EP2216472B1 - Compact carriage for a leaf and method for longitudinal movement of the leaf in a parallel stored position - Google Patents

Description

The invention relates to improvements on a carriage (claim 1) for a wing on a window or a door. This wing is to move in the longitudinal direction and thereby has a parallel-parked layer (claim 10)

From the storage position of the wing is moved to a salaried, also parallel position to close the window or the door. The wing moves (in a working process) by means of at least two carriages, each having at least two rollers, and which support the wing in its movement movable (claim 10).

The claimed invention improves known carriages, which improvement contributes significantly to the claimed carriage has a lower overall height and a higher payload for even higher and heavier wings. It can carry weights of up to 200 kg in the double version and up to 160 kg in the standard version. The rollers are large enough, based on the housing of the trolley, which accommodates them, so that a smooth running characteristic can be achieved. They are concealed and the whole carriage, despite its compact design with a considerable Ausstellweg of up to 125 mm for the wing (in the parallel-parked position) able to work.

Solutions of the prior art are particularly in the DE-A1 32 34 677 and associated EP-B1 103 725 (from GU ), in which two carriages with Abstellarmen move a wing in parallel-parked position, and the salaried position of the Ausstellarmes in the local FIGS. 4 and 5 will be shown. The extension arm is bent and the control arm, there 19, is straight. The carriage itself has a leading control section, there 23, and can be locked in the closed position with a spring loaded by a locking member 39 which acts on the Ausstellarm.

Another solution is the EP-B1 201 717 (from GU ), which with two elongated, straight Ausstellarmen to there FIG. 5 is working. These two arms are pivotally mounted on a carriage and connected by a coupling rod, there 25. They also have the forward projecting from a carriage control section, there 21,22,23 in FIG. 3 , And the triggering of a locked position of a guide joint 21 to the control arm 19 is realized by a receptacle above the running rail, in which engages the downwardly projecting guide pin 21, see. to the first mentioned document from GU, there FIG. 4 with the projection 23 for controlling, the down projecting guide pin 21 and the receptacle 32, which is arranged in a frame mounted on the frame and designed so that the free end of the control arm there at the moment comes to rest when the lower end of the locking bolt against an edge of the trigger gap or slot, there 32, strikes. The exit of the local locking member 21 as a bolt, which projects downwards, allows the Relativverschwenkung the lower Ausstellarms and the pivoting back of the wing against the fixed frame (frame), see. column 7, line 46 to column 8, line 23.

As far as there, as well as here, the wing not only held by carriages at the bottom, is guided and moved, but also provided at the upper end of the wing movable scissor members for guiding the wing, should not be specifically referred to this, but the Focusing the invention claimed here are placed on the lower part of a wing, namely the geometry and design of the or the carriages, which are compared to the prior art, as described above, to improve.

With a leading control section on the carriage housing works the EP-B1 619 410 (HAUTAU ), there FIG. 1 , Two Ausstellarme are pivotally mounted on the carriage, which has a plate-shaped projection 5 as a control section in which a bolt which projects downwardly, is guided in a slot 4. Both arms are straight and elongated, none of them is curved. The Ausstellweg, which can reach the wing between a closed position and an open position by swinging the main Ausstellarmes, is in the local FIG. 3 explained. The local main extension arm 10 is shown in the local Ausschwenklage. The other extension arm abuts on a spring member which is arranged on the main extension arm and holds the bolt in a fixed or latching position in an angled end portion of the slot 5.

A problem of the claimed invention is to make the carriage compact and powerful at the same time. The performance concerns both the ability to record high power and thus large sash weights to lead in parallel-parked position and at the same time take a non-large design, the narrow and elegant fitted in the closed position in a low construction area below the wing and on the Running track can be moved. The Ausstellweg, so the ability of the carriage to space a wing of the fixed frame should be large. So all the requirements of the carriage should be made to be powerful and compact at the same time.

The claimed carriage (claim 1) moves the (not claimed here) wings in a parallel-parked position. It has a compact design or should have a compact design. The rollers that move it can be designed to be large relative to the housing area, that is, occupy at least 90% to 95% of the overall height of the housing area. Preferably, the rollers are not accessible from above and the housing portion is closed at the top to cover the rollers from above.

The rollers are arranged in a housing area. This has a bearing point with which the extension arm is pivotally mounted on the housing portion. The Ausstellarm is the main arm, which receives the load of the wing and keeps this in the parallel-parked position, spaced around the large Ausstellweg, relative to the fixed frame (as a frame). For this purpose, the extension arm has a remote bearing point with which the wing is held and stored. A storage point closer to the bearing area on the housing area is provided for the one end of a control arm, which controls the movement of the extension arm. Said control arm also has another end portion which is guided in a control portion extending longitudinally from the housing portion. This control section has a guide which guides said "further" end portion of the control arm and dictates a particular movement of the arms.

In a summary, two pivotable arms (as a handlebar) and a housing portion are described (claim 1), wherein a control portion controls the movement of the arms relative to the housing. If so far spoken by a "closed position" (position S) and an open position (position O), so that the swiveled, applied to the housing state of the stay or the parked, the large Ausstellweg and the Parallelabstellung of the wing defining pivoting position of the stay is meant , Indirectly so are the closed position of the wing and the open position of the wing meant here but based on the corresponding positions and pivotal positions of the arms of the carriage, which is claimed without wings. With the wing in common, however, the working method is claimed (claim 10).

