Abstract

A shoe usable for walking or roller skating is disclosed wherein the roller skating means is contained within the sole of the shoe. The skating means is selectively engageable so that the shoe can be used with little effort for either mode of transportation.

Claims

1. A roller- and walking-shoe comprising:

a sole enlarged in thickness defining a cavity; and

a roller mechanism mounted in said cavity, said roller mechanism comprising;

a plurality of rollers mounted on axles, a mounting means connecting said axles with said sole such that said rollers can selectively extend downwardly below said sole or be retained within said sole, a locking means to hold said mounting means in position when said rollers are extended, and at least one spring connected between said mounting means and said sole to pull and retain said mounting means into said cavity.

2. The roller- and walking-shoe according to claim 1, wherein the mounting means comprises two collinear levers, each approximately centrically pivoted and having said axle affixed at the outermost end;

and the locking means comprises the first of said two collinear levers having the end opposite said axle notched and the second of said two collinear levers having at the end opposite said axle a protrusion with the end of said protrusion notched whereby when the mounting means is in a retracted position, said protrusion of said second lever rests in the notch of said first lever and when said mounting means is in an extended position, a protrusion formed by the notch of said first lever fits in the notch on the end of a protrusion of said second lever thereby locking said mounting means extending downwardly below said sole.

3. The roller- and walking-shoe according to claim 2, wherein said roller mechanism is fixedly positioned on a support member which is removable from said cavity.

4. The roller- and walking-shoe according to claim 3, wherein said support member is in the shape of a U in the direction perpendicular to the length of said sole and the open side of the U-faces downwardly.

5. The roller- and walking-shoe according to claim 1, wherein said mounting means comprises a plurality of levers connected such that the action of all axles is forcibly coupled.

6. The roller- and walking-shoe according to claim 1, wherein said roller mechanism is fixedly positioned on a support member which is removable from said cavity.

7. The roller- and walking-shoe according to claim 6, wherein said support member is in the shape of a U in the direction perpendicular to the length of said sole and the open side of the U-faces downwardly.

8. The roller- and walking-shoe according to claim 1, wherein the locking means comprises a step-switch and an activating member.
