Abstract

The invention relates to a fitting for a slide-and-tilt or sliding sash which can be displaced in parallel. The operator-friendly fitting comprises two lower carriages (4a, 4b) which can be displaced on a running rail and are coupled to one another at a distance by a connecting rod. The fitting has at least one upper sliding element (5a, 5b) that can be displaced in a guide rail and is provided with a second connecting rod. A swivelable extension arm (10a, 10b, 20a, 20b) is associated with each of the two carriages and the at least one upper sliding element. An energy accumulator unit (E, 15, 25) is coupled to one of the extension arms of the carriages or to the extension arm of the upper sliding element. When all extension arms execute a swiveling storing movement, the energy accumulator unit absorbs energy from a closing position during the storing movement of the extension arms. After the latching of at least one of the extension arms of the carriages or the latching of the extension arm of the upper sliding element in the swiveled-out position, this energy is stored.

Description

User-friendly fitting

for parallel sliding wings

The invention relates to a fitting for a sliding sash or a Schiebekippflügel as wings. This sliding leaf can be moved parallel. The sliding squeegee is also tiltable. The sliding (tilt) wing has a parked position (in the Parallelabstellung), in which it is displaceable, for opening and closing. He has a closed position in which he retracted in the frame and pressed against the seal. Between the closed position and the Parallelabstellung is a transition during which swing out or pivot the Ausstellarme, depending on the direction of movement, ie swing to open and swing to reach the closed position of the parallel shutdown of the wing.

After the fitting is claimed, the positions refer to the positions of the Ausstellarme, ie their closed position and their pivoted position and the transition as "the

Abstellbewegung. "These positions of the arms can be transferred with a mounted fitting on the sliding sash.

Fittings for parallel-shutters are known, e.g. from EP 619 410 A1 (from HAUTAU) or from EP 1 959 080 A2 (from HAUTAU). These fittings have for the sliding wing two lower, mounted on a mountable on the wing frame running rail, held by a connecting rod at a fixed distance trolleys and two upper, slidable in an attachable to the frame slide rail, held by a connecting rod at a fixed distance sliding elements. The carriages and the sliding elements are connected to the wing in each case via a Ausstellschere with Ausstellarm. To operate, the fitting on one side, the front of the wing, an operating handle, which is coupled via connecting rods and deflecting parts at the wing corners to the front carriage and the front sliding element.

From EP 201 717 (by GU) a removable sliding sash is known, which can be moved in parallel. It is held on lower Ausstellarmen and moves in its deployment movement along a path which has a buffer element (there 28) at the end, with which the wing is braked. The buffer element is preferably made of Vulkollan and the inherent elasticity of the material is added to the springing property of the spring used there damping, i. the buffer element already absorbs a large part of the kinetic energy (see page 10, first paragraph at the end). The buffer is there as both for left usage and

Right application described applicable and he (there page 11) can be mounted basically at any point of the track, but is preferably so attached that the sliding wing completely or at least largely in

Sliding opening position can be brought.

From DE 297 04 103 (also by GU), a spring element is also known, which is used in a door closure. The door has a rotary wing and in the opening movement of the door (there Figures 3 and 4) a kinetic energy is stored in the local spring element, which leads to a dampening back pivoting movement when pivoting back the door, see. there page 25, third paragraph. The extent of the resulting damping of the return movement can be varied by an axial displacement of a valve rod arranged in the interior of the hollow piston rod.

Finally, from DE 20 2004 008 320 U (also by GU) a tilting wing is known, which is called a building tilting window and is provided with a buffer spring in the local scissors, the sprung for braking the tilting movement of the window sash (before reaching one of maximum open or tilt position corresponding state of the tilting fitting) is elastically deformed, see. there claim 1, page 6, left column.

The fittings of EP '410 AI and EP Ό80 A2 work reliably in the mounted state. However, there are difficulties for the person opening or closing the wing, as it may be difficult for them, the wing during the movement in the sealing

Press firmly closed position accordingly and to hold in the position of movement in its position parallel to the frame safely.

It is an object of the invention to facilitate the closing operation of the wing and to make user-friendly.

