Japanese Utility Model Publication No. 7-43450

  However, the device described in Patent Document 1 has a curved crease that is curved at a position slightly apart from an opening of a size provided in the central portion of a single thin plate body, and the curved crease. It is structurally unsuitable for the provision of a foldable hat composed of an elastic flat plate whose shape is stable in a flat plate state because it is configured to be held in an unfolded state (wearable state) by folding In addition, since it is made of a single thin plate (1), it is liable to cause deformation or breakage due to contact or collision with other objects, and is not suitable for avoiding danger. On the other hand, if an attempt is made to increase the shock absorption and penetration resistance of the foldable hat against falling objects, the elastic flat plate will naturally become thick, and the functionality of compact storage may be impaired by folding.

  In view of the above circumstances, the present invention provides a foldable hat that facilitates compact storage by folding while ensuring sufficient shock absorption, penetration resistance, etc. against falling objects and the like to protect the human head. The purpose is to do.

  In order to achieve the above-mentioned object, the invention according to claim 1 is a hat state in which a pair of plate members are connected by a bent portion and are covered with a human head in the unfolded state. A foldable hat provided with a foldable hat main body that is folded by being bent through the foldable portion, the plate material on both sides of the foldable portion at the top of the foldable hat main body. A pair of folding-type cap reinforcing plate materials for protecting the top of the human head from falling objects is attached symmetrically with respect to the bent portion, and in the attached state, The plate surface of the foldable hat reinforcing plate is in a state substantially along the plate surface of the foldable hat main body at the attached position, and each of the foldable hat reinforcing plate has one end side of the foldable hat reinforcing plate. Hat body At the same time, the other end side of the folding head body is attached at a position lower than the position at which the one end side is attached. The one end portions of the folding-type hat reinforcing plate are attached to the folding-type cap body in a state of being opposed to each other with the folding portion of the folding-type hat body sandwiched therebetween.

  According to a second aspect of the present invention, in addition to the configuration of the first aspect, each of the folding-type cap reinforcing plate members is formed such that the one end side is wide in the direction along the bent portion, and the other The end side is formed narrower than the one end side.

  The invention according to claim 3 is, in addition to the structure according to claim 1 or 2, the plate material for reinforcing the cap is more flexible than the plate member side member disposed on the plate member side, and the plate member side member. And a cushioning member disposed on the head side.

  According to a fourth aspect of the present invention, in addition to the configuration according to the third aspect, the folding-type cap reinforcing plate is formed in a substantially triangular shape when viewed from the front, and each apex portion on the plate surface of the plate-side member. Locking means that is locked to the inner surface side of the plate material is disposed in the vicinity, and the locking device is locked to the inner surface side of the plate material by three-point support.

  According to a fifth aspect of the invention, in addition to the configuration of the fourth aspect, the locking means of the folding-type cap reinforcing plate is protruded in a substantially vertical direction with respect to the plate surface of the plate-side member. A gap is formed between the plate member side member and the plate member in a state of being attached to the plate member.

  The invention according to claim 6 is characterized in that, in addition to the structure according to claim 4 or 5, the locking means of the folding-type cap reinforcing plate is a hook-and-loop fastener.

  According to the first and second aspects of the present invention, the folding hat reinforcing plate is disposed at a position corresponding to the vicinity of the top of the folding hat when the folding hat is put on the human head. By doing so, it is possible to increase the shock absorption of the top of the folding hat. In other words, a folding reinforcement plate can be placed on the top of the head where shock absorption is particularly necessary to protect the human head from falling objects, etc., so that the shock absorption of the folding hat is ensured by this reinforcement plate. it can. For this reason, it is easy to form the plate so that the thickness and rigidity of the plate can be easily changed as compared with the case where the human head is protected only by the shock absorption and penetration resistance of the plate. As a result, the folding cap can be easily accommodated in a compact manner by folding while ensuring sufficient shock absorption, fall resistance and the like for falling objects and the like to protect the human head.

