Description

Technical Field

[0001] The invention relates to a tool supply device, in particular a workshop trolley, a workbench or a tool cabinet, according to the features of the preamble to claim 1 . Background Art

[0002] Tool supply devices are known in various embodiments. Workshop trolleys, workbenches or tool cabinets are widely used. A common type of workshop trolley has a housing that can be moved by means of rollers, in which a number of containers in the form of drawers are arranged one above the other. The drawers are usually supported on side rails and pulled out of the housing at the front. Workbenches also have a housing with drawers arranged therein.

[0003] Tool providing devices have proven to be feasible in practice. The tool providing devices are used to receive and / or transport various tools, which can be stored in a storage system (Ordnungssystem). Different systems are known within its scope, which should be able to realize the identification and detection of tools and the uninterrupted registration of the tool removal and return process. DE 10 2007 017 207 A1 proposes in this case that each tool is equipped with a fixed storage space and a transponder, which can be coupled with a receiver arranged at the storage space for exchanging signals. As a result, it should be possible to continuously and permanently check whether the tool is in position or in operation. In addition, transponders should be configured for all authorized tool users and the tool storage device can only be accessed by means of transponders.

[0004] According to EP 1 663 586 B1, an inventory monitoring system for monitoring the removal and return of tools belongs to the prior art. Each tool storage location has a uniquely designed recess for receiving a specific tool, wherein the structure of the recess is adapted to the structure of the tool. In addition, a detection mechanism for detecting the presence of the tool and a mechanism for transmitting a signal from the detection mechanism to a data processing device are provided. The data processing device receives the signal of the detection mechanism and records the removal and return of the tool. The presence and / or absence of the tool is displayed via an output device.

[0005] EP 1 808 275 A2 also discloses a tool supply device comprising a tool holder having a recess for receiving a tool, in particular a hand-held tool. A sensor unit is arranged on the side of the tool holder opposite the tool-side recess. The sensor unit is intended to detect the presence and / or absence of a tool through the tool holder.

[0006] DE 10 2008 031 372 A1 also describes a method and a system for monitoring the presence of a tool at a predetermined location.

[0007] US 2009 / 0072029 A1 discloses an inventory checking system for a tool providing device, comprising a plurality of storage locations for inventory items, in particular receptacles for tools, and a monitoring system for monitoring the removal and insertion of tools from and into the receptacles.

[0008] Furthermore, AT 13969 U1 discloses a tool output device in which a certain space is assigned to each tool. Each space is assigned a sensor which is connected to an evaluation device and via which the presence or absence of the tool to be output is evaluated.

[0009] US 2010 / 0039513 A1 describes a system for monitoring the inventory status of objects, in particular tools in a drawer of a tool supply device, based on detected images.

[0010] US Pat. No. 7,317,393 B2 discloses a system for tracking and checking the access to and from objects. The system comprises a storage unit in the form of a closable cabinet for storing, discharging and receiving objects. A computer control device is coupled to the cabinet and has a user interface for identifying or authenticating a user. In addition, the removal and return of objects are monitored by means of the computer control device.

[0011] The reliability of tool detection is worth improving in practice. In particular, contactless tool detection and data transmission within the system have their limitations. Checking the integrity of tools before and after work in sensitive areas, such as assembly-, maintenance- and / or repair work on aircraft, is of particular significance. Lost tools can cause significant damage to aircraft. Within the scope of measures against foreign object damage (FOD), it is necessary to carry out a particularly effective check of the integrity of the tools and to track them in order to avoid damage. Summary of the invention

[0012] Starting from this prior art, the object of the present invention is to improve a tool providing device including a tool identification and monitoring device in a simple design with regard to its reliability and its usability overall.

[0013] According to the invention, this object is achieved by a tool providing device according to the features of claim 1 .

[0014] Advantageous embodiments and developments of the tool providing device according to the invention are the subject matter of the dependent claims.

[0015] The description and the drawings also provide configurations and modifications of features of the tool providing device which, individually or in combination, advantageously configure the tool providing device in terms of functionality and application technology.

[0016] The tool supply device according to the invention is in particular a workshop trolley, a workbench or a tool cabinet. The tool supply device has a housing and a container arranged therein, wherein at least one tool rack is arranged in the container, the tool rack having a plurality of receptacles for tools. The receptacles are each provided with a detector for detecting the presence of a tool in the receptacle. In particular, the container is a drawer or a drawer.

