Description

The present invention relates to a work aid according to the preamble of claim 1.

Working aids with a support for a workpiece are used in a variety of ways in trade, industry and at home in order to be able to carry out certain activities easily, comfortably and/or at all.

There are different tools for different applications, but there is a requirement for a workpiece.

It is the object of the present invention 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 design, inexpensive in construction and easy to use and easy to understand.

This object is achieved with the work aid according to claim 1 according to the invention. Advantageous developments are specified in the dependent claims and in the following description together with the figures.

On the part of the inventors, it was recognized that this problem can be solved in a surprising manner in a particularly simple manner if the working aid has pivotable feet, because it can then be easily adapted to specific ground conditions. In addition, it can be easily reduced in size and thus easily transported.

The work tool according to the invention with a stand that has a longitudinal axis, with a stand element for placing the work tool on a floor and a support for a workpiece being arranged on the stand, is characterized in that the stand element has at least three feet, which in relation to the longitudinal axis can be pivoted from a pivoted-out position into a pivoted-in position. With three feet, the stand can be easily adapted to different, adapt in particular to uneven floors. If there are four or more feet, the load supported by the work aid is distributed particularly well.

In an advantageous development, it is provided that the feet are designed to be fixable in the pivoted-out position and/or in the pivoted-in position. As a result, the status of the work tool on a floor is particularly safe.

In an advantageous further development, it is provided that the feet rest in a form-fitting manner on the stand element in the pivoted-out position. As a result, the standing of the working aid on a floor is particularly safe, even with high loads from the workpiece.

In an advantageous further development it is provided that the feet are accommodated in corresponding guides, with the feet having a slot through which an axis of the respective guides extends for pivoting the foot accommodated in the guide. As a result, the pivoting can be carried out very easily and safely.

In an advantageous development, it is provided that the guides have an opening in relation to the longitudinal axis above and below the axis for the passage of the corresponding foot in its pivoted-in position. As a result, the work aid is particularly compact when the feet are in the swiveled-in position, while still ensuring that the stand element can withstand high loads.

In an advantageous development, it is provided that the guides have a support against pivoting of the foot in relation to the axis between the longitudinal axis and the axis below the corresponding foot arranged in its pivoted-out position. As a result, the standing of the working aid on a floor is particularly safe, even with high loads from the workpiece.

In an advantageous development, it is provided that the guides have a support against pivoting of the foot in relation to the axis opposite the longitudinal axis above the corresponding foot arranged in its pivoted-out position. This also makes it particularly safe for the work aid to stand on a floor, even with high loads from the workpiece.

In an advantageous development, it is provided that the feet are inserted into pockets on the stand element in the pivoted-out position. As a result, the standing of the working aid on a floor is particularly safe, even with high loads from the workpiece.

In an advantageous development it is provided that a fixing means is arranged on the axle, which is preferably designed as a nut for clamping the foot in the guide. As a result, the status of the work tool on a floor is designed to be even safer because it prevents it from swiveling in accidentally.

In an advantageous development, it is provided that the guide has two legs that run plane-parallel, with the foot preferably being designed as a sheet metal part. As a result, the standing element is structurally particularly simple and at the same time stable.

In an advantageous development, it is provided that there are stops for the feet in their pivoted-out position on the stand, with the stops preferably being surrounded on all sides by the corresponding guide. This also further improves the stability of the working aid.

In an advantageous development, it is provided that the stand is designed to be telescopic with at least one stand part running in another. Then the work tool can be easily adapted to many different activities.

In an advantageous development, it is provided that the stand is led out to the floor via the guides. As a result, the work aid is designed to be particularly stable, even with high workpiece loads and for different heights. In particular, the stand could be arranged in the same plane as the feet when the feet are in the pivoted-out state, so that the working aid not only stands on the feet but also on the stand itself.

In an advantageous development, it is provided that the stand part running in the other stand part has a plurality of openings which are equally spaced from one another and in the other stand part there is an opening through which a bolt can be pushed, the bolt preferably being designed to be securable and preferably having a stop and opposite the stop an opening for a safety pin. As a result, the work aid can be set and secured at different heights particularly quickly and with repeatability. The distance between the openings is preferably in the range from 10 mm to 50 mm, preferably in the range from 20 mm to 30 mm and is in particular 25 mm.

