[0025] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0026] Reference Figure 1 The shoe with pneumatic ears comprises two ears 1, which are arranged on the shoe upper, near the outside of the shoe collar, and are symmetrically distributed. During walking, the two ears 1 can swing automatically.
[0027] Figure 2 The state after removing the upper and the upper layer of the sole is shown. Figure 3 The figure shows the state after the upper layer of the shoe upper is opened. Figures 1 to 3 The shoe comprises two first airbags 4, a second airbag 2 and a fixing member 7. The two first airbags 4 are correspondingly arranged inside the two ears 1, and the second airbag 2 is arranged inside the sole 6 and is connected to the two first airbags 4 through the air tube 5.
[0028] The first airbag 4 has two states: folded and unfolded. Figure 2 The first airbag 4 is in a bent state. When gas is filled into the first airbag 1, the pressure of the gas causes the first airbag 4 to change from the bent state to the unfolded state. The first airbag 4 has elasticity. When the gas inside the first airbag 4 is released, the elasticity causes the first airbag 4 to return to the bent state.
[0029] The first airbag 4 includes a head end 41 and a tail end 42, the head end 41 is connected to the ear 1, and the tail end 42 is connected to the trachea 5. The fixing member 7 is pressed on the trachea 5 and arranged close to the tail end 41 of the first airbag, and the fixing member 7 is connected to the upper 8 of the shoe.
[0030] The first airbag 4 can adopt the airbag of the existing pneumatic ear of this type of shoes. Exemplarily, the first airbag 4 includes an airbag body and an elastic sheet, the elastic sheet is arranged on the bent side of the airbag body or the side opposite to the bent side, and the original shape of the elastic sheet is the same as the shape of the first airbag in the bent state, so after the external force on the first airbag is eliminated, the elastic sheet can drive the airbag body to return to the bent state.
[0031] When wearing the shoe and walking, the second airbag 2 is squeezed when the foot lands, and the second airbag 2 inflates the first airbag 4 through the trachea 5. The gas pressure causes the first airbag 4 to overcome the elastic force and change from a bent state to an unfolded state. During this state change, the first airbag 4 drives the ear 1 to swing. When the foot is lifted, the gas in the first airbag 4 flows back to the second airbag 2, the gas pressure on the first airbag 4 is eliminated, and the first airbag 4 is reset under the action of its own elastic force, changing from an unfolded state to a bent state. During this state change, the first airbag 4 drives the ear 1 to swing in the opposite direction, and this is repeated, thereby achieving automatic and continuous swinging of the two ears 1 on the shoe when walking.
[0032] Since the head end 41 of the first airbag 4 is connected to the ear 1 and the tail end 42 of the first airbag 4 is connected to the trachea 5, the fixing part 7 is pressed on the trachea 5 and arranged close to the tail end 42 of the first airbag 4, and connected to the upper 8, so that the head end 41 and the tail end 42 of the first airbag 4 are both fixed to the shoe, and the first airbag 4 will not move or shake relative to the ear 1, so the ear 1 can swing stably under the drive of the first airbag 4.
[0033] In this embodiment, the fixing member 7 is two pressing belts, which are arranged corresponding to the two ears 1 of the shoe and are sewn onto the shoe upper 8 .
[0034] Figure 4 Another embodiment of the fixing member is shown. Figure 4 In another embodiment, the fixing member 7 is a pressing belt, which includes two pressing parts 72 and a bridge part 71 bridging the two pressing parts 72. The two pressing parts 72 are provided corresponding to the two ears 1 of the shoe, and the pressing belt is sewn on the upper 8. Compared with the embodiment using two pressing belts, the embodiment using one pressing belt can fix the airbags of the two ears by sewing once, which is more convenient to manufacture.
[0035] As a third embodiment, the ear 1 includes an ear body, and the ear body is formed with an extension portion extending along the upper toward the toe at the ear root, and the extension portion is crimped onto the trachea 5 and sutured to the upper 8, thereby fixing the tail end 42 of the first airbag 4. Compared with the above-mentioned embodiment of the pressure belt, the third embodiment uses the ear 1 fabric to form the fixing member 7, thereby saving the process of cutting the pressure belt.
