Definitions

  • This invention relates to a stop device for gates, doors, automatic doors and the like, characterised in that it is retractable and therefore does not present the drawbacks due to the presence of the traditional stop device that projects from the floor.
  • a stop device In the case of side-hinged gates and doors, especially automatic gates, a stop device must be installed to determine the closing or maximum opening position of the gate.
  • Stop devices are used to stop the gate movement and shut down the motor when the gate reaches the "fully open” or “fully closed” position.
  • the "fully open" position is determined by stop means positioned on the floor, consisting of bases, teeth, tubular parts or feet which are secured to the floor in various ways to constitute a fixed rebate for the gate.
  • a stop device that projects from the floor is often installed in correspondence with the central area of the gate in the closing position.
  • stop means relates to the fact that their position, projecting from the ground, can represent an obstacle and a serious danger for pedestrians, who may trip over it, and for vehicles in transit which, especially in the case of sloping or raised ground, may strike it with the lower part of the chassis and damage the vehicle or its mechanical parts.
  • the invention solves these drawbacks by using a mechanical stop device that can be attached to the door or gate and collaborates with a matching seating in the floor.
  • This seating is made in such a way that it is normally closed, so as to eliminate any possibility of accidents to persons or vehicles, and opens when intercepted by the stop device attached to the door or gate when it reaches the seating, and therefore its maximum opening position.
  • no. 21 indicates a gate, door or the like fitted with the stop device in accordance with the invention.
  • the device in accordance with the invention comprises a support structure 22 constituted by a plate 23 attached to the gate, for example by welding, screwing and the like, which said plate is integral with a pair of parallel wings 24 that support a body 25 fitted eccentrically to a shaft 26 attached to wings 24 in such a way that body 25 tends to rotate downwards due to the effect of gravity.
  • wings 24 From the inside, wings 24 present two projecting parts whose upper surface 28 is inclined.
  • the amplitude of rotation of body 25 around shaft 26 is defined by the projecting extremities of a plate 29, welded or otherwise attached to body 25, which engage with inclined surfaces 28 of the said projecting parts, as shown in figure 2.
  • Cavities 30 in the ground in correspondence with the maximum opening and/or closing position of the gate are designed to receive body 25, which penetrates into the cavity and engages with the wall of the cavity, which thus acts as a door stop.
  • the cavity has a body 30 of any suitable shape, for example a cylindrical body, closed at the top by a pair of opposing doors 31 and 31' which are hinged to two substantially horizontal shafts 32 and 32'.
  • Doors 31 and 31' are connected via a cable 33 or other known system to a counterweight 34 which, in the case illustrated in the figure, is ringshaped, and slides inside cavity 30.
  • counterweight 34 tends to keep doors 31 and 31' in the position shown in figure 4, where they close the cavity, preventing the entry of dirt and the like.
  • the device operates as follows.
  • body 25 rests on the ground via wheel 27 and can move freely.
  • body 25 with wheel 27 is positioned above cavity 30.
  • body 25 then overcomes the thrust exerted by counterweight 34 via cables 33, and opens doors 31. Body 25 then enters the cavity, as shown in figures 2 and 5.
  • body 25 engages with the wall of the cavity, which thus acts as the door stop and prevents further advance of body 25, consequently stopping the travel of the gate.
  • the stop device in question is specially designed and manufactured to meet safety criteria and also to be more compact, thus producing an end product of high quality and ergonomic design.
  • the solution offered by this invention also eliminates the traditional floor-mounted door stops consisting of bases and the like, which constitute a potentially dangerous obstacle, thus solving all the problems they present.
  • seating 2 which contains the stop devices could form part of the structure of a gate or door, as will be illustrated with reference to figures 8 and 9.
  • a box-shaped container 2 fitted to the bottom of gate 21 in correspondence with the free edge opposite the edge to which the hinges are fitted, forms a seating designed to receive door stop 3 which is normally kept pushed outwards, i.e. downwards, and designed to fit into a corresponding seating 4 in floor 5.
  • door stop 3 consists of a mobile body, hinged to a fulcrum 6 and fitted with a wheel 7 at the bottom, which projects downwards from the gate and is normally maintained in this position, i.e. pushed towards the ground, by elastic means such as a spring 8 or the like, which is hooked onto the wall of seating 2.
  • Door stop 3 can rotate around fulcrum 6 in such a way as to move from an upward recessed position in which it retracts completely inside the gate, with the wheel resting on the ground (fig. 8), to an operating position in which it projects from the gate and is inserted into seating 4 in the ground (fig. 7).
  • Seating 4 is located in a position on the floor corresponding to the position of the free edge of the gate when the gate is in the maximum opening or closing position.
  • the maximum outward extension of door stop 3 is determined when tooth 12, fitted to the top of door stop 3, comes to rest against a fixed rebate 13 in seating 2 (fig. 7) or in the door structure (fig. 8).
  • This stop device for side-hinged gates and the like operates as follows.
  • the stop device When the gate is in a position other than the maximum opening or closing position, the stop device is in the condition shown in figure 8, with wheel 7 resting on the ground and its mobile support 3 fully retracted into the gate.
  • door stop 3 which could be made to slide instead of rotate, or fitted to a vertically sliding shaft 14 which counteracts a spring 15, as shown in figure 9, or represented by variations in the design of hatch 9 which, as shown in figure 10, could be made in two parts with an accordion fold, or made with other parts more suitable for the same purpose.
  • a rotating support 16 is hinged to the gate structure in proximity to a corner and can rotate through an angle which, in the case illustrated, is approximately 90 degrees, between two extreme positions in which a pair of adjacent sides 17 and 18 thereof engage with the edge of a fixed rebate 19.
  • a spring 20 tends to force support 16 into the position illustrated in figure 12, in which it projects from the gate, is inserted into seating 4, and engages with the wall of the said seating.
  • FIG. 13 A further version of the device, designed to act as stop device in both the closing and opening positions of the gate, is illustrated in figure 13.
  • box-shaped container 2 contains two supports 3 and 3' which are hinged to opposite sides of a support plate P.
  • Supports 3 correspond substantially to the supports shown in figures 1 and 2, but are fitted symmetrically in relation to their common axis of rotation.
  • the two supports can stop the movement of the gate in both directions.
  • a stop device for the opening of gates and the like is thus obtained without parts projecting from the ground, and the risks and drawbacks they present.
  • the arched contour of the lower edge of the two supports helps them to slide against the edge of seating 4 when the gate movement is reversed.
