E12705632
The present invention in general is related to a method for moving an element from a first location to a second location, said movement includes a sliding movement. The invention is also related to a mechanism for performing the method of moving the element.
The element to be moved can be any type of element to be moved from an opening between adjacent elements or in a frame, etc. such as walls, to a location displaced from the opening, whereby the element is to slide to a position in parallel with the adjacent elements, etc. in the last part of the movement. The element can be a door of different kinds of furniture, parts of buildings, hatches, such as roof hatches, etc.
A problem for this kind of movement is to obtain a smooth movement operation, since the element must first be released from an adjacent element, before performing a sliding movement.
For example, sliding doors for furniture, p. ex. cabinets, lockers, etc., usually involve disadvantages in the sense of design options, necessary space and the ability to access items in the furniture. Therefore, it is desired to provide a better method for opening and closing, for example, a sliding door for cupboards. It is also desired to provide a mechanism that gives, for example, to the sliding doors a desired movement.
Document DE 3728998-A describes the features of the preamble of claim 1.
An object of the invention is at least to alleviate the problem indicated above. The present invention is based on the understanding that the provision of an appropriate articulated mechanism together with an extraction guide rail can give a smooth appearance when, for example, a sliding door of a closet is closed and a clean movement towards the state open and opposite to the closed state.
An important part of the present invention is that a smooth movement, including a sliding movement, can be achieved by first forcing an end of an element placed between adjacent elements that will rotate outward. Then the opposite end of the element is turned outward, so that the element will be in a location parallel to the location in the opening. In said parallel location, but not before reaching it, the element is allowed a sliding movement.
In the detailed description below, the element is a sliding door, but the person skilled in the art will realize that the invention can be used for many different types of elements, as indicated above. Although the sliding doors are often made of some kind of wood product, one skilled in the art realizes that the present invention can be used for elements of any material.
According to a first aspect, a method is provided for moving an element from a first location, within an opening, to a second location, outside and displaced from the opening. The movement includes a sliding movement and the total movement has several independent stages. In a first stage one end of the element is turned outward to a first extreme position. In a second stage, the other end of the element is turned out until the element is in a location parallel to the original location. At the end of said stage, locking means are released. In a third stage the element slides to the second location by the extension of an extraction guide rail, in which the element is received. The previous stages of the movement are repeated in reverse order to move the element from the second location to the first location within the opening.
According to a second aspect, a mechanism for performing the previous movement is provided. The mechanism has a housing. It also has an extraction guide rail, which has a first member thereof mounted on an element to move. The first member and the second member are slidably arranged with each other. The mechanism further comprises at least two lever arms. One end of the first lever arm is received at a pivot point in the extraction guide rail and the opposite end of said lever arm is received at a pivot point in the mechanism housing. The pivot point in the extraction guide rail is placed at a first end of the extraction guide rail.
For the element to be moved, there is usually a mechanism at two opposite ends of the element.
The extraction guide rail may have a third member slidably disposed between the first member and the second member to increase the sliding path of the extraction guide rail.
The mechanism may further comprise a lock-and-release mechanism arranged to lock the mutual displacement between the first member and the second member of the extraction guide rail when it is in a first location, and is arranged to release the lock when it is in A second location.

Figs. 32 to 35 illustrate the sequence of a fourth embodiment of a lock-and-release mechanism for a sliding door.
Fig. 1 illustrates a mechanism for a sliding door 1 according to a first embodiment that is not part of the invention. The mechanism comprises a housing 2 arranged to be mounted on a frame 3 of a piece of furniture that has a door 1. The piece of furniture can be, for example, a cabinet, cabinet, locker, bookcase with door, etc. The frame 3 can be made of wood, polymer, panel, metal, etc. and comprising side pieces, an upper part, a lower part and preferably also a rear part. Together with the door 1, the frame 3 preferably defines a space for storing clothes, mechanisms, books, etc. Preferably, the housing 2 of the mechanism is mounted on the upper part of the frame, and on the lower part an additional similar mechanism can be mounted such that the door can be given a stable assembly and a movement pattern, which will be understood from the following description.
