ARRANGEMENT IN WORKING PLACES

Abstract: This invention relates to an arrangement in working places, each provided with at least one table, two adjacent tables being positioned in an angular distance from each other with an angle which is less than or equal with 180 DEG , and a service unit for wires, tubes and similar for service functions being arranged at the area for a point of intersection of the longitudinal centre lines of the two tables. According to the invention the service unit (9) has an essentially vertical extension and are the two tables (1, 2; 3, 4; 5, 6; 7, 8; 17A, B; 17B, C; 17C, D; 17D, A) positioned at an angular distance from each other moveably fastened on a unit (13A; 13B; 13C; 13D; 19) of a floor stand. The tables are moveable in an essentially vertical direction in relation to each other and in relation to the service unit.

Description: Arrangement in working places This invention relates to an arrangement in work¬ ing places, each provided with at least one table, two adjacent tables being positioned at an angular distance from each other with an angle which is less than or equal with 180°, and a service unit for wires, tubes and similar for service functions being arranged at the area for a point of intersection of the longitudinal centre lines of the two tables. A device having essentially the construction as has been mentioned above is previously known by German Offenlegungsschrift 2.261.676. According to this one there is a service unit from which extend four tables, which are positioned with an angular distance to each other of 90°. Therewith the four tables are rigidly fastened to the service unit. Thus, the tables can not be raised or lowered in relation to each other or in relation to the service unit. Moreover, the known system is inflexible, since the system cannot simply be changed to an alternative of two tables and three tables, respectively, with regard to the locking of the tables to the service unit. This invention intends to remove the drawbacks with known technique and offer an arrangement which is very flexible regarding the construction and which is so arranged that different kind of working moments can be brought about whether one is standing or sitting at the working tables. This has been made possible by an arrangement of the kind mentioned by way of introduc¬ tion which is characterized in that the service unit has a verticle extension, that the two ta ' bles posi¬ tioned at an angular distance from each other are move- ably fastened to at least one unit of a floor stand, and that the tables are moveable in vertical direction in relation to each other and the service unit. Due to that fact the arrangement becomes very space-saving and can be built up according to a module system with several units of a floor stand positioned adjacent to each other. Furthermore, different types of working moments can be brought about on the working tables by the movement possibilities of these one in relation to each other and in relation to the service unit. More¬ over, due to the vertical extension of the service unit not only wires and tubes for the service functions but also devices for for instance dust separation and smoke exhaustion can be included in this one. According to a further developed invention each working place comprises two tables positioned at an angular distance from each other, the unit of the floor stand being common for the two tables. Therewith is further one table of one working place positioned close to and essentially parallel with the second table of the second working place. According to another embodiment of the invention, which is still more developed, the table edges directed towards each other of the two tables positioned essen¬ tially parallel and close to each other are provided with an essentially vertical wall, which is so designed that independently of the height position of one table in relation to the second one the wall of the one table cannot pass the wall of the second one. This means that the risk of squeezing damages can be reduced. The risk of squeezing damages during the movement of the tables in relation to each other and in relation to the ser- vice unit can be further reduced if the distance be¬ tween on one hand the two walls at the table tops and on the other hand between the table edges and the ver¬ tical surface of the service unit either is less than or larger than the thickness of the hand/fingers. How- ever, it is to prefer that the distance mentioned above is less than the thickness of the hand/fingers, because due to that fact the whole system becomes more compact and requires less spaces . Other essential features will appear from the fol¬ lowing description of the invention with reference to the accompanying drawings, in which Fig. 1 shows a principle sketch of a first embodiment of the invention when having four working places, Fi . 