Description

The present invention relates to the structure of an inner protector for boots, and more particularly, to the structure of an inner protector for boots that has excellent puncture resistance.

Recently, the variety of fishing has expanded, and wading, where you go into the water to fish, has become popular, as exemplified by sea bass fishing. When wading, you generally wear waist- or chest-length waders, as you fish with your lower body submerged in water.

There are two types of waders: those with integrated boots and those with separate boots. A boot-integrated type consists of a pair of boots, trousers (up to the waist/chest) with the crotch part waterproofly joined to the upper end of the boots, and the lower end on either side of the upper end of the trousers. It consists of a pair of shoulder belts whose parts are connected (see, for example, Patent Document 1). In addition, the boots with separate type have a sock structure (stocking structure) where the lower part of the inseam part of the trousers continues all the way to the toes, and the boots can be worn over the socks after wearing waders. It has become. In either case, fishing boots with rubber (PVC) soles that are non-slip are used as the boots. (See Patent Document 3).

However, when fishing for sea bass or the like in a tidal flat while wearing waders and boots configured as described above, there is a possibility that the user may be damaged by the tail spines of stingrays or other rays.

In other words, the tails of stingrays (particularly red stingrays, spotted stingrays, narcissistic stingrays, etc.) have fairly long barbed barbs called caudal spines, and when these spines pierce the legs, venom is injected, causing severe pain. And hospital treatment is always required. These spines are quite strong and sharp, and experiments have shown that they can even penetrate aluminum cans. Therefore, it easily penetrates not only the waders but also rubber boots, and they do not function as a protector against the stingray's tail spines.

Therefore, recently, for example, outer type protectors called A-Guard for wading, which attach multiple sets of plate-structured protectors to the outside of boots, and reinforced fibers such as aramid fibers with excellent puncture and cut resistance. An inner type protector is provided in which a large number of layers are polymerized to form a sock structure.

In the case of the above-mentioned outer type protector, if a high-strength synthetic resin molded plate or metal processed plate is used as the protective material of each plate structure, at least the portion covered by the protective material can be effectively protected. However, it is not easy to prepare multiple sets of protective materials having a plate structure with large areas and attach them to the outer circumferential surface of the boots without any gaps, and gaps inevitably occur. Furthermore, the installation itself is troublesome, and the degree of freedom when walking is reduced. Furthermore, during use, a shift occurs between the protective materials, making it impossible to provide reliable protection.

On the other hand, inner-type protectors are made of flexible fiber material and are knitted into a sock structure overall, so they can be worn as is, which solves to some extent the shortcomings of the outer-type protectors. However, because inner-type protectors are merely fiber structures, there are naturally limitations to the thickness of the protective part and the diameter of the fiber mesh, and the reality is that they are unable to adequately handle the sharpness and length of a ray's tail spine.

The present invention was made based on these circumstances, and aims to provide an inner protector for boots that is comfortable to wear and provides reliable protection against the sharpness and length of a stingray's tail spine by dividing the outer surface of the boot into multiple regions according to the outer shape of the foot inserted into the boot, preparing multiple puncture-resistant plate materials that can cover each of the divided regions, and arranging the plate parts of these multiple plate materials using elastic fiber materials so that they overlap with the plate parts of adjacent plate materials by a specified width.

In order to solve the above-mentioned problem, the present invention includes the following effective problem-solving means.

(1) Means for solving the problem of the invention according to claim 1 The means for solving the problem of the present invention has dimensions and shapes corresponding to the dimensions and shape of the inside of the boot to which it is applied, and is inserted and set in a fit state inside the boot, An inner plate for boots into which a foot is inserted in the same set state, which includes a protector body with puncture resistance that protects the outer circumference of the foot to be inserted, an exterior cover that covers the outer peripheral surface of the protector body, and an interior cover that covers the inner peripheral surface of the protector body, and the protector body divides the outer surface into a plurality of regions according to the outer shape of the foot to be inserted, and the plurality of divided regions A plurality of plate materials having a predetermined size and a predetermined shape that can cover each area and have stab-resistant properties, and the peripheral edges of the plate portions of the plurality of plate materials overlap each other with a predetermined width without a gap. It is characterized by being made of stretchable fiber fabric that holds it in place.

The outer surface of the foot is divided into a plurality of regions according to the outer shape of the foot to be inserted into the boot, and a plurality of plates with puncture resistance are used to cover each of the plurality of divided regions. A protector body with high puncture resistance is made of stretchable fiber fabric that holds the peripheral edges of the plate portions of these plurality of plate materials so that they overlap each other with a predetermined width without any gaps, and the outer periphery of the protector body By providing an exterior cover on the surface and an interior cover on the inner circumferential surface, an inner protector for boots with high puncture resistance can be formed, which can be inserted and set into desired boots such as those for waders in a freely attachable and detachable state. I can do it.

In this case, the multiple plate materials are made of the desired plate material that is thin, easily bendable, and has sufficient strength to resist punctures, such as those caused by the tail spines of rays and the teeth of crocodiles. This allows for sufficient puncture resistance to be achieved against the tail spines of rays and the teeth of crocodiles.

