Abstract: A plug-in connector has two pushbuttons arranged laterally thereon. An annular, asymmetric spiral spring is inserted in such a manner that the spiral spring, in its locking orientation, permits the respective pushbutton pin to move into the plug-in connector housing and prevents the pushbutton pin from moving out of the plug-in connector housing. The spiral spring can tilt from its locking orientation into its release orientation when arranged with its inner region in a release groove of the pushbutton pin. In its release orientation, the spiral spring permits the pushbutton pin to move out of the plug-in connector housing. This permits actuation similar to a ballpoint pen with only a few components and with high operating comfort.

Abstract: A locking mechanism for first and second housing parts of a housing of a plug connector, includes a push button, which extends in the axial longitudinal direction through an opening of the first housing part into the interior of the housing. The push button is movably arranged, relative to the housing, between predetermined first and second axial positions, which correspond with the first and second positions of the housing parts. The push button and an interior locking element are configured such that the push button is in pressure contact to the locking element and interacts with the locking element such that, in the case of movement of the push button from the first to the second positions a radial pressure contact between the two housing parts is provided such that a gap between the first and second housing parts is minimized.

Abstract: The present disclosure is directed to a combination lock including a housing configured to lockingly receive a locking link. The lock includes a plurality of outer dials and a plurality of inner dials, each selectively coupled to a corresponding outer dial. A spindle is positioned radially internal to the inner dials. A multiplier link is pivotably connected between the spindle and a locking bolt. Some forms of the combination lock include a tactile feedback mechanism and/or a combination reset mechanism.

Abstract: A combination operated padlock has indicia carrying dials that are turned to set a combination for unlocking a shackle of the padlock. Operating components of the padlock are carried by or within a housing-enclosed frame of the padlock. A strong, corrosion resistant insert, preferably formed from brass of uniform thickness, is configured to fit cleverly around and among the movable operating components to strengthen the padlock and to prevent operating component manipulation if an unauthorized unlocking of the padlock is attempted. In a preferred embodiment, the insert has two substantially identical question-mark-shaped tines configured to extend toward and between different adjacent pairs of the dials that are turned to set a combination.

Abstract: By providing a single housing and shackle assembly constructed for enabling the shackle to be opened and/or closed using either a rotatable dial combination construction or a key activating tumbler construction, with the movement of the shackle being controlled by a trigger member, an effective, easily produced, padlock is achieved which incorporates two separate and independent locking systems formed in a single padlock. In addition, the trigger member and shackle each incorporate uniquely constructed, cooperating surfaces, each of which comprise a grooved zone or concave curved zone which is positioned directly adjacent a cooperating convexly curved zone. By employing these two curved surfaces on both the shackle and trigger member, the controlled pivotal movement of the shackle is realized.

Abstract: A padlock comprises a shackle having a first end and a second end and an arm, the arm being extendable along an axis of the arm. The arm further includes a locking mechanism having an axle pivotally connected to the second end and a plurality of tumblers sleeved into the axle, in which the axle defines an inner channel; and a movable connection component having a head and a shaft connected to the head, and when the locking mechanism is in a first position, the head is attached to the first end and when the locking mechanism is in a second position, only the movable connection component is movable along the axis of the arm and the head is detached from the first end.

Abstract: A padlock with a status indicator includes two locking units. The two locking units operate independently to execute locking and unlocking operations. The lock has a body that contains an indicator in the lock underneath. After the execution of the unlocking operation has been done sequentially, the indicator switches from an indication position to the other indication position. Thus through the window, which is formed on the body surface and corresponding to the indicator location, the indication positions of the indicator may be recognized.

Abstract: Provided is a combined combination lock and padlock comprising a second shackle receiving hole including an inside slot at one leg of a shackle of steel rope for receiving a spring depressible block, a tumbler wheel assembly, a key turning assembly, a pivot assembly, a push button, and a U-shaped shackle, A correct combination of tumblers and a subsequent pressing of the push button will disengage a dog with the slot and thus expansion of the block will push the leg out of engagement with the lock. Should either the combination be forgotten or the combination be changed by another person, a turning of the shaft about 90 degrees by inserting a key into the keyhole will turn the projection and the engaged engagement member for releasing the dog.

Abstract: A combination lock comprises a first shackle, dials, a spring loaded member biased against the innermost dial, a second shackle comprising an inner arm, a moveable block pivotably coupled to the inner arm and including a spring and an opposite T-shaped slot, and a key opening mechanism aligned with the moveable block and comprising a shaft and a cross member. Inserting a key into the mechanism and turning the key will rotate the shaft and the cross member until the cross member is aligned with an opening of the slot such that pressing the second shackle will cause the inner arm to counterclockwise pivot about the member, move the moveable block outwards to compress the spring and dispose the cross member in the opening, and disengage the second shackle from the first shackle.

Abstract: A combination lock comprises a tumbler wheel assembly, a backup locking assembly comprising a keyhole, a shaft, and an inner projection having a half circular section, a pivot assembly having a dog and an engagement member, a push button secured to the pivot assembly, a U-shaped shackle pivotably fastened at the lock housing, and an L-shaped resilient member. A correct combination of tumblers and a subsequent pressing of the push button will disengage the dog from a slot at one leg of the shackle and thus exert an elastic force of the resilient member on the leg for pushing the leg out of engagement with the lock. Should either the combination be forgotten or the combination be changed by another person, a turning of the shaft about 90 degrees by inserting a key into the keyhole will turn the projection and the engaged engagement member for releasing the dog.

Abstract: Padlocks adapted for one-handed operation are disclosed. Typically having a laterally asymmetric shackle, the lock includes an arm connected thereto so as to pivot when the locking mechanism is disengaged. A spring or other component facilitates latching of the device by biasing the arm toward an exposed end of the shackle.

Abstract: An intravenous pole clamp contains a locking mechanism which employs a spring clutch. The clamp body has an attachment for a medical device and a chamber for receiving an I-V pole. A threaded stud is rotated inwardly to clamp the I-V pole. A spring having one fixed end and one free end is threaded onto the shaft of the threaded stud. A locking mechanism allows the free end of the spring to be unrestrained in a locked position. When unlocked, a pin of the locking mechanism slightly unwinds and restrains the free end of the spring freeing the threaded stud to rotate in either an inward or an outward direction. In a locked position, the threaded stud can rotate inwardly but if it is attempted to rotate it outwardly the spring clutches the threaded stud preventing outward rotation.

Abstract: A conventional barrel-type combination lock receives a lock element extending from a safety pin housing. The safety pin housing pivotally receives a pin that pivots between an open position and a closed position relative to the safety pin housing, and the lock element of the barrel-type combination lock is moved to the locked position, the end of the pin is positioned within a pin receiving recess on the barrel-type combination lock so that the pin is locked in the closed position. A conventional chain formed from a series of interlocking links is utilized with the lockable safety pin to enable small articles to be locked to fixed objects. When the chain is not in use, it is stored within a cylindrical chain storage container that is threadedly received upon the end of the barrel-type combination lock.