In an advantageous further development it is provided that a stand part has a thread in which a threaded rod is arranged, with a nut preferably being arranged on the threaded rod for countering against the stand part. As a result, the height of the work aid can be adjusted particularly finely. The thread pitch is preferably in the range of 1.0 mm to 5.0 mm, preferably in the range of 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, an opening distance of 25 mm is compensated for over 10 turns of the thread.

In an advantageous further development it is provided that the support has two first rotatable elements. As a result, workpieces can be guided particularly easily over the support. Independent protection is claimed for this configuration. In the context of this independent protection, it is therefore not important whether the stand element has at least three feet, which are arranged in relation to the longitudinal axis from a pivoted out position into a pivoted position, but it is only obligatory that the support has two first rotatable has elements.

In an advantageous development, it is provided that the distance between the first rotatable elements is selectively adjustable. As a result, the support can be easily adapted to workpieces of different sizes.

In an advantageous further development it is provided that the axes of the first two rotatable elements lie on one line or on two different lines. If the axes of the rotatable elements are on a line, workpieces can be transported particularly easily over the support between the two rotatable elements.

For example, pipes or similar workpieces, in particular for cutting to length, sawing, etc., can be guided safely as a result. Application examples for this are: capping, sawing and flexing, as well as the storage of larger and heavy materials when processing them for processing, such as milling.

If the axes of the rotatable elements lie on different lines, workpieces can be rotated between the two rotatable elements, particularly on the support, about a longitudinal axis of the workpiece. Then, for example, a "rolling" of the workpiece between the two axes is possible. For example, you can place a pipe on a welding table in order to weld round lids with an electrode without detaching or in the TIG welding process without detaching. Furthermore, in this embodiment, the weld seams can then be processed on a grinding machine.

In an advantageous development, it is provided that there are four first rotatable elements, with two first rotatable elements each lying on a common axis and the two axes being spaced parallel to one another. Then both a workpiece transport over the support and a workpiece rotation can be carried out, depending on how the workpiece is placed on the first rotatable elements.

An advantageous development provides that there is a pivoting element on which a second rotatable element is arranged, the second rotatable element being moved from a rest position below the bearing surface of the first rotatable elements to a working position above the bearing surface of the first rotatable elements with the aid of the pivoting element is pivotally arranged, wherein the rest position and / or the working position are preferably designed to be fixed. Workpieces can then be guided in a very defined manner on the support between the first rotatable elements and the second rotatable element. If necessary, workpieces can also be placed and transported directly on the second rotatable element. If the second rotatable element is designed as a wide roller, materials that are flat and wide can also be unrolled, such as flat iron, square tubes, boards, beams, etc. These workpieces can then be easily cut to length.

Independent protection is also claimed for this configuration. In the context of this independent protection, it is therefore not important whether the stand element has at least three feet, which are arranged in relation to the longitudinal axis from a pivoted out position into a pivoted position, but it is only obligatory that the support has two first rotatable has elements. In addition, it is not important whether the support has two first rotatable elements.

In an advantageous further development it is provided that the first rotatable elements and/or the second rotatable element are designed as a wheel or roller. As a result, the corresponding workpieces can be stored and transported very easily on the work aid.

In an advantageous development, it is provided that the pivoting element has two supports, in each of which one, preferably two, slot guides are arranged. As a result, the pivoting and/or adjustment of the orientation of the second rotatable element relative to the first rotatable elements can be carried out very easily.

In an advantageous further development it is provided that the supports are pivotably arranged on an axis of the support. This also makes it very easy to pivot and/or adjust the orientation of the second rotatable element relative to the first rotatable elements.

In an advantageous further development it is provided that the supports rest on two shelves when the pivoting element is in the rest position and are held between the shelves in the working position, with the shelves preferably enclosing the supports in a form-fitting manner. As a result, the work aid is designed to be particularly stable even when the second rotatable element is used.

