Description

The invention relates to a universal table, optionally as a normal table, as Work table or as work bar with at least one work station can be used.

Often there is a need for a normal table as a work table or as a work bank is usable. Such a need for universal applicability exists in School operations, in the home improvement area, but also in the craft to do less often occurring work.

A table of the type mentioned is known from DE 196 31 835 C1. This is what it is about is a workbench that has collets, which in the without workpiece closed state are fully integrated into the outer surfaces of the table. The actuator The collets are supplied with hexagon wrenches, which are inserted into a hexagon socket can be introduced. These can be deducted and used as a workbench A normal table or as a work table without collets is possible. This optional Use is very advantageous, especially for school operations. The universality however does not yet meet the often existing diverse needs. As well as School operations as well as in the DIY sector are usually not possible, separate Tables or workbenches for woodworking, metalworking or to provide other work.

The invention is therefore based on the object of a universal table at the beginning mentioned type in such a way that it is as diverse as possible for the implementation, various jobs can be quickly and easily converted.

The object is achieved in that at least one in the area Outside of the table top at least one half of a fastening device is arranged, with which at least one workstation on the outside of the table top  is attachable, which is at least a complementary half of a fastening device tion.

The advantage of the invention is that the universal table with any work stations can be equipped. It can be a small handyman act on one, two or three sides with one or more different table Workstations can be equipped. However, it is also possible to have a large one To be equipped with many workstations across its entire circumference, z. B. several students can work on it simultaneously in school.

The universal table can be used, for example, as a workbench with different work stations are designed for metalwork. Vices are more arbitrary Size, drill stand for hand drills, small bench drills, grinders or other machines or aids. Sheet metal can be used for sheet metal processing shears, especially the smaller roller shears, but also large and small ones Attach straightening plates, driving blocks or folding devices to the table. Farther can use all types of bending devices for wires, rods or sheets, in particular thinner sheets up to approx. 1 mm thick can be provided. There is an appendix to the Workstations on the edge of the table are just as possible as an additional support on the Table, which is useful for any type of hammer work. Leave for woodwork add parallel collets, but also miter saws, miter cutters, Table clamps or jigsaw boards, which can also be height adjustable. It any type of woodworking machine can be attached to the table, too can be designed with the inclusion of a clamped hand drill. Examples include woodturning benches, wood milling machines or saws. The universal table is not limited to use as a table or workbench, it can can be used as a work table for further work. For example, characters boards, holders for paints, brushes, water or oil can be attached so that the table can be used as an easel or for technical drawing. This is especially true in school operations an advantage because a room can be used as a workshop, drawing room or as usual classroom is available. In the hobby area it is by means of the universal table for example possible to set up the basement, which is much too small for the handyman, that he can do almost all conceivable work.  

In order to optimally meet the diverse purposes of the universal table, the invention provides many useful further developments and advantageous events:
For the optimal use of the universal table as a normal table, it is provided that one half of the fastening devices are embedded in at least one outside of the table top. As a result, after the workstations have been removed, the universal table does not have any protruding parts that hinder normal use. In addition, it is of course also possible to provide the recesses of the fastening devices on the outside of the table top with covers. Corresponding to the halves just described, the other halves of the fastening devices are let into the side of a workstation that can be attached to an outside of the table top. This ensures that this part of the fastening device does not protrude on any side of the workstation and is therefore a hindrance. For the same reason, it is also expedient that the fastening devices can be actuated by means of a key which can be inserted into an engagement embedded in the surface. In this way, a protruding actuating lever is avoided and it is possible to design the key in such a way that it is used simultaneously for the actuation of the work station, for example as a vice for a parallel collet or in another way.

There are a variety of possibilities for the design of the fastening devices options. An expedient embodiment provides that one half of the Fastening devices each have at least one rotatable eccentric curve point, each in a holding element of the other halves of the fastening directions engages in such a way that the workstation by rotating the eccentric Curve can be pressed against the outside of the table top. This shape Tungment has the advantage that with a very short travel, a firm and self-holding Locking the workstation on the universal table can be achieved. An arrangement provides that two eccentric curves are mirror images on a rotating disc are arranged, each of which engages in a holding element. This will make one achieved particularly stable, self-retaining fastening.  

