[0025] The toe protector is a protective device for the toes, used to prevent toe injuries or fractures, so as to reduce the impact of external impact on the toes and reduce the risk of fractures.

[0026] Based on this, the problem in the related art that when playing in water with slippers, the protection of the slippers is insufficient, which makes the ankles, metatarsophalangeal joints, sides of the feet and soles of the feet vulnerable to injuries can be improved.

[0027] See also Figure 1-Figure 16 A thumb proximal phalanx fracture protection device comprises: an outer protective shell 1, a metatarsophalangeal joint protector 2, a side protector 8, a fixing component 4 and an ankle protector 5, a protective component 10 is arranged inside the outer protective shell 1, an airbag component 13 is arranged at the top of the protective component 10, the airbag component 13 is located inside the outer protective shell 1, and when the protective component 10 is squeezed, the airbag component 13 is inflated, a plurality of reset components 14 are arranged inside the protective component 10, valve components 12 are arranged at the outer ends of the metatarsophalangeal joint protector 2 and the side protector 8, and a fixing component 4 is arranged at the outer ends of the metatarsophalangeal joint protector 2 and the side protector 8. A limiting component 6, a connecting belt 3 is arranged on the inner side of the two limiting components 6, the connecting belt 3 is made of elastic material, one end of the connecting belt 3 is fixedly connected to the outer end of the outer protective shell 1, the fixing component 4 includes a fixing ring 41, the outer end of the fixing ring 41 is fixedly connected to two mounting blocks 43, the ankle protector 5 includes a protective shell 51, the outer end of the protective shell 51 is fixedly connected to two mounting blocks 53, the other end of the connecting belt 3 is fixedly connected to the outer end of the protective shell 51, wherein: the metatarsophalangeal joint protector 2 and the side protector 8 are both slidably adjusted at the outer end of the connecting belt 3 through the limiting component 6.

[0028] The device in this scheme is mainly used for protecting toes. A protective component 10 is installed inside the outer protective shell 1, and an airbag component 13 is installed on the top of the protective component 10. Both the protective component 10 and the airbag component 13 are located inside the outer protective shell 1. The outer protective shell 1 is arranged in an arc shape and is hollow inside so that the toes can be inserted. The airbag component 13 is composed of two side airbags 131 and four intertoe airbags 132, and the airbag component 13 is connected to the inside of the air cushion 101. When the user steps on the ground, the gas inside the air cushion 101 will be squeezed into the airbag component 13. At this time, the five toes of the user are located between the side airbags 131 and the intertoe airbags 132, and will be squeezed and wrapped by the inflated airbag component 13, so that they can be tightly fixed on the foot and cooperate with the outer protective shell 1 to protect the toes.

[0029] On both sides of the outer shell 1 are fixed connecting belts 3, which are made of elastic material and can be retracted. The other end of the connecting belt 3 is fixedly connected to the outer end of the protective shell 2 51, and the metatarsophalangeal joint protectors 2 and the side protectors 8 are respectively arranged on the two connecting belts 3. The outer sides of the metatarsophalangeal joint protectors 2 and the side protectors 8 are provided with limiting components 6. The metatarsophalangeal joint protectors 2 and the side protectors 8 are installed on the connecting belts 3 through the limiting components 6. The metatarsophalangeal joint protectors 2 are mainly used for the protrusion of the metatarsophalangeal joint. The side protectors 8 are used to protect the sides of the foot. The positions of the metatarsophalangeal joint protectors 2 and the side protectors 8 on the connecting belt 3 can be adjusted through the limiting component 6 to adapt to different foot shapes, so that the metatarsophalangeal joint protectors 2 and the side protectors 8 can be located at appropriate positions to closely fit and protect the protruding parts of the metatarsophalangeal joints and the sides of the foot. Therefore, when playing in the water in slippers, since the protection effect of slippers on the toes is weak, the device in this scheme can improve the protection of the toes compared with traditional slippers, making the toe bones less likely to be injured.

[0030] Optionally, in some embodiments, see Fig.11 , Fig.12 and Fig.14 The airbag assembly 13 includes two side airbags 131 and four inter-toe airbags 132. The inside of the side airbags 131 and the inter-toe airbags 132 are both hollow. An external convex block 134 is provided at the top of the side airbag 131 near the side of the inter-toe airbag 132. The external convex block 134 is connected to the inside of the side airbag 131. Inner grooves 135 are provided on both sides of the inter-toe airbag 132. The inner grooves 135 fit the toes. The two side airbags 131 and the four inter-toe airbags 132 are connected through a connecting pipe 133.

