The retainer apparatus includes the first retainer portion configured to be slidably attached to a first harness strap and a second retainer portion configured to be slidably attached to a second harness strap. The first retainer portion is removably attached to the second retainer portion. The motion detector is configured to detect movement of the retainer apparatus and activate the alarm to alert a user in a vehicle if movement of the retainer apparatus is detected.

A retainer apparatus including a first retainer portion, a second retainer portion, a transceiver, and a sensor comprising a motion detector. The retainer apparatus includes the first retainer portion configured to be slidably attached to a first harness strap and a second retainer portion configured to be slidably attached to a second harness strap. The first retainer portion is removably attached to the second retainer portion. The motion detector is configured to detect movement of the retainer apparatus and transmit a warning signal, via the transceiver, to a controller within a vehicle comprising the retainer apparatus to alert a user in the vehicle if the movement is detected.

A buckle assembly may include a first connection member, and a second connection member configured to receive at least a portion of the first connection member in order to removably connect the first connection member to the second connection member. The second connection member includes an outer frame defining a central opening that is configured to allow monitoring of alignment and connection between the first and second connection members.

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.

Two slab bolster elements having rails supported on legs for carrying rebar during casting are connected end to end by a blade for sliding longitudinally of the rail into a female receptacle and a releasable locking mechanism which acts to lock the blade in the female receptacle. The locking mechanism comprises a notch on one side surface of the blade and a projecting portion of the female receptacle engaged into the notch. The projecting portion is carried on the female receptacle by a portion which can flex to cause the projecting portion to move away from the side surface of the blade. The female receptacle includes a manually depressible member on a side of the female receptacle opposite the projecting portion which when depressed provides motion toward the female receptacle which causes the projecting portion to move out of the notch.

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 connector arrangement joining a respiratory mask and headgear is adapted for single-handed disengagement by the patient. A first, rigid connector part is formed into the rigid mask frame, with a mating second connector attached to a strap of the headgear. The connectors are held away from the patient's face by the connection to the mask frame.

A quick-release connecting assembly, including a spring core and a socket, said spring core including a sleeve-connected elastic portion and a clamping boss set on said sleeve-connected elastic portion; one end of said socket is opened to form a hole adapted to receive the spring core plugged into and a hole wall surrounding said hole. A clamping slot is adapted to receive said clamping boss formed in said hole wall, said slot determining an abutment edge for abutting the clamping boss. A push member is located in correspondence to said clamping boss and is set on the socket at the clamping slot, said sleeve-connected elastic portion being arranged to elastically engage the clamping boss with the abutment edge when the sleeve-connected elastic portion of the spring core is plugged into the hole of the socket.
