Abstract

Most sunbeds or relaxer chairs have a footrest permanently joined to the lateral frame making it difficult to get up or sit down. The footrest (7) of the new design of a relaxer chair can be swiveled into a vertical position around a transversal axis (23). A lever (25) can be used for operating a control mechanism moving the locked seat (5) and backrest (3) into a reclined position. For transport and storage the backrest (3) and the footrest (7) can be folded around horizontal axes (29,41). The rear legs (11) are made of a piece with the armrests (6).

Description

Convertible seat / deck chair

The invention relates to a convertible sitting / lying chair according to the preamble of claim 1.

Seating and reclining furniture, which can be adjusted between a sitting and a reclining position, are well known.

A generic seat / deck chair has become known from FR 635 465 A. This known sitting or reclining furniture also has a foot, which is connected to a horizontal pivot axis with a seat part. Further, an adjusting lever means is provided, which is supported pivotably via a horizontal support axis relative to the frame. The opposite end of the adjusting lever device is also pivotally supported on the foot part via a horizontal support axis.

A convertible sitting and reclining furniture is also known, for example, from EP 0 358 666 B1, which is a Seat part, a backrest and a foot part includes. The backrest is connected by means of a horizontal axis with the seat part and the seat part in turn hinged by means of a horizontal axis with the foot part. For example, the seat or reclining furniture can be folded so that the foot part, the seat part and the back rest are virtually parallel to one another.

This seat and reclining furniture can be set up lounge chairs, so bring in a position in which the

Backrest opposite the backrest backwards upwards and the foot part is aligned from the seat back to the ground down. From this position, it can be adjusted to a lying position, in the foot part, seat part and backrest quasi in a continuous horizontal

Level to come to rest.

Such a convertible sitting and reclining furniture has proven very successful in practice.

Deviating from this, however, there are in principle other seat / deck chairs.

It has become known a seat-deck chair combination, which comprises a one-piece sitting and lying frames, in which therefore the backrest relative to the seat part and the seat part opposite the foot part assumes a fixed predetermined slightly angular orientation to each other. This one-piece support is pivotable about a single horizontal axis relative to a side pedestal. Such couches, also known under the term "health couches" and frequently found in baths, sanatoria, etc., can now be used by weight analysis. be adjusted from a reclining position in which the foot part comes to lie at least approximately horizontally, in a sitting position in which the one-piece seat / recliner combination is pivoted so far until the leading end of the foot rests on the ground.

An advantage of this design lies in the simple design, since the entire seat-lying surface is connected only to a horizontal axis with the supporting frame around which rotates the chair, so no further pivot axes between the backrest and seat part or seat part and footboard are provided. The disadvantage, however, is in such chairs the entry and exit, especially for the elderly.

Because when boarding you either have to make the legs very wide and come from the front coming backwards over the foot part or trying to get in from the side, which is not easy because of the necessary armrest especially when getting out.

The object of the present invention is therefore, starting from the above-described, forming the generic state of the art forming "health lounger" an improved seat and deck chair, which can be adjusted between a sitting and a lying position and the advantages in handling opposite the so-called health bed has.

The object is achieved according to the features specified in claim 1. Advantageous embodiments of the invention are specified in the subclaims. The seat / lounger according to the invention is distinguished from the generic health couch by the fact that the foot part is pivotable about a horizontal axis relative to the seat part. In this case, the construction is such that in the sitting position, the foot part preferably extends vertically downwards, so that it does not interfere with boarding. Since the seat is also preferably located on chair height, you can sit on the inventive seat / reclining furniture as a conventional chair. Subsequently, for example, only by shifting the weight, the seat / back combination, which is pivotally supported in the region of the seat about a horizontal axis relative to the frame, are pivoted to the rear. By means of an adjustment lever construction according to the invention, it is ensured that not only the horizontal axis which is provided at the transition from the seat to the foot part, the foot part is connected to the seat part is raised, but at the same time the foot part is moved from a starting position perpendicular to the floor in the sitting position is raised in an at least approximately horizontal reclining position.

