Abstract
Description
- The present invention relates to a panic bar or emergency handle.
- Panic bars are known comprising an elongated box-like body which is fixed to the side of the door wing that is directed toward the enclosed space and has an open U-shaped cross-section in order to accommodate the actuation bar or handle.
- Two parallel transmission levers are rigidly coupled to the bar and are articulated in a parallelogram-like configuration in the box-like body; one of said levers is operatively connected to the lock for closing the wing.
- Current panic bars have, at the opposite ends of the box-like body, respective caps for covering and protecting the opposite ends of the actuation bar. However, it has been observed that said caps have a structure which can compromise the safety of panic bars when they are actuated in an emergency situation. In such a situation, in fact, the bar, as a consequence of the pressure applied thereto, enters the box-like body, while the caps continue to protrude from its opposite ends.
- In an emergency situation, said ends can be dangerous elements on which clothing worn by people, or accessories such as handbags, umbrellas, etcetera, can catch.
- The aim of the present invention is to provide a panic bar which is conceived so that even in the pressed position of the actuation bar there are no protrusions capable of creating hindrances to the passage of people.
- Within this aim, an object of the present invention is to provide a panic bar which is structurally simple and safe and effective in operation.
- This aim and these and other objects are achieved with a panic bar comprising: an elongated box-like body, which is constituted by a profile having a substantially U-shaped cross-section; two levers, which are articulated in said box-like body in contrast with elastic return means and are connected like an articulated parallelogram, one of said levers being operatively connected to a closure lock; a bar, which is accommodated in said box-like body and is rigidly coupled to said pair of levers so as to be movable, parallel to itself, between a position in which it protrudes from said box-like body and a position in which it is substantially internal to said box-like body; characterized in that it comprises, at the opposite end with respect to the lock, a first bar closure element and a second box-like body closure element, said second element having such a height as to not protrude beyond the bar when said bar is inside said box-like body.
- Further features of the present invention will become better apparent from the following detailed description of an embodiment thereof, illustrated only by way of non-limitative example in the accompanying drawings, wherein:
- Figure 1 is a front view of a panic bar in an open condition;
- Figure 2 is a sectional view of the panic bar in an open condition, taken along the longitudinal line II-II of Figure 1;
- Figure 3 is a sectional view of the panic bar in a closed condition;
- Figure 4 is a sectional view, taken along the line IV-IV of Figure 2;

- Figure 6 is a sectional view of a lever; and
- Figure 7 is a plan view of the lever of Figure 6.
-
- With reference to the above-mentioned Figures, the panic bar according to the invention is generally designated by the reference numeral 1 and comprises an elongated box-
like body 2 being constituted by a profile which has a U-shaped cross-section with a bottom 3 (Figures 4 and 5) and twowalls 4 and 5 which rise at right angles from the bottom 3, so as to form alongitudinal cavity 6. - In the
walls 4 and 5, proximate to the internal angles formed with the bottom 3, twolongitudinal grooves plates - The
plate 9 has twowings pivot 13 for the articulation of alever 14 which is composed of twotriangular portions bridge 17. - The
triangular portions pivots articulation pivot 13, define the two arms of thelever 14. Aspring 20 is superimposed on thepivot 13, and its opposite ends engage below thebridge 17 and below alug 21 which is obtained by folding thewing 11. In this manner, thespring 20 can act so as to raise thelever 14 with respect to theplate 9. - A
block 22 is articulated on thepivot 19 and has atang 23 which is surmounted by atab 24. Agrub screw 25 is screwed through thetab 24 for fixing atubular element 26 which has a quadrangular cross-section on thetang 23. Theplate 9 protrudes out of the box-like body 2 with aportion 27 in which alug 28 is formed which is perpendicular to theplate 9. Asemicircular cap 30 is fixed to thelug 28 by way of ascrew 29 and, as will become apparent from Figures 3 and 4, is coupled to thewalls 4 and 5 of the box-like body 2. Thecap 30 has alip 31 which is folded inward and closes axially thecavity 6. - The
plate 9, once inserted in thegrooves cap 30 abuts against thewalls 4 and 5 of the box-like body 2, is fixed by means of a pair ofgrub screws plate 9 and engage against the bottom 3. - The
plate 10 also is locked on the bottom 3 of the box-like body 2, and aslider 34 is slidingly coupled thereon and is designed to activate a lock, generally designated by thereference numeral 35, which is fixed on theplate 10. - The
slider 34 is controlled by means which are fully identical to the means previously designated by thereference numerals 11 to 25 and supported on theplate 10. - Said means, for the sake of convenience in description, are designated by the same reference numerals increased by 100.