[0017] According to the invention, the detector has a key switch with a key element, wherein the key element passes through an opening in the tool holder and projects with an active surface into a receptacle for a tool. In particular, the active surface can be arranged on the end side of the key element, but can also be arranged on the side of the key element or can be formed by it. It is important that the active surface projects into the receptacle so that the key switch is activated by an inserted tool and is deactivated when the tool is removed.

[0018] Furthermore, the invention provides that there is a first type of receiving part, wherein the opening is a notch through the wall of the tool holder below the receiving part, wherein the key element protrudes from below through the bottom of the receiving part into the receiving part. Furthermore, there is a second type of receiving part, wherein the key element protrudes laterally into the receiving part, i.e. from the side wall. In particular, the opening for the key element is a notch or cutout through the wall of the tool holder laterally of the receiving part. Furthermore, the invention provides that a retaining element is arranged in at least one receiving part, which retaining element acts as a pressure intensifier for the tool.

[0019] The difference between the first type of receiving part and the second type of receiving part in the tool holder is the arrangement structure and design of the notch for the key element. In the first type of receiving part, the opening for the key element is a notch that passes through the wall of the tool holder below the receiving part. The key element is guided from below through the bottom of the receiving part and protrudes into the receiving part. When the tool is inserted, the key element moves vertically and is pressed downward by the weight. When the corresponding tool is taken out, the key element moves upward or upward.

[0020] The first type of receptacle is provided, in particular, for a hand-held tool such as a torque wrench, a hammer or pliers.

[0021] In the second type of tool receptacle, the opening for the key element is a notch that penetrates the wall of the tool holder at the side of the receptacle. The notch can extend from the bottom of the tool receptacle to the side wall of the receptacle. The key element protrudes laterally through the wall of the tool holder into the receptacle and laterally contacts the inserted tool. In this case, the key element rests on a section of the tool that extends adjacent to the side wall of the receptacle and substantially parallel thereto.

[0022] The receptacle of the second type is provided, in particular, for a tool such as a socket head, a socket wrench or an insert or a screwdriver bit.

[0023] The pushbutton switch is a detection element that is activated by pressing on its pushbutton element and deactivated again by releasing it. In this way, it is possible to detect whether a tool is present or absent in the receptacle. The weight of the tool in the receptacle presses the pushbutton element of the pushbutton switch and activates the pushbutton switch. By means of the pressure, the pushbutton switch establishes a connection that is interrupted again when the pushbutton switch is released, i.e. when the tool is removed. The pushbutton switch assumes its initial position again by means of a spring that is integrated in the pushbutton switch and acts on the pushbutton element.

[0024] The position of the key element extending into the receiving portion is the initial position of the key switch, and the position of the key element lowered or pressed by the tool is the triggering position of the key switch, whereby a signal is generated and transmitted to the data processing unit.

[0025] In the first type of receiving part, the tool abuts against the active surface of the key element protruding through the bottom of the receiving part and presses the key element downward. In the second type of receiving part, the inserted tool abuts against the active surface of the key element protruding in the receiving part through the notch in the side wall and presses or pushes the key element to the side.

[0026] The invention is suitable for electromechanically detecting a tool in a receptacle, wherein the detector or a pushbutton switch of the detector is in contact with the tool and is activated directly by the tool itself.

[0027] The detection of the presence of a tool works reliably. Interfering influences are hardly significant. Thus, for example, a contaminated tool does not affect the effectiveness of the detection. No manual marking or sensor marking is required on the tool itself.

[0028] An advantageous embodiment of the key element provides that the key element is a tappet, in particular a spring-loaded tappet, or a leg, in particular a spring leg, or a lever, in particular a spring lever.

[0029] The button element, ie, for example, the contact pin, can have a surface contour that is determined and adapted to the tool style so that the position of the tool can be better sensed. For example, the surface contour can be coordinated with an angle screwdriver or a hexagonal Allen key.

[0030] Another advantageous aspect of the present invention provides that the at least one key switch is arranged in a carrier. Preferably, a plurality of key switches are advantageously arranged in a row in the carrier and positioned on a printed circuit board. The printed circuit board including the key switches is received in the carrier and arranged on the tool holder with the carrier. The arrangement is carried out in the design according to the present invention so that each key element of the key switch passes through an opening in the tool holder and protrudes into the receiving portion with its active surface. The carrier can form a component of the tool holder. In particular, in the second type of receiving portion, a part of the carrier forms a side surface of the second type of receiving portion.

