    Description: The invention relates to a covering device for a bed, comprising at least two arched supports each straddling a tendon and arranged at a distance substantially parallel to each other, and a flexible cover element for spanning a surface resulting from the tendon and the distance results, wherein the cover element is in an operative condition of the cover on top of the supports. In addition, the invention relates to a rectangular plant trough with such a covering device.
    Covering for covering of beds are used to protect plants in particular from the weather. By taking advantage of the greenhouse effect under a closed cover, they can also be used to promote the growth of the plants. Such a covering device discloses CH 387 368 and GB 847811. They offer the possibility of changing the covered area for easy access to the plants, for example for watering, fertilizing, or for temperature regulation. However, the adjustment mechanisms are often expensive to produce, unwieldy to operate or structurally complex and therefore expensive.
    The invention is therefore an object of the invention to improve a cover for a bed in the sense of ease of manufacture and handling.
    The object is achieved by a covering device with the features specified in claim 1. According to the invention, the covering device mentioned at the outset is further developed by an adjusting device which is arranged exclusively on the cover element and which serves to vary the surface covered by the cover element. The bed can z. B. a Blu¬men- or herbal bed or an area with grass seedlings. The cover device may lie on a floor surface or other substantially flat support surface, e.g. On an edge of an artificial raised bed. The supports are preferably longitudinally parallel to each other. They can be made of wood and / or plastic and / or metal, for. As impregnated wood, galvanized steel or aluminum. In a list of Abdeckvor¬richtung outdoor is a corrosion and weather resistant design of the supports vor¬teilhaft. Under the tendon, which span the arcuate supports, a Verbindungs¬ distance of the two bases of the support is understood. Describing the support a Halbkreisbo¬gen, the chord coincides with the diameter of the semicircular arc. Along the tendon of an arcuate column, a brace can connect and stabilize the feet of the column.
    The flexible cover element may in principle be made of any material, e.g. a translucent, tear-resistant and UV-light-resistant plastic tarpaulin, a reed mat or a textile membrane. Preferably, it is made in one piece, which facilitates the operation of the Abdeckdeckvorrichtung. The area covered by the cover element may be larger than the product of the distance and the chord such that a roof-like overhang is formed on one or more sides of the cover device.
    The adjusting device can be arranged loosely, detachably or fixedly at any desired point of the cover element. In any case, it is not in a constructive or mechanical connection to the supports. It can lock the cover element in at least two positions, at least one open and one closed and one or more intermediate positions, so that it can take the positions permanently. For this purpose, the Verstelleinrich¬tung detachable locking elements, z. Example, a zipper, a clip or push-button system, straps, straps, or comprise a locking unit and festle¬ the cover, lash or lock. The adjustment may include at least partially winding the flexible cover member.
    The invention thus turns away from the fact that the adjusting device is arranged on the supports and on the cover element. Rather, it pursues the principle that the cover element is largely loose on the supports. The adjusting device according to the invention thus offers the advantage of easy operation. In addition, it can also be divided easily and inexpensively.
    So that the cover element does not sag, it can rest on supports at close intervals. According to a preferred embodiment of the invention, clamping elements for tensioning the cover element are arranged on the cover element. The clamping elements can tension the cover element by means of a tensile force which is introduced at fixed points into the cover element and / or by means of a tensile force which arises by weight. The tension members may tension the cover member across the gap and / or over the chord or along a bearing surface of the cover member on the supports. Preferably, they perform both functions. You can z. B. as hooks, clips or (elastic) Spanngurtausgebildet, which are fastened to the cover element and the cover element in some sections hook on the supports and thus tension it. The tensioning elements may comprise weights on the edges of the cover element, which pull the cover element transversely and longitudinally along the support curvatures around the floor and thereby tighten it. They may also be formed as sewn-in stiffening folds or ribs on the cover element itself or as sewn-in, glued-on or otherwise fastened rods, strips or slats. They offer the advantage that they prevent sagging of the cover element and thus ensure, on the one hand, the plants inside the bug shooter and, on the other hand, easy handling of the cover device.
    The cover element may rest loosely on the supports and remain in a position on the supports only due to its weight and / or a balance of downward weight forces, without slipping off. Additionally or as a precaution, it may be mounted at least partially permanently or detachably on the supports. Preference, the erfin¬dungsgemäße cover device comprises at least one fastening element for fixing the De¬ckelements on the tops of the columns. The fastening element can be arranged on the cover element or on the supports. In principle, it can hold the cover element at any desired position of the supports, but preferably at vertices of the supports. Then, by utilizing gravity, the flexible cover element can hang down on both sides of each support arch and be tightened by its weight. An arrangement of the fastening element at the vertices of the supports also ensures a particularly good accessibility of the bed for the operator by two equal openings on both sides of the cover.
