Description

本発明は、例えば浴室などの天井に、乾燥機の室内機などの吊下げ対象物を吊り下げる際に用いると便利な補助装置に関する。   The present invention relates to an auxiliary device that is convenient to use when hanging a suspended object such as an indoor unit of a dryer on a ceiling such as a bathroom.

上述した乾燥機の室内機を浴室の天井に取付けるには、従来当初、天井の複数箇所に吊り下げたボルトにナットを螺着し、室内機にボルトに対応する数、位置で取付けた固定金具を、前記ナットにより下側から支持する方式が採用されていた。   To attach the above-described dryer indoor unit to the ceiling of the bathroom, conventionally, nuts are screwed onto bolts suspended at multiple locations on the ceiling, and the fixing brackets are attached to the indoor unit in the number and position corresponding to the bolts. Is supported from below by the nut.

ところで、上述した吊り下げ方式では、重量のある室内機を天井近くまで持ち上げつつナットを取付ける必要があり、一人での取付けが困難で作業性が悪いという難点がある。   By the way, in the above-described suspension system, it is necessary to attach a nut while lifting a heavy indoor unit to the vicinity of the ceiling, and there is a problem that it is difficult to mount alone and workability is poor.

そこで、近年においては、作業性を改善すべく、ナットの代わりに別機構の支持装置を用いて乾燥機の室内機などを天井に取付けることが行われており、その支持装置として、図１２及び図１３に示す構成のものが知られている（例えば、特許文献１参照）。   Therefore, in recent years, in order to improve workability, it has been performed to attach an indoor unit or the like of a dryer to a ceiling using a support device of another mechanism instead of a nut. The thing of the structure shown in FIG. 13 is known (for example, refer patent document 1).

この支持装置は、天井から垂設したボルト１０４に、室内機１０２に設けたボルト孔１０３を挿通して支持するもので、水平な枢支ピン１１１回りに揺動可能な一対の係止部１０６、１０６が上下２段設けられ、天井から垂設したボルト１０４に前述の係止部１０６が係止する状態と、付勢バネ１１４の付勢力に抗して解除機構１０７を内側に押し込むと各係止部１０６のボルト１０４に対する係止が解除される状態とになる構成となっている。なお、係止部１０６は二分割構造となっていて、係止状態のとき、係止部１０６の先端に形成された雌ネジ面１０６ａがボルト１０４に噛合するようになっている。   This support device supports a bolt 104 suspended from the ceiling by inserting a bolt hole 103 provided in the indoor unit 102, and a pair of locking portions 106 swingable around a horizontal pivot pin 111. , 106 are provided in two upper and lower stages, and when the above-described locking portion 106 is locked to the bolt 104 suspended from the ceiling, and when the release mechanism 107 is pushed inward against the biasing force of the biasing spring 114, In this configuration, the locking of the locking portion 106 with respect to the bolt 104 is released. Note that the locking portion 106 has a two-part structure, and when locked, a female thread surface 106 a formed at the tip of the locking portion 106 is engaged with the bolt 104.

よって、付勢バネ１１４の付勢力により解除機構１０７を外側に押し出すと、ボルト１０４に係止部１０６が係止して室内機１０２の落下を防止し、付勢バネ１１４の付勢力に抗して解除機構１０７を内側に押し込むと支持装置を取り外すことができる。これにより、一人でも取付けが可能になる。
特開平８−１７８４１３号公報 Therefore, when the release mechanism 107 is pushed outward by the urging force of the urging spring 114, the locking portion 106 is locked to the bolt 104 to prevent the indoor unit 102 from falling and against the urging force of the urging spring 114. When the release mechanism 107 is pushed inward, the support device can be removed. Thereby, even one person can be attached.

