  However, in the former door support device, the door frame side member and the door side member are fixed to the door frame and the door, respectively, and the pin of the door side member is located at the approximate center in the thickness direction of the door. The degree of freedom of installation is small, and it can be used only for limited doors. On the other hand, in the latter door support device, since the pin position for supporting the door is away from the door, the door may be displaced or deformed unless sufficient strength is taken into consideration.

  An object of the present invention is that the door is not misaligned and the door support device is not deformed during the use of the door, that it is possible to maintain a good opening and closing, and that the door installation work is simple.

  In order to solve the above-described problems, the present invention provides a door frame having an upper frame and left and right vertical frames and a door provided in an opening formed by a floor. A support device for a door to be supported by a support, wherein the lower door support device for supporting the lower portion of the door includes a lower door side member fixed to the door side, and a floor side member fixed to the floor side. Is provided.

  By doing so, the weight of the door is mainly supported by the lower door support device. The lower door support device is formed of a lower door side member and a floor side member, but the weight of the door is transmitted from the lower door side member to the floor side member. At the same time, a reaction force is applied from the vertical pin of the floor side member to the door side. The reaction force applied from the vertical pin to the door can be broken down into a vertical reaction force and a couple moment. The vertical reaction force is transmitted from the vertical pin of the floor side member to the mounting piece via the block, the shaft-like member, the pair of side pieces, and the standing piece, and balances the weight of the door.

  The moment of couple is a magnitude obtained by applying a vertical reaction force to the horizontal distance between the center line of the vertical pin and the vertical line passing through the center of gravity of the door, and acts to rotate the door side member at the lower part of the door. However, this door side member has its mounting piece fixed to the lower end lip of the door, and the standing piece abuts against the surface of the door, so that the moment of the couple is received by the door surface and the lower end lip. Thus, sufficient strength is secured to receive the moment of the couple, and the door is stably supported.

Pin supported by pins.

  The lower door side member is mainly formed of a mounting piece, a standing piece, a pair of side pieces, a shaft-like member and a block, and a pin hole into which a vertical pin of a floor side member is rotatably fitted in the lower end surface of the block Is provided. In this case, the block may be moved and adjusted in the horizontal direction by a horizontal adjustment mechanism that can move and adjust in the horizontal direction parallel to the door surface. Further, it is preferable that the block can be moved up and down with respect to the vertical pin by an up and down direction adjusting mechanism that can move and adjust up and down.

  The upper door side member is also mainly formed by an attachment piece, a standing piece, a pair of side pieces, a shaft-like member, and a block. Further, it is preferable that a vertical through hole is provided in the block, a pin is inserted into the through hole, and the block is rotatably inserted into the pin hole formed in the upper frame side member. In this case, the block may be moved and adjusted in the horizontal direction by a horizontal adjustment mechanism that can move and adjust in the horizontal direction parallel to the door surface. Furthermore, the pin may be biased upward and may be removed from the pin hole of the upper frame side member by pulling the pin downward if necessary.

  The horizontal direction adjusting mechanism at the upper part of the door and the horizontal direction adjusting mechanism at the lower part of the door may be the same mechanism. The upper horizontal adjustment mechanism or the lower horizontal adjustment mechanism is not particularly limited. For example, a screw feed mechanism that combines male and female screws, a mechanism that changes rotational movement to linear movement by a rack and pinion, or an eccentric cam mechanism that linearizes rotational movement. A mechanism for changing movement can be used. The vertical adjustment mechanism for the door-side member at the lower part of the door is not particularly limited, but may be the screw feed mechanism, a mechanism using a rack and pinion, an eccentric cam mechanism, or the like.
