OBJECT OF THE INVENTION
[0001] As expressed in the title of the present specification, the invention relates to
a movable kitchen with adaptable accessibility, which provides to the function for
which it is intended several advantages and innovative features which will be described
in detail below.
[0002] More specifically, the object of the invention consists of a kitchen, specifically
the group of cupboards, furniture and elements which, located in a room, are especially
intended for the storage of utensils and foods as well as for incorporating the different
household appliances enabling the preparation of meals, which have the particularity
of having means which allow the movement thereof in a controlled manner and at will,
in the upward and downward directions, in order to make them more accessible for people
with reduced height or mobility, such as the elderly, the disabled, etc., for whom
the standard measurements and positioning that said elements typically have are a
barrier which seriously complicates the daily tasks for which they are intended.
BACKGROUND OF THE INVENTION
[0003] The problems which the disabled often have, especially those confined to a wheelchair,
due to the fact that most elements and apparatuses in any area of the industry are
studied without taking these people into account, are well known.
[0004] Therefore, in the case at hand regarding the furniture and elements forming conventional
kitchens, it is difficult, if not impossible, for the disabled to use such furniture
and elements due to the heights and positioning thereof.
[0005] This is because on one hand, worktops in which the burners and the sink are typically
located and in which the foods are prepared, have a height that cannot be easily accessed
if one does not reach the suitable height or remains standing; on the other hand,
the higher furniture is usually at a height that is likewise inaccessible, so said
people usually do not use them or have to have them placed at a much lower height,
therefore losing space between them and the worktop.
[0006] It is clear there is a need to create a system which allows adapting said elements
to the needs of each user, this being the main objective of the present invention,
with respect to which, on the other hand, currently and as a reference to the state
of the art, it must be mentioned that the applicant is not aware of the existence
of any other movable kitchen with adaptable accessibility having technical, structural
and configuration features that are similar to those of the kitchen herein proposed.
[0007] Some movable kitchens with adaptable accessibility are described in the following
patents: MU7102189,
DE10023203 and
DE19505391, which describe a movement of the kitchen furniture only in the vertical direction,
whereas patent
FR2906983 also describes a horizontal movement. Patents
US2007/0236114,
US4134629 and
US3857623 propose complex mechanisms to facilitate accessibility with a considerable increase
of the technical complexity and without the safety systems described in the present
invention, resulting in a complex assembly and making the maintenance and repair of
the proposed kitchen more difficult.
[0008] Japanese patent
JP2005/261885 describes a raised cupboard with a system of upward movement, downward movement and
forward shifting of its inner body and for the opening of the door covering only the
lower part of the outer part of the furniture. Said system used motors which are each
associated with a belt which, when wound and unwound, moves in the vertical direction
first vertical boards inserted between the outer part and the inner body of the furniture,
in turn moving downwards with the aid of guides and the belts themselves of said inner
body with respect to said vertical boards. This structure requires multiple assemblies
and layers of structural components: outer part, inner body and vertical boards for
connection between both of them, in turn using motors and belts. On the other hand,
the use of belts makes the system more complex because the placement of a single belt
and motor in one of the sides provides a rather unstable mechanism that is susceptible
of experiencing continuous breakdowns and in contrast, the use of two motors and a
belt on each side again increases the complexity of said system, as well as causing
higher maintenance, assembly and manufacturing costs, and a risk of the belt slipping
out of the pulley/pulleys.
DESCRIPTION OF THE INVENTION
[0009] Therefore, the kitchen proposed by the invention is configured as an evident novelty
because due to its application, the problem of accessibility in the kitchen which
a wide range of people suffer is specifically lessened, allowing such people to move
and place the different elements, furniture and apparatuses of the kitchen at will
in order to be able to work comfortably, subsequently being able to put them again
in their place once the work is done.
[0010] To that end and specifically, the movable kitchen proposed by the invention consists
of a set of raised furniture, each of which furniture independently by means of the
operation of a remote control designed for that effect and as a result of the incorporation
of a system of motors and guides, moves upwards and gradually moves forwards until
the level of the worktop, while at the same time the door thereof opens automatically,
and when it moves up such door closes in the same manner.
[0011] The door of the furniture can also open or close manually, as in traditional furniture.
[0012] Since the furniture remains at the level of the worktop, and furthermore moved forward
to almost the edge thereof (worktops are usually wider than the cupboards), the inside
thereof is within reach of any disabled person and/or person with limited mobility
or height.
[0013] The cupboard returns to its original position, the door closing again, upon receiving
the corresponding order, operating the mentioned remote control.
