[0002] [Citation of Related Applications] This application claims priority to U.S. Provisional Patent Application No. 63 / 409,113, filed September 22, 2022, which is incorporated by reference in its entirety. [Background technology]

[0003] Electronic devices, such as laptops, tablets, or mobile phones, are often used in work environments. Typically, the electronic devices are placed on a support structure. It is often desirable for a user to adjust the height or location of the electronic device relative to the desktop to get a good view of the electronic device. However, many support structures for electronic devices are difficult to adjust and require significant effort by the user to adjust the height or location of the electronic device. Furthermore, many support structures do not allow for the range of motion necessary for a complete ergonomic solution and take up a large amount of space on the desktop. Summary of the Invention

[0004] In one aspect, the present application provides an adjustable support for an electronic device, the adjustable support comprising: a platform configured to support the electronic device; a post extending between a first end and a second end; and a linkage assembly that movably supports the electronic device on the post, the linkage assembly including a plurality of movable linkages configured to adjust the tilt of the platform to a plurality of different tilt angles.

[0005] In another aspect, the present application provides an adjustable support for an electronic device, the adjustable support having a platform configured to support the electronic device, a post extending between a first end and a second end, and a linkage assembly that movably supports the electronic device on the post, the linkage assembly being slidably coupled to the post to adjust the height of the platform, the linkage assembly including a plurality of movable linkages configured to adjust the tilt of the platform to a plurality of different tilt angles.

[0006] In another aspect, the present application provides an adjustable support for an electronic device, the adjustable support comprising: a platform configured to support the electronic device; a post extending between a first end and a second end; and a linkage assembly movably supporting the electronic device on the post, the linkage assembly being slidable along a longitudinal axis of the post to adjust the height of the platform, the linkage assembly including a friction grip that allows the linkage assembly to move freely in an upward direction and can prevent the linkage assembly from moving in a downward direction until an applied force overcomes the friction force provided by the friction grip.

[0009] Before describing any of the embodiments of the present invention in detail, it should be understood that the present invention is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the following drawings. The present invention is capable of other embodiments and of being practiced or carried out in various ways. It should be understood that the description of particular embodiments does not limit the disclosure, as the disclosure includes all modifications, equivalents, and alternatives falling within the spirit and scope of the disclosure. It should also be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting the invention.

[0010] FIG. 1 illustrates an adjustable support 10 configured to support an electronic device, such as a computer, laptop, tablet, mobile phone, or other device. The adjustable support 10 is coupled to a base 12. In some embodiments, the base 12 may include a horizontal base, such as a desktop or tabletop. In other embodiments, the base 12 may be a separate platform that can be supported on a desktop, tabletop, or other surface. In other embodiments, the base may include a vertical base, such as a wall or post. Additionally, in other embodiments, the base may be a privacy booth or cubicle that includes multiple walls defining an interior work base area. The adjustable support 10 provides a complete ergonomic solution for users and minimizes the space it occupies on a desktop.

[0011] 1 and 2, adjustable support 10 includes post 14, platform 18 for supporting electronic equipment, and linkage assembly 26 for adjusting the height and / or orientation of the platform. Post 14 is supported by base 12, and linkage assembly 26 movably engages post 14. Platform 18 is supported by linkage assembly 26 and can move relative to post 14. Linkage assembly 26 allows platform 18 to move to different heights (i.e., vertically) and different orientations (e.g., different tilt angles), as shown in FIGS. 12A-12C. In some embodiments, platform 18 may optionally include a platter ledge 22 to provide additional support for the electronic equipment and prevent the electronic equipment from sliding off platform 18.

[0012] While an exemplary embodiment of the adjustable support 10 is described, some aspects of the post 14, platform 18, and linkage assembly are optional features. The post 14 is formed as a hollow tube that can house other components of the adjustable support 10. In some embodiments, the post 14 is formed as a cylindrical or rectangular tube. The illustrated post 14 includes a post housing 30 having a post top plate 34, a post first housing portion 38, and a post second housing portion 42. The post top plate 34, the post first housing portion 38, and the post second housing portion 42 together define a post cavity 44. The post 14 has a first end 46 and a second end 50 opposite the first end 46. A longitudinal axis 54 extends through the center of the post 14 between the first end 46 and the second end 50. The post 14 has a length defined along a longitudinal axis 54 between a first end 46 and a second end 50 .

[0013] As shown in FIGS. 2 and 3 , the post 14 has a post slot 58. In the illustrated embodiment, the post first housing portion 38 and the post second housing portion 42 define the post slot 58. In other embodiments, the post 14 may be formed by a single housing having the slot 58. As described in more detail below, the linkage assembly 26 extends through the post slot 58 to a distal location away from the post 14 ( FIGS. 3 and 5 ). In some embodiments, the post 14 may optionally include a printed circuit board (PCB) with a universal serial bus (USB) port or power hub 62 to provide connectivity or power to electronic devices ( FIG. 6 ). In some embodiments, the post 14 may optionally include a hole 66 in the post first housing portion 38. In some embodiments, the hole 66 provides a location for a USB or power cable to extend from the post housing 30 and connect to electronic devices (not shown). In these embodiments, the USB or power cable may connect to the USB or power hub 62 (not shown).

