  An embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows the entire helmet 1 of the present invention. The helmet 1 is composed of a base 2 and a cap body 51. A single hat-shaped helmet is divided in a substantially horizontal direction, and a base 2 is provided below and a cap body 51 is provided above. For this reason, the base 2 is formed in a headband shape and an annular shape, and has a space serving as a storage position 3 on the inner wall side. The base 2 in the present embodiment is further divided into a base body 11 and an intermediate base 31.

  Although not shown in the drawing, when the helmet 1 is used, a cushioning material made of foamable resin or the like is disposed inside the cap body 51, and a wearing belt is disposed on the inner wall of the base 2.

  In this description, the direction having the flange 12 will be described as the front direction, the opposite side as the rear direction, the state in which the helmet 1 can be used is in the use state (see FIG. 1), and the state in which the cap body 51 is inverted and stored is stored. The state (see FIG. 5) will be described. Moreover, the side which the user of the helmet 1 wears is demonstrated inside, and the other side is demonstrated as an outer side.

  The basic functions in this embodiment will be described. The lock | rock part 16 arrange | positioned in the front inner side of the base 2 is cancelled | released from the helmet 1 of the use condition shown in FIG. Then, as shown in FIG. 2, the cap body 51 is rotated and started up, and when the cap body 51 is started up to the position shown in FIG. 3, the engagement between the intermediate base 31 and the base body 11 is released. In the state where the cap body 51 is raised, the cap body 51 is rotated so as to be reversed upside down as shown in FIG. 4, and the cap body 51 is further rotated in the direction opposite to the rising direction, as shown in FIG. As shown, the cap body 51 can be stored in the storage position 3 inside the base. In actuality, the intermediate base 31 is disengaged in the state shown in FIG. 3, and the intermediate base 31 falls inward of the base body 11. In FIG. 11 shows a state where it is not housed.

  As described above, the reverse storage helmet 1 of the present invention is characterized by combining the rotation for opening the cap body 51 upward and the rotation for reversing the cap body 51 upside down into the storage state. And

The structure of the helmet according to this embodiment will be described with reference to FIGS.
The base body 11 is a ring-shaped or headband-like plate-like member that corresponds to the lower part of the entire helmet 1 when in use. The front of the base body 11 having the collar 12 is located near the user's forehead when worn, and the rear of the base body 11 is located near the user's back head. The height of the base body 11 is about one third of the total height that is the height to the top of the cap body 51 in the front of the helmet 1 and about one half in the rear.

  The intermediate base 31 has a substantially C-shaped form in which a part of the annular body is cut out in a plan view, and a substantially fan-shaped form having a radially expanding shape from the front ends 32 and 32 to the rear in a side view. In the side view, in the vicinity of the ends 32, 32 of the intermediate base 31, the intermediate base 31 is pivotally supported by pivot support shafts 33, 33 at pivot support positions 13, 13 that are slightly in front of the center of the side surface of the base body 11. By this shaft support, the intermediate base 31 rotates in the vertical direction (in the direction of arrow line Z in FIG. 6) with the rotation support shafts 33 and 33 as fulcrums.

  A central portion on the rear side of the intermediate base 31 is recessed, and a recess 34 for arranging the engagement panel 71 is formed. By disposing the engagement panel 71 in the recess 34, the outer surface of the intermediate base 31 and the outer surface of the engagement panel 71 are formed on the same plane in the use state. It is integrated with the base 31 and the base 2. Thereby, as will be described later, the first rotation shafts 74 and 74 disposed on the engagement panel 71 are disposed on the upper end which is one end portion of the intermediate base 31 and the base 2.

  The intermediate base 31 in the storage state is stored along the inner side of the inner wall of the base body 11 from the pivot support positions 13 and 13 of the base body 11 to the rear (see FIG. 5). From this state, when the intermediate base 31 is raised, it is disposed so as to rise further from the inner side of the upper end edge of the base body 11 in a side view.

  A panel engagement convex portion 72 that protrudes outward is formed at a height position corresponding to the lower end of the intermediate base 31 that is the lower end of the engagement panel 71. On the other hand, a panel engaging recess 14 is formed at the upper edge of the base body 11 so as to be recessed inward at the upper edge. When the intermediate base 31 rotates and rises, the panel engagement convex portion 72 engages with the panel engagement concave portion 14, and the intermediate base 31 holds the state of rotating and rising. This engaged state is held by an elastic body 75 that urges the engaging panel 71 outward. In the present embodiment, the elastic body 75 uses a resin spring, but other things such as a coil spring may be used.

  Next, the cap body 51 will be described with reference to FIGS. The cap body 51 is disposed above the base body 11 and the intermediate base 31 in the use state. The cap body 51 covers the user's forehead and top, and has a substantially semicircular shape when viewed from the side. The substantially semicircular shape is a dish-like shape in which a sphere is cut out by about one-third to one-fourth. In the side view, the lower edge 52 of the cap body 51 is inclined to the right shoulder. The cap body 51 is curved as a whole, and has a rear bent portion 54 that bends from the rear thereof, and this curved portion is located between the user's top and back.

  As will be described later, it has a front hanging piece 53 that hangs downward from the front side end of the cap body 51, and engages with the front recessed portion 15 that is recessed inside the front upper end of the base body 11. A second turning shaft support portion 59 is disposed inside the rear bent portion 54 of the cap body 51, and the second turning shaft support portion 59 supports the first turning shafts 74 and 74. A second rotating shaft 82 protruding from the moving base 81 is supported to be rotatable.

