Security doors are needed and usually used as exterior doors to prevent and slow down the entry of unauthorized entrants from the door, but security doors can also be used as intermediate doors. Various security doors are used, for example, in large cities, troubled areas and also in other areas to secure and protect the entrance. Security doors are better equipped than standard exterior doors and have special locks and other security-enhancing equipment. The lock is generally one or more locks that may be located within the body of the door 20. There are also movable locking bars located outside or inside the doors, which are used to secure the doors. These locking mechanisms are often unreliable or complicated or expensive.

: 25. ··. The object of the invention is to provide a security door which • · provides an improvement on existing security doors. In particular, it is an object of the invention to provide a security door in which a security lock is reliable, reliable, simple in construction and inexpensive to manufacture.

The object of the invention is achieved by a security door which is characterized by what is stated in the claims.

• ·. In the security door according to the invention, the locking pins are movably attached to the oblique grooves formed in the shoulders fixed to the rod and arranged to move with respect to the door frame under the guidance of the grooves 2 101242. When the lock body is moved, the lock lever or lock levers move to another position and at the same time move the rod relative to the door. The rod further moves the locking pins which protrude from inside the door frame, 5 go into the counter-holes in the door frame and lock the door frame reliably and securely. In the structure according to the invention, the locking levers can easily turn and move when the lock body is moved. The structure is simple and inexpensive.

The invention will now be explained in more detail with reference to the accompanying drawings, in which Figure 1 shows an embodiment of a security door according to the invention with the frame diagonally side open, Figure 2 shows the security door of Figure 1 seen from the side and partly in cross-section, and Figure 3 shows a partial enlargement of Figure 2.

In the application according to the figures, the security door comprises a door frame 1, a security lock attached to it and an ordinary, so-called day lock 11. The door frame 1 is fixed from the pivoting door frame 4. The safety lock is placed inside the door and includes::: a lock frame 2, two locking levers 5, attached to them: 25 rods 6 and locking pins 3 acting as locking members attached to the rods.

· »» • · · ♦ «♦. ···. The locking levers 5 are attached to opposite sides of the locking body • · · by articulated pins. The other ends of the rods 6 .. 30 are attached by means of pins articulated to the other ends of the lock levers # · *. In this application, the second lock lever and the rod are • · · V * above the lock body and the second lock lever and the rod: * ·. · Are below it. The rods 6 are further attached to supports 7 formed in the door frame and are movable in the vertical direction of the door. Shoulders 8 are spaced * · * * apart on the rods. The locking pins 3 are attached • ♦ *: to the vertically inclined grooves 9 3 101242 in the shoulders 8 movably therein. In addition, the locking pins 3 are supported in a horizontally movable manner on supports 10 fixed to the door frame.

5 The figures show in solid lines the positions of the safety lock parts when the lock is in the closed position and the dashed lines show the positions of the safety lock parts when the lock is in the open position. When the safety lock is in the closed position, the locking pins 3 are protruding and lock the door to the frame. When the lock body 10 2 is turned to unlock the door, the locking levers 5, through them the rods 6 and through them the locking pins 3 move, which press into the door and the door is released from the safety lock. The bar above the lock body and the shoulders attached to it move downwards when opened and the bar and shoulders below it move upwards. The oblique grooves in the shoulders are bevelled so that the locking levers are pulled into the door when the bars are moved as mentioned above. When the safety lock is opened, the opposite action takes place. When the security lock is opened, a standard lock 11 can be used to lock the door.

The invention is not limited to the preferred embodiment shown, but may vary within the scope of the inventive idea formed by the claims.
