SK8832Y1 - Sliding door or sidewall upper opening mechanism - Google Patents

Abstract

The upper mechanism for opening the sliding wall or side comprises a guide (1) fixedly connected to a shaft (5), which is located between rollers (2) mounted via a bearing (7) on the carrier (3), the carrier (3) being mounted on the sliding walls (4). By rotating the shaft (5), the sliding wall (4) is tilted in a circular path to the open position. After unfolding the sliding wall (4), the rollers (2) start rolling on the guide (1) by its subsequent displacement and at the end of the guide (1) the rollers (2) pass smoothly into the shape profile (6) of the second sliding wall. creates a guide for the complete extension of 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 sidewall or sliding wall to be unfolded and subsequently moved by means of several elements of the mechanism with a low friction or by using simple elements with a high shadow based mainly on 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 wing leaf slidably arranged between the guide rails, the solution not comprising elements for unfolding the wing part.

Chinese Utility Model CN207809393 (U), which was published 2018-09-04, discloses a sliding door system that includes a rail attached to a wagon body and a runner that is mounted on top of a sliding door. The runner is equipped with two pairs of bearings, which are oriented towards each other in two perpendicular 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 friction between segments, which also does not require any auxiliary elements. The upper mechanism consists of the lifting of a mainly circular cross-section located between the rollers mounted via 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.

Overview of figures in the drawings

In FIG. 1 is a sectional view of a wagon at the location of the upper mechanism. In FIG. 2 shows the upper mechanism in the closed state. In FIG. 3 shows the upper mechanism in the open state.

Examples of embodiments

The upper mechanism for opening the sliding wall or side is based on a combination of a simple tilting along the curve with maximum elimination of friction between the segments, which at the same time does not require any auxiliary elements. The upper mechanism for opening the sliding wall or side panel 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 profile 6 of the second sliding wall so that this profile 6 forms a guide 3 for the carrier to completely extend the sliding wall 4.
