Definitions

  • the present invention relates to reclining furniture according to the preamble of patent claim 1.
  • reclining furniture is known from the prior art, in which the spring element has spring legs bent in a C-shape.
  • Such recliner furniture are also known as cantilever chairs.
  • the US 2011/0260507 A1 shows a generic reclining furniture, which is specially designed for babies.
  • the lying surface is supported on a base by means of a coil spring.
  • the coil spring is located in a housing which limits the maximum deflection of the coil spring in an adjustable manner.
  • Other generic loungers are in the US 5,615,428 A and in the US 6,574,806 B1 shown.
  • the FR 1 300 265 and the WO 2014/134467 A1 show sprung seating.
  • the object of the invention is to improve a piece of reclining furniture of the type mentioned above in such a way that it better promotes the sleeping and / or resting process of the person lying on the lying surface.
  • the invention proposes a reclining furniture according to claim 1.
  • the invention provides that an additional limiting element keeps the spring element carrying the lying surface in an elastically prestressed state even in the unloaded state. This enables the lying surface to vibrate at a lower frequency than in the prior art when a person lies down on the lying surface. This promotes both sleeping and sleeping through the person lying on the lying surface or can at least have a relaxing effect on them.
  • the reclining furniture can have one or more feet.
  • the pedestal or pedestals are the components of the reclining furniture that lie directly on the surface on which the reclining furniture is placed in the normal operating position. In the case of several feet, these are preferably arranged in one plane.
  • the substructure can in principle be designed very differently in the case of loungers according to the invention.
  • the substructure supports the lying surface and for this purpose has at least one base and at least one elastic spring element arranged between the base and the lying surface.
  • the limiting element is also preferably a component of the substructure that is additional to the spring element.
  • the limiting element can be designed, for example, as a belt or loop be.
  • the unloaded state is the state in which the substructure only bears the weight of the reclining furniture. In the unloaded state, there is neither a person nor any other load on the lying surface.
  • the lying surface is the component of the lying furniture on which the person lies down.
  • the support surface that is to say the surface of the lying surface on which the person ultimately lies, can also be designed to be curved. It is preferably provided, for example, that the support surface of the lying surface has a depression for the buttocks area and an increase as a backrest and an increase as a knee pad.
  • the lying surface or the support surface can be curved, for example, approximately S-shaped or the like.
  • the limiting element advantageously limits the deflection of the lying surface in the unloaded state in the direction away from the base.
  • the reclining furniture can also have a stop element for limiting a deflection of the lying surface in the direction of the base in the loaded state.
  • the loaded state is a state in which an additional mass, such as a person using the reclining furniture, lies on the lying surface.
  • the elastic prestressing of the spring element according to the invention means that the spring element in the loaded state is still suitable, on the one hand, for carrying correspondingly large additional masses, such as correspondingly heavy people, and, on the other hand, can vibrate in this state at a relatively low frequency. This ensures low-frequency swinging that has a particularly sleep-promoting and relaxing effect on the reclining furniture. It is particularly preferred in the case of reclining furniture according to the invention that the lying surface is arranged in the unloaded state in a starting position and in a loaded state with an additional mass lying on the lying surface, preferably of 85 kg, in an intermediate position deflected relative to the starting position.
  • the spring element is thus advantageously designed so that the intermediate position is reached after placing the additional mass on the lying surface.
  • the lying surface in the loaded state around the deflected intermediate position can swing freely.
  • the fact that the lying surface can swing freely around the deflected intermediate position in the loaded state means that the lying surface swings out in the form of a free damped vibration after a single deflection in the loaded state.
  • the spring element is expediently designed such that the vibration from the intermediate position without additional drives is only excited by the person lying on the lying surface. It is particularly preferably provided that only the breathing of the person is sufficient to excite the vibration of the lying surface together with the additional mass lying on it in the form of a person.
  • the pretension according to the invention which is held by the limiting element in the unloaded state, has the advantage that the intermediate position can be reached from the starting position with a relatively short spring deflection of the spring element and the desired vibration is then possible. Without prestressing, a very wide or strong deflection into the intermediate position would have to be accepted in order to then be able to carry out the desired vibrations. This would lead to a very shaky, difficult to control construction, which is prevented by the bias according to the invention.
