Patent Description:
This document pertains generally, but not by way of limitation, to electronic display mounting systems.

Electronic displays, e.g., flat panel displays, can be supported by a mounting system to make them easily accessible by a user (e.g., to locate them over a desk surface). The mounting system can be freestanding (e.g., supported by a floor or by a desktop), coupled to a structure (e.g., a wall), or mobile (e.g., attached to a wheeled base). Mounting system can allow the user to easily alter the orientation of the electronic display (e.g., change a height, change and angle around a vertical axis, change an angle around a horizontal axis, or change a distance from the user) to accommodate users varying postures during the use of the electronic display. A number of mounting systems have already developed in the past.

The following drawings are illustrative of particular non-limiting example configurations of the present invention and therefore do not limit the scope of the invention. The drawings are not to scale and are intended for use in conjunction with the explanations in the following detailed description. Example configurations of the present invention will hereinafter be described in conjunction with the appended drawings. The drawings illustrate generally, by way of example, but not by way of limitation, various configurations discussed in the present document.

This disclosure is directed to a display mounting system to position one or more electronic displays relative to a structure, a desk, or a cart. More particularly, the display mounting system includes a height adjustable portion, and an articulating arm coupled to the height adjustable portion.

The following detailed description is exemplary in nature and is not intended to limit the scope, applicability, or embodiment of the invention in any way. Rather, the following description provides some practical illustrations for implementing exemplary configurations of the present invention. Examples of constructions, materials, dimensions, and manufacturing processes are provided for selected elements, and all other elements employ that which is known to those of ordinary skill in the field of the invention. Those skilled in the art will recognize that many of the noted examples have a variety of suitable alternatives.

An electronic display device can be used for presentation of information (e.g., images, text, or video) which can be transmitted electronically. Electronic display devices can include television sets, computer monitors, digital signage, and others. In some example configurations, the electronic display device can be wired or wirelessly connected to an information source (e.g., a computer, a computing network, a cloud-based software, and others). In other example configurations, the electronic display device can have a computer included inside the display housing.

The electronic display device can be positioned in a location where its content (e.g., images) can be easily visible to a viewer. For example, in some example configurations, the electronic display device can be located proximate to a workstation and it can be connected to a computer located proximate to the workstation. A user of the workstation can perform various computing functions (e.g., writing, drawing, calculating, and the like) while viewing images displayed on the electronic display device by the computer. In other example configurations, electronic display can be positioned over a wall, on a floor stand or on a wheeled base. A display mounting system can be used to couple the electronic display to a structure in these various configurations.

The display mounting system can provide both height adjustment and articulation (e.g., tilt, pan, side motion, and forward or backward motion) for the electronic display. The present inventors have recognized that it would be desirable to isolate these motions (e.g., height adjustment can be independent of forward or backward motion) to provide better control of the display mounting system functions. Existing solutions which include a counterbalanced height adjustable arm coupled to an extension arm can combine height adjustment (e.g., tilting the arm up/down) and articulation (e.g., panning the height adjustable arm relative to the extension arm) functions, and thus, they make it difficult to manipulate the orientation of the electronic display. This disclosure describes various techniques to isolate the height adjustment from the articulation of displays. These techniques will make it easy to manipulate the display mounting system and encourage users to adjust an orientation of one or more electronic display frequently throughout the day to match their varying postures and create more ergonomic work environment.

In other example configurations, the display mounting system <NUM> can include a riser assembly <NUM> and wall mounting plates <NUM> and <NUM> to couple it to a wall <NUM> (shown in <FIG>).

<FIG> is a perspective view of a display mounting system of <FIG>. The display mounting system <NUM> can be coupled to a structure (e.g., a desk surface <NUM>) to hold an electronic display device (for example to hold an electronic display device over a desk surface <NUM>). <FIG> is an exploded view of main sub-assemblies of the display mounting system <NUM>. The display mounting system <NUM> can include a base <NUM>, a riser assembly <NUM>, a truck assembly <NUM>, an arm assembly <NUM>, a cable management bracket assembly <NUM>, a cable management clip <NUM>, a tilt assembly <NUM>, and a display attachment bracket <NUM>.

