[0002] Fire hydrants for fire protection buildings refer to fire hydrants installed in buildings to extinguish fires in the event of a fire. These fire hydrants are located at water supply hydrants that provide fire-resistant water. Fire hoses are installed inside the hull to spray fire-resistant water to the location of the fire.

[0003] In addition to the typical indoor fire hydrants used for firefighting in buildings, the prior art documents also provide indoor fire hydrants for building fire protection to prevent casualties from falling debris during an earthquake, and to allow for requesting or informing rescue personnel even if the power supply is cut off.

[0004] Whether it is a fire or an earthquake, in order to minimize losses, it is necessary to escape from the building in the early stages of a fire or earthquake or when the fire or earthquake has subsided. However, traditional fire hydrants in buildings have the problem of not being able to facilitate escape.

[0057] The terms or words used in this statement and scope of protection shall not be interpreted in their usual or prior sense. Inventors must interpret them in accordance with the principle that the concept of use can be appropriately defined, to convey the meaning and concept that conforms to the technical idea of ​​the invention, and to best describe the invention.

[0058] Therefore, the embodiments described in this list and the configurations shown in the drawings are only one ideal embodiment of the present invention and do not represent all the technical ideas of the present invention. Therefore, it should be understood that various homogeneous and modified examples may exist to replace them in this application.

[0059] The following is a detailed description of the indoor fire hydrant for fire protection buildings as specified in this invention, with reference to the accompanying drawings.

[0060] like Figure 1 As shown, the indoor fire hydrant (1) for fire protection buildings according to the present invention includes a pipe fitting (100), an air intake component (200), and a ladder component (300).

[0061] The pipe fitting (100) is laterally rolled into a roll shape inside the upper part of the fire hydrant housing. After being released to the outside of the building, it deforms into an air rebound shape with the function of a slide as air is drawn in.

[0062] More specifically, the aforementioned fitting (100) includes a fitting (110) and a fitting winding module (120).

[0063] The tube (110) is wound in the tube winding module (120).

[0064] The winding tube (110) on the tube winding module (120) is released from the tube winding module (120) and expands as air is drawn in and contracts as air is expelled.

[0065] In other words, the aforementioned tube (110) is in a contracted state, such as Figure 2 As shown in Figure a, the fire is released from the indoor fire hydrant (1) of the fire-fighting building specified in this invention and comes into contact with the ground, and then as follows: Figure 2 As shown in b, the air drawn in by the air intake member (200) expands.

[0066] At this time, it is recommended to cut the pipe fitting (110) into different lengths according to the height of the building and wind it into the pipe fitting winding module (120).

[0067] In addition, the aforementioned pipe (110) is preferably made of non-combustible material to prevent it from being easily damaged by flames in the event of a fire.

[0068] The tube winding module (120) includes a winding housing (121), a guide plate (122), an outer gear (123), a support shaft (124), an inner cylindrical gear (125), a constraint spring (126), and a winding motor (127).

[0069] The inside of the winding shell (121) is hollow, forming a hollow space (s), and there is a perforation in the center, forming a perforation hole (h).

[0070] The hollow space (S) is connected to the air intake component (200) and can intake or exhaust air.

[0071] The winding housing (121) has a cut (121a) on its outer peripheral surface along its length on one side, which is connected to one end of the tube (110) so that the sucked air can be injected into the tube (110).

[0072] At this time, the cut (121a) and one end of the tube (110) are coated with TPU (Thermoplastic Polyurethane) resin, preferably by an air-tight zipper, but not limited to this, and can be joined by other sealable joining methods.

[0073] An inflation port (121b) is formed on one side of the winding housing (121) to obtain inflation from the suction member (200).

[0074] The air inlet (121b) is connected to the air intake component (200) after the pipe (110) is completely unwound from the pipe winding module (120).

[0075] The guide plate (122) is a right-angled disc formed on the outer peripheral surface of the winding housing (121), which can guide the tube (100) on the winding housing (121) to be wound without deviating to one side.

[0076] The outer gear (123) forms a gear on the outer surface of one side of the winding housing (121), so that one side of the winding housing (121) has the same structure as the pinion.

[0077] The support shaft (124) has a circular cross section and passes through the perforation (h) formed by the central perforation of the winding housing (121). Once fixed inside the indoor fire hydrant (1) of the fire-fighting building of the present invention, the other side is connected by the rotating shaft (R) and bearing (B) of the winding motor (127).

[0078] The bearing (B) connects the support shaft (124) to the rotating shaft (R) of the winding motor (127) to prevent the rotational force of the rotating shaft from being transmitted to the support shaft (124).

[0079] The inner cylindrical gear (125) is hollow inside, with one side open and the closed side forming a structural hole (125a) corresponding to the cross section of the rotating shaft (R).

[0080] The inner cylindrical gear (125) is an inner cylindrical surface that meshes with the outer cylindrical gear (123) inserted into the hollow interior, forming a structural gear corresponding to the outer cylindrical gear (123).

[0081] As described above, since the hole (125a) forms a polygonal structure corresponding to the cross section of the rotating shaft (R), the inner cylindrical gear (125) can receive the rotational force of the winding motor (127).

