【発明の属する技術分野】
本発明は、消雪ノズルに関するものである。
【０００２】
【従来の技術及び発明が解決しようとする課題】
地面に埋設して消雪を行う消雪ノズルとしては、例えば、ノズル本体の先端開口部に、環部材を嵌入し得る嵌合凹部を設け、この環部材には前記通水路と連通して前記水の噴出方向及び噴出角度を規定する散水路が形成され、この環部材には、弁体が挿通される挿通孔を形成し、この挿通孔には前記弁体の頭部の係止部が係止する係止段部を設け、この弁体には前記ノズル本体の通水路に設けられた螺合部と螺合する螺子部を設け、弁体を前記挿通孔に挿通し、前記螺子部を螺合部と螺合することで前記ノズル本体に環部材が押さえ込み状態に止着されるように構成し、弁体に設けた弁機構により散水量を調節して環部材の散水路より散水するものがある。
【０００３】
具体的には、前記通水路を前記環部材に穿設した構造や、この環部材と弁体との間若しくは環部材と嵌合凹部との間に前記通水路を設けた構造等、種々の構造がある。
【０００４】
一般的に、消雪ノズルは自動車が走行する道路に埋設されることが多く、この自動車が消雪ノズル上を走行することで前記環部材が回動したり、直接上面を走行しなくても前記自動車の走行によって伝わる振動により前記環部材ががたついて回動したりすることで、この環部材を押さえ込み止着する弁体を緩めることがあり、場合によってはこの環部材が外れてしまうおそれがある。
【０００５】
そこで、従来は、特許第３１５６９１４号公報に開示されるように、前記ノズル本体の嵌合凹部と環部材とに突起と窪み部とから成る位置決め部を設け、この位置決め部によって前記環部材を位置決めすることで前記自動車等の振動による環部材の回動を阻止していた。
【０００６】
ところで、消雪ノズルを使用する際、例えば前記散水路がノズル本体の上面に９０度間隔で形成して四方に水を噴出させて消雪を行うように設定されているとすると、前記散水路同志の間には水が届きにくく、雪が残ってしまう部分が生じるため（例えば、双方から４５度の位置等）、前記水の噴出方向を変更したい場合がある。
【０００７】
しかし、従来の消雪ノズルの場合、前記嵌合凹部に嵌入したままでは環部材を回動させることができないため、水の噴出方向が異なる環部材等に一々交換しなければ、前記水の噴出方向を変更することができず、そのため、噴出方向の夫々異なる数種類の環部材を用意する必要があり、煩わしさは避けられない。
【０００８】
本発明は、上述のような現状に鑑み、弁体を軸として回動するこの環部材とノズル本体とに回り止め係止部を夫々設け、前記環部材に設けた回り止め係止部が前記ノズル本体に設けた回り止め係止部に突き当たり係止することで前記環部材の過回動を阻止し得るように構成し、前記環部材は、前記嵌合凹部に嵌入された状態で前記環部材に設けた回り止め係止部が前記ノズル本体に設けた回り止め係止部に突き当たり係止するまでの所定範囲を自在に回動させて前記水の噴出方向を変更し得るように構成することで、一つの前記環部材を回動させて嵌合凹部に嵌入することで自在に水の噴出方向を設定できるだけでなく、振動による前記環部材の過回動を阻止してこの過回動により前記弁体が緩んでしまうことを阻止でき、更に、この環部材を嵌合凹部から外す必要なくこの嵌合凹部に嵌入した状態で回動させて前記水の噴出方向を調整することもできる極めて容易且つコスト安に水の噴出方向を変更できる極めて実用性に秀れた消雪ノズルを提供するものである。
【０００９】
【課題を解決するための手段】
添付図面を参照して本発明の要旨を説明する。
【００１０】
