Mounting unit for head mounted apparatus and head mounting apparatus

Abstract

A mounting unit that can be worn easily and in which size adjustment and lock release can be operated with a natural hand position is disclosed. The mounting unit includes a front frame and a rear frame. The rear frame being connected to the front frame can move in a back and forth direction with respect to the front frame. And the unit includes knob members which are provided on both the right and left portions of the rear frame, for operation of backward movement of the rear frame. Furthermore, the unit includes lock mechanisms which prevent the backward movement of the rear frame with lock release buttons which allow release of the lock of the lock mechanisms. The knob members are arranged under both frames. Each of the lock release buttons is arranged at a portion on each of the knob members where the user pushes with his/her finger when a user will move the rear frame backward with respect to the front frame.

1. A mounting unit for mounting a main apparatus of a head mounted apparatus on the front side of the head of a user, comprising:
 a front frame whose front portion is fixed to the main apparatus, and whose right and left portions extend in a front-and-rear direction,  
 a rear frame which is connected to the front frame at its right and left portions and is capable of moving in the front-and-rear direction with respect to the front frame, and has a portion that presses the back of the user's head,  
 knob members which are provided on both the right and left portions of the rear frame, when the knob members are pushed backward the rear frame moves backward with respect to the front frame,  
 lock mechanisms which prevent the backward movement of the rear frame,  
 release buttons which allows a lock release operation of the lock mechanisms to be performed,  
 wherein, each of the knob members is arranged under both the frames, and, each of the release buttons is arranged such that the user may push with a finger on each of the knob members in order to move the rear frame backward with respect to the front frame.  
 
     
     
       2. The mounting unit according to  claim 1 , wherein, each of the release buttons is provided at the portion on each knob member where a user's thumb is applied while holding the front frame from the side direction in a state of being worn upon the user's head. 
     
     
       3. The mounting unit according to  claim 1 , wherein a top surface of the knob member is separated from a lower surface of the front frame. 
     
     
       4. The mounting unit according to  claim 1 , wherein the front frame is a member which has elasticity, and is connected to the rear frame in a state of being biased toward a direction of expanding to the right and left. 
     
     
       5. The head mounted apparatus comprising:
 a main apparatus which is arranged at the front of a user's head; and  
 the mounting unit according to  claim 1 , which is fixed on the main apparatus.  
 
     
     
       6. The head mounted apparatus according to  claim 5 , wherein the main apparatus is arranged in front of user's eyes, and displays an image.
