Description

Technical Field

[0001] The present invention mainly relates to protective gear for protecting oneself from wild beasts such as bears, and particularly relates to protective gear for protecting the head and neck.

Background Art

[0002] In recent years, the number of personal injuries caused by bear attacks (Asiatic black bears, brown bears) has increased rapidly, and the number of casualties has also increased, resulting in an unprecedented serious situation. Previously, it was mainly in mountainous areas, but in recent years, there have been successive damages caused by so-called urban bears that appear in residential areas and urban areas. For example, in mountainous areas, when encountering accidentally during hiking, mountain climbing, or picking wild vegetables, and in residential areas and urban areas, for example, there are cases where children or students are attacked when encountering accidentally while commuting to school.

[0003] In such cases, when a bear attacks a human, it often attacks the head and neck of a person by standing up and swinging its front paws (punching) due to its habits. At that time, it is said that the best defense is to take a protective posture by lying face down or crouching and covering the back of the neck or the head with both hands. However, because the bear is very strong, even then, there may still be deep skull fractures and lacerations such as bites and tears by claws, exposure of the skull, loss of the earlobe, and bleeding from the neck. Therefore, in addition to taking this defensive posture, if there is protective gear for protecting the head and neck, the possibility of avoiding a direct blow and preventing a fatal injury is increased. As such protective gear, conventionally, for example, there is a helmet with a skirt, and this can be used. This covers the head with the helmet body and covers the neck with the skirt hanging down on the lower side, so that damage that would be a fatal injury to the head and neck can be reduced (see, for example, Japanese Patent Application Laid-Open No. 2013-167034).

[0005] However, with conventional protective helmets equipped with neck guards, the need to wear them constantly while walking results in discomfort due to tightness and weight on the head, as well as the head becoming sweaty. Furthermore, even if one tries to carry them, they are bulky, making them difficult to store and carry, and thus lacking portability. Moreover, since bear attacks often occur as accidental encounters, the time required to take out the helmet and put it on the head can lead to delays in initial response and poor responsiveness. In addition, the neck guards are not very effective at preventing claw penetration, resulting in poor puncture protection.

[0006] On the other hand, when going to mountainous areas for activities such as hiking, mountain climbing, and gathering wild vegetables, it is common to carry a backpack or rucksack. Similarly, it is common for children and students to carry school bags or backpacks while commuting to school.

[0007] The present invention has been made in view of these points, and aims to provide protective equipment that is suitable for walking while carrying a backpack, and that is also highly portable and responsive in emergencies. [Means for solving the problem]

[0008] To achieve this objective, the protective device of the present invention comprises an attachment portion that is detachably attached to a backpack worn by a person and whose upper end is positioned above the backpack when attached, and a covering body that is foldable and connected to the upper end of the attachment portion and can be folded when the attachment portion is attached to move to a position that covers one side of the backpack or a position that covers the head and neck of the person, wherein the covering body is formed in the form of a flexible sheet having puncture-resistant and cut-resistant properties.

[0009] In this configuration, it is effective to provide a retaining part that releasably holds the covering in a one-sided covering position. The retaining part prevents the covering from easily flipping upwards. The retaining part releasably holds the covering to a backpack, the human body, or the attachment part. For example, a rope or hook that can be immediately and releasably attached to a backpack or the human body can be used. Alternatively, a magnet may be attached to the covering, and it may be magnetically attached to a magnetic attachment part provided on the attachment part at the one-sided covering position.

[0010] Here, "carrying equipment" refers to any item that is carried on the human body, such as a backpack, school bag, school backpack, carrying frame, carrying ladder, or rucksack.

[0011] Furthermore, puncture resistance refers to resistance to "punctures" caused by bladed weapons or sharp objects. It is also called impact puncture resistance. For example, in a bear attack, it prevents holes from being made by claws. Cut resistance refers to resistance to "slices" caused by bladed weapons or sharp objects. It is also called cut resistance. For example, in a bear attack, it prevents being cut by claws. In other words, this coating possesses a high level of both "impact and puncture resistance" and "cut resistance," as defined in standards such as JIS T8120.

