An interchangeable electro-mechanical lock core for use with a lock device having a locked state and an unlocked state is disclosed. The interchangeable electromechanical lock core may include a moveable plug having a first position relative to a lock core body which corresponds to the lock device being in the locked state and a second position relative to a lock core body which corresponds to the lock device being in the unlocked state.

A tubular lock for push locking has a lock housing, a switching handle mounted in a front end portion of the lock housing, an upper pin seat and a lower pin seat mounted in the lock housing and the switching handle, and multiple pin assemblies and a core shaft mounted in the upper pin seat and the lower pin seat. A key is only needed when unlocking the tubular lock, and then the tubular lock can be locked by pushing the core shaft. The tubular lock can be used to latch a pivotal mechanism. When the tubular lock is in an unlocking state, the user can switch the latch to the locking angular position or an unlocking angular position by turning the switching handle without using the key. Therefore, flexibility and convenience in using the tubular lock can be efficiently improved.

The present disclosure is directed to a lock assembly that can be converted between a clutching and non-clutching orientation by rotating an outer housing 180 degrees relative, to an outside drive assembly. The outer housing includes a notch and an elongate arcuate slot formed in the inner surface of the outer housing adjacent a through aperture and across from one another. A lock control lug is moveably coupled with the outside drive assembly and is selectively engageable with the notch or the arcuate slot of the outer housing. An outer lever is placed in a non-clutching configuration when the lock control lug is engaged with the notch and in a clutching configuration when the lock control lug is engaged with the arcuate slot.

Described is a handle assembly (10) with lock (100), particularly for a glass leaf (200), which comprises a first fastening member (11), having a first abutment face (12) designed to make contact with a first face (201) of a leaf (200), a second fastening member (13) and connecting means (15) for mutually connecting the fastening means (11, 13).

The first fastening member (11) comprises: a casing (17) equipped with an operating opening (18); a housing (19) for a cylinder (101) of the lock (100) and equipped with locking means (21) for blocking the cylinder (101) and facing the operating opening (18) for being actuated through the latter; a closing element (22) movable with respect to the housing (19) between an open position and a closed position in contrast with elastic means (23).

In the closed position of the closing element (22) it is interposed between the operating position (18) and the locking means (21) and in the open position the closing element (22) protrudes from the first abutment face (12) and it is not interposed between the operating opening (18) and the locking means (21) for allowing the actuation of the latter from the outside of the casing (17).

An interchangeable electro-mechanical lock core for use with a lock device having a locked state and an unlocked state is disclosed. The interchangeable electromechanical lock core may include a moveable plug having a first position relative to a lock core body which corresponds to the lock device being in the locked state and a second position relative to a lock core body which corresponds to the lock device being in the unlocked state.

A door lock actuation device configured for operating a door lock in a door blade, wherein the door lock includes a dead bolt driven by rotation of a connector is provided. The device includes a casing, inside which there is provided a motor for driving a rotational connector-receiver that receives and rotates the connector. The device also includes a rotational handle mechanically connected to the connector-receiver, for forcing rotation of the connector-receiver by manual rotation of the handle. The motor is selectively disconnectable from the connector-receiver for manual driving of the connector-receiver by the handle without backdriving the motor.

A cylinder lock assembly for forming a cylinder lock for attachment in a panel, such as, for example, a door, includes an inner lock housing part, an outer lock housing part, at least one bridge, a carrier, an outer cylinder, an inner cylinder, a carrier coupling, an operating knob, and a set of lock housing extension parts. The cylinder lock includes a selection from the set of the lock housing extension parts connected with the inner lock housing part in order to obtain a desired length of the inner lock housing part with the lock housing extension parts. This desired length is adaptable by changing the number of lock housing extension parts within the selection and/or selecting a lock housing extension part of a desired thickness. The selection from the set of the lock housing extension parts is positioned between the inner lock housing part and the operating knob.

According to a first aspect of the invention, there is provided a doorknob (108) with a fixing mechanism (100) comprising at least a first locking member (102A) and at least a first spring element (104A) coupled with the first locking member (102A), wherein the spring element (104A) is configured to move the locking member (102A) to be in contact with a lock cylinder (106) to prevent movement of the doorknob in relation to the lock cylinder (106) in a longitudinal direction (CL). According to a second aspect of the invention, there is provided a lock arrangement comprising the doorknob (108) with a fixing mechanism (100) and the lock cylinder (106). According to a third aspect of the invention, there is provided an opening tool (110) for the doorknob (108) with the fixing mechanism (100).

A cylinder lock 1 for use with a lock assembly 10. More specifically the cylinder lock is of the kind including a cam 5 rotatable from one side by a hand turn means 4, and an opposed side by a key controlled barrel 3. The configuration of the first side of the cam 5 so as to inhibit the interaction with the barrel 3 provides a useful result.
