Description

Hinge for a window or door with hinge leaf with associated attachment with adjustable thickness for lateral adjustment of the window or door, the window or the door, 16 For the rest of the description, we will mainly talk about windows, knowing that this also applies to doors and vice versa.

IS For mounting a revolving sash of a window in a fixed frame of the window, use is made of hinges which, as is known, are formed by two hinge leaves with which the hinge is attached to the sash and the fixed frame, whereby the hinge parts are hinged to each other. are connected by means of 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 in order to be able to open and close the door or window easily without slings and to operate the closing mechanism without twisting. It is already known from BE 1.016.414 and BE 1.022.083, M coc corresponding to EP 2.993.290, that an attachment with adjustable thickness can be used for this purpose, which is fitted between the hinge and the profile of the window or door on which the hinge is mounted, more specifically between the profile and hinge leaf with which the hinge is mounted on the profile.

This accessory of the known type is composed of two plate-shaped parts placed one side to the other and each of which is provided on this side with a wedge-shaped relief with wedge-shaped elements such that, when both gels with their wedge-shaped Lands relative to are shifted together in the longitudinal direction of the teeth, the plate-shaped parts are, as it were, moved apart, so that the thickness of the attachment can be regulated.

The thickness of the attachment can thus be adjusted between a minimum thickness at which the wedge-shaped teeth interlock maximally, for example over the entire height or depth of the Landen, and a maximum thickness at which the teeth interlock less deeply.

In the known embodiments, the contact sides of the hinge leaf and of the attachment facing each other are flat in order to allow a shift relative to each other for lateral adjustment.

In that case, the minimum total thickness taken up by the hinge leaf together with the fitting piece in the mounted position in the rebate between the fixed frame and the sash of the window is equal to the son of the thickness of the hinge leaf and the aforementioned minimum thickness of the attachment. 3 The greater the minimum total thickness of the hinge leaf with attachment imposed by a required rigidity of the hinge, the smaller the available spacing of the lateral adjustment for a given rebate depth.

Conversely, the smaller the available rebate depth FOR a given line spacing, the smaller the minimum overall thickness and therefore the smaller the thicknesses of the hinge leaf and/or of the attachment and therefore the weaker the hinge and the resulting maximum allowable load of the hinge. hinge, for example due to the weight of the wing of the window. With the known hinges, this results in the disadvantage that a choice has to be made during design between a larger line spacing or a firmer hinge or a compromise between both. This difficult choice mainly occurs with hinges 23 with an axis that is visible on the outside of the window and an attachment of the hinge leaves invisible when the window is closed in the rebate between the fixed frame and the sash. The problem with this type of hinges is that there is often too little space for a sufficiently strong hinge, combined with the desired lateral adjustment range.

The present invention aims to provide a solution to one or more of the aforementioned and other drawbacks and problems. Le Dieden. To this end, the invention relates to a hinge for a window or door with a hinge leaf with associated accessory which is intended to be mounted between the hinge leaf and a profile of the window or door to which the hinge leaf is attached, the thickness of the attachment being adjustable for lateral adjustment of the window or door, which attachment is composed of two substantially plate-shaped parts, respectively a first part that is in mounted condition is in contact with the hinge leaf and a second part, which parts are arranged with one side against each other in use and which are provided on these sides with interlocking complementary teeth which are such that when both gels in a longitudinal sliding direction of the gears are shifted in some sense relative to each other, the thickness of the fitting increases or decreases in a direction perpendicular to the hinge leaf, whereby in the mounted condition of the hinge with the fitting between the hinge leaf and the profile, the hinge leaf and the plate-shaped first part of the fitting in contact with it rest on the opposite sides are provided with projections and 39 complementary recesses with which they interlock,

characterized in that the recesses in the first part of the attachment are recessed within the thickness of the teeth of the teeth of the first part.

Because the hinge leaf and the support piece interlock, it is achieved according to the invention that in mounted condition the minimum total thickness of the hinge leaf together with the stub piece is smaller than with the known hinges which are mounted with one flat side against each other in mounted condition.

