Description

TECHNICAL FIELD The present invention relates to a lifting device for a storage box that is installed in an elevator car and stores articles for disaster prevention and emergency.

Due to the occurrence of an earthquake or the like, there have been reports of so-called trapped damage in which passengers are trapped in elevator cars. Elevators are usually set to make an emergency stop at the nearest floor, open the doors, and wait when a certain level of seismic intensity is exceeded. In addition, depending on the elevator, in the event of an emergency stop, it is possible to communicate with the control room and control center inside and outside the car via an interphone to avoid being trapped.

If an epicenter earthquake occurs in a large city, it is expected that many elevators will be stopped almost simultaneously, and confinement will occur in many elevators. In addition, an earthquake with a large seismic intensity can lead to congestion of telephone lines, wide-area power outages, and traffic jams. is expected to last for a long time. It has been reported that more than 10% of the total number of confined reactors were confined for more than 3 hours due to past earthquakes with large seismic intensity.

In situations where it takes a long time to be rescued from confinement, portable toilets and drinking water such as PET bottles are provided so that trapped people can wait for rescue without harming their health. It is recommended to install a storage box for disaster prevention in an elevator car, and various types have already been proposed.

Conventional storage boxes for disaster prevention, as shown in FIG. 2 of Patent Document 1, are installed on the floor inside the car. From a security point of view, it cannot be opened easily.

However, since the conventional storage box for disaster prevention in the car of the elevator is installed on the floor surface, a dead space is generated in the car, which reduces the space available to passengers. In addition, since it is supposed to avoid making holes in the wall or floor inside the elevator car to install the storage box, it is difficult to prevent the storage box from being taken out, and it is constantly the target of theft and pranks. fraught with danger.

Therefore, the inventors of the present invention did not install the storage box on the floor surface in the car, but placed it above the head of a person of normal height, about 2 m higher than the floor near the wall surface in the car. , the generation of dead space in the car can be suppressed as much as possible, and the risk of the storage box becoming the target of theft or pranks can be reduced.

An embodiment of a storage box lifting device installed in an elevator car will be described below with reference to the drawings.
As a basic configuration of the lifting device 1, as shown in FIG. A lifting plate 11 that can hold a storage box that can be used, and a hoisting machine 5 that can raise or lower the lifting plate 11 or hold it at a predetermined height position (see FIG. 2). ). A rail 12 is laid on the pole 2, and the elevating plate 11 moves up and down on this rail.

As shown in FIG. 1(b), two poles 2 are installed between the ceiling 100 and the floor 200 inside the car along the wall surface inside the car. Contact members 3 and 4 are attached to the upper and lower ends of the two poles, respectively. The distance between the two poles 2 may be determined in consideration of the width of the lifting plate 11 and the like.

The ceiling height in the elevator car is usually about 2000 to 2300 mm, and the length of the pole 2 is usually longer than 2000 mm. It can also be formed by a plurality of plug-in pipes. The pole 2 having a length slightly exceeding 2000 mm can be formed with three pipes having a length of around 700 mm (see FIG. 1(b)). The pipe is preferably a rectangular square pipe with a hollow cross section, and for example, a steel or aluminum square pipe with a cross section of about 30 mm×30 mm can be used. As the square pipe, it is preferable to use a square pipe with rounded corners.

The pole 2 may be manufactured to have the same length as the ceiling height inside the elevator car, but since the ceiling height inside the elevator car is not always constant, the height of the pole 2 can be adjusted. It is preferable to use
As the pole 2, it is possible to use a so-called tension rod that is fixed by applying pressure to opposing planes through expansion and contraction and fixing. The tension rod has a built-in expansion and contraction means in advance, but if not, the pole 2 having a mechanism for adjusting the height at the lower end can be used. In either case, the pole 2 can be installed while being pressed against the ceiling surface and the floor surface. The pole 2 having a mechanism for adjusting height will be described later.

