Description

MOUNTING SYSTEM WITH FLOOR ANCHOR AND

MULTIFUNCTIONAL ELECTRIC SHIFT

TECHNICAL FIELD OF THE INVENTION The invention relates to a mounting system with a ground dowel and a

Insertion aid, a ground anchor and a multifunctional insertion aid.

BACKGROUND OF THE INVENTION

Ground dowels have long been known in a variety of forms, e.g. from DE 200 00 182 U1. They serve both for temporary support of posts and masts in the ground, such as e.g. the posts of clothes dryers, umbrellas and the like, which are removed again after use from the ground anchor, while the ground anchor itself remains in the ground, as well as for permanent attachment e.g. of fence posts, lights and smaller wind turbines and solar panels.

If objects, such as Parasols and clothes dryers, to be held only temporarily, is usually desired that the ground dowel no

Stumbling block forms when no object is received in it. In such cases, it is therefore important to turn the ground anchor as completely as possible into the ground. There have already been a variety of types of floor dowels for

proposed different soils, each of which should accomplish the task, on the one hand easily be screwed into the ground, but on the other hand in the

screwed state sufficiently anchored in the respective soil, so that an adjusted in the ground dowel object, e.g. a parasol or a clothes dryer, where especially in wind quite considerable forces can occur, can be held securely.

While certain special soil anchors, which are targeted to a specific type of soil, this requirement in a more or less satisfactory manner meet the requirement that most commercially available Universal soil dowels, which are suitable for typical soil compositions in German gardens, the problem that they can not be completely screwed into the ground.

Universal soil dowels typically have a tip, a threaded portion, a conical compression portion and a cylindrical holding portion, wherein the core of the threaded portion is cylindrical in some ground dowels, conical in others more or less.

DISCLOSURE OF THE INVENTION

The invention is based on the object, a ground dowel and a

Specify mounting system with such a ground anchor, in which the ground anchor is improved in terms of its Eindrehbarkeitseigenschaften over the known universal floor dowels, without thereby in his

Anchoring properties to be impaired.

The object is achieved by a mounting system with the features of claim 1 and a ground anchor with the features of claim 2. The independent claim 15 relates to a multi-functional insertion aid for an inventive mounting system.

The invention is based on the surprising finding that by providing a second threaded portion, which is seen in the screwing after the first compression section, a better Eindrehverhalten can be achieved than with ground dowels with only one threaded portion, the Eindrehverhalten both against ground dowels in which the threaded portion has a cylindrical core, as well as against soil dowels, in which the threaded portion has a conical core is improved.

Further details and advantages of the invention will become apparent from the

following, purely exemplary and non-limiting description of embodiments in conjunction with the drawings. BRIEF DESCRIPTION OF THE DRAWING shows a side view of a first embodiment of a ground anchor according to the invention. shows a highly schematic side view of a multifunctional insertion aid according to the invention. shows a highly schematic side view of a second embodiment of a ground anchor according to the invention. shows a highly schematic side view of a third

Embodiment of a ground anchor according to the invention.

DESCRIPTION OF PREFERRED EMBODIMENTS

FIG. 1 shows a ground dowel designated in its entirety by 10, in which a first threaded section 14, which opens into a first conical compression section 16, adjoins a conical tip section 12. The first conical compression section 16 is followed by a second

Thread portion 18, which opens into a second conical compression portion 20. The second compression section 20 is followed by a so-called.

Holding portion 22 which serves to receive an item to be held by means of the ground dowel and in the embodiment shown by a cylindrical sleeve 23 is formed. Because many items that

typically fastened by means of a ground dowel, e.g.

Wäschespinnen, have posts with a round cross section, have proven for many applications holding sections with cylindrical sleeves whose

Diameter can be easily adapted by means of subsequently described Reduzierhülsen to different diameters of male objects. However, as also explained below, the holding section can also be designed for receiving objects with other cross-sectional shapes, in particular polygonal cross-sections such as square. The tip section 12 is partially formed in this embodiment, ie its free end is not hollow, while its transition region to the first threaded portion 14 is hollow. In this area there is a water outlet opening 24, which allows it in the ground dowel penetrated water to drain. It is also possible to form the entire tip section solid and then optionally provide a water outlet opening at the lower end of the first threaded portion.