The plate materials are arranged and held so that the peripheral edges of the plate parts of each plate overlap each other at a specified width without any gaps, and this arrangement is achieved by arranging them in multiple layers or in a single layer using elastic fiber material depending on the area to be protected. The elastic fiber material that holds the plate materials is made of a strong, sufficiently elastic knit fabric, such as power net, which is made by wrapping nylon around polyurethane and weaving it into a mesh. Therefore, the plate materials, which are thin and easily bent and deformed by themselves, are held in place by the elastic fiber material, allowing them to deform more freely in response to the movement of the feet, and increasing the freedom of movement of the feet when walking, etc.

(2) Means for solving the problem of the invention of claim 2 The means for solving the problem of the invention, in the configuration of the means for solving the problem of the invention of claim 1, includes a plurality of plate materials and holding the plurality of plate materials. The protector body made of stretchable fiber fabric is characterized by being composed of a plurality of protector units configured according to the protection surface of the foot, and by combining the plurality of protector units into one body.

Most common wader boots cover the area below the knee. Accordingly, the inner protector is also configured to cover the lower part of the knee, the shin and calf, the ankle, the instep, and the toes. However, in this case, the shin and calf regions are hardly bent, whereas the ankle region is bent and stretched forward and backward. Furthermore, while the side surfaces of the shin and calf portions are gently curved, the ankle portion has a malleolus on the side surface and forms a partial convex portion. As described above, the external shape and movement of the foot vary depending on the region and are not uniform.

Therefore, even if the outer surface of the foot is protected by dividing the outer surface into multiple regions according to the outer shape of the foot, and using multiple puncture-resistant plate materials of a predetermined size and shape that can cover each of the multiple divided regions, and holding the multiple plate materials with a stretchy fiber fabric so that the peripheral edges of the plate parts overlap each other with a predetermined width without any gaps, the structure needs to be appropriate for the part of the foot.

Therefore, in the solution to this problem, the protector body, which is made up of multiple plate materials and a stretchable fiber fabric that holds the multiple plate materials, is made up of multiple protector units that are configured according to the protective surface of the foot, allowing it to respond appropriately to the different external shapes and movements of the foot depending on the part, and provide a stable protective function.

(3) Solution to the Problem of the Invention of Claim 3 The solution to the problem of the invention of this invention is characterized in that, in the configuration of the solution to the problem of the invention of claim 2 above, the protector units corresponding to both the left and right sides of the foot are composed of multiple overlapping pieces of elastic fiber fabric holding multiple puncture-resistant plate materials of a predetermined size and shape in predetermined positions, while the protector units corresponding to the front and rear sides of the foot are composed of a single piece of elastic fiber fabric holding multiple puncture-resistant plate materials of a predetermined size and shape in place.

The left and right sides of the foot, which are the sides of the shin and calf, are gently curved as a whole, and are wide in the front-to-back direction and large in the up-to-down direction. Therefore, it is necessary to arrange the multiple plate materials in a more appropriate overlapping manner. A single piece of fiber fabric is not sufficient for this. Also, when arranging more than a certain number of plate materials on a single piece of fiber fabric, there is insufficient sewing space. Therefore, the protector unit corresponding to both the left and right sides of the foot is constructed by overlapping multiple pieces of elastic fiber fabric that hold multiple puncture-resistant plate materials of a specified size and shape in specified positions.

In this way, the overall surface has a gentle curve, is wide in the front-back direction, and large in the vertical direction, and can be flexibly conformed to the curved surfaces on both the left and right sides of the foot. It is possible to reliably protect a wide protection surface that is wide and has large vertical dimensions.

On the other hand, the protector unit corresponding to the front and rear surfaces of the foot is composed of a single piece of stretchable fiber fabric that holds multiple stab-resistant plates of a predetermined size and shape. do. The width of the front part of the foot, from the shin to the instep and toes, is relatively narrow in the left and right direction. Appropriate protection can be achieved simply by holding a plurality of plate materials in a mutually overlapping state from above to below, allowing for free bending and stretching. In addition, the width from the back of the calf to the heel, which is the rear surface of the foot, is similarly relatively narrow in the left and right direction. Appropriate protection can be achieved simply by holding a plurality of high-performance plate materials in a mutually overlapping state from top to bottom, allowing for free bending and stretching. Then, by sewing these four sets of protector units each on the left and right, front and back, and integrating them, a protector body that fits properly inside the boot is formed.

In this case, the protector unit that protects both the left and right sides of the foot is, for example, on the rear end side, where both ends of the stretchable fiber fabric that protects the sides of the foot are directly sewn together from the upper end to the lower end. On the other hand, on the front end side, they are indirectly sewn together at a predetermined interval in the left-right direction via a stretchable fiber fabric of a predetermined width. Then, on the rear end side, sew both ends of the stretchable fiber fabric of a predetermined width at a predetermined interval in the left and right direction on the back side of the back end of the multiple sheets of stretchable fiber fabric directly sewn together. By attaching it, a pocket is created between the back of the rear end and the back of the directly sewn together, and in the same pocket, multiple plates of a predetermined size and shape with puncture resistance are attached to one piece of fiber fabric. A rear side protector unit is housed in which the rear side protector units are held in a state where they overlap each other from top to bottom. As a result, the plurality of plates of the rear side protector unit are held in a state where they overlap with the rear ends of the plurality of plates of the left and right side protector units.

