阅读说明：本技术 鞋类跟部弹簧装置 (Heel spring device for shoes ) 是由 蒂凡妮·A·比尔斯 约翰·T·丁莫夫 韦德·弗拉纳根 奥斯丁·奥兰多 乔治·A·赞索斯 于 2017-10-25 设计创作，主要内容包括：本申请涉及鞋类跟部弹簧装置。一种被构造成在鞋类物品的鞋跟部区包围足部接纳腔的一部分的装置,该控制条具有中央节段、从中央节段延伸的第一侧臂以及与第一侧臂间隔开并从中央节段延伸的第二侧臂。控制条可以包括一系列板条。基座支撑控制条并连接到第一侧臂和第二侧臂。控制条被偏置到无应力位置,此时中央节段距基座第一距离,并且在所施加的力的作用下弹性弯曲到加载位置,此时中央节段距基座比第一距离小的第二距离。该装置存储势能,在所施加的负载被移除时,该势能使控制条返回到未加载位置。(The present application relates to footwear heel spring devices. A device configured to enclose a portion of a foot-receiving chamber in a heel region of an article of footwear, the control strip having a central section, a first side arm extending from the central section, and a second side arm spaced apart from the first side arm and extending from the central section. The control bar may comprise a series of slats. The base supports the control bar and is connected to the first side arm and the second side arm. The control bar is biased to an unstressed position wherein the central segment is a first distance from the base and resiliently flexes under an applied force to a loaded position wherein the central segment is a second distance from the base less than the first distance. The device stores potential energy that returns the control bar to the unloaded position when the applied load is removed.)
