[0005] The invention relates to a tool case, in particular a hand tool case, with a base body having a side wall, a base body bottom and a receiving area for a tool, and with a lid which is provided to cover the receiving area of ​​the base body in a closed state.

[0006] At least one stiffening dome unit is proposed, designed to support at least one force perpendicular to the base of the base body. The term "tool case" is advantageously understood to include a hand tool case. A "stiffening dome unit" is understood to be, in particular, a unit designed to support a side wall when it absorbs forces perpendicular to a principal extension plane of a base body. Advantageously, the stiffening dome unit has at least two sections. Most advantageously, the tool case has at least three or four stiffening dome units. In particular, the stiffening dome unit has a spatial extent in at least two directions of extension that is at least twice the thickness of the side wall.Advantageously, the spatial extent is three times larger, and particularly advantageously five times larger, than the wall thickness of the side wall. Advantageously, the directions of extension are arranged perpendicular to each other. It is also advantageous for the directions of extension to be aligned parallel to a plane of the base. A "receiving area" is understood to be, in particular, an area bounded by the inner sides of the lid, the side walls of the lid and the base, and the base of the base when the lid is closed. Advantageously, the receiving area is designed to accommodate at least one tool, hand tool, and / or power tool, such as a drill, a hammer drill, a jigsaw, and / or other items that a person would consider useful, such as accessories, battery packs, chargers, materials, and / or tools.The term "base body" refers specifically to a part of the toolbox designed to hold the tool, at least when the toolbox is opened and / or during its intended use. In this case, the base body absorbs the tool's bearing forces. Advantageously, the base body surrounds the tool stored within it, or the holding area, on at least five sides when the lid is open. A "side wall" refers specifically to a part of the base body that defines a holding area perpendicular to a plane formed by the base body's bottom. Advantageously, the side wall defines the holding area on four sides.The term "base body bottom" shall be understood to mean, in particular, a partial surface of the base body that bounds the receiving area on at least one side and / or that runs approximately parallel to a plane formed by the lid. If none of the partial surfaces of the base body runs parallel to this plane, the largest partial surface of the base body shall be understood as the base body bottom. Advantageously, the base body bottom bounds the receiving area on a side of the receiving area facing away from the lid. The term "closed state" shall be understood to mean, in particular, a state in which the base body and the lid enclose the receiving area by at least 95%, and advantageously by 99%. Most advantageously, they enclose the receiving area completely. The term "lid" shall be understood to mean, in particular, a part of the tool case that is movable relative to the base body and / or that bounds the receiving area on at least one side.Preferably, the lid has a lid wall and also a side wall. The design of the tool case according to the invention advantageously increases the load-bearing capacity of the tool case under forces acting on the lid and the base body. This allows many tool cases or pallets of tool cases to be stacked advantageously without damage occurring to the tool cases.

[0007] In a further embodiment, it is proposed that the stiffening dome unit has at least one cross-sectional area whose smallest dimension through a center point of the cross-sectional area is at least twice the thickness of the side wall. "Wall thickness" is understood to mean, in particular, the thickness of the side wall perpendicular to a principal plane of extension on an inner surface of the side wall. Advantageously, the cross-sectional area is at least three times, and particularly advantageously at least five times, the thickness of the side wall. Preferably, the cross-sectional area is arranged parallel to the base of the body. "Smallest dimension" is understood to mean, in particular, a smallest diameter. The large cross-sectional area allows for a particularly high load-bearing capacity to be achieved structurally in a straightforward manner.

[0008] According to the invention, the stiffening dome unit has at least one cross-sectional area that is at least partially located within the receiving area. Alternatively, the cross-sectional area can also be located outside the receiving area, for example, on an outer surface of the side wall and / or integrated into a side wall and / or at another location that would be considered suitable by a person skilled in the art. By arranging the cross-sectional area of ​​the stiffening dome unit within the receiving area, the stiffening dome unit can be used to divide and organize the receiving area. Thus, the stiffening dome unit fulfills two functions: structuring and stabilizing the tool case.

