Abstract
Using such a drive device, the door wing (1 or 2), with the aid of a rotating pillar (5 or 6), is brought out of the door opening. The drive (7) generating the torque for the rotating pillar (5, 6) is arranged on a plate (12) which is supported such that it can torsionally vibrate about at least one axis which is perpendicular with respect to the plate (12), there being arranged in the torsion region of the plate (12) a switching element for interrupting the closing process and reversing the door-wing movement. The means for reversing the door-wing movement is simplified thereby and combined in one structure with the drive thereof. <IMAGE>
Description
(54) A DRIVE ASSEMBLY FOR A ROTARY COLUMN
OF A DOOR WING OF A SWIVEL DOOR
(71) I, DR. ENGELHARD BODE of
Wigandstrasse 7b, 3500 Kassel, Federal
Republic of Germany, a citizen of the Federal Republic of Germany do hereby declare the invention, for which I pray that a patent may be granted to me, and the method by which it is to be performed, to be particularly described in and by the following statement:
The present invention relates to a drive assembly for a rotary column of a door wing of a swivel door. Such a swivel door finds use as a vehicle door.
As is known, in the case of swivel doors for vehicles, the door wings are articulated with the aid of a pivot arm to the rotary column. When the rotary column is turned, then an opening or a closing of the door wing takes place.
The drive of such a rotary column can take place with the aid of a pneumatic piston-cylinder drive or with the aid of another drive resulting in a turning moment.
To avoid accidents, devices must be provided at the long sides of the door wings to prevent a person possibly disposed between the door wings from being wedged in. For this, control means are provided in the long sides of the door wing and effect a switching-over of the compressed air when pressure is exerted on these control means by an obstacle. The effort for this is however relatively great.
According to the present invention there is provided a drive assembly for a rotary column of a door wing of a swivel door, the assembly comprising drive generating means to provide a turning moment to be applied to the rotary column, the drive means being mounted on a plate arranged to be pivotable about an axis substantially perpendicular to the plate, and switch means engageable by the plate in the range of its pivotation.
Advantageously, means for changing over of the door wing motion may become simpler and may be constructionally united with a drive assembly embodying the invention.
An embodiment of the present invention will now be more particularly described, by way of example, with reference to the accompanying drawings in which:
Fig. 1 shows a door with a drive assembly embodying the invention;
Fig. 2 shows the drive assembly of Fig. 1 from the front;
Fig. 3 shows the drive assembly of Fig. 1 from the side; and
Fig. 4 shows a plan view of the drive assembly of Fig. 2,
Referring now to the drawings, the vehicle door shown in Fig. 1 comprises the pivot wings 1 and 2, which are pivoted with the aid of the arms 3 and 4, respectively. The pivot arms 3 and 4 are mounted on a rotary column 6 and 5, respectively.
The pivotation of the rotary column takes place with the aid of drive generating means 7, which provides the turning moment and which according to the exemplary embodiment is arranged at the upper end of the rotary columns 5 and 6.
As Fig. 2 shows, the drive generating means comprises a pneumatic pistoncylinder arrangement comprising a piston 8, the piston rod 9 of which is constructed as toothed rack 9a, which acts on a toothed pinion 10, which is arranged on a shaft 11.
The entire drive generating means providing the turning moment is fastened on a plate 12, which is mounted to be torsionally oscillatable about an axis standing perpendicularly to the plate.
The construction is so designed that three rubber blocklets 13 are, for example, provided under the plate 12 and provided at the end side with metallic fastening pieces 14 and 15, wherein these metallic fastening pieces are fastened on the one hand to the plate 12 and on the other hand to a stationary support plate 16.
The rotary column 5 extends through an opening of the support plate 16 and is connected with the shaft 11, which is journalled in a housing of the piston-cylinder arrangement. Since the plate 12 is mounted to be torsionally oscillatable with respect to the plate 16 and can thus be displaced in a certain manner relative to the support plate 16, possible inaccuracies especially in respect of the axes of the shaft 11 and the rotary column 5 can be compensated. These inaccuracies may, for example, arise as a result of the support plate 16 not standing exactly horizontally.
Arranged in the range of torsional oscillation of the plate 12 is a switch element 17, which provides control pulses when the plate 12 and the driving mechanism disposed thereon move.
If an obstacle is situated between the door wings when the closing movement is proceeding, then the drive generating means, especially the piston 8, has the tendency further to turn the shaft 11 and thereby the rotary column. Since the obstacle prevents this, the plate 12 makes a corresponding reaction motion. Through this reaction motion, the switch element 17 is actuated, whereby the closing process is interrupted.
A switching-over into the door-opening movement then takes place.
According to the exemplary embodiment, the feeler 17a of the switch element 17 bears on the housing 18, which is arranged on the plate and covers over the entire drive generating means.
In normal operation of the driving device, a usual turning of the rotary column and thereby an opening and closing of the door wing takes place. When however an obstacle occurs in the pivotal range of the door wing, then a pressure is exerted on the door wing and also acts back on the drive generating means. Since the drive generating means has the endeavour to turn the rotary column which is however not possible in consequence of the obstacle - the torsionally oscillatably mounted plate, on which the drive generating means is arranged, makes a corresponding reaction motion and triggers switch-over pulses through the switch element lying in the pivotal range of the plate so that the door wing is again opened.
Provided as drive for the rotary column, which is arranged on this plate, can be a toothed rack assembly which in a preferred embodiment comprises a pneumatically actuated piston, the piston rod of which is constructed as toothed rack, which acts on a pinion, the shaft of which lies coaxially in the rotary column.
Of course, any other drive, which results in a turning moment for the rotary column, may be provided on this plate, for example a conventional pneumatic piston-cylinder drive or a V-belt drive or the like.
The torsionally oscillatable support of the plate may comprise one or more rubberelastic blocks which at the end side carry preferably metallic fastening pieces, which are connected on the one hand with the plate which carries the drive generating means and on the other hand with a support plate.

1. A drive assembly for a rotary column of a door wing of a swivel door, the assembly comprising drive generating means to provide a turning moment to be applied to the rotary column, the drive generating means being mounted on a plate arranged to be pivotable about an axis substantially perpendicular to the plate, and switch means engageable by the plate in the range of its pivotation.