ノズル本体３の先端開口部１に、環部材６を嵌入し得る嵌合凹部７を設け、この環部材６は前記ノズル本体３の通水路４内壁から突設された嵌入支承部１０により支承されて前記嵌合凹部７と嵌合し、この環部材６には前記通水路４と連通して水の噴出方向及び噴出角度を規定する散水路２が形成され、この環部材６には、弁体９が挿通される挿通孔５を形成し、この挿通孔５には前記弁体９の頭部の係止部９ａが係止する係止段部５ａを設け、この弁体９には前記ノズル本体３の通水路４に設けられた螺合部８と螺合する螺子部９ｂを設け、弁体９を前記挿通孔５に挿通し、前記螺子部９ｂを螺合部８と螺合することで前記ノズル本体３に環部材６が押さえ込み状態に止着されるように構成し、前記弁体９を軸として回動するこの環部材６と前記ノズル本体３とに回り止め係止部６ａ，３ａを夫々設け、前記環部材６に設けた回り止め係止部６ａが前記ノズル本体３に設けた回り止め係止部３ａに突き当たり係止することで前記環部材６の過回動を阻止し得るように構成し、前記環部材６は、前記嵌合凹部７に嵌入された状態で前記環部材６に設けた回り止め係止部６ａが前記ノズル本体３に設けた回り止め係止部３ａに突き当たり係止するまでの所定範囲を自在に回動させて前記水の噴出方向を変更し得るように構成し、前記弁体９に設けた弁機構により散水量を調節して環部材６の散水路２より散水することを特徴とする消雪ノズルに係るものである。
【００１１】
また、前記環部材６に設けた回り止め係止部６ａをこの環部材６にして前記ノズル本体３基端側に設け、前記ノズル本体３に設けた回り止め係止部３ａをこのノズル本体３の通水路４内壁にして嵌入支承部１０と螺合部８との間に設けられた設置面１１に設けたことを特徴とする請求項１に記載の消雪ノズルに係るものである。
【００１２】
また、前記環部材６に設けた回り止め係止部６ａと前記ノズル本体３に設けた回り止め係止部３ａのいずれか一方を凸部とし、他方をこの凸部と嵌合する凹部とし、この凹部を前記凸部が所定範囲を自在に回動し得る間隔に設定したことを特徴とする請求項１，２のいずれか１項に記載の消雪ノズルに係るものである。
【００１３】
また、前記環部材６に設けた回り止め係止部６ａと前記ノズル本体３に設けた回り止め係止部３ａの双方を凸部とし、前記環部材６がこの凸部同志が突き当たり係止するまでの所定範囲を自在に回動し得るように設定したことを特徴とする請求項１，２のいずれか１項に記載の消雪ノズルに係るものである。
【００１４】
また、前記環部材６に設けた回り止め係止部６ａ若しくは前記ノズル本体３に設けた回り止め係止部３ａを複数設けたことを特徴とする請求項１〜４のいずれか１項に記載の消雪ノズルに係るものである。
【００１５】
【発明の実施の形態】
ノズル本体３を地面に埋設し、弁機構により散水量を調節した水を散水路２から噴出して消雪を行う。
【００１６】
この際、例えばこのノズル本体３の上面を自動車が走行したり、近傍を走行する自動車から伝わる振動によって環部材６が回動したとしても、前記環部材６に設けた回り止め係止部６ａがノズル本体３に設けた回り止め係止部３ａに突き当たり係止することで過回動が阻止されることになる。
【００１７】
即ち、環部材６の回動は無制限でなく、前記環部材６に設けた回り止め係止部６ａが前記ノズル本体３に設けた回り止め係止部３ａに突き当たり係止するまでの所定範囲に限られるから、この環部材６の回動により軸となる弁体９の螺子部９ｂが緩んで外れてしまうことを阻止できる。
【００１８】
しかも、例えば散水路２が９０度間隔で設けられ、この散水路２同志の間に水が届きにくい部分があっても、本発明は、前記嵌合凹部７に環部材６を位置決めする構成でないから、所望の水の噴出方向に設定した上で前記嵌合凹部７に嵌入し、弁体９により押さえ込み止着することができ、水の噴出方向が異なる数種類の環部材６を用意する必要なく、一つの環部材６を回動することで所望の水の噴出方向に設定することができる。
【００１９】
