Description

Workshop car

The invention relates to a workshop vehicle according to the features of the preamble of claim 1.

Workshop trucks of the type in question are typically used where high value tools and small accessories are required for short periods of time in the immediate vicinity of the assembly and disassembly area. In addition, the automotive industry and the aircraft industry fall into this category.

To date, most of the tools have been placed in a substantially closable workshop car casing and are in a shelf or on a drawer that can move laterally with the casing. They can be taken out by the assembler when needed and put back after use.

However, there are a number of uses in which the assembler needs to perform more frequent tool changes, so that taking the tool in the shop car is associated with a time that is not insignificant. The tool must also be returned to its storage location after use, so that it can be retrieved again without a large search action and the time associated with it.

Therefore, starting from the prior art, the object of the present invention is to realize a workshop vehicle in which not only the tools required for assembly and disassembly but also the return of the tools can be used without problems and obvious. Implemented in a shorter time.

The above object is achieved in accordance with the invention in the features of claim 1.

Advantageous further developments are the subject matter of the dependent claims 2 to 9.

According to this, in the height region of the storage surface of the workshop vehicle, at least one storage panel is provided beside the at least one side wall of the housing, the storage panel being provided with a space for the insertion of the tool.

With the storage plate it is now possible to provide all the tools required in the respective use cases, such as screwdrivers, screw wrenches, pliers, socket wrenches with corresponding sleeves and ratchet wrenches, so that the assembler can view these tools without problems and therefore also Take the tools that are appropriate for your idea. Similarly, he can put the tool back into the prescribed position after use, so that the tool is equally available to him when needed.

Depending on the location, the storage board can be replaceable to accommodate the tools that are currently needed. It is also possible to provide a plurality of storage plates in the height region of the storage surface beside the side walls of the housing when a correspondingly large number of tools are required.

Preferably, the storage plate formed in an elongated rectangular shape can be made of metal or plastic, and the configuration of the respective gaps in the storage plate is purposefully adapted to the corresponding tool.

In order to facilitate the assembly of the tool for the assembly and the targeted use of the tools to be stored on the storage plate, the storage plate can be arranged at an angle to the storage surface. This is especially friendly to the fitter and is therefore particularly advantageous from the standpoint of humanity in the face-to-face. If the workshop vehicle is, for example, a workshop vehicle having a drawer that is movable in the direction of the front side adjacent to the fitter, the storage panel can be placed, in particular, on the side of a side wall beside the drawer. The storage plate is then parallel to the drawer or the storage surface with its narrow side. The narrow side of the storage plate adjacent to the drawer's pull-out direction is set lower than the narrow side facing away from the drawer pull-out direction. If the storage plate is located on the rear wall of the housing that faces away from the drawer, then one long side of the storage plate is disposed approximately at the level of the storage surface and the other long side is disposed at a slightly higher level. The assembler therefore always sees all the tools on the storage board and is able to always grab the tools he currently needs without time lag. The storage tool is also no problem.

In particular, when the tool is not to be used, it is expedient for the storage plate to at least indirectly form an integral part of the box-shaped container, which comprises a box-shaped lower part and a cover-shaped upper part. The storage plate can then be arranged in particular in the lower part of the container. Suitably, it is removably loaded into the lower portion. Therefore the tool can be protected and kept, which may not be related to the workshop car. In this connection, the container can be made of metal in the lower part and, in particular, transparent plastic in the upper part. Other material combinations are also contemplated. In the case of the upper part of the transparent hood, the assembler can also accurately see the tools he needs in his work when the container is closed.

It is conceivable that the storage plate is embedded in a frame which can be fixed to the housing without a container. In this way, the storage plate can be loaded into the frame together with the corresponding suitable tool so that the tool can be easily reached. If the storage panel forms part of the container, the entire container can be loaded into the frame.

The frame can be made of plastic or metal. It is preferably fixed to the housing in a detachable manner by means of an elbow part. The elbow part can be integrally connected to the frame.

In order for the container to be more easily removed from the frame and reloaded into the frame, the upper portion of the container is provided with a carrying handle.

