Description

The invention relates to a dispensing device according to the preamble of claim 1. Such a dispensing device is of the document US 3 904 034 A known.

Tool boxes and cases, socket wrench sets, bit assortments or cases, ratchet sets, screwdriver sets, etc., in which the respective held tools (sockets [nut]), bits, drills are widely used. .) Turned away with the drive side of the user or lying at least not facing him lying down. In order to use or remove the tools, you have to remove them with one hand at a time, turn them around, hold the drill / cordless screwdriver / air ratchet (hereafter "the machine") with one hand and replace the tool with the other - and vice versa , On the one hand you need two hands, so for example, you have to put down a workpiece or take on a ladder only secure footing with both feet, on the other hand takes the tool change itself unnecessarily long (see, for example DE 103 59 266 A1 ).

Especially nut trimmings can generally not be used in a vertical or overhead position.

To avoid this disadvantage, some magazines have been developed that can be mounted on the machine and allow a quick tool change. However, these are usually expensive to manufacture, increase the machine not insignificant and noticeably worsen the ergonomics of the same, as the machine center of gravity is shifted forward. Due to their system, they also allow only a small selection of tools or machines (see for example GB 23 20 921 A ).

A system that does not have many of these disadvantages is under US 2004/0222115 A1 been published. This consists of a shaft for receiving a nut or a bit, wherein the shaft provided with a stop member and the nut or the bit is formed on a first trajectory inserted into the slot. Farther However, this system is limited in the amount of tools that are available for removal at the same time, as they must be on or executed in two orthogonal paths. It is therefore very well suited for attachment to the belt while using only a few different tools, which it should also serve as a priority. To offer a standard set of tools, but would require a very large user interface and also considerable handling space, as the tools must be taken verschwungvoll right angles to the user interface. The user is still forced to perform movements that are exactly transverse to those that bring the tools in the magazine and back out by the shortest route. As stated in that application under paragraph [0064], the function of that system also requires a version of the constant diameter bit.

That system is in principle designed so that a tool inserted in it can not be pulled out again in the same way that it came in, since it has to push away a spring-loaded locking mechanism when entering the system, which immediately after passing back in his previous position returns. As stated in paragraph [0084], since the system is laterally open (and must be), a second elastic member is needed only to prevent the tool from falling out laterally. It is also not intended for use on, for example, a flat footprint and is suitable unless it is fixed on the same.

Who works with a handle, a gun, a lyre or a machine that allows the inclusion of various tools that are to be rotated, it should be able to change without loss of time or with the help of a second hand. This also applies to the change from bit to square system.

Also, the work space required for one-handed work and the space required for the provision of tools should be minimized so that it corresponds to conventional two-hand magazines. Their bondage to a level surface or a place on the workbench or the tool trolley should be repealed, in order to have the tools in a large selection or the individual and respective needs in the most ergonomically favorable position available, without having to claim work space for it - for example, by the tools on vertical surfaces or components or in front of the work surface are kept. They should be able to stand in the right place for every situation, even when working overhead. This also applies to adapters, extensions, etc., as well as the machine used, which can be parked on any tool, since this is kept in the working direction, without the machine requires extra space on the work surface or a special holder.

The system will also work with both magnetic and quick-release bitholders.

In order to be able to work consistently fast and safely, the change from bit to square drive should also be possible with one hand. The nut should not only be held resilient, but really positive and thus can be securely fixed to the drive.

The above objects are achieved by the features listed in the characterizing part of claim 1.

Further embodiments of the invention relate to the practical and didactically sensible sales presentation of the tools and their design.

In the following, the invention will be explained with reference to some examples:
All embodiments of the dispenser according to the invention initially consist in a known manner from a shaft 20b for receiving a nut 4a and a bit 4b, wherein the shaft 20b provided with a stop member 9 and the nut 4a and the bit 4b on a first movement path 3b in the Shaft 20b is formed insertable.

Essential for the dispenser according to the invention is now, for all embodiments, that the nut 4a and the bit 4b on the first path 3b (first direction of movement) out of the shaft 20b and on a second, the first optional parallel or acute-angled path 3a (second direction of movement) with the stop member 9 is formed positively latched.

FIG. 1a Figure 1 shows the dispenser 1 from the side in a simple embodiment designed to receive bits 4b. The bit 4b is inserted on the lower trajectory 3b with its front end in the dispenser 1.

The bit 4b then only needs to be moved upwards at the rear end in order to come into engagement with the stop member 9 at the circumferential recess 25a. Thus, if the user slightly swings the machine in which the bit 4b is inserted so that the bit 4b reaches the trajectory 3a, and then pulls it backward, the bit 4b remains stuck in the dispenser 1 (assuming it is in a machine or holder 30 that holds it only by friction or magnetically). The path 3a is thus virtually a virtual one for the bit 4b, since the bit 4b or the nut 4a can barely move on it.

In the shaft 20b guide parts 2 for the nut 4a and 4b for the bit are provided. One of the guide parts 2 is formed as a resiliently shaped and resilient detent aid 12 and the other as the stop member 9. After the holder 30 has been withdrawn, the lower guide part 2, which here has the function of the detent aid 12, holds the bit 4b by suitably yielding and resilient connections 13 to the housing 14 in positive engagement with the upper guide part 2, which acts as a stop member 9 here.

Between the (upper and lower) guide parts 2 is or is an end stop 10a is arranged, which has predetermined breaking points in order to adjust it to different bit lengths.

FIG. 1b shows the dispenser 1 simplified in section from above in the same embodiment, without bit 4b. The dispenser device or its body could, for example, be produced as a section of an extruded profile or as an injection-molded part, each with a stamped intermediate wall 17a on both sides. As many bodies and intermediate walls 17a can be attached to these and connected via rods with spring washers etc. by means of the connecting parts 22 with each other and with receptacles 20a in tool cases, trolleys, bags, etc. (see also FIG FIGS. 3b and c ), ie optionally the extruded profile or the injection molded part is preferably formed divided into a plurality of bodies.

