Description

Invade protecting screen

Invention field

The present invention relates to a kind of intrusion protecting screen that window, gateway etc. are located that is used for, particularly be used for the protecting screen of safety guarantee and block insects.

Background technology

Screen board or grid are used to improve the safety of building sometimes.For example, the steel bar grid enters the house in order to stop the effractor by door or window.When being used on the window, the steel bar grid is solid near the metope the window by bolt.Be used in when last, the steel bar grid by with pivotal mounting in gateway, and use as additional door.

People generally believe that the steel bar grid is repugnant to the eye, so it only is used for industrial construction, shop and some commercial locations usually.And the distance between the grid steel bar is all wide usually as to be enough to allow screw cutter or hacksaw enter with the cutting steel bar, so this grid can not guarantee safe enough all the time.

Protective screen is often used in the prevention effractor and enters the house by door or window as a substitute mode of steel bar grid.Burst disk comprises that extrudes a framework, covers by extruding the zone that framework surrounds with a wide checkerwork cell net.Wide checkerwork cell Netcom often has the elongate articles that diameter is 7mm, and the mesh spacing is approximately 60mm.Hole pattern is installed in the slit of framework usually, and is not clamped to framework usually.The wide checkerwork cell net of one of reason is normally made by expansion aluminium, because itself and framework contact surface are too little, and is unsuitable for using bolton.And the profile of hole pattern requires accurately, also to require at the special alignment of each screen screw, and this has just strengthened workload.Thereby, have potential effractor movable part or whole from the framework not by the possibility of the solid hole pattern of spiral shell.

This type of protective screen has the defect property same with the steel bar grid, and promptly hole pattern may cut with bolt cutter or hacksaw.

When relative window or door are opened when giving house ventilation, the safety that above-mentioned screen or grid can provide is just very limited.Yet these screens or grid do not have the effect of block insects, so sometimes for block insects, and fine-meshed screen and protective screen or grid are united use.Fine-meshed screen is installed on the wooden frame usually, or on the keyway that extrudes framework of screen, a rubber strip is arranged in the keyway, is used for fixing the limit of hole pattern.

Above-mentioned fine-meshed screen can not prevent the effractor, because wooden frame can be destroyed easily, or hole pattern can be removed from keyway easily.Also have, normally thin nylon of fine-meshed screen or fine wire are made, and are easy to destroyed.Thereby can only the provide safeguard function of safety and block insects of normally used pore screen, protective screen or safety grids also exists to increase and makes and the shortcoming of mounting cost limitedly.

No. 694515 patent of our Australia described a kind of scheme that solves existing issue, this patent disclosure a kind of intrusion protecting screen, the wire that includes braiding is invaded the protection hole pattern.The inventor has realized that now the modifying device of fixing this hole pattern is feasible.

The specific embodiment

As shown in Figure 1, show a kind of intrusion protecting screen 1, the intrusion protection hole pattern 4 that this framework 2 comprises a plurality of elongated shape frame partss 3 and is clamped to frame parts 3 with a framework 2.

Hole pattern 4 covers the opening that is surrounded by framework 2.Hole pattern 4 is the nets that formed by the stainless steel wire braiding.In No. 694515 patent of Australia, the hole pattern size that is fit to has been described.Have found that optimal hole pattern is of a size of: wire diameter be 0.8mm to 1.2mm, and the spacing between the wire (broadwise and warp-wise) for 1mm to 2.2mm.

Referring to figs. 2 and 3, Fig. 2 and Fig. 3 show an embodiment of frame parts 3.Frame parts 3 is formed by aluminium extruded system, has a slot part 5, and each end of this slot part 5 all can hold a knee brace.By frame parts 3 is cut into suitable length, and they are fitted together, thereby make framework 2 with required form and size with tiltedly piecing together the angle.Though frame parts 3 is preferably the microscler thing of the aluminium that extrudes (length), also can select for use any suitable material with the microscler thing that extrudes, method such as rolling, punching press forms.

