Description

DESCRIPTION

Hinge for a window or door with hinge leaf with associated accessory with adjustable thickness for lateral adjustment of the window or door

The invention relates to a hinged window or door with an associated accessory with adjustable thickness for lateral adjustment of the window or door.

The rest of the description will focus primarily on windows, with the knowledge that this also applies to doors and vice versa.

To mount a rotating window sash on the fixed window frame, hinges are used, which, as is known, are formed by two hinge leaves with which the hinge is attached to the sash and the fixed frame, by means of which The hinge parts are hingedly connected by a hinge pin.

When mounting the sash in the fixed frame, it is important that the lateral position of the sash in the fixed frame can be adjusted so that the door or window can be easily opened and closed without snagging and the closing mechanism can be easily operated without pinching.

It is already known from BE 1,016,414 and BE 1,022,089, corresponding to EP 2,993,290, that an accessory with an adjustable thickness can be used for this, which when mounting the window or door is fixed between the hinge and the profile of the window or door to which the hinge is fixed, in particular between the profile and the hinge leaf with which the hinge is mounted to the profile.

This accessory of the known type is composed of two plate-shaped parts which are fixed against each other on one side and which are provided on this side with a wedge-shaped relief with wedge-shaped elements which are so that when Both parts with their wedge-shaped teeth move relative to each other in the longitudinal direction of the teeth, the plate-shaped parts move apart, so to speak, so that the thickness of the fixture can be adjusted.

In this way, the thickness of the fixture is adjustable between a minimum thickness at which the wedge-shaped teeth interlock maximally, for example, along the entire height or depth of the teeth, and a maximum thickness at which which the teeth interlock less deeply.

In known embodiments, the front contacting sides of the hinge leaf and the fixture are flat to allow them to move relative to each other for lateral adjustment.

In that case, the minimum total thickness occupied by the hinge sash together with the accessory in the mounted condition in the recess between the fixed frame and the window sash is equal to the sum of the thickness of the hinge sash and the aforementioned thickness accessory minimum.

The greater the minimum overall thickness of the hinge leaf with attachment, imposed by the required strength of the hinge, the smaller the lateral adjustment distance available for a given depth of recess.

Conversely, the smaller the available recess depth for a given fit distance, the lower the minimum overall thickness and therefore the lower the thickness of the hinge leaf and/or fitting, which will weaken the hinge and will reduce the maximum permissible load of the hinge, for example due to the weight of the window sash.

In known hinges this results in the disadvantage that in the design a choice needs to be made between a greater adjustment distance or a stronger hinge or a compromise between both.

This difficult choice occurs mainly in hinges with a shaft that is visible on the outside of the window and a fixation of the hinge sashes that in the closed position of the window is invisible in the groove between the fixed frame and the sash.

With this type of hinge, the problem is that there is often not enough space for a sufficiently strong hinge, i.e. combined with the desired lateral adjustment range.

The purpose of the present invention is to offer a solution for one or more of the drawbacks and problems mentioned above and others.

To this end, the invention relates to a hinge for a window or door with a hinge leaf with an associated accessory intended to be mounted between the hinge leaf and a profile of the window or door to which the hinge leaf is fixed. , so that the thickness of the accessory is adjustable for lateral adjustment of the window or door, said accessory is composed of two essentially plate-shaped parts, respectively a first part which in the assembled condition is in contact with the sash hinge and a second part, said parts which in use are fixed against each other on one side and are provided on said sides with complementary serrations that interlock, in such a way that when both parts slide in a direction of longitudinal sliding along along the serrations in one or another direction relative to each other, the thickness of the accessory increases or decreases in a direction perpendicular to the hinge leaf, characterized in that in the assembled condition of the hinge with the accessory between the hinge leaf and the profile, the hinge leaf and the first plate-shaped part of the accessory in contact therewith are provided on the facing sides with complementary protuberances and recesses with which they interlock, where the recesses in the first part of the accessory are They provide within the thickness of the teeth of the teeth of the first part.

The hinge leaf and the locking accessory cause, according to the invention, the minimum total thickness of the hinge leaf together with the accessory in the assembled condition to be less than in known hinges which in the assembled condition are mounted against each other for a flat side.

This means that, compared to known hinges with accessory, for an unchanged adjustment range of the accessory thickness, more space remains in the recess between the fixed frame and the window sash, so that there is more space to be able to apply a thicker and therefore more resistant hinge.

In the same way, for an unchanged thickness of the hinge leaf, an accessory with a larger adjustment range can be applied.

