Abstract

The utility model is used for steel windows and can also be used for a door-window type device needing regulated sizes of opening. People just lightly exert on a sliding frame (2) or a handle (3) to make the sliding frame (2) move from right to left on a rack gear (1) so as to regulate the opening size. When the hand leaves the sliding frame (2) or the handle (3), the sliding frame (2) can not move from right to left, and therefore, the opening size of the window is fixed. Compared with the existing gong pins type locking device, the utility model has the advantages of convenient operation, non-perishable damage property and effective locking.

Description

Automatic locking device for opening window sash at arbitrary angle

The utility model is applicable to steel sash, also is applicable to the door and window formula device that needs to regulate aperture.

Existing steel sash aperture locking: a kind of is in advance several aperture shelves to be set on the support bar or on the fixed slip bar, and this does not reach the purpose of any aperture undoubtedly.Another kind is when making support bar that window is reached predetermined aperture, again the gong bolt on the slider bar is screwed and realize locking: and will readjust the aperture of window the time, must earlier the gong nail be unscrewed again, support bar is opened window to required aperture, also the gong nail must be screwed then and realize locking: this makes windows, and closing window becomes comparatively complicated process, and the gong nail is after certain hour simultaneously, also can produce the accident that collapses silk or twist into two parts, the result can not lock window.

At this defective, the purpose of this utility model is a kind of window can being opened to any aperture of design, need only leave by hand one, just the device that can automatically lock.

The utility model realizes that the method for above-mentioned task is: the fixed slip bar that is fixed in window frame is the toothed tooth bar of a side, with slider bar that support bar links to each other on, a bayonet lock that matches with the teeth of tooth bar is arranged, bayonet lock is because the effect of spring or gravity, when not having external force, be stuck in the teeth of tooth bar, slider bar can not be moved arbitrarily, thereby make the aperture locking of window.When the handle of slider bar or bayonet lock is subjected to external force, bayonet lock withdraws from the teeth of tooth bar, slider bar just can be slided arbitrarily, the aperture of window also changes therefore and arbitrarily, when the power that imposes on slider bar or bayonet lock handle disappears, bayonet lock is because the effect of spring or gravity is stuck in the teeth of tooth bar again, and the aperture of window realizes locking because of slider bar can not move arbitrarily.

The utility model has tangible advantage and positive effect compared with the prior art: at first be that the locking of any aperture of steel sash is oversimplified from comparatively complicated process, become once and finish; Next is that locking effect is good, even window is when being subjected to bigger external force, also is difficult for producing displacement; The 3rd is not fragile, and simple in structure, and cost is low, is convenient to make.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is an elevation of the present utility model;

Fig. 2 is a vertical view of the present utility model;

Fig. 3 is the profile of tooth bar;

Fig. 4 is the sectional drawing of the utility model along Fig. 2 I-I line.

Fig. 1 is an elevation of the present utility model: (1) is tooth bar, and (2) are slider bar, and (3) are handle, and (4) are the stationary rack frame, and (5) are handle groove.

Fig. 2 is a vertical view of the present utility model: (1) is tooth bar, and (2) are slider bar, and (3) are handle, and (4) are the stationary rack frame, and (6) are support bar.

Fig. 3 is that the profile of tooth bar (1): A, B, C, D are multi-form tooth bar, and (7) are the teeth of tooth bar.

Fig. 4 is the sectional drawing of the utility model along Fig. 2 I-I line: (1) is tooth bar, and (2) are slider bar, and (3) are handle, and (7) are teeth, and (8) are bayonet lock, and (9) are the locking spring, and (10) are the movable axis of bayonet lock (8).The locking spring (9) of E figure with the light pressure of handle (3), can make the teeth (7) of bayonet lock (8) disengaging tooth bar (1), so slider bar (2) can be slided along tooth bar (1) downwards below bayonet lock (8).The handle of F figure (3) is heavier, sinks naturally when having external force and bayonet lock (8) is risen block the teeth of tooth bar (1), thereby saved locking spring (9), and handle (3) is upwards lifted, and slider bar (2) is slided along tooth bar (1).The bayonet lock of G figure (8) is the bottom that is fixed on slider bar (2), locking spring (9) is between the top of the top of tooth bar (1) and slider bar (2), put forth effort on slider bar (2), compressing locking spring (9) makes it to shrink, bayonet lock (8) moves down the teeth (7) that break away from tooth bar (1) with slider bar (2), and slider bar just can be slided along tooth bar.

Embodiment of the present utility model: because support bar (6) other end that links to each other with slider bar (2) links to each other with window, change the angle between support bar (6) and tooth bar (1), the aperture of window also changes thereupon.Handle (3) to slider bar (2) or bayonet lock (8) is exerted oneself slightly, make bayonet lock (8) break away from the teeth (7) of tooth bar (1), slider bar (2) is horizontally slipped along tooth bar (1), angle between support bar (6) and tooth bar (1) becomes big or diminishes, and the aperture of window also becomes big thereupon or diminishes.When reaching to required aperture, hand is removed the handle (3) of slider bar (2) or bayonet lock (8), bayonet lock (8) reenters the teeth (7) of tooth bar (1), slider bar (2) just can not move along tooth bar (1), tooth bar (1) is fixed with the angle of support bar (6), and the aperture of window is also therefore locked.

Claims

1, any aperture automatic locking apparatus of steel sash has support bar, fixed slip bar, slider bar, it is characterized in that: fixed slip bar is the tooth bar (1) that a side has teeth (7), and a bayonet lock (8) that matches with the teeth (7) of tooth bar (1) is arranged on slider bar (2).

2, any aperture automatic locking apparatus of steel sash according to claim 1, it is characterized in that: bayonet lock (8) has one handle (3), and bayonet lock (8) links to each other with slider bar (2) by turning cylinder (10).

3, any aperture automatic locking apparatus of steel sash according to claim 1 is characterized in that: a locking spring (9) is arranged between bayonet lock (8) and slider bar (2).