[0036] In the above embodiments, the fixing member is connected to the shoe upper by sewing.
[0037] Figure 5 FIG. 8 shows an embodiment of the suture of the fixing member 7 and the upper 8. Figure 5As shown, the air tube 5 is on the shoe upper 8, the fixing member 7 is pressed on the air tube 5, the edge of the fixing member 7 is sewed to the shoe upper 8, and the sewed line 9 is substantially perpendicular to the air tube 5. The channel enclosed between the fixing member 7 and the shoe upper 8 is adapted to the outer diameter of the air tube 5, so that the air tube 5 is fixed on the shoe upper, so that the tail end 42 of the first air bag is fixed on the shoe upper and will not move or shake.
[0038] Figure 6 Another embodiment of the suturing of the fixing member 7 and the upper 8 is shown. Figure 6 As shown, compared Figure 5 Example, Figure 6 In the embodiment, the fixing member 7 is provided with sutures 9 on the left and right sides corresponding to the trachea 5 in the same extending direction as the trachea 5, that is, Figure 6 The dotted line extending in the horizontal direction in the middle, the suture line has a limiting effect on the trachea 5, so it is called a limiting line. Since the limiting effect is exerted on the trachea within the length and width of the limiting line, the end of the trachea 5 connected to the first air bag 4 can be better fixed on the upper 8, thereby better fixing the tail end 42 of the first air bag 4.
[0039] Optionally, the fixing piece may also be combined with the upper via a connection structure such as Velcro or snap fasteners.
[0040] In some embodiments, the head end 41 of the first airbag 4 is sutured to the ear 1 .
[0041] Optionally, the head end 41 of the first airbag 4 may also be connected to the ear 1 via a connection structure such as Velcro or snap fasteners.
[0042] The second airbag 2 is connected to an air return valve 3, which is a one-way valve that conducts one-way from the environment to the second airbag 2. When the air pressure in the second airbag 2 is lower than the ambient air pressure, ambient air can flow into the second airbag 2 through the air return valve 3, thereby ensuring that the second airbag 2 has sufficient air to drive the ear 1 to swing.
[0043] In one embodiment, the sole 6 includes two layers, an upper layer and an lower layer, and an airbag accommodating groove, an air tube accommodating groove and a valve accommodating groove are provided between the two layers. The second airbag 2, the air tube 5 and the return air valve 3 are correspondingly arranged in the airbag accommodating groove, the air tube accommodating groove and the valve accommodating groove.
[0044] In one embodiment, the second airbag 2 is arranged corresponding to the heel of the foot, and the air tube 5 extends to the toes in the sole 6, then bends into the upper 8, and extends to the ear 1 in the upper 8.
[0045] In one embodiment, a support strap made of non-elastic material is further provided at the collar of the shoe. Since the support strap is made of non-elastic material, the collar will not be expanded when the foot is pressed outward, so the foot will not move forward and backward relative to the shoe during walking, which can avoid the problem of the airway at the front end of the shoe squeezing the toes after the collar is expanded. To avoid causing discomfort to the foot, the support strap is preferably a fabric strap, which is sewn to the inner side of the shoe collar, and the fabric is, for example, non-elastic fabric.
[0046] It should be pointed out that, unless otherwise specified, the above-mentioned "first", "second" and other similar terms are used to distinguish different devices with the same name and cannot be interpreted as having meanings of order, priority, importance, etc.
[0047] The above-mentioned specific embodiments are used to describe the present invention in detail. These detailed descriptions are only limited to helping those skilled in the art understand the content of the present invention and cannot be understood as limiting the protection scope of the present invention. Various modifications, equivalent transformations, etc. made by those skilled in the art to the above-mentioned scheme under the conception of the present invention should be included in the protection scope of the present invention.
