The invention also relates to a tool holder assembly comprising the breadboard plate and the tool holder base insert, and a method of mounting the tool holder base insert to the breadboard plate of the tool holder assembly.

In garages, perforated sheets are often used to clean up tools so they are easily accessible. It is possible that a tool is suspended via a hook or similar mounting elements in the perforated plate. However, it is also known to use mounting devices which can be inserted into the perforated plate and which, for example, wireforms or round material structures for receiving tools.

For example, the document shows EP 180 836 A1 , which is probably the closest prior art, a holder for a perforated plate, wherein the holder has a base body with a first hook member which can be inserted into a first hole of the perforated plate and further hook elements, which in a second hole of perforated plate can be inserted. The second hook elements are integrally formed on legs of the main body, which are elastically deflectable, so that by squeezing the legs by a user, the second hook elements can be pressed to each other. In the mutually pressed state, the hook elements can then be inserted into the second hole. When the user releases the legs, they relax and the second hook elements press laterally against the boundaries of the hole thereby locking the holder in the perforated plate. On the main body of the holder, a sheet of a round material or wire is arranged, can be arranged in or on the tools.

The invention has for its object to provide a tool holder base insert for a breadboard, which forms an alternative to the known holders. This object is achieved by a tool holder base insert having the features of claim 1, by a tool holder assembly having the features of claim 13, and by a method of mounting the at least one tool holder base insert having the features of claim 15. Preferred or advantageous embodiments of the invention will become apparent from the dependent claims, the following description and the accompanying drawings.

In the context of the invention, a tool holder base insert is proposed which is suitable and / or designed for a breadboard. Functionally, the tool holder base insert is configured to hold at least one tool or tool holding device. The tool may be e.g. to act a screwdriver, ring spanner, open-end wrench, drill, pliers, cordless screwdriver, etc. Optionally, in addition, the tool holder base insert can also be used to hold workpieces such as e.g. Screws, nuts, etc. may be formed. Preferably, the tool holder base insert has at least one mechanical interface which is suitable and / or designed for holding a tool or for holding a tool holding device.

The breadboard is formed as a plate body, for example, as a plate having a plurality of receiving holes. The receiving holes define a plate-hole pattern. Particularly preferably, it is a regular plate-hole grid, with particular preference the grid spacing of the receiving holes in a transverse direction and a longitudinal direction perpendicular thereto are equal. The perforated grid plate is particularly preferably a sheet metal, wherein the receiving holes have a size of 9.2 millimeters × 9.2 millimeters and a spacing of 38.1 millimeters exhibit. This panel perforation has established itself - at least in Germany - as a well-known measure.

The tool holder base insert has a support surface, wherein the tool holder base insert in the assembled state rests with the support surface on the perforated grid plate, in particular on a front side of the perforated grid plate.

The tool holder base insert has at least one hook device, wherein the hook device protrudes beyond the support surface in a plug-in direction of the tool holder base insert into the perforated grid plate, in particular perpendicular to the support surface. The at least one hook means, some or all of the hook means is arranged relative to the support surface so that the hook means in the assembled state of the tool holder base insert can each pass through one of the receiving holes and project on the opposite side.

Looking more closely at the hook device, it has a hook leg and a hook head, the hook head being arranged on the hook leg. In particular, the longitudinal extension of the hook head is aligned perpendicular to the longitudinal extent of the hook leg. In particular, these form a reversed L-shaped hook in a side view. Together, the hook leg and hook head form a plate receiving portion for receiving a portion of the plate body, namely a plate edge portion facing the receiving hole into which the hook means is inserted. The hook device thus engages around the plate edge region forming the receiving hole. The hook leg forms a positive contact surface for the plate edge region and extends in particular perpendicular to the support surface. Over the contact surface, the tool holder base insert can be supported on the perforated grid plate, in particular on the facing plate edge region, in a loading direction. For example, if the breadboard is a vertically arranged breadboard, the loading direction is directed from top to bottom so that the hook means is opened downwardly and / or in the loading direction. The hook device lies with the contact surface on the plate edge area. The hook head engages over the plate edge region in the loading direction, so that the plate edge region is arranged between the hook head and the bearing surface.

