Description

The invention relates to a device for tightening a door leaf or window sash to the frame, which is not visible when the door is closed, comprising a arranged in the fold of the door leaf or frame tightening means, wherein the tightening means in engagement with a arranged in the rebate of the frame or door panel intake block can be brought. D. h., When the tightening device in the fold of the door leaf is arranged, the feed block is corresponding to the fold of the frame and vice versa.

From the US 1,497,815 A a device is known by which a door can be brought into the closed position. Here, a spring-loaded pin with end-side roller is provided on the door leaf visible from the outside, corresponding to the frame of the door an angle is arranged. The angle has an inlet bevel geared to the frame upon which slides the roller of the pin. Here, due to the force of the spring of the pin, the door is tightened to the frame. The device builds voluminous and is already used for optical reasons in the usual house or room doors and certainly not in windows. In addition, there is a risk of pinching fingers and garments, such. As scarves, scarves, etc., since the tightening mechanism already attacks when the door is not yet applied to the frame.

A device for tightening a door or a window to a frame is made of DE 101 08 494 C2 known. This device is characterized in detail by a grab bar having a snap device and a locking hook, wherein the locking hook can be brought into engagement with the tightening latch, wherein either the tightening latch or the locking hook is attached to the door or the frame. The arranged on the door closing hook is moved towards the snap device consisting of the tightening latch and a spring. At the moment when the hook finger reaches an inlet slope, the hook finger is moved against the force of a spring upwards. Here, the hook finger passes a driving collar on the extension latch. Thereafter, the hook finger moves down into an undercut, whereby the locking hook comes into engagement with the extension latch. If now the door continues to move towards the strike plate, passes the locking hook with its inlet slope in the region of the pivotable bolt. In this case, the bolt is brought out of engagement with the extension latch, so that when the extension latch is no longer blocked by the pivotable latch, the pull-out latch moves toward the frame due to the force of two springs, in this case the latch and thus the door attached thereto takes with it and in this way ensures that the door is tightened to the frame.

The device works quite satisfactory, but this is complicated due to the relatively complicated mechanism in the production.

The object underlying the invention is therefore to provide a device for tightening a door leaf or window sash to the respective frame, to the realization of which substantially fewer components are required, and the extent allows a simple installation and is generally inexpensive to manufacture.

To solve the problem is in a device of the type mentioned, in which the tightening device can be brought into engagement with the intake block, proposed that the tightening means comprises a loaded by a spring and displaceable in the vertical direction tightening member, wherein the retraction block has a draw-in slope, and wherein the tightening means includes means for engaging the tightening member with the draw-in slope, the tightening member sliding along the draw-in slope upon engagement with the draw-in slope due to the loading by the spring. The following is clear: The tightening device is located in the fold of the door leaf and is in the closed state z. B. the door is not visible. The feeder block is correspondingly arranged in the fold on the frame of the door or the window, namely the shape that in the closed state of the Door or window, the tightening device and the intake block opposite each other. D. h., The tightening of the door leaf or the window sash to the frame occurs only when the door leaf is substantially already in the closed position to the frame. The arrangement can also be reversed, ie, the intake block is located on the door leaf and the tightening device on the frame. As already stated, the tightening device comprises a tightening member that is slidably received in the vertical direction by the tightening device under the load of a spring. The feeder block has on the one hand a draw-in slope, and on the other hand means for bringing the tightening member into engagement with the draw-in slope. If the tightening member is in engagement with the draw-in slope, then the tightening member tends to move along the slope due to the loading of the spring. Here, the door leaf is then tightened on the door frame or the window sash to the window frame. That is, the draw-in slope is arranged obliquely in the longitudinal direction and thus the height of the door running on the intake block.

Further advantageous embodiments and features of the invention will become apparent from the dependent claims.

