Abstract
The invention relates to a safety edge for horizontally pivoted rolling gates actuated by a motor unit. It consists of a profile (11) made of rubber or other soft flexible material and having a base (14) for its application to a rolling date, and of two electrical conductors (15,16) extending longitudinally into the soft profile, parallel and normally separate from one another. The conductors move closer in the presence of a deforming thrust on said profile, to come into contact and enable an electrical circuit to send a signal for stopping the rolling gate motor unit.
Description
"II~'iPf~.t7VEl~ SAFETY EI'3GE FOR HORIZONTALLY PIVOTED
RdLLING GATES"
*x x* x* **
Field of a ~licatian 'I-he present tinding relates fo the field of hori2ontally pivoted rolling gates and similar automated devices, and in particular, it relates to a safety edge applicable as safety means to such closing systems.
Prier ,art 1o The apwlication of a so-called safety edge to horizontally pivoted rolling gates is already known. It consists of a rubber or soft material profile and a traction cable extending into the rubber profile and connecting to at least one micros~ritch, normally closed, inserted in the electrical circuit of the motor controlling the rolling gate. Since the edge is not stressed, the microswitch remains closed and the rolling gate is not enabled to operate regularly. If, on the other hand, during the rolling gate movement, usually white closing, the edge detects or interferes with a foreign element that hinders it motion, the stressed cable causes the microswitch to open, thus opening the electrical circuit of the motor unit and stopping the rolling gate 2o to l7re~;r~:n~: damages to people or things.
In such safety edge, the cable essentially has the function of actuating r"neans for the mechanical drive of a control to at least one microsvritch.
In a.nath'~r embodiment, a safety' ec~ae to be used on rolling gates uses laminations or crop ends of laminations s actuators, b~.~t always associated to current switches, Purpose and summary of the inyention Purpose of the present finding is that of implementing and providing an improved safety edge far motor-driven rolling gates embedding electrical conductor means for its entire length, and acting at the same time, in any part of the edge, as means for stripping the rolling gate motor unit when the edr~e comes into contar;i with an obstacle, or is in any case stressad byg a t:hru st.
.ar~uihec~ purpose of the invention is that of providing a high-efFciency safety edge for rolling gates, easy to realise and convenient to be installed without having to use special angle joins when the edge is arranged on more sides of a rolling gate.
Such purposes are obtained, according to the present finding, by a safety edge for motor-driven rolling gates consisting of a rubber profile, or made of another soft, flexible material, and of tuvo electrical conductors extending lanc~itudinally into said proFIL in parallel, normally separate from one another End movable closer to came vta contact in the presence of a defr~r-ming thrusfi on said profile and enable an electrical circuit to send a 2o signal for stoppinrg the rolling elate motor unit.

. Fic~e.ar~~ 2 sht~~pwrs a transversal spctic~n of the safety edge; and - Figure ~i s~;hematicaily shoves a horizontally pi~,~ated roiling gate ~;omplete ~,n~ith safety edge.
Detailpci description of the invention The safety edge shaven comprises a soft extruded profile 11 made of rubber or other flexible material, which longitudinally exhibits a i'irst seat 12 and a second seat 13, shaped as channels, parallel and open the one tov~ards thEa other. The first langitr;rdina! seat 12 is closer to the base 14 of io the profile than the second channel-shapad seat 13.
The first longitudinal seat 12 houses and holds a first electrical conductor 18, and the other longitudinal seat 13 houses a second electrical condu~;tor 16. The tvvo conductors 15, 16 extend for the entire length of profile 11, and the ~Frst of them preferably exhibits a round, half-round, elliptical or- similar section, whereas the second one preferably exhibits a t~lat se~,tion, such as in the shape of a tape, in any case flexible.
The t=ryst conductor 18 consists, for example, of a conductor braiding or mash 1' arrangers around an insulating core 18, and is exposed towards the sar:and flat conductor-18 uV~ith a. rounded portion of its surface.
2o Fo4- the realisation of the edge, the soft profile 11 can be extruded around one ur both conductors, embedding them. Or, conductors 18, 16 can be inserted into the respective seats 12, 13 of the soft pro~ie 11 after its extrusion.
In any case, i;onductor:~ 1 ~, 16 remain parallel and normally separate from ' 4 one another when the safety edge is at rest.
The edge thus structured is applied with its base 14 to the edges of a horizontally pivoted rolling gate 19, as shown in Fig. ~, for example, and conveniently inserted through the Conductors into the electrical circuit of the motor unit controlling the Bata.
As long a5 the edge is at rest, since it is not stressed by external thrusts, thc: conductors remain separate and the rolling gate operates normally.
If during the rolling gate motion, any part of the edge meets an obstacle or a hindrance, so as to be stressed and compressed by an external source, 1o the conductors close on one another, thus causing an immediate halt of the motor unit; and thereby of the rolling gate.
Given the shape and the association of the conductors, the safety edge trips in the presence of both orthogonal and inclined thrusts with respect to the profile base.
