PROBLEM TO BE SOLVED: To provide a topped furniture item with a small number of components that exerts a big braking force with a small operational force so as to be prevented from moving in use, while easily releasing restriction of movement when moved.SOLUTION: A table device has a driving mechanism 60 for allowing a rear stopper member 52 to appear and disappear comprises: a swing member 55 that rotates around a first support shaft 56 so as to allow the rear stopper member 52 to come in and out of contact with a floor surface; and a linkage member 61 that is rotatably supported around a second support shaft 61s and has a lower end provided with a sliding shaft 61t capable of sliding along a guide groove 57 formed at the swing member 55. When the rear stopper member 52 is in contact with the floor surface, the linkage member 61 swings in a posture inclined beyond a vertical direction, the sliding shaft 61t bumps against a rear end 57b of the guide groove 57, and thereby sliding is restricted.SELECTED DRAWING: Figure 4
【課題】使用状態においては天板付什器が移動しないように小さな操作力で大きな制動力を発揮しつつ、移動させる際には移動の拘束を容易に解除するとともに、部品点数を抑える。【解決手段】テーブル装置において、後部ストッパ部材52を出没させる駆動機構60は、第一支持軸56回りに回動することによって後部ストッパ部材52を床面に対して接離させるスイング部材55と、第二支持軸61s回りに回動自在に支持されるとともに、下端部にスイング部材55に形成されたガイド溝57に沿ってスライド可能なスライド軸61tを有した連係部材61と、を備える。また、後部ストッパ部材52が床面に接地した状態で、連係部材61が揺動され鉛直方向を超えて傾斜した姿勢であるとともに、スライド軸61tはガイド溝57の後方の端部57bに突き当たってスライドが拘束される。【選択図】図4
