prevent a manhole lid from breaking when the lid is opened and improve storage and transport efficiency by providing an engagement member on a frame and an engagement edge on a lid. SOLUTION: An engagement member 3 is comprised of a hook 3a, a pin 3b, a control member 3c and a balancing portion 3d. The hook 3a is hooked so as to be engaged with an engaging edge provided on a lid. The engagement member 3 is supported rotatably in a pin support hole given in an engagement member-receiving portion 1a. A slope is formed in the inside of the lid in contact with the head of the hook 3a of the engagement member 3. By rotating the manhole lid circumferentially, the head of the hook 3a in contact with the slope slides on the slope. As a result, the engagement between the hook 3a and the engagement edge is released, thereby unlocking the frame 1 and the lid. Therefore, since the lid itself has no complex engagement member, the lid excels in horizontal openability and ease of maintenance and transport.

Abstract: PURPOSE:To detect the position of a machine having a long moving stroke easily by arranging plural main scales in the displacing direction, and using a slider, which includes a means for detecting the position information of the main scale, at two points separated in the displacing direction. CONSTITUTION:Two grid groups GP1, GP2 of an index scale 7 are separated from each other by (d) in the displacing direction so as to detect the position information of two positions separated by (d) in the displacing direction. In a light receiving unit 8, two light receivers SP1, SP2 are separated from each other by (d). Consequently, the position information S1 is obtained by the combination of the grid group GP1 and the light receiver SP1, and the position information S2 is obtained by the combination of the GP2 and the SP2. On the other hand, in a main scale 6, a clearance C between scales 6 adjacent to each other is formed smaller than the clearance C' between the grid groups GP1, GP2. With this structure, even in the case where a slider 20 passes a joint part of the scales 6, since any one of the grid groups GP1, GP2 faces a part without a joint, correct information is always obtained from any of the position information S1, S2.
