Definitions

  • the invention relates to devices for locking a covering element, for example of the buffer or grid type, on a support frame.
  • a locking device comprising a pivot which extends along a pivot axis crossing the thickness of the covering element and which is fixed to this element so that it can pivot in that -this ;
  • this pivot comprises under the covering element an end region where is fixed a movable locking latch with it between a locking position where it is at least partly opposite a part of the frame or d 'a chin fixed to the latter, and a release position where it is opposite a light in the frame so that the covering element can then itself be pivoted or removed from the frame in order to free the eye, the locking and latch release positions being generally defined by stops.
  • the pivot can be actuated in rotation so as to drive the latch for locking from the locking position to the release position or vice versa, it comprises on the side of its outer end facing the eye, a meshing region suitable for fitting with an engagement region provided at one end of a removable key, when the engagement regions of the pivot and the key are in a predetermined relative position; so when these regions are nested and meshed, a rotation of the key around the pivot axis of the pivot causes the pivot to rotate.
  • the locking device is generally designed such that the key has a head also serving as an operating handle on which one can exert traction to pivot or remove the cover element.
  • the key has in its engagement region one or more pins extending radially outward relative to the pivot axis of the pivot which is also that of the key, and the covering element has , above the pivot engagement region, a bulkhead having a lumen whose outline is similar to that of the cross section of the key when the engagement region thereof is opposite the region of engagement of the pivot in the locked position and in the relative position allowing nesting, but of slightly larger dimensions.
  • the key when the pivot is in the locking position and the engagement regions of the key and of the pivot are opposite in their relative nesting position, the key can be introduced into the lumen of the element of covering and sliding along a section of entry ramp formed by the wall of the lumen and extending approximately in the same direction as the pivot axis of the pivot then fitted with the pivot, and therefore a rotation of the key intended to rotate the pivot slides the lug of the key along a section of retaining ramp extending in a plane approximately perpendicular to the axis, formed by the underside of the lips of the partition the cover member overhanging the engagement region of the pivot; thus, when, as a result of this movement of the “bayonet mount” type, the key has been turned enough so that the pivot is in the release position, any traction exerted on the key is transmitted to the rail of the element lips cover, and it can then be lifted from the frame for example by pivoting if it is pivotally mounted on the frame.
  • the key can then either be removed provided that it is rotated in the opposite direction to the previous one causing the lug to slide along the retaining ramp, followed by a translation causing a slide along the entry ramp, or be left in interlocking relationship with the pivot.
  • the engagement region of the pivot is formed at one end of the latter by a pivot head extending in the longitudinal direction thereof and having a prismatic shape with a polygonal cross section
  • the region of engagement of the key is a chamber of complementary shape (a simple example being a pivot having a male “square” and a key having a female “square"), and where the lug extending radially outward is carried by the lateral surface of the engagement region of the key.
  • the engagement region of the pivot is formed at one end thereof by a pivot head having at the end a slot similar to a screw head slot
  • the engagement region of the key is an end bar extending radially on either side of the pivot axis and adapted to fit into the slot of the screw after having passed through an oblong opening in the upper partition of the element recovery; in this case, the regions of the strip projecting on either side of the axial body of the key themselves play the role of lugs, since after rotation of the key, these two regions of the strip extend under the lips of the partition laterally bordering the oblong lumen and thus allow the lifting of the covering element.
  • a drawback of these locking devices which the invention aims to remedy, resides in the fact that an involuntary rotation of the key during the traction exerted on it to lift the covering element risks bringing the lug or the pins near the entry section of the corresponding ramp, and thus the disengagement of the key and the pivot and the tilting of the covering element either towards the frame or towards the outside thereof, thereby risking injury to the operator.
  • Another drawback which the invention aims to remedy is that the key being held loosely, a small force exerted on it can cause, for example when the covering element is open, its rotation, its accidental fall and even its loss, unnoticed. In this case, the disengagement takes place while the pivot is in the locking position, and if it is then possible to fold the covering element against the frame, it is impossible to lock it.
  • Another disadvantage consists in that, in order to be able to fit the key and the pivot, it is necessary that these are in a correct relative position, obtained only when the pivot is in the fully locked position (preferably defined by a stop) , but it suffices with a slight fortuitous pivoting of the pivot to note, after introduction of the key into the light, that the position of the pivot does not correspond to the position allowing the nesting, and that the latter has become impossible.
  • this chamber which constitutes a trap for gravel and other road surface materials, the presence of which makes it difficult or impossible to introduce the key, is difficult to clean.
  • the invention aims to remedy as much as possible these drawbacks and mainly to avoid that the key can be unintentionally disengaged from the pivot.
  • Preferred embodiments are intended to further remedy the other drawbacks mentioned.
  • the invention relates to a device for locking a covering element on a support frame, comprising a pivot which extends along a pivot axis passing through the thickness of the element cover and comprises on one side of the cover element an end region where a latch is fixed and on the other a mesh end region, and a removable key comprising a mesh end region having at least one meshing pin adapted to cooperate with a respective ramp of the covering element or of the pivot comprising an inlet section extending approximately in the same direction as the pivot axis and a retaining section s 'extending in a plane approximately perpendicular to this axis, the engagement regions of the pivot and of the key being adapted to fit together when the lug is slid towards the fixing end of the latch along the inlet section and the dislocation being made impossible when then by rotation of the key around the pivot axis the lug has been slid along the retaining section unless the key is rotated beforehand ble in reverse, characterized in that the key engagement region further has at least one retractable engagement pin
  • the frame covering element 1 shown in FIG. 1 is a pad fitted with a pivot 2 belonging to a locking device according to a first embodiment of the invention.
  • Pivot 2 which crosses part of the thickness of the pad, extends along a pivot axis perpendicular thereto (in the drawing, perpendicular to the plane of the sheet).
  • the latter comprises in its lower region (when it is in the closed position of the frame) not visible in FIG. 1, a part of the partition pierced with a hole through which the pivot is pinched between two fastening or clamping elements, for example two nuts, carried by the latter; at one end of the pivot 2 which projects below the partition, a locking latch is fixed.
  • the pivot Projecting above this partition, the pivot comprises a base 20 separated from the partition by a seal that prevents the accidental rotation of the pivot (also not visible); the pivot is extended above the base by a prismatic head 21 extending along the pivot axis, having a polygonal cross section. Also above the partition for fixing the pivot, and at a distance therefrom, the buffer 1 comprises, extending in parallel, another partition 10, the role of which will be explained below, pierced with a light 11 more larger dimensions than those of the cross section of the prismatic head, intended to allow the passage of a pivot actuation key.
  • the key 3 shown in Figures 2 and 3 and that of Figures 4 and 5 are intended to actuate in rotation the pivot 2 of Figure 1.

