Moreover, the front sectional view outer shape of the full face type helmet 601 is a substantially elliptical shape that is long in the vertical direction, and the size varies depending on the front and rear positions where the cross section is taken. In the front view of FIG. 5 and the rear view of FIG. 8, the maximum outer shape in the front sectional view is represented by the outline B, and the right side view in FIG. This outline is represented by a one-dot chain line B extending vertically. In the following, the region in front of the front and rear position where the front sectional view outer shape indicated by the alternate long and short dash line B shown in FIG. 7 is maximum is referred to as the front region 62a of the helmet 60, and the rear region is referred to as the rear region 62b of the helmet 60. . In addition, the left and right widths of the outer shape of the helmet 601 in the cross-sectional view are the largest in the vicinity of the center of the front and rear where the alternate long and short dash line B passes, and the widths of the left and right are reduced from the position toward the front or rear. . The jet-type helmet 602 and the off-road helmet 603 have substantially the same shape.

  Next, the structure of the HMD device 1 will be described. As shown in FIGS. 4 to 9, in a state where the HMD device 1 is attached to the helmet 60, the holder 10 is provided so as to hold the outside of the helmet 60, and the housing 2 is disposed on the top of the helmet 60. The screen 4 is disposed on the front upper part of the helmet 60.

  The entire holder 10 is integrally molded from a synthetic resin material and has elasticity. The holder 10 includes a pair of left and right left portions 10L and 10R. Each of the left portion 10L and the right portion 10R is formed in a smoothly curved belt shape and has a Z-shape when viewed from the side. That is, the left part 10L and the right part 10R of the holder 10 are respectively a first holding part 11 extending in the front-rear direction, a second holding part 12 extending from the front end of the first holding part 11 obliquely rearward and upward, and a second holding part. 12 and a third holding portion 13 extending forward from the rear end. Furthermore, the holder 10 has a fourth holding portion 14 provided by connecting the rear ends of the left and right first holding portions 11, 11, and is provided by connecting the front end portions of the left and right third holding portions 13, 13. A connecting portion 15 is provided. By the fourth holding part 14 and the connecting part 15, the pair of left and right first to third holding parts 11 to 13 form an integral loop shape. Further, a rib portion 16 is provided so as to connect the first holding portion 11 and the second holding portion 12. As a result, the second holding part 12 is less likely to swing up and down around the front end that is the boundary with the first holding part.

  The flat surface of the first holding part 11 is directed substantially in the left-right direction, and the first holding part 11 is curved in an arch shape so as to be convex outward in the left-right direction. The second holding portion 12 extends obliquely rearward and upward from the front end of the first holding portion 11 so as to be cut and twisted in the left and right sides. Due to this twisting, the flat surface of the second holding part 12 is directed substantially in the left-right direction at the front end connected to the first holding part 11, but is directed substantially in the front-rear direction at the rear end. . The flat surface of the third holding portion 13 is directed substantially in the vertical direction, and the third holding portion 13 is curved in an arc shape so as to be convex upward. A bolt 17 is attached to the central portion of the connecting portion 15, and a suction cup protruding downward from the connecting portion 15 is provided at the lower end of the bolt 17. The suction cup can be adjusted in the vertical position according to the rotation of the bolt 17. Further, the bolt 17 and the suction cup are received in a slit groove 18 formed to extend in the front-rear direction at the connecting portion 15, and the front-rear position can be adjusted along the slit groove 18.

  10 is a view taken in the direction of arrows XX in FIG. As shown in FIG. 10, the width (the vertical dimension in FIG. 10) of the first holding unit 11 decreases from the back surface 11 a side that is in close contact with the outer surface of the helmet 60 toward the surface 11 b side that is the opposite side. It has become. Although not shown, the second to fourth holding portions 12 to 14 are formed in the same manner.

  As shown in FIGS. 6 and 7, an adjustment mechanism 20 is provided between the housing 2 and the holder 10 to adjust the attachment position of the housing 2 with respect to the holder 10 in the front-rear direction. The adjustment mechanism 20 is provided to project obliquely upward and rearward at the rear part of the left and right third holding parts 13, extends rearward from the housing 2, and extends in the rearward direction from the housing 2 so as to cover the ribs 21 from above. And a pair of left and right brackets 22 provided. A locking portion (not shown) that extends forward and backward on the back side of the bracket 22 is fitted between adjacent adjacent ribs 21. As a result, the bracket 22 is locked to the rib 21.

