The lock is fixed in or on the door.

Action principle of the lock of Fig. 1 is as follows. The key is inserted in the keyhole (see

Fig. 4). When the key bar 36 and the elements 37 having the form of rotating bodies pass the upper arm 23, transfer in the vertical position and move downwards. As they pass the upper plate 4, the elastic nonstretchable body 38 of the key enters the through grooves 27, 9 and 17 of the

arm 23, upper and support plates 4 and 18, and the key bar 36 through the necks 13 of the plates 5 enters the holes 11 and 16. The elements 37 having the form of rotating body pass the holes 16 of the respective support plates 18 and the through groove 17 and lift the plates 4 and 5 up to touching the stay nuts 19. Accordingly, the rods 22 rise, ends of said rods release the bar 6, which by means of a spring moves to the left, the vertical bar 33 moves downwards and the lock is opened. By releasing the plates from the load of key elements, the rods 22 by action of the spring 3 go down on the bar 6 surface. With the purpose of locking the lock, the finger 29 is lifted up from the bar 6 for contacting the synchronously moving handles 7. By turning the synchronously moving handles in the anticlockwise direction, the bars 6 and 33 transfer to the locked position. The plates 4 and 5 under the influence of springs 3 move downwards, thrust the support plates 18 and move down the rods 22, which fix the bars. By turning of the synchronously moving handles 7 in the clockwise direction, the finger 29 moves away from them and under its weight or by action of other force enters the bar 6. In this position the synchronously moving handles 7 are not capable of acting on the finger. The principle of action of the lock presented in Fig. 2 is similar to the action of the lock given in Fig. 1.

The principle of action of the lock presented in Fig. 3 is the following: the key is inserted in the keyhole (see Fig. 4), which turns its guide 35 on the hinge 35' and makes it to take the horizontal position. After disposing the key bar 36 and elements 37 having the form of a rotating body 37, in the guide, the guide 35 under the effect of own and key weight turns on the hinge 35' and occupies the vertical position. The key moves downwards, its elastic nonstretchable body 38, passing the through groove 34 goes out from the guide 35 and through the dovetail cuts 26 and 8 (see Fig. 1), its rod and the elements having the form of rotating body pass the upper plate 4, its elastic nonstretchable body 38 enters the trough grooves 27, 9 and 17 of the upper arm 23 and the upper plate 4, and the key bar 36 through the necks 13 of the plates 5 in the holes 11 and 16, and the elements 37 having the form of rotating body are arranged under the upper plate 4 and plates 5. By pulling the key ring 39, its elements 37 having the form of a rotating body pass through the holes 16 of the respective support plates 18 and the through groove 17 and raise the plates 4 and 5 up to touching the back nuts 19. Accordingly, the rods 22 rise, ends of said rods release the bar 6, which by means of a spring moves to the left, the vertical bar 33 downwards and the lock is opened. By releasing the plates from the load of key elements, the rods 22 by action of the spring 3 go down on the bar 6 surface. With the purpose of locking the lock, the finger 29 is lifted up from the bar 6 for contacting the synchronously moving handles 7. By turning the synchronously moving handles in the anticlockwise direction, the bars 6 and 33 transfer to the locked position. The plates 4 and 5 under the influence of springs 3 move

downwards, thrust the support plates 18 and move down the rods 22, which fix the bars. By turning of the synchronously moving handles 7 in the clockwise direction, the finger 29 moves away from them and under its weight or by action of other force enters the bar 6. In this position the synchronously moving handles 7 are not capable of acting on the finger. Selection of secret code for the lock presented in Fig. 4 is performed by moving the elements 37, having the form of a rotating body and equal or different diameters, on its hinge 36 and by fixing according to the space between the lock plates.

