Description

Drop experiencing apparatus

[0001] The present invention relates to a fall experience apparatus capable of promoting safety awareness by feeling a sense of fear of falling and feeling the importance of a seat belt during a fall, and more particularly, The fall experience apparatus is constructed so as to reduce the fall speed in a manner of a fall.

In recent years, it is still in a state of being unable to escape from the damage of various types of accidents due to the safety insufficiency of the related organizations and citizens. Especially, the conventional accidents at the construction site are frequently occurred even though the safety management staff resides It is true.

Accidents at these construction sites are caused by safety insufficiencies and carelessness of field officers, safety supervisors and above all, workers working on the site. According to the data, disaster at the construction site is caused by falling, collision, Of the total disasters accounted for more than 70% of the total disasters, and these disasters were those that could have greatly reduced the damage if the concerned or the accused parties had paid little attention in advance and were careful, It is no exaggeration to say that the damage is increasing every year.

In order to prevent such accidents at the construction site, thorough safety management and preliminary education are necessary. However, most of the construction sites are not pre-education, and legal sanctions are not realistic, Many workers are exposed to various accidents in an unprotected state. Therefore, there is a constant need for various safety education before work.

Especially, in the case of a large scale work site or a high - level work site, there is always a danger of a fall accident. Therefore, it is demanded not only safety consciousness of workers but also pre - education more urgently.

However, in most workplaces, the safety management officer unilaterally delivers to the worker, or simply the injection training, and because of the limitation of the training, the worker himself is not taking the risk of the accident seriously, .

In order to solve such a problem, a falling experience apparatus having various structures for feeling the fear of fall has been proposed. In the conventional fall experience apparatus, the experience of falling down by adjusting the length of the strap connected to the subject is not reached Is often used. In the case where the fall is stopped suddenly immediately before the falling person touches the ground, there is a possibility that the body of the experiencer may become unreasonable or injured. Further, when the brake is used to stop the experimenter immediately before reaching the ground, there is a problem that maintenance costs are increased because parts such as a brake pad must be periodically replaced.

1 is a front view of a fall experience apparatus according to the present invention.

The fall experience apparatus according to the present invention relates to a fall experience apparatus that can inspire a sense of safety by making a feeling of fear of a fall to an experienced person and make the user feel the importance of the seat belt 700 when falling. And is constructed so as to gradually reduce the fall speed of an experienced person using the eddy current brake principle.

That is, the fall experience apparatus according to the present invention includes a plurality of column frames 110 vertically installed on the ground, a structure 100 composed of a ceiling frame 120 to be coupled to the upper ends of the column frames 110, And a first magnet 320 and a second magnet 330 which are mutually spaced apart from each other in the horizontal direction and whose polarities are different from each other on the opposite surfaces of the guide bar 200, A lifting block 300 coupled to the guide bar 200 so as to be slidable along the guide bar 200 and a safety belt 700 worn by the user and the lifting block 300, The pulling wire 600 moves the lifting block 300 in the longitudinal direction of the first magnet 320 and the second magnet 330 when the user moves down and the lifting block 300 is moved The gold It is configured to include a plate 500.

A center pulley 610 is provided at the center of the ceiling frame 120 and a side end pulley 620 is provided at an outer end of the ceiling frame 120. A lower pulley 630 The tow wire 600 has one end in the longitudinal direction coupled to the seat belt 700 and the other end in the longitudinal direction extends downward across the center pulley 610 and the side pulley 620, (630) and extends upward to be coupled to the lift block (300). At this time, a separate winding wire 400 is connected to the lifting block 300 and a winding roller 410 around which the winding wire 400 is wound is coupled to the lifting block 300 in a rotatable manner And a driving motor 420 for rotating the winding roller 410 are further provided.

When the user moves the driving motor 420 to rotate the winding roller 410 in the direction in which the winding wire 400 is wound after the wearer wears the seat belt 700 on the ground, The lifting wire 400 is lifted by a length wound on the winding roller 410 and the seat belt 700 connected by the pulling wire 600 is also raised so that the wearer wearing the seat belt 700 It is spaced upward from the ground.

Thus, when the driving force of the driving motor 420 is released in a state where the experimenter is spaced upward from the ground, the experimenter can experience falling down due to free fall due to its own weight. On the other hand, the braking force for pulling the traction wire 600 should be generated so as to reduce the fall speed of the experiencer when the experient approaches the ground level, since the trainer may be injured if the trainer falls free to the ground. The frictional pad and the traction wire 600 are severely abraded when the friction pad is closely attached to the traction wire 600 to hold the traction wire 600 like the falling experience device, To be replaced periodically. Generally, the friction pad is operated to be in close contact with the pulling wire 600 by an external power source. If a power failure occurs or the friction pad does not operate normally, the falling speed of the experiencing person can not be reduced. .

In addition, when the trainee 600 is prevented from falling by the physical frictional force, the experiencing person who has fallen freely can be stopped suddenly. In this case, the wearer's body (more precisely, There is a problem in that a strong pressing force is momentarily applied to the region of the wearer's body.

The fall experience apparatus according to the present invention can prevent such a problem, that is, even if a power failure occurs, it is possible to prevent a fall of an experienced person and to gradually reduce the fall speed of the experienced person, There is the biggest feature of the configuration.

That is, when the user falls down in the free falling state in the state shown in FIG. 1 and the lifting block 300 connected to the seat belt 700 is pulled down by the pulling wire 600, The metal plate 500 fixed to the lower side is positioned between the first magnet 320 and the second magnet 330 of the lifting block 300 and the braking of the eddy current brake system is performed, .

