Detailed description of the invention

Gas bottle (10) comprising a cylinder (11) and a collar

The invention defines a gas cylinder (10) comprising a cylinder (11) with a gas container liner (12). The gas container lining (12) in turn comprises a flap bridge (14) to carry ^{said lining (} 12 ^{) being held in the hand from a set of handles (} 2 ^{) of a collar (} 1 ^{) mounted} on the same.

Figure 1 shows a gas cylinder (10) comprising a cylinder (11) and a collar (1) mounted thereon. In turn, the cylinder (11) comprises a base ring (13) and a gas container lining (12). The gas container liner (12) comprises an upper hemisphere with a flap bridge (14) with a flat plate (14.1) and a lower hemisphere that rests on and is attached to the base ring (13).

The flap bridge (14) with the flat plate (14.1) (not shown in Figure 1) is the so-called vertically inverted L-shaped flap bridge placed on the upper hemisphere of the gas container liner (12). In a preferred embodiment, the cylinder (11) is a cylinder of light carbon steel metal alloy.

The base ring (13) of the gas container liner (12) is a large foot ring and provides a stable attachment for the entire gas cylinder when upright, as well as an additional ^{full diameter handle at the bottom end of the gas cylinder. the gas bottle. (} 10 ^{) to facilitate manual transport.}

In addition, the base ring (13) is conductive, thus guaranteeing a conductive path to ground. Consequently, ^{the gas cylinder (} 10 ^{) does not attach any additional non-conductive or conductive part or component to provide such an} electrical function.

The connection between the base ring (13) and the gas container liner (12) is welded in a conventional manner. In addition, the connection between the flap bridge (14) and the liner (12) is also welded in a conventional manner.

A collar (1) adapted to be mounted on a cylinder (11) of a gas bottle (10)

The invention also defines a collar (1) adapted to be mounted on a cylinder (11).

Figure 2 shows an exploded view of an embodiment of the collar (1) adapted to be mounted on a cylinder (11) of a gas bottle (10). The cylinder (11) comprises a gas container liner (12) with a flap bridge (14) to carry such a liner, being held in the hand from a set of ^{handles (} 2 ^{) of the collar (} 1 ^{), where said collar (} 1 ^{) also comprises:}

• a double coupling hook (3) configured to embrace the flap bridge (14) of the lining (12), the double coupling hook (3) comprising:

or an internal coupling (3.1) adapted to engage the flap bridge (14) of the lining (12),

or an external threaded coupling (3.2) comprising a stopping point (3.3); and

^{• a set of handles (} 2 ^{) comprising:}

^{or a mating flange (} 2 ^. 1 ^{), and}

^{or a spring-loaded locking system (} 2 ^. 2 ^);

where the external threaded coupling (3.2) of the double coupling hook (3) is configured to ^{engage the coupling flange ( 2.} 1 ^{) of the set of handles (} 2 ^{), and}

^{where the spring locking system ( 2.} 2 ^{) of the set of handles (} 2 ^{) is configured to lock the coupling flange} (2.1) of the set of handles (2) with the external threaded coupling (3.2) of the coupling hook double (3) by means of a rotating inward sliding movement once the stopping point (3.3) of the external threaded coupling (3.2) is reached.

Figure 2 also shows a detailed view of the components of the collar (1). Briefly, the collar (1) comprises a double coupling hook (3) and a set of handles (2). In addition, the collar (1) may comprise a cover frame (4), preferably a snap-hook cover frame.

As can be seen in Figure 2, the stopping point (3.3) is presented or integrated into a part of the external threaded coupling (3.2) in the form of a through hole. In particular, the stopping point (3.3) occurs at the upper edge of one of the semicircular halves of the double coupling hook.

The integrated security and protection spring-loaded locking system (2.2) is a retractable flap-shaped tab with a suitable perimeter to be inserted into such a through hole (3.3) once reached by the rotary slide-in movement. Consequently, the through hole (3.3) is substantially elongated.

The set of handles (2) shown in Figure 2 comprises at least one integrated handle (2.3), preferably two symmetrical handles (2.3) for comfortable use. Also, the set of handles (2) comprises at least one U-shaped gas line path (2.4), preferably two U-shaped gas line paths or openings (2.4) for gas line clearance.