[0009] Furthermore, at least one cover wall and at least one base body bottom wall are proposed, between which the stiffening dome unit forms a material connection when the cover is closed. A "base body bottom wall" is understood to be, in particular, a wall of the base body whose inner surface defines the receiving area along the base body bottom. A "cover wall" is understood to be, in particular, a wall of the cover that, when the cover is closed, is arranged parallel to a plane forming the base body bottom wall. A "material connection" is understood to be, in particular, a connection that, along at least one straight line from the base body bottom wall to the cover, which is arranged perpendicular to a principal extension plane of the base body bottom wall, comprises at least 95% material, advantageously 99% material.The force is transferred from the top wall via directly adjacent support surfaces of the stiffening dome unit directly to the base wall. This material connection allows for the simple and space-saving dissipation of particularly large forces.

[0010] According to the invention, the stiffening dome unit comprises at least one stiffening dome element arranged on the lid and at least one stiffening dome element arranged on the base body, both of which have corresponding support surfaces. A "stiffening dome element" is understood to be, in particular, a sub-region of the stiffening dome unit. Advantageously, the stiffening dome unit has at least two sub-regions. The term "corresponding support surfaces" is understood to be, in particular, surfaces where the stiffening dome elements of the lid and the base body touch or make contact when the lid is closed. Advantageously, the support surfaces are designed to transmit at least the force from one stiffening dome element to another stiffening dome element.By means of corresponding support surfaces, the stiffening dome unit can be divided into stiffening dome elements, thus enabling an advantageous arrangement of the stiffening dome unit. In particular, it can be prevented that the stiffening dome unit projects beyond the side wall of the base body in a direction perpendicular to a plane of the base body.

[0011] In an advantageous embodiment of the invention, it is proposed that the stiffening dome unit comprises at least one form element designed to align at least a portion of the stiffening dome unit when the lid is closed and / or when the lid is closed. "Aligning a portion of the stiffening dome unit" is understood to mean, in particular, that the form element positions and / or arranges that portion of the stiffening dome unit relative to something else. Advantageously, the form element aligns one of the stiffening dome elements. Particularly advantageously, the form element aligns one of the stiffening dome elements relative to other stiffening dome elements of the tool case. Preferably, the form element centers one of the support surfaces of the stiffening dome unit relative to another support surface of the stiffening dome unit. The phrase "a portion of the stiffening dome unit" is understood to refer specifically to one of the stiffening dome elements.The molded element enables the stiffening dome unit to withstand particularly high shear forces. Furthermore, the molded element ensures precise alignment of the stiffening dome elements when the lid is closed.

[0012] In a further embodiment, it is proposed that the stiffening dome unit has at least one support element designed to stabilize at least part of the stiffening dome unit, at least under load. Advantageously, the support element is designed as a support web. The term "stabilize" is understood to mean, in particular, that the support element counteracts any change in position of at least part of the stiffening dome unit relative to the base body and / or the cover. The support element allows the stiffening dome unit to transfer lateral forces to the base element and / or the cover in a structurally simple and stable manner.

[0013] Furthermore, at least one alignment unit is proposed, designed to align the stiffening dome unit relative to another stiffening dome unit. An "alignment unit" is understood to mean, in particular, a unit that facilitates the arrangement of the tool case, especially relative to another tool case, and / or, as required, at least counteracts any displacement of the tool case in a direction parallel to the base of the base relative to another tool case. Specifically, "align" is understood to mean positioning relative to something. Using the alignment unit, several tool cases can be stacked particularly easily in such a way that the stiffening dome units of the tool cases are advantageously aligned with each other in a stabilizing manner.

