Particularly advantageous screws with a conical screw head, which is in particular provided with an inner octagon. Depending on the design of the drilled holes in the guide profiles, which are based on the later However, other screws can be used. In addition to the screws, additional dowels may be used depending on the nature of the mounting surface. The rail system may preferably include additional auxiliary elements, such as metal brackets, support columns or other fasteners, to flexibly attach the lifting system to, for example, a drywall.

The drill rails on the two side surfaces of the guide profiles are preferably designed such that a distance between two holes of each drill bar and / or between the ends of the guide profile and the adjacent holes each drill bar is the same. Under one end of the guide profile can be understood an end face of the guide profile. The distance between two bores or the ends of the guide profile and adjacent bores is preferably equal or normalized.

The holes of each drill bar are preferably all the same shape and adapted to the size and shape of the mounting means, in particular the screws. Advantageously, each bore has a recess for receiving, in particular for completely receiving, a screw head of the screws used on one of the lateral surface opposite this bore. This allows a low-friction guidance of the carriage along the inner sides of the guide profiles are made possible. When using a conical screw head, the bores of each drill string are correspondingly conically shaped, with the cross section of each bore decreasing from the inside of the associated side surface towards the side surface of the guide profile. Alternatively, when using a disc-shaped or hemispherical screw head, a cylindrical or correspondingly complementary recess in the dimension of the screw head can be provided.

The rail system according to the invention may advantageously contain at least one cross bracing for stabilization. The cross brace may be arranged to interconnect the two guide rails. Advantageously, the transverse strut can be arranged in the region of the ends of the guide profiles, wherein an arrangement at the upper ends of the guide profiles is further preferred. It is also conceivable, however, an arrangement of multiple cross braces, which are distributed over the length of the guide profiles. Preferably, the guide profiles can be aligned perpendicular to the cross braces. The present invention further relates to a carriage for a multifunctional lifting system with a rail system, wherein the rail system may be in particular the rail system described above. Invention According to the carriage contains a support unit, a fixing device for working and / or functional units, at least one suspension and two rolling rails. Each of the two rolling rails has at least one arranged on a longitudinal side of the rolling track roller. The rolling rails are aligned parallel to each other, attached to the side of the support unit, so that the rollers along the rail system are feasible.

Instead of just one roller, each rolling track may have a plurality of rollers, in particular so many that the carriage rests on several sides of a guide rail with at least one roller, for example on each inside of a cross-sectionally U-shaped guide profile, as described above, the inner sides of those pages are that limit the space enclosed by the profile. Preferably, two rollers may be provided for each side of a guide profile.

The rollers of the rolling strips are preferably arranged so that they are in contact with the inner sides opposite the elongated side surfaces of the guide profiles. The rollers thus allow a low-friction running of the carriage along the rail system. The rolling rails can advantageously be formed of metal, solid metal blocks, such as aluminum blocks, or metallic frame structures are preferred because they increase the stability of the carriage. The rollers may be formed, for example, as metal wheels or plastic wheels. The rolling rails are firmly but also releasably connected to the support unit, in particular a screw, welding, soldering or locking is conceivable. Each rolling strip may have at least three or a multiple of three rollers, wherein at least two rollers are aligned with their axes of rotation perpendicular to each other. The axes of rotation can also be arranged perpendicular to a longitudinal direction or a vertical direction of the rolling rails. In particular, the three rollers may contact different elongated side surfaces of the associated guide rail system profiles to allow optimum guidance with minimal friction. For this purpose, advantageously two rollers arranged in parallel with their axes of rotation are offset relative to one another in such a way that they protrude over different side edges of the longitudinal side of the rolling strip carrying the rollers and thus contact the two legs of the outer side surfaces of the guide profiles. The third roller is preferably arranged with its axis of rotation perpendicular to the other two rollers and contacts the web of the central side surface of the guide profile, which connects the two outer side surfaces together.

