DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shock absorbing aid for a human body for protecting a human body when it falls down from a work place at a high place such as a construction site.

[0002]

2. Description of the Related Art In recent years, falling accidents at construction sites and the like have increased, and safety at labor sites has become a problem.
Therefore, as a shock absorbing aid for the human body that absorbs a drop impact when falling, an air bag is provided at a predetermined portion of the mounted body to be mounted on the human body, and when a sensor detects that both feet of the wearer have left the scaffold, An air bag has been developed in which the air bag is instantly inflated so that the air bag absorbs a drop impact on a human body (for example, Japanese Patent No. 2763510).

[0003]

In the above-mentioned shock absorbing aid for human body, both legs of the wearer do not leave the platform at the same time during standing and normal walking. There is a problem that both feet may separate from the scaffold, and it is necessary to prevent malfunction in such a case.

Further, as a so-called charging device for inflating an air bag, for example, as described in Japanese Patent Publication No. 58-14360, a cylinder filled with compressed gas and a firing pin facing one end of the cylinder are known. And an explosive that arbitrarily explodes when an electric current is applied, and the explosion of the explosive causes the firing needle to pierce one end of the cylinder to open the cylinder and eject gas from the cylinder into an air bag. Have been. In such a cylinder opening structure using a firing pin, when the firing pin pierces the cylinder, the pressure in the cylinder returns the firing pin to its original position, and gas is blown out from the perforation of the cylinder by the firing pin. In addition, a time loss may occur due to the reciprocating movement of the firing pin from the explosion to the opening of the cylinder, and in some cases, an unsealing failure may occur such that the firing pin rarely sticks out of the cylinder and does not come out and gas does not spout instantaneously. However, in the above-described human body shock absorption aid, it is necessary to inflate the air bag before the wearer falls, so that a charging device capable of always instantaneously ejecting gas is required.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object of the present invention is to provide a shock absorbing aid for a human body capable of reliably preventing malfunction and improving reliability.

The first air bladder 11 is provided at a site corresponding to the periphery of the neck of the human body, and is formed so as to cover both sides and the back of the neck. The second air bladder 12 is provided at a portion corresponding to the back of the human body, and is formed vertically long along the center of the back. In this case, the upper and lower ends of the second air bladder 12 are the first and third air bladders 11, 13 respectively.
Respectively. The third air bladder 13 is provided at a position corresponding to the circumference of the waist of the human body, and is formed so as to cover both sides and the back of the waist. Further, a charging device 20 is connected to the third air bag 13, and an inner peripheral surface corresponding to the connection portion is covered with a protective member 13 a made of a material having a buffer property such as cloth, rubber or plastic. .

The charging device 20 includes a cylinder 21 as a fluid-filled container filled with a compressed fluid, a gas discharge member 22 that covers one end of the cylinder 21, and an explosive 2 that opens the cylinder 21.

The cylinder 21 is formed of a metal container in which a compressed fluid is filled in a gas or liquid state, and one end thereof is closed by a sealing portion 21 a which can be opened by the explosion of the explosive 23. The sealing portion 21a is provided integrally with the cylinder main body, and is formed thinner than the cylinder main body side. As an example of the embodiment, the capacity of the cylinder 21 is 100 cc and the opening diameter thereof is 8
mm, the thickness of the sealing portion 21a is 0.4 mm, and a mixture of carbon dioxide and 25% of nitrogen gas is used as the compressed fluid.

When a current flows through 4, the explosive 23 explodes, and the pressure causes the sealing portion 21a of the cylinder 21 to be crushed as shown in FIG. 6A, and one end of the cylinder 21 is opened. As a result, as shown in FIG. 6 (b), the gas in the cylinder 21 blows out from the opening formed by the blast into the space 22a of the gas discharge member 22, and the gas discharge port 22 of the gas discharge member 22.
b is introduced into the third air bag 13. in this case,
Since the explosive 23 is accommodated in the cylindrical portion 22c that opens toward the sealing portion 21a of the cylinder 21, the pressure of the explosion is concentrated on the sealing portion 21a of the cylinder 21 and the explosive 23
Explosion, the sealing portion 21a of the cylinder 21 can be reliably opened. Further, when the fluid in the cylinder 21 is sealed in a liquid state, the fluid in the cylinder 21 is more instantaneously ejected due to a so-called bumping phenomenon in which the liquid is rapidly vaporized by the heat of the explosion.

And a sensor body 43 that accommodates the elastic member 41. A sphere 42 is attached to one end of the elastic member 41, and the other end is fixed to one end of the sensor body 43. A space 43a for accommodating the sphere 42 and the elastic member 41 is provided in the sensor main body 43, and the inner shape of the space 43a is formed slightly larger than the outer shape of the sphere 42 and the elastic member 41. An electrode 44 as a first conductor is provided on the surface of the sphere 42, and an electrode 45 as a second conductor is provided on the surface of the spherical portion of the space 43a.
Reference numeral 45 is connected to a circuit on the control unit 50 side. That is, in the acceleration sensor 40, as shown in FIG. 9, the elastic member 41 bends due to the gravity acting on the sphere 42, and the electrode 44 on the sphere 42 and the electrode 45 on the sensor body 43 are in contact with each other. When the acceleration acting on the sphere 42 becomes smaller than the gravitational acceleration (1 G), the electrode 44 on the sphere 42 is separated from the electrode 45 on the sensor body 43 as shown in FIG. It has become.