At the front end, the front side of the elastic fiber fabric of a specified width is indirectly sewn together with both ends of the elastic fiber fabric at a specified interval in the left-right direction, and both ends of an elastic fiber fabric that is wider in the left-right direction are sewn to a specified position beyond both ends of the elastic fiber fabric to create a pocket between the elastic fiber fabric of the specified width, and a front protector unit is stored in the pocket, which is a single fiber fabric holding multiple puncture-resistant plate materials of a specified size and shape in a mutually overlapping state from above to below. As a result, the multiple plate materials of the front protector unit are held in a state where they overlap the multiple plate materials of the left and right side protector units.

As a result, the entire circumference of the foot inside the boot, except for the sole, is securely covered with multiple (multiple) plates that are highly puncture-resistant.

(4) Means for solving the problem of the invention of claim 4 The means for solving the problem of this invention is the structure of the means for solving the problem of the invention of claim 1, 2, or 3, wherein the stab-resistant performance of a predetermined size and a predetermined shape is provided. A plurality of plate materials are made of metal thin plates each having a predetermined external dimension and a predetermined external shape. It is constructed by placing it between two pieces of strong fiber fabric with large external dimensions and heat sealing the outer periphery.

This configuration allows multiple thin metal plates, which provide reliable puncture resistance, to be wrapped in two high-strength fiber fabrics, forming plate materials that slide easily against each other, and the heat-sealed portions of a specified width on the outer periphery of the thin metal plates can be used as sewing points for the multiple elastic fiber fabrics, allowing them to be sewn as desired.

In addition, the two high-strength fiber fabrics that wrap the metal thin plates act as interference prevention materials between the overlapping metal thin plates, and the metal thin plates do not directly interfere with each other, resulting in higher quietness. In addition, since the fibrous fabric itself that is sewn is stretchable, there is almost no binding force when the fabric is bent, and the fabric has good mobility. Therefore, smooth and quiet bending deformation is achieved. As a result, the entire protector body becomes extremely flexible and flexible. Therefore, the feeling of insertion when inserting the foot is also good.

As the thin metal plate, a metal plate such as SUS304 stainless steel plate, which is thin, easy to bend and deform, and has sufficiently high strength, is used. As a result, sufficient puncture resistance against stingray tail spines, crocodile turtle teeth, etc. can be achieved. In addition, the boots can exhibit sufficient pressure resistance against the high water pressure that acts on the boots for long periods of time when wading.

As the two pieces of high-strength fibrous fabric that wrap the metal thin plates, for example, a fibrous fabric such as polyester fiber, which has high strength and high sliding properties on the surface of the fabric, is used. As a result, stable strength of the plate members themselves and effective movability between the plate members are realized.

(5) Means for solving the problem of the invention of claim 5 The means for solving the problem of the present invention is, in the configuration of the means for solving the problem of claim 3 or 4, in which a plurality of plate members are sewn onto corresponding stretchable fiber fabrics. Attachment is not done by sewing the entire heat-sealed part around the outer periphery of the thin metal plate, but rather takes into account the amount of movement required for each plate, the free overlap with adjacent plate materials, and the relative amount of movement in the overlapping parts. It is characterized by being sewn at a desired position and at a desired length.

As already mentioned, the external shape and movement of the foot differ from part to part and are not uniform. Therefore, even if the external surface of the foot is divided into many regions according to the external shape, and multiple puncture-resistant plate materials of a predetermined size and shape capable of covering each of the many divided regions are sewn to a stretchy fiber fabric so that the peripheral edges of the plate parts overlap each other with a predetermined width without gaps, the plate parts must be sewn appropriately at the desired position and for the desired length, taking into consideration the necessary amount of movement of each plate part of the multiple plate materials, the free overlap of adjacent plate materials, and the relative movement of the overlapping parts.

The solution to this problem in this invention is to address such issues by sewing multiple plate materials to the corresponding stretchable fiber fabric, and instead of sewing the entire heat-sealed portion of the outer periphery of the thin metal plate, it sews the desired length at the desired position, taking into consideration the required amount of movement of each plate, the free overlap of adjacent plate materials, and the relative movement of the overlapping portions.

According to such a configuration, in addition to selecting the external shape according to the part of the corresponding foot protection surface, the required degree of bending and stretching, and the size and shape of the plate material according to the degree of deformation, the desired sewing position, It is now possible to sew with the desired amount of stitching, and the required amount of movement of each plate, free overlapping of adjacent plate materials, and relative movement of the overlapping parts is ensured, allowing for more freedom and appropriate protection. becomes possible.

As a result, the invention of this application makes it possible to provide an inner protector for boots that provides reliable protection without gaps, is highly flexible, and allows the protector as a whole to deform freely. Moreover, no abnormal noise is generated when it deforms, making it extremely quiet. It also provides excellent walking comfort.

Furthermore, in the case of general wader boots, the water pressure that acts on the boot part during wading directly acts on the feet, causing a feeling of pressure such as poor blood circulation in the feet. However, in the case of the invention of this application, the plurality of plate members with high puncture resistance reliably protect the entire undercarriage, so that the undercarriage is reliably relieved from the oppressive feeling caused by such water pressure.

