Abstract: Collapsible articles of furniture comprise at least one leg assembly including a first leg and a second leg, each with an upper leg segment and a lower leg segment coupled together by a link. The two links are pivotally connected to each other for movement between an open position wherein the first and second legs cross each other to form a generally X-shaped configuration and a closed position wherein the upper and lower leg segments are aligned, the upper leg section of the first leg receivable within the lower leg section of the second leg and the upper leg section of the second leg is receivable within the lower leg section of the first leg.

Abstract translation: 可折叠家具制品包括至少一个腿组件，其包括第一腿部和第二腿部，每个腿部组件具有通过连杆联接在一起的大腿部段和小腿部段。 两个连杆彼此枢转地连接，以在第一和第二腿彼此交叉的打开位置之间运动，以形成大致X形的构型和闭合位置，其中上腿和下腿段对齐，上腿部分 在第二腿的小腿部分内可接收的第一腿部和第二腿部的大腿部分可接收在第一腿部的小腿部分内。

Abstract: Collapsible articles of furniture are provided which have at least one leg assembly which includes a first leg and a second leg. The first leg has a first upper leg segment and a first lower leg segment coupled to the upper leg segment by a first link and the second leg has a movable second upper leg segment and a fixed second lower leg segment coupled to the upper leg segment by a second link. The two links are pivotally connected to each other for movement between an open position wherein the first and second legs cross each other to form a generally X-shaped configuration and a closed position wherein the upper and lower leg segments are aligned with each other and the upper leg section of the first leg is received within the lower leg section of the second leg and is aligned with and telescopically received within the lower leg section of the first leg. The pair of control links pivotally supported in a space between the link plates move in response to movement of the plates prevent telescopic connection between the upper and lower leg segments and prevent the upper leg segments from being telescopically received within the lower leg segments until a predetermined condition of alignment between the upper and lower leg segments has been attained.
