Definitions
- the present invention relates according to claim 1 to an ergonomically adjustable reclining device for one or more people with different body dimensions.
- a conventional, non-ergonomic lounger usually has only a limited level of adjustability (approx. 4 positions) between sitting and lying position or an adjustability that takes a lot of effort. In addition to the inconvenience, it is often difficult or awkward to leave the position you have already assumed without having to get up from the bed.
- the kink or the axis of rotation is only in the back area and causes back tension or pressure points when leaning for a long time, which can only be avoided by adding a cushion or an upholstered pad.
- the object of the present invention to provide a device for the variable adjustment of the position between a substantially horizontal position and a
- the device should be designed so that it is easy and inexpensive to manufacture and allows adaptation to different body sizes.
- the device comprises a right and a left side part, each of which is made up of at least an outer side part and an inner side part, a backrest element and a seat surface element, which are rotatably connected to one another via a first bearing stock, and a Foot part element which is rotatably connected to one another via a second bearing block with the seat surface element, the foot part element being mounted via a third bearing block between the right and left side parts, the first, second and third bearing blocks each in a corresponding guide is mounted translationally movable in the right and left side parts in such a way that the backrest element, the seat surface element and the foot part element are variably adjustable between a substantially horizontal position and an ergonomic sitting position, and the first bearing block via a locking slide in a lock gsausfräsung is locked in at least one outer side part by self-locking, and wherein the self-locking can be canceled by the user via a hand knob, and the seat surface element is constructed in such a way that the seat depth is achieved by
- the ergonomic lying device according to the invention because of the interconnected elements, which can each be moved translationally in a corresponding guide in the right and left side part, when the user presses the hand knob, the self-locking is canceled and the Lying device between the seated ergonomic position and the lying ergonomic position can be adjusted continuously variably. It is particularly advantageous that, due to the self-inhibition, the user does not need to take any action in order to maintain the ergonomic position that has been assumed. About that In addition, it is not necessary for the user to get up from the lying device according to the invention if the lying device is to be variably adjusted between the seated ergonomic position and the lying ergonomic position, since the user only has to operate the hand knob in order to adjust the position continuously.
- the reclining device enables the additional guide slots in the construction parts forming the seat surface, in which guide rods run for the length adjustment of the seat surface and, in the case of a guide rod with a slider placed opposite on the outside with an inclined slot for self-locking, that the length of the Seat is variable and preferably continuously adjustable.
- the first bearing stock extends through an arcuate cutout of the inner side part and is guided and moved in a long hole of the slide for variable adjustment of the position between a substantially horizontal position and an ergonomically seated position, if the self-locking is canceled by means of the hand knob.
- the slide is guided in a guide in the side part, so that the movement of the slide is guided from two sides and the self-locking is thereby facilitated.
- the locking slide is displaced by actuating the hand knob in the locking recess, canceling the self-inhibition, with self-locking being generated by wedging the locking slide in the locking recess when the user does not operate the hand knob .
- the backrest element is mounted between the right and left side parts such that it can rotate about an axis of rotation, the axis of rotation and the first bearing block determining the position of the backrest element.
- the horizontal lying position by the The axis of rotation and the uppermost position of the first bearing stock is defined particularly simply, and the second and third bearing stock are also in the uppermost position thereof.
- a first rod, a second rod and a third rod are provided between the right and the left side part for stabilization, which together form a triangle, and wherein the first and third rod form the base of the triangle and each represent the inclusion of a wheel for rolling movement of the couch or to roll the couch over the floor.
- the first and third rod form the base of the triangle and each represent the inclusion of a wheel for rolling movement of the couch or to roll the couch over the floor.
- Fig. 1 shows a perspective schematic overall view of the lying device 10 according to the invention with rungs 140 (see Fig. 6 ) the ergonomic lounger, where the outside 60 (see Fig. 5 ) and indoor 80 (see Fig. 5 ) Side parts are shown as transparent.
- the reinforcements (wooden strips) 160 see Fig. 7 ), which after the rungs 140 (see Fig. 6 ) into the notches 98 (see Fig. 6 ) of the side parts 90/130 (see Fig. 5 ) (Detail 150, see Fig. 6 ) are glued onto this (see Fig. 7 ) in order to guarantee the strength of the backrests (prevention of bending fractures due to excessive loads).
- Fig. 2 shows in perspective the already assembled lying surfaces (backrest 23, seat 24 and foot part 25) in different positions (but without the interaction between the outer 60 (see Fig. 5 ) and indoor 80 (see Fig. 5 ) Side parts and slider 70 (see Fig. 5 ).
