Description
BACKGROUND OF THE INVENTION
[0001] This application is a continuation of part of U.S. patent
application Ser. No. 10/705,695 filed on Nov. 10, 2003, which
claims the benefit of this earlier filing date.
[0002] 2. Field of the Invention
[0003] The present invention relates to a transparent heel
assembly, and more particularly to an assembling structure for a
transparent heel.
[0004] 2. Description of the Prior Arts
[0005] Based on the prior arts, normally there are two methods of
fixing a transparent heel to a sole. One method is spreading
adhesive directly on the top surface of the heel or on the lower
surface of the sole, and then adhere the heel to the sole. Another
method as shown in FIG. 1, wherein a sole 10 is defined with a
locating hole 12, a top surface of a heel 20 is define provided
with an aperture 17, and then the heel 20 is locked with the sole
10 by virtue of screws 40 and washers 41.
[0006] Since most of the user's weight is loaded on the conjunction
between the heel and the sole, the heel attached to the sole
through adhesive is susceptible to separating after a certain
period of use due to the adhesive is not strong enough. As a
result, not only the service life of the shoe is shortened but also
the user's ankle will be sprained.
[0007] Regarding the method of screwing the heel to the sole, the
heads of the screws will either protrude out or sink into the top
surface of the sole after the screws are screwed in the heel, so
that the top surface of the sole is uneven. The user will feel
uncomfortable after a certain distance of walking. Furthermore, if
the heel is transparent, the screws in the heel can be clearly seen
such that the aesthetic beauty of heel will be adversely
affected.
[0008] The present invention has arisen to mitigate and/or obviate
the afore-described disadvantages of the conventional heel and sole
assembly.
SUMMARY OF THE INVENTION
[0009] The primary object of the present invention is to provide a
transparent heel and sole assembly, wherein the sole is provided
with a locating hole, and a heel is made of transparent marital and
is formed with a protruding closed wall defining a locating groove.
The heel is attached to a lower surface of the sole and the
protruding closed wall is engaged in the locating hole of the sole.
A connecting sheet made of transparent marital and has a connecting
surface on which being formed a protruding engaging column, the
engaging column of the connecting sheet is engaged in the locating
groove of the heel. In this manner, the heel and the sole can be
detachably assembled together in a screwless fashion, so as to save
the assembly time. Furthermore, the connecting sheet and the heel
are made of the same transparent material, therefore, the
connecting sheet will be invisible after being assembled with the
heel.
[0010] The secondary object of the present invention is to provide
a heel and sole assembly, wherein the sole is defined with a
shallow recess for allowing the connecting sheet to flatly abut
against the sole, so as to obviate the disadvantage of the uneven
top surface of the sole and the exposure of the screws caused in
the conventional screwing type transparent heel and sole
assembly.
[0011] The present invention will become more obvious from the
following description when taken in connection with the
accompanying drawings, which shows, for purpose of illustrations
only, the preferred embodiments in accordance with the present
invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0018] Referring first to FIG. 2, wherein a heel and sole assembly
in accordance with the present invention is shown and generally
comprises a sole 10, a heel 20 and a connecting sheet 30.
[0019] The sole 10 is made of transparent material and has an upper
surface 11 facing the user's foot, in the rear end of the upper
surface 11 is formed a shallow recess 12, and in the center of the
recess 12 is defined a locating hole 13. The sole 10 further has a
lower surface 14 and a front upper 15, the front upper 15
corresponds to the back of user's foot. An anti-skid sheet 16 is
arranged on the lower surface 14 of the sole 10.
[0020] In a top surface 21 of the heel 20 is defined a locating
groove 22, so that the heel 20 is attached to the lower surface 14
of the sole 10 in such a manner that the locating groove 22 is
aligned to the locating hole 13 of the sole 10.
[0021] The connecting sheet 30 is also made of the same transparent
material as the sole 10 and is formed on the bottom thereof with a
connecting surface 31 on which being formed a protruding engaging
column 32. The engaging column 32 passes through the locating hole
13 of the sole 10 and then inserts in the locating groove 22 of the
heel 20 in such a manner that the connecting surface 31 of the
connecting sheet 30 abuts closely against the bottom of the shallow
recess 12 in the sole 10. Therefore, the connecting sheet 30 will
be flush with the top surface of the sole 10.
[0022] The heel 20 is attached to the lower surface 14 of the sole
10, and the locating groove 22 is aligned to the locating hole 13
of the sole 10, and then the engaging column 32 of the connecting
sheet 30 is engaged in the locating groove 22 of the heel 20 after
passing through the locating hole 13. In this manner, the heel 20
and the sole 10 can be assembled together easily and firmly in a
screwless fashion. Furthermore, the connecting sheet 30 and the
heel 20 are made of the same transparent material, therefore, the
connecting sheet 30 will be invisible after being assembled with
the heel 20.
[0023] Referring again to FIG. 2, the connecting surface 31 of the
connecting sheet 30 abuts against the bottom of the recess 12 of
the sole 10, and then the engaging column 32 of the connecting
sheet 30 is inserted in the locating groove of the heel 20. In this
way, the disadvantage of the conventional heel and sole assembly,
namely the uneven upper surface 14 of the sole 10 caused by screws
40 will be obviated, and the aesthetic beauty of the transparent
heel 20 is accordingly enhanced.
[0024] Referring to FIGS. 3 and 4, which show a transparent heel
and sole assembly in accordance with a second embodiment of the
present invention. On the top surface 21 of the heel 20 is formed
an upward protruding closed wall 23 that defines a locating groove
22. The protruding closed wall 23 of the heel 20 is inserted in the
locating hole 13 of the sole 10, and then the engaging column 32 of
the connecting sheet 30 is inserted in the locating hole 13 of the
sole 10. In this way, the protruding closed wall 23 of the heel 20
and the engaging column 32 of the connecting sheet 30 are tightly
engaged with each other in the locating hole 13 of the sole 10,
thus enabling the heel 20 and the sole 10 to be assembled together
quickly and firmly without the aid of screws and similar
fasteners.
[0025] Referring to FIGS. 5 and 6, which show a transparent heel
and sole assembly in accordance with a third embodiment of the
present invention. In the engaging column 32 of the connecting
sheet 30 are additionally defined two tenon holes 33, on the bottom
of the locating groove 22 defined by the protruding closed wall 23
are correspondingly arranged two tenons 24. The two tenons 24 of
the heel 20 are inserted in the corresponding tenon holes 33 of the
sole, in this way, the contacting -area between the connecting
sheet 30 and the heel 20 is increased, therefore, the heel 20 and
the sole 10 can be quickly and firmly without the aid of screws and
similar fasteners. The assembly of this embodiment is same as that
of the second embodiment, further remarks on this matter will be
omitted here.
[0026] It will be noted that the principle characteristic of the
present invention as compared to the prior art is that the heel and
the sole are detachably assembled together without the aid of
screws or similar fasteners. Furthermore, the connecting member
(namely the connecting sheet) is made of the same transparent
material as the heel, therefore, the connecting sheet will be
invisible after being assembled with the heel, and this can enhance
the aesthetic beauty of the heel.
[0027] While we have shown and described various embodiments 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.
