Was able to provide.

以下、図面に基づき本願発明の実施の形態の一例をとりあげて説明する。図１は、本例のハンガー装置の概略を示し、図２は本例のリングを示し、図３は本例のリングと吊下紐とキャップとを示す。   Hereinafter, an example of an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows an outline of the hanger device of this example, FIG. 2 shows a ring of this example, and FIG. 3 shows a ring, a hanging string and a cap of this example.

図１に示すように、本例のハンガー装置は、本体部２、支持部としての吊下紐３、被支持部としてのリング４とを備えたものとされている。   As shown in FIG. 1, the hanger apparatus of this example is provided with the main-body part 2, the hanging string 3 as a support part, and the ring 4 as a supported part.

本体部２は、家屋などの天井Ｃにねじ止めなどによって取り付けられる箱状の物体である。この本体部２の内部には吊下紐３が収納可能とされている。この吊下紐３の収納は、本体部２の内部に設けられた巻取り機構によってなされ(図示しない）、リング４を使用する際には、吊下紐３を本体部２から任意の長さ分引き出した状態で保持することができ、使用後は再び本体部１の内部に収納することができる。   The main body 2 is a box-like object attached to a ceiling C of a house or the like by screwing or the like. A hanging string 3 can be stored inside the main body 2. The suspension strap 3 is stored by a winding mechanism (not shown) provided inside the main body 2 (not shown), and when the ring 4 is used, the suspension strap 3 can be moved from the main body 2 to an arbitrary length. It can be held in a state of being pulled out and can be stored in the main body 1 again after use.

吊下紐３は、少なくとも下端部分が本体部２に対して昇降自在とされたものである。本例ではステンレスワイヤーが用いられているが、合成樹脂製のロープや鎖など、本体部に収納可能な可撓性を有する長尺体であれば、種々の素材での実施が可能である。また、吊下紐３の径寸法についても、本例では常に一定のものとされているが、例えば吊下げられた状態において、上方に向かう程太くなるテーパ状であっても良い。   The hanging string 3 is configured such that at least a lower end portion can be raised and lowered with respect to the main body 2. In this example, stainless steel wire is used, but various materials can be used as long as it is a flexible long body that can be stored in the main body, such as a rope or chain made of synthetic resin. Also, the diameter of the hanging string 3 is always constant in this example, but for example, in a suspended state, it may be tapered so as to increase in thickness.

本例では、吊下紐３の下端に球状の拡大部３１が一体に設けられている。この拡大部３１は、金属球がかしめられたものであるが、溶接などの他の手段で接合されたものであっても良い。また、単に吊下紐３の結び目や、吊下紐３の下端部分を折り曲げ、針金や帯金を巻きつけたものであっても良い。形態についても球状に限られず、円錐状や円柱状としても良い。つまり、吊下紐３の直径を、後述する可破壊部５の貫通孔５２ａよりも大きく変形させたものであれば、種々の形態での実施が可能である。なお、吊下紐３の拡大部３１のすぐ上の部分を、便宜上、挿通部３２と称して以下説明する。   In this example, a spherical enlarged portion 31 is integrally provided at the lower end of the hanging string 3. The enlarged portion 31 is formed by caulking a metal ball, but may be joined by other means such as welding. Alternatively, the knot of the hanging string 3 or the lower end portion of the hanging string 3 may be bent and wound with a wire or a band. The form is not limited to a spherical shape, and may be a conical shape or a cylindrical shape. That is, various forms can be implemented as long as the diameter of the hanging cord 3 is deformed larger than a through hole 52a of the breakable portion 5 described later. In addition, the part immediately above the expansion part 31 of the hanging string 3 is called the insertion part 32 for convenience, and is demonstrated below.

リング４は、吊下紐３の下端部分に吊下げられたものである。これは、物干し器などの被吊下体を吊下げることのできる部分であって、本例では円環状とされている。このリング４の形態についても本例のものに限定されるものではなく、多角形など、他形状の環状のものや、フック状のもの、棒状体など、種々の形態で実施が可能である。   The ring 4 is suspended from the lower end portion of the suspension string 3. This is a portion where a suspended body such as a clothes dryer can be suspended, and is an annular shape in this example. The form of the ring 4 is not limited to the one in this example, and can be implemented in various forms such as a polygonal shape such as an annular shape, a hook shape, and a rod-like body.

