  Hereinafter, preferred embodiments for carrying out the present disclosure will be described in detail with reference to the drawings.

(overall structure)
FIG. 1 is a perspective view of a head mount display (HMD) according to an embodiment of the present disclosure. A head-mounted display is a device that is attached to the observer's head and provides a virtual reality experience to the observer by displaying virtual reality (VR) images (including still images and moving images). In other words, it can be said to be a head-mounted display device for virtual reality video. The head-mounted display 100 according to the present embodiment is a so-called immersive type, and is a type in which an observer who wears the head-mounted display 100 on the head exclusively views only a virtual reality image. However, the present invention is not limited to an immersive head-mounted display, and can be applied to, for example, a head-mounted display that displays a virtual reality image superimposed on the real world.

  The head mounted display 100 includes a display unit 10 and at least two (one set) head support members 20. The display unit 10 includes a device for displaying an image such as a liquid crystal display device or an organic electroluminescence device, and is a device for displaying a high-definition image for an observer wearing the head mounted display 100. Specific modes such as the shape of the display unit 10 and the video display method are not particularly limited.

  At least two head support members 20 are attached to substantially both ends of the display unit 10. As shown in FIG. 2, the head H of the observer is defined between the two head support members 20 by moving the head mounted display 100 in the mounting direction A so as to face the head H of the observer. Located in a space S (see FIG. 1). At this time, the two head support members 20 sandwich the observer's head H from both sides, and fix the display unit 10 to the observer's head H, particularly the front of the head H, as shown in FIG. Support to do.

  Each of the two head support members 20 includes a main support member 30 and a movable support member 40. The main support member 30 has a first end 32 attached to the display unit 10 and a second end 34 positioned on the opposite side of the first end 32, and in a direction of pressing the side surface of the observer's head H. It has the urging power of. The main support member 30 has a frame-like shape extending in a long shape, and is made of, for example, a resin leaf spring. However, the material constituting the main support member 30 is not particularly limited.

  Further, the main support member 30 of the head support member 20 is attached so that the first end 32 of the head support member 20 can be rotated in the vertical direction B (FIG. 3) at substantially both ends of the display unit 10 via the hinge unit 14. Yes. As described above, since the head support member 20 including the main support member 30 is movable in the vertical direction, individual differences such as differences in ear height due to differences in people, and differences in height between the left and right ears of each person. Can be absorbed.

  The movable support member 40 is positioned on the opposite side of the first end 33 and the first end 33 that are pivotally attached to the second end 34 of the main support member 30 about a hinge shaft 36 (see FIG. 4 and the like). The second end 35 is provided. As is apparent from the drawing, the length of the main support member 30 in the longitudinal direction is larger than the length of the movable support member 40 in the longitudinal direction. Since the length of the main support member 30 in the longitudinal direction is larger than the length of the movable support member 40 in the longitudinal direction, the head H of the observer can be reliably sandwiched from the side surface by the two main support members 30.

  FIG. 4 is a plan view of the head-mounted display 100 that is not attached to the observer's head before and after being attached to the observer's head H, as viewed from above, with the hinge shaft 36 as the center. The movable support member 40 rotates in the rotation direction (opening direction and closing direction) C. In the state of FIG. 4, the movable support member 40 is rotated outward and separated from each other. As is clear from this figure, the distance K1 between the first ends 32 of the two main support members 30 is larger than the distance K2 between the second ends 34 of the two main support members 30. That is, the distance between the two head support members 20 (two main support members 30) is narrowed from the front to the rear of the head mounted display 100, and the side of the observer's head H of the main support member 30 is pressed. Thus, the urging force in the direction to perform effectively functions, and the head mounted display 100 can be reliably fixed to the head H.

