This invention relates to the castle of the closure of the door tight door. In particular, the invention relates to the lower castle of the closure of the door tight.

Figure 1 shows two well-known way of locking the inactive door door. door consists of a work of a door cloth 1 and nonworking door leaf 2. Working leaf 1 and outside the door cloth is also called a working door and inner door. Working the door is the door to the normal application, which shall, when through the doorway do not need to carry larger loads. If you want to carry a larger things through the doorway, for example, while driving, opening the working of the door leaf does not necessarily create a large enough opening. In this case, open also outside the door leaf. Usually outside the door shut in the design 4 door frame of the doorway and level 3 sex.

Working leaf 1 and outside of the door leaf 2 are mounted with the possibility of rotation to design 4 door frame of the doorway through the hinges. Usually working the door leaf 1 contains castle 5, containing a tab 6. When a door 1 lock, tab 6 is partly inside the chassis 7 lock brakes, thereby shutting working the door at the broken door. Lock case with latch is also called a lock with a latch, and Vice versa, because in practice the body performs the functions of the castle. Because the broken door 2 merges with the design 4 door frame of the doorway and level 3 sex, the broken door, you can neither turned nor a lock in a working door. We can say that in normal use, broken door is part of the design 4 door frame of the doorway. Unlocking the working door 1 is carried out as usual, and the door opens normally.

Building 7 lock with locking merged with terminals 9, 10, established in nonproduction 2 door and locking broken door in the design of the door frame of the doorway and into the floor. Recess 12, 11, which are the ends of fixing rods, when broken, the door is locked situated in the construction of 4 door frame and level 3 sex. In the lock case with latch is located stimulates tool 8 out rods inside wall of the door so that the ends of the rods out of the grooves 11, 12, are in the design of the frame and a floor level. From this action, and taken the name rods. When rods pulled inside wall of doors, broken door can be opened, i.e. turn. Its typical stimulates tool 8 contains manually rotatable lever. In some well-known technical decisions stimulates tool 8 is not locked in connection with the lock body with a dead lock of the door, but instead is made as a separate site and connected with rods. rods you can also return back to the acting position inside wall of the door, using the means of disengaging 8, due to which the broken door again can be locked in the design of the door frame and a floor level.

Another way of locking wall-door - through the use of separate castles on the top edge and/or bottom edge of the closure of the door leaf. Figure 1 illustrates an implementation option in which the top and/or bottom edge of the closure of the door leaf has a locking 13. This castle contains the latch 15, which is located in the projected position when the door is locked. Latch the top of the castle 15 locks broken door frame 4 and latch 15 of the lower castle broken locks the door on the level 3 sex. Locking doors eliminated when starting working the door, so it can extract managing wedge 14 castle 13. Ledge Manager wedge directs the latch 15 inside the castle, whereupon the broken door can be opened. Locking by, when we again turn a working door-to-wall doors, resulting managing wedge is pushed inside the castle and at the same time send latch 15 in the castle.

The problem with such upper and lower castles is that managing a wedge 14 resists the closing and opening of the working doors. Castle 15 has a spring-spring system, wedge from the castle. Then managing wedge pressure on working the door. This reduces the usability of the working door. In addition, if the door is combined with door automatics, the castle of the 13th may also resist the device door opening and closing.

There are also technical solutions, which ends 9, 10 cores are connected with the upper and lower castles wall of the door. Because of this, the reeds of the upper and lower castles, not ends rods, lock broken door in the design of the door frame and a floor level. The work of the upper and lower castles can be controlled by releasing funds 8, acting through rods 9, 10.

The task of the invention consists in the creation of the lock off the door leaf, causing minimal inconvenience when using the working doors. This goal is achieved as described in an independent claim of the invention. In dependent claims describes different ways of carrying out the invention.

Castle 16 of the closure of the door leaf contains housing 23 lock, latch 17 and managing wedge 18. This control wedge is made with the possibility of linear displacement in the position in which he was nominated from the castle, and the position in which he allotted to the inside of the castle. The castle also contains the lever 20, a leading element 21 and spring system 27. His first end of the lever 20 is mounted with the possibility of rotation, which is the position of 25, to a Manager of Klin 18, and the other end is attached with the possibility of rotation, which is marked position 24, the lead item 21. The leading item 21 is also attached with the possibility of rotation, which is marked position 22, to the chassis 23 of the castle, and the leading element contains managing Cam 26, associated with the latch 17. The spring system 27 executed with the possibility of rotation of the leading element to the situation in which the control Cam 26 holds latch 17 inside the castle, and the managing wedge 18 and is in the extended position.

Lever 20 and a host item 21 implemented with the possibility of power transmission spring system 27 the managing wedge 18 so that the power of parallel linear movement of the managing wedge is the greater, when the wedge is in the extended position, and is the smallest in the situation when the Manager of the wedge allotted to the inside of the castle.

Below is a more detailed description of the invention with reference to the accompanying drawings, where:

figure 1 shows examples of known ways of locking wall of doors;

figure 2 shows an example of a castle, corresponding to the invention;

figure 3 shows an example of the castle, the relevant invention, in a locked state;

figure 4 shows an example of a castle, corresponding to the invention state; and

figure 5 shows an example of a castle, corresponding to the invention, on the side.

