Abstract

The utility model relates to a catch capable of automatically closing the windows of a house in wind and rain, composed of a three-connecting-rod mechanism and a slide block with a positioning and locking mechanism. The utility model can cause the window sash to be positioned at any angle no matter whether the wind appears or not, and can automatically close the window in the wind and the rain. After the window is closed, the utility model is automatically collected and folded into a-shaped, and not influences on the installation of a window screen. The utility model has the advantage of simple structure, and is a novel architectural hardware fitting.

Description

Catch capable of automatically closing window

The utility model is the new design about the house window window catch.

Generally using at present has timber window and steel sash window catch, does not possess the function, especially the timber window window catch that close window in wind and rain automatically, in addition the shortcoming that can not regulate the sash aperture and get loose easily.In recent years a kind of " automatic window shutter " of Chu Xianing occurred civilian dress screen window not again and can not keep the new problem of sash aperture when needing wind though overcome the shortcoming of above-mentioned old-fashioned window catch.

The purpose of this utility model provides a kind of new window catch, make its do not influence have under the prerequisite that screen window installs under aperture arbitrarily, make the sash location and no matter wind direction all can close the function of window automatically.

Design of the present utility model is the three connecting rod movable devices that adopt horizontal " A " font to connect with axle.Folding becomes " one " only outwards to stretch when font is windowed when closing window, and locking device and spring are arranged on the connecting rod.When this device artificially locked, sash was positioned, and when unclamping locking device, utilizes spring force that sash is closed automatically in wind and rain.Connecting rod is with nonferrous materials or nonmetals, in order to avoid corrosion.

So do not influence the screen window installation outside screen window because connecting rod only stretches.Owing to adopted locking device, when being arranged, wind can make the sash location can close window automatically again.Bar linkage structure has the advantage of being convenient to produce in batches and be convenient to adopt the anti-corrosion material.

Specify below in conjunction with accompanying drawing.Illustrate to be example with the left-hand side sash all, the situation of right side window can be analogized.

Fig. 1 is the overall installation figure of this window catch.

Fig. 2 is the side sectional view of slide block and coupled part.

Fig. 3 is the schematic diagram after the window catch folding.

The following describes the structure of this window catch.

Earlier referring to Fig. 1.Timber window frame (18) is the following window frame that is embedded in the wall.Sash (2) links to each other with window frame (18) with hinge (1).Linkage is contained between sash (2) and the window frame (18) and plays the window catch effect.

One end of spring leaf (4) is fixed on the sash (2) with screw (3), and the other end links to each other with preceding bar (6) with axle (5).One end of back bar (13) links to each other with axle (17) with preceding bar (6), and the other end is connected on the bearing (15) with axle (14).Bearing (15) is fixed on the window frame (18).Butterfly spring (16) and axle (17) figure that unites all efforts for common purpose clamps preceding bar (6) and back bar (13).One end of strut (8) links to each other with preceding bar (6) with axle (7), and the other end links to each other with slide block (10) with axle (9).Slide block (10) can only horizontally slip on back bar (13).

Again referring to Fig. 2.Handle (11) is being fixed on backstay (20) top, and handle (11) can serve as that axle rotates with backstay (20).Raise one's hand on spring (19) is tried hard to handle (11) and backstay (20).Baffle plate (12) is fixed on the slide block (10), goes to after its height is depressed with handle (11) that unlikely upspringing is as the criterion under the baffle plate (12).Back bar is toothed on (13).

The following describes the movement mechanism of this window catch.Referring to Fig. 1 to Fig. 3.Close the folding of window back link mechanism as shown in Figure 3, become " one " font to crouch on the window frame (18) between sash and screen window, slide block (10) is positioned at the most right-hand.When pushing sash (2) open, linkage gradually stretches, and butterfly spring (16) is opened to be tightened, and slide block (10) moves to left.During to the satisfaction aperture, backstay (20) is inserted in the tooth of back bar (13) by lower handle (11).Because the effect backstay (20) of butterfly spring (16) is pressed on a certain flank to the right, frictional force can not pop up backstay (20).So linkage is no longer active, sash (2) is located.This moment in case of wind and rain then sash (2) should close automatically.Elder generation's false wind pushes away sash (2) left from the right side, by linkage to Zola's slide block (10), thereby laid down the power that backstay (20) is pressed in flank to the right, backstay (20) pops up under the effect of spring (19), leave tooth bar.In case the abatement of wind, owing to the clamping action of butterfly spring (16) makes the automatic folding of linkage become Fig. 3 form, sash (2) is closed.If is wind from the left side? because the heavy curtain motion will be shaken in the inhomogeneities of natural wind and the effect of spring leaf (4) about sash (2) will produce.When sash (2) is the same with the result of above-mentioned three o'clock wind when shaking heavy curtain left, sash (2) is still closed.

The rigidity of selection butterfly spring (16) can be set the size of automatic pass window wind-force.Length of connecting rod calculates and belongs to simple mechanical calculations problem, does not give unnecessary details here.The rigidity requirement of spring (4) and (19) is not tight, can be determined by experiment.

In the time need in wind, keeping the aperture of sash (2), only need handle (11) is pressed the back and turn under the baffle plate (12), backstay (20) sash (2) of can not upspringing then also can be located in wind.

In a word, by lower handle (11) sash (2) is located at an arbitrary position, handle is not interposing at baffle plate following time and can closes window automatically when wind and rain, and following time has wind also can keep the sash aperture even handle goes to baffle plate.

The utility model also has firm, against corrosion, attractive in appearance and is easy to the advantage made in batches except function is more, is the novel Hardware fitting of modern house.