[0014] In some embodiments, the post 14 may optionally include a rack 70 located therein, particularly in the post cavity 44 ( FIG. 7 ). The rack 70 includes a plurality of teeth that may be formed directly in one of the housing portions 38, 42. Alternatively, the rack 70 may be a separate component positioned within the post cavity 44. As described in more detail below, the rack 70 may be used to help create smooth and consistent movement of the linkage assembly 26. Additionally or alternatively, the rack 70 may optionally be used to help maintain or limit movement of the linkage assembly 26.

[0015] Continuing to refer to FIG. 7 , the post 14 may optionally further include one or more tracks 74. The tracks 74 are disposed within the post 14, specifically within the post cavity 44. The tracks 74 are formed within the post 14 and configured as channels extending along the longitudinal axis 54. The tracks 74 may extend along most or only a portion of the length of the post 14, depending on the desired range of motion of the linkage assembly 26. In the illustrated embodiment, the post 14 includes two tracks 74. In other embodiments, the post 14 includes one or more (e.g., one, two, three, or four) tracks 74. The linkage assembly 26 includes a rail 136 that engages the tracks 74 to guide movement of the linkage assembly 26 along the post 14 between the first end 46 and the second end 50. The tracks 74 and rails 136 may be used to guide the movement of the linkage assembly 26 in a linear direction along the longitudinal axis 54 and to help prevent "pinching" or "sticking" of the linkage assembly 26 as it slides along the post 14. In particular, because the linkage assembly 26 is cantilevered from the post 14, the linkage assembly 26 may tilt forward and create friction (i.e., sticking or pinching) that reduces the smoothness of the sliding movement of the linkage assembly 26. Therefore, some embodiments of the adjustable support 10 may optionally include tracks 74 and rails 136 to help reduce some of the friction and stress created by the cantilevered structure. It should also be noted that in some embodiments, the rail 136 may be positioned within the post 14 and the track 74 may also be positioned on the linkage assembly 26 .

[0016] 1 and 2, the platform 18 is configured to support an electronic device above a surface. The platform 18 may have a square, rectangular, or other suitable shape for supporting the electronic device. In some embodiments, the platform 18 may optionally include a ridge or gripping surface for maintaining the electronic device on the platform 18. The platform 18 further includes a platform ledge 22 extending from the platform 18. The platform ledge 22 may also be referred to as a lip. The platform ledge 22 is configured to prevent the electronic device from sliding off the platform. In the illustrated embodiment, the platform ledge 22 may extend at an angle of approximately 90° relative to the platform 18. In other embodiments, the platform ledge 22 may extend at an angle relative to the platform 18.

[0017] The platform 18 is supported on the post 14 by a linkage assembly 26. Specifically, the linkage assembly 26 helps to allow movement of the platform 18 to different heights along the longitudinal axis 54. This is accomplished by moving the entire linkage assembly 26, and thus the platform 18, up and down relative to the post 14. The linkage assembly 26 also allows for pivotal movement of the platform 18 in different orientations. This is achieved by moving various linkages of the linkage assembly 26 to redirect the angle of the platform 18. In the illustrated embodiment, the linkage assembly 26 is a four-bar linkage assembly, which is comprised of four links connected together in a closed loop. The linkage assembly 26 is configured to tilt the platform 18 to different angles while maintaining a consistent center of gravity 184. As shown in FIGS. 13A-13D , the center of gravity 184 (i.e., the center of gravity of the platform 18 and electronics 180) is maintained along a generally straight, horizontal path (i.e., center of gravity line 188). In some embodiments, the center of gravity 184 (i.e., the center of gravity of the platform 18 and electronics 180) may be maintained approximately ±5 mm from the straight, horizontal path (e.g., center of gravity line 188). By maintaining the center of gravity 184 along a generally straight, horizontal path, the linkage assembly 26 can balance the platform 18 at various tilt angles without requiring a rigid locking assembly. However, in some embodiments, the linkage assembly 26 can be assisted with additional or optional locking features.

[0018] 7 and 8 illustrate an exemplary embodiment of the linkage assembly 26. The following description is illustrative, and certain aspects and features of the linkage may differ in other embodiments. For example, the dimensions, shape, and coupling mechanism may vary from embodiment to embodiment. It should be understood that there are many different ways to configure the four-bar linkage assembly 26 that can tilt the platform 18 as described. The illustrated embodiment of the linkage assembly 26 is a four-bar linkage that includes a first arm 78, a second arm 80, a mount or mounting plate 84, and a carrier 92. The mount plate 84 is directly coupled to the platform 18. The carrier 92 can slide vertically along the longitudinal axis 54 while coupled to the post 14. In the four-bar linkage assembly 26, the carrier 92 is considered a "fixed link" in that it cannot rotate. The first arm 78 and the second arm 80 extend between the carrier 92 and the mount plate 84 and are configured to move the mount plate 84 (and platform 18) relative to the carrier 92 and the post 14. Specifically, movement of the first arm 78 and the second arm 80 adjusts the tilt angle of the platform 18. The first and second arms 78, 80 can be coupled to the mount plate 84 and the carrier 92 in a variety of ways. The first and second arms 78, 80 can also take on a variety of shapes.

