Beschreibung[en]

The invention relates to a supporting device for supporting a branch of a plant, in particular a tomato plant, said supporting device being provided with an elongated body according the pre-characterising part of claims 1 and 5.

In the cultivation of tomato plants it has become apparent that under certain growth conditions during the early stage of the cultivation, for example under dark, humid conditions, the branches or so-called truss stems, which eventually bear the tomatoes, become elongated and thin. When in that case the fruits formed by the tomatoes start growing, there is a danger that such a long and thin branch or so-called truss stem will collapse under the influence of the weight of the tomatoes, as a result of which the flow of sap through the truss stem to the fruits is disturbed, so that the fruits or tomatoes will not fully develop. Thus the tomatoes will generally remain smaller than might be expected under optimal conditions, which accordingly results in tomatoes of a lower quality and thus in a lower yield.

In order to overcome this drawback a supporting device has been proposed, which is built up of an elongated bar-shaped curved means, on both ends of which eyes are secured, in whose boundary edges openings are provided for passing the stem therethrough. (See for example the journal "Tuinderij" No. 68, April 1988, page 41.)

The placing of said supporting means is a time-consuming activity, which must take place at an early stage of growth already, since otherwise these supporting devices cannot be provided without any risk of damaging the branch or truss stem. This implies, however, that in many cases this has to be done before it is possible to detect whether or not there is any risk that the truss stem in question will collapse, so that in many cases the supporting devices are provided to no purpose.

From DE-B-875736 a device for bending branches of fruit trees is known, provided with a plate having a gutter-shaped curved edge and two retaining brackets, which are pivotable along said edge. This device is complicated and costly and is likewise difficult to place.

The object of the invention is to obtain a supporting device of the above kind, which can be placed in a very simple manner, also at a later stage of growth.

According to the invention this can be achieved by a supporting device according claims 1 and 5.

By using the construction according to the invention the supporting device can be readily shifted from one side of the respective branch or truss stem without having to deform the branch or truss stem in an undesirable manner thereby.

The invention will be explained in more detail hereafter with reference to a few possible embodiments of the construction according to the invention illustrated in the accompanying Figures.

Figure 5 illustrates, to the same scale as in Figure 4, the supporting device in a position supporting a branch.

Figure 6 is an elevational view of a second embodiment of a supporting means according to the invention.

Figure 7 is an elevational view of a third embodiment of a supporting means according to the invention.

Figure 8 is a plan view of Figure 7.

Figure 9 is an elevational view of a fourth embodiment of a supporting means according to the invention.

Figure 10 is a plan view of Figure 9.

Figure 11 is a sectional view of Figure 9, along the line XI-XI of Figure 9.

The body of the supporting means shown in Figures 1 - 5 comprises a curved elongaged strip-shaped body 1, which has a thickening 2 near its centre and which tapers off to two narrow point-shaped parts 3 and 4 near its ends, said parts 3 and 4 being curved in the opposite direction to the curvature of the body 1.

The upper ends of two connecting parts or wall parts 5 and 6, seen in Figure 1, which extend at least substantially perpendicularly to the body 1, are connected to the body near the ends of the body 1, at the point where said body 1 blends into the narrowing ends 3 and 4. The extensions of the facing boundary edges 7 and 8 of the wall parts 5 and 6 intersect on the axis of symmetry 9 of the supporting device, on which axis of symmetry 9 also the centre of curvature of the curved strip-shaped body 1 is located.

At their ends facing away from each other the wall parts 5 and 6 are bounded by boundary edges 10 and 11 respectively extending parallel to the respective boundary edges 7 and 8, the extensions of said boundary edges 10 and 11 at least substantially intersecting the free ends of the parts 3 and 4, seen in Figure 1.

Wall parts 12 and 13 extending perpendicularly to the wall parts 5 and 6 join the boundary edges of the wall parts 5 and 6 facing away from the strip-shaped body 1, the curvature of said wall parts 12 and 13 being more or less similar to that of the body 1.

