    Slide brake (11) for turnable windows, doors or shutters, which windows, doors or shutters consists of a frame (1), with one lower part (2), one upper part (3) and two lateral parts (4). In those lateral parts a casement (5) for instance a window casement, is pivoting suspended by two mirror symmetrical equal swinging arm assemblies (6). The lateral parts (4) of the frame includes each at least one slide groove (7), in which a slipper (10) is provided to slide with a certain friction. This slipper (10) is in turn articulated attached to the upper element (8) of the window casement, via the upper assembly (9) on the respective short side of the upper element. The friction between the slipper (10) and its surrounding surfaces are larger in at least one subarea, in the slide groove (7), compared to the friction in other parts of the slide groove (7), by that the slide groove (7) in the subarea comprises a constriction, which brakes the slipper (10) in the subarea, whereby a continuously and automatically disengageable airing blocking device is obtained.

    Top fittings, which are articulated with a sliding shoe. The sliding shoe in turn is arranged to run in the sliding groove along the extent of the side frame, the top piece of the window being guided to a nearly linear movement along the side frames, while the bottom part of the window frame is allowed to pivot from the closed position of the window to its inverted position. closed mode. The sliding groove usually comprises a sliding rail of, for example, plastic, and in that case the sliding shoe runs in this sliding rail with more or less friction between the sliding shoe and the surrounding surfaces of the sliding rail.
    From a safety point of view, pivoting windows must be fitted with a so-called child lock / child lock which ensures that the window cannot be opened more than the nun prescribes (Sweden 100 mm) at the bottom, without first releasing this fuse or lock and then allowing the window to be opened further. . This is a safety measure to prevent mainly small children from being able to open the window and fall out. Furthermore, it is common to provide the construction with some form of ventilation barrier which prevents the unwanted closing or opening of the window, as the same is exposed to, for example, wind pressure, negative pressure or transverse draft. There is also a risk of crushing damage if the window can close uncontrollably.
    Known solutions of the above type are, for example, SE 8902843-5 where a swivel fitting is provided with a teddy bear lock and a separate ventilation lock.
    The child lock then consists of a plate with a reading recess in the form of a guiding groove and a nose, which nose guides a holding member in the form of a shoulder cut into the groove and the groove has a rest position for the rivet in the closed position of the window and a locking position for the window's child safety. This solution has a separate ventilation barrier in the form of a fold-out arm, which, usually in the child-locked position, falls out and is clamped between the window frame and the frame, whereby the window is prevented from being involuntarily closed.
    With the ventilation lock extended in combination with the child lock, the window is locked for movement both outwards and inwards in relation to the frame. The Norwegian NO 320116 is further based on the Swedish patent's child restraint, but differs from this in that instead of the separate fold-out arm, an extra deep groove has been inserted in the child restraint in connection with the child restraint position, whereby a fixed, locked position is obtained where the window is locked in both directions. In this way, both child restraint and ventilation lock have been obtained with one and the same detail.
    The mentioned solutions but also other constructions of the above kind are, however, encumbered with fl your shortcomings and inconveniences. In one of the above-mentioned solutions, the ventilation lock consists of two details, the lock together with the child lock, which means that the air lock does not work fully fully if the child lock is not active, the air lock is at least partially dependent on the child lock. Although the second solution consists of a detail, it has the disadvantage that it always gets stuck in the ventilation position, regardless of whether this is desired or not, after which the latch must also be operated in order to be able to close the window. None of these older solutions are automatically disconnectable regarding the ventilation mode but must be operated in one way or another before the ventilation function is switched off.
    Another problem with existing latches is that they offer only a single fixed ventilation position, given the design, dimensions and location of the latch / latches and that this ventilation position is only offered with an opening that is less than or equal to the maximum opening dimension in the child lock position.
    Furthermore, these locks must therefore be operated in one way or another, in order to be disconnected, ie even when you want to close the window, the locks in these solutions must be manually disengaged before the window can be closed.
    Description of the invention The present invention achieves the object of solving the above problems in the device of the type stated in the preamble of claim 1.
    The ventilation mode in the present invention is in no way dependent on the teddy bear barrier, which the older solutions are in one way or another. The complete construction comprises a teddy bear lock, but it is completely disengaged from the air lock and the ventilation function is achieved by a separate slide brake.
