Laptop holder for extension arm

[0001] The present application is a continuation-in-part of U.S. Design patent application Ser. No. 29/264,184, entitled LAPTOP HOLDER, filed Aug. 4, 2006 and U.S. Design patent application Ser. No. 29/264,185, entitled LAPTOP HOLDER, filed Aug. 4, 2006, the entire disclosures of which are hereby expressly incorporated by reference herein.

[0002] The present invention relates to a device for use in supporting and displaying electronic devices. More particularly, the present invention is particularly adapted for use as a support platform for use with laptop computers and other portable computing devices.

[0003] Laptop computers and similar portable devices are often used in home and office environments, and may be placed on a desk as a stand alone device or in conjunction with a docking station. Unfortunately, the convenience in size and portability may not be matched by proper ergonomics in the placement of such devices. For instance, the keyboard should be positioned a comfortable distance from the user to avoid wrist, back and/or neck strain, but the display should be positioned at an appropriate distance to avoid eye strain. These requirements may conflict, causing the user to choose between undesirable alternatives.

[0004] In order to address these conditions, it is possible for a user to connect an external monitor, an external keyboard and/or an external mouse to the laptop computer. The monitor, keyboard and mouse may be separately mounted and adjusted to achieve desired ergonomic effects.

[0005] For example, one solution is to place the keyboard and/or mouse in a sliding drawer which can be closed when the keyboard or mouse is not in use. In another solution, a monitor stand can be used to elevate the display over other equipment on a desk. While this may free up space on the workspace, it often places the equipment in undesirable locations. For example, access to the keyboard and mouse may require repeated opening and closing of the drawer.

[0006] A further solution employs a mechanical extension arm to support the monitor or the keyboard. One such monitor extension arm is shown and described in U.S. Pat. No. 6,478,274, entitled “Arm Apparatus for Mounting Electronic Devices,” which is fully incorporated by reference herein. Another type of monitor extension arm is shown and described in U.S. Pat. No. 6,409,134, entitled “Arm Apparatus for Mounting Electronic Devices with Cable Management System,” which is fully incorporated by reference herein. An example of a keyboard extension arm/support mechanism is shown and described in U.S. Pat. No. 6,076,785, entitled “Ergonomic Sit/Stand Keyboard Support Mechanism,” which is fully incorporated by reference herein.

[0007] However, the use of a separate monitor, mouse and/or keyboard leads to multiple devices that can take up valuable real estate on, in, or over the user's workspace. Furthermore, the cost of the separate components may be prohibitive, especially for space-saving monitors such as flat panel displays, wireless keyboards and wireless mice.

[0008] Therefore, it is desirable to provide another solution to ergonomic and other problems. For instance, it is possible to provide a docking station or support device for use with the laptop computer itself. The support device may take the form of an extension arm adapted for handling laptop computers. An example of an extension arm for use with laptop computers is shown and described in U.S. Patent Publication No. 2004/0007651, entitled “Universal Support for Electronic Devices,” which is fully incorporated by reference herein.

[0009] While such laptop extension arms are suitable for supporting laptop computers, a need exists for enhanced devices to securely and adjustably support portable electronic devices in an ergonomic matter.

FIG. 8F illustrates a side view of the slider clip 106b, the other side being a mirror image thereof.

[0065] The slider clip 106b may comprise any number of materials such as plastics or metals, or combinations thereof. Preferably, the slider clip 106b comprises a plastic, which may be molded or otherwise fabricated as a single piece. More preferably, the slider clip 106b is made of the same material or materials as the main body clip 106a.

[0066] As best seen in FIGS. 8B and 8D, the second side 252 preferably includes a pair of sidewalls 260 each having a channel member 262 therealong. The channel members 262 are configured to slideably couple to the pair of channel members 228 on the main body clip 106a. The second side 252 desirably also includes at least one, and more preferably a series of receptacles 264 disposed between the sidewalls 260. The receptacles 264 are dimensioned to receive the tab 232 or other projection on the main body clip 106a.

