Definitions
- the invention relates to a closure device, in especially a lock, to be embedded in a door leaf, of a French window or window.
- the invention relates to a device lock consisting of a latch bolt lock with prismatic head
- the invention aims to solve, in a simple and fast way, the adaptation to an assembly on a door opening to the right or to the left.
- the invention therefore also aims to provide a lock whose characteristics allow a 180 ° turn of the latch bolt around an axis geometric orthogonal to the door edge, in order to transform quickly a right lock to a left lock or vice versa.
- the bolt is a U-bolt whose head prismatic has an oblique face.
- the stop means advantageously consists of a tab linked to the housing and on which it is possible to act with a tool, from the outside of the case, through at least one opening provided in the wall of the lock housing.
- the tab can be secured to the plaster of the housing.
- the plaster of the case is molded in plastic and the leg comes from molding with the plaster.
- Leg can rotate, especially by deformation torsional elastic, around an axis orthogonal to the long face of the housing.
- the tab can be erased, in particular by elastic bending deformation, by a pivoting movement around an axis parallel to the large face of the housing.
- the tab in the rest position extends substantially parallel to the bolt tail.
- the bolt control part is advantageously constituted by an articulated arm at one end on the housing, on the side of the bolt opposite the follower, and the arm has a light in which is engaged the end of the bolt drive, the edges of the light suitable for cooperating with the drive end piece during the rotation of the latter around the geometric axis of the bolt tail being chamfered to facilitate disengagement and re-engagement by rotation.
- the tab may include a boss engaged in a opening of the plaster in the leg rest position, and in abutment against an edge of the latch control piece. This edge may include a notch in which the displacement boss can be engaged of the tab, which allows the exit of the bolt.
- the bolt drive tip is advantageously consisting of a plate whose mean plane is orthogonal to the axis geometric of the rod, this plate having rectilinear edges parallel guided and retained in rotation in the spring housing recall of the bolt, a recess of sufficient diameter being provided at the end housing to allow, when the prismatic head of the bolt is out of the housing, a rotation of the nozzle in this recess.
- the closing device in particular the lock, comprises generally a rod lock bolt whose displacements are controlled, for example, by a bit of a cylinder of security, activated by an authorized key.
- the closing device or the lock includes an indexing means integral with the housing suitable for cooperating with a combined means provided on the bolt. This will prevent the bolt moves outside the maneuvers imposed by the bit.
- the indexing means of the housing can be constituted by a pin, integral of the case, engaged in a window provided in the bolt, this window comprising a median boss defining, on either side, two housings for the pin, corresponding to two indexed positions.
- the closure device or the lock may include a rod brake pressing against a rod boss.
- the brake rod can be constituted by an elastic means, in particular a tongue, integral with the housing and coming from molding with this housing when the latter is made of plastic. This rod brake plays a role of anti-vibration for the rod and allows, in addition, a rod position indexing.
- a closing device in particular a lock
- the distance between the axis of the follower and a part, or headrest, integral with the housing applied against the edge of the leaf of particular importance corresponds to the distance between the hole made in the leaf for the passage of the drive rod controlled by the stand, and the door edge. The tendency is to reduce this distance. The result it is also necessary to reduce the "entry" of the mortise lock by example in a door.
- the displacement of the rod depends, on the one hand, on the effective length of the follower's arm which attacks, at one end, the rod to transform a rotational movement into a movement of translation, and, on the other hand, of the angle of rotation of this arm of follower.
- the angle of rotation of the stand is generally imposed by the specifications and has a value close to 45 °.
- This device is to provide a device for closure, in particular a lock, of the kind defined above which allows, when the lock entry is small, to obtain nevertheless, in end of follower arm, sufficient displacement to ensure a suitable sliding of the rod.
- This system must remain simple and economical construction with a minimum of parts.
- This closing device in particular a lock of the kind defined above is characterized by the fact the follower arm is off-center relative to the follower so that rotate around a point farther from the rod than the center of rotation of the follower, a means being provided for directly driving in rotation by the follower the offset follower arm, without part intermediate.
- the active length of the follower arm is thus increased which allows, despite a small lock entry, to obtain a sufficient displacement at the end of the follower arm, with a minimum of rooms.
- the means for training the arm of follower comprises a finger linked to the follower or to the follower arm, said finger being located radially, respectively, outside the contour a hub of the follower arm or of the follower, and being housed in a recess of this follower arm hub or follower respectively, so as to train the follower arm for the direction of suitable rotation, cooperating with an end stop of the recess, and to move freely in this recess, without train the follower arm, for the reverse movement of the handle or kickstand.
