Description

SHOCK ABSORPTION SYSTEM FOR SHOES
TECHNICAL FIELD
This invention relates to a shock absorption device of a shoe, and
particularly, to a shock absorption system positioned in the heel of a
shoe. More particularly, this invention relates to a high technology
like a automobile shock absorption system for shoes that makes
incredible energy rebound and shock absorption for high pressure
impact, and maintain a good stability.
BACKGROUND ART
Generally, cushion inner soles have been provided for shoes and
boots which are formed of a compressible,elastic material such as
cellular plastic foams, foam rubber,etc. These inner soles have
provided only limited shock absorbency,resulting in a little or no
significant improvement in wearer's comfort.
Some prior art have provided inner soles with air cushions at
either the toe and heel areas,and some have provided cushions at both
areas with circulation between the air cushions. The cushions have
been provided with mechanisms to circulate air and ventilate the shoe
or boots during walking activities.
Examples of these are: U.K.Pat.Nos.2, 189,679 and 357,391: U.S. Pat. Nos.3, 180, 039, 2, 716, 293, 1 , 213, 941 and German Pat. No. 3, 144, 207.
In some shoe,boot, sneaker,etc, incorporates a foot-actuated pump in
the heel of the footwear which is connected to one or more air
bladders located in toe and other portions of the footwear. Examples
of these are U.S. Pat. No.4, 995, 173, and this inventor's Korean
Pat.No.60907, Korean Pat.Published Nos.94-7402 (Appln. No.91-20722),

,56' .
In operation the two plates 3,4 positioned in a heel portion 2 or
sole are acted upon at heel impact by the force of the wearer. The
force at heel strike will cause the upper plate 3 downward to the
lower plate 4 and the two links 8,9 are folded together. This will cause the guide rod 13 of the trailing member 11 inserted to the
opening 14 of the keeper member 12 .and the spring 15 is compressed (

compressed with the link rods 21, 22 .
Referred to FIG.8 and 9, the main plate 27 and coupling rods 29
,30 are pressed to downward with the buffer spring 16 by the force of
the sole portion.
In FIG.10 and FIG.11 , the two plates positioned in a heel portion
or sole are acted upon at heel impact by the force of the wearer. The
force at heel strike will cause the upper plate 41 downward to the
lower plate . This will cause the buffer spring 16 to be compressed
In FIG.12 and FIG.13 , the upper plate 49 is pressed to downward
and the roller 55 of the operating openings 53,53'are pressed with the pin shaft 57 and the trailing member 56 ,56' having the roller 55
