Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a swinging and tilting casement window that can be turned about a vertical axis and tilted about a horizontal axis, and has a drive rod fitting, and the drive rod fitting is similar to a shoji screen. It consists of a handle supported on the vertical vertical members of the frame and at least two drive rods operated by the handle, the drive rods being connected to the vertical vertical members on the handle side of the shoji frame and the horizontal upper cross members. is slidably guided in the window frame and has a tilt stop bar, one end of which is pivotally supported on a pin fixed to the window frame and forming an upper pivot bearing. The present invention relates to a type in which the other end of the tilt stopper bar is engaged via a pin into an elongated hole of a bridge member fixed to the upper cross member of the shoji frame.

In a swing-and-tilt casement window of the type described above, the shoji is tilted from the window frame plane into the tilt-open position insofar as the only handle, and thus the drive rod operable via the handle, is moved into the tilt-open position. . During this tilting/opening movement, it can be braked by the hand grasping the shoji handle, but generally after the handle is moved to the tilting/opening position, the tilting movement of the shoji is further accelerated by the tensile load on the handle.

Therefore, the tilting movement of the shoji to the tilted open position where the shoji is received and held places a high load on the metal fittings.

The object of the invention is to improve a swing-and-tilt casement window of the type mentioned at the outset, so that the shoji is continuously moved from the plane of the window frame into the tilt-open position during the tilt-opening process, and is prevented from tipping in an impactful manner. It is to be.

In order to solve the above problems, the present invention has the following features:
A guide piece is provided which is fixedly connected to the upper drive rod, the guide piece having a control cam which, during operation of the upper drive rod, moves the shoji frame between a closed position and a tilted open position. The guide piece is made of a plate, the control cam is made of a groove formed in the plate, and the groove is connected to the shoji frame. The one facing the handle side of the shoji frame is open, and the one facing the swivel support of the shoji frame is closed.

With the above-mentioned configuration of the present invention, the generation of impact forces that would overload the metal fitting member during the tilting-opening process is avoided, and the metal fitting can be operated carefully and the reliability of operation is increased.

Advantageous embodiments of the invention are defined in claim 2.
It is described below.

Next, embodiments of the present invention will be specifically described using the drawings.

As shown in the drawing, in a swinging and tilting casement window that can be rotated around a vertical axis and tilted around a horizontal axis, a drive rod fitting is supported by a handle 2 supported on a vertical vertical member 2 of a shoji frame and this handle. The drive rods are slidably guided in the vertical longitudinal members 2 and the horizontal upper cross members 4 of the shoji frame, and the drive rods are slidably guided on the upper handle side of the shoji frame. are connected to each other in the corner region via corner deflection elements (not shown). The drive rod 5, which is slidably guided in the horizontal upper crosspiece 4 of the shoji frame, carries a locking piece 6, preferably made of plastic, which locking piece 6 is connected to the tilting rod 8. The locking pin 7 is adapted to cooperate with the locking pin 7 of the drive rod fitting in the tilted open position.
engages the rear side of the As a result, in the pivoting position of the drive rod metal fitting, the tilt stop bar 8 is connected to the shoji frame near the upper pivot support portion 9 and is pivotally attached to the window frame 10. The tilt stop bar 8 is provided with a pin 11 at the end opposite to the pivot support part 9, and this pin is slidably guided in the elongated hole 12 of the bridge member 13, so that the bridge member 13 is attached to the shoji frame. is fixed to the horizontal upper crosspiece 4 of the drive rod 5 and surrounds the drive rod 5 at intervals. Furthermore, the tilt stop bar 8 has an additional arm 14, and this additional arm 1
4 is pivotally connected via a pin 15 to a bridge member 16, which is also fixed to the horizontal upper crosspiece 4 and surrounds the drive rod 5 at a distance.

The drive rod 5 is equipped with a guide piece 17, which in the illustrated embodiment is designed as a plate and has a control cam. Control cam is guide piece 1
7 is formed by a groove 18 which is closed in the opening direction of the tilting-opening process and open in the closing direction. A projection 19 engages in the groove 18 forming the control cam during the tilt-open movement of the shoji frame and during the return movement from the tilt-open position to the closed position. This projection 19 is configured as a cylindrical pin in the embodiment, and is arranged on the tilt stopper bar 8. In the embodiment, the protrusion 19 is offset with respect to the anti-tilt rod 8 and is fixed to a plate 20, which in turn is fixed to the anti-tilt rod 8.

Guide piece 17 and protrusion 1 when the shoji is closed
The location of 9 is shown in FIGS. 3, 4, and 7. The positions of the guide pieces 17 and projections 19 when the shoji frame is tilted and the shoji is opened are shown in FIGS. 5 and 6.

The groove 18 forming the control cam has an introduction opening 21 for the projection 19.

When the drive rod fitting (drive rod) is moved to the swing open position using the handle 1, the protrusion 19 is moved to the guide piece 1.
7, that is, separated from the groove 18, and finally the eighth
Occupy the position shown in the figure. In this position, the sash frame is pivoted about the vertical axis, and this pivoting movement is no longer blocked by the projections 19 and the guide pieces 17.

In order to make the guide piece 10 and the groove 18 relatively small in size and to obtain a sufficient opening angle of the shoji during the tilting and opening process, the guide piece 17 is connected to the horizontal upper crosspiece of the shoji frame and the tilting stop bar 8. is located on the drive rod 5 near its pivot point with the additional arm 14. The guide piece 17 may be located between the pivot point of the tilt stop bar 8 and the additional arm 14 and the pivot point of the additional arm and the crosspiece.
