Description

Toolbox

The invention relates to a tool case according to the preamble of claim 1 for positionally accommodating a hand tool and its accessories.

Hand tools, in particular spiral hand tools, are manufactured and utilized in various different embodiments in practice. The most well-known embodiment is for example a plum wrench, an open end wrench, a socket wrench, a screwdriver or the like. It is often possible that many tool functions, especially the screw tool function, are met with a socket wrench kit. To this end, socket wrenches and their tool heads or tool fittings are available in different sizes and combinations. In addition, there are usually extensions, angle irons or universal joints for expanding the function and use of the socket wrench kit.

In order to reduce manufacturing costs and to reduce the required installation space and thereby reduce the space requirements in the workshop, spiral tools, especially torsion tools, are often made separately from tool heads or kits and levers or handles. The most widely used form of sale is typically a set of tool heads and matching levers or additional handles in a tool box. In use practice, such kit components are typically carried to the respective work or assembly location where the tool is used.

However, in the embodiment of the toolbox, which is generally known from the prior art, the disadvantage is that the individual tool heads or the handles themselves can only be removed from the tool box in a laborious manner or can be stored loosely, so that they are therefore tilted in the toolbox. On the basis of or fall out during transportation.

A holding device for a cutter head is known, for example, from DE 10 2006 055 195 A1, in which a cutter head receiving row is pivotally supported in a housing, but instead, the entire sleeve cannot be placed in the cutter head storage box. Cartridge wrench kit.

Remedies are achieved by some tool kits known from the prior art, which have complex clamping devices or fixtures for holding the working head. The disadvantage here is that the structural space of such a kit storage box is increased by additional functions.

Starting from the prior art, it is an object of the present invention to provide a tool case that has a compact structural space size while providing good access to the kit located in the tool case.

The above object is achieved by a tool case having the features of claim 1 for positionally accommodating the hand tool and its accessories.

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

The tool case of the present invention is suitable for positionally receiving a hand tool and its accessories, in particular for positionally accommodating a socket wrench, a socket wrench insert, a socket wrench set, a screw tool and/or a torque wrench, The toolbox comprises two housing parts that are configured in the form of a basin and a rectangle, each having a front side, a rear side and two longitudinal sides. The two longitudinal sides are respectively formed longer than the front side and the rear side. The two housing parts are pivotally coupled to one another in the region of the rear side about a pivot axis and can be locked in the closed state by means of a locking device.

Rotatingly supporting a bit-receiving row on one of the housing parts, the bit-receiving row being coupled to the spring-elastic adjusting element such that the bit-receiving row can be rotated from a closed position when the toolbox is closed to The extraction location when the toolbox is at least partially open.

According to the invention, the axis of rotation of the bit holder row is perpendicular to the pivot axis of the housing part. Therefore, the advantage is obtained that the structural space of the toolbox is fully utilized. The free space between the various components of the kit in the closed state is minimized by the arrangement according to the invention of the rotational axis relative to the pivot axis. Within the scope of the invention, a substantially elongated storage device is understood for the bit storage row into which the plug bit can be inserted. It is also possible within the scope of the invention for the plug head to be fitted. The cutter head storage tray relates to a pivotable long pedestal in which a plurality of plug cutter heads can be arranged side by side.

In a preferred embodiment of the toolbox according to the invention, on the rear side of the two housing parts, a partially circular disk body is integrally formed in the extension of the side walls of the respective longitudinal sides. The two housing parts are pivotally engaged via a gap and a projection on the disk. A pivoting element is mounted between the discs for receiving the hand tool. When the toolbox is closed, the hand tool is in the storage position. By opening the toolbox, the pivoting elements are also pivoted together so that the hand tool can enter the extraction position. This extraction location has been reached at least partially when the toolbox is opened. It is also conceivable within the scope of the invention to insert two hand tools into the pivoting element. These hand tools are, for example, a torque wrench itself or a socket wrench type screwdriver.

In a preferred embodiment, the bit holder row can be rotated from the extraction position to the closed position by the hand tool and/or the pivoting member during the closing movement of the tool case. During the closing movement, the hand tool is in contact with the bit holder row, for example in the region of its handle or its tool head. Through the continued closing movement of the tool case, the bit holder row is rotated to its closed position by the form-locking contact between the hand tool and the bit holder row. Therefore, in the closed toolbox, the optimized space for the storage space provided by the socket wrench kit is fully utilized.

Furthermore, within the scope of the invention, the aforementioned rotational movement can be achieved by the form-fitting engagement of the pivoting elements on the bit holder row. For this purpose, for example, a continuation is formed on the pivoting element, which continuation engages the tool magazine. Instead, not only the hand tool but also the pivoting elements can be joined together in a form-fitting manner with the cutter head. For example, it is conceivable to form a kinematic form-locking sequence such that, for example, a partial turning of the bit holder row is first performed by the pivoting element itself, and a final roll-off is achieved by means of a hand tool for the bit holder row. Enter the closed position.

