Description

LOCK DEVICE

  The invention relates to a lock device of the type which includes a tubular type lock comprising the

  elements of a conviction system, including a bolt and a counter

  bolt, this lock device being intended to be mounted on a door which, at the edge, clamps a seal against the frame when the door is closed, while the bolt of the lock enters a

keeper provided on the door frame.

  A tubular type lock allows security to be achieved by any locking system: mechanical, electrical, electronic (card lock), magnetic or other, which is advantageous The tubular lock also makes it possible to adapt a barrel or a button, optional, for ordering The tubular lock is also quieter, which is appreciable in apartment buildings, hotels etc where people can open or close doors

  while other people are sleeping.

  However, closing the door with such a tubular type lock used in combination with a door seal is not always obtained satisfactorily. Indeed, if the door seal, to be crushed, requires significant effort , the entry of the bolt into the strike plate during closing is relatively difficult to obtain Otherwise, if the door seal crashes easily, the door is closed more easily, but the door is not not properly held in its closed position It can

  result in poor sound insulation and / or heat loss.

  The object of the invention is, above all, to provide a lock device of the type defined above which, while remaining silent, allows satisfactory closing of the door with an appropriate seal, in order to improve sound insulation and reduce losses.

heat.

  According to the invention, a lock device of the kind defined above, is characterized in that the tubular lock is coupled with compression means, distinct from the elements of the tubular lock, making it possible to compress the door seal after closing this last, so that the bolt is then moved away from the edge of the strike, and that at least one of the elements of the counter-bolt / strike pair is arranged so that the counter-bolt remains in contact, outside , against the strike despite the movement

  relative to the bolt and striker during compression of the joint.

  The solution of the invention therefore makes it possible to effectively compress a door seal which is sufficiently resistant, without however requesting the bolt of the tubular lock which no longer supports the forces of the compressed seal. The entry of the bolt of the tubular lock into the strike s '' performs easily since there is no lo significantly compress the door seal, this compression being

  performed in a later phase.

  According to a first embodiment, the latch has dimensions sufficient to remain in abutment, outside against the strike The edge of the opening of the strike, close to the latch,

can then be straight.

  According to another embodiment, the edge of the opening of the strike close to the latch has a projecting part, towards the inside of the opening, at the level of the latch which remains in abutment against this projection during movement of the bolt due to compression of the seal, the bolt having a notch in

  which can engage said projecting part.

  Advantageously, the compression means are arranged to ensure, simultaneously with the compression of the seal, a

  additional door lock.

  Preferably, the tubular type lock is mounted on a headrest and the compression means comprise, mounted on the same headrest, a larder lock box and a rod slidingly mounted against the headrest, the movements of this rod being ensured at using control means provided in the trunk, the rod being equipped with projections, in particular rollers, intended to cooperate with complementary means, in particular notches provided with ramps, provided on the frame, so that a vertical sliding protrusions, in particular rollers, causes, by cooperation with the complementary means, the compression

of the joint.

  The control means provided on the trunk preferably comprise a stand. Advantageously, the compression of the seal is ensured by a movement of the stand (raised or lowered). The aforementioned control means further comprise, inside the trunk, a nut rotatably mounted in the trunk under the action of the crutch, an arm linked to the follower and comprising notches adapted to cooperate with a biased indexing finger elastically against the arm in the radial direction, and a rod driver connected to the

1 o arm by a link.

  The sliding rod has two parts located on either side of the tubular lock, connected by a bypass bracket

said tubular lock.

  The mortise lock housing fitted with the handle can be

  1.5 placed above the tubular lock.

  The handle is only provided on the inside of the door.

  This stand preferably comprises a shaft with a square section capable of cooperating with a passage of corresponding section provided in the follower The end of this passage of square section, situated on the outside, is closed by a plug, for example made of plastic, which can be removed to activate the larder box mechanism from outside the door in case

of necessity.

  The invention consists, apart from the arrangements set out above

  above, in a number of other arrangements which will be more explicitly discussed below in connection with exemplary embodiments described with reference to the accompanying drawings, but which are not

in no way limiting.

Figures 13 and 14.

  Referring to the drawings, in particular to Figures 1 and 2, one can see a lock device 1 comprising a lock 2 of the conventional tubular type which will not be described in detail. The tubular lock 2 comprises two control buttons 3, 4, cylindrical example, intended to be respectively inside and outside the door The interior button 3, when the door is closed, is located in the room, room or apartment for example, to which the door gives access Both buttons 3, 4 are coaxial and allow, by their rotation, to act on the elements of a locking system provided in lock 2, a system which can be mechanical with a barrel as illustrated in FIGS. 1 and 2, or electric, electronic (card lock), magnetic or other. The locking system of the lock 2 comprises a bolt and a latch 6 extending transversely relative to the axis of the buttons 2 and 3 The connecting means making it possible to move the bolt 5 in response to a rotation of the button 3 , 4 are housed in a tubular casing 7 extending orthogonally to the axis of the buttons 3, 4 This casing 7 is intended to be embedded in the thickness of the door while the latch 5 and the latch 6 protrude on the

vertical edge of the door.

