Definitions

  • the present disclosure relates to a shoe field, in particular, relates to a anti-sprain shock-absorbing balance air-cushion shoe.
  • a shoe is mainly constituted of a vamp and a sole.
  • the sole directly contacts with the ground, whether the shoe is comfortable or not mainly depends on the sole, because it is directly subjected to a friction from the ground, and simultaneously conveys a reacting stress from the ground to one’s feet. Therefore, sufficient shock-absorbing is necessary for the sole, since it can effectively protects one’s feet and reduces fatigue feeling, and further avoids any injury brought by exercise impact, and facilitates to realize exercise or competitive sports.
  • an air-cushion shoe was first invented.
  • Such shoe can act as a buffer to the impact between the foot and the ground, and can reduce the injury to one’s knees or ankles.
  • the sole will roll over for a certain angle, which will sprain one’s ankle, commonly known as sprain ankles.
  • the air-cushion shoe has better buffer effect, it is practical and efficient to provide an anti-sprain shock-absorbing balance air-cushion shoe.
  • the present invention provides an anti-sprain shock-absorbing balance air-cushion shoe, which has better shock-absorbing effect and can effectively avoid the occurrence of spraining one’s ankles during exercises.
  • the anti-sprain shock-absorbing balance air-cushion shoe provided by the embodiment of the present invention includes a shoe insert and a sole, the air-cushion shoe further includes two airbags communicating with each other, two airbag rooms are mounted in the upper surface of the sole, which are used to contain the two airbags separately.
  • the two airbag rooms are distributed in the sole along the left-to-right direction.
  • the combination of the shoe insert and the sole fixes the two airbags in the two corresponding airbag rooms separately, and the two airbag rooms are stretchable and compressible.
  • the two airbags intercommunicate with each other through a connecting tube, and the two airbags and the connecting tube which communicates the two airbags constitute together a row of shock-absorbing system.
  • the multiple rows of the shock-absorbing system are in turn distributed in the sole along the fore-to-aft direction, and both airbags in each row of the shock-absorbing system are arranged in the sole along the left-and-right direction.
  • the multiple rows of the shock-absorbing system are respectively arranged in the sole separate with one another.
  • a thickness of the heel part of the sole is larger than that of the forefoot part.
  • a thickness of the heel part of the sole is the same as that of the forefoot part.
  • a shallow groove is arranged in the bottom surface of the shoe insert, which is used to contain the top of the airbags separately.

  • the shoe insert is made of hard materials uneasy to deform, and the sole is made of soft material easy to deform.
  • the air-cushion shoe further includes a vamp which connects with the shoe insert.
  • the anti-sprain shock-absorbing balance air-cushion shoe provided by the embodiment of the present invention at least has the following advantages: first, the arrangement of the shock-absorbing system in the sole, which includes the airbags and the connecting tube which communicates the airbags, can buffer the impact from the ground to the foot, and performs better shock-absorbing effect. Second, when the airbag room on one side of the sole steps onto something like stones, the airbag room on the same side will be compressed and further the airbag in the same airbag room will be compressed correspondingly. Since the airbags are communicated by a connecting tube, gas in the compressed airbag will flow into another and drive the other airbag to inflate.
  • the inflation drives the other airbag room to stretch and exerts an influence to the ground, and therefore forms a torque opposite to the tendency of the rollover of the sole. Because of this, the rolling over of the sole is prevented and the sole is kept balance relatively, therefore the sprain is effectively avoided.

Please refer to FIGS.
  • the gas in the compressed airbag 21 flows to the other in order to make sure the air pressure in both airbags 21 are kept identical, which drives the airbag 21 on the other side to inflate, and the inflation drives its corresponding airbag room 121 to stretch, therefore a stress to the ground is produced by the inflation of the airbag room 121 and a torque opposite to the rolling tendency of the sole 12 is also produced, which will further prevent the sole 12 from rolling over and keep the sole 12 to be in a balance state, in this way, anti-sprain to the ankles is realized.

  • a connecting tube groove 112 is arranged in the bottom surface of the shoe insert 11, which is used to contain the connecting tube 22 communicating the two airbags 21. Since the bottom surface of the shoe insert 11 matches with the upper surface of the sole 12, the connecting tube groove 112 mounted in the bottom surface of the shoe insert 11 can contain the connecting tube 22, and there is no need to form groove in the sole 12, which can improve the strength of the sole 12.
  • a recess 120 is formed in the bottom surface of the sole 12 between the two airbag rooms 121, wherein the two airbag rooms 121 are separated by the recess 120. Because of this, the two airbag rooms 121 can be stretched and compressed separately.
  • the sole 12 and the shoe insert 11 can be prepared by such as an injection process separately.
  • the sole 12 can be prepared simultaneously with the airbag room 121, and the shoe insert 11 can be prepared simultaneously with the shallow groove 111 and the connecting tube groove 112.

  • a thickness of the heel part 12a of the sole 12 is larger than that of the forefoot part 12b. That is, this embodiment is suitable for those air-cushion shoes having heel parts.
  • the arrangement of the shock-absorbing systems 20 at the heel part 12a of the sole 12 can not only reduce the volume and weight of the air-cushion shoes, but also can lead to shock-absorbing and balance effect and avoid the occurrence of sprain during exercises, therefore solves the problem that the heel part bears most of the stress.

  • the airbags 21 can be rubber or other materials having good elastics.
  • the shoe insert 11 is made of hard material not easy to deform, and the sole 12 is made of soft material easy to deform. Since the sole 12 is soft enough, it can keep the balance of the shoe in slightly uneven grounds. However, when the sole 12 steps onto a larger object, the deformation of the sole 12 becomes larger, which drives the airbag 21 to be compressed. In this way, the rolling over of the sole 12 is restricted, and one avoids spraining his ankles. Meanwhile, the shoe insert 11 is made of hard materials, which can help maintain the horizontal stress to the foot.
