STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENTNot applicable.
BACKGROUND1. Technical Field
The present invention relates generally to the field of footwear. Still more particularly, the illustrative embodiments are directed to a lady's shoe with quick replacement of heels of various heights so that the same shoe is used for various needs and occasions.
2. Background
Efforts have been made to provide a replaceable worn out heel for ladies' or men's shoes with some fastening means. However, the prior efforts have not been able to meet the challenges to provide the security and stability and quick replacements of heels of various heights. Women normally commute to work with low heel shoes and sometimes wear medium heel shoes during work, and they may wear a high heel shoe for an evening or a formal occasion. The present invention provides a lady's shoe (a boot or other footwear) with a plurality of mechanical coupling mechanisms for coupling heels of various heights to the sole of the same shoe. For example: a low height heel, a medium height heel, or a high height heel with a quick heel replacement suitable for regular walks or formal occasions. The reference to a lady's shoe in this invention is applicable to various types of boots or other footwear.
SUMMARY OF THE INVENTIONThis disclosure provides a lady's shoe (a boot or other footwear) with a plurality of mechanical coupling mechanisms for coupling heels of various heights to same the shoe. This will provide for convenience and better efficiency for a busy working woman. For example, a low height heel, a medium height heel, or a high height heel with quick heel replacement suitable for regular walks or formal occasions. Also it is more economical solution to have one pair of shoes for all occasions. This solution can apply to new production or retrofit existing shoes. In view of the foregoing, it is an object of the present invention to provide a lady's shoe with a plurality of coupling mechanisms for coupling heels of various heights to a lady's shoe so that the same shoe is used for various purposes.
It is another objective of the present invention to provide a lady's shoe equipped with a heel replacement fixture for replacing heels of various heights.
It is another objective of the present invention to provide a lady's shoe equipped with a fixture for replacing heels of various heights. The mechanism to couple or decouple a top part of the heel fixture to a bottom part of the heel replacement fixture is a mechanical coupling mechanism. The mechanical coupling mechanism comprises of grooved sliding surfaces, locking arms and drop pins attached to the top part of the heel replacement fixture into a pin receiving anchors or latches which are attached to the bottom part of the fixture to secure and lock the two parts of the heel replacement fixture.
It is another objective of the present invention to provide a mechanism for a lady's shoe to couple the top part of the heel replacement fixture to the bottom part of the heel replacement fixture with a latch spring mechanism. The latch spring mechanism comprises a plurality of spring attached to the latch, and the latch spring mechanism is further attached to the bottom part of the heel replacement fixture which in turn is attached to the replaceable heel of the lady's shoe.
It is another objective of the present invention to provide a mechanism for a lady's shoe to couple the top part of the heel fixture to the bottom part of the heel replacement fixture is a push button mechanism. The push button mechanism is attached to the bottom part of the heel replacement fixture which in turn is attached to the replaceable heel of the lady's shoe. The push button mechanism comprises a rod with a spring attached to a lever rod which will act as a tongue latch in a slot in the top part of the heel replacement fixture to secure the coupling of the two heel replacement fixture parts.
It is another objective of the present invention to provide a mechanism for a lady's shoe to couple the top part of the heel replacement fixture to the bottom part of the heel replacement fixture, where the heel replacement fixture fabrication material includes stainless steel, tempered aluminum alloy, a durable polymer, or a light weight composite material.
It is another objective of the present invention to provide a mechanism for a lady's shoe the heels of various heights. The heel of various heights include a low height heel ranges between 0.25 to 1.00 inch in height, the medium height heel ranges between 1.00 to 3.0 inches in height, and the high heel ranges between 3.00 to 5.00 inches.
The numerous innovative teachings of the present application will be described with particular reference to presently preferred embodiments.