[0019] 8 and 11 , the first arm 78 has a first end 96 and a second end 100 opposite the first end 96 ( FIG. 11 ). In some embodiments, the first arm 78 may be an L-shaped arm. The first end 96 of the first arm 78 is rotatably coupled to the carrier 92, and the second end 100 of the first arm 78 is rotatably coupled to the mount plate 84. In some embodiments, the first arm 78 is secured to the carrier 92 by a pin 104 and to the mount plate 84 by a peg 108. As shown in FIG. 11 , the first arm 78 has a plurality of first arm teeth 110. The plurality of first arm teeth 110 extend from the first end 96 of the first arm 78. The plurality of first arm teeth 110 engage with an indexing key 144 provided on the carrier 92, as described in detail below.

[0020] The illustrated embodiment of the second arm 80 may include a Y-shaped arm having a first limb 122 and a second limb 124. The first limb 122 extends between a first end 112 and a second end 116 opposite the first end 112. The second limb 124 extends between the first end 112 and a third end 120 opposite the first end 112. The Y-shape of the second arm 80 allows the first arm 78 to fold between the limbs 122, 124 when the linkage assembly 26 is in the fully collapsed position, as shown in FIG. 12A . This allows the linkage assembly 26 to be stored in a more compact manner (or with a slimmer profile) when the adjustable support 10 is not in use. However, it should be understood that the second arm 80 may be formed in other shapes. For example, the second arm 80 can have more or fewer limbs (e.g., one or three). A first end 122 of the second arm 80 is rotatably coupled to the carrier 92. A pin 126 can be used to secure the second arm 80 to the carrier 92. The second end 116 and the third end 120 are coupled to the mounting plate 84. One or more second pegs 130 can be used to secure the second end 116 and the third end 120 of the second arm 80 to the mounting plate 84. The one or more second pegs 130 are used to secure the second arm 80 to the mounting plate 84. As shown in FIGS. 4 and 11 , the second arm 80 has a plurality of second arm teeth 132. The plurality of second arm teeth 132 extend from the first end 112 ( FIG. 11 ). The plurality of second arm teeth 132 engage an indexing key 144 provided on the carrier 92 as will be described in more detail below.

[0021] 3 and 4 , the mount plate 84 may optionally include a mount plate cover 88. The mount plate 84 is coupled to the first arm 78 and the second arm 80 and attached to the platform 18. The mount plate 84 supports the platform 18, which in turn supports the electronic equipment. As shown in FIG. 4 , one or more first pegs 108 and one or more second pegs 130 are used to secure the mount plate 84 to the first arm 78 and the second arm 80. A plurality of fasteners (not shown) are used to secure the platform 18 to the mount plate 84. In the illustrated embodiment, the mount plate 84 is formed as two pieces attached to the first arm 78 and the second arm 80. In other embodiments, the mount plate 84 may be formed as one piece attached to the first arm 78 and the second arm 80.

[0022] 8 and 11, the carrier 92 serves as one of the linkages of the linkage assembly 96 for adjusting the tilt angle of the platform 18. The carrier 92 also interacts with the post 14 to adjust the height of the platform 18. As noted above, the carrier 92 serves as the "fixed linkage" of the four-bar linkage assembly in that it does not pivot or rotate. The carrier 92 may also be referred to as a housing because such a carrier supports other members of the linkage assembly 26 and may also be used to house other components. In the illustrated embodiment, the carrier 92 has rails 136, friction blocks 140, and an indexing key 144 (FIGS. 8 and 9). However, other embodiments of the carrier 92 may differ from one another such that various combinations of these features may be omitted in a particular embodiment.

[0023] As shown in FIG. 8 , the carrier 92 includes one or more friction blocks 140 that help control the tilting movement of the platform 18. In the illustrated embodiment, two friction blocks 140 are coupled to the housing, although more or fewer friction blocks 140 may be used in other embodiments. The friction blocks 140 engage the first and second arms 78, 80 to provide friction and control the rotation of the first and second arms 78, 80 relative to the post 14. The friction blocks 140 frictionally engage the first and second arms 78, 80 to allow smooth rotation of the first and second arms 78, 80 relative to the post 14. The friction blocks 140 and the center of gravity balance (i.e., shown in FIGS. 13A-13D ) together help maintain the tilted position of the platform 18 without the need for a rigid locking mechanism. Specifically, as shown in FIGS. 13A-13D , the linkage assembly 26 is configured to maintain the center of gravity 184 along a generally straight, horizontal path, referred to as the center of gravity line 188. The center of gravity balancing effect allows the tilt of the platform 18 to be maintained primarily by balancing the linkage assembly 26 relative to one another. In other words, as a user adjusts the tilt of the platform 18, the platform 18 remains at the desired tilt angle due to the balanced forces acting on the linkage assembly and the consistent center of gravity 184. The friction block 140 helps maintain this balance of forces by creating a frictional force that reduces the tendency of the first arm 78 and the second arm 80 to rotate. In other words, the linkage assembly is configured to maintain the tilt angle of the platform based on the balance of forces and without the use of a locking mechanism.

