Definitions

  • the present invention relates to a locking device of an opening on a frame and attached to the inner face of the opening, comprising a locking means, which means comprises a bearing face intended to press the frame in the direction preventing the opening of the opening.
  • the present invention is in the field of locksmithing utensils and their applications, usable for the locking of openings that are encountered in particular in the building, in industrial and agricultural equipment, in furniture and other various uses or the use of an opening is necessary, the opening is removable or articulated around a frame or a frame, for example by means of a hinge, invisible or not.
  • the invention finds a multiple application in the field of the hatches of visit but also in the field of furniture in particular closets or other wall partitions,
  • a partition defines on either side of it an outer zone and an inner zone, which we will also call the outside and inside, to which the opening, fixed on an opening made in this partition, allows a partial or total access.
  • the opening comprises a locking device which conditions this access to the use of this device.
  • the term frame used to describe the invention denotes either a frame itself, or in a global manner the edges of an opening made in a partition with or without reinforcement thereof by an attached frame or formed in the mass of the partition by machining, molding or any other industrial or manual means; it also designates the adjacent walls of a cabinet, on which doors must be able to be locked.
  • threshing locks more or less simple design and commonly used to lock the doors of mailboxes or cupboards for example.
  • the inspection hatches or technical cladding facades allow access to installations located behind an opening in a wall, while ensuring a clean closure when the hatch or the doors are closed. They usually consist of a frame comprising a bottom rail, a top rail and two uprights, an opening, and a locking system, consisting of threshers, operable from outside the portion, and whose bolt engages in a striker fixed on the frame behind the wicket.
  • a locking system consisting of threshers, operable from outside the portion, and whose bolt engages in a striker fixed on the frame behind the wicket.
  • this solution has the disadvantage of presenting an inconvenience to the passage of the opening, by the striker brackets.
  • the pressure on prices has pushed the various manufacturers to find simpler or faster solutions to manufacture.
  • the present invention overcomes these disadvantages by providing a locking device of an opening on a frame and attached to the inner face of the opening, comprising a locking means, which means has a bearing face intended to take support on the frame in the direction preventing the opening of the opening.
  • the device is particular in that said bearing face is offset from the inner face of said opening by a distance of at least 10 mm, preferably at least 15 mm.
  • This arrangement makes it possible to obtain a frame thickness sufficient to withstand the locking force. This avoids the need for a stepped form for the opening, or the need to add a striker on a frame amount.
  • At least part of said locking means has a stair step shape for deporting the bearing face of the inner face of said opening.
  • the locking mechanism can be quite standard, only the bolt having a form specially adapted to the present invention.
  • the locking means comprises a plurality of bearing faces, preferably 2.
  • the presence of at least two bearing faces gives at least two locking positions of the bolt. For a rotary bolt, this allows in particular to lock by turning the bolt in one direction or the other. Moreover, if one locks by turning a quarter of a turn in one direction and then continues the rotation in the same direction, one obtains the unlocking after a rotation of half a turn.
  • the presence of a second bearing face opposite the first one makes it possible to obtain a lock again in the third quarter turn, whereas with only one bearing face, it is necessary to go to the fifth quarter. of turn.
  • At least one of the bearing faces has a convex shape. This arrangement allows easy introduction of the locking means behind an amount or in a groove of the frame for example.
  • the locking means has a protruding shape for gripping by hand to rotate it.
  • said locking means consists of a flat base and two fins folded in the form of a stair step so as to deport said fins of the flat base, said faces of support being arranged on each of said fins, forming a bolt with remote bearing faces.
  • said locking means is adapted to pivot about an axis substantially perpendicular to the inner face of the opening. This pivoting allows a direct action on the bolt, without going through any mechanical device capable of transforming the rotary movement of a key into a translational movement.
  • the pivoting of the locking means is free in both directions of rotation from an unlocked position and limited to about a quarter of a turn in each direction.
  • the present invention also relates to the use of a device according to the invention as a threshing lock.
  • said rotation of the locking means is limited substantially to a quarter of a turn in one direction or in the other starting from an unlocked position, so that for the unlocking it is necessary to rotate in the opposite direction of the direction used for locking.
  • quarter-hole is here used without any notion of precision.
  • FIGS 1 to 3 represent a locking device according to the invention.
  • a blade lock 1 with remote bolt 2 is fixed on the inner face 4 of an opening 3, which is arranged on a frame 5.
  • the threshing lock 1 comprises a plate 6 of elongate shape and consisting of two plates 7 and 8 arranged one on the other, one of which is a folded plate 7, with a shape having folds to create a space 9 between the two plates.
