The spherical body portion 6 is formed in a spherical shape, and the spherical body portion 6 is held by a spherical seat 9 of an attachment body holding portion 8 provided at a lower front portion of the holding body 3. A configuration in which the optical device O is held by the spherical portion 6 of the attachment body 2 and the spherical seat 9 of the holding body 3 is a spherical joint structure 19. In this embodiment, the optical device O is attached to the bracket 5 with a bolt 7.

  The holding body 3 is slidable in the left-right direction along the guide portion 21 provided on the guide support body 4. The guide support body 4 is formed in a horizontally long shape that can be provided with a guide portion 21 that can slide the holding body 3 in front of the user and in the left-right direction from the front of the user. For example, it can be adjusted to an arbitrary position within a range of 110 mm, which sufficiently covers 65 mm, which is the distance between both eyes by ergonomics. The guide support body 4 is provided with a configuration related to a helmet attachment 42 described later.

  As shown in FIGS. 2 and 3, the spherical body portion 6 of the mounting body 2 is formed in a spherical shape, and the spherical seat 9 of the holding body 3 is formed in a spherical surface that matches the spherical body portion 6. The spherical seat 9 is composed of a fixed side seat surface 10 formed integrally with the holding body 3 and a movable side seat surface 11 facing the fixed side seat surface 10. In this embodiment, the spherical seat 9 has a truncated cone shape that sandwiches the spherical body portion 6 from the left-right direction. By widening the open range in the vertical direction of the mounting body holding portion 8, The movable range of the sphere 6 is expanded. In this embodiment, the open range of the attachment body holding portion 8 is formed from the lower rear to the upper front with respect to the holding position of the spherical portion 6, and the spherical body portion 6 is spherically seated from the left and right directions by this attachment body holding portion 8. 9, the movable range of the optical device O is greatly expanded in the vertical direction.

  Further, by using different resins for the spherical portion 6 and the spherical seat 9, slidability, durability and holding force are secured. As this resin, a resin that has lubricity and is movable even when foreign matter enters is preferable. In addition, in this way, the configuration for holding the optical device O so that the posture can be changed is made of resin, thereby reducing the weight and reducing the influence on the magnetic product. In addition, by adopting a spherical joint structure (ball joint structure) provided with a spherical portion 6 of an appropriate size, the robustness and maintainability are improved, the cost is reduced, and the influence on magnetic products is reduced.

  The movable side seating surface 11 located on the right side of the figure is formed on the spherical body 6 side of the cylindrical spherical seating member 13 inserted in the through hole 12 provided in the holding body 3. A female screw 14 is formed on the side of the through hole 12 opposite to the holding portion, and an adjustment member 16 having a male screw 15 formed on the outer periphery thereof is screwed from the side of the through hole 12 opposite to the holding portion. A disc spring 17 is inserted between the adjusting member 16 and the spherical seat member 13, and the spherical seat member 13 is pressed against the spherical portion 6 by the spring force of the disc spring 17 by screwing the adjusting member 16. . A portion where the spherical seat member 13 is pressed against the sphere portion 6 by the disc spring 17 is a holding force adjusting portion 18 that adjusts the holding force of the sphere portion 6. The force that presses the spherical portion 6 with the spherical seat member 13 can be adjusted by the number of the disc springs 17 and the screwing amount of the adjusting member 16. In this embodiment, a large force can be obtained in a space-saving manner by adjusting the support force using the disc spring 17. The disc spring 17 may be another elastic member.

  In this embodiment, by adopting a configuration in which the spherical portion 6 having an appropriate diameter is held by such a holding force adjusting portion 18, for example, a holding force of about 150 N or more can be secured and stable. The optical device O can be held. In consideration of a decrease in holding force due to wear of the sphere 6, the holding force by the holding force adjusting unit 18 can be adjusted to 230 N, which is about 1.5 times.

  In this way, holding the spherical portion 6 of the mounting body 2 to which the optical device O is attached by the spherical seat 9 capable of adjusting the support force, the holding force is adjusted according to the size, shape, etc. of the optical device O. Easy to do. Moreover, when it is desired to rotate the optical device O in the vertical direction, if the optical device O is rotated with a force equal to or greater than the holding force, the sphere 6 rotates along the spherical seat 9. Can be easily rotated to ensure visibility. In addition, since the sphere 6 can be adjusted to an arbitrary position in the range of 360 degrees along the spherical seat 9, the optical device O is rotated upward as shown in FIG. It can be easily rotated and turned sideways. In the spherical joint structure of this embodiment, the spherical body portion 6 is provided on the attachment body 2 and is held by the spherical seat 9 of the holding portion 8. However, the spherical body portion 6 is provided on the holding portion 8 side, and the attachment body 2 is provided. A spherical seat 9 may be provided and held on the side.

