EP2175098B1 - Load alleviation assembly for a window, door or similar - Google Patents

Description

The invention relates to a relief arrangement, with which at least a part of the wing load of a wing of a window, a door or the like is transferable to a fixed enclosure, with a surround-side and a wing-side abutment and arranged between the abutments load transfer element, wherein at least one of the abutment a stationary abutment part and a relative to the fixed abutment part movable abutment part and between the abutment parts a spring arrangement is arranged.

From the EP 1 837 472 A1 is a window, a door or the like having a fixed skirt and an openable and closable wing, with a wing load transfer device for introducing at least a part of the wing load into the fixed enclosure, a facing side and a wing side abutment arrangement for supporting a load transfer means and one therewith cooperating, a occurring during an opening and closing operation of the wing distance change between the abutment assemblies compensating distance compensation device known. The distance compensation device comprises a spring arrangement, which always causes a vertically acting spring force component which is directed counter to a vertical weight force component of the weight force of the wing or the wing load and is always smaller than the vertical weight force component.

In this wing load-carrying device, the part of the wing load-carrying device which has the spring arrangement must be installed so accurately that in use the spring arrangement has the correct pretension. Furthermore, not only the wing itself must be placed on a corner bearing during assembly of the wing, but also the load transfer means must be properly positioned, which makes installation difficult.

From the unpublished German patent application DE 10 2007 024 742.9 It is known to provide a toggle lever in a relief arrangement for a window, a door or the like, with which the bias of the spring assembly can be subsequently generated. In this device, however, a user has no information as to whether the correct bias voltage has been generated.

From the DE 588 193 is a door closer, consisting of a rear door slit crossing, longitudinally adjustable rod known which is mounted at one end to the door and at the other end to the door frame ball joint-like and when opening the door lifts them, wherein on the lower end of the rod For example, by means of an adjusting nut more or less compressible spring is arranged, which is supported with its lower end against the stationary arranged lower bearing.

It is therefore an object of the present invention to provide a relief arrangement which, even with somewhat inaccurate mounting of the relief arrangement or parts thereof, allows to set and control the correct bias of the spring arrangement.

This object is achieved by a discharge arrangement with the features of claim 1. By the display can be monitored whether the spring assembly was set under a bias at all and whether the bias is sufficient to remove at least a portion of the wing load by the relief arrangement and thus to partially relieve a corner bearing from the wing load.

The tension indicator can be designed as an optical or acoustic display. For example, when the correct voltage is reached, an LED may light up or an acoustic signal may be given.

In a particularly preferred embodiment it can be provided that one of the abutment parts at least one viewing window, for. B. has an opening. Through the viewing window can be controlled whether the spring assembly or a part on which the spring assembly is supported, in the correct position, that is, in a position indicating that the spring assembly has the correct bias. Preferably, the bias voltage is infinitely adjustable. The viewing window is also considered as a visual display. It can be provided on the movable or the stationary abutment part. The Fixed abutment part may also have two viewing windows, which can be monitored via a viewing window, the position of the movable abutment part and the other window of the voltage state. The movable abutment part and / or the part of the spring assembly, which must appear in the viewing window in the correct stress state or the part on which the spring assembly is supported, a signal color, for. B. red or yellow, to be more visible. The one or more viewing windows may be formed as inclined slots or as a simple passage openings, in particular through holes.

Furthermore, it can be provided that the fixed abutment part and the spring arrangement or the movable abutment part each have a mark or the like. The marking can be, for example, the end of the spring arrangement or an edge, or an edge of a part, on which the spring arrangement is supported. The marking of the stationary Abutment may for example be the viewing window or a slot of the viewing window. However, other markings, such as horizontal dashes, are conceivable that must be made to match so that the spring assembly has the correct bias.

Advantageously, a clamping mechanism for generating a bias of the spring assembly is provided. The tensioning mechanism is preferably part of the relief arrangement. However, an external clamping mechanism can also be used. The tensioned spring arrangement must then be suitably fixed in the clamping position.

Particular advantages arise when the clamping mechanism comprises an adjusting screw which can be screwed into the fixed abutment part and acts at least indirectly on the spring arrangement. By a screw gradually a bias voltage can be generated and can be generated and adjusted by a correspondingly wide screwing the screw preload. In particular, the adjusting screw can be screwed in until indicated by the tension indicator that the correct bias is present. A particular advantage is that the fixed abutment part does not have to be positioned accurately, but can be mounted in the vertical direction at different locations, or with a certain tolerance on the wing. By screwing in the set screw, the correct preload can still be set.

The set screw may act on a tapered pin or pin portion. The pin or pin portion may cooperate with an element on which the spring assembly is supported. Thus, if the pin is adjusted in position via the adjusting screw, the bias of the spring arrangement is also changed.

