In addition, the solar bed is equipped with a solar roof, which is equipped with several photovoltaic modules. The solar bed is designed, among other things, for easy transportability and can be used, for example, as a bicycle trailer. The electrical energy supplied by the solar roof can be used to charge a battery. Ultimately, on the one hand, the supply or charging of low-voltage electrical appliances are to be made possible.

Despite the devices already known, there is still a need for electrically adjustable sunbeds with increased comfort and wider usability.

Presentation of the invention

The object of the invention is therefore to provide an improved electrically adjustable sun lounger. This object is achieved by the defined in claim 1 electrically adjustable sun lounger.

The inventive sun lounger has a frame and a lying surface fixed to the frame for a person, wherein the frame has lateral longitudinal elements, wherein the lying surface comprises at least a head part, a central part and a foot part, wherein the foot part on a fusswärtigen side of the central part and the head part a head-side side of the central part are pivotally connected to the central part, wherein the lying surface is adjustable in a range of positions; which comprise at least one first position for a lying position of the person and a second position for a sitting position of the person.

The couch is designed such that during the transition from the first to the second position, the head part is pivoted relative to the central part so that the Angle (β) between the two parts is reduced at the top of the bed and the foot part relative to the central part is pivoted so that the angle (α) between the two parts is reduced at the bottom of the bed, the frame with a first, second and third axes of rotation are arranged parallel to each other transversely to the longitudinal direction of the sun lounger, wherein the first axis of rotation is connected to the foot part and the second axis of rotation is connected to the central part and the third axis of rotation is connected to the head part, and wherein the sun bed an electrically operable adjusting device for setting a desired position in said region has.

According to the invention, the sun bed has at least one solar module, which is capable of supplying energy to a rechargeable electrical storage of the adjusting device, and the sun bed is also weatherproof, wherein at least the adjusting device and all existing bearings are encapsulated against environmental influences.

The term "sunbed" in the present context is a reclining furniture to understand that outdoors, especially under sunlight is usable. According to the invention, the sunbed is also "weatherproof", ie, all materials used for the construction should always be chosen so that even after several years in the open air neither color changes nor material damage such as embrittlement, rusting and the like occur. It goes without saying that the sunbed must be brought into the interior or under roof neither at rainfall and storm nor overnight. To ensure these advantageous properties, the entire sunbed is made from high quality weatherproof materials such as suitable steels (stainless steel), aluminum, suitable wood types, textiles and plastics. These materials are to be equipped according to the expertise with the necessary protective layers, impregnations and the like. Furthermore, all existing bearings as well as the adjustment are encapsulated against environmental influences.

As used herein, the term "pivot" is to be understood as meaning also angular changes about a horizontal axis of rotation, i. With a pivoting movement, changes in the angle of inclination are to be understood in particular.

The lying surface comprises at least a head part, a middle part and a foot part, these designations, as usual, designating those sections on which, as a rule, the head, torso or lower legs and feet come to rest in the case of a full-grown person. The lying surface is selectively adjustable in a range of positions, these positions include at least a first position for a lying position of the person and a second position for a seated position of the person. The first position thus corresponds to an arrangement in which the head, middle and foot part are substantially parallel to one another and overall lie largely in one plane. It is understood, however, that the individual parts of the lying surface do not have to be planes in the strict geometric sense and in particular are deformable due to a certain flexibility. In the second position, the head part is erected, the three parts seen laterally take an S-shape. As also illustrated below with reference to drawings, in the transition from the first to the second position, the head part relative to the central part is pivoted so that the angle (β) between the two parts is reduced at the top of the bed and the foot part relative to the middle part so pivoted so that the angle (α) between the two parts on the underside of the bed is reduced. In order to enable this adjustability, the frame is provided with a first, second and third axis of rotation, which are arranged parallel to each other transversely to the longitudinal direction of the sun lounger. Here, the first axis of rotation is connected to the foot part, the second axis of rotation connected to the middle part and the third axis of rotation connected to the head part. The term "connected" is not limited to rigid connections, but in particular also includes connections that are formed via intermediate links and joints.

