Definitions

  • the present invention generally relates to the field of opening or door closures, in particular handle systems.
  • the cremone bolt comprises a bar that is generally vertical and rigidly attached to a rotating arm, this bar being for example welded or screwed to a first part of the rotating arm.
  • the opening of the rotary arm thus rotates the vertical bar as well as the bolts which it carries located, for example, at the top and bottom of the door equipped with such an arrangement, to allow its opening.
  • the invention also applies to dry body trucks and handle systems for fixed or mobile installations, such as containers or “shelters”.
  • a cremone handle of the type above makes it possible in particular to open the door on which it is fixed with one hand and with a single movement.
  • the motor (actuator 34) is a linear motor and the mechanism for transmitting the movement of 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 extended 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, a part of which (referenced 14) is arranged laterally next to the base of the handle and another part (referenced 15) under it.
  • the motorized opening and closing solution proposed in the document EP 2921956 results in the cremone handle having a very large overall footprint and is very different, in size and appearance, from a “classic” non-motorized handle (see for example the “16 UL-R” and “16 UL-R” type models ) . 16 UL-X” in the same range), so the range of handles is not homogeneous.
  • changing a handle of this type with a conventional 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 of the prior art cannot be installed on a truck door and must necessarily be recessed 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 door of the truck which is exposed to the cold and its external face which can be exposed to high temperatures, especially since the base and the housing are often made of metal or steel which are good thermal conductors.
  • the present invention proposes a motorized cremone handle which resembles a handle standard, which can be mounted on a truck door either surface-mounted or recessed, and which limits the risk of thermal bridges after assembly.
  • a cremone handle as defined in claim 1, in which said motor is a rotary motor around a motor axis and said transmission system is formed of a worm screw ( 48) coupled to a shaft of said motor and teeth present on a cylindrical external surface of said cam and engaging said endless screw.
  • the handle no longer has any extra 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 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 a 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 shape of a “bowl” for embedding the handle 1 in the external face 4 of each door 3 of the truck 2.
  • the base 5 includes fixing holes 7 on a rim 8 located at the periphery of the base 5.
  • the base 5 is generally made of metallic material, for example steel, and also includes 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 part mounted movable in rotation 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 rotary 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 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 rotary arm 6 has a cylindrical barrel 12 of revolution around the handle axis A1, this cylindrical barrel 12 forming a hinge which is articulated in rotation with the base 5, and more precisely with a wall side 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 recessed handle 1, 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.
  • 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 which the user of the handle 1 can take by hand to cause it to rotate, by applying a mechanical torque to the handle axis A1 , the first part 11 and rotate the rotating arm 6.
  • This lever 15 is pivotally mounted relative to the first part 11 of the rotary arm 6 around a lever axis A2 (see figure 2 ), substantially parallel to the handle axis A1. This is visible on the Figure 4 where a detachment 17 (area circled with the 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 pivots around its two ends with the first part 11 of the rotary 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 shaped arrangement of U.
  • the rectilinear rod can be rigidly secured to the two wings of the first part, the lever then pivoting around this rectilinear rod.
  • the lever 15 of the rotary arm 6 extends on the one hand from the lever axis A2 towards the handle axis A1, that is to say from the rectilinear 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 level of the ends of the rectilinear bar 22 to the rectilinear 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 lever 16 for actuating the lever 15 having a shape adapted for 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, rotate 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 (ie the unlocking) 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 rotated 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 includes 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 to 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 the figures 5 to 14 .
  • protective covers 18, 19 make it possible not only to present a pleasant aesthetic appearance but also to prevent water or dust from getting into the the mechanical or electronic elements they protect.
  • the protective cover 18 is optional.
  • the handle 1 also includes 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 rotary arm 6 around the handle axis A1.
  • This hook 21 is mounted movable 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 mounted here 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 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 on the figures 5 to 10 , and a release position, illustrated on the figure 2 with handle 1 open and on the Figure 11 .
  • the hook 21 In its retaining position, the hook 21 retains the rotating arm 6 of the handle 1 in the closed position. On the contrary, in its release position, the hook 21 is adapted to no longer retain the rotating arm 6 and therefore to release it to possibly allow its rotation (by pulling on the lever 16) and passage into the open position.
  • the hook 21 is here a substantially cylindrical part of complex section. Note, however, that the hook 21 does not rotate 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 extends here rectilinearly along an axis parallel to the hook axis A3.
  • the groove 29 is shaped for, 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 rectilinear rod 22 from leaving the groove 29.
  • the rectilinear 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 actuation handle 16 of the lever 15 to move the rotating arm 6 away from the base 5 (that is to say in a direction substantially perpendicular to the bottom 9 of the base 5).
  • the rotating arm 6 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 to the open position (hook 21 in the release position) or if it is condemned 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 authorize (handle 1 unlocked) the tilting of the hook 21 from its position. retained in 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 to move in rotation on the base 5, around a blocking axis A4 which is parallel to the hook axis A3, and therefore also to the bottom plane 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 is also articulated A3.
  • 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 position at rest (or by default) 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 with respect to the blocking axis A4 and which have flat surfaces 34.
  • the blocking part could have only one tab, or more than two tabs having 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 tilting of the hook 21 from its retaining position and to, in its unlocking position, authorize the tilting of the hook 21 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 ( ie perpendicular to the axes A3 and A4) with profiles 35, 36 respectively 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 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 of its hook axis A3.
