OBJECT OF THE INVENTION
[0001] The invention, as it appears in the title of this specification, refers to a worktable,
which presents a series of novelty advantages and characteristics, that will be described
in detail below, that mean a significant innovation in the current state of the art.
[0002] This invention consists therefore in a worktable specially applicable to facilitate
cutting large-sized porcelain articles without discarding other types of materials,
being for that aim structurally designed with different boards in hinged connection
to a basic board, which are arranged supported on cushioning elements accompanying
all the time the segment of the piece to be cut, avoiding undesirable breakages.
FIELD OF APPLICATION OF THE INVENTION
[0003] The field of application of this invention is within the sector of the industry engaged
in manufacturing worktables, in particular focused in the area of the tables for cutting
flat pieces to work with large-sized porcelain materials or the like
BACKGROUND OF THE INVENTION
[0004] As it is known, the flat pieces of porcelain material as well as also others of other
materials such as glass, ceramic, or others, use to be cut with a cutting tool that
produces a mark or notch on the surface of the piece and thereafter slightly hitting
or pressing the segment to be cut, normally placing it on the edge of the worktable
to eventually breaking the piece just by the line that has been marked by the cutting
machine.
[0005] However, this operation, specially when it is dealt with large-sized pieces, for
example of 3000 x 1500 cm, is a very delicate and risky operation, because if the
break of the segment does not occur accurately on the marked line, the full piece
may be damaged and anyway, risks could be run that the segment to be cut is broken
when hitting it or when it falls down with the subsequent economic cost for waste
of material and the subsequent risk of injuries for the user.
[0006] The objective of this invention therefore is to develop a worktable that allows to
facilitate the described operation and make sure to achieve a perfect cut of the pieces
just by the notch the tool will mark, in every and each case, avoiding any suffering
of the segments cut, by means of a system of cushioned movable boards that accompany
the said segments all the time.
[0007] US2011232805 discloses a carpentry work station that comprises several boards that can be lowered
in order to redefine the working surface, mainly so it can be transported and stored
in a folded position.
[0008] As reference to the current state of the art, it shall be pointed out that, although
different models and types of worktables are known in the market, applicable to different
uses, some of them designed like the one herein to cut pieces, at least this applicant
is not aware of any showing technical and structural characteristics similar to those
shown by the table of the invention.
DESCRIPTION OF THE INVENTION
[0009] The table proposed by the invention, is therefore configured as a significant novelty,
within its field of application, because by implementing it, the above mentioned objectives
are satisfactorily achieved, the characterizing details making it possible and distinguishing
it from the already known are conveniently appearing in the final claims attached
to this specification.
[0010] What the invention proposes is a worktable the essential aim of which is to provide
an easy and safe system for cutting pieces of porcelain or of other similar materials,
in particular in order that, after the cutting machine produces the notch marking
the breaking line, to procure accompaniment to the segment to be cut supported all
the time and throughout it on a cushioned supporting surface while pressure is applied
on it to achieve the material breaking exactly by the said line.
[0011] For this, the worktable of the invention is essentially configured from a base board
supported on fixed legs, that can preferably be height-regulable to situate the table
at the required height and a series of supporting boards , at least one joined coplanar
to the base board in a hinged and cushioned way, so that, when pressure is applied
on them, they have the capability to be downwards folded to a certain extent, tending
to return to their horizontal position thanks to the said cushioning means.
[0012] Thus, the said supporting boards are used to place the pieces with the cutting line
on their point of hinged connection to the base board and with the part of the segment
to be split or broken arranged on them, while the rest of the piece rests on the base
board. And when the piece is placed in the said position, a pressure can be exercised
on the part of the segment to be cut being assured that the said pressure is correctly
distributed as the full piece is supported on a surface accompanying the segment.
[0013] It shall be pointed out that, although one or several supporting boards can be coupled
to the base board, in different options, in a preferred embodiment of the invention,
a first supporting board is coupled to the base board on one of its sides, a second
supporting board in another of its sides, concretely on the side adjacent to the one
being coupled to the first supporting board, and a third supporting board that, instead
of being coupled to the base board, is coupled between the first and the second supporting
boards, the said hinged connection being selectively with one or the other, by incorporating
a link rod linking them to each other, providing thus the possibility to extend the
surface of the table that constitutes a fixed board or a moving board and thus adapting
it to the different needs.
[0014] On their hand, the cushioning means providing that the accompaniment of the supporting
boards and their return to their initial position, in the preferred embodiment of
the invention, are formed by spring-loaded legs, which in addition are provided with
fastening means to avoid or not, as required, their use as a cushioning element. Thus,
the said legs are incorporated, at least, one under the different supporting boards
and, depending whether they have to be used or not, they are left unfastened in order
that the spring they incorporate acts or they are fastened in order they do not act
and serve as fixed legs.
[0015] According to another significant characteristic of the invention, the supporting
boards are coupled quickly and easy removable to the rims of the base board of the
table, by using tongue and groove connecting hinges, so that the full assembly can
be easily coupled and allows a way for dismounting the table for its transport and
transfer, the legs being also preferably dismountable, as well those fixed of the
base board as those cushioned of the supporting boards.
[0016] In a variant of embodiment, the boards can be replaced by a series of strips in a
parallel arrangement offering as a whole a surface on which the material to be cut
is supported.