In an advantageous further development it is provided that the supports in the working position extend upwards beyond the second rotatable element in relation to the longitudinal axis. The supports then also form a guide for the workpiece, so that it can be placed and transported more easily and securely on the working aid. If, on the other hand, the supports in the working position do not have the second in relation to the longitudinal axis rotatable element extend upwards, then workpieces can also be placed and transported on the second rotatable element, which have a greater width than the second rotatable element.

In an advantageous development, it is provided that there is a cover that can be optionally arranged and removed above the first rotatable elements, preferably in the form of a cover plate. The work tool can thus also be used to store workpieces that are not transported on the work tool, but are only intended to be set down or supported. In this way, for example, sheetrock can also be laid down and cut to size with the aid of a plurality of working aids 10 .

In an advantageous further development it is provided that the cover has an opening for fastening a pressure plunger, which is preferably provided with a buffer element. Sensitive workpieces can then also be placed on the work aid. Workpieces can also be placed or supported in a defined manner on a relatively small support point.

a detailed view of the tool 1 in a fifth operating state.

In the Figures 1 to 9 the working tool 10 according to the invention is shown purely schematically in various views.

It can be seen that the working aid 10 has a stand 12 with a longitudinal axis L, a stand element 14 being arranged at the bottom of the stand 12 and a support 16 for a workpiece (not shown) 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 run into one another telescopically. To be more precise, the third column part 22 runs in a form-fitting manner in the second column part 22 and the second column part 20 runs in a form-fitting manner in the first column 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 cotter pin 28 . As a counterpart to the locker there is a stop 30 on the bolt 26 which, when the bolt 26 is inserted, rests in the opening 24 on the first stand part 18 .

The second stand part 20 has continuous openings 32 arranged in a specific grid, which have the same diameter as the opening 24, so that the bolt 26 can engage both through the opening 24 and through one of the openings 32.

At the head 34 of the third stand part 22 there is an internal thread (not shown) into which a threaded rod 36 of the support 16 is screwed. The threaded rod 36 is firmly connected to the support 16, in particular welded.

Between the second stand part 20 and the third stand part 22 there is also a bolt 38 with an opening 39 for a cotter pin 40 and a stop 42 in order to determine the extension height. For this purpose, the third stand part 22 also has openings 44 correspondingly arranged in the same catch.

In addition, there are locking screws 46, 48 on both the first stand part 18 and the second stand part 20, with which the second stand part 20 is clamped in the first stand part 18 and the third stand part 22 in the second stand part 20, respectively. There is also a lock nut 50 with which the extension of the threaded rod 36 from the head 34 of the third stand part 22 can be fixed by countering against the head 34 .

In a preferred variant, the first stand part 18 has a square outer cross section of 40 mm x 40 mm with a wall thickness of 2 mm, the second stand part 20 has a square outer cross section of 35 mm x 35 mm with a wall thickness of 2 mm and the third stand part 22 has one square external cross-section of 30 mm x 30 mm with a wall thickness of 2 mm. The internal thread consists of a metric nut M20 x 2.5, so that the threaded rod is also designed as M20 x 2.5, i.e. it has a pitch of 2.5 mm for a complete revolution. The grid of the openings 32, 44 is 25 mm.

The stand can thus be adjusted via the stand parts 18, 20, 22 at intervals of 2.5 mm and the fine adjustment in the range of 2.5 mm is carried out by turning the threaded rod 36 in the internal thread, with a quarter turn producing a stroke of approx. 6 mm causes.

In another preferred variant, the first stand part 18 has a square outer cross section of 60 mm x 60 mm with a wall thickness of 2 mm, the second stand part 20 has a square outer cross section of 55 mm x 55 mm with a wall thickness of 2 mm and the third stand part 22 a square external cross-section of 50 mm x 50 mm with a wall thickness of 2 mm. The internal thread consists of a metric nut M30 x 3.5, so that the threaded rod is also designed as M30 x 3.5, i.e. it has a pitch of 3.5 mm for a complete revolution. The grid of the openings 32, 44 is 35 mm.

The stand can thus be adjusted via the stand parts 18, 20, 22 at intervals of 2.5 mm and the fine adjustment in the range of 2.5 mm is carried out by turning the threaded rod 36 in the internal thread, with a quarter turn producing a stroke of approx. 6 mm causes.