A counterbalance mechanism (e.g., a counterbalance mechanism similar to the counterbalance mechanism <NUM> shown in <FIG>) can be included in the riser assembly <NUM>. The counterbalance mechanism <NUM> can be coupled to the riser assembly <NUM> and to the truck assembly <NUM>. The counterbalance mechanism <NUM> can lift at least a portion of the combined weight of all components (e.g., electronic display <NUM>, arm assembly <NUM>, and others) coupled to the truck assembly <NUM>. In some example configurations, the truck assembly <NUM> can provide height adjustment for the display attachment bracket <NUM> relative to the desk surface <NUM>.

The arm assembly <NUM> can be coupled to the truck assembly <NUM>. The arm assembly <NUM> can provide articulation for the display attachment bracket <NUM> relative to the riser assembly <NUM>. The position of the display attachment bracket <NUM> can be adjusted relative to the riser assembly <NUM> by moving the arm assembly <NUM>.

In some example configurations, a tilt assembly <NUM> can be coupled to the arm assembly <NUM>. In some example configurations, the tilt assembly <NUM> can further include a detachable display attachment bracket <NUM>. The display attachment bracket can be coupled to a display (e.g., the display <NUM> of <FIG>). The tilt assembly <NUM> can be configured to accept the display attachment bracket <NUM>. The tilt assembly <NUM> can adjust an angle of the display attachment bracket <NUM> relative to the riser assembly <NUM> around a horizontal first axis (not shown), and it can provide rotation of the display attachment bracket <NUM> relative to the desk surface <NUM> around a vertical second axis (not shown).

<FIG> is a perspective view of the display mounting system <NUM> of <FIG>. In some example configurations, a bow assembly <NUM>, and one or more tilt assemblies <NUM> can be coupled to the display mounting system <NUM> to hold one or more electronic displays. <FIG> is an exploded view of main sub-assemblies of the display mounting system <NUM> including a bow assembly <NUM>. The display mounting system <NUM> with the bow assembly <NUM> can provide height adjustment and articulation for the one or more displays coupled to the display mounting system <NUM>.

In some example configurations, a handle <NUM> can be coupled to the display mounting system <NUM> as illustrated in <FIG>. The handle <NUM> can help the user to easily manipulate the display mounting system <NUM> to change an orientation of the one or more electronic displays.

In some example configurations, the display mounting system <NUM> of <FIG> and <FIG> can include a cable management bracket assembly <NUM>, and one or more cable covers <NUM>. The one or more cable covers <NUM> can be coupled to the arm assembly <NUM> to route the cables between the one or more electronic displays (e.g., electronic display <NUM> of <FIG>) and the truck assembly <NUM>. The cable management bracket assembly <NUM> can be coupled to the truck assembly <NUM> and it can be coupled to the base <NUM>. The cable management bracket assembly <NUM> can route the cables between the truck assembly <NUM> and the base <NUM>. One or more electronic cables (e.g., power cable, video cable, or the like) can be routed through the one or more cable covers <NUM> and the cable management bracket assembly <NUM>. The one or more cable covers <NUM> and the cable management bracket assembly <NUM> can at least partially conceal the cables from outside view, and they can control the orientation of the one or more cables during height adjustment of the one or more displays.

<FIG> are side views of the display mounting system <NUM> of <FIG>. The arm assembly <NUM> is shown in extended orientation. A clamp bracket <NUM> can be coupled to the base <NUM>. The clamp bracket <NUM> can couple the display mounting system <NUM> to the desk surface <NUM>, (for example, it can fixedly attach the display mounting system <NUM> to an edge of the desk surface <NUM>). The truck assembly <NUM> can be configured to move along at least a portion of the riser assembly. In some example configurations, the truck assembly can transfer between an elevated position (as illustrated in <FIG>) and lowered position (as illustrated in <FIG>).

<FIG> are a perspective view and a top view of the riser assembly <NUM> together with the truck assembly <NUM>, respectively. The riser assembly <NUM> can include a support column <NUM>. The support column <NUM> can be coupled to the base <NUM>. In some example configurations, the support column <NUM> can extend upward from the base <NUM> in perpendicular direction to the lower surface of the base <NUM>. In other example configurations, the support column <NUM> can extend upwards from the lower surface of the base <NUM> in an angular orientation (e.g., in an obtuse angle).

The support column <NUM> can include a front face <NUM> and a rear face <NUM> opposite the front face <NUM>. The front face <NUM> and the rear face <NUM> of the support column <NUM> can be coupled to each other by a first side surface <NUM> and a second side surface <NUM> opposite the first side surface <NUM>. The front face <NUM>, the rear face <NUM>, the first side surface <NUM>, and the second side surface <NUM> of the support column <NUM> can form an elongated tubular structure. The support column <NUM> can be elongated in the axial direction <NUM> (shown in <FIG>). The first side surface <NUM> and the second side surface <NUM> of the support column <NUM> can form the first guide surface <NUM> and the second guide surface <NUM>, respectively.

