## Abstract

A walker that includes a handle, first frame having first and second legs, a second frame having first and second legs, one or more support bars, and a foldable or stowable foot rest, in which the folding action of the foot rest is actuated via the handle.

## Claims

### Claim 1

A walker with a foldable foot rest, comprising:
a first frame;
a second frame;
a handle having a first end and a second end;
wherein the first frame includes a first leg and a second leg;
wherein the second frame includes a first leg and a second leg;
horizontal support bar connecting the first leg of the first frame to the first leg of the second frame; wherein the at least one horizontal support bar, in turn, includes a first connector and a second connector;
wherein the first connector is adapted to hold in place a first vertical support bar having a top end and a bottom end, and the second connector is adapted to hold in place a second vertical support bar having a top end and a bottom end;
wherein the top end of the first vertical support bar is configured to receive the first end of the handle, and the top end of the second vertical support bar is configured to receive the second end of the handle;
wherein the bottom end of each vertical support bar is pivotally connected, via one or more pivot joints, to a foldable foot rest;
a first top bar connecting an upper end of the first leg of the first frame with an upper end of the second leg of the first frame;
a second top bar connecting an upper end of the second leg of the second frame with an upper end of the second leg of the second frame; and
wherein the folding action of the foot rest is actuated via the handle.

### Claim 2 (depends on 1)

The walker of claim 1, wherein at least one of the first leg and second leg of the first frame includes a rubber ferrule adapted to prevent the walker from slipping.

### Claim 3 (depends on 1)

The walker of claim 1, wherein at least one of the first leg and second leg of the second frame includes a rubber ferrule adapted to prevent the walker from slipping.

### Claim 4 (depends on 1)

The walker of claim 1, wherein when the handle is pulled upwards, the handle engages the foot rest to deploy one or more leg extensions from a bottom surface of the foot rest until the foot rest comes to a horizontal position.

### Claim 5 (depends on 4)

The walker of claim 4, wherein when the handle is pressed downwards, the pivoting action of the foot rest retracts the one or more leg extensions and bring the foot rest to a vertical position.

### Claim 6 (depends on 4)

The walker of claim 4, wherein the one or more leg extensions are adjustable or telescopic.

### Claim 7 (depends on 4)

The walker of claim 4, wherein the one or more leg extensions include rubber ferrules to prevent the foot rest from slipping or to provide cushion to the foot rest when impacting the ground.

### Claim 8 (depends on 1)

The walker of claim 1, wherein the first frame includes one or more bars connecting each leg from the first frame.

### Claim 9 (depends on 1)

The walker of claim 1, wherein the second frame includes one or more bars connecting each leg from the second frame.

### Claim 10 (depends on 1)

The walker of claim 1, wherein each of the first and second top bars include a cushion configured to provide comfort or better grip to a user.

### Claim 11

A walker with a collapsible step, comprising:
a first frame;
a second frame;
a handle having a first end and a second end;
wherein the first frame includes a first leg and a second leg;
wherein the second frame includes a first leg and a second leg;
one or more horizontal support bars connecting the first leg of the first frame to the first leg of the second frame;
wherein the horizontal support bar, in turn, includes a first connector and a second connector;
wherein the first connector is adapted to hold in place a first vertical support bar having a top end and a bottom end, and the second connector is adapted to hold in place a second vertical support bar having a top end and a bottom end;
wherein the top end of the first vertical support bar is configured to receive the first end of the handle, and the top end of the second vertical support bar is configured to receive the second end of the handle;
wherein the bottom end of each vertical support bar is pivotally connected, via one or more pivot joints, to a collapsible step, wherein the collapsible step comprises a foldable top having first and second hingeable portions, a foldable first side having first and second hingeable portions, and a foldable second side having first and second hingeable portions;
a first top bar connecting an upper end of the first leg of the first frame with an upper end of the second leg of the first frame;
a second top bar connecting an upper end of the second leg of the second frame with an upper end of the second leg of the second frame; and
wherein the folding action of the collapsible step is actuated via the handle.

### Claim 12 (depends on 11)

The walker of claim 11, wherein when the handle is pulled upwards, the handle engages the first and second hingeable portions of the foldable top, which, in turn, causes the first and second hingeable portions on the first side and the first and second hingeable portions on the second side to protract, thereby allowing the collapsible step to come to a horizontal position.

### Claim 13 (depends on 12)

The walker of claim 12, wherein when the handle is pressed downwards, the pivoting action of the collapsible step causes the first and second hingeable portions on the foldable top to close or fold, which in turn, causes the first and second hingeable portions on the first side and the first and second hingeable portions on the second side to retract, thereby allowing the collapsible step to achieve a vertical position.

### Claim 14 (depends on 11)

The walker of claim 11, wherein at least one of the first leg and second leg of the first frame includes a rubber ferrule adapted to prevent the walker from slipping.

### Claim 15 (depends on 11)

The walker of claim 11, wherein at least one of the first leg and second leg of the second frame includes a rubber ferrule adapted to prevent the walker from slipping.

### Claim 16 (depends on 11)

The walker of claim 11, wherein the first frame includes one or more bars connecting each leg from the first frame.

### Claim 17 (depends on 11)

The walker of claim 11, wherein the second frame includes one or more bars connecting each leg from the second frame.

### Claim 18 (depends on 11)

The walker of claim 11, wherein each of the first and second top bars include a cushion configured to provide comfort or better grip to a user.