[0012] Furthermore, the description of the covering as a flexible sheet includes not only the case where the entire covering is uniformly flexible, but also the case where it can be partially bent and deformed. The covering can also be formed from a single material or from a combination of multiple materials. Examples are shown below.

[0013] (1) When made from a single material (1-1) Composed of ultra-high molecular weight polyethylene (UHMWPE) fabric This material is formed by weaving ultrafine fibers of this material tightly and densely in multiple axes (multi-directional) to create a sheet. As a single material, it has high cut resistance and impact resistance, and is extremely lightweight. To enhance puncture resistance, it is desirable to weave the fibers as densely as possible or to increase the number of layers. (1-2) Composed of aramid fibers The main properties of aramid fibers are their high elasticity and high strength, with a tensile strength approximately 5 to 7 times that of steel. To enhance puncture and cut resistance, it is desirable to weave the fibers as densely as possible. Furthermore, by creating a felt (nonwoven fabric) structure and laminating felt-like aramid fibers that are randomly intertwined, the absence of a weave provides particularly high resistance to punctures. In addition, by fixing the movement of the fibers with a special resin coating, it is possible to prevent punctures from penetrating into gaps. (1-3) Made of stainless steel mesh (ultra-fine wire) For example, stainless steel wires with a diameter of 0.1 mm or less are woven together in a mesh pattern to form the structure. It offers excellent puncture resistance and physically deflects the tips of claws.

[0014] (2) When manufacturing by combining multiple materials (2-1) Layered formation For example, the outer layer is made of high-density nylon to act as a slippery layer against, say, a bear's claws. The middle layer is formed by laminating the aforementioned ultra-high molecular weight polyethylene (UHMWPE) fibers and aramid fibers. Furthermore, a buffer layer such as high-performance urethane foam is provided in the inner layer to protect the interior from being "crushed" by a bear's blows. (2-2) Flexible plate structure For example, small rigid UHMWPE plates, metal plates, or ceramic tiles can be layered or arranged in a fish-scale pattern and bonded or sewn to a flexible cloth. This can also be covered with cloth. The plates themselves provide puncture and cut resistance, while the connection of the small plates ensures flexibility.

[0015] The size of this protective gear can be determined appropriately to match the size of the backpack. For example, it can be manufactured in various sizes such as small (S), medium (M), large (L), extra-large (LL), and extra-extra-large (3L), and kept on hand so that users can choose the appropriate size.

[0016] Therefore, when attaching this protective gear to a backpack or other carrying device, the attachment part should be positioned so that its upper end is on the upper side of the carrying device. Then, the covering body should be bent relative to the attachment part and positioned on one side of the covering body. In this case, since the protective gear is detachable from the carrying device at the attachment part, by selecting a protective gear of a size that matches the size of the carrying device, it can be used with different types of carrying devices, thereby improving its versatility. Furthermore, because the covering body is flexible, it is easy to fit to carrying devices even if the shape of the carrying device differs, further improving its versatility. In addition, since this protective gear is detachable, it can be stored separately when not in use.

[0017] In this state, the user carries the protective gear on their back and walks. For example, when hiking on a mountain trail. In this case, since the protective gear's covering covers the backpack, it is less bulky compared to carrying a conventional helmet, thus improving portability.

[0018] Furthermore, if, for example, the wearer accidentally encounters and is attacked by a bear while walking, they can lie face down or crouch down, reversing the covering from one-sided to the other-sided position to cover their head and neck. In this case, because the covering is flexible, it can be easily molded to the head and neck. In this state, even if the bear attacks the head or neck with its paws and strikes, the covering has puncture-resistant and cut-resistant properties, so it physically blocks the powerful claw penetration during a bear attack, and also provides strong resistance against tearing (breaking) by the claws, thus reliably protecting the wearer's head and neck. In this case, since the head and neck can be covered simply by reversing the covering from one-sided to the other-sided position, it allows for a speedy response without delay in initial reaction compared to the conventional method of taking out and putting on a helmet each time, providing immediate response and reliable protection for the body.

