[0001] The present invention relates to a diversion barrier tree trunk protection device for protecting a tree trunk and / or a branch from external mechanical influences, such as mechanical friction forces, according to the preamble of patent claim 1.

[0002] KR 10 1 352 046 B1 relates to a tree guard for a grass cutting machine, comprising a plastic plate having a length which surrounds the lower part of a tree, which is rolled into a cylindrical shape to surround the tree and whose outer side, facing the outside of the tree, is rubbed by a grass cutting blade of a grass cutting machine; a wire mesh which is inserted into the plastic plate to prevent the grass cutting blade of the grass cutting machine from penetrating the plastic plate; a heat-insulating material which adheres to the inner side of the plastic plate, facing the outer skin of the tree, and keeps the outer skin of the tree warm; a cover which surrounds and protects the plastic plate, into which the heat-insulating material and the wire mesh are inserted, and which, together with the plastic plate, forms a cylindrical shape to surround the tree.and fastening cords attached to both ends of the cover, securing both ends of the cylindrical cover. The plastic plate is rubbed against the grass cutting blade, so that the lower part of a tree can be protected when cutting grass.

[0003] DE 86 34 349 U1 describes an invention for holding a tree trunk to be moved from a standing tree.

[0004] DE 295 00 457 U1 concerns a roll-up wooden mobile fence which complies with RAS-LG 4 and is nevertheless light, handy and stable, requiring little transport space and load due to its roll-up capability using thin, lightweight fence slats.

[0005] The diversion barrier tree trunk protection device described here (also called tree trunk protection device for short) comprises, for protecting a building trunk and / or a branch from external mechanical influences, such as mechanical frictional forces, at least one diversion barrier which can be guided around a circumference in the radial direction around a tree trunk, at least one holding element for releasably fixing the diversion barrier to the tree trunk, wherein the holding element is designed such that the diversion barrier can be pressed against the tree trunk, in particular solely by the holding element, so that tree trunks and / or undergrowth can be guided past the tree trunk along the diversion barrier, in particular wherein the diversion barrier or at least a part thereof is inflexible.

[0006] According to at least one embodiment, the diversion barrier tree trunk protection device described here comprises a flat base element which can be laid at least partially around the tree trunk. Preferably, the flat base element can be guided around the tree trunk, in particular can be tensioned and / or adjusted.

[0007] In the context of the present invention, "flat" refers to such a base element that is designed in the form of, for example, a tarpaulin, but in any case has a thickness that is negligible compared to the surface of the base element; for example, the thickness of the base element is at most one, preferably at most two, and particularly preferably at most three millimeters. The tarpaulin can be a flexible fabric.

[0008] Furthermore, the tree trunk protection device described here comprises at least one, preferably at least two, reinforcing elements which are arranged detachably or non-detachably on the base element.

[0009] The reinforcing elements preferably serve to at least partially clamp the base element, so that the base element forms a mechanical reinforcement in at least one direction, for example also in at least two directions, along the flat base element by means of the reinforcing elements, which is, however, dimensioned such that the reinforcing elements can also be applied at least partially to an outer surface of the tree trunk, for example in the vertical direction, i.e. in a direction substantially parallel to the growth direction of the tree trunk, without the reinforcing elements suffering mechanical damage.The reinforcing elements are therefore of such a thickness and / or made of such a material that when the base element is laid flat around the outer surface of the tree trunk, the reinforcing elements do not suffer any structural damage and at the same time reinforce the base element in at least one direction around the tree trunk. In this way, it is avoided that the flat base element does not collapse when folded along the outer surface of the tree trunk, but has its own stabilization in at least one direction without further external mechanical reinforcements. For example, the reinforcing elements are arranged in a comb-like manner on the base element and each guide the base element in one direction parallel to one another from one end of the flat base element to another opposite flat base element.For example, the reinforcement elements have, among other things, the task of exerting a certain contact pressure on the root base in order to prevent it from being “pushed up” by the tree trunk passing by.

[0010] The guide form of the reinforcement element mechanically reinforces the base element in its flat design so that it can be laid, preferably flush, around the tree trunk.