- the closer the finger is to the axis of the follower the greater the travel of the rod, given that the axis of the follower is between the finger and the rod.
- a large face of the lock case comprises a sleeve, of axis orthogonal to the plane of the face, defining at least two decentered scopes respectively guiding in rotation of the follower and the follower arm hub around their different centers of rotation.
- This sleeve may include a bore whose axis passes by the follower center of rotation and an external surface constituted substantially by two half-cylinders of different diameters, but of common geometric axis passing through the offset center of rotation of the follower arm, the two half-cylinders connecting by two shoulders oriented substantially radially.
- the follower arm has, at its hub, a substantially semicircular opening, of the same radius as that of the large cylindrical surface of the sleeve, the ends of the opening of the follower arm hub being connected by a curved cross member defining an inner concave arc of smaller radius, matching the semi-cylindrical surface of smaller radius of the sleeve; a shoulder is formed at each end of the curved cross member to come into abutment against a conjugate shoulder of the sleeve.
- the follower has a circular cylindrical contour housed in the sleeve and a radial branch offset from the plane means of the follower so as to step over the crosspiece of the hub follower so that the finger can enter the recess.
- the case, in particular the plaster is made of plastic; the sleeve formed of two parts of cylindrical surfaces of different diameters comes from molding with the housing.
- center of rotation of the follower and the center of arm rotation are located on a line orthogonal to the rod.
- FIG. 3 we can see a lock 1 to be embedded in a door or window door leaf.
- the lock has a flat case 2 made of a plaster 3 closed, on a large side, with a wall 4 (fig.4).
- the lock is intended, in particular, for the operation of a rod 5 sliding mounted on the edge of the door leaf (not shown), which is located in a vertical plane orthogonal to the plane of the figure 3.
- the rod 5 comprises a lower part 5a, which is lowered for locking, and a high part 5b which is raised for the locking. Locking devices, such as rollers (not shown) are provided on the rod 5.
- a latch bolt 6 is mounted in the housing 2, sliding perpendicular to the direction of the rod 5, i.e. horizontally.
- the latch bolt 6 has a prismatic head 7 with an oblique face 7a and a face 7b parallel to the large face of the lock box.
- the upper and lower horizontal faces of the head 7 have substantially semi-cylindrical guide grooves 7c extending parallel to the large face of the plaster.
- Bolt 6 crosses an opening in a plate 8, or headrest, fixed against the door edge and fixed to the housing 1.
- the opening in the headrest 8 comprises a tail unit 8a engaging in the grooves 7c.
- the rod 5 slides against the inner face of the headrest 8.
- the bolt head 7 is integral with a bolt rod or tail 9 extending horizontally in the housing and provided at its end interior, a tip 10, or piece of bolt drive, extending perpendicular to the plane of Figure 3.
- the tip 10 is consisting of a plate obtained from a circular disc cut along two parallel flats symmetrical with respect to the center and whose ends are connected by arcs of a circle.
- the end piece 10 is guided in translation by the inner wall of a housing 11 (fig. 8) in which a compression spring is mounted 12 pushing the latch bolt 6 outwards.
- the end of the housing 11 located on the side of the head 7 has a recess 11a of sufficient diameter to allow rotation of the nozzle 10 around the geometric axis of the rod 9.
- the end piece 10 is engaged with a control part 13 of the latch bolt which will be discussed later.
- a follower 14 is rotatably mounted, in the housing 2, around of a geometric axis orthogonal to the mean plane of the housing, that is to say perpendicular to the plane of Figures 1, 2 and 3 of the drawings.
- the follower 14 has a square hole 15 to be crossed by a rod drive of combined cross section controlled by a stand 16.
- a torsion spring 14r exerts an elastic return on the follower.
- the stand 16 can execute, from the position of rest, a movement in the first direction, especially a lowering movement, to control the withdrawal of the latch bolt 6 in the housing 1, by a conventional drive mechanism which will not be described in more detail.
- the stand 16 can also execute a movement in the opposite direction, i.e. a movement of lifting as illustrated in Figure 2, to drive in rotation the follower 14 and control the displacement of the rod 5 by through a follower arm 17.