[0019] Furthermore, as necessary, the covering body is configured to include, at the other side covering position, a central surface portion that covers the back of the head, a front surface portion that is flexibly connected to the central surface portion and can be folded to cover the top of the head, a pair of side portions that are flexibly connected to the central surface portion and can be folded to cover the left and right sides of the head, respectively, and a rear surface portion that is connected to the upper end of the attachment portion and is flexibly connected to the central surface portion to cover the back of the neck.

[0020] In this configuration, it was specified that the covering has a size and shape that enable it to cover the occipital region side, the vertex region side, the side head region with ears, and the posterior cervical region at the other-side covering position. If it can have such a size and shape, the entire covering may be formed so as to bend uniformly. Also, the central facial part, the front facial part, the pair of side facial parts, and the posterior facial part may be configured as a highly rigid sheet using a metal plate or the like, and the front facial part, the pair of side facial parts, and the posterior facial part with respect to the central facial part may be connected so as to be foldable respectively. Further, the central facial part, the front facial part, the pair of side facial parts, and the posterior facial part may be formed as a flexible sheet, and the front facial part, the pair of side facial parts, and the posterior facial part with respect to the central facial part may be connected so as to be foldable respectively. These connections can use flexible materials such as metal hinges, resin hinges, cloth, and fabric. It is also desirable to configure these to have stab-proof and blade-proof properties.

[0021] As a result, when the covering is in the other-side covering position, the central facial part can cover the occipital region, the front facial part can cover the vertex region side, the pair of side facial parts can cover the side head region with ears, and the posterior facial part can cover the posterior cervical region. Thus, it can be said that it becomes container-shaped and can cover the head and neck, so that the covering can be surely performed, and thereby, the head and neck can be surely protected. On the other hand, when the covering is in the one-side covering position, at least the central facial part can cover the front side opposite to the back side of the carrier, the posterior facial part can cover the upper side of the carrier, and the pair of side facial parts can cover the side parts of the carrier respectively. Therefore, the covering of the carrier can also be surely performed.

[0022] In this case, it is effective to provide an operation part on the covering body for bending the front part and the side parts with respect to the central part in the process from the one-side covering position to the other-side covering position. Thus, as described above, for example, when accidentally encountering a bear and being attacked, one lies face down or crouches down, and reverses the covering body from the one-side covering position to the other-side covering position to cover the head and neck of the human body. At this time, when operating the operation part, the front part and the side parts are bent with respect to the central part, and the head and neck can be covered. Therefore, in covering the head and neck, it is possible to respond more speedily and improve the instant response ability.

[0023] In this configuration, if necessary, the operation part is configured as an operation string for bending the pair of side parts with respect to the central part to cover the left and right sides of the temporal region respectively by pulling the outer ends of the pair of side parts forward together with the outer ends of the front part, and bending the front part with respect to the central part to cover the top of the head. Since it can be operated by simply pulling the operation string, the operability is extremely good, and this can also improve the instant response ability.

[0024] This operation string can be configured as a holding part for releasably holding the covering body at the one-side covering position. The operation string is, for example, wound around the human body and tied. Thus, the covering body can be prevented from being easily turned up. In addition, this operation string can also have the function of moving the covering body from the one-side covering position to the other-side covering position by pulling the covering body at the one-side covering position.

[0025] Further, if necessary, the mounting part is configured to include a sheet-shaped main body attached to the back surface of the backpack facing the human body's back, and a cord-shaped fixing body provided on the main body and wound around the backpack to fix the main body to the backpack.

[0026] As a result, when attaching this protective gear to a backpack or other carrying device, the main body of the attachment part is attached to the back of the backpack, and the fastening part is wrapped around the backpack to secure it. In this case, the backpack does not need to have any fastening parts, thus reducing the number of parts. In addition, since it can be secured with a simple operation of wrapping the fastening part around the backpack, the ease of attachment is improved.

[0027] In this case, it is effective to make the fastening body movable and positionable along the vertical direction of the main body. Since the wrapping position of the fastening body can be adjusted, it can be fastened to the optimal position according to the shape of various backpacks, thereby improving versatility.