Also FIG. 2a shows a dispenser 1 simplified from the side in an embodiment designed to receive bits 4b. At the top of the bit 4b is an end stop 10a in the form of a grub screw with a continuous hexagon socket. It is to be set from front or back to different bit lengths. The end stop 10a is thus provided for setting to different nut or bit lengths optionally with predetermined breaking points (see above) or with an adjusting screw. The bits 4b are fixed positively in all directions in the vicinity of their front end in a plane 5b - only in the direction of the locking aid 12, they can be moved by overcoming the spring pressure. It holds the bit 4b by suitably yielding and resilient connections 13 to the housing 14 in positive engagement with the stop member 9 (see also FIGS. 2b and c ). The insertion aid 8 provided on the shaft 20b has a mark 29a which lies under a protective plate 29b, the protective disc 29b being part of the dispenser 1, which is formed entirely of transparent material.

FIGS. 2b and c show a stop member 9, for example, steel, which can be used in a dispenser 1, which otherwise consists entirely of extruded plastic, to increase the life. In addition, the bit 4b half embracing edge of the stop member 9 supports the use of bits 4b with dispenser side particularly flat circumferential recesses 25a on the shaft (= multi-tooth shaft 24), which lie directly against each other (see FIG. 2f ).

Figure 2d shows the mechanics of a simple but robust dispenser 1, the function arises here only by bending a steel strip.

FIG. 2e shows the cross section of two different dispensers 1, the connecting parts 22 are in the upper than round rails in tenon and groove shape, executed in the lower dovetail rail shape.

FIG. 2f shows a bit 4b with multi-toothed shank 24 with dispenser side particularly flat, circumferential recesses 25a in the manner of barbs. For example, bits 4b of this kind can always be inserted just as deeply, despite their different tips, so that they touch the end stop 10a and therefore are live and do not wobble. A conification 26b in the direction of the lining accelerates the insertion into the same.

FIG. 3a shows a dispenser 1, which is designed for the reception of nuts 4a, from the side. The stop member 9 is here below the tracks 3a and 3b. The nut 4a is inserted on the upper track 3a stuck on the square. The machine on which the square is located is then swung down and pulled backwards. The nut 4a, following until the stop member 9, is then retained by this and slips when the square is out, by gravity back to its rest position 5a. The dispenser 1 has for attachment to the receptacles 20 a dovetail-shaped connecting parts 22 on the back. Several dispensers 1, which are fastened together on the receptacles 20a, together with these form a magazine 16b, which can be suspended, for example, on a perforated metal sheet wall.

One way in which multiple dispensers 1 can be ranked is shown FIGS. 3b and 3c. FIG. 3b shows the variant consisting of parallel partitions 17a, between which the mechanism is mounted, Figure 3c Partitions 17b with molded-on mechanism.

3d figure shows several dispensers 1 for nuts 4a on receptacles 20a, which are arranged in cascade, and the dovetail shape as well as the connecting parts 22, inserted from the side, for example, to allow optimal access to a perforated metal wall.

FIG. 4a Figure 4 shows how dispensers 1 for bits 4b can be mounted on a wall with barb-shaped receivers 20a parallel thereto. The wall could also be, for example, the opened lid of a toolbox, since the bits 4b are retained on the same by spring pressure against the stop member 9, even if it is closed.

At the same time shows FIG. 4a the movement cycle when inserting a double-sided bit 4b with two equal tips, which is held by an automatic holder 30 - to the Wiederentnehmen. The two same peaks allow the user to always know what bit it is.

1. A) Die Figur zeigt den leeren Dispenser 1. Dem Stoppglied 9 ist eine Feder zugeordnet, um das Bit 4b gegen das Stoppglied 9 zu drücken. Dazu ist die Feder zwischen einer Wandung des Schachts 20b und der Rasthilfe 12 angeordnet, d. h., die Feder drückt die Rasthilfe 12 (bei fehlendem Bit) gegen das Stoppglied 9.
2. B) Das Bit 4b wurde bis zum Endanschlag 10a eingesteckt, die vordere Fläche des Halters 30 berührt gerade die Fläche 11a des Bitfutterabweisers 11.
3. C) Durch Hochkippen der Maschine / des Schraubers 33 annähernd um einen Punkt auf der Ebene 5b wird der Kragen 30a des Halters 30 nach hinten gedrückt, da das Bit 4b von der Rasthilfe 12 mit der dispensereitigen umlaufenden Vertiefung 25a gegen das Stoppglied 9 gedrückt wird und so nicht nach hinten ausweichen kann. Dadurch wird das Bit 4b vom Halter 30 freigegeben.
4. D) Der Halter 30 kann also abgezogen werden,
5. E) das Bit 4b schnappt dann in seine Ruhelage 5a.
6. F) Bei dem erneuten Aufstecken des Halters 30 wird der Kragen 30a desselben wieder nach hinten geschoben (was bei manchen Bithaltern nötig ist, um überhaupt Bits in dieselben einzuführen).
7. G) Wird dann die Maschine wiederum gekippt, so wird das Bit 4b automatisch durch die bitseitige Fläche 10c des Endanschlages 10a nach hinten gedrückt, bis es in Eingriff kommt mit dem Stoppglied 9,
8. H) der Kragen 30a des Halters 30 kann wieder nach vorne federn (falls er nicht automatisch verriegelt hat, tut er es jetzt). Durch leichten Druck des Bits 4b nach unten wird die Feder der Rasthilfe 12 zusammengedrückt und das Bit 4b kann wieder herausgezogen werden.