In the end region of the holding portion 22, two are diametrically opposed

opposite openings 26 are provided which serve to provide a tool for

Turning the bottom anchor, in particular the power transmission section of the insertion aid to be described below to record.

In the end region of the holding portion 22 of the existing in this embodiment of metal ground anchor 10 also a nut 28 is welded for secure mounting of a fastening screw, not shown here, wherein the holding portion 22 is broken in the passage area of the mother, so that through the nut 28th a corresponding screw can be screwed into the holding portion 22 to a set therein

Object, e.g. to secure a parasol or a clothes dryer by clamping. If the ground anchor is made of another suitable material, e.g. Plastic, one or more nuts can take up

Fixing screws must be poured into the holding section. It is also possible to form a Kunststoffbodendübel so that it has receptacles for one or more nuts.

In an advantageous embodiment (not shown) distributed around the circumference, offset in particular by 120 degrees circumferentially, provided three nuts, so that three fastening screws are screwed, which allows a set object as known from Christmas tree stands within certain limits , So that it is advantageously possible, even with a not exactly vertical screwed into the ground soil dowels

To hold objects vertically. With appropriate material thickness of Of course, holding sections 22 can also be cut directly in place of the nuts for receiving one or more fastening screws.

The core 30 of the first threaded portion 14 is formed in this embodiment as well as the core 32 of the second threaded portion 18 each of a cylindrical tube, wherein the outer diameter of the core 30 of the first threaded portion 14 is smaller than the outer diameter of the core 32 of the second threaded portion 18th Both cores 30 and 32 are each with one

Screw 34 and 36 provided, wherein the pitch of the means of

Screw threads formed identical. In the shown

Embodiment, the second helical coil 36 begins above the first compression section 16. However, it can also be provided that at least a short piece of the helical coil 36 overlaps the boundary region between the first compression section and the second threaded portion, which can facilitate screwing the ground anchor in certain floors. Likewise, the tip portion of the ground dowel facing the initial portion of the thread of the first threaded portion 14 forming helix 34 may overlap the boundary between the first threaded portion 14 and the tip portion 12.

Instead of the illustrated cylindrical cores 30 and 32 may or may have one or both of the threaded portions cores with a conical shape, the

Diameter along the ground dowel seen from the top to the

Holding section enlarged. For both cylindrical and conical cores is provided that the largest outer diameter of the core 30 of the first

Thread portion 14 is smaller than the smallest outer diameter of the core 32 second threaded portion 18th

The defined by the outer diameter of the helix 34

Outer diameter of the first threaded portion 14 is smaller than that through the

Outer diameter of the helical coil 36 defined outer diameter of the second threaded portion. In known universal floor dowels with only one threaded section with a cylindrical core and a conical compression section often shows that the dowel can not be completely screwed into the soil, since the forces generated in the first threaded portion are insufficient, the attacking direction of the ground anchor mainly attacking the compression section to overcome counteracting forces. At some point, such a dowel does not penetrate further into the soil, but "rotates through", ie the helical screw on the threaded section loosens the surrounding soil in the manner of a milling cutter, but does not generate the soil dowels deeper into the soil pulling forces.

In known Universal soil dowels with a threaded portion with a conical core, the problem often occurs that they can be very difficult to bring vertically into the soil and / or loosen up the soil during screwing, so that they can be completely submerged in the ground, there but not anchored in the desired way.

In the ground anchor according to the invention facilitates the first threaded portion 14, the core 30 has a relatively small outer diameter, the vertical screwing of the ground anchor in the ground and thus serves as a quasi

Guide. The forces exerted by the first threaded portion 14 during screwing are sufficient to pull the first compression portion 16, which does not yet increase the diameter of the ground anchor to the full diameter of the holding portion 22, into the soil, so that then the helical coil 36 of the second threaded portion 18th can grab. This helical coil 36 offers in

Cross-section seen a larger contact surface than the first helical coil, so that with her greater forces can be generated, which allow the second compression section 20, which brings the diameter of the ground anchor 10 to the full outside diameter of the holding portion 22, into the soil.

