Detailed Description

Fig. 1-15 illustrate one embodiment of a panic lever device 100 of the present invention.

The emergency lever device 100 of the present invention includes: a first support assembly 1 and a second support assembly 1' configured for securing to the door 101; a first arm 2 pivotally coupled at a first end to the first bearing assembly 1 by means of a first operating shaft 81; a second arm 2 'pivotally coupled at a first end to the second support assembly 1' by means of a second operating shaft 81; and a tie rod 3 coupled to the second ends of the first and second arms 2, 2 ' such that when the tie rod 3 is pushed, the tie rod 3, the first and second arms 2, 2 ' pivot relative to the support assembly 1, 1 '.

The support assembly 1, 1 'comprises a rotation shaft 21 comprising a housing 22 for the operating shaft 81, the rotation shaft 21 being configured for rotation together with the operating shaft 81 and the respective arm 2, 2' of the jerk device 100.

The first arm 2 and the second arm 2 ' are selected from a plurality of pairs of arms 2, 2 ' configured for having different inclinations in the panic lever device 100 with respect to the front surface 104 of the door 101, in a standby condition of the panic lever device 100, in which the lever 3 is not pushed, the different inclinations being obtained by varying the angular orientation of the operating shaft 81 with respect to the arms 2, 2 '.

Fig. 8A and 8B show the arm 2 and the arm 2 ' of the first pair of arms 2, 2 ' of this embodiment of the emergency lever device 100, wherein the operating shaft 81 is coupled to the arm 2 and the arm 2 ' in a first angular orientation. In the standby state, after coupling the arm 2 to the bearing assembly 1, the arm 2 has an inclination angle equal to the angle α with respect to the front surface 104 of the door 101, as shown in fig. 7A. In the same way, after coupling the arm 2 ' to the support assembly 1 ', in the standby condition, the arm 2 ' has an inclination with respect to the front surface 104 of the door 101 also equal to the angle α, i.e. once the arms 2, 2 ' of the first pair are coupled to the respective support assemblies 1, 1 ', they are both positioned at the same inclination angle α with respect to the front surface of the door 101.

Fig. 9A and 9B show arm 2 and arm 2 ' of the second pair of arms 2, 2 ' of the emergency lever device 100, wherein the operating shaft 81 is coupled to the arm 2 and arm 2 ' at a second angular orientation. After coupling the arm 2 to the support assembly 1, in the standby state, the arm 2 has an inclination equal to the angle β with respect to the front surface 104 of the door 101, as shown in fig. 7B. In the same way, after coupling the arm 2 ' to the support assembly 1 ', in the standby condition, the arm 2 ' has an inclination with respect to the front surface 104 of the door 101 also equal to the angle β. Thus, after changing the angular orientation of the operating shaft 81 with respect to the arms 2, 2 ' of the first pair of arms 2, 2 ' to the second pair of arms 2, 2 ', it is achieved that the second pair of arms 2, 2 ' is positioned at an inclination different from the inclination at which the first pair of arms 2, 2 ' is positioned with respect to the front surface 104 of the door 101. In the same way, the emergency lever device 100 of this embodiment can be used with other pairs of arms 2, 2 ', wherein different inclinations will be obtained when the angular orientation of the operating shaft 81 is varied with respect to the arms 2, 2'.

When the emergency lever device 100 is installed, the arm 2 of each pair of arms 2, 2 'is coupled to the support assembly 1 from one end of the rotation shaft 21, and the arm 2' of the pair of arms 2, 2 'is coupled to the support assembly 1' from the other end of the rotation shaft 21. This is why the angular orientation of the operating shaft 81 with respect to the arm 2 and the angular orientation of the operating shaft 81 with respect to the arm 2 'must be such that the arm 2 and the arm 2' are symmetrical with respect to a plane of symmetry which, when the two arms 2, 2 'are viewed in side view, lies between the two arms 2, 2' and is at the same distance therefrom, as shown in fig. 8A and 8B, or as shown in fig. 9A and 9B.