[0014] Furthermore, it is proposed that the alignment unit be arranged on an outer surface of the cover and / or on an outer surface of the base body. An "outer surface" is understood to mean, in particular, a side of a wall of the base body and / or the cover facing away from the receiving area. Advantageously, the base of the alignment unit should be arranged parallel to the base body and be at least half the cross-sectional area of ​​the stiffening dome unit. By arranging the alignment unit on an outer surface, its design can be simple and cost-effective.

[0015] Furthermore, it is proposed that the stiffening dome unit have at least a partially cylindrical basic shape. A "basic shape" is understood to refer in particular to a geometric sub-area of ​​the stiffening dome unit. Alternatively, the stiffening dome unit may have a different basic shape, other than a cylinder, which appears advantageous to a person skilled in the art. The advantageous cylindrical basic shape is particularly stable and space-saving.

[0016] In an advantageous embodiment of the invention, it is proposed that the stiffening dome unit at least partially encloses a cavity. Preferably, the stiffening dome unit, or the stiffening dome means, completely enclose the cavity when the lid is closed. Advantageously, the stiffening dome unit has a hollow cylindrical shape. The cavity advantageously allows for a reduced material requirement and thus a low weight of the tool case.

[0017] In a further embodiment, it is proposed that the stiffening dome unit be formed at least partially integrally with the side wall. The phrase "at least partially integrally" is intended to mean, in particular, that the stiffening dome unit has a partial section and the side wall has a partial section, wherein the two partial sections are formed in one piece and / or from a single casting and / or designed as a single component. This integral construction allows the stiffening dome unit to be advantageously stabilized by the side wall.

[0018] Furthermore, a system comprising a first and at least one second tool case is proposed, wherein the alignment unit is designed to align the stiffening dome unit of the first tool case relative to the stiffening dome unit of the second tool case. Preferably, the tool case has an alignment unit on a lid and an alignment unit on a base. Advantageously, the centers of the surfaces of the alignment units are arranged on a line perpendicular to the base. The alignment units allow the tool cases to be advantageously aligned relative to each other.

[0019] Furthermore, it is proposed that the alignment unit be designed to transfer a large portion of a force to the second toolbox via the stiffening dome unit of the first toolbox. Advantageously, the alignment unit transfers the large portion of a force to the stiffening dome unit or the alignment unit of the second toolbox. A "large portion of a force" is understood to mean at least 50%, or preferably 80%, of a force acting perpendicular to a plane of the base of the toolbox. Preferably, the stiffening dome unit(s) is designed to transfer a total force of at least 500 N, or preferably at least 750 N, without causing damage. By transferring a large portion of the force via the stiffening dome unit or the second toolbox, the alignment unit is designed to prevent damage to the toolbox.By transferring the force to the stiffening dome units, damage such as shiny spots, pressure marks, and / or deformations of the side walls, lid, and / or base body can be advantageously prevented, or shiny spots and pressure marks can be limited to the alignment unit. Advantageously, several tool cases transported on one pallet can thus be loaded with at least one additional pallet parallel to the force. The additional pallet may weigh less than 800 kg in total. The force resulting from the 800 kg load is preferably distributed across several tool cases in parallel. drawing

Description of the exemplary implementations

[0022] Fig. Figure 1 shows a toolbox 10a with a base 12a and a lid 20a. The base 12a has a side wall 14a, a base 16a, and a receiving area 18a for a hand-held power tool (not shown in detail). The base 16a is designed as a rectangular base wall 32a. The side wall 14a is arranged along an approximately rectangular outer edge of the base 16a. Furthermore, the side wall 14a extends along the outer edge of the base 16a on four sides of the receiving area 18a and, when the lid 20a is closed, perpendicular to the base 16a, in the direction of the lid 20a. The lid 20a is shown here in an open position.

[0023] The cover 20a is positioned above the base body 16a and has a rectangular cover wall 30a and a side wall 62a. When the cover 20a is closed, the cover wall 30a is parallel to the base body 16a. The side wall 62a extends from an outer edge of the cover wall 30a, perpendicular to the base body 16a, to the side wall 14a of the base body 16a. In a closed state, the cover 20a covers the receiving area 18a of the base body 12a.

