Description

  The present invention relates to a wearing tool to which a head mounted display is mounted.

  A head mount display is mounted on the mounting tool disclosed in Patent Document 1. This wearing tool is worn by a band on a helmet, which is an example of a wearing object.

JP, 2018-7050, A

  However, the outer surface of the helmet is often an elliptical shape whose curvature varies depending on the position. Therefore, there is a possibility that the mounting tool is not firmly mounted on the helmet depending on the position where the mounting tool is mounted on the helmet. Therefore, as a result of the mounting position of the mounting device being displaced with respect to the helmet, the head mounted display may be displaced.

  An object of the present invention is to provide a wearing tool that is less likely to shift a mounting position when mounted on a mounting target.

  A mounting tool according to the present invention is a mounting tool to which a head mounted display is mounted, and includes a base portion, a first wall portion extending from the base portion to one side, and the one side longer than the first wall portion. A base portion having a second wall portion extending from the base portion, and an arm arranged on the base portion at a position opposite to the one side with respect to the first wall portion and connected to the head mount display. An arm connecting part that is rotatably connected about a first axis that passes between the first wall part and the second wall part, and a first direction from the second wall part toward the first wall part. A mounting tool fixing part extending from the second wall portion, wherein the mounting tool fixing part is one direction than the first shaft in a predetermined direction orthogonal to the axial direction of the first shaft and the first direction. The first portion arranged on the side and the first axis in the predetermined direction Also, a second portion arranged on the opposite side to the one direction, and between the first portion and the second portion, an opening portion that opens in the axial direction and the first direction, The mounting fixture fixing portion is longer than the arm connecting portion in the predetermined direction.

  According to the above configuration, the mounting target is inserted between the base part, the first wall part, the second wall part, and the mounting fixture fixing part, so that the mounting target is elastically deformed in the first part and the second part. Upon hitting the object, the attachment is attached to the attachment target. Since the wearing equipment fixing part is longer than the arm connecting part in the predetermined direction, the wearing equipment fixing part can stably contact the wearing target. Therefore, a mounting tool that does not easily shift the mounting position when mounted on the target object is realized. This also improves the visibility of the head mounted display.

  The attachment may have a truss shape, and may include a connecting portion that connects the second wall portion and the attachment fixing part. Since the wearing equipment includes the connecting portion, the wearing equipment fixing portion is unlikely to be deformed in the axial direction of the first shaft. The restoring force of the first portion and the second portion when elastically deformed becomes strong. Therefore, the attachment can be firmly attached to the attachment target.

  The mounting device may include a plurality of connecting portions that connect the second wall portion and the mounting device fixing portion and are arranged at intervals along the predetermined direction. Since the wearing equipment includes the plurality of connecting portions, the wearing equipment fixing portion is unlikely to be deformed in the axial direction of the first shaft. Therefore, the attachment can be firmly attached to the attachment target.

  As for the said mounting | wearing tool, the both ends of the said mounting | wearing tool fixing part may be arrange | positioned outside the both ends of the said 2nd wall part in the said predetermined direction. Since both ends of the wearing equipment fixing portion in the predetermined direction are separated from the second wall portion, the wearing equipment fixing portion can be deformed according to the shape of the wearing target object. Therefore, the mounting tool can be stably mounted on the target object.

  In the wearing device, the connecting portion may be arranged on a side opposite to the first direction with respect to the opening, and may be arranged inside both end portions of the wearing device fixing portion in the predetermined direction. Good. Since the connecting portion is separated from both ends of the wearing equipment fixing portion in the predetermined direction, the wearing equipment fixing portion can be deformed according to the shape of the wearing target. Therefore, the mounting tool can be stably mounted on the mounting target.

  In the mounting device, the mounting device fixing portion has a first portion arranged on one side of the opening in the predetermined direction and a direction opposite to the one direction than the opening in the predetermined direction. A state in which the first part and the second part are both inserted into the inside of a pair of facing parts arranged to face each other inside the cap body. Then, it may be pressed against the hat body. Since either the first part or the second part is selectively inserted into the inside of the pair of facing parts, the fitting is fixed with the opening sandwiching a part of the facing parts. Is prevented. Furthermore, the mounting position of the mounting tool on the cap body, which is an example of the mounting target, can be selectively switched between the first portion and the second portion for fixing. Therefore, the usability of the wearing tool is improved.

  In the mounting device, the first wall portion may include an extending portion extending from the base portion to the one side, and a protrusion portion protruding from the extending portion toward the second wall portion. By providing the first wall portion with the protrusion, the first wall portion easily comes into contact with the attachment target. Therefore, the mounting tool can be stably mounted on the target object.

