Description

The The invention relates to a sitting / lying furniture according to the The preamble of claim 1 with at least one fixed support part, wherein on the support part at least one device for Adjusting a support member relative to the support member is arranged, and the device at least one pivoting element and has at least one retaining element, wherein the pivoting element the adjustable support part on the support part movable stores and the retaining element, the support member in a Nutzstellung fixed.

Such an arrangement is for example from the DE 39 28 005 A1 known. In this document, a device is disclosed which supports a support member by means of several pivotal lever designed as pivoting elements on the support member pivotally. When pivoting the support member not only the inclination angle of the support member relative to the support member is changed, but also the position of the support member to the support member. Here, the pivot lever both rotate about a pivot point near its attachment point on the support member and about a pivot point near its attachment point on the support member to avoid contact of the support members with a located behind the support member wall. The fixation of the support member in a use position is realized by means of a length-adjustable support lever. However, it has proved to be disadvantageous that the corresponding device for the pivotable mounting of a support member relative to a support member is laterally quite unstable, since large leverage forces act on the pivot points of the support lever. For lateral stabilization of the pivotal connection of the support member to the support member, the pivot lever and the rotatable connection to the brackets of the pivot lever must be made particularly solid. The required pivot lever are on the one hand very heavy and on the other hand correspondingly expensive.

It Therefore, the object of the present invention is a sitting / lying furniture to provide in which the said disadvantages of the prior art be avoided. In particular, a sitting / lying furniture too create, in which by means of a device a cost-effective and stable alternative is created, a support member movable to store and to fix in at least one position of use.

The Task is based on a sitting / lying furniture according to the The preamble of claim 1 in conjunction with the characterizing features solved. Advantageous developments of the invention are specified in the dependent claims.

According to the invention provided that the pivoting element designed as a rotary hinge is to the support member on the support member to a fixed Store fulcrum.

Advantageous Here is a possible arrangement of the rotary hinge at the free end of the support part facing region of Support part. This would be an arrangement of the legs the rotary hinge both above and below an axis the fixed pivot point on the support part and on the support part conceivable. It is particularly advantageous if the rotary hinge designed with a pivot pin, which is a special stable, rotatable connection between the support part and the carrier part manufactures. An arrangement of the support part on the seat / reclining furniture is both as a lateral Lehnteil, as well as head / back part conceivable. Likewise it can in the sitting / lying furniture also around a bed, sofa, couch or the like. The carrier part can by the Frame made of sitting / lying furniture. Also can the carrier part as an additional part of the frame even be attached, it even solvable to the frame can be attached.

Further It is conceivable that multiple hinges with fixed pivot points form a uniform axis of rotation, in particular two hinges rotatably support the support part on the support part. By two hinges in the largest possible distance mounted on each other on the support member and the support member are, a high lateral stability for the rotatable stored connection reached. Also, the arrangement of an over the width of the support member continuous rotary hinge in the form of a piano strap for rotatably supporting the support member on the support part is conceivable. For arranging the rotary hinge to the support member and the support member would be It is also conceivable that the legs of the rotary hinge, by means of for example, a bonding agent such as screws, Rivets or the like, on the support member and / or support member are fastened, by the (fabric) cover of the support member and / or the support member at least partially covered and so that they are partially invisible. On the other hand, the legs could be designed as ornamental thighs and by means of a chromed or a dull stainless steel surface or similar Ornamental design uncovered on the support part and / or be mounted on the support part.

Of Furthermore, it is provided according to the invention that the holding element made adjustable in length is and both the support member and the support part is rotatably arranged. Advantageously, the retaining element this close to its connection points both to the support part as well as the support member provided with hinges.

In a further alternative of the invention, the support member can be fixed in at least two use positions by means of the holding element. Advantageously, the different utilizations can be achieved realize a direct manual action on the support member without direct contact with the holding element. By raising or lowering the free end of the support member in this case the supported by the support member Nutzstellungen for the support member can be adjusted.

Also It is conceivable that a position of the support member relative to the support member in the use position has an angle of 0 ° ≤ α ≤ 45 °. By securing the support member in a position larger the maximum use position can be achieved by means of an unlocking of the retaining element the transfer of the support part in one Resting position can be achieved, wherein the support member relative to the support part has an angle of almost α = 0 °.

