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 invention aims to provide a coupling for swivably coupling an arm to a post, in particular for swivably coupling a monitor arm to a post of a monitor support, with which these problems are alleviated.
- the invention aims to provide a coupling for swivably coupling an arm to a post that allows configuration and re-configuration in a simple operation, without requiring substitution of parts and/or tools, and that is inexpensive to manufacture.
- the invention provides a coupling for swivably coupling an arm to a post, the coupling in use cooperating with the post as an engaged element via a post interface, and with the arm as an engaged element via an arm interface, wherein the coupling including its interfaces provides limited relative rotational movement between the arm and the post about a swivel axis extending along a longitudinal axis of the post, wherein the limited rotational movement is provided in a rotational zone that corresponds to a single revolution about the longitudinal axis.
- 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 limited relative rotational movement provided by the coupling and its interfaces may be provided in rotational sub zones that in one orientation of the coupling are less than a single revolution, and that through reorientation of the coupling about its swivel axis relative to arm and/or post together correspond to a single revolution.
- 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.
- At least one of the post interface and the arm interface may include a non-fixating rotation limiter that in use engages its engaged element with a limited rotational stroke to allow limited relative rotation about the swivel axis between the arm and the post.
- the coupling may comprise a substantially cylindrical body portion that extends along the swivel axis.
- a radial inner mantle surface of the body portion may be part of the post interface, and a radial outer mantle surface of the body portion may be part of the arm interface.
- Such coupling bushing may be manufactured from plastics material e.g. through injection molding.
- the coupling bushing may be a single part, but may also be composed of several parts.
- both the post interface and arm interface may include a non-fixating rotation limiter, a coupling may be provided with which swiveling of a single, complete rotation of 360° can be obtained relatively easily, through aggregation of the limited free strokes at both interfaces.
- Both non-fixating rotation limiters may then have the same swivel axis.
- protrusion may extend radially relative to the swivel axis, e.g. radial inwardly when arranged at the post interface, and radial outwardly when arranged at the arm interface.
- the protrusion may extend parallel to the swivel axis.
- the protrusion may be embodied as a tab that is arranged to engage a corresponding slot in the engaged element at the interface that also extends parallel along the swivel axis.
- the slot may in swiveling direction about the longitudinal axis be of matching size to receive the tab without play so as to form a fixating rotation limiter.
- 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,
- the coupling may be engageable on the post in different positions about its axis, and/or it may be reversible upside down.
- rotation limiter By embodying the rotation limiter to include a groove that in use cooperates with the engaged element at the interface via a traveler, a reliable non-fixating rotation limiter may be provided at low cost.
- the traveler may be embodied as an intermediate element between the engaged elements at the interface.
- the traveler may also be part of the engaged element at the interface, e.g. a finger.
- the groove is a ball race, and the traveler is a ball.
- a non-fixating rotation limiter may be provided that is inexpensive, has good running properties, and that can easily be made adjustable.
- the groove may extend about the swivel axis less than 360°, and can e.g. form a ring segment.
- the coupling may include two or more such grooves, each of different angular orientation with respect to the swivel axis.
- the groove may also extend about the swivel axis 360° or more, and can then e.g. form a helix.
- the invention also relates to a coupling system comprising a post and an arm, and a coupling as discussed above.
- the system may be sold as a kit. In assembled condition the post interface may engage the post, and the arm interface may engage the arm.
- the arm may be provided with a recess for receiving the arm interface of the coupling.
- the arm may e.g. comprise a further coupling for receiving a monitor.
- the arm may comprise an adjustable stop, e.g. a track with one or more stop screw(s) that may be used to limit or prevent travel of the ball in the groove.
- an adjustable stop e.g. a track with one or more stop screw(s) that may be used to limit or prevent travel of the ball in the groove.
- the post may be provided on a further arm. This way, a reliable articulated arm may be formed cost effectively, that can also be

- the invention also relates to a monitor support comprising at least one post that extends along a longitudinal axis, a monitor arm for
- the post of the monitor support may be embodied as a first post and/or as an intermediate post.
- the coupling may reliably be held in an aperture in the monitor arm, e.g. a substantially ring-shaped aperture that in use at least partially surrounds the circumference of the post.
- an aperture in the monitor arm e.g. a substantially ring-shaped aperture that in use at least partially surrounds the circumference of the post.

- Fig. 8 shows a schematic exploded view of a seventh embodiment of the invention for swivably coupling an arm to a post in which the post includes four slots.
- a first embodiment of the invention including a coupling 11 for swivably coupling an arm 9 to a post 6.
- the coupling 11 cooperates with the post 6 as an engaged element via a post interface 13, and with the arm 9 as an engaged element via an arm interface 12.
- the coupling 11 is held in a substantially ring-shaped aperture 10 that surrounds the circumference of the post 6.
- the coupling 11 comprises a substantially cylindrical body portion that extends along the swivel axis A and that forms a single part bushing that is arranged between the post 6 and the monitor arm 9.