本例のハンガー装置１では、図２に示すように、リング４の上端に一体に可破壊部５が設けられる。この可破壊部５は中空の円筒状体であり、図示したように、内部に中空部５１を有し、下端がリング本体４１と連続している。
この可破壊部５の中空部５１を囲む部分の一部である上端部５２には、少なくともこの上端部５２の上面中心を通るようにスリット状の貫通孔５２ａが設けられている。そして、可破壊部５の側方部５３には、拡大部３１を中空部５１に導入可能な寸法を有する開口部５３ａが形成されている。
上記の貫通孔５２ａは、少なくともスリット形状の一端側が可破壊部５の側方部５３に開口され、開口部５３ａと連続するものであって、このスリット形状の幅寸法は、吊下紐３のうち挿通部３２が通過可能なものとされている。これにより、吊下紐３の拡大部３１を開口部５３ａから中空部５１に導入し、これと同時に、吊下紐３の挿通部３２を貫通孔５２ａに通すことで、可破壊部５に拡大部３１を配することができ、この状態で、図３（Ａ）に示すように、拡大部３１と可破壊部５の上端部内面５２ｂが当接することで、引張力を吊下紐３から可破壊部５を介してリング４に伝達できる。 In the hanger device 1 of this example, as shown in FIG. 2, the breakable part 5 is integrally provided at the upper end of the ring 4. The destructible portion 5 is a hollow cylindrical body, and has a hollow portion 51 inside and has a lower end continuous with the ring body 41 as illustrated.
A slit-like through-hole 52 a is provided in the upper end portion 52, which is a part of the portion surrounding the hollow portion 51 of the destructible portion 5, so as to pass at least the center of the upper surface of the upper end portion 52. An opening 53 a having a dimension capable of introducing the enlarged portion 31 into the hollow portion 51 is formed in the side portion 53 of the breakable portion 5.
The through-hole 52a has at least one slit-shaped one end opened to the side portion 53 of the breakable portion 5 and is continuous with the opening 53a. Of these, the insertion part 32 can pass therethrough. Thereby, the expansion part 31 of the hanging string 3 is introduced into the hollow part 51 from the opening 53a, and at the same time, the insertion part 32 of the hanging string 3 is passed through the through hole 52a, thereby expanding to the breakable part 5. In this state, as shown in FIG. 3 (A), the enlarged portion 31 and the upper end inner surface 52b of the destructible portion 5 come into contact with each other, so that the tensile force can be It can be transmitted to the ring 4 via the breakable part 5.

一方、上記の引張力が増大した際には、拡大部３１が可破壊部５の上端部内面５２ｂを押圧することにより、可破壊部５が破壊される。つまり、拡大部３１によって貫通孔５２ａが押し広げられる。そして、貫通孔５２ａの、広げられた状態の大きさが拡大部３１の大きさを超えた場合、拡大部が貫通孔５２ａを通過し、可破壊部５と拡大部３１とが分離する。   On the other hand, when the tensile force is increased, the demagnifying part 5 is destroyed by the enlarged part 31 pressing the upper end part inner surface 52 b of the destructible part 5. That is, the through hole 52 a is pushed and expanded by the enlarged portion 31. And when the magnitude | size of the expanded state of the through-hole 52a exceeds the magnitude | size of the enlarged part 31, an enlarged part passes the through-hole 52a, and the destructible part 5 and the enlarged part 31 isolate | separate.

