Description

Adjustment of the mounting height of a swing sliding slide on a rolling device.

The invention relates to the subject identified by the title. A swing that can move laterally, it must be adjusted in height, which is achieved with a or various of independent claims 1 and 22, to which it makes reference.

A typical way of configuring a adjustment mechanism for height adjustment of a swinging this type is found in document EP-B845569 (Ferco) in figures 1 and in the corresponding description. A thrust and traction force that runs longitudinally in the stringer beam is converted by a surface oblique in the form of a ramp (reference numbers 15, 16 and 17 and claim 8, column 5, paragraph # 22) in a movement in height for adjusting the height position of the crossbar lower swing and, thus, the entire crossbar. To this the main configuration of the transmission of a thrust / pull movement parallel to the crossbar longitudinal in an oblique motion, as explained in the EP-B563015 (Giesee) (see figure there 1, with the senses of force F1 of the force F that runs from oblique form and indications of the effect in claim 1, column 4, lines 42 to 47). Also in the document EP-A1116843 (Soltralu) the conversion of the horizontal movement in variation in height according to figures 5, 6, as well as the pivot arrangement according to figure 9. slightly different document EP-B5764 works (GU), from which a lever movement of an element of adjustment in a corner of a swing becomes a movement longitudinal of a vehicle, to adjust the swing height, that emerges there from the "swing lift device 6, 9, 14 "claimed. But a movement is also planned here longitudinal of the vehicle layout provided for the sliding of the swing relative to the stringer of the swing bottom, see column 3, rows 19 to 40. Finally, the EP-A195721 (Krieg et Zivy) works without the longitudinal movement, in which a screwed arrangement 35, 37, 36 oriented vertically produces a variation of the position in height of the wheel of the vehicle 14, see figures 1, 3 and 4. At the same time, the rolling roller is arranged directly in the corner of the swing.

US-A5,860,189 (An) shows the characteristics (i) to (iii) of claim 1; from alternatively it also uses features of a procedure according to claim 22, referring to a process for variation of the mounting height of a swing on a stringer that extends laterally, to adjust its mounting height and an arm housed tiltingly for this, which extends basically parallel to the lower crossbar and in which it is rotatably housed a rolling roller.

The invention is based on the objective of providing a height adjustment for a slide that can slide (laterally), which is easily accessible and smooth. Softness refers to the possibility of making adjustments and readjustments easily. Smoothness refers to the decrease or reduction of the force that must be applied, to achieve the movement of
adjustment (variation in height \ Deltay).

The invention proposes in this regard a device according to claim 1, which presents as a device for rolling at least one rotating roller, on which you can slide a mounted swinging sideways. This swing is mentioned for the explanation of the rolling device, because it is the only point provided as a place of assembly (the lower crossbar horizontal) for the rolling device.

Also the adjustment procedure according to the Claim 22 fulfills the preceding objective. A swing arm  which extends along the bottom stringer beam -in assembled state- can be adjusted according to the invention from one direction vertical in its angular position, with whose angular position, when less, a roller arranged in the swingarm varies in its position in height with respect to the lower crossbar (claim 22).

At the same time, the swing arm does not move longitudinally, but it comes from a bearing support arranged on the lower beam in a still state mounted, on whose bearing support a support point is provided that allows the variation of the tilting position. None is used ramp, turning a longitudinal movement into a movement thrust by sliding housing. Varies one position swingarm with which the variation of the position is achieved in height.

This solution has other advantages, which give as result in a minor propensity for breakdowns due to the number of parts of extremely reduced assembly, so that a technique is used safer with a rolling element loaded with a weight of raised swing

In this way, a softness is also achieved of height adjustment, so that the tilting position of the adjustable arm, without reaching Additional friction or friction at sliding points. This position tilting can be influenced very directly by the area of vertical stapling, so that forces of maximum lever Preferably, the end of the adjustable arm it is arranged near the lower side member and the support of bearing, which must be firmly mounted on the lower beam, to a considerable distance from it. Between both points, the point tilting but not sliding support at one end of the arm Adjustable and the access point of the vertical regulation mechanism at the other end of the lever, at least one roller is provided rotating, on which the swinging moves in order to lateral movement, supported on a rolling guide. Roller swivel is rotatably housed in order to arm extension, not at either end of this arm adjustable (claim 1). The regulation mechanism varies the tilt position of the adjustable arm, to vary and with it Adjust the mounting height.