  In the mounting tool, the opening may include a pair of facing surfaces that face each other in the predetermined direction with the first axis interposed therebetween, and the opening may be formed by the pair of facing surfaces. As compared with the case where the opening is arranged on the first direction side with respect to the first axis, a certain degree of easiness of deforming the wearing tool fixing section is secured.

  In the mounting tool, the pair of opposed surfaces may be arranged at positions symmetrical to each other with respect to the first axis. The shape of the non-contact portion at the contact position differs between the first portion that is one side in the predetermined direction with respect to the opening and the second portion that is the opposite side to the one direction with respect to the opening. Even if they are attached, they can always be in contact with each other and can be attached to the attachment target. Therefore, the mounting tool can be stably mounted on the target object.

  In the mounting tool, the base portion may include the base portion, the first wall portion, a claw portion protruding from the base portion to the one side, and a specific portion extending from the first wall portion toward the second wall portion. A first base portion having a wall portion, an arrangement base portion arranged between the base portion and the specific wall portion, and a second wall portion extending from the arrangement base portion to the one side, A second base part to which one base part is detachably attached; and the arrangement base part includes a first plate-shaped part and a second plate-shaped part which are arranged in the predetermined direction and are connected to each other, The first plate-shaped portion and the second plate-shaped portion each include an engagement portion that opens on the opposite side to the one side, and the claw portion engages the engagement of the first plate-shaped portion. Portion and the engaging portion of the second plate-shaped portion are selectively engaged with each other, so that the first base body portion can be mounted on the second base body portion. There. At either position where the claw portion engages with the engagement portion of the first plate-shaped portion or where the claw portion engages with the engagement portion of the second plate-shaped portion, the first base portion is It can be mounted on the base. That is, it is possible to easily switch the mounting position relative to the mounting target without mounting or dismounting the mounting tool that is stably mounted on the mounting target.

  In the mounting device, the first plate-shaped portion and the second plate-shaped portion respectively project from the second base portion on the side opposite to the one side, and are arranged side by side with the engaging portion in between. The convex portion may be provided, and the shortest length from one of the pair of convex portions to the other may be longer than the length of the base portion in the predetermined direction. Since the wearing tool includes the pair of convex portions, the user can easily arrange the base portion at a position where the claw portion can engage with the engaging portion. Therefore, since the positioning is easy and the fixing can be performed stably, the visibility of the head mounted display is enhanced.

  In the mounting tool, the second plate-shaped portion may extend from the first plate-shaped portion toward one side of the predetermined direction and the one side. Even if the mounting position of the first base portion with respect to the second base portion is switched, the head mounted display is difficult to separate from the eyes of the user. Therefore, since the positioning is easy and the head is fixed stably, the visibility of the head mounted display is enhanced.

The insertion portion 39 is pressed against the outer surface of the covering portion 5A of the cap body 5 by the restoring force of the band 6 in the stretched state.

  The arm connecting portion 15 is arranged on the right surface of the base portion 33. In other words, it is arranged on the base portion 33 at a position on the right side of the first wall portion 31. The arm connecting portion 15 is a cylindrical body that opens to the right. The outer diameter of the arm connecting portion 15 is shorter than the length of the second wall portion 32 in the front-rear direction. You. The cylindrical portion 16 is fitted inside the arm connecting portion 15. The first ball joint 19 is fitted inside the cylindrical portion 16. The first shaft 11 of the first ball joint 19 serving as the rotation center of the arm 9 extends in the left-right direction and passes between the first wall portion 31 and the second wall portion 32.

  As shown in FIG. 3, the attachment fixing part 40 extends from the second wall part 32 in an upward direction from the second wall part 32 toward the first wall part 31. The wearing equipment fixing part 40 includes an opening 43, a first part 41, and a second part 42. The opening 43 opens in the left-right direction, which is the axial direction of the first shaft 11, and in the upward direction from the second wall portion 32 toward the first wall portion 31. In this example, the first shaft 11 passes through the inside region of the opening 43, and the lower end of the opening 43 is arranged below the first shaft 11. The opening 43 is formed by a pair of facing surfaces 47 that face each other in the front-rear direction with the first shaft 11 in between. The pair of facing surfaces 47 of this example are arranged at positions symmetrical to each other with respect to the first axis 11.

