Description

[0001] PUSH HORIZONTAL BAR HANDLE FOR A PANIC LOCK AND RELATED ASSEMBLY

[0002] METHOD

[0003] DESCRIPTION

[0004] The present invention relates to a push horizontal bar handle for a panic lock and the corresponding assembly method.

[0005] The panic bar is expressly considered an accessory of the door.

[0006] Its installation is, in 99% of cases, carried out directly by the door installer. The installation time of a panic bar and the resulting ease of assembly are strong factors influencing the choice of the product.

[0007] Handling the bar in a panic bar commercially referred to as type A (which is the bulkiest element) is often difficult during the installation phase.

[0008] It often happens that more than two hands are required to install a panic bar, leading to considerable cost increases.

[0009] Current products involve an installation sequence that results in unstable handling of the bar during fastening.

[0010] The cutting of the bar itself, whose length must be trimmed to make it compatible with the width of the door, must be very precise; otherwise, any error cannot be compensated.

[0011] In addition, the fastening between the bar and the arms is currently a critical point in many existing panic bars.

[0012] It often happens that when the panic bar is pressed on the hinge side, the bar becomes misaligned, which also causes a loss of rotation of the square spindle of the handle.

[0013] The technical problem addressed by the present invention is therefore to provide a push horizontal bar handle for a panic lock that eliminates the technical drawbacks complained of in the prior art. Within this technical task, one object of the invention is to provide a push bar handle for a panic lock that can be installed correctly with extreme ease. Another object of the invention is to provide a push bar handle for a panic lock having an extremely robust structure capable of operating correctly regardless of the point where the bar is pressed.

[0014] The technical problem, as well as these and other objects, according to the present invention, are achieved by providing a push horizontal bar handle for a panic lock comprising a right box and a left box for fastening the handle to a frame, a right arm articulated to the right box and a left arm articulated to the left box, a lock-actuating mechanism housed in either the right or the left box, wherein the bar comprises a longitudinal body, a right terminal, and a left terminal, characterized in that said bar has means for adjusting its length and coupling means with a slotted joint between the right arm and the right terminal and between the left arm and the left terminal.

[0015] In a preferred embodiment of the invention, said adjustment means provide a telescopic engagement between the right terminal and a right end of the longitudinal body of the bar, and / or between the left terminal and a left end of the longitudinal body of the bar.

[0016] In a preferred embodiment of the invention, said right terminal comprises an outer portion relative to said longitudinal body of said bar and an inner portion inside said longitudinal body of said bar, and said left terminal comprises an outer portion relative to said longitudinal body of said bar and an inner portion inside said longitudinal body of said bar.

[0017] In a preferred embodiment of the invention, said adjustment means comprise a guided sliding slot inside the right end of the longitudinal body of the bar, housing the portion of said right terminal located inside said longitudinal body of said bar, and / or a guided sliding slot inside the left end of the longitudinal body of the bar, housing the portion of said left terminal located inside said longitudinal body of said bar.

[0018] In a preferred embodiment of the invention, said coupling means are configured and arranged for a top-down coupling of the right terminal to the right arm and of the left terminal to the left arm.

[0019] In a preferred embodiment of the invention, said coupling means comprise a slotted guide formed in the outer portion of said right terminal and engaged in a counter-slotted guide formed in a cradle- shaped end of the right arm, where a lower half of the right end of the longitudinal body of the bar is housed, and a slotted guide formed in the outer portion of said left terminal and engaged in a counter-slotted guide formed in a cradle-shaped end of the left arm, where a lower half of the left end of the longitudinal body of the bar is housed.

[0020] In a preferred embodiment of the invention, the outer portion of said right terminal comprises a cradle for housing an upper half of the right end of the longitudinal body of the bar, and the outer portion of said left terminal comprises a cradle for housing an upper half of the left end of the longitudinal body of the bar.

[0021] In a preferred embodiment of the invention, clamping means are provided for the right terminal and the left terminal.

[0022] In a preferred embodiment of the invention, said clamping means are configured and arranged to fasten the right terminal to the right arm and jointly clamp the right end of the longitudinal body of the bar between the right terminal and the right arm, and to fasten the left terminal to the left arm and jointly clamp the left end of the longitudinal body of the bar between the left terminal and the left arm.

[0023] In a preferred embodiment of the invention, said clamping means comprise tensioning screws.

[0024] The present invention also discloses a method for assembling the handle, in which the assembly sequence of the bar is more systematic and easier to carry out.

[0025] First, the two boxes are installed on the sides of the door. One is the main box (containing the lockactuating mechanism), and the other, secondary and symmetrical to the first, serves as a support for the cross bar.

[0026] Subsequently, after being trimmed to size, the longitudinal body of the bar is coupled to the two terminals at both ends, and the bar is lowered from above until the two terminals engage the two arms already fastened to the two boxes. The telescopic coupling of the two terminals to the longitudinal body of the bar makes any cutting error more manageable and significantly increases the range of compensation for possible trimming errors in length.

