Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to an elevator hall system using a self-supporting hoistway tower, which is mainly installed and used in private residences and the like.

(Prior art) Conventionally, home elevators installed and used in private residences (2- to 3-story houses) are made of wood and are weaker than ordinary elevators in buildings, etc., and have to bear the load of the elevator. Since this is difficult, it is necessary to install a free-standing hoistway tower such as a highly rigid steel tower framed by a steel frame.

An overview of this elevator system is shown in Figure 3. In the figure, 1 is a free-standing hoistway tower, which is a highly rigid steel tower framed by a steel frame, and a car 2 is movable up and down within this free-standing hoistway tower 1 via left and right guide rails 3. In addition, a rope 4 and sheave 5 for suspending the car 2, a winding drum hoist 6 for hoisting and unwinding the rope 4 to drive the car 2 up and down, and the like are also provided. All of the elevator equipment is assembled into one unit, including landing thresholds 8 that guide the landing doors 7 so that they can be opened and closed, corresponding to the landing entrances on each floor of the building. The self-supporting hoistway tower 1 is erected within a building independently of the building, so that the elevator load is not borne by the building at all.

(Problem to be solved by the invention) By the way, in the above-mentioned home elevator, the elevator load is not applied to the building at all, and the hoistway and the building side collide and are damaged due to vibration due to earthquakes or strong winds. In order to avoid the burden, the free-standing hoistway tower 1 is erected independently with a slight gap from the building side. For this reason, a gap is created between the landing sill 8 provided on the free-standing hoistway tower 1 and the landing entrance floor (not shown) on the building side, which not only looks very unsightly, but also allows small items to be carried through the gap. There were problems such as getting stuck in the hoistway, or dropping the wheels when using a wheelchair.

The present invention was developed in view of the above circumstances, and uses a self-supporting hoistway tower that does not place any elevator load on the building and can prevent damage caused by collision between the hoistway and the building side even if it vibrates due to earthquakes or strong winds. However, the gap between the landing sill on the free-standing hoistway tower and the landing entrance floor on the building side can be easily covered up, giving it a very good appearance and preventing small items from falling into the hoistway or the wheels of wheelchairs. To provide an elevator hall device which can eliminate inconveniences such as falling objects.

[Structure of the invention]

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a gap between a free-standing hoistway tower equipped with a landing sill that guides the landing door so that it can be opened and closed, and the landing entrance on the building side. In the elevator landing apparatus which is installed vertically, an engaging part is provided at the landing sill of the free-standing hoistway tower, one side part is slidably engaged with the engaging part in the longitudinal direction and the other side is slidably engaged with the engaging part. The main feature is that the section is equipped with a gangplank that spans over the floor of the landing on the building side.

(Function) With the above configuration, in the elevator landing apparatus of the present invention,
The gap between the landing sill of the freestanding hoistway tower and the landing entrance floor on the building side can be covered with a gangplank, giving it a very good appearance.
This eliminates inconveniences such as dropping small items into the hoistway or dropping wheelchair wheels. In addition, the above-mentioned gangplank is easy to install because it only engages one side with the retaining part of the landing sill of the free-standing hoistway tower and allows the other side to cross over the landing entrance floor on the building side. At the same time, the - side part can be slid in the longitudinal direction relative to the engagement part of the landing sill, and the other side part can be slid onto the landing entrance floor on the building side, so that the elevator load is not borne by the building at all. Even if vibrations occur due to earthquakes or strong winds, unreasonable force will not be exerted on the hoistway and the building side.

(Example) An example of the present invention will be described below with reference to FIGS. 1 and 2. In the figure, the same components as those shown in FIG. 3 are given the same reference numerals to simplify the explanation.

As in the past, the free-standing hoistway tower 1, which is made of a highly rigid steel tower framed by a steel frame, absorbs all the elevator load from the building 11.
It is erected independently from the building 11 side with a slight gap A in order to not place any burden on the building 11 side and to avoid colliding with the building 11 side in the event of vibration due to an earthquake or strong wind. This self-supporting hoistway tower 1 is provided with a landing sill 18 that guides the landing door 7 so that it can be opened and closed. As a result, the landing sill 18 provided in the self-supporting hoistway tower 1 is also attached to the building 1 in the same manner as before.
A gap A is created between the landing entrance 12 on the first side and the tip of the floor 13. If left as is, it will not look good, and there is a risk that small items may fall into the hoistway or the wheels of a wheelchair may fall through the gap.

