Definitions

  • Object of the present invention is an antipanic pushbar. It is of the type which is fixable on one side of a door and connectable to a lock which can be manoeuvred from the other side by means of a normal handle or key.
  • the activating of the lock is performed by means of a mechanism which is able to transform a movement of a mobile body, with which the pushbar is equipped, into a rotation aimed at producing the opening movement of the lock.
  • the principal problem existing in the prior art, which the present invention resolves, is that of providing a single pushbar that is usable both with a right-side opening and with a left-side opening: that is, of providing a pushbar which can be applied either to the left or the right side of a door while producing the correct directional rotation in both cases for the rotation manoeuvre of the handle, situated on the opposite side of the door, to produce the opening of the lock.
  • the present invention as characterized in the claims which follow, provides a simple and effective solution to the above-described problem.
  • One advantage of the invention consists in its easy possibility of application to all types of locks normally coupled with antipanic pushbars.
  • 1 indicates a first embodiment of an antipanic pushbar which is provided with a base 4, arranged to be fixed to a side 20 of a door, and with a mobile body 5 mounted to the base 4 and able to move in normal direction with respect to said base 4.
  • the mobile body 5 is fixed to the base 4 by means of a mechanism, not illustrated in the figures, which is able to transform any reasonable movement of the mobile body 5 into an axial sliding of a bar 2 in the direction indicated by the arrow 11.
  • the bar 2 is guided in its sliding by a pivot 15, fixed to the base 4, which pivot 15 is coupled with an allowance internally to a longitudinal slot 16 bored into the bar 2.
  • the bar 2 has solid to it a pivot 3, which pivot 3 is arranged so as to interact with one end 8 of a right-angled command lever 6 which lever 6 is pivoted to the base 4 by means of a first fulcrum 7.
  • the lever 6 has a second end 9 arranged to interact on contact with a pivot 13 which is fixed to the end of a manoeuvring lever 10, in its turn pivoted on the base 4 by means of a hollow pivot 17.
  • the hollow pivot 17 has internally coaxially a square-section hole 18 into which can be inserted a manoeuvring organ 12 in the form of a square bar, arranged to be coupled with a corresponding square-section hole in the lock to which the pushbar 1 is to be coupled.
  • a second pivot 14 is arranged, with the aim of permitting of the pivoting of the same lever 6, which is also located with symmetrical disposition with respect to the said plane.
  • the lever 6 can be taken off the first fulcrum 7, turned about and pivoted on the pivot 14.
  • the command lever 6 is equipped with a generally symmetrical structure with respect to its own median plane, which is perpendicular to the rotation axis.
  • manoeuvring lever 10 can be arranged in a symmetrical position with respect to said longitudinal median plane, containing the rotation axis of the hollow pivot 17, in order to keep the reference position of the square-section hole 18 unaltered, so that a perfectly symmetrical mechanism is established with respect to the mechanism, represented in Fig. 2, constituted by the lever 6 and the manoeuvring lever 10.
  • FIG. 3 and 4 a second embodiment of the invention is illustrated which is different from the preceding one in substance by the fact that it envisages, contemporaneously mounted on the base 24 of a pushbar 21, two symmetrical mechanisms, activated by one bar 22.
  • the two said mechanisms are arranged symmetrically with respect to a longitudinal median plane perpendicular to the base 24 and containing the axis of the bar 22.
  • Each mechanism comprises a command lever 26 having a first end 28 in which a slot 35 is bored, arranged so that a pivot 23 fixed to the bar 22 couples internally to it.
  • Each command lever 26 is further equipped with a second end 29 arranged to come into contact with a pivot 33 of a manoeuvring lever 30, which manoeuvring lever 30 is pivoted by means of a hollow pivot 37 to the base 24.
  • the two levers 26 are pivoted to the base 24 by means of two pivots 27 and 28, which are located symmetrically with respect to the said median plane of symmetry.
  • the hollow pivot 37 is equipped with a hollow square-section sliding fit 38 arranged in order that internally to it a manoeuvring organ 32 can be coupled, which manoeuvring organ 32 comprises a usual-type square-section bar suitable for coupling with the corresponding hole with which the lock to be coupled with the pushbar 21 is equipped.
  • the two hollow pivots 37 present distinct parallel axes, symmetrically arranged with respect to the said longitudinal median plane.
  • a movement, induced by the mobile body 25 on the bar 22 in the direction indicated by the arrow 31, produces two equal rotations, but in opposite directions, of the two hollow pivots 37.
  • the manoeuvring organ 32 located in one of the two hollow pivots 37 the desired opening movement can thus be obtained.