- the sitting position 20 is shown with the back part 23 raised, the seat surface 24 lowered and the foot part 25 angled.
- the half-reclining position 21 is shown with an inclined backrest 23, half-raised seat surface 24 and half-raised foot part 25.
- the lying position 22 is with a horizontal backrest 23, horizontal seat 24 and horizontal foot part 25 shown. Any position between these extremes can also be set and is held in this position by means of the self-inhibiting function described below.
- the self-locking is created by the interaction of the following components bearing stock 102 (see Fig. 5 ), an arcuate or 1 ⁇ 4-circular cutout 82 (see Fig. 5 ), Slide 70 with associated long hole 71 (see Fig. 5 ) and the hand knob 50/51 (see Fig. 5 ), as well as the milled guides or locking recess 61 in the outer side part 60 and the milled guide 81 in the inner side part 80 (see Fig. 5 ).
- the self-inhibition is based on the friction principle. That is, the slide 70 with its obliquely milled long hole 71 (see Fig. 5 ) is supported by the bearing stock 102 (see Fig. 5 ) either pushed up or down, depending on the load or relief of the seat. When loading the seat downwards, when relieving the seat upwards. This is via the form fit of the slide 70 (see Fig. 5 ), with the upper or lower edge of the cutout 61 in the side part 60 (see Fig. 5 ) creates friction between these surfaces.
- the slide 70 like two wedges facing each other, but connected to one another, which are located between the bearing block 102 (see Fig.
- the self-locking is also functional if the principle is reversed 180 ° and the roles (active and passive) of the components are swapped. Ie - the bearing block 103 (active) does not exercise on the slide 344 (passive), or as in Figure 16c and 16d on the slide 513 (passive) or slide 518 (passive) a push / push movement, but vice versa - the slide 344 (active), or as in Figure 16c and 16d the slide 513 (active) or slide 518 (active) exert a push / push movement on the bearing block 103 (passive). In general, only the role (active and passive) of the components changes, but the basic principle remains. It is only important that a small "play" is provided for the respective reactive component (passive) (either slide or bearing block) in order to enable the jamming.
- This functionality sets the present couch apart from many mechanical couches available on the market, since it does not require any action on the part of the user to maintain the assumed position.
- This inhibition is achieved in that the bearing block 102 through the 1 ⁇ 4-circular milled recess 82 (see Fig. 5 ) up to the long hole 71 (see Fig. 5 ) or 261 (see Fig. 4 ) of slide 70 (see Fig. 5 ) or 260 (see Fig. 4 ) enough.
- This long hole 71 (see Fig. 5 ) or 261 (see Fig. 4 ), which the slide 70 (see Fig. 5 ) or 260 (see Fig. 4 ) is actually divided into two opposing wedges, blocks the free movement of the bearing block 102 (see Fig. 5 ) in the 1 ⁇ 4-circular cutout 82 (see Fig. 5 ) by the fact that the long hole 71 (see Fig. 5 ) or 261 (see Fig. 4 ) in its alignment almost always perpendicular to the 1 ⁇ 4-circle direction of movement (up or down) of the bearing block 102 (see Fig. 5 ) stands.
- the curved cutout 82 of the inner side part 80 are omitted.
- the self-locking is not generated by a 1 ⁇ 4-circular movement, but by a push / push movement of the bearing block 103 on the slide 344, or as in Figure 16c and 16d on slider 513 or slider 518.
- This principle is also used when adjusting the length of the seat surface (see Fig. 19 ), with slide 535 (see Figures 18b and 18c and Fig. 19 ), the guide stick 532 (see Figures 18a, 18c and Fig.
- the two flanks of the slot are not made parallel, but have different slopes.
- a flat angle is used to adjust the friction to the maximum or as required depending on the application.
- a steep angle is used in order to adjust the friction to a minimum or, depending on the application, to adjust it. This creates an asymmetrical sequence of movements, which enables the full braking effect (self-locking) in one direction and maximum sliding (very little or no self-locking) in the opposite direction.
- FIG. 3 shows a side section through the bed, with components shown transparently, in order to show schematically this interaction of the aforementioned components in the three different positions (but without the interaction with the slide 70 (see Fig. 5 ).
- the sitting position 30, the half-reclining position 31 and the horizontal reclining position 32. Can be seen very clearly in FIG Fig. 3 how the lever position of the backrest, which changes over the three positions (here as an example side part backrest 90 (see Fig. 5 ), which extends over the axis of rotation in hole 88 (see Fig. 5 ) in the inner side part 80 (see Fig. 5 ) or stock 101 ( Fig. 5 ), the articulation between the backrest 23 (see Fig. 2 ) and seat 24 (see Fig. 2 ) changes.