The fact that the same panic lever device 100 can be used with different pairs of arms 2, 2 ' makes it possible that the same panic lever device 100 can be used with different locks present on the market, so that the pair of arms 2, 2 ' can be chosen so that they have the right length and inclination with respect to the front surface 104 of the door 101, depending on the characteristics of the lock used with the panic lever device 100 and the force that needs to be exerted on the pair of arms 2, 2 ' to open it.

In the panic lever device 100 of this embodiment, the first support assembly 1 will act on the lock mounted on the first or second side of the door 101, while the second support assembly 1' will not act on any lock. Thus, in the emergency lever device 100 of this embodiment, the first bearing assembly 1 acting on the lock comprises a support element 11 comprising a base plate 12 configured for fixing to the front surface 104 of the door 101, a first side plate 13 attached to the base plate 12 on the side of the first side plate 13, and a second side plate 13' attached to the base plate 12 on the opposite side facing the first side plate 13, as shown in fig. 11. Each side plate 13, 13 ' comprises a hole 14, 14 ', the two holes 14, 14 ' facing each other, and a rotation shaft 21 is received in the holes 14, 14 ' of the side plates 13, 13 '. The first bearing assembly 1 includes at least one pushing member 41 coupled to the rotary shaft 21 and configured to rotate together with the rotary shaft 21, the pushing member 41 including a protrusion 42, as shown in fig. 10. The first bearing assembly 1 comprises a lock actuating member 31 coupled to the base plate 12 and configured for rotating about an axis perpendicular to the base plate 12 and acting on the lock, the actuating member 31 comprising a protrusion 32, said protrusion 32 being configured for being pushed by a protrusion 42 of a pushing member 41, thereby causing rotation of said actuating member. The pushing element 41 is configured for delimiting the angular travel of the panic lever device 3 in cooperation with the standby position stop 121 and the end-of-travel stop 122. The second support assembly 1' which does not act on the lock is identical to the first support assembly 1 which acts on the lock, and it does not have the lock actuating member 31.

Fig. 12 shows the lock actuation element 31 of this embodiment of the panic lever device 100. The lock actuation element comprises a protrusion 32 which, in this embodiment, extends radially and outwardly with respect to the shaft on which the lock actuation element 31 rotates.

The rotation shaft 21 is configured for rotation together with the arms 2, 2 'of the emergency lever device 100, such that when the lever 3 is pushed, the arms 2, 2' pivot with respect to the bearing assemblies 1, 1 ', thereby rotating the rotation shaft 21 coupled with said arms 2, 2'. The rotating shaft 21 is coupled to the pushing element 41. Thus, when the pull rod 3 is pushed, the pushing element 41 rotates together with the rotation shaft 21, causing the lock actuating element 31 to rotate. In this embodiment, the lock actuation element 31 has a square bore in which a shaft is coupled for rotation with the lock actuation element 31. The shaft is coupled to a lock arranged in the door 101 such that upon rotation of the lock actuation element 31 the shaft will act on the lock such that the lock will allow the door to be opened.

As shown in fig. 3, a sleeve 33 is provided between the lock actuation element 31 and the base plate 12 to which said lock actuation element 31 is coupled, such that by means of the use of the sleeve 33, a direct contact between the lock actuation element 31 and the base plate 12 is prevented.

As shown in fig. 6, the base plate 12 includes at least one side projection 18 on one side of the base plate 12, and the side projection 18 includes a standby position stopper 121 and an end-of-travel stopper 122. As shown in fig. 10, the pushing element 41 comprises a stand-by projection 411 which cooperates with the stand-by position stop 121 in the stand-by state of the panic lever device 100. The pushing element 41 comprises an end-of-travel projection 441 which cooperates with the end-of-travel stop 122 when the user pushes the tie rod 3 and reaches the end of its angular travel.

In the emergency lever device 100 of this embodiment, the support assembly 1, 1' comprises at least one additional removable end-of-travel stop 123 defining a travel smaller than the end-of-travel stop 122, the end-of-travel stop 122 being a fixed stop. This allows the lever 3 of the panic lever device 100 to have two different angular strokes, which enables the panic lever device to be used with the locks that are available on the market, in which the lever 3 will have a given angular stroke, and with locks in which the lever 3 will have different angular strokes. Thus, when the additional detachable end-of-travel stop 123 is removed from the emergency pull rod arrangement 100, the pull rod 3 assumes a certain angular travel, and when said additional detachable end-of-travel stop 123 is located in the emergency pull rod arrangement 100, the pull rod 3 assumes a smaller angular travel.

