DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[24] The following detailed description is exemplary in nature and is not intended to limit the scope, applicability, or configuration of the invention in any way. Rather, the following description provides some practical illustrations for implementing exemplary embodiments 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.

[25] Embodiments described herein can be useful for lockably mounting and

positioning electronic equipment on a support system. Figures 1 and 2 are perspective views of embodiments of a support system 10 for electronic equipment (e.g., a monitor) and Figure 3 is a front view of the support system shown in Figure 2 holding electronic equipment 20. As shown, in some embodiments the support system 10 can be configured for mounting the electronic equipment 20 to a support surface 30 (e.g., a desk). The support system 10 can include a mounting bracket 40 (e.g., a VESA bracket) adapted to receive the electronic equipment 20. In some embodiments, the support system 10 can include a base 50, a riser 60, a support 70 and a locking mechanism 100.

[26] The support system can assume any configuration useful for positioning

electronic equipment. In some embodiments, the base 50 can include a clamp 52 adapted to attach the support system 10 to an edge of a support surface 30. In other embodiments, the base 50 may include a grommet mount adapted to engage with a grommet hole on a support surface. Such embodiments can be useful for securing electronic equipment coupled to the support system to a rigid work surface.

[27] Referring to Figures 1 and 2, the support 70 can be operatively coupled to the riser 60. In some embodiments, the support 70 can slidingly engage with the riser 60, and can be rotatably engaged about the riser 60. The support 70 defines an aperture 92 sized to receive the riser 60. In some embodiments, the support 70 includes one or more arms, such as a first arm 94. The first arm 94 can be adapted to engage with the mounting bracket 40 or additional arms and support the electronic equipment 20. As shown in Figures 2 and 3, the support 70 can include a second arm 96 with joints 98 articulating with respect to the riser 60. The joints 98 are adapted to move and reposition electronic equipment 20 supported by the second arm 96.

[28] As shown in Figures 3 and 4, the riser 60 can extend vertically from the base 50 and include a cavity 64 defined by an interior surface 82 of the riser 60 (e.g., the riser 60 can be a hollow cylinder). A leading edge 84 of the riser 60 can be generally perpendicular to a longitudinal axis 86 of the riser 60. For purposes of illustration, hidden elements have been schematically projected over the side views of Figures 3 and 4. The leading edge 84 can define a perimeter of the interior surface 82 forming the cavity 64 of the riser 60. In the illustrated embodiments, the riser 60 is cylindrical in shape, leading to the leading edge defining the circumference of the cylindrical riser 60. [29] With continued reference to Figures 3 and 4, the locking mechanism 100 can restrict the removal of the support 70 from the riser 60. In some embodiments, the locking mechanism 100 can be positioned at the distal end 62 of the riser 60. In certain embodiments, the locking mechanism 100 can be received by the cavity 64 in the riser 60.

[30] Figures 5 and 6 illustrate respectively, an exploded perspective view and an exploded side view of the locking mechanism 100 according to some embodiments. The locking mechanism 100 can include a first block 110, a second block 120 and a fastener 130. The first block 1 10 can include a first aperture 1 12, a first inclined surface 1 14, and a distal surface 1 16 opposite the first inclined surface 1 14. The distal surface 1 16 can include a lip 1 18. The second block 120 can include a second aperture 122 in axial alignment with the first aperture 112 and a second inclined surface 124 in apposition to the first inclined surface 114.

[31] In some embodiments, the first aperture 1 12 can extend through the distal surface 1 16 and the first inclined surface 1 14. The second aperture 122 can extend through the second inclined surface 124. The fastener 130 can extend through the first and second apertures 1 12, 122. The fastener can include a washer 132 seated on the distal surface 1 16 of the first block 1 10. In some embodiments, a cap 140 coupled to the distal surface or the riser can be provided to cover the first block 110. In such embodiments, the cap 140 can also cover a head 134 of the fastener 130 seated in the first aperture 112 of the first block 110.

[32] As best seen in Figure 6, the first block 1 10 includes a distal surface 1 16

opposite the first inclined surface 114. The distal surface 1 16 includes a lip 118 adapted to prevent the support from disengaging with the riser 60. Referring back to Figure 4, the lip 1 18 can extend beyond a perimeter of the riser 60. The lip 1 18 can be in apposition to the leading edge 84 of the riser 60. In some embodiments, the lip 1 18 of the locking mechanism 100 can be larger than the aperture defined by the support.

