用作可折叠桌子，便于收纳和携带。
专利摘要
公开了一种具有两级折叠机构的折叠桌。该折叠桌包括分为第一平面部分和第二平面部分的桌面。一对侧轨连接到每个平面部分。可折叠的腿和支撑支架连接到每个平面部分。铰链组件设置在第一平面部分和第二平面部分之间。铰链组件包括铰链销、第一铰链连接器和可旋转地设置在铰链销上的第二铰链连接器。第一铰链连接器具有凸轮部分。锁定销穿过第二铰链连接器中的槽设置，使得当锁定销定位在最靠近铰链轴线的位置时，凸轮部分抵靠锁定销，从而锁定桌面。当锁定销定位在离铰链轴线最远的位置时，第一铰链连接器能够围绕铰链轴线自由旋转。锁定致动机构可用于操作锁定销，并可提供锚定或加强机构以将锁定销保持在锁定位置。
Original abstractA folding table is disclosed having a two-stage folding mechanism. The folding table includes a table top divided into a first planar portion and a second planar portion. A pair of side rails is connected to each planar portion. A foldable leg and support brace is connected to each planar portion. A hinge assembly is provided disposed between the first planar portion and the second planar portion. The hinge assembly includes a hinge pin, a first hinge connector and a second hinge connector rotatably disposed on the hinge pin. The first hinge connector has a cam portion. A locking pin is disposed through a slot in the second hinge connector so that when the locking pin is positioned nearest the hinge axis, the cam portion abuts the locking pin, thus locking the table top. When the locking pin is positioned farthest from the hinge axis, the first hinge connector is able to freely rotate about the hinge axis. A lock actuating mechanism may be used to operate the locking pin and may provide an anchoring or reinforcing mechanism to maintain the locking pin in a locked position.
