From the locked position, the opening is substantially flush with the locking edge away from the leading locking recess. flexibly slidable to a released position aligned with the opening in the system. Adopting these characteristics In the structure used, the locking latch includes a trailing cam surface aligned with the leading cam surface; forming an edge of the leading locking recess and a trailing locking recess spaced apart from the leading locking recess; This allows the locking edge of the retaining plate to jump over both of the above cam surfaces and into the subsequent locking recess. As a result of being engaged, the opening/closing frame is locked in a slightly open position relative to the fixed frame. do.

Preferably the retaining plate is arranged in an overlapping relationship with the guide plate and is slidable. The movable plate is supported by the guide plate during sliding movement, and the guide plate is It has a hole that aligns with a frame opening that is sized to receive a locking latch.

The locking release means engages or releases each locking recess provided in the fixed latch and the locking edge. Includes a portion of the retaining plate that allows manual operation.

Another feature of the invention is a glass panel assembly including a fixed frame and a retractable frame. For solids, the hook is to provide the whole device, and the device is fixed to the opening and closing frame. A portion of the locking latch extends when the opening/closing frame approaches the closed position. An opening in the fixed frame and a fixed latch automatically in one of two different positions. Open and close the frame against the fixed frame by engaging the closed position or slightly A movable locking means provided on the fixed frame for locking in the open position; It includes a locking means and a disengaging means for disengaging the locking latch.

Still another object of the present invention is to provide a glass panel assembly including a fixed frame and an opening/closing frame. Attach the opening/closing frame to the fixed frame in the closed or slightly open position relative to the solid. The automatic locking device is to provide a locking device, and the locking of both frames is provided by a fixed frame.

The fixing latch 16 is formed from a T-shaped mvi, and the T-cedar board is attached to the frame. Depending on the contour of the drum, it may be straight or bent like a crank in the middle of both ends. T The head of the shape clip is fixed to the side end surface 14a of the opening/closing frame with a suitable tightening material 18. When attached, the free tip of the IT-shaped stem bulges out from the frame periphery and becomes rigid. Projects toward the fixed frame. Adjacent to the free distal portion of the stem, the upper edge thereof is Two teeth spaced apart by a tooth 24 having a rear beveled cam surface 24a. A locking recess 20.22 is formed. Similarly, the tip of the stem has a rake angle at the rear. A leading tooth 26 is formed with a cam surface 26a. Thus, the leading locking recess 20 is As shown in the side view of FIG. 4, it is partially defined by the cam surface 24a and has a generally V shape. The trailing locking recess 22, on the other hand, has a U-shape.

The retaining assembly is located on the side of the fixed frame facing away from the latch, i.e. inside the building. It includes an elongated guide plate 28 adapted to be clamped to the peripheral surface 12b of the frame. When the guide plate is tightened to the fixed frame, the hole 30 is inserted into the fixed frame 12. guide a longitudinal hole 30 suitably positioned to align with an aperture 32 formed therein; Form into a plate. When the opening/closing frame 14 is closed or slightly opened, the opening 32 is positioned to receive latch 16. The guide plate 28 is a spaced apart guide. a guide plate including inverted elongated side flanges forming grooves 34 and 36, respectively; The hole is repositioned at the top and bottom, and the bottom hole 38 is opened as shown in FIG. receives the fastener 40, so that the guide plate is fixed to the fixed frame. hippopotamus -42 is snapped onto the periphery of the guide plate.

The guide plate has opposing side edges 50.52 respectively received in guide grooves 34.36. The retaining plate 48 receives a displaceable retaining plate 48 so that the retaining plate It is slidable in a direction vertically opposite to the rate. The retaining plate is a thin perforated It includes a long portion P, which typically extends beyond the tip of the guide plate, and which covers the cover 42. It passes through an opening 54 formed in a wall 56 at the distal end of the tube. For hole S, the holding plate is fastener 4. Allows movement relative to 0. The elongated portion terminates in an upwardly directed lip 60, which The retaining plate can be operated manually by means of the lip. The holding plate is a guide plate In contrast, the lip 60 (as shown in FIGS. 2 and 4) is attached to the tip wall 5 of the cover 42. 6 to a unlocked position where the lip 60 is adjacent to the tip wall 56. move. When the retaining plate is in the released position, the hole 30 in the guide plate and the fixing plate are A hole 62 is formed in the retaining plate that aligns with the opening 32 in the frame. However, hole 62 The holes 30 and openings 32 are partially maintained when the retaining plate is in the locked position. As a result of the arrangement, the locking edge 64 of the hole 62 is located in the leading locking recess 20 or the trailing locking recess 2. It can be congruent with either of 2. The retaining plate connects the tip remote from the lip 60 with the retaining plate. A leaf spring 66 provided on the guide plate locks the plate between the adjacent tips of the plate and the locking position. is flexibly pressed.

The cover 42 has a gap in which the fixing latch engages and locks with the holding plate, and the fixing latch 16 providing a housing for the leading edge of the housing.

To lock the locking frame in the fully closed or slightly open position: , freeing the stem of the fixed latch by pivoting the opening and closing frame to the closed position The end passes through the opening 32 in the fixed frame and the hole 30 in the guide plate, thereby Leading cam surface 26a engages locking lip 64. Successive closing movement of the opening/closing frame In response, the retaining plate is displaced upwardly against the pressure of the spring to open the hole 62 in the opening 32. , aligned with hole 30 so that the free end of the latch passes through the retaining plate. leading When the cam surface 26a passes over the locking edge 64, the retaining plate springs into the locked position. so that the locking edge 64 of the retaining plate is pulled back into the V-shaped leading locking recess 2 of the latch. engages with 0. In this way, the opening/closing frame is positioned slightly open from the fixed frame. to lock automatically. Further closing movement of the opening/closing frame causes the trailing cam surface 24 a engages with the locking edge 64 of the holding plate, and the locking edge 64 goes over the cam surface 24a. Then, the holding plate is again displaced upward to the release position against the pressure of the spring 66. . Once the latch stem has fully penetrated, the retaining plate will spring back into the locked position. so that the locking edge of the retaining plate engages in the U-shaped subsequent locking recess 22 of the fixed latch. be done. The opening/closing frame is thus automatically moved in the fully closed position relative to the fixed frame. to be locked.

The opening/closing frame is locked in a slightly open position from the fully closed position, that is, the so-called If you want to place it in the night ventilation position, simply press the lip 60 and manually lift the retaining plate upwards. Therefore, the locking edge 64 should be moved beyond the teeth 24 and the cam surface 24a. It can now be placed again in the shaped locking recess 20. Apply opening force to the opening/closing frame This may also be necessary for many window frame assemblies, especially those made of plastic materials. , surrounds the opening of the fixed frame and opens and closes with the fixed frame when the opening/closing frame is closed. The sealing member inserted between the frames opens and closes when the retaining plate is in the release position. Provides sufficient flexibility to automatically displace the frame to a slightly open position. opening and closing Move the frame to a position where it can be opened and closed so that the frame is not locked to the fixed frame. In order to It is natural to operate or hold the