Furthermore, the tool holder base insert comprises at least one securing device, which is arranged in the assembled state of the tool holder base insert in one of the receiving holes, in particular such that the securing device engages in or engages through the receiving hole. The securing device serves to secure the tool holder base insert in a form-locking manner against displacement relative to the perforated grid plate counter to the loading direction. Thus, the tool holder base insert is positively secured in the loading direction by the positive contact surface of the hook leg and against the loading direction by the securing device.

In the context of the invention it is proposed that the tool holder base insert has a main body portion and a securing portion. The body portion defines the bearing surface and carries the at least one hook means. The securing section, in contrast, carries the securing device. The main body portion and the securing portion are arranged to be movable relative to one another, wherein the securing means is elastically deflectable relative to the hook means against the insertion direction, in particular in a straight line or in a pivoting movement. For a deactivation of the securing device, this is deflected relative to the at least one hook device against the insertion in a Entsicherungsposition. For activation of the securing device is preferably provided that this automatically and / or elastically returns to the securing position.

It is a consideration of the invention that a tool holder base insert can be created by the use of a securing device which is deflectable in a direction opposite to the insertion and thus deactivated, which represents a different attachment approach than the known prior art and also against lateral loads is less sensitive than for example the holder mentioned in the prior art.

In a preferred embodiment of the invention, the main body portion and the securing portion are connected to each other via a pivot joint. The pivot axis is particularly preferably arranged parallel to the support surface. The pivot joint allows the pivoting of the securing device relative to the hook device. Characterized in that the pivot axis is arranged parallel to the support surface, the movement of the securing device against the insertion direction is made possible as a pivoting movement.

In a preferred embodiment of the invention, the securing portion is formed as a U-shaped securing bracket, which surrounds the body portion at least in sections and is connected at the free ends via the pivot joint with the base body portion. In particular, the pivot joint forms two pivot sections. In the training as a U-shaped securing bracket, the securing portion of a user can be particularly easily operated, since the connecting leg of the two free legs is easy to grip. Thus, it is possible, for example, to pull for disassembly of the tool holder base insert on the securing bracket, thereby elastically deflecting and deactivating the securing device against the insertion direction, so that the tool holder base insert can be dismantled. Particularly preferably, the base body portion is T-shaped, wherein the standing leg of the "T" between the legs of the "U" of the securing bracket is arranged. Particularly preferably, the end region of the upright leg of the "T" is designed as a first operating region, wherein the assembly can be effected by pressure loading on the first operating region. In this embodiment, the tool holder base insert presents itself as an easy-to-use, shapely and / or compact workshop component.

In a preferred development of the invention, the tool holder base insert has at least two of the hook devices. The hook heads of the at least two hook devices are arranged to be compatible with an imaginary positioning hole grid. The Positionierlochraster corresponds in the pitch of the plate hole grid and is used in the present description as a first auxiliary construction.

The hook legs of the at least two hook devices are arranged to be compatible with an imaginary fixing hole grid. The grid dimension of Fixierlochrasters corresponds to the grid dimension of the plate hole grid, wherein the Fixierlochraster represents a second auxiliary construction. In particular, the hook heads may be arranged in the positioning hole grid and / or the abutment surfaces of the hook legs in the Fixierlochraster. The Positionierlochraster is offset from the Fixierlochraster in a mounting direction of the tool holder base insert. When mounting the tool holder base insert in the perforated grid plate, it is initially positioned in a positioning position such that the hook heads of the at least two hook devices are arranged in the receiving holes. In the positioning position, the plate-hole grid forms the positioning-hole grid. In a subsequent step, the tool holder base insert is moved in the mounting direction to achieve a fixing position, wherein the hook legs are arranged in the plate hole grid and these bear against the bearing surfaces in the loading direction at the plate edge regions. In the fixing position, the plate-hole grid forms the fixing-hole grid. Due to the sliding movement in the assembly direction, the tool holder base insert is transferred from the positioning position into the fixing position.

Particularly preferably, the at least two hook means, some hook means, preferably all hook means, are oriented the same so that the tool holder base insert can be inserted in the insertion direction into the perforated grid plate and subsequently displaced in the mounting direction, the hook means engaging over the edge portions of the panel.

