Description

本発明は，戸体に設置してその施錠を行う落し錠装置に関し，例えば門扉のように屋外に設置する戸体に好適に用い得る落し錠装置に関する。 The present invention relates to an unlocking device that is installed on a door and locks the door, and more particularly to an unlocking device that can be suitably used for a door installed outdoors such as a gate.

施錠用の落し棒と，戸体の縦框内に設置して上記落し棒を透孔に挿通して該落し棒を昇降するガイド部材と，床面に埋込設置して上記落し棒を受け入れる落し棒受け部材とを備えた落し錠装置が知られており，例えば下記特許文献の落し錠装置は，落し棒受け部材に侵入した砂等の塵埃を容易に除去して，塵埃の侵入による落し錠の施錠トラブルを解消することを課題として，落し棒受け部材を内外一対の筒体によって形成し，外側の筒体の底に水抜孔を透設して床面に埋込設置する一方，内側の筒体の底にフィルターを設置して該内側の筒体を上記外側の筒体に挿脱自在に挿入することによって，内側の筒体を取外してその清掃を行って侵入塵埃の除去を行うようにしたものとされる。 A locking stick, a guide member that is installed in a vertical wall of the door body, passes the dropping stick through the through-hole and moves the dropping stick up and down, and is embedded in the floor to receive the dropping stick. For example, the locking device disclosed in the following patent document easily removes dust such as sand that has entered the dropping rod receiving member, and drops due to the intrusion of dust. In order to solve the problem of locking the lock, a drop bar receiving member is formed by a pair of inner and outer cylinders, and a water drainage hole is formed through the bottom of the outer cylinder so that it can be embedded in the floor. A filter is installed at the bottom of the cylinder and the inner cylinder is removably inserted into the outer cylinder so that the inner cylinder is removed and cleaned to remove intrusion dust. It is assumed that

この場合，侵入塵埃の除去が可能となり，落し棒受け部材に塵埃が侵入して落し棒の受入れが阻害されることに起因する施錠不能や施錠不完全の施錠トラブルを防止することが可能となる。しかし乍ら，この種の落し錠装置は，一般に金属製とされるとともに落し棒受け部材の内径は，落し棒の昇降とこれによる施開錠をスムーズになし得るように，落し棒の外径より相当程度径大とされるために，屋外設置の戸体に該落し錠装置を設置したとき，戸体が風圧や振動を受けて開閉方向に振れることに伴って，落し棒受け部材に受け入れた落し棒が揺動し，これらの間で金属音を発生するに至るところ，この戸体の振れに伴う騒音発生の問題点を解消することはできない。 In this case, it is possible to remove the intruding dust, and it is possible to prevent the locking trouble that is impossible or incompletely locked due to the dust entering the dropping bar receiving member and the reception of the dropping bar being hindered. . However, this kind of locking device is generally made of metal, and the inner diameter of the dropping bar receiving member is such that the falling bar can be lifted and unlocked smoothly by the outer diameter of the dropping bar. In order to make the diameter considerably larger, when the locking device is installed on a door installed outdoors, it is received by the dropping rod receiving member as the door swings in the opening and closing direction due to wind pressure and vibration. When the dropping bar swings and generates a metallic sound between them, the problem of noise generation due to the swinging of the door cannot be solved.

一方，落し棒の揺動を防止し騒音発生を防止するには，落し棒受け部材の内径を落し棒の外径に可及的に近似した寸法関係として，落し棒受け部材が落し棒を保持するようにすれば，戸体の振れとこれに伴う騒音発生を抑制することはできるが，例えば門扉における落し棒の外径は１．５ｃｍ程度であるのが一般であるから，これに近似した寸法関係とすると，落し棒受け部材の内径も１．５ｃｍ程度に狭小化して，例えば細棒を用いて塵埃を掻き出す等の方法によっても塵埃除去が著しく困難となって施錠トラブルに至るという結果を招来することになる。 On the other hand, in order to prevent swinging of the drop bar and prevent noise generation, the drop bar support member holds the drop bar as a dimensional relationship that approximates the outer diameter of the drop bar as much as possible. By doing so, it is possible to suppress the vibration of the door and the accompanying noise generation. However, for example, the outer diameter of the drop bar in the gate is generally about 1.5 cm, so this is approximated. In terms of dimensions, the inner diameter of the drop bar receiving member is also narrowed to about 1.5 cm. For example, dust removal with a method such as scraping out dust using a thin bar makes it extremely difficult to cause locking problems. Will be invited.

