Definitions

  • the present invention relates to a support, in particular for legs in seating and/or reclining furniture, a control unit for this, a delivery mechanism for this and its further use.
  • Scissor frames are used to enable comfortable sitting and/or lying on seating and/or reclining furniture. These scissor frames form an elaborately complex folding mechanism, by means of which footrests and/or legrests are held in the basic position below the seating and/or reclining furniture. If a user who is sitting on the seating and/or reclining furniture would like to put their legs up, a coupling mechanism is activated by applying pressure to the backrest, which folds out the scissor frame with the footrest arranged on it. The scissor frame is moved into the use position. If the user then wants to get up, they press the footrest with their feet and legs so that it folds back down and the backrest stands up again.
  • Such scissor frames often prove to be disadvantageous in practice, as a complex mechanism must function smoothly to ensure functionality.
  • the scissor frames are often open in the use position, i.e. in the unfolded state, which can result in finger bruising or other injuries to the user.
  • such scissor frames are sensitive to dust, so that the function itself is limited.
  • footrests based on a scissor frame Another disadvantage of the footrests based on a scissor frame is that the footrest closes off the body of the seating furniture at the bottom. This makes it significantly more difficult for the user to get up. In addition, such seating furniture is visually very massive and not particularly appealing.
  • the present invention has the object of providing a leg rest which can be moved particularly comfortably and easily from the basic position to the use position and vice versa.
  • the support described here for the first time in particular for legs, for seating and/or reclining furniture, has a compact arrangement with a minimization of the support surface in a basic position and/or an enlargement of the support surface in a position of use.
  • the support described here can provide an increase in the support surface, so that legs and/or feet can be placed on particularly comfortably.
  • the term enlargement of the support area is advantageously understood to mean that in the use position a larger area is provided for placing legs and/or feet than is the case in the basic position.
  • the support enlargement for seating furniture and/or reclining furniture is designed by means of a folding mechanism and/or swivel mechanism and/or guide link mechanism and/or telescopic rail mechanism and/or ball bearing mechanism and/or slide rail mechanism and/or length change mechanism .
  • a folding mechanism and/or swivel mechanism and/or guide link mechanism and/or telescopic rail mechanism and/or ball bearing mechanism and/or slide rail mechanism and/or length change mechanism is designed by means of a folding mechanism and/or swivel mechanism and/or guide link mechanism and/or telescopic rail mechanism and/or ball bearing mechanism and/or slide rail mechanism and/or length change mechanism .
  • the support can advantageously have at least one folding mechanism and/or pivoting mechanism and/or guide link mechanism and/or telescopic rail mechanism and/or ball bearing mechanism and/or slide rail mechanism and/or length changing mechanism.
  • this is not to be understood as limiting, so that any mechanism is also conceivable that includes any type of change in length and/or change in area to increase the contact surface.
  • the support is designed in several parts.
  • a support advantageously has at least one, even more advantageously at least two, pivotable fittings.
  • Support can be pivoted and / or folded so that the size of the support surface itself can be changed. For example, if the support is opened, the support surface increases. However, when folded for support, the support surface is reduced.
  • the support is advantageously folded up in the basic position to save space.
  • the support is advantageously folded out in the position of use in order to provide an enlargement of the support surface. This allows the user to sit comfortably for a longer period of time.
  • the support has at least two support sections. It is, for example, conceivable that at least one support section is designed to be changeable in position relative to another support section. In this way, the two support sections can form a common contact surface with one another in the basic position. They therefore lie against each other. This allows the support to be designed to be particularly compact.
  • the folding mechanism and/or pivoting mechanism are designed in such a way that a cuboid shape is formed in the folded state of the two support sections, for example in the basic position. In the simplest case, this means that the folded support sections form a common contact surface and are flush with one another.
  • the pivoted and/or folded support sections are not designed flush with one another.
  • Support section is designed to protrude from the further support section. This is advantageous because it allows the user to have a gripping option. For example, if a user grips the projection, he can simply pivot it about at least one pivot axis, advantageously several pivot axes. This will open the support.
  • the position of use is limited by position limiting means, for example a physical stop, and at the same time is also held in position by this stop.
  • at least one support section is fixed in position and only the further support section is designed to be pivotable. So one support section is pivoted relative to the other support section.
  • the support has at least one overstretchable fitting. This is particularly advantageous if a person sits on the support when it is in use. This can prevent breakage. In practice, it is often observed that users carelessly sit on the support, even though it is completely unsuitable for the corresponding weights. This leads to well-known supports for legs, feet or arms breaking and having to be replaced.
  • At least one overstretchable fitting Due to the at least one overstretchable fitting, it is possible for the first time that at least one support section is deflected again from the position of use, advantageously towards the ground. This allows the force introduced to be dissipated and the overstretchable fitting and in particular the support itself remains usable. It there is no damage to the support.
  • this application of pressure force has ended, it is easily possible to return the overstretched at least one support section so that the support itself can be returned to the basic position. This can be done manually by the user, for example. This guides the support section from the overstretched position of use back into the position of use. It is also conceivable that the return from the overstretched position of use can take place via the at least one control unit, for example motor-controlled.