Be provided with the clamping part 6 of an one and the clamping part 7 of a non-one in groove 5 inboards, these parts 7 are individually formed with respect to frame parts 3.Clamping part 6 is identical with clamping part 7 length, and along the elongated lengthwise of framework 3.Be drilled with several isolated holes along clamping part 6 and clamping part 7, holding securing member such as Pop rivet 8 (pop-rivet) or screw, they and clamping part 6 and clamping part 7 actings in conjunction are clamped in framework 2 to hole pattern 4.Thereby, after clamping, a zone on each independent limit of contiguous hole pattern 4 is clamped to framework 2, the remainder that zone that each is clamped and mesh 4 are centered on by framework 2 is in same plane, as a result, each limit of mesh 4 all is clamped at being no more than on the clamping surface of each clamping part 6 and clamping part 7.

The upper surface of clamping part 6 is zigzags, to provide stronger confining force to mesh 4.This sawtooth has obvious improvement in our described invention of early stage patent, the line that it catches on hole pattern more effectively clamps hole pattern.The soffit of clamping part 7 also can be a zigzag, as shown in Figure 4 and Figure 5.

Wall part 9 the extending internally of one from slot part 5.At the free end of wall part 9, be a flange portion 11, it extends to hole pattern 4, and supports clamping part 6.

Lip 12 and slot part 5 be one and extend internally from slot part 5, constitute groove 13 with wall part 9, this groove 13 can hold a limit of clamping part 7 and a limit of hole pattern 4.This lip 12 adjoins clamping part 7, when clamping, assists to keep clamping part 6 and clamping part 7 parallel to each other.

And clamping part 7 has two slits 14,15, and the length direction that is parallel to parts 7 is offered, and in order to an attached elasticity cover fillet 16, it covers the head of Pop rivet 8.

As shown in Figure 3, two frame partss 3 are in a corner of framework 2, knee brace 10 are plugged in the slot part 5 of frame parts 3 of mitered, and two frame partss 3 are linked together.Afterwards, holing on each limit of frame parts 3 and on the knee brace 10, again Pop rivet 17 is being inserted, so that frame parts 3 is fastened on the knee brace 10.

Figure 4 shows that second embodiment similar, but, on the soffit of clamping part 7, also be formed with sawtooth to first embodiment shown in Fig. 2.

Sawtooth one same-action on the soffit of the upper surface of clamping part 6 and clamping part 7 is securely fixed in hole pattern 4 on the frame parts 3.Securing member 8 is fixed clamping part 7 with respect to clamping part 6, thereby makes hole pattern can stand strong impact, and is not drawn out framework.

Among Fig. 4, the terminal of this lip 12 is hooks 18, and it is located in the narrow groove 19, with respect to frame parts 3 thereby also locate clamping part 7 definitely with respect to clamping part 6.Hook 18 and narrow groove 19 combine provides the clamping of the strong leverage of hole pattern 4 by provide a pivoting point to help for clamping part 7.

The 3rd embodiment also illustrates at Fig. 5, but, has increased and has been with 20 on the edge strip that covers hole pattern.The inventor finds, on the contact point of stainless steel hole pattern and aluminium chassis, can corrode.Plastic strip, such as electrical insulation tape, can head it off.

In the use, invade protecting screen 1 and can be installed on the gateway hinge, or be fixed on the window frame in any known mode.Hole pattern 4 causes difficulty to the effractor, makes it can not obtain enough big hole and enters, can't be with screw cutter saw or cutting, the also enough block insects of the rank of hole pattern (order number).And, when using stainless steel hole pattern 4, will cause more complicated difficulty to possible effractor, because stainless steel has the characteristic of passivation cutting tool.

The clamping of hole pattern provides additional intrusion barrier propterty, because wall part 9 is positioned at the outside of gateway or window, thereby possible effractor cannot see securing member 8.When the inside is seen, securing member 8 is hidden in and covers under 16, and it has the color that the jaw portion with parts 7 is complementary.

Though as with reference to having described the present invention, should be appreciated that the present invention is not limited to specific embodiment described here with preferred embodiment.
