BRIEF SUMMARY
BACKGROUND TO THE INVENTION
THIS invention relates to a frame which is movable between an assembled position and a folded position, particularly a frame which may be used, when covered with a net, as a goalpost, or the like.
One of the most popular sports in the world is football or soccer. Many children and adults would like to be able to play soccer either in their gardens or on other pieces of land not laid out as regular soccer pitches, but one difficulty in this regard is the provision of a suitable goalpost. Generally soccer goalposts are rigid structures which take up a fair amount of space. Certain types of collapsible goalposts have been proposed as set out below.
This reference discloses a collapsible sports goal where the various segments of the poles forming the goal are held together by an elastic cord. The elastic cord is not tensioned to hold the segments together, rather, the segments are held together by connector sleeves.
This reference discloses a goal frame which includes a pair of front upright members which are coil springs, and a rigid connecting upper transverse member.
This reference discloses a goal frame which includes a number of tubular frame members which are connected to each other to form the frame by means of helical spring connectors.
This reference discloses a goal post which consists of two uprights supporting a horizontal cord. The uprights each consist of an upper rod fixed in an elastic base. The tension in the cord can be adjusted by altering the elastic elements of the base.
This reference discloses a goal post assembly comprising two uprights, a crossbar and supports assembled from releasably interconnected sections using corner pieces. Each upright or crossbar may be made from a number of sections. At each joint between sections there is provided a spring which permits removal of one section from the end of its neighbour but not total separation.
This reference discloses a folding sports goal made from tubular elements, each element have a conical end designed to fit in a conical bore in an adjacent element, and joined by an elastic cord. The uprights and the crossbar are formed from a number of tubular elements which are held together by two elastic cords. One end of each cord is attached to a spring which the other end of each cord includes a ring which attaches to a hook to hold the tubular elements in position.
There is however a need for a goalpost for soccer, street-hockey, hockey, water polo, and other games which can be easily assembled and then disassembler when not needed, and which is easy to store and easy to use.
SUMMARY OF THE INVENTION
According to a first aspect of the invention there is provided a frame movable between an assembled position and a folded position which comprises: and a second end, the second end of the first length of tubing being connected to the first end of the second length of tubing, the second end of the second length of tubing being connected to the first end of the third length of tubing and so on with the second end of the nth length of tubing being connected to the first end of the first length of tubing to form a closed circuit, each length of tubing forming a side of the frame; second end of an adjacent length of tubing, the connectors being adapted to permit two adjacent lengths of tubing to be arranged at a first angle to each other in the assembled position of the frame and at a second angle to each other in the folded position of the frame; and hold the lengths of tubing and the connectors in position in the assembled position of the frame and to permit the frame to be moved between its assembled position and its folded position.
Obviously, the frame must include at least three lengths of tubing. Preferably, the frame consists of six lengths of tubing to form six sides, and thus six connectors.
When the frame consists of six lengths of tubing, preferably the first length of tubing and the fourth length of tubing are of the same length and the second length of tubing, the third length of tubing, the fifth length