It is particularly preferred that the at least one securing device is arranged to be compatible with the fixing hole grid and / or incompatible with the positioning hole grid. Compatible means in particular that the securing device etc. fits into the corresponding grid and / or is arranged in the receiving holes. Incompatible means, in particular, that the securing device etc. does not fit into the corresponding grid and / or is arranged outside, in particular shifted, to the receiving holes. In particular, the tool holder base insert is designed so that in the arrangement of the tool holder base insert in the positioning position, the securing device is elastically deflected relative to the hook device against the insertion direction and is in particular inevitably in the armed position. Only after the transfer of the tool holder base insert into the fixing position can the transition of the securing device into the securing position take place.

The securing device is particularly preferably designed such that it rests in the positioning position of the tool holder base insert on the perforated grid plate, in particular on a front side of the perforated grid plate and is inserted into the corresponding receiving hole only after transfer of the tool holder base insert into the fixing position or elastically snaps. In order to simplify the insertion into the corresponding receiving hole is proposed to introduce a control slope on the securing device. The control slope is arranged on the securing device such that the edge region of the perforated grid plate can slide in the receiving hole during insertion of the securing device. Due to the control slope, the securing device and thus the tool holder base insert is displaced in the assembly direction at a pressure load perpendicular to the perforated grid plate on the tool holder base insert. In particular, the control slope thus forms an auxiliary gear section for mounting the tool holder base insert.

In a particularly preferred embodiment of the invention, the securing device is designed as a web section, wherein the Web section with a web end counter to the loading direction can be positively supported on the plate edge region. Thus, the fixing position of the tool holder base insert is fixed to the web end opposite to the loading direction and on the other by the contact surface of the hook leg in the loading direction. Optionally, in addition, it can be provided that the web portion can also be supported with the other web end in the loading direction on the plate edge region. However, since this can lead to an over-definition of the tool holder base insert, it is more preferred that in the loading direction, the web end is set back slightly relative to the contact surface.

It is particularly preferred that the securing device and one of the hook devices are arranged in the assembled state of the tool holder base insert and / or in the fixing position in a common receiving hole. Alternatively or additionally, the securing device and the hook device are positioned in the Justierlochraster in a common receiving hole. This positioning has the advantage that the bilateral positive support of the securing device, in particular the web end, and the hook leg, in particular the contact surface, takes place within a very small area, so that no tilting or other disturbances can occur. Further, the number of required receiving holes for mounting the tool holder base insert is reduced, so that more of the tool holder base inserts or the tool holder base inserts can be arranged closer to each other on the breadboard, since no separate receiving hole for the securing device must be kept free.

In one possible implementation of the invention, the tool holder base insert is designed as a base tool holder base insert, which has at least or exactly four hook devices and has at least or exactly two securing devices. It is preferably provided that the hook devices are arranged in a square pattern and / or in a 2 × 2 matrix. Particularly preferably, the two securing devices are arranged in the manner of a clip around two of the hook devices within a row, preferably around the two hook devices which are down in the loading direction. It is further preferred that the pivot axis is arranged between, in particular centrally between the two rows of the 2 × 2 matrix.

In another embodiment of the invention, the tool holder base insert is designed as a supplementary tool holder base insert which has at least or exactly two hook devices and at least or precisely comprises a securing device. It is particularly preferably provided that the hook devices are arranged one above the other in the loading direction and the securing device is positioned next to the lower hook device in the loading direction.

In an advantageous embodiment of the invention, the tool holder base insert has at least one mechanical plug-in interface for a tool holding device, wherein the plug-in interface, e.g. is formed as a passage opening. For example, the passage opening may have a circular cross-section, so that a round material, such as a rod, can be introduced. In an alternative or additional embodiment of the invention, the tool holder base insert comprises at least one mechanical slide interface for a tool holder device, wherein the tool holder device can be pushed onto the tool holder base insert. It is particularly preferred that the tool holder base insert comprises both the mechanical plug-in interface and the mechanical slide interface.

For the slide interface, the tool holder device has a slide holder and the tool holder base insert has a slide portion. Slide holder and slide portion together form the slide interface for coupling the tool holder device with the tool holder base insert. The tool holder device can be pushed onto the at least one tool holder base insert. This is done by a sliding movement in a mounting direction. The mounting direction is rectified or parallel to a mounting plane or is in the mounting plane. The mounting plane is preferably rectified or parallel to a front side of the breadboard.

In the state where the tool holder device is completely pushed onto the at least one tool holder base insert, in particular as far as an end stop, the tool holder device and the tool holder base insert are in a connected state.

