Sun visor assembly and safety helmet having the same

Abstract

The present disclosure relates to a safety helmet; and, more particularly, to a safety helmet having an extended sun visor capable of preventing light from entering directly into eyes of a helmet wearer. A safety helmet includes a cap having a front opening portion; a sun visor fixed on the cap to be protruded from an upper portion of the front opening portion toward the front; and an extended member located on a front end portion of the sun visor to pivot about the sun visor.

1 . A safety helmet comprising:
 a cap having a front opening portion;   a sun visor fixed on the cap to be protruded from an upper portion of the front opening portion toward the front; and   an extended member located on a front end portion of the sun visor to pivot about the sun visor.   
   
   
       2 . The safety helmet of  claim 1 , wherein the extended member is connected to both lower end sides of the sun visor. 
   
   
       3 . The safety helmet of  claim 1 , wherein the extended member includes a translucent or opaque region. 
   
   
       4 . The safety helmet of  claim 1 , wherein the safety helmet further comprises a pivot controlling mechanism for pivoting the extended member about the sun visor in a step by step. 
   
   
       5 . The safety helmet of  claim 4 , wherein the pivot controlling mechanism includes a protrusion formed on a lower side of the sun visor and more than one grooves, formed on an upper side of the extended member, for accommodating therein the protrusion when the extended member pivots about the sun visor. 
   
   
       6 . The safety helmet of  claim 5 , wherein the pivot controlling mechanism includes a separation preventing portion, formed on a rear end portion of more than one grooves, for supporting the protrusion, and controls a pivot angle of the extended member with respect to the sun visor. 
   
   
       7 . The safety helmet of  claim 4 , wherein the pivot controlling mechanism further includes magnetic members, attached on the lower side of the sun visor and the upper side of the extended member, for connecting with each other. 
   
   
       8 . The safety helmet of  claim 5 , wherein the pivot controlling mechanism further includes an engaged portion formed adjacent to one groove except for a front and a rear groove among said more than one grooves and a stopper accommodated in the engaged portion when the protrusion is accommodated in said one groove. 
   
   
       9 . A sun visor assembly fixed on a front portion of a cap of a safety helmet, the sun visor assembly comprising:
 a sun visor fixed on the cap of the safety helmet having a front opening portion;   an extended member located on a front end portion of the sun visor to pivot about the sun visor.   
   
   
       10 . The sun visor assembly of  claim 9 , wherein the extended member is connected to both lower end sides of the sun visor. 
   
   
       11 . The sun visor assembly of  claim 9 , wherein the extended member has a translucent or opaque region. 
   
   
       12 . The sun visor assembly of  claim 9 , wherein the safety helmet further comprises a pivot controlling mechanism for pivoting the extended member about the sun visor in a step by step. 
   
   
       13 . The sun visor assembly of  claim 12 , wherein the pivot controlling mechanism includes a protrusion formed on a lower side of the sun visor and more than one grooves, formed on an upper side of the extended member, for accommodating therein the protrusion when the extended member pivots about the sun visor. 
   
   
       14 . The sun visor assembly of  claim 13 , wherein the pivot controlling mechanism includes a separation preventing portion, formed on a rear end portion of more than one grooves, for supporting the protrusion, and controls a pivot angle of the extended member with respect to the sun visor. 
   
   
       15 . The sun visor assembly of  claim 12 , wherein the pivot controlling mechanism further includes magnetic members, attached on the lower side of the sun visor and the upper side of the extended member, for connecting with each other. 
   
   
       16 . The sun visor assembly of  claim 13 , wherein the pivot controlling mechanism further includes an engaged portion formed adjacent to one groove except for a front and a rear groove among said more than one grooves and a stopper accommodated in the engaged portion when the protrusion is accommodated in said one groove.
