Description
本発明は、空調室内機の取付金具に取り付けられた天井からの吊りボルトが地震のような大きな揺れが建物に入力した際に、吊りボルトから前記取付金具が脱落するようなことがない空調機器の脱落防止金具に関する。 The present invention relates to an air conditioner in which the mounting bracket is not dropped from the suspension bolt when a large swing such as an earthquake is input to the building by the suspension bolt attached to the mounting bracket of the air conditioning indoor unit. This relates to a metal fitting for preventing dropout.
従来よりビルやマンションのような建築物の天井スラブに埋設されたアンカー或いは一般家屋の天井部分から吊りボルトを垂下させ、防振金具を介して空調室内機の側面に取り付けられた取付金具に吊りボルトの下端部を取り付けて空調室内機をシステム天井に一致させて設置していた。 Conventionally, hanging bolts are suspended from anchors embedded in ceiling slabs of buildings such as buildings and condominiums, or ceilings of ordinary houses, and suspended on mounting brackets attached to the side surfaces of air-conditioning indoor units via vibration-proof fittings. The lower end of the bolt was attached and the air conditioning indoor unit was installed in line with the system ceiling.
取付金具の形状は、空調室内機メーカーによって異なるが基本的には空調室内機の側面に取り付けられる金具本体と、金具本体の上端から屈曲されて水平に延びる水平取付片並びに該水平取付片の先端を下向きに折曲した折曲片とで構成されており、折曲片から水平取付片の中央に至る切欠溝が形成されている。そして、この切欠溝に側方から吊りボルトの下端部分を挿入し、水平取付片を上下からナット締めをして固定するようにしていた（特許文献１）。 The shape of the mounting bracket varies depending on the manufacturer of the air conditioning indoor unit, but basically the bracket main body that is attached to the side surface of the air conditioning indoor unit, the horizontal mounting piece that is bent from the upper end of the bracket main body and extends horizontally, and the tip of the horizontal mounting piece And a notched groove that extends from the folded piece to the center of the horizontal mounting piece is formed. And the lower end part of the suspension bolt was inserted into this notch groove from the side, and the horizontal mounting piece was fixed by tightening the nut from the top and bottom (Patent Document 1).
処がこのような空調室内機の設置部分は作業者の手が届きにくい高い天井部分にあって、水平取付片を上下から確実にナット掛けをして固定するという作業が必ずしもなされないこともあり、或いは長期間の間に緩むということもあり、単に、空調室内機の四側面が取付金具によって吊りボルトに係止されているだけということもあった。 However, the installation part of such an air conditioner indoor unit is located on a high ceiling where it is difficult for the operator to reach, and the work of securing the horizontal mounting piece from above and below with a nut is not necessarily performed. Or it may be loosened over a long period of time, and the four side surfaces of the air-conditioning indoor unit may simply be locked to the suspension bolt by the mounting bracket.
このような状況で建物に大きな地震が入力すると建物全体が大きく揺れ、水平方向及び垂直方向において天井スラブと空調室内機との間に大きな相対変位と取付部分に大きな力が加わり、前記切欠溝から吊りボルトが外れ、空調室内機が室内に転落するというような事故があった。 In this situation, if a large earthquake is input to the building, the entire building will shake greatly, and a large relative displacement and a large force will be applied to the mounting part between the ceiling slab and the air conditioning indoor unit in the horizontal and vertical directions. There was an accident where the suspension bolts were removed and the air conditioning indoor unit fell into the room.
本発明はこのような従来の問題を解決するためになされたもので、本発明の課題は、たとえナットの緩みや、締め忘れがあったとしてもワンタッチで確実に吊りボルトと取付金具とを固定できる脱落防止金具を提供することにある。 The present invention has been made to solve such conventional problems. The object of the present invention is to securely fix the suspension bolt and the mounting bracket with one touch even if the nut is loosened or forgotten to tighten. An object of the present invention is to provide a drop-off prevention fitting that can be used.

