  A foldable stereoscopic viewer is convenient for carrying or storing. However, in Patent Document 2, the assembly procedure of the stereoscopic viewer is complicated, so that it is not suitable for frequent assembly or disassembly. Also, when disassembled, a thick paper such as cardboard is simply folded, so it is difficult to say that it is suitable for carrying. Furthermore, in Patent Document 2, since the portable display device is stored in a region (pocket portion) of a predetermined size, the stereoscopic viewer may not be used depending on the size of the portable display device.

  Moreover, in patent documents 3-5, since only a part of portable display apparatus is hold | maintained at a stereoscopic viewer, it is unstable. Therefore, the user must always hold both the stereoscopic viewer and the portable display device while watching the content, and needs to be careful.

  Moreover, in patent document 2, there exists a possibility that external light may enter in a housing | casing from the clearance gap of the assembled housing | casing. In Patent Documents 3 to 5, the portable display device is exposed when the portable display device is attached to the stereoscopic viewer. In other words, in Patent Documents 2 to 5, when ambient light enters the user's field of view, there is a risk that the sense of immersion in the content being watched will be reduced.

  Further, in Patent Document 5, since the lens is exposed even when the stereoscopic viewer is folded (see FIG. 13 of Patent Document 5), the lens may be damaged when it is carried. In addition, when the lens is exposed, it is necessary to pay attention to the storage location such as avoiding direct sunlight.

  The present invention has been made in view of the above, and is easy to carry, can be easily and quickly used when necessary, can stably hold a portable display device, and has various sizes.

As shown in FIGS. 1 and 2, the stereoscopic viewer 1 includes a main body 10 to which two lenses 30 are attached, and a cover 20 that is wound around at least a part of the outer surface of the main body.

  In the following, the direction in which the two lenses 30 are arranged is referred to as the left-right direction (first direction), and the direction orthogonal to the left-right direction in the plane in which the lenses 30 are arranged is referred to as the up-down direction (second direction). . Further, in the vertical direction, the side on which the nose pad 112 is provided is referred to as the lower side, and the opposite side is referred to as the upper side.

  A first end portion (hereinafter referred to as a fixed side end portion 201) of the cover 20 is fixed to the main body 10, and a second end portion (hereinafter referred to as a slide side end portion 202) opposite to the first end portion. ) Is slidably attached to the main body 10. The stereoscopic viewer 1 has a structure that is opened and closed by sliding the slide side end portion 202 of the cover 20. That is, when the slide side end portion 202 of the cover 20 is slid upward (see FIG. 1), the two lenses 30 are exposed and the main body 10 expands in the thickness direction so that the stereoscopic viewer 1 can be used. . Further, when the slide side end portion 202 of the cover 20 is slid downward (see FIG. 2), the two lenses 30 are covered with the cover 20 and the main body 10 is closed in the thickness direction to be in the housed state.

  FIG. 3 is a front view showing the main body 10 of the stereoscopic viewer 1 shown in FIG. FIG. 4 is a rear view showing the main body 10. FIG. 5 is a rear view showing a state in which the holding sheet is attached to the main body 10. FIG. 6 is a bottom view showing the main body 10. 7 is an end view taken along the line AA in FIG. FIG. 8 is a perspective view showing the main body 10 and shows a state in which the main body 10 is opened. FIG. 9 is a perspective view of the main body 10 and shows a storage state of the main body 10.

  As shown in FIGS. 3 to 9, the main body 10 includes a front plate member (first plate-like member) 11 in which two lenses 30 that the user peeks with the left and right eyes are fitted, and the front plate member 11. It has a back plate member (second plate-like member) 12 disposed so as to face each other, and a connecting portion 13 that connects the front plate member 11 and the back plate member 12. The main body 10 may further include side walls 14 and 15 provided on the front plate member 11 and the back plate member 12, respectively.

  In the present embodiment, the front plate member 11 and the back plate member 12 are integrally formed with the side walls 14 and 15 by injection molding using plastic as a material. However, the material and manufacturing method of the front plate member 11 and the back plate member 12 are not limited to this.

  As shown in FIG. 3, the main surface of the front plate member 11 has a substantially rectangular shape. On the lower side of the front plate member 11 (see the lower end region 11a), a concave portion 111 that is curved on the inner peripheral side is formed, and a nose pad 112 that is smoothly curved along the concave portion 111 is provided. .