In other words, the inner protector 2 for boots according to the embodiment of the invention of this application is configured, for example, as shown in Figs. 3 to 20, by sewing together a plurality of sets and a plurality of types of protector parts as shown in Figs. 21 to 46, 47 to 52, and 53 to 58, to the outer peripheral surface side and the inner peripheral surface side of the protector body 20 shown in Figs. 18 to 20, respectively, which are integrally configured by sewing together a plurality of sets and a plurality of types of protector parts as shown in Figs. 21 to 46, 47 to 52, and 53 to 58, and covering the entirety by sewing together an outer cover 31 and an inner cover 32, respectively, which realizes a predetermined level or more of rigidity and enhances the shape stability of the inner boot. For the outer cover 31 and the inner cover 32, except for the front covers 31b and 32b described later, a high-strength fiber fabric such as polyester is used, and by setting each to a thickness of a predetermined value or more, the necessary rigidity and shape stability are realized. For these outer cover 31 and the inner cover 32, as an example, a black fabric that matches the black color of the boots is used. In addition, a relatively thicker and stronger fabric is selected for the outer cover 31 than for the inner cover 32.

<Configuration of Exterior Cover 31 and Interior Cover 32: See FIGS. 3 to 17>
The exterior cover 31 is roughly divided into side covers 31a, 31a which cover the left and right side sides of the protector body 20 shown in Figures 18 to 20, a front cover 31b which covers the front side of the protector body 20, a bottom cover 31c which covers the bottom side of the protector body 20, a toe surface cover 31d which covers the toe surface side of the protector body 20, a front upper end cover (reinforcement band) 31e which reinforces the strength of the upper end side of the front cover 31b in the left-right direction and forms a design accent, and a border cover 31f which overlaps the periphery of the opening at the upper end of the waist portion formed by the side covers 31a, 31a, the front cover 31b, and the front upper end cover 31e with the upper ends of each part of the interior cover 32 described later and tapes them together.

In the case of this embodiment, the front cover 31b portion extending from the opening at the upper end of the torso to the tip of the toe at the tip of the instep is made of polyurethane wrapped with nylon, for example, in order to improve flexibility on the front side of the ankle. A strong and sufficiently elastic knit fabric such as power net woven into a mesh is used, and the outer edges of the same fabric are attached to the front edges of the side covers 31a and 31a, respectively. It consists of two sewn pieces of fabric on the left and right, and these two pieces of fabric on the left and right are sewn together at the center of the front part (see Figure 6).

As a result, the fastening strength of the waistband in both the left and right directions is weak, and the opening is prone to widening. Therefore, the front upper end cover (reinforcement band) 31e is provided at the upper end of the front cover 31b at a specified width, as described above, and the front upper end cover 31e is sewn to the front ends of the side covers 31a, 31a, to increase the strength and fastening force of the opening. This allows the waistband and instep to deform freely, while providing sufficient strength and fastening force in the circumferential direction of the waistband. For this reason, the front upper end cover 31e is made of the same high-strength polyester fabric as the side covers 31a, 31a.

On the other hand, the rear ends of the side covers 31a, 31a are sewn together at the center of the rear surface of the waistband from the opening at the upper end of the waistband to the lower end of the heel (see Figure 7).

Further, the outer circumference of the bottom cover 31c is integrally sewn together with the outer circumference of the bottom cover 32c of the interior cover 32, which will be described later, to the lower ends around the feet of the side covers 31a, 31a and the lower ends of the toe cover 31d. (See Figures 3 to 9 and 15 to 17).

On the other hand, the interior cover 32 is made up of left and right side covers 32a, 32a that cover the side protector parts 21, 21 of the protector body 20 (see FIG. 18) described later and correspond to the left and right side covers 31a, 31a of the exterior cover 31, a front cover 32b that covers the front protector part 22 of the protector body 20 and corresponds to the front cover 31b of the exterior cover 31, a bottom cover 32c that corresponds to the bottom cover 31c of the exterior cover 31 and has its outer periphery sewn together with the bottom cover 31c of the exterior cover 31 to the lower end of the foot circumference of the exterior cover side covers 31a, 31a and the lower end of the toe surface cover 31d, a toe surface cover 32d that corresponds to the toe surface cover 31d of the exterior cover 31, and a front upper end cover (reinforcement band) 32e that reinforces the strength of the upper end of the front cover 32b in the left-right direction.

In this embodiment, the front cover 32b on the interior cover 32 side, which extends from the opening at the upper end of the waist to the toe at the tip of the instep, is made of a strong and sufficiently stretchable knit fabric, such as a power net made of polyurethane wrapped with nylon and woven into a mesh, in order to improve the flexibility of the ankle front side, just like the exterior cover 31. Moreover, the fabric is made of two pieces of fabric, one on the left and one on the right, with the outer ends of each of the left and right sides sewn to the front ends of the side covers 32a, 32a, and these two pieces of fabric are sewn together in the center of the front part. Therefore, the fastening strength of the waist in both left and right directions on the inner side is weak, and the opening is likely to widen. Therefore, the front upper end cover (reinforcement band) 32e is provided at the upper end of the front cover 32b, as described above, and the front upper end cover 32e is sewn to the front ends of the side covers 32a, 32a, thereby increasing the strength and fastening force of the opening. This allows the waist and instep sections to deform freely while providing sufficient strength and fastening power for the waist section. For this reason, the front upper end cover 32e is made of a high-strength polyester fabric, just like the side covers 32a, 32a.

<Configuration of protector main body 20: See FIGS. 18 to 58>
For example, as shown in FIGS. 18 to 20, the protector main body 20 includes side protector parts 21, 21 located on both left and right sides and forming a part of the trunk of the protector main body 20, and a front part. It consists of a front side protector part 22 that constitutes a part of the waist part of the protector body 20, and a rear side protector part 23 that is located at the rear and constitutes a part of the waist part of the protector body 20.

