Description

The invention relates to a closure and night ventilation device for single, double or multi-leaf shutters of windows, doors and the like with a base plate which can be fixedly attached to one of the shop wings, a bearing plate which can be fixedly attached to the frame or to the other of the shop wings is a swivel bolt which is articulated on the bearing plate and can be pivoted relative to the latter about an axis which is essentially perpendicular to the main plane of the bearing plate, the swivel bolt in the assembled state of the closure and night ventilation device in the closed position of the shop wing and in at least one night ventilation position, in which at least one shop wing is slightly open, can be brought into a locking position by a pivoting movement, in which it is in engagement with the base plate, so that movement of the shop wing is prevented.

Such shutters are freely available commercially and are used to maintain mainly double-leaf shutters of windows, doors and the like either in the closed state, in which the shutters are essentially in a plane in front of windows or doors, or in a night ventilation position which the shops run at an obtuse angle to each other.

These shutter locks essentially have a base plate for fastening to one of the shop wings and a bearing plate for fastening to the other of the shop wings. A pivot bolt is provided on the bearing plate and can be pivoted in a plane running essentially parallel to the main plane of the bearing plate.

In order to fix the two shop wings in their closed position, an essentially U-shaped and upwardly open swivel bolt receptacle is provided on the base plate in the known shop closure, with which the swivel bolt can be brought into engagement by a swivel movement.

In order to be able to fix the two shop wings even in the slightly open gap ventilation position, a coupling pin is provided on the base plate, onto which a coupling sleeve provided at the free end of the swivel lock can be pivoted, whereby a connection is established between the base plate and the bearing plate and thus a movement the shop wing is prevented.

The known shutter locks for double-leaf stores have the disadvantage that their locking positions are not secured and, in particular in the night ventilation position, there is the possibility of unlocking them from outside by swiveling the pivot bolt upwards, which means that the security function provided by the stores is at least largely obsolete.

From DE-C-819 370 a closure and night ventilation device is known, in which the swivel bolt can be secured in the night ventilation position via a safety lock. For this purpose, an angle having an opening is provided on the base plate, the opening being aligned in the night ventilation position with an opening provided at the free end of the swivel bolt. The shackle of the security lock can be passed through both openings, making it impossible to swing the swivel bolt out of the swivel bolt holder.

From FR-A-320 571 a device for locking shutters in a closed position is known. In the exposed leg of the U-shaped swivel bolt receptacle, an opening is provided through which a latching element can be passed from the outside, which engages in a recess provided in the swivel bolt when it is in the swivel bolt receptacle. For swiveling the swivel lock out of the swivel bolt receptacle, the locking element must be pivoted away from the shutter against a spring preload. Locking the shutters in a night ventilation position is not possible with this device.

The invention is therefore based on the object to provide a closure and night ventilation device for one-, two- or multi-leaf shutters, which has defined, secured locking positions, the reaching of which is clearly recognizable for the respective operator and which also prevents an unlocking from the outside shall be.

This object is essentially achieved in that a locking head is held in a recess of the base plate or the bearing plate and can be moved in this recess substantially perpendicular to the locking pivot plane of the pivot bolt, and that the locking head by a in the base plate or the bearing plate arranged spring element is biased and protrudes over the base plate or the bearing plate.

The locking head preferably has an inclined slope which is associated with the swivel bolt and which cooperates with the swivel bolt in such a way that the locking head counteracts the swivel movement of the swivel bolt into the locking position from the swivel plane of the swivel bolt Spring force of the spring element is moved into the recess of the base plate or the bearing plate.

According to an advantageous embodiment, the locking head is released in the locking position of the pivot bolt, so that it projects into the pivoting plane of the pivot bolt by the spring force of the spring element and prevents an independent pivoting movement of the pivot bolt from the locking position.

It is accordingly essential for the invention to have an integrated latching mechanism which, when the pivot bolt is pivoted into the respective locking position, is effective both in the closed position and in the night ventilation position and prevents the pivot lever from being pivoted out of the locking position without a separate unlocking operation.

Since the locking mechanism must be run over by the swivel bolt during each locking operation and the operator inevitably feels and notices the resulting snap-locking connection, correct and complete locking is also continuously promoted in this way.

In order to enable unlocking, the locking mechanism must be released, which can be carried out easily from the inside of the shop, but can hardly or not be reached from the outside even in the night ventilation position.

The locking mechanism is preferably implemented using a locking head, which is arranged in a recess in the base plate or the bearing plate and is movable therein perpendicular to the pivoting plane of the pivot bolt and is pressed into the pivoting plane of the pivot bolt by the spring force of a spring element. The locking head has an inclined run-up surface which cooperates with the pivot bolt in such a way that the locking head in the event of a pivoting movement of the pivot bolt the locking position is pressed against the spring force of the spring element into the recess of the base or bearing plate and thus clears the way for the pivot bolt. In the locking position itself, the pivot bolt releases the recess again, so that the locking head is returned to its starting position by the spring element, in which it prevents the pivoting lever from pivoting back. Swinging the lever back before opening the shutters is only possible if the locking head is manually returned into the recess, which is practically impossible from outside the shutters, i.e. the risk of break-in is considerably reduced and the shutters can be more secure - and also perform a protective function in the night ventilation position.

