Description

  The present invention relates to a protective equipment for sports that is worn at a key point of a human body when playing sports such as soccer or volleyball.

  2. Description of the Related Art Conventionally, as this type of sports protector, for example, a so-called shin guard (sink pad) worn by a soccer player on a shin is known (see, for example, Patent Document 1). The shin guard includes a hard plate portion formed by molding a hard resin, and a shock absorbing portion made of foamed resin or a non-foaming elastic body provided on the back side of the hard plate portion. By providing a hard plate part, the guard when kicked with spiked shoes etc. is ensured, and by providing an impact absorbing part on the back side of the hard plate part, when it is kicked Impact is alleviated.

  Further, as sports equipment, for example, knee supporters called knee guards worn by volleyball players on knees and elbow supporters called elbow guards worn on elbows are known (for example, Patent Document 1). reference). These supporters are equipped with a stretchable cloth main body that covers the knees and elbows, and a shock absorber made of foamed resin or non-foamed elastic material attached to the main body. This reduces the impact on the knees and elbows.

  By the way, when the shock absorbing part is made of foamed resin, not only the sweat or rain water worn by the wearer during the competition adheres to the surface of the shock absorbing part but also accumulates in the foam cell of the shock absorbing part. The inside will also get dirty. In this case, bacteria grow on the surface and the inside of the shock absorbing portion using sweat or rainwater as a nutrient source, causing odors and being unsanitary. On the other hand, in order to keep the protective equipment for sports clean, it is conceivable to wash after use, but in this case, the washing water accumulates in the foamed cell, and the impact absorbing part is short in a short time. It is hard to dry. Accordingly, it is difficult to frequently clean the sports protective equipment and it is difficult to always use it in a clean state. In addition, although it is conceivable to wipe the sports protective equipment after use, it is not easy to wipe off the sweat and rainwater accumulated in the foamed cells, and it is difficult to keep them clean.

  On the other hand, if the shock absorbing part is made of non-foamed elastic material (non-foamed elastomer) or air bag (air bag), it can be cleaned quickly and easily just by wiping the shock absorbing part. It dries quickly and can be used immediately. Thus, the wearer can always use clean sports equipment.

  However, the non-foamed elastic body (non-foamed elastomer) described in Patent Document 1 has limited impact absorption and dispersion performance. In addition, the flat air bag described in Patent Document 2 is a single body, and since the plurality of air bags described in Patent Document 3 are formed independently of each other, the shock absorbing and dispersing performance is a single one. It will be limited.

  Accordingly, the present invention has been made to solve the above-described problems, and an object of the present invention is to provide a sports equipment with further improved shock absorption and dispersion performance.

  In order to achieve the above object, the present invention provides a sports protector including an impact absorbing portion, wherein the impact absorbing portion is composed of a plurality of air bags, and a communication portion for communicating between the air bags is provided. It is characterized by having.

  And the impact-absorbing part comprised from the said some air bag was equipped with the hard board part provided in a back surface, It is characterized by the above-mentioned.

  Alternatively, the supporter is provided with a mounting portion to which an impact absorbing portion composed of the plurality of air bags is mounted.

  In addition, an air bag that adjusts the internal pressure to atmospheric pressure through air without passing water is provided in an arbitrary air bag communicating through the communication portion.

  According to the present invention, since the shock absorbing portion is composed of a plurality of air bags, a good fit is obtained, and it is easy to keep clean without absorbing sweat and rain, and a certain air bag. Since the air compressed by the impact applied to the air appropriately flows out to the other air bag through the communication portion, the impact is efficiently absorbed and dispersed, so that the impact absorption and dispersion performance is improved.

  In addition, by providing a shock absorbing portion composed of a plurality of air bags with a hard plate portion provided on the back surface, a soccer player wears the shock absorbing portion composed of a plurality of air bags against the shin. This sports equipment can be used as a shin guard.

  Furthermore, by providing the supporter with a mounting portion to which a shock absorbing portion composed of a plurality of air bags is mounted, a volleyball player can use this sporting protective equipment as a knee or elbow supporter.

  In addition, by providing a breathable membrane that adjusts the internal pressure to atmospheric pressure through the air without passing water through any air bag that communicates with the communication section, the internal pressure of the air bag is always high without replenishing air. Since it is maintained at atmospheric pressure, it is maintenance-free and does not require performance adjustment. Furthermore, since air enters and exits through the gas permeable membrane, the air bag does not expand or collapse due to a change in temperature. Moreover, since the infiltration of water can be prevented by using the above air-permeable membrane, washing with water is also possible.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that the following description of the embodiment is merely an example, and is not intended to limit the present invention, its application, or its use.

