Safety door and safety apparatus for installation in a door
| Details |

A safety door has safety bolts provided at two opposite peripheral edges of the door leaf. By a locking mechanism apparatus, the safety bolts can be shifted into assigned guideways in such a manner, that they protrude beyond the corresponding peripheral edge of the door leaf in a locked position and are accommodated in the door leaf in an unlocked position. The locking mechanism apparatus has a slide rod which can be shifted in its longitudinal direction essentially transversely to the guideways and with which the safety bolts are mechanically coupled. Precisely one safety bolt is carried in each guideway. The safety bolts assigned to the one peripheral edge and those assigned to the opposite peripheral edge are disposed offset to one another. |

DETAILED DESCRIPTION It is an object of the present invention to provide a generic safety door or an apparatus for producing a safety door, for which the operating mechanism for the safety bolts is particularly narrow.
It shall also be possible to construct house and residence doors in this way, without having them appear to be unattractive.
Pursuant to the invention, this and other objects are accomplished for a safety door of the generic type owing to the fact that precisely one safety bolt is carried in each guideway and that the safety bolts assigned to the one peripheral edge and the safety bolts assigned to the opposite peripheral edge are disposed offset to one another.
The offset arrangement of the safety bolts with respect to one another enables the means, which engage the safety bolts directly in order to operate them, to be provided in staggered fashion.
Since only one safety bolt need thus be operated on the level of each guideway, which preferably is constructed as a pipe, and, moreover, operated either at the one peripheral edge or at the opposite peripheral edge of the door, the operating mechanism can be constructed so as to be very much narrower than it is in all known safety doors.
In the case of the inventive door, the width of the operating mechanism is thus reduced owing to the fact that this mechanism serves not for operating two, but rather for operating only one safety bolt per pipe level.
In the case of the operating mechanism by means of guide rods, which is known from the German patent 4128213, as well as in the case of the safety door with safety bolts operated by wedge mechanisms and known from U.
S.
Pat.
No.
819,460, the width of the operating mechanism is reduced to about one third by means of the inventive measure.
Due to the correspondingly narrower construction of the operating mechanism, the latter can be covered by means of a considerably narrower covering strip.
In particular, the operating mechanism can be covered with a covering, the width of which is not greater than that of the metal fittings normally provided on the inside of doors
