{HOOK FOR SUPPRESSING FIRES}

The present invention relates to hooks for fire suppression, and particularly, it is possible to adjust the length of the hooks to facilitate carrying and storage, and a T-shaped folding handle at the lower end of the pipe, And a fire-suppressing hook which can be used jointly.

When a fire occurs, the fire brigade is equipped with various equipment to extinguish the fire and sends it to the fire site to suppress the fire.

There are hooks in the fire suppression equipment. These fire suppression hooks are attached with hooks at one end of the long pipe. In case of fire, the fire brigade uses it to break the windows of the building, break the door lock, It is possible to rescue people by removing them.

However, such conventional fire suppression hooks have a problem that the length of the pipe supporting the hooks is so long that the fire brigade is inconvenient for carrying or storing the fire brigade. Especially, it is difficult for the fire brigade to enter the narrow space, It has a problem that it is difficult to extinguish a fire smoothly because the radius of rotation is large.

Since the fire-fighting hooks are made of a strong metal material for durability, the fire-fighting claws are relatively heavy, so they are frequently consumed by the fire brigade to use them alone. Therefore, the two people often use them in cooperation with each other. Since the pipe handle of the hook has a simple straight shape, there is a problem that it is inconvenient for the two people to hold it together.

The object of the present invention is to provide a fire extinguisher which can be easily moved by a fire brigade so that the entire length of the fire suppressing hook can be adjusted, And to provide a hook for easy fire suppression.

Another object of the present invention is to provide a fire suppressing hook which is provided with a T-shaped folding knob at the bottom of a pipe of a fire suppression hook, so that a plurality of fire brigades can hold a hook having a relatively large load.

The length regulating member includes a bolt having a thread and a head formed on the upper end of the lower claw pipe and having a plurality of cut-out grooves formed in the longitudinal direction at the upper end of the threaded pipe, and a lower claw pipe And a nut for fixing the upper claw pipe inserted into the lower claw pipe.

In addition, a knob portion made of a soft foam material is formed in the lower portion of the lower claw pipe to prevent slip.

A lower end of the lower claw pipe is provided with a T-shaped foldable handle rotatable by 90 degrees in a vertical direction from a horizontal direction to a vertical direction about a rotation axis.

The T-shaped foldable handle is engaged through two interlocking gears, each of which rotates around the rotary shaft. When the one handle of the T-shaped foldable handle rotates, the other handle is interlocked to rotate in a symmetrical direction.

In addition, when the T-shaped foldable handle is folded in the vertical direction by 90 degrees, a lower portion of the lower claw pipe is formed with a handle receiving groove for storing therein the T-shaped foldable handle inside the pipe, and the T- It is preferable that a handle protrusion is formed on the outer side of the T-shaped foldable handle so that the T-shaped foldable handle can be easily removed when the T-shaped foldable handle is received in the handle receiving groove.

In addition, it is desirable that a fluorescent part is formed on the upper claw pipe and the lower claw pipe so as to be distinguished in a dark place.

According to the present invention, the hooks for fire suppression are capable of controlling the length of the pipe with the hooks according to the situation so that it is easy to carry and store, and the fire brigade can be moved and used quickly.

In addition, according to the present invention, the hooks for fire suppression are provided with a T-shaped folding handle at the bottom of the handle of the pipe, so that when the T-shaped folding handle is opened, two firemen can hold the handle together, So that it can be done.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of a fire suppression claw according to an embodiment of the present invention, and FIG. 2 is a perspective view of a fire suppression claw having an extended length.

As shown in FIGS. 1 and 2, a fire suppression claw 100 according to the present invention includes a claw pipe 110 having a claw 120 at its upper end and a handle 140 at its lower end, A length adjuster 130 for adjusting the length of the pipe 110 and a T-shaped foldable handle 150 formed at the lower end of the claw pipe 110.