Again, it should be mentioned that the scissors guides and several scissor assemblies on the top of the wing require no special explanation, since they are of conventional design and can be read in the prior art. Focus is the claimed carriage and the design of the carriage.

The extension arm may be configured to allow full coverage of the control arm. This is paraphrased with reference to a pivoting plane. The pivot plane is parallel to a horizontal plane. It lies below a top and above a bottom of the stay. The extension arm has a voluminous design which allows surfaces to be defined above and below, and these surfaces can be seen in horizontal extension as planes.

If the two planes (top and bottom) are spaced parallel from the pivoting plane, which is defined by the movement of the control arm, then "from the outside", ie in a view from the outside of the extension arm, the pivoting arm is not visible. It is completely covered, in particular in the closed position, and it is not articulated and moved on or above an upper side of the extension arm and not underneath a lower side of the extension arm.

Arrangements of the prior art usually work with two flat links, which are hinged together, but none of them is configured like a volume and is able to cover the other arm from a visible side, see. EP - A21959 080 (from HAUTAU ), there Fig. 3a and Fig. 4 , The viewing direction from the outside is so circumscribed that it is the side of the stay arm opposite the control handlebar.

In the assembled position of the carriage, this will usually show to the interior of the room, so that the term "outside" must not be confused with the outside of the installation site, but only the reference to the carriage, which is considered as the interior, and the view from the outside is the view of the back of the wings carrying the extension arm.

In a further embodiment, in particular cumulative with the first-mentioned embodiment, a closed position is circumscribed. This layer S, as described above, uses a design of the extension arm. This extension arm has a slot portion (gap portion), which is formed so that the control arm can be accommodated therein in a large part, but at least in sections. This concerns the closed position.

In the open position, the control link is swung out of this slot or gap.

As can be seen, the slot / gap extends in the longitudinal direction of the extension arm and faces the housing region of the carriage. The slot / gap allows the control arm to be received, improves the coverage of the control arm, and additionally provides a locking position (or safety) because the control arm can not move upwardly in the closed position. A Aushebesperre or securing against digging is favored.

The slot or gap has a distance from the top and a distance from the bottom of the volume-formed extension arm. He is not pronounced too strong in the vertical direction, so as not to weaken the carrying capacity of the extension arm over a necessary for the immersion of the control arm degree.

Preferably, this can also be designed so that the slot or gap is limited in the depth direction. As a result, the rigidity and, as a consequence, the carrying capacity of the extension arm be kept high, especially for such weights, as they were given in the description.

An additional barrier against evasive movements upwards (in the vertical direction, perpendicular to the circumscribed horizontal plane) is secured by an upwardly closed control block, which has a retraction opening and above a closed wall or surface, by means of the upwardly projecting projection as preferred bolts achieves this effect (claim 6 at the end).

In the claimed open position (position O relates to the stay, which is pivoted), the leadership of the control arm with the curved / curved end region from below and the triggering of this end region from above (claim 1).

For this purpose, the upwardly projecting projection and the downwardly projecting projection in the sense of a double projection are used, which protrudes from the previously circumscribed pivot plane of the control arm up or down. This projection may preferably be formed as a bolt and more preferably with a sleeve-shaped jacket for friction reduction for guiding and release movement.

The guide from below takes over the control section, which continues in the longitudinal direction of the housing portion of this starting and has a guide, in particular in the form of a deep groove. In this groove engages the downwardly projecting projection and is guided by it. The protruding projection is controlled. Under the control is in particular a trigger to understand in which this projection and with him the curved end portion carrying it and the entire control arm is disengaged or released.

The disengagement or disengagement refers to a releasably engaged position achieved by an angled portion of the guide groove with respect to the downwardly protruding projection. This position O is the raised position for the parallel Abstellbewegung of the wing and holds the control arm, which is engaged on the downwardly projecting projection in the angled portion of the guide groove, the pivotal position of the extension arm constant.

To leave this Ausstelllage and move the wing again in the direction of the window frame, the control arm is triggered from above via the upwardly projecting projection, and this may preferably serve a control block, in which enters the control section and a web-like entrance as one after has downwardly open, blind hole-like recess which detects the downwardly projecting projection during retraction and can move it relative to the control section.

After disengaging or releasing the downwardly projecting protrusion, the latter can be moved back along the guide in the longitudinal direction to allow the adjustment of the extension arm, controlled by the control arm.

The inventive feature distinguishes between the guide and the controller. The guide is from below or in the lower area below the control arm by the downwardly projecting projection of the double projection. The upwardly projecting projection of the double projection is operatively entrusted with a control, which control in particular relates to the heraussteuern from an angled end portion of the guide, and thus the disengagement or release from the position O reaches.

In a further embodiment, the training of leadership is described in more detail. To enable a guide in the sense of a sliding guide in the longitudinal direction with respect to the downwardly projecting projection, the guide is formed as a guide groove, which is open at the top. The guide itself has a non-continuous floor, so it is not completely open down, but partially closed. However, this closing of the groove down is not complete, but not more than sections, to let through holes through which possibly come in the groove come in dirt can fall down.

Falling out can also be facilitated by the fact that the protruding from above into the guide, downwardly projecting projection entrains the pollution and one or the other opening in the bottom feeds, from where they fall out of the guide, preferably at the respective end of the guide. This type of self-cleaning is associated with a stiffening of the control section that carries the guide groove.

