Japanese Patent No. 3290601

  By the way, in an elevator, the size reduction of a hoistway is strongly desired from the viewpoint of construction cost and utilization of building space. The hoistway houses and arranges necessary equipment and equipment in addition to the car, and the car is provided with necessary structural members and functional parts outside the car room. ing. In particular, a plurality of members called vertical reinforcing members extending in the vertical direction are attached to the outer surface of the panel that defines the cage, and these vertical reinforcing members contribute to securing the necessary strength of the panel. For this reason, in order to realize the size reduction of the hoistway without downsizing / omitting functional members / parts, it can be considered that reducing the size of the car room space is an effective measure. On the other hand, however, reducing the space in the car can cause another problem that the transport efficiency is lowered and a user may have a cramped impression.

  The present invention has been made in view of the above, and an object of the present invention is to provide an elevator cab structure that can reduce the hoistway size without greatly reducing the conveyance efficiency.

  The present invention for achieving the above-described object is an elevator cab structure configured by joining a plurality of component panels, and at least one of the plurality of component panels is a concave panel, The concave panel includes a design surface, a pair of left and right adjacent panel joint surfaces, and a handrail portion, and the pair of adjacent panel joint surfaces are more cab than the design surface in the thickness direction of the single concave panel. It is located inside, and the handrail portion protrudes from the design surface to the car room side on the car room side of the design surface.

  According to the elevator cab structure of the present invention, the size of the hoistway can be reduced without greatly reducing the conveyance efficiency.

  Embodiments of an elevator cab structure according to the present invention will be described below with reference to the accompanying drawings. In the drawings, the same reference numerals indicate the same or corresponding parts.

Embodiment 1 FIG.
As a first embodiment of the present invention, an example of a rectangular cage having a plan view and having at least three sides of both side walls and a rear wall will be described. FIG. 1 is a plan view schematically showing an elevator cab structure according to Embodiment 1 of the present invention, and FIG. 2 is a view of the cab interior of the elevator cab structure according to Embodiment 1 as viewed from an entrance. FIG. 3 is a perspective view showing one panel of the elevator cab structure according to the first embodiment.

  The elevator cab structure 1 is constituted by joining a plurality of constituent panels, and among the both side walls and the rear wall of the cab 3, each side wall is constituted by one concave panel 5. Is composed of two non-concave panels 7. In the first embodiment, most of both the concave panel 5 and the non-concave panel 7 are formed by bending and bending a metal plate member.

  As shown in FIG. 3, the concave panel 5 includes a design surface 9, a pair of left and right adjacent panel joint surfaces 11, and a handrail portion 13. The pair of adjacent panel joining surfaces 11 are located on the interior side of the cab 3 relative to the design surface 9 when viewed in the thickness direction X of the single concave panel as shown in FIG. In addition, the code | symbol X, Y, and Z of FIG. 3 has each shown the thickness direction, the height direction, and the left-right direction which looked at the concave panel single-piece | unit.

  The handrail portion 13 protrudes from the design surface 9 toward the car room side on the car room side of the design surface 9. FIG. 4 shows a configuration example of the handrail portion. As shown in FIG. 4A, the handrail portion 13 may be configured by attaching the component member 15 a to the design surface 9 by welding as a first example. Alternatively, as a second example, as shown in FIG. 4B, when the upper and lower divided panel portions constituting the design surface 9 are coupled with the bolts 17, the coupling members 15b sandwich the coupling portions. Alternatively, the configuration may be such that the handrail portion 13 is obtained by connecting the component member 15b and the two panel portions with the bolts 17. Further, as a third example, as shown in FIG. 4C, when the upper and lower divided type panel portions constituting the design surface 9 are coupled with the bolts 17, the component member 15c is combined into two panel portions. The handrail part 13 may be obtained by inserting the component member 15c and the two panel portions with the bolt 17 in advance.

  The recessed panel 5 further includes a pair of left and right thickness forming surfaces 19. Each of the thickness forming surfaces 19 rises in the thickness direction X from the design surface 9. Each edge of the thickness forming surface 19 is connected to the corresponding left and right edges of the design surface 9, and each other edge of the thickness forming surface 19 is connected to one end of the adjacent panel joining surface 11. Further, a folded surface 21 extends from the other end of the adjacent panel joining surface 11 toward the outdoor side of the cab 3.

  The thickness forming surface 19 rises at a right angle from the design surface 9, the adjacent panel joining surface 11 extends from the thickness forming surface 19 at a right angle and the corresponding left and right outer sides, and the folded surface 21 is perpendicular to the adjacent panel joining surface 11. And it extends outside the car room. Therefore, the design surface 9 and the pair of adjacent panel joining surfaces 11 are parallel, and the pair of thickness forming surfaces 19 and the pair of folded surfaces 21 are parallel.

  Next, the operation of the elevator cab structure constructed as described above will be described using a comparative example. 5, FIG. 6, and FIG. 7 are diagrams of the same mode as FIG. 1, FIG. 2, and FIG.