Another embodiment provides that the one half of the attachment directions each have a bolt mounted by means of a rotatable eccentric, one grips the other halves of the fasteners, and that by means of the eccentric the work station can be pressed against the outside of the table top. This fastening device ensures a particularly stable hold of the workstation achieved.

Another fastening device is designed such that one half of the Fastening devices each have a locking pin with a transverse one Have a holding rod that slants through an opening in a holding cam with two Levels and two holding surfaces can be inserted. By turning the locking pin the support bar slides on the support surfaces over the inclined planes, thereby the Workstation is pressed against the outside of the table top. This execution form is suitable for engaging the keys on a vertical side of the To attach the workstation. A useful embodiment is that in the Locking pin a threaded rod for adjusting the holding rod is inserted. Thereby this can be adjusted and the clamping force set.

Another embodiment provides that the halves of the bee to be actuated Fixing devices with interventions for the key at the work stations are located. In this way it is achieved that the table top is free of such interference fen, and that the fastening devices on the table are relatively simple that can. This makes it possible to create a universal table with a large number of To provide fasteners without this essential to the universal table more expensive. However, a large number of fasteners have that Advantage that workstations can be attached in many different positions. The Interventions for the key can be arranged on the top of the work station, so that they are easily accessible. The key interventions are expediently called Through holes are formed so that chips fall through and not for actuation are a hindrance.

A more precise positioning of the work stations is achieved in that these additionally have at least one dowel pin that fits into a fitting hole of the Univer saltic intervention. Such an exact positioning is particularly useful from then on  partly if a workstation is held by several fastening devices the should, since the exact engagement of the further fastening before by the fitting bolt directions is guaranteed after closing the first fastening devices. A such a configuration, in the work stations by means of at least two fasteners devices can be attached to the universal table is particularly advantageous if when the work stations are relatively large or when there are large forces at work stations occur. Large vices, parallel collets, Miter cutters, miter saws, lever shears, bending devices or Plate shears called. In these two fastening devices are usually sufficient tion and an additional fitting bolt. For even larger workstations, like at for example a wood lathe, but can also have three or four attachment points directions and / or several fitting bolts can be provided. Are two attachment options directions provided with eccentric curves, it is useful if this are rotated in opposite directions. This makes the lock even firmer and the danger of loosening further decreased.

There are different work stations that must have a great depth, or at which strong forces act in the vertical direction. For such workstations it is useful if the workstations are flat on the table top Have area. Examples of this are vices, drill stands or devices for hammering and straightening sheet metal.

In the universal table according to the invention, the number of fastening devices is and the number of workstations that can be added only by the table size limited. Also for the diversity and purpose of the work station There are no limits. They can be devices for clamping Workpieces or processing aids. However, all types of Machines can be designed as work stations. In this regard, the already referred possibilities mentioned.

Another embodiment is used to prevent accidents. It is provided that in Area of the fasteners below the table top recesses orders are to intervene in the overhangs of the workstations in such a way that the Work stations are held by this when the fasteners  are open. This is particularly useful when workstations are not open lie on the table and have a certain size or weight exhibit. An example are parallel collets, in which the projecting parts are the Guides and the spindle in a recess between the table top and one Intervene. Such a measure should in particular be provided if the universal table is made by people who have not been trained in manual work, such as students or DIY enthusiasts.

A useful development provides that at least one under the table top Hanging rail is arranged, hung in the workstations for storage can be. Such a hanging rail can be T-shaped for a corresponding one Recording the workstations, or it is possible to use two rails as Form brackets that hold the workstations on both sides. Such han rails can be provided for the inclusion of one or more workstations his. A particularly useful embodiment provides that the slopes rail for a large table in the middle of the table below the entire table extends. For a small table, the hanging rail expediently becomes the Side on which work is arranged opposite. That way it is possible to keep different workstations under the table, or, for example for use in school operations, a large number of identical workstations to accommodate a large table.

