Description

Description

Door lock system for standard doors with stop.

State of the art

Apartment door locks generally consist of a slot that is inserted into the side of these doors. To open these doors, fittings are attached by turning them, which retract the snap lock.

problem

The invention specified in claim 1 is based on the problem that a door can only be opened by pushing down the handle, which means that the forearm, wrist and hand have to turn.

In any case, this is a movement that places a lot of strain on this joint structure, as when gripping the handle, a right angle is formed between the hand and the forearm.

For older people, this is often a difficult hurdle to overcome; for people whose arms do not have the usual proportions and therefore cannot reach a normal door handle with their arms, this process often becomes an undignified procedure.

Wheelchair users often have to stretch to even reach the handle.

Solution

Door locking system for standard doors with a stop that opens in one direction, so that you either pull or push the door to open it. The solution to the problem is that you no longer push the handle down and either pull or push the door to open it, but only operate the handle in the direction in which the door can swing.

Benefits achieved:

The problem arises as described above. By comparing the most diverse mechanisms, I have determined that, apart from swinging locks, there is almost always a rotary movement that pulls back the bolt in a door. When designing the locking mechanism I invented, I started from a solution that would make it possible to

to open the door in a variety of ways. For me, this meant inventing a new mechanism that was easy to understand and simple to operate.

Further embodiment of the invention:

A further advantage is stated in claim 2.

The versatile usability makes the fitting mentioned in claim 2 a

important component of the door locking system.

On sheet 2 of the drawings, in Figure 4, a door is shown whose fitting is in the rest position. In this position, the snap lock, Sheet 1 Fig. 2 No. 1, swings freely in the lock, so that when the door is closed, the snap lock snaps into the frame by the spring, Sheet 1 Fig. 2 No. 4. Figure 5 shows the fitting in the actuated position. The fitting is mounted at the lower end with the help of a shaft in the rosette Sheet 3 Fig. 6a (shaft guide) so that it swings freely in this direction only. At the upper end, the fitting is guided through the rosette (bore), Sheet 3 Fig. 6, so that the actuating element, Sheet 1 Fig. 3 No. 2, of the snap lock, Sheet 1 Fig. 2 No. 1, pulls the snap lock back through the guide in the released direction and the door can be opened. Forces now occur in the fitting which return the fitting to its original position. These forces are supported by the spring, sheet 1 Fig. 1 No.3.

Claims (2)

Protection claims 1) Door lock system for standard doors with stop. Characterized, that you no longer press the handle down and either pull or push the door to open it, but only operate the handle, drawings sheet 2 Fig. 4-5, in the direction of the door, i.e. in the direction in which the door can swing freely, in the rest position the snap lock sheet 3, Fig. 2, No. 1, swings freely in the lock, so that when the door is closed the snap lock snaps into the frame by the spring (sheet 1, Fig. 2, No. 4). In the actuated position, the latch is supported at the lower end by a shaft in the rosette sheet 3, Fig. 6a, (shaft guide) so that it can swing freely in one direction only. At the upper end, the handle is guided through the rosette (hole), sheet 3, Fig. 6, so that the operating element, sheet 1, Fig. 3 _S No. 2, of the snap lock, sheet 1, Fig. 2, No. 1, retracts the snap lock through the guide in the released direction and the door can thus be opened. The forces occurring in the fitting are supported by a spring, sheet 1, Fig. 1, No. 3, which returns the fitting to its rest position. 2) Door handle (fitting) according to claim 1, characterized in that the latch, as in the drawings Sheet 2 Fig. 4-5, is pulled or pushed in the actuation direction of the door. The latch moves the actuation element (Sheet 1, Element 2) by which the snap lock (Sheet 1, Element 1) is retracted. The latch is held by four rosettes (Sheet 3, Fig.6) which are arranged at the ends of the latch as on Sheets 4 and 5 so that the rosette holds the latch at the lower end with the help of the shaft, at the upper end, through the actuation element, through the door and the rosettes attached at lock height, so that it is returned to its original position by the spring Sheet 1 Element 3 after actuation.
