EP0270845B1 - Shop-storage means for tools with a clamping shaft, in particular screw-driver bits - Google Patents

Abstract

The shop-storage means consists of a middle box and of one or more tool magazines (27), especially bit magazines, fastened laterally to the middle box. Each tool magazine (27) contains a series of individual magazines (28) arranged parallel to and at a distance next to one another, each individual magazine forming a receiving space for tools (29, 30), for example bits, mounted above one another in stack form. These tools in the receiving space rest on a spring plate (40) supported relative to the bottom plate (13) by means of a spring (41), the spring length of which is great enough to ensure that even the lowest tool resting on the spring plate (40) can be extracted via an upper end extraction orifice (32). For extraction, the tool can be pushed out forwards through the end orifice (32) by way of an upper slot (34) in the individual magazine (28), the next tool following up as a result of the spring plate (40). <IMAGE>

Description

The invention relates to a sales magazine according to the preamble of claim 1.

From DE-A-3 146 452, cuboid-shaped drawer cassettes for tools are known, each consisting of a housing and a drawer, which can be stacked one above the other to form a tool cabinet. The side walls of the cassette housing have dovetail grooves, to which insertable clamps are assigned, by means of which two drawer cassettes one above the other can be connected to one another. Different tools can be sorted there per drawer, but this arrangement is not sufficient in view of the large number of tool types and sizes, e.g. if all marketable bit types should be ordered discretely, as is required in particular in sales magazines.

Furthermore, sales magazines for bits in the form of tool boxes are known, in which a plastic deep-drawn part with molded receptacles for in a box a magnet holder, a screwdriver and various bits is arranged. The disadvantage of this design is that only a very limited number of bits can be accommodated in these plastic inserts, since only one bit can be inserted into each receptacle. Another disadvantage of the known design is that the bits are only to be sold there in connection with the ratchet and the magnet holder, which is often not desired by the customer.

A magazine for the presentation of individual bits with an additional compartment for screwing tools is known from EP-A-0 155 996. There, several bits are arranged in cylindrical individual magazines provided with individual receptacles along their cylindrical surface. Each individual magazine is closed at the end by a rotatable cover, which is provided with a removal opening which can be aligned in each case via the bit to be removed. This known bit magazine has large, unused dead spaces, so that it is unsatisfactory in terms of its storage capacity. In addition, its assembly and removal are cumbersome.

Furthermore, a magazine is known from FR-A-2 042 210, which consists of stackable, shaft-shaped individual magazines. Each individual magazine holds stacked containers that have a protruding edge on the bottom. The housing of each individual magazine has an opening at the top for partial passage of the uppermost container, which, however, engages under the edge of the housing opening with its projecting edge. By one under the Stack of the spring arranged containers, the containers are each raised so far in the single magazine that the uppermost container partially protrudes through the opening from the single magazine. In this position, the uppermost container can be removed from the individual magazine through a removal opening provided on its end face and adapted to the width of the protruding bottom edge. This known magazine is very complex in its construction because of the special containers required. Since the tools have to be removed again from the containers when they are used for tools, for example bits, their handling is also cumbersome.

The invention has for its object to design the sales magazine according to the preamble of claim 1 with a simple construction in terms of production technology, so that on the one hand the greatest possible selection of tool inserts, e.g. Bits that can be offered in the smallest possible space, but on the other hand, the removal of the tools at the place of use is made easier.

To achieve this object it is provided according to the invention that on one or both sides detachable side boxes designed as tool magazines are arranged on a center box, on which receptacles for a tool ratchet and for a magnet holder are provided, that in each tool -Magazin a series of shaft-like individual magazines are arranged side by side in parallel, in which the tools are stacked in rows on a spring plate, the spring plate being spring-loaded in the vertical direction in the Individual magazine is displaceable, that each individual magazine has a slot on its top surface that points in the longitudinal direction of the tools, the width of which is smaller than the width of a tool, and that each individual magazine is assigned a removal opening arranged on the top side of its front, which has each tool on the end wall -Magazin in the area of the upper end of the narrow surface of each individual magazine is arranged such that the tools can be removed from the individual magazine through the removal opening.