[0031] The protective component 10 includes an air cushion 101, which is hollow inside. Six connecting plates 102 are installed on the top of the air cushion 101, and a pair of ventilation tubes 103 are installed on the top of the connecting plates 102. Two side air bags 131 and four intertoe air bags 132 are respectively connected to the six connecting plates 102. The side air bags 131 and the intertoe air bags 132 are connected to the inside of the air cushion 101 through the ventilation tubes 103. The internal gas of the air cushion 101 enters the side air bags 131 and the intertoe air bags 132 through the ventilation tubes 103. A plurality of magnetic blocks 11 are arranged inside the outer protective shell 1. A plurality of magnets compatible with the magnetic blocks 11 are installed at the bottom of the air cushion 101. The air cushion 101 can be detachably installed inside the outer protective shell 1.

[0032] The air cushion 101 in this solution is hollow inside and can be filled with air. Six connecting plates 102 of decreasing length are fixed on the top of the air cushion 101. The connecting plates 102 are mainly used to install the airbag assembly 13. The airbag assembly 13 is composed of two side airbags 131 and four inter-toe airbags 132. The lengths thereof are matched with the six connecting plates 102 in sequence to match the distribution of the toes. The two side airbags 131 are respectively the longest and the shortest. Two ventilation pipes 103 are arranged on the top of the connecting plate 102. When the side airbags 131 and the inter-toe airbags 132 are installed on the connecting plate 102 in sequence, The airbag assembly 13 can be connected to the inside of the air cushion 101 through the ventilation tube 103, and five gaps can be formed between the two side airbags 131 and the four intertoe airbags 132, so that five toes can be accommodated. An outer protrusion 134 is set at the top of the side airbag 131 close to the intertoe airbag 132, and inner grooves 135 are set on both sides of the bottom of the intertoe airbag 132. The gap formed between every two inner grooves 135 can accommodate the toes, and the outer protrusion 134 is used to fill the top gap between the side airbag 131 and the intertoe airbag 132 to protect the top of the toes.

[0033] When the user's five toes are inserted into the airbag assembly 13, the airbag assembly 13 is not filled with air at this time, but is in a deflated state, and the toes cannot be clamped and fixed. When the user steps down on the air cushion 101, the gas inside the air cushion 101 will flow into the side airbags 131 and the intertoe airbags 132 through the ventilation tubes 103 on the connecting plate 102. At this time, the side airbags 131 and the intertoe airbags 132 will expand to clamp the toes. At the same time, due to the soft characteristics of the airbags, the comfort of wearing can be improved, and the inflated airbag assembly 13 can also protect the toes. Therefore, when the user stands or walks, the inflated airbag assembly 13 can be used to fix the toes, thereby improving the convenience of use. A connecting tube 133 is also provided on the top of the side airbag 131 and the inter-toe airbag 132. The connecting tube 133 is mainly used to connect the side airbag 131 and the inter-toe airbag 132. A valve assembly 12 is installed at the end of the connecting tube 133 and the air cushion 101. The valve assembly 12 can control the connection between the inside and the outside of the airbag assembly 13 and the protective assembly 10. When it is necessary to deflate and store them, deflation can be carried out through the valve assembly 12.

[0034] At the same time, a plurality of magnetic blocks 11 are arranged inside the outer protective shell 1, and a matching magnet is installed at the bottom of the air cushion 101. Through the magnetic connection, the protective component 10 and the airbag component 13 can be removed separately, so that they can be used separately. Wearing the protective component 10 and the airbag component 13 and then wearing shoes, the toes can be protected by the inflated airbag component 13. For example, when working in a factory, when a heavy object hits the toes, the damage can be reduced by the cushioning of the airbag component 13.

[0035] Optionally, in some embodiments, see Fig.13 The reset assembly 14 includes two straight bars 141 and two reset bars 142. The reset bar 142 is arranged in a V shape, and the two ends of the reset bar 142 are fixedly connected to the two straight bars 141 respectively. The two straight bars 141 are fixedly installed at the top and bottom of the air cushion 101 respectively.