[0024] As shown in FIG. 11 , the carrier 92 may optionally include an indexing key 144. The indexing key 144 is coupled to the carrier 92. In the illustrated embodiment, two indexing keys 144 are coupled to the carrier 92. The indexing key 144 engages the plurality of first arm teeth 110 and the plurality of second arm teeth 132 ( FIG. 11 ). The indexing key 144 has a lip 146 that engages the plurality of first arm teeth 110 and the plurality of second arm teeth 132. The indexing key 144 provides the user with a tactile feedback sound of the rotation of the first and second arms 78, 80 relative to the post 14. It should be understood that in some embodiments, there is only one indexing key 144 and one set of teeth 110, 112 used to generate the tactile feedback. Alternatively, in some embodiments, this feature may be omitted entirely. Additionally, in some embodiments, the indexing key 144 and teeth 110, 112 can provide functionality beyond tactile feedback; they can be used as a ratchet pawl mechanism to limit (i.e., lock) the rotation of the first arm 78 and the second arm 80. In some embodiments, the linkage assembly 26 need not include the teeth 110, 112 and the indexing key 144, as these are optional features.

[0025] As described above, the carrier 92 also interacts with the post 14 to adjust the height of the ratchet. The carrier 92 is movably positioned within the post cavity 44. The carrier 92 may include one or more rails 136, one or more friction blocks 140, and / or one or more indexing keys 144 (e.g., one, two, three, or four). The illustrated carrier 92 has an outer surface 138 that includes the rails 136. The rails 136 extend along the outer surface 138 of the carrier 92. In the illustrated embodiment, the carrier 92 has two rails 136, although a greater or lesser number of rails can be used. The rails 136 tilt relative to the track 74 of the post 14 to guide movement of the carrier 92 within the post 14 along the longitudinal axis 54 between the first end 46 and the second end 50.

[0026] 10 and 11 show a friction grip 148 positioned within the carrier 92. The friction grip 148 helps control the vertical position of the linkage assembly 26 relative to the post 14, thus controlling the height of the platform 18. Specifically, the friction grip 148 provides a frictional force to allow movement (e.g., in an upward direction) or restrict movement (e.g., in a downward direction) of the carrier 92 along the longitudinal direction 54. The friction grip 148 uses friction to maintain the carrier 92 at a desired height within the post 14 and selectively allow movement of the carrier 92 within the post 14. To move the carrier 92 in a downward direction, a force is applied to overcome the frictional force of the friction grip 148, thus allowing movement of the linkage assembly 26 to a lower height. For example, a downward force can be applied to the platform 18 to overcome the frictional force of the friction grip 148, thereby allowing a user to lower the height of the platform 18.

[0027] In the illustrated embodiment, the friction grips 148 may move more freely in an upward direction than in a downward direction. For example, the friction grips 148 may move more freely in an upward direction, requiring a greater force to be applied to move the carrier 92 downward. Thus, in this example, it may be easier to move the platform 18 in an upward direction than to move the platform 18 downward. However, in other embodiments, the amount of friction applied by the friction grips 148 may be equal in both the upward and downward directions. It should be understood that there are many different ways to configure the friction grips 148 that can apply a friction force to maintain the linkage assembly 26 and platform 18 at a desired height, while also applying a force to overcome the friction of the friction grips 148 to allow selective movement of the linkage assembly 26 and platform 18. One exemplary embodiment is described below.

[0028] The exemplary friction grip 148 shown in FIG. 10 includes a bearing 160, e.g., a one-way bearing, for controlling movement of the carrier 92 within the post 14. While various configurations are possible, the illustrated friction grip 148 includes an eyelet 152, a pin 156, a bearing 160, a nut 164, and a screw 168. The eyelet 152 includes an eyelet bore 154 that receives the pin 156 and bearing 160. The bearing 160 may be a one-way bearing, such that the bearing 160 rotates freely in one direction but is restricted (or partially restricted) from rotating in the opposite direction. The nut 164 abuts the eyelet 152. A screw 168 threadably engages the eyelet 152 and the nut 164. The screw 168 is rotatable to adjust the amount of friction force around the pin 156 and bearing 160.

[0029] 8 and 9, the friction grip further includes a pinion 172. The pinion 172 helps enable smooth and consistent movement of the linkage assembly 26 along the post 14. In particular, the pinion 172 is coupled to the pin 156 of the friction grip 148. The pinion 172 may also be referred to as a gear or a helical gear. The pinion 172 includes a pinion bore having a plurality of teeth 174. The pinion bore of the pinion 172 receives the pin 156. The pinion 172 rotatably engages the rack 70 of the post 14. The plurality of teeth 174 mesh with corresponding teeth of the rack 70 positioned within the post 14.

