Plastic window malfunction handle
Owners of plastic windows over time face some problems associated with the repair or replacement of hardware. Handles for windows, can be called a "weak link" in the overall design.
The arising problems can be connected with such circumstances:
• defects and wear of the handle of the blocker
• Improper use of fittings
• mechanical damage.
The procedure for replacing the handle for the window is simple and you can do it yourself.
But the current repair will depend on the cause that caused the malfunction. For repair or replacement, you need to know which brands are installed accessories on the window of your apartment and the design of the window handle.
Window handle design
Thanks to a well-thought-out design, the handle of the plastic window ensures the position and movement of the window flaps.
The main provisions of the window wings are:
• Open mode
• closed mode
• microvolving.
Externally, the handle is a monolithic mobile structure with a decorative coating and a rod of a square cross-section at the other end. The principle of the handle is as follows: when the handle is rotated, the transmission bus starts to move.
This is an internal steel plate with a trunnion, wound up for an offshoot. In certain places of the transmission bus, there are protruding elements with which the door is locked or opened. When you turn the window handle pivots move. The position of the trunnions behind the counter strips, which are mounted on the impost or frame, provides a dense attraction of the wings to the frame.
The handle is located down - the position is "closed". When the handle is rotated through an angle of 90 degrees, the trunnions exit the counter strips, the sash of the window opens. The horizontal position of the window handle is the "open" position.
When you turn the window handle up, the hardware switches to the "microvolving" mode. This position with the help of control of the handle is achieved due to the removal of the trunnions from the return bars, except for the lowest trunnion.
The micro-ventilation mode also provides a spring-loaded hinged closure. Thus, the role of the window handle in the operability of the window system can be called in the direct and figurative sense - the guide. When used correctly, the window handle serves a long time. However, for a number of reasons, the following unforeseen circumstances may arise:
• the handle does not turn completely and jams
• the handle of the plastic window does not close and does not open
• jammed the handle of the plastic window
• the handle has broken and needs to be replaced.
How to deal with unpleasant situations - to call a master or repair or replace the handle of the window with your own hands?
Major emergency situations and what needs to be done
In the emergency case, when the handle of the plastic window is in an inoperative state, the first thing to do is remove the handle from the window.
the handle does not turn completely and jams
If the window handle does not turn completely and jams, the cause must be sought in the sagging of the window leaflets and the lack of proper lubrication of the handle mechanism.
Controlling a significant number of transfer mechanisms of the window system is carried out by a single handle. Therefore, good work will be guaranteed by lubrication and cleanliness of the working units.
To remove rubbing surfaces, WD-40 grease should be preferred. The mobile elements and the connections of the locking mechanism are treated with lubricant.
jammed the handle of the plastic window
This situation is most common and is associated with the incorrect operation of the turn blocking device. The turn blocking device is equipped with all plastic windows produced by the manufacturer. The turn blocking device prevents the window leaf from closing until the locking tab is in the extended position.
The steel tongue or the tilting device is in working condition with respect to the window frame at an angle.
Incorrect operation of the lock can unpredictably lock the handle in any position. What should be done in this case? Learn the brand of installed hardware. The name of the brand can be found on a metal locking plate. If the accessories of stamps "Roto", "Winkhaus", "GU", then in this case, you need to press the locking tongue inward with your finger until it returns to the vertical position.
Now it will be possible to turn the handle and close the window. At fittings of other brands, namely AUBI or MACO, instead of a steel tongue there can be a thin plate with a spring. The plate is also pressed with a finger and pressed, and the window is closed by turning the handle.
It does not hurt to check if the blocker with the reciprocal mechanism is in contact correctly.
Such malfunctions may appear after prolonged thermal expansion or compression. We find the reciprocal element of the blocker on the frame and achieve full grip on the location. For these purposes, you can use a plastic lining.
the handle has broken and needs replacement
In the case where the window handle scrolls without a distinctive sound and does not open the sash of the window, the cause of the malfunction may be the fall of the steel rod. In this case, the lid cover, located at the base of the handle, must be pinched by two fingers, pull on and rotate by 90 degrees.
Unscrew the fixing screws and remove the handle. Pull out the "problem" rod with pliers. Then install the square bar back into the handle and securely fix it in place. Replace the handle in the handle downward.
If the plastic case of the window handle has become unusable, you must first purchase a new handle. Handle for plastic windows to buy is preferable to the brand, which was installed before the repair.
We remove the old handle. For this, the vertical plastic cover is turned to the horizontal position. We turn away the fastening elements and remove the handle. We install a new window handle in the hole and fix it with the help of fasteners. We check the efficiency of the new pen.