[0014] In parallel, the invention also provides a movable worktop or tabletop, which can
cover all of it, a significant part or be divided into two or more parts with independent
mobility, being able to move upwards and move downwards at different heights, at will
of the person giving the order, also by means of the operation of a remote control,
and manual push buttons, and as a result of a system of motors and guides; or alternatively,
as a result of a system of motors, legs, central electronic control and safety mechanisms,
which prevent the worktop from being able to accidentally trap and press against the
body of a person or thing.
[0015] It should be pointed out that both the raised cupboards and the tabletop have a safety
system. In the case of the raised furniture, it is a contact system which detects
any interference in the pre-established path, not only immediately paralyzing the
downward movement of the cupboard, but also automatically initiating its upward movement
after a few seconds to return to the original position. In the event that the safety
detection system for lowering the cupboard should fail, the motor moving each inner
body of the cupboard pulls on same when it moves upwards, but in contrast it does
not push the inner body of the cupboard when it is lowered; this is achieved by means
of a connection of the motor with the inner body by means of high-strength flexible
cloth. Therefore, if the furniture runs into an obstacle when it is being lowered,
such as the body of a child, for example, even if the contact safety mechanism fails,
the pressure that would be exerted on the body of the child would be that of the weight
of the furniture and the content thereof, but it does not add the pulling force of
the motor.
[0016] The use of said flexible cloth is a simple technical solution that is easy to maintain
and assemble during its assembly in the factory or repair, especially if it is compared
with an assembly by means of belts. On the other hand the use of belts continuously
transmitting force to the inner module is dangerous because in the event of the failure
of the safety mechanisms, a person trapped by the inner body during its downward movement
would have to support the weight of said inner body plus the pulling force of said
motor. Likewise, the use of a flexible cloth prevents problems of belts coming out
of the guide pulleys. Finally, in addition to providing a simple safety system, the
use of a flexible cloth typically allows, using the same materials, higher breaking
and tear strength indexes.
[0017] Furthermore, roller-flexible band connections are known in the state of the art,
which even in the event that an object is trapped, if the motor continues to rotate
the flexible cloth would start to wind in the reverse direction, transmitting a downward
movement of the furniture, thus releasing the obstacle.
[0018] In the case of the tabletop, it incorporates a system of side sensors which stop
the movement thereof due to any obstacle, and additionally, if desired, an innovative
system of sheets by means of which if the tabletop runs into an obstacle in the downward
movement, they also stop the mechanism.

PREFERRED EMBODIMENT OF THE INVENTION
[0020] In view of the mentioned figures, and according to the reference numbers used, a
preferred embodiment of the kitchen object of the invention, comprising the parts
and elements indicated and described in detail below, can be seen.
[0021] Therefore, as can be seen in said figures, the movable kitchen in question comprises
a set of cupboards (1) of the raised type, i.e., they are located in the upper part
of the kitchen, each of which has its corresponding door (2), being formed, as is
observed in Figure 2, by three outer boards (3) forming a fixed outer box, inside
which an inner movable body (4) fits, laterally having a system of slide guides (5)
complemented with the guides (5') provided laterally inside the outer box (3), which
will direct the downward and forward movement of the inner body (4), in the shifting
of which the wheels (6) provided in the upper part thereof will cause the opening
of the door (2), hingedly fixed at the upper part thereof to the fixed outer box (3).
[0022] Figure 3 shows a variant in which four outer boards form a fixed outer box (103),
inside which an inner movable body (104) fits, laterally having a system of slide
guides (105) complemented with the guides (105') provided laterally inside the fixed
outer box (103), which will direct the downward and forward movement of the inner
body (104), in the shifting of which the wheels (106) provided in the upper side part
thereof will cause the opening of the door (102), hingedly fixed at the upper part
thereof, by means of a raisable spring element (111), to the fixed outer box (103).
[0023] For performing said shifting of the inner body (4), the cupboard (1) has a roller
(7) fixed internally to the aforementioned outer box (3) which is associated with
a motor (8) having a of a high-strength pull band or cloth (9), the mechanism being
operated through a remote control (not depicted) specially programmed for such purpose.
[0024] In certain cases in which the inner drawer (4) houses elements having a greater weight
or volume, such as a microwave (10) or the like, the cupboard (1) incorporates a second
thrust motor (25) which initially separates the door (2) from the outer box (3), facilitating
the downward movement of the inner body (4). Alternatively, as depicted in Figure
3, the door (102) incorporates cams (113) which initially separate said door (102)
from the fixed outer box (103), facilitating the downward movement of the inner movable
body (104).
