Fire hose lifting hanger with one-way locking structure

The present invention relates to a hook for lifting a fire hose having a one-way locking structure, and more specifically, when it is necessary to connect a fire hose from the ground to a high floor in order to extinguish a fire in a high-rise building, a fire hose connected to a fire hydrant or a fire truck By allowing them to be transported quickly and safely to high floors, it was possible to quickly extinguish fires.

Particularly, the present invention is a process of extinguishing a fire by configuring the part that joins the fire hose in the form of handcuffs so that it can be easily connected even when the fire hose (water) is contained inside the fire hose (the state where the fire hose is expanded) It relates to a hook for lifting the fire hose having a one-way locking structure that can be quickly and easily transport the fire hose being used in another floor.

In general, in buildings such as buildings and apartments, fire extinguishers, which are indoor fire extinguishing facilities, are installed on each floor to quickly extinguish them in the event of a fire.

However, when a fire hydrant on the floor cannot be used due to a fire, or when a fire hydrant is not installed on the floor, or when a fire hydrant is installed but does not operate due to the management hole, Firefighters who fight fires must get firefighters from other floors to fight the fire.

For example, if you need to extinguish a fire by connecting a fire hose from the ground hydrant or fire truck to the floor, connect one side of the fire hose to the fire hydrant or fire truck, and the other side of the fire hose is tied with a rope and then ropes By pulling and raising it to a high floor, a fire hose can be connected from the ground to the high floor, and firefighters on the ground can be supplied to the high floor to extinguish the fire.

On the other hand, when the fire is extinguished, the fire hose expands roundly in the process of supplying the fire water, and as a result, the rope portion tied to the fire hose also expands.

Thereafter, when the fire is extinguished and the supply of firefighters is stopped, the expanded fire hose is reduced to its original state, and when the fire hose is recovered in this state, the rope portion that bound the fire hose is in an extended state, and thus the expanded rope The fire can be separated from.

As described above, when the fire hose tied to the rope is released from the rope, there is a problem that the fire hose including the fire nozzle falls from a high floor to cause damage.

Conversely, when the rope is tightly tied to the fire hose, excessive pressure is applied to the rope tied portion in the process of supplying fire water, which causes firefighters to fail to control the fire hose, resulting in smooth fire suppression. There may be cases where it cannot be achieved.

Such a problem may occur more and more frequently when supply and stoppage of firefighters is repeated in the process of extinguishing a fire.

8 to 11 are diagrams for explaining methods using FIG. 1.

The example of the hook for lifting a fire hose having a one-way locking structure according to the present invention can be variously applied, and the most preferred embodiment will be described below with reference to the accompanying drawings.

1 is a view showing an embodiment of a hook for lifting a fire hose having a one-way locking structure according to the present invention, Figure 2 is a partially enlarged view for explaining the hose support shown in Figure 1 in more detail, Figure 3 is 2 is a view showing an embodiment of the unlock button shown in FIG. 2, and FIG. 4 is a view showing another embodiment of FIG.

Referring to Figure 1, the one-way locking structure having a fire hose lifting hook (A) includes a hose support portion 100 and the rope connection portion 200.

The hose support portion 100 is composed of a one-way locking structure and is supported by being coupled so that the fire hose can be detached, and may include a fixed support portion 110, a rotation support portion 120, and a one-way locking portion 130.

Here, the one-way locking structure may include a structure in which rotation in one direction is possible and rotation in the opposite direction is impossible, such as handcuffs.

Thus, the fixed support 110 may be configured integrally with the rope connecting portion 200, and the rotation support 120 may be configured to be rotatable to the fixed support 110.

In addition, the one-way locking unit 130 is configured to enable the rotation support unit 120 to rotate in one direction (counterclockwise in FIG. 1) and to be hung in the other direction (clockwise in FIG. 1). You can.

The structure and structure of the one-way locking unit 130 may be the same or similar to that of a general handcuff, and may be variously modified according to the needs of those skilled in the art, so it is not limited to a specific one.

