Description

The invention relates to a guide device for a piece of furniture with at least two sliding doors that are in a closed position flush in the same plane, along the restrictive part of paragraph 1 of the claims, as well as to a sliding door and piece of furniture with a sliding door.

Similar guiding devices for sliding doors of cabinets with sliding doors are known, for example, from patent document DE 202009004802 U1. This document describes a guide device for a sliding door of a corresponding piece of furniture, comprising a carriage that can be moved horizontally parallel to the outer surface of the sliding door along the guide rail and which is provided with external and internal support arms holding the sliding door so that when it is opened, it first from one plane with another sliding door rotates in a parallel plane. Then the sliding door thus turned by means of the carriage moves parallel to the body of the corresponding piece of furniture at a certain distance from it and completely opens the piece of furniture.

In the case of the guide device described in the above document, the carriage has a roller rolling along the running profile. The disadvantage of this solution is that when moving in the closing direction there is a significant lateral force that counteracts the movement of the guide device and, therefore, the entire sliding door. As a result, the forces for moving the sliding door in the closing direction are significantly higher than the forces for moving the door in the opening direction.

The problem to which the invention is directed, is to improve the prior art guide device, sliding door and furniture with sliding doors in order to ensure equally uniform movement of the sliding door in the closing direction and in the opening direction.

The specified problem is solved in the guide device of the sliding door of a piece of furniture with the features of claim 1 of the invention, a sliding door with the features of clause 12 of the claims and a piece of furniture with the features of clause 13 of the claims.

In particular, the proposed guide device is characterized by the presence of a latch mounted on the carriage, with which the support arm can be locked in the opening position approximately perpendicular to the longitudinal axis of the guide rail.

Due to this, with a linear movement of the guide device, i.e. when the sliding doors are moved parallel to the housing in the direction of opening or closing, the support arm is fixed, and the release of the fixation and the possibility of rotation occur only with the start of the rotation. As a result, no additional force is required to move the guide device. The force required to move the guide device now depends only on rolling friction, and equally in the closing direction and in the opening direction.

Preferred embodiments of the invention are characterized in the dependent claims.

According to one preferred embodiment, a switching element is provided that is mounted on a profiled part with a curved track placed on the guide rail and which, at a certain position of the carriage, moves the latch from the lock position of the support arm to the unlocked position of rotation of the support arm.

According to a preferred embodiment of the invention, the latch has at least one spring element and is movably mounted on the carriage. In this case, the latch, in particular, is made in the form of a clamping part, which is installed with springing parallel to the axis of rotation of the bearing arm and with which the end part of the bearing arm can be clamped in the transverse position with the locking of the bearing arm. That is, the switching element can adjust the position of the latch.

In a preferred embodiment, the switching element is wedge-shaped and in the closed position of the carriage holds the latch in the unlocked position of the rotation of the support arm. As a result, during the rectilinear movement of the carriage parallel to the plane of the sliding door, the switching element pushes the clamping part down vertically, which allows the support arm to rotate freely. At the end of the rotation of the carrier arm in the opening direction, the switching element unlocks the clamping part, which, under the action of the force of the elastic element, goes into the locked position and clamps the carrier arm.

As an alternative to moving the latch vertically to clamp the support arm, you can use horizontal movement, such as rotation.

Preferably, the latch has a profile that is consistent with the profile of the end portion of the support arm, so that when the support arm is in the open position, the latch profile is adjacent to the profile of the end portion of the support arm. These profiles may, for example, have convex and concave shapes consistent with each other, or they may have rectilinear profiles.

The proposed sliding door is characterized in that it uses guiding devices of the above construction.

The proposed piece of furniture is characterized in that it uses sliding doors with guiding devices of the above construction.

Below is explained in detail an example embodiment of the invention with reference to the drawings, where:

figa-5c - various schematic images of the carriage in a position in which it is offset in the opening direction as much as necessary to unlock the latch;

figa-6c - various schematic images of the carriage after its further displacement in the opening direction with locked bearing arms.