(Embodiment 1)
FIG.1 and FIG.2 shows the shin guard 1 as a sports protector which concerns on Embodiment 1 of this invention. The shin guard 1 is used by a soccer player as a shin pad and has a plate shape that is curved so as to follow the shape of the shin as a whole. In addition, let the back surface of the shin guard 1 be a surface which contacts a shin, and let the surface be the surface on the opposite side.

  The shin guard 1 has a two-layer structure including a hard plate portion 10 constituting the front surface side shown in FIG. 1 and an impact absorbing portion 20 constituting the back surface side shown in FIG. The hard plate portion 10 is formed by injection molding a resin material such as polypropylene, nylon, polyurethane, polyester, polyethylene, polyvinyl chloride, or reactive curable resin. The hardness of the hard plate portion 10 is such a degree that the shin can be guarded when kicked by spike shoes during competition or when the athlete's feet collide with each other. The hard plate portion 10 has a shape that is long in the vertical direction of the shin as a whole and is curved as described above. As shown in FIG. 1, each of the upper, lower, left and right edges of the hard plate portion 10 is configured such that the center portion is curved inward, and the upper side is wider than the lower side. Yes. An approximately X-shaped convex portion 11 is formed diagonally on the surface side of the hard plate portion 10, and two substantially triangular vents 12, 12 are formed at the center of the approximately X-shaped convex portion 11. The upper, lower, left and right step portions 13 are formed with vent holes 14 along the shape of the step portion 13.

  On the other hand, the impact absorbing portion 20 is made of a resin having flexibility such as urethane elastomer, olefin elastomer, styrene elastomer, polyester elastomer, soft vinyl chloride, and a plurality of air bags on the back side of the hard plate portion 10. 21, 22 and 23 are provided. In the present embodiment, three large air bags 21 in the left and right up and down directions, three small air bags 22 in the up and down direction of the central portion, and two intermediate sizes on the left and right of the upper and lower ends, respectively. Air bags 23 are respectively formed. Between the two air bags 23 on the upper end side, an air injection hole 25 similar to a ball valve is formed which communicates with them via a communication portion 24 and can inject air with a ball hand pump. . These air bags 23, 23 communicate with the left and right air bags 21, 21 via communication portions 26, 26. Further, the left and right air bags 21 communicate with the central air bag 22 via the communication portion 27. Furthermore, the left and right lowermost air bladders 21 communicate with the lower left and right air bladders 23 via a communicating portion 28. That is, the air injection hole 25 and all the air bags 21, 22, and 23 communicate with each other, and the air bags 21, 22, and 23 communicate with each other.

  The shock absorbing portion 20 is formed integrally with the hard plate portion 10 so as to cover substantially the entire back surface of the hard plate portion 10. As shown in FIGS. 1 and 2, the shock absorbing portion 20 wraps around from the back surface side of the hard plate portion 10 to the front side through the entire peripheral edge portion and the peripheral edge portion of the central vent 12, It is formed so as to cover the peripheral edge of the vent. Therefore, the entire peripheral edge of the hard plate 10 and the peripheral edge of the vent 12 are in a state where the entire periphery is covered with the impact absorbing portion 20.

  When the shin guard 1 configured as described above is used, the impact absorbing portion 20 is directly applied to the shin, and a sock (not shown) is put on the shin, and the shin guard 1 is covered with the sock from the front side to the shin. Hold. At this time, the air pressure of the air bags 21, 22, and 23 can be adjusted to a desired fit with a ball hand bump. In addition, since the entire peripheral edge of the shin guard 1 and the peripheral edge of the vent 12 are made of a flexible resin that constitutes the shock absorbing part 20, it is in close contact with the socks and becomes slippery. Thereby, it can suppress that the shin guard 1 moves and a position shift during a competition.

  If the athlete sweats when the shin guard 1 is used, it is discharged through the gap between the air bags 21, 22 and 23. Further, hot air or humid air is also released to the outside from the vent holes 12 and 14. In addition, when another athlete's spiked shoe hits the shin guard 1, the shock absorbing part 20 composed of a plurality of air bags 21, 22, 23 communicates via the communication parts 24, 26, 27, 28. As a result, the impact is absorbed and dispersed efficiently and relaxed.

