Description:
BACKGROUND OF THE INVENTION 
     The invention relates to a device for the releasable securing of containers for the sorted storage of tools and/or tool parts, on a base of, in particular, a drawer, the base itself or an underlay arranged between the container and the base possessing securing elements or recesses for fixing the container, and the container base possessing counter-elements for these securing elements or recesses. 
     In many cases in everyday life and in industrial sectors, articles are used which are sorted. Although reference is primarily made below to tools and/or tool parts, the present invention is not intended to be restricted thereto. It applies to a very large number of articles. 
     FR-A 2 254 193 and U.S. Pat. No. 5,556,180 have disclosed, for example, card-index boxes in which index cards or even files can be stacked obliquely. The same also applies to U.S. Pat. No. 1,900,148. 
     For tools, tool chests are known, such as are described, for example, inter alia in U.S. Pat. No. 4,285,556. These tool chests possess pegboards, into the holes of which hooks can be inserted. These hooks then serve to retain the corresponding tools. 
     If, for example, articles are laid in drawers, those articles move, often to an undesirable extent, when the drawers and opened and closed. This applies in particular to the abovementioned tools, such as drills, milling cutters, etc, which are sorted by size or other particular parameters. Thus, known tool chests already include containers with depressions or the like in which these tools lie. In most cases, however, these tool chests are arranged far from a machine in which these tools are used. In other words, the user firstly locates the tool in the tool chest and then fits that tool to the machine. If he discovers at the machine, however, that the tool is not the right tool, he must return to the tool chest and fetch, for example, a tool of a different diameter. This takes time and is undesirable. 
     U.S. Pat. No. 5,211,458 has in turn disclosed a chest in which two drawers are provided. Inserted into the upper drawer is an underlay from which obliquely positioned strips project downward, on which, for example, a container can be placed which in turn possesses channels on the base side. The container serves, for example, to receive files. 
     U.S. Pat. No. 4,709,970 has disclosed an arrangement in which measuring instruments are secured on a perforated base. The securing is provided by angular plug-in frames. 
     The object of the present invention is to provide a device of the type referred to above with which the containers can be kept cleanly sorted and do not become mixed up, and in which the user can take a plurality of required containers with him. 
     SUMMARY OF THE INVENTION 
     The foregoing object is achieved in that pegs, as securing elements, or the recesses are arranged symmetrically and at a uniform distance apart on the base or underlay, and in that either projections projecting downwards from the container base are inserted between the pegs or into the recesses or recesses are molded into the container base, into which the pegs engage. 
     This means that the container no longer slides backwards and forwards on the base of, for example, a drawer, thus creating the risk that containers will become mixed up. In the simplest example of embodiment, the elements of the base or underlay can also engage into one another for securing purposes. Thus, a part could be cut off from the underlay and adhesively bonded to a container, the elements projecting downwards from the container. The container is then placed on the underlay, the elements engaging into one another. This is designed, in particular, for a pocket calculator, a gauge block or a weight box. 
     The containers possess individual depressions or compartments which are formed, in each case, in accordance with the design of the article. If, for example, drills are stored, the container should consist of an integral injection molding in which elongate depressions with rounded-off depression walls are molded. This also greatly facilitates the removal of the drill, which can be pushed out of the depression with one finger. 
     An essential part of the present invention is the design of the base or of the abovementioned underlay. For example, this underlay may be a plate-shaped element which is laid in, for example, a drawer of a tool chest. The disadvantage here is that drawers of tool chests are not standardized and may be of different sizes, so that often one part of the drawer base is not covered by the plate-shaped element. For this reason, in a preferred example of embodiment of the present invention, a flexible material, preferably capable of being rolled up, is used for the underlay. The preferable material here is a plastic, which can be rolled up to form a roll. The user then merely needs to unroll a section from the roll to suit the size of the drawer and cut it off, so that he can line the drawer completely with the underlay, as is preferable. 
     As a connecting element, many designs are suitable. In the simple example of embodiment, projections are provided on the underlay which interact with corresponding container walls and/or recesses and/or projections in or on the container or the container base. The projections of the underlay may be LEGO-type cylindrical plugs on which or between which the container is laid. 
     Conversely, however, it is also possible to form recesses in the underlay into which downward projections from the container base then engage. For example, these projections may be spherical elements which then, in the position of use, rest in a corresponding cup-shaped depression. 