    Reversible windows comprise, as described above, at least one sliding track or sliding guide arranged in the respective side frame. In each sliding groove a sliding shoe is arranged to run, during the movement of the window between its closed and its inverted position, and the top piece of the window is thus guided according to a nearly linear movement along the sliding groove, because the sliding shoe is hingedly attached to the top fittings. . In older solutions, the sliding shoe is arranged to slide easily along the entire length of the sliding groove so that the window is easy to maneuver when opened and turned in all positions. In the present invention, the sliding shoe slides easily in predetermined portions, while the friction in at least one portion, a sub-area, is greater than in other parts of the sliding track. This is made possible by the sliding groove in the sub-area comprising a constriction, which in this way is local in the sub-area.
    Through this method, a braking force, an increased friction, arises between the sliding shoe and the sliding track, in this sub-area, which has the consequence that the movement of the sliding shoe is slowed down when the sliding shoe enters this sub-area. This results in a braked position for the window frame, a ventilation position, in that its top piece is hingedly connected to the sliding shoe. The local constriction in the sub-area determines how sluggish the sliding shoe should run in the area. By adjusting the effect of the constriction on the cross section, the friction is selected so that it is sufficiently sluggish for the ventilation function, ie that the friction is able to keep the window in the selected position without wind forces and the like changing the position of the window frame, but still not too sluggish to maneuver it. when opening or closing.
    Overall, the function is such that at the opening of the window, i.e. for a distance initially at the opening of the arch, the movement is easy, because the sliding groove in this area does not involve any penetration, to then go sluggishly during a section, when the sliding shoe passes the constriction, and when the sliding shoe has then passed the constriction, the continued opening movement is easily repeated. It should also be mentioned that somewhere during the opening movement the bamboo lock 10 is arranged to come into force. Due to the present invention, a stepless ventilation barrier has thus been obtained, with a large number of ventilation positions obtained and where the ventilation barrier is automatically "disengageable", ie it is possible to close or open the window frame more or less even though the ventilation barrier is active.
    Thus, as in previous solutions, it is not necessary to operate the ventilation lock in the ventilation mode to disengage it. Furthermore, it is not limited to the ventilation positions being within the child lock's maximum limit for opening dimensions, which was previously the case.
    According to a preferred embodiment of the invention, the sub-area, comprising the constriction, is placed along the sliding track in a selected and tested position, whereby the ventilation position occurs where it is desired that the function should take effect.
    According to the embodiment, this preferably occurs somewhat before the latch in the child lock function engages with the holding means arranged for the child lock, and the stepless ventilation position is then in operation preferably a bit past the child lock position. This means that the ventilation mode can be used before the child lock locks further opening possibilities and if a larger opening for ventilation is desired, the child lock is disengaged, and thus a further distance is available for any ventilation mode. Of course, the ventilation lock also works in the child-secured position when the window frame is locked for outward movement via the child lock and sluggishly movable for inward movement via the ventilation function. However, the subdivision does not limit the location of the sub-area with its narrowing, to the one described above, but the sub-area's location along the sliding track can be chosen to suit the intended application, within the scope of the subdivision. Thus, one is not limited to the fact that the ventilation mode can only take place within the child-locked maximum opening dimension, which is the case in previous solutions.
    According to a preferred embodiment of the invention, the length of the subarea with its constriction is selected and tested, the braked, stepless ventilation position of the frame being active during as much of the window frame movement as desired for the application in question. By determining the outer positions of the constriction along the sliding track, the desired ventilation position is selected. Previous solutions present only one, fixed ventilation mode, which is not selectable. In addition, the ventilation barrier in the older solutions must be disengaged, which is not needed in the present invention.
    According to a further embodiment, the friction in the sub-area is increased by arranging a sliding brake in connection with the sliding groove, which sliding brake acts on the cross-section of the sliding groove, whereby a local narrowing is obtained. Either the sliding brake can be mounted so that it is the sliding brake that directly encroaches on the cross section and then comes into contact with the sliding shoe at the passage, alternatively that the sliding brake affects a sliding rail arranged in the sliding groove so that it narrows in the sub-area. the passage of the sliding shoe is made more difficult by the narrowing of the sliding rail in the subarea. According to the preferred embodiment, the sliding groove comprises this sliding rail of plastic or similar suitable material and preferably the sliding brake is fitted against the opposite wall of the sliding rail and thus the increased friction occurs in the area in the contact between the sliding shoe and the sliding rail wall, at the passage. By mounting the sliding brake in an adapted position, transversely in relation to the sliding groove and the sliding rail, the friction in the sub-area is determined, whereby the desired brake fi is obtained in the sub-area, and thus a well-balanced restraining force in the ventilation position.
    As a result, a stepless ventilation barrier has been created.
