Description

  The present invention relates to a technology of an elevator apparatus, and more particularly, to an elevator car having an improved connection structure of side plates constituting a wall surface of the car, and an elevator apparatus using the elevator car.

  An elevator car (sometimes simply referred to as a “car”) has a wall surface formed by connecting a plurality of car room side plates (sometimes simply referred to as “side plates”). The wall surface of the car formed by connecting the side plates has a structure in which the connecting holes and the like between the side plates are not exposed to the inside of the car room with priority on design.

  For this reason, the side plate connection work has been conventionally performed by fastening bolts and nuts outside the car room, but it is a work in a narrow space (space between the car and the hoistway wall) and is difficult to reach. Since it was concluded at the position, it was a task that was never easy. In addition, the scaffolding is unstable due to work in a narrow space, and there may be a mistake that bolts and tools are dropped into the hoistway during the work.

  Thus, various elevator cars have been studied that eliminate such difficulty in work and allow easy and safe side plate connection work. For example, in Patent Document 1 (Japanese Patent Application Laid-Open No. 11-349261), a plurality of side plates having bent portions in a direction perpendicular to the car interior surface are used on the wall surface of an elevator car, and the vicinity of the bent portions of adjacent side plates is used. In an elevator car connected in contact with each other, there has been proposed an elevator car characterized by comprising a main member for engaging the side plate connecting portion structure in the vicinity of a bent portion of the side plate and a fastening force generating member. Yes.

  Patent Document 2 (Japanese Patent Laid-Open No. 2013-163433) discloses a main surface that forms an inner wall of a cab, an end surface that is formed by bending both side ends of the main surface toward the outside of the cab, and A plurality of side plates having a folded surface parallel to the main surface and arranged such that the end surfaces are in contact with each other, and of these side plates, the first of the first and second side plates arranged adjacent to each other An opening formed across the end surface and the folded surface of the side plate, a fixed portion fixed to the folded surface of the second side plate, and an L-shape having a predetermined gap with respect to the end surface of the second side plate A connecting hook portion that is bent in a vertical direction with a predetermined gap between the second side plate and the end surface of the second side plate, and the connecting hook portion is inserted into the opening. A plate-like connecting member and the second side plate adjacent to the connecting member; A fixed portion fixed to the folded surface and a pressing piece bent into an L shape with a predetermined gap with respect to the end surface of the second side plate, and the pressing piece is inserted into the opening. A plate-like pressing member, and the connecting member is formed so as to sandwich the first side plate end surface portion between the connecting hook portion and an end surface of the second side plate, An elevator car is proposed in which the pressing member is formed to abut against the back surface of the first side plate end surface portion and press the end surface portion against the end surface portion of the other side plate. ing.

Standards have been established in each country for the mechanical strength of elevator car walls. For example, in the European standard (EN standard), there is no permanent deformation of more than 1 mm and elastic deformation of more than 15 mm when a load of 300 N is applied to an area of 5 cm ² on the car wall. Furthermore, it is specified that there is no permanent deformation exceeding 1 mm when a load of 1000 N is applied to an area of 100 cm ² . In addition, “permanent deformation exceeding 1 mm” includes a deviation at a joint portion between the side plates.

  Each side plate is usually formed into a “U-shape” like a channel material at each end, and the mechanical strength as a single side plate is ensured. However, the previous standard is applied to the entire wall surface of the car room, and not only the side plate alone but also the connection strength between the side plates is important.

  It is considered that the side plate connecting structure of the car as described in Patent Documents 1 and 2 can surely easily perform the side plate connecting operation. However, it can be said that a certain amount of clearance (so-called play amount) is necessary in the connecting structure (between the engaging member and the engaged member) in order to easily perform the side plate connecting operation. This is because, when there is no play amount in the connecting structure part, perfect accuracy is required for the alignment of the engaging member and the engaged member, and the connection workability is significantly impaired (the connection itself is very difficult). This is because it is considered. And it is considered that it is difficult for these connection structures having a certain amount of play to satisfy the connection strength required by the previous standard (for example, no permanent deformation exceeding 1 mm).

