Protective case having elastically deformable air chambers for impact reduction

摘要

The present invention is to provide a. protective case having elastically deformable air chambers for impact reduction, which is made of an elastically deformable material and includes at least four lateral walls and at least four outer curved walls each connecting adjacent lateral wails, such that the outer curved wails and the lateral walls jointly form and enclose a receiving space. When a portable electronic device is received in the receiving space, the inner sides of the lateral walls lie against the four lateral sides of the periphery of the portable electronic device respectively. Meanwhile, the outer curved walls correspond in position to the four corners of the portable electronic device respectively, but the inner sides of the outer curved walls are not in contact with the portable electronic device, so as to form the air chambers between the outer curved walls and the portable electronic device respectively.

主权项

1. A protective case having elastically deformable air chambers for impact reduction, the protective case being applicable to a portable electronic device and made of an elastically deformable material, the protective case comprising:
four lateral walls; four outer curved walls each connecting two adjacent said lateral walls such that the lateral walls and the outer curved walls jointly form and enclose a receiving space, wherein when the portable electronic device is received in the receiving space, inner sides of the lateral walls lie against four lateral sides of a periphery of the portable electronic device respectively, the outer curved walls correspond in position to four corners of the portable electronic device respectively, with inner sides of the outer curved walls not being in contact with the portable electronic device such that a buffer gap is formed between each said outer curved wall and the portable electronic device, and a first spacing defined between a tangent line tangent to two adjacent said outer curved walls and the portable electronic device is greater than a second spacing defined between an extension line extending along an outer side of any said lateral wall and the portable electronic device; and four inner curved walls each having two ends respectively and sealingly connected to inner sides of two ends of a corresponding said outer curved wall that are respectively connected to two adjacent said lateral walls, such that said buffer gap is formed between each said inner curved wall and the corresponding outer curved wall.