    According to a further preferred embodiment, the sliding brake is displaceable transversely in relation to the extent of the sliding groove, and thus the friction is adjustable in the sub-area. The sliding brake acts on the cross section of the sliding groove and by displacing the sliding brake, mainly transversely in the direction of or from the sliding groove, the cross section for the passage of the sliding shoe is increased or decreased and a reduced or increased friction / braking force is obtained in the subarea. Older solutions do not offer any similar adjustable arrangements at all, but are only fully read and must also be disengaged manually.
    According to a further embodiment, the sliding brake has an L-shaped cross-section, an angular shape, i.e. two legs with an intermediate angle of preferably 90 ° and preferably the sliding brake is a sheet metal or plastic part. The first leg of the sliding brake is arranged to act on the cross section of the sliding groove, the sliding brake interfering with the possible passage of the sliding shoe in the subarea - a local constriction is obtained, and the second leg comprises recesses or fls arranged for mounting an angular part against the side part of the frame. Either the sliding brake can be mounted so that it is the sliding brake that directly encroaches on the cross section and thus comes into contact with the sliding shoe at the passage, or alternatively that the sliding brake is fitted between the sliding groove and the sliding rail arranged in the sliding groove. According to the preferred embodiment, the sliding groove comprises a sliding rail of plastic or similar suitable material and preferably the first leg of the sliding brake fits between one wall of the sliding groove and the opposite wall of the sliding rail and thus the increased friction in the area in contact between sliding shoe and sliding rail wall.
    By mounting the sliding brake in an adapted position, transversely in relation to the sliding groove, the friction in the sub-area is determined, whereby the desired braking force is obtained in the sub-area, and thus a well-balanced restraining force in the ventilation position. Alternatively, of course, the thickness of the first leg, which affects the cross section of the sliding groove, can be adjusted so that the same result is obtained. As a result, a stepless ventilation barrier has been created, which is also simple and possible to assemble afterwards to supplement an existing installation, without the window construction necessarily being prepared for this function. This is very difficult in older solutions. In a preferred embodiment, the sliding brake is displaceable transversely in relation to the extent of the sliding groove, and thus the friction is adjustable in the sub-area, in that the sliding brake comprises one or two recesses, which are inclined and preferably oval. By coordinating these recesses with the fastening devices used for attaching the slide brake to the frame, it is possible to displace the slide brake slightly in the direction of the slide groove, upwards towards the upper part of the frame or downwards towards the lower part of the frame, the slide brake simultaneously displacing transversely or from the sliding groove, thanks to the inclined recesses, whereby the cross section for the passage of the sliding shoe is increased or decreased with a reduced or increased friction / braking force as a result. Thus, a stepless and automatically disengageable ventilation lock has been provided, which also has adjustable friction. Older solutions do not offer any adjustable alternatives at all, while the current invention is adjustable, both when adjusting the braking force initially in connection with delivery or installation, and also at a later stage if the need or desire for an adjusted brake caliper arises.
    According to a further preferred embodiment, the sliding brake is displaceable transversely in relation to the extent of the sliding groove, and thus the frictional force is adjustable in the sub-area, in that the sliding brake comprises one or more recesses, which are preferably coordinated with one or two eccentric devices. . By turning the eccentric devices, a displacement of the sliding brake will take place, mainly transversely in the direction of or from the sliding groove, whereby the cross-section for the passage of the sliding shoe is increased or decreased, whereby a reduced or increased friction / braking force is obtained.