This object is achieved by the teaching of claim 1 or 20 and in which

Subsequent dependent claims further developed, at least advantageous.

The pivoting of the wing from its sealed closed position is relatively easy. As soon as the wing is unlocked, it is slightly pushed off its sealing position by the sealing elements pressed together in the sealing position from the frame. The further shutdown of the wing is relatively light. From the movement that initiates and determines this movement, the storage unit coupled with a tilting arm absorbs energy (claim 1, 20).

During the entire displacement movement of the wing in its open position, the

Storage unit store this energy (claim 2). It can release the stored energy only when the wing is pushed back completely and its pivoting movement begins in the pressed closed position (claim 3). Releasing the stored energy facilitates the pivoting movement. It also supports a maintenance of a parallelism of the wing to the frame when the top and bottom of such energy storage is provided (claim 9). The release takes place with the unlatching of preferably only an upper arm or scissors (claim 7, 18).

The energy store can be designed so strong that it takes over the pressing movement itself after the latched position of the arms has been solved. Helpful here is a bias in the energy storage, which also provides power available when the wing is included in the frame and has reached its (pressed) closing position.

Overcoming this basic force when opening a user - as a relative

carefree - to be expected.

The design of the fitting, which is more user-friendly, can be implemented in many variants of the two functions "energy storage unit" and "latching" which can be assigned. A latch can be assigned to an upper arm or a lower arm, or both arms. An energy storage unit can also be assigned to an upper, a lower or both an upper and a lower one. It is possible, the

Lock the one upper arm and couple the energy storage unit to the other upper arm. In the same way, this also applies to the carriage side. Here the latch can be assigned to one arm of the first carriage, and the energy storage unit can be coupled to the other extension arm of the other carriage.

Objectively, the locking and the coupling with the energy storage via a respective auxiliary link is executed (claim 18, 19). The auxiliary link for the locking is shorter, the auxiliary link for the coupling with the energy storage is longer (claim 19). The auxiliary link for the coupling with the energy storage unit can be designed as a trailing arm (claim 4).

If two functional catches, one assigned to the upper Ausstellarm and the lower Ausstellarm, so they are designed to lock and at the same time to unlatch (claim 12). This results in a high synchrony of the beginning of the

Influence of supporting closing force after unlocking.

If only one extension arm is provided at the top (a single arm or a pair of scissors consisting of several coupled arms), both functions are assigned to this extension arm (scissors), provided that both functions are provided for the upper fitting part. The (only) one extension arm (claim 7) is then pivotally coupled to a first auxiliary link for the latching and a second (longer) auxiliary link for the influence of the energy storage unit (claim 4). Both links can be arranged at the same hinge point.

The energy storage unit, preferably in the form of a long-stretched spring brings in the Einschwenkbewegung compressive force on the (longer) auxiliary link and moves the (only) a deployment arm in the direction of its closed position, but only if the locking of the second (shorter) Assist steering is solved.

If one of the functions for the upper fitting part is missing, the corresponding one also falls

Auxiliary steering continues.

In a preferred embodiment, the energy storage unit is designed as a cylindrical spring (claim 17), which is covered. For this purpose, a sleeve is used, which is pushed over the entire spring length. The sleeve is held on two end pieces, which also bears the cylinder spring. The sleeve can preferably be pushed over the cylinder spring, which can be threaded on a round rod.

If one considers the upper fitting part with the at least one sliding element as a system, then the system boundary can be placed after the energy storage unit, with which perspective a functional section of the upper fitting part is produced at least one extension arm, at least the longer auxiliary link and the energy storage unit has, if they are provided for the upper fitting part. After the system boundary, a (second) slider can be provided again. Such an arrangement is preferably used for those sliding sashes in which the (only) one extension arm is arranged at a position in the longitudinal direction of the sash which lies substantially vertically above the front grip region. As a result, for the upper fitting part no closed parallelogram of at least two arms, the upper wing spar and the connecting rod between the two

Given sliding elements.

The invention is described below with reference to schematic drawings in several

Embodiments described in more detail:

Figure 1 shows schematically and in perspective an example of

Fittings, the frame and the sash.