A contact member 3 is provided on the upper ends of the two poles 2 . Therefore, the upper ends of the two poles 2 are connected by the contact member 3 . The contact member 3 comes into contact with the ceiling 100 when the two poles are installed along the wall surface inside the car.
Similarly, the lower ends of the two poles 2 are also provided with contact members 4 across the lower ends of the two poles 2 . Therefore, the lower ends of the two poles 2 are connected by the contact member 4 . The contact member 4 comes into contact with the floor 200 when the two poles are installed along the wall surface inside the car.

In order for the pole 2 to stand along the wall surface inside the elevator car, the abutting members 3 and 4 may protrude from the front side of the pole 2 like eaves. It is desirable that something like eaves is not formed as much as possible.
Here, the rear surface and the front surface of the pole 2 refer to the surface of the pole 2 facing the wall surface and the surface facing the inside of the car, respectively, when the pole 2 is erected along the wall surface inside the car. pointing to

When the upper and lower ends of the two poles 2 are connected by the contact members 3 and 4, the rectangular framework formed by the two poles 2 and the two contact members 3 and 4 is crushed and deformed into a parallelogram. It becomes difficult and becomes strong. As a result, the two poles can be easily arranged between the ceiling and the floor along the wall surface, and can be installed in a shorter time than when the two poles 2 are individually installed one by one.
The surface of the contact member 3 contacting the ceiling 100 and the surface of the contact member 4 contacting the floor 200 are usually made of a cushioning material.

A hoisting machine 5 is installed on the upper part of the two poles 2, and the hoisting machine 5 raises and lowers an elevating plate 11 on which a storage box can be hung, and holds it at a predetermined height position. be able to.
As shown in FIGS. 1A and 2, the hoisting machine 5 includes a case 8 installed on the front side of the top of the two poles 2 and a rotating shaft (hoisting rod) rotatably supported by the case 8. ) 6 and a pulley 7 fixed to one end of the rotating shaft 6 . 1A and 2, the cover of the case 8 is removed.

A hoisting chain 9 (usually forming a loop) is hung around the pulley 7 and hangs down along one pole 2 (the left pole 2 in FIG. 1(a)). By pulling down one of the looped parts of the chain 9, the pulley 7 rotates forward or backward, and at the same time, the rotating shaft 6 fixed to the pulley 7 rotates forward or backward. can let

One end of a belt 10 is attached to the central portion of the rotating shaft 6 . The other end of the belt 10 is connected to the top of the lifting plate 11 . Therefore, by rotating the rotating shaft 6, the lifting plate 11 can be moved up and down. FIG. 1( a ) shows a state in which the belt 10 is wound up by the rotation of the rotating shaft 6 and the lifting plate 11 is positioned above the pole 2 . When it is further rolled up, the upper edge of the elevator plate 11 (in actual use, the upper edge of the storage box 16 hooked to the elevator plate 11) comes into contact with the lower edge of the cover (not shown) of the case 8 and rises. stops. When the rotation shaft 6 is rotated in the opposite direction from this state, the lift plate 11 descends. Further, when the rotation of the rotary shaft 6 is stopped, the movement of the lift plate 11 is stopped and the lift plate 11 remains at the same position (height).

On the front surface of each of the two poles 2, as shown in FIG. 1(a), a rail 12 is laid downward from the vicinity of the case 8 of the pole 2. As shown in FIG.
The rail 12 may be laid near the lower end of the pole 2, but the storage box hooked on the lifting plate 11 does not need to be lowered to near the floor surface, and can be removed from the lifting plate 11 around the waist of the person. to a height of about 1000 mm from the floor. In this case, the lower end surfaces of the two rails must be closed so that the lift plate 11 is not further lowered and removed. In FIG. 1( a ), a horizontal member 13 is installed between two poles 2 to block the lower end surface of the rail 12 .

