  • The support portion 100 can couple with the head portion 200 to form the pad 10 as shown in FIG. 3. Because the protrusions 204 of the head portion 200 are formed of softer material than the ring 106 of the support portion 100, when heated, the protrusions 204 of the head portion 200 can soften to a degree such that they can be pressed into the ring 106 such that each of the protrusions 204 encompasses a corresponding portion of the ring 106 bridging the apertures 104. In at least one example, the protrusions 204 of the head portion 200 then cool and solidify, forming around the encompassed portions of the ring 106. The protrusions 204 can be urged and received by the corresponding apertures 104, and correspondingly, the ring 106 can be urged and received by the groove 206. The inner ring 108 is received by the inner groove 208. In at least one example, the support portion 100 does not include an inner ring 108. The head portion 200 can be fused onto the support portion 100 by plastic compounding. In other examples, the head portion 200 can be coupled with the support portion 100 by any suitable means. The support portion 100 has a back side 114 that is a rounded concave surface.
  • When the pad 10 is formed, the outer rim 112 and the outer perimeter portion 212 do not contact one another, as illustrated in FIG. 4. When coupled, the ring 106 separates the support portion 100 and the head portion 200, thereby forming a waist 402. The waist 402 has a smaller diameter than the diameters of the support portion 100 and the head portion 200. The head portion 200 has a second side 214 which is a rounded convex surface. In other examples, the second side 214 can be convex, flat, or irregular in shape.
  • FIG. 5 illustrates a bottom cover 500 of a protective cover for an electronic device.

In other examples, the bottom cover can be substantially circular, ovoid, or any suitable shape that substantially corresponds to the underside of the electronic device. The bottom cover 500 has at least one pad aperture 502 formed therein. In at least one embodiment, the bottom cover 500 has four pad apertures 502 formed therein.
  • The bottom cover 500 has one or more protrusions 504 that extend into the plurality of pad apertures 502 as shown in FIG. 6. In at least one example, the protrusions 504 can be one continuous extension. In other examples, there can be multiple protrusions 504 that extend throughout the pad apertures 502. The protrusions 504 correspond to the waist 402 of the pad 10.
  • As shown in FIG. 7, the pad 10 is inserted through the pad apertures 502. To insert the pad 10, the head portion 100 of the pad 10 (shown in FIG. 4) is inserted through the pad apertures 502 (shown in FIG. 6) of the bottom cover 500. The protrusions 504 of the bottom cover 500 (shown in FIG. 6) can function as receiving surfaces proximate the edge of the pad apertures 502 for the outer rim 112 of the support portion 100. The waist 402 receives the protrusions 504, and the outer rim 112 abuts the protrusions 504, thereby coupling the pad 10 to the bottom cover 500. When being inserted through the pad apertures 502, the head portion 200 deforms against the protrusions 504. When through the pad apertures 502, the head portion 200 reforms wherein the diameter of the head portion 100 is greater than the diameter of the pad apertures 502. As such, the outer perimeter portion 212 of the head portion 200 abuts the protrusions 504, thereby coupling the pad 10 to the bottom cover 500.
  • FIG. 8 illustrates that the protective cover 800 includes a top cover 802 and a bottom cover 500. The top cover 802 corresponds to a top outer surface of the electronic device, which may be for example a laptop device. The top cover 802 is substantially rectangular.
