Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 and 5, a table 4 to which turning by a driving mechanism 3 and undulating movement by a cylinder 3a are provided on a bed 2 of an automobile 1, and is vertically expandable and contractible on the table 4. A stretchable body 5 is attached to each of the stretchable bodies 5 so as to form a frame-like arrangement, and a cylinder 6 for extending and contracting the stretchable body 5 and holding the stretched state is provided at the upper and lower ends and intermediate portions of each stretchable body 5. A tower 7 is formed by providing an expansion / contraction drive device using jacks, jacks, or the like, and arranging columns 9 at the four corners of the group of elastic bodies 5 and outside the sides of the adjacent elastic bodies 5. In addition,
The elastic bodies 5 may be arranged not only in four directions but also in polygons such as five directions and six directions.

The telescopic body 5 uses a number of cross links 8 in which two links are pivotally connected to each other at a central portion, and the link ends of the vertically arranged cross links 8 are pivotally connected to each other. Thus, the pantograph mechanism is connected to the upper and lower parts sequentially and can be vertically expanded and contracted. The cylinder 6 for expanding and contracting the elastic body 5 draws or pushes both ends of the cross link 8.

Since the width of the elastic body 5 changes between contraction and expansion, the lower ends of both ends of the lowest link of each elastic body 5 are provided on the base 4 as shown in FIGS. Is supported on a movable base 11 that moves along a guide 10 which is movable along the guide 10, and is movable inward and outward by expansion and contraction, so that in each case of contraction and extension, the spacing condition between adjacent side edges is constant. It is supposed to.

As shown in the figure, each of the adjacent elastic members 5 has an L-shaped connection fitting 1 at the end pivot point of each of the upper and lower cross links 8.
The two elastic members 5 are connected to each other via a pivot pin 13 and the connecting fittings 12 are connected to the four elastic members 5 in a frame shape.

A tension spring may be stretched between the end pivot points located on both sides of the cross link 8 or the movable table 11 may be forcibly moved by a cylinder so that the contraction of the movable member 11 can be performed smoothly.

As shown in FIGS. 3 and 4, a stair 15 which is arranged in a spiral state along the inner surface of the link, and a handrail as required, are arranged on the inner periphery of each of the telescopic members 5 as shown in FIGS. 7
The inner space of a rectangular tube surrounded by the elastic body 5 can be used as an evacuation passage.

An elevator 41 is incorporated in each telescopic body 5 so as to move up and down by utilizing a space surrounded by the steps 15. The elevator 41 has a telescopic body 5
A hoisting machine is installed on the upper plate 14 attached to the upper end of the group under the same conditions as the platform 4, and the hoisting machine makes it possible to move up and down inside the elongated tower 7 to evacuate many people at the same time. I can do it.

As shown in FIG. 6, the column 9 is formed by connecting a large number of column members 9a using pipes so that they can be freely pulled up and down. The elastic members 5 are combined with the elastic members 5 on both sides, so that the elastic members 5 can move inward and outward integrally with the elastic members 5 when the elastic members 5 expand and contract.

The column unit 9a has a length slightly longer than the interval between the upper and lower ends of the link in one of the cross links 8 of the elastic body 5 extended to a predetermined length. As shown in FIG. 7, a pivot 21 pivots on the outer surface of the connection fitting 12, and the extensible member 5 located on both sides around the pivot 21 is swingable in the surface direction outside one of the extensible members. The portion is formed with a small-diameter connection shaft 9b which is detachably fitted to the lower end portion of the upper column unit 9a. The small-diameter connection shaft 9b and the lower end of the upper column unit 9a are tapered to prevent rattling.

The pillar unit 9a has a connection fitting 12 at its upper end.
And a cylinder or a telescopic motor is provided between the middle of each column unit 9a and the central pivot of the cross link 8 in the corresponding telescopic body 5 to move each column unit 9a inward from the vertical state. May be made to be inclined.

By inclining the pillars 9a inward, the telescoping body 5 can be contracted as shown in FIG. 5, and the pillars 9a are folded up and down.

When each of the pillars 9a is vertically extended by its own weight by slightly extending the elastic body 5 from the predetermined length, each of the upper and lower pillars 9a is arranged in a coaxial series connection in this state. When it is slightly contracted to a predetermined length, the connecting portion 9b at the lower end is fitted to the upper end of the lower column unit 9a as shown in FIG. At the four corners. In order to accurately arrange the individual pillars 9a in series, the lower portions of the upper and lower individual pillars 9a are sequentially connected by wires 31 as shown in FIG.

As shown in FIG. 3, the lower end of the lowermost column unit 9a is detachably fitted to a projection 23 provided on the movable base 11.

It is also possible to form a long tower in which a plurality of telescopic body groups are vertically connected, as shown in FIG.
The upper elastic body 5a group may be installed on the upper surface 4 under the same conditions as the lower elastic body 5 group. In this case, the crosslinks 8 of the upper elastic body 5a group may be made of a material such as aluminum for weight reduction. These crosslinks 8 may be configured such that the ends thereof can be freely extended and retracted by a cylinder, and the width of the elastic body 5 when contracted is reduced, so that the conditions for placing the crosslinks 8 on an automobile are advantageous.

Further, in order to stabilize the relationship between the extended tower and the building A and to improve the stability of the tower upon escape,
As shown in FIG. 10, a clamp 31 and a transition portion 32 of the building A are provided on the upper part of the upper plate 14, and a clamp and a transition portion 33 for windows on each floor are provided in the middle of the tower. In the crossover sections 32 and 33, as shown in FIG.
8 and an exhaust fan have been installed to eliminate smoke from windows in the event of a fire so that evacuation can be performed without difficulty. A watering function is added to the clamp and the like, and a wire connecting the tower 7 and a pillar in the room is made hollow so that water can be discharged. Further, although not shown, a crane for construction work can be installed on the upper plate 14.

An automobile 1 equipped with a tower is shown in FIG.
As shown in FIG. 1, an endless belt 51 is attached to a chassis portion, removed and wound around the outer periphery of the front and rear rear wheels 52, 52, and the front wheel 53 is replaced with a large-diameter tire 53a. And the like can be smoothly raised and lowered.

The telescopic tower of the present invention has the above-described structure. When the automobile 1 is running, the tower is contracted by contracting the cylinder 6 as shown by a dashed line in FIG. As a result, the overall height is reduced, and traveling can be performed without any trouble.

Next, in the event of an emergency such as a fire or the like, as shown by the solid line in FIG. 1, the platform 4 falls down on the carrier 2 to raise the contracted tower 7, and in this state the cylinders 6 and 16 are extended. When the telescopic body 5 is extended and the respective pillars 9a are vertically extended by the cylinder or the wire 61 and the telescopic body 5 is slightly contracted, the tower 7 whose four corners are reinforced by the columns 9 is formed.
If the tower 7 extended as shown in FIG. 10 is fixed to the building A, an escape passage in which a spiral staircase is arranged is formed in the tower 7, and escape and fire extinguishing work from each floor of the building A can be performed safely. It can be done efficiently. Also, if the building is tall, two cars will be dispatched and one tower will be lifted by helicopter,
It can be extended on the other tower to form a long tower.

When the elastic body 5 is extended, the column 9
a is sequentially joined up and down to form a single support 9, and the support 9 reinforces the four corners of the tower 7 and improves the overall rigidity, so that safety can be ensured even when a large number of people are loaded.

The contraction of the tower 7 can be performed by the reverse operation of the above-described extension, and each column 9a is inclined inward as shown in FIG.

Further, the tower 7 can be used for a purpose such as lifting a car to the rooftop or the like, as a machine for lifting objects.