  • the plate 6 is provided with a fixing means 10 of the threshing lock on an opening, which is generally attached to the plate 6 and which can be removable or not of this plate.
  • the fastening means 10 consists of two cylindrical lugs having fin profiles at their periphery which force themselves into holes provided in the opening 3. These lugs may be made of a metallic or plastic material. This simple solution allows a quick and accurate setting of the threshing lock on the opening 3.
  • Other fastening means can be used as an alternative to these lugs 10, such as holes on the plate 6 for the passage of screws or bolts for example.
  • the plates 7 and 8 each have an orifice adapted to cooperate with an axis 11, passing through the two plates through these two orifices.
  • the plates 7 and 8 are fixed together by hard fitting two pins present on one, in two bores present on the other. This operation is done after engaging the axis 11 in the appropriate holes of the plates 7 and 8.
  • Other arrangements are possible by securing the two plates together by conventional means used in locksmithing, these means may be removable or not as the riveting or welding.
  • the figure 3 shows the device in locked position.
  • the bearing face 27 of the bolt 2 is supported on the rear face of the frame, and is offset from the inner face 4 of the opening 3 by a distance of 17 mm in the example shown, which leaves space to accommodate a sufficient frame thickness for the recovery of the locking force by said frame thickness.
  • This distance can be reduced in the case of using stronger materials such as hardwood, but it should be at least about 5 mm, preferably at least 10 mm or even 15 mm.
  • Axis 11 is shown in detail at Figures 4 and 5 and has a flange 12 extended on either side by two cylindrical bodies 13 and 14 concentric.
  • the shaft 11 has two ends, a first end attached to the lower cylindrical body 13 protruding from the plate 7, which end is provided with means for rotating the axis 11.
  • This means as shown in FIG. figure 5 , is a hole 15 of oblong shape adapted to cooperate with a tool acting as a key and whose end having at least two flats is adapted to be introduced into the orifice 15 abutting against the walls 16 of this orifice to entrain in rotation the axis 11.
  • orifice 15 is preferably blind, in particular for fire-resistant opening applications 3, so as to avoid a passage of flame or air in the absence of a key.
  • the shaft 11 has a second end attached to the upper cylindrical body 14 and projecting from the plate 8, which end is adapted to receive a bolt 2.
  • This bolt comprises an opening 17 (see FIG. figure 6 ) able to cooperate with two flats 18 (see figure 4 ) at the end of the upper cylindrical body 14 of the axis 11.
  • This opening 17 and the flats 18 of the second end of the shaft 11 attached to the upper cylindrical body 14 allow a securing of the bolt on this axis, in particular the rotation of the bolt under the effect of the rotation of the axis 11.
  • each set of two plies has a stair step shape, allowing to deport each bearing face 27 relative to the fastening face 28 of the bolt.
  • the bolt 2 comprises firstly a flat base 25, whose fixing face 28 is oriented towards the plate, provided with an opening 17, and secondly two fins 26.
  • the bearing faces 27 of the fins 26 oriented towards base 25 constitute the bearing faces of the threshing lock on the frame 5 (see figure 3 ).
  • These bearing faces are offset from the inner face 4 of the opening 3 by a distance of about 17 mm.
  • These faces can be flat, or curved as shown on the figure 7 . The latter form will facilitate the introduction of the bolt on an amount or in a groove of the frame for example.
  • the symmetrical arrangement of the fins 26 as shown in FIG. figure 6 allows to have an active fin, that is to say in support of the frame, and a free fin.
  • the set of two fins 26 is a protruding shape similar to a manual operating handle, to print the bolt 2 a rotational movement and cause the unlocking of the opening 3 manually from inside the opening.
  • the curved shape of the fins 26 further facilitates their grip by hand. This possibility of manual unlocking is very important in the case where people are introduced into a space and likely to be locked during an unwanted locking of the opening 3 from the outside.
  • the flange 12 projects beyond the two cylindrical bodies 13 and 14, and is inserted between the plates 7 and 8 of the plate 6, which makes it possible to trap the pin 11 in the plate 6 while leaving this axis 11 the possibility of rotate around an axis of rotation 19 (see figure 2 ).
  • the flange 12 has the shape of a rectangular parallelepiped, with edges parallel to the axis of rotation 19 rounded, and eccentric with respect to said axis of rotation.
  • the flange 12 has two parallel flanks 20, and a perpendicular flank 21 eccentric with respect to the axis of rotation 19 of the flange, that is to say farther from said axis of rotation than its opposite flank, and approximately perpendicular to the sidewalls 20.
  • the threshing lock comprises a locking means in rotation of the bolt 2 by means of the locking of the shaft 11.
