[0028] Certain exemplary embodiments of the display support system relate to a movable arm support configured to support a display that is heavier than the weight that can typically be supported by a conventional movable support arm. Furthermore, certain embodiments provide one or more force adjustment mechanisms that allow a user to change the balancing force of the arm as needed.

[0029] Figure 1 shows an exemplary embodiment of a support system 100 for a display, which includes a mounting section 102. The mounting section 102 is configured to secure the support system 100 to a support surface (not shown). The mounting section 102 may have a clamp member 104 that can be connected to various surfaces or supports, such as a desk, table, or wall, as will be understood by those skilled in the art. A first arm 106 extends from the mounting section 102. In a particular embodiment, the first arm 106 is rotatably connected to the mounting section. An intermediate joint 108 is rotatably connected to the distal portion of the first arm 106. A second arm 110 is rotatably connected to the intermediate joint 108. A head joint 112 is rotatably connected to the distal portion of the second arm 110. A tilt mechanism 114 is movably connected to the head joint 112. A display mount (not shown), such as a VESA display mount, may be connected to the tilt mechanism 114 to receive the display, or the display may be directly connected to the tilt mechanism. The first arm 106, intermediate joint 108, second arm 110, head joint 112, and tilt mechanism 114 may each include a single-piece or multi-piece housing component, for example, the first and second components being connected to each other. Other housing components may be connected as needed. One or more cable handling or management devices 116 may be provided on one or more of the arms to organize and hold the cables extending to the display. The first arm 106, intermediate joint 108, second arm 110, head joint 112, and tilt mechanism 114 constitute an exemplary embodiment of the support structure, but other forms of the support structure may also be used.

[0030] As best illustrated in Figure 1, the first arm 106 can rotate around a first vertical axis A1 with respect to the support or surface. The intermediate joint 108 can rotate around a second axis A2 with respect to the first arm 106. The second arm 110 can rotate around a third axis A3 with respect to the intermediate joint 108. The head joint 112 can rotate around a fourth axis A4 with respect to the second arm 110. The tilt mechanism 114 can rotate around a fifth axis A5 and a sixth axis A6 with respect to the head joint 112. In the illustrated embodiment, the first axis A1 and the second axis A2 are vertical axes. The third axis A3 and the fourth axis A4 are horizontal axes. The fifth axis A5 is a vertical axis, and the sixth axis A6 is a horizontal axis. In the exemplary embodiment, the sixth axis A6 is a virtual axis positioned at a distance from the tilt mechanism 114 so as to pass through either the display mount or a portion of the display connected to the display mount.

[0031] Figures 2 and 3 show an exemplary set of components of a second arm 110, which preferably includes a housing 120. The housing 120 holds a first spring casing 122 and a second spring casing 124. A first spring 126 is positioned within the first spring casing 122, and a second spring 128 is positioned within the second spring casing 124. A first spring bracket 130 is connected to the first spring casing 122, and a second spring bracket 132 is connected to the second spring casing 124. A pair of spring links 134 are connected to the first spring bracket 130 and an intermediate coupling 108. In a particular configuration, the spring link 134 is preferably connected to the intermediate joint 108 around a third axis A3 under a rotatable connector of the second arm 120 and the intermediate joint 108. A first spring adjustment mechanism 136 is positioned within the housing 120, and this first spring adjustment mechanism extends into the first spring casing 122. A lockout mechanism 138 is positioned within the housing 120, and this lockout mechanism engages with the second spring casing 124.

[0032] In a particular configuration, the direct link 140 has a first portion rotatably connected to an intermediate joint 108 and a second portion rotatably connected to a head joint 112. The direct link 140 preferably penetrates the housing 120 and passes through a second spring casing 124 and a second spring 128. During the movement of the second arm 110 from the raised position to the lowered position, the direct link 140 causes the head joint 112 to rotate about the horizontal axis A4, so that the mounted display maintains its position relative to the support surface during the rotation of the second arm 110.

[0033] In the illustrated embodiment, the first spring 126 and the second spring 128 are coil springs that exert a biasing force in response to spring compression. This force is applied to the first and second spring brackets 130, 132 and transmitted to the intermediate joint 108 via the spring link 134. This force is used to counteract the downward force on the second arm 110 applied by the load of the display connected to the second arm 110.

[0034] In the illustrated embodiment, the first and second springs 126, 128 are shown as upper and lower springs relative to the housing 120. Other embodiments may have the first and second springs 126, 128 in various positions and configurations to initially provide a balancing force to the arm 110. Other embodiments may also utilize various biasing members as needed.

