Abstract

goal cage in play operation of posts and crossbar, made of plastic, metal, Metal alloys or composites, characterized in that that they are made of materials with a memory effect, which give in case of sudden pressure or impact and then take their original form.

Description

The Invention relates to gate housing in the game operation, the two posts and consist of a crossbar, as in the sports Football, handball, hockey or water polo. In this invention it is about materials and dimensions of the gate (gate linkage), So around posts and lath as Torrahmenelemente.

at the ball sports in which teams play against each other and their results are from those in an opposing goal enclosure revealed goals, are the goals in the focus of interest of the active and the spectators.

One Tor essentially consists of three poles - two poles and a crossbar - and a net behind the gate. The Both posts and the crossbar must be stable with each other be connected, and the net must be hung bulletproof and be tautened. Above all, the entire gate must be on the Playfield firmly anchored. To meet these criteria, In the course of sports history numerous materials and constructions have been proposed Service.

In the case of football goals in the large field, the development was based on the replacement of cross-section square wooden posts with round light metal posts. From the protection literature, numerous examples are known, which have a Stabiltätssicherung the goal frame to the content. These include ground sleeves, z. B. in the German (DE) Patent (PS) DE 2847701 A1 , later concrete sleeves, as in the German utility model ( DE-GM) 6948051 in which the goal posts should be firmly anchored. A telescopic construction of the gate frame has been proposed for arresting goalposts and at the same time compensating height differences arising from the exchange of lawns or by leveling measures in the goal area ( DE-GM 29901330 U1 , see. also DE-GM 29901330U1 ).

As another example of a sleeve design, let's look at the scripture DE-GM 20207268 U1 referenced, which has a welded to the aluminum round-bottom plate to the content, with which the insertion depth of the post is to be determined in the ground socket, also to the DE-GM 20215423 U1 , which is based on the proposal to install a guide tube with height-adjustable attachment for fine leveling of the post position in the sleeve relative to the pitch level (see also DE-GM 20207268 U1 , see. also DE-GM 29901330 U1 ). For a door frame with elliptical cross-section and steel-reinforced crossbar, protection was requested in Great Britain in 1992 ( GB 183 677 A ).

With the transport of gates, complete or disassembled, z. B. the property rights

- DE-GM 20303822 U1 This invention relates to a set of wheels for ball game goals as a transport device, which consists of a U-shaped support plate and a two-wheeled axle connected to this sheet together with locking device. A gate post must be prepared with appropriate locking pins before using this device, so that a secured rolling transport can be carried out.

In contrast, the wheels are in accordance with the DE 29802505 U1 firmly mounted on the door frame and can be folded away to the rear.

Examples of folding and hinging mechanisms in the removal of gates may be the fonts EP (European PS) 0934761 A1 and DE-GM 20 2004 012 299 U1 deliver. In the latter, the combination of pivoting side panels and a collapsible lower crossbar of Netzabspannung is described.

Collapsible goals are the subject of EP 0938354 B1 (Placing the door in a transport bag), EP 0938354 B1 and GB 2334896 A (Folding and transport in containers) as well GB 2334896 A whose container serves as a pillar of the gate.

To reduce the risk of injury in a clash of players with the post, especially the goalkeeper, a padded post protection is after DE-GM 7106711 been proposed. However, such protective devices which dampen any impact are not practicable in practice since their influence on the ball behavior during the course of the game is undesirable.

Of the Invention is based on the object, door housing in game operation to develop their materials and dimensions of the gate frame counteract the disadvantages so far. The task was inventively characterized solved that doorsteps in the form of posts and crossbars made of plastics, metals, metal alloys or composites, which give in case of sudden pressure or impact and then return to their original form.

Goal housing for a football goal in large field operation, for example, are characterized in that post and crossbar are round, semi-circular (semicircular) oval or angular and have a width and a depth of 12.1 to 20 centimeters. The inner dimensions of the door in the height between the lower edge of the crossbar and floor are 2.40 to 2.50 meters and in the width between the inside Edges of the posts 7.30 to 8.50 meters, preferably in height 2.44 meters and in the width of 7.33 to 7.80 meters, in particular in the width between the inner edges of the posts 7.66 meters.

The Essence of the present invention is that posts and Crossbar are made as Torrahmenelemente of materials, which have a memory effect. Such materials for the housing parts are metals or metal alloys, in particular Aluminum alloys, also plastics, in particular the memory polymers and Composite materials, eg. B. of coated aluminum or metallized Plastics.