The side protector sections 21, 21 each consist of three common protector units, the first to third, 21A to 21C. The front protector section 22 consists of a front cover unit 22A, a fourth protector unit 22B, and a rear cover unit 22C. The rear protector section 23 consists of a fifth protector unit 23A and a rear cover unit 23B.

<Configuration of side protector parts 21, 21: see Figs. 21 to 46>
The side protector parts 21, 21 are each formed by overlapping the first to third protector units 21A to 21C, as is clear from Figures 21 to 23. The first to third protector units 21A to 21C are each formed, as shown in Figures 24 to 32, 33 to 41, and 42 to 46, of the first to third base cloths 24a to 24c cut to fit the shape of the inner side of the boot 11R (11L) in Figure 2, and plate materials P1 to P8, P9 to P16, and P17 to P21 of predetermined sizes and shapes sewn to predetermined positions on the first to third base cloths 24a to 24c, respectively.

The first to third base fabrics 24a to 24c are constructed, for example, by adopting a knit fabric such as the above-mentioned power net fabric having a predetermined mesh diameter that is strong and stretchable in each of the vertical, horizontal and diagonal directions. Each of the plate materials P1 to P8, P9 to P16, P17 to P21 corresponding to each of these first to third base fabrics 24a to 24c is constructed, for example, as shown representatively in Figures 27 and 28 (P1), 29 and 30 (P2), 36 and 37 (P9), and 38 and 39 (P10), by sandwiching a metal (SUS304, etc.) thin plate 25 of a predetermined size and shape between two upper and lower polyester fabrics 26, 26 that are the same shape as the metal thin plate 25 and are a predetermined dimension larger, and by heat-sealing the outer peripheral edges 26a, 26a of the fabrics together using a heat seal material to completely encase the metal thin plate 25. The outer peripheral edges 26a, 26a that are joined together by the heat seal are formed in the sewn portion. The width of the outer peripheral edges 26a, 26a of each plate material P1 to P8, P9 to P16, and P17 to P21 is basically equal in the circumferential direction, but only the uppermost plate material P1 sewn to the first base cloth 24a and the uppermost plate material P9 sewn to the second base cloth 24b have the width of the upper outer peripheral edges 26a, 26a formed to be a predetermined size larger, and are sewn in a manner that matches the upper end of the first base cloth 24a and the upper end of the second base cloth 24b, respectively.

The sewing positions of the plate materials P1 to P8, P9 to P16, and P17 to P21 relative to the base fabrics 24a to 24c are set at sewing positions such that in the overlapping state (three-layer state) of Figure 21 in which three sheets of base fabrics 24a to 24c to which the plate materials P1 to P8, P9 to P16, and P17 to P21 are sewn together as shown in Figures 24, 33, and 42, the plane passing through each of the base fabrics 24a to 24c (24c to 24a) is covered without any gaps by the thin metallic plates 25, 25..., 25, 25..., 25, 25... in each of the plate materials P1 to P8, P9 to P16, and P17 to P21, as shown in Figure 21. The size and shape of the thin metal plates 25, 25..., 25, 25..., 25, 25... in each of the plate materials P1 to P8, P9 to P16, and P17 to P21 are also designed to be large and shaped in a way that allows for easy deformation according to the part of the foot, and that allows for a reliable covering state at the same sewing position.

In this case, the plate materials P1 to P8, P9 to P16, and P17 to P21 can be basically sewn to the front or back of each base cloth 24a to 24c, but in this embodiment, for example, the first base cloth 24a on the foot side and the second base cloth 24b in the middle are sewn to the front side (outside), and the third base cloth 24c on the boot side is first sewn to the back side (foot side) of the third base cloth 24c as shown in FIG. 43, and then superimposed in the same state (same orientation) as the first and second base cloths 24a and 24b in FIG. 42. In this way, the surfaces of both the foot side and the boot side are only the base cloth surface, and there are no unevenness due to the plate materials, so it is easy to finally superimpose the three sheets and sew the above-mentioned exterior cover 31 and interior cover 32. In addition, the surfaces of each cover after sewing the exterior cover 31 and the insert cover 32 are also flat.

In the case of this embodiment, the sewing of the plate materials P1 to P8, P9 to P16, and P17 to P21 to the base fabrics 24a to 24c is performed by sewing the entire circumference of the outer peripheral edge portions 26a and 26a, respectively. However, if there are plate materials that overlap each other by more than a predetermined dimension on the same base fabric, and where they slide relative to each other in opposite directions while overlapping each other, the seams S of the opposing parts should be removed by the necessary dimension. An open surface with a predetermined width is formed so that they can fit freely into each other and can slide relative to each other. As a result, in addition to the elasticity of each base fabric 24a to 24c made of a stretchable knit fabric such as power net, and the flexibility of the metal thin plates 25, 25, etc., each base fabric 24a to 24c surface is The upper plate members P1 to P8, P9 to P16, and P17 to P21 can be more freely deformed and can freely slide relative to each other. As a result, even though a large number of hard thin metal plates 25, 25, etc. are stacked on top of each other, the entire structure achieves flexibility close to that of a fiber material.

That is, in the case of this embodiment, for example, in the arrangement of the plate members in the first protector unit 21A shown in FIG. are in a relationship where they overlap with each other by a predetermined dimension or more.

