DETAILED DESCRIPTION OF THE INVENTION

(10) The sliding window 1 shown in FIG. 1 comprises a frame 2, a fixed leaf 3 and a slidable leaf 4.

(11) In order to be able to move the slidable leaf 4, in this example but not necessarily, a motor 5 is provided that is connected to the slidable leaf 4 via a drive belt 7 running over a reversing roller 6 and a first carriage 8, not shown in FIG. 1.

(12) A lock 9 is also provided, which together with a lock plate 10 provided on the first carriage 8, can lock the slidable leaf 4 in a closed position.

(13) The motor 5, reversing roller 6, lock 9 and drive belt 7 are schematically indicated in FIG. 1, although they are affixed in the frame 2 and are thereby enclosed and thus not visible from the outside.

(14) As can be seen in FIGS. 2 to 5 the slidable leaf 4 essentially consists of a glass panel 11 that is provided on its sides and top with a side profile 12 or a top profile 13.

(15) In this example but not necessarily, these side and top profiles 12, 13 have an identical cross-section. They are provided with a groove 14 with undercut flanks 15 oriented towards the outside, thus away from the glass panel 11.

(16) The aforementioned first carriage 8 is mounted in the groove 14 of the top profile 13. A coupling 18 is mounted on this first carriage 8 for the said drive belt 7, as well as a lock plate 10 for the lock 9. The drive belt 7 is normally connected to the coupling 18 in the situation shown, but for the purpose of a better presentation of the invention it is not shown in FIGS. 2 to 9.

(17) As is especially clear from FIG. 5, the shape of the bottom part of the first carriage 8 is largely complementary to the shape of the groove 14 of the top profile 13.

(18) The first carriage is provided with a horizontal hole 19 with an internal screw thread.

(19) A second carriage 20 is affixed in the groove 14 of the side profile 12, which is located close to the top of this side profile 12.

(20) A horizontal passage 21 is made in this second carriage 20.

(21) The first carriage 8 and the second carriage 20 are coupled together by means of an adjusting rod 22 and a first nut 23.

(22) The adjusting rod 22 is provided over its entire length with an external screw thread that is complementary to the screw thread in the hole 19 of the first carriage 8. The adjusting rod 22 has a head 24 that is provided with a hexagonal recess 25 for a socket screw key.

(23) At some distance from the head 24 there is a thickening, in this case in the form of a second nut 26 that is affixed to the adjusting rod 22 by means of the screw thread, and is fastened thereto, for example by welding or gluing.

(24) The end of the adjusting rod 22 turned away from the head 24 is screwed in the hole 19 of the first carriage 8. The other end, i.e. the end with the head 24, is inserted through the passage 21. By means of a first nut 23 the adjusting rod 22 is fastened to the second carriage 20, whereby the second carriage 20 is fastened between the first nut 23 and the second nut 26, so that the adjusting rod 22, and thus also the first carriage 8, is firmly secured.

(25) The second carriage 20, and in particular the top end thereof, thereby forms, via the adjusting rod 22, a gripping element 20a that is unmovable in the horizontal direction for the first carriage 8 and the components fastened thereon, that restrains this first carriage 8 thereof from moving horizontally.

(26) In order to adjust the position of the lock plate 10 in the longitudinal direction of the top profile 13, indicated by arrow P in FIG. 3, the first nut 23 is loosened somewhat, after which the adjusting rod 22 can be rotated from the side of the side profile 12 by means of a socket screw key that is inserted in the head 24 of the adjusting rod 22.

(27) This results in the adjusting rod 22 being turned in or out of the hole 19 in the first carriage 8, so that the distance between the second carriage 20 and the first carriage 8 becomes smaller or larger. As soon as the first carriage 8 is in a position in which the lock plate 10 correctly engages with the lock 9, the first nut 23 is tightened again.

(28) The first carriage 8, the adjusting rod 22 and the second carriage 20 together form an adjustment mechanism in order to adjust the position of the lock plate 10 and to be able to fasten the lock plate 10 to the leaf 4.

(29) This action can be done while the leaf 4 is mounted in the frame 2, because for the adjustment only access to the first nut 23 and the head 24 of the adjusting rod 22 is required, whereby this access is possible from the side of the side profile 12.

(30) The alternative embodiment of a slidable leaf 4 shown in FIGS. 6 to 9 differs from the embodiment described above by the adjustment mechanism being constructed differently with regard to the following points: Instead of one adjusting rod 22, there are two adjusting rods 22A, 22B, each with a head 24A, 24B with a recess 25 for a socket screw key, but without the aforementioned thickening. In this embodiment, the head 24A, 24B of the two adjusting rods 22A, 22B is indeed thickened. Two holes 19A, 19B with a screw thread are also made in the first carriage 8, and two passages 21A, 21B in the second carriage 20, whereby the heads 24A, 24B of the adjusting rods 22A, 22B do not fit through the passages 21A, 21B. A first adjusting rod 22A is not inserted through a passage 21A in the second carriage 20, but is affixed such that the head 24A is at the location of a passage 21A such that it can be operated with a socket screw key via the passage 21A of the head 24A. The second adjusting rod 22B is inserted through a passage 21B in the second carriage 20.

(31) The adjustable securing of the lock plate 10 can be done in this embodiment by further turning the two adjusting rods 22A, 22B in or out of the holes 19A, 19B in the first carriage 8 by means of a socket screw key. Hereby the second carriage 20 acts as an end stop for the heads 24A, 24B of the adjusting rods 22A, 22B.

(32) If the lock plate 10 has to be adjusted in a direction towards the side profile 12, the first adjusting rod 22A is first turned further in a hole 19A, to enable the first carriage 8 to be pulled in the direction of the second carriage 20, after which the second adjusting rod 22B is turned further into a hole 19B to effectively pull the first carriage 8 to the second carriage 20 and to secure the first carriage 8.

(33) If the lock plate 10 has to be adjusted in a direction away from the side profile 12, the second adjusting rod 228 is turned further out of a hole 19B to enable the first carriage 8 to be pushed away from the second carriage 20, after which the first adjusting rod 22A is turned out of its hole 19A to effectively push the first carriage 8 away from the second carriage 20 and to secure the first carriage 8.

(34) Although in the above example a motor 5 to drive the leaf 4 and a coupling 18 of a drive belt 7 with the leaf 4 are described, the invention is not limited to sliding windows 1 with a drive motor and leaves 4 for this purpose.

(35) Although in the above examples the lock plate 10 is described as a separate component screwed to the first carriage 8, the lock plate 10 together with the first carriage 8 can also form one component, for example as a lock plate 10 with a base that is complementary to the shape of the groove 14.

(36) The present invention is by no means limited to the embodiments described as an example and shown in the drawings, but a sliding window or sliding door according to the invention can be realised in all kinds of forms and dimensions and according to all kinds of variant methods, without departing from the scope of the invention.