  Further, in a state in which the two movable support members 40 are rotated so as to be separated from each other, the second end 35 of the two movable support members 40 with respect to the interval K3 between the first ends 33 of the two movable support members 40. The interval K4 is larger. With such a configuration, it is possible to suppress interference between the head H and the second end 35 of the movable support member 40 even when the head mounted display 100 is moved in the mounting direction A during mounting. Further, by slightly increasing the interval K2 between the second ends 34 of the main support member 30 against the urging force of the main support member 30, smoother mounting is possible. Therefore, the head-mounted display 100 can be worn from the front of the observer's head H like ordinary glasses, and the hairstyle can be prevented from collapsing, which improves wearability.

  FIG. 5 is a plan view of the head mounted display 100 mounted on the observer's head H as seen from above. The movable support members 40 are pivoted inward and are close to each other. In this state, the two movable support members 40 are locked and support the rear surface of the observer's head H. In addition, the display unit 10 includes an elastic member 12 that comes into contact with the head H of the observer, particularly the front surface of the head H. The elastic member 12 is made of an elastic member such as sponge or rubber, functions as a face pad that covers the eyes of the observer, and can press the front surface of the head H of the observer. That is, the elastic member 12 can prevent the head-mounted display 100 from being displaced and can prevent light leakage from around the eyes.

  Further, the elastic member 12 can be provided with an uneven surface or a hole of a labyrinth structure. With such a configuration, light leakage can be prevented and steaming can be prevented. The elastic member 12 may be configured to be detachable from the display unit 10, and the display unit 10 can be shared among different observers, and the elastic member 12 can be replaced and used for each observer. Can be secured.

  That is, the elastic member 12 can press the front surface of the head H of the observer with the pressing force E1, and the two movable support members 40 rotated in the closing direction press the rear surface of the head H so as to approach each other. Since it can be pressed with the pressure E2, the head mounted display 100 is stably fixed to the head H in the front-rear direction E. Further, as already described, the main support member 30 has urging forces D1 and D2 in the direction of pressing the side surface of the head H of the observer, and the head mounted display 100 is stably in the left-right direction D. It is fixed to the head H. Therefore, a good fitting property to the head H of the head mounted display 100 can be obtained. Since the two movable support members 40 are locked at arbitrary positions, the movable support members 40 can be fixed at predetermined positions according to the size of the head H.

  The head mounted display 100 further includes a release button 38 as a release member that can release the locked state of the movable support member 40. By pressing the release button 38, the movable support member 40 in the state shown in FIG. 5 is rotated and separated in the opening direction (see FIG. 11), and the head mounted display 100 can be easily removed from the head H of the observer. Therefore, the detachability is improved. Even when an excessive force is applied to the head mounted display 100, the lock state is released without pressing the release button 38, and the head mounted display 100 rotates in the opening direction. Hereinafter, the operation mechanism of the movable support member 40 will be described in detail.

(Composition of connected parts)
FIG. 6 is an enlarged view showing the inside of the P portion of FIG. 1, and is a perspective view showing the structure of the connecting portion 50 between the main support member 30 and the movable support member 40. As described above, the movable support member 40 is attached to the second end 34 of the main support member 30 so as to be rotatable in the rotation direction C around the hinge shaft 36 of the connecting portion 50.

  FIG. 7 is an exploded perspective view including the connecting portion 50 and the like. In the connecting portion 50, the lid 51, the positioning member 52, the fixing member 53, the first coil spring (first urging member) 54, the first restricting cam 55, the moving cam 56, and the second restricting cam in order from the top. 57, a second coil spring (second urging member) 58, and a torsion coil spring (third urging member) 59 are arranged. The hinge shaft 36 includes a central through hole of all members from the lid 51 to the torsion coil spring 59, a storage space 34a of the second end 34 of the main support member 30, and a storage space 42a of the main body 42 of the movable support member 40. It penetrates. Also, a release button 38 as a release member is attached to one end of the second restriction cam 57 and is disposed at the second end 34 of the main support member 30, which is a position away from the hinge shaft 36. .

