## Abstract

A cantilevered folding gate (1) may be used with a module (13) which is suitable for fitting in such cantilevered folding gates (1) and includes a transmission mechanism (5) which is accommodated in a housing (14) and which is designed to transmit the movement of a first gate leaf (3) to a second leaf (4) so that the first (3) and second (4) gate leaf open or close simultaneously by folding.

## Claims

### Claim 1

Cantilevered folding gate, comprising:
a column;
a first gate leaf which is hingedly connected to the column;
a second gate leaf which is hingedly connected to the first gate leaf;
drive mechanism designed to drive the first gate leaf;
a transmission mechanism designed to transmit the movement of the first gate leaf to the second leaf so that the first and second gate leaf open or close simultaneously by folding, characterized in that said transmission mechanism is substantially accommodated in a housing which is detachably connected to the first gate leaf, in which the transmission mechanism comprises a first rotatable element and a second rotatable element between which a transmission mechanism is provided and furthermore comprises a first and second entrainment member which are respectively designed to connect the first rotatable element to the column and to connect the second rotatable element to the second gate leaf, in that the column comprises a first retaining unit which is designed to accommodate an end of the first entrainment member so that the first rotatable element, in use, cannot rotate with respect to the column, and in that the second gate leaf comprises a second retaining unit which is designed to accommodate an end of the second entrainment member so that the second rotatable element, in use, cannot rotate with respect to the second gate leaf.

### Claim 2 (depends on 1)

Cantilevered folding gate according to claim 1, characterized in that said first element is an element which is connected to the column and which is provided with a toothing along at least part of its outer periphery, and in that the second rotatable element which is connected to the second gate leaf is provided with a toothing along at least part of its outer periphery, in which the gate furthermore comprises a transmission mechanism which is provided with a toothing at both its ends, with one end being designed to roll over the teeth of the first element and with the teeth of the other end meshing with the teeth of the second rotatable element.

### Claim 3 (depends on 1)

Cantilevered folding gate according to claim 1, characterized in that the first gate leaf is connected to the column via a first set of hinges, and in that the second gate leaf is connected to the first gate leaf via a second set of hinges.

### Claim 4 (depends on 3)

Cantilevered folding gate according to claim 3, characterized in that the distance between the axes of rotation of the first and second rotatable element, respectively, is equal to the distance between the axes of rotation of the first set of hinges and the axes of rotation of the second set of hinges.

### Claim 5 (depends on 3)

Cantilevered folding gate according to claim 3, characterized in that the housing is connected to the first gate leaf in such a manner that the axis of rotation of the first rotatable element coincides with the axis of rotation of the first set of hinges and that the axis of rotation of the second rotatable element coincides with the axis of rotation of the second set of hinges.

### Claim 6 (depends on 1)

Cantilevered folding gate according to claim 1, characterized in that the first and second element is a gearwheel.

### Claim 7 (depends on 1)

Cantilevered folding gate according to claim 1, characterized in that the pitch diameter of the first element is twice as large as the pitch diameter of the second rotatable element.

### Claim 8 (depends on 1)

Cantilevered folding gate according to claim 1, characterized in that the transmission mechanism is a gear rack.

### Claim 9 (depends on 1)

Module suitable for fitting in a cantilevered gate according to claim 1, wherein said module comprises a transmission mechanism which is accommodated in a housing and is designed to transmit the movement of a first gate leaf to a second leaf so that a first and second gate leaf can open or close simultaneously by folding.

### Claim 10 (depends on 9)

Module according to claim 9, characterized in that the transmission mechanism comprises a first rotatable element and a second rotatable element and furthermore comprises a first and second entrainment member which are respectively designed to connect the first element to the column and to connect the second rotatable element to the second gate leaf, in that the column comprises a first retaining unit which, is designed to accommodate the first entrainment member so that the first rotatable element, in use, cannot rotate with respect to the column, and in that the second gate leaf comprises a second retaining unit which is designed to accommodate the second entrainment member so that the second rotatable element, in use, cannot rotate with respect to the second gate leaf.

### Claim 11 (depends on 9)

Module according to claim 9, characterized in that the housing is made of plastic or metal.

### Claim 12 (depends on 9)

Module according to claim 9, characterized in that the housing can be connected to the first gate leaf via a screw connection.

### Claim 13 (depends on 9)

Module according to claim 9, characterized in that said module furthermore comprises a heating element.

### Claim 14
