Dual functions outsole structure for use on level and sloping ground

Abstract

A dual function outsole structure for use on level and sloping ground is disclosed. The outsole structure is provided with a recess for the mounting of a base plate with a rotation seat. The base plate is hidden within the outsole and the rotation seat is pivotally mounted to the two corresponding securing plates on the base plate. The rotation seat is provided with a plurality of shoe spikes and the two lateral sides of the rotation seat are provided with an elastically trigger anti-return bolt. Under normal situation one end of the anti-return bolt engages with a positioning hole provided on the securing plate such that the rotation seat is positioned. In view of the above components, under normal situation the shoe spike is hidden at the recess of the outsole and is suitable for waling on a level ground (such as on a tar road, pavement road surface or a cement road). If the anti-return bolt is triggered and one end of the bolt is retreated from the engaging position, the rotation seat rotates to an appropriate angle and is then positioned. Thus, the shoe spikes are protruded to provide a deeper ground-gripping force and allows safety walking on sloping ground, refraining from falling into ravine, valley.

I claim:  
     
         1 . A dual function outsole structure for use on level and sloping ground characterized in that a recess is provided on the outsole and the recess is for the mounting of a base plate with a rotation seat, and the base plate is hidden within the outsole, and the rotation seat is pivotally mounted onto a securing plate on the base plate, the rotation seat is provided with a plurality of shoe spikes, and the rotation seat and the securing plate are provided with engaging positioning device; the shoe spikes are hidden within the recess of the outsole for normal walking on a level ground, and if the rotation seat is returned from the engaging position, the rotation seat rotates to an angle for positioning.  
     
     
         2 . The outsole structure of  claim 1 , wherein the engaging positioning device is a securing plate provided with two positioning holes and the two ends of the rotation seat are protruded with a rotation shaft extended into the rotation shaft hole of the securing plate to form into a rotational pivot, the rotational seat is provided with an anti-return bolt and an elastic element such that one end of the anti-return bolt is protruded outside the rotational seat, forming into elastic condition, one end protruded from the anti-return bolt is engaged at a positioning hole, and the anti-return bolt is provided with a trigger rod protruded outside the rotation seat and is slidable within a sliding slot on the surface of the rotation seat.  
     
     
         3 . The outsole structure of  claim 1 , wherein the bottom section of the rotation seat is provided with a guiding corner such that the rotation seat smoothly rotates at an inclination facing the recess.  
     
     
         4 . The outsole structure of  claim 1 , wherein the recess is provided to the sole position at the front section of the outsole and the heel section of the rear section of the outsole.  
     
     
         5 . The outsole structure of  claim 1 , wherein the engaging positioning device includes a rotation seat having a near end portion provided with a notch, and an engaging block is provided with corresponding protrusion and is pivotally mounted within the notch and can be flipped, and the tail end of the engaging block is provided with an extension portion in contact with the inner wall of the notch, and the material of the rotation seat is a soft material, and the two ends of the rotation seat are protruded to form a rotation shaft protruded to the rotation shaft hole of the securing plate to form a rotatable pivot connection, and the top and the side of the securing plate are provided with an engaging slot for the end portion of the front end of the engaging block to be engaged so as to provide the effect of engagement of the engaging block.
