Description

LOCKING DEVICE HAVING AT LEAST ONE LOCKING POINT

FOR SLIDING CHASSIS

  The invention relates to a locking device with at least one locking point for a sliding frame. The locking devices according to the invention are particularly suitable for the tight locking of windows, doors, sliding patio doors or the like constructed by assembling profiles, in particular of

aluminum profiles.

  Document FR 2,689,926 describes a device for locking at least one locking point, in particular for windows, doors, sliding glass doors or the like comprising at least one profile. This device comprises a lock external to the profile provided with a locking member and an actuation means external to the profile, a second actuation means

  inside the profile and at least one locking member.

  Said first actuation means passes through a first wall of the profile to cooperate with a corresponding shape of said second actuation means. Said second actuating means is kinematically connected to the locking member through a second wall of the profile to produce a movement in translation or in rotation of the locking member (s). The lock and the profile are crossed by a single locking member such as a barrel controlled by a key capable of being engaged at least on one side of the window or sliding door or French window; and the kinematic connection between a said second actuation means inside the profile and a said locking member is established by means of actuation blades capable of sliding externally on the edge wall of the profile, This device of known type generally gives satisfaction , but has the disadvantage of a leak during the closing of the window, sliding door or French window. This leak is due to the fact that the sealing brush seals do not cover the side face of the fixed upright of the sliding window, door or patio door due to the offset produced by the thicknesses of the headrest and the action blade

of this known device.

  The object of the invention is to remedy this drawback, by eliminating the offset di to the thicknesses of the headrest and of the actuating blade of the known device and by improving this known device so that the sealing brush seals can provide a comparable or better seal than that provided by

  other devices of the prior art.

  The subject of the invention is a locking device with at least one locking point, in particular for windows, doors, sliding patio doors or the like comprising at least one profile, of the type comprising a lock external to the profile; said lock comprising an actuating member penetrating inside the section for controlling the translation of a movable assembly; said movable assembly comprising a member cooperating with said actuating member secured to an actuating or guiding blade in translation; said actuating or guiding blade in translation supporting at least one locking member, characterized in that said movable element is contained inside

of said profile.

  According to other characteristics of the invention: Said mobile assembly is held against the edge

  inside of the profile by fixing means.

  Said fixing means comprise fixing plates arranged between depth adjustment blocks of the locking members and the edge

inside of the profile.

  The fixing means carry a member capable of preventing the closing of the sliding window, door or French window, so as to avoid any shock of the

  locking on the corresponding strikes.

  Said cooperating member has a fork shape. The locking member (s) has a hook configuration, The locking members are separable from the moving element, so as to mount the moving element inside the profile and to mount the locking elements through lights crossing the edge of the profile. The locking members are fixed by means of at least one fixing means forming an angle with the direction of depth adjustment of the

locking devices.

  Said fixing means simultaneously maintains in place and blocks the depth adjustment of

the locking member.

  The moving part is held in position by a

means of indexing.

  The invention will be better understood thanks to the

  description which will follow given by way of example not

  limiting with reference to the accompanying drawings in which: Figure i schematically shows a perspective view with partial cutaway of a device according to

  the invention in the open position.

  Figure 2 shows schematically a cross section along the 1 line II-II of Figure i of

device according to the invention.

  Figure 3 schematically shows a cross-sectional view along line III-III of Figure 1

of a device according to the invention.

  FIG. 4 schematically represents a view in longitudinal section along IV-IV of FIG. 1 of a

device according to the invention.

  FIG. 5 schematically represents an enlarged longitudinal section view of a device according to the invention. Referring to Figures 1 to 3, a device according to the invention comprises a lock 1 extérieu.re to a profile 2 and provided with an actuating means 3 passing through a side wall of the profile 2 by an opening provided for the translation of the operating member 3 in the direction of the arrow 4. In its longitudinal translational movement, the operating member 3 controlled by a key engaged in the lock causes the displacement of a fork 5 secured to a blade d actuation 6. The actuation blade 6 carries at its opposite ends two housings 7a, 7b carrying removable hooks 8a, 8b able to engage in strikes or openings G of the fixed amount 9 of the door, window or door- Sliding window. Two fixing plates 10a, lo0b are locked in sliding between the actuating blade 6 and the blocks 7a, 7b. A plate, for example the lower plate lo0b, carries a retractable stud 11 preventing false operations in order to avoid deterioration of the bolts during closing by sliding in the direction of arrow 12. Thanks to the invention, the blade actuator 6 is entirely contained inside the profile 2; the actuating blade 6 no longer constitutes an obstacle to the closing of the sliding door, window or French window and allows the application of the brushes 13a, 13b carried by the profile 2 on the sealing faces 9a, 9b of the fixed amount

  9 of the sliding door, window or French window.

