DE3220409A1 - Fully automatic roller shutter closure - Google Patents

Abstract

The invention relates to a corner-deflecting steel bolt locking system which connects the respective roller armour at its lowest profiled rod rigidly to the guide rail by latching into a corresponding bore. The automatic release of the locking system is brought about when the roller armour bears firmly with its lowest profiled rod on the window sill and approximately three further profiles lie closely on one another. The unlocking is triggered by a pull strap fastened to the top profiled rod accessible from the inside being tightened, for the purpose of unlocking, only when the roller armour is operated properly and at the same time the lowest (three) profiled rods also are pulled to slotted position. The closure is to be mounted in a covered manner on the left and the right and can be applied easily by amateurs with reference to the mounting instructions without previous demounting or other modifications. It is consequently possible for the first time to fix roller armour in its lowest position fully automatically. The economic advantage lies in the a) increase in burglarproofness, b) reduction in mounting outlay, c) avoidance of damage by faulty operation (e.g. electric drives), d) universal applicability on all roller armour types (e.g. wood, plastic, aluminium etc.). <IMAGE>

Description

PATENT DESCRIPTION for the patent application dated May 28, 1982 Title: FULL AUTOMATIC ROLLER SHUTTERS 5 Area of application: The automatic shutter lock is used primarily for subsequent burglary protection of Eolz, plastic and metal roller shutters and roller doors.

Stand d d der T e c h II i k It is known that roller shutter closures, if they have a certain automatic function, this only with a relatively large one Assembly effort can be assembled. This applies in particular to the subsequent Equipment. An at least rudimentary pushing up of the roller shutter from the outside however, they cannot prevent it.

K r i t i k des 5 t a n d e 5 der T e c h n i k None of the currently Roller shutter closures with Automatic on the market can have a similar effect without loosening and opening the most, covered by paintwork and wallpaper Mount the roller shutter box. In most cases, the Rolipanzer is off the shaft solved or completely expanded. For roller shutter closures that require this work make, the assembly costs exceed the material value many times over. Shutter locks Without automatic characters it is easier to assemble, but incorrect operation and consequential damage. (e.g. in the case of an electrically operated roll-up armored car, this Forgot to unlock before pulling up.) Task: The invention is the task based, roller shutters of all profile types against burglary by levering up and pushing up of the roll-up curtain - fully automatic - to be secured.

Furthermore, to be able to use this advantage with -all- types of roll-up armor and reduce assembly costs.

Solution These objects are achieved according to the invention in that in an extremely flat steel lock case a corner-deflecting bolt lock is installed (sketch 1) and this with its bottom bracket, from the outside inaccessible, is screwed to the lowest profile bar.

The steel locking bolt (sketch 1 - part A) is through the 9o offset connecting rod with guide sleeve and delay spring (sketch 1 Part B) with congruent position of the locking bolt (part A) and the, on the inner leg of the U-shaped roller shutter guide profile attached strike plate hole (sketch 1 part C) in the lateral locking position brought.

The delay spring has the task of locking it First take up the thrust and when the locking position is reached, the locking bolt (Part A) into the striking plate hole (Part C).

The automatic unlocking is achieved in that the.

reverse order of the locking process by the one on which the topmost profile bar, which can be reached when the window is open (sketch 1 part D) is triggered via a reversing lever (sketch 1 part E). The tension belt (Part D) is dimensioned in its length in such a way that a tensile effect only begins when when all profile bars except for the three lowest are evenly in the slot position are sucked. This can only be done from the inside using the normal shutter operation by belt, crank or electric motor. The delay spring (part B) now has recorded the opening path in the opposite direction and brings after lifting the lowest profile bar from the window sill the connecting rod back to the starting position. When the shutter is lowered again, the roller shutter is automatically locked again.

Achievable advantages: 1. No lifting or pushing, however slight of the roller shutter like this with all other automatically acting safeguards the case is.

2. Suitable for all types of roller shutter curtains (wood, PVC and metal) independently from the profile construction such as single-walled, double-walled, with or without chamber webs, Foaming etc.

3. Lowest assembly effort, without opening the shutter box, without Loosening or removing the roller shutter. Time-Cost-4. Absolutely free from operating errors. -Savings Blank page
