BE2017 / 5051

Sliding door or sliding window and guides applied.

The present invention relates to a sliding door or sliding window with at least two wings which can slide relative to each other and which can be moved parallel to each other in front and behind each other in two different planes.

In what follows, whenever it concerns a sliding door, it will equally apply to a sliding window.

The expression that the wings are slid relative to each other does not mean that the wings must necessarily each be slid separately, but also includes the situation where, for example, one wing is fixed and the other wing is slid relative to the fixed wing.

The wings of the sliding door are composed of profiles of aluminum or the like that together form a frame

shapes with vertical styles and horizontal lines where a panel out glass or of such in can become 25 applied. Known by this type of sliding doors or sliding windows overlap the wings together with a so-called

center post of each of the wings, with the exterior post hiding behind the center post of the other wing, given the center post of one wing.

BE2017 / 5051

In the design, the sliding door has been developed in such a way that there is a nominal transverse distance of, for example, 12 millimeters between the facing sides of the overlapping center posts to have enough space to provide sealing profiles between the center posts to ensure sealing against wind and rain. The transverse distance is measured perpendicular to the sliding direction, in particular perpendicular to the plane of the panels of the wings.

The sealing profiles are provided with a lip protruding laterally in the sliding direction of the wings at a distance from the mutually facing sides of the center posts, whereby the sealing profiles hook with their lips behind each other with a closed sliding door, thereby sealing on the other center post press to form a seal over the entire height of the center posts.

In the design, sealing profiles are chosen with a thickness smaller than the aforementioned imposed nominal transverse distance between the center posts in the closed position.

For a nominal transverse distance of typically 12 millimeters, for example, sealing profiles with a thickness of 8 millimeters are chosen and lips that hook in the nominal closed state of the sliding door with a clearance of, for example, 3 millimeters.

BE2017 / 5051

This gives, based on the nominal closed position, a limited freedom of movement in the transverse direction of the center posts with respect to each other, which is necessary, for example, to accommodate manufacturing tolerances or to allow mutual movements due to the wind or to allow mutual movements. resulting from differential elongation or shortening of the center posts on the outside of the sliding window from the inside.

For example, this can be the result of a temperature difference between the outside and the inside, with the result that the center posts can bend outwards or inwards, depending on whether the temperature in the outside is greater in the summer than inside or vice versa in the winter than in the interior.

Due to the deflection, the mutual displacement of the center posts relative to each other is greater at half the height of the center posts than at the top and bottom.

Due to the specific shape and dimensions of the sealing profiles, however, the mutual freedom of movement of the center posts in the transverse direction is rather limited, whereby the transverse distance between the facing sides of the center posts in the given example of dimensions is limited between a minimum required cross distance of 8 millimeters. up to a maximum permitted transverse distance of 15 millimeters.

BE2017 / 5051

With larger deflections it can happen that the transverse distance between the center posts at half height is greater than the maximum permitted transverse distance while the transverse distance between the center posts can decrease upwards and downwards below this maximum permitted cross distance, which inevitably occurs when closing the sliding door the sealing profiles collide with their lips against each other with possible damage as a result.

In addition, the sealing profiles do not hook together with their lips at half height, but next to each other, with the result that even with a closed door at half height there is an opening between the middle posts, along which rain and wind have free play.

At temperatures where the bending distance of the center profiles can make the transverse distance smaller than the required minimum transverse distance, when closing the sliding door it may happen that a sealing profile of the center pillar of one wing collides with the outer edge of the center pillar along the outer circumference of the other wing, as a result of which the sliding door can no longer be closed and serious damage may result.

The present invention aims to solve one or more of the above and other disadvantages.