- the long hole 83 in the inner side part 80 serves on the one hand as a bearing for the joint connection (bearing block 104 (see Fig. 5 )) between seat 24 (see Fig. 2 ) and foot part 25 (see Fig. 2 ) and on the other hand as a guide for this.
- Fig. 4 shows, with components shown transparently, also a lateral section through the bed in order to show schematically the interaction of the aforementioned components in the three different positions, but is limited to the illustration of the variant of the slide 260 (see FIG Figure 11b ), a section of the alternative outer side part 210 (see Fig.10b ) with cutout 211 (see Figure 10b ), the side view of the bed frame and the section through the armrest 180 (see Figure 9b ).
- the three main positions of sitting 40, half-lying 41 and lying 42 are also shown here. You can see here very nicely how the slide 260 (see Figure 11b ) migrates from right to left when moving from the sitting position 40 to the half-lying position 41 and finally to the horizontal lying position 42.
- the armrest 180 (see Figure 9b ) is always pushed away by the user of the lounger when he / she stretches out, when the user of the bed 24 (see Fig. 2 ) and simultaneous loading of the backrest 23 (see Fig. 2 ) above the pivot point 88 (see Fig. 5 ) the slide 260 (see Figure 11b ) via the joint connection (bearing block 102 (see Fig. 5 )) relieves the burden and thus removes self-inhibition.
- the user relaxes and lets the armrest 180 (see Figure 9b ) briefly and the slide 260 (see Figure 11b ) wedged by the pressure of the bearing block 102 (see Fig.
- Fig. 5 shows a schematic exploded view of the bed with all the individual parts relevant to the function (provided with numbers and without for the sake of clarity Rungs 140 (see Fig. 6 ) and reinforcements (wooden strips) 160 (see Fig. 7 ) of the backrest side parts 90/130 (see Fig. 5 ).
- Fig. 6 shows the lying surface frame shown in perspective with back, seat and foot part as well as the respective individual parts with waiver of the entirety of the rungs 140, their insertion into the recess 98 (see Fig. 5 ) of the side part 90 (see Fig. 5 ) is shown schematically as an assembled section 150.
- the individual parts 90, 91, 92 are shown in side view and top view.
- the bearing blocks are shown in perspective using 100, 110 as an example.
- the rungs 140 are also shown in side and plan views and in perspective.
- FIG. 7 Figure 10 shows the reinforcement 160 in side, top and perspective views.
- the reinforcement 160 is also shown in combination with the side part 90 of the backrest 23 (see FIG Fig. 2 ).
- FIG. 6 shows the assembly of the reinforcement 160 with the cutout 150 using wood glue.
- Fig. 8 shows a simplified perspective view of the static construction, with the round bars 110, 111, 112 attached between the inner side parts 80, viewed from the side, each spanning an imaginary triangle that ensures the lateral stability of the bed.
- a wheel 121 is shown which, when pushed over the round bars 110 and 112 by means of the central hole (one wheel on the left and one wheel on the right), offers the possibility of easier mobility of the bed.
- the possible variants without wheel 170, with wheel 171 or different variants of the wheel suspension 172, 173, 174 and 175 are also shown as sections A / B.
- Figure 9a shows the actuation knob 50/51 attached to the side for the slide 70 (see Fig. 5 ) as individual parts 50 (knob) and connecting part 51 for insertion into the slot 72 (see Fig. 5 ) of slide 70 (see Fig. 5 ) and in perspective as a merged view.
- Figure 9b shows the armrest 180 for operating the slide 260 (see Figure 11b ) as a side and top view, as well as section A / B with the recess for receiving the connecting webs 262 (see Figure 11b ).
- Figure 9c shows the crank 190 for the alternative actuation of the modified slide 270 (see Figure 11c ) with toothing 272 (see Figure 11c ) with the individual parts crank handle 191, crank center shaft 192, crankshaft 193 and gear 194.

- the present invention relates to the infinitely variable adjustability and self-locking of the ergonomic bed (kink points are on the one hand in the hip area and on the other hand in the knee area and not in the back area as with other beds and without knee bend) which cross each other due to the Directions of movement of the slide 70 (see Fig. 5 ) (horizontal) and the stock 102 (see Fig. 5 ) (1 ⁇ 4 circle - or vertical, movable connection between backrest and seat) block each other.