The mechanism further comprises an extraction guide rail 4. The extraction guide rail 4 comprises a first member 5 and a second member 6 which are mutually sliding to implement the extraction function. Such extraction guide rails are known in the art of drawers, as for example described in the European patent application with publication number 2114206. As also indicated in the European patent application, the extraction guide rail can having a third member 7 slidably disposed between the first member 5 and the second member 6 to increase the sliding path of the extraction guide rail 4. The extraction guide rail 4 is of the so-called full expansion type that allows the door completely exit the access road for furniture items. In addition, as also described in this European patent application, the sliding can be improved by balls or rollers to reduce friction between the members. The extraction guide rail is also provided with damping elements to dampen the sliding movement at its extreme points.
The first member 5 of the extraction guide rail 4 is mounted on the door 1, while the second member 6 is mounted on lever arms of the mechanism, as described below.
The extraction guide rail 4 provides the advantage that the guide rail can be hidden behind the door, that is, hidden from the user, when the door is closed, which allows for better design options.
In the following description, the lever arms and pivot points, respectively, are assigned an identification as first, second, etc. to allow the lever arms and pivot points to be distinguished from each other, respectively. Identification should not be interpreted as defining a temporary or significant difference.
The mechanism further comprises a first lever arm 8 pivotally disposed between a first pivot point 9 of the housing 2 and a second pivot point 10 of the second member 6 of the extraction guide rail 4. The mechanism further comprises a second arm lever 11 pivotally disposed between a third pivot point 12 of the housing and a fourth pivot point 13 of a third lever arm 14 pivotally disposed at a fifth pivot point 15 of the second member 6 of the rail removal guide 4. The mechanism further comprises a fourth lever arm 16 pivotally disposed between a sixth pivot point 17 of the first lever arm 8 and a seventh pivot point 18 of the third lever arm 14. The housing arrangements 2, lever arms 8, 11, 14, 16 and the second member 6 can be seen as forming a kind of semiparallogram, in which the parallelism properties only apply to a first position, that is as illustrated in Figs. 1 to 3, and a second position, that is as illustrated in Fig. 4, while the second member 6 in between moves in a manner without parallelism, as described below with reference to Figs. 5 to 8.
In the first position or location, in which the door 1 is closed, the general direction of the second lever arm 11 is approximately parallel to a general direction of the extraction guide rail 4. The direction approximately parallel to the general direction of the rail of the extraction guide 4 of the general direction of the second lever arm 11 has an angle between 5 degrees and 15 degrees with the general direction of the extraction guide rail 4, in which a positive angle means that the third pivot point 12 is closer to the extraction guide rail 4 than the fourth pivot point 13. Preferably, the angle is between 0 degrees and 10 degrees, most preferably about 5 degrees. The approximately parallel direction provides the advantage that the edge of the door is allowed to exit without interfering with a nearby article, e.g. ex. a neighboring door mounted on the same plane as the sliding door, allowing for better design options. Here, the third lever arm 14 is essentially perpendicular to the extraction guide rail 4 to push the door out from the nearby article with the movement, which will be demonstrated later in greater detail, towards the second position.
or location The angle allows the critical end of the door, that is, the one that moves first when moving from the first to the second position, to turn outside without interfering with a nearby door or article. This is provided by a fourth pivot point 13 that moves essentially perpendicular to the general direction of the extraction guide rail during the first part of the movement from the first position to the second position.
In the second position, the extraction guide rail 4 moves parallel compared to when it is in the first position by pivoting the second lever arm 11 around the third pivot point 12, such that the first, third and fourth lever arm 8, 14, 16 ensure that the extraction guide rail 4 travels essentially parallel compared to when it is in the first position, and the door 1 can slide to an open position by extending the rail removal guide 4.
The parallel displacement places the door 1 in a position where it can be opened by the extraction guide rail without interference with a nearby article, e.g. ex. a neighboring door mounted on the same plane as the sliding door, allowing for better design options.
The arrangement of the pivot axes causes the mechanism to move straight between the first and second positions, that is, the door is maintained at the same altitude during the movement even if it moves according to the preferred pattern in the other two directions. To allow this, all pivot axes from the first to the seventh pivot point 9, 10,
12, 13, 15, 17, 18 are essentially parallel and mutually perpendicular to the general direction of the extraction guide rail 4 and perpendicular to the direction of parallel travel between the first position and the second position.