To this end, the invention relates to a sliding door or sliding window with at least two wings which can slide relative to each other in the form of a frame with posts and rails in

BE2017 / 5051 in the form of profiles, in which the wings are slid in front and behind each other along two different parallel surfaces and in the closed position of the door the so-called center posts of both wings overlap with two sides facing each other, characterized in that these mutually facing sides of the center posts are provided with two guide pieces which together form a first guide, respectively a first guide piece on one of the center posts and a second guide piece cooperating therewith on the other center post, each of these guide pieces being provided with a tooth and groove with which they fit together in a closed state of the sliding door or sliding window in such a manner that they thereby hold the center posts with their facing sides at a nominal transverse distance from each other and wherein the edges have a wedge-shaped end with a beveled guide surface that one to d The groove-narrowing entry defines the fand of the other guide piece when, when the sliding door or sliding window is closed, the transverse distance between the center posts is greater than the nominal transverse distance.

For a nominal transverse distance of, for example, 12 millimeters and therefore a thickness of the guiding elements of approximately 12 millimeters, the edges of the guiding elements will still be able to intervene with each other when the sliding door is closed, to a maximum transverse distance of, for example, 21 millimeters to ensure sufficient conductivity between the to insure each other.

BE2017 / 5051

When closing the sliding door, the tines will come into contact with their chamfered sides before the sliding door reaches its closed position and when the sliding door is closed further, the tines will automatically guide in the transverse direction towards each other until in a situation where the door has reached its closed position in which the center posts overlap and the teeth engage in the grooves of the guide pieces, corresponding to a situation in which the transverse distance between the center posts approximately corresponds to the imposed nominal cross distance of, for example, 12 millimeters.

An advantage of such a first guide according to the invention is therefore that the transverse distance when closing the sliding door is automatically reduced to a transverse distance, whereby collisions between the lips of the sealing profiles are avoided before these lips engage one behind the other.

An associated advantage of the invention is therefore that the maximum permitted transverse distance between the center posts of, for example, 21 millimeters in the case of the invention is greater than the maximum allowed

25 transverse distance of, for example, 15 millimeter Bee a classic sliding door without first invention. conduction according to the Since the deflection is greatest is at half height from 30 the middle styles, enjoy it the preference the first

conducting conduction at this level.

BE2017 / 5051

The invention also relates to a second guide which can be used together with the first guide or alone.

This second guide is provided with a third guide piece on one of the two central posts, which is provided with a wedge-shaped end with a beveled guide surface facing away from the relevant central post, which slopes towards the outer edge of the wing concerned and which closes when the sliding door is closed. or sliding window forms a guide for the other center post to push the two center posts away from each other in the transverse direction when the cross distance between the center posts when closing is less than the imposed nominal cross distance.

This offers the advantage that when closing the sliding door, collisions can be avoided between a sealing profile on one center post with the other center post if the transverse distance would become smaller than the aforementioned minimum transverse distance between the profiles.

Thanks to the second guide, the center posts are pushed apart at a too small mutual transverse distance before a sealing profile threatens to collide with the center post of the other sealing profile.

An advantage is that this allows the center posts in the transverse direction to come much closer together, for example up to a transverse distance of 1 millimeter.

BE2017 / 5051 without risk of collision and the resulting damage or without the sliding door closing.

When using both guides together, much larger deflections inwards or outwards are permitted than in the case without, whereby the transverse distance between the center posts may vary between 1 and 21 millimeters for an imposed nominal transverse distance of 12 millimeters. with a much smaller permitted margin of 8 to 15 millimeters in the case without these guides for the same nominal transverse distance of 12 millimeters.

The invention also relates to a first or a second guide or a combination thereof for use in a sliding door or sliding window as described above.

Figure 12 shows in perspective a practical embodiment of the pieces of Figure 11 but in an assembled state for a lift sliding door;

figure 13 represents the view of figure 12 in a different situation.

Figure 1 shows, by way of example, a front view of a sliding door 1 in closed position.

BE2017 / 5051

The sliding door is composed of a fixed frame 2 for installation in a wall or the like and in this case two wings 3 slidably arranged therein with a frame composed of mainly the same profiles of aluminum or the like in the form of vertical posts 4 connected by horizontal rules.

The profiles are provided with a groove 6 which extends along the inner edge 7 of the wings 3 and in which a panel of glass or the like can be received.

The wings 3 are slid in two different parallel planes in front and behind each other in accordance with a sliding direction X-X ', wherein in the closed position of the sliding door 1 as shown in figure 1, the middle posts 4a and 4b, the so-called middle pillars 4, see each other overlapping frontally, one behind the other.