    Hereby a stepless and automatically detachable ventilation barrier has been obtained where the same advantages as described above in relation to older solutions are achieved. In a further preferred embodiment, the sliding brake comprises, in whole or in part, an excipient material, preferably rubber. When the slide brake is arranged, preferably in a recess, next to the slide track, the slide brake has more or less or no effect at all on the cross section of the slide track, by allowing the slide brake to expand, as a result of the slide brake being compressed. Because the position of the sliding brake and thus its fixed position next to the sliding rail is tested for reasonably large braking force, further expansion means that the side of the sliding brake, against the sliding groove arranged, further affects / intrudes on the sliding track cross section, which increases the local constriction in the subarea. The sliding brake is preferably compressed in that fastening devices which firmly arrange the sliding brake against the frame comprise cantilevered portions which are arranged to press against the sliding brake in the direction of the frame, so that the sliding brake expands corresponding to how hard the fastening devices are arranged against the frame. Preferably, the sliding brake comprises at least one recess, through which recess, preferably a screw, is inserted, and this screw is screwed in against the frame to fasten the sliding brake to the frame. Because the screw comprises a cantilevered part, preferably a screw head, which is large enough to press on the edges of the recess, the sliding brake expands, due to its elasticity, under the influence of the pressing force from the screw head, and the harder the screw is applied to the core, the more expands. the sliding brake. In this way, the effect of the sliding brake on the cross section of the sliding groove in the sub-area becomes adjustable, whereby the friction increases or decreases, depending on the degree of expansion of the sliding brake. The sliding brake can either be arranged so that it comes into direct contact with the sliding shoe, when the sliding shoe passes in the sliding groove, the adjustable braking force occurring between sliding shoe and sliding brake, alternatively the sliding brake can be fitted to the aforementioned sliding rail. the expansion of the sliding brake, and the adjustable brake screw står then arises between the sliding shoe and the wall of the sliding rail in the subarea. The number of recesses in the sliding brake is not limited to only one, but preferably the recesses fl are the number whereby an increased fl flexibility is obtained. This provides an adjustable braking force in the device according to the embodiment, which is lacking in older solutions and a stepless and automatically disengageable ventilation barrier is thereby obtained.
    In a further preferred embodiment, the sliding brake comprises two parts, a thin-walled housing with preferably wedge-shaped side walls, and a wedge-shaped core, which core is slidably arranged in the housing. When the complete slide brake is arranged, preferably in a recess, next to the slide track, the slide brake has more or less or no effect at all on the cross section of the slide track, by allowing the slide brake to expand to different degrees in the direction of the slide track. When the sliding brake encroaches on the cross section of the track, in the sub-area, the available passage for the sliding shoe decreases, which is thus braked in the sub-area. The sliding brake can either be arranged so that it comes into direct contact with the sliding shoe, when the sliding shoe passes in the sliding groove, the adjustable braking force occurring between sliding shoe and sliding brake, alternatively the sliding brake can be fitted to the aforementioned sliding rail. the expansion of the sliding brake, and the adjustable braking force then arises between the sliding shoe and the wall of the sliding rail in the subarea. The wedge-shaped core comprises continuous recesses, which are preferably used in the mounting of the sliding brake against the side parts of the core, by means of fastening devices, for example screws, being inserted through the recess (s), and then screwed into the core.
    As a result, the sliding brake is fixedly mounted against the frame in a preferably tested position. Because the wedge-shaped core is displaceably arranged in the housing, in the direction in / out of the frame in the mounted position of the slide brake, the walls of the core affect the surrounding thin and wedge-shaped walls of the housing, depending on the position of the core in the housing. Depending on how deep the core is screwed into the housing, the thin, wedge-shaped walls of the housing are pushed out, more and more the deeper the core is screwed into the housing, towards the frame, due to the wedge-shaped cross-section of the core, and thus the sliding brake expands more and more. 10 15 20 25 11 The friction in the sub-area thereby becomes adjustable, since the position on the core is adjustable. Because the position of the sliding brake and thus its fixed position next to the sliding rail is tested for a reasonably large braking force, further expansion means that the side of the sliding brake, against the sliding groove arranged, further affects / intrudes on the sliding groove cross section, which increases the local constriction in the subarea, and thus also the friction. Conversely, the friction in the sub-area decreases with reduced expansion. Thus, an adjustable ventilation latch is provided in the device according to the embodiment, which is missing in older solutions and a stepless and automatically disengageable ventilation latch is thereby obtained.
    In a preferred embodiment, the first leg of the sliding brake has a conical cross-section and the sliding brake is also slidably arranged in the inward direction and / or outwards in relation to the side parts of the core. By displacing the sliding brake, for example inwards towards the frame, and where the cross-section of the first leg ~ for example has a pointed shape, i.e. the leg is widest near the base and narrowest at its outer end, the first leg then affects more and more the cross-section of the sliding track, want to saw takes up more space in the sliding track, and thus increases the friction in the sub-area. Conversely, in this arrangement, the friction decreases in the event that the sliding brake is displaced outwards relative to the core. The first leg can be fitted either directly in the sliding groove or between one wall of the sliding groove and the corresponding wall of the sliding channel. Thereby an adjustable braking force is obtained in the device according to the embodiments, which is lacking in older solutions.
    Of course, the design / conicity of the cross-section may be the reverse, the function described above being reversed, when moving towards and from the vessel.
