Technical Field

Embodiments described herein relate generally to stands and supports for electronic devices. More particularly, the embodiments relate to a support arm mount for a computer display.

Background

Computer device designers typically desire to control the positioning of a computer monitor or similar display at any height and orientation that is best suited to the needs of the user. This allows the display to accommodate users of different heights, sizes and postures and desktop surfaces of different heights, sizes. The user also generally prefers to adjust the positioning of the monitor with less effort.

While various existing display stands provide tilt, swivel, and vertical height adjustment for the monitor, these features often come at the expense of ease of use and naturalness. For example, it may be difficult to mount the monitor to the stand, especially when the rear side of the monitor is not easily accessible, or when the monitor is mounted to the stand when the stand is in an upright position. These problems can make using a display stand difficult, laborious, and time consuming, and prevent the stand from being of high quality, thereby satisfying the user experience. Accordingly, there is a continuing need for improvements in gantries and supports for electronic devices.

Disclosure of Invention

One aspect of the present disclosure is directed to a display assembly comprising an electronic display having a display panel and a housing, wherein the display panel is positioned in the housing, wherein the housing has a mounting recess, and wherein the mounting recess has a sidewall surface having at least one laterally extending recess. The display assembly may also include a support arm configured to support the electronic display relative to the ground surface, wherein the support arm has a mounting portion with a set of laterally extending latches configured to be positioned in at least one laterally extending recess to retain the mounting portion in the mounting recess of the electronic display, and at least one latch of the set of laterally extending latches is laterally retractable relative to the mounting portion.

In some embodiments, the display assembly can further include a display stand attached to the support arm at an end of the support arm opposite the mounting portion. The at least one laterally extending recess may comprise a set of laterally extending recesses in the sidewall surface that receive the set of laterally extending latches. The electronic display may further include a first magnetic structure and the mounting portion may include a second magnetic structure, wherein the first magnetic structure and the second magnetic structure attract each other when the mounting portion is positioned in the mounting recess.

In some embodiments, the mounting portion may be circular and the set of laterally extending latches may be spaced circumferentially around the mounting portion. At least one latch of the set of laterally extending latches may be biased into an extended position relative to the mounting portion. The mounting portion may include a switch configured to retract at least one latch of the set of laterally extending latches. The electronic display may be rotatable relative to the mounting portion when the mounting portion is held to the electronic display. In some embodiments, the electronic display may be capable of rotating from a landscape orientation and a portrait orientation in only one direction of rotation.

The housing may include a first magnetic structure and the mounting portion may include a second magnetic structure, wherein the first and second magnetic structures attract each other when the mounting portion is positioned in the mounting recess. The first and second magnetic structures may be aligned along an axis, and the first and second magnetic structures may each include at least one magnetic portion having poles oriented radially with respect to the axis.

Another aspect of the present disclosure is directed to a display support arm comprising a first end, a second end, a first magnetic structure, and a second magnetic structure; the first end is configured to attach the arm to a support surface; the second end is configured to attach the arm to a display, wherein the second end includes a surface facing the display; the first magnetic structure is positioned in the second end and has a first magnetic axis perpendicular to the display-facing surface; the second magnetic structure is positioned in the second end and has a second magnetic axis parallel to the display-facing surface.

The support arm may further include a third magnetic structure positioned in the second end and having a third magnetic axis parallel to the display-facing surface, wherein the third magnetic structure is positioned opposite the first magnetic structure relative to the second magnetic structure. The second and third magnetic structures may each include an inner end along respective second and third magnetic axes, wherein the polarity of the second and third magnetic structures at the inner ends match.

The second magnetic axis may intersect the first magnetic axis. The second magnetic axis may extend through a width of the first magnetic structure. The surface facing the display may comprise grooves or ridges configured to interface with corresponding ridges or grooves of the display. The grooves or ridges may have an overall width across the surface facing the display, wherein the overall width of the grooves or ridges is greater than the overall width of the first and second magnetic structures.

Yet another aspect of the present disclosure is directed to a monitor assembly that includes a stand, a support arm pivotally attached to the stand, and a monitor pivotally attached to a monitor mounting portion, wherein the support arm is rotatable relative to the stand between a raised position and a lowered position, and wherein the support arm has a monitor mounting portion. The monitor may be rotatable relative to the support arm between a landscape orientation and a portrait orientation, and the monitor mounting portion allows the monitor to be rotated from the landscape orientation to the portrait orientation when the support arm is in the raised position, prevents the monitor from being rotated from the landscape orientation to the portrait orientation when the support arm is in the lowered position, and prevents the support arm from being rotated relative to the stand when the monitor is in the portrait orientation.

In some embodiments, the support arm and the pin-and-slot feature of the monitor prevent rotation of the monitor relative to the support arm. Rotation of the monitor to a portrait orientation may prevent rotation of the support arm relative to the gantry. The monitor may be capable of being disconnected from the monitor mounting portion.

Detailed Description

Reference will now be made in detail to the exemplary embodiments illustrated in the accompanying drawings. It should be understood that the following description is not intended to limit the embodiments to any preferred embodiment. On the contrary, it is intended to cover alternatives, modifications, and equivalents as may be included within the spirit and scope of the embodiments as defined by the appended claims.

The following disclosure relates to display stand assemblies and related methods that can make the use of stands intuitive, safe, and robust. Conventional display stands include a top hook and a spring latch or screw mount. Once assembled, the display can be rotated between landscape and portrait orientations with respect to the gantry. In either case, the user needs to actively move the latch or apply the screw to attach the display to the stand, and these activities can only be performed from the back side of the screen. A user attempting to mount the display to the stand from the front of the display cannot do so. If the display stand or display is not movable to a position where the back of the display is accessible, the user cannot mount the display.

Aspects of the present disclosure relate to implementations of a display stand attachment method in which a combination of magnetic features and latches work together to allow "blind" mounting of a display to a mounting portion (i.e., a mounting portion or "puck") of a stand. In other words, a user can hold the display from a viewing side of the display and can mount the display to the stand without the mounting portion of the stand being visible and without having to awkwardly reach behind the display to secure the mounting portion to the display. In some implementations, the user can quickly and easily "snap" the display to the mounting portion with a single horizontal movement of the display relative to the support arm on the stand, and then release the display without disconnecting the display from the mounting portion.

Magnets in the display and in the mounting portion of the support arm can guide and center the display relative to the mounting portion (or vice versa) to assist a user in inserting the mounting portion into a recess in the display. Thus, the magnet may reduce or eliminate the need for a user to see the position of the recess on the display relative to the mounting portion of the support arm due to the magnetic attraction that guides the mounting portion to the receiving recess of the display.

Once the two devices have been coupled, a set of retractable latches of the mounting portion can keep the display secured to the support arm. As such, when a relatively large moment or other unintended input force is applied to the display (e.g., a user pushes against a corner of the display or accidentally pulls on an edge of the display), the magnetic attachment between the display and the support arm may be less easily disengaged. The latch may be connected to the release mechanism to remove the display from the mounting portion or rotate the display relative to the mounting portion. At least one of the latches may include a feature to prevent the display from inadvertently sliding off the mounting portion when the release mechanism is operated.

Another aspect of the present disclosure relates to an apparatus and method for controlling rotation and movement of a support arm and a display when the support arm and the display are mated to each other. The support arm and the display may include an interactive feature that limits rotation of the display relative to the mounting portion unless the display is in a raised position. For example, when the display is in a lowered position relative to the stand, the display may be mechanically prevented from rotating from a landscape orientation to a portrait orientation, thereby preventing the display from rotating into contact with a desktop or other support surface below the stand. In the raised position, rotation of the display may be mechanically unlocked or otherwise enabled, allowing the display to move to the portrait orientation when its height relative to the support surface is sufficient to provide clearance between the support surface and the rotating display. Additionally, the display may be mechanically prevented from translating vertically relative to the gantry when the display is in the portrait orientation so as to limit contact between the portrait-oriented display and the support surface or gantry.

These and other embodiments are discussed below with reference to the figures. Those skilled in the art will readily appreciate that the detailed description given herein with respect to these figures is for explanatory purposes only and should not be construed as limiting. Features from one embodiment may be implemented in other embodiments.

Fig. 1-15 illustrate various aspects of a display assembly 100. Fig. 1 and 2 show front and right side views of an electronic display 102 coupled to a support arm 104 that is coupled to a gantry 106. Fig. 3-4 illustrate the display 102 coupled to the support arm 104 in a raised position relative to the configuration shown in fig. 1-2. In fig. 1-4, the display 102 is shown in a landscape orientation, and in fig. 5-6, the display is in a raised position and a portrait orientation. As used herein, a "landscape orientation" or "landscape position" of a display is an orientation of a display device in which the viewable display area of the device is elongated in a horizontal direction relative to a vertical direction. A "portrait orientation" or "portrait position" of a display device is an orientation in which the viewable display area of the device is elongated in a vertical direction relative to a horizontal direction. Generally, the transverse orientation is rotated 90 degrees about the central axis Y relative to the longitudinal orientation. See fig. 8.

The display assembly 100 may be a stand-alone assembly in which the support arm 104 and the stand 106 are configured to support the weight of a single display 102. In some embodiments, the display assembly 100 may omit the stand 106, and the support arm 104 may be coupled to another support or ground surface, such as, for example, a vertical wall, a horizontal rail extending laterally across the width of the display 102 and behind the display 102, or another similar solid ground structure. In addition, a gantry and support arm having configurations different from those described below may be employed.

