Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to an elevator landing device that is integrally assembled and unitized in a factory.

[Conventional technology]

In general, an elevator hall system consists of a three-sided frame that forms an entrance, a hanger case and threshold fixed above and below the three-sided frame, a door that opens and closes the entrance, and other equipment such as an opening/closing mechanism. Equipment needs to be installed with the required precision in the landing area of the elevator installation site, but recently the overall installation period for elevators has been increasingly shortened, and it is also difficult to maintain the required installation accuracy at construction sites with poor working environments. Because it is difficult to obtain such a system, the entire device is currently assembled as a unit at a factory and then transported to the installation site and installed. A conventional example in which the elevator landing apparatus is unitized for transportation is shown in FIGS. 4 and 5. As a prior art similar to this, for example, there is a technology disclosed in Japanese Patent Application Laid-Open No. 13155/1983. In the figure, a three-sided frame 1 forms an entrance 2 on the hall side of the elevator, and forms the upper side and left and right sides of the entrance. A hanger case 3 is fixed to the upper side of the three-sided frame 1. The panogar case 3 houses unillustrated opening/closing mechanisms for the left and right landing doors. A hanger case fixing fitting 5 is attached to the side plate 3a of the t'r case 3 with bolts 4. This hanger case fixing bracket 5
The elevator landing device is fixed to the landing of the building. A threshold 6 is fixed to the lower end of the left and right sides of the three-sided frame 1. This threshold 6 has a hole 8 through which a jack bolt 7 passes, a tapped hole 11 into which a bolt 10 for attaching a lower fixing fitting 9 (to be described later) is screwed, and further to the left. A groove 6a is formed in which a landing door 12.12 that is opened and closed on the right is guided. Into this groove 6a, the lower end of each landing door 12, which is suspended by an opening/closing mechanism (not shown) housed in the nozzle case 3 and opens/closes, is inserted and guided. In this state, each landing door 12
is simply suspended by an opening/closing mechanism and guided to the sill 6, so it is not integrated into the elevator landing system as a whole, and some type of fixing hardware is required when transporting it from the factory to the site. . Therefore, the lower surface of the hanger case 3 and each landing door 12
An upper fixing fitting 13 is provided for fixing the upper front end of the. This upper fixing metal fitting 13 has a cross-sectional shape 9 and is fixed to the hanger case 3 and each landing door 12 with bolts 14. Further, a lower fixing metal fitting 9 is provided for fixing the front lower end of each landing door 12 and the upper surface of the sill 6. The lower fixing metal 9 has an angular cross section and is fixed to each of the landing doors 12 and the sill 6 by bolts 10, respectively. bolt 10
Threaded holes 15, 11 are provided in the upper and lower fixing fittings 13, 9, respectively, for passage therethrough. Note that the jack bolt 7 is screwed in through the screw hole 16 drilled in the lower fixing metal 9 and the penetrating hole 8 provided in the sill 6, and by adjusting the jack bolt 7, the elevator hall equipment can be placed in the transport unit state. If the product is installed as-is, centering is performed on site, or in other words, position adjustment is performed during installation. As described above, the elevator landing device is made into a transportation unit by attaching the upper fixing bracket 13 and the lower fixing bracket 9 that are long in the width direction of the three-sided frame 1 and fixing each landing door 12, and the installation is carried out to the site and installed. be done.

[Problem to be solved by the invention]

The conventional elevator landing device is configured as described above, but the upper fixing fitting 13 is used to form a transportation unit.
The lower fixing brackets 9 are heavy items that are long in the width direction of the three-sided frame 1, and are no longer needed after the landing equipment is installed on site. Must be stored temporarily. For this reason, a large amount of cost was required for storage space and transportation for return. Furthermore, since the upper fixing metal fittings and the lower fixing metal fittings are heavy objects, the weight of the entire conveyance unit of the elevator landing apparatus increases, making conveyance and cargo handling extremely difficult. This invention was made in view of the above-mentioned problems, and it is possible to reduce the weight and size of the fixing fittings used to unitize the units, eliminate the need to return them to the factory, and eliminate the need to significantly increase the weight of the entire transport unit. The object of the present invention is to obtain an elevator landing device equipped with metal fittings.

[Means to solve the problem]

This invention includes a three-sided frame forming the upper side and left and right sides of the doorway, a hanger case fixed to the upper side of the three-sided frame, a sill fixed to the lower end of the left and right sides of the three-sided frame, and an opening/closing mechanism inside the hanger case at the upper end. In an elevator landing device having a landing door that is suspended by a door and whose lower end is guided to the sill, a side lower end fixing fitting that fixes the upper end of the side surface of the landing door in a fully open state and the side surface of the hanger case; A side lower end fixing fitting is provided for fixing a side lower end of the landing door in a fully open state and a rear end surface of the sill.

[For production]

According to the elevator landing device of the present invention, when the landing door is fully opened, the upper end of the side surface of the landing door almost coincides with the hanger case side, and the lower end of the side surface of the landing door almost coincides with the short side of the sill. Therefore, by using side fixing fittings for fixing these side surfaces, it is possible to form an elevator landing apparatus into a transportation unit using small side fixing fittings.