2 shows a per¬ spective picture of an embodiment of the arrangement when having four working places, Fi . 3 shows a floor stand with a centre plate for the four working places, and Fig. 4 shows a principle sketch of a second embodi¬ ment of the invention. Referring to Fig. 1 is shown there a principle sketch of the invention, four working places A-D with eight working tables 1-8 being arranged. The working places A-D are so arranged that the person sitting at the working place A easily can reach the two working tables 1, 2, while the person sitting at the working place B easily can reach the working tables 3, 4 and so on. The working tables according to this embodiment are so arranged that the longitudinal centre line of one working table 1, 3, 5, 7 of one working place inter¬ sects the longitudinal centre line of the second work¬ ing table 2, 4, 6, 8 of the same working place under a right angle. Furthermore, the working tables are so positioned that the second working table 2, 4, 6, 8 of each working place is positioned adjacent to the first working table 3, 5, 7, 1 of each working place. Taken together this results in that the invention has very low requirements regarding the space. In the centre of the four working places a service unit 9 is arranged which has a vertical extension and an essentially square cross-section. Therewith the tables 1-8 are so arranged in relation to the service unit that respec- tive point edge of the service unit is directed to the dividing line between the tables 2, 3; 4, 5; 6, 7; 8, 1. This fact also contributes to the system becoming compact and space-saving. Of course the service unit can have another cross-section, for instance circular. Furthermore, the service unit can have another position 5 in relation to the different working tables. Thus, respective point edge of the service unit can be di¬ rected towards the dividing line between the tables 1, 2; 3, 4; 5, 6; 7, 8. In Fig. 2 the arrangement is shown more closely. 0 As appears from the figure each working table has a working leaf 1A - 8A and can be provided with equipment for different purposes. Each working table is raisable and lowerable by means of a lifting device which is preferably electrically operated. On the back of each 5 working table there is fastened a plane, essentially vertical leaf Cthe leaf 6B of the table 6 and the leaf 7B of the adjacent table 7 are indicated in Fig. 2). Therewith, the two leaves 6B and 7B and corresponding leaves of the other tables are so close to each other V that when one table of one working place is raised or lowered in relation, to the adjacent table of the ad¬ jacent working place there is no risk of squeezing damages on hands or other things. The two leaves 6B, 7B are so arranged that when the tables 6A, 7A are in a 55 maximum distance from each other in the vertical direc¬ tion they cannot pass each other. This means that the lower horizontal edge of the upper leaf shall not be higher than the upper horizontal edge of the lower leaf . 0 In the centre of the eight working tables there is a service unit 9 as has been mentioned previously. This unit according to this embodiment has four essentially vertical sidewalls comprising plane leaves 10A-10D of which two IOC, 10D are shown in Fig. 2. These leaves 5 have such a length that they extend down to a floor stand not shown in this figure on which the working tables rest. Instead of resting on the floor stand the leaves 10A-10D can rest on a base of varying height which in its turn rests on the floor stand. The four side leaves according to this embodiment form a square cross-section and has such a fit in relation to the bevelled inner edges of the leaves 1A-8A of the working tables that neither there is any squeezing risk during the movement up or down of the working tables in rela¬ tion to the service unit 9. This risk of squeezing damages is further reduced by the fact that the inner edges of the essentially horizontal leaves 1A-8A of the working tables extend essentially parallel with the wall of the service unit 9. When raising and lowering respective table in re- lation to another table and in relation to the service unit the movement accordingly becomes essentially ver¬ tical and essentially parallel with the walls of the service unit. The service unit 9 is intended to enclose appa- ratuses, electrical cables, other wires, water tubes, water seal and tubes (indicated by 11) for exhaustion of dust and particles formed during the work. The ser¬ vice unit can further enclose a device for separation of dust which is sucked away from the working table and/or a device for exhaustion of smoke. From the figures 1 and 2 appears that the working places A, B, C, D are arranged according to a module system which means that the invention relates to not only an arrangement having four working places but also two or three working places . In Fig. 3 there is shown a floor stand 13 for the four working places A, B, C, D. This floor stand is also built