  Configurations other than those described above are the same as those in the first embodiment.

  Next, the operation of the foldable cap 50 of the second embodiment will be described.

  As shown in FIG. 11, the foldable cap 50 according to the second embodiment has the lever member main body 54 of the left and right lever members 52, 52 in a state where the front flat plate 12 and the rear flat plate 13 are in the flat plate state. , 54 are pushed downward from above. Then, the lever members 52, 52 are rotated downward about the pins 57, 57, and the tethers 23, 23 are directed toward the outside of the folding hat main body 50A in accordance with the operation of the lever members 52, 52. Be pulled. Here, when the user pushes down the lever members 52, 52, the pins 57, 57 serving as fulcrums at the time of rotation exist on the longitudinal base end side of the lever members 52, 52, and the longitudinal direction is substantially the same. There are connecting rods 58, 58 to which the tethers 23, 23 that are the action points are connected at the center, and there is a user's gripping portion that is a force point on the distal end side in the longitudinal direction. Therefore, according to the lever principle, even if the tension of the tethers 23 and 23 is strong, the user can rotate the lever members 52 and 52 and pull the tethers 23 and 23 with a small force.

  On the other hand, when the lever members 52 and 52 are pushed down, the lever members 52 and 52 press the left and right bent inclined portions 15b and 15c inward by the tension of the tethers 23 and 23, and the pressing force of the front flat plate 12 is increased. The first hinge portion 12bx and the second hinge portion 12by, and the third hinge portion 13bx and the fourth hinge portion 13by of the rear flat plate 13 are elastically deformed, respectively. As a result, the front flat plate 12 and the rear flat plate 13 are deformed against the elastic force, thereby forming a hat state that is a shape to be put on the head in a state where the folding hat main body portion 10A is unfolded.

  Then, by depressing the lever member 52, the inner position P2 of the virtual line L1 from the outer position P1 than the virtual line L1 connecting the lower end of the tether insertion hole 15d and the outer periphery of the pin 57 shown in FIG. In addition, when the axial center portion of the connecting rod 58 of the lever member moves, the tension F1 of the tether 23 on the connecting rod 58 generates a component force F2 in the vertical direction on the surface of the inclined edge 12cy (and the inclined edge 12cz). Since this component force F2 acts as a force for rotating the lever member 52 toward the inner position P2, the lever members 52 and 52 are pushed down so that the lever member main body portions 54 and 54 are in contact with the inclined edges 12cy and 12cz. Fixed. Thereby, the unfolded state of the folding hat main body 50A is maintained.

  Instead of grasping and pushing down the lever member main body 54, the user grasps the chin strap 24 and pulls it down to rotate the lever member 52 downward, thereby folding the foldable hat main body 50A. It is also possible to keep the unfolded state in a hat state.

  17 and 18, the cover member 70 is put on the surface of the foldable hat main body 50A, and the locking holes 71a, 71b, 71c, 71d are engaged with the locking members 62a, 62b, 62c, 62d. When locked, the cover member 70 is mounted on the surface of the foldable hat main body 50A. In this state, substantially the entire surface of the foldable hat main body 50 </ b> A is covered with the cover member 70. When the user wears the foldable hat main body 50A on the head, the foldable hat main body 50A can reliably protect the head from the impact of falling objects and the like, and the cover member 70 can be used from heat and flame. Can protect the person's head. Furthermore, when the user wears the foldable hat main body 50A on the head, the rear covering member 74 of the cover member 70 is covered from the user's neck to the shoulder, so that the user's heat and flames can prevent the Can be protected from the neck to the shoulder.

  On the other hand, when the use of the unfolded folding hat 50 is finished and the folding hat body 50A is desired to be changed from the hat state to the flat state, the user removes the folding hat body 50A from the head and moves the lever. The lever member main body portions 54, 54 of the members 52, 52 are pulled upward. Then, the axial center portion of the connecting rod 58 of the lever member 52 moves from the inner position P2 to the outer position P1 with respect to the imaginary line L, and the shape of the folding hat main body 50A is shown in FIG. 12 from the state shown in FIG. When the state shifts to the state, the lever member 52 is pushed down and fixed by the component force F2, and the tension of the tethers 23 and 23 is loosened, and the lever members 52 and 52 are bent to the left and right bent inclined portions 15b and 15c. The pressing force that presses inward becomes weaker. As a result, the front flat plate 12 and the rear flat plate 13 are in a flat plate state, and the foldable hat main body 50A is in a flat plate state.

  When the cover member 70 is attached to the foldable hat main body 50A in the flat state, the rear covering member 74 is folded, and the mounting rivet is attached from the surface side of the cover member 70 as shown in FIG. A pair of bands 75a and 75b are attached to 62a, 62b, 62c, and 62d, and the rear covering member 74 is folded and bundled with the bands 75a and 75b. Thereby, it becomes possible to store and accommodate in a compact manner with the cover member 70 attached to the foldable hat main body 50A.

  As described above, according to the second embodiment, the unfolded state holding mechanism 51 of the foldable hat main body 50A has the lever member 52 provided on the outer side of the side portion so that the longitudinal base end portion is rotatable in the vertical direction. And has one end portion connected to the middle portion in the longitudinal direction of the lever member 52, and a tether 23 extending through the side portion to the inside, and rotating the lever member 52 downward. As a result, the anchoring body 23 is pulled to be held in the unfolded state, so that when the distal end side of the lever member 52 is gripped and pulled down, the lever member 52 becomes the pin 57 at the longitudinal base end. The anchoring body 23 can be pulled with a small force by the lever principle, and the unfolded state of the folding hat main body 50A can be maintained. Thereby, the unfolded state holding mechanism 51 can be reliably functioned with a simple operation and a small force.