By electrically operable adjusting the desired position of the sun lounger can preferably be continuously, but at least at small angular intervals as they are convenient for the user, adjusted.

Thanks to a variety of equipment and configuration options, the inventive sun lounger can be used in a variety of ways. In addition to pure relaxation, in which primarily the advantageous mechanical configuration of the sun lounger comes to fruition, the solar-powered electrical supply offers numerous options from entertainment (audio, video, gaming) to the "home office" work with laptop and the like. But it is also the interaction of mechanical flexibility, weather resistance and solar-powered electrical supply, which results in a maximum of comfort and possible uses.

The invention is based on the use of a solar module, i. a planar arrangement of photovoltaic elements. Such modules are basically known and commercially available. Weatherproof embodiments are available, inter alia, for shipping. Instead of a solar module or in addition to this could be provided in principle, another type of module such as a wind or water energy winning module.

Advantageous embodiments of the invention are defined in the dependent claims.

Depending on requirements, the sunbed can be equipped with only one or more solar modules. In the following, the singular number "the solar module" will generally be used, meaning that several solar modules can be meant accordingly. The solar module can be fastened at different locations on the couch, for example laterally on the frame, wherein a wide variety of fastening principles can be used. It is expedient in this case that the electrical connection to be ensured between the solar module and the rechargeable memory (Also known as accumulator or "battery") is available in a suitable, weatherproof design. According to one embodiment (claim 2), the solar module is hinged to the head part. On the one hand, this makes it easy for the user to align with the position of the sun and can also be used as a shade dispenser. Preferably, the solar module can be adjusted manually or electrically in its position or orientation. In one embodiment, the orientation of the electrically adjustable solar module by means of a control device can be automatically adapted to the position of the sun, in particular to compensate for shifting, turning or tilting of the solar bed. It is also advantageous (claim 3), if the solar module is removable, which should preferably be possible without tools, so as to operate, for example, from the sunbed external electronic devices or at least to charge their battery can.

With the combination of a suitable solar module and a battery, a sufficient supply autonomy can normally be ensured. Nevertheless, it may be appropriate (claim 4) to equip the electrical storage with an additional alternating voltage charging device. In particular, it can be achieved if necessary, a quick charge or recharge of the battery.

It is also advantageous (claim 5), when the electrical memory supplies not only the adjusting device, but also other electrical connections. These include, but are not limited to, for example, various interfaces and / or outputs such as e.g. USB and other connections for operating accessories such as fans, speakers, lighting, shading elements and privacy screens. In addition, the electric storage can also be used to supply an electric drive for locomotion of the sun lounger.

Devices for adjusting the inclination of sunbeds and other similar furniture are basically known. In an advantageous embodiment of Invention (claim 6), the adjusting device on a mechanical or hydraulic or pneumatic adjusting unit and an associated pressure generating unit. For example, so that a controlled, controlled linear motion can be generated, which fulfills the desired purpose of the adjustment. It is expedient (claim 7) when the adjustment cooperates with a remote control. In this case, different variants come into question. Thus, the remote control can be cable-based, wherein expediently the required cable is arranged in the frame and the remote control is embedded in the frame or it can be clipped on it. Alternatively, however, wireless remote controls with signal transmission by radio or "Bluetooth" or infrared can be used. In certain embodiments, the remote control may also be used to control the orientation of the solar module.

The adjusting device could in principle be positioned at different locations of the couch. Advantageous (claim 8) is for reasons of weight, but also with respect to the weather protection, when the adjusting device is mounted below the lying surface on the frame.

According to an advantageous embodiment (claim 9), the frame has at least a pair of axially spaced casters, which produce a bearing ground contact with one-sided raised frame and have no contact with the ground when the frame is not raised. This can be caused on the one hand by a comparatively small amount of force displacement of the sun lounger, on the other hand, however, an undesired rolling in the non-raised state is avoided. The size and the material of the rolls depend on the desired area of application or the ground conditions.

