Definitions
- the present invention relates to electrical gates fitted at least on the closure side of one anti-squashing edge, and refers, in particular, to a mobile feeder for this safety device.
- the conductors of the anti-squashing edge are connected to the motor power unit by a wire carried by a pulling chain, which is located in a casing fixed to the base of the gate.
- this method of electrical connection is not particularly safe and reliable due to thermal changes and the structure of the wire, which tends to break after a certain number of bends.
- the object of the present invention is to resolve the problems of the prior art and consequently propose a mobile feeder for anti-squashing edges that is much safer and more reliable even after a high number of moves of the gate, since it does not require the presence of mobile wires subjected to elevated wear and tear.
- a mobile feeder for anti-squashing edges on electric sliding gates comprising a section bar fixed to the base of the sliding gate and open at the bottom, a pair of thin conductive sheets set longitudinally in said profile connected to the conductors of the anti-squashing edges, and a sliding block fixed to the ground near a power unit controlling the motor, with one head inserted into the sliding section bar.
- the head of the sliding block carries sliding contacts, for example, small carbons, on which the thin conductive sheets slide, and to which the relative electrical conductors controlled by the power unit are connected.
- the feeder according to the invention comprises an upside down U shaped section bar 10 fixed to the base of a sliding gate 30, a pair of thin metal sheets 11 set longitudinally in said profile connected to the conductors of at least one anti-squashing edge 31 provided along the closure side of the gate, and a sliding block 12 fixed at the bottom on the floor near the motor apparatus 32 of the gate with one head 12' inserted into the sliding section bar.
- the sliding block has a pair of wiping contacts 13 on which the thin conductive sheets 11 slide, and to which the relative electrical conductors 33, which are controlled by an electronic power unit 34 controlling the motor, are connected.
- the power unit 34 draws the electrical supply from a supply device 35.
- the thin conductive sheets are set in relative longitudinal slots 14 in an upper horizontal wall of an internal section bar 15, which is made of plastic, rubber or some other insulating material, and inserted into an open lower part at the bottom of the section bar 10 fixed to the base of the gate, which can be made of aluminium, for example.
- the head 12' of the sliding block 12 is set in said internal section bar and protrudes from this at the bottom passing through a pair of flexible lips 16 that prevent external agents from penetrating the section bar.
- the sliding block is also made of insulating material and has vertical slots 17 on its opposite sides where the wiping contacts 13, galvanically separated, are inserted, for example in the form of rectangular section carbons. Each carbon is held in contact with a relative thin conductive sheet by a spring 13'.
- the head of the sliding block is also fitted at the top with rollers 18, on which the thin conductive sheets 11 slide, and at the side with balls 19 for sliding on the internal section bar.
- a particular clamp is provided; this is made up of a base plate 20 from which a C element 21 extends, where a complementary element 22 is free to slide vertically, and which is integral with an intermediate vertical plate 23 fixed to the lower part of the sliding block protruding from the section bar 10.
- any pressure on the anti-squashing edge 31 causes contact between the two conductors buried inside it, and therefore a lowering of the impedance of the circuit below a preset minimum threshold value, which is detected by the motor control power unit 34 by means of the thin sheets and the sliding contacts of the sliding block.
- any breaking of one of the conductors is detected by the power unit 34, again by means of the described feeder, as an increase in the impedance above a maximum preset threshold value and consequently as a condition for interrupting the motor supply.
- the proposed feeder is completely hidden and protected inside a section bar that is fixed to the base of the gate, it does not require the presence of flexible wires carried by pulling chains, since it makes use of the wiping contacts and therefore allows the objectives of safety, reliability, duration and compactness to be achieved.
