摘要： PROBLEM TO BE SOLVED: To improve the slide opening/closing operability of a door without causing a support roller to slide laterally by supporting the dead weight of the door by a lower support roller in a lateral moving path and switching it into the support state by the upper support roller in draw-in moving path in opening/closing the door. SOLUTION: A door 3 moves along a lateral moving part from the rear to the front with the dead weight of the door 3 supported by a lower support roller 33 and a center support roller in opening/closing the door 3. When switching the moving direction from the lateral moving path in the direction along a draw-in moving path, the support state is switched into the one by an upper support roller 13 and the center support roller. In this case, the lower support roller 33 and the upper support roller 13 move on a horizontal support face 36a of the lower guide rail 5 and the support plate 15 of the upper guide rail 4 in order without causing the lateral sliding respectively. This constitution can move the door 3 can smoothly be moved without requiring an excessive operating force.

摘要： PROBLEM TO BE SOLVED: To provide an upper support mechanism for sliding door capable of smoothly opening and closing a slide door without clattering. SOLUTION: This sliding door device for construction machinery comprises upper and lower guide rollers at upper and lower edge parts and is slidably set in an interior doorway. The upper guide roller has a first rolling roller 16b-1 having substantially vertical rolling shaft and a second rolling roller 16b-2 having a substantially horizontal rolling shaft, and the second rolling roller 16b-2 is arranged so as to be supported by an upper guide part 19 and rolled. According to such a structure, the weight of the sliding door is almost supported by an upper guide rail part 19, and hence, a smooth opening and closing operation can be realized. When the first rolling roller 16b-1 is nipped and guided from both sides by a part of the upper guide rail part 19, the clattering in opening and closing operation or traveling can be eliminated.

摘要： PROBLEM TO BE SOLVED: To provide the supporting mechanism of a sliding door, in which soil is difficult to form in a lower-end rail section easy to most soil in a sliding-door open- close section and which is operated smoothly without shaking even when large load is locally applied in the case of the operation of the sliding door. SOLUTION: The supporting mechanism of the sliding door has upper-lower rails 19b, 20 extending along the upper-lower edge sections of an indoor entrance while guide rollers 16b-1, 16b-2 are installed at least the front-end upper-lower end sections of the sliding door 16 respectively. The lower rail 20 is composed of one slender plate- shaped rail in which a lower edge is formed in a free edge, a lower guide roller 16e comprises a roller in which two or more are paired, and the lower rail 20 is pinched and supported rotatably from a lower section by the lower guide roller 16e in which two or more are paired. Accordingly, even when partial external force works and slight deformation is formed in the case of the opening and closing of the sliding door 16, the sliding door can be opened and closed smoothly without shaking. Since there is no place, where soil and sand or the like collect, in the disposing section of the lower rail 20, soil and sand do no fill in the rail even by usage for a prolonged term, and smooth open-close operation is ensured.

摘要： PROBLEM TO BE SOLVED: To provide a double sliding window which can avoid the interference with a peripheral equipment and members, and arbitrarily opened/closed even when such a window is formed of a specially curved surface. SOLUTION: The whole section of this double sliding window is formed of an outwardly swollen arc-like surface, a three-dimensional curved surface area whose forward part is curved inward gradually upward, and a two-dimensional curved surface area (a cylindrical surface) having the same radius of curvature in the vertical direction are continuously formed on a part of thereof, and the double sliding window is mounted over the three-dimensional curved surface area and the two-dimensional curved surface area. This double sliding window comprises window sashes 22 and first and second transparent plates 23, 24 fitted to the sashes 22, the first transparent plate 23 has the three-dimensional curved surface, and fixed to the window sash 23, a forward edge part of the second transparent plate 24 overlaps a rear edge part of the first transparent plate 23, is arranged between a rear end of the window sash 22 and the first transparent plate, and comprises a part of a cylindrical body having the radius of curvature substantially same as that of the two-dimensional curved surface area. The second transparent plate 24 is guided by the window sash 22, and openable/closable smoothly in the longitudinal direction substantially without interference with the three- dimensional curved surface of the first transparent plate 23.
