The invention relates to a watering and transport device for plants, a frame strut and a method for arranging such a watering and transport device in a manner that saves time and space.
Watering and transport devices for plants of the kind which are used, for example, for delivering and storing potted and garden plants in garden centres and similar sales outlets are known from, for example, DE 202 13 719. When devices of this kind are being transported (back) empty, the problem regularly arises as to how the numerous storage platforms on which the plants had been standing during shipment can now be housed in as compact and space-saving an arrangement as possible on the base platform or on the frame struts so that the best possible use is made of the available cargo space in the delivery vehicles used for this purpose, and so that this process can be conducted in as short a time as possible.
Conventionally, the method adopted for this is that the individual storage platforms are hung one on top of the other in the frame struts in as densely packed an arrangement as possible, i.e. so that a storage platform is hung in the insertion recesses of each individual level. This is very time-consuming and does not make the best possible use of the space which would actually be available in the vertical direction.
It is known per se from DE 28 00 575 C2 to insert the frame struts into the support sockets in a transport position, in which their longitudinal slots are facing each other, or inwards, i.e. in a position which is rotated by 180° compared to the storage position. In this position, a number of storage platforms can be stacked one after the other on the base platform from above, and it is no longer necessary to hang the insertion end portions in the insertion recesses, since they instead extend into/through the longitudinal slots and are received in a hollow space inside the frame struts. This leads to a saving of labour time both in creating the transport position (storage platforms are stacked on the base platform) and in the reverse procedure, in which the individual storage platforms have to be removed and are again hung in frame struts mounted on a base platform, which have of course previously been inserted the other way round or are located in the storage position. This leads to poor stability on the part of the overall device, since the storage platforms are only inadequately mounted on the frame struts.
The invention is based on the object of making an improvement here and providing a watering and transport device for plants in which the storage platforms can be arranged for transport purposes more quickly and at the same time stably, and to indicate a method by which a watering and transport device for plants can be changed from a storage to a transport state and vice versa quickly, in a space-saving manner and stably.
From the device point of view, this object is achieved by a watering and transport device as claimed in claim 1.
It is preferably proposed that at least one ridge is disposed in the region of an end portion of a frame strut. It is helpful if in each case at least one ridge is disposed in the region of each end portion of a frame strut.
It is preferably proposed that at least one ridge is disposed in a central region of a frame strut.
The invention further proposes that the frame struts are arranged in a transport position in which the longitudinal slots of two frame struts associated with a first side of the base platform face each other and their insertion recesses face away from one another, and the longitudinal slots of two frame struts associated with a second side opposite the first side face each other and their insertion recesses face away from one another, and that, in a storage position, the frame struts are capable of being received in the support sockets, in which the insertion recess of the frame struts associated with the first side face each other and their longitudinal slots face away from one another, and the insertion recesses of the frame struts associated with the second side face each other and their longitudinal slots face away from one another, wherein a number of storage platforms are stacked one on top of the other on the base platform, each of which is rectangular and has one mounting member in each corner region, which has an insertion end portion that ends freely, wherein the insertion end portions of one storage platform in each case can be inserted, in the storage position of the frame struts, into four insertion recesses located at the same height and, in the transport position of the frame struts, project into the longitudinal slots, a storage platform being placed on four webs of the frame struts.
It is obviously irrelevant to the invention whether, in the storage position, the frame struts are arranged in such a way that the insertion recesses face towards one another in the longitudinal direction or in the direction of the narrow sides of the base platform. In each case, it is possible to obtain the advantageous transport position of the invention by inserting them rotated by 180°.
It is appropriate to provide that the support sockets have a square socket cross-section.
In addition, the invention proposes that each support socket should be closed off at its lower end by a stop member corresponding in cross-section to its socket cross-section and protruding across the respective lower end, so that several base platforms can be stacked in a centered manner.
Apart from that, it is preferably proposed that the frame struts are made substantially square in cross-section. In the case of a C-shape, the longitudinal slot can, for example, have a width amounting to 20% to 90% of the side length of the square shape, e.g. 50%.
