Retractable finned footwear used for swimming and walking

Abstract

The present invention is retractable finned footwear comprising an outsole with retractable fins and a lever used to extend and retract the fins. One end of the fins is rotatably connected at back end of the outsole using fastener, while the other end is extended outside from front side of outsole. The fins can be secured at the bottom of the outsole, to facilitate the footwear suitable for walking on land. The fins can be extended from bottom of outsole by pulling the lever positioned at the back end of the outsole. The extended fins provide forward propulsive thrust to user wearing the footwear in water. After using in water, the lever can be pushed to align and secure the fins in line with the outsole. This facilitates the use of footwear both in water and land.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) With the above and other related objects in view, the invention consists in the details of construction and combination of parts as will be more fully understood from the following description, when read in conjunction with the accompanying drawings in which:

(2) FIG. 1 represents a perspective view of retractable finned footwear 100 of present invention showing lever 102 and fins 104 secured under the outsole 106 of the footwear 100 for use in land; and

(3) FIG. 2 represents a perspective view of retractable finned footwear 100 of present invention showing fins 104 retracted out of the outsole 106 for use in water.

DETAILED DESCRIPTION OF THE EMBODIMENTS OF THE INVENTION

(4) FIG. 1 represents a perspective view of retractable finned footwear 100 of present invention. The retractable finned footwear 100 has an outsole 106 comprising at least one fin to result in fins 104 and at least one lever 102 attached to the outsole 106. As shown in FIG. 1, the fins 104 are aligned in line with the outsole 106 of the footwear 100 and can be used for walking on land when the fins 104 are retracted.

(5) FIG. 2 represents a perspective view of retractable finned footwear 100 of present invention showing fins 104 extended out of the outsole 106 for use in water. The outsole 106 has a front end 112 and a back end 114. One end of the fins 104 is rotatably connected at back end 114 of the outsole 106 using at least one fastener 110. The fastener 110 can be, for example a screw that rotatably connects the fins 104 with outsole 106. The other end of fins 104 is extended out from the front end 112 of outsole 106. The fins 104 can be extended out and retracted back in line with the outsole 106, by operating the lever 102. The upper portion 108 of the footwear 100 that covers the upper foot can be of any suitable shape, size and material that suits for both land and water environmental use. Pulling said lever 102 retracts said fins 104 and pushing said lever 102 extends said fins 104.

(6) The fins 104 comprises at least one set of fins, each set comprising at least two fins, for example left fin 122 and right fin 124. Right fin 124 represents the fin at the right side of the footwear 100 and the left fin 122 represents the fin at the left side of the footwear 100. All the sets of fins are arranged one over the other. When the user wearing the footwear 100 wish to walk with the footwear 100, as shown in the FIG. 1, the lever 102 can be pulled to secure all sets of fins together in line with the outsole 106, such that fins 104 will not be visible when seen from the top of the footwear 100.

(7) If the user wishes to use the footwear 100 in water, the user can pull the lever 102, such that each set of fins extend at the sides of the outsole 106. The extended fins 104 spreads at the sides of the outsole 106 one over the other. As shown in FIG. 2, all left fin 122 spreads at left side of the footwear 100 and all right fin 124 spreads at right side of the footwear 100.

(8) It should be noted that the shape and size of the fins 104 are designed such that, when fins 104 are secured under the outsole 106 of the footwear 100, the set of fins takes the shape of the outsole 106. The material of the fins 104 and the footwear 100 are selected such that the user feels light and comfortable both in water and land. Further, the material of the footwear 100 is selected such that, it aids in forward propulsive thrust to user in water. The present invention is useful for eliminating the instability and awkwardness experienced by wearers of conventional swim fins on dry land.

(9) Lever 102 has a suitable locking mechanism that keeps the fins 104 retracted until the lever 102 is pushed. The locking mechanism also keeps the fins 104 extended out of outsole 106 until lever 106 is pulled. The locking mechanism can be, for example, a stopper that holds the position of the fins 104 when extended or aligned with outsole 106. As shown in FIGS. 1 and 2, a mechanical connector 103 is used to connect the lever 102 with the fins 104, such that, through connector 103, the pull or push force is transferred from lever 102 to fins 104. It should be understood that connector 103 extends through outsole 106. That is from the front end 112 to the back end 114.

(10) The foregoing description conveys the best understanding of the objectives and advantages of the present invention. Different embodiments may be made of the inventive concept of this invention. It is to be understood that all matter disclosed herein is to be interpreted merely as illustrative, and not in a limiting sense.
