Description of the Invention: [Technical Field] The present invention relates to a tool case according to the feature of the preamble of claim (4) for positionally accommodating a hand tool and its accessories. [Prior Art] Hand tools, especially spiral handguards, are manufactured and utilized in a variety of different implementations. The most well-known embodiment is for example a plum wrench, an open wrench, a socket wrench, a screwdriver or the like. It is often possible that many tool functions, especially the screw-up function, are met with a socket wrench kit. For this purpose, the #1 wrench and its tool head or tool fitting are available in different sizes and combinations. In addition, there are plus ore inserts or extensions for the function and use of the socket wrench kit. In order to reduce the manufacturing cost and reduce the required installation space and thereby reduce the space requirements in the workshop, the helical tools, especially the torsion tools, are often made separately from the tool head or the kit and the lever or handle. The most extensive form of sale is the one-of-a-kind tool head and a matching operating lever or another handle in a tool box. ^ The tool box is often constructed to be openable such that it has an upper shell and a lower shell that are rotatably coupled to each other. The housing consisting of the upper and lower casings does not open undesirably, and the housing has a locking device. Such a locking device is known, for example, from DE 193 8〇32ui. The latching assembly constitutes a non-pushable connection between the upper body member and the lower housing member. It forms the form of a stop projection. Also known from the prior art is a 157372.doc 201217117 bayonet type latch or a clamped latch. A disadvantage of these latching devices is that they are manufactured. However, the set of socket wrenches is especially relevant to the locking device. In terms of cost, they can only cost the manufacturing cost, and the toolbox requires the manufacture of a particularly inexpensive locking device. However, if the locking device is manufactured in an inexpensive manner, it may be reduced: in the case of this measure. The long life or the robustness of the locking device is affected. SUMMARY OF THE INVENTION The object of the present invention is to provide a locking device that can be easily operated and can be manufactured at low cost. The above object is achieved by a work box having the features of claim i for positionally accommodating a hand tool and its accessories, the tool case comprising a latching device disposed on the tool case. Embodiments of (4) of the present invention are an integral part of the dependent claims. The guard box of the invention is used for positionally accommodating the hand guard and its accessories, in particular for fixing the socket wrench, the socket wrench insert, the socket wrench set, the screw tool and/or the torque wrench. The toolbox comprises two housing parts which are embodied in the form of a basin and a rectangle, each having a front side, a rear side and two longitudinal sides, the two housing parts pivoting in the region of their rear side The wires are pivotally coupled to each other. In addition, the two housing parts can be locked in the closed state on their front side by means of a locking device arranged there. The locking device of the present invention has a knob which is arranged on the front side in a receiving portion of the two I57372.doc 201217117 housing parts and is rotatably arranged in the first case with the spring-elastic adjusting element On the housing part. Alternatively, the red button of the present invention has a stop means 'the stop means engageable on the abutment section on the second housing part. In order to accommodate the yang, it is basically understood in the context of the invention that a gap is formed in the two housing parts: the gap essentially corresponds to the geometry of the knob in its geometrical configuration. However, in the present invention, it is also conceivable that the knob can be fitted to the two housing parts. Rotation connects the two housing parts ' so that they are locked in the closed state of the toolbox, thus preventing the toolbox from accidentally opening. The advantages of the invention are in particular the particularly simple operational possibilities of the assembly of the locking mechanism into the two housing parts and the use of the locking device. In an advantageous real money case, the rotary bearing is rotatably supported on the first housing part, and the rotation axis is substantially perpendicular to the front side: the force fit can be rotated by the knob simultaneously The Δ is pre-tensioned and then an opening movement is performed, at which point the opening movement is directed to the direction of the force which is substantially perpendicular to the holding or operating direction of the knob.