Figure 2a shows the lower fitting part 4 of the fitting in supervision in

the open position (pivoted Ausstellarme 10a, 10b);

FIG. 2b shows the same fitting part as in FIG. 2a, with a view into FIG

Opening direction.

FIG. 3a,

Figure 3b show in the same representation as Figures 2a and 2b the

Fitting part, but in the closed position (pivoted

Raising arms).

FIG. 4 shows the front carriage 4b in the open position,

but in an enlarged view and with further details

of release of latching with 17 ', 11c of a pivoting position

(Open position).

Figures 5 show the movement of the lower Ausstellteils in

four pictures (FIGS. 5a to 5d). The relation shows the

Guide line F, which runs centrally through the control block 12.

It forms the reference in all figures 5. Figure 6a shows the upper Ausstellteil 5 (fitting) of Beschla

the open position (looking up at the mounted,

swung fitting part on the frame 1).

Figure 6b shows the same fitting part as Figure 5a, but as a section

in a median plane M.

Figure 6c is the front portion of Figure 6a with a lock

(Locking) on the auxiliary arm 30, only in the direction of

above (in Figure 6a from behind). This is the grip side GS.

Figures 7 show three views of Figures 7a, 7b, 7c of a

alternative fitting with (only) one upper

Extension arm 20b '. Again, the handle side (left in the picture)

shown, with the fitting part on the other side

closes. The only one extension arm 20b 'are two

Anchor handle 30 ', 21' assigned. The system limit is

located.

FIG. 8 shows the fitting of FIGS. 7 in the closed position

(Swung arm 20b ').

The figures show the fitting in a preferred embodiment. Only the figure 1 also shows the wing 2 and the associated frame.

Since the positions of the Ausstellscheren (top and bottom) correspond to the positions of the wing relative to the frame, it does not require a representation of the sash and frame in the other figures.

In Figure 1, the parts of the window and the fitting are shown only schematically and separated from each other, since the basic structure and the basic interaction of the frame are well known. The frame 1 and a removable and movable sash 2 are shown. The unillustrated rod on the front vertical wing frame controlling handle 3 is provided for locking and unlocking.

The lower fitting part 4 comprises a front carriage 4b and a rear carriage 4a, each with a stay. Likewise, the upper fitting part 5 comprises a front sliding element 5b and a rear sliding element 5a, which also both with a

Ausstellarm are equipped. The aforementioned extension arms can be components of Ausstellscheren. With a respective extension arm, at least one auxiliary link is preferably pivotally coupled, so that the term scissors also includes this.

According to FIG. 2a, an energy storage unit E, preferably in the form of a compression spring 15, is coupled to the extension arm 10a of the one carriage 4a, preferably, as shown, of the rear carriage.

An auxiliary link 13 is connected via a coupling member IIa in a central region of the

Ausstellarms 10a articulated as Zugarm. Its other end 13 'is slidably disposed on an adjusting element 14 or the like sliding element on a connecting the two carriages 4a and 4b of the lower fitting part 4 element 16 (usually round rod).

In the direction of the associated carriage 4a is on the connecting element 16 a

Abutment for the energy storage unit E in the form of a pressure ring 16 a stationary relative to the rod 16 is arranged.

It can be seen that the adjusting ring 14 and the adjoining or fixed end of the storage unit 15, with respect to the pressure ring 16a upon movement of the Ausstellarmes 10a from the closed position of Ausstellarme according to Figures 3 to the spaced position shown in FIG 2 undergoes compression and thus a Energy increase (or storage) occurs, b ₀ <b ₂ .

This is stored in that the parked position of the opening arms of the fitting is locked, as can be seen from Figure 4.