[0025] As can be seen in Figure 2, said inner body (4) can optionally incorporate an accessory
(11) suitable for coupling different small household appliances thereto.
[0026] In Figure 2 it is seen that each cupboard (1) furthermore has a safety system formed
by two metallic sheets (12) and (13) located in the lower part thereof, the upper
sheet (12) of which is directly screwed to the inner body (4) and the lower sheet
(13) has a series of side holes (14) which are used for the securing to the body (4),
by means of screws serving to operate the safety mechanism, since said holes (14)
are slightly larger than the screw, which provides an allowance between the sheets
(12) and (13). If the mechanism collides with an obstacle when the body (4) moves
downwards, the lower sheet (13) will make contact with the upper sheet (12), closing
an electric circuit connected to motor (8), and therefore operating the safety mechanism,
which will reverse the direction of rotation of the pull band or cloth (9), making
the body (4) move upwards again.
[0027] Figure 3 shows a variant of the safety system for the cupboards, in which each cupboard
has a safety system formed by a sensitive membrane (112). If the mechanism collides
with an obstacle when the inner movable body (104) moves downwards, the sensitive
membrane (112) will make internal contact, closing an electric circuit connected to
the motor (108) and therefore operating the safety mechanism, which will first stop
the lowering movement to reverse it in a few seconds and take the inner movable body
(104) to its original position.
[0028] Additionally, both in the embodiment in Figure 2 and in the alternative of Figure
3, and in the event that the contact safety system of the sheets (12,13) or, where
appropriate, the sensitive membrane (112), fails, the motor (8,108) which moves each
inner body (4,104) pulls on said inner body (4,104) when it moves upwards, but in
contrast, it does not push the inner body when it is lowered; this is achieved by
means of a connection of the motor with the inner body by means of the aforementioned
high-strength pull band or cloth (9,109) which will be highly flexible, even in the
case of opposing forces (the thrust force of the motor and the resistance force of
the intercepted body or object) located in the plane thereof.
[0029] In turn, as can be seen in Figure 1 and with greater detail in Figure 4, the invention
also comprises a movable worktop or work table (15), formed by a board or tabletop
(16) which moves upwards and downwards by means of a motor (not depicted) operated
in the same manner by a remote control programmed for such purpose.
[0030] Said tabletop (16) is arranged on a metallic structure (17) which is provided with
a safety system formed by a metallic sheet (18) located in the front part thereof
and fixed thereto by means of screwing; and on which there is another sheet (19) fixed
to the former by means of screws inserted in the holes (20) provided in the sheet
(18), which holes (20) are larger than the screws such that there is a certain allowance
between both. Therefore, if the front sheet (19) collides with an obstacle in the
downward movement of the tabletop (16), it will move upwards and operate the safety
mechanism by means of an end switch or switch which will stop the movement of the
motor.
[0031] The tabletop (16) furthermore has at least one photoelectric cell (21) and a reflector
(22) arranged on the sides thereof as additional safety elements.
[0032] It should be pointed out that the structure (17) on which the tabletop (16) is supported
and fixed by means of screws (23), in which the plate and the sink could furthermore
be installed, in which case they will have the corresponding flexible connections
allowing movement, has other leveling screws (24) for the correct installation thereof.
[0033] The flexible connections are the sink drain connections and the domestic (hot and
cold) water intake connections so that they allow movement of the worktop.
[0034] Alternatively, as can be seen in Figure 5, the movable worktop or work table is formed
by a decorative board or tabletop (216), which moves upwards and downwards by means
of motor-driven legs (226), operating same by push buttons (227) and, optionally,
a remote control programmed for such purpose.
[0035] Said decorative tabletop (216) is arranged on a metallic structure (228). This tabletop
has a system of sensors (230) which stop the movement thereof when it runs into an
obstacle in its lowering path. This is achieved because the sensors have an emitter
which sends a light beam to a receiver and when this beam is interrupted, the latter
acts and the movement is stopped.
[0036] The motor-driven legs (226) which operate the worktop are covered with telescopic
covers (229,229') made of the same decorative material, arranged in two parts per
motor-driven leg (226) so that they can run the same distance as the leg.
[0037] Each motor-driven leg (226) is secured with the following fixings: leveling fixing
plate (233) anchored to the metallic structure (228) by means of leveling screws (231)
and fixing screws (232); floor fixing plate (234); and side fixing square (235).
[0038] In the event that any anomaly is detected, the safety system of the tabletop in any
of the alternatives of Figures 4 or 5 renders the worktop inoperative, always giving
priority to safety over operation.