The stand element 14 comprises four feet 52, each of which has a support element 54 with a footprint 56 arranged thereon. At the end of the feet 52 opposite the positioning surfaces 56, the support elements 54 are beveled 58 in such a way that the support elements 54 are in the pivoted-out state (cf. 2 and 4 ) of the support elements 54 rest against the first stand part 18 in a form-fitting manner.

The support elements 54 are each surrounded by a guide 60 which consists of two plates 62a, 62b which are arranged plane-parallel and 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.

Furthermore, the guides 60 are welded to the first stand part 18 in such a way that an enclosure 66 results for the support element 54 which is in positive contact with the first stand part 18 in the swiveled-out state. These enclosures 66 thus form insertion pockets 66 for the support elements 54, so that they are additionally supported in the pivoted-out state. Between web 64 and enclosure 66 there is an opening D through which the respective foot 52 can be inserted in its pivoted-in position.

Except for the web 64 and the skirt 66, the panels 62a, 62b have no direct connection, so that the support members 54 can pivot freely between the panels 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 a slot guide (not shown) which extends parallel to the longitudinal extent of the support elements 54 and through which the screw 68 is guided.

As a result, the feet can be pulled out of the pockets 66 in the swung-out state when the clamp 67 is released. Subsequently, the support elements 54 can be pivoted down to the first stand part 18 and possibly pushed up and again be clamped by tightening the toggle nut 70 (cf. the right-hand side in 1 and 5 ).

When fully swung out and pushed into the pockets 66 , the support elements 54 are in positive contact with the first stand part 18 . They also engage in the pockets 66 in a form-fitting manner and lie against the web 64 (cf. 2 and 4 ). They can be additionally secured by the clamp 67, with the two plates 62a, 6b clamping the support element 54 in a form-fitting manner.

Due to this special design, the feet 52 can absorb heavy loads and are still easy to swivel and only require a small amount of space when swiveled in (cf. 1 and 5 ) on.

The first stand part 18 extends over the enclosures 66 of the feet 52 and forms a further foot 72 which is provided with a buffer 74 . This foot 72 serves as security if the feet 52 cannot withstand a certain load from a supported workpiece, which is why the foot 72 ends somewhat above the level of the swiveled-out shelves 56 (cf. 2 ). Alternatively, the foot 72 could also end in the same plane as the pivoted-out shelves 56 .

In connection with the Figures 6 to 9 the support 16 according to the invention will now be described in more detail.

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 bottom plate 80 of the base 78 via screw connections 84 . These flanges 82 each have buffers 84 at their ends for safety reasons. In addition, an opening 86 is arranged centrally in the flanges 82 .

On the side faces 88a, 88b of the base 78 there are U-shaped holders 90a, 90b, through the side faces 92 of which openings (not shown) run. A long nut 94 is arranged between the side surfaces 92 .

Furthermore, two oblong holes 96 arranged opposite the holders 90a, 90b bind to the side faces 88a, 88b, with axes 98 being accommodated in opposite oblong holes 96 of the two side faces 88a, 88 in the longitudinal direction of the oblong holes 96 so as to be displaceable. These axles 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 retained in long nut 94, with opposing threaded rods 106 having opposite threads (not shown). As a result, the distance between the opposing axes 98 can be changed continuously by rotating the long nut 94 .

Two wheels 112a, 112b are arranged at a distance from one another on the axles 98, so that there is a gap 114 between the wheels 112a, 112b of an axle 98 (cf. 7 ). In turn, there is a gap 116 between the two axes 98 (cf. 6 ), whose width - as described above - can be changed by the long nut 94.

Also screwed 122 to each of the two side faces 88a, 88b are two shelves 120 which are connected to one another by a sheet metal 118 and are arranged horizontally adjacent.

Above the shelves 120 is a stop 124 with an internal thread (not shown) into which the threaded rod 126 of a knurled nut 128 can be screwed. A support 130a, 130b with a slot 132 is slipped onto the threaded rod 126 and can be clamped against the stop 124 by means of the knurled nut 128.

The two opposite supports 130a, 130b form a pivoting element 134 for a roller 136, the axis 138 of which is guided in elongated holes 140 of the supports 130a, 130b. The axle 138 has an external thread (not shown) on both sides, onto which knurled nuts 142 are screwed, so that the position of the axle 138 in the elongated holes 140 can be fixed.