The display 102 may include an electronic display, such as a monitor or similar visual output device, for displaying information in pictorial form. The display 102 may include a display device, such as a thin film transistor liquid crystal display (TFT-LCD) with a Light Emitting Diode (LED) or Cold Cathode Fluorescent Lamp (CCFL) backlight or an Organic Light Emitting Diode (OLED) display, circuitry, a housing, such as the housing 1420 in fig. 14, or an enclosure, and a power supply. The display 102 may be configured to connect to a computer using connectors and ports such as a Video Graphics Array (VGA) connector, a Digital Visual Interface (DVI) connector, a displayport (r) connector, a thunder rbolt (r) connector, a radio communication interface, or other related or similar electrical interface.

The display 102 may include a forward facing surface 108 configured to face and display information to a user for viewing thereof. The viewable display area of the display 102 may be viewed through or at the forward facing surface 108. Thus, the forward facing surface 108 may be referred to as a viewing surface. The forward surface 108 may be substantially planar and flat, or the forward surface may be curved (e.g., cylindrical concave or convex). The display 102 may include a rear facing surface 110 configured to face away from a user. The support arm 104 may be positioned between the rearward facing surface 110 and the gantry 106. The support arm 104 may be releasably coupled to the display 102 at the rear facing surface 110 or in a rear portion of the display 102. The mounting portion 111 of the support arm 104 may couple the display 102 to the support arm 104. See also fig. 7-12.

The support arm 104 may also be coupled to a gantry 106. The stand 106 may include a base 112 configured to extend below the display 102, and may include a vertical support 114 configured to extend upward from the base 112 and behind the rearward facing surface 110 of the display 102. The vertical support 114 may have a top end at which the support arm 104 is attached at a gantry attachment point 116. Accordingly, the gantry 106 can be referred to as having a generally L-shaped profile, with the display 102 positioned above the L-shaped base portion 112, as shown in fig. 2, 4, and 6. In some embodiments, the gantry 106 can include horizontal rails, rails and shuttles, or similar structures that extend behind the rear surface 110 and to which the support arm 104 is attached.

The support arm 104 may hold the display 102 in place relative to the gantry 106 and may hold the display 102 in a user-selected vertical position relative to the gantry 106. The support arm 104 can hold the display in a number of different positions, including a lowered position (as shown in fig. 1-2) and a raised position (as shown in fig. 3-6), wherein the position of the display 102 remains stationary (i.e., does not drift or sag downward due to the weight of the display 102 pulling down and rotating the support arm 104). The user may provide an input force oriented in a vertical direction to raise the display 102 relative to the stand 106, such as force F in FIG. 2₁As shown, or the user may provide a vertically oriented input force F₂To lower the display 102 relative to the stand 106 as shown in fig. 4. When the display 102 movesIt may travel through an arcuate path having a radius defined by the length of the support arm 104. By virtue of the parallel motion linkage in the support arm 104, the display 102 can remain upright (e.g., parallel to the vertical support 114, perpendicular to the base portion 112, or otherwise maintained in a single angular orientation relative to the gantry 106) while traveling through an arcuate path.

The user may also provide an input moment M that rotates the display 102 from a landscape orientation (see FIG. 3) to a portrait orientation ₁Or the opposite input moment M that rotates the display 102 from portrait orientation (see FIG. 5) to landscape orientation₂. Moment M₁Is shown as a counterclockwise moment, and moment M₂Shown as a clockwise moment, the display 102 may be designed to use the moment M₁And M₂In either direction, provided that the moment M is₁、M₂The opposite may be true to each other. Additionally, in some embodiments, each moment M may be applied₁、M₂To rotate the display 102 between landscape and portrait orientations. For example, a user may apply a moment M₁To rotate the display 102 from the landscape orientation of fig. 3 to the portrait orientation of fig. 5, and a moment may be applied in the same direction to continue rotating the display 102 from the portrait orientation back to the landscape orientation (e.g., the flipped/inverted landscape orientation or the orientation of fig. 3).

Additional details regarding the display 102, support arm 104, and gantry 106 are provided in fig. 7-20. The support arm 104 is rotatable relative to the gantry 106 and relative to the display 102 about axes 118 and 120, as indicated by the arrows in fig. 8. In some embodiments, the support arm 104 is independently rotatable with respect to the gantry 106 and independently rotatable with respect to the display 102. The support arm 104 may also rotate in a manner that keeps the mounting portion 111 parallel to the gantry 106. Thus, with the display 102 mounted to the support arm 104, movement of the support arm 104 can change the vertical position of the display 102, as shown in fig. 1-4.

The mounting portion 111 of the support arm 104 may include a set of laterally extending latches 122, 124, 126 that extend laterally (i.e., left, right, upward or downward) or radially with respect to a central axis Y that extends vertically and centrally through the mounting portion 111. See fig. 7 and 8. The mounting portion 111 may also include a central face 128, an annular ridge 130 having a first pin 132 and a second pin 134, an outer surface 136 having a third pin 138, and an edge face 140 adjacent to or extending through the latches 122, 124, 126. See fig. 7-10.

The mounting portion 111 may have a generally circular shape as shown in the end views shown in fig. 9 and 10. In various embodiments, the mounting portion 111 may comprise other shapes, such as oval, triangular, square or other rectangular, or other polygonal shapes. The general shape of the mounting portion 111 may be configured to match the general shape of a recess in the display 102 that mates with the mounting portion 111, thereby providing a keyed structure for the desired mating of the display 102 with the mounting portion 111. See fig. 14-17. The latches 122, 124, 126 may extend from a circular surface, such as the edge face 140, or from a straight surface (e.g., on the rectangular mounting portion 111).

Figure 7 shows an isometric view of the upper end of the gantry 106, the support arm 104, and the mounting portion 111. Fig. 8 shows a side view of these components. Fig. 9 shows an end view of the side of the mounting portion 111 facing the display, and fig. 10 shows an end view of the side of the mounting portion 111 facing the arm. FIG. 11 shows a side cross-sectional view of the mounting portion 111 taken along section line 11-11 in FIG. 9. Fig. 12 is an end view of the mounting portion 111 with the outermost display-facing surfaces (i.e., the central face 128, the ridges 130, and the outer surface 136) omitted to show details of the interior of the mounting portion 111.

The central face 128 of the mounting portion 111 may be a substantially flat portion that covers the mounting portion 111 of the magnetic assembly 142. See fig. 9 and 12. The magnetic assembly 142 may be substantially planar and arranged parallel to the central plane 128 within the mounting portion 111. The magnetic assembly 142 may include a first magnetic structure 144, a second magnetic structure 146, a third magnetic structure 148, a fourth magnetic structure 150, and a fifth magnetic structure 152. See fig. 12.

The first magnetic structure 144 may be positioned to be centrally aligned with the central axis Y of the mounting portion 111. The second through fifth magnetic structures may be positioned circumferentially spaced apart around the first magnetic structure 144. The first magnetic structure 144 may be circular, as shown, and in some cases may have another polygonal or elliptical shape. Thus, the second through fifth magnetic structures may be positioned around the circumference or perimeter of the polygon or ellipse of the first magnetic structure 144. In some embodiments, less than four additional magnetic structures are positioned around the first magnetic structure 144. For example, the first magnetic structure 144 may be the only magnetic structure, or there may be a total of two, three, or four magnetic structures including the first magnetic structure 144 centered on the other magnetic structure. In some cases, the first magnetic structure 144 may be omitted, and the second through fifth magnetic structures (or a subset thereof) may be provided separately.

The magnetic structures 144, 146, 148, 150, 152 may include magnetic attraction to other magnetic structures (e.g., 1302 or 1650/1652/1654 in fig. 13, 16, and 17). Accordingly, the magnetic structures 144, 146, 148, 150, 152 may include permanent magnets (e.g., rare earth magnets), electromagnets, ferrous materials, similar magnetic materials, and combinations thereof. The function of the magnetic structures 144, 146, 148, 150, 152 of the mounting portion 111 will be described in more detail below in connection with fig. 13 and 16-17.

The annular ridge 130 may extend in an axial direction (i.e., parallel to the central axis Y) away from the central face 128 and the outer surface 136. The ridge 130 may be configured to seat in a groove 1404 in the display 102 (see fig. 14). In some embodiments, the ridges 130 may be depressions and the grooves 1404 of the display 102 may be ridges, thereby reversing their role. When the ridge is positioned within the groove 1404, the ridge 130 can mechanically prevent the mounting portion 111 from translating laterally relative to the display 102. Thus, with the ridge 130 and the groove 1404 mated, a user can ensure that the display 102 is properly positioned on the mounting portion 111 and will not easily slide off the mounting portion 111 or apply radial pressure to the latches 122, 124, 126. In one embodiment, the ridge 130 may have an overall width/diameter or a maximum width/diameter and a minimum width/diameter that are each greater than the overall width/diameter of the magnetic assembly 142.

