Abstract
Description
本発明は、車道や歩道に設置されたマンホールの蓋、住宅の床面収納庫の開閉扉、隠し階段口の開閉蓋といった蓋パネルに適用される平面取手装置に関する。 The present invention relates to a flat handle device applied to a cover panel such as a manhole cover installed on a roadway or a sidewalk, an opening / closing door of a floor storage in a house, and an opening / closing cover of a hidden staircase.
この種の重い蓋パネルにおいては、開閉や取外し時の吊上げ作業を楽に行なうために、作業者の手が掛けられるか、吊上げ用機械器具からのワイヤーが掛けられるアイボルト型の取手金具を、蓋パネルの適所に設けた螺子孔に捻じ込み装着することが行なわれている(特許文献1参照)。
蓋パネルの吊上げ作業を行なわない定常状態では、蓋パネルの前記螺子孔は上面にドライバー溝を形成した閉塞用ボルトによって埋め合わされている。この閉塞用ボルトは、吊上げ作業に当って通常の回転工具によって回され、螺子孔から抜き取られる。その後、取付金具の下端螺子軸部が当該螺子孔に捻じ込まれる。
In this type of heavy lid panel, an eyebolt type handle that can be hung by an operator or a wire from a lifting machine is attached to the lid panel in order to facilitate lifting when opening and closing and removing. A screw hole provided at an appropriate position is installed by screwing (see Patent Document 1).
In a steady state where the lifting operation of the lid panel is not performed, the screw hole of the lid panel is filled with a closing bolt having a driver groove formed on the upper surface. The closing bolt is rotated by a normal rotary tool during the lifting operation, and is extracted from the screw hole. Thereafter, the lower end screw shaft portion of the mounting bracket is screwed into the screw hole.
この従来装置では、閉塞用ボルトの上端面には、市販されている普通の回転工具が適合する通常のドライバー溝が設けられているため、閉塞用ボルトを弄くられて螺子孔から抜き取られ、空っぽとなった螺子孔に金属棒等を挿入あるいは掛合させて、蓋パネルを無断開放されてしまう危険性がある。
また、正当権限のある管理者が蓋パネルを開放するときであっても、アイボルト型の取手金具を捻じ込むときには、閉塞用ボルトを螺子孔から完全に抜き取る方式であるため、吊上げ作業中に不注意によって閉塞用ボルトを紛失してしまう危険性があった。
In this conventional device, the upper end face of the closing bolt is provided with a normal driver groove that is compatible with a commercially available ordinary rotary tool, so the closing bolt is tampered with and extracted from the screw hole. There is a risk that a metal rod or the like is inserted into or engaged with the empty screw hole and the lid panel is opened without permission.
In addition, even when an authorized administrator opens the lid panel, when the eyebolt handle is screwed in, the closure bolt is completely removed from the screw hole. There was a risk of losing the closure bolt with care.
本発明の課題は、弄くりに対して強いとともに、定常状態では蓋パネルの上面がフラットに維持されており、必要に応じて取手金具の装着相手が蓋パネルの上面に引き出され、閉塞用ボルトの紛失の危険性がない平面取手装置を提供することである。 The problem of the present invention is that it is strong against tampering, and the upper surface of the lid panel is kept flat in a steady state. It is intended to provide a flat handle device that does not have a risk of loss.
本発明の平面取手装置は、吊上げ対象の蓋パネルに上下方向に形成された受孔に嵌挿され、上端開口面が蓋パネルの上面と同一平面にあるように蓋パネルに固着されるガイド筒と、定常状態では上端面が蓋パネルの上面と同一平面にあるようにガイド筒に収容され、上端部外周面に螺子部を形成した閉塞用ボルトと、閉塞用ボルトの下端部側面に突設され、ガイド筒側面のスロットに挿入されたストッパーピンと、閉塞用ボルトの外周面の受溝に装着され、ガイド筒の内周面に圧接して閉塞用ボルトを所定のスライド位置に保持するする弾性部材と、閉塞用ボルトの上下方向の螺子孔に捻じ込まれ、定常状態では円形頭部が蓋パネルの上面と同一平面にあるように、閉塞用ボルトの上端面の逃げ用凹部に収容されており、専用回転工具の駆動部が係合する受動部を円形頭部の上面に形成した摘み用ビスと、定常状態では蓋パネルから取外されており、ガイド筒の上方に突出した閉塞用ボルトの前記螺子部に下端ナット部が螺合される取手金具とからなる。 The flat handle device of the present invention is a guide cylinder that is fitted into a receiving hole formed in a vertical direction on a lid panel to be lifted, and is fixed to the lid panel so that the upper end opening surface is flush with the upper surface of the lid panel. In a steady state, the upper end surface is accommodated in the guide cylinder so as to be flush with the upper surface of the lid panel, and a closing bolt having a screw portion formed on the outer peripheral surface of the upper end portion, and a projecting projecting side surface of the lower end portion of the closing bolt The stopper pin inserted in the slot on the side surface of the guide cylinder and the receiving pin on the outer peripheral surface of the closing bolt are elastically held in contact with the inner peripheral surface of the guide cylinder to hold the closing bolt in a predetermined slide position. It is screwed into the vertical screw hole of the member and the closing bolt, and is housed in the relief recess on the upper end surface of the closing bolt so that the circular head is flush with the upper surface of the lid panel in the steady state. And drive of a dedicated rotary tool And a lower end nut portion on the screw portion of the closing bolt protruding above the guide cylinder, which is removed from the lid panel in a steady state. And a handle metal fitting to be screwed.