このように落し棒受け部材の侵入塵埃除去による施錠トラブルを防止すると戸体の振れに伴う落し棒の騒音発生を防止できず，逆に落し棒の騒音発生を防止すると落し棒受け部材への塵埃侵入による施錠トラブルを防止できず，これら侵入塵埃除去と騒音発生防止とは相互に相反する関係となっている。 If the locking trouble due to the removal of the intruding dust from the dropping bar receiving member is prevented in this way, the noise of the dropping bar due to the swinging of the door cannot be prevented, and conversely, if the dropping bar noise generation is prevented, the dust on the dropping bar receiving member Locking troubles due to intrusion cannot be prevented, and the removal of intrusion dust and the prevention of noise generation are in conflict with each other.

本発明はかかる事情に鑑みてなされたもので，その解決課題とするところは，落し棒受け部材の侵入塵埃除去による施錠トラブルの防止と，戸体の振れに伴う騒音発生の防止の双方をなし得るようにした落し錠装置を提供するにある。 The present invention has been made in view of such circumstances, and the problem to be solved thereof is to prevent both locking troubles by removing the intruding dust from the dropping bar receiving member and noise generation due to the shaking of the door. It is to provide a lock-and-lock device that can be obtained.

As a two-member configuration with a resin guide cap, the guide cap prevents noise from being dropped, while the guide cap is removed and the bottomed-diameter cylinder is pressed against the pressurized water by a hose, for example. The intrusion dust can be removed by discharging the water and removing the intrusion dust from the cylinder by inserting a fingertip or a narrow rod or plate. The invention according to Item 1 is embedded in a locking drop bar, a guide member that is installed in a vertical wall of a door and the drop bar is inserted into a through hole to raise and lower the drop bar, and embedded in a floor surface.

In addition, the fixing portion 51 tapers the lower end of each of the segment pieces 56 at predetermined positions in the circumferential direction of the fitting leg portions 55, in this example, four narrow segment pieces 56 positioned at intervals. The guide cap 5 of this example is further positioned on the upper surface of the ring portion 51 on a straight line passing through the center thereof. A snap-in of each of the segment pieces 56 is provided above the narrow segment piece 56 provided with a concave groove 53 for turning the coin and provided with the above-mentioned locking projection, by passing through the ring portion 51. Division that provides appropriate elasticity to enable easy and reliable locking There as having a notch hole 54 for each 56.

以上のように形成した落し錠装置Ａは，上記ガイド部材２の框固定片２１を，戸体Ａにおける戸先側の縦框ａに挿入してその内壁に対接し，該縦框ａの，例えば戸先側の側面からネジを螺入して，これを縦框内の所定高さ位置に固定してあり，また落し棒１は，戸体の該縦框ａの，同じく例えば戸先側の側面に設置した図示省略のガイドプレートに上下動自在に配置し且つ該縦框の切欠き溝を介して裏面に突出した操作摘みの裏面突出固定部に該落し棒１の上端を固定し，上記ガイド部材２における上下のガイド片２２の各透孔２３を挿通するように配置することによって，上記操作摘みを上下にスライド操作して，該ガイド部材２による落し棒１の昇降をなし得るように，該縦框ａ内に昇降自在に設置したものとしてある。 In the locking device A formed as described above, the hook fixing piece 21 of the guide member 2 is inserted into the vertical hook a on the door tip side of the door body A and is in contact with the inner wall thereof. For example, a screw is screwed in from the side surface on the door-end side, and this is fixed at a predetermined height position in the vertical shaft, and the dropping bar 1 is the same as that of the vertical rod a of the door body. The upper end of the dropping bar 1 is fixed to the back surface protruding fixing portion of the operation knob which is disposed on a guide plate (not shown) installed on the side surface of the operation knob so as to be vertically movable and protrudes to the back surface through the notch groove of the vertical rod. By arranging the through holes 23 of the upper and lower guide pieces 22 in the guide member 2 so as to be inserted, the operating knob can be slid up and down to raise and lower the drop bar 1 by the guide member 2. In addition, it is assumed that it is installed in the vertical shaft a so as to be movable up and down.