【Example】

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. The same parts as in FIGS. 4 and 5 showing the conventional example are given the same reference numerals. The three-sided frame 1 is arranged at the entrance/exit of the elevator hall and forms the upper side and left and right sides of the passenger entrance/exit 2. A hanger case 3 is fixed to the upper side of the three-sided frame 1. Further, a threshold 6 is fixed to the lower end of the left and right sides of the three-sided frame 1. Further, the upper ends of the left and right landing doors 12 are suspended by an opening/closing mechanism within the hanger case 3, and perform opening/closing operations. The lower end of each landing door 12 is guided in a groove 6a provided in the sill 6. In order to convert such an elevator landing device into a transportation unit, each landing door 12 is fully opened, and the upper end of the side surface of each landing door 12 in the fully opened state and the side surface of the hanger case 3 are fixed at the lower end of the side surface. It is fixed with a metal fitting 21. Further, the lower end of the side surface of each landing door 12 in the fully open state and the short side surface of the sill 6 are both fixed with the fixing metal 22 for the upper end of the side surface. In this embodiment, the side plate 3a of the conventional hanger case 3 is used as the side upper end fixing metal 21. Further, for both the side upper end fixing metal 22, a joint which is a short metal fitting having an L-shaped cross section is used. This will be explained in more detail below.

24 is inserted and screwed onto the nut via the spacer 23. By tightening the bolts in this manner, the landing door 12 is firmly fixed to the hanger case 3. The side plate 3a of the hanger case 3 has conventionally existed, and since this side plate 3a also serves as a side lower end fixing fitting, no new fixing fitting is required. Next, fixing of the lower end of the side surface of the landing door 12 in the fully open state will be explained. This fixation is performed by a fixing fitting 22 which is a joint. An enlarged view of this part is shown in FIG. A groove 6a for guiding the landing door 12 is not formed in the sill 6 as in the conventional case. A hole 31 for dropping dirt is formed at the bottom of the groove 6a. In addition, the portion of the sill 6 where the groove 6a is not formed, that is, the inside of the thick wall portion, has the sill 6.
A groove 32 running in the longitudinal direction is formed. This groove 32
The bolt 33 is inserted, and the \rad 34 of the bolt 33 is
are engaged and can slide in the longitudinal direction of the groove 32. The tip of this bolt 33 is inserted into an elongated hole 35 provided in one side 22a of the 5-shaped fixing metal fitting 22 having the cross-sectional shape, and a nut 36 is screwed into the fixing metal fitting 22 from below. There is. Next, fixing of the fixing fittings 22 and the landing door 12 will be explained. A long hole 37 is provided on the other side 22b of the figure 5 shape of the fixing bracket 22, that is, on the vertical side, and a hole is provided at the lower end of the side surface of the landing door 12 at a position opposite to the long hole 37. It is being A nut 38 is fixed to the edge of this hole. A spacer is provided between the elongated hole 37 and the hole, and the bolt 39 is inserted from the outside of the fixing fitting 22 and the nut 3 is inserted.

Note that the conventional jack bolt 7 utilizes the hole 31 provided at the bottom of the groove 6a for removing dust, and no new hole is made specifically for the jack bolt 7. That is, by providing holes 3 on both ends of the sill 6 for removing dirt, inserting jack bolts 7 from above and screwing nuts from below, centering work of the elevator landing equipment can be performed in the same way as in the past. It can be performed. In this embodiment, each landing door 12 and the sill 6 are fixed as follows.
Since this is done on the side of each landing door 12 and the end side of the sill 6, it can be done with sufficient strength even with small joints of fixing metal fittings. Therefore, when fixing to the landing door at the middle of the sill 6 as in the conventional case, there is no need to use a large fixing metal fitting. Further, in this embodiment, the upper end of each landing door 12 is fixed using the side plate 3a of the hanger case 3, which has conventionally existed, but in other embodiments, it is also possible to provide another metal fitting, for example, a sheet metal. The side of the landing door 12 and the hanger
It is fixed to the side surface of the case 3, and can be fixed with sufficient strength even with a small metal fitting. Further, according to this embodiment, there is no need to provide bolt holes for fixing on the top surface of the sill 6, and the holes for the jack bolts are provided at the bottom of the groove 6a, so that the bolt holes that are unattractive can be placed on the top surface of the sill 6. There will be no need to drill holes. Therefore, it is an excellent threshold for Q craftsmanship.

【Effect of the invention】

As described above, according to the elevator landing device of the present invention, since the landing door is fixed in the fully open state, the upper end of the side surface of the landing door and the side surface of the hanger case can be fixed, and the lower end of the side surface of the landing door and the sill can be fixed. The end and side surfaces can be fixed. Therefore, even with a small fixing metal fitting, the fixing can be performed with sufficient strength. Therefore, it is no longer necessary to use large upper and lower fixing metal fittings that are heavier than the conventional ones. This eliminates the need to temporarily store or return the removed fixing brackets at the installation site after installation. Furthermore, since it can be fixed with small fixing metal fittings, there is no need to increase the overall weight of the transport unit so much, and transport and cargo handling become easier.