[0067] Assembly of the holder unit 100 will now be described with reference to FIGS. 9-11. As shown in FIGS. 9A-E, the first support member 102a and the second support member 102b may be fitted together in the case where the support unit 102 is not integrally formed as a single component. Specifically, the connectors 136 on the second face 134 of the second support member 102b may be press fit to securely engage the pair of receptacles/through holes 143 on the first pair of extensions 142 of the first support member 102a. Of course, it should be appreciated that the connectors 136 may be part of the first support member 102a and the receptacles/through holes 143 may be disposed on the second support member 102b. Other fastening means may be employed to connect the first support member 102a and the second support member 102b, such as clips, clasps, hasps, threaded fasteners such as screws or bolts, etc. The second pair of receptacles/through holes 145 on the first support member 102a is aligned with the receptacles/through holes 138 of the second support member 102b.

[0068] As seen in FIGS. 9A and 9C, the release plate 108 couples to the adapter section 146 of the first support member 102a. The connectors 200 on the rear side 184 of the release plate 108 engage the receptacles 152 in the adapter section 146, and the bosses 194 protrude away from the rear side 184. In an alternative embodiment, the rear side 184 of the release plate 108 may include receptacles and the adapter section 146 may include connectors to attach thereto. In fact, any type of fastening means is possible between the release plate 108 and the adapter section 146. The release plate 108 may be permanently affixed to the adapter section 146. The post 188 on the release plate 108 is preferably at least partly received in the opening/recess 160 of the adapter section 146. The pair of arms 196 preferably contact the pair of surfaces 172a,b. At this point, the main body 180 and the arms 196 of the release plate 108 preferably lie along the same plane.

[0069] FIGS. 10A-D illustrate how the clip members 106 attach to both the arm members 104 and the support member 102, and how the arm members 104 attach to the support member 102. The main body clips 106a may be first attached to the arm members 104 and the support member 102, and then the slider clip members 106b may be connected to respective ones of the main body clips 106a. Alternatively, the slider clip members 106b may be connected to the main body clips 106a first and then the pairs of main body clips 106a and slider clip members 106b may be attached to the arm members 104 and the support member 102.

[0070] In use, the slider clip 106b is adapted to slide up and down along the channel members 228 on the main body clip 106a, and the tab 232 is received within one of the receptacles 264. The slider clip 106b may be positioned by a user to an appropriate height so that the tab 256 on the first end 254 of the slider clip engages a surface of the laptop computer or other device which is being supported. Each main body clip 106a may be positioned along either the clip receiving portion 127 or one of the arm members 104.

[0071] While the main body clips 106a and the slider clips 106b are preferred, it should be understood that single or multi-piece clips of other configurations may be employed in place of or in conjunction with the main body clips 106a and the slider clips 106b. In alternative embodiments, different types of connectors may be used. For instance, a retaining bar and/or a retaining strap may be used in place of some or all of the clip members 106 to secure the laptop computer or like device to the holder unit 100.

[0072] As discussed above with respect to FIG. 2, the holder unit 100 may also include spring devices 110 and adjustment members 112. The spring devices 110 are preferably coiled or wound springs. The adjustment members 112 are preferably threaded knobs. While not required, the spring devices 110 are preferably placed about the shafts of the threaded knobs, as shown in FIGS. 10A and 10B. The threaded knobs are then attached to the first and second support members 102a and 102b. Specifically, the shafts of the threaded knobs are inserted through the receptacles/through holes 138 and the receptacles/through holes 145. The knob threads desirably engage with threads on one or both of the receptacles/through holes 138 and the receptacles/through holes 145, as well as with threads on the receptacle/through hole 218 of the arm member 104.

[0073] Other types and configurations of the adjustment members 112 may be provided. For instance, as shows in FIGS. 11B-C, locking tabs 112, or other connectors may be used to secure the arm members 104 to the first support member 102a and/or to the second support member 102b. If locking tabs are employed, the tabs may engage a portion of the arm members 104 to prevent movement thereof.