With the help of pivoting element 134, roller 136 can be rotated from an in 6 rest position shown, in which the supports 130a, 130b rest on the corresponding shelves 120, respectively and the axle 138 below the contact surface of the wheels, can be transferred to a working position in which the roller 136 is above the contact surface of the wheels 112a, 112b and the supports 130a, 130b are held on both sides in a form-fitting manner between the shelves 120.

To transfer from the rest position (cf. 6 ) In the working position, the clamping with the knurled nut 128 is released and the supports 130a, 130b are first pulled up to the threaded rods 126 with their lower ends 144. Then the pivoting element 134 is pivoted into the vertical and then the supports 130a, 130b are lowered onto the threaded rods 126 up to the upper end 146 of the slot 132 and the knurled nuts 1128 are tightened and thereby fixed against the stop 124 by clamping again (cf. 7 ).

The axis 138 can be aligned with respect to the supports 130a, 130b through the elongated holes 140 in such a way that the supports 130a, 130b either protrude vertically over the roller 136 (cf. 7 , left side) or below the storage level of the roller 136 (cf. 7 , right side).

Furthermore, there is a cover 148 designed as a cover plate, which has a central horizontal section 150 and two sections 152a, 152b running inclined thereto. Threaded rods 154 are welded to the inclined sections 152a, 152b, which extend downwards and can be inserted through the openings 86 in the flanges 82.

The four projections 156 arranged on both sides serve as insertion aids or insertion aids for the cover 148 on the flanges 82, each adjoining a wheel 112a, 112b when being attached. The threaded rods 154 are spaced apart to fit within the gaps 114, respectively. After the threaded rods 154 have been inserted into the openings 86, the threaded rods 154 can be fixed in place by means of appropriate nuts (not shown).

Finally, the cover 148 has a central opening 158 with an internal thread (not shown) into which a plunger 160 can be screwed, which for this purpose has a buffer element 162 which is fixed to a threaded rod 164, wherein the screwing of the threaded rod 164 into the opening 158 can be countered by means of a nut 166 (cf. 9 ).

The length of the first column part 18 is 620 mm up to its upper edge, the length of the second column part 20 is 520 mm up to its upper edge and the length of the third column part 22 is 730 mm up to the upper edge of the wheels 112a, 112b, 740 mm up to the Top edge of the cover 148, 790 mm to the top edge of the roller 136 and 820 mm to the top edge of the plunger 160. The total height of the device when fully deployed is 1960 mm. Then the threaded rod 36 is unscrewed to the maximum. It can be adjusted by a total of 75 mm.

In its lowest setting with the feet 52 swiveled out, the working aid 10, with the second stand part 20 and the third stand part 22 each being lowered, has a height of 778 mm up to the top edge of the wheels 112a, 112b, 784 mm up to the top edge of the cover 148 and 810 mm up to the upper edge of the roller 136.

Instead of the plunger 160, a small jack (not shown) can be securely positioned on the area of the cover plate 148, which is 100 mm x 120 mm. For example, the jack is 150 mm high and has a stroke of 100 mm. The base of the jack is 90 mm x 90 mm and is commercially available as such.

Tool 10 is now used as follows:
When the feet 52 are pivoted in, the entire device 10 with all additional parts can be accommodated in a holder 76 and transported (cf. 3 ), whereby a lid is used to close the quiver 76 (in 3 Not shown). Cases 76 with a lid have an outside diameter of 200 mm and a length of 900 mm. The height of the working aid 10 in the pivoted-in state of the standing element 14 up to the wheels 112a, 112b is 775 mm, while the working aid 10 reaches a maximum height of 1,880 mm.

After the quiver 76 has been opened, the working aid 10 is removed and the feet 52 are swung out after loosening the toggle nuts 70 , inserted into the enclosures 66 and fixed again with the toggle nuts 70 . Subsequently, by loosening the screws 46, 48 the stand 12 is telescoped approximately to a desired length and first fixed by inserting the bolts 26, 38 into the openings 24, 32, 44 and then by the corresponding cotter pins 28, 40 and tightening the locking screws 46, 48 secured. The exact height is then determined by screwing the threaded rod 36 in or out of the head 34 of the third stand part 22 and this position is secured with the aid of the lock nut 50 .

