Ways to execute the invention

Referring to the 1 and 2 the invention consists essentially of a lock body 10 a number wheel set 20 one lever member 30 , a locking block 40 and a cylinder lock 50 ,

The lock body 10 at least includes
a first housing part 11 , the several openings 111 through which the number wheels 20 from the first housing part 11 stick out and can be turned, and
a second housing part 12 on which the number wheel set 20 is arranged and the first wall 121 and a second wall 122 which has a receiving space 125 form, wherein the second housing part 12 on the top of a hanger 123 forms, its end 124 from the second housing part 12 has a distance.

The number wheel set 20 comprises a spring element 21 ,

The lever element 30 at least includes
a latch 31 at one end of the lever element 30 is provided and at the end 124 of the temple 123 can rest, causing the bracket and the second housing part 12 to form a closed space,
an increase 32 that at the the number wheel set 20 facing side of the lever element 30 is provided and against the spring element 21 can be pressed
an arm 33 who is going to the locking block 40 extends and over the second wall 122 of the second housing part 12 lies,
a hole 34 that goes through the arm 33 extends and through which the lever element 30 with the locking block 40 is connected, and
a printing part 35 which is attached to the locking block 40 opposite side of the lever element 30 is provided and between the bolt 31 and the arm 33 located.

The locking block 40 at least includes
a recess 41 that in the second wall 122 facing side of the locking block 40 is provided and a spring element 411 picks up that between the recess 41 and the second wall 122 is located and a variable distance between the locking block 40 and the second wall 122 holds,
a pin 42 passing through the hole 34 of the lever element 30 to be led,
an opening 43 for the cylinder lock 50 , and
a slot 44 through which the cylinder lock 50 in the opening 43 can protrude.

The cylinder lock 50 is in the recording room 125 taken and includes at least one cylinder core 51 who is a keyhole 511 through which a key 60 in the cylinder core 51 can be plugged to the cylinder lock 50 to open or close. A locker 51 extends from the cylinder core 51 to the slot 44 and connects to a closing element 513 ,

Thereby arises the combination lock according to the invention with a independent Cylinder lock.

How out 3 it can be seen, if the code number is not met, is the lock body 10 locked. Here is the spring element 21 locked and can not by pressure on the pressure part 35 of the lever element 30 from the increase 32 be compressed.

How out 4 it can be seen when the code number is taken, is the lock body 10 unlocked. In this case, the spring element 21 by a pressure on the pressure part 35 of the lever element 30 from the increase 32 be compressed, whereby the lever element 30 around the hole 32 is rotated, so that the bolt 31 the end 124 of the temple 123 leaves.

How out 5 it can be seen if the code number is not taken and the cylinder lock 50 is closed, is the closing element 512 in the opening 43 of the locking block 40 locked, causing the locking block 40 is immovable, so that the lever element 35 not by a pressure on the pressure part 35 can be turned.

How out 6 it is evident when the key 60 in the cylinder core 51 of the cylinder lock 50 is plugged and the cam 512 turns, becomes the closing element 513 entrained and thus through the slot 44 from the opening 43 can escape, so that the locking block 40 is released and can be moved.

In this case, the lever element 30 by a pressure on the pressure part 35 around the increase 32 be rotated, causing the locking block 40 is entrained and the spring element 411 compresses, so that the bolt 31 the end 124 of the temple 123 leaves. Therefore, the lock body 10 open.

• 1. Einfacher Aufbau: Durch ein einziges Hebelelement kann das erfindungsgemäße Zahlenschloß neben der Codezahl auch mit einem Schlüssel geöffnet werden.
• 2. Das Zylinderschloß ist eine Option; Da das Zylinderschloß unabhängig von dem Zahlenschloß ausgebildet ist, kann das Zylinderschloß entfallen, ohne das Zahlenschloß zu beeinflußen.

The advantages of the invention are summarized below:

• 1. Simple structure: By a single lever element, the combination lock according to the invention in addition to the code number can also be opened with a key.
• 2. The cylinder lock is an option; Since the cylinder lock is formed independently of the combination lock, the cylinder lock can be omitted without affecting the combination lock.

The above description only sets is preferred embodiment of the invention and is not intended to serve as a definition of the limits and scope of the invention. All equivalent changes and modifications are within the scope of this invention.
