Abstract

A drive pivots the pivot bolt (11,12) out of its open position into a bolt position and has a push bar (14) activated by a handle and acting directly on the pivot bolt. On the panel or pane is fixed a lock box for engagement of the pivot bolt in the locked position. The handle of the push bar (14) is a push handle (13), which is fitted on the housing (10) in the adjustment position of the push bar and is coupled rigidly to it. The push handle extends visibly and exclusively in the open position of the pivot bolt over the outer periphery of the housing.

Description

The invention relates to a fuse for door or Window sash, with a housing attached to the frame, in which at least one swivel bolt is mounted with a swivel bolt drive, the swivel bolt from a Can pivot open position into a bolt position and also a directly acting on the swivel bolt, from a handle has an actuated push rod, and with one Lock box fastened to the sash for engaging the swivel bolt in the locking position.

A backup with the aforementioned features is out known from EP 0 663 500 A1. The well-known housing is in the Frame installed and stored by gravity in the essentially vertically hanging swivel latch. This is because of it to pivot from its open position into the latch position, that the wing-side, designed as a drive rod Push rod adjusts an actuating pin that on one Driver of the swing bolt acts and this accordingly the adjustment of the push rod is pivoted until the Swivel bolt in the lock case located on the sash intervenes. The known fuse requires that the Frame and the sash each have a recess Includes the pivot bolt and the wing side Driving rod with its actuating part on the positioning the swivel lock is matched.

In contrast, the invention is based on the object a backup with the characteristics mentioned above improve that problem-free retrofitting of the backup independently possible from a wing-side connecting rod fitting is the problem-free detection of the functional state of the backup.

This object is achieved in that the handle of the Push rod is a push handle that is on the housing in the Adjustment directions of the push rod and with this is rigidly coupled.

It is important for the invention that the handle the push rod is a push handle. This sliding handle is either in its one position, the Open position of the swivel bolt corresponds or in their other Position that corresponds to the locking position of the swivel lock corresponds. This sliding handle is on the housing in the adjustment directions the push rod and rigid with this coupled. As a result, the user has direct influence exclusively on the functional position of the push rod. He has the function of securing directly in hand. He can feel when the fuse is working, or out of order. He can also perform this function test when it's dark or when he doesn't have a key to Hand has, provided the lock can be operated. The Sliding handle also enables the fuse to be actuated with great speed and without special attention. The rigid connection of the push handle with the push rod as well as the structural uniformity and operational uniformity that this gives lead to compact fuses which as a result result in a particularly high securing effect.

The fuse can be improved in that the sliding handle only in the open position of the Swivel lock visible over the outer circumference of the housing protrudes. The board of the sliding handle over the outer circumference in the main level of the housing or parallel to the frame level shows easily that the fuse is out of function is. If the sliding handle is adjusted so that it no longer protrudes beyond the outer circumference of the housing, can be easily assumed that the Securing exerts its hedging effect.

It is possible to design the fuse so that the Sliding handle has a handling projection on the visible side. The handling projection perpendicular to the frame level is facilitated the operation of the fuse because the sliding handle easier is to be seized. The handling projection can also lead to a advantageous optical design of the fuse used will.

It is possible to design the fuse so that the Slide handle at the bottom of one on the frame attached elongated housing is attached. This is it is possible to control the gravity of the push rod and the push handle exploit to keep the fuse out of function. Such a lower arrangement of the sliding handle is also the most sensible, also with regard to a light one To open.

It can be advantageous to design the fuse in such a way that in the sliding handle a lockable pressure cylinder is arranged, the actuation of the sliding handle by its engagement in the housing or one with it connected part is able to block. As a result, the The fuse cannot be opened without a key. It resists consequently easier unauthorized attempts to open it, for example by burglars or children. Easy to use is achieved when the fuse is closed that the impression cylinder just needs to be pushed in needs when the sliding handle is raised to its closed position has been. The pressure cylinder cannot be in its closed position pressed, this can be a sign that that the fuse is not in the functional position. The impression cylinder can be used particularly advantageously, if the sliding handle has a handling projection on the visible side has because the handling projection to surround the impression cylinder can This will improve protection of the Printing cylinder reached.

In order to significantly increase the security effect, the Fuse should be designed so that two in the same direction swiveling swivel bolts available and from a single Push rod are pivotable. Because the hook bolts in the same direction are pivotable, one is sufficient for their pivoting Push rod. This means minimizing the structural Effort associated with a corresponding improvement in Security against violent break-in.

A structurally simple solution for securing results differs in that the push rod on the housing in their adjustment directions is guided and on the swivel bolts each attacks across cross slots, in each of which a pin of the associated swivel latch engages. The cross slots are only as long as necessary and therefore weaken the cross-section the push rod as little as possible. The cross slots avoid an additional extension of the push rod in their longitudinal direction. The setting pins of the swivel bolts are in place at exactly the same level. As a result, that is to the push rod vertical extension of the fuse as small as possible.

