Fall accident high cost safety best of the present invention,

For example, the application of the vest type to the vest type that can be worn separately inside the work clothes, in particular winter and summer work clothes as an optimum embodiment, but if necessary, it can be applied to the overall work clothes fixed down to be.

In the present invention is applied to the vest as a means for effectively protecting the upper part of the body of the worker, especially the important organs, such as the heart during the fall accident, it will be applicable to both under, such as work.

As shown basically in FIG. 1,

Fall accident high cost safety best of the present invention as the main configuration, mainly to the safety best to protect the operator by detecting and expanding the fall, as a means of cooperating with the safety best (1), by interlocking as an electrical signal The management unit 100, which is managed as a management control unit at a separate place, is configured as an operation system.

That is, safety by having a safety best (1) to act as a basic mechanical actuator to protect the operator and a control unit 100 for indicating the location and the administrator to recognize the fall-sensitive signal transmitted from the safety best (1) safety The utility of the vest 1 is increased.

2 is a vest-shaped vest, which can be opened by a zipper (Z) or a button, etc., and preferably visually inspects the inner member and is below the other work clothes. It is a mesh rod-type garment having a storage space 5 between the front and rear surfaces so as to minimize the sense of foreign matter when worn on the fabric, and also serves as a storage space for storing a plurality of operating members.

In the drawing, the housing part C below the safety harvester 1 is configured to include an inflator expander 22 and an inflator drive switch unit 21 which will be described later.

The reason for employing the vest-type safety vest (1) in the present invention is configured in the vest for washing and checking, and can be worn overlapping under other work clothes when replacing the work clothes according to the working environment in the summer or winter On the other hand, according to the work schedule, this is to increase the applicability in the field by dismounting only the safety best (1) during non-altitude work.

As shown in FIG. 4, the safety best 1 is configured and worn in a laboratory, and one inflator B is illustrated.

The main control unit 10, which is housed in a pocket 2 or a separate storage space (not shown) of the safety harvester 1 and which will be described later, is preferably configured as a circuit board and houses the circuit board. It is used as a control part by accommodating in 11 and accommodating in the accommodating part, such as the bag 2 and so on.

In the above-mentioned safety best 1, the inflator bag B, which performs the same function as an airbag of a conventional car, is formed between the storage spaces 5 so as to protect the front and rear of the body from shocks and constitute a shock absorbing portion. It is manufactured and stored in various shapes and designs so as to cover the main part of the body.

The inflator bag (B) may be made of various shapes and materials according to the contour of the safety best (1), and may be made of a high density plastic cut to a shape that can buffer the main front and rear parts of the worker's body. will be.

As in the exemplary development view of FIG. 3,

Inflator expander 22 is fluidly connected to at least one inlet I of inflator bag B as expansion means to enable expansion.

The injection hole I is preferably a plurality of injection nozzle bodies for rapid expansion of the inflator bag B, but it may not be necessary depending on the size of the inner diameter of the injection hole I.

The inflator bag B is connected with an inflator inflator 22 such as a cylinder for storing gas for expansion. In the illustrated example, a cartridge-type gas cartridge V for compressing and storing gas such as carbon dioxide and high pressure nitrogen is stored. It is shown.

Between the inflator bag B and the inflator inflator 22 fluidly connected, an inflator drive switch 21 as an open / close switch such as an electric motor or a solenoid that performs mechanical rotation to open and close the flow path is mounted.

Typically, as shown in FIG. 5, the connecting body part N which rotates the electric motor M and encloses the flow path F between the inflator bag B and the inflator inflator 22 is mechanical. The means for opening and closing the unit is shown.

In addition, as another configuration of the inflator drive switch unit 21, as shown in FIG.

A primer 30 having a configuration such as that employed in an airbag of an automobile typical to the inflator bag B, and a normal gas generating unit 31 that generates gas by ignition upon ignition of the primer 30 are fluids. It can be connected and configured.

In this case, the primer 30 and the gas generating unit 31 are smaller than the cartridge-type gas cartridge V such as carbon dioxide, and emit gas for an extremely short time due to the explosion. Since the reaction time is shorter, it may be a more preferable configuration.

