  • the rail joint member 73 may be directly fixed to the tops of the guide rails 5a and 5b in place of the members 721a and 721b.
  • the rail attachment unit 72 which includes the contact portions 722a and 722b overlapping, on a projection view from the top, the upper ends of the guide rails 5a and 5b, is fixed so that the contact portions 722a and 722b come in contact with the upper ends of the guide rails 5a and 5b. Accordingly, even if their joint between the rail attachment unit 72 and the guide rails 5a and 5b is loosened, the force F acting on the hoisting machine 6 is received by the contact portions 722a and 722b; therefore, the high-reliable elevator system can be obtained by the simple configuration.
  • the rail attachment unit 72 is fixed in a state that the contact portions 722a and 722b do not contact to the upper ends of the guide rails 5a and 5b, and the joint between the rail attachment unit 72 and the guide rails 5a and 5b may occasionally slide to move the rail attachment unit 72 downward, the contact portions 722a and 722b are trapped to the upper ends of the guide rails 5a and 5b, so as to support the force F acting on the hoisting machine 6; therefore, the high-reliable elevator system can be obtained.
  • the rail attachment unit 72 is attached to the guide rails 5a and 5b by providing fixation holes in the guide rails followed by bolt jointing using bolts passing through the fixation holes, even if slide occurs on this joint structure, the force F acting on the hoisting machine 6 is received by such an engaging structure of the bolts with the fixation holes.
  • the fixation holes are needed to be processed in the guide rails 5a and 5b, the cross section properties in the fixation-hole portions of the guide rails 5a and 5b are deteriorated, and the strength of the guide rails 5a and 5b is resultantly deteriorated.
  • the fixation holes are not needed to be processed in the guide rails 5a and 5b; therefore, the strength is not also deteriorated.
  • suspension-means anchor section 12 for anchoring the suspension means 10 is provided on the hoisting-machine mounting unit 71, the other elements for attaching the suspension means are not needed; therefore, the number of elements can be reduced.
  • the hoisting machine 6 can be placed without increasing in the vertical direction of the hoistway 1.
  • the hoisting-machine mounting unit 71 is placed, viewed from the horizontal direction, within the range in the longitudinal direction of the guide rails 5a and 5b; however, the hoisting-machine mounting unit 71 may be placed in such a way that a portion thereof comes out of the range in the longitudinal direction of the guide rails 5a and 5b.
  • Fig. 12 , Fig. 13 , Fig. 14 , Fig. 15 , and Fig. 16 illustrate a hoisting-machine mounting mechanism of an elevator system according to embodiment 2 of the present invention, in which Fig. 12 is a front view, Fig. 13 is a cross-sectional view of a cross section E - E in Fig. 12 , Fig. 14 is a front view of an enlarged view illustrating the main upper portion of the hoisting-machine mounting mechanism, Fig. 15 is a side view, and Fig. 16 is a view illustrating a cross section G - G.
  • Embodiment 2 provides partial contact parts 74, limiters 75, and adjusters 76, at the upper portions of the rail attachment unit 72. Because the other configurations are similar to those in Embodiment 1, their explanation is omitted. Here, the same numerals as those in Embodiment 1 represent corresponding elements.
  • the partial contact part 74, the limiter 75, and the adjuster 76 placed on the side of the guide rail 5a are explained using Fig. 14 , Fig. 15 and Fig. 16 .
  • the partial contact part 74 is provided between the contact portion 722a of the rail attachment unit 72 and the upper end of the guide rail 5a.
  • the partial contact part 74 is placed, on a projection view from the top, so as to partially overlap with a portion of the center on the upper end of the guide rail 5a.
  • the partial contact part 74 is fixed to the contact portion 722a.
  • the limiter 75 is configured with a rod shaped limiter such as a pair of bolts 75a and 75b, which is provided at the upper portion of the rail attachment unit 72.
  • the bottom faces of the bolts 75a and 75b are positioned under the upper end of the guide rail 5a, and are placed on both sides of the guide 52a of the guide rail 5a. Thereby, the limiter 75 limits the movement of the rail attachment unit 72 in a horizontal direction thereof.
