Description

The present invention relates to a tool box for fixed-position mounting of hand tools and their accessories according to the features in the preamble of claim 1.

Hand tools, in particular screw hand tools are manufactured and used in practice in various embodiments. Often it is possible to cover a variety of tool functions, in particular Schraubwerkzeugfunktionen with a Steckschiüssetsortiment, For this purpose, the socket wrench and its tool heads or tool accessories in different sizes and combinations offered. There are also extensions, contra-angles or cardan joints for the functional and application expansion of a socket wrench assortment.

In order to reduce the manufacturing costs and to reduce the required accommodation space and thus the space required in a workshop screwing, especially torque tools, often made separately from tool heads or attachments and operating levers or even handles.

The most common form of distribution is generally a certain set of tool heads with associated operating lever or even another handle within a tool cassette. In practice, such an assortment set is often carried to the respective work or assembly location where the tools are used. In most known from the prior art embodiments of tool boxes, however, this results in the disadvantage that the individual tool heads or even the handles themselves are only cumbersome removed from a tool box or are stored so loosely that they sometimes when you turn off the tool box to fall out on a slippery surface.

To remedy this create from the prior art known tool boxes, the expensive clamping devices or fixation devices for holding the working heads have. For example, is from the DE 10 2006 041 564 A1 a tool box known in which two housing halves are pivotally connected to each other. The disadvantage here again is that the space of such a range box increases by the additional features.

From the CN 200948588 Y a tool box is known in which two housing parts are coupled together via a pivoting mechanism incorporating a pivoting element. During opening movement, a bit recording row is pivoted into a presentation position. A similar embodiment is from the US 2008/0041746 A1 known. Furthermore, from the DE 92 05913 U 1 , of the DE 10 2006 041 564 A1 as well as the DE 87 02 332 U1 Tool boxes known in which two housing parts are pivotally coupled together.

Starting from the prior art, it is the object of the present invention to provide a tool box, which has a compact space dimension and a high degree of robustness and is also easy to install.

The above object is achieved with a tool box for fixed-position mounting of hand tools and their accessories with the features of claim 1.

Advantageous embodiments of the present invention are part of the dependent claims.

The tool box according to the invention is suitable for fixed-position mounting of hand tools and their accessories, especially sockets, sockets, sockets, screwdrivers and / or torque wrenches. In particular, this is the toolbox assortment components of a socket wrench assortment to understand, which are divided into torque wrench, screwdriver handle, nuts, extensions, Kaderneinsatz, reducers and plug-in bits.

The tool box according to the invention consists of two trough-shaped, rectangularly configured housing parts, each having a front side, a rear side and two longitudinal sides, wherein in each case the longitudinal side is formed longer than the front side or the rear side. This is to be understood that the longitudinal sides of the longitudinal legs of the rectangular shape and the front and back form the shorter legs of the rectangular shape. The housing parts are pivotally coupled to one another in the region of the rear side and can be locked in a closed state via a closure device. The closure device sits in particular in the area of the front side. But it can also be attached to the side panels. The tool box according to the invention is thus coupled to one another via one of the shorter sides in a pivotable or hinged manner.

According to the invention, circular-segment-shaped disk bodies are integrally formed in the extension of side cheeks of the longitudinal sides on the rear sides of the housing parts, and the housing parts are pivotably engaged via recesses and lugs on the disk bodies. Through the recesses and lugs on the disk bodies, a hinge function is thus formed in the region of the disk body, via which the tool box can be folded or swiveled. The pivoting movement is carried out to open or close the toolbox. The tool box according to the invention is thus hinged along its longitudinal axis, which brings in the field of storage, for example, in a drawer or even putting up at a mounting extreme handling advantages.

The tool box according to the invention has circular-segment-shaped disk body, which project beyond the side cheeks in height, preferably by 1.5 - 2 times. In the trough-shaped housing parts side cheeks are formed on the longitudinal sides, which are integrally transferred into the disk body From the transition region to the disk body, the side wall thus rises and is preferably 1.5 to 2 times higher than the side wall itself. With folded tool box thus cover the disk body in about the entire height of the tool box itself, since they have approximately the height of 2 times the side wall. Thus, the height of the folded toolbox corresponds approximately to twice the side wall or substantially the height of a disk body,

The hinge function formed by the disk bodies is thus utilized optimally under the aspects of installation space and the folding function. At the same time, the disk body has a particularly robust and also non-vulnerable folding mechanism which, on the one hand, allows a long service life and, on the other hand, a fail-safe handling of the toolbox.

The tool box according to the invention is preferably made of a plastic material. This offers the advantage that it is inexpensive to produce and at the same time has a long service life expectancy. The production in particular of the housing parts with the disk bodies made of plastic also allows easy installation while maintaining a firm and secure fit and high security against failure of the hinge. Also, in the case of manufacturing the tool box made of plastic, the tabs and recesses are made of plastic, whereby a sliding fit is formed in the hinge function.

In a further preferred embodiment, the disk bodies are formed in an angular range of 250 and 290 degrees. This means that a circumferential body, which is similar to a unit circle, is integrally formed at an angle range between 250 and 290 degrees at one end of the side cheek of a longitudinal side. With respect to the respective cover side of a housing part of the unit circle begins and thus continues in a rotary motion, so that in each case a survey on the longitudinal side is formed to the closed tool box interior.

