PROBLEM TO BE SOLVED: To provide a furniture door lock device of a simple structure that prevents a furniture door from opening unexpectedly due to tampering by a child or shaking due to an earthquake and other reasons, and may be fitted afterwards on an existing sliding door readily.SOLUTION: A furniture door lock device includes: an outer tube part 29 fitted by piercing through a sliding door 15; a protruded rod 31 that is movable in a direction along an axial line 47 inside the outer tube part 29 and around the axial line, and may be inserted into and withdrawn from an engaging hole 49 freely, the engaging hole being pierced through the other sliding door 25 in a door frame part or a door meeting part 27; an operation part 33 formed integrally with the protruding rod 31 and exposed on a surface 57 of the sliding door 15; an energizing member 35 that energizes the protruding rod 31 toward a direction to be withdrawn from the engaging hole 49; a guide pin 37 extended in a radial direction on either an inner periphery of the outer tube part 29 or on an outer periphery of the operation part 33; and a cam groove 39 disposed on the other of the inner periphery of the outer tube part 29 or the outer periphery of the operation part 33 and engaged with the guide pin 37, for regulating a position of the protruded rod 31 between a position engaged with the engaging hole 49 and a withdrawn position.SELECTED DRAWING: Figure 6
【課題】簡素な構造で製造でき、子供の悪戯、地震による揺れ等による不用意な開放が防止でき、既存引戸への後付も容易に行うことを可能とする。【解決手段】引戸１５を貫通して取り付けられる外筒部２９と、外筒部２９の内方で軸線４７に沿う方向及び軸線回りで可動自在となって戸枠部、または、召し合わせ部２７における他の引戸２５に穿設される係合穴４９に対して挿脱自在な突出杆３１と、突出杆３１と一体に形成され引戸１５の表面５７に露出される操作部３３と、突出杆３１を係合穴４９から抜脱する方向に付勢する付勢部材３５と、外筒部２９の内周または操作部３３の外周の何れか一方に半径方向に延在して設けられるガイドピン３７と、外筒部２９の内周または操作部３３の外周の何れか他方に設けられて、ガイドピン３７に係合して突出杆３１を係合穴４９に係合させる位置と離脱させる位置とに位置規制するカム溝３９と、を設けた。【選択図】 図６