Shelves can also be arranged under the table top for storage of tools, drawing and cutting documents or other objects.

For setting up the universal table outdoors, for example in workshops or schoolyards, it can be provided that the universal table is made of reinforced concrete and at least half of the fasteners located on the universal table are made of stainless steel.

Fig. 1 shows an embodiment of the universal table 1 according to the invention in a perspective view. The table top 3 of the universal table 1 is equipped on three outer sides 7 with halves 6 of fastening devices 4 , 4 '. The other halves 5 of the fastening devices 4 , 4 ′ are located at work stations 2 . The latter are designed as actuatable halves 5 of the fastening devices 4 , 4 '. The fastening devices can - as already mentioned above - be designed in different ways. If there are fastening devices 4 , 4 'with eccentric curves 8 , 8 ', it is expedient if a pair of a clockwise closable fastening device 4 and a left-handed closable fastening device 4 'are assigned to one another, in the middle between these fastening devices 4 , 4th 'There is a fitting bore 13 for receiving a fitting bolt 12 . In this way, a secure hold of a work station 2 is achieved and it is ensured that after one of the fastening devices 4 or 4 'has been closed, the other fastening device 4 ' or 4 is also in the engaged position. Such an arrangement of fastening devices 4 and 4 'is particularly expedient when work stations are to be fastened on which large forces act. As a game, a vice 16 is drawn in Fig. 1, which is attached to the table top 3 . This work station 2 , designed as a vice, has a side 14 that can be attached to the table top 3 and a surface 15 lying flat on the table top 3 . As a result, the vice 16 is not only securely connected to the table top 3 , but at the same time it has a support surface 15 which absorbs the action of large forces, such as occur during hammering. The closing of the fastening devices 4 , 4 'is carried out by means of a key 10 which can be guided into engagements 11 . These are preferably continuous so that they do not fill with chips, but instead fall through them. Of course, a smaller vice can also be equipped with only one fastening device 4 .

As a further example of a work station 2 , a parallel collet 17 is drawn, which is to be connected to the universal table 1 . For this purpose, are cantilevers 22, are the guides 27 and the spindle inserted into a recess 21 of the universal table 1 in the parallel chuck 17 28th This recess 21 , which is formed by the table top 3 and a spar 32 of the universal table 1 , has the advantage that the work station 2 is held in the recess 21 by its projections 22 even in the non-attached state. This serves occupational safety, especially for untrained people. The actuatable halves 5 of the fastening devices 4 , 4 'are accommodated in the rear clamping jaw 31 of the parallel collet 17 . There are also the interventions 11 for the key to connect the parallel collet 17 to the table 1 . This key sel 10 can be designed such that it also serves to actuate the collet 17 and can be inserted into the key engagement 30 . For this purpose it can be provided that the key 10 has two different sizes, for example a 12 mm hexagon and an 8 mm hexagon on one of the legs with a shoulder.

The parallel collet 17 can run flat on its top with the table top 3 or be slightly higher than the table top 3 . Such a protrusion of approximately 5 mm serves to ensure that the table top 3 is not damaged when machining a workpiece, for example by means of a file or rasp.

The universal table 1 is designed such that it 'has and on each narrow side of the halves 6 of two pairs of fastening devices 4, 4' on its longitudinal side the halves 6 of three pairs of fastening devices 4; 4. Of course, not only those work stations 2 can be added to these halves 6 of the fastening devices 4 , 4 ', which also have two halves 5 of fastening devices 4 , 4 ', but also those which only have one half 5 of a fastening device 4 or 4 ' having.

The design of the universal table 1 is of course only exemplary, it can be built universal tables 1 of any size, which can then have a number of fastening devices 4 , 4 'corresponding to their size.