    The fastener may be formed as an adhesive, for. B. as a rubberized surface, and thus prevent slipping of the cover member of the supports. Preferably, it comprises a mechanical connection which prevents both slippage in the mounting plane and lifting of the cover element substantially vertically to the mounting plane, e.g. B. by a gust of wind, protects. The mechanical connection can e.g. be designed as a clamping, nail or screw connection. The fastener prevents slippage of the cover member from the tops of the legs regardless of how far the cover member is attached e.g. B. is uncovered and spans the bed. It also allows loosely resting the cover element on the supports, so that an operator can take off sections of the cover element comfortably from the supports and operate.
    In principle, the adjusting device can vary the cover element at least between a completely covering position and a completely uncovering position. According to another preferred embodiment, the adjusting device comprises holding elements for a stepwise change of the surface spanned by the cover element, which at certain distances from each other Cover element are attached. After lifting a portion of the cover member from the tops of the supports, e.g. As a reduction of the spanned area, the section can be stored on the rest of the cover element. The retaining elements are adapted to hold the section in this condition by preferably locking them together and preventing the cover element from slipping along the arcuate supports at least. Advantageously, they can afford this for differently sized sections, ie in several stages. A gradual or graduated adjustment means that between a completely covered by the cover element
    Beetfläche and a completely uncovered surface is at least one position in which the Beetfläche is partially (un) covered. The spacings of the holding elements define possible positions of a covering of the bed surface. For optical reasons, the holding elements can preferably be arranged uniformly and / or symmetrically on the cover element. As holding elements can z. As hooks, clamps or a hook and loop fastener serve, holding can for example take place in the form of a hooking, Anklammerns, wedging or clipping. The retaining elements according to the invention offer the advantage of easy handling of the covering device.
    Preferably, the holding elements extend over the longitudinal extent of the cover element and thus at least over the distance of the supports. The support members may also be formed in a simple embodiment as strips, slats or rods with a rectangular cross-section. Long sides of the holding elements can extend along the distance of the supports, their end sides then run substantially parallel to the chord of the supports. To hold the cover element, they can in principle be mounted on any points of the cover element or fastened to it.
    With a rectangular cross-section of the holding elements, they provide on a broad side a contact surface, with which they lie in operation on an upper side of the cover member and possibly are attached thereto. A narrow side can serve as a holding surface on which another Hal¬teelement can rest with its narrow side. An attachment and fastening element arranged at the vertex of the support arches has two substantially vertically standing side surfaces as such retaining surfaces. On both side surfaces, another holding element can be applied with its narrow holding surface, so that a downward weight force of the cover element and the optionally further holding elements arranged thereon is accommodated. According to this principle, each further retaining element can be locked at each uppermost Hal¬teelement. Since in a fastening of the cover element to the supports unglei¬che tensile forces are absorbed on two sides of the cover member and do not lead to slipping of the support arches, any retaining element can be locked to an overlying retaining element. The adjusting device can therefore also consist exclusively of the retaining elements.
    The holding elements according to the invention offer the advantage that they hold the cover element over the entire distance away. Preferably, the holding elements function equally as clamping elements. It proves to be advantageous if the cover element is attached thereto in a suitable number of connection points on the holding elements and thus is supported by the holding elements.
    According to a preferred embodiment, the covering device comprises slats with a rectangular cross-section, which at the same time serve as fastening elements and as clamping elements and further such slats serving as clamping elements, holding elements and adjusting means. The slats can be made of wood and / or metal and / or plastic , When a lattean vertex of the support arches is mounted, with an even number of additional slats a visually appealing, uniform and / or symmetrical distribution of the slats on the cover element can be achieved. For example, the cover element may carry three, five, or seven battens. At those edges of the cover element which extend parallel to the distance, d. H. run in the operating state near the ground, thicker or doubled slats may be mounted. Due to their higher weight they achieve a higher pulling force, so that the cover element always remains taut and offers better wind stability. The slats thus act as clamping elements not only over the distance, but also over the distance along the course of the support arches. Because they compensate for a possibly low inherent weight of the cover element and increase a tensile force for tensioning the cover element. The slats offer the advantage of a cost effective and effective constructive solution, while at the same time fulfilling three essential functions. They allow a cost-effective production and give the cover device according to the invention a particularly simple and convenient operation.
