PURPOSE OF THE INVENTION
[0001] This invention refers to the improvements incorporated in wine barrel racks, which
are used in large wine cellars to be precise. These improvements permit the accumulation
of barrels, stably supported in horizontal position without them to withstand the
weight of those arranged above them; as the load of each and every one of the barrels
is transferred directly towards the floor via the structure defined by the racks.
In other words, the barrels are only required to support their individual load.
[0002] The invention improvements are designed to facilitate the mobility of each of the
barrels within the within the corresponding rack.
INVENTION BACKGROUND DATA
[0003] In the large wine cellars, wine aging in barrels is done via the accumulation or
piling up of the barrels, in an horizontal position, i.e., with their bases resting
against vertical planes, so that the barrel bottoms rest between pairs of beams arranged
in parallel on the floor, and conveniently wedged to prevent displacement, but at
the same time guaranteeing a stable positioning of the barrels in question.
[0004] The subsequent barrel levels are obtained by resting the barrels in between each
other so they finish arranged in quincunxes, always equipped with wedges, and piled
up as high as necessary, limited logically by the height of the cellar.
[0005] This system of piling up, commonly used in the large wine cellars for aging wine,
presents a series of problems and inconveniences, which to date have yet to be resolved,
and are as follows:
- The stability of the barrels lacks security, since this is exclusively obtained by
means of wedges, which in the event of these "failing", the barrels would obviously
move, in other words collapse, involving the subsequent accident risk of the workers
engaged in their tasks within the cellar, not to mention the economic cost involved.
- Barrels, which are piled up forming different levels, all resting against each other
implies handling difficulties.
- The barrels on the lowest levels are obliged to withstand the weight of the higher
ones. Naturally, a barrel is manufactured in relation to its function and the load
of its contents when full. Therefore, barrels are normally not designed to withstand
heavy weights, which means that when are piled up as set out above, they may become
deformed or damaged.
[0006] In an attempt to solve this problem, the petitioner himself is the owner of the Spanish
utility model U 9801070, describing a wine barrel rack. This consists of a rectangular
shaped metal structure, constituting the rack base, equipped with the corresponding
apices of vertically orientated tubular sections destined for immobile coupling of
vertical posts or columns acting as separators in the piling up between the racks,
whose length must obviously be greater than the maximum diameter of the barrels, including
the mentioned base with leg supports on the rack posts immediately below, plus a metal
structure constituting the base of each rack in relation to the crossbeams, with cross-sections
or rods appropriately shaped to form cavities for perfect stabilisation of the barrels.
[0007] In this way each rack accommodates two laterally adjacent, perfectly stabilised barrels
on the mentioned cross-sections or rods attached to the base structure. On top of
this pair of barrels others can be arranged, resting only the legs of each one on
top of the posts immediately below, with the metal structures sufficiently separated
so the barrels are physically independent of each other.
[0008] The petitioner himself, is also the owner of the European patent number 99500085.8
"Improved support for barrels" and of the European patent 99500111.2 "Support structure
for wine barrels", where with modifications in relation to the previously mentioned
utility model, racks are obtained which can be assembled together with considerable
lateral displacement, in a quincunxes arrangement to be precise, applicable to the
relative arrangement between the barrels themselves.
[0009] These racks, whilst completely resolving the previously mentioned problem, also present
a problem, which is the mobility of the barrels themselves, mobility which may be
necessary for different causes, such as when controls are carried out regarding the
reduction or leakage, on decanting, cleaning the barrel, etc.
DESCRIPTION OF THE INVENTION
[0010] The improvements proposed by the invention fully resolve the problem previously set
forth, allowing easy movement of the barrels within their racks, to the extent these
may freely rotate on their own axis with minimum effort.
[0011] To this end and more specifically starting from the structuring similar to that of
the previously mentioned utility model 9801070, the invention improvements consist
of replacing the cross-sections or rods for the seating and stabilisation of the barrels
for pairs of wheels assembled with free rotation on short arms, in such a way the
said wheels become barrel supports, allow free rotation of the same on their own axis
with minimum effort as previously mentioned.
[0012] In accordance with the other invention features the said arms will adopt oblique
arrangements, preferably radials in relation to the barrel, for the purpose of an
optimum transmission of efforts towards the rack structure.
[0013] It has also been foreseen that the said wheels be sufficiently resistant to withstand
the barrel load, but at the same time of a material sufficiently soft, so as not to
mark or damage the barrel surface, both in the stable position of the same, as when
it is subjected to a rotary movement.
[0014] In this way, easy movement is obtained on those occasions when the barrel, has to
be refilled either due to depletion or leaks. It also facilitates the extraction of
the wine during decanting, and the barrel can be cleaned "in situ" without the need
for displacements, since the analogous form of its nozzle can be orientated laterally
or downwards, again with minimum effort.
[0015] Finally and in accordance with the other invention characteristics, it has been foreseen
the posts acting as separators between the racks can be folded onto the base structure,
instead of being dismountable, for the purpose of facilitating and simplifying the
rack folding operations during its storage and transport when empty, as well as facilitating
its unfolding, i.e., converting it to the operative position.
