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. The best known embodiments are e.g. Ring spanners, open-end wrenches, socket wrenches, screwdrivers or the like. It is often possible to cover a large number of tool functions, in particular screwdriving tool functions, with a socket wrench assortment. For this purpose, the socket wrenches and their tool heads or tool accessories are offered in different sizes and combinations. Often there are also extensions, contra-angles or cardan joints for the function and application extension of a socket wrench assortment.

To reduce the production costs and to reduce the required accommodation space and thus the space required in a workshop screwing, especially torque tools, often separated Tool heads or essays and operating levers or even handles made. 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 site where the tools are used.

In most known from the prior art variants 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 fall out on a slippery surface or during transport.

For example, is from the DE 10 2006 055 195 A1 a storage device for bits is known, in which a Bitaufnahmereihe is pivotally mounted in a housing, whereas in this bit box no housing of a complete range of socket wrench is possible.

To remedy this create from the prior art known tool boxes, the expensive clamping devices or fixation devices for holding the working heads have. The disadvantage here again is that the space of such a range box increases by the additional features.

From the DE 10 2008 037 009 A1 a tool box is known in which a Bitaufnahmereihe is brought from a storage position in a removal position by the action of a spur gear teeth when opening the tool box.

Furthermore, from the DE 10 2004 036 228 A1 a Bitaufnahembox known, are stored in the Bitaufnahmereihen by the action of a resilient pivoting element from a storage position in a removal position pivotally.

Starting from the prior art, it is an object of the present invention to provide a tool box, which has a compact Baubaumabmaß at at the same time, good access to the tool assortment contained in the toolbox.

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

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

The tool box according to the invention for fixed-position mounting of hand tools and their accessories, in particular socket wrench, socket wrench inserts, socket wrenches, screwdrivers and / or torque wrench has two trough-shaped rectangularly configured housing parts, each with a front, a back and two long sides. The long sides are designed to be longer than the back and the front. The housing parts are pivotally coupled to one another about a pivot axis in the region of the back side and can be locked in the closed state via a closure device.

In one of the housing parts a Bitaufnahmereihe is rotatably mounted, wherein the Bitaufnahmereihe is coupled with a resilient actuator such that the Bitaufnahmereihe is rotatable from a closed position with the toolbox closed in a removal position at least partially open tool box.

According to the invention, the axis of rotation of the bit receiving row is oriented orthogonally to the pivot axis of the housing parts. This results in the advantage that the space utilization of the tool box is optimized. The void, which is in the closed state between the individual components of the tool assortment, is minimized by the inventive arrangement of the axis of rotation to the pivot axis. In the context of the invention, a bit pick-up series is to be understood as meaning a substantially elongated pick-up device into which the plug-in bits can be inserted. It is also possible in the context of the invention that the plug-in bits are plugged. In the bit recording series So it is a pivotable bank, in which several plug-in bits are arranged side by side.

In a preferred embodiment of the tool box 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. The housing parts are pivotally engaged via recesses and lugs on the disk bodies. Between the disk bodies, a pivot member for receiving a hand tool is incorporated. When the toolbox is closed, the hand tool is in a storage position. By opening the tool box, the pivoting element is also pivoted, so that the hand tool can be brought into a removal position. This removal position is already reached at least partially open tool box. In the context of the invention it is also conceivable to insert two hand tools in the pivoting element. The hand tools are, for example, a torque wrench itself or a socket screwdriver.

The Bitaufnahmereihe is rotatable during a closing movement of the tool box by the hand tool from the removal position into a closed position. During the closing movement of the hand tool in the area, for example, his hand or his tool head with the Bitaufnahmereihe comes to the plant. Due to the further closing movement of the tool box, the bit recording row is rotated into its closed position by the positive-locking contact between the hand tool and the bit recording row. As a result, an optimum space utilization of the available storage space for a squeeze assortment with a closed tool box is set.