[0035] The first spring adjustment mechanism 136 preferably includes a shaft 142 connected to an adjustable plate 144. The first spring 126 abuts the adjustable plate 144 at its distal end relative to the intermediate joint 108. The adjustable plate 144 is preferably screwed to the shaft 142 and keyed to the housing 120, so that rotation of the shaft 142 causes translational motion of the adjustable plate 144 within the housing 120. The shaft 142 is preferably rotatable by the user to move the adjustable plate 144 as desired or as needed, depending on the weight of the display. The shaft 142 preferably has a rear portion accessible to the user through an opening provided in the housing 120. The shaft 142 preferably has a user interface (e.g., a thumbwheel, a hexagonal socket, etc.) that allows user engagement and rotation. A window 146 is preferably provided in the housing 120 so that the user can visually check the position of the adjustment plate 144. To allow the user to more easily determine the adjustment amount and position of plate 144, one or more indicators may be provided in window 146 or the adjacent housing 120.

[0036] The lockout mechanism 138 is configured to disengage the second spring 128, thereby reducing or eliminating the balancing force provided by the second spring 128. In certain embodiments, the lockout mechanism 138 can disengage the second spring 128, resulting in the absence of a biasing force transmitted by the second spring 128, which in turn offsets the mounted load over at least a portion of the travel distance of the second arm 110.

[0037] The illustrated embodiment shows a first spring adjustment mechanism 136 associated with the upper spring and a lockout mechanism 138 associated with the lower spring, but these components can be reversed or moved to different positions depending on the spring configurations.

[0038] Figures 4 and 5 show exemplary embodiments of the first and second spring casings 122, 124, the first and second spring brackets 130, 132, and the spring lockout mechanism 138. In a particular embodiment, the second spring casing 124 and the second spring bracket 132 engage with the first spring casing 122 and the first spring bracket 130 to provide the spring link 134 with the sum of the biasing forces of both the first spring 126 and the second spring 128. The second spring casing 124 can move relative to the first spring casing 122 by the lockout mechanism 138, and as a result, the second spring casing 124 and the second spring bracket 132 disengage from the first spring casing 122 and the first spring bracket 130 over at least a portion of the rotational movement of the second arm 110 relative to the intermediate joint 108.

[0039] In a particular configuration, the first spring casing 122 has a substantially open first end 150 through which the first spring 126 is inserted. The first spring 126 can be seated at a substantially closed second end 152 of the spring casing. The upper portion of the first spring casing 122 has a curved shape, however different shapes and dimensions can be used depending on the outer or inner surface structure of the housing 120.

[0040] The lower portion of the first spring casing 122 has one or more grooves 154 in the outer surface of the first spring casing 122 and extending along at least a portion of the first spring casing. The grooves 154 are preferably provided on each side of the first spring casing 122. As best shown in Figure 6, the grooves 154 receive a first rail 156 formed on the housing 120. Although only a single side is shown, a second side may have the same configuration. The slidable engagement of the rail 156 and the grooves 154 allows the first spring casing 122 to translate relative to the housing 120. This translation helps to minimize or eliminate any bending or torsional forces generated by the first spring 126 during the movement of the second arm 110 or the housing components, and helps to ensure smooth movement of the second arm 110.

[0041] The lower portion of the first spring casing 122 further has a base with a projection 158 below the groove 154 and extending toward the rear of the first spring casing 122. The projection 158 preferably has a front wall 160. An opening is formed in the projection 158 to receive a fastener 162 and connect the first spring bracket 130 to the first spring casing 122. In a particular embodiment, the fastener 162 fixes the horizontal position of the first spring casing 122 and the first spring bracket 130 relative to each other. The fastener 162 is shown as a horizontally extending pin, but other fasteners or different mechanical connectors can be used.

[0042] In a particular configuration, the second spring casing 124 has a substantially open first end 166 through which the second spring 128 is inserted. The second spring 128 can be seated on the substantially closed second end 168 of the second spring casing 124. The lower portion of the second spring casing 124 has a curved shape, however different shapes and dimensions can be used depending on the outer or inner surface structure of the housing 120.

[0043] The upper portion of the second spring casing 124 has one or more grooves 170 in the outer surface of the second spring casing 124 and extending along at least a portion of the second spring casing. These grooves are preferably provided on each side of the second spring casing. As best shown in Figure 6, the grooves 170 receive a second rail 172 formed on the housing 120. The slidable engagement of the rail 172 and the grooves 170 allows the second spring casing 124 to translate relative to the housing 120. This translation helps to minimize or eliminate any bending or torsional forces generated by the second spring 128 during the movement of the second arm 110 or components of the housing 120, and helps to ensure smooth movement of the second arm 110.