- the oblique long hole 72 required for this (see Fig. 5 ) in slide 70 (see Fig. 5 ) to hold the bearing block 102 (see Fig.
- the foot section is also lowered with the present lounger in the sitting position and there is another bend in the user's knee area. This prevents tension and strain on the knee joint.
- This is achieved through the oblique guide long holes 84 (see Fig. 5 ) in the inner side parts 80 (see Fig. 5 ) and the connection of the backrest 23 (see Fig. 2 ) with the seat 24 (see Fig. 2 ) and the foot part 25 (see Fig. 2 ) by means of the bearing blocks 102, 103 and 104 (see Fig. 5 ), which on the one hand connect these lying surfaces with one another and at the same time act as supports in the respective long guide holes 83 (see Fig. 5 ) serve.
- the pivotal point is the bearing stock 101, which is firmly glued in the back part and located in the bearing hole 88 (see Fig. 5 ) in the inner side part 80 (see Fig. 5 ) can rotate.
- the bath towel can slip off the backrest and must be laboriously brought back into position.
- the top rung as a loose round bar 100 (see Fig. 5 ) of the lying device according to the invention, which is in the holes 97/137 (see Fig. 5 ) of the two side parts 90/130 (see Fig. 5 ) is freely movable, you can with or without removing (threading in the bath towel) the round rod 100 (see Fig. 5 ) simply fold the bath towel over and it does not slide down when the lounger is raised into the sitting position.
- the lounger according to the invention can be made in different materials such as metal, wood, plastic, ceramic, hard paper, cardboard and rattan as well as different shapes, colors and designs. Depending on the material and design, the lounger according to the invention can be used both indoors and outdoors, since it works without electricity.
- the side parts or frames of the bed according to the invention can be designed differently depending on the material and thus also have an impact on the storage areas (see Figure 15b ) or the type of slide used (for variants see Figure 15a , Figure 16c and 16d ) and on the static elements (in wooden design round bars 110, 111, 112 or boards) that are connected to the inner side parts 80 (see Fig. 8 ) create an imaginary triangle.
- bearings depends on the material and can be made of wood as a simple support or with a metal insert (e.g. brass, self-lubricating), roller bearings, slide bearings or journal bearings. This also applies to the position or alignment of these bearings (see Figure 15b ).
- a metal insert e.g. brass, self-lubricating
- roller bearings slide bearings or journal bearings. This also applies to the position or alignment of these bearings (see Figure 15b ).
- the lying areas shown in rung design, depending on the material used, simple boards, rungs, pipes, rods, a Covering (including plastic, textiles, leather, wire, wire wrapped in paper, ropes, cords or plant fibers) or a grid, a mesh, a perforated sheet or plates which may also be provided with recesses.
- the present wooden lounger is designed in such a way that all connections are only made with galvanizing. This is on the one hand very ecological and on the other hand very advantageous for the manufacturing process. However, the connections can also be made with screws in order to realize simpler constructions that do not require galvanization. In any case, screw or welded connections are sensible for metal couches.
- a support on the lying surface is appropriate, which is either a commercially available foam u. Covered with fabric, leather or cork. o. latex mat, or a layer made of woven sheep's wool which can be easily attached to the back with a Velcro fastener. Of course, you can also use a normal bath towel. Roll pads can also be used in the neck, back or knee area.
- the present invention relates to a lying device for the variable adjustment of the position between a substantially horizontal position and a ergonomic sitting position, as in the Figures 1 to 16 shown, the seat length adjustment is not shown, but which in the following Figures 17 to 22 is shown and explained in detail. It is readily apparent to a person skilled in the art that the length adjustment of the seat surface as in particular in FIG Figure 17 c also shown on the embodiments of the reclining devices Figures 1 to 16 can be transferred.
- a flat angle is used to adjust the friction to the maximum or as required depending on the application.
- a steep angle is used in order to adjust the friction to a minimum or, depending on the application, to adjust it. This creates an asymmetrical sequence of movements, which enables the full braking effect (self-locking) in one direction and maximum sliding (very little or no self-locking) in the opposite direction.
- the variant with the stepless seat length adjustment 534 (see Figure 17b ) by means of external locking slide 535 (see Figure 18b ) as in the interaction of these components (see Figure 18c and Fig. 19 ) showed the possibility of stepless adjustment to different body sizes (e.g. a child, a woman, a man of normal height or a very tall adult) without even having to get up from the bed.
- the seat surface parts 530 and 531 see FIG Figure 18c and Fig. 19
- the guide slots 536 and 537 in connection with the guide rods 532 and 533, which continuously create a self-locking through the locking slide 535.

