Definitions
- This invention refers to protection and safety device for automatic gates of a sliding type.
- Automatic sliding gates can actually turn into a source of serious problems for the user, due to the fact that because of the inherent configuration of their structures, they usually comprise moving parts fitted with edges very hazardous to the user's safety. This particularly applies where such structures are governed at a distance from fixed sites, by pushbuttons or remote controls, because the structure's motion cannot automatically be stopped at the instant of an impact by potential users or other objects against protruding portions of the mentioned structures, unless by manually interrupting the power feed to the systems at times subsequent to those actually needed.
- the protection and safety systems commonly employed for such structures are essentially based on the use of pneumatic protection ribs, positioned opposite the most dangerous edges and made of some flexible material, capable of sending out a signal by the contact of an electronic transmitter, whenever its internal pressure is varied in case of an accidental contact or impact.
- the structure's operation is consequently deactivated, bringing the same to a stop at the position attained.
- the protective rib is mounted, with the aid of a profiled steel section, on the advancing front surface of the gate itself, thus usually leaving a clearance just below the profiled steel section, so as to allow it be attached to the gate's structure; in this case, a clearance of usually 3-5 centimeters from the ground is left without the flexible material composing the protective rib, thus representing a serious hazard to a the user, especially to a child, at any instant and particularly at the time of first actuating the automatic gate.
- the purpose of this invention is therefore to produce a protection and safety device for automatic sliding gates, capable of eliminating the mentioned drawback.
- Another purpose of this invention is to indicate a protection and safety device for automatic sliding gates whose operation may in any situation turn out to be reliable, precise and correct, even in the case of accidental failures or malfunctions of the electrical control system.
- the device advantageously ensures the protection and safety required by any user present in the neighborhood of moving automatic sliding gates, even in case of a failure of the device to block the gate's advancing motion or of a breakdown of the mechanical device on the electrical assembly designed to break off the electric power supply to the drive motor.
- 22 generally indicates a protective rib for automatic sliding gates, comprising a profiled steel section 28, capable of being attached to an advancing front surface of the gate and a respective protection 27, shaped in form of a hood and made of rubber or any other flexible material, attached to the profiled section 28.
- the profiled section 28 of the rib 22 is usually mounted in front of the advancing surface of the automatic sliding gate.
- the rubber protection 27 reaches a certain height of the rib 22, and is in particular, as clearly shown in Figure 1, inserted into a terminal 71 typically raised 3-5 centimeters from the ground, so as to leave a certain clearance in which the profiled section 28 remains visible so as to enable its installation on the surface of the gate by a fastening screw 73 to be inserted in a passing hole 72; a guiding base 29 fitted into the protection 27 houses a steel cable 12 connected to a triggering mechanism of a known type, designed to shut off the electrical power supply to a mechanism actuating the sliding gate in case of an impact against the rib 22 on the part of a user.
- a protective shell 70 preferably made of rubber or at any rate of a flexible material, housing in its interior a leverage 10, essentially contoured in the shape of an L and mounted on a first fixed fulcrum pin 11 connected to a support 74 of the protective surface 27 and to a second mobile fulcrum pin 9 attached to the shell 70.
- the support 74 is attached to a sled 77 inserted inside the profiled section 28 opposite the hole 72 with the aid of a fulcrum pin 78, while an end 75 of the cable 12 is affixed to a terminal appendix 76 of the L-shaped part of the leverage 10 installed opposite the fulcrum pin 11.
- the electrical power supply to the drive motor of the sliding gate is instantly cut off by the action of the electrical power shut-off mechanism, so as to automatically arrest the motion in both a closing or opening phase, thus preventing further harm.
- the leverage 10 can advantageously be arranged at an inclined position, with respect to an imaginary vertical axis extending the longitudinal course of the rib 22; the size of the angle formed by the leverage 10 and the mentioned vertical axis is preferably taken in the range of 0 to 40 degrees, including its extremes.
- the device thus described makes it possible to prevent an accident in case of impacts occurring opposite the terminal portion of a traditional rib 22 for sliding gates, which usually exhibits, or at a clearance of about 3-5 centimeters above the ground, a rigid steel surface particularly dangerous to anyone moving around in the neighborhood; this portion is on the contrary covered by a flexible hood 70, so as in the first place dampen the possible impacts against objects or people and in the second place, as the protection 27, to make even this portion mobile, for the purpose of causing an instant stoppage of the sliding gate that happens to be in motion at the time of impact.
