A sprinkler head accessory mounting tool (hereinafter referred to as “mounting tool”) 100 according to the first embodiment includes a
本体1は円筒形状をしており、図中下端側に把持棒2が挿通されている。穴1Aの下端側は、本体1の上端側よりも小径となっており、穴1Aは下端側から上端側に向かって拡径している。図1に示すように本体1の上端側にはスプリンクラーヘッド付属品であるスプリンクラーヘッドカバー4が収容され、スプリンクラーヘッドカバー4のカバープレート4Aは本体1の上端側の内面に支持されている。穴1Aがすり鉢形状になっていることでスプリンクラーヘッドカバー4のカバープレート4Aの高さや厚みが異なっても本体1の内周面でカバープレート4Aを支持可能である。
The main body 1 has a cylindrical shape, and a gripping rod 2 is inserted on the lower end side in the figure. The lower end side of the hole 1A has a smaller diameter than the upper end side of the main body 1, and the hole 1A increases in diameter from the lower end side toward the upper end side. As shown in FIG. 1, a sprinkler head cover 4, which is a sprinkler head accessory, is accommodated on the upper end side of the main body 1, and the cover plate 4 </ b> A of the sprinkler head cover 4 is supported on the inner surface on the upper end side of the main body 1. Since the hole 1A has a mortar shape, the cover plate 4A can be supported by the inner peripheral surface of the main body 1 even when the height and thickness of the cover plate 4A of the sprinkler head cover 4 are different.
本体1の下端には内側に突出して形成された内側フランジ11が形成されており、その中心には穴12が形成されている。内側フランジ11は把持部2の上端に形成された鍔部21を係止している。
An inner flange 11 is formed at the lower end of the main body 1 so as to protrude inward, and a hole 12 is formed at the center thereof. The inner flange 11 locks the flange portion 21 formed at the upper end of the grip portion 2.

If all or a part of the material of the main body 1 is formed of a member that can be seen through, the state of the internal sprinkler head cover 4 can be easily seen and the operability of the mounting tool 100 is improved. A transparent resin material can be used as the material of the main body 1. Alternatively, an opening or notch may be formed on the side surface of the main body 1 so that the internal sprinkler head cover 4 can be viewed.
把持棒2は細長い棒であり、前述のように上端の鍔部21が本体1の内側フランジ11に係止されている。鍔部21から少し離れた位置に鍔部22が形成されており、鍔部22の上にはコイルスプリング23が載置されている。把持棒2の外径は、本体1の下端の穴12の内径よりも僅かに小径であり、把持棒2と穴12との間に僅かな間隙を有している。
The grip rod 2 is a long and narrow bar, and the flange portion 21 at the upper end is locked to the inner flange 11 of the main body 1 as described above. A flange 22 is formed at a position slightly away from the flange 21, and a coil spring 23 is placed on the flange 22. The outer diameter of the gripping bar 2 is slightly smaller than the inner diameter of the hole 12 at the lower end of the main body 1, and there is a slight gap between the gripping bar 2 and the hole 12.
コイルスプリング23の上端には本体1の内側フランジ11が載置されている。コイルスプリング23は本体1を把持棒2の上端側へ付勢して、把持棒2の鍔部21と本体1の内側フランジ11が係止された状態を維持する作用を有する。そのためコイルスプリング23の反発力は本体1にスプリンクラーヘッドカバー4が収容された状態でスプリング23が潰れない程度の力でよい。
The inner flange 11 of the main body 1 is placed on the upper end of the coil spring 23. The coil spring 23 has an action of urging the main body 1 toward the upper end side of the gripping rod 2 and maintaining a state where the flange portion 21 of the gripping rod 2 and the inner flange 11 of the main body 1 are locked. Therefore, the repulsive force of the coil spring 23 may be such a force that the spring 23 is not crushed in a state where the sprinkler head cover 4 is accommodated in the main body 1.
上記において、本体1の内側フランジ11と把持棒2の鍔部21との係止構造は、把持棒2が本体1から抜けるのを防止する係留部として機能している。また、コイルスプリング23は把持棒2を本体1の下端側に保持する保持部材として機能している。
In the above description, the locking structure between the inner flange 11 of the main body 1 and the flange portion 21 of the gripping rod 2 functions as an anchoring portion that prevents the gripping rod 2 from coming off the main body 1. The coil spring 23 functions as a holding member that holds the gripping rod 2 on the lower end side of the main body 1.
把持棒2の下端側は作業者が握って操作する把持操作部24となっている。把持操作部24の長さは作業者が床面に立って取付作業する場合は1~2mの物を使用するのが好ましい。これとは別に作業者が脚立や作業台等の足場の上で取付作業を行う場合には把持操作部24の長さがさらに短いものを用いるとよい。
The lower end side of the grip rod 2 is a grip operation section 24 that is gripped and operated by an operator. The length of the gripping operation unit 24 is preferably 1 to 2 m when the worker performs installation work while standing on the floor. In addition to this, when the worker performs the mounting work on a scaffold such as a stepladder or work table, it is preferable to use a gripping operation unit 24 having a shorter length.
次に、第1実施形態の取付工具100を用いてスプリンクラーヘッドカバー4をスプリンクラーヘッド3に取付ける手順を説明する。
Next, a procedure for attaching the sprinkler head cover 4 to the sprinkler head 3 using the attachment tool 100 of the first embodiment will be described.
