Definitions

  • the invention relates to a lifting device according to the preamble of claim 1.
  • Lifting devices with a lifting platform, platform or the like which is height-adjustable on a frame and at least one mast, column or other guide device which projects thereon. are common. An example may be found in EP-A-0 403 410. Such lifting devices are used in workshops and factories, where they are relatively local. However, it would often be desirable to have such lifting devices also available at a remote work station, for example to have them available on site for manual work.
  • the disadvantage of most known lifting devices is that the frame is necessarily a mast (and as a result, a "mast" should always be spoken of here, whatever design the guide device for the lifting platform always has) may have) at an angle, ie normally has to be at a right angle, which makes the lifting device very bulky and hardly suitable for transport.
  • the invention is therefore based on the object of designing a lifting device of the type mentioned at the outset in such a way that transport and handling are facilitated, but at the same time safety is increased. According to the invention, this is achieved by the characterizing features of claim 1.
  • a particularly advantageous embodiment is that according to feature a) of claim 2: on the one hand, this allows an improved and more secure mounting of the mast, which extends over the entire length of the frame, in its rest or transport position. On the other hand, this enables the frame to be pushed together as small as possible for transport. Finally, there is also the possibility of using this telescopic pull-out to enlarge the footprint when in use, in order to improve stability.
  • a frame of unequal length or width i.e. preferably a rectangular frame, it is not absolutely necessary that only the long sides can be telescopically extended, rather it would be, e.g.
  • the broad side or the narrow side extendable, for example in order to also secure the frame against tipping if, for example, the lifting platform around the mast should also be designed to be rotatable or pivotable to reach areas which are otherwise difficult to reach and which are to be processed.
  • the locking device naturally also plays an important role in the design according to the invention. Although it can be designed as desired in the context of the prior art, the locking is facilitated by a design according to claim 2 c). This is because a prism-shaped body carrying the tilt axis, the outer surfaces of which have a certain radial distance from the axis, enables a more secure locking without the locking device having to act on the mast itself, which would be problematic for various reasons.
  • the training according to claim 2 c) gives the possibility of the prism-shaped body as a closed Use housing for the installation of parts to be protected, especially the linear actuator, as cable and wire routing, etc.
  • a frame-like frame 1 which is approximately rectangular. Accordingly, it has two longitudinal spars 2, which are connected to one another via two transverse spars 3, 4.
  • the frame 1 can be moved on rollers 5, as is preferred, but is not absolutely necessary in the context of the invention.
  • the longitudinal spars 2 are preferably formed over at least part of their length as hollow square tubes for guidance for a guide bar 6 each extending into their interior, these bars 6 with the cross bar 4 to form an extendable one Telescopic guide are firmly connected. Therefore, the cross member 4 can be pulled out of the position shown, which it also takes during a possible transport of the lifting device shown to be taken to an external work station, with reference to FIG. 1, for example in order to enlarge the footprint of the frame 1.
  • the telescopic extensibility of the cross member 4 can also have another purpose.
  • a mast 8 On the frame 1 there is a mast 8 forming a guide for a lifting platform 7 from the position of use shown, in which it is angled, in particular angled vertically, relative to the relatively flat frame 1 which defines a substantially horizontal plane (the central plane of the frame 1) to pivot about a tilt axis 9 by about 90 ° in such a way that it comes to lie between the longitudinal spars 2, in the same plane as this.
  • the mast has finite cross-sectional dimensions, it would in itself have to be somewhat shorter in order to pass the crossbar 4 during this tilting movement, but this shortening can be avoided by the crossbar 4 being slightly telescopically extendable in order to allow the mast to move past.
  • the spars 2-4 practically define a single level, if you disregard the strength or height of the spars 2-4.
  • the tilt axis 9 also lies in this plane.
  • the platform 18 serving expediently for covering and can form such a loading area so that the frame 1, with the exception of the optionally attachable rollers 48, has no protruding parts, the mast 8 forms a unit with the frame 1 and the whole device is so easy in a station wagon, a small transporter, yes if necessary, even in a trunk, after folding the rear seats, and can be transported to any place.
  • the Frame at least mainly, made of light metal, such as aluminum profiles.
  • the plug holes 70 shown in FIG. 1 a can be provided in the cross member 4, into which a handle bar 23 shown in FIG. 1 b is inserted and secured by a fastening device known per se (nut, bayonet lock or the like) can, if necessary. In this way, loads can also be transported on the loading platform 18.
  • the training can now be such that the cross member 4 itself takes over the locking of the mast 8 in the transport position shown in Fig. 1b, by the cross member having a free head end of the mast 8 receiving profile, which is telescopic over the free end of the Mastes 8 can be inserted.
  • the cross member 4 is simply designed in the manner indicated by dashed lines at 4 'as a U-profile open towards the interior of the frame and against the mast.
  • Fig. 2 shows more clearly how the cross member 4 at least partially covers the free head end of the mast 8 (cap 39) and thus prevents unwanted opening during transport.
  • a locking device is also assigned to the position of use of the mast 8 shown.
  • pivot bearings are provided on both sides in the longitudinal spars 2 for defining the axis of rotation 9 near the cross spar 3, each of which accommodates an axle stub 10 (only one is visible).
  • This stub axle 10 sits on the end face of a square prism body 11, which is expediently hollow on the inside and thus serves as a housing for parts to be described later.
  • the stub axles 10 do not need to be directly connected to the end face of the prism or U-profile 11, for example welded, rather it is possible to provide bearing blocks 9 'on both ends of the prism 11, into which cylindrical stub axles can also be inserted, as in corresponding (not shown) bearing blocks on the frame 1, as will be discussed later with reference to FIG. 5.