To get off the bed can then be pivoted back again in their sitting position, thereby the lying in the lying position approximately horizontally oriented foot again disappears more or less under the seat part, so at least approximately perpendicular from the horizontal axis lying towards the ground, so that a Getting out is easily possible.

Although there are basically known as "TV armchair", which also by shifting weight and adjustment of the backrest pivoting of the foot in Allow lifted position. However, such sitting / lying furniture has a comparatively complicated adjustment mechanism, often with scissors-type linkage. In contrast, the invention is comparatively simple and only requires a single lever, ie in practice a single lever pair to perform the above-described adjustment. Due to the simple construction principle, the seat / deck chair according to the invention can be used primarily for outdoor purposes, for example in the garden or in bathrooms, but also in commercial areas such as clinics, indoor swimming pools, etc.

In a particularly preferred embodiment, the adjusting lever extends between the frame and the foot part in an orientation which extends almost congruent to the frame part of the seat part. In other words, the frame-side support point, on which the Verstellhebel- device is hinged, provided in the vicinity of the adjustment axis of the seat part relative to the frame part, preferably in an area below the adjustment axis for the seat and / or in an area closer to the foot.

The leading articulation point of the adjusting lever is likewise preferably located in the vicinity of the horizontal pivot axis connecting the foot part to the seat part. In other words, the leading articulation point of the adjusting lever device (which preferably consists of an adjusting lever pair) is articulated at a location on the foot part, which is a relatively small dimensioned and over the horizontal pivot axis between foot and seat part projecting and trained on the footboard Extension represents.

In a particularly preferred embodiment, the leading and returning horizontal pivot axis, on which the pivot lever is articulated, arranged so that the connecting line between this front and rear horizontal axis intersects the connecting line between the seat axis relative to the frame rotatably supporting the horizontal axis and the the foot part extends relative to the seat part pivotable horizontal axis.

In order to prevent too great pivoting from one position to the other, in particular for tall people, a friction or clamping or latching mechanism can be provided, so that the couch is virtually "pre-fixed" in the respective position executed to perform too easy pivoting of the couch alone only by an unintentional shift of weight by the body.

This friction, clamping and / or locking mechanism preferably consists of ribs / depressions which are pressurized with a spring-loaded and are twisted in the circumferential direction and cooperate with a second disc having correspondingly shaped ribs and depressions, so that during pivoting of the seat-lying combination the one locking member relative to the other against a force spring moved apart and are moved towards each other again when reaching a next locking position, in which the couch is then held by the clamping forces generated thereby. This latching and / or clamping device can have a ribbed and / or recess structure which has identically designed ribs and / or depressions or differently shaped ribs and / or depressions, so that different clamping forces are generated in the different lying positions. But this has another positive effect. Because the chair according to the invention without appropriate inhibiting or latching mechanism would make a completely different force required for adjusting for different positions. Because when a person is in the lying position, it requires a greater amount of force to "come up", as in an intermediate position in which the couch is exactly in the balance between tilting forward or backward. Here you needed to further adjustment almost no effort. In the sitting position itself, a slightly greater effort is needed to tilt backwards. Ultimately, this always depends on where the center of gravity is in relation to the axis of rotation of the seat. In order to require in all three positions a similar to the same amount of effort to adjust, now the wells in the lying position, for example, have a flat exit to the front to facilitate the process. In the middle position, the recess could have slightly steeper angles to make adjustment a bit more difficult. In this sense, an optimization can be carried out in the desired sense.

The invention will be explained in more detail with reference to drawings. In detail:

FIG. 11.

FIGS. 1a and 1b show a conventional couch which has become known as a so-called "health bed". It comprises a one-piece seat / lying combination 1 with a backrest 3, a seat part 5 and a foot part 7. This seat / lying combination constitutes a rigid unit, which is usually formed from a surrounding frame in which a fabric-like , slightly pliable and / or padded edition is kept.

