Pivotal points (1) of the pivot bearing are arranged within a wall volume of the side panels in a direction of an inner side of the container. Lifting brackets (5) are connected with an upper side of the side panels.

Description

The The invention relates to a transport and storage container for Transport and storage of compressed gas cylinders.

Transport- or storage containers are intended for the transfer of piece goods, such as As compressed gas cylinders, during transport and to facilitate storage. Generally known in this context the so-called pallets on which piece goods held together in smaller or larger quantities From the place of manufacture with lifting means initially mostly on trucks implemented and transported away and then often to other means of transport such as train or ship to be redeployed and transported, until finally in a warehouse for sale or for sale Further processing and be removed from the pallet.

such Transport and storage containers are also for the transport of Compressed gas cylinders from the filling site to the distributor and possibly back to the place of filling and for storage in the distribution company until delivery to the users. It acts it is very stable trained container with a horizontal right pallet floor, at the side edges at least at three sides massive latticed side walls made of sectional steel rise upright.

Such a container is z. In EP 0 104 471 B1 described and illustrated.

Out For safety reasons, both the pallet base as well as the sidewalls be very stable, around heavy compressed gas cylinders even under extreme transport conditions, taking into account the dangerous goods regulations "road" are able to hold safely in the container.

The provided with side walls transport and storage containers, as well as in EP 0 104 471 B1 described container for compressed gas cylinders, have the disadvantage that they need a lot of space for their own intermediate storage and for their eventual transport in the empty state in the empty state.

Collapsible transport and storage containers have therefore already been developed for smaller and lighter piece goods. Such a container is z. B in EP 1 201 549 B1 described and illustrated. In this container, the vertically rising from the side edges of the pallet, designed as a lightweight wire mesh side walls are hinged to the side edges of the pallet and on top of the pallet one above the other folded. Held the side walls in the vertical position by at the corners of the pallet vertically towering stable corner posts made of section steel, which can be pivoted to the pallet base mounted pivot bearing also in a horizontal position, parallel to the side edges on the pallet floor. This collapsible transport and storage containers is completely unsuitable for the transport and storage of heavy compressed gas cylinders, and recognizable for the foldability of this container technical solutions regarding the pivotal mounting of the side walls and the Eckholme and for their mutual locking in their vertical arrangement can be for a for collapsible cylinders suitable collapsible transport and storage containers neither take nor modify in a simple manner. This has the following reasons: The surface of the pallet base of a transport and storage container for compressed gas cylinders is relatively small in order to limit the total weight of the filled with compressed gas cylinders container so that it is still feasible even by conventional lifting means such as forklifts, etc. But this means that in the usual manual placement of the container by means of a bar cart in the interior of the container is little freedom of movement and z. B hinder all work from the container walls inwards and from the bottom of the container upwards (from hinges, bolts, etc.) to work and pose an accident risk. Only so it is understandable that so far no collapsible transport and storage containers for compressed gas cylinders have been created, although collapsible transport and storage containers for lighter and smaller piece goods have long been known.

Of the Invention is therefore the object of a transport and To provide storage containers for compressed gas cylinders, its side walls collapsible on the pallet floor are and at the same time the high safety requirements to transport and storage containers for compressed gas cylinders does justice.

The The object is achieved by the characterizing Characteristics of claim 1 solved.

advantageous Embodiments of the invention form the features of Subclaims 2 to 6.

The invention will be described below with reference to a preferred embodiment in conjunction with the drawings of the 1 and 2 be explained in more detail.

1 shows a collapsible transport and storage container for compressed gas cylinders according to the invention in a ready for the transport and storage of bottles state with vertically unfolded side walls in a perspektivi representation and

2 shows an enlarged view of one of the provided for the spars of the two longitudinal side walls pivot bearing also in a perspective view.

In 1 an inventive transport and storage container T for compressed gas cylinders is shown in transport ready state. For reasons of clarity, the representation of the compressed gas cylinders has been dispensed with.

On the pallet-like bottom plate B, the two longitudinal side walls L are pivoted about the pivot axes S to the bottom plate, wherein the pivot points 1 the pivot axes S are disposed within the volume of the longitudinal side walls L. In this way, it is ensured that protrude into the interior of the transport and storage container T according to the invention no projections, which in the manual assembly of the container with compressed gas cylinders, eg. B. when driving the spatially very cramped base plate B of the container with a dowel hinder the work or pose a risk of injury.

