SK500112019U1 - Sliding door or sidewall upper opening mechanism - Google Patents

Abstract

The upper opening mechanism of the sliding wall or sidewall comprises a guide (1) fixed to the shaft (5), which is located between the rollers (2) mounted over the bearing (7) on the carrier (3), the carrier (3) being mounted on the wall (4). By rotating the shaft (5), the sliding wall (4) is swiveled to the open position along a circular path. After tilting the sliding wall (4), by its subsequent movement the rollers (2) begin to roll along the guide (1) and at the end of the guide (1) the rollers (2) pass smoothly into the profile profile (6) of the second sliding wall. provides a guide for completely extending the sliding wall (4).

Description

Technical field

The technical solution relates to the upper mechanism for opening the sliding wall or sidewall, in particular for railway wagons or truck superstructures.

Prior art

Current solutions allow the tilting and subsequent displacement of the sidewall or sliding wall by means of several elements of the mechanism with low friction or by using simple elements with high shade based mainly on the movement along a circular path or curve.

International patent application WO2010130537 (A1), published 2010-11-18, describes a sliding door system for rail vehicles, comprising a lower guide rail, an upper guide rail and at least one leaf wing slidably arranged between the guide rails, this solution not comprising elements for unfolding the wing part.

Chinese Utility Model CN207809393 (U), which was published in 2018-09-04, discloses a sliding door system that includes a rail attached to a wagon body and a runner that is attached to the top of a sliding door. The runner is equipped with two pairs of bearings, which are oriented towards each other in two rolling directions, where these bearings slide along the rail. The rail is bent on one side to pull the sliding door away from the side wall.

The essence of the technical solution

The essence of the technical solution lies in the solution of the upper mechanism of opening the sliding wall or side, which is based on a combination of simple tilting along the curve with maximum elimination of shading between segments, which at the same time does not require any auxiliary elements. The upper mechanism consists of the lifting of a mainly circular cross-section located between rollers mounted over a bearing on a carrier mounted on a sliding wall. By turning the shaft, the sliding wall tilts to the open position in a circular path. After unfolding the sliding wall and its subsequent displacement, the rollers will start to roll along the guide. At the end of the guide, the continuous rollers pass into the shape profile of the second sliding wall so that this profile forms a carrier guide for the complete extension of the sliding wall.

The advantage of the present solution is that it eliminates the friction between the tilting and tilting member to the maximum possible extent. Also, the vertical release of the sliding wall or sidewall allows a smooth transition even with manufacturing inaccuracies. Last but not least, the mechanism is a compact, simple design.

Examples of embodiments

The upper mechanism for opening the sliding wall or sidewall is based on a combination of simple tilting along the curve with maximum elimination of shading between segments, which at the same time does not require any auxiliary elements. The upper mechanism for opening the sliding wall or side wall comprises a guide 1, which is located between the rollers 2 and is fixed via a bearing 7 on the carrier 3, the carrier 3 being mounted on the sliding wall 4, where the guide 1 is connected to the shaft 5. along the circular path, the sliding wall 4 tilts to the open position. After the sliding wall 4 has been unfolded and subsequently moved, the rollers 2 begin to roll along the guide 1. At the end of the guide 1, the continuous rollers 2 pass into the shape profile 6 of the second sliding wall so that this shape profile 6 forms a guide 3 for guiding the sliding wall 4 completely.
