Description

Pallet-type base for transport and storage containers for liquids

The invention relates to a pallet-like base, in particular for transport and storage containers for liquids, which are equipped with an inner container made of plastic, with a closable filler neck and a discharge nozzle for connecting a removal fitting, wherein the base frame an outer shell of a metal mesh or sheet, and a Floor for supporting the inner container, corner feet and disposed between the Eckfüßen middle feet and a floor cross member, wherein at least two middle feet at least the outer shell and the floor cross member are fixed, wherein the respective metatarsus, the outer shell and the floor cross member are positively connected by a screw. Furthermore, the invention relates to a

Transport and storage container with such a base.

Underframes of the type mentioned form a, for example, with suitable Hubstapeleinrichtungen manageable platform for storage and transport of plastic inner container formed. The outer jacket serves to protect the relatively vulnerable inner container from damage. The pallet-like subframe So ll ll therefore absorb particular shock loads that can act on the inner container, for example, in a collision of the transport and storage container on a floor. In particular, with an oblique impact of the transport and storage container on the ground or a substrate, it may come info lge the inertia of a flowable medium located in the inner container to deformation or slipping of the inner container on the bottom of the base. Info lge the outer sheath can be deformed in the region of the bottom of the base frame so that a protective cover formed by the outer shell and bottom of the base frame of the inner container in this area ruptures and the inner container is damaged. For transport and storage containers, which are intended for the transport of dangerous goods, therefore, appropriate, standardized drop tests are provided, although it is desirable to secure transport and storage containers in general against such damage.

In order to produce the bases for transport and storage containers as stable as possible at a reasonable cost of materials and low cost, it is known to bolt the outer shell directly with the interposition of the soil with the feet. The bottom and the feet of the undercarriage form a pallet, wherein the feet on an underside can also be interconnected by runners or a frame. Since the bottom serves to support the inner container, a bottom cross member is regularly provided below the bottom, which is arranged between two middle feet and connects them together. The bottom cross member also serves to stabilize the undercarriage in the event of an impact of the transport and storage container along a Fußrahmenseite on a substrate.

In the known transport and storage containers or bases of the outer shell or a lower surface of the outer shell is connected to the bottom, the floor cross member and the middle feet by means of screws. To make the base as simple and as possible To make inexpensive, the screw is passed through sufficiently large through holes in the peripheral edge, the bottom and the floor cross member and screwed only in the metatarsus. In the above-mentioned impact of the transport and storage container along a Fußrahmenseite it may now be a result of a considerable

Tensile stress of the screw to a tearing of the screw or to a tearing of the thread S screw from the metatarsal, whereupon the lower peripheral edge of the outer shell is separated from the bottom of the underframe so that the inner container can be deformed or damaged in this area. A pulling force acting on the screw from the peripheral edge of the outer sheath acts directly on the connection between the screw and the metatarsus, since a force flow alone, starting from the peripheral edge through the screw, passes to the metatarsus. In particular, if lightweight and inexpensive materials such as plastic or wood are to be used for the metatarsus, therefore, the screw and metatarsal screw connection has proven to be a weak point in case tests. In addition, the screw can be incorrectly positioned or "over-tightened" during assembly Depending on the storage location, even high temperatures can weaken a screw connection with, for example, plastic.

It is essential in such a mounting configuration that, to facilitate a relative positioning of the components in a mounting sufficiently large through holes are provided in the peripheral edge, in the bottom and in the floor cross so that they can be easily aligned relative to each other and the screw easily inserted through the through holes and can be screwed to the metatarsus. In particular, it is also advantageous if the passage openings are so generously dimensioned that a comparatively large clearance is formed between the aforementioned components and the screw. The present invention is therefore based on the object, a pallet-like base for a transport and storage container for liquids and a transport and storage container with a

To propose subframe, which ensures one or the increased security and yet easy and inexpensive to produce.

To solve this problem, the undercarriage according to the invention has the features of claim 1 and the transport and storage container according to the invention the features of claim 16.

