<Embodiment 1>
FIG. 1 is a perspective view of an elevator holder device according to Embodiment 1 of the present invention. FIG. 2 is a cross-sectional view of the main part of the hold door device shown in FIG. As shown in FIG. 1, the door panel 1 opens and closes the entrance to the hall by moving in the direction of the arrow. A sill 2 is disposed below the door panel 1, and a sill groove 3 extending in the opening / closing direction of the door panel 1 is provided at the center of the sill 2 on the upper surface 2 a side. The height of the uppermost surface 2a of the sill 2 is formed higher than the height of the lower end portion of the door panel 1 with respect to the position of the lower surface (bottom surface) 2b of the sill 2.

  A slope member 4 is disposed adjacent to the sill 2 on the hall side. This slope member 4 is inclined in the direction of the hall hall, the upper face 4a having the same height as the upper face 2a of the sill 2, the lower face 4b in contact with the floor 5 of the hall, and connects the upper face 4a and the lower face 4b on the hall side. And a slope 4c. For this reason, the level | step difference of the upper surface 2a of the sill 2 and the floor surface 5 of the hall is filled up in gently sloping. A bracket 6 is welded and fixed to the wall surface 1 b on the hoistway side of the door panel 1 with a weld nut 7, and a resin guide shoe 8 is fastened and fixed to the upper end surface of the bracket 6 with screws 9.

  As shown in FIG. 2, the bracket 6 has a vertical wall 6 a and a top wall 6 b that protrudes horizontally from the upper end of the bracket 6 in a direction opposite to the door panel 1. The top wall 6 b is provided with a screw hole (not shown) penetrating in the vertical direction. A guide shoe 8 is fastened and fixed to the top wall 6 b of the bracket 6 by a pair of screws 9.

  Further, the guide shoe 8 has a slide portion 8a accommodated in the sill groove 3, and a guide shoe main body 8b for supporting the slide portion 8a in a suspended manner. The guide shoe main body 8b has a T-shaped vertical wall 10a as viewed from the front, and a top wall 10b protruding from the upper end toward the door panel 1 in the horizontal direction, and the top wall 10b has a pair of top walls 10b. A screw hole (not shown) is provided. Then, the guide shoe main body 8b has the top wall 10b placed on the upper surface side of the top wall 6b of the bracket 6, and the shaft portion of the screw 9 is passed through the long hole of the top wall 6b to form the screw hole of the bracket 6. It is fastened and fixed on the bracket 6 by tightening.

  By configuring the elevator holder device as described above, the height of the upper surface portion 2a of the sill 2 is formed higher than the lower end portion of the door panel 1, and is housed in the sill groove 3 provided below. The path to the guide shoe 8 is a bent space. Therefore, even if a fire that has occurred in the building reaches the hall, the heat from the fire is not easily transmitted from the hall to the hoistway, so the guide shoe 8 is burned out and the door panel is likely to come off. Can be prevented. Similarly, smoke generated by a fire is not easily transmitted to the hoistway side, so that passengers in the car can be safe at the same time. Furthermore, by providing the slope member 4 next to the sill 2 on the hall side, the step between the sill 2 and the floor surface 5 of the hall can be filled, and water is discharged from a sprinkler (not shown) in the event of a fire. Even if it is broken, there is an advantage that the water can be prevented from flowing into the hoistway side.

<Embodiment 2>
FIG. 3 is a cross-sectional view of an essential part of an elevator holder device according to Embodiment 2 of the present invention. In addition, since the code | symbol common with the code | symbol attached | subjected in FIG. 2 represents the same object, description is abbreviate | omitted and below demonstrates a different location in detail.

  As shown in FIG. 3, in this embodiment, in addition to the sill 2 (hereinafter referred to as “first sill”), which is an existing product, the height of the upper surface is equal to the floor of the hall. A new sill 11 (hereinafter referred to as “second sill”) is arranged on the first sill 2 and fixed to the sill 2. The second sill 11 has an upper surface 11a formed higher than the lower end surface of the door panel 1, a contact surface 11b in contact with both the floor surface 5 of the hall and the upper surface 2a of the first sill 2, and is inclined in the direction of the hall. The slope member has an inclined surface 11c that connects the upper surface 11a of the second sill 11 and the contact surface 11b on the hall side.

  As described above, according to the elevator holder device according to the present embodiment, the second sill 11 is simply added on the first sill 2 without removing the existing sill 2, and the first embodiment described above. The same effect can be achieved. For this reason, there exists an advantage which can perform a fire prevention process to a hold-a apparatus at an early stage and low cost. The door panel 1 and the guide shoe 8 can be used as they are.

<Embodiment 3>
FIG. 4 is a cross-sectional view of an essential part of an elevator holder device according to Embodiment 3 of the present invention. In addition, since the code | symbol common with the code | symbol attached | subjected in FIG. 2 represents the same object, description is abbreviate | omitted and below demonstrates a different location in detail.

  In this embodiment, the 2nd sill 11 has the protrusion part 12 formed and protruded toward the back surface 1b of the door panel 1 from the inner surface 10e by the side of a hoistway, and the sill groove 3 is formed as the bent space. . An end surface 10f in the projecting direction of the projecting portion 12 is separated from the guide shoe main body 8b and the back surface 1b of the door panel 1, and does not prevent the door panel 1 from being opened and closed. Further, the guide shoe main body 8b is also bent so as to fit in the space of the sill groove 3.

  Thus, by forming the second sill 11 and the guide shoe main body 8b, the width in the short direction of the sill groove 3 that has become longer due to the provision of the second sill 11 can be reduced. It is possible to further prevent the smoke from filling from the hall to the hoistway side. Further, since the sill structure has a shape that prevents the door panel 1 from coming off, even if the guide shoe 8 is burnt out or deformed, it is possible to prevent the door panel from coming off in the event of a fire.

<Modification>
FIG. 5 is a cross-sectional view of an essential part of an elevator holder device according to a modification of the present invention. In FIG. 5, the sill 13 having a shape in which the sill 2 and the slope member 4 shown in the first embodiment are integrated is arranged. In this case, there is an advantage that a fire prevention treatment can be easily performed by replacing the existing sill 2.

  As mentioned above, although some embodiment of this invention was described, these embodiment is shown as an example and is not intending limiting the range of invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