[0031] The opening in the first type of receiving part is a notch that penetrates the wall of the tool holder in the area below the receiving part. The opening is coordinated with the size of the key element of the key switch so that the key switch can be easily moved back and forth in the opening. The tool holder itself is particularly preferably formed by a soft foam lining. Preferably, the receiving part has a recess in the tool holder that is adapted to the structure of a specific tool.

[0032] In the second type of receiving part, the opening is a notch that penetrates the wall of the tool holder at the side of the receiving part or a lateral cutout in the tool holder. The key element is implemented as a lever leg or spring leg, especially a spring-loaded lever, and protrudes laterally into the receiving part.

[0033] The receiving part in the tool rack can be equipped with identification features for the respective tools. This can be a mark, such as a tool product number, but can also be a symbol or a pictogram. With the help of the identification feature, the tool can be easily and quickly equipped with the receiving part.

[0034] According to the invention, a combination of multiple key switches is advantageous, wherein a key switch is provided, the key element of which protrudes into the receiving part from below, that is, through the bottom of the receiving part, and a detector is also provided, which includes a key switch, the key element of which protrudes laterally into the receiving part, that is, the key element extends with its active surface through an opening in the form of a through-portion in the side wall of the receiving part of the tool holder.

[0035] One aspect of the invention provides that the key switch is at least indirectly supported on the bottom of the container, in particular the drawer. This is advantageous for the force introduction, sensitivity and triggering of the detector. One or more key switches can be arranged in a carrier or received in a carrier. Via the carrier, the key switch is indirectly supported on the bottom of the container. In addition, the carrier can be at least indirectly supported on the bottom of the container.

[0036] An advantageous embodiment provides that the key element or the key switch comprising the key element is integrated in a housing. The housing forms a carrier for the key element and improves functional safety. Advantageously, the housing is mounted directly on the circuit board with integrated contact pins. In particular, the housing ensures the functionality and mechanical mobility of the key element.

[0037] A particularly advantageous design for practical purposes provides that the key switch is fastened to a circuit board which is arranged on the bottom of the container below the tool holder. The tool holder has a plurality of receptacles, wherein each receptacle is assigned a detector. Advantageously, in this case all detectors are arranged in one horizontal plane. This increases the reliability and availability of the detectors and integrates a plurality of detectors in one detector plane. Another advantage is that the key element, like the circuit board, does not require additional space in the container or only requires insignificantly more space, since the component is essentially positioned in or below the tool holder, in particular in a tool holder formed by a soft foam lining.

[0038] In particular, the pushbutton switch of the detector is triggered or activated by the weight of the tool in a weight-loaded manner. If the weight of the tool itself is not enough, the present invention stipulates that a retainer element, in particular a clip-shaped retainer element or a magnetic retainer element, i.e. a magnet retainer element, is arranged in at least one receiving portion. The retainer element is determined and designed to be used for the tool to be loaded into the receiving portion by means of a determined force consumption. Through this force consumption, the pushbutton switch is operated via the tool. The retainer element acts as a compression enhancer of the tool in the receiving portion. The retainer element holds the tool in the receiving portion and ensures that the pushbutton switch remains in the trigger position as long as the tool is arranged in the receiving portion. By strengthening the compression of the tool by means of the retaining element, the tool is fixed in the receiving portion.

[0039] In particular, in the case of light tools, a retainer element in the form of a magnet retainer is integrated in the receptacle to press the tool onto the key switch in position. This is also advantageous in the case of vibrations and / or movements of the tool supply device, such as a workshop trolley.

[0040] The arrangement or number of the receptacles including the integrated holding element, which acts as a clamping intensifier for the tool, is coordinated with the equipment, geometry and / or weight of the tool to be received in the container or drawer. The same applies to the first type of receptacle and the second type of receptacle.

[0041] A data processing unit is provided for detecting and evaluating the signals generated by the one or more detectors and for further processing thereof. The data processing unit is designed and configured to receive signals from the one or more detectors and to record and archive the removal and return of the tool.

[0042] The tool is identified by means of a data processing unit. This is achieved by evaluating and processing the signals received by the detector and assigning them to a receiver in the tool holder.

[0043] Furthermore, tool usage data, such as output duration or output time, but also test intervals of the tool or its calibration and / or tool status data and tool user data can be detected by means of the data processing unit.

