Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates generally to footwear, and more particularly to easily removing the entire heel to allow different styles, colors, and
The present invention relates to a shoe structure that can be replaced with a heel having height, width or other characteristics.

[0002]

BACKGROUND OF THE INVENTION In the field of footwear, especially women's shoes, there is a need to economically utilize footwear and make it more versatile. For example, flatter heel shoes are suitable for more casual clothes, while high heel shoes are suitable for more formal clothes. In addition, the heel style may need to be changed. The style of shoes also depends on the type of action plan of the person who wears them. A wider heel is more comfortable when walking a considerable distance.
But if you're attending a night out, the heel style should be narrower and more elegant.

If the size, height, shape, or style of the heel is not fixed, the upper of a shoe will be more useful. That is, obtaining and storing a collection of shoes to adapt to changing conditions is extremely expensive.

Accordingly, it has been recognized in the prior art how to replace the heel portion of a shoe to meet the need to economically match footwear to clothing. That is, you don't have to buy a large amount of handheld shoes, but instead just replace it with a new heel at a significantly lower cost, to achieve the desired "look" and / or comfort factor. be able to.

Although some replaceable heels are known, there is still a need for improved heel construction. For example, some interchangeable heels are difficult to manufacture because some of the finer parts need to be assembled into the core of the heel. Similarly, in conventional replaceable heel shoes, the heel is an integral part of the shoe to the wearer, as manufacturing tolerances or wear may cause the heel and the shoe to move more or less relative to each other. There is a need to continue improving to get the feel. Similarly, the fixing means to the shoe sole tends to tilt with respect to the sole because the direction of the force transmitted from the heel to the sole via the connecting mechanism is different.
It becomes uncomfortable for the wearer.

[0006]

SUMMARY OF THE INVENTION Accordingly, the basic object of the present invention is to provide an improved shoe construction in which the heel member or a portion thereof can be easily removed and replaced to change the style of the sole. To do. Another object is to provide a shoe construction whose style, height, thickness and other characteristics can be easily modified. Yet another purpose is to remove the heel part instantly without using any special tools.
To provide exchangeable shoes.

[0007]

SUMMARY OF THE INVENTION A shoe constructed in accordance with the present invention is a conventional shoe having a sole and an outwardly projecting pin attached by a non-circular head to the heel of the sole. It has an upper. Extending longitudinally through the core of the heel is a hole for receiving a pin, a socket, a groove, or a cavity surrounding the hole at the top of the heel. The cavity is sized to receive a non-circular head protruding from the upper of the shoe. This allows the heel to be pushed onto the pin and the head to fit into the socket. The non-circular structure prevents relative rotation of the heel and the upper of the shoe. The heel incorporates a latch that engages the pin and prevents the heel from disengaging unless the user appropriately moves the position of the latch. In another, more particular embodiment of the present invention, the above problem is solved by providing a capsule-shaped lock that can be fixed to either the upper of the shoe or the heel. The capsule lock is displaced against the lower surface of the plate located inside the housing,
It includes a washer member of a lock member extending at an acute angle, the size of the opening of the washer member is such that when the opening is aligned with the pin member, the pin member of the upper can pass through the opening and the opening is the pin member. If not aligned, it is sized to constrain the pin member.

The shoe according to the invention is simple, easy and quick to remove and replace with a different heel, is easy to manufacture and ensures that the heel is firmly fixed to the upper for the wearer. It has the advantage that it does not come off the instep or move relative to the instep.

Is vertically aligned with the pin 18 so that the pin 18 can pass through the opening of the washer member 214. When the head portion 20 is slidably fitted in the cavity 22 and joins with the bottom of the cavity, the heel 16 is prevented from further movement in the insertion direction. Since the washer 214 restrains the pin 18 and prevents relative movement between the two, the heel 16 is also prevented from moving in the opposite or withdrawal direction. In this way, the heel 16 is fast, accurate, yet firmly and firmly secured to the upper 10.

Wearing the shoe 10 according to the present invention ensures the comfort and robustness of the heel and upper combination. The movement of pulling them apart is prevented as described above. The head portion 20 is fitted with a clearance into the conforming shape of the cavity 22, the joining surface 242 of the cylindrical portion 240 of the head portion.
Is an acute angle, and the upper surface of the plate 230 is the capsule lock 20.
Due to the shape to fit snugly within 0 and the ears 264 and 250 in combination with the troughs 248 and 268, relative rotational or twisting movements are prevented. The ears 264 and 250 and the troughs 248 and 268 additionally additionally prevent tilting or other three-dimensional rotational movement.

A preferred embodiment has been described which specifically illustrates the basic structure of the shoe 10 according to the present invention. However, it will be obvious to the expert that many extensions, changes and modifications and other combinations are possible. Although not limited thereto, for example, the pin 18 and head portion 20 have been described as attached to the upper 10 and include a cavity 22 into which the heel 16 fits, but the pin 18 and head portion 20 are not limited to this. It is also within the scope of the present invention to attach to 16 and provide a cavity 22 in the upper 10. Similarly, the various conforming parts can be shaped differently. The scope of the invention is, therefore, selected and limited by the appended claims rather than by the particularly preferred embodiments described.
