Description

[0001] The invention relates to a tool case, in particular a stackable tool case.

[0002] Commercially available stackable tool cases essentially have the following designs: 1. The Taiwanese utility model TW M428033 discloses a tool case which has a first housing part and a second housing part, wherein a plurality of locking pieces are arranged on the outer housing surface of the first housing part and a plurality of support parts, each corresponding to the locking pieces, are arranged on the outer housing surface of the second housing part, wherein when the tool cases are lying flat and stacked on top of one another, the support parts of the second housing part are supported on the respective corresponding locking pieces such that the second housing part remains stable on the first housing part, wherein this type of arrangement only enables a stable stacking of the tool cases and does not enable the tool cases to be transported at once; 2. Taiwanese utility model TW M427245 discloses a tool case comprising two housing parts, on each of which positioning discs are arranged, each with a gap to the respective surface of the housing parts. To assemble two tool cases, the housing part is moved so that the positioning discs are positioned in the gaps of the other housing part and thus fastened. The positioning discs are usually screwed to the housing part by means of bolts. When lifting and transporting a unit comprising several of these tool cases, it may happen that the positioning discs break or the bolts come loose due to the heavy weight of the lower tool case, so that tool cases of this type are not suitable for being lifted and transported all at once. 3. Taiwanese utility model TW M500665 discloses a tool case comprising a main body and at least two connecting elements pivotally connected to the main body. In order to stack two tool cases, the connecting elements of the upper tool case are inverted and then snapped into the recesses of the lower main body, so that the vertically stacked main bodies remain stable and can thus be easily stored and transported. However, the structure of the pivot connection by means of which the connecting elements are pivotally connected to one main body is easily subjected to an external force striking or pulling on this structure, thereby damaging this structure. It is also possible that, when two main bodies are connected, the locking of one main body to the other main body is released under the influence of an external force.The connecting elements must be pressed into the recesses with force to engage them, and pulled out of the recesses with force to release them. Over time, the connecting elements wear out and break due to such use, thus losing their locking function.

[0009] As from Fig. 1 and Fig. 2, the stackable tool case according to the invention comprises, according to a preferred embodiment, a housing 10 and a rotatable closure 20.

[0010] The housing 10 is substantially rectangular and includes a first surface 11, a second surface 12, a plurality of adjacent surfaces, two first recesses 14, two second recesses 15, two first raised blocks 16, two second raised blocks 17, and two detent bodies 18.

[0011] The first and second surfaces 11, 12 are located on opposite sides of the housing 10, with one of the adjacent surfaces being defined as the first adjacent surface 13. The housing 10 preferably comprises two housing parts 10A, 10B, which are pivotally connected to one another on the side facing away from the first adjacent surface 13, such that they form the housing 10 when joined together. The first and second surfaces 11, 12 are each located on the two housing parts 10A, 10B, with the adjacent side walls of the two joined housing parts 10A, 10B forming the adjacent surfaces of the housing 10, with connecting disks being arranged on the side of the first adjacent surfaces 13 of the two housing parts 10A, 10B.

[0012] As in Fig. 1 and Fig. 5, the two first recesses 14 are recessed on the first surface 11 of the housing 10 and are located on two opposite sides of the first surface 11, facing away from the first adjacent surface 13. The respective first recess 14 comprises a bottom wall 141 and a plurality of side walls, wherein a first oblique angle 142, which is an acute angle, is formed between the bottom wall 141 and the side wall facing away from the first adjacent surface 13. The two second recesses 15 are recessed on the first surface 11 of the housing 10 and are located on two opposite sides of the first surface 11.

[0013] As in Fig. 2 and Fig. 5, the two first raised blocks 16 are formed in accordance with the position and shape of the two first recesses 14 and are thus arranged on the second surface 12 of the housing 10, wherein the respective first raised block 16 comprises a top wall 161 and a plurality of side walls, wherein a second oblique angle 162 is formed between the top wall 161 and the side wall facing away from the first adjacent surface 13, which second oblique angle is an acute angle and matches the first oblique angle 142 of the corresponding first recess 14. The two second raised blocks 17 are formed in accordance with the position and shape of the two second recesses 15 and are thus arranged on the second surface 12 of the housing 10.

[0014] As in Fig. 2 and Fig. 3, two locking bodies 18 are arranged at a distance from one another in the direction extending from the first surface 11 to the second surface 12 on the first adjacent surface 13 of the housing 10, wherein one side of the respective locking body 18, which faces the other locking body 18, is designed as a circular arc-shaped surface.

