"Closing and holding device for a pivotable one about a horizontal axis Window".

Priority: 3/20/1974 - SWEDEN

Windows that can be pivoted about a horizontal axis are often provided with a locking and holding device that a rod which is formed by a first short part which is attached to the window frame, and a much longer part, which adapts to the first part

is steered and is intended when it is about 90 ° pivoted with respect to the first-mentioned short part will, to keep the window closed, cooperate with a fixed stop on the window frame, and which further, when pivoted into alignment with the first part, is used to open the window in to keep various open positions.

The object of the invention is to create a closing and Holding device with improved properties. When the window is open, the bar is against a locking element pressed on the window frame by their own weight or by the action of a spring, so that it can easily be done that the rod is inadvertently disengaged from the locking element comes. If the rod is loaded by a spring to the window frame, a full opening of the window, by which the rod temporarily loses its contact with the window frame, the rod from the window frame pivoted down and out. When the window is closed is to be, the window frame is retained by the outside of the window frame so that it is easily deformed can be.

According to the invention it is now proposed that the stop be adjacent to arrange a channel-shaped fitting piece on the window frame so that it interacts with two walls, which are arranged at an angle to one another that a passage is obtained whose cross-section with corresponds to that of the longer part of the rod.

Some embodiments of the locking and holding devices according to the invention have been described below in connection with the The attached drawings are described in more detail and show:

A window locking and holding device of the type described here is particularly suitable for use with pivoting sash windows of the kind suitable that. are pivotable about a horizontal central axis, but can also with advantage Windows are used, which are arranged in vertical walls and / or which around hinges at their upper edge are pivotable.

Fig. 1 shows a pivoting sash window with a frame 10, which can be pivoted about a central axis 11 in a window frame 12. A window of this type is known per se and is therefore not described in more detail here.

The window can be held in a variety of different open positions by a rod IH with a Fitting piece 15 cooperates, which is attached to the window frame. However, it is believed that the window sometimes must be pivoted to a fully open position, on which occasion the rod is separated from the fitting must become.

According to one embodiment of the invention, the rod is loaded by a spring so that when it is out of engagement with the fitting, it is pivoted upwards towards the window pane into the position indicated by a dot-dash line 16. This prevents the rod from being wedged against the window frame when the window is closed.

The training of the Stanp "and the fitting piece are described below in connection with Fig. 2 - U described in more detail.

The rod consists of a shorter part 17 which is practically an arm and which is fastened to the frame 10 in a suitable manner is. A preferred type of attachment is described below in connection with FIG.

A much longer part 18 of the rod is hinged to the first part by a pin 19. That long part of the pole 18 serves as a lever when the window is closed and then interacts with a stop 20 on the window frame. Of the Stop 20 is arranged with respect to the contact surface between the frame and the window frame or to the pin 19, that the required closing force is obtained. In the closed position, the long rod part 18 held in the desired position by engaging a nose 21 on the window sill.

When the window is to be opened, the long rod part 18 is pivoted until it is with the short rod part 17 is in alignment, as shown by the dash-dotted lines -18a in Fig. 2, and then to it used to slide the window outwards / upwards.

The? Figure 3 is a largely conventional arrangement in which, as can be seen, part of the weight of the window rests on the bar. It is therefore important that the fitting on the window frame, which cooperates with the bar, is designed so that it prevents inadvertent loosening of the bar when the window is open.

The broom support 15 is designed as a U-shaped channel, das.jen web 22 is arranged perpendicular to the window frame. One of its side walls 2i is designed for attachment to the window frame and the stop 20 is arranged on this wall in such a way that it is parallel in the web 22.

In this embodiment it is not possible to use the rod in an arbitrary position, but it is determined in certain positions which are determined by the distances has been determined between the recesses 29, held. If the opening position is to be changed, the rod is lifted a little out of the window frame, see above that the piston 28 is moved to the wall 24 and a longitudinal displacement the rod allows.

The embodiment according to FIG. 6 is more or less one Inverse of that shown in FIG. The fitting piece has * as in the previously described embodiments, three walls 22, 2 3 and 24, but the stop is divided into parts 20a, 20b here, depending on whether the rod is pushed up by the holding device.

Extends through the lower side wall 23 of the Beschlapstücks a locking element 31 which is loaded by a spring 32 which is embedded in the window frame. The locking element 31 is actuated by an L-shaped element 3 3, which is held on the fitting by a pin 34, which cooperates with an elongated slot 35 in the L-shaped element.

With the help of the element 33, the locking device can optionally be pushed down when the rod is to be relocated. The rod part 18 is, as in the embodiment according to FIG. 5 is provided with a division which is formed by a series of recesses 29 in which the locking device engages. This embodiment is particularly safe when there is consideration for children must be taken, as a separate actuation requires a certain force to open the locking

509839/0360

Disengage the device and allow the rod to be moved.

As mentioned earlier, it is desirable that the rod is loaded in such a way that it is pivoted upwardly towards the window pane when it is out of engagement with the fitting is brought.

The shorter rod part and its attachment can preferably be of the type shown in FIG.

A plate 36 which can be attached to the frame is provided with two arms 37. The shorter rod part 17 is mounted in these arms by a pin 38. The pin 38 carries a spring 39, which is with her one End against the plate 36, while its other end acts against the shorter rod part 17.

This has the consequence that the rod is pivoted up to the window pane, as indicated at 16 in Fig. 1, as soon as the pole has come free from the bed. However, it is not desirable that the rod be fully against the disc rests, so it is preferable to provide some form of stop with limited movement the rod allows sufficient to prevent it from being pinched by the window frame when the window should be closed.

In the embodiment of the attachment shown in Fig. 8, the upper edge of the plate 36 is between the Arms 37 over the pin 38 to form a stop UO bent out, against which the rod part 17 comes to rest when the part 18 has been separated from the fitting is.
