Description

SALPALAITE - REGELANORDNING 109929

The invention relates to a latch device according to claim 1 for a door, window, hatch or similar component.

Hinged double doors and sliding doors, windows, hatches or the like are commonly used for locking purposes. a quick-release latch with a trigger mechanism at a height of about 1.5 m or sometimes lower. One very typical application of such a latching device is the lesser opening of the double door. In a so-called recessed quick latch, the transfer bars, or locking bars, are located inside the door and extend to the counterparts in the upper frame and the sill or the floor, whereby the door is closed and at the same time. in the locked position. Often used is a metal profile door structure, which, especially in the exterior doors of the building, has a so-called.

the thermal break structure. In this case, the door profile is usually divided into two sections by a partition, the distance of which from the surface of the door edge varies with different profiles. Therefore, it is often impossible to install a quick release latch with transfer bars on such a door without a special mounting plate or other special arrangement.

. . It is an object of the invention to provide a quick release latch suitable for most doors, windows, hatches, or the like, since the position of the transfer bar at the edge of the door. measured from the surface may vary. Another purpose is to present a quick release latch that fits • · doors made of a rather thin door profile, up to a profile well below 40 mm. However, it is also intended that, with its strength and: T: other features, the quick release latch meets the requirements for a Class 1 security lock in both wooden and metal doors. It is also necessary that the quick release latch according to the invention f t ·. * · Can be equipped with conventional accessories for quick latches, such as emergency escape hood, padlock accessory, transfer bar accessory, subframe for button operation, etc.

• · · • ·

The object of the invention is achieved as set forth in claim 1 and other claims. The latching device is intended to be mounted on a door, window, hatch or similar component and includes a 2 109929 recessed latch body with operating handle, to which at least one but preferably two locking rods resting on the door opening or door frame or threshold can be attached. If at least one locking rod is present at a depth which may vary with respect to the edge surface of the door, window, hatch or similar component, the locking rod may be at a depth from the surface of the edge of the door such that the heat break may be in place, so the insulating property of the door profile remains unchanged outside the quick latch frame. Thus, no elevation plates or similar inserts are required.

If the depth of the locking bar from the peripheral surface of the component can vary infinitely, no special adjustment is required during installation.

For most heat break profiles, it is sufficient that the depth of the locking rod from the surface of the peripheral region of the component may vary within a depth range of 11 ... 18 mm from the center of the locking rod, but preferably over a wider range. A depth range of 11 mm downwards is almost never necessary. For reasons of strength, the locking rod must be strong enough to prevent buckling or. · Cutting.

For construction, it is recommended that the locking rod be shaped at the end of the latch body to allow the locking rod to move in the depth range specified in the: T: slot or similar depth direction.

• · · v · 'Such a structure is quite simple to manufacture and robust and very reliable.

It is recommended that the locking rod be located at different depths in the aforementioned »· v .: depth direction, but not at the end guide. The placement of the end guide and: ... · the counterpart determines the position of the door or similar component in the frame:: and this has a significant effect on the tightness and functionality of the door / frame assembly in general. The position of the locking rod other than the end guide 3 109929 has virtually no meaning, as long as the locking bar can only be within a depth within the permissible depth range.

If the locking bar is secured to the latch body by turning the locking bar 1 kier turn, a very simple and fast mounting structure is obtained and there is no need, for example, for easily damaged and difficult to manufacture threaded connections.

If the rotation of the locking rod is prevented by designing the end guide and the locking rod to be attached to the structural member in such a manner that the locking rod cannot rotate in the end guide, the design is very reliable and simple.

It is recommended that the latch actuator is optionally operated with either a quick-release lever or a door knob or the like. This allows the same locking frame to handle a wide variety of locking needs in different areas of the building.

If the latch body is positioned when using the button on the sub frame that includes. . at least the breast plate and the cover plates, the structure can easily be made solid and tidy, since the structure then resembles a conventional sinkhole. Buttons. eg buttons similar to the other doors in the building can be selected • ••• ί is.

«*: T: If the latching device has a locking bar movement of at least 20 mm, the latching device in this respect fulfills the condition for Class 1 locking.
