Abstract

This guide rail fixing device for an elevator has a first protrusion part and a second protrusion part which protrude from a clip body part in different directions from each other. When a first clip surface of the clip body part is in contact with a rail bracket, a first gap is present between the first protrusion part and the rail bracket; and when a second clip surface of the clip body part is in contact with the rail bracket, a second gap is present between the second protrusion part and the rail bracket. The dimensions of the first and second gaps are different from each other. The state of a rail clip can be switched between a first pressing state in which the first clip surface is brought into contact with the rail bracket to thereby insert a flange part of the guide rail between the first protrusion part and the rail bracket, and a second pressing state in which the second clip surface is brought into contact with the rail bracket to thereby insert the flange part of the guide rail between the second protrusion part and the rail bracket.

The guide rail fixing device 3 can fix both the first guide rail 1a and the second guide rail 1b, which are two types of guide rails 1 having different thicknesses of the flange portion 12, to the rail bracket 2. . In this example, the thickness of the flange portion 12 of the first guide rail 1a is smaller than the thickness of the flange portion 12 of the second guide rail 1b.

The guide rail fixing device 3 includes a rail clip 31 and a fastener 32 that fixes the rail clip 31 to the rail bracket 2.

As shown in FIG. 3, the rail clip 31 includes a clip body 311, and a first protrusion 312 and a second protrusion 313 that protrude from the clip body 311 in different directions. In this example, the rail clip 31 is composed of a single member.

The clip main body 311 is formed with a first clip surface 33 and a second clip surface 34 which are different from each other. The first clip surface 33 and the second clip surface 34 face each other in the thickness direction of the clip main body 311. In this example, the first clip surface 33 and the second clip surface 34 are planes parallel to each other. Moreover, in this example, the shape of the clip main body 311 when viewed along the thickness direction of the clip main body 311 is a square shape.

The first protrusion 312 protrudes from the clip body 311 in a direction orthogonal to the thickness direction of the clip body 311. In this example, the second clip surface 34 is a single plane formed continuously from the clip main body 311 to the first protrusion 312.

The thickness of the first protrusion 312 is smaller than the thickness of the clip main body 311. A first recess 35 formed in accordance with the shape of the flange portion 12 of the first guide rail 1a is provided in a portion of the rail clip 31 on the first clip surface 33 side of the first protrusion 312. Yes.

The second protrusion 313 protrudes from the clip body 311 in a direction orthogonal to the thickness direction of the clip body 311. In this example, the second protrusion 313 protrudes from the clip main body 311 in the direction opposite to the protruding direction of the first protrusion 312. That is, in this example, when the rail clip 31 is viewed along the thickness direction of the clip main body 311, the first protrusion 312 protrudes from one of the two mutually opposing sides of the clip main body 311. A second protrusion 313 protrudes from the other side. In this example, the first clip surface 33 is a single plane formed continuously from the clip body 311 to the second protrusion 313.

The thickness of the second protrusion 313 is smaller than the thickness of the clip main body 311. The positions of the first protrusion 312 and the second protrusion 313 are shifted from each other in the thickness direction of the clip main body 311. Furthermore, the thicknesses of the first protrusion 312 and the second protrusion 313 are different from each other. In this example, the thickness of the first protrusion 312 is larger than the thickness of the second protrusion 313. A second recess 36 formed in accordance with the shape of the flange portion 12 of the second guide rail 1b is provided in a portion of the rail clip 31 on the second clip surface 34 side of the second protrusion 313. Yes.

In a state where the first clip surface 33 is in contact with the mounting surface 21 of the rail bracket 2, as shown in FIG. 1, the first recess 35 causes the first clip surface 33 to be interposed between the rail bracket 2 and the first protrusion 312. 1 gap 37 exists. The dimension H1 of the first gap 37, that is, the dimension between the mounting surface 21 of the rail bracket 2 and the first protrusion 312 is such that the flange 12 of the first guide rail 1a can be inserted. . In a state where the flange portion 12 of the first guide rail 1a is inserted into the first gap 37, the first protrusion 312 contacts the surface of the flange portion 12 of the first guide rail 1a.

