Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator hall device, and more particularly, to a mounting structure for a car arrival indicator in a hall device in which a curtain plate of a three-sided frame is flush with a hall door that opens and closes an entrance of a hall.

In the conventional elevator hall device, the upper frame corresponding to the curtain plate of the three-sided frame projects toward the hall side from the hall door, and the sound source for notifying the arrival of the car is attached to the upper part of the hanger case (for example, Patent Document 1). reference).

Japanese Utility Model Publication No. 60-180272

In the conventional elevator hall device, since the upper frame projects toward the hall side from the hall door, the sound source installation space can be secured above the hanger case.

However, in an elevator hall device in which the curtain plate is flush with the hall door, the sound source installation space cannot be secured above the hanger case, so the sound source is installed on the back surface of the curtain plate. Then, the sound source is attached to the back surface of the curtain plate through the fixing metal fittings. The fixing member is fixed to the back surface of the curtain plate with an adhesive. At this time, since the area for adhering the fixing member and the curtain plate is small, the adhesive distortion is concentrated on the adhering portion. As a result, joint distortion caused by adhesively fixing the fixing metal fitting locally occurs on the design surface that is the surface of the curtain plate, which is not preferable in terms of design.

Further, by installing the inner plate on the back surface side of the curtain plate and attaching the sound source to the inner plate, it is possible to eliminate the occurrence of local joining distortion on the design surface of the curtain plate. However, since the inner plate for mounting the sound source is required, the curtain plate has a two-layer structure including the design plate and the inner plate. As a result, there is a new problem that the work load during transportation and installation of the landing gear device increases.

The present invention has been made to solve such a problem, and suppresses the occurrence of local joint distortion on the design surface of a curtain plate, and reduces the work load during transportation and installation. The purpose of the present invention is to obtain an elevator landing gear that can be used.

The elevator landing apparatus according to the present invention is installed at a doorway of a landing between a pair of vertical columns spaced apart in the width direction of the doorway with the length direction as a vertical direction and an upper portion of the pair of vertical columns. A curtain plate having a surface facing the landing side as a design surface, a door device disposed on the hoistway side of the curtain plate so as to face the lower side of the curtain plate, and attached to the door device. In addition, a landing door for opening and closing the doorway and a car arrival alarm are provided, and the design surface of the curtain plate and the landing side surface of the landing door are flush with each other. The car arrival indicator is attached to a reinforcing member that is provided on the surface of the curtain plate opposite to the design surface and that enhances the rigidity of the curtain plate.

According to the present invention, the car arrival indicator is not directly attached to the surface of the curtain plate opposite to the design surface. Therefore, local adhesive distortion caused by fixing the car arrival alarm does not occur on the design surface of the curtain. As a result, the deterioration of the design of the curtain plate due to the installation of the car arrival alarm is suppressed. In addition, a new installation member for installing the car arrival alarm is not required, and the curtain plate can have a single structure. This reduces the work load during transportation and installation of the landing gear device.

Embodiment 1.
1 is a perspective view of an elevator landing gear according to Embodiment 1 of the present invention as seen from the landing side, and FIG. 2 is a cross-sectional view of essential parts showing an elevator landing gear according to Embodiment 1 of the present invention.

1 and 2, the doorway 3 is formed in the landing wall 4 so as to communicate with the hoistway 2 from the landing 1. The pair of vertical columns 6 are installed in the doorway 3 with the length direction being the vertical direction and separated in the width direction of the doorway 3. Each of the pair of vertical columns 6 is fixed to the landing wall 4. The curtain plate 7 is, for example, configured in a U shape including a base portion 7a, an upper bending piece 7b, and a lower bending piece 7c. The curtain plate 7 configured in this manner is manufactured, for example, by bending opposite long sides of a rectangular decorative plate in the same direction at a right angle. This increases the rigidity of the curtain plate 7 as compared with the case where the curtain plate 7 is made of a flat plate. The curtain plate 7 is installed between the upper portions of the pair of vertical columns 6 with the upper bent piece 7b and the lower bent piece 7c facing the hoistway 2. As a result, the curtain plate 7 closes the upper side of the doorway 3, that is, the hall ceiling 9 side. The upper bent piece 7b of the curtain plate 7 is located above the landing ceiling 9. The surface of the base 7a of the curtain plate 7 on the side of the landing 1, that is, the surface becomes the design surface.