一方，落し錠装置Ａの有底径大の筒体４は，戸体Ａを閉成したときに上記落し棒１が降下する位置に合せた床面，例えば上記コンクリート床面に，そのフランジ４１を該床面に載置するように該床面に埋込設置してあり，これによって上記操作摘みのスライド操作による落し棒１の昇降によって，降下時に落し棒１を受入れて落し錠装置Ａを施錠する一方，上昇時に落し棒１を引抜き離脱して落し錠装置Ａの開錠を行うようにしてある。 On the other hand, the cylinder 4 with a large bottomed diameter of the dropping lock device A has a flange 41 on the floor surface, for example, the concrete floor surface, which matches the position where the dropping rod 1 descends when the door A is closed. Is embedded in the floor so as to be placed on the floor, and thereby the dropping bar 1 is lifted and lowered by the sliding operation of the operation knob to receive the dropping bar 1 when it is lowered and the locking device A is dropped. On the other hand, the locking device A is unlocked by pulling and removing the dropping rod 1 when it is raised.

このとき上記筒体４とガイド部材２に上記共通部材としたガイドキャップ５は，該埋込設置した筒体４に対して，その上端の開口から嵌合脚部５５を，その幅狭の区分片５６を筒体４の係止孔，特にその倒Ｌ字状の垂直溝位置に合せて下向きに押込むように嵌合し，該嵌合状態で，上記凹陥溝５３にコインを差込んで該コインを捩るように回動して，該幅狭の区分片５６に突出した固定部５７をなす矢尻状の係止突起をキャップ固定部４２をなす係止孔に係止することによって，筒体４に対する回動固定を行うとともに逆方向に回動して該係止を回動解除することによって，その取り外しを行うように着脱自在に設置してある。このとき上記係止突起の係止孔への係止は，矢尻状の係止突起におけるリング部５１側，即ち上端に突出した矢尻水平部位とその傾斜上方部位の倒Ｖ字部を，係止孔の上記垂直溝から横方向に延びる横溝に上下挟持状に引掛係止することによって，これを行うものとしてある。 At this time, the guide cap 5 that is a common member for the cylindrical body 4 and the guide member 2 has a fitting leg portion 55 from the opening at the upper end of the embedded cylindrical body 4 and its narrow section. The piece 56 is fitted so as to be pushed downward in accordance with the locking hole of the cylindrical body 4, particularly the vertical L-shaped vertical groove position, and in the fitted state, a coin is inserted into the recessed groove 53 and the coin is inserted. The cylindrical body is formed by rotating the arrow-like locking projections forming the fixing portion 57 protruding from the narrow section piece 56 into the locking holes forming the cap fixing portion 42. 4 is fixed so that it can be removed by rotating and fixing in a reverse direction and releasing the lock. At this time, the locking protrusions are locked into the locking holes by locking the arrow 51-side locking protrusions on the ring part 51 side, that is, the arrowhead horizontal part protruding from the upper end and the inverted V-shaped part of the inclined upper part. This is done by hooking and holding in a vertically sandwiched manner in a lateral groove extending laterally from the vertical groove of the hole.

一方，上記ガイド部材２に対するガイドキャップ５の設置は，その縦框ａに対する挿入固定前に，ガイド部材２の透孔２３に，その上位のガイド片２２においては上方から，下位のガイド片２２においては下方から，その嵌合脚部５５をそれぞれ押込むように嵌合するとともに，その幅狭の区分片５６に配置した係止突起を弾発的に通過させ，該係止突起の上記矢尻水平部位をガイド片における透孔２３の外周縁部にスナップイン状に引掛係止することによって，その固定的な設置を行うものとしてある。 On the other hand, the guide cap 5 is installed on the guide member 2 in the through hole 23 of the guide member 2 from the upper side in the upper guide piece 22 and in the lower guide piece 22 before the insertion and fixing to the vertical rod a. From below, the fitting legs 55 are fitted so as to be pushed in, and the locking projections arranged on the narrow segment pieces 56 are elastically passed through, so that the arrowhead horizontal portion of the locking projections is passed through. The guide piece is fixedly installed by being snapped into and engaged with the outer peripheral edge portion of the through hole 23.

