Abstract

The invention relates to a vertical reinforcement element which can be varied such that it can be used on different sash jambs with adaptive effect, irrespective of the design of the jambs and the material they are produced of. For this purpose, the invention proposes a vertical reinforcement element for a sash (1) of a sliding sash that is movable from one plane to a plane parallel to the frame. The vertical reinforcement element has a pin (7, 7') that is connected to a supporting profile (6) of the horizontal jamb (1a) of the sash in such a manner that the pin has a distance (X) at least from the vertical jamb (1b) of the sash. Said pin, on its upper end (7a), has one or more cut-out sections (7c, 8b) for the insertion of respective positioning devices (8, 8') which are used to exert a variable pressure on the upper end of the pin as the vertical reinforcement element.

Description

Adjustable vertical reinforcement

for a removable sliding wing

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 twist that the

Increased effort when closing the wing significantly, is counteracted.

Corner reinforcements of this type are already known, e.g. from EP-A 1 132 562 (HAUTAU) and EP-A 1 391 576 (HAUTAU). These known stiffeners have a fixed,

consistent relationship with 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, can not be collected evenly and comparable.

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 or 10; as a method having the features of claim 11 or 12.

The adjusting means (as adjusting device) at the upper end of the vertical stiffening (of its bolt) acts on this upper end and, thanks to a distance from the

vertical wing spar, a change in the angle between the bolt 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 13) when the insertion area (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 is in the carriage and especially in the Abstellarm for the normal state of non-compensation one

Deviation to recognize 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 such a way that the bolt stands at a clearly positive angle inclined with respect to the surface of the vertical spar, and a parallel position already

Precompensation, which raises the "sagged" horizontal plane in the direction of the real, perpendicular to the frame, hypothetically 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 the

Insertion region of the support profile (claim 12 or 10) that it coincides with the plane perpendicular to the surface of the frame, horizontal plane.

An alternative description of the change in pressure at the top of the

Vertical stiffening is the distance of the upper end of the bolt from the

Change surface of the vertical wing spar, so that a path-controlled torque generation results in the insertion of the support profile, which carries out the compensation. 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 4) is to be understood functionally. He is elongated and stuck in the bottom of the support profile. He brings a torque in the profile. Even an elongated, thick plate fulfills this task. More generally, "the bolt" stands for an elongated one

Torque lever, which is clamped at the bottom and adjusted at the top (in its angular position or its distance from the vertical spar). At the clamping point he exerts its torque (claim 10), 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 includes that it is also form-fitting for a cohesive connection. A one-piece connection, so the immediate attachment of the bolt on the support profile (as a component) is also known as

to understand "at least positively". This is not exclusive, but a consecutive kind of connection. A one-piece (claim 4c) is also achieved by welding or gluing. A riveting process may not produce a one-piece, but is non-positive. All these types of connections are possible, but the insertion into a vertical or slightly inclined insertion in the support profile 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 plugging may be able to produce a higher torque on a larger one

Apply height section of the support profile. It is also conceivable, however, an initially positive connection by plugging with a subsequent additional connection operation of, for example, welding. This combines the stability and resilience of the compound. Instead of welding, gluing can also serve both functions in conjunction with backlash-free insertion.

The other dependent claims are included here.

Further details and advantages of the adjustable vertical bracing can be found in the following description with reference to corresponding examples.

Bolt 7 'cooperates as an actuating element. The figure shows the device from the front.

FIG. 5a,

Figure 5b shows a longitudinal section along the vertical

Sectional plane A-A of Figure 5 in two angular positions of the actuating element as a bolt 7 '.

Figure 5c shows a top view of the device according to

FIG. 5.

FIG. 5d shows the device according to FIG

opposite side (bottom or mounting side). For better understanding, the device according to the examples of the invention is shown in Figures 2 to 4 in its installed state at the right lower corner of the wing 1, where the horizontal spar la and the vertical spar lb of the sash are connected together. This installation state applies correspondingly to the example of FIGS. 5 but is not shown there.

In Figure 1, the sliding panel 1 is shown in its lower portion, where its horizontal spar la is connected to the two vertical bars lb. On the associated

Frame 2 is a running rail 3 fixedly connected to the path 3a, on which the carriages 4 are seated, which are pivotally connected to the sliding leaf via pivoting arms 5 on the horizontal rail la of the casement (non-displaceably) arranged support profile 6 (pivot axis 50). With 7 and 8 aids for vertical stiffening and their adjustment in Figure 1 are indicated.