The hooking pipe 110 includes an upper hooking pipe 111 coupled with a hook 120 at an upper end thereof and a non-slip gripping part 140 coupled to the upper hooking pipe 111 to be inserted and withdrawn to the inside, The upper claw pipe 111 and the lower claw pipe 112 are adjusted in their entire length through the length adjuster 130 to be fixedly coupled.

In the embodiment of the present invention, the upper claw pipe 111, the lower claw pipe 112, and the length adjuster 130 are made of a metal material such as aluminum that can minimize the weight, instead of being high in strength. The hook 120 coupled to the upper end of the upper hooking pipe 111 is made of cast iron or steel having a large strength and weight so as to break the window glass, doors, locks and the like.

2, the upper claw pipe 111 and the lower claw pipe 112 have a length of about 5 m and can handle an obstacle at a long distance, When the upper claw pipe 111 is inserted into the lower claw pipe 112 as shown in FIG. 5A, the length of the upper claw pipe 111 is about half of the longest length, thereby facilitating transportation and storage.

The handle 140 formed at the lower portion of the lower claw pipe 112 is for preventing the fire suppression claw 100 from falling due to slippage when the fire brigade is used. And is formed on the outer side of the pipe. It is preferable that the handle 140 is formed to be about 1 m or so from the lower end.

The fire suppression claw 100 is often used for suppressing fire in a dark room where electricity is cut off due to the occurrence of fire due to its nature. Therefore, it is necessary to grasp the exact position of the hook 120 relatively far from the handle 140 in the dark space to suppress the fire. For this purpose, in the embodiment of the present invention, Fluorescent portions 111a and 112a are formed on the upper portion of the pipe 111 and the lower claw pipe 112 so that they can be identified in a dark place. The fluorescent portions 111a and 121a are formed by attaching a fluorescent tape or applying a fluorescent material to the upper portions of the upper and lower claw pipes 111 and 112, The formed fluorescent portion 112a is formed by an arrow directed toward the hook 120 so that the position of the hook 120 can easily be grasped by the firefighter.

The length adjuster 130 adjusts the overall length of the hooking pipe 110 by fixing the upper hooking pipe 111 inserted into the lower hooking pipe 112 through a screw connection. And FIG. 4 is an enlarged perspective view of the length control member. [FIG. 4] FIG. 4 is an enlarged perspective view of the length control member.

3 and 4, the length adjuster 130 according to the present invention includes a bolt 131 formed at an upper end of an upper end of a lower claw pipe 112, a nut 132 screwed to the bolt 131, (132).

The bolt 131 includes a thread 131a formed on the upper end of the lower claw pipe 112 and a head 131b protruding from the lower portion of the thread 131a. A plurality of (preferably three or more) cutting grooves 131c are formed in the longitudinal direction at the upper end of the lower claw pipe 112 in which the threads 131a are formed. 131c formed in the threaded portion 131a and restricts the progress of the nut 132 when the nut 132 is screwed. The head 131b may be integrally formed on the outside of the lower claw pipe 112 or may be coupled to the outside of the lower claw pipe 112 through a screw connection.

The nut 132 is inserted into the lower claw pipe 112 by reducing the upper diameter of the lower claw pipe 112 formed with the cutting groove 131c when the nut 132 is screwed with the thread 131a formed on the bolt 131. [ And serves to fix the upper claw pipe 111 in a fixed manner. Accordingly, when the nut 132 is inserted into the thread 131a of the bolt 131 and screwed into the bolt 131, the cutout groove 131c is tightened to reduce the upper diameter of the lower claw pipe 112 formed with the thread 131a It is preferable that the inner diameter of the bolt 131 is formed to be slightly smaller than the outer diameter of the thread 131a and that the bolt 131 in which the nut 132 is first inserted is formed gradually thicker from the upper end toward the head 131b.

The T-shaped foldable handle 150 formed at the lower end of the lower claw pipe 112 serves to provide a handle for allowing two firemen to use the relatively heavy fire suppression claw 100 together. The folding type grip handle 150 is used in a horizontal direction when necessary, and is stored in a lower gripping pipe 112 when unnecessary.