On the other hand, since the spray nozzle configured in the fire hose is made of metal and has a considerable weight, in the process of transporting the fire hose to a high floor using the hook (A) shown in FIG. 1, the spray configured in the end portion of the fire hose The fire hose may be pulled downward due to the weight of the nozzle.

Thus, the present invention, as described above, in order to prevent the fire hose from falling during the transport process, it is possible to form the corrugated projections (113, 123) in the inner direction of the fixed support 110 and the rotation support 120 .

At this time, the corrugated projections 113 and 123 may be formed to have a relatively smaller radius of curvature of the convex portion (protrusion) than the radius of curvature of the concave portion.

As described above, by forming the radius of curvature of the convex portion relatively small, it is possible to prevent the fire hose from flowing or slipping by the convex portion.

In addition, as shown in FIG. 2, the hose support part 100 may further include an unlock button 114.

As described above, the one-way locking unit 130 prevents rotation in the other direction (clockwise in FIG. 2) in a state in which the rotation support unit 120 and the fixed support unit 110 are combined to form a circle, thereby preventing fire. It plays a role to make the hose stable.

Thereafter, when the fire suppression is completed, the connected fire hose must be disconnected, and the unlock button 114 has a one-way locking so that the rotation support 120 supported by the one-way locking unit 130 is rotated in the other direction. It can serve to release wealth.

For example, the one-way locking unit 130, as shown in Figure 2, if the locking piece 131 can be configured, the locking blade 121 is configured at the end of the pivot support 120, the locking piece (131) ), It is possible to limit the rotation support 120 to rotate in the other direction.

At this time, as shown in (a) of FIG. 3, the inclined surface 114a may be formed under the unlock button 114, and the engaging piece 131 is also in close contact with the inclined surface 114a of the unlock button 114. An inclined surface 131a may be formed.

Thus, as shown in (b) of FIG. 3, when the unlock button 114 is pressed, the engaging pieces 131 are in one direction (left in FIG. 3, due to the interaction of each of the inclined surfaces 114a, 131a). (Bottom direction).

As described above, when the engaging piece 131 moves in one direction, the holding force of the engaging blade 121 by the engaging piece 131 is released, and the rotating support unit 120 is rotated in the other direction, and the fire hose is turned off. Can be separated.

On the other hand, when the fire crew presses the unlock button 114 by mistake or carelessness in the process of extinguishing the fire, the fire hose may be separated and difficulty in extinguishing the fire may occur.

Accordingly, as shown in FIG. 4, the present invention may further configure a button protection cover 115 for preventing the unlock button 114 from being pressed by mistake or carelessness.

To this end, the hose support portion 100 may further form a groove-shaped coupling portion 116 to which the button protection cover 115 can be coupled.

In addition, in order to enable the button protection cover 115 to be stably coupled to the engagement portion 116, an engagement groove 116a may be formed in the engagement portion 116, and an engagement groove may be provided in the button protection cover 115. Coupling protrusions 115a that are forced into (116a) may be formed.

Therefore, in order to press the unlock button 114, the firefighter must remove the button protection cover 115 by using sufficient force, so that the button protection cover 115 can be removed only in a state sufficiently recognized by the firefighter. You can.

The rope connection part 200 is integrally formed with the hose support part 100, and a lifting rope for transporting a fire hose is connected, and as shown in FIG. 1, a rope connection hole 201 may be formed.

On the other hand, since the firefighter wears a fire jacket of considerable thickness at the fire site, the movement of the finger may be relatively slow, and in the process of combining the fire hose with the hook (A) of the present invention while wearing the fire suit. , It may be difficult to hold the hook (A) stably.

In order to solve this, when forming the grip portion 210 as shown in Figure 1, it is possible to prevent the rope connecting portion 200 from sliding in the process of connecting the fire hose to the hose support portion 100, the firefighter, The fire hose can be quickly coupled to the hook (A) for lifting the fire hose with a one-way locking structure.

In addition, the hanger (A) of the present invention, at least one of the hose support portion 100 and the rope connection portion 200, the glass shattering portion 111 may be formed with a protruding tip.

