Description

The invention relates to a tool holder arrangement for a perforated grid plate with the features of the preamble of claim 1 and the use of a tool holder device in the tool holder arrangement.

In workshops, perforated panels are often used to hang up tools so that they are easily accessible. It is possible to hang a tool on the perforated panel using a hook or similar mounting elements. However, it is also known to use mounting devices that can be inserted into the perforated panel.

The publication DE 20 2010 016 696 U1 discloses a holder for storing work equipment, such as tools or fastening means, on a perforated wall with a fixing side on which fixing means are provided for fixing to the perforated wall, and with receiving means by means of which at least one of the work equipment can be received on a receiving side facing away from the fixing side.

The publication EP 2 165 875 B1 discloses a fastening device for fastening an attachment to a supporting part, in particular of a motor vehicle, with at least one suspension device which has a supporting element fastened or fastenable to the supporting part, an attachment element fastened or fastenable to the attachment and a securing element.

The publication US 2008 169 255 A1 discloses a storage assembly for attachment to a wall support member. The storage assembly includes a hanging tab and a locking tab. The locking tab is movable between an unlocked position and a locked position. In the unlocked position, the locking tab is configured such that it cannot enter a groove in a wall support member, thus preventing removal of the hanging tab from a wall support member.

The publication DE 20 2011 107 089 U1 discloses a holder for storing work equipment, such as tools or fastening means, on a perforated wall with a rear side, on which fastening means are provided for fastening to the perforated wall, and with a base element to which receiving means can be attached, by means of which at least one of the work equipment can be received on a receiving side facing away from the rear side. The fastening means have at least one gripping element protruding from the base element on the rear side and a securing element that can be secured to the base element.

The publication US 6481 583 B1 relates to a tool holder system for a wall with a regular grid of holes, the tool holder system having mounting elements and attachment elements. In a first step, the mounting elements are fixed in the perforated wall, in a second step the attachment elements are pushed onto the mounting elements. The mounting elements have hooks for fastening to the perforated wall, with which they reach through the perforated wall. To accommodate the attachment element, the mounting elements have further hooks which face the attachment elements and into which the attachment element can be positively received and locked.

The invention is based on the object of proposing a tool holder arrangement for a perforated grid plate, which enables reliable fastening to the perforated grid plate. This object is achieved by a tool holder arrangement with the features of claim 1 and with a use with the features of claim 14. Preferred or advantageous embodiments of the invention emerge from the subclaims, the following description and the attached figures.

A tool holder arrangement is proposed which is suitable and/or designed for a perforated grid plate. From a functional point of view, the tool holder arrangement is designed to hold at least one tool. The tool can be, for example, a screwdriver, ring spanner, open-end wrench, drill, pliers, cordless screwdriver, etc. Optionally, the tool holder arrangement can also be designed to hold workpieces, such as screws, nuts, etc. In particular, the tool holder arrangement has at least one mechanical interface which is suitable and/or designed to hold a tool and/or to hold a tool holder device.

The perforated grid plate is designed as a plate body, for example as a sheet metal, with a large number of receiving holes. The receiving holes define a plate hole grid. It is particularly preferred to have a regular plate hole grid, in particular the grid spacing of the receiving holes in a transverse direction and a longitudinal direction perpendicular thereto being the same. It is particularly preferred to have the perforated grid plate as a sheet metal, in which the receiving holes have a size of 9.2 millimeters x 9.2 millimeters and a Distance from each other of 38.1 millimeters. This plate hole grid has established itself as a well-known measurement - at least in Germany.

The tool holder arrangement comprises at least one tool holder base insert, wherein the tool holder base insert can be and/or is attached directly and/or in contact with the perforated grid plate. For this purpose, the tool holder base insert has a plate interface which enables the mechanical coupling with the perforated grid plate.

The tool holder arrangement comprises one or more tool holder devices which are suitable and/or designed to hold at least one tool or tool accessory. The tool holder device can be coupled or is coupled to the tool holder base insert, so that the tool holder device is fastened to the perforated grid plate, in particular indirectly via the at least one tool holder base insert. In particular, the tool holder base insert forms an adapter plate for fastening the tool holder device to the perforated grid plate.

For coupling, the tool holder device has a slider receptacle and the tool holder base insert has a slider section. The slider receptacle and slider section together form a slider interface for coupling the tool holder device to 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 an assembly direction. The assembly direction is aligned or parallel to an assembly plane or lies in the assembly plane. The assembly plane is preferably aligned or parallel to a front side of the perforated grid plate. The tool holder device preferably has a base surface which rests on the front side during assembly or is supported on it, so that the base surface is aligned to the assembly plane or forms it.

In the state in which the tool holder device is completely pushed onto the at least one tool holder base insert, in particular up to 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 receptacle 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.

