protecting mobile phones against abrasion and drop, preventing the
product external appearance, use performance and service life from
deteriorating.
[0005] Among numerous protecting methods and protecting
apparatuses, there is a fashion and popular method to protect the
mobile by covering the periphery of the mobile phone with a hard or
soft sleeve, particularly the side edges and the angles (of the
mobile) that are most likely to be scratched can be protected. The
sleeves are mostly integrally-formed hard or soft rubber products,
so that they cannot abut against the mobile phone to be protected
closely, adversely affecting the appearance of the mobile
phone.
[0006] The present invention has arisen to mitigate and/or obviate
the afore-described disadvantages.

[0032] Referring to FIGS. 1-10, a protecting case in accordance
with a preferred embodiment of the present invention comprises an
upper protecting element 1 and a lower protecting element 2. The
upper protecting element 1 is in the form of a hollow frame and
includes a rectangular upper engaging portion 11 and a stepped
frame body 13 around a top thereof in such a manner that a top
opening 111 is smaller than a bottom opening 112. Adjacent to the
bottom opening 112 is annularly provided a groove 12 around an
inner periphery of the upper protecting element 1. The upper
protecting element 1 is engaged on a to-be-protected product 3
through the bottom opening 112 in such a manner that the upper
engaging portion 11 can be closely fitted on the top outer
periphery of the to-be-protected product 3. The stepped frame body
13 of the upper protecting element 1 is formed with an arc surface
to be fitted on an arc surface formed on a top circumference of an
upper portion 31 of the to-be-protected product 3.
[0033] The lower protecting element 2 is in the form of a hollow

element 2 can also be formed as a closed solid structure 223, so
that the lower protecting element 2 serves as a bottom cover to be
engaged with the upper protecting element 1. In order to make the
protecting case of the present invention more beautiful, the upper
engaging portion 11 and the lower engaging portion 22 both have an
arc outer surface. The upper and the lower protecting elements 1, 2
are engaged to each other through the groove 12 and the rib 21 and
closely fitted on the to-be-protected product 3 to form the
integral structure. By such arrangements, besides the side edges
and the angles of the to-be-protected product 3, the protecting
case in the present embodiment of the present invention can also
protect the whole bottom surface of the to-be-protected product 3.
Furthermore, other uncovered portion can also be protected by the
upper protecting element 1 and the lower protecting element 2
against damage, scratch or wear.
[0036] The upper and the lower protecting elements 1, 2 of the
protecting case of the present invention can be both made of hard
rubber or metal. In addition, the upper protecting element 1 can be
further formed with at least one key hole 113 to be aligned with
the keys 33 on the to-be-protected product 3, increasing the use
convenience.
[0037] In addition, the top outer edge of the upper protecting
element 1 takes the form of a chamfered edge 14, as shown in FIGS.
8 and 9, a right-angle edge 15 as shown in FIG. 12 or a rounded
edge 16 as shown in FIG. 13.
[0038] Likewise, the bottom outer edge of the upper protecting
element 1 takes the form of a chambered edge 17 as shown in FIGS. 8
and 9, a right-angle edge 18 as shown in FIG. 12 or a rounded edge
19 as shown in FIG. 13.
[0039] The to-be-protected product 3 of the present invention is a
mobile phone, preferably an apple iPhone.
[0040] While we have shown and described various embodiments in
accordance with the present invention, it is clear to those skilled
in the art that further embodiments may be made without departing
from the scope of the present invention.