    In a preferred embodiment of the invention, the sliding brake comprises a toothed side, which faces the sliding groove. Correspondingly, the sliding shoe according to this embodiment also comprises a toothed side, which in turn faces the sliding brake. Since the sliding brake is arranged at the sliding track, in a tested position, the two teeth will cooperate and grip each other, when the sliding shoe passes the sliding brake, whereby a tested and increased friction occurs in the sub-area including the sliding brake, relative to the friction in other areas. Preferably, the sliding brake in this case is an L-shaped, angular detail in plastic or sheet metal, according to the previous embodiment, where the first leg, which is arranged to act on the cross section of the sliding groove in the sub-area of the sliding brake, is provided with the toothing. Where applicable and according to the preferred embodiment, the sliding groove comprises a sliding rail and then the first leg fits into the sliding rail itself, so that the sliding shoe with its toothing and the first leg with its toothing, come into contact with each other and the friction thus increases in the subarea to other areas. A stepless and automatic ventilation lock has thus been obtained.

    The constructive design of the present invention is described by the following detailed description of embodiments of the invention with reference to the accompanying figures which show a preferred, but not limiting, exemplary embodiment of the invention. In addition, the invention advances the state of the art in the field in various respects. This is realized in the present invention in that a device of the type described below is substantially as described in the characterizing part of claim 1.
    Detailed description of the figures Fig. 1a shows a section through the upper part of a jug 1 which comprises a lower part 2 (not shown), an upper part 3 and two side parts 4. In the side parts 4 of the frame 4 an arch 5 is pivotally suspended by means of two mirror-symmetrically equal pivot fittings complete 6 which on each side of the frame are hingedly attached to the side parts of the frame. At each end of the top piece 8 of the arch, a top fitting 9 is arranged, which top fitting is hingedly attached to a sliding shoe 10.
    The sliding shoe 10 is arranged to run in a sliding groove 7, which sliding groove is preferably a milled groove in the side parts 4 of the frame, the right and the left side part, respectively.
    The sliding groove 7 comprises a sliding rail 12, preferably of plastic, which is arranged in the sliding groove 7. At the upper part of the sliding groove 7, at a distance from the upper part of the frame, an L-shaped sliding brake 11 is arranged, which sliding brake by its first leg 13 delimits the cross section along the length of the leg, whereby a constriction occurs in the subarea. When the lower part of the frame 5 is moved outwards or inwards relative to the frame 1, the top piece 8 of the frame follows a linear movement along the sliding grooves 7 due to the guide of the top piece 8 by means of the top fittings 9 and the articulated sliding shoes 10 in each side part. respective sliding shoe 10 is located above the sliding brake 11, the sliding shoe 10 runs easily, as the friction between the sliding shoe 10 and the sliding rail 12 in this area is low.
    When the sliding shoe then enters the sub-area, in which the sliding brake 11 is arranged, the friction between the sliding shoe 10 and the sliding rail 12 increases, due to the sliding brake acting on the cross section in the sub-area so that it decreases. When the sliding brake ll is passed, the friction is low again and the sliding shoe runs easily.
    The friction in the subarea is selected so that the ventilation function becomes the desired, i.e. intended inertia is achieved, the arch remaining in the selected ventilation position, but still disconnectable by the arch 5, by hand force fl being moved outwards or inwards towards the core 1.
    Fig. 1b shows an enlargement of the upper part of one side part 4 of the frame 1, more precisely the right side part with an example of the sliding brake 11 arranged at the sliding groove 7, and the top fitting 9, which is articulated to the sliding shoe 10. To minimize wear on the sliding shoe 10, in its passage at the sliding brake 10 15, preferably fits the first leg 13 of the sliding brake 11 between one side wall of the sliding rail 12 and the corresponding side wall of the sliding groove 7, whereby a sharp edge against the first leg 13 of the sliding brake 11 is avoided. The second leg 14 of the sliding brake 11 is arranged to be mounted against the side part 4 of the frame with some form of fastening device 20, for example screw 26 or the like.
    Figs. 2a-b show the upper part of the frame 1 with a section through the upper part 3 of the frame, and further the right side part 4 of the frame 1 in which the sliding groove 7, with its sliding rail 12, is arranged. Figure 2b shows an enlargement of the area around the sliding brake 1 1. At a smaller distance from the upper part 3 of the frame and in connection with the sliding groove, the sliding brake 11 is fixedly arranged against the side end 14 of the frame. The distance from the upper part of the frame is chosen so that the arch 5, when opened from the closed position, has an unbraked distance before the sliding brake 11 brakes the movement. The length of the sliding brake 11 is adapted so that the braking length of the sub-area with the increased friction, it is intended, whereby the outward or inward movement of the arch 5 is thereby braked and the stepless ventilation function is thus active and of the desired length.
