Description

Collapsible and Stackable Container The invention relates to on a new development of a logable and stackable container, as it can be used in many businesses, especially for transport and selling fruits and g-musts instead of the well-known containers, such as crates or "pallets".

Such containers have to accommodate different objects meet a large number of requirements, which are often difficult to reconcile with one another are.

So they have to be stable and not deformable at the same time, if they are erected or "unfolded" in container form; they must on the other hand easily collapsed into a small entire volume. You need to get out hinged elements with Be-75 (38 + 39 + 42) L-r (7) fortification and using holding and locking devices that cope with the heavy loads have grown to which the containers are subjected; nevertheless, these holding means must and locking devices be particularly simple. The containers have to be folded up or in the assembled state and they have to deal with different Use a large filling and have it handled. After all, they should have one too offer a certain aesthetic appearance.

Of the known containers of this type, such as pallets etc. made of wood, No metal or plastic fulfills all of the conditions.

The invention thus encompasses a number of M-rksalen, the the advantages resulting from the above statements in their interaction offer in their entirety. A first group of these characteristics, but also individually Can be used in combination are: collapsible and stackable containers1 characterized by a) a base part, which consists of a with raised edges provided floor and slightly protruding feet; b) two in the form of one Tryptics with a central wall connected to the side walls in the two vertical Tryptic joints relative to the middle wall, as well as together with the middle wall - if this is hinged to the base - pivotable about its horizontal lower edge and fit exactly to the base in the folded position or iii insert iliii; ) vierti wall, which has a lockable train, 3-opening having and by means of connecting means provided on the two tryptic side walls these one walls can be firmly connected; d) on the upper edges of the tryptic side walls provided raised shoulders as centering organs for the feet of an attached Container of the same type.

In order to be able to close the access opening of the fourth wall, you provide movable closing organs, such as animals or flaps, which the container are adapted.

So far, such closing organs were only known adapted ones Swellable door or lid and did not involve convenient handling; certain Closing organs had to be completely removed to gain access to the container To get this, all of them needed a very large free space to open them Room etc.

The subject of the invention is also a "pallet warld attachment" with attached or built-in mobile animals for a pallet together with this form the container, the one from at least two wall parts pivotably connected to a horizontal dome joint has fourth wall, each of these wall parts in retaining hooks of the cross winds can be attached.

But it can also be used to close the one provided in the fourth wall Access opening provided a double door with two individual swing-open doors its door leaves in guide rails arranged on the two side walls are retractable.

The doors each consist of a closing door leaf and one Leadership door field, which is preferably the same Height like that Have peripheral walls of the container or the wall attachment and of which the first Wing that can be completely pulled out of the guide rails, half the width the access opening can complete, while the guide door panel part is not off emerges from the guide rails. This other part then has a length that of the Difference between the width of the container base or the wall attachment and the Width of the first final door leaf corresponds, so that each formed in this way The door is exactly the same width as the side wall of the wall attachment and the entire door lies in its inserted position in the side wall, while in the closed position only the inner door part remains within the guide rails, while the final part Door leaves around a vertical hinge between the two door parts in front of half of the Opening or the access opening in the fourth container wall is pivotable.

After closing the two doors you can open them with the help of a Set bolt or other suitable locking device.

In practice you can use such a wall attachment of a container, which consists of three completely closed wall parts and one wall part with an opening consists, fold up completely with its two closing doors described above; the wall attachment can be unfolded and assembled again for its use, the shape retention and the rigidity by inserting or adapting the lower edge of the attachment is secured in or on the edge part of the base or a pallet.

To adapt or fit the lower part of the wall attachment or to make the edge of the base or the pallet even more "tighter" can be a pull rod or Stiffening bar on two opposite one another Fasten container sides or wall attachment sides so that they are at the same height as the pallet or to contract or support the pedestal and thereby force a to exert high pressure on the corresponding edges of the pallet or base.

