The specific embodiment
Referring now to Fig. 1,, shown in figure as the extrusion 1 of the prior art described in applicant's Australian patent application No.2006202825.Extrusion 1 comprises: body 6, and body 6 can comprise that hollow bulb 6a is to alleviate the weight of extrusion 1; The first branching portion 3 and the second branching portion 4, the first branching portions 3 and the second branching portion 4 extend to limit groove 2 between them from body 6.Groove 2 comprises near outer portion part 2a and the inner section 2b be positioned at groove 2 openings.Be provided with the 7a of shaping surface section that is series of parallel lug, nib form on the innermost wall of the inner section 2b of groove.Branching portion 3 and 4 comprises forming section 5a and the 5b extended in groove.As shown in Figure 3 and Figure 4, forming section 5a and 5b skew is arranged so that when branching portion and retaining member 10 act synergistically, can urge grid member 8 against forming section 5a and 5b.Thereby forming section 5a and 5b cause grid member, bending remains on grid member in groove 2.
Fig. 2 shows the lateral view of framework shown in Fig. 1, can be clear that forming section 5a and 5b therein.Forming section 5a comprises protuberance device or lug, nib device or abutment means, to engage and to clip grid member when grid member is inserted.Forming section 5b is abutment means, and this abutment means also can play the grid member that joint inserts.As shown in Figure 4, branching portion 4 comprises the 7a of shaping surface section that is series of parallel lug, nib form, to assist that retaining member 10 is remained on to appropriate location.
Now specifically referring to Fig. 3 and Fig. 4, wherein show in the groove 2 that is inserted into extrusion 1, mesh member 8 edges before grid member 8 is crooked.Grid member 8 also comprises plastic barrier part 9, for the protection of the edge of grid member.As shown in Figure 3, in ground, 8 one-tenth certain inclination angles of grid member insertion groove 2, make grid member enter the inner section 2b of groove 2.Referring now to Fig. 4,, by being moved and insert retaining member 10 towards branching portion 3, grid member 8 keeps grid member 8.Grid member 8 is moved towards branching portion 3, cause grid member 8 around forming section 5b along first direction crooked and subsequently around forming section 5a along the second direction bending, thereby at two some places, with framework 1, to engage grid member 8 be fastened to framework 1.When grid member 8 moves towards branching portion 3, the edge of grid member 8 engages with the 7a of shaping surface section in the inner section 2b of groove, to prevent grid member 8, moves apart the forming section 5a on the second branching portion 4.Thereby force grid member 8 also around forming section 5a bending.
Referring now to Fig. 4,, show retaining member 10 and be positioned at groove 2.Use mallet or other this type of instrument to force retaining member 10 to enter in groove, all engage with the shaping surface section 7 with grid member 8 and branching portion 4.Force retaining member 10 to enter in groove 2, cause grid member 8 crooked at forming section 5a and 5b place, make grid member be difficult to be moved apart, be even also like this when grid member 8 is applied to external force.
Extrusion 1 can be alternatively at the larger larger grid (not shown) of the outer portion part 2a of groove 2 inner support Thickness Ratio grid member.Therefore, this just make extrusion 1 can either accommodating refined net part again can accommodating larger grid.
Fig. 5 shows according to extrusion 11 of the present invention, and for clarity, uses the same reference numbers for the individual features of prior art extrusion.Extrusion 11 comprises body 6 equally, and body 6 has the first branching portion 3 and the second branching portion 4, the first branching portions 3 and the second branching portion 4 and limit groove 2 between them.The retaining member (not shown) is for the edge to urge mesh member with above-mentioned same mode against the first branching portion 3, and the shaping surface section 7 on the second branching portion 4 contributes to retaining member is remained on to appropriate location in groove 2.
Also be provided with from the second branching portion 4 and substantially laterally extend to the leg member 15 groove 2.This leg member 15 has the fixed end 17 that is connected in the second branching portion 4, and contrary free end 19.Leg member 15 is formed integrally as the part of extrusion 10, and the other parts of the Thickness Ratio leg member 15 of fixed end 17 are narrow.If owing to leg member 15 being applied to any effective power, likely in this narrow office bending, so this narrow allows leg member 15 around its fixed end 17 displacements.
When the mode with same as shown in Figure 4 by the edge insertion groove 2 of grid member in, and while forcing retaining member to enter in groove, the edge of grid member is forced to the free end 19 of against leg member.If apply any shock or other power to grid member, the edge of grid member can be suppressed to the free end 19 of leg member and be blocked the free end 19 by leg member.This is because the shock applied to grid member or other can cause the pulling force grid member edge applied along the direction away from extrusion 20 energetically.When leg member free end 19 butt grid member edge, this pulling force is sent on leg member 15, causes the leg member card by grid member.The power transmitted may cause leg member 15 around its fixed end 17 bendings.Depend on dynamics or apply the number of times of power, leg member 15 will be in groove 2 more and more near-earth towards the first branching portion 3 pivotables.Therefore, the grid member edge can be stuck between leg member 15 and the first branching portion 3 more tightly, makes and more is difficult to grid member is extracted out from groove 2.
