Description

[0001] The present invention relates to a seating and reclining furniture, advantageously in the form of a wave lounger, with a multi-part substructure comprising a backrest mounted thereon, a seat surface and a leg rest adjoining the seat surface, and with a floor frame on which the substructure is rotatably mounted, according to the preamble of claim 1.

[0002] Seating and reclining furniture with a backrest and a seat with leg rests is already known in the art; these are referred to as recliners, forest sofas, wave loungers, or sky loungers. The lying surface of this seating and reclining furniture consists of parallel wooden slats spaced apart from each other, which are attached to a base frame and follow the shape of the base frame. It is common for the base frame to have a wave shape, which in turn gives the seating and reclining surface created by the wooden slats a wave-like form. The known base frames are mostly made of steel or wood. Furthermore, seating and reclining furniture referred to as recliners, forest sofas, wave loungers, or sky loungers is known that can rotate 360° around an axis of rotation. The aforementioned seating and reclining furniture can be stationary, in which case a foundation is necessary for its attachment.In addition to a swivel function, the familiar seating and reclining furniture also offers other functions, such as adjusting the backrest relative to the seat surface and, for example, rocking and swinging functions.

[0003] For example, DE 20 2022 001 197 U1 discloses a reclining chair with an ergonomically shaped wooden lying surface, interrupted in the middle to serve as the pivot point for the backrest. The reclining chair is suitable for two people. The backrest can be adjusted to the desired reclining position using a spring-loaded adjustment mechanism, operated by a foot pedal. The adjustment mechanism uses locking positions, with the foot pedal releasing the chair from one locking position, allowing the backrest to then be adjusted to lock into another position. The design of the adjustment mechanism ensures that the backrest always locks securely into each position, thus providing the reclining chair with a stable, vibration-free, and safe resting position for the user.

[0004] Patent 20 2020 003 032 U1 discloses a sky lounger with a continuous wooden lying surface physiologically adapted to the human body shape. The lounger is suitable for one or more people. Mounted on a rotating column, the lounger can be continuously adjusted and held in position. Optionally, the lounger can also be continuously tilted around a horizontal axis and locked in any position, allowing the user to freely choose their preferred position in relation to the sun. The described arrangement of joints and the selection of suitable machine elements are designed to ensure an equally stable, vibration-free resting position in any orientation.

[0005] Finally, DE 10 2015 000 307 A1 relates to a stationary, rotatably mounted parking lounger. To ensure a defined force is applied to the rotation of the lounger and to counteract the risk of accidents due to excessively rapid rotation, a circular friction surface is applied to at least one stationary foot support. A lounger support exerts pressure on the friction surface with the weight of the lounger positioned above it and possibly a certain additional weight force. Since the lounger support is connected to the lounger above it, the lounger can only be rotated with a certain minimum force. Due to the weight force, the friction surface generates high friction against the opposing surface of the lounger support, thus making it more difficult for the lounger support to rotate in the opposite direction to the foot support.

[0006] For the purposes of this patent application, the term "seating and reclining furniture" shall also include beach chairs. Such beach chairs offer excellent weather protection, which is why they were initially extremely popular in coastal regions, particularly in public areas, for tourist rental. Beach chairs are also very popular in private settings, so when used in gardens, they can also be referred to as garden beach chairs. More generally, for the purposes of this patent application, the term "seating and reclining furniture" encompasses both indoor and outdoor use. Outdoors, the seating and reclining furniture according to the invention can be used in both private and public areas.

[0007] A general disadvantage of familiar seating and reclining furniture such as loungers, forest sofas, wave loungers, or sky loungers is their limited or no adjustability. This limitation is particularly important in public areas to prevent injuries. Furthermore, adjusting the position of these pieces of furniture, for example, to follow the sun, requires the user to get out of the chair. For private use, these pieces are only suitable to a limited extent, as they require a foundation for installation. This foundation also precludes protected storage during the autumn and winter months. Disclosure of the invention

[0008] The object of the invention is to improve, at least partially, seating and reclining furniture known from the prior art. In particular, the object of the present invention is to design seating and reclining furniture, especially in the form of a wave lounger or a forest sofa, which allows for orientation, for example following the position of the sun, i.e., rotation of the seating and reclining furniture, as well as for tilt adjustment of the seating and reclining furniture by a user without the user having to leave the seating and reclining furniture.

[0009] The foregoing problem is solved by a seating and reclining furniture, advantageously in the form of a wave lounger, with the features of claim 1.

