The present invention relates to a retractable evacuation pipe that can be extended to.

[0002]

2. Description of the Related Art In modern buildings, many kinds of various chemical products are used. Therefore, once a fire occurs, it quickly goes around, and moreover, it produces toxic gas. for that reason,
It is necessary for human beings to escape as soon as possible, but when an evacuation tool such as a conventional evacuation ladder is used to escape, it takes time to prepare and may be covered with smoke. In addition, in the buildings on the second and third floors, such evacuation equipment is often not prepared, and people may jump from the window and be injured. Therefore, in any case, if there is a fire in the middle and upper floors, there is often a risk of life, and there has been a demand for evacuation equipment that can be quickly prepared and can be easily escaped.

[0003]

SUMMARY OF THE INVENTION The present invention addresses such a situation and is usually short, for example, mounted on the wall of the second floor of a building so that it does not get in the way. The purpose of the present invention is to provide a retractable evacuation pipe that extends to the ground and to meet the above demand.

[0004]

[Means for Solving the Problems] That is, the present invention, which is adapted to the above-mentioned object, provides a mounting plate to be mounted on a wall surface of a house, a supporting plate protruding from the mounting plate, and a lower surface of the supporting plate, which is connected via a ball joint. From the stretchable pipe part
It is characterized by constructing an evacuation pipe.

In this case, the expandable pipe portion is composed of a plurality of small pipes having different diameters, and the upper end of the small pipe having the smallest diameter is connected to the ball joint and the small pipe having the largest diameter is connected to the small pipe. Is provided with a hook-shaped locking groove downward from the upper opening end thereof, a blind plate is provided at the lower end opening thereof, and further, at the required lower end portion and required upper end portion of each small pipe, each intermediate A large-diameter portion having a large diameter and a small-diameter portion having a small diameter are formed as compared with the portion. A pin is provided on the side of the ball joint. When another small pipe is loosely fitted around the smallest diameter small pipe to shorten the pipe portion, the pin can be fitted into the groove of the largest diameter small pipe to maintain the shortened state. When the pin is removed from the groove, the inner circumference of the upper small diameter portion of the larger diameter small pipe is fitted to the outer circumference of the lower large diameter portion of each small pipe, and the pipe portion extends downward. Configured as possible.

[0006]

According to the present invention, when the pin is removed from the groove, the small pipes other than the smallest diameter pipe are lowered by their own weight, and the larger diameter small pipe is placed on the outer circumference of the lower large diameter portion of each small pipe. The inner periphery of the small diameter portion of the upper end of the pipe is fitted from above, and the entire pipe portion extends to a constant length. The speed of extension is substantially the speed at which each small pipe falls, and is extremely rapid. Moreover, the pipe portion when extended has a very stable form in which a small pipe having the smallest diameter is located at the upper end and the diameter gradually increases as it goes downward.

Therefore, a person can escape from the fire extremely quickly along the pipe section. Also,
The upper end of the pipe is attached to the locking member via a ball joint, so if the area directly below the pipe is dangerous, you can change the direction of the pipe and securely escape to a safer place. .

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a side view of an evacuation pipe according to the present invention. In the figure, reference numeral 1 is a pipe portion, and 2 and 3 are a mounting plate and a support plate for supporting the pipe portion 1.

In this case, the pipe portion 1 is composed of three small pipes 4, 5, 6 having different diameters on the assumption that the pipe portion 1 is attached to the wall surface on the second floor. Each small pipe 4, 5, 6
Are loosely fit to each other, and a small pipe 4 having the smallest diameter, a small pipe 5 having the next largest diameter, and a small pipe 6 having the largest diameter are vertically arranged in this order to be in an extended state, and the small pipe 4 having the smallest diameter is surrounded. The other small pipes 5 and 6 are loosely fitted in and are in a shortened state. The small pipes 4, 5, 6 are preferably made of stainless steel, but may be made of iron, aluminum, or another metal.

Of the three small pipes 4, 5, 6
Although the two pipes have substantially the same length, only the small pipe 6 having the maximum diameter needs to include the other small pipes 4 and 5 at the time of shortening, and is slightly long. Then, at the time of extension, the entire length of the pipe portion 1 extends to a specified length (in this case, about 450 cm), and the lower end comes into contact with the ground.

Further, FIGS. 2, 3 and 4 are cross-sectional views of the small pipes 4, 5 and 6. The connecting mechanism of the small pipes 4 to 6 at the time of extension will be described with reference to these sectional views. In the small-diameter pipe 4 shown in FIG. 2, a large-diameter portion 7 is formed at the lower end thereof so as to bulge slightly outwards from the others.
On the other hand, in the small pipe 5 having the second largest diameter shown in FIG. 3, a small diameter portion 8 contracted inward is provided at the upper end portion, and a large diameter portion 7 bulging outward is provided at the lower end portion. Further, in the small-diameter pipe 6 having the maximum diameter shown in FIG. 4, the small-diameter portion 8 is arranged at the upper end portion. Such small pipes 4-6
The large-diameter portion 7 and the small-diameter portion 8 are formed over a predetermined length of, for example, about 15 mm from the ends, and when the pipe portion 1 is extended, the large-diameter portions 7 and 7 of the small pipes 4 and 5 are formed. On the other hand, the small-diameter portions 8, 8 of the small pipes 5, 6 having a larger diameter are fitted from above to prevent mutual separation and define the length when extended.