Within the scope of the invention, it is proposed that in the connected state, the at least one rail section positively secures the at least one rail wing section in a direction perpendicular to the mounting plane. In particular, it is provided that the rail wing section engages behind the at least one rail section and thereby positively secures itself to the rail section. The positive securing ensures that a movement of the tool holder device in a direction perpendicular to the mounting plane and thus perpendicular, substantially perpendicular or angled to the surface extension of the perforated grid plate is positively prevented. In particular, in the connected state, the rail wing section is arranged between the perforated grid plate and the tool holder base insert.

One consideration of the invention is that the dual function of the sliding interface components rail section and rail wing section, namely both the guiding function in the sliding state and the securing function in the connected state, enables an improved connection of the tool holder device to the tool holder base insert. Because the sliding interface components rail section and rail wing section are already used during assembly, they can be made very large or long in terms of their surface area, particularly in the assembly direction, so that a secure and stable support of the rail wing section on the rail section and thus a secure connection of the tool holder device via the tool holder base insert to the perforated grid plate can be achieved.

In a preferred structural implementation, the rail section has a sliding surface and the rail wing section has a counter-sliding surface, with these two surfaces being aligned in the same direction. In particular, the sliding surface and/or the counter-sliding surface are aligned in the same direction and particularly preferably arranged or aligned parallel to the mounting plane. In a preferred structural design, the counter-sliding surface and/or the sliding surface or sections thereof define the mounting plane. This structural implementation ensures that the tool holder device can be slid onto the tool holder base insert in the mounting direction and at the same time secured in a form-fitting manner.

In a preferred development of the invention, the slide section has a support area and the slide receptacle has a support area, wherein the support area in the connected state rests positively on the support area in the assembly direction. In particular, the support area forms an end stop for the support area of the slide receptacle of the tool holder device. This development ensures that the tool holder device is held positively in the assembly direction and preferably in a loading direction. Together with the positive locking perpendicular to the assembly plane, the tool holder device can be fastened positively to the tool holder base insert.

According to the invention, the tool holder device, in particular the slider holder, has a locking device and the tool holder base insert, in particular the slider section, has a locking receptacle. Alternatively, the tool holder device can have the locking receptacle and the tool holder base insert can have the locking device. The locking device and the locking receptacle together form a locking interface, wherein in the connected state the slider section in the slider holder is locked by the locking interface against opening of the tool holder device, i.e. against movement against the assembly direction. The locking interface ensures that the tool holder device cannot be accidentally dismantled by a slight movement against the assembly direction.

In an optional development of the invention, the tool holder device, in particular the slider holder, has a guide wing which extends in a transverse direction to the mounting direction and at the same time in the same direction, in particular parallel to the mounting plane. The guide wing serves to center and/or guide the free end of the tool holder base insert, in particular the slider section, during the sliding movement. In particular, in the connected state, the guide wing is arranged between the perforated grid plate and the free end of the tool holder base insert, in particular the slider 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 in the same direction as 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. The counter-guide surface, on the other hand, is located on a rear side or inside of the tool holder device facing the tool holder base insert in the connected state. When the tool holder device is pushed on, it is guided by an active connection, in particular by the guide surface and the counter-guide surface sliding against one another during the sliding movement.

In particular, it is provided that the tool holder base insert is guided from the rear through the counter sliding surface and on the front through the counter guide surface relative to the tool holder device. The relative guide on both sides enables the tool holder device to be mounted on the tool holder base insert easily and without jamming.

In a preferred implementation of the invention, the tool holder base insert is designed as a plate section or as a plate, in particular as a mounting plate or adapter plate, which has a rail section on two sides, in particular long sides. The rail sections are spaced apart from one another by at least 2 centimeters, preferably by at least 4 centimeters. Alternatively or optionally in addition, it is provided that the tool holder device comprises a hood section which is pushed over the tool holder base insert, wherein the hood section has a rail wing section on two sides, preferably on one long side of the hood section. The rail wing sections are spaced apart from one another by at least 2 centimeters, preferably by at least 4 centimeters. The tool holder arrangement in this implementation underlines that the sliding interface formed by the rail sections or rail wing sections is designed to be wide in the transverse direction, so that tilting or twisting of the tool holder device is impossible.

In a preferred structural implementation, it is provided that the support area and/or the at least one locking device and/or the guide wing is located between the wing sections. In particular, the wing sections, the at least one locking device and the guide wing are lined up in the transverse direction. For example, in the transverse direction, two wing sections are initially arranged on the outside, followed by two locking devices and the guide wing is arranged between the locking devices.

In a possible implementation of the invention, the tool holder device is connected in the connected state to exactly one tool holder base insert. In this embodiment, It is intended that the two rail wing sections of the tool holder device engage in the two rail sections of the tool holder base insert. The plate-shaped design of the tool holder base insert ensures that the tool holder device is securely attached in a way that prevents it from tipping over and is comfortable.