  According to the third aspect of the present invention, the plate member side member disposed on the plate member side and the buffer member disposed on the head side and having more flexibility than the plate member side member are configured to overlap each other. Therefore, the plate member side member ensures the penetration resistance of the reinforcing plate member and the shock absorbing member ensures the shock absorbing property, and the material and thickness of the plate member side member and the buffer member are adjusted separately. Thus, it is possible to freely adjust the penetration resistance and the shock absorption of the reinforcing plate at the manufacturing stage. Furthermore, since the flexible buffer member is provided on the head side, the head can be protected from an impact when a fallen object or the like collides. Thereby, the penetration resistance and the shock absorption suitable for the actual situation of the foldable hat can be ensured, and the safety of the foldable hat can be enhanced.

  According to the invention described in claim 4, by providing a locking means that is locked to the inner surface side of the plate material, the reinforcing plate material and the front elastic flat plate or the rear elastic flat plate are detachably formed, Replacement and maintenance of the reinforcing plate can be facilitated. The folding prevention reinforcing plate is formed in a substantially triangular shape when viewed from the front, and a locking means that is locked to the inner surface of the plate is provided in the vicinity of each apex portion of the plate of the plate side member. The locking state can be prevented from becoming unstable by being locked to the inner surface side of the plate member by three-point support by the locking means. When the folding hat has a bent portion in the vicinity of the top of the head, two locking means are attached in the vicinity of the bent portion, and the other one locking means is connected to the two locking means. Since the reinforcing plate is attached at a position away from the bent portion, the side with the larger area of the reinforcing plate is arranged on the top portion side, and the side with the smaller area is arranged on the portion where the amount of bending due to folding is large. Is possible. This protects the human head from falling objects, etc., especially by protecting the top of the head, which requires penetration resistance and shock absorption, with a large area reinforcing plate and locking it with high strength. In addition to ensuring the protection of the top of the head, even if the amount of bending when the plate is folded is different from the amount of bending when the reinforcing plate is folded, the difference prevents the folding from becoming difficult to prevent folding. Compact storage by folding the type hat can be realized reliably.

  According to the fifth aspect of the present invention, the latching means protrudes in a substantially vertical direction with respect to the plate surface of the plate member side member, and is attached to the plate member, and the folding hat reinforcing plate member and the plate member. Since a gap is formed between the two, the impact is absorbed by the expansion and contraction of the locking means in this gap, and the folding hat reinforcing plate at the time of elastic deformation of the plate The difference in the amount of bending with respect to the foldable hat is absorbed, so that it is possible to more reliably secure the shock absorption of the fallen object or the like in the foldable hat and to make compact storage by folding easier.

  According to the invention described in claim 6, since the locking means is a surface fastener, the effect of absorbing the difference in the amount of bending between the plate material and the reinforcing plate material is further enhanced while securing a high locking state. It can be obtained as an effect.

The entire surface of the flat plate side plate material 42a is formed to have substantially the same thickness. On the other hand, as shown in FIG. 11B, the thickness of the buffer member 42b is, as viewed from the side, the apex side between the two isosceles sides of a substantially isosceles triangle in the front view (the lower side in FIG. 11A). Side), and as shown in FIG. 11C, it is thicker at the center in plan view.

  As shown in FIG. 12, on the flat plate side plate 42 a side of the reinforcing plate 41, surface fastener male bodies 43 a, 43 b, 43 c as “locking means” are arranged in the vicinity of each apex portion of the substantially isosceles triangle. Has been. The surface fastener male bodies 43a, 43b, and 43c are provided so as to protrude in a substantially vertical direction with respect to the plate surface of the flat plate side plate member 42a.

  On the other hand, as shown in FIG. 6, surface fastener female bodies 44 a, 44 b, 44 c as “locking means” are arranged on the inner surface side of the front elastic plate 12 and the inner surface side of the rear elastic plate 13. Yes. The two hook-and-loop fastener female bodies 44a and 44b are located in the vicinity of the folding portion 15 and the top portion (this specification) covers the position corresponding to the top of the head when the foldable cap body 10 is put on the human head. The one hook-and-loop fastener female body 44c is placed farther from the horizontal portion 15a than the two hook-and-loop fastener female bodies 44a and 44b, i.e., the foldable cap body 10 is placed on the head. In the frontal position or the occipital position relative to the top of the head. The surface fastener female bodies 44 a, 44 b, 44 c are provided so as to project in a substantially vertical direction with respect to the plate surface of the front elastic flat plate 12 and the plate surface of the rear elastic flat plate 13.

