Description

Push window opening limiter

The present invention relates to a push window opening limiter, and more particularly to a designer that can be used to limit the size of the opening window sash opening.

Pressing, the opening formed by the window sash of the window (opening) is slightly inadvertent, and the opening may cause an accident (such as a person falling outward); however, the conventional ejector window is not available. The mechanism for limiting the size of the opening of the sash is such that the ejector window, which does not limit the size of the sash opening opening mechanism, may be suspected of being safe and anti-theft.

The main purpose of the present invention is to provide a push window opening limiter with the effect of limiting the size of the opening window sash opening.

In order to achieve the above-mentioned effects, the structural features of the present invention include: a fixing frame formed with a limiting groove having an open end at one end and a window frame disposed at the push window; a latching mechanism for setting a housing The fixing frame has a projecting rod disposed on the casing and an ejecting rod control fastener is disposed, and a limiting fastener is disposed on the open end of the ejecting rod relative to the limiting slot, and the ejecting rod is used to control the fastener control The ejection lever is in a buckled state or a pop-up state, such that the restriction fastener is displaced at an unrestricted position away from the open end of the restriction slot and a restriction position close to the open end of the restriction slot; and a restriction lever, one end opposite the limit The open end of the slot is provided with a limit button and the limit end is pivoted on a movable frame, and the movable frame is disposed on the window sash of the push window.

In addition, the limiting fastener is formed with a restricted concave arc with respect to the open end, and a curved edge is further formed on the restricted concave side of the limiting fastener. Furthermore, the ejection rod is coupled with the elastic member for accumulating ejection power with respect to the housing, and the elastic member is a spring or a spring piece. In addition, the open end of the limiting groove is further formed into a bell mouth shape, and the other end of the restricting groove is closed end with respect to the open end.

First, referring to [Fig. 1] to [Fig. 3], the present invention includes: a fixing frame 10 formed with a restriction groove 11 having an open end 111 at one end and a closed end 112 at the other end, and further limiting the limit The opening end 111 of the slot 11 is formed in a bell mouth shape; a latching mechanism 20 is disposed on the mounting frame 10, and an ejection lever 22 is disposed in the housing 21 and an ejection lever control fastener is disposed. And a limiting fastener 24 is disposed on the open end 111 of the limiting rod 11 with respect to the opening end 111 of the limiting rod 11. The limiting fastening member 24 is formed with a limiting concave arc 241 relative to the opening end 111, and further to the limiting fastening member 24 The side of the concave arc 241 is formed with a curved edge 242. The elastic rod 22 is coupled with the elastic member (such as a spring or a spring piece, not shown) for accumulating ejection power, and the buckle is controlled by the ejection lever. The member 23 controls the ejection lever 22 to be in a buckled state or a pop-up state, such that the restriction fastener 24 is in an unrestricted position (as shown in FIG. 1) and away from the open end of the restriction slot 11 a restricted position of 111 (shown in Figures 2 and 3) is displaced; and a restraining rod 30 having one end opposite The opening end 111 of the limiting slot 11 and the limiting fastener 24 are provided with a limiting button 31, and the other end is pivotally mounted on a movable frame 40.

Based on the configuration of the present invention, please refer to FIG. 4 and FIG. 5 to illustrate the state in which the present invention is applied to the ejector window, and the holder 10 and the movable frame 40 are respectively disposed in the window frame of the ejector window. 50 and the sash 60; therefore, when the restricting fastener 24 is located close to the restricted end 111 of the restricting groove 11, the restricting button 31 of the restricting lever 30 is restricted by the restricting fastener 24 to restrict the concave arc 241. The lateral displacement, so that during the opening of the sash 60, the restriction rod 30 of the restriction state is only able to move longitudinally along the restriction groove 11, so that the size of the opening of the sash 60 is limited by the length of the restriction rod 30. Further, when the restriction fastener 24 is located at an unrestricted position away from the open end 111 of the restriction groove 11, the restriction button 31 of the restriction lever 30 is no longer limited by the restriction fastener 24 and can be laterally displaced. During the opening of the sash 60, the restriction bar 30 exhibiting an unrestricted state moves with the movable frame 40 disposed on the sash 60, and the sash 60 is restored to the state in which the original opening can be opened; however, when The limit bar 30 is changed from an unrestricted state to a limit a state in which the restriction fastener 24 is located at a position close to the open end 111 of the restriction groove 11, and when the restriction button 31 of the restriction lever 30 is engaged with the restriction fastener 24, the restriction button 31 is topped. The limiting buckle 24 is slightly retracted by the guiding edge 242 (because the elastic rod is coupled with the elastic member), and the limiting button 31 enters the position relative to the limiting concave arc 241, so that the limiting rod 30 The unrestricted state is changed to the restricted state.

Therefore, the present invention restricts whether the restriction button 31 of the restriction rod 30 is restricted by the restriction fastener 24 by the restriction of the restriction member 24 with respect to the opening end 111 of the restriction groove 11, and must be longitudinally along the restriction groove 11. The movement can be moved laterally. When the restriction button 31 can only move longitudinally, the length of the restriction rod 30 is limited by the opening size of the sash 60, and has the effect of limiting the size of the opening window of the sash window, and the lifting window is raised. Safety and anti-theft when opening windows.

In summary, the structure disclosed in the present invention is unprecedented, and can indeed achieve the improvement of efficacy, and has industrial availability, fully conforms to the new patent requirements, and prays for the patent to encourage innovation. There is no sense of morality.

However, the drawings and descriptions disclosed above are only preferred embodiments of the present invention, and those skilled in the art, which are subject to the spirit of the present invention, should be included in the scope of the patent application.