(4) H. Hard work place It is possible to use only one hand as fast as possible: and open the toolbox. The abutment section of the component is understood to be 'stop projection. In another advantageous embodiment, the second housing has a stop projection. This is within the scope of the invention 157372.doc 201217117 not only constitutes a support section, but also constitutes a stop function. Through the closure of the toolbox, the stop function ensures that the toolbox is reliably closed. The stop projection and the stop means on the knob constitute a snap function. The stop projection can here have a bevel such that by closing, the spring action of the knob against the spring-elastic adjustment element is guided via the bevel and then automatically snaps into the seat area slave. In addition, it is particularly advantageous in this case that the production technology is inexpensive, the stop projections can be formed directly during the production of the housing part. In another embodiment of the invention, the guide # can be constructed on at least one of the shell members. When the I-boxes of the invention are moved or closed, the guiding means ensure a precise positioning of the two housing parts one above the other and ensure a precisely guided closing process, so that the locking mechanism reliably engages the 0 knob here via the spring The elastic adjustment element enters the blocking position. The spring-elastic adjustment element applies force to the knob so that the knob is always in the closed position. The use of the snap function between the knob and the holder section in terms of the closing function provides the advantage that the knob always returns to its initial position, i.e. its closed position, after operating the knob. It is thus ensured that in the closed position of the knob the "I-box" is always locked and avoids undesired opening and, for example, avoids the falling of the tool. In a further advantageous embodiment, the knob has a stop lug that is operatively coupled to the first housing part and the knob is constrained by the stop bump from the closed position. Rotate all the way to the open position. The knob can therefore only be rotated over a range of angles of preferably 5 to 60 degrees, in particular 1 to 4 degrees, and the jL15 is embossed to the limiting groove. 157372.doc 201217117 guarantees that the knob does not occur Excessive rotation. The undesired damage of the spring-elastic adjusting element or the latching mechanism or the moving mechanism is thus further avoided. By reaching the open position, the assembler is tactilely notified that he can now open the toolbox. Therefore, unintentional over-opening is also avoided to the greatest extent and thus the drop of the toolbox associated with it and the simultaneous fallout of the tool are avoided. After operating the knob, the knob is again brought into the closed position by the spring force of the spring-elastic adjustment element. Therefore, the direct locking of the two housing parts is ensured during unintentional opening, or when the toolbox is opened and the closing process is followed, the latching mechanism is thus realized. The knob additionally has at least one stop tongue which engages in a slot-like manner in the first housing part. The advantage of the first assembly or complete realization of the housing of the toolbox is achieved by the locking tongue just in terms of manufacturing technology. The knob-side as a rotatable loose support is supported by a receptacle in the first housing part or by a receptacle formed by two housing parts

Within the scope of the invention, the latching tongue is in particular a stop tongue which conforms to the barb principle. On the axis, the knob is moved on the side by the stop on the housing part and on the other hand by the kinematics of the stop tongue. At the time of the first assembly, it is advantageously obtained that the screw is inserted into the first housing part, which is thus rotatably fixed in position as a loose support. It is also possible within the invention of the invention to form two stop tongues. This in particular advantageously affects the long life of the knob. Further, within the scope of the present invention, 157372.doc 201217117 = 疋, the stop tongue is rotated in the groove - straight to one end to stop broadcasting, = the movement is not limited. Therefore, the breakage of the movable tongue is avoided in the case of the permanent use of the stopper by the stop projection and the restriction groove stop tab. In the direction of the stop tongue, the knob is fixed in a form-locking manner. & The direction of rotation is perpendicular to the scope of the present invention * The support member of the support and the stop tongue is selected in the first-shell portion to involve a spiral bombardment, and the two-material (four) (four) integral component is superior to ... κ, the spring is The two flank portions of the two ends are particularly advantageously attached to the aforementioned position so that a spring action is established between the knob and the first housing part. Torsion springs or other elastomers can also be used within the scope of the invention. For example, an elastomer spring can be considered. The springs are also mounted directly during the first assembly during the manufacturing process at a low