  • the lid can be lifted by the key being restrained by the entire lateral surface of the socket, and not simply by two pins, as it is the case following the teaching of the earlier patent document mentioned above, this solution being unsuited to the case of foundry because of their weight and their tolerances of manufacturing.
  • the socket is substantially parallel to the plane of the cover, the mechanism of locking and unlocking is not directly visible, and remains inaccessible to standard tools.
  • the opening gives access to a cavity of the cover in which opens an orifice
  • the opening has an "L" shape including a branch, perpendicular to the orifice, allows the key to pass from any of its locking positions and unlocking when the bushing is inserted in the hole, and prohibits a translation of the arm parallel to the orifice when the arm is substantially perpendicular to the lid while the sleeve is inserted into the hole.
  • the cavity advantageously has a first wall shaped in inclined plane and guiding the socket in the cavity.
  • the latter includes preferably a handle secured to the arm, substantially parallel to the socket, and disposed opposite it.
  • the aforementioned orifice can be formed in a second wall, orthogonal to the first wall, an axis bearing the bolt can then be arranged in the orifice.
  • the aforementioned socket may comprise an internal rib axial joint adapted to cooperate with an axial groove formed on the axis bearing the bolt.
  • the socket of the key includes preferably, at its opening portion, two lugs external opposites likely to cooperate with ribs guide at the bottom of the aforementioned cavity and to cross the aforementioned orifice whose edge has shaped notches corresponding to said lugs.
  • the axis carrying the bolt is for example mounted rotating on an ear parallel to the aforementioned wall comprising the orifice and comprises a flat part for rotationally fastening the axis and the bolt which has a form of square.
  • the bolt is elastically retained by a branch of the square on the aforementioned ear and between this ear and the aforementioned wall with orifice by means of a spring and washers.
  • the other branch of the square forming the bolt is example adapted to cooperate with a notch forming a waste formed in a spar inside the frame.
  • the branch of the square held on the ear has advantageously a hole with flat cooperating with the flat part aforementioned on the axis of drive in rotation of the bolt.
  • a locking device is particularly intended to equip a buffer, cover or the like 1 capable of closing a frame, frame or the like indicated at 2 in FIGS. 5 to 8 and delimiting the opening of a manhole by example.
  • This locking device is operable by a key identified generally at 3 in FIGS. 5 to 12.
  • the upper wall 1a of the buffer or cover 1 has an opening 4 to access the key 3, this opening opening on the one hand to the outside of buffer 1 and secondly in a cavity 5 in the vicinity of bottom of which is mounted the locking mechanism as described in detail below.
  • the key 3 comprises a portion 6 forming a handle and a sleeve 7 connected to the handle 6 by an arm 8.
  • the handle 6 and the socket 7 extend respectively from the two ends of the arm 8 according to two orthogonal directions and of the same direction.
  • the axis X-X 'of the sleeve 7 is substantially parallel to the handle 6 which extends in the same direction than that of said socket.
  • the access opening 4 to the key 3, especially to the socket 7 of this key, is partially closed by a plate or the like 9 which gives the opening 4 a L-shape.
  • a plate or the like 9 which gives the opening 4 a L-shape.
  • the opening 4 presents, following the example of illustrated embodiment, the shape of a rectangle, one of which corners is closed by the plate 9 which has a shape substantially square, so that the remaining part and opening of the opening 4 in the upper wall 1a of the buffer 1 has substantially the shape of an L in which of course be introduced and manipulated key 3 as it is will describe later
  • the cavity 5 associated with the buffer 1, and located below of the plate 9, has a wall 10 in the shape of a plane inclined which guides the socket 7 of the key 3 in said cavity.
  • This cavity 5 also comprises a wall 11, clearly visible in FIGS. 3, 6 and 8 and which is orthogonal to the wall 10 in the form of an inclined plane.
  • the wall 11 has an orifice 12 through which can pass the socket 7 of the key 3, so that said bushing can then come into engagement with a mounted axis 13 journalled on an ear 14 integral with the buffer 1, and bearing a bolt marked generally in 15.
  • ribs opposite guide 16 In the bottom of the cavity 5 are provided ribs opposite guide 16.
  • the ribs 16 constitute a means for abutment and guide in translation of the sleeve 7 of key 3 via two external pins and opposites 17 provided externally at the level of the party outlet 7a of said sleeve 7.
  • the orifice 12 formed in the wall 11 of the cavity 5 has in its edge notches 18 of shape corresponding to the lugs 17 of the socket 7 so as to allow the passage to said socket and allow it to come into engagement with the axis 13 carrying the bolt 15.
  • the sleeve 7 has a internal and axial rib clearly visible at 19 in FIG. This rib can cooperate with an axial groove 20 of corresponding shape formed on the axis 13 which carries and causes the bolt 15, when operating the key 3.
  • This axis 13 is rotatably mounted in an orifice 21 provided in the ear 14 and located in the axis of the orifice 12 arranged in the wall 11 of the cavity 5 and giving access to the socket 7 of Key 3, as will be explained in detail below.
  • the ear 14 is parallel to the wall 11, and between the ear and the wall can turn the bolt 15 which presents the form of a square, according to the embodiment example represent.
  • One of the branches 15a of the square has a orifice 22 with flat 23, as well as the axis 13 of the bolt 15 has a flat surface 24.
  • the two cooperating flats 23, 24 of the bolt 15 and of the axis 13 can cause the bolt to rotate when the rib 19 of the sleeve 7 belonging to the key 3 is in taken with the groove 20 of the axis 13.
  • FIGS. 1, 6 and 8 have been shown in FIGS. 1, 6 and 8 in particular a stack of washers with spring that holds elastically, by means of a pin 26, the branch 15a of the square 15 on the ear 14 between this ear and the wall 11 of the cavity 5 in the buffer 1.
  • the other branch 15b of the square 15 constitutes the part active bolt, in that it is she who will cooperate positively with a notch or the like marked 27 on the Figures 5 and 7 and formed in a spar or the like 28 projecting inside the frame 2.
  • FIG. of buffer 1 on the frame 2 these stops being above of the spar 28 including the notch forming strike 27 to the inside of the frame 2.
  • the socket 7 of the key 3 is introduced through the opening 4 into the cavity 5, and this introduction can only be made for one meaning of the key, namely that visible in Figure 1. More precisely the sleeve 7 slides on the wall 10 in the form of inclined plane of cavity 5, until the lugs opposite 17 of the sleeve 7 abut on the ribs 16 at the bottom of said cavity, as seen in the figure 10 and also in Figures 5 and 6. It should be noted that in this position, the key 3 is blocked by its arm 8 between the edge of the opening 4 and the edge vis-à-vis 9a of the plate 9.
  • the key 3 can not be actuated only by sliding translation of the lugs 17 of the sleeve 7 on the ribs 16 of the cavity 5, and this until the bushing, passing through the orifice 12 of the wall 11, comes into engagement with the axis 13 of the bolt 15 by its rib 19 which enters the groove 20 of the axis 13.
  • Figure 9 shows the bolt 15 in the locked position in the notch 27 of the frame 2.
  • the buffer 1 is "open" and the key 3 remains coupled to the axis 13 and is maintained by its arm 8, trapped in aperture 4 (see Figure 12) which allows, with the key 3, to lift the buffer 1 out of the frame 2.
  • Buffer 1 can of course be returned to the position of closing on the frame 2 with the key 3 which remains trapped in the cavity 5 in the unlocked position of the bolt 5.
