Definitions

  • the present invention relates generally to the field of closures of openings or doors, in particular handle systems.
  • the cremone bolt comprises a generally vertical bar rigidly secured to a rotating arm, this bar being for example welded or screwed to a first part of the rotating arm.
  • the opening of the rotating arm thus causes the vertical bar and bolts it carries to pivot in rotation, located, for example, at the top and bottom of the door equipped with such an arrangement, to allow it to be opened.
  • the invention also applies to dry-body trucks and to handle systems for fixed or mobile installations, such as containers or shelters.
  • a cremone handle of the above type allows you to open the door to which it is attached with one hand and in a single movement.
  • the motor (actuator 34) is a linear motor and the mechanism for transmitting the motion from the motor to the rotating cam, with several lever arms and a long straight rod connecting the cam to the arms, is complex and relatively long in length.
  • the actuator has a large volume compared to the rest of the handle (rotating arm and base).
  • the locking and unlocking mechanism is enclosed in a housing, one part of which (referenced 14) is arranged laterally next to the base of the handle and another part (referenced 15) below it.
  • the motorized opening and closing solution proposed in the document EP 2921956 means that the cremone handle has a very large overall size and is very different, in size and appearance, from a non-motorized "classic" handle (see for example the models of the type “ 16 UL-R “ and “ 16 UL-X “ in the same range), so that the range of handles is not homogeneous.
  • changing a handle of this type for a classic handle can be complicated, for example if the fixing system of the remote-controlled handle on the truck door is different from that of a standard handle.
  • cremone handle cannot be surface-mounted on a truck door and must necessarily be embedded in the thickness of this door, typically between 45 and 100 millimeters.
  • the other part of the housing located under the base of the handle therefore penetrates deeply into this panel and can then create a thermal bridge between the internal face of the truck door which is exposed to the cold and its external face which can be exposed to high temperatures, all the more so since the base and the housing are often made of metal or steel which are good thermal conductors.
  • the present invention provides a motorized cremone handle which resembles a handle standard, which can be mounted on a truck door as a surface or recess, and which limits the risk of thermal bridging after installation.
  • the invention proposes a cremone handle as defined in claim 1, in which said motor is a rotary motor about a motor axis and said transmission system is formed of a worm screw (48) coupled to a shaft of said motor and of teeth present on a cylindrical external surface of said cam and coming to mesh with said worm screw.
  • the handle of the invention can be integrated into the arm, the handle no longer has any excess thickness under the base and the risk of a hot spot after mounting on a refrigerated truck door is reduced.
  • the handle of the invention can be surface-mounted or recessed on the truck door.
  • a cremone handle 1 is shown according to a preferred embodiment of the invention, the handle 1 being respectively in a closed position (case of the figure 1 ) and in an open position (case of the figure 2 ).
  • This handle 1 is intended to equip a truck 2 as shown in the figure 3 .
  • This truck has several doors 3, here three in number: two rear doors and one side door.
  • Each door 3 is provided, here on its external face 4, with a handle 1 of the invention.
  • the handle 1 comprises a base 5 and a rotating arm 6.
  • This base 5 is here in the form of a “bowl” for embedding the handle 1 in the external face 4 of each door 3 of the truck 2.
  • the base 5 comprises fixing holes 7 on a rim 8 located at the periphery of the base 5.
  • the base 5 is generally made of metal material, for example steel, and also comprises a bottom 9 in the form of a solid plate but here leaving an opening 10 allowing the opening of the handle 1 from the inside of the truck 2 (there is in practice a cylindrical hole under one of the references 33, this hole being barely visible on the figure 2 ).
  • the rotating arm 6 comprises a first part 11 which is a part mounted so as to be able to rotate on the base 5 around a handle axis A1.
  • This first part 11 is intended to be rigidly secured to a cremone bar (not shown) to rotate this cremone bar when the rotating arm 6 is actuated by a user of the handle 1.
  • the rotating arm 6 rotates relative to the base 5 around the handle axis A1 between a closed position (case of the figure 1 ) and an opening position (case of the figure 2 ).
  • the rotating arm 6 in the open position here forms an angle of approximately 90° with the base 5 and its bottom 9.
