Description

technical field

The invention relates to an arrangement for illuminating a lawn boundary.

State of the art

Various types of lawn edging profiles are known from the prior art, which are generally designed as flat ridges that are sunk into the ground at the edge of the lawn. They are intended to give the lawn a permanent, clear and aesthetically attractive border. the DE 20 2009 010 493 U1 discloses, for example, an area boundary consisting essentially of a slab of corrosion-resistant material embedded in a substrate.

In many cases it is desirable to illuminate such a lawn boundary. In particular, along sidewalks, lighting can enable the user to find their way around safely. In addition, a visually appealing, aesthetic appeal can be generated for the viewer.

A profile for delimiting lawns, which also serves as a holder for a light tube as a lighting element, is for example from DE 20 2011 052 470 U1 known.

the WO 2011/119616 A1 describes a ground anchor for lawn edges with a pointed anchoring section and a preferably C-shaped receiving section opposite the anchoring section for receiving a holding element. The holding element has a clamp-like holding section for receiving a light tube. The C-shaped receiving section has a large number of grooves on its outside, while the retaining element has corresponding engagement means, so that the retaining element can be fastened to the receiving section in a latching manner. The orientation of the luminous tube can be adjusted by twisting the holding element relative to the C-shaped receiving section.

However, it has been found that with the lighting of lawn area boundaries known from the prior art, precise adjustment of the illuminated area is in no case possible. In all cases, the delimiting elements are either overexposed, which can blind the user, or the delimiting elements are not illuminated clearly enough.

In the further development of lighting elements for lawn edging, an aesthetically pleasing, precise lighting of the boundary elements of the lawn is therefore a priority.

Presentation of the invention

It is therefore the object of the present invention to provide an arrangement for illuminating a lawn area border that enables aesthetically pleasing, pinpoint lighting of the lawn area bordering elements. This object is achieved according to the invention by the arrangement for illuminating a lawn boundary according to claim 1 and the method for illuminating a lawn boundary according to claim 13 . Further advantageous aspects, details and configurations of the invention result from the dependent claims, the description and the drawings.

The present invention provides an arrangement for illuminating a lawn boundary. The arrangement comprises a height-adjustable lamp tube holder, a lamp tube having a longitudinal axis, the lamp tube having a C-shaped cross section perpendicular to its longitudinal axis, an elongated lamp arranged in the lamp tube and a plate-like lawn area delimiting element having openings. When installed, the lawn area delimiting element is arranged with a lower section in the ground and an upper section of the lawn area delimiting element protrudes from the ground. The lamp tube holder has a ground anchor that can be introduced vertically into the ground and a retaining element that is designed to be movable at least in the vertical direction relative to the ground anchor. The holding element is designed to receive and hold the lamp tube, with the lamp tube being mounted in the holding element such that it can rotate about its longitudinal axis.

The arrangement according to the invention makes it possible to precisely illuminate a lawn area boundary element and in particular its openings. Due to the combination of the adjustability of the holding element in the vertical direction and the rotatability of the illuminant tube, the light emerging from the illuminant tube can be directed precisely onto the openings in the lawn area boundary element. The light penetrates the openings in the lawn area delimitation element, which are designed, for example, as an ornamental pattern in this way glare-free orientation and safety on sidewalks, for example.

In principle, the retaining element can be attached to the ground anchor in any desired manner. Any force-fitting and/or form-fitting attachment is conceivable, such as a press fit of the holding element in a rail-like recess of the ground anchor. However, at least one fastening element is preferably provided, with the fastening element being designed for the fixed but detachable fastening of the holding element to the ground anchor. With the aid of a fastening element that can be reversibly detached and fastened again, it is possible to fasten the holding element to the ground anchor in a desired position in a secure, adjustable and reproducible manner.

According to a preferred embodiment, the at least one fastening element consists of a screw and an associated nut, the ground anchor and holding element having slot-like openings oriented in the vertical direction and the screw penetrating the slot-like openings of the ground anchor and holding element. This embodiment is structurally simple to produce, can be implemented with parts that are available in any quantity and at low cost, and offers a secure, infinitely adjustable and reproducible attachment of the holding element to the ground anchor in a desired position.

The light source is preferably an LED light tube or an LED light strip. This type of illuminant is available in any quantity at low cost. LED strips and tubes are available on the market in a wide variety of lengths and produce light in any desired color. This type of light source is therefore particularly suitable for illuminating a lawn area boundary.

The lamp tube is preferably made of plastic. Plastics known to those skilled in the art have a resistance to the effects of weather that is required for outdoor use. The corresponding illuminant tubes are also inexpensive to produce.