[0030] In operation, friction grip 148 controls rotation of pinion 172 in one rotational direction. Bearing 160 allows pinion 172 to rotate freely in a first rotational direction that allows linkage assembly 26 to move relative to post 14 (e.g., upward toward first end 46 of post 14). Bearing 160 prevents pinion 172 from rotating freely in a second rotational direction opposite the first rotational direction, thereby causing linkage assembly 26 to remain stationary (e.g., preventing or partially preventing movement in a downward direction toward second end 50 of post 14). In other words, friction grip 148 controls resistance from a downward force applied to linkage assembly 26 (e.g., a force applied generally parallel to axis 54 toward second end 50 of post 14). Friction grip 148 is rated for a weight typical of electronic equipment (e.g., 3-7 pounds (1.4-3.2 kg)). When a user places an electronic device on platform 18, friction grip 148 prevents linkage assembly 26 from moving toward base 12. When a user wants to adjust the height of the electronic device relative to the desktop, the user applies a downward force that overcomes the set weight rating of friction grip 148 to move platform 18 closer to base 12. In some embodiments, movement of pinion 172 along rack 70 can engage linkage assembly 26 with post 14 at a first position relative to longitudinal axis 54 of post 14 and a second position relative to longitudinal axis 54 of post 14. The second position is different from the first position.

[0031] 12A-12C, the linkage assembly 26 and the platform 18 are movable to different heights along the post 14. Specifically, the linkage assembly 26 is movable axially relative to the longitudinal axis 54 of the post 14 (FIG. 2). Movement of the linkage assembly 26 allows the platform 18 to be shifted to different heights relative to the post 14. When a user wishes to adjust the vertical position of the platform 18, the user grasps an edge of the platform 18 and applies an upward or downward force to the platform 18. When an upward or downward force is applied, the platform 18 can move relative to the post 14. In the illustrated embodiment, the platform 18 of the adjustable support 10 is adjustable to multiple vertical positions along the post 14 relative to the base 12.

[0032] 13A-13D, the linkage assembly 26 and platform 18 are also adjustable for different tilt angles and / or vertical positions relative to the post 14. FIGS. 13A-13D show the platform 18 at several different tilt angles. FIG. 13A shows the adjustable support 10 in a fully collapsed position, in which the platform 18 is positioned near the post 14 and oriented generally in alignment with the longitudinal axis 54. FIGS. 13B-13D show the adjustable support 10 in various extended positions, in which the platform 18 is pulled away from the post 14 and tilted relative to the longitudinal axis 54. When a user wishes to adjust the horizontal position of the platform 18 and / or the tilt angle of the platform 18, the user grasps the edge of the platform 18 and pulls or pushes the platform horizontally relative to the post 14 (e.g., to the left or right in FIG. 12). When a pushing or pulling force is applied, the first arm 78 and the second arm 80 of the linkage assembly rotate relative to the carrier 92 to move the platform 18 forward or backward relative to the post 14. The platform 18 is adjustable from a first position in which the platform is angled obliquely relative to the post 14 at a first angle to a second position in which the platform is angled obliquely relative to the post 14 at a second angle that is greater than the first angle. In the illustrated embodiment, the platform 18 is adjustable to a number of different positions that adjust the angle of inclination to various oblique angles relative to the post 14.

[0033] 13A-13D also show the adjustable support 10 supporting the exemplary electronic device 180 in multiple tilt positions (a)-(d) in which the center of gravity 184 remains generally located along a straight horizontal path. When a user adjusts the tilt angle of the platform 18 from the first position (a) to the fourth position (d), the user pulls the platform 18 in a first horizontal direction (e.g., to the right in FIG. 13). The linkage assembly 26, and particularly the first and second arms 78, 80, maintain the center of gravity 184 generally along the center of gravity line 188 in positions (a)-(d). In other words, the center of gravity 184 of the electronic device 180 does not deviate significantly from the center of gravity line 188 in the different tilt positions (a)-(d). In some embodiments, the center of gravity 184 may deviate approximately ±5 mm from the center of gravity line 188 in the different tilt positions (a)-(d). Rather, the linkage assembly 26 stabilizes the electronics 180 during tilt adjustment of the platform 18 .

[0034] The axial and rotational movement of the adjustable support 10 allows for a complete ergonomic solution, while allowing the user to set the electronic device to a desired vertical height, horizontal position, and tilt angle for increased productivity. The adjustable support 10 also allows for the use of separate computer peripherals (e.g., a mouse and keyboard).

[0035] FIG. 14 illustrates another embodiment of an adjustable support 210 configured to support an electronic device, such as a computer, laptop, tablet, mobile phone, or other device. The adjustable support 210 is coupled to a base 12. The base 12 may have a horizontal base 12, such as a desktop or tabletop (FIG. 14). In other embodiments, the base 12 may include a vertical base, such as a wall or post. The base 12 illustrated in FIG. 14 may be substantially similar to the base 12 described above with reference to FIG. 1.

[0036] 14 and 15, adjustable support 210 includes a post 214 connected to base 12, a platform 218 including a platform ledge 222, and a linkage assembly 226 movably engaged with post 214. Post 214 includes a post housing 30 having a post top plate 234, a post first housing portion 238, and a post second housing portion 242. Post top plate 234, post first housing portion 238, and post second housing portion 242 together define a post cavity 244. Post 214 has a first end 246 and a second end 250 opposite first end 246. A longitudinal axis 254 extends through the center of post 214 between first end 246 and second end 250. The post 214 has a length defined along a longitudinal axis 254 between a first end 246 and a second end 250 .