以下、本発明の第１実施例を図１〜６に従って説明する。本発明に係る脱落防止金具(10)が適用される取付金具(1)は、空調室内機(M)の側面に装着され、吊りボルト(6)が取り付けられるものである。形状は空調機メーカーによってさまざまなものがあるが、基本的には１枚の金属板をプレス成形のみ或いはこれに折り曲げ加工を併用して形成したもので、空調室内機(M)の側面に取り付けられる金具本体(2)と、金具本体(2)の上端から屈曲されて水平に延びる水平取付片(3)並びに該水平取付片(3)の先端を下向き（即ち、金具本体(2)側）に折曲した折曲片(4)とで構成され、折曲片(4)から水平取付片(3)の中央に至る吊りボルト(6)の取付用切欠溝(5)が形成されている。折曲片(4)は上記のように空調室内機(M)を装着した場合に通常は下向きに取り付けられるが、勿論、折曲片(4)を上向きに取り付けてもよく、本発明に係る脱落防止金具(10)はその場合でも対応可能である。 Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. The mounting bracket (1) to which the drop-off prevention bracket (10) according to the present invention is applied is mounted on the side surface of the air conditioning indoor unit (M), and the suspension bolt (6) is mounted thereon. There are various shapes depending on the manufacturer of the air conditioner, but basically a single metal plate is formed only by press molding or combined with bending and attached to the side of the air conditioning indoor unit (M). Bracket body (2), horizontal mounting piece (3) that is bent from the upper end of the bracket body (2) and extends horizontally, and the tip of the horizontal mounting piece (3) faces downward (that is, the bracket body (2) side) And a notch groove (5) for mounting the suspension bolt (6) extending from the bent piece (4) to the center of the horizontal mounting piece (3) is formed. . When the air-conditioning indoor unit (M) is mounted as described above, the bent piece (4) is normally attached downward, but of course, the bent piece (4) may be attached upward, and according to the present invention. The drop-off prevention fitting (10) can be used even in that case.
取付用切欠溝(5)の形状は吊りボルト(6)と空調室内機(M)との位置調整を容易にするために溝奥が溝入口に対して両方向に直角に切り取られたＴ字状に形成されている。そして、折曲片(4)は吊りボルト(6)に螺着されたナット(20)が脱落しないだけの十分な高さを持っている。 The shape of the mounting notch groove (5) is T-shaped with the groove depth cut off at right angles in both directions with respect to the groove inlet to facilitate position adjustment of the suspension bolt (6) and the air conditioning indoor unit (M). Is formed. The bent piece (4) has a height sufficient to prevent the nut (20) screwed to the suspension bolt (6) from falling off.
第１実施例の脱落防止金具(10)は本体プレート(11)と、本体プレート(11)に形成された突起(16)とで構成されている。本体プレート(11)は１枚の長方形の金属板をプレス成形して略Ｕ字形、換言すれば金具本体(2)と折曲片(4)との間に挿入される側の辺(11a)から反対側の辺(11b)に向かって固定用切欠溝(14)が形成された二股形状をなし、該固定用切欠溝(14)は取付金具(1)への装着時に取付用切欠溝(5)に至り、取付用切欠溝(5)と固定用切欠溝(14)とが重なり合い、且つ、二股形状の本体プレート(11)を構成する一方の片が取付用切欠溝(5)の開口部分に重なって吊りボルト(6)の挿通空間(6a)を構成する。そして前記一方の片が交差片(12)となる。本体プレート(11)の幅は、金具本体(2)と折曲片(4)の内側の間隔よりやや狭い。固定用切欠溝(14)の幅はＴ字状に形成されている取付用切欠溝(5)の溝奥部分の幅に等しい。 The drop-off prevention metal fitting (10) of the first embodiment includes a main body plate (11) and a protrusion (16) formed on the main body plate (11). The body plate (11) is substantially U-shaped by press-molding one rectangular metal plate, in other words, the side (11a) on the side inserted between the bracket body (2) and the bent piece (4) It has a bifurcated shape with a fixing notch groove (14) formed from the side toward the opposite side (11b), and the fixing notch groove (14) is a mounting notch groove ( 5), the mounting cutout groove (5) and the fixing cutout groove (14) overlap, and one piece constituting the bifurcated body plate (11) is the opening of the mounting cutout groove (5). An insertion space (6a) for the suspension bolt (6) is formed so as to overlap the portion. The one piece becomes a cross piece (12). The width of the main body plate (11) is slightly narrower than the inner space between the metal fitting body (2) and the bent piece (4). The width of the fixing notch groove (14) is equal to the width of the groove back portion of the mounting notch groove (5) formed in a T-shape.