The fuse can be designed so that the Swivel bolt is mounted on a housing pin that the Push rod between the swivel latch and one of the housing final bottom plate is held, and that the bottom plate forms a preassembled unit with the housing. The bracket of the swivel bolt or several swivel bolts the push rod between the housing and the associated base plate results in a minimization of the necessary components for the preassembled unit of the fuse. This this makes it compact and resistant. The pre-assembly ensures the constructively predetermined function of the Swivel lock and the push rod used for it with the associated slide handle. It is impossible that at the installation of the fuse on the window or door malfunctions occur in that on agility of the adjustable components of the fuse becomes.

To adapt the fuse to a variety of needs To be able to, it is designed so that the housing assembly about spacer plates used if necessary a mounting plate attached to the frame is attached. The mounting plate can be attached to the frame and through appropriate measures are adjusted. Then the cultivation takes place the housing assembly taking into account any Spacer plates to adjust the position of the unit vertically to the frame level.

In order to take advantage of the security that the Position the door or window sash as little as possible can be shifted by force, it is possible to secure to be designed so that the swivel bolt on the lock box side has a locking toothing, the one in the locking position Locking teeth of the lock box is adjacent. The locking teeth of the swivel bolt and the lock box into each other as soon as you try the position of the door leaf or to change the sash by force.

Fig. 1 shows the two in a reduced representation Main components of the security for door or window sashes, namely that to be attached to a frame, not shown Housing 10 and one arranged in functional neighborhood Lock box 15. The lock box 15 can on one Wing of a door or attached to the wing of a window will. So that this wing cannot be opened it is possible to interconnect the housing 10 and the lock case 15 to couple. This coupling is done by swivel bolts 11, 12, which have an open position and a locking position. Fig.1 shows it in its locking position, as far as this in Clearance space 26 between the housing 10 and the lock case 15 is recognizable. Another essential part of the backup is a sliding handle 13, which is a pressure cylinder 17 in a handling projection 16.

The illustration in FIG. 2 shows a longitudinal section through the housing 10 other components with which this housing 10 can be attached to the frame. Right on the A frame 23 is a frame with its underside 23 'on. The mounting plate 23 has various mounting holes 27, through the fastening screws 28 in the frame can be screwed in. The fastening screws 28 are, for example, wood screws when the frame is off Wood. Instead of the fastening screws shown 28 other fasteners can be used for example, fastening dowels 29 when the frame is dowel capable.

Usually form the frame and the sash No common level on the inside of the window. That is, the Lock box 15 sits higher than one on the frame attached housing 10. To compensate for this difference in height serves the build plate 23 and fine-tuning can be achieved with spacer plates 22, 22 ', 22' '. Here only the spacer plate is used that corresponds to the respective Height compensation is also needed. All spacer plates have the same outer contour as the mounting plate 23 and how the housing 10. In the area of the mounting holes 27 of the mounting plate 23 are the spacer plates 22 to 22 '' with through holes 30 provided to the fastening screws 28th if necessary, also tighten through these holes 30 or to be able to relax. This is common therefore advantageous because the mounting plate 23 with one or several spacer plates 22 to 22 '' is fitted, the Cohesion, for example, through the locking projections shown 31 of the build-up plate 23 is achieved by this Locking projections 31 in corresponding locking recesses 32 engage a spacer plate 22. Are several spacer plates available, they each have corresponding recesses 32 and locking projections 31.

The mounting plate 23 also has fasteners for the housing 10. Fig. 2 shows fastening nuts 33, which interact with mounting screws 34. The fastening screws 34 pull the housing 10 against the mounting plate 23 or their spacer plates 22 to 22 '' if they are in the Fastening nuts 33 are screwed in, for example are inserted into the recesses 23 '' and there fixed, e.g. by pressing or sticking. The housing 10 is essentially a spacer plate side and at least also with regard to countersunk holes 45 of fastening screws 34 open frame on the visible side a cover strip 35 is closed, so that neither Mounting screws 34 are visible or accessible, still the housed within the housing 10 components of the Fuse. The cover strip 35 is e.g. by latching like this fixed that the interior of the housing 10 is not accessible is.

The housing 10 open on the frame side sits on a Base plate 21, which is directly on the adjacent spacer plate 22 ''. The base plate 21 has recesses 36 provided with locking projections 37 of the spacer plate 22 ' cooperate so that an adjustment of the position of the base plate 21 with respect to the spacer plate 22 '' and the mounting plate 23 is reached. The housing 10 is supported in this way on the bottom plate 21 from that between this and an inner wall 38 a visible housing wall 39 a well-defined Distance or space 40 arises in the Swivel lock 11, 12 and a cooperating push rod 14 are housed. The swivel bolts are 11, 12 massive and occupy the greatest width of space 40. You camp on housing pin 20, on which they are attached. Fig. 2 shows the swivel bolts 11, 12 in their engaged position. They are arranged essentially horizontally. The horizontal Arrangement of the pivot bolt 11, 12 is by means of a Push rod 14 reached, arranged in the transverse slots 18 are, in each case an adjusting pin 19 of the associated Swivel lock 11 or 12 engages. The transverse slots 18 are so long that the visible in the illustration of Figure 3 horizontal movement component of the pivot bolt 11, 12 at Pivoting is mastered. The setting pin 19 is of the associated Housing pin 20 arranged at about 45 °, so that the adjustment range of the adjusting pin 19 somewhat above and somewhat extends below the housing pin 20. Here results a minimal radial adjustment component with the Impact that the transverse slot 18 is kept as short as possible can be.