The disk body of a lower housing part each have a round recess, wherein the recess is arranged in the center of the disk body. Furthermore, the disk body of a housing upper part each have a round nose, wherein the nose is arranged in the center of the disk body and can be inserted into the recess of the disk body of the housing base. Consequently, there is a hinge function on the engaging in the recess nose. The arrangement of both the nose and the recess in each case centrally in the disk body results in a closed toolbox between the upper housing part and the lower housing part lying between the upper housing part and the housing part pivot axis, Again, this arrangement of the pivot axis offers again the advantage that a compact Baubaumabmaß with the tool box according to the invention is achieved. About the disk body is a very robust coupling or connection between the hinge function and the housing itself. A defect of the tool box, for example, by a housing break in the region of the hinge is thus largely avoided.

In an advantageous embodiment, the lugs and / or the recesses locking nubs, with which the pivotal movement of the housing parts in different positions can be locked. These locking knobs can be done for example in the form of a positive engagement or even an engagement of a flattened gear. These locking knobs make it possible to lock the opening or closing movement, that is to say the pivoting movement of the toolbox, in various positions. For example, at an opening angle of 90 degrees, so that access to the socket set contained therein is possible, with only a compact storage option is given, Another advantage of a locking function is z. As can be seen in the fact that it sometimes makes sense in different working positions when a part of the creak box is vertical, so that it can be accessed. Another advantage is that both the lower housing part and the upper housing part can then be arranged at an angle to the respective Abstellort. Particularly preferably, in a mounted state of both housing parts, the disk body of the housing upper part is arranged on the inside and the disk body of the housing lower part is arranged on the outside. This has the particular advantage that the lower housing part can remain lying on the Abstellort and the upper housing part is pivoted. Furthermore, it is thus possible to assemble the toolbox particularly inexpensively and easily during initial assembly.

In at least one disk body is provided at least partially around the nose and / or recess circumferential groove, said predetermined by the groove inner portion of the disk body with the nose and / or the recess forms a locking function. The area enclosed by the groove thus forms the function of a latching tongue or else a spring bar. As a result, it is possible, especially during the initial assembly, to connect the two housing parts to one another in such a way that the lugs engage over the latching lug.

The hinge function is thus clipped into each other with a kind of clip function. This also offers the advantage that in the case of a partial defect by means of a replacement part, for example a new housing upper part, the tool box according to the invention can be easily maintained or repaired. In the event that contaminants have entered the hinge function, it is thus possible for the respective applying installer of the tool box to maintain this by quick disassembly and reassembly.

The housing parts of the tool box according to the invention particularly advantageously each have a two-component structure of a soft component and a hard component, wherein the disk body are formed on the hard component. The two-component construction of the respective housing parts thus offers, in particular, the possibility of direct position fixing of the socket wrench assortment in the housing parts themselves. Furthermore, a soft component on the outside of the tool box offers a particularly good handling possibility or even storage possibility, since the tool box is thus prevented on a substrate from slipping or slipping out of one hand. The formation of the disk body on the hard component provides again the advantage that the hinge function is integrated directly into the manufacturing process of the housing parts themselves and then by simply plugging the housing parts of the tool box is already completed ready for use.

Between the disk bodies, a pivoting element is rotatably mounted in the mounted state, wherein the pivoting element is incorporated between the disk bodies. The pivoting element thus provides in the hinge function and also the back part or the back side of the tool box according to the invention a sealing function, so that here in the closed, partially open or even open state no dirt can penetrate into the tool box itself or in the hinge function.

Furthermore, the pivoting element may be designed in the form of a container, so that here storage options for small parts further recording options for tools, accessories o. Ä. Can be formed. The pivoting element also has the function of a locking pin. The trained locking tongues or even locking lugs between the recesses and the lugs themselves are further reinforced by the inserted pivot element, so that an unintentional unfolding of the tool box is prevented in its individual parts. Furthermore, this increases the longevity and robustness of the hinge function.

The pivoting element is configured as a two-part roller body, wherein a back part and a receiving part are formed and share the cylinder substantially along its central longitudinal axis. The cylinder is thus particularly easy to produce, since essentially two half-shells in the form of two each semi-circular cylinder-section-shaped bodies is formed. The two bodies are in turn inserted into each other, for example via connectors, and are thus either individually mounted between the housing parts or as a mated roll body.

For the arrangement between the disk bodies of the two housing parts, at least one of the cylinder-section-shaped body has cams. Particularly preferably, the cams are formed on the back part, wherein the cams turn come in recesses of the disk body for positive engagement. Preferably, the recesses are formed within the lugs of the housing upper part. This in turn offers the advantage according to the invention of making the hinge particularly compact and simple, so that it is robust, durable and easy to produce. Furthermore, this offers the advantage that in the case of the upper part of the housing formed locking lugs these are so fixed in position after assembly of upper housing part and lower housing part, that disassembly of the toolbox can be carried out only by removal of the pivoting element.

In a further advantageous embodiment variant, longitudinal slots extend from the cams, so that in turn here too a spring bar is formed in the side surfaces. The cams are then arranged at the free end of the spring bar. This, in particular, offers production-related advantages, so that a particularly easy-to-carry initial assembly of the toolbox is possible, whereby a firm and secure seat of the hinge function is always given by the elastically deforming spring bar.

The pivoting element itself has receptacles for hand tools, wherein the receptacles are preferably formed in the receiving part. This offers the possibility, for example, to use a torque wrench itself or a handle in the receptacles of the receiving part. In the case of a pivoting movement of the toolbox thus again creates the advantage that the tools in the receiving opening by a pivoting movement of the pivoting element can be brought into a Präsentierstellung and thus are easily removed.