[0027] After positioning the bar, the tensioning screws are fastened, making the terminals structurally continuous, rigid, and firmly integral with the longitudinal body of the bar.

[0028] At the same time, the fastening between the bar and the arms is reinforced, which, as previously indicated, is currently a critical point in existing panic bars.

[0029] Further features and advantages of the invention will become more apparent from the description of a preferred, though not exclusive, embodiment of the push horizontal bar handle for a panic lock according to the invention, illustrated by way of example and without limitation in the accompanying drawings, in which:

[0030] Figure 1 shows a front view of the assembled handle;

[0031] Figure 2 shows a front view of the disassembled handle;

[0032] Figure 3 shows a front view of the bar disassembled from the terminals;

[0033] Figure 4 shows a rear axonometric view of the disassembled handle;

[0034] Figure 5 shows a vertical section of detail A of Figure 1 in a plane containing the central axis of the bar.

[0035] With reference to the mentioned figures, a handle 1 with a horizontal push bar 2 for a panic lock is shown.

[0036] The handle 1 comprises a right box 3 and a left box 4 for fastening the handle 1 to a frame, a right arm 5 articulated to the right box 3 and a left arm 6 articulated to the left box 4, and a lock-actuating mechanism, not shown, housed in either the right box 3 or the left box 4.

[0037] The fastening boxes 3, 4 are horizontally aligned at a distance equal to the width of the frame and support the arms 5, 6 with horizontal pivot axis L.

[0038] The arms 5, 6 are symmetrical and support the bar 2 horizontally. The bar 2 is rotatable about the pivot axis L between a position farther from the frame corresponding to the locked condition of the lock and a position closer to the frame corresponding to the unlocked condition of the lock.

[0039] The bar 2 comprises a longitudinal body 2’, a right terminal 7, and a left terminal 8. Advantageously, the bar 2 has means for adjusting its length.

[0040] In the illustrated example, the adjustment means provide a telescopic engagement between the right terminal 7 and a right end 2d of the longitudinal body 2’ of the bar 2, and between the left terminal 8 and a left end 2s of the longitudinal body 2’ of the bar 2.

[0041] Advantageously, the handle 1 also has slotted coupling means 9, 10, 11, 12 between the right arm 5 and the right terminal 7, and between the left arm 6 and the left terminal 8.

[0042] The right terminal 7 comprises a portion 13 external to the longitudinal body 2’ of the bar 2 and a portion 14 internal to the longitudinal body 2’ of the bar 2.

[0043] The left terminal 8 likewise comprises a portion 16 external to the longitudinal body 2’ of the bar 2 and a portion 17 internal to the longitudinal body 2’ of the bar 2.

[0044] The adjustment means of the length of the bar 2 comprise a guided sliding slot 15 inside the right end 2d of the longitudinal body 2’ of the bar 2, housing the portion 14 of the right terminal 7 internal to the longitudinal body 2’ of the bar 2, and a guided sliding slot 18 inside the left end 2s of the longitudinal body 2’ of the bar 2, housing the portion 17 of the left terminal 8 internal to the longitudinal body 2’ of the bar 2.

[0045] In practice, the sliding slot 15 extends from the right end 2d of the longitudinal body 2’ of the bar 2 and has a shape matching the internal portion 14 of the right terminal 7; likewise, the sliding slot 18 extends from the left end 2s of the longitudinal body 2’ of the bar 2 and has a shape matching the internal portion 17 of the left terminal 8.

[0046] In this way, as will be explained in more detail below, during assembly of the handle 1 it is possible to adjust the degree of penetration of the right terminal 7 and the left terminal 8 into the longitudinal body 2’ of the bar 2 to compensate for possible errors in cutting the longitudinal body 2’ of the bar 2 to size.

[0047] The coupling means 9, 10, 11, 12 are configured and arranged for a top-down coupling of the right terminal 7 to the right arm 5 and of the left terminal 8 to the left arm 6.

[0048] The coupling means 9, 10, 11, 12 comprise, in detail, a slotted guide 9 formed in the external portion 13 of the right terminal 7 and engaged in a counter-slotted guide 10 formed in a cradleshaped end 19 of the right arm 5, where a lower half of the right end 2d of the longitudinal body 2’ ofthe bar2 is housed; and a slotted guide 11 formed in the external portion 16 of the left terminal 8 and engaged in a counter-slotted guide 12 formed in a cradle-shaped end 20 of the left arm 6, where a lower half of the left end 2s of the longitudinal body 2’ of the bar 2 is housed.

[0049] The external portion 1 of the right terminal 7 comprises a cradle 21 for housing an upper half of the right end 2d of the longitudinal body 2’ of the bar 2.

