Description

[0001] The present invention relates to an external controller for emergency devices.

[0002] In the background art, in doors in which emergency door handles or panic bars are to be installed, an external access apparatus is installed on the face arranged opposite to the face on which the emergency components are mounted.

[0003] Conventional apparatuses comprise a cylinder lock (operable using a corresponding coded key) through which it is possible to enable or disable the retraction of the spring latch and of the sliding latch (or other type of latch).

[0004] Technical solutions are known which involve the presence of a handle, controlled by the cylinder lock, through which it is generally possible to actuate the retraction of the spring latch, so allowing the door to also be opened from outside (i.e. from the opposite side of the door on which the emergency opening device is installed, such as a handle and / or a sliding bar).

[0005] Through the cylinder lock, it must be possible to enable and / or disable the external handle, so as to define a condition in which a rotation of the handle produces the opening of the door (handle enabled) by retracting the latches (spring latch or sliding latch) and a condition in which a rotation of the handle has no effect on the latches and therefore does not open the door (handle disabled).

[0006] The passage from one configuration of the handle to the other through rotations of the cylinder lock, imposed by a rotation of the respective coded key inserted in the lock, is generally obtained by means of mechanical contrivances that engage and / or disengage the shaft of the handle with / from the emergency opening device installed on the inner face of the door (this is because the emergency opening device must always be active in order to allow escape from the environment in all conditions).

[0007] These mechanical contrivances are fairly complex and take up considerable space, making it necessary to provide housings for conventional controllers of considerable size (compared to the traditional dimensions of a handle and of a corresponding covering plate), which protrude several centimeters from the surface of the door.

[0008] Furthermore, according to the type of installation planned (i.e. according to whether, when traction is applied on the handle to move the door away from the jamb, the door opens by rotating clockwise or anticlockwise), it is necessary to have external controllers with the handle installed on the right or on the left.

[0009] In order to overcome this drawback, the use is known of controllers that can be reconfigured, by modifying the side of installation of the handle and by making it possible to install it on any type of door.

[0010] Unfortunately these conventional solutions entail operations to mount and remove components, which introduce the possibility of error on the part of the operators when adapting the controller, and which require the use of tools and require specific skills that normally require special training.

[0011] The aim of the present invention is to solve the above-mentioned drawbacks, by providing an external controller for emergency devices that enables the handle to be enabled and disabled by means of the cylinder lock in a simple manner.

[0012] Within this aim, an object of the invention is to provide an external controller for emergency devices which offers reduced space occupation.

[0013] Another object of the invention is to provide an external controller for emergency devices which is constituted by components that are simple and compact, therefore generally not subject to malfunctions and breakage.

[0014] Another object of the invention is to provide an external controller for emergency devices that allows the arrangement of the handle to be inverted, so as to be adapted to doors that rotate clockwise and anticlockwise, in a simple manner.

[0015] Another object of the invention is to provide an external controller for emergency devices that allows the arrangement of the handle to be inverted, so as to be adapted to doors that rotate clockwise and anticlockwise, without the need for tools.

[0016] Another object of the invention is to provide an external controller for emergency devices that allows the arrangement of the handle to be inverted, so as to be adapted to doors that rotate clockwise and anticlockwise, even by operators with no specialist skills.

[0017] Another object of the present invention is to provide an external controller for emergency devices which is of low cost, easily and practically implemented and safe in use.

[0018] This aim and these and other objects which will become better apparent hereinafter are achieved by an external controller for emergency devices for opening doors to passages to access and exit an environment, said devices comprising actuation means for respective latches arranged on a face of the door directed toward the inside of the installation environment, said controller comprising a box-like body configured for the at least partial accommodation of an actuating member that can move along a stroke of predefined extent and of a cylinder lock, characterized in that it comprises a coupling unit interposed between a shaft of said actuating member and said actuation means for said latches, at least one tilting element, interposed between said coupling unit and the bit of said cylinder lock, and in that said coupling unit comprises a first contoured insert rigidly coupled to said shaft of said actuating member and a second insert rigidly coupled to said actuation means, said first and second insert being pivoted so that they can rotate with respect to an axis X, said tilting element comprising at least one pair of mutually opposite projections, which are configured to slideably engage respective contoured slots of said first and second insert, and at least one protrusion facing and proximate to the surface of a recess of said second insert, said tilting element being orientable, by virtue of the action of said bit of said lock which can be temporarily inserted into a trough of said element, facing and proximate thereto, between a first limit configuration in which said projections are accommodated within a portion of said slots which is proximate to a lateral surface of said box-like body and a second limit configuration, symmetrically opposite to the first limit configuration, a rotation of said actuating member producing in said first limit configuration, a rotation of said first and second insert and of said actuation means for said latches, in said second limit configuration, a rotation of said first insert and the abutment of said protrusion against the surface of said recess of said second insert which as a consequence is maintained in a fixed position, defining an idle stroke for said actuating member when said element is in said second limit configuration.

