Description

Sliding door {SLIDING DOOR}

The present invention relates to a suspension structure for a door (sliding door) or a wall member, wherein the suspension structure allows the door or the wall member to be rearward from a closed position disposed in a door opening substantially parallel to the surrounding wall. A laterally offset and at least a portion may be displaced to an open position disposed behind the peripheral wall. In this case, the door or the wall member can be displaced from the open position to the closed position, on the one or more traveling rails disposed above the wall opening, via a moving carriage that is forward in the closing direction and a moving carriage that is rearward in the closing direction. Do.

Conventional sliding doors are laterally, from the open position in which the door member completely opens the door opening, through the two moving carriages running on a common running rail, to the closed position in which the door member closes the door opening. Displacement is possible. Due to this longitudinal movement only, the door member must be disposed on one side of the peripheral wall or door opening and closed on one side, or be embedded in the peripheral wall in a complicated structure. In each case, it is impossible to obtain a closed position in which the door is arranged in the same plane as the surrounding wall on at least one side. Sliding door structures of this type are problematic, for example with regard to sealing, and require complex structures, for example countersink seals, brush seals and the like.

As can be seen, for example, in the sphere of the door of a vehicle (train, bus), in their sliding door structure, it is possible to ensure the same flush position closed outwards during opening operation. The door is first offset laterally, ie at right angles to the plane of the door opening, by a special suspension structure and then moved laterally outward of the door opening. In the case of this type of structure, the suspension means are generally very complex designs but the problem of sealing easily occurs. This type of structure is disclosed in US Pat. No. 3,906,668, in which a complex lever structure is provided for an initial offset during opening operation, such that a rotatable displacement member about the vertical axis first displaces the door laterally from the door opening.

This structure can be combined with a mechanism that lowers the entire door to obtain a better sealing function. Structures of this type are for example disclosed in US Pat. No. 4,240,226.

It is therefore an object of the present invention, as a suspension structure for a door (sliding door) or a wall member, in which the door or the wall member is offset laterally from a closed position disposed in a door opening substantially parallel to the surrounding wall. And a suspension structure that displaces at least a portion to an open position disposed behind the peripheral wall. In this case, the door or the wall member can be displaced from the open position to the closed position, on the one or more traveling rails disposed above the wall opening, via a moving carriage that is forward in the closing direction and a moving carriage that is rearward in the closing direction. Do.

An optional structurally simple approach is possible when it is effectively necessary to offset the door or wall member laterally from the door opening, so that in two substantially straight running rails, the front moving carriage is mounted on the first running rail. (For example, via a pair of rollers rolling on a convex running rail to a concave running surface), the rearward moving carriage is mounted on the second traveling rail. In this case, the second travel rail is disposed substantially parallel to the peripheral wall and any range that is rearward in the closing direction, and the first travel rail is disposed forward in the closing direction. The first travel rail is at an angle with the second travel rail, for example in the range of 1 ° to 30 °. In other words, the first travel rail is arranged slightly obliquely. In addition, the rearward moving carriage preferably comprises a displacement member which substantially displaces the edge of the door or wall member located rearward in the closing direction preferentially only in the rearward direction when the opening operation is started. This displacement member ensures that the door is preferentially offset from the door opening.

Therefore, the gist of the present invention is to completely remove the curved running rail to provide a structure that can be easily applied to different clear widths of the door. Surprisingly, it is possible to provide a suspension structure by using two running rails arranged obliquely with respect to each other, which in principle provides an additional means of being laterally offset only at the edge of the door which is rearward in the closing direction. It was confirmed. This simplifies this structure considerably, thus reducing defects and making manufacturing costs more effective. In addition, stability is increased because the means for such an offset need not be arranged in the region of the foremost edge. In other words, in this situation, the door or wall member according to the prior art always preferentially is laterally offset from the door opening in both the area of the front edge and the area of the rear edge when initiating the opening operation, which is undesirable and not necessary at all. Instead, it is sufficient to ensure this offset at the rear only by an oblique straight running rail and to continuously guide the front edge behind the surrounding wall.

A first preferred embodiment of the invention is characterized in that the two running rails are arranged at the same height. Also preferably, the ends of the first travel rail which are forward in the closing direction are arranged at substantially the same lateral offset as the second travel rail (ie at the same distance behind the closed door) and which are rearward in the closing direction. The ends of the first travel rail are in particular arranged laterally with respect to the rear of the second travel rail and generally overlap slightly.

