Abstract

The utility model discloses a small opening locating sliding door or window. The lower end of the other side of a locking switch of a sliding door leaf or a window sash is provided with a bolt device. When the sliding door leaf or the window sash is in a small opening position (The opening slot that the arm of a human body does not extend into is standard.) or in the closed position, a hole where a bolt rod is inserted is arranged in the corresponding position of a door frame or a window frame. The bolt rod is inserted into the hole when the door or the window is in the small opening position or in the closed position. In this way, when the door or the window is in the small opening position and the bolt device is locked, and because the arm of the human body can not extend into the slot, the utility model has the protecting function when ventilation; when the door or the window is closed, except that the original switch is locked, a user can also lock the bolt device, and the utility model has double protecting functions.

Description

Small-opening limited sliding door and window

The utility model relates to a kind of small-opening limited sliding door and window of building doors and windows technical field.

General slide door or window is only locking when closing usually, in case just be in free state after opening, wish that for the user door and window had both had little aperture unlatching and carried out ventilation, the dual-use function that again can be effectively the sliding door window sash locking be played protective action is difficult to realize, and the intensity of the locking device of existing common slide door or window when closing is often on the low side.

The purpose of this utility model just provide a kind of both can little aperture ventilation, can lock the slide door or window of protection again, and when door and window is closed, strengthen safeguard function.

The utility model is to realize like this, a bolt device is installed in opposite side lower end at the sliding door window sash locking switch, when bar be in little aperture (with human arm can not stretch into bar crack be as the criterion) or during fastening position, on doorframe and window frame position correspondingly, open the hole that a bolt rod inserts, when door leaf is in little aperture or cuts out, the bolt rod insertion both can.Like this, when the locking of little aperture bolt device, crack,, when bar is closed,, also bolt device can be locked, play the double protection effect except that original switch rises the locking action so play protective action during ventilation because of human arm can not stretch into.

Below in conjunction with accompanying drawing preferred implementation of the present utility model is specifically described:

Fig. 1 is the full figure that adopts the sliding sash of bolt device.

Fig. 2 adopts the part of the aluminium matter sliding sash of bolt device to amplify schematic perspective view.

Fig. 3 is the plastic sliding sash schematic perspective view that adopts bolt device.

Fig. 4 is the internal construction schematic diagram of bolt device.

As shown in Figure 1,1 is push-pull window frame, and 2 is the sliding window sash of right side closed condition, and 3 for the left side is in the sliding window sash of little aperture opening, and 4 is the switching device of sash, and 5 is bolt device.Right side sash 3 is on little aperture position among Fig. 1, and the bolt device 5 of its lower end, right side is in the lock state.Shown in Figure 26 is aluminium matter push-pull window frame, 7 is aluminium matter sliding window sash, 8 is the bolt rod in the bolt device, when bolt rod 8 inserts little aperture location in the hole 9 of window frame 6 relevant positions, form little aperture location, deviate from then bar when inserted link 8 and can be free to slide and open or close, 10 inserted links of latch when cutting out for sash 8 insert the hole of locking usefulness.After door and window was closed locking, pin rod 8 inserted in the hole 10, the barrier propterty when closing to strengthen door and window.Figure 3 shows that the schematic perspective view of the plastic sliding sash that adopts bolt device.Wherein 11 is window frame, and 12 is sash, and 13 is the button in the bolt device.Fig. 4 is the cut-away view of bolt device, can make bolt rod 8 that certain elastic force pressure is arranged by this structure spring 14, push button after 13, spring 14 makes under bolt rod 8 bullets, in the door and window motion, insert the hole locking of doorframe and window frame location automatically, after bolt rod is mentioned, also can utilize buckle 15 fastenings, not influence the unlatching operation of bar.

The foregoing description is only for preferably a kind of, in fact utilizes multi-form bolt device all can realize little aperture location and locking when closing.On the slide door or window of unlike materials such as this mode can be applicable to steel, aluminium after changing a little, mould and different structure.That is to say that the little aperture locking of the sliding sash made from above-mentioned basic mode increases locking and has various deformation and improvement with closing, and all should be considered as in protection domain of the present utility model.And small-opening limited sliding door and window not only can be used in the production of new door and window, can also be applied to old building slide door or window is transformed into small-opening limited sliding door and window.
