Some more skilled people, having in mind this big problem, construct, produce and sell very expensive, various alarm devices, which illusory increase a safety. These devices are very sensible and depend very much on the energy source, without it they can not work. They depend on power source and their power lines have been broken easily. A short circuit may be done easily to them, by water or by other power lines.

Their mounting place is accessible. There are also many other disadvantages decreasing a security, which should be given to people by those devices. d) Presentation of the invention's essence The essence of my invention Universal block system for protection of house's and other's doors is in it, that with its parts, in continuous system making one unit, it is connected with the lock, which have been mounted into doors of various objects all over the world.

It is first of all about the mechanism with combinations, which works and moves various parts, hand activated by lever with handle, mounted from the outside of the block system.

The function of this invention Universal block system is based on it, that through the handle of the transferring lever and other parts, in the pump has been moved the piston, which compresses a very small air quantity and so creates sufficient compression, which through holes on gears and through pipes has been transferred to the air chamber, acting on the small piston and moving it into direction of compression force's action. When this compression force moves the piston into force's direction the piston falls in the hole, an opening which we previously made on the appropriate lock's place or it interposes in front of the strip, keeping the strip from coming back, when we try to act with the key. On this way the blockade of the lock has been making, after prior locking the lock by key.

The unlocking has been making in reverse order, by pooling the piston to the other side than previously. In this case below the piston in pump the vacuum has been created, which through strip's holes and through the pipe has been transferred into the air chamber, pooling the small piston and releases the lock. Now we unlock the lock by the key and go into the house, flat or other room.

Because of these features the invention is practical for the use in all environment and because of it, that no movement of the parts inside the structure can be heard, so it is impossible to discover any secret of the invention, or from outside to detect their movement or relative locations.

On this way it is disabled any try of unauthorized unlocking or releasing of the lock, because it is blocked by this Universal block system. It is provided, that this Universal block system has a wide spectrum of combination changes, and that it is possible, quick and simple, to change the combination for example at this invention where we have mounted four scales, each of 16 numbers and letters which have been used in code combinations so, 10 number 1-0 and 6 letters"a-f". In this case we have got: 16 x 16 x 16 x 16 = 164 = 65. 536 combinations -165 =1. 048.576 combinations It is easy noticeable, that by increasing the number of scales for one or more, the combination figure has been increased towards boundless and that is very important for military objects. Further, it is provided that this invention has been blocked by compression and unlocked by vacuum by which it has been operated and secured the prior by key locked lock in doors of houses and other objects. General characteristics of this invention are mentioned, but the other details, such as for construction, structure and function and advantages as well, which gives my invention, will be better explained in description which is following, which regards to the drawings, belonging to it and which make a part of the patent description. e) Short description of figures and drawings Fig. 1, is outside view of mounted lock"Titan"and of my Universal block system in house's door..

In the same Fig. 1, is presented a disposition of gear 3, with numbers 5, on scales of gear 3. Have been presented the red lamp 53, when the lock is blocked by block system and green 58, when the lock is not blocked by block system.

On the upper part of Fig. 1, on the block system is a cover 28, and below it a micro switch 48, which plugs in battery 46, when the cover is open and by other end and button 64, which switches mechanism for reset in other words for destroying of code at putting the cover 58 down. On the handle 9, is a moving part 10, by which the cover 28 has been locked, in closed position of cover. On the lower part of Fig. 1, in the house's door 1, is mounted American lock TITAN 44, where the opening 59 is, for the key.

On the surface in length between the block system 2 and the lock TITAN 44, is a decorative messing sheet metal 30.

