FI105846B - External opening device for the lock of an inward-opening balcony sash window without vertical window sash - Google Patents

Abstract

The invention relates to an opening device with which the locking mechanism on the lower window sash of an opening balcony window which has no vertical sash and which has bearing members at the top and guidance at the bottom can be opened from the outside of the balcony. The need to open a balcony sash window from outside arises in emergency situations, for example, so that, using a rescue ladder, a person can attempt to get from a balcony above to a balcony below which is protected by a glass window. The external opening device for the lock of the balcony sash window is designed with a lifting handle 14, which is mounted in the lower window sash 4 and is fixed in a locking mechanism 10 which is rotated on a shaft 11 provided with a rotary piece 12, placed on its inside, so that the lifting handle 14 is fixed in the locking mechanism 10 in the gap between the lower window sash 4 and the outer edge 18 of the lower rail 2. Upon displacement of the lower window sash 4 and, at the same time, the sash window 5, the lifting handle 14 moves between the lower window sash 4 and the lip-shaped sealing strip 16, which is fixed in the lower rail 2 and presses against the lower window sash 4, the lifting handle 14 passing through a hole drilled in a drip moulding 15 formed on the lower window sash 4. <IMAGE>

Unlocking device for locking inwardly opening vertical frameless balcony slide> ♦

The invention relates to an unlocking device for opening a locking latch in the underside of a balcony frame which is supported by a vertical frame and which is guided from below and which is guided from below.

Nowadays, it is common to install window glazing on balconies, which can increase balcony usage time in autumn and spring.

Typically, these balcony windows are constructed between a balcony railing and an overhead balcony or balcony roof with vertical, frameless sliding glazing that is guided by the top rail and guided by the bottom rail. As the balcony window consists of several sliding glasses, they can be easily opened and moved by hand. To open part or all of the balcony opening, they are designed to be opened inward, one at a time at one end of the balcony opening, parallel to the side wall of the balcony, and at the same time bundled. Opening inwards results in a safe cleaning of the outside of the glasses. In normal use, the windows are either fully closed or open across the entire width of the window opening.

Fully enclosed balcony goggles also prevent outside noise from penetrating inside, as well as reducing heat loss in the room behind the balcony.

The well-known vertical frameless, top-supported and bottom-guided inward-facing balcony slide goggles are invariably intended for inward opening. This is simply because there was no need to open the balcony glasses for their intended purpose from the outside. This is also thought to increase safety. For this reason, the mechanisms designed to unlock them only work from inside the balcony. The mechanisms for opening the balcony windows are attached to either of the lower or upper frames and 105846 2 follows each of the sliding balcony window elements and acts as a lock for the frame and at the same time for the glass. Balcony window elements can only be opened at a pre-selected end of the balcony opening and at a specific location. This has also led to the design of the upper and lower guide rails to be uniform to the entire width of the balcony and thus look and fit very well into the actual building. This design allows the upper and lower rails, together with the glasses, to stop wind and water. In particular, the lower rail is made watertight over the entire length of the lower rail, for example by means of a lip-sealed sealing tape. It is also common to equip the lower rail with a wide water damper on the balcony.

With the entire window opening closed, opening the balcony slide glasses from the outside is thus not possible without violence, such as breaking a glass. This is especially true if the upper rail and / or lower rail is installed inside the balcony railing, depending on the balcony destination.

The need to open from the outside arises in the event of a rescue, for example when using a safety ladder from an upper balcony to a lower glass-enclosed balcony.

An exterior opening may also be required by a ladder rescuer or a firefighter. In the event of a rescue, opening from the outside must be quick and can be done with one hand. The latch release release device shall also be easily discernible.

The opening problem described above can be eliminated by a vertical opening frame unlocking device for opening a balcony window according to the invention, which is characterized in what is defined in the symbol section of the claim.

The main advantage of the present invention may be considered to be its operation in the above-described escape situations. It is easily visible from the outside of the balcony due to its bright red color 105846 3. It is quick and easy to use. Opening the balcony window is power-free and can be done with one hand. Also important is the fact that the windows can be opened and closed from the inside of the balcony normally with the external opening device always ready for operation. Due to its small size, the outside opening device is unobtrusive from the inside of the balcony.

The invention will now be described with reference to the accompanying drawings.

In Fig. 3, the outermost sliding glass 5 is opened to pivot it through the lower and upper hinges 9 and 7 into the balcony.

Fig. 4 is a sectional view B-B of the bottom rail 2 viewed in the direction of the outermost slide 5. The locking catch 10 is secured to the lower frame 4 by an axis 11 having a torsion knob 12 at the inner end of the balcony.

The pin 13 prevents the locking catch 10 from rotating on the shaft 11. A flexible lifting lever 14 is attached to the outer edges of the locking catch 10 at the center.

The lifting lever 14 rises between the lower strap 4 and the lip sealing strip 16 which presses against it, and at the same time the outer edge 18 of the lower rail 2, and pierces the drip lug 15 formed in the lower strap 4 from the drilled hole therein. A lip-like sealing strip 16 of the entire length of the lower rail 2 is secured to the upper part of the outer edge 18 of the lower rail 2.

Figure 5 illustrates a situation in which the outermost glass has just been opened.

The locking lever 10 is pivoted to the upper position and just passes over the inner edge 17 of the lower rail.

To open a completely closed balcony window from the outside, proceed as follows.

When manually lifting the lifting lever 14, the locking lever 10 secured to the lower frame 4 by a shaft 11 and secured by a pin 13 is rotated horizontally to the upper position. When the movement of the lifting lever 14 stops when the locking lever 10 reaches the upper position, the sliding glass 5 is pushed inward without removing the lifting arm 14 from the lifting arm. The slide 5 can be pushed fully open.

It will be apparent to one skilled in the art that the invention is not limited to the example described above, but may vary as follows:. . Because the lifting lever 14 is made of a flexible material such as plastic, it can be made of a different color to improve rapid perception.

The slides 5 may be provided with a separate pull knob mounted on the lower frame 4 on the droplet 15 to facilitate external displacement of the slides 5 and to increase the resulting opening.