cost and are fixed by snapping into the receptacle. In a particularly advantageous manner, the spring-elastic adjusting element is surrounded by the spring body so that the adjusting element of the spring-elastic spring is held in a fixed position so that the spring force is also ensured during the perennial use of the tool case. Therefore, it is possible to avoid moving or slipping to the utmost extent and thus avoid malfunction. This in particular affects the long life of the locking mechanism of the present invention. In another particularly preferred embodiment, the knob is configured in the shape of a disk. Furthermore, it is advantageous to have a slat on its front side, which slats are particularly advantageously formed in a serpentine shape. Therefore, a particularly simple operation of the assembler using it is produced by a circular structure and a serpentine slat at the angle of humanized use. It is also advantageous to have a technically functionally pleasing appearance and a knob that is particularly advantageously integrated into the tool 157372.doc 201217117. The knob 14 does not protrude outwards and thus does not pose for example a risk of injury or the like. It is particularly advantageous for this to be that the receptacle is formed as a line and the geometry of the (four) is adapted to be incorporated into the flash. Other advantages, features, characteristics, and aspects of the present invention will be apparent from the following description. [Embodiment] The same reference numerals are used in the drawings for the same or similar components, and the repeated description is omitted for the sake of simplicity. Figure 1 shows that the toolbox of the present invention is in an open state. The toolbox has for this purpose a first housing part 2 and a second housing part 3. The housing portions #2, 3 have a side 4, two longitudinal sides 5 and a rear side 6, respectively. The two housing parts 2 , 3 are pivotally coupled to one another on the rear side on a pivot axis 7 . On the front side 4 of the first housing part 2, a knob is provided, which can be engaged in a positive-locking manner with the abutment section 9 of the second housing part. For this purpose, the abutment section 9 on the second housing part 3 has a stop projection 丨〇. Figure 2 shows a front view and a rear view of the knob 8 of the present invention. Here, the back view is shown in the figure, and the front view is displayed in the hole. The figure shows a rear view of the knob 8 with a rotating bump 12 centered on the rear side U of the knob 8. In addition, the stop means 13 shown here in the form of a bump are provided for engagement with a seat section of the housing part which is not described in detail. Similarly, a stop projection 14, which is combined with a restriction groove not shown in detail here, limits the rotational movement of the knob 8. Also set on the rear side u of the knob 8 are two stop tabs 157372.doc 201217117 15. The stop tongue 15 engages in a slot-like engagement on the housing parts 2, 3, which is not described in detail here, such that the knob 8 is rotatably held in a fixed position on the first housing part as a loose support. Figure 2b shows the front side 16 of the knob 8 of the present invention. The knob 8 has a serpentine slat 17 extending generally along the center of its front side 16. The knob 8 can be operated by the assembler's limbs through the slats 17. Figure 3 shows a perspective view of the toolbox of the present invention when the knob 8 is first assembled. The knob 8 is arranged in a gap 18 formed by the closed housing parts 2, 3. The knob is engaged into the rotary bump support 19 by a rotary bump not described in detail herein. A spring-elastic adjusting element 2 is provided around the rotary bump support 19 and the rotary bump 12, which is in the form of a helical spring. The spring-elastic adjusting element 20 has a continuation 21 on its two ends, which is a spring force transmitted between the first housing part 2 and the knob 8. Figure 4 shows a front view of the first housing part 2 and the second housing part, respectively. It can be seen in Fig. 4a that approximately 2/3 of the gap is formed on the first housing part 2, and a gap of 1/3 is formed on the second housing part 3 in Fig. 4b. Thus, by the mutual engagement of the two housing parts 2, 3 of the closed tool case of the invention, the entire gap 18 is formed for a knob not described here. The portion of the recess 8 on the first body member 2 has a rotating bump support 19, two slots 22 and a limiting slot 23 for engaging a stop tab not described in detail herein. 'The limiting groove is for engaging a stop bump not described in detail herein. In addition, the first housing part 2 has a bearing table... 157372.doc • 10· 201217117 A support for the spring-elastic adjusting element which is not described here on the housing side. The second housing part 3 shown in Fig. 4b has a seat section 9 in the form of a stop projection 10 in the section of the recess 18. A stop means for a knob, not described in detail here, is positively engaged in the stop projection. Therefore, the locking function between the two housing parts 2, 3 between the rotary bump support 19 and the stop projection 10 is obtained during free cutting, and the force is transmitted by a knob not described in detail herein.