Characterized in that according to the invention a tension indicator is provided to indicate the state of stress, the discharge arrangement or at least the load transfer element can be used later, for example, if the wing is already placed on the corner bearing fitting. Although the Ecklagerbeschlag briefly absorb the full wing load, but the assembly is relieved, since only the Ecklagerbeschlag must be brought into line with the wing and not additionally the load transfer element during assembly of the wing must be aligned. Due to the fact that the spring arrangement can only be put under tension later when the load transfer element has been mounted, this procedure is possible.

Further advantages are obtained when the pin is guided in the stationarily arranged abutment part and penetrates the spring arrangement. In this case, the spring arrangement can be supported on a part of the pin and on the stationary abutment part.

The diameter of the pin may be in a section in the range of the diameter of the screw. In particular, the pin may have a slightly smaller diameter than the set screw in a section. As a result, the stationary abutment part can be produced very easily. A thread can be cut into an opening or hole so that the adjusting screw can be screwed into it. At the same time, the bore can serve as a guide for the pin in one section and the adjusting screw can act directly on the pin.

The pin may have a radial thickening, on which the spring arrangement is supported. For example, the spring assembly may be supported at the top of the radial thickening and at the bottom of a portion of the fixed abutment member. The adjusting screw can act from above on the pin and thus put the spring assembly under pretension.

If the movable abutment part is arranged captive on the stationary abutment part, the assembly is particularly simple because the movable abutment part does not need to be held and fixed separately while the wing is mounted. For example, an embossment may be provided on the movable abutment part, which prevents the movable abutment part from coming off the stationary abutment part.

The load transfer element may be formed as a rod having at least one ball head, which is clipped into the movable abutment part.

As a result, the connection of the load transfer element with the movable abutment part is particularly simple. In addition, the load transfer element is movable relative to the movable abutment part in many degrees of freedom.

It can be provided that the border-side abutment is supported on a Ecklagerbeschlag the window, the door or the like. Thus, the load, which is removed by the relief arrangement, from above, for example, on the base plate of the Ecklagerbeschlags, in particular a turn-tilt fitting, act and prevent the Ecklagerbeschlag tilts due to the weight of the wing. The Ecklagerbeschlag can be stabilized. But it may also be provided in particular in wood or plastic windows that the load is removed from the base plate and from the vertical part of the window frame. The relief device can also be designed as a claimable on train relief device.

The clamping mechanism of the relief arrangement can be formed in various ways. For example, the clamping mechanism may include a toggle or an eccentric. As a result, the clamping mechanism can be configured in a mechanically particularly simple manner. Furthermore, it can be provided that the clamping mechanism comprises two hingedly interconnected rods. In the relaxed state, the rods can have an angle <180 ° to each other. In the tensioned state of the spring arrangement, they preferably have an angle of 180 ° to each other, wherein they are fixable to each other in this position, for. B. by a union nut.

According to an alternative embodiment it can be provided that the clamping mechanism comprises one or more slides. By the slide, a pin or pin portion, which is supported on the spring assembly, relative to the fixed abutment displaced and fixed in this position. The shift can be done stepwise by several slides. In this context, a screw or a threaded pin is considered as a slide.

According to an alternative embodiment it can be provided that the clamping mechanism has a bevel gear. As a result, the preload can be adjusted precisely with little effort. According to a further embodiment it can be provided that the load transfer element is designed to be variable in length. This also allows the bias voltage to be changed.

The scope of the invention also includes a window, a door or the like with a turn-tilt fitting and a relief arrangement according to the invention.

It is particularly preferred if the discharge arrangement is separated from the tilt and turn fitting. This means that the discharge arrangement can also be used subsequently with a conventional turn and / or tilt and turn fitting and thus can be retrofitted.

Further features and advantages of the invention will become apparent from the following description of embodiments of the invention, based on the figures of the drawing show the essential to the invention details, and from the claims. The individual features can be realized individually for themselves or for several in any combination in a variant of the invention.

Fig.1 shows the wing-side part of a relief assembly 10, with a wing-side abutment 11, which comprises a fixedly arranged abutment member 12 and a relatively movable abutment member 13. The stationarily arranged abutment part 12 can be fixed in the embodiment shown four punching screws on a wing stationary. In particular, the fixed abutment part 12 is designed to be used on an aluminum window. By the four screws 14 -17 of the groove overhang can be pushed away, which overhangs the guide 18, 19. This means that the stationary abutment part 12 can be inserted and fixed in a fitting part groove of an aluminum window. Between the movable abutment part 13 and the stationary abutment part 12, a spring arrangement 21 is arranged, which in the FIG. 1 is relaxed. By a screw 22, a bias of the spring assembly 21 can be generated. The spring assembly 21 is executed in the embodiment by a plurality of disc springs, but can also be realized differently, for example by a coil spring or the like.

