Sliding panel system having panels sliding along at least one slide rail arrangement

Abstract

A sliding panel system whose sliding panel elements are aligned in a row next to each other when the sliding panel is closed and are positioned orthogonally in relation to the sliding panel when it is in its parked position. The individual sliding panel elements are guided on a first rail arrangement, a curved or bent rail section being adjacent to said slide rail in the transitional area leading to the parked position. The invention is characterized in that the slide rail has a curved or bent rail section in the transitional area leading to the parked position itself. When a point is switched immediately, said rail section opens up onto a parking rail running orthogonally or at an angle to the slide rail. The free end of the parking rail is configured so that it extends into the area of the sliding panel. At the same time, the last sliding panel element of the sliding panel is guided with its Front guide element (from the perspective of the closing direction) in the rail section and with its rear guide element exclusively in the parking rail, while all of the remaining sliding panel elements are guided in the rail section with both guide elements.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a sliding panel system with at least one sliding panel that is guided on at least one slide rail and may be located between two lateral peripheral boundaries, the sliding panel elements of which panel system, when the sliding panel is closed, or when the sliding panels are closed, may be aligned in a row next to one another, and in the parked position may run orthogonally or mutually perpendicular to the slide rail, whereby associated with each sliding panel element there may be two guide elements that are located at some distance from each other in the sliding direction, are guided in at least one slide rail, and are preferably realized in the form of trucks or rollers, and there may be an additional curved or angled rail segment that is connected to the guide rail, in the transition area to the parked position.

2. Background Information

Some sliding panel elements are frequently realized in the form of glass panel facades and are conventionally suspended from a ceiling rail that is located in the vicinity of the crossbar or of the ceiling, whereby, however, the slide rail can also be a floor rail. The individual sliding panel elements, which in the closed position are located aligned in a row next to one another, must be moved into a parking or stowage position when the sliding panel is opened, for which purpose the individual panel elements, which are normally moved by motor power, although they can also be moved manually, are separated in the vicinity of their adjacent connecting edges and are moved into the parked position. The location and configuration of the parked position depends on the space available in the specific application. The movement of the sliding panel elements into the parked position can be done relatively easily if the individual sliding panel elements can be moved laterally in the parking area so that they are practically perpendicular or at right angles to the opening or closing direction, i.e., at a right angle to the longitudinal direction of the rail, as described in European Patent No. EP 0 437 029 A1. In that publication, with reference to the final sliding panel element in the closing direction, a relatively simple connection to a wall that runs orthogonally to the rail, for example, is possible. In the transition area to the parked position, there is a rail segment that branches off from the rail with the interposition of a switch, so that when the sliding panel is opened, the respective leading guide element continues to follow the curve of the rail, while the respective trailing guide element of a moving panel element is deflected by means of a switch into the branching rail segment. It is apparent that when the moving panel elements are moved into the parked position described in European Patent Application No. EP 0 437 029 A1, the free passage area of the sliding panel on an open moving wall is restricted.

If—as described in German Patent Publication No. DE 40 15 870 A1—the parking area is located in a recess, the side walls of which run parallel to and are aligned with the longitudinal direction of the slide rail, a relatively good connection is possible between the last sliding panel element in the closing direction and the adjacent wall of the recess. However, this arrangement requires the existence or addition of a parking recess.

However, in sliding panel systems described in some publications, there are special problems with regard to the achievement of a tight connection of the final sliding panel element in the closing direction, if the connection must be made with a wall that runs orthogonally to the slide rail and the wall that borders the slide rail, and if, in the parked position, the individual sliding panel elements are also supposed to be in a position that runs essentially orthogonally or at an angle to the slide rail, without restricting the free passage width of the sliding panel. For this purpose, a curved or angled rail segment that branches off from the rail is necessary for the pivoting movement of the individual sliding panel elements by approximately 90 degrees or more from the aligned position when the sliding panel is closed into the parked position, in which curved or angled rail segment the individual sliding panel elements are guided with both trucks so that they can execute the pivoting movement by approximately 90 degrees.

One particular problem with this arrangement is the realization of the transition to the parked position so that on one hand, the pivoting movement can be reliably executed, and on the other hand so that there is a connection between the first sliding panel element in the opening direction and the adjacent wall.