In the undercarriage according to the invention, in particular for transport and storage containers for liquids, which are equipped with an inner container made of plastic, with a closable filler neck and an emptying nozzle for connecting a removal fitting, the base frame has an outer shell of a metal grid or sheet, and a bottom to Supporting the inner container, corner feet and arranged between the Eckfüßen middle feet and a floor cross member, wherein at least two middle feet at least the outer shell and the floor cross member are attached, wherein at least the respective metatarsus, the outer shell and the floor cross member by means of a screw in a mounting configuration with each other positively connected are, wherein a clamp is provided which engages around the bottom cross-piece and a peripheral edge of the outer shell, wherein the screw passes through legs of the clip.

Characterized in that the clip engages around the peripheral edge of the outer shell and the floor cross member, a tensile force caused by the peripheral edge on the screw can be at least partially derived on the bracket and introduced into the floor traverse. A screw of the screw and metatarsus can therefore be advantageously relieved. A risk of breakage or tearing of the screw or tearing of the screw from the metatarsus can thus be effectively reduced by the use and arrangement of the clip. Next are the cost of a clamp and its mounting on the Underframe due to the simple design and handling very low. Depending on the design of the undercarriage, this can in each case have a clamp at several attachment points.

Advantageously, the clip may be U-shaped or V-shaped and have two opposite legs. The clip may then be a U-shaped or V-shaped curved sheet metal strip. The clip may be adapted to a shape of the peripheral edge, the bottom cross-piece or the screw. For example, the clip may also be formed so that the clip locks with the bottom cross member and / or the peripheral edge during assembly of the clip.

As a result, an upper leg can be arranged above the peripheral edge and a lower leg between the middle foot and the floor crosspiece. When a gap is formed between the midfoot and the floor crossbeam, the lower leg can be easily inserted between the midfoot and the floor crossbeam in the gap. It can also be provided that on the upper leg a Börde- ment or an end of the upper leg is formed angled from the upper leg, such that formed on the upper leg a surface in the manner of a guide for centering the clip in an assembly thereof is. An assembly of the clip is thereby considerably simplified.

The clip may have a passage opening in at least the upper leg. Then, the screw can be easily inserted when mounted in the upper leg or in the passage opening formed therein. If it is, for example, a self-tapping sheet metal screw or another suitable screw, can be dispensed with the formation of a through hole in the lower leg, since then the screw can be easily screwed into the lower leg. Nevertheless, it is possible to provide a passage opening for the screw already in the lower leg. In the lower leg can also be formed a thread into which the screw engages, wherein the thread can then be formed by means of the screw. For example, in the lower leg a passage opening in the manner of a bore or a slot may be provided, into which the screw can be screwed. It can be provided that an inner diameter of the passage opening is smaller than an outer diameter of the screw, so that the screw when screwing the thread in the lower leg is formed. Again, a mounting of the screw is simplified because it can be easily aligned by means of the passage opening in the lower leg in a designated mounting position.

It when the passage opening is formed in the lower leg with a recess is particularly advantageous. A recess or a recess or bead allows easier insertion of the screw in the through hole such that the screw is guided to Durchgangsö opening. Furthermore, the region of the passage opening or screw connection with the lower limb can be stabilized by the depression or conical depression, so that the screw is torn out of the lower one

Thigh is difficult. The recess may have an opening angle of 90 °.

On the lower leg, a nose can be formed, wherein the nose can engage in a through hole of the floor cross member. The clip or the lower leg can then be inserted into a gap between the bottom cross member and the middle foot during assembly, wherein the nose can then engage in the passage opening of the floor cross member. So the clip can not be easily removed. In addition, the clip is then already secured in a, intended for assembly position. If a passage opening is formed on the lower leg of the clip, the nose can be located directly at one edge of the passage. be formed opening. It can further be provided that the nose has a wedge-shaped bevel, which facilitates insertion of the lower leg in the gap between the floor crossmember and the metatarsus.