  • the reclining surface with an additional mass of 85 kg lying on the reclining surface after a single deflection from a rest position towards the base with a free vibration following the deflection has an oscillation frequency between 0.1 and 1 Hertz. Since the free oscillation after a single deflection is a so-called natural oscillation of the system consisting of reclining furniture and additional mass, one could also speak of the natural frequency as the oscillation frequency. In the rest position from which the deflection for excitation of the subsequent free oscillation takes place, one could also speak of the intermediate position in the preferred exemplary embodiments mentioned above. The ratio of inertia and spring stiffness is decisive for the vibration frequency.
  • the spring element has a relatively low vibration damping.
  • preferred variants of reclining furniture according to the invention provide that the reclining surface with an additional mass of 85 kg lying on the reclining surface after a single deflection from a rest position in the direction of the base with a free oscillation following the deflection has an amplitude maintenance greater than or equal to 20% , wherein the amplitude maintenance is calculated from the ratio of an amplitude of the sixth oscillation period after deflection to an amplitude of the second oscillation period after deflection.
  • after deflection means that the oscillation periods are counted from the beginning of the free oscillation. While the first oscillation period is usually still strongly influenced by the deflection or the oscillation excitation, the second oscillation period is usually already that of a free damped oscillation.
  • the pretension and also the other elastic properties of the spring element are advantageously chosen in such a way that it is ensured that neither the limiting element nor the stop element which may be present disturb this free oscillation.
  • the spring element of the reclining furniture according to the invention can be designed very differently.
  • Preferred variants provide that the at least one spring element has two spring legs which are connected to one another in a connection area.
  • the spring legs can be arranged to diverge at least in regions, starting from the connection region.
  • the legs are particularly preferably arranged one above the other in the operating position of the reclining furniture. It is possible, for example, for the stand (s) to be arranged on the lower spring leg, while the lying surface is on the bed, either directly or with the interposition of the adjustment device mentioned further below the upper spring leg of the spring element rests.
  • the two spring legs can, but do not have to be integrally connected to one another in the connection area.
  • the connection area can, for example, be C-shaped.
  • the connecting area is advantageously arranged under or next to the half of the lying surface facing the foot end.
  • the spring legs then advantageously diverge at least in regions in the direction towards the head end of the lying surface.
  • the substructure of the reclining furniture according to the invention can have exactly one spring element but also several spring elements. Particularly preferred variants of the invention provide that the substructure has exactly two spring elements. These can be arranged at a distance from one another on opposite sides of the lying surface. Each of these spring elements can be designed in accordance with the preferred embodiment variants mentioned above.
  • the lying furniture has an adjusting device for adjusting the lying surface relative to the spring element in mutually opposite longitudinal directions of the lying surface.
  • This adjustment device makes it possible to reach the intermediate position and also to set the oscillation frequency of vibrations of the lying surface in the loaded state for different additional masses or persons of different weights, that is to say also those that deviate from 85 kg. In this way, the desired oscillation frequency can also be set for people of different weights, that is to say additional masses lying on the lying surface.
  • the adjustment device is therefore a possibility of adapting the function to the weight of the person lying on the lying surface.
  • the adjustment of the lying surface by means of the adjustment device does not necessarily have to take place in exactly horizontal, opposite longitudinal directions of the lying surface.
  • the longitudinal directions in which the adjustment device can adjust the lying surface relative to the spring element advantageously have at least one horizontal component in the operating position.
  • the Adjustment device is advantageously designed to be lockable.
  • the adjusting device enables the lying surface to be adjusted relative to the spring element, but on the other hand also allows the respectively set position to be locked.
  • the adjusting device is designed to be self-locking or self-locking, that is to hold the position that has been set on its own without an additional measure having to be taken.
  • the adjusting device is advantageously arranged between the substructure and the lying surface, preferably between the spring element and the lying surface.
  • the adjustment device is advantageously designed to be free of play. When locked, it should guarantee a quasi-rigid connection between the lying surface and the substructure.
  • the adjustment device can be designed differently. E.g. it can be a kind of sledge.
  • the adjustment device can e.g. have at least one gear for engagement in at least one rack.
  • worm drives, hydraulic or pneumatic piston-cylinder arrangements or other linear drives known per se could just as well be used.
  • the adjustment device is expediently adjustable by hand. But they are also motor e.g. Variants of adjusting devices driven by an electric motor are conceivable.
  • the invention also relates to the use of a reclining furniture according to the invention, which is characterized in that a person lies down on the lying surface and thereby the lying surface from a starting position, which takes up the lying surface in an unloaded state, into a position relative to the starting position deflected intermediate position is deflected and the lying surface with the person lying thereon is set, starting from the intermediate position, into a vibration which is only stimulated by the breathing of the person.