In the emergency lever device 100 of this embodiment, the additional removable end-of-travel stop 123 is a shaft 91 configured for being received in the facing holes 17, 17 'arranged in the side plates 13, 13'. Fig. 11 shows the shaft 91 of this embodiment, which is received in the holes 17, 17 'of the side plates 13, 13'. The pushing element 41 comprises an additional end-of-travel protrusion 431 which cooperates with an additional removable end-of-travel stop 123 when the user pushes the pull rod 3, as shown in fig. 8.

In the emergency draw bar device 100 of this embodiment, the additional removable end-of-travel stop 123 comprises a recess 92, and the support assembly 1, 1' comprises a resilient projection 73 between the two side plates, which is configured to be received in said recess 92 and fix the axial position of said additional removable end-of-travel stop 123.

In the panic lever device 100 of this embodiment, the support assembly 1, 1 'comprises a guide element 71 positioned on the base plate 12 and coupled to the side plates 13, 13', the guide element 71 comprising an elastic projection 73. The guide element 71 is preferably made of a plastic material. In the case of acting on the first bearing assembly 1 of the lock, the guide element 71 is positioned on the base plate 12 and the lock actuating element 31, the lock actuating element 31 being coupled to the guide element 71.

The guide element 71 of this embodiment of the emergency lever device 100 comprises a plurality of flanges 72 and each of the side plates 13, 13 'comprises at least two holes 16, such that when each flange 72 is introduced into its respective hole 16, the guide element 71 is coupled to the side plate 13, 13'. The guide element 71 of this embodiment can be seen in fig. 3, wherein the guide element 71 comprises four flanges 72, two flanges 72 on one side of the guide element 72 and two further flanges 72 on the other side. The side plates 13, 13 'of this embodiment can be seen in fig. 12, wherein the first side plate 13 comprises two holes 16 and the second side plate 13' also comprises two holes 16, so that the two flanges of one side of the guide element 72 are introduced into the two holes 16 of the first side plate 13 and the two flanges of the other side of the guide element 71 are introduced into the two holes 16 of the second side plate 13 ', the guide element 71 thus being coupled to the side plates 13, 13'.

In the panic lever device of this embodiment, the operation shaft 81 includes a fixing member 82 and an urging device 83 configured to urge the fixing member 82 radially out of the operation shaft 81, and the rotary shaft 21 includes a hole 23 in a radial direction on the periphery of the housing 22, the fixing member 82 being configured to be received in the hole 23 and fix the operation shaft 81 to the rotary shaft 21 when the operation shaft 81 is introduced into the housing 22. The housing 22 comprises a contour and the fixing element 82 at least partially protrudes from the contour of the operating shaft 81 when the operating shaft 81 is not introduced into the housing 22. The fixing element 82 is configured such that it is retracted and housed inside the operating shaft 81 when it abuts against the profile of the housing 22 after the operating shaft 81 is introduced into the housing 22. For this purpose, the portion of the fixing element 82 projecting from the operating shaft 81 when this operating shaft is not introduced into the housing 22 preferably has a curved or planar upward surface which allows the fixing element 82 to be retracted after abutment with the profile of the housing 22 during the introduction of the operating shaft 81 into the housing 22. In another embodiment, the portion of the fixing element 82 projecting from the operating shaft 81 may have another shape that allows the fixing element 82 to retract after abutment with the profile of the housing 22 during introduction of the operating shaft 81 into the housing 22. When the fixing member 82 faces the hole 23 during introduction of the operating shaft 81 into the housing 22, the pushing device 83 pushes the fixing member 82 so that the fixing member 82 protrudes again at least partially from the contour of the operating shaft 81, the portion of the fixing member 82 protruding from the operating shaft 81 being received in the hole 23, thereby fixing the operating shaft 81 to the rotating shaft 21. Fig. 2 shows an embodiment of the first arm 2 of the panic lever device 100, wherein the operating shaft 81 is fixed to said arm 2. In another embodiment, the operating shaft 81 can be fixed to the arm 2 by means of screws, by means of an adhesive, by means of welding or by using other fixing means known in the art.

