Case having a shock absorbing structure for electronic devices
The present invention relates to a case having a shock absorbing structure for an electronic device which includes a protective shell, a side enclosure frame, and a shock absorbing block. The shock absorbing block is constructed to have a plurality of recesses formed on the side wall of the protective shell such that adjacent recesses are separated by a partition. The recesses are rectangular and the plurality of recesses has a continuous unitary construction along lower part of the four sides of the protective shell. In addition, the side enclosure frame includes an upper protrusion and a lower protrusion, formed on an inner-facing surface of the side enclosure frame. The side wall of the protective shell includes an upper cavity and a lower cavity. The upper protrusion fits within the upper cavity and the lower Protrusion fits within the lower cavity.
1. A case having a shock absorbing structure for an electronic device, comprising:
a bottom wall to cover a bottom portion of the electronic device;
four side walls extending perpendicularly from the bottom wall to cover four side portions of the electronic device wherein two adjacent walls form a rounded corner; and
a shock absorbing recess formed longitudinally within an inner curved portion of the rounded corner in a direction substantially perpendicular to the bottom wall, wherein the shock absorbing recess does not make two outer-facing surfaces of the adjacent side walls being outwardly bulged,
wherein the shock absorbing recess comprises a recess opening which is substantially symmetrical with respect to a middle vertical line of the rounded corner,
wherein the case is made of a soft material.
2. The case of claim 1 , wherein the shock absorbing recess is spaced apart from the bottom wall.
3. The case of claim 1 , wherein the case is made of a thermoplastic polyurethane.
4. The case of claim 1 , wherein the recess opening includes rounded inlets.
5. The case of claim 1 , wherein the shock absorbing recess tapers toward to a recess bottom.
6. The case of claim 5 , wherein the recess bottom is rounded.
7. The case claim 5 , wherein the recess bottom is flat.
8. The case of claim 5 , wherein the two sides of the shock absorbing recess are concavely curved toward the recess bottom.
9. The case of claim 5 , wherein the two sides of the shock absorbing recess convexly taper and then, passing an inflection point, concavely taper toward the recess bottom.
10. The case of claim 5 , wherein the two sides of the shock absorbing recess concavely taper toward the race bottom wherein the two sides of the shock absorbing recess have a first concave portion and a second concave portion.
11. A case having a shock absorbing structure for an electronic device, comprising:
a bottom wall to cover a bottom portion of the electronic device;
four side walls extending perpendicularly from the bottom wall to cover four side portions of the electronic device wherein two accent walls fits a rounded corner; and
a shock absorbing recess formed longitudinally within an inner curved portion of the rounded corner in a direction substantially perpendicular to the bottom wall, wherein the shock absorbing recess does not make two outer-facing surfaces of the adjacent side walls being outwardly bulged,
wherein the shock absorbing recess is formed at about a center of the rounded corner,
wherein the shock absorbing recess is spaced apart from top and bottom of the rounded corner,
wherein the case is made of a soft material.
12. The case of claim 11 , wherein the shock absorbing recess has two sides which are symmetrical to each other.
13. The case of claim 11 , wherein the case is made of a thermoplastic polyurethane.
14. The case of claim 11 , wherein the recess opening includes rounded inlets.
15. The case of claim 11 , wherein the shock absorbing recess tapers toward to a recess bottom.
16. The case of claim 15 , wherein the recess bottom is rounded.
17. The case of claim 15 , wherein the recess bottom flat.
18. The case of claim 15 , wherein the two sides of the shock absorbing recess are concavely curved toward the recess bottom.
19. The case of claim 15 , wherein the two sides of the shock absorbing recess convexly taper and then, passing an inflection point, concavely taper toward the recess bottom.
20. The case of claim 15 , wherein the two sides of the shock absorbing recess concavely taper toward the recess bottom wherein the two sides of the shock absorbing recess have a first concave portion and a second concave portion.
