EP2663710B1 - Adjustable vertical reinforcement element for a sliding sash that is movable from one plane to a plane parallel to the frame - Google Patents

Description

The invention relates to a vertical stiffening for the wing of a sliding door or a sliding window (as a method and as a device). The lower, horizontal wing spar is connected to at least one mounted on a running rail on the frame with its rollers carriage via a stay. When you open the wing creates a corresponding torque that generates a significant torsional effect on the lower horizontal spar of the wing with the load of the wing in the open position (= the Parallelabstellung).

A vertical reinforcement requires a corner reinforcement in the drive area of the wing, which counteracts the torsion of the lower wing spar. The torsion, which significantly increases the effort required to close the sash, is thereby counteracted.

Corner reinforcements of this type are already known, for example EP-A 1 132 562 (HAUTAU) and EP-A 1 391 576 (HAUTAU). These known stiffeners have a fixed, consistent relationship to the wing when assembled. This means that the resulting torsion in various wing materials, such as plastic, wood and metal, or different sash weights, z. B. due to the weight of the disc, not even and comparable can be collected.

The DE 20 2008 007 829 discloses a fitting for a sliding wing, in which a display device comprises a bearing and guide plate as a stationary base, on which a control for stopping and moving the wing is provided, which is coupled to an actuating and locking linkage.

The object of the invention is to provide a vertical stiffening, which is adjustable so that it can be used on various spars with adaptive effect, regardless of how the spars of the sash constructed and what material they are made.

This object is solved by the features of claim 1; as a method having the features of claim 9 or 10.

The adjusting means (as adjusting device) at the upper end of the vertical stiffener (its bolt) acts on this upper end and causes, thanks to a distance from the vertical wing spar, a change in the angle between the pin of Vertical stiffening and the vertical wing spar. If, for example, the angle is set to a negative value, the lower horizontal wing spar, together with the carriages assigned to it, rises.

The parallel position of vertical spar and bolt corresponds to the angle zero.

The parallel position is only relative to the wing. It can vary in a small angular range (claim 11) when the insertion region (the insertion opening) is inclined for the bolt, with respect to the plane of the contact surface of the support profile for the horizontal wing spar. This can be done in a range of + - 5 °, preferably + -2 °. The "parallel position" should also rewrite this.

Not perpendicular to the extension of the bolt but is the horizontal plane which is perpendicular to the extension of the window frame. Here, in the carriage and especially in the Abstellarm for the normal state of non-compensation a deviation can be seen by the sagging of the wing. The result is a deviation of the plane, which is the greater, the greater the weight of the wing (possibly including the wing insert, eg a glass pane). A completely uncompensated situation can arise in that the bolt is at a significantly positive angle inclined to the surface of the vertical spar, and a parallel position is already a precompensation, which the "sagged" horizontal plane in the direction of the real, perpendicular to the frame, hypothetical lifting the best horizontal plane. A complete compensation is achieved when the sagged plane has been raised so far (more correctly: twisted), by the influence of a torque in Einsteckbereich the support profile (claim 10 or 8) that it coincides with the plane perpendicular to the surface of the window frame, horizontal plane ,

An alternative way of describing the change in pressure at the upper end of the vertical stiffener is to change the distance of the upper end of the bolt from the surface of the vertical wing spar so as to provide a path controlled torque build-up in the insertion area on the support profile which compensates. This compensation can also be called "distance-controlled bagging compensation", based on the extension arm of the carriage.

The term of the bolt, which may have different cross-sectional shapes (claim 3), is to be understood functionally. He is elongated and stuck in the bottom of the support profile. He brings a torque in the profile. Also an elongated, thick Plate fulfills this task. More generally, "the bolt" means an elongated torque lever that is clamped down and up (in its angular position or distance from the vertical beam). At the clamping point he exerts its torque (claim 8), which can achieve the compensation of the "sagging" of the wing, and this adjustable.