The lawn area boundary element is preferably made of copper, stainless steel, wood or aluminum. The copper material in particular has the additional advantage that the lawn area boundary element acts as a barrier for snails.

According to a particularly preferred embodiment, the holding element has a U-shaped section for receiving and holding the lamp tube. The lamp tube can be inserted particularly easily into a U-shaped section and fixed in a non-positive and/or positive manner with appropriate dimensioning.

A rod-like fixing element that can be introduced vertically into the substrate is particularly preferably provided, with the fixing element encompassing the holding element with its section that protrudes from the substrate in the installed state in such a way that the fixing element spans the open section of the holding element provided for receiving and holding the lamp tube. If the dimensions of the lamp tube and the section of the retaining element intended to accommodate the lamp tube are not so precisely matched to one another that the lamp tube is securely fixed in a clamped and/or friction fit, additional fixing elements can be provided to ensure a secure and permanent arrangement of the Secure the lamp tube in the holding element.

The lawn area delimiting element particularly preferably has barbs for connection to the ground. As a result, the lawn area delimiting element is seated particularly securely in the ground.

Embodiments are also preferred in which the lawn area delimiting element in the installed state is kinked in the edge area of its upper section protruding from the ground in the direction of the lamp tube holder, openings being provided in the kinked area. In this embodiment, the lawn area delimiting element thus has the shape of a preferably right-angled hook in cross section. In this case, the light emitted by the lighting means also penetrates the openings provided in the bent area, as a result of which the lawn area delimiting element is also illuminated upwards, which provides additional orientation and safe walking for a user.

According to a further preferred embodiment, the arrangement has a plurality of lawn area delimiting elements which are adjacent to one another and arranged next to one another and a plurality of lighting means tubes which are adjacent to one another and arranged next to one another. Lawns are typically of an extended size, requiring the lawn edging to be constructed in multiple pieces to remain manageable and easy to manufacture. In the case of extensive lawns, it is advantageous to have several lawn area delimiting elements and several lamp tubes next to one another arranged and form in this way, in principle, arbitrarily extended lawn borders.

According to a further preferred embodiment of the present invention, the several adjacent lawn area delimiting elements arranged next to one another and/or the several adjacent illuminant tubes arranged next to one another are connected to one another by coupling elements. In this way, both the lawn area delimiting elements arranged next to one another and the lamp tubes arranged next to one another are fixed to one another, as a result of which slipping of the individual elements relative to one another can be reliably prevented.

The arrangement particularly preferably serves to delimit a lawn area from an area with unpaved soil, the ground anchor that can be inserted vertically into the subsoil being present in the installed state in the area of unpaved soil in the subsoil. The arrangement according to the present invention has proven to be particularly useful when the arrangement is used to delimit a lawn area from an area with unpaved soil, such as a bed. In this case, the ground anchor, which can be inserted vertically into the subsoil, is present in the installed state in the area of the unpaved soil in the subsoil. In this case, the lawn area delimiting element is illuminated from the area with unpaved soil in the direction of the lawn area and thus illuminates the area of the ground that can be walked on by a user as desired.

It is clear to the person skilled in the art that the steps mentioned do not necessarily have to be carried out in the order mentioned. So it is of course up to the user whether the lawn area delimitation element is inserted into the ground first or the ground anchor. Likewise, the lamp tube can first be arranged in the section of the holding element provided for holding the lamp tube and only subsequently the lamp can be arranged in the lamp tube. Lamps that are already arranged in a lamp tube can often also be obtained from appropriately specialized manufacturers.

Particularly preferably, the rotation of the lamp tube about its longitudinal axis takes place in such a way that the radiation generated by the lamp escapes essentially completely from the lamp tube in the direction of the openings in the lawn area delimiting element. In this case, the light penetrates the openings in the lawn area delimiting element, which are designed, for example, as an ornamental pattern, and in this way offers glare-free orientation and safety, for example, on footpaths or lawns. At the same time, an aesthetically appealing impression is achieved through the freely configurable ornamental pattern.

The lawn area delimiting element is particularly preferably introduced into the subsoil in such a way that it serves to delimit a lawn area from an area with unpaved soil. The ground anchor, which can be inserted vertically into the subsoil, is inserted into the subsoil in the area of the unpaved soil. The arrangement according to the present invention has has been found to be particularly useful when the arrangement is used to demarcate a lawn from an area of unpaved soil, such as a bed. In this case, the lawn area delimiting element is illuminated from the area with unpaved soil in the direction of the lawn area and thus illuminates the area of the ground that can be walked on by a user as desired.