[0028] Furthermore, if necessary, the main body may be equipped with a cable that wraps around the human body to secure it in place. When the backpack is worn, the cable is wrapped around the body for support. This ensures a secure hold on the attachment point.

[0029] Furthermore, if necessary, the covering is formed by arranging multiple puncture-resistant and cut-resistant plates in a row and attaching them to a flexible sheet. As described above, for example, small rectangular rigid UHMWPE plates, metal plates, or ceramic tiles can be used as plates. As the flexible sheet, it is preferable to form it from the ultra-high molecular weight polyethylene (UHMWPE) fabric described above or a fabric densely woven with aramid fibers. It is easy to manufacture and ensures that the functions and effects of the present invention are reliably exhibited.

[0030] Furthermore, if necessary, a repellent release device is attached to the outer surface of the covering body at the other covering position, which releases an animal repellent with the required force. The repellent releaser uses, for example, a liquid or powdered substance with an odor or irritant that animals dislike, such as capsaicin, as a repellent. This is enclosed in a flattened bag made of thin-film plastic that has the strength to break upon the required impact. Alternatively, the repellent can be microencapsulated (granulated) and then enclosed in the bag.

[0031] This design ensures that when a bear attacks the head or neck with its paws while the person's head and neck are covered by the covering, and the required force is applied, for example, if the claws pierce the bag, the bag will rupture or a hole will be created, releasing the repellent. As a result, the repellent will spray into the animal's eyes and nose, causing intense pain and immediately driving it away, thus ensuring the protection of the person. [Effects of the Invention]

[0032] The present invention provides protective equipment suitable for walking while carrying a backpack, and which is highly portable and responsive in emergencies. Specifically, when attaching this protective equipment to a backpack or other carrying device, the attachment part is detachable from the carrying device. Therefore, by selecting a protective equipment of a size that matches the size of the carrying device, it can be used with different types of carrying devices, thereby improving its versatility. Furthermore, since the covering is flexible, it is easy to fit to the carrying device even if the shape of the carrying device differs, further improving its versatility. Moreover, since this protective equipment is detachable, it can be stored separately when not in use.

[0033] Furthermore, when walking with the protective gear attached to the backpack, the protective gear is less bulky compared to carrying a conventional helmet, as the covering material covers the backpack, thus improving portability. And, if, for example, one accidentally encounters a bear and is attacked while walking, the wearer can turn over or crouch down, reversing the covering material from one side to the other to cover the head and neck. In this case, even if the bear attacks the head or neck with its paws and strikes, the covering material has puncture-resistant and cut-resistant properties, so it will physically block the powerful force of the bear's claws piercing (penetrating) during an attack, and will also provide strong resistance against tearing (breaking) by the claws, thus reliably protecting the wearer's head and neck. In this case, the head and neck of the human body can be covered simply by flipping the covering from one side to the other. Compared to the conventional method of taking out and putting on a helmet each time, this allows for a quick response without delay in initial action, providing immediate responsiveness and reliable protection of the human body.

[Figure 5] This is an exploded view showing a protective device using a covering with a different configuration, according to an embodiment of the present invention. [Figure 6] This figure shows another example of the configuration of a protective device according to an embodiment of the present invention. [Figure 7] This is a partial cross-sectional view showing yet another example of the configuration of a covering body in a protective device according to an embodiment of the present invention. [Modes for carrying out the invention]

[0035] The protective equipment according to embodiments of the present invention will be described in detail below with reference to the attached drawings. As shown in Figures 1 to 4, the protective device T according to the embodiment comprises an attachment part 1 that is detachably attached to a backpack B worn by a person, with its upper end portion 2 positioned above the backpack B when attached, and a covering body 20 that can cover the head and neck of the person. The covering body 20 is foldably connected to the upper end portion 2 of the attachment part 1 and is foldable when the attachment part 1 is attached, so as to be movable to one-sided covering position X (Figure 3(b)) that covers the backpack B, or to the other-sided covering position Y (Figure 4) that covers the head and neck of the person.

[0036] For carrying device B, any item that is carried on the human body is acceptable, such as a backpack, school bag, school backpack, carrying frame, carrying ladder, or rucksack. Figures 3 and 4 show examples of use with a backpack.