  The first portion 41 is arranged on the rear side, which is one side in the front-rear direction with respect to the opening 43. The upper end of the first portion 41 is inclined with respect to the up-down direction, and specifically extends upward and leftward. The first portion 41 can bend to the left with the lower end as a fulcrum (arrow D1). The second part 42 is arranged on the front side, which is the side opposite to the one side in the front-rear direction with respect to the opening 43. The second part 42 is symmetrical to the first part 41 in the front-rear direction. That is, the upper end of the second part 42 is inclined with respect to the vertical direction, and the second part 42 can bend to the left with the lower end as a fulcrum (arrow D2). The length in the front-rear direction of each of the first portion 41 and the second portion 42 is shorter than the facing distance between the pair of facing portions 5D of the cap body 5. One of the first portion 41 and the second portion 42 is inserted between the pair of facing portions 5D according to the user's selection (see FIG. 4).

  The rear end of the first part 41 and the front end of the second part 42 are both end parts 48 in the front-rear direction of the wearing tool fixing part 40. Both ends 48 of the wearing equipment fixing part 40 are arranged outside the both ends 32A in the front-rear direction of the second wall 32 in the front-rear direction.

  Hereinafter, the space surrounded by the base body portion 30 and the mounting fixture fixing portion 40 is referred to as a housing space 55. The overhanging portion 5B and the covering portion 5A of the cap body 5 are accommodated in the accommodation space 55. The overhang portion 5B is in contact with each of the first wall portion 31, the front end portion of the second wall portion 32, and the rear end portion of the second wall portion 32. In addition, both the first part 41 and the second part 42 of the wearing tool fixing part 40 are bent to the left with the lower end as a fulcrum. Therefore, both the first portion 41 and the second portion 42 are pressed against the inner peripheral surface of the covering portion 5A by the restoring force against the bending.

  All of the plurality of connecting portions 50 connect the second wall portion 32 and the wearing equipment fixing portion 40. The plurality of connecting portions 50 are arranged at equal intervals along the front-rear direction at the upper and lower positions below the opening 43. The plurality of connecting parts 50 of the present embodiment include a connecting part 50 connected to the first part 41, a connecting part 50 connected to the second part 42, and a connecting part 50 arranged below the opening part 43. Including and In the present embodiment, the plurality of connecting portions 50 are arranged inside the both end portions 32A of the second wall portion 32 in the front-rear direction. That is, the connecting portion 50 arranged on the rearmost side is separated from the rear end portion of the second wall portion 32 to the front side, and the connecting portion 50 arranged on the frontmost side is separated from the front end portion of the second wall portion 32. It's far behind. Further, each connecting portion 50 has a truss shape, and more specifically, has a solid plate shape that is a triangular shape in a front view. The connecting portion 50 has a surface 50 </ b> A facing the extending portion 34 of the first wall portion 31. The surface 50A is formed in a flat shape.

  A method of mounting the wearing tool 1 on the cap body 5 will be described with reference to FIGS. 3 and 4. Before the wearing of the wearing tool 1, one end of the arm 9 (see FIG. 1) is connected to the arm connecting portion 15, and the HMD 10 (see FIG. 1) is connected to the other end of the arm 9.

  The user pinches both the first part 41 and the second part 42 to bend them to the left (arrows D1 and D2 in FIG. 3). The user inserts the bent first portion 41 between the pair of facing portions 5D from below. At this time, one of the pair of facing portions 5D is inserted into the opening 43. At the same time, the user causes the overhanging portion 5B and the covering portion 5A to enter the accommodation space 55 from above. A portion of the second wall portion 32 on the right side of the plurality of connecting portions 50 contacts the overhanging portion 5B from below, and the protrusion 35 contacts the overhanging portion 5B from above (see FIG. 5). . When the user releases his / her hand from the first portion 41 and the second portion 42, the first portion 41 and the second portion 42 are pressed against the inner peripheral surface of the covering portion 5A by their restoring forces. Therefore, the mounting tool 1 is mounted on the cap body 5 in a state in which the second wall portion 32 and the protruding portion 35 are in contact with the overhanging portion 5B. At this time, since the first portion 41 is inserted between the pair of facing portions 5D, the movement of the wearing tool 1 in the front-rear direction is restricted. Therefore, the positional displacement of the wearing tool 1 in the front-back direction is suppressed. The user inserts the band 6 into the insertion hole 39B through the hole portion 39A of the insertion portion 39. By the band 6 pressing the insertion part 39 against the covering part 5A, the posture of the wearing tool 1 is further stabilized.