  • the first part 11 of the rotating arm 6 has a cylindrical barrel 12 of revolution around the handle axis A1, this cylindrical barrel 12 forming a hinge which comes to articulate in rotation with the base 5, and more precisely with a side wall 13 of the base 5.
  • This cylindrical barrel 12 of the first end 11 is intended to accommodate the cremone bar of an opening and closing system (not visible on the figure 3 ) of a door 3 of the truck 2.
  • This bar is generally vertical and, in the case of a handle 1 to be recessed, located inside the truck 2, on the side of the internal face of the door 3.
  • the bar is made rigidly integral with the rotating arm 6, for example by means of pins 14 inserted through the cylindrical barrel 12 (see figure 1 ) in the vertical bar of the cremone bolt.
  • the bar can also be welded, screwed or riveted to the first part of the rotating arm.
  • the rotating arm 6 of the handle 1 also has a second part 15 forming a lever that the user of the handle 1 can take by hand to rotate, by applying a mechanical torque to the handle axis A1, the first part 11 and turn the rotating arm 6.
  • This lever 15 is pivotally mounted relative to the first part 11 of the rotating arm 6 around a lever axis A2 (see figure 2 ), approximately parallel to the handle axis A1. This is visible on the figure 4 where a notch 17 (area surrounded by dotted lines) appears between the first part 11 of the rotating arm 6 and the lever 15.
  • the lever 15 is fixed to a rectilinear rod 22 extending longitudinally along the lever axis A2.
  • This rectilinear rod 22 is pivotally articulated around its two ends with the first part 11 of the rotating arm 6, and more precisely at the level of two wings 23, 24 separated from the first part 11 which extend from opposite ends of the cylindrical barrel 12.
  • the two wings 23, 24 and the cylindrical barrel thus form a U-shaped arrangement.
  • the straight rod can be rigidly secured to the two wings of the first part, the lever then pivoting around this straight rod.
  • the lever 15 of the rotating arm 6 extends on the one hand from the lever axis A2 towards the handle axis A1, that is to say from the straight rod 22 towards the cylindrical barrel 12 (not visible in the figures), in an arch 25.
  • This arch 25 here has a rectilinear portion 26 (see figures 6 And 8 ) which is parallel to the lever axis A2. It also has two curved branches 27, 28 joining the articulation of the lever 15 at the ends of the straight bar 22 to the straight portion 26 of the arch 15.
  • the lever 15 extends, in the opposite direction from the lever axis A2, that is to say from the rectilinear rod 22 axially outwards, into a handle 16 for actuating the lever 15 having a shape adapted for its manual gripping by the user of the handle 1.
  • this lever 16 When the rotating arm is in the closed position (case of the figure 1 ), this lever 16 is intended to be pulled by the user to, initially, pivot the lever 15 around its lever axis A2 (case of the figure 4 with the release 17) and allow, if the handle 1 is unlocked, the release (i.e. the unblocking) of the rotating arm 6.
  • the kinematics of this movement and its mechanism will be explained in more detail below. If, in a second step, the user continues to exert traction on the lever 16, then the rotating arm 6 is carried in rotation around the handle axis 1 then allowing the opening of the handle 1. This movement will also be described in more detail below.
  • the rotating arm 6 also has two protective covers 18, 19.
  • the first protective cover 18 hides, on the one hand, a device for locking and unlocking the handle 1 and a key lock which will be described in the remainder of the description with reference to the Figures 5 to 8 And 12 has 14 and, on the other hand, a padlock locking arrangement, well known in the field.
  • the second cover 19 hides an arrangement of parts 20, 21 in the closed position of the handle 1 which will also be described in the remainder of the description with reference to: Figures 5 to 14 .
  • These protective covers 18, 19 not only provide a pleasant aesthetic appearance but also prevent water or dust from entering the mechanical or electronic elements they protect.
  • the protective cover 18 is optional.
  • Handle 1 also has a hook 21 (see figure 2 for example) which is adapted, in the closed position, to block or unlock the rotation of the first part 11 of the rotating arm 6 around the handle axis A1.
  • This hook 21 is mounted mobile in rotation on the base 5 around a hook axis A3 (see figure 2 ).
  • This hook axis A3 is substantially parallel to the plane of the bottom 9 of the base 5 and parallel to the handle axis A1 and to the lever axis A2.