In an alternative embodiment of the invention, the tool holder device is connected in the connected state to two, in particular exactly two, tool holder base inserts. In this embodiment, a connection to one of the tool holder base inserts is provided at one end region of the tool holder device with a rail wing section of the tool holder device and a further connection to the other tool holder base insert is provided at the other end region with the other rail wing section. In this embodiment, it is possible to create tool holder devices which extend over a width in the transverse direction over exactly two tool holder base inserts or - if there are free spaces between the tool holder base inserts - extend over a larger width.

In a preferred development of the invention, the tool holder arrangement comprises a plurality of structurally and/or functionally different tool holder devices and a plurality of tool holder base inserts, each of which is structurally identical. With this set of tool holder devices and tool holder base inserts, it is possible to equip and individualize a perforated grid plate in a desired manner. In particular, the tool holder arrangement comprises the perforated grid plate. The tool holder arrangement can be designed, for example, as a tool trolley, with the perforated grid plate arranged on one end of the tool trolley and fastened to it. The tool holder inserts can be optionally placed on the perforated grid plate. In particular, the tool holder inserts make it possible to form rows and columns and to arrange the tool in any way, in particular in a more visually ordered manner.

The tool holder device and/or the tool holder base insert are particularly preferably designed as a plastic part, in particular each as a one-piece plastic part, specifically a plastic injection-molded part. In the design as plastic injection-molded parts, in addition to or as an alternative to the functional division of the two parts, there is also the possibility of defining the demolding directions for the plastic injection-molded parts in such a way that the tools for the plastic injection-molded parts can be easily designed. It is preferred that the demolding direction for the tool holder base insert is aligned perpendicular or substantially perpendicular to the mounting plane and/or the surface extension of the perforated grid plate. The demolding direction is thus aligned with an insertion direction of the tool holder base insert into the perforated grid wall. In contrast, it is preferred that the demolding direction of the tool holder device is aligned perpendicular or substantially perpendicular to the demolding direction for the tool holder base insert and/or aligned with the mounting direction. This means that the demoulding direction is oriented to the assembly direction and, in many cases, to the loading direction for loading the tool holder device with tools.

In a preferred embodiment of the invention, the or one of the tool holder devices is designed as a pliers holder device, wherein the pliers holder device has one or more receptacles for a first pliers leg of a pair of pliers and cheek sections which are arranged offset from one another on the pliers holder device in the transverse direction for guiding a second pliers leg of the same pliers. The cheek sections ensure that the pliers, in particular the second pliers leg, cannot swing freely and penetrate into the gripping area of an adjacent tool holder device. On the other hand, the cheek sections ensure that the pliers are easy to grip and easy to put down.

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.

In a preferred embodiment, the plate interface has at least one hook device, wherein the hook device projects beyond the support surface in an insertion direction of the tool holder base insert into the perforated grid plate, in particular perpendicular to the support surface. The at least one hook device, some or all of the hook devices is or are arranged relative to the support surface such that the hook device can reach through one of the receiving holes in the assembled state of the tool holder base insert and projects over on the opposite side.

If you look at the hook device more closely, you will see that it has a hook shank and a hook head, with the hook head being arranged on the hook shank. In particular, the The longitudinal extension of the hook head is aligned perpendicular to the longitudinal extension of the hook leg. In particular, in a side view they form an inverted L-shaped hook. Together, the hook leg and hook head form a plate receiving area for receiving a section of the plate body, namely a plate edge area which faces the receiving hole into which the hook device is inserted. The hook device thus encompasses the plate edge area forming the receiving hole. The hook leg forms a positive contact surface for the plate edge area and extends in particular perpendicular to the support surface. The tool holder base insert can be supported on the perforated grid plate, in particular on the facing plate edge area, in a loading direction via the contact surface. If, for example, the perforated grid plate is a vertically arranged perforated grid plate, the loading direction is from top to bottom, so that the hook device is open downwards and/or in the loading direction. The hook device rests with the contact surface on the plate edge area. The hook head overlaps the plate edge area in the direction of loading so that the plate edge area is located between the hook head and the support surface.

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

Optionally, it is additionally proposed that the tool holder base insert has a base body section and a securing section. The base body section defines the support surface and carries the at least one hook device. The securing section, on the other hand, carries the securing device. The base body section and the securing section are arranged so that they can move relative to one another, wherein the securing device can be elastically deflected relative to the hook device against the insertion direction, in particular in a straight line or in a pivoting movement. To deactivate the securing device, it is deflected relative to the at least one hook device against the insertion direction into a release position. To activate the securing device, it is preferably provided that it returns automatically and/or elastically to the securing position.

One consideration of this design is that by using a safety device which can be deflected in a direction opposite to the insertion direction and can thus be deactivated, a tool holder base insert can be created which is very insensitive to lateral loads.

