Description

[0001] The invention relates to assembly devices for railings with a straight guide, wherein holding devices for the upper and lower chord of the railing are arranged on the guiding component and at least one holding device for an element in the form of the post and infill elements of the railing is arranged on at least one guided component of the straight guide.

[0002] German patent application DE 90 15 425 U1 discloses a welding device or jig that is particularly suitable for the production of railings and grilles. It allows for simple and highly precise adjustment of the mutual spacing of support or holding elements. This ensures that all support or holding elements maintain the same mutual spacing. Scissor elements with scissor links are used for this purpose.

[0003] The infill elements are inserted at equal intervals using the device or jig. The spacing is adjusted from element to element, meaning that, due to tolerances, a perfectly uniform spacing cannot be guaranteed, especially towards the end. Furthermore, infill elements of varying widths cannot be easily integrated into the railing.

[0004] The publication DE 20 2006 005 926 U1 describes a railing welding jig, in which a frame consisting of two longitudinal tubes and two transverse tubes is connected at the corners by hinges and attached to a support via a two-axis joint. This allows for easy adjustment of the angle of inclination. The railing can also be tilted for installation. The infill panels are positioned using sliding blocks. No scale for positioning the infill panels is provided.

[0005] German patent application DE 100 11 089 A1 discloses a device for positioning multiple bars in which the spacing between the bars can be adjusted both collectively and individually. Additionally, the angular positions of the bars can also be varied continuously, collectively and / or individually. Movable units are used for the individual bars to be positioned. The displacement devices used for this purpose can be manually operated, so that spacing deviations can be corrected.

[0006] German patent application DE 42 21 469 A1 discloses a grating and a method for manufacturing gratings. The grating length and width, as well as the spacing of the bearing and crossbars, are entered into a computer. The computer determines their number based on a central longitudinal axis and a central transverse axis on both sides, maintaining a constant spacing. Since the tolerances in positioning the bearing and crossbars do not accumulate, dimensionally accurate gratings are produced that can be easily joined together, resulting in a symmetrical installation pattern.

[0007] The invention specified in claim 1 is based on the objective of making it easy to assemble a railing.

[0008] This problem is solved by the features listed in claim 1.

[0009] The mounting devices for railings with a straight guide, wherein holding devices for the upper and lower chord of the railing are arranged on the guiding component and at least one holding device for an element in the form of the post and infill elements of the railing is arranged on at least one guided component of the straight guide, are characterized in particular by the simple possibility of mounting the railings.

[0010] The guiding component is at least a guide rail, and the guided component is at least a carriage on the guide rail. The guided component is a guided part of the linear guide equipped with a displacement measuring system. The displacement measuring system has at least one optoelectronic displacement sensor.Furthermore, the displacement measuring system is interconnected with a control unit in such a way that the control unit is a control unit which, by means of the displacement measuring system and a drive connected to the control unit, moves the guided component to the respective position and summes the distance between positions of elements one after the other, wherein the control unit is a control unit which determines the number of elements from the minimum distance of the elements taking into account the respective width and from this either sets the positions of the elements equal to the minimum distance if the number is a whole number or rounds the number up to the next whole number if the number is not a whole number and from this determines the new distance.

[0011] A railing essentially consists of a top rail, a bottom rail, posts, and infill panels. The latter can also be designed as decorative elements. The panels between the posts must maintain a certain minimum distance. To ensure a largely uniform distribution of the panels, the dimensions of the panels themselves, any tolerances, and dimensional deviations must be taken into account. Otherwise, dimensional deviations can occur, particularly at the end of a chain of panels, resulting in a very small gap between the last panel and the end post in order to maintain the minimum distance. This compromises the overall aesthetic appeal of the railing.

[0012] The linear encoder and the summing control unit advantageously make it easy to create railings with equal spacing between elements. The positions of the elements are predetermined. Summing the distances ensures consistent spacing between the elements.

[0013] The guided component is a guided element of the linear guide, equipped with a drive and a position measuring system. Furthermore, the drive and the position measuring system are interconnected with the control unit in such a way that the control unit determines the number of elements based on the minimum spacing of the elements, taking into account their respective widths. From this, the control unit either sets the positions of the elements to the minimum spacing if the number is a whole number, or rounds up to the nearest whole number if the number is not a whole number, and then determines the new spacing. This ensures a uniform spacing between the elements of the railing. At the same time, elements of different widths can also be integrated into the railing without any discrepancies in spacing. These latter elements are particularly suitable for decorative elements, which may also have varying widths within the railing.

[0014] Advantageously, elements of different widths can also be used to create a railing with equal spacing between them. This applies particularly to decorative elements or intermediate posts.