[0010] Further advantages, features and details of the invention will become apparent from the dependent claims; further advantages and details of the invention will also become apparent from the description and the drawings.

[0011] The seating and reclining furniture according to the invention, advantageously in the form of a wave-shaped lounger, with a multi-part substructure comprising a backrest mounted thereon, a seat surface and a leg rest adjoining the seat surface, and with a base frame on which the substructure is rotatably mounted, incorporates the technical teaching that the rotation of the substructure relative to the base frame is effected via a turntable in the form of a perforated disc and wherein the perforated disc is rotationally connected to a handwheel, wherein a shaft is arranged on the handwheel, at the end of which a gear is non-rotatably connected to the shaft, and wherein the gear engages in the perforated disc in such a way that, when the handwheel and the gear connected to it via the shaft are actuated, the substructure can be rotated.

[0012] For a better understanding of the present invention, it is divided into a backrest, a seat with an adjoining leg rest. However, as can be seen from the exemplary embodiment according to the figures, the seat can be divided, with one part merging into the backrest and the other part of the seat being integrally formed with the leg rest.

[0013] The right-hand handwheel with locking pin, as shown in the figures, allows the seating and reclining furniture according to the invention to be rotated 360° in all directions. Power transmission is advantageously achieved by friction and / or positive locking via a gear and a perforated disc with a hole spacing of 12°. The locking pin is preferably spring-loaded and automatically engages at the end of a rotation, thus fixing the desired position.

[0014] Advantageously, the seating and reclining furniture according to the invention, designated by the applicant as the "RoWaldsofa," consists of a construction made of laser-cut and / or rolled profiles with and without material doubling, wherein the profiles can be connected to one another by means of fasteners or by folding or crimping connections. Advantageously, the laser-cut profiles are mounted by means of screw connections or by means of rivet connections, which considerably simplifies assembly for a private user. Welding connections can thus be completely eliminated. The elimination of welding connections also has the advantage that all components can be painted or powder-coated, for example, after their profiling in the cutting or rolling process. Overall, the "RoWaldsofa," namely the seating and reclining furniture according to the invention, therefore offers a simple construction.

[0015] Starting from a basic (seated) position, the "RoWaldsofa" can be conveniently tilted to any position, up to a fully reclined position, using a lockable gas spring. Alternatively, any fluid-actuated spring can be used, such as a hydraulic spring with an oil-damped cylinder. For clarity, the term "lockable gas spring" will be used in the following text.

[0016] To release the gas spring from a locked or blocked position, a release button is pressed, which advantageously activates a mechanism with a Bowden cable. This allows the lockable gas spring to be securely locked in any desired position within its entire stroke. The reclining position can optionally be preset before using the "Ro-Waldsofa" or adjusted during use.

[0017] The RoWald sofa's reclining surface comfortably accommodates two people. Of course, smaller or even larger reclining surfaces are also conceivable, accommodating one or more than two people.

[0018] Preferably, the RoWaldsofa is designed to be freestanding without a foundation connection, using a floor frame, which allows for freely selectable and repositionable placement at any desired location (horizontal, up to a maximum 2% slope).

[0019] When placing the RoWaldsofa on the lawn, the base can be advantageously designed with a surrounding impact protection for robotic lawnmowers.

[0020] For storage, the RoWald sofa, namely the seating and reclining furniture according to the invention, can be brought into the basic position, in order to then fold up the seat part with the integrated side cushion, so that the RoWald sofa occupies a compact space-saving footprint.

[0021] Preferred embodiments: Further measures improving the invention are described in more detail below with reference to the figures and preferred embodiments of the invention. The features and details of the invention mentioned in the claims and in the description can be essential to the invention individually or in any combination. It should be noted that the embodiments shown in the figures are for descriptive purposes only and are not intended to limit the invention in any way.

[0023] In the different figures, identical parts are always marked with the same reference symbols, which is why they are usually only described once.