  The user can insert the second portion 42 into the pair of facing portions 5D instead of the first portion 41 (not shown). Since the mounting method at this time is the same as the above-mentioned method, detailed description thereof will be omitted. Even when the second portion 42 is inserted into the pair of facing portions 5D, the other of the pair of facing portions 5D is inserted into the opening 43, and the overhanging portion 5B includes the protrusion 35 and the second wall 32. Contact with. Furthermore, the protrusion 35 and the second wall 32 contact the overhanging portion 5B, and the first portion 41 and the second portion 42 both press the covering portion 5A.

  In the following description, the mounting position of the mounting device 1 when the first portion 41 is inserted into the pair of facing portions 5D is referred to as a "first mounting position" (see FIG. 4), and the second portion 42 is a pair of facing portions. The mounting position of the mounting tool 1 when it is inserted into the portion 5D is referred to as a "second mounting position" (not shown).

  When the mounting tool 1 is mounted in the first mounting position, the HMD 10 is easily arranged on the front side with respect to the left eye of the user. Therefore, the user can easily visually recognize the image light emitted from the HMD 10. On the other hand, when the mounting tool 1 is mounted in the second mounting position, the HMD 10 is arranged on the right rear side as compared with the case where the mounting tool 1 is mounted in the first mounting position. Therefore, the HMD 10 is likely to be arranged outside in the left-right direction with respect to the left eye of the user. Therefore, the user can visually recognize the image light emitted from the HMD 10 while visually recognizing the front scene. Therefore, the user can switch the mounting position of the mounting device 1 between the first mounting position and the second mounting position according to the purpose of use of the HMD 10.

  Regardless of the mounting position of the mounting device 1, the second wall portion 32 and the protrusion 35 contact the overhanging portion 5B from the outer side in the vertical direction, so that the positional displacement of the mounting device 1 in the vertical direction is suppressed. Further, regardless of the mounting position of the mounting device 1, one of the first part 41 and the second part 42 is inserted between the pair of facing parts 5D, and the positional deviation of the mounting device 1 in the front-rear direction is suppressed. It Further, the first portion 41 and the second portion 42 are pressed against the covering portion 5A, so that the positional deviation of the wearing tool 1 in the vertical direction and the front-back direction is suppressed. Therefore, even when the user adjusts the position by moving the HMD 10 back and forth, left and right, and up and down around the first axis 11 and the second axis (not shown), the wearing tool 1 is unlikely to be displaced. . Therefore, the HMD 10 does not move excessively due to the position shift of the wearing tool 1 when the user adjusts the position. Therefore, the user can enhance the visibility of the HMD 10 by easily and properly performing the position adjustment of the HMD 10.

  As described above, when the mounting tool 1 is mounted at the first mounting position or the second mounting position, the first portion 41 or the second portion 42 is inserted into the pair of facing portions 5D. At this time, the overhanging portion 5B and the covering portion 5A of the cap body 5 enter the accommodation space 55, and the elastically deformed first portion 41 and second portion 42 both press the covering portion 5A. As a result, the mounting tool 1 is mounted on the cap body 5. The outer diameter of the arm connecting portion 15 is shorter than the length of the second wall portion 32 in the front-rear direction. In other words, the second wall portion 32 is longer than the arm connecting portion 15 in the front-back direction. Therefore, at least two portions of the second wall portion 32 that are separated from each other in the front-rear direction can stably contact the cap body 5 from the lower side. Furthermore, the lower end of the protrusion 35 can contact the overhanging portion 5B from above. This defines the position of the wearing tool 1 with respect to the overhanging portion 5B, so that the wearing tool 1 is stably mounted. Therefore, the wearing tool 1 in which the wearing position is less likely to shift when it is worn on the cap body 5 is realized. Alternatively, the cap body 5 may not have the facing portion 5D. Specifically, the second wall portion 32 and the protrusion 35 contact the overhanging portion 5B from the outer side in the vertical direction, so that the positional displacement of the wearing tool 1 in the vertical direction is suppressed. Further, since the first portion 41, the second portion 42, and the first wall portion 31 are in contact with each other so as to sandwich the covering portion 5A, displacement of the wearing tool 1 in the left-right direction is suppressed. The frictional force generated by the contact between the second wall portion 32 and the projection portion 35 with the overhanging portion 5B as described above, and the first portion 41, the second portion 42, and the first wall portion 31 are covered as described above. The frictional force generated by the contact with the portion 5A suppresses the positional deviation of the wearing tool 1 in the front-rear direction. Therefore, the wearing tool 1 in which the wearing position is unlikely to be displaced when being worn on the cap body 5 which is an example of the wearing object is realized. The visibility of the HMD 10 is also improved due to the effect of preventing positional displacement.