In detail:

1. A) The figure shows the empty dispenser 1. The stop member 9 is associated with a spring to press the bit 4b against the stop member 9. For this purpose, the spring is arranged between a wall of the shaft 20b and the detent aid 12, ie, the spring presses the detent aid 12 (in the absence of a bit) against the stop member 9.
2. B) The bit 4b has been inserted to the end stop 10a, the front surface of the holder 30 just touches the surface 11a of the Bitfutterabweisers 11th
3. C) By tilting the machine / the screwdriver 33 approximately at one point on the plane 5b, the collar 30a of the holder 30 is pushed backwards, since the bit 4b of the snapping aid 12 circulates with the dispensers Recess 25a is pressed against the stop member 9 and so can not escape to the rear. As a result, the bit 4b is released from the holder 30.
4. D) The holder 30 can therefore be removed,
5. E) the bit 4b then snaps into its rest position 5a.
6. F) When re-attaching the holder 30, the collar 30a thereof is pushed backwards (which is necessary in some bit holders to insert bits into them at all).
7. G) If the machine is then tilted again, the bit 4b is automatically pushed back by the bit-side surface 10c of the end stop 10a until it engages with the stop member 9,
8. H) the collar 30a of the holder 30 can again spring forward (if he has not locked automatically, he does it now). By pressing lightly the bit 4b down the spring of the locking aid 12 is compressed and the bit 4b can be pulled out again.

After a short settling-in period, these processes take place automatically and unconsciously in such a short time that it is difficult to track them.

FIG. 4b shows comparable dispenser 1, as they could be inserted, for example, in a tool box for use with magnetic holders 30. Shown left is a double-sided bit 4b in rest position 5a. Even without further markings, the user can recognize which bit 4b is involved. The holder 30 is simply pushed to the stop, then moved approximately parallel, approximately at right angles to its axis of rotation or the path of movement 3a and pulled out with bit 4b (center of the figure).

On the right the empty dispenser 1 can be seen.

FIG. 5a shows how a magazine 16b could be constructed in order not to require too much space despite double-sided bits 4b. The magazine lid 31 is deported laterally.

FIG. 5b shows the same magazine 16b open. It could be used with magnetic or with automatic holders 30 if the collar 30a of the holders 30 used is compatible or the ground contact is ensured by sufficient weight of the magazine 16b or other anchors.

FIGS. 6a and b show how Dispenser 1 according to the invention can form the outputs of a sales display for bits 4b. In this case, the shaft 20b is designed to accommodate either a plurality of nuts 4a and / or a plurality of bits 4b. Customers buying bits 4b will inevitably experience and appreciate the function and reliability of the technique of the invention. The release is done only not by movements of a machine with bit holder, but by pressing a spring-loaded trigger 28, which pushes the bit 4b of the stop member 9, ie the stop member 9 is operatively connected to a preferably spring-loaded release 28.

FIG. 6a shows a dispenser 1, in which the bits 4b are pressed by a prestressed spring in the direction of the input area 7, so that upon removal of a bit 4b, the next comes immediately after, until it is caught by the stop member 9.

FIG. 6b shows a display with multiple bit memories 19. The reliability of the system according to the invention is the customer even more clearly. After pulling out a string of bits 4b, each connected by bit connectors 27b, or a single bit 4b, it must tear a bit connector 27b which has a predetermined breaking point 27c therefor and at its ends the sheath 27a, respectively of a 4b bit. Thus, individual bits 4b do not easily disappear between other goods, it is possible to dispense with the spring in the bit memory 19 and the bit connector 27b provided with a theft protection chip or the like.

FIGS. 7a to 7e show a magazine 16b, which is intended for permanent assembly in the workplace with the best possible ergonomics and use of the available space. Optimal workplaces are generally characterized by the avoidance of unnecessary ways or handles, easy cleanability, intuitive usability, a flexible working surface and more and more due to theft security. With more and more tools to hold, the still-available workspace quickly shrinks as it's deployed on it. Pushing tools back and forth to work takes time. In addition, every tool on the work surface leads to more clutter. Tools that have their fixed place speed up the work, because search work is eliminated and because it can be accessed intuitively.

The magazine 16b in Figure 7a is therefore arranged in front of the worktop, the throat between magazine 16b and table edge 32 still offers as a shelf for extensions, etc. The fastening means 23 in the form of screw holders 23a engage under the worktop, where they can be screwed inconspicuously. It makes sense to run them as long slots, so that the magazine 16b can be removed without removing the screws completely. So it is also usable or wegschließbar in other places. Of course it can also be lockable - and, for example, with special screws to prevent theft.

The magazine 16b can be rotated about its longitudinal axis, for example, to be adapted to the particular work situation, different users.

FIGS. 7a and 7c show an adapter 4d (bit hexagon to square) with molded conical character carrier 29c. The use of this adapter 4d has the advantage that even the change from bit to square use can be done with one hand and system conform.

FIG. 7b shows in section how the provided with a spring 10d expeller 10b, which is slidably mounted between the guide members 2, a bit 4b clamped with integrally formed sign carrier 29c, also the attachment frontally for example on a beam, which may also be vertical, or one Cabinet wall etc., because often are the sides of the workstations vertical unused mounting options (then would be FIG. 7b So a plan view).

In this concept, the spring expeller 10b virtually replaces the detent aid 12 because it holds the nut / bit 4a / b firmly on the stop member 9 via the sign support 29c. To come out, nut 4a or bit 4b must compress the expelling spring 10d in any case and overcome friction. Only strong vibrations could cause this unintentionally.

FIG. 7c shows in section that the individual dispensers 1 have guide parts 2, between which a resilient expeller 10b can slide. If the dispensers 1 are to be used only in a horizontal position, no resilient expeller 10b is necessary, but pleasant.

FIG. 7d shows in section how the magazine 16b can be moved down to allow also the handling of objects that protrude for a short time (for example, when turning around) over the table edge 32. The resilient expeller 10b clamps here a nut 4a against the stop member 9, therein is a conventional adapter 4d bit hex on square.

