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 including a lower frame member, and an upper
frame member supported above the lower frame member, and suspended
in the shoe sole, to provide a resilience to cushion and support
the heel portions of the users.
[0009] The lower and the upper frame members include an
intermediate portion coupled together with such as a stay.
[0010] A resilient member may further be provided and engaged
between rear portions of the lower frame member and the upper frame
member, to cushion the rear portion of the lower frame member.
Another resilient member may further be provided and engaged
between front portions of the lower frame member and the upper
frame member, to cushion the front portion of the upper frame
member.
[0011] The lower frame member includes a rear portion having a
U-shaped structure, and the lower frame member may include a front
portion having a flat planar structure. The upper frame member
includes a rear portion having a O-shaped structure, and the upper
frame member may include a front portion having a flat planar
structure. The upper frame member includes a front portion having
an opening formed therein.
[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.
BRIEF DESCRIPTION OF THE DRAWINGS
[0013] FIG. 1 is a side schematic view of a shoe sole in accordance
with the present invention;
[0014] FIG. 2 is a top plan view of a resilient cushioning device
for the shoe sole;
[0015] FIG. 3 is a bottom plan view of the resilient cushioning
device for the shoe sole;
[0016] FIG. 4 is a rear perspective view of the resilient
cushioning device for the shoe sole; and
[0017] FIG. 5 is a rear perspective view similar to FIG. 4, having
dotted lines to show an inner structure of the resilient cushioning
device for the shoe sole.
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 a substantially I or Z-shape structure (FIGS. 1,
4, 5) as seen from the side portion of the resilient cushioning
device 20.
[0020] The first or the lower frame member 30 is located below the
other or the upper frame member 40. Each of the frame members 30,
40 includes a rear portion 31, 41, a front portion 32, 42, and an
intermediate portion 33, 43; in which the intermediate portions 33,
43 of the frame members 30, 40 are coupled or secured together by
such as molding or extruding or mold injection processes, so as to
form the Z-shape structure (FIGS. 1, 4, 5).
[0021] For example, the intermediate portions 33, 43 of the frame
members 30, 40 are coupled or secured together by a stay 47 that
may also be formed integral with the frame members 30, 40 with such
as the molding or extruding or mold injection processes, in order
to resiliently support the upper frame member 40 above the lower
frame member 30.
[0022] The rear portion 31 of the lower frame member 30 includes a
substantially U-shaped structure (FIG. 3), and the front portion 32
of the lower frame member 30 includes a substantially flat planar
structure. The rear portion 41 of the upper frame member 40
includes a substantially O-shaped structure (FIG. 2), and the front
portion 42 of the upper frame member 40 also includes a
substantially flat planar structure having an opening 44 formed
therein.
[0023] As shown in the drawing figures, the front portion 42 of the
upper frame member 40 is preferably slightly shorter than the front
portion 32 of the lower frame member 30. The frame members 30, 40
may be engaged into the heel portion 11 of the shoe sole 10 while
molding the shoe sole 10.
[0024] 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 resilient support of the upper
frame member 40 above the lower frame member 30, the upper frame
member 40 may be 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.
[0025] 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, and/or another bladder or
resilient member 60 engaged between the front portions 32, 42 of
the two frame members 30, 40, 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.
[0026] 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.
[0027] 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.
