Abstract: An article conveying apparatus (1) according to an embodiment includes: a hopper (60/70) that temporarily stores an article charged from an outside and discharges the article downstream; a driver (10) that dives the hopper; and a main body (100) to be attached with the driver, wherein the main body includes: a top plate (110) that has a plane in a horizontal direction; and a side surface (120) to be attached with the driver, and the side surface has: a first surface (120A) that stands up in a vertical direction and is to be connected to the top plate; and a second surface (120B) that is formed continuously with the first surface, is attached with the driver, and is inclined in a direction of going toward a center axis (0) of the main body as going downward in the vertical direction.

Abstract: The invention provides a shock absorbing structure capable of turning the function of the shock absorber on and off according to the level of shock during collision, thereby reducing the frequency of replacing shock absorbers. On a rear surface of a load operating unit 11 constituting a shock absorbing device 10A are attached a load transmitting shaft 12 and a shock absorber 13. The load transmitting shaft 12 is passed through the center of the shock absorber and is connected to a supporting unit 14 via a pin 15 that extends toward the radial direction. The rear end of the shock absorber 13 faces the supporting unit 14 with a clearance therebetween. The pin 15 has notched grooves 21 formed thereto. When small load is applied, the load is transmitted from the load operating unit 11 through the load transmitting shaft 12, the pin 15 and the supporting unit 14 to the main body, so that the load is not applied on the shock absorber 13.

Abstract: A car structure is provided which has the required strength against vertical load and vibration while avoiding increase in weight of the structure. At an entrance 6 of the railroad car structure 20 in which a side structure 2 is formed by a hollow member, the side structure 2 and a frame 7 are coupled via an L-shaped fitting 10. The L-shaped fitting 10 consists of a first joint part 10a which is in the form of a plate and couples a vehicle outer face plate 8 and a vehicle inner face plate 9 and a second joint part 10b which is in the form of a plate and butt welds a part of the first joint part 10a near the vehicle outer face plate 8 and the frame 7. Plate thickness of the second joint plate 10b is larger than plate thickness of the vehicle outer face plate 8. As a result, the required strength against vertical load can be ensured without increasing the plate thickness of the vehicle outer face plate 8, in other words, with little increase in weight of the structure.

Abstract: There is provided a vehicle equipped with a shock absorbing structure that can absorb collision energy stably under all collision conditions to ensure the safety of crew members and passengers. The shock absorbing structure is arranged in an end part of the vehicle. The shock absorbing structure comprises an upper-stage shock absorbing structure 100 that is arranged in an upper part of a crushable zone to absorb collision energy by being crushed by a predetermined load, a lower-stage shock absorbing structure 120 that is arranged in a lower part of the crushable zone to absorb the collision energy by being crushed by the predetermined load, and a middle-stage shock absorbing structure 110 that is held between the upper-stage shock absorbing structure 100 and the lower-stage shock absorbing structure 120 arranged over and under the middle-stage shock absorbing structure 110.

Abstract: The invention provides a car body of a railway vehicle capable of absorbing the energy caused when collision occurs to the end of the car body. The present invention comprises a strength member 15 disposed along the circumferential direction of the car body on the end of the car body, a strength member 16 disposed along the circumferential direction at a position rearward from the member 15, rib members 17 disposed along the longitudinal direction of the car body and connecting the two strength members, and an outer panel 18 covering the same. The longitudinal direction of the rib member 17 corresponds to the longitudinal direction of the car body. The rib member 17 is composed of two flanges 17c, 17d and a web 17b connecting the two flanges, and the side having the web 17b is welded to the outer panel 18 via fillet welding. A notch 21 opened to the edge of the flange is formed on the flange at the center of the longitudinal direction of the rib member 17.

Abstract: A railway vehicle having an impact energy absorbing device capable of avoiding coincidence between starts of deformation of the impact energy absorbing device in the event of collision to reduce the pressure collapse peak load and, hence, loads on the vehicle body, passengers and so on in the case of application to a transportation apparatus such as a train in particular. The impact energy absorbing device has a plurality of energy absorbing members 11 and 12 which pressure-collapse in the event of collision to absorb impact energy, and which are mounted in a predetermined region in the longitudinal direction of the body of a vehicle while being spaced apart in the car body width direction. Front ends of the energy absorbing members 11 and 12 in the collision direction are shifted to a plurality of positions (jutted out by ?L).

Abstract: A vehicle such as a railroad car is constructed by connecting together side and roof blocks, each equipped with interior components, in a manner to improve the outer appearance of the connections between the side and roof blocks. Longitudinal beams of the side blocks are in contact with the under surfaces of gutters formed by the outer plate of the roof block. The side and roof blocks, equipped with the interior components, are connected together at the gutter portions by a welding which can be conducted solely outside the vehicle. Inside the vehicle, the longitudinal beams and joints secured to the side blocks are connected to lateral beams of the roof block by rivets. Thereafter, a third interior plate is provided between interior plates of the side and roof blocks. Since the connections are formed at the gutter portions, the connecting operations can easily be conducted outside the vehicle and in a manner to assure a good outer appearance.
