    • A collapsible frame structure (12), movable between an open arrangement and a folded arrangement, includes a plurality of legs (18), a plurality of cross members (22) arranged in pairs, a plurality of slider joints (30,40) and pivot joints (24), and at least one latch mechanism (50). Each pair of cross members (22) is located between respective adjacent legs (18) to form sides of the collapsible frame structure (12) that define an interior of the collapsible frame structure(12) . Each slider joint(30,40) slidingly engages a respective one of the legs (18) and pivotably attaches to two adjacent cross members (22) Each pivot joint (24) is at a respective one of the legs (18) to pivotably attach two adjacent cross members (22). The latch mechanism(50), which is mounted to another frame component of the collapsible frame structure(12), remains so mounted in both the open arrangement and the folded arrangement. Nonadjacent legs (18) and nonadjacent sides of the collapsible frame structure (12) remain unconnected across an interior of the collapsible frame structure (12).
    • 可拆卸框架结构(12),其可在打开布置和折叠布置之间移动,包括多个支腿(18),成对布置的多个横向构件(22),多个滑块接头(30,40)和 枢轴接头(24)和至少一个闩锁机构(50)。 每对横向构件(22)位于相应的相邻腿部(18)之间,以形成限定可折叠框架结构(12)内部的可折叠框架结构(12)的侧面。 每个滑块接头(30,40)滑动地接合相应的一个腿部(18)并且可枢转地附接到两个相邻的横向构件(22)。每个枢转接头(24)在相应的一个腿部(18)处以可枢转地附接 两个相邻的横向构件(22)。 安装在可折叠框架结构(12)的另一框架部件上的闩锁机构(50)保持安装在打开布置和折叠布置中。 可折叠框架结构(12)的不相邻的腿部(18)和不相邻的侧面在可折叠框架结构(12)的内部保持未连接。