The principle of action of the lock presented in Fig. 5 is as follows: the key is inserted in the keyhole 73 (see Fig. 6), which turns its guide 66 on the hinge 65' and makes it to take the horizontal position. After placing the key bar 69, elements 70 having the form of rotating bodies and the orienting part 71 in the guide, the guide 66 under the influence of own and key weight turns on the hinge 65' and occupies the vertical position, the elastic nonstretchable body 68 of the key, passing the trough groove 67 comes out of the guide 66. By pulling the key ring 72, the key bar 69, elements 70 having the form of rotating body and the orienting part 71 move vertically up in the guide and then in the holes of the lower arm 52, support plates 56 and plates 43 up to touching the back nuts 57 of the respective plate 43 with each element. Accordingly, the rods 59 rise, ends of said rods release the bar 44, which by means of a spring moves to the left and the lock is opened. By releasing the plates from the load of key elements, the rods 59 by action of the springs 42 go down on the bar 44 surface. With the purpose of locking the lock, the finger 64 is lifted up from the bar 44 for contacting the synchronously moving handles 62. By turning the synchronously moving handles in the anticlockwise direction, the bar 44 transfers to the locked position. The plates 43 under the influence of springs 42 move downwards, thrust the support plates 156 and move down the rods 59, which fix the bars. By turning of the synchronously moving handles 62 in the clockwise direction, the finger 64 moves away from them and under its weight or by action of other force enters the bar 44. In this position the synchronously moving handles 62 are not capable of acting on the finger.

Selection of secret code for the lock presented in Fig. 6 is performed by moving the elements 70, having the form of rotating body, on its hinge 69 and by fixing according to the space between the lock plates. The principle of action of the lock presented in Fig. 7 is as follows: the key is inserted in the keyhole (see Fig. 6), which turns its guide 94 on the hinge 93' and makes it to take the horizontal position. The elastic nonstretchable body 68 of the key passing the trough groove 95 goes out of the guide 94. After placing the key bar 69, elements 70, having the form of rotating body, and the orienting part 71 in the guide, the guide 94 under the influence of own and key weight turns on the hinge 93' and occupies the vertical position, the elastic nonstretchable body

68 of the key, passing the trough groove 95 comes out of the guide 94. By pulling the key ring 72, the key bar 69, elements 70 having the form of a rotating body and the orienting part 71 move vertically up in the guide 94 and then in the holes 88 and 79 of the lower arm 81 and plates 77 up to touching with each element 70 the back nuts 85 of the respective plate 77. Accordingly, the rods 87 rise, ends of said rods release the bar 78, which by means of a spring moves to the left and the lock is opened. By releasing the plates from the load of key elements, the rods 87 by action of the springs 76 go down on the bar 78 surface. With the purpose of locking the lock, the finger 92 is lifted up from the bar 78 for contacting the synchronously moving handles 90. By turning the synchronously moving handles in the anticlockwise direction, the bar 78 transfers to the locked position. The plates 77 under the influence of springs 76 move downwards, thrust stay nuts 84 and move down the rods 87, which fix the bar 78. By turning of the synchronously moving handles 90 in the clockwise direction, the finger 92 moves away from them and under its weight or by action of other force enters the bar 78. In this position the synchronously moving handles 90 are not capable of acting on the finger. The principle of action of the lock presented in Fig. 8 is as follows: the key is inserted in the keyhole (see Fig. 6), which turns its guide 96 on the hinge 96' and makes it to take the horizontal position. After placing the key bar 69, elements 70 having the form of rotating body and the orienting part 71 in the guide, the guide 96 under the influence of own and key weight turns on the hinge 96' and occupies the vertical position. By means of the synchronously moving handles the capture 101 is turned in the clockwise direction for inserting the key in the lock. The key bar 69, elements 70, having the form of rotating body, and the orienting part 71 under their weight move downwards and enter the holes of the upper arm 107, support plates 98 and plates 97, up to touching with one of the elements 70 the respective plate. The elastic nonstretchable body 68 of the key passing the trough groove 123, comes out of the guide 96. By means of the synchronously moving handles the capture 101 is turned in the anticlockwise direction, thrusting the orienting part 71 of the key and moving down the elements 70 and their respective plates 97 up to thrusting the back nuts 112. Accordingly, the rods 114 move down, ends of said rods release the bar 105, which by means of a spring moves to the left and the lock is opened. By releasing the plates from the load of key elements, the rods 114 by action of the springs 104 thrust the bar 105. With the purpose of locking the lock, the finger 121 is lifted up from the bar 105 for contacting with the anvil 119 of the capture 101 fixed on hinge 100 of the synchronously moving handles. By turning the anvil 119 in the anticlockwise direction, the bar 105 transfers to the locked position. The plates 97 under the influence of springs 104 move upwards, thrust the support plates 98 and raise the rods 114, which fix the bar 105. By turning of the capture 101 in the clockwise direction, the anvil 119 moves away from the finger 121. The finger under its

weight or by action of other force enters the bar 105. In this position the anvil 119 of the catcher is not capable of acting on the finger.