The rail 12 can be made of a shape member called a C-channel having a lip-shaped cross section (a shape in which lips protrude from both sides of the groove). On the other hand, on the rear surface of the lift plate 11 near the ends in the width direction, there are formed protrusions that fit into the grooves of the rails 12 and do not come off. can be moved up and down along the rail 12 by being guided by the

A plurality of hook members 14 for hooking are attached to the front side surface of the lifting plate 11 . In the embodiment shown in FIG. 1( a ), four hook members 14 are attached near the four corners of the lift plate 11 .
On the other hand, as shown in FIG. 10, a hook member 16 for hooking onto a hook member 14 is attached to one side of a storage box 15 for disaster prevention or the like, so that the storage box 15 can be hooked to the lifting plate 11. is now possible. The storage box 15 is not limited to the type of handbag that can open on both sides as shown in FIG.
Therefore, if the storage box 15 is hooked to the lift plate 11, the storage box 15 hooked to the lift plate 11 can be lifted by pulling down the chain 9 and rotating the pulley 7 forward or backward. can.

Next, the pole 2 provided with a mechanism for adjusting the height at the lower end will be described.
As a mechanism for adjusting the height, two mechanisms, a height adjustment mechanism 20 and a height fine adjustment mechanism 21, are used together. A mechanism 21 performs fine height adjustment for finishing.

The height adjustment mechanism 20, as shown in FIG. can be configured by adjusting
A hole (not shown) is formed in the upper end of the height adjusting pipe 22 and a V-shaped spring fitting (not shown) is inserted therein. A fixing projection is formed on one of the open portions of the spring metal fitting, and this projection fits into the hole and presses down with the elasticity of the spring.
On the other hand, a plurality of holes 23 are formed in a vertical line at predetermined intervals on the side surface of the lower end of the pole 2 into which the height adjusting pipe 22 is inserted. The height can be adjusted by fitting the projection of the spring fitting in the height adjusting pipe into one of the holes 23 . The projection is fitted into the hole 23 at the bottom in FIG. 3(a) and the hole 23 at the top in FIG. 3(b). Such spring fittings are commercially available as pipe joint clips. For example, if 6 to 9 holes 23 are provided at the lower end of the pole 2 at intervals of 35 mm, the height can be adjusted within a range of about 175 to 280 mm by changing the insertion amount of the height adjusting pipe 22. can be done. In the one shown in FIG. 3, six holes 23 are drilled.

The height fine adjustment mechanism 21 can be configured by combining a tubular member 24 having a female thread and a male threaded member 25 having a rod-shaped portion having a male thread.
As shown in FIG. 4, a fine height adjustment mechanism 21 is provided at the lower end of a height adjustment pipe 22 used in the height adjustment mechanism 20. As shown in FIG.

The cylindrical member 24 has a female thread formed inside the cylinder.
The upper portion of the tubular member 24 is inserted into the lower end of the height adjusting pipe 22 and the lower portion of the tubular member 24 is exposed from the lower end of the height adjusting pipe 22 .
On the other hand, the male threaded member 25 is a member comprising a rod-shaped portion having a male thread and the abutment member 4 at the lower end of the rod portion that contacts the floor 200 . The male thread of the rod-like portion is adapted to fit into the female thread of the tubular member 24 .

A partition plate 26 is fixed inside the height adjusting pipe 22 so as to close the cross section. An iron plate or an aluminum plate can be used for the partition plate 26, and can be attached and fixed by welding or the like.
A hole is formed in the central portion of the partition plate 26 , and the rod-shaped portion of the male screw member 25 can pass through this hole, but the tubular member 24 cannot pass through the partition plate 26 .

As shown in FIG. 4, the upper end of the tubular member 24 is inserted from the lower end of the height adjusting pipe 22 and is arranged at a position in contact with the lower surface of the partition plate 26, and penetrates from the outside to the inside of the pipe 22. It is rotatably supported with respect to the pipe 22 by two opposing screw members 27 which are inserted in the same direction. That is, a groove into which the tip of the screw member 27 can be inserted is formed in the outer circumference of the cylindrical member 24, and the screw member 27 is inserted into this groove so that the tip does not touch the bottom of the groove. Two screw members 27 rotatably support the tubular member 24 in a suspended state. The threaded member 27 is inserted into a female threaded ring member 28 that penetrates and is fixed to two opposing pipe wall surfaces of the height adjusting pipe 22 .

