Cover with elastic portion for bar-type portable terminal device

Abstract

Provided is a bar-type portable terminal device cover having an elastic portion, which is capable of achieving, due to the provision of an elastic portion, convenient detachability of the cover while providing a streamlined configuration to allow complete protective surrounding of device corners by corner portions of the cover to thereby exclude the formation of cut grooves responsible for contamination risk, and which is also capable of significantly improving quality of the product due to having improved device protective performance and elegant external appearance. For this purpose, the bar-type portable terminal device cover is configured to have a structure surrounding rear and lateral sides of a device and comprises a main body in contact with a rear side of a device, side walls for surrounding both lateral sides of the device, an elastic portion provided between the main body and the both side walls or at the center of the main body, and rounded corner portions for surrounding corners of the device formed on the side walls and extending at both ends of the lengthwise direction, wherein the elastic portion is formed inward such that it can be flexibly bent from the main body.

       9 . The cover according to  claim 3 , wherein the elastic portion is a “]”-shaped groove with inclined portions relative to an inner surface of the main body. 
   
   
       10 . The cover according to  claim 1 , wherein the elastic portion comprises a inwardly formed groove continuously extending from one end of the main body to another end of the main body. 
   
   
       11 . The cover according to  claim 10 , wherein the elastic portion is formed inward at an inner surface of the main body. 
   
   
       12 . The cover according to  claim 11 , wherein the elastic portion is formed inward at both an inner and an outer surface of the main body. 
   
   
       13 . A cover of a bar-type portable terminal device having an elastic portion, which is configured to have a structure surrounding rear and lateral sides of a device and which comprises:
 a main body in contact with a rear side of a device,   side walls for surrounding both lateral sides of the device,   an elastic portion provided between the main body and the both side walls or at the center of the main body, and   rounded corner portions for surrounding corners of the device formed on the side walls and extending at both ends of the lengthwise direction,   wherein the elastic portion is formed inward such that it can be flexibly bent from the main body and is formed to have a “]”-shaped or “V”-shaped groove which is formed on either an inner surface or both of an inner surface and an outer surface of elastic portion.   
   
   
       14 . A cover of a bar-type portable terminal device having an elastic portion, which is configured to have a structure surrounding rear and lateral sides of a device and which comprises:
