Disclosure of the invention Problems to be solved by the invention

 [0005] However, in the above prior art, the cervical vertebra protective band of the first example has an elongated body having a length and a width that surrounds the entire cervical part and is formed of a flexible material. When a large load is applied, there is a problem that the compressive strength in the width direction of the cervical vertebra protective band is insufficient. Therefore, it is impossible to form an opening on the entire surface that reduces the compressive strength, and the air permeability inside and outside the protective band body during use is insufficient, which makes you feel hot during use. There is also a problem that it is inferior to the wearing feeling.

 [0006] In addition, the cervical vertebra protective band of the second example acts on the lower jaw, the lower temporal region, the lower occipital region, and the chest, shoulder, and back by contacting the upper and lower edges of the cervical vertebra protective band. In order to cushion the load, it has a substantially circular cushioning material coated with synthetic leather along the lower edge of the inner sheet and the upper edge of the outer sheet, but the synthetic leather is less hygroscopic and has a lower hygroscopicity. There is a problem that the contact feeling is inferior, such as sweating and uncomfortable feeling due to contact with, etc., and the inner sheet touching the neck to feel uncomfortable. Further, when a large load is applied to the neck, there is a problem that the circular cushioning material is easily displaced in the lateral direction and is easily deformed, and the buffering of the load acting on the lower jaw is insufficient.

 [0007] Therefore, the present invention has been made to solve the above-mentioned problems of the prior art, and its object is to increase the compressive strength in the width direction of the cervical vertebra protective band to protect the cervical vertebra. It is possible to form an opening with a large area in the belt, improve the ventilation around the neck inside and outside the cervical vertebra protective band and improve the feeling of wearing, and further improve the cushioning performance at the upper and lower edges, lower jaw The object is to provide a cervical vertebra protective band excellent in contact feeling with a part or the like.

 Means for solving the problem

 [0008] That is, the present invention relates to a belt-shaped protective band body having a length and a width that surrounds substantially the entire neck of the user, and a use state in which the protective band body is curved along the neck when used. A cervical vertebra protective band having a detachable fixing means to be held on the cervical vertebra, wherein the protective band main body is a laminated body of a core plate and a shock absorber, and the shock absorber is on the cervical side at least on the front and back surfaces of the core plate. A cervical vertebra protective band comprising: a buffer main part attached to one side of the core plate; and a buffer body edge that covers the upper and lower edges of the core plate.

[0009] According to the present invention, the core of the cervical vertebra protective band even when a large load acts on the neck The plate protects the neck, and the load acting on the lower jaw and the like is buffered by the buffer main part and the buffer edge of the buffer of the cervical vertebra protective band. The compressive strength can be increased, and the cushioning performance at the upper and lower edges of the cervical vertebra protective band can be increased. Therefore, for example, even if a soft material that is soft against the skin and inferior in compression resistance is used for the buffer, the entire compression resistance can be maintained by the core plate. In addition, the protective band body can be formed with an opening with a large area to improve air permeability, and the upper and lower edges of the core plate are covered with a cushioning body so that the contact feeling is also good and used. The feeling of time wearing can be made even better.

[0010] It should be noted that a material having rigidity in at least the width direction (short side direction) can be applied as the core plate, such as rubber, plastic, metal, leather, woven fabric, paper, and processed products thereof. The material is formed in a single layer or a plurality of layers made of these materials, and is a plate of equal thickness or unequal thickness formed to a thickness of about 0.; Examples of the material of the shape.

 [0011] On the other hand, examples of the buffer include, for example, soft rubber or plastic, foamed rubber, or a flexible material having excellent buffering capacity made of plastic or the like. The buffer is formed in a single layer or a plurality of layers. An example of the material is a plate-like material having an equal thickness or an unequal thickness formed in a thickness of about 1 to 50 mm. Examples of the material formed in multiple layers include a laminate of soft rubber or plastic, a laminate of rubber or plastic foam, or a laminate of soft rubber or plastic and rubber or plastic foam. Examples include the body.

[0012] Further, the core plate and the buffer body made of the material of these plate-like bodies follow, for example, the shape of a predetermined protective band main body, and, for example, punch cutting processing, saw cutting processing, knife cutting processing, cutting processing, etc. Thus, the outer shape can be formed. In addition, for example, a known adhesive material such as an adhesive, a pressure-sensitive adhesive, and an adhesive finole can be used for adhesion and integration by pressing and / or heating. And the manufacturing method of the laminated body which bonds these together by the sticking processing methods, such as plane press processing and roll press processing, can be illustrated, for example. In addition, when forming an opening part, after shape | molding said laminated body, forming an opening part by a punch cutting process, a saw cutting process, a nigh cutting process, a cutting process etc. can be illustrated, for example. [0013] Further, the form of the protective band body is not particularly limited as long as it has a belt-like shape having a length and a width that surrounds at least the entire neck of the user. A configuration in which the lower part of the user is positioned on the back side of the neck and the central part of the protective band body is positioned on the back side of the neck and is fixed in the vicinity of the lower part of the user In addition to the configuration in which either the left or right side of the protective band body is fixed on the other side with the user's lower jaw positioned, the protective band main body is fixed in a butted manner at the fixed part In addition, the protective band main body that is set to be longer is fixed in an overlapping manner at the fixing portion, and the protective band main body is formed to have the same width, the non-uniform width, or the substantially equal width. And those formed in a curved line.

In the present invention, the buffer body edge is formed so that the buffer body main portion protrudes from the upper and lower edges of the core plate and covers at least the upper and lower edges of the core plate when in use. According to this, the buffer body of the cervical vertebra protective band can be formed integrally with the buffer body main body and the buffer body edge, so that the buffer of the upper and lower edges of the cervical vertebra protective band can be formed with a simple structure. The performance can be improved, and it is possible to manufacture the cervical vertebra protective band at a low cost by simply laminating plate-like material members.

 [0015] It should be noted that the buffer body edge portion formed so that the buffer body main portion protrudes from the upper and lower edge portions of the core plate is at least as long as it covers the upper and lower edge portions of the core plate during use. For example, a form that protrudes approximately 3 to 40 mm from the upper and lower edges of the core plate, preferably a form that protrudes from 5 to 25 mm, and a shock absorber that constitutes the shock absorber edge. For example, it can be projected with a length equal to or greater than the thickness. Also, it is formed to protrude from the edge of the core plate with equal width or unequal width, to protrude from the entire periphery of the core plate, or from the portion where the lower jaw of the core plate is located (for example, the central portion) Examples include a shape that is formed so as to gradually decrease toward the bottom, and a shape that is formed only in the vicinity of a portion where the lower jaw portion of the core plate is located (for example, the central portion). In addition, the shock absorber edge that protrudes from the top and bottom edges of the core plate is approximately 1/3 of the total length near the part where the protective band body lower jaw is located (for example, the center). Examples include those that protrude greatly and those that protrude at different lengths above and below the core plate.

Next, in the present invention, the shock absorber attached to the surface on the neck side of the protective band main body is formed with a recess that extends in the length direction near the center in the width direction and serves as an air passage. Have According to this, since the concave part in the length direction is formed on the surface that contacts the neck when using the cervical vertebra protective band, the shock absorber does not contact the neck on the entire surface of the protective band body, Effective in suppressing sweating around the neck. In addition, it is preferable that this recess is formed over the length of the protective band body, and it functions as an air vent for the air flowing between the neck and the protective band body during use. It is possible to improve the user's wearing feeling by improving the air permeability to the part.

 [0017] It should be noted that, as the shape of such a dent, on the neck side surface of the protective band main body, for example, approximately 1/4 to full width in the vicinity of the central portion in the width direction of the protective band main body; It is good to form the dent part formed by the width | variety over the length direction of a protection belt main body. With such a configuration, the upper and lower portions of the protective band main body contact the neck and maintain a cushioning effect around the neck, while the recess near the center acts as a ventilation path to suppress sweating around the neck. Can do.

 [0018] In addition, the length direction of the indented portion is, for example, formed in the vicinity of a portion (for example, the central portion) where the lower jaw portion of the protective belt main body is located with a length of approximately 1/4 to; 1/2 of the overall length. Alternatively, it may be divided into a plurality of parts over the entire length in the length direction, or may be formed so as to extend over the substantially entire length of the protective band body. Furthermore, as for the depth of the dent portion, a force having a dent level difference of about 2 to 10 mm depending on the thickness of the buffer body can be exemplified.

 In addition, as an example of forming such a recessed portion, for example, the central portion in the width direction of the plate-shaped buffer body is scraped to a certain depth, or the buffer body in the vicinity of the central portion in the width direction is removed. The recess can be formed by a method such as deletion. In addition, the central portion of the buffer body can be physically deformed by heating, pressurizing, or the like, and the recess can be formed by a method of deforming the buffer body by chemical prescription or the like. Furthermore, the formation of the dents by these methods may be exemplified, in which the buffer body in which the dents are formed by a molding die or the like may be created and applied in the manufacture of the buffer body itself.

[0020] In the present invention, the shock absorber attached to the surface on the neck side of the protective band body is divided into two in the width direction of the core plate, and each is attached separately from the core plate. According to this, it is possible to form a recess extending in the length direction in the vicinity of the central portion in the width direction of the protective band main body on the surface that becomes the neck portion side in use. As described above, the dent functions as an air vent for the air flowing between the neck and the protective band body during use. It is possible to improve the user's wearing feeling by improving air permeability. In addition, the buffer body is divided into two in the width direction of the core plate, and the buffer body edge portion that covers the upper and lower edge portions of the core plate and the buffer body main body, which are mounted separately from the core plate. The cushioning effect can be maintained at the upper and lower parts of the protective band main body in contact with the neck portion, which can be configured as described above, and the recess can be formed with a high material efficiency and configuration.

[0021] Even when a plurality of buffer bodies attached to the surface on the cervical side of the protective band main body are laminated, at least any one of these, one or more buffer bodies are core plates. It suffices to be configured so as to be divided into two in the width direction so that each is spaced apart from the core plate to form a recess. For example, the shock absorber on the surface side of the surface in contact with the neck may be divided into two in the width direction, or the core plate side or intermediate buffer may be divided in two in the width direction. In any case, it is only necessary that a recess is formed in the longitudinal direction near the central portion in the width direction of the protective band main body on the surface that becomes the neck side during use. And at least one of these forces, the upper and lower edges of the core plate are sufficient if the one or more buffer bodies are composed of the buffer body main portion and the buffer body edge ends covering the upper and lower edge ends of the core plate. The edge can be covered effectively.

 [0022] In the present invention, it is preferable that the buffer body edge is provided with an opening penetrating the front and back, which acts on the upper and lower edges when the cervical vertebra protective band is used. Since a relatively small load is absorbed when the opening at the buffer edge of the shock absorber is closed and deformed, the feeling of contact with the lower jaw and the like can be softened to enhance the wearing feeling. For larger loads, use force S to increase the cushioning performance at the upper and lower edges of the cervical vertebra protective band.

 [0023] In the present invention, the upper and lower edges of the buffer body edge are formed with uneven portions, which acts on the upper and lower edges when the cervical vertebra protective band is used. Since a relatively small load is absorbed by deformation of the bumps and edges of the shock absorber, the feeling of contact with the lower jaw can be softened to increase the wearing feeling and the load can be increased. On the other hand, the cushioning performance at the upper and lower edge portions of the cervical vertebra protective band can be enhanced.

[0024] In the present invention, the shock absorbers are attached to both the front and back surfaces of the core plate, and are configured to cover the upper and lower edges of the core plate. Upper and lower edges of protective band The buffer performance at the end can be further enhanced, and the entire core plate is covered with the buffer body, so that the entire body is beautiful and a cervical vertebra protective band having a soft touch feeling can be obtained. Further, if the shock absorber is configured to be front and back with respect to the core plate, a cervical vertebra protective band excellent in ease of use can be obtained by eliminating the directionality of both front and back surfaces.

[0025] Next, in the present invention, the core plate is formed so that the thickness is thinner on the left and right sides of the part where the lower jaw of the protective band body is located. According to this, the rigidity at the left and right sides can be controlled while maintaining the rigidity at the position where the lower jaw part of the protective band body is located. The compressive strength can be adjusted on the left and right sides while maintaining the compressive strength in the width direction of the cervical spine, and the cervical vertebra protective band is kept in a curved state around the neck when used on the left and right sides. On the upper side, the left and right sides can be softened so that they can easily become familiar with the neck.

Yes

 [0026] When the lower jaw of the protective band main body is located at the central part of the protective band main body, for example, the thickness of the left and right side portions from the central part of the protective band main body to the left and right ends of the protective band main body The thickness of the core plate may be gradually reduced toward the portion, or only a certain length portion near the left and right end portions of the protective band body may be formed thinner than the thickness of the central portion. These formations are optional, but for example, by the force of thinly forming the left and right side portions of one plate material by a method such as cutting, by laminating a plurality of plate materials having different lengths around the central portion, etc. The core plate with the left and right side parts made thinner than the central part (the part where the lower jaw is located) can be obtained.

[0027] Here, the part where the lower jaw part of the protective band body is located! /, And the length part of about 1/4 to 1/3 of the overall length of the protective band body is the lower jaw part of the user. The right and left sides are not specified, but the core plate is approximately 1/15 to 1/3 of the entire length of the protective band body from both ends of the protective band body. It is preferable to reduce the thickness of the. Further, with respect to the shock absorber attached to the protective band main body, it is preferable to reduce the thickness near the left and right ends of the protective band main body in order to keep the cervical spine protective band curved in use around the neck.

[0028] In the present invention, a thickened portion for increasing the thickness of the core plate is provided at the upper and lower edges of the core plate. According to this, the upper and lower edges of the core plate can be made thicker, so that when a greater load is applied to the neck than when the core plate is made thinner. Thus, the stress acting on the lower jaw and the like by the core plate can be reduced, and therefore the cushioning performance at the upper and lower edge portions of the cervical vertebra protective band can be increased.

[0029] It should be noted that by providing a thickening member for increasing the thickness of the core plate at the upper and lower edge ends of the surface on the neck side of the core plate, the shock absorber attached to this surface has a protective band. A recess similar to the above is formed extending in the length direction near the central portion in the width direction of the main body. The cervical vertebra protective band configured in this way can improve the air permeability between the cervical part and the protective band main body, and can increase the cushioning performance at the upper and lower edge portions of the cervical vertebra protective band. The wearing feeling can be further enhanced.

 [0030] In the present invention, it is preferable that the protective band main body is provided with an opening penetrating the front and back, and the opening is formed over the entire protective band main body. In the present invention, even if an opening penetrating the front and back of the core plate is provided, the compressive strength of the protective band main body can be maintained by the remaining core plate, so the protective band main body can be of any size, shape and arrangement. A large number of openings can be formed. That is, in the present invention, since the core plate is provided on substantially the entire surface of the protective band main body, the protective band main body of the present invention has an opening with a larger area compared to a protective band main body or the like made of only a buffer. The part can be formed. According to this, since it is possible to provide more openings with a larger area over the entire protection belt main body, this makes it possible to improve the ventilation between the neck and the outside air. In addition, it is possible to provide a cervical spine protector that is excellent in compressive strength and lightweight.

[0031] In the present invention, the openings are arranged or opened substantially vertically in the width direction of the protective band main body, and these are arranged in tandem along the length direction of the protective band main body. According to this, the openings are formed by arranging or opening the openings in the vertical direction of the protective band body in the width direction, and further in the length direction of the protective band body. Are arranged in tandem and formed over the length direction to form a plurality of substantially vertical vertical ribs that connect the upper and lower edge portions of the core plate in the width direction with respect to the core plate. . The remaining longitudinal rib-shaped core plate can effectively suppress a decrease in the compressive strength of the protective band main body due to the formation of the opening, so that the opening is formed in a larger area in the protective band main body. Can Become so. In addition, since the opening in the width direction is formed in a substantially vertical direction that is the direction of the compressive strength of the protective band body, the opening is more resistant than the openings formed or arranged in an oblique direction or the like. The formation efficiency of the opening with respect to the compressive strength can be increased. Therefore, the protective band main body of the present invention can be formed with an opening having a larger area than the conventional one, and the excellent breathability can be achieved while maintaining the compression resistance.

 [0032] As for the shape and arrangement of the openings, for example, an opening having an arbitrary shape such as a rectangle, a rectangle, a circle, an ellipse, an oblong shape such as a long hole shape, or a rectangle can be adopted. In order to reduce the stress concentration and maintain the compressive strength of the protective band main body, an opening shape having no corners such as a circle, an ellipse, and an oval is preferable. In addition, for example, an opening array in which a plurality of openings such as a circle and a rectangle are arranged in a substantially vertical shape in the width direction of the protective band main body, an ellipse that is opened in a substantially vertical shape in the width direction, and a long shape. An example is a width direction opening array in which one or a plurality of openings such as a circle and a rectangle are arranged substantially vertically in the width direction of the protective band body. Further, with respect to the length direction, it is better to arrange the arrangement in the width direction in a plurality of columns in the length direction of the protective band body. For example, the lower jaw part of the protective band body is located. May be arranged approximately 1/4 to 1/2 of the entire length in the vicinity of the site (for example, the center), or it may be constructed over the entire length of the protective band body, or such an arrangement. It may be configured in combination with an opening having a configuration different from that of the configuration. In this way, the opening is formed over the entire protective band body.

[0033] Here, as the arrangement of the openings in the length direction in which the above-described core plate is configured in the form of a longitudinal rib, the width of the openings that is the width in the length direction of the openings regardless of the shape of the openings (Opening width) is approximately 5 to 30 mm, preferably 5 to; an opening formed with a size of 15 mm can be exemplified, and the interval width between the opening and the opening forming a plurality of longitudinal rib-shaped widths of the core plate An opening arrangement in which the (opening interval width) is arranged at an interval width of approximately 3 to 40 mm or approximately 5 to 30 mm, more preferably 5 to 20 mm can be exemplified. It is possible to increase the number of vertical ribs formed by arranging them almost uniformly over the entire direction, and to suppress the decrease in compressive strength of the protective band body, so that openings with a larger area can be formed. become. The area of the opening formed in the protective band body should be approximately 5-60% of the surface area of the protective band body. [0034] Further, in the present invention, the opening is formed such that the ratio of the area of the opening to the surface area of the protective band main body is larger on the left and right side portions than the portion where the lower jaw of the protective band main body is located. According to this, it is possible to improve the air permeability between the neck and the outside air in the cervical vertebra protective band, and the compressive strength in the width direction of the protective band body is the part where the lower jaw is located. (For example, the central part) It is large at the left and right side parts, so the compressive strength in the width direction is secured at the central part of the cervical vertebra protective band, and the cervical protective band is curved around the cervical part when used on the left and right side parts. Therefore, the left and right sides are soft and easy to adjust around the neck, and the connectivity of the fixing means can be improved.

 [0035] It should be noted that the opening formed in the protective band main body has a compressive strength in the vicinity of the lower jaw part of the cervical vertebra protective band, and in the vicinity of a portion (for example, the central part) where the lower jaw part of the protective band main body is located. In addition, the opening ratio in the area of approximately 1/4 to 2/3 or approximately 1/3 to 1/2 of the entire length of the protective band body is approximately 5 to 40% or approximately 10 to 30%. Can be exemplified.

 [0036] Further, the compressive strength of the protective band main body is maintained so that it can be easily fitted around the neck during use. The openings near the left and right sides of the protective band main body (near the right and left ends of the protective band main body) It can be exemplified that the aperture ratio in the region of about 1/10 to 1/3 of the entire length of the protective band main body from both ends of the main body is about 15 to 60% or about 20 to 50%.

 [0037] In addition, according to the present invention, it is preferable that a buffer piece for adjusting the height is detachably attached to the edge portion of the buffer body. For example, the height of the cervical vertebra protective band in the width direction can be adjusted by attaching and detaching the buffer piece, and it is possible to adjust the neck height according to the individual skeleton of the user. The height can be easily adjusted by simply attaching and detaching the cushion pieces located at the upper and lower edges.

[0038] The buffer piece can be a band-like piece made of the same material as the above-described buffer body, and the height of the protective band body in the width direction can be adjusted in a range of approximately 0 to 30 mm. It can be provided in the vicinity of the part where the is located (for example, the central part of the protective band body). For example, it can be provided in the central part of the protective band main body with approximately 1/3 of the total length, or can be provided over the entire length. The buffer piece may be formed to have a width for adjusting the height, for example, an equal width, an unequal width, a long taper width, or the like. Can be divided into two parts, etc. The buffer piece is formed on the upper part of the protective band main body. And / or a lower edge portion (buffer body edge portion), which can be detachably attached by attaching / detaching means such as a releasable adhesive, a hook-and-loop fastener, and the like.

 [0039] Further, in the present invention, the protective band main body is composed of a first protective band main body and a second protective band main body, and the two protective band main bodies are detachably attached and the height can be adjusted. According to this, the height of the cervical vertebra protective band in the width direction can be adjusted by attaching and detaching the first protective band body and the second protective band body.

 [0040] Further, in the present invention, the width of the protective band main body is such that the portion in contact with the back of the head when in use is wider than the other portions. Even if this works, it is possible to protect the neck by preventing backward tilting of the neck.

 [0041] Further, in the present invention, the protective band main body is formed so that a portion having a length of approximately 1/4 to 1/3 of the entire length from one end thereof is located in the lower jaw of the user. According to the fact that the detachable fixing means for maintaining the state is provided in the area located in the lower jaw of the user, the elderly who cannot easily turn their hands to the occipital region etc. When a person who has an abnormality in the joint, or an inpatient, etc., use a detachable fixing means that is kept in use in an area located in the lower jaw of the user. Compared with a conventional cervical vertebra protective band in which the central part of the main body is the lower jaw of the user, it can be easily attached.

 [0042] Further, in the present invention, the protective band body is preferably foldable. According to this, since the long cervical vertebra protective band when not in use can be shortened, the cervical vertebra protective band is easily handled. , Storage property, portability and the like can be improved.

[0043] It should be noted that the protective band main body is formed with a divided component section divided into a plurality of parts in the length direction and a hinge portion that foldably connects between the plurality of divided component sections. It is preferable that the hinge part be folded in a short size. The formation of the hinge part is, for example, formed by a processing mark made of a notch process, a notch process, a cutting process or an embossing process performed on the front surface and / or the back surface of the core plate and / or the shock absorber, Examples thereof include a hinge layer laminated on the core plate, and a material such as a deformable holding plastic that can be folded and held. [0044] In addition, according to the present invention, the protective band body is entirely covered with a flexible and removable protective force bar. The protective cover that is soft and touches the skin can improve the sense of contact with the neck, etc. A hygienic state can be maintained.

 [0045] As an example of a protective cover that allows the entire protective band body to be easily inserted and removed, for example, a slide fastener, a hook-and-loop fastener, a hook, and the like can be opened and closed over substantially the entire length of the protective band body on one surface of the protective cover. Can be exemplified.

 [0046] In the present invention, as for the detachable fixing means for holding the protective band main body in its use state, the protective band is not particularly limited as long as it can maintain the protective band main body in its use state. For example, a pair of engaging and disengaging parts such as hook-and-loop fasteners, male and female hooks, and male and female couplers attached to both ends of the main body as described above are attached to both ends of the protective cover. Even if it is a detached part, the above-mentioned pair of engaging / disengaging parts in which one is attached to one end of the protective band main body and the other is attached to one end of the protective cover may be used. One or both of the pair of engaging / disengaging portions are attached to one or both ends of the protective cover, and when the protective band body is folded by being attached to the protective cover, You may make it share with a part or all of the holding means which hold | maintains a main body in the folded state.

 The invention's effect

 [0047] According to the present invention, even if the opening is formed with a large area, a large load acting on the neck acts on the lower jaw and the like while the neck is protected by the core plate of the cervical vertebra protective band. Since the load is buffered at the buffer body main body and the buffer body edge in the buffer body of the cervical vertebra protective band, the compressive strength in the width direction is large, and the cervical vertebra protective band has high buffering performance at the upper and lower edge parts. It is possible to provide a cervical vertebra protective band that can improve the breathability by forming an opening and the like, and is excellent in wearing feeling and contact feeling around the neck when in use.

 BEST MODE FOR CARRYING OUT THE INVENTION

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

 [0051] [First embodiment]

 1 to 3 are views showing a first embodiment of a cervical vertebra protective band according to the present invention. FIG. 1 is a diagram showing a cervical vertebra protective band 10 in the first embodiment. FIG. 1 (a) is a front view showing the deployed state of the cervical vertebra protective band 10. FIG. 1 (b) is a cross-sectional view taken along the line AA in FIG. 1 (a). The cervical vertebra protective band 10 has a band-shaped protective band main body 12 having a length and a width that surrounds almost the entire neck of the user, and a state in which the protective band main body 12 is curved around the neck at the time of use. The hook-and-loop fasteners 14 and 16 (fixing means) are provided for holding and disengaging. The protective band body 12 is a laminated body with the buffer body 20 attached to the surface on the neck side when the core plate 18 is used, and the buffer body 20 is the buffer body main body adhered to the surface of the core plate 18. And a buffer edge 24 that covers the upper and lower edges of the core 18. The buffer body edge 24 is formed so that the buffer body main part 22 protrudes from the upper and lower edges of the core plate 18 and covers the upper and lower edges of the core plate 18 when in use. The buffer edge 24 is bent to a predetermined position in a direction covering the upper and lower edges of the core plate 18. The protective band main body 12 is provided with a protruding end portion 26 protruding from the right end. One of the hook-and-loop fasteners 14 and 16 is attached to the surface of the protruding end portion 26 of the protective band main body 12, and the other is attached to the rear surface of the left end portion of the protective band main body 12.

[0052] It should be noted that the material of the core plate 18 of the protective band body 12 is formed by curving the entire body around the neck portion. Appropriate flexibility that can be worn on the neck, rigidity that does not easily deform when a large load is applied to the neck during use, and excellent compression resistance in the width direction Materials formed into a plate shape are preferred, for example, plastic plates, rubber plates, plastic plates with a foaming ratio of 3 times or less, or laminated plates made of two or more kinds of plate materials selected from these. It is determined appropriately in consideration of the required properties such as compression resistance.

 [0053] Further, the specific material of the core plate 18 is not particularly limited. For example, polyethylene, polypropylene, polycarbonate, polyamide, ABS (Atalylonitrile butadiene styrene), PET (Polyethylene terephthalate), PBT (Polybutylene terephthalate) ), Ethylene vinyl acetate copolymer, olefin-based thermoplastic elastomer, syndiotactic 1,2-polybutadiene, polyurethane, and other plastics, polyethylene-based, polypropylene-based, polystyrene-based, polyamide-based, polyester-based resins Deformation-holding plastics obtained by stretching such as urethane, polyamides, polyesters, styrenes, vinyl chlorides, fluorines, silicone resins, etc., and synthetic rubbers, natural rubbers, etc. Beam, include and so on.

