To prevent falling and slip of furniture in earthquake time.SOLUTION: Furniture 3 comprises a grounding device 6 for vertically movably supporting an operation member 11 having a seismic member 13 on a lower end thereof, by a support member 10. A swing member 14 of an operation mechanism 7 is pivotally supported to the support member 10, for vertically moving the operation member 11 energized upward by a first spring 25. A shaft member 40 is coupled to the swing member 14 on a same shaft core, the other end 40A of the shaft member 40 is pivotally supported to the attachment member 42. An operation pedal 41 is coupled to the other end 40A of the shaft member 40 through an engagement member 44. The operation pedal 41 switches a position of the seismic member 13 between an upper non-grounding position and a lower grounding position according to the operation. A holding mechanism 8 is provided on the engagement member 44 and the attachment member 42, for holding the operation pedal 41 between the non-grounding position and the grounding position.SELECTED DRAWING: Figure 5

    【課題】地震時、家具の転倒や滑りを防止する。【解決手段】家具3には、下端に免震部材13が設けられた動作部材11を支持部材10により上下動可能に支持する接地装置6が設けられる。支持部材10には、操作機構7の揺動部材14が軸支され、第1のばね25により上方に付勢された動作部材11を上下動させるようになっている。揺動部材14には、同一軸芯上に軸部材40が連結され、この軸部材40の他端40Aは、取付部材42に軸支される。軸部材40の他端40Aには、係合部材44を介して操作ペダル41が連結される。操作ペダル41は操作に応じて、免震部材13を上方の非接地位置と下方の接地位置とに切り替えるようになっている。係合部材44と取付部材42とには、保持機構8が設けられ、操作ペダル41を非接地位置と接地位置とで保持するようにしている。【選択図】図5