Figure 4 shows the extension arm 10b, which is arranged on the handle side (or front side) of the fitting, namely the lower fitting part 4. In a special

Embodiment, the arm 10b is held in the issued position by an L-shaped groove 17, 17 'in a leading sword 18 on the carriage 4b. In the figure 4, this groove 17 is visible only in the straight section under a control piece 12, which is the leading

Sword 18 in the position or position of the lower carriage 4b shown in Figure 4 receives. For further explanations of this leading sword 18 on the carriage and the control piece 12 reference is made to the sequence of figures of Figure 5, where this control piece 12 is still separated and spaced from the leading sword 18 can be seen. Of the

Section 17 'forms the angling of the control groove 17 for the described L. The latched position can be seen in Figure 5a, characterized in that the hinge 12b of the auxiliary link IIb of the stay 10b in the transversely directed receiving portion 17 'of the cam 17 of the sword 18 is locked or locked. This lock is releasable when the 'hinge' 11 c is moved out of the transverse portion of the cam 17 and this is done by the control block 12 (as a control piece) having a corresponding receiving groove 12 a for a pin in alignment of the joint 11 c, with the the joint, which is guided on a downwardly projecting pin in the control groove 17, from the

Undercut (the transverse end portion 17 'of the cam 17 in the sword 18) is taken out and is transferred in the straight section 17. This time range of Entrastens shows the figure 4, corresponding to the representation of Figure 5b, in which a roughly the same state as in Figure 4 is reached, only the control block 12 is not partial

shown broken away, so that there the recording - the triggering 12a - is not visible.

For a more detailed description of this type of release of a latched state, reference is made to WO 2010/079461 A2 (by HAUTAU), there the specially shaped control block in FIG. 7 a, the control groove in the transverse direction provided with a latching section 41 b in FIG. 1 in the leading blade 40 and the associated latched state of the parked arm 30 in Figure 2. The timing of entry of the latched arm with the control projection 39a is seen in Figure 6b there, which projection 39a corresponds to the projection 12b as a hinge in this Figure 4.

It is therefore evident from Figure 4, the release of the latched state.

It should be noted that the state of locking can be made by only one of the two lower arms. This may be the other arm on which the

Energy storage unit E is not articulated, so the arm 10b, as Figure 4 and Figure 2a show. The lock can also be arranged in addition to the storage unit E on the same arm 10a. Also, locking is only possible on one of the upper arms 20a, 20b. "Verrastung" is insofar functionally to understand that the parked state is to lock.

This locking in the parked state is achieved for four extension arms, if only one of these extension arms has a latching according to the illustration of Figure 4. If a high symmetry is desired, can be provided at the top and bottom of each lock, which can be realized a little differently due to the different Armausbildung, but functionally works in the same way.

Also for the top of Figure 6c, the leading sword 18a can be seen, which has the groove guide 17a of Figure 6a. The in the undercut, so the Verrastungsabschnitt 17 a 'of Stem 21a with cam 17a is shown in FIG. 6c. He is part of the

Auxiliary handlebar 30 on the extension arm 20b of the upper Ausstellteils. 5

The sequence of entry of the lower fitting part 4 in the closed position shows the sequence of figures of Figures 5a, 5b, 5c and 5d. FIG. 5a has already been mentioned. It shows the latched state of the auxiliary arm IIb, which holds the front main arm 10b as a stay in the undercut 17 'of the cam 17 latched. Thus, the other arm (coupled via the wing, not shown, and the wing pads PI and P2) is held in the latched position. The other arm 10a is biased with the energy storage unit E, which is shown here as a compression spring 15. The energy storage unit 15 has the longitudinal extent b ₀ , which is smaller than the unlatched state b ₂ , which is shown in Figure 3b and 5d (at a distance a = 0). The spring is thus tensioned and energy is stored via the rear arm 10a. The

Locking is met by the front arm 10b.

For the purposes of Figure 5, this task distribution of the two arms should be assumed. It can also be configured differently in the above illustration, or the latching and storage can be assigned to the same display arm.

FIG. 5a corresponds to FIG. 2a. Figure 5a shows a fitting part 4 for a right

2a, such a stop for a right-wing (with the control block 12 shown on the left in the picture).

The storage of the energy is carried out according to FIG. 5a. It is associated with the extension arm 10a. The lower fitting part 4 moves in Figure 5a to the right. 5b it reaches the control block 12. The sword 18 is retracted and a recess in the control block, corresponding to that recess 12a of Figure 4, not visible in Figure 5b, triggers the latched state of the hinge 11c of the auxiliary arm 10b. The locking is symbolized by llc / 12a.