Under the table top 3 there may be a hanging rail 23 , which is formed from two angles in the example shown in the Darge, in which work stations 2 can be pushed. A vice 16 is shown as an example. This hanging rail 23 can be designed to accommodate a work station 2 short or to accommodate many work stations so that it extends over the entire underside of the table 1 . As a result, many different workstations 2 or many of the same ones can be stored under the table 1 . The latter is particularly advantageous when the universal table 1 is to be used in teaching, and therefore under the table 1 four or more vices 16, or other work stations 2 are accommodated len sol. In the case of a relatively small table 1 , in which work is only carried out on its front side, the hanging rail 23 is expediently arranged in the rear part. In the case of a larger table 1 , on which workstations are arranged all around, the hanging rail 23 is expediently arranged in the middle of the table so that it does not hinder work. Furthermore, shelves 24 can be provided, the z. B. for storing cutting documents, tools or the like.

FIG. 2 shows a clamping pad 33 for a work station 2 , which is designed as described for the vice 16 in FIG. 1. Such Spannunterla conditions 33 are versatile, it can be miter cutters, table clamp ner, drill stand and much more can be arranged. To attach such a clamping pad 33 or a correspondingly designed workstation 2 , it is placed with the surface 15 on the table top 3 and with the side 14 brought to the outside 7 of the table top 3 , a fitting bolt 12 being inserted into a fitting bore 13 (the latter are shown in FIGS. 2a and 2b). In this position, the respective halves 5 and 6 of the fastening devices 4 and 4 'face each other. By inserting the key 10 into the engagement 11 , the fastening devices 4 and 4 'can now be brought into the locking position. The engagement 11 for the key 10 is provided with a bush 54 at the edge of the engagement 11 to protect the table surface. It is preferably a pressed plastic part. The fastening devices 4 , 4 'can be designed differently. Examples of games are shown in FIGS. 2a to 5.

Fig. 2a shows a first embodiment of a fixing device 4, 4 '. A through hole 40 leads to a hexagon socket 55 and from there to the underside of the clamping pad 33 . The hexagon socket 55 is located in a rotatable disc 25 , on which eccentric curves 8 , 8 '(shown in FIGS . 3, 3a and 3b) are arranged for locking. The side view of a Spannunter layer 33 shown in Fig. 2a further shows the arrangement of the fitting bolt 12 , which can be inserted into the fitting hole 13 to attach the clamping pad 33 to the table top 3 .

Fig. 2b shows the same clamping pad in plan view, the rotatable disks 25 of the actuatable halves 5 of the fastening devices 4 and 4 'are shown. The eccentric curves 8 , 8 'are located on these rotatable disks 25 , which are not yet shown here. However, Fig. 2b shows how the Befestigungsvorrich obligations 4 and 4 'can be closed in different directions of rotation 34th

Fig. 3 shows an embodiment of a fastening device 4 in section. The fastening device 4 consists of an actuatable half 5 , which is preferably located at the work station 2 and a half 6 with holding elements 9 and 9 ', which is embedded in the table top 3 . The actuatable half 5 consists of a rotatable disc 25 which carries two eccentric curves 8 and 8 '. These are arranged above and below, that is to say in mirror image, on the rotatable disk 25 . The closing process of the fastening device 4 results from the combination of FIGS . 3, 3a and 3b. In Fig. 3b, the fastening device is provided in the open state, in which the eccentric curves 8 and 8 (only the latter is visible) are out of engagement. If the work station, the table plate 3 brought 2 with its side 14 to the outer side 7, so that the two halves 5 and 6 of tung Befestigungsvorrich 4 facing each other, the fastening device 4 can be closed. For this purpose, the key 10 is inserted through the engagement 11 and the through hole 40 into an inner hexagon 55 and the rotatable disc 25 is moved in the direction of rotation 34 until the holding elements 9 and 9 'are gripped by the eccentric curves 8 and 8 ' and Workstation 2 is pressed by the further rotation on the table top 3 . This closed state is shown in FIG. 3a from above and in section in FIG. 3. It is shown in Fig. 3, where the cut surface for the presen- tation of Fig. 3a runs and in Fig. 3a shows where the cut surface for Fig. 3 runs.