Therefore, when the portion of the tubular member 24 exposed from the lower end of the height adjusting pipe 22 is gripped and the tubular member 24 is rotated forward or backward, the rod-shaped portion of the male screw member 25 is pushed into the tubular member 24. By moving up or down in the cylinder, the exposed length of the rod-shaped portion of the male screw member 25 from the lower end of the tubular member 24 can be changed, thereby finely adjusting the height of the pole 2. can.
Since the partition plate 26 is fixed inside the height adjusting pipe 22, the tubular member 24 cannot be moved upward even if the tubular member 24 is held and rotated. The occurrence is reduced and the load applied to the screw member 27 can be reduced.
If the outer diameter shape of the cross section of the portion on the lower side of the cylindrical member 24 is not circular but is a shape that is easy to grip, for example, a hexagonal shape, the cylindrical member 24 can be easily rotated and the height of the pole 2 can be increased. It is easy to fine-tune the depth (see Fig. 5).

Since the lower end of the male screw member 25 is in contact with the floor 200, the contact member 4 is provided at the lower end thereof.
After the pole 2 is installed between the floor 200 and the ceiling 100 in the car by setting the pole 2 to the same height as the ceiling height by the height adjustment mechanism 20, the height of the pole 2 is adjusted by the height fine adjustment mechanism 21. can be fine-tuned to be firmly installed between the ceiling surface and the floor surface in the car. FIG. 5 shows the height adjustment mechanism 20 and the height fine adjustment mechanism 21 provided at the lower end of the pole 2. As shown in FIG.

In the above-described embodiment, the height adjustment device 20 and the height fine adjustment mechanism 21 are used to move the two poles 2 along the wall surface inside the elevator car so that the ceiling surface and the floor surface are brought into contact with the contact members 3 and 4. In addition, if the material of the wall surface in the elevator car is steel, a member with an embedded magnet is attached to the pole 2 and the magnetic force acts to separate the two The pole 2 can be prevented from being peeled off from the wall surface, and can be installed along the wall surface in the car more firmly. An embodiment in which magnets are used to install the poles 2 along the wall surface inside the car will be described below.

In order to install the pole 2 using magnets, a magnet embedding member 31 composed of two types of frames in which magnets 30 are embedded can be used. One is a base frame 32 located between two poles 2 (see FIG. 6), and the other is an auxiliary frame 33 attached to both ends of the base frame 32 (see FIG. 7). Therefore, the magnet embedding member 31 is composed of one base frame 32 and two auxiliary frames 33 (see FIG. 8).

A magnet 30 is embedded and exposed on one side of the base frame 32 . In the one shown in FIG. 6, eight round magnets are embedded. The shape of the magnet 30 and the number of magnets are not limited to those shown in FIG.
Holes 34 are formed in both ends of the base frame 32, and in FIG. 6, two holes 34 are formed in each end. The base frame 32 and the auxiliary frame 33 are connected as described later by inserting the screws into the holes 34 from the side opposite to the side where the magnets 30 are embedded (the side where the magnets 30 are not exposed). be able to.

A magnet 30 is embedded and exposed on one side of the auxiliary frame 33 . In the one shown in FIG. 7, two round magnets are embedded. The shape of the magnet 30 and the number of magnets are not limited to those shown in FIG.
As shown in FIG. 7(a), plate-like protrusions 35 are formed in the vertical direction on the surface of the auxiliary frame 33 opposite to the surface in which the magnets 30 are embedded (the surface on which the magnets 30 are not exposed). , split into two regions. In one region (the left side in FIG. 7) is formed a protuberance 36 having a circular cross section and having a female screw hole for receiving a screw inserted into the hole 34 at the end of the base frame 32. , a hole 37 is formed in the central portion, and two columnar projections 38 are formed so as to sandwich the hole 37 . The magnets 30 of the auxiliary frame 33 are embedded in the other area.

