Description

本発明は、主に、室内の天井面に取り付けて、物干具や観葉植物や絵画等を吊り下げて使用する吊掛装置に関するものである。 The present invention mainly relates to a hanging device that is attached to a ceiling surface of a room and hangs a clothes drying tool, a houseplant, a painting, or the like.

従来より、前述のような吊掛装置として特開平６−１２１７２５号公報に記載された発明のように、本発明と同様に頭体の下端部に上接続部を設けると共に、シャフトの上端部に下接続部を設けて成り、緩衝ばねは、その上下端部を上接続部と下接続部にそれぞれ接続させて成る吊掛装置は提案されている。
特開平６−１２１７２５号公報 Conventionally, as in the invention described in Japanese Patent Application Laid-Open No. 6-121725 as a suspension device as described above, an upper connection portion is provided at the lower end portion of the head body as in the present invention, and the upper end portion of the shaft is provided. There has been proposed a suspension device that is configured by providing a lower connection portion, and the buffer spring has upper and lower ends connected to an upper connection portion and a lower connection portion, respectively.
JP-A-6-121725

この種の吊掛装置においては、引掛部に一定以上の重いものを吊り下げた場合、吊掛具は、緩衝ばねが伸びて外れて、取り付けられている天井が壊れるのを防止するようになっている。その際に、上記従来例においては、その詳細な説明中に上接続部と下接続部の接続強度に関する記載がないことから、あるいは、その図面から、それぞれの接続強度を相違させた構造とはなっていないと推定できるものであり、上接続部から外れるか、下接続部から外れるかわからず、上接続部から外れた場合には、吊掛具は、緩衝ばねと共に落下するものであり、伸びきった緩衝ばねの鋭利な端部が人に当たって怪我をする危険性があるという問題がある。 In this type of hanging device, when a heavy object of a certain level or more is suspended from the hanging portion, the hanging device prevents the buffered spring from extending and breaking the ceiling to which it is attached. ing. At that time, in the above-described conventional example, there is no description about the connection strength of the upper connection portion and the lower connection portion in the detailed description, or from the drawing, the structure in which each connection strength is different. It can be presumed that it is not, and it is not known whether it comes off from the upper connection part or the lower connection part, and when it comes off from the upper connection part, the hanging tool is to fall together with the buffer spring, There is a problem that the sharp end of the extended buffer spring may hit the person and cause injury.

本発明は、吊掛具の緩衝ばねが伸びて外れた場合でも、人を傷つける危険を極力回避できるようにすることを課題とするものである。 An object of the present invention is to make it possible to avoid as much as possible the risk of damaging a person even when a buffer spring of a hanging tool extends and comes off.

上記課題を解決するために、天井面等に固定される支持具と、支持具に取り付けられ、引掛部を設けてある吊掛具を有し、吊掛具は、シャフトの上端部に緩衝ばねを介して頭体を設けてある吊掛装置において、頭体の下端部に上接続部を設けると共に、シャフトの上端部に下接続部を設けて成り、緩衝ばねは、その上下端部を頭体の上接続部とシャフトの下接続部にそれぞれ接続させて成り、下接続部は上接続部よりも接続強度が弱い構造としたものである。 In order to solve the above-described problems, a support device fixed to a ceiling surface or the like, and a suspension device attached to the support device and provided with a hook portion, the suspension device is provided with a buffer spring at an upper end portion of the shaft. In the hanging device provided with the head through the upper body, the upper connection portion is provided at the lower end portion of the head body, and the lower connection portion is provided at the upper end portion of the shaft. The upper connection portion of the body and the lower connection portion of the shaft are connected to each other, and the lower connection portion has a structure in which connection strength is weaker than that of the upper connection portion.

以上のように本発明によれば、シャフトの上端部の緩衝ばねは、その上下端部を頭体の上接続部とシャフトの下接続部にそれぞれ接続させて成り、下接続部は、上接続部よりも接続強度を弱くして成るので、引掛部に一定以上の重いものを吊り下げて、万が一吊掛具の緩衝ばねが伸びて外れた場合でも、緩衝ばねの下接続部の接続が外れ、緩衝ばねが頭体に取り付けられたまま残って落下することがなく、伸びきった緩衝ばねの鋭利な端部が人を傷つけることがなく、万が一の時の安全性を向上させることができるという効果がある。 As described above, according to the present invention, the buffer spring at the upper end portion of the shaft is formed by connecting the upper and lower end portions to the upper connection portion of the head body and the lower connection portion of the shaft, respectively. Because the connection strength is weaker than that of the part, even if a heavy object of a certain level or more is suspended from the hook part, even if the buffer spring of the hanging part extends and comes off, the connection of the lower connection part of the buffer spring is disconnected. The shock absorbing spring remains attached to the head and does not fall, and the sharp end of the shock absorbing spring does not hurt people, improving safety in the event of an emergency. effective.

本発明の吊掛装置は、天井面等に固定される支持具１に、略棒状の吊掛具２を着脱可能に取り付けて成るものである。 The hanging device of the present invention is formed by detachably attaching a substantially rod-shaped hanging tool 2 to a support 1 fixed to a ceiling surface or the like.