[0017] Last, and in an already known way, the surface shows one or several lengthwise and/or
crosswise slots to insert buffer stops to position the pieces or the cutting machine.
[0018] Therefore, the main advantages the table of the invention provides are:
- The horizontal folding system of the supporting boards to facilitate cutting the large-sized
porcelain pieces that make a virtually perfect 90-degree cut, as the segment to be
cut never lacks the support of the table.
- The cushioned legs to facilitate folding the supporting boards that tends to return
to their position after they have been used.
- The multiple assistances to the work such as the slots for the locking toes for the
ceramic piece, the supporting boards being converted into extensions of the fixed
base board on its sides to allow different positions of the large-sized piece etc.
- The sizes of each of the boards to be used in different combinations. As well lengthwise
as crosswise.
- The handling of the table, fully dismountable in a few seconds to facilitate its transport
to any work place.
- The support for the cutting machine of different brands existing in the market, to
facilitate the work when cutting- separating the material.
[0019] The disclosed worktable consists, therefore, of an innovating structure having characteristics
unknown up to date for the purpose to which it is designed, reasons that, jointly
with its practical utility, provide it with sufficient ground to obtain the privilege
of exclusivity applied for.

PREFERRED EMBODIMENT OF THE INVENTION
[0021] At the sight of the said figures, and according to the numbering adopted, an example
of a preferred but not limiting embodiment can be seen in them, of the worktable of
the invention, which comprises the parts and elements that are indicated and described
in detail thereafter.
[0022] Thus, as it can be seen in the figure 1, the table (1) in question, is essentially
configured by a base board (2) having a rectangular plan supported on fixed legs (3),
preferably four legs, or that can be height-regulable, to which in an innovating way
is coupled, at least, a first supporting board (4) that is joined laterally to one
of the sides of the said base board (2) hinged and cushioned, that means, so that
it has the capability to be downwards folded to a certain extent, when applying pressure
on the said supporting board (4) tending to return to its horizontal position and
coplanar to the base board (2) when such pressure is no longer exercised, for which
an hinged connection through hinges (5, 6) and cushioning means (7) is contemplated.
[0023] Preferably, in addition, a second supporting board (4') is coupled to the base board
(2) in another of its sides, concretely in the side adjacent to that the first supporting
board (4) is coupled, in both cases with the same hinged connection system and cushioned
by means of hinges (5, 6) and cushioning means (7), and there also exists a third
supporting board (4") that is coupled to the first and to the second supporting boards
(4, 4') also by means of hinges (5, 6) and cushioning means, but including a linking
part (8) that, preferably consisting of a rod, allows its hinging or movement in conjunction
with one or the other, selectively.
[0024] Thus, such link rod (8), visible in the figure 15 and designed to be inserted in
holes (9) provided to that effect in coinciding points of the rims of the structure
of the supporting boards that remain facing each other, as it can be seen in the Figures
7 and 11, allows, depending if it is placed between the first supporting board (4)
and the third supporting board (4"), or between the second supporting board (4') and
the third supporting board (4"), to extend the surface of the supporting board that
is hinged with the base board (2) and with the other supporting board, on one side
or the other thereof as required.
[0025] In the figure 1 the full table of the said preferred option of embodiment can be
seen, with the base board (2) and the three supporting boards (4, 4', 4"), the points
of hinged connection where the folds of the said supporting boards are produced been
represented by means of a dashed line and their downwards tilting, by means of arrows,
the two possibilities it offers been shown as well by one side as by the other, that
means, as well lengthwise as crosswise, as required.
[0026] And in the Figures 2 to 12, the different base (2) and supporting (4, 4' 4") boards
can be seen, in different views to allow to appreciate all their characteristics.
[0027] As represented in Figures 6, 9, 12 and 13, the cushioning means (7) that determine
the supporting boards (4, 4', 4") tending to return to their horizontal position,
coplanar to the base board (2), preferably consist of cushioned legs that, formed
by two independent stretches (10) house a spring (11) within them, fastened to a support
(12) which, in addition, are provided with fastening means (13) to avoid the movement
of the said spring (11), for example a pin (13) that locks both stretches (10) of
the leg.
[0028] On their hand, the hinges (5, 6) that join in an hinged connection the supporting
boards (4, 4' 4") to each other and to the base board (2) are preferably easily dismountable,
and of tongue and groove coupling type, comprising, as shown in Figures 16 to 19,
female pieces (5) formed by a flatbar with drilled holes (14), in order it is screwed
on the board structure, and a window-shaped hollow (15) (figures 16 and 18), and male
pieces (6) formed by another flatbar with drilled holes (14), for screwing it, and
a hook-like curved protrusion (16), adapted to be imbedded in the window (15) of the
female pieces (5) (figures 17 and 19), so that the said coupling and its dismounting
result easy and quick.
[0029] Last, the surface of the base board (2) and of the supporting boards (4, 4', 4"),
that is covered with a soft material, of rubber type or the like, has one or several
slots (17) running crosswise and/or lengthwise from one end to another end thereof
been, if applicable; coincident in position between one and other boards, which are
designed to insert buffer stops (18) that, fixed by means of a suitable tightening
tool (19), serve to position the pieces to be cut on the table and avoid any undesirable
displacement thereof.
[0030] The nature of this invention being sufficiently described, as well as the way of
implementing it , it is not deemed necessary to extend any longer the explanation
in order that any person skilled in the art understands its scope and the advantages
arising from it.