[0050] The cradles 19, 21 completely enclose the right end 2d of the longitudinal body 2’ of the bar 2, reproducing its external profile.

[0051] The external portion 16 of the left terminal 8 comprises a cradle 22 for housing an upper half of the left end 2s of the longitudinal body 2’ of the bar 2.

[0052] The cradles 20, 22 completely enclose the left end 2s of the longitudinal body 2’ of the bar 2, reproducing its external profile.

[0053] The handle 1 further comprises clamping means 23, 24 for the right terminal 7 and the left terminal 8.

[0054] The clamping means 23 for the right terminal 7 are configured and arranged both to fasten the right terminal 7 to the right arm 5 and to clamp the right end 2d of the longitudinal body 2’ of the bar 2 between the right terminal 7 and the right arm 5.

[0055] The clamping means 23 for the right terminal 7 are formed in particular by a tensioning screw 23. The tensioning screw 23 engages a through hole 25 of the right arm 5 and a blind hole 26 of the right terminal 7 aligned with the through hole 25.

[0056] The through hole 25 of the right arm 5 is formed at the cradle-shaped end 19 of the right arm 5 and is accessible from underneath the cradle-shaped end 19 of the right arm 5, while the blind hole 26 of the right terminal 7 is formed at the external portion 13 of the right terminal 7.

[0057] The clamping means 24 of the left terminal 8 are configured and arranged both to fasten the left terminal 8 to the left arm 6 and to clamp the left end 2s of the longitudinal body 2’ of the bar 2 between the left terminal 8 and the left arm 6.

[0058] The clamping means 24 of the left terminal 8 are formed in particular by a tensioning screw 24.

[0059] The tensioning screw 24 engages a through hole 27 of the left arm 6 and a blind hole 28 of the left terminal 8 aligned with the through hole 27.

[0060] The through hole 27 of the left arm 6 is formed at the cradle-shaped end 20 of the left arm 6 and is accessible from underneath the cradle-shaped end 20 of the left arm 6, while the blind hole 28 of the left terminal 8 is formed at the external portion 16 of the left terminal 8.

[0061] The assembly method of the handle 1 comprises the following steps:

[0062] - fastening the right box 3 and the left box 4 to the frame at a distance determined by the width of the frame;

[0063] - cutting the longitudinal body 2’ of the bar 2 to a size determined by the width of the frame;

[0064] - engaging the right terminal 7 with the right end 2d of the longitudinal body 2’ of the bar 2;

[0065] - engaging the left terminal 8 with the left end 2s of the longitudinal body 2’ of the bar 2.

[0066] The right terminal 7 and the left terminal 8 have a telescopic engagement with the longitudinal body 2’ of the bar 2, in the sense that the degree of their intersection with the longitudinal body 2’ of the bar 2 is adjustable by relative sliding.

[0067] At this point, by adjusting the degree of intersection of the right terminal 7 and the left terminal 8 with the longitudinal body 2’ of the bar 2, the right terminal 7 is coupled to the right arm 5 and the left terminal 8 is coupled to the left arm 6 by vertical alignment and subsequent engagement of the slotted guide 9 in the counter-slotted guide 10 and of the slotted guide 11 in the counter-slotted guide 12.

[0068] The engagement of the slotted guide 9 in the counter-slotted guide 10 and of the slotted guide 11 in the counter-slotted guide 12 locks the position of the right terminal 7 and the left terminal 8 in the direction of axis L.

[0069] The degree of intersection of the right terminal 7 and the left terminal 8 with the longitudinal body 2’ of the bar 2 varies depending on the amount of cutting error of the longitudinal body 2’ of the bar 2 to be compensated.

[0070] At this point, the tensioning screw 23 is applied, which fastens the right terminal 7 to the right arm 5 and jointly clamps the right end 2d of the longitudinal body 2’ of the bar 2 between the right terminal 7 and the right arm 5.

[0071] Similarly, the tensioning screw 24 is applied, which fastens the left terminal 8 to the left arm 6 and jointly clamps the left end 2s of the longitudinal body 2’ of the bar 2 between the left terminal 8 and the left arm 6.

[0072] In particular, the right end 2d of the longitudinal body 2’ of the bar 2 is clamped between the cradle 19 and the cradle 21, while the left end 2s of the longitudinal body 2’ of the bar 2 is clamped between the cradle 20 and the cradle 22.

[0073] The push horizontal bar handle for a panic lock thus conceived is susceptible to numerous modifications and variants, all falling within the scope of the inventive concept; furthermore, all details may be replaced by technically equivalent elements.

[0074] For example, the means for adjusting the length of the bar may be provided only at one of the two ends of the bar, so that only one of the two terminals is adjustable.

[0075] In practice, the materials used, as well as the dimensions, may be of any type depending on requirements and on the state of the art.