    The covering device may in principle have supports made of aluminum, which offer Gegewichtsvorteile and high corrosion resistance. Preferably, it includes ferro-magnetic supports, z. B. steel, and uses magnetic forces for the adjustment. The magnets can be placed on the cover element from the outside and act on the top of each support. The magnets can z. B. be designed as individual magnets or in the form of a flexible magnetic strip. You can permanently connected to the cover element, for example, be welded or sewn. The cover element can thus be lifted by the operator, wound and locked in any position on the supports. This alternative adjusting device offers the advantage of infinitely variable variation of the area spanned by the cover element and thus of particularly flexible setting of access to the bed. The magnets can also serve as fasteners, as clamping elements and as holding elements.
    According to a further preferred embodiment according to the cover device comprises on Stützfußfüßen fastening means for their attachment to the bed. The column feet may be formed as spikes or in the manner of herring to be anchored directly in the ground. Alternatively or additionally, they can be designed to receive fixing means and, for example, be provided with apertures, bores, perforated plates and optionally with angle plates for receiving screws, nails or the like. The attachment of the cover device according to the invention offers the advantage of a convenient and secure anchoring of the cover device, eg. B. against wind load.
    Preferably, the cover comprises covering units for frontal Befesti¬gung on the supports. The cover units can, for. B. circular segment and the Bogen¬verlauf the supports adapted. A cover unit may consist of a covered frame or of a frame provided with a rigid and possibly translucent element, e.g. B. a plexiglass, is occupied. Alternatively, a cover unit itself may consist of the rigid element. The cover unit may be fixedly or detachably mounted to the supports, e.g. by a screw connection, a magnetic connection or a clip system. It proves to be advantageous in that it makes it possible to close off the interior of the covering device or the weatherproof cover.
    The invention also relates to a plant trough with a covering device as described above. The plant trough may be rectangular or square and includes at least one top opening for receiving a bed. Its frame may be suitable as a support surface for placing and / or fixing the Abdeckvorrich¬ invention. The plant trough may for example be made of wood, metal, plastic, natural stone or ceramic and have any size.
    The principle of the invention will be explained in more detail below with reference to a drawing beispielshalbernoch. 1 shows a schematic view of an end face of a plant trough with a covering device in a first position, [0022] FIG. 2 shows a view according to FIG. 1 in a second position, [0023] FIG Fig. 3: a schematic view of a longitudinal side of a plant trough with a cover device according to Fig. 1 in a third position, Fig. 1 shows on a horizontal footprint 1 a cuboid trough 3 from a narrow side, such as a plant trough or raised bed Use finds. On a support surface 7 of an edge 5, which surrounds a bed surface (not shown) of the trough 3 rectangular, is a cover 9 as a cover. The cover 9 covers a bed surface with one comprising two support arches 10 as supports, each spanning a chord a and thus spanning a narrow side of the edge 5, at a distance b (see Fig. 3) corresponding to a long side of the edge 5 and parallel to each other are arranged. The cover 9 comprises a support sheet 11 (Figure 3) having identical dimensions as the outer sheets 10 have. He stands between them and spans the bed in one
    Route a. In contrast to the support arc 11, the support sheets 10 each have a base 12, d. H. a trained as a tendon bracing between two ends of the bow. The base 12 is flat on the support surface 7. The support arches 10, 11 are made of galvanized steel.
    On the support arches 10, 11 is a rectangular tarpaulin 20 as a cover element, which may be, for example, a translucent, reinforced with a welded textile mesh plastic cover. An elongated mounting bar 30 with a rectangular cross-section serves as Befestigungs¬element the tarpaulin 20. The bar 30 is located on a ridge of the cover 9 and at apex 14 of the support arches 10, 11 on this and is with screws 26 as fasteners on the sheets 10, 11 attached. The screws 26 also penetrate the tarpaulin 20 and fix it therewith. Since the tarpaulin 20 is clamped between the mounting bar 30 and the top surfaces 16 of the support sheets 10, 11, it is held taut throughout the distance b. At a top or outside 24 of the tarpaulin 20 are at intervals to each other Halt¬elatten 40, 41,42 mounted by means of a screw connection. The figure shows on both sides A, B of the mounting bar 30, a lower Haltelatte 40, in each case an overlying middle Haltaltatte 41 and in each case one between the Haltelatte 41 and the mounting bar 30 liegen¬de upper Haltelatte 42. They extend parallel to the mounting bar 30, Also have a rectangular cross section and have an identical length that corresponds to a side length of the tarp 20. The respective outer retaining slats 40 are made in duplicate by two identical slat segments pinching an end piece of the tarpaulin 20. The slats 40, 41, 42 both longitudinally and transversely of the tarpaulin 20 along the surface 16 of the sheets 10, 11, as tensioning elements against sagging of the tarpaulin 20: they reinforce the tarpaulin 20 longitudinally and set it over its narrow side 23 away by their Ge weighting under a tensile stress. The slats 40, 41, 42 thus prevent longitudinal and transverse sagging of the flexible tarpaulin 20, even regardless of whether and how far it is open, as shown in FIG.
