Definitions

  • the present invention relates to a working aid according to the preamble of claim 1.
  • Work aids with a support for a workpiece are used in a variety of ways in trade, industry and the home to enable certain activities to be carried out easily, comfortably and/or at all.
  • the object of the present invention is to provide a work aid that can be used for numerous different work cases.
  • the work aid should preferably be mobile and easy to transport. In particular, it should be simple in structure, inexpensive in construction and comfortable and easy to understand to use.
  • the inventors realized that this task can be solved in a surprising and particularly simple way if the support has two first rotatable elements. This makes it particularly easy to guide workpieces over the support.
  • the work aid according to the invention with a stand which has a longitudinal axis, wherein a stand element for placing the work aid on a floor and a support for a workpiece are arranged on the stand, is characterized in that the support has two first rotatable elements.
  • the work aid has swivel feet, because it can then be easily adapted to certain floor conditions. In addition, it can be easily reduced in size and thus easily transported.
  • the stand element has at least three feet which are arranged so that they can be pivoted from a swiveled-out position to a swiveled-in position in relation to the longitudinal axis. With three feet, the stand can be adapted particularly easily to different, particularly uneven, floors. If there are four or more feet, the load supported by the work aid is distributed particularly well.
  • the feet are designed to be fixable in the swung-out position and/or in the swung-in position. This makes the work aid particularly safe to stand on a floor.
  • the feet are in a form-fitting position against the stand element in the swiveled-out position. This means that the work aid stands particularly securely on a floor, even when the workpiece is subject to high loads.
  • the feet are accommodated in corresponding guides, whereby the feet have an elongated hole through which an axis of the respective guides extends for pivoting the foot accommodated in the guide. This allows pivoting to be carried out very easily and safely.
  • the guides in relation to the longitudinal axis have an opening above and below the axis for the passage of the corresponding foot in its pivoted-in position. This makes the work aid particularly compact when the feet are pivoted in, while still ensuring a high load-bearing capacity of the stand element.
  • the guides in relation to the axis between the longitudinal axis and the axis below the corresponding foot arranged in its swiveled-out position have a support to prevent the foot from swiveling. This ensures that the work aid stands particularly securely on a floor even when the workpiece is subject to high loads.
  • the guides in relation to the axis opposite the longitudinal axis above the corresponding foot arranged in its swiveled-out position have a support to prevent the foot from swiveling. This also ensures that the work aid stands particularly securely on a floor even when the workpiece is subject to high loads.
  • the feet are inserted into pockets on the stand element in the swiveled-out position. This ensures that the work aid stands particularly securely on a floor, even when the workpiece is subject to high loads.
  • a fixing means is arranged on the axle, which is preferably designed as a nut for clamping the foot in the guide. This makes the stand of the work aid on a floor even safer because it prevents it from swinging in accidentally.
  • the guide has two legs that run parallel to the plane, with the foot preferably being designed as a sheet metal part. This makes the stand element particularly simple in construction and at the same time stable.
  • the stand is provided with stops for the feet in their swiveled-out position, with the stops preferably being surrounded on all sides by the corresponding guide. This also further improves the stability of the work aid.
  • the stand is designed to be telescopic with at least one stand part running into another.
  • the work aid can then be easily adapted to many different activities.
  • the stand extends beyond the guides to the floor. This makes the work aid particularly stable, even with high workpiece loads and for different heights.
  • the stand could be arranged in the same plane as the feet when the feet are swung out, so that the work aid not only stands on the feet, but also on the stand itself.
  • the column part running in the other column part has several equally spaced openings and in the other column part there is an opening through which a bolt can be pushed, wherein the bolt is preferably designed to be lockable and preferably has a stop and an opening for a locking pin opposite the stop.
  • the distance between the openings is preferably in the range 10 mm to 50 mm, preferably in the range 20 mm to 30 mm and is in particular 25 mm.
  • a stand part has a thread in which a threaded rod is arranged, with a nut preferably arranged on the threaded rod for locking against the stand part.
  • the thread pitch is preferably in the range 1.0 mm to 5.0 mm, preferably in the range 1.5 mm to 3.0 mm and is in particular 2.5 mm. With a thread pitch of 2.5 mm, there is a particularly fine adjustment, since a stroke of approx. 0.6 mm is achieved with a quarter turn. In addition, a breakthrough distance of 25 mm is compensated for over 10 thread turns.
  • the distance between the first rotatable elements is designed to be selectively adjustable. This means that the support can be very easily adapted to workpieces of different sizes.
  • the axes of the two first rotatable elements are on one line or on two different lines. If the axes of the rotatable elements are on one line, workpieces can be transported particularly easily over the support between the two rotatable elements. For example, pipes or similar workpieces can be safely guided in this way, particularly for cutting to length, sawing, etc. Examples of applications for this are: cutting, sawing and grinding, as well as the storage of larger and heavier materials during processing for their processing, such as milling.