The principle of action of the lock presented in Fig. 9 is similar to the action of the lock given in Fig. 8. Selection of secret code for the lock presented in Fig. 10 is performed by moving the elements 128, having the form of rotating body, on its hinge 127 and by fixing according to the space between the lock plates.

The principle of action of the lock presented in Fig. 11 is as follows: the key is inserted in the keyhole 136 (see Fig. 10), which turns its guide 133 on the hinge 133' and makes it to take the horizontal position. Its elastic nonstretchable body 131 passing the trough groove 162 goes out of the guide 133. After placing the key bar 127, elements 128 having the form of rotating bodies and the narrowed end of the rod 129 and fixed thereon the elements 130 having the form of rotating body in the guide, the capture 138 by means of the synchronously moving handles is turned in the clockwise direction. The key bar 127, elements 128 having the form of rotating bodies, the narrowed end 129 of the rod and the element 130 having the form of rotating body under the influence of own weight move vertically downwards, its elastic nonstretchable body 131, passing the trough groove 162 comes out of the guide 133. When the element 130 passes the upper arm 146, the narrowed end 129 of the rod enters the through groove 155 of the upper arm, and the rod 127 - the through grooves 144 of the plates 134. The elements 128 are disposed above the respective plate 134. The key rod 127, its narrowed end 129 and elements 128 and 130 move vertically down, up to thrusting the respective plate 134 passing the trough groove 150 of the support plate 135 of one of the element 128. By means of the synchronously moving handles the capture 138 is turned in the anticlockwise direction, thrusting the element 130 and moving down the elements 128 and their respective plates 137 up to thrusting the back nuts 151. Accordingly, the rods 153 move down, ends of said rods release the bar 143, which by means of a spring moves and the lock is opened. By releasing the plates from the load of key elements, the rods 153 by action of the springs 142 thrust the bar 105. With the purpose of locking the lock, the finger 121 is lifted up from the surface of the bar 143. For locking of the lock, the finger 160 is raised from the bar 143 for contacting with the anvil 139 of the capture 138 fixed on hinge 137 of the synchronously moving handles. By turning the anvil 139 in the anticlockwise direction, the bar 143 transfers to the locked position. The plates 134 under the influence of springs 142 move upwards, thrust the support plates 135 and raise the rods 153, which fix the bar 143. By turning of the capture 138 in the clockwise direction, the anvil 139 moves away from the finger 160. The finger under its weight or by action of other force enters the bar 143. In this position the anvil 139 of the capture is not capable of acting on the finger.

The principle of action of the lock presented in Fig. 12 is similar to the action of the lock given in Fig. 11.

The principle of action of the bar system connected by the retainer with one of the rods 168 of the locks presented by Fig. 13 (given in Fig. 1; 2; 3; 5 and 7) is as follows. By lifting of the lock plates 167 and accordingly of the rods 168 with a key (see Fig. 4, 6 or 17), the ridge 173 of the retainer is released and the lever 172 under the weight of the vertical bar 177 turns on the rod 171 in the clockwise direction and the spring-loaded finger 174 releases the ridge 183, consequently the vertical bars 177 and 174 move out of the plates 187, and the bar 181 by moving the finger 179 in the trough groove 182 turns on the rod 180 in the anticlockwise direction, moves out of the plate 187 and the lock is opened, and the retainer lever 172 by thrusting the capture 170 occupies the initial position. For locking of the lock, the spring-loaded finger 184 is drawn out of the vertical bar and by turning of the synchronously moving handles 185 in the clockwise direction, said finger and the bar 177 will be lifted by carrying it over and thrusting the spring-loaded finger 174. The bars 177 and 178 enter the plates 187. At the same time, the bar 181, turned in the clockwise direction on the rod 180 by moving the finger 179 on the through groove 182, enters the plate 187. The lock is locked. By turning the synchronously moving handles 185 in the anticlockwise direction, the spring-loaded finger 184 moves away from them and under the action of the spring or other force, enters the bar 177. In this position the synchronously moving handles 185 are not capable of acting on the finger. The principle of action of the locking device-latch connected with the rods 189 of one of the lock of Fig. 14, presented as well by Fig. 1; 2; 3; 5 and 7, is as follows. By lifting with the key (see Fig. 4 or 6) of the lock plates 188 and the respectively the rods 189, ridge 193 of the locking device-latch is released and the lever 192 is turned on the hinge 191 in the clockwise direction, the lever 192 moves out of the plate 196 and the lock is opened. For locking of the lock, the lever 192 turns in the anticlockwise direction up to thrusting the ridge 196'. At this time the locking device-latch, is included in the door contour. By turning of the synchronously moving handles 194 in the clockwise direction and by thrusting the locking device-latch, the locking device-latch is fixed. After closing the door the handles 194 are turned in the anticlockwise direction and released locking device-latch lever 192 as a result of turning under own weight, enters the plate 196, and the ridge 193 of the locking device-latch thrusts the rods ^' 189, fixes and the lock is closed. In this position the synchronously moving handles 194 are not capable to act on the locking device-latch.

