Description
この発明は、防火扉に用いられる防火扉用引手に関する。 The present invention relates to a fire door pull handle used for a fire door.
防火扉は建築基準法施行令に定められ、所定の耐熱基準をクリアする構造物で、当然ながら、それに取付られる引手も、金属材料により製造され、一般的には、螺子にて防火扉に固着されていた。 The fire door is a structure that complies with the Building Standards Law Enforcement Ordinance and meets the specified heat resistance standards. Naturally, the handle attached to the fire door is also made of a metal material and is generally fixed to the fire door with screws. It had been.
防火扉においても、一般の扉と変わらず、取付の簡素化が望まれており、これによるコストの引き下げに寄与できるものであるが、今までは前述したように螺止めしか行われていなかった。しかし、金属製のロッカー扉には螺子を用いない簡素な取付手段を備えた家具用引手（特許文献１）が開示されている。
前述の家具用引手にあっては、合成樹脂を用いて製造しており、当然ながら熱に弱く、防火扉用引手に用いることは出来ない。金属製材料により同じ構造の物を作り出すことは材質の相違から不可能であった。 The furniture handle described above is manufactured using a synthetic resin and is naturally weak against heat and cannot be used as a fire door puller. It was impossible to create an object with the same structure using a metal material due to the difference in material.
そこで、この発明は、金属製材料を用いて、防火扉の取付穴に容易に装着出来るようにした防火扉用の引手を提供することを課題とする。 Then, this invention makes it a subject to provide the handle for fire doors which made it easy to mount | wear with the attachment hole of a fire door using metal materials.
この発明に係る防火扉用引手は、金属板（２）に指掛穴（３）を形成し、この指掛穴（３）の周囲で該金属板（２）の裏面に金属製の凹部を持つ凹部材（４）を取付けて防火扉用引手本体（５）を構成し、前記金属板（２）の裏面に突出する前記凹部材（４）を挟んで一方側に配され、防火扉の取付穴と係止する係止片（６）を前記凹部材（４）を介在して前記金属板（２）に設けると共に、前記凹部材（４）を挟んで前記係止片（６）と対向する他方側に配され、前記防火扉の取付穴と係止する弾性変形可能な係止突起（７）を設け、前記係止突起（７）は、一端側が平板状で、前記凹部材（４）に固着され、その他端側が曲げられた金属製の板ばね（８）の先端に形成されたことを特徴とする防火扉用引手（請求項１）。 The fire door puller according to the present invention has a finger hook hole (3) formed in a metal plate (2), and a metal recess on the back surface of the metal plate (2) around the finger hook hole (3). A recessed body (4) is attached to form a fire door pull handle body (5), arranged on one side with the recessed material (4) protruding from the back surface of the metal plate (2), A locking piece (6) for locking with the mounting hole is provided on the metal plate (2) with the recess material (4) interposed therebetween, and the locking piece (6) with the recess material (4) interposed therebetween. An elastically deformable locking projection (7) is provided on the opposite side and is locked with the mounting hole of the fire door. The locking projection (7) has a flat plate at one end, and the recess material ( 4) A fire door puller characterized in that it is formed at the tip of a metal leaf spring (8) fixed to 4) and bent at the other end.
この構成の防火用引手を防火扉に取付るには、まず防火扉用引手の係止片を防火扉の取付穴に挿入して、該係止片を防火扉の取付穴に裏面から係止する。それから、引手を取付穴に対して直進的に押圧すると、係止突起が弾性変形して引っ込み、該取付穴を通過する。そして、再び係止突起は伸びて防火扉の取付穴に裏面から係止する。即ち、係止片及び係止突起により、取付穴に簡単で、且つ確実に取付られる。 In order to attach the fireproof handle of this configuration to the fire door, first insert the locking piece of the fire door handle into the mounting hole of the fire door, and lock the locking piece from the back side to the mounting hole of the fire door. To do. Then, the straight advance to be pressed against the mounting hole of the pull tab, the locking projection is retracted by elastic deformation, to pass through the hole with said mounting. And the latching protrusion is extended again, and it latches to the attachment hole of a fire door from the back. That is, it can be easily and reliably attached to the mounting hole by the locking piece and the locking projection.
以上のように、この発明によれば、金属製の係止片と金属製の係止突起を持つ板ばねにより、防火扉用引手は、防火扉の取付穴に直進的な力を加えることで、簡単で且つ確実に取付けられることができる。 As described above, according to the present invention, the leaf spring having the metal locking piece and the metal locking protrusion allows the fire door puller to apply a straight force to the mounting hole of the fire door. It can be installed simply and reliably.
以下、この発明の実施例を図面により説明する。 Embodiments of the present invention will be described below with reference to the drawings.
図１は防火扉用引手の正面図、図２は同上の背面図、図３は図１Ａ−Ａ線断面図、図４は正面方向から見た斜視図、図５は背面方向から見た斜視図である。 1 is a front view of a fire door pull handle, FIG. 2 is a rear view of the same, FIG. 3 is a sectional view taken along line AA in FIG. 4, FIG. 4 is a perspective view seen from the front direction, and FIG. FIG.
図１乃至図５において、防火扉用引手１が示され、この防火扉用引手１は、ステンレスにより製造された所望の形状の金属板２に、その中央に方形状の指掛穴３が形成されると共に、前記金属板２の裏面で前記指掛穴３の周囲に凹部材４がスポット溶着にて取付られ、防火扉用引手本体５が形成されている。

そして、図２，図３，図５から明らかなように、金属板２の裏面に凹部材４が突出し、それを挟んで一方側に係止片６が前記凹部材（４）の長手方向に沿って設けられ、また、それと対向する他方側に係止突起７が同じく前記凹部材（４）の長手方向に沿って設けられている。
As is apparent from FIGS. 2, 3 and 5, the
板ばね８は、金属製材料により製造され、一端側が平板状で、他端側が曲げられ、その先端に前記した係止突起７が形成されている。この板ばね８は、その平板側が前記凹部材４の外面にスポット溶着されている。これにより、前述したように、係止突起７は前記係止片６と対向した位置である金属板２の裏面に近接して設けられ、前記金属板２に添って且つ指掛穴側に弾性変形するように構成されている。この係止突起７と前記係止片６の基部との寸法Ｌは、防火扉１０に形成の取付穴１１の同方向寸法よりも多少大きく形成されている。このことにより、係止片６の取付穴１１に係止される。
The
上述の構成において、防火扉用引手１を防火扉１０に取付けるには、まず、防火扉１０の取付穴１１内に係止片６を挿入し、取付穴１１の裏面に係止する。それが終了したら、主に係止突起７側を取付穴１１に対し、直進的な力を加えると、係止突起７が金属板２に添って且つ指掛穴側に弾性変形して取付穴１１を通過して、再び伸び、取付穴１１に係止され、防火扉用引手１は防火扉１０に容易に且つ確実に取付られる。
