  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, in each figure referred below, an equivalent part is shown with the same code | symbol.

(Storage unit structure)
The structure of the storage unit according to this embodiment will be described with reference to FIG. Fig.1 (a) is a top view of the storage unit which concerns on this embodiment, FIG.1 (b) is the front view seen from the arrow Y1 direction.

  A storage unit 10 shown in FIG. 1 includes a main body 1 having an opening 11 and an open / close panel 2 of the main body 1.

  The main body 1 has a rectangular parallelepiped shape, and has a rectangular opening 11 on one surface thereof. Moreover, the main body 1 has a space for housing an electronic device such as a head amplifier. The open / close panel 2 has substantially the same shape as the opening 11 of the main body 1 and is a panel for making the opening 11 open or closed.

  The storage unit 10 is located on the first and second rotating shafts facing each other, and includes a first hinge part 30R and a second hinge part 30L for connecting the main body 1 and the open / close panel 2. Have Here, the rotation axis is a rotation center axis when the open / close panel 2 is opened and closed. For example, when the open / close panel 2 is opened from the closed state to the position R in FIG. 1A, the central axis of rotation of the adjustment screw 32a becomes the rotation axis. In the present embodiment, the first hinge portion 30R and the second hinge portion 30L have the rotation axes parallel to each other, that is, the first and second rotation axes are parallel to each other. However, the first and second rotation axes do not have to be parallel. For example, it may be a C shape.

  Furthermore, in the present embodiment, the first and second rotating shafts are parallel to each other and perpendicular to the upper surface of the main body 1, but may not be perpendicular to the upper surface of the main body 1. Even if the first and second pivot axes are not perpendicular to the upper surface of the main body 1 (that is, the pivot axes of the first hinge portion 30R and the second hinge portion 30L are relative to the upper surface of the main body 1). This is because the opening / closing panel 2 can rotate around any of the rotation axes.

  Further, the main body 1 is provided with female bases 3R and 3L that respectively constitute part of the first hinge portion 30R and the second hinge portion 30L on the left and right sides of the opening 11. Further, on the left and right sides of the opening / closing panel 2, male bases 4R and 4L are provided which constitute part of the first and second hinge portions 30R and 30L and engage with the female bases 3R and 3L of the main body 1.

  The male bases 4R and 4L are provided with knob screws 5R and 5L, respectively, for the operator to pinch with fingers when opening and closing the open / close panel 2. Further, the opening and closing panel 2 is fixed to the main body 1 by rotating the knob screws 5R and 5L and tightening them in the direction of the arrow Y1 (the direction perpendicular to the opening and closing panel 2).

(Hinge configuration)
FIG. 2 is a diagram illustrating a configuration example of the first hinge unit 30R. Since the first hinge portion 30R and the second hinge portion 30L are structurally symmetrical, the configuration of the first hinge portion 30R provided on the right side of the storage unit 10 will be described here. The description of the hinge part 30L is omitted. 2A is a plan view of the first hinge portion 30R, and FIG. 2B is a front view of the first hinge portion 30R viewed from the direction of the arrow Y2a.

  2C to 2E are views for explaining the configuration of the male base 4R. FIG. 2C is a plan view of the male base 4R. FIG. 2D is a male base 4R viewed from the direction of the arrow Y2b. FIG. 2E is a front view of the male base 4R viewed from the direction of the arrow Y2a.

  2 (f) to 2 (h) are diagrams for explaining the structure of the female base 3R, FIG. 2 (f) is a plan view of the female base 3R, and FIG. 2 (g) is a female base 3R viewed from the direction of the arrow Y2b. FIG. 2H is a front view of the female base 3R viewed from the direction of the arrow Y2a.

  FIG. 3 is a perspective view of the female base 3R and the male base 4R.

(Female base)
2 (f) to 2 (h), the female base 3R has two plungers 31a and 31b. Each of the plungers 31a and 31b is provided with spherical bodies 33a and 33b at one end, and provided with adjusting screws 32a and 32b at the other end. Compression springs 35a and 35b are provided between the sphere 33a and the adjustment screw 32a, and between the sphere 33b and the adjustment screw 32b, respectively.

  One end of the compression spring 35a is in contact with the sphere 33a, and the other end is in contact with the adjusting screw 32a. Similarly, one end of the compression spring 35b is in contact with the sphere 33b and the other end is in contact with the adjustment screw 32b. For this reason, when the adjustment screw 32a is rotated clockwise, the distance from the sphere 33a is shortened, and the pressing force of the compression spring 35a urging in the direction from the adjustment screw 32a to the sphere 33a is increased. Conversely, when the adjustment screw 32a is rotated counterclockwise, the distance from the sphere 33a is increased, and the pressing force applied by the compression spring 35a in the direction from the adjustment screw 32a to the sphere 33a is reduced.

