Description

  The present invention relates to an elevator hall sill fixture for adjusting an installation position of a hall sill to a predetermined position at a hall entrance.

  Conventionally, when installing an elevator landing sill at a landing doorway, a ruler is attached to the landing sill, and the position of the landing sill with respect to the piano wire stretched in the hoistway is determined by the ruler. There is known a method of installing an elevator hall threshold that is installed in a vehicle. The ruler is attached to the landing sill by being bolted to a fixing tool inserted into the sill groove of the landing sill (see, for example, Patent Document 1).

JP-A-61-51476

  However, in order to attach the ruler to the landing sill, it is necessary to fasten the ruler to the fixture inserted in the sill groove of the landing sill with bolts, so it takes time to attach the ruler to the landing sill. . In addition, when the fixture is inserted into the sill groove of the landing sill, the position of the fixture relative to the landing sill may be shifted in the length direction of the landing sill. There is a risk of slipping.

  The present invention has been made to solve the above-described problems, and can be easily attached to the landing sill, and moreover, the elevator landing sill can be more accurately attached to the landing sill. The purpose is to obtain a fixture.

  The elevator hall sill installation according to the present invention is an elevator hall sill installation that adjusts the installation position of the hall sill to a predetermined position at the hall entrance based on a piano wire stretched in the hoistway. A fixture body for determining the position of the hall sill with respect to the piano wire in a state attached to the hall sill, the fixture body having a protrusion that fits into a fitting hole provided in the hall sill, and the protrusion is a fitting hole It is attached to the boarding sill by fitting in.

  In the elevator landing sill fixture according to the present invention, the fixture main body is attached to the landing sill by fitting the protrusion of the fixture main body into the fitting hole provided in the landing sill. The fixture body can be attached to the sill. Therefore, the installation tool can be easily attached to the landing threshold.

Embodiment 1 FIG.
FIG. 1 is a longitudinal sectional view showing a hoistway when an elevator according to Embodiment 1 of the present invention is installed in a building. In the figure, on each floor of the building, a landing doorway 3 that connects the inside of the hoistway 1 and the landing 2 is provided. A lifting beam 4 that supports equipment (for example, a hoisting machine) in the hoistway 1 is fixed to an upper end portion in the hoistway 1.

  A landing threshold 5 is installed below each landing entrance 3. When the landing sill 5 is installed at the landing entrance 3, a pair of landing piano wires 6 serving as a reference for the position of the landing sill 5 are stretched vertically in the hoistway 1. The pair of hall piano wires 6 are stretched apart by a predetermined distance in the frontage direction of each hall entrance 3.

  When each hall piano wire 6 is stretched in the hoistway 1, the upper template 7 is arranged in the upper part in the hoistway 1, and the lower template 8 is arranged in the lower part in the hoistway 1. In this example, the upper template 7 is attached to the lifting beam 4 and the lower template 8 is attached to the lower side wall of the hoistway 1. The upper template 7 is a gauge capable of measuring a distance in the horizontal direction. The lower mold plate 8 is provided with a pair of through holes 9 through which the hall piano wires 6 are individually passed.

  The upper end portion of each hall piano wire 6 is connected to the upper template 7. A weight 10 is suspended from the lower end of each hall piano wire 6. Each hall piano wire 6 hangs a weight 10 while being passed through the through hole 9. Thereby, tension is given to each piano wire 6 for halls, and each piano wire 6 for halls is stretched in the vertical direction. The position where each hall piano wire 6 is stretched in the hoistway 1 is determined by an upper template 7 as a gauge.

  The installation position of the landing sill 5 is adjusted to a predetermined position of the landing doorway 3 with reference to each hall piano wire 6 stretched in the hoistway 1. Thereby, the position of the landing sill 5 installed in the landing entrance 3 of each floor is adjusted to a position where the surface on the hoistway 1 side of the landing sill 5 completely overlaps in the vertical direction.

  A car guide rail 11 for guiding a car (not shown) is installed in the hoistway 1. When the car guide rail 11 is installed in the hoistway 1, the car rail piano wire 12 serving as a reference for the position of the car guide rail 11 is stretched in the hoistway 1 in parallel with the hall piano wire 6.

  The upper end portion of the piano wire 12 for the rail is connected to the upper template 7. The lower end portion of the car rail piano wire 12 is connected to a shock absorber base 13 fixed to the bottom portion of the hoistway 1. The position of the car rail piano wire 12 in the hoistway 1 in the horizontal direction is determined with reference to the hall piano wire 6. The position of the car rail piano wire 12 in the horizontal direction with respect to the hall piano wire 6 is determined by the upper template 7 as a gauge.