In this state, the center posts 4 are with two facing sides 8a and 8b opposite each other with a transverse distance A between both sides 8 measured in the transverse direction YY 'as shown in Figure 2 showing a nominal design situation with an imposed nominal transverse distance A of, for example, 12 mm.

Along the outer edge 9 of the wings 3, the center posts 4 are provided with a cover plate 10.

On the sides 8 facing each other, the central posts 4a and 4b are provided with a sealing profile 11 with a thickness

BE2017 / 5051

B which is smaller than the nominal transverse distance A and is, for example, equal to 8 mm for a nominal transverse distance of 12 mm.

The sealing profiles 11 are provided along the outside of a vertical edge 12 with a lip 13 which extends according to the abrasion direction XX 'in the direction of the sealing profile 11 on the other center post 4 and is spaced from the side 8 which is approximately equal depends on the thickness of the sealing profile 11.

The sealing profiles 11 are provided with a seal 14 on the aforementioned edge 12.

In the closed position of figure 2, the lips 13 engage one behind the other, thereby pressing the aforementioned seal 14 of the sealing profile 11 on the other center post 4 against the edge 12 to seal between the center posts 4a and 4b.

The sealing profiles 11 traditionally extend over the full height of the center posts.

In the case of the invention, the sealing profiles are

11 interrupted locally, for example in the middle, to make way for two guides 15 and 16 according to the invention, one above the other.

In case the conditions deviate from the nominal design conditions, for example with a larger or smaller temperature difference between inside and outside,

BE2017 / 5051 it happens that the transverse distance between the center posts 4 is greater or less than the nominal cross distance A, this due to the warping of the center posts 4 due to a differential expansion or contraction between inside and outside.

Figure 3 shows a situation in which the transverse distance has reached a minimum permitted value B, which is equal to the thickness B of the sealing profiles

11.

With an even smaller transverse distance it can indeed happen that the lips 13 when closing the sliding door 1 against the inner edge 7a and or 7b of the other center post

4a and / or 4b, as a result of which the door can no longer be fully closed or damage occurs. The risk points where a collision can occur are indicated with X in figure 3.

Figure 4 shows a situation in which a maximum permitted transverse distance C has been reached. Indeed, at an even greater distance than C, when closing the sliding door 1, the lips 13 will no longer hook behind or in each other, but next to each other, which would create an opening between the sealing profiles through which water and wind could penetrate.

The transverse distance is therefore limited to a range between B and C, for example between 8 and 15 mm.

BE2017 / 5051

According to the invention, use is made of the aforementioned guides in order to enable a longer range without the aforementioned risks.

Figures 5 to 7 relate to a first type of guide 15.

As schematically shown in perspective in Figure 6, this first guide 15 consists of a first guide piece 15a on the center post 4a and a second guide piece 15b cooperating therewith on the other center post 4b, each of these guide pieces 15a and 15b being provided with a tooth 17a 17b, respectively, and of a groove 18a, 18b, respectively.

The shape and dimensions of the tongue 17 and groove 18 are such that in the closed position of the sliding door 1 as shown in figure 5, the fands 17 and grooves 18 fit together in such a way that they thereby center stems 4a and 4b at a transverse distance corresponding to the aforementioned nominal transverse distance A.

The guide pieces preferably have a thickness D approximately equal to the nominal transverse distance A.

The flanges 17a and 17b end with a respective 19b narrowing entrance are provided with a wedge-shaped beveled guide surface 19a, which defines one towards the groove 18 for the tooth 17b, 17a, respectively, of the other guide piece

BE2017 / 5051 when closing the sliding door 1, the transverse distance between the center posts 4a and 4b is greater than the nominal transverse distance A.

This is for instance the case in figure 7 with a transverse distance D corresponding to a maximum transverse distance E which is still permissible to allow the teeth 17a and 17b to interlock with a sufficient overlap F to form a guide for the teeth 17 in the direction of the grooves 18.