The entire frame is held pivotable about a horizontal support shaft 9 relative to a frame 11, wherein the frame 11 usually comprises two mutually offset with side offset frame halves 11 ', between which the sitting / lying combination 1 is arranged. In other words, the entire sitting / lying surface is connected only via this horizontal support shaft 9 with the frame 11 and held over it.

In this case, the frame 11 usually comprises on each side of the sitting / lying combination 1 two feet 13 which, in order to achieve sufficient stability, end offset correspondingly far in the longitudinal direction of the chair offset from one another at the bottom.

In FIG. 1a alone, by shifting the weight, the seat / lying combination can now be pivoted clockwise about the horizontal support shaft 9 from the seat position shown in FIG. 1a, namely until the lying position shown in FIG. 1b has been reached the foot part 7 comes to lie in an approximately horizontal raised orientation.

By reverse weight shift according to the

In FIG. 1 b, the chair can then be pivoted backwards until the leading end 7 'of the foot part 7 rests on the floor 19.

In order to facilitate the weight transfer, an armrest 6 connected to the side frame 11 is also provided.

Since getting in and out of such a "health bed" because of the always above disturbing foot is partly difficult, an improved construction is proposed, which is explained with reference to the figures 2 et seq., Wherein like reference numerals represent comparable parts.

In the embodiment according to FIG. 2 et seq., A seat / lying combination 1 is used from the basic construction, the back part 3 and seat part 5 of which are provided in a predetermined orientation relative to each other, usually representing or being able to represent a fixed or rigid unit. This seat / recliner combination 1 is in turn about a horizontal support shaft 9 relative to the frame 11, so the side frame halves II ¹ , pivotally and is held over it.

However, the foot part 7 is connected to the seat part 5 about a horizontal pivot axis 23 and pivotable relative to the seat part 5.

In order to carry out the pivoting of the foot part 7 in dependence on the sitting or reclining position, an adjusting lever device 25 is also provided, which usually consists of a pair of adjusting levers 25 ', wherein each of the two adjusting lever 25' once on the frame side about a horizontal Supporting axis 27 is pivotable, wherein the opposite end of the respective adjusting lever 25 about a Fußteilseitige further horizontal support axis 29 is pivotable.

As can be seen from the schematic side view according to FIGS. 5 and 6, the adjusting lever action line 31 is in a side view between the two support axes 27 and 29 of the additionally provided adjusting lever 25 arranged and aligned so that this Verstellhebel- line of action 31, the seat axis line of action 33 intersecting between the seat part 5 pivotally supporting horizontal support shaft 9 and the seat part 5 and the foot part 7 pivotally carrying horizontal pivot axis 23 extends.

Furthermore, in the figure 3 also a Verschwenklinie or plane 35 is shown, which in side view by the horizontal pivot axis 23 (about which the foot part 7 relative to the seat part 5 is pivoted) and adjacent thereto arranged Horizontalabstützachse 29, at which the leading end of the Adjusting lever 25 is hinged, runs.

Due to this geometry, the combination of seat and back 5, 3 can now be pivoted clockwise by shifting the weight on the back corresponding to the arrow 15 in Figure 2 (with the relative position between the seat and back not changed, as these preferably in a fixed or rigid alignment with each other, preferably can be formed in one piece). The pivoting movement can be carried out by supporting pushing away on the armrest 6. During the pivoting movement but not only the seat is pivoted about the support shaft 9 in a clockwise direction, but by the superimposed movement or rotational movement of the adjusting lever 25, the support axis 29 so relative to the horizontal pivot axis 23 clockwise pivoted with that when reaching the so-called Liegeposition now the horizontal support axis 29 to the right of the horizontal pivot axis 23 comes to rest. In other words, lent the Verschwenklinie 35 and thus the relative position between the horizontal pivot axis 23 and the horizontal support axis 29 a rotational movement of at least 60 ° and preferably at least 80 °, in particular completed by 90 °, with the result that also the foot part 7 performs a corresponding pivoting movement , For in the sitting position according to FIG. 2, the foot part 7 extends at least approximately perpendicular to the floor 19, whereas in the lying position this foot part 7 is oriented at least approximately horizontally. In this embodiment, therefore, a pivoting movement is realized by almost 90 °, whereby in the sitting position easy entry and exit is made possible.