Used in the description of the drawings, the terms "top", "bottom", "left", "right", "front", "back" and the like only refer to the corresponding exemplary image and the relative position of the guide device, the bearing arm, the latch item or other components. These terms should not be understood restrictively, that is, in different operating positions, in a mirror-symmetrical design, or in similar cases, they may vary depending on the relative position of the components.

1, reference numeral 1 relates generally to a piece of furniture with sliding doors 2, 3, which in their closed position are flush in the same plane and cover the piece of furniture 1 with sliding doors, for example, a closet with sliding doors. To open the item 1 of furniture, one of the sliding doors 2, 3 is first turned from its closed position, from the plane common to both doors 2, 3, outward into a parallel plane, then moved in front of the second door 2, 3.

On each of the sliding doors 2, 3 in the upper part of the door there is a carriage 4 with two load arms 10, 20, which can be moved in the guide profile of the guide rail 8, which runs across the entire width of the furniture item 1. In addition, in order to ensure a stable movement of the sliding doors 2, 3, a guide (not shown) is installed in the lower part of the door 2, 3 for guiding the carriage, which also has two support arms.

As shown in FIGS. 2-6, when the sliding door 2 is opened, the carrier arms 10, 20 of the guide device are rotated from a position in which they are adjacent to the guide rail 8, to a position in which they are rotated approximately 50- relative to the furniture item 1 90 °, which allows you to slide the sliding door 2 without touching the adjacent sliding door 3.

During movement in the opening and closing direction, the gap between the two doors 2, 3 remains unchanged, regardless of the rotation immediately at the beginning of the movement in the opening direction or immediately before returning to the closed position. The length of the supporting levers 10, 20 can be selected depending on whether a gap is required for the door handle, which can be installed on the front side of the sliding doors 2, 3, or whether the doors 2, 3 should move quite close to each other.

Schematic diagrams of various positions in FIGS. 2-6 illustrate the sequence of the individual stages of movement when one of the sliding doors 2, 3 moves in the opening direction. In this case, FIGS. 2a-6a in each case show a top view of one of the variants of the proposed guide device for the sliding door 2 of the furniture item 1 with sliding doors. Each of FIGS. 2b-6b is a detailed axonometric view from below of the first carriage part 5, and in FIGS. 2c-6c, the first carriage part 5 is shown in sectional side view, which clearly illustrates the locking of the support arm 10 by means of a latch 31 located on the carriage four.

As shown in FIGS. 2a-6a, the guide device comprises an upper carriage 4 with an external support arm 10 and an internal support arm 20, fixed at one end by fasteners 17, 22 on the first part 5 of the carriage and, accordingly, on the second part 6 of the carriage, two carriage parts 5, 6 are connected to each other by means of a connecting part 7, preferably of tubular shape. It is also possible to use the whole carriage 4.

At the ends of the supporting levers 10, 20, which are facing in the opposite direction from the carriage parts 5, 6, there are pivot bearings 11, 21 with door fittings 9, 27 installed on the door 2. In the mounted state, when viewed from above, the sliding door 2 together with the carriage 4 and the supporting arms 10, 20 forms a trapezoidal structure in which the sliding door 2 of the furniture item 1 and the carriage 4 are parallel sides, with the hinged connection of the carriage 4 with both supporting arms 10, 20 and the articulation of the supporting levers 10, 20 with the sliding door 2 allows you to change the ratio of the angles of the resulting trapezoidal structure.

On fig.2b-6b it is clearly seen that the first part 5 of the carriage and the second part 6 of the carriage consists mainly of a slide 13, 23, on each of which rollers 14 are installed on the sides of the longitudinal axis of the guide rail 8, on which the carriage 4 moves, 15 with a horizontal axis of rotation, which when moving the carriage 4 move in the guide rail 8. In addition, to ensure the constancy of the gap between the sliding doors 2, 3 and the housing of the corresponding piece of furniture 1 and to prevent the tilt of the sliding door 2, 3, the first slide 13 is installed control role ik 16 with a vertical axis of rotation, which also moves in the guide rail 8.

