Description

本発明は、クレセント受け金具の強度補強を図ったクレセント錠に関する。   The present invention relates to a crescent lock in which the strength of a crescent bracket is reinforced.

従来より、引き違い窓等のサッシ用施錠装置としてクレセント錠が知られている。このクレセント錠は、図6に示されるように、室内障子54の縦框に取り付けられるベース金物51と、このベース金物51に対してクレセント軸53を介して回動自在に取り付けられた笠金状のクレセント52と、室外障子55に取り付けられ前記クレセント52が係合するためのフック部56aを有するクレセント受け金具56とからなる施錠装置50である(例えば、下記特許文献1等参照)。
特開平11−93488号公報
Conventionally, a crescent lock is known as a locking device for a sash such as a sliding window. As shown in FIG. 6, the crescent lock has a base metal 51 attached to the vertical shaft of the indoor shoji 54, and a bezel-like shape rotatably attached to the base metal 51 via a crescent shaft 53. Of the crescent 52 and a crescent bracket 56 having a hook portion 56a attached to the outdoor shoji 55 and engaged with the crescent 52 (see, for example, Patent Document 1 below).
Japanese Patent Laid-Open No. 11-93488

しかしながら、前記クレセント受け金具56は、図7(A)(B)に示されるように、所定形状に裁断した薄板を曲げ加工した金具を使用しているため、障子の召合せ框部分にバールなどを差し込んで強引に障子の開方向に力を加えると、図8に示されるように、クレセント受け金具56のフック部分56aが外側に大きく変形してクレセント52から外れ、障子がこじ開けられてしまうことがあった。   However, as shown in FIGS. 7 (A) and 7 (B), the crescent bracket 56 uses a bracket obtained by bending a thin plate cut into a predetermined shape. When the force is applied forcibly in the opening direction of the shoji, as shown in FIG. 8, the hook portion 56a of the crescent bracket 56 is greatly deformed to the outside and disengages from the crescent 52, so that the shoji can be pry open. was there.

一方で、納まりに制限の無い部材であれば、厚みを大きくしたり補強リブを形成するなどの一般的な剛性を増す処理や加工を施すことにより変形が起こらない構造とすることが可能であるけれども、クレセント受け金具の場合には、室内外面に隣接する障子が互いに開閉されるため、所定の厚み内で処理しなければならない等の制約があるとともに、製作コストの点からも加工が単純で済むことが強く要求される。   On the other hand, if the member has no limit on the fit, it is possible to make a structure in which deformation does not occur by applying a general rigidity increasing process such as increasing the thickness or forming a reinforcing rib. However, in the case of the crescent bracket, since the shojis adjacent to the interior and exterior surfaces are opened and closed with each other, there are restrictions such as processing within a predetermined thickness, and processing is also simple from the viewpoint of manufacturing cost. There is a strong demand for it.

そこで本発明の主たる課題は、一般的な加工処理によってクレセント受け金具の強度補強を図り、バール等によるこじ開けによっても解錠されない堅固なクレセント錠を提供することにある。   Therefore, a main object of the present invention is to provide a strong crescent lock that is not unlocked even by prying off with a bar or the like, by strengthening the strength of the crescent bracket by a general processing.

以下、本発明の実施の形態について図面を参照しながら詳述する。
図1は本発明に係るクレセント錠1の斜視図、図2はクレセント受け金具8の側面図及び正面図、図3はその平面図である。
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a perspective view of a crescent lock 1 according to the present invention, FIG. 2 is a side view and a front view of a crescent bracket 8, and FIG. 3 is a plan view thereof.

クレセント錠1は、図1に示されるように、室内障子2の縦框に取り付けられるベース金物5と、このベース金物5に対してクレセント軸6を介して回動自在に取り付けられたクレセント7とからなる施錠側金物4と、室外障子3に取り付けられ、前記クレセント7が係合するためのフック部8aを備えたクレセント受け金具8とから構成される。   As shown in FIG. 1, the crescent lock 1 includes a base metal 5 attached to the vertical shaft of the indoor shoji 2, and a crescent 7 attached to the base metal 5 via a crescent shaft 6 so as to be rotatable. And a crescent bracket 8 having a hook portion 8a that is attached to the outdoor shoji 3 and engages with the crescent 7.

