Description

Extrusion with security feature

Technical field

The present invention relates to a kind of extrusion, and relate to the extrusion with security feature of the framework that is used for door or window particularly.The present invention is suitable for use as safety door framework or safe window framework.

Background technology

Safety door and safe window are installed in house etc. usually, to prevent without fixed duties or the person non grata enters.The main effect of safety door provides a kind of do not allow to desire invador's arm or the grid member that leg enters by gateway or window.This grid member is supported in the framework usually.

Safety door and safe window often comprise the mesh member of two kinds of forms.Normal use the personnel that prevent enter gateway than refined net spare, and be grid form than macrolattice spare.Yet, can easily be out of shape than refined net spare, and that grid allows that instrument stretches into is indoor, so the dwelling house occupants that is combined into of macrolattice and refined net provides safety.Yet grid may be not too attractive in appearance and hinders and see through door or window is watched.Therefore, the recent safety door and the design of safe window used individual layer than refined net spare, should make by for example stainless high-strength material than refined net spare, and without any need for bigger mesh member.

These designs only can be used in support and can not be used for than refined net spare supporting than macrolattice spare.

To be fixed to framework than refined net spare by screw or rivet, in order will remaining in the framework, need in attached framework of edge and grid member, the hole to be set all than refined net spare.

Yet,, for example play or with heavy instrument bump grid member, this machanical fastener has the trend of shear strain, thereby grid member can not be fastened in the framework if grid member is applied very large power.Another shortcoming that may occur is, when applying enough big power on grid member, described hole is variable big and tear, and grid member is unclamped from framework, thus in the personnel of the permission inlet chamber or by force for example the apparatus of cutter stretch into indoor.

The applicant has developed a kind of extrusion that can overcome one or more shortcomings in the above-mentioned prior art.Described this extrusion among this application people's the Australian patent application No.2006202825, incorporated its detailed content into this paper by the reference mode.But expectation provides a kind of and improved security feature is provided and has overcome the extrusion of one or more shortcomings of above-mentioned prior art for safety door and safe window.

Summary of the invention

Consider these, the invention provides a kind of extrusion that uses in the framework of safety door or safe window, this extrusion comprises: body; First branching portion and second branching portion, first branching portion and second branching portion extend and limit the groove at the edge that is used to hold mesh member between first branching portion and second branching portion from body; And

Gripping mechanism, this gripping mechanism be used for mesh member is applied the bump or other situation energetically under with the mesh member edge card in groove.

Gripping mechanism can comprise leg member, this leg member has the fixed end that is connected in a described branching portion, and being used for opposite free end with the mesh member edge join, this leg member can make that free end can be towards relative described branching portion displacement around its fixed end displacement.

Leg member can be formed integrally as the part of extrusion, and can comprise flexible part at its fixed end.

The present invention also provides a kind of door assembly, framework and retaining member that it comprises mesh member, is formed by above-mentioned extrusion, this retaining member between branching portion so that the mesh member edge is remained in the groove.

In with the retaining member insertion groove, the edge that urges mesh member is during against leg member, the free end of leg member can with the edge join of mesh member.When mesh member being applied bump or other energetically the time, this plays and causes the effect that act as the pulling force that this edge is pulled out in the groove along the mesh member edge.Since the free end of leg member can with this edge join, drop on the leg member so this causes grid member to be forced to, thereby on the free end of leg member, apply power.Therefore, leg member can be close to grid member by card.Leg member can have can be around the part of its fixed end bending, and can be therefore when its free end is applied enough big power around its fixed end displacement.Therefore, leg member can pivot towards relative branching portion around its free end, thus also with the mesh member edge card between relative branching portion and leg member.When mesh member was applied further power, the movable one-tenth of leg member was more near relative branching portion, further improved the chucking degree in the groove of framework, thereby made and be difficult to more the mesh member edge is extracted out in groove.

Therefore, extrusion according to the present invention more and more is difficult to mesh member is extracted out from the framework of being made by this extrusion energetically the time mesh member being applied multiple bump or other by making, a kind of improved security feature is provided.