 [0054] The thickness of the core plate 18 of the protective band body 12 is appropriately determined in consideration of the required characteristics such as compressive strength and the feeling of wearing, and the force varies depending on the material used. The thickness is in the range of 10 mm or less, preferably 0.5 mm or more and 5 mm or less, more preferably 0.5 mm or more and 4 mm or less. The core plate 18 in the present embodiment is a plate-like body made of polyethylene resin, and is roughly formed to have a thickness of 1 mm, a width of 7 cm, and a total length of 51 cm, and has sufficient compressive strength in the width direction. Yes.

 [0055] Besides, the core plate 18 is formed to have a substantially equal width as shown in the figure, and the width of the length portion of 1/4 to 1/2 of the total length in the vicinity of the central portion generally located in the lower jaw portion. The height in the direction may be smaller than that of the other part, or the upper and lower edge portions of the core plate 18 of this part may be formed thinner than the other part. Compared to other parts, the material of the core plate 18 constituting this part may be replaced with a soft resin, and in particular, it is possible to improve the feeling of contact with the discomfort felt by the lower jaw, chest and the like.

[0056] Next, the material of the buffer body 20 of the protective band body 12 includes a buffer body main part 22 that mainly buffers and protects around the neck part when a large load is applied to the neck part in use, and the core plate 18 Top and bottom edge of It is preferably made of a material having a buffer body edge portion 24 for buffering and protecting the lower jaw portion and the like that comes into contact with the material, and having sufficient buffer performance at these portions. Examples of these materials include a plastic foam plate (foamed plastic plate), a soft rubber plate, a soft rubber foam plate, a gel material plate, a gel material foam plate, or two or more kinds of plate materials selected from these. The laminated board etc. which become.

 [0057] Further, when a plastic foam plate is used for the buffer body 20, for example, a foam plastic plate having a foaming ratio of 2 times or more is preferred! /, But if the foaming ratio is too low, the cushioning performance is increased. However, if the foaming ratio is too high, it will soften and improve the wearing feeling but reduce the buffering performance. Therefore, it is more preferable to use a plastic foam plate with an expansion ratio of 5 to 80 times for the buffer body 20, and it is more preferable to use a plastic foam plate with an expansion ratio of 10 to 50 times. It has excellent performance and shock-absorbing performance that makes it preferable to feel soft when it comes into contact with the neck or lower jaw.

 [0058] Further, in order to further improve the feeling of wearing, it is preferable that the buffer body 20 be a plurality of laminated bodies made of plastic foam plates. In this case, the neck side is a plastic foam plate having a high expansion ratio (for example, 20 to 80 times or 30 to 50 times), and the core plate 18 side is lower than the neck side (for example, the expansion ratio is low). (Foaming ratio: 5 to 40 times or 10 to 30 times) If a foaming plate made of plastic is arranged, soft contact feeling can be obtained at the neck and lower jaw, etc. Since the performance can be obtained, the cervical vertebra protective band 10 having a better cushioning performance and a better wearing feeling can be obtained.

[0059] Here, when the buffer body 20 as described above is laminated with a plurality of plastic foam plates having different expansion ratios, the plastic foam plate with a high expansion ratio on the neck side can be detachably attached. It can also be configured. A plastic foam plate with a high expansion ratio on the cervical side can soften the sensation of contact on the cervical side, but it may be in close contact with the cervical region and may be hot. It is preferable that it can be attached and detached according to the sense and usage. Furthermore, the plastic foam plate with a high expansion ratio on the neck side is not placed on the entire surface of the shock absorber 20 but only in the vicinity of the shock absorber edge 24 of the shock absorber 20 that contacts the user's lower jaw, etc. In this case, the feeling of hotness around the neck can be reduced. [0060] Here, the material of the buffer body 20 is not particularly limited, but a soft rubber or plastic material such as soft rubber, foamed rubber, plastic, or the like, which is excellent in buffer capacity, is preferred. For example, polyethylene, ethylene vinyl acetate copolymer, urethane, polystyrene, silicone foam plastic foam, synthetic rubber, natural rubber foam, silicone gel, polymer gel substance such as urethane, rich in flexibility Urethane rubbers, vulcanized rubbers, elastomeric resins such as urethane-based, silicon-based, and polyamide-based rubbers, etc., and examples of the resins listed above or composites thereof. These shock absorbers 20 are relatively thin and / or cover the side surface and both upper and lower edges of the plate-like core plate 18 to prevent a feeling of discomfort during use, and to reduce the impact that is applied during use.

