Description
BACKGROUND OF THE INVENTION
1. Fields of the Invention
[0001] The present invention relates to a shoe, and more
particularly, to a shoe with a replaceable heel.
2. Descriptions of Related Art
[0002] There are many different types of shoes which have different
purposes and functions, such as mountain shoes, jogging shoes,
walking shoes, basketball shoes . . . etc., all of the shoes
generally comprise an outsole which is directly in contact with the
ground so that the outsole is worn out because of friction. The
heel is an important portion of shoes and the heel usually is the
first part that is worn out before the rest portion does. Once the
heel is worn out, deformed or cracked, the shoe has to be replaced
with a new one. It is noted that most of the shoes that are
discarded still have their vamp and other portions in good shape,
the only portion that loses its function is the heel. To purchase
new pairs of shoes may cost a lot and the shoes need a lot of space
to store.
[0003] The present invention intends to provide a shoe with a
replaceable heel to eliminate the shortcomings mentioned above.
SUMMARY OF THE INVENTION
[0004] The present invention relates to a shoe and comprises an
outsole, a shank and a heel area defined in the underside of the
shoe. The shank is connected between the outsole and the heel area.
The heel area is a recessed area. A replaceable heel has a
connection portion which is located at the top of the replaceable
heel and detachably connected to the heel area. A heel lift is
defined in the underside of the replaceable heel, and multiple
anti-slip members extend from the heel lift.
[0005] Preferably, the shank has a protruded portion which extends
toward the heel area. The replaceable heel has an engaging end and
a pull end, wherein the engaging end is matched with the protruded
portion, and the pull end protrudes beyond the rear end of the heel
area.
[0006] Preferably, the heel area is tapered from a rear end thereof
toward the protruded portion. The thickness of the protruded
portion is thicker than that of the engaging end.
[0007] Preferably, the heel area has a hook-surface formed thereon.
The connection portion of the replaceable heel has a loop-surface
which is connected to the hook-surface of the heel area.
[0008] Preferably, the anti-slip members have spikes extending
therefrom.
[0009] Preferably, the anti-slip members have cylindrical
protrusions extending therefrom.
[0010] The present invention will become more obvious from the
following description when taken in connection with the
accompanying drawings which show, for purposes of illustration
only, a preferred embodiment in accordance with the present
invention.

protrusions.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0020] Referring to FIGS. 1 to 9, the shoe 1 of the present
invention comprises an outsole 11, a shank 12 and a heel area 13
defined in the underside of the shoe 1, and the shank 12 is
connected between the outsole 11 and the heel area 13. The heel
area 13 is a recessed area. A replaceable heel 2 has a connection
portion 21 which is located at the top of the replaceable heel and
detachably connected to the heel area 13. A heel lift 22 is defined
in the underside of the replaceable heel 2, wherein multiple
anti-slip members 3 extend from the heel lift 22.
[0021] As disclosed in FIGS. 1 to 7, the shank 12 has a protruded
portion 121 which extends toward the heel area 13. The replaceable
heel 2 has an engaging end 23 on the front end thereof, and a pull
end 24 on the rear end thereof The engaging end 23 is matched with
the protruded portion 121, and the pull end 24 protrudes beyond the
rear end of the heel area 13. The heel area 13 is tapered from the
rear end thereof toward the protruded portion 121, and the
thickness of the protruded portion 121 is thicker than that of the
engaging end 23. The different thickness between the protruded
portion 121 and the engaging end 23 allows the user to easily aim
and match the protruded portion 121 with the engaging end 23. The
engaging end 23 is a recessed end which is located between two
protruding portions, so that the two recesses between the protruded
portion 121 restrict the two protruding portions of the replaceable
heel 2, so that the replaceable heel 2 does not drop from lateral
direction of the shoe 1. When removing the replaceable heel 2, the
user simply pushes the pull end 24 that protrudes beyond the rear
end of the heel area 13 and separates the replaceable heel 2 from
the shoe 1.
[0022] As shown in FIGS. 4 to 7, the heel area 13 is tapered from
the rear end thereof toward the protruded portion 121, so that when
the replaceable heel 2 is connected to the heel area 13 of the shoe
1, the thickness of the protruded portion 121 is thicker than that
of the engaging end 23, so that when stepping on pebbles on the
road, the pebbles do not contact the engaging end 23 of the
replaceable heel 2 and replaceable heel 2 does not separated from
the shoe 1 by the pebbles.
[0023] As shown in FIGS. 2 and 3, the heel area 13 has a
hook-surface 131 formed thereon, the connection portion 21 of the
replaceable heel 2 has a loop-surface 211 which is connected to the
hook-surface 131 of the heel area 13 to connect the replaceable
heel 2 to the shoe 1.
[0024] As shown in FIGS. 8 and 9, the anti-slip members 3 have
spikes 31 or cylindrical protrusions 32 extending therefrom. The
replaceable heel 2 can also be a cushion heel or any known heel
according need.
[0025] By the replaceable heel 2, the users can change the
replaceable heel 2 as needed so that the users do not need to
purchase too many pairs of shoes.
[0026] While we have shown and described the embodiment in
accordance with the present invention, it should be clear to those
skilled in the art that further embodiments may be made without
departing from the scope of the present invention.
