In describing the fire hydrant (F) having a hose reel according to the present invention, for the sake of convenience, a non-strict approximate direction reference is specified with reference to FIGS. 1 to 3.

In the hose reel (R) exposed by turning by the hinge member 10 when opening the door (H1) provided on the right side of the housing (H) in Figure 1,

The firefighter water hose 23 is determined to the side to be coupled to one side, the pivot panel 13 of the hinge member 10 is determined to the other side to be coupled.

First, as shown in Figures 1 to 3, the fire hydrant (F) having a hose reel according to the present invention is largely a housing (H), a hose reel (R) built in the housing, and a hose reel (in the housing) R) and a hinge member (10) to be pivotable for exposure or internalization of the hose reel, and a fire hose (20) wound on the hose reel (R).

The housing (H) is usually made of stainless steel, has a door (H1), and is usually installed in a buried manner or external exposure to the building wall.

The fire hose 20 is made of a tough material to prevent puncture or damage, and is connected to the raw water hose 23 embedded in the housing (H) is connected to the fireman water supply pipe embedded in the wall (or exposed). The raw water hose is provided with a valve 25 to open in the event of a fire and fire fighting work.

The hinge member 10 includes a fixed panel 11 mounted on the side wall of the housing H, and a pivot panel 13 coupled to the fixed panel panel through a pivot shaft 15. Hose reel (R) is coupled,

'Hose reel connected to the pivot panel of the hinge member' may be implemented in various ways,

In particular, as will be described later, since the relay member 60 is simply coupled to the central shaft member 30 irrespective of the fire water distribution space, it is possible to achieve both the rotational performance of the hose reel and the fire water leakage prevention function with a simple structure. Can be.

As can be seen in Figure 7, the hose reel (R) embedded in the housing (H) is exposed to the outside of the housing (H) by the hinge member 10 after opening the door (H1),

Since it is fixed to a certain distance from the side wall of the housing through the spacer 11A connected to the fixing panel 11,

The hose reel coupled to the pivot panel 13 of the hinge member 10 is exposed to the outside of the housing H around the pivot 15.

The degree of obstruction by the shaft coupling portion H1A of the door H1 is greatly reduced, so that it can be swung more than 90 degrees from the initial built-in position.

Because of this, when pulling the hose 20 in the case of fire and rotating the hose reel (R) to unwind the hose by pulling the hose in the direction of fire occurrence, it is convenient to choose the direction of running while pulling the hose, ,

In addition, if the hose is dragged into the space where the hose can be unwound according to the building situation, it also provides the advantage of wider choice of direction.

In addition to Figures 3 to 6, as can be seen in Figures 1 and 2,

The hose reel R that forms the core of the fire hydrant (F) having a hose reel according to the present invention is the central shaft member 30, the pivot member 40, the disk 50A (50B), the relay member ( 60).

The central shaft member 30 serves as a pivotal axis of the hose reel R, the exposed portion 31 to which the raw water hose 23 is largely coupled, and is connected to the exposed portion 31 at one side, and the drain hole is It is made of a built-in portion 33.

A male screw portion 31a (see FIG. 4) is formed at one end of the exposed portion 31 so as to be tightly coupled through a fastening nut 23A provided in the raw water hose 23, and the raw hose 23. ) Has an appropriate length so that the hose reel (R) is built into the housing (H) and there is no problem in the turning operation in the process of being exposed for fire fighting.

In addition, the built-in part 33 is connected to the exposed part 31 (particularly integrally connected) and the first contact part 33A which is inscribed to the pivot member 40, and the first contact part (in particular) Integrally connected) and a second indentation part 33C having the drain hole 33b formed therein, and a second contact part 33C connected to the indentation part (particularly integrally connected) and inscribed in the pivot member 40. .

The first close contact portion 33A has a locking flange 33a to limit the degree of coupling to the pivot member 40, and a packing ring 33p (see FIG. 6) is provided on an outer circumferential surface thereof so that the pivot member 40 is provided. ) And the second close contact portion 33C is also the same in that the packing ring (33p) is provided on the outer peripheral surface,

Each packing ring 33p is coated with a lubricant (less viscous) to maintain the watertightness of the remaining hose reel (R) components, including the pivot member 40 which rotates about the central shaft member 30. It is desirable that there is no problem in rotating at an appropriate speed while sufficiently supporting the load.

The concave portion 33B is located between two close portions 33A and 33C,

The diameter, especially the outer diameter, is relatively small

After the firefighting water supplied from the firefighting communication path 30A (see FIG. 4) leading from the exposed part 31 to the interior part 33 flows in through the drain hole 33b,

A firefighter communication space S (see FIG. 4) may be formed again between the concave indentation 33B and the pivot member 40.

The plurality of drain holes 33b are formed on the outer circumferential surface of the concave indentation 33B so that there is no problem in the flow rate of the fire water.

Meanwhile, a female screw part is formed at the center of the other end of the second close contact part 33C as a fastening part 33c for coupling the pivot panel 13 and the hose reel R of the hinge member 10.

Next, the pivot member 40 is in close contact with the interior portion 33 of the central shaft member 30, in particular, the two contact portions 33A, 33C, and tightly received, and both disks 50A and 50B at both ends. The engaging jaw 41A (41B) for coupling is formed.

The firefighter passing through the communication space (S) formed between the above-mentioned turning member 40 and the interior portion 33, in particular, the concave portion (33B) passes through the drain 43 of the outer peripheral surface,

The curved curved connection pipe (450) is screwed to the drain portion, so that when the fire hose 20 is wound on the hose reel (R), it can be wound in a circular shape from the beginning so that there is no problem of bending the fire hose. do.