  On the other hand, apart from the mechanical strength of the wall surface, it is required that a gap (joint) that causes leakage light does not remain (that is, light shielding property) at the joint portion between the side plates. This is because if there is a gap that causes leakage light at the joint between the side plates, the passenger who notices the leakage light feels uneasy about the mechanical strength and integrity of the wall surface (for example, the wall surface collapses). Because they feel anxiety that they may do it). Factors that leave gaps that cause leakage of light at the joints between the side plates include the manufacturing accuracy of the side plates (particularly, the joint surfaces with adjacent side plates), distortion of the joint surfaces, and the amount of play required for connection work. and so on.

  Therefore, in order to fill a gap in which leakage light is generated, usually, a packing made of an elastic material is sandwiched between adjacent side plates, or a caulking process is performed after the side plates are connected. These sandwiching and caulking treatments reduce the workability of side plate connection (workability of car assembly), but no effective alternative has been found and it has been unavoidable. .

  The present invention has been made in view of the technical background as described above, and its purpose is to perform the side plate connecting operation while ensuring the mechanical strength of the car wall surface and the light shielding property of the joint portion between the side plates. It is an object of the present invention to provide an elevator car having a side plate connecting structure that can be easily performed, and an elevator apparatus using the elevator car.

[First Embodiment]
FIG. 1 is a schematic diagram showing a configuration example of an elevator car according to the present invention, (a) an overall plan view, (b) a perspective view of a main side plate, and (c) a perspective view of a sub side plate. As shown to Fig.1 (a), the elevator car 1 is comprised from the floor board 2, the wall surface 3 stood on the floor board 2, and the ceiling (not shown) arrange | positioned on the wall surface 3 . The wall surface 3 is formed by connecting a plurality of side plates (a front side plate 31, a main side plate 32, and a sub side plate 33) in order to facilitate assembly and installation work in the hoistway.

  The front side plates 31 are side plates disposed on the left and right sides of the entrance / exit of the car (the entrance / exit of the car room), and are usually formed narrower than the other side plates. The main side plate 32 is a side plate used in most of the wall surface 3, and is a side plate that constitutes the feature of the present invention. The sub-side plate 33 is a side plate used for adjusting the arrangement relationship of the main side plate 32.

  The side plates (the front side plate 31, the main side plate 32, and the sub side plate 33) have a first joint surface 35 and a second joint surface 36 that are joined to adjacent side plates at at least one end in the width direction. The first joint surface 35 and the second joint surface 36 are continuous surfaces that are bent so as to be orthogonal to each other, and are positioned outside the car room when the wall surface 3 is formed. In addition, a connection structure portion 37 (engagement hook 38, cutout hole 39) is formed on each joint surface.

  The main side plate 32 has a shape in which one end is bent in a U shape and a shape in which the other end is bent in a step shape when viewed in the cross-sectional shape in the width direction. (See FIGS. 1A and 1B). The sub-side plate 33 has a shape in which both ends are bent in a U-shape when the cross-sectional shape in the width direction is viewed (see FIGS. 1A and 1C). The front side plate 31 shown in FIG. 1 has the same shape as the main side plate 32.

  Further, as shown in FIG. 1A, the two side plates adjacent to each other on the wall surface 3 have a first joint surface 35 and a second joint surface 36 of one side plate, and a first joint surface 35 of the other side plate. And it arrange | positions so that it may cover with respect to the 2nd joint surface 36, and it is connected via the connection structure part 37 (engagement hook 38, notch hole 39) formed in each joint surface. Details of the connection structure portion 37 will be described later.