The emergency pull rod arrangement 100 of the invention shown in fig. 1 facilitates its mounting on the door 101, since the arms do not need to be screwed to the corresponding bearing assembly 1, 1' to be fixed, but it is sufficient to insert the arms until the fixing element 82 is fixed in the hole 23 of the housing 22 of the rotary shaft 21.

In this embodiment of the emergency lever device 100, the housing of the rotary shaft 21 and the operating shaft 81 have a cross section configured such that the operating shaft 81 can be introduced into the housing 22 at a single position. In view of the fact that there is only one possible position in which the operating shaft 81 can be introduced into the housing 22, this thereby prevents a person responsible for fixing the arms 2, 2 ' to the bearing assembly 1, 1 ' from fixing the arms 2, 2 ' incorrectly.

In this embodiment of the emergency lever device 100, the housing 22 of the rotary shaft 21 and the operating shaft 81 have a regular polygon in cross section with a bevel 84 in one of the vertices of the polygon, as shown in fig. 1 and 4.

In this embodiment of the emergency lever device 100, the rotary shaft 21 comprises an additional hole 23 'in the radial direction on the periphery of the housing 22, which is symmetrical to the hole 23 with respect to a plane perpendicular to the longitudinal axis of the rotary shaft 21 at the midpoint of said rotary shaft 21, so that the fixing element 82 is accommodated in the hole 23 when the operating shaft 81 is introduced into the rotary shaft 21 from the first end of the rotary shaft 21, and the fixing element 82 is accommodated in the additional hole 23' when the operating shaft 81 is introduced into the rotary shaft 21 from the second end of the rotary shaft 21. The arm 2, 2 'may be introduced into the first end of the rotation shaft 21 or into the second end of the rotation shaft 21, which enables to fix the bearing assembly 1, 1' on the first side or the second side of the door 101. Furthermore, the emergency pull rod arrangement 100 of this embodiment prevents a person responsible for fixing the arm 2, 2 ' to the support assembly 1, 1 ' from attempting to fix the arm 2, 2 ' incorrectly, i.e. to fix the arm 2, 2 ' in a support assembly 1, 1 ' not corresponding to this arm. Since the operating shaft 81 is a regular polygon in cross section with a bevel 84 in one of the vertices of the polygon, the arm 2 is fixed at an angle of inclination that looks incorrect at a glance in the case of fixing the arm 2 to the bearing assembly 1', i.e. to an incorrect bearing assembly. Fig. 5 shows a sectional view of this embodiment of the emergency lever device 100, wherein the arm 2 has been introduced into the first end of the rotary shaft 21 and the fixing element 82 of the operating shaft 81 is received in the bore 23.

As shown in fig. 5, in this embodiment of the panic lever device 100, the fixing element 82 is a pin.

As shown in fig. 5, in this embodiment of the panic lever device 100, the pushing device 83 is a spring.

In this embodiment of the emergency lever device 100, the hole 23 in the radial direction on the periphery of the housing 22 is a through hole. As can be observed in fig. 5, in this embodiment, the hole 23 communicates the housing 22 of the rotating shaft 21 with the outer surface of said rotating shaft 21.

In this embodiment of the panic lever device 100, if in the standby state the projection 32 of the lock actuation element 31 is arranged in the first angular position, the projection 32 is pushed by the projection 42 of the pushing element 41, the lock actuation element 31 is rotated in one direction, and if the projection 32 is arranged in the second angular position, the projection is pushed by the projection 42 'of the additional pushing element 41', the lock actuation element 31 is rotated in the opposite direction.

In the standby state, the lock actuation element 31 of this embodiment of the panic lever device 100 comprises a first standby position in which the projection 32 of the lock actuation element 31 is arranged in the first angular position and a second standby position in which the projection 32 of the lock actuation element 31 is arranged in the second angular position. When the lock actuation member 31 is arranged in the first standby position and the pull rod 3 is pushed, the pushing member 41 pushes the protrusion 32 of the lock actuation member 31, rotating the lock actuation member 31 in one direction, and when the lock actuation member 31 is arranged in the second standby position and the pull rod 3 is pushed, the additional pushing member 41' pushes the protrusion 32 of the lock actuation member 31, rotating the lock actuation member 31 in the opposite direction.

