Description

本発明は、器具取付具および器具の取付方法に関する。 FIELD OF THE INVENTION The present invention relates to an instrument mount and a method for attaching an instrument.

既存照明のＬＥＤ化等に伴い、天井埋込型の照明器具の取替作業を行うケースが増えつつあるが、最近の照明器具は従来のものと比べて薄型化が図られているため、既設の吊り下げボルトの長さ不足により取替作業が困難になっている。このため、特許文献１には、吊り下げボルトに螺合されるネジ溝が内周に形成された筒状の軸部と、つまみ部を有する頭部とを備えるボルトを用いて、作業工程の簡素化を図ることが提案されている。 With the conversion of existing lighting to LED, cases of replacing ceiling-embedded lighting fixtures are increasing, but as recent lighting fixtures are thinner than conventional ones, existing lighting fixtures are being replaced. Replacement work is becoming difficult due to the insufficient length of the suspension bolts. For this reason, Patent Document 1 uses a bolt that includes a cylindrical shaft part with a threaded groove formed on the inner periphery to be screwed into the hanging bolt, and a head part having a knob part. Simplification is proposed.

ところが、上記特許文献１のボルトは、照明器具の取付孔に挿通した後、取付孔から抜け落ちないように照明器具と共に支持しながら、吊り下げボルトと位置合わせして螺合させる必要があるため、これら一連の作業が煩雑になり易いという問題があった。また、照明器具の取付孔の幅は、吊り下げボルトの径と略同じ大きさが一般的であるため、吊り下げボルトよりも必然的に大径となる特許文献１のボルトを取付孔に挿通できないおそれがあり、この点からも改良の余地があった。 However, after the bolt of Patent Document 1 is inserted into the mounting hole of the lighting fixture, it is necessary to align and screw it with the hanging bolt while supporting the bolt together with the lighting fixture so that it does not fall out of the mounting hole. There is a problem in that this series of operations tends to become complicated. In addition, since the width of the mounting hole of a lighting fixture is generally approximately the same size as the diameter of the hanging bolt, the bolt of Patent Document 1, which necessarily has a larger diameter than the hanging bolt, is inserted into the mounting hole. There is a possibility that this cannot be done, and there is room for improvement from this point of view as well.

以下、本発明の実施の形態について、添付図面を参照して説明する。図１は、本発明の一実施形態に係る器具取付具の縦断面図である。図１に示す器具取付具１は、両端が開口する筒状の本体１０と、本体１０の一端側に設けられた第１の雌ねじ部１２と、本体１０の他端側に設けられた第２の雌ねじ部１４および当接部１６とを備えている。器具取付具１は、例えば金属材料により形成することができる。 Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a longitudinal cross-sectional view of an instrument fixture according to an embodiment of the present invention. The instrument mount 1 shown in FIG. A female threaded portion 14 and an abutting portion 16 are provided. The instrument mount 1 can be made of, for example, a metal material.

本実施形態の第１の雌ねじ部１２および第２の雌ねじ部１４は、六角ナット等のナット状に形成されており、本体１０の両端の開口面とそれぞれ面一になるように本体１０内に配置されて、外周面の複数箇所（例えば３か所）が本体１０の内周面に溶接されて固定されている。第１の雌ねじ部１２および第２の雌ねじ部１４は、本体１０の内周面にねじ溝を形成する等して構成することもできる。本体１０は、スムーズな回転を促すことができるように円筒状であることが好ましいが、楕円筒状や多角筒状等であってもよい。 The first female threaded part 12 and the second female threaded part 14 of this embodiment are formed in the shape of a hexagonal nut or the like, and are inserted into the main body 10 so as to be flush with the opening surfaces at both ends of the main body 10. A plurality of locations (for example, three locations) on the outer circumferential surface are welded and fixed to the inner circumferential surface of the main body 10. The first female threaded portion 12 and the second female threaded portion 14 can also be configured by forming thread grooves on the inner circumferential surface of the main body 10. The main body 10 is preferably cylindrical to facilitate smooth rotation, but may also be elliptical, polygonal, or the like.

第１の雌ねじ部１２の径は、後述する吊り下げボルト５０（例えば、寸切りボルト３／８）に螺合可能な大きさであり、第２の雌ねじ部１４の径は、後述する取付ボルト２０が螺合可能な大きさである。第１の雌ねじ部１２の径および第２の雌ねじ部１４の径は、互いに同じ大きさであってもよいが、本実施形態においては、第２の雌ねじ部１４の径を第１の雌ねじ部１２の径よりも小さく設定している。 The diameter of the first female threaded portion 12 is large enough to be screwed into a hanging bolt 50 (for example, a threaded bolt 3/8), which will be described later, and the diameter of the second female threaded portion 14 is large enough to be screwed into a hanging bolt 50 (for example, a threaded bolt 3/8), which will be described later. 20 is a size that can be screwed together. The diameter of the first female threaded portion 12 and the diameter of the second female threaded portion 14 may be the same size, but in this embodiment, the diameter of the second female threaded portion 14 is the same as that of the first female threaded portion. The diameter is set smaller than the diameter of 12.

