JP 2008-37548 A Japanese Utility Model Publication No. 5-75354

  In the conventional elevator apparatus as described above, the rope stopping member is fixed to the upper beam of the car frame, and the upper beam and the pair of vertical columns receive the lifting load of the car. For this reason, it is necessary to manufacture the upper beam and the pair of vertical columns firmly so as to withstand the suspension load of the car. As a result, the car frame is increased in size and weight, and the total weight of the car is relatively large.

  Moreover, in the above conventional elevator type multi-story parking apparatus, since the one end part of several ropes is being fixed to the raising / lowering platform, the member corresponded to a cage | basket | car frame is not used. However, for each of the multiple ropes, it is necessary to satisfy the condition of the angle of entry to the sheave (or curling wheel) of the hoisting machine. Therefore, a plurality of guide pulleys are provided at the upper part of the hoistway, It is necessary to divide a plurality of ropes from the sheave to the plurality of guide pulleys and adjust the hanging position of the plurality of ropes. As described above, since a plurality of ropes are branched at the upper part of the hoistway so as to correspond to the four corners of the hoisting base, the rope winding structure at the upper part of the hoistway is complicated.

  The present invention has been made in order to solve the above-described problems, and an elevator apparatus that can omit a car frame and can simplify a rope wrapping structure in an upper part of a hoistway. The purpose is to obtain.

  The elevator apparatus of the present invention has a plurality of ropes, a main rope hung in the hoistway, a car floor provided in the hoistway, and provided on an outer periphery of the car floor, A plurality of rope stops for fixing one end of the plurality of ropes to the car floor; and a car room provided on an upper surface of the car floor to form a passenger boarding space, near the upper surface of the car room A rope branching mechanism provided to branch the plurality of ropes from a hanging position at the upper part of the hoistway toward each of the plurality of rope stops;

  According to the elevator apparatus of the present invention, the rope branching mechanism branches the plurality of ropes from the suspended position in the upper part of the hoistway toward each of the plurality of rope stops, so that the car frame can be omitted. In addition, since it is not necessary to branch a plurality of ropes with the guide pulley at the upper part of the hoistway, the rope winding structure at the upper part of the hoistway can be simplified.

A plurality of rope-stopping mechanisms (rope shackle mechanisms) 13 </ b> A to 13 </ b> D as the rope-stopping portions are attached to both side portions of the car floor 11 at intervals in the depth direction of the car 10. One ends of the plurality of ropes 1A to 1D are fixed to the rope stopping mechanisms 13A to 13D, respectively. Tightening mechanisms 13 </ b> A to 13 </ b> D receive an eccentric load of the car 10.

  The car room 12 is placed on the upper surface of the car floor 11. A rope guide support member (support frame) 14 having a square shape in plan view is provided on the upper surface (or the vicinity of the upper surface) of the cab 12. That is, the rope guide support member 14 is disposed so as to face the car floor 11 with an interval corresponding to the height corresponding to the height of the passenger boarding space from the upper surface of the car floor 11. A plurality of rope guides 15 </ b> A to 15 </ b> D and a plurality of fixtures (movement prevention stoppers) 16 </ b> A to 16 </ b> D are attached to the rope guide support member 14.

  The rope guides 15A to 15D are arranged so as to overlap with the rope stopping mechanisms 13A to 13D in the vertical direction, respectively. In other words, the rope guides 15 </ b> A to 15 </ b> D are arranged so as to face the tightness position on the car floor 11. The rope guides 15A to 15D have a cylindrical shape, and the ropes 1A to 1D are inserted into the rope guides 15A to 15D. The ropes 1A to 1D are stretched along the vertical direction between the rope guides 15A to 15D and the rope stopping mechanisms 13A to 13D.

  The fixtures 16A to 16D are fixed to the lower surfaces of the rope guides 15A to 15D. Further, the fixtures 16A to 16D are crimped so as to surround the outer peripheral surfaces of the ropes 1A to 1D, respectively. The rope guide support member 14 is fixed to the ropes 1A to 1D by these fixtures 16A to 16D, and the vertical movement of the rope guide support member 14 with respect to the ropes 1A to 1D is restricted.

  A rope stop support member (support frame) 17 having a rectangular shape in plan view is provided at a position away from the rope guide support member 14 by a predetermined height. The rope throttle support member 17 is disposed to face the rope guide support member 14. Moreover, the rope aperture support member 17 is disposed at a location facing the hanging position of the ropes 1A to 1D in the upper part of the hoistway. A plurality of rope stops 18A to 18D and a plurality of fixtures (movement prevention stoppers) 19A to 19D are attached to the rope stop support member 17.

The fixtures 19A to 19D are fixed to the upper surfaces of the rope stops 18A to 18D. The fixtures 19A to 19D are crimped so as to surround the outer peripheral surfaces of the ropes 1A to 1D, respectively. With these fixtures 19A to 19D, the rope throttle support member 17 is fixed to the ropes 1A to 1D, and the vertical movement of the rope throttle support member 17 with respect to the ropes 1A to 1D is restricted.

  Here, the rope guide support member 14, the rope guides 15A to 15D, the rope throttle support member 17 and the rope throttles 18A to 18D constitute a rope branching mechanism. The portions between the rope guides 15A to 15D and the rope stops 18A to 18D in the ropes 1A to 1D are disposed obliquely with respect to the vertical line by the rope branching mechanism. In other words, the ropes 1A to 1D are branched from the hanging position at the upper part of the hoistway toward the rope-holding mechanisms 13A to 13D by the rope distribution mechanism.

  In such an elevator apparatus according to the first embodiment, the ropes 1A to 1D are branched from the hanging position at the upper part of the hoistway toward the rope stopping mechanisms 13A to 13D by the rope branching mechanism. With this configuration, the car frame can be omitted, and the weight of the car can be reduced. At the same time, it is not necessary to branch the ropes 1A to 1D with the guide pulley at the upper part of the hoistway, so that the rope winding structure at the upper part of the hoistway can be simplified.
