摘要： A locking mechanism for a support leg hingedly attached to a support surface. The locking mechanism includes a base, attached to the support surface, with a plurality of angularly spaced, radial teeth, and a coupler, attached to the support leg, having a plurality of angularly spaced, radial teeth configured to mate with the teeth of the base. A selectively releasable engagement mechanism is configured to engage and disengage the teeth of the base with the teeth of the coupler, to allow selective rotation of the support leg between an extended position and a folded position, and to lock the leg in the extended or folded position.

摘要： A joint between a leg and an elevated platform includes a tapered receptacle with straight widening walls coupled to one of either the leg or the platform. A mating insert is coupled to the other of the leg or the platform and is selectively insertable into the tapered receptacle. The mating insert has straight narrowing walls that are engageable with the widening walls of the tapered receptacle. The weight of the platform pushes the insert into the receptacle such that the narrowing walls of the insert engage the widening walls of the tapered receptacle.

摘要： A folding chair has a rigid support frame with a curved spline profile, and a seat and rear legs which fold into a closed position and substantially collapse within a volume defined by the support frame to maximize stacking density, and to increase stability with the curved spline profiles nesting within one another. The support frame has first and second rigid side support members, each with an upper back support portion and extending forwardly to form front leg portions. The back support portion and the front leg portions are integrally and rigidly connected to advantageously form a curved spline profile. A seat is pivotally coupled to the support frame, or to and between the first and second support members. A majority of the seat advantageously collapses to a folded position within a volume defined between the first and second rigid side support members. Rear legs are pivotally coupled to the support frame, or to the respective first and second support members. A majority of the rear legs advantageously collapses to a folded position within the volume defined by the support frame between the first and second rigid support members.

摘要： A tabletop formed from slats for use in rigid, light-weight tables, such as portable banquet tables. The tabletop includes a center section formed from a plurality of open-channel, rectangular tubular slats that are laterally coupled together. Each slat has a top wall that aligns with top walls to form the upper working surface of the tabletop. Each slat also has downwardly-projecting sidewalls and a bottom wall with a longitudinal slot running the length of the slat to form the rectangular, downwardly-orientated channel. The adjacent contacting sidewalls of adjacent slats coupled together to form substantially vertical support beams. The tabletop further includes a pair of elongate end caps disposed on opposite ends and spanning the plurality of slats of the center section, with each end cap having a plurality of finger pairs extending into the plurality of slats with a center slot the receives a support beam therein.

摘要： A folding chair has a support frame with a back support portion, front leg portions, and rear legs. A seat is pivotally coupled to the support frame. A flexible back support is coupled to the support frame, and has a lumbar support member extending down from the back support to reach a lumbar region of a user's back. The lumbar support member extends from the back support into a space between the back support and seat. The seat pivots in a downward direction away from the back support and lumbar support ID member, so that the seat folds without interfering with the lumbar support member. The back support also has a perimeter flange disposed across the rigid back support perimeter, and free to move with respect to the rigid support frame in response to a load applied to the flexible back support. The perimeter flange extends across a gap created between the flexible back support and the support frame, such that when a load is applied to the back support and the back support flexes, causing the gap to open, the perimeter flange conceals the gap as the flexible back support goes from a loaded position to an unloaded position, thereby preventing pinching of articles of clothing or skin of a user.
摘要翻译：折叠椅具有支撑框架，其具有后支撑部分，前腿部分和后腿部。座椅枢转地联接到支撑框架。柔性背部支撑件联接到支撑框架，并且具有从后支撑件向下延伸以到达使用者背部的腰部区域的腰部支撑构件。腰部支撑构件从背部支撑件延伸到后部支撑件和座椅之间的空间中。座椅沿向后方向枢转，远离后支撑件和腰部支撑件ID构件，使得座椅折叠而不会妨碍腰部支撑构件。背部支撑件还具有设置在刚性后部支撑周边上的周边凸缘，并且响应于施加到柔性背部支撑件的负载而相对于刚性支撑框架自由移动。周边凸缘延伸穿过在柔性背部支撑件和支撑框架之间产生的间隙，使得当负载施加到后支撑件并且后支撑件弯曲时，导致间隙打开时，周边凸缘将该间隙隐藏为柔性背部支撑从装载位置移动到卸载位置，从而防止使用者的衣服或皮肤的夹持。
