DETAILED DESCRIPTION

[0017] An electronic device may include a touch pad to input data, navigate menus and/or detect user gestures during use of the electronic device. The electronic device may include a housing that defines an opening into which the touch pad is placed to connect the touch pad to the electronic device.

[0018] The touch pad may include comers that are adjacent an edge of the opening defined by the housing. Steps may be created between some of these corners of the touch pad and the adjacent edge. These steps may be perceived by some electronic device users as an indication of low quality. Some electronic device users may also or alternatively find such steps to be aesthetically displeasing. Such steps may additionally or alternatively be uncomfortable to some electronic device users when they encounter then) during use of a touch pad

[0019] Examples directed to helping to minimize these steps between the comers of a touch pad and the adjacent edge of an opening of an electronic device are shown in FIGs. 1- 14 These examples attempt to address the above-described, technical challenges associated with such steps by allowing the corners of a touch pad that are creating these steps to be selectively moved in either a direction toward or away from a first surface of the housing so that these corners may be made substantially flash with the adjacent edge of the bousing.

[0020] As used herein, the term "electronic device" represents, but is not necessarily limited to, a notebook computer, computing device accessory such as a discrete keyboard, tablet, phone, personal digital assistant, audio player, wearable device, or combination thereof. As used herein, the terms "include" "includes", "including", "have", "has", "having" and variations thereof, mean the same as the terms "comprise", "comprises", and "comprising'*, or appropriate variations thereof.

I , electronic device 12 includes a touch pad 14 adjacent an edge 16 of an opening 18 defined by a housing 20 of electronic device 12. As can also be seen in FIG. 1. apparatus 10 additionally includes an adjustment mechanism 22 to selectively move a first comer 24 and a second corner 26 of touch pad 14 that are opposite first side 28 of touch pad i 4 toward and away frorn front surface 30 of housing 20 so that respective first and second corners 24 and 26 are substantially flush with adjacent edge 16, as discussed more fully below. As can additionally be seen in FIG. 1 , electronic device 12 includes a keyboard 32 to input alphanumeric characters, a$ welt a$ symbols and commands. Although not shown in FIG 1, electronic device 12 may also include other components as well, such as a display, memory, input and output connectors, etc.

[0022] An enlarged view of an example of apparatus 10 to use in electronic device 12 is shown in FIG. 2. An example of an exploded view of apparatus 10 to use in electronic device 12 is shown in FIG. 3. As can be seen in FIG. 2, apparatus 10 also includes a bracket 34 to secure first side 28 of touch pad 14 to housing 20 adjacent edge 16, Bracket 34 includes a portion 36 that extends across and is attached to back surface 38 of touch pad 14, Bracket 34 also includes mounting flanges 40, 42. and 44 to secure bracket 34 to back surface 46 of housing 20 via fasteners 48, SO. and 52 mat are disposed in openings 54, 56, and 5$ (see FIG. 3) defined by respective mounting flanges 40, 42, and 44 that are received in respective bosses 60, 62, and 64 (see, FIGs. 2 and 3) of housing 20, Housing 20 includes guide pins 66 and 68 that are disposed in respective openings 70 and 72 (see FIG, 3) of respective mounting flanges 40 and 42 to help orient bracket 34 with respect to back surface 46 of housing 20. Bracket 34 creates a hinge that allows respective first and second corners 24 and 26 to move in either a direction toward or away from front surface 30 of housing 20 during selective movement thereof by adjustment mechanism 22, as discussed more fully below. [0023] As can Also be seen in FIG, 2, apparatus 10 may also include a bracket 74 to help secure second side 76 (see FIG. 3) of touch pad 14 to housing 20 adjacent edge 16, As can be seen in FIGs, 2 and 3, bracket 74 includes a plurality of openings 7$, 80, 82, and 84 through which respective fasteners 86, 88, 90, and 92 are disposed into respective bosses 94.96, 98, and 100. This helps to secure bracket 74 to back .surface 46 of housing 20, as shown in FIG. 2. Housing 20 includes guide pins 102 and 104 that are disposed in respective openings 106 and 108 (see FIG, 3) of bracket 74 to help orient bracket 74 which respect to back surface 46 of housing 20,

