DETAILED DESCRIPTION OF THE INVENTION The present invention is a pushing device for a window or door having a shoji that is pivotable about a vertical axis and tiltable about a horizontal axis, the push-out arm facing the window frame. This invention relates to a type in which a pivot support for a lever mechanism is disposed at the end and an adjustment device is provided within a case for the lever mechanism that can be fixed in position on the shoji frame side.

SUMMARY OF THE INVENTION The object of the invention is to improve an extrusion device of the type mentioned above so that its assembly and installation can be carried out quickly and easily.

In the configuration means of the present invention for solving this problem, the pivot support part is configured in a chevron shape and has a vertical leg piece and a horizontal leg piece, and the vertical leg piece is connected to the pivot support part of the vertical frame of the window frame. The horizontal leg piece is configured to be inserted into a groove formed in a C-shaped cross section on the side and has an undercut portion supported on the inside of a chevron web forming a part of the groove, and the horizontal leg piece It is configured to be fixed to a slider that can be positioned in an anchor groove provided in the upper frame of the frame, and the slider has an integrally molded protrusion on one end surface, and the protrusion is connected to the slider. In the attached state, the child is supported by abutting against one web of an adjacent vertical frame of the window frame.

In short, the slides are received by anchor grooves in the horizontal upper frame of the window frame and are fixed to said upper frame of the window frame by means of screws. Before fixing the position of the slide, the projection is shifted along one web of the vertical frame of the window frame, so that a correction of the slide is carried out at the upper corner corner of the window frame. When installing a chevron-shaped pivot support for a lever mechanism, the vertical leg piece is first inserted into a C-shaped groove provided in the vertical frame of the window frame.
It occupies the position shown in FIG. The pivot support is then guided upward until its horizontal leg abuts the slider, and after the contact, the horizontal leg of the pivot support is screwed to the slider. Therefore, while the pivot support part in the lever mechanism is fixed in position on the slider, the pivot support part is moved to the upper part of the window frame by engaging the vertical leg piece having the undercut part with the chevron web of the vertical frame. It locks perfectly in the corners.
Further, since the pivot support portion only needs to be fixed to the slider with a few screws, assembly and installation are extremely simple.

The length of the integrally molded projection is selected in such a way that the pivot bearing can be screwed onto the slider with the projection in contact with one web of the adjacent vertical frame, in which case the additional This simplifies assembly, since no manual reorientation is required.

Furthermore, in a preferred embodiment of the invention, the adjustment device comprises:
a holding piece that is slidable in the longitudinal direction of the case within the lever mechanism case and that can be fixed in position to the shoji frame; and a holding piece that is rotatably arranged within the lever mechanism case and that holds the holding piece at a plurality of locking positions. It consists of an eccentric pin which is engaged with the holding piece and which is fitted into the hole of the retaining piece with a pin that is eccentrically arranged with respect to its axis of rotation.

If the adjustment device is configured in this way, the adjustment of the window or door shoji can be carried out very quickly and easily. This is because the eccentric pin only needs to be rotated into another locking position in order to selectively raise or lower the shoji as required. In that case, the adjustment device allows the shoji to be raised or lowered by 1 to 2 mm. By rotating the eccentric pin, the position of the lever mechanism case with respect to the holding piece and thus the shoji stile is changed, and therefore the position of the link pivot point with respect to the shoji stile is also changed.

Next, embodiments of the present invention will be explained in detail with reference to the drawings.

The extrusion device shown in FIGS. 1 and 2 has an extrusion arm 1, and a pivot support 2 is attached to a pivot pin 3 at the end of the extrusion arm on the vertical frame side. The swing support part 2 is connected to the slider 5 by two screws 4.
The slider 5 can be fixed in position by a set screw 6 in an anchor groove in the upper frame of the window frame. As can be seen from FIG. 2, the slider 5 has a projection 7 integrally formed on one end surface, which is supported by abutting against the web of the vertical frame 8 of the window frame when the slider 5 is assembled. . The length of the projection 7 is chosen to ensure the correct assembly position of the slide 5 when said projection 7 abuts one web of the frame 8.