It is also known in high-volume department stores, cubic or cuboid containers made of metal wire mesh that are stacked on top of each other open to the front; From these containers, the buyers take the access opening the selected goods that you want to purchase. It is clear that a such a stacking of storage containers, that of a storage in place and position, in no way corresponds to a logical sequence of work, since everyone Containers in the stack of the others completed and independent of the others is. The customers of the department store will first l * -ren the lower container, then must, in order to remove goods from the next container, the stack of felled containers be raised, m to be able to pull out the empty container, then measure the stack The bottom container of the previously raised container is lowered again and again lowered stack arrives in the removal position.

Finally, the invention also makes it possible to eliminate this disadvantage and to avoid any handling of the container in the buyer's area * without a substantial change in the construction of the container is required. After this special training can be obtained at the moment when full containers are stacked on top of one another, create a connection between each container with the container below it * a steady transfer of the contents of the upper container into the one below Achieve container.

In detail, the measure according to the invention consists in a certain * containers that can be stacked one on top of the other with its own kind in that one Provides a flap in the bottom of the container that preferably opens downwards, which can be opened from the outside after a stack of full containers.

It should be readily apparent that when the After opening their bottom flaps, there is no sudden and hard fall of the containers Container contents can enter the container below, resulting in a Damage to the goods could result. On the contrary, it occurs when removing from the front of the goods from the lower container in this a collapse of the goods one that are in the lower container and slide or sink accordingly new goods from the upper container, each from each of these upper containers Goods slide steadily and those that have stepped out of the container below or add goods taken from the bottom container. This relatively "gentle Subsequent delivery of the goods makes it possible to use the bottom flaps not only on containers to use for ~ goods with little risk of breakage, such as cans, but also for all other objects that are generally not perishable very easily; Such goods can also be stored in several stacked containers house for sale.

With the help of a special container set up for continuous make-up One can given a particular sales sector with a relatively large supply Equipping goods or articles and adding to this stock without major work, since Yes Only the top container that empties first is changed; you can replace this top container with a full container, without Touch or handle the lower containers that are still partially full have to. In this way, a logical and easy-to-use handling is achieved in the loading or refilling of sales containers.

All of the features mentioned above and also other special features and advantages will be apparent from the following description relating to the Drawing refers; in the drawing: Fig. 1 to 5 show a container pallet " according to the invention in different positions of folding and unfolding; 6 and 7 show the stacking of two such "pallets"; Figures 8 and 9 the type of closure and locking of an access opening in a side wall; 10 shows a schematic perspective illustration of another embodiment a wall attachment according to the invention in a built-up arrangement, but without the Pallet serving as a base; 11 shows a schematic plan view of the wall attachment according to Fig. 10; FIG. 12 is a schematic front view of the wall attachment according to FIG 10 and 11; Fig0 13 a stacking of containers, which the last have above-mentioned features according to the invention and Fig0 14 the bottom of a trained in the manner described container.

In the first to be treated Figo 1 to 5 it can be seen that each Container "pallet" or any collapsible stackable container according to the invention has a base part or base 1 which contains a horizontal base 2, supported by four feet 3 and limited by four upstanding edge parts 4. the end Fig. 1 can also be seen that after its collapse of the invention Container is housed completely within this base part, do h., It protrudes nothing beyond the upstanding edge parts 4 of the base.

The container part housed in this way in the base, the is designated as a whole by 5 in FIG. 1, consists initially of a "tryptic" 6 (Fig. 2 to 3) and a front foldable fourth wall 7 (Fig. 3 and 4). The "Tryptik" can be swiveled around a horizontal floor hinge in the middle wall, while the two side walls 6 'can be folded inwards like a tryptic (Fig. 2) and can be swiveled outwards at right angles (Fig. 3) to over support brackets 8 to be supported on the edges 9 of the edges of the floor or base 1.

After setting up the tryptic, you can set up the fourth wall 7, which - as can be seen clearly from FIGS. 4 and 5 - consist of two wall parts 10 and 11 composed, which have dome swivel joints at their lower edges and after When they are opened, they can be hung on hooks on the front Edges of the side walls 6 'of the tryptic are provided.

After the pallets or containers have been set up or unfolded these are completely rigid and can carry a larger stack of identical containers. Figs. 6 and 7 show the means of such a stacking while saving space and allow with the greatest possible certainty.

