## Abstract

Stabilizer support for crutches and/or walking sticks, comprising a cylindrical body (1) with vertical axis within which there is a seat destined to receive a portion of a crutch or walking stick (S). The stabilizer support comprises more extractable feet (5) which, in a retracted position, are vertical and are inside the said body (1) while, in the extracted position, are spread apart and are external to the said body (1) thus forming a stable base of the stabilizer support. Furthermore, the stabilizer support comprises a knob (6) through which a slide (4) is made to vertically move inside the said body (1), the said feet (5) being connected with the said slide (4).

## Claims

### Claim 1

A stabilizer support for crutches and/or walking sticks, comprising:
a tubular element for receiving a portion of a crutch or walking stick;
a cylindrical body with a vertical axis arranged around said tubular element;
extractable feet movable between a retracted position and an extracted position, said extractable feet being vertical and inside said cylindrical body in said retracted position, said extractable feet being spread apart and external to said cylindrical body in said extracted position to form a stable base of the stabilizer support; and
a slide vertically movable inside said cylindrical body, said extractable feet being connected with said slide;
a knob connected to said slide and movable with said slide;
a radial elastic plug mounted on a surface of said slide for locking said slide to said tubular element, said tubular element having two radial cavities, one of said radial cavities being near a top portion of said tubular element and another one of said radial cavities being adjacent to a lower base of said tubular element, said radial cavities being engaged by the plug when the slide is in a raised or lowered position.

### Claim 2 (depends on 1)

A stabilizer support according to claim 1, wherein said tubular element is internal and coaxial to said cylindrical body and said tubular element comprises a lower discoid base, said lower discoid base comprising three angularly equidistant holes with vertical axis and said lower discoid base forms the lower base of said cylindrical body.

### Claim 3 (depends on 2)

A stabilizer support according to claim 2, wherein an upper base of said cylindrical body has a central hole arranged around said tubular element, an upper portion of said tubular element protrudes above the upper base of the cylindrical body.

### Claim 4 (depends on 2)

A stabilizer support according to claim 2, wherein said slide consists of a ring free to slide along said tubular element.

### Claim 5 (depends on 1)

A stabilizer support according to claim 1, wherein an upper base of said cylindrical body has a central hole arranged around said tubular element, an upper portion of said tubular element protrudes above the upper base of the cylindrical body.

### Claim 6 (depends on 5)

A stabilizer support according to claim 5, wherein said upper portion of said tubular element is threaded and a threaded ring is screwed on said upper portion to lock the crutch or walking stick to said tubular element when using the stabilizer support.

### Claim 7 (depends on 1)

A stabilizer support according to claim 1, wherein said cylindrical body has a longitudinal slit through which passes a stem, said stem connecting said knob to the slide.

### Claim 8 (depends on 1)

A stabilizer support according to claim 1, wherein said slide consists of a ring free to slide along said tubular element.

### Claim 9 (depends on 1)

A stabilizer support according to claim 1, wherein said extractable feet are made by rods, said extractable feet being three in number and said extractable feet are connected to the slide in angularly equidistant positions.

### Claim 10

A stabilizer support for crutches and/or walking sticks, comprising:
a tubular element for receiving a portion of a crutch or walking stick;
a cylindrical body with a vertical axis arranged around said tubular element;
extractable feet movable between a retracted position and an extracted position, said extractable feet being vertical and inside said cylindrical body in said retracted position, said extractable feet being spread apart and external to said cylindrical body in said extracted position to form a stable base of the stabilizer support; and
a slide vertically movable inside said cylindrical body, said extractable feet being connected with said slide;
a knob connected to said slide and movable with said slide;
said tubular element is internal and coaxial to said cylindrical body and said tubular element comprises a lower discoid base, said lower discoid base comprising three angularly equidistant holes with vertical axis and said lower discoid base forms the lower base of said cylindrical body;
an upper base of said cylindrical body has a central hole arranged around said tubular element, an upper portion of said tubular element protrudes above the upper base of the cylindrical body.

### Claim 11 (depends on 10)

A stabilizer support according to claim 10, wherein a radial elastic plug is mounted on a surface of said slide for locking said slide to said tubular element, said tubular element having two radial cavities, one of said radial cavities being near a top portion of said tubular element and another one of said radial cavities being adjacent to a lower base of said tubular element, said radial cavities being engaged by the plug when the slide is in a raised or lowered position.

### Claim 12

A stabilizer support for crutches and/or walking sticks, comprising:
a tubular element for receiving a portion of a crutch or walking stick;
a cylindrical body with a vertical axis arranged around said tubular element;
extractable feet movable between a retracted position and an extracted position, said extractable feet being vertical and inside said cylindrical body in said retracted position, said extractable feet being spread apart and external to said cylindrical body in said extracted position to form a stable base of the stabilizer support; and
a slide vertically movable inside said cylindrical body, said extractable feet being connected with said slide;
a knob connected to said slide and movable with said slide;
said tubular element is internal and coaxial to said cylindrical body and said tubular element comprises a lower discoid base, said lower discoid base comprising three angularly equidistant holes with vertical axis and said lower discoid base forms the lower base of said cylindrical body;
a radial elastic plug mounted on a surface of said slide for locking said slide to said tubular element, said tubular element having two radial cavities, one of said radial cavities being near a top portion of said tubular element and another one of said radial cavities being adjacent to a lower base of said tubular element, said radial cavities being engaged by the plug when the slide is in a raised or lowered position.