The mounting system according to the invention further comprises a driving aid as shown in FIG. 2, in its entirety designated 40 Eindrehhilfe. The

Insertion aid 40 has a lever arm 42 in this embodiment, one end as handle portion 44 and the other end as

Angled power transmission section 46 is formed. The lever arm 42 preferably extends to the free end of the handle portion 44, i. of the

Handle portion does not attach to the lever arm, but rather is obtained by sheathing an end portion of the lever arm 42, e.g. with plastic or

Sponge rubber or a suitable grip band formed.

The lever arm 42 may be formed of a hollow tube, which has the advantage of lower weight compared to known insertion aids made of structural steel. In addition, soil dowels of the type in question are often offered in hardware stores and discounters in the form of complete support systems, i. a packing unit comprises a ground anchor, a Einrehhilfe and optionally described below Reduzierhülsen and a cap, the Eindrehhilfe is usually used only once and then disposed of. The

The insertion aid according to the invention, on the other hand, serves as a multifunctional tool, for which reason the free end of the force transmission section 46, which is inserted through the openings 26 in the ground anchor 10 shown in FIG. 1, is flattened and provided with a notch, so that the

Driving aid also as nail puller, box opener or e.g. can help to remove hubcaps. It typically has lengths in the range of about 400 to 500 mm with a diameter of typically 15 to 20 mm and a tube wall thickness in the range of 1, 5 to 2 mm. The insertion aid can preferably be designed so that they are in the delivery of a

Ground dowel 10 can be completely plugged into these.

The power transmission section 46 may be wholly or at least partially

be forged. While in the known mounting systems the

Eindrehhilfen are usually disposed of after screwing in a ground anchor, the insertion aid according to the invention for the consumer creates an incentive to use them for other work and thus sustainable use of resources. This is also promoted by the fact that a handle portion 44 is provided, which makes the Eindrehhilfe 40 throughout the wertiger. Known driving aids, however, usually only one rod. In the transition region between the angled power transmission portion 46 and the lever arm 42 is a notch or, as shown

Embodiment, a circumferential groove 48 is provided, which serves to at least partially receive the edge of an opening 26 in a ground dowel 10, so as to prevent slippage of Eindahrhilfe.

As already mentioned, the retention system according to the invention can be packed with so-called reducing sleeves, which serve to secure the

Inner diameter of the holding portion 10 as exactly as possible to the

Outer diameter of a male object, e.g. the standpipe of a rotary dryer or a sunshade to adapt, so that then with a single mounting screw a secure and almost positive retention of the object set in the holding section can be achieved. Such reducers may also serve to facilitate e.g. round

Inner cross section of the holding portion to other desired cross-sectional shapes, e.g. square or hexagonal, adapt.

The support system may further comprise a cap, preferably in a signal color such as red or orange, which serves to cover a ground dowel screwed into the ground when not in use, ie when no object is set in the ground dowel, so as to fill the ground dowel with water to prevent.

In a particularly preferred embodiment, the cap is not of circular cylindrical, but of angular shape, with an octagonal shape has proven particularly useful. It has been shown that in the soil

screwed ground anchors on the outside of the holding section quickly attach a crust, so that round caps are difficult or impossible to put on the ground anchors, if their inner diameter to the

Outer diameter of the ground dowel is adjusted. If, on the other hand, round cover caps have such a large diameter that any possible encrustations on the outside of the holding portion are also taken into account, such are

Cover caps loosely on the ground anchor so that they can be lifted off the wind. Touch six and especially octagonal covers naturally the outer circumference of the holding portion only at certain points, so that they can be placed with slight pressure on such ground anchors on the outer periphery in the region of the free end of the holding portion sticks an earth's crust.

FIG. 3 shows a second embodiment of a ground anchor designated in its entirety by 10 ', which differs from that shown in FIG

Bod dowel in particular by the configuration of the tip portion 12 'and the holding portion 22' different.

The holding portion 22 'in this embodiment is for receiving articles of polygonal cross-section, e.g. Rectangular post, as used for fences and the like, formed, in this embodiment in that on a cylindrical portion 23 of the holding portion 22 'is a receiving portion 52 for objects with a polygonal cross section, namely in this embodiment, a U-carrier is attached. Through holes for fixing screws may be provided in the two parallel legs of the U-beam, e.g. to anchor a square post in the U-beam. Advantageously, in the two parallel legs of the carrier, two diametrically opposed openings can be introduced, which serve a tool for screwing the ground anchor,

In particular, the power transmission section of the driving aid to record.