The truck assembly <NUM> can be slidably engaged with the support column <NUM>. The truck assembly <NUM> can at least partially overlap with the support column <NUM>. Truck assembly can translate relative to the support column in the axial direction <NUM>. The truck assembly <NUM> can include one or more guiding components (e.g., glides, wheels, or the like). The one or more guiding components of the truck assembly <NUM> (e.g., the wheel assemblies <NUM> and <NUM> of <FIG>) can be in contact with the first <NUM> and the second <NUM> guide surfaces of the support column <NUM> to guide the truck assembly <NUM> during its translation relative to the support column <NUM>.

In some example configurations, the first guide surface <NUM> and the second guide surface <NUM> can be in a circular contour as illustrated in <FIG>. In other example configurations, the first <NUM> and the second <NUM> guide surfaces can be in other shapes including (but not limited to) oval, flat, and other shapes. Outside contour of the one or more guiding components of the truck assembly <NUM> (e.g., outside profile of the wheel <NUM> of <FIG>) can match the contour of the first <NUM> and the second <NUM> guide surfaces.

<FIG> is a front view of the riser and truck assemblies. In some example configurations, the front face <NUM> of the support column support column <NUM> can further include an opening (e.g., a slot <NUM>). The slot <NUM> can be an elongated opening formed in parallel to the axial direction <NUM>. The slot <NUM> can provide access to an internal space of the support column <NUM> where the counterbalance mechanism <NUM> (shown in <FIG>) can be located. A component of the truck assembly <NUM> (e.g., a hook, or the like) can penetrate through the slot <NUM> to couple with the counterbalance mechanism <NUM>.

<FIG> are front views of the riser assembly <NUM> in various configurations. The riser assembly <NUM> can include a support column <NUM>. The front face <NUM> of the support assembly <NUM> is removed in <FIG> to show the components located inside the support column <NUM>. A mounting bracket <NUM> can be coupled to the lower end of the support column <NUM>, and a top bracket <NUM> can be coupled to the upper end of the support bracket <NUM>. The span between the top bracket <NUM> and the mounting bracket <NUM> can define a length of the support bracket <NUM>. A counterbalance mechanism <NUM> can be included inside the support column <NUM> between the top bracket <NUM> and the mounting bracket <NUM>. The counterbalance mechanism <NUM> can be coupled to the support column <NUM> and to the truck assembly <NUM>. The counterbalance mechanism <NUM> can include one or more energy storage members (e.g., one or more extension springs <NUM>) and a wheel assembly <NUM>. The counterbalance mechanism <NUM> can further include an adjustment screw <NUM>, an adjustment bracket <NUM>, and a connecting bracket <NUM>. The adjustment bracket <NUM> and the connecting bracket <NUM> can be adapted to translate in the axial direction <NUM>. The one or more springs <NUM> can be coupled to the adjustment bracket <NUM> on one end and coupled to the connecting bracket <NUM> on the other end. Additional information regarding this conversion can be found in commonly assigned <CIT>et al. , which is incorporated by reference in its entirety.

In some example configurations, the adjustment screw <NUM> can be coupled to the top bracket <NUM>. The adjustment screw <NUM> can include a head (not shown) and a threaded shaft. The threaded shaft of the adjustment screw <NUM> can extend from the head along an axial direction (not shown) of the adjustment screw <NUM>. The head of the adjustment screw <NUM> can be supported by the top bracket <NUM>. The axial direction of the adjustment screw <NUM> can be parallel to the axial direction <NUM> of the support column <NUM>.

The adjustment bracket <NUM> can have a threaded hole. The adjustment screw <NUM> can be threadingly engaged with the adjustment bracket <NUM> through the threaded hole of the adjustment bracket <NUM>. The adjustment bracket <NUM> can be guided by the support column <NUM> to prevent it from rotating relative to the support column <NUM> as the adjustment screw <NUM> rotates around its axis. The adjustment bracket <NUM> can be configured to translate along the axial direction of the adjustment screw <NUM>. The adjustment screw <NUM> can be used in combination with the adjustment bracket <NUM> to adjust a tension of the one or more springs <NUM>.

