Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a shoe sole, and more
particularly to a shoe sole having a resilient cushioning device
for the heel portion thereof.
[0003] 2. Description of the Prior Art
[0004] Typical shoe soles may comprise one or more bladders or air
chambers formed in the shoe soles, to increase the resilience of
the shoe soles, and to resiliently support the heel portions of the
users.
[0005] However, the bladders or the air chambers formed in the shoe
soles may not be used to effectively cushion the heel portions of
the users.
[0006] The present invention has arisen to mitigate and/or obviate
the afore-described disadvantages of the conventional shoe
soles.
SUMMARY OF THE INVENTION
[0007] The primary objective of the present invention is to provide
a shoe sole including a resilient cushioning device for attaching
to the heel portion thereof to effectively cushion the heel
portions of the users, and thus to comfortably support the heel
portions of the users.
[0008] In accordance with one aspect of the invention, there is
provided a shoe sole comprising a heel portion and a front portion,
and a resilient cushioning device engaged in the heel portion of
the shoe sole for cushioning heel portions of users. The resilient
cushioning device includes a first and a second frame members cross
to each other to form an X-shape structure as seen from side
portion of the resilient cushioning device, the first frame member
and the second frame member each includes an inclined structure
having a front portion and a rear portion, the rear portion of the
first frame member is located above the rear portion of the second
frame member, and the front portion of the first frame member is
located below the front portion of the second frame member. The
rear portion of the first frame member and the front portion of the
second frame member are suspended in the shoe sole, and thus may
include a resilience to cushion and support the heel portions of
the users.
[0009] The first frame member includes a U-shaped structure, as
seen from upper portion thereof, and having a space formed between
two legs. The front portion of the second frame member is extended
upwardly into the space of the first frame member.
[0010] A bladder may further be provided and engaged between the
rear portions of the first frame member and the second frame
member, to cushion the rear portion of the first frame member.
[0011] The front portion of the second frame member includes one or
more reinforcing ribs extended therefrom to reinforce the second
frame.
[0012] Further objectives and advantages of the present invention
will become apparent from a careful reading of the detailed
description provided hereinbelow, with appropriate reference to the
accompanying drawings.

cushioning device for the shoe sole; and
[0017] FIG. 5 is a cross sectional view taken along lines 5-5 of
FIG. 2.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0018] Referring to the drawings, and initially to FIG. 1, a shoe
sole 10 in accordance with the present invention comprises a rear
or heel portion 11 for supporting heel portions of users, a front
portion 12 for supporting front foot portions of the users, and a
resilient cushioning device 20 attached or engaged in the heel
portion 11 of the shoe sole 10 to effectively cushion the heel
portions of the users.
[0019] The resilient cushioning device 20 may be engaged into the
heel portion 11 of the shoe sole 10 while molding the shoe sole 10,
and includes two frame members 30, 40 arranged cross to each other,
in order to form an X-shape structure (FIGS. 1, 5) as seen from the
side portion of the resilient cushioning device 20.
[0020] The first frame member 30 includes an inclined structure
having a rear portion 31 located above the second frame member 40,
and a front portion 32 located below the second frame member 40;
and includes a U-shaped or horseshoe-shaped structure, as seen from
the upper portion thereof (FIG. 2), having a space 33 formed or
defined between two legs 34.
[0021] The second frame member 40 also includes an inclined
structure having a rear portion 41 located below the rear portion
31 of the first frame member 30, and a front portion 42 located
above the front portion 32 of the first frame member 30. The front
portion 42 of the second frame member 40 is extended upwardly
through or into the space 33 of the first frame member 30, best
shown in FIGS. 2-5.
[0022] As also best shown in FIGS. 2-4, the front portion 42 of the
second frame member 40 is preferably slightly shorter than the
front portion 32 of the first frame member 30, and preferably
includes one or more reinforcing ribs 43 extended upwardly
therefrom, for reinforcing the front portion 42 of the second frame
member 40. The frame members 30, 40 may be engaged into the heel
portion 11 of the shoe sole 10 while molding the shoe sole 10.
[0023] In operation, as shown in FIG. 1, due to the engagement or
the molding of the frame members 30, 40 within the heel portion 11
of the shoe sole 10, and due to the inclined structure of the frame
members 30, 40, the rear portion 31 of the first frame member 30
and the front portion 42 of the second frame member 40 are
suspended in the shoe sole 10 and may thus include a suspending
structure, and may thus include a suitable resilience to cushion
and to comfortably support the heel portions of the users.
[0024] The resilient cushioning device 20 may further include a
bladder or a resilient member 50 engaged between the rear portions
31, 41 of the two frame members 30, 40 (FIGS. 1-5); and/or another
bladder or a resilient member 60 engaged between the front portions
32, 42 of the two frame members 30, 40 (FIGS. 1, 5), to further
provide a cushioning force between the two frame members 30, 40,
and thus to further cushion and comfortably support the heel
portions of the users.
[0025] Accordingly, the shoe sole in accordance with the present
invention includes a resilient cushioning device for attaching to
the heel portion thereof to effectively cushion the heel portions
of the users, and thus to comfortably support the heel portions of
the users.
[0026] Although this invention has been described with a certain
degree of particularity, it is to be understood that the present
disclosure has been made by way of example only and that numerous
changes in the detailed construction and the combination and
arrangement of parts may be resorted to without departing from the
spirit and scope of the invention as hereinafter claimed.