[0019] Further characteristics and advantages of the invention will become better apparent from the detailed description that follows of a preferred, but not exclusive, embodiment of the external controller for emergency devices, which is illustrated by way of non-limiting example in the accompanying drawings wherein: Figure 1 is an exploded schematic perspective view of an external controller for emergency devices according to the invention; Figure 2 is a schematic side view of the controller of Figure 1 in a first operative configuration; Figure 3 is a cross-sectional view taken along the line III-III in Figure 2 of the controller of Figure 1; Figure 4 is a schematic side view of the controller of Figure 1 in a second operative configuration; Figure 5 is a cross-sectional view taken along the line V-V in Figure 4 of the controller of Figure 1; Figure 6 is a schematic side view of the controller of Figure 1 in a third operative configuration; Figure 7 is a cross-sectional view taken along the line VII-VII in Figure 2 of the controller of Figure 1; Figure 8 is a schematic side view of the controller of Figure 1 in a fourth operative configuration; Figure 9 is a cross-sectional view taken along the line IX-IX in Figure 8 of the controller of Figure 1; Figure 10 is a cross-sectional view taken along the line X-X in Figure 8 of the controller of Figure 1; Figure 11 is a schematic front elevation view of the internal mechanisms of the controller of Figure 1 during operations to change the operative direction for the handle; Figure 12 is a schematic front elevation view of the internal mechanisms of the controller of Figure 1 at the end of operations to change the operative direction for the handle.

[0020] With reference to the figures, the reference numeral 1 generally designates an external controller for emergency devices according to the present invention.

[0021] Emergency devices are generally installed on doors to passages to access and exit an environment, and comprise actuation means (for example handles, sliding bars, push bars or push-pads and other, similar components). By acting on the actuation means it is possible to effect the retraction of respective latches, which can comprise components such as a spring latch, a sliding latch or shootbolts.

[0022] Such actuation means are arranged on a face of the door that is directed toward the inside of the installation environment.

[0023] The controller 1 comprises a box-like body 2 configured for the at least partial accommodation of an actuating member 3, such as a handle, a knob, a door pull or other, equivalent component, that can move along a stroke of predefined extent, and of a cylinder lock 4. The cylinder lock 4 can be operated in rotation using a corresponding key 5.

[0024] The controller 1 is intended to be mounted on the face of the door that is directed toward the outside of the installation environment.

[0025] The controller 1 comprises a coupling unit 6 interposed between a shaft 7 of the actuating member 3 and the actuation means for the latches.

[0026] The controller 1 further comprises at least one tilting element 8, interposed between the coupling unit 6 and the bit 9 of the cylinder lock 4.

[0027] In the present description, the term bit 9 means an actuation cam that rotates integrally with the rotor of the cylinder lock 4 (which can be made rotate by acting on the coded key 5, when the key is correctly mated to the lock 4).

[0028] According to the invention, the coupling unit 6 comprises a first contoured insert 10 rigidly coupled to the shaft 7 of the actuating member 3 and a second insert 11 rigidly coupled to the actuation means for the latches.

[0029] The first insert 10 and the second insert 11 are pivoted so that they can rotate with respect to an axis X. The tilting element 8 comprises at least one pair of mutually opposite projections 12, which are configured to slideably engage respective contoured slots 13, 14 which are respectively present on the first insert 10 and on the second insert 11.

[0030] The tilting element 8 further comprises at least one protrusion 15 facing and proximate to the surface of a recess 16 provided along the lateral surface of the second insert 11 (arranged substantially according to a chord of the circumference circumscribing the second insert 11).

[0031] The tilting element 8 is orientable, by virtue of the action of the bit 9 of the lock 4 which can be temporarily inserted into a trough 17 of the element 8 which, in the operative configuration, is facing and proximate to said bit 9.

[0032] The orientation of the tilting element 8 occurs between a first limit configuration in which the projections 12 are accommodated within a portion of the slots 13 and 14 which is proximate to a first lateral surface of the box-like body 2, and a second limit configuration, symmetrically opposite to the first limit configuration. A rotation of the actuating member 3 produces, when the tilting element 8 is in the first limit configuration, a rotation of the first 10 and second insert 11 and of the actuation means for the latches, therefore allowing the installation door to be opened.

