DETAILED DESCRIPTION OF THE INVENTION

(13) FIGS. 1 to 5 show a first embodiment of a transport and storage container 10 in different views, wherein in particular an inner container of the transport and storage container 10 is not depicted in more detail here, such that only an understructure 11 of the transport and storage container 10 is illustrated. The understructure 11 is substantially realized from an outer jacket 12, a bottom 13 as well as corner feet 14 and central feet 15 arranged between the corner feet 14 and from a bottom cross member 16 situated between the central feet 15. In detail, the corner feet 14 and the central feet 15 are arranged on skids 17 or 18. The bottom 13, the corner feet 14, the central feet 15, the bottom cross member 16 as well as the skids 17, 18 together realize a pallet 19. The outer jacket 12 arranged on the pallet 19 is realized from interlaced, horizontal and vertical grid bars 20, 21 made of metal, wherein in particular a lower grid bar 20 resting on the pallet 19, of the outer jacket 12, is embodied as a pipe 22, which is coupled to the corner feet 14 via attachment points 23 and to the central feet 15 via attachment points 24.

(14) A combined view of FIGS. 2 and 4 shows an attachment point 24 with a central foot 15, wherein the outer jacket 12 or the pipe 22 is not illustrated in the sectional view illustrated in FIG. 4. The bottom cross member 16 is formed from a profiled body 25 made of metal, and is arranged on an upper side 26 of the central foot 15. In addition, the bottom 13 has been placed onto the bottom cross member 16 or on the profiled body 25 above the bottom cross member 16 in an edge region 27 of the central foot 15. A bracket 28 is likewise arranged in the edge region 27, wherein the bracket 28 has an upper leg 29 and a lower leg 30. In the upper leg 29, a clearance opening 31 is realized and in the lower leg 30, a clearance opening 32 is realized. In the region of the clearance opening 32, a nose 33 is in addition realized at the lower leg 30. The lower leg 30 has been slid into a gap 34 between the upper side 26 of the central foot 15 and a lower side 35 of the profiled body 25, wherein the nose 33 engages with a clearance opening 36 of the profiled body 25. In this context, a land 37 of the bracket 28 coupling the legs 29 and 30 rests against an outer rim 38 of the bottom 13. The upper leg 29 reaches over the pipe 22 not illustrated in FIG. 4, of the outer jacket 12. In addition, a clearance opening 39 is likewise disposed in the bottom 13, wherein a screw 40 has been screwed into the central foot 15 through the clearance opening 31, 39, 32 and 36. In this context, the inside diameters 41 to 44 of the clearance opening 31, 32, 36 or 39 are dimensioned to be so large that a sufficiently large play relative to an outside diameter 45 of the screw 40 is realized, which prevents a touch with the screw 40 in the region of the inside diameters 41 to 44. The same is true for the clearance opening 36 not illustrated in a detailed fashion here, in the profiled body 25.

(15) An impact force now effected as a consequence of a crash of the transport and storage container 10 onto an outer rim 46 of the central foot 15 again leads to a deformation or shift of the inner container not illustrated here within the outer jacket 12, such that the outer jacket 12 for its part exerts a tensile force in the direction of a longitudinal axis 47 of the screw 40 onto the same. In this context, the tensile force directly acts on a screw coupling 48 of the screw 40 with the central foot 15. Since the pipe 22 is arranged between a screw head 49 or below the lower leg 29 and the central foot 15, the tensile force emanating from the pipe 22 acts on the bracket 28, such that a part of the tensile force can be transferred via the bracket 28 since the bracket 28 reaches under the profiled body 25 with the lower leg 30. The tensile force acting on the screw coupling 48 is consequently reduced by the tensile force transferred via the bracket 28, which reduces the risk of the screw 40 coming off the central foot 15. The tensile force transferred via the bracket 28 can also be transmitted into the profiled body 25 via the nose 33 at the lower leg 30 of the bracket 28. Moreover, the upper leg 29 serves as a bearing face 50 for the screw head 49, such that the use of a washer might be spared here.