[0011] According to the invention, the diversion barrier has at least one guide element which can be applied to the tree trunk by means of at least one application element.

[0012] According to at least one embodiment, the reinforcing element is designed such that, together with the flat base element, it at least partially adapts and / or is adaptable to the external shape of the tree trunk. The present application essentially addresses the problem of • In soil-friendly forestry work, after the trees have been felled, the felled tree trunks are usually removed from the forest using cable winches. This is referred to as "log hauling." During hauling, it can happen that the trunks lying on the ground "drag" past existing trees, damaging their bark. If the damage is greater than a hand's breadth, the tree can no longer heal itself. The result is significant weakening of the tree, fungal infestation, and ultimately a significant loss of value due to the inferior wood quality in the ground trunk area. • Solution: To prevent such injuries, a "protective cover" can be attached around the endangered tree. This protective cover consists, for example, of the following components: ◯ Tarpaulin: The covering is based on a tarpaulin ▪ whose surface has very low friction ▪ which has been sewn in such a way that it spreads in the lower part in order to cover root runners ◯ Several spring steel strips (approximately 40 mm wide and 600 mm long) sewn vertically into the tarpaulin ensure that the tarpaulin is pressed firmly into place, especially in the area of ​​the root base. This prevents a passing tree trunk from pushing the tarpaulin up or dislodging it, but simply slides over it. ◯ The protective cover is attached using two suitable tensioning straps.

[0013] According to at least one embodiment, the diversion barrier tree trunk protection device for protecting a tree trunk and / or a branch from external mechanical influences, such as mechanical friction forces, comprises at least one flat base element which can be laid around the tree trunk at least in places, and at least one, preferably at least two, reinforcing elements which are arranged detachably or non-detachably on the base element, wherein the reinforcing element mechanically reinforces the base element in its flat design so that it can be laid, preferably flush, around the tree trunk.

[0014] In at least one embodiment, the reinforcing element is designed such that, together with the flat base element, it adapts and / or is adaptable at least partially to the outer shape of the tree trunk.

[0015] According to at least one embodiment, the flat base element is designed in the form of a tarpaulin. The diversion barrier can be arranged on the outside of the tarpaulin. In such a case, this can also press the reinforcement element against the tree from the outside. In this respect, a combination of the components "tarpaulin + reinforcement element" and "guardrail" is conceivable.

[0016] For the purposes of the present invention, a tarpaulin is understood to mean a cover and / or a fabric whose edge is reinforced by a piping. Alternatively, however, the reinforcing element described here can be designed in the form of a tarpaulin, but the piping can be omitted.

[0017] A piping, in the sense of the present invention, is an edge reinforcement of the tarpaulin, made, for example, of plastic or fabric-covered leather. The piping usually has a round or round-like cross-section and features a wide, flat piping tab for attachment to the outer surface of the tree trunk. This tab connects the tarpaulin and the piping. The piping tab is usually a casing that encloses the piping bead. The piping tab and tarpaulin are usually welded together, rarely sewn (although this is also possible).

[0018] The keder rail is the part of a tensioning mechanism into which the keder is inserted. This is a guide groove, usually round in cross-section, into which the keder can be inserted and moved lengthwise without friction. The keder rail has areas where it can be inserted, for example, for tensioning purposes. The keder and keder rail thus allow the tarpaulin to be tensioned across its entire surface, perpendicular to the edge line.

[0019] According to at least one embodiment, the application element, the guide element is detachably fixed to the tree trunk and / or the flat base element is formed from a bendable and / or stretchable material, such as plastic.

[0020] A “flexible” material is understood to mean that it can be inserted or stretched around or into any corners, edges, curves or depressions without being destroyed.

[0021] For the purposes of the invention, an “extensible” material is understood to mean a material which can be extended non-destructively to a certain extent in the length or thickness direction of the base element and preferably returns non-destructively to its original state after the mechanical force on the base element is released.

[0022] According to at least one embodiment, the guide element is fastened to the contact element by means of screws, bolts, rivets, adhesives or the like.

