Description

Push bar device to open emergency exits.

Field of the Invention

This invention concerns a bar of called panic, which are installed transverse by the inside side of an emergency exit door of a room, with the mission of producing the opening of the door just by exercising on it a pressure, even involuntary when a body is pushed by others trying to escape precipitously.

In particular, these bars are classified in two types: one of them is known by its English name of "pushbar" and consists of a rotating bar that, by each connecting rod, is articulated at its ends to make a gloom over the door; the other type is known by name, also in English, of "touchbar" and consists of a bar that incorporates an outer shell with linear movement capability perpendicular to the door.

The object of this invention is applicable to a "pushbar" type bar.

Prior art

The application of these panic bars (both if it is pushbar as if it is touchbar) it is widely used for wooden doors or other material of similar and opaque thickness, There are various solutions in this regard; ones, assembly superimposed on both the push bar (by its very nature) as of the rest of the drive transmission device by means of fallebas that operate on two high closing points and low that close on the lintel and the threshold of the frame on which  close the door; others, where only the bar is visible and the rest of the device goes inside the thickness of the door.

When it comes to applying these bars to glass doors, regardless of powerful reasons aesthetic, internal mounting is not possible in the usual thickness of the crystal; and the overlay mount, on the one hand, offers fixation problems that lead to risk of breakage of the crystal, and on the other hand, the result is appalling and unsightly, even when the glass has a profile frame of metal carpentry and the central locking mechanism, high and low, with the fallebas, they are of width as much equal to the scarce measure of the side of the metalwork profile that frames the crystal.

Explanation of the invention and advantages

Faced with this state of affairs, this invention advocates a push bar to open emergency exits, comprising a central mechanism, which lacks a latch and is operated by pressing the push bar, and two mechanisms closing, high point and low point, which have respective latches, upper and lower, as well as a recovery mechanism which is at the opposite end of the central mechanism, whose mechanism  central consists of a rotating lever that, with respect to the base Anchoring the central mechanism case, it has a part adjacent in which it is keyed with a square shaft that it is actuated by pressing the push bar and a remote part in which this rotary lever has a neckline in which with rotary adjustment is located a button that is installed in one of the two arms of a bent lever that its vertex rotates on a shaft fixed in the central mechanism housing in a place that is farther from said anchor base than the button itself and whose angled lever has the end of its other arm adjacent to said anchor base and applied from top to bottom on a projection of a vertical top sliding plate on which there is a first pivot which is located in a first radial groove of a rotating disk which has a second radial groove in diametral opposition and in the which is located a second pivot of a sliding vertical plate bottom, whose upper sliding vertical plate and vertical plate lower slider are likely to be coupled with ones respective failed higher and failed lower which are actuators of said high point closing mechanisms and of low point. In this constitution of the central mechanism is achieved place the square axis as close as possible to the base of anchoring of the box, which, in conjunction with the chain Kinematics integrated by the combined action of the levers rotary and angled, allows to achieve a large multiplication of Pulsed path of the push bar that transforms into a wide vertical displacement to exert an effective action of closure at high and low points; and all this, enabling the height of the central mechanism, with respect to the base of its box is smaller than the inside of the metal profiles usually used to make the glass mounting frame. So is possible to mount the central, high point, low point mechanisms and, of course, the fallebas, inside the amounts of the metal carpentry profile frame through operations simple sliding and mooring explained below With the help of the drawings.

Another feature of the invention is that the push bar crossbar is the pressing element and its cross section has sliding adjustment with respect to windows existing at the air end of connecting rods that on the other end are likely to receive a screw capable of screwing in any one of two axial holes practiced in the square shaft ends, there is a captive screw which curls through the wall of the window invading it with its tip. This constitution facilitates a simple assembly of the bar, inserting it through the windows of both cranks without these are still fixed, then the connecting rods slide to their end of the crossbar and are fixed to the respective mechanism (the central and opposite to it, which incorporates rotating means of elastic recovery), and finally the prisoners are placed They just secured the crossbar assembly. On the other hand, this constitution allows an easy longitudinal adaptation of the crossbar, so that, starting from the longest expected length, just with cutting it for another smaller measure adapted to the size of each installation.

Other particularities of the invention are refer to means for adjusting the length of the latches of closure of the high and low points. For the high point the latch upper is hollow and has internal reciprocal threading of a spike-shaped and first internal support locknut mounted by the upper end of the latch itself higher. And for the low point the bottom latch is solid and it has a threaded spike tail in combination with the inside a support and a second locknut mounted by the upper end of the support.

In both cases the operation is as simple as thread two pieces together until the desired measure is achieved, moment in which the lock nut that secures the chosen position.

