Description

The present invention relates to a carriage for a sliding leaf, in particular for a window or a door, with a support member on which at least two rollers are rotatably mounted, and a support member for fixing a wing on the carriage, wherein the support member relative to the support member parallel to Rotary axes of the rollers is movable, and a fitting for a sliding door.

The DE 10 2010 010 810 A1 discloses a fitting for a horizontally displaceable wing of a window or door, in which the wing is movably supported by lower and upper drives. In order to move the wing from a position locked to the frame to a sliding position, the wing can be lifted slightly from the frame, wherein the sliding movement of the wing is supported by springs. The disadvantage of this fitting is the high friction on the sliding surfaces of the drives.

In the DE 10 2014 220 837 B3 a carriage for parking a sliding leaf of a fixed frame is shown having a roller member with rollers and a wing receiving part for fixing the wing. Via a cam guide, the wing receiving part can be moved relative to the roller part, wherein the guide part is supported via a roller bearing with needle rollers. The carriage needed for the curve guide and the storage of the wing receiving part comparatively much space. In addition, there is the disadvantage that the wing receiving part and the roller part are rigidly held together, so that unevenness on the rail lead to a high point load on the guide surfaces, which is why a high friction can occur on the sliding surfaces. In addition, a high friction between the control pin of a drive rod and the backdrop of the roller part ensures a stiffness.

It is therefore an object of the present invention to provide a carriage for a sliding leaf in which a support member is easily movable relative to a support member and a compensation of unevenness of the guide can be compensated.

This object is achieved with a carriage with the features of claim 1.

According to the invention the carriage comprises a support member on which at least two rollers are rotatably mounted, and a support member for fixing a wing which is movable relative to the support member parallel to the axes of rotation of the rollers, wherein between the at least two rollers a bearing for rotatably supporting the Support member is provided relative to the support member. Due to the rotatable mounting, the support member can pivot relative to the support member, so that bumps on a guide rail, for example, by contamination, can be compensated. Due to the oscillating mounting of the support member on the support member a more uniform loading of the rollers is ensured, even if exposed to unevenness in a sliding movement of the carriage. Due to the oscillating bearing, in which an axis of rotation of the bearing is aligned parallel to the axis of rotation of the rollers, the influence of bumps can be compensated, without causing lateral forces or high point loads on the carriage.

Preferably, an axis is fixed to the support member which is slidably held on the bearing. Alternatively, the axle may also be fixed to the support member, and the bearing is slidably held on the support member. As a result of the bearing, a double function can be provided, on the one hand a displaceable guide in the axial direction and, in addition, a pivotable mounting about a bearing axis.

To fix the axis, two vertical webs may be provided on the support part, on which the axis is fixed. For this purpose, the axle can be stepped, so that movement of the axle in the axial direction relative to the support part is prevented, in particular if a radial surface of the steps bears against the webs as a stop surface.

For the oscillating mounting of the support member relative to the support member, the bearing is preferably arranged centrally between the at least two rollers. In this case, one or more rollers may be provided on each side of the bearing, but preferably only two rollers per carriage are used.

The bearing is preferably designed as a roller bearing, roll in the rolling elements along raceways. The bearing may for example be formed as a linear ball bearing, in which a plurality of arranged in a plurality of rows spherical rolling elements are provided so that a particularly smooth movement of the support member relative to the support member when parking from the closed position is possible in a flared position. In this case, at least three rolling elements in the direction of the axes of rotation of the rollers may be arranged side by side, preferably between four to 10 rolling elements in order to make a uniform load distribution to several rolling elements. The spherical rolling elements can thereby lead the support member relative to the support member both in a sliding movement in the horizontal direction, as well as in a pendulum movement of the support member relative to the support member. For a stable support of the spherical rolling elements, these can directly on a Axis abut. The axis can be made of a hardened steel to absorb the forces occurring with minimal deformation can. The spherical rolling elements may further be surrounded by a bearing ring which is inserted into a receptacle on the support member. It is of course also possible to hold the spherical rolling elements on an inner bearing ring which is inserted into a sleeve on the support member or support member.

The carriage according to the invention is used in particular in a fitting for a sliding door, in which a wing is held movable on a rail relative to a window frame. Distributed over the circumference of the wing can thereby be provided a plurality of lateral Abstellmittel to lift at an opening of the wing this first in the direction of the axes of rotation of the rollers of the frame and then to move over the rollers along the rail in the horizontal direction. Preferably, two or three carriages per wing are provided on an underside of the wing.

A fitting 1 for a sliding door includes two lower carriages 10 in which a wing can be supported, which is movable relative to a fixed frame. Every carriage 10 includes a support member 11 on which the wing is fixable, the carriage 10 over rollers 12 can be moved in the horizontal direction.

The fitting 1 further comprises first lateral shut-off means 2 that a housing 3 with a curve guide 4 in which a bolt 5 a control part 6 is movable. By a relative movement of the control part 6 to the housing 3 is about the lateral parking means 2 lifted the wing from a closed position of the frame or moved back to the closed position. In doing so, the control parts 6 be moved over a drive rod, via schematically represented Eckumlenkungen 7 with an upper parking means 8th is coupled. Also on the upper parking means 8th Can the wing in the axial direction of the rollers 12 be moved relative to the frame. On the first side parking means 2 opposite side are second lateral parking means 9 provided that an open cam 90 in which a bolt 91 a control 92 is guided. By a relative movement of the bolt 91 in the open cam 90 The wing can be turned off the frame before moving over the carriages 10 is moved. The design of the first lateral Abstellmittel 2 and the second lateral parking means 9 can be varied depending on the size and weight of the wing.