The desired kinematics is u.a. achieved in that the frame-side support axis 27 comes to lie in a range which is preferably below a horizontal line or plane 37 (Figure 3). Alternatively or additionally, it proves to be advantageous if the frame-side support shaft 27 comes to lie on the side facing the foot part 7 of a vertical line or plane 39, which also extends through the horizontal support shaft 9 (Figure 3).

However, the frame-side support axis 29 can also be supported above the horizontal line 37 on the frame, in particular when the distance between the two support axes 27, 29 and thus the effective length of the pivoting lever 25 is shorter, at least more than 5% and preferably more than 10% shorter than the effective distance between the horizontal support shaft 9 and the horizontal pivot axis 23 with respect to the seat part. 5 Finally, a favorable kinematics can also be realized if the distance between the supporting shaft 9 fixed on the frame side and the support axis 29 lying adjacent thereto is less than 25%, in particular less than 15%, 10% and in particular less than 8% or even 6% and / or preferably more than 2%, in particular more than 4%, 6%, 8% or 10% of the distance of the support shaft 9 relative to the bottom 19. Same preferred ranges also apply to the distance between the horizontal pivot axis 23 and the support axis 29th

In this arrangement, also proves to be advantageous in aesthetic terms, that the at least one and preferably two provided with lateral offset pivot lever pivot 25 'virtually "hidden" behind the frame portion of the seat part 5, so hardly appear, especially if the respective adjusting lever 25 'is arranged directly on the inner side of the outer frame section of the seat part 5.

For pivoting itself, a person sitting on the seat or deck chair can in turn easily rest on the armrests 6, which are designed as extended sections of the side frame halves 11 '.

With reference to FIG. 7, in a single drawing corresponding to the schematic illustration according to FIGS. 5 and 6, the seat / deck chair according to the invention is shown in its initial position, in its final lying position and in an intermediate adjustment position during the adjustment process, around the adjusting mechanism better understandable. Finally, in the drawings, in particular in Figures 2 and 3, also a horizontal stop axis 65 located between the two frame halves 11 'extends. This horizontal axis 65 serves as a stop axis for the backrest 3. This limits the maximum adjustment movement in the lying position. The stop axis 65 is arranged at such a height on the frame, that in this the lying position limiting end position, the foot part 7 comes to rest horizontally or preferably at least approximately horizontally.

In principle, the backrest 3 can also be pivoted relative to the seat part 5 by a separate mechanism, for which purpose a backrest pivot axis 41 is indicated in the drawings according to FIGS. 2 and 3. In this case, a corresponding locking mechanism would also have to be provided. It is also possible in this context that the backrest 3 strikes in the sense of a maximum opening angle relative to the seat part 5 on a rear stop and not further towards the seat part 5 can be opened, but forward to achieve a favorable storage position on the seat part 5 can be pivoted or then transferred.

Preferably, the seat / deck chair described is not daily collapsible camping furniture. However, this chair is preferably collapsible and stowable, for example, in the fall. For this purpose, as mentioned, the back rest 3 can be folded around the aforementioned axis 41 on the seat surface to the front. For example, by two screws for the axis 27 are solved with a tool 127 (in particular a wrench), the chair be further merged, as can be seen in Figure 4 in the Seitendarsteliung, in which position then the foot part 7 is parallel to the seat part 5. Since the leading foot or that leading pair of feet can be pivoted about an overhead axis 101 to the rear, the chair, as shown in the side view of Figure 4, be merged, where he, for example, only a height of about 30 cm and a length of about 120 cm.

