[Figure 14] FIG. DETAILED DESCRIPTION OF THE INVENTION
[0013] Hereinafter, one embodiment of the present invention, which is a chest protector 10, will be described with reference to FIGS. FIG. 1 shows a front view of protector 10. Here, the orientation of protector 10 and each of its constituent members will be defined as follows: the up-down direction of protector 10 relative to the orientation shown in FIG. 1 is referred to as the up-down direction. The left-right direction in FIG. 1 is referred to as the left-right direction or width direction of protector 10, respectively; the side shown in FIG. 1 and the direction in which it is located are referred to as the front, front, or forward; and the opposite side (the side facing the user's chest) is referred to as the back, rear, or rear. Therefore, the front view in FIG. 1 is a view of protector 10 seen from the front, the back view in FIG. 2 is a view of protector 10 seen from the rear, the plan view in FIG. 3 is a view of protector 10 seen from above, and FIG. 4 is a view of protector 10 seen from the right.
[0014] As shown in Figures 1 and 2, the protector 10 has a generally trapezoidal shape when viewed from the front and rear. The protector 10 includes a protector body 20 made of synthetic resin and two mounting portions 30, one on each side. A portion of each mounting portion 30 is exposed from the front of the protector body 20. The protector 10 has a frame portion 40 that runs continuously around the periphery to ensure strength. The frame portion 40 has a polygonal void portion on its inner edge. The void portion is formed to penetrate the frame portion 40 from front to back, thereby reducing the weight of the frame portion 40. The protector 10 also has a front plate portion 50 on the front side of the inside surrounded by the frame portion 40, and a rear plate portion 60 on the rear side.
[0015] As shown in Figures 3 and 4, the protector 10 is formed with a substantially uniform thickness. The lower portion of the protector 10 has a curved shape with both left and right ends pointing backward in the plan view shown in Figure 3. This conforms to the shape of the human chest and is intended to reduce the gap between the chest and the rear surface of the protector 10 when the protector 10 is worn on the chest. As shown in Figure 4, the protector 10 has a curved shape that is slightly convex from both ends in the vertical direction toward the center in the same direction in a side view. This also conforms to the shape of the human chest and is intended to reduce the gap between the chest and the rear surface of the protector 10 when the protector 10 is worn on the chest. The shapes of the front and rear surfaces of the protector 10 are partially omitted in Figures 3 and 4.
[0016] As shown in Fig. 5, the protector 10 is composed of a front member 10a and a rear member 10b that are divided into two parts, front and rear, and is formed by assembling the front member 10a and the rear member 10b to form the protector 10 shown in Figs. 1 to 4. The front plate 50 and the mounting portions 30 located on the front surface of the protector 10 are provided on the front member 10a, and the rear plate 60 located on the rear surface of the protector 10 is provided on the rear member 10b.
[0017] The configuration of the protector 10 will be described below by explaining the configuration of the front member 10a and the rear member 10b. Regarding the front member 10a Fig. 6 shows a front view of the front member 10a, and Fig. 7 shows a rear view of the front member 10a. The portion of the front member 10a excluding the mounting portion 30 constitutes the protector main body 20. Furthermore, the rear surface of the front member 10a shown in Fig. 7 is located inside the protector 10 when the front member 10a and the rear member 10b are assembled together, and is therefore difficult to see from the outside of the protector 10 shown in Figs. 1 to 4.
[0018] As shown in Figures 6 and 7, a front frame portion 40a that constitutes the frame portion 40 is formed around the periphery of the front member 10a, and multiple locking walls 41a are formed around the outer edge of the front frame portion 40a. The locking walls 41a form locking portions. Each locking wall 41a is a thin plate recessed inward from the periphery of the front frame portion 40a. The front frame portion 40a also has a polygonal front gap 42a at its inner edge. The front gap 42a forms a gap. The front gap 42a is formed to penetrate from front to rear, thereby reducing the weight of the front frame portion 40a. In Figures 6 and 7, only a portion of the front gap 42a is indicated by a reference numeral. The front surface of the front member 10a, surrounded by the front frame portion 40a, is formed with a front plate portion 50 and a covering portion 70 surrounded by the front plate portion 50. The front plate portion 50 is plate-shaped with curved surfaces that curve in the left-right and up-down directions. The covering portion 70 covers each mounting portion 30 while leaving a portion of each mounting portion 30 exposed. The front frame portion 40a, the front plate portion 50, and the covering portion 70 are integrally formed from resin. Each mounting portion 30 is long vertically when viewed from the front, and two mounting portions 30 are arranged parallel to each other.
