Hospital gas cylinder trolley with semirigid securing straps

A mobile trolley (1) comprising:

• a baseplate (2) configured to accommodate at least one gas cylinder (50), several castors (3) for moving the trolley along the ground, a support structure (4) projecting upwards from the baseplate (2), and at least one securing device (30) arranged on the support structure (4) for securing said at least one gas cylinder (50) to said support structure (4),
• wherein said at least one securing device (30) comprises a first strap element (31) comprising a free first end (31.1), and a second strap element (32) comprising a connecting device (20), said first strap element (31) connecting with the second strap element (32) to allow the first strap element and the second strap element to be secured to one another when the free first end (31.1) of the first strap element (31) is connected with the connecting device (20) of the second strap element (32),
• wherein the first strap element (31) and second strap element (32) are made of semirigid polymer, and
• the connecting device (20) of the second strap element (32) comprises:
• a main body (21) through which passes an internal passage (22) extending between an entrance (22.1) and an exit (22.2) and which is configured to accommodate at least part of the first strap element (31),
• immobilizing means (23) capable of moving between at least two positions, comprising:
• an immobilizing position in which the immobilizing means (23) connects with a relief textured region (310) of the first strap element (31) inserted into the internal passage (21), so as to prevent and oppose any withdrawal movement of said first strap element (31) from the internal passage (21), and
• a releasing position in which the immobilizing means (23) allow withdrawal movement of the first strap element (31) from the internal passage (21),
• release means (24), capable of being actuated by a user, connecting with the immobilizing means (23) in order to cause the immobilizing means to pass from the immobilizing position to the releasing position, when actuated by the user, and
• tightening means (250), capable of being actuated by the user, configured to connect with the relief textured region (310) of the first strap element (31), when the first strap element (31) is inserted into the internal passage (21) of the connecting device (20) of the second strap element (32) and
• wherein when also the immobilizing means (23) are in the immobilizing position, when they are actuated by the user, the tightening means (250) cause the first strap element (31) to progress translationally within the internal passage (21) of the connecting device (20), in the direction of insertion.