Figure 7e shows the attachment to a shelf or a shelf side wall (then = top view) for the most part without lid 31. By loosening the internal nuts magazine 16 b can be moved up / down / rotated. The user can not use automatic chucks in this embodiment, only magnetic or friction chucks. Automatic chucks could be combined with the technique of FIG. 10a and 10b be used.

FIGS. 8a to 8e show a ratchet box similar to the usual boxes of blown thermoplastic in section. It can be easily fixed to tabletops by means of a sheet storable in the box so that its contents can be ergonomically used according to the invention.

Boxes lying flat on the table require more floor space than set up, tools can indeed be easily removed / inserted with bare hands, but with a machine in hand without the use of a second hand, it is especially for the use according to the invention particularly advantageous if the user interface has approximately 45 degrees inclination to the table surface.

The ratchet box is engaged by means of the sheet which is bent up at the front and in two recesses 16c of the tool carrier 16a (here ratchet box), about a threaded hole approximately in the middle and two screw holders 23a at the two outer ends in the form of screws with hardened tips attached to the table top. The cut is therefore only at the central screw through the middle, otherwise through the right or left outer ends of the sheet. This clamps the removed cover of the ratchet box now so below the same, that still creates a shelf for screws, etc. To fix this ratchet box on a table top, only the central screw must be tightened. Both adapter 4d bit hexagonal square and square nut extension 4c and lyre have a dispenser-side circumferential thickening 25b barbs. The function corresponds to the off FIG. 3a known.

FIG. 8b shows the closed ratchet box with inserted sheet metal.

FIG. 8c shows the use of another clamping plate. It has the task of restricting the already very scarce storage space on a tool cart not even more by the filing of the ratchet box and the machine used and at the same time offer a practical parking position for the same.

It is located at the rear approximately flat on the tool trolley surface, was bent behind the edge of the same upwards and in front again U-shaped pulled down to below the level of the rear flat. It engages in recesses 16c of the tool carrier 16a and has a threaded hole approximately in the middle of the rounding of the "U" and Klemmschraubgewindelöcher on the front sloping surface. With the clamping screws, the tool carrier 16a can be attached to almost any tool trolley without wobbling.

FIG. 8d shows the application of FIG. 8c on the tool cart in the overall view. FIG. 8e shows the same sheet when using the ratchet box at a table edge 32nd

FIG. 8f shows a tool cart concept that allows optimal working, because it is already integrated in its position in space flexible tool carrier 16a. Tool holders whose position in space is held by friction or gas springs are known, for example, by dental practices. For the application according to the invention, however, arresting in the required position is absolutely necessary since the operating forces would otherwise change the position or would require a mechanics which are too stiff. It is also very advantageous for the use according to the invention if the machine (s) used can also be parked with tools in the tool carrier 16a at the same time. As a result, however, the weight to be held can change in such a way that no fixed position would be durable without locking. In the handle of the tool carrier 16a therefore a key 16d is integrated, which cancels the position locking of the tool carrier 16a when actuated.

FIG. 9a shows the application of the invention to a plastic tool box. The lid thereof has similar wells 20b, in which the dispenser 1 stuck. The right hand dispensers 1 for bits 4b sit between spacers 17d which balance the smaller width of the bits 4b with respect to those of the nuts 4a and provide sufficient working space around the bits 4b. The left dispensers 1 serve only to receive nuts 4a. In the lower row missing two locking aids 12 and an intermediate wall 17 a. With 20b there is the shaft bottom, which is also the inside of the cover here. Important for the function are still the fastening means 23 in the form itself (by gravity) arresting lid holding hinges 23b, so not coincident by the operating forces of the lid. Right and left in the tool box are dispenser 1 for receiving drills or taps, which are similar in function to those in the lid.

FIG. 9c shows a tool box made of plastic with a closed lid, the folded lid holding hinge 23b is shown in dashed lines.

FIG. 9d shows the opened tool box, the lid holding hinge 23b is opened and locked by gravity, to close the lid, it must first be raised.

FIG. 9e shows a section through the lower portion of the tool box lid. Into the shafts 20b, the spacers 17d and intermediate walls 17a are inserted through notches 20d in the projections 20c on the shafts 20b. The connecting parts 22 engage in recesses in the slots 20b in the end position, ie, optionally the intermediate walls 17a and / or spacers 17d are provided with connecting parts 22 cooperating with recesses or projections provided on the slots 20b. Between the spacers 17d and intermediate walls 17a parts are inserted, which combine the function of the resilient expeller 10b, the locking aid 12 and the protective plate 29b, ie, in the shaft 20b is a function of both the expeller 10b and the locking aid 12th realizing part arranged.

FIG. 9f shows at the same section that both nuts 4a and 4b can be used. The resilient expeller 10b compensates for the difference in length between the nut 4a and the bit 4b, and prevents the nut 4a / bit 4b from tilting. The snapping aid 12 compensates for the difference in thickness and serves as an aiming aid, since it runs obliquely to the nut / bit central axes 6a, also a somewhat inaccurate and therefore too deeply inserted tool is guided into the rest position 5a. The other guide parts 2 act accordingly. Since the locking aid 12 is made of transparent plastic, the inserted below the side of the character carrier 29c is protected with the sign 29a from damage. The holder 30 can be used for both types of tools, it has on one side a bit holder and on the other a square.

FIG. 9g shows a well 20b with environmental cutouts from the user's point of view. From the left can be seen: a shaft section without dispenser 1, right next to a spacer 17d, then an empty dispenser 1 for bits 4b, a spacer 17d, a dispenser 1 with bit 4b, an intermediate wall 17a, an empty dispenser 1 for nuts 4a and three dispensers 1 with nuts 4a and partitions 17a. At the Shaft 20b are cuts 20d for insertion either of intermediate walls 17a and / or spacers 17d provided. Through the notches 20d on the projections 20c on the shaft 20b intermediate walls 17a or spacers 17d can be inserted at the discretion of the user, depending on whether bits 4b or nuts 4a are to be accommodated.

