Description

[0001] The invention relates to an alignment fitting for aligning a door leaf, a door leaf with such an alignment fitting, and also a method for assembling an alignment fitting.

[0002] Alignment fittings for aligning a door leaf are known, e.g. ITMI982587A1, ITMI20060337U1, EP3406824A1, US29536314A, US2706543A and ITMI20070305U1.

[0003] In contrast, the present invention aims to provide an alternative alignment fitting as well as a method for assembling such an alignment fitting that is as simple as possible.

[0004] This problem is solved according to the invention by an alignment fitting with the features of claim 1. Functionally important are two different thread pitches: one for the internal thread of the screw channels, the first external thread of the rod and the external thread of the screw-in sleeve, and the other for the second external thread of the rod and the internal thread of the screw-in sleeve.

[0005] The alignment fitting according to the invention has in particular the following advantages: Suitable for both professional and industrial use. Can be used with hinged and sliding doors (front-facing), especially for mounting in the front-facing handle profiles of sliding doors. Suitable for door thicknesses from 16 mm to 26 mm. Easy installation in an aluminum handle profile. Can be used with doors of varying heights. No fixed lengths of the alignment fitting and handle profiles are required. Easy to understand and use. Aligns door warping in both directions. The alignment fitting can be operated from above. Doors can be aligned when closed. Retrofittable and cost-effective.

[0006] Preferably, the internal thread of the screw channels, the first external thread of the rod, and the external thread of the screw-in sleeve are each a first metric thread, and the second external thread of the rod and the internal thread of the screw-in sleeve are each a second metric thread that is smaller than the first metric thread. Alternatively, two fine threads or a combination of one metric and one fine thread can be used.

[0007] Preferably, the thinner rod end and a middle rod section located between the two rod ends each have an outer diameter that is smaller than the inner diameter of the screw channels. More preferably, the inner channel between the two screw channels has a middle channel section with an incircle whose inner diameter is larger than the outer diameters of the thinner rod end and the middle rod section.

[0008] The hollow profile is preferably made of metal, in particular an aluminum extrusion profile, and can have a rectangular, in particular square, outer cross-section.

[0009] The rod can be a single piece or, preferably, formed by a threaded rod, one end of which forms the thinner end, and a threaded sleeve screwed onto the other end of the threaded rod, forming the thicker end and being permanently and non-removably connected to the threaded rod. Advantageously, the threaded sleeve can incorporate a handle for turning, e.g., in the form of a polygon. Furthermore, it is advantageous for the threaded rod to be composed of several manageable (e.g., 1 m long) threaded rod sections, which correspondingly reduces the packaging size for the components of the erection fitting.

[0010] The hollow profile is particularly advantageous when integrated into a handle profile for the door leaf, i.e., molded onto it as a single piece.

[0011] In the assembled erection fitting, the rod is screwed with its thicker end into one of the two screw channels and with its thinner end into the screw-in sleeve screwed into the other, second screw channel and can be rotated by means of the rotary handle in order to generate either a compressive or a tensile stress in the rod and thus in the hollow profile due to the different thread pitches, depending on the direction of rotation of the rotary handle.

[0012] The invention also relates to a door leaf, in particular a sliding or revolving door, with an alignment fitting mounted on the door leaf in the longitudinal direction of the door, designed as above, in order to produce a transverse deformation of the door leaf perpendicular to the front and back of the door in one direction or the other, depending on the direction of rotation of the rotary handle, and to counteract a front or back bulging of the door leaf.

[0013] The hollow profile can be mounted, for example, on a narrow side of the door leaf or in a longitudinal groove on the front or back of the door.

[0014] Finally, the invention also relates to a method for assembling an alignment fitting designed as above, using the method steps of claim 13.

[0015] Preferably, the screw-in sleeve is screwed into the second screw channel until it rests against the outside of the hollow profile with a collar.

[0016] If necessary, an internal thread can be cut into each of the two ends of the inner channel, in particular by means of a self-tapping screw, in order to form the screw channels.