FIG. 5 is a perspective view of a fire suppressing claw with a T-shaped folding handle opened according to an embodiment of the present invention, and FIG. 6 is a view illustrating a state of use of a T-shaped folding handle provided in a fire suppressing claw.

As shown in FIGS. 5 and 6, the T-shaped foldable handle 150 according to the present invention has a structure in which the rotary shaft 152a provided inside the lower end of the lower claw pipe 112 is moved from the horizontal direction to the upper vertical direction The folding type knob 150 is pivoted about the rotating shaft 152a through the interlocking gear 152 so as to be rotatable about one side of the T- The other handle is interlocked through the interlocking gear 152 and rotated in the opposite direction. At this time, when the T-shaped foldable handle 150 is extended in the horizontal direction, it is caught by the lower end of the lower claw pipe 112 to restrict the rotation in the downward direction. As described above, by rotating one of the T-shaped folding knobs 150, the other knob is rotated in association with the rotation of the other knob, so that the folding and straightening operation of the knob can be performed easily and quickly.

When the T-shaped foldable handle 150 is folded in the direction of the lower hooking pipe 112, a handle receiving groove 141 is formed in the lower portion of the lower hooking pipe 112 for storing the folded T- The handle receiving groove 141 is formed at a depth corresponding to the folded T-shaped foldable handle 150 so that the T-shaped foldable handle 150 can be sufficiently housed in the longitudinal direction.

When the T-shaped foldable handle 150 is housed in the handle receiving groove 141 formed in the lower claw pipe 112, the T-shaped foldable handle 150 can be easily pulled out of the T- A handle protrusion 151 is formed at an upper portion of the T-shaped foldable handle 150, which is exposed to the outside of the handle receiving groove 141. The handle protrusion 151 may be formed in various shapes such as a triangle or a quadrangle. On both sides of the handle protrusion 151, a groove may be formed to facilitate the catching of the fire brigade.

The fire suppression claw 100 having the above-described structure is configured such that the upper claw pipe 111 is housed in the lower claw pipe 112 and is fixed through the length adjuster 130 when the fire suppression claw 100 is not used normally, So that storage can be easily performed. When the length of the fire suppression claw 100 is shortened, the fire fighting claw 100 is loaded on the fire truck, and the fire fighting cage is moved to the site or the fire brigade has the fire fighting claw 100 It is easy to store and move quickly even when entering the inside of the building.

The firefighting team dispatched to the fire site pulls the threaded connection between the bolt 131 and the nut 132 of the length adjuster 130 and pulls the upper claw pipe 111 from the lower claw pipe 112 to extend the length And the upper claw pipe 111 is fixedly coupled to the lower claw pipe 112 by screwing through the length adjuster 130 again. The fire brigade uses the lengthy fire suppression hooks (100) to perform fire suppression by processing objects that may interfere with window glass breakage, door lock failure, and other fire suppression at a fire scene.

On the other hand, the fire-fighting claw 100 is made of a metal material and has a relatively long length, which is heavy and can be a physical burden for a firefighter to use for a long time alone. In addition, in the case of heavy obstacles in the field of fire, there is a case where a fire brigade is forced to use one force. In this case, it is necessary to use one fire fighting hook (100) together with two fire brigades. In this case, the firefighting team rotates the T-shaped foldable handle 150 housed in the handle receiving groove 141 at the lower end of the lower claw pipe 112 downward to be horizontally rotated, and then folds the folded T-shaped handle 150 Two firefighters will be able to carry out fire suppression more effectively by using them.

As described above, the fire suppression claw 100 according to the present invention adjusts the length of the fire suppression claw 100 through the length adjuster 130 so that it can be stored or used. The two fire brigade cooperates with each other through the T-shaped foldable handle 150 formed on the upper surface of the main body 110 to use the fire suppression claw 100.

The fire suppression hook according to the present invention can be variously modified in order to perform the same or similar functions. The present invention is not limited to the above-mentioned embodiments, It will be understood that various modifications and alterations may be made within the spirit and scope of the appended claims and their equivalents.