The connection of the bolt with the support profile, at one or both corners, is at least form-fitting according to claim 1. The connection can also be created cohesively or non-positively, which means that it is also form-fitting for a cohesive connection. An integral connection, so the immediate attachment of the bolt on the support section (as a component) is to be understood as "at least form-fitting". This is not exclusive, but a consecutive kind of connection. A one-piece is also achieved by welding or gluing. A riveting process may not produce a one-piece, but is non-positive. All these types of connection are possible, but the insertion into a vertical or slightly inclined insertion in the support section allows the subsequent removal of the bolt. For the stiffening such removal is not mandatory, but also meets the one-piece component in the corner of its task of variable vertical stiffening.

The insertion may be able to apply a higher torque on a larger height portion of the support profile. It is also conceivable, however, an initially positive connection by plugging with a subsequent additional connection process, for example, welding. This combines the stability and resilience of the compound. Instead of welding, gluing in combination with play-free insertion can fulfill both functions.

The other dependent claims are included here.

FIG. 5a, FIG. 5b

FIG. 5c

shows a top view of the device after FIG. 5 ,

FIG. 5d

shows the device after FIG. 5 from the opposite side (bottom or mounting side).

For a better understanding, the device according to the examples of the invention in the FIGS. 2 to 4 shown in their installed state at the right bottom corner of the wing 1, where the horizontal beam 1a and the vertical beam 1b of the sash are connected together. This installation condition applies to the example of Figures 5 accordingly, but is not shown there.

In FIG. 1 the sliding leaf 1 is shown in its lower area, where its horizontal spar 1a is connected to the two vertical bars 1b. On the associated frame 2, a running rail 3 with track 3a is fixedly mounted, on which the carriages 4 sit, which via Ausstellarme 5 with the sliding wing via one on the horizontal spar 1a of the casement fixed (non-displaceable) arranged supporting profile 6 pivotally connected (pivot axis 50) are. With 7 and 8 are tools for vertical bracing and their adjustment in FIG. 1 indicated.

The FIGS. 2 to 4 show the adjustable stiffener in the vertical section, with the window frame 2 turned off wing 1, each in the same representation, but with different angles α of the bolt 7 relative to the vertical beam 1b. This corresponds to different torques in the insertion region 6a of each support profile.

In FIG. 2 is the carriage 4 with swung-out arm 5 and its connection to the wing shown on the support section 6. In the latter, the lower portion 7b of the elongated torque lever 7, which can be used for stiffening, can be inserted without clearance into an insertion opening 6a. This lever is a longer, stronger bolt 7 with a circular or polygonal cross-section.

Each of the two support profiles 6 has, on the side facing the lower spar 1a, a plate-shaped web 6 engaging under the lower spar and a profile which fixes the lever 7 in a predetermined distance "e" parallel to the contact surface E of the carrying profile. There FIG. 2 shows the device in a first position, which corresponds to a partial compensation, is located on the support profile freely upwardly projecting portion of the lever 7 (hereinafter bolt 7) in one of the outer surface of the wing spar 1b constant, parallel distance X = e, for comparison with the others, in the Figures 3 and 4 illustrated situations, in the figure section shown above the end of the bolt 7 is designated as angle α (α is in FIG. 2 Zero).

The parallel situation of FIG. 2 refers to the insertion region 6a, in which the bolt 7 is inserted. The insertion region has a constant distance e when it runs parallel to the surface E of the support profile 6. In further, not shown Embodiments, the insertion region 6a also slightly inclined relative to the surface E extend, for example. In an angular range of -5 ° to + 5 °, preferably ± 2 °, which refers to the orientation and axis of the insertion region 6a, based on the contact surface E. of the supporting profile. e does not change according to the angle α. The axis of the insertion portion 6 a is a portion of the axis 700 of the bolt 7.

At the upper end, the bolt 7 has a (flattened) web-shaped portion 7a, substantially parallel to the outer surface of the spar. In this section, a hole 7c or the like. For the passage of an actuator, such as an engaging in the wing spar 1b screw 8, is provided. The head 8 'of the screw 8 abuts against the outer surface of the web-shaped portion 7a.