On the curved guides described in some publications, that is, the curved or angled rail segments that branch off from the rail, it was not possible to bring the free closing edge of the first sliding panel element in the opening direction up to the wall to which it was to be connected, which meant that it was necessary to have an additional intermediate element at this point, e.g. in the form of a pivot-hung door or a shutter. This arrangement was found to have problems, on one hand on account of the extra effort and expense it entailed, and on the other hand, when the sliding panel is open, such intermediate elements interfere with unrestricted access between the walls that are adjacent to the sliding panel itself on both sides.

OBJECT OF THE INVENTION

One possible object of the present invention, on a sliding panel arrangement system of the type described above, is to propose a solution in which the transitional area to the parked position is realized so that there is no need for an additional intermediate segment between the rear closing edge of the final sliding panel element in the closing direction and the wall, i.e., the curved guide can be realized so that when the sliding panel is closed, the above-referenced sliding panel element can be in direct contact by means of its closing edge with the adjacent wall. An additional possible object of the present invention is not to restrict the free width of the passage through the sliding panel when the sliding panel elements are moved into the parked position.

SUMMARY OF THE INVENTION

The invention teaches that one possible object of the present invention described above may be accomplished by use of a sliding panel system configured to form partitions and also configured to permit at least one sliding panel arrangement to be guided by guide arrangements on at least one rail arrangement.

The invention teaches that the slide rail that guides the sliding panel elements may not continue into the vicinity of an adjacent wall, a parking recess, or similar space, but in the vicinity of the parked position, i.e., in front of the “railroad station”, has a curved or angled rail segment that emerges via a switch into a parking rail which is realized so that it runs orthogonally, perpendicularly, or at an angle to the rail. One essential feature of the invention is that the parking rail is extended beyond the vicinity of the switch junction toward the curve or path or profile of the sliding panel, i.e., the curve or path or profile of the sliding panel in the closed position, so that the last sliding panel element in the closing direction can be guided by means of its trailing guide element in the closing direction in this segment that is extended beyond the switch and forms the free end of the parking rail, while the leading guide element in the closing direction of the above-mentioned sliding panel element is forced into the angled or curved rail segment of the slide rail. In this manner, the final sliding panel element in the closing direction can be forcibly guided so that there is an essentially guaranteed tight connection between the above-mentioned sliding panel element and a peripheral boundary, which can be formed by a wall, for example. The realization of the guide elements or their roller guides is realized so that, when they interact with the above-mentioned switch, all the other sliding panel elements of the sliding panel run over the switch into the curved or angled rail segment of the slide rail.

In other words, in one possible embodiment of the present invention, the present invention teaches that the slide rail that guides the sliding panel elements may possibly not continue into the vicinity of an adjacent wall, a parking recess, or similar space, but in the vicinity of the parked position, i.e., in front of the “railroad station”, such slide rail may have a curved or angled rail segment that emerges via a switch or intersection into a parking rail, which parking rail is realized so that it runs orthogonally, perpendicularly, or at an angle to at least the slide rail or slide rail arrangement. One essential feature of the invention may be that the parking rail is extended beyond the vicinity of the switch unction toward the curve or path or profile of the sliding panel, i.e., the curve or path or profile of the sliding panel in the closed position, so that the last sliding panel element in the closing direction can be guided by means of at least one of its guide elements or arrangements in the closing direction in this segment that is extended beyond the switch and forms the free end of the parking rail, while the leading guide element in the closing direction of the above-mentioned sliding panel element is forced into the angled or curved rail segment of the slide rail. In this manner, the final sliding panel element in the closing direction can be forcibly guided so that there is an essentially tight connection, contact, or adjacency between the above-mentioned sliding panel element and a peripheral boundary, which peripheral boundary can be formed by, for example, a wall, another sliding panel element, a barrier, or a solid surface. The guide elements or their roller guides may be realized so that, when they interact with the above-mentioned switch or intersection, all the other sliding panel elements of the sliding panel may run over the switch into the curved or angled rail segment of the slide rail.

The solution taught by the present invention therefore does not require the presence of an additional intermediate piece (such as a pivot-hung door panel, shutter, etc.), so that when the sliding panel system is open, i.e., when the sliding panel elements are in the parked position, there is an absolutely unrestricted passage between the walls that border the sliding panel.

In other words, in one possible embodiment of the present invention, the present invention may not require an additional intermediate piece (such as, for example, a pivot-hung door panel or shutter), so that when the sliding panel elements are open, i.e., when the sliding panel elements are in the parked position, there may be an essentially unrestricted passage between the walls bordering the sliding panel system.