  FIG. 3 is a table showing shock absorption test results comparing the shin guard (product name: air shin guard) 1 of the above embodiment with other shin guards. In addition, the test method was performed with the weight of the fallen object: 0.25 kg and the drop height: 35 cm. As is apparent from the test results, the shin guard 1 of the present embodiment is described in Patent Document 1 (Japanese Patent Laid-Open No. 2008-214841) filed by the present applicant in a wide internal pressure range (atmospheric pressure to atmospheric pressure + 500 hpa). Compared with those using Sponge types 1 to 3 (manufactured by other companies), excellent shock absorption is shown.

  In addition, sweat and rain water worn by the athlete during use adheres to the shock absorber 20, but since the shock absorber 20 has no foamed cells, sweat and rain water are absorbed by the shock absorber 20. Absent. For this reason, it is possible to clean only by wiping the shock absorber 20. In addition, when the shock absorber 20 is cleaned, the cleaning water dries quickly because it is not absorbed into the shock absorber 20.

  As described above, according to the shin guard 1 according to the first embodiment, the shock absorber 20 is configured by the plurality of air bags 21, 22, and 23, and the communication that connects the air bags 21, 22, and 23 is performed. Since the parts 24, 26, 27, and 28 are provided, the impact absorption and dispersion performance is further improved. Further, since air injection holes 25 similar to the ball valves are provided in order to inject air into the air bags 21, 22, and 23, the air pressure thereof can be easily adjusted to a desired fit with a ball hand bump. Furthermore, it is possible to clean quickly and easily just by wiping the shock absorbing portion 20, and even when washed, it can be quickly dried to be ready for use. Thereby, the player can always use the clean shin guard 1.

  Further, since the shock absorbing portion 20 is led out to the surface side of the hard plate portion 10, the shock absorbing portion 20 and the hard plate portion 10 can be strongly coupled. Thereby, when a large force is applied to the impact absorbing portion 20 during sports or when it is used for a long time, the impact absorbing portion 20 can be prevented from being separated from the hard plate portion 10.

  Moreover, since the peripheral part of the hard board part 10 was coat | covered with the impact-absorbing part 20, the peripheral part of the hard board part 10 does not touch a player's skin directly and is damaged, and the safety | security at the time of mounting can also be improved.

  Moreover, since the vent holes 12 and 14 extending from the impact absorbing portion 20 to the hard plate portion 10 are formed, heat and sweat can be released in a state in which the athlete is wearing, and a feeling of wearing can be improved.

  In addition to the shin guard 1, the present invention can be applied to, for example, a baseball protector, a helmet, an arm guard, a lumbar protector, a spine protector, and a rugby headgear.

(Embodiment 2)
4, FIG. 5 and FIG. 6 show a knee supporter 30 as a sports equipment according to Embodiment 2 of the present invention. The knee supporter 30 is used by a player such as volleyball as a knee guard, and includes a cylindrical main body 31 and an impact absorbing portion 32 attached to the main body 31.

  The main body 31 is made of an elastic stretch cloth woven with elastic yarn, and is deformable so that the inner diameter is enlarged. On the inner surface of the main body 31, a thin cloth material is sewn into a bag shape that constitutes the accommodating portion 33 of the impact absorbing portion 32.

  As shown in FIGS. 5 and 6, the shock absorbing portion 32 has a configuration in which a plurality of substantially elliptical or substantially circular air bags 34 are radially connected, and includes a communication portion 35 that communicates between the air bags 34. ing. In addition, blank portions 36 are formed in which approximately one row in a radial pattern is eliminated so that some of the air bags 34 do not overlap when bent along the shape of the knee joint. Further, since the air bags 34 are arranged radially and a gap is formed between the air bags 34, air permeability is ensured and sweat and heat can be released.

  Also in the second embodiment, as in the first embodiment, a good fit can be obtained, and the air compressed by the impact applied to a certain air bag 34 is communicated with other air via the communication portion 35. Since the impact is efficiently absorbed and dispersed by appropriately flowing out into the bag 34, the impact absorbing and dispersing performance is further improved. Moreover, although the sweat which a player wore when using the said knee supporter 30 adheres to the impact-absorbing part 32, since there is no foam cell in the impact-absorbing part 32, it is not absorbed. In addition, when the shock absorbing part 32 is cleaned, the cleaning water is not absorbed into the shock absorbing part 32 and dries quickly.