The slider section has at least one rail section and the slider receiving section has at least one rail wing section. During the sliding movement, in particular in a sliding state, the rail section and the rail wing section come into direct contact and / or operative connection, wherein the at least one rail wing section is guided by the at least one rail section.

Optionally, in addition, it is proposed that in the connection state, the at least one rail section secures the at least one rail wing section in a direction perpendicular to the mounting plane in a form-fitting manner. In particular, it is provided that the rail wing section engages behind the at least one rail section and thereby secures positively against the rail section. Due to the positive locking ensures that a movement of the tool holder device is positively locked in a direction perpendicular to the mounting plane and thus perpendicular, substantially perpendicular or angled to the surface extension of the hole grid plate. More specifically, in the connection state, the rail wing portion is disposed between the breadboard plate and the tool holder base insert.

It is a further consideration that by the dual function of the sliding interface components rail section and rail wing section, namely both the guide function in the sliding state and the backup function in the connection state, an improved connection of the tool holder device can be implemented on the tool holder base insert. The fact that the sliding interface components rail section rail wing section are already used during assembly, they can be made very large or long in the surface extension, especially in the mounting direction, so that a secure and stable support of the rail section on the rail section and thus a secure connection Tool holder device can be achieved via the tool holder base insert on the breadboard.

In a preferred constructional realization, the rail section has a sliding surface and the rail wing section has a mating sliding surface, these two surfaces being rectified. In particular, the sliding surface and / or the counter sliding surface are rectified and particularly preferably arranged or aligned parallel to the mounting plane. In a preferred structural embodiment, the mating sliding surface and / or the sliding surface or portions thereof define the mounting plane. Through this structural realization is achieved that the tool holder device can be slid in the mounting direction on the tool holder base insert slidably and at the same time secured in a form-fitting manner.

In a preferred embodiment of the invention, the slide portion has a support area and the slider receiving a support area, wherein the support area rests positively in the connection state in the mounting direction on the support area. In particular, the support region forms an end stop for the support region of the slide holder of the tool holder device. Through this development it is achieved that the tool holder device is held positively in the mounting direction and preferably in a loading direction. Together with the positive locking perpendicular to the mounting plane, the tool holder device can be fastened in a form-fitting manner to the tool holder base insert.

In a preferred embodiment of the invention, the tool holding device, in particular the slide holder, a latching device and the tool holder base insert, in particular the slide portion, a locking receptacle. Alternatively, the tool holder device may comprise the latching receptacle and the toolholder base insert may comprise the latching device.

By the latching interface is achieved that the tool holder device can not be accidentally dismantled by a slight movement against the mounting direction.

In an optional development of the invention, the tool holding device, in particular the slide holder, a guide wing, which extends in a transverse direction to the mounting direction and at the same time rectified, in particular parallel to the mounting plane. The guide wing is used for centering and / or guiding of the free end of the tool holder base insert, in particular of the slide portion, in the sliding movement. In particular, in the connection state, the guide vanes are arranged between the perforated grid plate and the free end of the tool holder base insert, in particular the slide section.

In a preferred development of the invention, it is provided that the tool holder base insert has a guide surface and the tool holder device has a counter guide surface. The guide surface or the counter guide surface are aligned rectified to the mounting plane and / or define the mounting plane. In particular, the guide surface is located on a front side of the tool holder base insert facing away from the perforated grid plate or the plate interface. In contrast, the counter guide surface is located on a rear side or inside of the tool holder device facing the tool holder base insert in the connection state. When pushing the tool holder device is this by a Active connection, in particular a sliding sliding of guide surface and mating surface guided in the sliding movement.

In particular, it is provided that the tool holder base insert is guided from the rear side through the mating sliding surface and on the front side through the mating guide surface relative to the tool holding device. Due to the two-sided relative guidance a tilt-free and easy mounting of the tool holder device on the tool holder base insert is possible.

It is particularly preferably provided that the mounting direction for the rectified for the tool holder base insert and for the tool holder device, parallel or identical and optionally complementary rectified, is parallel or identical to the loading direction

In a preferred embodiment of the invention, the tool holder base insert is formed as a one-piece injection molded part. In particular, the pivot joint is formed as an integral part of the injection molded part and can be implemented, for example, by a material taper. In this realization, the tool holder base insert can be produced very simply and thus inexpensively.