当接部１６は、第２の雌ねじ部１４に螺合された取付ボルト２０の先端部が当接するように、本体１０の内部に設けられている。本実施形態の当接部１６は、第２の雌ねじ部１４を袋ナット状に構成することで、第２の雌ねじ部１４と一体的に形成されており、取付ボルト２０の進入方向である上方に向けて半球状に膨出した形状を有している。 The contact portion 16 is provided inside the main body 10 so that the tip of the mounting bolt 20 screwed into the second female threaded portion 14 comes into contact with the contact portion 16 . The abutting portion 16 of this embodiment is formed integrally with the second female threaded portion 14 by configuring the second female threaded portion 14 in a cap nut shape, and is formed in the upper direction in which the mounting bolt 20 enters. It has a hemispherical shape that bulges out toward.

次に、上記の構成を備える器具取付具１を用いた器具の取付方法の一実施形態を説明する。既存の天井埋込型照明器具を取り外して新規な照明器具に取り替える際には、図２に示すように、照明器具６０の厚みが薄いために、天井スラブ５２等に固定された吊り下げボルト５０の長さが不足して、吊り下げボルト５０を照明器具６０の取付孔６２に挿通できないおそれがある。 Next, an embodiment of a method for attaching an instrument using the instrument attachment 1 having the above-described configuration will be described. When removing an existing ceiling-embedded lighting fixture and replacing it with a new one, as shown in FIG. There is a possibility that the hanging bolt 50 cannot be inserted into the mounting hole 62 of the lighting fixture 60 due to insufficient length.

本実施形態の器具の取付方法は、このような場合において、取付ボルト２０を、照明器具６０の取付孔６２に座金２３を介して挿通して、器具取付具１の第２の雌ねじ部１４に螺合させることにより、器具取付具１を照明器具６０に取り付ける工程（第１のステップ）を行った後、取付ボルト２０の回転により本体１０を回転させて、第１の雌ねじ部１２を吊り下げボルト５０に螺合させることにより、照明器具６０の上部を開口７２に挿入して照明器具６０を天井７０に取り付ける工程（第２のステップ）を行うものである。 In such a case, the fixture mounting method of this embodiment inserts the mounting bolt 20 into the mounting hole 62 of the lighting fixture 60 via the washer 23, and inserts the mounting bolt 20 into the second female threaded portion 14 of the fixture mount 1. After performing the process (first step) of attaching the fixture mount 1 to the lighting fixture 60 by screwing it together, the main body 10 is rotated by rotating the mounting bolt 20, and the first female threaded part 12 is suspended. By screwing into the bolt 50, the upper part of the lighting fixture 60 is inserted into the opening 72, and the process (second step) of attaching the lighting fixture 60 to the ceiling 70 is performed.

より詳細には、上記の第１ステップにおいて、図３（ａ）に示すように、取付ボルト２０を照明器具６０の取付孔６２に座金２３を介して挿入し、第２の雌ねじ部１４に対して螺進方向である矢示Ａ方向に回転させることにより、取付ボルト２０を第２の雌ねじ部１４に螺合させる。取付ボルト２０の長さは、取付ボルト２０の先端部が当接部１６に当接したときに、座金２３と取付孔６２の周縁部との間に隙間が生じるように設定されており、第１ステップにおいて、取付ボルト２０の先端部が当接部１６に当接するまで取付ボルト２０を締め付けることが好ましい。こうして、器具取付具１を照明器具６０に取り付けることにより、図２に示す照明器具６０を持ち上げた際に、器具取付具１と吊り下げボルト５０との位置合わせを容易に行うことができる。 More specifically, in the above first step, as shown in FIG. The mounting bolt 20 is screwed into the second female threaded portion 14 by rotating the mounting bolt 20 in the direction of arrow A, which is the screwing direction. The length of the mounting bolt 20 is set so that a gap is created between the washer 23 and the peripheral edge of the mounting hole 62 when the tip of the mounting bolt 20 contacts the contact portion 16. In one step, it is preferable to tighten the mounting bolt 20 until the tip of the mounting bolt 20 contacts the contact portion 16 . By attaching the fixture 1 to the lighting fixture 60 in this manner, the fixture 1 and the hanging bolt 50 can be easily aligned when the lighting fixture 60 shown in FIG. 2 is lifted.

