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 frames, doors, patio doors or similar.

From time immemorial, the strikes which equip the frames include a front panel intended to be arranged in the front edge of the frame and pierced with a light adapted to accommodate a locking member of a opening hardware.

The fittings can be of the lock type, cremone bolt, bolt lock, bolt lock, bolt headrest or the like. The locking members are thus very different types depending on the fitting (U-bolt, deadbolt, roller, end of rod ...) and therefore require as much different types of strike there are types locking devices.

In addition, the median axis of the organ of locking, i.e. the axis passing through the middle of the locking member and parallel to the median plane vertical passing through the middle of the rebate of the upright or cross member on which the fitting, can be at a variable distance from the face exterior of said upright or said cross member of opening it.

Therefore, it is necessary to plan different types of exterior dimensions different, so you can position the light of the waste exactly to the right of the organ of locking.

Finally, there are different kinds of strikes which depend on how the strike is attached to the dormant, (applied, by lardage, notching or fixing in a groove of the frame).

We therefore understand that the variation of these three parameters: shape of the locking member, dimension between the median axis of the organ and the plane of the face opening of the sash, and type of strike attachment on the frame, has the immediate effect of multiplying the number of different strikes to be made and store in order to satisfy all possible achievements.

We know, from DE-A-1 901 834, a keeper for a window, door, patio door or window frame analogous, comprising a base adapted to be fixed on the frame and an insert comprising a light adapted to receive a locking member of a fitting of a opening, the base comprising an opening forming insert housing, the insert comprising two walls lateral adapted to be parallel to the face outside of the upright or the cross member of the frame equipped with the strike plate and between which extends said light, the outer face of the walls matching the edges of the base opening and comprising at least a fixing lug, and said walls and the one or more fixing lugs being adapted to pass between the edges of the base opening, the lug (s) of fixing being recalled elastically to the right of a peripheral area of the opening, after exceeding edges of the opening, the walls of the insert having a wing substantially surrounding the lumen of the insert and adapted to cover the base along the edges of the opening.

The problem underlying this invention consists in proposing a method of fixing a keeper on a prefabricated tiled partition with a concrete core. For avoid drilling screw holes near the edges of the notch intended to receive a strike, the solution proposed is to set up a box of reservation placed against the core of the profile forming the bulkhead frame and attached to a rib of this profile, and pour the concrete around this box and on it inside the frame.

The keeper is fixed inside the box, by snap-fastening or screwing, at the precise place provided for said strike.

This document does not mention the problems described above and does not describe or suggest any solution to these problems.

The main object of the present invention is to propose a new strike structure which allows drastically reduce the number of different strikes to make and store.

According to the present invention, the keeper of the type aforementioned is characterized in that the side walls of the insert have, at least in an area adjacent to the edges, respective predetermined thicknesses of so that the median axis of light is shifted by a predetermined distance to one side or the other of the median axis of the insert so as to be in look of the central axis of the locking member corresponding.

This two-part keeper limits the number of different rooms to provide: indeed, 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 organ.

For a given method of fixing the keeper on the frame, the strike plate is identical and only the insert is modified according to the shape and position of the locking member.

Vice versa, for a locking device predefined, 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 possible combinations between a base and an insert to make the different types of strikes.

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

However, the insert can be manufactured in one more economical material.

The insert is thus simply fixed by "clipping" into the opening of the base and does not require no additional fixing means other than pins carried by the walls of the insert.

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

According to another aspect of the invention, a strike system comprising a strike of the aforementioned type comprising at least one base and one insert, is characterized in that said system comprises a series inserts, each insert of said series being adapted to be inserted into the opening of the base and comprising a light adapted to receive said organ of lock, and in that each of the inserts of the series of inserts with walls of respective thickness predetermined such as the median axis of light of said insert is offset from the median axis of said insert of a predetermined distance which is different from that, and / or is shifted to a side that is different of that, corresponding to any of the others series inserts.

We can thus, by modifying the thickness of one either side of the insert, do vary the position of the mid-axis of the light from so as to have this light exactly at the right of the locking member of the fitting mounted on opening it.

