Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a lock of a type in which a deadbolt is retracted.

[Conventional technology]

A lock that retracts the latch head by changing operating members such as a lever or MV ball, and a lock that retracts the deadbolt using only a thumb turn or a thumb turn and a key inserted into a cylinder lock are installed in parallel on the door. It is being

However, if the door is large as shown in Figure 14,
When the manipulating cloth member 3 is gripped, the above-mentioned do cannot be done.

Of course, the same applies to thumb turns and keys.

Therefore, the position of the lock has been changed so that the door stopper cannot be touched.

[Problem that the invention seeks to solve]

It is already known that when installing a lock, the latch head is adjusted so that the protrusion of the latch head is in the normal state as the position changes (to the opposite side of the opening/closing edge of the door) and then the lock is installed.
Since the deadbolt cannot be adjusted, the amount of deadbolt protrusion is reduced, which poses a safety problem.

For safety reasons, if the position of a lock with a deadbolt is not changed, the axes of the locks located above and below will be subcontracted, resulting in an unsightly appearance.

[Means for Solving the Problems] In order to solve the above problems, the present invention provides a lock case, a dead bolt fitted in and out of the lock case, and an end bolt of the lock case. a groove-shaped slider that is fitted into the guide plate so as to be able to move forward and backward with the connecting side located on the lower side; A pair of parallel connecting plates whose tips are rotatably connected to the ends of the slider, and a pair of parallel connecting plates are inserted between the connecting plates, and the lower ends are rotatably attached to both side plates of the slider via shafts. The attached rocking plate and the rocking plate are attached to the guide plate by passing the shaft through it, and by using a window provided so as not to obstruct the sliding of the shaft and the slider in the front and back direction, and a shaft with only a thumb turn or a thumb turn. a square hole provided so that the rotation angle shaft with the cylinder lock fits into the engagement; a fixing device provided to fix the slider to the guide plate at two or more predetermined positions in the front and rear directions; A long hole is provided at the upper end of the connecting plate so that both ends face in the front-rear direction, and a long hole is provided at the upper end of the rocking plate with both ends positioned vertically, and a pin is inserted through the corresponding long hole. A recess is provided on the upper edge of the elongated hole so that the end of the pin fits into the recess with a spacing equal to the interval between the front 1 self-fixing positions, and a rotatability is provided to the connecting plate to prevent the pin from escaping from this recess. The deadbolt is provided with a spring and a notch provided at both ends of the old edge of the side plate of the slider so that the end of the pin fits into it when the deadbolt is extended and retracted.

[Effect]

When the swing plate is rotated in one direction along with the shaft by a thumb turn or a rotation operation of the key inserted into the cylinder lock, the connecting plate is moved forward through the pin fitted and locked in the recess, so the deadbolt protrudes. .

In addition, when the rocking plate is rotated in the direction of the shaft together with the shaft, the connecting plate is moved back through the pin that is fitted into the recess and locked.
The deadbolt is immersed.

Next, when changing the position of the shaft in the opposite direction of the lock case, pull up the end of the connecting plate to allow the pin to escape from the recess into the elongated hole, and then move the slider backward while moving the connecting plate forward. The pins are aligned with the four portions at positions equal to the amount, and the recesses are fitted into the pins to engage them.

After that, the fixation by the fixing device is released, and then the slider is slid in the opposite direction of the rule case, and the slider is stopped at a position equal to the amount of advance of the connecting plate, and then fixed by the fixing device.

When operated as described above, the connecting plate is advanced by the amount by which the position of the shaft is changed, so that the amount of protrusion of the deadbolt is always constant. .