According to another preferred embodiment, in the closed position the door or wall member is arranged in substantially the same plane as the front side of the surrounding wall, and more preferably in the open position the suspension structure is such that the door or wall member is separated from the door opening. Allow it to be pushed out completely.

The above-mentioned substantial advantage of the suspension structure of the present invention is that, in principle, only the rearward moving carriage can comprise the displacement member.

The displacement member is preferably mounted under the second travel rail so that it can rotate about a vertical axis and rotate about a vertical axis when the door or wall member is laterally offset. In general, this rotation is in the range of 5 ° to 170 °, preferably in the range of 45 ° to 75 °. The vertical axis is preferably arranged aligned under the rearward moving carriage.

The suspension structure of the present invention has a driver, for example an electric motor driver. The driver is arranged in the area of the travel rail, and the driver can electrically displace the door or wall member. The drive is made, for example, through a shrinking member running substantially horizontally. This may be a toothed belt, an untoothed belt, a cabled member, or a chain, with a toothed belt being preferred. In the case of toothed belts, this toothed belt is driven by a pinion or a tooth disposed in the driver.

The displacement member preferably has a horizontal lever arm starting from the aforementioned axis and pointing rearward at all positions with respect to the door opening. A retracting member, preferably a toothed belt, is secured to the lever arm via a driver.

According to another embodiment of the suspension structure according to the invention, the displacement member has a horizontal pivot arm, on which the door or wall member is to be rotated, at least indirectly in the region of the rear edge and about the vertical axis. To be fixed. In this case, the pivot arm is angled with the lever arm, preferably in the range of 30 ° to 150 °, more preferably 60 ° to 120 ° or 90 °. In this case, the angle between the pivot arm and the lever arm is to be understood in particular as the angle between the vertical pivot point of the displacement member and the axis of the driver or guide roller.

In another preferred embodiment, the displacement member, pivot arm, and lever arm are designed as a single piece, and particularly preferably, the displacement member is designed in the form of substantially L-shaped sheet metal or L-shaped metal or plastic plate. The planes are arranged substantially horizontally.

In another preferred embodiment, a curved guide rail is provided, in which a guide roller disposed on the displacement member travels. In this case, the guide roller is disposed below the lever with respect to the axis, and when the opening operation is started by the rotation of the displacement member about the axis, the edge of the door or wall member lying rearward in the closing direction is first applied substantially to the rearward. Offset laterally only. In particular, the guide roller may be rotatably mounted about a vertical axis, and particularly preferably, the guide rail is U-shaped to which the guide roller is guided.

Guide rails of this type generally have a lateral section whose direction is preferably arranged substantially perpendicular to the door plane, a longitudinal section whose direction is substantially parallel to the wall, and the two sections (lateral section). And a curved section connecting the longitudinal sections). In this case, in the relative arrangement of the individual members and the available space, in the closed position of the door or wall member, the lateral section is arranged in front of the axis of the displacement member in the closing direction, preferably the longitudinal section is the second travel rail. The advantage of being placed behind the lateral direction of was confirmed.

In another preferred embodiment of the suspension structure, an area under the rearward moving carriage (generally above at least the full height of the door or wall member) is arranged with a vertical shaft on which the door or wall member is rotatably mounted. In the area of the rear edge, the door or wall member is arranged in alignment with an axis which is rotatably fixed, with the lower end connected to the floor guide. The connection to the floor guide allows the lateral offset of the rear edge in the floor area to proceed in coordination with the offset initiated at the upper edge via the displacement member, so that the door can be prevented from tilting.

For this purpose, the lower pivot arm is preferably arranged on the shaft or rigidly connected to the shaft in the region near the floor, the pivot arm is preferably oriented parallel to the upper pivot arm on the displacement member, and the lower guide roller (or a different guide) Means) are arranged on the lower pivot arm, the lower guide rollers being preferably guided in a straight floor guide, particularly preferably in the form of grooves embedded in the floor. In this case, the floor guide is generally arranged parallel below the second travel rail.

The door or wall member is generally rotatably fixed to the forward moving carriage. For example, it has been found to be structurally advantageous if the drive is arranged or fixed to the first travel rail.

An ideal flush structure is possible if the door or wall member is suspended in a curtain manner by door fixing means of the suspension structure, which applies especially to sliding doors that are entirely glass.

The door or wall member is preferably movable only in the horizontal direction and does not require a lowering mechanism.

