Abstract
The device has an axially movable tube (17) and a piston (18) received in an oil cylinder. In the event of shock loading on the hinge, valves (32,32a) open under the oil pressure to absorb the shocks. When the tube moves vertically, the load produced by hydraulic pressure, is applied uniformly to a shaft (40). Preferably, the device is provided with a release mechanism in the form of a cylinder arrangement (70), activated by heat, in the event of fire.

A!-_--.-ROUND OF TH7 1-NVE'-N-TION Ln the prior art, a hinge has played only a ccnneczion between a door and a framework c'nerecf. The hinge is madle se;a_racedly from a I- ' ' i - - IV and S._cc.K-a:)sor,:D.ng device which renders the door to be close" s,cw- I I n the upper por-.ion of the a-_-:o7mancaIIv and which is typically located c.L L door and connecced be:ween the door and the fra_-newc-,'r:.
The shock-absorbing device is so connplicaied:.hat -.r-----,ble shooting thereof frequently takes place-And --he device has to be I ISr lied only onto the upper portion of the door in a manner 'ha the Lal L device is exposed, out of. the door. Therefore, in the shock- absorbing device of the prior arz, chere are problems in installation in a restricted area,and from an aesthetic point of view and high cost In order to solve the above problems, the inven-or o, the presen: invencion disclosed Korean Patent No. 156,093 which had been, granted and entitled "HYDRAULIC AUTOMATIC SHOCK-ABSORBING =N-GE" wnerein the hinge has a piston on the end thereof ant a cylinder having I I- v e an a a rec.procat-ng pipe cherein. The piston has a sw'tch'ng va."