  • This rotational locking means consists of a pusher 23 and a compression spring 24 (see FIG. figure 1 ).
  • the pusher 23 is free in translation in the part of the space 9 delimited laterally by the two plies of material 22 (see FIG. figure 8 ) which serve as a guide when it is translated under the action of the compression spring 24. Under the effect of the pressure exerted by the spring, the pusher 23 abuts against one of the two parallel sides 20 of the 11.
  • the compression force exerted by the spring 24 and the friction existing between the pusher and the flank concerned allow a locking of the axis 11 avoiding inadvertent unlocking.
  • the plate 8 has two plies of material 22 as shown on the figure 8 laterally delimiting the space 9. This comprises two parts, the first accommodates the flange 12 and the second accommodates the means 23, 24 for locking in rotation of the axis 11 described above.
  • the parallel flanks 20 abut respectively against the end of one of the plies 22 of the plate 7 at the point of contact 29 (see figure 1 ), thus limiting the rotation of the flange 12 to about a quarter of a turn in each direction, starting from the unlocked position, in which the bolt 2 is aligned with the plate 6.
  • the edges parallel to the axis of rotation 19 of the flange 12 are rounded so as to allow the rotation of this flange without abutting on the ends of the folds 22 of the plate 7.
  • the drilled lock 1 to 2 bolt offset described above can be used regardless of a frame 5 with or without a groove adapted to cooperate with the bolt 2.
  • the bearing face of the bolt leaning on one side of the frame facing the inside of the partition for example (see figure 3 ).
  • FIGS. 9 to 12 describe the use of a locking device according to the invention for a inspection hatch, formed by a frame and a gate.
  • the cross members 30, 31 and the uprights 32 of the frame 5 are strictly identical.
  • the groove 33 is made all along each cross member 30, 31 and each post 32, and the assembly is made by a miter system. This makes it possible to manufacture only one reference of parts. At the time of assembly, it is therefore possible to take four identical pieces from one only stock, and assemble them in a frame 5. In the case of rectangular traps, the same principles apply, but it is then necessary to manage two different lengths of pieces. Even after assembly, it is still possible to determine the direction of the frame to assign it to a given opening.
  • the hatch dimensions are generally less than one meter, or even of the order of 300mm.
  • timber of length 2.25m is usually supplied, which is used for larger structures, for example facades of technical ducts. The falls are then very useful to realize the sleepers and amounts for the frame.
  • the gate 3 is cut in a board, without any milling.
  • Two pairs of bores are disposed on the inner face 4 of the gate 3. Each of these pairs of holes is provided to receive two studs 10 attached to the bracket 34 on the one hand, and the thresher 1 on the other hand, which fixes these parts via profiled nylon inserts or other type of plastic. This solution saves positioning time and screwing time for fixing these parts
  • the high or low side of the gate 3 is determined only after completion of these holes.
  • bracket 34 into a lateral amount of the frame, and the bolt of the thresher in the opposite amount, or even to insert the angle iron 34 into the top rail and the bolt of the thresher into the lower rail.
  • the advantage of the fulcrum constituted by the lower crossbar is lost in order to carry out the assembly.
  • the gate is equipped with two threshers 1 with 2 bolts offset, instead of a thresher 1 and an angle bracket 34.
  • the gate is equipped with two threshers 1 with 2 bolts offset, instead of a thresher 1 and an angle bracket 34.
  • the hatch In another variant of the inspection hatch according to the invention, the hatch must be fire resistant. It is then necessary to provide a greater gate thickness 3, as indicated in FIG. figure 12 . As it is sought to maintain the same angles 34 and the same drummers 1 as for a non-fire resistant door, it is necessary to make the groove 33 further back on the frame 5. Depending on the thickness of the frame used, the position of the groove may then be at a position such that there is not much material left on the frame 5 at the rear of said groove 33. The choice then relates to a rabbet at the rear of the frame 5, replacing the groove 33.
  • the fastening means 10 must be adapted to a fire-resistant gate, in particular by the choice of their material. Furthermore, the bearing face of the bolt 2 or the angle 34 on the groove 33 made in the frame 5 must be protected, for example by a metal element, to resist longer in case of fire. A localized protection angle 35 is thus added and fixed to the frame, for example by screwing.
  • the embodiment described above relates to a trap door. But other opening 3 can benefit from the locking device 1 according to the invention.
  • a technical cladding facade articulated around hinges on an amount of its frame can be locked on the opposite amount by a locking device according to the invention, in particular by a remote bolt thresher.
  • a device with two fins, or with curved vanes may be used for a inspection hatch door, fireproof or not, in combination with an angle iron 34 or not.
