DETAILED DESCRIPTION

[0038] The present principles are directed to an electronic apparatus and an associated disassembly release tool designed to quickly and safely disassemble the electronic apparatus.

[0039] FIG. 2 shows a perspective view of the vertically oriented electronic device 200 having a top 210, a front wall 208, a rear wall 206, side walls 204, and a base 205, in accordance with an embodiment of the present principles.

[0040] FIG. 3 shows the three principal pieces of the vertically oriented electronic device 200, in accordance with an embodiment of the present principles. The three pieces are the case bottom piece 213, the case top front piece 211, and the case top back piece 212.

[0041] FIG. 4 is a perspective view of a retention clip 214, which can be metal, that is utilized to engage and secure the case bottom piece 213 to the case top front piece 211 and/or the case top back piece 212, in accordance with an embodiment of the present principles.

[0042] FIG. 5 shows how the case top front piece 211 is slid back onto case top back piece 212 of the electronic device 200, and then up into retaining features in order lock the two together such that internal electronic components can be housed therein when the assembly is finalized, in accordance with an embodiment of the present principles. FIGS. 6-8 show the specific engagement mechanism in which a protruding ledge 216 extends inwardly from the interior surface of one of the vertical walls of one of the pieces, in accordance with an embodiment of the present principles. The protruding ledge 216 includes protrusions 215 that engage protrusion receiving openings 217 on the case front piece 211. The protrusion receiving openings 217 are generally horizontal ledges that have upstanding peripheral walls to make a slot that can receive the protrusions 215. The slots can be oversized in the dimension that is perpendicular from the interior wall from which the ledge extends or along its long lateral axis. The slot can be narrow along the dimension parallel to the wall or along the ledge's short lateral axis to snuggly fix the protrusions 215. The protruding ledge 216, the protrusions 215, and the protrusion receiving openings 217 form a screwless engagement structure.

[0043] FIGS. 9 and 10 show further perspective views of the retaining features that are used to engage the case top front piece 211 with the case top back piece 212, in accordance with an embodiment of the present principles. FIG. 9 shows ribs 218 that are positioned above the protrusion receiving openings 217 and also extend inwardly from the interior surface of one of the vertical walls of the front piece 211. The ribs 218 would interfere with the case rear retention feature if an assembly start position is attempted that is too low. FIG. 10 shows that a chamfer 299 guides the case top 210 to an acceptable start location. Rib 218 prevents case front from starting in too low of a position by preventing excessive case travel which can damage components.

[0044] FIG. 11 is a disassembled perspective view of the vertically oriented electronic device 200 showing the interior walls of the front piece 211 and the case top back piece 212 of the electronic device 200, in accordance with an embodiment of the present principles. The retention protrusions 291, the retention openings 292, and over travel prevention portions 293 are shown in FIG. 11.

[0045] It should be noted that the device 200 can include electronic components such as circuit boards, hard drives, antennae, etc. and that the electronic components can be connected to a panel jack. The panel jack can be on the rear wall 206 or can be a part of the rear wall. The rear wall 206 can be part of the case top back piece 212 in which some of the lower rectangular features on the piece 212 in FIG. 11 can represent a panel jack.

[0046] FIG. 12 is a bottom perspective view of the vertically oriented electronic device 200 in which the case bottom piece 213 is not attached, in accordance with an embodiment of the present principles.

[0047] FIGS. 13-15 are various views of the metal retention clips 214, in accordance with an embodiment of the present principles. The views show that the front piece 211 and the case top back piece 212 can be attached to one another and can then be attached to the case bottom piece 213 using the metal retention clips 214. The metal retention clips 214 are retained by features on the case top front piece 211 and the case top back piece 212. The clips 214 are generally V-shaped in which there is an anchor portion 220 which is one side of the V-shape. The anchor portion 220 can have a rectangular planar shape and have an aperture 277 that fits into an anchor base 221 of the case top front piece 211 and the case top back piece 212. FIG. 15 shows how the aperture 277 of anchor portion 220 engages a protrusion 221A in the anchor base 221 such that an inward pointing ledge at the top of the anchor portion 220 grasps a top portion of the anchor base 221 and the bottom inner wedge grasps the bottom portion of the anchor base 221 to the secure the retention clip 214. This permits the locking portion 219 of the clip 214, which is the other side of the V-shape, to engage with features of the bottom piece 213 to close or assemble the electronic device 200. In particular, the top of the locking portion 219 can have a horizontal ledge that extends inwardly to contact a bottom surface of the clip engaging features 222 and the locking portion 219 can further have an upward extension at the edge of the ledge to engage an edge of the bottom surface of the feature 222 as the outward spring force of spring 214 cause the locking portion to move outward to engage the feature 222 as shown in FIG. 18. Although a V-shape is shown, a U-shape could be employed as well and both sides of the V or U-shape part can have different heights.