その上、上述のように前記環部材６の回動が環部材６に設けた回り止め係止部６ａが前記ノズル本体３に設けた回り止め係止部３ａに突き当たり係止するまでの所定範囲に限られるということは、いいかえれば、この所定範囲内であれば前記環部材６を自在に回動し得るということであり、例えば前記弁体９を緩めてこの環部材６を回動することでこの環部材６を前記嵌合凹部７に嵌入した状態のままで外す必要なく前記水の噴出方向を微調整できることになる。
【００２０】
また、例えば、前記環部材６に設けた回り止め係止部６ａと前記ノズル本体３に設けた回り止め係止部３ａの双方を凸部とし、前記環部材６がこの凸部同志が突き当たり係止するまでの所定範囲を自在に回動し得るように設定した場合、前記環部材６に設けた回り止め係止部６ａを略３６０度回動させるように設定することもでき、この場合には、前記環部材６を嵌合凹部７に嵌入する前に回動させて前記水の噴出方向を設定する必要なく、前記嵌合凹部７に前記環部材６を嵌入した状態でこの環部材６を回動させて前記水の噴出方向を自在に設定できることになる。
【００２１】
また、例えば、前記環部材６に設けた回り止め係止部６ａと前記ノズル本体３に設けた回り止め係止部３ａのいずれか一方を凸部とし、他方をこの凸部と嵌合する凹部とし、この凹部を前記凸部が所定範囲を自在に回動し得る間隔に設定した場合、前記凹部を凸部が回動する範囲を極めて狭く設定することで、前記凸部がほとんど回動しないように設定することもでき、この場合には、前記自動車等による振動による環部材６の回動を阻止できることになる。
【００２２】
従って、本発明は、一つの環部材を回動させて嵌合凹部に嵌入することで自在に水の噴出方向を設定できるだけでなく、振動による前記環部材の過回動を阻止してこの過回動により前記弁体が緩んでしまうことを阻止でき、更に、この環部材を嵌合凹部から外す必要なくこの嵌合凹部に嵌入した状態で回動させて前記水の噴出方向を調整することもできる極めて容易且つコスト安に水の噴出方向を変更できる極めて実用性に秀れた消雪ノズルを提供できることとなる。

本発明の具体的な実施例について図面に基づいて説明する。
【００２４】
本実施例は、ノズル本体３の先端開口部１に、環部材６を嵌入し得る嵌合凹部７を設け、この環部材６は前記ノズル本体３の通水路４内壁から突設された嵌入支承部１０により支承されて前記嵌合凹部７と嵌合し、この環部材６には前記通水路４と連通して水の噴出方向及び噴出角度を規定する散水路２が形成され、この環部材６には、弁体９が挿通される挿通孔５を形成し、この挿通孔５には前記弁体９の頭部の係止部９ａが係止する係止段部５ａを設け、この弁体９には前記ノズル本体３の通水路４に設けられた螺合部８と螺合する螺子部９ｂを設け、弁体９を前記挿通孔５に挿通し、前記螺子部９ｂを螺合部８と螺合することで前記ノズル本体３に環部材６が押さえ込み状態に止着されるように構成し、前記弁体９を軸として回動するこの環部材６と前記ノズル本体３とに回り止め係止部６ａ，３ａを夫々設け、前記環部材６に設けた回り止め係止部６ａが前記ノズル本体３に設けた回り止め係止部３ａに突き当たり係止することで前記環部材６の過回動を阻止し得るように構成し、前記環部材６は、前記嵌合凹部７に嵌入された状態で前記環部材６に設けた回り止め係止部６ａが前記ノズル本体３に設けた回り止め係止部３ａに突き当たり係止するまでの所定範囲を自在に回動させて前記水の噴出方向を変更し得るように構成し、前記弁体９に設けた弁機構により散水量を調節して環部材６に穿設した孔から成る散水路２より散水するものである。
【００２５】
具体的には、前記環部材６に設けた回り止め係止部６ａをこの環部材６にして前記ノズル本体３基端側に突出状態に設け、前記ノズル本体３に設けた回り止め係止部３ａをこのノズル本体３の通水路４内壁にして嵌入支承部１０と螺合部８との間に設けられた設置面１１に前記環部材６側に突出状態に設けたものである。