For example, in the case of plate material P1 and plate material P2, as shown in FIG. 31, no seam S is provided in the predetermined width portion where the lower right end B of plate material P1 and the upper left end A of plate material P2 fit together, allowing free fitting. On the other hand, in the other portions where the plate materials overlap or do not fit together, seams S are provided to securely fix them to the base fabric 24a.

The same applies to the plate material P4 and the plate material P6, and there is no seam S so that the lower end B of the plate material P4 and the upper end A of the plate material P6 can be freely fitted together. On the other hand, seams S are provided in the other portions where the plate members do not overlap or fit each other, and are securely fixed to the base fabric 24a.

Furthermore, in the arrangement of the plate materials in the second protector unit 21B shown in FIG. 33, for example, the lower left end of plate material P9 and the upper right end of plate material P10, the lower right end of plate material P10 and the upper left end of plate material P11, and the lower left end of plate material P11 and the upper right end of plate material P12 overlap and fit together by a predetermined distance or more.

In this case, too, as shown in FIG. 40, at the overlapping and fitting portions B and A of the plate materials P9, P10, P11, and P12, there are provided portions without seams S of sufficient width to allow free fitting. On the other hand, at the other overlapping and non-fitting portions of the plate materials, seams S are provided to securely fasten them to the base fabric 24b.

In the second protector unit 21B, the upper end of plate material P13, the lower left end of plate material P14, the lower right end of plate material P14, the upper left end of plate material P15, the upper right end of plate material P15, and the lower left end of plate material P16. The ends overlap each other by more than a predetermined dimension and fit into each other.

Therefore, in this case as well, as shown in FIG. 41, each of the overlapping and fitting portions B and A of the plates P13, P14, P15, and P16 is provided with a portion without a seam S of a predetermined width, This allows for free fitting. On the other hand, seams S are provided in the other portions where the plate members do not overlap or fit with each other to securely fix them to the base fabric 24b.

In this way, the pair of left and right first to third base fabrics 24a to 24c on which the plate materials P1 to P8, P9 to P16, and P17 to P21 are sewn are superimposed on each other as shown in FIG. The rear end sides are directly sewn together and interconnected as shown in FIGS. 18 and 20. On the other hand, the front end thereof is sewn to both ends of the rear cover unit 22C of the front protector 22 and connected to each other, as shown in FIGS. 18 and 19 (details will be described later).

<Configuration of front protector portion 22: see Figs. 18, 19 and 47 to 52>
Next, the front protector part 22 is composed of, for example, a front cover unit 22A shown in Figures 18 and 19, a fourth protector unit 22B shown in Figures 47 to 52, and a rear cover unit 22C shown in Figures 18 and 19. The fourth protector unit 22B shown in Figures 47 to 52 is stored and held in a protector unit storage pocket 41 (see Figure 19) formed by the front cover unit 22A and the rear cover unit 22C shown in Figures 18 and 19 (see Figure 19).

The front cover unit 22A (see FIGS. 18 and 19) is made of a stretchable knit fabric such as a power unit fabric like the first to third base fabrics 24a to 24c. Further, the rear cover unit 22C is also made of a stretchable knit fabric such as a power unit fabric like the first to third base fabrics 24a to 24c. The front cover unit 22A has the first to third base fabrics 24a to 24c, 24a to 24c, which are overlaid with the side protector parts 21 and 21 on both left and right sides thereof, and a third base fabric 24c on the boot side among the first to third base fabrics 24a to 24c. , 24c are sewn to the inside position by a predetermined width c (see FIG. 19). On the other hand, the left and right sides of the rear cover unit 22C are sewn together at the positions where the front end sides of the first to third base fabrics 24a to 24c are sewn together (see FIG. 19). As a result, a protector unit storage pocket 41 for storing the fourth protector unit 22B is formed between the front cover unit 22A and the rear cover unit 22C. A fourth protector unit 22B (see FIGS. 47 to 49) that covers the front side of the foot is stored in this protector unit storage pocket 41.

For example, as shown in FIGS. 47 to 49, the fourth protector unit 22B is cut to match the shape of the inside of the boot 11R (11L) shown in FIG. 2 from the front to the toe side. A fourth base fabric 28 (see FIG. 48) has a shape in which the dimensions are large and the left and right dimensions decrease toward the bottom end, and on the upper surface of the fourth base fabric 28, as shown in FIG. 47, for example, It is composed of first to fourteenth plate materials P22 to P35 sewn in parallel from the upper end to the lower end with a predetermined overlap width between them. The fourth base fabric 28 is also made of a highly stretchable knit fabric such as a power unit fabric, like the first to third base fabrics 24a to 24c.

The first to fourteenth plate materials P22 to P35 (see FIG. 49) are also basically the first to eighth plate materials P1 to P8 and the second plate materials sewn to the first base fabric 24a described above. Similarly to the first to eighth plate materials P9 to P16 sewn to the base fabric 24b and the first to fifth plate materials P17 to P21 sewn to the third base fabric 24c, Now, a metal thin plate 25 of a predetermined shape is sandwiched between two upper and lower polyester fabrics 26, 26, which have the same shape as the metal thin plate 25 and are larger by a predetermined dimension, and heat sealing material is applied to the peripheral edges 26a, 26a of each other. It has a bag-like structure that is completely enclosed by heat-sealing it together. However, in the case of this fourth protector unit 22B, each shape is formed to be long in the horizontal direction and small in width in the vertical direction so that the front part of the boot can be easily bent and deformed to the front and rear surfaces. . In particular, the fourteenth plate material P35 corresponding to the toe portion at the lowest end (tip of the instep) has a flat upper end, but an arcuate lower end to match the shape of the toe (see Figure 49). ). Moreover, the dimensions of the polyester fabric peripheral edge 26a of the first plate material P22 at the uppermost end are formed to be particularly large, and are sewn together with the upper edge of the fourth base fabric 26 by the above-mentioned hemming cover 31f. .

