Document Type and Number:
WIPO Patent Application WO/2012/062114
Kind Code:
A1
Abstract:
A changeable jaw-protecting helmet comprises a helmet shell main body(1), a jaw protector(2) and two pattern plates (3).The jaw protector(2) is provided with two fork handles(2a). The two pattern plates (3) are respectively arranged at the two sides of the helmet shell main body (1). The pattern plates are fastened and connected with the helmet shell main body (1) or the pattern plates (3) are connected with the helmet main body(1) integrally. Each pattern plate (3) is provided with two groove-shaped tracks and is additionally provided with four moving nails. One end of each moving nail is inserted into the four tracks (41, 42) on the two pattern plates respectively. Each fork handle (2a) is respectively connected with the two moving nails (5). The jaw protector (2) drives the moving nail (5) via the fork handle (2a).Each moving nail (5) moves along corresponding track respectively. The jaw protector (2) can change position by restriction of the moving nails (5) and the tracks (41, 42). Compared with the prior art, no track is arranged on the jaw protector (2) so the bending strength of the fork handle (2a) is improved and thus the anti-broking ability of the fork handle (2a) is improved. Besides, potential danger caused by concentrated stress can be effectively eliminated by abandoning the fork handle (2a) chute, in this way, the strength of the jaw protector (2) is improved.
