Description:

Safety door sign

The invention relates to a security door sign with an outer sign and an inner sign that can be screwed to the outer sign.

The object of the invention is to design such a security door sign in such a way that it both meets the requirements of security level 3 according to DIN or RAL and has an attractive appearance.

This object is essentially achieved according to the invention in that the screw connection has M8 screws, the threaded end of which opposite the screw head is screwed into the outer shield from the inside without penetrating it, the screw head of which is accommodated in an opening in the inner shield that is adapted to the shape of the screw head, and in that the screw head of the M8 screw is made completely or partially invisible by means of a cover cap or a cover shield.

By using commercially available and therefore inexpensive M8 screws, security level 3 according to DIN and RAL can be easily achieved. Due to the way the M8 screws are connected to the outer plate and the inner plate and the cover of the screw head, an elegant fitting is created that also meets high demands. 35

Cover caps assigned to the individual screw heads can be securely fixed, for example, by using a fastening section to secure them in a blind hole in the screw head of the M8 screws. This could be a press fit, but preferably the fastening section is a threaded section and the blind hole is a threaded hole, so that the cover cap can also be easily removed again if necessary.

The cover plate provided in an alternative embodiment of the invention can be secured, for example, by means of fastening bolts in blind holes in the screw heads of the M8 screws. This can also be done by means of a press fit, but preferably the fastening bolts are fastening screws and the blind holes of the M8 screws are threaded holes, so that the cover plate can also be easily removed.

Regarding the positioning of the inner plate relative to the outer plate and the appearance of the security door plate, the M8 screws are preferably countersunk screws. The screw heads of the M8 screws can preferably be flush with the door— inside outer surface of the inner plate.

For the same reason, the cover plate can also have openings adapted to the shape of the screw head of the fastening screws, whereby the fastening screws are preferably countersunk screws, in particular raised countersunk screws.

In a further embodiment of the invention, it is provided that the screw heads of the fastening screws are aligned with the outer surface of the cover plate on the inside of the door.

Furthermore, it is advantageous for the appearance of the security door sign if the cover sign is adapted to the shape and size of the inner sign.

A secure connection of the M8 screws to the outer shield, without endangering its external appearance, can be provided by connecting the M8 screws to the outer shield via threaded inserts.

Further aims, features, advantages and possible applications of the invention emerge from the following description of embodiments based on the drawing. All described and/or illustrated features form the subject matter of the invention, either individually or in any combination, regardless of their combination or their relationship.

Show it:

Fig. 1 shows a vertical section through a safety door sign incorporating the invention according to an embodiment of the invention, and

Fig. 2 is a representation corresponding to Fig. 1 for another embodiment of the invention.

The safety door plate according to Fig. 1 and 2 consists of a relatively strong outer plate 1 and an inner plate 2 with a lower material thickness, which can be screwed together with the interposition of the door leaf (not shown) in the space 22. A push button 18 is attached to the outer plate 1, for example, and a guide bush 19 for receiving a latch 23 or the like is provided on the opposite side of the inner plate 2. In opposite openings of the outer plate 1 and

A locking cylinder 20 is arranged between the inner plate 2 and a corresponding opening in the door leaf, which is covered on the outside of the door in a manner known per se (DE 94 06 986 UI) by a spring-loaded cap insert 21. 5

The screw connection consists of several, in the case shown three, M8 screws 3, which are connected with their threaded end 5 to the inside of the outer plate 1 via axially adjustable threaded inserts 17. The threaded inserts 17 are accommodated in threaded blind holes 24 on the inside of the outer plate 1. The M8 screws 3 are designed as countersunk screws; their screw head 4 is accommodated in an opening 6 in the inner plate 2 in such a way that the surface of the screw head 4 on the inside of the door is flush with the outside surface of the inner plate 13 on the inside of the door.

In the embodiment according to Fig. 1, the screw heads 4 of the M8 screws are provided with cover caps 7. The cover caps 7 each have a fastening section 9" designed as a threaded section, which is screwed into a blind hole 10 designed as a threaded bore. In this way, the screw heads 4 are completely covered on the inside of the door. The cover caps 7 can be made of the same material as the inner plate 2, so that a uniform appearance is created.

In the embodiment according to Fig. 2, a cover plate 8 is attached to the inner plate 2 on the inside of the door, which is adapted in shape and size to the inner plate 2. In the area of the M8 screws 3, the cover plate 8 has openings 15, in which fastening bolts 11 designed as screws are countersunk with their screw heads 14. In the case shown, the fastening bolts 11 are raised countersunk screws, the screw head surface of which is essentially flush with the outer surface 18 of the cover plate 8 on the inside of the door.

In this case, the M8 screws 3 are provided with blind holes 12 designed as threaded holes, into which the fastening screws 11 can be screwed.

In both versions, the M8 screws 3, which spoil the aesthetic impression of high-quality door fittings and ensure security level 3 according to DIN and RAL, are invisible. In the first case, they are completely covered by the cover caps 7, in the second case partially by the cover plate 8 and partially by the screwed-in fastening screws 11.