そして、前記クレセント7に一体的に形成された操作レバー7Aを摘み、クレセント7をほぼ180度範囲で回動させることにより、クレセント7の周囲に形成された、壁高を漸次テーパー状に変化させた環状周壁7Bが前記クレセント受け金具8に形成されたL字状のフック部8aに対して係脱し、窓の施錠または解錠が成されるようになっている。   Then, the operation lever 7A formed integrally with the crescent 7 is picked, and the crescent 7 is rotated in a range of about 180 degrees, so that the wall height formed around the crescent 7 is gradually changed to a tapered shape. The annular peripheral wall 7B is engaged with and disengaged from the L-shaped hook portion 8a formed on the crescent bracket 8, and the window is locked or unlocked.

本発明では特に、バールなどにより障子が強引にこじ開けられ家屋に侵入される強盗事件が多発している事情に鑑み、前記クレセント受け金具8の強度補強を図るようにした。以下、具体的に図2及び図3に基づいて詳述する。   In particular, in the present invention, the strength of the crescent metal fitting 8 is reinforced in view of the fact that burglar cases in which shojis are forcibly opened by bar or the like and invaded into the house are frequently occurring. Hereinafter, it will be described in detail based on FIG. 2 and FIG.

クレセント受け金具8は、略方形金属板の加工によって成形される部材であり、図2に示されるように、ビス孔8b、8bが形成された室外障子3に対する固定部8Aと、クレセント7が係合するためのフック部8aが形成されたブラケット部8Bとから構成されている。   The crescent bracket 8 is a member formed by processing a substantially rectangular metal plate. As shown in FIG. 2, the fixing portion 8A for the outdoor shoji 3 in which the screw holes 8b and 8b are formed and the crescent 7 are engaged. It is comprised from the bracket part 8B in which the hook part 8a for joining was formed.

前記固定部8Aとブラケット部8Bとの境界部には図3に示されるように、ブラケット部8Bが室外側に偏倚するように段差部8Cが形成され、室外障子3に取り付けられた状態で、フック部8a及び後述の起立リブ8cが室内障子2に接触又は衝突しないようになっている。   As shown in FIG. 3, a stepped portion 8C is formed at the boundary portion between the fixed portion 8A and the bracket portion 8B so that the bracket portion 8B is biased to the outdoor side, and is attached to the outdoor shoji 3, The hook portion 8 a and a later-described standing rib 8 c are configured not to contact or collide with the indoor shoji 2.

前記ブラケット部8Bにおいては、内部が切り抜かれ、この切り抜き部を囲むように先端側枠片部8D、上部枠片部8Eおよび下部枠片部8Fとが夫々形成され、前記先端側枠片部8Dの内側辺に連続して前記クレセント7に係合するフック部8aが形成されているとともに、外側辺に連続して断面略L字状に屈曲する起立リブ8cが形成され、かつ前記上部枠片部8Eおよび下部枠片部8Fの面にそれぞれ、プレス加工によって与えられた凹凸による平面リブ8e、8fが形成されている。   In the bracket portion 8B, the inside is cut out, and a front end frame piece portion 8D, an upper frame piece portion 8E, and a lower frame piece portion 8F are formed so as to surround the cut out portion, and the front end side frame piece portion 8D is formed. A hook portion 8a is formed on the inner side of the upper portion of the upper frame piece. Flat ribs 8e and 8f are formed on the surfaces of the portion 8E and the lower frame piece portion 8F, respectively, by unevenness provided by pressing.

そして、前記起立リブ8cが先端側枠片部8Dの上部領域及び下部領域まで延長して形成されているとともに、前記平面リブ8e、8fが先端側枠片側8D側に連続して形成され、前記先端側枠片8Dの上部領域及び下部領域において、前記起立リブ8cの形成領域前記平面リブ8e、8fの形成領域とが先端側枠片部8Dの長手方向線上で重なり代S、Sをもって共に形成されている。 The standing rib 8c is formed to extend to the upper region and the lower region of the tip side frame piece portion 8D, and the planar ribs 8e and 8f are continuously formed on the tip side frame piece side 8D side, in the upper and lower regions of the tip-side frame piece 8D, wherein the planar rib 8e and forming regions of the standing ribs 8c, 8f longitudinal overlap on a line generations S formation region and the tip-side frame piece section 8D of, together with S Is formed.

なお、図示例では前記先端側枠片部8Dの中央部において、フック部8aと起立リブ8cとの間にも水平方向(幅方向)に沿って凹凸による平面リブ8gが形成されている。   In the illustrated example, a flat rib 8g having irregularities is formed along the horizontal direction (width direction) between the hook portion 8a and the standing rib 8c at the center portion of the distal end side frame piece portion 8D.