The second part 6 of the carriage also contains a slide 23 with rollers (not shown) with a horizontal axis of rotation moving in the guide rail 8, and a roller with a vertical axis of rotation to ensure a constant gap between the sliding door 2, 3 and the case of the corresponding piece of furniture 1. The second carriage part 6 also has a mounting metal plate 24, which is attached laterally to the slide 23 and on which a compressible element 25 is attached, connected to the support arm 20 so as to translate the support arm 20 from the open position of the support arm 20 to the closed position or vice versa. It is preferable to use a pneumatic spring as the compressible member 25, allowing the support arm 20 to be brought into two different positions due to the articulation between the support arm 20 and the head 26 of the compressible member 25. As shown in FIGS. 2a-6a, the head 26 of the compressible member 25 is pivotally mounted , with the possibility of rotation around a vertical axis, in the corner of that end of the bearing arm 20 that faces the slide 23, and when a certain angle is exceeded, it helps to close the sliding door 2, 3 by means of pressure on support arm 20.

In addition, as shown clearly in FIGS. 2b-6b, a latch 31 is installed on the underside of the first part 5 of the carriage 4, by which the support arm 10 can be locked in the opening position approximately perpendicular to the longitudinal axis of the guide rail 8.

To control the latch 31 on the profile part 30, which is fixedly mounted on the guide rail 8, a switching element 33 is installed, by means of which the latch 31 can be moved from the lock position of the support arm 10 to the unlocked position of the rotation of the carrier at a certain position of the carriage 4 or the first part 5 of the carriage lever 10.

A curved track 34 is made on the upper side of the profile part 30 facing the opposite side from the guide rail 8, in which, during opening and closing, the control means mounted on the lower side of the support arm 10 and representing a control roller 12 with a vertical axis 18 can move rotation by which the support arm 10 during the opening process can be rotated from the closing position, in which it is adjacent to the guide rail 8, in the opening position, almost perpendicular th longitudinal axis of the guide rail 8.

The latch 31 is designed to lock, in particular the clamping, of the bearing lever 10 in the opening position almost perpendicular to the longitudinal axis of the guide rail 8. To this end, it is preferable to make the latch 31 in the form of a clamping part mounted with springing parallel to the axis of rotation of the bearing lever 10, so as to enable clamping the end portion 19 of the support arm 10 in the locked position of the support arm 10 - as shown, in particular, in Fig.6b.

At the same time, as shown in Fig.2b-6b, in the preferred embodiment, the latch 31 is mounted on the carriage 4 with the possibility of displacement vertically with at least one elastic element 35, and the latch 31 in its position when it is adjacent to the lower side the slide 13, locks the support arm 10, and in the position when it is shifted down from the slide 13, unlocks the support arm 10.

In this embodiment, the latch 31 is pressed into the abutment position on the slide 13 using two elastic elements 35, each of which consists of a guide finger and a coil spring 36, covering the side surface of the guide finger and resting one end on the head of the guide finger, and the other end to the lower side of the latch 31. Each guide pin of the elastic member 35 passes through the vertical holes of the latch 31.

As shown in figs-6c, in the preferred embodiment, the switching element 33 to move the latch 31 from the lock position, in which it is adjacent to the slide 13 of the first part 5 of the carriage, in the unlocked position of the carrier arm 10, is made wedge-shaped as one with the profile part 30 and acts as the working part of the profile part 30, i.e. when the carriage 4, in particular its first part 5, is pushed to the profile part 30, the wedge-shaped switching element 33 is inserted between the lower side of the slide 13 of the first part 5 of the carriage and the upper side of the latch 31, as a result of which the latch 31 is pressed down from the slide 13 and unlocks the carrier the lever 10, in particular the end portion 19 of the support arm 10.