The main controller 10 transmits an operation signal to the inflator drive switch unit 21, which is an electric signal driver for driving the inflator expander 22,

In the case of the fall state according to the judgment of the comparator 12 and the comparator 12, which compares the response output from the drop sensitive sensor part 11 and the drop sensitive sensor part 11, which are acceleration sensors, with the set reference value, And a GPS position transmitter 13 for sending the GPS position value to the controller 100 at a spaced apart position as an RFID signal, and a driver 14 for generating a signal for driving the inflator bag B in the crashed state.

In the case of an operator's fall, the main control unit 10 determines that the comparator 12 is in the fall state in the comparator 12 based on the response value of the drop sensitive sensor unit 11, which is an acceleration sensor, and inflates the inflator bag B before falling to the ground. In order to achieve this, an electrical signal for driving the inflator inflator 22 is transmitted to the inflator drive switch unit 21, and the inflator drive switch unit 21 is connected to the inflator bag B, such as a gas cartridge V, or the like. By opening the inflator 22 of the inflator bag (B) is to be expanded immediately.

The variable acceleration in the fall state in which the drop sensitive sensor part 11, which is an acceleration sensor, must be sensitive, for example, takes about 1.75 seconds when dropped from the fifth floor height (about 15 m) in a typical environment. In case of design based on Atmega128's MCU, it was designed with the operation time of less than 1 second from the initiation of the induction sensor switch switch 21 to the initiation of the induction sensor switch 11 is the acceleration sensor.

The drop response in the drop response sensor unit 11 is an acceleration during vertical movement for moving up and down by moving up and down by a worker's stairway, a footrest to a height for a normal work, or by lifting a work elevator. It will be designed to detect the fall state if the acceleration value of the value exceeding the value, i.e., below the acceleration value is experimentally set and set as the reference value.

The impact to the worker during the fall is physically obtained as 'momentum = mass x speed' when the worker falls at a constant height, so the required size and inflator of the inflator bag (B) and the inflator to be used (22) ) Capacity, reaction rate, etc. can be obtained by physical calculation based on the experiment.

As a result of an exemplary experiment, when using a gas cartridge (V) filled with carbon dioxide, four air pads capable of absorbing the impact amount were designed and manufactured using the filling gas generated from two 16g cartridges. The amount of gas generated in the case of about 555.7 mL / g of gas at room temperature was generated, and about 17.8 L of two 16 g of gas were inflated to expand the inflator bag.

The fall high response signal from the main control unit 10 is received at the main computer of the control unit 100 having a receiving unit is provided at the designated position of the site receives the position of the operator of the work site from the GPS position transmission unit 13.

As in the example diagram of FIG. 7,

The computer of the control unit 100 displays the fall position P on the fall position value display 110 and the work site map 112 of the latitude and longitude coordinate values of the fall position by a display means such as a monitor T, In addition, as a warning light (111) on the monitor or a warning light not showing that the fall emergency is notified to the administrator, it is configured to be able to take immediate hospital transport and the like. Such signaling and operation are conventional techniques and will not be discussed in detail.

In the above-described configuration, the main controller 10 is configured as a separate component by configuring the MCU of the low-end type or mass production type on the circuit board.

As shown in the schematic diagram of Figure 8, various types of smart phones (S) that are widely used in recent years basically has a built-in gravity sensor that acts as a drop-sensitive sensor, GPS sensor to give a fall position value,

The signal transmission function to the comparator and the control unit 100 to determine according to the values of the gravity sensor and the GPS sensor can be easily configured by the application driven by the smartphone, so that the main controller 10 can be separately configured as a circuit board. It can be used by replacing the smartphone (S) and the application (A) possessed by the worker without the need.

However, in order to solve a problem such as a large-scale workplace or a large number of workers, or forgetting the driver's application, the main controller 10 of the crash accident high cost safety best of the present invention is configured. Of course, this is preferable in terms of reliability of operation.

The fall accident high cost safety best of the present invention has been described by applying to the work clothes of the best shape, but if necessary, the work clothes pants in the form of an auxiliary garment of the same improvement or by storing the inflator bag (B) in the work clothes themselves, Of course, it can be modified according to the characteristics.