Thus, according to a first embodiment, it is provided that the means by which the tightening member can be brought into engagement with the draw-in beveling comprises a triggering member, which is held by a spring in a prestressed position and which in the closed position z. B. the door leaf releases the tightening member. In the open position of the door leaf is held by the trigger member, the tightening member against the force of the spring through which the tightening member is loaded, in a position in which the tightening member is engageable with the draw-in slope. More specifically, with respect to this embodiment, it is provided that the tightening member has a tightening bolt which engages with the Einzugsschräge can be brought. The drawbar, which presents itself as a pin, slides along the draw-in slope, thereby ensuring that the door leaf is tightened against the door frame. To actuate the trigger member to trigger the tightening member from the biased position, a sliding bolt is arranged on the trigger member, which can be brought into contact with the intake block when closing the door. In this case, the trigger member is moved horizontally from the region of the tightening member, with the result that, when the tightening bolt is in the region of the drawbar, due to the spring tension, under which the tightening member and thus the suiting bolt, the door attracted to the door frame becomes.

The feed block has to guide the sliding bolt a corresponding recess, wherein the length of the recess is selected so that the tightening member is released when the tightening bolt of the tightening member is in the region of the drawbar.

The trigger member is under the load of at least one spring acting in the installed state in the horizontal direction, which ensures that when the door is opened, ie when the tightening bolt is moved out of the draw-in slope, the spring acting on the tightening member is thus tensioned by the tightening member , Returns to the starting position, in which the tightening member is held by the trigger member with the door open tense.

According to another second embodiment, it is provided that the retraction block has as a means for transferring the tightening member in engagement with the draw-in slope a longitudinally oriented inlet slope. Here, the intake slope and the inlet slope open into a point, so that inlet slope and draft angle form a triangle. It becomes clear from this: When closing the door, the tightening bar slides along the inlet slope to the tip of the inlet slope in transition to the draft angle. If the tightening bolt reaches the point formed by the inlet slope and the draw-in slope, then it reaches the region of the draw-in slope upon further closing movement of the door leaf, in which case the door leaf is attracted to the door frame due to the force of the spring acting on the tightening element. as previously described. This inlet slope may be provided as an alternative to the arrangement of the trigger member as part of the tightening device or additionally. In any case, the inlet slope also ensures that, for example, when the trigger member has been moved by children into a position in which the tightening member has been released, then during the closing of the tightening bolt by the inlet slope into engagement with the drawbar can be brought.

Advantageously, it is further provided that the spring tension of the spring, under whose load the tightening member is, is adjustable. For this purpose, an adjusting screw is provided in detail, which is mounted within the device in a threaded adjusting block. By turning the screw now the bias of the spring can be adjusted. To be able to adjust the screw, located in the region of the screw head a recess in the device receiving cover plate or the fold of the door or window sash, for example, by means of a Allen key to screw the screw head of the screw can. The recess is closed in the cover plate by a cap to the outside.

The trigger member is designed as a variant as a pivotable lever, the spring-loaded in a position according to Fig. 5 is pivotable. The spring is designed as a leg spring, and ensures that, as already executed, the tightening member is held in the biased position, as in Fig. 5 is shown.

In order for the device to operate satisfactorily, it is necessary for the draw-in block and the draw-in device to occupy a specific position in the fold of the door leaf or the frame relative to one another. According to the installation situation, it may be necessary that the intake block and the tightening device must be adjusted in position relative to each other.

For this purpose, it is provided according to a feature of the invention that the feed block in the region of the draw-in slope has an insert which shows a sliding head with at least one draw-in slope, wherein the insert is changeable fixed relative to the intake block in its position. As a result, an adjustment of the position of the inlet or the draft bevel relative to the tightening member of the tightening device is possible in the sense of a height adjustment in the installed state of the door leaf. Specifically, it is provided in this context that the use of a detent in its position is changeable fixed. This means that the insert can be fixed relative to the intake block at certain predetermined intervals.

In detail, the intake block on a floor on which the insert is changeable fixable in its position. Here, latching members are provided on the bottom, which cooperate with corresponding latching openings in the insert.