In order to make the carriage for a lifting system so stable that loads of up to 1000 kg, in particular up to 500 kg, especially 300 kg, are portable, the support unit of the carriage advantageously as a metal plate, in particular as a frame construction with a multiple, especially quadruple folded metal plate, be formed. The multiply folded metal plate is advantageously adapted to the rolling rails. Thus, a metal plate having two first folds parallel to a longitudinal direction of the support unit, whose distance corresponds to a long edge of the rollers having the side of the rolling bar. The metal plate may further comprise two second folds, each arranged parallel to and spaced from the first folds, wherein a distance between each first fold and the adjacent second fold of the short edge length of the rollers having the side of the rolling bar corresponds, so that the Metal plate in the folded state surrounds the cuboid rolling rails. The quadruple-folded metal plate thus encloses the rolling rails on their sides aligned perpendicular to the rollers and has been connected to the rolling rails, in particular riveted, screwed, soldered or welded, in order to form the carrying unit.

Alternatively, the carrying unit of the carriage may be formed as a solid plate or in the form of a skeleton of metal or plastic. The skeleton can be a series of struts that align the rolling rails parallel to each other. Suitable metals are in particular aluminum or stainless steel alloys. There is also the possibility that the carrying unit is formed integrally with the rolling rails, in particular as cast aluminum or even fiber-reinforced plastics.

AUSFUEHRUNGSBEISPIELE

FIG. 1A shows a perspective view of a guide profile 1 of a rail system according to the invention. The guide profile 1 has two outer elongated side surfaces 10 and a central side surface 12, wherein the central side surface 12 is aligned transversely, in particular perpendicular to the outer side surfaces 10, 11 and these together. In other words, the guide profile 1 has a U-shaped cross section, which can also be seen in FIG. 1B. On one of the outer side surfaces 10 and on the middle side surface 12, a respective drill bar 13 is formed, which contains a plurality of bores 130. A distance A between each adjacent borehole 130 is normalized to a certain value. In addition, the distance B between each end or end face 14 of the guide profile and the adjacent bore 130A is equalized or normalized. As a result, the guide profile 1 about an axis 15 transversely to the longitudinal axis of the guide profile by 180 ° as shown by the arrow C, rotatable, so that the guide profile 1 can be used both as a left guide profile la and right guide profile lb (see Figure 4). As can be seen from FIG. 1C, the bores 130 are conical, with a cross section of the borehole 130 being reduced from an inner side 120, which lies opposite the central side surface 12, to the central side surface 12, which represents the outer side 121. Accordingly, the bore 130 in the side surface 10 is formed so that the bore on the inside, which faces the space enclosed by the profile 1, has a larger diameter than on the outer side surface 10. Thus, a screw 16 with a conical screw head 160 flush into the bore 130 so that the friction of the carriage along the drill string is minimized.

2 shows a support unit 2, which comprises a metal plate 20 and two rectangular rolling rails 30, wherein the metal plate 20 with the rolling rails 30 of the carriage over Screws 23 is connected. The support unit 2 has an upper side surface 21 and vertical side surfaces 31, which are at the same time the side surfaces of the respective rolling rails 30. The rolling strips 30 also have side surfaces 32 along their longitudinal extent. The extension LI of the carrying unit 2 including the rolling rails 30 in the horizontal direction, ie parallel to the top 21 of the support unit 2 is in the range of 100 cm to 200 cm and is adapted to the respective spatial conditions. The length L2 of the rolling rails 30 in the vertical direction is advantageously in the range of 50 cm to 100 cm, so that a reliable guidance of the carriage between the guide profiles la, lb can be ensured and prevents tilting of the carriage within the guide profiles la, lb becomes. At the top 21 of the support unit 2 and on the front side of the rolling rails 30 fixing devices, in particular holes 4 are provided for attaching working and / or functional devices.

FIGS. 2A and 2B show the production of the carrying unit 2 from FIG. 2. The carrying unit 2 is produced from a folded metal plate 23 which receives two first folds 24 and two second folds 25. The distance C between the first folds 24 corresponds to the length of the longitudinal edge 312 of the side 31 of the rolling bar 30. The distance D between the first folds 24 and the respectively adjacent second fold 25 corresponds to the shorter edge 313 of the side 31 of the rolling bar 30 in the depth direction. The sum of the distances between each of the second fold 25 and the edge 26 of the metal plate 23 corresponds to the distance C between the first two folds 24 or is smaller to leave a clearance, or is larger to form an overlap. It can be seen in FIG. 2B that the fourfold-folded metal plate 23 encloses the rolling strips 30 on their sides aligned perpendicular to the side 31. The rolling rails 30 are connected to the metal plate 23 via the screws 23.