To further increase in particular for a comfortable reading operation, it is advantageous (claim 10), when the head part is formed in two parts, with a terminal Section of the head part with respect to the remaining part of the head part is tilt-adjustable.

• das Fussteil ist an ein einteiliges Schwenkglied angelenkt, das um die erste Drehachse des Rahmens schwenkbar angeordnet ist,
• das Mittelteil ist mit seitlichen Längsschlitzen versehen ist, in welchen die zweite Drehachse des Rahmens dreh- und verschiebbar aufgenommen ist, und
• das Kopfteil ist um die dritte Drehachse des Rahmens schwenkbar angeordnet; und
• das zweite Ende des längsverstellbaren Elementes ist über ein gewinkeltes Schwenkglied mit dem Kopfteil verbunden.

In a further embodiment (claim 11), the adjusting device has a longitudinally adjustable between a retracted and an extended position element, which is articulated at its first end to the frame and at its second end to a part of the lying surface. By combining these with suitable rotary axes and joint elements, the desired coordinated adjustment of the foot part, middle part and head part can be achieved by a simple linear movement. Advantageously (claim 12), the adjustability of the lying surface is ensured by the following compounds:

• the foot part is articulated to a one-piece pivot member which is pivotally mounted about the first axis of rotation of the frame,
• the middle part is provided with lateral longitudinal slots, in which the second axis of rotation of the frame is rotatably and slidably received, and
• the head part is pivotally mounted about the third axis of rotation of the frame; and
• the second end of the longitudinally adjustable element is connected via an angled pivot member to the head part.

According to a particularly advantageous embodiment of the sun bed (claim 13), at least one laterally hinged to the headboard armrest is present, which is hinged about a hinged axis between an unfolded and a retracted position and has a remote from the folding axis free end. Preferably, the armrests are in pairs, with independent folding capability being preferred. Below, however, the Einzahlform is used and is in two existing armrests to understand analogously. Particularly advantageous in the embodiment mentioned here is that the armrest in the unfolded position regardless of the position of the sun lounger, ie from the horizontal position to the sitting position, always substantially parallel points to the ground. Thus, the person on the sun lounger is not unnecessarily obstructed and can namely move the legs laterally under the folded-out armrest. In the folded-in position, moreover, the armrest is oriented essentially parallel to the head part from the folding axis to the free end of the head part; In any case, it is aligned so that it does not interfere with the side and entry of the person from and to the sun lounger.

In an advantageous embodiment (claim 14), the unfolded and also the folded position of the armrest are defined by abutting lateral projections of the armrest against corresponding stop surfaces. The latter are optionally adjustable, for example in the form of setscrews.

Ways to carry out the invention

The figures show an embodiment of the invention. For clarity, the individual components are not provided in all figures with reference numerals.

The electrically adjustable sun lounger shown in the figures comprises a frame 2 and a lying surface 4 attached to the frame for a person. The frame has lateral longitudinal elements 6. The lying surface comprises at least a head part 8, a middle part 10 and a foot part 12, wherein the foot part on a fusswärtigen side 14 of the middle part and the head part on a kopfwärtigen side 16 of the central part are pivotally connected to the central part.

The lying surface is adjustable in a range of positions; the at least one first position, hereinafter also "lying position", for a lying position of the person and a second position, hereinafter also "sitting position" for a seated position of the person include. The couch is designed so that in the transition from the lying position in the sitting position, the head part is pivoted relative to the middle part so that the angle (β) between the two parts is reduced at the top of the bed and the foot part is pivoted relative to the middle part, that the angle (α) between the two parts at the bottom of the bed is reduced.

The frame is provided with a first axis of rotation A, a second axis of rotation B and a third axis of rotation C, which are arranged parallel to each other transversely to the longitudinal direction of the sunbed, wherein the first axis of rotation is connected to the foot part and the second axis of rotation is connected to the central part and the third axis of rotation is connected to the head part.