  As best shown in FIG. 1, each rear wall side of the recessed panel 5 is joined to a corresponding non-recessed panel 7. This is because the adjacent panel joint surface 11 is joined to the corresponding portion of the non-concave panel 7 by a bolt or the like (not shown) penetrating the fastener through hole 23 formed in each adjacent panel joint surface 11. The configuration of the non-concave panel 7 may be the same as that shown in FIG. With such joining, as shown in FIG. 1, the design surface 9 of the non-concave panel 7 and the corresponding pair of thickness forming surfaces 19 of the pair of left and right concave panels 5 are formed on the rear surface of the cab 3. Are parallel and almost flush. That is, the thickness forming surface 19 in the concave panel 5 constitutes the same surface (the rear surface of the cab) as the design surface 9 of the non-concave panel 7 which is an adjacent component panel in the cab. In addition, as a frontage dimension of the car room 3, a frontage space A which is a space between the design surfaces 9 on both side walls is secured, and the width of the elevator car room structure 1 itself is also excluded from the thickness of the design surface 9. In this case, it is caused by the frontage A.

  On the other hand, in the configuration of the comparative example, both the side walls and the rear wall of the cab are all configured by the non-concave panel 7. Each of the non-concave panels 7 has an adjacent panel joining surface 11 ′ at a portion on the left and right outermost side of the design surface 9 or at a portion outside the cab relative to the design surface 9. A reinforcing member 25 is attached to a portion of the cab outside the design surface 9. Therefore, as can be seen from FIG. 5, if the frontage A which is the distance between the design surfaces 9 on both side walls is set as in the first embodiment (as shown in FIG. 1), the elevator cab structure Is a dimension obtained by adding two dimensions A ′ to the frontage A (A ′ + A + A ′). That is, in the configuration of the comparative example, the width of the cab structure is a width that is wider than that of the first embodiment by an amount corresponding to the presence of the adjacent panel joint surface 11 ′ or the vertical reinforcing member 25 on each of the left and right sides. .

  As can be seen from the above comparison, in the first embodiment, by using concave panels on both side walls of the cab, while securing a frontage A having the same size as the frontage of the cab in the case of using a non-concave panel. However, the advantage that the width | variety of the cab structure 1 itself can be reduced rather than the case where a non-concave type panel is used is acquired. In addition, while obtaining such advantages, it is possible to ensure the necessary strength as before by including a handrail part that bridges the pair of left and right thickness forming surfaces on the indoor side of the design surface in the concave panel It has become. Thus, according to the elevator cab structure of the first embodiment, it is possible to reduce the hoistway size without greatly reducing the conveyance efficiency.

Embodiment 2. FIG.
Next, a second embodiment of the present invention will be described with reference to FIG. FIG. 8 is a diagram of the same mode as FIG. 1 regarding the second embodiment of the present invention.

  In the second embodiment, the application modes in the width direction (right and left right) and the depth direction (front and rear direction) of the cab 3 are reversed in the first embodiment. That is, in Embodiment 1 above, of the both side walls and rear wall of the cab 3, both side walls are constituted by the concave panel 5 and the rear wall is constituted by the non-concave panel 7. In the second embodiment, of the both side walls and the rear wall of the cab 3, only one concave panel 5 is used for the rear wall, and both side walls are constituted by a plurality of non-concave panels 7.

  As shown in FIG. 8, the adjacent panel joint surfaces 11 on both the left and right sides of the concave panel 5 as the rear wall are connected to the adjacent panel joint surfaces 11 ′ of the corresponding non-concave panel 7. And the thickness formation surface 19 in the concave panel 5 will comprise the same surface (cage room side surface) as the design surface 9 of the non-concave panel 7 which is an adjacent component panel in a cage | basket | car room. Therefore, as the depth dimension of the cab 3, after determining the depth of the cab structure 1 itself of the elevator while securing the depth B by the distance between the front surface of the cab and the design surface 9 of the concave panel 5 which is the rear wall. The end position is attributed to the rear end position of the depth B except for the thickness of the design surface 9.

  As described above, the second embodiment can provide the same advantages as those of the first embodiment. That is, the strength of the elevator cab structure is ensured as before, and the transport efficiency is greatly reduced. And the size of the hoistway can be reduced.

Embodiment 3 FIG.
Next, a third embodiment of the present invention will be described with reference to FIG. FIG. 9 is a diagram of the same mode as FIG. 1 regarding the third embodiment of the present invention. The third embodiment is an aspect in which both the side walls and the rear wall of the cab 3 are configured only by the concave panel 5. As shown in FIG. 9, the configuration is such that the thickness forming surface 19 of the concave panel 5 forms the same surface as the adjacent panel joining surface 11 of the adjacent concave panel 5 in the cage (substantially flush with each other). It is obtained by arranging.

  Thereby, in this Embodiment 3, the effect | action of the said Embodiment 1 is acquired regarding the both-sides wall of the cab 3, and the effect | action of said Embodiment 2 is acquired regarding the rear wall of the cab 3. That is, the effect of using the concave panel 5 is obtained on the three surfaces of the side wall and the rear wall of the cab 3.

  Also in the third embodiment, as in the first and second embodiments, the strength of the elevator cab structure is ensured as before, and the hoistway size can be reduced without greatly reducing the conveyance efficiency. It is possible to plan.

  Although the contents of the present invention have been specifically described with reference to the preferred embodiments, various modifications can be made by those skilled in the art based on the basic technical idea and teachings of the present invention. It is self-explanatory.