吊掛具２は、シャフト７の下端にリング状の引掛部６を設け、上端に緩衝ばね４を介して頭体３を取り付けられ、この頭体３の上部を支持具１に挿入して回動することによって、吊掛具２が支持具１に対して着脱することができるようになっている。着脱する機構については、例えば前記特開平６−１２１７２５号公報に記載された機構でもよいし、他の機構でもよく、さらに、吊掛具２を支持具１に取り付けられたまで、着脱することができなくてもいいもので、ここでは省略する。 The hanging device 2 is provided with a ring-shaped hooking portion 6 at the lower end of a shaft 7, the head body 3 is attached to the upper end via a buffer spring 4, and the upper portion of the head body 3 is inserted into the support device 1 to rotate. The hanging tool 2 can be attached to and detached from the support tool 1 by moving. The mechanism for attaching and detaching may be, for example, the mechanism described in the above-mentioned Japanese Patent Application Laid-Open No. 6-121725, or may be another mechanism. Further, the attachment and detachment may be performed until the hanging device 2 is attached to the support device 1. I don't need to do this, so I'll omit it here.

頭体３には、下半部に上接続部８を設ける共に、接続具５には、上半部に下接続部９を設けて成り、緩衝ばね４の上下端部をそれぞれ上接続部８と下接続部９に接続してある。緩衝ばね４は、引掛部６に下方向に急激に大きな荷重がかかった時や吊掛具２が揺動する方向に力がかかった時に、伸長してその衝撃を緩和する機能を有している。 The head body 3 is provided with an upper connecting portion 8 in the lower half, and the connector 5 is provided with a lower connecting portion 9 in the upper half, and the upper and lower ends of the buffer spring 4 are respectively connected to the upper connecting portion 8. Are connected to the lower connection part 9. The buffer spring 4 has a function of extending and relieving the impact when a large load is suddenly applied to the hook portion 6 in the downward direction or when a force is applied in the swinging direction of the hanging tool 2. Yes.

頭体３の上接続部８には、周囲の一部に螺旋溝１０を刻設し、接続具５の下接続部９には、周囲の一部に螺旋溝１１を刻設すると共に中央に割溝１２を設けてあり、緩衝ばね４にそれぞれの螺旋溝１０、螺旋溝１１をねじ込んで取り付ける。 A spiral groove 10 is engraved in a part of the periphery of the upper connection portion 8 of the head 3, and a spiral groove 11 is engraved in a part of the periphery of the lower connection portion 9 of the connector 5 and at the center. A split groove 12 is provided, and the spiral groove 10 and the spiral groove 11 are screwed and attached to the buffer spring 4.

緩衝ばね４は、かかる荷重が一定範囲内であれば、伸長した後その荷重を取り除けば元に戻るが、その一定範囲を越える荷重がかかると、伸長したままとなり、さらに大きな荷重をかけると、取り付けられた天井面が壊れないようにするために、外れるようになっている。 If the load is within a certain range, the buffer spring 4 will return to its original state after removing the load, but if the load exceeding the certain range is applied, the buffer spring 4 will remain stretched and if a larger load is applied, In order to prevent the installed ceiling surface from being broken, it comes off.

下接続部９は、その螺旋溝１１は上接続部８の螺旋溝１０よりも浅く短く、なおかつ中央に割溝１２を設けて内側方向に撓みやすくしており、緩衝ばね４は下接続部９からの方が外れやすい構造となっている。なお、外れやすくする構造としては、上記のように、浅く、短く、割溝を設けるという３つの要素を全て備えていなくても、そのうちの２つの要素でも、１つの要素でもよく、要するに、下接続部が上接続部よりも接続強度が弱い構造となっていればよい。 The lower connecting portion 9 has a spiral groove 11 which is shallower and shorter than the spiral groove 10 of the upper connecting portion 8 and is provided with a split groove 12 at the center to bend easily inward, and the buffer spring 4 has a lower connecting portion 9. It has a structure that is easier to remove. As described above, the structure for facilitating disengagement may not be provided with all of the three elements that are shallow, short, and provided with a dividing groove, but may be two elements or one element. The connection part should just be a structure whose connection strength is weaker than an upper connection part.

吊掛具２の引掛部６に一定範囲を越える大きな荷重がかかると、緩衝ばね４は、頭体３の上接続部８に接続したままで、接続具５の下接続部９から外れることになり、支持具１に緩衝ばね４を残して吊掛具２は落下する。なお、下接続部９は、シャフト７と別体の接続具５を固定してそこに設けてあるが、シャフト７に直接設けるようにすることもできる。 When a large load exceeding a certain range is applied to the hooking part 6 of the hanging tool 2, the buffer spring 4 is disconnected from the lower connection part 9 of the connection tool 5 while being connected to the upper connection part 8 of the head 3. As a result, the suspension hook 2 falls while leaving the buffer spring 4 on the support 1. In addition, although the lower connection part 9 fixes the shaft 7 and the connection tool 5 separate, it is provided there, but it can also be made to provide in the shaft 7 directly.

従って、吊掛具２が万が一落下しても、緩衝ばね４は落下せず、伸びきった緩衝ばね４の鋭利な端部が人を傷つけることがない。 Therefore, even if the hanging tool 2 falls, the buffer spring 4 does not fall, and the sharp end portion of the buffer spring 4 that has been extended does not injure people.