The upper edge of each side wall 6 'of the tryptic 6 has a middle one raised shoulder 12, which on each side of the edge space to place one of the Can feet 3 of the container placed above. On the other hand, the feet extend 3 noticeably outwards, so that they, instead of on the corresponding edge, only with one Sit on the edge, rest securely with its horizontal zone 13, which is firmly on the curve of the upper edge. The correct mutual position of the stacked Container is ensured in this way.

8 and 9 show the suspension arrangement for the front wall parts. Each wall part 10 or 11 is through at its lower pivot joint or hinge Eyes or loops 14 of elongated shape articulated on a hinge rod 15. By pivoting or tilting around this rod and then lifting the wall part you bring the bracket 16 of the wall parts on hooks 17 on the front edge of the projecting side walls 6; if you then see the wall parts and their brackets lets sink again, one hooks the wall parts of the front wall 7 so that they in turn are locked and at the same time determine the entire container structure.

You can finally get different inside the container Heights still a. or use several horizontal partitions, especially very slightly at the height of the horizontal hinge on the rod 15, being then a special access to the upper half of the container thereby achieved is that the upper part 11 of the front wall 7 is folded down.

Such horizontal partitions can be used during the empty transport housed together with the walls of the container in the base space above the floor 2 will.

Of course, the container can also be completely broken down into its individual parts be dismantled, then all the articulated rods are independent, for example can be removed from the wall parts or walls, which can be pivoted about these rods.

With reference to Figs. 10 and 12, attention should be drawn to the fact that that in this embodiment according to the drawing a wall attachment for a pallet or a base is made up of four walls 101, 102 according to the invention, 103 and 104, one of which, namely the front wall 101, - an access opening-105 contains. The four walls are hinged along their vertical edges connected, which makes it possible, on the one hand, to fold the wall structure completely flat, on the other hand to build it up on a base pallet P.

According to the invention, the access opening 5 is closed by a double door provided, the features of which are the following: Each individual door or door half consists of two door parts, i. H. a final door panel 106 (and 106 ') and one Guide part or a guide field 107 (and 107 ').

Each door half 106 and 107 (as well as 106 'and 107') is between two Guide rails 108, 109 (and 108 ', 109') slidably attached to the lateral surfaces or walls 103 or 104 are attached; the width dimensions of these door halves are chosen such that in an outermost open position (in Fig. 10 on the right with dashed lines Lines indicated) the door half 106 ', 107t lies completely against the side wall 103, while in the closed position the door leaves 106 'completely out of the guide rails 108t, 109 'is pulled out while the part 107t remains in the guide. A Can be pulled out to the area of the front edge of the side walls of the wall attachment vertical hinge allows the wing 106 'to pivot. In the final position the two wings 106 and 106t can be pivoted in the direction of the Arrow F are brought in the final position, they close the access opening 105 (Fig. 12) each half. You can then, for example, in this position lock with a sliding bolt 3.

At the same time the rigidity of the wall structure and its definition To secure on the pallet P or the base, a rod 112 is provided which by attaching to the opposing walls 101 and 102 as a tensile or support rod acts and presses the walls against the base.

Such a wall structure can expediently be a metal grid structure as they are normally used for warehouse equipment containers or Partition grids are provided, also for goods trolleys and other equipment.

As can finally be seen from FIGS. 13 and 14, 9 has been used of the last inventive feature of each of the illustrated containers 201 in FIG its bottom 202 has a connecting flap 203. This flap is around one of its sides 204 pivots and opens steadily to the extent that the buyer has selected the goods the lower one Remove container. The flap opens fully when the main contents of the upper container have slipped through and into the one below there are correspondingly fewer goods available. It is then sufficient to use the upper container to exchange for a new full container; that buyers or the audience need Not even noticeable of this exchange when the container stack is in one special loading room protrudes, which is located on the floor above.

It should also be clear that such a container training with flap does not depend on the other design of the container in question and is applicable to any container that is assembled into a stack with its peers can be. Corresponding connection flaps can also be used for intermediate dividers Use in one and the same main container.
