Definitions

  • Coupling and coupling system for swivably coupling an arm to a post in particular for coupling a monitor arm to a support
  • the invention generally relates to a coupling for swivably coupling an arm to a post, in particular for coupling a monitor arm to a support, for example for swivably coupling a monitor arm to a post of a desk monitor stand or a wall monitor mount.
  • Monitor supports are well known, and are used to position monitors, typically flat panel displays, at a desired viewing position on a desk or a wall.
  • a monitor support comprises a post that extends along a longitudinal axis, a monitor arm for supporting a monitor radially outward relative to the longitudinal axis of the post, and a coupling with which the monitor arm in use is swivably coupled to the post.
  • the post may e.g. be supported on a desk or wall, directly via e.g. a clamp or plate, or indirectly via e.g a further arm.
  • Monitor stands may in practice be fairly complex in their configuration, and may include several posts.
  • a desk monitor stand may e.g. include a first post that is embodied as a main column that is supported by the desk, and that swivably carries a monitor arm via a coupling.
  • Such first post may include a mounting track so that, in addition to a swivel angle of the monitor arm, the position of the arm on the longitudinal axis of the post may be set to position the monitor at a desired height above the desk.
  • a desk monitor stand may also include a post that is embodied as an
  • intermediate post e.g. in case of an articulated monitor arm that includes two arms that are swivably connected to a common post via a coupling, e.g. to increase the reach of the stand.
  • a monitor stand may further be complicated because the monitor stand may have multiple monitor arms, e.g. a single post that is embodied as a main column may carry two or more separate arms to allow different monitors carried on the stand to each service another desk, or to allow more monitors to be placed in a compound viewing plane of a single desk.
  • a post need not always extend upright, but may e.g. also extend transversely, e.g. in case of a monitor support that is embodied as a wall mount or a (cross)bar.
  • a monitor support upon manufacture or installation a monitor support needs to be configured so that its arm services a specific area, e.g. depending on the position of the stand on the desk. This way, it can be prevented that the monitor can touch a back wall, or a left or right side wall during adjustment. Also, it may be prevented that a monitor reaches outside a service area into another service area, e.g. a service area of an adjoining desk. This is typically done by using complex mechanisms and specific parts to control swivehng of the arms about the posts.
  • an existing monitor support needs to be reconfigured so that its arm can service a new service area, e.g. when the stand is moved to a different position on a desk, to a different desk, or when a stand is

  • the limited relative rotational movement may be provided in one of the interfaces, or in both interfaces. As an alternative or in addition, it may also be provided within the coupling itself.

  • the coupling can in a specific orientation not complete a full revolution, but facilitates through reorientation that the work area can be selected from rotational sub zones that together correspond to a full revolution.
  • a single revolution as meant herein is a about a full turn. It preferably corresponds to 360 degrees, but may in practice be slightly more or slightly less, e.g. more than 330 or 345 degrees, and less than 375 or 390 degrees.
  • the post interface and the arm interface may comprise a rotation limiter that in use hmits rotational movement of the interface relative to its engaged element about a swivel axis that extends along a longitudinal axis of the post.

  • the slot may in swiveling direction be oversized to receive tab with play to form a non-fixating rotation limiter with limited stroke.
  • the coupling may include at least two protrusions, each having a slot to increase stabihty. Indeed, more slots are provided than
  • protrusions so that for each protrusion one out of more slots may be selected to engage. This facilitates (re)configuration of the coupling without the need to substitute parts.
  • the coupling may be arranged to engage the post and the arm in two or more discrete rotational orientations about the swivel axis relative to the arm and/or the post, each orientation allowing limited relative rotation about the swivel axis along a different trajectory,