In addition, the handle assembly (2) defines a smooth surface at the shoulder curve (2.5), enhancing the ^{smooth diameter transition ( 2.} 6 ^{) from the metal liner (} 12 ^{) to the handle assembly (} 2 ^).

Figure 2 also shows a detailed view of the double coupling hook (3), which defines a complete perimeter ring-shaped element. As mentioned, the double coupling hook (3) is made up of two semicircular halves (3.4) joined together at their ends by connecting pins (3.5).

The double coupling hook (3) is called "double" because it comprises two couplings that therefore act as an intermediate link between the set of handles and the lining of the gas container. One of such couplings is the internal coupling (3.1) in the form of a groove with a cross section substantially similar to the plate (14.1) of the flap bridge (14) of the lining (12) to be hooked therein.

The other coupling of the double coupling hook (3) is the external threaded coupling (3.2) which includes a stop point (3.3) intended to engage with the coupling flange (2.1) of the set of handles (2). Engagement occurs by a rotary slide-in movement, preferably in a counter-clockwise direction as opposed to the common screwing and unscrewing movement.

As a result, the stop point (3.3) restricts the ^{anti-clockwise rotary sliding movement of the spring locking system ( 2.2 ) on the handle assembly (} 2 ^), thus locking it. way to the double coupling hook (3).

In addition, the connecting pins (3.5) joined at the ends of the two semicircular halves (3.4) allow them to be joined (3.4) by rotating lateral joint. In this way, it provides flexibility to embrace and hook, within its entire perimeter, the flap plate (14.1) on the covering (12).

Having attached a connecting pin (3.5), it provides a hinge to allow the swivel side to be attached. Once engaged with the metal flap bridge (14), insertion of the other connecting pin (3.5) locks the double coupling hook (3) into a strong and secure full perimeter joint.

The extraction of at least one connecting pin (3.5) allows to disassemble and even replace either the double coupling hook (3) or the set of handles (2) at any time. The use of removable connecting pins (3.5) provides indefinite ability to mount and dismount the double coupling hook (3) ^{from the liner (} 12 ^).

The double coupling hook (3) further comprises a groove (3.6) along its internal wall (3.7). Preferably, the groove (3.6) is continuous along the entire perimeter of the internal wall (3.7) located near the upper edge of the double coupling hook (3). In other words, the groove (3.6) is substantially parallel to the internal coupling (3.1) on the opposite edge of the internal wall (3.7).

Such a groove (3.6) is configured to house at least one notch for snap-fitting (4.3) of the cover frame (4). The cover frame (4) acts as a top cover, protecting and hiding the double coupling hook (3) in order to prevent its manipulation by an unauthorized person.

The at least one snap-fit notch (4.3) is preferably a set of snap-fit notches (4.3) distributed and positioned homogeneously under an upper peripheral projection (4.2). In this way, a set of snap-fit notches (4.3) are protected by the upper peripheral projection (4.2). The snap-in notches (4.3) are configured to snap into the groove (3.6) of the double coupling hook (3) by means of a striking force.

In addition, the cover frame (4) comprises a conical protuberance (4.1) configured to be inserted in the double coupling hook (3). Once inserted, the outer wall of the conical protrusion (4.1) should fully contact the inner wall (3.7) of the double coupling hook (3).

In addition, the cover frame (4) further comprises at least one spacer with a downward vertical rib (4.4) ^{configured to rest on the upper hemisphere of the cladding surface (} 12 ^{) in order to leave a} ventilation gap. Preferably, the at least one vertical-down rib spacer (4.4) is an array of vertical-down rib spacers (4.4) that further deploys from the lower end of the conical protrusion (4.1), thereby ensuring a gap ventilation between the cover frame (4) and the lining (12).