A reinforcing member 8 for ensuring the rigidity of the curtain plate 7 is arranged on the surface of the base plate 7a of the curtain plate 7 on the side of the hoistway 2, that is, the rear surface. The reinforcing member 8 is manufactured by bending a rectangular flat steel plate into an L shape. The reinforcing member 8 is attached to the back surface of the base portion 7a while being separated in the vertical direction. Each of the reinforcing members 8 has an L-shaped first side bonded and fixed to the back surface of the base portion 7a, and is installed over substantially the entire width direction of the base portion 7a with the L-shaped second side being horizontal. Here, the area for adhering the base portion 7a and the reinforcing member 8 is relatively wide because it covers almost the entire area of the base portion 7a in the width direction, and the adhesive strain is dispersed. As a result, local adhesive distortion does not occur on the design surface of the base portion 7a, and deterioration of the design of the curtain plate 7 is suppressed. Since the reinforcing member 8 is installed over almost the entire area of the base portion 7a in the width direction, the rigidity of the curtain plate 7 is enhanced.

The door device 10 is installed on the hoistway 2 side of the curtain plate 7 so as to face the lower side of the curtain plate 7. Although not shown, the door device 10 includes a landing door frame, a landing door rail, a Noriba door hanger, and the like. The landing door frame is fixed to the hoistway wall 5, and is arranged on the hoistway 2 side below the curtain plate 7 so as to extend in the width direction of the doorway 3. The landing door rail is fixed to the landing door 1 side of the landing door frame and is arranged so as to extend in the width direction of the doorway 3. The landing door hanger is attached to the landing door rail.

The landing door 11 is fixed to the landing door hanger and is hung on the landing door rail. As a result, the landing door 11 is guided by the landing door rail to open and close the doorway 3. The surface of the landing door 11 on the landing 1 side is flush with the design surface of the curtain plate 7.

The car arrival indicator 12 is attached to an L-shaped fixing bracket 13. The fixing fitting 13 is fixed to the second side of the reinforcing member 8 by adhesion or screwing. As a result, the car arrival indicator 12 is attached to the reinforcing member 8 via the fixing bracket 13. The car arrival indicator 12 is located above the door device 10 on the back surface side of the base portion 7 a of the curtain plate 7.

A fireproof iron plate 14, which is a fireproof cover, is fixed to the hoistway wall 5 and closes the upper space of the doorway 3. Although not shown, a fireproof iron plate is fixed to the hoistway wall 5 to close spaces on both sides of the doorway 3 in the width direction and further a lower space of the doorway 3. The inspection port 15 is formed in a portion of the fireproof iron plate 14 that closes the upper space of the doorway 3 and faces the car arrival indicator 12. The cover 16 is detachably attached to the fireproof iron plate 14 and closes the inspection port 15.

The landing device configured as described above can notify the passengers at the landing 1 of the arrival of the car by voice from the car arrival notification device 12. Further, the hall apparatus can notify the passengers of the hall 1 of the information about the opening and closing of the hall door 11 by voice from the car arrival notification device 12. At the time of maintenance of the car arrival notification device 12, an operator removes the cover 16 and performs maintenance of the car arrival notification device 12 through the inspection port 15.

According to the first embodiment, since the landing door 1 side surface of the landing door 11 and the design surface of the curtain plate 7 are flush with each other, the door device 10 is installed close to the curtain plate 7. .. Further, a fireproof iron plate 14 is installed on the upper side of the door device 10. The car arrival indicator 12 is installed at a position above the door device 10 on the back surface of the base 7a of the curtain plate 7 to avoid interference with the door device 10.

The car arrival indicator 12 is attached to a reinforcing member 8 for securing rigidity installed on the back surface of the base portion 7a of the curtain plate 7 via a fixing bracket 13. The local adhesive distortion due to the attachment of the fixing fitting 13 occurs in the reinforcing member 8 and does not occur in the design surface of the base portion 7a. As a result, the design surface of the base 7a of the curtain plate 7 has no local joint distortion, and the designability of the curtain plate 7 is ensured. Since the reinforcing member 8 for securing the rigidity of the curtain plate 7 also serves as the member for installing the car arrival indicator 12, it is not necessary to form the curtain plate 7 into two pieces. Therefore, since the curtain plate 7 having a one-piece structure can be adopted, the work load during transportation and installation of the hall apparatus is reduced.