  FIG. 8 is a cross-sectional view taken along the line XX of FIG. 6, and only the top of the release button 38 is shown because of the viewing direction, and the positioning member 52 is not shown. The lid 51, the positioning member 52, the fixed member 53, and the first coil spring 54 are stored in the storage space 42 a of the main body 42 of the movable support member 40. The moving cam 56, the second restriction cam 57, the second coil spring 58, and the torsion coil spring 59 are accommodated in the accommodation space 34 a of the second end 34 of the main support member 30. The first restriction cam 55 is stored so as to straddle both the storage space 42a and the storage space 34a.

  The lid 51 is a member that closes the upper surface of the storage space 42a. The positioning member 52 is a member that holds the release button 38 at a predetermined position and determines the position. The fixing member 53 is a member that holds the end portion of the hinge shaft 36 penetrating through the central through hole of each member by the through hole and fixes the end of the hinge shaft 36 to the main body 42 of the movable support member 40. Therefore, as the hinge shaft 36 rotates, the fixed member 53 and the main body 42 of the movable support member 40 always rotate (turn).

  The first coil spring 54 and the second coil spring 58 are compressed in the state shown in FIG. 8, and the first restriction cam 55, the moving cam 56, and the second restriction cam 57 attached to the hinge shaft 36 are compressed. It plays a role of pressing and pressing downward or upward by a biasing force. The first coil spring 54 urges and pushes down the first restriction cam 55, the moving cam 56, and the second restriction cam 57 by the urging force. On the other hand, the second coil spring 58 urges the first restricting cam 55, the moving cam 56, and the second restricting cam 57 upward by the urging force to push up. In the present embodiment, the biasing force of the first coil spring 54 is set to be larger than the biasing force of the second coil spring 58 (the biasing force of the first coil spring 54> the second coil spring. 58 biasing force).

  The first restricting cam 55 restricts the movement of the moving cam 56 in the engaged state with the moving cam 56 and can also take a non-engaged state in which the engagement with the moving cam 56 is released. It is also possible to rotate relative to the cam 56. The operation of the first restriction cam 55 will be described in detail later.

  The moving cam 56 is relatively relative to the first restriction cam 55 or the second restriction cam 57 so as to be engaged with or disengaged from the first restriction cam 55 or the second restriction cam 57. The movable support member 40 is moved and the movable support member 40 can be rotated, or the movable support member 40 is locked to be locked, and the movable support member 40 is locked in a predetermined position. The operation of the moving cam 56 will be described in detail later.

  The second restricting cam 57 restricts the movement of the moving cam 56 in a state where it is engaged with the moving cam 56, and can also take a non-engaged state in which the engagement with the moving cam 56 is released. It is also possible to rotate relative to the cam 56. In addition, as shown in FIG. 7, a release button 38 is attached to one end of the second restriction cam 57, and a release operation of pushing down the second restriction cam 57 with the release button 38 is realized. The operation of the second restriction cam 57 will be described in detail later.

  One end of the torsion coil spring 59 is engaged with an engagement groove 42 b (see FIG. 7) formed in the main body 42 of the movable support member 40, and the torsion coil spring 59 is formed in the storage space 34 a of the second end 34 of the main support member 30. It is fixed at a fixed position (see FIG. 8). Therefore, when the movable support member 40 is closed as shown in FIGS. 4 to 5, torque (torsional moment) acts on the torsion coil spring 59. Then, during the releasing operation by the release button 38, the movable support member 40 is opened as shown in FIG. 4 by the urging force generated when the torque is released. The operation of the torsion coil spring 59 will also be described in detail later.

  FIGS. 9A and 9B are diagrams showing a state before the head mounted display 100 is mounted. FIG. 9A is a plan view seen from above, and FIG. 9B is a side view showing the inside of the connecting portion 50 seen from the side. FIG.

  In this state, both the urging force α1 of the first coil spring 54 and the urging force β1 of the second coil spring 58 act effectively, and the three cams are in close contact with each other. That is, the first restricting cam 55, the moving cam 56, and the second restricting cam 57 are moved from the first coil spring 54 to the second force by the downward biasing force α1 from above and the upward biasing force β1 from below. It is sandwiched between the coil springs 58 and is in close contact with and engaged. Further, although a certain amount of torque is applied to the torsion coil spring 59, an urging force that opens the movable support member 40 is not generated.