- The only evident difference relates to the
block 122, which is inverted by 180° with respect to theblock 22 so as to allow thetang 123 to enter, at one end, the end of thetube 26 that is opposite to the end engaged by thetang 23 and to act, at the other end, on aprotrusion 36 which is rigidly coupled to theslider 34. - The actuation of the
levers bar 37 which is inserted in thecavity 6. - The
bar 37 is composed of a profile which has a U-shaped cross-section with twowalls bottom 40 which constitutes the surface for pushing. Thewalls first pair 41 and asecond pair 42 of opposite grooves, which have a rectangular cross-section, and a third pair ofgrooves 43, which are intermediate to the pairs ofgrooves - The pairs of
grooves pivots pivots grooves 42 so as to ensure an ample rotation of thelevers levers pivots holes levers grooves 41. - The opposite ends of the
actuation bar 37 are closed byrespective closure elements - The
element 45 is hollow, has such a shape as to be accommodated in thecap 30, and comprises a semicylindricallower wall 47 which is shaped complementarily to the internal wall of the cap and aspherical wall 48 which forms a step 49 with it. - One end of the
bar 37 is inserted in aseat 50 of theelement 45 which is formed proximate to the front edge of theelement 45. - The
closure element 45 is fixed to the bar by way of two self-tappingscrews 51 which are driven through respective axial holes of theelement 45 and are screwed into the pair ofgrooves 43. - The
element 46 is constituted by a plug provided withinternal ridges 52 for forced-fit engagement in thegrooves element 46 is to be engaged has a chamfered shape in order to blend with thebox 53 that encloses themechanism 54 of thelock 35. - The
mechanism 54 is of a known type and comprises alever 55 which is pivoted in a rocker-like fashion on apivot 56 of the lock. Thelever 55 has afirst pivot 57 which, by means of aspring 58, is kept in abutment against aprotrusion 59 of theslider 34 and asecond pivot 60 which acts on alatch 61 which is articulated on anadditional pivot 62 of the lock in contrast with aspring 63. Thelatch 61 is provided with alocking lever 64 which prevents fraudulent retraction of the latch when it is engaged in the selvage 65. - As clearly shown by Figure 3, which illustrates in sectional view the panic bar in the closed condition, the
bar 37, by means of thesprings 20 and 121 that act on thelevers like body 2 and therefore in a position which closes thecavity 6. - In particular, the step 49 of the
element 45 is adjacent to thelip 31. - In an emergency situation, if one acts on the
bar 37, thelevers tube 26 that connects them, causing a movement of theblock 122 toward the lock. Theblock 122 acts on theprotrusion 36 of theslider 34, while theprotrusion 59, by acting on thelever 55, determines the retraction of thelatch 61 into thebox 31. - In the position for releasing the
latch 61, thebar 37 is fully accommodated within the box-like body 2. - A fundamental prerogative of the present invention is that when the
bar 37 is inside the box-like body 2, i.e., when it has been actuated in an emergency condition, the panic bar 1 does not have, at its opposite ends, protrusions or the like which can constitute regions on which the clothes of the people who are about to exit can catch. Differently from conventional panic bars, thecap 30 in fact does not lie above the level of the upper edge of the box-like body 2. At the same time, theelement 46 axially closes thebar 37 and its rounded shape does not offer dangerous protrusions. - One advantage of the above-described panic bar is that the
plates levers like body 2, so that theportions like body 2. The panic bar can be assembled by means of screws which are driven throughslots 66 of theportion 27 and similar slots of theportion 127. The distance between theportions like body 2 can lie transversely like a bridge on the central region of the wing and can allow to apply the panic bar to door wings constituted by glass panes. - In the practical embodiment of the invention, the shapes and the dimensions may vary according to requirements.