Only with respect to the swingarm and released from the lower beam may also indicate that the orientation of the adjustment mechanism (for mounting on the vertical beam) runs basically perpendicular to the orientation of the adjustable arm, even when it can adopt different tilting positions that with respect to the right angle, which exists Between the two orientations, they are small in size.

This regulation mechanism may be configured for mounting in a vertical slot of the swing (claim 4), with respect to the vertical beam of the swing. Here it is also very accessible in mounted state, for example, in shape of a screw mechanism, which fits from above, to be able to vary the tilting position of the low swing arm a section of lower stringer hardly accessible.

A preferred configuration of the dimension of both arm sections, which are foreseen on this side and on the other side of the rotating roller support, allows adjustment of the force conversion (claim 2). Both arm sections they don't have the extension zero; but a certain value, depending on of the selected force transmission, with respect to the variation in height obtained (claim 2, 7).

Due to the non-slip mounting of the support bearing, the swing arm does not exert any movement longitudinal (claim 5), but only a tilting movement, which with respect to the reference axis of the rolling roller obtains also a slight variation in longitudinal direction which is slightly smaller than the intended variation in height by swinging movement as for example, with respect to the distance that It should be measured from the roller axis with respect to the lower edge of the stringer (claim 5).

Basically perpendicular orientation described above of the regulation mechanism leads to the sense of adjustable adjustment basically act in the same way as the direction of adjustment of the swing (claim 6).

For adjustable arm configuration you can select a profiled shape, to configure it rigid and at the same time light. Additionally, the profile can serve to house the rolling roller, at least partially, and also so that the upper edge of the rolling roller does not protrudes above the upper edge of the swing arm (claim 8, claim 20). In this way, you can achieved by not having to go through a (metal) armor of the swinging, to accommodate a further piece of the rolling roller. A corresponding redefinition of the rolling device as such, without reference to the swing, then refers to the point of Roller bearing support, which does not protrude or, at least, does not essentially above the longitudinal side of the adjustable arm swingarm. A resting position so that this side longitudinally runs basically parallel to the edge bottom of the swing or armor, it is possible in this way without interrupt the profile of the swing or armor.

Regarding the upper longitudinal side, it is expected a lower longitudinal side of the adjustable arm that does not need be flat, but because of the profile it can be composed of two flanks of lateral support, whose lower edges can be considered as "longitudinal sides" (claim 9). This side longitudinal can -even in the form of the leading edge that is directed down described above - run obliquely, of so that it is not oriented parallel to the longitudinal side upper swing arm.

The same sizing can also be performed in reverse with respect to the arm, with the aim of increase the effective path and thereby increase the variation in possible height. If the swing arm is oblique on one side or not runs in a rectilinear way, an angle of major tilt before the outer end of the arm swingarm rubs the raceway guide.

At that point of the swing arm where the regulation mechanism acts, the angular position of the swing arm with respect to the regulation mechanism. For provide at this point a coupling that allows these variations angular position, which at the same time allows to apply a force (vertical) on the arm, a compensation mechanism is provided with the one who can afford the swinging arm movement with respect to the firm orientation of the vertical regulation mechanism (claim 14).

Preferably, a window is arranged here that allows game, in which the assumption piece is housed and held of force but a swinging movement cannot be performed compensatory with respect to the central plane of the swing arm.

Despite the force transmission of adjustable vertical mechanism, for example in the form of a screw / nut combination, you can afford the variation of the swinging position of the swinging arm, when the piece of force housing (the nut) can move or tilt apparently in the window (in the opposite direction) according to the variation of the angular position of the lever arm. This has place with vertical orientation not varied from the mechanism of regulation and nut piece oriented perpendicularly. Actually, the window tilts, for this reason, around the fixedly oriented nut.