At least substantially rectangular further wall parts 16 and 17 join the ends of the wall parts 12 and 14, via so-called film hinges 14 and 15, near the ends of the boundary edges 7 and 8 facing away from the body 1, in such a manner that said wall parts 16 and 17 can be pivoted with respect to the wall parts 12 and 13 about the pivots formed by the film hinges 14 and 15 extending perpendicularly to the plane of the drawing, seen in Figure 1.

In the position shown in Figure 1 the wall parts 16 and 17 extend from the hinges 14 and 15 respectively in a direction away from the body 1 and towards each other.

The ends of the wall parts 16 and 17 remote from the pivots 14 and 15 are interconnected by means of a wall part 18, which joins the wall parts 16 and 17 by means of film hinges 19 and 20 corresponding with the film hinges 14 and 15. The curved wall part 18 extends more or less parallel to the body 1, as will be apparent from Figure 1.

Near the centre of the wall part 18 an upwardly extending lip 21 is provided on one side of the wall part 18.

The above-described supporting means is preferably a one-piece unit and is for example manufactured of plastic material by injection moulding.

As will furthermore be apparent from Figures 4 and 5, the wall part 18 can be pressed in the direction of the body 1, whereby the wall parts 16-18 pass a position in which they are more or less in line, and whereby also the body 1 takes up a flatter position than in the unloaded position shown in Figure 1. When the wall part 18 is pressed further in the direction of the body 1, the wall parts 16-18 will pass a so-called dead centre and reach the position shown in Figure 5 thereby.

Before or while the wall part 18 is moved in the direction of the body 1 in the above-described manner the supporting means described can be slid onto a branch to be supported from one side of the branch in question, perpendicularly to the longitudinal direction of said branch, so that in the eventually closed position the supporting means will be secured to the branch, whereby, dependent on whether a thicker branch 22 or a thinner branch 23 is concerned, said branch extends through the supporting means in the manner shown in Figure 5. It will be apparent that the branch 22 or 23 is thereby confined between the lip 21 located on one side of said branch and the wall parts 10 and 11 located on the other side of said branch.

Thus, by using the above-described construction according to the invention, a supporting device has been obtained which can be placed in a simple manner, by means of which supporting device an effective support of a branch of a plant can be effected.

The body of the supporting device shown in Figure 6 comprises an elongated strip-shaped curved body 24. Three wall parts 26, 27 and 28, which extend perpendicularly to the body, are provided on the side of the body remote from the centre of curvature of said body, near the ends and near the centre. Wall parts 29, 30 and 31 respectively, extending at least substantially parallel to the body 24 join the ends of said wall parts 26, 27 and 28 remote from the body 24. The wall parts 29 and 31 located near the ends of the supporting device are provided with extensions 32 and 33 respectively, which extend in a direction away from each other. Lip parts 34 and 35, which extend parallel to the wall parts 26 and 28, are provided on said extensions, at the sides of the wall parts 29 and 31 remote from the wall parts 26 and 28, said lip parts 34 and 35 projecting from below the wall parts 29 and 31 respectively or the extensions 32 and 33 thereof at the same side as the wall parts 26 and 28.

The free ends of the extensions 32 and 33 are furthermore knurled at their sides facing away from each other, which knurlings make it easier to grip said extensions 32 and 33 with the ends of for example the thumb and finger of a hand.

It will be apparent that also this supporting device shown in Figure 6 can be shifted onto a branch from one side of said branch in a simple manner, perpendicularly to the longitudinal direction of the branch in question, whereby said branch will abut against the wall parts 26-28 and is confined between the body 24 and the wall parts 29-31 respectively, as well as between the wall parts 26 and 28 and the lips 34 and 35.

In order to make it easier to provide said supporting device, the device may be bent into a straighter position, if desired, by moving the knurled ends of the extensions 32 and 33 towards each other.

It will be apparent, that also this one-piece supporting device, which is made of a suitable, slightly resilient plastic material, can be manufactured and placed on a branch in a simple and efficient manner, thereby effecting an effective support of the branch in question.