The control section, which projects in the longitudinal direction of the housing and continues in this direction, then not only consists of a circumferential wall whose stiffness could not be sufficient, but is stiffened on the bottom side by transverse struts, which can be considered as preferred flat connections as part of the floor ,

Preferably, in the respective end region of the guide groove, the bottom is opened with passage openings.

Cut in the transverse direction results in a U-shaped profile at least in some places in the longitudinal direction of the control section.

The rigidity and safety of the guidance of the control section can be improved. This is also possible if the control section is advanced or upstream, and can not be stiffened laterally, above or below by other housing sections.

Another embodiment is the construction of the control section for controlling the control arm. For further control, a control block is added, which is arranged separately at the end of the track on the track profile. The feature is based in its function of the locked position of the control arm, ie such a situation in which at one end of the guide of the control section, the here lying end of the control arm is engaged.

The latch is a releasable latch and the release is accomplished by retrieving from one end of the guide, which end is an angled end as an end portion, relative to the longitudinal extent of the main component of the guide as a guide groove.

The control section is slim and ahead designed so that it can engage at the end of the travel path of the carriage in a transversely continuous recording of the control block. He not only intervenes, but also through this transversely continuous (laterally open) recording.

In a temporal end portion of the passage of this slender, nose-shaped control section, the control block begins to act from above. It is designed so that it is able to extract the control arm from its latched position from above, acting out of the angled end region of the guide.

The training for steering out is preferably formed as a web-like entrance, which is open to the side, inclined and is closed at the top by a wall, which wall can affect the entire top of the control block.

A volume design of the extension is preferred. The volume design is a physically thick, strong training, which is not a plate-shaped design of a handlebar, but designed as a volumetric arm considerably thicker than the relatively flat, reminiscent of a plate shape control arm, but in addition by features that are in the height direction extend and are directed in the longitudinal direction, can amplify. Even with this gain, however, he remains a plate-shaped handlebar, in contrast to the volume-shaped extension arm.

At least in the position O, so the swung-out position (position or "position") is the Ausstellarm straight. He has a bend in the storage area, but in the open position is not visible and remains within the housing area. On the other hand, the control arm has a straight portion and a curved portion, which curved portion is directed to the control portion. This makes it possible to cover the control arm, apply high load and yet to achieve a compact design of the carriage with Ausstellarmen.

In yet another embodiment, which may also be cumulatively seen with one or more of the foregoing features, the double stud is explicitly described, which is located at the end portion of the control link, which end portion is the "other" end portion of the third aspect of claim 1 is assigned to the management of the control section.

The double pin protrudes upwards and downwards as a projection, wherein the under projection for guiding and the upper projection for releasing from the locked position is provided. The locked position is the position O with parallel-off wing.

The effect of the two-sided double bolt is clearly expressed here. From above (from the control block) is triggered, and from below or "below" is guided (in the control section). In the assembly region of the double pin, which is preferably attached to the end region in the form of the curved portion of the control arm, there results a circumferential collar, which projects beyond the dimensions of the control pin in the radial direction. This covenant is described in even greater detail for other purposes.

A releasably engaged position (claim 2) is achieved by the downwardly projecting projection in an angled end portion of the guide. This position can be secured, for which a spring element is used, which exerts pressure or force in the horizontal direction. This force is exerted on the bent portion as a front end portion thereof via a side plate projection. The force acts at least partially in the direction of the angled path section.

The spring element itself can be exchangeable (claim 14). It is functionally provided with a holding portion which is rectilinear, and then preferably extends in a semi-arc to be received in a chamber which may have an undercut to latchingly position the free end of the retaining portion of the spring member. The chamber may be open at the top to release this latching of the spring so that it can be replaced.

Preferably, the pressure applying portion of this spring element is bent to have an outward, directed towards the curved end portion of the control arm camber.

In addition to the spring force and its securing effect, an overarching portion of the housing portion may be provided, which engages over the lateral plate projection of the curved control section (claim 2).

This attack can be present in the locked position, and it is also present, while the control arm with the upwardly projecting pin is controlled out of the control block from the locked position, and is received in its holding action by the control block and its web-shaped entrance.

The change of Einrastlage on the control section towards the control block on the frame is secured by the cross-section (claim 2). A disengagement or falling up is thereby effectively prevented.

At another point of the housing portion, in one end portion may be provided an upper spring piece, which is displaceable in the transverse direction (claim 3).

This spring piece is at least partially plate-shaped and preferably has two locking positions (claim 4). A farther outboard, and a farther inboard.

The spring piece supports the securing position of the carriage in the inserted position in the profiled carriage rail. The carriage is thereby initially tilted, and used by an inwardly moved rotation in the sense of an insertion-tilting movement in the carriage rail, guided on the carriage rollers, which form the instantaneous pivot point. For this purpose, the carriage has a minimum distance from an upper, overarching portion of the carriage rail to perform this pivoting movement can. A locking projection of the housing portion engages under this cross-section, however, needed for pivoting the gap.

When inserted, the gap left free is disturbing. It is thereby reduced in size, that the spring is inserted and at least reduces the gap in height.

The shift can be from a detent position of the spring piece in another, further inside (to the carriage rail) lying detent position of the same spring piece.

If the car is to be removed again, the spring is moved back outwards to swing out the carriage with an oppositely directed tilting movement of the carriage rail and remove it.

The extension arm can be created in its pivoted position as a layer S close to the housing area. A bulbous bulge in a side region of the control section, which is angled relative to the longitudinal guide, is thereby received in a bay-shaped recess of the extension arm (claim 7).