[0019] A partially enlarged view of the front plate 50 is shown in the upper right of Figure 6. The front plate 50 has a plurality of air vents 51 formed over its entire surface, penetrating the front plate 50 in the front-to-rear direction. In the enlarged view, the air vents 51 are shown as white circles. Each air vent 51 has a minimum diameter portion on the front side in the hole formation direction (front-to-rear direction), and is drum-shaped with a diameter that gradually increases rearward and forward from there. In addition, the front opening periphery of each air vent 51 is chamfered in an R shape, while the rear opening periphery is not chamfered. The axes of each air vent 51 are parallel. Note that in the enlarged view, only some of the air vents 51 are marked with reference numerals.
[0020] As shown in the enlarged view, the ventilation holes 51 formed in the front panel 50 are grouped into ventilation hole units 52, each consisting of a certain number of ventilation holes 51 arranged in a hexagonal pattern. These ventilation hole units 52 are arranged in a tortoiseshell pattern on the front panel 50. In the honeycomb-shaped areas formed between the ventilation hole units 52, blind holes 53 of approximately the same diameter as the ventilation holes 51 are formed at the same pitch as the ventilation holes 51. In the enlarged view, the blind holes 53 are illustrated as colored circles. Therefore, the ventilation holes 51 and blind holes 53 are evenly spaced on the front surface of the protector 10 and the front member 10a that constitutes it, creating a sense of visual unity. On the rear surface of the front panel 50 where the blind holes 53 are formed, a front reinforcing portion 80a is formed along the blind holes 53, forming a reinforcing portion. Note that in the enlarged view, only some of the blind holes 53 are marked with reference numerals.
[0021] 7 shows a rear view of the front member 10a, in which the front reinforcement portion 80a is integrally formed of resin with the front frame portion 40a, the front plate portion 50, and the covering portion 70. The front of the front reinforcement portion 80a is connected to the rear surface of the front plate portion 50, closing the front of the front reinforcement portion 80a, while the rear of the front reinforcement portion 80a is open. Because the ventilation holes 51 are formed in positions on the front plate portion 50 behind which the front reinforcement portion 80a is not located, the hexagonal ventilation hole units 52 are formed in a tortoiseshell shape when the front member 10a is viewed from the front (upper right in FIG. 6).
[0022] 7, the honeycomb-shaped walls that make up the front reinforcement portion 80a extend in the same direction, and opposing honeycomb-shaped walls are parallel throughout the entire front reinforcement portion 80a. The front reinforcement portion 80a extends perpendicular to the rear surface of the front plate portion 50 near the center of the front member 10a, but extends non-perpendicular to the rear surface of the front plate portion 50 at the left and right ends of the lower part of the front member 10a. The front reinforcement portion 80a is formed with a plurality of positioning pins 81a that extend rearward from its rear end and form a positioning portion.
[0023] As shown in FIG. 7, the polygonal front gap 42a in the front frame 40a is formed by removing weight from the inside of the honeycomb-shaped wall, extending the front reinforcement 80a. The maximum diameter of each vent hole 51 is smaller than the length between the opposing surfaces of the honeycomb-shaped wall that constitutes the front reinforcement 80a and is smaller than or equal to the thickness of the wall. The maximum diameter of each vent hole 51 is smaller than the length of the engagement wall 41a (the length in the circumferential direction of the front frame 40a) and the thickness of the front plate 50. The maximum area of the opening of each vent hole 51 is smaller than the minimum area of the front gap 42a. The thickness of the front plate 50 is smaller than the height of the front reinforcement 80a in the front-to-rear direction. The thickness of the honeycomb-shaped wall that constitutes the front reinforcement 80a is larger than the maximum diameter of the vent hole 51.