In a state where the second clip surface 34 is in contact with the mounting surface 21 of the rail bracket 2, as shown in FIG. 2, the second concave portion 36 causes the second clip surface 34 to be interposed between the rail bracket 2 and the second protrusion 313. There are two gaps 38. The dimension H2 of the second gap 38, that is, the dimension between the mounting surface 21 of the rail bracket 2 and the second protrusion 313 is such that the flange 12 of the second guide rail 1b can be inserted. . In a state where the flange portion 12 of the second guide rail 1b is inserted into the second gap 38, the second protrusion 313 contacts the surface of the flange portion 12 of the second guide rail 1b.

That is, the dimension H1 of the first gap 37 and the dimension H2 of the second gap 38 are different from each other in accordance with the thicknesses of the flange portions 12 of the first guide rail 1a and the second guide rail 1b. ing. In this example, the dimension H 1 of the first gap 37 is smaller than the dimension H 2 of the second gap 38.

As a result, the rail clip 31 is in a state where the first clip surface 33 is brought into contact with the mounting surface 21 of the rail bracket 2 and the flange of the first guide rail 1 a is interposed between the first protrusion 312 and the rail bracket 2. The first pressing state sandwiching the portion 12 and the second clip surface 34 is brought into contact with the mounting surface 21 of the rail bracket 2 so that the second guide rail 1b is interposed between the second protrusion 313 and the rail bracket 2. Switching between the second pressing state with the flange portion 12 in between is possible.

The fastener 32 includes a bolt 321 and a nut 322 fitted to the bolt 321. The clip main body 311 and the rail bracket 2 are respectively provided with bolt through holes 4 that are through holes through which the bolts 321 pass. The bolt through hole 4 provided in the clip main body 311 passes through the clip main body 311 along the thickness direction of the clip main body 311.

The rail clip 31 is provided with a detent portion 5 that prevents the bolt 321 passed through the bolt through hole 4 from rotating relative to the rail clip 31. In this example, a recess formed in accordance with the shape of the head of the bolt 321 is the rotation preventing portion 5. The rotation of the bolt 321 with respect to the rail clip 31 is prevented by fitting the head of the bolt 321 to the rotation stopper 5 which is a recess. The anti-rotation portion 5 is provided on each of the first clip surface 33 and the second clip surface 34. The two detents 5 provided on each of the first clip surface 33 and the second clip surface 34 are connected via the bolt through hole 4.

The rail clip 31 is fixed to the rail bracket 2 by tightening the rail clip 31 and the rail bracket 2 between the head of the bolt 321 and the nut 322.

Next, the procedure for fixing the first guide rail 1a to the rail bracket 2 will be described. When the first guide rail 1 a is fixed to the rail bracket 2, first, the back surface 13 of the first guide rail 1 a is overlapped with the mounting surface 21 of the rail bracket 2.

Thereafter, the rail clip 31 is arranged on the outer side in the width direction of the first guide rail 1a. At this time, the first protrusion 312 is overlapped with the flange portion 12 of the first guide rail 1a, and the first clip surface 33 is brought into contact with the mounting surface 21 of the rail bracket 2. Thereby, the state of the rail clip 31 becomes a first pressing state in which the flange portion 12 of the first guide rail 1a is sandwiched between the rail bracket 2 and the first protrusion 312.

Thereafter, the bolts 321 are passed from the rail clip 31 side to the respective bolt through holes 4 of the rail clip 31 and the rail bracket 2. As a result, the head of the bolt 321 fits in the detent portion 5 provided on the second clip surface 34 of the rail clip 31. Thereafter, the nut 322 is fitted to the bolt 321, and the nut 322 is tightened to the bolt 321. Thereby, the rail clip 31 is fixed to the rail bracket 2 as shown in FIG. Further, the flange portion 12 of the first guide rail 1 a is pressed against the rail bracket 2 by the first protrusion 312 of the rail clip 31 and is frictionally held by the rail bracket 2. In this way, the first guide rail 1a is fixed to the rail bracket 2.

