## Abstract

Gas supply device comprising a frame (2) housing a set of pressurized-fluid cylinders (3) linked to a fluid circuit (4, 5) for filling and emptying the cylinders (3), the support frame (2) comprising a lower base (34) on which the cylinders (3) rest vertically and a set of uprights (30) and cross beams (31, 32, 33) forming a cage with an overall parallelepiped shape to provide lateral support for the cylinders (3) arranged in several contiguous rows, characterized in that it includes at least one rigid reinforcement bar (6) for the frame (2) arranged between two rows of contiguous cylinders (3), said at least one reinforcement bar (6) resting simultaneously on the upper surface of the cylinders (3) in two rows of adjacent cylinders (3), the reinforcement bar (6) having two extremities connected rigidly and respectively to two opposing faces of the frame (2).

## Claims

### Claim 1

A gas supply device comprising a frame housing a set of pressurized-fluid cylinders linked to a fluid circuit for filling and emptying the cylinders, the frame comprising a lower base on which the cylinders rest vertically and a set of uprights and cross beams forming a cage with an overall parallelepiped shape to provide lateral support for the cylinders arranged in several contiguous rows, the device including at least one rigid reinforcement bar for the frame arranged between two rows of contiguous cylinders, said at least one reinforcement bar resting simultaneously on the upper surface of the cylinders in two rows of adjacent cylinders, the reinforcement bar having two extremities connected rigidly and respectively to two opposing faces of the frame, wherein the at least one reinforcement bar rests against the cylinders to generate a vertical force on the cylinders oriented towards the base, the two extremities of the reinforcement bar being connected rigidly and respectively to the base and/or to two cross beams of the frame located respectively on two opposing faces of the frame, and in that the device includes upper corner reinforcing members arranged respectively at the joins between the extremities of the cross beams delimiting the upper extremity of the frame on the one hand, and the related adjacent uprights on the other, the upper reinforcing corner members being rigid and having two extremities connected rigidly and respectively to a cross beam and to the adjacent upright, further comprising a face delimited by said uprights having a vertical length that is less than the length of the vertical uprights of an opposing face, such that the face delimited by the uprights is higher than the opposite face.

### Claim 2 (depends on 1)

The device of claim 1, wherein the at least one reinforcement bar is parallel to said faces of the frame of different heights.
