Description

The invention relates to a bar lock according to the preamble of Claim 1.

Usually there are door or window locks of conventional Falzseitigen striking plates and corresponding locking pin, which lock a wing against a frame frictionally and positively so that the wing can not be opened from the outside. These locks can be replaced by an additional security in the form of a bar lock strengthen in terms of force and form fit.

From DE 38 44 627 C2, such a fitting is known, whereby additionally secured a window wing equipped with locking means is. This fitting is subsequently placed on the wing. The flat-shaped gearbox is located between the wing surface and used to remove before mounting handle handle. through The gearbox can be moved up and down against each other Controlled locking bars, whose free ends in each case mounted in the frame side Counter-closing parts are insertable. The locking bars are over the transmission in operative connection with a nut, which of a drive pin the handle handle is interspersed. Starting from the closed position, at the two locking rods extended maximum in the counter-closing parts are introduced, after a first partial rotation of the Nut, which moves the locking bars in their open position, a second Partial turn done, in which only the lower locking bar back into their Closed position is controlled. The upper latch bar remains in contrast their retired position. In this position is the tilting the sash possible, the wing also in this tilted position is additionally secured.

Furthermore, it is known from EP 0 779 945 B1, within such Additional fuses to arrange signaling contacts in order to be able to integrate to create alarm systems. In overcoming the conventional Interlock, the signaling contacts trigger a silent alarm to the time delay until the complete overcoming of the Use additional security to initiate appropriate measures.

The problem with the prior art is the interaction between the locking bars and the counter-closing parts, in particular in the Tilting position of the wing. In a burglary attempt with massive Force, the locking bars can bend and out of the Slip counter lock parts. In addition, such rod locks can be only conditionally and unfavorably to existing door or Integrate window systems. In particular, the formation of abutting edges and the possibility of unprotected and violent access on functionally relevant components is operator side and cleaning technology disadvantageous.

It is therefore the object of the invention to a bar lock after further develop the preamble of claim 1 so that the burglary protection functionally increased and the usability is improved.

This problem is solved by the features of claim 1 Features. Advantageous embodiments of the subject of the claim 1 are given in the subclaims.

The bar lock according to the invention according to the claim 1 has the advantage that a Verhakungsmechanismus between a Lock bar and a counter-closing part is formed. At a massive Force in the case of burglary hooks the free end of the locking bar in the counter-closing part, so that continues to be a safe seat of Lock bar is guaranteed in the counter-closing part. Both the locking bar as well as the counter-closing part consist of heavy-duty Materials. For this purpose, in particular metallic materials are suitable. To the system also at the supposed weak points, namely the connection points to the frame or the wings, sufficient massively interpreted, are the counter-closing part and a sleeve for leadership the locking bar possibly with several screws possibly under use attached by additional reinforcing means. The inventive Bar locking thus resists the usual burglary attempts and represents a simple and retrofittable solution System can be used both with rotary blades and with so-called rotary tilting wings as well as sliding and slide-in sashes. Under wings Here are all at least in one direction swiveled or movable Wings of doors, windows or the like understood.

The bar lock according to the invention can preferably be retrofitted on the fitting integrated in the sash for opening and closing be mounted so that the normal use of the wing continues Unlimited without loss of comfort is possible. This is the fitting replaced and the locking bars with their Gegenschließtei- - len mounted on the wing or on the frame, so that the material and installation costs is extremely low, especially with regard to The fact that the usual fitting parts only partially replaced Need to become.

The conventional latch between the frame and the wing at the fold side remains unchanged. A second and additional Lock then forms the rod lock according to the invention. The bar locking can be done by dimensioning the locking bars be varied in terms of material, length and diameter and offers a potential burglar a much greater resistance as the conventional lock.