Sliding movement is only desirable when the mechanism is in the second position. Therefore, the mechanism may further comprise a lock-and-release mechanism 19 arranged to lock the mutual displacement between the first member 5 and the second member 6 of the extraction guide rail 4 when in the first position, and it has to release the lock when it is in the second position. The lock-and-release mechanism keeps the door in place until the sliding action is opened. In addition to facilitating handling and increasing the feeling of quality, the feature also prevents doors or other neighboring items mounted on the same plane as the closed door from being exposed to wear or damage from the sliding of the door to be opened. The lock-and-release mechanism 19, which is also illustrated enlarged in Fig. 3, may comprise a two-arm lever, pivotally arranged around an eighth pivot point 20 of the second member 6 of the guide rail of removal 4. A spring acts on the lever by urging it towards the position shown in Fig. 3. A first arm 21 of the two-arm lever is arranged to run into the third lever arm 14 when it is in the second position, such that the second arm 22 of the two-arm lever disengages from the lock when the two-arm lever pivots around the eighth pivot point 20, by the second arm 22 that is raised free of a pin 45 in the rail Extraction Guide 4. This lock-and-release mechanism configuration combines a mechanism that works automatically and is not complex.
The mechanism can be configured such that in the third lever arm 14, the fourth pivot point 13 is disposed between the fifth pivot point 15 and the seventh pivot point 18 considered in a general direction of the third lever arm 14. In addition, the configuration can be such that in the first lever arm 8, the sixth pivot point 17 is disposed between the first pivot point 9 and the second pivot point 10 considered in a general direction of the first lever arm 8. The pivot point configuration provides a particularly suitable movement of the door and the extraction guide rail from the first to the second position and vice versa.
The load on a lever arm can be considerable, depending on the weight of the door, and essentially in the second position and the extraction guide rail in its extended position. If all the load is to be taken at the pivot point in the housing, in the case of a heavy door the dimensions for this pivot should be considerable. In the light of a versatile mechanism for different door sizes and materials, the mechanism would not be economically viable for most of its applications. An approach has been found to solve this by providing a support at a distance from the pivot. The housing 2 may comprise, for example, an arc-shaped slit, which forms an arc with a constant radius with the pivot point, and the lever arm may comprise a guiding protuberance to allow the force to be approached and away from the housing 2 and approaching and moving away from the lever arm, arranged to engage with the arc-shaped slit. In addition to allowing a more economical dimension of the pivot, this solution allows limiting the displacement in a direction parallel to a pivot axis of the pivot point. Such an arrangement can be provided to either the first lever arm or the second lever arm, or both. Referring to the above exposure when the door slides out, the application of a protruding approach to the second lever arm is particularly advantageous when the mechanism is provided in an upper piece of the furniture frame, and the application of an approach With protrusion in the first lever arm is particularly advantageous when the mechanism is provided in a lower part of the furniture frame.
In this way, the housing 2 can further comprise a first arc-shaped slit 23, which forms an arc with a constant radius with the first pivot point 9, and the first lever arm 8 comprises a first guiding protrusion 24 arranged to engage with the first arc-shaped slit 23 to limit displacement in a direction parallel to a pivot axis of the first pivot point 9, and / or the housing 2 further comprises a second arc-shaped slit 25, which forms an arc with a constant radius with the third pivot point 12, and the second lever arm 11 comprises a second guiding protuberance 26 arranged to engage with the second arc-shaped slit 25 to limit displacement in a direction parallel to a pivot axis of the third pivot point 12, as can be seen in Figs. 2 and 4 for the respective first and second positions. The slits and bumps strengthen the construction and prevent the door from changing unintentionally in altitude or twisting as the load from the door changes during movement.