[0044] The upper portion of the second spring casing 124 further has a rear wall 174. The rear wall 174 of the second spring casing 124 aligns with the front wall 160 of the first spring casing 122 during assembly. A rear projection 176 extends outward from the rear wall 174. The rear projection 176 engages with the second spring bracket 132 during assembly. Preferably, an opening is formed in the second spring casing 124 to receive a fastener 178 and connect the second spring bracket 132 to the second spring casing 124. In a particular embodiment, the fastener 178 fixes the horizontal positions of the second spring casing 124 and the second spring bracket 130 relative to each other. The fastener 178 is shown as a horizontally extending pin, but other fasteners or different mechanical connectors can be used.

[0045] In a particular configuration, the second spring casing 124 has one or more flanges 180 that extend downward at an oblique angle and away from the end portion of the second spring casing 124. Preferably, a pair of flanges 180 that straddle each side of the direct link 140 are used. Preferably, these flanges 180 extend outside the housing 120 and are visible to the user to confirm the position of the second spring casing 124 set by the lockout mechanism 138. Preferably, the angle of the flanges 180 is set to provide clearance that allows the movement of the second arm 110 relative to the first arm 106 and the intermediate joint 108.

[0046] In a particular configuration, the first spring bracket 130 has a wall 182 and a pair of arms 184 extending from the wall 182. The rear end of the first spring bracket 130 is preferably engaged with the wall 182. The wall 182 is preferably having an opening through which the adjustment mechanism 136 can pass. The first and second arms 184 are preferably positioned to extend outside the first spring casing 122. Openings are provided in each of the first and second arms 184 to receive fasteners 162 and connect the first spring bracket 130 to the first spring casing 122.

[0047] In a particular configuration, the second spring bracket 132 has a base 186 and a pair of arms 188 extending from the base 186. A slot is preferably formed between the base 186 and the arms 188 to receive the projection 176 of the second spring casing 124. Openings are provided in each of the first and second arms 188 to receive fasteners 178 and connect the second spring bracket 132 to the second spring casing 124.

[0048] In a particular embodiment, the lockout mechanism 138 includes a rotatable member 190 connected to a fastener 178 of the second spring casing 124. The rotatable member 190 is preferably screw-connected to the fastener 178 that connects the second spring bracket 132 to the second spring casing 124. The housing 120 is preferably configured to restrict the movement of the rotatable member 190 in at least one axial direction. In the illustrated embodiment, the rotatable member 190 has a head that is captured by one or more projections formed in the housing 120 to restrict the backward movement of the rotatable member 190, as best shown in Figure 3. The lockout mechanism 138 associated with the second spring casing 124 is preferably able to move in a forward direction during the movement of the second arm 110 from an elevated position to a lowered position.

[0049] The rotatable member 190 may have a user interface (e.g., a thumbwheel, a hexagonal socket, etc.) that allows the user to engage and rotate it. The user can rotate the rotatable member 190, which results in the translation of the fastener 178 in the axial direction of the rotatable member 190. The movement of the fastener 178 causes the second spring bracket 132 and the second spring casing 124 to move closer to or away from the first spring bracket 130 and the first spring casing 122 in response. The housing 120 may be provided with one or more slots or grooves 194 to provide restricted movement of the second spring bracket 132 and the second spring casing 124 relative to the housing 120.

[0050] As best illustrated in Figure 7, in a particular embodiment, when the lockout mechanism 138 is disengaged, the second spring bracket 132 engages with the first spring bracket 130, and the second spring casing 124 engages with the first spring casing 122, although only one of the engagements can be used. In this embodiment, the forces of the first spring 126 and the second spring 128 are exerted on the spring link 134 to balance the load of the display.

[0051] In some applications, the weight of the display may not require the force of both springs 126,128. In such cases, the user may engage the lockout mechanism 138, thereby driving the fastener 178 forward. This moves the second spring bracket 132 and the second spring casing 124 forward, disengaging them from the first spring bracket 130 and the first spring casing 122 for at least a portion of the motion of the second arm, as shown in Figure 8.

[0052] In a particular configuration, when the arm is in its lowest position, the first spring casing 122 can be driven forward by the spring link 134, so that the first spring bracket 130 and the first spring casing 122 engage with the second spring bracket 132 and the second spring casing 124, even when the lockout mechanism 138 is fully engaged. In a particular configuration, the lockout mechanism 138 can be used to position the second spring casing 124, so that the second spring 128 engages at a specific point of movement (e.g., an intermediate position) on the second arm 110 when the second arm 110 is rotating relative to the first arm 106.

[0053] In the exemplary embodiment described above, the second spring casing 124 is moved to disengage the second spring 128, but other conceivable embodiments may utilize different mechanisms to disengage the second spring 128. For example, a separate plate or other member may be positioned to disengage the spring by moving, for example, the rear end of the spring into the housing. Such a plate may be positioned within the casing, or it may be used in a housing separate from the casing.
