Aspects of the present disclosure may relate to a bag having a retractable lock unit that may simultaneously prevent theft of the bag and theft of its contents. The bag may include the retractable lock unit which can be secured to the bag, a zipper system having a pair of zippers, and a locking ring. In some aspects, a user may draw the lock unit from its housing to the pair of zippers and lock the pair of zippers together so as to prevent the bag from being opened. In this way, the bag may provide additional security for the contents while the user has the bag on their person or near themselves. In other aspects, the user may draw the lock unit from its housing around one or more objects before securing it to the locking point and/or a pair of zippers. In this way, the bag may be securely anchored to the one or more objects thus preventing theft of the bag itself as well as preventing theft of the contents.

A novel security tether includes an intermediate flexible substrate, a first loop, and a second loop. The first loop is fixed to a first end of the intermediate flexible substrate and is switchable between a closed position and an open position. The first loop further includes a lock to retain the first loop in the closed position when engaged. The second loop is a fixed, closed loop that is coupled to a second end of the intermediate flexible substrate and is configured to allow the first loop to pass therethrough to create a secondary loop to encircle an anchor object. The first loop can be closed around an object to be secured, thereby securing the object to be secured to the anchor object when the lock is engaged. The security tether is conveniently portable and particularly useful for securing skis to an anchor object.

A lockable enclosure includes a housing and an access door assembled with the housing and movable between a closed position and an open position. A latch is carried by the access door and is slideable along a first axis between a door latching and a door releasing position. A plurality of dials are carried by the access door and rotatable about a post extending along a second axis. When each of the plurality of dials is rotated to an unlocking orientation, an outer peripheral recess on each of the dials aligns with a corresponding dial engaging portion of the latch, allowing the latch to slide along the first axis from the door latching position to the door releasing position.

Disclosed is an improved password lock, comprising a housing, a lock case, a password box, and a tongue; the housing is composed of a shell and a panel; the panel is fixed on the top surface of the shell to form an accommodating cavity of the housing; the middle part of the lock case is rotatably sleeved at one side of the housing; the password box is installed in the accommodating cavity of the housing, and the password box is cooperatively linked with the lock case; and the tongue is fixedly sleeved on a penetrating end, penetrating through the housing, of the lock case. The lock case can drive a slide block in the password box to move horizontally for changing a password, and therefore the operation is convenient.

A locking pin includes a body having a plurality of apertures defined through a sidewall. A closure is disposed at an end of the body. A plurality of latch bolts is disposed in the body and adjacent to the closure. Each latch bolt is moveable through a corresponding one of the apertures and between a locked position, disposed at least partially outside of the body, and an unlocked position, disposed at least substantially within the body. A keeper is coupled to each of the latch bolts and configured to retain the latch bolt in the latched position and to bias the latch bolt for movement from the locked position to the unlocked position. A mechanism selectably engages each latch bolt to move the latch bolt to the locked position, and selectably disengages from the latch bolt to allow the keeper to move the latch bolt to the unlocked position.

A method of an optical sensor apparatus which is to be used with a controlling device arranged for controlling an object having a long shape and flexible form of a material, includes: using a light emitting circuit to generate and output a light ray to a surface of a portion of the object; sensing the light ray reflected from the surface for multiple times to generate multiple images; detecting at least one motion image in the generated multiple images; and, determining a motion, an offset, or a rotation angle of the object, which is controlled by the thread controlling device, according to the detected at least one motion image.

A door lock has an inner door assembly, an indoor doorknob assembly, and an outdoor doorknob assembly. The inner door assembly has a locking assembly casing. The indoor doorknob assembly has a positioning resilient component located in the locking assembly casing and configured to switch the door lock between a locked state and an unlocked state. The door is provided with enhanced protection by enclosing the positioning resilient component in the locking assembly casing, so the safety is further improved.

A luggage zipper lock and a luggage, including a lock and a zipper, wherein the zipper includes a slider and a puller, the puller being provided on the slider, a first end of the slider is provided with a locking portion corresponding to the lock; when in a locked state, the locking portion on the slider is inserted into the lock and locked; when in an unlocked state, the lock is unlocked, and the locking portion on the slider can be pulled out from the lock. By moving the locked portion from the puller to the slider, the function of locking by pulling the slider is realized, which is simpler as compared to locking by buckling the puller into a lock hook, and the locking portion corresponds to the lock, so that only the zipper is pulled without making mistakes.