If the insertion region 6a is slightly inclined relative to the surface E of the support profile 6, the web-shaped section 7a is not completely parallel to the surface of the vertical spar 1b. Due to its short extension in the vertical direction, it can be assumed that this web section 7a extends substantially parallel to the surface even at an inclined angle of the insertion region 6a.

A partial compensation of the sash weight in FIG. 2 is shown results from the abutment of the head 8 'on the web-shaped portion 7a. Here already a pressure on the web-shaped portion is applied, which is effected by screwing the screw 8 in the vertical wing spar 1b, whereby the lower end of the wing lifts (torque directed to the right, mathematically negative).

Based on the extension arm 5 of the carriage 4, this effect can be illustrated with reference to the two plotted planes 500 and 501, which do not run parallel, but at an angle> 0 are oriented against each other. 500 is the plane that is perpendicular to the vertical plane of the frame 2. She goes through the middle of the stay and runs "ideal". Due to the weight of the wing F ₁ , the wing has twisted the stay arm 5, whereby the left outer end of the wing arm is lower than said level 500. The median plane of the loaded arm 5 results in 501, the angle shown, ie: Fehlwinkel , occupies and in FIG. 2 already partially compensated by the fact that the screw 8 is screwed in and applies a pressure to the upper web portion 7a, whereby the bolt 7 is rotated to the right, with the result of a corresponding torque in the insertion region 6a of the support profile. 6

The angle deviation in the in FIG. 3 shown load case, which corresponds essentially to the situation in which no compensation takes place, ie the sash weight F ₁ can completely affect the bagging position of the extension arm 5 of the carriage 4 (at both arms 5 and 4 wagons).

In the FIG. 3 one to FIG. 2 similar representation, the lower portion of the wing is inclined due to its position and its load F = F ₁ in the direction of the frame 2 and the vertical stiffening is shown in a not yet appropriately compensated position, so that the wing position and the wing load at an angle α ₁ between the bolt 7 and the outer surface of the vertical wing spar 1b lead. This leads to a closing of the wing from its parked position requires a much greater effort. However, this is avoided by an adjustment of the vertical stiffening.

The advantage of the adjustable stiffening clearly shows the FIG. 4 that are similar to FIG. 2 and 3 is shown. In the FIG. 4 the adjusting screw 8 is tightened more and with the help of the appropriately placed under transverse pressure upper portion 7a of the bolt 7, the lower spar 1a of the wing of the frame 2 is rotated away, which greatly facilitates the closing operation of the wing.

The bolt 7 was named as a torque lever and is elongated in geometric form, may be formed as a polygon bolt or round bolt or as an elongated plate. In the partially compensated position, the in FIG. 2 is shown, it is substantially parallel to the surface of the wing. Due to the inclination of the wing to lower due to its weight, the screw head 8 'by itself on the flattening 7a holds and is so far under pressure (contact pressure). Tightening the screw 8 causes the angle α is negative, so the bolt 7 is moved closer to the surface. The distance of the web 7a from the spar 16 is only a ₂ , compared to a ₁ of Fig. 3 ,

Instead of forces that are applied via the adjusting member 8, and on the lever arm 7 as torque in the support section 6 have their effect, can also be talked about ways. The distance a of the flattening 7a from the surface of the wing influences the torque. If the distance is larger, the picture of the FIG. 3 If the distance is smaller, the picture of the FIG. 4 , In other words, this results in a distance-controlled torque, which opens in the support section 6 and is adjustable in size, for adaptation to different wings.

The at the upper end of the bolt as a lever 7 (mutatis mutandis, the entire vertical stiffening) pending pressure can also be understood that at the top End of a displacement adjustment or change in distance relative to the wing happens, which leads to a change in torque and thus to a change in the altitude of the wing in the region of the support profile.

FIG. 5 shows a more developed form of vertical stiffening. This is shown in a front view with a bolt 7 'and its axis 701.