  The bracket 22 has a slit groove 23 extending in the front-rear direction. A nut (not shown) is provided at the front end of the third holding portion 13 so as to protrude upward, and the nut is disposed in the slit groove 23 when the bracket 22 is engaged with the rib 21. A bolt 24 is screwed onto the nut via a washer having a diameter larger than the width of the slit groove 23. When the bolt 24 is tightened downward, a downward pressing force from the washer acts on the bracket 22, and the bracket 22 is firmly attached to the third holding portion 13.

  When the bolt 24 is loosened and moved upward in the adjusting mechanism 20, the engagement between the rib 21 and the bracket 22 is released, and the housing 2 can be lifted upward. When the bolt 24 is loosened in this way, the front-rear position of the housing 2 is adjusted along the slit groove 23, the housing 2 is lowered at a desired position, and the locking portion of the bracket 22 is again adjacent to the locking rib. 21 is fitted. Further, the bolt 24 is tightened, and the washer is brought into close contact with the periphery of the slit groove 23 on the upper surface of the bracket 22. As a result, the bracket 22 is fixed to the third holding part 13, and the mounting position of the housing 2 connected to the bracket 22 and the screen 4 attached to the housing 2 with respect to the holder 10 is changed.

  As shown in FIGS. 5 and 6, the screen 4 protrudes from the left and right ends and is integrally formed with pins 7. The screen 4 is attached to the image projection unit 3 so as to be swingable up and down by tightly fitting the pin 7 in a boss hole formed so as to be recessed in the left-right direction at the front end portion of the housing 2. Although the screen 4 is swingable, the screen 4 is configured to stop at that position when the swinging external force becomes free.

  In order to attach the HMD device 1, the attachment position of the image projection unit 3 and the screen 4 with respect to the holder 10 is adjusted in advance at a predetermined position using the adjustment mechanism 20. In addition, the front and rear positions of the suction cups are adjusted in advance. Then, the front end of the first holding unit 11 is elastically deformed outward in the left and right directions, and the front end of the third holding unit 13 is elastically deformed upward and attached to the helmet 60 from the rear side. And the deformation | transformation of the 1st holding | maintenance part 11 and the 3rd holding | maintenance part 13 is cancelled | released in the state which contact | adhered the flat surface of the 4th holding | maintenance part 14 to the rear part of the lower area | region 61a of the helmet 60. Then, as shown in FIG. 7, the flat surface of the first holding unit 11 is in close contact with the lower region 61 a of the helmet 60 across the front and rear. Further, the flat surface of the second holding part 12 is in close contact with the rear part of the lower region 61a of the helmet 60 and the rear part of the upper region 61b. At this time, since the second holding portion 12 is twisted as described above, the second holding portion 12 is firmly attached to the outer surface of the helmet 60 having a curved surface. The flat surface of the third holding unit 13 is in close contact with the upper region 61 b of the helmet 60 across the front and rear. Moreover, the connection part 16 closely_contact | adheres so that the upper center part of a helmet may be covered. The holder 10 exhibits a restoring force toward the inside of the helmet 60 and holds the helmet 60 from the outside so as to hold it. Then, the bolts 17 are tightened so that the suction cups are attracted to the outer surface of the helmet 60.

  When the helmet 60 to which the HMD device 1 is attached is thus mounted and the motorcycle 50 is traveled, traveling wind pressure acts on the HMD device 1. As shown in FIG. 10, the first to fourth holding portions 11 to 14 have a width that decreases from the back surface side that is in close contact with the outer surface of the helmet 60 toward the opposite surface side. Moreover, as shown in FIG. 6, the front end of the screen 4 is sharp. For this reason, the traveling wind blown to the HMD device 1 smoothly flows backward, and air resistance acting on the HMD device 1 is reduced.

