Description

  The present invention relates to a fire hydrant, a fire hydrant valve, and a fire hydrant apparatus including the same.

  Conventionally, there is a fire hydrant device. In the fire hydrant device, a fire hose with a nozzle connected to the tip side and a fire hydrant valve provided between the fire hose and the water source for fire extinguishing are housed in the housing, and when a fire breaks out In addition, the fire hose valve is opened by pulling out the fire hose and turning the handle part of the fire hydrant valve, and fire extinguishing activities can be performed by supplying fire water to the fire hose. .

  Fire hydrant devices are usually installed for the purpose of initial fire extinguishing before the fire brigade reaches the fire site. Some fire hose possessed by the fire brigade can be connected. There is a fire hydrant (hereinafter referred to as a hydrant) provided in a housing (see, for example, Patent Document 1). Since such a water hydrant has a larger pipe diameter than a fire hydrant, it has a larger handle part than a fire hydrant valve. By turning the handle part and opening the water hydrant, Fire water can be supplied to the hose.

  However, such a fire hydrant valve and the faucet handle are usually substantially circular, and it is necessary to turn the handle more than once to open and close the hydrant valve and the water hydrant. Yes. Such a handle portion particularly requires the greatest force when starting to rotate, but the force required at this time can be reduced as the diameter of the handle portion is increased. For this reason, it is desirable that the diameter of the handle portion is larger from the viewpoint of easy turning in the early stage of turning the handle portion. In particular, in the faucet, the pipe diameter is large, and accordingly, a larger force is required when starting to turn the handle part. Therefore, the diameter of the handle part is desirably as large as possible.

  On the other hand, from the middle to the end of turning the handle part, those who are going to open and close the fire hydrant valve or water hydrant need to extend their arms when turning the handle part, but the larger the handle diameter, the more It is necessary to extend the arm to the back of the fire hydrant device. Since the space in the housing is not so large, it cannot be said that the handle portion having a large diameter is always easy to turn from the middle stage to the end stage where the handle part is turned.

  Then, this invention solves this contradiction, and even if it provides in the housing | casing of a fire hydrant apparatus, it aims at providing the water tap and the fire hydrant valve which can be opened and closed more easily.

  The present invention is a water faucet provided between a water intake, a water supply port for supplying water supplied into the water tap through the water intake, and the water intake and the water supply port. A valve portion provided to be able to open and close the water flow path from the water intake port to the water supply port, and a handle portion for opening and closing the valve portion. A fire hydrant having a radius changing means and capable of reversibly changing its turning radius.

  Further, the present invention is a fire hydrant valve, comprising a water intake, a water supply port for supplying water supplied into the fire hydrant valve through the water intake, and between the water intake and the water supply port A valve portion provided to be capable of opening and closing the water flow path from the water intake to the water supply port, and a handle portion for opening and closing the valve portion, the handle portion comprising: It is a fire hydrant valve which has a turning radius change means and is provided so that the turning radius can be changed reversibly.

  Further, the present invention includes at least a housing and the fire hydrant or the fire hydrant valve, and the fire hydrant or the fire hydrant valve is provided in the housing. Device.

  In the present invention, the turning radius changing means can be an expansion / contraction means or a bending means. In the present invention, the handle portion may include a handle auxiliary portion provided so as to be movable in the coaxial direction with the handle portion by the expansion and contraction means. According to the present invention, the handle portion has a base portion and a grip portion provided so as to extend substantially perpendicularly from the base portion, and the grip portion is rotated about its central axis. It can be attached to the base as possible. In the present invention, the handle portion may be provided with an extension portion extending in the same direction as the handle portion, and the extension portion may be provided detachably from the handle portion. is there.

  In the present invention, since the handle portion is provided so as to be extendable or bendable, the turning radius of the handle portion is increased in the early stage of turning the handle portion that requires a larger force to turn the handle portion. In addition, it is possible to reduce the turning radius from the middle to the end of turning the handle, which does not require much force compared to the beginning to turn the handle. Therefore, even if it is provided in the housing of the fire hydrant device, it is possible to provide a water hydrant and a fire hydrant valve that can be easily opened and closed.

