The present invention relates to a height-adjustable table (1) height-adjusting arrangement (100) for adjusting the height of the table (1), wherein the height-adjusting arrangement (100) comprises at least one leg, each leg having an inner tubular member (112) and an outer tubular member (113) arranged for telescopic movement relative to each other, and a linear actuator (114) coupled to said tubular members (112, 113) and which is configured to provide the telescopic movement between the tubular members (112, 113), and an electric motor connected to the linear actuator (114) and configured to operate the linear actuator for providing telescopic movement between the tubular members. The height-adjusting arrangement (100) further comprises an eye detection unit arranged to detect the position of a user's eyes. The height-adjusting arrangement (100) is configured for control of the height of the height-adjustable table (1) based on the detected position of a user's eyes.

A lock device (30) is disclosed, which comprises: a holder (31) which is provided with a through hole (312) running through the holder (31) and a slide (311) intersecting with the through hole (312); a guide bar (32), which is provided with an outer threaded area on at least a portion of a surface and passes through the through hole (312), where the outer threaded area is located at where the through hole (312) intersects with the slide (311); a lock component (35) received in the slide (311), where the end of the lock component (35) facing towards the guide bar (32) is provided with a lock threaded area which can engage with the outer threaded area of the guide bar (32); and a drive assembly which drives the lock assembly to move towards or away from the guide bar (32) in the slide (311). In the embodiments of present disclosure, the guide bar is locked when threads on the lock threaded area engage with outer threads on the outer threaded area. The lock devices according present disclosure are simple, easy to maintain, low cost, not ease to failure, with high reliability and able to bear very large load. In addition, they will not generate noise and need not to be operated with electricity, and the operation is more convenient.

The present disclosure is directed to console furniture and related features. A support structure is provided for supporting a work surface, the support structure comprising a frame defining an interior space, a frame brace receivable into the interior space of the frame, a support for supporting the work surface, and at least one fastening mechanism for extending between the frame brace and the support to clamp the frame therebetween, thereby securing the support about the frame. A console with a height adjustable work surface is also provided.

An adjustable desk platform can include an upper platform defining a first substantially planar work surface and a lower platform defining a second substantially planar work surface. At least one set of pivot arms can connect the lower platform and the upper platform. The set of pivot arms can comprise a primary pivot arm and a secondary pivot arm, wherein the set of pivot arms is adapted to move the upper platform substantially in parallel with the lower platform between a fully raised position and a fully lowered position. A locking mechanism can be associated with the set of pivot arms. The locking mechanism can include: a plurality of perforations located in the primary pivot arm or the secondary pivot arm, a locking set fixed with respect to the upper platform or the lower platform, the locking set including at least one anchor adapted to selectively engage at least one of the plurality of perforations, and a handle connected to the anchor by a linkage. The handle can be adapted to selectively move the anchor into engagement with at least one of the plurality of perforations. Other embodiments and features are also discussed.

An apparatus and method provide various desk structures as workstations to receive a user, standing or sitting, walking or stationary, exercising or sedentary. A double duty desk system may include multiple, dedicated "sitting desks" at seated height and fixed to a shared "standing desk," the height of whose desktop stands accessible to a user exercising on an exercise bike, treadmill, stepper, or the like. A user in an exercise (e.g., standing) position may view materials set on the standing desk and on the attached sitting desks and returns. Heights of desks may be permanently fixed, adjustable, powered, mechanized, manual, or a combination. A user may selectively exercise or sit, in order to read, browse online, attend webinars, edit, monitor, handwrite, type, lecture, listen, answer phones, make calls, develop software, or the like from a standing or sitting position, at will.

A fuse and fuse module that facilitate ampacity rejection based on electrical contact location is disclosed. A configuration of electrical contacts in the fuse and a corresponding configuration of fuse slots in the fuse holder permit fuses within an acceptable range of ampacities to be installed in the fuse holder while at the same time preventing fuses within an unacceptable range of ampacities from being installed in the fuse holder.
