BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a three-sided frame for an elevator entrance.

0003

2. Description of the Related Art A conventional three-sided frame of an elevator entrance will be explained with reference to FIGS. 5 and 6.

[0004] The entrance/exit frame forming the entrance/exit of the elevator hall is constructed by connecting two-way frames 1 erected on the left and right sides and a curtain plate 2 extending horizontally across the front upper part.

The structure of this two-sided frame 1 is composed of inclined side surfaces having an angle that becomes narrower from the landing side toward the car.

On the other hand, the curtain board is inclined so that its left and right ends match the inclined side surfaces of the two-way frame 1, and the two-way frame 1 is formed on the left and right sides.
They are arranged in such a way that they are in contact with each other and sandwiched between them.

That is, the two-sided frame 1 is configured to pass through to the upper end of the curtain plate 2, while avoiding the header case 4 at the upper part of the back side, and sandwich the curtain plate 2 along the slope of the two-sided frame 1. A three-sided frame is constructed by fastening bolts and nuts 7 to mounting holes of an L-shaped reinforcement 5 and an L-shaped reinforcement 6 provided in the two-sided frame 1 and the curtain plate 2, respectively.

Since the inclined side portion of the two-sided frame 1 has a bent plate structure, a reinforcement 8 is attached to the back surface by welding.

[0009]

[Problem to be Solved by the Invention] In this way, since the entire vertical width of the curtain plate is sandwiched and connected to the two-sided frame, in the case of a three-sided frame with sloped sides of the two-sided frame, Even if there is a slight difference between the inclination angle of the two-sided frame and the inclination angle of the curtain plate,
A gap occurs in the mating part.

[0010] Furthermore, since the inclined side surface portion of the two-way frame has a plate bending structure, the middle part of the two-way frame may bulge due to bending work or tensile strain caused by welding reinforcement attached to the back side of the two-way frame. As assembly with the board is done by matching the actual parts, it takes a lot of time to assemble the curtain board by filing and adjusting it to match the bulge in the two-sided frame.

As mentioned above, it is difficult to deal with even slight dimensional errors and assembly work is difficult. Therefore, the three-sided frame shipping format must be assembled as one unit, shipped, and delivered to the site, which increases transportation costs such as packaging, etc. More and more space is needed.

[0012] The present invention simplifies the structure of the two-sided frame and the curtain plate, eliminates the need to match the actual parts during assembly, and has a structure that can prevent gaps and distortions in the mating parts regardless of the inclination dimension of the two-sided frame. The purpose is to make it possible to ship and carry in a divided form, and to simplify the transportation method.

[Configuration of the invention]

[0014]

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a method for connecting a two-sided frame and a curtain plate, in which the front part of the curtain plate is provided so as to be in contact with the two-sided frame, and the back side is provided so as to be in contact with the two-sided frame. Insert it into the notch provided in the square frame, and fasten and secure the area near it using a fastening material.

[0015]

[Operation] When assembling the three-sided frame, the inclined side portions of the two-sided frame and both end faces of the curtain plate (thickness cross section) are butted together, and the back side of the curtain plate is inserted into the notch of the two-sided frame for L-shaped reinforcement. concluded through.

[0016] Since the insertion shape is adopted as described above, the appearance is the same as the conventional one, and there is no difference in design. Furthermore, since the abutting portion is small, errors in dimensional alignment of the inclined side surface portion are less likely to occur.

[0017]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be explained based on the embodiments shown in FIGS. 1 to 3.