この、拡大部３１が通り抜けてしまう程に貫通孔５２ａが広がる引張力に合わせて、可破壊部５の上端部５２の厚み、貫通孔５２ａの形状、拡大部３１の形状を設定することにより、所望の引張力で可破壊部５が破壊されるようにでき、ハンガー装置１の他の部分が破壊されたり、本体部２が天井Ｃから落下してしまう前に、可破壊部５を備えたリング４のみを落下させることができ、過負荷時の被害を最小限にとどめることができる。
また、破壊されるのが、ハンガー装置１の下方に位置するリング部４のみであることより、その後の修理の際にあっても、本体部２の分解が不要で、容易に作業できる。また、リング部４はハンガー装置１のうちで、比較的安価な部品であるため、経済的ロスも最小限とすることができる。 By setting the thickness of the upper end portion 52 of the breakable portion 5, the shape of the through hole 52 a, and the shape of the enlarged portion 31 according to the tensile force that the through hole 52 a spreads as the enlarged portion 31 passes through, The destructible part 5 can be destroyed with a desired tensile force, and the other part of the hanger device 1 is destroyed or the destructible part 5 is provided before the main body part 2 falls from the ceiling C. Only the ring 4 can be dropped, and damage during overload can be minimized.
In addition, since only the ring portion 4 positioned below the hanger device 1 is destroyed, the main body portion 2 is not required to be disassembled even during subsequent repairs and can be easily operated. Moreover, since the ring part 4 is a comparatively cheap part in the hanger apparatus 1, economical loss can also be minimized.

本例の可破壊部５は樹脂製で、リング４と一体に成形されたものであるが、リング４と別の素材からなるものとしても良い。また、リング４の上端に、吊下紐３と同様の比較的短い紐を、リング４の一部として設けておき、この紐の先端に可破壊部５を設けても良い。更に、可破壊部５を、本例ではリング４と一体としたが、これと逆に、吊下紐３と一体としても良い。この場合、拡大部３１を逆にリング４の側に設ける必要がある。結局、吊下紐３とリング４とのうちで一方側の端部には可破壊部５が、他方側の端部には拡大部３１が設けられたものであれば良く、本例のものに実施の形態が限定されるものではない。   The breakable portion 5 of this example is made of resin and is formed integrally with the ring 4, but may be made of a material different from that of the ring 4. Alternatively, a relatively short string similar to the hanging string 3 may be provided at the upper end of the ring 4 as a part of the ring 4, and the breakable part 5 may be provided at the tip of the string. Furthermore, although the destructible portion 5 is integrated with the ring 4 in this example, it may be integrated with the suspension string 3 on the contrary. In this case, it is necessary to provide the enlarged portion 31 on the ring 4 side. After all, it is sufficient that the breakable portion 5 is provided at the end portion on one side and the enlarged portion 31 is provided at the end portion on the other side of the hanging string 3 and the ring 4. However, the embodiment is not limited to the above.

また、貫通孔５２ａに関しても、本例のものに限られず、種々の形態での実施が可能である。例えば、上端部５２の中央に円形の孔を設けておき、この孔と側方部５３とを結ぶスリットから構成された鍵穴のような孔であっても良い。また、上記のように、破壊時において、貫通孔５２ａを拡大部３１により押し広げやすくするために、貫通孔５２ａの周囲に更にスリットや切れ目を設けたものとしても良い。   Further, the through hole 52a is not limited to the one in this example, and can be implemented in various forms. For example, a circular hole may be provided in the center of the upper end portion 52, and a hole such as a keyhole formed by a slit connecting the hole and the side portion 53 may be used. Further, as described above, in order to facilitate the expansion of the through hole 52a by the enlarged portion 31 at the time of destruction, a slit or a cut may be further provided around the through hole 52a.

次に、本例では、上記のように拡大部３１が中空部５１に配された状態の可破壊部５を、外部から覆うことのできるキャップ６が設けられている。このキャップ６は、図３に示すように、上端側が閉鎖された中空筒状体とされており、内径が可破壊部５の側方部５３の外面に嵌合可能な寸法とされたものであって、上端部６１の中央には、吊下紐３の挿通部３２が通過可能な貫通孔６１ａが設けられている。   Next, in this example, the cap 6 which can cover the destructible part 5 in the state where the enlarged part 31 is arranged in the hollow part 51 as described above is provided. As shown in FIG. 3, the cap 6 is a hollow cylindrical body whose upper end is closed, and has an inner diameter that can be fitted to the outer surface of the side portion 53 of the breakable portion 5. In the center of the upper end portion 61, a through hole 61a through which the insertion portion 32 of the hanging string 3 can pass is provided.