The compensation device is especially favorable in the context of an arm profile configuration swingarm.

A vertical orientation practically invariable regulatory mechanism is obtained from its mounting on a vertical nut of a vertical leaf member (claim 24). At the same time, a squad can assume the aim of being able to orient in its vertical groove in the swing and provide a support surface that distances with a section protruding angularly, in which it can be held, by example, in the form of a screw (claim 10, 25). In this support surface, which is configured so that it protrudes, the regulation mechanism basically oriented vertically it is housed or held, on the one hand, rotatably and, on the other side, it is practically non-slip in the direction vertical, so that the force of the swing is assumed and can transmitted by angle to the vertical crossbar.

This object can be configured as pivot (claim 15) to be able to hold, for example, a head of a screw mechanism that produces the variation of height.

The determination of the force necessary for the height adjustment is done by coordinating the arm sections, which house an extension section of the total length of the swing arm (claim 2, 7). A transmission of force to minor forces results in a reduction of the possible lift path for adjustment in height, so that depending on the maximum lift path necessary coordination of both sections of arm.

Preferably that section of arm that is placed between the support point of the roller and the non-sliding mounted bearing support (claim 12).

The establishment of both arm sections in the 2: 1 ratio it offers an optimal result of the adjustment in available height and the necessary adjustment force (claim 13). Despite the smoothness of the screw setting from the vertical a sufficient lift path is achieved by the Adjustable arm tilt, which leads to an adjustment in effective swing height.

Other advantageous configurations are based on the placement of the bearing support or in its configuration for placement on the horizontal crossbar of the swing (claim 16 to 21).

It is assumed that the stringer beam presents, at least one armor placed outside and found more deep (further into the crossbar). Bearing support it can reach below the stringer armor that is find more outward or - relative to the strength of the crossbar in set- under the outer armor (found more outwards), to be able to mount preferably in the armor of the stringer beam that is further inwards (claims 17 and 18 or 16).

To do this, the bearing support in its extension in height (according to the sense of height and, in which also runs the height adjustment Δ of the swing) is greater than the maximum height extension of the swing arm.

The swing arm must not fit under the outer armor, but is outside of it (or in the sense of height and below). However, the tread wheel it can fit into a recess of an outer metal guide like armor, if not dimensioned especially small (claim 21). The expected interruption of the armor outer can be extended to allow the bearing support in the fitting fit through an enlarged opening of the armor that is further away and can be mounted on another armor that is more inward (deeper and more towards behind the crossbar) (claim 18).

A combination is also possible so that Armor interruption is only provided for introduction of the bearing support, while the support point of the Roller is positioned and the radius of the roller rolling is sized so that at this point it is not required no interruption of swing armor (claim twenty-one).

Metal parts are used as armor that are configured as stretched metal parts, especially profiled (claim 19).

In particular, in the application in profiles of plastic, in which stretched hollow spaces are configured, the reinforcements are used to reinforce the swing, for example, in shape of a U profile with a U down at least partially open, in which a profiled groove fits into the U open, in whose groove the bearing support can be mounted.

The profile can also have at least one intermediate strut, which rests on the inner bottom side of the profiled groove, so that two surface pieces are obtained which extend laterally (claim 20), which are arranged within the hollow profile and at least one of these reinforcements can improve the mounting of the bearing support, it is say set it up more rigid and firm.

While an armor opening is provided exterior (claim 16), this is the armor found more outward with respect to the inner armor, but both are preferably found within the hollow space.

The invention is explained and completed by realization examples, indicating that in the following statement it is the description of preferred examples of the invention.

Figure 1 is a perspective view of a swing F with vertical and horizontal stringer V, H, which can slide into a rack that is fixed as a rack fixed or frame B laterally. As an orientation, the positions of a leading roller arrangement 5, 6 specifically in detail, which in the other figures sinks. How orientation the direction of lateral sliding is indicated by the x and the sense of vertical height with the y, as a system of coordinates

Figure 2 shows a device of rolling as outlined above, for mounting on the lower horizontal beam H of the swing described in a view in perspective, but without the indicated place of placement previously.

