Definitions

  • the invention relates to a hooking device between a heald frame and a lever actuated by a weave mechanism.
  • the invention also relates to a loom equipped with such a device.
  • connecting devices arranged to semi-automatically ensure the hooking and unhooking of the frames with respect to levers of mechanics.
  • Such a device is known to EP-A-0 117 826 wherein an open hook is configured to cooperate with a polygonal ring, this hook being provided with two flanges forming a locking pawl of the ring. These flanges are arranged on either side of a branch of the hook on which they are articulated.
  • Each flange has a relatively small thickness and the branch on which they are articulated must also have a relatively small thickness relative to the rest of the hook and with respect to the width of the ring, to allow an alignment of these flanges with the ring. Because of the small thickness of the flanges, the contacting surfaces of these flanges and the ring are relatively small, which, given the usual vibrations in a loom, leads to premature wear of the flanges and / or the Ring. In addition, the axis of articulation of the flanges on the hook also tends to wear because of these vibrations. Furthermore, there is provided a tension spring for exerting on the flanges a force tending to bring them to a locking position of the ring.
  • the invention intends to remedy more particularly by providing an attachment device as easy as that of the state of the art and in which the risks of premature wear are substantially reduced.
  • the invention relates to a coupling device between a heald frame and a lever actuated by a weave mechanism, this device comprising a ring with a generally polygonal profile, integral with the frame or the lever, and an open hook. , provided with spans arranged to cooperate with the profile of the ring and secured to the lever or the frame, some of these spans being parallel to each other and able to ensure, by cooperation with two ring surfaces also parallel to each other, the essential the transmission of force between the lever and the heald frame, while the hook is equipped with a locking member of the ring in position engaged in the hook the bearing area of the locking member against the ring .
  • the locking member is constituted by a bolt forming a hinge pin received in a cavity formed in the thickness of the hook, this latch having a surface capable of interacting with the ring and of width substantially equal to the width of the ring.
  • the range of the lock on the polygonal ring can take place over substantially the entire width of this ring, which substantially increases the contact area with respect to known devices.
  • the fact that the latch forms a hinge pin received in a hook cavity makes it possible to dispense with the use of an attached spindle, such as a rivet, and induces efficient transmission of effort between the latch and the hook.
  • the fact that the bearing area of the lock against the ring is located substantially between the articualtion axes of the ring and the lock induces that the lock works mainly in compression, which allows it to be particularly effective.
  • the lock since most of the forces transmitted by the lever to the frame pass through the bearing surfaces and the parallel surfaces provided respectively on the hook and the ring, the lock is not permanently solicited.
  • the invention also relates to a loom equipped with a hooking device as previously described.
  • a loom is easier to use than those of the state of the art, while its maintenance is facilitated and that the life of the devices it comprises is significantly improved over that of known trades.
  • the performance of such a trade is significantly increased compared to those of the trades of the state of the art.
  • a weaving loom frame 1 is represented by its lower amount in the figures and constitutes a part of a loom M.
  • the ring 4 has a metal axis 5 crimped on the flanges 3 and 3 '.
  • the ring 4 is made by molding in self-lubricating plastic material.
  • the ring 4 is in one piece with a grease nipple 6 enabling the area of contact between the ring 4 and the axis 5 to be filled with a lubricant. Note that the ring 4 can rotate about the axis 5, so that the lubricator 6 can be arranged in the position shown in solid lines or in the position shown in phantom at the figure 1 , depending on the intended direction of cooperation with a hook.
  • the flanges 3 and 3 ' are pressed at the edges of the ring 4, so that they form zones 7 and 7' separated by a distance d greater than the distance d 0 separating the flanges 3 and 3 'in their connecting part with the bar 2.
  • the width l 4 of the ring 4 which is substantially equal to the distance d , greater than the distance d 0 which is related to the width of the head 12.
  • the ring 4 is partially engaged in two stampings 30 and 30 'respectively forming the zones 7 and 7' on the flanges 3 and 3 'and defining between them the receiving volume of the ring 4.
  • the lubricator 6 is provided with two lateral pins 61 and 61 'intended to be engaged in lateral extensions 31 and 31' of the stampings 30 and 30 '.
  • the extensions 31 and 31 ' form grooves for receiving the pins 61 and 61' facing towards the center of the volume defined between these flanges.
  • the pins 61 and 61 ' are integral with the grease nipple 6 and. the ring 4.
  • the distance d 1 between the flanges 3 and 3' is equal to the distance d and greater than the width l 1 of the grease nipple 6 at the level of the pins 61 and 61 '.
  • the pins can be moved in the width of the extensions 31 and 31 'without rubbing against the flanges, which allows a limited angular movement of the ring 4 about the geometric axis X 5 of the axis 5.
  • the grease nipple 6 could carry only one peg, the two flanges 3 and 3 'can remain identical to simplify the manufacture of the device.
  • a single pin cooperating with a single extension is sufficient to limit the angular movement of the ring 4.
  • a hook 10 is integral with or welded to a lever 11 actuated by a weave mechanism such as a dobby.
