In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the utility model. One skilled in the relevant art will recognize, however, that the inventive aspects may be practiced without one or more of the specific details, or with other methods, components, materials, etc. In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring aspects of the utility model.
The embodiments described in the following examples are soles with spring glue and shoes with the same, but the examples are only some of the embodiments of the utility model, and the protective scope of the utility model is not limited thereto. All other embodiments, which can be made by those skilled in the art without the inventive effort, are intended to be encompassed within the scope of the present utility model.
Referring to fig. 1 to 3 in combination, according to an embodiment of the present utility model, a sole is provided, including a sole body 1, a spring rubber 2 is disposed in a heel area of the sole body 1, the spring rubber 2 includes a rubber body 21 and a metal coil spring 22 wrapped in the rubber body 21, and in a use state of the sole body 1 (i.e. when a shoe with the sole is worn on a foot by a user), an elastic direction of the metal coil spring 22 is a vertical direction, and a material of the metal coil spring 22 may be specifically stainless steel.
According to the technical scheme, the spring rubber 2 is formed by arranging the metal spiral spring 22 in the rubber body 21 instead of an air cushion in the prior art, and an EVA midsole is not required to be arranged on the outsole, so that the sole has rebound performance, the defects that the EVA is easy to age and harden after worn and the air cushion is easy to crack in the prior art are overcome, the metal spiral spring 22 and the rubber body 21 both have rebound performance, the rebound performance of the spring rubber is not lost even if the rubber body 21 is damaged in an external scratch mode or the like, the rebound performance of the spring rubber is not lost, the shoes of the prior art are compared through experiments, the bounce of a wearer can be improved by about 2-3 cm (standing jump) and about 4-6 cm (running jump), and the bounce of the wearer can be improved by about 4-5 cm (standing jump) and about 7-10 cm (running jump) by using the sole of the utility model, and the bounce lifting effect is remarkable.
In some embodiments, the rubber body 21 is injection-molded around the outer periphery of the metal coil spring 22, so that the spring rubber 2 can be manufactured very conveniently, and in particular, it should be noted that the rubber body is completely wrapped around the inner and outer sides of the metal coil spring 22, that is, the outer periphery refers to the outer space of the metal coil spring 22, rather than the radial outer side of the single-finger spiral shape, with reference to the metal coil spring itself.
In some embodiments, the rubber body 21 is a cylinder, and the rubber body 21 of the cylinder has a smoother external profile, so that damage caused by the existence of edges and corners in the use process can be effectively prevented.
In some embodiments, the minimum width of the heel area of the outsole body 1 is L, the outer diameter of the rubber body 21 is D, L/3 is less than or equal to D is less than or equal to L/2, so that the outer side of the side standing wall of the outsole body 1 or the outer side possibly caused by too small distance from the side standing wall of the outsole body 1 can be prevented from being damaged by protruding after the compression expansion deformation of the spring rubber 2, that is, the spring rubber 2 can be hidden in the outsole body 1 no matter whether being stressed or not is ensured.
In a specific embodiment, in the use state of the outsole body 1, a horizontal suspension through groove 11 penetrating through the left and right sides of the outsole body 1 is formed in the heel area of the outsole body 1, a vertical through hole (not shown in the figure) is formed in a portion of the outsole body 1 above the horizontal suspension through groove 11, and the spring glue 2 is connected with a portion of the outsole body 1 below the horizontal suspension through groove 11 through the vertical through hole. The technical scheme provides a simple, feasible and reliable installation positioning structure of the spring rubber 2, the spring rubber 2 is assembled by inserting from top to bottom in the technical scheme, meanwhile, the reliable positioning of the spring rubber 2 is formed through the vertical through hole, and the service life of the sole is guaranteed.
The bonding between the contact portion of the spring glue 2 and the outsole body 1, for example, the bonding between the bottom end surface of the spring glue 2 and the portion of the outsole body 1 under the horizontal suspension groove 11, realizes the fixation of the bottom end of the spring glue 2, and the top end of the spring glue 2 is limited in the vertical through hole, and the hole wall of the vertical through hole is bonded with the contact portion of the spring glue 2, so as to realize the reliable positioning of the bottom end and the top end of the spring glue 2, and it can be understood that the portion of the spring glue 2 that is not contacted with the horizontal suspension groove 11 is free to deform after being stressed.
In some embodiments, the rubber body 21 is jelly silica gel, such as polyurethane jelly, which is a common commercial material, and reduces manufacturing cost.
In some embodiments, a rear wear-resistant sheet 31 is attached to the bottom surface of the heel region of the outsole body 1, and/or a front wear-resistant sheet 32 is attached to the bottom surface of the sole region of the outsole body 1 to enable improvement of wear-resistant and slip-resistant properties of the sole.
According to an embodiment of the utility model, there is also provided a shoe, preferably a sports shoe, having a sole as described above.
The above is only a preferred embodiment of the present utility model, and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model should be included in the protection scope of the present utility model.