[0033] When, instead, the tilting element 8 is in the second limit configuration, a rotation of the actuating member 3 causes a rotation of the first insert 10 and the abutment of the protrusion 15 against the surface of the recess 16 of the second insert 11, which as a consequence is therefore maintained in a fixed position: basically, in this second limit configuration an idle stroke is defined for the actuating member 3.

[0034] It is evident that by shifting the tilting element 8 from the first to the second limit configuration and vice versa it is possible to disable and enable the actuating member 3 (for example a handle or a knob or a door pull) from / for opening the door.

[0035] With reference to an embodiment of particular practical and applicative interest, the at least one tilting element 8 is constituted by a pair of contoured modules 8a and 8b which are mutually coupled, in the operative configuration, so that between them there is a single degree of freedom of mutual translation along the direction defined by an axis of symmetry arranged on the sagittal plane of said contoured modules 8a and 8b. The mutual translation will be defined according to a stroke of predefined extent.

[0036] In more detail, it should be noted that the box-like body 2 conveniently comprises a rear plate 18 configured to be juxtaposed on a face of the installation door.

[0037] The first contoured module 8a, arranged in front of the second module 8b of the pair of contoured modules 8a and 8b, and therefore arranged at a greater distance from the rear plate 18 than the distance between the second module 8b and the plate 18, comprises at least one end projection 12 (protruding with respect to both faces of the module 8a) which is configured to be inserted into respective slots 13, 14 that are facing and proximate to the contoured inserts 10 and 11.

[0038] The first module 8a further comprises at least one longitudinal slot 19, 20, which is aligned with the axis of symmetry arranged on the respective sagittal plane.

[0039] The second contoured module 8b comprises a protruding transverse shaft 21 which is configured to slideably engage a slot 20 in the first module 8a, and a second appendage 22 which is configured to slideably engage a slot 19 in the first module 8a.

[0040] Lastly, the second module 8b comprises an end trough 17 which is arranged, in the operative configuration, facing and proximate to the bit 9 of the lock 4.

[0041] The trough 17 is configured for the temporary accommodation of the bit 9, during an arc of predefined breadth of the rotation stroke of the bit 9, while the latter is rotated by the corresponding coded key 5 inserted into a specific cavity of the lock 4.

[0042] The second module 8b comprises, substantially at an end opposite to the end with the trough 17, the protruding second appendage 22 which is configured to slideably engage a second slot 19 of the first module 8a.

[0043] The slideable engagement of the appendage 22 within the slot 19 and the slideable engagement of the protruding transverse shaft 21 within the slot 20 ensures that the only reciprocal movement allowed is a translation, along a maximum stroke that corresponds to the length of the slot 19.

[0044] The first insert 10 comprises a central hole 23 for accommodating the shaft 7 of the actuating member 3 (such as a handle, a knob, a door pull and the like), and a first slot 13 constituted by a central segment 13a, parallel to a chord of the circumference that circumscribes the contour of the first insert 10, and two external segments 13b which are substantially parallel to the circumference circumscribing the contour of the first insert 10a.

[0045] The second insert 11 comprises a second slot which is substantially parallel to the delimitation surface of the recess 16 of the second insert 11: in the operative configuration of alignment of the two inserts 10 and 11, the slots 13 and 14 are facing and proximate, with the interposition of an end portion of the first module which comprises the end projection 12, which has respective mutually opposing fronts engaged in said slots 13 and 14.

[0046] The rear plate 18 comprises a seat 24 for the accommodation of the cylinder lock 4: the cylinder lock 4 is contained in the box-like body 2, with a front accommodated in the seat 24 of the rear plate. In this installation arrangement, the bit 9 of the lock 4 is arranged on a plane of arrangement parallel to the end plate 18: this plane of arrangement coincides with the plane of arrangement of the second module 8b.

[0047] The controller 1 can usefully comprise elastic means 25 configured to maintain the tilting element 8 in one of the limit configurations: the transition from the first limit configuration to the second limit configuration is thus subordinate to the forcing of such elastic means 25 by the tilting element 8 actuated rotationally by the bit 9 of the lock 4. In this manner it is possible to guard against the accidental transition from the first to the second limit configuration.