The freed up space can, of course, also be used in favor of a stronger hinge leaf along with a greater adjustment range.

Preferably, the protuberances and depressions are formed as ribs and grooves extending transversely perpendicular to the sliding direction of the fixture and preferably across the entire width of the hinge leaf and fixture.

Preferably, the protuberances and recesses interlock tightly without play or with only limited play in the sliding direction, so that the hinge leaf and the first part of the fitting cannot unintentionally move relative to each other during the lateral adjustment of the position and in relation to the sash of the fixed window frame.

According to the invention, the recesses in the first part of the accessory are provided within the thickness of the teeth of the gearing of the first part.

The greatest space gain in favor of hinge strength or adjustment range can be obtained with an accessory, where the height of the serrations of both plate-shaped parts is approximately equal to or slightly less than the thickness of each part taken separately.

With the intention of better showing the characteristics of the invention, a preferred embodiment of a hinge with associated accessory according to the invention is described by way of example, without limitation, with reference to the attached figures:

Figure 1 schematically shows a perspective view of a section of an open window that is equipped with a hinge and an accessory as known in the past;

Figure 2 shows a cross section along line II-II in Figure 1, but in a closed window condition;

Figure 3 shows a cross section along line III-NI in Figure 2;

Figure 4 shows a cross section like that of Figure 3, but for a different fitting configuration of the fixture;

Figure 5 shows a perspective view of a hinge with accessory according to the invention in a partially disassembled condition;

Figure 6 shows a cross section like that of Figure 4 but for the modality of Figure 5;

Figure 7 shows the cross section of Figure 6 in a different fitting configuration of the accessory, Figure 8 shows a cross section similar to that of Figure 6, but for an alternative embodiment of the invention.

Figure 1 shows a section of a window 1 containing a profile 2 of the fixed frame of the window 1 and a profile 3 of the window sash 1, said profiles 2 and 3 are articulatedly connected by a hinge 4 which is composed of two hinge leaves 6 and 7 that are connected relative to each other by a hinge pin 8 at a joint 5 of the hinge.

Hinge 4 is attached to profiles 2 and 3 by screws 9 which are threaded through passages in screw blades 7 and 8 in profiles 2 and 3 mentioned above.

In this case, the window is of the type in which the joint 5 with the hinge pin 8 of the hinges 4 is visible on the outside of the window 1 and the fixing of the hinge leaves 6 and 7 to the profiles 2 and 3 in a closed window 1 is hidden in the recess 10 or closed space between profile 2 of the fixed frame and profile 3 of the sash.

In the example of Figure 1, the hinge leaf 7 is provided with a recess for the second hinge leaf 6 in the closed condition of the hinge 4.

The hinge 4 contains an essentially flat-shaped accessory 11 of the known type which in this case is mounted between the hinge leaf 6 and the profile 3.

The known accessory 11 is composed of two essentially plate-shaped parts 11a and 11b, respectively a first part 11a which in the assembled condition is in contact with the hinge leaf 6 and a second part 11b with which the accessory 11 is fixed against profile 3.

In use, the two parts 11a and 11b are fixed against each other on one side, where said sides are provided with complementary wedge-shaped teeth, respectively 11c and 11d, which are such that when both parts 11a and 11 are slide in a longitudinal sliding direction (X-X') along the teeth in one direction or another relative to each other, the adjustable thickness D of the accessory 11 increases or decreases in a direction perpendicular to the plane of the sheet of hinge 6 or, in other words, perpendicular to the flat bottom of the accessory 11.

In the example, the accessory is oriented in such a way that the sliding direction X-X' is parallel to the longitudinal direction of the profiles 2 and 3 and therefore also parallel to the axis of the hinge pin 8.

Figure 4 shows a situation in which the teeth of the two parts 11a and 11b of the accessory 11 interlock to the maximum, resulting in a minimum thickness Dmin of the accessory 11, while in the situation of Figure 3 the parts 11a and 11b slide maximally in the sliding direction of sliding X-X' to have a sufficient support surface between the two.

This results in a setting range AD = Dmax - Dmin.

The minimum thickness Dmin of the accessory 11 is determined mainly in the case of the figures by the height or thickness of the teeth 11c and 11d measured in a direction perpendicular to the plane of the lower part of the accessory 11.