  Two guide rails 113 are formed in parallel to each other on the outer sides of the two lenses 30 in the front plate member 11. The guide rail 113 is a groove that penetrates the front plate member 11 and is provided to slide the slide side end portion 202 of the cover 20. The vertical range in which the guide rail 113 is formed is at least a range from the upper end portion to the lower end portion of the two lenses 30. Preferably, on the lower side of the lens 30, the guide rail 113 may be extended to a position that overlaps the fixed-side end 201 when the cover 20 is attached to the main body 10. This is because when the stereoscopic viewer 1 is stored, the fixed-side end 201 and the slide-side end 202 of the cover 20 can be closed without a gap. In addition, on the upper side of the lens 30, the guide rail 113 may be extended about several millimeters to several centimeters above the upper end of the lens 30 so that it does not get in the way when the user brings his eyes close to the lens 30.

  In the lower end region 11 a of the front plate member 11, a through hole 115 is formed that is used when the fixed side end 201 of the cover 20 is fixed to the main body 10.

  In the present embodiment, in order to suppress reflection of light around the lens 30, a beveled unevenness is formed on a part of the outer surface 110 of the front plate member 11. However, the aspect of the outer surface 110 is not limited to this. For example, the entire outer surface 110 may be smooth and flat, or the entire surface of the outer surface 110 may be frosted, or a stripe pattern or checkered pattern in which smooth portions and frosted portions are alternately arranged. Etc. may be applied to the outer surface 110.

  As shown in FIG. 4, the main surface of the back plate member 12 has a substantially rectangular shape like the front plate member 11. In the present embodiment, the concave portion 120 is formed on the lower side of the back plate member 12 (see the lower end region 12a) in the same manner as the front plate member 11, but the concave portion 120 is not essential. When the recess 120 is provided, the shape of the lower end region 11a of the front plate member 11 and the lower end region 12a of the back plate member 12 are aligned, so that the lower end regions 11a and 12a are closed when the main body 10 is closed. There is an advantage that the end surfaces of the main body 10 can be brought into contact with each other and the bottom surface of the main body 10 can be closed.

  In addition, the back plate member 12 is formed with an opening 121 that exposes at least a part of the display screen when the surface on which the display screen of the portable display device is provided contacts. In the present embodiment, a frame 122 that divides the opening 121 into two regions is provided at substantially the center in the left-right direction of the opening 121. By providing such a frame 122, even when the external size of the portable display device is smaller than the opening 121, the portable display device does not enter the opening 121, and the display screen is used as a back plate member. 12 can be maintained.

  A fixing portion 123 for attaching the holding sheet 40 is formed near the upper and lower end portions of the back plate member 12. The holding sheet 40 is a sheet member formed of a flexible and stretchable material such as a vinyl or rubber sheet, and is used to hold the portable display device firmly on the main body 10. As shown in FIG. 5, openings 401 are formed in upper and lower end regions of the holding sheet 40, and the holding sheet 40 is attached to the back plate member 12 by hanging these openings 401 on the fixing portion 123. Attach to. At least one of the left and right ends of the holding sheet 40 (both in the present embodiment) is open to the back plate member 12 for taking in and out the portable display device. Although it is not essential to use the holding sheet 40, when the holding sheet 40 is used, the portable display device can be held more stably with respect to the main body 10, and displacement can be prevented. There are advantages. Thereby, the freedom degree of material selection of the cover 20 can be expanded.

  In addition, the shape of the main surface of the front plate member 11 and the back plate member 12 is a shape that can hold the two lenses, can contact the portable display device, and can wind the cover 20. The shape is not limited to a substantially rectangular shape. For example, an oval shape in which the left and right ends are semicircular may be used.

  As shown in FIG. 6, the connecting portion 13 has a foldable hinge structure and is provided between the front plate member 11 and the back plate member 12 to connect the front plate member 11 and the back plate member 12. To do. Specifically, the connecting portion 13 includes two blade portions 131 and 132, and a pin 133 that is inserted into a shaft tube provided on one end side of each of the blade portions 131 and 132 and connects the blade portions 131 and 132 to each other. A pin 134 that is inserted into a shaft tube provided on the other end side of the blade portion 131 and a shaft tube provided on the back surface of the front plate member 11 to connect the blade portion 131 and the front plate member 11, and the blade portion 132 A shaft cylinder provided on the other end side and a pin 135 inserted through a shaft cylinder provided on the back surface of the back plate member 12 to connect the blade portion 132 and the back plate member 12 are included.

  A torsion spring 136 that urges the blade 131 in a direction to open with respect to the front plate member 11 is attached to the pin 134. Further, a torsion spring 137 that urges the blade portion 132 in a direction to open with respect to the back plate member 12 is attached to the pin 135. Thereby, while the connecting portion 13 is folded, the front plate member 11 and the back plate member 12 are biased in a direction away from each other. Therefore, when the cover 20 is opened, the front plate member 11 and the back plate member 12 are separated semi-automatically, and the main body 10 expands in the thickness direction.

