Protective case with embedded elastic cushion plates

Abstract

The present invention is to provide a protective case embedded with elastic cushion plates and applicable to a portable electronic device (e.g., a smartphone, tablet PC, or e-book reader), which includes a case body made of a first elastic material (e.g., thermoplastic polyurethane) and having four sidewalls and four curved walls each connecting two adjacent sidewalls to jointly form a receiving space, and four elastic cushion plates made of a second elastic material (e.g., silicone) whose hardness is less than that of the first elastic material. Each curved wall is embedded with the elastic cushion plate. Thus, when the portable electronic device is fitted into the receiving space through an opening of the protective case, four corners of the portable electronic device lie against the elastic cushion plates respectively, so as to ensure that the elastic cushion plate can greatly reduces impact of an external force applied to the corner.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a protective case, more particularly to a protective case embedded with elastic cushion plates and applicable to a portable electronic device (e.g., a smartphone, tablet PC, or e-book reader), which includes a case body made of a first elastic material (e.g., thermoplastic polyurethane) and having four sidewalls and four curved walls each connecting two adjacent sidewalls to jointly form a receiving space, and four elastic cushion plates made of a second elastic material (e.g., silicone) whose hardness is less than that of the first elastic material. Each curved wall is embedded with the elastic cushion plate. Thus, when the portable electronic device is fitted into the receiving space through an opening of the protective case, the inner side of each sidewall lies against each side of the portable electronic device, and each curved wall corresponds to each corner of the portable electronic device, such that the four corner...

Benefits of technology

[0008]The present invention provides a protective case embedded with elastic cushion plates and applicable to a portable electronic device (e.g., a smartphone, tablet PC, or e-book reader). The protective case includes a case body and four elastic cushion plates. The case body is made of a first elastic material (e.g., thermoplastic polyurethane), at least includes four sidewalls and four curved walls, and is embedded with the four elastic cushion plates. Each curved wall connects two adjacent sidewalls such that a receiving space is jointly formed and surrounded by the curved walls and the sidewalls. The rear ends of the curved walls and of the sidewalls are joined together to form a rear wall at the rear end of the case body. The front end of the case body forms an opening. The opening is in communication with the receiving space and has a diameter smaller than the inner diameter of the receiving space. The inner side of each curved wall is concavely provided with an embedment groove. Each two adjacent curved walls jointly define a tangent line tangent to the outer peripheries of both curved walls. The sidewall between each two adjacent curved walls has an outer side defining an extension line. The elastic cushion plates are made of a second elastic material (e.g., silicone) whose hardness is less than that of the first elastic material. Each elastic cushion plate matches a corresponding one of the embedment grooves in configuration. Each elastic cushion plate is securely fitted in the corresponding embedment

Problems solved by technology

In consequence, portable electronic devices have shown a decline in production costs and been made increasingly thinner and lighter.

Due to their powerful functions and wide application, the aforesaid portable electronic devices are used more and more frequently by their users and hence stand a progressively greater chance of being worn or scratched by pointed objects or damaged by the impact of an inadvertent drop or collision.

Should any of the foregoing incidents happen to a portable electronic device, a minor damage (e.g., scratches on the screen or on the main body of the portable electronic device) may impair th
