家具物品的自稳定支撑组件
Self-stabilizing support assembly for an item furniture
US-7677524-B2用于家具的自稳定支撑组件，防止倾倒。
专利摘要
本发明涉及一种用于家具物品（如桌子、凳子或椅子）的自稳定支撑组件(14)。该组件包括支撑结构(16)，其上端用于连接到家具物品的上部。支撑结构在其下端(22)具有第一对支脚(50)。细长的导销(38)从支撑结构的下端突出。可移动支撑构件(30)具有第二对支脚(32)，并设有限定导引通道的外壳(36)，导引销在导引通道中可纵向滑动地接收。外壳构造成使得导引通道的横截面积可调节，以允许相对于导引销确定导引通道的尺寸，使得响应于可移动支撑构件绕横向于外壳的枢转轴枢转，导引销与限定导引通道的外壳壁自动摩擦接合，从而将可移动支撑构件摩擦地锚定以防止相对于导引销滑动位移。
Original abstractThe invention relates to a self-stabilizing support assembly ( 14 ) for an item of furniture, such as a table, stool or chair. The assembly includes a support structure ( 16 ) for connection at an upper end thereof to an upper portion of an item of furniture. The support structure has a first pair of feet ( 50 ) at a lower end ( 22 ) thereof. An elongated guides pin ( 38 ) projects from a lower end of the support structure. A displaceable support member ( 30 ), which has a second pair of feet ( 32 ), is provided with a housing ( 36 ) defining a guide passage, in which guide passage the guide pin is longitudinally slidably received. The housing is constructed such that a cross-sectional area of the guide passage is adjustable, to permit dimensioning of the guide passage relative to the guide pin such that automatic frictional engagement of the guide pin with walls of the housing defining the guide passage occurs in response to pivoting of the displaceable support member about a pivot axis transverse to the housing, to anchor the displaceable support member frictionally against sliding displacement relative to the guide pin.