The specific embodiment

Referring now to Fig. 1,, shown in the figure as the extrusion 1 of the prior art described in applicant's the Australian patent application No.2006202825.Extrusion 1 comprises: body 6, body 6 can comprise that hollow bulb 6a is to alleviate the weight of extrusion 1; First branching portion 3 and second branching portion, 4, the first branching portions 3 and 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 that is positioned at groove 2 openings.On the innermost wall of the inner section 2b of groove, be provided with the 7a of shaping surface portion that is series of parallel lug, nib

form.Branching portion

3 and 4 comprises forming section 5a and the 5b that extends in the 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 and urges grid member 8 against forming section 5a and 5b.Bending remains on grid member in the groove 2 thereby forming

section

5a and 5b cause grid member.

Fig. 2 shows the lateral view of framework shown in Figure 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 an 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 portion that is series of parallel lug, nib form, to assist that retaining member 10 is remained on the 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, is used to protect the edge of grid member.As shown in Figure 3, make grid member enter the inner section 2b of groove 2 in ground, 8 one-tenth certain inclination angles of the grid member insertion groove 2.Referring now to Fig. 4,,, grid member 8 keeps grid member 8 by being moved and insert retaining member 10 towards branching portion 3.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 to engage with framework 1 grid member 8 is fastened to framework 1 at two some places.When grid member 8 when branching portion 3 moves, the edge of grid member 8 engages with the 7a of shaping surface portion in the inner section 2b of groove, moves apart the forming section 5a on second branching portion 4 to prevent grid member 8.Thereby force grid member 8 also around forming section 5a bending.

Referring now to Fig. 4,, shows 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 the groove, all engage with shaping surface portion 7 with grid member 8 and branching portion 4.Force retaining member 10 to enter in the groove 2, cause grid member 8 crooked, make that grid member is difficult to be moved apart, even when grid member 8 is applied external force, also be like this at forming

section

5a and 5b place.

Extrusion 1 is the support thickness big grid (not shown) bigger than grid member in the outer portion part 2a of groove 2 alternatively.Therefore, this just make extrusion 1 can either ccontaining refined net spare again can ccontaining bigger grid.

Fig. 5 shows according to extrusion 11 of the present invention, and for clarity, is used for the same reference numbers of the individual features of prior art extrusion.Extrusion 11 comprises body 6 equally, and body 6 has first branching portion 3 and second branching portion, 4, the first branching portions 3 and second branching portion 4 and limit groove 2 between them.The retaining member (not shown) is used for the edge that urges mesh member with above-mentioned same mode against first branching portion 3, and the shaping surface portion 7 on second branching portion 4 helps retaining member is remained on the appropriate location in groove 2.

Also be provided with from second branching portion 4 and laterally extend to leg member 15 groove 2 substantially.This leg member 15 has the fixed end 17 that is connected in second branching portion 4, and opposite free end 19.Leg member 15 is formed integrally as the part of extrusion 10, and the thickness of fixed end 17 is narrower than the other parts of leg member 15.If because leg member 15 were applied any effective power, then might be in this narrow office bending, so this narrow allows leg member 15 around its fixed end 17 displacements.

In with mode same as shown in Figure 4 edge insertion groove 2 with grid member, and when forcing retaining member to enter in the groove, the edge of grid member is forced to the free end 19 of against leg member.If apply any bump or other power to grid member, then the edge of grid member can be suppressed to the free end 19 of leg member and be blocked the free end 19 that leans on leg member.This is because the bump that applies to grid member or other can cause the pulling force that the grid member edge is applied along the direction away from extrusion 20 energetically.When leg member free end 19 butt grid member edges, this pulling force is sent on the leg member 15, causes the leg member card by grid member.The power that is 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 pivot towards first branching portion 3.Therefore, the grid member edge can be stuck between the leg member 15 and first branching portion 3 more tightly, makes more to be difficult to grid member is extracted out from groove 2.

It will be appreciated by those skilled in the art that easily to foregoing invention carry out describing modification and remodeling more specifically.Should be appreciated that and the present invention includes all these modification and remodeling.The present invention also contain in the manual with the arbitrary of two or more features or all combinations separately jointly alleged or shown in all features and product.