An appropriate embodiment is characterised by the fact that the base platform is provided on its underside with rollers, such as four fixed rollers or two fixed and two steering rollers.
It is advantageously proposed that the insertion recesses in the frame struts should have an alternating first and second shape or contour, so that it is easier to hang a storage platform in horizontally.
It can be provided that the frame struts associated in each case with a narrow side of the base platform are connected in pairs at their free upper ends with one U-shaped plug-in yoke each.
The base platform may have a floor and pan-like peripheral rim.
It is particularly advantageous if an upper rim portion of each support socket, which is located beneath an adjacent insertion end portion of a bottom storage platform stacked in the transport position, is located at such a height above the base platform, e.g. above an upper edge of the rim of the base platform, that there is a vertical space or distance between the rim portion and the insertion end portion of the bottom storage platform, so that the insertion end portions do not rest on the support sockets. When there are a relatively large number of storage platforms stacked one on top of the other, there is then no risk of overloading and deforming the insertion end portions of the bottom storage platforms.
In this context, it can be provided that the support sockets each have, on sides facing each other in the direction of a narrow side or a long side, a cut-out which, in the transport position of the frame struts, runs substantially in alignment with their longitudinal slot and may project into the one insertion end portion of the bottom storage platform in each case.
The base platform can be provided on each of its narrow sides with a protrusion projecting in the longitudinal direction between corner regions of a rectangular basic shape of the base platform. The protrusion may be sectoral, trapezoid or rectangular in shape.
In addition, an overflow may (in each case) be arranged within one or both protrusion(s). The overflow may be height-adjustable in order to define a particular level of liquid within the base platform.
The at least one storage platform can have a floor and a peripheral rim, its outline preferably being substantially identical to that of the base platform.
The base platform may be provided with centring means for a storage platform to be stacked on it. The centring means may in particular be arranged on the protrusions, and may be formed by pins or plate-like members fixed to the inside or outside of the rim and projecting upwards above the rim.
It is preferably proposed that, in the transport position, at least one storage platform is stacked on the base platform the opposite way round to the position when in use, i.e. with its upper side facing downwards.
This is a major advantage, because no rainwater can then collect in the storage platforms. Since the watering and transport devices are stored in the open as rule, water can collect in each storage platform via the drainage system when they are stored for a lengthy time. This is very unpleasant when the storage platforms are needed again. On the other hand, storing them in a covered area is very cost-intensive.
The invention further proposes that the at least one storage platform is provided on its underside with a centring means for a storage platform stacked on top of it in the transport position, i.e. when both or all the storage platforms are stacked the opposite way round. The centring means may be formed by reinforcements which are U or V-shaped in cross-section and run between narrow sides and are fixed to the floor on the underside, and which may in each case terminate in transition regions between corner regions and the protrusion on the storage platform. Alternatively such reinforcements may be provided in the transverse direction, i.e. between long sides.
In addition, it is proposed that the storage platforms may be provided, at their insertion end portions, with two mutually opposing notches with which they can be placed on or hung in webs, optionally in a position for use or, turned upside down, in a covered position, which webs partially bridge the respective longitudinal slots in the frame struts. In this context, it is preferably proposed that, for each frame strut, one or two adjacent webs should be disposed in the region of the end portions of the frame strut.
The object of the invention is further achieved by a frame strut in accordance with claim 16. It is proposed that at least one ridge is disposed in the region of an end portion of a frame strut. It is helpful if in each case at least one ridge is disposed in the region of each end portion of a frame strut. Furthermore, it is advantageous if at least one ridge is disposed in a central region of a frame strut.
From the process point of view, the object of the invention is achieved by a method in accordance with claim 20.
In this respect, it is advantageous for a storage platform in the uppermost position to be placed on webs.
In this method, it is preferably proposed that the uppermost storage platform is placed upside down (covered position), i.e. so that its floor faces downwards and its underside faces up, so that no rainwater can collect in the pans (storage platforms in the covered position instead of the position when in use).