  The invention, by allowing the application of the brush seals 13a, 13b on the lateral sealing faces 9a, 9b, thus provides an equivalent closure seal or

  better than that of other devices of the prior art.

  In addition, because the actuating blade 6 is internal to the profile 2, the aesthetic appearance of the sliding door, window or French window is greatly improved due to the fact that the edge of the profile 2 does not have any discontinuity in appearance with the lateral faces of profile 2. This arrangement is particularly advantageous for aluminum profiles

lacquered or anodized.

  The plate 1ob carries a movable element 14 subjected to the action of a spring 15 and into which the stud 11 is screwed from the outside. The stud 11 is thus fixed in position relative to the edge of the profile 2 and is held fixed in position relative to the profile 2 while being trapped in the circular opening 16 in which it

is engaged.

  Due to the fact that the control fork 5 and the actuating blade 6 as well as the plates 10a, 10b comprising at least one movable element 14 subjected to the action of a spring 15 are all internal to the profile 2, the positioning this assembly is carried out simply by 91gissant by end of the profile, after which the stud 11 is screwed into the element 14 through the orifice 16 formed in the edge of the profile, With reference to Figures 4 and 5, the elements of identical references to the references of FIGS. 1 to 3 designate elements which are identical or functionally

  equivalent to those in Figures i to 3.

  The fixing plates 10a, o10b are trapped in sliding between the blocks 7a, 7b carrying the hooks 8a, 8b and the actuating blade 6. Thus, during attempted break-in, the force resulting from the break-in is applied to the hooks 8a, 8b which are retained in the support blocks 7a, 7b, which are braced on the actuating blade 6 and on the inside of the edge of the profile 2. This arrangement makes it possible to use the thickness of the profile to resist the forces exerted during an attempted break-in. Therefore, the blade 6 can be a thin blade and the fixing plates 10a, 10b can be reduced to segments of minimum length, since they do not participate in resistance to burglary. On the contrary, in the prior art, the fixing headrest was fixed to the outside on the edge of the profile and had to have a length and a thickness sufficient to resist burglary forces alone. In addition, to better distribute these forces, it was necessary to fix the headrest at a plurality of points along the profile. On the contrary, thanks to the invention, each fixing plate 10a, 10b only requires fixing at two points by means for example of screws 17a, 17b cooperating with inserts 18a, 18b. Preferably, an insert such as 18b also allows

  the fixing of a bracket 19 for retaining the spring 15.

  Thus, the parts integral with the edge of the profile 2 are the fixing plates 10, the inserts 18 and the screws 17, the device for protection against false operations comprising the bracket 19, the spring 15, the movable element 14 and the retractable pin 11. The movable parts relative to the edge of the profile 2 are the fork 5 driven by the member 3 forming part of the external lock, the actuating blade 6 which transmits the movement to the blocks 7 carrying the hooks 8 and the organs contained in these blocks 7. Appropriate lights are provided in the plates 10 to allow the sliding of the blocks 7 and the hooks 8; these lights are crossed by rivets 20 which secure the blocks 7 hooks to the

actuating blade 6.

  Advantageously, provision is made to mount a blade-

  indexing spring 21 cooperating with an appropriate orifice of a plate 10 to hold the movable assembly comprising the actuating blade 6 and the members it

door in a fixed position.

  In the position of Figure 5, the curved end of the leaf spring 21 is engaged in the orifice 22 formed in the plate 10; while, when the moving element is moved in the direction of arrow 4, the leaf spring 21 is driven upwards and comes to bear on the bottom of the lumen 23 formed in the

brochure OB.

  The document FR 2.701.056 describes the operation of the screw 24 for adjusting the depth of the locking hook 8b. Compared to this document, the present invention comprises the improvement according to which the hook 8b can be quickly removed to mount the aforementioned moving element by one end of the profile 2 by loosening a needle screw 25 whose axis forms an angle

  with the hook adjusting direction.

  Thus, by loosening the needle screw 25, the mobile assembly is threaded through one end of the profile, the plates 10 are fixed by screwing the screws 17 into the inserts 18, which has the following purpose. effect of fixing the moving equipment; the retractable pin 11 is then screwed in place and the hooks 8a, 8b are positioned before tightening the needle screw (s)

holding hooks 8a, 8b.

  The needle screw 25 thus fulfills a double function: on the one hand it maintains the hook in position and, on the other hand, it appi that the hook on the adjustment screw 24 preventing any loosening after the

  hook depth adjustment is performed.

  The invention described with reference to a particular embodiment is in no way limited thereto, but on the contrary covers any modification of form and any variant embodiment of the invention in which the mobile assembly is contained inside the sliding profile of a sliding window, door or French window, the frame of which is made from a

hollow profile.