このように構成された平面取手装置では、蓋パネルの吊上げを行なわない定常状態においては、閉塞用ボルトの上端面および摘み用ビスの円形頭部の上面は、蓋パネルの上面と同一平面にあるため、車両の走行、歩行者の通行、居住者の歩行あるいは器物の運搬や設置に支障を生じることがない。
蓋パネルを取外したいときには、一般には市販されていない専用回転工具の駆動部を摘み用ビスの円形頭部の受動部に係合させ、摘み用ビスを緩める方向に回転操作するため、閉塞用ボルトに対する弄くりが抑止されることになり、蓋パネルが無断開放される危険性がない。
In the flat handle device thus configured, in a steady state where the lid panel is not lifted, the upper end surface of the closing bolt and the upper surface of the circular head of the knob screw are flush with the upper surface of the lid panel. Therefore, there is no problem in traveling the vehicle, passing pedestrians, walking resident, transporting or installing the equipment.
When you want to remove the lid panel, you can engage the drive part of a special rotary tool, which is generally not commercially available, with the passive part of the circular head of the knob screw and rotate it in the direction to loosen the knob screw. Will not be tampered with, and there is no risk of the lid panel being opened without permission.
前記回転操作によって摘み用ビスの円形頭部が閉塞用ボルトの逃げ用凹部から浮き上がり、作業者が指先で摘まめる位置に突出し、この摘み用ビスを引き上げることによって、閉塞用ボルトの上端螺子部がガイド筒の上方に突出されるのであるが、閉塞用ボルトの外周面とガイド筒の内周面間に挿入された弾性部材によって適度の摩擦力が与えられているため、閉塞用ボルトの当該突出状態は安定に維持され、閉塞用ボルトの上端螺子部に対する取手金具の下端ナット部の螺合作業がスムーズになされる。 The circular head of the picking screw floats up from the relief recess of the closing bolt by the rotation operation and protrudes to a position where the operator can pick it up with a fingertip. Is projected above the guide cylinder, but since an appropriate frictional force is given by the elastic member inserted between the outer peripheral surface of the closing bolt and the inner peripheral surface of the guide cylinder, The protruding state is kept stable, and the lower end nut portion of the handle metal fitting to the upper end screw portion of the closing bolt is smoothly engaged.
前記弾性部材による摩擦力に抗して摘み用ビスを引き上げたとき、ストッパーピンがスロットの上端内面に突き当たることによって、閉塞用ボルトの引き出し量が一定に限定されるため、この平面取手装置を蓋パネルに複数箇所設置する場合、閉塞用ボルトの引き出し状態にばらつきを発生することがない。 When the picking screw is pulled up against the frictional force of the elastic member, the pull-out amount of the closing bolt is limited to a constant by the stopper pin abutting against the inner surface of the upper end of the slot. When multiple places are installed on the panel, there is no variation in the pull-out state of the closing bolt.
上記のようにストッパーピンがスロットの上端内面に突き当たることによって、閉塞用ボルトの完全なる抜き取りが阻止され、閉塞用ボルトはスライド位置においては相違していても、常にガイド筒内に保持されており、かつ、その上端螺子部に取手金具の下端ナット部が螺合されているため、従来装置のように閉塞用ボルトを作業中に紛失する危険性がない。 As described above, the stopper pin abuts against the inner surface of the upper end of the slot, so that complete removal of the closing bolt is prevented, and the closing bolt is always held in the guide cylinder even if it is different in the sliding position. In addition, since the lower end nut portion of the handle metal fitting is screwed into the upper end screw portion, there is no risk of losing the closing bolt during operation unlike the conventional apparatus.
図1から図6に示した実施例では、吊上げ対象の蓋パネル1の下面には金属製のベースプレート2が装着されており、金属製のガイド筒3の下部に溶接したロケーションプレート4が、ベースプレート2に溶接されている。上下方向に長いスロット5はガイド筒3の左右両側壁に形成されている。丸頭ビス形のストッパーピン6は、金属製の閉塞用ボルト7の直径方向の横断螺子孔8に両側から螺子軸部を捻じ込まれている。
