Abstract
The invention relates to a sliding panic bar comprising a casing (3) which is designed to incorporate an electrical installation and rails for self-locking latch bodies (6, 7, 8) which are released by the actuation of a blocking lever (12) centralising different actuation situations. The activation of the bar by pressure is carried out by means of a set of shuttles (41, 42, 43), a synchronous axis (37) and retaining springs (49). The system comprises a mechanism for adapting to the width of the door, for facilitating the use of the system by physically handicapped people, and for adapting to vertical bolt systems with the latch in a vertical or horizontal position. The locks of the system are adjustable in order to be able to absorb possible dilation.

- the rocking-side hinged latch (5) has a locking mechanism in spagnolettes and is maintained self-locked when positioned on a impeller (94/94′) hooked on rod-rocker (92) and positioned on its shaft (95) within an adjustable side lock supporting element (91), and remains unoperated in the remaining rocking-side hinged sequences wherein the latch (5) is not positioned on the impeller (94/94′) located within adjustable side lock supporting element (91).
Sliding and modular panic bar with minimum movements, according to claim I, characterized in that inside the rails a first supporting element (9) is housed, which joins together the head frames (10, 10′) having a double circular sector for achieving the double depression of the latch (5) on the positioning shafts (20, 21) thereof, the elevated self-locking member (6, 7, 8) of the latch (5) being displaced from its geometric center for receiving the recuperating rod (15) which, by means of the groove therein, moves along the shaft (21) of the latch (5) together with its compression spring (M15), the locking lever (12) having the function of serving as unlocking element, when a follower (11) is actuated on its external and adjacent addendum, sometimes, on a shaft (64) for use in the exit of physically disabled people, also having the function of armor in electrical configurations, housing its return spring and ensuring in its embossment, in case of fire when a fuse (28) is melted, the locking lever (12) is retained by a RF spring (27) maintaining the locking, the head frames (10, 10′) being assembled, at the top, with a supporting element of coil (18) making up the head block stiffness.
Sliding and modular panic bar with minimum movements, according to the preceding claims, characterized in that the modular skid (31) is crimped to an electromagnetic armor (45) made of different alloys, same as its core (46) in inhibition applications, being a solid of equal resistance and having at its anterior part a triangular-prism configuration, maintaining in the middle part thereof the parallelism by the situation of some its transmitting rod (14), being a bushed separator with suitable polyamide (39, 40) limiting the movement thereof in the groove of the sliding skid, preventing the metal collision of the latch shaft on the frames (10, 10′), forming on the back an open crenellation wherein a bushing (36) for moving a synchronous shaft (37) is housed.
Sliding and modular panic bar with minimum movements, according to the preceding claims, characterized in that the locking mechanisms in spagnolette modularly include the same latch (5) of the main bar, the same self-locking system (6, 7, 8), the same pivoting rod (15) and identical retaining rods (14), these rods being articulated in a skid (76) grooved at its base for limiting its movement by a boss (81) integral with the frame (74) and covered with a polyamide guide bushing (2), and which at its front retains a return spring (78) of a stem (77) attached to the frame (74) by a shaft (79), this stem being guided in its extreme by the crenellation included by the frame (74);
- the skid housing a guide support element (83), function of which is to retain a corresponding shank or spagnolette (84) by attaching a screw (T83).
Sliding and modular panic bar with minimum movements, according to the preceding claims, characterized in that when a bar tandem is joined for physically handicapped people, the sliding panic bar further comprises a shaft (64) which with a minimum movement and extensive post-race, enables the unlocking by acting on the complementary bar of some “inverted levers”, frame (35, 35′), pushing the shuttle (43) and because of the nexus of a spagnolette (53) to the rod tandem (51, 52), moving with minimum effort the shaft (64) from resting position, a spring (65) being the only element to restore the operating cycle of the rod or shaft (64).
Sliding and modular panic bar with minimum movements according to the preceding claims, characterized in that a guide supporting element 87 is generated, which is common for vertical and horizontal mechanisms, with crenellated design determining a three-point plane for adjusting to the spagnolette 84 with a diameter slightly greater than said spagnolette that enables inserting a bushing 87′ for stiffening the guide supporting element 87, allowing no deviation at the time of attaching the supporting element 87 to the frame, then moving this bushing 87′ from the crenellations being, positioned by gravity without interferences on the lower supporting elements of the spagnolettes, such that the alignment is established with this simple operation without producing any friction during the normal movement of the spagnolette 84, furthermore a precise adjustment is achieved when attaching the spagnolettes 84 in their guide supporting element 83 through the screw, and pressing thereof on the second bushing 61′ located on the rod pin retaining the spagnolettes 61, once locked the spagnolette shank 84 this adjustment bushing 61′ is removed and discarded, being the combination well regulated.
Sliding and modular panic bar with minimum movements, according to the preceding claims, characterized in that these include, for minimizing the friction on the latches and rolling planes, a supporting element 88 with two crenellated embossments serving as “bed” for a solid impeller 88′ an in an envelope 89 making up the supporting element-impeller 88-88′ sub-assembly, also a window is opened for the correct assembly of these three elements;

- it also starts from a supporting element 91 jointly connected with a threaded and milling guide bushing 91′, this supporting element 91 crenellated in cross-section houses a rocker 92 bearing a double coil spring 93 and inserts into the crenellation of the supporting element 91 and retained by the rocker shaft 95, being attached through drill-holes 91″, this rocker 95 joins with sliding adjustment two male-female impellers 94, 94′ rigidly assembled, the position of the impellers 94-94′ with respect to the plane of incidence of the latch is controlled by a single screw 96 which acts on the radial addendum 92′ of the rocker, the pressure generated by the return spring 93 itself being sufficient for stabilizing the attachment of the screw 96 in the desired position;
- once installed the frame supporting element 91 in the right place, the envelope 90 is attached to supporting element 91, this resulting configuration allows the adjustment and readjustment, in case of expanding the parameters implanted, without using the classic supplements of conventional locks.