【００２６】
更に具体的に説明すると、前記環部材６に設けた回り止め係止部６ａ及び前記ノズル本体３に設けた回り止め係止部３ａを夫々凸部とし、この凸部同志が突き当たり係止するまで前記環部材６を回動自在に設定したものである。
【００２７】
また、本実施例は図１に図示したように、前記ノズル本体３の上部を径大部１３とし、この径大部１３に前記嵌合凹部７を形成し、この嵌合凹部７の下方を前記径大部１３より径小として前記嵌入支承部１０に設定し、このノズル本体３の略中央部に前記螺合部８を形成したものである。
【００２８】
更に、本実施例は、この嵌入支承部１０と螺合部８との略中間位置に水平方向に突出する径小部１４を形成し、前記径大部１３からこの径小部１４の手前までを、なだらかに下り傾斜する傾斜面１６に設定している。

【００３１】
また、第一実施例の内、図３，４に図示したものは、前記ノズル本体３に設けた回り止め係止部３ａを対向する位置に一対設け、前記環部材６に設けた回り止め係止部６ａを一つ設けた構成である。
【００３２】
即ち、前記環部材６が略１８０度自由に回動できるように設定して略自由に水の噴出方向を変更することができるように構成したが、前記環部材６に設けた回り止め係止部６ａと前記ノズル本体３に設けた回り止め係止部６ａとを一つずつ設けた構成としても良く、この場合には略３６０度自由に前記環部材６を回動できることになり、より一層自由に前記水の噴出方向を変更できることになる。
【００３３】
一方、図５，６に図示したものは、前記ノズル本体３に設けた回り止め係止部３ａを対向する位置に設けた一対と、この一対と斜設状態に設けた一つを加え計三つを設け、前記環部材６に設けた回り止め係止部６ａを前記ノズル本体３に設けた回り止め係止部３ａの幅と略同じ間隔に二つ設けた構成である。

即ち、前記環部材６に設けた回り止め係止部６ａで前記ノズル本体３に設けた回り止め係止部３ａを挾持するように前記環部材６を嵌合凹部７に嵌入すると、この環部材６の回動は略阻止されることになり、逆に前記ノズル本体３に設けた回り止め係止部３ａ間に前記環部材６に設けた二つの回り止め係止部６ａを配設するように前記環部材６を嵌合凹部７に嵌入すると、この環部材６は所定間隔だけ自由に回動できるように設定している。
【００３５】
従って、第一実施例は、一つの環部材を回動して嵌合凹部に嵌入することで自在に水の噴出方向を設定できるだけでなく、振動による前記環部材の過回動を阻止してこの過回動により前記弁体が緩んでしまうことを阻止でき、更に、この環部材を嵌合凹部から外す必要なくこの嵌合凹部に嵌入した状態で回動させて前記水の噴出方向を調整することもできる極めて容易且つコスト安に水の噴出方向を変更できる極めて実用性に秀れたものとなる。
【００３６】

【００３７】
また、第二実施例においては、前記王冠部材１２に設けた回り止め係止部３ａ同志の間隔を前記環部材６に設けた回り止め係止部６ａの幅よりやや広く設定して前記環部材６を所定範囲で自在に回動できるように設定している。
【００３８】
また、前記ノズル本体３に設けた回り止め係止部３ａ同志の間隔を前記環部材６に設けた回り止め係止部６ａの幅と略同じ間隔に設定しても良く、この場合には前記環部材６の回動を略阻止し得る構成となり、しかも、前記ノズル本体３に設けた回り止め係止部３ａは前記環部材６の回動方向に多数設けた構成であるから、この環部材６を前記嵌合凹部７から一旦外して回動して以前と異なるノズル本体３に設けた回り止め係止部３ａ間に嵌入することで前記水の噴出方向を自在に設定できることになる。
【００３９】
その余は第一実施例と同様である。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a snow removal nozzle.