Although the described adjustment mechanism works without problems, tilting may possibly be effected too easily in the case of tall persons, namely possibly due to an unintentional shifting of the weight, possibly resulting in an unsafe feeling.

Therefore, a gripping and / or latching device 51 may additionally be provided, which is preferably arranged between two veschwenkbaren parts relative to each other. In that regard, reference is also made to the following drawings according to the figures 8a to 12, to which reference is made below.

In particular, the area with respect to the support axle 9 or the horizontal support axle 27 is suitable for this purpose.

For example, it would be possible to provide a friction, clamping or latching device between the inside of the frame half II ^1, for example, of the base 13 bearing the support shaft 9 and the outwardly facing adjacent side of the end of the adjustment element 25 the sitting / lying area counteracts.

For this purpose, a latching device is preferably proposed, which comprises, for example, a plate-shaped or dividing-shaped clamping or latching half 53, which is provided on the inside of the respective outer frame half, for example in the region of the support axis 27, ie is penetrated by the support axis 27. In this case, ribs or webs 57 projecting in the circumferential direction and projecting in the axial direction are formed, between which depressions, notches or grooves 59 are provided, wherein beveled slopes 61 are formed between the ribs and depressions.

At the adjusting lever 25, a further engagement projection 65 (or engagement recess or notch) can now be provided before and after attachment via the horizontal support axis 27, as is indicated by FIGS. 8a to 10b.

Finally, the plate device is pressurized by a force spring accumulator 67 according to the arrow 68 in FIG. 11, which can be supported by a rear support plate 69. This rearward support plate 69 is held by a sleeve 70, which may be penetrated by the axle 27.

If the couch is to be changed in its alignment position, the entire seat lying surface is pivoted as described, when the weight is displaced, whereby the two adjustment levers 25 also perform a corresponding rotational movement about the adjustment-side horizontal support axis 27. In this adjustment, then, for example, the am Adjustment lever 25 formed projection 59 (or rib 59, etc.) from the recess 59 (formed on the plate-shaped clamping or latching half 53), which is rotationally connected to the frame 11. The lifting out of the projection 75 from the recess 59 takes place in each case via the obliquely mutually inclined surfaces 61, as shown in the transition from Figure 8a to Figure 9a. As a result, the adjusting lever 25 is axially displaced at its rear attachment region on the horizontal support axis 27 against the biasing action of the force accumulator 67 against the arrow 68 in FIG. 9a. Upon further adjustment of the engagement projection 65 is then pressed in reaching a next recess, notch, groove 59, etc. back into this depression, through the force spring accumulator 67, whereby a next detent position of the seat-lying surface is achieved. In this position, in turn, the reclining seat position in the respective position is stabilized according to the spring force.

The magnitude of weight shifting forces that must be applied to effect a positional change ultimately depends on the force storage device 67, i. the clamping force generated thereby as well as the size and height of the engagement projections 67 and the ribs or webs 55 and alignment of the respective slope surface 61st

It is shown with reference to FIGS. 8a to 10a that the ribs and webs on the one hand and the indentations, notches, grooves on the other as well as their height and their inclination surfaces 61 can be dimensioned the same. To ensure in the different positions that the force required to adjust the chair is about the same, it is under It may be necessary to provide the depressions or the height of the notches and the inclined surfaces with different angles, thereby effecting the desired adjustment in order to equalize the forces required to move the chair.

However, as also shown with reference to FIGS. 11 and 12, the angles α, β or Y can be chosen differently with respect to the different inclination surfaces 61 and also the width 57a of the ribs or webs 57, so that due to the different "extension angles" formed in this way give different resistances when reaching or leaving different seat reclining positions. In other words, to leave a certain selected position then a different force required to perform the adjustment.

Finally, however, even more locking and / or adjusting, for example in the manner of a parking brake possible, for example, to secure a chair in a middle position so that an unintentional adjustment is no longer possible.