  4 is a central longitudinal cross-sectional view of the optical device holding device shown in FIG. 1, FIG. 5 is an enlarged cross-sectional view showing the guide portion and the guide portion of FIG. 4, and FIG. 6 is an optical device hold shown in FIG. It is a disassembled perspective view which shows the guide part and guide part of an apparatus.

  As shown in FIGS. 4 and 5, a guide portion 21 on which the holding body 3 slides in the left-right direction is provided at the front portion of the guide support body 4 so as to protrude toward the holding body 3. On the other hand, a guide portion 22 that slides in the left-right direction along the guide portion 21 is formed at the rear portion of the holding body 3. The guide portion 21 is formed in a convex shape extending in the left-right direction, and the guide portion 22 is formed in a concave shape in which the width direction of the central portion is recessed so as to contact the guide portion 21 at the upper and lower portions. The guide portion 21 and the guide portion 22 are formed so that the vertical position is an arc shape, and a part of the arc of the guide portion 21 and the guide portion 22 is in contact. In this way, the holding body 3 and the guide support body 4 are engaged only in the vertical positions of the guide portion 21 and the guide portion 22, and the holding body between the upper and lower guide portions 21 and the guide portion 22. 3 and the guide support 4 are in a state where the space 23 is maintained.

  As shown in FIG. 5, the guide portion 21 and the guide portion 22 are engaged with each other by forming a guide groove 24 (a slight depression shown in the figure) extending in the left-right direction in the guide portion 21 located on the upper side. The upper guide portion 22 is engaged with 24. That is, the guide support body 4 is provided with a convex guide portion 21 to increase the strength and rigidity, and the engagement between the guide support body 4 and the holding body 3 is slightly fitted on the upper side. Thus, rattling when the holding body 3 slides in the left-right direction is suppressed, and the optical device O (FIG. 1) can be stably slid in the left-right direction.

  Further, as shown in FIGS. 4 and 5, between the holding body 3 and the guide support body 4, there is provided a support portion 25 that supports the support body 3 to the guide support body 4 with an appropriate force. The support portion 25 includes a support member 26 that contacts the guide portion 21 of the guide support body 4, a pressure member 27 that presses the support member 26 against the back surface of the guide support body 4, and a pressing force of the pressure member 27. And a fixing block 29 for holding the front end side of the support bolt 28 on the holding body 3 side. In addition, an opening 34 that enables the support bolt 28 that supports the holding body 3 to the guide support 4 in this way to move in the left-right direction of the guide support 4 is provided at the center in the vertical direction of the guide 21. Is provided.

  The support portion 25 is configured such that the support bolt 28 is inserted into the holding body 3 from the guide support body 4 side, and the male screw portion 30 provided at the tip is screwed into the female screw portion 31 provided in the fixed block 29. Accordingly, the head 32 of the support bolt 28 presses the pressure member 27, and the pressure member 27 presses and supports the support member 26 against the guide portion 21. Thereby, the guide part 22 of the holding body 3 and the guide part 21 of the guide support body 4 are in contact with each other with a preferable force. The portion of the support bolt 28 that presses the support member 26 against the guide portion 21 via the pressure member 27 is a support force adjustment portion 37 that adjusts the support force of the support portion 25.

  In this embodiment, an appropriate support force is obtained by using a plurality of disc spring materials superimposed on the pressure member 27. In this case, the holding body 3 is supported by the guide support body 4 by inserting a shim ring 36 (for example, about 0.1 to 0.3 mm) between the disc spring material 27 and the head 32 of the support bolt 28. The force to be adjusted can be easily adjusted, and can be adjusted to an appropriate force with a simple configuration. As the support force, for example, a holding force of about 15 N is fixedly set, and when the holding body 3 is worn out in the future and the holding force is lowered, the support force adjustment by the shim ring 36 may be performed. When it is necessary to increase the support force due to the mass of the optical device O, the shim ring 36 is inserted between the pressurizing member 27 and the head 32 of the support bolt 28 so as to have a pressure of about 20 N. Support force adjustment is possible. The pressurizing member 27 may have a configuration other than a disc spring, as long as the supporting force of the holding body 3 by the guide support body 4 can be adjusted to an appropriate force (for example, about 15N to about 20N). Good.