上記の第２ステップにおいては、図３（ｂ）に示すように、取付ボルト２０を矢示Ａ方向に回転させると、取付ボルト２０の先端部が当接部１６に当接することで、取付ボルト２０が本体１０に対して相対的に回転できないため、本体１０が取付ボルト２０と共に矢示Ｂ方向に回転し、第１の雌ねじ部１２が吊り下げボルト５０に螺合する。当接部１６は、本実施形態のように取付ボルト２０の進入方向に膨出する形状を有することが好ましく、これによって、取付ボルト２０の先端周縁の全体を当接部１６に当接させることができるので、取付ボルト２０の回転により本体１０を確実に回転させることができる。但し、当接部１６の形状は、取付ボルト２０の先端部と確実に係合して本体１０を取付ボルト２０と共に回転可能な形状であればよく、必ずしも本実施形態のものには限定されない。吊り下げボルト５０の長さ不足は、本体１０の長さによって補うことができる他、取付ボルト２０の長さによっても補うことができる。 In the second step, as shown in FIG. 3(b), when the mounting bolt 20 is rotated in the direction of arrow A, the tip of the mounting bolt 20 comes into contact with the abutment part 16, so that the mounting bolt 20 is rotated in the direction of arrow A. 20 cannot rotate relative to the main body 10, the main body 10 rotates together with the mounting bolt 20 in the direction of arrow B, and the first female threaded portion 12 is screwed into the hanging bolt 50. The contact portion 16 preferably has a shape that bulges in the direction in which the mounting bolt 20 enters, as in this embodiment, so that the entire tip periphery of the mounting bolt 20 is brought into contact with the contact portion 16. Therefore, the main body 10 can be reliably rotated by rotating the mounting bolt 20. However, the shape of the abutting portion 16 is not necessarily limited to that of this embodiment, as long as it can reliably engage the tip of the mounting bolt 20 and allow the main body 10 to rotate together with the mounting bolt 20. Insufficient length of the hanging bolt 50 can be compensated for by the length of the main body 10 as well as by the length of the mounting bolt 20.

この後、図４に示すように、インパクトレンチ８０等を使用して取付ボルト２０を更に回転させることにより、器具取付具１が吊り下げボルト５０に沿って上昇し、照明器具６０の周縁部が天井７０の下面に当接する。こうして、照明器具６０の取付作業が完了する。 Thereafter, as shown in FIG. 4, by further rotating the mounting bolt 20 using an impact wrench 80 or the like, the fixture mount 1 rises along the hanging bolt 50, and the peripheral edge of the lighting fixture 60 rises. It comes into contact with the lower surface of the ceiling 70. In this way, the installation work of the lighting fixture 60 is completed.

本実施形態の器具取付具１は、取付ボルト２０により照明器具６０に取り付けた後に、取付ボルト２０の回転によって吊り下げボルト５０に螺合させることができるので、照明器具６０の取付作業を迅速容易に行うことができる。 After the fixture mount 1 of this embodiment is attached to the lighting fixture 60 using the mounting bolt 20, it can be screwed onto the hanging bolt 50 by rotating the mounting bolt 20, so that the work of installing the lighting fixture 60 is quick and easy. can be done.

また、器具取付具１自体は、照明器具６０の取付孔６２に挿通させる必要がないため、取付孔６２の幅が器具取付具１の径より小さい場合であっても作業性に影響を与えるおそれがなく、この点からも照明器具６０の取付作業を迅速容易に行うことができる。 Furthermore, since the fixture mount 1 itself does not need to be inserted into the mounting hole 62 of the lighting fixture 60, even if the width of the mounting hole 62 is smaller than the diameter of the fixture mount 1, there is a risk that workability will be affected. Also from this point of view, the installation work of the lighting fixture 60 can be performed quickly and easily.

本実施形態においては、既設の吊り下げボルトを利用して、器具取付具１により照明器具６０を天井に取り付ける場合を説明したが、器具取付具１により天井に取り付けられる器具は照明器具６０に限定されるものではなく、空調装置等の電気器具、ケーブルラック、セキュリティ器具、消防器具、音響器具、その他の設備器具など、既設の天井吊り下げボルトに支持される種々の器具を例示することができる。 In this embodiment, a case has been described in which the lighting fixture 60 is attached to the ceiling using the fixture mount 1 using an existing hanging bolt, but the fixture that can be mounted to the ceiling using the fixture mount 1 is limited to the lighting fixture 60. Examples include various appliances that are supported by existing ceiling hanging bolts, such as electrical appliances such as air conditioners, cable racks, security equipment, fire equipment, audio equipment, and other equipment. .