  The lock 2 is fixed on a headrest 8 constituted by an elongated rectangular metal blade, intended to be fixed on the vertical edge of the door The axis of the casing 7 is perpendicular to the plane of the headrest 8 The bolt 5, as illustrated in Figure 7, is intended to enter a keeper 9 provided on the frame 10 during the

door closed 11.

  The door 11 is provided, at the edge, with a seal 12, of flexible material, which has been shown in FIG. 7 with a triangular horizontal section but which may have the shape of a bead or any other shape. The edge of the door extends beyond the bolt 5 so as to be facing a dormant part of the frame for the compression of the seal 12 between the frame and the door It is clear that this seal could be provided at a other place and, if necessary, fixed on the dormant part of the frame 10 It suffices that the seal 12, when the door is closed, is compressed between this

last and the door frame.

  The tubular lock 2 is coupled with compression means C, distinct from the elements of the tubular lock 2, making it possible to compress the door seal 12 after closing of

the latter.

  When the seal 12 is compressed, as illustrated in FIG. 9, the bolt 5 is spaced a distance d from the neighboring edge 9 a of the keeper 9, while before compression of the seal 12, the door being closed as illustrated in FIG. 7, the bolt 5 is in contact against

  the edge 9 a of the striker 9 The edge 9 a is straight, vertical.

  The counter bolt 6 which is located on the inner side of the lock 2 has a dimension e in the direction of the arrow A (corresponding 1 o to the movement, in the horizontal plane, of the bolt 5 and of the counter bolt 6 during the closing), sufficient for the counter-bolt 6, as illustrated in FIG. 9, to rest, outside, against the keeper 9 despite the relative movement of the bolt 5 and the keeper 9 leading to the creation of the distance d between bolt and strike plate This prevents the is-bolt 6 from entering the opening of the strike plate 9 and no longer exerts its

  bolt blocking function 5 It is recalled that the counter

  bolt 6, when it is pushed back by the keeper, as illustrated in FIGS. 7 and 9, when the door is closed, blocks the bolt 5 and opposes an erasure of this bolt 5 from the outside by the action of a

tool or other instrument.

  The compression means C comprise a box 13, substantially in the shape of a rectangular parallelepiped, with a mortise lock, fixed on the same faceplate 8 as the tubular lock 2, this box 13 also intended to be embedded in the thickness of the door. 11 The compression means C further comprise a rod 14 constituted by a metal plate, mounted to slide against the headrest 8, in the vertical direction when the assembly is in place on the door. The movements of the rod 14 are ensured by using control means E provided in the trunk 13 The rod 14 is equipped with projections, advantageously constituted by rollers 15 rotatably mounted around axes orthogonal to the planes of the rod 14 and the headrest 8 The rollers 15 are located on the side the headrest 8 opposite the rod 14; the axes of these rollers pass through windows 8a, oblong in the vertical direction, provided in the headrest 8 to allow vertical movement of the rollers These rollers 15 are intended to cooperate, as illustrated in FIGS. 6, 8 and 10, with Respective notches 16 provided in the frame 10 Each notch 16 has a ramp 17 arranged in such a way that after engagement of the roller 15 in the inlet 18 of the notch 16, the cooperation of the roller 15 and the ramp 17 during the vertical sliding movement of the rod 14, causes a displacement of the door 11 in the direction which ensures the compression of the seal 12 During this movement, the roller 15 descends to the bottom of the notch 16 and

  cooperates with the vertical walls 19 of the bottom of this notch 16.

  o O The cooperation of these walls 19 and of the roller 15 ensures additional locking of the door 11, in

  several points corresponding to the various rollers.

  In the embodiment considered, the compression of the seal 12 and the additional locking of the door are obtained by a downward movement of each roller 15 in its notch

  respective 16, the entry 18 of the notch being in the upper part.

  The sliding rod 14 is made in several parts, including two parts 14 a, 14 b located on either side of the tubular lock connected by a stirrup 20 (see FIG. 2) bypassing said

  tubular lock on the casing 7.

  The control means E for the sliding of the rod 14 comprise, inside the trunk 13, a nut 21 constituted by a circular part provided with two diametrically opposite radial extensions and comprising a central passage 22 to 2 S square cross section suitable for receive a square section shaft controlled by a stand 23 located on the inside of the lock The follower 21 is rotatably mounted around its axis in the housing 13 An arm 24 having a hub linked in rotation to the follower 21 is provided This arm 24 is linked by a joint 25 radially spaced from the axis of the follower, to the end of a link 26 whose other end is articulated on a driving element 27

  parts of rods 14 a, 14 e to which it is linked.