[0023] According to at least one embodiment, the reinforcing element is designed in the form of an elongated strut, for example a metal strut.

[0024] A strut is understood to be an elongated strut element, for example, a rod-shaped or flat strut element. The strut element may have a round, rectangular, or other cross-section, but the strut element has a negligible thickness perpendicular to the longitudinal direction, i.e., the main extension direction of the plane.

[0025] Preferably, the thickness of such a strut element is at most ten percent of the length dimension of the strut.

[0026] This makes it possible for the bracing element to be individually adapted to the corresponding size and surface contours of the diversion barrier tree trunk protection device in a particularly simple and preferably trouble-free manner.

[0027] The strut element presented here can therefore span the base element, which can in particular be designed in the form of a tarpaulin, in at least one direction, wherein in a direction preferably perpendicular to the strut extension direction, the base element is free of such a reinforcing effect and can therefore be laid around the tree trunk in such a direction.

[0028] According to at least one embodiment, the present invention is free of a flat tarpaulin along which tree trunks and / or undergrowth can be guided.

[0029] According to at least one embodiment, the reinforcing element can be applied together with the base element in the vertical direction, i.e. substantially parallel to the tree trunk growth direction, and / or substantially perpendicular to the tree trunk growth direction.

[0030] According to at least one embodiment, at least the guide element is formed with an abrasion-resistant and / or low-friction material, for example a steel sheet.

[0031] According to at least one embodiment, the reinforcing element is sewn into the base element at least in places.

[0032] "Sewing in place" of the reinforcing element means that the reinforcing element extends circumferentially around the base element, at least partially on freely selectable sides, for example, however, in a direction perpendicular to the main direction of extension of the reinforcing element. For this purpose, the base element can have guide chambers that are formed at least partially, but for example completely, by the base element, so that the reinforcing element can be inserted into these guide chambers, at least partially, but preferably completely, so that the reinforcing element spans the base element in this insertion direction.

[0033] According to the invention, the guide element together with the landing element are designed in the form of a guardrail and / or protective barrier, wherein a post of the guardrail is formed by the landing element.

[0034] According to at least one embodiment, the reinforcing element is glued, riveted, punched and / or screwed onto the base element at least in places.

[0035] Preferably, however, the reinforcing element is removable from the base element, more preferably detachable from the reinforcing element in a non-destructive manner.

[0036] According to at least one embodiment, it can be applied to the tree trunk without touching a ground from which the tree trunk grows.

[0037] According to at least one embodiment, the reinforcing element is passed through at least one eyelet of the base element.

[0038] The eyelet can be an element in the form of a plastic and / or metal object having at least one hole through which the reinforcement element is passed. The eyelet can be interwoven with the flat base element; for example, the eyelet forms a one-piece element together with the flat remainder of the base element. The eyelet is therefore connected to the rest of the flat base element in such a way, preferably inseparably, that there is neither a gap nor an interruption between the eyelet and the rest of the base element. In such a case, the eyelet is therefore not attached to the rest of the base element by means of a specially designed connecting element (e.g., a screw or other connecting element).

[0039] Alternatively or additionally, however, the eyelet may be attached to the rest of the base element by means of a connecting element, for example a seam connection, an adhesive connection, screws, rivets or another connecting element, but preferably in a detachable manner.

[0040] According to at least one embodiment, a non-stick layer is applied at least partially to an inner surface and / or an outer surface of the base element. The inner surface of the base element is a surface that is designed and intended to be applied to the outer surface of the tree trunk, wherein an outer surface is the surface that is visible from the outside, preferably completely, and forms a surface facing away from the tree trunk.

[0041] The non-stick layer, if applied to the inner surface, can prevent mechanical damage to the tree trunk bark; if applied to the outer surface, passing tree trunks can slide particularly easily along and past the base element.

[0042] In the following, the invention described here is described in more detail with reference to the figures and the associated description.

[0043] In the figures, identical or similarly functioning components are provided with different reference symbols, however, individual components in the drawings described below may be shown exaggeratedly large.

