Definitions

  • the invention relates to a carriage for the suspension of a part to be attached and along a travel path to be moved and a suspension system using such carriages.
  • a problem of such suspension systems is the readjustment of the sliding door leaf with respect to the suspension device.
  • a guide rail may sag over time so that a sliding door leaf on the floor may begin to drag. Then the sliding door has to be realigned with regard to its height adjustment.
  • carriages are fixedly connected to the sliding door leaf. Ie. they do not change their position with respect to the sliding door leaf.
  • a sliding door hanger with several guide rails on which rollers of the carriages roll, it may happen that the carriages are not guided precisely in or on the guide rails. Even one, seen horizontally in a direction transverse to a longitudinal extent of the guide rails, slight inclination of the carriage leads to an enormous lateral load on the suspension for the sliding door in the carriage and possibly also the guide rails.
  • the invention is therefore an object of the invention to provide a carriage and a suspension system for along at least one travel to moving parts, in which suspension the above problems are avoided or at least reduced.
  • the shaft can be swiveled on all sides by approx. 1 °.
  • the shaft protrudes at a distance from the carriage through a hole in a support web of the element holder. Below the support bar a screwed onto the external thread of the bolt nut is provided, which carries the element holder.
  • a respective roller carriage consists essentially of a hanger plate with two bearing openings for receiving bearing rings for supporting one axle with pairs on both sides of the hanger plate arranged rollers.
  • a hanger plate passing through the transverse bore is arranged in the middle between the pairs of rollers. It is penetrated by a central axis to the central longitudinal axis of the hanger plate and the transverse bore central bore, which has an oval cross section with extended in the longitudinal direction of the hanger plate, large oval axis.
  • a bearing pin is used, which has a central, cylindrical portion with the same length as a central portion of the transverse bore.
  • An axis of rotation of the at least one first roller extends transversely to the above-described downward direction and transversely to a tangent of the travel of the at least one part to be moved in a region of the at least one first roller.
  • the axis of rotation of the at least one first roller is thus formed by means of a radius or diameter line of the circle which intersects an axial center of this roller.
  • the aligned pair of rollers is thus arranged with respect to the working plane at a same height, so that it can roll either on one and the same guide rail or on two guide rails, which have a same height position with respect to the plane of action. This achieves further stabilization of the carriage.
  • the rollers and guide rails may each have a flat running surface.
  • the first and third rollers are preferably, seen in the direction of extension or extension direction of the axes of rotation, arranged on a front side of the carriage.
  • the second roller is arranged on a rear, the front side opposite and opposite side.
  • the corresponding guide rails are thus arranged extending on opposite sides of the carriage, which serves for the stability of the carriage. In addition, such guide rails are easy to integrate in a support profile.
  • the lower material thickness of the arms leads to a sprung mounting of the wheels mounted on the arms, so that any jerky movements or bumps in the guide rail or on the running surface of one or more of the rollers can be damped.
  • any inclinations of the moving part in the direction of the travel can be compensated within certain limits.
  • the first suspension part is accommodated on or in the middle section of the main body.
  • the upper end portion of the first suspension member according to the invention is stored freely rotatably mounted in a recess of the body.
  • the recess is formed complementary to an outer contour of the upper end portion of the first suspension part, with which the first suspension part comes into contact in the recess.
  • the recess consequently has a (partial) hollow spherical shape.
  • the upper end portion of the first suspension member is received freely rotatably mounted in a cavity of the body. Ie. the upper end portion is completely surrounded by the body.
  • the cavity is formed complementary to the outer contour of the upper end portion of the first suspension member at least in a region where the upper end portion of the first suspension member comes into contact.
  • the upper end portion is thus not necessarily with its entire surface on an inner surface of the cavity, which reduces friction between the cavity and the first suspension member and thus a possible increased wear.
  • the spring means is supported on a side facing away from the first suspension part by means of a support means.
  • Supporting means which is preferably a snap ring, is stationarily housed in the recess.
  • the main body of the carriage according to the invention preferably further comprises a through hole extending from a support surface of the recess or the cavity with respect to the first suspension member in a direction away from the first suspension member to the member to be moved, d. H. parallel to the above-described downward direction.
  • the first suspension part is inventively preferably set up for attachment of a second suspension part.
  • the second suspension part in turn is fastened to the part to be moved itself. It may alternatively be integrally formed with the part to be moved or, in the case of a frame sliding door leaf, for example.
