Abstract

The plate for a door frame (15) comprising a slot for housing a locking part comprises a base plate (10) which is fixed to the frame. An insert (20), with a slot (21) extending between its walls, houses the locking part. The external faces of the insert walls fit the edges of the base plate opening and have fixing lugs (23). The walls and the fixing lugs pass between the base plate opening edges. The lugs are spring returned at right angles to a peripheral zone of the opening after passing the opening edges. The insert walls have a web (24) surrounding the slot which covers the base plate in the opening peripheral zone which is clamped between the web and the fixing lugs.

Description

The present invention relates to a keeper for a window frame, door, patio door or the like.

At all times, the strikes which equip the frames include a front face intended to be arranged in the front edge of the frame and pierced with a light adapted to accommodate a locking member of a fitting of an opening.

The fittings may be of the lock, cremone bolt, cremone bolt, cremone bolt, cremone bolt or similar type. The locking members are thus of very different types depending on the fitting (latch bolt, deadbolt, roller, rod end, etc.) and consequently require as many different types of strike as there are types of 'locking devices.

In addition, the median axis of the locking member, that is to say the axis passing through the middle of the locking member and parallel to the vertical median plane passing through the middle of the rebate of the upright or from the cross member on which the fitting is mounted, may be at a variable distance from the external face of the upright or from the cross member of the opening member on which the locking member is mounted.

Consequently, it is necessary to provide different types of keeper with different external dimensions, so that the light of the keeper can be positioned exactly in line with the locking member.

Finally, there are different kinds of keepers which depend on the method of fixing the keeper on the frame, (surface, by lardage, notching or fixing in a groove of the frame).

It is therefore understood that the variation of these three parameters: shape of the locking member, dimension between the median axis of the member and the plane of the outer face of the opening, and type of attachment of the keeper on the dormant, has the immediate effect of increasing the number of different strikes that should be manufactured and stored in order to satisfy all possible achievements.

The main object of the present invention is to provide a new keeper structure which makes it possible to considerably reduce the number of different keepers to be produced and stored.

The keeper covered by the invention makes it possible to equip a frame with windows, doors, French windows or the like and it includes a light for housing the locking member of a fitting of the opening.

According to the invention, the keeper is characterized in that it comprises a base adapted to be fixed to the frame and an insert comprising a slot adapted to house the locking member, the base comprising an opening forming a housing for the insert.

This two-part keeper makes it possible to limit the number of different parts to be provided: in fact, the base fixed on the frame is adapted to the type of fixing provided on the frame and the insert has a light whose shape is adapted to the locking member and at the level of the median vertical axis of this member.

For a given method of fixing the keeper to the frame, the base of the keeper is identical and only the insert is modified according to the shape and position of the member; lock.

Vice versa, for a predefined locking member, only the base is modified, the insert remaining unchanged, depending on the method of attachment provided on the frame.

The number of different parts to be produced is therefore considerably reduced taking into account the possible combinations between a base and an insert for producing the different types of keepers.

In addition, the fixing of the strike being carried out at the level of the base, only the latter must be made of a sufficiently strong material to obtain a solid fixing of the strike to the frame.

On the other hand, the insert can be made of a more economical material.

According to an advantageous version of the invention, the insert comprises walls between which the lumen extends, the external face of these walls conforming to the edges of the opening of the base and comprising at least one fixing lug, and the walls and the fixing lug (s) are adapted to pass between the edges of the opening of the base, the fixing lug (s) being resiliently brought back to the right of a peripheral zone of the opening after passing the edges of the opening.

The insert is thus simply fixed by snap-fastening in the opening of the base and requires no additional fixing means than the pins carried by the walls of the insert.

According to a preferred version of the invention, the lumen of the insert extends between two lateral walls adapted to be parallel to the external face of the upright or of the cross member of the frame equipped with the keeper, these walls having different respective thicknesses in a portion adjacent to the edges of the base opening.

The median axis of the lumen of the insert, parallel to the plane of the side walls, is thus offset relative to the median axis of the opening of the base.

It is thus possible, by modifying the thickness of one or other of the side walls of the insert, to make vary the position of the median axis of the light so as to place this light exactly in line with the locking members of the fitting mounted on the opening.

According to another aspect of the invention, a base is characterized in that it comprises, as accessories, a series of inserts adapted to be housed in the opening of the base, each insert having a light adapted to accommodate a locking member chosen from a latch bolt, a deadbolt, a roller, a rod end or the like.

Once the base chosen according to the method of fixing the strike on the frame, it suffices to fix in the opening of the base the appropriate insert that can accommodate the locking member.

According to an equivalent aspect of the invention, the insert of a keeper of the invention is characterized in that it comprises, as accessories, a series of bases having an opening adapted to accommodate the insert, each base having an external contour adapted to be fixed in a groove, a groove, a milling or the like of the front edge of a frame.

Referring firstly to FIG. 4, it will be recalled that the locking fittings which equip the doors, windows, French windows or the like, may include locking members which are very different from each other: deadbolt, U-bolt, roller, end of rods, ...

In the example of FIG. 4, the front edge 1 of an opening comprises a fitting box 2 housed in a groove 3 of the opening and which in this example comprises a latch bolt 4 and a deadbolt 5.

In addition to the diversity of the locking members, the dimension e of the median axis Δ with respect to the external face 6 of the upright or of the cross member of the leaf is variable and therefore necessitates adjusting the position of the light of each keeper so that it is located opposite the locking member which must be housed there.