[0037] 14 and 15, post 214 includes a post slot 258. In other words, post first housing portion 238 and post second housing portion 242 define post slot 258. As will be described in more detail below, linkage assembly 226 extends through post slot 258 to a remote location away from post 214. Post 214 may include a universal serial bus (USB) port or power hub 62 to provide connectivity or power to the electronics described above with respect to adjustable support 10. Post 214 further includes a rack 262 positioned within post 214, and particularly within post cavity 244 (FIG. 16).

[0038] As shown in FIGS. 16 and 17 , the post 214 has rails 264. In the illustrated embodiment, the post 214 has two rails 264. In other embodiments, the post 214 can have one or more rails 264 (e.g., one, two, three, or four). The rails 264 may be positioned within the post 214, particularly within the post cavity 244. The rails 264 extend from near the first end 246 to the second end 250 of the post 214. In the illustrated embodiment, the rails 264 may extend along a majority of the length of the post 214. As described in more detail below, the linkage assembly 226 includes a channel 310 that mates with the rails 264 to guide the linkage assembly 226 within the post 214 relative to the longitudinal axis 254 between the first end 246 and the second end 250.

[0039] 14 , the platform 218 is movably coupled to a linkage assembly 226. The platform 218 may be substantially similar to the platform 218 described above. The platform 218 is configured to support an electronic device. The platform 218 may have a square, rectangular, or other suitable shape for supporting the electronic device. The platform 218 may have a ridge or gripping surface to maintain the electronic device on the platform 218. The platform 218 further includes a platform ledge 222 extending from the platform 218. The platform ledge 222 may also be referred to as a lip. The platform ledge 222 is configured to prevent the electronic device from sliding off the platform. In the illustrated embodiment, the platform ledge 222 may extend at an angle of approximately 90° relative to the platform 218. In other embodiments, the platform ledge 222 may extend at an angle relative to the platform 218 .

[0040] 15 and 16 show linkage assembly 226 movably engaged with post 214. Linkage assembly 226 includes a first arm 266, a second arm 270, and a carrier 274. First arm 266 has a first end 278 and a second end 286 opposite first end 278 (FIG. 18). First end 278 of first arm 266 is rotatably coupled to carrier 274. A pin 282 is used to secure first arm 266 to carrier 274.

[0041] 17 and 18 , the second arm 270 is rotatably coupled to the first arm 266. The second arm 270 has a first end 290 and a second end 294 opposite the first end 290 ( FIG. 18 ). The first end 290 of the second arm 270 is rotatably coupled to the carrier 274. A pin 298 is used to secure the second arm 270 to the carrier 274. The second arm 270 has an actuator 302 ( FIGS. 17 and 18 ). The actuator 302 may also be referred to as a button or a lever. The actuator 302 extends from the second end 294 of the second arm 270. Movement of the actuator 302 rotates the second arm 270 relative to the first arm 266, thereby adjusting the angular position of the first arm 266, to which the platform 218 is attached, relative to the post 214.

[0042] As shown in Figures 15 and 16, the carrier 274 is movably positioned within the post 214. In other words, the carrier 274 is movably positioned within the post cavity 244. The carrier 274 may also be referred to as a housing. The carrier 274 has channels 310 (Figures 16 and 17). In the illustrated embodiment, the carrier 274 has two channels 310. In other embodiments, the carrier 274 may have one or more (e.g., one, two, three, or four) channels 310. The carrier 274 has an outer surface 312 that defines the channels 310. The channels 310 extend along the outer surface 312 of the carrier 274. The channel 310 of the carrier 274 receives the rail 264 of the post 214 to guide the carrier 274 within the post 214 along the longitudinal axis 254 between the first end 246 and the second end 250. In other words, the rail 264 of the post 214 mates with the channel 310 of the carrier 274 to guide the linkage assembly 226 within the post 214 along the longitudinal axis 254 between the first end 246 and the second end 250.

[0043] 16 and 17 show the friction grip 314 positioned within the carrier 274. The friction grip 314 may be substantially similar to the friction grip 148 described above. The friction grip 314 includes an eyelet 318, a pin 326, a bearing 330, a nut 334, and a screw 338. The eyelet 318 includes an eyelet bore 322 that receives the pin 326 and the bearing 330. The bearing 330 may be a one-way bearing, such that the bearing 330 rotates freely in one direction. The nut 334 abuts the eyelet 318. A screw 338 threadably engages the eyelet 318 and the nut 334. The screw 338 is rotatable to adjust the amount of friction force around the pin 326 and the bearing 330.

[0044] 17 shows a pinion 342 coupled to the friction grip 314. In particular, the pinion 342 is coupled to the pin 326 of the friction grip 314. The pinion 342 may also be referred to as a gear. The pinion 342 has a pinion hole, and the pinion has a plurality of teeth 346. The pinion hole of the pinion 342 receives the pin 326. The pinion 342 is rotatably engaged with the rack 262 of the post 214. The plurality of teeth 346 mesh with the rack 262 of the post 214.