In other words, in another possible embodiment of the invention, when sliding panel elements have been moved into the parking rail, persons may be able to move freely within the rooms formed by the sliding panel system—that is, without encountering, for example, a recess, a pivot-hung door panel, a shutter, a protruding object, or any obstacles to human movement other than walls or peripheral boundaries and the components of the sliding panel system, including, for example, curved rail segments, if used, the guide or slide rail, the parking rail, the end or extension of the parking rail, and the sliding panel elements. Thus such a sliding panel system provides essentially increased efficiency, simplicity, economy of installation, compactness, and safety.

For reasons of space availability, and in particular on sliding panels with an extraordinarily large passage width, it may be appropriate to locate the above-mentioned parking rail not in the vicinity of a side wall, for example, a peripheral boundary formed by a wall, but, for example, in the vicinity of an existing wall that runs between the peripheral boundaries themselves, approximately orthogonally to the sliding panel. In this case, the present invention teaches that it may be appropriate to provide sliding panel segments on both sides of the free end of the parking rail that are each guided so that they run into the vicinity of the closed sliding panel, and to associate with each sliding panel segment a rail segment of the slide rail in the transitional area to the parked position that is angled toward the parked position and emerges with the interposition of a switch into the parking rail.

The present invention also teaches that in one possible embodiment of the present invention, the arrangement can be advantageously configured so that one of the two final sliding panel elements in the closing direction is guided with its trailing guide element in the closing direction exclusively in the parking rail and its leading guide element in the associated rail segment, while the neighboring final sliding panel element in the closing direction is guided with both guide elements in the associated rail segment. The result is a tight connection between the last two sliding panel elements.

In other words, the present invention may also teach that in one possible embodiment of the present invention, the sliding panel system can be advantageously configured so that one of the two final sliding panel elements in the closing direction may be guided with its trailing guide element in the closing direction exclusively in the parking rail and with its leading guide element in the associated rail segment, while the neighboring final sliding panel element in the closing direction may be guided with both guide elements in at least one or at least two of the other rail arrangements. The result may be an essentially tight connection, contact, or adjacency between the last two sliding panel elements.

In an additional possible configuration of the present invention, the parking rail itself can form the parking area if it is realized so that it is sufficiently long. However, the parking rail can also be used as a short feeder rail to deliver the individual sliding panel elements into a parking position that can be configured in any desired manner. The parking rail is preferably oriented at an angle of between approximately 90 degrees and approximately 135 degrees with respect to the slide rail. In one possible embodiment of the present invention, it may be essential for the present invention that the free end of the parking rail is guided into the vicinity of the closed sliding panel far enough so that a connection between the final sliding panel element in the closing direction and the preceding sliding panel element is possible.

In one possible embodiment of the present invention, at least one sliding panel or sliding panel arrangement in the parking rail may be moved into a closed, parked, or stationary position so that at least one sliding panel or sliding panel arrangement may establish a tight connection, contact, or immediate adjacency with another sliding panel element or other peripheral boundary, wall, barrier, or solid surface on at least one side of the parking rail or parking rail extension.

In another possible embodiment of the present invention, at least one of the curved or angled rail segments may be disposed at a substantial angle to the other rail arrangements and may form switches, shunts, points, deflections, or intersections with other rail arrangements to facilitate the essentially smooth or easy travel or movement of sliding panel arrangements in the rail arrangements in such a way as to enable a person skilled in the art to easily determine such configurations and arrangements with essentially minimum experimentation or without undue experimentation.

The above discussed embodiments of the present invention will be described further hereinbelow with reference to the accompanying figures. When the word “invention” is used in this specification, the word “invention” includes “inventions”, that is, the plural of “invention”. By stating “invention”, the Applicants do not in any way admit that the present application does not include more than one patentably and non-obviously distinct invention, and Applicants maintain that the present application may include more than one patentably and non-obviously distinct invention.

DESCRIPTION OF THE PREFERRED EMBODIMENT

In FIG. 1 , the sliding panel, which is designated 1 in general, is formed from one sliding panel segment 3 and two sliding panel segments 4 . It goes without saying that the number of sliding panel segments 4 can be any higher number. The sliding panel segments 3 and 4 are guided in a slide rail that is designated 2 , which does not extend into the vicinity of a free end 8 of a parking rail 7 but is bent at an angle by means of the rail segment 5 . The rail segment 5 emerges via a switch 13 into the parking rail 7 .

In FIG. 1 , the parking rail 7 runs orthogonally to the rail 2 , while in FIG. 2 , the parking rail 7 is bent at an angle of approximately 135 degrees with respect to the rail 2 .