The first pin 132 may extend in an axial direction (parallel to the Y-axis) from the display-facing surface of the ridge 130. As shown in fig. 10 and 11, the first pin 132 may be in the shape of a bolt or bolt extending through the display-facing side of the mounting portion 111 and through the arm-facing side of the mounting portion 111. The first pin 132 may be located in a bushing 154 in the mounting portion 111 and may slide relative to the bushing 154 and relative to the mounting portion 111. As explained in further detail below, the first pin 132 may limit movement of the support arm 104 relative to the gantry 106 when the release mechanism 156 of the mounting portion 111 is operated.

The second pin 134 may extend in an axial direction from a display-facing surface of the ridge 130. The second pin 134 may be stationary relative to the ridge 130 and may mechanically interface with a second recess 1408 in the housing 1420 of the display 102, as explained in further detail below. See fig. 14.

The outer surface 136 may comprise a generally planar surface that is parallel to or coplanar with the central plane 128. The outer surface 136 may include a high friction material relative to the ridge 130 and relative to the central plane 128. For example, the outer surface 136 may include a silicone surface cover that generates relatively high friction when pressed against the display 102. The high friction material may help prevent relative sliding between the display 102 and the mounting portion 111 and may reduce scratching or damage of the rear surface of the display 102. Below the surface cover, the outer surface 136 may comprise a rigid material, such as a metallic material (e.g., steel or aluminum).

A third pin 138 may extend from the outer surface 136 in an axial direction. The third pin may retract axially into the outer surface 136 when the display 102 is rotated relative to the mounting portion 111. The third pin 138 may be configured to resist or prevent axial retraction in this manner when the support arm 104 is not in the raised position. Retraction of third pin 138 into outer surface 136 may be prevented unless release mechanism 156 is operated.

The edge face 140 may be a chamfer, chamfered or otherwise angled face around the outer surface 136. Thus, the edge face 140 may help guide or funnel the mounting portion 111 into the recess 1400 of the display 102, as explained in more detail below in connection with fig. 16 and 17.

The release mechanism 156 is shown in fig. 8, 10 and 12. Fig. 8 shows a side view, fig. 10 shows an outer end view, and fig. 12 shows an inner end view. The release mechanism 156 is shown protruding from the rear surface 158 of the mounting portion 111 in a manner that is easy to find by blind touch (i.e., by the user's hand) even when the user cannot look behind the display 102 to see the rear surface 158. In some embodiments, release mechanism 156 does not protrude or recess into rear surface 158. The release mechanism 156 is laterally slidable (i.e., slidable along axis X in fig. 10) relative to the mounting portion 111 between a first position, shown in fig. 10, and a second position at position 156-a in fig. 10.

The release mechanism 156 is operable to release the display 102 from the mounting portion 111 or release the display 102 from being locked in a lateral orientation relative to the mounting portion 111. The release mechanism 156 is coupled to a rotatable ring 162 within the mounting portion 111 via a pin 160. See fig. 12. Thus, sliding the release mechanism 156 to position 156-a in fig. 10 may cause the rotatable ring 162 to rotate about the central axis Y. The ramped surfaces 164, 166 of the rotatable ring 162 may engage portions of the first and third pins 132, 138 and may retract the pins as the rotatable ring 162 is rotated (or may allow the pins to retract) into the mounting portion 111. The ramped surfaces 164, 166 may prevent rotation of the ring 162 if the support arm 104 is not in its maximum raised position due to the first pin 132 being prevented from retracting by the locking member 204. See fig. 11 herein and its associated description.

The rotatable ring 162 may also include a first, second, and third latch- pin opening 168, 170, 172 in which the respective first, second, and third pins 174, 176, 178 of the first, second, and third latches 122, 124, 126 are located. The first latch pin opening 168 may have a radially angled surface 180. Thus, when the rotatable ring 162 is rotated counterclockwise in fig. 12, the first latch pin 174 may be pulled radially inward (i.e., toward the central axis Y while contacting the radially inclined surface 180). As the first latch pin 174 is pulled inward, the first latch 122 is pulled radially inward. As the rotatable ring 162 moves clockwise, the first latch pin 174 may slide back along the radially sloped surface 180 to the position shown in fig. 12 due to the radially oriented biasing device 182 acting on the first latch 122.

The second latch pin opening 170 may have a ramped surface 184 and a notch 186. Thus, as the rotatable ring 162 rotates counterclockwise in fig. 12, the second latch pin 176 may be pulled radially inward along the sloped surface 184. Similar to the first latch 122, when the second latch pin 176 is pulled inward, the second latch 124 is pulled radially inward.

However, once sufficient rotation of the rotatable ring 162 occurs, the second latch pin 176 may seat in the notch 186 due to the radially outwardly directed biasing force exerted on the second latch 124 by the biasing device 188. When the second latch pin 176 is seated in the notch 186, even if the rotatable ring 162 is biased to the position shown in fig. 12 by the circumferential biasing structures 190, 192, the rotatable ring 162 is prevented from rotating clockwise back to the position shown in fig. 12 by interference between the notch 186 and the second latch pin 176. However, if the second latch pin 176 moves radially inward, such as by the second latch 124 being forced radially inward by a portion of the recess of the display 102 (e.g., the lip 1456 in FIG. 14; see also FIGS. 18-20); the second latch pin 176 may move out of the notch 186 and the rotatable ring 162 may return to the position shown in fig. 12 due to the action of the circumferential biasing structures 190, 192.

The third latch pin opening 172 may have a circumferential surface 194, a first inner surface 196, and a second inner surface 198. When the rotatable ring 162 is rotated counterclockwise in fig. 12, the third latch pin 178 is movable within the third latch pin opening 172 along the circumferential surface 194. Unlike the first and second latch pin openings 168, 170, the third latch pin opening 172 does not radially retract the third latch 126 because the circumferential surface 194 does not radially tilt. Thus, when the rotatable ring 162 is rotated, the third latch 126 remains in the position shown in fig. 12. This may be beneficial because the third latch 126 is positioned at the vertical top and center of the mounting portion 111.

When the display 102 is mounted to the mounting portion 111 and the release mechanism 156 is operated, the first and second latches 122, 124 may be at least partially retracted relative to the edge face 140, thereby reducing the overall radius of the mounting portion 111 at the location of the first and second latches 122, 124 in a manner that allows the mounting portion 111 to be retracted from a recess in the display 102 that is smaller than the radius of the extended first and second latches 122, 124. If the third latch 126 were to retract in the same manner as the first and second latches 122, 124, the display 102 could potentially slip off of the mounting portion 111 because the radius of all of the latches 122, 124, 126 is smaller than the radius of the recess of the display 102. However, because the third latch 126 does not retract upon operation of the release mechanism 156, the third latch 126 may remain hooked over the recess of the display 102 (i.e., it may remain positioned under the lip structure of the recess, as explained in further detail below), and the third latch may thereby prevent accidental disconnection of the display 102 from the mounting portion 111 by holding the display 102 "hooked" in place.

With the release mechanism 156 triggered into position 156-a, the first and second latches 122, 124 are radially retracted, and the third latch 126 may be partially radially retracted when the display 102 is pulled away from the mounting portion 111. The third latch 126 is radially retractable because the third latch pin opening 172 is sized to provide space for the third pin 178 to translate radially inward up to the second inner surface 198. Since the third latch 126 is in contact with a lip structure surface of the recess of the display 102 (e.g., the lip 1456 in fig. 14 and 18-20) and thus slides at least partially radially inward, the third latch 126 may retract radially in a similar manner as the first and second latches 122, 124.

The second inner surface 198 may be spaced radially outward relative to the first inner surface 196 to limit the amount of radial retraction of the third latch 126 when the mounting portion 111 is pulled from the display 102. The small protrusion of the third latch 126 relative to the edge face 140 may require the user to pull laterally along the central axis Y while also pulling on the display 102 when pulling from the mounting portion 111The display 102 is rotated up or down (similar to force F in FIG. 1)₁) So that the display 102 is completely removed from the mounting portion 111. This additional upward movement may help to ensure that the user intentionally removes the display 102 when the release mechanism 156 is operated, and limit the ability of the display 102 to inadvertently slide off the mounting portion 111 in a horizontal direction.

The first inner surface 196 of the third latch pin opening 172 may be radially closer to the central axis Y relative to its second inner surface 198 such that the third latch 126 may be fully radially retracted into the mounting portion 111 when the display 102 is mated to the mounting portion 111. Thus, the user may push the display 102 directly (i.e., only horizontally) onto the mounting portion 111 along the central axis Y without first hooking or hanging the display 102 onto the third latch 126.

The latches 122, 124, 126 may comprise a variety of materials. In some embodiments, the radially outermost portion 200 of the latches 122, 124, 126 may comprise a non-marking and low friction material, such as a plastic (e.g., nylon), an elastomer (e.g., rubber), or the like. Thus, when the latches 122, 124, 126 slide against the surface of the display 102, they may not scratch the facing of the display 102 as easily and may slide against the display 102 with low friction. Other interior surfaces of the latches 122, 124, 126 may include low friction materials, including, for example, pins 174, 176, 178 and flow passages (e.g., 202) that will contact or slide against surfaces within the mounting portion 111. Other structures in the latches 122, 124, 126 may include high strength load bearing materials such as steel or other ferrous alloys to resist bending or breaking.

