Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator guide rail capable of connecting a plurality of rail members without a joint plate.

[0002]

2. Description of the Related Art As a conventional guide rail of an elevator, for example, there is one as shown in FIG. In the figure, reference numeral 101 denotes a guide rail provided on both sides for guiding the car, and the guide rail 101 is formed by joining a plurality of rail members 102 and 103.
The rail members 102 and 103 are formed by shaping a single steel plate by machining. The rail members 102 and 103 are brought into contact with each other, and then joined by bolts 105 via a joint plate 104.

[0003]

However, in the conventional guide rail of an elevator, a plurality of rail members 102 and 103 are connected via a seam plate 104. There is a problem that the seam plate 104 is required and the number of parts increases.

[0004] It is an object of the present invention to enable a plurality of rail members to be connected without a joint plate.

[0005]

In order to achieve the above object, according to the present invention, there is provided a guide rail for an elevator comprising a plurality of rail members. The line and the horizontal center line are divided into a diagonally upper right, diagonally lower right, diagonally upper left and diagonally lower left, and the diagonally upper left and diagonally lower left of one end thereof are cut out, and the remaining diagonally lower right and diagonally upper left are cut off. Cut off the diagonally upper right and diagonally lower left parts of the other end, and separate the remaining diagonally lower right part and diagonally upper left part, so that the other end of one rail member and one end of the other rail member are mutually separated. It is configured to be fitted to.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. 1 to 5 are views showing an embodiment of an elevator guide rail according to the present invention.

In FIG. 1, reference numeral 1 denotes a guide rail that stands on both sides of a car in a hoistway, and the guide rail 1 is composed of a plurality of rail members 2 and 3. The rail member 2 is composed of a substrate portion 2a and a blade portion 2b perpendicular to the substrate portion 2a, and a roller of a roller guide provided on a car slides on the blade portion 2b.

As shown in FIGS. 2 and 3, the rail member 2 has an elongated rail shape, and upper and lower ends 4, 5 of the rail member 2 can be connected to other rail members.

The upper end 4 of the rail member 2 is formed by a vertical center line CL1 and a horizontal center line CL2 as shown in FIG.
It is divided into. The diagonally upper left portion 8 and the diagonally lower right portion 7 of the upper end portion 4 are cut and cut out. Also,
The remaining diagonally upper right part 6 and diagonally lower left part 9 are separated. An insertion hole 10 for inserting a bolt is provided in each of the upper right portion 6 of the upper right portion 4 and the lower right portion 9 (the substrate portion 2a).
11 are formed.

[0010] Similarly, as shown in FIG.
The upper right diagonal part 12, the right diagonal lower part 13, the left diagonal upper part 14, and the left diagonal lower part 15 are also partitioned, and the right diagonal upper part 12 and the left diagonal lower part 15 are notched. Also, the lower right 13
And the upper left oblique portion 14 (substrate portion 2a) are separated from each other, and insertion holes 16 and 17 are formed respectively.

When the other end 5 of the one rail member 2 and the one end 4 of the other rail member 3 are combined, the left oblique upper part 12 and the right oblique lower part 15 of the other end 5 of the rail member 2 are cut out. , The upper right diagonal part 6 and the lower left diagonal part 9 of the one end 4 of the rail member 3 just fit.
At this time, the insertion hole 16 of the lower right oblique portion 13 at the other end 5 of the rail member 2 communicates with the insertion hole 10 of the lower right oblique portion 6 at the one end 4 of the rail member 3. Insertion hole 17 in diagonally left upper part 14 at end 5 and insertion hole 1 in diagonally lower left 9 at one end 4 of rail member 3
Communicates with 1. Therefore, a bolt is inserted into the communication holes 10 and 16 and a bolt is inserted into the communication holes 17 and 11 to connect the one rail member 2 and the other rail member 3 without a joint plate.

Since the rail members 2 and 3 have one end and the other end symmetrical, there is no directivity, and when they are fitted to each other, one end and the other end of the rail member 2 are not provided. The part can be fitted at either one end or the other end of the rail member 3, which improves workability.

[0013]

As described above, according to the present invention,
Since the other end of one rail member and the one end of the other rail member are fitted to each other, a plurality of rail members can be connected without a joint plate, and the number of parts can be reduced. it can.