DESCRIPTION OF THE DRAWINGS
[0016] To complement this description and for the purpose of offering a greater comprehension
of the invention characteristics, in accordance with a preferential practical execution
of the same, a set of drawings are attached as an integral part of the said description,
where the following has been represented in an illustrative but not limiting fashion:
Figure 1. ― By means of a schematic representation with frontal elevation shows a
barrel rack executed in accordance with the improvements, which are the purpose of
this invention.
Figure 2. ― Shows a floor view of the rack in the previous figure.
PREFERENTIAL EXECUTION OF THE INVENTION
[0017] With these figures it can be seen how the rack according to the invention improvements
is structured on a base platform (1) preferably metal, set on crossbeams and head
beams conferring it structural rigidity, to withstand the loads to which it is to
be subjected, defining a rectangular shape with appropriate dimensions for a pair
of barrels (2). Its apices are attached to corresponding vertical posts (3). Likewise,
its upper end surpasses the highest barrel level (2), in such a way that the posts
act as separators in the piling up between racks, transmitting the efforts directly
between them, through the said posts (3), without the barrels (2) being affected by
the load placed on top of them. The said posts (3) could be hollow free ends with
its bottom end having a wedge (4) that can be plugged into the said hollow ends, to
stabilise the assembly in the light of possible forces tending to create transverse
displacements between the racks.
[0018] From this basic structure and in accordance with the invention improvements, on the
cross beams (5) of the base structure (1), these are firmly joined to the same pairs
of arms (6), in such a way that the arms of each pair are symmetrically arranged in
relation to the imaginary vertical diameter of the barrel (2), in the position planned
for the same. Each one of these arms (6) has a wheel (7) on the end, assembled with
free rotation, constituting a support point for the barrel (2), in such a way that
each barrel rests on four wheels, as can be seen on the floor view of figure 2; perfectly
stabilised, but with the possibility of turning on its own axis, with the application
of minimum effort.
[0019] The arms (6) will preferably have a tilted arrangement, clearly radial in relation
to the barrel (2) they have to support, for the purpose of improving the transmission
of efforts towards the base structure (1) due to the barrel's own weight including
its contents.
[0020] Furthermore the axes (8) of the wheels (7) must also adopt an oblique position, in
such a way they finish parallel to the barrel's imaginary tangent at its point of
contact on the wheel with the same.
[0021] As previously mentioned the wheels (7) have to be of sufficiently resistant material
to withstand the efforts to which they are to be subjected, yet at the same time sufficiently
soft so as not to mark the external surface of the barrel, both when resting stably
on the wheels and when subjected to a rotary movement on their own axis.
[0022] Finally, the posts (3) are attached to the base structure (1) via articulated joints
(9) enabling their tilting between two limit positions. A tilting on its own base
structure (1) corresponding to the storage, transport situation i.e. when the rack
is inoperative; and the other, that represented in figure 1, where it adopts a vertical
arrangement, which under no circumstance may be surpassed in an outward direction.
In this sense, and as shown in the said figure 1, the tilting axis (9) for the posts
(3) may be clearly situated above the lower end of the same, in such a way that the
said lower end rests against the corresponding end of the base structure (1), acting
as a tilt buffer limit going outwards, for the said posts. Nevertheless, any other
limit system may be used provided it establishes the said limits.
1. Improvements in the barrel racks, particularly in racks set on a rectangular shaped
base structure, preferably metal, defining seatings for a pair of barrels, laterally
adjacent from whose apices emerge posts acting as separators in the piling up between
racks. The said seatings for each barrel (2) consist of on four wheels (7) assembled
with free rotation at the end of the respective arms (6) conveniently fitted to the
base structure (1), in such a way, the said wheels (7), apart from stabilising the
barrels (2), also allow rotation of the same on their own axis with minimum effort.
2. Improvements in the barrel racks according to the 1st claim, so defined, because the mentioned arms (6) adopt an oblique position, preferably
radial in relation to the corresponding barrel (2) for an optimum transfer of efforts
towards the base structure (1).
3. Improvements in the barrel racks according to the 1st claim, so defined, because the axes (8) of the wheels (7) are arranged in parallel
to the imaginary tangent to the barrel on the wheel resting point (7) on the same.
4. Improvements in the barrel racks according to the 1st claim, so defined, because the wheels (7) are made from a material, which apart from
being sufficiently resistant in relation to the barrel load with its contents, does
not produce marks on the barrel (2) either in a stable situation for the same or when
the said barrel is subjected to rotation on its own axis.
5. Improvements in the barrel racks, according to the 1st claim, so defined, because the posts (3) are connected to the base structure (1)
by tilting axes (9) allowing the said posts to be folded onto the base structure,
in the inoperative rack position, whose tilting is limited, in the contrary direction
by means of appropriate buffers, perpendicular to the posts (3) in relation to the
base structure (1).