A significant advance is achieved by the invention, because by stacking tools one on top of the other in shaft-like individual magazines, with a large number of individual magazines being arranged in parallel in a tool magazine box, there is the advantage that a large number of can be found in a small space Can arrange tools. Tools of the same size are preferably stored for each individual magazine. However, each individual magazine can also contain tools of different sizes. Nevertheless, the tools are easy to remove, since the tools are stacked on top of each other in each individual magazine and the bottom tool is carried by a spring plate, whereby the spring travel is so large that all tools are lifted so far that they are removed one after the other via the upper, front removal opening can be. It proves to be particularly advantageous for handling that each individual magazine has at the top on its top surface a slot pointing in the longitudinal direction, the width of which is less than the width of one Tool. The uppermost tool can be loaded through the slot, for example with a finger, and pushed out or pulled out through the front removal opening.

Since the tool magazines are detachably connected to the center box, there is the advantage that the tool magazines can also be sold individually without having to buy the center box. A preferred embodiment of a tool bit magazine which can also be used by itself is specified in claims 8 to 10, for which independent protection is claimed.

With the arrangement described, a large number of tools of different sizes are therefore easy in a confined space presented removably.

The subject matter of the present invention results not only from the subject matter of the individual claims, but also from the combination of the individual claims with one another.

The sales magazine 1 according to the illustrations consists of a center box 2, which is designed as a plastic injection molded part. This has all-round walls, an open bottom side and an upper cover side, in which a receptacle 10 for a magnet holder and a receptacle 11 for a ratchet are molded.

The two parts mentioned (magnet holder and ratchet) are thus inserted into the upwardly open receptacles 10, 11.

The center box 2 is here formed in two parts and consists of a base part 8 and a cover 9 which can be snapped onto the base part 8, a latching connection 12 arranged on two sides of the base part 8 connecting the cover 9 to the base part 8.

Instead of the latching connection between the base part 8 and the cover 9 described, a hinge connection between the cover and the base part can also be provided. Both a film hinge and a hinge formed separately from it are possible; it is also possible that the cover 9 with corresponding associated guides on the bottom part 8 is displaceable so that it can simply be pushed onto the bottom part and pushed off again.

The lid preferably consists of a crystal-clear plastic material, while this is not necessary for the plastic material of the base part.

1 and 3, dovetail guides 6 are integrally formed on the side of the center box 2, wherein lateral tool magazines, in the exemplary embodiment shown bit magazines 3, 4, are releasably inserted into these dovetail guides.

This arrangement has the essential advantage that the bit magazines are interchangeably arranged on the center box and thereby bit magazines of different sizes and different numbers of individual magazines 5 can be attached to the center box 2.

Instead of using 2 identical bit magazines 3, 4, it is also possible to design the center box in such a way that only a single bit magazine is attached; here the bit magazine could be pushed onto the back of the center box, for example.

The dovetail guides on both sides of the center box are designed so that it is also possible to detachably connect the two bit magazines 3, 4 directly via the dovetail guides arranged there, the center box 2 then being removed.

In a further development of the present invention, it can be provided that, for example in extension to the end faces and the rear sides of the respective bit magazine, an upwardly projecting tab is formed, in which a standardized opening is made, so that the bit magazines are attached individually Sales vehicles can be attached to ensure a better performance in the sales market.

It is also possible to attach flaps shaped in this way and projecting upwards to the middle box 2.

Each bit magazine 3 consists of a base plate 13 which is connected to the end wall 18 and the rear wall 19 via a corresponding adhesive or welded connection. Since the base plate 13 is connected to the rest of the housing only after installation of the springs 14 and is thus already exposed to the high total pressure of all the springs 14, the connection is preferably made by ultrasonic welding.

Individual magazines 5 are defined between these two walls 18, 19, specifically by side walls 15, 16 arranged in parallel and mutually spaced apart, each of which forms a receiving space 23 in which the bits 20 are stacked one above the other.