[0036] A plurality of reset components 14 are arranged inside the air cushion 101. The reset components 14 are composed of two straight bars 141 and two reset bars 142. The straight bars 141 and the reset bars 142 are connected to each other to form a complete closed frame. The straight bars 141 and the reset bars 142 are made of metal material. The reset bars 142 have a certain elasticity. The two straight bars 141 are respectively fixed to the bottom of the top inside the air cushion 101. When the user steps on the air cushion 101, the reset bars 142 will be squeezed and closed. When the air cushion 101 is not squeezed, the force of the reset bar 142 can slowly expand and reset the air cushion 101, and the gas inside the airbag assembly 13 can be re-absorbed into the air cushion 101. Therefore, when the user needs to take it off, the foot can be lifted up, and the reset assembly 14 can help the air cushion 101 to reset. It is worth mentioning that when the air cushion 101 is stepped on, the air cushion 101 cannot be completely deflated to prevent the reset bar 142 from being bent too much and unable to reset. Therefore, more gas needs to be blown into the air cushion 101 and the airbag assembly 13.

[0037] Optionally, in some embodiments, see Figure 8 and Fig.10 The metatarsophalangeal joint protector 2 includes a protective shell 21, a plurality of friction protrusions 22 are arranged on the inner side of the protective shell 21, a plurality of through holes 9 are opened on the outer ends of the protective shell 21 and the side protectors 8, the side protectors 8 are concavely arranged, the side protectors 8 are fitted with the sides of the foot, the protective shell 21 is arc-shaped, and the protective shell 21 is fitted with the convex part of the metatarsophalangeal joint.

[0038] A contact block 52 is provided on the inner side of the protective shell 51, and the protective shell 51 fits against the ankle. A plurality of friction blocks 42 equidistantly distributed in a circular shape are installed on the inner side of the fixed ring 41. Both the friction block 42 and the contact block 52 are made of silicone material, and the contact block 52 contacts the ankle.

[0039] The protective shell 1 21 mentioned above is in an arc-shaped cover state, and the protective shell 2 51 also presents a similar shape, so that it can just cover the protruding metatarsophalangeal joint and ankle. The protective shell 1 21 will fit on the outward protrusion of the metatarsophalangeal joint, and the protective shell 2 51 can just cover the ankle. The inner side of the protective shell 1 21 is provided with friction protrusions 22 made of sponge, which can increase its friction and prevent it from slipping. Through holes 9 are provided at the outer ends of the protective shell 1 21 and the side guards 8, which can achieve the effect of weight reduction. Abutment blocks 52 are provided in the internal recesses of the protective shell 2 51. When the protective shell 2 51 is fitted on the ankle, the abutment blocks 52 will abut against the ankle. The abutment blocks 52 are made of soft silicone. Because the ankles are under great pressure when people stand or walk, the comfort of the ankles can be improved by using the abutment blocks 52 made of silicone.

[0040] Two mounting blocks 53 are fixed at the outer end of the protective shell 51. The protective shell 51 is slidably mounted on the mounting belt 72 through the mounting blocks 53. By adjusting the position of the protective shell 51, the distance between the protective shell 51 and the airbag assembly 13 can be changed to adapt to soles of feet of different lengths. At the same time, the connecting belt 3 is made of elastic material. When the protective shell 51 is adjusted, the connecting belt 3 will be tightened. Through the elastic force of the connecting belt 3, the ankle protector 5 and the airbag assembly 13 can be tightened on the sole of the foot, so that the device can be firmly installed on the sole of the foot.

The other end of the mounting belt 72 is fixedly connected to the mounting block 43. The gasket 71 is made of rubber material.

[0048] The bottom pad assembly 7 in this solution is mainly used to protect the soles of the user's feet. The gasket 71 is made of rubber, one end of which is fixed to the bottom end of the outer protective shell 1, and the other end is fixed with a mounting belt 72. The mounting belt 72 passes through the mounting block 2 53 on the protective shell 2 51 and extends to the mounting block 1 43 to be fixedly connected thereto, so that the ankle guard 5 can be adjusted along the mounting belt 72, and the gasket 71 can isolate the sole of the foot from the ground to protect it.

[0049] The inner side of the fixing ring 41 is fixed with a friction block 42 made of silicone. When the fixing ring 41 is put on the calf, the friction block 42 can increase the friction force. The fixing ring 41 can be put on the calf to install the device in this solution.

