Definitions

  • the present inventions relate to an inner sole of a shoe.
  • inner soles for shows which are to be laid on an insole of the shoe in order to absorb shock applied to the sole of a foot of a walker or wearer of the inner sole (see e.g. Japanese Laid-open Patent Publication No. 197504/2000).
  • the inner sole of JP Publication No. 197504/2000 is made of a flexible material and has a space in which liquid is flowably contained in a sealed manner so as to have a massaging effect in addition to the shock absorbing effect.
  • An aspect of at least one of the inventions disclosed herein includes the realization that by controlling the flow rate of a liquid between multiple chambers of an insole, the shock absorbing effect and massaging effect to the sole of a foot of a walker can be improved.
  • an inner sole to be laid on an insole of a shoe can have a body made of flexible material and formed therein with a liquid containing space for sealingly and flowably containing liquid therein.
  • the inner sole can comprise dam portions dividing the liquid containing space into a toe region, a heel region and a middle region therebetween.
  • the inner sole can comprise orifices for communicating the liquid between mutually adjacent regions at a predetermined flowing rate.
  • an inner sole for a shoe can comprise a body made of flexible material.
  • the body can include a liquid containing space and a liquid disposed in the liquid containing space.
  • the inner sole can further comprise a toe dam portion and a heel dam portion dividing the liquid containing space into at least a toe region, a heel region and a middle region therebetween.
  • the toe dam portion and the heel dam portion can be configured to allow the liquid in the liquid containing space to flow through the toe and heel dam portions at predetermined flow rates.
  • an inner sole for a shoe can comprise a body made of flexible material.
  • the body can include a liquid containing space and a liquid disposed in the liquid containing space.
  • the inner sole can further comprise a toe dam portion and a heel dam portion dividing the liquid containing space into at least a toe region, a heel region and a middle region therebetween.
  • the toe dam portion and the heel dam can include means for controlling flow rate of the liquid through the toe and heel dam portions.
  • FIG. 1 is a plan view of the inner sole according to an embodiment
  • FIG. 2 is a cross-sectional view taken along a line II-II of FIG. 1 ;
  • FIG. 3 is a schematic view showing a method of experiment that can be used to understand effects obtained by an inner sole, such as the inner sole of FIGS. 1 and 2 ;
  • FIG. 4 is a schematic view of an inner sole that can be used as a comparative example to the inner sole of FIGS. 1 and 2 , described below as “Comparative Example 1”, using the method of FIG. 3 ;
  • FIG. 5 is a graph showing a pressure distribution obtained in the method of FIG. 3 , using an inner sole in accordance with the embodiment of FIGS. 1 and 2 ;
  • FIG. 6 is a graph showing a pressure distribution obtained in the method of FIG. 3 , using the Comparative Example 1 inner sole.
  • FIG. 7 is a graph showing a pressure distribution obtained in the method of FIG. 3 , using another comparative example, described below as “Comparative Example 2”.
  • an embodiment of an inner sole to be laid on an insole can comprise a body of the inner sole including an upper inner sole member 1 a and a lower inner sole member 1 b which can be adhered and sealed in a liquid tight manner for containing therein liquid such as water W, or any other liquid.
  • the inner sole can also include dam portions 2 and 3 , a second dam portion 4 , and a third dam portion 5 .
  • Each of the upper and lower inner sole members 1 a and 1 b can have an overall shape or configuration substantially same as that of an insole of a shoe on which they are laid.
  • the sole members can be made of two flexible members (e.g. elastic synthetic resin etc.).
  • the upper and lower inner sole members 1 a and 1 b can be, for example, heat sealed to each other at their edges so that a liquid containing space for containing liquid such as water W is formed between them.
  • Material for forming the upper and lower inner sole members 1 a and 1 b can be any one selected from various plastics or synthetic resins so long as it has a durability and flexibility suitable for the inner sole.
  • the dam portions 2 and 3 can be formed by heat welding the upper and lower inner sole members 1 a and 1 b . However, any other technique can also be sued.
  • the arrangement of the various dam portions can be configured to divide the liquid containing space into a toe region A, a heel region C and a middle region B therebetween. However, other regions can also be used.
  • the dam portions 2 and 3 can be arranged so that they form the toe region A corresponding to a toe region of a shoe on which insole the inner sole is laid, the heel region B corresponding to a heel region of the shoe, and the middle region B between the toe and heel regions of the shoe.
  • these regions A, B, C can also be further subdivided, as described below in greater detail.
  • Opposite ends of the upper and lower inner sole members 1 a and 1 b can be arranged so that they are separated a predetermined distance from the heat sealed edges of the upper and lower inner sole members 1 a and 1 b . As such, these separated portions can form orifices, such as orifices R 1 and R 2 as shown in FIG. 1 .
  • each orifices R 1 and R 2 can be set so that the liquid contained in the inner sole can flow at a predetermined flow rate between two adjacent regions divided by the dam portions 2 and 3 . Accordingly, when a load is applied to the heel region C, liquid contained in the heal region C can flow into the middle region B and then into the toe region A through the orifices R 2 and R 1 respectively. Similarly, when a load is applied to the toe region A, liquid contained in the toe region A can flow into the middle region B and then into the heel region C through the orifices R 1 and R 2 respectively.