- the follower arm 17 has a hub 18 surrounding the follower 14 and, at its end distant from the center of rotation, teeth 19 suitable for engaging in corresponding openings 20, provided in the lower part 5a of the rod 5. These teeth 19 allow to directly drive the part bass 5a in vertical sliding in response to a movement of rotation of the follower arm 17.
- teeth 19b are provided on the hub 18 for mesh with a toothed sector 19c articulated on an axis integral with the lock box.
- the sector 19c controls the movement of the upper part 5b of the rod, in the opposite direction from the lower part 5a.
- the amplitude of the vertical displacement of the lower rod 5a, in response to a rotational movement of the follower arm 17 of determined angular amplitude, depends on the effective radius of the arm follower 17, i.e. the distance between the center of rotation of this arms and teeth 19.
- the follower 14 rotates around a cutting geometric axis the plane of Figure 1 at point A.
- the distance E between this point A and the outer face of the headrest 8 is the "lock entry" and corresponds to the distance between the hole made in the door for the passage of the rod square drive of the follower 14, and the door edge.
- the invention provides the arrangement set out below.
- the follower arm 17 is off-center relative to the follower 14 so as to turn around from a point B further from the rod 5 than the center of rotation A of the follower, which includes a means 21 for directly driving rotation of the follower arm 17, without intermediate part such as one or several gables.
- the distance from B to the rod 5 is equal to E + Y.
- the means 21 is constituted by a finger 22 integral with a radial branch 23 linked to the follower 14 with which it is integral. Finger 22 is located radially outside the contour of the hub 18 of the follower and is housed in a recess 24 of this hub 18. The finger 22 can drive the follower arm 17 for the proper direction of rotation stand, i.e. the opposite direction of the clock according to the diagram of Figures 1 and 2, cooperating with an end stop of the recess 24.
- This arm 17 has, at its hub 18, a opening 25 substantially semi-circular, centered on point B, the ends of this opening 25 being connected by a curved crosspiece 26 defining an inner concave arc 27, also centered on the point B, but with a smaller radius than most of the opening 25.
- the radial branch 23 of the follower is offset to span the cross 26, so that the finger 22 enters the recess 24.
- the large face of the housing 2 formed by the bottom of the palâtre 3 opposite the foncet 4 has a sleeve 28 of orthogonal axis in the plane of the face, that is to say orthogonal to the plane of FIGS. 1 and 2.
- This sleeve 28 defines, by its outer surface, two bearing surfaces 29, 30 formed by arcs of a circle, of different radius, centered on the point B.
- the bearing 29 has a radius equal to that of the opening 25 and marries the inner circular surface of this opening, while the range 30 has a smaller radius equal to that of the concave arc 27.
- the two ends of the span 30 are connected to the ends of the carried 29 by shoulders 31 in radial orientation, constituting limit switches suitable for cooperating with the respective ends of the cross member 26.
- the angular extent of the span 29 is less than that of the opening 25 so that in the rest position of the stand 16, illustrated in FIG. 1, an angular free space I exists between the upper shoulder 31 and the upper end of the cross-member 26. This angular space corresponds to the authorized upward stroke stand 16, about 45 ° as illustrated in Figure 2.
- the sleeve 28 is advantageously in one piece with the plaster 3 and just molding with him.
- the sleeve 28 has a central opening cylindrical 32 of circular section, the center of which corresponds to the point A.
- the follower 14 has a circular cylindrical outer contour of the same radius as the opening 32 in which it is housed and guided in rotation around point A.
- center of rotation A of the follower 14 and the center of rotation B of the follower arm 17 are located on a straight line orthogonal to the rod 5.
- the finger 21 is located near the upper end of the recess 24, and the free space I is located between the radial shoulder upper 31 and the upper end of the crosspiece 26.
- the end lower of this cross 26 is in abutment against the radial shoulder 31 lower.
- the effective radius of the arm 17, determining the amplitude of the peripheral displacement of teeth 19 for a given angle, is therefore greater than E. This results in a greater linear displacement of the rod 5 in its lower part Sa. At the end of displacement, as visible in FIG. 2, the tooth 19 of the arm 17 which cooperates with the opening 20 of the rod 5 is no longer the same as that of the starting position.
- the solution of the invention allows a reduction of the opening or closing movement of the lock with a compact mechanism and a minimum of parts, training directly the follower arm 17 by the follower 14, without parts intermediate such as one or more pinions.
- This compact mechanism can be integrated into several lock models varying by their entry E.
- the sleeve 28 constitutes a support piece which ensures correct guiding in rotation of the follower 14 and of the follower arm 17.