According to one Another variant of the invention is the retaining element as a locking rail executed and almost horizontally centered below a rotation axis mounted on the support part and on the support part. By the configuration of the retaining element as a latching rail is a stepwise Positioning of the support part in a use position possible. Advantageously, this is done by means of two with large Distance from each other arranged hinges the side stability the movable mounting of the support member on the support part supports the supporting part with the locking rail to fix in at least two uses. Likewise optionally also a plurality of retaining element or locking rails for fixing be provided of the support member on the support member, whereby the stability can be further increased.

Farther can be provided that a first contact surface and a second contact surface executed at least partially flat are. Due to the flat design of the first and second Contact surface can in the rest position of the support part through a large concern of the first contact surface at the second contact surface a nearly parallel storage ensures the support member on the support member become.

Further it is conceivable that the first contact surface and / or the second contact surface with at least one opening is designed. The opening is at least partially Recording of the holding element executed. As advantageous has been found, if the holding element itself at least partially disposed within the opening. in this connection It is conceivable that a first mounting position of the holding element and / or a second mounting location of the holding element are located within an opening. By arranging at least one mounting place of the holding element within an opening can be ensured that the holding element, the support member by means of a simple linear mechanism both in the use position and in the Rest position can fix. It has proved particularly advantageous in the rest position of the support part relative to the support part, the holding member at least partially received within the opening is to be a large-scale concern of the first To allow contact surface on the second contact surface.

By Another measure can be provided that a distance to the fulcrum (of the support member) from a first mounting place the retaining element on the first contact surface of the support part is shorter than a distance from the fulcrum (of the support member) to a second mounting location of the holding element on the second contact surface of the support part. By this arrangement of the holding element to the support member and the support member is the power which acts on the holding element in the region of the second mounting place, reduced. This allows a stable support of Support member can be realized in a Nutzstellung.

In Another possible embodiment the first contact surface of the support member a receptacle have, in which the support member at least partially storable is. It is advantageous if the support member at least with a portion of the second abutment surface of the free end the support member in the rest position within the recording is included. This allows the lateral freedom of movement of Support part are restricted and thereby the lateral stability of the support member can be increased in the rest position.

Of Furthermore, it can be provided inventive that the device for the support member exactly two hinges and a laterally centered, arranged between the rotary hinges locking rail having. It has been found that by means of such Device a particularly high stability in the mobile Support of the support part on the support part, at a low installation costs can be achieved.

In 1 is a first embodiment of the sitting / lying furniture according to the invention 1 shown in a use position. In this embodiment, a support member 40 by means of a device 30 pivotable on a support part 20 attached. The device 30 contains a pivoting element 31 and a holding element 32 , The holding element 32 is as extendable latching rail 32 executed, both on the support part 20 as well as on the support part 40 is rotatably mounted and mounted. The pivoting element 31 is as a hinge 31 executed and holds the support part 40 around a fixed pivot 33 rotatably mounted on the support part 20 , The rotary hinge 31 has two legs 31a . 31b the at a (rotary) bolt around a pivot point 33 are rotatably arranged. The thigh 31a of the rotary hinge 31 is at the top 24 the free end of the carrier part 20 flush with a first contact surface 21 by means not shown connecting means (such as screws, rivets, bolts or the like) mounted. The second leg 31b of the rotary hinge 31 is also above the support part 40 on a second contact surface 41 by means not shown connecting means on the support member 40 assembled. Due to the freely accessible arrangement of the upwardly directed legs 31a . 31b is a simple mounting of the legs 31a . 31b , by means of z. B. screws as connecting means, both on the support part 20 as well as on the support part 40 possible. In principle, an arrangement of at least one leg would be 31a . 31b of the rotary hinge 31 in the area of the first contact surface 21 just as conceivable. Also both thighs can 31a . 31b be directed downward so that they appear barely visible in appearance. When arranging the rotary hinge 31 in 1 the angle between the legs behaves 31a . 31b above the fixed pivot 33 opposite proportional to the angle between the support part 40 and the carrier part 20 starting from the fixed pivot 33 ,

The support part 40 is in the area of its contact surface 41 with an opening 42 designed in which the locking rail 32 at a second assembly site 32b is rotatably mounted. Also is the carrier part 20 at the first contact surface 21 with an opening 22 designed, on which the locking rail 32 at a first assembly site 32a is rotatably mounted. The locking rail 32 is designed with various detents and by lifting the surface 43 abgewanden free end of the support member 40 operable. So can in a like in 5 represented angle α the support member 40 on various positions of 0 ° ≤ α ≤ 45 ° in a use position by means of the locking rail 32 be arrested. At an extension of the locking rail 32 near the maximum use position of the support part 40 , unlocks the latching rail, causing the support member 40 - Without further handling - easily and simply traceable to the rest position.