[0002]
Problems to be solved by the prior art and the invention
As a snow removal nozzle buried in the ground to perform snow removal, for example, a fitting concave portion into which a ring member can be fitted is provided at the tip end opening of the nozzle body, and the ring member communicates with the water passage to communicate with the water passage. A water spouting channel that defines the direction and angle of water ejection is formed, and an insertion hole through which the valve element is inserted is formed in this ring member, and a locking portion of the head of the valve element is formed in this insertion hole. A locking step portion for locking is provided, a screw portion for screwing with a screw portion provided in a water passage of the nozzle body is provided on the valve body, and a valve body is inserted through the insertion hole, and the screw portion is The ring member is fixed to the nozzle body in a pressed state by screwing with the screw portion, and the amount of water is adjusted by a valve mechanism provided on the valve body to spray water from the water passage of the ring member. There is something to do.
[0003]
Specifically, there are various structures such as a structure in which the water passage is perforated in the ring member, a structure in which the water passage is provided between the ring member and the valve body, or between the ring member and the fitting recess. There is a structure.
[0004]
Generally, a snow removal nozzle is often buried in a road on which a car travels, and when the vehicle runs on the snow removal nozzle, the ring member rotates or does not run directly on the upper surface. When the ring member rattles and rotates due to the vibration transmitted by the traveling of the automobile, the valve body that presses down and fixes the ring member may be loosened, and in some cases, the ring member may come off. There is.
[0005]
Therefore, conventionally, as disclosed in Japanese Patent No. 3156914, a positioning portion composed of a projection and a concave portion is provided in a fitting concave portion and a ring member of the nozzle body, and the positioning member positions the ring member. By doing so, the rotation of the ring member due to the vibration of the automobile or the like is prevented.
[0006]
By the way, when the snow spray nozzle is used, for example, assuming that the water sprinkling channel is formed on the upper surface of the nozzle body at intervals of 90 degrees and is set so as to blow out water in all directions to perform snow melting, Since it is difficult for water to reach between competitors and there is a portion where snow remains (for example, a position at 45 degrees from both sides), there are cases where it is desired to change the direction of the jet of the water.
[0007]
However, in the case of the conventional snow removal nozzle, since the ring member cannot be rotated while being fitted in the fitting concave portion, the water spouting must be performed unless the water member is exchanged with a ring member having a different jetting direction. Since the direction cannot be changed, it is necessary to prepare several types of ring members, each of which has a different ejection direction, and it is unavoidable to be troublesome.
[0008]
In view of the above-mentioned current situation, the present invention provides a detent locking portion on each of the ring member and the nozzle body that rotates around a valve body, and the detent locking portion provided on the ring member is provided with the detent locking portion. The ring member is configured to be able to prevent excessive rotation by abutting against and locking against a detent locking portion provided on the nozzle body. It is configured such that the rotation direction of the water can be changed by freely rotating a predetermined range until the detent locking portion provided on the member abuts and locks on the detent locking portion provided on the nozzle body. By rotating one of the ring members and fitting it into the fitting recess, not only the water jetting direction can be set freely, but also excessive rotation of the ring member due to vibration can be prevented, Can prevent the valve body from being loosened, and furthermore, this ring member The spouting direction of the water can be adjusted by rotating the spout in a state in which the spouting water does not need to be removed from the mating recess. The spouting direction of the water can be changed very easily and at a low cost. It is intended to provide a snow melting nozzle.