As shown in fig. 11, the first pin 132 may contact the locking member 204 within the support arm 104 when the support arm 104 is in an at least partially lowered position (e.g., as shown in fig. 2). When the support arm 104 is moved to the raised position (e.g., as shown in fig. 4), the housing 206 and the block 208 of the support arm 104 may rotate about the axis 120. At a sufficiently high angle of the support arm 104, the block 208 rotates out of contact with the inner surface 210 of the locking member 204, allowing the inner surface 210 of the locking member 204 to move along the axis of the first pin 132 as the first pin 132 moves toward the axis 120 and presses the locking member 204 inward. When the release mechanism 156 is operated and the inclined surface 164 rotates and slides the first pin 132 longitudinally, the first pin 132 may push against the locking member 204.

With the support arm 104 in the raised position and the release mechanism 156 triggered, the first pin 132 and the locking member 204 move rearward relative to the rear surface 158, and contact between the bottom surface 212 of the locking member 204 and the block 208 prevents the support arm 104 from rotating back to the lowered position. Thus, when the first pin 132 and the locking member 204 move rearward, the display 102 cannot translate downward relative to the stand 106. For this reason, the first pin 132 may be referred to as a locking pin. When the release mechanism 156 is moved back to its default/biased position (as shown in fig. 12), the first pin 132 and the locking member 204 may return to the position shown in fig. 11, allowing the block 208 to rotate about the pivot axis 120 to a position behind the locking member 204 (i.e., a position opposite the first pin 132) and also allowing the entire support arm 104 to rotate. The locking member 204 may include an elongated central opening 214 configured to allow the locking member 204 to translate relative to a central shaft 216 positioned about the pivot axis 120.

Fig. 13 is a diagram illustrating additional detail regarding the magnetic assemblies 1300, 1302 that may be positioned in the display 102 and the mounting portion 111. One of the magnetic assemblies 1300, 1302 may be positioned in the display 102 and the other may be positioned in the mounting portion 111. For example, the magnetic assembly 1300 may include the magnetic structures 144, 146, 148, 150, and 152 in the mounting portion 111. See fig. 12.

The magnetic assemblies 1300, 1302 may include central magnetic structures 1304, 1308 each surrounded by peripheral magnetic structures 1306, 1310. The central magnetic structures 1304, 1308 may have respective magnetic axes N₁、N₂The magnetic axis is configured to be parallel to or coaxial with the central axis Y of the mounting portion 111. Thus, the magnetic axis N₁、N₂May be coaxial or parallel to each other.

One of the central magnetic structures 1304 may include along the magnetic axis N₁Has a first polarity (i.e., north polarity as shown in fig. 13) and another outward end or faceThe central magnetic structure 1308 may include along its axis N₂Having an opposite second polarity (i.e., south polarity as shown in fig. 13). The outward ends or faces of the central magnetic structures 1304, 1308 can be configured to face each other when the display 102 is mounted to the mounting portion 111. See also fig. 16-17 and their associated description herein. Thus, when the magnetic assemblies 1300, 1302 are in proximity to each other, the central magnetic structures 1304, 1308 may attract each other. To this end, when the display 102 is mounted to the mounting portion 111, the central magnetic structures 1304, 1308 may exert a magnetic force to help a user guide the display 102 and the mounting portion 111 into contact with each other. This may be beneficial when the user cannot see the mounting portion 111 and the back of the display 102, such as when the user blindly mounts the display 102 to the mounting portion 111 (i.e., mounting is done only if the viewing side of the display 102 is visible and the back side of the display 102 is not visible).

The peripheral magnetic structures 1306, 1310 may each include a magnetic axis N₁、N₂Perpendicular to the respective peripheral magnetic axes of intersection. These peripheral magnetic axes are shown by arrows in fig. 13, 16 and 17. In some embodiments, all peripheral magnetic axes of the peripheral magnetic structures 1306, 1310 are coplanar and the magnetic axis N is₁、N₂Perpendicularly intersecting the plane of the peripheral magnetic axis. The peripheral magnetic axis may be referred to as a radially oriented pole or a radially oriented pole axis of the peripheral magnetic structure 1306, 1310. In the magnetic assembly 1300, the peripheral magnetic axis may be at a radially inward end (relative to the magnetic axis N) of each of the peripheral magnetic structures 1306₁) Has a south polarity and may have a north polarity at its radially outward end. The peripheral magnetic structure 1310 may have an opposite polarity relative to the peripheral magnetic structure 1306. Thus, in each magnetic assembly 1300, 1302, the peripheral magnetic structures 1306, 1310 may have a central magnetic structure 1304, 1308 with an outward end polarity opposite the radially inward polarity of its respective peripheral magnetic structure 1306, 1310.

The combined central magnetic structure 1304 and peripheral magnetic structure 1306 may form a magnetic flux An amount of magnetic flux that helps align the magnetic axis N when approached by the central magnetic structure 1308 and the peripheral magnetic structure 1310₁、N₂. The central magnetic structures 1304, 1308 can provide a longitudinal pulling force toward each other, and the peripheral magnetic structures 1306, 1310 can provide a longitudinal pulling force in addition to a lateral guiding force that causes each of the peripheral magnetic structures to attempt to align with a corresponding peripheral magnetic structure on the opposing magnetic assembly. Thus, the magnetic assemblies 1300, 1302 may be directed toward each other in both the longitudinal and lateral/radial directions. Thus, a user carrying the display 102 may feel that the magnetic assemblies 1300, 1302 pull the display 102 toward the mounting portion 111 while also pulling the magnetic axis N₁、N₂Pulled into alignment.

Fig. 14-15 illustrate features of the recess 1400 in the rearward surface 110 of the display 102. Fig. 14 is an isometric view of a recess 1400. The depression 1400 may include a central plane 1402, a groove 1404 having a first depression 1406 and a second depression 1408, an outer surface 1410 having a third depression 1412 and a fourth depression 1414, and at least one laterally extending depression 1416. Fig. 15 illustrates a detailed isometric view of a portion of the recess 1400 at a bottom end portion 1418 of the laterally extending recess 1416, where the isometric view of fig. 15 is a view at block 15 in fig. 14 from a different perspective than fig. 14.

The central plane 1402 of the recess 1400 may be a substantially flat portion that covers the magnetic component (e.g., 1300 or 1302). See fig. 13-14. The magnetic components of the display 102 may be substantially planar and arranged within the housing 1420 of the display 102 parallel to the central plane 1402. The central plane 1402 may have a shape (e.g., circular) and size corresponding to the shape and size of the magnetic assembly it covers, similar to the central plane 128.

The groove 1404 may be annular and similar in size to the annular ridge 130 of the mounting portion 111. The groove 1404 may be configured to receive the ridge 130, as described above in connection with fig. 7-9. The grooves 1404 may comprise a strong load bearing material, such as steel or another iron alloy.

The first recess 1406 may extend circumferentially around and longitudinally into the inner surface 1422 of the groove 1404. A first recess 1406 may be positioned on the groove 1404 to receive the first pin 132 of the mounting portion 111. The first pin 132 may be positioned in the first end 1424 of the first recess 1406 when the display 102 is in the landscape orientation. In this position, the first pin 132 may extend completely from the display-facing surface of the ridge 130 (e.g., the position shown in fig. 11). Thus, the support arm 104 may be freely pivotable between the raised position and the lowered position because the locking member 204 is not displaced into the position of the interference block 208 by the first pin 132. See also fig. 11 herein and its related description.

The first recess 1406 can include a ramped surface 1426 between its first and second ends 1424, 1428. The second end 1428 of the first recess 1406 may be shallower relative to the depth of the first end 1424 when compared to the inner surface 1422. Thus, when the block 208 prevents the first pin 132 and the locking member 204 from moving, the display 102 cannot rotate from a landscape orientation to a portrait orientation because the first pin 132 contacts the ramp surface 1426, but cannot retract into the ridge 130. However, with the support arm 104 in the raised position and the release mechanism 156 triggered, the first pin 132 can retract upon contacting the ramp surface 1426. Thus, the first pin 132 may slide into contact with the second end 1428 of the first recess 1406. When in contact with the second end 1428, the first pin 132 cannot extend back out of the ridge 130, and thus the bottom surface 212 of the locking member 204 prevents rotation of the block 208 of the support arm 104 and the housing 206. To this end, the support arm 104 cannot rotate to the lowered position when the display 102 is in the portrait orientation (which corresponds to the first pin 132 contacting the second end 1428). To return to the lowered position of the support arm 104, the display 102 must be rotated to a landscape orientation in which the first pin 132 contacts or is proximate to the first end 1424, as in this case the bottom surface 212 of the locking member 204 may move out of the block 208.

The support arm 104 may require movement of the locking member 204 in order to retract the first pin 132 into the mounting portion 111. The display 102 cannot be removed and the release mechanism 156 cannot be operated unless the support arm 104 is in its maximum raised position. The support arm 104 may include a counterbalance mechanism that applies a force to move the mounting portion 111 upward to counterbalance the weight of the display 102. With the support arm 104 in the most raised position, the balancing does not require releasing energy and moving the support arm 104 upward when the display 102 is removed from the mounting portion 111.