By means of the displacement member, the suspension structure is preferably such that a lateral offset of the surrounding wall, for example at least 15 mm or 30 mm, preferably 50 mm to 500 mm, is possible compared to the suspension structure according to the prior art. do. Since it may include a door that must be offset behind a thick wall, a value larger than 200 mm may be considered and can be implemented in a simple manner by this structure.

In addition, the present invention relates to a door structure having a suspension structure as described above and having one or two doors. When two doors are provided, these doors may be arranged to move in opposite directions, The suspension structure is made in a mirror symmetrical manner. These doors are preferably sliding doors made entirely of glass.

Other preferred embodiments are described in the dependent claims.

Hereinafter, the present invention will be described in more detail through exemplary embodiments with reference to the accompanying drawings. These embodiments illustrate the functionality of the suspension means according to the invention and are not intended to limit the concept of the invention as defined in the claims.

1 a) is a vertical sectional view in the region of the suspension means viewed from the rear in the closing direction of the door 1 when the door 1 is closed. The door 1 is an all glass sliding door suspended by the door fixing means 6 without exerting any aesthetic effect on the front side (right) as much as possible. The door 1 is arranged in the same plane as the superstructure 3 and in the same plane as the surrounding fixed wall 29. The suspension means has a rearward carriage 19 which is displaceably mounted to the second travel rail 8 by a pair of travel rollers 11. In this case, the traveling rail 8 is designed as a profiled rail having a convex running surface, and the traveling roller 11 concave over the convex running surface. The traveling rail 8 is fixed to the superstructure 3. The running rail 8 is a straight, bending-free running rail disposed in parallel with the surrounding fixed wall 29.

The rearward carriage 19 has a rotational axis 18 which is preferably symmetrical with the two traveling rollers 11 below vertical. In the rotation shaft, the displacement member 15 is rotatably mounted about the rotation shaft 18 with respect to the rearward moving carriage 19. In the lever arm 31 facing rearward (left in FIG. 1 a), the displacement member has a driver 16, to which a toothed belt 21 (not shown) is fixed. The shaft 14, which extends over the entire height of the door 1, is arranged laterally offset relative to the axis of rotation 18 forward (right in a) of FIG. 1). This shaft 14 is held by the upper mounting means or the suspension means 27 in which the rear support member 5 is formed. As will be described later, the guide roller 17 having a function similar to that of the entire displacement member 15 is disposed coaxially with the shaft 14 on the displacement member 15. The guide rail 20 on which the guide roller 17 runs inside is similarly arranged in the upper region of the suspension means, and the function of the guide rail 20 will also be described later.

At the lower end, the shaft 14 is rotatably held in the lower mount 26, which likewise has a door fixing means 6. In addition, a lower pivot arm 25 having a lower guide roller 24 at an end remote from the shaft 14 is fixed to the lower end of the shaft 14. The lower guide roller 24 meshes with the floor guide 23 embedded in the floor 2. The lower guide roller 24 is disposed coaxially with the rotating shaft 18 below the vertical direction. The floor guide 23 is oriented downward and parallel to the second travel rail 8. The floor guide 23 is a straight guide rail. The overall structure in the floor area of the shaft 14 allows the complex movement of the displacement member 15 on the floor (to be described later) to be made in a controlled manner, and thus the lateral offset required at the start of the opening operation ( 1 a) to the left) proceeds downward in parallel with the release taking place at the top.

1 b shows a vertical cross section in the region of the front suspension means. The door 1 is held by the anterior support member 4 and the floor guide is omitted. However, it is also possible to arrange floor guides. The front support member 4 is fixed to the front moving carriage 9 so as to be easily rotatable through the front suspension means 10. The front moving carriage 9 also has a pair of running rollers 11 having a concave running surface. The pair of travel rollers 11 of the forward moving carriage 9 travel on the first travel rail 7 which is a travel rail which is not the same as the travel rail on which the rear moving carriage 19 is mounted. However, the first travel rail 7 is likewise a profiled rail with a convex running surface for the travel roller. The first travel rail 7 is fixed to the superstructure 3. Preferably, a driver or motor 12, and, if appropriate, a control box 28, is fixed to the first travel rail 7. The driver 12 has a pinion 13 for a toothed belt 21 (not shown) for opening movement of the door. The dimension shown to a) of FIG. 1 is a = 3000 mm and b = 190 mm, for example. That is, the suspension structure is suitable for a large door but does not occupy a large height in the suspension area disposed thereon.