     In a preferred example of embodiment, annular projections project downward from the container base and, when the container is placed on the underlay, engage between four pegs. The actual mounting of the container on the underlay is provided, however, by peripheral side walls, so that the projections on the container base may actually be dispensed with. The side walls enclose a receiving window which is so designed that it extends tangentially around corresponding pegs on the underlay. 
     Should annular projections exist between the side walls of the container, these preferably do not extend beyond the lower marginal edge of the side walls, so that the container stands on the outer side walls even if the underlay is removed. 
     The advantage of this design is that not merely an article from the container but the whole container can be removed from the drawer with a large number of sorted tools and transported to the machine. The selection is then made at the machine to determine which tool is specifically required. Considerable movement is saved by this. 
     With many tools, the containers do not need to be very thick in shape, so that a plurality of containers can also be stacked one above the other in a drawer. In order that these should likewise be secured in the drawer, the surface of the container will again be provided with projections or recesses into which downward projections from the container base or recesses molded into the container base then engage. 
     In a preferred example of embodiment of the invention, the projections are distributed over the marginal edges of the containers in such a way that any desired variant of stackability is possible. Many conceivable possibilities exist for this, and the present invention is intended to, encompass them. Furthermore, the projections on the marginal edges of the containers preferably form a different system from the securing system of the underlay or the base. 
     The overall arrangement of the projections and recesses is selected so that the containers can be placed in a drawer not only in one alignment but also in the alignment rotated through 90° relative thereto. Accordingly, the projections and recesses are symmetrically arranged. This also applies, naturally, to the projections or recesses on the surface or marginal edge of each container. 
     Furthermore, the possibility has also been considered of arranging the projections and recesses in particular configurations so that only containers from a particular manufacturer can be used. The same also applies to a diameter of the projections and recesses and to their height or depth. Also, projections could be used that are larger in the lower region or the recesses could be made larger so that they can be more easily located by the projections when the containers are inserted. 
     In some cases, it is also important for the underlay to be adapted to a drawer size or the like. In these cases, it may become necessary for a section to be cut off from the underlay and, possibly, placed at another point in the drawer. A special cutting aid is provided for this cutting-off operation, which greatly facilitates it in a simple manner. In the preferred example of embodiment, the cutting aid consists of a strip whose width approximately corresponds to the distance apart of the pegs on the underlay. The strip contains a slit into which a cutting tool can be inserted. 
     The strip can now be passed between the pegs, together with the cutting tool, so that the cutting tool remains in line. The section to be cut off is then broken, for example, over the edge of a table. 
     In a preferred example of embodiment, the cutting aid is also simultaneously designed as a template for matching a connection piece to the underlay. The pegs of the connecting piece should be aligned with the pegs of the underlay so that precise positioning of the containers can be achieved. 
     Also provided on the strip for this purpose is a cover strip in which marginal depressions are formed which maintain a distance apart from one another corresponding to the distance between the pegs on the underlay. 
     In order to enable this cutting aid and template to be usable for both functions, the strip of the cutting aid should possess a height at least corresponding to the height of the pegs on the underlay. If the cutting aid is then used as a cutting aid, the cover strip passes over the pegs. If the cutting aid is used as a template, it merely needs to be twisted so that the pegs engage into the depressions. 
     For some examples of application, it has proven advisable to form the container from a plurality of parts so that its length is matched to an article to be received. Therefore, for example, the container consists of two end pieces between which one middle piece is provided. This middle piece is matched to the length of the article. A plurality of middle pieces may also be provided. 
     To identify the inserted articles, an indicator should preferably be assigned to the container. This indicator can also display the state of wear of the inserted articles, as is described for example in DE 296 02 136 U1. 
     In a simple example of embodiment, a plate has hook-shaped extensions whereby it is hooked into an upper marginal edge of the side wall of the container. In order to prevent the plate being lost, these hook-shaped projections should possess barbs. If the plate is to be removed or replaced, it is merely necessary to lift the plate so that a predetermined breaking point, provided between the plate and the hook-shaped extension, breaks.

     DETAILED DESCRIPTION 
     According to FIG. 1, a tool chest  1  possesses a housing  2  in which a plurality of drawers  3 . 1  to  3 . 5  are removably arranged. A corresponding drawer  3  is shown in detail in FIG.  2 . 
     The drawer  3  possesses a front wall  4 , a rear wall  5  and two side walls  6 . 1  and  6 . 2 . A handle  7  is arranged on the front wall  4 . Furthermore, the front wall  4 , rear wall  5  and side walls  6 . 1  and  6 . 2  enclose a base  8 . 