[0037] More specifically, the attachment part 1 is composed of a sheet-like main body 3 attached to the back of the backpack B facing the human body, and a cable-like fastening body 4 provided on the main body 3 and wrapped around the backpack B to secure the main body 3 to the backpack B. The main body 3 is made of, for example, cloth and is formed in a long, strip-like shape in the direction of the body axis. The fastening body 4 is composed of a length-adjustable belt 5 and a plastic buckle 6 that releasably connects both ends of the belt 5. On both short edges of the main body 3, there are multiple through holes 7 through which the fastening body 4 can be inserted, provided at predetermined intervals along the longitudinal direction, and the fastening body 4 is attached to the main body 3 by being pulled through a pair of corresponding through holes 7. The fastening body 4 can be moved and positioned along the vertical direction (longitudinal direction) of the main body 3 by selecting any pair of corresponding through holes 7. Since the fastening body 4 is composed of a belt 5 and a buckle 6, the carrying device B does not need to have any fastening parts, thus reducing the number of parts.

[0038] Furthermore, the main body 3 is provided with a cable 10 that is attached to the main body 3 and wrapped around the human body to hold the main body 3 in place. The cable 10, like the fastening body 4, is composed of a length-adjustable belt 11 and plastic buckles 12 that releasably connect both ends of the belt 11, and is attached to the main body 3 by being passed through a pair of insertion holes 7 located in the same position on the main body 3. The cable 10 is generally attached to the lower side of the main body 3 and held at the waist of the human body.

[0039] The covering 20 is formed in the form of a flexible sheet having puncture resistance and cut resistance. Puncture resistance refers to resistance to "punctures" by bladed weapons or sharp objects. It is also called impact puncture resistance. For example, in the bear attack described later, it prevents holes from being made by the claws. Cut resistance refers to resistance to "slices" by bladed weapons or sharp objects. It is also called cut resistance. For example, in the bear attack described later, it prevents being cut by the claws. In other words, this covering 20 possesses a high level of "impact puncture resistance" and "cut resistance" as defined in, for example, JIS T8120.

[0040] More specifically, the covering body 20 is configured to include, at the other covering position Y, a substantially rectangular central surface portion 21 that covers the back of the head, a substantially rectangular front surface portion 22 that is foldably connected to the central surface portion 21 and can be folded to cover the top of the head, a pair of substantially rectangular side portions 23 that are foldably connected to the central surface portion 21 and can be folded to cover the left and right temporal sides, respectively, and a substantially rectangular rear surface portion 24 that is connected to the upper end portion 2 of the attachment portion 1 and is foldably connected to the central surface portion 21 to cover the back of the neck.

[0041] As described above, there are various ways to form the covering 20 into a flexible sheet with puncture-resistant and cut-resistant properties. In this embodiment, multiple plates P are arranged in a row and interposed between sheets S made of flexible woven fabric, and attached to the sheets S with an adhesive or the like. Specifically, plates P are prepared corresponding to the central surface 21, the front surface 22, a pair of side surfaces 23, and the rear surface 24. The size of each plate P is slightly smaller than the size of the respective surface. In the sheets S made of woven fabric that cover the plates P from both sides, the parts of the sheets S facing each other are sewn together. The sewn parts between the plates P form a hinge, making them foldable.

[0042] Examples of plates P include rigid UHMWPE plates, metal plates, and ceramic tiles. Plate P may be formed to be somewhat flexible. Flexible sheets S include, for example, ultra-high molecular weight polyethylene (UHMWPE) fabrics and densely woven aramid fiber fabrics. The materials of plates P and sheets S are not limited to these.

[0043] As shown in Figure 1, the covering 20 is detachably attached to the main body 3 of the mounting part 1 via a plurality of snap buttons 30 (dot buttons). Each snap button 30 consists of a convex member and a recessed member into which it is detachably fitted. Either the convex member or the recessed member is provided at required intervals on the upper end portion 2 of the main body 3 of the mounting part 1, and the other convex member or recessed member is provided at required intervals on the lower end portion 24 of the rear surface portion 24 of the covering 20.