[0024] As shown in Figures 3 and 4, the covering portion 70 is continuous with the front plate portion 50 and is formed to bulge forward. As shown in Figure 4, the front surface of the covering portion 70 is flat. In the front member 10a, three locations in the vertical direction of each mounting portion 30 are exposed portions 71 where the mounting portion 30 is not covered by the covering portion 70. Therefore, the front member 10a has a total of six exposed portions 71.
[0025] As shown in Fig. 6, each exposed portion 71 has an oval shape when viewed from the front. At the center of each exposed portion 71, a part of the base material 31 of the attachment portion 30 and a male button 32, which is attachment means that allows the protector main body 20 to be attached to a garment 200 (see Fig. 14) worn by a wearer, are located. As shown in Fig. 7, a front reinforcing portion 80a is formed between the exposed portions 71 of each attachment portion 30 of the front member 10a. Also, as shown in Figs. 3 and 4, a part of the male button 32 is located so as to protrude forward from the covering portion 70.
[0026] FIG. 8(a) shows a front view of the attachment portion 30, and FIG. 8(b) shows a side view. As shown in these figures, the attachment portion 30 is composed of an oval-shaped base material 31 and male buttons 32 fixed at three longitudinal positions on the base material 31. The base material 31 is formed from a rigid yet flexible material such as synthetic resin or fiber. The male buttons 32 are snap buttons made of metal or resin and are fixed to the front and rear of the base material 31 by caulking. Furthermore, the upper and lower ends of the base material 31 are formed with retaining holes 33, and elliptical holes 34 elongated in the width direction are formed between each pair of male buttons 32 on the base material 31. Two attachment portions 30 are formed integrally with the front member 10a by insert molding. The elliptical dashed line shown for the covering portion 70 in FIG. 6 indicates the outer periphery of one attachment portion 30 covered by the covering portion 70. The outer periphery of each attachment portion 30 is covered by the covering portion 70 on both the front and rear surfaces.
[0027] FIG. 9 shows a schematic end view of line AA in FIG. 6. The top of the figure is the front (the side in FIG. 6), and the bottom is the rear (the side in FIG. 7). As shown in the figure, both widthwise ends of the mounting portion 30 are covered from the front and back by covering portions 70, with an exposed portion 71 located in the center, and the male button 32 is located in this exposed portion 71. The area of the exposed portion 71 is slightly larger on the rear surface (the side in FIG. 7). Furthermore, in the covering portion 70, mounting holes 72 are formed in the front and rear at positions that overlap with the hook holes 33 at the top and bottom ends of each covered mounting portion 30, and communicate with the hook holes 33. In the covering portion 70, support holes 73 are formed in the front and rear at 12 locations on the outer periphery of each covered mounting portion 30, exposing the mounting portion 30. These mounting holes 72 and support holes 73 are formed in relation to the insert molding of the mounting portion 30 and are not related to the function of the protector 10.
[0028] Regarding the rear member 10b Fig. 10 shows a rear view of the rear member 10b, and Fig. 11 shows a front view of the rear member 10b. The entire rear member 10b constitutes the protector main body 20 and is located at the rear of the protector 10. The front surface of the rear member 10b shown in Fig. 10 is located inside the protector 10 and is therefore difficult to see from the outside of the protector 10.
[0029] As shown in Figures 10 and 11, a rear frame portion 40b that constitutes the frame portion 40 is formed on the periphery of the rear member 10b, and multiple locking claws 41b are formed to protrude forward from the outer edge of the rear frame portion 40b. The locking claws 41b form locking portions. Each locking claw 41b is elastically deformable as a whole and can be locked onto the locking wall 41a of the front member 10a. The rear frame portion 40b also has a polygonal rear gap 42b on its inner edge. The rear gap 42b forms a gap. The rear gap 42b is formed to penetrate from front to rear, thereby reducing the weight of the rear frame portion 40b. When the front member 10a and the rear member 10b are assembled, the front gap 42a and the rear gap 42b overlap to form a gap. For this reason, the front gap 42a and the rear gap 42b are shaped to overlap each other. In FIG. 10 and FIG. 1, only a part of the rear gap 42b is indicated by a reference numeral.