  Then, as shown in FIG. 6, the three surface fastener female bodies 44 a, 44 b, 44 c correspond to the positions of the surface fastener male bodies 43 a, 43 b, 43 c on the reinforcing plate member 41, that is, the reinforcing plate member 41. It is disposed at a position corresponding to the apex position of the substantially isosceles triangle shape. As shown in FIGS. 6 and 8, the two reinforcing plate members 41 and 41 are formed by folding the hook-and-loop fastener male bodies 43a, 43b and 43c to the hook-and-loop fastener female bodies 44a, 44b and 44c. The main body 10 is attached to the front elastic flat plate 12 and the rear elastic flat plate 13. That is, the reinforcing plate member 41 and the front elastic flat plate 12 and the reinforcing plate member 41 and the rear elastic flat plate 13 are respectively the surface fastener male bodies 43a, 43b, 43c and the surface fastener female bodies 44a, 44b, 44c. By being locked, it is locked by three-point support.

  In this state, as shown in FIG. 6, the two reinforcing plate members 41 and 41 are each attached with the base side of the isosceles triangle along the bent portion 15, and the apex side of the isosceles triangle is attached to the frontal side and the occipital side. In this state, the two reinforcing plate members 41 and 41 are attached to the bent portion 15 at a substantially line symmetrical position.

  As shown in FIG. 8, the surface fastener male bodies 43 a, 43 b, 43 c projecting substantially perpendicularly to the plate surface of the flat plate side plate material 42 a, the plate surface of the front elastic plate 12, and the plate of the rear elastic plate 13. In a state where the hook-and-loop fastener female bodies 44a, 44b, and 44c protruding substantially perpendicular to the surface are locked, the reinforcing plate 41 and the front elastic plate 12 and the reinforcing plate 41 and the rear A gap 45 is formed between the opposing plate surfaces of the side elastic flat plate 13.

  Next, the operation of this embodiment will be described.

  In the folded state as shown in FIG. 10, the foldable hat main body 10 is configured to push the lower end portion of the left bending inclined portion 15b and the lower end portion of the right bending inclined portion 15c simultaneously in the direction approaching each other. The elastic flat plate 12 and the rear elastic flat plate 13 are curved and deployed. At this time, the outer surface portion of the distal end portion 21d of the elastic piece portion 21b slides with respect to the locked pin 23 shown in FIG. 7A, and as shown in FIG. 21e gets over the locked pin 23 and is locked. By this locking, the unfolded state is maintained and a hat state is formed.

  As a result, it is possible to make the deployed state very simple simply by applying an external force in a direction in which the portions facing the both sides of the bent portion 15 are approached. It can be applied instantly during a disaster, and the head can be protected from falling objects.

  Further, in this unfolded state, the elastic piece portion 21b protrudes outside from the opening 15d of the bent portion 15. However, since the elastic piece portion 21b is covered with the upper flange portion 15e, it can be prevented from being caught. .

  Further, by fixing the locking member 21 having a predetermined strength to the bent horizontal portion 15a of the bent portion 15, the strength against the falling object can be improved.

  Further, reinforcing plate members 41 and 41 are attached to the top portions of the front elastic plate 12 and the rear elastic plate 13 of the foldable cap body 10, respectively, so that they face the top of the person wearing the foldable cap. Reinforcing plate members 41 and 41 are provided at the positions where the tops are protected by the reinforcing plate members 41 and 41 as well as the front elastic plate 12 and the rear elastic plate 13.

  Furthermore, when folding from this unfolded state, the pressing portion 21f of the elastic piece portion 21b is pressed in the direction of the arrow in FIG. As a result, by removing the locking portion 21e from the locked pin 23, the elastic force of the front elastic flat plate 12 and the rear elastic flat plate 13 makes them flat, and the elastic piece portion 21b passes through the opening 15d. It will be retracted into the cap (see FIG. 7B).

  In such a case, since the locked state of the locked pin 23 and the locking portion 21e can be easily released, it can be folded very easily. In this folded state, the storage property is very good.

  On the other hand, since the interior member 30 is in a folded state and an unfolded state, each of the front band portion 33 or the rear band portion 34 having a predetermined rigidity is in a straight state or a curved state. Although the distance L between the connecting rivets 36 of 33 and 34 changes, the attachment portion 31c of the hammock 31 rotates around the attachment rivet 31d, so each band attached to the intermediate portion of the extension piece portion 31b. Even if the distance L of the connecting rivet 36 of the portions 33 and 34 changes, it can be followed by the rotation. The headband 32 can be unfolded and folded in both the unfolded state shown in FIG. 7A and the folded state shown in FIG. 7B.