Another embodiment is characterized in that the draw-in block can be displaceably fixed on a bottom rail along the bottom rail. Instead of the use described above, by its variable position relative to the intake block, the position of the Inclined slope and the inlet slope in the direction of the length of the fold is variable, can now be adjusted by the fact that now the feed block is displaceable relative to the bottom rail, the entire intake block in its position relative to the tightening member. Such an option is always of interest if z. B. the recess for receiving the sliding bolt in the intake block is not aligned with the sliding bolt, and possibly even the tightening member can not get into engagement with the inlet slope. For these cases, the variability of the position of the intake block on the bottom rail has proved to be advantageous in the folding longitudinal direction.

To move the intake block on the bottom rail, an adjustment is provided in detail, for example in the form of a screw which is mounted in a corresponding arranged on the bottom rail Bock with internal thread. The screw itself is at the end connected to the intake block in such a way that upon adjustment of the screw of the intake block along the bottom rail is movable.

For fixing the intake block on the bottom rail side guides are also provided, which detect the intake block on the top.

According to Fig.1 the door frame is designated 1. The door frame has a fold 2, wherein within the fold the door lock 3 can be found, and on both sides of the door lock at the top and bottom of the door in the installed state in each case a feed block 10th

From the Fig. 2 results in the representation of the door leaf 5 with the fold 6, wherein arranged in the region of the fold 6 by the cover plate 23, 123, the tightening device 20, 120 is located. The arrangement of the tightening device 20, 120 in the fold 6 of the door leaf corresponds to the arrangement of the respective intake block 10, 110 in the fold 2 of the door frame. This means that the intake block 10, 110 and the tightening device 20, 120 in the closed state of the door directly opposite each other.

The design of the intake block 10, 110 results in detail in the view of Fig. 3 , The intake block 10, 110 in this case has a recess 11, 111, wherein the formation of the intake block 10, 110 with an inlet slope 12, 112 and the intake slope 13, 113 results in the upper region of the recess. Above the intake bevel 13, 113 or also the inlet bevel 12, 112, the recess 15, 115 is located in the intake block 10, 110.
Looking now at the Fig. 4 with the representation of a first embodiment, it follows with respect to the tightening device 20, which is shown there without cover, the following: The tightening device 20 takes in the direction of arrow 30, ie in the longitudinal direction of the door, slidably on the tightening member 21. The tightening member 21 has a finger 22 which is in contact with the trigger member designated 25. The trigger member 25 is under the load of the horizontally acting springs 26 which press the trigger member in the direction of the arrow 40. The tightening member 21 is also under the load of a spring, namely the load of the spring 27, which ensures the movement of the tightening member 21 in the direction of the arrow 30. The tightening member 21 also shows the tightening bar 28, which is designed in the manner of a pin and from the plane of the drawing Fig. 4 emerges. The trigger member 25 has the sliding bolt 29, which is also designed in the manner of a pin and emerges from the plane of the drawing.

The operation of the device for attracting a door leaf to a door frame or in the same manner for tightening a window sash to a window frame, is as follows:

The tightening device 20 according to Fig. 4 is shown in the preloaded position. That is, the attraction member 21 is held under the load of the spring 27 by the trigger member 25. If the tightening device 20 is brought to coincide with the intake block 10, The length of the recess 15 is selected such that when the tightening bolt 28 is located shortly after the transition from the inlet slope 12 to the intake slope 13, the trigger member 25 releases the tightening member 21, with the result that the tightening member 21 moves in the direction of the arrow 30 due to the spring 27, with the result that the tightening bolt 28 slides along the draw-in slope 13. This is shown by a dash-dotted representation of the Anzugsriegels 28 on the drawbar 13. Is the suit bolt 28 in the in Fig. 4 upper end position of the draw-in bevel 13, then the door leaf 5 is fully attracted to the door frame 1.

When you open the door of the suit bar 28 in the opposite direction to the drawbar 13 in Fig. 4 down in the direction of the transition to the inlet slope 12 via the tip 13 a. In this case, the sliding bolt 29 comes out of contact with the recess 15, which means that the trigger member 25 in the position according to Fig. 4 is transferred back. That is, the tightening member 21 is again under bias of the spring 27, then to ensure in a renewed closing operation by the tightening bolt 28 that the door is tightened to the door frame.

