Title:
LOWER GUIDE STRUCTURE OF DOOR
Document Type and Number:
Japanese Patent JPH10238203
Kind Code:
A
Abstract:

To smoothly open and close a door by forming a guide groove in a lower part of the door or one of fixing members opposed to the lower part of the door, and freely longitudinally adjusting the position of a guide protrusion when the guide protrusion fitted into the guide groove is arranged in the other.

A screw shaft 27 whose axis is turned in the longitudinal direction is rotatably arranged in a casing 26 housed in the lower part of a sliding door 8 or the like. Next a pin-shaped guide protrusion 30 is protrusively arranged downward in a female screw body 29 fitted with the screw shaft 27. Next, a guide rail 34 having an upward opening guide groove 35 is fitted and installed into a pair of longitudinal fitting grooves 33 formed in a lower frame material 5, and the guide protrusion 30 is fitted into the guide groove 35 without almost longitudinal play. A door 8 warps, and the guide protrusion 30 strongly comes into contact with a front face or a rear face of the guide groove 35, and when the sliding door 8 is not smoothly opened and closed, the screw shaft 27 is rotated, and the guide protrusion 30 is moved to a position of not strongly coming into contact with front and rear surfaces of the guide groove 35. Therefore, a position of the guide protrusion can be easily adjusted, and even if the door warps, it can be smoothly opened and closed.