[0044] Furthermore, the covering body 20 is provided with an operating section 40 for bending the front section 22 and side sections 23 relative to the central surface section 21 in the process of moving from one-side covering position X to the other-side covering position Y. The operating section 40 consists of an operating string 41 that, by pulling the outer ends of the pair of side sections 23 forward together with the outer ends of the front section 22, bends the pair of side sections 23 relative to the central surface section 21 to cover the left and right sides of the head, and also bends the front section 22 relative to the central surface section 21 to cover the top of the head. Two operating strings 41 are provided, each formed to a length that can be wrapped around the waist of a person at one-side covering position X of the covering body 20 and fastened together. One end is fastened to the outer end of the side section 23 on the front section 22 side, and the middle is passed through a through hole 42 formed in the outer end of the front end of the front section 22. This operating cord 41 also has the function of moving the covering 20 from the covering position X on one side to the covering position Y on the other side by pulling on the covering 20 at the covering position X on one side.

[0045] Furthermore, the protective device T includes a holding part 50 that releasably holds the covering body 20 in one-sided covering position X. In this embodiment, the holding part 50 is composed of an operating cord 41. By wrapping the operating cord 41 around the waist of the human body and fastening them together, the covering body 20 is releasably held in one-sided covering position X. This prevents the covering body 20 from easily flipping upwards.

[0046] Furthermore, a repellent releaser 60 is attached to the outer surface of the covering body 20 at the other covering position Y, which releases an animal repellent 61 upon impact with a required force. In this embodiment, the repellent releaser 60 is constructed by using a liquid or powdered substance with an odor or irritation that animals dislike, such as capsaicin, as the repellent 61, and sealing it in a flat bag 62 made of thin-film plastic with sufficient strength to break upon impact. It is also possible to microencapsulate (granulate) the repellent 61 and seal it in the bag.

[0047] Furthermore, this protective gear T will be available in several different sizes to match the size of the backpack B. For example, it can be manufactured in various sizes such as small (S), medium (M), large (L), extra-large (LL), and extra-extra-large (3L), and kept on hand so that it can be selected as needed.

[0048] Therefore, when using the protective gear T according to this embodiment, the following procedure is followed. First, it is attached to a backpack or other carrying device B. A protective gear T of a size that matches the size of the backpack B should be selected in advance. As shown in Figure 3(a), the main body 3 of the attachment part 1 is attached so that its upper end 2 is positioned above the backpack B. To attach it, the main body 3 of the attachment part 1 is attached to the back of the backpack B, and the fastening body 4 is wrapped around the backpack B and fastened. In this case, the fastening body 4 can be moved and positioned along the vertical direction of the main body 3, so its position should be adjusted in advance. Since the wrapping position of the fastening body 4 can be adjusted, it can be fastened to the optimal position according to the shape of various backpacks B, thereby improving versatility. In addition, fastening can be done with a simple operation of wrapping the fastening body 4 around the backpack B, improving ease of attachment. In other words, since the protective gear T is detachable from the backpack B at the attachment point 1, by selecting a protective gear T that matches the size of the backpack B, it can be used with different types of backpack B, thereby improving its versatility.

[0049] In this state, the covering 20 is attached to the main body 3 of the mounting part 1 via the snap buttons 30 (dot buttons). In the case of a backpack as a carrying device B, the base end of the shoulder strap may be located towards the center of the container that holds the items. In that case, the shoulder strap can be passed through the gap between the snap buttons 30 and the covering 20 and the main body 3 of the mounting part 1, allowing the covering 20 to be attached to the upper end 2 of the main body 3 without any difficulty.

[0050] Then, as shown in Figure 3(b), the covering 20 is bent relative to the mounting part 1 and positioned on one side covering part X. In this case, since the covering 20 is flexible, it can be easily fitted to the backpack B even if there are differences in the shape of the backpack B, thereby improving versatility.