Depending on the application, the design of support 16 is now selected:
If a delicate workpiece (not shown) is to be supported, the plunger 160 with the buffer element 162 is selected for this purpose.

Conversely, if a non-sensitive workpiece (not shown) is to be supported from below, the plunger 160 can be removed from the cover 148 and the workpiece supported directly on the cover 148.

These two variants are primarily used for static workpieces that are not to be moved on the support 16.

The roller 136 is used for workpieces to be moved (not shown) that are flat. For this purpose, the pivoting element 134 is released by loosening the knurled nuts 128, the lower end 144 of the supports 130a, 130b is pulled against the threaded rods 126 and the pivoting element 134 is pivoted into the vertical. Thereafter, the pivoting element 134 is lowered, as a result of which the upper end 146 of the elongated holes 132 strikes the threaded rod 126 and the supports 130a, 130b are held between the two shelves 120 in a form-fitting manner. Finally, the knurled screws are tightened again and the position of the pivoting element 134 is thus secured.

The roller 136 now rests on and is supported by the wheels 112a, 112b with rotation of the roller 136 being transmitted to the wheels 112a, 112b.

In the event that a lateral protection of the workpiece against lateral sliding off the roller 136 is to take place, the supports 130a, 130b are not connected to the upper end 146 of its slot 132 on the shelves 120, but shifted up so far that they protrude beyond the roller 136 upwards.

For this purpose, the position of the roller 136 in the supports 130a, 130b is fixed in each case by shifting the axis 138 in the elongated holes 140 and secured by means of the knurled nuts 142.

For workpieces to be moved (not shown), which have a round, oval, square or almost square cross-section and are relatively long, a support is either in the slot 116, the width of which can be adjusted by actuating the long nut 94, or the Support takes place in the slots 114.

The first type of support in the slot 116 is suitable, for example, for processing the weld seams of a pipe, while the second type of support in the slots 114 is suitable, for example, for cutting pipes or the like to length.

Finally, workpieces can also be clamped between the wheels 112a, 112b and the roller 136.

With all support variants, two or more work aids 10 can also be used to support large workpieces (not shown). This could, for example, be used to store plasterboard for cutting.

It has become clear from the above description that the present invention provides a work aid 10 that can be used for numerous different work cases. The working aid 10 can be used in a mobile manner and is easy to transport. In addition, it is simple in structure, inexpensive in construction and easy to use and easy to understand.

The claims filed now with the application and also the claims filed later are without prejudice for the attainment of further protection.

If a closer examination, in particular of the relevant state of the art, should show that one or the other feature is for the purpose of the invention favorable, but not decisively important, a formulation is of course already being sought which no longer has such a feature, in particular in the main claim. Such a sub-combination is thus also covered by the disclosure of this application.

The references listed in the dependent claims indicate the further development of the subject matter of the main claim through the features of the respective dependent claim. However, these are not to be understood as a waiver of the achievement of independent, objective protection for the features of the subclaims that refer back.

It should also be noted that the configurations and variants of the invention described in the various embodiments and shown in the figures can be combined with one another as desired. One or more features can be arbitrarily interchanged with one another. These combinations of features are also disclosed.

Features that were only disclosed in the description or individual features from claims that include a plurality of features can be included in the independent claim(s) at any time as being of essential importance to the invention for delimitation from the prior art, even if if such features were mentioned in connection with other features, or achieve particularly favorable results in connection with other features.

Thus, all of the features presented in the general description of the invention, the description of the exemplary embodiments, the following claims and in the figures can be essential to the invention both individually and in any combination with one another. These features or combinations of features can each constitute an independent invention, which we expressly reserve the right to claim. Individual features from the description of an exemplary embodiment do not necessarily have to be combined with one or more or all other features specified in the description of this exemplary embodiment; in this regard, each sub-combination is also expressly disclosed. Objective features of a device can also be reworded and used as process features Process features can be reformulated and used as concrete features of a device. Such a reformulation is thus automatically disclosed.