  • the first suspension part preferably has a sleeve at a lower end section.
  • the sleeve is freely rotatably mounted on the lower end portion and protrudes with a predetermined length portion from the lower end portion.
  • This section preferably has an internally threaded portion.
  • the second suspension part has at its upper, the first suspension part end portion facing a complementary to the female threaded portion formed male threaded portion.
  • the first and second suspension members are attached to each other by screwing the sleeve onto the second suspension member.
  • the sleeve has a non-circular outer contour which, for example, has the shape of an external hexagon. It is thus possible to attach and adjust the suspension parts in the case of the second suspension part attached to or integrally formed with him to be moved part to each other and adjust. In the case of an external hexagon only a wrench is required. There the non-circular outer contour is accessible from the outside, a simple height readjustment of an already attached, moving part is possible.
  • the sleeve is preferably integrally formed with the lower end portion of the first suspension part. This has the advantage that no storage must be provided between the first suspension part and the sleeve, which can be subjected to enormous loads depending on the weight of the part to be moved. In the case, therefore, not the sleeve but the first suspension part itself is screwed to the second suspension part.
  • the sleeve is arranged with the female threaded portion on the second suspension member such that its portion of predetermined length from the second suspension member toward the first suspension part out protrudes, wherein the externally threaded portion described above is formed at the lower end portion of the first suspension member.
  • an additional section with a non-round outer contour is formed on the first suspension part between the outer threaded section and the upper end section, so that the first suspension part can be screwed to the second suspension part.
  • the main body of the carriage according to the invention is block-shaped and further preferably formed from a plastic. This makes it possible to produce the basic body in a particularly simple manner, for example by means of injection molding or extrusion.
  • a receptacle in the form of a bore or a passage opening is formed for each axis of rotation of the at least one roller in the main body.
  • the respective recording points in an inner space preferably has a projection which is formed in a plane transverse to a longitudinal extent of the respective pivot axis recording of an inner surface of the receptacle in its interior protruding.
  • the axis of rotation of the respective roller has a recess, which is formed substantially complementary to the projection, so that the projection of the respective axis of rotation at an insertion of the axis of rotation into the receptacle with the projection of the receptacle engages.
  • An inventive suspension system has at least a first, for example, upper guide rail.
  • it has at least one part to be moved along a travel path.
  • the at least one part to be moved is fixedly attached to or integrally formed with second suspension parts of at least two carriages described above.
  • the respective rollers of the carriage roll on the at least one first guide rail.
  • the suspension system according to the invention can have at least one second guide rail.
  • the carriages preferably each have at least two rollers in the case.
  • One of the at least two rollers of the respective carriage rolls on the at least one first guide rail, and the respective other roller of the respective carriage on the at least one second guide rail. treads the at least one first and second guide rails are formed facing each other.
  • the guide rails are arranged according to the invention in a support profile or integrally formed with it. This offers the advantage of supporting profile and guide rails form, for example, as a continuous casting, which allows a low-cost production.
  • the suspension system according to the invention also preferably has a profile in which the carriages are received stationary.
  • the profile is open on a side facing the at least one part to be moved and extends substantially parallel to a direction of travel of the part to be moved. Ie.
  • the profile is used to position the carriage to each other. In the case of the above-described circular travel, therefore, the profile preferably extends along a partial circle line of travel in the downward direction as described above.
  • profile and carriage together form a module that can be mounted as a whole.
  • the suspension system according to the invention can have at least one additional carriage. It also comprises a base body on which, analogously to the carriages described above, at least one roller is freely rotatably mounted, wherein an axis of rotation of the at least one roller extends transversely to a longitudinal extent of the additional carriage and transversely to the above-described downward direction.
  • This at least one additional carriage is also preferably arranged in the profile between the carriages described above, to which one and the same part to be moved is attached. The difference from the carriages described above is that this at least one additional carriage over no recording for a first suspension part has. It only serves to stabilize the profile. Especially with very wide doors a relatively long profile is required, which can bend or twist in operation and may begin to grind on, for example, a guide rail. This problem is avoided by means of the additional carriage in a simple manner.
  • the profile according to the invention has passage openings for inserting or pushing through the axes of rotation of rollers of the carriages.
  • the passage openings are arranged in alignment with the respective rotational axis recording of the corresponding carriage base body. thus extend in a direction parallel to a longitudinal extent of the axes of rotation.