- the post interface 13 includes a radial outer mantle surface of the post 6, and a radial inner mantle surface of the body portion of the coupling 11.
- the arm interface 12 includes a radial outer mantle surface of the body portion of the coupling 11, and a radial inner mantle surface of the arm 9. Both the post interface 13 and the arm interface 12 comprise a rotation limiter that in use limits rotational movement of the interface relative to its engaged element about a swivel axis A that extends along a longitudinal axis of the post 6.
- the rotation limiter on the post interface 13 here is a fixating rotation limiter which includes a protrusion 14.
- the protrusion is embodied as a tab 15 that extends radially inwardly, from the inner mantle surface of the coupling 11, towards the swivel axis A.
- the tab 15 is arranged to engage a corresponding slot 7 of matching size in the post 6, that also extends parallel along the swivel axis A.
- the rotation limiter on the arm interface here is a non-fixating rotation limiter that in use engages with the arm 9 with a limited rotational stroke to allow limited relative rotation about the swivel axis A between the arm 9 and the post 6.
- the non-fixating rotation limiter comprises a helical groove 18, on the outer mantle surface of the coupling 11, that in use cooperates with the arm 9 via a traveler 19.
- the groove 18 is embodied as a ball race that extends about the swivel axis A in a helical path of 360°, and that forms a ring segment.
- the traveler 19 is embodied as a ball 20, which is held in a drop-in slot 21 at the aperture 10 in the arm. Via the non-fixating rotation limiter formed by the ball 20 and groove arrangement 18, a limited rotational movement is provided in a rotational zone that corresponds to a single revolution about the longitudinal axis A.
- FIG. 2a, 2b, 2c and 2d an application of the first embodiment of the invention is shown that forms a monitor support 4 that is embodied as a monitor desk mount. It includes a post 6 that is provided with a clamp 5.
- the desk clamp 5 is mounted substantially in the middle of a rear edge of a desk 1.
- On the post 6 that is carried on the clamp 5 a configuration is mounted that basically corresponds to the first embodiment discussed above, but that differs in the use of two protrusions 14, and two slots 7.
- the post 6 on the clamp 5 forms a first post 6 of the monitor support 4, about which a lower arm 9 may be swivably coupled via a first coupling 11.
- the end of the lower arm carries a second post 8, about which an upper arm 9 is swivably coupled via a second coupling 11 to form an articulate monitor arm.
- the second coupling 11 is identical to the first coupling 11 (except for its height), and the intermediate post 8 is configured similar to the first post 6 to match the coupling 11.
- the free end of the upper arm 9 carries a further post 8, and a swivel bracket 3 which carries a monitor 2.
- Fig. 2a shows a first configuration in which the groove 18 and ball 20 of both the first and second coupling 11 cooperate to limit rotation when the upper and lower arms 9 overlap, i.e. cooperate to act as an end-stop against further rotation. This can be used to protect a back wall when a monitor 2 in front of the user is pushed away, see arrows D. Clockwise movement of the lower arm 9 about the first post 6 is free for 360 degrees, and so is counterclockwise movement of the upper arm 9 relative to the intermediate post 8.
- Fig. 2b shows a second configuration that corresponds to Fig. 2a, but that differs in that the first coupling 11 has been reoriented by lifting it off the first post 6, rotating it together with the lower arm 9 180 degrees about the swivel axis A relative to the post 6, and replacing it on the post 6.
- the upper arm 9 has been readjusted by rotating it 360 degrees about the intermediate post 8, so that it again overlaps the lower arm 9, but now both arms 9 are located on the left of the first post 6 instead of on the right as they did in Fig. 2a.
- the rotation hmiters now cooperate to limit rotation equal to Fig. 2a. i.e. when the arm 9 is in front of a user and a monitor 2 is pushed away.
- Fig. 2c shows a third configuration that corresponds to Fig. 2a, but that differs in that the monitor stand 4 has been relocated with its desk clamp 5 to a left corner of a desk 1.
- the desk may be provided with a corner grommet mount.
- the configuration further differs in that the upper arm 9 carried by the second post 8 has been reconfigured by lifting the second coupling 11 up from the second post 8 along the swivel axis, rotationally reorienting the coupling 11 by 180° about the swivel axis A relative to the post 8, and pushing the coupling 11 back down on the post 8 along the swivel axis.
- the upper arm 9 and the lower arm 9 no longer overlap, but extend away.
- the rotation limiters now cooperate to limit rotation to protect the back wall. Clockwise movement of the lower arm 9 about the first post 6 is free for 360 degrees, and so is clockwise movement about the intermediate post 8.
- Fig. 2d shows a fourth configuration that corresponds to Fig. 2c, but differs in that the configuration is relocated with its desk clamp 5 to a right corner of a desk 1.
- the configuration further differs in that the lower arm 9 carried by the first post 6 provided with a clamp 5 has been
- a second embodiment of the invention is shown in which a non-fixating rotation limiter is formed at the post interface 13 by a slot 7 in the post 8 that is oversized in swiveling direction, and that receives the tab 15 with play.
