## Abstract

A new Reduced Impact Cane for absorbing the impact of a cane striking against an unyielding surface. The inventive device includes a cane having a end, a spring connector, a connecting sleeve disposed around the cane end and spring connector, a collar disposed around the lower end of the spring connector, a rubber tip disposed around the collar, and a spring interposed between the lower end of the spring connector and the rubber tip.

## Claims

### Claim 1

A reduced impact cane attachment, comprising:
a cane having an end;
a tip; and
a reduced impact means including:
a spring connector having first end and a second end;
a connecting sleeve having a first end and a second end, said connecting sleeve first end being disposed around said cane end, said connecting sleeve second end being disposed around said first end of said spring connector;
a collar being disposed around said second end of said spring connector, said tip being disposed around said collar;
a spring being accepted by second end of said spring connector and said spring being coupled to said rubber tip;
wherein said connecting sleeve second end includes a ridge, said ridge being accepted by said first end of spring connector;
wherein said connecting sleeve first end includes an other ridge, said other ridge being accepted by said cane end.

### Claim 2

A reduced impact cane attachment, comprising:
a spring connector having first end and a second end;
a connecting sleeve having a first end and a second end, said connecting sleeve second end being disposed around said first end of said spring connector;
a collar disposed around said second end of said spring connector;
a tip having a first end, said first end of said tip being disposed around said collar;
a spring being accepted by second end of said spring connector and said spring being coupled to said tip; and
wherein said connecting sleeve second end includes a ridge, said ridge being accepted by said first end of spring connector.

### Claim 3 (depends on 2)

The reduced impact cane attachment of claim 2, wherein said first end of said first end of said connecting sleeve is adapted to accept a cane.

### Claim 4 (depends on 3)

The reduced impact cane attachment of claim 3, further comprising a cane having an end, said first end of said connecting sleeve being disposed around said end of said cane.

### Claim 5 (depends on 2)

The reduced impact cane attachment of claim 2, wherein said connecting sleeve is frictionally coupled to said first end of said spring connector.

### Claim 6 (depends on 2)

The reduced impact cane attachment of claim 2, wherein said spring connector is made of wood and said spring is coupled to said spring connector by means of a screw.

### Claim 7 (depends on 2)

The reduced impact cane of claim 2, wherein said collar is made of metal.

### Claim 8 (depends on 2)

The reduced impact cane of claim 2, wherein said spring is interposed between said second end of said spring connector and said first end of said tip.

### Claim 9 (depends on 2)

The reduced impact cane attachment of claim 2, wherein said connecting sleeve first end includes an other ridge, said other ridge being accepted by said cane end.

### Claim 10

A reduced impact cane, comprising:
a cane having an end;
a spring connector being made of wood and having first end and a second end;
a connecting sleeve being made of rubber and having a first end accepting said cane and a second end including a ridge, said first end of said connecting sleeve being disposed around said end of said cane, said second end of said connecting sleeve disposed around said first end of said spring connector, said ridge being accepted by said first end of spring connector, and said connecting sleeve being frictionally coupled to said first end of said spring connector and said end of said cane;
a collar disposed around said second end of said spring connector;
a rubber tip having a first end, said first end of said rubber tip being disposed around said collar;
a spring interposed between said second end of said spring connector and said first end of said rubber tip, said spring being accepted by second end of said spring connector, said spring being coupled to said spring connector by means of a screw, and said spring being coupled to said rubber tip; and
said collar is made of steel.
