摘要： PURPOSE:To prevent a body from being damaged due to an unexpected accident by applying the constitution wherein a coupler so installed horizontally at the wheel end side of a cushion body as to be capable of oscillation is positioned in such a way as to be housed in the body, while the the coupler is so connected to the end of a coupling drum having a contact piece at the forward end thereof as to be capable of oscillation as well. CONSTITUTION:A coupler 5 is normally housed within a body, and a coupling drum 2 itself or a contact piece 2 fitted thereto is positioned at the end of the body. In this state, even if vehicles collide with each other or a stop, a body load is absorbed by a rubber cushion 1 via the aforesaid contact piece 12, thereby preventing the damage of the body. In this case, the contact piece 12 is provided inside the end of the body and a cover 18 constituting the front end of the body can be easily changed. It follows, therefore, that the damage, if any, can be minimized.

摘要： PURPOSE:To aim at the promotion of lightweightiness in a underframe by installing an intermediate molding plate, formed in corrugation continued in a body cross direction, between both upper and lower plate set up between both side-beams. CONSTITUTION:A lower plate 2 is set up over space between both side-beams 1 installed at both sides in a body cross direction, and in the side beam 1, a flange receiving an end of the lower plate 2 is installed in a vertical intermediate part. In the upper part of this lower plate 2, an intermediate molding plate 3 with corrugation continued in the body cross direction is provided. In addition, an upper plate 4 is installed in the upper part of this intermediate molding plate 3, and it is attached so as to sandwich the intermediate molding plate 3 together with the lower plate 2. With this constitution, such a structure as similar to a truss construction is formed there by the lower plate 2, the intermediate molding plate 3 and the upper plate 4. Accordingly, it has ample strength as an underframe and, what is more, lightweightiness in this underframe is well promotable.

摘要： PURPOSE:To enable easy execution for adjustment of a track girder to forms by thrusting a packing in V-shaped section into an aperture between an underlying form and a sidewall form. CONSTITUTION:To an arm 9 supported by a sidewall form 1, an actuator 4 for thrusting a rubber packing 3 in V-shaped section into an aperture formed between the sidewall form 1 and an underlying form 2. A parallel link 10 is then annexed to the actuator 4. A thruster 11 is connected to both of the actuator 4 and the parallel link 10 and at the tip of the thruster, a supporting frame 7 is supported so that it becomes capable of swinging. A return spring 5 that works in the direction of retracting the actuator 4 is also provided. With such arrangement of devices, efficiency of work can be enhanced with improved workability.

摘要： PURPOSE:To simplify a structure by constituting a monorail point switch device with fixed beams, a mobile beam rotatably connected to the end section of the fixed beam, and flexible guide plates fitted to the beams at positions apart from connection sections between the fixed beams and the mobile beam on their end sections. CONSTITUTION:A mobile beam A is rotatably connected to the end section of a fixed beam A among the fixed beam A and fixed beams C and D. Flexible guide plates 1 and 2 are fixed to the beam A on one ends (a) and (a') corresponding to both sides of the beams A and B and movably fitted to the beam B on the other ends (b) and (b'). End sections (a) and (a') and end sections (b) and (b') are fitted at positions apart from the connection point 0 of the beams A and B by the preset distances, thus the plates 1 and 2 are curved as the beam B is moved so that no shock is applied to a train when it passes. The structure can be simplified as compared with a conventional joint type point switch track beam.

摘要： PURPOSE:To enable on-off getting to be safely further promptly attained of a passenger riding in a wheelchair on a platform by providing a conveyer truck, loading the wheelchair, in a position corresponding to a stopped vehicle gate of the platform and a crossing plate over the vehicle gate in a point end part of the conveyer truck. CONSTITUTION:By a command from a boarding indicator 5, a conveyer truck 6 is moved to a boarding port from a standby position, opening a movement preventing plate 10, and a passenger manipulates a wheelchair 12 riding in the truck 6. The indicator 5 is operated, performing storage of the preventing plate 10 and fixing action of the wheelchair 12, and the passenger waits till a vehicle 1 is stopped. Next the vehicle 1 is advanced in a line to a platform 18, when the vehicle is stopped in a stop position, a crew 2 opens a door 17 different from an on-off getting door for an ordinary passenger. Under this condition, the truck 6 detects the door 17 for its opened condition, moving to a side of the vehicle 1, and a crossing plate 11 is rolled and linked to a gate in a position where the truck 6 approaches the vehicle 1 in the shortest distance. Next the passenger on the wheelchair 12 rides in the vehicle 1, and closing the door by operation of the crew 2, the truck 6, detecting the door 17 to be closed, is retracted to the standby position.

摘要： PURPOSE:To reduce the noise generated from a coupler by constructing the title device of a connecting shaft with a flange formed at its intermediate part, a precompressed rubber buffer fitted at the connecting shaft and a vertical pin with a rubber bush for coupling the title device with each car body. CONSTITUTION:A vertical pin 4 for coupling both ends of a rod type coupler 3 with a coupler receiver 2 is vertically disposed in its center axis and formed of a ring 19 and a rubber bush provided by vulcanizing adhesion. A cylindrical buffer 5 is provided with ringular rubber buffers 9a, 9b in its interior; and the one end of the buffer 5 is formed with smaller outer diameter as a coupling end 14, and a hole for inserting the vertical pin 4 is provided at its end part. A flange 10 formed approximately at the center part of a connecting shaft 11 is positioned between the ringular rubber buffers 9a, 9b, and the connecting shaft 11 is disposed with both its ends piercing through the ringular rubber buffers 9a, 9b. A screw 18 is further formed at the end part of the connecting shaft 11, a guide ring 15 is screwed with the screw 18, and a cylinder 16 with a slidable guide ring 15 is fittingly provided inside the coupling end 14.