In addition, the nozzle 11a is detachably attached to the nozzle holder 12 at all times.

  The faucet 3 is installed in the housing 2 located inside the faucet door 8. As the basic structure of the water tap 3, a known structure (for example, see Japanese Patent Application Laid-Open No. 2001-161849) can be adopted. For example, fire-fighting water connected to a pipe (not shown) from a fire-fighting water source A supply pipe 16 (hereinafter also referred to as supply pipe 16), a main body portion 18 having a water supply port 17 provided so that a fire hose (not shown) owned by a fire brigade can be connected, and a valve portion 19 Have. The supply pipe 16 is provided with a water intake 16a for supplying fire-extinguishing water into the water tap 3 from a pipe from the fire-extinguishing water source. In the present embodiment, a branch pipe 20 is connected to the supply pipe 16, and the branch pipe 20 is connected to the fire hydrant valve 15.

The valve unit 19 is provided so as to always close the flow path of the water for fire extinguishing from the supply pipe 16 to the water supply port 17 and to open the flow path during fire extinguishing activity, that is, to open and close the flow path. A shaft portion 19a screwed into a screw hole penetrating the main body portion 18 extends, and a valve body (not shown) is provided at one end of the shaft portion 19a so as to close the flow path. Z). A handle portion 21 for turning the shaft portion 19a to open and close the valve portion 19 is attached to the other end of the shaft portion 19a. The handle portion 21 can reversibly change its turning radius from the turning radius R ₁ to the turning radius R ₂ , and has turning radius changing means for that purpose.

  In the present embodiment, a handle portion 21A is employed as the handle portion 21. The handle portion 21A has a substantially rod shape and includes a mounting portion 22 and a handle portion main body 23A extending from the mounting portion 22. doing. The attachment portion 22 is provided with a hole (not shown) in the center of which the shaft portion 19a can be inserted, and the handle portion 21A is fixed to the shaft portion 19a through the hole portion. Installed.

  The handle portion main body 23A is a portion that is gripped when the faucet 3 is opened and closed, and has a sliding portion 24 and a handle auxiliary portion 25A as an expansion / contraction means that is an example of the turning radius changing means. Yes. The sliding portion 24 extends from the mounting portion 22 in the direction coaxial with the axial direction A1 of the handle portion 21A, and is provided in a substantially cylindrical shape. When opening and closing the plug 3, it is provided with a length that can be held by a person who opens and closes it.

  The handle auxiliary portion 25A is provided so as to be slidable along the inner surface of the sliding portion 24. The handle auxiliary portion 25A is provided on the proximal end side of the handle auxiliary portion 25A so as to be able to engage with the latching portion 26. It has a retaining portion 27 for preventing further separation. That is, the handle auxiliary portion 25A is provided so as to be movable in a direction coaxial with the axial direction A1 of the handle portion 21A from the position indicated by the alternate long and short dash line in FIG.

  Thereby, the handle portion 21A can be expanded and contracted. That is, the handle portion 21A can easily change between a state where the handle auxiliary portion 25A is extended and a state where the handle auxiliary portion 25A is reduced. Further, the handle auxiliary portion 25A is provided so that it can be gripped at least when the handle portion 21A is most extended.

  When opening the water tap 3, (1) First, the water tap door 8 is opened, and the front side of the water tap 3 is opened. (2) A fire hose is attached to the water supply port 17. (3) The handle auxiliary portion 25A of the handle portion 21A is moved coaxially with the axial direction A1 to extend the handle portion 21A (see FIG. 2A). (4) Grasp the handle auxiliary portion 25A and turn the handle portion 21A in the opening direction A2.

Thereafter, by turning the handle portion 21A while the handle auxiliary portion 25A is contracted, the valve portion 19 that closes the flow passage is opened and the flow passage is opened, so that fire fighting water is supplied to the fire hose. Supplied.

