Description

  The present invention relates to a folding hat for protecting a human head.

  Protective caps such as helmets are used not only for the purpose of protecting the head from flying objects and falling objects, but also for the purpose of protecting the heads of passengers in transportation. In recent years, helmets for protecting the heads of bicycle riders have been regarded as important, and there are countries and schools that require bicycle riders to wear helmets. On the other hand, the helmet has a large volume and is inconvenient to carry when not worn. Therefore, conventionally, it is a riding helmet composed of a cap portion and an exchangeable outer cap body that covers the cap portion, and the cap portion is formed into a cap shape by folding a substantially spherical body formed by connecting a plurality of sheet materials. In addition, there is known a structure configured as a continuous air sac by fixing a folded sheet material on the front and back sides at a number of locations (for example, see Patent Document 1). In addition, the top, right side, left side, and back of the head are composed of separate plate-like members, and when worn, the right side, left side, and back of the head that overlap the top of the head are all slid and deployed to form the helmet shape. When not worn, a helmet is known that has a compact shape by sliding the right side, left side, and back of the head toward the top of the head (for example, see Non-Patent Document 1).

  An embodiment of the present invention will be described below with reference to the drawings.

  First, the configuration will be described. A foldable hat 1 according to this embodiment shown in FIG. 1 is a helmet for a bicycle occupant, and is used to protect the occupant's head from an impact at the time of a fall or a collision. It is done. The foldable hat 1 includes an outer frame portion 2 and an upper protection portion 3. The outer frame portion 2 and the upper protection portion 3 are formed of a hard resin having high impact resistance on the outside, for example, a PET resin, a PVC resin, and the like, and a resin having a high shock absorption on the inside, for example, foamed polystyrene, foamed polypropylene, polyurethane, etc. It is formed with. The outer sides of the outer frame portion 2 and the upper protection portion 3 may be formed of PC (polycarbonate) resin, ABS resin, FRP resin, or the like. The outer frame portion 2 and the upper protection portion 3 are formed to be slightly bent by a force applied from the outside.

  The outer frame portion 2 is formed in an annular shape and protects the side portion of the human head. That is, in a state where the foldable hat 1 is put on the human head, the head is covered from the forehead portion of the human head to the back of the head through the temporal region.

  The upper protection part 3 is provided across the front side which is one end of the outer frame part 2 and the rear side which is the other end, and protects the upper part of the human head. That is, in a state where the foldable hat 1 is put on the head of the human body, the head is covered from the forehead to the back of the head through the top of the head.

  As shown in FIGS. 1 and 3, the upper protection unit 3 includes a front protection unit 4 and a rear protection unit 5. The front protective part 4 is pivotally fixed to the front side of the outer frame part 2 by the first connecting part 6 so that the base end part is pivotally supported, and the forehead part of the human head is covered with the folding hat 1 on the human head. Cover from top to bottom. The rear protection part 5 is pivotally fixed to the rear side of the outer frame part 2 by the second connecting part 7 so that the rear end part can be pivoted. Cover from the back of the head to the top of the head.

  As shown in FIGS. 4 and 5, a locking portion 8 is provided at the front end portion of the front protection portion 4 and the front end portion of the rear protection portion 5. Specifically, a step-like first locking portion 9 is provided at the front end portion of the front side protection portion 4, and a reverse step-like second locking portion 10 is provided at the front end portion of the rear side protection portion 5. The first locking part 9 and the second locking part 10 are detachably provided. As long as the latching | locking part 8 is the structure which can latch the front side protection part 4 and the rear side protection part 5, what kind of thing may be sufficient as it. Further, in addition to the configuration shown in FIGS. 4 and 5, the locking portion 8 has an upper side from the inside of the upper protection portion 3 in a state where the first locking portion 9 and the second locking portion 10 are locked. It is desirable to have a lock mechanism (not shown) for preventing the locked state between the first locking portion 9 and the second locking portion 10 when a force is applied in the direction.

  As shown in FIG. 2 and FIG. 5, the front side protection part 4 and the rear side protection part 5 are formed on the outer frame part 2 in a state where the first locking part 9 and the second locking part 10 are separated. It is configured to be housed inside. That is, when the first locking portion 9 and the second locking portion 10 are separated, the front protection portion 4 and the rear protection portion 5 are arranged so that the front protection portion 4 is located above the rear protection portion 5. It is accommodated inside the outer frame portion 2 in an overlapped state.

  In order to make the front protection part 4 and the rear protection part 5 accommodated inside the outer frame part 2 with the first locking part 9 and the second locking part 10 detached. For example, the front side protection part 4 and the rear side protection part 5 are configured so as to descend in the center direction of the outer frame part 2 by their own weight, or the outer frames of the front side protection part 4 and the rear side protection part 5 It is conceivable that the position relative to the portion 2 is configured to be stable in the state shown in FIG.

  As will be described later, in the foldable cap 1 of this embodiment, the upper protection portion 3 is moved upward from the outer frame portion 2 by disengaging the first locking portion 9 and the second locking portion 10. And a folded state in which the upper protection part 3 is accommodated inside the outer frame part 2 can be formed.

