DE3518563A1 - Closing-sequence control of a two-wing door - Google Patents

Abstract

The invention relates to a closing-sequence control which can be used particularly on two-wing safety doors, in order to ensure that the so-called standing wing, after being opened, is first to assume the closed position again. The closing sequence control takes place via a linkage (51/52) which is arranged behind the frame towards the wall. A closing-sequence mechanism (4) controlled from the standing wing (2) is arranged in the frame (3) and acts on the passage wing (1). The arrangement of the closing-sequence mechanism (4) is provided approximately at mid-height between the two hinges 11/12. A leg spring (42) drives the buffer (41) into the free space (8) when both wings of the door are opened. The buffer (41) stops the independently closing passage wing (1) until the likewise independently closing standing wing (2) actuates the angle lever (7). <IMAGE>

Description

Closing sequence control of a double-leaf door

In the case of double-leaf security doors, such as fire doors, automatic Closing means, such as door closers, are mandatory.

If both door leaves are opened, a closing sequence must be provided otherwise the door leaves cannot be closed properly.

The passive leaf must come into the closed position with priority so that the The active leaf can close. To ensure this closing sequence are various devices have been developed.

The closing sequence regulators on the market are of their own type complex rods, which are mechanically susceptible and not from willful destruction are sufficiently protected. The arrangement of this complex linkage is mostly provided on the head frame or in the free passage under the head frame. All However, arrangements are not architecturally desirable.

The object of the invention is to provide a closing sequence control to develop, which has a simple mechanics and an architecturally inconspicuous place and a not easily destructive access is exposed.

Another object of the invention is to provide a closing sequence control of the type mentioned at the outset to propose which, taking into account all relevant Safety regulations are used regardless of the door leaf width and type of door can be.

The task of the invention is solved by a closing sequence control, wherein the closing sequence mechanism is arranged on the poultry between the two door hinges is. The switch linkage, which starts from the inactive leaf, is between the frame and Wall, with a corner drive the linkage from a horizontal in diverts a vertical position.

The holding force is increased by the arrangement of the closing sequence mechanism Favorably distributed over the door on the door hinges towards the frame.

Due to the rod arrangement behind the frame towards the wall, the Switching movement not influenced.

Part of the implementation of the closing sequence control according to the invention is Resilient buffer that moves into the free space between the active leaves when the door leaves are open and frame pivots, the pivoting movement being slightly behind the horizontal pivot point is stopped by a stop.

When the door leaves are closed, the buffer is vertical in the frame held. If active and inactive leaves are opened, the linkage is above the angle lever of the inactive leaf the pivoting movement of the buffer is free, this being controlled by a torsion spring is driven.

The invention is based on an illustrated embodiment explained in more detail below.

It shows: FIG. 1 a double-leaf door in the closed position 2 shows the double-leaf door in the closed position with the mechanical one drawn in Solution of a closing sequence control Fig. 3 is a section according to Line I - I of FIG. 1, FIG. 4 shows a detail of the extended locking element in FIG the free door gap when the door leaves are open Door leaves In Fig. 1, a two-leaf door is shown with active leaf (1), passive leaf (2) and encompassing frame (3). Between the door hinges (11/12) is approximately in the middle of the height the closing mechanism (4) arranged by the linkage (51/52) and corner drive (6) is connected to the angle lever (7). In Fig. 1, the individual positions for simple explanation shown schematically.

If only the active leaf (1) is opened, the buffer (41) remains in its basic position as with closed door leaves (1/2).

See Figs. 2 and 3.

If both door leaves (1,2) are opened, a leg spring (42) drives the buffer (41) around the pivot point (40) in the free space (8) between the frame (3) and pedestrian wing (1). The angled lever is created by the rods (51/52) and the corner drive (6) (7) moves. The angle lever (7) is on the frame (3) in the door leaf area of the passive leaf (2) arranged.

Are the door leaves (1/2) through the door closer, not shown in detail closed, the active leaf is closed by running against the pivoted buffer (41) at a corresponding angle for as long kept open until the inactive leaf (2) moves against the leg (71) of the angle lever (7).

The linkage (51/52) exerts a compressive force via the corner drive (6) on the buffer arm (411) and brings the buffer out of its above dead center the stop (31) remain in an approximately horizontal position in the vertical position. Through this priority closure of the passive leaf is guaranteed.

For the leg spring (42) there is an abutment (32) in the frame (3) intended.

To avoid the closing pressure impact of the pedestrian leaf (1) through the buffer (41) to dampen accordingly, damping springs (43) are provided on the buffer lever (412).

Should the active leaf (1) be affected by additional external force are primarily brought into the closed position, the damping springs (43) prevent destruction or bending of the closing sequence control.