Starting from the extreme situation of Figure 7, when the center posts 4a and 4b are slid further towards each other in the sliding direction XX ', the chamfered guide surfaces 19a and 19b slide over each other thereby forcing the center posts 4a and 4b together up to the nominal position of figure 5.

As can be clearly deduced from figure 7, the aforementioned maximum permitted transverse distance E, apart from the overlap F, is approximately twice the thickness D of the guide pieces 15a and 15b and thus approximately twice the nominal transverse distance A.

For a nominal transverse distance of, for example, 12 millimeters, the maximum permissible transverse distance, in the case of a first guide 15 according to the invention, may rise to, for example, 21 millimeters, this in comparison with the maximum permissible transverse distance of 15 millimeters without this first guide 15.

BE2017 / 5051

The guide 15 is designed such that when the center posts 4a and 4b move in the aforementioned manner towards each other when closing the sliding door, the lips 13 of the sealing profiles 11 interlock correctly as in the nominal situation of figure 2, without the lips 13 collide.

One or both guide elements 15 can be provided with a seal 20 which is in the closed position of figure

5 is pressed by the tooth 17 of the other guide piece 15 to form a seal between the two guide pieces 15a and 15b.

The guide pieces 15 are provided on their outer side with a recessed portion 21 which forms a seat for draft brushes 22 between the relevant guide piece 15 and the opposite central post 4.

The draft brushes 22 extend according to the longitudinal direction Z-Z 'of the center steels 4 and in line with the corresponding draft brushes 23 on the sealing profiles 11.

According to a practical and easy to realize embodiment, the guide pieces 15a and 15b are formed from a mainly plate-shaped elements of plastic with a thickness D that is substantially equal to the

nominal transverse distance A, where the plate-shaped guide pieces 15a and 15b with one side 26 on the to 30 sides facing each other 8 â j respectively 8b, of the

center posts 4a and 4b, respectively, are attached.

BE2017 / 5051

The groove 18 of the aforementioned guide element 15 of a central post 4 is formed in that the plate-shaped element along the side facing the relevant central post 4 is provided with a deepened part 25 with a depth Fa, respectively Fb, which is seen from a vertical side edge 26 of the plate-shaped element extends over a certain width Ga, respectively Gb, of the plate-shaped element.

The tooth 17 of the aforementioned guide element 15 is formed by the remaining thickness Ha, respectively Hb, of the plate-shaped element at the location of the groove 18 formed by the recessed portion 25.

Preferably, the thickness Ha and Hb of the tooth 17 and the depth Fa and Fb of the recessed portion 25 are approximately equal to half the thickness D of the plate-shaped element.

The aforementioned wedge-shaped end of the teeth 17 is formed by the teeth 17 over their full thickness Ha and Hb, respectively, to form the beveled guide surface 19.

The guide pieces 15a and 15b are positioned on the center posts 4a and 4b so that they are with the tip of the teeth 17a and 17b at a sufficient distance I from the inner edge 7 of the respective center post 4a or 4b to allow the guide between the guide pieces initiate the closing of the sliding door early enough to ensure that the lips of the

BE2017 / 5051

sealing profiles not during the closing movement. with colliding with each other come The second guide 16 is equipped with a third guide piece 16a on one from both middle styles, in this case on center post 4a.

This third guide piece 16a has a wedge-shaped end with a chamfered guide surface 27a that faces away from the center pillar 4a in question and that slopes towards the inner edge 7a of the center pillar. 4a and when closing the sliding door 1 forms a guide for the point X of the inner edge 7b of the other center post 4b as shown in figure 10, in order to push the two center posts away from each other in the transverse direction YY 'when the cross distance between the center posts 4 at closing is smaller than the nominal cross distance D and even smaller than the minimum required cross distance B to avoid a collision of a sealing profile 11 with a center post as shown in figure 3.

When the sliding door is closed, the second guide 16 will push the center posts 4a and 4b away from each other in a first phase to a transverse distance that is greater than the minimum transverse distance B before the situation of figure 3 is reached, whereby the sealing profile 11b extends beyond the inner edge 7a comes from the other center post 4a.

As shown in Figure 10, this allows the center posts 4a and 4b to cross in the transverse direction Y-Y '

BE2017 / 5051 very close to a still safe distance K of, for example, 1 millimeter to start the guidance in a safe way.