[0024] The tool case 10a has a hinge 64a that connects the lid 20a and the base body 12a so that they can move about a hinge axis. The hinge 64a is designed as a rod hinge. It is located between two outer edges of the side walls 14a, 62a along the outer edges on one side of the tool case 10a and extends parallel to the base body 16a.

[0025] Furthermore, the tool case 10a has a handle 66a, which is located on a side of the tool case 10a facing away from the hinge 64a. The handle 66a is formed by a handle wall 68a and two openings 70a, 72a. One of the openings 70a is located in the lid wall 30a. The other opening 72a is located in the base 16a. The handle wall 68a connects the two openings 70a, 72a and is designed to be detachable for opening the tool case 10a. The handle wall 68a encloses a passage formed by the two openings 70a, 72a and is oriented perpendicular to the base 16a.

[0026] The lid 20a and the base body 12a are in contact along the outer edges of the side walls 14a, 62a when the lid 20a is closed. These outer edges are arranged along the side walls 14a, 62a of the lid 20a and the base body 12a, respectively, approximately on a plane between the lid wall 30a and the base body bottom wall 32a. The tool case 10a has coupling elements 74a for this purpose. The coupling elements 74a prevent the contact of the side walls 14a, 62a from being dislodged by forces 24a ( Fig. 2), which act on the lid 20a or the base body 12a, is released. For this purpose, the coupling elements 74a are designed as form elements. Furthermore, the lid 20a of the tool case 10a has stiffening elements 76a that stiffen the side wall 62a. The stiffening elements 76a are integrally formed with the side wall 62a of the lid 20a and are integrally formed with the side wall 62a. The stiffening elements 76a are oriented perpendicular to a principal extension plane of the lid wall 30a. In addition, the stiffening elements 76a, like the coupling elements 74a, prevent the contact of the side walls 14a, 62a from being caused by forces 24a ( Fig. 2), which act on the lid 20a or the base body 12a, releases.

[0027] In Fig. 1 is one of the stiffening elements 76a, shown by way of example with a reference numeral.

[0028] Tool case 10a has organizing elements 78a, which are mostly arranged in the receiving area 18a. The organizing elements 78a are designed as ribs. They are molded onto the lid wall 30a, the base 16a, and the side walls 14a and 62a. The organizing elements 78a prevent a tool or hand tool placed in tool case 10a from shifting during transport. Furthermore, the organizing elements 78a serve as an orientation aid, assisting a user (not shown) in arranging the tools in tool case 10a.

[0029] The tool case 10a has four stiffening dome units 22a. The stiffening dome units 22a support forces 24a perpendicular to the base body 16a. Such forces 24a occur, for example, when several tool cases 10a are stacked on top of each other on their base body walls 32a and their lid walls 30a. The tool case 10a can support forces 24a perpendicular to the base body 16a of at least 800 N without damage. Fig. For the sake of clarity, only one of the four stiffening dome units 22a has all parts or areas of the stiffening dome units 22a marked with reference symbols.

[0030] The four stiffening dome units 22a have a cylindrical base shape 56a. The base shape 56a is designed as a hollow cylinder. Thus, each stiffening dome unit 22a encloses a cylindrical cavity 58a, which is located in the center of the respective stiffening dome unit 22a and extends from the cover wall 30a to the base body bottom 16a.

[0031] The stiffening dome units 22a have circular cross-sectional areas 26a, the smallest dimensions of which, passing through a center point of the cross-sectional areas 26a, are four times the wall thickness 28a of the side walls 14a, 62a. The cross-sectional areas 26a therefore correspond to a circular area with a diameter four times the wall thickness 28a of the side wall 14a of the base body 12a. The cross-sectional areas 26a of the stiffening dome units 22a are distributed within the receiving area 18a, near corners 80a of the tool case 10a.