In 2A is a grand piano 20 in a closed position on a frame 50 held. Between wings 20 and frame 50 are elastic seals 51 provided, and in the closed position lies the wing 20 with a contact surface 22 at the seals 51 on, on the frame 50 are fixed. Alternatively or additionally, the seal 51 also on the wing 20 be fixed and at a contact surface on the frame 50 issue. In this closed position, the carriage can be 10 not yet relative to the frame 50 move as the seals 51 and optionally provide other fitting parts for a lock.

Shall the wing 20 be opened, the wing becomes 20 relative to the frame 50 parallel to the direction of the axes of rotation of the rollers 12 moved until the in 2 B shown position is reached, in which a contact surface 22 of the grand piano 20 spaced from the seal 51 is arranged so that no frictional or holding forces can act more. The movement of the grand piano 20 is achieved by a support member 11 relative to a support member 30 is moved because the support part 30 during this movement stationary over the rollers 12 on a rail 13 is supported. In the in 2 B shown off position, the wing 20 then along the rail 13 over the rollers 12 be moved. About the carriages 10 are the weights of the wing 20 supported, which can be over 150 kg, depending on the size. Especially when using insulating glass panes 21 With triple glazing, high weight loads must be provided by the carriages 10 be recorded.

In the 3A to 3C is the carriage 10 shown, the one upper support part 11 has, on which a plurality of openings 18 are provided, via which a frame of a wing 20 can be screwed. The support part 11 also has two vertical webs 14 and 15 on which an axle 44 is fixed. The axis 44 is by a bearing on a supporting part 30 led, on which two rollers 12 are provided. The distance between the vertical bars 14 and 15 is greater than the width of the support member 30 so that the support part 11 parallel to the direction of the axes of rotation the rollers 12 relative to the support member 30 can be moved.

At the footbridge 15 is a spring bar 17 provided on an end face of the supporting part 30 abuts and the support member 11 in a preassembled position on the support part 30 aligns.

In 4 is the carriage 10 shown in detail. The top-level support part 11 indicates the two vertical bars 14 and 15 a recording 16 in which a stepped end section 45 the axis 44 is insertable. This results in a radially and vertically aligned surface 46 on the axis 44 on an inside of the webs 14 or 15 on, and the axis 44 is characterized in the axial direction of the support member 11 fixed.

The supporting part 30 has a central bearing support 31 into which a camp 40 is insertable. On opposite sides of the bearing receiver 31 in the longitudinal direction of the rail 13 is on the support part 30 an implementation 33 for an axis 34 the rollers 12 intended. Every roller 12 is in an opening 38 on the support part 30 inserted, with the rollers 12 down from the supporting part 30 stand out and on the rail 13 are guided. The axis 34 can be stationary on the support part 30 be fixed, and the roller 12 is rotatable about a rolling bearing.

The warehouse 40 is designed as a linear ball bearing and includes a bearing sleeve 41 , on the inside of a plurality of spherical rolling elements 43 are arranged. The rolling elements 43 are at a Wälzkörperkä 42 held, being in the axial direction of the axis 44 several rolling elements 43 are provided side by side in a row. The number of rolling elements 43 in the axial direction, for example, be between 3 to 10. The rolling elements 43 stand inside over the Wälzkörperkä 42 out.

The warehouse 40 is used during assembly in the bearing holder 31 on the support part 30 inserted, preferably up to a stop, and then a cover 35 on the support part 30 mounted, the lateral projections 36 in the form of strips, in a groove 37 on the support part 30 are insertable. This is the camp 40 in the axial direction on the support part 30 fixed. The cover 35 has an inner opening 39 through which the axis 44 is performed. The cover 35 can be a stop for the Wälzkörperkä 42 of the camp 40 train to the movement of the axis 44 to limit in the axial direction.

If over the side parking 2 and 9 the wing 20 away from the frame 50 is to be moved, the support part 11 in a direction parallel to the axes of the rollers 12 together with the axle 44 moves, with the rolling elements 43 the axis 44 to contact. The Abstellbewegung can be, for example, 3 mm to 20 mm, and the spherical rolling elements 43 can in the axial direction in the bearing sleeve 41 roll.

Subsequently, the wing can 20 along the rail 13 be moved, with the rollers 12 on the rails 13 roll. If the rail 13 is uneven or dirty on the rail 13 is provided, the support member 30 relative to the support part 11 to perform a pendulum motion, the bearing 40 a rotation axis for a rotational movement of the support member 11 relative to the support member 30 formed. As a result, unevenness can be compensated and a uniform load distribution on the support member 11 be guaranteed.

To the high weight loads on the camp 40 Well, the axle can take 44 be made of a hard material, in particular a hardened steel. In addition, the rolling elements 43 and the bearing sleeve 41 be made of a hardened material. At the rolling elements 43 It is possible only a part of the rolling elements 43 that absorb the weight loads to produce from a very hard material, while the rolling elements 43 in an upper area on the bearing sleeve 41 may be made of a softer material. Alternatively or additionally, the distance between the rows of rolling elements 43 in the upper part of the bearing sleeve 41 be greater than in the lower area, in which the weight loads are absorbed.

To facilitate the opening movement, it is also possible to use the wing 20 to pretension with springs in the opening direction.