  The installation position of the car guide rail 11 is adjusted to a predetermined position in the hoistway 1 with the car rail piano wire 12 stretched in the hoistway 1 as a reference. Since the car rail piano wire 12 is stretched with reference to the hall piano wire 6, the installation position of the car guide rail 11 is determined with reference to the hall piano wire 6.

  The position of the car in the horizontal direction is determined based on the position of the car guide rail 11. The position in the horizontal direction of a landing door (not shown) that opens and closes the landing doorway 3 is determined based on the position of the landing threshold 5. Therefore, the positions of the car and the landing door in the horizontal direction are also determined based on the common hall piano wire 6. From this, the positional relationship about the horizontal direction of the hall | door which is arrange | positioned on each floor | floor and the elevator | lifting / lowering in the hoistway 1 becomes fixed.

  Here, when the position in the horizontal direction of the landing sill 5 arranged on a specific floor is greatly shifted, for example, an engagement device for a car door provided on a car and an engagement device for a landing door on a specific floor There is a possibility that problems such as interference when the car moves or interference between the car door engaging device and the landing sill on a specific floor interfere when the car moves. Such a malfunction is prevented by adjusting the position of each landing threshold 5 in the horizontal direction with reference to the common hall piano wire 6.

  FIG. 2 is a perspective view showing a state when the installation position of the landing threshold 5 of FIG. 1 is adjusted to a predetermined position of the landing entrance 3. In the figure, when the installation position of the landing threshold 5 is adjusted to a predetermined position of the landing entrance 3, the fixture 14 is attached to the landing threshold 5. The fixture 14 can be attached to and detached from the landing threshold 5. The installation position of the landing threshold 5 is adjusted to a predetermined position of the landing entrance 3 by adjusting the position of the installation tool 14 with respect to the hall piano wire 6.

  FIG. 3 is a perspective view showing the landing threshold 5 of FIG. FIG. 4 is an enlarged view showing the IV part of FIG. In the figure, the landing threshold 5 is provided with a threshold groove 15 along the length direction of the landing threshold 5. The landing sill 5 is provided with a plurality (two in this example) of fitting holes 16 penetrating in the thickness direction (vertical direction) of the landing sill 5. The fitting holes 16 are arranged at intervals from each other in the length direction of the landing threshold 5.

  As shown in FIG. 4, the sill groove 15 is formed by a pair of groove side surfaces 15a facing each other in the width direction of the landing sill 5, and a groove bottom surface 15b positioned between the lower ends of the groove side surfaces 15a. One opening of each fitting hole 16 is located on the groove bottom surface 15 b of the sill groove 15, and the other opening of each fitting hole 16 is located on the back surface of the landing sill 5. Each fitting hole 16 is a long hole along the length direction of the landing threshold 5. The cross-sectional shape of each fitting hole 16 is a rectangle.

  FIG. 5 is a perspective view showing the fixture 14 of FIG. FIG. 6 is an enlarged view showing a VI portion of FIG. In the figure, the fixture 14 includes a fixture main body 17 that determines the position of the landing threshold 5 with respect to the hall piano wire 6, and a holding member 18 that can be attached to and detached from the fixture main body 17.

  The fixture body 17 includes a plate-like horizontal portion 19, a plate-like handle portion 20 protruding upward from the horizontal portion 19, and a plate-like groove insertion protruding downward from the horizontal portion 19 and inserted into the sill groove 15. Part 21 and a plurality of (two in this example) projections 22 that protrude downward from the groove insertion part 21 and fit into the respective fitting holes 16 individually. In this example, the fixture main body 17 is formed by bending a single plate.

  The fixture main body 17 is attached to the landing sill 5 such that the width direction of the fixture main body 17 coincides with the length direction of the landing sill 5. The dimension in the width direction of the fixture main body 17 is larger than the dimension in the depth direction of the fixture main body 17 (a direction perpendicular to the width direction of the fixture main body 17 and along the horizontal portion 19). The fixture main body 17 is attached to the landing sill 5 when the protrusions 22 are fitted in the fitting holes 16.