In the in the FIG. 2 shown position, the adjusting screw 22 is screwed into the stationary abutment member 12, so that a pin portion 23 and a protruding from the pin radial projection 24 has been moved in the direction of the movable abutment member 13. The abutment part 13 is supported via the load transfer element 20 on a mount-side abutment. By compressing the spring assembly 21, a part of the wing load is transmitted to the surround-side abutment. The movable abutment part 13 has a viewing window 25 with a slot 26, so that a mark is visible, which indicates whether the spring assembly 21 has the correct bias.

The FIG. 3 shows a sectional view of the part of the discharge assembly 10 according to FIG. 1 , It can be seen that the spring arrangement 21 on the one hand the movable abutment part 13 is supported. At the other end, it is supported on the radial projection 24. The movable abutment part 13 is guided on the stationary abutment part 12 and movable relative thereto.

A pin 30 penetrates the spring assembly 21. The pin 30 has the radial projection 24 and the pin portion 23. The end 31 of the pin 30 represents a mark that must be in the viewing window 25 when a sufficient bias of the spring assembly 21 has been generated. To generate the bias, the adjusting screw 22 is provided, which is screwed into the stationary abutment member 12 while acting on the pin portion 23 and displaced in the direction of the movable abutment portion 13. The pin portion 23 tapers toward the radial projection 24 and has a similar diameter as the set screw 22, so that it can be connected axially to the set screw 22 in the set screw 32. The pin 30 is guided in the embodiment both in the stationary and in the movable abutment part 12, 13.

In the presentation of the FIG. 4 It can be seen that the adjusting screw 22 has been completely screwed in and thereby the pin 30 has been moved so far that the marker 31 is in the correct position in the viewing window 25. In particular, the marker 31 is located in the slot 26. The spring assembly 21 was compressed. This created a bias voltage.

In the FIG. 5 is a Ecklagerbeschlag 40, in particular a turn-tilt fitting shown having a base plate 41 and two tabs 42, 43. The corner band 44 is placed on the Ecklagerbeschlag 40. The weight of the wing 45 is removed by the Ecklagerbeschlag 40. To relieve the fitting, in particular to prevent tilting of the base plate 41 due to the sash weight, the surround-side abutment 46 is provided, which is mounted on the fixed frame 47 and has a receptacle 48 for the load transfer element 20. The load transfer element 20 has at both ends a ball head, which can be clipped into both the movable abutment part 13 and in the border-side abutment 46. The enclosure-side abutment 46 is supported below on the base plate 41 from or prevents, which tilts the base plate 41 due to the weight of the wing 45.

In the FIGS. 6a, 6b an embodiment is shown in which the clamping mechanism comprises an eccentric 50 which can abut on the pin 30, thereby compressing the spring assembly 21. The eccentric 50 has a notch, which in the clamping position ( Fig. 6b ) comes to rest on the pin 30 frontally. The notch 51 holds the eccentric 50 in the clamping position.

In FIG. 6c the eccentric 50 'is designed as a double eccentric. The eccentric 50 'is rotatably arranged on a vertically movable part 100. When turning the eccentric 50 'as in the FIGS. 6a, b displaced the pin 30 and thereby tensioned the spring assembly 21. At the same time the eccentric 50 'cooperates with the adjusting screw 101, whereby the part 100 is moved downward and the spring assembly 21 is additionally tensioned. By adjusting screw 101, a fine adjustment of the tension of the spring assembly 21 can be carried out.

The Indian Figure 7a shown clamping mechanism has two hingedly interconnected rods 52, 53. For tensioning the spring assembly 21, the rods 52, 53 in the in Fig. 7b shown position. The rods 52, 53 are fixed in this position by a union nut 54, which is pushed over the joint 56. The rod 53 has a larger diameter than the rod 52, so that the union nut 54 in the position according to Fig. 7b is held. However, one of the rods 52, 53 could also have an external thread, so that the union nut 54, which would have to have an internal thread, can be fixed in different positions.

The Indian FIG. 8 shown clamping mechanism has an eccentric 57 with a lever 58. By the eccentric 57, the clamping element 21 can be tensioned.

In the FIGS. 9a, 9b a clamping mechanism is shown by means of a toggle lever 59. This is supported on a stop 60. The rods 59 ', 59 "can be interconnected with each other or laterally articulated Status ( Fig. 9b ) a backup is necessary. For example, a pin can be inserted into the openings 55a, b in the direction of arrow 55c, or the rods 59 ', 59 "can be encompassed by a securing element.