Preferred height and height relations relate to the height of the stay (claim 9) and the strength of the extension arm relative to the control arm (claim 8).

Preferred embodiments of the projections are pin pieces (claim 11). The control block is preferably closed on the top, by a wall with a top (claim 12).

The carriage is defined by the beginning of claim 10 three paintings by two arms and a housing portion, supplemented by a control section. The control section controls the control arm and receives a downwardly projecting projection to the sliding longitudinal guide. The upwardly projecting projection is actuated by a control block, so controlled, at the end of a travel path of the carriage. While the control portion engages a receptacle of the control block engages at the end of this first engagement of the upstanding projection in a web-like, inclined entrance of the control block, and moves the curved / bent portion of the arm and thus the entire control arm from the retracted position out.

This retrieval is done by a return from above and a guide from below. So that the control section can enter the control block and this is not too voluminous form, the control section is described as a nose-shaped slender. Accordingly, it is meant a very long nose, which is slim in length relative to its cross-sectional dimension. The control block itself is to be mounted on the running frame on the running rail in the side facing the space inside and stands in the longitudinal direction in the travel path of the carriage, or its housing area. It is located above the track for the rollers and forms the end of the travel of the carriage with the position O of the Abstellarms. It controls the control arm out of the retracted position via the protruding projection, so that the carriage can move back in the opposite direction on the rollers, the projection in the web-like entrance of the control block is reliably received and remains, and the stay, controlled by the Control arm in the

Location S moved back. The sash approaches the frame and the closed position.

Due to the design of the volume configured Ausstellarms the carrying capacity can be ensured, while covering the visible side, when the slot a part, in itself receives a substantial portion of the control arm, and the slot does not extend completely across the extension arm, but only limited in Depth direction extends.

It should be noted that the claims clearly and concisely rewrite the claimed invention. The explanations given in the general part of the specification are more extensive and detailed in order to facilitate and support the understanding of the claims. If there is no sentence and word identity between the support of the claims and the claims themselves, this is not to be construed as making the description contradictory to the claims and to supplement the claims with the content of the description of the general part, but the claims are to be interpreted first out of themselves, and for supporting explanation, the corresponding passage of the description can be used. Contradictions are not connected with it, only the legal requirement of the scarcity of the claims as well as the support by the description are fulfilled. It applies the "primacy of the claims", also for the requested protection.

The following examples of the claimed invention are throughout examples of the claimed invention, even though the term "for example" or "especially" does not appear on each page and in each sentence.

FIG. 11

is an oblique view from above, with which the guide groove 41 and the engagement of the downwardly projecting projection 39 is illustrated. The guide groove 41 is arranged along the control section 40.

FIG. 12

is another section with a line of sight from above on the pin 39, wherein the right end portion of the guide track 41 with its bottom-side openings, as in FIG. 10 can be seen, is shown. Also, a spring 14 and an overarching securing portion 15 are in FIG. 12 recognizable, which act on a collar of the end portion 35b of the control arm 35.

FIG. 1 shows a carriage in an oblique view from an inward looking direction. To see are the housing portion 10, to the right of an end portion on which an at least partially plate-shaped spring element is slidably mounted. The arm area with the main arm 30 as a stay arm and the control arm 35 are also visible, as a control section 40. It can be seen bearings 12, 11, in each of which a shaft of a respective roller for the housing portion is mounted. The geometric axis is 20a for the bearing 12 and the associated roller 20 is in FIG. 8 seen. The roller 21 is spaced on the housing portion 10, and arranged on the other side of the main bearing 16 for the extension arm 30. This bearing 11 rotatably supports a shaft 21 'whose geometric axis 21 a and which roller 21 in FIG. 8 shown from below.

The housing portion 10 is above, closed above the rollers, so that they are covered from above and protected against incidental dirt. The rollers themselves have a large diameter, the FIG. 9 can be seen in a weg broken area in the roller 21. The roller occupies almost the entire height H10 of the housing section, reduced by the top covering wall 10a of the housing section.

The rollers have a size of at least 90% of the height of the housing area. The overall height of the housing area is H ₁₀ in FIG. 9 seen. With the housing 10, the rollers, the described arms and the control area a carriage is designed, which can move wings along. The wing can be moved via a tilted position into a parallel position, for which control arms not described here are arranged at the upper edge of the wing and are also displaceable. The wing can also be parked only in parallel, without an intermediate tilt position. In the parallel storage position, the wing is moved over the carriage.

There may be provided two carriages which are spaced and slidably carry the wing at the lower edge. The wing is pivoted to the Abstellarm 30, for which the local recording serves as a bearing 100 with its geometric axis 100a. An arranged on the wing bolt engages in this recess as a bearing and couples the wing to the stay arm 30th

The spaced carriages can both be designed the same, but can also be designed differently so far, as only one carriage uses a control section, and the other carriage has no such control section 40.

The two spaced trolleys with their two rollers after FIG. 8 are otherwise the same education. They are coupled via a coupling rod Ks (or 19), which is inserted into a receptacle 19 ', such as FIG. 8 clarified. This coupling rod is attached to each carriage via a mounting screw 19b in a bore 19a. The bore has a geometric axis 19a 'which is perpendicular to the extension direction of the coupling rod, not shown in the figures. The coupling rod is preferably round and matched in their distance to the horizontal wing dimension so that the two carriages can support the wing and in the position S of the carriages are below the lower edge of the wing, but can protrude from it in the horizontal direction.

