FASTENING DEVICE FOR A HIGH ORIENTED WATER CONNECTION

The invention relates to a device for an above-ground water connection comprising a water supply with a water inlet and a water outlet.

For aboveground water connections, for example, to subsequently install a faucet and / or a water plug above ground, solutions are usually created individually from fittings and / or pipe locations. There are various solutions to realize attachment to vertical surfaces, horizontal surfaces and / or in a loose ground, such as a bed or a lawn.

To attach a water connection to a loose surface, so-called spikes are known, through which the water connection is anchored in the ground. Known spikes usually have a cross-shaped cross-section, with soil residues hanging easily in the corners so that cleaning such spikes after removal from the soil is cumbersome.

It is an object of the invention to provide a device for an above-ground water connection through which a water connection above ground can be laid quickly and easily. It is a further object of the invention to provide a Erdspike for anchoring a water connection element in a loose ground.

This object is achieved by a device for an above-ground water connection comprising a water guide with a water inlet and a water outlet and a base body with at least one attachment structure, wherein on the base body a first attachment structure for attachment of a ground spike and / or a second attachment structure for attachment of the device a surface is provided.

As a water guide is referred to in the context of the invention, a channel structure or the like.

The main body preferably has a contact surface, which rests on the attachment to a flat surface on this. The contact surface is in one embodiment even when mounted in a soil on the ground and thus prevents further penetration of the device into the soil.

The attachment structures can be designed appropriately depending on the use of the device. In this case, in particular by means of the first attachment structure, a ground spike can be permanently or detachably connected to the main body and thus to the water supply. In contrast, the second attachment structure serves to lay the water connection on a vertical surface, such as a Wall, a garden fence or the like, or a horizontal surface, such as a floor, a balcony or the like. The device can be connected to the surface permanently, for example by welding or gluing, or detachably, for example by latching, screwing or the like. A connection is' preferably such that a substantially smooth contact surface of the body is placed on the surface. Attachment structures for the earth spike may also be provided in the area of the contact surface, wherein the attachment structures preferably do not protrude from the contact surface in order to selectively connect the base body to a ground spike or to attach it to a flat surface when the earth spike is detached from the base body.

In one embodiment of the invention, the main body extends transversely to an axis of a mounted and / or mounted earth spike, in particular at an angle of approximately 90 °. The body serves to handle the device when introducing the earth spike in the ground.

In a further embodiment of the invention, a ground spike is attached to the base body, which has a free end formed as an obliquely cut tube. The earth spike has a shape similar to the shape of an injection needle. Such a shape minimizes friction when penetrating the ground. The tubular design allows easy cleaning, especially when the oblique gate extends substantially over the entire length of the earth spike.

In a further development of the invention, the base body extends in a first direction transverse to the axis of the earth spike, in particular at an angle of approximately 90 °. Preferably, the base body extends from one side of the earth spike, which is an oblique - A -

section of the earth spike is substantially opposite and / or from a side on which the gate is provided. By an extension of the body in the first, the gate opposite direction is a force application to the body for introducing the ground spike in a soil particularly favorable. Counter forces of the soil during penetration act more on a concave inner surface, than on a convex outer surface of the earth spike and can be better absorbed on the body. The base body and / or a further handling structure may additionally or alternatively extend from the axis of the earth spike transverse to the axis in a second direction, which lies in extension of the first direction and / or transversely thereto.

In an advantageous embodiment, the tube has a round, in particular an oval, a circular or an elliptical cross section. The oval cross-section ensures a high flexural rigidity and a robust appearance. The tube preferably has a smooth surface, without grooves, edges and the like. This prevents dirt from adhering to the pipe. The distance of the gate from an end of the earth spike associated with the base body is advantageously smaller than the diameter of the pipe at a round cross section or smaller than the larger diameter at an oval or elliptical cross section. In an embodiment with an elliptical and / or oval cross-section, the cutting edge of the gate preferably extends such that a line of intersection of a cross-sectional area with the cutting plane is substantially parallel to the direction of the smaller diameter. In other words, the sectional area is inclined about an axis of the direction of the smaller diameter with respect to the axis of the earth spike. The earth spike is preferably connected to the base body such that the base body extends in a direction parallel to the direction of the larger diameter. In yet another embodiment, the ground spike is releasably attachable to the base body, in particular latched to the base body by means of latching and / or snap structures. The main body and the earth spike may have mutually complementary latching structures or threads. The detachable connection can be further realized and / or strengthened by means of releasable securing elements such as screws and the like. By loosening the earth spike from the main body, a good cleaning of the ground spike is possible. In addition, the base body after loosening the earth spike at another location, for example, be attached to a surface.

In a further embodiment of the invention, the base body is at least partially designed as a tread. The tread preferably has sufficient strength for a foot operation. The base body preferably extends transversely to an axis of the earth spike, in particular substantially perpendicular to the axis of the earth spike. On the main body ribs or the like are preferably provided for suitability as a tread surface, which prevent slipping in a foot operation.

In one embodiment of the invention, the second fastening structure comprises at least one screw hole and / or a latching structure. The second attachment structure for attachment to a surface is preferably selected such that the base body is not or at least only slightly weakened.

In a further embodiment of the invention, the water guide is designed such that the water outlet with the water inlet forms an angle, in particular an angle of approximately 90 °. The water guide is preferably designed L-shaped. This is a good attachment of hoses, water connection elements, but also of other devices, such as impulse sprinklers, possible. The water guide and the base body can be realized as a common component, in particular as an injection-molded component. In this case, the water supply can partially run in the main body. In other embodiments, the water guide and the base body are formed as separate components, which are permanently or detachably connected to each other, in particular locked and / or glued.

In yet another embodiment of the invention, the water outlet has an external thread with a first thread dimension, in particular a male thread, and an internal thread with a second thread dimension, in particular a Vz "internal thread, which is smaller than the first thread. As a result, connection parts of various types can be connected to the device as needed. For example, it is conceivable to connect either a faucet to the internal thread or a tap piece to the external thread.

In an advantageous embodiment, the water inlet has an external thread and / or a nipple for a hose connection. A hose can thus be advantageously attached to the water inlet.

The object is further achieved by a Erdspike for attaching an above-ground water connection to a loose ground, the Erdspike has a trained as an obliquely cut pipe free end. The earth spike has a shape similar to an injection needle. Such a shape minimizes friction when penetrating the ground. The tubular design allows for easy cleaning, especially when the oblique gate is formed essentially over the entire length of the ground spike. stretches. The tube has, for example, a round, oval or elliptical cross section.

In an advantageous embodiment of the earth spike this is arranged on a device comprising a water guide with a water inlet and a water outlet and a base body, wherein the base body is designed as a tread. The arrangement of the earth spike on the device can be permanent or detachable. The earth spike may be integrally formed with parts of the device. In other embodiments, the ground spike is made separately and connectable to the device, in particular to the base body, by means of snap-fit and / or latching structures.