FIG. 9h shows the same shaft 20b perpendicular to it from above. Also at the rear end of the same are projections 20c with cuts 20d, which fix the clipped-in dispenser 1 in the lateral direction by a connecting part 22 at the rear end.

FIG. 9i shows the same shafts 20b as FIG. 9a , and 9e to 9f in a spatial perspective, but above an empty slot 20b, including a series dispenser 1, for bits 4b, including one for nuts 4a, including a spacer 17d and a partition wall 17a.

FIG. 10a shows a (cordless) screwdriver 33 in the suitcase, which also serves as a parking station for the same and as a magazine 16b for the tools, in the closed, stackable state in section. The special feature of this magazine 16b is that the separation of the tools from the screwdriver 33 requires no pulling forces, so that the magazine 16b neither anchored nor must be connected to heavier objects (such as toolbox ...), but that both bits 4b and nuts 4a be connected with the screwdriver 33 automatically true form-fitting and can also be changed between the two with one hand. Required for this is only a table edge 32 or the like, which prevents slipping backwards, as long as the magazine 16b occupies the generally ergonomically favorable - about 45 degrees - position. A magazine 16b similar design, which is to be operated vertically from above or with anti-slip equipment of his soil and at an angle to it, does not need a table edge to work.

From left to right is an empty dispenser 1 for bits 4b, and one shown at bit 4b, then a dispenser 1 used for both bits 4b and 4d adapter bit hex on square and square nut extensions 4c can with an adapter 4d bit hexagon on square, then four dispensers 1 for and with nuts 4a and in the middle one without nut 4a. On it is the screwdriver 33, seen from the front.

FIG. 10b shows the same magazine 16b in working position and the workflow as well as an enlarged detail of position 4. far left. The magazine lid 31 has been folded rearwardly and clipped under two hooks at both rear ends of the magazine 16b (to close it, the hooks are slightly bent outward to release the magazine lid 31). The wrench 33, which has a permanently mounted automatic chuck with holder 30, is pictured, except under 9, only up to and including torque setting ring.

1. 1. Im Halter 30 steckt ein Adapter 4d Bit-Sechskant auf Vierkant und wird in eine im Magazin 16b befindliche Nuss 4a eingeführt. Der Stössel 4e, der normalerweise durch eine schwache Stösselfeder 4f nach außen gedrückt wird, wurde schon zurückgedrückt, weil die Feder 1b stärker ist als die des Stössels 4e - siehe auch Detail von Position 4. Dadurch kann die Kugel 4g in die Aussparung des Stössels 4e rutschen und der Vierkant kann in das Loch der Nuss 4a eingeführt werden.
2. 2. Der Adapter 4d steckt in der Nuss 4a. Durch leichtes Hochkippen des hinteren Endes des Schraubers 33 kommt die in der Figur rechte Kante der Nuss 4a frei und die Nuss 4a kann herausbewegt werden. Sie wird zuerst von der dicken Feder, die hier die Funktion von federndem Austreiber 10b und der Rasthilfe 12 übernimmmt, und der Entsicherungsfeder 1b nach außen gedrückt. Erst, wenn die Entsicherungsfeder 1b ihre volle Länge erreicht hat, kann der Stössel 4e wieder von der Stösselfeder 4f nach außen gedrückt werden und damit die Kugel 4g nach außen drücken. Damit ist dann die Nuss 4a formschlüssig mit dem Schrauber 33 verbunden. Sollte man den Adapter 4d in der Nuss 4a stecken lassen wollen, so könnte dieser jederzeit vom Halter 30 getrennt werden durch Zurückziehen seines Kragens 30a mittels der umlaufenden integrierten Trennhilfe 30b des Halters 30, wie hier gezeigt.
3. 3. Die Nuss 4a wird am Stoppglied 9 vorbei aus dem Magazin 16b gezogen und benutzt.
4. 4. Eine Nuss 4a wird nach Benutzung am Stoppglied 9 vorbei in das Magazin 16b gesteckt - siehe auch Detailvergrößerung Figur 10c.
   Noch ist die Nuss 4a formschlüssig mit dem Schrauber 33 verbunden, denn der Stössel 4e drückt die Kugel 4g noch aus dem Adapter 4d in die Nuss 4a. Der in der Figur gezeigte Winkel der schiefen Ebene der Einbuchtung des Stössels 4e gibt die realen Verhältnisse nur ungefähr wieder, er muss mindestens Selbsthemmung bewirken und kann auch 0 Grad betragen.
   Bei herkömmlichen Adaptern rastet die Nuss zwar auch über eine Kugel ein, diese wird aber nur von einer Feder nach außen gedrückt, es entsteht also nur eine kraftschlüssige Verbindung. Deshalb löst sich zum Beispiel beim Verkanten der Nuss dieselbe oft auch wieder unbeabsichtigt vom Adapter.
   Bei der in Figur 10b beschriebenen Ausführungsform der Erfindung kann die Nuss 4a auch unter sehr ungünstigen Bedingungen nicht von dem Adapter 4d rutschen. Dadurch werden Suchzeiten bzw. Verluste (Nuss in Motorraum bzw. Triebwerk oder von Leiter gefallen und Verletzungen vermieden, es kann oft schneller und immer einhändig gearbeitet werden, weil die Nuss bestimmt nicht an der Schraube bleibt, und die Zufriedenheit mit der Arbeit steigt auch.
   Sowohl der Adapter 4d als auch die Bits 4b weisen oben erhabene Zeichen 29a (Abbildungen der Klinge/des Vierkants) auf.
5. 5. Wenn die Nuss 4a bis auf Anschlag in das Magazin 16b eingeführt worden ist, wird der Schrauber 33 mit seinem hinteren Ende etwas abgekippt, so dass die Nuss 4a mit ihrer Oberkante unter das Stoppglied 9 kommt.
6. 6. Da zu diesem Zeitpunkt (wie unter 2. zu sehen), der Stössel 4e bereits wieder die Kugel 4g freigegeben hat, und die Entsicherungsfeder 1b den Stössel 4e über den Entsicherer 1c auch gedrückt hält, bis der Adapter 4d aus dem Magazin 16b heraus ist, kann dieser nun problemlos ohne Nuss 4a aus dem Magazin 16b gezogen werden. Wie ersichtlich, weist der federnde Austreiber 10b ein mittiges Loch auf, wobei in dem Loch ein Entsicherer 1c mit einer Entsicherungsfeder 1b am Schacht 20b angeordnet ist.
7. 7. Wird der Adapter 4d nun in einen Dispenser 1 eingeführt, der über einen Bitfutterabweiser 11 verfügt (hier ist ein Dispenser 1 mit zwei Stoppgliedern 9 gezeigt, der Adapter 4d oder Bits 4b aufnehmen kann), so wird der Kragen 30a des Halters 30 gegenüber dem Bit 4b durch Druck auf die Maschine / den Schrauber 33 nach hinten gedrückt. Dadurch federt die Nase 30c, mit der das Bit 4b über die futterseitige umlaufende Rille 26a im Halter 30 formschlüssig festgehalten wird, zurück und gibt es frei.
8. 8. Durch leichtes Herabkippen des hinteren Endes des Schraubers 33 kommt das Stoppglied 9 in der dispenserseitigen umlaufenden Vertiefung 25a zu liegen.
9. 9. Das Bit 4b wird von der Rasthilfe 12 an der dispenserseitigen umlaufenden Vertiefung 25a gegen das Stoppglied 9 gedrückt und bleibt so fixiert, auch wenn der Schrauber 33 zurückgezogen wird.
10. 10. Um das Bit 4b mitzunehmen, muss das hintere Ende des Schraubers 33 leicht hochgekippt werden, bevor er zurückgezogen wird (siehe oben). Auf den ersten Millimetern wird das Bit 4b zwar vom Halter 30 noch nicht fixiert, aber da es auf dieser Strecke noch von der Rasthilfe 12 geschoben wird, ist ein lückenloser Übergang von Magazin 16b zu Schrauber 33 gegeben.