The at least one displaceable locking bar is provided with an opening of the Gegenschließteiles engageable, with the locking bar on the wing and the counter-closing part are arranged on the corresponding frame. Such a locking bar can be made very solid, so that whose overcoming requires a large temporal bond of the burglar or even discouraged. These are in a preferred embodiment at least two locking bars in opposite directions verschiebar arranged on the inside of the wing, with the corresponding Counter-locking parts for fastening in opposite places the frame are provided. In a first closed position introduced the two locking bars in their respective counter-locking parts. In the so-called Kippstellung is only a locking bar in her Counter-locking part introduced while the opposite locking bar and parts of the seam-side closing means are disengaged. Instead provides over the tilt axis a locking bracket for a sufficient Stop the wing. Even in this tilted position is the wing with the one-sided acting bar locking sufficiently against Burglary secured.

In a first advantageous structural embodiment of the invention has the locking bar in a sleeve attached to the wing frame is guided, at their free end, with which they in the counter-closing part is insertable, a circumferential groove on. The counter-closing part is with a Base plate attached to the frame and has an opening which has a slightly larger diameter than the locking bar has. Within This opening is a cut shoulder, in the burglary case after overcoming the first conventional locking with the groove engages because the wing then makes a horizontal movement experiences. A vertical component of movement which ultimately leads to deflection would cause the locking bar is thereby effectively prevented. In the necessary for the formation of the shoulder free punch can be a flexible Element arranged, on the one hand the vertical guidance of the Raised bar increases, but on the other hand is sufficiently deformable to Burglary case the interaction between the groove and the shoulder too guarantee:

The opening or the locking bar can be provided with an insertion edge be to introduce the locking bar even with operation-related or with temperature-related tolerances. Furthermore it is possible, the opening of the counter-closing part axially sloping expand, so that the rod lock according to the invention can also be used for rotary tilting sashes. The upper latch bar is then no longer engaged with the counter-closing part. A locking bar limits the tilt angle of the wing. In a burglary attempt in the Tilting position of the wing, the locking bar is moved either horizontally or brought into further skew, so that in any case the groove interacts with the shoulder. In addition, another Shoulder in the opening to prevent slipping.

Each counter-closing part has a basically rectangular plan. To determine the counter-closing part serve screws that in the Intervene frame. This is z. B. with the interposition of a spacer possible, if insufficient material thickness of the frame is used and has in the area of screws hollow rivets. The Spacer could also be designed in several parts, so that a disc-like corresponding variable superposing is possible.

Advantageously, a base plate is formed on the frame is screwed. Preferably, the counter-closing part can subsequently pushed laterally and screwed. The base plate and the Gegenschließteil have complementary trained facilities, the one positive and in the horizontal direction non-positive connection enable. The counter-closing part is through these measures been optimized, so that a solid resistant block component arises.

In a further embodiment of the invention is a counter-closing part, which secures a wing in such a way that, in case of stress, the If the wing is broken, a pulse to activate a Downstream alarm system is generated. For example, by Interruption of printed conductors emitted an electrical pulse, wherein with simultaneous severing of Abreißschrauben the downstream Bar lock the reinforced main load attack can take over. The tear-off screws avoid an accidental Loosening or removing the push element or response of the signaling contact. By overcoming the conventional latch Activated detectors will trigger a safe alarm and a break-in attempt is clearly documented so that it can be reliably recognized whether this or a false alarm was the cause of the alarm. Advantageously, such only at the lower counter-closing part Detector arranged, as this is sufficient even with tilt-and-turn wings. Another advantage is that the detector from the outside or can be put into the alarm-ready state from the inside. The Locking can also be additionally provided with a signaling contact, which sets a switching pulse when the window is closed.

In this case, the counter-closing part has a pushing element which is moved by the burglary stress from a rest position and thereby activates a detector. Conceivable here are optical, magnetic and / or electrical detectors, z. B. boards, reed contacts, etc. In this case, in the thrust element is the opening for receiving the locking bar formed, wherein the thrust element in a corresponding Recess of the counter-closing part is movably guided. By doing Thrust element is further formed a chamber, which is for receiving a lug-shaped approach is used, which integrally into the recess of the counter-closing part slidably extends. By the interaction of the chamber and the lug is the pusher element guided in the recess of the counter-closing part. The approach has an eyelet in the rest position with the opening in the pusher element is aligned to accommodate the locking bar can. In case of burglary the entanglement between the locking bar and the counter-closing part the shape that the pusher together with the locking bar from his original position is shifted and the groove at the free end the locking bar engages behind a shoulder on the stationary eyelet.