[0044] When the tool is taken out of the receiving part of the tool rack, as when the tool is returned to the receiving part, a signal is generated by the displacement of the key element by the detector configured to the corresponding receiving part via the key switch. These signals are registered via the software and electronic components forming the data processing unit. The absence and presence of the tool are transmitted to the analysis and processing unit, and in particular, the information can be displayed on the wirelessly connected instrument. This not only acts as an independent working solution (Einzelplatzlösung) for a tool providing device, but also as a server solution for an overview of all connected tool providing devices, especially multiple workshop carts, workbenches or stationary tool cabinets. The tool can be identified, and for the tool, in addition to the usual information, such as tool type and age, other information, such as test-, inspection-, or calibration intervals or usage time, can also be stored.

[0045] The tool inventory is monitored and managed automatically. The tools are automatically and immediately recorded in inventory in the tool provision device. Access checks and traceability are simplified. The identification and management of tools are carried out in real time. User identification at the tool provision device can be achieved through personalized access credentials or personal codes. The following system software belongs to the identification and management system, which is activated when the tool provision device is used. Tools can be taken out by the user or returned after use. The removal or return is stored. The associated use process or time is obtained and archived. Automatic inventory recording can be carried out when closing each drawer or during the locking process of the tool provision device.

[0046] An advantageous embodiment provides that the outline of one or more tools is present on the circuit board. The outline appears to the observer as a curve that separates the object from its surroundings. This measure facilitates the equipment of the circuit board itself but also the arrangement of the tool holder in the drawer on the circuit board.

[0047] Of course, within the scope of the invention it is also possible to use circuit boards in which the contour of the tool is not present on the surface of the circuit board.

[0048] Preferably, a plurality of circuit boards are arranged side by side on the bottom of the drawer. In this case, it is suitable that each circuit board has a module size adapted to the size of the container so that the circuit boards cover the bottom surface together. In particular, two, three or four circuit boards are arranged side by side on the bottom surface of the container.

[0049] Measures to further increase the usability of the tool providing device provide that one or more cable carriers are arranged in the housing for the electrical connection wires. The cable carriers are used in particular to hold and guide the electrical connection wires between the circuit boards (in the container) and between the circuit boards and the data processing unit. The cable carriers enable the movement of the electrical connection wires, in particular when the drawer is pulled out and pushed back.

[0050] In practice, a plurality of movable cable carriers are arranged in the housing. These cable carriers carry energy supply lines and data communication lines to each individual container, in particular each individual drawer. Thus, each container is provided with a cable carrier.

[0051] Furthermore, a cable channel (especially in sheet metal construction), ie preferably a sheet metal component, is fixedly joined, especially welded, to the housing itself. During assembly, the individual movable cable carriers are screwed or riveted to this channel together with the electrical conductors, ie the cables.

[0052] Preferably, the cable arm of the cable carrier is fixed to the container with a releasable connecting element, such as a screw. This makes it easy to assemble and possibly replace the cable carrier or both.

[0053] Another advantageous aspect of the present invention provides a locking system, by means of which the container can be centrally locked in the housing. Preferably, the locking system can be operated from a central locking unit. In particular, a contactless opening or closing of the locking system can be achieved, for example, by means of a radio frequency identification (RFID) transponder. The electronic locking system preferably has an electric servomotor, by means of which the locking strip can be moved and the locking device can be transferred to an open or closed position. The operation is achieved via user identification, such as a personal identification code (PIN-Code) or an identification certificate. In this case, it can involve an RFID sensor or a transponder or a similar identification tag (mark). Tool user data can also be detected by means of a correspondingly designed transmitter-receiver system.

[0054] The locking system can also be automatically switched to the locked state by software control. This can be done, for example, in a time-controlled manner. For this purpose, a timing circuit is integrated so that the tool supply device automatically closes and switches to the locked state after a predetermined time interval, during which no use occurs.

[0055] The locking system of the tool providing device according to the invention has a mechanical emergency unlocking device, via which the locking device of the tool providing device can be actuated in the event of failure of the electronic locking system. In particular, the emergency unlocking device has a cylinder lock.

[0056] The tool providing device has functional electronics, wherein the functional electronics actuate at least one actuator. The actuator is provided, in particular, for actuating a locking strip of a locking system.

