Description

本発明は、引戸用錠前を引戸に固定するための取り付け構造に関する。 The present invention relates to a mounting structure for fixing a sliding door lock to a sliding door.

引戸に引戸用錠前を取り付けるためには特許文献１に見られるように施錠機構を挟むように両面に取付座を配置し、両者をボルトで固定する構造が採用されている。
しかしながら、開放状態で引き戸を戸袋に収容する構造にあっては取付座の厚みを抑える必要上、取付座の強度が低下してボルトの締め付け強度に限界があるという問題がある。 In order to attach the lock for the sliding door to the sliding door, a structure in which mounting seats are arranged on both sides so as to sandwich the locking mechanism as shown in Patent Document 1 and both are fixed with bolts is adopted.
However, in the structure in which the sliding door is accommodated in the door pocket in the open state, there is a problem in that the strength of the mounting seat is lowered and the tightening strength of the bolt is limited because the thickness of the mounting seat needs to be suppressed.

本発明はこのような問題に鑑みてなされたものであって、その目的とするところは取付座の厚みにかかわりなく確実に引戸に固定することができる引戸用錠前の取付構造を提供することである。 The present invention has been made in view of such problems, and its object is to provide a sliding door lock mounting structure that can be reliably fixed to a sliding door regardless of the thickness of the mounting seat. is there.

このような課題を達成するために本発明においては、施錠機構を収容する錠箱を引戸の表裏に配置された取付座により固定する引戸用錠前の取付構造において、前記錠箱の一部に突起が貫通可能な凹部または貫通孔を設けると共に前記錠箱の固定板に開口しかつ延長線が前記凹部または貫通孔に交差するネジ孔を前記錠箱に設ける一方、前記取付座には前記凹部または貫通孔に対向する位置に引戸の移動方向に重なる突起を形成し、前記ネジ孔から挿入されたネジにより前記突起同士を固定するようにした。 In order to achieve such a problem, in the present invention, in the mounting structure for the lock for the sliding door, in which the lock box that houses the locking mechanism is fixed by the mounting seats arranged on the front and back of the sliding door, a protrusion is formed on a part of the lock box. Is provided in the lock box with a screw hole that is open to the fixing plate of the lock box and whose extension line intersects the recess or the through hole. Protrusions that overlap the moving direction of the sliding door are formed at positions facing the through holes, and the protrusions are fixed by screws inserted from the screw holes.

表裏の取付座を固定する突起が錠箱の領域で固定されている引戸の表面に露出する部分に変形が生じるのを防止できる。 It is possible to prevent the protrusions that fix the front and back mounting seats from being deformed in the portions exposed to the surface of the sliding door that is fixed in the lock box region.

そこで以下に本発明の詳細を図示した実施例に基づいて説明する。
図１は本発明の一実施例を示すものであって、引戸用錠前本体１は引戸に埋め込んだ状態で正面の固定板２の取付穴３にネジを挿入して引戸に固定される。 Therefore, details of the present invention will be described below based on the illustrated embodiment.
FIG. 1 shows an embodiment of the present invention. A lock door main body 1 is fixed to a sliding door by inserting a screw into a mounting hole 3 of a front fixing plate 2 in a state of being embedded in the sliding door.

引戸用錠前本体１は、ロック部材４などの施錠機構を格納する錠箱５の一部に後述する取付座１０、２０の突起１１、１２、２１、２２を収容する凹部６、６（もしくは貫通孔）が形成され、またこれら凹部６、６に交差するように正面側（引戸の側面側）に開口７ａ、７ａを有するネジ孔７、７が穿設されている。これらネジ孔７、７にはネジ、またはタッピングネジ８、８が好ましくは予めセットされている。 The locking door lock main body 1 has recesses 6 and 6 (or penetrating holes) that house projections 11, 12, 21, and 22 of mounting seats 10 and 20 described later in a part of a lock box 5 that stores a locking mechanism such as a lock member 4. Are formed, and screw holes 7 and 7 having openings 7a and 7a are formed on the front side (side surface side of the sliding door) so as to intersect with the recesses 6 and 6. Screws or tapping screws 8 and 8 are preferably set in advance in these screw holes 7 and 7.

