摘要： PURPOSE:To ensure airtightness by constituting a plug door device so that the first and second interlocking bodies of the lower part of a door are interlocked with the first and second guide members, a rail body is interlocked with a holding member and that an auxiliary cylinder energizes the lower part of the door to the inward of a car when the door is completely shut. CONSTITUTION:When a door 3 is moved in a shutting direction (b) by operation of a going in and out cylinder and an opening and shutting cylinder, the first interlocking body 31 is fitted between a regulatory face 33a of a stopper member 33 and the first guide member 27. When the door 3 is completely shut, the first interlocking body 31 and the regulatory face 33a are closely connected to each other. The first interlocking body 31 and second interlocking body 32 are respectively interlocked with the first guide member 27 and second guide member 28 in a door front side end of the door 3, and a rail body 35 is interlocked with a holding member 34 in the rail of the door, In addition, a link member 22b, a bearing frame 24 and the door 3 are energized to the inward of a car by operation of an auxiliary cylinder 41.

摘要： PURPOSE:To detect a door-catch with high degree of accuracy to reopen and reshut automatically a door and to promote safety by providing an encoder, position, speed detection means, reference speed setting section and comparison section, etc., to a door opening and shutting controller operated with a pneumatic cylinder. CONSTITUTION:A door is opened, shutted and driven with a pneumatic cylinder 15 and, at the same time, a door position and a moving speed are detected with pulse signals of an encoder 16 provided to the cylinder 15 through a position detecting means 17 and a speed detection means 18. A standard speed as a decision basis of door-catch detection is set in correspondence with position signals from the position detection means 17 in a reference speed setting section 19, the reference speed is compared with speed data from the speed detection means 18 by a comparison section 21 to judge on whether or no there is the door-catch, so that opening and shutting signals can be outputted to a door opening and shutting control section 20. A correction means consisting of a decision section, computing store section, correction operating section, etc., is added, and it is so constituted that the reference speed can be set more accurately.

摘要： PURPOSE:To prevent the contact of a door with a side wall of a car by having such a construction as a slide mechanism does not operate unless the movement in the corbel direction of the door by a link mechanism is completed or the link mechanism does not operate during the movement of the door. CONSTITUTION:When a door 3 makes open opeation, an open and close cylinder 9 and an in and out sylinder 14 are operated to project each of piston rods 9a and 14a. After that, the door 3 and second guide mechanism 5 are guided by the first guide mechanism 4, and they are corbeled in the direction of (a). Then, when the piston rod 14a reaches the moving end of the corbel direction, a roller plunger 31a of a limit valve 31 is pushed and reduced by a limit plate 32. When the door 3 is moved in the corbel direction by a specific size, the piston rod 9a is only projected. In addition, a sliding piece 5b of the second guide mechanism 5 and a coupling metal fixture 8 are moved in the (c) direction as an open direction along a guide rail 5a and, at the same time, the door 3 is moved in the (c) direction.