  • the support advantageously has two overstretchable fittings which connect the two support sections with one another. This means that these fittings can perform the pivoting described above and at the same time ensure that the support as a whole is break-proof.
  • the at least one over-expandable fitting is designed in several parts. It has proven to be particularly advantageous if the at least one overstretchable fitting is designed in four parts.
  • one link is arranged on a support section.
  • the other two links arranged between them which can also be referred to as middle links, have the pivot axes.
  • at least one middle link has at least one stop.
  • the over-expansion can advantageously be designed as a form fit and/or force fit and/or friction fit.
  • pivoting can be initiated up to a predeterminable locking point.
  • the support section snaps into place there and is overstretched Position of use secured. This is advantageous because there is then no undesirable snapping back with the termination of force application.
  • the return to the position of use can then be done manually, for example by releasing the locking point. In the simplest case, this can be done by pressing a button or by applying tensile force. The rest point is released and the support section is returned. This can also be done using spring element support.
  • the pivoting mechanism can be designed to increase the contact area.
  • the overstretchable fitting has at least one position limiting means, for example a stop. This stop reflects the final position of use and ensures that the transfer from the folded state of the support sections to the unfolded state of the support sections takes place in a predetermined and safe manner. Pivoting beyond the stop is not possible. This limits the pivoting movement.
  • the folded-out support section is lowered towards the ground via a further pivot axis. This is done by pivoting. This means that the acting force can be absorbed and dissipated via the pivoting movement. This prevents the overstretchable fitting from breaking.
  • the force can also be absorbed, for example, via a suitable spring element. This is advantageous because it also uses the restoring force can be used to eliminate the overstretch and return the support section back to the usual position of use.
  • the design is not limited to a spring element, so that other materials with a restoring effect can also be used.
  • a motorized return to the position of use is also conceivable.
  • the support surface is continuous and/or divided when in use.
  • the support surface which is advantageously formed by the two support sections, to be continuously covered with a material, so that a continuous support surface is formed.
  • the support surface itself is designed to be split and thus also has a split material cover. This makes it possible, for example, to place legs and feet more comfortably.
  • the support also has at least two guide rails.
  • Each guide rail advantageously has an elongated hole which specifies the movement path of a guide element at least partially arranged therein.
  • Each guide element advantageously has at least one projection which can be guided within the elongated hole.
  • Each guide element also has a support section advantageously at least partially pivotally connected.
  • a change in position of the guide element for example via the at least one drive unit, also causes a change in position of the support sections designed to be coupled to one another.
  • the movement path is determined by the shape of the elongated hole F.
  • the elongated hole Towards one end, the elongated hole has a section that is angled upwards. This advantageously has an angle relative to the horizontal in the range of 5°-45°, more advantageously of 10°-35°, particularly advantageously of 20°, with tolerances of ⁇ 2° being within the permissible range.
  • the guide elements are each advantageously designed as a parallelogram guide, so that the support section arranged thereon is always guided in parallel. This ensures that the support section in the use position is aligned parallel to the plane of the basic position. This is not to be understood as limiting, so it is also conceivable that an inclination of the support sections in the position of use is specified via the guide elements.
  • an advantageous component of the present invention is a control unit for controlling the support, the control unit controlling at least one drive means through which the support can be moved from a basic position to a use position and vice versa.
  • the drive means is designed as a motor.
  • the control unit is part of the edition. The control can take place, for example, via controls of a seat and/or reclining piece of furniture, via a remote control and/or via a software application for smartphones.
  • the control unit can receive, process, store, control and/or execute signals, data and/or commands.
  • the Control unit can be designed as a chip, processor or the like.
  • the control unit also advantageously controls and regulates the signaling during the delivery mechanism. For example, when the guide elements reach a predetermined position, this can trigger at least one acoustic signal and/or vibration signal. The user who has taken a seat on the seating and/or reclining furniture notices this signal and is informed that the support is extending.
  • a delivery mechanism has advantageously been established for this purpose. This delivery mechanism changes the position of the support from the basic position to the use position and vice versa.
  • Step c. is advantageous because it makes the user aware that the cushion is placed underneath the seat. It is conceivable that during the bringing out of the advantageous folded Support, a stop mechanism is provided if resistance is encountered. This is intended to prevent injuries to users. The movement will only continue when activated again.
  • step a can also be used here. and b. can be exchanged with each other so that the drive means is activated first and the support surface of the support is then reduced. This is the case, for example, when the reduction in the support surface is controlled and carried out using drive means.
  • the present invention also relates to seating and/or reclining furniture with at least one support according to the invention. It has proven to be particularly advantageous if the present invention is used in upholstered furniture, for example sofas, couch areas, upholstered furniture sets. Of course, this also includes armchairs.
  • seating furniture such as chairs or other table furniture that has such a support.
  • the present invention also relates to the use of the support according to the invention in seating and/or reclining furniture.
  • the present invention also relates to the use of the support according to the invention as a leg rest and/or footrest and/or armrest and/or backrest and/or headrest of a piece of seating and/or reclining furniture.
  • the present invention also relates to the use of the transfer mechanism explained above for changing the position of the leg rest, foot rest, armrest, headrest and/or backrest of a seating and/or reclining piece of furniture.

