Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a guiding device for an elevator that facilitates bonding portion of the guide rail comprising by joining a plurality of rail members.
[0002]
[Prior art]
Conventionally, as a guide rail erected on both sides of the car of the elevators, there is those Hence coupled to bolts through the seam plate a plurality of rail members formed by molding of one steel plate.
[0003]
The blade portion of the rail member, low la Contact and shoe over the Roragai de attached to the car is in contact. Basket is moved up and down along the guide rails, but low La at this time Roragai de will roll on the blade unit.
[0004]
[Problems to be solved by the invention]
By the way, such a rail material may be slightly misaligned due to a slight bending of the blade portion during molding or conveyance. When joining the rail material core of the blade is shifted, so that the step difference occurs at the junction portion of the rail member. Then, when the row La that roll over the blade portion passes over the step, it becomes possible to generate vibration or noise, etc., there is a problem that uncomfortable feeling to passengers riding in the car It was.
[0005]
An object of the present invention is to provide an elevator guide device in which a step is not generated at a joint portion of a plurality of rail members.
[0006]
[Means for Solving the Problems]
To achieve the above object, according to the present invention, a rail member overlapping the shaped inner rail member of a substantially U inside the outer rail material shaped cross section substantially U ing vertically A guide device for an elevator in which a guide rail is configured by joining a plurality of rollers, and three rollers facing the three directions of the roller guide respectively roll on three inner surfaces of the inner rail member of the guide rail. The first protrusion of the first inner rail member that is the inner rail member of the one rail member from the end of the first outer rail member that is the outer rail member of one of the pair of upper and lower rail members. with part projects, has a second projecting portion of the second outer rail member from the end portion of the second inner rail member is an inner rail member of the other rail member is the outer rail member of the other rail member is projected The first bump Portion is superimposed on the inner side of the second projecting portion, the both projecting portions are connected by a bolt and nut which passes through the connecting holes formed respectively in the both widthwise end portions of the bottom wall of these two projecting portions At the same time, the roller in contact with the bottom wall of the inner rail member of the roller guide is configured to roll at the center in the width direction of the bottom wall .

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described with reference to the drawings. 1 to 4 are views showing an embodiment of an elevator guide apparatus according to the present invention.
[0008]
In FIG. 3, reference numeral 1 denotes a car disposed on the hoistway so as to be movable up and down. The car 1 includes a car room 2 and a car frame 3 that supports the car room 2. Roller guides 4 and 5 are provided at both upper and lower ends of the car frame 3, and the roller guides 4 and 5 run on guide rails 6 erected on the side of the car 1.
[0009]
As shown in FIG. 4, the guide rail 6 has a substantially U-shaped cross section. The inner side of the guide rail 6 faces the car side, and the inner side has three inner surfaces. Rollers 5a, 5b, 5c facing the three directions of the roller guide 5 are in contact with the three inner surfaces of the guide rail 1, and roll on this.
[0010]
As shown in FIG. 1, the guide rail 6 is formed by joining a plurality of rail members 7, 8. The rail member 7 is superimposed on the first outer rail member 9 having a substantially U-shaped cross section, and is overlapped thereon. The first inner rail member 10 has a substantially U-shaped cross section. Both side ends of the first inner rail member 10 are bent, and both end portions of the first outer rail member 9 are inserted into the bent portion. The first outer rail member 9 and the first inner rail member 10 are formed with connecting holes 9a and 10a, and are connected and fixed by bolts and nuts passing through the connecting holes 9a and 10a. Further, the first inner rail member 10 protrudes downward in FIG. 1 from the end portion 9 b of the first outer rail member 9. Similarly to the above, the rail material 8 has a configuration of the second outer rail material 11 and the second inner rail material 12, and the second outer rail material 11 (having connection holes 11a and 12a) is the second inner rail material. 1 protrudes upward in FIG. 1 from the end 12b of the material 12.
[0011]
The first projecting portion 10b of the first inner rail member 10 and the second projecting portion 11b of the second outer rail member 11 are overlapped and connected and fixed by bolts and nuts. As shown in FIG. 2, the end portion 10 c of the first inner rail member 10 and the end portion 12 b of the second inner rail member 12 are abutted, and the end portions 10 c and 12 b are in contact with the second outer rail member 11. It is supported from the side and pressed by bolts and nuts. For this reason, the end portion 10c of the first inner rail member 10 and the end portion 12b of the second inner rail member 12 are not stepped and are held on the same plane.
[0012]
Therefore, when the rollers 5a, 5b, 5c facing the three directions of the roller guide 5 run on the three inner surfaces of the first and second inner rail members 10, 12, there is no step between the end portions 10c, 12b. It will run smoothly.
[0013]
【The invention's effect】
As described above, according to the present invention, the first protrusion of the first inner rail member protruding from the first outer rail member is the second protrusion of the second outer rail member protruding from the second inner rail member. Since the first projecting part and the second projecting part are connected to each other by a connector, the roller guide roller travels on the three inner surfaces of the first and second inner rail members. Can run smoothly.