[0009]
[Means for Solving the Problems]
The gist of the present invention will be described with reference to the accompanying drawings.
[0010]
A fitting recess 7 into which the ring member 6 can be fitted is provided in the distal end opening 1 of the nozzle body 3, and the ring member 6 is supported by a fitting support portion 10 protruding from the inner wall of the water passage 4 of the nozzle body 3. In this ring member 6, a water passage 2 is formed in the ring member 6 which communicates with the water passage 4 and regulates the direction and angle at which water is jetted out.

BEST MODE FOR CARRYING OUT THE INVENTION
The nozzle body 3 is buried in the ground, and water whose amount of water is adjusted by a valve mechanism is blown out from the water spray channel 2 to perform snow removal.
[0016]
At this time, for example, even if the vehicle runs on the upper surface of the nozzle body 3 or the ring member 6 is rotated by vibration transmitted from a vehicle running in the vicinity, the rotation preventing locking portion 6a provided on the ring member 6 is not rotated. Excessive rotation is prevented by abutting against and locking against the detent locking portion 3a provided on the nozzle body 3.
[0017]
That is, the rotation of the ring member 6 is not limited, and is limited to a predetermined range until the detent locking portion 6a provided on the ring member 6 abuts and locks the detent locking portion 3a provided on the nozzle body 3. Since the ring member 6 is limited, it is possible to prevent the screw portion 9b of the valve body 9 serving as a shaft from loosening and coming off due to the rotation of the ring member 6.
[0018]
In addition, for example, even if the water sprinkling channels 2 are provided at intervals of 90 degrees and there is a portion where water does not easily reach between the water sprinkling channels 2, the present invention does not have a configuration in which the ring member 6 is positioned in the fitting concave portion 7.

By rotating one ring member 6, the desired water jetting direction can be set.
[0019]
Further, as described above, a predetermined range until the rotation of the ring member 6 abuts and locks the detent locking portion 6a provided on the ring member 6 against the detent locking portion 3a provided on the nozzle body 3. In other words, the ring member 6 can be freely rotated within the predetermined range, for example, by loosening the valve body 9 and rotating the ring member 6. Thus, it is possible to finely adjust the jetting direction of the water without having to remove the ring member 6 while keeping the ring member 6 fitted in the fitting concave portion 7.
[0020]
Further, for example, both the detent locking portion 6a provided on the ring member 6 and the detent locking portion 3a provided on the nozzle body 3 are formed as projections, and the ring member 6 is brought into contact with the projections. In the case where the predetermined range up to the stop is set so as to be freely rotatable, the detent locking portion 6a provided on the ring member 6 may be set to be rotated approximately 360 degrees. In this case, It is not necessary to rotate the ring member 6 before fitting it into the fitting recess 7 to set the jetting direction of the water. Can be set to freely set the jetting direction of the water.
[0021]
Further, for example, one of the detent locking portion 6a provided on the ring member 6 and the detent locking portion 3a provided on the nozzle body 3 is a convex portion, and the other is a concave portion fitted with the convex portion. When the concave portion is set to an interval at which the convex portion can freely rotate within a predetermined range, the convex portion hardly rotates by setting the concave portion to a very narrow range in which the convex portion rotates. In this case, the rotation of the ring member 6 due to the vibration of the automobile or the like can be prevented.
[0022]
Therefore, according to the present invention, not only can one ring member be rotated and fitted into the fitting concave portion to freely set the water jetting direction, but also it is possible to prevent excessive rotation of the ring member due to vibration and prevent this It is possible to prevent the valve body from being loosened due to the rotation, and to further adjust the jetting direction of the water by rotating the ring member in a state in which the ring member is fitted into the fitting recess without having to be removed from the fitting recess. Thus, it is possible to provide a very practical snow melting nozzle that can change the direction of jetting water very easily and at low cost.