In order to ensure the safety of the tool in the container, it is also of interest that the upper part of the container can be locked with the lower part and/or the container as a whole can be locked with the housing. In this way, only the owner of the key can open the container and thus the tool, especially if the tool is of very high value. The locking can be set on one of the long sides of the container or on one of its narrow sides.

Based on the inclined position of the container for the assembly worker, it is furthermore expedient for the container to be inclined on its higher end side in the direction of the lower side of the container. In this way, any part of the container does not extend beyond the rear wall of the assembly in the position of use of the vehicle in the workshop and therefore does not constitute an obstacle.

A further supplementary measure of the container is that in particular a drawer which is accessible from the lower end side of the container is integrated in the lower part. In this drawer, for example, smaller tool parts, for example sleeves, in particular socket wrenches or ratchet wrenches, can be stored. They prevent unauthorized access in the drawer. The drawer can additionally be constructed to be lockable.

Finally, it is particularly advantageous in this connection of the invention that the housing has drawers which are arranged one above the other and which are movable relative to the housing on one side wall. In this case, the storage plate and/or the container with the storage plate are arranged on one lateral side of the housing, in which case, for example, on the other lateral side of the housing, a height is provided at the height of the storage surface for pushing Handle for the workshop car.

The shop truck of the present invention is generally user friendly and improves the handling of the provided tools and the comfort of the fitter.

The container of the present invention is also referred to below as a tool case for receiving an elongated hand tool, in particular for a storage kit, the kit comprising a socket wrench element, a screwdriver and a screw wrench having a base body and The top cover is characterized in that the hand tool is arranged in a vertical orientation in the basic body, and in order to receive the hand tool in a positionally fixed manner, an insert plate is provided on the base body, which substantially completely covers the base opening.

By arranging the insert plate on the insertion opening of the substantially pot-shaped base body according to the invention, the tool can be arranged clearly and compactly, while allowing quick and reliable accessibility for the assembler used. The arrangement of the invention simultaneously ensures that the outer dimensions of the toolbox remain the same or can be reduced relative to the toolbox known from the prior art, while the capacity, ie the number of tools accepted, is increased.

According to the invention, it is thus possible for a large number of hand tools in the form of a wide variety of tools to be placed in a tool case, but which are not designed in their outer dimensions relative to toolboxes known from the prior art. . In contrast, the toolbox is designed to be smaller than the known toolbox even in its outer dimensions within the scope of the invention. However, the capacity for placing hand tools is also increased. Thus more than 50, in particular more than 80, and particularly preferably more than 100 tool varieties can be clearly placed in the toolbox of the invention and each component can be taken quickly. Another particular advantage of the kit of the present invention is that it allows the tool variety located inside the toolbox to be always taken directly from above when parked on a work or work surface.

For this purpose, the hand tool can be removed from the tool box in particular, which makes it possible to carry out a humane and quick removal or insertion possibility in terms of work.

In particular, the insert plate consists of a hard material, preferably of plastic, in particular of a metal material and particularly preferably of light metal and more preferably of aluminum. Here, it is provided that the openings for the receiving tool are indicated, for example by engraving or labeling such as a laser label. Hard materials in particular allow for high firmness because the insertion of a tool with a sharp tool head can cause wear during times that may be used throughout the year. Light metals are particularly suitable because light metals have a high resistance to impact and have very low self-weight.

In a further preferred embodiment, the insert plate has insertion openings which are each adapted in their cross-sectional configuration to the cross-section of the tool to be inserted. In this case, for example, for a cross-shaped screwdriver, there can be an insertion opening of a substantially circular configuration. Conversely, in order to accommodate the nut wrench, an insertion opening of a substantially rectangular configuration is required, which allows insertion of the tool head and is significantly larger than the tool shaft portion at the tool insertion position.

In order to support the positioning, non-loose and non-sloshing of the tool in the insertion opening, it is particularly preferred to position the hand tool in which the locking element is provided for insertion in the insertion opening. This preferably involves a spring leg. But it can also be a rubber seat or a rubber lip. In this case, in particular, a positive-locking and/or friction-locking connection is ensured. The support of the hand tool in the insertion opening is thus realized in a fixed position and provides a valuable touch to the respective user. However, the tool extending from the insertion plate in the inserted state is all precisely positioned according to the invention, so that a normal visible placement of all tools is always obtained after many years of use. Therefore, the appearance of the high-quality display of the tool image is realized.