  The blade portions 131 and 132 are provided with stoppers 138 and 139 for maintaining the angle formed between them (the angle on the outside of the main body 10) below a predetermined angle (an angle of less than 180 ° at the maximum). As a result, even if the main body 10 reaches the maximum swelled state, the blade portions 131 and 132 do not open in a straight line, so that the connecting portion 13 can be easily folded even with a small force. It becomes possible to contract smoothly.

  As shown in FIGS. 7 to 9, the lower end region 11 a and the upper end region 11 b of the front plate member 11, and the lower end region 12 a and the upper end region 12 b of the back plate member 12 are formed of the main body 10. Curved towards the inside. Thereby, when the main body 10 is contracted in the thickness direction, the upper end surfaces of the front plate member 11 and the back plate member 12 and the lower end surfaces come into contact with each other, and the front plate member 11 and the back plate member 12 are brought into contact with each other. The gaps on the top and bottom surfaces are closed, and the main body 10 has a thin box shape as a whole (see FIG. 9). Further, by bending the upper end regions 11b and 12b of the front plate member 11 and the back plate member 12 inward, there is an advantage that the movement of the cover 20 can be made smooth when the cover 20 is slid.

  However, the lower end regions 11a and 12a and the upper end regions 11b and 12b of the front plate member 11 and the back plate member 12 may be left flat without being curved. Alternatively, a ceiling member or a bottom member may be separately connected to the upper end and the lower end of the front plate member 11 and the back plate member 12.

  The side wall 14 is provided integrally with the front plate member 11, and the side wall 15 is provided integrally with the back plate member 12. Here, as shown in FIG. 8, when the main body 10 is open, the side surfaces of the main body 10 are shielded from light by the blade portions 131 and 132. In addition to this, by providing the side walls 14 and 15, the gaps between the blade portions 131 and 132 and the front plate member 11 and the back plate member 12 can be shielded from the outside. Intrusion of light can be further suppressed.

  As shown in FIG. 9, when the main body 10 is contracted, the end surface of the side wall 14 abuts on the back plate member 12, and the distance between the front plate member 11 and the back plate member 12 is maintained at a predetermined distance. . Thereby, it can prevent that the back surface of the lens 30 contacts the backplate member 12, and is damaged. Further, since the gap between the front plate member 11 and the back plate member 12 is closed by the side wall 14, it is possible to prevent foreign matter from entering the main body 10.

  In the present embodiment, the surface of the side wall 14 that becomes the outer side when the main body 10 is contracted is planar, but a concave portion or a protrusion for a handle may be provided on a part of this surface.

  Further, according to the present embodiment, since the lens 30 is covered with the cover 20 in the accommodated state of the stereoscopic viewer 1, the lens 30 can be protected even while the stereoscopic viewer 1 is being carried.

  Moreover, according to this embodiment, since the main body 10 and the cover 20 are comprised by the separate member, the design property of the stereoscopic viewer 1 can be improved by changing the material and pattern of the cover 20.

  Moreover, according to this embodiment, since the cover 20 can be easily removed from the main body 10, the user can remove the cover 20 by himself and perform care such as washing. Therefore, the stereoscopic viewer 1 can be used cleanly.

  Moreover, according to this embodiment, since the cheek rest 21 is provided at the fixed-side end portion 201 of the cover 20, the user's feeling of use can be improved and adhesion of sebum or the like to the cover 20 can be suppressed. Furthermore, it is possible to suppress the intrusion of light from below between the stereoscopic viewer 1 and the user's face.

  In the above embodiment, the cover 20 is formed of a flexible material, but the material of the cover 20 is not limited to this. For example, the cover 20 may be formed of a member having a hook-like structure in which natural materials such as bamboo and cocoons cut into long and narrow shapes, plastics formed into an elongated rod shape, and the like are knitted with yarn. In this case, the cover can be wound around the main body 10 by arranging a rod-like member in parallel with the left-right direction of the main body 10. In short, any sheet-like member that can be deformed at least in the direction orthogonal to the left-right direction of the main body 10 can be used as the cover 20. In the case where the cover 20 is formed by a member having a bowl-like structure, the guide rod 22 is not necessarily provided.

  Further, in the above-described embodiment, a case has been described in which content stored in advance in the portable display device 2 is viewed using the stereoscopic viewer 1, but a camera built in the portable display device 2 is used. It is also possible to perform stereoscopic viewing. In this case, an opening may be formed in the cover 20 and the holding sheet 40 according to the lens position of the camera built in the portable display device 2. Since both the cover 20 and the holding sheet 40 are formed of a thin material, it is possible to easily drill a hole at a desired position.

  Further, the stereoscopic viewer 1 may be fixed to the user's head by attaching a belt to the stereoscopic viewer 1. Alternatively, an attachment device for attaching an external sensor or the like may be provided in the stereoscopic viewer 1.