The dimension below the wing is small, preferably less than 40 mm, in particular in the range of substantially 35 mm. The sash weight defines the necessary carrying capacity which the extension arm 30, or in the case of two carriages, can receive the extension arms 30 and can transfer to the housing 10. When wings become thicker due to heat insulation requirements, they become heavier. If wings are getting higher due to optical conditions, they are also heavier. For thicker wings larger Ausstellweiten necessary so that the extension arm 30 is to be formed accordingly, while ensuring the inclusion of ever-increasing load capacity due to the geometric dimensions (height, thickness) of modern wings.

The rollers 20, 21 after FIG. 8 , which are rotatably supported by their shafts 21 ', 20' in the lateral walls of the housing 10, support the carriage and run on a track, which is provided by a profiled carriage rail 70 mounted on the bottom of the frame.

Such a track 75 is in FIGS. 4a, 5a seen. The carriage rail 70 is mounted in the region of the lower frame free frame on the frame. The dimension between the lower end of a wing flap, not shown, and the underside of the frame has the size of less than 40 mm described above. Despite this greatly reduced clearance, the rollers are designed in diameter large. The carriage with its housing portion 10 fits in this clearance, drivingly slidable on the track 75, and yet an upper cover of the rollers can be achieved through the top wall 10a of the housing.

Also not shown and used for overall operation is a handle control via a handle which controls the scissors held in slides above. These scissors can be forcibly controlled via the handle, or the handle itself serves to move the wing in a direction perpendicular to the plane of the frame. The handle can also serve to move the wing in the parallel-parked position in the longitudinal direction, mobile supported on the rollers on the carriage rail 70 with the raceway 75 (also called running track).

The position S (closed position) to FIG. 1 is after pivoting the stay arm 30 as a position O (open position) in FIG. 2 seen. The guide pin 39, which has an upper projection 39a and a lower projection 39b, has arrived at the opposite end (right) of the web guide (as a guide groove) 41 and is releasably engaged therein in an angled track portion 41b, to which the lower projection 39b serves as a preferred bolt , This bolt 39b is capable of S of FIG. 1 located at the left end of the guide groove 41 of the control section 40.

This web guide becomes clearer on the basis of FIG. 3 which of the FIG. 1 corresponds and the web guide of the control section 40 explained in more detail. The control portion 40 has a groove 41 made up of a straight portion 41a and a leftward extending latch portion 41b thereof. This latching section defines the position O of FIG. 2 , The end of the straight track section 41 a defines the position S after FIG. 1 and 3 ,

The control link 35 is how FIG. 2 or FIG. 8 make, angled or bent, so is not completely straight. It has a longer straight portion and an angled end portion thereof which carries the double projection 39 extending up and down in both directions. The latter projection 39 is arranged at the front end portion so that a circumferential collar in the thickness of the plate material of the control arm 35 is formed, which runs on the control portion 40 and the top, while the downwardly projecting projection 39 b in the web 41 b, 41 a to be led.

The link 35 is pivotally mounted at its other end via an axis 37 in a bearing of the stay arm 30. The bearing opening 38 and the axis 37 have the geometric axis 37a.

The mounting of the control arm 35 via the bearing 37/38 on the extension arm 30, and the pivotal mounting of the Ausstellarms 30 via the bearing 36/16 with the geometric axis 36a on the housing portion 10 allows the pivoting and the control of the pivoting, controlled by the control section 40th

The straight portion of the control link 35 is 35a, the portion bent or angled therebetween is 35b.

The two positions O and S are from a different perspective, with the view from the outside on the outer flat side 30 'of the extension arm 30 in the Figures 6a and 6b shown. In FIG. 6a is the angled end of the Ausstellarms 30 to see, which is not visible in the position O from the outside. The arm looks straightforward and elongated. The control link 35 is, however, angled, wherein the angled portion carries the guide pin 39, the upper projection 39a in FIG. 6b cooperates with a control block 50 having a top wall defining a closed surface 55 which faces up. The control block is mounted to the carriage rail at one end of the travel path of the carriage. It cooperates with the upwardly projecting projection 39 a, as will be explained in more detail below. Co-operation also finds from the collar of the curved portion 35b and a protruding nose 15 after Figure 2a, 2b in the locked position of the downwardly projecting projection 39b in the angled portion 41b of the guide groove 41 instead. This interaction will also be explained below.

Out FIG. 6a which the other line of sight of the FIG. 3 is, it can be seen that the extension arm 30 from the visible side (from the outside) on the arm surface 30 'the control arm 35 completely hidden. The control arm 35, as in FIG. 8 it is not arranged above an upper side 30 "and not below an underside of the extension arm 30, rather its pivoting plane is designed so that it comes to rest between these two sides (upper side, lower side), ie the front side 30 '(view from FIG outside) reaches the cover of the control arm 35. For this purpose, the plate-shaped handlebar 35 is narrow in the height direction relative to the volume formed Ausstellarm 30. The volume design is also preferably suitable for that they can accommodate a gap or slot 31, as shown in the view of the FIG. 2 on the inner areas between the arm and housing portion 10 is visible. This slot / gap 31 is provided for receiving the control arm 35 in the position S and also designed accordingly. Also, this slot 31 is located in the pivoting plane of the control arm 35, which is not shown separately, but by planar extension in the horizontal direction of the plate-shaped control arm is easy to imagine.