For example, as shown in FIGS. 1 and 2, the glass crushing part 111 may be formed on the fixed support part 110.

Accordingly, the firefighter can crush a glass window or a glass door by using the glass crushing unit 111 in the process of extinguishing the fire, if necessary.

In addition, the veneer hole 112 may be formed adjacent to the glass crushing unit 111, and the purpose of forming the veneer hole 112 will be described in more detail below.

On the other hand, the hook (A) for lifting the fire hose having a one-way locking structure of the present invention, the manufacturing tolerance of the rotating part (unsigned) in which the fixed supporting part 110 and the rotating supporting part 120 are rotated, the engaging blade 121 ) And the shape and size of the triangular blade of the engaging piece 131, the structural features of the one-way locking portion 130, etc., the force supporting the fire hose may be somewhat reduced.

Hereinafter, a method for compensating for the reduction in support capacity for such a fire hose will be described.

5 is a view showing another embodiment of FIG. 1, FIG. 6 is a view for explaining the pressing support shown in FIG. 5, and FIG. 7 is a view showing another embodiment of FIG. 6. Here, Fig. 6 (b) is a view for explaining the operation in the cross section of the line 'a-a' shown in Fig. 6 (a), Fig. 7 (b) is' a shown in Fig. 7 (a) It is a diagram explaining the operation in the cross section of the -a 'line.

Referring to Figure 5, the hook (A) of the present invention may further constitute a pressing support (300).

The pressurization support 300 is configured for at least a part of the hose support 100, to pressurize the fire hose, as shown in Figure 5 can be coupled to one outer surface of the fixed support 110, one of ordinary skill in the art It may be configured in the interior of the fixed support 110, as required. Of course, it is natural that the pressing support 300 may be configured on one side of the outer surface or the inside of the pivoting support 120.

At this time, in order to pressurize and support the fire hose, the pressurizing support unit 300 may have a corrugated projection 323 identical or similar to the corrugated projection 113 formed on the fixed support 110.

Looking more specifically, as shown in Figure 6 (a), the pressing support 300 may include a main body 310, a supporting blade 320, and an elastic pressing hole 330.

The main body 310 constitutes the outer shape of the pressing support part 300, and can be fixed to one side surface of the fixing support part 110 as shown in FIG. 5, and the support blade 320 is coupled to slide inside. A slit-like space (unsigned) can be formed.

The support blade 320 is coupled to be movable in the inner direction (circular center direction formed by the fixed support and the rotation support), and may be coupled to a slit-shaped space formed in the body 310 as described above. .

In particular, the support blade 320 may be coupled to the body 310 so that the corrugated projection 323 protrudes outward in the inner direction.

The elastic pressing portion 330 is to press the support blade 320 inward by an elastic force, and in order to provide the same elastic force in a plurality of contact portions, it may be configured as a plate spring.

Thus, the hook for lifting the fire hose having a one-way locking structure of the present invention (A) prevents a decrease in the force supporting the fire hose due to structural structural features such as manufacturing tolerances, and in the process of extinguishing the fire It can support the fire hose more stably.

On the other hand, when the water pressure supplied to the fire hose is greater than the elastic force of the elastic pressing part 330, as shown in Fig. 6 (b), the support blade 320 can be moved into the interior of the body 310, this phenomenon Due to this, a phenomenon in which the aforementioned support force decreases again may occur.

In order to compensate for this, the hook (A) of the present invention may further include a blade fastener 340 as shown in FIG. 7.

The blade fastener 340 is to limit the movement of the support blade 320, as shown in Fig. 6 (b), by limiting the movement of the support blade 320 in the outer direction (right direction in Fig. 6) In the process of extinguishing the fire, the fire hose can be supported more stably.

More specifically, the blade fastener 340 may be configured to be movable in the vertical direction on the outer surface of the main body 310, and at one end portion, a fixed support portion 341 for limiting the movement of the support blade 320 Can be configured. Here, the fixed support portion 341 may be formed of a triangular blade having the same shape as the engaging blade 121 and the engaging piece 131 shown in FIG. 2, and the outer surface of the supporting blade 320 has a triangular shape corresponding to the triangular blade. Grooves may be formed.

