  FIG. 1 is a front view of an elevator to which a rail bracket device according to the present embodiment is applied. The elevator 1 mainly includes a hoistway 3 extending vertically and a car 5 provided so as to be movable up and down in the hoistway 3. A car guide rail 7 is installed in the hoistway 3 to guide the car 5 so that the car 5 can be raised and lowered. Each of the car guide rails 7 is fixed to a wall (attachment target) 11 that defines the hoistway 3 via rail bracket devices 9 provided at a plurality of locations.

  FIG. 2 is an exploded perspective view of the rail bracket device according to the present embodiment, and FIG. 3 is a plan view of the rail bracket in the rail bracket device. FIG. 4 is an enlarged view of the IV part in FIG. The rail bracket device 9 includes a rail bracket 21 and a plurality of concave washers 23 and convex washers 25.

  As best shown in FIG. 4, the rail bracket 21 is composed of a plate-like member that is substantially S-shaped when viewed from the side. The rail bracket 21 has a first bent portion 27, a second bent portion 29, and a central portion 31. The first bent portion 27 is formed on one end side of the rail bracket 21, the second bent portion 29 is formed on the other end side of the rail bracket 21, and the center portion 31 is the first bent portion. It exists between the part 27 and the 2nd bending part 29, and is located so that they may be connected. The rail bracket 21 is made by bending a single trapezoidal plate so that bent portions 27 and 29 are formed in the unfolded state.

  The first bent portion 27 and the second bent portion 29 are portions that are curved in a side view and an arc shape, respectively. In addition, although the curvature aspect of the 1st bending part 27 and the 2nd bending part 29 shall be the same in this Embodiment, it may differ without being limited to it. Further, the bent outer surface 27a (bent inner side surface 27b) of the first bent portion 27 and the bent outer surface 29a (bent inner side surface 29b) of the second bent portion 29 are the front and back directions of the plate-like rail bracket 21. It is formed on the surface which is the opposite side. In other words, the protruding directions of the first bent portion 27 and the second bent portion 29 are substantially opposite. Further, the central part 31 between the bent parts 27 and 29 is constituted by a substantially flat part.

  As described above, the rail bracket 21 is formed by curving a trapezoidal plate, and the width W1 on the mounting target side of the rail bracket 21, that is, the width of the first bent portion 27 is the width W2 on the rail side, that is, the first width. It is configured to be larger than the width of the second bent portion 29.

  In each of the first bent portion 27 and the second bent portion 29, through long holes 33 and 35 are provided. The first bent portion 27 is provided with two through-holes 33 with a predetermined interval in the left-right direction, and the second bent portion 29 has two intervals with a predetermined interval in the left-right direction. A through long hole 35 is provided. The distance D1 between the pair of through long holes 33 on the attachment target side is set to be larger than the distance D2 between the pair of through long holes 35 on the rail side.

  As described above, the outer shape of the rail bracket 21 made of the trapezoidal plate-like member includes the shape of the first bent portion 27 and the second bent portion 29 and the position and shape of the through long holes 33 and 35 in the left-right direction ( It is formed symmetrically in the left-right direction in FIG. 3 and the front-back direction in FIG.

  Each of the two pairs of through-holes 33 and 35 extends in such a manner that the thickness direction of the penetration changes over the extending direction of the holes. As an example, in the present embodiment, the two pairs of through-holes 33 and 35 extend in a direction parallel to the left-right symmetry line CL of the rail bracket 21 as viewed from the front and back directions of the bracket 21.

  As mainly shown in FIG. 2, the concave washer 23 and the convex washer 25 are respectively combined with the corresponding opposite surfaces of the rail bracket 21 in the front-back direction. The concave washer 23 and the convex washer 25 are prepared in the same number as the through-holes 33 and 35, respectively. Therefore, four in this embodiment are prepared. In FIG. 2, two sets are omitted for the sake of clarity.

  The concave washer 23 and the convex washer 25 are plate-like members each having a bolt through hole at the center. The concave washer 23 has a concave surface 23a combined with the curved outer surface 27a of the first curved portion 27 or the curved outer surface 29a of the second curved portion 29 on one surface, and a flat surface 23b on the other surface. Have. On the other hand, the convex washer 25 has a convex surface 25a combined with the curved inner surface 27b of the first curved portion 27 or the curved inner surface 29b of the second curved portion 29 on one surface, and a flat surface on the other surface. 25b.

  Next, the operation of the rail bracket device according to the present embodiment will be described. As shown mainly in FIG. 4, the rail bracket device 9 has an end on one side approaching the wall 11 defining the hoistway 3 and an end on the other side approaching the car guide rail 7. Arranged. More specifically, the rail bracket device 9 is disposed such that the outer surfaces 27 a and 29 a of the bent portions 27 and 29 face the corresponding wall 11 or the car guide rail 7. The rail bracket 21 is formed by combining a concave washer 23 and a convex washer 25 on the front and back (outside inside) surfaces of the bent portions 27 and 29, and using washers 37, rail clips 39, nuts 41, and the like ( 2), and is connected to the wall 11 and the car guide rail 7 by bolts 43. In this way, the car guide rail 7 is fixed to the wall 11 by the rail bracket device 9.