In a preferred embodiment of the invention, the base body section and the securing section are connected to one another via a swivel joint. The swivel axis is particularly preferably arranged parallel to the support surface. The swivel joint allows the securing device to be swiveled away relative to the hook device. Because the swivel axis is arranged parallel to the support surface, the movement of the securing device against the insertion direction is made possible as a swivel movement.

In a preferred implementation of the invention, the securing section is designed as a U-shaped securing bracket which at least partially encompasses the base body section and is connected to the base body section at the free ends via the swivel joint. In particular, the swivel joint forms two swivel sections. When designed as a U-shaped securing bracket, the securing section can be operated particularly easily by a user, since the connecting leg of the two free legs is easy to grip. For example, it is possible to pull on the securing bracket to disassemble the tool holder base insert, thereby elastically deflecting and deactivating the securing device against the insertion direction, so that the tool holder base insert can be disassembled. The base body section is particularly preferably T-shaped, with the standing leg of the "T" being arranged between the legs of the "U" of the securing bracket. The end region of the standing leg of the "T" is particularly preferably designed as a first operating region, whereby assembly can be carried out by applying pressure to the first operating region. In this design, the tool holder base insert is an easy-to-use, attractively designed 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 compatible with an imaginary positioning hole grid. The positioning hole grid corresponds in its grid dimension to the plate hole grid and serves as a first auxiliary construction in the present description.

The hook legs of the at least two hook devices are arranged in a way that is compatible with an imaginary fixing hole grid. The grid dimension of the fixing hole grid corresponds to the grid dimension of the plate hole grid, with the fixing hole grid representing a second auxiliary structure. In particular, the hook heads can be arranged in the positioning hole grid and/or the contact surfaces of the hook legs can be arranged in the fixing hole grid. The positioning hole grid is arranged offset from the fixing hole grid in an assembly direction of the tool holder base insert. When the tool holder base insert is assembled in the hole grid plate, it is first positioned in a positioning position so 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 assembly direction in order to reach a fixing position, with the hook legs being arranged in the plate hole grid and these resting with the contact surfaces in the load direction on the plate edge areas. In the fixing position, the plate hole grid forms the fixing hole grid. The sliding movement in the assembly direction moves the tool holder base insert from the positioning position into the fixing position.

Particularly preferably, the at least two hook devices, some hook devices, preferably all hook devices, are oriented in the same way, so that the tool holder base insert can be inserted into the perforated grid plate in the insertion direction and subsequently moved in the assembly direction, wherein the hook devices overlap the plate edge regions.

It is particularly preferred that the at least one securing device is arranged so that it is 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 offset, from the receiving holes. In particular, the tool holder base insert is designed such that when the tool holder base insert is arranged in the positioning position, the securing device is elastically deflected relative to the hook device against the insertion direction and in particular is inevitably in the unlocking position. The transition of the securing device into the securing position can only take place after the tool holder base insert has been transferred to the fixing position.

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

In a particularly preferred implementation of the invention, the securing device is designed as a web section, wherein the web section can be supported in a form-fitting manner with one web end against the direction of loading on the plate edge area. The fixing position of the tool holder base insert is thus determined on the one hand by the web end against the direction of loading and on the other hand by the contact surface of the hook leg in the direction of loading. Optionally, it can also be provided that the web section can also be supported with the other web end in the direction of loading on the plate edge area. However, since this can lead to an overdefinition of the tool holder base insert, it is more preferred that the web end is set back slightly in relation to the contact surface in the direction of loading.

It is particularly preferred that the securing device and one of the hook devices are arranged in a common receiving hole in the assembled state of the tool holder base insert and/or in the fixing position. Alternatively or additionally, the securing device and the hook device are positioned in the adjustment hole grid in a common receiving hole. This positioning has the advantage that the positive support on both sides of the securing device, in particular the web end, and the hook leg, in particular the contact surface, within a very small area, so that no tilting or other disturbances can occur. Furthermore, the number of mounting holes required 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 one another on the perforated grid plate, since no separate mounting hole has to be kept free for the securing device.

One aspect relates to a method for mounting the at least one tool holder base insert on the breadboard of the tool holder assembly.