In a further advantageous embodiment of the present invention, two Bitaufnahmierhen are rotatably coupled to the housing lower part, wherein the Bitaufnahmereihen have opposite directions of rotation. This is to be understood that extend in the longitudinal direction of the housing lower part, the respective axes of rotation of Bitaufnahmereihen. The Bitaufnahmereihen can thereby each pivot in opposite directions of rotation by opening the tool box in a removal position. According to the invention, this provides the advantage that the Bitaufnahmereihen each allow optimal access to the individual plug-in bits without a fitter accidentally attacks, for example, in the wrong Bitaufnahmereihe. Another resulting advantage is the further efficient utilization of the available storage space for the socket wrench assortment with the tool box closed.

In a further preferred embodiment variant, the spring-elastic adjusting element is designed as a spiral spring, wherein the spiral spring acts between the lower housing part and the Bitaufnahmereihe. When you open the tool box thus the Bitaufnahmereihe is placed by the spring force conditional in the removal position. The coil spring biases the bit picking row with a landing force transmitted by a torsional moment produced by the clamping of the coil spring under bias between the housing bottom and the bit picker.

Particularly preferably, the spiral spring at the end of Bitaufnahmereihe is arranged in the region of the rotatable mounting. This in turn brings particularly production-technical advantages, since a simple and cost-effective assembly of lower housing part with Bitaufnahmereihe is possible. For this purpose, the coil spring particularly preferably has an extension at its ends, wherein the extension on the lower housing part, particularly preferably on a recess or guide in the housing base comes to rest and the second extension of the Bitaufnahmereihe, particularly preferably also here in a recess or receiving device for Plant comes.

In a further particularly preferred embodiment of the present invention, the hand tool comes with closed tool box with the Bitaufnahmereihe to the plant. As a result, the hand tool experiences an additional positional fixation in a receiving position in the pivoting body, so that it is further secured in the closed state of the toolbox by the form-fitting contact between the hand tool and the bit holder row. As a result, the sockets range remains in the housing parts provided recording places even in the event that, for example, the tool box accidentally dropped. The hand tool is particularly preferably with his handle itself to the Bitaufnahmereihe bit holder rows to the plant.

In the event that two Bitaufnahmereihen are arranged in the tool box, a particularly advantageous embodiment of the present invention is that the two Bitaufnahmereihen are coupled together via a tension spring. When the tool box is opened, the tension spring sets the bit pick-up rows to the removal position. For this purpose, the tension spring is particularly preferably arranged on the Bitaufnahmereihen in a position which has the greatest possible distance from the axis of rotation of Bitaufnahmereihen. The tension spring can be, for example, a helical spring, a rubber spring or a similar spring which transmits a tensile force. Particularly advantageous in the embodiment with the tension spring is the everyday practical handling of the tool box. Due to the tension spring the erection mechanism is particularly immune to contamination or even tilting, so that always the erection function of the bit holder row is ensured.

Preferably, the tension spring comes in a closing movement of the tool box with the hand tools and / or the pivot element in positive contact. In the context of the invention, this is to be understood by the fact that the tension spring is lowered during the closing movement of the tool box by the positive contact with the hand tool and / or the pivoting element such that the bit recording rows can be converted into the closed position. This in turn also has a positive effect on the everyday handling of the toolbox, since an arrangement according to the invention via the tension spring is particularly insensitive to contamination, wear or other failure criteria.

In a further advantageous embodiment, the tension spring is arranged on the Bitaufnahmereihen such that in the closed state of the tool box, the hand tool is fixed in position in the pivotal element. This in turn results analogously to the advantages that closed tool box, the hand tool is safely stored and in case of accidental dropping or accidental impact on the tool box always a correct fit of the socket wrench assortment is given in the tool box itself.

In a further preferred embodiment, the housing parts of the toolbox each have a two-component construction, wherein the two-component structure of a soft component and a hard component and the disk body is formed from the hard component itself. In conjunction with the entire handling improvement of the tool box according to the invention, this has the particular advantage that the tool box can be turned off even on inclined planes. Furthermore, the open or closed tool box is particularly graspable by the respective fitter so that he will not slide out of his hands.

In a further preferred embodiment of the present invention, the bit holder row is extended to one side such that it is formed as a protective cover on the resilient actuator and also serves as a stop point. The attachment point is characterized in that it defines both the closed state and the opening or removal state of the bit holder row. The respective end stop is formed by a receiving bearing in the housing part for receiving the Bithalterreihe with. The extension comes to the form-fitting concern with the receiving camp.