しかしながら、上述した従来の支持装置による場合には、室内機を支持する間ずっとボルトに取付けておく必要があるため、ナットに比べて大幅にコストが上昇するという難点があった。そこで、このように室内機を取付けた後も取外しができない支持装置に代えて、従来同様にボルトへのナット装着により吊下げ対象物を支持して仮止めすることができ、しかも取外しができる補助装置の出現が期待されていた。   However, in the case of using the above-described conventional support device, it is necessary to attach the bolt to the bolt all the time while supporting the indoor unit. Therefore, instead of a support device that cannot be removed even after the indoor unit is installed in this way, an auxiliary object that can be temporarily fixed by supporting a suspended object by attaching a nut to a bolt as in the prior art, and that can be removed. The appearance of the device was expected.

本発明は、このような従来技術の課題を解決するためになされたものであり、ボルトへのナット装着により吊下げ対象物を支持して仮止めすることができ、しかも取外しができる補助装置を提供することを目的とする。   The present invention has been made in order to solve the above-described problems of the prior art.

Yes. Prior to attaching the indoor unit 30 to the ceiling 35, a first nut 37 for suspending the auxiliary device is screwed to the bolt 36. Further, the indoor unit 30 is temporarily fixed by passing the through hole 32 of the metal fitting 31 through the bolt 36 and screwing the second nut 38 for fixing to the lower side of the metal fitting 31.

一方、図１等に示される本実施形態の補助装置１は、第２ナット３８により金具３１をボルト３６に仮止めする際に、第１ナット３７に吊下げられ、仮止め後に取外されるものである。第１ナット３７及び第２ナット３８としては、本実施形態では一般的な六角ナットを用いるものとして説明するが、四角や八角ナットなどを使用してもよい。   On the other hand, the auxiliary device 1 of the present embodiment shown in FIG. 1 and the like is suspended by the first nut 37 when the metal fitting 31 is temporarily fixed to the bolt 36 by the second nut 38, and is removed after temporary fixing. Is. As the first nut 37 and the second nut 38, in the present embodiment, a general hexagon nut is used, but a square or an octagon nut may be used.

この補助装置１の構成は、以下の通りである。即ち、補助装置１は、上部に設けられた吊下げ部２と、吊下げ部２の下側に設けられた一対の揺動部材１０、２０とを備える。   The configuration of the auxiliary device 1 is as follows. That is, the auxiliary device 1 includes a hanging part 2 provided on the upper part and a pair of swinging members 10 and 20 provided on the lower side of the hanging part 2.

吊下げ部２は、例えば金属製の概略矩形状をした吊下げ部本体３と、固定用のネジ４とを有する。ネジ４としては、図示例では蝶ネジを使用している。吊下げ部本体３は、一側面３ａと、この一側面３ａに繋がる上面３ｂおよび下面３ｃとに開口５ａ、５ｂ、５ｃを有する横向き凹部５を有し、この横向き凹部５は前記ボルト３６を挿通させるために形成されていて、一側面３ａの開口５ａはボルト３６の直径よりも少し大きく、第１ナット３７の二面幅よりも狭い幅寸法で上下方向に形成されている。上面３ｂの開口５ｂは開口５ａの幅寸法と同じ幅で内奥部が半円状となったＵ字状に形成されている。下面３ｃの開口５ｃは、一側面３ａ側を開口５ａと同じ幅寸法とし、内奥部が開口５ａの幅寸法よりも広い概略Ｃ字状に形成されており、開口５ｃの内奥部は開口５ａの幅寸法の半分よりも十分に大きい曲率半径であって第１ナット３７が入る大きさに設定されている。この概略Ｃ字状の開口５ｃは下面３ｃから半分以上上側の部位までの範囲に設けられており、横向き凹部５の内奥部は、上側にボルト３６を挿通させ得る寸法の狭幅部が形成され、下側に第１ナット３７が入り得る広幅部が形成され、これら狭幅部と広幅部との境界に段付き部５ｄが設けられている。また、横向き凹部５の内奥部には、ネジ４の先端４ａが突出するようになっている（図２、図４参照）。なお、一側面３ａの開口５ａに関しては、図示例では上から下まで同じ開口幅（ボルト３６の直径よりも少し大きく、第１ナット３７の二面幅よりも狭い幅寸法）としているが、段付き部５ｄよりも下側の箇所にあっては、第１ナット３７が抜け落ちないように、第１ナット３７の二面幅よりも小さくなっていてもよい。つまり、一側面３ａの開口５ａは、段付き部５ｄよりも上側と下側とで開口幅が異なっていてもよい。   The hanging part 2 includes a hanging part main body 3 having a substantially rectangular shape made of metal, for example, and a fixing screw 4. As the screw 4, a thumbscrew is used in the illustrated example. The hanging part main body 3 has a lateral recess 5 having openings 5a, 5b, 5c on one side surface 3a and upper and lower surfaces 3b and 3c connected to the one side surface 3a. The lateral recess 5 is inserted through the bolt 36. The opening 5a of the one side surface 3a is formed in the vertical direction with a width dimension that is slightly larger than the diameter of the bolt 36 and narrower than the two-surface width of the first nut 37. The opening 5b of the upper surface 3b is formed in a U shape having the same width as the opening 5a and a semicircular inner part. The opening 5c of the lower surface 3c has the same width dimension as the opening 5a on one side surface 3a side, and is formed in a substantially C shape with the inner back part wider than the width dimension of the opening 5a. The radius of curvature is sufficiently larger than half of the width dimension of 5a, and the first nut 37 can be inserted. The substantially C-shaped opening 5c is provided in a range from the lower surface 3c to a portion more than half above, and the inner back portion of the laterally-facing recess portion 5 is formed with a narrow-width portion having a dimension capable of inserting the bolt 36 on the upper side.