Thus, as shown in Figure 7 (b), by adjusting the position of the blade holder 340, it is possible to selectively limit the movement of the support blade (320).

Hereinafter, the methods of using the hook for lifting a fire hose having a one-way locking structure of the present invention described above will be described.

8 to 11 are diagrams for explaining methods using FIG. 1.

Referring to FIG. 8, in the event of a fire, the fire fighter moves to the fire site while carrying the hook (A) for lifting a fire hose having a one-way locking structure, and when he arrives at the fire site, he or she carries the fire hook. A lifting rope R may be connected to the rope connection part 200 of (A).

For example, when a firefighter located on a high floor lowers a lifting rope (R) to the ground, the firefighter located on the ground penetrates the end of the lifting rope (R) through the rope connection hole (201), then knits, etc. Do not fall with a tie.

Then, after placing the fire hose (H) between the fixed support 110 and the rotation support 120, by fixing the rotation support 120 as shown in Figure 9, it is possible to mount the fire hose (H) have.

Of course, the firefighter can change the connection order of the fire hose (H) and the lifting rope (R), connect the fire hose (H), and then connect the lifting rope (R) to the rope connection hole (201). Of course it is.

Thus, when the fire hose (H) is mounted on the hook (A) of the present invention, the fire crew located on the high floor by pulling the lifting rope (R), it is possible to move the fire hose (H) to the high floor.

Then, when a firefighter (water) is supplied to the fire hose (H), the fire hose (H) expands, and at this time, the convex portions of the corrugated projections (113, 123) support the circumference of the fire hose (H). The lifting hole for lifting the fire hose having a way locking structure (A) can maintain a state connected to the fire hose (H).

When the extinguishing of the fire is completed, the fire hose H is moved to the lower floor in the reverse order of the above-described sequence, and then separated from the hook A for lifting the fire hose having a one-way locking structure to the original state. Can be stored.

Therefore, in the event of a fire, the fire fighter can quickly suppress the fire by moving the fire hose H on the ground to a desired height using the hanger A carried by him.

For example, in the process of extinguishing a fire using fire water (water) at a fire site, the fire hose H may move atypically due to the supply pressure of the fire water, and such movement may prevent the nozzle from facing the desired direction. Occasionally, there may be cases where smooth fire suppression cannot be achieved.

In order to solve this problem, as shown in Figure 10, the upper can be supported by using a rope (R1) used to move the hook (A) to a high floor, the lower part is a carabiner connected to another rope (R2) ( After the CB) is connected to the veneer hole 112, the upper and lower portions can be pulled to simultaneously support them.

Through such a process, the movement of the fire hose (H) and the fire hose lifting hook (A) having a one-way locking structure in the process of supplying fire water during fire fighting can be minimized and stable fire extinguishing can be achieved. .

On the other hand, the hook for lifting the fire hose having a one-way locking structure of the present invention (A) can be used not only to raise the fire hose (H) to a high floor, but also to allow the firefighters to quickly escape in the event of an emergency. This will be described below.

Referring to Figure 11, in connecting the rope (R) to the rope connecting hole 201 formed in the rope connecting portion 200 of the hook (A) for lifting the fire hose having a one-way locking structure, the rope (as before) Rather than connecting the end of R) to fold through the central portion, it is possible to connect the carabiner (CB) configured in the escape belt (B) to the pierced rope (R). Here, the escape belt (B) may be configured to be worn by a firefighter or the like on a waist or shoulder, and may be changed into various shapes or configurations according to the needs of those skilled in the art.

Therefore, the firefighters and the like can safely escape to the ground while adjusting the descending speed using the hook (A) of the present invention while wearing the escape belt (B).

As such, the hanger for lifting a fire hose having a one-way locking structure of the present invention (A) can be utilized not only in the field of fire fighting and fire fighting supplies, but also in a similar field or related field.

For example, as in the prior art 1, an indoor fire extinguishing facility, a fire hydrant, can be used for storing fire hoses.
