(1) One Embodiment in the Present Invention FIG. 1 is a side view showing a hoistway of an elevator in which a Fescher plate according to an embodiment of the present invention is arranged. With reference to FIG. 1, the structural example of the elevator by which the Fescher plate by this Embodiment is arrange | positioned is demonstrated.

(1-1) Configuration Example of Elevator A car 1 is a car for passengers of the elevator to ride, and a counterweight 2 is a weight provided on the opposite side of the car 1 in order to move the elevator efficiently. is there. As shown in FIG. 1, a car 1 and a counterweight 2 are connected to a main rope 4 and are suspended in a slidable manner via a hoisting machine 3 that is a motor. The car 1 and the counterweight 2 move up and down along a guide rail (not shown) as the main rope 4 is wound up by the hoisting machine 3. The movement of the hoisting machine 3 is controlled by the elevator control panel 5. Accordingly, the car 1 and the counterweight 2 are driven up and down in the hoistway by the control of the elevator control panel 5.

  The car 1 is provided with a car door 6 that can be controlled to be opened and closed by a door driving device 7. When a driving force is applied from the door driving device 7, the car door 6 is provided with a door rail (not shown) formed on the upper door driving device 7 and a guide groove (not shown) formed on the lower car sill 8. Z)) can be smoothly opened and closed.

  On the other hand, a landing 10 corresponding to an elevator landing on the building side is provided with a landing door 11 that opens and closes when the car 1 gets on and off. The landing door 11 smoothly opens and closes along a door rail (not shown) formed on the upper header 12 and a guide groove (not shown) formed on the lower landing sill 13. The opening / closing operation of the landing door 11 is controlled in conjunction with the opening / closing operation of the car door 6 by the car door driving device 7. In addition, a toe guard 14 that is a protective plate for preventing the user from falling is provided in the vertical direction below the landing threshold 13.

  The fisher plate 15 is a plate-like member that is installed to ensure the safety of the user. As described above, the car 1 moves up and down in the hoistway according to the control of the elevator control panel 5, but when an accident such as an earthquake or a fire occurs, the car 1 stops between the floors, or even the car doors between the floors. 6 may open. In such a case, if the horizontal distance between the hoistway wall 9 and the facing hoistway wall 9 is too large, the user may fall from the car 1, in order to prevent such a fall risk. A Fescher plate 15 is arranged at a position closer to the car sill 8 than the hoistway wall 9. For example, when the gap of the horizontal distance between the tip of the car sill 8 and the hoistway wall 9 (showing the wall surface in the hoistway) facing the car exceeds 125 mm, and the vertical between the lower end of the toe guard 14 and the upper end of the header 12 When the distance gap exceeds 38 mm, the Fescher plate 15 is installed between the toe guard 14 and the header 12. The number of the Fesher plates 15 to be arranged may be determined based on the distance between the toe guard 14 and the header 12. The fisher plate 15 and the header 12 are fixed via a header upper bracket 16, and the fisher plates 15 are fixed to each other via an intermediate bracket 17 fixed to the hoistway wall 9. Further, the toe guard 14 and the fisher plate 15 may be fixed via the intermediate bracket 17 in the same manner as the connection between the fisher plates 15.

(1-2) Basic Configuration of Fesher Plate Hereinafter, the fascia plate 15 according to the present embodiment will be described in detail. As described above, the Fescher plate 15 is a member that is installed for the purpose of preventing the user from falling from the car 1, and therefore has a strength of a certain level or more (for example, an area of 5 cm 2 at an arbitrary position of 300 N). It is required to have a deflection of 15 mm or less when an equally distributed load is applied vertically. The Fescher plate 15 has a plate-like surface, and is provided on the hoistway wall 9 so that the plate-like surface is parallel to the moving direction of the elevator car 1 (vertical direction in FIG. 1). It is fixed to a fixing member (corresponding to the intermediate bracket 17).

  In general, as one method of ensuring the strength of the Fescher plate, a method of increasing the thickness (plate thickness) of a metal plate used for the Fescher plate is conceivable. While this method can increase the strength, the weight of the fisher plate is surely increased by the thickness of the plate, which not only increases the workload during assembly work on site, but also transports to the site. The burden is also increased in terms of labor and transportation costs. As another method, there is a method in which the strength is increased by performing processing such as rib forming on the metal plate of the Fescher plate. However, this method not only has a problem that the processing cost increases when a complicated molding process is performed in advance, but also when the strength is increased when the predetermined strength is not obtained even when the rib is formed. Therefore, the same problem as described above exists. From such a side, the Fescher plate 15 according to the present embodiment employs a method of reinforcing by providing a reinforcing material on the back surface.