[0057] The functional electronics may also have a wireless communication module, which in this case is in particular a Bluetooth module or a WLAN module.

[0058] The wireless communication module is an integral component of the data processing unit. In this way, the tool providing device can provide a device-related WLAN network, which includes a wireless access point, that is, a wireless access point, which acts as an interface for wireless communication devices. In this way, the tool providing device can communicate with mobile devices, such as smartphones or smart tablets or other operating devices (operators). It is also possible to combine multiple tool providing devices in one network so that they can be monitored centrally or decentralized.

[0059] In this case, a particularly advantageous design provides that a display is provided which communicates with the data processing unit. Via the display, the presence or absence of a tool can be displayed, but also tool usage data and / or user data can be displayed. The display is preferably arranged or integrated in a functional area on the tool providing device. The display shows the status of the tool and / or the shutdown state of the tool providing device, for example the battery charge state. Information about peripheral components of the tool providing device, such as a data processing cable, in particular its presence or absence and possible operating modes, can also be detected and displayed via the data processing unit and the display.

[0060] The tool providing device is equipped with an electrical energy supply. The energy supply is preferably realized via a current storage device, in particular a lithium-ion battery. The battery can be mounted in an easily accessible holding device on the tool providing device. The holding device enables easy and fast replacement of the battery. In practice, the battery is preferably covered by an enclosing housing. The housing has a protective function in particular, but also achieves a visual improvement. In addition, the battery housing can be designed to be closable in order to prevent unauthorized access to the battery.

[0061] It is also advantageous if at least one signaling element is provided in or on the tool providing device, which is designed and configured to signal the presence or absence of a tool in the container. In particular, the signaling element is an optical signaling element, preferably in the form of a light element, such as a light emitting diode (LED). The signaling element can be arranged in a container, preferably in a soft foam lining of a drawer.

[0062] Acoustic signaling elements may also be used.

[0063] A particularly advantageous embodiment provides that the signal element or the signal unit having a plurality of signal elements is arranged in an edge protection element arranged on the housing. In particular, the edge protection element extends in the longitudinal direction of the side edge of the housing, and more precisely at the housing front side. A signal element, in particular an LED, is integrated at least in the edge protection element arranged laterally on the housing. Such an edge protection element acts as a collision protection device or an impact protection device and is made of an elastic material, in particular a plastic material. In order to receive the signal element or the signal unit comprising a plurality of signal elements, a recess is provided in the edge protection element. Preferably, the recess is horizontally at the same height as the upper edge of the container, in particular a drawer, and more precisely preferably at the same height as the drawer handle. Each signal unit therefore represents an adjacently arranged drawer and thereby represents the tools present in the corresponding drawer. Visually display of the tool inventory is achieved. A green signal shows that the tool equipment in the corresponding drawer is complete. A red signal shows that the tool set in the drawer is insufficient. This type of display is advantageous because the user can quickly and easily understand by means of a signal whether a tool is missing and in which drawer the tool is missing. The arrangement of the signal element or signal unit at the front adjacent to the corresponding drawer plane is clearly visible and can be clearly seen from the main working direction in front of the workshop trolley.

[0064] It is also possible that the signal element is arranged on the front face of a container, for example a drawer. In addition, the signal element can also be arranged inside a display or a functional area of ​​the tool providing device.

[0065] Via the visualization of at least one, preferably a plurality of, signaling elements, in particular in the form of optical indicator lights (LEDs), it is quickly indicated to the user whether all tools are present in the drawer. In this case, for example, signals of different colors can be generated. For example, red light indicates that a tool is missing, while for example blue or green light signals to the user that all tools are present. Preferably, LEDs with a color change function are used.

[0066] Within the scope of the invention, at least one signaling unit is provided, which is designed and defined to signal the shutdown state of the tool supply device and / or the battery charge state of the electrical energy supply unit and / or the integrity of the tools, i.e. the tool inventory. Such a signaling unit is arranged in particular at or in a handle area or a functional area on the housing of the tool supply device.

[0067] In the embodiment, the signal element, in particular the light emitting diode, is connected to the circuit board. The fixing is performed via a holding device, which carries the signal element and is screwed onto the circuit board. The holding device is in particular cylindrical and shell-shaped. When the signal element is arranged in a container, the holding device protrudes through the tool holder in the container. The holder reaches the surface of the tool holder through the opening in the tool holder with the integrated signal element, preferably the light emitting diode. In this way, the signal element is very noticeable to the user. The holding device with the integrated light emitting diode is also called LED dome (LED-Dom).