Next, the procedure for fixing the second guide rail 1b to the rail bracket 2 will be described. When the second guide rail 1b is fixed to the rail bracket 2, the back surface 13 of the first guide rail 1a is overlapped on the mounting surface 21 of the rail bracket 2, and then the rail clip is formed on the outer side in the width direction of the first guide rail 1a. 31 is arranged. At this time, if the state of the rail clip 31 is left in the first holding state, the thickness of the flange portion 12 of the second guide rail 1b is between the rail bracket 2 and the first protrusion 312. It does not match the size of the first gap 37. Accordingly, at this time, the state of the rail clip 31 is changed from the first pressing state to the second pressing state in which the front and back of the rail clip 31 are reversed. That is, the second protrusion 313 is overlapped with the flange portion 12 of the second guide rail 1b, and the second clip surface 34 is brought into contact with the mounting surface 21 of the rail bracket 2. Thereby, the state of the rail clip 31 becomes a second pressing state in which the flange portion 12 of the second guide rail 1b is sandwiched between the rail bracket 2 and the second protrusion 313. The subsequent procedure is the same as the procedure for fixing the first guide rail 1a to the rail bracket 2.

In such an elevator guide rail fixing device 3, the first gap 37 exists between the rail bracket 2 and the first projection 312 in a state where the first clip surface 33 is in contact with the rail bracket 2. In the state where the second clip surface 34 is in contact with the rail bracket 2, a second gap 38 exists between the rail bracket 2 and the second protrusion 313, and the dimension H1 of the first gap 37 is Since the dimension H2 of the gap 38 between the two is different from each other, the first guide rail 1a and the second guide rail 1b having different thicknesses of the flange portions 12 can be shared only by reversing the front and back of the rail clip 31. The rail clip 31 can be fixed to the rail bracket 2. That is, the first guide rail 1a can be fixed to the rail bracket 2 and the second guide rail 1b can be fixed to the rail bracket 2 without using a separate type of rail clip. A function for fixing the 1a and the second guide rail 1b to the rail bracket 2 can be given to the common rail clip 31. Thereby, a plurality of types of guide rails 1 having different flange portions 12 can be fixed to the rail bracket 2 with a simple configuration. In addition, since the respective sizes of the first gap 37 and the second gap 38 can be set in accordance with the thicknesses of the flange portions 12 of the first guide rail 1a and the second guide rail 1b, The contact area of the rail clip 31 with respect to each of the flange part 12 and the rail bracket 2 can be increased. Thereby, a plurality of types of guide rails 1 having different thicknesses of the flange portions 12 can be more reliably fixed to the rail bracket 2.

Further, since the rail clip 31 is provided with a detent portion 5 for preventing the bolt 321 passed through the bolt through hole 4 from rotating with respect to the rail clip 31, when the rail clip 31 is fixed to the rail bracket 2. The bolt 321 can be prevented from rotating with respect to the rail clip 31. Thereby, the operation | work which fixes the rail clip 31 to the rail bracket 2 can be made easy. Further, it is possible to prevent loosening of the bolt 321 in a state where the rail clip 31 is fixed to the rail bracket 2 by the fastener 32.

In the above example, the number of protrusions protruding from the clip main body 311 is two of the first protrusion 312 and the second protrusion 313, but the first protrusion 312 and the second protrusion 313 are two. Three or more protrusions may protrude from the clip body 311 by projecting another protrusion in addition to the protrusion 313 from the clip body 311. For example, of the four sides of the quadrilateral of the clip main body 311 when viewed along the thickness direction of the clip main body 311, the side from which the first protrusion 312 and the second protrusion 313 protrude Another protrusion may protrude from a different side. In this case, another protrusion protrudes from the clip main body 311 in a direction different from that of the first protrusion 312 and the second protrusion 313. Further, in this case, the first clip surface 33 or the second clip surface 34 is in contact with the mounting surface 21 of the rail bracket 2 and is present between another protrusion and the mounting surface 21 of the rail bracket 2. The dimension of the gap to be made is different from each of the dimension H1 of the first gap 37 and the dimension H2 of the second gap 38. In this way, the common rail clip 31 can be provided with a function for fixing the three or more types of guide rails 1 having different thicknesses of the flange portions 12 to the rail bracket 2.