Figures 3A and 3B show a rolling bar 30 in side view and sectional view, wherein in Figure 3B in addition a part of the guide profile lb is shown. The rolling bar 30 is formed as a block or casting, with a vertically oriented side surface 31. In addition, the rolling bar 30 includes a total of six rollers 33, 34, 35, 36, 37, 38, wherein three rollers 33, 34, 35 in an upper region and three of the rollers 36, 37, 38 are disposed in a lower portion of the side surface 31. The rollers 33, 38 are arranged with its axis of rotation perpendicular to the side surface 31 and the longitudinal axis of the rolling bar 30 and project beyond the edge 311 of the side surface 31 and the folded metal plate 20. The rollers 34, 37 also have an axis of rotation which is perpendicular to the side surface 31 and the longitudinal direction of the rolling bar 30. However, the axes of rotation are offset relative to the longitudinal axis relative to the axis of rotation of the rollers 33, 38, so that the rollers 34, 37 project beyond another edge 310 of the side surface 31. The axis of rotation of the rollers 35, 36 are aligned parallel to the side surface 31 aligned. This arrangement of the rollers allows the two rollers 33, 38 to be in contact with an inner side of the guide profile 1 opposite the outer side surface 11 while the rollers 34, 37 are in contact with the other inner side opposite the outer side surface 10. The rollers 35, 36 touch the middle side surface 12 opposite inner side of the guide rail lb. The six rollers ensure that a frictionless and defined movement of the carriage along the guide profile 1b is ensured, whereby tilting of the carriage relative to the guide profile 1b is prevented. The rollers are advantageously designed as metal wheels or plastic wheels with or without tires.

Figures 3A and 3B also show a suspension device 5 in the form of a pulley. In addition, a fixing device 4 for attachment of working and / or functional surfaces is shown. Figure 4 now shows the entire lifting system with a left and a right guide profile la, lb, a run pour with a support unit 2 and a right and a left suspension 5a, 5b, a pulley system with three fixed pulleys 60a, 60b, 60c, a Cable 61 and a winch 62 and a drive 7. The cable 61 is attached to a ceiling 80 at a first end 610. Subsequently, the rope 61 is wound around the loose right roll 5b, around the fixed roll 60c, the fixed roll 60B, the loose left roll 5a and the fixed roll 60a, the fixed rolls 60a, 60b, 60c being respectively attached to the ceiling 80 of FIG Spatial or a transverse strut (not shown) are attached. The other end of the rope 61 is wound around the cable drum 62. By rotating the axis of rotation of the fixed roller 60a in the vertical direction, the outgoing cable 61 running to the cable drum 62 can be modified in its running direction so that an assembly of the drive 7 is also possible at a possibly more accessible place on a side wall perpendicular to the mounting wall , With the help of the drive 7, which may be attached to the drill bar 13 of the guide profile la, the support unit 2 along the arrow D can be moved up and down. The rope course takes place via four deflection rollers in the sense of a To reduce both the lifting power and to achieve a uniform force distribution, as well as to ensure a controllable, slow lifting and lowering speed. The drive 7 is described in more detail in FIG. Thus, the cable drum 62 laterally on a gear 620, which is coupled to a worm gear 70. Due to the built-in worm gear 70, the cable drum is self-locking and locking, ie without active, aware rotational movements on the drive worm winding or unwinding of the cable drum 62 is not possible, so that the safety of the user is guaranteed. Via a flattened reduction gear 71, the lifting mechanism can also be driven by means of torque weaker, commercially available cordless drills and special bits.

