The subject matter of the invention are various methods, systems and devices and the ways of their installation/fitting/assembly of emergency opening of manholes (entry openings) or loading holes (door) in emergency situations, especially an emergency move/shift of movable components closing manholes (entry openings), exit openings, loading or unloading openings, from closed position into opened position, such as doors, manholes, hatches, gates, emergency exits, windows, window panes and other, especially in means of transport, construction furnishing devices and premises (buildings). The invention is connected with the use of pyrotechnic actuators which can be telescopic actuators, piston actuators or flexible ones, driven with propelling actuating agents which are in the form of gas generators, pressure of compressed gas or air, compressed air from a compressor or a material with shape memory.

The present disclosure relates to the technical field of lock, especially to the lock device for locking the sliding door. The lock device comprises a first lock portion and a transmission portion. The transmission portion may move along relative to the first lock portion a predetermined path, so that the transmission portion may bring the sliding door to move along the predetermined path to open or close the sliding door. The transmission portion has a plurality of successively arranged mating portions for locking with the first lock portion. The first lock portion has a first position in which the first lock portion is locked with the transmission portion and a second position in which the first lock portion is released from the transmission portion. The transmission portion may be locked in different positions along the predetermined path by matching the first lock portion (110) with different mating portions, so that the sliding door can be locked in different positions. Through the technical solution mentioned above, the sliding door may be locked not only in a fully open position or a fully closed position of the sliding door, but also in any partly-open position of the sliding door, so that the sliding door maybe locked in the partly-open state stably.

A fastening arrangement for fastening a vehicle sliding door to a vehicle body while enabling opening and closing of the sliding door. The fastening arrangement includes a motion element configured for being movingly arranged within or on a vehicle body guiding rail for enabling movement of the motion element along the vehicle body guiding rail, and a variable-length motion mechanism connected to the motion element and configured for being fastened to the sliding door at a lower attachment area of the sliding door. The variable-length motion mechanism is configured for enabling variable distance between the motion element and the lower attachment area of the sliding door.

A device for the sliding movement of doors and wardrobe doors (12) provided with at least two doors (14,16) or (62, 64, 66) sliding so as to move along respective and parallel guides (18) and (18) fixed near the front edge of the upper base (20, 60) of said wardrobe, comprising: at least one pair of carriages (22), provided with at least one wheel or roller (32), fixed to the inner front of each door (14) and (16) at or near the respective upper edge; a plate-like element (22) for the direct attachment of at least one of the carriages (22) to the doors (14) or (16); at least one frame with an inverted U cross-section (46), and/or (46) supporting a wheel or roller (32); opposite air pistons (24) fixed to the end of the guides (18) along which the wheels or rollers (32) of the carriages (22) slide for the cushioned stop at the end stroke upon closing and opening of said carriages, and thus of the doors (14) and (16). Said device comprises a support (30) housing a piston (40) surmounted by an integral pincer or elastic clamp (44), said support (30) is fixed to at least one of the frames with an inverted U cross-section (46) or (46).

An apparatus is provided for moving and securing articles in a pickup truck cargo bed. The pickup truck cargo bed may have opposing sidewalls, cab wall, tailgate, and floor. The apparatus comprises a plurality of tracks configured to connect to the pickup truck cargo bed, the plurality of tracks extending substantially along a longitudinal length of the pickup truck cab and defining a channel. A push plate slidably is mounted to the plurality of tracks with a movement member, and the push plate configured to stand perpendicular to the floor.
