Brief Patent Description - Full Patent Description - Patent Application Claims
[0001] The invention relates to a work table. It relates in particular to a work table for the workshop area. [0002] Work tables in the workshop area, but also in all other areas in which work tables are used, are utilized on the one hand for receiving the tool and/or the working means, and on the other hand for receiving and/or setting down the material to be worked. In the workshop area, the tools are frequently securely mounted on the worktop of the work table. However, the mounting of tools on the work table inevitably leads to a reduction in the surface of the work table that is then available for the materials to be worked. [0003] Moreover, a plurality of different tools, for example woodworking, metalworking or other machining tools or equipment, are required in particular in workshops, so that an appropriately large working surface is required on the one hand for the tools alone, and on the other hand for the materials to be worked. The working surface is not usually adequate for this reason. [0004] A solution to this problem often involves the use of smaller, and thus more mobile variants of the individual tools. Tools of this kind are subject to performance limitations, however, so that their use is not actually possible in the professional area. [0005] Previously disclosed by DE 41 06 073 C2 is a work table, which exhibits a recess in a worktop, in which recess different tools arranged on a worktop segment can be mounted or added by means of a rotating mechanism. Although a much more favorable utilization of the surface of a work table is achieved in this way, the associated cost is comparatively high, namely when the envisaged machine magazine is embodied as a rotary magazine. Consideration must also be given to the fact that only a single working machine can be brought into the plane of the worktop of the work table in each case. [0006] A further solution involves mounting only the tool that is required in each case on the work table. The replacement of a tool in this case is time-consuming, however, so that a dedicated work table is required as a general rule for each tool. [0007] The object of the invention is to overcome the disadvantages associated with the prior art. The intention in particular is to propose a work table which permits the use of two or more tools on a small work surface, compared with the prior art. [0008] This object is achieved by the characterizing features of claim 1. Appropriate embodiments can be appreciated from the characterizing features of claims 2 to 12. [0009] A work table with a worktop for mounting tools is proposed in accordance with the invention, wherein [0010] the worktop exhibits at least one or a plurality of recesses, and arranged in each case in each recess is a worktop segment that is rotatably mounted in the worktop about an axis of rotation running parallel with the upper surface of the worktop; [0011] the work table comprises devices for locking the worktop segment in the worktop; [0012] the worktop segment in the area of the axis of rotation is mounted in each case in two guides embodied on the work table; and [0013] the worktop segment is capable of displacement alone or with the axis of rotation along the guides parallel with the upper surface of the worktop. [0014] In a first embodiment of the work table in accordance with the invention, in the locked state the upper surface of the worktop segment and the upper surface of the worktop together form a single plane. In this embodiment, the axis of rotation is arranged in the plane of the worktop. [0015] The work table in accordance with the invention thus makes it possible for a (first) tool, which is attached to the upper surface of the worktop segment, to be moved by causing it to rotate through 180.degree. about the axis of rotation to a position under the work table. [0016] Through this rotating movement, the previous upper surface of the worktop segment becomes the under surface, and vice versa. The external surface of the worktop segment, which is then rotated upwards, can then be utilized depending on the requirements of the user. If no addition tool is mounted on this external surface, it is available as an unobstructed work surface. By further rotation of the worktop segment, the (first) tool can be moved upwards, as a result of which it is once again ready for use. [0017] The "folding down" of tools in this way thus permits a clearly improved utilization of the space available. If, for example, a clear work surface is required to enable constructional drawings to be laid out, all of the tools can be rotated downwards, wherein the previous, clear under surfaces of the worktop segments are rotated upwards. The tools are removed from the work surface of the work table in this way, so that the entire surface of the work table can now be used freely. [0018] The work table in accordance with the invention permits significantly better utilization of the space available. This also offers advantages in conjunction with the installation of extraction systems, which, because of the more compact arrangement of the tools, only need to exhibit a small effective area. Furthermore, the work table in accordance with the invention is capable, if the table legs are of folding execution, of being transported more easily in vehicles, given that on-site use is otherwise only possible with tools that are capable of being transported separately. [0019] In the first embodiment, the devices for locking the worktop segment in the worktop are preferably executed as locking levers, wherein [0020] at least two locking levers are provided for every worktop segment, and [0021] every locking lever exhibits a first position and a second position, in which first position the worktop segment is capable of rotating in the work table (unlocked state of the worktop segment), and in which second position the worktop segment is locked in the worktop (locked state of the worktop segment). [0022] A first edge of the worktop segment in the locked state is appropriately part of an outer edge of the worktop. In this case, the recesses are executed with a U-shaped form in the worktop, so that larger tools, which are attached to the worktop segment, can also readily be rotated upwards or downwards. This would not necessarily be the case for square or rectangular recesses, i.e. recesses that are arranged in the worktop without a common outer edge. [0023] The first edge of the worktop segment preferably exhibits a first groove, wherein the second edge of the worktop segment lying opposite this first edge exhibits a second groove, and the worktop exhibits a web, which is complementary to the first and second grooves. The web in this case is executed on the edge of the worktop, which in the locked state of the worktop segment is adjacent to the second edge of the worktop segment, and in the locked state engages in the second groove, whereas in the unlocked state the engagement between the web and the second groove is released. [0024] The axis of rotation must not necessarily be executed as a transcurrent axis. On the contrary, the two ends of the axis of rotation are preferably executed as bolts, which on the one hand are anchored in the worktop segment and on the other hand are supported in the guides. [0025] In a second embodiment of the present invention, the upper surface of the worktop segment in the locked state is arranged parallel with the upper surface of the worktop, wherein [0026] the worktop segment is present either in a first plane or in a second plane; [0027] the second plane runs below the first plane in relation to the height of the work table; [0028] the upper surface of the worktop segment and the upper surface of the worktop form a plane if the worktop segment is present in the first plane; and [0029] the upper surface of the worktop segment is present below the upper surface of the worktop in relation to the height of the work table if the worktop segment is present in the second plane. [0030] In this embodiment, the axis of rotation is arranged beneath the first plane of the worktop. The guides, in which the axis of rotation is mounted, are preferably executed as so-called indexable blocks, which are arranged on the under surface of the worktop or on the work table in the area of the stand elements underneath the worktop. [0031] The distance between the first plane and the second plane is preferably variable. This is preferably achieved by displacing the axis of rotation running parallel with the surface of the worktop vertically in relation to the worktop. The indexable blocks, in which the guides are present, are preferably displaced upwards or downwards in addition, wherein the indexable blocks can be moved upwards or downwards for this purpose, for example, along a screw thread. [0032] This second embodiment has the advantage that the worktop segment is capable of being locked at different heights. Larger items of equipment, for example, which would otherwise require to be mounted on a lower table, can also be positioned readily in this way on the work table in accordance with the invention. [0033] Similarly, as in the first embodiment, the devices for locking the worktop segment in the worktop are embodied as locking levers, wherein, however at least four locking levers are provided for each worktop segment; [0034] two first locking levers are arranged in the first plane, and two second locking levers are arranged in the second plane; [0035] each working lever exhibits a first position and a second position, in which first position the worktop segment is capable of rotating in the work table (unlocked state of the worktop segment), and in which second position the worktop segment is capable of being locked to the work table (locked state of the worktop segment); and [0036] the worktop segment is either locked in the first plane by means of the first locking lever, or is locked in the second plane by means of the second locking lever. [0037] The second locking levers are appropriately secured to the work table by means of a first securing element. These first securing elements and with them the second locking levers should be capable of being folded under the table, wherein they can be unfolded if they are required for the purpose of locking the worktop segment in the second plane.