An alternative to a slit approach is to have a support surface with geometries similar to the arc-shaped slit, that is, provide a support at a distance from the pivot. In this way, the support surface is only allowed to take a force between the surface and the lever arm. However, if a mechanism is provided in the upper part and in the lower part of the furniture frame, and the support surface is provided in the first and second lever arm 8, 11, this solution will provide similar advantages to the approach. Extrusion
Figs. 5 to 10 illustrate the sequence of the opening movement, in which in Fig. 5 the door is closed and in Fig. 10 the door is completely open. The closing movement follows the opposite path, that is in the sequence of Fig. 10 to Fig. 5. Figs. 11 to 14 illustrate the sequence of the lock-and-release mechanism 19 in the opening sequence, where Fig. 14 illustrates the lock-and-release mechanism 19 that is in the release position, such that the door it can slide into its open state, as illustrated in Fig. 10. As shown during the opening movement, the third lever arm 14 will make contact with the first arm 21 of the two-arm lever and will tighten the arm 21 towards down. With the movement of the first arm 21, the two-arm lever will rotate at the eighth pivot point 20 raising the second arm 22 of the two-arm lever. When the second arm 22 has been lifted free of the pin 45, the door 1 can slide open. The two-arm lever is prestressed by means of a spring to a position in which the second arm 22 encounters a member of the extraction guide rail 4. Thus, when the locking-releasing mechanism is released the movement of the third lever arm 14 has to overcome the force of the spring.
Fig. 15 illustrates the assembled mechanism mounted on a furniture frame and on a door, respectively, with a cover plate mounted.
Additional embodiments of the sliding door mechanisms and additional embodiments of the lock-and-release mechanism will be described with reference to Figs. They show the different embodiments. The parts corresponding to the parts of the other embodiments are given the same reference numbers and are not normally treated extensively for each embodiment.
As indicated above, there is preferably a mechanism mounted at one end of an element, such as a sliding door, and an additional similar mechanism can be mounted at an opposite end, such that the element can be provided with a stable and stable assembly. a movement pattern below.
In the embodiment of Figs. 16-20, the mechanism according to the invention comprises a first lever arm 27 pivotally disposed between a first pivot point 28 of the housing 2 and a second pivot point 29 of the second member 6 of the extraction guide rail 4. The The mechanism further comprises a second lever arm 30 pivotally arranged with one end at a third pivot point 31 of the second member 6 of the extraction guide rail 4. The other end of the second lever arm 30 is disposable along of a groove 32 of the housing 2. A third lever arm 33 is pivotally disposed between a fourth pivot point 34 in the second lever arm 30 and a fifth pivot point 35 in the housing 2. The second pivot point 29 of the second member 6 of the extraction guide rail 4 and the first lever arm 27 are placed at one end of said second member 6. The third pivot point 31 of the second member 6 of the guide rail of extraction 2 and the second lever arm 30 are placed a short distance from the other end of said second member 6. The groove 32 of the housing 2 which receives one end of the second lever arm 30, has a first part 36 inclined forward from an internal position of the housing 2 and towards an end of the housing 2 in which the third lever arm 33 is placed. Said end of the housing 2 is the end at which one end of the sliding door 1 is given a First move out. The first inclined part 36 of the groove 32 is followed by a second part 37 which has a general extension perpendicular to the sliding door. Said second part 37 of the groove 32 has a slightly bent shape, whereby the end of the groove 32 is placed closer to the end of the housing 2 in which the third lever arm 33 is placed, than the area of the groove 32 that goes from the first part 36 to the second part 37. The second lever arm 30 is movable along the groove 32 by means of a guide wheel 38. The second lever arm 30 has a bent shape and the fifth pivot point 35 is placed inside the curve of the second lever arm 30.
At the opening of the sliding door 1 of this embodiment, one end of the sliding door 1 is pulled out, whereby the guide wheel 38 of the second lever arm 30, will go along the first part 36 of the groove 32. The third lever arm 33 will pivot outward when the second lever arm 30 goes along the groove 32. When the guide wheel 38 of the second lever arm 30 has reached the area where the groove 32 goes From the first part 36 to the second part 37, the first lever arm 27 will begin to rotate outward. The first lever arm 27 will rotate until it is approximately perpendicular to the sliding door 1.
When the first lever arm 27 has turned outwardly perpendicular to the sliding door 1, the guide wheel 38 of the second lever arm 30 has reached the end of the second part 37 of the groove 32. The third lever arm 33 will rotate outwardly until it is perpendicular to the sliding door 1. In the position where the first lever arm 27 and the third lever arm 33 are perpendicular to the sliding door 1, the sliding door 1 will slide open.