  The Fescher plate 15 according to the present embodiment includes a plate-shaped main material 21 and a “U” -shaped reinforcing material 22. The main material 21 is obtained by subjecting a plate-like member similar to a conventional fisher plate not reinforced by a reinforcing material to a shape processing unique to the present embodiment, and having a certain level of strength or more. Etc. are preferably used. The shapes of the main material 21 and the reinforcing material 22 will be described later with reference to FIGS. 2 and 3. Each component (main material 21 and reinforcing material 22) of the fescher plate 15 can be packed and transported separately during transportation, and the reinforcing material 22 can be attached to the main material 21 during installation on the hoistway. Features.

  FIG. 2 is a view showing the Fescher plate (main material) from the front or from above. As shown in FIG. 2, the main material 21 has a shape in which both side end portions of a rectangular plate-like member are bent, and a reinforcing material 22 (an insertion portion 22a described later) is attached near the upper end in the front view. An attachment hole 21b is formed as a notch hole for the purpose, and an attachment hole 21a is formed near the lower end as a notch hole for attaching the reinforcing member 22 (insertion portion 22b described later). The vertical width (height) of the cutout holes in the attachment holes 21a and 21b is formed so that the attachment hole 21a is higher than the attachment hole 21b.

  FIG. 3 is a view showing the reinforcing material from the front, from above, or from the side. As shown in FIG. 3, the reinforcing member 22 has a shape in which each side portion of a rectangular plate-like member is bent into a lid shape. In the front view, the insertion portion 22 a formed above the reinforcing member 22 is a portion to be inserted into the mounting hole 21 b of the main material 21, and the insertion portion 22 b formed below the reinforcing member 22 is the portion of the main material 21. It is a part inserted in the attachment hole 21a. The insertion portions 22a and 22b are provided with stepped portions 22c and 22d for securing a step in consideration of the plate thickness of the main material 21 and the reinforcing material 22. By providing such stepped portions 22c and 22d, it is possible to prevent an excessive load from being applied to the contact portion when the reinforcing material 22 is attached to the main material 21. The vertical length of the insertion portions 22a and 22b is formed so that the insertion portion 22a is longer than the insertion portion 22b.

  FIG. 4 is a diagram for explaining a procedure for attaching a reinforcing material to the Fescher plate (main material). First, as shown in FIG. 4A, the insertion portion 22 a of the reinforcing material 22 is inserted into the attachment hole 21 b of the main material 21. Next, as shown in FIG. 4B, the reinforcing member 22 is rotated so as to overlap the main member 21, and the insertion portion 22b is inserted into the attachment hole 21a. Finally, as shown in FIG. 4C, while fixing the main material 21 so as not to move, the reinforcing material 22 is placed until the lower portions of the stepped portions 23d and 23c hit the lower portions of the mounting holes 21a and 21b, respectively. Slide downward in the figure. The sliding reinforcing member 22 is connected to the main member 21 at a predetermined position.

  By performing a series of procedures as shown in FIG. 4, the reinforcing plate 22 can be attached to the main member 21 without using a tool, thereby completing the Fescher plate 15. FIG. 5 is a view showing the Fescher plate to which the reinforcing material is attached from the front, the lower side or the side. The Fescher plate 15 shown in FIG. 5 is installed on the hoistway wall 9 so that the attachment hole 21b is upward and the attachment hole 21a is downward. As a result, since the reinforcing member 22 is pulled downward by gravity (self-weight) applied to itself in the fisher plate 15, there is no possibility of falling without being fastened to the main member 21. That is, the reinforcing material 22 can be attached so as not to fall off the main material 21 after the attachment.

(1-3) Production Examples of Abutting Portions in Main Material and Reinforcing Material Note that there are various production examples of the main material 21 and the reinforcing material 22 constituting the Fescher plate 15 by paying attention to the abutting portions. Conceivable. As an example, a manufacturing example of the main material 21 will be described with reference to FIGS. 6 and 7, and a manufacturing example of the reinforcing material 22 will be described with reference to FIGS. 8 and 9.

  FIG. 6 is a diagram for explaining a pattern of cutout holes in the Fescher plate (main material). FIG. 7 is a detailed view of the abutting portion of the Fescher plate to which the reinforcing material is attached. FIG. 6A is a view showing the main material 21 from the front, and FIGS. 6B to 6D are views of the main material 21 with notched patterns having different shapes, respectively. It is sectional drawing along the AB line.