     On the base  8  lies an underlay  9  which, according to FIG. 2, is of plate-shaped design. However, it is also within the scope of the invention for the underlay  9  to be capable of being cut off from an underlay roll  10 , as is shown in FIG.  3 . It is thus possible to adapt the underlay  9  to the outline of the base  8 . 
     According to the invention, projections  11  rise from the underlay  9  and may be of any desired geometrical shape. Preferably, they are designed as cylindrical plugs or pegs. It is also conceivable that, instead of or in addition to the projections  11 , recesses are formed in the underlay  9  which serve the same purpose. 
     Containers  12  for receiving articles, especially tools, are inserted into the drawer  3 . FIG. 2 shows four such containers,  12 . 1  to  12 . 4 . Each container possesses compartments  13 , into which the corresponding tools or other articles can be inserted. FIG. 2 shows that these containers  12 . 1  to  12 . 4  may also be of different sizes. Preferably, however, they are so designed that they can be distributed symmetrically in the drawer  3 . 
     According to FIG. 5, each container  12  possesses recesses  15  on its container base  14 , a large number of such recesses being shown according to FIG.  5 . It is self-explanatory that far fewer recesses are also sufficient, provided that the distribution is symmetrical. Instead of the recesses  15 , which interact with the projections  11 , projections could also project downward from the container base  14  and engage into corresponding recesses in the underlay  9 . 
     On its surface also, which according to FIG. 4 is designed as marginal edge  16 , the container  12  possesses projections  17  which can interact with corresponding recesses  15  in the container base  14  of another container. Here again, corresponding recesses may be provided instead of the projections  17 , into which recess corresponding projections projecting downwards from the container base  14  can then engage. 
     Instead of the projections and recesses, the corresponding connection between container and underlay could also be provided by magnets. 
     The mode of functioning of the present invention is as follows: 
     First, an underlay  9  is cut off from an underlay roll  10  and fits into a drawer  3 . A desired number of containers  12  is then placed in this drawer  3  on the underlay  9 , the projections  11  of the underlay  9  engaging into the corresponding recesses in the container base  14 . As a result, the container  12  is secured against sliding in the drawer  3 . 
     As soon as the drawer  3  is essentially filled with containers  12 , a second layer of containers may also be stacked on the first layer, and here again corresponding projections  17  projecting upward from the surface of the containers  12  engage into corresponding recesses  15  of the overlying container  12 . 
     If, for example, a particular type of tool is desired, that container which contains these tools, though of different sizes, can be removed from the drawer  3  and brought to the machine. This has the advantage that the full selection of desired tools of a particular type is available at the machine, so that no attention needs to be paid to the size of this tool when searching in the drawer. 
     In a preferred example of embodiment of the invention according to FIGS. 6 to  9 , the underlay  9  is of plate-shape design. From it, the cylindrical pegs  11  project upward at regular distances apart, each set of four pegs forming a free space to receive a ring  18  projecting from the container base  14 . 1 . This container base  14 . 1  is part of a container depression  20  which is connected via reinforcing webs  21  to side walls  19 . 1  to  19 . 4 . 
     The broken lines in FIG. 6 show how the container  12  rests on the underlay  9 . It can be seen that each of the rings  18  is seated between four pegs  11 . It can also be seen that the side walls  19 . 1  to  19 . 4  extend around a plurality of pegs  11 , so that the container  12  is retained by the interaction of rings  18  and the side walls  19 . 1  to  19 . 4  with the pegs  11 . 
     FIG. 8 shows that the rings  18  do not project above the plane of the lower marginal edges  22  of the side walls  19 . 1  to  19 . 4 , so that the container rests on these lower marginal edges  22 . As a result, the stability of the container  12  is greatly improved. 
     The large intervening spaces between the pegs  11 , which can be seen in FIG. 6, additionally permit easy cleaning of the underlay  9 . Furthermore, the pegs  11  are preferably produced by deep drawing, the underlay  9  in this case, which is likewise preferred, being produced from plastic. 
     The arrangement of the rings  18  in the position of use between pegs  11  also has the advantage that the rings  18  need not be arranged too close to the side walls  19 . 1  to  19 . 4 , which in turn has advantages as regards stability. 
     FIGS. 8 and 9 show crenellation-like projections on the marginal edges  16  of the container  12 . 5 . Corner crenellations  23  are provided in the corner regions, a pair of crenellations  24 . 1 / 24 . 2  extending between two corner crenellations  23 . In this case, a distance a 1  between the crenellations  24 . 1  and  24 . 2  of a pair of crenellations should be smaller than a distance a 2  between the pair of crenellations  24 . 1 / 24 . 2  and a corner crenellation. 