Below with reference to figures 2-6 is an example of a sequence of stages of movement when the guide device moves in the direction of opening the sliding door 2.

Figures 2a-2c show the initial position in which the sliding door 2 closes the corresponding piece of furniture 1, the control roller 12 of the support arm 10 is located in the curved track 34 of the profile part 30. The switching element 33 is located between the lower side of the first part 5 of the carriage and the latch 31 so that the support arm 10 is not engaged with the latch 31 and therefore can rotate freely.

Figures 3a-3c show the position of the guide device, in which the support arm 10, 20 is rotated from the abutment position to the guide rail 8 to a position almost perpendicular to the guide rail 8. This rotation is carried out by the direction of the control roller 12 in the curved track 34 of the profile part 30. As shown in FIG. 3c, in this position the carriage 4 has not yet linearly moved in the opening direction x, therefore, the switching element 33 is still in the unlocking position of the support arm 10 and, subsequently atelno, presses the latch 31 downward.

The position of the guide device from figa-4C corresponds to the beginning of the linear movement of the door 2 and, therefore, the carriage 4 upon reaching the sliding door 2 position parallel to the body of the item 1 furniture. As can be seen from figs, the carriage 4, in particular the slide 13 of the first part of the carriage, is slightly biased in the opening direction x, and this offset is so slight that the wedge-shaped switching element 33 is still between the latch 31 and the lower part of the slide, therefore , the latch 31 no still does not block the bearing arm 10.

As shown in FIGS. 5a-5c, only after further linear movement of the carriage 4 in the opening direction x, in which the carriage 4 is so out of engagement with the profile part 30 that the switching element 33 is out of the space between the lower side of the slide 13 and the latch 31 As a result of which the latch 31 comes into contact with the lower side of the slide, the latch 31 stops the support arm 10 in its temporary position approximately perpendicular to the guide rail 8.

Figures 6a-6c illustrate the position of the carriage 4, in which the first carriage part 5 or the slide 13 of the first carriage part 5 is completely out of the grip area of the shaped part 30 in the opening direction x, and the guiding device together with the locked support arm 10 continues to linearly move to x direction of opening.

When moving in the direction of closing the item 1 of furniture with sliding doors, the steps of moving the guide device proceed in the reverse order. If the sliding door 2 is open, the support arm 10 is still locked by the latch 31 in its current position. If the user moves the sliding door 2 in the direction to close it, the door 2 first moves linearly, parallel to the front side of the piece of furniture 1 with sliding doors. As soon as the carriage 4, in particular the first part 5 of the carriage, reaches the profile part 30, the switching element 33 again gradually enters between the latch 31 and the lower side of the slide 13, thereby unlocking the rotation of the support arm 10. Then, the control roller 12 of the support arm 10 enters a curved track 34 of the profile part 30, and the carriage 4 moves to the abutment protrusion 32 of the profile part and, thus, reaches its extreme position at which the sliding door 2 is again turned to its closed position.

The direction of movement of the latch 31 can be implemented differently than in the embodiment shown here. For example, to move between the locked position and the unlocked position instead of the vertical movement of the latch 31 on the spring elements 35 can carry out horizontal or vertical rotational or rotational movement.

There is the possibility of some modification, according to which the compressible element 25 will be replaced by another adjusting element capable of transmitting forces.

To lock the support arm 10 in the locked position, the latch 31 has a profile that is aligned with the profile 28 of the end portion 19 of the support arm 10, as, for example, is well shown in FIGS. 2b and 6b, and when the support arm 10 is in the open position, the lock profile 37 31 is adjacent to the profile 28 of the end portion 19 of the support arm 10. In this case, the profile 28 of the end portion 19 of the support arm 10 has a concave shape, and the profile 37 of the retainer 31, respectively, is convex in shape. Of course, on the contrary, profile 28 may have a convex, and profile 37, respectively, concave shape. In addition, the profiles 28, 37 of the end part 19 of the support arm 10 and the latch 31 can be made straightforward.
