Description

The window safety grid

The utility model relates to the Anti-theft door and window facility.More particularly belong to the window safety grid that is used for enclosed balcony or other window.

In the last few years, for strengthening the safety of social security, protection people lives and properties, many safe precaution measures and facility had been adopted.Window is exactly wherein a kind of with safety grid.At present, the balcony of Urban House building seals with window mostly.The balcony window of this sealing both can keep good daylighting, and the heat in the holding chamber is welcome by the resident very again.For increasing safety, theftproof, many residents have installed the window safety grid again.This anti-thefting facility is mostly made with the steel pipe welding, is difficult to destroy, and safe and reliable, still, in case indoor the generation such as fortuitous events such as fire, homicides, this window often stops or hindered the escape of indoor occupant again with safety grid.In order to address this problem, the resident who has has prepared broadax on the window side, in case of need.But this facility is very heavy, very inconvenient, can damage safety grid even building again.Except that balcony window, some other window such as French window etc. also have this situation.

The purpose of this utility model is to overcome above-mentioned shortcoming and defect, provide a kind of and both be difficult to destroy, safe and reliable, good theftproof performance is arranged, can when unintended emergency situations such as breaking out of fire, homicide, escape smoothly again; Both firmly solid, as can open certain part rapidly again, can not to damage window safety grid.

In order to achieve the above object, the utility model by screen frame, weld or be connected in net lattice, anchoring in the screen frame and bury and be contained on the building and constituted with fixture that screen frame is connected.Fan with the articulated escape of hinge on screen frame or the net lattice.The escape fan is fastened in the fan frame of forming with part screen frame and net lattice.The escape fan is made up of frame and welding fan lattice wherein.The lock that the escape fan can be locked in the fan frame is installed between the two.The lock that uses can be a common lock, also can be special.It is by the lock body that is installed in fan frame top and bottom belt length square hole, fastening is fastened on the locking closure that forms the lock chamber on the lock body, be installed in its laterally skewback that vertically has the screw vertical with holes that to slide therein in the lock chamber with transverse holes, being installed in lock can slide up and down the lower end in the chamber and can extend out to dead bolt the oblong aperture on the frame of escape fan from the oblong aperture of lock body, be installed in two guide pillars above the dead bolt, be enclosed within two springs that are arranged in lock body on the guide pillar, be installed in dead bolt top and can and be pressed against roller on the inclined-plane of skewback around little axle rotation, be installed in the transverse holes of skewback to be installed in the fixing wire rope of holding screw in the screw and to be constituted with cable wire pulling mechanism that the other end of wire rope is fixedly linked.

Cable wire pulling mechanism can be made of the caliper brake for bicycle brake lever on the reference column that is fixed on screen frame or other fixed position.Wire rope then is made of with wire rope and sleeve pipe thereof caliper brake for bicycle, also steel wire penetrating can be fanned accordingly in the steel pipe of frame, screen frame, net lattice to constitute.

Under normal mode of occupation, the escape fan is locked in the fan frame, and the utility model plays antitheft effect safely and reliably.During situation such as breaking out of fire, homicide, owner can will lock unlatching again very soon, and the fan of will escaping is opened and turn to outdoor escape or temporarily hides., can directly jump out at Stall as balcony., more than second floor, can wait by the fire fighter and scoop out escape as balcony.When nobody scoops out really, also can borrow the escape fan temporarily to hide outdoor.As the fan of escaping go up to install is common lock, uses key to open.As what install is lock of the present utility model, then without key.Firmly depress to hold brake lever, cable wire will be drawn out of displacement along sleeve pipe or steel pipe.And then skewback pulling moved to right, skewback is oppressed roller again and is made it to extract out from the oblong aperture of frame until dead bolt together with moving on the dead bolt.The escape fan just can be opened, and it is outwards turned down along the hinge rotation.During locking escape fan, brake lever is depressed made the dead bolt rising earlier.The fan of will escaping again fastens.Unclamp the brake lever of holding at last, dead bolt just moves to left skewback under the pressure of spring and resets, and dead bolt stretches out simultaneously the escape fan is pinned.Except that brake lever, can also use other cable wire pulling mechanism.No matter push away, draw, press, step on, which kind of cable wire pulling mechanism that the escape fan is opened all can.

When having horizontal fan lattice on the escape fan, the escape fan that turns up becomes ladder, is convenient to climb down or steps down on the fan lattice and keep away temporarily.

Task of the present utility model comes to this and finishes.

The utility model provides a kind of good theftproof performance that has, and is strong, safe, reliable, can open the escape smoothly of escape fan again as early as possible when fire, homicide, practical and convenient window safety grid.It can be widely used on the balcony window, French window of buildings such as residential building, office premises.

Below in conjunction with embodiment and accompanying drawing thereof the utility model is done further explanation.