  • the locking part 20 is automatically returned to its locking position, now, thanks to the profile 36 of the hook 21, the latter in its release position .
  • the user will only have to press the lever 16 (in the direction of the base 5) so that the straight rod 22 presses in turn on the ramp 37 and so that the hook 21 switches to the holding position, the rectilinear rod 22 then slides on the ramp 37 and comes to be housed in the groove 29.
  • the handle 1 is then in the closed position (case of the figure 1 ) and the rotating arm 6 is retained by the hook 21 near the base 5 and can no longer be released and rotated, unless acting on the blocking part 20 (see above).
  • the motorized device 39 comprises, seen from the outside, a housing 40, from which a pair of electrical wires 41 (conductors and sheaths) emerge. These electrical wires 41 are intended to be connected at their ends 41A to an external source of electrical current (not shown) for supplying current to the various components of the motorized device 39 (see below).
  • the electrical supply is preferably direct current and low voltage, for example from an electrical line drawn from the battery of truck 2.
  • this housing 40 is formed of a cover 43, substantially parallelepiped, hollow and a base 42 in the form of a substantially flat plate having contours of shape corresponding to the cover 43.
  • the base 42 is assembled and is fix 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 in the inside the cover 43.
  • the base 42 and the cover 43 can be made of hard plastic, 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 includes, 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 box 40.
  • This assembly system of 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 assembly 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 engine 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 rotary 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 plugged into a cylindrical hole 52 (see figures 16 And 18 ) drilled coaxially in the endless screw 48, from a first end of the endless 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 endless screw 48 by means of the clamping screw 54 which passes axially through the endless screw 48 to come to bear on this flat 53.
  • the motor 47 of the motorized device 39 is coupled to the endless screw 48, so that the mechanical torque of the motor 47 (applied to the motor axis A5) is fully transferred to the endless screw 48.
  • the motor 47 rotates the endless screw 48 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 endless screw 48 (cylindrical hole 52 side) while the ball bearing 56 is located on the other side, to surround the second end of the endless 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 of a cylinder with a bored central barrel 60 which is cylindrical of 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 threaded, 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.
  • Screwing 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 from rotating by its reception in a hexagonal hole 64 corresponding 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 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).
  • 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 endless screw 48.
  • this arrangement of the teeth 68 and the thread 69 forms a gear making it possible to transform, by sliding of the teeth 68 on the thread 69, the rotational movement of the shaft 51 of the motor 47 around the motor axis A5 into a further rotational movement of cam 49 around cam axis A6 perpendicular to motor axis A5.
  • 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 includes a mobile carriage 70 which is mounted 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 straight circular section, but it could, alternatively, be curvilinear or of non-circular 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 bearing surface, perpendicular to the direction of the guide rail 71 and oriented towards the outside of the mobile carriage 70.
  • housing 40 of the motorized device 39 is arranged inside the rotating arm 6 such that its opening 46 faces substantially 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), facing the first stop 72 of the mobile carriage 70, and more precisely with its surface of 'support.
  • the lug head 66 is even in contact with the first stop 72, but without necessarily exerting a force on its bearing surface.
  • the arrangement of the housing and the movable carriage inside the rotary 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 "push" 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 bearing 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 convex profile which facilitates the sliding of the point of support between the lug head 66 and the bearing surface of the first stop 72 and thus avoids jerks during this thrust .
  • a compression spring 73 is also provided against which the movement of the mobile 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 abuts on a stop element of the arch 25 (not visible in the figures) and the other of its ends which abuts on a leg 74 (see in particular figure 2 ) substantially in the shape of a quarter disc centered on the axis of the guide rail 71.
  • the compression spring 73 thus allows the mobile 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 the motor 47 (see explanations above).
  • the mobile carriage 70 is arranged in the rotating arm 6 so as to, in its unlocked position (case of the figure 8 ), activate the blocking part 20 to move it into its unlocking position, thanks to the pivoting of the lever 15 by pulling the user on the lever 16 and the lowering (approaching of the base 5, see below 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, so that these activation means 75 are inoperative on the blocking part 20, and which , in the unlocked position, are arranged opposite the blocking part 20.
  • the activation means are formed (see figures 2 , 6 And 8 ) two push buttons 75, planar 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 make it rotate around its blocking axis A4 towards its position of unlocking, 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 includes 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 ensures 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 power supply fault, or a gear between endless screw 48 and cam 49 seized.
  • this key lock 76 firstly comprises a cylindrical barrel 77 into which the lock key is inserted and rotates ( via the keyhole 78) for locking or unlocking the key lock 76.
  • the key lock 76 also includes here a bolt 79 of oblong and substantially parallelepiped shape (see also figures 12 to 14 ), which is movable to slide through the barrel 77 in a direction parallel to the guide rail 71 thanks to the rotation of the lock key in the barrel 77.
  • the bolt 79 occupies a position centered in relation to to the barrel axis 77 (see Figure 12 For example).
  • This sliding bolt 79 has a curved end 80 (see figures 6 And 8 ), substantially 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, facing a second stop 81 of the mobile carriage 70, and more precisely a bearing 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 mobile 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.