Accordingly, the screw can be so firmly connected to the floor cross member that a force flow, which as a result of acting on the outer sheath tensile force, introduced from the outer sheath into the screw and / or the clip and by the screw and / or the clamp on the floor crossmember can be derived. The screw can thus be firmly connected directly to the ground crossmember. Next, the screw is firmly connected to the j eweiligen metatarsus, so that caused by the outer shell, for example, as a result of a crash of the transport and storage container within the screw and the clamp tensile force can be derived in the bottom crossbeam and the metatarsus. A screw of the screw and metatarsus is less stressed, resulting in increased stability or

Safety of the base leads without the need for other components in addition to the clip. A risk of corrosion does not exist in a screw connection of screw and floor cross member, since the screw with the floor cross member is then firmly connected or screwed so that a corrosion protection layer of a surface are not destroyed by a relative movement of the components or not

Abrasion can take place.

In a preferred embodiment, the metatarsus, the outer shell, the bottom, the bottom cross member and the bracket can be positively connected by means of the screw. Then, the fastening configuration formed in this way also includes the bottom of the underframe, which does not necessarily have to be directly connected to it in the region of the middle feet. Furthermore, the screw can then pass through passage openings formed in the outer casing, the bottom and the clamp. The passage openings may preferably be formed so that a sufficiently large clearance between inner can th of the through holes and the screw remains. The passage openings in the outer jacket can then be formed in the peripheral edge of the outer jacket. If the outer jacket is formed, for example, of intersecting, horizontal and vertical bars of metal, the through openings can in each case be formed in a lower horizontal tube, which then forms the peripheral edge.

The bracket and the floor cross member may preferably be formed of metal, wherein the floor may be formed of metal or plastic material. It can also be provided integrally to form the floor cross member, for example as a profile element or a manufactured by forming metal sheet component. The floor can also be made particularly cost-effective and stable from a deep-drawn sheet metal or alternatively from a synthetic material.

The screw connection of the screw and floor cross member can be formed particularly easily if a passage opening for engagement of the screw is formed in the floor cross member. This can then also be ensured that the screw is always screwed at an installation of the undercarriage at the designated location on the floor cross member in this. Further, an inner diameter of the through hole may be smaller than an outer diameter of the screw. Thus, it can then be ensured that a thread of the screw actually engages in the region of the passage opening with the material of the floor cross member.

A pulling force can thus, as already stated above, not be completely initiated by the screw alone in the metatarsus, but rather be absorbed to a not inconsiderable extent by the ground crosspiece via the clamp. The screw screwed into the metatarsus or the screw connection formed in this way is then subjected to less stress, so that, in particular in the case of middle feet made of plastic. material or wood, a tearing of the screw from the metatarsus can be avoided.

To make the lower frame even safer or more stable, the bottom cross-piece with a further screw form-fitting with the

Metatarsus be connected. Accordingly, the other screw can be screwed into the metatarsus and engage with a screw thread in a thread in the metatarsus. The pulling force introduced into the ground cross-member, inter alia via the clamp, can then be transmitted via the screw to the metatarsus. The formation of this further fastening configuration of ground traverse, further screw and metatarsus can advantageously prevent tearing of the metatarsus of the ground traverse info lge a fall of the transport and storage container. Thus, transverse forces acting on the midfoot can also be introduced into the ground crosspiece via the additional screw. It has proven to be particularly advantageous if the middle feet are formed of a plastic material. Such middle feet are particularly stable, insensitive to moisture and can be produced inexpensively. Alternatively, the middle feet may be formed of metal, wood or other suitable material.

In the middle foot, a thread may be formed, in which engages the screw. An internal thread in the metatarsus may be cut or molded by the screw itself. Also, the metatarsus may be formed so that it already has a thread. Preferably, an indentation, for example a countersink or a bore, can be formed in the middle foot in order to ensure reliable guidance and positioning of the screw during assembly.