In the FIG. 10 an alternative arrangement of a toggle lever 59 is shown acting on a pin portion 23 to create a bias of the spring assembly 21.

In the FIG. 11 The clamping mechanism has a wedge 61 which is moved along an inclined surface 62 of the stationary abutment part and thereby compresses the spring arrangement 21. It is also conceivable to use several wedges.

The clamping mechanism of Figures 12 a - 12c comprises a plurality of pins or sliders 63, 64, which cooperate with steps 65, 66 of a clamping portion 67. At the clamping section 67, the spring assembly 21 is supported. First, the pin 63, which is arranged obliquely, screwed into the fixed abutment member 12, whereby the clamping chamfer 67 is moved downward. Once the stop 66 is below the tip of the pin 64, this pin can be screwed and thereby the clamping element 67 are further displaced downwards, whereby the bias of the spring assembly 21 is increased.

In the FIG. 13 an embodiment is shown, with which the bias voltage is generated by a part 70 (fixed-frame-side abutment) is moved via a set screw 71. The part 70 is guided axially on the pin 72. If the screw 71 is screwed in, the part 70 moves upward, whereby the spring assembly 21 is compressed. The load transfer element 20 is rigid and has a constant length.

In the embodiment of the FIG. 14 the load transfer element is designed as a two-part support rod, wherein the two parts 75, 76 of the support rod are connected via a connecting element 77, which has a right-hand thread and a left-hand thread. By turning the connecting element 77, the distance between the parts 75, 76 to each other can be changed, whereby the bias of the spring assembly 21 is changed.

The clamping mechanism according to FIG. 15 has a bevel gear 80, wherein in the vertical bevel gear 81, an external thread 82 is provided, on which the pin portion 23, which carries an internal thread in this case, is screwed. When the horizontal bevel gear 83 is driven, the bevel gear 81 rotates, either further screwing the pin portion 23 onto the bevel gear 81 to reduce the bias of the spring assembly 21, or unscrewing the pin portion 23 away from the bevel gear 82, so that the bias voltage the spring assembly 21 is increased.

Fig. 16 and Fig. 17 show the wing-side part of a relief assembly 10, with a wing-side abutment 11, which comprises a fixedly arranged abutment member 12 and a relatively movable abutment member 13. The stationarily arranged abutment part 12 is formed like a housing and receives the movable abutment part 13. The stationary abutment member 12 can be fixed in the embodiment shown four punch screws on a wing stationary. In particular, the fixed abutment part 12 is designed to be used on an aluminum window. Through the four screws 14-17 of the groove overhang can be pushed away, which hangs over a not visible here guide. This means that the stationary abutment part 12 can be inserted and fixed in a fitting part groove of an aluminum window. Between the movable abutment part 13 and the stationary abutment part 12, a spring arrangement 21 is arranged. By a screw 22, a bias of the spring assembly 21 can be generated. The spring assembly 21 is executed in the embodiment by a plurality of disc springs, but can also be realized differently, for example by a coil spring or the like.

The set screw 22 can be screwed into an insert 100 of the stationary abutment part 12, so that a pin portion 23 and a protruding from the pin radial projection 24 is moved in the direction of the movable abutment part 13. The abutment part 13 is supported via the load transfer element 20 on a mount-side abutment. By compressing the spring assembly 21, a part of the wing load is transmitted to the surround-side abutment. The fixed abutment part 12 has two slot-shaped viewing window 25.1, 25.2, so that in the viewing window 25.1 a mark is visible, indicating whether the spring assembly 21 has the correct bias. The viewing window 25.2 is used to control the position of the movable abutment part 13. By the oblique to the longitudinal direction of the abutment 11 alignment of the viewing window 25.1, 25.2 possible tolerances in the installation of the abutment 11 is taken into account.

The FIG. 17 shows a sectional view of the part of the discharge assembly 10 according to FIG. 16 , It can be seen that the spring arrangement 21 is supported on the movable abutment part 13 on the one hand. At the other end, it is supported on the radial projection 24. The movable abutment part 13 is guided on the stationary abutment part 12 and movable relative thereto. By an embossment at the point 101, the movable abutment part 13 is held captive in the stationary abutment part 12.

Fig. 18 shows a plan view of the insert 100, which has four notches 102-105. The indentations 102-105 are further excluded by the screws 14-17. As a result, the insert 100 is rotationally and fixedly fixed in the abutment part 12. He is thus part of the same. The insert 100 is identical in its external dimensions to the abutment part 13. Merely inside, they are designed differently. The parts 100, 13 can be made of signal-colored plastic.

The notches 102-105 are not mandatory. Up to a certain production step, the parts 100, 13 together, can be produced in the same process, or it must be made up for use as insert 100 or abutment part 13 late in the manufacturing process.
