The usage method is relatively rigid and not flexible enough. Summary of the Invention

[0005] The purpose of this invention is to provide an athletic shoe with an adjustable pressure airbag to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a sports shoe with an airbag, comprising:

[0007] vamp;

[0008] The sole is attached to the bottom of the upper.

[0009] An air bladder plate, embedded inside the sole, contains spaced-out front and rear air bladders arranged along the foot's axis, corresponding to the forefoot and heel areas respectively. Each air bladder contains a pressure regulating structure for manual adjustment of the internal air pressure. This structure includes a rotating block that twists and expands at the bottom of each air bladder. The upper end of the rotating block is connected to an elastically deformable regulating bladder via a tension band. The regulating bladder is fixedly connected to the inner top of its respective front or rear air bladder. An elastically compressible expansion strip is filled within the regulating bladder, forming an adjustable-volume bladder to regulate the air pressure within the corresponding front or rear air bladder.

[0010] As an alternative embodiment of the sports shoe with airbag described in this invention, the airbag plate is scaled and configured to fit the sole, and the airbag plate is fitted into the bottom of the sole by opening a groove, with the bottom surface flush with the edge of the sole.

[0011] As an alternative embodiment of the sports shoe with airbag described in this invention, the spiral block includes a circular plate-shaped screw head, a circular rod connected to the screw head, wherein the diameter of the circular rod is smaller than the diameter of the screw head, a threaded section is provided on the outer peripheral sidewall of the screw head, and a cross groove is opened on the bottom surface.

[0012] As an optional embodiment of the sports shoe with airbag described in this invention, wherein: a sealing ring and a threaded ring are fixedly embedded in the bottom of the front or rear airbag from top to bottom, the screw head is threadedly connected to the threaded ring, and an O-ring is fixedly connected to the outer wall of the round rod to seal the sliding passage through the sealing ring.

[0013] As an alternative embodiment of the sports shoe with airbag described in this invention, the adjustment bladder is configured as a hollow elastic rubber bladder, with a space between the bottom and the bottom of the front or rear bladder, and a tension band is arranged in the space between them.

[0014] As an alternative embodiment of the sports shoe with airbag described in this invention, the stretch band is configured as a non-elastic band, which is a cloth band or a PVC plastic band, and the stretch band is configured as a trapezoidal structure that is wider at the top and narrower at the bottom.

[0015] As an alternative embodiment of the sports shoe with airbag described in this invention, the expansion strip is set as a cotton strip.

[0016] As an alternative embodiment of the sports shoe with airbag described in this invention, wherein: a reinforcing layer is laid and connected on the outer surface of the airbag plate, and the reinforcing layer is a stainless steel wire mesh layer embedded in the outer wall of the airbag plate surface.

[0017] As an optional embodiment of the sports shoe with airbag described in this invention, the bottom surface of the airbag plate is glued with a bottom pad, and a movable sealing sticker is provided on the bottom pad corresponding to the position of each rotating block.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1

[0034] Please see Figure 1 , Figure 2 and Figure 8 The present invention provides a technical solution: a sports shoe with an airbag, comprising:

[0035] Shoe upper 1;

[0036] Sole 2 is attached to the bottom of upper 1;

[0037] An airbag plate 3 is embedded inside the sole 2. The airbag plate 3 is scaled to correspond to the sole 2. The bottom of the sole 2 is fitted with a groove to fit the airbag plate 3, and the bottom surface is flush with the edge of the sole 2 to form a complete sole surface for stable footing.

[0038] Inside the airbag plate 3, a front airbag 303 and a rear airbag 302 are arranged sequentially along the axial direction of the foot, corresponding to the foot plate and heel area respectively. Each airbag is equipped with a pressure regulating structure 304 for manually controlling the air pressure inside the airbag. The pressure regulating structure 304 includes a rotating block 3043 that twists and extends at the bottom of each airbag. The upper end of the rotating block 3043 is connected to an elastically deformable regulating airbag 3041 via a tension band 3049. The regulating airbag 3041 is fixedly connected to the inner top of the front airbag 303 or the rear airbag 302. An elastically compressible expansion strip 3042 is filled inside the regulating airbag 3041 to form an adjustable-volume airbag, thereby regulating the air pressure inside the front airbag 303 or the rear airbag 302.

[0039] As mentioned above, the bottom edge of the sole 2 should have a width of at least 10mm so that the airbag plate 3 can be stably wrapped at the edge after being glued in, ensuring the stability of the airbag plate 3 installation.

[0040] In this embodiment, the screw block 3043 includes a circular plate-shaped screw head 3044 and a round rod 3045 connected to the screw head 3044. The diameter of the round rod 3045 is smaller than the diameter of the screw head 3044. A threaded section is provided on the outer peripheral sidewall of the screw head 3044, and a cross groove is opened on the bottom surface.