Figure 3 shows a vertical section of the swing with a side view of the rolling device according to figure 2, to explain the assembly of the arrangement according to Figure 2 on the lower front surface of the stringer H of the Figure 1.

Figure 4 shows a view in the sliding direction (in the X direction) of the front surface front left of the vertical V stringer of Figure 1, in which the rolling device 6 is in a zero position, with and minimum as height adjustment as also shown in figure 3. A part of the lower beam of frame B is represented in section, to explain the location and placement of the rolling guide 15, on which the roller 6 circulates. The direction of rolling x is perpendicular to the plane of the paper, the sense of height for the Adjustment is oriented vertically.

Figure 5 shows the same view as the Figure 3, only with the maximum height adjustment y_ {2 '} or y_ {2}. Swing F has reached its maximum position in the direction and, meeting the possible adjustment height adjustment height between the representations of figure 3 and 5.

The combination shown in figure 1 of a sliding swing (with part of window and profiled guides) and a window frame, is configured so that a movement of the swing frame relative to the frame of window. At the same time, it can be a slip side. The arrangement can be configured or as a window or as a door, but it can also be transferred to others arrangements, in which an adjustment in height is desired.

The height adjustment refers to a variation of height of the swing F in direction and, maintaining its possibility of lateral sliding in an x direction in a plane, which is plotted by frame B.

To allow a sliding movement, the Swing is fastened in a roller arrangement, which is arranged on its bottom H member on one side or both sides, especially in corner areas. These provisions of roller have a bearing arm 5, which carries the roller rolling mentioned. By varying the distance of the Roller 6 from the lower front surface of the swing F can take place a previous or subsequent adjustment in the direction and to adapt the swing precisely in the frame, if necessary also to consider forces and symmetries in the area sealing, whose sealing areas in stapling are provided between the frame and the swing.

The arrangement of Figure 2 constitutes a embodiment of a rolling device, as can be located at the points identified in figure 1. Roller 6 it is housed in a support point 7, so that it can rotate freely. It has a rolling groove 6a, which is limited by two side loops 6b, adapting to the configuration of a rolling guide, as can be seen in figure 4 in section as a rolling guide 15 with an arc-shaped loop.

A swing arm in its position of tilt α is configured on two sides, with reference to the axis of rotation 7 of the rolling wheel 6. The adjustable arm 5 it has, in this way, two sections 5a, 5b, of which one section it is foreseen in figure 2 to the right of the axis of rotation 7 and the other section in figure 2 to the left of the axis of rotation.

The right section 5b ends with one end. 5b '' at another pivotal support point 8, which allows movement of tilt of arm 5 in the α direction, but blocks a longitudinal sliding The pivotal support point 8 is coupled with a bearing support 9, whose height extension is h9 and has a support section and a mounting section. The mounting section can be mounted through two openings 9a, 9b in the front side of the swing, to fix the arm in the x direction.

The housing support section of bearing, in which the pivotal support point 8 is provided for  the swing arm 5, can also be prepared by a mounting opening 9c, so that the bearing support can join at various points firmly with the lateral H-beam.

By means of the bearing support, a non-slip mount on this stringer at a distance from the area of corner of the swinging F. From this fixed support point extend the adjustable arm 5 in the longitudinal direction (basically in the x direction) and can be varied by the point of support 8 in tilt assumption α. With his movement of tilting, does not slip due to the fixed mounting of the support bearing, but only its tilting position varies.

The rotating roller is provided for the purpose of longitudinal extension of arm 5, with a support point 7 to a distance from the first rotating support point 8 and the end 5a '' (left) of the second arm section 5a, from which the support point 7 also presents a distance.

By adjusting the tilting position of arm 5, which can occur in principle at one point discretionary of the arm, the distance of the rotating support 7 of the roller from the bottom edge of the stringer beam and, with that is, the rolling height of the swing F in its lateral adjustment in sense x. If various roller mechanisms are provided, they are performed various adjustments by tilting (various) arms 5.

An adjusted mounting height can once remain fixed, but can also be reset later if due to the manifestations of use of the swing seems necessary.

