Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telescoping tower, and more particularly to a telescoping tower suitable for use as an escape or fire extinguisher in the event of a fire occurring in a high-rise building.

0002

BACKGROUND OF THE INVENTION In recent years, buildings have become taller and taller, and in response to this, emergency escape devices have become necessary in case a fire breaks out in a high-rise building. Conventionally, as an escape device from a high-rise building, a vehicle equipped with a retractable ladder has been used.

0003

[Problems to be Solved by the Invention] By the way, it is extremely difficult to lengthen the telescoping stroke of a telescoping ladder due to its structure, and it cannot be adequately used for emergency evacuation of high-rise buildings. There is a sense of fear in escaping through communication, and there is a problem in that escape activities cannot be carried out smoothly.

[0004] Therefore, the present invention provides a telescoping tower that can obtain a long telescoping stroke, can be reliably used for emergency evacuation of high-rise buildings, and can also be used for safe evacuation without fear. The challenge is to provide this.

[0005]

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides a structure in which a plurality of telescopic bodies formed by sequentially connecting cross links vertically are assembled and separated on a rotatable platform. A cylinder is arranged in a frame shape so that the recoil can be freely moved, and a cylinder is arranged at the center of the telescoping bodies on the table, and is connected to the upper part of each telescoping body to make each telescoping body extend and retract. At the outside position, a corresponding telescopic body is formed by combining a large number of single pillars so that they can be freely expanded and contracted up and down, and a pillar that is formed by combining them so that they can be freely inserted and removed up and down in synchronization with the expansion and contraction of the telescopic body. The pillars are arranged in a state where they are connected to each other, and the pillars are formed so that the pillars are separated for each cross link and can be inserted and removed by the expansion and contraction of the expandable body.

[0006]

[Operation] When the cylinder is contracted, each telescopic body is folded, and the column itself is folded, when the cylinder is extended,
Each expandable body expands to form a frame shape, and on the outside of the four corners of each expandable body, single columns are vertically arranged in series. When the expandable body is slightly contracted, the upper and lower columns become connected to form a column, and this column expands and contracts. The body is fixed in an extended state and is stable, and the inside of the extended stretchable body can be used as a passageway for evacuation.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples of the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, a platform 4 is installed on the loading platform 2 of an automobile 1, and is rotated and raised by a drive mechanism 3. On this platform 4, extendable bodies 5 are arranged in a frame shape on all sides. A multi-stage cylinder 6 for expanding and contracting the expandable body 5 is installed in the center of the area surrounded by the expandable body 5, and struts 9 are placed outside at the four corners of the group of contractible bodies 5. Tower 7 is formed.

[0009] The above-mentioned telescopic body 5 has a large number of cross links 8 in which two links are pivotally connected to each other at the center, and the ends of the links are pivotally connected to each other to sequentially connect the upper and lower parts. It is designed to be expandable and contractible.

[0010] Since the width of the elastic body 5 changes when it is contracted and expanded, the lower ends of both sides of each elastic body 5 are connected to guides 10 provided on the table 4, as shown in FIGS. 4 and 7. It is supported on a movable base 11 that moves along the stretchable body 11, and is freely movable in the inward and outward directions by extension and contraction, and the conditions of the adjacent side edges of each extendable body 5 are kept constant in both cases of contraction and extension. There is.

As shown in FIGS. 8 and 9, the adjacent telescopic bodies 5 are connected to each other at the end pivot points of each cross link 8 via pivot pins 13 with L-shaped connecting fittings 12. The four-sided extensible body 5 is connected in a frame shape by this connecting fitting 12.

The upper end of the cylinder 6 is connected to an upper plate 14 attached to the upper end of the extensible body 5 under the same conditions as the stand 4, and the expansion and contraction of the cylinder 6 causes all the extensible bodies 5 to expand and contract at the same time. Note that a tension spring may be provided between the end pivot points of the cross link 8 so that the elastic body 5 can be smoothly contracted.

As shown in FIG. 7, on the inner periphery of each stretchable body 5, a staircase 15 and a handrail 16 are arranged in a spiral manner along the inner surface of the link, and are surrounded by the stretchable body 5. The square tube-shaped interior can be used as an evacuation passage.

Furthermore, an elevator 41 is built into the interior surrounded by each expandable body 5 so as to move up and down by utilizing the space formed between the cylinder 6 and the stairs 15.

This elevator 41 is formed into a box shape with a cylinder 6 passing through the center, and is moved up and down inside a group of 5 elongated telescopic bodies by a hoist 42 installed on the upper plate 14, and a large number of It is now possible to evacuate people at the same time.

As shown in FIG. 8, the pillar 9 is formed by connecting a large number of single pillars 9a using pipes so that they can be moved up and down, and stands upright on a movable base 11. It is combined with the stretchable body 5 and can freely move inward and outward directions together with the stretchable body 5 when the stretchable body 5 is expanded or contracted.

