Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is arranged around a building to elastically catch falling objects falling from the top of the building, thereby minimizing damage to falling objects. related to buffer structures intended to limit

Recently, especially in shopping districts, buildings have become increasingly high-rise due to the rising cost of land and the efficient use of floor space.

In addition, the rooftops of such high-rise buildings are generally open to the public for various purposes, such as play facilities for children's play areas, passageways to the rooftops for parking, and other uses.

However, children are also easily absorbed in play and adventurous, and often engage in risky behavior.

Even adults can be exposed to danger due to unexpected things.

A protective fence of an appropriate height is usually installed around the rooftop, but children in particular can climb onto the fence using nearby items such as boxes, or climb over the fence to get excited about playing. Unfortunately, accidents such as falling from the roof to the ground also occur.

However, even if you fall from the roof, if an adjacent building happens to be under construction, you may come into contact with scaffolding, etc., so this will absorb the impact from the street and somehow save you. There is also.

However, since scaffolds are usually made of hard materials and have exposed protrusions in some places, they are not only unsatisfactory in terms of shock absorption, but can even be dangerous. In many cases, the result is simply that some parts of the project have been cancelled.

The purpose of the present invention is to provide a buffer structure that functions effectively even in the event of a fall accident, especially in such high-rise buildings. Since the influence is difficult to be felt, examples will be described below with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of a falling object buffering structure provided at the lower front of a building.

1 is a building, 2 is a protective fence stretched around the roof of the building at an appropriate height, and 3 is a sidewalk provided adjacent to the building 1.

Reference numeral 4 indicates a buffer structure for falling objects, which is designed to cover at least a part of the sidewalk 3 by a portion projecting from the front of the building 1.

5 is a net that directly catches falling objects and absorbs the impact; 6
Reference numeral denotes a frame for stretching the net 5 with a predetermined strength, 7 a support for supporting the frame 6, and 8 a support receiver for rotatably supporting the support 7.

2 and 3 show in detail the falling object buffering structure 4 shown in FIG. 1, and are sectional views when it is installed in the building 1. FIG.

Note that the same elements as those shown in FIG. 1 are given the same reference numerals.

9 is a column used in the building 1; 10 is a box embedded in and supported by the column 9; 11 is a spring fixed to the box 10; 12 is a wire to which the other end of the spring 11 is connected. .

13 and 14 are rollers, and 15 is a locking claw.

This will be described in more detail with reference to FIG.

The box body 10 to which one end of the spring 11 is fixed is attached to the support 9
Since the wire 12 is embedded and supported in a recess opened at a predetermined height, the wire 12 is guided by rollers 13 and 14.
The frame body 6 is connected to the other end of the spring 11 via the
It is locked to the utensil 1 so that it can come into contact with and separate from it.

Further, one end of the support body 7 is rotatably supported by a support receiver attached to a predetermined position of the support column 9, and the other end is rotatably supported on the other end side of the frame body 6. Keep it
The tension of the spring 11 is set to a predetermined strength, and the frame body 6 is usually
Make sure that it can withstand the weight including the

Since the frame 6 has the net 5 stretched over its entire surface with a predetermined strength, the interaction between the frame 6 and the net 5 results in an even stronger structure.

Note that the box 10 and the spring 11 constitute a first shock absorption mechanism, and the net 5, frame 6, and support 7 constitute a second shock absorption mechanism.
A shock absorption mechanism is constructed.

Here, in the event of an unfortunate fall accident, the buffer structure operates as follows.

That is, the falling object is first stopped by the net 5 stretched over the frame body 6, and most of the energy of the fall is absorbed by the impact-absorbing action of the net. Since the remaining energy is also absorbed by the action, the strength of the impact received by the falling object is reduced to a sufficient extent to withstand it.

However, since the energy of the falling object is quite strong, the falling object may bounce back, but in that case, the net 5 and spring 11 return to their original states, and the net 5 then stops the object. Since the energy of the falling object is much less than before, the strength of the impact on the falling object is greatly reduced each time.

In this way, falling accidents can be avoided by the buffer structure.

FIG. 3 shows another embodiment of the present invention, in which the buffer structure shown in FIG. 2 has a structure in which the frame body 6 on which the net 5 is stretched is stacked in two stages. First stage frame 6 shown
The other end of the second-stage frame 6 is rotatably supported on the other end, and one end of the second-stage frame 6 is connected to a locking claw 15 from one end of the first-stage frame 6. It is removably locked using a lock.

With such a structure, the falling energy of the falling object is effectively absorbed by the upper and lower two-tier nets.

Furthermore, when the locking pawl 15 is operated to release the second frame 6, this frame 6 will be suspended from the other end side of the first frame 6. It is also possible to descend to the sidewalk 3 through a net 5 set up in the area.

Note that the first shock absorption mechanism is not limited to one that uses a spring, but may also be one that uses gas or the like, and the second shock absorption mechanism may also be one that uses a sponge outside the mesh. Supports may also be provided separately rather than being part of the building.

As described above, according to the present invention, effects such as being able to sufficiently absorb the energy of a falling object and quickly evacuate can be obtained with an extremely simple configuration.

Further, according to the present invention, since the falling object is stopped midway, a collision can be avoided even if the falling object is walking directly below it.