FIG. 6 shows a garage with a ceiling 80, a tilt-resistant wall 81 and a floor 82 in which a car 83 is parked. On the tilt-stable wall 81, a rail system, of which only the guide profile la is shown mounted. Within the rail system, a carriage is guided (not shown) on which a working and / or functional unit 9 is arranged, which serves as a storage surface for an object 84. To increase the authorized carrying load of the working and / or functional unit, a strut 91 is provided, which fixes the loading plate 90, which is arranged pivotably on the support unit 2. Above the guide profile, the pulley system 6 is indicated.

As a working and / or functional unit, various embodiments are conceivable, which are shown in Figures 7A to 7G. For example, a ball head for a bicycle carrier 900 may be attached to the carrying unit 2 that is movable up and down (see FIG. 7A). Alternatively, a storage device 901 may be formed on the support unit 2, which has a support device 9010, which is aligned perpendicular to the storage device 901 and bears against the support unit 2. The tray 901 can be provided, for example, for a ski box 85 or a boat 86 (FIGS. 7B, 7C). Alternatively, the storage unit can be used as a stowage device for tools or as a work surface 87 (see Figures 7D). As shown in FIG. 7E, as a functional unit, a tire holder 902 can also be attached to the carrying unit 2, wherein tires 88 are placed on the holder 902. FIG. 7F shows a further tray 903, which is used to carry storage boxes 89 can be used. The work and / or functional units presented in FIGS. 7A to 7F are primarily intended for use in garages, cellars or garden sheds.

In contrast, Figure 7G shows an application of fiction, contemporary Hebesstems in an apartment that is limited in space. Thus, the lifting system according to the invention can be designed as a bed lifting mechanism 904. With the help of the lifting mechanism, which has a bed as a functional unit, the bed can be moved up and down and the space below the bed lever mechanism 904 can be used with a fold-out desk. This considerably increases the limited space, for example, of a student room.

The possibilities of use are extremely varied and can be expanded as needed. The primary consideration is a lift platform which can be lowered flush with the floor and thus, e.g. also for winter storage of a motorcycle, scooter, or heavy garden equipment (such as lawn tractor, beach chairs) can be easily traveled and loaded. Thus, a weather-protected, secure additional usable area of about 2 square meters in a lockable garage or a small room can be obtained.

FIGS. 8A to 8D show various applications of the working and / or functional units corresponding to FIGS. 7A to 7C and 7E in the corresponding sequence. FIG. 8A shows the carrying unit 2 with a ball head coupling 900 arranged on the carrying unit 2, as used, for example, in motor vehicles. The ball-and-socket coupling 900 can be used, for example, to receive a bicycle carrier, which is fastened to motor vehicles on the trailer coupling.

FIG. 8B shows a storage device 901 for a car roof box 85 with car roof supports 85a. The storage device 901 is designed in the form of prongs, which are arranged on the carrying unit 2 and have support devices 9010 to prevent sinking or bending downwards.

FIG. 8C shows, in accordance with FIG. 7C, a storage device with special receiving devices 901a for a boat 86, the storage device again being designed in the form of prongs which are suspended in the carrying unit 2 and provided with corresponding supporting devices 9010. The embodiment of FIG. 8D corresponds to that of FIG. 7E, wherein the carrying unit 2 has a plurality of holders 88 for tires 88. FIG. 9 shows a safety device 100 which can be inserted into the guide profiles 1 in order to shake the guide or prevent the carrying unit from further movement. The fuse 100 is formed, for example, from a plastic body having a handle 101 and one or more hooks 102 adapted to pass through the drill holes 130 of the drill track of the guide profile 1. As shown in the cut-out portion 110 of the guide rail 1, the securing member 100, when inserted with the hooks 102 into the bores 130 of the guide profile 1, prevents the guide rollers 38 and 37 from moving along the guide profile 1. In this way, the guide carriage or the support unit can be prevented from further movement.

In summary, the fiction, contemporary lifting system and its individual components is characterized by the fact that they provide an effective storage space in confined environments, which can be used in particular for heavier units. A big advantage of this system is that it is easy to manufacture and in particular easy to set up. In addition, the system offers a variety of uses, so it is universally applicable.