- This mechanism designed on a base advantageously can be transplanted into any other larger case.
- the invention aims to provide a lock which allows you to quickly and easily turn the latch 180 °.
- the control piece 13 of the bolt is constituted by a substantially vertical articulated arm, towards its upper end, on an axis 33 advantageously made in plastic and molded material with the plaster 3.
- the arm 13 extends downward beyond the bolt 9 and has a light 34 in which engages one end of the endpiece 10.
- the upper and lower horizontal edges of the light or window 34 as visible in FIG. 9, have a chamfer c for facilitate disengagement and re-engagement, by rotation around the geometric axis of the bolt tail 9, of the end piece 10, the small sides are rounded.
- the edges v of the light 34 orthogonal to the axis bolt tail geometry 9 does not have a chamfer pronounced to avoid any disengagement of the drive end 10 in response to a translational movement of the bolt parallel to the axis bolt tail geometry 9.
- the lock comprises a stop means R for the part 13 in the rest position, this stop means being clean to be erased from the outside of the case.
- the stop means R consists of a tab 35 linked to the box 2, and on which it is possible to act with a tool T of the outside of the housing by at least one opening 36 provided in a wall of the housing, in particular provided in the wall 4.
- the lug 35 is itself made of material plastic and comes from molding with the plaster.
- Leg 35 is angled and integral with the plaster; it has at its free end a boss 35a accessible through the opening 36 provided in the hole 4.
- the tab 35 extends substantially parallel to the bolt tail 9 and has a return at right angles 37 secured to the bottom of the plaster 3.
- the tab 35 can pivot, by elastic deformation of torsion, around an axis orthogonal to the large face of the plaster 3, i.e. an axis orthogonal to the plane of Figure 3.
- the boss 35a of the tab 35 forms a stop for a edge of the control part 13, as visible in FIG. 3, and retains this part in the rest position, the latch bolt 6 being so went out normally.
- the edge of the control part 13 comprises, below the zone normally coming into abutment against the boss 35a, a notch 38 in which the boss 35a can be engaged by displacement of the tab using tool T (fig. 5), which allows complete removal of the bolt 6, as illustrated in FIG. 6.
- the control part 13 is retained by the boss 35a resting against the bottom of the notch 38.
- the assembly After turning over the bolt 6, the assembly is returned to place by pushing the bolt 6 inside the housing 1.
- the leg 35 returns, by elasticity, to its normal position illustrated on the figure 3.
- the reintroduction of the head profile 7 is carried out in engaging the grooves 7c in the empennage of the headrest 8.
- FIGS 10 to 13 show an alternative embodiment in which identical elements or playing analogous roles are designated by the same reference numbers possibly preceded from the number 1 of hundreds.
- the stop means R is constituted by a tab 135 coming molding with the plaster 3 plastic. We find the boss 135a cooperating with an edge of the part 113 to retain it in rest position. However, the edge of this piece 113 does not include more indentation.
- the erasing of the tab 135 is carried out by a pivoting movement about a vertical axis, parallel to the large face of the plaster panel 3, so that the boss 135a passes in rear of room 113, according to the representation of the drawings, when exerts on the boss 135a a thrust using a tool T (fig. 13).
- the T tool to use is standard and common, for example screwdriver, point, knife, scissors.
- plastic for example acetal, polyacetal, loaded or not, with plaster 3 and legs 35, 135 and others elements coming directly from molding, is particularly advantageous.
- the lock has in the lower part, in the embodiment envisaged, a deadbolt 39 for the locking of the rod 5.
- This bolt 39 can be moved in circular translation by a bit 39a of a safety cylinder 39b controlled by a key.
- the bolt 39 has a window 40 (fig. 7) having a median boss 41 defining on both sides a housing indexing.
- a pin 42 integral with the large face of the plaster 3 is planned to enter this window, this pawn having a certain elasticity.
- pin 42 is also made of plastic and comes molding with the plaster.
- Pawn 42 is placed in one or other of the housings located on either side of the boss 41 and crosses this boss by elastic deformation during the movement of the bolt.
- Pawn 42 allows for position indexing of the bolt, exerting a slight elastic pressure force against the edge of the combined window and prevents the bolt from moving outside the maneuvers imposed by the safety cylinder bit.
- a rod brake 43 is further provided in the form an elastic tongue 44 fixed to the plaster 3.
- the tongue 44 is also made of plastic material and comes from molding with the plaster.