[0030] A rear plate 60 is formed on the rear surface of the rear member 10b, which is surrounded by the rear frame 40b. The rear plate 60 is plate-shaped and has curved surfaces that are curved in the left-right and up-down directions. The rear plate 60 is integrally formed with the rear frame 40b.
[0031] A partially enlarged view of the rear plate 60 is shown in the upper right of Figure 10. As shown in the figure, the rear plate 60 has a plurality of air vents 61 formed over its entire surface, penetrating the rear plate 60 in the front-to-rear direction. In the enlarged view, the air vents 61 are shown as white circles. Each air vent 61 has a minimum diameter portion on the rear side in the hole formation direction (front-to-rear direction), and is drum-shaped with a diameter that gradually increases forward and rearward from there. In addition, the rear opening edge of each air vent 61 is chamfered in an R-shape, and the front opening edge is not chamfered. The axes of each air vent 61 are parallel. Note that in the enlarged view, only some of the air vents 61 are marked with reference numerals.
[0032] As shown in the enlarged view, the ventilation holes 61 formed in the rear plate 60 are arranged as ventilation hole units 62, each consisting of a certain number of ventilation holes 61 grouped together in a hexagonal shape. These ventilation hole units 62 are arranged in a tortoiseshell pattern on the rear plate 60. In the honeycomb-shaped areas formed between the ventilation hole units 62, blind holes 63 having approximately the same diameter as the ventilation holes 61 are formed at the same pitch as the ventilation holes 61. In the enlarged view, the blind holes 63 are illustrated as colored circles. Therefore, the rear surface of the protector 10 and the rear member 10b constituting the protector 10 are uniformly spaced with the ventilation holes 61 and blind holes 63, creating a visually unified appearance. In front of the rear plate 60 where the blind holes 63 are formed, a rear reinforcing portion 80b is integrally formed with the rear plate 60 and serves as a reinforcing portion along the blind holes 63. Note that in the enlarged view, only some of the blind holes 63 are labeled.
[0033] 11 shows a front view of the rear member 10b. As shown in the figure, a rear reinforcement portion 80b made of a honeycomb-shaped wall is formed on the front surface of the rear member 10b. The rear reinforcement portion 80b is integrally formed of resin with the rear frame portion 40b and the rear plate portion 60. The rear of the rear reinforcement portion 80b is connected to the front surface of the rear plate portion 60, closing the rear of the rear reinforcement portion 80b, while the front of the rear reinforcement portion 80b is open. Because the air vents 61 are formed inside the hexagonal portion of the rear plate portion 60 in front of which the rear reinforcement portion 80b is not located, the hexagonal air vent unit 62 appears to have a tortoiseshell shape when viewed from behind the rear member 10b (upper right in FIG. 10).
[0034] As shown in FIG. 11 , the honeycomb-shaped walls constituting the rear reinforcement portion 80b extend in the same direction, and opposing honeycomb-shaped walls are parallel throughout the entire rear reinforcement portion 80b. The rear reinforcement portion 80b extends perpendicular to the front surface of the rear plate portion 60 near the center of the rear member 10b, but extends non-perpendicular to the front surface of the rear plate portion 60 at the lower left and right ends of the rear member 10b. The rear reinforcement portion 80b is formed with a plurality of positioning holes 81b that serve as positioning portions that open forward. These positioning holes 81b are formed opposite the positioning pins 81a of the front member 10a, allowing the positioning pins 81a to be inserted into them. The rear reinforcement portion 80b and the front reinforcement portion 80a are formed so that when the front member 10a and the rear member 10b are assembled, their honeycomb shapes coincide and overlap in a front or rear view, and their ends can abut against each other.
[0035] As shown in FIG. 11 , the polygonal rear gap 42b in the rear frame 40b is formed by removing weight from the inside of the honeycomb-shaped wall, extending the rear reinforcement 80b. The maximum diameter of each vent hole 61 is smaller than the length between opposing surfaces of the honeycomb-shaped wall that constitutes the rear reinforcement 80b, and is smaller than or equal to the thickness of the wall. The maximum diameter of each vent hole 61 is smaller than the length of the locking claw 41b (the length in the circumferential direction of the rear frame 40b) and the thickness of the rear plate 60. The maximum area of the opening of each vent hole 61 is smaller than the minimum area of the rear gap 42b. The thickness of the rear plate 60 is smaller than the height of the rear reinforcement 80b in the front-to-rear direction. The thickness of the honeycomb-shaped wall that constitutes the rear reinforcement 80b is larger than the maximum diameter of the vent hole 61.