(16) A combined view of FIGS. 6 and 7 shows a sectional view of an understructure 51 of a transport and storage container not illustrated in more detail here, in the region of a central foot 52. The fundamental construction of the transport and storage container and of the understructure 51 corresponds to the transport and storage container shown in FIGS. 1 to 5, apart from the differences described below. An outer jacket 53 of the understructure 51 rests on a circumferential bearing face 55 of a bottom 56 of the understructure 51 with a pipe 54. The bottom 56 for its part rests on an edge region 57 of the central foot 52 together with a one-piece profiled body 58, which embodies a bottom cross member 59. The bottom cross member 59 or the profiled body 58 couples the central foot 52 to an opposing central foot not illustrated in more detail here. In addition, a screw 60 is envisaged, which has been driven into an upper side 61 of the central foot 52 made of plastic material, in this way realizing a screw coupling 62. The screw 60 thus couples the outer jacket 53 to the bottom 56, the profiled body 58 or to the bottom cross member 59 and the central foot via pipe 54, whereby an attachment configuration 63 is realized in an attachment point 64 at the central foot 52.

(17) In addition, in the frame of the attachment configuration 63, a bracket 65 is envisaged, which reaches around the bottom cross member 59 or around the profiled body 58 at a lower side 66 and around the outer jacket 53 or the pipe 54. In an upper leg 67, a clearance opening 68 having a hollow 69 is realized, wherein a lower leg 70, in an unmounted state of the bracket 65, initially does not have any clearance opening whatsoever. The screw 60 has been guided through the clearance opening 68 in the bracket 65, through a clearance opening 71 in the pipe 54, a clearance opening 72 in the bottom 56, a clearance opening 73 in the profiled body 58 and a clearance opening 74, in the lower leg 70 of the bracket 65, realized upon driving in the screw 60. A tensile force effected by the loading case described above, of a crash of the transport and storage container, acting in the direction of a longitudinal axis 75 of the screw 60, is consequently transmitted into the central foot 53 via the screw 60 in this way, wherein a part of the tensile force is equally transmitted into the profiled body 58 or the bottom cross member 59 via the bracket 65, as a consequence of the form-fitting arrangement of the bracket or of the lower leg 70 below the profiled body 58, into the same. The screw coupling 62 with the central foot 52 is thus relieved by the amount of this part of the tensile force.

(18) Complementarily, a second screw 76 is envisaged, with the aid of which the profiled body 58 is coupled to the central foot 52 by screwing them together. The screw 76, the profiled body 58 and the central foot 52 thus realize a further attachment configuration 77, which serves to safely arrange the central foot 52 at the profiled body 58.

(19) A combined view of FIGS. 8 to 11 shows a sectional view of an understructure 78 of a transport and storage container not illustrated in more detail, in the region of a central foot 79. The construction of the transport and storage container and of the understructure 78 corresponds to the construction of the transport and storage container shown in FIGS. 6 to 7, apart from the differences described below. A bracket 80 reaches around a pipe 81 of an outer jacket 82, around a bottom 95 as well as around a profiled body 83 of a bottom cross member 84. A screw 85 penetrates the bracket 80, the pipe 81, the bottom 95, and the profiled body 83 and has been screwed into the central foot 79. The bracket 80 has an upper leg 86 and a lower leg 87, which are coupled via a land 88. One end 89 of the upper leg 86 is embodied so as to be angled, such that the bracket 80 can easily be slid onto the pipe 81. In addition, a clearance opening 90 having a hollow 91 for guiding the screw 85 is realized in the upper leg 86. A clearance opening 92 in the shape of an elongated hole having a hollow 93 like this is realized in the lower leg 87. The clearance opening 92 in the shape of an elongated hole allows for selectively arranging the screw 85 in the frame of the clearance opening 92 in such a manner that a longitudinal axis 94 of the screw 85 penetrates both clearance openings 90, 92. Clearance opening 92 is embodied such that the screw 85 deforms the clearance opening 92 upon being screwed into the same.