[0051] In this state, the user walks with the backpack B on their back. For example, when hiking on a mountain trail. In this case, the cable 10 is wrapped around the body for support. This ensures that the attachment part 1 is securely held in place. The operating cord 41, which serves as the holding part 50, is also wrapped around the body and tied. This prevents the covering 20 from easily flipping up. Furthermore, by pulling the operating cord 41 of the operating part 40, the central panel 21 covers the front side of the backpack B opposite to the back, the rear panel 24 covers the top of the backpack B, the pair of side panels 23 each cover the sides of the backpack B, and the front panel 22 covers the bottom of the backpack B. In this case, since the covering 20 of this protective device T covers the backpack B, it is less bulky compared to carrying a conventional helmet, thus improving portability.

[0052] Then, if, for example, a bear is accidentally encountered and attacked while walking, as shown in Figure 4, the wearer can lie face down or crouch down to flip the covering 20 from one-sided covering position X to the other-sided covering position Y, thereby covering the head and neck. Because the covering 20 is flexible, it can be easily conformed to the head and neck. At this time, the operating cord 41 can be released, and the covering 20 in the one-sided covering position X can be pulled with the operating cord 41 to move the covering 20 from the one-sided covering position X to the other-sided covering position Y. Furthermore, if the operating cord 41 is pulled further, the front portion 22 and side portions 23 will be bent relative to the central portion 21, thereby covering the head and neck.

[0053] In this state, even if a bear attacks the wearer's head or neck with its paws and strikes, the covering 20 has puncture-resistant and cut-resistant properties, so it physically blocks the powerful force of the bear's claws piercing (penetrating) during an attack, and also exhibits strong resistance to being cut (broken) by the claws, thus reliably protecting the wearer's head and neck. In particular, when the covering 20 is in the other-side covering position Y, the central surface 21 covers the back of the head, the front surface 22 covers the top of the head, the pair of side surfaces 23 cover the sides of the head where the ears are, and the rear surface 24 covers the back of the neck. In other words, it can form a container-like shape to cover the head and neck, so the covering can be reliably done, and thus the head and neck can be reliably protected.

[0054] Furthermore, in this case, the head and neck of the human body can be covered simply by reversing the covering body 20 from one-sided covering position X to the other-sided covering position Y. Compared to the conventional method of taking out a helmet and putting it on each time, this allows for a speedy response without delay in initial action, providing immediate responsiveness and reliable protection of the human body. In particular, by simply pulling the operating cord 41 of the operating unit 40, the covering body 20 can be reversed from one-sided covering position X to the other-sided covering position Y, and can be transformed into a container-like shape to cover the head and neck, enabling a quick response. Therefore, the head and neck can be covered even more quickly, improving responsiveness. Since it can be operated simply by pulling the operating cord 41, the operability is extremely good, which also improves responsiveness.

[0055] Furthermore, when a bear attacks the head or neck with its paws while the head and neck are covered by the covering 20, and the bear strikes the covering 20, the required force is applied to the repellent releaser 60. For example, if the bear's claws pierce the bag 62, the bag 62 will tear or a hole will be made in the bag 62, and the repellent 61 will be released. As a result, the repellent 61 will spray and adhere to the animal's eyes and nose, causing intense pain and immediately driving it away, thus ensuring the protection of the human body.

[0056] Figure 5 shows a protective device T according to an embodiment, but using a protective covering 20 with a different configuration. This protective covering 20 uses a rectangular flexible sheet S, which is divided into a central surface 21, a front surface 22, a pair of side surfaces 23, and a rear surface 24, and a plurality of small rectangular plates P are arranged in rows in each surface. The material of the plates P and the sheet S is the same as described above. In addition, the operating cord 41 of the operating part 40 is provided in communication with a through hole 43 provided along the outer circumference of the sheet S, and by pulling the operating cord 41, the outer circumference of the sheet S is contracted, making the front surface 22, the pair of side surfaces 23, and the rear surface 24 foldable relative to the central surface 21. Furthermore, another holding part 70 is provided to releasely hold the protective covering 20 in one-sided covering position X. This holding part 70 consists of a magnet 71 attached to the front end of the front part 22 and a magnetic attachment body 72 provided at the lower end of the main body 3 of the mounting part 1, to which the magnet 71 is magnetically attached. At the one-sided covering position X of the covering body 20, the magnet 71 is magnetically attached to the magnetic attachment body 72, thereby holding the covering body 20 in this position. The other configurations are the same as described above.