[0036] Assembly of the front member 10a and the rear member 10b As shown in Fig. 5, the front frame portion 40a and the rear frame portion 40b are assembled so that the rear surface of the front member 10a faces the front surface of the rear member 10b and they overlap. Then, the positioning pins 81a of the front member 10a are inserted into the positioning holes 81b of the rear member 10b to be positioned, and the locking claws 41b formed on the rear frame portion 40b come into contact with the locking walls 41a formed on the front frame portion 40a and elastically deform. If the rear member 10b is pressed against the front member 10a in this state, the locking claws 41b will climb over the locking walls 41a and return to their original positions, where they will be locked by the locking walls 41a, resulting in the protector 10 shown in Figs. 1 to 4 in which the front member 10a and the rear member 10b are assembled.
[0037] Regarding the manufacturing method of the front member 10a (insert molding method of the mounting portion 30) The front member 10a is integrated with the mounting portion 30 by insert molding, and the molding method will be described below.
[0038] First, two mounting portions 30 are set in a fixed mold as inserts, and then a movable mold 101 is combined with a fixed mold 102, and resin that will become the protector body 20 is injection molded inside them. The front frame portion 40a, front plate portion 50, covering portion 70, and front reinforcing portion 80a are integrally formed with the injection-molded resin, and these become the protector body 20 of the front member 10a. Furthermore, each of the two inserted mounting portions 30 is partially covered by the covering portion 70.
[0039] Specifically, four fixing pins (not shown) are formed in the fixed mold 102, two for each mounting portion 30, to be inserted into the retaining holes 33 of the mounting portion 30. The mounting portion 30 is then set in the mold by engaging the fixing pins with the retaining holes 33. Because the base material 31 constituting the mounting portion 30 is thin, if resin is injected with the mounting portion 30 set in the mold, the base material 31 may be twisted due to the force and pressure of the injected resin. This can result in uneven thickness of the covering portion 70 formed while the mounting portion 30 is still twisted, potentially leaving exposed portions of the mounting portion 30 that should be covered by the covering portion 70. For this reason, support pins 101a and 102a are provided facing each other on the movable mold 101 and the fixed mold 102, respectively, to hold down the outer periphery of the mounting portion 30. When the movable mold 101 and the fixed mold 102 are set, the opposing support pins 101a and 102a clamp the outer periphery of the mounting portion 30 from both sides, thereby preventing twisting of the mounting portion 30 during resin injection.
[0040] FIG. 12 is a schematic cross-sectional view of the mold corresponding to line BB of the front member 10a shown in FIG. 6. As shown in the figure, the outer periphery of the inserted mounting portion 30 is clamped between the support pins 101a of the movable mold 101 and the support pins 102a of the fixed mold 102. In this way, even when resin is injected into the mold, the outer periphery of the mounting portion 30 is pressed in the thickness direction by the support pins 101a and 102a. This prevents the mounting portion 30 from being twisted by the force or pressure of the resin, thereby preventing the portion of the mounting portion 30 that should be covered by the covering portion 70 from being exposed. In this embodiment, 12 points on the outer periphery of each mounting portion 30 are clamped between the support pins 101a of the movable mold 101 and the support pins 102a of the fixed mold 102. The support pins 101a and 102a are cylindrical. Because no resin is molded at the positions of the support pins 101a and 102a, cylindrical support holes 73 are formed in the covering portion 70 of the front member 10a at 12 locations on the outer periphery of each mounting portion 30, exposing the mounting portion 30. When the mounting portions 30 are insert-molded, resin also enters the periphery of the elliptical holes 34, ensuring that the mounting portions 30 are insert-molded more firmly.