The sunbed is equipped with an electrically operable adjusting device 18 for setting a desired position in said area. The adjusting device comprises a rechargeable electric storage 20, hereinafter also referred to as "battery". In the example shown, the adjusting device is mounted below the lying surface on the frame. Furthermore, the sun bed comprises at least one solar module 22, which is capable of powering the battery. The sun lounger is weatherproof, wherein at least the adjusting device, but also all existing bearings, some of which are exemplified by the reference numeral 24, encapsulated against environmental influences.

In the example shown, the solar module 22 is hinged to the head part 8 and can thereby be adjusted with respect to its inclination. In certain embodiments, the solar module can also be completely folded. Preferably, the solar module via not shown here connectors is electrically connected to a supply line leading to the battery.

As in particular from the FIGS. 5 and 6 can be seen, the adjusting device 18 is a longitudinally adjustable between a retracted and an extended position Element 26 which is articulated with its first end 28 on the frame and with its second end 30 on a part of the lying surface.

• das Fussteil 12 ist an ein einteiliges Schwenkglied 32 angelenkt, das um die erste Drehachse A des Rahmens schwenkbar angeordnet ist,
• das Mittelteil 10 ist mit seitlichen Längsschlitzen 34 versehen ist, in welchen die zweite Drehachse B des Rahmens dreh- und verschiebbar aufgenommen ist,
• das Kopfteil 8 ist um die dritte Drehachse C des Rahmens schwenkbar angeordnet; und
  das zweite Ende 30 des längsverstellbaren Elementes 26 ist über ein gewinkeltes Schwenkglied 36 mit dem Kopfteil verbunden.

Like from the Fig. 7 and 8th recognizable, the adjustability of the lying surface is ensured in the embodiment shown by the following compounds:

• the foot part 12 is articulated to a one-piece pivot member 32 which is pivotally mounted about the first axis of rotation A of the frame,
• the middle part 10 is provided with lateral longitudinal slots 34, in which the second axis of rotation B of the frame is accommodated in a rotatable and displaceable manner,
• the head part 8 is pivotally mounted about the third axis of rotation C of the frame; and
  the second end 30 of the longitudinally adjustable element 26 is connected via an angled pivot member 36 with the head part.

• eine vierte Drehachse E ist starr am Rahmen angeordnet, sodass die dritte Drehachse C und die vierte Drehachse E in einem definierten Winkel gegenüber der Horizontalen ausgerichtet sind;
• an der vierten Drehachse E ist ein zweiteiliges Schwenkglied 42 mit einer fünften Drehachse F angeordnet, das an die Klappachse D am Kopfteil befestigt ist;
• das Ganze ist so konfiguriert, dass die Verbindungen CD und EF gleich lang sind, wodurch die Verbindungen CE und DF stets parallel sind.

Like also from the FIGS. 5 and 6 clarifies, an armrest 38 is articulated laterally on the headboard. Each armrest is hinged about a hinged axis D between an unfolded and a retracted position. Each armrest has a remote from the folding axis D free end 40, wherein the armrest in the unfolded position, regardless of the position of the sun lounger is always substantially parallel to the ground. This is achieved in the present example by the following arrangement:

• a fourth axis of rotation E is rigidly arranged on the frame, so that the third axis of rotation C and the fourth axis of rotation E are aligned at a defined angle relative to the horizontal;
• on the fourth axis of rotation E, a two-part pivot member 42 is arranged with a fifth axis of rotation F, which is fixed to the folding axis D on the head part;
• the whole thing is configured so that the connections CD and EF are the same length, whereby the connections CE and DF are always parallel.

The unfolded and folded position of the armrest is like in the Fig. 10 and 11 clarified by striking lateral projections 44a, 44b of the armrest against corresponding stop surfaces 46a, 46b, which are optionally adjustable, defined at the section DF.

Advantageously, the frame has at least a pair of axially spaced casters 48. Like from the Fig. 11 can be seen, each caster comes with one-sided raised frame in contact with the ground, thereby producing a bearing ground contact. It is understood that this helps to roll the sun lounger. In contrast, the role of not raised frame has no contact with the ground, which improves the stability against unwanted slippage of the sun lounger.