Even if the control arm 35 is bulged slightly reinforced in a middle region, it remains flat plate-shaped. The stiffening bulge 35 c is received by the control arm 35 of the slot / gap 31. From the gap itself protrudes in the closed position of FIG. 3 a little way out the curved portion 35b, and the longitudinal portion 35a of the control link 35 is almost completely received in the gap / slot 31 in the closed position S.

The slit / gap 31 extends in the longitudinal direction of the extension arm and does not extend through the volume of training of Ausstellarms 30, but on the visible side 30 'as large a residual area of material remained to maintain the rigidity of the Ausstellarms 30. At a plurality of cutting planes in the longitudinal direction (cut transversely to the longitudinal direction) is thereby obtained a U-shaped profile of the stay, with a relatively thick connecting leg and two webs, one of which FIG. 2 stronger and the other narrower. The gap or slot is therefore not in the middle between the top and bottom of the stay, but slightly offset upwards.

The slot or gap 31 can thus at least partially record the control link 35 in the closed position, and let him swing out for the position O. At least in sections, the control handle is in the position S recorded, wherein the "straight" section is almost completely absorbed, and the curved portion 35b to enable the guide the control section 40 also protrudes in the position S from the extension arm 30.

"At least in sections" could also be understood that it is no more than sections, in order to obtain the control functions by the double projection 39, in particular as a double pin, in the guide groove 41 of the control section 40.

From the general structure of the embodiment with respect to the arm geometries, it should be said that there is a straight portion 35a and a curved portion 35b (often referred to herein as a curved portion). The extension arm, which is made thicker in terms of volume, relative to the control arm 35, is formed substantially rectilinearly stretched, at least in the region of the housing 10 in the position O after FIG. 2 protrudes. The geometry of the arms is also in FIG. 8 seen in the view from below. The remaining piece 34 after FIG. 6a , which is visible in the position S from the outside, is bent, but is capable of O after FIG. 6b barely visible from the visible side (from the outside). Despite this bent portion at the bearing 36/16, ie at the bearing end of the stay arm 30, this is to be named as elongated straight. Its volumetric training has already been explained in connection with the gap / slot 31.

The coordination of these geometries makes it possible to have a slim, compact design, at the same time to allow controls, and to appear almost completely compact in the closed position, as the very clear in the FIG. 6a comes to light.

The control, which has already been mentioned, takes place via a double projection 39, which has an upwardly projecting projection 39a and a downwardly projecting projection 39b. These two are preferably designed as a bolt, more preferably provided with a rotatable sleeve in order to be easier to guide and to produce less friction in the guide. The double projection, which from all views of Figures 2 , of the FIG. 6b and the detail enlargements of the FIGS. 11 and 12 can be seen, has two different functions or tasks above and below, with essentially the same design. Arranged is the double projection in the bent (curved) end portion 35b of the control arm 35. It leaves a covenant around it as a plate-shaped collar stand, so does not quite extend to the outer edge of the control arm 35 in the region 35b zoom.

The downwardly projecting projection 39b is provided for downward feeding. The triggering from the locked position after FIG. 2 is the task and function of the upwardly projecting projection 39b. The locked position is that for the parallel adjustment of the wing. The triggering takes place from above. The triggering takes place as it is in FIG. 6b is achieved by running the upwardly projecting projection 39b in a lateral recess 51 of the control block 50. This control block 50 is in FIGS. 7a, 7b explained from two oblique views. Here, the shrinkage of the upwardly projecting projection 39a in the direction of V _{39 is} shown, in the one Schrägaufnahme 51, of which the control block 50 may have two in order to be used for left-hinged and right-hinged applications can.

The control block 50 is mounted on the carriage rail 70. The carriage with the housing 10 runs in FIG. 6b - When opening the arm 30 - from left to right, and he engages at the end of the travel with the leading (forward projecting) control section 40 in a transverse through further recess 53 of the control block 50.

This further recess allows the intervention in direction V ₄₀ after Figure 7a , which may be more than just an intervention, in particular a Durchgreif, which by the freeing of the front end of the control section 40 in FIG. 6b is apparent.

In a temporal end region of this engagement, in particular the punch-through by the receptacle 53, which is provided transversely in the control block 50, is the time at which the web-like entrance 51 acts on the upwardly projecting projection 39a.

The control by the inclined path 51 at also obliquely placed groove portion 41 b of the guide groove 41 leads to a retrieval of the control arm 35, respectively of the downwardly projecting projection 39 b from the angled groove portion 41 b and leaving the position O, as in FIG. 6b shown.

The cart moves back in FIG. 6b to the bottom left, and the extension arm 30 is pivoted in until it moves to the position FIG. 6a reached. There, the housing 10 is clearly spaced from the control block 50, while it has arrived at the beginning of the acting from above picking out of the locked position on this control block 50; in the last position, the control section 40 passes through the control block 50.

For the passing through, it is helpful that the control section 40 is designed to lead forward. He is designed nose-shaped slim, the control section 40 is nevertheless stiffened, which is based on the FIGS. 10 to 12 is explained in more detail.

The guide groove 41 with its two sections 41a, 41b is provided in the nose-shaped slender control section 40. The angled portion 41 b is in a bulging bulging side region 42 (belly) to FIG. 10 placed, which in turn engages in a bay-shaped recess 33 in the position S of the stay arm 30. This interposition of "belly" 42 in bay 33, as in FIG. 2 it can be seen that is the one FIG. 6a ,

This makes it possible to achieve the position O for the parallel shutdown by the angled portion 41 b, and yet to make the extension arm 30 close to the housing 30, and thereby assume a nearly parallel position to the carriage rail 70, this in the situation S.