The opening 5a on the one side surface 3a has the same opening width from the top to the bottom (a width dimension that is slightly larger than the diameter of the bolt 36 and narrower than the two-surface width of the first nut 37). In a location below the attaching portion 5d, the width of the first nut 37 may be smaller than the two-surface width so that the first nut 37 does not fall off. That is, the opening width of the opening 5a of the one side surface 3a may be different between the upper side and the lower side of the stepped portion 5d.

よって、垂下状態のボルト３６に対して一側面３ａの開口５ａを一致させ、かつ下面３ｃを第１ナット３７よりも高くして、横向き凹部５にボルト３６を挿入させ、その後に補助装置１を少し降下させると、段付き部５ｄが第１ナット３７で支持されることになり、吊下げ部２が第１ナット３７に吊り下げられる。そして、ネジ４を締めると、ネジ４の先端４ａが、例えば第１ナット３７の側面に当接し、吊下げ部２がボルト３６に固定される。   Therefore, the opening 5a of the one side surface 3a is made to coincide with the suspended bolt 36, and the lower surface 3c is made higher than the first nut 37 so that the bolt 36 is inserted into the laterally recessed portion 5, and then the auxiliary device 1 is installed. When lowered slightly, the stepped portion 5 d is supported by the first nut 37, and the suspended portion 2 is suspended by the first nut 37. When the screw 4 is tightened, the tip 4 a of the screw 4 comes into contact with the side surface of the first nut 37, for example, and the hanging portion 2 is fixed to the bolt 36.

Therefore, the swinging lower portions 12 and 22 can swing in the direction of the white arrow around the swinging shaft portions 11a and 21a in the hinges 11 and 21, and are substantially below the swinging shaft portions 11a and 21a. The upper end of the swinging part is attached to the hanging part 2. The outer plate-like pieces 12b and 22b and the inner plate-like pieces 12c and 22c are connected by connecting pieces 12g and 22g.