[0041] To facilitate the torsional extension and retraction of the rotating block 3043: a sealing ring 3047 and a threaded ring 3046 are fixedly embedded in the bottom of the front bladder 303 or the rear bladder 302 from top to bottom. The screw head 3044 is threaded into the threaded ring 3046. An O-ring 3048 is fixedly connected to the outer wall of the round rod 3045 to seal the sliding passage through the sealing ring 3047.

[0042] In use, the user can use a Phillips screwdriver to align the screw with the Phillips head and turn it clockwise to move the round rod 3045 upwards, and counterclockwise to move it downwards. During the movement, the round rod 3045 contacts the smooth interior of the sealing ring 3047 through the O-ring 3048 to seal, preventing gas leakage from the bladder and enabling the rotating block 3043 to be manually operated for twisting and extending.

[0043] The regulating bladder 3041 is a hollow elastic rubber bladder with a space between its bottom and the bottom of the front bladder 303 or the rear bladder 302, and a tension band 3049 is arranged in the space between them.

[0044] Furthermore, in this embodiment, the tension band 3049 is a non-elastic band, made of cloth or PVC plastic, and has a trapezoidal structure that is wider at the top and narrower at the bottom. The wider upper part of the band is fixedly connected to the bottom surface of the adjusting bladder 3041, and the lower part is fixedly connected to the round rod 3045, so that after the rotating block 3043 extends or retracts, the tension band 3049 can stretch the adjusting bladder 3041 to perform elastic deformation.

[0045] Furthermore, the expansion strip 3042 is made of cotton, and the expansion strip 3042 inside the adjustment bladder 3041 is initially compressed and wrapped by the adjustment bladder 3041. When the counterclockwise rotating block 3043 moves downward, it pulls the adjustment bladder 3041 downward, causing the bladder to expand elastically. The internal expansion strip 3042 enlarges accordingly, filling the bladder and squeezing the gas in the bladder cavity outward, increasing the air pressure in the front bladder 303 or rear bladder 302. Conversely, rotating counterclockwise decreases the air pressure, thus adjusting the air pressure of the air bladder to meet the different wearing needs of the user.

[0046] It should be noted that the compression pressure of the expansion strip 3042 inside the regulating bladder 3041 is always greater than the air pressure in the bladder cavity. After being adjusted by the rotating block 3043, the expansion strip 3042 undergoes corresponding inflation changes after the regulating bladder 3041 is pulled.

[0047] As a further improvement of this embodiment 1, a reinforcing layer 301 is laid on the outer surface of the airbag plate 3. The reinforcing layer 301 is a stainless steel wire mesh layer, which is embedded in the outer wall of the airbag plate 3 to strengthen the protection of the airbag body when it is stepped on and compressed.

[0048] Example 2

[0049] To improve the effectiveness of use based on Example 1:

[0050] Please see again Figures 3-5 The bottom surface of the airbag plate 3 is glued to the bottom pad 4. The bottom pad 4 is provided with movable sealing stickers 401 corresponding to the positions of each rotating block 3043. The sealing stickers 401 are made of flexible rubber patches. The bottom pad 4 is provided with a groove 402 corresponding to the position of the sealing sticker 401. One end of the sealing sticker 401 is fixedly connected to the groove 402 to level the sole surface of the shoe and prevent mud from clogging the rotating block 3043.

[0051] It should be noted that the base pad 4 can be set as a rubber plate to protect the airbag plate 3 and to prevent wear and tear from ground contact. The sealing sticker 401 can be elastically squeezed into the filling cover groove 402 to cover and protect the head of the rotating block 3043. Alternatively, when adjusting the pressure, one end of the sealing sticker 401 can be pulled out to expose the rotating block 3043, allowing the user to adjust the air pressure of the front airbag 303 or the rear airbag 302 before reapplying the sealing sticker to cover it, thus meeting the walking and wearing needs of different users.

[0052] Example 3

[0053] To improve the effectiveness of use based on Example 2:

[0054] Please see again Figure 6 and Figure 7 The rotating block has an air inlet 306 through the screw head 3044 and the round rod 3045 along its axis. An air inlet 305 is provided at the nozzle on the outer end face of the screw head 3044 for inflation and deflation.

[0055] It should be noted that the 305 air core is used in conjunction with the air core needle, similar to inflating a basketball. This is existing technology, and the specific structure will not be described in detail. In addition to manual pressure adjustment by twisting the needle, it allows for inflation and deflation, providing additional pressure adjustment assistance and expanding the range of pressure regulation to meet the needs of some wearers.

[0056] In addition, the tension band 3049 is still fixedly connected to the end of the round rod 3045. The thickness of the tension band 3049 is set to be smaller than the inner diameter of the air hole 306, so that when the tension band 3049 is fixedly connected to the end of the round rod 3045, it does not block the air hole 306, thus meeting the working requirements of air pressure regulation.

[0057] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
