1 to 3 illustrate a distance adjusting device according to Embodiment 1 of the present invention, and FIG. 1 is a perspective view showing an external configuration of an elevator car using the distance adjusting device, and shows a door as a mounting member. Shows the legs attached to the lower edge of the door. 2 is an enlarged cross-sectional view of the door leg mounting portion of FIG. 1, and FIG. 3 is an exploded perspective view of the door leg mounting portion of FIG. In the figure, a door 2 suspended from a hanger rail 11 is provided at the doorway of an elevator car 1 formed in a box shape so that the door 2 can be opened and closed. 4 is attached so that the front-rear position can be adjusted. The lower end of the door leg 3 protrudes from the lower end of the door 2 and enters the groove 12a of the sill 12, supports the lower part of the door 2 in the front-rear direction, and moves the door 2 along the sill 12 when opening and closing. To guide.

  A lower side of the reinforcing frame 21 having an L-shaped cross section, which is a mounted portion, is fixed to the lower end portion of the door 2 by welding or the like along the width direction of the door 2. The spacing adjusting device 4 is fixed to the surface of the reinforcing frame 21 facing the door leg 3 as a member to be attached by welding or the like, and the other end from the one end side (the lower side in FIG. 2 in this example). An inclined member 41 having an inclined portion 41a formed so that the part side (upper side) is close to the other side, and the inclined member 41 can be moved in the inclination direction between the inclined member 41 and the door leg 3 A wedge-shaped member 42 having an inclined surface 42a interposed between the reinforcing frame 21 and the door leg 3 by moving the wedge-shaped member 42 in the inclination direction of the inclined member 41. The adjustment bolt 43 is used.

  In this example, the inclined member 41 is a wedge-shaped block material, and two screw holes 41 b that are screwed into the screw portions of the fixing bolt 5 that is a fastener are spaced apart in the width direction of the door 2 and are screwed. In this example, the inclined surface 42a of the wedge-shaped member 42 is formed at the same inclination angle as that of the inclined member 41. The inclined surface 42a is in contact with the inclined portion 41a of the inclined member 41 in accordance with the inclination direction. The side surfaces are formed in parallel. And two long holes 42b formed long in the inclination direction (the vertical direction in FIG. 2) for inserting the fixing bolt 5 are penetrated in the mounting interval direction (the horizontal direction in FIG. 2).

  Further, a screw hole 42c that is screwed into a screw portion of an adjustment bolt 43 that is a distance adjusting member for moving the wedge-shaped member 42 in a substantially inclined direction with respect to the inclined member 41 is provided at the center of the upper end surface of the wedge-shaped member 42.

The head of the adjustment bolt 43 is locked to the upper edge of the notched slot 21 a provided on the upper side of the reinforcing frame 21 via a washer 431. Furthermore, two insertion holes 3a for inserting the fixing bolts 5 are provided in the upper part of the door legs 3 at the same intervals as the screw holes 41b.

  Next, the operation of the first embodiment configured as described above will be described. First, the inclined member 41 is fixed to a predetermined portion of the reinforcing frame 21 of the door 2 by welding or the like so that the inclined portion 41a faces the leg 3 side of the door. The inclined member 41 forms an inclined portion 41a (in this example, an inclined surface) and has a function of a mounting seat. Next, the screw hole 42c of the wedge-shaped member 42 is attached with the pulling adjustment bolt 43 with the washer 431 attached, and the inclined surface 42a is opposed to the inclined portion 41a of the inclined member 41 so that the inclination direction is matched. Then, it is inserted from the front of the notched slot 21a of the reinforcing frame 21 and is locked to the upper edge of the notched slot 21a by the head of the adjusting bolt 43, and then the fixing bolt 5 is attached to the washer 51 and the door leg. 3 and the elongated hole 42b of the wedge-shaped member 42 are sequentially inserted, and then screwed into the screw hole 41b of the inclined member 41 to be locked.

  Next, the fixing bolt 5 is lightly tightened by hand, the position of the door leg 3 in the front-rear direction (left-right direction in FIG. 2) is confirmed, and if necessary, the wedge-shaped member 42 is pulled up with the pulling adjustment bolt 43, or While pressing down, for example, the dimension L shown in FIG. 2 is adjusted, and when the front and rear positions of the door legs 3 are determined, the fixing bolts 5 are tightened to complete the installation. The adjustment bolt 43 is rotated by hand or a spanner, but is necessary because a slot 43a for a plus driver is provided in the head of the adjustment bolt 43 as shown in FIG. Thus, the adjustment bolt 43 can be turned with a Phillips screwdriver (not shown), so that an efficient operation can be performed particularly when the adjustment range is large.

As described above, according to the first embodiment, the distance adjustment such as the front / rear position adjustment of the door leg 3 with respect to the reinforcing frame 21 can be easily performed only by adjusting the adjustment bolt 43 and the fixing bolt 5. Therefore, it is not necessary to prepare an auxiliary member such as a spacer for adjusting the interval, and since the adjustment work is easy, it does not take time and the workability can be improved.
Note that the wedge-shaped member 42 having the inclined surface 42a is generally expensive in machining by a machine, but the required number of door legs 3 is a substantial number determined by the product of the number of elevators manufactured and the number of stop floors. Therefore, for example, it is possible to suppress an increase in manufacturing cost by performing mass production with a dedicated mold.

Embodiment 2. FIG.