The method includes placing the tool holder base insert on the perforated grid plate in the positioning position, wherein the at least one hook device with the hook head is inserted into a receiving hole in the perforated grid plate. The at least one securing device, on the other hand, stands on the perforated grid plate. In a subsequent step, the securing device is deflected into the unlocking position, which can be implemented, for example, by a pressure load on the base body section, in particular on the first operating area, wherein the hook heads dip further into the receiving holes, but the securing device rests positively on the front of the perforated grid plate. In a subsequent step, the tool holder base insert is displaced relative to the perforated grid plate in the assembly direction so that the plate edge regions of the plate body of the perforated grid plate can move into the plate receiving regions of the hook devices. This sliding movement can be supported by the control bevel or bevels of the securing elements, since these slide along the edge regions of the perforated plate grid when inserted or dipped in, thereby displacing the tool holder base insert in the assembly direction. In a subsequent step, the securing devices snap into the receiving holes and move into the securing position, so that the tool holder base insert is in the fixing position in the perforated grid plate in the assembled state. When the tool holder base insert is released, the securing section is manually lifted so that the securing device is transferred from the securing position to the unlocking position. The tool holder base insert is then transferred from the fixing position to the positioning position and can be removed from the perforated grid plate. The securing section particularly preferably has a second operating area for manual lifting, wherein the second operating area is arranged such that the tool holder base insert is pushed or at least loaded in the disassembly direction. Both the assembly and disassembly of the tool holder base insert can be carried out with a simple hand movement.

In one possible implementation of the invention, the tool holder base insert is designed as a base tool holder base insert, wherein this has at least or exactly four hook devices and 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 2x2 matrix. Particularly preferably, the two securing devices are arranged in a clamp-like manner around two of the hook devices within a row, preferably around the two hook devices that are at the bottom in the loading direction. It is also preferred that the pivot axis is arranged between, in particular centrally between, the two rows of the 2x2 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 comprises at least or exactly one securing device. It is particularly preferably provided that the hook devices are arranged one above the other in the loading direction and that the securing device is positioned next to the lower hook device in the loading direction.

It is particularly preferred that the mounting direction for the tool holder base insert and for the tool holder device is aligned, parallel or identical and optionally additionally aligned, parallel or identical to 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 further tool holder device, wherein the plug-in interface is designed, for example, as a through-opening. For example, the through-opening can have a circular cross-section so that a round material, such as a rod, can be inserted.

A further subject matter relates to the use of the tool holder device as described above in the tool holder arrangement as described above, in particular for sliding onto at least one of the tool holder base inserts and/or for holding at least one tool.

The 1 shows a schematic three-dimensional representation of a tool holder arrangement 1 as a first embodiment of the invention. The tool holder arrangement 1 can be designed, for example, as a workshop trolley, with further components of the workshop trolley in the 1 are suppressed in the drawing.

The tool holder arrangement 1 comprises a perforated grid plate 2 and a tool holder base insert 3, which is arranged on or in the perforated grid plate 2 and is firmly connected thereto.

The perforated grid plate 2 is designed as a plate body, in particular as a sheet, specifically as a metal sheet, and has a plurality of receiving holes 4. The receiving holes 4 are square in plan view and have a size of 9.2 millimeters x 9.2 millimeters, for example. The receiving holes 4 are distributed in a grid which has a transverse direction Q and a longitudinal direction L, wherein the distance between the individual receiving holes 4 in the transverse direction Q or in the longitudinal direction L is 38.1 millimeters each. The plate body has a thickness of less than 2 millimeters, for example.

The tool holder base insert 3 is designed as a one-piece plastic injection molded part and can be divided into two different sections as part of its function. A base body section 5 is T-shaped in plan view from the front, with the transverse or transversely extending leg of the "T" extending in the longitudinal direction L to approximately 50 percent of the total length of the tool holder base insert 3. The tool holder base insert 3 also has a securing section 6 which is U-shaped. The U-shaped securing section 6 is open to the base body section 5 and encompasses the standing leg of the T-shaped base body section 5. In particular, the securing section 6 forms a securing bracket. The free ends of the U-shaped securing section 6 are molded onto the transverse leg of the T-shaped base body section 5, with the transition between the securing section 6 and the base body section 5 forming a pivot joint 7 which defines a pivot axis S. The pivot axis S is aligned parallel to the perforated grid plate 2 and is also located approximately in the middle in the direction of the longitudinal extension L of the tool holder base insert 3. The area of the base body section 5 encompassed by the U-shaped securing section 6 forms a first operating area 19, which has a ribbing or other friction-increasing structure for easy identification by a user. When assembling the tool holder base insert, the user presses on the first operating area 19.

By gripping the lying leg of the U-shaped securing section 6, the securing section 6 can be pivoted about the pivot axis S and deflected relative to the base body section 5. To facilitate gripping, the securing section 6 can have a recess as a second operating area 20. The tool holder base insert 3 is rectangular to square in plan view. The surface extension is dimensioned such that a further tool holder base insert 3 can be mounted directly next to the tool holder base insert 3 in the adjacent receiving holes 4 without any rows or gaps between them.