How out 1 is clearly visible, are in an advantageous embodiment of the transport and storage container T according to the invention, the pivot points 1 the pivot axes S eccentrically offset within the volume of the longitudinal side walls L to the interior of the transport and storage container T out. In this way, it is additionally ensured that the longitudinal side walls L are already in a relatively stable position after erecting in the vertical position, ie even before raising the rear side wall R and connecting and bolting the longitudinal side walls L to the rear wall R, ie they remain in the vertical position without having to be held. If, in fact, the longitudinal side wall L is to be folded inwards from its vertical end position, the weight of the outer wall side, which as a result of the eccentric arrangement of the pivot axis S in the interior of the longitudinal side wall L is considerably heavier than that of the inner wall side, must first pass over the pivot point 1 the pivot axis S are lifted until the longitudinal side wall L can tilt inwards under its total weight. The eccentricity of the pivot axis S thus causes a self-holding effect of the folded in the vertical position longitudinal side walls L. This makes it possible that only one person can bring the transport and storage container T according to the invention in the ready for receiving pressurized gas bottles position without an accident risk the possibly self-folding longitudinal side walls L exists. Of course, some attention is required, as long as the back wall is not yet out of the folded on the bottom plate B horizontal position around the fulcrums 3 brought the pivot axis for the rear wall in its vertical position and by means of cotter pins and / or bolts 2 with the two longitudinal side walls L is firmly connected. After raising and connecting the rear wall R with the longitudinal side walls L is a very stable, suitable for receiving compressed gas bottles collapsible transport and storage container T is formed.

The sake of completeness, the other, known from the non-collapsible transport and storage containers of the prior art components are mentioned, which are also taken in the transport and storage containers L invention: on the tops of the longitudinal side walls L are each two crane eyes 5 welded in order to implement the collapsible transport and storage container L in a known manner with lifting equipment can.

Furthermore, at the front transverse edge of the bottom plate B a Flaschenaufrollblech F articulated in a known manner, which in 1 only hinted at. It is, as known from the prior art, for driving the transport and storage container L with the hand truck or for rolling up the bottles by hand folded outwards and forms a Auffahr- or Aufrollrampe in this position. After loading the container with the compressed gas cylinders, the bottle roll F is in the in 1 shown vertical position and secured in this position. When folding the empty transport and storage container T invention, the Flaschenaufrollblech F is folded as the first hinged part inwardly on the bottom plate B. Then follows the back wall R, and further (in the example 1 ) left longitudinal side wall L and finally the right longitudinal side wall L. To ensure an exact horizontal juxtaposition of the side walls, the pivot bearings S for the three side walls, as shown 1 is clearly visible, arranged at different heights, wherein the thickness of the underlying side wall or the sum of the thicknesses of the underlying side walls for the height of the pivot bearing is decisive.

In addition to the well-known bottle straps ensures a safety chain 4 , as also known from the prior art, ensure that the bottles are also secured against falling out of the transport and storage container T forward.

2 is an enlarged perspective exploded view of one of the inside of the longitudinal side walls L eccentric to the inside of the transport and storage container T staggered pivot bearing S.

The spar H of the longitudinal side wall L is shown in a vertical position. At the bottom of the Holmes H is a vertically pointing down holding web 7 welded, and into a hole 8th in the jetty 7 is a spacer made of round material 9 welded, which ensures that the spar H with a fixed to the base plate B spar carrier 10 exactly aligns when he is with the jetty 7 in the spar carrier 10 between two opposite bearing bores 13 is introduced. In the spacer element 9 is an eccentric bearing bore 11 for receiving a bearing pin 12 brought in. When inserting the with the spacer element 9 provided Haltesteges 7 in the spar carrier 10 will after the eccentric bearing bore 11 of the spacer element 9 with the opposite bearing bores 13 in the spar carrier 10 was aligned, the bearing pin 12 inserted. The spar H of the longitudinal side wall L now sits in a vertical position with its underside on the top 15 of the spar carrier 10 on. The eccentric arrangement of the bearing bore in the spacer element 9 ensures that the outer side of the longitudinal side wall L holds by its predominance over the inner side of the longitudinal side wall in the vertical position, as long as the longitudinal side wall L is not pivoted so far in that the greater part of the total weight of the longitudinal side wall L on the pivot point of the bearing pin 12 out to the inside of the container. In this way, it is ensured that the longitudinal side wall L is in a vertical position in a stable condition so that when due attention and a person alone the transport and storage container T according to the invention can open in the suitable state for transport and storage, without getting to be exposed to an unpredictable accident risk.

The illustrated eccentric arrangement also ensures that when folding the longitudinal side walls L from the vertical to the horizontal position, the undersides of the spars H, in the vertical position on the top of the spar carrier 10 sit, first lift off the rail carrier, so that despite the usual manufacturing tolerances at this point no friction occurs and no wear is expected.