[0041] 13, each exposed portion 71 is formed by forming protrusions 101b, 102b on the movable mold 101 and the fixed mold 102 so that when the movable mold 101 and the fixed mold 102 are set, the protrusions 101b, 102b come into contact with the mounting portion 30 from both sides. In this way, resin is not molded into those portions, so that the exposed portion 71 can be formed. In addition, a recess (not shown) must be formed at the location where the male button 32 is located so that the male button 32 and the protrusions 101b, 102b do not interfere with each other.
[0042] How to install the protector body 20 FIG. 14 shows a method for attaching the protector body 20 to the garment 200. For ease of explanation, the protector body 20 to be attached will be collectively referred to as the protector 10. The protector 10 is used by being placed on the front of the wearer's chest. By attaching the protector 10 to the rear surface of the placket of the garment 200, the protector 10 is placed on the front of the wearer's chest via the garment 200. The garment 200 has female buttons 201 of snap buttons that engage with male buttons 32 arranged on the protector 10 corresponding to the position of the protector 10. Specifically, the placket of the garment 200 is divided into left and right plackets from the center front, and both plackets can be connected and disconnected by a zipper or the like. A sheet 202 with three female buttons 201 arranged vertically is sewn to the rear surface of each of the left and right plackets.
[0043] 14, first, the protector 10 is positioned near the chest, and the male buttons 32 provided on one of the two attachment portions 30 on the left and right are sequentially pressed into the female buttons 201 on the wearing body 200. In this way, the protector 10 is attached to the wearing body 200, albeit in a one-sided manner. When the male button 32 on the remaining attachment portion 30 is fitted into the female button 201 on the wearing body 200, the entire protector 10 is attached to the wearing body 200, and the protector 10 is positioned on the wearer's chest. Note that a wearing method in which the protector 10 is fixed to the wearing body 200 in a one-sided manner as shown in FIG. 14 before the wearer puts on the wearing body 200, and then the remaining male button 32 is fitted into the female button 201 on the wearing body 200 after putting on the wearing body, may also be used. When removing the protector 10 from the wearing body 200, the above-mentioned attachment procedure can be reversed.
[0044] According to the protector 10 and the manufacturing method of the protector 10 of the above embodiment, the following effects can be obtained. (1) In the above embodiment, the protector 10 includes a protector body 20 made of synthetic resin, and an attachment portion 30 that is partially exposed and covered from the protector body 20. The portion of the attachment portion 30 that is exposed from the protector body 20 has a male button 32 that enables the protector body 20 to be attached to a garment 200 worn by a wearer. This eliminates the need for a process of attaching a connecting belt to the protector 10, making it easier to manufacture the protector 10.
[0045] (2) The protector body 20 is configured by combining the front member 10a and the rear member 10b, and the male button 32 is exposed on the front surface of the front member 10a. This makes it easy to attach the garment 200 and the protector 10.
[0046] (3) The front member 10a and the rear member 10b are provided with locking walls 41a and locking claws 41b that can be locked to each other. The front member 10a and the rear member 10b are also provided with positioning pins 81a and positioning holes 81b that can be fitted together. This facilitates positioning and assembly when combining the front member 10a and the rear member 10b.
[0047] (4) The front member 10a and the rear member 10b are formed with a plurality of ventilation holes 51, 61 that communicate with the inside of the protector 10. Therefore, the ventilation holes 51, 61 allow wind to reach the chest of the wearer through the protector 10 while running.
[0048] (5) A front reinforcing portion 80a and a rear reinforcing portion 80b are integrally formed on the rear of the front member 10a and the front of the rear member 10b, respectively, thereby improving the protective performance of the front member 10a and the rear member 10b.
[0049] (6) The attachment part 30 has a plurality of (three in this embodiment) male buttons 32. This allows the attachment between the attachment part 30 and the wearing body 200 to be maintained even if some of the male buttons 32 come off.
[0050] (7) The mounting portion 30 is set in a mold, and resin is injected to cover the mounting portion 30 without injecting resin around the male button 32, thereby inserting the mounting portion 30. This allows the protector 10 to be manufactured in which the male button 32 is exposed and the mounting portion 30 is insert-molded.