The fastening device 4 is of course only shown by way of example, it can also have only an eccentric curve or another design. It can also be made from solid sheet metal parts instead of solid material.

Fig. 4 shows a second embodiment of a fastening device 6, 6 'with bolt 46th To attach a workstation 2 to a universal table 1 , a bolt 46 (or correspondingly several bolts 46 simultaneously) is inserted into a recess 62 of the universal table 1 and pivoted or shifted in the direction of the double arrow 61 until the bolt 46 rests on a bolt 47 . Then a key 10 is inserted into the hexagon socket 55 and an eccentric 45 , which is mounted in the bolt 46 , is rotated such that the bolt 46 moves from the position shown in broken lines to the position shown in solid lines in the direction of the double arrow 60 . This rotation of the eccentric 45 allows the work station 2 to be firmly clamped to the universal table 1 . The fastening device 6 , 6 'is opened in the reverse manner.

Fig. 5 shows a third embodiment of a fastening device 6, 6 'with a locking pin 48. This is located at a work station 2 and is rotatably mounted there (arrow 64 ). For the rotation 64 , the locking pin 48 is equipped with a hexagon 63 . The locking pin 48 has a transverse holding rod 48 which is expediently adjustable in the direction of arrow 65 by means of a threaded rod 53 . This serves to adjust the holding rod 48 and thus to set the clamping force. Half 6 of the fastening device, which is located on the side of the university folding table 1 , has a holding cam 50 with an opening 54 , two inclined planes 51 and two holding surfaces 52 , which are expediently delimited by stops 67 . To attach the workstation 2 , the locking pin 48 (possibly correspondingly a plurality of locking pins 48 ) is inserted into the opening 54 of the hal tenocke 50 (arrow 66 ) and then rotated (arrow 64 ) such that both ends of the holding rod 49 are each on an inclined plane 51st get to a holding surface 52 . In this position, the locking pin 48 is drawn with a dash-dotted line with one end of its holding rod 49 . By closing the fastening device 4 , 4 ', the work station 2 is firmly clamped to the universal table 1 . The stops 67 ensure that the locking pin 48 with the holding rod 49 is not rotated beyond the holding surfaces 51 .

These fastening devices 4 , 4 'are of course only Ausführungsbei games that were considered to be particularly advantageous, further execution possibilities are conceivable.

Fig. 6 is designed as a support for a sign board 18 working station 2. This work station 2 can be attached to the table top 3 in the manner described and has a hinge 41 in the region of its upper side to which the drawing board 18 is fastened, which can be set up obliquely on the table 3 by means of a support 43 . For this purpose, the support 43 is connected to the drawing board 18 by means of a further hinge 42 . The support 43 is held in its position either by a limited opening of the further hinge 42 or by some other measure. For example, it is possible to rubberize the support 43 at the end of its support. The work station 2 can additionally have a pencil rest 35 .

Fig. 7 shows a support 19 formed as painting materials for working station 2. For example, a removable brush holder 36 and a removable water or paint mixing container 37 can be arranged on this holder 19 . The brush holder 36 is spiral-shaped, brushes 57 are clamped. Corresponding other elements can be provided for other purposes, for example for oil paints.

FIG. 8 and FIG. 8 show a Laubsägebrett formed as 20 working station 2. The Figure 8a shows 8b. A side view and Fig. Is a plan view. This than Laubsä gebrett 20 trained workstation 2 is an example of how the fastener in the manner already described, but provided with only one fastening device 4 is accepted. Only the actuatable half 5 of the Befestigungsvor direction 4 is shown , which is located at the workstation 2 .

Fig. 9 shows a clamping base 26 for a height adjustable work station 2. This can also have one or more fastening devices 4 . To complete the workstation 2 , another element 68 is inserted into a guide 44 and locked at the desired height. An elongated hole 59 in the further element 68 of the work station 2 serves this purpose. Through the slot 59 engages a lever 59 therethrough, which is mounted by means of a thread in the clamping pad 26 and the locking of the other member 68 and hence the working station 2 is used.
