Description

本発明は、オフィスの執務空間にて使用されるデスク等の作業面の上方に配置された棚板等の構造体の下面へ取付けて使用される照明器具等のオプション部材の取付構造に関する。   The present invention relates to a mounting structure for an optional member such as a lighting fixture that is used by being attached to the lower surface of a structure such as a shelf board arranged above a work surface such as a desk used in an office office space.

例えば、オフィスの執務室で使用されるデスクの棚板の下面に、デスク面を照射する蛍光灯などの照明器具を吊支状態で取り付ける場合には、通常、蛍光灯側に開孔した取付孔に、上方に位置する棚板に対して、取付ねじを下方から挿入しながら螺子込んで締着する、という方法が採られている。   For example, when mounting a lighting fixture such as a fluorescent lamp that irradiates the desk surface in a suspended state on the lower surface of a desk shelf used in an office office, a mounting hole that is usually opened on the fluorescent lamp side In addition, a method is adopted in which a mounting screw is screwed into a shelf plate positioned above and is fastened while being inserted from below.

このような蛍光灯の取付方法では、作業時、棚板に対して、作業者が蛍光灯を片手で保持しながら行なわねばならないことから、蛍光灯が重くて、大きい場合には、安定して保持することができず、作業性が非常に悪いばかりでなく、作業中に、蛍光灯を落下させる危険性がある。   In such a fluorescent lamp mounting method, the operator must hold the fluorescent lamp with one hand against the shelf during the operation. Therefore, when the fluorescent lamp is heavy and large, it is stable. Not only can it not be held, the workability is very bad, but also there is a risk of dropping the fluorescent lamp during the work.

前記した不具合を解消するための技術として、特許文献１に開示されているような取付構造が公知である。この特許文献１においては、棚板側に、だるま孔を設け、蛍光灯の取付部に設けた取付ねじの頭部を、前記だるま孔の大径孔部に挿通させた後に、小径孔部側に移動させることにより、蛍光灯を一旦、棚板の下面に仮保持した後、蛍光灯の移動を規制する規制部材を取り付けることにより、本固定がなされている。   As a technique for solving the above-described problems, a mounting structure as disclosed in Patent Document 1 is known. In this Patent Document 1, a dome hole is provided on the shelf plate side, and the head of the attachment screw provided in the attachment portion of the fluorescent lamp is inserted into the large diameter hole portion of the harpoon hole, and then the small diameter hole portion side. After the fluorescent lamp is temporarily held on the lower surface of the shelf plate by moving to the position, the fixing is performed by attaching a regulating member that regulates the movement of the fluorescent lamp.

しかし、この方法では、蛍光灯に設けた取付ねじの頭部を、棚板下部に設けただるま孔に引掛ける作業が必ずしも容易ではないばかりでなく、蛍光灯を仮保持するための取付ねじと、本固定するための規制部材としてのねじとをそれぞれ別個に用意する必要があることから、部品点数が多くなり、構造も複雑になるばかりでなく、棚板側には、本固定用の孔のほか、仮保持用のだるま孔等の特殊な孔明け加工を施さねばならないため、加工工数が多く、コスト高になる。しかも、棚板は、板金製の板材を対象とし、木製の板材への取付けには不適な構造であるとともに、だるま孔と、規制部材であるねじ用の孔とが近接して孔明け加工されているため、両者間の境界部に負荷が集中すると変形し易いことから、蛍光灯の荷重に応じた板厚強度を維持させる必要がある。
特開２００１−１６９８３４号公報 However, in this method, it is not always easy to hook the head of the mounting screw provided on the fluorescent lamp to the saddle hole provided at the bottom of the shelf board, and the mounting screw for temporarily holding the fluorescent lamp and Since it is necessary to prepare a screw as a restricting member for main fixing separately, not only the number of parts is increased and the structure is complicated, but also the hole for main fixing is provided on the shelf side. In addition, since special drilling such as a darling hole for temporary holding must be performed, the number of processing steps is increased and the cost is increased. Moreover, the shelf board is intended for sheet metal plate materials and is not suitable for mounting on a wooden plate material, and a daruma hole and a screw hole that is a regulating member are drilled close to each other. Therefore, it is necessary to maintain the plate thickness strength corresponding to the load of the fluorescent lamp because the load is easily deformed when the load is concentrated on the boundary portion between them.