As in 1 can be seen, is the removal of the first assembly place 32a to the fulcrum 33 shorter than the distance of the second mounting place 32b of the holding element 32 to the fulcrum 33 , Both in the area of the first assembly place 32a as well as in the area of the second assembly station 32b is the retaining element 32 rotatably mounted.

The opening 22 . 42 takes the locking rail 32 in a parallel position of the first contact surface 21 the carrier part 20 and the second contact surface 41 of the support part 40 almost completely on. This becomes a concern of the first contact surface 21 at the second contact surface 42 allows.

Like from the 1 can be seen, the support member protrudes 40 with its upper end clearly above the top 24 the carrier part 20 out, while still - due to the special arrangement of the rotary hinge 31 with the fulcrum 33 - it is avoided that the support part 40 in the use position to a behind the support part 20 arranged wall can reach. Consequently, the freedom of movement of the support member 40 on the support part 20 unrestricted, so the sitting / reclining furniture 1 with the carrier part 20 with one of the first contact surface 21 facing away from a wall can stand. It is also conceivable that the rotary hinge 31 so on the sitting / lying furniture 1 is fastened that both thighs 31a . 31b are directed downwards. In this case, the rotary hinge 31 barely visible on the sitting / lying furniture 1 arranged. Thus, on a possible cover or veneering of the rotary hinge 31 be waived.

2 shows a partial view of another embodiment of the sitting / lying furniture according to the invention 1 in a rest position. The Trä gerteil 20 and the support part 40 are arranged almost parallel to each other here. On the top 24 the carrier part 20 at the edge of the support part 40 are two hinges 31 with her thighs 31a assembled. The fixed pivot points 33 the hinges 31 make up at the level of the top 24 the carrier part 20 and the support part 40 a fixed axis of rotation 33 ' to the the supporting part 40 for securing in a use position rotatable on the support part 20 is stored. In the area of the first and second contact surface 21 . 41 are the support part 40 and the carrier part 20 with the openings 22 . 42 designed in which the retaining elements 32 are included. The hinges 31 are at a great distance from each other on the support part 40 and on the carrier part 20 mounted to the greatest possible lateral stability of the support part 40 to ensure in a position of use. Of course, the arrangement of other hinges 31 along the axis of rotation 33 ' , or the arrangement of one along the edge portion of the surface 24 mounted through, as a piano band 31 executed rotary hinge 31 conceivable.

In 3 and 4 is the embodiment according to 1 of the sitting / lying furniture according to the invention 1 with a dynamic pivoting view of the support part 40 over the fixed pivot axis 33 ' shown. The angle α gives a position 34 again, the one use position of the support part 40 relative to the carrier part 20 can take. Here, the use position can assume an angle of 0 ° ≤ α ≤ 45 °. Number and angle of Nutzstellungen is here by the extensibility and the lockability of the locking rail 32 executed holding element 32 certainly. Due to the arrangement of the pivoting element 31 would be without limitation by the holding element 32 firmly attached to both the carrier part 20 as well as on the support part 40 is mounted, also a position of the support member 40 relative to the carrier part 20 reachable by a maximum of α = 90 °. The contact surfaces 21 . 41 are just designed and allow a parallel concern of the support member 40 on the support part 20 ,

In 4 is the rotation axis 33 ' passing through the fixed pivot points 33 unrepresented hinges 31 is formed, drawn around the the support part 40 relative to the carrier part 20 is pivotable.

In 5 and 6 is at a third embodiment of the invention sitting / lying furniture 1 a recording 23 arranged, starting from the axis of rotation 33 ' the support part 40 in some areas. The rotation axis 33 runs almost vertically in the middle along the top 24 the carrier part 20 , In the rest position, there is the second contact surface 41 of the support part 40 mostly within the recording 23 the carrier part 20 ,

At the in 7 and 8th illustrated embodiment of the sitting / lying furniture according to the invention 1 is the support part 40 by means of a pivoting element 31 flush with the top 24 the carrier part 20 arranged. The top 24 the carrier part 20 and the top 43 of the support part 40 form a plane. Here are the thighs 31a . 31b as a rotary hinge 31 executed pivoting element 31 on the tops 24 . 43 both of the support part 20 as well as the support part 40 assembled. An attachment of the thighs 31a . 31b at the first contact surface of the carrier part 20 and or the second contact surface 41 of the support part 40 is also conceivable.