図1に示すようにスプリンクラーヘッド3は二点鎖線で描かれた天井裏の配管に接続されており、下部が天井ボードCの穴を通過して室内側に配置されている。スプリンクラーヘッドカバー4はスプリンクラーヘッド3のサポートカップ31と接続される。先ず、スプリンクラーヘッドカバー4を取付工具100の上端側から本体1に挿入させる。スプリンクラーヘッドカバー4のカバープレート4Aが、本体1の内周面に載置された状態となる。
As shown in FIG. 1, the sprinkler head 3 is connected to a pipe on the back of the ceiling drawn by a two-dot chain line, and the lower part is disposed on the indoor side through the hole of the ceiling board C. The sprinkler head cover 4 is connected to the support cup 31 of the sprinkler head 3. First, the sprinkler head cover 4 is inserted into the main body 1 from the upper end side of the attachment tool 100. The cover plate 4 </ b> A of the sprinkler head cover 4 is placed on the inner peripheral surface of the main body 1.
次に、把持操作部24を手で持ってスプリンクラーヘッドカバー4の筒部4Bをスプリンクラーヘッド3の近傍に移動させる。続いて筒部4Bの中心軸とスプリンクラーヘッド3の中心軸が同軸となるように位置を調整する。このとき本体1が透明な材料で構成されていると作業者がスプリンクラーヘッド3とスプリンクラーヘッドカバー4の位置が把握しやすい。
Next, the cylinder portion 4B of the sprinkler head cover 4 is moved to the vicinity of the sprinkler head 3 by holding the grip operation portion 24 by hand. Subsequently, the position is adjusted so that the central axis of the cylindrical portion 4B and the central axis of the sprinkler head 3 are coaxial. At this time, if the main body 1 is made of a transparent material, the operator can easily grasp the positions of the sprinkler head 3 and the sprinkler head cover 4.
続いて、把持操作部24を操作してスプリンクラーヘッドカバー4をスプリンクラーヘッド3の方向に移動させる。移動によって本体1が多少揺れた場合でも、本体1の内部にスプリンクラーヘッドカバー4が収容されているので、スプリンクラーヘッドカバー4の脱落を防止できる。筒部4Bをサポートカップ31内に挿通させる。すると筒部4Bの外周に形成された爪4Cがサポートカップ31内の溝32に接触する。さらに把持操作部24をスプリンクラーヘッド3の方向に移動させると、鍔部21が内側フランジ11から離れて把持棒2のみが図中上方へ移動して把持棒2の上端面がカバープレート4Aに接触する(図3(a)参照)。この状態において鍔部21の外周縁と本体1の内周面との間に間隙を有している。
Subsequently, the grip operation unit 24 is operated to move the sprinkler head cover 4 in the direction of the sprinkler head 3. Even when the main body 1 is slightly shaken by the movement, the sprinkler head cover 4 is housed inside the main body 1, so that the sprinkler head cover 4 can be prevented from falling off. The cylindrical portion 4B is inserted into the support cup 31. Then, the claw 4 </ b> C formed on the outer periphery of the cylindrical portion 4 </ b> B comes into contact with the groove 32 in the support cup 31. When the grip operation unit 24 is further moved in the direction of the sprinkler head 3, the collar portion 21 moves away from the inner flange 11, and only the grip bar 2 moves upward in the figure, and the upper end surface of the grip bar 2 contacts the cover plate 4 </ b> A. (See FIG. 3A). In this state, there is a gap between the outer peripheral edge of the flange portion 21 and the inner peripheral surface of the main body 1.
この状態からさらに把持操作部24をスプリンクラーヘッド3の方向に移動させると、カバープレート4Aの縁は本体1の内周面から離れて、カバープレート4Aが把持棒2の上端面に載置された状態で図中上方に移動する。そしてスプリンクラーヘッドカバー4は本体1の外部に押し出される。このとき爪4Cは弾性変形により溝32を乗り越えて爪4Cと溝32が係合する。さらに筒部4Bをサポートカップ31の奥に押込むと、筒部4Bの下方に形成されたフランジ4Dが天井ボードCに接触して、これ以上筒部4Bをサポートカップ31側に押込むことができない状態になる(図3(b)参照)。このとき本体1は上端が天井ボードCに接した状態で把持操作部24側に移動される。最後に取付工具100を図中下方に移動させて、取付作業を完了する。
When the grip operation unit 24 is further moved in the direction of the sprinkler head 3 from this state, the edge of the cover plate 4A is separated from the inner peripheral surface of the main body 1, and the cover plate 4A is placed on the upper end surface of the grip bar 2. Move upward in the figure. The sprinkler head cover 4 is pushed out of the main body 1. At this time, the claw 4C gets over the groove 32 by elastic deformation, and the claw 4C and the groove 32 are engaged. Further, when the cylindrical portion 4B is pushed into the back of the support cup 31, the flange 4D formed below the cylindrical portion 4B comes into contact with the ceiling board C, and the cylindrical portion 4B can be pushed further into the support cup 31 side. It becomes incapable state (see FIG. 3B). At this time, the main body 1 is moved to the grip operation unit 24 side with the upper end in contact with the ceiling board C. Finally, the attachment tool 100 is moved downward in the drawing to complete the attachment operation.
