  According to the present invention, it is possible to provide a head-mounted display with less display means shaking.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective view of a head mounted display device according to a first embodiment of the present invention, and FIG. 2 is a side view of the head mounted display shown in FIG.

  As shown in FIGS. 1 and 2, the head mounted display device includes a rear arm 3, two headphone units (side members) 4 and 5, an image display unit (display means) 6, a front arm (support arm) 7, and a support member ( Connecting means) 8 and an auxiliary arm 11.

  The rear arm 3 is attached to the back of the user H. The rear arm 3 has a rear arm main body 3A and a connecting portion 3B. The rear arm body 3A is formed in a U shape and has elasticity. The connecting portion 3B has a substantially ring shape and is provided at both ends of the rear arm main body 3A.

  The headphone unit 4 is attached to the left ear of the user H, and the headphone unit 5 is attached to the right ear of the user H. The headphone units 4 and 5 are pressed against the side of the user H by the elasticity of the rear arm body 3A.

  The video display unit 6 is attached to one end of the front arm 7.

  The front arm 7 supports the video display unit 6 so that the video display unit 6 is positioned in front of the left eye.

  The support member 8 has a bottomed cylindrical shape, and supports the front arm 7 so as to be movable in the front-rear direction D1 and detachable. One end of the support member 8 is inserted and fixed to the connecting portion 3B of the rear arm 3. One end of the support member 8 is rotatably connected to the casing 41 of the headphone unit 4. Accordingly, one end of the rear arm 3 is rotatably connected to the headphone unit 4 via the support member 8. The other end of the rear arm 3 is also rotatably connected to the headphone unit 5 by a support member 8. Therefore, the rear arm 3 can rotate around the virtual axis O1 connecting the two headphone units 4 and 5.

  The auxiliary arm 11 has an auxiliary arm main body 11A and a connecting portion 11B. The auxiliary arm body 11A is formed in a U shape and has elasticity. The connecting portion 11B has a substantially ring shape and is provided at both ends of the auxiliary arm main body 3A. One connecting portion 11B of the auxiliary arm 11 is rotatably attached to the support member 8 so as to be disposed between the connecting portion 3B of the rear arm 3 and the casing 41 of the headphone unit 4. The other connecting portion 11B of the auxiliary arm 11 is rotatably mounted on the support member 8 like the one connecting portion 11B. As a result, the auxiliary arm 11 can rotate around the virtual axis O1, as indicated by an arrow A in FIG.

  3 is a cross-sectional view of the lock mechanism of the head mounted display shown in FIG.

  As shown in FIG. 3, the casing 41 of the headphone unit 4 has a lock member accommodating portion 41a. The lock member accommodating portion 41a is formed with a first hole 41b and a second hole 41c.

  A lock member 42 is accommodated in the lock member accommodating portion 41a. The lock member 42 includes a locking portion 42a, a flange portion 42b, and a pin-like portion 42c. The locking portion 42a protrudes out of the lock member accommodating portion 41a through the first hole 41b. The collar portion 42b is coupled to the locking portion 42a, and prevents the locking portion 42a from dropping out of the first hole 41b and receives a spring force of a spring 43 described later. The pin-shaped portion 42c is coupled to the flange portion 42b, and is inserted into the second hole 41c so as to be slidable in the axial direction O2. Thereby, the latching | locking part 42 is guided to the axial direction O2. The axial direction O2 is eccentric from the virtual axis O1. A spring 43 is disposed between the flange 42b and the bottom 41d of the lock member housing 41a. The spring 43 always presses the flange portion 42b toward the connecting portion 11B of the auxiliary arm 11.

  A plurality of engaging recesses 111 are formed in the connecting portion 11B of the auxiliary arm 11 at predetermined intervals in the circumferential direction. The engaging recess 111 receives the locking portion 42 a of the lock member 42.

  The lock member accommodating portion 41a, the lock member 42, the spring 43, and the engagement recess 111 constitute a lock mechanism (lock means). In this locking mechanism, a part of the auxiliary arm 11 moves from the position where the auxiliary arm 11 entirely overlaps the rear arm 3 (the position indicated by the dotted line in FIG. 2) to the top side of the head of the user H at a predetermined angle ( For example, the auxiliary arm 11 is fixed at an arbitrary rotation position up to the rotated auxiliary arm use position (position indicated by a solid line in FIG. 2).

  When using the head mounted display device of this embodiment, as shown in FIGS. 1 and 2, the auxiliary arm 11 is rotated in advance so that the auxiliary arm 11 comes to the top of the head, and in this state the head mounted display device is It only has to be worn on the head.

  After mounting the head-mounted display device on the head, the video display unit 6 is moved along the front-rear direction D1 to move to a place where the video display unit 6 is easy to see.

  When the video display unit 6 is not used, the auxiliary arm 11 is rotated toward the rear arm 3 and is placed between the rear arm 3 and the back of the head as shown by the dotted line in FIG.

  According to this embodiment, since the auxiliary arm 11 is in contact with the head at a position away from the ear of the user H, the headphone units 4 and 5 are less likely to wobble, and the image display unit 6 is prevented from shaking even if the head moves. can do.

  When the video display unit 6 is not used, the auxiliary arm 11 can be rotated and stored between the rear arm 3 and the back of the head, so that the auxiliary arm 11 does not get in the way.

  Further, when the auxiliary arm 11 is rotated approximately 180 ° from the state shown in FIG. 1 and the head mounted display device is mounted on the head, the video display unit 6 can be viewed with the right eye.
