Provided is a closure device including a first closure part that includes a locking element, a force transmission element operatively connected to the locking element, which can be loaded along a force direction, and an actuating element movable relative to the locking element, and a second closure part that includes an engagement element. The locking element and the engagement element can be attached to each other for connecting the first closure part and the second closure part to each other and are connected to each other in a closed position. In the closed position, when the force transmission element is loaded along the force direction, the locking element is loaded in a locking direction towards contact with the engagement element by the action of force of the force transmission element. The actuating element can be actuated in order to adjust the locking element against the locking direction.

A wearable electronic device assembly has a strap attached to the device for attaching the device to a wearer, and a connector for securing two overlapping end regions of the strap together. The connector has first and second parts configured to be secured together with the two overlapping end regions of the strap extending between them, to secure the two end regions together. The first part has a projection arranged to extend through or adjacent to the strap. The second part has a main body having an aperture to receive the projection of the first part, and a securement part movable with respect to the main body between a released position and a securement position. The projection is retained in the aperture to secure the first part of the connector to the second part of the connector.

A belt buckle includes: an elastic member, a female buckle and a male buckle connected with different ends of lace. The female buckle includes a base provide with an insertion slot and a cover plate provided with a protrusion. The cover plate is mounted on the base and rotatable relative to the base. The male buckle includes an insertion block provided with a recess and a male buckle main body connected to the insertion block. When the insertion block is inserted into the insertion slot, and the protrusion extends into the recess, the female buckle and the male buckle are fastened together. When the cover plate is pressed to move towards the base, the elastic member press the cover plate to lift the cover plate in the direction away from the base to cause the protrusion to separate from the recess.

A back support device for supporting a lower back of a user may include an elastic strap, a first clasping element attached to a first end of the elastic strap, a second clasping element slidably disposed over the elastic strap and configured to releasably engage the first clasping element to form a continuous loop, and a buckle element secured to a second end of the elastic strap. The buckle element is slidably disposed on a medial portion of the elastic strap for adjusting a perimeter length of the continuous loop. The continuous loop is movable between a first position in which the continuous loop has a first perimeter length and a second position in which the continuous loop has a second perimeter length via elastic elongation. The first perimeter length is less than the second perimeter length.

A magnetic buckling assembly includes a male buckling component, a female buckling component, a first locking portion, a second locking portion, an operating component, a first magnetic component, a second magnetic component and a clearance structure. The first magnetic component magnetically attracts the second magnetic component for preventing separation of the male buckling component and the female buckling component or magnetically repulses the second magnetic component for promoting the separation of the male buckling component and the female buckling component when the operating component is operated to disengage the first locking portion from the second locking portion for allowing the separation of the male buckling component and the female buckling component. The clearance structure allows the second locking portion to slide an offsetting position for preventing the separation of the male buckling component and the female buckling component after engagement of the first locking portion and the second locking portion.

The connector has first and second parts configured to be secured together with the two overlapping end regions of the strap extending between them, to secure the two end regions together. The first part has a projection arranged to extend through or adjacent to the strap. The second part has a main body having an aperture to receive the projection of the first part, and a securement part movable with respect to the main body between a released position and a securement position. The projection is retained in the aperture to secure the first part of the connector to the second part of the connector.

The present invention relates to a device for connecting straps, objects or portions of garments and accessories forming a quick-snap buckle. The device according to the invention comprises, in accordance with a first feature, two strictly identical and complementary parts, such that said parts may be combined to thus form a single assembly. To achieve said assembly, said parts have a main body provided with two or three parallel lobes (2-5) that are flat and curved portions that fit into one another, wherein said lobes have circular movable members that bend in order to lock the device, for the male portion of said members, and circular movable members that bend and are equivalent to push buttons (6) to release the device, for the female portion of said members. The architecture and the mode of connection of the parts make it possible to assemble not just two parts, but also three, four, five parts or more, and simultaneously make it possible to work with special functionalities or specific strap shapes.

Embodiments are directed toward a latch. The latch preferably has a housing that defines a receiver channel that is configured to receive a latchable member. The latch preferably has a catch that is transitionable between an open configuration and a closed configuration. In the open configuration, the catch is preferably configured to enable insertion and removal of the latchable member into and from the receiver channel. In the closed configuration, the catch is preferably configured to at least partially close the receiver channel and to prevent removal of the latchable member from the receiver channel.

A wearable electronic device assembly has a strap attached to the device for attaching the device to a wearer, and a connector for securing two overlapping end regions of the strap together. The connector has first and second parts configured to be secured together with the two overlapping end regions of the strap extending between them, to secure the two end regions together. The first part has a projection arranged to extend through or adjacent to the strap. The second part has a main body having an aperture to receive the projection of the first part, and a securement part movable with respect to the main body between a released position and a securement position. The projection is retained in the aperture to secure the first part of the connector to the second part of the connector.

Embodiments of the present disclosure provide a locking assembly for an attachment system of a consumer product. More specifically, embodiments of the present disclosure are directed to an attachment unit that is configured to be inserted and removed from a housing of a consumer product. The attachment unit and/or the housing include an expansion component or other such locking assembly configured to releasably secure the attachment unit within the housing.