As metal alloys in particular memory alloys (shape memory alloys) come into question. These are alloys that undergo a martensitic transformation (example Nitinol, www.fzs.tu-berlin.de/html/ausr_niti.html ). These include, for example, those containing nickel (Ni) and titanium (Ti) (NiTi alloys) and aluminum (Al) or Al alloys, such as AlTi or AlNi, but especially Al-Ni-Ti alloys. High-quality alloys for the intended purpose are also beryllium-copper alloys as well as certain types of stainless steel used in aerospace applications ( www.ctd-materials.com/products/emc.htm ).

When Memory polymers are called materials that come with a quasi "built memory" are provided, for. Polymers, the below their melting range their shape depending can change reversibly from the temperature. Such properties show plastics that are made of a hard (inelastic) and a soft (elastic) polymer are constructed.

Another group is the IPN polymers (interpenetrated polymer network). IPN is a proven, particularly homogeneous compound of polymethyl methacrylates, whose copolymers are highly cross-linked and free of fillers. They consist of two interpenetrating but non-interconnected networks ( www.apv.ethz.ch/download/5_Sem/Galenik/s_polym1.pdf ).

These include EMC (Elastic Memory Composite) materials, as resin matrix or fiber reinforced in many variations ( www.ctd-materials.com/products/emc.htm ).

Also suitable is the high performance plastic PTFE (polytetrafluoroethylene, sometimes referred to as polytetrafluoroethene) from the class of polyhalogenolefins. A special manufacturing process (Elring Memory, ElringKlinger) results in a memory effect ( www.elringklinger-kunststoff.de/pages/w_presse.html ).

As composite materials z. B. glass-epoxy composites with EMC effect in question ( www.ctd-materials.com/products/emc.htm ), but especially those made of coated aluminum or metallised plastics. A special position among the aluminum composites is taken by the TECE composite pipes (TECEflex). These "intelligent" metal-plastic compounds with memory effect have their firm place in the market z. B. as tying and distribution systems for drinking water and heaters found. TECEflex composite pipes combine the optimum properties of metal and plastic pipes. They meet all requirements for pressure and temperature resistance. Additionally applied aluminum and plastic layers, they owe their above-average safety reserves and their kink resistance ( www.tece.de/produkte/teceflex/teceflex_verbundrohr.php ).

One Another field of this invention relates to the dimensions of Gate frame (gate linkage) and the gate housing, including posts and lath as goal frame elements. In the case of a football goal in large field operation should post and crossbar round, half round (semicircular) be formed oval or angular and a width and a depth from 10 to 20 centimeters, in particular 13 to 16 centimeters, preferably 14 centimeters. The internal dimensions of the door housing should according to the invention in the amount between Lower edge of the crossbar and bottom 2.40 to 2.50 meters and in the Width between the inner edges of the posts 7.30 to 8.50 meters amount, in particular in height 2.44 meters and in the Width 7.33 to 7.80 meters, preferably 7.66 meters in width.

From Companions of the football match are critically led into the field, that it is a sport that suffers from that too few goals are scored (0: 0, 1: 0, 1: 1 ...). In tournaments like continental or world championships, lead in the k. o.-phase too many Play in extra time or even end in gambling (Penalties shoot). But if the football goal something would be enlarged, just about the two Post, then all the post-shots would be then Goals, and through the new postshots would come the ball back into the game. By something bigger Goals would be achieved that strengthened the attacking football and the defensive football pushed back accordingly would. It would come to more scores the second series - and the corresponding ones Goalkeeper saves. The attacking team would be stronger advantageous than the current system. And the spectators were rewarded by what they really want to see: attacks, shots, Goalkeeper saves.

At The rules should not change, only that the penalty (penalty) at 12 to 14 meters, preferably would be relocated to the 13-meter point. With the proposed changes The character of martial arts football would remain untouched, and the expected increase in the number of goals also not to the fact that now handball results would come about.

at the question of a further revival of the football game and with slightly bigger football goals also asked the question of the dimensions of the gate linkage with posts and lath as Torrahmenelemente. In case of - rather slight - increase the width of Post and crossbar increase the number of post and lath shots. The Of course, it would be very convenient for the spectators to take in the murmurs on the ranks after such events is. This would return the ball more often into the game and then, of course, close to the goal, which finally also in the sense of the audience would be.

The Features of the invention will become apparent from the elements of the claims and from the description, showing both individual characteristics as well as several in the form of combinations advantageous embodiments for which protection is sought with this document becomes. The essence of the invention is a combination of known (Gate housing from posts and crossbar) and new elements (materials with memory effect, changed dimensions), which are influence one another and one in their new overall effect Utility advantage and the aspired success, which lies in that the risk of injury to the players at the posts reduces and the attacking football an affirmation He leads.

The Invention will be explained with reference to embodiments without being limited to these examples.