In a further advantageous embodiment of the invention, the two bit holder rows are rotatably coupled to the lower housing part, the two bit holder rows having opposite directions of rotation. It should be understood that the axes of rotation of the respective bit holder rows extend in the longitudinal direction of the lower housing part, respectively. The respective cutter head rows can be pivoted to the extraction position by opening the toolbox in opposite rotational directions. According to the invention, the advantage is achieved in that each of the bit-receiving rows respectively allows an optimized access to the individual plug-type inserts, without the assembler, for example, unintentionally projecting into the wrong bit-receiving row. Another advantage obtained is the additional effective utilization of the storage space provided by the socket wrench kit when the toolbox is closed.

In a further preferred embodiment, the spring-elastic adjusting element is embodied as a coil spring which acts between the lower housing part and the bit holder row. Therefore, when the toolbox is opened, the cutter storage tray stands by a spring force to an extraction position. The coil spring loads the head storage row with a standing force which is transmitted by a torsional moment which is established by clamping or mounting the coil spring with a preload between the lower housing part and the bit holder row.

It is particularly preferred that the coil spring is arranged in the region of the rotatable bearing point at the end of the bit holder row. This in turn achieves a particular advantage in production technology, since the lower housing part and the bit holder row can be assembled in a simple and inexpensive manner. In particular, the coil springs have a continuation at their ends, which continuation is applied to the lower housing part, particularly preferably to the recess or guide in the lower housing part, and the second continuation part is attached. Close to the bit holder row, it is particularly preferred to also fit in the gap or receiving means.

In another particularly preferred embodiment of the invention, the hand tool is in close contact with the bit holder row when the toolbox is closed. In the closed position of the tool case, the hand tool is additionally fixed in the closed state of the tool case by the form-locking contact of the hand tool with the bit carrier row. Thus, for example, in the case of a toolbox unintentionally falling, the socket wrench kit is also held in a receiving position set in the two housing parts. In this case, the hand tool preferably has its handle itself attached to the cutting head row of the cutter head row.

In the case of providing two bit holder rows in a tool case, a particularly preferred embodiment of the invention consists in that the two bit holder rows are coupled to each other by a tension spring. The tension spring causes the cutter storage row to stand to the extraction position when the toolbox is opened. For this purpose, the tension spring is particularly preferably arranged at a position on the bit holder row which is as far apart as possible from the axis of rotation of the bit holder row. The tension spring can be, for example, a coil spring, a rubber spring or a spring that transmits a tensile force. In an embodiment with a tension spring, the daily practice of the toolbox is particularly advantageous. By means of the tension spring, the standing mechanism is particularly resistant to dirt or skew, so that the standing function of the cutter head row is always guaranteed.

Preferably, the tension spring is in positive-locking contact with the hand tool and/or the pivoting element during the closing movement of the tool case. For this purpose, it should be understood within the scope of the invention that the tension springs are lowered by the form-locking contact with the hand tool and/or the pivoting element during the closing movement of the tool case, so that the respective head storage rows can be moved to the closed position. . This in turn advantageously affects the day-to-day operation of the tool case, as the structure of the tension spring of the present invention is particularly susceptible to dirt, wear or other failure factors.

In a further advantageous embodiment, the tension spring is arranged on the cutting head receiving line in such a manner that the hand tool is in a positively locking position in the pivoting element in the closed state of the tool case. Therefore, the advantage is similarly that the hand tool is reliably stored when the tool box is closed and the socket wrench kit is always correctly in the tool box when the tool box is inadvertently dropped or unintentionally subjected to impact. In place.

In a further preferred embodiment of the invention, the two housing parts of the tool case each have a double-component structure comprising a soft component and a hard component, the disk body being composed of a hard component Partial composition. A special advantage is thus produced in conjunction with the overall operational improvement of the toolbox of the invention, that is, the toolbox can also be parked non-slip on an inclined plane. In addition, the open or closed toolbox can be gripped particularly by the assembler who uses it accordingly, so that the toolbox does not slip out of his hand.

In a further preferred embodiment of the invention, the bit holder row is extended to one side such that the bit holder row is formed as a protective cover over the spring-elastic adjusting element as a stop point. The stop point is characterized in that it not only defines the closed state of the cutter head support row, but also defines the open state or the extracted state of the cutter head support row. In this case, the respective end stop is formed by a receiving support for receiving the row of carrier heads in the housing part. The extension is in a positively locking manner with the receiving support.