  • the bolts 75a and 75b are jointed together with the rail joint member 73 to the contact portion 722a.
  • the adjuster 76 which is formed in plate-like shape, is placed between the contact portion 722a and the upper end of the guide rail 5a.
  • the adjuster 76 is placed between the partial contact part 74 and the upper end of the guide rail 5a. Due to construction misalignment of the guide rail 5a, a margin of error may occur in the gap between the contact portion 722a and the upper end of the guide rail 5a. In this case, by placing the number of the adjusters 76 corresponding to the error of the gap, the gap between the contact portion 722a and the upper end of the guide rail 5a is adjusted. Holes are formed in the adjuster 76, through which the bolts 75a and 75b pass.
  • the configuration is similar to those of the side of the guide rail 5a.
  • the partial contact parts 74 each provided between the respective contact portions 722a and 722b at the upper portion of the rail attachment unit 72 and the respective upper edges of the guide rails 5a and 5b are placed, on the projection view from the top, so as to overlap with respective portions of the centers of the upper edges of the guide rails 5a and 5b.
  • the limiters 75 provided at the upper portions of the rail attachment unit 72 limit the movement, in a horizontal direction, of the rail attachment unit 72, the bolts 75a and 75b as the limiters 75 are placed at respective both sides of the rail guide portions 52a and 52b. Thereby, even if any of the clips 54 that links the rail attachment unit 72 with the guide rails 5a and 5b goes away, and thus the members 721a and 721b tend to move in a direction perpendicular to the gap direction between the guide rails 5a and 5b, because the bolts 75a or 75b comes in contact with the side face of the rail guide portion 52a or 52b, the movement of the members 721a and 721 b are restricted.
  • the rail attachment unit 72 can surely receive the force F acting on the hoisting machine 6 without the contact portions 722a and 722b departing in a direction perpendicular to the gap direction between the guide rails 5a and 5b; thus, the elevator system can be obtained with a higher reliability.
  • the adjusters 76 are placed between the upper ends of the guide rails 5a and 5b and the contact portions 722a and 722b, respectively, by adjusting the gaps between the upper edges of the guide rails 5a and 5b and the contact portions 722a and 722b, respectively, even though the construction errors of the guide rails 5a and 5b are implied, the rail attachment unit 72 can be accurately fixed in the vertical direction, and because the contact portions 722a and 722b are supported by the guide rails 5a and 5b, the force F acting on the hoisting machine 6 can be surely received.
  • the adjusters 76 have been placed between the partial contact parts 74 and the upper ends of the guide rails 5a and 5b, the invention is not limited to that configuration.
  • the partial contact parts 74 may contact to the upper ends of the guide rails 5a and 5b, and the adjusters 76 may be placed between the contact portions 721a and 721b and the partial contact parts 74.
  • the adjusters 76 may be placed, in a state without the partial contact parts 74, between the contact portions 722a and 722b and the upper ends of the guide rails 5a and 5b.
  • the holes are formed in the adjusters 76, through which the bolts 75a and 75b as the rod-shaped limiters pass.
  • the bolts 75a and 75b as the limiters 75 have been provided at both sides of the guides 52a and 52b; however, the invention is not limited to that configuration.
  • the bolts 75a and 75b may be configured to be provided at both sides of the rail bottom portions 51a and 51b. In this case, because the bolts 75a and 75b also come in contact with the side faces of the rail bottom portions 51a and 51b, and thus limit the movement of the rail attachment unit 72, the contact portions 722a and 722b never depart in a direction perpendicular to the gap direction between the guide rails 5a and 5b.
  • limiters may also be provided on the head sides of the rail guide portions 52a and 52b.
  • the limiters provided at both sides of the rail guide portions 52a and 52b limit movement both in the perpendicular direction and in the gap direction berween the guide rails 5a and 5b of the rail attachment unit 72.
  • the limiters provided on the head sides of the rail guide portions 52a and 52b limit movement in the gap direction berween the guide rails 5a and 5b of the rail attachment unit 72. Therefore, the rail attachment unit 72 can further surely support the force F acting on the hoisting machine 6 without the contact portions 722a and 722b departing both in the perpendicular direction and in the gap direction berween the guide rails 5a and 5b.