  And the main material 21B shown by FIG.6 (b) becomes a shape which notched the part of the attachment holes 21a and 21b similarly to the main material 21 demonstrated in FIGS. 2-5. . FIG. 7A is an enlarged view of the vicinity of the attachment hole 21a in a state where the reinforcing material 22 is attached to the main material 21B. A width d1 illustrated in FIG. 7A is a width of a space generated when the insertion portion 22b of the reinforcing member 22 is attached to the attachment hole 21a.

  Next, the main material 21C shown in FIG. 6C covers the insertion portions 22b and 22a when the insertion portions 22b and 22a of the reinforcing material 22 are inserted into the back side of the attachment holes 21a and 21b. It has a shape provided with a simple cover. FIG. 7B is an enlarged view of the vicinity of the attachment hole 21a in a state where the reinforcing material 22 is attached to the main material 21C, and the width d2 shown in FIG. 7B is reinforced to the attachment hole 21a. This is the width of the space generated when the insertion portion 22b of the material 22 is attached. At this time, the width d2 is smaller than the width d1 shown in FIG.

  Therefore, it can be seen from the comparison of the widths d1 and d2 that the shape of the main material 21C can suppress the degree of strength reduction due to the space cut out for the mounting hole 21a, compared to the shape of the main material 21B. For example, the strength of the entire Fescher plate 15 against the force from the horizontal direction can be improved. Further, in the main material 21D shown in FIG. 6 (d), a cover is provided on the back side of the mounting holes 21a and 21b so as to be more closely attached to the insertion portions 22b and 22a of the inserted reinforcing material 22. The degree of strength reduction due to the notch space is suppressed more than that of the main material 21C, and the strength of the entire Fescher plate 15 against vertical load can be further improved.

  FIG. 8 is a diagram illustrating an example of a fixed state between the intermediate bracket and the fescher plate. As described in (1-1), the intermediate bracket 17 is a member that fixes the fisher plate 15 to the hoistway wall 9 by fixing the upper end portion, the lower end portion, or both of the fisher plate 15. Therefore, a general fixing mounting bracket or the like can be used. The fisher plate 15 is fixed to the intermediate bracket 17 by fixing a part of the main material 21 of the fisher plate 15 to the intermediate bracket 17 as shown in FIG. The strength of the fisher plate 15 shown in FIG. 8 is improved by attaching the reinforcing material 22 to the main material 21. When force is applied to the Fescher plate 15 from the horizontal direction in the drawing, the vertical load applied to the Fescher plate 15 is transmitted to the hoistway wall 9 side from the fixed portion of the main material 21 to the intermediate bracket 17. .

  FIG. 9 is a diagram showing another example in a fixed state between the intermediate bracket and the Fescher plate. The fascia plate 15 shown in FIG. 9 facilitates transmission of a vertical load to the intermediate bracket 17 when a force is applied to the fescher plate 15 from the horizontal direction in the drawing, and the burden on the fescher plate 15 is reduced. Ingenuity for reduction is made. More specifically, as shown in FIG. 9, the length of the reinforcing member 22 with respect to the fascia plate 15 is longer than that of the reinforcing member 22 shown in FIG. 8, and as a result, is fixed to the intermediate bracket 17. In the portion, the insertion portion 22a (or 22b) overlaps the intermediate bracket 17 with the main material 21 interposed therebetween. According to the Fescher plate 15 using the reinforcing material 22 that can constitute such a positional relationship, when a force is applied from the horizontal direction in the drawing, the vertical load applied to the Fescher plate 15 is inserted into the insertion part of the reinforcing material 22. Since it is transmitted to the intermediate bracket 17 via 22a and 22b, compared with the case shown in FIG. 8, the burden concerning the Fescher plate 15 can be reduced. Further, by reducing the burden on the fisher plate 15, it is expected that the bending that may occur in the fisher plate 15 is reduced and the relative strength of the fisher plate 15 with respect to the force from the horizontal direction is improved. it can.

At the same time, since the main material 21 and the reinforcing material 22 can be packed separately at the time of packing, the transportation efficiency can be improved, and the transportation cost can be expected to be reduced. Moreover, since the main material 21 and the reinforcing material 22 can be packed separately, the effect of space saving in the storage place of materials can also be expected.

  Further, according to the Fescher plate 15 according to the present embodiment, the Fesher plate 15 can be assembled by attaching the reinforcing material 22 to the main material 21 without a tool according to the procedure as shown in FIG. Work can be done easily and reliably. In addition, since an attachment part for attaching and fixing the reinforcing material 22 to the main material 21 is not necessary, an effect of eliminating the possibility of installation failure due to a failure of the attachment part can be expected.