  • a chamber 32 of prismatic shape extending along the pivot axis having a polygonal cross section having the same shape as that of the head 21 of the pivot 2 but of very slightly larger dimensions, so that the chamber 32 can come into interlocking relation with the head 21 and that thanks to their polygonal shape (here pentagonal) these two regions end respectively of the key 3 and of the pivot 2 mesh with each other so that a rotation of the key around the pivot axis causes a rotation of the pivot and thus of the latch around this axis.
  • the head 30 of the keys of FIGS. 2 to 5 being intended to be used as a handle for lifting the plug when the key and the pivot are engaged and engaged in the release or unlocking position of the latch, it is necessary that in this position the key does not have the possibility of dislodging under the action of a simple pull exerted on it.
  • the lateral partition of the engagement chamber of the body of the keys of FIGS. 2 to 5 comprises, in the immediate vicinity of its free end, two lugs 33 extending radially outward and diametrically opposite, and the light 11 of the upper partition 10 of the plug has a shape similar to the outer shape of the cross section of the engagement end region of the key including these two pins but of slightly larger dimensions, in the position occupied by the key when this and the pivot are fitted in the latch locking position.
  • the wall of two notches 12 of the light intended for the passage of the lugs 33 constitutes a section of guide ramp 13 for the lugs when the latter enter.
  • the partition 10 has a thickness sufficient for the regions of its lower face forming ramps are set back upwards, that is to say belong to grooves hollowed circumferentially around the pivot axis in this upper partition, so that the retaining sections 15 extend over an arc of circumference limited by an end

  • the lever 41 is subjected to a return force towards its position of support against the wall of the lights 34 which is closest to the free end of the body, by an elastic return member 44 such as a steel wire to spring, one end of which is wound around the pivot pin 40 for the lever, the central part is wound around another pin 45 parallel to the first and disposed in the upper part of the chamber 32, and the opposite end is in pressure against the upper face of the lever 41 (the farthest from the lower wall of the lights 34).
  • the lug 42 is normally, under the action of the spring 44, in the immediate vicinity of the free end of the engagement region of the key, but is retractable against the force of the member return, for example by pressing upwards, or by lifting its operating finger 43, in the direction of the head 30.