[0048] FIG. 16 is a perspective view of the case bottom piece 213 which shows the base 205 and clip engaging features 222 that extend vertically upward from the bottom piece 213, in accordance with an embodiment of the present principles. The clip engaging features 222 are designed to engage the locking portion 219 of the clips 214 on the case front 211 and the case top back piece 212. A screwless clip and spring mechanism 288 is formed from the clips 214 and clip engaging features.

[0049] FIGS. 17 and 18 are perspective views showing how the case bottom piece 213 engages the case top front piece 211 and the case top back piece 212, in accordance with an embodiment of the present principles. Release finger 301 pushes locking portion inward to disengage the locking portion 219 as it enters aperture 223

[0050] FIG. 19 is a bottom perspective view of the vertically oriented electronic device 200, in accordance with an embodiment of the present principles.

[0051] FIG. 20 is a view of a release fixture 300, in accordance with an embodiment of the present principles. FIGS. 19 and 20 show release aperture 223 in base 205 which permits a release finger 301 on a base of a release fixture 300 to enter the release aperture 223 to push the locking portion 219 inward toward the anchor portion 220 to remove the top portion of the locking portion 219 off of the engaging feature 222. This can be understood also with reference to FIG. 18 in which the release finger 301 (not shown in FIG. 301) will contact the outer edge of the locking portion 219 move the locking portion 219 away from engaging feature 222.

[0052] FIG. 21 is a flow diagram showing an exemplary method 2100 for assembling an electronic device having a case bottom piece, a case top front piece, and a case top back piece, in accordance with an embodiment of the present principles. At step 2110, attach the case top front piece 211 to the case top back piece 212 to form a top structure 210 using a screwless engagement structure 977. At step 2120, attach the top structure 210 to the case bottom piece 213 using a plurality of screwless clip and spring mechanisms 288.

[0053] FIG. 22 is a flow diagram showing an exemplary method 2200 for disassembling an electronic device having a case bottom piece, a case top front piece, and a case top back piece, in accordance with an embodiment of the present principles. The method 2200 is applied to an assembled condition, wherein the case top front piece is attached to the case top back piece 212 to form a top structure 210 using a screwless engagement structure 977, and the top structure is attached to the case bottom piece using a plurality of screwless clip and spring mechanisms 288. At step 2210, move a release fixture 300 with release fingers 301 vertically upward toward a bottom of the electronic device to simultaneously disengage a locking portion 219 of each of the plurality of screwless clip and spring mechanisms 288 to allow the case top front piece 211 and the case top back piece 212 to be removed upward from the case bottom piece 213. At step 2220, slide the case top front piece 211 down with respect to the case top back piece 212 to disengage the screwless engagement structure 977 and separate the case top front piece 211 from the case top back piece 212 such that electronic components included within the outer casing can be accessed.

[0054] The electronic device 200 can be a set-top box or the like and can be vertically oriented such that the height of the device is higher than the width of the front vertical surface and/or the rear vertical surface and/or the lateral depth. The lateral cross section can be a quadrilateral shape in which the front and back are parallel and the side surfaces are not parallel to one another. The device can be designed such that the release fixture and release fingers move vertically upward toward the bottom of the device to simultaneously disengage the plurality of the locking portions to allow the case top front piece 211 and the case top back piece 212 to be remove upward from the case bottom piece 213. The case top front piece 211 and the case top back piece 212 can then further be detached from one another by moving the case top in a motion oppose to that shown in FIG. 5 to attach the two pieces (case top front piece 211 and case top back piece 212). With the two pieces 211 and 212 attached, the assembly can be reassembled or assembled by aligning the clip engaging features 222 with the clip 214 when the release fixture is removed or not present.

[0055] Thus, a method of retaining three parts together without screws to form a complete casing that is designed to enable a release tool to access the interior. More particularly, the only access to non-destructively open the casing can be from a bottom facing surface. This ensures that no access holes are observed on viewable appearance surfaces, which are generally the vertical surfaces and the top. The focus of the disclosure is for casings having a given shape that is a vertically oriented tall structure which would not mold easily as a two piece design and meet consumer demand. However, with such a form, a three piece design is disclosed that has release latches for front and back case pieces that do not require unsightly access holes on the vertical viewable surfaces and top, and advantageously meet consumer preference and include pieces that mold more conveniently.