From bottom right to top left shows FIG. 10b :

1. 1. In the holder 30 inserted an adapter 4d bit hexagon on square and is inserted into a located in the magazine 16b nut 4a. The plunger 4e, which is normally pushed outwardly by a weak plunger spring 4f, has already been pushed back, because the spring 1b is stronger than that of the plunger 4e - see also detail of position 4. This allows the ball 4g in the recess of the plunger 4e slip and the square can be inserted into the hole of the nut 4a.
2. 2. The adapter 4d is in the nut 4a. By slightly tipping the rear end of the screwdriver 33, the right in the figure, the edge of the nut 4a is released and the nut 4a can be moved out. It is first pushed outward by the thick spring, which here assumes the function of resilient expeller 10b and the detent aid 12, and the armature spring 1b. Only when the Entsicherungsfeder 1b has reached its full length, the plunger 4e can be pressed again by the plunger spring 4f to the outside and thus press the ball 4g to the outside. So then the nut 4a is positively connected to the screwdriver 33. If you want to put the adapter 4d in the nut 4a, so this could be separated at any time from the holder 30 by retracting his collar 30a means the circumferential integrated separation aid 30b of the holder 30, as shown here.
3. 3. The nut 4a is pulled past the stop member 9 from the magazine 16b and used.
4. 4. A nut 4a is inserted after use on the stop member 9 past in the magazine 16b - see also detail magnification FIG. 10c ,
   Still, the nut 4a is positively connected to the screwdriver 33, because the plunger 4e presses the ball 4g still from the adapter 4d in the nut 4a. The angle shown in the figure of the inclined plane of the recess of the plunger 4e is the real conditions only approximately, he must cause at least self-locking and can also be 0 degrees.
   In the case of conventional adapters, the nut also engages over a ball, but this is only pushed outward by a spring, so that only a frictional connection is created. Therefore, for example, when tilting the nut often inadvertently detached from the adapter again.
   At the in FIG. 10b described embodiment of the invention, the nut 4a can not slip from the adapter 4d even under very unfavorable conditions. As a result, search times and losses (nuts in the engine compartment or engine or ladder are avoided and injuries are avoided, it can often be worked faster and always with one hand, because the nut certainly does not stick to the screw, and the satisfaction with the work also increases.
   Both the adapter 4d and the bits 4b have upper raised characters 29a (images of the blade / square).
5. 5. When the nut 4a has been inserted all the way into the magazine 16b, the screwdriver 33 is slightly tilted with its rear end, so that the nut 4a comes with its upper edge under the stop member 9.
6. 6. Since at this time (as can be seen under 2.), the plunger 4e has already released again the ball 4g, and the Entsicherungsfeder 1b keeps the plunger 4e on the Entsicherer 1c also pressed until the adapter 4d from the magazine 16b out is, this can now be easily removed without nut 4a from the magazine 16b. As can be seen, the resilient expeller 10b, a center hole, wherein in the hole a Entsicherer 1c is arranged with a Entsicherungsfeder 1b at the shaft 20b.
7. 7. When the adapter 4d is now inserted in a dispenser 1 having a bit food deflector 11 (here a dispenser 1 with two stop members 9 is shown which can receive adapter 4d or bits 4b), the collar 30a of the holder 30 will face Bit 4b pressed by pressing the machine / screwdriver 33 backwards. As a result, the nose 30c, with which the bit 4b is positively held in the holder 30 via the circumferential groove 26a on the feed side, springs back and releases it.
8. 8. By slightly tilting down the rear end of the screwdriver 33, the stop member 9 comes to lie in the dispenser-side circumferential recess 25a.
9. 9. The bit 4b is pressed by the locking aid 12 on the dispenser-side circumferential recess 25a against the stop member 9 and remains fixed, even if the screwdriver 33 is withdrawn.
10. 10. To take bit 4b, the rear end of the screwdriver 33 must be tilted up slightly before retracting (see above). Although the bit 4b is not yet fixed by the holder 30 in the first millimeter, since it is still being pushed by the detent aid 12 on this path, there is a gapless transition from the magazine 16b to the screwdriver 33.