  As described above, according to the knee supporter 30 according to the second embodiment, as in the first embodiment, the shock absorbing portion 32 is constituted by a plurality of air bags 34 and the air bags 34 are communicated with each other. Since the portion 35 is provided, the shock is efficiently absorbed and dispersed, so that the shock absorbing and dispersing performance is further improved. Further, it is possible to clean quickly and easily just by wiping the shock absorbing portion 32, and even when washed, it can be quickly dried to be ready for use. Thereby, the athlete can always use the clean knee supporter 30.

  In addition, since the shock absorbing portion 32 has a configuration in which the air bags 34 are connected radially, the gap between the air bags 34 functions as a vent hole, and sweat and heat can be released from the gap. Thereby, usability can be made favorable.

  Moreover, since it is easy to bend the shock absorption part 32 so that the shape of the joint part of a knee may be followed, the fitting feeling at the time of mounting | wearing can be improved and a much more favorable usability can be obtained.

  In the second embodiment, the case where the sport protector is the knee supporter 30 has been described. However, the present invention can also be applied to an elbow supporter having the same structure as the knee supporter 30.

(Embodiment 3)
7 to 11 are a top view, a front view, a right side view, a back view, and a cross-sectional view taken along line AA, showing another embodiment of the shock absorber for the supporter.

  The shock absorber 40 of the present embodiment has four air bags 41, 42, 43, 44 that are larger than the second embodiment and are curved so as to correspond to the knees, and are vertically connected via the communication part 45. ing. Further, a small air bag 47 for size adjustment is connected to both ends of the second largest air bag 42 from the top and the next (third from the top) air bag 43 through a communication portion 46. Yes. That is, when the size adjusting air bag 47 is connected as in the third embodiment, for example, the size becomes ML size, and when it is not connected, the size becomes S size without changing the size of the air bags 41 to 44 on the main body side. It is possible to easily cope with a plurality of sizes.

  In the second embodiment, no air injection hole is provided. However, in the third embodiment, the same air injection hole 48 as that in the first embodiment is provided at one end of the uppermost air bag 41. Is formed. That is, as in the first embodiment, the air injection hole 48 and all the air bags 41 to 44 and 47 communicate with each other, and the air bags 41 to 44 and 47 communicate with each other.

  Further, the connecting portion 49 between the air bags 41 to 44 is formed thin so as to be easily bent along the shape of the joint portion of the knee, and the groove portion 50 is formed at the left and right intermediate portions of the air bags 41 to 44. Has been. In addition, a plurality of vent holes 51 are formed in each of the air bags 41 to 44 almost equally.

  Also in the third embodiment, the above-described configuration provides substantially the same operational effects as the supporter of the second embodiment, and in order to inject air into the air bags 41 to 44 and 47 as in the first embodiment, Since the air injection hole 48 similar to the ball valve is provided, the air pressure can be easily adjusted to a desired fit with the ball hand bump.

(Embodiment 4)
12 and 13 show a shin guard 1 as a sports equipment according to Embodiment 4 of the present invention. The same reference numerals are used for the same or corresponding parts as those of Embodiment 1 of FIGS. Thus, duplicate descriptions are omitted. In the fourth embodiment, instead of the air injection hole provided in the shin guard 1 of the first embodiment, a gas permeable membrane having a function of adjusting the internal pressure to atmospheric pressure through air without passing water is provided. is there.

  More specifically, in the fourth embodiment, the air injection hole 25 provided between the two air bags 23 and 23 arranged on the upper end side of the back surface in the first embodiment is as shown in FIG. Not provided, the two air bags 23, 23 communicate with each other via the communication part 24. Other configurations on the back side are the same as those in the first embodiment.

