ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a replaceable elastic air cushion shoe structure.
2. Description of the Related Art
A conventional shoe structure in accordance with the prior art comprises a vamp and a sole integrally formed with each other so that the sole and the vamp are fixed and cannot be replaced and removed from each other. A conventional air cushion shoe structure has a constant elastic coefficient and cannot be adjusted so as to fit users of different weights, thereby limiting the versatility of the shoe structure.
SUMMARY OF THE INVENTION
In accordance with one aspect of the present invention, there is provided a replaceable elastic air cushion shoe structure comprising:
a sole having a top provided with a plurality of oblique conical locking grooves, the top of the sole having a periphery provided with a plurality of waterproof ribs, the sole having a periphery defining a plurality of locking recesses each provided with a catch piece;
a vamp having a bottom provided with a plurality of oblique conical locking blocks each locked in the locking groove of the sole, the bottom of the vamp defining a plurality of waterproof slots for receiving the waterproof ribs of the sole therein so that the vamp is integrally formed with the sole;
a plurality of substantially U-shaped snapping pieces each integrally secured in the bottom of the vamp and each having two sides each provided with a hook; and
a plurality of snapping knobs each detachably secured on the snapping piece and each including a press button secured in the locking recess and locked by the catch piece of the sole, and a snap pivotally mounted on the press button and snapped on the hook of the snapping piece.
The sole defines a hollow chamber having a side wall defining an opening having a periphery defining a plurality of snap holes. A cover is removably mounted in the opening and is provided with a plurality of snap lugs each detachably secured in the snap hole of the opening. A magic strap is provided on the cover and the periphery of the opening. A substantially U-shaped elastic steel piece is received in the hollow chamber and has two side plates each defining a large retaining hole, a small retaining hole, and a connecting hole connecting between the large retaining hole and the small retaining hole. A plurality of elastic members are each mounted in the elastic steel piece and each include an upper cap and a lower cap, wherein, the top of the upper cap and the bottom of the lower cap are each provided with a joint and a connecting post. The joint is fitted into the large retaining hole and then shifted into the small retaining hole. The upper cap and the lower cap are each provided with a hollow positioning post, and a spring is mounted between the upper cap and the lower cap and has two ends each secured on the positioning post.
A battery base is secured in the hollow chamber of the sole, and a battery is secured in the battery base. A light emitting member is electrically connected to the battery and has a positive pole wire and a negative pole wire respectively extending through the hollow positioning post of the upper cap and the lower cap so that the light emitting member lights when the positive pole wire and the negative pole wire are moved by the positioning post to electrically connect with each other.
Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.