  The hub of the arm 24 has notches 28, 29 adapted to cooperate with an indexing finger 30 resiliently biased in the

  radial direction against the periphery of the arm hub 24.

  When the stand 23 occupies the horizontal position of FIG. 2 or 3, the finger 30 is engaged in the notch 29, as illustrated in FIG. 12, and the driver 27 is in the high position to which also corresponds a high position of the rollers 15, located at

  s level of entry 18 of their respective notch.

  When the stand 23 is raised as illustrated in the figure, the follower 21, as shown in Figure 12, has rotated clockwise to the position shown in Figure 11 where the finger 30 is engaged in the notch 1 o 28 The coach 27 is lowered and the rollers 15 have moved, towards

  the bottom, by a distance represented by the stroke j in FIG. 5.

  That said, the establishment and operation of the device

  according to the invention are as follows.

  The buttons 3 and 4 are removed from the cylindrical casing 7 as are the elements of the tubular lock 2 orthogonal to this casing 7; the crutch 23 and its square shaft are removed from the larder lock box 13 The tube 7 and the box 13 are embedded in housings provided in the thickness of the door while the headrest 8 is fixed on the vertical edge of the door , a groove being provided in this edge to allow the sliding of the rod 14

  between the bottom of the groove and the headrest 8.

  The axis of the crutch 23 is then introduced, from the interior side of the door, through the passage 22 with the desired orientation of the crutch 23 The end of the passage 22 located on the exterior side of the door is closed by a plastic plug, not visible in the drawings The elements of the tubular lock 2, orthogonal to the axis of the tube 7, are put in place through a passage provided in the door and the buttons 3 and 4 are mounted The lock is

ready to go.

  When the door is open, the elements of the lock occupy the position shown in FIG. 3, that is to say that the crutch 23 is horizontal, the rollers 15 being in the high position The bolt 5 is out; the counter-bolt 6, as clearly visible on the magnifying glass

  relating to FIG. 3, has come out to the maximum.

  The door is closed by simple slamming.

  The inclined face 5a of the bolt 5 by coming into contact with the outer edge of the strike 9 causes the bolt 5 to retreat, against elastic means, and, when the degree of closing of the door is sufficient, the bolt 5 is located opposite the opening of the strike 9 and enters this opening as illustrated in FIG. 7 This position corresponds to that of FIG. 4 The bolt 5 is in the extended position while the counter bolt 6 is in the position retracted from the fact that it is in abutment against the edge of the keeper 9, as clearly visible on the

lo figure 7.

  Because the counter bolt 6 is kept in the retracted position, the bolt 5 is blocked in its extended position and cannot be

operated from the outside.

  The rollers 15 remain in the high position, as can be seen in FIGS. 4 and 6, but are partially engaged in the entry

  high 18 of the notch 16 associated therewith.

  The seal 12 is practically not compressed.

  To ensure good thermal and / or acoustic insulation and / or sealing, it is sufficient for the person who is on the interior side of the door to manually carry out an operation of raising the stand 23 to bring it into the illustrated position in FIG. 5 As a variant, this command could be provided by a

  lowering movement of the stand.

  This action causes, silently, the descent of each roller 15 against the ramp 17, in the corresponding notch 16, which compresses the seal 12 as illustrated in Figure 9, while the bolt 5 moves away from the inner edge of the keeper 9. Thanks to its sufficient width e, the latch 6 remains in contact

against the strike 9.

  The door is completed with the entry of

rollers 15 in the notches 16.

  It is clear that instead of rollers 15, one could provide bolts or hooks, also controlled by parts of rods 14 a, 14 b, 14 e adapted to cooperate with corresponding parts

provided on the frame.

  Referring to Figures 13 to 16, we can see another embodiment and another arrangement of the pair of bolt 106 / strike 109, to allow the bolt 106 to remain in support

  against the keeper 109 when the seal 112 is crushed.

  The edge 109 has, from the opening of the strike, close to the counter

  latch 106 has a projecting part 31, towards the inside of the strike opening This part 31 is constituted, as visible

  1 o in FIG. 16, by a rectangular tongue 32, provided at mid

  height of the edge 109 a_ situated in the vertical plane of the opening, orthogonal to the plane of the closed door The bolt 105 has a notch 33 in which said tongue 32 can engage, which allows the bolt 105 to enter the opening of the striker as

  is shown in Figures 13 and 14, without being stopped by the tongue.

  Against the bolt 106, however, remains in abutment against the tongue 32 when the door seal is compressed, as illustrated

in Figure 14.

  With such an arrangement, the dimension (thickness) of the counter

  latch 106 in a direction perpendicular to the plane of the door may be weak, the retention of the latch being ensured by the

tongue 32.

  The lock device according to the invention makes it possible to obtain good insulation of a door, in a simple manner,

efficient and silent.