All coupling and decoupling operations are carried out under pressure on the magazine 16b, pulling forces on the same do not arise in this embodiment. Therefore, when using this embodiment, for example, in the lid of a tool case no gravity-retaining lid holding hinge 23b is necessary.

When connected to a light, but approximately vertically from above to be operated magazine 16b can be dispensed with a fixation of the same against pulling up.

FIGS. 11a to 11g show a magazine 16b, which does not have to be fastened anywhere and without resilient ejector 10b and sprung collar 30a of the holder 30th works if bits 4b or nozzle 4a, dispenser 1 and holder 30 match each other.

The holder 30 has on one side a bit holder, on the other a nut square and in between a hex shaft. The magazine 16b can also be used separately from the tray 35, it is connected to the same by two hook plates, which engage in slots of the tray 35 ,.

FIGS. 11a and 11b The force required to separate the tool and holder 30 is generated by tilting the latter, with bit 4b or nut 4a and holder 30 being levered apart at its collar 30a by the stop member 9. FIG. 11a shows the removal of a nut 4a, FIG. 11b the removal of a bit 4b. The processes are reversible.

FIG. 11c : The stop 21 acts as the front 21, which has corresponding openings. This works both with magnet, such as friction holders or nuts 4a.

FIG. 11d shows the magazine 16b in conjunction with a tray 35th

FIG. 11e and 11f Although the trays usually used in tool cases are suitable for small parts such as screws and dowels that are used on a ladder, a screwdriver can not normally be transported well on it. In turn, the complete tool box is often too bulky at the workplace. The problem of being able to transport everything with one hand and thus to be able to do a work as efficiently and safely as possible is achieved according to the invention by the magazine 16b having a stop member 9 which is not quite as narrow as the stop members 9 for receiving bits 4b , Thus, the holder 30 (clamped in the drill chuck) can be hooked against its hexagonal shaft so that it can not rotate. The screwdriver 33 is thus the handle of the tray 35 - so here is the one-handed operation continuously possible. Ladders can be climbed safely!

FIG. 11f : The screwdriver 30 parks when parking the tray 35 automatically in optimal starting position. The tray 35 has openings 36 in the handle, which are suitable for parking the screwdriver 33, even if the holder 30 is clamped with the thick end to the front or even a nut 4a sits on the square.

FIGS. 12a to 12d show a magazine belt with one empty and one occupied dispenser 1 for nuts 4a and bits 4b.

FIG. 12a : In order to be able to work as quickly as possible, the nuts 4a also have bit shafts so that any type of tool without adapter change can be used with any screwdriver 33 with bit, magnet, or friction chuck.

To prevent bits 4b from jumping out of their dispensers 1 by accidental touches, they are mounted between the same spacers 17d which, for example, keep garments at a distance.

FIG. 12b The stop member 9 encloses the bit 4b like a collar, so that even bits 4b with a conventional groove without a lateral locking aid 12 can be reliably held.

FIG. 12c The bit 4b is pressed downwards (from the holder 30 not shown here) and outwards at the top end.

FIG. 12d : It can be taken obliquely upwards. The process is reversible.

Summarized again, the invention relates to a nut or bit dispenser 1, which pretends by guide parts 2 tracks 3a, 3b for the nuts 4a and 4b bits or their holder 30, a rest position 5a specifies, from the out or in the in each case at least one of the tracks 3a, 3b can be selected, and which has at least one stop member 9 which pulls out the nuts 4a, bits 4b in the direction one of the tracks 3a, 3b can prevent, and put in the nuts 4a and 4b bits with the lining side (the same rear) end to the outside.

This dispenser is characterized in that these webs 3a, 3b both extend approximately in extension 6b of the nut or bit center axis 6a of the rest position 5a of bit or nut 4b, 4a, and run substantially parallel to one another, are at an angle α to each other , wherein this angle α is between 5 and 40 degrees, preferably about 10 to 20 degrees. Here, the path 3a for the bit 4b and the nut 4a on the stop member 9 and the track 3b is directly past the stop member 9, wherein the stop member 9 is fixed or immovable, the track 3b of the bit 4b and Nut 4a, on which the bit 4b and the nut 4a are inserted, is identical to that on which they are brought out again.

The nuts 4a or bits 4b are fixed in a form-fitting manner at or in the vicinity of their dispenser-side (= front) end, at least in one plane 5b, in all directions except for the catch aid 12. The tracks 3a, 3b meet in the rest position 5a. In addition, the tracks 3a, 3b intersect behind the bit tip. There are on all sides of the nuts 4a and 4b bits except the input area 7 facing side at or near its front end guide parts 2. These guide parts 2 are arranged substantially parallel to the tracks 3a / 3b. They have at least one insertion aid 8 at the entrance area 7. This is formed by removing guide parts 2 from each other to the outside. The stop member 9 can engage positively in one or more recesses 25a of the nuts 4a or bits 4b only from one side approximately at right angles to the direction of movement or it is in the rest position 5a before parts thereof or in connection with them.

The stop member 9 has an approximately U-shaped projection into which a dispenser-side circumferential recess 25a of a bit 4b or the shaft of a bit holder fits positively. Furthermore, the stop member 9 and the guide members 2 are formed so that the nuts 4a and 4b bits can fall by gravity into the rest position 5. The stop member 9 and the guide parts 2 are shaped such that the nuts 4a and 4b are released by pivoting about the angle alpha become. The stop member 9 fits tightly between the liner-side circumferential groove 26a of the bit 4b and the collar 30a of the perpendicular holder 30, so that a change in inclination of the same both unfolds. Further, the stopper member 9 fits exactly between the liner-side circumferential groove 26a of the nut 4a and a surface located on the upright holder 30, so that a change in inclination of the same both breaks apart. The guide parts 2 are shaped such that the web 3b optionally deviates downwardly from the web 3a, deviates upward from the web 3a, deviates to the right or left of the web 3a, deviates obliquely to the side from the web 3a, or that the Web 3b, on which the holder 30 with bit 4b, 4a is inserted into the dispenser 1, if they are to remain in the same, is different from the web 3a, which describes the holder 30, if bit 4b, 4a remain in the dispenser 1 and he should be deducted from the same.

