Definitions
- the present invention relates to a piece of furniture with a seat, the seat of which can be moved along two non-vertical articulation axes.
- Many chairs include a backrest that can recline to improve user comfort. Certain armchairs also combine it with means of vibration to massage the user and give him a feeling of relaxation.
- Such armchairs can thus be found in public places such as airports or train stations but also in private homes.
- An object of the invention is to provide an improved alternative to the seating furniture of the prior art.
- a piece of furniture comprising a seat carried by a base by means of articulation means of the seat on the base.
- the articulation means are arranged to allow movement of the seat around two non-vertical axes.
- the relative position of the seat with respect to the base can be modified around two non-vertical axes. A user can thus be easily moved into different positions. In addition, under the effect of gravity, the movements of the seat naturally provide a massage for the user.
- seat cabinet a cabinet the main function of which is to allow a user to sit down or lie down, the seat cabinet comprising in particular a backrest (inclined or horizontal) against which the seat is placed. user comes to support his back.
- a piece of furniture with a seat within the meaning of the invention is for example a cradle, a bed or even an armchair ...
- the two axes are substantially horizontal rate.
- the two axes are substantially or thogonal.
- the piece of furniture comprises means for actuating the seat around these two axes, the actuating means being connected to a control unit to obtain at least one movement of the combined seat around these two axes.
- the articulation means ensure movement of the seat in a given volume defined by a dome.
- the piece of furniture comprises a cap forming said dome and inside which the articulation means can be arranged at least in part. If the articulation means comprise two arches, at least one of the arches will be arranged in the cap.
- the dome has a center arranged above the seat.
- the cabinet has at least one sensor arranged to detect a state and / or a physiological response of a user of the furniture.
- the senor is a weight sensor.
- the senor is a muscle sensor.
- the cabinet comprises at least one system chosen by one of the following systems: a massage system by vibration, a massage system by massage heads, a heating system, an audio system.
- Figure 1 is a schematic view of part of a piece of furniture according to a first embodiment of the invention
- FIG. 2a is a diagram illustrating a first sequence that can be implemented by the cabinet illustrated in Figure 1,
- FIG. 2b is a diagram illustrating a second sequence that can be implemented by the cabinet illustrated in Figure 1,
- FIG. 3 is a schematic view of a piece of furniture according to a second particular embodiment of the invention.
- the piece of furniture is here an armchair 1 which comprises a seat 2 carried by a base 3 by means of articulation means 4 of the seat 2 on the base 3.
- the base 3 comprises at least one foot resting on the ground.
- the base 3 comprises two rest feet 5, 6 each formed of a bar resting on the ground, the two bars being parallel to each other.
- a third bar 7 of the base extends transversely between the two rest legs 5, 6 to make them integral with each other.
- the base 3 furthermore comprises an arm 8 extending straight from the third bar in the direction of the seat 2.
- the base 3 is here shaped so that the arm 8 extends along a third substantially vertical axis Z.
- the base 3 is for example made of metal.
- the seat 2 has both a back 9 and a seat
- a user can therefore sit or lie down in the chair 1, his back being supported by the backrest 9 and his legs supported, at least in part, by the seat 10.
- the seat 2 is also sufficiently wide so that the user can rest his arms on the seat 2 while extending them along his body.
- the back 9 and the seat 10 are preferably in one piece.
- the seat 2 is here formed of a single shell coated at least on the face intended to receive the user with a flexible material such as, for example, foam.
- the angle formed inside the seat 2 between the back 9 and the seat 10 (also called the seat angle) is between 125 and 130 degrees and is preferably 127 degrees.
- the articulation means 4 are arranged to allow movement of the seat 2 around two non-vertical X, Y axes.
- the two axes X, Y are orthogonal to each other.
- the two axes X, Y are substantially horizontal.
- the two axes X, Y are here substantially orthogonal to the third axis Z.
- the articulation means 4 are furthermore shaped so that the first axis X corresponds substantially to the pitch axis of the seat 2 and the second Y axis to the roll axis of the seat 2.
- the chair 1 is configured to ensure movements of the seat 2 with an amplitude of between 0 and 90 degrees along the first axis X and of 0 and 90 degrees along the second Y axis.
- the chair 1 is here shaped so that the second Y axis is substantially parallel to the axis along which the straight rest feet 5, 6 extend from the base 3.
- the articulation means 4 are furthermore shaped to allow movement of the seat 2 in a combined manner around the first axis X and the second axis Y.
- the chair 1 can thus move the user in an orbital movement.
- the articulation means 4 do not allow movement of the seat 2 around the third axis Z.