  In this embodiment, a flange 33 for limiting the tightening amount of the support bolt 28 is provided at a position close to the holding body 3 of the support bolt 28. The flange portion 33 prevents the support bolt 28 from being tightened excessively. In a normal use state, the holding body 3 and the gap t are vacant. Even if the support bolt 28 is tightened excessively, the gap t is tightened. It abuts against the holding body 3 so that no further tightening is possible. Thus, the user guides the holding body 3 so that the support member 26 is in contact with the back surface side of the guide portion 21 of the guide support body 4 and only the upper and lower guide portions 22 are in contact with the front surface side of the guide portion 21. The frictional resistance when sliding the support 4 in the left-right direction is made appropriate.

  Therefore, the guide portion 21 provided on the guide support body 4 and the guide portions 22 provided above and below the holding body 3 can prevent the holder 3 from being displaced in the vertical direction and can stably slide in the left-right direction. In addition, by maintaining the space 23 between the upper and lower guide portions 21, the holding body 3, that is, the optical device O can be stably slid in the left-right direction. A mounting hole 35 for mounting a helmet mounting attachment 42 to be described later is provided on the upper portion of the guide support 4.

  As described above, the position adjustment mechanism in the left-right direction of the optical apparatus O is supported by adopting the support method by the pressurizing member 27 (spring mechanism) and the sliding method by the fitting structure of the guide portion 21 and the guide portion 22. The body 3 has a simple structure having no locking mechanism, and improves strength and rigidity, and at the same time, speeds up the adjustment operation, improves maintainability, and reduces costs.

  7 is a drawing showing the movable range of the optical device attached to the optical device holding apparatus shown in FIG. 1, wherein (a) is a front view and (b) is a side view. As shown in the drawing, in the optical device O held integrally with the mounting body 2 on the holding body 3, the spherical body portion 6 of the mounting body 2 is held by the spherical seat 9 of the holding body 3 as described above with a holding force. Therefore, if the optical device O is rotated upward with a force equal to or greater than the holding force, the optical device O can be positioned at the upper front portion of the holding body 3. The angle α at which the optical device O is rotated is, for example, about 150 degrees, so that the optical device O is positioned in front of the eyes, and the optical device O is rotated upward and retracted from the eyes. It can be changed to a state in which visibility is ensured.

  Even when the optical device O is rotated in the vertical direction as described above, the force for holding the spherical portion 6 by the spherical seat 9 can be increased as described above, so that the optical device O rotated upward can be stabilized. Can be held. Moreover, even if the optical device O has a wiring for transmitting and receiving signals, the optical device O is further rotated 90 degrees in a state in which the optical device O is rotated upward and retracted so that the wiring is in the horizontal direction. It is also possible to hold the wiring in a state of being turned and turned sideways.

As shown in FIGS. 8 and 9, the optical device holding apparatus 1 according to this embodiment is configured so that the optical device O attached to the attachment body 2 is moved along the guide portion 21 of the guide support body 4 along with the holding body 3 in the left-right direction. Can be slid. This left-right sliding is possible by applying a force greater than the support force. As the slide range, for example, a range in which the optical device O can be positioned in front of the left and right eyes, a range in which the optical device O can be retracted in front of the eyes, and the like can be set.

  The front view of FIG. 8 shows a state of sliding from the state of the solid line located in front of the user's left eye to the state of the two-dot chain line located in front of the right eye. At the time of this sliding, the guide member 22 is adjusted to an appropriate support force by the pressure member 27 with the guide portion 22 engaged with the guide groove 24 of the guide portion 21 as described above, and is provided above and below the holding body 3. Since only the guide portion 22 is slid in a state of being engaged with the guide portion 21 of the guide support body 4, the operator can hold the holding body 3 and slide it stably. In addition, this sliding operation can be performed by holding the holding body 3 with one hand, and the force for holding the spherical portion 6 so that the operation of moving the optical device O up and down as shown in FIG. 7 can be performed with one hand. By adjusting, the operation of adjusting the position of the image display unit of the optical device O in front of the eyes can be easily performed with one hand. As a result, the position of the optical device O can be adjusted with the other hand while working with one hand.

  Further, even when the optical device holding device 1 is mounted and fixed to the helmet 41, the upward rotation region of the attachment body 2 by the attachment body holding portion 8 is expanded to about 150 degrees, so that the optical device O is rotated. By moving it, it is possible to secure the field of view when not in use.

  In addition, the optical device O rotated upward can be rotated upward about the horizontal axis by the spherical seat 9 of the attachment body holding portion 8 in the rotated state. Therefore, it is possible to store the optical device O rotated upward in an arbitrary direction.

  In addition, as described above, the configuration in which the optical device holding device 1 is mounted on the helmet 41 by adjusting each holding force so that the position of the image display unit of the optical device O can be easily adjusted by one-hand operation is provided. As a simple helmet mounting attachment 42 provided with 46, a stable holding state can be maintained.
