Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to one of a pair of elastic
shoes, and more particularly to an elastic shoe having excellent
shock-absorbing effect to provide a comfortable sensation to a
user.
[0003] 2. Description of the Related Art
[0004] A conventional elastic shoe in accordance with the prior art
shown in FIGS. 9 and 10 comprises a shoe body 30 having a heel
portion 31, and an elastic mechanism 40 mounted on the heel portion
31 of the shoe body 30 to provide an elastic shock-absorbing effect
to the shoe body 30. The elastic mechanism 40 includes a plurality
of elastic posts 41 each having an inside formed with a through
hole 411. However, the elastic posts 41 cannot produce a restoring
force instantaneously when being subjected to a pressure, so that
the shock-absorbing effect of the elastic mechanism is limited
greatly, thereby easily causing an uncomfortable sensation to a
user.
[0005] The closest prior art reference of which the applicant is
aware was disclosed in the Taiwanese Patent Publication No.
521588.
SUMMARY OF THE INVENTION
[0006] In accordance with the present invention, there is provided
an elastic shoe, comprising a shoe body having a heel portion, and
an elastic mechanism mounted on the heel portion of the shoe body
to provide an elastic shock-absorbing effect to the shoe body. The
elastic mechanism includes a plurality of air cells, and a
plurality of plastic sleeves each mounted around a periphery of a
respective one of the air cells.
[0007] The primary objective of the present invention is to provide
an elastic shoe having excellent elasticity and shock-absorbing
effect to provide a comfortable sensation to a user.
[0008] Another objective of the present invention is to provide an
elastic shoe, wherein the relatively higher elastic plastic sleeves
are mounted around the air cells to produce a restoring force
instantaneously when being subjected to the pressure, so that the
elastic mechanism has an excellent resilience.
[0009] A further objective of the present invention is to provide
an elastic shoe, wherein the plastic sleeves having a relatively
higher elasticity are mounted around the air cells to produce a
restoring force instantaneously when being subjected to the
pressure to prevent the elastic mechanism from losing its elastic
force under the pressure, thereby enhancing the lifetime of the
elastic mechanism.
[0010] A further objective of the present invention is to provide
an elastic shoe, wherein when the applied pressure disappears, the
elastic mechanism can restore instantaneously by its excellent
resilience so as to provide an enhanced shock-absorbing effect to
the shoe body.
[0011] A further objective of the present invention is to provide
an elastic shoe, wherein when the air cells are subjected to a
pressure, the air cells are connected with each other so that the
applied pressure is distributed by the air cells smoothly and
evenly, thereby enhancing the shock-absorbing effect of the elastic
mechanism.
[0012] A further objective of the present invention is to provide
an elastic shoe, wherein the air cells and the plastic sleeves of
the elastic mechanism are made by a plastic injection molding
process, so that the elastic mechanism has a lighter weight,
thereby decreasing the weight of the shoe body.
[0013] Further benefits and advantages of the present invention
will become apparent after a careful reading of the detailed
description with appropriate reference to the accompanying
drawings.

DETAILED DESCRIPTION OF THE INVENTION
[0024] Referring to the drawings and initially to FIGS. 1-4, one of
a pair of elastic shoes in accordance with the preferred embodiment
of the present invention comprises a shoe body 10 having a heel
portion 11, and an elastic mechanism 20 mounted on the heel portion
11 of the shoe body 10 to provide an elastic shock-absorbing effect
to the shoe body 10.
[0025] The elastic mechanism 20 includes a plurality of air cells
21, and a plurality of plastic sleeves 22 each mounted around a
periphery of a respective one of the air cells 21. In the preferred
embodiment of the present invention, the elastic mechanism 20
includes four air cells 21 and four plastic sleeves 22.
[0026] The air cells 21 are arranged symmetrically and connected
with each other by a connecting pipe 23. The connecting pipe 23 has
a substantially X-shaped cross-sectional profile.
[0027] Each of the plastic sleeves 22 has a relatively higher
elasticity. Each of the plastic sleeves 22 is a hollow body and has
a substantially oblong cross-sectional profile.
[0028] As shown in FIG. 1, at least one of the air cells 21 has a
side provided with an inflating nozzle 24 to fill air into the air
cells 21 so as to adjust the air pressure contained in the air
cells 21.
[0029] As shown in FIGS. 1-5, when the air cells 21 are subjected
to a pressure, the air cells 21 are connected with each other so
that the applied pressure is distributed by the air cells 21
smoothly and evenly. In addition, the plastic sleeves 22 having a
relatively higher elasticity are mounted around the air cells 21 to
produce a restoring force instantaneously when being subjected to
the pressure, so that the elastic mechanism 20 has an excellent
resilience. Thus, when the applied pressure disappears, the elastic
mechanism 20 can restore instantaneously by its excellent
resilience so as to provide an enhanced shock-absorbing effect to
the shoe body 10. In addition, the air cells 21 and the plastic
sleeves 22 of the elastic mechanism 20 are made by a plastic
injection molding process, so that the elastic mechanism 20 has a
lighter weight, thereby decreasing the weight of the shoe body 10.
Further, the plastic sleeves 22 having a relatively higher
elasticity are mounted around the air cells 21 to produce a
restoring force instantaneously when being subjected to the
pressure to prevent the elastic mechanism 20 from losing its
elastic force under the pressure, thereby enhancing the lifetime of
the elastic mechanism 20.
[0030] Referring to FIG. 6, the elastic mechanism 20 includes five
air cells 21 and five plastic sleeves 22, wherein four air cells 21
are arranged symmetrically and one air cell 21 is located at a
central portion of the four air cells 21 and mounted on a central
portion of the connecting pipe 23.
[0031] Referring to FIG. 7, each of the plastic sleeves 22 has a
substantially semi-circular cross-sectional profile.
[0032] Referring to FIG. 8, each of the plastic sleeves 22 has a
substantially circular cross-sectional profile.
[0033] Accordingly, the relatively higher elastic plastic sleeves
22 are mounted around the air cells 21 to produce a restoring force
instantaneously when being subjected to the pressure, so that the
elastic mechanism 20 has an excellent resilience. In addition, the
plastic sleeves 22 having a relatively higher elasticity are
mounted around the air cells 21 to produce a restoring force
instantaneously when being subjected to the pressure to prevent the
elastic mechanism 20 from losing its elastic force under the
pressure, thereby enhancing the lifetime of the elastic mechanism
20. Further, when the applied pressure disappears, the elastic
mechanism 20 can restore instantaneously by its excellent
resilience so as to provide an enhanced shock-absorbing effect to
the shoe body 10. Further, when the air cells 21 are subjected to a
pressure, the air cells 21 are connected with each other so that
the applied pressure is distributed by the air cells 21 smoothly
and evenly, thereby enhancing the shock-absorbing effect of the
elastic mechanism 20. Further, the air cells 21 and the plastic
sleeves 22 of the elastic mechanism 20 are made by a plastic
injection molding process, so that the elastic mechanism 20 has a
lighter weight, thereby decreasing the weight of the shoe body
10.
[0034] Although the invention has been explained in relation to its
preferred embodiment(s) as mentioned above, it is to be understood
that many other possible modifications and variations can be made
without departing from the scope of the present invention. It is,
therefore, contemplated that the appended claim or claims will
cover such modifications and variations that fall within the true
scope of the invention.