[0050] The difference between this embodiment and the above embodiment is that Figure 17-22 The bottom pad assembly 7 is provided with a telescopic structure 8, and the bottom pad assembly 7 includes an upper bottom pad 73 and a lower bottom pad 74. The lower bottom pad 74 is provided with an adjusting cavity 741. The telescopic structure 8 includes a rotating disk 81 arranged in the adjusting cavity 741, and an arc groove 83 is provided on the rotating disk 81. A telescopic rod 84 is provided in the arc groove 83. The other end of the telescopic rod 84 is fixedly connected to the upper bottom pad 73. The telescopic rod 84 slides relative to the arc groove 83 through the rotation action of the rotating disk 81, so that the upper bottom pad 73 can move. The rotating disk 81 includes a rotating shaft 82, and a fixed seat 85 is rotatably connected to the rotating shaft 82. A through groove 86 is provided in the fixed seat 85. The telescopic rod 84 passes through the through groove 86 of the fixed seat 85 and is fixedly connected to the upper bottom pad 73.

[0051] The upper and lower sides of the telescopic rod 84 are slidably installed in the arc groove 83 through pin shafts.

[0052] A ratchet 87 is arranged on the outer fixed sleeve of the rotating shaft 82, and a limiting tooth 88 is arranged at the bottom of the fixed seat 85 to cooperate with the ratchet 87 to form a one-way rotation. A limiting shaft 89 is fixed at the bottom of the fixed seat 85, and a torsion spring 810 is fixed on the limiting shaft 89, and the other end of the torsion spring 810 is fixedly connected to the limiting tooth 88. A first sliding groove 811 is arranged at the bottom of the fixed seat 85, and a second sliding groove 742 is arranged on the lower base pad 74. The limiting shaft 89 is slidably arranged in the first sliding groove 811, and the limiting shaft 89 extends to the second sliding groove 742.

[0053] The telescopic rod 84 is made of elastic material. An elastic sleeve 731 covering the extension rod is connected between the upper base pad 73 and the lower base pad 74. The bottom of the rotating shaft 82 extends out of the lower base pad 74 and is connected to a rotating wheel 812.

[0054] By setting the retractable structure 8, the protective device can adapt to the foot size of different people. The rotating shaft 82 is driven to rotate by the rotating wheel 812, and the rotating shaft 82 drives the rotating disk 81 to rotate. Then, the telescopic rod 84 is driven to extend outward by the relative sliding of the arc groove 83 and the telescopic rod 84, which can drive the upper bottom pad 73 and the lower bottom pad 74 to separate, and expand the size of the protective device. In addition, the elastic sleeve 731 can protect the retractable structure 8, and the elastic coating material can also be filled in the elastic sleeve 731 to avoid affecting the normal walking action of the personnel. The ratchet 87 and the limiting tooth 88 are used to cooperate to form a one-way connection, which will not make the adjustment of the upper bottom pad 73 and the lower bottom pad 74 invalid. When it is not necessary to reset, the limiting shaft 89 is driven to slide in the first sliding groove 811 through the second sliding groove 742, and the limiting shaft 89 drives the limiting tooth 88 to disengage from the ratchet 87 through the torsion spring 810 to reset.

[0055] Working principle: When using the device, firstly, the fixing ring 41 needs to be passed through the sole of the foot to be set on the calf, and then the five toes are inserted into the outer protective shell 1. The airbag assembly 13 is made of two side airbags 131 and four inter-toe airbags 132. Five gaps can be formed between the two side airbags 131 and the four inter-toe airbags 132, so that the five toes can be accommodated. When the user steps down on the air cushion 101, the gas inside the air cushion 101 will flow into the side airbags 131 and the inter-toe airbags 132 through the ventilation pipe 103 on the connecting plate 102. At this time, the side airbags 131 and the inter-toe airbags 132 will expand and clamp the toes. Then, the protective shell 2 51 needs to be slid on the mounting belt 72 to change the distance between the protective shell 2 51 and the airbag assembly 13. When the protective shell 2 51 is adjusted, the connecting belt 3 will be tightened. Through the elastic force of the connecting belt 3, the ankle protector 5 and the airbag assembly 13 can be tightened on the sole of the foot, and the device can be firmly installed on the sole of the foot. Then, the metatarsophalangeal joint protector 2 and the side protector 8 are respectively adjusted to their positions on the connecting belt 3 through the control of the limit assembly 6, and the two buttons 64 are pinched to make the pressure rod 65 squeeze the inclined surface 2 610 on the movable block 68 through the inclined surface 1 67, so that the movable block 68 can drive the pressure plate 69 to move and disengage from squeezing the connecting belt 3, so that the metatarsophalangeal joint protector 2 or the side protector 8 can slide on the connecting belt 3, so that the protective shell 21 is attached to the outward protrusion of the metatarsophalangeal joint, and the side protector 8 is attached to the side of the foot. Therefore, compared with traditional slippers, the protection of the toes can be improved.