In this case, the first to fourteenth plate materials P22 to P35 (FIG. 49) are sewn to the fourth base cloth 26 (FIG. 47) in the relationship shown in FIG. 50. That is, the amount of stitching of the first and second plate materials P22 and P23 on the upper end side is sewn to about the upper 2/3 portion as shown on the right side of FIG. 50 to maintain a stable fixed state, but the amount of stitching of the third plate material P24 is about 1/3 of the upper portion, and the amount of stitching of the fourth to thirteenth plate materials P25 to P34 corresponding to the ankle front is about 1/4 of the upper portion, which is approximately horizontal, resulting in a stitching structure that is very easy to bend and deform. This allows the ankle front to bend and stretch freely. The symbols S, S, etc. in FIG. 50 indicate the respective seams. On the other hand, the 14th plate material P35 on the bottom toe side, which does not deform much, is sewn to the base fabric 26 in upper and lower parts almost all around, and the entirety is securely fixed. Furthermore, the tip side of the plate material P35 is sewn to, for example, the lower end of the rear cover unit 22C and secured in place.

In the above configuration, the fourth protector unit 22B in FIG. 47 is formed with a left-right width dimension (from the front upper end to the toe) that corresponds to the dimension b between both left and right ends of the protector unit storage pocket 41 in FIG. 19 described above, and when stored in the protector unit storage pocket 41, it reliably covers (protects) the gap a between the front ends of the side protector parts 21, 21 described above (the gap between the first to third protector units 21A to 21C, 21A to 21C) from the front upper end to the toe.

That is, as is clear from FIG. 19, the width b of the front cover unit 22A, which forms the protector unit storage pocket 41 with the rear cover unit 22C, is greater than the width a of the rear cover unit 22C, and is configured to effectively overlap the first to third protector units 21A to 21C by a predetermined width c, c on the left and right. Therefore, the front part including the rear cover unit 22C part can be sufficiently protected, and the fourth protector unit 22B is only engaged at both the upper and lower ends within the protector unit storage pocket 41, so it is free to move and can be smoothly bent in the front-rear direction.

In this way, in the front protector part 22, the first to third protector units 21A to 21C of the side protector parts 21 and 21, which protect both left and right sides of the foot, are elastic power units with a predetermined width. The rear cover unit 22C is indirectly connected to the rear cover unit 22C made of a knitted fabric such as, etc., and a front cover unit 22A made of a similar knitted fabric is also provided on the front side of the rear cover unit 22C, and both left and right ends of the front cover unit 22A are connected to the third protector. It is sewn to both ends of the front part of the unit 21C. A protector unit storage pocket 41 that can store the fourth protector unit 22B in a freely deformable state is formed between the rear cover unit 22C and the front cover unit 22A. It is stored in a freely deformable state.

This means that this part can freely expand and contract in both the left and right directions, and the inner diameter of the entire waistband can be adjusted to obtain a desired binding force. This allows for fine adjustments to be made according to the size and shape of the user's feet, improving the fit (comfort) when in use.

The width of the front cover unit 22A is greater than the width of the rear cover unit 22C by a specified dimension or more, so that the fourth protector unit 22B housed therein can adequately cover the first to third protector units 21A to 21C and between 21A to 21C.

<Configuration of rear protector portion 23: see Figs. 53 to 58>
Next, as described above, the rear protector portion 23 is made up of the fifth protector unit 23A and the rear cover unit 23B. Here, the configuration of the rear cover unit 23B will be described first.

That is, the rear cover unit 23B is made of a stretchable knit fabric such as a power unit fabric like the first to third base fabrics 24a to 24c. The rear cover unit 23B includes the first to third base fabrics 24a to 24c of the side protector parts 21, 21, which are directly sewn together and interconnected and integrated, as shown in FIG. 20, for example. , 24a to 24c, which have sufficient width and vertical length to cover the connecting part on the rear end side, and whose left and right ends are directly sewn together at the rear end side and are interconnected and integrated. It is sewn at a predetermined width inside position of the boot-side third base fabric 24c, 24c of the first to third base fabrics 24a to 24c, 24a to 24c of the protector parts 21, 21. A protector unit storage area for storing the fifth protector unit 23A is provided between the rear end portions of the first to third base fabrics 24a to 24c, 24a to 24c connected to each other. A pocket 42 is formed. A fifth protector unit 23A (see FIG. 53) that covers the rear side of the foot is stored in this protector unit storage pocket 42.

For example, as shown in FIG. 54, the fifth protector unit 23A is cut to match the shape of the inner rear side of the boot 11R (11L) in FIG. 2 described above, and has an equal width dimension from the upper end side to the lower end side. A strip-shaped fifth base fabric 29 is arranged in parallel from the upper end side to the lower end side with a predetermined overlapping width between them, as shown in FIG. 53, for example, on the upper surface of the fifth base fabric 29. The first to eleventh plate materials P36 to P46 are sewn together. The fifth base fabric 29 is also made of a highly stretchable knit fabric such as power net, like the first to third base fabrics 24a to 24c.

