Description

The end covering of window

The present invention relates to covering of a kind of end, sacrificial vessel has the window of framework, window frame and window glass to use.Said covering comprises a bottom and a top, its middle and upper part cover window on the installation site framework and window frame towards outer part, and its middle and upper part limits a chamber transition region between extraneous and window frame and the framework is separated.

The purpose that window is provided with covering be to screen window frame and framework make they be not exposed to extraneous factor like rain under.In order to obtain tight ness rating as well as possible and attractive in appearance, covering preferably is made of few part, and these parts are made by the light-weight metal section bar usually, and this covering is generally used for wood windows.

Have a problem relevant especially with end covering to be, in fact powerful wind energy is rolled rainwater it is entered in the chamber that covering limited.The intrusion of this rainwater for example can cause the rotten of wooden part, thereby the acceleration that causes window damages, rainwater even can invade in the room of window back.

Therefore the objective of the invention is to provide a kind of end covering of window, this covering has the tight ness rating of raising, simultaneously than being easier to cheap expense manufacturing.

Can reach this purpose according to covering of the present invention, its middle and lower part can be divided into this chamber one at the exocoel between the upper and lower and the inner chamber under the bottom.Chamber under the covering being divided into two part back results can causing a different wind mode in covering the chamber, mainly is to produce eddy current in the exocoel between upper and lower covering part, and normally tranquil in the inner chamber under the bottom.Therefore there is a powerful especially wind to force rainwater to enter in the inner chamber.

In a preferred embodiment of the invention, at least a portion bottom tilts with respect to the window glass plane.Present embodiment helps eddy current is concentrated in the exocoel, because the surface that tilts will make windage yaw from inner chamber.

Useful way is the bottom to be installed like this make when window is closed, and does not have or have only minimum opening to exist between inner chamber and exocoel.Present embodiment further helps concentrating of eddy current, can also improve insulating properties.

In a preferred embodiment, the upper and lower is made by single-piece sheet material.Present embodiment has good tight ness rating because there is not joint between two parts, and depends on that manufacture method may save material.In addition, along with the minimizing of number of parts, the danger that covering is installed by mistake also reduces.

In a more excellent embodiment, the upper and lower is made by two different sheet materials.When the pattern of window when being fixed on window glass on the window frame with covering, present embodiment is superior especially.In this case, last covering has a free margins that window glass is pressed on the window frame usually, thus the elasticity that can utilize the sheet material of making covering normally to have.The method of this fixed-pane window can provide light beautiful structure.But top also can just be covered with the clamping accessory, and itself just is not used for fixing window glass like this.

Useful way can connect the upper and lower with the part of opening in a minute, and separately part is the most handy makes than thicker sheet material in upper and lower and/or stronger material.This thicker and/or stronger part provides intensity can for the window frame overall structure, therefore can use extremely elongated window frame member.

In another preferred embodiment, end covering comprises a framework covering to small part cover framework top and side, and this part is disposed in and leaves frame sides one segment distance place.This framework covering provides protection to framework, and makes around can overlapping between the covering of window and the watertight shutter, thus provide one can waterproof connection.

Useful way is that the edge of bottom is terminated on the mid point of that part of framework covering at cover framework top basically.Found once that this overlap joint between framework covering and bottom can be guaranteed good especially waterproof.

Embodiment described in detail shown in following the present invention incited somebody to action in conjunction with the accompanying drawings.In the accompanying drawings:

The phantom drawing of Fig. 1 for cutting open according to the part that is provided with the window of covering of the present invention;

Fig. 2 is along the sectional view of II-II line among Fig. 1.

Fig. 1 illustrates a window which can be propped up family, top 1 that is provided with covering.This covering comprises four major parts, i.e. covering 5 at the bottom of 2,3, top coverings 4 of two side covers and.Each side cover, top covering and end covering all are made of several parts, wherein have at least a part to be used for fixing window glass.For clarity, covering only illustrates external surface in Fig. 1.

Fig. 2 illustrates end covering 5 and is contained at the bottom of the window frame at the bottom of the part 9 and framework on the part 10.End covering 5 comprises three parts, i.e. part 12 and one on glass 13 under framework covering 11, the glass, and covering part on glass the formation, and part constitutes covering part down under the glass.

