  LOCK WITH HOUSING AND SLIDING TARGET

MOBILE IN THE LAST

  The present invention relates to a multiple lock

  slide slide mounted in a box type housing, guided by an actuation mechanism in

  a cutout of a side wall of the housing, and which can

  smooth from an unlocking position to a locking position, lock in which the sliding bolt is retained in the housing by means of a cover plate for said lock; wherein the actuation mechanism by means of a stopper pin is accessible via a cutout made in the cover plate of the lock; '' in which the sliding bolt has, on the lock side, at least one arm which surrounds a movable control part perpendicular to said bolt, on a side oriented parallel to the direction of movement of this bolt, and which is connected to the control part and to the stop pin, through a drive pin and

  a guide rail, so that when

  placing the stop pin to a working position from a starting position projecting beyond the housing, the sliding bolt moves, in said housing, from the unlocking position to the locking position; in which the sliding bolt returns to the unlocking position when the control part is moved to the starting position, from the working position; and in which a snap-in dowel of the

  control part is guided in a support provided with a

  smooth-selection, so that the position of ver-

  rusting of the sliding bolt can be triggered by

  an additional stroke of the control part.

  A lock of this type is known from patent DE-C 2-35 04 806 In this known lock, the stop pin governs a control piece which is separate from the sliding bolt, and is provided with guide slides oriented

  towards the arms of said targette

  ment, arranged integrally on the arms of the targette,

  enter these slides The control part receives the stop pin and is moved, at the same time as the latter,

  perpendicular to the direction of movement of the tar-

  gette The control part then crosses the practical cut

  quée in the cover plate of the lock and determi-

  therefore, by its cross section, the bore in the door, the rosette and the actuation button As a result, the actuation button and the rosette cannot negatively exceed a determined dimension Such

  closure system has a coarse appearance on a small

  this door is of the classic type, for example, in the construction

tion of caravans.

  The subject of the invention is a lock of the men-

  tioned in the introduction, carried out in such a way that, by means of a simpler structural arrangement of the actuation mechanism, it is possible to use an actuation button and a

  rosette which have a significantly smaller diameter.

  In accordance with the invention, this object is achieved by the fact that the arm of the sliding bolt carries the guide slide on the side facing the stop pin;

  and by the fact that a protruding drive pin,

  swung securely on the stop pin as a control piece, enters directly into the guide-slide of

  sliding slide and is guided there with the ability to move

cement.

  Thanks to the elimination of the control panel

  tincture, the sliding bolt can be directly attached

  bent to the stop pin inside the housing Now it

  it suffices that the cover plate of the lock is trapped

  poured by the locking pin, the diameter of which can

  easy, be reduced to 10 mm Thus, the lock is also suitable

  lie in doors of reduced dimensions, and its appearance is not

no longer as rude as before.

  According to an embodiment characteristic, the report

  elastic pel in the starting position, after the necessary additional stroke is obtained thanks to the fact that the end of the locking pin which protrudes into the housing is pierced with a

  blind hole into which a household pin can be inserted

  secured integrally on the bottom of the housing, and onto which a pressure spring is threaded, said pressure spring bearing against the bottom of said housing and in said blind hole. According to an embodiment characteristic, the connection

  between the actuation button and the stop pin is disso-

  ciée by realizing the free end of said stopper in the form of a threaded part, on which can be screwed an actuation button with an external diameter which is

  adapted to the external diameter of said stop pin.

  An improvement in the guiding of the stop pin, during movement, is obtained by the fact that a block of

  guide, provided with guide ribs, is formed integral-

  at the end of the stop pin located on the housing side; and by the fact that the guide ribs of the guide block are movable in grooves for guiding the walls of the housing,

  with the ability to move parallel to the locking pin.

  According to one embodiment, the support is

  viewed in such a way that the locking pin carries, on the turned side

  opposite the sliding bolt, the ankle clicks into place

  table supported by the selection slide of said support

  Harbor; that this support is guided, in the case, with fac-

  displacement tee transversely to the direction of movement of the sliding bolt, and bear against said housing by means of support springs, on the side turned away from the sliding bolt, with limited movement capacity in the direction of the displacement of this

  targette; and that the support selection slide presents

  te, for the snap-in plug, a snap-in housing which; when the locking pin occupies the working position,

  firmly retains said snap-in dowel in a position

  latched tion to which this ankle can be brought,

  and from which it can be released again by an ad-

  respective button button.

  According to an embodiment characteristic, so that the small actuation button can, in this way also, be well maneuvered, in particular during the completion of the additional stroke, it is provided that said actuation button comes to flower, in the overtaking position, with a rosette inserted in a hole made in a door; and that in the working position of the

  stop pin, this actuation button protrudes from the roset-

  te, by a distance corresponding to the additional stroke.

  A symmetrical action of the displacement force, on the sliding bolt, is achieved by the fact that this sliding bolt has two arms which trap two mutually opposite sides parallel to each other

  of the locking pin and are provided, on the internal faces turn-

  born towards each other, from guide rails coinciding

  your; and by the fact that the locking pin carries drive pins projecting from one another in the

diametrical direction.