A first recess 35 formed in accordance with the shape of the flange portion 12 of the first guide rail 1a is provided in the portion of the rail clip 31 on the clip surface 39 side of the first protrusion 312.

The second protrusion 313 protrudes from the clip body 311 in a direction orthogonal to the thickness direction of the clip body 311. In this example, the second protrusion 313 protrudes from the clip main body 311 in the direction opposite to the protruding direction of the first protrusion 312. That is, in this example, when the rail clip 31 is viewed along the thickness direction of the clip main body 311, the first protrusion 312 protrudes from one of the two mutually opposing sides of the clip main body 311. A second protrusion 313 protrudes from the other side.

The thickness of the second protrusion 313 is smaller than the thickness of the clip main body 311. In addition, the thicknesses of the first protrusion 312 and the second protrusion 313 are different from each other. In this example, the thickness of the first protrusion 312 is larger than the thickness of the second protrusion 313. A second recess 36 formed in accordance with the shape of the flange portion 12 of the second guide rail 1b is provided in a portion of the rail clip 31 on the clip surface 39 side of the second protrusion 313.

In a state where the clip surface 39 is in contact with the mounting surface 21 of the rail bracket 2, as shown in FIGS. 4 and 5, the first recess 35 causes the first protrusion 312 to move between the rail bracket 2 and the first protrusion 312. 1 gap 37 exists, and the second recess 38 exists between the rail bracket 2 and the second protrusion 313 by the second recess 36.

The dimension H1 of the first gap 37, that is, the dimension between the mounting surface 21 of the rail bracket 2 and the first protrusion 312 is such that the flange 12 of the first guide rail 1a can be inserted. . In a state where the flange portion 12 of the first guide rail 1a is inserted into the first gap 37, the first protrusion 312 contacts the surface of the flange portion 12 of the first guide rail 1a.

The dimension H2 of the second gap 38, that is, the dimension between the mounting surface 21 of the rail bracket 2 and the second protrusion 313 is such that the flange 12 of the second guide rail 1b can be inserted. . In a state where the flange portion 12 of the second guide rail 1b is inserted into the second gap 38, the second protrusion 313 contacts the surface of the flange portion 12 of the second guide rail 1b.

Thereby, the state of the rail clip 31 is such that the clip surface 39 is brought into contact with the mounting surface 21 of the rail bracket 2, and the flange portion 12 of the first guide rail 1 a is placed between the first protrusion 312 and the rail bracket 2. The first holding state to be sandwiched, and the clip surface 39 is brought into contact with the mounting surface 21 of the rail bracket 2 to sandwich the flange portion 12 of the second guide rail 1b between the second protrusion 313 and the rail bracket 2. Switching between two holding states is possible.

The clip body 311 is formed with another clip surface 40 that faces the clip surface 39 in the thickness direction of the clip body 311. Another clip surface 40 is a flat surface formed continuously from the clip main body 311 to each of the first protrusion 312 and the second protrusion 313. The rotation stopper 5 is provided only on another clip surface 40 of the clip main body 311. Accordingly, the detent portion 5 is provided only at one end portion of the bolt through hole 4 penetrating the clip main body portion 311. Other configurations are the same as those in the first embodiment.

Next, the procedure for fixing the first guide rail 1a to the rail bracket 2 will be described. When fixing the first guide rail 1a to the rail bracket 2, the back surface 13 of the first guide rail 1a is overlaid on the mounting surface 21 of the rail bracket 2 in the same manner as in the first embodiment, and then the first guide rail 1a is fixed. A rail clip 31 is arranged on the outer side in the width direction of the rail 1a.