Further preferably, the insert plate is chamfered on its side. In this case, the edges are adjusted, at least on both sides, preferably also on three sides or even on all four sides. The insert plate can thus be coupled to the basin-shaped base body in a particularly good manner. Each chamfer can be attached to or overlap the side wall of the substrate. Further preferably, the insert plate is coupled to the base body by a bayonet connection and/or a threaded connection. It is thus ensured that the precise and normal placement of the insert in the basic body is always ensured after frequent use for many years. As long as the removal of the insertion plate is required, for example because the object falls into the basic body, this can be performed very simply and quickly.

In particular, the insert consists of a foam material. A variety of different plastics can be used for this purpose, which form a honeycomb structure and a low density. In particular, closed-cell honeycomb foams can be used, in which the walls between the individual honeycomb chambers are completely closed; or open-cell honeycomb foams can be used, wherein the honeycomb chamber walls are not closed. Also contemplated are hybrid honeycomb foams comprising the above two types of honeycomb chambers. Whole skin foams are also conceivable, having a closed, thick skin and a honeycomb core compared to it. In this case, the foam material can in particular have different densities and/or at least partially different hardnesses.

However, the insert may also be made of polystyrene material or Styrodur material (extruded rigid polystyrene foam sheet) within the scope of the invention. In this case, the tool can be fixed in a position-locked manner and, if necessary, can be fixed in a friction-locking manner. Therefore, the fall of the tool is impossible.

It is further preferred that the insert completely fills the substrate. In the context of the invention, the base body is embodied in the form of a basin, which essentially fills the basin substantially completely. In this case, the base body is attached to all sides of the basin and to the bottom of the basin, so that a form-locking integration is obtained.

In order to accommodate each hand tool itself, a receiving opening is formed in the insert, each receiving opening preferably being embodied in a cross-sectional manner for each hand tool. It is within the scope of the invention herein that the cross-sectional area of the receiving opening substantially corresponds to the cross-sectional area of the hand tool that needs to be inserted into the receiving opening. Depending on the application and depending on the tool, the cross-sectional area of the receiving opening can be configured to be slightly smaller than the cross-sectional area of the respective hand tool, so that the hand tool is frictionally locked in a fixed position. If necessary, the receiving opening can also be configured in its cross-sectional area to be slightly larger than the cross-sectional area of the corresponding hand tool, so that removal or easy insertion of the container is possible.

Within the scope of the invention, the receiving opening is between 1 and 40%, preferably between 5 and 30%, in particular approximately 10%, of the outer dimensions of the hand tool to be inserted, in particular the outer dimensions of the tool shaft. An optimized compromise is therefore found between a good positional fastening and a force-locking and form-locking fastening as well as a simple insertion and extraction process.

In a further preferred embodiment, the receiving opening has at least one unloading opening on the edge side. In the case of an insert made of foam or polystyrene, it is thus ensured that the cross-sectional area of the receiving opening does not pass through the formation of cracks or even in the case of many years of use and many times up to several thousand insertion and extraction processes. The analog was damaged. Therefore, surface stress occurring on the inner surface of the accommodation opening can be removed by unloading the slit. Therefore, the receiving opening can also be formed in a star shape or a cross groove shape.

In a further preferred embodiment of the invention, a purifying lip is provided in the receiving opening itself. The tool can thus be cleaned during insertion and removal by purging the lip or by receiving the opening itself or by accommodating the inside of the opening. For example, the oil or grease can be scraped from the tool and, if necessary, absorbed by the configuration of the opening of the insert, so that the tool is at least substantially purified.

In a further preferred embodiment, the inserts are constructed in multiple layers, the division of the layers being perpendicular to the vertical arrangement of the tool. Therefore, it is possible to manufacture inserts particularly inexpensively. Different layers can be manufactured separately. Thus each layer can be specifically adapted to the required conditions. For example, it is thus possible that the layer situated further above is made harder in terms of its material construction than the layer situated further below. It is thus ensured that the position is fixed in the upper region, whereas the force for insertion is kept lower by the softer lower layer. Further layers having a height below 2 cm, in particular below 3 cm, preferably less than 10 cm, are formed more inexpensively than layers such as 15 or 20 cm or even higher.