The subframe may have two opposite middle feet, which are connected to each other via the floor crossmember. Thus, the bottom of the undercarriage by means of the floor crossbar particularly simple be supported or stabilized. Also, the bottom cross-piece can connect three middle feet together, wherein the third mid-foot can then be fixed in a middle between the two outer middle feet on the floor crosspiece. Alternatively, it is also possible by means of the floor crossmember to connect two middle feet, which are arranged relative to each other with respect to the floor at right-angled side edges of the floor, so that the floor cross-member extends diagonally below the floor.

In the transport and storage container for liquids according to the invention, which is equipped with an inner container made of plastic, with a closable filler neck and an emptying nozzle for connection to a removal fitting, the inner container is on a bottom of a pallet-like underframe according to one or more of claims 1 arranged to 15.

1 to 5 show a first embodiment of a transport and storage container 10 in different views, in particular, an inner container of the transport and storage container 10 is not shown here in detail, so that only a base frame 1 1 of the transport and storage container 10 is shown , The underframe 1 1 is essentially formed of an outer shell 12, a bottom 13 and corner feet 14 and arranged between the corner feet 14 center feet 15 and located between the middle feet 1 5 bottom cross member 16. The corner feet 14 and the middle feet 15 are further arranged on skids 17 and 1 8. The bottom 13, the corner feet 14, the middle feet 15, the bottom cross member 16 and the skids 17, 1 8 together form a pallet 19. The arranged on the pallet 19 outer shell 12 is formed of intersecting, horizontal and vertical bars 20, 2 1 made of metal, in particular a lower, resting on the pallet 1 9 grid bar 20 of the outer shell 12 is formed as a tube 22 which over Attachment points 23 with the corner feet 14 and attachment points 24 is connected to the middle feet 15.

A synopsis of Figs. 2 and 4 shows an attachment point 24 with a metatarsus 1 5, wherein in the sectional view shown in FIG. 4, the outer shell 12 and the tube 22 is not shown. The floor cross member 16 is formed from a profile body 25 made of metal, and is arranged on an upper side 26 of the midfoot 15. Next, the bottom 13 is placed above the bottom cross member 16 in an edge region 27 of the midfoot 15 on the bottom cross member 16 and the profile body 25. A clamp 28 is also arranged in the edge region 27, wherein the clamp 28 has an upper leg 29 and a lower leg 30. In the upper leg 29 is a Durchgangsö opening 3 1 and the lower leg 30, a through hole 32 is formed. In the area of the passage opening 32, a nose 33 is further formed on the lower leg 30. The lower leg 30 is inserted into a gap 34 between the upper side 26 of the middle foot 1 5 and a lower side 35 of the profile body 25, wherein the nose 33 engages in a passage opening 36 of the profile body 25. A web 37 connecting the legs 29 and 30 of the clip 28 abuts against an outer edge 38 of the bottom 13. Further, in the bottom 13 is also a Durchgangsö opening 39 is provided, wherein a screw 40 through the Durchgangsö opening 3 1, 39, 32 and 36 passes through in the Metatarsal 15 is screwed. The inner diameter 41 to 44 of Durchgangsö opening 3 1, 32, 36 and 39 are dimensioned so large that a sufficiently large clearance is formed relative to an outer diameter 45 of the screw 40, which is in contact with the screw 40 in the inner diameter 41 to 44 prevented. The same applies to the not shown in detail Durchgangsö opening 36 in Pro filkörper 25. A now info lge a fall of the transport and storage container 10 on an outer edge 46 of the midfoot 15 caused shock-like force leads in turn to a deformation or slipping of not here illustrated inner container within the outer shell 12, so that the outer shell 12 in turn exerts a tensile force in the direction of a longitudinal axis 47 of the screw 40 on this. The tensile force acts directly on a screw 48 of the screw 40 with the middle foot 15. Since the tube 22 between a screw head 49 and below of the upper leg 29 and the midfoot 15 is arranged, the outgoing of the tube 22 pulling force acts on the bracket 28, so that a part of the tensile force on the bracket 28 can be derived because the bracket 28 with the lower leg 30, the profile body 25th intervenes. The force acting on the screw 48 tensile force is thus reduced by the derived via the bracket 28 tensile force, which reduces the risk of tearing the screw 40 from the metatarsus 15. Also, the tensile force derived via the bracket 28 can be introduced via the nose 33 on the lower leg 30 of the bracket 28 in the profile body 25. In addition, the upper leg 29 serves for the screw head 49 as a support surface 50, so that it may be necessary to dispense with the use of a washer here.