[0045] In operation, friction grip 314 controls rotation of pinion 342 in one rotational direction. Friction grip 314 may function similarly to friction grip 148. Pinion 342 is free to rotate in a first rotational direction that allows linkage assembly 226 to move relative to post 214 (e.g., toward first end 246 of post 214). Pinion 342 is not free to rotate in a second rotational direction opposite the first rotational direction, thereby causing linkage assembly 226 to remain stationary (e.g., not move toward second end 250 of post 214). Friction grip 314 restricts the second rotational direction of pinion 342. In other words, friction grip 314 controls resistance from a downward force applied to linkage assembly 226 (e.g., a force applied generally parallel to axis 54 toward second end 250 of post 214). Friction grip 148 is set to a weight rating typical of the weight of an electronic device (e.g., 3-7 pounds (1.4-3.2 kg)). When a user places an electronic device on platform 218, friction grip 314 engages the pinion and prevents linkage assembly 226 from moving toward base 12. When a user wants to adjust the height of the electronic device relative to the desktop, the user applies a downward force that overcomes the set weight rating of friction grip 314 to move platform 218 closer to base 12.

[0046] The adjustable support 210 is movable axially along the longitudinal axis 54 of the post 214 ( FIG. 14 ). A linkage assembly 226 allows the platform 218 to move axially along the post 214. If a user wishes to adjust the vertical position of the platform 218, the user grasps the edge of the platform 218 and applies an upward or downward force to the platform 218. When an upward or downward force is applied, the platform 218 can move relative to the post 214. In the illustrated embodiment, the platform 218 of the adjustable support 210 is adjustable at multiple vertical positions along the post 214 relative to the base 12. If a user wishes to adjust the rotational position of the platform 218, the user presses the actuator 302 against the second arm 270 to rotate the platform 218 relative to the post 214. When actuator 302 is depressed, second arm 270 disengages from carrier 274, thereby allowing first arm 266, to which platform 218 is attached, to rotate relative to post 14. Once the desired position is set, second arm 270 engages carrier 274, thereby allowing first arm 266, to which platform 218 is attached, to remain stationary relative to post 214. In the illustrated embodiment, platform 18 is adjustable at multiple angular positions relative to post 14.

[0047] 19 and 20 illustrate another embodiment of an adjustable support 410. The adjustable support can be used in conjunction with the base 12 described above. The adjustable support 410 includes a post 414 connected to the base 12, a platform 418, and a hinge assembly 422 that movably couples the platform 418 to the post 414. The post 414 has a first end 426 and a second end 430 opposite the first end 426. An axis 434 extends through the center of the post 414 between the first end 426 and the second end 430. The axis 434 may also be referred to as the longitudinal axis. The post 414 has a length determined along the axis 434 between the first end 426 and the second end 430.

[0048] As shown in FIG. 20 , the post 414 further includes a track 438 extending from near the first end 426 toward the second end 430. In the illustrated embodiment, the track 438 extends along a portion of the length of the post 414. In other embodiments, the track 438 extends the entire length of the post 414. In the illustrated embodiment, the post 414 includes two tracks 438. In other embodiments, the post 414 can include one or more tracks 438 (e.g., one, two, three, four, or five tracks). The track 438 includes an edge 442 that engages the hinge assembly 422. The hinge assembly 422 engages the edge 442 of the track 438 to guide the hinge assembly 422, to which the platform 418 is attached, relative to the axis 434 between the first end 426 and the second end 430.

[0049] Continuing with reference to FIG. 19 , a platform 418 is movably coupled to the post 414. The platform 418 is configured to support an electronic device. The platform 418 may be square or rectangular in shape. The platform 418 includes a platform recess 454. As shown in FIG. 19 , the platform 418 has a ledge 458 extending from an edge 462 of the platform 418. The ledge 458 may also be referred to as a lip. The ledge 458 is configured to prevent the electronic device from sliding off the platform 418. The ledge 458 may extend at an angle of approximately 90° relative to the platform 418. In other embodiments, the ledge 458 may extend obliquely relative to the platform 418.

[0050] 20 and 21 show a hinge assembly 422 that is movably coupled to a post 414. The hinge assembly 422 includes a mount 466 and a hinge 470. The mount 466 movably couples the hinge 470, to which the platform 418 is attached, to the post 414. The mount 466 extends into the track 438. The mount 466 may have a lip, rail, or protrusion that engages with the track 438. The mount 466, to which the hinge 470 is coupled, is movable relative to the axis 434 of the post 414. In other words, the hinge assembly 422, to which the platform 418 is attached, is movable relative to the axis 434 of the post 414.

[0051] 20 and 21 , hinge 470 is rotatably coupled to mount 466. A pin 490 is used to secure hinge 470 to mount 466. Hinge 470 includes a hinge plate 474 and a hinge housing 478. Hinge plate 474 is attached to hinge housing 478 to form a hinge cavity 482. Hinge plate 474 includes a plate recess 486 that receives an actuator 494, as described in more detail below.