It is therefore also within the scope of the invention to combine a layer made of a polystyrene material with an additional layer made of a plastic foam material. Within the scope of the invention, the individual layers can, for example, be bonded to one another. However, it is also conceivable for the individual layers to be joined to one another by means of a form-locking joint. In this case, the form-locking engagement can be formed between the layers themselves, by means of a modular principle or by means of a through-pin.

Further preferably, a rubber material or a resin material can also be used. PU foams and/or PE foams are used in particular in the foams used. This relates to polyethylene foam or polyurethane foam.

In a further advantageous embodiment of the invention, the receiving opening for receiving the respective hand tool in the insert is associated with the insertion depth of the hand tool. The receiving opening is formed in particular layer by layer. Within the scope of the invention, it is thus possible for the receiving opening, for example in the uppermost layer, to be formed completely through the layer for each hand tool that needs to be inserted. For example, it can be manufactured by a piercing process or a punching process.

Further, it is preferred within the scope of the invention that the upper opening of the upper layer is provided with a smaller receiving diameter than the opening of the lower layer. Therefore, the guiding and clamping action of the sway of the tool for resisting storage is simultaneously ensured in the upper layer region. In this case, the lower layer essentially assumes a guiding effect, so that it is ensured that the hand tool can be easily inserted and removed in the receiving opening, and nevertheless a reliable fixed position of the hand tool in the receiving opening is ensured. In the case of foams, the density is between 5 and 80 kg/m ³ , in particular between 10 and 70 kg/m ³ , preferably between 15 and 40 kg/m ³ , more preferably between 20 and 30 kg/ Between m ³ . Within the scope of the invention, the upper layer preferably has a density of between 20 and 40 kg/m ³ , in particular between 25 and 35 kg/m ³ , preferably between 28 and 32 kg/m ³ . In connection with this, the density of the lower intermediate layer and the lower layer is chosen between 10 and 50 kg/m ³ , in particular between 15 and 25 kg/m ³ , particularly preferably between 18 and 23 kg/m ³ . It is thus also ensured that an increased clamping effect is achieved by the increased density in the upper layer, and the pivot point which is associated with this on the lower layer is situated in the simple guide of the inserted hand tool.

Within the scope of the invention, the inner diameter of the receiving opening of the upper layer is preferably formed as an interference fit. In particular, the diameter of the receiving opening is reduced by between 1 and 40%, in particular between 5 and 30%, preferably between 10 and 20%, relative to the outer contour of the hand tool 1 to be inserted. Preferably, the intermediate layer and the lower layer form a transition fit, wherein the diameter of the receiving opening is reduced by between 1 and 30%, in particular between 2 and 20% and particularly preferably by about 10%, relative to the outer dimension of the hand tool to be inserted. .

Depending on the insertion depth of the tool, each layer can be adapted to the insertion depth of the hand tool by the punching of the receiving opening, for example, the socket wrench set has only a maximum of 2~3. A small insertion depth of cm, compared to a screwdriver or nut wrench with an insertion depth of up to 10 cm or more.

Therefore, it is possible to accommodate a tool having a limited insertion depth due to its own structure within the scope of the present invention. For example, a screwdriver, due to its tool shaft portion and a handle coupled to the tool shaft portion, collides with the uppermost layer in the region of the handle so that no further insertion is possible. In contrast, the socket wrench set itself is formed as a cylindrical body and correspondingly falls into a recessed receiving opening. In this case, it is necessary for the socket wrench assembly to be inserted too deeply from below by means of the positively locking carrier. In this case, the insertion depth can be adjusted specifically for each tool by a corresponding stratification, wherein a corresponding receiving opening is not sufficient in the deeper layer.

Within the scope of the invention, in particular, the resulting insertion opening or the bottom of the insertion gap can in turn be formed with an additional bottom insert which resists damage to the polystyrene or foam material. For example, the bottom insert can be made of metal or plastic, at least made of a material that is relatively hard associated with the insert.

