Abstract

The utility model discloses an automatic positioning wind-proof device for doors and windows, which comprises support rods, auxiliary supports, toothed plates, the sliding shaft of a sliding plate, torsion springs, etc. The utility model makes use of the driving force of the torsion spring to spring pawls on both ends of the toothed plate for making the sliding shaft tightly engaged with positioning teeth. The doors and windows can be automatically positioned on a required opening position, and the support rod and the auxiliary support form a Y-shaped support state during opening. The structure forms an I-shaped folding and is concealed inside the door and window frames after the closing of the door and the window. The utility model avoids the defects the prior wind bracing extends into a room and blocks up persons and objects. The utility model has simple structure, easy application, reliable positioning, flexible and convenient opening and closing, and adjustable opening, can relieve the gale shock, and protect the door and window.

Description

Automatic positioning wind-proof means for doors and windows

The utility model relates to the wind-proof device of architectural hardware member, particularly wing.

Wind-proof device on the door and window is a requisite accessory kit on the builing industry especially for the wind-proof device on the glass window, and the past is used the window catch hook always, and this window catch easily comes off fragile, is unable to undergo big wind and scrapes.The aperture of door and window also can't be regulated, replaced by wind brace gradually,, perhaps have the fixing arbitrarily structure of screw owing to be processed with a plurality of locating holes on the wind brace, therefore the aperture of door and window has multistage adjustablely with regard to corresponding, has solved window catch and can't realize the defective that aperture is regulated.But window catch might as well, wind brace might as well, it all is the structure that is installed in the door and window below, needs artificial hook, not only diminish the integrated beauty of door and window, increased the trouble that door and window cleans, if in time do not place wind brace after using, will cause stretching into indoor parts and bump the people and hinder drawbacks such as thing, for example the clothes of hook holdings, damage child's head therefore neither ideal structure.

The purpose of this utility model is to overcome the defective of prior art and provides a kind of hiding not need artificial hook in door window frame, can reach the automatic positioning and wind preventing device of door and window that the door and window aperture is regulated purpose arbitrarily.

The purpose of this utility model be achieved in that it by strut, help support, sliding axle, constitute with the tooth plate of the slide plate of two chutes, band positioning tooth, torsion spring etc.The elastic force that utilizes torsion spring to act on the spring detent of tooth plate two ends tightly is engaged on the positioning tooth of tooth plate sliding axle, thereby the door and window of unlatching is positioned on the desired aperture position automatically.

One end of this wind-proof device can be fixed on arbitrarily in the upper and lower, left and right framework of door and window, other end respective fixation is above or below sash, strut constitutes " people " font articulated support structure with helping support during unlatching, is folded into " one " font when closing and hides in door and window upper frame or underframe.

The utility model is compared with known technology, because it is hidden and does not expose, can not find its trace after the door and window closure, not only avoided the strut hook to draw pedestrian's clothes and the drawback of the child's head of damaging, make door and window have more integrated beauty simultaneously, this wind-proof device is simple in structure, implements easily, the location is reliable, open and close flexiblely, can alleviate the impact force of strong wind, avoid the door and window sharp impacts and damage glass, it does not need artificial hook, can reach any adjusting aperture purpose by the slide door or window handle.

Description of drawings.

Fig. 1 is the utility model structural representation.

Fig. 2 is № 7 tooth plate structure charts.

At above-mentioned accompanying drawing embodiment, will describe in further detail below.

Each of the automatic positioning and wind preventing device of door and window (seeing Fig. 1-2) in addition part with certain thickness steel plate punching technological forming, last or the lower frame of its strut (5) one ends and door and window is fixed, center with help support (6) hinged, help the other end and slide plate (1) one end of support (6) hinged, have two chutes different in size (2) on the slide plate (1), slide plate (1) can slide relatively with tooth plate (7) and mutual closed assembly, and tooth plate (7) has positioning tooth (3) structure.The other end of strut (5) is fixed a sliding axle (4), and it passes the chute (2) of slide plate (1) and the teeth groove (11) of tooth plate (7) is riveted one with the slide plate (1) and the tooth plate (7) of mutual closed assembly, and sliding axle (4) can slippage in above-mentioned groove.

Tooth plate (7) two ends also have slotted hole (10) and spring detent (12) structure, tooth plate (7) is connected in the door window frame with screw (9), this screw (9) passes the chute (2) of slide plate (1) and the slotted hole (10) of tooth plate (7), torsion spring (8) is sleeved on the screw (9), one end snaps in the line of rabbet joint of spring detent (12), one end acts on the door window frame sidewall, make positioning tooth (3) on the tooth plate (7) be subjected to torsion spring (8) elastic force impetus and tightly mesh, thereby door and window is positioned on the desired aperture position automatically with sliding axle (4).

The design of tooth plate (7) slotted hole (10) is in order to make it have certain longitudinal oscillation scope, thus when the hand push door and window, sliding axle (10) just can cross positioning tooth (3) and carry out opening angle and regulate, hand one loosen promptly be engaged again and automatically the location live.

Door and window at opening-closing process middle slide plate (1) along chute (2) axial slip, make strut (5) and help support (6) or be launched into " people " font and support or be folded into " one " font and draw in, when being launched into " people " font, door and window is in opening, when being folded into " one " font, door and window is in closure state.In order to make strut (5), to help the folding back of support (6) to become " one " font with slide plate (1), must meet following condition: ab+bc＜L, L is long chute (a 2) length in the formula, it is definite strut (5) and extended length that helps support (6) and sliding distance, and short groove (2) is control slide plate (1) tooth plate (a 7) displacement relatively.

The utility model can be installed in the closure place of the left and right symmetric position of the upper and lower framework of door and window, with the passing of time sagging and cause that wind-proof device blocks for fear of door and window, generally to be installed in the door and window upper frame as good, make simultaneously the limit, lower end of door and window not have the supporting construction of getting in the way, not only attractive in appearance but also be convenient to clean door and window, be placed on being also advantageous in that of upper frame and drench less than rainwater, can not get rusty, prolonged service life.