The 2 shows a schematic side view of the tool holder base insert 3, wherein it can be seen that this has hook devices 8, which are arranged offset in height from one another in an assembly direction M. Although only two hook devices 8 can be seen in the view shown, the tool holder base insert 3 has two hook devices 8 in the 1 The exemplary embodiment shown has four hook devices 8 which are arranged in a 2x2 matrix to match the grid dimensions of the perforated grid plate 2. The hook devices 8 each have a plate receiving area 9 into which a plate edge area of the perforated grid plate 2 can be introduced, the plate edge area coming into positive contact with a contact surface 10 against a loading direction B. As a result, the tool holder base insert 3 is held in a positive fit in the loading direction B via the hook device 8. The tool holder base insert 3, in particular the base body section 5, rests with a support surface 11 in the assembled state or in the fixing position on the front of the perforated grid plate 2 in a positive fit. The hook devices 8 extend perpendicular or approximately perpendicular to the support surface 11. The contact surfaces 10 are aligned perpendicular or essentially perpendicular to the support surface 11.

The hook devices 8 can each be divided into a hook leg 12 and a hook head 13, with their longitudinal extensions being arranged perpendicular to one another. The hook leg 12 extends perpendicularly or approximately perpendicularly to the support surface 11, the hook head 13 extends perpendicularly or essentially perpendicularly to the hook leg 12 and/or parallel or essentially parallel to the support surface 11. In the side view shown, the hook leg 12 and the hook head 13 form an L-shape and form the plate receiving area 9.

Furthermore, in the side view in the 2 a safety device 14 can be seen, which is designed as a web section that is molded onto the safety section 6. The safety device 14, in particular the web section, extends in the assembly direction M and/or loading direction B and/or in the longitudinal direction L of the perforated grid plate 2. One end of the web section is designed as a control slope 21, the function of which is related to the 4 a - d is explained. The hook devices 8 and the securing devices 14 together form a plate interface for fastening the tool holder base insert 3 to the perforated grid plate 2.

In the 3 a schematic three-dimensional representation of the rear side of the tool holder base insert 3 is shown. For orientation, reference is again made to the T-shaped base body section 5 and the U-shaped securing section 6, which are movably connected to one another via the pivot joint 7. The hook devices 8 are molded onto the base body section 5. The support surface 11 is formed by various structures, such as webs, etc. on the base body section 5, so that the base body section 5 defines the support surface 11. In contrast, the two securing devices 14 are molded onto the securing section 6, so that when the securing section 6 is pivoted via the pivot joint 7 about the pivot axis S, they can be deflected relative to the adjacent hook devices 8 in a direction perpendicular to the surface extension of the perforated grid plate 2 and/or the support surface 11. It can also be seen in the illustration that the securing devices 14 are arranged adjacent to the hook devices 8 in the lower row, but are shifted or offset in the longitudinal extension L relative to them.

In the 4a A schematic sectional view is shown to describe the assembly of the tool holder base insert 3 on or in the perforated grid plate 2. The perforated grid plate 2 is in the 4a shown three times, with the perforated grid plate 2 being designated here as 2a, b, c. The perforated grid plate 2a is arranged at a distance from the tool holder base insert 3 in an insertion direction E, which is oriented perpendicular to the surface extension of the perforated grid plate 2a, b, c and/or perpendicular to the support surface 11. This relative positioning is also shown in the 4b shown.

The perforated grid plate 2b is positioned so that the tool holder base insert 3 is in a positioning position. In the positioning position, the hook heads 13 of the hook devices 8 are already immersed in the receiving holes 4 of the perforated grid plate 2. In the adjustment position of the tool holder base insert 3, the securing devices gen 14, however, at the front of the perforated grid plate 2b. This relative position is in the 4c shown.

If we consider the 5 , which shows a rear view of the tool holder arrangement 1, wherein the tool holder base insert 3 is in the adjustment position, it can be seen that the hook heads 13 are received in a form-fitting manner in the longitudinal direction and transverse direction by the perforated grid plate 2b. The perforated grid plate 2b defines a positioning hole grid relative to the tool holder base insert 3.

By loading the base body section 5 in the area of the standing leg on the first operating area 19 according to arrow A in the insertion direction E, the hook devices 8 of the lower row and also the hook devices 8 of the upper row are guided further through the receiving holes 4, wherein at the same time the securing devices 14 are deflected relative to the lower row of hook devices 8 and/or relative to the adjacent hook devices 8 against the insertion direction E. As soon as the hook heads 13 are immersed so deeply in the receiving holes 4 that the rear side of the perforated grid plate 2b can move into the receiving areas 9, the tool holder base insert 3 can be moved in the assembly direction M and/or later loading direction B relative to the perforated grid plate 2b, so that the tool holder base insert 3 is transferred to a fixing position. In particular, the insertion movement takes place strictly and/or exclusively parallel to the front side of the perforated grid plate 2 or 2a, b, c. During the transfer to the fixing position, the securing device 14 slides over the front of the perforated grid plate 2b. As soon as the control bevel 21 reaches the edge area of the receiving hole 4, the securing device 14 can slide into the receiving hole 4. The control bevel 21 pushes the tool holder base insert 3 further in the assembly direction M, since this converts a translation of the pressure application in the direction E and/or perpendicular to the perforated grid plate 2 into a translational movement in the assembly direction M.