Includes a particularly stable mounting plate 9, which at its lower end two spaced-apart lugs 13, 13 ', which engage during assembly in corresponding receptacles in the support section 6, which is mounted in abutment with the lower wing spar (see FIG. 1 and 4 ). In the upper end region, the mounting plate 9 openings or holes 10 for the passage of screws for securing the upper portion of the vertical wing spar, which are provided in pairs in the "mutual" distance. In the example shown, there are two pairs, which are arranged once in the horizontal and the other in the vertical distance.

The upper end of the mounting plate 9 has at its rear a recess 8a "for receiving the head 8a 'of a strong bolt 8a, to which area on the opposite side of the plate 9 there is provided a raised area 9d of the plate, which is in one in the format and in the thickness fits or correspondingly formed flattening 12b at the upper end 7 * of the bolt 7 '.This bolt has at the location of the flattening a threaded bore 8b corresponding to the thread of the bolt 8a.

On the bolt 7 'opposite side, the plate 9 has a down-expiring recess 12a, whose outline in FIG. 5 is indicated by a dashed line, and in the upper region in the plate 9, an elongated opening 11 is provided. This is also in the - the vertical section AA in FIG. 5 corresponding - both representations in the FIGS. 5a and 5b to see, as well as in FIG. 5d which one compared to FIG. 5 opposite view of the vertical stiffening with associated adjustment shows.

FIG. 5c shows the arrangement according to FIG. 5 in a vertical direction from above with lateral (bent out) projections 9a, 9b. The bolt 7 'is chamfered at the top 7 "and the opposite flattening 12b is visible.

FIG. 5a shows the device in a neutral (parallel) functional position in which the mounting plate 9 with the pin 7 'forms an angle zero (parallel position). FIG. 5b shows the device in a biased position in which the bolt 8 a completely in the threaded bore 8b of the bolt 7 'is screwed in and this inclines to the mounting plate 9. In the inclination, an upper portion immersed in the recess 12 a and the opening 11 of the plate 9 a. The distance 'b' becomes smaller.

In the lower part of the plate 9 is a push-through 9c, which is designed as a contact surface for the pin 7 '. The bolt 7 'is loosely so that it can pivot, as with the FIG. 5b was clarified. The resting of the bolt on the Durchdrückung (on the right side of FIGS. 5a and 5b ) causes the bolt to pivot even though it does not have a bearing. As such, it is held up by the screw bolt 8a and, at least in a form-fitting manner, is inserted in the support profile 6 of the wing.

A lateral guidance of the bolt results from the two projections 9a, 9b of the FIG. 5c (View from above). These two bent tabs, which are bent out of the plate 9, have a distance from each other and are on both sides of the pin 7 'at. This approximately in the middle of the total height of the base plate 9. Thus, the bolt receives the lateral guidance, which also allows pivoting movements. A lateral shearing of the bolt is blocked by these holding elements 9a, 9b. It can thus also transverse forces from the pin 7 'are transmitted to the plate 9.

To the bolt 8a it should be noted that his head 8a 'from the rear, so wing frame side is inserted through the plate 9 and still has enough clearance after mounting the plate, so that the bolt can be rotated. The rotation is caused by an intervention of a tool in an opening profile 8d in the axial direction of the bolt, which can be a polygon and the bolt 8a preferably completely penetrates. Even a front only opening is possible (in the manner of a profiled blind hole).

Other types of engagement of a tool in this bolt, which causes a change of the torque at the lower portion 7b 'of the torque lever as a bolt 7', are possible.

Due to the play of the bolt 8a, the distance "b" of the torque lever to the plate 9 changes in the upper region and results in a changed torque in the lower portion of the torque lever as a bolt 7 ', where this in the support section 6 (its insertion portion 6a ) sits.

Both in the FIGS. 1 to 4 and 5 shown embodiments that make it possible without difficulty, the device before mounting or after the Adjustment in their stiffening effect and thus their corner reinforcement on the affected by the material and the construction of the sash torsion of the lower spar of the wing set in its parked position.

Thus, the device ensures an appropriate corner reinforcement and thus a compensation of the higher force required when closing the parked wing with each application.
