CS198416B1 - Swinging sliding doors,especially for delivery trucks and passenger cars - Google Patents

Description

The subject of the invention is a swinging sliding door, in particular for vans and passenger cars, which, in the closed position, do not protrude from the body contour, but in the open position they are extended from the body contour. The doors are held in three places with one swivel and two fixed arms on them.

According to the prior art, swinging sliding doors are known which slide out of the body contour by means of a swinging arm, and wherein a guide arm is provided for guiding the door when moving along the body. In this case, the pivoting arm is fixed approximately in the middle of the vertical edge of the door, but for their further attachment it is still necessary to have a hinge device, for example a roller rolling on a rail located above the upper horizontal edge of the door. In these embodiments, however, an additional guide element is required so that the sliding door has an appropriate distance from the body surface when it is moved. For this purpose there are guide arms mounted on the inside of the door and guided in another rail located below the door opening. Such embodiments cause problems, for example, in small vans where the mudguards interfere, so that the lower guide rail reaches only part of the width of the door opening, with the result that the door cannot be fully opened and the entire door opening can be released.

In other embodiments, the door must first be pulled out of the door opening and thus out of the body contour before moving it.

Previously known sliding doors, in particular for automobiles, are complex and contain more elements, increasing maintenance, cleaning and adjustment requirements, and thus a higher failure rate with a reduced service life.

These drawbacks of the prior art devices eliminate the swinging sliding door according to the invention, which consists in that the door guide consists of a shaped rail and a roller pulley on its upper part, a ball pulley and a shaped rail in the lower part of the door in its central region. parts of a pulley mounted on a two-arm lever consisting of a swing arm and an articulated lever, articulated to the door, the roller rolling at the lower edge of the rail, which is located on the body contour and terminates with a locking cam, on which the two-arm lever is mounted.

The object of the invention is shown in the accompanying drawings, in which Figs. 1a, 1b, 1d, 1d show the guide of the upper and lower parts of the door and Figs. 2a, 2b, 2c, 3a, 3b of their guide in the region of their central part. locking in closed state

The retracting and locking device itself (Fig. 2) consists of a carriage 1 running on the rail 2 by means of a pulley 3. The rail 2 is fixed to the body contour in the central area of the door. The trolley 1 pivotally supports a two-arm lever consisting of an arm 4 carrying a pulley 5 at its end and a hinged lever 8 connected to the door by means of a hinge 6. The pulley 5 rolls at the lower edge of the rail 2 terminated by a locking cam 7 into its recess engages roller 5 with door 10 retracted.

The door guide 10 (FIG. 1) consists of a ball pulley 11 and a shaped rail 14 at their bottom and a cylindrical pulley 13 and a shaped rail 15 at their upper part.

SUBJECT

Pivotable sliding doors, in particular for vans and cars, in the closed position recessed into and out of the body contour, characterized in that they comprise a guide consisting of a shaped rail (15) on the upper part of the door (10) and a cylindrical pulleys (13), at the bottom of the door (10) made of spherical pulley (11) and shaped rail (14) and in the middle part of the pulley bracket at the bottom of the door ensures its good rolling even in curved parts of shaped rail 14 .

Inside the door 10 (FIG. 3), a fixed stop 16 is provided, in which the support plate 17 located on the projection of the articulated lever 8, which is also actuated by a spring 18, acts in the extended position of the door.

After the door has been pulled out of the vehicle outline, the pulley 5 rolls at the lower edge of the rail 2, preventing the door 10 and the vehicle wall from touching.

Claims (1)

OF THE INVENTION (5) located on a two-arm lever consisting of a swing arm (4) and an articulated lever (8) articulated to the door (10), which roller (5) rolls along the lower edge of the rail (2), The body contour is terminated by a cam lock (7) and at the same time forms a track for a pulley (3) supporting a carriage (1) on which the pivot arm (4) and the articulated lever (8) are supported.