The fixing position of the tool holder base insert 3 is relative to the perforated grid plate 2c or in the 4d shown. In the fixing position, the hook devices 13 are supported in the loading direction B via the contact surfaces 10 of the hook legs 12 in a form-fitting manner on the edge areas of the perforated grid plate 2c. Due to the offset of the tool holder base insert 3 relative to the perforated grid plate 2b, the securing devices 14 are now aligned with the receiving holes 4 so that they can be inserted into the receiving holes 4 in the insertion direction E. The hook heads 13, on the other hand, extend over the edge areas of the plate.

This situation is again in the 6 presented, whereby in the summary of the 4 and 6 It can be seen that the securing devices 14 are supported via one end, in particular the web end, in a form-fitting manner on the plate edge areas against the assembly direction M and/or the load direction B. The tool holder base insert 3 is thus arranged in a form-fitting manner in the perforated grid plate 2c both in and against the load direction B and/or assembly direction M. The tool holder base insert 3 is secured against removal against the insertion direction E by the overlapping hook heads 13 and the plate edge areas of the perforated grid plate 2c received in the receiving areas 9. The tool holder base insert 3 is thus secured in a form-fitting manner in every direction of movement.

When the tool holder base insert 3 is disassembled, the securing section 6 is pivoted relative to the base body section 5 about the pivot joint 7 by pulling on the second operating area 20, so that the securing device 14 is pulled out of the receiving hole 4. The pulling movement on the second operating area 20 places pressure on the tool holder base insert 3 against the assembly direction, i.e. in a disassembly direction, so that the tool holder base insert 3 can be removed from the perforated grid plate 2 in one overall movement. This is achieved by the pulling movement being directed in the opposite direction to the direction of extension of the hook heads 13 on the hook devices 8.

The position of the hole grid plate 2c relative to the tool holder base insert 3 defines a fixing hole grid, wherein the fixing hole grid is arranged offset from the positioning hole grid in relation to the tool holder base insert 3 in the mounting direction M.

As can be seen in particular from the 6 , the hook devices 8 of the upper row are designed as wide hook devices 8, which are also supported in the transverse direction Q on the plate edge sections of the receiving holes 4. In contrast, the hook devices 8 in the lower row are designed as narrow hook devices 8, which are supported in a form-fitting manner on the plate edge areas only on one side of the transverse direction Q. On the opposite side, however, one of the securing devices 14 is arranged in the same receiving hole 4. Because both a securing device 14 and a hook device 8 are arranged in a common receiving hole 4, the tilting and similar disturbances that could occur if these components are arranged in different receiving holes 4 are minimized.

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

Furthermore, the tool holder base insert 3 has rail sections 16 a, b on the transverse leg of the T-shaped base body section 5, which run in the longitudinal direction L on the edge side and onto which an attachment body, such as one of the tool holding devices 18 described below, can be pushed so that they form a common sliding interface.

The one in the 1 to 6 The tool holder base insert 3 shown is square or nearly square and shows a 2x2 matrix of hook devices 8. This can be referred to as a basic tool holder base insert.

In the 7 and 8th a tool holder base insert 3 is shown as a supplementary tool holder base insert in the front view and in the rear view, whereby this only has two hook devices 8, which are arranged one above the other in a 2x1 matrix. The tool holder base insert 3 has exactly one securing device 14, which can, however, be inserted together with the lower hook device 8 into a common receiving hole 4. The tool holder base insert 3 designed as a supplementary tool holder base insert also has a T-shaped base body section 5 and a U-shaped securing section 6, so that the function is referred to in the previous description.

The round material is made of metal, in particular of an aluminum alloy.

• XIII - XV: Supplementary tool holder base insert with a clamping device made of plastic as tool holding device 18, wherein the clamping device has several plastic bolts which engage in the through openings 17.

In the 9b various tool holder inserts 3 are shown when using the rail sections 16 a, b for sliding on tool holder devices 18. For illustration, the 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 can be pushed onto the rail interface of the tool holder base insert 3, designed as rail sections 16 a, b, from above in the loading direction B and which engages around the tool holder base insert 3 in a form-fitting manner. The tool holder device 18 can have different holding elements, with hook elements being shown in examples XVI and XVII. In examples XVIII-XXI, sorting boxes for tool inserts or for other small parts are shown as tool holder device 18. While the tool holder device 18 designed as sliding caps in examples XVI - XIX are only pushed onto a single tool holder base insert 3, the tool holder device 18 of examples XX and XXI is pushed onto two tool holder inserts 3, which are also arranged offset from one another.