突起(16)は交差片(12)にプレス成形時に同時に形成されるか、又はこれに別部材を溶接して形成されるか或いは切り起こしによって形成される。切り起こしの場合は突起(16)となる切り起こし片が、図５(b)のように引き抜き側である場合には、突起(16)の切り起こし先端が取付用切欠溝(5)の内側面に当接して脱落防止金具(10)の抜け落ちを効果的に設置する。 The protrusion (16) is formed on the intersecting piece (12) at the same time as the press molding, or is formed by welding another member to this or by cutting up. In the case of cut and raised, if the cut and raised piece that becomes the protrusion (16) is on the drawing side as shown in FIG. 5 (b), the cut and raised tip of the protrusion (16) is in the notch for mounting (5). The drop-off prevention fitting (10) is effectively installed by coming into contact with the side surface.
その形状は図の実施例では平面視正方形で側面が傾斜した截頭角錐台形をしている。図の突起(16)は、作図上、コーナー部分や角部分は角張っているように記載されているが、通常、コーナー部分や角部分は円弧でつながれている。前記形状は勿論、正方形に限られず、図示していないが半球状、截頭円錐台形など適宜形状が選択される。形成位置は、脱落防止金具(10)を取付金具(1)に装着し、固定用切欠溝(14)が取付用切欠溝(5)に至って取付用切欠溝(5)と固定用切欠溝(14)とが重なり合い、且つ、交差片(12)が取付用切欠溝(5)の開口部分に重なって吊りボルト(6)の挿通空間(6a)を構成した時に、取付用切欠溝(5)に一致する交差片(12)の取付金具(1)側の面に取付金具(1)側に向けて突設される。突起(16)は取付用切欠溝(5)に一致して嵌り込む大きさが好ましく、その高さも取付金具(1)の板厚或いは若干それより大である事が好ましい。 In the embodiment shown in the figure, the shape is a truncated pyramid with a square in plan view and a side surface inclined. In the drawing, the protrusion (16) is shown in the drawing so that the corners and corners are angular, but usually the corners and corners are connected by arcs. Of course, the shape is not limited to a square, and although not shown, a suitable shape such as a hemispherical shape or a truncated frustoconical shape is selected. Attach the mounting bracket (1) to the mounting bracket (1), and the fixing notch groove (14) reaches the mounting notch groove (5) and the mounting notch groove (5) and fixing notch groove ( 14), and when the intersecting piece (12) overlaps the opening of the mounting notch groove (5) to form the insertion space (6a) of the suspension bolt (6), the mounting notch groove (5) Are projected toward the mounting bracket (1) side on the surface of the mounting bracket (1) side of the cross piece (12) that coincides with. The protrusion (16) is preferably sized to fit into the mounting notch groove (5), and the height thereof is also preferably slightly larger than the plate thickness of the mounting bracket (1).
しかして、空調室内機(M)を吊りボルト(6)に取り付けるに当っては、図１に示すように空調室内機(M)を天井の所定の高さで保持し、天井スラブから吊下げられた吊りボルト(6)の下端部を空調室内機(M)の側面に取り付けられた金具本体(2)の水平取付片(3)に対してその側方から挿入する。吊りボルト(6)には所定の間隔をあけて上下にナット(20)(21)が螺入されており、水平取付片(3)の挿入は上下のナット(20)(21)間で行われる。 Therefore, when attaching the air conditioning indoor unit (M) to the suspension bolt (6), hold the air conditioning indoor unit (M) at a predetermined height of the ceiling as shown in Fig. 1 and suspend it from the ceiling slab. The lower end of the suspended bolt (6) is inserted from the side of the horizontal mounting piece (3) of the metal fitting body (2) attached to the side surface of the air conditioning indoor unit (M). Nuts (20) and (21) are screwed up and down on the suspension bolt (6) at a predetermined interval, and the horizontal mounting piece (3) is inserted between the upper and lower nuts (20 and 21). Is called.
