DE202004006177U1 - Ground spike for parasol and other fittings has a demountable spike at the bottom of an upright tube and with a bracing plate to support the fitting on the ground - Google Patents

Abstract

A ground spike for a parasol or other upright fitting has an upright metal tube (10) with an internal thread (11A) in the bottom end. A ground spike (20) is fitted with an upper plug (21) with an outer thread to secure into the bottom of the support tube. A bracing plate (30) with a central threaded hole is fitted over the plug, leaving sufficient thread to take the support tube. The plate braces the fitting onto the ground and relieves stress on the ground spike. For safe transport the ground spike is inverted and screwed into the support tube.

Description

technical background

The invention relates to a holder for anchoring a rod-shaped Component, especially the mast of a parasol, in the ground.

In contrast to pure feet that (possibly weighted by weights in the form of plates) over a largely have a flat footprint solutions known, by means of pluggable, knockable or in the ground drivable cylindrical tubes without a footprint to achieve sufficient support, especially an umbrella.

State of technology

A generic bracket is for example from the DE 203 03 479 U1 known, in which a conical core is provided at the lower end of the shaft for easier submergence in the ground, which carries a spiral spiral to improve the holder.

A similar solution shows the DE 199 37 138 A1 , where to improve the stability of a support foot for a protective screen at the lower end of the tip of a mandrel an external thread is provided which can be screwed into the ground.

The disadvantage of this and other known solutions is in particular that in order to achieve sufficient stability of the in the soil can be driven in relatively large Diameter required which leads to a safe driving of this foot to a minimum depth in the Soil involves considerable effort, which often only applied with tools such as a hammer can be. Due to the small side surface of the foot, it is still not guaranteed that the earth mandrel is levered out by the considerable wind forces, especially since appropriate coverings such as parasols, wind sails, canopies or similar at heights from mostly about 2 m above are attached to the ground and thus the occurring wind forces into one lead to a significant tipping moment on the earth mandrel sunk in the ground.

The conical taper of most earth spines for easier driving into the ground also have the disadvantage that during transport and storage of the bracket or the Parasols pose a significant risk of injury if used improperly entail.

With such mounts in the ground anchored flat Textiles therefore pose a considerable risk of accidents, both in the introduced Condition, as well as in storage and transport condition.

presentation the invention

It is therefore an object of the invention to create a bracket for anchoring that is structurally simple, easy to use and safe in its intended function and during transportation and storage.

According to the invention, this object is achieved according to the features of protection claim 1 solved.

The basic idea of the invention is to be seen in the fact that the earth mandrel previously used has the holding function now shares with a laterally projecting support element, the more preferred Formed as a plastic plate, but also other suitable Can have shapes. This side support element lies on the floor surface, so the torques exerted by wind forces into the ground surface can be initiated so that the earth rod can be dimensioned accordingly smaller and consequently faster and easier and without using Tool can be driven into the ground until the support element lies on the floor.

This concept enables one particularly advantageous embodiment such that the earth mandrel either from the receiving tube (as usual) stands out, but also in its transport or storage position in the correspondingly larger one Receiving tube can be inserted and fixed there, so that in particular the tip of the earth mandrel is secured by the receiving tube and there is no longer any risk of injury or accident.

Building from a few, easy to manufacturing components an inexpensive Production and simple, uncomplicated handling.

Further refinements of the invention are further subclaims refer to.

Short description of the drawings

A preferred embodiment the holder according to the invention is now explained in more detail with reference to drawings, which show:

1 : A first sectional view of the holder in the functional position with Erddorn inserted into the earth, and

2 : the bracket according to 1 in their transport and storage position.

description of the embodiment

The holder according to the invention essentially consists of three basic components, a receiving tube 10 with the mother inserted at its lower end 11 with internal thread 11A , an earth thorn 20 with an inner element attached to its upper end 21 with external thread 21A , and one on the inner element 21 Support element extending perpendicular to the axis of the receiving tube and the earth mandrel 30 , which is plate-shaped here.

The outer dimensions of the inner element 21 and its thread 21A are dimensioned so that it into the internal thread 11A mother 11 can be screwed in, as is to be shown in the drawings by the curved arrow.

mother 11 and interior element 21 can on the receiving tube 10 or the earth thorn 20 jammed, glued or welded, depending on the materials used for these components; In principle, constructions made of metal or plastic are conceivable, whereby for the earth mandrel with a diameter of 6 mm, spring-hard, rust-free stainless steel is preferred, and the 40 cm long receiving tube, for example 10 made of aluminum.

The support element 30 consists of a disc, preferably made of plastic, in its central area with reinforcing elements 30A is provided, either fixed to the inner element 21 are connected or, if necessary, can also be screwed onto this by appropriate design.

The support element has in the peripheral region 30 an edge area bent downwards 30B on, which is used to claw the bracket in the ground. Correspondingly, additional elements can also be formed from the surface and bent or angled downwards by shaping the support element, in particular from plastic, in order to reinforce this effect.

Preferred dimensions are 21 mm for the inner dimension of the receiving tube 10 to fit a mother 11 with a 3/8 inch internal thread and an external dimension of 25 mm, as well as an earth mandrel 20 with an external dimension of 6 mm. The support element can preferably be a plastic plate with a diameter of 170 mm, with a variable mounting on the inner element 21 Depending on the expected wind or other standing load, smaller or larger support elements can also be used 30 be used.

The two figures show the two relative positions of the receiving tube 10 and earth thorn 20 :

In the functional position as a holding element ( 1 ) becomes the inner element 21 with the earth thorn pointing down into the mother 11 of the receiving tube 10 screwed in until the receiving tube 10 on the support element 30 sits (shown in dashed lines). In this mounting position, the bracket is ready for use and the earth spike 20 is driven into the ground until the support element 30 rests on the floor and its edge bends 30B have buried themselves in the ground for additional support. After assembly, it can then be inserted into the receiving tube 10 For example, the mast of a parasol can be inserted from above, or also a holding tube for an awning, a canopy or a sun sail or the like. You can do this at the top of the receiver tube 10 Mounting and locking elements of known type may be provided, which are of no interest here and are also not shown in the drawings.

After the holder has been used as intended, it is pulled out of the ground, the earth mandrel 20 becomes from the receiving tube 10 unscrewed and screwed back in the opposite direction, so that the earth mandrel 20 in the receiving tube 10 lies and is secured coaxially to it ( 2 ). The lengths of earth thorn 20 and the receiving tube are matched to one another so that the tip of the earth mandrel is completely in the receiving tube 10 is included.

In this transport and storage position the holder can be transported easily and without risk.