It can be seen that the bay-shaped recess 33 is disposed below the slot / gap 31, and as little material as possible from the volume trained Ausstellarm 30 should take out to maintain its rigidity, but at the same time the closed position position S as close as possible to the housing portion 10 and the carriage rail 70 to allow. It is obvious FIG. 2 also that this bay-shaped recess 33 does not reach right up to the underside of the extension arm in the height direction, but the extension arm 30 is closed surface-wise on three sides.

The guide groove 41 is not completely closed down, but has a not more than partially closed formed bottom structure. In other words, the soil is present in sections, resulting from the FIGS. 10 and 12 and FIG. 8 becomes apparent.

In FIG. 10 is seen from above into the groove 41 whose web shape; the section 41a is the rectilinear section and the angled section 41b extends downward at an angle of slightly less than 90 °. It thus forms a pocket-shaped recess for the latched position S of the downwardly facing projection 39b.

After the bottom of the groove 41 through the openings 41 ', 41 "and 41 * is broken, with the leaching of the example in the FIG. 10 two floor segments 44a, 44b, the rigidity of the forwardly projecting control section 40 is increased. In several sectional planes, perpendicular to the longitudinal extent, a U-shaped profile is provided, which ensures the rigidity of the nose-shaped slim control section 40.

Through the bottom opening (s) through dirt particles and other contaminants can fall through, which could affect the path control. For longer periods of operation, it can not be ruled out that even with a concept largely covered from above FIG. 6a get disturbing contaminants in the web 41. Upon movement of the downwardly projecting projection 39b, these dirt particles are removed as far as they deposit on the floor segments 44a, 44b used for stiffening. The downwardly projecting projection 39b has a clearing action in connection with the bottom openings 41 ', 41 "and 41 *.

In the Figures 2 and 6b represented position O, as well as in FIG. 8 is not only secured by the angled portion 41 b, but held reliably by two other measures.

At the moment, in FIG. 6b is clear, projection 39a is reliably taken over by the control block 50 and its track-like entrance 51. The further measure is structured as follows and designed functionally.

An overarching section 15, as in FIGS. 2a, 2b can be seen in the enlargements, engages over the collar 35b ', which surrounds the double projection 39, and a part of the bent portion 35b of the control arm 35 is. This attack by the nose-shaped projection 15 ensures a vertical moving out or jumping out of the projection 39b from the guide groove 41 and a vertical displacement of the control link 35th

This spreading is given not only in the locked position of the position O, but also when retracting to FIG. 6b , And the transfer of the holding function of the angled portion 41 b to the web-shaped entrance 51 in the inward movement V _{39 of} the downwardly projecting projection ₃₉ b. At this time, the collar portion of the bent portion 35b of the control arm 35 moves further under the nose-shaped projection 15, loads an underlying spring member 14 which allows this movement, and enters the engagement portion 51 of the track of the control block 50 where it is securely held this engaging portion is closed at the top, as a result of the upwardly closed wall 55 of the control block 50. Falling out, a vertical moving out or jumping out is reliably prevented.

The mentioned spring as a spring element 14 is clearer in FIG. 2b in the supervision and in FIG. 2a to see. It has a bow portion, which is visible in sections next to the nose 15, but is located substantially portion below the nose-shaped cross-section 15.

The spring element 14 is continued in a holding portion 14b, 14c, which is U-shaped and through the above-open window of the holding chamber 13 in FIG. 2b is apparent. The spring is inserted from below into an opening, and engages with its free end 14c behind a projection in the holding chamber 13 a. It is thereby fixed in position, but can be replaced at the same time, when with a tool, the free end 14c is bent away from the projection, and the spring element 14 is taken down. A new, identical spring element 14 can then be inserted and fixed from below.

The securing position in the locked position according to FIG. 2 or FIG. 8 , or the FIGS. 11 and 12 is additionally secured by the spring element 14. This exerts a compressive force on the lateral plate projection 35b 'as a covenant of the raised portion of the control arm 35, and presses him reliably in the latched position at the end of the angled portion 41 b of the guide 41nd

A portion of the arcuately shaped spring back of the retaining spring 14 is disposed below the nose 15, and above an upper surface of the control section 40th

The pivoting of a carriage in the carriage rail is based on the FIGS. 4a to 5b be explained. The end portion of the carriage shown here is the one in the Figures 1 and 2 is located on the right. It is an end portion, into which the connecting rod 19 is inserted, which is fastened via a - not shown - threaded hole 19a with a mounting screw. Above this attachment portion 19 'for the connecting rod, a spring piece 60 is provided, which has two locking positions, which are described below.

The spring 60 is also in FIG. 1 to see and there has the location, which in FIG. 4a in the oblique view and in FIG. 4b can be seen in the front view. It is a latched position which is achieved by a first groove 18a disposed on top of the carriage end (the carriage's housing).

A second groove is designated to the left of it with 18b and has a distance. There are thus two spaced groove sections, as on the FIG. 4a seen.

The spring piece 60 is arranged on top and has a shape of several sections. A resilient portion 62 has a U- or V-shape and a grasping portion 63 at the end. This one is in FIG. 5b most clearly seen, engaged in the second detent position in the groove portion 18b.

