Portable electronic device protective cover

[0002] The present invention relates to a portable electronic device protective cover and, more particularly, to such a protective cover, which fits perfectly the shape of the portable electronic device to be protected.

[0003] FIG. 9 illustrates a remote controller protective sheath 1 constructed according to U.S. patent application Ser. No. 09/568,851, which was filed by the present inventor. This remote controller protective sheath 1 comprises a peripheral strip 11, a bottom cloth panel 13, and a transparent top panel 12. The peripheral strip 11, the bottom cloth panel 13 and the transparent top panel 12 are respectively attached to a frame mold, and then fastened together by a high-frequency heat sealing apparatus. The remote controller protective sheath 1 has an opening 14 disposed at one end between the two ends of the peripheral strip 11. The top panel 12 has an extension flap 121. After insertion of the remote controller 2 through the opening 14 into the inside of the protective sheath 1, the extension flap 121 is turned back and inserted into the opening 14 to close the opening 14. When turned back and inserted into the opening 14, two gaps 122 exist at two sides between the extension flap 121 and the two ends of the peripheral strip 11, and outside dust may pass through the gaps 122 into the inside of the protective sheath 1 to contaminate the remote controller 2.

[0004] The present invention has been accomplished to provide a portable electronic device protective cover, which eliminates the aforesaid problem. According to one aspect of the present invention, the protective cover comprises a loop-like plastic peripheral strip fitting the periphery of the electronic device to be protected, the loop-like peripheral strip having an insertion slot through which the electronic device to be protected is inserted into the inside of the portable electronic device protective cover, a transparent plastic top panel peripherally sealed to the top side of the loop-like peripheral strip by a high-frequency heat sealing apparatus, and a transparent plastic bottom panel peripherally sealed to the bottom side of the loop-like peripheral strip by a high-frequency heat sealing apparatus. According to another aspect of the present invention, hook and loop materials are provided at the loop-like peripheral strip, and adapted to close/open the insertion slot.

[0014] Referring to FIGS. From 1 through 3, a protective cover 3 is made subject to a mold 4, which is an open frame fitting the height and width of the remote-controller 2 to be protected. The protective cover 3 comprises a peripheral strip 31, a transparent top panel 32, and a transparent bottom panel 33. The peripheral strip 31, the transparent top panel 32, and the transparent bottom panel 33 are respectively cut from transparent sheet material, for example, PVC (polyvinyl chloride) sheet material. The two ends of the peripheral strip 31 are sealed together, forming a loop. An insertion slot 311 is formed in one end of the loop-like peripheral strip 31. The loop-like peripheral strip 31 fits the inner diameter of the mold 4. After preparation, the loop-like peripheral strip 31 is put in the mold 4 and closely attached to the inside wall of the mold 4, and then the mold 4 with the loop-like peripheral strip 31 are put on the bottom panel 33 in a high-frequency heat sealing machine, and then the border of the bottom panel 33 is heat-sealed to the border of the bottom side of the loop-like peripheral strip 31 by the high-frequency heat sealing machine, and then the top panel 32 is covered on the mold 4 over the border of the top side of the loop-like peripheral strip 31 and heat-sealed to the border of the top side of the top side of the loop-like peripheral strip 31 by the high-frequency heat sealing machine. During sealing, the protruding portions of the loop-like peripheral strip 31, the top panel 32 and the bottom panel 33 outside the seal area are simultaneously cut away by the top and bottom cutting edges of the mold 4. After sealing, the desired protective cover 3 is obtained, which fits the shape of the remote controller 2. Through the insertion slot 311, the remote controller 2 is inserted into the inside of the protective cover 3.

[0015] Referring to FIGS. 4 and 5, hook and loop materials 34 are provided at one end of the peripheral strip 31 of the protective cover 3, and adapted to control the entrance of the insertion slot 311.

[0016] Referring to FIG. 6, the protective cover 5 fits the shape of a cellular telephone 6, comprising a loop-like peripheral strip 51, a transparent top panel 52 peripherally sealed to the periphery of the top side of the loop-like peripheral strip 51, and a transparent bottom panel 53 peripherally sealed to the periphery of the bottom side of the loop-like peripheral strip 51, an insertion slot 511 in the loop-like peripheral strip 51 through which the cellular telephone 6 is inserted into the inside of the protective cover 5, a fastener 55 fixedly provided at the bottom panel 53 for fastening, and holes 54 formed in the loop-like peripheral strip 51 corresponding to the antenna and power switch of the cellular telephone 6.

[0017] Referring to FIG. 7, the protective cover 7 fits the shape of a PDA (personal digital assistant) 8, comprising a loop-like peripheral strip 71, a transparent top panel 72 peripherally sealed to the periphery of the top side of the loop-like peripheral strip 71, and a transparent bottom panel 73 peripherally sealed to the periphery of the bottom side of the loop-like peripheral strip 71, an insertion slot 711 in the loop-like peripheral strip 71 through which the PDA 8 is inserted into the inside of the protective cover 7, and a hole 74 formed in the loop-like peripheral strip 71 corresponding to the power switch 81 of the PDA 8.

[0018] Referring to FIG. 8, the protective cover 9 fits the shape of an electric steel rolling door remote controller 21, comprising a loop-like peripheral strip 91, a transparent top panel 92 peripherally sealed to the periphery of the top side of the loop-like peripheral strip 91, and a transparent bottom panel 93 peripherally sealed to the periphery of the bottom side of the loop-like peripheral strip 91, and an insertion slot 911 in the loop-like peripheral strip 91 through which the electric steel rolling door remote controller 21 is inserted into the inside of the protective cover 9.

[0019] A prototype of portable electronic device protective cover has been constructed with the features of FIGS. 1˜8. The portable electronic device protective cover functions smoothly to provide all of the features discussed earlier.

[0020] Although a particular embodiment of the invention has been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