In this embodiment of the panic lever device 100, the projection 32 comprises a first contact surface 321 and a second contact surface 322, so that when the lock actuation element 31 is in the first, inactive position and the lever 3 is pushed, the pushing element 41 pushes the projection 32, bringing it into contact with the first contact surface 321. In the same way, when the lock actuation member 31 is in the second standby position and the pull rod 3 is pushed, the additional pushing member 41' pushes the projection 32, bringing it into contact with the second contact surface 322. The first and second standby positions of the lock actuation element 31 are positions of the lock actuation element 31 where the lever 3 of the panic lever device 100 is not pushed.

Fig. 13 shows a part of the first bearing assembly 1 of this embodiment of the emergency lever device 100, with the lock actuating member 31 in the first, inactive position. Fig. 10 also shows this embodiment, in which the lock actuating element 31 is in the first, inactive position, so that when the pull rod 3 is pushed, the pushing element 41 pushes the protrusion 32 of the lock actuating element 31, rotating the lock actuating element 31 in one direction, for which purpose the pushing element 41 will be in contact with the first contact surface 321.

The first bearing assembly 1 of this embodiment is configured for being interchangeably arranged on the first side or the second side of the door 101 such that when the lock is arranged on the first side of the door 101, the lock actuating member 31 of the first bearing assembly 1 acting on the lock will be arranged in the first, inactive position shown in fig. 10 such that when the pull rod 3 is pushed, the pushing member 41 will push the protrusion 32 of the lock actuating member into contact with the contact surface 321, thereby rotating the lock actuating member 31 in one direction, in a clockwise direction, thereby acting on the lock and thus opening the door 101. When the lock is arranged on the second side of the door 101, the lock actuating member 31 acting on the first bearing assembly 1 of the lock will be arranged in the second standby position, such that when the pull rod 3 is pushed, the additional pushing member 41' will push the protrusion 32 of the lock actuating member 31 into contact with the contact surface 322, thereby rotating the lock actuating member 31 in the opposite direction, i.e. in the counter clockwise direction, thereby acting on the lock and thus opening the door 101.

In this embodiment of the panic lever device 100, the pushing element 41 and the additional pushing element 41' are coupled to the rotating shaft 21 and are configured for directly pushing the protrusion 32 of the lock actuation element 31. The rotating shaft 21 comprises four protrusions at each end thereof, and the pushing element 41 and the additional pushing element 41 'each comprise a hole in which said protrusions are coupled, and after being riveted, the rotating shaft 21 is allowed to be fixed at one end to the pushing element 41 and at the other end to the additional pushing element 41'.

In this embodiment, the projection 42 comprises a contact surface 421 such that when the lock actuating member 31 is in the first, inactive position and the pull rod 3 is pushed, the projection 42 of the pushing member 41 acting on the first bearing assembly 1 of the lock directly pushes the projection 32 of the lock actuating member 31, for which purpose the contact surface 421 of the projection 42 of the pushing member 41 pushes the first contact surface 321 of the lock actuating member 31. In the same way, the projection 42 ' comprises a contact surface 421 ' so that when the lock actuating member 31 is in the second standby position and the pull rod 3 is pushed, the projection 42 ' of the additional pushing member 41 ' acting on the first bearing assembly 1 of the lock directly pushes the projection 32 of the lock actuating member 31, for which purpose the contact surface 421 ' of the projection 42 ' of the additional pushing member 41 ' pushes the second contact surface 322 of the lock actuating member 31.

The support assemblies 1, 1' of this embodiment of the panic lever device 100 are configured for positioning in the same orientation, regardless of whether they are arranged on the first or on the second side of the door 101. Thus, the person responsible for fixing the bearing assembly 1, 1 ' to the door 101 does not have to consider whether the bearing assembly 1, 1 ' is to be fixed on the first side or on the second side of the door 101, considering that the bearing assembly 1, 1 ' does not need to rotate or change its position according to the side of the door 101 in which it is to be fixed.