[33] Figures 7A-7 D and 8A-8 D illustrate various views of the first block 110 and the second block 120, respectively. From Figures 7A and 8A, it can be seen that certain embodiments of the first block 1 10 and the second block 120 have the shape of a truncated cylinder (e.g., a cylindrical wedge). As shown, a plane of truncation can be non-parallel with a longitudinal axis of the cylinder. The shape of the first block 1 10 and the second block 120 are such that the first block 1 10 and second block 120 can wedge against each other if either of the first and second blocks 110, 120 moves relative to each other. As seen in Figures 7B and 8B, the first block 110 and the second block 120 can each have a circular profile when viewed from a top. As seen in Figures 7C and 8C, the first block 1 10 and the second block 120 each have a triangular profile when viewed from a side.

[34] The fastener 130 includes a threaded portion (not shown) adapted to

threadingly engage with a locking nut 136. The fastener 130 can include a bolt, nut and washer assembly. As best seen in Figures 8A and 8D, the second block 120 can include a recess 126 adapted to receive the locking nut 136. The recess 126 can be positioned at a proximal surface 128 of the second block 120. The first aperture 1 12 can include an elongate portion, such as a rounded rectangular shape (e.g., a rounded slot) such that the first block 110 can move laterally relative to the fastener 130 as it is tightened. The second aperture 122 can have a circular shape.

[35] In a non-limiting exemplary embodiment, the fastener 130 can be a bolt with right-handed threads. In such embodiments, a clockwise rotation can move the fastener 130 in a substantially downward direction and apply a force on the first and second blocks 1 10, 120. The force imparted by tightening the fastener 130 can cause the first and second inclined surfaces 1 14, 124 to wedge against each other, and consequently moving the first block 1 10 and second block 120 in opposing directions. The directions of movement of the first block 1 10 and the second block 120 "xl" and "x2" are illustrated in Figures 9A and 9B. Tightening the fastener 130 moves the first block 1 10 in a first direction "xl", and the second block 120 in a second direction "x2". The second direction "x2" can be opposite the first direction "xl". The fastener 130 can be fixedly coupled to the second block 120 by the locking nut 136 positioned in the recess 126 (best seen in Figure 8D), such that when the second block 120 moves in a second direction "x2", the fastener 130 moves by a first distance along the second direction "x2".

[36] Referring back to Figures 9A and 9B, the first inclined surface 1 14 of the first block 1 10 can be adapted to slide with respect to the second inclined surface 124 when the fastener 130 is tightened to increase a force between the first and second inclined surfaces 114, 124. The first inclined surface 1 14 slides in a direction "si" opposing the direction of sliding "s2" of the second inclined surface 124. The first and second blocks 1 10, 120 can be configured to move when the fastener 130 is tightened, such that a portion 150 of the first inclined surface 1 14 extends laterally beyond the second block 120 and/or a portion 160 of the second inclined surface 124 extends laterally beyond the first block 1 10. In some embodiments, the portions that extend laterally beyond the first block 110 and second block 120 can each define a gap. In the illustrated embodiment, the truncated cylindrical shapes of the first and second blocks 1 10, 120 lead to gaps 170, 180 that are shaped as truncated cylinders. As shown, when viewed from a side, the gaps 170, 180 are triangular in shape.

[37] With continued reference to Figures 9A and 9B, turning or tightening the fastener 130 imparts a force to the first and second blocks 1 10, 120. The movements of the first and second blocks 110, 120 can continue until outer surfaces 192 and 194 of the first and second blocks 1 10, 120 abut and are positioned snugly against the interior surface 82 the of riser 60. Once positioned against the interior surface 82 of the riser 60, the lip 118 of the distal surface 116 will be in apposition to the leading edge 86 of the riser and extend beyond the perimeter 84 of the riser 60. The lip 118 can prevent the removal of the support and the electronic equipment 20 coupled to the support from the riser after the locking mechanism 100 is secured against the interior surface 82 of the riser 60.

[38] Embodiments described elsewhere herein can be useful for supporting and locking electronic equipment to a support surface (e.g., desk). A method of locking a support to a riser can include one or more of the following steps: (i) providing a locking mechanism such as those described elsewhere herein, (ii) aligning the second block with respect to the first block such that the second aperture is axially in-line with the first aperture, and the second inclined surface is in apposition to the first inclined surface, and (iii) tightening the fastener so that the first block slides with respect to the second inclined surface to increase a force between the first and second inclined surfaces, wherein a portion of the first inclined surface extends laterally beyond the second block and a portion of the second inclined surface extends laterally beyond the first block.

[39] Thus, embodiments of the invention are disclosed. Although the present invention has been described in considerable detail with reference to certain disclosed embodiments, the disclosed embodiments are presented for purposes of illustration and not limitation and other embodiments of the invention are possible. One skilled in the art will appreciate that various changes, adaptations, and modifications may be made without departing from the spirit of the invention.
