## Abstract

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.

## Claims

### Claim 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 from the bottom wall to cover four side portions of the electronic device wherein two adjacent side walls form a rounded corner; and
a shock absorbing recess formed at an inner curved portion of the rounded corner, wherein the shock absorbing recess is formed longitudinally on the inner curved portion of the rounded corner in a direction substantially perpendicular to the bottom wall,
wherein the shock absorbing recess tapers toward to a recess bottom,
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 formed within the inner curved portion of the rounded corner of the case corresponding to a rounded corner of an electronic device,
wherein the recess opening includes rounded inlets,
wherein the case is made of a soft material.

### Claim 2 (depends on 1)

The case of claim 1, wherein the shock absorbing recess is concavely curved toward the recess bottom.

### Claim 3 (depends on 1)

The case of claim 1, wherein the shock absorbing recess convexly tapers and then, passing an inflection point, concavely tapers toward the recess bottom.

### Claim 4 (depends on 1)

The case of claim 1, wherein the shock absorbing recess concavely tapers toward the recess bottom wherein the shock absorbing recess has a first concave portion and a second concave portion.

### Claim 5

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 from the bottom wall to cover four side portions of the electronic device wherein two adjacent side walls form a rounded corner; and
a shock absorbing recess formed at an inner curved portion of the rounded corner, wherein the shock absorbing recess is formed longitudinally on the inner curved portion of the rounded corner in a direction substantially perpendicular to the bottom wall,
wherein the shock absorbing recess tapers toward to a recess bottom,
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 has two sides which are symmetrical to each other and inlets of the two sides are rounded,
wherein the shock absorbing recess comprises a recess opening is formed within the inner curved portion of the corner of the case corresponding to a rounded corner of the electronic device,
wherein the recess opening includes the rounded inlets,
wherein the case is made of a soft material.

### Claim 6 (depends on 5)

The case of claim 5, wherein the two sides of the shock absorbing recess are concavely curved toward the recess bottom.

### Claim 7 (depends on 5)

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.

### Claim 8 (depends on 5)

The case of claim 5, 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.