[0024] The Fig. Figure 1 shows a side view of a seating and reclining furniture 1 according to the invention in the form of a wave lounger 10 in a basic position, also referred to as the sitting position. The wave lounger 10 comprises a multi-part substructure 2 with a backrest 3 mounted thereon, a seat 4, and a leg rest 5 adjoining the seat 4. The seat 4, or at least a part of the seat 4, is mounted with the adjoining leg rest 5 on part 2.4 of the substructure 2. In the embodiment of a seating and reclining furniture 1 according to the invention in the form of the wave lounger 10 shown here, the backrest 3, the seat 4, and the leg rest 5 adjoining the seat 4 are formed from spaced-apart wooden slats, which are mounted on the left and right sides on two parallel and spaced-apart longitudinal beams 2.1 and 2.2 of the substructure 2.Instead of wooden slats, other materials are also conceivable, such as a flexible material like sheet metal or a flexible wood or plastic panel. A slatted frame made of plastic or metal slats would also be possible. Due to the foldable design of the wave lounger 10, the longitudinal beams 2.1 and 2.2 running lengthwise along the substructure 2 are divided, with one part 2.1.1 and 2.2.1 of each beam 2.1 and 2.2 serving to form the backrest 3, and the other part 2.2.1 and 2.2.1 of each beam 2.1 and 2.2 serving to form the seat 4 with the integrated leg rest 5. The substructure 2 is connected via a base 30 to a turntable 6 in the form of a perforated disc 60 with holes 60.1 spaced apart from each other following the radius of the perforated disc 60 (see detailed view in ). Fig. 4), rotatably mounted on a base frame 20. Part 2.3 of the substructure 2, with the backrest 3 mounted on it, is supported on the base 30 by a lockable gas spring 23 with a progressive compression spring 23.1 and a fluid-filled pressure piston 23.2. A handwheel 7 is arranged to the side of the seat surface 4, in the figure at the front center of the wave lounger 10, and below the seat surface 4. This handwheel is connected to a gear 7.3 via a shaft 7.1 in a rotationally fixed manner. The gear 7.3 engages in the holes 60.1 of the perforated disc 60 via its pinions, at least by friction and / or positive locking. The distance between the holes 60.1 of the perforated disc 60 corresponds to the distance between the pinions of the gear 7.3. When the handwheel 7 is actuated, namely when the handwheel 7 is turned, the shaft 7.1 and the gear 7.3 attached to the end of the shaft 7.1 rotate, whereby the gear 7.3 engages in the holes 60 via the pinions by means of at least force-fit and / or form-fit engagement.The handwheel 7 rotates the perforated disc 60, the perforated disc 60, the base 30 connected to the perforated disc 60, and thus the multi-part substructure 2 connected to the base 30 with the backrest 3, the seat 4, and the leg rest 5 adjoining the seat 4. The rotation of the substructure 2 relative to the base frame 20 via the handwheel 7 is advantageously stepless and variable by 360° clockwise and counterclockwise. This means that the wave lounger 10 can be rotated by a user sitting or lying on it by 360° clockwise and counterclockwise, for example, to follow the position of the sun. An advantageously rotatable locking pin 7.4 is arranged on the handwheel 7 itself. Due to the rotatable mounting of the locking pin 7.4, it also functionally serves as a rotary handle for the handwheel 7.4 is also preferably designed as a compression spring element by means of a spring, so that at the end of a rotation process it automatically engages in a detent position in a hole 7.2 provided in the handwheel 7, thereby fixing the desired position of the wave lounger 10. On the side opposite the handwheel 7, at the rear in the figure, a storage table 70 with a horizontally oriented tabletop 70.1 is connected to the base 30 via a table leg 70.2 in the area and above the seat surface 4 in such a way that when the substructure 2 with the backrest 3 mounted on it, the seat surface 4 and the leg rest 5 integrated therein is moved from the basic position to a freely selected reclining position (see . Fig. 2) the tabletop 70.1 always remains horizontally oriented. The tabletop 70.1 is connected to the table leg 70.2 via two legs 70.3 that can pivot relative to each other. The legs 70.3 allow the tabletop 70.1 to pivot and extend over the seat 4 (in the figure, the direction of movement of the tabletop 70.1 over the legs 70.3 is from back to front). To the right above the handwheel 7, a release mechanism 40 with a release button 41 is arranged on the substructure part 2.3 with the backrest 3 mounted on it. The release button is advantageously connected to a Bowden cable 42 (schematically shown in the figure). Fig. (6 shown), which in turn activates a further release and locking mechanism (not shown) for the lockable gas spring 23, allowing the lockable gas spring 23 to be released for a lifting movement and securely locked in any desired position along its entire stroke by locking or blocking the gas spring 23. This allows the entire wave lounger 10 to be tilted into any desired position and held in that position. The base frame 20 comprises a base plate 20.2 with feet 20.1 arranged around its perimeter, enabling the seating and reclining furniture 1, preferably designed as a wave lounger 10 or forest sofa, to stand freely without requiring a foundation. A collision guard 200 for robotic lawnmowers is arranged around the base plate 20.2 above the feet 20.1. The collision guard 200 is particularly well-suited as a continuous, closed ring in the Fig. 3, Fig. 4 and Fig. 7 to recognize. The Fig. Figure 2 shows a side view of the seating and reclining furniture 1. Fig. 1 which, via the release mechanism 40 with the release button 41, has been moved from the basic position to a lying position to activate the gas spring 23 in a lifting movement. Since the seating and reclining furniture 1, designed in the form of the wave lounger 10, is centrally balanced or supported above the base frame 20, the secure stand via the foundation-free base frame is maintained even when the wave lounger 10 is tilted into the lying position.