In this case, one or more guide parts 2 are designed resiliently. A guide member 2 is an end stop 10a for the insertion movement. This end stop (10a) is optionally interchangeable, adjustable and / or combined with a resilient expeller 10b, which is in an empty position in front of the end stop 10a, and can spring back under load , It is further provided that the resilient expeller 10b has a central hole, that in the hole a Entsicherer 1c with a Entsicherungsfeder 1b is attached to the dispenser 1, that the Entsicherer 1c essentially from a movable inner sleeve 1d with mushroomed dispenserseitigem edge and one on the dispenser 1 fixed outer sleeve 1e is that can slide in it axially and that the outer sleeve 1e has at its upper end an inwardly drawn edge which holds the Entsicherungsfeder 1b via the inner sleeve 1d under tension.

A Bitfutterabweiser 11 is attached or can be attached, the surfaces 11a, 11b, one of which is perpendicular to one of the tracks 3a and 3b. This Bitfutterabweiser 11 further comprises surfaces 11a, 11b, which extend approximately parallel to the bit-side surface 10c of the end stop 10a. These surfaces 11a, 11b surround the tracks 3a, 3b, wherein between the surfaces 11a and 11b a rounded transition 11c is formed. There is also a 12-step help that the nuts 4a and 4b bits press against the stop member 9. In the input area 7 in front of the stop member 9, a guide part 2 is designed to be resilient, which represents an insertion aid 8, wherein the spring force of this guide member 2 is less than that of the locking aid 12th

In the input area 7, a guide part 2, the bit feed deflector 11, a part of the nut 4a, the bit 4b or another part has a mark 29a which indicates the type of tools belonging to this dispenser 1. In this case, the sign 29a is mounted under a protective plate 29b, wherein the part which has the mark 29a, is transparent, and thus itself forms the protective plate 29b, wherein the protective plate 29b or a character carrier 29c can be inserted from the side and wherein the protective disc 29b or a character carrier 29c can be clipped or glued from the rear or front.

In addition, it is envisaged that several dispensers 1 will be connected to or in magazines 16b, i. H. All dispensers 1 for nuts 4a and 4b are freely interchangeable with all other dispensers 1. In this case, the dispensers 1 each consist of parallel intermediate walls 17a with mechanics fastened therebetween, the intermediate walls 17a representing spacers 17d. Alternatively, spacers 17d can also be present between the dispensers 1, the mechanism being formed from a part that is an integral part of the tool carrier 16a (eg the stop member 9) and at least one part that is inserted into the tool carrier 16a can (for example, the resilient expeller 10b and the locking aid 12).

The dispensers 1 can each also consist of an intermediate wall 17b with an integrally formed mechanism, with an end plate 17c also being provided for closing a row of dispensers 1. Furthermore, the mechanism largely consists of a bent steel strip 18, which provides the desired functions essentially by bending in a plane.

It is further provided that the dispenser 1 form sales packaging, wherein at least one guide member 2 is spring-loaded approximately perpendicular to a movement path 3a, 3b or is resiliently shaped. The spring effect of Guide parts 2, in particular insertion 8 or 12 snickering or the expeller 10b or trigger 28 achieved by correspondingly flexible connections 13 to the housing 14. The dispensers 1 are inserts for tool carriers 16a, such as magazines 16b, suitcases, tool trolleys, bags, belts, walls, cases, etc. The dispensers 1 are wholly or partially formed by formations of these tool carriers 16a. Furthermore, the dispensers 1 are connected to the tool carriers 16a via hinges, which are salvaged by gravity. These tool carriers 16a have receptacles 20a for the dispenser 1. In addition, these recordings are 20a either chessboard-like or cascade-shaped to each other or arranged diagonally next to each other. Alternatively, these receptacles 20a consist of shafts 20b with substantially parallel side walls, these side walls 20b having at least one end projections 20c and these projections 20c incisions 20d at regular intervals and wherein these shafts 20b optionally in the lid of a tool box or in a tray 35th are located.

Furthermore, it is provided that these tool carriers 16a have a tubular shape or approximately tubular shape. In this case, the dispenser 1 are covered by a common front 21, the front 21 having the insertion aids 8 and the receptacles 20a and formed the stop members 9 and the Bitfutterabweiser 11 forms. The dispensers 1 have connecting parts 22 for attachment to each other or to the receptacles 20a. The connecting parts 22 each form a positive and negative form on the dispensers 1 opposite each other, optionally located on the right and left, up and down, rear or front on the dispensers 1, optionally having a dovetail rail form, a round rail form or a tenon-groove form on or are designed as push buttons.

The dispenser 1 or the tool carrier 16a has at least one planar three-point support 34 in the working position and at least one two-point system 15 approximately at right angles to the same. Alternatively, the dispenser 1 or the tool carrier 16a have a substantially round shape, the center axis of which is approximately identical to the pivot axis. Again alternatively, the dispenser 1 or the tool carrier 16a have fastening means 23 which can fix them to the lower, upper or background, optionally in front of a table edge 32 or in front of a vertical beam, a column or the like. In this case, the dispenser 1 or the tool holder 16a is optionally pivotable about at least one axis and arrettierbar, displaceable in at least one plane and mounted via Parallelogrammarme, via a scissors extractor, via a linear guide or two arms on the fastening means 23, wherein the two arms each have joints with a vertical pivot axis at their ends.
