The mounting tool 1 is an apparatus that can function as a head mounted display (HMD) 38 by being used in combination with an image display device 34 such as a smart phone 36.

  FIGS. 1 and 2 are views showing a state when the mounting tool 1 is expanded (expanded), and FIG. 3 is a view showing a state when the mounting tool 1 is contracted. As shown in FIGS. 1 to 3, the mounting tool 1 has a body 2, a fixing portion 24, a belt portion 26, and a lens holding portion 30.

  The body portion 2 has a front surface 4, a rear surface 6, an upper surface 8, a lower surface 10, and a side surface 12, and a surface disposed on the far side as viewed from the user 46 wearing the mounting tool 1 The front side is defined as a rear side 6, the upper side is defined as an upper side 8, the lower side is defined as a lower side 10, and the sides arranged on both sides are defined as a side 12.

  The body portion 2 is contracted in the lateral direction (deployment / contraction direction) 42 connecting the both side surfaces 12 by the expansion and contraction structure 40 provided on the rear surface 6, the upper surface 8 and the lower surface 10 to shorten the length or Expand in the direction 42 and lengthens. The expansion and contraction structure 40 is a so-called bellows-like structure, and is a structure configured by repeating a mountain fold and a valley fold.

  FIG. 4 is a development view of the body portion 2, but as shown in FIG. 4, the deployment / contraction structure 40 arranges the same shape triangles 20 so that their orientations are alternated, and the boundaries between the triangles 20 It becomes a fold and it is good also as a form constituted by repeating mountain fold and valley fold about the fold concerned. The configuration of the deployment / contraction structure 40 is not limited as long as it exhibits a function of contracting / expanding in the lateral direction 42 as described above.

  The rear surface 6 of the body portion 2 has two holes 18 for installing the lens 32, and the two holes 18 are arranged at a distribution position from half of the longitudinal direction (lateral direction 42) of the rear surface 6 Be done. The lens 32 is for correcting distortion of the image displayed on the image display device 34 so that the user 46 can view it. The specifications such as the outer diameter and the focal length are the size of the body 2. , And select an appropriate one according to the degree of distortion of the image.

  The front surface 4 of the body portion 2 has an opening 14 for allowing the user 46 to visually recognize the image displayed on the image display device 34 mounted on the front surface 4 from behind via the lens 32. 14 is substantially the same size as the front surface 4.

  The image display device 34 is fitted to the opening 14 of the front surface 4. However, when the image display device 34 is attached, the interior 16 of the body portion 2 is a space whose six sides are closed. Therefore, when the user 46 brings his eyes close to the lens 32 and looks at the image displayed on the image display device 34 through the lens 32, the light 16 from the outside hardly enters the inside 16 of the body 2 and the user The 46 can see the image more clearly.

There is a thing. The partition member serves to assign one inner space of the body 2 to one lens 32 so that the image for the right eye can be viewed only by the right eye of the user 46 and the image for the left eye can be viewed by the user 46 It becomes visible only with the left eye of

  6 to 9 are developed views of parts constituting the lens holding unit 30, and as shown in FIGS. 6 to 9, the lens holding unit 30 is a member for holding the lens 32 in the body portion 2. is there. When the lens holding unit 30 causes the lens 32 to contract, the front and back surfaces become perpendicular to the lateral direction 42 (the thickness direction of the lens 32 becomes substantially the same as the lateral direction 42), and When the body 2 is deployed, it is housed in the body 2 so that the lens 32 can move to the position of the hole 18. Generally, the thickness of the lens 32 is smaller than its outer diameter, so the mounting tool 1 may be made thinner in the expansion / contraction direction 42 at the time of contraction without being constrained by the outer diameter of the lens 32. it can.

  As shown in FIG. 3, since the mounting tool 1 has the body portion 2 having the above-described features, the thickness in the expansion / contraction direction 42 can be reduced at the time of contraction, so that the compactness when not in use Storage is not bulky and difficult to get in the way.

  10 and 11 are developed views of the side surface 12, the fixing portion 24, and the belt portion 26 of the body portion 2. FIG. As shown in FIGS. 1, 2, 10 and 11, the fixing portion 24 is a portion disposed on both side surfaces 12 of the body portion 2 and an end portion of the front surface 4, and the image display device 34 is attached. It is for fixing to 1 (at the position of the front surface 4 of the body 2). The fixing unit 24 includes a mechanism for fixing the image display device 34 such as a double-sided tape or a surface fastener at a portion in contact with the image display device 34.