  Even when the circumference of the headband 32 is adjusted by operating the dial portion 38, the length of the front band portion 33 is adjusted because the mounting portion 31c of the hammock 31 rotates about the mounting rivet 31d. be able to.

  In addition, since the front band portion 33 and the rear band portion 34 of the headband 32 have a predetermined rigidity, the hat can be firmly fixed when the headband 32 is attached to the head.

  Further, since the front band portion 33 and the rear band portion 34 having the predetermined rigidity are provided with a connecting portion 35 having flexibility provided at a position corresponding to the bent portion 15, the head band 32 is attached. Can be folded well.

  And since the front side band part 33 and the rear side band part 34 are exhibiting the shape of a long plate, even if it folds, a cap can be folded thinly, without being bulky.

  Furthermore, in order to adjust the circumferential length of the headband 32 according to the size of the head, the dial portion 38 can be operated and adjusted from the front side of the front band portion 33, so that the operability is extremely good. Incidentally, in a normal helmet, there is almost no gap between the front part of the headband and the helmet body (cap body), so it is impossible to secure a space for operating the dial part. On the other hand, in the present invention, in the developed state, the entire front elastic flat plate 12 is curved and has a shape like a ridge, so that the front space of the dial portion 38 of the headband 32 can be secured.

  In this embodiment, a part of the rear side 12a of the front elastic flat plate 12 and a part of the front side 13a of the rear elastic flat plate 13 are connected by the bent portion 15, and in the folded state, the front elastic flat plate 12 and In the foldable hat main body 10 in which the rear elastic flat plate 13 is flattened and becomes a cap state when unfolded, on the inner surface side of the front elastic flat plate 12 and the rear elastic flat plate 13, the top of the head near the bent portion 15 is formed. By providing the reinforcing plate members 41 and 41 having a predetermined area, it is possible to enhance penetration resistance and shock absorption of the top of the folding hat main body 10. That is, by providing the reinforcing plate members 41 and 41 on the top of the head where penetration resistance and shock absorption are particularly required to protect the human head from falling objects and the like, the reinforcing plate members 41 and 41 are provided. 41 can ensure penetration resistance and shock absorption. Therefore, the front elastic flat plate 12 and the rear elastic flat plate 13 can be easily changed in shape as compared with the case where the human head is protected only by the penetration resistance and shock absorption of the front elastic flat plate 12 and the rear elastic flat plate 13. It becomes easy to form in thickness and rigidity. As a result, it is possible to provide a foldable cap that can be stored compactly by folding while ensuring sufficient penetration resistance and shock absorption for falling objects and the like to protect the human head.

  According to this embodiment, the front elastic plate 12 for frontal covering molded with a member whose shape is stable in a flat plate state, and the rear elastic plate for frontal covering formed with a member whose shape is stable in a flat plate state 13, the rear side 12a of the front elastic flat plate 12 and the front side 13a of the rear elastic flat plate are connected by a bent portion 15, and the front elastic flat plate 12 and the rear elastic flat plate 13 are flattened by elastic force. In addition, while being bent by the bent portion 15, it is flattened, while the bent inclined portions 15 b and 15 c of the bent portion 15 are brought closer to each other, whereby the front elastic flat plate 12 and the rear elastic flat plate 13 are Since the flat plate state is brought into a bent state against the elastic force to be in a deployed state through the bent portion 15, the unfolded state holding means for holding the unfolded state is provided. And When the holding function is released, it is possible to easily provide a foldable hat that is suitable for avoiding danger, which is a foldable flat shape that is naturally folded by the characteristics of a member that is stable in a flat state. .

  Moreover, the foldable cap is brought into an unfolded state by expanding the front elastic flat plate 12 and the rear elastic flat plate 13 while being bent through the bent portion 15, and is engaged with the locking portion 21e of the unfolded state holding means. By performing an operation to bring the stop pin 23 into the locked state, the whole can be easily and reliably put into a wearable state, and by pressing the pressing portion 21f of the deployed state holding means, If the locked state of the locked pin 23 is released, the front elastic flat plate 12 and the rear elastic flat plate 13 can be easily and reliably returned to the flat fold with the property of returning to the flat plate state.