内側の板状片１２ｃ、２２ｃは、無負荷状態において、上端が互いに最接近する接近部１２ｄ、２２ｄとなっていて、内側の両板状片１２ｃ、２２ｃの間の間隔は、下端の折り曲げ部１２ａ、２２ａから接近部１２ｄ、２２ｄに近づく程に狭くなるように形成されている。また、接近部１２ｄ、２２ｄには、上向きに突出した係止部１２ｅ、２２ｅが設けられている。この係止部１２ｅ、２２ｅは、前記取付用金具３１の貫通孔３２を被係止部として係止するものである。各係止部１２ｅ、２２ｅのそれぞれは、開口部１２ｆ、２２ｆを挟んで２つに分離した状態で設けられている。開口部１２ｆは内側の板状片１２ｃと連結片１２ｇとにそれぞれ形成され、開口部２２ｆは内側の板状片２２ｃと連結片２２ｇとにそれぞれ形成されている。これら開口部１２ｆ、２２ｆは、後述するように吊下げ部２の第１ナット３７による吊下げを解除した後に吊下げ部２を降下させることに伴って、第２ナット３８を抜けさせ得る抜け孔として機能するものである。   The inner plate-like pieces 12c and 22c are approaching portions 12d and 22d whose upper ends are closest to each other in the no-load state, and the interval between the inner plate-like pieces 12c and 22c is the bent portion at the lower end. It is formed so that it becomes so narrow that it approaches 12d and 22d from 12a and 22a. The approaching portions 12d and 22d are provided with locking portions 12e and 22e protruding upward. The locking portions 12e and 22e are to lock the through hole 32 of the mounting bracket 31 as a locked portion. Each of the locking portions 12e and 22e is provided in a state of being separated into two with the openings 12f and 22f interposed therebetween. The opening 12f is formed in the inner plate-like piece 12c and the connecting piece 12g, respectively, and the opening 22f is formed in the inner plate-like piece 22c and the connecting piece 22g, respectively. These openings 12f and 22f are holes through which the second nut 38 can be removed when the suspension 2 is lowered after the suspension of the suspension 2 by the first nut 37 is released, as will be described later. It functions as.

次に、このように構成された補助装置１を用いて、図５に示すように天井３５から垂下させたボルト３６に、室内機３０に取付けた取付用金具３１を支持するように第２ナット３８を螺着して、金具３１をボルト３６に仮止めする工程を、図６〜図８に基づき説明する。なお、図６と図８は、方向を９０゜ずらして表した図である。   Next, by using the auxiliary device 1 configured as described above, the second nut so as to support the mounting bracket 31 attached to the indoor unit 30 on the bolt 36 suspended from the ceiling 35 as shown in FIG. A process of screwing 38 and temporarily fixing the metal fitting 31 to the bolt 36 will be described with reference to FIGS. 6 and 8 are diagrams showing the directions shifted by 90 °.

図６（ａ）に示すように、天井３５から垂下させたボルト３６に第１ナット３７を螺着する。次に、図６（ｂ）に示すように、補助装置１を手に持って第１ナット３７に吊り下げる。つまり、ボルト３６に対して一側面（３ａ）の開口（５ａ）を一致させ、かつ下面３ｃを第１ナット３７よりも高くして、補助装置１を水平移動させて横向き凹部（５）にボルト３６を挿入させる。その後、図６（ｃ）に示すように、補助装置１を少し降下させると、段付き部（５ｄ）が第１ナット３７で支持される。このとき、前述したように一側面（３ａ）の開口（５ａ）の開口幅が第１ナット３７の二面幅よりも狭く形成されているので、第１ナット３７から吊下げ部２が外れることがない。これにより補助装置１から手を離すことが可能になる。その後、図６（ｄ）に示すように、揺動下部１２、２２の一方または両方を広げ、前記抜け孔（開口部）１２ｆ、２２ｆにボルト３６を入れるとともに固定用のネジ４を締める。   As shown in FIG. 6A, a first nut 37 is screwed onto a bolt 36 suspended from the ceiling 35. Next, as shown in FIG. 6B, the auxiliary device 1 is held in the hand and suspended from the first nut 37. That is, the opening (5a) of one side surface (3a) is made to coincide with the bolt 36, and the lower surface 3c is made higher than the first nut 37, so that the auxiliary device 1 is moved horizontally, and the bolt is placed in the lateral recess (5). 36 is inserted. Thereafter, as shown in FIG. 6C, when the auxiliary device 1 is slightly lowered, the stepped portion (5 d) is supported by the first nut 37. At this time, as described above, the opening width of the opening (5a) of the one side surface (3a) is formed to be narrower than the two surface widths of the first nut 37, so that the suspended portion 2 is detached from the first nut 37. There is no. As a result, it is possible to release the hand from the auxiliary device 1. Thereafter, as shown in FIG. 6 (d), one or both of the swinging lower portions 12 and 22 are expanded, bolts 36 are inserted into the through holes (openings) 12f and 22f, and the fixing screws 4 are tightened.

