Definitions

  • the invention relates to keys used to loosen filters removably mounted by screwing on rigid supports, filters comprising a filter element inside a fluted hood in a bell or the like.
  • cover in the present text and in the claims which follow a cover comprising a cylindrical skirt connected to a bottom, generally curved outwards, cover for which the area of the skirt, adjacent to the bottom, is deformed so as to present a ring of longitudinal indentations distributed around said zone, these indentations being able either to be grooves or notches hollowed out towards the inside of the skirt and then making up grooves proper as well as flats delimiting a prism with a section polygonal.
  • a key comprising a rigid ring suitable for surrounding the grooved portion of the cover and having a non-circular internal contour cooperating with the grooves for the purpose of angular attachment, said ring being connected rigidly to a rigid radial handle.
  • filter assemblers of the type in question are asked to tighten them by hand to avoid the creation of significant tightening torques, resulting in an undesirable crushing of the seal provided between the filter and its support and by a attack of the receiving surfaces of said seal.
  • the object of the invention is, above all, to overcome this drawback by excluding any possibility of exerting significant tightening torques using the wrenches considered without in any way reducing the importance of the loosening torques applicable with these keys.
  • wrenches comprising a rigid annular tool suitable for surrounding the heads of the bolts and having a non-circular internal contour suitable for cooperating with these heads for the purpose of angular attachment, a rigid handle pivotally mounted on the tool, about an axis linked to this tool and parallel to that of the tool in such a way that the angular displacements of this handle are limited by bracing from its radial position or from a substantially such position, for the direction corresponding to the loosening and on the contrary remain free in the opposite direction from this position, and coding means provided on the tool so that the wrench can only overlap the heads of the bolts in the direction corresponding to the above effects.
  • the pivot axis of the handle is arranged in the middle of the length of this handle so that the lever arm available for tightening is equal to half that available for loosening, as in the key described in GB-A-1496524.
  • the keys of the kind in question according to the invention are essentially characterized in that the pivot axis of the handle on the tool is disposed in the immediate vicinity of this tool.
  • the invention includes, apart from these main provisions, certain other provisions which are preferably used at the same time and which will be more explicitly discussed below.
  • Figures 1 and 2 of this drawing show respectively in side view, portions cut axially along I-I, Figure 2 and in end view according to arrow II of Figure 1, a release key established according to the invention.
  • the key considered 1 is intended to loosen filters, such as oil filters for vehicle engines, which have been previously mounted on their supports by tightening for screwing purposes.
  • the filter is delimited on the outside by a hood 2 in the shape of a bell, hood whose cylindrical skirt 3 is hollowed out, in the vicinity of its curved bottom 4, by longitudinal grooves 5.
  • the key 1 comprises a rigid tool or ring 6 suitable for surrounding the grooved portion of the cover 2 and having, radially projecting on its internal cylindrical face, teeth 7 adapted to cooperate with the grooves 5 at ends of angular attachment of the key on the cover.
  • This key further comprises a handle or handle 8 allowing the grip and linked to the ring so as to allow the control of its rotations.
  • connection between the handle and the ring is not rigid: it is pivotally provided around an axis Y which is parallel to the X axis of the ring which is arranged in the immediate vicinity of this ring.
  • This assembly is carried out in such a way that the angular travel of the handle 8 in the direction of the arrow F corresponding to a loosening of the cover (anti-clockwise direction in FIG. 2) is limited by mechanical stop from a position " radial "or substantially” radial "of the handle, position for which the mean line of this handle is contained in the plane defined by the two axes X and Y.
  • This mechanical stop is obtained by bringing a portion of the handle against the ring 6.
  • the handle 8 comprises a rigid metal angle 9.
  • a wing 91 of this angle 9 extends perpendicularly to the axis Y, is crossed by this axis and it is mounted on an ear 10 which extends radially the ring 6 towards the outside and which is pierced with a bore 11 Y axis using a rivet 12 passing through this bore.
  • the edge, of the wing 91, disposed near the ring 6, is circularly shaped around the axis Y so as to make possible the angular displacements of the handle in the opposite direction to the arrow F, it is i.e. clockwise in Figure 2.
  • the ear 10 is housed inside the angle 9.
  • This angle is surrounded, in its portion furthest from the ring 6, by a sleeve 14 facilitating its gripping.
  • the ring 6 is extended axially by at least one bent tab 14 whose end, folded towards the X axis is suitable for covering the cover 2 and for bearing against the bottom 4 of this cover when the key is put in place on the latter.
  • This key has the following important advantage over those previously known: it can be used exclusively for loosening splined or similar filter covers and it is not not possible to use it to tighten such covers, which makes it impossible to excessively screw them during their assembly, to the benefit of their seals and the receiving areas of these seals.