    Furthermore, the upper part of the swingarm fitting 6 and the top fitting 9, which is hingedly attached to the sliding shoe 10, are shown. The sliding groove 7 with its sliding rail 12 is coordinated with the sliding shoe 10 so that the friction between the sliding shoe 10 and the sliding rail 12 is easy to maneuver. its closed and inverted position, except in the selected sub-area, where the sliding brake ll is arranged. In this sub-area, the slide rail 12 is compressed somewhat due to the fact that the slide brake 11 according to the mold is designed as an L-shaped slide brake, the first leg 13 of which is fitted between one side wall of the slide track 7 and the corresponding side wall of the slide rail 12. Furthermore, the second leg 14 is arranged with slightly inclined and elongate recesses 19 in which fastening devices, for example screw 26, are arranged for the fixed device of the sliding brake against the side part 4 of the frame. The screw together with the inclined recess 19 enables adjustability by sliding the sliding brake 11 up or down along the side part 4 of the frame, whereby the sliding brake is simultaneously moved transversely in the direction of or from the extent of the sliding groove 7. The first leg 13 of the sliding brake 11 then presses, more or less depending on how the sliding brake is displaced, against the wall of the sliding rail 12, whereby the available cross-section for the passage of the sliding shoe 10 changes and thus the friction in the area changes.
    Figs. 2c-d show a section A-A through the right side part 4 of the jug, the sliding brake 11 and the sliding shoe 10 and a detailed view of the sliding groove 7, comprising the sliding rail 12, and the position of the sliding brake 11 between these parts. Furthermore, the top fitting 9 and its articulated attachment to the sliding shoe 10 are shown. In the embodiment shown, an L-shaped sliding brake 11 is arranged, which sliding brake through its first leg 13 acts locally on the cross section in this sub-area, whereby a constriction occurs in the sub-area. The fastening device in the exemplary embodiment shown are screws 26, which firmly arrange the sliding brake 11 against the side part 4 of the frame. The first leg 13 of the sliding brake 11 is fitted between one side wall of the sliding groove 7 and one wall of the sliding rail 12 and then presses, more or less depending on how the sliding brake is set. , against the wall of the slide rail 12, the available cross-section for the passage of the slide shoe 10 changing and thereby changing the friction in the area.
    Figs. 3a-d show an embodiment of the sliding brake 11, arranged at the sliding groove 7. In this embodiment, the sliding brake 11 is an angular plate or plastic part, comprising the two legs 13, 14, preferably at an angle of about 90 degrees between the legs. The first leg 13 is arranged, preferably between one wall of the slide rail 12 and the corresponding wall of the slide groove 7, and the second leg 14 is formed with folded fl edges 27 which are arranged for anchoring the slide brake 11 against the side part 4 of the slide 10. is preferably pushed towards the side part 4 of the frame, whereby the sliding brake 11 is fixedly mounted in the position along and in relation to the sliding groove 7 desired for the current application, and this position is as previously described, selectable both for the longitudinal position along the sliding groove 7 and the transverse the position towards the sliding groove 7 so that the desired friction is obtained.
    By fitting the first leg 13 between one wall of the slide rail 12 and the corresponding wall of the slide track 7, the available dimension for the passage of the slide shoe 10 is limited and thus the friction between the slide shoe 10 and the slide rail 12. The length of the slide brake 11 is selectable, to enable individual choices of the size of the ventilation mode.
    Figs. 4a-d show an embodiment of the sliding brake 11, arranged at the sliding groove 7. According to the embodiments, the sliding brake 11 is an angled plate or plastic part, comprising the two legs 13, 14, preferably at an angle of about 90 degrees between the legs. The first leg 13 is arranged, preferably between one wall of the sliding rail 12 and the corresponding wall of the sliding groove 7, and the second leg 14 comprises the spokes 27 which are arranged for the sliding brake 11 to be anchored to the side part 4. These spokes 27 are preferably driven or pushed against the side part 4 of the frame. more precisely in one side wall of the sliding groove 7, whereby the sliding brake 11 is fixedly mounted in the position along and in relation to the sliding groove 7 which is desired for the current application. This position is, as previously described, selectable both with respect to the longitudinal position along the sliding groove 7 and the transverse position towards the sliding groove 7 so that the desired friction is obtained.