  In addition, since the front elastic plate 12 for frontal covering and the rear elastic plate 13 for occipital covering are formed by members whose shapes are stable in a flat state, deformation is unlikely to occur and product management is easy, so disaster prevention is possible. Suitable for equipment. In particular, since it can easily be folded in two and thinned, it can be made thin so that it does not appear uncomfortable, such as in a small space, such as in a student's own desk or on the side of the desk. It is possible to store it. Thus, if it can be prepared in close proximity, it is possible to improve the response in situations such as earthquakes that compete for time and to minimize damage. In this case, since the ready-to-use and ready-to-use state is maintained over a long period of time due to the stable characteristics of the shape, management of disaster prevention equipment becomes easy.

  Further, when the front elastic flat plate 12 and the rear elastic flat plate 13 are expanded while being bent via the bent portion 15 to be in the expanded state, the expanded state is held by the expanded state holding means, and is opposite to the folding direction. Since it has a force in the direction, it does not try to close during wearing, and is suitable for wearing in a disaster where there is a risk of falling objects falling. Moreover, the tether is safe because it can be a band or a band having a bendable portion.

  Further, the front elastic flat plate 12 and the rear elastic flat plate 13 are each provided with a reinforcing plate 41 having a predetermined area on the top of the head covering the position corresponding to the top of the head when covering the head near the bent portion 15. By being provided, penetration resistance and shock absorption of the top of the folding hat main body 10 can be enhanced. That is, by providing the reinforcing plate 41 at the top of the head where penetration resistance and shock absorption are particularly required in order to protect the human head from falling objects etc., the reinforcement plate 41 prevents penetration resistance. And shock absorption can be ensured. Therefore, the front elastic flat plate 12 and the rear elastic flat plate 13 can be easily changed in shape as compared with the case where the human head is protected only by the penetration resistance and shock absorption of the front elastic flat plate 12 and the rear elastic flat plate 13. It becomes easy to form so as to have thickness and rigidity. As a result, it is possible to ensure sufficient penetration resistance and shock absorption with respect to falling objects and the like to protect the human head.

  According to this embodiment, the reinforcing plate 41 has a flat plate side plate material 42a disposed on the front elastic plate 12 side or the rear elastic plate 13 side, and has a more flexible side than the flat plate side plate material 42a. The buffer member 42b disposed on the plate is overlapped to ensure the penetration resistance of the reinforcing plate 41 by the flat plate side plate material 42a and the shock absorption by the buffer member 42b. By adjusting the material and thickness of the side plate member 42a and the buffer member 42b separately, it is possible to freely adjust the penetration resistance and the shock absorbing property of the reinforcing plate member 41 at the manufacturing stage. Furthermore, since the flexible buffer member is provided on the head side, the head can be protected from an impact when a fallen object or the like collides. Thereby, the penetration resistance and the shock absorption suitable for the actual situation of the foldable hat main body 10 can be ensured, and safety can be improved.

  According to this embodiment, the reinforcing plate 41 and the front elastic flat plate 12 or the rear elastic flat plate 13 are attached by the surface fastener male bodies 43a, 43b, 43c and the surface fastener female bodies 44a, 44b, 44c. Thus, the reinforcing plate 41 and the front elastic flat plate 12 or the rear elastic flat plate 13 can be detachably formed, and the replacement and maintenance of the reinforcing plate 41 can be facilitated. In addition, a gap 45 is formed between the flat plate side plate 42 a and the front elastic flat plate 12 or the rear elastic flat plate 13 with the reinforcing plate 41 attached to the front elastic flat plate 12 or the rear elastic flat plate 13. As a result, the surface fastener male bodies 43a, 43b, and 43c and the surface fastener female bodies 44a, 44b, and 44c expand and contract in the gap portion 45 so that the impact is absorbed, and the front elastic plate 12 or the rear elastic plate 13 is absorbed. It is possible to absorb the difference in the amount of bending with the reinforcing plate 41 during elastic deformation, to secure the shock absorption against falling objects and the like and to further facilitate the compact storage by folding.