[0032] The stiffening dome units 22a each have two parts 42a, namely an upper and a lower stiffening dome element 34a, 36a. The upper stiffening dome element 34a is arranged on the cover 20a and is formed integrally with the cover 20a. The lower stiffening dome element 36a is arranged on the base body 12a or the base body bottom wall 32a and is formed integrally with the base body 12a or the base body bottom wall 32a. When the cover 20a is closed, two support surfaces 38a of each stiffening dome unit 22a correspond by touching each other. Thus, when the cover 20a is closed, the stiffening dome units 22a form a material connection between the cover wall 30a and the base body bottom wall 32a.

[0033] Furthermore, the stiffening dome units 22a each have four shaped elements 40a. The shaped elements 40a are integrally formed with a basic shape of the stiffening dome units 22a. When the lid 20a is closed, and when the lid 20a is closed, the shaped elements 40a align the upper stiffening dome center 34a and the lower stiffening dome center 36a with each other.

[0034] Furthermore, the stiffening dome units 22a each have two or three support elements 44a. The support elements 44a stabilize the stiffening dome means 34a, 36a of the stiffening dome units 22a under load by counteracting lateral buckling of the stiffening dome means 34a, 36a.

[0035] Fig. Figure 2 shows a section perpendicular to a main extension direction of the hinge 64a through one of the stiffening dome units 22a of the tool case 10a. Fig. 1. Viewed from a side 82a opposite the hinge center. A system 84a consisting of an upper tool case 10a and a lower tool case 10a' is shown. For clarity, some reference symbols are shown only on the upper tool case 10a or only on the lower tool case 10a'. These reference symbols can also be applied analogously to the other tool case 10a, 10a'. In Fig. Figure 2 shows that the tool cases 10a, 10a' each have an upper alignment unit 46a and a lower alignment unit 48a. Not shown is that each of the four stiffening dome units 22a of the two tool cases 10a, 10a' is assigned two such alignment units 46a, 48a.

[0036] The upper alignment units 46a are designed as circular recesses. The lower alignment units 48a are designed as circular protrusions. The circular protrusions and recesses extend parallel to the base body 16a. The protrusions are slightly higher – in this embodiment by 0.3 mm – than the recesses in a direction perpendicular to the base body 16a. The alignment units 46a, 48a, and the basic shape of the stiffening dome unit 22a are arranged along a common central axis that is oriented perpendicular to a plane of the base body 16a.

[0037] The upper alignment units 46a are arranged on the upper outer sides 52a of the cover wall 30a. The lower alignment units 48a are arranged on the lower outer sides 54a of the base body floor 16a.

[0038] The lower alignment units 48a of the upper tool case 10a engage with the upper alignment units 46a of the lower tool case 10a'. This aligns the stiffening dome units 22a of the upper tool case 10a and the upper alignment units 46a of the lower tool case 10a' relative to the stiffening dome units 22a' of the lower tool case 10a'.

[0039] The different elevations and depressions of the alignment units 46a and 48a space the tool cases 10a and 10a' apart. Thus, the alignment units 46a and 48a form the only connection points between the upper tool case 10a and the lower tool case 10a'. As a result, forces 24a acting on the lids 20a or the base bodies 12a of the tool cases 10a and 10' are largely transferred from the upper tool case 10a to the lower tool case 10a' via the stiffening dome units 22a. Therefore, under the intended load, any shiny spots and wear occur exclusively on the alignment units 46a and 48a. Only when particularly large forces 24a are applied, which would overload the stiffening dome units 22a, does the base body 16a of the upper tool case 10a come to rest on a lid wall 30a of the lower tool case 10a' due to a slight deformation of the stiffening dome units 22a.In this case, the side walls 14a, 62a of the tool case 10a, 10a' support the stiffening dome units 22a in supporting the forces 24a. The particularly large forces 24a amount to at least 750 N.