In the above one region of the auxiliary frame 33, a screw inserted into the hole 34 of the base frame 32 from the opposite side of the magnet exposed surface of the base frame 32 is inserted into a female screw hole of the projection 36 of the auxiliary frame 33. Each end of the base frame 32 and the auxiliary frame 33 are screwed so that the surfaces (the above-mentioned one surface) where the magnets 30 are exposed on both the base frame 32 and the auxiliary frame 33 are on the same side. , a magnet embedded member 31 is formed (see FIG. 8).
On one side (the side where the magnets are exposed) of both ends of the base frame 32, holes 34 are widened so as to receive protrusions 36 of the auxiliary frame 33, and the main body (plate-shaped) of the one area is provided. (see FIG. 6(b)). It is designed to be

The rear surface of the pole 2 is formed with two holes (not shown) for receiving the two columnar projections 38 and a screw hole (not shown) for receiving a screw inserted into the hole 37 formed in the central portion. . The two holes for receiving the two columnar projections 38 are useful for positioning the magnet embedding member 31 .
Therefore, the auxiliary frame 33 can be connected to the pole 2 by screws inserted into the holes 37 with the surface opposite to the surface where the magnets 30 are exposed being in contact with the rear surface of the pole 2. A base frame 32 to which a frame 33 is coupled, that is, a magnet embedding member 31 is installed on the rear surface of the two poles 2 via an auxiliary frame 33 so that the surface where the magnet 30 is exposed can come into contact with the wall surface inside the car. be able to.

FIG. 9 shows a magnet embedding member 31 attached to the rear side of the poles 2 straddling two poles 2 erected along the wall surface inside the car. In this figure, since the length of the magnet-embedded member 31 is the same as the outer dimension of the space between the two poles 2, the auxiliary frames 33 at both ends, except for the plate-like projections 35, are attached to the back and base of the poles 2. It is hidden behind the both ends of the frame 32, and the front side of the base frame 32 (the side opposite to the side where the magnets are embedded) is visible.

Although only one magnet embedded member 31 is shown in FIG. 9, it is difficult to firmly install the pole 2 between the floor surface and the ceiling surface with only one magnet embedded member. It is desirable that the magnet-embedded member 31 be installed laterally between the two poles 2 of . Although it depends on the magnetic force of the magnet, if a commercially available magnet is used and the pole 2 has a height of about 2000 mm, three to five magnet embedding members 31 can be installed in the height direction to obtain two magnets. pole 2 can be firmly attached.
By providing a plurality of magnet embedding members 31 in this manner, the two poles 2 can be firmly fixed along the wall surface inside the car.

If the magnet-embedded member 31 is exposed, it may be peeled off, so a blindfold cover 39 is attached in FIG. In this figure, one magnet-embedded member 31 installed under the pole 2 is exposed for the sake of explanation, but all the multiple magnet-embedded members 31 attached to the pole 2 can be covered with a blindfold cover 39. is desirable.

The magnet embedded member 31 described above is installed between the two poles 2, but this is the only mechanism that uses magnets to install the two poles 2 along the wall surface inside the elevator car. not a thing
For example, instead of being installed between two poles 2, two poles 2 can be installed by attaching a magnet-embedded member to the back surface of the pole 2 for each single pole 2 of the two poles 2. 2 can be firmly fixed and installed between the ceiling 100 and the floor 200 along the wall surface inside the car. In this case as well, the magnet embedding members can be attached to a plurality of locations in the height direction on each of the two poles 2 .

With the lifting device of the present invention, the storage box 15 hooked on the lifting plate 11 can be held near the inner wall surface of the elevator car and near the ceiling. dead space can be reduced. In addition, since the storage box 15 can be lowered to easily take out the stored disaster goods, it is possible to respond quickly in an emergency.