The principle of action of the bar connected with the plates 197 of one of the locks given in Fig. 15 (presented as well by Fig. 1; 2; 3; 5; 7; 8; 9; 11 and 12) is as follows. By moving of the plates with the key up or down vertically, they are released from contact with the ridges 199. The

bar 202 under the action of the spring 201 moves in the guide 200 on the left and the lock is opened. For locking of the door, the spring-loaded finger 203 is moved out of the bar 202 and is thrust to the synchronously moving handles 203'. By moving of said handles in the clockwise direction, the bar 202 moves in the guides 200 on the right, the spring-loaded plates 197 move to the initial position up or down. By turning the handles 203' in the anticlockwise direction, the ridges 199 are in contact with the plates 197 and fix the lock in the locked position. The spring- loaded finger 203 moves into the bar 202, returns in the initial position and the synchronously moving handles 203' are not capable to act on it.

The principle of action of the bars 208 connected with the plates 205 of one of the locks given in Fig. 16 (see also Fig. 1; 2; 3; 5 and 7) is as follows. The spring-loaded plates 205 are lifted vertically with the key (see Fig. 4, 6 or 17), and the elastic nonstretchable bodies 212 in the guides 206 move the spring-loaded with springs 207 bars 208 on the left and the lock is opened. By removing the load of the key elements from the plate 205, the spring-loaded plates 205 move down in the initial position, and the bars 208 under the influence of the springs 207 move to the right in the guides 206. For locking of the door, the spring-loaded fingers 209 are moved out of the bar 208 and are thrust to the synchronously moving handles 210. By moving of said handles in the clockwise direction, the bar 208 moves until it occurs in the door contour. After closing of the door, the handles 210 are turned in the clockwise direction and under the influence of the springs 207, the bars 208 move in the guides on the right, enter in the plates 206' fixed on the door frame and the lock is locked. At the same time, the spring-loaded fingers 209 enter the bars 208, return to the initial position and the synchronously moving handles 210 are not capable to act on it.

The secret code of the lock key in Fig. 17 depends on the diameter and length of the cylinder form elements 213. Action principle of the switchers putting in action of the plates 217 and locking element or alarm means of one of the locks in Fig. 18, (see also Fig. 1; 2; 3; 5; 7; 8; 9; 11 and 12), is as follows. The plates 217 are moved up or down vertically with the key (see Fig. 4, 6, 10 or 17) on the predetermined value, said plates, as soon as they touch the switchers 218 of the means putting to action the locking element or alarm, set in action the drive of the locking element, for example, electric, electromagnetic, pneumatic or hydraulic drive and the lock will open, and during contact of the plates 217 with the switchers 218 of the means setting to action the alarm means, the alarm will be switched on. For locking of the lock, the locking element of the synchronously moving handles will be transferred in the locked position. Positive aspects of the lock: Increase of the lock reliability, that is conditioned by:

1. Assembling of the lock and key by the manufacturer and the consumer with the purpose of selecting or changing of the code;

2. Increase of the secret code quantity in comparison with the other locks, as well as, fitting the other opening means; 3. Placing of the keyhole above or below the lock vertically or shifted upwards;

4. Capability of increasing the space between the lock and the keyhole;

5. Simplicity and compactness of the lock manufacturing;

6. Selection by the owner similar secret codes for using one key for several locks;

7. For opening of the lock, the key inserted in it may be moved in the direction of its inserting or in the opposite direction;

8. Quantity of variable distances between the plates conditions the multitude of the lock secret codes. For example, in the case of five plates and support plates, quantity of the secret codes is more than milliard.