This means that, compared to the known hinges with attachment, for a constant range of adjustment of the thickness of the attachment, more space remains in the rebate 18 between the fixed frame and the sash of the window, so that there is more room to fit a thicker and thus to be able to fit a firmer hinge. In the same way, for a constant thickness of the hinge leaf, an attachment with a larger adjustment range can be applied. The freed space can of course also be used for the benefit of a firmer hinge leaf together with a larger adjustment range, Preferably, the projections and recesses are formed as ribs and grooves extending widthwise perpendicular to the sliding direction of the attachment and preferably over the full width of the hinge joint and of the attachment. Preferably, the protrusions and recesses interengage snugly without play or with only a slight play in the sliding direction, so that the hinge leaf and the first deal of the attachment cannot unintentionally shift relative to each other during the lateral adjustment of the position and of the wing of the fixed frame of the window.

It According to the invention, the recesses in the first part of the sleeve piece are recessed within the thickness of the countries of the teeth of the first part.

The greatest space gain in favor of the strength of the hinge or the adjustment range can be obtained with a zero piece of which the height of the teeth of the two plate-shaped parts is approximately equal or slightly smaller than the thickness of each part taken separately. insight to better demonstrate the features of the invention, a preferred embodiment of a hinge with accompanying accessory according to the invention is described below by way of example without any limiting character, with reference to the accompanying drawings, in which: figure 1 schematically and in perspective shows a part of depicts an open window equipped with a hinge and a fitting as known from the past; figure £ represents a section according to line II-IT in figure 1 , but in a closed position of the window:

figure 3 shows a cross-section according to line III-III in figure 2: figure 4 shows a cross-section like that of figure 3, but for a different adjustment position of the attachment; figure 5 represents a perspective view of a hinge with accessory according to the invention in partly disassembled condition; figure 6 shows a cross-section like that of figure 4 but for the embodiment of figure 5; figure 7 shows the cross-section of figure & in another sealing position of the attachment, figure B shows a cross-section like that of figure 6 for an alternative embodiment of the invention.

Figure 1 shows a part of a window 1 comprising a profile 2 of the fixed frame of the window 1 and a profile 3 of the sash of the window 1, which profiles Z and 3 are hingedly connected to each other by means of a hinge 4 which is composed of two hinge leaves 6 and 328 7 which are connected to each other by means of a hinge pin 8 at the location of a node 5 of the hinge. The hinge 4 is attached to the profiles 2 and 3 by means of screws 3 which are screwed into the aforementioned profiles 2 and 3 through passages in the screw blades 7 and 8. The window in this case is of the type where the knot 5 with the hinge pin 8 of the hinges 4 is visible on the outside of the window 1 and the attachment of the hinge plates © and 7 to the profiles 2 and 3 in the case of a closed window 1 is hidden in the rebate 12 or enclosed space between the profile 2 of the fixed frame and the profile 3 of the vent.

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

The hinge 4 comprises a substantially plate-shaped attachment 11 of the known type, which in this case is mounted between the hinge leaf 6 and the profile 3. The known attachment 21 is composed of two mainly plate-shaped parts IIIa and IIb, respectively a first part Ilia. which, in mounted condition, is in contact with the hinge leaf 6 and a second part 11b with which the attachment 13 is arranged against the profile 3.

In use, both parts 11a and 11b are arranged side by side, these sides being provided with intermeshing complementary wedge-shaped teeth, 11c and 11d, respectively, which are such that when both parts 11a and Ti are in a longitudinal sliding direction ( K-X'} of the cants are shifted in one sense or another relative to each other, the adjustable thickness D of the attachment 11 increases or decreases in a direction perpendicular to the plane of the hinge leaf 6 or, in other words, perpendicular to the flat underside of the zero piece 11.

a In the example, the fitting is oriented in such a way that the sliding direction X-X' is parallel to the longitudinal direction of profiles 2 and 3 and therefore also parallel to the axis of hinge pin 8. Figure à shows a situation in which the serrations of the two parts 11a and 11b of the attachment 11 interlock maximally, resulting in a minimum thickness Dmin of the attachment 11, while in the situation of figure 3 the parts 11a and 11b maximally interlock in the sliding direction X-X' with respect to are shifted from each other, resulting in a maximum thickness Dmax of the attachment 11 at which the serrations 11c and member of both parts must still overlap each other sufficiently in the sliding direction X-X' to have a sufficient support plane. This results in a control range AD = Dmax — Dune, The minimum thickness Dmin of the attachment 11 in the case of the figures is mainly determined by the height or thickness of the teeth lic and ild measured in a direction perpendicular to the plane of the underside of the attachment 11.