As shown in fig. 13, in the first bearing assembly 1 of this embodiment, the lock actuating member 31 is arranged centrally between the two side plates 13, 13 ', the projection 32 of said lock actuating member 31 being arranged close to the first side plate 13 when said lock actuating member 31 is arranged in the first inactive position, said projection 32 being arranged close to the second side plate 13' when said lock actuating member 31 is arranged in the second inactive position, the pushing member 41 being arranged close to the first side plate 13 and the additional pushing member 41 'being arranged close to the second side plate 13'. Thus, when the person responsible for securing the first bearing assembly 1 to the door 101 secures the first bearing assembly 1 on the first side of the door 101, the person must take into account that the protrusion 32 of the lock actuation member 31 will be arranged close to the first side plate 13, and when the person secures the first bearing assembly 1 on the second side of the door 101, the person must take into account that the protrusion 32 of the lock actuation member 31 will be arranged close to the second side plate 13'.

As shown in fig. 13, the push element 41 and the additional push element 41 'of this embodiment of the panic lever device 100 are arranged outside the delimited area between the two side plates 13, 13'.

In the bearing assembly 1, 1 'of this embodiment of the emergency lever device 100, the first and second side plates 13, 13' are arranged symmetrically with respect to a plane of symmetry parallel to the first and second side plates 13, 13 ', which is located at the same distance from both side plates 13, 13'. Furthermore, the axis on which the lock actuation element 31 rotates is contained in said symmetry plane, this axis being perpendicular to the base plate 12.

The support assembly 1, 1 ' of this embodiment of the emergency lever device 100 comprises an alignment element 51 configured for coupling to the two side plates 13, 13 ' so that the two side plates 13, 13 ' remain parallel to each other and perpendicular to the base plate 12. Since the aligning element 51 is configured for keeping the first side plate 13 and the second side plate 13 'parallel to each other, when the pull rod 3 is pushed, it prevents friction from occurring and thus between the pushing element 41 and the first side plate 13 and between the additional pushing element 41' and the second side plate 13 ', and therefore, the pushing element 41 and the additional pushing element 41' rotate.

In order to be able to couple to the sideplates 13, 13', the alignment element 51 of this embodiment comprises at each of its ends a U-shaped projection 52, each projection 52 comprising two bars 54 facing each other and attached to each other by means of an additional bar 56, with a gap 53 between the two bars. Each side plate 13, 13 'comprises a through hole 15, 15' so that the calibration element 51 is introduced through both through holes 15, 15 'and slid in until the side plates 13, 13' abut the additional bar 56 so that each of the side plates 13, 13 'is accommodated in the gap 53 between the two bars 54 of each U-shaped projection 52, the calibration element 51 thus being coupled to both side plates 13, 13'. Fig. 3 shows the calibration element 51 and fig. 6 shows the calibration element 51 coupled to the two side plates 13, 13'.

The support assembly of this embodiment of the emergency lever device 100 comprises a sleeve 24 coaxial and external with respect to the axis of rotation 21, and a spring 61 arranged around the sleeve 24. The spring 61 is configured to return the panic lever device 100 to a standby state. The calibration element 51 comprises a projection 55 on which a spring 61 is held in place, the spring 61 being held in tension so that the calibration element 51 is fixed to the side plates 13, 13' by the action of the spring 61. It can be observed in fig. 6 that one end of the spring 61 is fixed to the pushing element 41 and the other end of the spring 61 is fixed to the additional pushing element 41 ', so that when the pushing element 41 and the additional pushing element 41' rotate as a result of the lever 3 of the emergency device 100 having been pushed, the spring 61 is subjected to a torsional force, so that when said torsional force disappears as a result of the lever 3 no longer being pushed, the spring 61 returns the emergency lever device 100 to the standby state. A spring 61 is fixed to the projection 55 of the calibration element 51, thereby pushing the calibration element 51 towards the side plates 13, 13 'so that the additional bar 56 of each U-shaped projection 52 abuts against the side plates 13, 13'.