If one now imagines that the trigger member 25 has been displaced manually in the open position of the door leaf opposite to the direction of the arrow 40, then the tightening member 21 will move in the direction of the arrow 30. During a closing operation, however, the tightening bolt 28 will then slide along the inlet bevel 12, in this case biasing the spring 27 of the tightening member 21, passing through the tip 13a, in order to then again reach the area of the draw-in slope. From this it is clear that the device is tamper-proof.

An advantage of the inventive design of a device for tightening the door leaf or window sash to the respective frame is in particular that protrude little parts on the fold of the door leaf. There are only in front of the sliding bolt 29 and the suit bolt 28, as is in the view of Fig. 2 can be seen very clearly.
That is, the appearance of the door as such is not substantially affected by the device according to the invention.

The embodiment according to the FIGS. 5 and 6 does not differ in its function from the representation according to Fig. 4 , Different is the design of individual components and the possibility of adjusting the tension of the spring 127 of the tightening member. The reference numerals are opposite to the embodiment of Fig. 4 changed. This is preceded by, as shown in the illustration Fig. 5 also a retraction block 110, which has a recess 115 for the sliding bolt 129 when they are moved towards each other (arrow 40). Below the recess 115 is the inlet bevel 112, and the intake bevel 113, which are at an angle of almost 90 ° to form a tip 113a to each other. The draft bevel 113 ultimately serves, in cooperation with the pin-shaped tightening bar 128, to attract the door leaf to the frame. The tightening bolt 128 is part of the tightening member 121 of the tightening device 120, wherein the tightening member 121 is under the load of the spring 127. The device further shows a control block 124a with a set screw 124, through which the bias of the spring 127 is variable. In order to turn the adjusting screw 124, a recess 135 is provided in the region of the head of the screw, which, as befits Fig. 6 results, by a cap 136 on the cover plate 123 is closed. The sliding bolt 129 is located in the illustration according to Fig. 5 on an approximately triangular, pivotally mounted about an axis 139 designed as a lever trigger member 125, wherein the trigger member 125 is loaded on one side by a leg spring 126 such that the trained as a pivotable lever trigger member 125 always has the tendency in the position according to Fig. 5 to transition, in which the tightening member 121 is locked. The tightening member 121 is in this case by the finger 122 with the tightening member 125 in connection. To trigger the tightening member 121, the trigger member 125 pivots against the force of the leg spring 126 in the direction of the arrow 130 when entering the recess 115. The tightening member then shifts in the direction of the arrow 30, as already described in relation to FIG Fig. 4 has been described.

The in Fig. 7 shown intake block 110 is provided with a bottom 140. In the area of the draw-in bevel 113 and the inlet bevel 112, an insert 150 is provided between the floor 140 and the draw-in block 110. The insert 150 shows a sliding head 151, which is provided with an inlet slope 152 and a draw-in slope 153, which run parallel to the draw-in slope 113 and the inlet slope 112, respectively. By a latch 145, the insert 150 can be fixed to the floor 140. The detent 145 includes in the insert 150 arranged latching openings 155 which cooperate with correspondingly arranged on the bottom 140 locking members 146. The adjustability results directly in the view of the FIGS. 7a, 7b ,

The representation according to the FIGS. 8a and 8b is characterized in that the intake block 10 is displaceably mounted on a bottom rail 160 along the arrow 180. In other words, the floor rail 160 has a longitudinal extent which is greater than the longitudinal extension of the draw-in block 10. An adjusting device 170 is provided for adjusting the draw-in block 10 on the floor rail 160. The adjusting device 170 comprises a bracket 175 with a thread 171 for receiving a screw 176, the end with the intake block 10th connected is. The block 175 is supported in a groove-shaped recess 17, so that the draw block 10 is guided laterally by the block 175. On the bottom rail 160, the intake block 10 is further guided by the bottom rail guides 165, 166, wherein the guides 165, 166 detect the intake block 10 on the top 10 a, as can be seen directly in view of Fig. 8a results.
It has been found that the adjustability of the intake block 10 on the bottom rail 160 should be about +/- 7mm.

It should be mentioned at this point that at z. B. three of the devices according to the invention distributed over the length or height of the door, can be dispensed with the lock in the middle of the door.