- the seat 2 is therefore only movable in the bital gold plane.
- the articulation means 4 are arranged so as to move the seat 2 only in a geometric volume which is substantially dome-shaped and for example along the outer surface of said geometric volume.
- the dome is centered on the arm 8 and therefore here coaxial with the third axis Z.
- the domed part of the dome is here turned towards the pedestal 3.
- the center C of the dome in this case belongs to the third Z axis and is located above the seat 2.
- the movements of the seat 2 can thus be part of a concave surface.
- the dome is here substantially hemispherical.
- the articulation means 4 are themselves arranged in this geometric volume in the form of a dome.
- the articulation means 4 comprise a first gutter which is mounted on the arm 8 at the level of the free end of said arm 8 and in a centered manner with respect to said arm 8.
- the first gutter is here fixed on said arm 8 so that the first channel and the arm 8 are integral with each other.
- the articulation means correspondingly comprise a first carriage (not shown here) connected to the seat 2 and slidably mounted in the first gutter so that a translation of the first carriage in the first gutter causes a rotation of the seat 2 around the first X axis.
- the first carriage comprises in the lower part a first arch 11 sliding in the first gutter.
- Said portion is more particularly shaped so as to have the same center of curvature C as the contour of the aforementioned geometric volume.
- the first arch 11 extends so that a projection of said first arch 11 on the ground extends between the two rest feet 5, 6 of the base 3 and substantially parallel to said rest feet 5, 6 .
- the first carriage itself forms a second gutter in its upper part.
- the articulation means correspondingly comprise a second carriage (the representation of which has been simplified) which is this time fixed to the seat 2.
- the second carriage and the seat 2 therefore form a unitary assembly in the present case.
- the second trolley is slidably mounted in the second gutter so that a transfer of the second trolley into the second gutter results in a rotation of the seat 2 around the second Y axis.
- the second carriage comprises in its upper part a second hoop 12, portion of the second carriage fixed to the seat 2.
- the center C of curvature of the second hoop 12 is the same as that 11 of the first carriage.
- the chair therefore has two arches 11, 12 arranged at 90 degrees to each other.
- the arm 8 stops here at the first hoop 11.
- the two arches 11, 12 are for example made of metal.
- the two arcs 11, 12 form arcs of a circle of approximately 180 degrees.
- the first gutter assembly - first carriage ensures the rotation of the seat 2 along the first axis X, that is to say the pitch of the seat and the second gutter assembly - second carriage rotates the seat 2 along the second Y axis, that is to say the roll of the seat 2.
- the two sets are arranged substantially at 90 degrees to each other, the first set under the second apparently.
- the user can feel rolling and pitching movements in a concave position.
- the chair 1 can move the user in an orbital movement which is relaxing, stimulating, rejuvenating ... according to the sequence of movements chosen ..
- the chair 1 comprises means for automatic actuation of the two assemblies.
- the actuating means comprise a first actuating device of the first assembly and a second actuating device of the second in appearance.
- the first device comprises a first motor and a first pulley-belt group.
- a belt is connected at a first end to the pulley integral in rotation with the output shaft of the first motor, and at a second end to a pulley integral with the first carriage and typically with the first arch 11 of the first carriage so that 'a rotation of the first motor causes sliding of the first hoop 11 in the corresponding channel and therefore a pivoting of the seat 2 around the first axis X.
- the first device is also shaped to ensure a pivoting of the seat 2 around the first X axis in both directions of rotation.
- the first motor is here offset and arranged at the level of the rest feet 5, 6 of the base 3.
- the second device comprises a second motor and a second pulley-belt group.
- a belt is connected at a first end to the pulley integral in rotation with the output shaft of the second motor, and at a second end to a pulley integral with the second carriage and typically with the second arch 12 of the second carriage so that 'a rotation of the second motor causes a sliding of the second arch 12 in the corresponding channel and therefore a pivoting of the seat 2 around the second axis Y.
- the second device is also shaped to ensure a pivoting of the seat 2 around the second Y axis in both directions of rotation.
- the second motor is here arranged at the level of the first arch 11.
- the wheelchair 1 comprises means for supplying the wheelchair 1 in order to make it autonomous (for example the supply means comprise one or more batteries arranged in the wheelchair 1).
- the chair 1 has at least one port for connection to an external power source of the mains power supply type.
- the chair 1 comprises at least one chair control unit and in particular actuation means.
- the unit is for example a calculator, a computer, a microcontroller ...
- the unit is arranged in the chair 1 or is deported from the body of the chair 1 while being in communication with said chair body 1. Communication with the chair 1 he unit can be wired or wireless (via wifi, bluetooth, etc.).