Figure 2 shows an example of a castle, relevant to the invention. Castle 16, corresponding to the invention, are mainly designed for installation on the bottom edge of the wall 2 door, as shown in figure 2. Lock latch is located on level 3 sex and the control of Klin in the working door 1, when panels door closed. Optionally, in the castle you can provide a connection point through which you can connect with the latch rod 10. The connection point is a hole, equipped with an internal thread, the latch of the lock, which can be screwed rod. End rod often supply external thread. rod provides control locking manually and by using a management tool, such as managing the lever quickly is associated with one end of rod.

Figure 3 shows an example of a 16th, corresponding to the invention, when the lock is in the locked position. The castle contains a body 23 lock, latch 17 and managing wedge 18. Managing wedge is made with the possibility of linear displacement in a position where he is nominated from the castle and in a position where he allotted to the inside of the castle. Managing wedge preferably represents the so-called light latch, as shown in figure 3. Managing wedge also may be a normal splay latch.

Castle additionally includes a lever 20, a leading element 21 and spring system 27. His first end of the lever 20 is mounted with the possibility of rotation, which is the position of 25, to a Manager of Klin 18, and the other end is attached with the possibility of rotation, which is marked position 24, the lead item 21. Bracket with the possibility of rotation can be done, for example, by axial roller. In addition, the lead element can be attached with the possibility of rotation, which is marked position 22, to the chassis 23 of the castle. Leading element also contains managing Cam 26, located in contact with latch 17. The term «loose contact» means that when the latch is withdrawn, managing Cam provides the movement of latch-up, i.e. the connection between the governing Cam and a latch is disposable. The relationship between the latch and managing the Cam is supported mainly in different situations use of the castle. In other words, the physical contact between the latch and managing the Cam is the main point of contact.

The spring system 27 executed with the possibility of rotation of the leading element to the situation in which the control Cam 26 holds latch 17 inside the castle, and the managing wedge 18 and is in the extended position. Figure 4 shows this situation.

Figure 3 managing wedge 18 shows the inside, i.e. force in the direction of movement of the wedge is the lowest. When a door is opened, managing wedge may come out of the lock case, because popped spring system 27. The force of the spring system turns leading element 21, which in turn transmits the force of the spring system on the lever 20. Lever transmit power control wedge. When the control lever moves thus, the mutual position relative to each other host item 21 and lever 20 changes, affects the force is parallel to the movement of managing wedge 18.

Figure 4 managing wedge 18 shows on the outside, i.e. force in the direction of movement of the wedge is the greatest. When the door turns to the wall of the door, the working pushes the door leading wedge into the castle. The force resisting the movement of the working-door, first is greatest, and it decreases when managing wedge mould is pushed into the castle. This also simplifies the closing of the working doors. You may notice that this feature also simplifies the opening of the door.

In the case of a combination of automatic operation with working the door for opening and/or closing of a door lock, corresponding to the invention also simplifies the applicable automatic door devices. Thus, the automatic device is not needed such a large workforce, as in the use of known devices. Automatic device also can be given to the appropriate sizes for low-cost electricity.

3 and 4 shows castle, designed for the lower edge of the wall of the door. As you can see in figure 3, latch 17 castle can move between extended and retracted the provisions of the Manager when the wedge of 18 is in a position where he allotted to the inside of the castle. Thus, latch 17 may move freely from the nominated position where she plays the inside. Gravity tends to hold the latch 17 in its extended position. The advantage of free movement is that the lower latch nonproduction door does not hamper the closing working the doors, if the hole is at floor level for some reason not aligned with the securing tab 17 or if the hole in question, contains garbage, partly to prevent the nomination of a latch.

3 and 4 also shows that the latch 17 contains the control part 17C, primarily associated with managing Cam 26. The control part shown on the drawings is a ledge, but it can also be, for example, hollow, in which establish managing Cam 26. Through implementation options shown on the drawings, you can limit the nomination of this part of the latch 17, propounded of a 16th, i.e. propounded part 17B. Latch 17 in this embodiment, contains ledge 17A, limiting the nomination latch out through a hole in the front placket castle. Latch in accordance with the method of implementation, shown on the drawings, also contains the connection point through which rod 10 can be connected with a latch. Thus, there are a number of different options for implementing the nomination of the latch, the latch shown on the drawings, illustrates a number of indications, integrated by choice.

The spring system 27 in accordance with the method of implementation, shown on the drawings is a system of springs, torsion springs, made with the possibility of connection with point 22 of fastening of the host item 21 to the lock case are such that the first free end of the spring system 27 supported housing 23 of the castle, and the other end of the spring system is supported point 24 of fastening of the host item 21 and lever 20. Figure 5 shows a side view of the spring system. Naturally, you can also embody the spring system other means of rotation of the host item 21.

The drawings you will notice that the front strap 19 castle is L-shaped. The front edge of the front strap contains a hole for managing wedge 18, and the other side contains the hole bolt 17.

If it is desirable to use the lock, corresponding to the invention, on the top edge of the wall of the door so that the latch inside lock case, if the door frame and the door is not aligned or clogged, the castle, corresponding to the invention shall be fitted with a spring or a similar tool to lift the latch.

In light of the above examples it is obvious that an implementation option corresponding to the invention, can be implemented in a number of ways. It is obvious, that the invention is not limited to the examples mentioned here, and can be realised through a number of other implementation options within the scope of the claims to the appended claims.
