Abstract

A pull buckle type window opening limiter is arranged at the inner side of a transverse window frame of an outer sash of a transverse pull type aluminum door window, and when a clamping block which can be movably accommodated in a containing chamber of a seat body is utilized to pull outwards, a side buckling piece is buckled on a buckling part arranged on the clamping block in a sliding way, so that the clamping block is in an outwards protruding locking stopping state, and the distance between the inner sash and the outer sash which can be opened is limited; when the function of the stop limit is to be released, the buckling piece beside the clamping block must be firstly slipped off the buckling part, so that the clamping block can be pulled to retract into the containing chamber of the base body, and the window sash can be restored to a completely opened state.

Description

Flip Window Opening Restrictor

technical field

The present invention relates to the design of a window opening limiter, which can be used to stop and control the openable width of the inner and outer window sashes when the pull-type locking block set by the limiter is pulled out. It is especially suitable for Horizontal pull aluminum doors and windows for security.

Background technique

In the design of the current building, in order to allow light and fresh air to enter the room from the outside, aluminum doors and windows are made on the walls of the building. However, in order to prevent thieves from invading after breaking the glass through aluminum doors and windows, and to make the sash more secure after opening, it is often necessary to install an iron window or aluminum grille outside the window for protection. Unauthorized opening of windows and falling accidents, but it also hinders the effect of real-time escape in the event of a fire. Iron windows or aluminum grilles will block the opportunity for firefighters to enter the fire scene to save people and fire; Due to the restrictions of the Building Appearance Maintenance Convention, it is also possible that the iron window fence cannot be installed on the outer window. Therefore, the user usually installs a detent limiter on the aluminum window to limit the opening distance of the inner and outer sash to prevent young children from The accident of falling from a building through an oversized window, such as the case of Taiwan Patent Publication No. I286586 "Aluminum Window Detent Positioning Limiter", mainly includes a body, at least one lock unit and at least one elastic catch block; wherein, a cavity is provided on the base to accommodate the elastic locking block, and the lock unit is provided on one side of the cavity, and the elastic locking block can be controlled to warp in the cavity by using the locking unit. It can be raised or retracted, and positioned; when the locking block is tilted up, the opening position of the horizontally pulled side-by-side sash can be restricted. In addition, when the locking block is retracted, the aluminum window can resume the normal full-opening function of the window sash.

However, when the catch block of this limiter is raised, it also forms a lock function. Although it can be used as a safety window to prevent children from climbing, it also has the effect of preservation, and when an emergency occurs, the catch can be released. The block is retracted into the chamber so that the window sash can be fully opened for use, but since the locking block is controlled by a lock unit, every time it is used, whether it is to make the locking block rise or retract, It is necessary to drive the lock unit with a key, which is quite inconvenient to use, and in order to prevent children from easily opening the lock unit, parents often store the key, but they cannot find it when an emergency occurs. key, so there are also security concerns.

In view of this, the inventor of the present invention has newly designed a window opening limiter that does not need to use a key to release the locking effect, and uses the buckle as a definite locking function, which is more convenient to use, and has both safety and security. Window opening restrictors with functions such as escape and anti-theft are provided for consumption by the public.