In Fig. 2, is a housing of block system 2, in which four gears 3 (arranged in sandwich) are placed, which the shaft 6 is going through, about which those gears are rotating in both directions. On the gears 3, are the scales 5, with the numbers 1-0 and letters a-f, total 16 marks of each on one scale of one gear 3. On the other side of gear 3 is an outlet with double Archimed curve, which serves, by button reset, which is pressing the pin 64, to put back all numbers to zero after closing the cover 28. In an extension of all four gears 3, are four gears 4, which are rotating around the shaft 7, in both sides. Through the gears 4, are penetrated holes 23 and 24, presented in Fig. 4 and Fig. 5, which should be arranged in an continuous channel 21, when we wish to place our secret code for realization of blockade and unlocking of lock 44, in the door 1, which we prior locked by the key in the opening 59. In Fig. 2 is presented"U" profile 20, in which over the shaft 7, the gears 4 are mounted. On the gears 4 is the opening 22, for taking away the excessive air into the atmosphere when the openings for closing the channel 21, which the air going through, do not coincide. Below the gear structure and gear 4 is an shaft 8, on which is the handle 9 mounted from the front side and the hook 10, with the spring 11, which enables keeping the cover 28 in an closing position.

The cover 28, locks the block system 2, from the front side. The cover 28 is rotating around the shaft 29 and withholds in an open position by the spring 66. On the cover 28 is an extension 57, which disconnects the micro switch 48, when the cover 28 has been closed. When the cover 28 has been opened, the micro switch 48 has been released, the lamp contacts have been linked and the lamps are giving a signal. In this case is turned on a lamp 50, which illuminates the scale 3 and 5 of block system 2 and turns on one red lamp when the lock 44 is blocked or green 58 when the lock 44 is unlocked. This lighting has been provided by two batteries 46 and electrical conductors 54 and 49. From the front side of gears 3 the scales 5 have been illuminated by lamp 50, whose light has been increased by focus-made plastic and spred on above numbers and so it increases the look of numbers and letters. Micro switch 48, lamp 50 and focus-made plastic 52, are fixed for the support 51. From the front side of block system 2 has been placed the pump 15, whose work is presented in Fig. 7, Fig. 8, Fig. 9. In Fig. 7 is presented the position of the piston 16, in lower position, when in pump has been created the vacuum for releasing the lock. This position of the piston 16 is performed so that we turned the handle 9 to one side and by lever 8, the plate 14, to the left and by that we pooled the piston 16 in lower position and so stretched the spring 61, which is connected with plate through the outlet 62, on the plate 14. The piston 15 is by pin 18 linked with the angle lever 17. The angle lever 17 with its leg, going into oval opening 60, is on the plate 14.

The plate 14 is over quadric opening 12 linked with lever 8 and lever 8 with the handle 9. After dropping the handle 9 on the block system 2, the spring will from the position in Fig. 7, the plate 14, with the outlet 62 return into a neutral position Fig. 8, while the piston 16 in pump 15 will remain unmoved. On that way as it is presented in Fig. 8, the spring always returns the plate 14, into the presented neutral middle position with outlet 62 and spring 62 on the way presented in Fig. 8.

Fig. 9, shows an other position of piston 16, when it is moved into upper position of the pump 15 and when it compressed the air and created sufficient compression for blocking the lock 44, by small piston 33, located in air chamber 31 and 32, which does not allow the return of strip 43 in the lock 44 and so keeps the lock to be blocked.

In Fig. 9, as well, has it been seen that the spring 61, is tightened but on the opposite side than the position in Fig. 7. It has been seen also that the elbow of lever 17, in all three figures, Fig. 7, Fig. 8 and Fig. 9 is walking in opening 60 and so enables the piston 16 to remain either in lower or in upper position in the pump 15 and the spring 61 is bringing back the plate 14 unto a neutral position as it is in Fig. 8.