Method for mounting and dismounting a collar (1) on a cylinder (11)

Figure 3 schematically shows a flowchart with the sequence for assembling a collar (1) in a cylinder (11) of a gas bottle (10). The sequence comprising the steps of:

a) providing a gas container liner (12) comprising a flap bridge (14) for carrying such a liner while being held in the hand,

^{b) provide the collar (} 1 ^{) of figure} 2 ^,

c) hook the internal coupling (3.1) of the double coupling hook (3) with the flap bridge (14) of the ^{lining (} 12 ^),

d) engage the coupling lip (2.1) of the handle assembly (2) with the external threaded coupling (3.2) of the double coupling hook (3) by means of a rotating inward sliding movement until the spring locking system ( 2.2) of the set of handles (2) reaches the stopping point (3.3) of the external threaded coupling (3.2), thereby blocking the coupling flange (2.1) with the external threaded coupling (3.2), and

e) hook the cover frame (4) with the double coupling hook (3) in order to hide it.

In step c) of the above method, the flap bridge (14) of the gas container liner (12) is inserted into the internal coupling (3.1) of the double coupling hook (3). If the double coupling hook (3) is made up of two semicircular halves (3.4), the connecting pins (3.5) are connected sequentially to allow a pivotal joint and ease of embracing the entire perimeter of the flap bridge (14).

Once engaged with the flap bridge (14), the second connecting pin (3.5) is inserted thereby locking the double coupling hook (3) inside the flap bridge (14) in a strong and secure full perimeter joint. .

Furthermore, the latching in step d) occurs by means of a rotary sliding-in movement, preferably performed in an anti-clockwise direction, as opposed to the common screwing-unscrewing movement.

As a result, the stop point (3.3) restricts the ^{anti-clockwise rotary slide-in movement of the spring locking system ( 2.2 ) on the handle assembly (} 2 ^), thus locking it. way to the double coupling hook (3).

In step e) of the above method, the cover frame (4) is aligned with the double coupling hook (3) and snapped to it by means of a striking force. In particular, at least one snap-in notch (4.3) of the cover frame (4) is snapped into a groove (3.6) of the double coupling hook (3) by means of such snapping force. During insertion, an outer wall of the conical protuberance (4.1) comes into contact with contact with an internal wall (3.7) of the double coupling hook (3) all being protected by an upper peripheral projection (4.2).

Figure 4 schematically shows a flowchart with the sequence for disassembling a collar (1) from a cylinder (11) from a gas bottle (10). The sequence comprising the steps of:

^{a) provide a gas bottle (} 10 ^{) comprising a cylinder (} 11 ^{) with a gas container lining} (12), the lining which in turn comprises a flap bridge (14) and a collar (1) of the figure 2 mounted ^{on it, or a gas bottle (} 10 ^{) of figure} 1 ^,

b) provide a special tool (5) adapted to release the spring locking system (2.2), c) unhook a cover frame (4) from the double coupling hook (3) in order to allow access to the ^{locking system spring lock (} 2 ^. 2 ^).

d) release the spring locking system (2.2) in order to disable it from the stop point (3.3) on the external threaded coupling (3.2) of the double coupling hook (3) using the release tool, e) unhook the coupling rim (2.1) of the set of handles (2) of the external threaded coupling (3.2) of the double coupling hook (3) by means of a sliding movement outward rotating, and f) disengage the internal coupling (3.1) from the hook double coupling (3) of the flap bridge (14) of the ^{lining (} 12 ^).

In particular, in order to disassemble the collar (1) from the liner (12), in step d) of the above method, it is required to release the spring locking system by pushing it inward with a special tool (5) and release it from the stopping point (3.3) of the double coupling hook (3).

Thus, this allows for a clockwise-turn rotary slide movement ^{to unscrew the coupling flange ( 2.1 ) of the handle assembly (} 2 ^{) from the external threaded coupling} (3.2) of the hook double coupling (3).

It should be noted that the release tool is configured to push inward on the spring-loaded locking system, preferably the retractable tab. In a preferred example, this tool would only be accessible by authorized professional personnel in order not to damage any of the components during disassembly as a vandal proof barrier.

Also, in the case that the double coupling hook (3) is formed by two semicircular halves (3.4) during the subsequent disassembly method, it is further required to disassemble the connecting pins (3.5) either sequentially or at the same time. .
