Description

FIELD OF INVENTION The present invention relates generally to the field of entrance gates for driveways. BACKGROUND ART Entrance gates are generally hinged on a wall or pillar to swing outwards or inwards. The gate requires space to swing open, thereby the area where the gate swings must be clear from obstructions for to move freely. Where space is limited the angle at which the gate can swing open will be restricted. Further, for a swing gate to operate freely in either direction, it needs to on a level surface. If it is on an inclined ground, the opening angle of the gate towards the higher section of the incline will be restricted. As the base of the gate will hit the inclined ground and will not be able to open fully. Chinese patent publication no. CN106948744A discloses a fan-shaped courtyard gate structurally comprising gate frames and a gate face plate. The gate frames are in groove shapes, a transmission motor is arranged on the lower portions of the gate frames, and a gate leaf fixing shaft with a bearing is arranged on the upper portions of the gate frames; the gate face plate is constituted by nine gate leaves in a fan-shaped mode; a bearing seat is arranged on the lower portion of each gate leaf; the gate leaf fixing shaft with the bearing is arranged on the upper portions behind the gate leaves, and an arc-shaped sliding groove in the upper portion in front of each gate leaf; each gate leaf is buckled with the corresponding arc-shaped sliding groove through the gate leaf fixing shaft between the gate leaves and pieces to form a fan shape. The gate leaves of CN106948744A have an arc-shaped sliding groove in the upper portion in front of each gate leaf to guide the movement of the gate leaf as the courtyard gate opens and closes. European patent no. EP2900892B1 discloses a gate or window/door frame consisting of one or two doors with mutually moving elements, said moving elements are hinged together for rotating around one or more axes perpendicular to the plane of the door itself, in such a way that, during the door closing movement, the moving elements move synchronized in a way that allows them to close packed on one another and that during the opening movement they spread in a radial pattern in a mode which is like the opening of a "hand fan", said moving elements opening out like a hand fan up to a predetermined mutual distance defined by a stop system integrated in the moving elements themselves. The stop system of EP2900892B1 is constituted by pins and slots formed in levers that support the moving elements which are rods. The movement of the moving elements are guided by pins and slots. As the pins and slots of the conventional solutions wear, the movement of the gate leaves, gate panels would become irregular. Other conventional solutions implement the use of scissor link mechanisms. Scissor link mechanisms cause injuries to when users place their finger, hand in between the scissor links. Furthermore, the scissor links do not have an aesthetically clean appearance. The present invention seeks to overcome the disadvantage of conventional solutions.
