Modular device, reversible and polyvalent, of antipanic closure for mortise locks

Description

FIELD OF THE INVENTION

[0001] This invention relates to a device of modular design having a reversible nature and that can be actuated in a multipurpose manner by the panic locks that are installed in emergency exit doors and have a main lock mechanism, provided or not with a locking bolt, and/or upper (on the lintel) and lower (on the threshold) locking points, and/or side locking points on the door frame post, and where said main lock is actuated by means of a bar that is transversally installed on the door.

[0002] In particular, the object of this invention is intended for application in locks mortised in the thickness of doors.

STATE OF THE PRIOR ART

[0003] Two types of panic bars are known and frequently used in this field. One of them consists in a pushbar that is articulated at its ends to carry out, by means of two connecting rods, a collapsing rotation on the door; this type is known in this field by its English name, pushbar, which will be the one used hereinafter. The other type consists in a bar that includes an outer casing capable of linear movement perpendicular to the door; this type is known in this field by its English name, touchbar, which will be the one used hereinafter.

[0004] The current situation is that there are two different concepts of panic bar (pushbar and touchbar) and, within each one of them, there exist all the alternatives indicated above: a main lock having a bolt or lacking one; that the main lock also has to actuate side returns located at a different height than the door; that upper and lower returns also have to be actuated from the main lock.

[0005] The document WO 2008/043868 A1 discloses a reversible, multipurpose modular panic closure device that is representative of the state of the art.

[0006] However, each one of the known options corresponds nowadays to its own and exclusive design such that manufacturers and the distribution chain of this type of product face big design, material-procurement, production, storage and distribution problems.

DESCRIPTION AND ADVANTAGES OF THE INVENTION

[0007] In contrast to this state of affairs, this invention proposes a device of a modular and compact design that is going to allow it to be applied to the different alternatives of execution existing nowadays - described above - and particularly for mortise locks.

[0008] To this end, the proposed device comprises a case that is fastened to a door by means of a base plate, a first-order lever that has a vertical axis of rotation in the case, and a cam with a reciprocal topography of facing surfaces that belong to the base plate and to a floor wall of the case, this cam having its virtual axis of rotation in a hollow that is reciprocal to a square shaft of a lock mortised in the thickness of the door, this hollow being in a shaft journal that is reciprocal to a bearing of the base plate, the case of which has a first vertical sidewall provided with a complementary window of a shaft hub of a connecting rod of a pushbar of a panic locking mechanism installed across the width of the inner side of the door, there being in this first sidewall at least one reciprocally wide slot of the thickness of a tongue belonging to an end swinging arm of a panic locking device actuated by means of a touchbar, wherein , when the use of a pushbar-type panic lock is preferred, the first-order lever of which has a first arm in contact with a projecting part of the shaft hub on a face thereof that is frontal with regard to its rotation during the collapse of the connecting rod, and wherein, when the use of a touchbar-type panic lock is preferred, the touchbar is actuated and the tongues make the first-order lever rotate, said first-order lever having a second arm with its front in contact with a protruding part of the cam on a face thereof that is rear with regard to the rotation of the square shaft consistent with the opening of the mechanism of the mortise lock. In this mechanical design, the following conditions are met with regard to the position of assembly of the device on the door: that the body of the case is symmetrical in relation to the transverse and horizontal mid plane thereof; that the base plate is symmetrical in relation to its transverse and horizontal mid plane; and that the first-order lever is symmetrical in relation to its transverse and horizontal mid plane.

[0009] According to this setup, when the use of a pushbar-type panic lock is desired, the hub of the shaft of the connecting rod of the corresponding pushbar is coupled in the window of the first sidewall of the case, whereupon the second lug stays (according to the direction of rotation of the opening of the lock) behind the first arm of the first-order lever; on the other hand, since the second arm also stays behind the first lug associated with the cam, and since this cam is coupled to the square shaft of the mortise lock, it turns out that, upon the actuation of the pushbar, the second lug makes the first-order lever rotate and, in turn, the latter makes the cam rotate, dragging with it the square shaft of the mortise lock.

[0010] On the other hand, when the use of a touchbar-type panic lock is preferred, the slots of the first sidewall of the case come into play such that the tongues of the end swinging arm characteristic of the touchbar go into them to end positioned (as in the case of the second lug of the pushbar) behind the first arm of the first-order lever; then, when the touchbar is actuated, the tongues make the first-order lever rotate and, as before, the second arm thereof will make the cam that transmits the rotation of the square shaft rotate, causing the mortise lock to open.

[0011] That said, the properties of the device have been explained as for a compact, modular and multipurpose design as regards its application for pushbar and touchbar panic locks alike. To use the reversibility property such that the same device may be used for doors opening to the left or to the right, it will suffice to invert the position of the case from top to bottom without it being necessary to do the same with the first-order lever; as for the cam and the base plate, the inversion or not of their position following the inversion of the case might not be necessary, in each case depending on the direction of rotation required for the square shaft of the mortise lock.