The stored energy by compression of the compression spring 15 with the memory length b ₀ begins to release. b ₀ is larger, and the wing supports PI and P2 (usually metallic profiles) approach the closed state, as Figure 5c explained. The distance ai becomes smaller than a ₀ . At the same time, the carriages 4a, 4b move back a little way. This is illustrated in FIG. 5c on FIG. 5d.

The length of the compressed spring 15 has grown to bi, so that a corresponding potential energy is transferred into a kinetic energy of the vane (not shown in Figure 5c, but representatively represented by the reduced angular position of the Ausstellarme) has been. bi is only slightly larger than b ₀ , since the distance of the carriage 4b from the

Control block 12 is still low, but the release from the latched state, as can be seen on the changed pivot position of the pivot arm 10b, has already taken place (ai <a ₀ ).

According to the extension of the energy storage unit 15 and the distance of the wing support P2, usually a profile, and also the wing support PI, compared to the vertical plane of the connecting rod 16 is reduced. This difference with respect to the previously locked position with the distance a ₀ is also evident, as is the extension bi with respect to b ₀ in the energy storage unit E, shown as a compression spring 15 in Figures 5.

Between the figure 5c and the figure 5d has the complete Einschwenkbewegung

occurred, so that the Ausstellarme 10 b and 10 a are pivoted and have taken a parallel position relative to the connecting rod 16. The distance ai has dropped further and is essentially zero as a ₂ . Correspondingly, the length of the spring is increased to b ₂ while releasing the stored energy.

In the period between Figure 5b, but actually only the figure 5c and Figure 5d, the stored potential energy of the energy storage unit 15 / E has been delivered to move the wing with its weight in the closed position, or the user in the leadership to support the wing in the closed position. That corresponds to one

"Upward movement" from a slightly lowered position (viewed in the vertical direction, due to the blade weight), which has been supported uphill by the released energy of the storage unit E.

As a result, the user needs less power. The released energy between especially the positions of the figures 5c and 5d is released in the back-pivoting movement of the arms. This happens after unlatching, as shown in Figure 5b.

Other sections are also apparent from the figure sequence. It can be seen from FIGS. 5a and 5b that the stored energy is moved along with the lower fitting part 4 in the parallel direction. During the sliding movement, the energy storage unit stores the energy to be released later.

This happens during the sliding movement of the carriage, both towards the full open position, as well as towards the closed position. During this state, at least one of the arms 10a, 10b is locked, or none of these arms locked, when an upper scissors construction is added, which has a latching on at least one of its arms.

Finally, it can be seen in the reverse order from FIG. 5d via FIG. 5c to FIG. 5b how energy is absorbed and stored from a closed position. In this case, the energy storage unit from the closed position with the extension b _{2 is} compressed when the Abstellarme 10 a, 10 b swing out. This is done via the arm 13, which is pulled by the stay arm 10a in Figure 5c to the left, and thus the energy storage unit E charges, respectively, the spring 15 is compressed. The continuous compression by further swinging out of the arms 10a, 10b ends in the state of locking according to Figure 5b, in which state the potential energy then achieved is "latched" by compressing the spring length to the length b ₀ .

All individual sections of the overall movement can be seen from the figure sequence of Figures 5.

In the figures 6a to 6c, the upper fitting part 5 can be seen.

There, a short arm 30 is articulated on the extension arm 20b of the front sliding element 5b, the other end engages with a pin on the joint 30a in a guide groove 17a and in this at the end of the Ausstellbewegung the Ausstellschere in a lateral (transversely directed) locking portion 17a 'of the groove 17a engages in which he - recognizable in Figures 6a and 6c - is.

In the upper fitting part, the connecting rod 26 between the two

Sliding elements 5b and 5a housed in the guide rail 27. At the end of the extension arms 20a, 20b, a connecting rod 28 is articulated, which is arranged on the front side of the wing.

The tension member 21 acts as an auxiliary arm on the slide ring 24. The spring 25 is supported on the fixed abutment 24a. A pulling takes place during the Einschwenkbewegung of

Ausstellarms 20a, caused by the spring element 25 as energy storage.