  The same applies when the adjustment screw 32b is rotated clockwise or counterclockwise. That is, the spheres 33a and 33b are biased in the axial direction of the rotation shaft. The plungers 31a and 31b are arranged so that the respective spheres 33a and 33b face each other.

(Male base)
Referring to FIGS. 2C to 2E, the male base 4R is provided with a knob screw 5R and recesses 41a and 41b. In the closed state of the open / close panel 2, the recesses 41a and 41b are configured to engage with parts of the spheres 33a and 33b of the plungers 31a and 31b, respectively. That is, the spherical body 33a and the concave portion 41a of the plunger 31a and the spherical body 33b and the concave portion 41b of the plunger 31b constitute an engaging portion, respectively.

  As described above, in any one of the first hinge portion 30R and the second hinge portion 30L, the engagement state of the pair of engagement portions including the sphere 33a and the recess 41a and the sphere 33b and the recess 41b is released. As a result, the opening / closing panel 2 can be rotated about the other corresponding rotation axis. Here, “the other corresponding rotation shaft” means a rotation different from the rotation shaft where the first or second hinge portion 30R, 30L having the engagement portion whose engagement state is released is located. Refers to the moving axis. For example, the engagement state of the pair of engaging portions including the sphere 33a and the recess 41a of the first hinge portion 30R and the sphere 33b and the recess 41b is released, and the open / close panel 2 rotates to the left in FIG. In this case, the rotation axis of the second hinge portion 30L becomes the “other corresponding rotation axis”.

(Open / close panel open / close operation)
In FIG. 1, for example, when the opening / closing panel 2 is opened to the left with the second hinge 30L on the left side of the opening / closing panel 2 as an axis, the left and right knob screws 5R, 5L are loosened and the knob screw 5R is pinched with a finger or the like. Then pull it forward. Then, the plungers 31a and 31b, which are elastic bodies, are contracted, and the spheres 33a and 33b are disengaged from the recesses 41a and 41b, so that the distance between the sphere 33a and the sphere 33b is increased. When the knob screw 5R is further pulled, the engaged state between the male base 4R and the female base 3R is completely released. In the above case, the central axis of rotation of the adjustment screw 32c of the hinge portion 30L is the rotation axis.

  Further, when opening the open / close panel 2 to the right, the same operation as described above is performed. That is, when the knob screw 5L is pulled strongly with a finger or the like, the plunger constituting the second hinge portion 30L is contracted, so that the engaged state between the male base and the female base constituting the second hinge portion 30L is released. In this case, the central axis of rotation of the adjustment screw 32a of the hinge part 30R becomes the rotation axis.

  If it is desired to fix the opening direction to either the left or right, the first hinge portion 30R or the second hinge is tightened by tightening the right adjustment screw 32a and 32b or the left adjustment screw 32c to the limit. The part 30L can be used as a fixed hinge.

  Further, for example, when closing the open / close panel 2 to the right with the second hinge portion 30L on the left side of the open / close panel 2 as an axis, the knob base 5R is pinched and the male base 4R is pressed against the female base 3R. Then, the spheres 33a and 33b of the plungers 31a and 31b are pushed in the direction of the adjusting screws 32a and 32b by the male base 4R, whereby the plungers 31a and 31b, which are elastic bodies, are contracted, and the space between the sphere 33a and the sphere 33b is widened. When the male base 4R is further pushed into the female base 3R, the spheres 33a and 33b enter the recesses 41a and 41b, respectively, and at the same time, the plungers 31a and 31b are extended by the restoring force, so that the sphere 33a and the recess 41a , Respectively.

  At this time, the tip of the knob screw 5R is fitted in the hole 34R provided in the female base 3R. Further, if the knob screw 5R is strongly tightened with the tip of the knob screw 5R fitted in the hole 34R, the open / close panel 2 is fixed to the main body 1. Moreover, what is necessary is just to operate the female base 3L similarly with respect to the male base 4L, when closing an opening-and-closing panel to the left.

(Adjustment with adjustment screw)
The open / close panel 2 hangs down in the vertical direction due to its own weight, but the position of the open / close panel 2 in the direction perpendicular to the horizontal plane can be obtained by tightening or loosening the adjusting screws 32a, 32b of the plungers 31a, 31b. Can be adjusted. For example, since the vertical position of the open / close panel 2 can be adjusted so that the tips of the knob screws 5R and 5L are aligned with the centers of the holes 34R of the female bases 3R and 3L, the knob screws 5R and 5L can be smoothly tightened. Can do.

  Moreover, since the knob screws 5R and 5L have a drop-off preventing structure, even if they are loosened, they are not dropped from the male bases 4R and 4L.

  Further, the hardness and upper / lower balance of the engagement of the male base 4R and the female base 3R, and the engagement of the male base 4L and the female base 3L (that is, the engagement between the spheres 33a and 33b and the recesses 41a and 41b, etc.) It is possible to adjust by.
