1 to 4, the lifesaving parachute 10 according to an embodiment of the present invention may be a device for implementing a lifesaving in the event of a disaster such as a fire in a high-rise building.

In one example, the lifesaving parachute 10 may be fixed to the human body by a fixing member such as suspenders.

For example, the lifesaving parachute 10 may include a wing part 100 that receives air resistance when falling, and a cover part 200 that receives the wing part 100.

For example, the wing unit 100 may be configured to lower the fall rate of the person by receiving the resistance of the air is spread out from the cover unit 200 when falling.

For example, the cover part 200 may be configured to accommodate the wing portion 100 to protect the wing portion 100 from an external environment at normal times.

For example, the cover part 200 may be fixed to the human body by the fixing member such as suspenders.

For example, the wing portion 100 may be fixed to the cover portion 200 by a connection member such as a hanging line.

Here, for example, the cover part 200 may be provided with a cover part 210 that is unfolded by an external force and exposes the wing part 100 accommodated in the cover part 200 to the outside.

To explain this in more detail, as shown in FIG. 2, for example, the cover part 200 may include the cover part 210 covering the wing part 100.

For example, the cover part 210 may be configured to cover the wing part 100 disposed on the cover part 200.

For example, the cover part 210 may be moved by an external force to cover the wing part 100, or may be exposed by the external force to expose the wing part 100 to the outside.

For example, the cover part 210 may include a first cover part 211 covering the upper side of the wing part 100, a second cover part 212 facing the first cover part 211, and the wing part. A third cover part 213 covering one side of the part 100 and a fourth cover part 214 covering the other side of the wing part 100 may be provided.

For example, the first cover part 211, the second cover part 212, the third cover part 213, and the fourth cover part 214 are overlapped with each other by at least a part of the wing part 100. ) Can be covered.

For example, each of the first cover part 211, the second cover part 212, the third cover part 213, and the fourth cover part 214 may be a first locking part 310 to be described below. ) May be disposed in the arrangement hole (H).

Here, for example, the cover part 200 may further include an spreading portion A that applies a force to the cover portion 210 in a direction in which the cover portion 210 is unfolded.

For example, the spreading portion A may be a rod having elasticity in a direction in which the cover portion 210 is unfolded so as to expose the wing portion 100 to the outside.

For example, the cover part A is elastically restored when the first locking part 310 to be described below releases the cover part 210 so that the cover part 210 is unfolded so that the cover part 210 is unfolded. ) Can be applied to external force.

For example, the spreading part A may be disposed in each of the first cover part 211, the second cover part 212, the third cover part 213, and the fourth cover part 214. have.

As a result, the first cover portion 211 may be extended upward by the spreading portion A, and the second cover portion 212 may be spread downward in the downward direction by the spreading portion A. The third cover part 213 and the fourth cover part 214 may be unfolded in the horizontal direction by the spreading part A, thereby exposing the wing part 100 to the outside.

Therefore, the wing part 100 may be released from contact with the cover part 210 to be released from restraint of the cover part 210.

Here, as an example, the cover part 200 may further include a pressing part 250 for pressing the wing part 100 exposed to the outside in the upward direction.

For example, the pressing unit 250 may be configured to apply an external force to the upper portion with respect to the wing portion 100 disposed on the cover portion 200 so that the wing portion 100 bounces upward. have.

For example, the pressing unit 250 may be an elastic spring.

That is, the pressing unit 250 may be configured to apply an elastic restoring force to the wing unit 100 so that the wing unit 100 bounces upward.

Here, as an example, the cover portion 200 is moved upwards by the pressing of the lower plate 230 and the pressing portion 250 for supporting the pressing portion 250 to support the wing portion 100. The upper plate 240 may be further provided.

For example, the pressing unit 250 may be disposed between the lower plate 230 and the upper plate 240, and the pressing unit 250 may have elastic restoring force in the upper direction with respect to the upper plate 240. Can be added.

The wing portion 100 may be seated on an upper side of the upper plate 240, and thus, when the pressing unit 250 exerts an external force in the upper direction with respect to the upper plate 240, The side plate 240 may bounce in the upward direction to exert an external force in the upward direction with respect to the wing portion 100.

As a result, the wing portion 100 may be lifted up by the pressing portion 250 in the upper direction.

Here, for example, the cover part 200 may further include a guide plate 220 for guiding the movement of the upper plate 240.

For example, the guide plate 220 allows the upper plate 240 to move in the upper direction when the upper plate 240 is moved in the upper direction by the pressing unit 250, The upper plate 240 may be configured to limit the movement in the horizontal direction.

That is, the guide plate 220 may be configured to guide the movement of the upper plate 240 so that the upper plate 240 can be moved only in the upper direction, not the horizontal direction.

To illustrate this in more detail, as shown in FIG. 4, the guide plate 220 includes an insertion part 221 into which the upper plate 240 is inserted, and the upper plate 240 is the The protrusion 241 may be inserted into the insertion portion 221.

For example, the insertion portion 221 may be continuously formed in the upward direction, and the protrusion 241 may be inserted into the insertion portion 221 to limit movement in the horizontal direction, but in the upward direction. May be allowed to move.

Hereinafter, the operating state of the lifesaving parachute 10 will be described in more detail with reference to FIG. 3.

3 is a cross-sectional view of the wing unit 100 is accommodated in the cover unit 200 is not exposed to the outside.

For example, the lifesaving parachute 10 may include a first locking part 310 that locks the cover part 210 so that the cover part 210 does not spread, and the upper plate 240 moves upward. The second locking part 320 for locking the upper plate 240 and an external force applying part for releasing the locking of the first locking part 310 and the second locking part 320 by an external force may be further included. Can be.