By adjusting the thickness D of the accessory 11 it is possible to adjust the lateral distance E of the profile 3 of the sash with respect to the profile 2 of the fixed frame, as indicated with the double arrow P in Figure 2, and this between:

- a minimum distance Emin, as shown in Figure 4,

- and a maximum distance Emax as shown in Figure 3,

where Emax is equal to the joint maximum total thickness of the hinge leaf 6 and the accessory 11:

Emax = Dmax F

The maximum total thickness Emax of the hinge leaf 6 and the accessory 11 is limited by the available space 10 between profile 2 of the fixed frame and profile 3 of the leaf, more specifically the available distance A between profiles 2 and 3, so in the design with the known applications of Figures 2 to 4 a choice must be made between:

- limiting the maximum thickness Dmax of the accessory 11 at the expense of the adjustment range of the accessory 11;

- limiting the thickness F of the hinge leaf 6 at the expense of the strength of the hinge leaf 6 and therefore the load capacity of the hinge 4;

- a combination of them.

The invention aims to create more space in favor of a greater adjustment range AD and/or a greater thickness F of the hinge leaf 6.

This is achieved by a combination of a hinge leaf 6 with an accessory 11 according to the invention, as shown in Figures 5 to 8, so that in this case, in the assembled condition of the hinge 4, the hinge leaf 6 and the first plate-shaped part 11a of the accessory 11 in contact therewith interlock over a certain depth K, as shown, unlike the situation known from Figures 1 to 4 in which the hinge leaf 6 and The accessory 11 are fixed against each other on a flat side.

In the embodiment of Figures 5 to 8, this is done by providing the hinge leaf 6 and the first part 11a of the fitting 11 on opposite sides with rib-shaped protuberances 12 that fit into the complementary recesses 13 in the form of slots in the first part 11a of the accessory 11.

The ribs 12 and the slots 13 extend transversely in a Y-Y' direction perpendicular to the X-X' sliding direction of the fixture 11 along the width of the hinge leaf 6 and the fixture 11.

In the example, the ribs 12 have a thickness corresponding to the thickness K of the overlap section between the hinge leaf 6 and the accessory 11 and a width B practically corresponding to the width of the slots 13.

The slots 13 in the accessory 11 are provided in the material of the teeth of the teeth 11c of the first part 11a of the accessory, more specifically within the thickness or height of said teeth 11c, so that preferably a slot 13 is provided in each tooth of the 11c tooth.

Preferably, the thickness of the teeth 11c and 11d of both plate-shaped parts 11a and 11b, except for a small thickness, is approximately equal to the thickness of each part separately and preferably approximately equal to the minimum thickness Dmin of the fixture 11.

The rib-like protrusions 12 in Figure 6 create a bulge and therefore a reinforcement of the hinge leaf 6, at least to the extent that the protrusions create an additional thickness K in relation to the hinge leaf 6 of Figure 4 without protuberances.

The recesses 13 in the fitting 11 create a weakening of the fitting 11 in case of unchanged thickness Dmin, but in combination with the reinforced hinge leaf 11 sufficient support is obtained.

For the same minimum thickness Dmin of the accessory 11 and the same minimum total thickness Emin, the invention still offers the advantage of a reinforced hinge 4.

Figure 8 shows an alternative embodiment in which, in this case, the minimum total thickness Emin of the hinge leaf 6 and the accessory together is the same as in Figure 4, but this time in combination with an accessory 11 with a greater minimum thickness Dmin and with a greater adjustment range AD, this slightly at the expense of the strength of the hinge leaf 11 because in this case the protuberances 12 are obtained by a locally reduced thickness of the hinge leaf 6 in relation to the Figure 4.

Preferably, a guide, not shown in the figures, is provided in the sliding direction X-X' of the accessory 11, said guide being provided at the level of the hinge 4 or the accessory 11 or the profile 2.

According to one embodiment, which is not shown, the accessory 11 can be provided with several complementary teeth 11c and 11d that extend transversely of the accessory 11 side by side in the sliding direction X-X' and that slide longitudinally X-X' an in relation to the other over a distance that is less than the pitch of the teeth 11c, 11d, so that a guide mentioned above can be made at the level of the accessory 11 itself.

It is understood that the hinge leaf 6 and the accessory 11 may be provided with passages for the aforementioned screws 9 in the form of slotted holes to allow a mutual displacement of the parts 11a and 11b of the accessory 11 relative to each other during adjustment side of the leaf.

It is also clear that the protuberances 12 and the recesses 13 do not necessarily have to be executed as ribs and grooves, but can have any form of engagement.

Needless to say, the accessory can also be mounted on profile 2 of the fixed frame instead of profile 3 of the sash.

The present invention is in no way limited to the modality described as an example and shown in the figures, however, said hinge with the associated accessory can be made according to different variants, without going beyond the scope of the invention as defined in the figures. claims.
