Description

[Detailed description of the invention] This invention is a folded door panel in which each double-walled door plate is connected to each other by several connecting members surrounding two vertical pivot axes within the connecting members. Regarding engineered sliding doors.

The present invention is applied to a folding sliding door having two or more folding door panels for factory halls, large garages, etc.

Recently, energy shortages have been attracting more and more attention, and as energy costs have become higher and higher, seals at the joints between the door plates and the pivoting parts of folded sliding doors have become a problem.

Although the heat insulation of double-walled folding door panels has been improved to a satisfactory degree, there is still room for improvement regarding the gaps in the connecting parts between them. .

This elongated gap cannot be sealed satisfactorily by the folding of various conventional folding S-sliding door construction styles, and therefore, especially when there is a strong air flow, a significant thermal energy gap is generated. There was nothing I could do to prevent the loss.

Up until now, sufficient attention has often not been paid to perfecting the connecting and pivoting parts of folded sliding doors due to the risk of disaster.

Conventionally, the requirement that the unavoidable gaps in such areas must be so small that, for example, even a child's fingers cannot be caught in them at all locations on the door panel has not often been fully met. I couldn't do it.

According to German Patent No. 1 509 252, the door panels are pivotably interconnected by means of a U-shaped covering strip in cross section, the pivot axis of the door panels being in the plane of a cover rail. Folding and sliding doors having multiple door panels, such as those shown in the above, are known.

The configuration of the longitudinal edges of the folding sliding door and of the cover rail proposed in this document is not suitable for technical reasons in order to eliminate the necessary longitudinal gaps between the pivotable parts.

The present invention is designed to ensure that the longitudinal gaps in each door plate (QM) of a folded sliding door are sufficiently sealed in the closed position of the door, and that these gaps cover all of the door plates. The object of the present invention is to construct an N-sliding door that is folded so as to be small enough to eliminate the risk of an accident in a turning position.

This problem involves a folded sliding door having the type of structure described at the beginning of the text, in which each connecting member has its center of curvature on the pivot axis and is divided into four equal parts extending along the longitudinal direction of the connecting member. two spaced apart outer cylindrical walls having cross-sections of the exemplary shape, and a free end of a girder plate provided along the longitudinal side of each door plate for each of these circumferential cylindrical walls; The solution is to make them face each other.

This outer cylindrical wall having a constant curvature can be combined with the respective girder plates facing it so that the gap between them at the pivot portion can be selected to be almost arbitrarily small;
This is the same size at all pivot positions of the door plate, and as will be described later, by separating the two pivot axes from each other on the inner cylindrical wall, the curved portion of the outer cylindrical wall is separated from each other. However, even when the free ends of the girder plates are folded together, they can be spaced far enough apart to prevent fingers from getting caught between them, even when the sliding door is in the closed position. This has the advantage of eliminating the risk of accidents.

In a preferred embodiment of the invention, each of the connecting members has an inner cylindrical wall section with a cross-section in the form of two further longitudinally extending quadrants, the center of curvature of which also lies within the pivot axis. However, the ends of two separate girder plates face each other.

By this design, the sealing effect is further improved, since two interspaces, which form an air cushion, are arranged one behind the other in all swivel positions of the door. It is the body,
Furthermore, when the folded folding door is opened and closed, the inner cylindrical walls make an acute angle with each other and have protrusions described later, and are independent from each other, so the girder plates facing these inner cylindrical walls come into contact with each other. Since the center of rotation of these girder plates is in a separate pivot axis, there is no risk of pinching fingers, hands, etc. by these girder plates, and, moreover, if appropriate dimensions are selected, It is possible to obtain the ideal appearance of the inside and outside of the folded S-shaped sliding door.

For structural and optical reasons, it is advantageous for the girder plates to adjoin, respectively, the outer and inner wall surfaces of the door plate.

Advantageously, the outer cylindrical wall and the inner cylindrical wall are connected by a cross web.

Insulation may be provided between the outer and inner cylindrical walls.