Figure 2 is a horizontal sectional view of this type of structure, in which two sliding doors are shown closed at the same time. In particular, in this figure, it can be seen that the first travel rail 7 and the second travel rail 8 are arranged differently. The second running rail 8, which serves only for the mounting of the rear suspension means, is arranged in parallel behind the stationary peripheral wall 29. In contrast, the first travel rail 7 is arranged slightly obliquely to this, and the ends of the first travel rail 7 forward in the closing direction are arranged at the same distance behind the front plane formed by the fixed wall 29 and The rear end of the first travel rail 7 is arranged behind the second travel rail 8. This means that at the time of the opening operation, the front moving carriage 9 is continuously linearly offset backward. In addition, the position of the toothed belt 21 can be seen in this figure. The toothed belt 21 is guided between the pinion 13 and the deflection roller 22 and acts on the driver 16. The toothed belt 21 is arranged at a predetermined distance behind the second travel rail 8 and the guide rail 20.

In addition, in FIG. 2, the guide rail 20 is straight in the area | region which is rearward in the closing direction, and is bent in the foremost area | region. In this case, the bend is engaged with the foremost position of the rearward carriage.

In FIG. 3, the position of the door 1 shown on the right side of FIG. 2 can be easily seen by omitting the suspension means. In this case, six different positions are shown which in turn pass through when the door 1 is opened. In the closed position P1, the door 1 is arranged in the same plane as the peripheral wall 29 and is completely embedded in the door opening. In the initial state of opening, the door is preferentially offset rearward in the area of the suspension means to the position of P2 and not yet displaced laterally. After this lateral offset is completed and the rear edge is slightly released, the door 1 is displaced laterally (i.e. to the right in FIG. 2) and is fixed because the first guide rail 7 is arranged obliquely. The fully open state P3 in a position parallel to the wall 29 is taken. In the open state P3, the door 1 is completely arranged behind the wall 29 and thus fully opens the door opening.

FIG. 4 is a view showing a position similar to that in FIG. 3 with respect to the left side of the door shown in FIG. 2, but in this case a suspension means is shown. The main part shown by A is shown in FIG. Hereinafter, the complicated movement of the entire structure will be described with reference to FIGS. 4 and 5.

The displacement member 15 has a lever arm 31, the driver 16 is disposed at one end thereof, the other end is substantially formed by the rotation axis 18. Substantially, at right angles to the lever arm 31, the displacement member 15 has a pivot arm 32, at one end of which the rear support member 5 and the guide roller 17 are arranged, the other end likewise. It is substantially formed by the rotating shaft 18. The lever arm 31 generally has a length of 50 mm to 500 mm (the distance between the rotation axis 18 and the center point of the driver 16), and in particular in this embodiment a value of 105 mm was used. The pivot arm 32 generally has a length of 50 mm to 500 mm (the distance between the rotation axis 18 and the center point of the guide roller 17), in particular in this embodiment a value of 80 mm was used. The displacement member 15 is, for example, a sheet metal of 10 mm to 100 mm thickness.

The guide rail 20 has a longitudinal section 35 extending in parallel with the second travel rail 8. The guide rail is merged in the curved region 34 in the closing direction and is disposed at right angles with the plane of the wall 29 of the lateral region 33 in the end region. The guide roller 17 travels in the guide rail, and the guide roller 17, in the first state of the opening when actuated through the driver 16, the displacement member 15 preferentially performs pivot movement (offset). Only after doing the pushing motion.

In the closed position p1, the displacement member 15 is at the position which is inclined most to the right side of FIG. 5. In this state, when a force is applied to the left side with respect to the driver 16 through the toothed belt 21 of FIG. 5, the displacement member (due to the guide roller 17 guided in the guide rail in the lateral region 33) 15) preferentially performs the tilting motion counterclockwise. Thus, the displacement member 15 first moves from the closed position p1 to the intermediate position p2, during which the rotation about the rotation axis 18 takes place while the door 1 is laterally at the rear edge. Offset (upward in FIG. 5). The guide roller 17 travels past the curved area 34 of the guide rail 20 and continuously pushes against the lateral movement. As soon as the guide roller 17 passes through the curved area 34 of the guide rail 20, the counterclockwise rotational movement of the displacement member 15 ends (position p3) and the displacement by the subsequent pulling of the driver 16. The member 15 is displaced only laterally so that the door 1 is fixed to the displacement member 15.