DESCRIPTION OF A PREFERRED EMBODIMENT

[0014] In relation to the drawings and reference numbers listed above, a preferred embodiment of the object of the invention is depicted in the attached plans that is related to a device of modular design, specially intended for application in locks that are mortised in the thickness of doors, that is reversible and can be actuated in a multipurpose manner by the panic locks that are installed in emergency exit doors and have a main lock mechanism, provided or not with a locking bolt, and/or upper (on the lintel) and lower (on the threshold) locking points, and/or side locking points on the door frame post, and where said main lock is actuated by means of a bar that is transversally installed on the door.

[0015] As Figure 1 shows, said device comprises a case (1) that is fastened to a door (2) by means of a base plate (3), a first-order lever (4) that has a vertical axis of rotation (4a) in the case (1), and a cam (5) with a reciprocal topography of facing surfaces that belong to the base plate (3) and to a floor wall (1f) of the case (1), this cam (5) having its virtual axis of rotation in a hollow (5a) that is reciprocal to the square shaft (6a) of a lock (6) mortised in the thickness of the door (2), this hollow being in a shaft journal (5c) that is reciprocal to a bearing (3a) of the base plate (3), the case (1) of which has a first vertical sidewall (1a) provided with a complementary window (1c) of the shaft hub (7b) of the connecting rod (7a) of a pushbar (7) of a panic locking mechanism installed across the width of the inner side of the door (2), there being in this first sidewall (1a) at least one reciprocally wide slot (1d) of the thickness of a tongue (8a) belonging to the end swinging arm (8) of a panic locking device actuated by means of a pushbar, the first-order lever (4) of which has a first arm (4b) in contact with a projecting part (7c) of the shaft hub (7b) on a face thereof that is frontal with regard to its rotation during the collapse of the connecting rod (7a), the first-order lever (4) of which has a second arm (4c) with its front in contact with a protruding part (5b) of the cam (5) on a face thereof that is rear with regard to the rotation of the square shaft (6a) consistent with the opening of the mechanism of the mortise lock (6). According to a preferred embodiment, it is true that the vertical axis of rotation (4a) of the first-order lever (4) has its ends resting on seats included in the case (1) which, as can be seen in Figures 1, 2 and 5, are folds (1e) of the second vertical sidewall (1b) of the case (1); likewise, the following is true: that in the first sidewall (1a) two are the slots (1d) that are provided for as many other tongues (8a) of the end swinging arm (8) of a pushbar-type panic locking mechanism; that the protruding part (5b) of the cam (5) is a first lug; and that the projecting part (7c) of the shaft hub (7b) of the connecting rod (7a) is a second lug.

[0016] Figures 2 to 4 illustrate the application of the invention for a pushbar-type panic bar and are useful to explain its simple operation. Figures 2 and 3 relate to the neutral or rest state of the device, where the second lug (7c) stays behind the first arm (4b) of the first-order lever (4) (according to the stated convention for the direction of rotation of the opening manoeuvre), whilst the first lug (5b) of the cam stays front of the second arm (4c) of said first-order lever (4); when the bar (7) is lowered, the second lug (4b) causes a rotation of the first-order lever (4) which, through its second arm (4c) and the first lug (5b), is transmitted to the cam (5) which, due to being coupled to the square shaft (6a), causes in the latter the rotation needed to open the lock (6), this being the final position that is depicted in Figure 4.

[0017] Figure 5 illustrates the application of the proposed device for a touchbar-type panic lock, from where it may be deduced that the opening manoeuvre is identical to that explained for the pushbar, with the sole particularity that the tongues (8a) are now in charge of the function entrusted before to the second lug (7c).

[0018] According to other particularities of the invention, the following is true in the proposed device and with regard to the assembly position of the case (1) on the door (2): that the body of the case (1) is symmetrical in relation to the transverse and horizontal mid plane thereof; that the base plate (3) is symmetrical in relation to its transverse and horizontal mid plane; and that the first-order lever (4) is symmetrical in relation to its transverse and horizontal mid plane. With these conditions, a reversible application of the device is obtained, it being possible to use it for doors opening to either the right or the left, it sufficing to this end to turn the case (1) upside down and, according to the direction of rotation that is required for the square shaft (6a), also the cam (5) and the base plate (3) or not; evidently, the rotation of one of the these two parts involves that of the other.

[0019] As for the assembly of the cam (5), another particularity of the invention consists in the topography of the cam (5) being reciprocal to a seat (1g) that has been made in the floor wall (1f) of the case (1) as well as it forming (Figure 5) a projecting pin (5d) that is reciprocal to a mortise (3b) made in the base plate (3).