    Fig. 2 first demonstrates the additional function of the slats 40, 41, 42 as Verstell¬einrichtung: the tarpaulin 20 is partially uncovered, on the right side B, a larger opening than on the left side A. A user can on the support arches 10, 11-lying tarpaulin 20 stepwise, namely at the distance of the slats 40, 41, 42 discover and set by means of the slats 30, 40, 41, 42 in defined positions. For uncovering the panel 20 or for reducing the amount of bed area covered by the tarpaulin 20, the user first raises part of the tarpaulin 20 together with the lower support bat 40. He then turns both 180 ° that a mating surface 44 of the lower Haltelatte 40 z. B. abuts a holding surface 43 of the retaining batten 41. The holding surface 43 is at an angle α of about 30 ° to the footprint 1. When the user the mating surface 44 is flat on the support surface 43, the bar 40 is tilted by the angle α to the right on the Haltelatte 41. The inclination of the retaining mat 41st thus secures the lower Haltelatte 40 against a gravitational slippage. For example, against conventional wind forces, the weight of the retaining batten 40 acts itself.
    At the upper Haltelatte 42 are similar conditions here, here by the flatter running of the support arches 10, 11 with an even greater inclination of the support surface 45 by an angle ß of about 60 ° to the footprint 1. The weight of the down-pulling lath 41tracts the Plan 20 below the slats 40, 42. Finally, the support slat 40 may also be applied to the attachment slat 30. If the holding battens 40, 41, 42 of both sides A, B of the cover 9 are pulled together on the fastening bar 30 in order to expose the bed surface to a large extent, they can be fastened to the supporting bows 10, 11 with straps (not illustrated), at the ridge of the cover 9 are tied into a package.
    Fig. 3 shows a corresponding view of a long side of the trough 3 and the cover 9. The tarpaulin 20 is largely removed from the surfaces 16 of the support arches 10, 11. It is at apexes 14 of the outer support arches 10 and Its anchoring to the sheets 10, 11 by means of the mounting bar 30 ensures that it does not slip off the position at the apexes 14. The underside of the tarpaulin 20 ver¬ covers the slats 30, 40, 41, 42. A user can the wound tarpaulin 20 z. B. by means of a belt to prevent self-development. The user gains through the entstan¬denen openings 50, 51 a comfortable access to the bed in the trough 3, the insbesondre of disturbing cross struts.
    The tarpaulin 20 is longer than the distance b and is at two ends like a roof over the support arches 10, 11 over. The slats 30, 40, 41, 42 carry the tarpaulin 20 over its entire length, thus preventing its sagging. The support arches 10, 11 have in lower Berei¬chen support legs 25, which are anchored by means of retaining screws 26 as a fastening means on the Auflageflä¬che 7. The cover 9 is thus stably connected to the trough 3.
    The outer support arches 10 each have a removable front side cover 19 vorgeblen¬det at their facing away from the openings 50, 51 Au¬ßenseiten 17. The front cover 19 consists of a frame 18 in the form of a Kreisseg¬ments, which is adapted to the shape of the corresponding support sheet 10. Detachable retainers 22 secure the frame 18 to the outsides 17 of the support arches 10. Above the frame 18 is tensioned a tarpaulin 21 for covering a frame opening. The Stirnseiten¬abdeckungen 19 cover the end faces of the support arches 10 and allow in cooperation with the tarpaulin 20 a closed state of the cover 9. It protects the Beetwirkungsvoll from the weather.
    Since the covering device described above in detail is an embodiment, it can be modified in a customary manner by a person skilled in the art to a large extent without departing from the scope of the invention. In particular, the concrete configurations of the adjusting device can also take place in a different form from those described here, for example with additional securing by Velcro, or the like. Also, the support arches can be configured in a different form, for example in a flat arch or polygonal, if this is desirable for designischen reasons. Further, use of the indefinite article includes " or "a " does not mean that the relevant features can also be present several times.