  Then, in place of the air injection hole 25 of the first embodiment, in the fourth embodiment, as shown in FIG. 12, a circular protector is provided at the center upper portion of the substantially X-shaped convex portion 11 in the hard plate portion 10 on the front side. A ventilation film 62 (see FIG. 14) covered with 61 is provided. The protector 61 is formed with four vent holes 63 that are partitioned in a cross shape at the center. The protector 61 has a mounting recess 64 formed by introducing a flexible resin constituting the shock absorbing portion 20 from the back side of the hard plate portion 10 to the front side through a circular hole (not shown) formed in the hard plate portion 10. Attached to. As shown in FIG. 15, four vent holes 63 partitioned in a cross shape are formed in the central portion of the protector 61 configured in a disc shape as described above. As shown in FIG. 14B, a vent film 62 having a smaller diameter is attached to the back surface side of the protector 61 via a ring-shaped double-sided tape 65 having substantially the same diameter, and the vent film 62 is attached. The protector 61 is attached via a double-sided tape 65 to a mounting recess 64 in which a vent 66 communicating with the impact absorbing portion 20 on the back side of the hard plate portion 10 is formed. In the fourth embodiment, the air hole 66 to which the air permeable membrane 62 is attached communicates with the uppermost small air bag 22 at the center portion on the back surface side.

  Specifically, for example, a fluororesin porous film manufactured by Nitto Denko Corporation can be used as the gas permeable membrane 62. However, any material can be used as long as it allows only air to pass through without passing moisture or dust. . The protector 61 is a part that protects the gas permeable membrane 62. The protector 61 is made of resin, and PP (polypropylene) or the like can be used if it is a hard resin. But it can be used. The double-sided tape 65 fixes the gas permeable membrane 62 to the back surface of the protector 61, and fixes the protector 61 to the bottom surface of the mounting recess 64. By using the double-sided tape 65, the performance of the gas permeable membrane 62 is not impaired. The protector 61 and the gas permeable membrane 62 can be fixed. It should be noted that bonding or welding is possible if the ventilation portion of the ventilation film 62 is not adversely affected. The protector 61 and the double-sided tape 65 can be implemented without a protective film (polyester) because the air-permeable film 62 itself has a protective film (polyester). Further, in the fourth embodiment, the vent hole 66 to which the gas permeable membrane 62 is attached communicates with the uppermost small air bag 22 in the central portion on the back side, corresponding to the attachment portion on the front side. It can attach corresponding to the arbitrary air bags connected via a communicating part.

  The shin guard 1 provided with the above-described gas permeable membrane 62 is first blow-molded with a flexible resin (elastomer or the like) that constitutes the shock absorbing portion 20 by inserting the hard plate portion 10. Check for tightness. A vent hole 66 is formed in the exposed bottom of the mounting recess 64 described above for the molded product whose airtightness has been confirmed. Then, as shown in FIG. 14B, a ventilation film 62 is attached to the attachment recess 64 in which the ventilation hole 66 is formed on the back surface side of the protector 61 via a ring-shaped double-sided tape 65, and the ventilation hole 66 is attached thereto. Affixed to the bottom surface of the mounting recess 64 in which is formed.

  In the shin guard 1 provided with the gas permeable membrane 62 as described above, the internal pressure of the air bags 21, 22, and 23 of the shock absorbing unit 20 is always adjusted to atmospheric pressure by the action of the gas permeable membrane 62. According to the shock absorption test results of FIG. 3, the shin guard 1 having the above-described configuration exhibits excellent shock absorption in a wide internal pressure range (atmospheric pressure to atmospheric pressure + 500 hpa). Further, since the air permeable membrane 62 is composed of microscopic holes that allow air to pass but not water, air compressed by an impact applied to a certain air bag is almost released from the air permeable membrane 62 to the outside. Since it does not flow out and flows out appropriately to other air bags via the communication part, and the shock is absorbed and dispersed efficiently, the above-described excellent shock absorbing and dispersing performance is not impaired by the gas permeable membrane 62.

  Therefore, according to the shin guard 1 according to the fourth embodiment, substantially the same function and effect as those of the first embodiment can be obtained, and by providing the air permeable membrane 62 as described above, it is always possible to refill without air. Since the internal pressures of the air bags 21, 22, and 23 are maintained at atmospheric pressure, maintenance is free and performance adjustment is not required. In addition, since air enters and exits through the gas permeable membrane 62, the air bags 21, 22, and 23 are not inflated or crushed due to a change in temperature. That is, fluctuations in shock absorption performance due to environmental changes can be suppressed. Furthermore, by using a gas permeable membrane (fluororesin porous film) as described above, it is possible to prevent water from entering, so that it can be washed with water.

  In the fourth embodiment, the case where the gas permeable membrane 62 is applied to the shin guard of the first embodiment has been described. However, the present invention can be applied to the shock absorbers for supporters of the second and third embodiments. The same effect as in the fourth aspect can be expected.