The eddy-current brake braking system is a braking system in which the metal is magnetized by an instantaneous current when the metal is inserted between the N pole and the S pole of the magnet and the braking force is generated by using the repulsive force between the magnetic field of the metal and the magnetic field of the magnet. . Such an eddy current brake braking system is commercialized in a gyro drop play apparatus and the like, and a detailed description of the principle of the eddy current brake braking system will be omitted.

As described above, when the eddy current brake braking system is used, normal braking can be performed even if a power failure occurs, and the metal plate 500 is not in direct contact with the first magnet 320 or the second magnet 330, There is an advantage in that it is not necessary to replace parts such as the magnet 500 and the magnet, that is, the durability is excellent and the maintenance cost is reduced.

Meanwhile, in the case of the fall experience using the fall experience apparatus according to the present invention, since the fall is accelerated by free fall when the fall falls, the lift block 300 connected to the seat belt 700 also accelerates do. At this time, since the lift block 300 is decelerated by the magnetic field between the first magnet 320 and the second magnet 330, a higher deceleration effect can be obtained as the acceleration of the lift block 300 is larger. That is, as the fall rate of the experienced person is higher, the effect of slowing the fall rate of the experienced person becomes greater, and various safety accidents can be reliably prevented.

4 is a perspective view showing a coupling structure of the metal plate 500 and FIG. 5 is a sectional view of the metal plate 500 when the lift block 300 is lowered. FIG. Fig.

The braking force is generated by a pair of magnets (the first magnet 320 and the second magnet 330) and the metal plate 500 inserted therein, and the braking force of the magnet and the metal plate 500 As the number increases, the braking force increases.

Accordingly, the vertical movement block 300 may include a plurality of vertical plates 310 spaced apart from each other and vertically stacked in a horizontal direction so as to generate a greater braking force, and a plurality of vertical plates 310 A fastening bar 340 coupled to the vertical plate 310 so as to penetrate in the horizontal direction and integrally connecting the plurality of vertical plates 310, a guide bar 200 coupled to an outer surface of the vertical plate 310 located at the outermost position, And a slide unit 350 sliding along the guide bar 200. The first magnet 320 and the second magnet 330 are connected to each other by two adjacent And the vertical plate 310, respectively.

At this time, a plurality of the metal plates 500 are also inserted between the pair of magnets. For example, in the case where four vertical plates 310 are provided and three pairs of the first magnet 320 and the second magnet 330 are provided as in the present embodiment, the metal plate 500 is formed as a pair The first magnet 320 and the second magnet 330, respectively.

When three magnets are provided and three metal plates 500 are provided, an advantage is obtained that three times of braking force can be obtained compared to the case where only one magnet is provided and only one metal plate 500 is provided. Of course, the number of the first magnet 320, the second magnet and the metal plate 500 may vary according to various conditions such as the characteristics of the fall experience apparatus, the weight of the experimenter, the length of the metal plate 500, And can be variously changed.

4, the lower end of the metal plate 500 is fixed to the seating plate 140 so as to stably maintain the vertically erected state without being tilted or swayed to one side during the lifting and lowering of the lifting block 300 And is fixed by the fixed frame 130 which is seated and the upper side thereof is bent in a 'C' shape.

Meanwhile, the fall experience apparatus according to the present invention can be set so that the driving force of the drive motor 420 is automatically released when the experimenter is pulled up to a certain height, that is, the fall of the experimenter is performed.

As described above, when the experimenter is lifted up to a certain height, the lifting block 300 is lifted up to a certain height. Thus, when the lifting block 300 is lifted up to a preset height, And a switch (not shown). At this time, the switch can be applied to various kinds of switches such as a limit switch for applying the height of the lifting block 300 as a pressure or an optical sensor or a magnetic sensor for sensing the height of the lifting block 300 as light or magnetic force.

The driving motor 420 rotates the winding roller 410 in a direction in which the winding wire 400 is wound so that the driving motor 420 rotates the winding roller 400 in a direction And may be set to release the rotational force applied to the winding roller 410 when it is detected that the block 300 has risen to a preset height.

Therefore, an experiencer using the experience fall device according to the present invention can experience a fall without any special operation, and the height at which fall starts can be set to a specific height, thereby enabling a more effective fall experience.

6 is a front view of the second embodiment of the fall experience apparatus according to the present invention.

The fall experience apparatus according to the present invention can be configured so that the experience can be dropped even without a separate winding roller 410 or a drive motor 420 for pulling up the experiencer. That is, in the fall experience apparatus according to the present invention, an addressee band 800 is provided below the center pulley 610, so that an experienced person can jump into the addressee base board 800 and jump down to experience a fall . The addressee 800 may be provided with a ladder or a stairway so that the experient can directly ascend to the addressee 800.

At this time, the pulling wire 600 has one end in the longitudinal direction coupled to the seat belt 700 and the other end in the longitudinal direction extends downward across the center pulley 610 and the side pulley 620, As shown in FIG. The metal plate 500 inserted between the first magnet 320 and the second magnet 330 included in the lifting block 300 is fixed to the upper side of the lifting area of the lifting block 300.

6, the traction wire 600 pulls up the lifting block 300, and when the lifting block 300 is lifted up from the lifting block 800, The metal plate 500 is inserted between the first magnet 320 and the second magnet 330 to generate a braking force for reducing the fall speed of the user.

The winding roller 410 and the driving motor 420 can be omitted when the lifting block 300 is raised and the braking force is generated when the user jumps from the address table 800. Thus, It is advantageous in that it is not limited to the use place as well as the maintenance cost is reduced since the power source for raising the experient is not required.