  • the hook 21 and its hook axis A3 are in fact here mounted on a substantially flat bottom plate 30, for example made of sheet metal, and more precisely at the level of small walls 31 (in the figures where they are referenced only one of the walls is visible) rising perpendicularly from the plane of the plate 30.
  • This plate 30 is intended to be fixed on the bottom 9 of the base 5, for example by welding or screwing.
  • the hook axis A3 therefore comes here to articulate with the base 5 at the level of these walls 31 of the plate 30.
  • the hook 21 can switch between two positions: a retaining position, illustrated in the Figures 5 to 10 , and a release position, illustrated in the figure 2 with handle 1 open and on the figure 11 .
  • the hook 21 is here a substantially cylindrical part of complex section. It should be noted, however, that the hook 21 is not of revolution around the hook axis A3.
  • the hook 21 here comprises a cylindrical groove 29 which is of substantially “C”-shaped section, the opening of the “C” being directed outwards, that is to say in a direction which moves away from the handle axis A1.
  • This groove 29 here extends rectilinearly along an axis parallel to the hook axis A3.
  • the groove 29 is shaped so that, in the closed position (see Figures 5 to 8 ), accommodate or “bite” a central portion of the rod 22 fixed at its two ends on the wings 23, 24 of the first part 11 of the rotating arm 6.
  • the size of the groove 29 is therefore preferably slightly greater than the size of the rod 22 of the rotating arm 6.
  • the groove 29 has an orientation (direction of the opening of the “C” of the groove section) which is substantially parallel to the bottom 9 of the base 5 and which prevents the straight rod 22 from coming out of the groove 29. Since the straight rod 22 is integral with the first part 11 of the rotating arm 6, this first part 11 is blocked in rotation, even if the user pulls on the actuating lever 16 of the lever 15 to move the rotating arm 6 away from the base 5 (i.e. in a direction substantially perpendicular to the bottom 9 of the base 5). In the closed position, the rotating arm 6 is therefore retained by the hook 21 when the latter is in its retaining position.
  • the position of the hook 21 determines whether the handle 1 can move into the open position (hook 21 in the release position) or whether it is forced to remain in the closed position (hook 21 in the retaining position).
  • the handle 1 also includes a locking and unlocking mechanism which, in the closed position, will act on the hook 21 to prevent (handle 1 locked) or allow (handle 1 unlocked) the hook 21 to tilt from its retaining position to its release position (see above).
  • This locking and unlocking mechanism comprises a blocking part 20 and a motorized device that can be controlled remotely (see in particular Figures 15 to 19 ) to activate or deactivate the blocking part (see explanations below).
  • this blocking part 20 is mounted mobile in rotation on the base 5, around a blocking axis A4 which is parallel to the hook axis A3, and therefore also to the plane of the bottom 9 of the base 5.
  • the blocking part 20 is more precisely mounted in pivot connection with the plate 30 fixed on the bottom 9 of the base 5, at the level of the walls 31 on which the hook axis A3 is also articulated.
  • the blocking part 20 can be rotated (we will see how later) between two extreme positions, at know a blocking position (see for example figures 5 , 6 And 9 ) and an unlocking position (see for example figures 7 , 8 And 10 ).
  • the blocking part 20 is mounted on the blocking axis A4 with a torsion spring 32 which is adapted to return the blocking part 20 to its blocking position relative to the base 5.
  • the blocking position is therefore the resting (or default) position of the blocking part 20, independently of the position of the hook 21 (see explanations below).
  • the blocking part 20 of the locking and unlocking mechanism here comprises two tabs 33 which are eccentric relative to the blocking axis A4 and which have flat surfaces 34.
  • the blocking piece could have only one leg, or more than two legs with flat surfaces.
  • the flat surfaces 34 are substantially parallel to the base 5, and more precisely to the bottom 9 or to the plate 30 on which the blocking part 20 is mounted.
  • the blocking part 20 is configured to, in its blocking position, prevent the hook 21 from tilting from its retaining position and to, in its unlocking position, allow the hook 21 to tilt into its release position.
  • the blocking part 20 and the hook 21 have, on each side (only one side is visible in the figures) close to the walls 31, cross sections ( i.e. perpendicular to the axes A3 and A4) with respective profiles 35, 36 having particular and “complementary” shapes, in the sense that these profiles 35, 36 are shaped to cooperate together during the movement of the blocking part 20 and the hook 21.