The second recess 1408 can be positioned on the trench 1404 opposite the first recess 1406. Thus, the second recess 1408 may be configured to receive a second pin 134 positioned opposite the first pin 132 on the ridge 130. When mounting portion 111 is positioned in recess 1400, display 102 may rotate between the landscape orientation and the portrait orientation as second pin 134 moves within second recess 1408. In the transverse orientation, second pin 134 is positioned near first end 1430 of second recess 1408, and in the longitudinal orientation, second pin 134 is positioned near second end 1432. The shape of the second recess 1408 may ensure that the display 102 rotates in one direction only when moving from landscape to portrait orientation (e.g., counterclockwise when viewed from the front of the display 102) and rotates in the opposite direction when moving from portrait to landscape. Attempting to rotate the display 102 in the wrong direction may result in interference between one side of the second recess 1408 and the second pin 134. The circumferential length of the second recess 1408 may be about one-quarter of the center circumference of the groove 1404, which corresponds to about 90 degrees of rotation of the display 102 relative to the mounting portion 111. Second recess 1408 and second pin 134 may be referred to as pin-and-slot features for controlling rotation of the display relative to the mounting portion.

The outer surface 1410 may include a substantially planar surface that is parallel to or coplanar with the central plane 1402. The outer surface 1410 may include a high friction material relative to the grooves 1404 and relative to the central plane 1402. For example, the outer surface 1410 may include a silicone or rubber elastomer covering that generates relatively high friction when pressed against the outer surface 136. The high friction material may help prevent relative sliding between the display 102 and the mounting portion 111 and may reduce scratching or damage of the rear surface of the display 102. The high friction material may be referred to as a friction pad and may be attached to the outer surface 1410. In addition to the recesses 1412, 1414, which may comprise steel, the underlying material of the housing 1420 at the outer surface 1410 may comprise aluminum.

The third recess 1412 may be positioned on the outer surface 1410 and may be substantially similar in size to the third pin 138. Thus, the third recess 1412 may receive the third pin 138 when the display 102 is in the landscape orientation. The sidewalls of the third recess 1412 may prevent the display 102 from rotating to the portrait orientation due to contact with the third pin 138. Thus, when a user desires to rotate the display 102 to a portrait orientation, the release mechanism 156 may be operated to move the sloped surface 166 (see fig. 12) in a manner that causes the third pin 138 to retract relative to the outer surface 136. Retraction of the third pin 138 may remove the third pin 138 from the third recess 1412, thereby removing its ability to prevent rotation of the display 102 relative to the central axis Y.

A fourth recess 1414 is also positioned on the outer surface 1410 at a location circumferentially spaced from the third recess 1412. The fourth recess 1414 may be positioned at a circumferential distance of about one-quarter of the center circumference of the outer surface 1410, which corresponds to about 90 degrees of rotation of the display 102 relative to the mounting portion 111. Thus, because the third recess 1412 is aligned with the third pin 138 in the transverse orientation, the fourth recess 1414 is aligned with the third pin 138 in the longitudinal orientation because the longitudinal orientation is rotated approximately 90 degrees relative to the transverse orientation. In this way, the third pin 138 may prevent the display 102 from rotating relative to the mounting portion 111 when the display 102 is in the portrait orientation. To move the display 102 back to the landscape orientation, the release mechanism 156 may be triggered to retract the third pin 138 from the fourth recess 1414, such that the display 102 may return to a position where the third pin 138 is again in the third recess 1412.

The at least one laterally extending recess 1416 (i.e., the lateral recess) can extend circumferentially around substantially the entire circumference of the recess 1400. The lateral recesses 1416 can receive the latches 122, 124, 126 when the display 102 is mated with the mounting portion 111.

Fig. 16-17 show diagrammatic side views of mounting portion 1611 interacting with recess 1600 in housing 1620 of a display. Some features of mounting portion 1611 and housing 1620 are omitted or simplified in these views as compared to mounting portion 111 and housing 1420. However, mounting portion 111 and housing 1420 may operate similarly to mounting portion 1611 and housing 1620. As recess 1600 approaches mounting portion 1611, magnetic structures 1644, 1646, 1648, 1650, 1652, 1654 may attract one another and may align the center of mounting portion 1611 with the center of recess 1600. The latches 1622, 1624 of the mounting portion 1611 may extend relative to the sides of the mounting portion 1611. The latch 1622 may correspond in function to the latches 122, 124, and 126.

The mounting portion 1611 may contact the housing 1620 with the latches 1622, 1624 contacting at least one flange or lip 1656. Lip 1656 may extend radially inward above laterally outward extending recess 1616. The front surface 1658 of the latches 1622, 1624 may be angled or curved in a manner such that the latches 1622, 1624 may retract relative to the housing of the mounting portion 1611 when there is contact between the front surface 1658 and the lip 1656. In some embodiments, front surface 1658 slopes rearward at an angle of about 15 degrees relative to the plane of central plane 128. Front face 1658 and edge face 140 may be sloped in a manner wherein if those surfaces 140, 1658 contact the outer rim of lip 1656 off-center, their narrowed center diameter may be aligned with the center of recess 1600 similar to funnel guide mounting portion 1611.

As the mounting portion 1611 continues into the recess 1600, the latches 1622, 1624 are fully retracted until they are at an axial depth in the recess 1600 corresponding to the laterally outwardly extending recess 1616. At this depth, the latches may spring back radially outward due to biasing structures (e.g., 182, 188) acting on the latches. Thus, the latches 1622, 1624 may retain the mounting portion 1611 within the recess 1600 by mechanical interference with the lip 1656. The laterally outwardly extending recess 1616 may extend circumferentially around the recess 1600 below the lip 1656 such that the housing 1620 may rotate relative to the mounting portion 1611 while the latches 1622, 1624 hold the display to the mounting portion 1611. Ridge 1630 and groove 1604 may also mate with each other when mounting portion 1611 is fully inserted into recess 1600 in a manner that prevents lateral sliding of mounting portion 1611 relative to lip 1656.

When the display 102 is mated with the mounting portion 111, the latches 122, 124, 126 may be positioned in the lateral recess 1416 below the lip 1456 extending around the recess 1400. See fig. 14-15. The display 102 is rotatable about a central axis Y with the latches 122, 124, 126 secured by the lip 1456.

Magnetic structures 1644, 1646, 1648, 1650, 1652, 1654 may also be in a low or minimal potential (i.e., close to each other) state when mounting portion 1611 is inserted into recess, and those magnetic structures may provide resistance to longitudinal retraction of mounting portion 1611 from recess 1600. As shown in fig. 17, the central magnetic structure 1644, 1650 and the peripheral magnetic structure 1646, 1648, 1652, 1654 may be positioned proximate to a similar structure having opposite polarity. Ferrous plates 1660 may be positioned adjacent to the magnetic structures 1650, 1652, 1654 on their inner sides. The ferrous plates 1660 may at least partially help redirect the magnetic flux of the magnetic structures 1650, 1652, 1654 away from the interior of the display housing 1620 and outward toward the recess 1600. Similar ferrous plates may be positioned on the inside of magnetic structures 1644, 1646, 1648 of mounting portion 1611 to perform similar flux-forming functions.

As shown in fig. 18, the second latch 124 may be positioned below the latch retaining surface 1802 of the lip 1456 when the mounting portion 111 is fully inserted into the recess 1400. As described above, operation of the release mechanism 156 can retract the latches 122, 124. The second latch 124 may have its pin 176 retained in the notch 186 in a manner that prevents the release mechanism 156 from being reset via the biasing structures 190, 192. Accordingly, the lip 1456 can include an inwardly facing beveled portion 1800 as shown in the diagrammatic side cross-sectional views of fig. 18-20.

The latches 124 may be partially retracted radially inward by operation of the release mechanism 156, and this partial retraction may move the latches 124 from a radially outer position where the latches 124 contact a non-inclined latch retention surface 1802 (see fig. 18) to a position proximate to the inclined portion 1800 (see fig. 19). With the latch 124 contacting the ramped portion 1800 and a longitudinal retraction force applied to the display 102, the lip 1456 can urge the latch 124 radially inward further than the release mechanism 156, thereby moving the pin 176 radially inward and allowing the release mechanism 156 to reset. However, once the second latch 124 is in contact with the inclined portion 1800, the first latch 122 has contacted the lip 1456. Thus, the latches 122, 124 are constrained by the lip 1456 from extending back radially outward under the lip 1456. See fig. 20. Thus, the user can pull the display 102 away from the mounting portion 111 by pulling along the central axis Y while pivoting the top of the recess 1416 upward and away from the third latch 126. In this way, removal of the display 102 from the mounting portion 111 automatically resets the release mechanism 156. Thus, the release mechanism 156 can be re-latched to the display immediately after removal of the display (e.g., 102).

Referring again to fig. 14-15, the lateral recess 1416 can have a bottom end portion 1418, wherein the lateral recess 1416 extends not as far from the central axis Y as other portions of the lateral recess 1416. When the display 102 is positioned in the landscape orientation, the second latch 124 is positioned in the lower left section of the lateral recess 1416, as shown in fig. 14. When ready to rotate to the longitudinal orientation, the user may trigger the release mechanism 156, partially retracting the second latch 124 until the second pin 176 is within the notch 186 and the first and third pins 132, 138 are retracted. Thus, the display 102 is rotatable about the central axis Y. With this movement, the bottom end portion 1418 can be rotated clockwise in fig. 14 by about 90 degrees while the second latch 124 remains stationary. The bottom end portion 1418 can have a first ramp 1458 so that when the display 102 is rotated to a portrait orientation, the first ramp contacts the second latch 124. The first ramp 1458 is gradually pushed into the second latch 124 in a manner that moves the second pin 176 inwardly relative to the notch 186 and releases the rotatable ring 162. Thus, the release mechanism 156 may automatically reset (via the biasing structures 190, 192) when the display 102 is rotated from the landscape orientation to the portrait orientation. With the release mechanism 156 reset, the latches 122, 124 may automatically re-extend and hold the display 102 on the mounting portion 111 in the portrait orientation.

