A buckle with an enhanced efficiency in removing a foreign substance is provided. The buckle includes: a plug; and a socket provided with an insertion opening into which the plug is to be inserted. The socket includes: a pair of front pieces disposed side by side in a width direction intersecting with an insertion direction of the plug; a back piece disposed to face each of the front pieces; and a bottom piece that connects each of the front pieces and the back piece. A slit defined between the pair of front pieces extends in the insertion direction from the insertion opening across the bottom piece and the front pieces of the socket. Due to the presence of the slit, a cross section of the socket intersecting with the insertion direction is in a C-shape.

A buckle assembly structured for quick release and including a gripping assembly structured to removably retain an end connector in a locked position. Two locking segments are movably connected to one another and disposable between a closed orientation and a release orientation. The locked position includes the locking segments disposed in gripping engagement with the connector when the connector is disposed between the locking segments. A quick release assembly may be selectively positioned into a separating engagement with the locking segments to at least partially define a positioning thereof from their closed orientation into their release orientation. A secondary release assembly is connected to the gripping assembly and is independently operable to release the connector from the gripping engagement with the locking segments.

A base frame (34) which is universally usable for different modular structured conveying vehicles (30), in particular for shuttles (32), wherein the conveying vehicles (30) can travel horizontally along a travelling direction (52) in a storage and order-picking system (10), wherein the base frame (34) comprises a supporting frame (36) and a structure (38) connected to the frame (36), wherein at least the structure (38) is made of plastic only, and wherein the structure (38) comprises a plurality of component-specific seatings (58) being formed integrally with the structure (38) and being configured to positively hold in a resilient clamp at least one of the following functional components (60) of the respective conveying vehicle (30): a bearing (62); a driving unit (64); a sensor (66); an actuator (68); a load-handling device (70); a communication unit (78); a cabling (76); and an electric controlling unit (80) wherein each of the functional components (60) is positively insertable in or on the respective component-specific seating (58) along a component-specific mounting direction.

A buckle includes a male member including a base part and a pair of flexible arms extending from the base part, and a female member including an insertion hole formed at one end portion thereof. The pair of flexible arms is inserted in the insertion hole. The base part contacts the one end portion when the male member engages the female member. An outer face portion of each of the pair of flexible arms has a shape curving outwardly at a middle portion thereof relative to an insertion direction of the pair of flexible arms, and the pair of flexible arms is provisionally fastened to the female member when the pair of flexible arm is inserted in the insertion hole.

A closure device is provided. The closure device includes a first closure element, a second closure element, which can be arranged on the first closure element in a fixing direction and which is connected to the first closure element in a closed state, and at least one actuating element, which is movably arranged on the second closure element. The at least one of the closure elements has a receptacle into which the other closure element can be shoved at least partially. The second closure element in the closed state is held on the first closure element via the actuating element and for this the second closure element interacts with the actuating element, while in an unloaded state the second closure element can be loosened from the first closure element by activating of the actuating element.

A safety buckle device includes a first buckle part having a partially closed space with an opening, and a second buckle part having a body, a guiding tongue, and a control key. When locking the safety buckle device, a springing detent is adapted to lock against a locking element. The control key has two recesses having different depths and arranged adjacent each other in the longitudinal direction of the control key. The detent achieves a first locking when the control key is actuated, and the detent achieves a second locking when the control key no longer is actuated, or the detent achieves a locking when the control key is not actuated. The detent is adapted to be released when the control key is actuated again, or when the control key is actuated.

A side release buckle includes: a plug; and a socket, the plug including: a base; a pair of legs; and engaging portions, the socket including: a body; an insertion opening; a housing space; engaged portions; and a pair of guide surfaces. The guide surfaces, which are formed on an inner surface of the housing space and extend in an insertion direction of the legs while being opposed to each other, each include: a squeezing portion formed continuously with corresponding one of the engaged portions; and a guiding portion formed between the squeezing portion and the insertion opening. An interval between the guiding portions-near the engaged portions is wider than an interval between the squeezing portions near the engaged portions. An inclination angle of each guiding portion to an insertion direction of the plug is smaller than an inclination angle of each of the squeezing portion to the insertion direction.

A buckle which includes a socket and a plug. The socket includes: a cylindrical main body; a hollow part formed within the main body; a pair of left and right openings continuous to the hollow part and penetrating through wall parts of the main body; and a pair of left and right first latch surfaces defined on opening-side wall surfaces of the wall parts of the main body and inclined in a direction intersecting with an insertion direction of the plug. The plug includes: a base; arms; and a pair of left and right second latch surfaces protruding outward from outer sides of the arms and inclined in the direction intersecting with the insertion direction of the plug.