この状態で脱落防止金具(10)の固定用切欠溝(14)側の辺(11a)を吊りボルト(6)側に向け、水平取付片(3)の下面に合わせてセットし、次いで水平取付片(3)方向に水平に移動させ、金具本体(2)と折曲片(4)との間に脱落防止金具(10)の一方の辺(11a)を挿入し、交差片(12)の突起(16)が取付用切欠溝(5)に一致して嵌り込むまで挿入する。これによって固定用切欠溝(14)と取付用切欠溝(5)とが重なり合い、且つ、交差片(12)が取付用切欠溝(5)の開口部分を閉塞して吊りボルト(6)の周囲を取り囲む挿通空間(6a)が形成される。 In this state, set the side (11a) on the fixing notch groove (14) side of the drop-off prevention bracket (10) to the suspension bolt (6) side and set it according to the bottom surface of the horizontal mounting piece (3), Move horizontally in the direction of the piece (3), insert one side (11a) of the drop-off prevention bracket (10) between the bracket body (2) and the bent piece (4), and Insert until the protrusion (16) fits in the mounting groove (5). As a result, the fixing notch groove (14) and the mounting notch groove (5) overlap, and the cross piece (12) closes the opening of the mounting notch groove (5) to surround the suspension bolt (6). An insertion space (6a) is formed that surrounds.
然る後、図２、３のように取付金具(1)に装着された脱落防止金具(10)の上下両側においてナット(20)(21)を締め、天井の所定高さ位置に空調室内機(M)を吊設する。 After that, as shown in FIGS. 2 and 3, the nuts (20) and (21) are tightened on both the upper and lower sides of the drop-off prevention bracket (10) mounted on the mounting bracket (1), and the air conditioning indoor unit is placed at a predetermined height on the ceiling. Suspend (M).
この状態で前述のような地震に見舞われ、空調室内機(M)が大きく揺れて吊りボルト(6)が取付金具(1)の取付用切欠溝(5)の開口側に向かって移動しようとしても、脱落防止金具(10)は取付金具(1)の金具本体(2)と折曲片(4)との間にて金具本体(2)と折曲片(4)との間隔にほぼ等しい幅で装着されており、しかも吊りボルト(6)が脱落防止金具(10)の交差片(12)にて閉塞された挿通空間(6a)内に挿通されているため、仮に交差片(12)に吊りボルト(6)が強圧して脱落防止金具(10)を前記取付用切欠溝(5)の開口側に向かって移動させようとしてもこの時、交差片(12)が折曲片(4)に当接して脱落防止金具(10)のそれ以上の移動を阻止する。これにより確実に吊りボルト(6)の取付金具(1)からの脱落を確実に防止することができる。また、突起(16)が取付用切欠溝(5)内に嵌り込んでおり、且つ、上下からナット(20)(21)によって挟み込まれているので、前記地震の入力時でも脱落防止金具(10)が取付金具(1)から脱落するようなことがない。 In this state, the above-mentioned earthquake was hit, and the air conditioning indoor unit (M) was greatly shaken and the suspension bolt (6) tried to move toward the opening side of the mounting groove (5) of the mounting bracket (1). However, the drop-off prevention bracket (10) is approximately equal to the distance between the bracket body (2) and the bent piece (4) between the bracket body (2) and the bent piece (4) of the mounting bracket (1). Since the hanging bolt (6) is inserted in the insertion space (6a) closed by the cross piece (12) of the drop-off prevention metal fitting (10), the cross piece (12) is temporarily installed. Even if the suspension bolt (6) is strongly pressed to move the drop-off prevention metal fitting (10) toward the opening side of the mounting notch groove (5), the cross piece (12) is bent at this time (4 ) To prevent further movement of the fall-off prevention metal fitting (10). As a result, it is possible to reliably prevent the suspension bolt (6) from falling off the mounting bracket (1). Further, since the projection (16) is fitted in the mounting notch groove (5) and is sandwiched by the nuts (20) (21) from above and below, the drop-off prevention bracket (10 ) Will not fall off the mounting bracket (1).
次に、本発明の第２実施例（図７〜図１１）について説明する。第２実施例の説明において、第１実施例と同じような内容は煩雑さを避けるため、第１実施例の説明を援用してその記載を省略する。この場合は、第１実施例の本体プレート(11)の他端部分を折り返した形状のもので、この折り返し部分が本体プレート(11)とで水平取付片(3)をその上下から挟持する挟持片(13)である。挟持片(13)と本体プレート(11)との間に形成された隙間(S)は水平取付片(3)の板厚に対して同じかやや大きい或いはやや狭い間隔に形成されており、挟持片(13)及び本体プレート(11)は材質的には弾発性を有するものが使用されている。 Next, a second embodiment (FIGS. 7 to 11) of the present invention will be described. In the description of the second embodiment, the description similar to that of the first embodiment is omitted from the description of the first embodiment in order to avoid complexity. In this case, the other end portion of the body plate (11) of the first embodiment is folded, and the folded portion sandwiches the horizontal mounting piece (3) from the upper and lower sides with the body plate (11). It is a piece (13). The gap (S) formed between the clamping piece (13) and the body plate (11) is formed at the same, slightly larger or slightly narrower spacing than the plate thickness of the horizontal mounting piece (3). The piece (13) and the body plate (11) are made of elastic material.