     FIG. 10 shows that four different containers  12 . 6  to  12 . 9  can be stacked one on top of the other in this manner, the contents of the lower container in each case remaining identifiable. From the symmetrical arrangements shown in FIG. 10, it could be seen that, for example, the smallest container  12 . 6  could also be placed on the container  12 . 8  in addition to the container  12 . 7 , but that the possibility also exists of arranging a second container  12 . 6  on the container  12 . 7  or on the container  12 . 8 . Similarly, a second container with the dimensions of the container  12 . 7  could also be placed on the container  12 . 6 . Furthermore, a further container  12 . 7 , following the container  12 . 8 , could be placed on the container  12 . 9 , or two containers  12 . 6  are placed on the container  12 . 9  and then follow the container  12 . 8 . The arrangement of the crenellations permits these widely varying possibilities. 
     As mentioned above, the underlay  9  should be adapted, for example, to a drawer. It is therefore necessary, in many enforced cases, for the underlay  9  to be cut to size. A very simply designed cutting aid  25  is provided for this purpose. This consists of a strip  26  having a width b which corresponds to a distance a between two pegs  11 . As a result of this design, the strip  26  can be pushed between a row of pegs  11 , as is indicated by the arrow x. 
     A slit  27  is formed in the strip  26 , into which slit, for example, a knife can be inserted. The knife is thus guided by the strip  26  and passes in a straight line between the pegs  11 . 
     After the underlay  9  has been scored with the knife, the strip to be cut off is broken off from the underlay  9 . 
     In a preferred example of embodiment of the invention according to FIGS. 12 to  14 , a cutting aid  25 . 1  is simultaneously also designed as a template when sizing a strip of an underlay. For this purpose, a cover strip  28  is placed on the strip  26  and possesses marginal centering depressions  29 . 1  to  29 . 4  whose distance apart corresponds to the distance a between the pegs  11 . 
     If an additional underlay strip is now placed on an underlay  9  to fill out, for example, a drawer, the connecting point between underlay and additional strip can be bridged by the cutting aid  25 , as is indicated in FIG.  13 . In this case, the corresponding pegs  11  engage into the centering depressions  29 . 1  to  29 . 3 . The actual securing of underlay  9  and connecting strip is preferably provided by adhesive sticks or the like. 
     Should the cutting aid  25 . 1  be subsequently used again as an actual cutting aid, the cutting aid  25 . 1  is twisted, the height of the strip  26  being selected so that the cover strip  28  passes over the pegs  11 . 
     For long articles, such as, for example, rods, shafts, drills or the like, it has proven advisable to develop a container  12 . 10  which consists of at least three parts. Two end pieces  30 . 1  and  30 . 2 , which are open on one side, receive a middle piece  31  between them which is open on both sides. 
     Furthermore, as many middle pieces  31  as desired or a middle piece  31  of a specific length may be provided between the two end pieces  30 . 1  and  30 . 2 . 
     DE 296 02 136.9 has disclosed a wear indicator relating to a tool located in a container. This concept can also be adapted to the present invention. For this purpose, according to FIGS. 16 and 17, a plate  32  is connected to a container  12 . 11 . This plate  32  can be attached internally or externally to the container  12 . 11 . In a preferred example of embodiment, the plate  32  is suspended in a side wall  19 . 5  of the container  12 . 11 . For this purpose, two slits  33 . 1  and  33 . 2  are formed in an upper marginal edge  16 . 1 , the plate  32  engaging by means of a hook-shaped extension  34  into the slit  33 . 1  or  33 . 2 . The hook-shaped extension  34  preferably possesses a barb  35  by which it is anchored in the slit  33 . 1  or  33 . 2 . In addition, a predetermined breaking point may be provided close to the extension  34 . If the plate  32  is to be removed, it is raised upward in the direction z, so that the predetermined breaking point breaks and the extension  34  is released from the plate  32 . 
     The plate  32  may possess a wear indicator, as mentioned above. However, any desired inscription is also possible. 
     The figures do not show the fact that the containers  12  to  12 . 11  may also be provided with lids. These lids may have a similar shape to a positioned container, but are designed to be much less deep. It is also possible, however, for the containers  12  to  12 . 11  to be sealed, for example after the insertion of tools, with a film or similar skin which is removed from the container only before use of the tools. Many possibilities are conceivable here and are to be encompassed by the invention.