The single column 9a has a length slightly longer than the distance between the upper and lower ends of the cross link 8 of the extended telescopic body 5, and its upper end is connected to the connecting fitting 12 as shown in FIGS. 8 and 9. It is pivoted on the outer surface of the lower column 9a by a pivot 21, and can swing freely in the surface direction of the corresponding telescopic body 5 about the pivot 21, and its lower end can be freely inserted and removed from the upper end of the lower column unit 9a. It is formed with a small diameter connection 9b that fits into the .

This column unit 9a is attached to each connection fitting 12 located above and below, and a cylinder 22 is attached between the midway of each column unit 9a and the central pivot portion of the cross link 8 in the corresponding telescopic body 5. A telescopic motor is provided so that each column 9a can be tilted inward from a vertical position.

By inclining each column 9a inward, the expandable body 5 can be contracted as shown in FIG. 6, and the columns 9a are stacked one above the other.

[0020] Also, by extending the telescopic body 5, the cylinder 22
When each column 9a is made vertical, the upper and lower columns 9a are coaxially arranged in series, and when the expandable body 5 is slightly contracted in this state, the connecting portion 9b at the lower end becomes the lower column as shown in FIG. It fits into the upper end of the single body 9a, and the whole becomes a single support 9, reinforcing the extended state of the 5 group of expandable bodies at the four corners.

The lower end of the lowest pillar unit 9a is adapted to fit in and out of a protrusion 23 provided on the movable base 11, as shown in FIG.

[0022] When extending a long tower in which a plurality of telescopic body groups are connected vertically using a single multi-stage cylinder, the upper telescopic body group is installed on the upper plate of the lower telescopic body group, and the lower telescopic body is The lower end of the extended multi-stage cylinder is released from the stand and contracted upward, the lower end is fixed at an appropriate position of the lower telescopic body group in the raised position, and the multi-stage cylinder is extended again to extend the upper telescopic body. Bye.

Furthermore, in order to stabilize the relationship between the extended tower and the building A and improve stability during escape, the clamp 31 and transition section 32 of the building A are attached to the top of the upper plate 14, as shown in FIG. A clamp for the window and a transition part 33 are also provided in the middle of the tower. The above-mentioned crossing section 32 and 3
3, a blower 48 and an exhaust fan are installed as shown in FIG. 2 to eliminate smoke from the windows in the event of a fire and to allow evacuation to be carried out without any trouble. A water sprinkling function is added to the above-mentioned clamps, and the wire connecting the tower 7 and the pillars in the room is also made hollow so that water can be sprayed. Furthermore, although not shown,
A crane for construction work can also be installed on the top plate 14.

[0024] Furthermore, the automobile 1 on which the tower is mounted is shown in FIG.
As shown in Figure 3, there is an endless band 5 on the chassis part.
1, remove it and install the front and rear wheels 52, 5.
At the same time, the front wheel 53 is wrapped around the outer circumference of the large diameter tire 53.
By replacing it with a, it is possible to smoothly go up and down slopes such as stairs.

The telescoping tower of the present invention has the above-mentioned structure, and when the automobile 1 is running, the cylinder 6 is contracted to contract the tower and the tower is placed on the vehicle body 2, as shown by the two-dot chain line in FIG. It can be placed horizontally, which reduces the overall height and allows for smooth driving.

Next, in the event of an emergency such as a fire, the platform 4 is laid down on the loading platform 2 and the tower 7 is raised, as shown by the solid line in FIG. If we extend the column 9a vertically using the cylinder 22 and slightly contract the expandable body 5, we will create a tower 7 whose four corners are reinforced with supports 9, and as shown in Figure 2, the extended tower 7 will become a building A. If it is fixed, an escape passage with a spiral staircase will be formed within the tower 7, allowing escape from the building A and firefighting operations to be carried out safely and efficiently.

When the extensible body 5 is extended, the single column 9
The columns a are sequentially connected vertically to form a single support 9, which reinforces the four corners of the tower 7 and improves the overall rigidity, ensuring safety even when a large number of people are on it.

The tower 7 can be contracted by performing the opposite operation to the above-mentioned extension, and by tilting the individual columns 9a inward as shown in FIG. 6, the towers 7 are stacked vertically to be in a stored state.

[0029]

[Effects] As described above, according to the present invention, telescoping bodies in which crosslinks are sequentially connected vertically are arranged in a frame shape, and the telescoping bodies are made to extend and contract with cylinders, and supports are placed at the four corners of each telescoping body. However, since the extended telescopic body is reinforced with supports, an evacuation passage can be secured inside the tower by extending the telescopic body, and the extended state of the telescopic body is maintained by the support pillars. This greatly improves rigidity, allowing for safe evacuation and firefighting in emergencies.

[0030] Furthermore, since the crosslinks of the expandable body are sequentially connected in the upper and lower directions, the expansion/contraction rate is large and a long extended state can be obtained, so that it can be effectively used for evacuation of high-rise buildings.