  According to this embodiment, the reinforcing plate 41 is formed in a substantially triangular shape, and the surface fastener male bodies 43a, 43b, 43c are arranged in the vicinity of the respective apex portions. The flat plate 12 or the rear elastic plate 13 is fixed to the front elastic plate 12 or the rear side by being supported by three-point support by the surface fastener male bodies 43a, 43b, 43c and the surface fastener female bodies 44a, 44b, 44c, respectively. The effect of absorbing the difference in the amount of deflection from the reinforcing plate at the time of elastic deformation of the elastic flat plate 13 can be obtained as a higher effect, and the locking state can be prevented from becoming unstable. Further, the two surface fastener male bodies 43a, 43b of the reinforcing plate 41 are attached in the vicinity of the top of the bent portion 15, and the other surface fastener male body 43c is two surface fastener male bodies 43a, 43b. Since the reinforcing plate 41 is attached at a position farther away from the top of the head, the side having the larger area is disposed on the side of the head, and the side having the smaller area is disposed on the portion having a large amount of bending due to folding. Will be. This protects the top of the head, which particularly requires penetration resistance and shock absorption, in order to protect the human head from falling objects, etc., with the reinforcing plate 41 having a large area, and two surface fastener male bodies. 43a and 43b are locked with high strength to ensure the protection of the top of the head, and the amount of bending when the front elastic plate 12 and the rear elastic plate 13 are folded and the amount of bending when the reinforcing plate 41 is folded. Even if they are different, it is possible to prevent a situation in which folding is difficult due to the difference, and to realize compact storage by folding.

  According to this embodiment, the locking means are the hook-and-loop fastener male bodies 43a, 43b and 43c and the hook-and-loop fastener female bodies 44a, 44b and 44c, so that the front elastic plate or The effect of absorbing the difference in the amount of bending with the reinforcing plate at the time of elastic deformation of the rear elastic flat plate can be obtained as an even higher effect.

  In the above-described embodiment, the foldable hat body 10 is formed as a part of the peripheral edge portions of the pair of plate members connected by the bent portions, but is not limited to this, and the foldable hat body The present invention can be applied to any type.

  In the above embodiment, the reinforcing plate 41 is formed by superposing the flat plate side plate 42a formed of a material having high penetration resistance and the buffer member 42b formed of a material having penetration resistance and shock absorption. Although it is configured, it is not limited to this, and a plate material made of one kind of material having both penetration resistance and shock absorption (for example, various elastomers made of urethane resin, silicone rubber, etc.) The structure may be simplified, and the penetration resistance and the shock absorption may be improved by superposing three or more kinds of plate materials formed of different materials on the reinforcing plate material.

  In the above embodiment, the reinforcing plate 41 is supported at three points by the surface fastener male bodies 43a, 43b, 43c and the surface fastener female bodies 44a, 44b, 44c as locking means, but is not limited thereto. Instead, the configuration may be simplified as it is supported by one or two points by a locking means such as a hook-and-loop fastener, or four or more points of the locking means may be provided to increase the locking strength. Furthermore, when attaching the reinforcing plate 41 to the front elastic flat plate 12 and the rear elastic flat plate 13, means other than the locking means may be used. Specifically, for example, when the reinforcing member is formed only from a resilient material (for example, various elastomers made of urethane resin, silicone rubber, or the like), the entire front surface of the reinforcing member 12 and the rear side of the reinforcing member are formed on substantially one side. It is conceivable to simplify the configuration by sticking to the elastic flat plate 13.

  In the embodiment described above, the front elastic flat plate 12 and the rear elastic flat plate 13 are developed by setting the locking portion 21e of the deployed state holding means and the locked pin 23 to the locked or unlocked state. However, the present invention is not limited to this, and the present invention is applied to a foldable hat using any unfolded state holding means as long as it is a mechanism capable of retaining a foldable plate in the unfolded state. May be.

  In the above embodiment, the reinforcing plate 41 has a substantially isosceles triangular shape when viewed from the front. However, the present invention is not limited to this, and the top portion is protected with a reinforcing plate having a large area, and the front elastic flat plate 12 and the rear elastic plate 12 If the amount of bending of the side elastic flat plate 13 when folded and the amount of bending of the reinforcing plate when folded are different from each other as long as it is possible to prevent a situation in which folding is difficult due to the difference, it is an abbreviation other than a substantially isosceles triangle. It may be a triangle or a shape other than a substantially triangle.
