  • the cam member 40 is configured so that the restoration actuating body 13 is actuated in response to the release unlock operation of the button 5 outside side at home when only the unlocking rockers 12a are maintained in the push position when an unlock code correct was introduced after which the button 5 side outside at home can be brought back to its position original and the unlocking rockers 12a are automatically recalled to the no-thrust position to produce the locked state of the device pushbutton lock 1.
  • the part lower end of the slider 17 extends to near the rotation shaft of the sun wheel 31.
  • the travel range of the slider can be brought closer to the solar wheel (drive gear) 31 and that the dimensions outer casing 2 can be reduced. Because of of this, the external dimensions of the device of pushbutton lock 1 can then be reduced and it is possible to easily obtain a reducing the size of the pushbutton device 1.
  • the locking device to pushbuttons 1 of this embodiment can be used, for example, as a locking device for small doors, for which the use of products of the prior art was difficult and, because of the compact configuration of the device push button lock 1 makes it easy to achieve a general cost reduction.
  • the external dimensions of the product of this embodiment could be shortened by more than 20 mm.
  • the slider in achievements in which the slider is moved linearly following the abutment of a release rod, the slider is also considered as being able to be moved linearly by the rod of unlocking the fact that it was planned on the one hand planetary gears that can rotate in one position fixed, on the other hand the layout of a gear circumferential rotatable and to which is attached the release rod, and finally the rotation of the wheel solar, planetary gear and gear outer circumferential sequence.
  • the cam member 40 can be applied to locking devices at pushbuttons of two types for which the operation of rotation of the 5 button outside side at home is either to the left or to the right. Consequently, it is possible to share parts between different pushbutton devices and to obtain a general reduction of costs.
  • this device push button lock can be used in as locking device for locking of doors provided, for example, on the inside.
  • the number pushbuttons to predict and how to dispose, and the device is likely to have applications in which, for example, various push buttons are arranged in one row.
  • the locking device can be a locking device in which a gear drive is connected to a door bolt provided for retractable way through the end surface of side of the door and where the bolt of the door is driven in response to the rotation operation of the element of operation.
  • the description given above belongs to an element of operation with finger parts
  • the constitution and form of the operating element are in no way limited to this and, as an example, it is possible to use an operating element comprising a lever that can be turned by hand and an element of operation comprising a keyhole in which can insert a key to turn the sun wheel.