The distance between the fixed abutment and the sliding ring and thus the tension of the compression spring can be matched to each other at the top and bottom.

It was previously mentioned that functionally the storage via an auxiliary arm 13 at the lower fitting part is the same as storage via the auxiliary arm 21 at the upper fitting part 5. Structurally a little different is formed by the arms and connecting rods parallelogram of the upper fitting part 5, as Figure 6a illustrates.

The ends of the Ausstellarme 20a, 20b are pivotally connected to each other via the connecting rod 28 and the distance of the sliding elements 5a, 5b creating connecting rod 26 is plate-shaped.

In this connecting rod 26, an elongated central slot is disposed closer to the slider 5a, in which the spring unit 25 is placed. For this purpose, an intermediate rod 26a is attached between two points 24a, 24b. On this intermediate rod, which can be designed around, in the example designed as a cylindrical spring spring element 25 is threaded. It is compressed on this intermediate rod 26 a, when the pivot point as a sliding ring 24 moves along this intermediate rod 26 a, to shorten the distance between the

Points 24,24a.

Although a cylinder spring of mechanical nature is shown in Figs. 6, other types of springs capable of absorbing compressive force are also suitable. Possibilities are

Gas springs, sheathed mechanical springs, accumulator springs, and other spring-like elongated members capable of applying a compressive force after having previously been longitudinally compressed or charged.

The detail enlargement of Figure 6c shows the left portion of Figure 6a, viewed from the back. In this case, the locked state is shown at the hinge point 30a of the auxiliary link 30, as he engages in the undercut 17a 'of the guide groove 17a.

A further embodiment, the three figures 7a, 7b and 7c in the open position and the figure 8 in the closed position. The open position corresponds, as in the other examples, the swung-out arms, here the only one swung-out arm 20b 'of the upper fitting part. In Figure 8, this single extension arm 20b 'is pivoted.

The associated lower fitting part 4 can be seen from Figures 2a, 2b, in a corresponding inversion for the same stop side (in Figures 7 as a left-hinged fitting, in Figures 2a, 2b as a right-fitting fitting).

The upper fitting part is an alternative to the other example of Figures 6a, 6b. From the description of the corresponding reference numerals of the elements used here are taken. Functionally equal is the one extension arm 20b 'the extension arm 20b from Figure 6a (in consideration of the changed direction of attack, right or left hinged fitting).

The auxiliary link 21 ', which was articulated in Figure 6a with the other extension arm 20a is coupled in the embodiment of Figures 7 with the one (single) extension arm 20b'. The coupling point is a joint 22 to which the other auxiliary link 30 is articulated. He is the (shorter) handlebar, which is responsible for the locking, which works as well as in Figure 6a with the functional elements 17b 'and 30a. A more detailed explanation can be found for the time of the beginning of the release of the locking position in Figure 4, with reference to the

Carriage side.

In the swung-out and latched position shown in FIG. 7a, the energy storage unit used in the example as cylinder spring 25 stores potential energy. It is threaded on a rod 26a, on the right side at an abutment 24a

is held immovably relative to the connecting rod 26. On the left in Figures 7 side, the spring is coupled to a collar 24 which is movable in the longitudinal direction. It is used in the example in the longitudinal slot of the connecting rod 26 and connected to the one end of the long auxiliary link 21 'articulated.

In the illustration shown, the spring 25 is guided on the round rod 26a and has left and right each have an end piece, between which the cylinder spring is inserted. The end piece 23b is designed to fit the adjusting ring 24. The end piece 23a is supported on the anvil 24a. If the adjusting ring 24 moves to the left in FIG. 7b, the spring 25 releases its stored potential energy, with the left-hand end piece 23b moving together with the adjusting ring 24 to the left, as shown in the closed position of FIG.

The auxiliary link 21 'applies a force to the bearing 22 on the extension arm 20b' when the other (shorter) auxiliary link 30 has left the latched position with the Verrastungsvorsprung 30a, respectively latter Verrastungsvorsprung triggers from an undercut provided along the guide track 21a is. Then the handlebar pivots 21 ', emerging over a

Torque between the two joints 22 and the joint 22 "of the arm 20 b 'on the upper sliding member 5 b' the extension arm 20 b 'in the closed position, respectively the

pivoted state, which corresponds to the closed position of a mounted wing.

