Description

End position retraction and end-position damping device for a sliding door

The invention relates to a Endlageneinzugs- and Endlage damping device for a sliding door according to the preamble of claim 1.

To close sliding doors, especially large-scale heavy sliding doors, relatively large shear forces are needed to accelerate the sliding door from a standstill. Once the heavy sliding door has been set in motion, in order to avoid a hard impact in the end position, it must again be braked with a correspondingly large counteracting force. From imprudence or negligence, these physical facts are often ignored and it is caused by the impact of the sliding door in the end position on the one hand noise and on the other hand it will spring back by its own elasticity from the end position, so that a gap and the door must be added later , This problem is known and there are damping and Endlagenschliesselemente on the market. A known device is described in EP 1426535. With a damping and retraction element comprising a fluid damper with a gas or liquid filling and a built-in spring in the same housing, such as a coil spring, on the one hand the impact is absorbed and damped and on the other hand by the tensioned during the previous opening of the sliding door spring the sliding door in the last centimeters of the displacement brought into the closed position. The known damping and retraction member or its common push rod is connected to a transmission member which transmits the movement of the push rod around the housing of the element at its rear side to a rotatably mounted on the end of the transmission member driving and control device. The rotatably mounted on an axis driver and control device is used to solve the connection between the sliding door and the damping and retraction device after a short distance to the end position and connect again when closing the door.

This known device solves the task asked of them, however, their structure is relatively expensive and complicated.

There are also known. Door damper known with which especially in elevators, the door is braked to the last degree before closing and pulled into the closed position. These known dampers in turn comprise a damping element in the form of a fluid damper and a spring element in the form of a helical spring, the common push rod is connected to the end of a pivot lever. The free end of the pivot lever is temporarily guided in a curved path in the context of an elevator door. Also, this device has been fulfilling its task for decades, but it has the disadvantage that the Abbrems- / Dämpfungsstrecke is very short and therefore it is only partially suitable for heavy sliding doors.

An object of the present invention is to provide a housable in a small space and inexpensive to produce Endlageeinzugs- and Endlädämpfungsvorrichtung for sliding doors with a sliding door suitable for long braking distance.

This object is achieved by a Endlageneinzugs- and Endlage damping device according to the features of claim 1.

Advantageous embodiments of the invention are described in the dependent claims.

With the use of a gas spring, the Endlakenämpfung and at the same time without using a metal spring, the sliding of the sliding door into the end position with a single element done, which is maintenance-free and available in various dimensions on the market.

Compared to the known damping and retraction element inventively fewer components are needed.

Reference to an illustrated embodiment, the invention is explained in detail. Show it

FIG. 3 shows a side view of the device in FIG. 1,

Figure 4 is an end view of the device in Figure 1 and

Figure 5 is a schematic perspective view of the device with the housing.

A Endlageeinzugs- and Endlage damping device, short device 1, comprises a mounting plate 3, which receives the mechanical elements of the device 1 and on which fastening means 5 for fixing the Device 1 are formed on the ceiling of a room or a cabinet 7. The only schematically indicated in Figures 1 and 2 cabinet 7 comprises a side wall 9 and a sliding door 11 which is displaceable in the direction of the arrows Y. The sliding door 11 is suspended by means of a drive (not shown) on a guide rail (not visible). The guide rail is fixed to the ceiling 13 of the cabinet 7 or the room. On the mounting plate 3, a gas spring 15 is held on one side with the mounting plate 3, preferably by means of a bolt 17. The end 21 of the protruding from the housing 19 of the gas spring 15 push rod 23 engages the knee 25 of a two-armed or v-shaped lever 27 at. The connection between the end 21 of the push rod 23 and the lever 27 via a bolt 29. The first lever arm 31 carries a guide member 32, in the example a roller whose axis is parallel to the axis of the bolt 29. On the second lever arm 33 is seated a guide roller 35, whose axis of rotation is also arranged parallel to the axis of the bolt 29. At the free end of the push rod 23, a slider 37 is preferably attached, which is guided longitudinally between two side guides 39. Preferably, the end 21 of the push rod 23 directly engages the slider 37 and the bolt 29 is mounted on the slider 37 (see Figs. 1 and 2). The longitudinal guide of the push rod 23 with the slider 37 serves to the gas spring 19 at its push rod end axially guided hold Zü. Of course, the slider 37 can be guided longitudinally in other ways, for example on a guide rod which is fixedly connected to the mounting plate 3 or in a dovetail groove, which is embedded in the mounting plate 3 (no Fig.).