- a rotation limiter with a compound stroke of 360 degrees is obtained. Rotation is limited when the arms 9 overlap.
- Fig. 3b shows a second configuration that corresponds to Fig. 3a, but differs in that the upper arm 9 carried by the post 8 has been
- the non-fixating rotation limiter on the arm interface 12 includes a radially outwardly projecting tab 15 on the outer mantle of the coupling body that cooperates with an oversized slot 7 in the arm.
- the non-fixating rotation limiter on the post interface 13 includes a ball race 17 in the post 8, of which the ball 20 is held in a drop -in slot 21 in the inner mantle of the bushing 11. Similar to Fig. 3a, rotation is hmited when the arms 9 overlap.
- Fig. 4b shows a second configuration that corresponds to Fig. 4a, but that differs in that the second (upper) arm 9 carried by the post 8 has been 180° reconfigured. Similar to Fig. 3b, the rotation limiters now cooperate to limit rotation when the arms 9 extend away.
- the fourth embodiment is a variation on the first embodiment, and includes a helical groove 18 with adjustable stops 23 as a non-fixating rotation limiter.
- the arm 9 comprises a track with two set screws 23 that may be used to limit travel of the ball 20 in the groove 18.
- the set screws 23 may be provided with manually operable heads, so that they can be adjusted in a toolless operation.
- the rotation hmiter can be reversibly adjusted between a non-fixating and a fixating position.
- a single stop screw 23 may be used.
- the end of the track 18 can then form the second stop.
- a fifth embodiment of the invention is shown in which the configuration is inverted again.
- a slot 7 is provided in the arm that matches in size with a tab 15 that extends from the coupling body at its outer mantle so as to provide a fixed rotation limiter at the arm interface 12.
- a rotation limiter with a compound stroke of 360 degrees is provided at the post interface 13.
- a first non-fixating rotation limiter is provided by a circumferential groove 17 at the top of post 8 that cooperates with a travelling ball 20 held in the inner mantle surface of the coupling body.
- the circumferential groove 17 forms a circle segment of less than 360 degrees.
- a second non-fixating rotation limiter is formed by a
- the ball 20 is held in place by a top flange (not shown).
- a slot 7 is provided in the arm 9 that matches in size with a tab 15 that extends from the coupling body at its outer mantle so as to provide a fixed rotation limiter at the arm interface 12.
- a non-fixating rotation hmiter with a stroke of 270 degrees is provided, as indicated by arrow D.
- the post 8 carries a finger 26 that cooperates with a 270 degree slot in a top surface of the body of the coupling 11.
- the finger 26 may be detached using screw 27, and may be reoriented to be held in in any of the four arms of a mounting cross 28 at the top surface of the post 8 in which the finger 26 is held.
- the limited relative rotational movement is provided in four rotational sub zones of 270 degrees each.
- the rotational sub zones are each in one orientation of the coupling less than a single revolution, and through reorientation of the coupling 11 about its swivel axis A relative to the post 8 and the arm 9 together correspond to a single revolution.
- the work area can thus be selected from rotational sub zones that together correspond to a full revolution.
- a seventh embodiment of the invention is shown with a post 6 that includes four slots 7, and a coupling 11 that swivably couples an arm 9 to the post 6.
- the coupling 11 includes a fixating rotation hmiter at the post interface 13 that comprises two opposing radially inwardly extending tabs 15 at the inner mantle surface of the coupling body. The tabs 15 fit into the slots 7 in the post 6, occupying two opposing slots 7 at one time.
- the coupling 11 further includes a non-fixating rotation hmiter at the arm interface 12 that comprises a quarter circle circumferential groove 17 in the outer mantle surface of the coupling body that cooperates with the arm 9 via a travelling ball 20 held in a drop -in slot 21 in the arm 9.
- Fig. 8 it is shown by depicting four identical couplings 11 and arms 9, that through reorientation of the coupling 11 relative to the post 6 by rotating it 90 degrees about its swivel axis A, the work area of the arm 9 can be selected from four 90 degree rotational sub zones that together
- each arm 9 having its own quadrant of service.
- the coupling disclosed herein may summarily be expressed as a coupling for swivably coupling an arm to a post, the coupling comprising a post interface that in use cooperates with the post as engaged element, and an arm interface that in use cooperates with the arm as engaged element, wherein both the post interface and the arm interface comprise a rotation hmiter 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.
- At least one of the post interface and the arm interface may include a non-fixating rotation limiter that in use engages its engaged element with a limited rotational stroke to allow limited relative rotation about the swivel axis between the arm and the post.
- the coupling may be assembled of various pieces, and may e.g. be built up from two parts that cooperate via wedge surfaces such as described in PCT NL2016/050798.
- the angular values discussed may be chosen differently, and the shape and configuration of the arms and the posts may vary. Examples of shapes and configurations of monitor arm stands are also described in