Description
Die vorliegende Erfindung bezieht sich gemäß Anspruch 1 auf eine ergonomisch verstellbare Liegevorrichtung für eine oder mehrere Personen mit unterschiedlichen Körpermaßen.The present invention relates according to
Eine herkömmliche nicht ergonomische Liege, hat meist nur eine begrenzte stufige Verstellbarkeit (ca. 4 Positionen) zwischen Sitz- und Liegeposition bzw. eine kraftaufwendige Verstellbarkeit. Neben der Unbequemlichkeit ist es oft schwierig bzw. umständlich die bereits eingenommene Position wieder zu verlassen ohne von der Liege aufstehen zu müssen.A conventional, non-ergonomic lounger usually has only a limited level of adjustability (approx. 4 positions) between sitting and lying position or an adjustability that takes a lot of effort. In addition to the inconvenience, it is often difficult or awkward to leave the position you have already assumed without having to get up from the bed.
Bei vielen verstellbaren Liegen, die nicht ergonomisch ausgeführt sind, ist der Knick bzw. die Drehachse nur im Rückenbereich und verursacht bei längeren Anlehnen Rückenverspannungen bzw. Druckstellen, die lediglich durch zusätzliche Auflage eines Kissens bzw. einer gepolsterten Auflage vermeidbar sind.With many adjustable loungers that are not ergonomically designed, the kink or the axis of rotation is only in the back area and causes back tension or pressure points when leaning for a long time, which can only be avoided by adding a cushion or an upholstered pad.
Es gibt zwar ergonomische Liegen, die aber zum Teil gar nicht oder nur bedingt verstellbar sind. Die Verstellbarkeit, dieser bekannten Liegen, ist meist kompliziert und aufwendig oder es wird ein Stromanschluss für den Motor benötigt. Somit sind diese bekannten Liegen auch nicht für jeden Standort im Freien (z.B. Strand oder Terrasse ohne Stromanschluss) geeignet.There are ergonomic loungers, but some of them are not or only partially adjustable. The adjustability of these well-known couches is usually complicated and expensive or a power connection for the motor is required. Thus, these well-known loungers are not suitable for every location outdoors (e.g. beach or terrace without power connection).
Bekannte Liegen sind zum Beispiel in den Dokumenten
Es ist somit die Aufgabe der vorliegenden Erfindung eine Vorrichtung zum variablen Verstellen der Position zwischen einer im Wesentlichen horizontalen Position und einer ergonomisch sitzenden Position bereitzustellen, wobei die Vorrichtung so gestaltet sein soll, dass diese einfach und kostengünstig herzustellen ist und eine Anpassung an verschiedene Körpergrößen ermöglicht.It is therefore the object of the present invention to provide a device for the variable adjustment of the position between a substantially horizontal position and a To provide an ergonomically seated position, the device should be designed so that it is easy and inexpensive to manufacture and allows adaptation to different body sizes.
Die zuvor genannte Aufgabe wird erfindungsgemäß durch eine Vorrichtung zum variablen Verstellen der Position zwischen einer im Wesentlichen horizontalen Position und einer ergonomischen sitzenden Position gemäß Anspruch 1 unter Bildung einer variablen Sitztiefenverstellung gelöst.The aforementioned object is achieved according to the invention by a device for the variable adjustment of the position between an essentially horizontal position and an ergonomic sitting position according to
Die erfindungsgemäße Vorrichtung umfasst dabei ein rechtes und ein linkes Seitenteil, welches jeweils zumindest aus einem Außen-Seitenteil und einem Innen-Seitenteil aufgebaut ist, ein Rückenlehnen-Element und ein Sitzflächen-Element, welche über einen ersten Lagerstock drehbar miteinander verbunden sind, und einem Fußteil-Element, welches über einen zweiten Lagerstock mit dem Sitzflächen-Element drehbar miteinander verbunden ist, wobei das Fußteil-Element über einen dritten Lagerstock zwischen dem rechten und linken Seitenteil gelagert ist, wobei der erste, zweite und dritte Lagerstock jeweils in einer entsprechenden Führung in dem rechten und linken Seitenteil derart translatorisch bewegbar gelagert ist, dass das Rückenlehnen-Element, das Sitzflächen-Element und das Fußteil-Element zwischen einer im Wesentlichen horizontalen Position und einer ergonomischen sitzenden Position variabel verstellbar sind, und wobei der erste Lagerstock über einen Arretierungsschieber in einer Arretierungsausfräsung in zumindest einem Außen-Seitenteil durch Selbst-Hemmung arretiert wird, und wobei die Selbst-Hemmung über einen Handknauf vom Benutzer aufhebbar ist, und wobei das Sitzflächenelement derart aufgebaut ist, dass die Sitztiefe durch zwei Führungsstangen, welche im Sitzflächenelement in Längsrichtung der Liegevorrichtung verschiebbar gelagert sind, variabel und stufenlos auf die Körpergröße einstellbar ist.The device according to the invention comprises a right and a left side part, each of which is made up of at least an outer side part and an inner side part, a backrest element and a seat surface element, which are rotatably connected to one another via a first bearing stock, and a Foot part element which is rotatably connected to one another via a second bearing block with the seat surface element, the foot part element being mounted via a third bearing block between the right and left side parts, the first, second and third bearing blocks each in a corresponding guide is mounted translationally movable in the right and left side parts in such a way that the backrest element, the seat surface element and the foot part element are variably adjustable between a substantially horizontal position and an ergonomic sitting position, and the first bearing block via a locking slide in a lock gsausfräsung is locked in at least one outer side part by self-locking, and wherein the self-locking can be canceled by the user via a hand knob, and the seat surface element is constructed in such a way that the seat depth is achieved by two guide rods, which in the seat surface element in the longitudinal direction of the lying device are slidably mounted, can be variably and continuously adjusted to the body size.