[0017] Further advantages of the invention will become apparent from the description, the claims, and the drawing. The embodiments shown and described are not to be understood as an exhaustive list, but rather serve as examples for illustrating the invention.

[0018] They show: Fig. 1 the essential components of an alignment fitting according to the invention; Fig. 2 a modification of one in Fig. 1 rod shown; Figs. 3a-3c, 4a-4c, 5a-5c the individual process steps for assembling the components of the alignment fitting according to the invention; Figs. 6a-6c the alignment of a door leaf using the alignment fitting according to the invention; Fig. 7 another embodiment of a Fig. 1 shown hollow profile; and Figs. 8a-8c the alignment of a door leaf with the in Fig. 7 shown hollow profile by means of the alignment fitting according to the invention.

[0019] The in Fig. 1 shown alignment fitting 1 used to align a door leaf 2 ( Fig. 6a ), here a sliding door, and has the following components: a hollow profile to be attached to the front of the door leaf 2 3 made of metal, e.g. aluminum, here integrated into a handle strip 4 featuring a handle profile with an inner channel 5, whose two canal ends 5a, 5b ( Fign. 5b, 5c ) are open at the ends and each has a screw channel 6a, 6b with the same internal thread 7, here, have M8 internal threads; a rod 8 with two rod ends of different thicknesses 8a, 8b, wherein the thicker rod end 8a has a first external thread corresponding to the internal thread 7 of the screw channels 6a, 6b 9, Here, an M8 external thread, and the thinner rod end 8b a second external thread that is different from the first external thread 9 and smaller in diameter. 10, here M5 external thread, and wherein the thicker rod end 8a has a front-facing rotary handle. 11 features; and a sleeve-shaped screw-in sleeve open on both sides 12 with an external thread corresponding to the internal thread 7 of the screw channels 6a, 6b 13, Here, an M8 external thread is used, and an internal thread corresponding to the second external thread 10 of the rod 8. 14, Here, M5 internal thread.

[0020] The middle section of the rod 8c The rod ends 8a and 8b also have an external thread corresponding to the second external thread 10. 15,Here, an M5 external thread is present, but it can alternatively be unthreaded. In any case, the thinner rod end 8b and the middle rod section 8c each have an outer diameter that is smaller than the inner diameter of the screw channels 6a, 6b. Between the two end screw channels 6a, 6b, the inner channel 5 has, for example, an unthreaded middle section. 5c ( Fign. 5b, 5c ) with an incircle whose inner diameter is larger than the outer diameters of the thinner rod end 8b and the middle rod section 8c, and may be smaller than the inner diameter of the screw channels 6a, 6b. The hollow profile 3 can, for example, have a rectangular, in particular square, outer profile cross-section.

[0021] The rod 8 can be one piece or, as in Fig. 2 shown, two-part, connected by a threaded rod 16,one end of which forms the thinner rod end 8b, and is screwed onto the other end of the threaded rod 16 by a threaded sleeve open on one side 17, which is connected to the threaded rod 16 in a rotationally fixed and non-removable manner. The threaded sleeve 17 forms the thicker rod end 8a with the M8 external thread 9 and the M5 internal thread 14. At the closed end of the sleeve, the threaded sleeve 17 has the turning handle 11 in the form of an internal polygon (e.g., a 4 mm hex socket). The threaded rod 16 can itself be composed of several threaded rod sections, in particular screwed together.

[0022] The following describes the individual assembly steps for retrofitting the alignment fitting 1 to a handle strip 4 - which is already mounted on the door leaf 2.

[0023] If necessary, the rod 8 is cut to a predetermined length, e.g. to the length of the hollow profile 3 minus 25 mm.

[0024] If necessary, a cutting screw is used first. 18, e.g. M8x40 self-tapping screw, the M8 internal thread 7 of the two screw channels 6a, 6b is cut into the inner channel 5 at each end ( Fign. 3a-3c ).