  10A and 10B are views showing the operation when the head mounted display 100 is mounted. FIG. 10A is a plan view seen from above, and FIG. 10B shows the inside of the connecting portion 50 seen from the side. It is a side view. In a state where the observer's head H is disposed in the space S, a force for rotating the movable support member 40 in the closing direction C1 (closing direction) is applied. At this time, together with the hinge shaft 36, the fixed member 53 fixed to the main body 42 of the movable support member 40, the first restricting cam 55 pushed down by the strong biasing force α1 of the first coil spring 54, and the moving cam 56 are also provided. It moves in the rotation direction C1. This state is substantially the same as the state of FIG. 5, but is more closed than the state of FIG. 5, that is, two movable support members 40 are closer to each other than the state of FIG. ing.

  Here, as described above, the biasing force α1 of the first coil spring 54 is larger than the biasing force β1 of the second coil spring 58 (the biasing force α1 of the first coil spring 54> the second coil). The biasing force β1) of the spring 58). Therefore, the moving cam 56 urged downward by the urging force of the first coil spring 54 against the upward urging force of the second coil spring 58 against the upward force of the second coil spring 58. While the second restriction cam 57 is pushed down, the engagement with the second restriction cam 57 is released, and the second restriction cam 57 rotates in the rotation direction C1 independently of the second restriction cam 57. That is, as shown in FIG. 10B, the sawtooth engagement teeth 56 a formed on the lower surface of the moving cam 56 are sawtooth engagement teeth formed on the upper surface of the second restriction cam 57. When the engagement with the second restricting cam 57 is released by releasing the engagement with the 57a and overcoming the engagement teeth 57a, the moving cam 56 rotates in the rotation direction C1.

  A saw blade-like engagement tooth 56 a formed on the lower surface of the moving cam 56 is inclined with respect to the inclined surface 56 a 1 formed so as to be largely inclined with respect to the main body of the moving cam 56 and the main body of the moving cam 56. And a substantially vertically upright vertical surface 56a2. On the other hand, the sawtooth engagement teeth 57 a formed on the upper surface of the second restriction cam 57 are also inclined surfaces 57 a 1 that are largely inclined with respect to the main body of the second restriction cam 57 and the second restriction cam 57. And a vertically standing vertical surface 57a2 that is substantially not inclined with respect to the main body (see FIG. 8). Since the rotation direction C1 is a direction in which the vertical surface 56a2 and the vertical surface 57a2 that are in close contact with each other in the state of FIG. 9 are separated, the engagement tooth 56a can easily get over the engagement tooth 57a.

  The first coil spring 54 and the second coil spring 58 are in the same state as in FIG. 9 at a position where the force to turn the movable support member 40 in the turning direction C1 is stopped, and the first coil spring 54 and the second coil spring 58 are in the same state as in FIG. The restricting cam 55, the moving cam 56, and the second restricting cam 57 are also in the same positions as in FIG. 9, and the moving cam 56 and the second restricting cam 57 are engaged again. At this time, the engaging tooth 56a is engaged again with the engaging tooth 57a. At this time, a slight force in the rotational direction C2 (see FIGS. 8 and 11) opposite to the rotational direction C1, that is, the direction to open the two movable support members 40 (a force smaller than a predetermined value that is not an excessive force). ) Does not open the movable support member 40. This is because the rotation direction C2 is a direction in which the vertical surface 56a2 and the vertical surface 57a2 are further pressed against each other, so that the engagement teeth 56a cannot easily get over the engagement teeth 57a. Therefore, since the movable support member 40 does not easily open even if an observer inadvertently applies a force to open the movable support member 40 with the head-mounted display 100 mounted on the head H, it can be easily mounted. It can prevent shifting.

  In the state of FIG. 9, the concavo-convex concavo-convex engagement portion 56 b formed on the upper surface of the moving cam 56 and the concavo-convex concavo-convex engagement portion 55 b ( Are engaged with each other. The first restricting cam 55 is biased toward the moving cam 56 by the first coil spring 54, and this engagement is not released even in the operation of FIG.