Diese Lösung ist insbesondere dadurch vorteilhaft, dass die erfindungsgemäße ergonomische Liegevorrichtung wegen der miteinander verbundenen Elemente, die jeweils in einer entsprechenden Führung in dem rechten und linken Seitenteil translatorisch bewegt werden können, bei Betätigung des Handknaufs durch den Benutzer die Selbst-Hemmung aufgehoben wird und die Liegevorrichtung zwischen der sitzenden ergonomischen Position und der liegenden ergonomischen Position stufenlos variabel verstellt werden kann. Besonders vorteilhaft ist es, dass es aufgrund der Selbst-Hemmung keiner Aktion des Benutzers bedarf, um die eingenommene ergonomische Position beizubehalten. Darüber hinaus ist es für den Benutzer nicht erforderlich von derer findungsgemäßen LiegeVorrichtung aufzustehen, wenn die Liegevorrichtung zwischen der sitzenden ergonomischen Position und der liegenden ergonomischen Position variabel verstellt werden soll, da der Benutzer lediglich den Handknauf betätigen muss, um die Position stufenlos variabel zu verstellen. Darüber hinaus ermöglicht die erfindungsgemäße Liegevorrichtung durch die in den die Sitzfläche bildenden Konstruktionsteilen zusätzlich eingebrachten Führungsschlitzen, in denen Führungsstangen für die Sitzflächen-Längenverstellung laufen und bei einer Führungsstange mit je einem gegenüberliegend außen aufgesetzten Schieber mit Schrägschlitz für die Selbst-Hemmung, dass die Länge der Sitzfläche variabel und bevorzugt stufenlos einstellbar ist.This solution is particularly advantageous in that the ergonomic lying device according to the invention, because of the interconnected elements, which can each be moved translationally in a corresponding guide in the right and left side part, when the user presses the hand knob, the self-locking is canceled and the Lying device between the seated ergonomic position and the lying ergonomic position can be adjusted continuously variably. It is particularly advantageous that, due to the self-inhibition, the user does not need to take any action in order to maintain the ergonomic position that has been assumed. About that In addition, it is not necessary for the user to get up from the lying device according to the invention if the lying device is to be variably adjusted between the seated ergonomic position and the lying ergonomic position, since the user only has to operate the hand knob in order to adjust the position continuously.

Im Folgenden werden verschiedene Aspekte der Erfindung anhand der Figuren erläutert.Various aspects of the invention are explained below with reference to the figures.