  • Provision of the toe region A, middle region B and heel region C as well as the orifices R 1 and R 2 allows the liquid (e.g. water) to flow from the heel region C into the middle region B or from the toe region A into the middle region B responding to a timing of walk during walking of a walker or wearer of the inner sole and thus makes it possible to improve the massaging effect to the sole of a foot of a walker.
  • liquid e.g. water
  • Each of the dam portions 2 and 3 can optionally be formed as having an arc configuration, being convex toward the toe region A from the heel region C.
  • Such a configuration can be used to make the flow rate when the heel of a shoe equipped with the inner sole contacts a ground (i.e. when the liquid flows from the heel region C to the toe region A through the middle region B) slower than that when the toe of a shoe equipped with the inner sole contacts a ground (i.e. when the liquid flows from the toe region A to the heel region C through the middle region B).
  • a ground i.e. when the liquid flows from the heel region C to the toe region A through the middle region B
  • other configurations can also be used to achieve this effect.
  • a second dam portion 4 can be added in the toe region A by any technique, including heat welding the upper and lower inner sole members 1 a and 1 b to divide the toe region A into fore and aft two portions i.e. a first toe region Aa and a second toe region Ab.
  • the second dam portion 4 can extend over full width of the toe region A to limit liquid flow between the first and second toe regions Aa and Ab.
  • an orifice R 3 can be provided for allowing partial liquid flow therebetween.
  • the provision of the orifice R 3 enables to further finely control the liquid flow in the toe region A especially in rearward kicking of the shoe against a ground. For example, when a load is applied to the first toe region Aa from the sole of a foot of a walker during his walking, since the liquid within the first toe region Aa flows not only into the middle region B but into the second toe region Ab, the elasticity caused by the liquid can be better controlled.
  • the middle portion B can be formed with a spread portion Ba at a position corresponding to a shank portion of a shoe on which the inner sole is laid. Since the inner sole shown in FIG. 1 is for a right hand foot, the spread portion Ba is shown arranged at a left hand side of the inner sole. However, it is of course that the spread portion Ba is arranged at a right hand side of a inner sole for a left foot configuration. Similarly to the other regions, the spread portion Ba can also form a part of the liquid containing space.
  • a third dam portion 5 can be arranged between the spread portion Ba and the middle region B by any technique, including heat welding the upper and lower inner sole members 1 a and 1 b similarly to the dam portions 2 and 3 and the second dam portion 4 and orifices R 4 are formed between the spread portion Ba and the middle region B to control the liquid flow.
  • the spread portion Ba can also effectively apply massaging effect to the sole of a foot of a walker.
  • the spread portion Ba has a generally vertically bulged configuration along a configuration of the arch of a foot of a walker.
  • the third dam portion 5 can be formed as having an arc configuration, convex toward the middle region B from the spread portion Ba. This shape can make the flow rate from the spread portion Ba to the middle region B slower than that from the middle region B to the spread portion Ba. This makes it possible to improve the massaging effect to the arch of a foot of a walker. However, other configurations can also be used to provide this effect.
  • a sheet member “a” of hard synthetic resin is laid on a floor.
  • an inner sole “b” submitted for the experiment (omitted in case of experiment as to bare foot), a thin leather member “c” and a sensor sheet “d” are laid on successively.
  • a sample “Embodiment” is an inner sole shown in FIG. 1
  • a sample “Comparative Example 1” is an inner sole shown in FIG. 4
  • a sample “Comparative Example 2” is a condition in which no inner sole is used and only the sensor sheet “d” is laid on the thin leather member “c”.
  • the “Comparative Example 1” is formed so that it comprises a space S for containing water W therein and a plurality of linear projections Sa which do not partition the space S (accordingly, the space S is kept in a communicated condition).
  • the experiment was carried out as to the samples identified as “Embodiment”, “Comparative Example 1” and “Comparative Example 2” by measuring the pressure distribution with laying feet on the sensor sheet “d”. Results of the experiment are shown in FIGS. 5, 6 and 7 as to the samples “Embodiment”, “Comparative Example 1” and “Comparative Example 2” respectively.
  • the sample “Embodiment” can distribute the pressure applied to the sole of a foot more evenly than those of the samples “Comparative Example 1” and “Comparative Example 2”. This more even pressure distribution is found even in the arch of a foot. Accordingly this proves that the embodiments of the inner sole described above can have excellent shock absorbing effect as well as massaging effect as compared with the “Comparative Example 1” and “comparative Example 2”.
  • any liquid other than water e.g. oil having a predetermined viscosity may be used.
  • water reduces the manufacturing cost of the inner sole.
  • the second toe region Ab may be flattened by heat welding its whole region and the third dam portion 5 may be omitted.
  • the present inventions can also be applied to other inner soles having different configurations or additional functions as far as it has dam portions for dividing the inner sole into the toe region, middle region and heel region as well as orifices for controlling the flow rate passing therethrough.