Furthermore, the drain 43 is biased to one side of the pivot member 40, and as shown in FIG. 2, the first winding is configured such that the fire hose 20 is sequentially wound from one side of the hose reel R to the other side.

Fire hose (20) is also tightly coupled to the end of the curved connecting pipe 45 by a fastening nut 21 (see Figs. 1 and 2).

The two disks 50A and 50B to which the hollow 50a is fitted to the engaging jaws 41A and 41B at both ends of the pivot member 40 are coupled in a plurality (radially symmetrically about the central shaft member 30). Is firmly coupled by the tension member 51 of the) is tightly fixed,

The tension member 51 has a sleeve 51A at both ends thereof in contact with the inner surfaces of the disks 50A and 50B, and screwed to the sleeve 51A (threads are omitted for convenience in the cross-section of FIG. 5). It consists of the bolt 51B which fixes 50A) 50B.

The fire hose 20 is wound in the form of the innermost portion that is in contact with the sleeve 51A of the tension member substantially at the time of winding,

The curved connecting pipe 45 of the pivot member 40 is coupled in a form spanning the sleeve 51A.

The method of coupling the hose reel (R) to the pivot panel 13 of the hinge member 10 may be selected in various ways, but in the present invention, the impact or load of the components involved in the fireman's distribution passage may not occur. Adopted a way to combine in the form of

To this end, the relay member 60 is introduced in the present invention.

The relay member 60 includes an overlapping portion 61 embedded in the other side of the pivot member 40 and a mounting portion 63 exposed to the other side of the overlapping portion 61.

In addition, the engaging flange 61A is formed at the other end of one side overlapping portion 61 so as to limit the degree of insertion into the pivot member 40.

Fastening means for fixing the relay member 60 to the central shaft member 30, and again fixing the hose reel (R) to the pivot panel 13 of the hinge member 10 is one common bolt-type fastening means (61) is advantageous in terms of assembly, maintenance, production cost.

In addition, the central shaft member 30 of the hose reel R is fixed,

In order to allow only the two disks 50A and 50B fixed to the pivot member 40 and the latching jaws 41A and 41B at both ends of the pivot member 40 to pivot.

The fastening means 65 is coupled to the fastening part 33c of the second close part 33C of the built-in part 33 of the central shaft member 30,

As can be seen in Figures 3 and 6, the through-hole 63A formed in the center of the mounting portion 63, which is a non-circular shape, more specifically, an elliptical protrusion, is looser than the outer diameter of the fastening means 65,

While not in contact with the fastening means (65), in order to lose weight, the inside of the overlapping portion (61) has an empty space having an inner diameter larger than the through hole (63A),

The engaging flange 61A is formed so as to reduce friction as much as possible by forming a fine spaced portion 61B (see FIG. 4) without substantially contacting the other end of the pivot member 40.

According to the shape of the mounting portion 63, the shape of the pivot panel 13 is also non-circular, in particular, an elliptic shape (see FIG. 3),

A washer 65A is interposed between the pivot panel 13 and the bolt head serving as the fastening means 65.

As described above, the fire hydrant (F) according to the present invention and the components for the rotation of the hose reel (R) and

While the components for delivering firefighters from the raw water hose 23 to the fire hose 20 consist of only the central shaft member 30 and the pivot member 40,

There is no problem in supporting the load of the disks 50A and 50B and the fire hose 20, which occupy the main weight of the hose reel R and prevent the detachment of the wound hose.

The hinge member 10 and the hose reel R are fixed to the relay member 60 through only the bolt-type fastening means 65.

As the number of parts is drastically reduced, it secures ease of manufacture and cost competitiveness, and is easy to assemble and maintain.

There is no leakage problem in the distribution of firefighters, the hose 20 winding and unwinding can be made smoothly and at an appropriate speed.

First of all, since the hose reel R is coupled to the hinge member 10 through the relay member 60, the hose reel R is made independent of the central shaft member 30 or the pivot member 40 for the distribution of firefighters, and thus is significantly different from the conventional hose reel. Thereby, there is no risk that the leakage or leakage problems due to long use due to the hinge member 10 and the coupling portion.

In addition, since the hose reel R is almost symmetrically coupled to the symmetrical internal part 33 of the central shaft member 30 serving as a rotating shaft, the balance is maintained.

(This function is further enhanced by a symmetrical pivot member 40 that substantially receives the central axis member to act as a bush and the two disks are coupled at both ends.

(Regarding the degree of weight bias of the hose reel (R) in the situation that the fire hose 20 is wound around

The asymmetry problem caused by the drain 41 and the connector 45 of the pivot member 40 is a negligible situation,

The asymmetry problem caused by the exposed portion 31 in the central shaft member 30 is the same, and furthermore, the load of the exposed portion 31 is canceled to some extent by the load of the second contact portion 33C and the relay member 60. It is possible))

There is no fear that the unbalanced load will be applied to the central shaft member, so even after repeated use, a tolerance such as uneven wear does not occur, and thus problems such as the hose reel rotation interruption or blocking are not generated.

In the above description, the materials and dimensions of fire hydrants, hose reels, hoses, and the like, and general known techniques related to the desired friction force when turning the hose reel for unwinding the fire hose are omitted, but those skilled in the art can easily infer, infer, and reproduce them. can do.

In the above description of the present invention, the fire hydrant having a specific shape and structure has been described with reference to the accompanying drawings, but the present invention can be variously modified, changed, and replaced by those skilled in the art, and such modifications, changes, and substitutions may be made by the present invention. It should be interpreted as falling within the protection scope of.