A low-tension configuration of the one or more springs <NUM> is illustrated in <FIG>. In the low-tension orientation, the adjustment bracket <NUM> can be located at a first distance 251A from the top bracket <NUM>. A high-tension configuration of the one or more springs <NUM> is illustrated in <FIG>. The adjustment bracket <NUM> can be translated closer to the top bracket in high-tension orientation. In the high-tension orientation, the adjustment bracket <NUM> can be located at a second distance 251B from the top bracket <NUM> where the second distance 251B is smaller than the first distance 251A. As the tension is increased on the one or more springs <NUM> (e.g., configuration shown in <FIG>), the counterbalance mechanism <NUM> can lift a larger weight coupled to the wheel assembly <NUM>.

<FIG> is a close-up view of the upper portion of the riser <NUM> and the truck <NUM> assemblies. In some example configurations, a weight adjustment indicator strip <NUM> can be coupled to the adjustment bracket <NUM>. The indicator strip <NUM> can have a first edge <NUM> and a second edge <NUM> opposite the first edge <NUM>. The indicator strip <NUM> can further include a third edge <NUM> and a fourth edge <NUM> opposite the third edge <NUM>. The first edge <NUM>, the second edge <NUM>, the third edge <NUM>, and the fourth edge <NUM> can form a planar surface with a width between the first edge <NUM> and the second edge <NUM>, and a length between the third edge <NUM> and the fourth edge <NUM>. The indicator strip <NUM> can have an elongated shape where the length is substantially larger than the width. The indicator strip <NUM> can be coupled to the adjustment bracket <NUM> proximate its third edge <NUM>. The indicator strip <NUM> can be adapted to move with the adjustment bracket <NUM> during the adjustment of the tension of one or more springs <NUM>.

A lift force indicator line <NUM> can be formed on the planar surface of the indicator strip <NUM> as illustrated in <FIG> according to an example configuration of the current disclosure. The indicator line <NUM> can be at an angle relative to the first side <NUM> and the second side <NUM> of the indicator strip <NUM>. The indicator line <NUM> can be inclined from the first side <NUM> towards the second side <NUM> of the indicator strip <NUM> so that a distance measured between the first side <NUM> and the indicator line <NUM> in a direction that is perpendicular to the first side <NUM> can be larger if the measurement location is further away from the third side <NUM> of the indicator strip <NUM>.

In an example configurations, a window <NUM> can be formed on the front face <NUM> of the support column <NUM> as illustrated in <FIG>. The window <NUM> can be configured to at least partially overlap with the indicator strip <NUM>. The planar surface of the indicator strip <NUM> (e.g., the surface on which the indicator line <NUM> is formed) can face towards the front face <NUM> of the support column <NUM> such that the indicator line <NUM> can be at least partially visible through the window <NUM>. The location of the window <NUM> can be stationary relative to the support column <NUM>. The adjustment bracket <NUM> and the indicator strip <NUM> can move relative to the support column <NUM> during the adjustment of the tension of one or more springs <NUM>.

Some example configurations of the indicator line <NUM> as it can be visible through the window <NUM> are illustrated in <FIG>. The orientation of the indicator line <NUM> visible through the window <NUM> can be adapted to indicate a relative magnitude (e.g., low, high) of the lift force generated by the counterbalance mechanism <NUM>.

In some example configurations when the tension is lowered on the one or more springs <NUM> (e.g., the adjustment bracket <NUM> is moved away from the upper end of the support column <NUM> and towards the window <NUM> as illustrated in <FIG>), a lift force generated by the counterbalance mechanism <NUM> can be low. In this configuration, the indicator strip <NUM> can also move with the adjustment bracket <NUM> away from the upper end of the support column <NUM>, and a portion of the indicator line <NUM> proximate the third side <NUM> of the indicator strip <NUM> (e.g., the indicator line <NUM> can be close to the first side <NUM>) can be visible through the window <NUM> as illustrated in <FIG>.

In other example configurations, when the tension is increased on the one or more springs <NUM> (e.g., the adjustment bracket <NUM> is moved closer to the upper end of the support column <NUM> and away from the window <NUM> as illustrated in <FIG>), a lift force generated by the counterbalance mechanism <NUM> can be high. In this configuration, the indicator strip <NUM> can also move with the adjustment bracket <NUM> towards the upper end of the support column <NUM>, and a portion of the indicator line <NUM> proximate the fourth side <NUM> of the indicator strip <NUM> (e.g., the indicator line <NUM> can be farther away from to the first side <NUM>) can be visible through the window <NUM> as illustrated in <FIG>.

