Description

Bar fastener The present invention relates to a so-called so-called bar fastener Bar lock like this mainly for pivot windows, but also for other windows and can be used for doors.

Such a bar lock is known per se, but have There are various disadvantages to the bar locks on the market: In the corners of the window frame are either closed or closed open bar gaps and the bar ends slide on each other, which is at Temperature fluctuations can lead to difficulties and otherwise lubrication problems represents, since it is undesirable in and of itself, the touchable parts of the beam to lubricate. The bar fastener according to the present invention has all of these disadvantages Invention does not arise. Even with this one Lock is-every-thigh the window frame is provided with a bar running in the direction of the leg, which fence locking the closed wing in a groove in the wing frame can be inserted. The closure according to the invention is characterized in that that the four bars at their ends via angle levers rotatably mounted on the frame are interconnected and that one of these bars is connected to an actuator is in operative connection.

An embodiment of this invention is illustrated below with reference to described in the accompanying drawing.

In the drawing, FIG. 1 shows a view of the rotating window from the inside, FIG. 2 a section along the line II-IT with the lock closed, FIG. 3 shows a section along the line III-III. with the closure open, and FIG FIG. 4 shows the essential parts of the locking mechanism in a perspective view.

In the frame denoted by 1, the window sash 2 is on in a manner known per se, rotatably mounted about a vertical axis 3. For poetry Closing the window in the position in which the frame and sash frame lie in the same plane is the so-called bar, which is shown in Figures 2 and 3 is visible and denoted there by 4.

This beam 4 is attached to each of the frame ends on a carrier. Figure 4 shows how the carrier v and 6 of a frame corner with each other through a triangular intermediate member 7 are connected. This intermediate member 7 is at the mitt the Blendrairnien firmly connected axis 8 rotatably mounted.

Figure 4 shows the position of the parts with the base lock open, whereby. the arrows 9 indicate the direction in which the individual parts are when closing move so that the bars 4 reduce the opening of the window frame 1 and in the corresponding recesses of the sash 2 penetrate. As you can see from it can, the whole construction is structurally very simple construction with a few parts, dents a lever 10 which is rotatably mounted about an axis 11, serves as an actuator.

As a result, the entire window lock shows not just the one at the beginning mentioned disadvantage no longer has, but still has the essential one Advantage of a well thought out construction consisting of a few parts, what has the usual price and operational advantages.