The device shown in Figures 7 and 8 comprises a strip-shaped curved body 35, which extends perpendicularly to the plane of drawing of Figure 7. A wall 36 extending perpendicularly to the strip-shaped body 35 joins a longitudinal edge of said strip-shaped body 35.

Hooks 37 are provided near the ends of said wall part.

Near the centre of the wall part 36 a connecting rib 38 extending perpendicularly to the wall part 36 and parallel to the body 35 is connected to the boundary edge remote from the body 35. Arms 40 are pivotally connected, by means of film hinges 39, to the boundary edges of the connecting rib 38 extending perpendicularly to the wall part 36.

As is apparent from Figure 8 the width of the arms 40 is equal to the width of the body 35.

The ends of a connecting arch 42, whose width is smaller than that of the arms 40, as is apparent from the top view of Figure 8, are coupled to the arms 40, by means of film hinges 41, at a short distance from the free ends of the arms 40

Two strip-shaped projections 43 and 44 respectively extending in the direction of the body 35 are secured on either side of the free ends of the arms 40, said projections being slightly staggered relative to each other, seen in the longitudinal direction of the arm 40 in question, as will be apparent from Figure 7.

Furthermore recesses 45 are provided in the free ends of the arms 40, at the side directed towards the wall 36.

As is furthermore apparent from Figure 7, the connection between the connecting rib 38 and the wall 36 and the connection between the wall 36 and the body 35 respectively may be reinforced by connecting ribs 46.

Furthermore one or more projecting cams 47 may be provided on the boundary edge of the elongated body 35 remote from the wall 36.

It will be apparent that in the open position of the supporting device shown in Figures 7 and 8 a branch to be supported can be placed on the elongated body 35 from an open side of the device without any difficulty. The branch will thereby come to lie on the elongated body 35 and between the side wall 36 joining said elongated body 35 and the cams 47 that may be provided.

Then a pressure force can be exerted on the connecting part 42, in the direction according to the arrow P. The arms 40 will pivot about the pivots 39 thereby, to a position in which the arms 40 extend at least substantially parallel to the curved body 35. The projecting arms 44 abut against the side of the wall part 36 remote from the body 35 thereby. The arms 43 extend in front of the branch lying on the body 35, so that said branch will be further retained between the wall part 36 and the arms 43. When the supporting device closes the hooks 37 will move through the recesses 45 and spring out slightly, and subsequently hook behind the ends of the arms 40, thus ensuring adequate locking of the arms 40.

The supporting device shown in Figures 9 - 11 comprises an elongated strip-shaped body 48, which is joined by regularly spaced, substantially triangular wall parts 49, which gradually widen in a direction away from the elongated strip-shaped body 48. Ribs 50 extending perpendicularly to said wall parts 49 and parallel to the body 48 join the ends of said wall parts 49.

The wall parts 49 may be reinforced at their sides remote from the ribs 50 by means of ribs 51 extending perpendicularly to the wall parts 49. The connection between the wall part 49 and the body 48 and the ribs 50 respectively may be reinforced by means of small ribs 52.

Protecting cams 53 may be provided on the facing sides of the boundary edge of the body 52 remote from the wall parts 49, as well as on the free ends of the ribs 50.

As is apparent from Figure 9 the facing sides of the wall parts 49 are furthermore provided with projecting hooks 54.

This resilient supporting device of plastic material, which may also be in a single piece, can be straightened, if desired, in order for a branch to be placed, whereby the device can be slid onto the branch in question from the open side, whereby the branch will be retained between the body 48, the ribs 50 extending parallel thereto, the wall parts 49 and the cams 53. When under the influence of a load applied the supporting device is bent any further from the unloaded position shown in Figure 9, the hook-shaped parts will engage each other more firmly and prevent undesirable distortion of the supporting device.

Although hereinabove mention is made in particular of the use of the supporting device with tomato plants, it will be apparent that the supporting device according to the invention can also be used with other plants.