[0025] Then the rod 8, with the thinner rod end 8b leading, is inserted through the first screw channel 6a into the inner channel 5 ( Fig. 4a ) and, by using a tool (e.g. a 4mm hex key) to engage the rod 8 with the rotary handle 11 19 As the rod is rotated, the thicker rod end 8a is screwed into the first screw channel 6a to a certain extent, e.g. approx. 20 to 25mm ( Fign. 4b, 4c ).

[0026] A cylinder head screw (e.g. M5x12mm) 20 is screwed into the M5 internal thread 14 of the screw-in sleeve 12 until it abuts the screw-in sleeve 12, in order to form a first screw connection effective in the screw-in direction 21 together with the screw-in sleeve 12 22 to train ( Fig. 5a ).

[0027] Subsequently, by turning the cylinder head screw 20 using a tool (e.g., a 4 mm hex key) 19, the screw-in sleeve 12 is screwed into the second screw channel 6b on one side and onto the thinner rod end 8b on the other, until the cylinder head screw 20 rests against the rod 8 and the first screw connection 22 together with the rod 8 forms a second screw connection effective in the screw-in direction 21. 23 forms. The cylinder head screw 20 forms a stop in the screw-in sleeve 12, which limits the screwing of the screw-in sleeve 12 onto the thinner rod end 8b, for example to about half of the maximum possible screwing length.

[0028] By turning the cylinder head screw 20 further, the screw-in sleeve 12 is advanced further into the second screw channel 6b until its collar contacts the end face. 24screwed into the outside of the hollow profile 3 and, on the other hand, the rod 8 is rotated, whereby the thicker rod end 8a is screwed into the first screw channel 6a until it reaches an axial zero position ( Fig. 5b ).

[0029] Finally, the cylinder head screw 20 is unscrewed from the screw-in sleeve 12 ( Fig. 5c ), in order to remove the stop and thus be able to screw the thinner rod end 8b further into the screw-in sleeve 12. From the zero position, the rod 8 can therefore be rotated in both directions.

[0030] As a result, the rod 8 is screwed into the first screw channel 6a with its thicker rod end 8a and into the screw-in sleeve 12 screwed into the second screw channel 6b with its thinner rod end 8b and can be rotated by means of the rotary handle 11.

[0031] Fig. 6a This is shown by means of a lateral profile leg 25A handle profile with handle 4 and hollow profile 3, in which the alignment fitting 1 is mounted, is screwed to one narrow side of the sliding door 2 along the length of the door. The rotary handle 11 is located on the top of the sliding door 2. The rod 8 can be rotated using a tool 19 (e.g., a 4 mm Allen key) that engages the rotary handle 11. Due to the different M8 and M5 thread pitches at the thicker and thinner ends 8a, 8b of the rod, the rotation of the rod 8 results in a change depending on the direction of rotation. 26a, 26b This creates either a compressive or a tensile stress in the rod 8 and thus in the hollow profile 3. Depending on the direction of rotation 26a, 26b, this results in a force acting towards the front and back of the door. 2a, 2b right-angled transverse deformation of the door leaf 2 in one or the other transverse direction 27a, 27b, resulting in a frontal or rearward bulge 28a, 28b counteracting the sliding door 2 so that the sliding door 2 can be aligned ( Fign. 6b, 6c ).

[0032] From the hollow profile 3 of the Fign. 1-6 This differs in Fig. 7 The hollow profile 3 shown is distinguished only by two lateral profile legs 25 present on both sides and by the absence of a handle strip.

[0033] Fig. 8a This shows a longitudinal groove 29 the sliding door 2 inserted and screwed to the back of the door 26 by means of the two side profile legs 25 hollow profile 3 of the Fig. 7 , in which the alignment fitting 1 is mounted. Depending on the direction of rotation 26a, 26b of the rotary handle 11, a front or rear bulging 28a, 28b of the sliding door 2 can be counteracted and thus the sliding door 2 can be aligned.