The latching mechanism is preferably integrated into the base plate, the locking head being arranged centrally with respect to the U-shaped pivot lever holder. The leg of the U-shaped pivot lever receptacle opposite the base plate preferably consists of two spaced guide pins, between which a dome pin is located, this dome pin cooperating with a sleeve formed on the pivot lever in the night ventilation position.

In principle, it is also possible to provide sleeve elements on the base plate and pin elements on the pivot bolt in order to couple the two shutters in the closed position and in the gap opening position in the manner described, but also in this case the latching mechanism acts in the manner already explained.

Furthermore, it is possible to provide the latching mechanism on the bearing plate and to design it in an analogous manner, but preferably the latching mechanism is integrated into the base plate.

An embodiment in which the locking head is part of a is particularly advantageous and convenient is two-armed blocking lever which is pivotally mounted in the base plate or the bearing plate in a plane running substantially perpendicular to the pivoting plane of the pivot bolt and projects with its other actuating end from the base plate or the bearing plate. By this measure, the locking head can also be moved in the cases in which it is not freely accessible for direct actuation, simply by pulling on the actuating end of the blocking lever from the pivoting plane of the pivoting bolt, in order to enable the store or shops to be opened. This can then be made even easier by providing a pull ring at the actuating end of the blocking lever.

the device of Figure 4 in side view.

Figures 1 to 3 show a device according to the invention for double-leaf shutters of windows, doors and the like, this configuration being only an example.

Such a device includes a base plate 1, which is attached to a shop wing 2, and a bearing plate 3, which is attached to the other shop wing 4 (see FIG. 3).

The attachment is carried out by screws, not shown, which extend through through openings 5, 6 provided in the base plate 1 and in the bearing plate 3.

A pivot bolt 7 is pivotally mounted on the bearing plate 3 by means of a bearing pin 8, the axis 9 of which runs perpendicular to the image plane of FIG. 1, so that the pivot plane of the pivot bolt 7 is parallel to the image plane of FIG. 1.

As can be clearly seen in FIG. 6, the base plate 1 has an essentially U-shaped and upwardly open swivel bolt receptacle, into which the swivel bolt 7 is pivoted when the shop wings 2, 4 are closed, in order to fix the shop wings 2, 4 in the closed position . To position the shop wings 2, 4 in the so-called night ventilation position, in which the shop wings 2, 4 are slightly open, as shown in FIG. 4, there is a dome pin 11 on the base plate 1 and a dome pin 11 on the free end of the pivot bolt 7 assigned coupling sleeve 12 is provided. The coupling sleeve 12 is placed in the night ventilation position of the shop wing 2, 4 with a pivoting movement of the pivot bolt 7 on the coupling pin 11, wherein it is guided by guide pins which are arranged on both sides of the coupling pin 11 on the base plate 1 and together with this a leg of the U -shaped swivel bolt receptacle 10 form. In this state, movement of the shop wings 2, 4 is only possible to a minor extent.

In order to lock the swivel bolt 7 in the two locking positions explained above, namely the closed position and the night ventilation position, a latching mechanism is provided.

This includes a locking head 14, which is arranged in a recess 15 in the base plate 1 and can be moved therein perpendicularly to the pivot plane of the pivot bolt 7, that is to say perpendicular to the image plane of FIG. 1. The locking head 14 is pressed into the area of the U-shaped swivel lock receptacle 10 by a spring, for example a leaf spring, which is arranged at the rear in a recess in the base plate 1 and is not shown and has a run-up slope 16 on its upper side. This interacts with the lower edge 17 of the pivot bolt 7 when it is brought into its locking position, so that the locking head 14 is pressed against the spring force into the recess 15 of the base plate 1 and the U-shaped pivot bolt receptacle 10 is released.

As FIG. 1 shows, the upper edge 18 of the swivel bolt 7 in the locking position releases the recess 15 in the base plate 1 again, so that the locking head 14 is returned to its starting position by the spring force. In this, the underside 19 of the locking head 14, which runs perpendicular to the pivot plane of the pivot bolt 7, prevents the pivot bolt 7 from pivoting back.

In order to be able to pivot the swivel bolt out of a locking position again, the locking head 14 must be brought into the recess 15 in the base plate 1.

For this purpose, in the illustrated embodiment, the locking head 14 is designed as one end of a two-armed blocking lever 20 arranged in a rear recess in the base plate 1, of which the other end, namely the actuating end 21, can be seen in the drawing which protrudes from the base plate 1 and on which, for example, a pull ring 22 is provided. As indicated in Figure 2, the blocking lever 20 is mounted in the base plate 1 about an axis, not shown, which is perpendicular to the image plane of Figure 1, so that the locking head 14 simply by pulling the pull ring 22 against the spring force of the leaf spring can be withdrawn into the recess 15.

The device according to the invention can be assembled in the same simple manner as a conventional closure device of this type, but in contrast has the functional advantages which have already been explained and which are very important in practice. It can also be used for right and left-hand use without any problems. It is just as safe and effective in single-leaf, simple and small shops as in multi-leaf shops.