The first to eleventh plate materials P36 to P46 are basically similar to the plate materials P1 to P8 sewn to the first base cloth 24a, the plate materials P9 to P16 sewn to the second base cloth 24b, and the plate materials P17 to P21 sewn to the third base cloth 24c described above, in that a metal thin plate 25 of a given size and shape is sandwiched between two upper and lower polyester fabrics 26, 26 that are the same shape as the metal thin plate 25 but larger by a given dimension, and the edges 26a, 26a are heat-sealed together using a heat seal material to completely encase the plate in a bag-like configuration.

However, in the case of this fifth protector unit 23A, the first to third plate materials P36 to P38 are rectangular plates that are slightly longer vertically, but the fourth to eleventh plate materials P39 to P46 are formed on the rear surface of the boot. Each shape is long in the lateral direction and small in width in the vertical direction so that the bending deformation effect on the front and rear surfaces of the portion is facilitated. In particular, the upper edge 26a of the first plate material P36 on the uppermost side is formed to be larger by a predetermined size, and is sewn together with the upper end of the fifth base fabric 29 by the above-mentioned hemming cover 31f. .

In this case, the first to eleventh plate members P36 to P46 are sewn to the fifth base cloth 29 in such a way that the first to third plate members P36 to P38 are sewn to approximately the upper half of the fifth base cloth 29 as shown in FIG. 56, but the fourth to eleventh plate members P39 to P45 are sewn to approximately the upper third of the fifth base cloth 29, making them very susceptible to bending and deformation. On the other hand, the eleventh plate member P46 at the lowest end is sewn to the base cloth 29 over almost its entire circumference in upper and lower halves, and is securely fixed. The tip of the plate member is sewn to the lower end of the rear cover unit 23B together with the base cloth 29 and is secured thereto.

In the case of the above configuration, the fifth protector unit 23A shown in FIG. 53 is formed to have a left-right width dimension corresponding to the dimension d between the left and right ends of the protector unit storage pocket 42 shown in FIG. 20 described above. (from the upper end of the front part to the lower end of the heel), when stored in the protector unit storage pocket 42, the above-mentioned side protector parts 21, 21 have a predetermined width without the plate material at the mutually connected rear end parts. The part (the part where the plate members P1, P10, P17, P3, P12, and P19 of the first to third protector units 21A to 21C, 21A to 21C do not overlap with each other: see FIG. 21) e from the upper end to the lower end of the heel Cover (protect) reliably.

That is, as is clear from FIG. 20, the width d of the rear cover unit 23B, which forms the protector unit storage pocket 42 between the rear ends of the mutually connected first to third protector units 21A to 21C, 21A to 21C, is sufficiently larger than the predetermined width portion e of the rear ends of the mutually connected first to third protector units 21A to 21C, 21A to 21C where there is no plate material, and is configured to sufficiently overlap the plate material portions of the first to third protector units 21A to 21C, 21A to 21C on the left and right. Therefore, the rear surface portion of the foot can be effectively protected. Moreover, since the fifth protector unit 23A is only engaged at both the upper and lower ends in the protector unit storage pocket 42, it is free to move and can be smoothly bent and deformed in the front-rear direction.

<Features of the inner protector for boots according to the embodiment of the invention of this application>
According to the above configuration, the side protector portions 21, 21, the front protector portion 22, and the rear protector portion 23 are each sewn integrally with one another, so that a large number of highly slidable plate materials P1-P21, P1-P21, P22-P35, P36-P46, each of which is made of highly puncture-resistant metal thin plates 25, 25... and housed in a strong fabric such as polyester, are distributed without any gaps throughout the entire area inside the boot, from the waist portion to the sides, instep, toe, and heel, and each of these plate materials is held by an elastic knitted fiber fabric, forming a highly strong protector body 20 which can be freely deformed.

The outer and inner surfaces of the protector body 20, including the bottom, are covered with an exterior cover 31 and an interior cover 32, which have a certain fabric rigidity that maintains a stable design and shape, and are sewn with high strength to the outer and inner surfaces of the protector body 20.

As a result, the inner protector for boots according to the embodiment of the invention of this application can provide an inner protector for boots that provides reliable protection with no gaps inside the boot, while being flexible overall, allowing the protector as a whole to deform freely, and providing a comfortable fit. In particular, the use of stretchy knit fabric such as the power unit provides high binding strength, resulting in a comfortable fit and excellent walking properties. At the same time, fine adjustments can be made according to the size and shape of the user's feet.

Furthermore, in the case of general wader boots, the water pressure that acts on the boot part during wading directly acts on the feet, causing a feeling of pressure such as poor blood circulation in the feet. However, in the case of the inner protector for boots according to the embodiment of the invention of this application, the plurality of plate materials with high puncture resistance reliably protect the entire undercarriage, so it can be protected from the feeling of pressure caused by such water pressure. will definitely be released.

The plate material that provides the puncture resistance is made of thin metal plates such as stainless steel (SUS304, etc.), so it can adequately handle the tail spines of various rays and the teeth of crocodiles and turtles, and can be used not only as wading boots, but also for a wide range of other purposes such as lake and marsh surveys.