[0068] Another aspect of the present invention provides that at least one key switch including the integrated key element is designed and constructed to receive a plug-in element of a cable, such as a USB cable. For this purpose, the key switch has a plug-in opening. The key element is designed so that it is operated by introducing the plug-in element. For example, the key element has a correspondingly configured inclined surface so that the key element is pressed downward when the plug-in element is inserted and the key switch or key detector is triggered. In this way, the presence of electrical cables, especially data communication cables, in the tool providing device can be monitored and queried. Preferably, a receiving part in the tool holder is also provided for such cables, wherein the receiving part is configured with a correspondingly configured detector including a key switch and a key element.

[0069] According to a refinement of the tool providing device of the present invention, it is provided that at least one container, in particular a drawer, is equipped with a weighing system. The weighing system has a weighing unit and is determined and designed to determine the weight of the tools arranged in the container. The weighing system is correspondingly coupled to a functional electronic device, which is designed to compare the actual weight of the tools in the container with a theoretical weight. In this way, it is possible to check whether the tools are equipped and the integrity of the tools in at least one drawer via a weighing system instead and / or in addition. For this purpose, the actual weight of the tool rack is compared with the predetermined theoretical weight of the tool rack fully equipped with tools via the weighing system and in the event of a deviation, a missing report is displayed.

[0070] The weighing drawer or the weighing system integrated in the drawer and its functional electronics are coupled to a data processing unit and a signaling unit and a signaling element for visualizing the completeness of the equipment of the weighing drawer with tools. In particular, this is achieved via a signaling element of the signaling unit, which displays the corresponding equipment status as compliant or complete or non-compliant or incomplete. Preferably, for this purpose, the signaling element is arranged adjacent to the drawer in an edge protection element provided on the housing. BRIEF DESCRIPTION OF THE DRAWINGS

[0113] In the figures, identical or functionally corresponding components or component groups of the tool providing device and their parts are provided with the same reference numerals, even if a repeated description is omitted for the sake of simplicity.

[0114] Figure 1 A tool supply device is shown in the form of a workshop trolley 1. Such a workshop trolley 1 is used, for example, to receive and store tools in assembly or repair operations in the land, air or water transport industry.

[0115] The workshop trolley 1 has a cabinet-like or frame-like housing 3 supported on rollers 2, the housing comprising a cover plate 4. A handle 5 is provided on the housing at the narrow side of the workshop trolley 1 or housing 3, which is rectangular in horizontal cross section. The housing 3 forms the carrier body of the workshop trolley 1. In the housing 3, a certain number of containers in the form of drawers 6 are arranged vertically one above the other. The drawers 6 can be displaced on guides which are arranged on a drawer frame in the housing 3. Each drawer 6 can be locked in the housing 3 by a locking device.

[0116] The workshop trolley 1 with the drawer 6 pulled out from the housing 3 is Figure 2 . A tool rack 7 is arranged in the drawer 6. The tool rack 7 is formed by a soft foam lining. A receiving portion 8 for each tool 9 is provided in the tool rack 7 (see also Figure 3 , Figures 4 to 6 and Fig.10 ). The receiving portion 8 has a recess 10 in the tool rack 7 adapted to the structure of a specific tool 9. It is also possible to arrange a plurality of tool racks 7 in the drawer 6, which complement each other and cover the bottom of the drawer 6. See also Figure 7 .

[0117] The workshop trolley 1 is equipped with a tool identification and management system. The tool identification and management system enables automated monitoring and management of tool inventory. The tool identification and management system has a data management unit with peripheral instruments that receive, process and output data, that is, automatically performs the necessary data processing.

[0118] The tool racks 7 arranged in the drawers 6 each comprise a soft foam structure and have a plurality of receptacles 8 for different tools 9. In general, the receptacles are provided with reference numeral 8. There are receptacles 8a of a first type and receptacles 8b of a second type. Each receptacle 8, 8a, 8b is formed by a recess 10 in the tool rack 7 adapted to the structure of a particular tool 9. The recess 10 is formed by a depression in the soft foam lining of the tool rack 7. Each receptacle 8, 8a, 8b is provided with at least one detector 11, which detects the presence of a tool 9 in the receptacle 8, 8a, 8b.