That is, in the faucet 3, if the space S on the near side of the faucet 3 can be secured, the handle portion main body 23A is moved at the early stage of the turning of the handle portion 21A that would require the most force. by extension, it is possible to turn the handle portion 21A while ensuring longer turning radius R ₁ of the handle portion 21A, the force required to turn the handle portion 21A is made can be reduced . Then, to turn the handle portion 21A, because it does not require the natural extent force as compared to the early, the handle main body 23A condensation poured, short in turning radius R ₂ than the turning radius R _1, the handle portion 21A can be turned, and a person who opens and closes the water tap 3 can turn the handle portion 21A without extending the arm so much.

Therefore, the water faucet 3 can be opened and closed more easily than the conventional water faucet even if it is provided in the housing 2.

  Further, as in the present embodiment, the following can be cited as a secondary effect of using the handle portion 21A for opening and closing the water tap 3. The fire hydrant device is required to have a thin casing because of problems such as installation space. The thinner the casing of the fire hydrant device, the narrower the depth of the space in the casing, and thus the narrower the gap between the handle portion and the back plate of the casing. In the case of a substantially circular handle part such as a conventional fire hydrant device, if there is no gap between the handle part and the back plate, the back plate becomes a hindrance when operating the handle, and the hydrant can be opened and closed. There is a possibility of trouble, and because the handle part is larger than the width of the main body part, the handle part cannot be stored. It was difficult.

In the fire hydrant device 1, even if the casing 2 is thinned and the gap G between the back plate 4 a of the casing 2 and the handle portion 21 </ b> A becomes narrow, a space S on the front side of the water hydrant 3 is secured. If possible, the turning radius R ₁ at the beginning of the turning of the most powerful handle portion 21A can be secured larger, and thereafter, the handle portion 21A is contracted to turn the turning radius R _1. by turning the handle portion 21A with a shorter turning radius R ₂ a, gap G can be turned easily handle portion 21A servant and was narrow. Therefore, by adopting the water tap 3, it is possible to achieve both the thinning of the housing 2 and the ease of opening and closing the water tap 3.

  A second embodiment of the present invention will be described with reference to FIG. The difference between the present embodiment and the first embodiment is that a handle portion 21B is adopted as the handle portion 21. Other configurations indicated by the same reference numerals as those in the first embodiment are the same as those in the first embodiment, and thus description thereof is omitted.

  The handle portion 21 </ b> B has a substantially rod shape, and includes an attachment portion 22 and a handle portion main body 23 </ b> B extending from the attachment portion 22. The handle portion main body 23B has a base 28B and a gripping portion 30B rotatably attached to the base 28B via a hinge portion 29 as bending means which is an example of the turning radius changing means. The base portion 28B is provided so as to extend from the attachment portion 22 in a direction coaxial with the axial direction A1 of the handle portion 21B.

  Further, the hinge portion 29 is provided so that the grip portion 30B can be rotated in the rotation direction A3 to the position shown by the alternate long and short dash line in FIG. 3 with respect to the base portion 28B. 21B can be bent so that the gripping portion 30B extends substantially vertically from the base portion 28B. That is, the handle portion 21B extends the grip portion 30B in a state coaxial with the axial direction A1, and extends the grip portion 30B in a direction orthogonal to the axial direction A1 (vertical direction in the present embodiment). You can easily change the status. Note that the rotation angle of the handle portion 21B can be appropriately selected as necessary.

In the present embodiment, instead of the step (3), the gripping portion 30B is extended in the same direction as the axial direction A1, so that the turning radius R of the handle portion 21B can be increased during the step (4). ₁ can be secured for a longer time, and instead of the step (5), the grip portion 30B is rotated in the rotation direction A3, and the grip portion 30B is extended in the vertical direction. during step), the rotation radius R ₂ of the handle portion 21B has become possible to shorter than turning radius R _1, it is possible to achieve the same effect as the first embodiment. And in this embodiment, since the holding | grip part 30B is extended in the direction orthogonal to the axial direction A1, compared with the sliding part 24 of 1st Embodiment, the length can be lengthened. Therefore, it is easier to open and close the water tap 3.