このように、キャップ６が可破壊部５を覆うことにより、可破壊部５から拡大部３１が外れてしまうことを防止できる。また、上記のように可破壊部５が破壊されて可破壊部５と拡大部３１とが分離した際に、本体部２に内蔵された巻取り機構によって吊下紐３の全体が不意に本体部２に巻き取られた際でも、このキャップ６が引っ掛かることにより、少なくともキャップ６及び拡大部３１が本体部２の外部に露出した状態とできる。よって、その後リング４を取り替える際においても、本体部２に巻き取られた吊下紐３を取り出すために、いちいち本体部２を分解する必要もなく、容易に取り替え作業を行うことができ、復旧が容易である。   As described above, the cap 6 covers the destructible portion 5, and thus it is possible to prevent the enlarged portion 31 from being detached from the destructible portion 5. In addition, when the destructible portion 5 is destroyed as described above and the destructible portion 5 and the enlarged portion 31 are separated, the entire hanging strap 3 is unexpectedly moved by the winding mechanism built in the main body portion 2. Even when wound on the part 2, the cap 6 is hooked so that at least the cap 6 and the enlarged part 31 are exposed to the outside of the main body part 2. Therefore, even when the ring 4 is subsequently replaced, it is not necessary to disassemble the main body 2 every time in order to take out the hanging string 3 wound around the main body 2, and the replacement work can be easily performed and restored. Is easy.

また、この貫通孔６１ａの存在により、拡大部３１が可破壊部５の貫通孔５２ａに対して横方向にずれないようにでき、過負荷時の可破壊部５の破壊が確実に行われるようにできる。   Further, the presence of the through hole 61a can prevent the enlarged portion 31 from shifting laterally with respect to the through hole 52a of the destructible portion 5, so that the destructible portion 5 can be reliably destroyed during overload. Can be.

また、上記に加え、キャップ６の内側面には、図３（Ｂ）に示すように、可破壊部５の貫通孔５２ａに嵌合可能であるキー状の突起６２が設けられている。この突起６２の嵌合は、貫通孔５２ａの、側方部５３へと開口された側のスリット形状の一端側に対してなされる。この突起６２は、キャップ６自体の可破壊部５に対する位置決めをなすことができるものであり、加えて、上記と同様に、拡大部３１が可破壊部５の貫通孔５２ａに対して横方向にずれないようにする作用も有する。   In addition to the above, as shown in FIG. 3B, a key-like protrusion 62 that can be fitted into the through hole 52 a of the destructible portion 5 is provided on the inner surface of the cap 6. The projection 62 is fitted to one end side of the slit-shaped side of the through hole 52 a that is open to the side portion 53. The protrusion 62 can position the cap 6 itself with respect to the breakable portion 5, and in addition, the enlarged portion 31 extends laterally with respect to the through hole 52 a of the breakable portion 5 in the same manner as described above. It also has an effect of preventing deviation.

なお、本願発明において、キャップ６は必須のものではない。例えば、本体部２の吊下紐３が通過する部分の孔の径を拡大部３１の径よりも小さく形成することで、吊下紐３の本体部２への巻き込みを防止するものであっても良い。また、可破壊部５と拡大部３１との間の外れ止めは、スリット状の貫通孔５２ａのうち、側方部５３に対して開口された部分をかしめて閉じることによって行っても良い。   In the present invention, the cap 6 is not essential. For example, the diameter of the hole of the portion through which the hanging cord 3 of the main body portion 2 passes is formed smaller than the diameter of the enlarged portion 31, thereby preventing the hanging cord 3 from being caught in the main body portion 2. Also good. Further, the detachment prevention between the breakable portion 5 and the enlarged portion 31 may be performed by caulking and closing a portion opened to the side portion 53 of the slit-like through hole 52a.