[0051] (8) Inside the mold, the outer periphery of the inserted mounting portion 30 is clamped by the support pins 101a of the movable mold 101 and the support pins 102a of the fixed mold 102. Therefore, even when resin is injected into the mold, the outer periphery of the mounting portion 30 is pressed from both sides in the thickness direction. This prevents the base material 31 from being twisted by the force or pressure of the resin, and prevents the portion of the mounting portion 30 that should be covered by the covering portion 70 from being exposed without being covered.
[0052] (9) A gap is provided on the inner edge of the frame 40, and ventilation holes 51 and 61 are provided in the front plate 50 and the rear plate 60, and the front reinforcing portion 80a and the rear reinforcing portion 80b are made into honeycomb walls. This allows for weight reduction as desired by users, and makes the chest protector 10 more widespread.
[0053] The above embodiment may be modified as follows. Although three male buttons 32 are arranged on one mounting portion 30, the number is not limited to this. One, two, or four or more may be arranged.
[0054] Although the attachment means is the male button 32, it is not limited to this. The attachment means may be a female button, and the male button may be provided on the garment 200. Also, the attachment means may be a hook-and-loop fastener, so that the protector 10 can be attached to the garment 200.
[0055] Although the front reinforcing portion 80a and the rear reinforcing portion 80b are configured with honeycomb walls, they are not limited to this and may be other hollow structures. The size, shape, number, etc. of the ventilation holes 51, 61 formed in the front member 10a and the rear member 10b may be changed.
[0056] Although the front member 10a and the rear member 10b are locked by the locking wall 41a and the locking claw 41b, they may be fixed by adhesive, heat fusion, screws, rivets, etc. Also, the positioning fitting portion may be omitted.
[0057] Although the support pins 101a and 102a are cylindrical, the shape is not limited to this. For example, they may have a rectangular cross section, or may have an arcuate cross section when pressing the arcuate portions at the top and bottom ends of the mounting portion 30. This allows the mounting portion 30 to be pressed over a long range.
[0058] The maximum diameter of each vent hole 51 may be equal to or greater than the length between opposing surfaces of the honeycomb-shaped walls that make up the front reinforcement portion 80a, and may be greater than the thickness of the walls. The maximum diameter of each vent hole 51 may be equal to or greater than the length of the locking wall 41a (the length in the circumferential direction of the front frame portion 40a) and the thickness of the front plate portion 50. Furthermore, the maximum area of the opening of each vent hole 51 may be equal to or greater than the minimum area of the front gap portion 42a. The thickness of the front plate portion 50 may be equal to or greater than the height of the front reinforcement portion 80a in the front-to-rear direction. The thickness of the honeycomb-shaped walls that make up the front reinforcement portion 80a may be equal to or smaller than the maximum diameter of the vent hole 51.
[0059] The maximum diameter of each vent hole 61 may be equal to or greater than the length between opposing surfaces of the honeycomb-shaped walls that make up the rear reinforcement portion 80b, and may be greater than the thickness of the walls. The maximum diameter of each vent hole 61 may be equal to or greater than the length of the locking claws 41b (the circumferential length of the rear frame portion 40b) and the thickness of the rear plate portion 60. Furthermore, the maximum area of the opening of each vent hole 61 may be equal to or greater than the minimum area of the rear gap portion 42b. The thickness of the rear plate portion 60 may be equal to or greater than the fore-and-aft height of the rear reinforcement portion 80b. The thickness of the honeycomb-shaped walls that make up the rear reinforcement portion 80b may be equal to or smaller than the maximum diameter of the vent hole 61.
[0060] When the front member 10a and the rear member 10b are assembled, the honeycomb-shaped walls of the rear reinforcing portion 80b and the honeycomb-shaped walls of the front reinforcing portion 80a may be arranged so that the honeycomb shapes of the two walls do not coincide with each other when viewed from the front or rear, but are offset from each other.
[0061] When the front member 10a and the rear member 10b are assembled, the honeycomb-shaped walls of the front reinforcing portion 80a and the honeycomb-shaped walls of the rear reinforcing portion 80b may not come into contact with each other, and a gap may be formed. The rear opening periphery or the rear opening periphery of each of the ventilation holes 51, 61 may not be chamfered, or the rear opening periphery or the front opening periphery may be chamfered.