In some example configurations, a magnitude of the lift force can be indicated by one or more numbers (e.g., numbers from <NUM> to <NUM>) instead of an indicator line. The one or more numbers can be printed on the indicator strip <NUM>, and depending on the spring adjustment, a number can be visible through the window <NUM>. The number visible through the window <NUM> can be adapted to correspond to a level of adjustment (e.g., <NUM> being a lower lift force than <NUM>).

In other configurations, a movement of the adjustment bracket <NUM> (and thus, a movement of the indicator strip <NUM>) can be adapted to correlate to an actual lift force provided by the counterbalance mechanism <NUM>. The movement of the adjustment bracket <NUM> can be an indication of the spring tension. The spring tension can be converted to a spring force using the spring parameters (e.g., spring stiffness, and initial tension). The calculated spring force can be converted to a lift force using the known cam and wheel geometry. The calculated lift force corresponding to a movement of the adjustment bracket <NUM> can be printed on the indicator strip <NUM>, and it can be visible through the window <NUM>.

The wheel assembly <NUM> can include a wheel <NUM> and a cam <NUM>. In some example configurations, the wheel <NUM> and the cam <NUM> can be formed as integral parts of the wheel assembly <NUM>. In other configurations, the wheel <NUM> and the cam <NUM> can be formed separately and coupled to each other to form the wheel assembly <NUM>. An axle <NUM> can be coupled to the mounting bracket <NUM>. The wheel assembly <NUM> can be coupled to the mounting bracket <NUM> through the axle <NUM>. The wheel assembly <NUM> can be configured to rotate around the axle <NUM>.

In an example configuration, the counterbalance mechanism <NUM> can include a tensile member <NUM> (e.g., a rope, wire, cord, or the like). One end of the rope <NUM> can be coupled to the connecting bracket <NUM>. The rope <NUM> can engage with a portion of the wheel assembly <NUM> and extend towards an idler pulley <NUM> coupled to the top bracket <NUM> proximate the upper end of the support column <NUM>. The rope <NUM> can further wrap around the idler pulley <NUM> to change direction and extend towards the lower end of the support column <NUM>. A loop <NUM> can be formed at the other end of the rope <NUM>. The loop <NUM> can be coupled to the truck assembly <NUM>.

In another example configuration, the counterbalance mechanism <NUM> can include two or more tensile members as illustrated in <FIG>. For instance, a first tensile member <NUM> can be coupled between the cam <NUM> and the connecting bracket <NUM>. A second tensile member <NUM> can have a loop <NUM> on one end. The loop <NUM> can be coupled to the truck assembly <NUM>. The second tensile member <NUM> can be routed around the idler pulley <NUM> and the other end of the second tensile member <NUM> can be coupled to the wheel assembly <NUM>.

<FIG> illustrates an orientation of the truck assembly <NUM> located proximate the upper end of the height adjustment range (e.g., the truck assembly <NUM> is proximate the upper end of the support column <NUM>). In this orientation, the first tensile member <NUM> can be coupled between the connecting bracket <NUM> and the cam <NUM>, and the second tensile member <NUM> can be coupled between the wheel <NUM> and the truck assembly <NUM> (e.g., the loop <NUM> located at the end of the second tensile member <NUM> can engage with a component, e.g., hook, of the truck assembly <NUM>). In this orientation, the second tensile member <NUM> can be wrapped around the wheel <NUM>.

<FIG> illustrates an orientation of the truck assembly <NUM> located proximate the lower end of the height adjustment range (e.g., the truck assembly <NUM> is proximate the lower end of the support column <NUM>). As the truck assembly <NUM> translates towards the lower end of the height adjustment range, the loop <NUM> translates with the truck assembly <NUM>, and thus, increasing the distance between the idler pulley <NUM> and the loop <NUM>. Increased length of the second tensile member <NUM> between the idler pulley <NUM> and the loop <NUM> can be provided by the rotation (e.g., in clockwise direction) of the wheel assembly <NUM> (e.g., by unwrapping a portion of the second tensile member <NUM> that was wrapped around the wheel <NUM>). The cam <NUM> can also rotate with the wheel assembly <NUM>, therefore, a portion of the first tensile member <NUM> can be wrapped around the cam <NUM>. Wrapping a portion of the first tensile member <NUM> can pull the connecting bracket <NUM> towards the wheel assembly <NUM> by further stretching the one or more springs <NUM> as illustrated in <FIG>. Further stretching the springs <NUM> can increase the spring force. However, increasing spring force can be adapted to be converted to a constant lift force applied to the truck assembly <NUM> via the loop <NUM> by varying the radius of the cam <NUM> continuously at the contact point between the cam <NUM> and the first tensile member <NUM>.