  Further, the car guide rail 7 can be fixed to the wall 11 using the rail bracket device 9 of the same size even in a mode in which the distance between the wall 11 and the car guide rail 7 is narrower than the state shown in FIG. . FIG. 5 shows a configuration in which the distance L between the wall 11 and the car guide rail 7 is narrower than in the case of FIG. 4, and FIG. As can be understood from FIGS. 5 and 6, the rail bracket device 9 can be operated by changing the inclined posture in which the rail bracket device 9 is arranged, and thereby can be applied over structures having different distances L. That is, the rail bracket 21 of the present embodiment includes bent portions 27 and 29, and through-holes 33 and 35 are formed in the bent portions 27 and 29 so that the thickness direction of the penetration changes over the extending direction of the holes. ing. Therefore, in the mode of FIG. 5, the bolt 43 is penetrated at a position closer to the central portion 31 of the through long holes 33 and 35 than in the case of FIG. 4, and in the mode of FIG. The bolt 43 can be penetrated. In this way, the rail bracket device 9 can cause the rail bracket 21 to function in various inclined postures, and the rail bracket device 9 of one size can be applied over structures having various intervals L. If the mode of FIG. 5 is used as a reference, it can be applied to the mode of FIG. 4 where the interval L is wider than that, and vice versa. For example, if three types of rail brackets 21 of long, intermediate length, and short are prepared in advance, each corresponds to a wide range of intervals, so that it can correspond to almost all wall rail intervals. Is possible.

  In addition, since the strength of the joint of the rail is lower than that of other portions, it may be necessary to arrange the eye plate 45 at the joint as shown in FIG. As the eye plate 45, a reinforced eye plate having a large thickness is usually used. On the other hand, since the rail bracket device 9 has a very wide application range of the wall rail interval L as described above, the additional arrangement at the joint portion is very easy. Therefore, with the additional reinforcement of the rail bracket device 9, it is possible to change the conventional reinforcing eye plate to a normal eye plate with a smaller thickness. In some cases, it is possible to reduce the rail size. Further, even when the rail span is long and the rail strength is lowered, the rail bracket device 9 of the present embodiment can be easily added. In addition, as shown in FIG. 8, if two rail bracket devices 9 are mounted side by side as necessary, the rail strength can be further improved. As described above, the rail bracket device according to the present embodiment can realize an optimum support balance according to the rail installation environment.

  According to the rail bracket device according to the present embodiment described above, the rail bracket device can be used in various arrangement postures, and thus can correspond to various wall rail intervals, such as cutting and welding. Work for adjusting to the interval between the wall rails can be eliminated. Further, it is possible to reduce the time and labor required for using the rail bracket device and shorten the delivery time, and greatly contribute to reducing the burden on the environment by reducing the cutting and welding work. In addition, since the concave washer composed of a concave surface and a flat surface and the convex washer composed of a convex surface and a flat surface are sandwiched and assembled, it is necessary to realize the application to various wall rail intervals as described above. Although the two bent portions are provided, a wide surface contact can be ensured between the wall and the rail and the rail bracket device at the time of fastening, and strong support can be achieved.

  In this embodiment, the rail bracket is formed from a trapezoidal plate so that the bracket width on the mounting target side is wider than the bracket width on the rail side, and the distance between the pair of through slots is also the mounting target. The side can be configured to be wider than the rail side, and the rail bracket can be more firmly fixed to the mounting target. In particular, in the present invention, since it is not directed to the one-way wall rail interval planned as described above, but applied to various wall rail intervals, By widening the interval, even when applied to a structure having a relatively wide wall rail interval, sufficient attachment strength can be easily ensured.

  Also, each through hole extends in a direction parallel to the left-right symmetric line of the rail bracket as viewed from the front and back directions of the bracket, so that the distance between the fastening means is kept constant, and various wall rail intervals are maintained. It is possible to cope with.

  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.

  The bent portion of the rail bracket is not limited to a shape that is curved in an arc shape with a constant radius when viewed from the side. Therefore, for example, it may be curved in an arc shape with a changing radius, or may be gently bent into a polygonal shape that allows the corner to be conceived.

  Further, the through-holes are not limited to two pairs, and may be formed in such a manner that one side each is to be attached and one side of the rail, or conversely, three or more sides are formed on each side. . Furthermore, it is also possible to implement in a mode in which the number of through holes is different between the attachment target side and the rail side.

  The interval between the through holes may be the same on the attachment target side and the rail side. Further, the rail bracket is not limited to being formed from a trapezoidal plate member. For example, the rail bracket is formed from a rectangular plate member, and the width on the mounting target side and the rail side may be the same. .

  The direction in which the through elongated hole extends is not limited to extending in a direction parallel to the left-right symmetry line of the rail bracket as viewed from the front and back directions of the bracket, and is an aspect that extends so that the direction of the through thickness changes. If so, it can be carried out with appropriate modification.

  Moreover, the rail bracket device of the present invention is not limited to supporting the car guide rail, and can be applied to other rails such as a counterweight guide rail.
