Definitions

  • the present invention relates to a feathering frame for holding printed signs and/or messages, having improved monostability characteristics of its flag-like rest position.
  • these message bearing frames must extend perpendicularly to the face of the shelves, projecting into the passageway. For this reason they must preferably be mounted in a feathering manner so as not to constitute dangerous impediments to the free movement of people along the shelves.
  • the message bearing frames should automatically return to a rest position perfectly normal to the face of the shelf, following any accidental or intentional swinging (rotation) from such a functional (rest) position.
  • feathering frames to be used in large numbers in shops selling foodstuff must combine low cost, durability and washability properties.
  • This last requirement is dictated by hygienic considerations and should be satisfied by structures that can be washed and hygienized by immersion in detergent and/or bactericide solutions.
  • This requirement makes most of the known monostable pivoting mechanisms composed by springs, cams and metallic pins hardly suitable.
  • the entire structure should be of a non-corrodible, moldable plastic material for reducing also the manufacturing cost.
  • the known structures employ an inclined-axis hinge so that, when the frame is accidentally or intentionally swung on one side or the other from its natural rest position normal to the shelf's face, its centre of gravity describes an arc in space which brings it to rise to a higher level. By gravity, the hinged frame will tend to return to its flag-like rest position, which corresponds to the lowest level that may be assumed by its centre of gravity.
  • the special hinge of the invention relies on an inclination of the axis of rotation with regard to the vertical axis so as to cause a rising of the centre of gravity of the feathering frame pursuant a rotation of it in either direction from a flag-like rest position.
  • the female (tubular) part of the hinge which may be solidly connected to the feathering frame, bears on an inclined abutment surface of the sustaining arm or bracket, substantially free of any mechanical restraint upon a reciprocal movement of the two abutting surfaces.
  • the resting bottom surface of the female part of the hinge (rigidly connected to or integral with the feathering frame) is free to rotate while lifting one side or the other, off the inclined supporting surface through an evolving motion, thus establishing a point of abutment that may shift over the inclined surface of the supporting bracket by describing a certain arc on it, because essentially there isn't any restraint to the reciprocal movement between the two abutting surfaces.
  • the tubular (female) part of the hinge that is solidly connected to the feathering frame is engaged along an inclined axis of rotation that is incident on said inclined rest surface, by a pin, formed at the extremity of an arm extending from the sustaining bracket of the frame.
  • this pin-terminated arm has an arcuate form and possesses elastic memory characteristics sufficient to exert a certain elastically compressive force on the female part, the bottom end of which rests on the inclined surface of the sustaining bracket, at least pursuant a lifting of one side or the other of the abutting bottom surface of the female part of the hinge, off said inclined rest surface.
  • the rotation of the feathering frame induces an evolution/rotation of the bottom surface of the female part of the hinge on the inclined abutment surface of the sustaining bracket so as to determine an unstable (out-of-axis) abutment along a perimetral edge of the abutment surface of the female part of the hinge, on which the arm bearing the pin of the hinge exerts an elastic contrasting force.
  • the message holding frame may comprise a rectangular frame 1 of a plastic material, having a tubular (female) part 2 of a hinge that can be integrally formed with the rectangular frame 1 or otherwise solidly fastened to it.
  • the axis of the tubular hinge body 2 may have a certain angle of inclination ⁇ with regard to a vertical side of the rectangular frame 1.
  • the lower face 2' of the tubular part of the hinge 2 has a certain angle of inclination ⁇ with regard to a horizontal plane.
  • the two angles ⁇ and ⁇ may also be identical, but this is not a necessary condition and in particular the angle ⁇ may also be larger or smaller than the angle ⁇ . Commonly the angle ⁇ may be comprised between 10° and 15°, while the angle ⁇ may be comprised between 45° and 75°.
  • a sustaining bracket 3 which may be provided with clip means 4 for mounting on a magnetic block 5 or with suitable anchor plates that can be fastened to a shelf or to a wall.
  • the pin 6 of the hinge is carried by an arcuate arm 7 which extends from the support bracket 3.
  • the inclined axis of the pin 6 is incident on a rest surface 8, which may be substantially flat and inclined by an angle ⁇ with regard to a horizontal plane.
  • the mounting of the feathering frame is carried out by forcibly shifting the arm 7 sufficiently to permit to slip the tubular part 2 of the hinge over the pin 6.
  • the arcuate arm 7 has a certain elastic memory and may be able to exert a certain contrasting force on the tubular part 2 of the hinge to keep the inclined terminal face 2' of the tubular part 2 of the hinge abutting flat on the inclined surface 8 of the supporting bracket 3 also when the frame 1 is in a rest position.
  • the hinged frame 1 When the hinged frame 1 is rotated in either side off its stable rest position (flag-like position), beside lifting its centre of gravity because of the inclination of the pivoting axis of the hinge with regard to the vertical axis, the lower face 2' of the tubular part 2 undergoes an evolving movement by lifting one side off abutment with the rest surface 8 thus bearing on the inclined rest surface 8 of the support arm 3 with one point of its elliptical perimeter in opposition to a contrasting elastic force exerted by the arcuate arm 7 of the pin 6 of the hinge.
  • the elastic force exerted by the arm 7 determines a moment-of-force or torque about the point of abutment between the two surfaces which forces the hinged frame 1 to return to a rest position so as to re-establish a stable flat abutment of the lower face 2' of the tubular part 2 of the hinge on the inclined surface 8 of the support bracket 3 (i.e. nullification of the moment-of-force).
  • the device of the invention combines with the moment-of-force caused by the inclination of the pivoting axis of the hinge, and therefore by the lifting upon rotation of the centre of gravity of the hinged frame, a moment-of-force determined by the contrasting elastic force exerted by the arm 7 about the out-of-axis abutment point between a bottom edge of the tubular part 2 of the hinge and the inclined surface 8 of the supporting bracket.
  • the second moment-of-force that is determined by the elastic force exerted by the arcuate arm 7 retains an "arm" lenght that is perfectly effective as long as the returning of the abutting surfaces 2' and 8 to a mutually parallel position is not complete. This ensures a characteristic of substantial monostability of the rest position and therefore the return to it after any swinging of the hinged frame 1 off its rest position (flag-like position of the frame).