It should be emphasized at this point that, of course, depending on the design of the ground anchor also possible, instead of the cylindrical portion 23 directly

Receiving section 52 for receiving articles with polygonal

Provide cross section at the second displacement portion 20, which then forms the holding portion 22 'accordingly. Instead of the U-beam shown, rectangular profiles or polygonal sleeves, e.g. six- or octagonal sleeves are provided. However, the illustrated embodiment has the great advantage that ground anchors can be inexpensively manufactured in large numbers, which are "standardized" including the cylindrical portion 23, which has an advantageous effect on the unit price. If then a series of

Soil dowels are needed eg for setting a fence with rectangular profiles appropriate receiving sections, eg the U-beam shown, simply attached to the "standard ground dowel", eg welded.

The tip portion 12 'is not completely conical in this embodiment, but has a conical tip 54, to which a cylindrical

Section 56 connects, but whose outer diameter is smaller than the outer diameter of the first threaded portion 14, so between this cylindrical portion 56 and the first threaded portion 14, a conical compression portion 58 is provided. It has been shown that a

thus formed tip portion 12 'advantages in positioning the

Ground anchor has, since the first part of the tip portion 12 ', the tip 54, very easily penetrates into the ground and then the cylindrical portion 56 serves as a guide for the ground anchor 10' in the usually desired vertical alignment of the ground anchor 10 '.

In the tip of the ground anchor 10 'facing the end of the first

Threaded portion 14 is a water outlet opening 24 ', which allows it penetrated into the ground anchor water to drain. 4 shows a third exemplary embodiment of a ground anchor designated in its entirety by 10 ", which differs from the ground anchors shown in FIGS. 1 and 3, in particular by the provision of a projecting collar disk 60 on the cylindrical retaining section 22. Such a collar disk comes When the ground anchor is screwed into contact with the ground and pressed against it, the soil is compacted, resulting in a particularly tight fit of the ground anchor is screwed to the collar disc in the ground, always a certain area of the ground dowel sticking out of the ground, which may be desirable and advantageous, for example, in the permanent attachment of fence posts by means of ground dowels.

It should be emphasized at this point that a receiving portion as shown in Fig. 3 receiving portion 52 can of course also be provided on a ground anchor according to FIG. 1, as well as the described embodiment of Top section 12 '. Also, a collar disc 60 as shown in Fig. 4 can be provided at ground dowels according to FIG. 1 or 3. It is thus readily possible to produce optimally suitable ground anchors for the respective application, eg a ground anchor with a cylindrical holding section according to FIG. 1 and a tip section 12 'according to FIG. 3. The person skilled in the art can advantageously choose the configuration which is optimal for the respective application , Also, it is advantageously possible to form the ground anchor in several parts, the individual parts are then assembled only during use.

For example, the end portion of the threaded portion 14 facing the first displacement portion 16 may be externally threaded and the

Be provided inside the first displacement portion 16 with a corresponding internal thread, so that the ground dowel can be screwed together. This can be particularly advantageous for very large ground dowels, such as those used in the installation of smaller solar or wind turbines, since such ground dowels have lengths in the range of typically 1 to 3 m. If the external threads on the threaded portions 14 and 18 are right-handed, also provided between individual parts of a multi-part ground dowel thread must be right-handed, so that the individual parts of such a multi-part ground dowel when screwing the ground dowel do not come apart. That the parts when unscrewing such a dowel can possibly solve each other, is in many

Use cases unproblematic. In a particularly preferred

Embodiment of a multi-part floor anchor is provided between the individual parts a kind of bayonet connection, such. from German Utility Model 200 00 184 known. Depending on the total length of the ground anchor, it is e.g. possible to form the first threaded portion 14 in two parts.

With regard to the dimensions of the ground anchor the skilled person is largely free, so that he can produce very large, but possibly also very small ground dowel of the type according to the invention depending on the substrate and anchoring object. An advantageous application, for example, the holder of garden lights, which were usually provided only with short Erdspießen so far, but often has led to unsatisfactory support appropriate garden lights. Usual ground dowels with lengths in the range of 60 cm are suitable for most garden lights oversized. A ground anchor according to the invention can also be produced with lengths in the range of, for example, 15 to 30 cm, so that typical garden lights, which usually only have a height of 20 to 40 cm, can be anchored easily and securely in the ground.