The spring 25 can be covered by a sleeve, not shown, which also extends over the two end pieces 23b, 23a, so that the spring is always completely covered, however, the end piece 23b together with the adjusting ring 24, the lifting movement between the extended position of Figure 7c and the closed position of Figure 8 can perform. The drawn system boundary is intended to represent that only one slider 5b of the upper fitting part can be used. This one slider then has the one (single) Ausstellarm 20 b ', which in the preferred example additionally with a

Locking function 17b ', 30a' is provided, this on the shorter auxiliary handlebar 30 '.

Outside the said system boundary, that is to say on the right in FIGS. 7, a further slider 5a can be provided.

The one-armed embodiment of the figures 7 shown can be provided with a short mounting rail 28 ', which can be arranged at (horizontal) height above the gripping area of the wing there. This results in no closed parallelogram, as would be the case in the presence of two Ausstellarmen and the long connecting rod 28. The wing is guided here at only one point from the upper fitting part 5 with the sliding member 5b '.

In a further example, not shown separately, the latching function via the second auxiliary link 30 'can also be omitted and, for example, assigned to the lower fitting part, corresponding to FIGS. 2a, 2b with the associated carriages.

The energy absorption of the springs 25, 15 as examples of a respective energy storage unit E can be coordinated with one another at the top and one at the bottom, in the context of their spring characteristic (s).

In other words, when the spring is loaded by swinging out of the turn-off arms, a characteristic is followed that is essentially the same for above and below.

Figures 3a and 3b show the lower fitting part 4 with the carriage 4b and 4a in the (locked) closed position of the opening arms. A comparison of the length b _{2 of} the spring 15 in the closed position of Figure 3b, which corresponds to the sealed closed position of the associated wing, with the length b _{0 of} the spring in the raised position of the Ausstellscheren in Figures 2a, 2b shows that the length b _{2 of} the spring is significantly greater than the length b _{0 of} the spring.

This means that the bias of the spring 15 in the closed position of the arms (and the wing) is significantly lower than in the parked (latched) open position of the

Raising arms. The stored energy is released as a force as soon as the end of the closing-sliding movement of the lower fitting part 4a, 4b, the blocking of the Release scissors released and the Ausstellscheren (and thus the wing) are moved from the parked (latched) position in the sealed (locked) closed position. This pressing movement, which is caused and executed by the operator - in particular via the handle 3 - is noticeably supported by the stored energy of the compression spring which is now released.

This is helpful because the pressing operation of the wing in its sealed closed position requires much more force than the Abstellbewegung. The latter is already facilitated because the compressed in the closed position sealing elements the

Shutdown when unlocking the wing to push it out of the sealing position, while pressing the wing must be pressed against the resistance of the sealing elements at the end of the Andrückens.

The Abstellbewegung is also facilitated by the fact that the wing, especially for heavy wings, has the inclination, from the closed position, after unlocking the handle,

"fall out", so to meet the user a little. The extension arms are loaded by the high weight and slightly lower, so that it is a downhill movement for the wing, which can be more easily led out of the frame and its closed position. The energy also released thereby absorbs the energy storage unit, additionally supplemented by the pulling force of the user who pulls the wing out of the closed position. The energy storage unit does not support the

Opening movement, but takes from this opening movement their energy to be stored, in the form of potential energy, and stores them first in the Verrastungszustand the Ausstellarme, which were explained in more detail with reference to FIG 5.

This applies regardless of whether the energy storage unit E is arranged on the lower fitting part 4 or on the upper fitting part 5. It is advantageous that it is assigned to each of the rear carriage 4a and sliding element 5a.

Preferably, an energy storage unit, as shown in the figures, mounted both on the lower fitting part 4 and the upper fitting part 5, in particular when used on so-called parallel sliding wings. As a result, the Einschwenkbewegung be improved in terms of their parallelism.