Fig. 6, shows a gearing of parallel gears 3 and 4. The gear 3, can be rotated in both directions around the shaft 6. On the gear 3 are the numbers 5, from 1-0 and letters 5, from"a-f'by which has been performed the secret code on the block system. The gear 4 can be rotated around the shaft 7, in both directions. On the gear 4 is a hole 21, made through the body of gear 4, to the other side. This hole 21, makes a part of channel 21, so that when all four holes have been matched, the continuos channel 21 has been performed as it is in Fig. 4, so it connects to the links 23 and 24, which the air for blockade and unlocking of the lock 44 is going undisturbed through. Like I decried in Fig. 2, it is presented the annulment of numbers 5 and letter as well, in other words mounted is a part of mechanisms which consists of lever 65, linked over shaft 70, with the angle lever 68, which rotates around the lever 69 and with longer end is pressing the formed part of double Archimed curve, so when the cover 28 has been put down, the pin 64 holds back the lever 65 and the lever 65, over shaft 70, holds back the angle lever 68. The angle lever 68 is pressing onto the formed part of Archimed curve and by pressing it skims on the curve, turns over the gear and so brings back all number to zero, in other words it annuls the prior given code.

The annulment of code on the gars 3, block system 2, can be done by hand, so that by fingers we turn the gears 3 to one or an other side.

Moreover, if we forget to do it, it will be done by the cover 28 when we close with it the block system 2.

The spring 71, keeps the angle lever 68, always away from outlet with Archimed curve. The spring 67, enables the holding back the gear 3 in any position when the gear 3 we move for one tooth. The gear 66 on the cover 28 longs to hold the cover 28 in an open position. The spring 11 but longs to hold the cover 28 in an closed position.

However, in order to be understand well, the short description of work of Universal block system with the mounted lock in house's door, consists of it, that when we are leaving home we close the lock 44 first by key, than we find the code of four ciphers 5 and set it on the block system 2. After setting the code we turn the handle 9, and with it also the shaft 8 by which we turned the plate 14 and over angle lever 17, we moved the piston 16 upwards (as it is in Fig. 9) and created necessary air compression below the piston 16. This air compression has been transmitted through the pipe 24 on the gum membrane 34, which is pushing the piston 33 in the air chamber 31 and 32. The piston 33 takes the position as it is in Fig. 2 and prevents the strip 43, to be brought back, as the lock would be unlocked by the key. By that way the lock is blocked by block system. When we close the lock by the key and block by the block system, we can peaceful leave the house.

When we are back, we set the code on the block system 2, turn the handle 9 into opposite direction than previous. All movements will be contrary, so we will, below the piston 16 in pump 15, create the vacuum and unlock the lock, then unlock it by the key and then open the door and go in the house.

When we wish to block our door and from inside we make it only mechanically, without using the code, so that in Fig 10, the handle 40 we move downwards, in that case the lever 39 is pushing the cam 38 down, the cam tooth 38 is pushing the upper leg of the spring 37, and the spring 37, pushing the top of the piston 33, above the outlet 35 and so the piston 33 together with the gum membrane 34 has been moved and performs a blocking the lock.

Unlocking the lock 44 has been performed by contrary way, so that the lever 40 we pool up, then over the lever 39 we pool the cams 38 up and the other end of cam 38 is catching to the transversal shaft 35 and is raising it up and by that pooling the piston 33 as well, so that the unlocking the lock 44 has been performed. After unlocking the lock 44, by key we unlock the lock 44 in the door 1 and free leave the house.

The blocking the lock by Universal block system 2 from outside the door 1 is presented in Fig. 12 and the unlocking in the Fig. 11.

The change of an code on the block system 2 has been performed so that we first open the cover 26 and the bearer 27, with the pump 15. After that we pool"U"profile 20 toward us and release the gears 4 from the gears 3 and then on the gears 3 we are setting new number and letter of new code, rotating the gears 3 to one or to other side.

After setting a new code we push back"U"profile 20 and the gears 3 and 4. The gears 4 have been again matched with the gears 3. At the end we put back the removed parts to their places so that the block system is again ready for blocking and unlocking the lock 44.

Everything described in the detail description is possible to be seen at the demonstration of two samples of prototypes where the locks have been mounted and the block systems produced.

Also all mentioned can be seen on cassettes I have got where are taken the application, operation and function of block system at the blockade and unlocking of the lock in house's-and others door.
