Abstract: There is provided a recoil shock device capable of obtaining the same recoil shock as that in a case where the weight of a piston is increased, without increasing the weight of the piston by separately providing a movable part and a weight of a piston/cylinder. There is also provided a recoil shock device capable of obtaining a recoil shock similar to that in a real gun, without damaging the outer appearance of a gun. In order to drive a weight to obtain imitated recoil, i.e., a recoil shock by operation of a movable part in a piston/cylinder which generates compressed air, a communicating part 31 which is moved in its retreating direction by the movable part 13 is provided, and a recoil spring 35 which receives a force transmitted to the weight 33 via the communicating part 31 by the movable part 13 so as to be in a compressed state is provided.

Abstract: A safety device in an imitation gun having a magazine mounted removably to a gun main body for preventing the risk of discharge of a remaining bullet which can take place after removing the magazine from the gun main body. In the imitation gun having the magazine being mounted removably to the gun main body and a piston device for supplying a bullet inside the magazine to a bullet loading part of the gun main body and injecting compressed air to the bullet arranged in the bullet loading part, a trigger member 15 having a engagement counterpart for engaging with an engagement part at a side of a piston of the piston device 22 in order to retract the piston along with a discharge operation at a driving part provided in the gun main body and advancing the piston by disengagement of the engagement is provided.

Abstract: Provided is a model train, which can be disassembled, when not used, into the size of one layout element but can be extended, when used, to a size according to a space. In the model train, rail elements including straight, curved and terminal ones are laid on layout bases to form layout elements, and the layout elements are connected to constitute predetermined running lines. The layout elements 11, 12 and 13 are provided at their connecting end portions 14, 15, 16 and 17 with at least one mechanical joint means composed of a recess 19 and a protrusion 18, which can fit each other thereby to constitute a layout, in which the layout elements are mechanically jointed and integrated by the aforementioned joint means. Rail elements 21 and 22 are connected by rail connecting means disposed at a predetermined position of the layout elements, and the layout elements are jointed by the aforementioned joint means so that the rail elements are also electrically connected with each other.

Abstract: Cost for electric power for operation of a light emission portion is restricted and electric power can be supplied also to a gun body. In a light emission device mounted to a gun body to emit light toward a target, a device body comprises a power supply composed of a light emission portion and a charging-type battery, and a control unit that controls emission of light, and the device body engages with option mount portions, which are provided on the gun body, to be fixed thereto by a fixation device with an optical axis of the light emission portion made substantially in agreement with a firing direction of the gun body.

Abstract: A toy or model aircraft with motions that can reproduce the operational status and flight attitude of the corresponding real aircraft. Model aircraft include a vertical motion device for enabling the aircraft body to ascend or descend in order to reproduce changes in position from a state in which the aircraft is set at a lower position so as to copy the attitude of the corresponding real aircraft during a halt on the ground to a state in which the aircraft is set at a higher position so as to copy the attitude of the corresponding real aircraft during a flight, and an attitude control device for enabling the aircraft body to be inclined in longitudinal and lateral directions in order to reproduce longitudinal and lateral motions of the rear aircraft, the attitude control device being provided at a tip portion of the vertical motion device, so that an operation performed by the vertical motion device can be synthesized with an operation performed by the attitude control device.

Abstract: The present invention provides toy or model aircraft with motions that can reproduce the operational status and flight attitude of the corresponding real aircraft.