Referring again to <FIG>, the one or more springs <NUM>, the rope <NUM>, and the wheel assembly <NUM> can cooperate to help counterbalance a force applied to the truck assembly <NUM>. Counterbalancing the force applied to the truck assembly <NUM> can help maintain the amount of force required to translate the truck assembly <NUM> with respect to the support column <NUM>. Stated another way, the counterbalance mechanism <NUM> can be adapted to support the truck assembly <NUM> such that the amount of force necessary to translate the truck assembly <NUM> with respect to the support column <NUM> remains substantially constant, despite increasing force created by the springs <NUM> during translation. Additionally, the counterbalance mechanism <NUM> can help maintain a position of the truck assembly <NUM> with respect to the support column <NUM>, such as by providing a lift force equivalent to the combined weight of the truck assembly <NUM> and all the components coupled to it, including (but not limited to) one or more displays (shown in <FIG>).

In an example configuration, the truck assembly <NUM> can be operationally coupled to the counterbalance mechanism <NUM> and coupled to the electronic display <NUM> (shown in <FIG>). The counterbalance mechanism <NUM> can help maintain the position (e.g., height) of the truck assembly <NUM> (and thereby the display <NUM>) with respect to the desk surface <NUM>. Moreover, if the user desires to change the position (e.g., raise or lower) of the display <NUM>, the counterbalance mechanism <NUM> can help maintain the amount of force necessary to change the position of the truck assembly <NUM> (and thereby the display <NUM>) such that the amount of force necessary to change the position of the truck assembly <NUM> with respect to the desk surface <NUM> can be substantially constant.

<FIG> are perspective views of the base <NUM> according to an example configuration of the current disclosure. The base <NUM> can include a flat bottom surface <NUM>. The bottom surface <NUM> can be adapted to be placed on a desk surface <NUM>. The base <NUM> can include a front end <NUM> and a rear end <NUM>. The front end <NUM> and the rear end <NUM> of the base <NUM> can be connected by right-side wall <NUM> and the left-side wall <NUM>. In some example configurations, the base <NUM> can have a hollow portion <NUM> between the front end <NUM>, the rear end <NUM>, the right-side wall <NUM>, and the left-side wall <NUM>. One or more features can be formed in and around the hollow portion <NUM> of the base <NUM> to secure the cable management components (e.g., cable management bracket assembly <NUM> and cable management clip <NUM> of the display mounting system <NUM> of <FIG>) as it will be apparent in the following sections of this disclosure.

In some example configurations, a first clip <NUM> can be formed proximate the rear end <NUM>, and a second clip <NUM> can be formed proximate the front end <NUM> of the base <NUM>. One or more recesses <NUM> can be formed on the left-side wall <NUM> of the base <NUM>. The one or more recesses <NUM> can initiate from the bottom surface <NUM> of the base <NUM> and extend upwards into the left-side wall <NUM>. The one or more recesses <NUM> can merge with the hollow portion <NUM> of the base <NUM>. In some configurations, the one or more recesses <NUM> can also be formed on the right-side wall <NUM> of the base <NUM>. A shallow cavity <NUM> can be formed proximate the rear end <NUM> of the base <NUM>. One or more apertures <NUM> can be formed inside the shallow cavity <NUM>. The shallow cavity <NUM> can be adapted to receive the lower end of the riser assembly <NUM> (e.g., the mounting bracket <NUM> of <FIG> can be located inside the shallow cavity <NUM>). One or more screws (not shown) can be inserted through the one or more apertures <NUM> to engage with the mounting bracket <NUM> to secure the mounting bracket <NUM> to the base <NUM>.

A clamp screw housing <NUM> can be located proximate the rear end of the base <NUM>, and it can extend upwards from the base <NUM>. In some example configurations, the clamp screw housing <NUM> can be formed as an integral part of the base <NUM>. In other example configurations, the clamp screw housing <NUM> can be formed as a stand-alone component and coupled to the base <NUM> during the assembly process.