The swivel bearing 2 has a vertical leg 9, which has an undercut 10, which in the assembled state, as can be seen in FIG. Engage backwards. The position of the swing support part 2 is fixed to the slider 5 by the screw 4, and the undercut part 10 of the vertical leg piece 9 and the vertical frame 8 are fixed.
By engaging the chevron web 11 of the swivel bearing 2, the swivel bearing 2 is securely fixed in all directions in a simple manner. There is no need for direction correction work to assemble the swing bearing 2.

In short, the extrusion device of the present invention, which mainly includes the extrusion arm 1, the link 13, and the lever mechanism case 12, is arranged between the horizontal upper frame of a fixed window frame and the horizontal upper frame of a shoji frame. The lever mechanism case 12 is fixed in position to the upper frame of the shoji frame via the holding piece 15. To fix this position, the lever housing 12 can be shifted axially relative to the retaining piece 15 by means of the adjusting device 14 with the eccentric pin 16 before it is fixed.

The tilting of the shoji of a window or door is carried out by pivoting about the lower horizontal axis of the shoji, and the shoji is kept in the tilted position by the push-out arm 1, in which case the push-out arm 1 is moved against the window frame. It is pivotally mounted by a pivot bearing 2, which has a pivot pin 3. This pivot pin 3 forms an upper pivot support for the shoji. The shoji is brought into a pivoting position by setting the operating grip in place, in which the shoji is moved into an open position about a vertical pivot axis defined by a pivot pin.

A correction of the shoji relative to the window frame is effected by an adjustment device that changes the relative position of the shoji relative to the window frame.

The end of the push-out arm 1 remote from the pivot support 2 is slidably supported by a lever mechanism case 12 fixed to the horizontal upper frame of the shoji frame. A link 13 is pivotally connected to the other end of the lever mechanism case 12, and the other end of the link is pivotally connected to the push-out arm 1.

An adjustment device 14 is disposed within the lever mechanism case 12, and the adjustment device mainly includes a holding piece 15 and an eccentric pin 16.

The holding piece 15 shown in FIGS. 7 to 9 is a fixing screw 1 having a pin 18 that can be inserted into a hole in a window sill.
7, it is fixed to the shoji frame so that it cannot move relative to the shoji frame. The lever mechanism case 12 can be moved in the axial direction with respect to the holding piece 15. The eccentric pin 16 shown in FIGS. 3 to 6 is rotatably supported in a hole in the lever mechanism case 12. A pin 19 arranged eccentrically with respect to the rotational axis of the eccentric pin 16 is fitted into a hole 20 (FIG. 8) of the holding piece 15. In the peripheral area of the hole 20 the holding piece 15
has a predetermined number of locking grooves 21, into which a correspondingly shaped locking protrusion 22 of the eccentric pin 16 can engage. As can be seen from FIG. 2, the eccentric pin 16 is connected to the holding piece 15 by a disc spring 23, so that the locking protrusion 22 of the eccentric pin 16 is always directed toward the locking groove 21 of the holding piece 15. It's starting to feel like pressure. That is, the disc spring 23 is disposed between the eccentric pin 16 and the holding piece 15 and is configured to allow the pressing stroke of the eccentric pin 16 against the holding piece 15 by at least the height of the locking protrusion 22. This makes it possible to rotate the eccentric pin and to lock the retaining piece in another locking groove.

The locking groove 21 and the locking protrusion 22 are shown in FIGS. 6 and 9.
As can be seen, it has an approximately semicircular cross section. By giving such a shape, the eccentric pin 16
can be pivoted into another locking position without the need for any special lifting of the eccentric pin. That is,
This is because when the eccentric pin 16 rotates, the locking protrusion 22 is pushed out of the locking groove 21 in which it has been locked.

The head end of the eccentric pin 16, which projects from the lever mechanism case 12, has a hexagonal edge 24, which makes it possible to rotate the eccentric pin 16 using a spanner.