一方、取付座１０、２０には錠箱３の凹部６、６に対向する位置に突起１１、１２、２１、２２が形成されている。これらの突起１１、１２、２１、２２は、引戸の表裏両面に配置される取付座１０、２０のそれぞれに引戸の移動方向の前後で重なるように配置されている。 On the other hand, projections 11, 12, 21, 22 are formed on the mounting seats 10, 20 at positions facing the recesses 6, 6 of the lock box 3. These protrusions 11, 12, 21, and 22 are disposed so as to overlap the mounting seats 10 and 20 disposed on both the front and back surfaces of the sliding door before and after the sliding door in the moving direction.

これらの突起１１、１２、２１、２２は、好ましくは中心部に長手方向に伸び、かつネジ８、８の進行方向に開口する長溝１１ａ、１２ａ、２１ａ、２２ａ（または長溝）を有するＵ字状体として構成されている。 These protrusions 11, 12, 21, 22 are preferably U-shaped having long grooves 11 a, 12 a, 21 a, 22 a (or long grooves) that extend in the longitudinal direction at the center and open in the direction of travel of the screws 8, 8. It is structured as a body.

この実施例において、引戸用錠前本体１を引戸に埋め込んで固定板２の取付穴３にネジで固定した後、その引戸の表裏に取付座１０、２０を配置すると、それぞれの取付座１０、２０の突起１１、１２、２１、２２が錠箱５の凹部６、６内で引戸の進行方向に前後するように重なる。 In this embodiment, when the lock body 1 for the sliding door is embedded in the sliding door and fixed in the mounting hole 3 of the fixing plate 2 with screws, the mounting seats 10 and 20 are arranged on the front and back of the sliding door. The protrusions 11, 12, 21, and 22 overlap in the recesses 6 and 6 of the lock box 5 so as to move back and forth in the sliding door moving direction.

この状態で開口７ａ、７ａから工具３０を挿入してネジ孔７、７のネジ８、８を締めると、ネジ８、８は突起１１、１２、２１、２２の長孔１１ａ、１２ａ、２１ａ、２２ａを通過して凹部５、５の奥側の壁面に到達し、ここに螺合する（図２Ｂ）。取り付けが完了した時点で、開口７ａ、７ａには必要に応じて孔隠用のメクラ栓９、９を挿入しておく。 In this state, when the tool 30 is inserted from the openings 7a, 7a and the screws 8, 8 of the screw holes 7, 7 are tightened, the screws 8, 8 are elongated holes 11a, 12a, 21a, It passes through 22a, reaches the inner wall surface of the recesses 5 and 5, and is screwed here (FIG. 2B). When the attachment is completed, the hole plugs 9 and 9 are inserted into the openings 7a and 7a as needed.

この実施例によれば表裏の取付座１０、２０は、それぞれの突起１１、１２、２１、２２が錠箱の領域でネジ８、８により固定されているから、取付座１０、２０の本体部分、つまり引戸の表面に露出する部分に変形が生じることはない。 According to this embodiment, the mounting seats 10 and 20 on the front and back sides of the mounting seats 10 and 20 are fixed by screws 8 and 8 in the region of the lock box. That is, the portion exposed on the surface of the sliding door is not deformed.

なお、長孔１１ａ、１２ａ、２１ａ、２２ａ、長溝の幅をネジ８、８よりも若干小さくしておくと、突起１１、１２、２１、２２にも螺合させることができる。 In addition, if the widths of the long holes 11a, 12a, 21a, 22a and the long groove are slightly smaller than those of the screws 8, 8, the protrusions 11, 12, 21, 22 can be screwed together.