以上の補助装置１のボルト３６への取付けを、４本のボルト３６のそれぞれに対して行う。   The attachment of the auxiliary device 1 to the bolt 36 is performed for each of the four bolts 36.

次に、図６（ｅ）に示すように、室内機３０を手で持ち上げて、取付用金具３１の貫通孔３２にボルト３６の下端を通し、金具３１を徐々に上昇させる。このとき、内側の両板状片１２ｃ、２２ｃの間の間隔が、下端の折り曲げ部１２ａ、２２ａから接近部１２ｄ、２２ｄに近づく程に狭くなるように形成されているので、図６（ｆ）に示すように、金具３１の上昇に伴って接近部１２ｄと接近部２２ｄとの間隔が広くなっていき、図６（ｇ）に示すように、両接近部１２ｄ、２２ｄの間を金具３１が下側から上側へと通過する。このとき、ネジ４により補助装置１が第１ナット３７に固定されているので、金具３１を上昇させる際に補助装置１が第１ナット３７から外れることがない。   Next, as shown in FIG. 6E, the indoor unit 30 is lifted by hand, the lower end of the bolt 36 is passed through the through hole 32 of the mounting bracket 31, and the bracket 31 is gradually raised. At this time, the interval between the inner plate-like pieces 12c and 22c is formed so as to become narrower toward the approaching parts 12d and 22d from the bent parts 12a and 22a at the lower end, so that FIG. As shown in FIG. 6, the distance between the approaching portion 12d and the approaching portion 22d increases as the fitting 31 rises, and the fitting 31 is placed between the approaching portions 12d and 22d as shown in FIG. Pass from the bottom to the top. At this time, since the auxiliary device 1 is fixed to the first nut 37 by the screw 4, the auxiliary device 1 is not detached from the first nut 37 when the metal fitting 31 is raised.

そして、金具３１の貫通孔３２が接近部１２ｄ、２２ｄよりも上方位置に達すると、図６（ｈ）に示すように、金具３１を降下させる。このとき、両揺動部材１０、２０は、自重により接近部１２ｄ、２２ｄ同士が接近した状態になっているので、金具３１の降下により、金具３１の被係止部としての貫通孔３２が、係止部１２ｅ、２２ｅに係止される。図７は貫通孔３２が係止部１２ｅ、２２ｅに係止された状態を示す斜視図である。これにより金具３１が補助装置１により保持される。この保持操作は、４個の金具３１の全てを同時に各補助装置１に対して保持させるように行ってもよく、或いは１つずつ、或いは２または３つを同時に行ってもよい。   Then, when the through hole 32 of the metal fitting 31 reaches a position above the approaching portions 12d and 22d, the metal fitting 31 is lowered as shown in FIG. 6 (h). At this time, since both the swinging members 10 and 20 are in a state where the approaching portions 12d and 22d approach each other due to their own weight, the through hole 32 as the locked portion of the metal fitting 31 is lowered by the lowering of the metal fitting 31. Locked to the locking portions 12e and 22e. FIG. 7 is a perspective view showing a state in which the through hole 32 is locked to the locking portions 12e and 22e. Thereby, the metal fitting 31 is held by the auxiliary device 1. This holding operation may be performed so that all of the four metal fittings 31 are held simultaneously with respect to each auxiliary device 1, or may be performed one by one, or two or three at the same time.