  • This seat 2 has a support in the basic position. In the illustration shown here, only a guide element 4 of support 1 is visible.
  • the support 1 is arranged compactly below the seat 2. Due to the padded seat surface 2, the mechanics, ie guide rails with guide recesses, guide elements, drive unit, racks and shaft with gears, are partially hidden and not visible.
  • Fig. 1a shows a perspective view obliquely from above of the support 1 of a piece of seating and/or reclining furniture (not shown here) in a basic position, the basic position being the most compact position in which the support 1 is arranged completely folded up below the seat 2.
  • the fitting as the support can also be referred to, has a pair of parallel guide rails 6, with which the support 1 is mounted in a linearly displaceable manner.
  • the displacement takes place via a drive unit 8, which in the embodiment shown is designed as a motor, advantageously as an electric motor.
  • the rotation of the shaft 10 causes a linear movement of the rack via the gears and consequently also a linear movement in the guide rails 6, with which the support 1 connected to it can be moved.
  • the guide rails 6 advantageously have a guide opening F, which reflects the movement of the support 1.
  • a linear course is specified after a short incline.
  • the elongated hole F is designed to run obliquely upwards. This reflects the lifting.
  • the linear movement may be effected using a worm gear or a screw drive instead of a rack and pinion mechanism.

  • Edition 1 is in the in Fig. 2 shown illustration from the basic position, as in Fig 1 shown, shifted linearly in the direction of arrow P, advantageously forward.
  • This drive means (not shown) enables the support 1 to be moved out of the basic position, initially in a linear, rectilinear manner in the direction of arrow P.
  • support 1 is moved linearly in the direction of arrow P below the seat surface 2 in a compact, here example folded, state.
  • Fig. 2a a perspective view is shown diagonally from above onto a support 1 in an intermediate position.
  • the intermediate position is characterized by the fact that the edition is 1 is shifted from the basic position.

  • the upper support section 12 is advantageously designed to be pivotable relative to the lower support section 14 via the fitting 100.
  • Both sections 12, 14 form a common contact surface 13 with one another. This is advantageous because it enables a compact arrangement of the support 1. At the same time, this common contact surface 13 prevents the user's fingers from potentially becoming trapped between the sections 12, 14. In this way, injuries can be successfully avoided.
  • the fittings 100 are designed in several parts. They advantageously have two pivot axes (not shown here). Furthermore, they have at least one stop 18, which limits the pivoting path.
  • Fig. 3a shows a perspective view obliquely from above of a fitting of a piece of seating and/or reclining furniture with a support 1 in a further intermediate position, the further intermediate position being characterized by the fact that the support sections 12, 14 are fully extended and at the same time out of the plane of the basic position protrudes, that is, arranged above it and displaced parallel to it.

It can be seen that by pivoting the second support section 12 upwards/forward, the support surface itself can be significantly enlarged. This is made possible via pivot axis A1, A2, which run through both fittings 100. A double-axis pivoting is thus formed.