  By disposing the two adjacent side plates as described above, the mechanical strength at the connecting portion between the side plates can be improved, and the mechanical strength criteria required for the wall surface 3 can be satisfied. In addition, since the joining surfaces of the side plates are composed of two surfaces that are orthogonal to each other, even if there is a slight gap between the joining surfaces (for example, a gap of a play amount necessary for connection work), the leakage substantially occurs. No light is produced. As a result, it is possible to omit packing sandwiching and caulking processes for filling the gaps that were necessary in the past, and the workability of connecting the side plates (workability of car assembly) is improved.

  FIG. 2A is an enlarged perspective schematic view showing an example of a connecting structure of side plates in the present invention. As shown in FIG. 2A, the main side plate 32 has a shape in which one end is bent in a step shape, and has a first bonding surface 35 and a second bonding surface 36 that are bonded to adjacent side plates. Yes. Further, the other end portion of the main side plate 32 has a shape bent in a U-shape, and has a first bonding surface 35 and a second bonding surface 36 that are bonded to adjacent side plates. Each of the first joint surface 35 and the second joint surface 36 is formed with a connecting structure portion 37 (an engagement hook 38 and a notch hole 39 for receiving the engagement hook 38).

  For example, the engaging hook 38 preferably has a protrusion 38a at the center thereof. Thereby, the joining property of the side plates to connect can be improved, and it can contribute to the improvement of the mechanical strength of a wall surface.

  The cutout hole 39 is preferably an isosceles trapezoidal hole. By making the shape of the cutout hole 39 an isosceles trapezoid and making the opening area larger than the projected area of the engagement hook 38, the alignment between the engagement hook 38 and the cutout hole 39 is facilitated. In addition, the length of the bottom of the shorter isosceles trapezoid is preferably the same as the width of the base of the engagement hook 38. As a result, as the engagement between the engagement hook 38 and the cutout hole 39 progresses, the positional relationship between the side plates to be connected is correctly adjusted, and when it is completely engaged, there is no wasteful play and contributes to the improvement of the joint strength. To do.

  As described above, in the car 1 according to the present invention, the engagement hooks 38 and the cutout holes 39 are engaged with each other by abutting the first joining surfaces 35 and the second joining surfaces 36 of adjacent side plates. By connecting the side plates, the wall surface 3 is assembled. That is, the wall surface 3 of the car 1 according to the present invention does not need to be fastened with bolts and nuts for connecting the side plates, and can easily and safely connect the side plates.

  In FIG. 2A, an engagement hook 38 is formed on a joint surface (first joint surface 35 and second joint surface 36) folded in a step shape, and a joint surface (first joint surface) folded in a U-shape. A cutout hole 39 is formed in 35 and the second joining surface 36). However, this invention is not limited to the combination of FIG. 2A, Arbitrary combinations may be sufficient. For example, the notch hole 39 may be formed in the joint surface bent in a step shape, and the engagement hook 38 may be formed in the joint surface bent in a U-shape.

  The engaging hook 38 shown in FIG. 2A is formed by cutting and bending a part of the side plate member itself, but the embodiment of the engaging hook according to the present invention is limited thereto. Instead, for example, the mode shown in FIG. 2B may be used. FIG. 2B is an enlarged perspective schematic view showing another example of the connecting structure portion of the side plates in the present invention. As shown in FIG. 2B, the engagement hook 38 'is formed by molding a member formed separately from the member of the side plate to the side plate by an appropriate method (for example, spot welding, bonding, etc.). is there.

  Further, the engagement hooks 38 and 38 'shown in FIGS. 2A and 2B are engagement hooks that are open at the top and closed at the bottom, and the notch hole 39 has the short bottom at the top and the long bottom at the bottom. However, the aspect of the connecting structure portion of the present invention is not limited thereto, and is a structure in which the upper / lower part is inverted (an engagement hook in which the lower part is opened and the upper part is closed) It may be in the form of an isosceles trapezoidal notch hole in which the shorter bottom is downward and the longer bottom is upward.