At this time, the first protrusion 312 is overlapped with the flange portion 12 of the first guide rail 1a, and the clip surface 39 is brought into contact with the mounting surface 21 of the rail bracket 2. Thereby, the state of the rail clip 31 becomes a first pressing state in which the flange portion 12 of the first guide rail 1a is sandwiched between the rail bracket 2 and the first protrusion 312. The subsequent procedure is the same as the procedure for fixing the first guide rail 1a to the rail bracket 2 in the first embodiment.

Next, the procedure for fixing the second guide rail 1b to the rail bracket 2 will be described. When the second guide rail 1b is fixed to the rail bracket 2, the back surface 13 of the first guide rail 1a is overlapped on the mounting surface 21 of the rail bracket 2, and then the rail clip is formed on the outer side in the width direction of the first guide rail 1a. 31 is arranged.

At this time, if the state of the rail clip 31 is left in the first holding state, the thickness of the flange portion 12 of the second guide rail 1b is between the rail bracket 2 and the first protrusion 312. It does not match the size of the first gap 37. Therefore, at this time, the state of the rail clip 31 is changed to the second pressing state in which the front and rear of the rail clip 31 are reversed from the first pressing state. That is, the second protrusion 313 is overlapped with the flange portion 12 of the second guide rail 1 b and the clip surface 39 is brought into contact with the mounting surface 21 of the rail bracket 2. Thereby, the state of the rail clip 31 becomes a second pressing state in which the flange portion 12 of the second guide rail 1b is sandwiched between the rail bracket 2 and the second protrusion 313. The subsequent procedure is the same as the procedure for fixing the first guide rail 1a to the rail bracket 2.

In such an elevator guide rail fixing device 3, the first gap 37 exists between the rail bracket 2 and the first protrusion 312 with the clip surface 39 in contact with the rail bracket 2, and the rail Since the second gap 38 exists between the bracket 2 and the second protrusion 313 and the dimension H1 of the first gap 37 and the dimension H2 of the second gap 38 are different from each other, the rail clip The first guide rail 1 a and the second guide rail 1 b with different thicknesses of the flange portion 12 can be fixed to the rail bracket 2 by the common rail clip 31 only by reversing the front and rear of 31. That is, the first guide rail 1a can be fixed to the rail bracket 2 and the second guide rail 1b can be fixed to the rail bracket 2 without using a separate type of rail clip. A function for fixing the 1a and the second guide rail 1b to the rail bracket 2 can be given to the common rail clip 31. Thereby, a plurality of types of guide rails 1 having different flange portions 12 can be fixed to the rail bracket 2 with a simple configuration. In addition, since the respective sizes of the first gap 37 and the second gap 38 can be set in accordance with the thicknesses of the flange portions 12 of the first guide rail 1a and the second guide rail 1b, The contact area of the rail clip 31 with respect to each of the flange part 12 and the rail bracket 2 can be increased. Thereby, a plurality of types of guide rails 1 having different thicknesses of the flange portions 12 can be more reliably fixed to the rail bracket 2.

In the above example, the number of protrusions protruding from the clip main body 311 is two of the first protrusion 312 and the second protrusion 313, but the first protrusion 312 and the second protrusion 313 are two. Three or more protrusions may protrude from the clip body 311 by projecting another protrusion in addition to the protrusion 313 from the clip body 311. For example, of the four sides of the quadrilateral of the clip main body 311 when viewed along the thickness direction of the clip main body 311, the side from which the first protrusion 312 and the second protrusion 313 protrude Another protrusion may protrude from a different side. In this case, another protrusion protrudes from the clip main body 311 in a direction different from that of the first protrusion 312 and the second protrusion 313. Further, in this case, the size of the gap existing between another protrusion and the mounting surface 21 of the rail bracket 2 in a state where the clip surface 39 is in contact with the mounting surface 21 of the rail bracket 2 is the first clearance. The dimension H1 is different from the dimension H1 of 37 and the dimension H2 of the second gap 38. If it does in this way, the common rail clip 31 which can fix the 3 or more types of guide rail 1 from which the thickness of the flange part 12 differs to the rail bracket 2 can be manufactured.