By moving the push rod vertically in Fig. 3 14 sets the pin 19 from the position shown above the housing pin 20 in a not shown Position below the housing pin 20 moves about equally from a horizontal plane through the housing pin 20 is removed. The required movement of the Push rod 14 between the pivot bolts 11, 12 and the base plate 21 is only vertical. Here is the push rod 14 also performed in the frame level, namely in the housing 10 between the outer peripheral wall 41 and guide projections 42. The leadership takes place such that a tilting of the Push rod 14 in the display plane in every position is excluded. As a result, the lower end 14 ' the push rod 14 only a vertical movement, so that it can be rigidly coupled with a sliding handle 13 can.

The sliding handle 13 includes the lower end 14 ' a dovetail-shaped recess according to FIG correspondingly dovetail-shaped design of the lower End 14 '. The sliding handle 13 is on the housing 10 in the Guided in a longitudinally movable manner, namely with guide rails 43, the lower housing end 10 'outside U-shaped reach around. The design of the outer circumference of the sliding handle 13 is matched to the outer circumference of the housing 10, so that there is a handsome sight. The Sliding handle 13 has a handling projection 16, which is rises above the visible side of the housing 10. The handling advantage 16 makes it easier to move the sliding handle 13 in the vertical direction. The handling projection 16 is designed that of the visible cover strip 35 one Level 44 down to the flat plateau of the handling projection 16 increases. The result is a design that is easy to handle with little risk of bumping or injury.

A pressure cylinder 17 is arranged in the handling projection 16. The pressure cylinder 17 lies approximately with its outer end plan with the plateau of the handling projection 16 if the Printing cylinder 17 is pressed. The indented position is the locked position. This will lock achieves that a locking end 17 'of the printing cylinder 17th engages in a recess 21 'of the base plate 21. It is then impossible to move the slide handle 13 because the positive connection between the pin 17 'and the base plate 21st this prevents.

The pressure cylinder 17 is key-operated in the usual way, can thus by inserting and turning a Key in a position in which the Pin 17 'does not engage in the recess 21'. The sliding handle 13 can then be moved vertically, namely from the position shown in Fig.2 down. Here comes the sliding handle 13 beyond the outline of the housing 10 in an open position. In this open position it is immediately apparent that the fuse is released. The optically light Detectability of the open position of the fuse prevents the incorrect assumption that the fuse is closed. It can therefore easily be remedied if necessary by the sliding handle 13 up into its locking position is moved. At the same time can then from the handling projection 16 protruding pressure cylinder 17 pressed in and thus Avoid unintentional deactivation of the fuse will.

To open the fuse, the slide handle 13 moved down from the position shown in Fig.2, so that the push rod 14 is pulled down accordingly. Here, it presses with the upper edges of its transverse slots 18 on the adjusting pins 19 and thereby pulls the swivel bar 11, 12 from their engagement positions in the lock case 15 describe the hook-shaped swivel bolts 11.12 a practically quarter-circular movement, which despite of the hook ends pointing vertically downwards in FIG is hindered because there is sufficient room for maneuver the hook ends are provided in the lock case 15. Of the Lock box 15 is however provided with support walls 46, which are adjacent to the swivel bolts 11, 12 when they are are in the locking position. In addition, is on these walls each have a locking toothing 25 provided with a Interlocking teeth 24 of a pivot bolt 11,12 cooperate can. This locking teeth 24 of the pivot bolt is located each on the crest between the horizontal in Fig.3 Leg of the swivel bolt and its vertical hook end. The neighborhood of the two locking teeth 24.25 leads to displacements of the wing or the lock case 15 can be avoided down. The hook end of the Swivel bolt 11, 12 cannot therefore reach a position in which the wing and thus the lock case 15 of the Swivel bolts 11, 12 could be separated.

Fig.2 shows that the housing 10 and the bottom plate 21st together with the swivel bolts 11, 12 and the push rod 14 can be pre-assembled into a structural unit by the Swivel lock 11, 12 on the housing pin 20 and the push rod 14 are plugged onto the setting pins 19, after which the base plate 21 placed as the lower housing cover and is fastened with a fastening screw 47. Here engages the fastening screw 47 in a housing pin 20 and clamps the housing 10 with the base plate 21 in such a way that the space 40 for a frictionless as possible Moving the swivel bolt 11, 12 and the push rod 14 required Distance.