[0040] In the Fig. Figures 3 to 7 show three further embodiments of the invention. To distinguish the embodiments, the letter 'a' in the reference numerals of the embodiment is used in the Fig. 1 and Fig. 2 by the letters b to d in the reference numerals of the exemplary embodiments in the Fig. 3 to 7 are replaced. The following descriptions are essentially limited to the differences between the exemplary embodiments, whereby with regard to components, features and functions that remain the same, reference is made to the description of the other exemplary embodiments, in particular in the Fig. 1 and Fig. 2, can be referred to.

[0041] Fig. Figure 3 shows a detailed perspective view of a second embodiment of a toolbox 10b with stiffening dome units 22b. The detailed view shows a section of a base body 12b of the toolbox 10b, which has a side wall 14b, a base body bottom 16b, and a receiving area 18b for a hand tool (not shown in detail). A lid 20b of the toolbox 10b is shown in an open position. One of four stiffening dome units 22b of the toolbox 10b is shown. The stiffening dome units 22b have a U-shaped base 56b.

[0042] The stiffening dome units 22b each have eight shaped elements 40b. The shaped elements 40b are integrally formed with a U-shaped base 56b of the stiffening dome units 22b. Furthermore, the shaped elements 40b extend perpendicularly to a principal extension plane of the base body 16b. When the lid 20b is closed, and when the lid 20b is closed, the shaped elements 40b align one upper stiffening dome element 34b and one lower stiffening dome element 36b of the stiffening dome units 22b with each other. In this embodiment, the shaped elements 40b also serve to stiffen the stiffening dome units 22b. The shaped elements 40b are integrally formed with support elements 44b. Fig. 1 only two of the support elements 44b are provided with a reference symbol as examples.

[0043] Fig. Figure 4 shows a section through a third embodiment of a tool case 10c. The section runs parallel to a base 16c of a base body 12c of the tool case 10c. One of four stiffening dome units 22c of the tool case 10c is shown. The stiffening dome units 22c are integrated into side walls 14c, 62c of the base body 12c and the lid 20c. The stiffening dome units 22c are formed integrally with the side walls 14c, 62c. Cross-sectional surfaces 26c of the stiffening dome units 22c are arranged offset from the outer surfaces 86c of the side walls 14c, 62c in the direction of a receiving area 18c of the tool case 10c. This creates bulges in the side walls 14c, 62c extending into the receiving area 18c.

[0044] Fig. Figure 5 shows a cross-section VV through tool case 10c. Fig. 4. The section runs perpendicular to the base of the basic body 16c. A lid 20c of the toolbox 10c is shown in a closed state. As in the Fig. 4 and Fig. As can be seen in Figure 5, cavities 58c of the stiffening dome units 22c have openings 88c on an outer surface 86c of the side walls 14c, 62c. These openings 88c can serve as additional handles for the tool case 10c.

[0045] Fig. Figure 6 shows a section through a fourth embodiment of a toolbox 10d. The section runs as shown in Fig. 4 also parallel to a base body 16d of a base body 12d of the tool case 10d. One of four stiffening dome units 22d of the tool case 10d is shown. The stiffening dome units 22d are integrated into side walls 14d, 62d of the base body 12d and the lid 20d. The stiffening dome units 22d are formed integrally with the side walls 14d, 62d. Cross-sectional surfaces 26d of the stiffening dome units 22d lie centrally on an imaginary mid-surface 90d of the side walls 14d, 62d. The mid-surface 90d runs parallel to the side walls 14d, 62d at a midpoint of the side walls 14d, 62d.

[0046] Fig. Figure 7 shows a section VI-VI through the toolbox 10d from Fig. 6. The section runs perpendicular to the base of the base body 16d. A lid 20d of the toolbox 10d is shown in a closed state. As in the Fig. 6 and Fig.As can be seen in Figure 7, the stiffening dome units 22d have cavities 58d which are almost completely closed when the lid 20d is closed.