In the embodiment of Figs. 21-24, which is not part of the invention, the mechanism comprises a first lever arm 39 pivotally disposed between a first pivot point 40 of the housing 2 and a second pivot point 41 of the second member 6 of the guide rail of extraction 4. The mechanism further comprises a second lever arm 42 pivotally disposed between a third pivot point 43 of the second member 6 of the extraction guide rail 4 and a fourth pivot point 44 of the housing 2. The second point pivot 41 of the second member 6 of the extraction guide rail 4 and the first lever arm 39 are placed in a
end of said second member 6. The third pivot point 43 of the second member 6 of the extraction guide rail 2 and the second lever arm 42 are placed at a distance from the other end of said second member 6. The second lever arm 42 has a curved shape whereby the lower part of the second lever arm 42 will be directed forward in the open position.
For all embodiments it is common that the pivot point between a lever arm and the extraction guide is placed at one end of the extraction guide, while the pivot point of a lever arm is positioned at a distance from the other end of the removal guide.
In Figs. 25 to 28 a further embodiment of a lock-and-release mechanism is shown. A lever arm 46 will act on a locking arm 47 to release the sliding door 1 for sliding movement. The locking arm 47 is rotated around a pivot point 48 by means of the lever arm 46. The locking arm 47 is spring loaded to a locked position. The lever arm 46 has a edge 49 positioned at a distance from the locking arm 47 in the closed position. The locking arm 47 has a fastener 50 at one end, said fastener bumps into an edge 52 of an extension 51 of a member of the extraction guide rail 4 in the closed position. The edge 49 of the lever arm 46 will act on the locking arm 47 at the end of the locking arm 47 opposite the end of the fastener 50, with respect to the pivot point 48. Thus, the fastener 50 of the locking arm lock 47 will be lifted free of the edge 52 of the extension 51 of a member of the extraction guide rail 4 when the lock arm 47 is rotated by the movement of the lever arm 46. The rotational movement of the pivot arm 47, activated by the edge 49 of the lever arm 46, it is acting against the spring load of the locking arm 47. The fastener 50 rises free of the edge 52 in the opening position of the opening and closing mechanism for the sliding door.
In Figs. 29 to 31, a further embodiment of a lock-and-release mechanism is shown. A lever arm 53 is received at a pivot point 54 of the extraction guide rail 4. An end portion 55 of the lever arm 53 has a groove 57 to receive a pin 56 placed in a member of the extraction guide rail
4. The end part 55 is an integrated part of the lever arm 53 or an independent part fixed to the lever arm 53. During the opening movement, the lever arm 53 will rotate at the pivot point 54, whereby the part end 55 also rotates and there will be relative movement between pin 56 and groove 57 of end portion 55 of lever arm 53. The shape of groove 57 is such that pin 56 will be free of groove 57 in the opening position of the opening and closing mechanism for the sliding door 1. In this way, in said opening position, the sliding door 1 can slide opening.
In Figs. 32 to 35 an additional embodiment of a lock-and-release mechanism is still shown. A lever arm 58 is received at a pivot point 59 of the extraction guide rail 4. An end portion 60 of the lever arm 58 will act at one end of the locking pin 61. The locking pin 61 has a projected part 62 at the opposite end to the end of the locking pin 61 on which the lever arm 58 operates. The lock pin 61 is pressed against the lever arm 58 by means of a spring. The locking pin 61 can move in a guide groove 63 in the extraction guide rail 4. The locking pin 61 has a projected part 62 at the opposite end to the end at which the lever arm 58 operates. closed position, the projected part 62 of the locking pin 61 is received in a recess 64 in the guide groove 63 of the extraction guide rail 4. When the projected part 62 of the locking pin 61 is received in the groove recess of guide 63, it is difficult for two members of the extraction guide rail 4 to move together. During the opening movement, the lever arm 58 will rotate around the pivot point 59. The end part 60 of the lever arm 58 will then move towards the locking pin 61. When the end part 60 of the lever arm 58 begins to pressing on the locking pin 61, the projected part 62 of the locking pin 61 will be moved in the direction away from the recess 64. In the opening position, the projected part 62 has left the recess, whereby the two members of the lane of Removal guide 4 can move between them, so that sliding door 1 can slide to an open position.
The different embodiments of the lock-and-release mechanism can be used with any of the different embodiments of the opening and closing mechanism for the sliding door.
The invention has been described above with reference to a few embodiments. However, as one skilled in the art will appreciate, within the scope of the invention, as defined in the appended patent claims, other embodiments are also possible apart from those described above.