  All of the plurality of connecting portions 50 connect the second wall portion 32 and the wearing equipment fixing portion 40. Therefore, both the first portion 41 and the second portion 42 are unlikely to bend to the left along the left-right direction that is the axial direction of the first shaft 11. Therefore, when the wearing tool 1 is worn on the cap body 5, the first part 41 and the second part 42, which the user releases the hand, firmly press the covering part 5A. Therefore, the wearing tool 1 can be firmly attached to the cap body 5. In particular, in a case where the mounting position of the mounting device 1 is used with a low frequency of switching, the HMD 10 is less likely to be displaced due to the strong mounting of the mounting device 1, and the visibility of the HMD 10 is improved.

  A plurality of connecting portions 50 are arranged along the front-rear direction. Since the wearing equipment 1 includes the plurality of connecting portions 50, the wearing equipment fixing portion 40 is more difficult to bend to the left along the axial direction of the first shaft 11. Therefore, the wearing tool 1 can be firmly attached to the cap body 5. More specifically, the wearing tool 1 transmits the force applied in the vertical direction to the overhanging portion 5B of the cap body 5 mainly by the protrusion 35. Then, when the HMD 10 is in a state of being connected to the wearing tool 1, a moment force for pressing the wearing tool fixing portion 40 to the right is generated with the position where the protrusion 35 and the cap body 5 contact each other as the rotation center. At this time, the wearing tool fixing part 40 is strongly pressed against the inner peripheral surface of the covering part 5A, so that a stronger force is applied to the vicinity of the connecting part 50, and the wearing tool fixing part 40 is easily bent. Even in this case, the connecting part 50 suppresses the bending of the wearing tool fixing part 40, particularly in the vicinity of the connecting part 50, and the overhanging part 5B comes out of the accommodation space 55, and the wearing tool 1 due to a large bending. It is possible to suppress the occurrence of backlash.

  Both ends 48 of the wearing equipment fixing part 40 are arranged outside the both ends 32A of the second wall part 32 in the front-rear direction. Since the both end portions 48 are separated from the both end portions 32A, they are easily bent toward the left side. Therefore, when the first portion 41 or the second portion 42 is pressed against the covering portion 5A, both end portions 48 of the mounting device fixing portion 40 can be deformed into a shape following the covering portion 5A. Therefore, since the wearing tool fixing part 40 easily comes into contact with the covering part 5A, the wearing tool 1 can be stably worn on the cap body 5.

  The plurality of connecting portions 50 are arranged on the inner side in the front-rear direction with respect to both end portions 32A of the second wall portion 32. In other words, the plurality of connecting portions 50 are arranged inside the both end portions 48 of the wearing equipment fixing portion 40 in the front-back direction. Since the connecting portion 50 is separated from both end portions 48 of the wearing equipment fixing portion 40, the both end portions 48 of the wearing equipment fixing portion 40 can be deformed into a shape following the shape of the covering portion 5A. Therefore, the wearing tool fixing portion 40 easily contacts the covering portion 5A, so that the wearing tool 1 can be stably worn on the cap body 5.

  The user selectively inserts either the first portion 41 or the second portion 42 into the inside of the pair of facing portions 5D. Since the wearing tool 1 is fixed in a state in which the opening 43 sandwiches one of the facing portions 5D, the wearing tool 1 is prevented from being displaced. Further, the mounting position of the mounting tool 1 on the cap body 5 can be selectively switched between the first mounting position and the second mounting position. Therefore, the usability of the wearing tool 1 is improved.

  The first wall portion 31 includes a protrusion 35. The lower end of the protrusion 35 is curved downward and is long in the front-rear direction. Therefore, the protrusion 35 is likely to come into line contact with the overhanging portion 5B. Since the overhanging portion 5B easily contacts between the protrusion 35 and the second wall portion 32, the mounting tool 1 can be stably mounted on the cap body 5.

  The pair of opposed surfaces 47 forming the opening 43 oppose each other with the first shaft 11 in between. That is, the opening 43 is formed not only on the upper side of the first shaft 11 but also on the lower side of the first shaft 11. Therefore, the opening 43 is larger than when the opening 43 is arranged only above the first shaft 11. Thereby, a certain degree of flexibility of the first part 41 and the second part 42 is ensured.

  The pair of opposed surfaces 47 are arranged at positions symmetrical to each other with the first axis 11 in between. The first part 41 and the second part 42 may always be pressed against the covering part 5A even if the cap body 5 has different curvatures at the positions of the covering part 5A where the first part 41 and the second part 42 are in contact with each other. it can. Therefore, the wearing tool 1 can be stably mounted on the cap body 5.