Therefore, first, an engaging portion 19 is provided on the landing sill 18. In other words, the landing sill 18 is the self-supporting hoistway tower 1 as shown in the figure.
It is fastened and fixed to the upper surface of a sill receiving frame 20 made of channel material or the like using a plurality of bolts 21, and is made of extruded aluminum or the like, and has a bolt groove 18a in the center into which the head of each bolt 21 slides. A state in which one of the engaging portions in the shape of a lip groove is opened backwards on the outer edge facing the tip of the floor 13 of the landing entrance 12 of the building 11. It has over the entire length in the longitudinal direction.

One side part engages with the lip groove-shaped engagement part 19 of this landing sill 18, and the other side engages with the floor 1 of the landing entrance 12 on the building 11 side.
3. A gangplank 22 is provided on the top surface. This gangplank 22 is a band plate-like piece made of a material of the same color as the landing sill 18 in order to unify the design, and has a hook-shaped (L-shaped) engagement protrusion on the side. 22a over the entire length in the longitudinal direction, and is engaged with the lip groove-shaped engagement portion 19 of the landing sill 18 so as to be slidable in the longitudinal direction and prevented from being removed in the front-rear direction perpendicular thereto. . The gangplank 22 is now attached to the landing sill 18 so that it is flush with the top surface. The other side of the gangplank 22 is tapered and has a thin wall, so that the landing entrance 12 on the building side 11
A hook is placed on the upper surface of the floor 13 so that it can slide. The length of this gangplank 22 is the length of the building side 11.
is made equal to the frontage dimension of the landing entrance 12 of the landing entrance 12.
Both ends are joined to the left and right entrance/exit frames 14 of.

Therefore, if the elevator has the above-mentioned configuration, the landing sill 18 of the free-standing hoistway tower 1 and the floor 1 of the landing entrance 12 on the building 11 side
3 can be covered with the gangplank 22, so it looks very good and eliminates inconveniences such as dropping small items into the hoistway or dropping the wheels of the wheelchair.

The gangplank 22 is also connected to the landing sill 18 of the free-standing hoistway tower 1.
The hook is simply passed so that one side part engages with the lip groove-shaped engagement part 19 and the other side part is placed on the upper surface of the floor 13 of the landing entrance 12 on the building 11 side, so the installation is easy. In addition, one side of the gangplank 22 is connected to the engaging portion 1 of the landing sill 18.
9, and the other side is slidable in the longitudinal direction relative to the building 11.
Since it is possible to slide the top surface of the side landing entrance 12 onto the floor 13, not only will the elevator load not be borne by the building 11 at all, but also the free-standing hoistway tower 1 and the building 1 will be protected against the effects of earthquakes and strong winds.
Even if the bridge plate 22 vibrates so as to move relative to the first side, the
slides in the left-right direction against the landing threshold 18, and in the front-back direction against the upper surface of the landing entrance 12 floor 13 on the building 11 side, so that excessive force is applied to the free-standing hoistway tower 1 and the building 11 side. You will not be allowed to work.

In the above embodiments, the self-supporting hoistway tower 1 is made of a steel tower, but it is also possible to use a self-supporting hoistway tower made of non-ferrous metal or concrete.

〔Effect of the invention〕

Since the present invention is configured as described above, it uses a self-supporting hoistway tower that does not place any elevator load on the building and can prevent damage caused by collision between the hoistway and the building side even if it vibrates due to earthquakes or strong winds. Even if there is, the gap between the landing sill on the freestanding hoistway tower and the landing eye on the building side can be easily covered, giving it a very good appearance and preventing small items from falling into the hoistway or getting into the wheelchair. This has the effect of eliminating inconveniences such as wheels falling in.