FIG. 3 shows the individual phases of movement of the last sliding panel element 3 in the closing direction (Arrow X) during the closing of the sliding panel 1 . It is thereby assumed that the sliding panel element 4 with its two guide elements 12 (only one guide element 12 is shown) has first traveled through the parking rail 7 , then traveled through the corresponding deflection in the switch 13 into the rail segment 5 , and then entered the rail slide 2 . The final sliding panel element 3 in the closing direction is also first guided with its two guide elements 10 (which guide element 10 is shown in FIG. 4 ) and 11 in the parking rail 7 , whereby when it leaves the parking rail 7 , the leading guide element 10 (as shown in FIG. 4 ) in the closing direction is deflected by the switch 13 into the rail segment 5 , while the trailing guide element 11 in the closing direction travels through the switch 13 toward the free end 8 of the guide rail 7 . It is apparent that a tight connection with the peripheral boundary 9 , which in this case is formed by a wall, may thereby be possible.

In the exemplary embodiment illustrated in FIG. 4 , the parking rail 7 is located at some distance from the peripheral boundary 9 , so that on both sides of the parking rail 7 with reference to the sliding panel 1 there are rail segments 15 , 16 . The rail segment 15 in the exemplary embodiment is formed by a single sliding panel element which, when the rest of the wall is closed, for example, can represent a pivoting door that can be opened separately and moved into the parking position, as is desirable, for example, in passenger lounges if the public is to be permitted access to an automatic teller machine, for example, or to a similar device. FIG. 4 shows that the slide rails 2 that are located on both sides of the parking rail have rail segments 5 and 6 that are bent at an angle, whereby the rail segment 5 emerges via the switch 13 described above and the rail segment 6 may emerge via an additional switch 14 into the parking rail 7 .

Starting from the assumption that all of the sliding panel elements 3 , 4 are in the parked position, to close the sliding panel 1 , first the sliding panel elements 4 may be moved in the closing direction Y into their closed position, whereby all of the sliding panel elements 4 may pass with their leading and trailing guide elements 12 in the closing directions first through the parking rail 7 and then via the switch 14 , and then travel through the rail segment 6 and enter the associated rail 2 , so that they assume the position illustrated in FIG. 4 .

Then the sliding panel element 3 (or the additional sliding panel element, not shown, that precedes this sliding panel element 3 ) is moved out of the parked position, whereby the sliding panel element 3 is likewise guided in the closing direction X with its leading guide element 10 and its trailing guide element 11 first in the parking rail 7 . As the closing operation proceeds, the leading guide element 10 in the closing direction is deflected via the switch 13 into the rail segment 5 while—as described with reference to FIG. 3 —the trailing guide element passes through the switch 13 and enters the vicinity of the free end 8 of the parking rail 7 , thereby resulting in the closed position of the sliding panel illustrated in FIG. 4 . It is apparent that by means of the sliding panel element 3 , tight connections to both the peripheral boundary 9 and to the adjacent sliding panel element 4 may be possible.

FIG. 5 is a block diagram showing the connection between a control system 17 to control the sliding panel system 19 , a drive system 18 to drive the sliding panel system 19 , and the sliding panel system 19 .

One feature of the invention resides broadly in the sliding panel that is guided on at least one slide rail and is located between two lateral peripheral boundaries, the sliding panel elements of which sliding panel, when the sliding panel is closed, are oriented aligned in a row next to one another, and in the parked position run orthogonally to the slide rail, whereby associated with each sliding panel element there are two guide elements that are located at some distance From each other in the sliding direction, are guided in at least one slide rail and are preferably realized in the form of trucks, and there is an additional curved or angled rail segment that is connected to the guide rail, in the transition area to the parked position, characterized by the fact that the slide rail 2 in the transition area to the parked position, has a rail segment 5 , 6 that is curved or angled toward the parked position and emerges into a parking rail 7 that runs orthogonally or at any desired angle to the slide rail 2 , whereby there is a switch 13 , 14 between the rail segment 5 , 6 and the parking rail 7 , and that one free end 8 of the parking rail 7 is guided so that it runs into the vicinity of the closed sliding panel 1 , and that the last sliding panel element 3 of the sliding panel 1 in the closing direction Arrow X is guided by means of its leading guide element 10 in the closing direction Arrow X in the rail segment 5 and by means of its trailing guide element 11 exclusively in the parking rail 7 , while all the other sliding panel elements 4 are guided by means of both guide elements 12 in the rail segment 5 , 6 .