[0119] The detector 11 has a key switch 12 with a key element 13 in the form of a spring-loaded tappet 13a. The key switch 12 is fastened to a circuit board 14 below the receiving portion 8, 8a, 8b, respectively ( Figure 7 and Fig.10), the circuit board is arranged below the tool rack 7 at the bottom of the drawer 6. In this way, the key switch 12 is indirectly supported on the bottom of the drawer 6. The key element 13 of the key switch 12 passes through the opening 15 in the tool rack 7. In the first type of receiving portion 8a, the opening 15 is a notch that passes through the wall of the tool rack 7 below the receiving portion 8a and is circular in cross section. The diameter of the opening 15 is measured so that the key element 13 or the tappet 13a is guided in the opening 15 and can be easily moved back and forth. The tappet 13 has a length greater than the wall thickness of the tool rack 7 below the receiving portion 8a, so that the tappet 13a protrudes into the receiving portion 8a through the bottom 42 of the receiving portion 8a with the action surface 16. The action surface 16 is constructed on the end side of the key element of the tappet or is formed by the end side of the tappet 13a. The key element 13 or the tappet 13a protrudes with its end side or with the action surface 16 relative to the bottom surface of the recess 10.

[0120] Each tool holder 7 has a plurality of receiving parts 8a and 8b, each of which is equipped with at least one detector 11. All detectors 11 are arranged in a horizontal plane and form a key area. The circuit board 14 is a support for the key switch 12 and is used for its mechanical fixation and for electrical connection. For this purpose, the circuit board 14 is equipped with corresponding conductive connecting parts and conductor circuits.

[0121] In order to facilitate the configuration of the tool rack 7 and to facilitate the installation of the circuit board 14 in the drawer 6 and the configuration of the tool rack 7, the contour 17 of the corresponding tool 9 is present on the circuit board 14. This is particularly true in Figure 4 and Figure 7 It can be seen in the figure. It can also be seen that a plurality of circuit boards 14 are arranged side by side on the bottom of the drawer 6. Each circuit board 14 has a module size adapted to the size of the drawer 6, so that these circuit boards 14 cover the bottom surface together. The individual circuit boards 14 are electrically conductively connected to each other. The connection to the data processing unit is established via an interface with the aid of electrical connecting wires. For this purpose, a cable carrier 25 is arranged in the housing 3 for electrical connecting wires, in particular for connecting wires between the circuit boards 14 and the data processing unit. The cable carrier 25 is Figures 4 to 6 The cable carrier 25 has two support arms 26, 27 which are connected to each other in a folding and articulated manner. The electrical connection wires are held and guided by the cable carrier 25 so that they can follow the movement without interference when the drawer 6 is pulled out and pushed in.

[0122] The key element 13 of the key switch 12 extends with its active surface 16 relative to the bottom 42 of the recess 10 so that it protrudes into the first type of receiving portion 8a. By inserting the tool 9 into the receiving portion 8a, the push rod 13a of the key switch 12 is pressed downward. A signal is thus generated and the presence of the tool 9 in the corresponding receiving portion 8a of the first type is recognized. The weight of the tool 9 in the receiving portion 8a presses the push rod 13 of the key switch 12 downward and activates the key switch. When the tool 9 is removed, the key element 13 is unloaded. The connection at the key switch 12 is interrupted. It is recognized by this signal that the tool 9 has been removed from the receiving portion 8 and is missing. Therefore, the key switch 12 is activated or deactivated by direct contact between the key element 13 and the tool 9.

[0123] In the case of a lighter tool 9, there is a pressing intensifier in the form of a retaining element 18 into the receiving portion 8. The retaining element 18 can be embodied as a clip-like retaining element. The retaining element 18 has a spring clip with spring legs arranged in the receiving portion 8. Such a retaining element 18 is particularly useful in Figure 7 . The tool 9 must be inserted into the receiving portion 8 here by means of a certain expenditure of force for overcoming the spring force of the retaining element 18. By means of this pressing, the associated push switch 12 is actuated by contact with the tool 9. The retaining element 18 holds the tool 9 securely in the receiving portion 8 and ensures that the push switch 12 remains in the triggering position. This is advantageous in the case of light tools 9, so that these tools can also be held in the receiving portion 8 under vibrations, for example during transportation on a workshop trolley 1.