[0057] As a result, by arranging multiple small rectangular plates P in rows in each section, flexibility and adaptability are increased, making it easier to conform to the surface of the backpack B at one side covering position X, and accommodating backpack B of various shapes. Furthermore, the flexibility at the other side covering position Y makes it easier to cover the head. Other functions and effects are the same as described above.

[0058] Figure 6 shows another example of the configuration of the covering 20. This covering 20 is constructed by overlapping multiple small plates P in a scale-like pattern on its central surface 21, front surface 22, a pair of side surfaces 23, and rear surface 24, and then adhering or sewing them to a flexible cloth. Note that Figure 6 shows only the configuration of the central surface 21 of the covering 20. This allows for greater flexibility.

[0059] Figure 7 shows yet another example of the configuration of the covering 20. In this case, the central surface 21, front surface 22, pair of side surfaces 23, and rear surface 24 of the covering 20 are formed in a three-layer structure. The outer layer 20a (the layer exposed to the outside at the other side covering position Y) is made of high-density nylon to serve as a slippery layer, for example, against bear claws. The middle layer 20b is formed by laminating the above-mentioned ultra-high molecular weight polyethylene (UHMWPE) fibers and aramid fibers. Furthermore, a buffer layer such as high-performance urethane foam is provided in the inner layer 20c. This protects the interior from "crushing" by bear blows. The method of forming the layers is not limited to this.

[0060] Although not shown in the figures, the covering 20 may be constructed as a rigid sheet using a metal plate or the like, with the central surface 21, front surface 22, pair of side surfaces 23, and rear surface 24 being connected to the central surface 21 in a foldable manner. Alternatively, the central surface 21, front surface 22, pair of side surfaces 23, and rear surface 24 may be formed as a flexible sheet, with the front surface 22, pair of side surfaces 23, and rear surface 24 being connected to the central surface 21 in a foldable manner. Flexible materials such as metal hinges, resin hinges, cloth, or woven fabrics can be used for these connections.

[0061] Furthermore, the covering 20 is not limited to a form composed of a combination of multiple materials as shown in the above embodiment, but can be composed of a single material, provided that it is a flexible sheet. In that case, it can be composed of the single material shown below. However, it is not limited to these. (1-1) Composed of ultra-high molecular weight polyethylene (UHMWPE) fabric This material is formed by weaving ultrafine fibers of this material tightly and densely in multiple axes (multi-directional) to create a sheet. As a single material, it has high cut resistance and impact resistance, and is extremely lightweight. To enhance puncture resistance, it is desirable to weave the fibers as densely as possible or to increase the number of layers. (1-2) Composed of aramid fibers The main properties of aramid fibers are their high elasticity and high strength, with a tensile strength approximately 5 to 7 times that of steel. To enhance puncture and cut resistance, it is desirable to weave the fibers as densely as possible. Furthermore, by creating a felt (nonwoven fabric) structure and laminating felt-like aramid fibers that are randomly intertwined, the absence of a weave provides particularly high resistance to punctures. In addition, by fixing the movement of the fibers with a special resin coating, it is possible to prevent punctures from penetrating into gaps. (1-3) Made of stainless steel mesh (ultra-fine wire) For example, stainless steel wires with a diameter of 0.1 mm or less are woven together in a mesh pattern to form the structure. It offers excellent puncture resistance and physically deflects the tips of claws.

[0062] Furthermore, the configuration of the attachment part 1 and the covering body 20 is not limited to those described above and may be modified as appropriate. In addition, although the above embodiment describes an example of protection in the event of a bear attack, the present invention is not limited to protection against bears, and can of course be used for protection against other animals such as other ferocious beasts and birds of prey. Furthermore, the present invention is not limited to protection against animals, and can of course be used to protect the human body in any situation, such as during disasters such as earthquakes or at construction sites. The present invention is not limited to the embodiments described above, and those skilled in the art can easily make many modifications to these exemplary embodiments without substantially departing from the novel teachings and effects of the present invention, and many of these modifications are included within the scope of the present invention.