  In the above description, the left side is an example of "one side" of the present invention. The upward direction is an example of the "first direction" in the present invention. The front-back direction is an example of the “predetermined direction” in the present invention. The backward direction is an example of the “unidirectional” in the present invention. The left-right direction is an example of the “axial direction” in the present invention.

  The wearing tool 1 can be variously modified. The cap body 5 may be, for example, a cap formed of cloth instead of the industrial helmet. The wearing tool 1 may be attachable to another wearing target instead of the hat body 5. The opening 43 may be formed only on the upper side of the first shaft 11. The pair of facing surfaces 47 may be asymmetric with respect to the first axis 11. The first part 41 and the second part 42 may be asymmetric in the front-rear direction.

  The wearing tool 1 may include a single connecting portion 50 instead of including the plurality of connecting portions 50. The single connecting part 50 may be long in the front-rear direction. In this case, the single connecting portion 50 connects the first portion 41 and the second wall portion 32, and also connects the second portion 42 and the second wall portion 32. The connecting portion 50 does not have to be a truss shape. For example, the surface 50 </ b> A may have a circular arc shape that curves toward the connecting position between the mounting device fixing section 40 and the second wall section 32 instead of the flat surface shape. Both ends 48 of the wearing equipment fixing part 40 and both ends 32A of the second wall part 32 may be arranged at the same position in the front-rear direction. In this case, the connecting portion 50 may connect the front end portion of the wearing equipment fixing portion 40 and the front end portion of the second wall portion 32, or the rear end portion of the wearing equipment fixing portion 40 and the second wall portion 32. You may connect with the rear end part.

  With reference to Drawing 5-Drawing 7, wearing tool 2 which is a 2nd example of the present invention is explained. The same members as those in the first embodiment are designated by the same reference numerals in the drawings, and detailed description thereof will be appropriately omitted. Like the wearing tool 1, the wearing tool 2 is worn on the cap body 5.

  Like the wearing tool 1, the wearing tool 2 includes a base portion 30, an arm connecting portion 15, a wearing tool fixing portion 40, and a plurality of connecting portions 50. The wearing tool 2 is different from the wearing tool 1 in that the wearing tool 2 includes an electrical component section 60 instead of the insertion section 39 (see FIG. 2).

  The configuration of the electrical component section 60 will be described in detail. The electrical component section 60 holds a device for operating the HMD 10. Specifically, the electrical component unit 60 holds the battery 91, the control box 92, and the cable 93.

  As shown in FIG. 5, the electrical component section 60 includes a support plate 52, a cover 59, an upper protrusion 51, a lower protrusion 53 (see FIG. 6), and a pair of protrusions 61 (see FIG. 6). The support plate 52 is a plate that extends along the open end of the covering portion 5A and is arranged above the first wall portion 31.

  The support plate 52 is provided with a pair of insertion portions 78 (see FIG. 7) and a pair of protrusions 61 (see FIG. 6). The pair of insertion portions 78 are arranged on the end surface of the support plate 52 on the side of the cap body 5 and are arranged along the longitudinal direction of the support plate 52. Each of the pair of insertion portions 78 includes a hole portion 78A that opens in the left-right direction and an insertion hole 78B that opens in the longitudinal direction of the support plate 52. The hole portion 78A has a shape through which the band 6 can pass. The band 6 that has passed through the insertion hole 78B is arranged in the insertion hole 78B. The band 6 presses the pair of insertion portions 78 against the outer surface of the covering portion 5A. The pair of protrusions 61 protrude from the support plate 52 toward the right side. The cover 59 (see FIG. 5) is a box-shaped body that covers the pair of protrusions 61 and a control box 92 described below, and is attached to the support plate 52.

  As shown in FIG. 6, both the upper protruding portion 51 and the lower protruding portion 53 protrude from the support plate 52 toward the right side, and extend along the longitudinal direction of the support plate 52. The lower protrusion 53 is longer than the upper protrusion 51. The upper protruding portion 51 and the lower protruding portion 53 face each other in the vertical direction with the cover 59 (see FIG. 5) interposed therebetween. An insertion portion 53 </ b> A that opens in the vertical direction is provided on the front portion of the lower protruding portion 53.

  As shown in FIGS. 6 and 7, a battery support portion 65 is provided on the upper protruding portion 51. The battery support portion 65 includes a plate portion 63 and a pair of curved portions 64. The plate portion 63 projects upward from the upper projecting portion 51. The pair of bending portions 64 protrudes from the upper protruding portion 51 toward the right side, and is curved in a semi-circular shape toward the lower side. The pair of bending portions 64 are arranged in the front-rear direction, and the battery 91 is fitted therein. As a result, the battery support portion 65 supports the battery 91.