[0048] The elastic means 25 can be constituted by a lamina of elastic material (for example a metal lamina or a lamina made of composite or polymeric material) facing toward the top of the second module 8b: when a rotation is imposed on the tilting element 8 by the bit 9, a part of the module 8b (for example, but not exclusively, the protrusion 15) will come to abut against the surface of the lamina of elastic material and the transition from the first limit configuration to the second limit configuration will be possible only if the torque applied by the bit 9 is such as to enable the protrusion to elastically deform the elastic means 25.

[0049] Lastly, it should be noted that the rear plate 18, proximate to the seat 26 configured for the rotatable accommodation of the first appendage 21 of the second module 8b, comprises containment bands 27 which are configured to be facing and proximate to the lateral surfaces of the second module 8b, so defining abutment shoulders for these lateral surfaces which make it possible to guide the second module 8b during the rotation between the first and the second limit configuration of the tilting element 8.

[0050] The protection offered by the present invention also extends to a method for configuration of the external controller 1 for emergency devices of the type fully described above. This method consists first of all in identifying the direction of opening of the installation door. Once this operation is concluded, it is then possible to mount the actuating member 3 (in particular a handle, a knob, a door pull or other, equivalent component) on the box-like body 2 in conformance with the direction of opening of the door.

[0051] At this point the moveable organ of the cylinder lock 4 must be rotated using a respective key 5 in the same direction of rotation followed by the actuating member 3 in order to actuate the opening of the door, in order to configure the controller 1 to open the door from outside solely through the movement of the actuating member 3.

[0052] It should be noted that the method according to the invention also comprises a step of disabling the actuating member 3 which consists in rotating the moveable organ of the cylinder lock 4 using the respective key 5 in the opposite direction of rotation to that followed by the actuating member 3 in order to actuate the opening of the door. After executing this operation, the movements of the actuating member will be idle and will not be transmitted to the actuation means for the latches of the emergency opening device (therefore it will no longer be possible to open the door leaf from the outside).

[0053] Basically therefore, through the rotations of the key 5 in the lock 4 (which produce rotations of the bit 9 which engages the trough 17 and makes the tilting element 8 rotate from the first to the second limit configuration) it is possible to enable or disable the actuating member 3 when the controller has already been installed, while, during its installation it is possible to adapt the controller 1 to the installation door, by mounting the actuating member 3 as a function of the direction of opening of the door and configuring the controller to enable or disable the actuating member in this mounted condition.

[0054] Advantageously the present invention solves the above-mentioned problems by providing an external controller 1 for emergency devices that makes it possible to enable and disable the handle 3 by means of the cylinder lock 4 in a simple manner: as shown, in fact, enabling and disabling the handle 3 is made possible simply through a rotation of the key 5 in the lock 4.

[0055] Conveniently the controller 1 according to the invention offers reduced space occupation, since the components comprised inside the box-like body 2 have very slender thicknesses.

[0056] Advantageously the controller 1 according to the invention is constituted by components that are simple and compact, therefore generally not subject to malfunctions and breakage.

[0057] Profitably the controller 1 according to the invention allows the arrangement of the handle 3 to be inverted, so as to be adapted to doors that rotate clockwise and anticlockwise, in a simple manner, i.e. simply by acting on the rotation of the moveable organ of the lock 4 imposed by the key 5.

[0058] Usefully the controller 1 according to the invention allows the arrangement of the handle 3 to be inverted, so as to be adapted to doors that rotate clockwise and anticlockwise, without the need for tools (as already explained it is sufficient to use the key 5).

[0059] Positively the controller 1 according to the invention allows the arrangement of the handle 3 to be inverted, so as to be adapted to doors that rotate clockwise and anticlockwise, even by operators with no specialist skills.

[0060] Positively the controller 1 according to the invention is relatively easily and practically implemented and is of low cost: such characteristics make the controller 1 according to the invention an innovation that is safe in use.

[0061] The invention thus conceived is susceptible of numerous modifications and variations, all of which are within the scope of the appended claims. Moreover, all the details may be substituted by other, technically equivalent elements.

[0062] In the embodiments illustrated, individual characteristics shown in relation to specific examples may in reality be interchanged with other, different characteristics, existing in other embodiments.

[0063] In practice, the materials employed, as well as the dimensions, may be any according to requirements and to the state of the art.

[0064] Where the technical features mentioned in any claim are followed by reference numerals and / or signs, those reference numerals and / or signs have been included for the sole purpose of increasing the intelligibility of the claims and accordingly, such reference numerals and / or signs do not have any limiting effect on the interpretation of each element identified by way of example by such reference numerals and / or signs.