The invention may also relate to a set comprising one of the tool holder inserts and one of the tool holder devices. Another object of the invention relates to a tool holder assembly comprising the perforated grid plate and at least one of the tool holder inserts and at least one of the tool holder devices, as described above or according to one of the preceding claims.

The tool holder assembly may be formed, for example, as a tool cart, wherein the hole grid plate is arranged on a front side of the tool carriage and secured thereto. The tool holder inserts can be optionally placed on the breadboard. In particular, the tool holder inserts make it possible to form rows and columns and in particular to arrange the tool in a more visually ordered manner in any desired manner.

In the 4a is a schematic sectional view shown to the assembly of the tool holder base insert 3 on or in the breadboard 2 to describe. The breadboard 2 is in the process 4a shown in triplicate, with the perforated grid plate 2 here as 2a , b, c is designated. The breadboard 2a is in a plug-in direction E, which is perpendicular to the surface extension of the hole grid plate 2a , b, c and / or perpendicular to the support surface 11 oriented, spaced from the toolholder base insert 3 arranged. This relative positioning is also in the 4b shown.

The breadboard 2 B is positioned so that the toolholder base insert 3 is in a positioning position. In the positioning position are the hook heads 13 the hook devices 8th already in the receiving holes 4 the breadboard 2 immersed. In the adjustment position of the tool holder base insert 3 the safety devices are based 14 however, at the front of the breadboard 2 B from. This relative position is in the 4c shown.

Looking at the parallel to this 5 , which is a rear view of the tool holder assembly 1 shows, wherein the tool holder base insert 3 is in the adjustment position, it can be seen that the hook heads 13 longitudinally and transversely positively from the grid plate 2 B are included. The breadboard 2 B defines a positioning hole grid relative to the tool holder base insert 3 ,

By loading the body portion 5 in the area of the upright leg on the first operating area 19 according to arrow A in the insertion direction E is achieved that the hook means 8th the lower row and also the hook devices 8th the top row continues through the receiving holes 4 be carried out, at the same time the security devices 14 relative to the lower row of hook means 8th and / or relative to the adjacent hook means 8th be deflected against the insertion direction E. Once the hook heads 13 so deep into the receiving holes 4 Are immersed in that the back of the breadboard 2 B in the reception areas 9 can retract, the tool holder base insert 3 in the mounting direction M and / or later load direction B relative to the hole grid plate 2 B be moved so that the tool holder base insert 3 is transferred to a fixation. In particular, the insertion movement is strictly and / or exclusively parallel to the front of the breadboard 2 respectively. 2a , b, c. During the transfer into the fixing position slides the safety device 14 over the front of the breadboard 2 B , Once the tax slope 21 the edge region of the receiving hole 4 achieved, the safety device 14 in the reception hole 4 slide into. By the control slope 21 becomes the toolholder base insert 3 pushed further in the mounting direction M, since this is a translation of the pressurization in the direction of E and / or perpendicular to the hole grid plate 2 converted into a translational movement in mounting direction M.

The fixing position of the tool holder base insert 3 is relative to the breadboard 2c or in the 4d shown. In the fixing position, the hook devices are supported in the loading direction B. 13 over the contact surfaces 10 the hook leg 12 positive fit at the edge areas of the plate plate 2c from. Due to the offset of the tool holder base insert 3 relative to the breadboard 2 B are now the safety devices 14 congruent with the receiving holes 4 brought so that they in the insertion direction E in the receiving holes 4 can be introduced. The hook heads 13 On the other hand, they grip over the edge areas of the plate.

This condition is again in the 6 shown in the synopsis of the 4 and 6 It can be seen that the safety devices 14 supported on one end, in particular web end positively against the plate edge regions against the mounting direction M and / or the loading direction B. This is the tool holder base insert 3 both in and against the loading direction B and / or mounting direction M positively in the breadboard 2c arranged. Against removal of the tool holder base insert 3 against the plug-in direction E is a backup on the cross-hook heads 13 and those in the reception areas 9 recorded plate edge areas of the breadboard 2c , This is the tool holder base insert 3 secured positively in each direction of movement.

When disassembling the tool holder base insert 3 becomes the security section 6 opposite the body portion 5 around the swivel joint 7 by a train on the second operating area 20 pivoted so that the safety device 14 from the recording hole 4 is pulled out. By the pulling movement on the second operating area 20 becomes the toolholder base insert 3 against the mounting direction, that is pressure-loaded in a disassembly direction, so that the tool holder base insert 3 in a total movement of the breadboard 2 is removable. This is achieved in that the pulling movement in opposite directions to the extension direction of the hook heads 13 on the hook devices 8th is aligned.