Since the bar lock usually to existing conventional Latches is retrofitted, is a visually appealing Integration to the wing design desirable. Between the handle handle and the top or bottom edge of the wing are uniform for this purpose and continuous covers available. Both the locking bar as well as their pods are completely covered. These covers are pushed on the sleeves and the handle handle or clipped on. The counter-closing parts have the same color and Outer shape as the covers on, so that a uniform picture is created. The counter-closing part is facing the locking bar Side with a cutout, so that the cover of the locking bar pivoted in the tilt position of the wing in this cutout can be. It is thereby avoided that the cover and affect the counter-closing part in the tilt position of the wing.

A in the figures only partially illustrated window 1 consists in in a known manner from a frame 2 and from one to the Frame 2 mounted wings 3, the one of a sash 4. z. In The shape of a profile is surrounded. The window 1 is a turn-tilt window whose wings 3 are rotatable about an axis and about another Axis is arranged tiltable. For this purpose, the wing 3 with the frame. 2 connected by means not shown hinges, wherein the hinge is uncoupled to achieve the tilted position. The wing 3 has fold-side Locking elements, which can be displaced by means of a handle handle are. The grip handle can also be locked. Between the handle handle and the sash 4 is designed in a flat shape Transmission of a bar lock 5, from the top and projecting down latch bars 6, which mounted in frame side Counter-closing parts 7 are insertable. The locking bars 6 and the counter-closing parts 7 are made of solid metallic materials.

The detailed explanation and representation of the rod lock 5 limited subsequent to the area of the lower locking bar 6 and the processes taking place there. The locking bar 6 is by means of a sleeve-shaped bearing element 8 guided on the sash 4. Escaping to the locking bar 6 is on the frame 2, the counter-closing part. 7 arranged, wherein a free end 9 of the locking bar 6 in a shaft-like cylindrical opening 10 of the counter-closing part 7 can be inserted. The opening 10 has a slightly larger diameter than the locking bar 6 and is oriented in the axial longitudinal extent. Of Furthermore, the opening 10 has additional free spaces 11, which pivot enable the locking bar 6. Extend the free spaces 11 the opening 10 corresponding to the normal tilt angle of the locking bar 6. The free end 9 of the locking bar 6 has a circumferential groove 30 and end a circumferential insertion edge 12, the insertion into the Opening 10 facilitates.

The counter-closing part 7 is as cuboid and solid resistant Block component formed. To determine the counter-closing part 7 is a base plate 13 is formed, which screwed to the frame 2 is. Preferably, several screws 14 are used for this purpose, wherein at least one bolt 15 embedded in the frame 2 is screwed. The counter-closing part 7 has a receptacle 32 to to be pushed laterally on the base plate 13. This creates a positive connection between the base plate 13 and the counter-closing part 7. The counter-closing part 7 is by means of grub screws 16 screwed to the base plate 13.

Between the handle handle and an edge 17 of the sash 4 is a U-shaped cover 18 is present, both the locking bar. 6 as well as their bearing element 8 completely covers. The cover 18 is deferred or clipped on. The counter-closing part 7 has the same Color and the same outer shape as the cover 18, so that a uniform picture emerges. The counter-closing part 7 has an oblique Free cut 19 on to properly tilt the wing 3 including allow the cover 18.

The counter-closing part 7 according to the figures 1 to 5 additionally has Pusher 20, which in a corresponding recess 21 of the Counter-closing part 7 is guided displaceably. In the pushing element 20 is the opening 10 for receiving the locking bar 6 and the other a chamber 22 is formed, which is adapted to receive a tab-shaped Approach 23 is used, which is integrally formed in the recess 21 of the Counter-closing part 7 extends. Through the interaction of the chamber 22 and the projection 23 is the thrust element 20 in the recess 21st of the counter-closing part 7 slidably guided. The approach 23 has a Eyelet 24 in the normal position with the opening 10 in the pusher 20 is aligned to accommodate the locking bar 6 can. Between the counter-closing part 7 and the pushing element 20 are tear-off screws 25 arranged, which is an accidental loosening or removal of the thrust element 20 avoid. The Abreißschrauben 25 are of springs 26th surrounded in the normal position of the bar lock 5 under Preload stand. Furthermore, the counter-closing part 7 and the Push element 20 through a continuous slot 27, in a burglar alarm 28 is arranged.