[0015] As in Fig. 1, Fig. 3 and Fig. 4, the rotatable closure 20 is rotatably connected to the first adjacent surface 13 of the housing 10. The rotatable closure 20 comprises a connecting part 21 and two locking recesses 22, wherein the connecting part 21 is arranged in the center of the rotatable closure 20 and is rotatably connected to the first adjacent surface 13 of the housing 10, wherein the connecting part 21 is located on the side of one locking body 18, which side faces away from the other locking body 18. In the preferred embodiment, a round hole is arranged on the first adjacent surface 13 of the housing 10. The connecting part 21 of the rotatable closure 20 is cylindrical and extends from the rotatable closure 20 to one side of the first adjacent surface 13 of the housing 10. Engagement parts 211 are arranged on the connecting part 21 so as to project radially outward and can thus engage with the housing 10.A notch 212 is arranged on the connecting part 21, extending along the direction of the connecting part 21. Such a structure achieves the advantage of making the connecting part 21 more flexible and thus easier to attach to the housing 10. However, the connecting part 21 of the rotary shutter 20 is not limited to the above embodiment. Alternatively, the connecting part 21 of the rotary shutter 20 and the housing 10 can be connected to each other by means of a rotary connection arrangement with mating concave and convex structures. It is also conceivable that the connecting part 21 of the rotary shutter 20 and the housing 10 are connected to each other by means of a rotary shaft element.

[0016] The two locking recesses 22 are recessed on the first adjacent surface 13 of the rotatable closure 20 and are each located on two opposite sides of the connecting part 21, wherein one side of the respective locking recess 22, which faces away from the other locking recess 22, is designed as a circular arc-shaped surface that mates with the circular arc-shaped surface of the respective locking body 18 of the housing 10, wherein the distance from the circular arc-shaped surface of the respective locking recess 22 to the axis of the connecting part 21 is substantially equal to the distance from the circular arc-shaped surface of the locking body 18 of the housing 10 facing the rotatable closure 20 to the connecting part 21. The rotatable closure 20 has a connecting position and an initial position.When the rotatable closure 20 is in the connecting position, the locking body 18 of the housing 10 facing the rotatable closure 20 is enclosed by one locking recess 22 of the rotatable closure 20.

When the rotatable closure 20 is in the connecting position, the two housing parts 10A, 10B can be connected to one another by means of the rotatable closure 20.

[0017] For stacking two tool cases according to the invention on top of each other, as in Fig. 5 and Fig. 6, two first raised blocks 16 of the housing 10 of a tool case shown on the left side of the drawing are inserted into two first recesses 14 of the housing 10 of a tool case shown on the right side of the drawing such that the first raised blocks 16 of the left housing 10 are each received in the two first recesses 14 of the right housing 10 and thus abut against the first recesses 14. Further, the second bevel angles 162 of the first raised blocks 16 of the left housing 10 are brought into engagement with the first bevel angles 142 of the first recesses 14 of the right housing 10; at the same time, the second raised blocks 17 of the left housing 10 are brought into contact with the second recesses 15 of the right housing 10. Thus, the two tool cases are stacked on top of one another. As shown in Fig. 7 and Fig. 8, the rotatable closure 20 facing the contact surfaces of the two housings 10 is rotated into the connecting position such that the two locking recesses 22 of the rotatable closure 20 each enclose a locking body 18 of the two housings 10 and thus connect the two housings 10 to one another. Preferably, a groove 181 is arranged on each of the arcuate surfaces of the locking bodies 18 of the respective housing 10, and a projection 221 is arranged on each of the arcuate surfaces of the locking recesses 22 of the rotatable closure 20, which projection mates with the respective groove 181 of the locking bodies 18. The rotatable closure 20 and the locking bodies 18 thus engage with one another in the connecting position.

[0018] As from Fig. 1 and Fig. As can be seen in Figure 9, a carrying handle receptacle 19 is preferably arranged in the center of the first surface 11 or the second surface 12 of the housing 10, and a carrying handle 30 is rotatably mounted in the carrying handle receptacle 19 of the housing 10. Once two housings 10 are connected to each other, the user can carry and transport the two housings 10 together using the carrying handle 30.

[0019] Further is from Fig. 1 and Fig. 3 that the housing 10 can also be designed such that a U-shaped slot 101 is arranged on the side wall of one housing part 10B, the opening of which faces the other housing part 10A, with a stopper 102 protruding from the other housing part 10A, the stopper 102 being formed in correspondence with the opening of the slot 101. Thus, with the housing 10 open, the user can insert business cards into the slot 101.

[0020] The above technical measures achieve the following advantages in the stackable tool case according to the invention: 1. the tool case according to the invention is simple in design and easy to manufacture and assemble; 2. the stacking structure of tool cases according to the invention makes it possible for several tool cases to be stably stacked on top of each other, connected to each other and carried and transported at the same time; 3. According to the invention, the connection of two tool cases can be carried out easily, and a stable connection of two housings 10 can be achieved; and 4. It is possible to design the rotatable closure 20 such that the connecting part 21 of the rotatable closure 20 has a larger-diameter rotation axis, so that a more stable rotatable connection of the rotatable closure 20 to the housing 10 is achieved by the interaction of the larger-diameter rotation axis with an axle hole on the housing 10; moreover, the locking recesses 22 of the rotatable closure 20 advantageously enclose the locking bodies 18 of two housings 10 in such a way that this construction does not wear quickly and easily and thus has a longer service life.