  • the lying surface is favorably influenced neither by the limiting element nor by the stop element that may be present.
  • the vibration stimulated by the breathing of the person is advantageously in the range between 0.1 and 1 Hertz, that is in the range of the above-mentioned natural frequencies or vibration frequencies of a free vibration. Due to the excitation that takes place by means of the person's breathing, a natural frequency range of the system consisting of reclining furniture and the person lying on it is excited, so that the low forces and accelerations that occur during breathing are sufficient to excite the vibration. It has been shown that relatively low vibration amplitudes are sufficient to achieve the calming or sleep-promoting effect of the reclining furniture according to the invention. An adjustment to the respective weight of the person lying on the lying surface in order to reach the intermediate position can be carried out with preferred reclining furniture with the above-mentioned adjustment device.

  • the substructure 3 has two spring elements 5 arranged parallel to one another and opposite one another on the lying surface 2, as is particularly well shown in FIG Fig. 4 you can see.
  • Each of these spring elements 5 has two spring legs 13 and 14, the spring leg 13 being arranged above the spring leg 14 in the operating position shown.
  • the feet 4 are arranged on the lower of the spring legs 14.
  • the upper spring leg 13 carries the lying surface 2, the adjusting device 16 being arranged in the preferred variants shown here between the substructure 3 or the respective upper spring legs 13 and the lying surface 2.
  • the two spring legs 13 and 14 are connected to one another in a connecting region 15 of the respective spring element 5.
  • the connection area 15 is C-shaped in this exemplary embodiment.
  • the connection area 15 is directed towards the foot end 50 of the lying surface 2.
  • the spring legs 13 and 14 run towards Head end 43 of the lying surface 2 apart at least in regions.
  • the adjustment device 16 is designed like a slide and allows the lying surface 2 to be adjusted in the longitudinal directions 17 relative to the substructure 3 or to the spring elements 5 and the feet 4. This is largely a horizontal adjustment, which, as said above, but also can have vertical components.
  • the structure of the adjusting device 16 of the exemplary embodiments shown here is explained below with reference to FIG 4 to 6 explained in more detail.
  • the spring elements 5 elastically pretension the lying surface 2 in the direction 6 away from the base 4 or the base 4.
  • the lying surface 2 is in, in 1 and 2 Unloaded state shown is held elastically biased by a limiting element 7 of the reclining furniture.
  • This elastic pretension could be demonstrated by the fact that if the limiting element 7 were released, the lying surface would be deflected further away from the spring feet 4 in the direction 6 from the feet 4 than in the initial position according to FIG 1 and 2 is the case in the unloaded state.
  • the limiting element 7 is a kind of stop, which holds the spring elements 5 in the prestressed state even when the lying surface 2 is unloaded.
  • the two lower spring legs 14 of the two spring elements 5 are rigidly connected to one another via a stop bracket 20.
  • the opposite end of the limiting element 7 is connected to a component of the adjusting device 16 which is fixedly connected to the upper spring legs 13.
  • the limiting element 7 could of course also be connected in a different way to the spring legs 13 and 14 in order to keep the spring elements 5 elastically biased even in the unloaded state.

  • a stop element 8 is also provided in addition to the limiting element 7. This limits the deflection of the lying surface 2 in the loaded state in the direction 9 towards the base 4. In the event of an overload or an excessive load on the lying surface 2, the stop element 8 thus prevents the spring element 5 from being destroyed or otherwise negatively influenced by overloading.

  • the adjustment device 16 can be used for weight adjustment.
  • the 1 and 2 show the starting position of the lying surface 2 in the unloaded state. If you now place an additional mass 10, for example in the form of a Fig. 3 Person stylized on the lying surface 2, a stressed state is reached in which the lying surface 2 together with the additional mass 10 lying thereon is deflected into an intermediate position. In Fig. 3 the intermediate position is solid shown. The starting position according to Fig. 2 is in Fig. 3 shown in dashed lines. It should be noted that the in Fig. 3 schematically illustrated person or additional mass 10 lies in the position provided for the use of the lying furniture 1 on the lying surface 2 by the head of the person near the head end 43 and the feet of the person near the foot end 50 of the lying surface 2 .
  • the intermediate position shown with a solid line allows the lying surface 2 together with the person or additional mass 10 lying thereon to execute a free oscillation or a oscillation which is forced by the breathing of the person and which, with a correspondingly adapted oscillation amplitude, is neither influenced by the limiting element 7 nor by the stop element 8.