up according to a module system having 1-4 units 13A, B, C, D. Each unit according to this embodi- ment comprises two right-angled beams intended to be positioned on the floor and intended to be fastened to the right-angled beams of an adjacent unit in a suit¬ able way if several working places are desired. The two beams of the unit 13A-13D at their outer ends have a pillar 14A, 15A-14D, 15D which is directed upwards and 5 intended to be a guide for a stand on which each work¬ ing table is fastened. Thus, each stand of the working table comprises a pipe intended to slide on the pillar 14A, 15A-14D, 15D when operating the lifting device of the working table. Each unit 13A-13D of the floor stand 10 is intended to carry two working tables. Therewith the unit 13A is intended to carry the tables 1, 2, the unit 13B the tables 3, 4, the unit 13C the tables 5, 6 and the unit 13D the tables 7, 8. According to this embodiment the pillars have been 1.5 placed at the very end of the right-angled beams . Of course the pillars can be positioned in another place, for instance at the middle of the beams . Due to the fact that the floor stand is so de¬ signed as is shown in the drawings, i.e. that the two 20 right-angled, hollow beams of each floor stand have their common point directed towards the centre of the working places, there is formed a large and open space under the two tables at each working place, whereby a good space for the legs is created and a good cleaning 25 is made possible. Moreover, the system becomes very compact and space-saving. In Fig. 3 there is also shown a centre plate 16 which is intended to rest against the inner portions of the right-angled beams. On this centre plate rest the 30 plane leaves 10A-10D which comprise the outer limita¬ tion walls of the service unit 9. The embodiment according to Figs. 1 , 2 is princi¬ pally intended to be used in laboratories and offices. In Fig. 4 there is shown a principle sketch of a 3.5 second embodiment of the invention, intended to be used principally in industrial halls. This embodiment only has four tables 17A-17D in contrast to the former embodiment which has eight tables. It could be said that the pair 2, 3; 4, 5; 6, 7; 8,1 of tables in Fig. 3 has been put together to one table. Also in this case the tables are movable in an essentially vertical direction in relation to each other and in relation to the service unit 18. Therewith the portions of the tables 17A-D which are directed towards the service unit are so bevelled that the edge of the portions extends essentially parallel with the wall of the service unit 18. Also according to this embodiment the service unit has an essentially square cross-section. Therewith the service unit and the tables are preferably so arranged in relation to each other that respective point edge of the service unit is directed towards the longitudinal centre line of the tables 17A-D. In the figure the floor stand has been indicated by the numeral 19. The floor stand can be designed in the same way as is shown in Fig. 3. Alternatively, the pair 13A, B; 13B, C; 13C, D; 13D, A of beams in Fig. 3 can be put together to one beam and the pair 14A, 15B; 14B, 15C; 14C, 15D; 14D, 15A of pillars can be put to¬ gether to one pillar. According to another alternative embodiment the four right-angled beam pairs 13A, B, C, D according to Fig. 3 are arranged as a floor stand for an arrangement according to Fig. 4. Therewith the pair 14A, 15B; 14B, 15C; 14C, 15D; 14D, 15A of pillars is replaced by a single pillar which is positioned between the beams 13A, 13B; 13B, 13C; 13C, 13D; 13D, 13A of the floor stand and preferably at the very end of these ones. The invention is of course not limited to the men¬ tioned embodiment with an arrangement for four working places. Thus, the invention can be modified so that two or three working places are created, the module system being designed in another way. According to the later system each module, i.e. each working place takes up 120° of a circle, while two modules takes up 240° and three modules 360°. This means that the floor beams of the stand in this case form an angle of 120° with each other, and that also the two centre lines of the two working tables constituting a working place form an angle of 120° with each other. The great advantages with the new arrangement is that it: 1. Makes a construction of two or several working places on basis of one basic equipment possible. 2. Makes an increased bench area in an existing space possible. Ξ 3. Makes improved adaptation possibilities between working table and man possible. 4. Makes a cheaper pipe and wire installation possible. 5. Makes a large and open space under the two " tables at each working place possible. 6. Makes a vertical movement of the tables in re¬ lation to each other and in relation to the service unit possible. 7." Prevents squeezing damages on hands and fingers of the person working at the tables .
