ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a shoe with a detachable vamp and particularly a shoe with a detachable vamp which may be removed and replaced rapidly and easily without using tools to create versatile alterations for a pair of shoes that are achievable only by owning a plurality of shoes.
A conventional shoe (as shown in
FIG. 1
) generally has a vamp
1
stitched to an insole
2
at a selected location thereof (with a stitching line
3
shown in FIG.
1
), then the insole
2
is bonded to an outsole
4
. The stitching work usually should be done by skilled workers and is labor intensive. It increasingly becomes a big burden to the producers in manpower deployment. Moreover, because of the curved shapes and surfaces of the shoes, it is difficult to increase the stitching speed. As a result, the fabrication process is slow and production costs become higher. In addition, the stitching lines tend to wear off and rupture easily. If the stitching work is not done properly, the stitching lines could be exposed or form uneven thread knots on the insole surface and make wearing the shoe uncomfortable. Once the vamp
1
is damaged, it is not replaceable. All this becomes great disadvantages.
Furthermore, the vamp
1
for conventional sandals and slippers is not changeable by users. To make the sandals and slippers with vamps
1
of different patterns and colors, many different pairs of shoes must be fabricated. It is not appealing to consumers.
Moreover, the producers have to prepare and setup many different molds. This will greatly increase the costs.
SUMMARY OF THE INVENTION
It is therefore an object of the present invention to provide a shoe with a detachable vamp which may be removed and replaced rapidly and easily without using tools to create versatile alterations for a pair of shoes that are achievable only by owning a plurality of shoes.
To attain the foregoing object, the present invention mainly includes a plurality of anchor seats formed by integral injection processing. Each anchor seat has a wedge slot which houses teethed elastic flaps and a connecting flap bridging two elastic flaps. The anchor seat has a side wall which has a round opening to wedge a pushbutton therein. The push button has a strut extended from one side and an annular tenon engaged at one end of the strut for engaging with the round opening securely. A plurality of latch members are provided to fasten a vamp. Each latch member has two latch blades extending downwards. The latch blade also has a teethed surface and may be inserted into the wedge slot to engage with the teethed elastic flap securely. By means of aforesaid construction, the vamp may be attached securely to the sole through the latch members. By pressing the pushbutton, the latch member may be released from the sole to detach the vamp. Hence users can easily change and replace the vamps of different styles and patterns without using any tool. And a pair of shoes may have many different alterations achievable only by many different pairs of conventional shoes.
The foregoing, as well as additional objects, features and advantages of the invention will be more readily apparent from the following detailed description, which proceeds with reference to the accompanying drawings.