  • the spacing between the hook axis A3 and the blocking axis A4 is selected so that the profile 35 of the blocking part 20 and the profile 36 of the hook 21 can be in contact during the movement.
  • the blocking part 20 can, on the other hand, rotate around its blocking axis A4 (for example by pressing on its legs 34), its profile 35 rubbing on the profile 36 of the hook 21, without making it rotate around its hook axis A3.
  • the locking part 20 is automatically returned to its locking position, then maintaining, thanks to the profile 36 of the hook 21, the latter in its release position.
  • the motorized device 39 comprises, seen from the outside, a housing 40, from which emerges a pair of electric wires 41 (conductors and sheaths). These electric wires 41 are intended to be connected at their ends 41A to an external source of electric current (not shown) for the power supply of the various components of the motorized device 39 (see below).
  • the power supply is preferably in direct current and at low voltage, for example from an electric line drawn from the battery of the truck 2.
  • this housing 40 is formed of a cover 43, substantially parallelepipedal, hollow and a base 42 in the form of a substantially flat plate having contours of a shape corresponding to the cover 43.
  • the base 42 is assembled and fixed to the cover 43 by means of assembly screws 44, 45 (the screw 45 has a particular function which will be described in more detail later) which are placed in threaded barrels (not visible in the figure) formed inside the cover 43.
  • the base 42 and the cover 43 can be made of hard plastic material, for example by molding.
  • the housing 40 also has an opening 46 made at the level of the cover 43, the usefulness of which will become apparent later.
  • said housing 40 is assembled with removable fixing means on a fixing support 82 ( figures 6 And 8 ) rigidly secured to the rotating arm 6, and more precisely here on its first part 11.
  • the housing 40 comprises, at the level of its cover 43, a projection 83 (see Figures 15 to 19 ) with two cylindrical wells 85 intended to accommodate two assembly screws 84 which are screwed into hexagonal assembly nuts 86 held and locked in position in hexagonal cavities 87 formed in a part of the fixing support 82 covering the projection 83 of the housing 40.
  • This system for assembling the housing 40 of the motorized device 39 has the advantage of allowing the installation of the handle 1 on the cremone bar without risk. to affect the motorized device 39 and also to allow its replacement if necessary, for example if the motorized device breaks down.
  • the motorized device 39 comprises two sets of components which “align” along two axes of rotation A5, A6 perpendicular to each other.
  • the first set mainly comprises a rotary motor 47 and a worm screw 48 which are coaxial along the motor axis A5.
  • This motor 47 is of the “ micro-motor” type and, for its integration into the rotating arm 6, has very small dimensions, here with a diameter of approximately 13 millimeters and a length of approximately 57 millimeters. Due to this very small size, the engine torque developed by the motor 47 is limited.
  • the motor 47 is electrically powered by the pair of electrical wires 41 which connect to electrical contacts 50 of the motor 47. Thus powered, the motor 47 drives a motor shaft 51 in rotation around the motor axis A5.
  • the motor axis A5 is advantageously located in a plane parallel to the plane of the first part 11 of the rotating arm 6 defined for example by the handle axis A1 and the two wings 23, 24 of the first part 11. We will see the interest of this orientation later.
  • the shaft 51 is adapted to be inserted into a cylindrical hole 52 (see figures 16 And 18 ) drilled coaxially in the worm screw 48, from a first end of the worm screw 48.
  • the depth of this cylindrical hole 52 is preferably slightly greater than the length of the rotating shaft 51 of the motor 47.
  • the shaft 51 has a flat 53 over its entire axial length (see figure 19 ) in order to be secured to the worm screw 48 by means of the clamping screw 54 which passes axially through the worm screw 48 to come to bear on this flat 53.
  • the motor 47 of the motorized device 39 is coupled to the worm screw 48, so that the mechanical torque of the motor 47 (applied to the motor axis A5) is fully transferred to the worm screw 48.
  • the motor 47 drives the worm screw 48 in rotation, which then rotates around the motor axis A5.
  • the washer 55 is inserted on the shaft 51 between the motor 47 and the first end of the worm screw 48 (cylindrical hole 52 side) while the ball bearing 56 is located on the other side, to surround the second end of the worm screw 48 which is in pivot connection with the ball bearing 56.