It is important that a spring plate 17 is arranged in the receiving space 23, which rests on the base plate 13 with one or more springs 14 supported and this spring plate 17 is arranged in the receiving space 23 so as to be displaceable in the vertical direction, the length of the springs 14 being dimensioned such that that the last bit resting on the spring plate 17 can also be removed through the upper removal opening 21.

The single magazine 5 is pierced at the top of its top surface by a slot 22, on the front and rear sides of which, as shown in FIG. 1, openings 24 which extend the slot are also arranged and which are intended to form an engagement space for the user's thumb or for other fingers, so that it is easily possible to grasp the surface of the uppermost bit 20 protruding through the slot 22 with the thumb or another finger and to push it forward in the direction of the arrow 25 out of an end removal opening 21.

With regard to the previously mentioned openings 24, which are intended to make it easier to grasp the bit 20, it is added that the openings 24 are designed in such a way that the width of the slot is only in the area of a central part 26 on the top surface of the individual Magazine 5 extends, while then the openings 24 are wider than the slot, so that then with your finger or with a designated Removal tool the bit can be removed.

It is also important that the distance between the side walls 15, 16 arranged parallel to one another is different, so that different bit sizes can be arranged next to one another in the bit magazine 3 and all bits are then accessible from above through the respectively assigned slot 22 of the individual magazine 5 and can each be pushed out through the removal opening 21 in the direction of arrow 25.

It is also important that the bit magazine 3, 4 is each made of a transparent plastic material, or that at least the front end wall 18 is made of a transparent plastic material, so that one can see from the end wall 18 side how many bits in each individual magazine 5 are arranged.

In a development of the present invention, it can be provided that the side walls 15, 16 can be plugged onto the base plate 13 and are guided in corresponding grooves on the end wall 18 and the rear wall 19, so that the distance between the side walls 15, 16 in certain Limits is adjustable.

It is then possible to use bit inserts of different widths by changing the width of the individual magazine.

The bit magazine 27 illustrated in FIGS. 6 to 13 is intended in particular for bits with a hexagonal clamping shank and can be used both in connection with a center box 2 according to FIG. 1 and independently. The bits 29, 30 arranged in rows in shaft-like individual magazines 28 can be removed in the axial direction through recesses 32 which are provided on the upper edge region of the front wall 31 and are open towards the top. Slots 34 formed in the cover 33 of the bit magazine adjoin the recesses Width in a front area 35 adjoining the recesses 26 is equal to the diameter d of the inner circle of the hexagonal shaft 36 and its width in a rear area 37 extending to the rear wall of the bit magazine is smaller than the diameter d of the hexagonal inner circle is larger than the width b of a hexagon side. The slot walls 38 are inclined at right angles to the level of the cover in the front area 35, while the slot walls 39 diverge inward in the magazine area 37 and enclose an angle of 60 ° with the cover level. The bits lie within the shaft-like individual magazines on spring plates, each of which is formed by an elongated box 40 that is open at the bottom and guided with little play in the individual magazines, in each of which engages an approximately rectangular or oval compression spring 41 in plan view, the base length X and Base width Y is approximately equal to the inside dimensions of box 40.

In the stored basic position, cf. Fig. 12 and the bits 29 in Fig. 11, the bits are pressed by the spring 41 against the diverging slit walls 39 of the rear slit area 35, the top bit protruding a bit beyond the top of the lid and thus comfortably by hand towards the front can be pushed out of the magazine. The particular advantage of the embodiment according to FIGS. 6 to 13 lies in the fact that the magazine can be easily loaded. One bit is used for this, cf. Bit 30 in FIG. 11, in a rotational orientation according to FIG. 13, that is to say with two hexagon side faces 42 of the slots 34 oriented at right angles to the cover plane and pressed against the force of the spring 41 into a magazine slot until the bit hexagon is underneath the rear, projecting into the slot slot walls 39 can be inserted. After such insertion, the inserted bit automatically rotates to the position shown in FIG. 12. after which the next bit can be entered into the magazine. The bit magazine shown is therefore particularly suitable for automatic loading.