Die Selbst-Hemmung entsteht dabei durch das Zusammenspiel der folgenden Komponenten Lagerstock 102 (siehe
Die Selbst-Hemmung beruht auf dem Reibungs-Prinzip. D.h. der Schieber 70 mit dessen schräg eingefrästen Lang-Loch 71 (siehe
Die Selbsthemmung ist auch funktional, wenn man das Prinzip 180° umkehrt und die Rollen (Aktiv und Passiv) der Bauteile vertauscht. D.h. - nicht der Lagerstock 103 (Aktiv) übt auf den Schieber 344 (Passiv), bzw. wie in
Diese Funktionalität hebt die vorliegende Liege von vielen auf dem Markt verfügbaren mechanischen Liegen ab, da es keiner Aktion des Benutzers bedarf, um die eingenommene Position beizubehalten. Um das sich selbständige Verstellen der eingenommenen Position zu verhindern, ist die Bewegung des Lagerstocks 102 in der ¼-kreisförmige Ausfräsung 82 (siehe
Solange durch den Lagerstock 102 (siehe
Es gibt generell die Möglichkeit der symmetrischen Selbsthemmung mit Blockierung in beide Bewegungsrichtungen (mit parallel ausgeführten Flanken des Schräg-Schlitzes (71, 261, 271, 281, 291, 301) im Schieber (70, 260, 262, 270, 280, 290, 300, 321, 331, 344, 513, 518)) oder der asymmetrischen Selbsthemmung mit Blockierung in nur eine Bewegungsrichtung mit der bevorzugten Blockier-/Gleit-Richtung, welches sich durch unterschiedliche Winkel des Schlitzes (71, 261, 271, 281, 291, 301) im Schieber (70, 260, 262, 270, 280, 290, 300, 321,331, 344, 513, 518) für Schub-/Druck-Richtung auszeichnet. D.h. die beiden Flanken des Schlitzes sind nicht parallel ausgeführt, sondern weisen unterschiedliche Steigung auf. In Blocker-Richtung (Anlehnen an die Rückenlehne) kommt ein flacher Winkel zur Anwendung, um die Reibung maximal bzw. wie je nach Anwendung erforderlich einzustellen. In der entgegengesetzten Gleit-Richtung (Aufrichten aus der Sitzposition) kommt ein steiler Winkel zur Anwendung, um die Reibung minimal bzw. je nach Anwendung erforderlich einzustellen. Somit entsteht ein asymmetrischer Bewegungsablauf, der in einer Richtung die volle Bremswirkung (Selbsthemmung), und in der entgegengesetzten Richtung maximales Gleiten (sehr geringe oder gar keine Selbsthemmung) ermöglicht.
Die Einzelteile werden im Weiteren bezeichnet und die Detailansichten der
Diese Variante ist eine richtige Material- und Zeit-Sparvariante für die Fertigung, da der Schieber nicht wie bei den anderen Varianten eingehaust ist, sondern frei liegt und man nur ein Innen-Seitenteil verbaut.
This variant is a real material and time-saving variant for production, since the slide is not enclosed as in the other variants, but is exposed and only an inner side panel is installed.
Wie aus obigen Erläuterungen ersichtlich ist, betrifft die vorliegende Erfindung die stufenlose Verstellbarkeit und Selbstarretierung der ergonomischen Liege (Knickpunkte liegen einerseits im Hüftbereich und andererseits im Kniebereich und nicht wie bei anderen Liegen im Rückenbereich und ohne Knie-Knick) die sich aufgrund der sich kreuzenden Bewegungsrichtungen des Schiebers 70 (siehe
Neben dem richtigen Knick im Hüftbereich wird bei der vorliegenden Liege in der SitzPosition ebenso das Fußteil mit abgesenkt und es entsteht ein weiterer Knick im Kniebereich des Benutzers. Dies verhindert Verspannungen und Belastungen des Kniegelenks. Erreicht wird dies durch die schrägen Führungs-Lang-Löcher 84 (siehe
Ferner kann bei herkömmlichen Liegen erfahrungsgemäß beim Hinsetzen jeweils das Badetuch von der Rückenlehne verrutschen und muss umständlich wieder in Position gebracht werden. Durch die Ausführung der obersten Sprosse als loser Rundstab 100 (siehe
Die erfindungsgemäße Liege kann in verschiedenen Materialien wie Metall, Holz, Kunststoff, Keramik, Hartpapier, Karton und Rattan sowie unterschiedlichen Formen, Farben und Designs ausgeführt werden. Abhängig von Material und Ausführung ist die erfindungsgemäße Liege, da diese ohne Strom funktioniert, im Innen- sowie Außenbereich einsetzbar.The lounger according to the invention can be made in different materials such as metal, wood, plastic, ceramic, hard paper, cardboard and rattan as well as different shapes, colors and designs. Depending on the material and design, the lounger according to the invention can be used both indoors and outdoors, since it works without electricity.