In a similar manner, when the display 102 is in the portrait orientation, the release mechanism 156 may be operated to retract the third pin 138 in a manner that allows the display 102 to move about the central axis Y while still engaging the mounting portion 111. The trigger release mechanism 156 again traps the pin 176 in the notch 186. Thus, rotating the second ramp 1460 of the bottom end portion 1418 of the lateral recess 1416 against the second latch 124 pushes the second latch 124 and resets the release mechanism 156. In other words, the secondary ramp 1460 moves from a position on the left side of fig. 14 to the bottom side of fig. 14, and in this movement, contacts and pushes the secondary latch 124 radially inward. Thus, the release mechanism 156 may automatically reset when the display 102 is rotated from the portrait orientation to the landscape orientation. With the release mechanism 156 reset, the latches 122, 124 can automatically re-extend and hold the display 102 on the transversely oriented mounting portion 111.

Fig. 21 shows an isometric view of the support arm 2104 with an alternative embodiment of the mounting portion 2111. In this embodiment, the mounting portion 2111 includes four circumferentially spaced and radially retractable latches 2122, which may function similar to the first latch 122. The mounting portion 2111 also has a non-retractable latch 2170 positioned at the top end. Thus, four retractable latches can be implemented on the mounting portion 2111. Not all latches are equally spaced as shown by non-retractable latch 2170 being closer to two of the other latches 2122. Non-retractable latch 2170 may require rotation or tilting of the display relative to mounting portion 2111 in order to rotate latch 2170 under a lip in the rear recess of the display. In some variations, the mounting portion 2111 can include more/less than four retractable latches 2122.

Fig. 22 illustrates an isometric view of a support arm 2204 having an alternative embodiment of a mounting portion 2211. In this embodiment, the mounting portion 2211 can include a central protrusion 2230 having a side surface 2232 in which a set of six radially retractable pins 2234 are positioned. The set of pins 2234 may be radially retracted in response to actuation of a release mechanism similar to mechanism 156. The pin 2234 may have a rounded end surface, wherein insertion of the protrusion 2230 into a similarly sized recess in the display may cause the pin 2234 to be pressed inward by a lip of the recess. The pins 2234 may be biased radially outward, wherein once the protrusions 2230 are fully inserted into the recesses, the pins 2234 may return to the extended position shown in fig. 22. In some configurations, the pin 2234 can be a ball bearing, and the pin 2234 can thus roll into place on the protrusion 2230 in a manner that reduces friction between the protrusion 2230 and the pocket lip into which the protrusion 2230 is inserted.

Fig. 23-30 illustrate various features of another embodiment of a display mounting apparatus. The display mounting apparatus may be referred to as a display mounting adapter 2300 that allows a display having the features of the display 102 to be attached to and supported by the universal support arm. For example, the display mounting adapter 2300 may be used to mount the display 102 to a standard VESA mount having four mounting points spaced apart at predetermined or standardized locations (e.g., a 200mm x 200mm square, a 400mm x 400mm square, a 400mm x 200mm rectangle, or another standard size). Fig. 23 shows an inside (i.e., front or forward) view of the display mounting adapter 2300, and fig. 24 shows an outside (i.e., rear or rearward) view of the display mounting adapter.

The mounting points of the universal support arm may be spaced apart in a manner that corresponds to the mounting points 2302 on the mounting plate 2304 of the mounting adapter 2300. See fig. 24. The mounting point 2302 may be a threaded opening in the mounting plate 2304 (or in a socket 2306 of the mounting plate) to receive a fastener extending through or from the universal support arm.

The display mounting adapter 2300 may include a mounting portion 2311 having a shape comparable to the mounting portion 111 and configured to extend into a similar recess (e.g., 1400) of the display 102. The mounting portion 2311 may include three latches 2312 that are radially movable between an unlatched or retracted configuration (as shown in fig. 23-26) and a locked or extended configuration (partially shown in fig. 29). In the locked or extended configuration, the latch 2312 extends from an edge face 2340 of the mounting portion 2311, similar to the latches 122, 124, 126 of fig. 9 extending from the edge face 140. Thus, the latch 2312 may be positioned within the recess 1400 and may be retained by the lip 1656. When in the unlocked or retracted configuration, the latch 2312 may be retracted to a radial dimension that allows the mounting portion 2311 to be removed from the recess 1400.

The mounting portion 2311 may include a front plate 2314 (see fig. 23) and a back plate 2316 (i.e., a rear case; see fig. 24). The front plate 2314 may include a ridge or retaining ring 2318 protruding forward from the inner face 2320 and the outer face 2322, the ridge or retaining ring having a size and function similar to the corresponding features of the mounting portion 111. The outer face 2322 may be covered with a high-friction material. The front plate 2314 may have an opening through which the two timing protrusions 2324, 2326 may extend.

Fig. 25 illustrates an isometric view of the display mounting adapter 2300 with the front plate 2314 omitted. Fig. 26 shows a front end view of the mounting portion 2311 with the front plate 2314 and the two lower latches 2312 omitted. The latches 2312 may each include an outer body 2328, an inner body 2330, and a pair of biasing devices 2332. The latch 2312 may interact with a rotatable cam 2334 at the center of the mounting portion 2311, as described below.

Rotatable cam 2334 may have a set of radially spiraling cam openings 2336, with one cam opening 2336 provided for each latch 2312. The inner body 2330 of the latch 2312 may have a cam follower rod 2338 extending longitudinally inward from the inner body 2330 into and through a cam opening 2336 (see fig. 27, which shows a rear isometric view of the inner body 2330). The follower rod 2338 is shown in the lower right portion of fig. 26 isolated from the rest of its associated inner body to illustrate its interaction with the cam opening 2336.

Upon rotation of the rotatable switch 2342 on the back of the mounting plate 2304, the cam 2334 may rotate about the longitudinal axis (similar to axis L) of the mounting portion 2311. See fig. 24. The rotatable switching member 2342 is rotatable between a first unlocked position (shown in fig. 24) and a second locked position that is rotated 90 degrees clockwise about the longitudinal axis with respect to the first unlocked position. Cam 2334 is in the unlocked position in fig. 26 and in the locked position in fig. 29.

Each cam opening 2336 may have a width sufficient to receive a diameter or width of a follower bar 2338. As the cam 2334 rotates, the follower bar 2338 may contact the sides of the spiral shape of the cam opening 2336 and slide radially inward or outward along the cam opening 2336. Counterclockwise motion of cam 2334 (as shown in fig. 26) can move follower bar 2338 (and thus inner body 2330 of latch 2312) radially outward, and clockwise motion of cam 2334 (as shown in fig. 29) can move follower bar radially inward. Cam openings 2336 may each include a locking end 2344 and an unlocking end 2346. When follower lever 2338 is positioned at locking end 2344, latch 2312 may be in an extended or locked position (as shown in fig. 29), and when follower lever 2338 is at unlocking end 2346, latch 2312 may be in a retracted or unlocked position.

Movement of the inner body 2330 is defined by movement of the follower rod 2338 on the inner body 2330 relative to the cam opening 2336 and by interference with a post 2348 extending through a guide slot 2350 on the inner body 2330. See fig. 26-27. Inner body 2330 may also contact a pair of biasing devices 2332 that bias outer body 2328 of each latch 2312 away from inner body 2330. The biasing device 2332 may also ensure that the inner body 2330 is biased into contact with the inner radial surface of each cam opening 2336.

At the unlocking end 2346 of each cam opening 2336, detents 2352 may be formed on radially inward surfaces of the cam openings 2336. Accordingly, when the cam 2334 is rotated by the rotatable switching member 2342, the cam followers 2338 may slide along the inner radial surface of each cam opening 2336 while gradually moving radially outward. Upon reaching the unlocking end 2346, the cam followers 2338 may be biased and move slightly radially inward into the detents 2352. The biased movement of cam follower 2338 may provide a "click" feel or similar feedback to the user rotating rotatable switch 2342 to indicate, by touch or tactile vibration, that cam 2334 has been fully rotated to its extreme locked rotational position. The detent 2352 can also provide some slight resistance to rotating the cam 2334 back to the unlocked rotational position. Rotating the cam 2334 toward the unlocked position may require the user to input sufficient torque to the switch 2342 to cause the cam follower 2338 to overcome the radially inwardly directed biasing force applied by the biasing apparatus 2332 so that it moves radially outward from the detent 2352 and into the remainder of the cam opening 2336.

Movement of the inner body 2330 and the biasing force applied by the biasing device 2332 may control movement of the outer body 2328 of each latch 2312. The outer body 2328 may translate radially and may each be constrained to only translate radially by a circular pin 2354 on the back plate 2316 that fits within a narrow slot 2356 on the outer body 2328 and a second diamond-shaped pin 2358 on the back plate 2316 that fits within a second wider slot 2360 on the outer body 2328. See fig. 25-26 and 29. The circular pin 2354 may extend through the cam 2334.

