DETAILED DESCRIPTION

(7) This time, using the labeled pictures will proceed to the detailed description.

(8) The present specification, as mentioned above, discloses a telescopic mechanism used in conjunction with an electric motor and system of gears to allow compression and extension movements of a sliding structure, consisting of a plurality of panels that could overlap on each other through a belt and pulley system so as to configure a gateway.

(9) The door comprises an intelligent control board (10) which receives commands for opening and closing the door by applying telescoping control.

(10) Subsequently drives the motor (20) to rotate in order to linearly move the belt (31). The belt (31) has the ends fixed to the brake (37) which is integral with the chassis (30) and causes the movement of the wheels (46) and (47) are united and fixed to the panel A (40), which is movable, which is fixed to a system of linear guides (32). These wheels (46; 47) are rotated by the belt (31) and the course is maximized to the external dimension of the entire system. Static pulleys (35, 36) do not rotate due to the belt (31) because it is fixed to the chassis (30).

(11) Simultaneously, the panel A (40) is integral with Panel B (50) via a lever system (43) and arms (42; 45) establishing a relationship of movement. Panel A (40) to extend, moves the axis of rotation (44) of the lever (43) and transmits this movement to the panel B (50) through the arms (42, 44) supported in rotary union (41). The Panel A (40) is connected to Panel B (50) via linear guides (32).

(12) The motion transmission system implemented in this solution allows to maximize the travel due to the vertical offset of the wheels (46; 47) and relative to the pulleys (33; 34) are in the chassis (30) fixed. This detail provides the system with an efficiency greater than other systems since it maximizes the movement of the Panel A (40) with respect to Panel B (50) with a dimensional gain similar to the diameter of the pulleys (33; 34). Being a telescoping, this gain is doubled and gives the engine an efficiency that is distinguished from all existing products in a market where size is a factor in the decision maker equipment to be selected.

(13) Detail passage movement of the chassis (30) for Panel A (40):

(14) FIGS. 3 to 5 illustrate three states in order to visualize the motion sequence, they are collected, mid-term and extended.

(15) In the retracted position the panel (40) is in the initial position, which is reached when the pulley (34) and the wheel (46) have their centers coincide in the vertical plane.

(16) In the middle of the route position when the motor (20) is rotating through its pulley transmit movement to the belt (31) which is secured to the brake (37). This movement of the motor (20) pulley exerts a traction force on the belt (31) which in turn pulls the wheel (47) which is attached to Panel A (40). The wheel (46) which is located on the same Panel A (40) wheel and then receives the coming belt (31) pulley of the motor (20).

(17) The belt (31) is in a closed and bounded peripherally by pulleys (33; 34; 35; 36), the wheels (46; 47), the brake (37) and the motor pulley (20) by rotating causes a linear movement in Panel A (40).

(18) In the extended position Panel A (40) is the final position of the course. The final position is achieved when the pulley (33) and the wheel (47) have their centers coincide in the vertical plane.
