Most preferred embodiment of the present invention

Be purpose of description, Fig. 1 to Fig. 3 has shown the sports goal of a kind of form of the present invention, roughly is expressed as 10.There is a pair of vertical lateral column 12 at goal 10, pilum 16 behind 14, one of a pair of pilums that extends backwards, a pair of with back pilum 16 each end and corresponding vertical

lateral columns

12,18, one of the oblique lateral columns that the top connects are bound up on the head piece 20 on lateral column 12 tops, and pair of angled post 22.This lower end 24 to tilt column 22 connects back pilum 16 at the some place that contiguous back pilum 16 is held separately, and its upper end 26 connects lateral column 22 at nearby jamb 22 upper ends.

Shown in Fig. 1～3, the side 28 and the back 30 of sports goal 10 have covered adaptive net.In order to erect and be disassembled into portability and the size of depositing that makes things convenient for fast, sports goal 10 is made of together an inflatable framework and an overcoat 34.Framework is designated as 32 in Fig. 4 and Fig. 5.Overcoat 34 is formed and has been worn wire net 28 and 30 by non-elastic material.

Overcoat 34 has a kerf 36 making things convenient on the position, so as to make inflatable framework 32 can plug-in mounting wherein.Because overcoat 34 is to be made of non-elastic material, when inflatable framework 32 plug-in mountings good and inflate after, overcoat will constitute a strong rigid structure.In fact, after sports goal 10 erected, it can easily support to have at least two adult weight of average weight.

Simultaneously, sports goal 10 can also easily erect or remove as required fast, so that carry and deposit.After the dismounting, it only accounts for very little space.In addition, sports goal 10 is very light, and can be floating, thereby it can float on use waterborne in water polo and other aquatic sports.If desired, can sheet 60,62,64,66 alive be set,, perhaps squeeze into

sheet

60,62,64,66 alive with spike in order to admit suitable weight as similar things such as stone, sandbags in the place at contiguous overcoat 34 each angles; Sports goal 10 can be fixed on desired place like this.

The outdoor application because sports goal 10 is everlasting, sunlight will cause the air in the sports goal 10 to expand, thereby under extremity, can set off an explosion.For preventing this possibility, pressure-reducing valve is provided, it by shown in 60, and can see more clearly in Fig. 6 in Fig. 5.These parts 62 can be fixed on the selected position of inflatable framework 32 in the formed opening 64, and it has a flange 66 to cover on the edge of opening 64, can use glue or additive method that valve 60 is fixed in inflatable framework 32.