For example, the first locking part 310 may be disposed in an arrangement hole H formed by the cover part 210 to prevent the cover part 210 from being unfolded.

For example, when the first locking part 310 is moved by an external force while the cover part 210 is locked, the first locking part 310 may no longer lock the cover part 210, and as a result, the cover part 210 may not be locked. The part 210 may not restrain the wing part 100 from being restrained by the first locking part 310.

For example, the second locking part 320 may be connected to the upper plate 240 to prevent the upper plate 240 from being moved in the upward direction by the pressing unit 250.

For example, when the second locking unit 320 is moved by an external force while the upper plate 240 is locked, the second locking unit 320 may no longer lock the upper plate 240. The side plate 240 may be moved away from the restraint of the second locking part 320 by the pressing part 250 in the upward direction.

For example, the external force applying unit may be configured to receive an external force from a person and transmit the external force to the first locking unit 310 and the second locking unit 320.

When the first locking part 310 and the second locking part 320 receive external force from the external force applying part, the first locking part 310 and the second locking part 320 are moved in the state of FIG. 3 to cover the cover part 210 and the upper plate 240. The locking function that constrains may no longer be implemented.

In one example, the external force applying unit may be composed of a wire.

For example, the external force applying unit is a gripping portion (B) to receive an external force from a person, a first wire (L1) connected to the gripping portion (B), one end is connected to the first wire (L1) and the other end is A second wire L2 connected to the first locking part 310 and a third wire L3 connected at one end thereof to the first wire L1 and connected to the second locking part 320 at the other end thereof. can do.

For example, when a person grips and pulls the gripping portion B by applying an external force, tensile force is transmitted to the second wire L2 through the first wire L1, and the second wire L2. The transmissive force may be transmitted to the first locking part 310 to implement the positional movement of the first locking part 310.

When the first locking part 310 is moved in position, the cover part 210 may be unfolded by the unfolding part A beyond the restraint of the first locking part 310 and no longer the wing part. 100 may not be constrained.

In addition, as an example, when a person grips and pulls the gripping portion B, a tensile force is transmitted to the third wire L3 through the first wire L1, and the third wire L3 is By transferring the tensile force to the second locking portion 320 may be implemented to move the position of the second locking portion (320).

When the second locking part 320 is moved in position, the upper plate 240 may be bounced up by the pressing part 250 from the restraint of the second locking part 320. The wing unit 100 may bounce up in the upward direction by the positional movement of the upper plate 240.

As a result, the wing portion 100 is released from the restraint of the cover portion 210, it can be unfolded faster as it is bounced up in the upper direction by the upper plate 240.

Here, as an example, when the external force is applied, the external force applying unit may release the locking of the second locking unit 320 after releasing the locking of the first locking unit 310.

In detail, the external force applying unit first moves the first locking part 310 to change the first locking part 310 to a state in which the cover part 210 is not restrained, and then the second locking part 310 is moved. By moving the locking part 320, the second locking part 320 may be changed without restraining the upper plate 240.

For example, when a person pulls the gripping portion B by 10 cm, the first wire L1 may immediately transmit a tensile force to the second wire L2, while the third wire L3 holds 5 cm. The tension can be transmitted when pulled.

As a result, when the gripping portion B is pulled from 0cm to 5cm, the first locking portion 310 may release the locking of the cover portion 210, and the gripping portion B may be 5cm to 10cm. When pulled out, the second locking part 320 may release the locking of the upper plate 240.

In order to realize this, for example, the first wire L1 and the second wire L2 may be directly connected, and the first wire L1 and the third wire L3 may be a variable member such as a roller. Indirectly connected by 400.

That is, when the first wire L1 is pulled from 0 cm to 5 cm, the tensile force is not transmitted to the third wire L3 but only the roller, and the first wire L1 is 5 cm to 10 cm. When pulled up to this point, the roller may transmit a tensile force to the third wire L3.

As another method, for example, the second locking part 320 receives an external force from the spreading part A unfolded by releasing the locking of the first locking part 310 of the upper plate 240. You can also unlock it.

In more detail, the first wire L1 may be connected only to the second wire L2 and may not be connected to the third wire L3.

That is, the first wire L1 and the third wire L3 may be independent.

Here, when the first wire (L1) transmits a tensile force to the second wire (L2), the first locking portion 310 releases the locking of the cover portion 210, the cover portion 210 May be unfolded by the spreading portion (A).

In this case, the external force applying unit may include a fourth wire L4 having one end connected to the spreading part A and / or the cover part 210 and the other end connected to the third wire L3.

That is, when the cover portion 210 is unfolded by the spread portion A, the external force generated from the positional movement of the spread portion A and / or the cover portion 210 is transferred to the fourth wire L4. ) May be transmitted, and the fourth wire L4 may transmit an external force to the third wire L3 so that the second locking part 320 no longer restrains the upper plate 240. have.

As a result, the external force applying unit may release the locking of the first locking unit 310 after releasing the locking of the first locking unit 310 when an external force is applied.

As described above, the life-saving parachute 10 according to an embodiment of the present invention can be easily unfolded by the wing portion 100 by simply pulling the grip portion (B) of the person, further, the wing portion As the 100 bounces upward in the upward direction and is unfolded at a high speed, it can be easily unfolded at a relatively low altitude to receive air resistance.

In the above description of the configuration and features of the present invention based on the embodiment according to the present invention, the present invention is not limited thereto, and various changes or modifications can be made within the spirit and scope of the present invention. It will be apparent to those skilled in the art that such changes or modifications fall within the scope of the appended claims.