  In order that the latched position of the support also implies an unequivocal permanent locking of the sliding bolt in its position, it is provided that the guide slides, formed in the arms of the sliding bolt, have an inclined region of displacement which merges into a overtravel region, perpendicular to the direction of movement of said sliding bolt

  and that, in the working position, the drive pins

  of the locking pin are arranged in the extreme zone

  of the regions where the slides are exceeded

  guiding res In this way, the drive pins of the stop pin clearly block the sliding bolt in

the locking position.

  The invention will now be described in more detail.

  tion, integrated in a bore 11 made in a door or a leaf 10 A box 19 of the box type houses a sliding bolt 21 which, in the unlocked position, is retracted to come flush with a cutout 20 formed in a side wall of said housing 19 The bolt 21 widens in the housing 19 and forms two arms 22 and 24 configured in plates, which are oriented in the direction of movement

  of said bolt 21 and are perpendicular to the latter

  re Housing members or the like guide the bolt 21 so that it can be moved in the

  housing -19, up to the locking position according to the fig-

  re 4, in which said bolt 21 protrudes beyond the side wall provided with the cutout 20 On the faces turned towards one another, the arms 22 and 24 of the bolt 21 carry guide rails 23 and 25 which start from the upper face of said arms 22 and 24, oriented towards a plate 32 covering the lock and closing said housing 19

  and which then form an inclined region of displacement,

  clinching towards the rear wall of the housing and the bottom of this housing, and merging into a vertical region of excess travel The plate 32 for covering the lock is snapped into the housing 19 and engages, by a flange, in drilling 11 made in the door or

the wing 10.

  A stop pin 13, movable in the cutting of the

  lock cover plate 32, door, in box -

  tier 19, two diametrically oriented drive pins 16

  These drive pins 16 are introduced into the guide rails 23 and 25 of the arms 22 and 24 of the

  sliding bolt 21, so that, when moving

  ment of said lug 13 in the direction of said bolt 21, the

  said pins 16 move this bolt 21, through the

  placing of the regions of displacement of said slides 23 and 25, up to the locking position illustrated in FIGS. 4 and 5 At the stage of displacement of the pin 13, the non-rotary guidance of this pin 13 is improved by means of a guide block 28 formed integrally on said stud 13 and guided, by two guide ribs 29, in guide grooves 27 of walls 26 of the housing As the view reveals

  plan of FIG. 2, these walls 26 also apply

  quer, in part, around the perimeter of the post 13.

  The locking pin 13 is movable, outside the plate 32 'covering the lock, in a rosette 12

  introduced into the bore 11 of the door or leaf 10.

  The free end of the stud 13 is produced in the form of a threaded part 14 of reduced diameter, onto which an actuating button 15 is screwed. The external diameter of this button is adapted to the external diameter of the stud 13, so that 'It can be pressed into the rosette 12 A pressure spring 31, threaded on a pin 30 at the bottom of the housing 19, must then be compressed as shown in Figure 3 In this case, the pin 30 and the spring 31 are inserted in a blind hole in the tenon 13 The spring 31 then takes support in the

  blind hole in the tenon 13 The sliding bolt 21 is

  placed until the drive pins 16 of the te-

  no 13 reach into the overtaking vertical regions

  of the guide rails 23 and 25.

  As shown in Figure 5, the arms 22 and 24 of

  the sliding bolt 21 are extended to the underside

  dull side wall pierced with the cutout 20, and con-

  help define the locking position which is assi-

  pinned once and for all to said bolt 21.

  A snap-in dowel 17 formed integrally on the guide block 28 of the stop pin 13, opposite the sliding bolt 21, is guided in a slide for selecting a support 18 known by itself This support 18 takes support on the housing 19 by means of elastic tabs, so that it is resiliently damped and can achieve a limited displacement in the direction of movement of the bolt 21 The selection slide of the support 18 is arranged so that a additional travel of the lug 13, i.e.

  the displacement of the drive pins 16 in the re-

  vertical gions for exceeding the travel of the guide rails 23 and 25, brings the snap-in pin 17 to a snap-in position in the support selection slide

  18 During this additional run, the action button

  ment 15 comes substantially flush with rosette 12 and, in

  the latched position corresponding to the position of ver-

  rusting of the sliding bolt 21, said button 15 de-

  pass, from said rosette 12, from a distance representing

  so much said additional stroke The pegs

  16 are located in the upper end zones of the over-travel regions of the guide rails 23 and 25 and thereby ensure the locking position.

  of the bolt 21, as shown in Figures 4 and 5.

  The arms 22 and 24 of the sliding bolt 21 extend from the bottom of the housing to the internal face of the

  cover plate 32 for the lock, and are therefore

  quent also guided, in said housing 19, on these two sides.

  This design of the lock eliminates the need for a clean operating part, since the locking pin 13 forms the

  actuation mechanism in combination with the targette

  smoothing 21 Said tenon 13 combined with the actuating button 15 can perfectly, in this case, be reduced to a diameter

external of the order of 10 mm.

  It goes without saying that many modifications can

  be made to the lock described and shown, without

from the scope of the invention.