  • the tilt axis 9 lies relatively closely on the transverse side of the frame 2-4 formed by the cross bar 3 or is arranged in the region of the ends of the longitudinal bars 2.
  • the cross member 3 can therefore be dispensed with entirely (cf. FIG. 5), which gives the advantage of a space and weight gain that can be used to move the tilt axis 9 all the way to the end of the longitudinal members 2, in order to enable an even greater length of the mast 8 and, if necessary, to take over the function of securing the transverse stability instead of the cross member 3.
  • the prism body 11 can now also advantageously be used for locking.
  • Various possibilities are conceivable for this purpose, for example by pushing from the side of the longitudinal spars 2 into a corresponding latch opening of the prism body 11 (or vice versa).
  • a locking rod 12 is provided, which is located in a holder 13.
  • the bracket 13 can be made relatively wide to allow the prism 11 to tilt. If the holder in the embodiment shown is designed approximately as a U open at the top, which allows the rod 12 to be inserted, it would also be conceivable as a rail profile closing the rod 12 upwards or as a slot guide, so that the rod with the frame 1 cannot be lost connected is.
  • a secure and play-free locking can be created in that the locking rod 12 has at least one, preferably at least two, schematically indicated threaded holes 14, which are aligned with bores of the prism 11, so that in the position of use of the mast shown 8 screws in this Threaded holes 14 can be screwed in and secure the position. It is advantageous if such locking screws or holes 14 are symmetrical about a central axis running between the two longitudinal spars 2, i.e. expediently arranged at both ends of the locking rod 12.
  • the mast 8 is a box profile formed, the lift 7 with the help of a chain 15 up and down along a guide described later in detail. It would also be conceivable to design the mast as a round column in order to allow the lifting platform 7 to be pivoted, in which case, however, there is a shift in weight. This weight shift can be supported by the already mentioned telescopic design of the frame parts 2-4, but it is also possible to provide additional feet 16. According to the prior art, such additional feet on the frame can be pivoted about vertical pivot axes. However, this means a considerable load for the swivel axes and their bearings, which is at the expense of safety.
  • the feet 16 are designed as plug-in parts that can be inserted into openings 17, which enables a better distribution of forces over a longer distance.
  • the feet 16 can also be fastened to round profiles extending in the direction of the longitudinal bars 2 (or the transverse bars 3, 4) in order to pivot the feet out of a transport position in which the sections of the feet 16 which are angled downward in FIG. 1 can be folded into the plane of the frame 1 for transport. So it would also be possible to captively connect the feet 16 to the frame 1, although other constructions would also be possible for this. It would also be conceivable to provide for the fixation of the frame 1 running on rollers 48 in place of the feet 16 (or in addition to these) acting on the wheels 48 and / or on the floor, brake shoes which can be lowered from the frame 1.
  • an arrangement of the lifting platform 7 which can be rotated about the longitudinal axis of the mast 8 can also be implemented in such a way that the mast 8 itself is rotatably mounted about its longitudinal axis. This could either be done with a manual adjustment and a fixation of the respective rotational position, but a rotary drive can also be provided, in which a toothed turntable is attached to the prism 11, in which the pinion of a motor engages.
  • the lifting platform 7 essentially consists of a platform 18, on the underside of which parking feet 19 are optionally provided. These feet 19 come in the Transport position of the lift in the best visible from FIG. 2 in U-shaped support profiles 20, so that the position of the platform 18 is defined such that it is approximately flush with the top of the frame 1. It is advantageous to provide a railing 21 on the platform 18, and this can be designed as a plug-in part according to FIG. 2, the feet 19 expediently being designed as hollow plug-in profiles which accommodate the plug-in projections 22 of the railing 21.
  • the steering and guide rod 23 already mentioned can be provided in order to be able to move the lifting device as desired, unless one wishes to provide a separate travel drive.
  • a control device for any drives can be fastened to the railing 21 via lines led out of the hollow mast 8 or a separate guide tube, so that it is easily at hand for the user in any position of the lifting platform.
  • the mechanical design of the drive can also be adapted to the circumstances in a variety of ways.
  • An example can be seen in FIG. 3, in which a piston-cylinder unit 18 is arranged inside the mast 8 and parallel to it as the drive source.
  • the piston rod 25 of this unit 24 is connected to the mast 8, specifically here at its head end, so that the mast, as an extension of the cylinder unit 24, can be moved upwards into the position according to FIG. 3B.
  • a further profile can also surround the cylinder 24, as indicated by dash-dotted lines in FIG. 3B.
  • an elastic bellows 40 is provided which covers the cylinder 24 - with the height of the mast 8 and its slide bearings 27, 27 'changing downward over the dash-dotted length.
  • this also has the advantage of saving weight and thus easier portability, for which purpose the various parts and profiles can also be formed from light metal.
  • the mast 8 can also be guided by a hollow rod 26 which engages with a slide bearing 27 at the lower end of the mast 8.
  • this hollow rod 26 is connected at its upper end to the cylinder unit 24 via a cross bracket 28.
  • the cylinder 24 can alternatively or cumulatively serve as a sliding guide, for which reason a further bearing 27 ′ can surround the cylinder 24. If both slide bearings 27, 27 'are provided, it is advantageous to form them in one piece such that they can be assembled together.
  • a collar 29 of the cylinder 24 can serve on the one hand as a support surface for the crossbar 28 and on the other hand as an end stop for the slide bearing 27 '.
  • a lower end stop 30 is provided, against which the slide bearing 27 'bears in the position according to FIG. 3A.