  • the second set of components of the motorized device 39 here comprises a cam 49, a nut 59 and the screw 45 which are coaxial along the cam axis A6 (see figure 19 ).
  • This cam 49 which is housed in the housing 40, here has substantially the shape of a quarter cylinder with a bored central barrel 60 which is cylindrical in revolution and which precisely defines the cam axis A6.
  • this central barrel 60 accommodates, on one side (here from the top in the case of the figure 19 ), a cylindrical part 61 of the nut 59 which is internally tapped, and, on the other side, the threaded part 62 of the screw 45 which will screw inside the cylindrical part 61 of the nut 59.
  • the screwing of the screw 45 into this cylindrical part 61 is made possible by the fact that the nut 59 has a hexagonal head 63 which, when the housing 40 is closed, is blocked in rotation by its reception in a corresponding hexagonal hole 64 formed in the cover 43 of the housing 40.
  • the screw 45 allows not only the assembly of the base 42 with the cover 43 but also the rotational mounting of the cam 49 along the cam axis A6 around the cylindrical part 61 of the nut 59.
  • the cam 49 of the motorized device 39 is formed with a curved lug 65 which extends the main cylindrical part of the cam 49.
  • this lug 65 comprises at its end a lug head 66.
  • this lug 65 of the cam 49 is adapted to project through the opening 46 formed in the cover 43 of the housing 40 (closed by the base 42 in its lower part in the figure).
  • cam 49 can be driven in rotation along cam axis A6 thanks to motor 47 rotating along motor axis A5 which, it will be recalled, is perpendicular to cam axis A6.
  • the cam 49 has, on an external face 67 (see figure 19 ) cylindrical of its main part in the shape of a quarter wheel, teeth 68 which mesh with a thread 69 of the worm screw 48.
  • this arrangement of the teeth 68 and the thread 69 forms a gear making it possible to transform, by sliding the teeth 68 on the thread 69, the rotational movement of the shaft 51 of the motor 47 around the motor axis A5 into another rotational movement of the cam 49 around the cam axis A6 perpendicular to the motor axis A5.
  • the cam 49 also rotates in an opposite direction (clockwise in the figures) to retract and return the lug 65 inside the housing 40. We then return to the initial configuration illustrated in the figures 15 And 16 .
  • the lug 65 can move continuously between its retracted position and its deployed position.
  • the motorized device 39 can be entirely integrated inside the rotating arm 6, here in its first part 11, under the volume of a wing 23.
  • the locking and unlocking mechanism also comprises a movable carriage 70 which is mounted so as to slide on the arch 25 of the lever 15.
  • the mobile carriage 70 slides along a guide rail 71 housed inside the rectilinear part 26 of the arch 25, between its two curved portions 27, 28.
  • This guide rail 71 is here rectilinear with a circular cross-section, but it could, as a variant, be curvilinear or of non-circular cross-section. It is advantageously made of rigid material, for example metal or steel, preferably stainless steel.
  • the motorized device 39 is configured to slide the mobile carriage 70 along the arch 25 between two extreme positions on the guide rail 71: a locking position (case of figures 5 , 6 And 12 ) and an unlocking position (case of figures 7 , 8 , 13 And 14 ).
  • a locking position case of figures 5 , 6 And 12
  • an unlocking position case of figures 7 , 8 , 13 And 14 .
  • the mobile carriage 70 comprises (see Figures 12 to 14 ) a first stop 72.
  • This first stop 72 has a substantially flat support surface, perpendicular to the direction of the guide rail 71 and oriented towards the outside of the mobile carriage 70.
  • the housing 40 of the motorized device 39 is arranged inside the rotating arm 6 such that its opening 46 substantially faces this first stop 72 of the mobile carriage 70, when the mobile carriage is in the locking position (see for example figure 12 ).
  • the lug head 66 comes, when the lug 65 of the cam 49 is in the retracted position (see above), opposite the first stop 72 of the movable carriage 70, and more precisely with its support surface.
  • the lug head 66 is even in contact with the first stop 72, but without necessarily exerting a force on its support surface.
