Description

[Detailed Description of the Invention] The present invention is arranged around a building and elastically catches falling objects falling from the top of the building, thereby minimizing damage to the falling objects. Regarding the buffer structure that is trying to stop it.

Recently, especially in shopping districts, buildings have become increasingly high-rise due to the rising cost of land and the need to use floor space more efficiently. In addition, in such high-rise buildings, the rooftops are generally open to customers, and are used for various purposes, such as creating play facilities for children's play areas, or creating parking spaces by creating rooftop walkways. However, children are also easily absorbed in play and adventurous, often engaging 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 are eager to play by climbing onto the fence using nearby boxes or other objects. Unfortunately, accidents such as falling from the rooftop 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 and fall.
This may help absorb the impact of the fall and save your life. However, since scaffolds are usually made of hard materials and have exposed projections in some places, they are not only unsatisfactory in terms of shock absorption, but can even be dangerous. , the result is often nothing more than a survival effort.

Now, 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.
It can be easily installed and is not easily affected by wind and rain.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 structure for cushioning falling objects, and the structure extends from the front of the building 1 to cover at least a portion of the sidewalk 3. 5 is a net that directly receives a falling object and absorbs its impact; 6 is a frame that stretches the net 5 with a predetermined strength; 7 is a support that supports the frame 6; and 8 is a support that rotates the support 7. It is a support holder that can be freely pivoted. 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. In addition, the first
Elements that are the same as those shown in the figures 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 embedded and supported in a recess made at a predetermined height in the support column 9, so that the spring 11 is supported by the wire 12 guided by the rollers 13 and 14. The frame body 6 connected to the other end is latched to the building 1 so as to be able to come into contact with and separate from it. In addition, the support body 7 is a column 9
One end is rotatably supported by a support receiver attached to a predetermined location, and the other end is rotatably supported on the other end side of the frame 6, so that the tension of the spring 11 is It is made to have a predetermined strength and is usually made to withstand the weight including the frame body 6. Frame body 6
Since the net 5 is stretched over the 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, the frame 6, and the support 7 constitute a second shock absorption mechanism.

FIG. 3 shows the buffer structure shown in FIG. 2, which has a structure in which the frame bodies 6 on which the nets 5 are stretched are stacked in two stages, and in addition to the frame bodies 6 in the first stage shown in FIG. The other end of the second stage frame 6 is rotatably supported on the end side, and one end of the second stage frame 6 is connected to the first stage frame 6.
It is removably locked from one end using a locking pawl 15.

Here, in the event of an unfortunate fall accident, the buffer structure operates as follows. That is, the falling object is first caught by the net 5 stretched over the frame 6, and most of the energy of the fall is absorbed by the net's large impact absorption effect, but the spring 11
Since the remaining energy is also absorbed by the impact-absorbing effect of , the strength of the impact received by the falling object is reduced to a sufficient extent to withstand it. However, since the energy of a 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 falling object is then caught by the net 5. Since the energy of a falling body becomes less and less than before, the strength of the impact received by a falling body decreases greatly each time. In this way, falling accidents can be avoided by the buffer structure.

With the two-tiered structure, falling objects are caught by the nets 5 stretched between the first and second frames 6, and the falling energy of the falling objects is effectively absorbed by the upper and lower two-tiered nets. will be absorbed into. 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 net. Supports may also be provided separately rather than being part of the building.

As described above, according to the present invention, since the second impact absorption mechanism has a two-stage structure, effects such as being able to sufficiently absorb the energy of a falling object and quickly evacuate can be obtained. Further, according to the present invention, since the falling object is caught on its way, it is possible to avoid a collision even if the object is walking directly below it.