[0024] As can be seen in FIGs. 2 and 3, apparatus 10 may include a pair of biasing members 110 and 112 that are attached at respective ends 114 and 116 to back surface 38 of touch pad 14. In the examples shown in FIGs. 2 and 3, biasing members 110 and 112 include respective leaf springs 118 and 120 with respective ends 122 and 124 that are angled toward bracket 74 so as to be in contact with bracket 74 when bracket 74 is secured to back surface 46 of bousing 20, as shown in FIG..2. This contact of ends 122 and 124 with bracket 74 compresses respective leaf springs 118 and 120 of respective biasing members 110 and 112 which generally urges touch pad 14 toward front surface 30 of housing 20.

[0025] An example of a step 126 between first corner 24 of touch pad 14 and adjacent edge 16 of housing 20 of electronic device 12 is shown in FIG.4, An example of a cross-sectional view of step 126 between first corner 24 of touch pad 14and an adjacent edge 16 of housing 20 of electronic device 12 taken along line 5-5 of FIG.4 is shown in FIG> 5. As can be seen in FIGs. 4 and 5, adjustment mechanism 22 includes a first ramp 128 on back surface 46 of housing 20 adjacent edge 16 of opening 18 defined by housing 20. First ramp 128 has an incline that increases in a direction away from first corner 24 of touch pad 14. As can also be seen in FIGs. 4 and 5, adjustment mechanism 22 includes a first shim 130 having a first end 132 stideably coup!ed to First map 128 and a second end 134 slideably coupled to touch pad 14. As can additionally be seen in FIGs. 4 and 5, in this example, adjustment mechanism 22 abo includes a first holder plate 136 on back surface 38 of touch pad 14 in which second end 134 of first shim BO is slideably disposed, hi the example shown;in FIGs. 4 and 5, first shim 130 includes a first biasing member 138 in the form of a leaf spring.

[0026] Step 126 may be minimized by movement of first shim 130 along first ramp 128 in a first direction, indicated by arrow 140 in FIGs. 4 and 5, which causes first corner 24 of touch pad 14 to move toward from surface 30 of housing 20 of electronic device 12, as indicated by arrow 142. This movement of first shim 130 along first, ramp 128 in first direction 140 and first corner 24 toward front surface 30 of housing 20 in the direction of arrow 142 eventually results in first comer 24 of touch pad 14 and adjacent edge 16 of housing 20 of electronic device 12 becoming substantially flush, as shown in FIGs.6 and 7. As can be seen in FIGs. 6 and 7, first ramp 128 includes a first stop 144 that limits movement of first, shim 130 in first direction 140.

[0027] As can also be seen in FIGs. 6 and 7. first shim 130 may also be moved along first ramp 128 in a second direction, indicated by arrow 146, which causes first coi ner 24 of touch pad 14 to move away from front surface 30 of housing 20 in the direction of arrow 148. These movements may be helpful to address a different type of step between first corner 24 of touch pad 14 and adjacent edge 16 of housing 20 of electronic device 12 of the type illustrated and discussed below with respect to second comer 26. First ramp 128 also includes a second stop

150 that limits movement of first shim 130 in second direction 146.

[0028] An example of a step 152 between second corner 26 of touch pad 14 and adjacent edge 16 of housing 20 of electronic device 12 is shown in FIG. 8. An example of a cross-sectionai view of siep 152 between second corner 26 of touch pad .14 and an adjacent edge 16 of boosing 20 of electronic device 12 taken along line 9-9 ofFIG. 8 is shown in FIG. 9. As can be seen is FIGs, 8 and 9, adjustment mechanism 22 includes a second ramp 154 on back surface 46 of housing 20 adjacent edge 16 of opening I 8 defined by housing 20. Second ramp 154 has an incline thai increases in a direction away from second comer 26 of touch pad 14. As can also be seen in FIGs. 8 and 9, adjustment mechanism 22 includes a second shim 156 having a first end 153 slideabiy coupled to second ramp 154 and a second end 160 siideabiy coupled to touch pad 14. As can additionally be seen in FIGs. 8 and 9, in this example, adjustment mechanism 22 also includes a second holder plate 162 on back surface 38 of touch pad 14 in which second end 160 of second shim i 56 is siideabiy disposed, in the example shown in FIGs. 8 and 9, second shim 156 includes a second biasing member 164 m the form of a leaf spring.