Exhibition of a preferred embodiment

Regarding the drawings and references above listed, an execution mode is illustrated in the attached drawings preferred object of the invention, relative to a bar pushbar push button (figure 4) to open outputs of emergency, which is installed in a framed glass door (figure 1) in a frame of metalwork profile and that it comprises a central mechanism (A), which lacks a latch and is operated by pressing the push bar, and two mechanisms closing, high point (B) and low point (C), which have respective latches, upper (14) and lower (15), as well as a recovery mechanism (D) that is at the opposite end of the central mechanism (A).

As Figure 8 illustrates, the central mechanism (A) consists of a rotary lever (3) which, with respect to the base of anchor (13a) of the central mechanism housing (13), has a adjacent part where it is keyed with an axis of square (8) which is actuated by pressing the push bar and a remote part in which this rotary lever (3) has a neckline (3a) in which with a rotary adjustment a button is located (4a) which is installed in one of the two arms of a lever angled (4) that its vertex rotates on an axis (4b) fixed in the box of the central mechanism (13) in a place that is further from said anchor base (13a) than the button itself (4a) and whose lever angled (4) has the end of its other arm adjacent to said anchor base (13a) and applied from top to bottom on a projection (5a) of an upper sliding vertical plate (5) in which there is a first pivot (5b) that is located in a first radial groove (7a) of a rotating disk (7) having a second radial groove (7b) in diametral opposition and in which a second is located pivot (6a) of a lower sliding vertical plate (6), whose vertical sliding top plate (5) and vertical sliding plate lower (6) are likely to be coupled with respective failed higher (11) and failed lower (12) that are actuators of said high point (B) and low point closing mechanisms (C). The functionality of this mechanism, with its great capacity scroll multiplier, it follows from the mere observation of figures 9 and 10; where, along with figure 8, it see that pressing the crossbar (9) produces the counterclockwise rotation of the rotary lever (3) which, through the button (4a), produces the hourly rotation of the angled lever (4) acting on the projection (5a) driving the descent of the vertical sliding plate upper (5) which, with its first pivot (5b), rotates the disc rotary (7) that drives the second pivot (6a) and ascends the vertical sliding bottom plate (6). This functional effectiveness is achieved within measures so small that they allow location of the mechanism inside the uprights of the profile of metal carpentry of the frame (2), illustrated in figures 5, 6 and 7; to in this regard, the assembly of the central mechanisms (A) and of recovery (D) consist of sliding them inside said uprights until reaching its operational location, in which they are moored

Another feature of the invention is that the crossbar (9) of the push bar is the pressing element and its cross section has sliding adjustment with respect to windows (10a) existing at the air end of connecting rods (10) that by their other end are likely to receive a screw (10b) capable of screwing in any one of two axial holes (8a) practiced at the ends of the square shaft (4), existing a captive screw (10c) that screws through the wall of the window (10a) invading it with its tip. In this way, for mount the push bar (figure 11) the crossbar (9) is placed to through the windows (10a) of both cranks (10), they slide these to its end of the crossbar (9), where (see details enlarged in this figure 11) proceed with the fastening with the screws (10b) to finally place the prisoners (10c) tight on the periphery of the crossbar (9). Here you can clearly see what said above regarding the ease of longitudinal adaptation of the crossbar (9) for lower lengths, by simple cutting from of a single measure corresponding to the largest size envisaged in the usual facilities.

In the central mechanism (A) is provided (figures 12 and 13) an external actuator (18) which, provided with a eccentric, can open from the outside if necessary, producing the upward drive of the sliding vertical plate bottom (6) which, through the rotating disk (7), drives the lowering of the upper sliding vertical plate (5), which, by means of the upper (11) and lower (12) fallebas, the retraction of the upper (14) and lower (15) latches.

Another peculiarity of the invention is that (figures 14 and 15) the upper latch (14) is hollow and has reciprocal internal threading of a support (14a) in the form of spike and of an internal first locknut (14b) mounted by the upper end of the upper latch itself (14). In this way there is a wide range of regulation of the effective length of the upper latch (14) and, therefore, of the degree of appearance of the same to penetrate your strike effectively, even compensating the clearances between the mounting frame (2) of the glass and the frame on which the door closes. Regulation it's a simple maneuver like screwing the top latch (14) on the support (14a) to the desired point and then screw on stop the first locknut (14b).

Similarly, to regulate the length and peek of the lower latch (15), another peculiarity of the invention consists in (figures 16 and 17) this lower latch (15) is solid and has a threaded spike tail in combination with the inside of a support (15a) and a second locknut (15b) mounted by the upper end of the bracket (15a). Then, the bottom latch tail will have to be screwed (15) inside the support (15a) to the desired point, moment in which the second locknut (15b) will be placed by threading full.