このようにガイドキャップ５を設置した落し錠装置Ａは，ガイド部材２による落し棒１の昇降及び落し棒受け部材３の有底径大の筒体４への落し棒１の受け入れを，それぞれガイドキャップ５の挿通孔５２を遊嵌状に挿通するか，保持状に挿通するように，該ガイドキャップ５を介して行うことによって，そのいずれの場合も，戸体Ａが風圧や振動を受けても，これによる落し棒１の騒音発生を防止することができ，本例のように極く僅かなクリアランスを残して保持状に挿通案内することによって風圧や振動による戸体Ａの振れの可能性を解消して騒音発生を完全に解消することができる。 In this way, the locking device A having the guide cap 5 installed therein guides the lifting and lowering of the dropping bar 1 by the guide member 2 and the reception of the dropping bar 1 to the cylindrical body 4 having a large bottom diameter of the dropping bar receiving member 3. By performing the insertion through the insertion hole 52 of the cap 5 in a loose-fitting manner or through the guide cap 5 so as to be inserted into a holding shape, the door body A is subjected to wind pressure or vibration in either case. However, it is possible to prevent noise from the dropping rod 1 due to this, and the possibility of the swinging of the door body A due to wind pressure or vibration by inserting and guiding the holding rod with a very slight clearance as in this example. The noise generation can be completely eliminated.

更に落し棒受け部材３を有底径大の筒体４とガイドキャップ５の複数，特に２部材構成とするとともに該ガイドキャップ５を着脱自在としたことによって，上記筒体４の内径を，落し棒１の径とは無関係とし，塵埃除去の観点からその寸法設定をなし得るようにすることができ，本例にあっては該内径を，例えば上記２ｃｍ程度としたことによって，上記回動固定したガイドキャップ５を，コインによって逆方向に回動してその筒体４に対する係止を回動解除して，該ガイドキャップ５を筒体４から取り外せば，該筒体４に侵入した塵埃を，上記ホースによる加圧水の放水，指先や幅狭の棒乃至板等を挿入等によって掻き出す如くにする等して，可及的簡易且つ確実に侵入塵埃除去を行うことができ，塵埃の侵入による施錠不完全，施錠不能といった施錠トラブルを同時に解消することができる。このとき本例にあって筒体４における底面のコーナーを湾曲したことによってコーナーに塵埃が残るのを可及的に防止することができる。 Further, the dropping rod receiving member 3 is composed of a plurality of, in particular, two member cylinders 4 and guide caps 5 having a large bottomed diameter, and the guide cap 5 is made detachable, so that the inner diameter of the cylinder 4 is reduced. It is independent of the diameter of the rod 1 and can be dimensioned from the viewpoint of dust removal. In this example, the inner diameter is set to about 2 cm, for example, so that the rotation is fixed. When the guide cap 5 is rotated in the opposite direction by a coin to release the lock on the cylinder 4 and the guide cap 5 is removed from the cylinder 4, dust that has entered the cylinder 4 is removed. Intrusion dust can be removed as easily and surely as possible by discharging pressurized water with the hose and scraping the fingertips or narrow bars or plates by insertion, etc. Incomplete, unlockable It is possible to eliminate it said was locked trouble at the same time. At this time, in this example, it is possible to prevent dust from remaining in the corner as much as possible by curving the bottom corner of the cylindrical body 4.

図示した例は以上のとおりとしたが，落し棒受け部材における有底径大の筒体の底面を全体に亘って下方突出状に湾曲して，上記放水による塵埃除去を容易化すること，該底面に水抜き孔を透設して雨水による塵埃の硬化を可及的に防止すること，ガイド部材を透孔を透設したブロック状乃至プレート状のものとしてこれにガイドキャップを設置すること，筒体とガイド部材の双方にガイドキャップを用いるとき，該ガイドキャップをそれぞれ別の部材とすること，落し錠装置を伸縮門扉における縦框，即ち走行框に設置するものとすること等を含めて，本発明の実施に当って，落し棒，ガイド部材，落し棒受け部材，その筒体，ガイドキャップの具体的形状，構造，材質，これらの関係，これらに対する付加等は，上記発明の要旨に反しない限り様々な形態のものとすることができる。 Although the illustrated example is as described above, the bottom surface of the large-bottomed cylinder in the drop bar receiving member is curved in a downward projecting shape over the whole to facilitate the dust removal by the water discharge, Providing a drain hole on the bottom surface to prevent the hardening of dust by rainwater as much as possible; installing a guide cap on the guide member as a block or plate having a through hole; When guide caps are used for both the cylinder and the guide member, the guide caps must be separate members, and the locking device must be installed on the vertical rod in the telescopic gate, that is, on the traveling rod. In practicing the present invention, the dropping rod, guide member, dropping rod receiving member, its cylindrical body, the specific shape, structure, material, relationship thereof, addition to these, etc. are included in the gist of the above invention.