Inner body 2330 may be positioned within a bore or recess of outer body 2328. Inner body 2330 may contact sidewall 2362 of the aperture when it is moved from the locked position to the unlocked position, thereby urging outer body 2328 radially inward as it is moved radially inward. Inner body 2330 may thus move outer body 2328 inwardly to the unlocked position. Inner body 2330 may allow for a small amount of extension of bias device 2332 as the outer body approaches sidewall 2362, as shown by comparing the length of bias device 2332 in fig. 26 and 29.

The outer body 2328 may be constantly biased radially outward away from the center of the mounting portion 2311 by a biasing apparatus 2332, and may be pulled radially inward as the inner body 2330 moves radially inward. Thus, the radial distance from the central longitudinal axis of the mounting portion 2311 to the unlocking end 2346 may be small enough to move the inner body 2330 into contact with the outer body 2328. If the radial distance is not small enough, the inner body 2328 may "float" within the outer body 2328 without the outer body 2328 moving. This "floating" feature may advantageously prevent the outer body 2328 from retracting radially inward when the rotatable switching piece 2342 is rotated only a small amount from the locked position to the unlocked position. Conversely, in order for inner body 2330 to be pulled far enough to contact side wall 2362 and begin to retract outer body 2328, switch 2342 needs to be rotated a sufficient portion of its total travel range.

Each latch 2312 may also have a pair of bosses 2364 that extend through the outer body 2328. Tabs 2364 may be the location where the fasteners engage front and back plates 2314 and 2316. The boss 2364 may extend through the outer body 2328 without contacting the outer body 2328. Bosses 2364 may be positioned by outer body 2328 to ensure that the bosses are close enough to each other to limit the bending of front plate 2314. When display mounting adapter 2300 is in the locked position, latch 2312 may extend under a flange or lip of the display recess. If the adapter 2300 is pulled longitudinally away from the display recess when in the locked state, the latch 2312 may contact the flange or lip and, thus, may mechanically interfere and prevent the adapter 2300 from retracting. The latch 2312 is sandwiched between the front plate 2314 and the back plate 2316, so an attempt to retract from the display recess can apply a force to the outer body 2328, causing the outer body 2328 to contact the front or back plate. By having the bosses 2364 near each other and extending through the outer body 2328, the force applied to the front or back plate by the outer body 2328 is less likely to sufficiently bend or flex the front or back plates 2314, 2316 in a manner that could break the plates or cause the outer body 2328 to slip out from between the plates. Accordingly, the width between the bosses 2364 may be less than the overall lateral width of the outer body 2328 through which the bosses extend.

Cam 2334 may also be biased at an extreme unlocked position. Fig. 28 shows a side cross-sectional view of the cam 2334 and back plate 2316 at section line 28-28 in fig. 26. The rearward surface 2366 may have recessed detents 2368 therein that are configured to receive biasing balls 2370 that are received by the back plate 2316, with the biasing devices 2372 being located in the back plate recesses 2374.

Fig. 30 shows a similar cross-sectional view (taken along section line 30-30 in fig. 29) where when cam 2334 is not in the unlocked position (e.g., it is in the locked position), recessed detent 2368 has been rotated out of alignment with ball 2370 such that ball 2370 is retracted relative to the position shown in fig. 28. Thus, when the user rotates the switch 2342 out of the unlocked position (e.g., to the position of fig. 30), the user must apply sufficient torque to the switch 2342 to overcome the biasing force provided to the ball 2370 by the biasing device 2372 and retract the ball 2370 into the back plate 2316 out of the recessed detent 2368 and into contact with the flat portion of the rearward surface 2366. In this way, the user may feel a "bump" or "click" feedback when moving to or away from the extreme unlocked position caused by movement of ball 2370 relative to cam 2334. Additionally, the biasing ball 2370 may require a minimum torque to be applied to the switch 2342 in order to move out of the unlocked position.

Ball 2370, biasing device 2372, and depression 2374 may be disposed at a variety of points around cam 2334. In some embodiments, there are three such biasing features in the back plate 2316 and three corresponding recessed detents 2368 in the cam 2334. The detents 2368 may be circumferentially spaced about the circumference of the cam 2334 at positions approximately 120 degrees apart from each other.

Similar to the biasing device 2372, a biasing device (not shown) may bias the second timing protrusion 2326 away from the back plate 2316 in a longitudinal direction (i.e., toward the display recess 1400). Accordingly, the second timing protrusion 2326 may be biased into contact with a surface of the fourth recess 1414 of the display housing 1420. Thus, the second timing protrusion 2326 and the fourth recess 1414 can provide a path for static electricity to pass between the adapter 2300 and the display housing 1420 (i.e., chassis ground) by continuously contacting each other when the adapter 2300 is installed, despite dimensional variations due to manufacturing tolerances and movement between devices. In some embodiments, similar to the biasing device 2326, the first timing protrusion 2324 may also be biased in a longitudinal direction away from the back plate 2316. Accordingly, first timing protrusion 2324 may be biased into contact with a surface of third recess 1412. Bushing 2329 may laterally reinforce and longitudinally guide movement of first timing protrusion 2324 and second timing protrusion 2326.

In some embodiments, display mounting adapter 2300 can include magnetic component 142. In some cases, the magnetic component 142 may be omitted. The magnetic component 142 may be optional because the display mounting adapter 2300 may be attached to the display 102 when the display 102 is stationary (e.g., down above a support surface) rather than being carried by a user to mount to the display mounting adapter 2300. Alternatively, the magnetic assembly 142 can be included such that when the display 102 is moved to latch onto the display mounting adapter 2300, the universal support arm can have the display mounting adapter 2300 already positioned thereon.

Fig. 31 shows a front end view of another embodiment of the mounting portion 3111 of the support arm 3104 (see fig. 32) with some components omitted and the mounting portion in a locked state. Some components (such as the front plate) are omitted and some have been simplified for this illustration. The parts of the mounting portion 3111 having names corresponding to the parts of the mounting portion 111 described above may have corresponding functions.

In fig. 31, the rotatable ring 3162 may include a radial unlocking protrusion 3101 configured to rotate about the longitudinal axis (i.e., L) of the mounting portion 3111 upon operation of the release mechanism (e.g., 156). Thus, the radial unlocking protrusion 3101 may be rotated from a position out of contact with the retractable pin 3138 (as shown in fig. 31) to a position in contact with the pin 3138 (as shown in fig. 33). The rotatable ring 3162 may be biased into the rotational position shown in fig. 31 by a biasing device similar to the devices 190, 192.

The retractable pin 3138 may comprise an engagement surface 3139 configured to contact the unlocking protrusion 3101. In some embodiments, the engagement surface 3139 may be a rounded, ramped, or sloped surface, wherein as the unlocking protrusion 3101 comes into contact with the engagement surface 3139, the retractable pin 3138 may be gradually pushed longitudinally rearward (i.e., may retract relative to the front plate) in a manner similar to the way the third pin 138 retracts due to engagement with the sloped surface 166. The retractable pin 3138 may be biased in a longitudinally forward direction, wherein rotation of the unlocking protrusion 3101 out of contact with the engagement surface 3139 may allow the retractable pin 3138 to return to its default, forwardly extended position. Thus, the retractable peg 3138 may provide a similar function to the third peg 138 by: extends into the recess 1412/1414 when in the locked state and recedes from the recess when the mounting portion 3111 is transitioned to the unlocked state.

Referring again to fig. 31, the mounting portion 3111 may include inner pins 3132 extending through a back plate of the mounting portion 3111 behind the rotatable ring 3162. Figure 32 shows a diagrammatic side sectional view of the mounting portion and support arm taken along section line 32-32 in figure 31, which section line extends centrally through the inner peg 3132. In fig. 32, some components are shown simplified or omitted to provide improved clarity. As shown in fig. 32, a rotatable ring 3162 is positioned forward of the inner pin 3132. The inner pin 3132 extends from the mounting portion 3111 into the housing 3206 of the support arm 3104. Inner peg 3132 may contact locking member 3204 (i.e., a locking key or a biased locking key).

With the support arm 3104 in the lowered position, as shown in fig. 32, the locking member 3204 may be prevented from moving along the longitudinal axis L due to contact between the end portion 3210 of the housing 3206 and the block 3208, similar to the locking member 204 and block 208 of fig. 11. Accordingly, inner pin 3132 is also unable to translate along axis L relative to mounting portion 3111 due to its contact with locking member 204.

As shown in fig. 32, the rotatable ring 3162 may include a first portion of the rear surface 3165, a second portion of the rear surface 3167 having different longitudinal positions along the axis L, and an angled portion 3169 connecting the two portions of the rear surfaces 3165, 3167. With the support arm 3104 in the lowered position, as shown in fig. 32, the inner pin 3132 protrudes into the mounting portion 3111 to a longitudinal position forward of the second portion of the rear surface 3167. Accordingly, the rotatable ring 3162 is prevented from rotating in the direction D shown in fig. 32 due to the interference contact between the inner pin 3132 and the inclined portion 3169 of the rear surface. The direction D is also shown in fig. 31. Thus, in the lowered position of support arm 3104, rotatable ring 3162 is prevented from rotating and inner pin 3132 is prevented from retracting backwards along axis L. The mounting portion 3111 is thus not changeable to an unlocked configuration and is not removable from the display (e.g., 102).