 [0061] The thickness of the buffer body 20 of the protective band main body 12 is preferably in the range of 1 mm or more and 50 mm or less. In the present embodiment, a plate-like cushioning body with a thickness of 8 mm made of a plastic foam with a foaming ratio of 30 times made of polyethylene resin is adopted over the entire surface, and the whole is light weight and has excellent electrode alignment and properties. Get ready!

 [0062] The buffer body 20 of the protective band body 12 includes a buffer body main part 22 that is adhered to the surface of the core plate 18, and a buffer body edge 24 that covers the upper and lower edges of the core plate 18. The shock absorber edge 24 is a force formed so that the shock absorber main portion 22 protrudes from the upper and lower edges of the core plate 18. The shock absorber edge 24 is the thickness of the core 18 The force varies depending on the height. It only needs to protrude from the upper and lower edges of the core plate 18 to a length of about 3 to 40 mm. The edge can be sufficiently covered, and the shock acting on the lower jaw can be sufficiently buffered. The buffer body 20 in the present embodiment is configured to protrude from the upper and lower edges of the core plate 18 with a length of approximately 10 mm.

[0063] In the present embodiment, the buffer body edge 24 of the buffer 20 is bent in advance to a predetermined position in a direction covering the upper and lower edges of the core plate 18; The end 24 may be formed in a straight line simply by extending the buffer main body 22 as it is. In this case, since the shock absorber edge 24 is located on the inner surface side around the neck of the core plate 18 in use, the shock absorber edge 24 that is softer than the core 18 is caused by contact pressure with the neck during use. It is bent very naturally so as to cover the upper and lower edges of the core plate 18, and this shape force S is applied to hold it. It is.

 Further, in the present embodiment, the buffer body 20 of the protective band body 12 may be provided on both surfaces of the force core plate 18 provided on one side of the core plate 18. Similarly, the buffer body main part 22 and the buffer body edge part 24 constituting the buffer body 20 are integrally formed, but the buffer body main part 22 and the buffer body edge part located above and below the core plate 18 are formed. The portion 24 may be configured as a shock absorber 20 that is provided in the upper and lower portions with the same material and the same size, or as a shock absorber 20 provided separately with a different material and a different size. In this case, the upper and lower shock absorbers 20 are configured. The buffer body main part 22 and the buffer body edge part 24 may be configured such that the upper and lower parts are arranged separately or separated from each other.

 [0065] Further, the laminated body of the core plate 18 and the buffer body 20 in the protective band main body 12 is such that the core plate 18 and the buffer body 20 are welded by adhesion using an adhesive or the like, or by melt adhesion such as solvent melting or heat melting Adhesion using adhesive, etc., sewing by sewing, or adhesion by means of engagement / disengagement means such as hook-and-loop fasteners. In the present embodiment, the core plate 18 and the buffer body 20 are bonded with a synthetic rubber adhesive.

 [0066] In order to make the cervical vertebra protective band 10 curved in use around the neck during use, the upper center in Fig. 1 (a) is the approximate center of the lower jaw of the user. According to the position, the center of the lower side is aligned vertically so that the center of the upper chest is approximately the center position of the upper chest of the user. After wrapping around the neck so that it becomes the side surface, the hook-and-loop fastener 14 provided on the projecting end 26 is fixed to the other hook-and-loop fastener 16 at the rear position of the neck of the user. Install and use. Here, as examples of other fixing means, fixing means such as a male and female hook or a male and female coupler can be used.

 [0067] In the cervical vertebra protective band 10 of the first embodiment, the protective band main body 12 has the core plate 18 having excellent compression strength in the width direction, and therefore the opening that penetrates the front and back surfaces is entirely formed. It can be provided over a large area, and its compressive strength can be maintained. Therefore, air permeability during use can be secured. Further, the cervical vertebra protective band 10 in which the protective band main body 12 is covered with a flexible and removable protective cover can also be used.

As described above, according to the first embodiment, even when a large load acts on the neck, The neck is protected by the core plate 18 of the vertebra protective band 10, and the load acting on the lower jaw is buffered by the buffer main body 22 and the buffer edge 24 of the buffer body 20 of the cervical vertebra protective band 10. Therefore, the compressive strength in the width direction of the cervical vertebra protective band can be increased, and the cushioning performance at the upper and lower edge portions of the cervical vertebra protective band can be increased.

 [0069] Further, since the buffer body 20 of the cervical vertebra protective band 10 can integrally form the buffer main body 22 and the buffer body edge 24, the protective band body 12 is a buffer body made of a plastic foam plate. The cervical vertebra protective band according to the first embodiment can be manufactured at a low cost because it has a simple structure composed of 20 and a plastic core plate 18 and laminated and bonded.