The guide roller 35 on the second lever leg 33 lies in the first, rectilinear section 41 of a cam track 43 when the device 1 is in the end position (FIG. 1). At the first rectilinear portion 41 of the cam track 43 is followed by an arcuate second section 45 at. The second section 45 initially extends approximately at right angles or at slightly acute angles to the first section 41, in order subsequently to assume a purely acute angle to the first section 41. The mean radius R of the arcuate second portion 45 of the cam track 43 corresponds to the distance s of the axis of the pin 29 from the axis of the guide roller 35. These geometrical conditions allow the two-armed lever 27 to pivot when the guide roller 35 is at the end 40 of the first rectilinear portion 41 of the cam track 43 arrives and the first lever arm 31 is pushed in the direction of the arrow Y +. This pivoting movement takes place when the sliding door 11 from the closing or end position (Figure 1) in the direction of Arrow Y + pushed, that is opened. The triggering of the pivoting movement takes place by a driver 47, which is connected to the inside of the sliding door 11.

The driver 47 includes a closing leg 49, which is longer than the opening leg 51, which is opposite to the closing leg 49. The distance between the two legs 49,51 is greater, preferably slightly larger than the diameter of acting as a guide member roller 32 at the end of the first lever leg 31. The two legs 49 and 51 are mounted on a base plate 53, which in turn connects to the sliding door 11th manufactures.

In an advantageous embodiment of the invention (Figure 4), the opening leg 51 is mounted on a pivot plate 55 which is pivotally connected to the base plate 53. Between the pivot plate 55 and the base plate 53 may be a hinge 57, for example a hinge, be inserted and a spring 59 which holds the pivot plate 55 with the opening leg 51 in the horizontal position. However meets the guide member 32 and the role of the outside on the opening leg, because this occupies the position according to Figure 1, the tilting plate 55 tilts in the dot-dashed position in Figure 4, so that the guide member 32 on the opening leg! 51 in the Gap between the opening bracket! 51 and the SchliessSchenkel 49 can get.

The functioning of the device will be described in more detail below, starting from the closed position of the sliding door 11, as shown in FIG. The guide member 32, ie the roller on the end of the first lever arm 31, is between the closing leg 49 and the opening leg 51 of the driver 47. The push rod 23 of the gas spring 19 is extended, ie the gas spring 19 is not cocked, but it is located in a neutral position, so that by the push rod 23 no forces (neither tensile nor compressive forces) on the two-armed lever 27 load. When moving the sliding door 11 in the direction of the arrow Y + pushes the opening leg 51 of the driver 47 in the direction of the arrow Y + on the two-armed lever 27 and always leads this in the output angular position to the right until the guide roller 39, the end of the first straight section 41 of the cam track 43rd reached. At this point, since the end of the rectilinear portion 41 is reached, pivotal movement of the two-armed lever 27 starts counterclockwise, the guide roller 35 is guided in the arcuate second portion 45 of the cam track 43 upwards. At the same time, the guide member 32 shifts at right angles to the sliding door direction Y along the closing legs 49 and thus moves out of the sphere of influence of the opening leg 51 and is no longer moved by it in the direction of the arrow Y +. The two-armed lever 27 now remains in the position shown in Figure 2 and the sliding door 11 is moved without connection to the device 1 on.

Until the stop of the guide roller 35 at the end of the rectilinear portion 41, the push rod 23 and thus the piston in the gas spring 15 is displaced by the sliding door 11 to the right, thereby tensioning the gas spring 15. The energy now stored in the gas spring 15 is used in the subsequent closing of the sliding door 11, i. when moving in the direction of the arrow Y- to ensure that the sliding door 11 is held in the end position. The triggering of the stored in the gas spring 15 closing energy takes place through the closing leg 49 when it detects the guide member 32 during the manual displacement of the sliding door 11 in the direction Y- and the two-armed lever 27 leads out of its rest position clockwise and so a shift or the Extending the push rod 23 in the direction of the arrow Y- triggers. At the same time, however, the gas spring 15 acts as a damping element, since in the housing 19 also push rod side air must be displaced to the other side of the piston.