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

The tool holder device 18, more precisely the slider holder 22, has two rail wing sections 24a, b, which extend in the assembly direction M and in the loading direction B, respectively. The rail sections 16 a, b ( 3 ) each have a sliding surface 25a, b, whereas the rail wing sections 24a, b each have a counter sliding surface 26a, b. The sliding surfaces 25a, b face the perforated grid plate 2 in the assembled state, whereas the counter sliding surfaces 26a, b face away from the perforated grid plate 2. In particular, the rail wing sections 24a, b engage behind 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 are located between the perforated grid plate 2 and the rail sections 16a, b or the sliding surfaces 25a, b.

The tool holder base insert 3 further comprises a guide surface 27, which is formed by the front side of the tool holder base insert 3. In contrast, the tool holder device 18 comprises a counter-guide surface 28, which is arranged in the slider receptacle 22 and faces the tool holder base insert 3 such that when the tool holder device 18 is mounted on the tool holder base insert 3, the counter-guide surface 28 can slide along the guide surface 27. The counter-guide surface 28 can be formed continuously, or - as in the 10a , b shown - can only be realized as ribs running in the mounting direction M.

The slider holder 22 forms a hood, the end of the hood being formed by a support area 29 to which the free end of the tool holder base insert 3, in particular the slider section 23, is attached with a support area 30 ( 3 ) in a form-fitting manner. In particular, the support area 30 forms an end stop for the support area 29 in the assembly direction M and/or in the loading direction B.

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

With the aim of preventing the tool holder device 18 from accidentally being detached from the tool holder base insert 3, the tool holder device 18 has two locking devices 32a, b, which are designed as locking hooks and which engage in locking receptacles 33a, b of the tool holder base insert 3. The locking devices 32a, b each form a locking interface with the locking receptacles 33a, b, which releasably secures the tool holder device 18 with the tool holder base insert 3 against the assembly direction.

The 11 a , b, c show three states during the sliding of the tool holder device 18 onto the tool holder base insert 3 along or parallel to the mounting direction M. By sliding on, a mounting plane ME is simultaneously defined, which is parallel or parallel to the mounting direction M. Furthermore, the mounting plane ME is aligned parallel or parallel to the front of the perforated grid plate 2. In the 11 a the tool holder base insert 3 is positively caught between the counter guide surface 28 and the counter sliding surfaces 26a, b and is thus centered in the sliding movement. The play in the direction perpendicular to the mounting plane is large, so that the tool holder device 18 can be easily placed on the tool holder base insert 3.

In the 11b the tool holder device 18 is pushed so far onto the tool holder base insert 3 that the free end of the tool holder base insert 3 is already gripped by the guide wing 31 and thus further centers the movement.

When the tool holder device 18 is pushed further onto the tool holder base insert 3, the locking devices 32a, b are locked into the locking receptacles 33a, b and the connection state is achieved. The counter-guide surface 28 and the counter-sliding surfaces 26a, b hold the tool holder base insert 3 via the guide surface 27 and the sliding surfaces 25a, b without play, almost without play or even with a certain pre-tension. By engaging the rail wing sections 24a, b behind the rail sections 23, the tool holder device 18 is positively secured in a direction perpendicular to the surface extension of the perforated grid plate 2 and/or the mounting plane.

The sliding surfaces 25a, b, counter sliding surfaces 26a, b, guide surface 27 and counter guide surface 28 can be dimensioned such that in the 11 a - c shown transition, the play in the direction perpendicular to the mounting plane and/or the centering becomes steadily narrower, so that a constriction occurs from a rough fit to a preloaded state.

In the 12 In this case, the tool holder device 18 is designed as a pliers holder device in a three-dimensional representation shown obliquely from the front in a detailed view. The tool holder device 18 designed as a pliers holder device has two receptacles 34a, b, the receiving direction of which is aligned vertically and forms a receiving channel for a first leg of a pair of pliers. Two pliers can therefore be inserted in parallel in the tool holder device 18 shown. It should be emphasized that two cheek sections 35a, b are arranged on the edge of the tool holder device 18, which extend in the surface extension approximately perpendicular to the perforated grid plate 2 and/or to the mounting plane and form a lateral boundary for the second leg of the pliers. Together with the boundaries of the receptacles 34a, b, the cheek sections 35a, b form a U-shaped area for the second legs of the pliers. When the pliers are inserted, the first leg of the pliers is thus captured by the holder 34a, b and the second leg of the pliers is guided laterally by the cheek sections 35a, b, so that the pliers cannot swing or oscillate in an uncontrolled manner. In particular, this ensures that the installation space for accommodating the pliers is limited to the extent in the transverse direction Q of the tool holder device 18.

It is pointed out that the tool holding inserts 3 in the design as basic tool holder base insert or supplementary tool holder base insert for the tool holding devices 18 in the 9a and 9b are each constructed identically. In particular, these can each be manufactured in one tool and thus form a highly functional module mounting plate for the tool holding arrangement 1.