A synopsis of Fig. 6 and 7 shows a sectional view of a base frame 5 1 of a transport and storage container not shown here in the region of a metatarsus 52. The basic structure of the transport and storage container and the base frame 5 1 corresponds to that in Figs to 5 shown transport and storage container with the exception of the differences described below. An outer casing 53 of the lower frame 5 1 rests with a tube 54 on a peripheral bearing surface 55 of a base 56 of the lower frame 5 1. The bottom 56 is in turn in an edge region 57 of the metatarsus 52 together with an integral profile body 58, which forms a bottom cross member 59, on. The bottom crosspiece 59 and the profile body 58 connects the metatarsus 52 with an opposite metatarsal not shown here. Further, a screw 60 is provided, which is hammered into a top 61 of the middle foot 52 made of plastic material and thus forms a screw 62. The screw 60 thus connects the outer jacket 53 via the tube 54 to the bottom 56, the profile body 58 or the bottom crosspiece 59 and the middle foot, whereby a fastening configuration 63 is formed in an attachment point 64 on the middle foot 52. Further, in the context of the fastening configuration 63, a clamp 65 is provided, which surrounds the bottom cross member 59 or the profile body 58 on an underside 66 and the outer jacket 53 or the tube 54. In an upper leg 67, a through-opening 68 is formed with a depression 69, wherein a lower limb 70 initially has no through-opening in an unmounted state of the clamp 65. The screw 60 is through the passage opening 68 in the bracket 65, through a through hole 71 in the tube 54, a through hole 72 in the bottom 56, a Durchgangsöff- tion 73 in the profile body 58 and a trained when driving the screw 60 through hole 74 in the lower leg 70th the clip 65 passed. A caused by the above load case of a fall of the transport and storage container pulling force acting in the direction of a longitudinal axis 75 of the screw 60 is introduced as soon as possible via the screw 60 in the metatarsus 53, wherein a part of the tensile force also on the bracket 65th in the profile body 58 and the bottom cross member 59 is introduced as a result of the positive arrangement of the clip or the lower leg 70 below the profile body 58 in this. The screw 62 with the metatarsus 52 is thus relieved of this part of the tensile force.

In addition, a second screw 76 is provided, by means of which the profile body 58 is connected to the middle foot 52 by screwing. The screw 76, the profile body 58 and the middle foot 52 thus form a further fastening configuration 77, which serves for the secure arrangement of the midfoot 52 on the profile body 58.

A synopsis of Fig. 8 to 1 1 shows a sectional view of a base frame 78 of a transport and storage container not shown here in the region of a metatarsus 79. The structure of the transport and storage container and the undercarriage 78 corresponds to those in FIGS. 6 to 7 shown transport and storage container with the exception of the subsequently described differences. A bracket 80 surrounds here a tube 8 1 of an outer shell 82, a bottom 95 and a profile body 83 of a floor cross member 84. A screw 85 passes through the bracket 80, the tube 8 1, the bottom 95, and the profile body 83 and is screwed into the metatarsus 79. The bracket 80 has an upper leg 86 and a lower leg 87, which are connected via a web 88. An end 89 of the upper leg 86 is angled, so that the clip 80 can be easily pushed onto the tube 8 1. Further, in the upper leg 86, a through opening 90 is formed with a recess 91 for guiding the screw 85. In the lower leg 87, a slot-shaped passage opening 92 is formed with a just such depression 93. The slot-shaped passage opening 92 allows an optional arrangement of

Screw 85 in the context of the passage opening 92 such that a longitudinal axis 94 of the screw 85 passes through both through holes 90, 92. The passage opening 92 is formed so that the

Screw 85 when screwed into the Durchgangsö opening 92 this deformed.