[0025] In the Fig. Figure 3 shows the seating and reclining furniture 1 from the previous figures in a perspective view from a slightly oblique angle above, looking at the side where the side table 70 is mounted on the base 30 via the table leg 70.2, rotated approximately 180°. The tabletop 70.1 of the side table 70 is positioned towards the seat 4 and can be pivoted and extended along the legs 70.3 parallel to the slats of the seat 4. The side table 70 remains in a horizontal position or with the tabletop aligned even when the wave-shaped lounger 10 is moved into its position.

[0026] In the Fig. Figure 4 shows a detailed top-down view of the rotary mechanism 300 with the rotary disk 6 in the form of the perforated disk 60 and the gear 7.3, which is actuated via the shaft 7.1 by the handwheel 7. Radially circumferential holes 61 are formed in the perforated disk 60, into which the pinions of the gear 7.3 engage, at least by friction and / or positive engagement, and thus, when the gear 7.3 is rotated via the shaft 7.1 and the handwheel 7 connected to the shaft 7.1, causes the rotary disk 6 to rotate. The spacing of the holes 61 corresponds to the tooth pitch (pinion) of the gear 7.3, at least by friction and / or positive engagement. The gear ratio between the handwheel 7 and the detent bolt 7.4, the gear 7.3 and the perforated disc with the radially circumferential and spaced-apart bore holes 61 is advantageously 5°. A detent disc 7 is located behind the handwheel 7 with the detent bolt 7.4.5 arranged, into which the locking bolt engages at least force-fit and / or form-fit in order to fix the selected rotational position (see . Fig. 7).

[0027] The Fig. Figure 5 shows a detailed side view of the seating and reclining furniture 1 from the previous figures, focusing on the handwheel 7 and the lockable gas spring 23. Above the handwheel, the location of the release button 41 for the release mechanism 40 is also visible. The handwheel 7 can be rotated both clockwise and counterclockwise via the locking pin 7.4, which is designed as a rotary handle (indicated in the figure by the opposing arrows).

[0028] Fig. 6 shows the one in Fig. Figure 4 shows a detailed view from the rear of the rotary mechanism below the substructure 2 for mounting the seat 4 or the backrest 3. The detailed view clearly shows how the gear 7.3 engages via a pinion in a hole 60.1 of the rotating disc 6, which is designed as a perforated disc 60, at least by friction and / or positive engagement. This causes the base 30 to rotate via the shaft 7.1 and the attached handwheel 7, through the perforated disc 60. Additionally, a Bowden cable 42 is schematically shown for the release mechanism 40, which activates the gas spring 23 from its blocked position to a release or lifting position. The release button 41 is connected via the Bowden cable 42 to a release and locking mechanism, which is advantageously a mechanism of the gas spring 23.

[0029] The Fig. Figure 7 shows a detailed view of the detent disc 7.5 located behind the handwheel 7. A complete rotation of the handwheel 7 results in a rotation of approximately 50° due to the gear ratio between the perforated disc 60 and the gear 7.3. The 12° division of the detent disc 7.5 corresponds to a rotation of approximately 2°.

[0030] Finally, the Fig.Figure 8 shows a perspective view from a slightly oblique angle of above of the seating and reclining furniture 1 in the form of a wave lounger 10 from the previous figures in a folded state. Part 2.4 of the substructure 2, with the seat 4 and integrated leg rest 5 mounted on it, is pivoted relative to part 2.3 of the substructure 2, with the backrest 3 mounted on it, via a pivot joint such that the seat 4 with the integrated leg rest 5 is inclined in the same direction as the backrest 3. This configuration offers a space-saving storage size, for example, to protect the seating and reclining furniture 1 from weather damage by storing it in a shed or garage. Furthermore, folding the seating and reclining furniture 1 as shown can also be used to, for example, mow the lawn around it, on which the seating and reclining furniture 1 rests via the base 20.Finally, it should be mentioned that the seating and reclining furniture 1, in the folded position shown, can still be rotated via the handwheel 7 and its inclination can be adjusted by the release mechanism 40 through activation with the release button 41.