  Side drooping pieces 55, 55 projecting further downward are formed from the lower edges 52 on both sides of the cap body 51. The side hanging pieces 55 and 55 are engaged with the side recesses 35 and 35 inside the upper end edges on the side of the base body 11 and the intermediate base 31 so as to prevent the cap body 51 in a used state from rattling.

  In addition, the lower edge 52 of the cap body 51 is formed so that the entire upper end edge of the base body 11 or a part thereof is supported from below, and support pieces 17 and 17 are formed at least from the upper edge of the base body 11. The lower edge 52 is supported from below.

  A to-be-locked piece 56 having an opening 57 is formed by hanging downward from the front hanging piece 53 of the cap body 51, and a lock portion 16 that is urged in the locking direction is disposed on the front inner side of the base body 11. The state where the cap body 51 is disposed on the base body 11 can be maintained by engaging the key portion of the lock portion 16 with the opening 57. When the cap body 51 is stored after releasing this state, the user manually presses the lower portion of the lock portion 16 to release the engaged state with the locked piece 56, thereby removing the cap body 51. It can be turned in the direction of rising.

  Next, a mechanism in which the cap body 51 is rotated by the first rotation shafts 74 and 74 and the second rotation shaft 82 will be described.

  As shown in FIG. 8, the engagement panel 71 disposed in the recess 34 behind the intermediate base 31 is formed with shaft holding portions 73, 73 protruding further upward from both sides of the upper end thereof. Horizontal first rotation shafts 74 and 74 projecting inward from 73 and 73 are arranged. The first rotation shafts 74 and 74 have a rotation base 81 connected to the cap body 51 rotatably supporting the first rotation shafts 74 and 74, and the cap body 51 is vertically moved with the shaft as a fulcrum. (See FIGS. 2 and 3).

  The first rotation shafts 74 and 74 protrude from the shaft holding portions 73 and 73 by a predetermined length, but may be a single shaft. Moreover, since it is located in the back of the helmet 1 in a present Example, it is a horizontal axis which makes the direction which goes from one side surface side to the other side surface a longitudinal direction, However, The direction of a longitudinal direction is limited to this It is not a thing.

  The rotation base 81 and the second rotation shaft 82 will be described. As shown in FIG. 9, the rotation base 81 in the present embodiment is formed such that a cylindrical second rotation shaft 82 protrudes from the tip side, and the first rotation shafts 74 and 74 are rotated on the end side. It has a bearing portion 83 that is freely supported. The rear bent portion 54 of the cap body 51 has a rotation hole through which the second rotation shaft 82 passes, and a second rotation having a shaft convex portion 60 that engages with the shaft recess 84 of the second rotation shaft 82. By attaching the shaft support portion 59, the cap body 51 is supported so that it can be rotated and reversed with the second rotation shaft 82 as a fulcrum.

  The second rotating shaft 82 has a longitudinal direction that intersects the first rotating shafts 74 and 74 in the horizontal direction. The intersecting direction is a direction intersecting the longitudinal direction of the first rotation shafts 74 and 74 in a plan view. The reverse storage type helmet 1 of the present invention is characterized by combining rotation in a direction to open the cap body 51 and rotation in a direction in which the cap body 51 is reversed upside down. What is necessary is just to perform the mutually independent independent rotation by an axis | shaft and to cross | intersect in planar view.

  The cap body 51 that is turned up by the first turning shafts 74 and 74 is inverted so as to be turned upside down by the second turning shaft 82 (see FIG. 4). From the state in which the cap body 51 is inverted, the cap body 51 is stored in the storage position 3 of the base body 11 by further rotating the first rotary shafts 74 and 74 in the direction opposite to the rising direction. (See FIG. 5).

  A structure for releasing the engagement between the intermediate base 31 and the base body 11 will be described. As shown in FIG. 10, the engagement panel 71 mounted on the intermediate base 31 is between the upper-end shaft holding portions 73, 73 and the lower-end panel engagement convex portion 72, and has shaft holes on both sides thereof. A shaft (not shown) disposed on the side surface of the recess 34 of the intermediate base 31 is rotated about the shaft as a fulcrum.

  The engagement panel 71 has an engagement release portion 77 that protrudes upward on the outer side of the upper edge between the shaft holding portions 73 and 73. The rotation base 81 and the cap body 51 are turned up with the first rotation shafts 74 and 74 as fulcrums, and in a state of reaching the substantially vertical direction, the cylindrical outer portion of the bearing portion 83 of the rotation base 81 is provided. The surface contacts the disengagement part 77. This is because the thickness of the bearing portion 83 in the side view is different from the distance (Y) in one direction from the center line and the distance (Y) in the other direction. When the rotation base 81 and the cap body 51 are further rotated from this state, a force for pushing the engagement release portion 77 of the engagement panel 71 to the outside acts, and the engagement panel 71 is rotated and the lower end panel engagement. The engagement between the mating convex portion 72 and the panel engaging concave portion 14 of the base main body 11 can be released.

  The helmet 1 in the present embodiment accommodates the cap body 51 in the accommodation position 3 by two different rotations, the rotation by the first rotation shafts 74 and 74 and the rotation by the second rotation shaft 82. Can do. Further, by concentrating all of these shafts and the engagement panel 71 behind the helmet 1, a shaft having a predetermined thickness and strength can be used.

  Further, by dividing the base 2 into the base main body 11 and the intermediate base 31, not only the cap body 51 can be stored, but also the height of the base 2 in the height direction can be reduced. Moreover, the first rotation of the cap body 51 and the disengagement of the intermediate base 31 are performed by a series of operations, and the helmet 1 can be stored by a simple operation.
