Swimming shoe
Abstract
A swimming shoe includes a shoe unit comprising two spaced hook
members pivotably formed on either side, each of the hook members
including a projection on one surface facing either a heel portion
of the shoe unit or a toe portion thereof; and two side boards
hingedly secured to both sides of the shoe unit respectively, each
of the side boards comprising two spaced rectangular through holes
each shaped in conformity to the adjacent hook member. Ends of the
hook members are directly above the through holes. Thereafter,
upward pivoting the side boards to pass the hook members through
the through holes will cause inner surfaces of the through holes to
be lockingly urged by the projections. The ends of the hook members
are adapted to dispose in a position besides the through holes by
pivoting.

Claims
1. A swimming shoe comprising: a shoe unit comprising two spaced
hook members pivotably formed on either side, each of the hook
members including a projection on one surface facing either a heel
portion of the shoe unit or a toe portion thereof; and two side
boards hingedly secured to both sides of the shoe unit
respectively, each of the side boards comprising two spaced
rectangular through holes each shaped in conformity to the adjacent
hook member, wherein ends of the hook members are directly above
the through holes in a first position; whereby from the first
position upward pivoting the side boards to pass the hook members
through the through holes will cause inner surfaces of the through
holes to be lockingly urged by the projections at a second
position; and wherein the ends of the hook members are adapted to
dispose in a third position besides the through holes by
pivoting.
2. A swimming shoe comprising: a shoe unit comprising a hook member
pivotably formed on either side, the hook member including a
projection on one surface facing either a heel portion of the shoe
unit or a toe portion thereof; and two side boards hingedly secured
to both sides of the shoe unit respectively, each of the side
boards comprising a rectangular through hole shaped in conformity
to the adjacent hook member, wherein an end of the hook member is
directly above the through hole in a first position; whereby from
the first position upward pivoting the side boards to pass the hook
members through the through holes will cause inner surfaces of the
through holes to be lockingly urged by the projections at a second
position; and wherein the ends of the hook members are adapted to
dispose in a third position besides the through holes by pivoting.
Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of Invention
[0002] The invention relates to swimming shoes and more
particularly to such a swimming shoe with improved characteristics
including improved efficiency and allowing swimming shoes wearers
to use reasonably the force-exerting portion of the feet while
swimming.
[0003] 2. Description of Related Art
[0004] A conventional swimming shoe or flipper is a device worn on
the foot to increase the thrust of a leg movement in swimming so
that a swimming shoe or flipper wearer can swim relatively easy so
as to last for a longer time.
[0005] However, the desired purposes have not been obtained by the
well known swimming shoes or flippers as the inventor is aware.
[0006] There have been numerous suggestions in prior patents for
swimming shoe or flipper. For example, U.S. Pat. No. 5,151,060
discloses a swimming flipper. Thus, continuing improvements in the
exploitation of swimming shoe or flipper are constantly being
sought.
SUMMARY OF THE INVENTION
[0007] It is therefore one object of the invention to provide a
swimming shoe comprising a shoe unit comprising two spaced hook
members pivotably formed on either side, each of the hook members
including a projection on one surface facing either a heel portion
of the shoe unit or a toe portion thereof; and two side boards
hingedly secured to both sides of the shoe unit respectively, each
of the side boards comprising two spaced rectangular through holes
each shaped in conformity to the adjacent hook member, wherein ends
of the hook members are directly above the through holes in a first
position; whereby from the first position upward pivoting the side
boards to cause the hook members to pass the through holes will
cause inner surfaces of the through holes to be lockingly urged by
the projections at a second position; and wherein the ends of the
hook members are adapted to dispose in a third position besides the
through holes by pivoting.
[0008] The above and other objects, features and advantages of the
invention will become apparent from the following detailed
description taken with the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
[0009] FIG. 1 is a perspective view of a preferred embodiment of
swimming shoe according to the invention where the side boards are
disposed horizontally in one swimming state;
[0010] FIG. 2 is a front view of the swimming shoe;
[0011] FIG. 3 is a view similar to FIG. 2 where the side boards are
disposed about vertically in the other swimming state; and
[0012] FIG. 4 is a view similar to FIG. 1 but the side boards are
disposed about vertically to be worm by the foot for walking.
DETAILED DESCRIPTION OF THE INVENTION
[0013] Referring to FIGS. 1 to 4, a swimming shoe in accordance
with a preferred embodiment of the invention comprises the
following components as discussed in detail below.
[0014] A shoe unit 10 comprises two spaced mating hinge members 11
fixedly formed on either side, and two spaced hook members 12
pivotably formed between the mating hinge members 11 also on either
side.
[0015] Two rectangular side boards 20 are provided on both sides of
the shoe unit 10 respectively. The side board 20 comprises, on one
side facing either side of the shoe unit 10, two spaced
corresponding mating hinge members 21 each together with the mating
hinge member 11 to form a hinge mechanism. The side board 20
further comprises two spaced rectangular through holes 22 between
the corresponding mating hinge members 21 of the same side. Each
through hole 22 is shaped in conformity to the adjacent hook member
12 and disposed corresponding thereto. The hook member 12 comprises
a projection 120 on one surface facing the proximate hinge.
[0016] Prior to walking, a wearer may align the open ends of the
hook members 12 with the through holes 22 so that the wearer may
then pivot the side boards 20 upward to cause the hook members 12
to pass the through holes 22 until the inner surfaces of the
through holes 22 are lockingly urged by the projections 120 (see
FIG. 2). At this position, the side boards 20 are disposed about
vertically.
[0017] As shown in FIGS. 1 to 3, for swimming the wearer may
pivotably push the hook members 12 to cause the open ends thereof
to dispose at a position not aligned with the through holes 22.
Next, the wear may swim. The side boards 20 may pivot between the
position shown in FIGS. 1, 2 and FIG. 3 back and forth while
swimming. It is envisaged by the invention that the swimming shoes
wearer not only feel comfortable but also can fully exert his or
her force with the entire legs while swimming. As a result,
efficiency is greatly increased.
[0018] While the invention herein disclosed has been described by
means of specific embodiments, numerous modifications and
variations could be made thereto by those skilled in the art
without departing from the scope and spirit of the invention set
forth in the claims.