  The dimension of the horizontal portion 19 in the width direction of the fixture body 17 is set based on the distance between the pair of hall piano wires 6 stretched in the hoistway 1. That is, the dimension of the horizontal portion 19 in the width direction of the fixture body 17 is slightly shorter than the distance between the pair of hall piano wires 6. Thereby, the horizontal portion 19 can be inserted between the pair of hall piano wires 6 via a predetermined gap.

  The horizontal portion 19 is provided with a pair of notches 23 that are marks for individually matching the landing piano wires 6 when the position of the landing threshold 5 with respect to each landing piano wire 6 is determined. The notches 23 are provided at one end and the other end of the horizontal portion 19 in the width direction of the fixture main body 17. The positions of the notches 23 in the horizontal portion 19 are the same in the depth direction of the fixture body 17. Each notch 23 is formed by two planes that intersect each other.

  The handle portion 20 and the groove insertion portion 21 are arranged along the width direction of the fixture main body 17. Further, the handle portion 20 and the groove insertion portion 21 are arranged at different positions in the depth direction of the fixture main body 17. In this example, with respect to the depth direction of the fixture main body 17, a handle portion 20 is provided at one end portion of the horizontal portion 19, and a groove insertion portion 21 is provided at the other end portion of the horizontal portion 19. In this example, the handle portion 20 and the groove insertion portion 21 are perpendicular to the horizontal portion 19. The height dimension of the groove insertion part 21 from the horizontal part 19 is larger than the depth dimension of the sill groove 15.

  The protrusions 22 are spaced from each other in the width direction of the fixture main body 17. The distance between the protrusions 22 matches the distance between the fitting holes 16. In this example, one protrusion 22 is provided at one end of the groove insertion portion 21, and the other protrusion 22 is provided at the other end of the groove insertion portion 21. The dimension of the protrusion 22 is set to a dimension that fits in the fitting hole 16 without a gap. In this example, each protrusion 22 has a plate shape.

  FIG. 7 is a perspective view showing a state where the fixture main body 17 and the holding member 18 of FIG. 5 are separated. In the figure, the holding member 18 is provided with an insertion groove 24 into which the groove insertion portion 21 is inserted. The shape of the holding member 18 is a rectangular parallelepiped. The holding member 18 is attached to the fixture main body 17 along the groove insertion portion 21 by inserting the groove insertion portion 21 into the insertion groove 24.

  When the fixture main body 17 is attached to the landing sill 5, the holding member 18 is inserted into the sill groove 15 together with the groove insertion portion 21 while being attached to the fixture main body 17. The width dimension of the holding member 18 is set based on the width dimension of the threshold groove 15. As a result, the holding member 18 is fitted into the sill groove 15 without a gap in the width direction of the sill groove 15.

  In this example, the width dimension of the holding member 18 is slightly larger than the distance between the groove side surfaces 15a. In this example, the holding member 18 is made of an elastic material (for example, rubber). Accordingly, the holding member 18 is press-fitted into the sill groove 15 while being elastically deformed by the groove side surface 15 a of the sill groove 15 when the fixture main body 17 is attached to the landing sill 5. Thereby, the wobbling of the fixture 14 with respect to the landing sill 5 is prevented.

  FIG. 8 is a perspective view showing a state in which the fixture 14 of FIG. 5 is attached to the landing threshold 5. FIG. 9 is a perspective view showing a state in which the fixture 14 and the landing threshold 5 in FIG. 8 are separated. FIG. 9 is a perspective view of the landing threshold 5 when viewed from below. As shown in the figure, the fixture 14 is attached to the landing sill 5 with the holding member 18 attached to the fixture main body 17. When the fixture 14 is attached, each protrusion 22 fits in each fitting hole 16 while the holding member 18 is inserted into the sill groove 15.

  In a state where the fixture 14 is attached to the landing threshold 5, the horizontal portion 19 is held at a position protruding from the landing threshold 5 toward the hoistway 1 in the horizontal direction. Therefore, in a state where the fixture 14 is attached to the landing threshold 5, the position of each notch 23 is closer to the hoistway 1 than the position of the landing threshold 5. Further, in a state where the fixture 14 is attached to the landing sill 5, the horizontal portion 19 is disposed in parallel with the upper surface of the landing sill 5.

  FIG. 10 is a top view showing a portion X in FIG. In the figure, when the position of the landing threshold 5 is adjusted to a predetermined position of the landing entrance 3, the respective positions of the notch 23 and the landing piano wire 6 are set with the fixture 14 attached to the landing threshold 5. The notch 23 is aligned with the hall piano wire 6 so as to coincide with the depth direction of the hall entrance 3.