Fig. 33 shows a partial front end view of the mounting portion of fig. 31 with the mounting portion in an unlocked condition. The latch (e.g., 3122) retracts. Inner peg 3132 is also shown hidden behind rotatable ring 3162. Figure 34 shows a side sectional view of the mounting portion and support arm taken at the location of section line 34-34 in figure 33. In fig. 34, the support arm 3104 has been rotated about pivot axis 3120 to the raised position. Thus, block 3208 has rotated away from end portion 3210 of locking member 3204. Releasing end portion 3210 allows locking member 3204 to translate along axis L relative to housing 3206. Thus, in the raised position, rotation of the angled portion 3169 of the rotatable ring 3162 into contact with the inner pin 3132 may drive the inner pin 3132 in an axially rearward direction, thereby driving the locking member 3204 rearward, as shown and indicated by the small axial arrow in fig. 34. Rotation of rotatable ring 3162 may allow unlocking of mounting portion 3111 and removal of the display from mounting portion 3111.

In some embodiments, when the mounting portion 3111 is unlocked, the display may be removed from a first orientation (e.g., landscape) and may be reattached in a second orientation (e.g., portrait). In some embodiments, unlocking the mounting portion 3111 allows the display to be rotated from one orientation to another orientation when positioned on the mounting portion 3111 (e.g., when the mounting portion 3111 is within the recess 1400). When the rotatable ring 3162 is reset to its default/biased locked configuration, the inner peg 3132 may be pushed forward again by the biasing device 3213 at the locking member 3204, thereby returning the rotatable ring 3162, inner peg 3132 and locking member 3204 to their state shown in fig. 32.

When the rotatable ring 3162 is rotated into the unlocked position, as shown in fig. 34, the mounting portion 3111 may be at an angle R about the pivot axis 3120₁Within a limited angular range of motion indicated. Thus, when the mounting portion 3111 is unlocked, the display may tilt about the pivot axis 3120 through the same range of angles of motion.

The mounting portion 3111 may include a second pin 3135 as shown in fig. 31 and 35. Fig. 35 illustrates a side cross-sectional view of the mounting portion 3111 and the support arm 3104 taken at the location of section line 35-35 in fig. 31, with the mounting portion inserted into the recess 1400 of the display housing 1420. Second peg 3135 may be biased in a longitudinally forward direction by locking member 3204 and biasing device 3213 in a manner similar to inner peg 3132. The second pin 3135 may extend into contact with the first rear surface 3137 of the recess of the display housing when the display is in the landscape orientation. When the display is in the portrait orientation, as shown in fig. 35, the second pin 3135 may contact a second rear surface 3141 of the display housing that is longitudinally closer to the pivot axis 3120 than the first rear surface 3137. The display housing may include an inclined surface 3141 to allow the second peg 3135 to be gradually pushed longitudinally rearward from the first rear surface 3137 as the display is rotated in direction D (see also fig. 31). The second pin 3135 may push the locking member 3204 rearward, as shown by the small arrows in the pin 3135 and locking member 3204 in fig. 35, so the locking member 3204 may prevent the support arm 3204 from moving to the lowered position due to interference with the block 3208. Thus, positioning the display in a portrait orientation prevents the support arm from being lowered, thereby preventing the display from contacting the support surface.

When the display is at the angle R₂In the portrait orientation within the defined range of angular motion, the display may tilt about pivot axis 3120. R is₂Can be greater than an angle R₁A defined range of motion. Thus, the angle R is such that when the display is changed from landscape to portrait (or vice versa)₁Corresponds to a possible reduced range of motion. This may help to prevent the corners of the display from tilting into contact with the support surface when the display is rotated from landscape to portrait (or vice versa). Thus, the range of motion over which the display is tilted while transitioning between orientations (i.e., while unlocked) may be limited to an angle R₁And the range of motion of the tilt of the display when locked in the portrait orientation may be limited to a larger angle R₂. In the locked portrait or landscape orientation, the display does not extend as close to the support surface as when transitioning between orientations. Angle R₁And R₂The difference in size of the spaces therebetween may be defined by the shape of the blocks 3208 or the shape of the locking members 3204 with which they contact each other.

Fig. 36 and 37 show side cross-sectional views of alternative embodiments of display housing 3620.

Figure 36 illustrates a side cross-sectional view of the mounting portion 3611 and the support arm 3604 taken along a section similar to section line 35-35 in figure 31. The mounting portion 3611 is inserted into a recess 3640 of another embodiment of the display housing 3620 in a first rotational orientation. In this case, the second pin 3635 is configured to extend into a pin-receiving recess 3700 in a rearward surface 3702 of the recess 3640 of the display housing 3620. In this state, the support arm 3604 is able to rotate freely about the pivot axis 3720 without the end portion 3710 of the locking member 3704 contacting the block 3708 of the housing of the support arm 3604. This first rotational orientation of display housing 3620 may correspond to a landscape orientation in which support arm 3604 may safely move the display up and down without contacting (e.g., bumping into) the support surface. The pin receiving recess 3700 can be configured to contact the side of the second pin 3635 in the event that a user attempts to rotate the display housing 3620, thereby limiting or preventing any possible rotation of the display housing 3620 relative to the support arm 3604. Accordingly, display housing 3620 may not rotate axially (e.g., about axis L) when attached to mounting portion 3611.

Figure 37 illustrates a side sectional view of the mounting portion 3611 and the support arm 3604 taken along a section similar to section line 35-35 in figure 31. The mounting portion 3611 is inserted into a recess 3640 of the display housing 3620 in a second rotational orientation. For example, the rotational orientation may correspond to a longitudinal orientation. To achieve this state, the display housing 3620 can be removed from the mounting portion 3611 when in a first orientation (e.g., landscape), can be rotated to a second orientation (e.g., portrait) when removed from the mounting portion 3611, and can then be reattached in the state shown in fig. 37. When the display housing 3620 is reattached, the second pin 3635 may contact the rearward surface 3702 in the recess 3640 and may be urged longitudinally rearward (e.g., along the axis L) as shown by the arrow in fig. 37. Similar to the state shown in fig. 35, rearward movement of second pin 3635 can push locking member 3704 rearward to a latched position, wherein rear end 3710 of locking member 3704 prevents support arm 3604 from rotating relative to display housing 3620 due to mechanical interference between rear end 3710 and block 3708.

When in the latched position, support arm 3604 may hold the display in a manner that prevents it from moving downward into contact with the support surface. In some embodiments, in such instances, display housing 3620 is prevented from rotating back to the first orientation (e.g., landscape) unless display housing 3620 is first removed from mounting portion 3611 and reattached in the configuration shown in fig. 36. Upon removal of display housing 3620 from the configuration shown in fig. 37, second pin 3635 may be biased forward to the position shown in fig. 36 by locking member 3704 and biasing device 3713, thereby removing interference between locking member 3704 and block 3708.

Such personal information data may include demographic data, location-based data, telephone numbers, email addresses, personal information data, and the like,

ID. A home address, data or records related to the user's health or fitness level (e.g., vital sign measurements, medication information, exercise information), a date of birth, or any other identifying or personal information.

The present disclosure recognizes that the use of such personal information data in the present technology may be useful to benefit the user. For example, the personal information data may be used to deliver target content that is of greater interest to the user. Thus, using such personal information data enables the user to have planned control over the delivered content. In addition, the present disclosure also contemplates other uses for which personal information data is beneficial to a user. For example, health and fitness data may be used to provide insight into the overall health condition of a user, or may be used as positive feedback for individuals using technology to pursue health goals.

The present disclosure contemplates that entities responsible for collecting, analyzing, disclosing, transmitting, storing, or otherwise using such personal information data will comply with established privacy policies and/or privacy practices. In particular, such entities should enforce and adhere to the use of privacy policies and practices that are recognized to meet or exceed industry or government requirements for maintaining privacy and security of personal information data. Such policies should be easily accessible to users and should be updated as data collection and/or usage changes. Personal information from the user should be collected for legitimate and legitimate uses by the entity and not shared or sold outside of these legitimate uses. Furthermore, such acquisition/sharing should be performed after receiving user informed consent. Furthermore, such entities should consider taking any necessary steps to defend and secure access to such personal information data, and to ensure that others who have access to the personal information data comply with their privacy policies and procedures. In addition, such entities may subject themselves to third party evaluations to prove compliance with widely accepted privacy policies and practices. In addition, policies and practices should be adjusted to the particular type of personal information data collected and/or accessed, and to applicable laws and standards including specific considerations of jurisdiction. For example, in the united states, the collection or acquisition of certain health data may be governed by federal and/or state laws, such as the health insurance association and accountability act (HIPAA); while other countries may have health data subject to other regulations and policies and should be treated accordingly. Therefore, different privacy practices should be maintained for different personal data types in each country.

Regardless of the foregoing, the present disclosure also contemplates embodiments in which a user selectively prevents use or access to personal information data. That is, the present disclosure contemplates that hardware elements and/or software elements may be provided to prevent or block access to such personal information data. For example, in the case of an ad delivery service, the present technology may be configured to allow a user to opt-in or opt-out of participating in the collection of personal information data at any time during or after registration service. In another example, the user may choose not to provide emotion-related data for the targeted content delivery service.