Die Seitenteile bzw. Rahmen der erfindungsgemäßen Liege sind je nach Material unterschiedlich ausführbar und haben damit auch Auswirkungen auf die Lagerflächen (siehe
Wie in
Die Ausführung der Lager ist abhängig vom Material und kann in Holz als einfaches Auflager bzw. mit Metall-Einlage (z.B. Messing, selbstschmierend), Rollenlager, Gleitlager bzw. Zapfenlager ausgeführt werden. Dies gilt auch für die Position bzw. Ausrichtung dieser Lager (siehe
Auch die Liegeflächen (siehe
Generell gibt es in der Holzausführung zwei Varianten der Selbst-Arretierung. Einerseits die gehauste Ausführung mit seitlichem Knauf (siehe
Daneben sind auch je nach verwendetem Material verschiedene Ausführungen der Rahmenkonstruktion möglich. Einmal aus Brettern wie vorherig dargestellt, oder einfache Rahmen aus Voll-Metall, Rohren (rund, oval, eckig, vierkant, etc.) bzw. Platten, Faltmaterial und Latten möglich.In addition, different versions of the frame construction are possible depending on the material used. Once made of boards as shown above, or simple frames made of solid metal, tubes (round, oval, square, square, etc.) or panels, folding material and slats possible.
Die vorliegende Liege aus Holz ist so konzipiert, dass alle Verbindungen nur mit Verzinkungen hergestellt werden. Dies ist einerseits sehr ökologisch und anderseits für den Herstellungsprozess sehr vorteilhaft. Es können die Verbindungen jedoch auch mit Schrauben hergestellt werden, um einfachere Konstruktionen, die ohne Verzinkungen auskommen, zu verwirklichen. Bei Liegen aus Metall kommen sowieso sinnvollerweise Schraub- bzw. Schweiß-Verbindungen zum Einsatz.The present wooden lounger is designed in such a way that all connections are only made with galvanizing. This is on the one hand very ecological and on the other hand very advantageous for the manufacturing process. However, the connections can also be made with screws in order to realize simpler constructions that do not require galvanization. In any case, screw or welded connections are sensible for metal couches.
Zur Komfortsteigerung ist die Verwendung einer Auflage auf die Liegefläche angebracht, die entweder eine handelsübliche mit Stoff, Leder oder Kork bespannte Schaumstoff- u. o. Latex-matte ist, oder eine Auflage aus gewebter Schafwolle welche mittels eines Klettverschlusses einfach am Rückenteil befestigt werden kann. Natürlich ist auch die Verwendung eines normalen Badetuches möglich. Ebenso sind auch Rollenunterlagen im Nacken- Rücken - oder Knie-Bereich verwendbar.To increase comfort, the use of a support on the lying surface is appropriate, which is either a commercially available foam u. Covered with fabric, leather or cork. o. latex mat, or a layer made of woven sheep's wool which can be easily attached to the back with a Velcro fastener. Of course, you can also use a normal bath towel. Roll pads can also be used in the neck, back or knee area.
Somit bezieht sich die vorliegende Erfindung auf eine Liegevorrichtung zum variablen Verstellen der Position zwischen einer im wesentlichen horizontalen Position und einer ergonomischen sitzenden Position, wie in den
Es gibt generell die Möglichkeit der symmetrischen Selbsthemmung mit Blockierung in beide Bewegungsrichtungen (mit parallel ausgeführten Flanken des Schräg-Schlitzes 71, 261, 271, 281, 291, 301 im Schieber 70, 260, 262, 270, 280, 290, 300, 321, 331, 344, 513, 518) oder der asymmetrischen Selbsthemmung mit Blockierung in nur eine Bewegungsrichtung mit der bevorzugten Blockier-/Gleit-Richtung, welches sich durch unterschiedliche Winkel des Schlitzes 71, 261, 271, 281, 291, 301 im Schieber 70, 260, 262, 270, 280, 290, 300, 321, 331, 344, 513, 518 für Schub-/Druck-Richtung auszeichnet. D.h. die beiden Flanken des Schlitzes sind nicht parallel ausgeführt, sondern weisen unterschiedliche Steigung auf. In Blocker-Richtung (Anlehnen an die Rückenlehne) kommt ein flacher Winkel zur Anwendung, um die Reibung maximal bzw. wie je nach Anwendung erforderlich einzustellen. In der entgegengesetzten Gleit-Richtung (Aufrichten aus der Sitzposition) kommt ein steiler Winkel zur Anwendung, um die Reibung minimal bzw. je nach Anwendung erforderlich einzustellen. Somit entsteht ein asymmetrischer Bewegungsablauf, der in einer Richtung die volle Bremswirkung (Selbsthemmung), und in der entgegengesetzten Richtung maximales Gleiten (sehr geringe oder gar keine Selbsthemmung) ermöglicht.There is generally the possibility of symmetrical self-locking with blocking in both directions of movement (with parallel flanks of the