  • workpieces can be rotated around a workpiece's longitudinal axis between the two rotating elements, particularly on the support. This makes it possible, for example, to "roll" the workpiece between the two axes. This makes it possible, for example, to place a pipe on a welding table in order to weld round covers without setting them down using an electrode or using the TIG welding process without setting them down. Furthermore, with this design, the weld seams can then be machined on a grinding machine.
  • first rotatable elements there are four first rotatable elements, with two first rotatable elements each lying on a common axis and the two axes being arranged parallel and spaced apart from one another. Then, either a workpiece transport over the support or a workpiece rotation can be carried out, depending on how the workpiece is placed on the first rotatable elements.
  • a pivoting element on which a second rotatable element is arranged, the second rotatable element being arranged so as to be pivotable with the aid of the pivoting element from a rest position below the support surface of the first rotatable elements to a working position above the support surface of the first rotatable elements, the rest position and/or the working position preferably being designed to be fixable.
  • Workpieces can then be guided on the support in a very defined manner between the first rotatable elements and the second rotatable element.
  • workpieces can also be placed directly on the second rotating element and transported. If the second rotating element is designed as a wide roller, materials that are flat and wide, such as flat iron, square tubes, boards, beams, etc., can also be unrolled. These workpieces can then be easily cut to length.
  • first rotatable elements and/or the second rotatable element are designed as a wheel or roller. This makes it very easy to store and transport corresponding workpieces on the work aid.
  • the pivoting element has two supports, in each of which one, preferably two, elongated hole guides are arranged. This makes it very easy to pivot and/or adjust the alignment of the second rotatable element relative to the first rotatable elements.
  • the supports are arranged so that they can pivot on an axis of the support. This also makes it very easy to pivot and/or adjust the alignment of the second rotatable element relative to the first rotatable elements.
  • the supports rest on two shelves in the rest position of the pivoting element and are accommodated between the shelves in the working position, with the shelves preferably enclosing the supports in a form-fitting manner. This makes the work aid particularly stable even when the second rotatable element is used.
  • the supports in the working position extend upwards beyond the second rotatable element in relation to the longitudinal axis.
  • the supports then simultaneously form a guide for the workpiece, so that it can be placed and transported on the work aid more easily and safely. If, on the other hand, the supports in the working position do not extend upwards beyond the second rotatable element in relation to the longitudinal axis, then workpieces that are wider than the second rotatable element can also be placed and transported on the second rotatable element.
  • a cover that can be optionally arranged and removed above the first rotatable elements, preferably designed as a cover plate.
  • the work aid can also be used to store workpieces that are not to be transported on the work aid, but only to be placed down or supported.
  • plasterboard can also be stored and cut to size using several work aids 10.
  • the cover has an opening for fastening a pressure stamp, which is preferably provided with a buffer element. This means that even sensitive workpieces can be placed on the work aid. In addition, workpieces can be placed or supported in a defined manner on a relatively small support point.
  • the work aid 10 has a stand 12 with a longitudinal axis L, wherein a stand element 14 is arranged at the bottom of the stand 12 and a support 16 for a workpiece (not shown) is arranged at the top, i.e. opposite the stand element 14.
  • the stand 12 has a first stand part 18, a second stand part 20 and a third stand part 22, which extend telescopically into one another. More precisely, the third stand part 22 runs in a form-fitting manner in the second stand part 22 and the second stand part 20 runs in a form-fitting manner in the first stand part 18.
  • the first stand part 18 has a continuous opening 24 through which a bolt 26 can be pushed, which can be secured with a split pin 28.
  • a stop 30 on the bolt 26 which rests against the first stand part 18 in the opening 24 when the bolt 26 is inserted.
  • the second stand part 20 has continuous openings 32 arranged continuously in a certain grid, which have the same diameter as the opening 24, so that the bolt 26 can reach through both the opening 24 and one of the openings 32.
  • the third stand part 22 Between the second stand part 20 and the third stand part 22 there is also a bolt 38 with an opening 39 for a split pin 40 and a stop 42 to determine the extension height.
  • the third stand part 22 also has openings 44 arranged in the same notch.
  • the first column part 18 has a square external cross-section of 40 mm x 40 mm with a wall thickness of 2 mm
  • the second column part 20 has a square external cross-section of 35 mm x 35 mm with a wall thickness of 2 mm
  • the third column part 22 has a square external cross-section of 30 mm x 30 mm with a wall thickness of 2 mm.
  • the internal thread is on a metric nut M20 x 2.5, so that the threaded rod is also designed as M20 x 2.5, i.e. has a pitch of 2.5 mm for one complete revolution.