Thanks to the second guide 16, the minimum required transverse distance B of, for example, 8 millimeters without a second guide 16 is greatly reduced to a distance K of, for example, 1 millimeter.

The chamfered guiding surface 27a of the third guiding piece 16a on the center post 4a is, viewed in the sliding direction, situated between the guiding surface 19a of the first guiding piece 15a on the respective center post 4a and the birch edge 7a of this center post 4a and at a distance J from this birch edge 7a .

As a result, the transverse distance between the middle posts 4a and 4b is first increased to the thickness of the third guide element 16a, which is preferably equal to the thickness D of the guide elements 15a and 15b of the first guide and thus approximately equal to the nominal transverse distance A, so that , after reaching this transverse distance D, hook the teeth 17 of the first guide as in the nominal situation of figure 5.

Preferably, a fourth guide piece 16b having a chamfered guide surface 27b complementary to the chamfered guide surface 27a of the third guide piece 16a is provided opposite the third guide piece 16a on the opposing center post 4b.

BE2017 / 5051

According to a practical embodiment, the third and fourth guide piece 16a and 16b are also made of plastic as a plate-shaped element with a thickness D, wherein the aforementioned beveled guide surfaces 27a and

27b are formed by chamfering a vertical edge

28a and 28b, respectively, of the plate-shaped element over the full thickness D of this element.

Each guide piece 16a and 16b is provided with a recessed portion 29 for the draft brushes.

At least one of the two beveled guide surfaces 27a and / or 27b is provided with a seal 30 which, in the closed position of the sliding door 1, is pressed between these two guide surfaces 27a and 27b to form a seal between the two guide surfaces 27a and 27b.

According to a preferred aspect of the invention, the guide pieces are composed in one piece on the same center post 4 as in figure 11, in which for example the first and third guide piece 15a and 16a and the second and fourth guide piece 15b and 16b in the vertical direction YY 'one above the other are connected to one whole.

In this configuration, the geometric planes of the chamfered guide surfaces 27a and 27b of the third and fourth guide piece 16a and 16b pass through the tip of the wedge-shaped portion of the first or second guide piece

15a and 15b so that the edges 26 and the edges 28 are included

BE2017 / 5051 Extend each other in accordance with the longitudinal direction 2Z 'of the posts 4.

This improves the compactness of the guides 15 and 16.

Figure 12 shows how these composite guides are mounted, omitting the front center post 4a for clarity.

For example, the assembled parts are attached to the center posts by screws 31 or the like.

The example shown in Figure 12 shows a situation of a lift-sliding door in which one wing 3 must first be lifted relative to the other wing in order to unlock the sliding door 1 before the wings 3 can be slid apart to open the sliding door 1 .

In this case, in the locked closed position of Figure 12, a certain vertical clearance L must be left between the guide pieces to allow mutual vertical displacement between the guides when unlocking the lift sliding door as illustrated with reference to Figure 13 in which of Figure 12, the left wing is pushed up relative to the right wing as shown by arrows M.

BE2017 / 5051

In the case of a sliding door without lift release, the play L is not necessary, but a small play is desirable for safety reasons that the guides do not collide when closing the sliding door 1.

The height of the guide pieces does not have to be large, for example in the order of a few centimeters.

It is clear that the guide pieces 15a, 15b of the first guide 15 and the guide pieces 16a and 16b of the second guide can be interchanged.

It is clear that the dimensions described above were only indicative as a prelude to tolerate their interrelationships.

Strictly senso the first and second guides 15 and 16 need not be present together and can also be used separately in a sliding door according to the invention, for example in areas where the deflection of the center posts can always be expected to take place outwards or always inwards , then using either the first or the second guide 15 or 16.

In areas where deflection can occur in both directions, it is preferable to use a combination of first and second guides 15 and 16.

BE2017 / 5051

The present invention is by no means limited to the exemplary embodiments described in the figures, but a sliding door or sliding window according to the invention and guides used therewith can be realized in various shapes and sizes without departing from the scope of the invention.