That is, in the impact absorbing aid for human body, it is detected that the wearer 1 wearing the wearable body 10 accidentally falls from a high place and the feet and buttocks of the wearer 1 are all separated from the scaffold by the pressure-sensitive sensor 30. When the acceleration sensor 40 detects that the acceleration acting on the human body has become smaller than the gravitational acceleration (S2), the timer 51 starts counting time (S3). 30 and acceleration sensor 4
If the detection of 0 is not canceled (S4, S5) and a predetermined time T (for example, 0.4 seconds) has elapsed (S6), the charging device 2
0 is activated (S7). Thereby, each air bag 11, 1
2 and 13 are filled with high-pressure gas, and each air bag 11, 1
2, 13 expand. At that time, each air bag 11, 12, 1
3, each cover 10a, 10
b, the magic tape 10c is removed, and as shown in FIG. 4, the surroundings of the wearer's 1 neck, back and waist are instantaneously covered by the air bladders 11, 12, and 13.
This absorbs the drop impact on the human body. In the operation of the control unit 50, if the detection by the pressure sensor 30 or the acceleration sensor 40 is canceled before the time T elapses (S4, S5), the timer 51 is reset (S4).
8) Return to step S1.

As described above, according to the shock absorbing aid for the human body of the present embodiment, both feet and buttocks of the wearer 1 are separated from the scaffold by the pressure-sensitive sensor 30 and the acceleration sensor 40
When it is detected that the acceleration acting on the human body becomes smaller than the gravitational acceleration, the air-supplying device 20 of each of the air bags 11, 12, and 13 is actuated.
When the acceleration acting on the human body changes when the feet or buttocks separate from the platform when sitting or jumping, or when using an elevator, going up or down stairs, or climbing over a step, etc. It is possible to reliably prevent a malfunction when the vehicle does not fall from the place. Also,
Since the cylinder 21 of the charging device 20 is opened by directly crushing the cylinder 23 with the explosive 23, there is no time loss due to the movement of the firing pin as in the prior art.
1 can be spouted instantaneously. In this case, the periphery of the gas inflow portion of the air bag 13 is protected by a protective member 13a.
Air bladder 1
3 can be reliably prevented. Further, there is an advantage that the number of components can be reduced because the conventional firing pin is not required, and that the use of the firing pin does not cause poor opening.

The above-mentioned human body shock absorbing aid is used not only for workers at high places but also for passengers when the motorcycle falls, and persons who are likely to fall when walking due to illness, obstacles or aging. It can also be used for shock absorption.

In a structure such as the acceleration sensor 40, chattering of contacts generally occurs easily. Therefore, if the measurement of the delay time T in the control is started from the last pulse of the chattering, the detection accuracy is improved. Can be achieved.

In the acceleration sensor 40, FIG.
As shown in FIG.
When the sphere 42 is at the neutral position away from the center, the sphere 42 performs a damping vibration as shown in FIG. At this time, the maximum amplitude for each half cycle is
If it is smaller than the gap of 4, 45, each electrode 4
4 and 45 do not come into contact with each other, and the detection state in which the electrical continuity is cut off is maintained. In this case, the gap A between the electrodes 44 and 45 shown by the solid line in FIG. 14 and the bending amount B due to the gravitational acceleration (1G) when only the elastic member 41 and the sphere 42 are used as shown by the dashed line in FIG. Assuming that they are almost equal to each other, if the state becomes smaller than the gravitational acceleration other than when falling, such as when using an elevator or going up and down stairs, intermittent conduction of irregular contacts frequently occurs, and it is determined that a fall has occurred. Becomes difficult. Therefore, the gap A between the electrodes 44 and 45 is made smaller than the flexure amount B of the vibrator (for example, when the flexure amount B is set to 1, the gap A is 0.8 or less), and a small change in acceleration acting on the sensor is obtained. If the position of the sphere 42 is not changed, the fall can be determined more accurately.

The gap A between the electrodes 44 and 45 is narrow,
Even if the electrodes 44 and 45 are in contact with each other at the maximum amplitude of every half cycle of the vibration, the function of detecting the intermittent state of the constant cycle is provided because the intermittent operation continues after repeating the intermittent operation of the fixed cycle. By adding to the control unit 50, it is possible to determine the falling state. However, 1
Assuming a vibration cycle of 0 to several tens of Hz, if several cycles are required until the fall is determined, a considerable distance of fall may occur during that period. Therefore, for example, when the bending amount B is 1, the gap A between the electrodes 44 and 45 is set to 0.5 or more so that the electrodes 44 and 45 do not contact each other at the maximum amplitude at least after about one cycle. It is possible to

As shown in (a), one end of the elastic member 61 is bent by the gravity acting on the sphere 62, and the electrode 64 on the sphere 62 and the electrode 65 on the sensor body 63 come into contact with each other. When the direction of gravity acting on the acceleration sensor 60 changes by 90 °, the other end of the elastic member 61 bends as shown in FIG. 15 (b), and the electrode 64 on the sphere 62 side and the electrode 65 on the sensor body 63 side change. Touch each other. That is, when the one end side and the other end side of the elastic member 61 bend in different directions, the electrode 64 on the sphere 62 can come into contact with the electrode 65 on the sensor body 63 from multiple directions. The support member 61a has a function of restricting the deflection of the bent portion of the elastic member 61. That is, when the acceleration acting on the sphere 62 at the time of dropping or the like becomes smaller than the gravitational acceleration (1 G), the electrode 64 on the sphere 62 separates from the electrode 65 on the sensor main body 63 as shown in FIG. Is to be detected.