[0052] 20 and 21 show an actuator 494 positioned within the hinge cavity 480. The actuator 494 may also be referred to as a button. The actuator 494 is configured to selectively move the hinge 470, to which the platform 418 is attached, from a first, open position to a second, folded position. As shown in FIG. 20 , the actuator 494 has a generally rectangular shape with an angled surface 498. The actuator 494 extends through the plate recess 486 and the platform recess 454 so that the angled surface is visible when the platform 418 is attached to the hinge assembly 422. The angled surface 498 is configured to receive a user's thumb or other finger. The actuator 494 is movable (i.e., with a downward force) to adjust the position of the platform 418 relative to the post 414. The platform 418 is adjustable between a first position and a second position. In the first position, the platform 418 is angled obliquely relative to the post 414. In the second position, the platform 418 is approximately parallel to the post 414. In the second position, the platform 418 is folded relative to the post 414.

[0053] In operation, the adjustable support 410 is configured to support an electronic device. The adjustable support is movable relative to the axis 434 of the post 414. The adjustable support 410 is rotationally movable relative to the axis 434 of the post 414. The hinge assembly 422 allows the platform 418 to rotate relative to the post 414. Movement of the actuator 494 (e.g., with a downward pressure) allows the hinge 470 and platform 418 to rotate together relative to the post 414. In particular, the adjustable support 410 is movable from a first position in which the platform 418 is angled obliquely relative to the post 414 to a second position in which the platform 418 is folded relative to the post 414. In other words, the platform 418 is approximately parallel to the post 414 in the second position. The adjustable support 410 is configured to support the electronic device in the first position. The adjustable support 410 is configured for storage in a second position or to reduce desktop space. The axial or rotational movement of the adjustable support 410 allows for a complete ergonomic solution and allows the user to position the electronic device as desired for improved productivity. The adjustable support 10 also allows for the use of separate computer peripherals (e.g., a mouse and keyboard) to further improve ergonomics and productivity.

[0054] FIG. 22 illustrates a clamp 500 coupled to the adjustable support base 12. The clamp 500 can be used with the adjustable supports 10, 210, and 410 described above. The clamp 500 is coupled to the second ends 50, 250, and 430 of the posts 14, 214, and 414, respectively. In one embodiment, the clamp 500 is secured to the edge of a desk or table (e.g., a horizontal base). In another embodiment, the clamp 500 penetrates the desk or table. The clamp 500 includes a clamp pin 508 configured to be inserted into the post 14, 214, and 414. The clamp pin 508 is used to secure the clamp 500 to the post 14, 214, and 414.

[0055] As shown in FIG. 22 , the clamp 500 has a C-shaped bracket 512 that defines a channel 516 that receives the base 12. In the illustrated embodiment, the C-shaped bracket 512 may be integrally formed as a single structure. In some embodiments, the C-shaped bracket 512 may be formed as two or more separate structures. In other embodiments, the bracket 512 may include an L-shaped bracket integrally formed as a single structure. In yet other embodiments, the bracket 512 may include an L-shaped bracket formed as two or more separate structures. In one example, the channel 516 receives a table or desk. The clamp 500 has a fastener 520 that extends into the channel 516 and secures the adjustable support to the base 12. The fastener 520 has a flange 524 with a flat surface 528 that engages the base 12, a shaft 532, and a head 536. The head 536 may be a twist knob that allows a user to tighten or loosen the clamp 500. In other embodiments, head 536 may be a screw head that can accept a tool to tighten or loosen clamp 500. When the adjustable support is positioned for use, a user can use the head to tighten clamp 500 and secure the adjustable support to base 12. In other embodiments, the adjustable support may have other means for coupling to base 12.

[0056] 23 and 24, in another embodiment, the clamp 500 further includes a tab 540, which may also be referred to as an extendable tab. The tab 540 includes a slot 544 that receives the bracket 512 of the clamp 500. During installation, a clamp pin 508 is used to secure the tab 178 to the post 14, 214, or 414. In operation, the adjustable support may be movable in a forward or rearward direction relative to the base 12. The tab 540 may be movable between a retracted configuration and an extended configuration (FIGS. 23 and 25). The tab 540 may be movable to the extended configuration so that the adjustable support is positioned a first distance relative to the edge of a desk or table. The tab 540 may also be movable to the retracted configuration so that the adjustable support is positioned a second position relative to the edge of a desk or table. Tab 540 can be moved to an extended configuration such that the adjustable support is positioned at a first distance relative to the edge of a desk or table, allowing for further adjustability of the adjustable support to provide a complete ergonomic solution and increase productivity.

[0057] 25 , in another embodiment, the bracket 512 of the clamp 500 further includes a disk 548, which may also be referred to as a swivel disk. In the illustrated embodiment, the disk 548 is integrally formed with the bracket 512. In another embodiment, the disk 548 is formed separately and attached to the bracket 512 by bonding, welding, fastening, or other connecting means. A clamp pin 508 is used to secure the disk 548 to the post 14, 214, or 414. The disk 548 allows for further adjustability of the adjustable support to provide a complete ergonomic solution and improve productivity.

[0058] During installation, the post 14, 214, 414 is attached to the disc 548. In operation, the adjustable support is rotatable relative to the base 12. The adjustable support is rotatable 360° relative to the base 12. In other embodiments, the adjustable support can rotate 45°, 90°, 120°, 180°, or 270° relative to the base 12. In still other embodiments, the adjustable support can rotate between 45° and 360° relative to the base 12.