  In FIG. 10, a torque (torsion moment) is applied to the torsion coil spring 59 by applying a torsional force in the rotation direction C1 (closing direction), and the torsion coil spring 59 in a torsion state maintains this torque. ing.

  FIG. 11 is a diagram showing the operation of the head mounted display 100 when the release button 38 is pushed from the state of FIG. 10, FIG. 11 (a) is a plan view seen from above, and FIG. 11 (b) is from the side. It is the side view which shows the inside of the connection part 50 which looked. When the release button 38 is pressed in the pressing direction F, the second restricting cam 57 connected to the release button 38 is also pushed down along the axial direction of the hinge shaft 36, and the second restricting cam 57 and the moving cam 56 are engaged. To release. Then, the torque generated in the torsion coil spring 59 in the closed state shown in FIG. 10 is released, and the movable support member 40 is rotated in the rotation direction C2 (opening direction) with the biasing force acting in the opposite direction to the torque, and is opened. A state is realized. That is, the movable support member 40 is opened, and the head mounted display 100 can be easily detached from the observer's head H, so that the detachability is improved.

  FIG. 12 differs from normal removal as shown in FIG. 11 in that an excessive force is exerted on the movable support member 40 in the opening direction as when the movable support member 40 is forcibly opened from the closed state of FIG. FIG. 12A is a plan view seen from above, and FIG. 12B is a side view showing the inside of the connecting portion 50 seen from the side. . In the state of FIG. 10, the concavo-convex engaging portion 55 b formed on the lower surface of the first restricting cam 55 is engaged with the concavo-convex engaging portion 56 b formed on the upper surface of the moving cam 56.

  As described above, even if a slight force (not excessive force, smaller than a predetermined value) is applied in the rotation direction C2 that opens the movable support member 40, the engagement teeth 56a can easily get over the engagement teeth 57a. Therefore, the engagement between the moving cam 56 and the second restricting cam 57 is not released, and the movable support member 40 does not move. However, even when an excessive opening force (a force greater than a predetermined value) is applied as when it is forcibly opened, there is a risk that each member may be damaged if such engagement is maintained. In addition, the safety of observers and the like may be impaired.

  Therefore, in the present embodiment, as shown in FIG. 12B, the first regulating cam 55 responds to an excessive opening force with the strong biasing force α1 (see FIG. 9) of the first coil spring 54. On the contrary, it moves upward while compressing the first coil spring 54 with a stronger pushing force α2. Then, when the concavo-convex engaging portion 55b gets over the concavo-convex engaging portion 56b, the engagement between the concavo-convex engaging portion 55b and the concavo-convex engaging portion 56b is released (see FIG. 7). Then, the engagement between the first restriction cam 55 and the moving cam 56 is released. As a result, the first regulating cam 55 rotates in the rotation direction C2 (opening direction) independently of the moving cam 56, and the movable support member 40 also rotates in the rotation direction C2.

  The concavo-convex engaging portion 56b formed on the upper surface of the moving cam 56 has an inclined surface 56b1 which is largely inclined with respect to the main body of the moving cam 56, and a vertical standing upright which has no substantial inclination with respect to the main body of the moving cam 56. Surface 56b2 (see FIG. 7). On the other hand, the concavo-convex engaging portion 55 b formed on the lower surface of the first restriction cam 55 is also inclined with respect to the inclined surface 55 b 1 greatly inclined with respect to the main body of the first restriction cam 55 and the main body of the first restriction cam 55. And a vertically standing vertical surface 55b2 that is substantially free of inclination (see FIG. 7). The rotation direction C2 is a direction in which the vertical surface 56b2 and the vertical surface 55b2 that are in close contact with each other in the state of FIG. As a result, the movable support member 40 is released from the locked state and can be rotated, thereby preventing breakage and releasing an excessive force such as an unexpected collision, thereby ensuring safety.

  The head mounted display 100 is not limited to the one described above, and various modifications can be made.