The position of the breadboard 2c relative to the toolholder base insert 3 defines a locating hole grid with the locating hole grid in relation to the toolholder base insert 3 is arranged offset in the mounting direction M to the positioning hole grid.

As can be seen in particular from the 6 results are the hook means 8th the upper row as wide hook devices 8th formed, which are also in the transverse direction Q at the plate edge portions of the receiving holes 4 support. In contrast, the hook devices 8th in the lower row as narrow hook devices 8th formed, which are positively supported only on one side of the transverse direction Q at the edge regions of the plate. On the opposite side, however, is in the same receiving hole 4 each one of the safety devices 14 arranged. Because of that in a common receiving hole 4 both a safety device 14 as well as a hook device 8th arranged, tilting and similar interference that might occur when these components are in different receiving holes 4 are arranged minimized.

As can be seen in particular from the 3 indicates the tool holder base insert 3 a plurality of tubular support sections 15 on, which in the embodiment shown in the 1 are closed at the front. However, these can be opened by a separating machining, for example a hole, and thereby form plug-in interfaces for insertion of a round material, which can be designed as a tool holding device.

Furthermore, the tool holder base insert 3 on the transverse leg of the T-shaped body portion 5 edge portions extending in the longitudinal direction L rail sections 16a , b on, on which an attachment body, such as one of the tool holders described below 18 , can be postponed so that they form a common sliding interface.

The in the 1 to 6 shown tool holder base insert 3 is square or nearly square in shape and shows a 2 × 2 matrix of hook means 8th , This may be referred to as a base tool holder base insert.

In the 7 and 8th is a tool holder base insert 3 shown as a supplemental tool holder base insert in the front view and in the rear view, this only two hook means 8th which are arranged one above the other in a 2 × 1 matrix. The tool holder base insert 3 has exactly one safety device 14 on, which again together with the lower hook device 8th in a common reception hole 4 can be introduced. Also, the tool holder base insert formed as a supplementary tool holder base insert 3 has a T-shaped body portion 5 and a U-shaped securing portion 6 on, so that the function is referred to the previous description.

In the 9b are different tools holder inserts 3 when using the rail sections 16a , b for pushing tool holder devices 18 shown. For illustration, the show 10a , b the tool holder device 18 or the tool holder base insert 3 with the tool holder device 18 in detail. The tool holder device 18 is designed as a sliding cap, which acts as the rail sections 16a , b formed rail interface of the tool holder base insert 3 can be pushed from above in the direction of loading B and the tool holder base insert 3 engages positively. The tool holder device 18 may have different retaining members, wherein in the examples XVI and XVII hook elements are shown. In Examples XVIII-XXI sorting boxes for tool inserts or other small parts as a tool holder device 18 shown. While trained as sliding caps tool holder device 18 in Examples XVI-XIX, only on a single toolholder base insert 3 are deferred, the tool holder device 18 of example XX and XXI on two tool holder inserts 3 deferred, which are also arranged offset to each other.

The 10a , b show the tool holder device 18 in a schematic rear view and in an oblique view from the rear. The tool holder device 18 has a slide holder 22 in which a slider section 23 ( 3 ) can be inserted in the mounting direction. The slider section 23 is as a free end or as a free end portion of the tool holder base insert 3 educated.

The tool holder device 18 , more precisely, the slider recording 22 , has two rail wing sections 24a , b, which extend in the mounting direction M or in the loading direction B. The rail sections 16a , b ( 3 ) each have a sliding surface 25a , b on, on the other hand show the rail wing sections 24a , b each have a counter sliding surface 26a , b. The sliding surfaces 25a , b are in the mounted state of the breadboard 2 facing, the Gegengleitflächen 26a , b are on the other hand from the breadboard 2 turned away. In particular, the rail wing sections engage behind 24a , b the rail sections 16a , b in the insertion direction E, so that the rail wing sections 24a , b and in particular the counter sliding surfaces 26a , b between the breadboard 2 and the rail sections 16a , b or the sliding surfaces 25a , b is located.