The operation of the bar lock according to the invention will be described below 5 described in more detail. In the normal operation of the wing 3 by means of the handle handle when opening not only the fold side Locking elements unlocked, but at the same time the locking bars 6 pulled out of the counter-closing parts 7 and vice versa. To achieve the tilting position of the wing 3, the upper hinge uncoupled and the upper locking bar 6 from the corresponding counter-closing part 7 pulled while the lower locking bar 6 in the lower Counter-closing part 7 remains. The wing 3 has to top one Locking bracket on, which defines the maximum tilt angle.

In the embodiment according to Figures 1 to 5, the counter-closing part 7, a pusher 20 and a burglar alarm 28, the is formed in the form of a circuit board provided with printed circuit boards. advantageously, is only on the lower illustrated closing part 7 such Burglar alarm 28 arranged, as this is also true with tilt and turn wings is sufficient. In the closed normal position of the wing 3 results a position according to the figures 3 and 4a, while the figure 4b of Situation with a wing 3 in tilted position corresponds. In both If necessary, the burglary alarm 28 can be set by an alarm system be armed. The rod lock 5 can be Also provided with a signaling contact, which has a switching pulse settles when the wing 3 is closed.

Be in the event of burglary not shown Falzseitigen Closing elements, for example by Aufhebein the wing. 3 Forcibly overcome, so the wing 3 in the breaking direction so open wide until the locking bar 6 according to Figure 4c on a shoulder 29th the eyelet 24 of the counter-closing part 7 is applied. This tear the Tear off screws 25 and the burglar alarm 28 with the applied conductor breaks and can thereby a switching pulse or a message to a downstream control of the alarm system drop. The released during this movement springs 26, the are installed with bias, push the pusher 20 in the breaking direction and prevent its return movement. The locking bar 6 shifts thereby within the eyelet 24. There is a Verhakung between the locking bar 6 and the counter-closing part 7, wherein the groove 30 at the free end 9 of the locking bar 6, the fixed eyelet 24 at a Shoulder 29 engages behind. Removing the locking bar 6 from the counter-closing part 7 is effectively prevented, so that the deflection of the wing 3 or the complete rod lock 5 not possible is. Now the wing 3 is indeed opened by a small gap, but set the voltage applied to the counter-closing parts 7 locking bars 6 the Burglars face increased resistance to a burglary prevented or at least complicated.

Further embodiments of the counter-closing part 7 are shown in FIGS. 6 and 7, wherein the embodiments in the embodiment of the burglar alarm 28 different. According to Figure 6 is the platinum-shaped Burglar detector 28 replaced by a reed contact. In FIG. 7, the board-shaped burglar alarm 28 is not in a slot 27 between arranged the counter-closing part 7 and the pusher 20, but by means of screw elements 31 between the contact surfaces of the counter-closing part 7 and the pusher 20 attached.

Furthermore, the rod lock 5 additionally with a signaling contact (not shown) which provides a switching pulse settles when the wing 3 is closed. This one can be in style that in the locking bar 6 a small, preferably round, permanent magnet, is introduced and in the counter-closing part 7 a hereby agreed Reed switch is arranged, the overlap the switching pulse generates and switches.

FIG. 8a-c shows a basic version of the bar lock 5, the only mechanical reinforcement conventional Locks allows and especially for easy retrofitting existing mechanisms is suitable. Since there is no connection is present at an alarm system, also simplifies the assembly and the functional principle. The main difference between the above-described embodiments is that no separate here Push element 20 is needed. After overcoming the conventional Lock hooks the locking bar 6 with its groove 30 behind the shoulder 29 in the counter-closing part 7 and prevents or impedes one Burglary.
