Japanese Patent Laid-Open No. 10-1275 (page 2, FIG. 16, FIG. 21)

  In the conventional elevator landing apparatus as described above, the portion for receiving the lower end portion of the vertical frame has a structure having only the mounting plane of the mounting bracket. In the case of an attachment with such a structure, there is a problem that if the three-way frame is installed without being locked to the upper part of the sill, the attachment may be bent due to its own weight. Further, when a spacer is inserted between the mounting bracket and the three-way frame, the entire three-side frame has to be lifted, so that there is a problem that it takes a very long time and workability is poor.

  The present invention was made to solve the above-mentioned problems of the prior art, and there is no possibility of deformation of the attachment metal when fixing the three-way frame to the sill of the elevator landing device, and the workability is good. The purpose of the present invention is to obtain an elevator landing device capable of improving the performance.

  An elevator landing apparatus according to the present invention includes a sill provided at a lower part of an elevator entrance / exit, an attachment fixed to a longitudinal end portion of a side surface portion of the sill, an upper part of the entrance / exit, and Elevator hall comprising an upper frame and a pair of vertical frames formed so as to surround three sides on the left and right side portions, and having a lower end portion of the vertical frame fixed to the sill via the mounting bracket. In the apparatus, the attachment metal is formed in a vertical direction and is fixed to the side surface portion of the sill side of the sill, and protrudes from the predetermined portion of the sill attachment portion in the direction of the landing side, and the upper surface is formed in the horizontal direction. The three-sided frame attaching portion and the upper end of the sill attaching portion can hold the lower end portion of the vertical frame formed so that the height is the same as the upper surface of the sill when attached to the sill. A frame locking portion.

  In this invention, a three-sided frame is provided at the upper end of the sill mounting portion of the mounting bracket by providing a vertical frame locking portion having a height that can hold the lower end of the vertical frame of the three-sided frame at the same height as the upper surface of the sill. At the time of mounting, by placing the lower end portion of the vertical frame on the vertical frame locking portion of the mounting bracket, the load on the mounting bracket is dispersed and deformation of the mounting bracket can be prevented. In addition, by tilting the vertical frame placed on the vertical frame locking portion, when there is a gap between the three-side frame mounting portion and the vertical frame side mounting member, adjustment for inserting the spacer is facilitated, and workability is improved. .

FIG. 6 is a reference view for explaining the operation when a conventional mounting bracket is used. In the figure, a sill 1 is provided at a lower part of a landing doorway (detailed illustration is omitted) that is a boundary part between an elevator landing and a hoistway, and a three-way side is provided on the side 1a of the landing side (right side in FIG. 1) of this sill 1. A lower end side of the vertical frame 2 constituting the frame is fixed via a mounting metal 3. The three-way frame is, for example, a known member comprising an upper frame and a pair of left and right vertical frames assembled in a U-shape so as to surround the upper part of the landing entrance and the three sides of the left and right side parts. As shown in Fig. 2, a lip groove steel is used.

  The attachment metal 3 is bent from a sill attachment part 31 that is formed in a vertical direction and is fixed to the landing side surface part 1a of the sill 1 and a predetermined part (the center part in this example) of the sill attachment part 31. The upper side of the sill attachment part 31 and the height of the three-sided frame attachment part 32 that protrudes in the direction of the landing side and is formed to be horizontally the same as the upper surface 1b of the sill. The vertical frame engaging portion 31a that can hold the lower end portion 2a of the vertical frame 2 is formed. In this example, the vertical frame is press-molded from a plate material. The three-way frame attachment portion 32 is provided to be slightly lower than the height of the vertical frame locking portion 31a, that is, the upper surface 1b of the sill 1 at the time of attachment. The sill attachment portion 31 is provided with two through holes 31b for inserting fasteners 41 made of bolts and nuts, and the lower end portion of the vertical frame 2 is fixed to the center portion of the three-way frame attachment portion 32. A through hole 32a for inserting the same fastener 42 is provided.