[0124] Another embodiment of the retaining element 18 is magnetically active. The magnetically active magnetic retaining element is implemented as a permanent magnet and is placed in, below or to the side of the receiving part 8. By the magnetic force of the magnetic retaining element, the tool 9 is pulled into the receiving part 8 and the pressing against the push switch 12 is intensified and the tool 9 is fixed in the receiving part 8.

[0125] In the first type of receiving portion 8a, the opening 15 is a notch extending through the wall of the tool holder 7 below the receiving portion 8a. The key element 13 of the key switch 2, which is implemented as a tappet 13a, passes through the opening 15 from below through the bottom 42 of the receiving portion 8a and projects with its end-side active surface 16 relative to the bottom surface of the recess 10 and protrudes into the receiving portion 8a.

[0126] Furthermore, there is a second type of receiving part 8b (see also Fig. 20 and Fig.39). In the second type of receiving part 8b, the opening 15 is arranged laterally in the side wall 43 of the receiving part 8b. In the second type of receiving part 8b, the detector 11 has a key element 13 in the form of a lever 13b, which passes through the opening 15 in the tool holder 7, wherein the opening 15 is arranged on the side of the receiving part 8b. Fig.12 Such a design of a detector 11 is shown, which comprises a key switch 12 and a spring-loaded key element 13 arranged laterally. Such a key 12 has a key element 13 in the form of an articulated lever 13b or a spring leg. The key element 13 in the form of a lever 13b cooperates with a spring-loaded pin 23 of the key switch 12. For such a detector 11 or a key element 13b protruding laterally into the receptacle 8b, the opening 15 is designed as a notch, which penetrates the side wall 43 of the tool holder 7 laterally of the receptacle 8b.

[0127] exist Figures 13 to 16 It can also be seen that Fig.12 A plurality of key switches 12 are shown in FIG. Fig.13 and Fig.14 A plurality of pushbutton switches 12 arranged in a row are shown, which are arranged in a carrier 24 or received in a carrier 24. Fig.13 and Fig.14 It can be seen that including Figure 7 , Figure 8 , Fig.10 and especially Fig.11 The key switch 12 with a key element 13 in the form of a tappet 13a is shown and described. The key switch 12 is assigned to a circuit board 14 and is placed in a carrier 24. The key switch 12 is placed in the drawer 6 with the carrier 24 and the tool rack 7 is placed on top. The components are arranged so that the key switch 12 with the key element 13 protrudes into the receptacle 8, 8a, 8b.

[0128] This situation can be schematically illustrated again by Fig.17 There is a key switch 12 including a key element 13 in the form of a lever 13b. Fig.17 In the illustration, it can be seen in the image plane on the left. Fig.17 The right image plane of FIG. 8 shows a tool 9 inserted into the receiving portion 8 b. The key element 13 and the key switch 12 arranged there are activated by the tool 9. Fig.17As can be seen in the right half of the image, a key element 13 in the form of a lever 13b, which protrudes laterally into the receiving portion 8b, is pressed in there. As a result, the key element 13 of the key switch 12 is actuated and the detector 11 is active. A signal is generated and processed accordingly. The system recognizes that the socket is occupied and that a tool 9 is present. During removal, the key element 13, 13b moves back again at the key switch 12 and the signal becomes negative accordingly, which means that the tool 9 is missing.

[0129] The data processing unit of the tool identification and management system of the workshop trolley 1 receives the signal from the detector 11 and detects the presence or absence of the tool 9 in the receiving part 8 or 8a, 8b. Tool usage data as well as tool status data and / or tool user data can also be detected by means of the data processing unit. The tool inventory as well as information about the maintenance and characteristics of the tools and the user's information are detected and archived and can be displayed via a display that communicates with the data processing unit wirelessly or by wired connection.

[0130] The workshop trolley 1 is also equipped with a locking system, by means of which the drawer 6 can be locked centrally in the housing 3. A component of the data processing unit is the functional electronics, which controls at least one actuator. The actuator is in particular for actuating a locking strip of the locking system. In addition, the functional electronics can have a wireless communication module, in particular Bluetooth or WLAN.

[0131] On the narrow side of the workshop trolley 1 adjacent to the handle 5, a functional area 19 is provided, protected by the handle 5. An interface 20 for an identification element, for example an RFID sensor, is arranged there, by means of which the locking system of the workshop trolley 1 can be opened and closed. Furthermore, an emergency unlocking device is arranged there, comprising a cylinder lock 21, by means of which the locking system can be unlocked manually and mechanically if necessary.