[0044] The Fig. 1 shows a diversion barrier tree trunk protection device 100 for protecting a tree trunk B1, which comprises at least one diversion barrier which can be guided around a circumference in the radial direction around a tree trunk B1 and at least one holding element for releasably fixing the diversion barrier to the tree trunk B1, which is characterized in that the holding element is designed such that the diversion barrier can be pressed, in particular solely, against the tree trunk B1 by the holding element, so that tree trunks and / or undergrowth can be guided past the tree trunk B1 along the diversion barrier, in particular wherein the diversion barrier or at least a part thereof is inflexible.

[0045] The diversion barrier has at least one guide element which can be applied to the tree trunk B1 by means of at least one application element, wherein the application element releasably fixes the guide element to the tree trunk B1.

[0046] It can also be seen that the guide element is fastened to the mooring element by means of screws, bolts, rivets or the like, which is free of a flat tarpaulin along which tree trunks and / or undergrowth can be guided.

[0047] At least the guide element is formed with an abrasion-resistant and / or low-friction material, for example a metal sheet, and at least the guide element together with the contact element are designed in the form of a guardrail and / or crash barrier, wherein a post of the guardrail is formed by the contact element.

[0048] In the case of the diversion barrier tree trunk protection device 100, the diversion barrier can be applied to the tree trunk B1 without touching a ground from which the tree trunk B1 grows.

[0049] From the Fig.2 shows a diversion barrier tree trunk protection device 100 for protecting a tree trunk B1. The diversion barrier tree trunk protection device 100 comprises a flat base element 1, which is designed in the form of a tarpaulin and which is placed around the tree trunk B1, preferably flush.

[0050] In addition, a plurality of reinforcing elements 2, which are variously designed in the form of metal or plastic, are depicted, wherein these metal struts are sewn or otherwise connected to the base element 1 in a direction perpendicular to the main extension direction of the reinforcing elements 2, i.e., in a vertical direction V, which is substantially parallel to the tree trunk growth direction. The reinforcing element 2 therefore reinforces the base element 1 in its planar configuration along the vertical direction V, so that it can be laid, preferably flush, around the tree trunk B1.

[0051] In this respect, the reinforcing element 2 is designed in such a way that, together with the flat base element 1, it adapts and / or is adaptable, at least partially, to the outer shape of the tree trunk B1.

[0052] The tree protection cover protects the tree with the help of an abrasion-resistant and low-friction tarpaulin that is attached to the tree near the ground with two straps. The tarpaulin is cut so that it widens towards the bottom and can therefore also cover the base of the tree. Several spring steel bands are sewn into the tarpaulin in a vertical direction V. These bands extend to the lower end of the tarpaulin and are straight when not under load. When the tree protection cover is attached to the tree, the spring steel bands adapt to the surface of the tree trunk or the base of the roots. As the tree diameter widens, particularly near the base of the roots, the spring steel bands bend. The resulting force presses the tarpaulin onto the base of the roots and thus protects the tree protection cover from being displaced or turned upside down by a passing tree trunk B1.This allows individual trees to be temporarily protected from abrasion and bark damage in the ground trunk area during logging operations. Due to its light weight and ease of handling, the tree protection cover is significantly more convenient to use than comparable, solid solutions made of wood or metal. Simple installation using two straps also minimizes the time required to secure the tree protection cover.

[0053] Furthermore, it can be seen that fastening elements 3 in the form of tensioning belts are stretched from the outside around the base element 1, as well as the reinforcing elements 2, in order to create a non-slip connection between the base element 1 and the outer surface 21 of the tree trunk B1.

[0054] It can also be seen that an outer surface 21 of the base element 1 is covered, at least in places, with a non-stick layer 20. Alternatively, however, the inner surface 21 could also be covered with a corresponding non-stick layer 20.

[0055] In the sense of the invention, a non-stick layer 20 can be understood as a coating of the base element 1 to which, in particular, tree trunks no longer stick or hardly stick.

[0056] However, the invention is not limited to the embodiment shown above, but encompasses any possible embodiment which falls under claim 1.