[0029] Step 152 may be minimized by movement of second shim 156 along second ramp 154 in a thud direction, indicated by arrow 166 in F1Gs 8 and 9, which causes second corner 26 of touch pad 14 to move away from front surface 30 of housing 20 of electronic device 12, as indicated by arrow 168. This movement of second shim 156 along second ramp 154 in third direction 166 and second corner 26 away from ftont surface 30 of housing 20 in the direction of arrow 168 eventually results in second corner 26 of touch pad 14 and adjacent edge 16 of housing 20 of electronic device 12 becoming substantially flush , as shown in FIGs. 10 and 11. As can be seen in FIGs. 10 and 11, second ramp 154 includes a third stop 170 mat limits movement of second shim 156 in third direction 166.

[0030] As can also be seen in FIGs. 10 and I I, second shim 156 may also be moved along second ramp 154 in a fourth direction, indicated by arrow 172, which causes second comer 26 of touch pad 14 to move toward front surface 30 of housing 20 in the direction of arrow 174. These movements may be helpful to address a different type of step between second comer 26 of touch pad 14 and adjacent edge 16 of housing 20 of electronic device 12 of the type illustrated and discussed above with respect to first comer 24. Second ramp 154 also includes a fourth stop } 76 that limits movement of second shim 156 in fourth direction 172.

[0031] Examples of art enlarged view of adjustment mechanism 22 are shown in FIGs. 12 and 13. As can be seen in FIGs. 12 and 13, first end 132 of first shim 130 includes a clip ! 78 that slideable couples to first ramp !28 fo permit first end 132 of first shim 132 to move along first ramp 128 anywhere between the two positions shown in FIGs. 12 and 13. First end 158 of second shim 156 also includes a clip 180 (see, e.g. ( FIGs. 8 and 10) that slideably couples to second ramp 154 to permit first end J 58 of second shim ! 56 to move along second ramp 154 anywhere between the two positions shown, for example, in FIGs. 8 and 10.

[0032] Referring again to FIGs. 12 and i 3, tint solder plate 136 includes a raised portion 182 that defines a cavity 184 between touch pad 14 and raised portion 182 into which second end 134 of first shim 130 is stideably disposed to slideably coupie first shim 130 to touch pad 14 to permit second end 134 of first shim 130 to move anywhere between the two positions shown in FIGs. 12 and 13. Second holder plate 162 also includes a raised portion 186 (see, e.g., FIGs. 8 and 10) into which second end 160 of second shim 156 is slideably disposed to slideably couple second shim 156 to touch pad 14 to permit secot-d end 160 of second shim 156 to move anywhere between the two positions shown, for example, in FIGs, 8 and 10.

[0033] An example of a method 190 to use in an electronic device is shown in FIG. 14. As can be seen in FIG. 14, method 190 starts 192 by installing a touch pad adjacent an edge of an opening defined by a housing of the electronic device, as indicated by block 194, and securing a first side of the touch pad to the housing adjacent me edge, as indicated by block 196. Method 190 continues by actuating an adjustment mechanism to selectively move a first corner and a second comer of the touch pad that are opposite the first side in either a direction toward or away from a front surface of the housing so that the first and second comers are substantially flush with the adjacent edge, as indicated by block 198. Method 190 may then end 200.

[0034] Although several drawings have been described and illustrated in detail, it is to be understood that the same are intended by way of illustration and example. These examples are not intended to be exhaustive or to be limited to the precise form disclosed. Modifications and variations may well be apparent.

[0035] Additionally, reference to an element in the singular is not intended to mean one, unless explicitly so stated. Furthermore, unless specifically stated, any method elements are not limited to the sequence or order described and illustrated. Moreover, no element or component is intended to be dedicated to the public regardless of whether the element or component is explicitly recited in the following claims.