  Although the HMD device 1 may be subjected to external force due to the influence of air resistance or the like during traveling, the HMD device 1 maintains a state of being in close contact with the helmet 60 against such external force and is difficult to be removed from the helmet 60. Yes. That is, when a leftward external force is applied to the HMD device 1, the first to third holding portions 11 to 13 of the right portion 10 </ b> R are kept in close contact with the helmet 60. When the rightward external force is applied, the first to third holding portions 11 to 13 of the left portion 10 </ b> L are kept in close contact with the helmet 60. When an upward external force is applied, the pair of left and right first holding portions 11 that are in close contact with the lower region 61a do not move to the upper region 61b and are maintained in close contact with the helmet 60. In addition, the pair of left and right second holding portions 12 maintains the state of being in close contact with the helmet 60 because the front end portion in close contact with the lower region 61a does not move to the upper region 61b. When a downward external force is applied, the pair of left and right third holding portions 13 that are in close contact with the upper region 61b do not move to the lower region 61a but are maintained in close contact with the helmet 60. When a rearward external force is applied, the pair of left and right first to third holding portions 11 to 13 do not move the front end portion in close contact with the front region 62a to the rear region 62b. Maintain close contact. When a forward external force is applied, the rear end portion of the pair of left and right first to third holding portions 11 to 13 that are in close contact with the rear region 62b does not move to the front region 62a. Maintain close contact. Further, the state where the fourth holding part is in close contact with the helmet is maintained.

  At this time, the housing 2 is disposed on the top of the helmet 60, and the screen 4 is disposed so as to cover the front upper side of the shield 65 of the helmet 60. Therefore, the image reflected by the screen 4 is located in the peripheral visual field above the central visual field in the visual field from the inside of the helmet 60 of the user of the helmet 60. In addition, since the screen 4 is a half mirror, the user of the helmet 60 can see through the portion of the screen 60 where the image is not projected and visually recognize the scene in front of it. For this reason, even if the screen 4 is arranged so as to cover the front side of the shield, the user's field of view is not narrowed.

  When the user of the helmet 60 does not need to provide an image from the HMD device 1, the screen 4 can be swung around the axis of the pin 7 and retracted above the shields 651 and 652. When an operation of swinging to retract the screen 4 is performed, the screen 4 is stopped at a position where the operating hand is separated, and the screen 4 is maintained in the retracted state.

  Thus, by retracting the screen 4 to the upper side of the shield, the shield 65 can be swung without interfering with the screen 4. The direction in which the shields 651 and 652 are opened and the direction in which the screen 4 is retracted are the same direction. For this reason, if the shield 65 is swung to open it, the shield 65 and the screen 4 are engaged with each other, and the screen 4 can be swung upward together with the shield 65, and the screen 4 can be swung easily. be able to.

  When removing the HMD device 1 from the helmet 60, the first holding part 11 may be elastically deformed so as to push it left and right, and the third holding part 13 is bent upward, while pulling out the whole rearward.

  The HMD device 1 is separate from the helmet 60 and can be used among a plurality of helmets 60. For this reason, it is not necessary to buy a helmet with a built-in display device. Further, the helmet can be exchanged regardless of the HMD device 1.

  Here, as shown in FIG. 7, the front ends of the pair of left and right first holding portions 11 and the front ends of the second holding portions 12 are positioned forward of the alternate long and short dash line B but extend to the front side of the helmet 60. It stays at the side. For this reason, it can resist external force to the rear, and can be diverted between each of the three types of helmets 601, 602, and 603 having different front and lower shapes as shown in FIG. By forming the first holding unit 11 and the second holding unit 12 in this way, the versatility of the HMD device 1 is enhanced.

  The holder for holding the helmet 60 includes first to fourth holding portions 11 to 14 formed in a band shape, and holds the helmet 60 from the outside with a simple structure having a Z-shape in a side view and holds the helmet 60 firmly. The structure is realized. For this reason, the HMD device 1 can be reduced in size and weight.

  So far, the embodiments of the HMD device and the information disclosure device according to the present invention have been described. However, the scope of the present invention is not necessarily limited to the above range, and can be changed as appropriate. For example, you may provide elastic bodies, such as a rubber material, a silicon | silicone, and a resin material, in the back surface of the holder 10 (namely, at least any one of the 1st thru | or 4th holding | maintenance parts 11-14, the connection part 15, and the rib part 16). Thereby, the adhesiveness with respect to the helmet 60 of the holder 10 improves, and it becomes difficult to remove the HMD apparatus 1 from a helmet further.

  The display according to the present invention is not limited to the segment type projection device using LEDs, and may be other modes such as a liquid crystal display device.