  • the respective basic body is inserted or pushed into the profile towards the positions of the through openings.
  • the axes of rotation possibly with one-sided rollers, inserted from the outside through a respective passage opening of the profile into the respective rotary axis recording. Overall, this results in a very simple installation of the carriage.
  • the profile has a C-shaped cross-section.
  • free ends of the legs each have projections which are formed to extend toward each other. This creates a receiving space for the carriages, which allows a simple insertion of the main body of the carriage from one end face of the profile in the receiving space.
  • the linear drive can also be formed by means of a spindle or traction mechanism drive.
  • the part to be moved may be, for example, a sliding door leaf, a curved sliding door leaf, a partition wall module or a folding door leaf.
  • the sliding door panel 30 is fixed at its upper edge to sliding door panel suspension members 20.
  • the suspension parts 20 have at an upper end portion 21 each one upwards, ie in the y-direction in FIG. 1 extending male threaded portion 22 on.

  • a friction between the carriage suspension part 10 and the base body 101 is larger, which increases the force required to rotate the carriage suspension part 10 and thus makes it difficult to rotate. This is advantageous in that, for example, an abutment of a person against a sliding door leaf 30 only leads to a pivoting of the same from a certain force.
  • the upper portion 12 may also be flattened and preferably convex.
  • the convex shape is favorable, for example, when the upper end portion 12 in a center in FIG. 2 shown recess 110 is received and upwards, for example, to an inside of a support profile, little space.
  • a Auslenkungsbegrenzung also means of a above the carriage suspension part 10 arranged inner surface of the base 101 may be formed. In that case, one of the ends of the carriage suspending member 10, as seen in the horizontal plane xz, abuts the upper inner surface at a predetermined degree of rotation of the carriage suspending member 10, further rotating the carriage suspending member 10 can not.
  • the rollers 102 have a predetermined clearance on the axes of rotation 105 in a direction transverse to their effective direction ⁇ x, ie in the ⁇ z coordinate direction in the figures.
  • the rollers are thus additionally adapted to move in the direction transverse to their effective direction ⁇ x and thus compensate for any deformations of a respective guide rail 1, 2 or a support section 3.
  • This game can be realized in that a respective axis of rotation 105 has inner and outer stops. These stops can be realized in that the axis of rotation 105 has at a respective point circumferentially a circumferential groove, on each of which a snap ring is placed. This has the advantage that the rollers 102 can be replaced later.
  • at least the inner stop is integrally formed with the axis of rotation 105.
  • FIGS. 7A-7C show a preferably formed as a module rotor 40 of a linear motor, are mounted on the carriage 100 according to one of the embodiments described above.
  • the rotor 40 preferably has a row 41 of permanent magnets 41 a.
  • the magnets 41 a are fixed or mounted on a cross-sectionally substantially C-shaped profile 42.
  • the rotor may be formed by means of magnets 41 a, which are arranged on a stator, not shown, facing surface of the respective base body 101.
  • the attachment can be done for example by gluing.
  • the magnets 41 a are combined together to form a module.
  • the module can be formed, for example, by the individual magnets 41 a arranged in a row and potted by means of a potting compound.
  • the potting compound can also be used to attach the magnetic series 41 on the profile 42 or fastened.
  • a carriage 100 is inserted and inserted respectively right and left.
  • the carriages 100 themselves can be recognized by respective downward protruding sleeves 14.
  • the carriages 100 thus similarly have a base body 101 Figure 2C on.
  • FIG. 7B showing the rotor 40 from above in a plan view, it can be seen that the carriages 100 each preferably on both sides in each case two rollers 102, which are seen on the sides, in the ⁇ y coordinate direction, arranged offset from each other.
  • the profile 42 has at passages 43 at which rotational axis receptacles 106 of a respective carriage 100 are arranged.
  • the through-openings 43 as seen in the ⁇ z-coordinate direction, are aligned with the rotary axis receptacles 106.
  • the respective axis of rotation 105 is at one or both ends, on which or on which a roller 102 is mounted, from the respective carriage and the profile 42 to the outside, d. H. in + z or -z coordinate direction.
  • one purpose of the profile 42 is to position the carriages 100, 100 'in relation to each other. However, it is only necessary to attach one of the carriages 100, 100 'in a fixed manner to the profile. Therefore, according to a development of the invention, it is provided that only at least one passage opening 43 or a pair of passage openings 43 formed on opposite side walls of the profile 42 is designed to be complementary to the respective axis of rotation 105. At least one of the other through holes 43 is, as exemplified in FIG FIG. 8C shown, elongated hole-shaped.