この保持状態において、図６（ｉ）に示すように、各ボルト３６にそれぞれ下側から固定用の第２ナット３８を螺着する。よって、貫通孔３２は、係止部１２ｅ、２２ｅに係止される被係止部を兼ねるため、被係止部を別途設ける必要性を無くすることができる。   In this holding state, as shown in FIG. 6 (i), a second nut 38 for fixing is screwed to each bolt 36 from below. Therefore, since the through-hole 32 also serves as a locked portion locked to the locking portions 12e and 22e, it is possible to eliminate the necessity of separately providing the locked portion.

その後、補助装置１における固定用のネジ４を弛めた後、図８（ａ）に示すように室内機３０と一緒に補助装置１を持ち上げ、続いて、図８（ｂ）に示すように補助装置１を傾けて横向き凹部（５）を介してボルト３６から補助装置１を取外し、図８（ｃ）に示すように補助装置１を降下させる。この降下に際し、抜き孔（開口部）１２ｆ、２２ｆから第２ナット３８を下側へ挿通させる。すると、貫通孔３２から係止部１２ｅ、２２ｅが抜け出して、図８（ｄ）に示すように第２ナット３８により金具３１がボルト３６に仮止めされる。この操作は、各補助装置１毎に別々に行うのが好ましいが、同時に行ってもよい。   Thereafter, after loosening the fixing screw 4 in the auxiliary device 1, the auxiliary device 1 is lifted together with the indoor unit 30 as shown in FIG. 8A, and subsequently, as shown in FIG. 8B. The auxiliary device 1 is tilted, the auxiliary device 1 is removed from the bolt 36 through the lateral recess (5), and the auxiliary device 1 is lowered as shown in FIG. At the time of this lowering, the second nut 38 is inserted downward from the through holes (openings) 12f and 22f. Then, the locking portions 12e and 22e come out from the through hole 32, and the metal fitting 31 is temporarily fixed to the bolt 36 by the second nut 38 as shown in FIG. This operation is preferably performed separately for each auxiliary device 1, but may be performed simultaneously.

よって、本実施形態の補助装置１による場合には、ボルト３６への第２ナット３８の装着により室内機３０を支持して仮止めすることができ、しかも仮止めに際してボルト３６からの取外しができる。   Therefore, in the case of the auxiliary device 1 of the present embodiment, the indoor unit 30 can be supported and temporarily fixed by attaching the second nut 38 to the bolt 36, and can be removed from the bolt 36 at the time of temporary fixing. .

また、本実施形態では、無負荷状態で、両揺動部材１０、２０における内側の両板状片１２ｃ、２２ｃの間の間隔が、下端の折り曲げ部１２ａ、２２ａから接近部１２ｄ、２２ｄに近づく程に狭くなるように形成されているので、金具３１を下側から接近部１２ｄ、２２ｄへ向けて上昇させると、自然に両揺動部材１０、２０がその下端を開くように揺動するので、一対の揺動部材１０、２０に対して何ら手で操作をすることなく、金具３１を接近部１２ｄ、２２ｄの上方まで上昇させ得る。   In the present embodiment, in the no-load state, the distance between the inner plate-like pieces 12c and 22c in the swing members 10 and 20 approaches the approaching portions 12d and 22d from the bent portions 12a and 22a at the lower end. Since the metal fitting 31 is raised from the lower side toward the approaching portions 12d and 22d, both the swinging members 10 and 20 swing naturally so as to open their lower ends. The metal fitting 31 can be raised above the approaching portions 12d and 22d without any manual operation with respect to the pair of swinging members 10 and 20.

なお、上述した実施形態では吊下げ部２として、開口５ｃから第１ナット３７を入れ、段付き部５ｄが第１ナット３７で下側から支持されるとともに、ネジ４により第１ナット３７に固定される構成としているが、本発明はこれに限らず、他の構成としてもよい。   In the above-described embodiment, the first nut 37 is inserted from the opening 5 c as the hanging portion 2, and the stepped portion 5 d is supported from the lower side by the first nut 37 and fixed to the first nut 37 by the screw 4. However, the present invention is not limited to this, and other configurations may be used.