[0015] Advantageously, the guided component is also coupled to a drive, allowing it to be moved by a motor. The drive is, for example, an electric motor with a gearbox, which is advantageously self-locking or self-locking. With the latter, the guided component is fixed in place when the electric motor is not engaged.

[0016] Advantageous embodiments of the invention are specified in claims 2 to 6.

[0017] According to the further development of claim 2, the leading component and the guided component are advantageously coupled to each other and to the drive via a threaded spindle-threaded nut system, a gear-rack system or a traction device.

[0018] According to the further development of claim 3, the holding devices each consist of two holding elements for the upper and lower chords that are guided and movable relative to each other and can be locked in specific positions. This allows railings of different heights to be easily constructed using the mounting device.

[0019] According to the further development of claim 4, the holding device is connected to the guided component via a lockable swivel joint, so that an element can be rotated in the plane of the upper and lower chords, and thus the angle relative to the upper and lower chords can be adjusted. Railings adapted to the stairs can be easily manufactured using the assembly device.

[0020] According to the further development of claim 5, the leading component is rotatably connected to stands via lockable joints. This allows the railing to be easily fixed in simple working positions during assembly.

[0021] According to the further development of claim 6-7, the displacement measuring system is interconnected with the control unit in such a way that the value zero can be assigned to at least one position of an element. This is particularly advantageous for intermediate posts, ensuring equal spacing of the elements in the individual sections. Advantageously, elements with different designs can also be integrated into the railing while maintaining equal spacing.

[0022] An embodiment of the invention is shown in principle in the drawing and is described in more detail below.

[0023] It shows the Fig. a mounting device for railings.

[0024] A mounting device for railings essentially consists of a linear guide 1 with a guiding component, a guided component, holding devices 2 for the upper and lower chord of the railing, a holding device 3 for an element, at least one displacement measuring system, a drive and a control device.

[0025] The figure shows a mounting device for railings in a basic representation.

[0026] The linear guide 1 consists of a guide rail 4 as the guiding component and a slide 5 on the guide rail as the guided component. The guide is based on a known sliding or rolling element guide.

[0027] The carriage 5 is located between two beams 6 spaced apart from each other, one of these beams 6 supporting the guide rail 5 and thus forming the guiding component of the linear guide 1.

[0028] On the beams 6 are mounting devices 2 for the upper and lower rails of the railing. Each mounting device 2 consists of two mounting elements 7 that are guided and movable relative to each other and can be locked in specific positions. This allows railings of varying heights to be easily constructed. As is known, a mounting element 7 consists of a column 8 and a U-shaped receptacle 9 rotatably mounted on it. Using these mounting devices 2, the upper and lower rails can be positioned at a distance from each other.

[0029] The holding device 3 for an element in the form of the railing posts and infill panels is arranged on the carriage 5. The infill panels also serve as decorative elements. The holding device 3 is connected to the carriage 5 via a lockable swivel joint, allowing the element to rotate in the plane of the top and bottom rails and thus enabling adjustment of the angle relative to the top and bottom rails.

[0030] The carriage 5 is a guided component of the linear guide 1, equipped with a displacement measuring system. The displacement measuring system has at least one optoelectronic displacement sensor. Digital displacement measurement signals are obtained in an optical beam path by using a scale system with incremental transparent grids in conjunction with a counting and evaluation unit. The measured displacement is a multiple of the scale division.

[0031] The distance measuring system is interconnected with the control unit and the drive in such a way that predetermined positions of elements are approached one after the other and the distance between positions of the elements is summed up.

[0032] Advantageously, a post representing one of the positions, or the zero position, serves as the reference point. The displacement measuring system is interconnected with the control unit in such a way that the value zero can be assigned to at least one position of an element. Summing the measurements ensures that, provided the minimum spacing is maintained, any existing or occurring tolerances do not lead to an uneven distribution of the elements at the end of the railing.

[0033] The drive is an electric motor with a gearbox and a gear that engages with a rack on the leading component. The drive is connected to the slide 5. The gearbox advantageously has a self-locking or self-locking mechanism. The latter is implemented, for example, via a worm gear. In the uncontrolled operation of the drive, this ensures that the slide 5 is fixed in the predetermined position of the element.

[0034] The beams 6 are rotatably connected to stands 11 via lockable joints 10.

[0035] In one embodiment, the drive and the position measuring system are interconnected with the control unit in such a way that the control unit determines the number of elements from the minimum distance of the elements, taking into account the respective width, and from this determines the positions of the elements, either equating the minimum distance if the number is whole or rounding up the number to the next whole number if the number is not whole, and from this determining the new distance.