  • the profile 42 is as below right in FIG. 7A shown enlarged, formed open at the bottom and has at lower ends of side walls facing projections 44 on.
  • a carriage 100, without rollers 102, in ⁇ x coordinate direction be inserted into the profile, and the carriage 100 is held by means of the profile 42.
  • a carriage 100 ' is arranged in the middle of the profile 42.
  • the rollers 102 of a respective carriage 100 are arranged such that, seen parallel to the plane of action xz in the ⁇ z coordinate direction, the outer two rollers 102 are arranged slightly higher than the two inner rollers 102nd Ie. the outer rollers 102 roll on two, arranged on both sides of the rotor 40 and not shown upper guide rails 1 from. The inner rollers 102 roll on two, also on both sides of the rotor 40 arranged and not shown lower guide rails 2 from.
  • the carriages 100 are thus held in position in guide rails 1, 2 due to the respective four rollers 102. This means that when attaching, for example, a sliding door leaf 30 to carriage 100 no unintentional tilting of the respective carriage in the guide rails 1, 2 can be done, which facilitates the attachment.
  • Figure 7D shows the profile 42 without attached carriage 100, 100 '.
  • FIGS. 7A-7D Even if in FIGS. 7A-7D a magnetic series 41 is shown, which extends over an entire length of the profile 42, it may be provided only in sections or extend over only a partial length of the profile 42. Since the stability of the profile 42 is particularly good, in particular in areas of the carriages 100, 100 ', the magnet row 41 can be designed so that the magnets 41 a occur only in these areas.
  • FIG 7E is a view of a linear motor suspension in a complete state shown. All parts of the linear motor are in a supporting profile 3 recorded.
  • the support profile preferably has two receiving spaces.
  • An upper receiving space serves to receive a stator 4 of the linear motor.
  • the stator 4 rests on a lower side on two projections, which are preferably formed by upper sides of upper guide rails 1.
  • the attachment or locking can be done for example by means of one or more screws 5.
  • the screw 5 is preferably screwed into an upper wall portion of the support section 3.
  • the screw 5 is supported on an underside of the upper wall portion of the support profile and presses the stator 4 against the tops of the projections on which the stator 4 is located.
  • the stator 4 is clamped in the support section 3 stationary and locked.
  • a sliding door panel 30 is attached to carriage hangers 10 of carriage 100 by means of sliding door suspension members 20.
  • the carriages 100, 100 ' are not accommodated in a single profile 42.
  • the suspension system has at least two profiles 42.
  • Figure 8A shows a profile 42, which is exemplified to receive a carriage 100.
  • the profile 42 has, in addition to the passage openings 43 for receiving rotational axes 105 of a carriage 100 at least on one end side in the direction of a longitudinal extension of the profile 42 from the profile 42 facing away latching projections in the form of locking lugs 45.
  • At the other end face can also latching noses 45 or, as in Figure 8A Shown, locking receptacles 46 for recording Locking lugs of another profile 42 may be formed.
  • the locking receptacles 46 are preferably as recesses or recesses or according to Figure 8A designed as through holes.
  • grooves 49 are formed in each case from one end face of the profile 42 to the respective latching receptacle 46 on an inner wall of the profile.
  • the grooves 49 preferably have a depth t which substantially corresponds to a thickness d of a lug portion 45a of a corresponding latching lug 45 of another profile 42.

  • all lug portions 45a and grooves 49 each have a same thickness d or depth t.
  • the detents 45 and locking receptacles 46 are arranged rotationally symmetrically on the end faces. Ie. the locking lugs 45 and locking receptacles 46 are arranged so that both end faces, viewed from the front, each have the same appearance. This makes it irrelevant with which end face the profile 42 is clipped or latched to another, not shown, profile 42, which simplifies the assembly.
  • An inner contour of the outer wall is formed substantially complementary to an outer contour of the inner wall, so that two profiles 42 can be plugged together with complementary end faces trained.
  • the outer wall of a profile 42 pushes on the inner wall of the other profile 42, and the locking lugs 45 of one profile 42 engage in the corresponding locking receptacles 46 of the other profile 42 a.
  • profiles 42 there are two types of profiles 42, one with the front side only protruding inner walls and one with the front side exclusively protruding outer walls.
