Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an elevator entrance/exit device that is integrally assembled and unitized in a factory, and particularly to an elevator entrance/exit device suitable for shipping, transportation, and on-site delivery.

Generally, the entrance/exit device of this kind of elevator consists of an entrance/exit pillar,
It consists of equipment such as the sill, door, and opening/closing mechanism, and each of these parts and equipment must be installed at the entrance/exit of the elevator installation site with the required precision, but recently the installation period for the entire elevator has been shortened. In addition, achieving the required installation accuracy at construction sites with poor working environments requires extremely advanced technology, and small parts are easily lost at such sites. Therefore, especially for opening/closing mechanisms that have many small parts and require high-precision assembly, we assemble them in advance at the factory and transport them to the installation site in a unitized state. There is.

A conventional unitized elevator entrance/exit device of this type is shown in FIGS. 1 to 3.

1 to 3, 1 is a door for opening and closing the doorway 2, 1 is an opening/closing mechanism unit that is fixed to the wall 4 above the doorway 2 and operates the door 1, and 5 is a lower part of the doorway 2. This is a threshold that is fixed to the floor 6 of the room 1 and guides the lower end of the room 1.

Further, 11 is a banger case with a cross-sectional shape, 12 is a rail fixed to this banger case 11, and 13 is the above-mentioned 1
The banger 14, which is suspended and rolls on the rail 12, is comprised of a latch 14a fixed to the banger case 11, and a latch 14b pivotally supported by the banger 13 and engaged with the latch 14a. The locking device IJ- is connected to the opening and closing of the elevator car door (not shown), and is an engagement device for engaging and disengaging the locking device L4 through the connecting rod 15affi and opening and closing the door 1. , 16 have a cross-sectional shape and are attached to the case 11, and the rails 12. This is a cover that covers the banger 13, the locking device 14, and the like.

However, the opening/closing mechanism unit in the conventional elevator entrance/exit device constructed in this way forms a kind of outer frame.The banger 13 and the engagement device 15 are placed under the ringer case 11 and the cover 16. Because some parts of the mechanism protrude, a large number of auxiliary materials are required to prevent the protruding mechanical parts from being deformed or damaged during transportation after being assembled integrally. In addition to this, it is also necessary to prepare storage frames at the installation site until the work begins, which not only results in higher costs, but even with such strict consideration. However, it is unavoidable that the product will be slightly deformed due to being hit by other objects, thus requiring installation and modification at the time of installation, which increases the time required for the work.

In view of these conventional circumstances, the present invention provides an elevator entrance/exit device in which a side plate is provided as an attachment to a pre-assembled opening/closing mechanism unit to prevent the protruding portion from interfering with other objects, and a stacking device is provided on the side plate. The present invention provides an installed elevator entrance/exit device.

Hereinafter, one embodiment of the entrance/exit device according to the present invention will be described in detail with reference to FIGS. 4 to 7.

4 to 6 show the opening/closing mechanism unit according to this embodiment.

In these FIGS. 4 to 6, the same reference numerals as in FIGS. 2 and 3 represent the same or corresponding parts,
In this invention, a pair of side plates 22 and 23 are provided on both end surfaces of the case 11 to form an opening/closing mechanism unit L1,
The above-mentioned −
・Nger case 11. -・Ngar13. All the equipment such as the locking device 11 and the cover 16 are included, and as the side plates 22 and 23, for example, a steel plate with a cross-sectional shape is used as is clear from the figure.
・It is welded to the ring case 11.

Further, a first stacking tool 22a having a U-shaped cross section and a groove formed by the U-shaped portion is located at a position offset to one edge of the upper portion of each of the side plates 22,23.

23a is welded with the opening of the groove facing upward and with the groove aligned with the surface direction of the side plate.

Then, at a position offset to the other edge of the upper part of each side [22, 23], second stacking tools 22b, 23b each having a U-shaped cross section and a groove formed by the U-shaped portion are bent at right angles.
However, the openings are welded with one of the grooves bent upward at right angles aligned with the direction of the grooves of the first stacking tools 22 and 23, and each of these stacking tools 2
2a, 22b and 23a, 23b receive the lower edge of each side plate of the upper layer unit when a plurality of opening/closing mechanism units 1 are stacked in the vertical direction, and as shown in FIG. 7 when viewed from the end surface side, This makes it possible to transport or store a large number of units without using additional auxiliary materials.

Therefore, according to the present invention, by providing a pair of sides [22, 23 on both end surfaces of the banger case 11, the protrusion of the equipment part can be covered, so that transportation and
In addition to protecting each protruding part during loading and unloading to avoid deformation and damage, it is also possible to install it on site, for example, by keeping it upright as shown in Figure 5, or by placing the cover 16 side down. , storage is possible without the need for an equivalent underframe, and as a result, there is no need to consider modifications, installation,
Adjustment time can be greatly reduced and high-quality door opening/closing performance can be achieved.

Also, since both end faces of the engine case 11 are closed by the side plates 22 and 23, the rigidity of the engine case 11 itself against twisting is increased, and therefore the material used can be made thinner than before. This makes it possible to reduce production costs.

In the above embodiment, the side plates 22 and 23 are fixed to both end surfaces of the case 11 by welding, but they are constructed so that they can be removed as a jig from the factory until the end of the installation process. Of course, once the installation is complete, it can be disposed of or returned to the factory for reuse.Also, although the opening/closing mechanism unit on the landing side has been explained above, it can be implemented on the opening/closing mechanism unit on the car side. The same effect can be obtained even if

As described in detail above, the present invention configures an opening/closing mechanism unit by providing a pair of side plates on both end faces of the case to protect the protrusion of the device from the outside. This device has the advantage that it can effectively prevent deformation and damage to the device parts from the factory to the end of installation, and that the structure is extremely simple and can be provided easily and inexpensively.

Further, since a stacking device is provided on the side plate of the device configured in this way, it has the effect that a large number of units can be stacked and transported or stored without using any additional auxiliary materials.