By adjusting the thickness D of the attachment 11, it is possible to adjust the lateral distance E of the profile 3 of the leaf in relation to the profile 2 of the fixed frame, as indicated by the double arrow P in Figure 2, and this between: 38

= no minimum distance Emin, as in figure 4, — and a maximum distance Emax as in figure 3, where Emax is equal to the joint maximum total thickness of the hinge leaf 6 and the attachment 11: Emax = Dmax + F For the maximum total thickness Emax of the hinge leaf 6 and the support piece 11, one is limited by the available space 10 between the profile 2 of the fixed frame and the profile 3 of the wing, more specifically the available distance A between the profiles 2 and 3, which means that when designing with the known applications of figures 2 to 4, a choice must be made between: = either limiting the maximum thickness Dmax of the attachment 11 at the expense of the recline range of the attachment 211: 2G « just limiting the thickness F of the hinge leaf & at the expense of the strength of the hinge leaf € and thus of the bearing capacity of the hinge 4; = or a combination thereof, The invention is intended to create more space in favor of a larger adjustment range AD and/or a larger thickness F of the hinge plate 6,

This is achieved by a combination of a hinge leaf € with an accessory 11 according to the invention as shown in figures 5 to 8, wherein in this case, in the mounted condition of the hinge 4, the hinge leaf 6 and the plate-shaped first part in contact therewith. part 11a of the attachment 11 interlock over a certain depth K as shown, this in contrast to the known situation of figures 1 to 4 in which the hinge leaf 6 and the attachment 11 are arranged with a flat side against each other.

In the embodiment of figures 5 to 8 this is achieved in that the hinge leaf 6 and the serst part 11a of the attachment 11 are provided on the facing sides with protrusions 12 in the form of ribs which fit into complementary owl recesses 13 in the shape of grooves in the first part 11a of the attachment 11, The ribs 12 and grooves 13 extend in width in a direction Y-Y' perpendicular to the sliding direction X-X" of the attachment 11 across the width of the hinge section 6 and of the attachment 11. In the example, the ribs 12 have a thickness corresponding to the thickness K of the overlapping part between hinge leaf & and attachment 11 and a width B approximately corresponding to the width of the grooves 13. The grooves 13 in the attachment 11 are recessed in the material of the teeth of the teeth 11c of the serste 34 des lia of the attachment, in particular within the thickness or height of this toothing llc, preferably i A groove 13 is provided in each Land of the toothing llc. Preferably, the thickness of the teeth lic and 110 of the two clate-shaped parts 11a and lib, with the exception of a small thickness, is approximately equal to the thickness of each part taken separately and preferably approximately equal to the minimum thickness Dmin of the attachment il .

The ribs 12 in the form of ribs in figure 6 provide a thickening and thus a reinforcement of the hinge leaf 6, at least insofar as the projections provide an extra thickness K compared to the hinge leaf 6 of figure 4 without projections. The recesses 13 in the attachment 11 weaken the attachment 11 at constant thickness Dmin, but in combination with the reinforced hinge leaf 11 sufficient support is still obtained.

For the same minimum thickness Dmin of the fitting 11 and the same minimum total thickness Emin, the invention nevertheless 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 attachment together is the same as that of figure 4, but this time in combination with an attachment 11 with a greater minimum thickness [min 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 protrusions 12 have been obtained due to the locally reduced thickness of the hinge leaf 6 compared to figure 4. A guide, not shown in the figures, is preferably provided in the sliding direction X-X' of the accessory 11, which guide may be provided at the location of the hinge à or of the accessory 11 or of the profile 2. According to an embodiment (not shown), the accessory li can be provided with several complementary teeth llc and lid which extend side by side in the width of the attachment 11 in the sliding direction K-X' and which are relative to each other in the longitudinal direction X- X' are offset by a distance smaller than the pitch of the teeth 11c, 11d, so that a leading guide at the location of the attachment 11 itself can be re-established.

It is clear that the hinge blade 6 and the attachment 11 can be provided with passages for the aforementioned screws 3 in the form of slip grooves in order to allow a relative displacement of the parts 111a and 115 of the attachment 11 during the lateral adjustment of the wing. relative to each other.

It is also clear that the protrusions 12 and recesses 13 need not necessarily be formed as ribs and grooves, but can have any interlocking shapes,

Ld It goes without saying that the accessory 11 can also be mounted on profile 2 of the fixed frame instead of on profile 3 of the leaf,

The present invention is by no means limited to the embodiment described above and shown in the figures, but such a hinge with associated accessory can be realized in various variants without departing from the scope of the invention.