  On the other hand, an attachment member 6 for fixing to the attachment metal 3 is attached to the inside of the lower end portion of the vertical frame 2 by welding or the like, and the attachment member 6 is engaged with the upper surface of the three-way frame attachment portion 32. A horizontal mounting portion 61 for stopping is projected, and the mounting portion 61 is provided with a through hole 61a communicating with the through hole 32a of the three-way frame mounting portion 32. In addition, the required number of spacers 7 having a required thickness is inserted between the upper surface of the three-way frame mounting portion 32 and the mounting portion 61 as necessary. Since other configurations are the same as those of the conventional apparatus, illustration and description thereof are omitted. Note that the same reference numerals denote the same or corresponding parts throughout the drawings.

  Next, the operation of the first embodiment configured as described above will be described. In order to assemble the three-sided vertical frame 2 to the sill 1, first, the attachment metal 3 is fixed with fasteners 41 at predetermined positions on both ends in the longitudinal direction of the landing side surface portion 1 a of the sill 1. At this time, the attachment is made so that the height of the vertical frame locking portion 31 a at the upper end of the attachment metal 3 coincides with the upper surface 1 b of the sill 1. Next, the three-way frame is raised at the entrance / exit part of the elevator hall (not shown), and the attachment metal is attached so that the lower end 2a of the vertical frame 2 is engaged with the vertical frame engagement part 31a at the upper end of the attachment 3 Put on 3. At this time, the attachment portion 61 of the attachment member 6 is simultaneously placed on the three-way frame attachment portion 32, and the load on the three-way frame is dispersed. In addition, although only one side of the vertical frame 2 is illustrated, it goes without saying that the opposite side is similarly placed on the attachment metal 3.

  Next, when there is a gap or the like between the vertical frame locking portion 31a and the mounting portion 61 on the vertical frame 2 side due to tolerance or the like, the lower end 2a of the vertical frame 2 locked to the vertical frame locking portion 31a is used as a fulcrum. As shown in FIG. 4, the vertical frame 2 is rotated in the direction of the arrow A so that the upper surface of the three-way frame mounting portion 32 of the mounting bracket 3 and the lower surface of the mounting portion 61 of the mounting member 6 on the vertical frame 2 side. After the necessary spacers 7 are inserted, the vertical frame 2 is returned to the vertical position, and the attachment metal 3 and the attachment member 6 are fastened together with the fasteners 42 to complete the assembly.

  In the first embodiment configured as described above, when the vertical frame 2 is installed, the lower end of the vertical frame 2 is placed on the vertical frame locking portion 31a having the same height as the upper surface 1a of the sill 1 as shown in FIG. Since the installation is performed so that the portion 2a is applied, the attachment metal 3 is not forced and the deformation of the attachment metal 3 can be prevented. When the mounting bracket 3 does not have the vertical frame locking portion 31a, the mounting member 6 of the vertical frame 2 hits the three-way frame mounting portion 32 of the mounting bracket 3 on the sill 1 side as shown in the reference diagram of FIG. Therefore, the attachment metal 3 may be deformed.

  In addition, since the load on the three-side frame is supported by both the vertical frame locking portion 31a and the three-side frame attachment portion 32, which are projecting surfaces, the load on the attachment metal 3 can be dispersed, and permanent deformation of the attachment portion is prevented. I can do it. Furthermore, when there is a gap between the vertical frame locking part 31a and the vertical frame side mounting part 61 due to tolerances, etc., adjustment to insert a spacer is necessary, but when the mounting metal 3 does not have the vertical frame locking part 31a, In order to adjust the height of the vertical frame 2, the entire three-sided frame must be lifted, whereas in the first embodiment, the vertical frame locking portion 31 a is provided in the attachment metal 3, and as shown in FIG. By applying a load to the vertical frame locking portion 31a and inclining the three-way frame in the direction of arrow A with the lower end 2a of the vertical frame 2 as a fulcrum, the gap is easily widened, and the spacer 7 corresponding to the corrected height is easily inserted. As a result, workability is improved.