  As shown in FIG. 6, a portion of the support plate 52 that is behind the upper protruding portion 51 is the support portion 57. The support portion 57 is provided on the rear side of the upper protruding portion 51. The support portion 57 faces the control box 92 formed in a rectangular parallelepiped shape from the left side. The support portion 57 is provided with a pair of upper holding portions 73 and a pair of lower holding portions 74. Both the upper holding portion 73 and the lower holding portion 74 are formed in a hook shape. Specifically, the pair of upper holding portions 73 protrudes from the upper portion of the support portion 57 to the right side, and further bends in a direction toward each other, and the pair of lower holding portions 74 protrudes from the lower portion of the support portion 57 to the right side. , And then bend toward each other. The control box 92 is inserted between the pair of upper holding portions 73 and between the pair of lower holding portions 74. The upper holding portion 73 and the lower holding portion 74 prevent the control box 92 from coming off. Therefore, the control box 92 is held.

  The control box 92 and the battery 91 are connected by a cable 95. As a result, the battery 91 can supply power to the control box 92. A cable 93 is drawn out from the control box 92. The cable 93 is wound around the pair of protrusions 61, passes through the insertion portion 53A, and is drawn out to the lower side. The wound cable 93 is covered with a cover 59 (see FIG. 5). The cable 93 pulled out downward from the insertion portion 53A travels along the arm 9 and is inserted into the insertion port 10A of the HMD 10. This allows the control box 92 to supply power to the HMD 10 and transmit various signals.

  As shown in FIG. 5, the wearing tool 2 further includes a hook 77. The hook 77 extends from the rear portion of the lower protruding portion 53 (see FIG. 6) to the lower side of the cap body 5, and further protrudes toward the upper side and the inner side of the cap body 5. When the mounting tool 2 is mounted at the first mounting position or the second mounting position, the rear portion of the mounting tool 2 may sometimes float due to the weight of the battery 91 and the HMD 10 (arrow E1). Even in this case, since the hook 77 comes into contact with the overhanging portion 5B from below, the lifting of the rear portion of the wearing device 2 is suppressed. Therefore, the wearing tool 2 can be stably worn on the cap body 5.

  A mounting tool 3 according to a third embodiment of the present invention will be described with reference to FIGS. In addition, about the structure similar to the wearing tool 1, the same code | symbol is attached in drawing and detailed description is abbreviate | omitted suitably.

When the first base portion 110 is mounted at the second specific mounting position, the first wall portion 131 contacts the second plate-shaped portion 222 from above and extends to the left side of the second plate-shaped portion 222. Extend. At this time, the specific wall portion 137 faces the base portion 133 with the second plate-shaped portion 222 interposed therebetween. Further, the base portion 133 comes into contact with the second plate-shaped portion 222 from the right side between the pair of convex portions 261, and the claw portion 136 engages with the engaging portion 229 of the second plate-shaped portion 222 to operate. The portion 139 is arranged below the second plate-shaped portion 222.

  The insertion holding portion 270 will be described with reference to FIG. 8. The insertion holding portion 270 is a plate-shaped member that is separate from the base portion 130. The insertion holding portion 270 includes a connecting portion 271, an insertion portion 239, and a cable holding portion 250. The connecting portion 271 is arranged between the pair of supporting portions 257, and is arranged above the passage hole 299. The connecting portion 271 includes a pair of fitting portions (not shown). The pair of fitting portions protrude outward in the front-rear direction and are formed in a columnar shape. By inserting the pair of fitting portions into the pair of support holes 257A, the insertion holding portion 270 is supported by the pair of support portions 257.

  The insertion portion 239 is formed in a substantially C shape in a front view, and is arranged right above the second wall portion 232 (see FIG. 11). The lower right part of the insertion part 239 is connected to the left part of the connection part 271. The insertion portion 239 includes a hole portion 239A that opens in the left-right direction and an insertion hole 239B that opens in the front-rear direction. The hole portion 239A has a shape through which the band 6 (see FIG. 1) can pass. The band 6 that has passed through the hole portion 239A is arranged in the insertion hole 239B.

