PROBLEM TO BE SOLVED: To easily and properly make positional adjustment of a striker caught by a receiving member. SOLUTION: An assisting mechanism comprises the striker 4 installed on a door Ma and a receiving member 1 which is installed in a door frame Fa, moves after catching the striker 4 at a specified outward movement position of the door Ma and assists outward movement of the door Ma to a closing position. The striker 4 is supported on a striker base 5 having an attaching part 5a to the door Ma, in the state of permitting adjustment of a supporting position by an adjusting means 6 in a direction approximately conforming to the turning direction x of the door Ma.

PROBLEM TO BE SOLVED: To provide a slide assistance mechanism which is further simplified as a restoring structure. SOLUTION: The slide assistance mechanism includes a case 1 attached to either of a body 7 or a moving body A, a latch 4 arranged movably in the case and shifting between a standby attitude wherein the latch is engaged in the case and a pull-in attitude wherein the engagement is released, an energizing means 3 for urging the latch in one direction and an operating member 8 mounted in other of the body 7 or the moving body. When the latch 4 is shifted from the standby attitude to the pull-in attitude, the moving body can be moved with a help of the energizing force accumulated in the energizing means from a first position to a second position on the body side via the operating member 8. The main part includes an engagement part 42 in a normal time for engaging with the operating member 8 working in conjunction with the shift of the latch 4 from the standby attitude to the pull-in attitude, and also a subsidiary engagement means 47 for releasably engaging the operating member 8 when the operating member in a disengaging condition with the engagement part is in the pull-in attitude.

PROBLEM TO BE SOLVED: To provide a window opening/closing device which can bring the force of movement of a sash toward an opening-opened position close to a fixed level. SOLUTION: This window opening/closing device 1 comprises: a window frame 2 which is mounted on a building; the sash 4 which is arranged in the opening 3 defined in the window frame 2 and which opens/closes the opening 3; a connecting means 32 which makes an upside portion 31 in vertical direction V of the sash 4 turnably connected to the window frame 2 so that the sash 4 can make the opening 3 freely openable/closable on the basis of an airflow; and an urging means 5 which is connected to the sash 4 and the window frame 2 so as to urge the sash toward the opening-closed position. The opening 3 is opened by the opening-opening movement of the sash 4 toward the outside 7 of the building, and closed by the opening-closing movement of the sash 4 toward the inside 8 of the building.

PROBLEM TO BE SOLVED: To restrain the swing and the idle motion of a sliding door by an impact or vibration from an operator cab, in a fully opening state of the sliding door installed in the operator cab. SOLUTION: The swing and the idle motion are restrained by an upper rail 4 and a lower rail 5 formed in an upper part and a lower part of an outside wall for opening an entrance, the sliding door 3 opening and closing the entrance by an upper roller and a lower roller engaged with the upper rail 4 and the lower rail 5, a pad formed in an upper bracket for installing the upper roller, a pad formed in a lower bracket for installing the lower roller, an upper stopper 21 preventing the swing of the sliding door 3 by the pressurization of the pad in an opening position for completely opening the sliding door, and a lower stopper 23 arranged on the outside wall of the opening position for completely opening the sliding door 3 and preventing the swing of the sliding door by the pressurization of the pad.

Abstract:
PROBLEM TO BE SOLVED: To provide a braking device of a sliding door capable of simplifying a structure of the braking device of the sliding door because it takes time before braking begins to be effective in the case damping force is made to occur by oil pressure, because there is such a problem that the damping force is varied by an open air temperature and because there is such a problem or the like that a rack has to be provided over the overall length of braking section. SOLUTION: When the sliding door (1) suspended on a rail (2) fixed to the upper part of a door frame through a sheave (3) approaches a closing position or an opening position, in the breaking device of the sliding door so as to add the damping force to the sliding door by pushing the damping body (8) against at least one of a rest section (2) and the sheave, the braking body is rotatably suspended on the sliding door through an axis (10), a guiding means (9) is provided forward in the direction of the advancement of the sliding door, and when the sliding door approaches its closing position or opening position to bring the braking body into contact with the guiding means, the braking body is guided to the opposite direction to the direction of the advancement of the sheave on the axis to rotate so that it can be slidingly contacted to at least one of the rest section and the sheave.