前記起立リブ8c、平面リブ8e、8fを有しない従来形状のクレセント受け金具(図7(B)参照)の場合、障子2,3をバールによりこじ開け前記フック部8aに過度の力Fを加えると、前記フック部8aのみが大きく変形するのではなく、上部枠片部8Eおよび下部枠片部8Fが曲げ変形を受けると同時に、先端側枠片部8Dの上部領域及び下部領域が捻れるように変形しフック部8aがクレセント7の環状周壁7Bから外れることが実験により明らかとなった。   In the case of a conventional crescent bracket (see FIG. 7B) that does not have the upstanding ribs 8c and the flat ribs 8e, 8f, the shoji 2 and 3 are pry open with a bar and an excessive force F is applied to the hook portion 8a. The upper frame piece portion 8E and the lower frame piece portion 8F are subjected to bending deformation, and at the same time, the upper region and the lower region of the distal end side frame piece portion 8D are twisted, not only the hook portion 8a is greatly deformed. It has been clarified by experiments that the hook portion 8a is deformed and comes off from the annular peripheral wall 7B of the crescent 7.

そこで、本クレセント錠1では、前記上部枠片部8Eおよび下部枠片部8Fの面にそれぞれ凹凸による平面リブ8e、8fを形成することにより断面剛性を高め、曲げによる変形を抑制するようにするとともに、前記先端側枠片8Dの外側辺に連続して断面略L字状に屈曲する起立リブ8cを形成することにより先端側枠片部8Dの断面剛性を高め、曲げ変形及び捻れ変形を抑制するようにした。   Therefore, in the present crescent tablet 1, the cross-sectional rigidity is enhanced by forming uneven ribs 8e and 8f with irregularities on the surfaces of the upper frame piece 8E and the lower frame piece 8F, respectively, and deformation due to bending is suppressed. At the same time, by forming an upstanding rib 8c that bends in a substantially L-shaped cross section continuously to the outer side of the front end side frame piece 8D, the cross section rigidity of the front end side frame piece portion 8D is increased, and bending deformation and twist deformation are suppressed. I tried to do it.

さらに、前記平面リブ8e、8fを上部枠片部8Eおよび下部枠片部8Fの部材長手方向に沿って直線状に形成した実験では、先端側枠片部8Dと、上部枠片部8Eおよび下部枠片部8Fとの結合部分に補強の不連続部、すなわち前記起立リブ8cや平面リブ8e,8fによって補強されていない未補強部ができてしまうことになり、ここで大きく捻れ変形が生じてしまうことが知見された。従って、前述のように、前記起立リブ8cを先端側枠片部8Dの上部領域及び下部領域まで延長して形成するとともに、前記平面リブ8e、8fを先端側枠片8D側に連続して形成し、前記先端側枠片部8Dの上部領域及び下部領域において、前記起立リブ8cの形成領域前記平面リブ8e、8fの形成領域が先端側枠片部8Dの長手方向線上で重なり代S、Sをもって形成するようにした。その結果、先端側枠片部8Dと上部枠片部8Eおよび下部枠片部8Fとの結合部分に補強の不連続部が無くなり、障子2,3をバールによりこじ開けてもクレセント錠1が解錠されるのを防止できるようになった。 Further, in the experiment in which the planar ribs 8e and 8f are formed linearly along the member longitudinal direction of the upper frame piece portion 8E and the lower frame piece portion 8F, the distal end side frame piece portion 8D, the upper frame piece portion 8E and the lower frame piece portion 8E A discontinuous portion of reinforcement, that is, an unreinforced portion that is not reinforced by the standing ribs 8c and the planar ribs 8e and 8f is formed at the joint portion with the frame piece portion 8F, and a large twist deformation occurs here. It was found that. Therefore, as described above, the standing rib 8c is formed to extend to the upper region and the lower region of the distal end side frame piece 8D, and the planar ribs 8e and 8f are continuously formed on the distal end side frame piece 8D side. and, in the upper and lower regions of the distal-side frame piece section 8D, the overlap in the longitudinal direction line of the planar rib 8e and forming regions of the standing ribs 8c, and 8f forming region tip-side frame piece section 8D cash S , S was formed. As a result, there is no reinforcing discontinuity at the joint between the tip side frame piece 8D, the upper frame piece 8E, and the lower frame piece 8F, and the crescent lock 1 is unlocked even if the shoji 2 and 3 are pry open with a bar. Can be prevented.