  • the arrangement of the housing and the movable carriage within the rotating arm could be made so that, in the retracted position of the lug and in the locking position of the movable carriage, a space exists between the lug head and the bearing surface of the first stop.
  • the lug head 46 resting on the first stop 72 will “push” the mobile carriage 70 along the guide rail 71 to take it to its unlocked position.
  • the “thrust” of the mobile carriage 70 by the lug 65 of the cam 49 is made possible by the fact that the movement of the lug head 66 can be assimilated (see explanations above) to a translation substantially parallel to the axis of the guide rail 71 and that the support surface of the first stop 72 of the mobile carriage 70 is perpendicular to the axis of the guide rail 71.
  • the lug head 66 has a curved profile which facilitates the sliding of the support point between the lug head 66 and the support surface of the first stop 72 and thus avoids jolts during this push.
  • a compression spring 73 is also provided against which the movement of the movable carriage 70 takes place.
  • This compression spring 73 is here wound around the guide rail 71 of the arch 25 with one of its ends which comes into abutment on a stop element of the arch 25 (not visible in the figures) and the other of its ends which comes into abutment on a leg 74 (see in particular figure 2 ) substantially in the shape of a quarter of a disc centered on the axis of the guide rail 71.
  • the compression spring 73 thus allows the movable carriage 70 to return to its locking position when the lug 65 returns to its retracted position, following the movement of the cam 49 actuated by the motor 47 (see explanations above).
  • the mobile carriage 70 is arranged in the rotating arm 6 so that, in its unlocked position (case of the figure 8 ), activate the blocking part 20 to move it into its unlocking position, by means of the pivoting of the lever 15 by the user pulling on the handle 16 and the lowering (bringing closer to the base 5, see above) of the arch 25 which carries the mobile carriage 70 in its movement.
  • the mobile carriage 70 comprises activation means 75 which, in the locking position, are offset relative to the blocking part 20, such that these activation means 75 are inoperative on the blocking part 20, and which, in the unlocking position, are arranged opposite the blocking part 20.
  • the activation means are formed (see figures 2 , 6 And 8 ) of two push buttons 75, flat and substantially rectangular, extending parallel to the guide rail 71 and perpendicular to the legs 74 present on the mobile carriage 70.
  • the push buttons 75 are configured to, in the unlocking position of the mobile carriage 70, press on the flat surfaces 34 of the two legs 33 of the blocking part 20 so as to rotate it around its blocking axis A4 towards its unlocking position, and thus allow the hook 21 to tilt into the release position (see explanations above).
  • the locking and unlocking mechanism of the handle 1 also comprises a key lock 76 which can be locked or unlocked by the user by means of a key (not shown).
  • a key lock 76 in addition to the motorized device makes it possible to ensure that the handle 1 can be locked or unlocked by the user, even in the event of a malfunction of the motorized device 39, for example due to a breakdown of the motor 47, a fault in the electrical supply, or a seized gear between the worm screw 48 and the cam 49.
  • this key lock 76 firstly comprises a cylindrical barrel 77 in which the lock key is inserted and turned ( via the keyhole 78) for locking or unlocking the key lock 76.
  • the key lock 76 also here includes a bolt 79 of oblong and substantially parallelepipedal shape (see also Figures 12 to 14 ), which is movable by sliding through the barrel 77 in a direction parallel to the guide rail 71 by virtue of the rotation of the lock key in the barrel 77.
  • the bolt 79 occupies a position centered relative to the axis of the barrel 77 (see figure 12 For example).
  • This sliding bolt 79 has a curved end 80 (see figures 6 And 8 ), approximately at right angles, towards the entrance of the barrel 77 and the keyhole 78.
  • the shapes and dimensions of the bolt 79 and the movable carriage 70, as well as the relative arrangement of the key lock 76 and the movable carriage 70 in the rotating arm 6 are determined such that, in the locking position (see figure 12 , the curved end 80 of the bolt 79 is, at least in part, opposite a second stop 81 of the movable carriage 70, and more precisely a support surface of this second stop 81 which is substantially flat, perpendicular to the axis of the guide rail 71 and oriented towards the “inside” of the movable carriage 70.
  • the handle 1 comprises both a motorized device 39 in combination with a key lock 76 as is the case here, it can advantageously be provided that the barrel 77 of the key lock 76 is itself mounted on the fixing support 82.