According to the invention, and with reference first to Figure 1, the keeper includes a base 10 adapted to be fixed on the frame. To this end, the base 10 in this example comprises four through holes for fixing screws (not shown).

As illustrated in section in Figure 2, the base has a cross section substantially U-shaped, the base 12 of the "U" extending parallel to the front edge of the frame on which the keeper is mounted.

With reference to FIG. 8, it can be seen that the legs 13 of the base are designed to be housed in a groove 14 of the frame 15.

The base 10 also comprises an opening 16, illustrated in section in FIG. 3.

This opening 16 forms a housing for an insert 20 as illustrated in FIG. 5.

This insert 20 includes a lumen 21 adapted to accommodate a locking member.

In this example, the light 21 is capable of receiving a rod exit. However, it is easily understood that the shape of the light 21 could be modified to accommodate a locking roller, a deadbolt or a U-bolt.

The light 21 could also be capable of ensuring either use on the right or on the left, depending on the direction of opening of the opening.

In the case of a window with several leaves, the insert 20 can include as many lights 21 as leaves. It is thus possible to simultaneously ensure, for a window with two leaves, the locking of a semi-fixed leaf and of a mobile leaf.

As illustrated in the different views of FIGS. 6, 7, 9 and 10, the insert 20 comprises walls 22 between which the lumen 21 extends, the external face of the walls 22 matching the edges 17 of the opening 16 of the base 10 and comprising at least one fixing lug 23.

The walls 22 and the fixing lugs 23 are adapted to pass between the edges 17 of the opening 16 of the base 10, the fixing lugs 23 being resiliently returned to the right of a peripheral zone of the opening 16 after passing the edges 17 of the opening 16.

As illustrated in section in FIG. 8, when the insert 20 is in place in the opening 16 of the base 10, the lugs 23, four in number in this example, are arranged in line with the peripheral zone surrounding the opening 16 of the base 10, and are in engagement with the edges of the internal face 10a of the base 10.

In addition, the walls 22 of the insert 20 comprise a wing 24 substantially surrounding the lumen 21 of the insert 20 and adapted to cover the base 10 in the peripheral zone of the opening 16, this peripheral zone being pinched between the wing 24 and the fixing lugs 23.

This wing 24 makes it possible, in addition to fixing the insert 20 in the base 10, to hide the edges 17 of the opening 16 and to ensure sealing between these edges 17 and the walls 22 of the insert 20.

Preferably, the wing 24 is interrupted in line with the fixing lug (s) 23. This makes it easier to pinch the walls 22 of the insert 20 so as to bring them closer to one another during the introduction of the insert in the opening 16 of the base 10 and thus facilitate the passage of the fixing lugs 23 beyond the edges 17 of the opening 16.

The lumen 21 of the insert 20 extends between two side walls 22 which are adapted to be parallel to the outer face 19 of the upright (or of the cross member) of the frame 15 equipped with the keeper.

These walls 22 have different respective thicknesses in a zone 25 adjacent to the edges 17 of the opening 16 of the base 10.

The central axis 26 of the lumen 21 of the insert is thus offset with respect to the central axis 27 of the insert 20 itself, which is midway between the exterior faces of the side walls 22 in the zone 25 adjacent to the edges 17 of the opening 16.

This median axis 27 of the insert 20 is always coincident with the median axis 18 of the opening 16 of the base 10, while the median axis 26 of the lumen 21 of the insert 20 can be offset by one side or the other of the median axis 18 of the opening 16.

Thus, in FIG. 6, the median axis 26 is offset to the right of the figure relative to the median axis 27, while in another embodiment illustrated in FIG. 11, the median axis 26 of the light 21 is shifted to the left of the figure.

By simply modifying the thickness of the zone 25 of the side walls 22, different inserts are obtained from which one chooses the one whose median axis 26 of the lumen 21 can be placed opposite the median axis Δ of the locking member 4.5.

The side walls 22 are preferably joined in the bottom of the lumen 21 by a bottom wall 28 so that the cross section of the insert 20 has substantially the shape of "U".

For the sake of saving material, only the zone 25 of the walls 22 has greater or lesser thicknesses to modify the position of the median axis 26 of the lumen 21, the rest of the side walls 22 as well as the bottom wall 28 being of a thinner thickness.

Each base 10 can thus comprise as accessories, a series of inserts 20 adapted to be housed in the opening 16 of the base 10, each insert 20 having a slot 21 adapted to accommodate a locking member 4, 5 chosen from a latch bolt, a deadbolt, a roller, a rod end or the like.

In addition, each insert 20 has side walls 22 having in a zone 25 intended to be adjacent to the edges 17 of the opening 16 of the base 10, thicknesses normally different from one another. Of course, the set of inserts which can be used with a specific base includes an insert whose walls 22 have in the area 25 equal thicknesses respectively.

Vice versa, each insert 20 can comprise as accessories, a series of bases 10 having an opening 16 adapted to accommodate the insert 20, each base 10 having an external contour adapted to be fixed in a groove 14, a groove , milling or the like of the front edge of a frame 15.

Thanks to the invention, the proliferation of different kinds of waste is reduced.

Of course, the invention is not limited to the embodiment described above and numerous modifications can be made to it without departing from the scope of the invention.

Thus, the keeper of the invention can equip either an upright or a cross member of a frame.

The same base could possibly include several openings 16 adapted to each house a particular insert 10.