そして、挟持片(13)が本体プレート(11)と同程度の幅とした時は固定用切欠溝(14)と同じ形状のもう一つの固定用切欠溝(15)が対向する位置に形成されることになる。また、挟持片(13)は本体プレート(11)より若干短く、本体プレート(11)の挟持片(13)より長い部分が水平取付片(3)への挿入のガイドとなる。 When the sandwiching piece (13) has the same width as that of the main body plate (11), another fixing notch groove (15) having the same shape as the fixing notch groove (14) is formed at the facing position. Will be. Further, the sandwiching piece (13) is slightly shorter than the main body plate (11), and a portion longer than the sandwiching piece (13) of the main body plate (11) serves as a guide for insertion into the horizontal mounting piece (3).
勿論、挟持片(13)の形状は上記のように本体プレート(11)と同幅にする必要はなく、図示しないが挟持片(13)側又は反対側の片だけに対向するように１本だけ設けることも可能である。 Of course, the shape of the sandwiching piece (13) does not need to be the same width as the main body plate (11) as described above, but it is not shown in the figure, but only one piece faces the sandwiching piece (13) side or the opposite side. It is also possible to provide only.
しかして、空調室内機(M)を吊りボルト(6)に取り付けるに当っては、図１と同様に金具本体(2)の水平取付片(3)の側方から挿入する。然る後、図７のように取付金具(1)に装着された脱落防止金具(10)の上下両側においてナット(20)(21)を締め天井の所定高さ位置に空調室内機(M)を吊設する。第２実施例の場合は、挟持片(13)が存在するので、上のナット(21)がなくとも脱落防止金具(10)自体が水平取付片(3)に取り付いているので、下側のナット(20)だけでもよい。 Thus, when attaching the air conditioning indoor unit (M) to the suspension bolt (6), it is inserted from the side of the horizontal mounting piece (3) of the metal fitting body (2) as in FIG. After that, as shown in FIG. 7, the nuts (20) and (21) are tightened on the upper and lower sides of the drop-off prevention bracket (10) mounted on the mounting bracket (1), and the air conditioning indoor unit (M) is placed at a predetermined height on the ceiling. Suspend. In the case of the second embodiment, since the clamping piece (13) is present, the drop-off prevention bracket (10) itself is attached to the horizontal mounting piece (3) without the upper nut (21).

After that, as shown in FIG. 12, the drop-off prevention fitting (10) is attached to the attachment fitting (1) with the bolt (40) and the nut (41). In this state, lift the air conditioning indoor unit (M) to the ceiling height, and lower the lower end of the suspension bolt (6) suspended from the ceiling into the through hole (37) from the upper rubber tube (33) to the washer (36). Insert and suspend the bottom end of the suspension bolt (6) with the nut (37).
もう一つのやりかたとして、天井から吊るされた吊りボルト(6)に先に吊りボルト装着具(30)を取り付けておいて、その後、第２実施例の取付方法に従って、空調室内機(M)の取付金具(1)に脱落防止金具(10)を装着するようにしてもよい。 Another way to do this is to first attach the suspension bolt mounting tool (30) to the suspension bolt (6) suspended from the ceiling. Then, according to the mounting method of the second embodiment, the air conditioning indoor unit (M) The drop-off prevention bracket (10) may be attached to the mounting bracket (1).
この状態で前述のような地震に見舞われても第１実施例と同様或いは挟持片(13)が存在する分だけナット(20)(21)が緩んでも脱落防止金具(10)自体が水平取付片(3)に取り付いているので、より確実に吊りボルト(6)の取付金具(1)からの脱落を確実に防止することができる。 Even if an earthquake such as the one described above occurs in this state, the drop-off prevention bracket (10) itself is mounted horizontally even if the nuts (20) (21) are loosened as much as the first embodiment or as much as the clamping piece (13) exists. Since it is attached to the piece (3), it is possible to reliably prevent the suspension bolt (6) from falling off the mounting bracket (1).