[0082] The constraint spring (126) is inserted into the rotating shaft of the winding motor (127) and is located between the inner cylindrical gear (125) and the body of the winding motor (127). Through expansion and contraction, the rotational force of the winding motor (127) is transmitted to or released from the winding housing (121).

[0083] Additionally, the inner cylindrical gear (125) as Figure 4 As shown in Figure a, a fixing and releasing hole (125b) is formed around the hole (125a), as follows: Figure 4 As shown in b, the constraint spring (126) is compressed on the body of the winding motor (127).

[0084] A fixing and releasing protrusion (127a) that can be inserted into the fixing and releasing hole (125b) is formed on the winding motor (127).

[0085] The fixing and releasing protrusion (127a) is a structure in which a ball is formed at the end of a cylindrical rod. After the ball is inserted into the fixing and releasing hole (125b), it is fixed by rotating at the required angle and released by rotating in the opposite direction. The principle of fixing and releasing is also applied to the fixing and releasing hole (125b).

[0086] Figure 5 a Figure 5 As shown in diagram a, in the aforementioned tubing winding module (120), when the tubing (110) is released, air in the tubing (110) is drawn in as the aforementioned suction member (200) operates, such as... Figure 5 As shown in b, the air bounces back, forming a slide structure.

[0087] Next, in order to wind the tube (110) onto the tube winding module (120), the suction member (200) is activated to exhaust air from the tube (110) and rotate the inner cylindrical gear (125) by a certain angle so that the fixing & releasing protrusion (127a) disengages from the fixing & releasing hole (125b). According to the expansion elastic force of the spring (126), the inner cylindrical gear (125) accepts the outer cylindrical gear (123).

[0088] The pipe (110) will also draw in and exhaust air during an actual fire due to the air intake component (200), but it will also draw in and exhaust air during training.

[0089] As the outer cylindrical gear (123) is received by the inner cylindrical gear (125), gear meshing occurs, and the rotational force of the winding motor (127) causes the winding housing (121) to accept the rotation of the support shaft (124) and wind up the tube (110).

[0090] The air intake component (200) includes an air intake module (210) and a control module (220). The air intake module (210) intakes or exhausts air on the pipe (110) according to the control module (220).

[0091] The control module (220) controls the controllable air intake module (210) and the winding motor (127), etc.

[0092] The ladder component (300) is equivalent to the door of the indoor fire hydrant of the fire-fighting building as specified in this invention, which can help to easily escape from windows at high heights.

[0093] like Figure 2 As shown, once the window is opened, with the injection of air, if an air bounce is installed like a slide, the escapee can ride the air bounce to escape to the ground.

[0094] At this point, with the window height high, the escapee, having installed the fittings (100), would spend a considerable amount of time climbing to the window height, and the escape might encounter great difficulties.

[0095] More specifically, the aforementioned survivors, such as Figure 6 As shown, the door of the indoor fire hydrant of the fire-fighting building specified in this invention is lifted upwards, so that the inserted hinge bolt is removed from the nut, thereby separating the door from the fire hydrant.

[0096] According to the present invention, the door-ladder component (300) separated from the indoor fire hydrant of the fire-fighting building is as follows: Figure 7 As shown.

[0097] like Figure 7 As shown, the ladder component (300) includes a frame (310), a scaffold (320), a scaffold pivot (330), a sprocket (340), a chain (350), a bidirectional motor (360), and a control button (370).

[0098] The frame (310) is hollow inside. On the right-angled frame with a certain thickness, in order to enable the scaffold (320) to rotate, a number of rectangular holes corresponding to the scaffold (320) are formed on the inner side.

[0099] The scaffolding (320) rotates within the four-cornered hall formed inside the frame (310) under the support of the scaffolding pivot (330).

[0100] The scaffold rotation shaft (330) is a rod with a circular or polygonal cross-section, which runs through the scaffold (320) along its length and can rotate on the frame (310) at both ends.

[0101] The sprocket (340) is coupled to both ends of the pedal rotation shaft (330) that runs through the plurality of pedals (320) and receives rotational power.

[0102] The chain (350) meshes with all the chain gears (340) of a section of the pedal rotation shaft (330) that runs through the plurality of pedals (320), and also with all the chain gears (340) of the striking end.

[0103] The bidirectional motor (360) is installed at the bottom of the ladder component (300) and transmits (generates) rotational power through a bidirectional rotating shaft.

[0104] The sprocket (340) is also formed at the end of the rotating shaft of the bidirectional motor (360), and the rotational force is transmitted to the sprockets (340) at both ends of the plurality of scaffold rotating shafts (330) that mesh with and are engaged with the chain (350) on the chain (350).

[0105] The aforementioned control button (370) is formed on a frame (310) in a position that the escapee can operate.

[0106] The bidirectional motor (360) is rotated according to the escapee's operation, and the scaffolding (320) is rotated parallel to the ground according to the inclination of the ladder component (300) on the wall. Figure 8 As shown.

[0107] In addition, the frame (310) has rubber anti-slip parts (311) in the parts that come into contact with the ground and the wall.

[0108] The above is attached Figure 1 The technical concept of the present invention has been described above, but this is merely an example illustrating the ideal embodiments of the invention, and not a limitation thereof. Furthermore, it is obvious to anyone with ordinary knowledge of the art that various modifications and imitations can be made without departing from the scope of the technical concept of the present invention.