Once the base has been selected according to the mode of fixing the strike on the frame, just fix in the opening of the base the appropriate insert which can house the locking member.

Referring first to Figure 4, we remember that the locking fittings fitted opening doors, windows, French windows or analogs, may have locking members very different from each other: deadbolt, deadbolt U-turn, roller, end of lever rods, ...

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

In addition to the variety of locking devices, the dimension e of the median axis Δ relative to the face exterior 6 of the upright or of the cross member of the opening is variable and therefore requires adjusting the position of the light of each keeper so that it is located opposite the locking member which must stay there.

In accordance with the invention, and with reference to all first in 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 holes for passage for fixing screws (not shown).

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

Referring to Figure 8, we see that the legs 13 of the base are provided to be housed in a groove 14 of the frame 15.

The base 10 further comprises an opening 16, illustrated in section in Figure 3.

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

This insert 20 includes a light 21 adapted to house a locking member.

In this example, the light 21 is susceptible to receive a rod exit. But we understand easily that the shape of the light 21 could be modified to accommodate a locking roller, a bolt deadbolt or a latch bolt.

Light 21 could also be suitable for ensure either right-hand or right-hand use left according to the opening direction of the opening.

In the case of a multi-leaf window, the insert 20 can include as many lights 21 as there are leaves. We can thus ensure simultaneously, for a double-leaf window, locking one leaf semi-fixed and a movable leaf.

As illustrated in the different views of Figures 6, 7, 9 and 10, the insert 20 includes walls 22 between which the light extends 21, the face outer 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 recalled elastically to the right of a peripheral area of opening 16 after passing edges 17 of opening 16.

As illustrated in section in Figure 8, when the insert 20 is in place in the opening 16 of the base 10, the pins 23, four in number in this example, are arranged to the right of the surrounding peripheral area the opening 16 of the base 10, and are engaged with the edges of the inner face 10a of the base 10.

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

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

Preferably, the wing 24 is interrupted at the right of the fixing lug (s) 23. This allows pinch the walls 22 of insert 20 more easily to bring them closer to each other during the introduction of the insert in the opening 16 of the base 10 and of thus facilitate the passage of the fixing lugs 23 beyond edges 17 of 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 fitted with the keeper.

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

The median axis 26 of the lumen 21 of the insert is thus offset from the center line 27 of the insert 20 itself, which is halfway between the outer faces side walls 22 in the zone 25 adjacent to the edges 17 of opening 16.

This median axis 27 of the insert 20 is always coincides with the median axis 18 of the opening 16 of the base 10, while the median axis 26 of the light 21 insert 20 can be shifted to one side or the other of the central axis 18 of the opening 16.

Thus, in FIG. 6, the median axis 26 is offset to the right of the figure with respect to the axis median 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 changing the thickness of the zone 25 of the side walls 22, inserts are obtained different among which we choose the one whose axis median 26 of light 21 can be compared to the median axis Δ of the locking member 4.5.

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

For the sake of saving material, only the area 25 of the walls 22 has more or less thicknesses important to modify the position of the central axis 26 light 21, the rest of the side walls 22 as well that the bottom wall 28 being of a thickness more slim.

Each base 10 can thus understand as as accessories, a series of 20 inserts adapted to be housed in the opening 16 of the base 10, each insert 20 having a light 21 adapted to house a lock 4, 5 chosen from a latch bolt, a deadbolt, a roller, a rod end or similar.

In addition, each insert 20 has side walls 22 presenting in a zone 25 intended to be adjacent at the edges 17 of the opening 16 of the base 10, thicknesses normally different from each other. Of course, the set of inserts usable with a fixed base includes an insert whose walls 22 have in the zone 25 equal respective thicknesses.

Vice versa, each insert 20 can include as accessories, a series of bases 10 having a opening 16 adapted to accommodate 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 edge front of a frame 15.

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

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

Thus, the keeper of the invention can equip indifferently an amount or a cross member of a frame.

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