  As shown in FIGS. 1 and 3, an opening 11 is formed between the outer frame portion 2 and the upper protection portion 3 in the hat state. The opening 11 is shaped and sized so that the human head exposed from the opening 11 does not contact the ground when the opening 11 contacts the substantially horizontal ground surface with the foldable cap 1 on the human head. Formed. In this embodiment, the thickness of the outer frame portion 2 and the upper protective portion 3 (the height direction size of the outer frame portion 2 and the upper protective portion 3 in FIGS. 4 and 5) is formed thick, while the opening Since the planar view size of the portion 11 (substantially vertical size and substantially horizontal size of the opening portion 11 in FIG. 1) is formed small, the opening portion 11 can be opened even if it contacts the substantially horizontal ground. The human head exposed from the portion 11 does not contact the ground. In addition, the opening part 11 plays the role of a ventilation hole, and suppresses the temperature rise of the human head wearing the foldable hat 1.

  Next, the operation of the foldable hat 1 of this embodiment will be described.

  First, when the folding hat 1 is changed from the folded state shown in FIGS. 2 and 5 to the hat state shown in FIGS. 1 and 4, the front protection part 4 and the rear protection part 5 are moved from the inside of the outer frame part 2. Pulling upward, bending the front protection part 4 and the rear protection part 5 while bringing the end face of the first locking part 9 and the end face of the second locking part 10 into contact with each other, the locking part 8 Lock. Thereby, as shown in FIG.1 and FIG.3, the front side protection part 4 and the rear side protection part 5 are connected, the upper side protection part 3 is formed in cross sectional view substantially arch shape, and the folding-type cap 1 will be in a hat state.

  Here, in the cap state, on the contact surface of the first locking part 9 and the second locking part 10, the front protection part 4 is on the rear side (in the direction of arrow P in FIG. 4), and the rear protection part 5 is Press each other forward (in the direction of arrow Q in FIG. 4). Therefore, the foldable hat 1 is maintained in the hat state.

  And in the state which covered the human body head with the foldable hat 1 in the state of a hat, the outer frame part 2 exerts a drag against the impact applied from the side of the human head and absorbs this shock, Protect. On the other hand, the upper protection unit 3 protects the human head by acting against the impact applied from the upper side of the human head and absorbing the shock.

  At this time, when the upper protection part 3 is subjected to an external impact on one of the front protection part 4 and the rear protection part 5, the other of the front protection part 4 and the rear protection part 5 is stretched. Function. For example, when an impact is applied to the front protection part 4 from the outside, this impact is caused by the pressing force with which the front protection part 4 presses the rear protection part 5 backward (in the direction of arrow P in FIG. 4) at the locking part 8. Acts. However, the rear side protection part 5 exerts a drag force that presses the front side protection part 4 in the opposite direction (the direction of the arrow Q in FIG. 4) against this pressing force. Similarly, when an impact is applied to the rear side protection part 5 from the outside, the rear side protection part 5 has a pressing force that presses the front side protection part 4 forward (in the direction of arrow Q in FIG. 4) at the locking part 8. Works. However, the front side protection part 4 exerts a drag force that presses the rear side protection part 5 in the opposite direction (the direction of the arrow P in FIG. 4) against this pressing force. Moreover, even when these pressing forces and drags are applied, the locked state of the locking portion 8 is maintained. Therefore, even when an impact is applied to the upper protection unit 3 from the outside, the hat state of the foldable hat 1 is maintained, and the human head is protected from the impact applied from the upper side.

  On the other hand, when the foldable hat 1 is changed from the hat state shown in FIGS. 1 and 4 to the folded state shown in FIGS. 2 and 5, the first protective member 4 is bent while the front protective part 4 and the rear protective part 5 are bent. The end surface of the stop portion 9 and the end surface of the second locking portion 10 are separated from each other, and the locking portion 8 is released. Thereby, the front side protection part 4 and the rear side protection part 5 descend | fall to the center direction of the outer frame part 2, and are accommodated in the inside of the outer frame part 2, and the foldable hat 1 is a compact folding state rather than a hat state. Become. By setting the foldable hat 1 to the folded state, the foldable hat 1 can be easily carried.

  As described above, in this embodiment, the foldable cap 1 can be configured with a simple structure by including the annular outer frame portion 2 and the upper protection portion 3, which are mainly configured. In addition, the cap state and the folded state are formed by causing the upper protection portion 3 to bulge or be accommodated with respect to the outer frame portion 2, thereby forming and folding the hat state with a simple operation. be able to. Thereby, it is possible to provide a foldable hat 1 that has a simple structure, can be manufactured at a low manufacturing cost, and is simple and easy to use at the time of forming and folding the hat state.

  In the above embodiment, when the first locking portion 9 and the second locking portion 10 are detached, the front protection portion 4 and the rear protection portion 5 are the same as those of the rear protection portion 5. It was set as the structure accommodated in the outer frame part 2 in the state which the front side protection part 4 overlapped on the upper side. However, instead of this, as shown in the modified example of FIG. 6, the front protection part 4 and the rear protection part 5 have the outer frame part 2 in a state where the rear protection part 5 overlaps the upper side of the front protection part 4. The structure accommodated in the inside may be sufficient.

  Further, although the folding hat 1 in the above embodiment is a bicycle occupant helmet, it is not limited to this, and even if it is a working or evacuation helmet for protecting the head from flying or falling objects Alternatively, it may be a helmet for passengers of a transportation vehicle such as an automobile or a motorcycle.

  The above embodiment is an exemplification of the present invention, and it is needless to say that the present invention is not limited to the above embodiment.