Further, in particular, a small pipe 4 having a minimum diameter shown in FIG.
Screw holes 10 and 10 for mounting a ball joint 9 which will be described later are opened at required positions on the upper part of the above, while a hook-shaped locking groove 11 is provided on the upper part of the small pipe 6 having the maximum diameter shown in FIG.
Are opened downward from the upper opening end and in a direction parallel to the opening end. Furthermore, the bottom end opening of the small-diameter pipe 6 having the maximum diameter is closed by screwing a flap 12 made of synthetic resin. These actions will be described later.

Next, the mounting plate 2 and the supporting plate 3 for supporting the pipe portion 1 will be described with reference to FIG. 5. The mounting plate 2 is mounted on a wall of a building or the like.
Bolt holes 13, 13 and 13 are provided at three places in the upper, middle and lower parts and are securely fixed to the building wall surface by bolts.

On the other hand, the support plate 3 is a steel material that horizontally projects from the mounting plate 2, one end of which is welded to the mounting plate 2 and the lower surface of which is supported by the support member 14.

However, the lower surface of the tip of the support plate 3 is shown in FIG.
As shown in, a ball joint 9 is attached. The ball joint 9 is a well-known one having an upper engaging portion 15 and a lower movable portion 15 ', and the supporting plate 3
The locking portion 15 is attached to the bolt 1 via the washer 16.
It is concluded by 7.

Then, as shown in FIG. 7, the upper end portion of the small pipe 4 having the minimum diameter is screwed to the other end of the ball joint 9 and the movable portion 15 '. As a result, the tip of the pipe portion 1 can be raised about the ball joint 9 to a substantially horizontal direction and can be rotated about 180 degrees.

A locking pin 18 is provided on the side of the locking portion 15 (see FIG. 6).
Reference numeral 8 denotes a pin which can be fitted into the locking groove 11, and when the pipe portion 1 is shortened, the pin 8 is fitted to the deepest portion of the locking groove 11 as shown in FIG. And the pipe portion 1 shortened state is maintained.

In the case of the present invention, since the pipe portion 1 is installed outdoors in a shortened state, invasion of rainwater or the like into the pipe portion 1 is unavoidable, and the maximum diameter of the lower surface of the support plate 3 cannot be avoided. A packing (not shown) is attached to the contact portion of the small pipe 6.

Next, the method of using the evacuation pipe of the present invention constructed as described above will be explained. First, as shown in FIG. 8, the mounting plate 2 is attached to the wall near the window on the second floor of the building, for example. Attach to.

Usually, as described above, the pipe portion 1
Will be shortened. In order to shorten the pipe part 1, all that is necessary is to raise the pipe 6 having the maximum diameter by hand, so that the lower end of the small pipe 5 comes into contact with the blind plate 12 at the lower end of the pipe 6 having the maximum diameter, and the pipe 6 is raised together. , The smallest small pipe 4
The other small pipes 5 and 6 are loosely fitted around and the shortened state shown in FIG. 7 is obtained. In order to hold this, the pin 18 is fitted into the locking groove 11 immediately before the uppermost end of the small diameter pipe 6 having the maximum diameter reaches the lower surface of the support plate 3. At that time, while raising the small pipe 6, the pin 18
Is inserted into the locking groove 11, and when the pin 18 reaches the lowermost portion of the groove 11, the small pipe 6 having the maximum diameter is rotated clockwise. As a result, the pin 18 is fitted to the innermost portion 11 ′ of the locking groove 11, and the small pipes 5 and 6 are prevented from falling.

Then, in case of fire, the small-diameter pipe 6 having the maximum diameter is rotated in the opposite direction to the above. By this operation, the pin 18 is positioned in the vertical groove portion of the locking groove 11, and at that moment, the small pipe 5 of the second diameter and the small pipe 6 of the maximum diameter are separated from the small pipe 4 having the smallest diameter. It falls by its own weight, and as described above, the respective end portions engage with each other at the large diameter portion 7 and the small diameter portion 8 and extend to a predetermined length.

Evacuation from the second floor is carried out along the pipe portion 1 thus extended. Since the pipe part 1 becomes thicker as it goes downward, it is stable and can escape very quickly. Further, since the pipe portion 1 is attached to the support plate 3 via the ball joint 9, the extended pipe portion 1
It is also easy to move the tip of the to the other direction from the vertical direction. For example, if the ground under the pipe section 1 is already dangerous,
The pipe part 1 can be passed over to another building or the like to escape to a safer place.

The embodiment of the present invention has been described above. Needless to say, the number of small pipes 4, 5 and 6 in the above description can be appropriately changed according to the place of installation, height and the like. Is. Although the mounting plate 2 is mounted on the wall surface of the building, it is also preferable to mount the mounting plate 2 on the handrail of the terrace 19 when the terrace 19 is overhanging as shown in FIG. 9, and in other cases. It can be changed as appropriate.

[0024]

As described above, the present invention is an evacuation pipe constructed by a plurality of small pipes that can be expanded and contracted, and when evacuation occurs in a fire or the like, the small pipe with the maximum outer diameter is slightly rotated. Just by doing, the pin will come off from the locking groove,
Since the pipe extends downward momentarily, it does not take time to prepare for it, and it has the effect of being able to escape from the middle and high floors extremely quickly and reliably.

Moreover, since the uppermost small pipe is attached to the support plate by a ball joint, it is easy to change the direction of the pipe, and the tip of the pipe should be attached even when it is dangerous to escape directly below. You can safely escape by hanging it over other places.

Further, as described above, in addition to being extremely effective in the event of a fire or the like, since it is normally held in a shortened state on the walls of the middle and high floors, it does not become an obstacle at all.
It also has the advantage of not being stolen.