  • the grid of the openings 32, 44 is 25 mm.
  • the first stator part 18 has a square external cross-section of 60 mm x 60 mm with a wall thickness of 2 mm
  • the second stator part 20 has a square external cross-section of 55 mm x 55 mm with a wall thickness of 2 mm
  • the third stator part 22 has a square external cross-section of 50 mm x 50 mm with a wall thickness of 2 mm.
  • the internal thread is on a metric nut M30 x 3.5, so that the threaded rod is also designed as M30 x 3.5, i.e. has a pitch of 3.5 mm for one complete revolution.
  • the grid of the openings 32, 44 is 35 mm.
  • the stand element 14 comprises four feet 52, each of which has a support element 54 with a support surface 56 arranged thereon. At the end of the feet 52 opposite the support surfaces 56, the support elements 54 are bevelled 58 so that the support elements 54 in the swung-out state (cf. Fig. 2 and 4 ) of the support elements 54 rest positively on the first stand part 18.
  • the support elements 54 are each surrounded by a guide 60, which consists of two plane-parallel plates 62a, 62b, which are connected to one another via a web 64. This web 64 forms a stop for the support elements 54 when the support elements 54 are pivoted out.
  • the guides 60 are welded to the first stand part 18 in such a way that a frame 66 is formed for the support element 54 which rests positively on the first stand part 18 in the swung-out state.
  • These frames 66 thus form insertion pockets 66 for the support elements 54 so that they are additionally supported in the swung-out state.
  • the plates 62a, 62b have no direct connection whatsoever, so that the support elements 54 can be freely pivoted between the plates 62a, 62b.
  • the plates 62a, 62b have a continuous opening (not shown) through which a clamp 67 in the form of a screw 68 and a toggle nut 70 is guided.
  • the support elements 54 have an elongated hole guide (not shown) which extends parallel to the longitudinal extension of the support elements 54 and through which the screw 68 is guided.
  • the support elements 54 When fully swung out and inserted into the pockets 66, the support elements 54 rest against the first stand part 18 in a form-fitting manner. They also engage in the pockets 66 in a form-fitting manner and rest against the web 64 (cf. Fig. 2 and 4 ). They can be additionally secured by the clamp 67, whereby the two plates 62a, 62b clamp the support element 54 in a form-fitting manner.
  • the feet 52 can support large loads and are still easy to swivel and require only a small amount of space when swivelled in (cf. Fig. 1 and 5 ) on.
  • the first stand part 18 projects downwards over the surrounds 66 of the feet 52 and forms another foot 72, which is provided with a buffer 74.
  • This foot 72 serves as a safety feature in case the feet 52 cannot withstand a certain load from a supported workpiece, which is why the foot 72 ends slightly above the level of the pivoted-out support surfaces 56 (cf. Fig. 2 ). Alternatively, the foot 72 could also end in the same plane as the pivoted-out shelves 56.
  • the support 16 has a base 78 which is designed as a U-shaped channel and is firmly welded to the threaded rod 36.
  • Flanges 82 are arranged on both sides of the base plate 80 of the base 78 via screw connections 84. These flanges 82 each have buffers 84 at their ends for safety reasons.
  • an opening 86 is arranged centrally in the flanges 82.
  • U-shaped holders 90a, 90b are arranged on the side surfaces 88a, 88b of the base 78, with openings (not shown) running through the side surfaces 92.
  • a long nut 94 is arranged between the side surfaces 92.
  • two elongated holes 96 arranged opposite the holders 90a, 90b are connected to the side surfaces 88a, 88b, with axes 98 being accommodated in opposite elongated holes 96 of the two side surfaces 88a, 88 so as to be displaceable in the longitudinal direction of the elongated holes 96.
  • These axes 98 are fixed to one side 100 of legs 102.
  • the other side 104 of the legs 102 has an opening (not shown) through which a threaded rod 106 extends, which is fixed on the other side 104 with two nuts 108, 110.
  • Opposing threaded rods 106 are each held in the long nut 94, whereby the opposing threaded rods 106 have opposing threads (not shown).
  • the distance between the opposing axes 98 can be continuously changed by rotating the long nut 94.
  • Two wheels 112a, 112b are arranged on the axles 98 at a distance from each other, so that a gap 114 is formed between the wheels 112a, 112b of an axle 98 (cf. Fig. 7 ). Between the two axes 98, a gap 116 is formed (cf. Fig. 6 ), the width of which can be changed by means of the long nut 94, as described above.
  • two shelves 120 are screwed 122 onto each of the two side surfaces 88a, 88b and are connected to one another via a sheet metal 118 and are arranged horizontally adjacent.