Figures 2 to 4 show the adjustable stiffener in the vertical section, with the wing frame 2 parked wing 1, each in the same representation, but with different angles et of the bolt 7 relative to the vertical beam lb. This corresponds to different torques in the insertion region 6a of each support profile.

In Figure 2, the carriage 4 is shown with swung-out arm 5 and its connection to the wing on the support section 6. In the latter, in a plug-in opening 6a, the lower section 7b of the elongated section usable for stiffening is free of play

Torque levers 7 plugged. 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 la a plate below the lower spar plate-shaped web 6 'and a profile which fixes the lever 7 in a predetermined, preferably parallel to the contact surface E of the support profile distance "e". Since FIG. 2 shows the device in a first position, which corresponds to a partial compensation, the section of the lever 7 (hereinafter pin 7) which projects freely upwards beyond the support profile is located in a parallel distance X which remains constant from the outer surface of the wing spar lb = e, which for comparison purposes with the other situations shown in FIGS. 3 and 4, in the figure section shown above the end of the bolt 7 is designated as angle et (et is zero in FIG. 2).

The parallel situation of Figure 2 relates to the insertion portion 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 ct. 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 is one

Bore 7c or the like. For the passage of an actuator, such as a in the wing spar lb engaging 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 with respect to the surface E of the support profile 6, the web-shaped section 7a is not completely parallel to the surface of the vertical beam 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.

Partial wing weight compensation, shown in Figure 2, results from the abutment of the head 8 'on the web-shaped portion 7a. Here, a pressure on the web-shaped portion is already applied, which is effected by screwing the screw 8 in the vertical wing spar lb, 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 wing weight Fi, the wing has twisted the stay arm 5 inwards, whereby the left outer end of the wing arm is lower than the said level 500. The center plane of the loaded arm 5 results in 501, the angle shown, ie: Fehlwinkel, 2 already partially compensated in that the screw 8 is screwed and a pressure on the upper web portion 7a applies, whereby the bolt 7 is rotated to the right, with the result of a corresponding torque in the insertion region 6a of the support section. 6

The angle deviation in the load case shown in FIG. 3, which substantially corresponds to the situation where no compensation takes place, becomes more apparent the sash weight Fi can completely affect the bagging position of the extension arm 5 of the carriage 4 (in itself both arms 5 and 4).

In the figure 3, a representation similar to Figure 2, the lower portion of the wing is inclined due to its position and its load F = Fi 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 cti between the bolt 7 and the outer surface of the vertical wing spar lb 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 is clearly shown in FIG. 4, which is shown similar to FIGS. 2 and 3. In the figure 4, the adjusting screw 8 is more attracted and with the help of the corresponding under transverse pressure set upper portion 7a of the bolt 7, the lower spar la 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 shown in Figure 2, 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 et 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 ai of Fig. 3rd

Instead of forces that are applied via the adjusting member 8, and over 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 greater, the image of Figure 3, the distance is smaller, results in the image of Figure 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 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

Height of the wing in the area of the supporting profile leads.

Figure 5 shows a further 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 having 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 contact with the lower wing spar (see Figure 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-going recess 12a, the outline of which is indicated in Figure 5 with 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 A-A in Figure 5

to see both representations in Figures 5a and 5b, as well as in Figure 5d, which is opposite to Figure 5 opposite view of

Vertical stiffening with associated adjustment device shows.

FIG. 5c shows the arrangement according to FIG. 5 in the vertical direction of view 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.

Figure 5a shows the device in a neutral (parallel) functional position in which the mounting plate 9 with the bolt 7 'forms an angle zero (parallel position). FIG. 5b shows the device in a prestressed position, in which the threaded bolt 8a is 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 was illustrated with the figure 5b. The resting of the bolt on the

Pressing (on the right side of FIGS. 5a and 5b) causes the bolt to pivot although it has no 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 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 should be noted that his head 8a 'from the rear, ie

wing frame side is inserted through the plate 9 and after mounting the plate still has enough clearance, so that the bolt can be rotated. The

Rotation is achieved by engaging a tool in an opening profile 8d in FIG

Axial direction of the bolt causes, which may 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 levers to the plate 9 in the upper part and gives a changed

Torque in the lower region of the torque lever as a bolt 7 ', where it sits in the support section 6 (its insertion region 6a).

Both of the embodiments shown in FIGS. 1 to 4 and 5 make it clear that they allow the device to be easily assembled before or after assembly 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 in each application

Corner reinforcement and thus a compensation of the higher effort in the

Close the parked wing.