The tool holder base insert 3 also has a guide surface 27 which passes through the front of the toolholder base insert 3 is formed. By contrast, the tool holder device comprises 18 a mating surface 28 , which in the slide holder 22 is arranged and the tool holder base insert 3 is facing so that when mounting the tool holder device 18 on the tool holder base insert 3 the counterfeiting surface 28 on the guide surface 27 can slide along. The counterpart surface 28 can be formed continuously, or - as in the 10a , b shown - be realized only as in the mounting direction M running ribs.

The slide holder 22 forms a hood, with the end of the hood through a support area 29 is formed, to which the free end of the tool holder base insert 3 , in particular of the slide section 23 , with a support area 30 ( 3 ) rests positively. In particular, the support area forms 30 an end stop for the support area 29 in mounting direction M and / or in loading direction B.

In order to further improve insertion and threading, a guide wing extends in the transverse direction Q. 31 which in a connection state, the free end of the tool holder base insert 3 engages behind. The guide wing 31 is at the tool holder device 18 formed.

With the aim of accidentally releasing the tool holder device 18 from the tool holder base insert 3 to prevent, has the tool holder device 18 two locking device 32a , b on, which are designed as latching hooks and which in locking receptacles 33a , b of the tool holder base insert 3 engage with restraint. The locking devices 32a , b form each with the snap shots 33a , b a latching interface, which the tool holding device 18 with the tool holder base insert 3 releasably secured against the mounting direction.

The 11a , b, c show three states during the sliding of the tool holder device 18 on the tool holder base insert 3 along or rectified to the mounting direction M. By pushing a mounting plane ME is defined at the same time, which is rectified or parallel to the mounting direction M. Further, the mounting plane ME is rectified or parallel to the front of the breadboard 2 aligned, in the 11a is the tool holder base insert 3 between the mating surface 28 and the counter-sliding 26a , b positively caught and thereby centered in the sliding movement. The game in the direction perpendicular to the mounting plane is large, so that the tool holder device 18 in a simple manner on the tool holder base insert 3 can be put on.

In the 11b is the tool holder device 18 so far on the tool holder base insert 3 pushed so that the free end of the tool holder base insert 3 from the guide wing 31 already underreaching, thereby further centering the movement.

Upon further pushing on the tool holder device 18 on the tool holder base insert 3 become the locking devices 32a , b in the snap shots 33a , b engaged and the connection state reached. The counterpart surface 28 and the mating surfaces 26a , b hold the tool holder base insert 3 over the guide surface 27 and the sliding surfaces 25a , b free of play, almost no play or even with a certain bias. By engaging behind the rail wing sections 24a , b behind the rail sections 23 is the tool holder device 18 in a direction perpendicular to the surface extension of the breadboard 2 and / or the mounting plane secured in a form-fitting manner.

The sliding surfaces 25a , b, counter sliding surfaces 26a , b, guide surface 27 and mating surface 28 can be so dimensioned that in which in the 11a -C transition shown the game in the direction perpendicular to the mounting plane and / or the centering is steadily narrower, so that from a rough recording to a biased state, a narrowing occurs.

In the 12 is the tool holder device 18 formed in this case as a forceps holding device in a three-dimensional representation obliquely from the front in a detailed view. The trained as a forceps holder tool holder device 18 has two shots 34a , b on, whose receiving direction is vertically aligned and forms a receiving channel for a first leg of a pair of pliers. In the tool holder device shown 18 Thus, two pliers can be inserted in parallel. It should be emphasized that the edge of the tool holder device 18 two cheek sections 35a , b are arranged, which in the surface extension approximately at right angles to the breadth of the grid 2 and / or extend to the mounting plane and form a lateral boundary for the respective second leg of the pliers. Along with the limitations of the recordings 34a , b form the cheek sections 35a , b a U-shaped area for the second leg of the pliers. In the inserted state of the forceps is thus the first leg of the forceps by the recording 34a , b and the second leg of the forceps through the cheek sections 35a , b guided sideways, so that the pliers can not swing or swing uncontrollably. In particular, this ensures that the space for receiving the pliers on the extension in the transverse direction Q of the tool holder device 18 is limited.

It should be noted that the tool holding inserts 3 in the form of a base tool holder base insert and a supplementary tool holder base insert for the tool holders, respectively 18 in the 9a and 9b are each designed identical. In particular, these can each be manufactured in a tool and thereby form a highly functional module mounting plate for the tool holding arrangement 1 ,