The amount of opening of the first opening 251 in the left-right direction increases or decreases as the cable holding portion 250 is deformed in the left-right direction. The second opening 252 is provided below the first opening 251. The cable holding unit 250 holds the cables 93 by the second openings 252 bundling the cables 93. One end of the held cable 93 is connected to the insertion port 10A of the HMD 10 (see FIG. 6). In the third embodiment, the other end of the cable 93 is connected to the control box 92 (see FIG. 6) held at the rear part of the cover 5A. In the third embodiment, the illustration of the control box 92 is omitted.

  A method of changing the mounting position of the first base 110 will be described with reference to FIGS. 8, 9, and 11. Before changing the mounting position, the first base 110 is mounted at the first specific mounting position (see FIG. 8).

  The user hooks the finger on the operation unit 139 and pushes the base 133 to the right. The base 133 is bent toward the right side with the upper end as a fulcrum (arrow F1 in FIG. 8). As a result, the claw portion 136 disengages from the engaging portion 229 of the first plate-shaped portion 221, and the first base body portion 110 can move upward. The user is. The first base 110 is moved upward along the pair of protrusions 261. The first wall portion 131 and the specific wall portion 137 pass through the passage hole 299 and move to the upper right with respect to the first plate-shaped portion 221 (not shown). As a result, the first base 110 is separated from the second base 200.

  The user causes the base 133 to enter between the upper portions of the pair of convex portions 261 of the second plate-shaped portion 222 while arranging the specific wall portion 137 on the left side of the second plate-shaped portion 222 (Fig. 11). At this time, the user hooks his / her finger on the operation portion 139 and urges it to the right side, and the base portion 133 is bent to the right side with the upper end portion as a fulcrum. The user moves the base 133 downward along the pair of protrusions 261 with the claw 136 pressed against the right surface of the second plate-shaped portion 222 above the engaging portion 229. The claw portion 136 that has descended to the same vertical position as the engaging portion 229 of the second plate-shaped portion 222 enters the engaging portion 229 by the restoring force of the base portion 133 in the bent state. As a result, vertical movement of the base 133 is restricted. At this time, the first wall portion 131 contacts the upper end of the second plate-shaped portion 222, and the first base body portion 110 is mounted at the second specific mounting position.

  The method of changing the mounting position of the first base 110 from the second specific mounting position to the first specific mounting position is similar to the above, and thus the detailed description of the method is omitted. The method of inserting the band 6 into the insertion portion 239 is also the same as that in the first embodiment, and therefore will be omitted.

  As described above, in the wearing tool 3 of the third embodiment, the first base body portion 110 can be mounted on the second base body portion 200 at either the first specific mounting position or the second specific mounting position. Becomes That is, the relative mounting position with respect to the cap body 5 can be easily switched without attaching or detaching the mounting tool 3 that is stably mounted on the cap body 5, which is an example of the mounting target.

  The first plate-shaped portion 221 and the second plate-shaped portion 222 each include a pair of convex portions 261. When the mounting position of the first base 110 is changed, the base 133 moves along the pair of protrusions 261. That is, the pair of convex portions 261 guide the downward movement of the base 133. This makes it easier for the user to arrange the base 133 at a vertical position where the claw 136 can engage with the engaging portion 229. Therefore, since the mounting tool 3 can be easily positioned and the mounting tool 3 can be stably fixed, the visibility of the HMD 10 is enhanced.

  The second plate-shaped portion 222 extends from the first plate-shaped portion 221 toward the front side and the left side. The change in the position of the HMD 10 when the mounting position of the base 133 is switched between the first specific mounting position and the second specific mounting position is that the second plate-shaped portion 222 extends from the first plate-shaped portion 221 to the front side and the right side. It is smaller than that of the embodiment. Therefore, even if the mounting position of the base 133 with respect to the second base portion 200 is switched, the HMD 10 is difficult to separate from the eyes of the user. Therefore, the positioning of the wearing tool 3 is easy, and the wearing tool 3 is stably fixed, so that the visibility of the HMD 10 is enhanced.

  The wearing tool 3 is not limited to the above embodiment. The engaging portion 229 may be open to the side opposite to the second wall portion 232, and may be, for example, a recess opening to the right. The convex portion 261 may have a hemispherical shape, for example, instead of extending linearly in the vertical direction. The operation portion 139 may be a recessed portion that is recessed rightward from the left surface of the base 133. The operation unit 139 may be formed separately from the base 133.

  The second base portion 200 may include a third plate-shaped portion (not shown). The third plate-shaped portion extends from the rear end of the first plate-shaped portion 221 to the rear side and the left side, for example. Similar to the first plate-shaped portion 221, the third plate-shaped portion may include the engaging portion 229 and the pair of convex portions 261. As a result, the first base portion 110 can be attached to the third plate-shaped portion.