In particular, the lower layer which is in contact with the bottom of the substrate has a corrugated structure, preferably a granular structure, in particular a surface structure of an acoustic foam. The structure here is adapted to the curve of the eggshell paper as required. It is thus possible for the entire insert to be fixed in position in the basic body, so that a bottom damping is obtained with the insertion of the tool. If the assembler should insert a screwdriver or the like into the tool case of the present invention, the insertion pulse will be buffered by the waveform structure. The manipulation of the toolbox of the invention with the insert in a particularly humanized manner can therefore be determined in everyday use. Again, the insertion noise is attenuated, which in turn reduces the acoustic workload.

Other advantages, features, characteristics and aspects of the invention are part of the description which follows. Preferred embodiments are described in the schematic. They are used to simplify the understanding of the invention.

The above features may be combined with each other arbitrarily, with the advantages brought about by these features, without departing from the scope of the invention.

In Fig. 1, the vehicle 1 is indicated by the reference numeral 1, for example, it is often used in a car factory or an aircraft factory.

The workshop vehicle 1 has a housing 3 supported on the wheel 2 with a storage surface 4 on the upper side. On the side wall 5 of the housing 3, at the level of the storage surface 4, there is a handle 7 for pushing the shop vehicle 1 next to the recess 6 for receiving small materials such as bolts, nuts and washers.

On the front side 8 of the housing 3 there are provided shelves arranged in an overlapping manner for receiving a plurality of drawers 9. These drawers 9 can be removed from the housing 3 via the front side 8. In the illustrated inner position of the drawer 9, they can be collectively locked with a lock 10 so that the drawer 9 cannot be opened unauthorised.

A box-shaped container 12 is arranged on the side wall 11 of the housing 3 opposite the handle 7 substantially at the level of the storage surface 4. The container 12 is suspended from the housing 3 by means of an elbow rail 13 . The elbow rail 13 can be fixed via pins and bolts above the vertical struts 14 provided in the corners of the housing 3.

As can be seen when viewing Figures 1 and 2 together, the container 12 can also be formed by a box-shaped lower portion 15 and a cap-shaped upper portion 16. The lower part 15 and the upper part 16 can be engaged in a form-locking manner and can be locked by means of a lock 17 which is arranged on the longitudinal side of the container 12 or on the end side as shown in FIG. 2 .

A reversible carrying handle 19 is provided on the upper side 18 of the upper portion 16 for moving only the upper portion 16 or for moving the entire container 12 when the container 12 is closed.

As further seen in Figures 1 and 2, the container 12 is disposed at an angle relative to the storage surface 4. In order to prevent some areas on the higher end of the container 12 from exceeding the rear wall 20 of the housing 3, the container 12 is inclined on its higher end side 21 in the direction of its bottom side 22.

As can be seen in particular from FIG. 3, the container 12 can be inserted into the frame 23 and fixed to the housing 3 via a frame 23, which is for example integrally connected to the aforementioned elbow guide 13.

The container 12 can be made of metal or plastic. Thus, as seen in Figure 4, for example, the upper portion 16 of the container 12 can be made of a clear plastic.

In the container 12, substantially in the separation plane of the lower portion 15 and the upper portion 16, there is a rectangular storage plate 24 made of metal or plastic. The storage panel 24 has various storage portions 25 for receiving the tools 26, which are visible, for example, in Figures 1 and 4. These tools 26 may in particular be screwdrivers, screw wrenches, pliers, socket wrenches, ratchet wrenches and sleeves in various different embodiments.

Since the container 12 is arranged obliquely towards the front side 8 with the drawer 9, when the upper part 16 is removed (Fig. 1), the tool 26 can be taken by the fitter in a user-friendly support so that he can grip quickly and reliably The corresponding required tool 26 is taken out of the storage tray 24 and returned to the set position after use.

Depending on the location conditions, it is possible that the storage tray 24 with the various different tools 26 depicted in Figure 5 can be separately incorporated into the frame 23, which is visible from Figure 3. In this case the container 12 can be eliminated.

It can also be seen from Figure 4 that a drawer 28 accessible from the lower end side 27 of the container is integrated in the lower portion 15 of the container 12. The drawer 28 is movable on the guide rail 29. Thus, a flap 30 is provided on the end side 27 which can be locked. The drawer 28 can be used to house small parts such as sleeves.