    The first leg 13 preferably has tapered and beveled ends 28 to achieve a smoother transition between the unaffected slide portion 12 and the sub-area in which the slide brake 11 is arranged and which thus includes the constriction. By fitting the first leg 13 between one wall of the slide rail 12 and the corresponding wall of the slide groove 7, the slide rail 12 is thus compressed slightly and the available dimension for the passage of the slide shoe 10 is reduced, thereby increasing the friction between the slide shoe 10 and the slide rail 12. The length of the slide brake 11 is according to inventive tank Selectable, to enable individual selection of the size of the ventilation mode. In addition, of course, the thickness of the first leg 13 according to the inventive idea is selectable, whereby the friction is adapted to be the one desired for the application.
    Figs. Sa-d show an embodiment of the sliding brake 11, arranged at the sliding groove 7. Also in this embodiment, the sliding brake 11 is an angular plate or plastic part, comprising the two legs 13, 14, preferably with an angle of about 90 degrees between the legs. The first leg 13 is arranged, preferably between one wall of the slide rail 12 and the corresponding wall of the slide groove 7, and the second leg 14 comprises the slightly inclined, elongate recesses 19 which are arranged for fastening devices of conventional type, for example screw 26 or the like.
    The sliding brake 11 is preferably screwed to the side parts 4 of the frame in the position along and in relation to the sliding groove 7 desired for the current application, and this position is, as previously described, selectable both for the longitudinal position along the sliding groove and the transverse position towards the sliding groove 7. so that the desired friction is obtained.
    From this starting position, the frictional force is then adjustable in the subarea at the sliding brake 1 1, by loosening something on the fastening devices, screws 26, and then tapping, pushing, or in another way affecting the sliding brake 11, upwards or downwards along the side part of the frame 4, whereby the sliding brake 11 will be moved in the direction of or from the sliding rail 12, due to the recesses 19 being inclined, whereby the sliding rail 12 is compressed slightly and the available dimension for the passage of the sliding shoe 10 is reduced and thus the friction between the sliding shoe 10 and the sliding rail 12 - an adjustable friction has thus been obtained. After the friction / braking force has been set as desired, the sliding brake is screwed back against the side part 4 of the frame. The length of the sliding brake 11 is selectable according to the invention, to enable individual selection of the size of the ventilation position.
    Figures 5e-g show an embodiment similar to that described in Figures 5a-d. Also in this embodiment the sliding brake 11 is an angular plate or plastic part, comprising the two legs, 13, 14, preferably at an angle of about 90 degrees between the legs. The first leg 13 is arranged, preferably between one wall of the slide rail 12 and the corresponding wall of the slide bar 7, and the second leg 14 comprises recesses 15 which are arranged for eccentric devices 16, not further described. Through these eccentric devices or alternatively through other recesses 29, specially arranged for anchoring the sliding brake, the sliding brake 11 is screwed against the side parts 4 of the vessel in the position along and in relation to the sliding groove 7 desired for the current application. This position is, as previously described, selectable both with respect to the longitudinal position along the sliding groove and the transverse position towards the sliding groove 7 so that the desired friction is obtained.
    Because the eccentric devices 16 are rotatable and eccentric, the sliding brake 11, upon rotation of the eccentrics, will move in the direction of or away from the sliding rail 12, whereby the sliding rail is compressed slightly and the available dimension for sliding shoe 10 passage is reduced and thus increased. the friction between the sliding shoe 10 and the sliding channel 12 - an adjustable friction has thus been obtained. According to the inventive concept, the length of the sliding brake 11 is selectable, in order to enable individual choices of the size of the ventilation position.
    Figs. 6a-c show an embodiment of the sliding brake 11, in which this wholly or partly comprises an excipient material, preferably rubber. According to this embodiment, the sliding brake is arranged in a recess in the side part 4 of the frame, preferably a milled groove 18, with an open side towards the sliding groove 7 and the sliding rail 12. The sliding brake 11 also comprises a number of recesses 17, arranged for carrying a screw 26 per recess for the attachment of the sliding brake 11 to the side parts 4 of the frame. The sliding brake is mounted in a milled groove 18 and this position is adapted so that the effect on the available passage for the sliding shoe 10 is achieved a greater friction in the subarea with the sliding brake 11. the ventilation lock is obtained. During assembly, the screws 26 are tightened with an adapted force and in coordination with the location, this allows the reasonably large braking force. The frictional force becomes adjustable by the screws 26 being tightened harder against the side parts 4 of the frame, the screw heads pressing against the flat surfaces 25 of the sliding brake 11, which surround the recesses 17, so that the sliding brake expands due to the pressing force. As a result, the sliding brake 11 expands out into the sliding groove 7, alternatively towards the sliding rail 12, whereby a constriction is formed along the sliding brake 11 and the available passage for the sliding shoe 10 decreases and thus the friction between sliding shoe and surrounding parts is increased. . Figs. 7a-d show an embodiment of the sliding brake 11, where it comprises two parts, a thin-walled housing 21 and a wedge-shaped core 22, which core 22 is slidably arranged in the housing 21. The sliding brake 11 is arranged in a preferably milled groove 18, next to the sliding groove 7, with an open side towards the sliding groove 7 and the sliding rail 12. Due to this location the sliding brake has more or less or no effect on the cross section of the sliding groove 7, by allowing the sliding brake ll to expand to different degrees towards the sliding groove 7 When the sliding brake encroaches on the cross section of the sliding track 7, in the sub-area, the available passage of the sliding shoe 10, which is thereby braked in the sub-area, decreases.
