Abstract
The lock with knobs and bolt operating with a spring and key is suitable for fitting to the doors of offices, hotels, communities, etc. and preferably for fitting to doors where opening and closing of the door is frequent and is normally performed by a spring bolt operated by internal and/or external handles. By the direct operation of a handle or by operation of a knob after enablement by a "key-operated lock" fitted to the handle itself, the bolt is caused to perform a stroke increasing the stroke with respect to the spring. The lock described by the invention then passes from spring operation to rigid bolt operation and vice versa. The lock with knobs and bolt operating with a spring and key is built to be the same size and shape as the previous lock with knobs so that it can be fitted without difficulty to existing doors to replace the lock with knobs presently fitted.