- the unit is configured to control the movements of the seat 2 along the first X axis and / or the second Y axis.
- the unit can thus position the seat 2 according to different lateral positions and / or more or less inclined positions.
- the seat 2 cannot be inclined lower than a position corresponding substantially to the sitting position of the user.
- the seat 2 can for example, and without limitation, be brought into six main distinct positions:
- a first position 21 called neutral position (the user is substantially in a seated position with his feet on the ground and his right pelvis)
- a second position 22 called the central semi-extended position (the user is substantially in a semi-extended position and the pelvis is straight),
- a third position 23 called the central three-quarter position (the user is substantially in a three-quarter lengthened position and the right pelvis), - A fourth position 24 called the central lying position (the user is substantially in the extended position and the pelvis right),
- a fifth position 25 called the lying position tilted to the right (the user is substantially in the lying position and the body tilted to his right), and
- a sixth position 26 called the extended position tilted to the left (the user is substantially in the extended position and the body tilted to his left).
- the unit can also control a sequence of movements of the seat 2: oscillations and / or rockings and / or general trajectories.
- oscillations and cradles both oscillations and cradles correspond to rotations around the first X axis or the second Y axis, however the oscillations have a lower amplitude of movement than that of the cradles.
- the oscillations have an amplitude of a few millimeters and the rockings have an amplitude of at least a few centimeters.
- the unit can control the chair 1 so that the seat 2 follows an overall trajectory while performing oscillating and / or rocking movements during the trajectory with possible pauses at the level of the trajectory and / or oscillations and / or rockings.
- the unit can therefore control in particular both the realization of a general movement combined with movements of lesser scope (rocking and / or oscillation).
- the unit can also control various oscillations and / or rocking amplitudes and / or various trajectories as well.
- the armchair 1 thus ensures an overall movement of the seat 2 inscribed here in a sphere with sequences cradles and / or oscillations and / or trajectories.
- the unit is configured to be able to control, if necessary, movements of the seat 2 at different frequencies and / or different speeds.
- the unit can for example control a displacement of the seat 2 at a speed between 0.005 and 25 millimeters / second and / or control an oscillation and / or rocking of the seat 2 at a frequency between 0.2 and 0.3 Hertz.
- the unit can also control a wider range of motion sequences with the possibility of acceleration and / or deceleration on the overall trajectory and / or in rockings and / or in oscillations.
- Each movement can therefore be continuous or discontinuous with or without pauses and variable speeds or frequencies or not.
- the unit can also combine sequences of continuous movements, various trajectories (linear, circular, spiral ...), oscillations, rocking, pauses, decelerations, accelerations ... with amplitudes, variable times, speeds, frequencies.
- the unit controls the seat 2 so that it follows a general trajectory in an arc of a circle going from the fifth position 25 to the sixth position 26 via the fourth position 24 and vice versa.
- the passage between the fifth position 25 and the sixth position 26 is symbolized by dots: each point optionally corresponds to one or more pause (s) and / or oscillation (s) and / or rocking (s).
- the unit controls the seat 2 so that it follows a general spiral path passing successively through the second position 22, the third position 23, the first position 21, the fifth position 25, fourth position 24, sixth position 26, first position 21, third position 23 and second position 22 and so on or vice versa.
- the passage between these different positions is symbolized by dots: each point optionally corresponds to one or more pause (s) and / or oscillation (s) and / or rocking (s).
- the chair 1 comprises at least one sensor connected to the unit for controlling the chair 1.
- the sensor is for example a sensor capable of detecting a state and / or a physiological response of the user.
- the senor is a weight sensor.
- the unit typically adapts the movement sequences to the weight of the user, for example by adapting the speed of the movements.
- the unit locks the seat 2 to the base 3 if no presence is detected in the seat 2 by the weight sensor.
- the senor is a muscle sensor for measuring the muscle tension in an area of the user.
- the unit adapts the movement sequences to this tension, for example by emphasizing oscillations and / or rockings.
- the chair 1 comprises at least one system complementary to the articulation means 4 offering an orbital movement to the user to increase interaction with the user.
- the chair 1 comprises at least one vibration massage system.
- Said system comprises for this purpose at least one and preferably several vibrating elements arranged in the seat 2.
- Each vibrating element comprises for example a motor for generating the vibrations.
- the elements are located in only one area of the seat 2 (for example the backrest) or are distributed over the entire surface of the seat 2. The distribution can then be homogeneous or irregular (for example only along the center line length of the seat 2 to preferentially massage the user's spine).