  Next, a procedure for adjusting the hall threshold 5 to a predetermined position of the hall entrance 3 with reference to the hall piano wire 6 stretched in the hoistway 1 will be described. First, a landing threshold 5 is temporarily set up at the landing entrance 3 on each floor. Thereafter, the holding member 18 is attached to the fixture main body 17 to form the fixture 14, and the fixture 14 is attached to the landing sill 5. Attachment of the fixture 14 to the landing sill 5 is performed by fitting each protrusion 22 into each fitting hole 16 while inserting the holding member 18 into the sill groove 15. When the fixture 14 is attached to the landing threshold 5, a part of the fixture main body 17 is arranged between the hall piano wires 6.

  Thereafter, while shifting the fixture 14 together with the temporary landing threshold 5, one notch 23 is aligned with one landing piano wire 6, and the other notch 23 is aligned with the other landing piano wire 6. Thereby, the position of the landing threshold 5 is adjusted to a predetermined position of the landing entrance 3.

  In such an elevator hall sill fixture 14, the fixture body 17 is attached to the hall sill 5 by fitting the protrusion 22 of the fixture body 17 into the fitting hole 16 provided in the hall sill 5. The fixture main body 17 can be attached to the landing sill 5 without using, for example. Therefore, the fixture 14 can be easily attached to the landing threshold 5. Moreover, since the position of the fixture 14 with respect to the landing sill 5 is determined only by inserting the protrusion 22 into the fitting hole 16, the mounting position of the fixture 14 with respect to the landing sill 5 can be set to a more accurate position.

  Further, when the holding member 18 that fits into the sill groove 15 in the width direction of the sill groove 15 is attached to the fixture main body 17, and the fixture main body 17 is attached to the landing sill 5, the holding member 18 is inserted into the sill groove 15. Therefore, the displacement of the holding member 18 in the width direction of the sill groove 15 can be restricted by the groove side surface 15 a of the sill groove 15. Therefore, the wobbling of the fixture main body 17 with respect to the landing sill 5 can be prevented.

  Further, since the fixture body 17 is provided with a notch portion 23 for adjusting the position of the hall threshold 5 with respect to the hall piano wire 6 when the position of the hall threshold 5 is determined, the hall piano wire 6 is notched. It is possible to adjust the position of the landing threshold 5 to a predetermined position of the landing entrance 3 only by combining the portions 23. Therefore, the adjustment of the position of the landing threshold 5 can be further facilitated.

  In addition, a pair of hall piano wires 6 are stretched in the hoistway 1, and a pair of cutout portions 23 that are individually matched to the hall piano wires 6 are provided in the common fixture body 17. The position of the landing sill 5 in each of the entrance direction and the depth direction of the landing entrance 3 can be easily adjusted only by individually aligning the notches 23 with the landing piano wire 6. In addition, the angle of the landing threshold 5 in the horizontal direction with respect to the plane including each hall piano wire 6 can be easily adjusted.

  In the above example, the holding member 18 attached to the fixture main body 17 is inserted into the sill groove 15, but when the projection 22 fits into the fitting hole 16, the fixture main body 17 is put on the landing. The holding member 18 may be omitted as long as it is stably held by the threshold 5.

  In the above example, the fitting hole 16 penetrates the landing threshold 5, but if the protrusion 22 fits into the fitting hole 16, the fitting hole 16 does not penetrate the landing threshold 5. Good.

  In the above example, the opening of the fitting hole 16 is located on the groove bottom surface 15 b, but the opening of the fitting hole 16 may be provided on the upper surface of the landing sill 5. Even if it does in this way, the installation tool main body 17 can be attached to the landing sill 5 only by fitting the protrusion 22 of the installation tool main body 17 in the fitting hole 16, and the installation tool 14 can be easily attached to the landing sill 5. .

  In the above example, the fitting hole 16 is a long hole, but the fitting hole 16 is not limited to a long hole. The cross-sectional shape of the fitting hole 16 may be, for example, a circle or a polygon.

  In the above example, the holding member 18 is made of an elastic material. However, since the holding member 18 only needs to be fitted in the sill groove 15 in the width direction of the sill groove 15, the holding member 18 is, for example, You may be comprised with the metal raw material etc. In this case, the width dimension of the holding member 18 is slightly smaller than the width dimension of the threshold groove 15.