  • the hook 10 comprises a head 12 defining a housing 13 for receiving the ring 4, the housing 13 being bordered by surfaces 14 1 , 14 2 , 14 3 and 14 4 adapted to respectively engage the surfaces 4 1 , 4 2 , 4 3 and 4 4 of the edge of the ring 4.
  • the forces of movement of the frame 1 are generally perpendicular to the bearing surfaces 14 1 and 14 4 and the surfaces 4 1 and 4 4 , as represented by the movement arrows M 1 and M 2 at the figure 3 .
  • the forces of movement of the frame 1 transit, essentially, these surfaces and surfaces.
  • the ring 4 does not tend to be driven out of the housing 13.
  • the surfaces 4 1 and 4 4 can remain perpendicular to the forces of movement M 1 and M 2 , including in the case where the lever 11 has tendency to oscillate perpendicular to the vertical in the plane of figures 1 , 3 and 5 .
  • the hook 10 is also provided with a branch 15 on which is mounted a lock 16 for retaining the ring 4 in the configuration of the figure 3 .
  • the latch 16 includes a surface 161 intended to come into contact with a side surface 4 5 of the ring 4, the surface 161 having a width l substantially equal to the thickness e of the bolt 16 which is itself substantially equal to the 'thickness e ' of the metal plate in which the hook 10 is cut.
  • the width l is substantially equal, preferably slightly smaller, to the width l 4 .
  • a planar support surfaces 161 and 4 5 is possible over the area of the surface 161.
  • the latch 16 comprises a tab 162 whose end 163 has an outer section partly cylindrical, so that it can form a hinge axis in a cavity 151 formed in the thickness e 'of the branch 15 and having a partially cylindrical shape.
  • X 1 the geometric axis of the end 163 and X 2 the geometric axis of the cavity 151.
  • the X 1 and X 2 axes coincide and the end 163 forms a hinge axis on the hook 10, this axis being integral with the lock 16.
  • the latch 16 does not intervene systematically to counter the force transmission forces but mainly to ensure the relative position engaged hook and ring against vibratory movements and the possible obliquity of the hook.
  • the latch 16 is therefore not very stressed and the fact that it works in compression is very favorable mechanically to obtain effective locking of the ring 4 in the housing 13.
  • the branch 15 forms a return 152 around the cavity 151 while a slot 164 is defined between the tab 162 and a rear portion 165 of the lock 16 opposite the surface 161.
  • the geometry of the elements 152 and 164 is such that, in mounted configuration of the latch 16, the return 152 is engaged inside the slot 164.
  • the geometry of these elements limits a movement of the tilting of the latch 16 about the axes X 1 and X 2 in the opposite trigonometric direction to the figure 3 , that is to say in the direction of the arrow F 1 .
  • the lock 16 defines a housing 166 for receiving an end 171 of a compression spring 17 whose second end 172 is received in a housing 153 provided on the branch 15.
  • the housings 171 and 172 are formed in the thickness of the edges facing the elements 15 and 16.
  • the spring 17 is dimensioned so that it exerts permanence on the latch 16 a force represented by the arrow F 2 tending to tilt the latch 16 in the direction of the arrow F 1 to the figure 1 .
  • An operating member 18 is formed by a molded plastic part which essentially comprises two flanges 181, 182 connected by a cylindrical axis 183 and by a bottom web 184.
  • the actuating member is also provided with a tab 185 allowing a user to exert effort, represented by the arrow F 3 to the figure 5 , tending to tilt the latch 16 about the axes X 1 and X 2 , in the direction of the arrow F ' 1 opposite the arrow F 1 .
  • the latch 16 is provided with a housing 167 for receiving the axis 183, with possibility of rotation, while the web 184 is provided with a spout 186 intended to engage in a cavity 168 of the latch 16 facing the opposite the surface 161.
  • the member 18 When the member 18 is in place on the latch 16, its flanges 181 and 182 constitute two cheeks which isolate the volume V defined between the latch 16 and the branch 15 from the outside and in which the spring 17 and the spring 17 are arranged. axis 163.
  • the member 18 is a volume V containment element that protects the volume against pollution and, in particular, against the flocks.
  • the member 18 also makes it possible to retain inside the volume V a lubricant such as grease, such a lubricant can be put in place to facilitate the articulation of the lock 16 on the branch 15.
  • the upper surface 169 of the lock 16 which connects the surface 161 to the portion 165 is generally aligned with the surface 14 4 , which facilitates the sliding of the ring 4 which bears on this surface 169.
  • the invention has the particular advantage that the lock 16, which has a thickness e substantially equal to the thickness e 'of the rest of the hook 10, is articulated on the hook without the use of a rivet may wear prematurely.
  • the mounting mode of the member 18 on the lock 16 and the lock 16 on the branch 15 allows for easy disassembly of these elements.
  • the invention has been shown with a substantially hexagonal section ring.
  • the ring may be octagonal and more generally have any polygonal shape, comprising two parallel surfaces for the transmission of force between the lever and the ring, the other parts of the profile of the ring being able to be flat or curved, the geometry of the hook being then adapted.
  • the invention has been shown with the ring integral with a heald frame while the hook is secured to a drive lever.
  • a reverse structure may be envisaged in which the ring is secured to a lever while the hook is secured to a heald frame.
