JP2012061046A - Easy-to-wear shoes - Google Patents

Abstract

PROBLEM TO BE SOLVED: To put on shoes more easily without stooping much when putting them on.SOLUTION: By enclosing a spring inside a heel part of a shoe, even if the shoe is put on while its heel part being trodden, the heel is restored by itself through a recovery action of the spring. In addition, by using an elastic material for side parts of the shoe as an auxiliary role, restoration of the heel part can be expected in furtherance of the solution.

Description

      The present invention relates to a shoe of the type in which a spring is provided on the heel portion of the shoe, and even if the heel is stepped on and pushed down directly, it immediately rises up directly by the force of the spring when it is worn and becomes the original heel It is.

      Conventionally, various inventions for providing easy-to-wear shoes have been made. However, as disclosed in Japanese Utility Model Publication No. Hei 6-15506, the inner part is formed of a flexible material even when stepping on the heel part. It is a shoe that can be easily returned to the original state, or a shoe that can be restored even if the heel portion is crushed by a reinforcing piece having flexible elasticity of Japanese Utility Model Publication No. 59-103602, or in utility model registration No. 3138353, If you remove the foot from the buttocks after using it with your feet, the shoes will automatically stand up from the sole, but it will certainly be excellent in terms of restoring the buttocks cleanly. . However, in either case, it means restoration when the shoes are taken off, and it is impossible at the stage where the feet are put. Japanese Patent Application Laid-Open No. 2010-104416 has found that it is very uncertain whether the heel portion will be distorted or the like and immediately restored when the foot is put into the shoe.

      It was sure that when the buttock was stepped on, it would be possible to make sure that the buttock could be restored immediately.

      The present invention has been studied by asking how to make sure that the buttock can be restored to its original position at the same time that the foot fits into the shoe even when the shoe is worn on the heel.

      And in order to give a certain restoring force to the buttocks, it came to the conclusion that the aggregate which becomes a spring is inevitable only with the simple material of the buttocks.

      For this purpose, it is necessary to have a stronger restoring force without impairing the appearance of the buttocks, and experiments were conducted using springs of various materials and forms.

      As a result of the experiment, when the spring of the form according to the present invention was used, even if the shoe was worn while stepping on the buttocks that was a problem, the heel was able to return immediately.

It is a perspective view of this invention. It is a description perspective view inside the collar part of this invention. It is an explanatory perspective view inside a collar part when a collar part of the present invention is pushed down. It is explanatory drawing of the spring of this invention.

      An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a finished product of the present invention, the appearance is not different from ordinary shoes, and FIG. 2 is an explanatory perspective view showing the internal structure of the heel part. In the manufacturing process, the spring (6) having the shape shown in FIG. 4 was processed into a U shape and attached.

      FIG. 3 is an explanatory perspective view of the spring (6) when the buttocks are pushed down directly when wearing shoes. In this case, if the material of the side surface part (4) is elastic enough to expand and contract, the restoring action of the spring (6) can be assisted.

      FIG. 4 is a perspective view of a spring, which is an important role of the present invention. When actually used in a shoe, it is processed into a U-shape, but is a shape in the previous stage.

      As shown in the figure, the whole spring to be used is gathered at both ends and the part is fixed, but the shape is a mountain shape designed at approximately equal intervals, comparing the top and bottom, The length is slightly longer at the top.

      Therefore, the spring (6) is processed into a U-shape, attached to the heel of the shoe, used as a shoe, and when the heel is pushed down with a foot, both ends of the spring are lowered as fulcrums (7). The upper spring spreads outward slightly, but the springs are less likely to overlap.

      Further, as a material used for the spring, not only a resin product that can be easily manufactured by placing it in a mold, but also a metal can be used.

Claims (2)

  U-shaped with an upper part (1) that wraps the instep, a lower part (2) that is made of a material that is relatively hard and does not lose shape, and a fulcrum (7) that is secured by bundling both ends. Side surface of the role connecting each of the collar part (5) containing several springs (6) bent into the upper part (1), the lower part (2), and the collar part (5) A shoe characterized by being formed by a portion (4). The shoe according to claim 1, comprising side parts (4) made of elastic material that expand and contract connected to both sides of the upper part (1) and both sides of the spring (6).