    According to the embodiment, the sliding brake 11 is fitted against the sliding rail 12, which is compressed in the sub-area under the influence of the expansion of the sliding brake 11, and the adjustable braking force then arises between the sliding shoe 10 and the wall of the sliding rail 12 in the sub-area. The wedge-shaped core 22 comprises continuous recesses 24, which are used in the attachment of the sliding brake 11 to the side parts 4 of the frame, by fastening devices, for example screw 26, being inserted through the recess / recesses 24, and then screwed into the side part 4 of the frame. ll fixedly arranged against the core in a preferably tested position. Because the wedge-shaped core 22 is displaceably arranged in the housing 21, in the direction towards / out of the frame in the position of the sliding brake 11, the walls 22 of the core 22 affect the surrounding thin and wedge-shaped side walls 23 of the housing 21, depending on the position of the core 22 in housing. Depending on how deep the core 22 is screwed into the housing 21, the thin and wedge-shaped side walls 23 of the housing are pushed out, more and more the deeper the core 22 is screwed into the housing 21, in the direction of the core 1, and in that way expands. the sliding brake ll more and more. The friction in the sub-area thereby becomes adjustable, since the position of the core 22 is adjustable.
    Because the location of the sliding brake 11 and thus its fixed position next to the sliding rail 12 is tested for a reasonably large braking force, further expansion means that the side of the sliding brake 11 further affects / interferes with the cross section of the sliding groove 7, which increases the local constriction in the subarea. 22 and thus also the friction. Conversely, the friction in the sub-area decreases with reduced expansion. Thereby an adjustable ventilation barrier is provided in the device according to the embodiment.
    Figs. 8a-b show an embodiment of the sliding brake 11, where it comprises a toothed side 30, which faces the sliding groove 7. Correspondingly, the sliding shoe 10 preferably also comprises a toothed side 31, which in turn faces the sliding brake 11. Since the sliding brake 11 is arranged at the sliding groove 7, in a tested position, the two teeth 30, 31 will cooperate and grip each other, when the sliding shoe 10 passes the sliding brake 11, whereby a tested and increased friction occurs in the area where the sliding brake 11 is mounted, in relation to the friction in other areas. Preferably, the sliding brake according to this embodiment is an L-shaped angular part in plastic or sheet metal, where the first leg 13, which is arranged to act on the cross section of the sliding groove 7 in the sub-area, comprises the ignition 30. According to the preferred embodiment, the sliding groove 7 comprises a sliding rail 12 and then the first leg 13 is fitted in the slide rail 12 itself, so that the slide shoe 10 with its toothing 31 and the first leg 13 with its toothing 30, come into contact with each other and the friction thereby increases in the sub-area relative to other areas. Furthermore, the second leg 14 of the sliding brake 11 also comprises eccentric devices 16, in accordance with the previously described embodiment, wherein the position of the sliding brake 11, transverse to the sliding groove 7, is optionally determined, so that the desired friction is obtained. 10 15 20 1 = frame 2 = lower part of the frame 3 = upper part of the frame 4 = side parts of the frame 5 = arch 6 = swingarm fittings complete 7 = sliding track 8 = top of the frame 9 = top fitting 10 = sliding shoe 1 1 = sliding brake 12 = sliding rail 13 = first leg 14 = second leg 1 5 = recess 1 6 = eccentric device 17 = recess 18 = groove 1 9 = recess 20 = fastening device BOMB 21 = height 22 = core 23 = side walls of the housing 24 = recess 25 = p1 surface 26 = screw 27 = fl ik 28 = facade end 29 = recess 30 = toothed side, sliding brake 31 = toothed side, sliding shoe