[0074] For instance, as shown in FIGS. 13A-E, the locking tab 112, preferably includes a cover 113 and a shaft 115, which may be threaded as with the shaft of adjustment member 112. Desirably one or more tab members 117 are provided. A grip portion 119 may also be included. As with the adjustment member 112, the threaded shaft may be inserted through the receptacles/through holes 138 and the receptacles/through holes 145. The threads of the shaft 115 desirably engage with threads on one or both of the receptacles/through holes 138 and the receptacles/through holes 145, as well as with threads on the receptacle/through hole 218 of the arm member 104. The one or more tab members 117 may engage with a portion of the support member 102 to prevent rotation/movement of the locking tab 112₁.

[0075] In an alternative, the arm member 104 may include a shaft portion. In this case, the shaft 115 may be omitted from the locking tab, as shown with locking tab 112₂ of FIGS. 14A-E. Here, a receptacle or through hole 121 may be used to receive the shaft of the arm member 104. The receptacle/through hole 121 may or may not be threaded.

[0076] Returning to FIG. 10, FIG. 10D illustrates a cutaway view along the A-A line of FIG. 10C, and shows engagement of the adjustment member 112 with the first and second support members 102a and 102b, as well as with the arm member 104. Also shown in the cutaway view is the engagement of the interlocking teeth 132 and 216. Depending upon the threading of the adjustment member 112 (or locking tab 112₁), a user may tighten or loosen the adjustment member 112 by turning it clockwise or counterclockwise. Upon loosening, the arm member 104 may be adjusted to a desirable position to receive the laptop computer or other user device. Each arm member 104 may be individually pivotally adjusted by rotation about axis A. This permits the user to arrange the holder unit 100 in a specific configuration to support the laptop or other device, regardless of its shape.

[0077] Once the laptop computer 80 or other electronic device is securely on the holder unit 100 by the clip members 106 or other connectors, the user may freely position the laptop in a desired location and orientation by moving the extension arm assembly 20 and the tilting device 60 as desired. The extension arm assembly 20 may include a cable management system in order to hide a power cable and/or data cables which may connect the laptop to external devices such as a keyboard or mouse.

[0078] The user may remove the laptop computer 80 from the holder unit 100 by disengaging the clip members 106 or other connectors from the laptop. It is also possible to leave the laptop secured to the holder unit 100 while disengaging from the extension arm assembly 20 and the tilting device 60. For instance, the user preferably pulls, pushes or otherwise causes the post 188 or other release mechanism to move within the opening 160 of the adapter section 146 and toward or away from the laptop computer 80. This, in turn, causes the main body 180 to deflect or move away from the tilting device 60. The bosses 194 or other projections of the release plate 108 thus disengage from the holes/recesses 152 of the adapter section 146. Now the laptop 80 and the holder unit 100 may be removed, enabling the user to place them on another extension arm assembly 20 and tilting device 60, or to replace them with another laptop 89 and holder unit 100.

[0079] While the release plate 108 permits a user to rapidly disengage the holder unit 100, and the user device, if attached, from the adapter section 146, there may be situations when it is desirable to prevent inadvertent or unwanted disengagement. For example, in a high traffic environment, one would like to discourage unauthorized personnel from tampering with the equipment. A fastener or other engagement mechanism may be used to secure the release plate 108 to the adapter section 146. Thus, it becomes difficult for an unauthorized user to quickly release the holder unit 100 and the user device from the tilting device 60. Alternatively, the release plate 108 may be omitted and the holder unit 100 may be directly or indirectly secured to the tilting device 60, the extension arm assembly 20, or other support/adjustment device.

[0080] FIGS. 11A-B illustrate perspective views of the assembled holder unit 100 employing threaded knobs 112, and FIGS. 11C and 11D illustrate perspective views of the assembled holder unit 100 employing locking tabs 1121. As shown in FIGS. 11A and 1D, covers or caps 114 may be used to decoratively cover the receptacles/through holes 143. FIGS. 12A-D illustrate a perspective view, a side view, a top view and a bottom view, respectively, of the cover 266. As shown, the cover 266 may include a body portion 268 sized to fit or otherwise cover the receptacle/through hole 143. The cover 266 may also include a shaft 270 that is received within the receptacle/through hole 143. The shaft 270 may have first and second portions 270a and 270b of different diameters. The cover 266 may comprise, for example, rubber, plastic or metal, although other materials or combinations thereof may be used.