It is advantageous if a sealing band is provided along the longitudinal direction of the girder plate.

According to another important feature of the invention, in the closed position of the door, the extended end of the cylindrical wall is in contact with a sealing cushion member fixed to the inner or outer wall surface of the door plate.

This sealing cushion element serves as a stop for limiting the pivoting movement of the door plate in the open position of the door, and it provides an additional sealing means in this position, since the above-mentioned front and rear arrangement This is because the air cushion between the two gaps is divided into two parts.

The division of the air cushion in this pivot into three parts and thus an additional improvement of its sealing and heat-insulating action makes it possible to connect the pivot hinge in the following way: A strip with a pin is formed on the connecting member, and the connecting pin is configured to be pivotable in a joint sleeve formed on the inner or outer wall surface of the door plate and having a longitudinal slit. This can be achieved by

The invention will be explained in more detail below with reference to one of the embodiments shown by way of example in the accompanying drawing, in which: FIG.

The three door plates 1, 2゜3 are constructed as double walls,
In this case, the outer wall 10 and the inner wall 11 are made of a slatted board, and a heat insulating material is inserted into the walls.

When the sliding door is closed, the inner wall 11+m is in contact with a support rail 13 fitted into the floor 12 (see Fig. 2), and a corresponding similar support rail (not shown) It is also provided on the lower side of the holding portion 6.

The three door plates 1, 2, 3 are arranged facing each other on the longitudinal side 14 (by means of a connecting member 15 provided with a concavo-convex structure, and are sufficiently connected to each other by respective inner cylindrical wall portions (to be described later) within this connecting member 15. Two separate vertical pivot axes 16 and 170
They are connected to each other so as to be able to rotate around each other.

A corresponding and similar connecting member 18 is provided between the first door plate 1 and the door frame support 5, to which the door plate 1 is pivotably connected.

The connecting element 15 is pivotally connected to the door plate 1.2.3 by three hinges 19 (see FIG. 1) which are arranged at different heights.

When opening the folding/sliding door, these door plates 1.
2.3 are slid in the direction of the arrow 20, and at the same time these door plates 1.2.3 are moved in the direction of each other and away from the door frame 4 (in the position indicated by the dotted line in FIG. 2), corresponding to each arrow 21. f) These door plates are turned toward the front side until they finally come into close contact with each other in parallel and are in contact with the wall 7 of the building perpendicular to the surface of the door frame 4 and stand on their own.

A specific example of the connecting member 15 (see FIG. 3) having a concavo-convex structure according to the present invention is made of an extruded aluminum material.

This connecting member 15&m plane has two well-spaced outer cylindrical walls 22.22' in the shape of a circle divided into four parts, and two further inner cylindrical wall parts 23.23', which also have a cross-section in the form of a quartered circle. have.

All these outer cylindrical walls 22.22', inner cylindrical walls 23.23' extend in the longitudinal direction of the coupling member 15 and are connected in pairs at their respective longitudinal edges.

In the well-spaced outer cylindrical walls 22, 22', this connection takes place through a continuous transition by straight connections 24, while the inner cylindrical walls 23, 23' are formed by narrow projections formed at acute angles to each other. 25.

The outer cylindrical walls 22, 22' both have equal radii of curvature 27 on their outer sides 26 and between which the wheel center 28
are in each pivot shaft 16 and 17 which separate the husband and wife from each other.

The inner cylindrical walls 23 and 23' also have matching radii of curvature 30 on their inner surfaces 29, while the wheel center 31 also lies in the respective pivot axes 16 and 17.

The radius of curvature 27 is larger than the radius of curvature 30.

Each outer cylindrical wall 22.22' and inner cylindrical wall pair 23, 23' has a girder plate 32.32' and 33°3.
The free ends of the girder plates 32 and 32' face each other with a slight distance between them, and the ends of the girder plates 32 and 32' are spaced far apart enough to avoid pinching fingers, and the ends of the girder plates 33 and 33' Since the inner cylindrical wall portions 23, 23' are always connected to each other, there is no risk of fingers or the like being caught.