The spring piece 60 further has a projecting planar portion 61, which is achieved in the example shown by a bend 61 a with feedback with additional stiffening waveforms 61 b. This "front portion" may also be a simple plate-shaped piece of a sufficiently stable material, which is provided at the right end with a spring portion which corresponds to that portion 62, 63 which in FIG. 4a is freely visible.

The effect of this spring piece 60 is first that it is displaceable.

It is placed in the first detent position in the groove portions 18 a and the front portion 61 of this spring protrudes barely and not enough in the example shown to an overarching portion 71 of the carriage rail 70. In this detent position of the spring piece 60 of the carriage in the carriage profile of carriage rail Swung 70 and swung out of it. In other words, the carriage can be used when the carriage is tilted, the rollers are placed on the web 75, and placed in profile by inward pivotal movement of the carriages. This position is in the FIGS. 4a, 4b shown. Likewise, the removal of the carriage can be made by pivoting back in the opposite direction. This too, or only if the spring piece in the in FIG. 4b placed position, and the latching of the spring piece with latching portion 62 has taken place in the grooves 18 a.

The spring piece 60 is moved in the direction F ₆₀ , as in FIG. 5a is shown. It then reaches the second detent position in the grooves 18b. Here, the section 61 protrudes far and blocks a gap 71 a, which was previously free. This free gap is needed for swinging in and swinging out the carriage. If the carriage pivoted in and used, the gap 71 a disturbs the reliable movement and could cause the carriage jumps out of its path 75. This can be prevented by the pushing of the spring piece 60 in the horizontal direction when the spring occupies the second detent position in the grooves 18b, and the front portion 61 reduces the gap opening.

When forces are applied in the direction of pivoting or jumping out of the carriage, the plate-like front portion 61 of the spring piece 60 can prevent the carriage from disengaging from the carriage rail.

It can be seen that the spring piece 60 designed as a whole out of spring plate FIGS. 4a to 5b may also have only one spring portion in the region 62, and the front (plate-like) portion 61 - in a manner not shown - plate-shaped or may be formed as a plate, the plate thickness is suitable to choose the gap 71 a in its height to reduce.

So the plate shape will not take more than one section. The at least one, preferably two pairs of grooves 18a, 18b serve the detent position (s) of the spring piece, and rewrite its position in a position permitting swiveling FIG. 4b , and a position preventing the falling out or swinging out after FIG. 5b ,

The mutatis mutandis plate-shaped portion 61 of the spring piece secures in the gap 71 a. The gap 71a is thereby substantially reduced. The extent of the reductions is an almost complete closing of the gap, such as FIG. 5b shows.

It should be noted that one of the locking positions 18a, 18b may also be omitted or may be a held by friction or clamping position of the spring piece. This latching position is preferably that of the groove pair 18a. Here, the spring can only be placed without being locked separately on the edge in a recess, cf. FIG. 5a , Only the pushing in F _{60 of} the spring piece 60 and the locking in the groove pair 18 b is useful for the reliability of the blocking of the gap 71 a.

To the heights of carriage and Ausstellarm should the FIG. 9 be explained in more detail. The extension arm can be seen here from the visible side from the outside. He has a height H ₃₀ . This height brings the Ausstellarm 30 high rigidity and load capacity. The height H ₃₀ is almost the height H ₁₀ , which relates to the housing portion 10 of the carriage. The height H ₃₀ is greater than at least 80%, preferably greater than 90% of the height H ₁₀ .

Also visible is the size of the diameter of the roller 21, which also has almost the size H ₁₀ , while above 90% to above 95% of the height H ₁₀

Compared to the control arm 35, the height H ₃₀ of the extension arm 30 is substantially thicker and thereby measured at least four times as strong in the height direction. The height extent of the control arm 35 is still to be regarded as a plate-shaped even with stiffening expression 35c.

Also visible FIG. 9 is that above the top and bottom of the Ausstellarms 30 no control arm is visible or arranged, and that the overall height of the Ausstellarms 30 can contribute to the overall load capacity and rigidity of this arm, especially if the provided gap 31 in a Example does not extend completely through the transverse direction of the extension arm 30, and also extends only slightly in the longitudinal direction, and thus does not bring about a reduction in the load capacity and the rigidity of the Ausstellarms 30.

The jumping out of the carriage from the geometry of the rail 70 as a carriage rail is prevented by a projection 17 in FIG. 1, 2 and in the front views of the Figures 4b, 5b is apparent. This attaches to the housing 10, and may be considered part of the housing.

The gap 71 a is dimensioned below the projecting portion 71 of the carriage rail 70 so that this projection 17 can be pivoted in below 71, and then justified the protection against jumping out when the gap is reduced. The projection 17 would be at the emergence of the carriage on a Obstacle against the downwardly projecting projection 71 abut, and with inserted spring piece 60 takes over this striking the plate-shaped portion 61, which lies on the projection 17. The section 61 is for this purpose made of said, sufficiently stable material.

The longitudinal extension of the projection 17 may, as FIG. 2 shows to be limited. Preferably, the spring piece 60 projects with its plate-like portion at both ends of the projection 17 beyond this in the longitudinal direction. The projection 17 supports the plate-like configuration 61 of the spring piece 60 resting thereon, in order to prevent the spring piece 60 from being pushed out by operational movement.

The effective plate-shaped portion 61 may protrude inwardly over the front end of the projection, as in FIG. 5b is shown. The spring piece shown there with its plate-like portion 61 (by a U-shaped bend of a spring plate with stiffeners), protrudes front side (seen to the left) on the securing projection 17 also.