For tilt position adjustment α of the arm can serve the intended regulation mechanism in figure 2 in the final section 5a '' left free of the arm, which is basically oriented perpendicularly.

The regulation mechanism fits in the section free end of the swing arm 5, so that the force applied for adjustment it is optimized by the lever law with respect to height adjustment obtained in this way. Preferably, for this the first section 5a between the pivotal support point 7 and the point access control mechanism is set larger that the second section 5b, between both support points 7, 8. In a especially preferred embodiment, these arm sections They have a proportion of approx. 1: 2, so force is distributed and corresponding elevation.

The shown embodiment of the mechanism of regulation that acts vertically is explained, in addition to the figure 2, also in figure 4 in the front side view exterior of the vertical stringer. A square 1 with a section 1a longer and a shorter section 1b that basically runs from perpendicular shape is intended for mounting in a slot longitudinal longitudinal of the swing. Mounting openings corresponding are detached from figure 2 and 5, in state assembled this corresponds to the place of placement of the position represented in figure 4.

Near the short section 1b that runs horizontally a projection 2 is provided in the form of a pivot, which houses a head 3a of a screw mechanism 3 between the section Cut 1b and himself. The screw device 3, which presents the thread section 3b and head section 3a, is basically invariable in the sense of height and but remains subject to rotating form between pivot 2 and square section 1b short. This turning movement is assumed by the thread section 3b in a piece that assumes the vertical force, preferably as a piece of nut 4, which is arranged in the arm swingarm.

The arrangement of this nut piece 4 is provided for a profiled configuration of the swing arm, of so that two sections of the U profile are provided with a window 4a, which houses a section of nut 4, for example, a square nut The nut piece that assumes the force basically cannot move, or in any case, only slightly in the direction of rotation, but allows a swing with respect to the arm tilting 5, with respect to a central plane of this arm, which runs hypothetically through both support points 7, 8.

The loose housing of the nut piece in the described windows of a swing arm configured in a way profiling compensates for the rigid orientation of the regulation mechanism vertical from square 1 and screw mechanism 3 regarding the variation of the arm tilt position swingarm 5 generated by the rotation of the screw.

Despite a compensation function, the piece nut is still in a position to assume and transmit the vertical force (according to swinging weight F), adjust the tilt position α of the swing arm and ensure a smoothness in the regulation movement.

Figure 4 shows that the orientation vertical and runs in a sequence - seen from above - so that a clamping function 2, a screwing function 3a and of again a clamping function 1b are firmly fixed with respect to the swing, on the contrary, the adjustment movement exerted of this mode in the swing arm 5 produces a variation of the position in height y_ {1}. The distance y_ {1} is at the same time, the clearance between the bottom edge of the swing and the edge top of the frame section that opposes, in which way two lateral side cover the distance and allow an adjustment of so that a variation of the position in height y1 but no slack.

The adaptation of the square piece 1b cuts with flanks of two sides 1b 'and 1b' 'takes care of a stabilization  lateral within a planned vertical groove. Both projections 1b ' and 1b '' match the groove size.

A turn of the screw head 3a with, by example, an inner hexagon provided, distance slot 4 and the rocker arm 5 operated by it by means of the function of compensation with its previous section 5a of figure 4 of the Short section 1b of the square 1. The thread piece 3b visible in the Figure 4 moves up, while the arm is moves down, distancing its upper surface 5a 'from the angular piece 1b. This distance follows from figure 5 in status removed, where the thread section has also changed completely on the side above the nut 4. The arm swingarm 5 is shown at its maximum angular position α, in which the height dimension of the support point 7 has the distance y_ {2} from the rolling guide 15. Taking into account the points corresponding mounting of the other rotating support 8 and the bearing support 9 is obtained the clearance y_ {2 '} of the inner lower front surface of the horizontal stringer from the frame guide section, as depicted in figure 4 in section as a guide 15.