Further benefits and features of the invention will become apparent from the following description of a working embodiment, reference being made to a drawing, in which
Turning first to FIGS. 1 to 3, in which an embodiment of the invention is illustrated. The device 1 first of all has a rectangular base platform 2, which is either intended for standing directly on the ground or alternatively, as shown, may be provided with rollers so that it can be moved around, one of which can be seen in
The base platform 2 has a substantially flat floor 8 and a rim 10 enclosing it like cheeks, so that a surface for holding plant containers is formed on which water or a nutrient solution can stand, up to a certain depth. In order to regulate the level of the liquid, an adjustable overflow 12 is disposed in a corresponding opening in the floor 8, or one overflow is disposed on each of the mutually opposing narrow sides of the floor 8, so that plants stored there can be supplied with water in the best possible way.

As is shown by
There is a stop member 22 inserted in a lower region of each support socket 16 and fastened there, e.g. by welding. The object of the stop members 22 consists, on the one hand, in forming a height stop for the frame struts 20 plugged in from above, so that they are maintained at a fixed height, and on the other hand, in forming a centring means, so that a number of base platforms 2 can be stacked one on top of the other without frame struts 20 plugged in, in which case a region of a stop member 22 projecting up from a support socket 16 in each case engages from above in a support socket 16 of a base platform 2 arranged below it. The stop members 22 could therefore be open, like tubes, or alternatively they could be closed across their cross-section.
On the bottom of each of its long sides, the base platform 2 has a slightly V-shaped stiffener 18, which, on the one hand, serves to increase the static stability and, on the other hand, contributes to ensuring that the base platform, or a laden, complete watering device (

FIGS. 5 to 8 show an arrangement in which a number of storage platforms 40 are stacked one on top of the other in the position when in use on the base platform 2 (in order to hold plant pots, for example, on their top sides). The storage platforms 40, one of which is shown in
FIGS. 5 to 8 show the storage platforms 40 stacked in such a way that each individual storage platform is placed upside down (in the covered position) on the base platform 2 or on a storage platform beneath it, i.e. the floor of the storage platforms faces downwards. Attached to the underside of the floor 41 are bracing profiles 58, U-shaped in cross-section, which increase the load-bearing capacity of the floor or storage platform and at the same time, with their facing edges at the ends, serve as a means for centrally positioning a further storage platform placed on the stack from above. The profiles 58 could alternatively be V-shaped in cross-section in order to improve the centring effect.
As can be seen from the illustrations according to FIGS. 4 to 6 in combination with
The invention thus provides a watering and transport device for plants, consisting of a base platform with four frame struts plugged in. In a transport position (
The transport position thus offers the advantage that the storage platforms can be stacked close together, so that when the full height of the frame struts is used, a larger number can be housed than would be the case if they were hung in the insertion recesses, and, furthermore, the process of placing them in or stacking them takes considerable less time than hanging them in.
As an alternative to the use of a yoke, it can be provided that the insertion end portions 46 of the storage platforms are provided with not one, but two notches 48, 48a, as is illustrated in

The invention has been explained above with reference to a base platform in accordance with
In an alternative embodiment, the storage platforms might be provided with insertion end portions terminating in the longitudinal direction (relative to the rectangular basic shape, i.e. parallel to the long sides 50); in this case, the frame struts 20 need to be arranged rotated in each case by 90° relative to the embodiment shown so that this time, in the transport or storage position, the longitudinal slots or insertion recesses face each other, namely relative to the longitudinal direction of the device. Similarly, with an embodiment of this kind, the cut-outs 30 of the support sockets 16 would have to be arranged such that they face each other when seen in the longitudinal direction, i.e. rotated in each case by 90° compared to the embodiment illustrated, so that they can fulfil their purpose, which consists in ensuring that the insertion end portions of a storage platform stacked at the very bottom in the transport position do not need to bear any load.