Framework covering 11 is contained on the framework 10 and part covers its top and side.The part that covers side is disposed in the place of leaving framework one segment distance, thereby can prevent that moisture accumulation is between framework and framework covering.This distance also allows to wash between framework and framework covering along frame sides, thereby the connection of a waterproof can be provided between window and surface on every side.

Part 12 is contained at the bottom of the window frame on the part 9 (usefulness is screw) regularly here and two arm 12a, 12b is arranged under the glass, part 13 on one of them 12a bearing glass, and the transition region that another 12b covers between window frame and the framework is reserved an inner chamber 14, and underarm 12b is just as covering part under the said formation in the claim like this.Underarm 12b partly is stacked on the framework covering 11, and the outermost end of arm is bent downwardly towards the framework covering and only reserves a minimum gap betwixt.If covering 11,12 contacts with each other under framework and the glass, the opening and closing of window will cause unacceptable wearing and tearing so.If desired with space closure, in the bottom of underarm 12b, sealing mat can be set so.

Part 12 is made by the uniform single-piece sheet material of thickness under the glass in the embodiment shown, but upper arm 12a can advantageously have a thickness bigger than remainder, thereby make it have bigger intensity, can have than hard intensity when window frame designs for slender type is an advantage.Perhaps upper arm 12a can be that a part that separates is made by the strong material different with remainder, and for example upper arm 12a can be formed from steel, and the remainder of covering is made of aluminum.

On the level identical, tightened up (usefulness is screw) on glass 13 here on part under the glass with the upside of window glass 6, and covering 11,12 under complete cover framework and the glass.The position of on glass 13 lower end 13b and the lower end of framework covering 11 are very approaching, and extend in parallel with the lower end of framework covering 11, thereby between causes a narrow passage 15.Conceptive this passage 15 should be narrow as much as possible so that stop wind and water intrusion, but minimum widith be need so that allow window open.

The shape of three coverings 11,12,13 is suitable stop wind invade on glass 13 below the chamber in.As mentioned above, 15 limited intrusions that allow wind of throat, and in case after entering in the chamber, this wind will mainly be followed the path shown in the arrow.As seeing on scheming, in fact the little gap of part and inclined surface can stop entering in the inner chamber 14 of wind under the glass, and a narrow neck of the exocoel 16 that constitutes of the bending 13c on glass the top that enters into exocoel that can limit wind.

The task on the window frame 9 of in the embodiment shown window glass being fixed to is done in such a way that and allows a part of 13a of on glass reach on the window glass.When not installing as yet, this extension slightly is bent downwardly as shown in Figure 2.Under the situation of installing, for the space being provided for the window glass sheet, can force this part 13a upwards, make it parallel with window glass basically, at this moment introducing effect forces window glass sheet 6 to be pressed on the window frame 9 and with seal 16 downwards and compresses as the covering 13 of spring.

Also can be a part that separates be fixed tightly on glass 13 with methods such as screw, gluing, welding, riveted joints extension 13a.This embodiment has started with single-piece sheet material and has made on glass and following part 12,13 and can turn back and cause the possibility of extension 13a.

Part 12 extends under window glass 6 and rises along its side under the glass.Be furnished with distance piece between part and the window glass under glass glass window, window frame and covering can be ventilated and move, what for example caused by thermal expansion moves.Distance piece can extend along the whole length of the low part of window frame, but normally uses several along the equally distributed less distance piece of length.The upper arm 12a of part can have the eyelet (not shown) so that cover chamber 16 outside any water that may invade in the distance piece surrounding space is rejected under the glass on its vertical component, can cross under the glass part during discharging and discharges by passage 15.

Covering of the present invention can be made by multiple material, but preferably makes by metal such as aluminium, zinc or galvanized sheet iron or by plastics such as the stable PVC (polyvinyl chloride) of UV (ultraviolet ray).On covering, preferably also apply with the stable material of UV.

Should be noted that top described embodiment just as an example, those skilled in the art can design the same good design of other functions fully.For example the embodiment of covering shown in the figure is designed for the top and hangs the skylight, but should know according to covering of the present invention and also can be used for the window that opens and closes with hinge.