With a lower front surface or with a Swing arm 5 configured U-shaped profiled both edges front 5c in section 5a may be oblique, i.e. no they run parallel to the upper side 5a 'thereof arm section Thus, the height adjustment height y_ {2} can be extended, even before bumping the arm end 5a '' outside near the adjustment mechanism in the raceway guide 15. This final section 5a '' forms the end of the first section arm 5a, while the other end section 5b, the opposite end of the second arm section 5b ''. The latter is willing to tilting shape on the bearing support 9. Both sections endings cannot slide in the direction of thrust x.

The adjustment movement as such is very much clearer in a comparison of figures 3 and 5. Figure 3 form the zero position with the arm 5 oriented basically so parallel, while figure 5 shows the tilting position with the maximum tilt angle α and distance maximum possible y_ {2} 'of both horizontal stringers H, B. The effect of the adjustment direction from the verticals has been explained above and clearly emerges from the functional elements used for it, which have the same numbers of reference.

The longitudinal dimensions A, B described previously for the first and second arm section 5a, 5b is preferably selected in a 2: 1 ratio, can be varied this proportion, depending on the necessary adjustment height with respect to the force of adjustment that must be applied in the sense and in the regulation mechanism 3.1.

The location of roller 6 is located in the zero position with support point 7, so that a recess 21 in an armature 20 houses at least a part of the roller 6. Thus same, in an out-of-service state a part of the roller 6 can fit into this recess 21 according to figure 5. This embodiment specific can be modified according to the embodiments following.

The roller can be reduced, for example, by diameter d6 and at its support point 7, so that it can be varied towards the lower side of the arm so that it only protrudes towards down and the arm can maintain its zero position, without the upper end of roller 6 protrudes above the frame 20. In such an embodiment, it can be worked without a interruption 21 of the outer frame 20 of the stringer of the swinging

Interruption 21 can be avoided, but also expand An extension of the interruption in the x direction leads to that the bearing support 9 sinks, extending the displacement into the bearing support 9 at least partially on the stringer beam, so that its extension in height h9 is greater. This height extension is greater than the extension h5 of arm 5, at least, in section 5b '', which remains out of the armor.

To mount the bearing bracket 9 with a enlarged opening, can be sized so that it is mounted in a second armature 22 of the horizontal stringer that is higher in figure 3, fitting under (behind) the armor 20 Exterior. In this way, you get a better lateral stiffness in your mounted position.

These embodiments are not explained in drawings but with respect to the embodiments shown and They can easily imagine.

The combination of the embodiments previously described of the reduction of the roller diameter of rolling 6 to avoid interruption 21 and mounting position of the bearing support 9 displaced in the side member It can also be done in practice. Corresponds to a displacement of the opening 21 from the roller area of rolling 6 to an area of the bearing support 9.

The height adjustment obtained with an application of corresponding force as little as possible shows the difference between the gaps y_ {1} and y_ {2} 'in Figures 3 and 5.

In Figures 3 and 5 it follows in section that both armor 20, 22 mentioned are in a space stretched interior of a profile that can be seen in section, which has two horizontal wall sections 23a, 23, which are next to the armor.

The wall section 23 may be the basis of groove of a standardized profiled groove, on whose surface Inner armor 20 is placed as "outer armor." As armor can be used -as is also known in general- steel profiles or guides.

If the outer armor 20 continues, the support bearing 9 can be introduced through the wall 23 of the profile of swing and be arranged together or on the armor that find deeper (inner armor 22).

The special selection of a swing arm 5 shaped profiled must be deepened by the figure 2.

The first section of arm 5b longer and the shorter arm section 5b have in a 5d zone, in which they unite, an arc-shaped course for reinforcement in the area of support point 7 of this rolling wheel 6. From the end outside (relative to fixed support point 8) of the tread wheel Up to this point of support, the arm consists of only two swing sections, which include support 7 and the wheel rolling 6.

This arm section 5d can be manufactured from Especially simple, stable and easy way to mount on the Configured version profiled. Down, the profiled arm is configured in full length openly, being configured its front edges, at least, in a section of the first arm section 5a, obliquely, according to a inclination of the front edges 5c with respect to the cover of profile 5a ', which run parallel to each other.
