Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an entrance/exit device in which members are assembled into a mouth shape and installed in an elevator landing, and in particular to the structure of the joints of each member.

[Prior art] First, by referring to Figures 1 and 2, for example,
A conventional elevator hall entrance/exit system similar to that shown in Japanese Patent No. 15955 will be described.

In the figure, 1 is the elevator hoistway, 2 is the hoistway 1
3 is an entrance provided on the floor 2 and communicates with the hoistway 1; 4 is a sill whose longitudinal length is horizontal and forms the lower edge in the frontage direction of the entrance 3; 5, 5 ' are side members that are arranged vertically apart from each other and constitute the side edges of the entrance/exit 3, and are made of bent steel plates, and angle-shaped steel-shaped mounting bodies 5a are spotted on the upper and lower edges of the back side. It is fixed by welding 5b. Numeral 6 is a fastener made of bolts and nuts for fastening the mounting body 5a at the lower edge of the side members 5, 5' to the sill 4, and 7 is an upper panel formed by bending a steel plate to form a groove in cross section, one side of the groove. The side walls of the side members 5, 5' are arranged in an overlapping state on the upper surface of the mounting body 5a at the upper edges of the side members 5, 5', and are provided horizontally to form the entrance/exit 3.
An upper edge member 8 constitutes the upper edge of the side member 5, 5'
A fastener consisting of a bolt and a nut fastens the upper edge mounting body 5a and the upper edge material 7, 9 is a hanger case fixed in the groove of the upper edge material 7, 10 is the upper end attached to the hanger case 9, and the lower end It is a sliding door that is guided by a threshold 4 and operates to open and close an entrance/exit 3.

That is, the sill 4, the side members 5, 5', the upper edge member 7
is assembled into a mouth shape, and a hanger case 9 is attached to this.
The entrance/exit device is configured such that the sliding door 10 is fixed and the sliding door 10 is installed on the floor 2.

[Problem that the invention aims to solve] Since the entrance and exit devices for elevator landings are manufactured in a factory and then transported and installed at the location where the elevator is installed, it is important to make them strong so that they do not deform during transportation. be.

In order to prevent the doorway frame from deforming during transportation or installation, it is necessary to firmly fix the side members 5, 5', the upper edge material 7, and the sill 4 in a four-sided frame shape. Fixing means 5b near and below tool 8
It is important to have a highly rigid structure around the area.

The device disclosed in Japanese Utility Model Publication No. 54-15955 had the disadvantage that there was no reinforcing material in the bolted part for constructing the doorway frame, and the strength and rigidity were low, making it easily deformed during transportation and installation.

[Means for Solving the Problems] In order to solve these problems, the present invention provides side members 5, 5' arranged in the vertical direction so as to constitute both side parts, and whose upper edges are connected to the side members. 5, 5', an L-shaped fixture 5a' provided on the back side thereof, and a U-shaped upper edge member 7 provided on the front side of the side members 5, 5'.
The side members 5, 5' are fixed integrally with the fastening part 7a, whose lower end is bent inward, and the side members 5, 5' are arranged horizontally to form an upper edge, and whose lower end is bent to the back side. The upper edge member 7 which is shaped like a letter and forms the fastening portion 7a, the upper edges of the side members 5 and 5', the L-shaped fixture 5a', and the lower part of the U-shaped upper edge member 7. A fastener 8 is formed by integrally fastening a fastening part 7a with one end bent inward, a sill 4 forming a lower edge and arranged horizontally, and a sill 4 provided near the longitudinal end of the sill with one side A bent part 5c is fixed to the threshold and the other side is bent and placed below the upper surface of the threshold, and the side member 5,
5' is fixed to the mounting body 5 via the fixing means 5b.
It is an object of the present invention to provide an entrance/exit device for an elevator hall, which is characterized by comprising: (a).

[Embodiment of the invention] An embodiment of the invention will be described below with reference to FIGS. 3 and 4.

In the figure, the same reference numerals as in FIGS. 1 and 2 indicate corresponding parts, and one side of 5a is arranged on the upper surface of the sill 4 and fixed by the fastening part 6, and the other side is bent downward to form the bending part 5c. The mounting body 5a' is a mounting fixture disposed on the upper edges of the side plates 5, 5' with one side overlapped on the back side and whose lower end extends horizontally in the direction of the sliding door 10.
b is a fixing means made of spot welding and fixes the mounting body 5a and the fixture 5a' to the side members 5, 5'; 7 is a fixing means whose lower end is bent to the back side to form a U-shape; The side wall of the side member 5, 5' has a fastening part 7a arranged so as to overlap with the fixing means 5b on the upper edge of the side member 5, 5', and 8 is a bolt or nut, and the side member 5, 5' upper edge and the upper edge member This is a fastener in which a fastening portion 7a of No. 7 and a fixture 5a' are fastened together.

[Effects of the invention] As explained above, in the present invention, the upper fixing means is a fastening portion formed by bending the lower end of the U-shaped upper edge member 7 inward on the front surface of the side member 5. 7a
and an L-shaped fixture 5a' is provided on the back thereof and is fastened together with a fastener 8.

Therefore, in the entrance/exit device of the present invention, not only the side member 5, the fastening part 7a, and the fixture 5a' are fastened together, but also the lower end of the upper edge part 7 is bent inward to form the fastening part. 7a, it has a U-shaped cross section and has higher rigidity than the conventional example shown in FIG. 2, so there is no risk of deformation during transportation or installation.

Further, according to the configuration of the present invention, the fixing means 5b between the upper edge of the side member and the mounting member 5a' is covered with the lower edge of the upper edge member 7, and the fixing means 5b between the lower edge of the side member and the mounting body 5a.
Because it is designed to be buried in the floor surface of the floor,
The fixing means on the upper and lower edges of the side members 5, 5' can be neatly located without being visible on the floor.
