Abstract

The seating or reclining furniture (1) comprises a fixed carrier part (20). A unit (30) is arranged relative to the carrier part for adjusting a supporting part (40) at the carrier part. The unit comprises a swiveling element (31) and a retaining element (32). The swiveling element is designed as a rotary hinge to store the supporting part at the carrier part around a fixed pivot point (33).

Description

The invention relates to a seat / reclining furniture according to 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 is arranged relative to the support member, and the device comprises at least one pivot member and at least one retaining element, wherein the pivotal element movably supports the adjustable support part on the support part and the retaining element fixes the support part in a use position.

Such an arrangement is for example from the DE 39 28 005 A1 known. In this document, a device is disclosed which Supports supporting part 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 is therefore the object of the present invention to provide a sitting / lying furniture, in which the mentioned disadvantages of the prior art are avoided. In particular, to provide a sitting / reclining furniture, in which by means of a device, a cost-effective and stable alternative is created to store a support member movably and to fix in at least one use position.

The object is achieved on the basis of a seat / reclining furniture according to the preamble of claim 1 in conjunction with the characterizing features. Advantageous developments of the invention are specified in the dependent claims.

According to the invention it is provided that the pivoting element is designed as a rotary hinge to support the support member on the support member about a fixed pivot point.

An advantage here is a possible arrangement of the rotary hinge at the free end of the support part facing portion of the support member. Here, an arrangement of the legs of the rotary hinge both above and below an axis of the fixed pivot point on the support member and the support member would be conceivable. It is particularly advantageous if the rotary hinge is designed with a pivot pin, which produces a particularly stable, rotatable connection between the support member and the support member. An arrangement of the support member sitting / lying furniture is conceivable both as a lateral Lehnteil, and as a head / back part. Likewise, the sitting / lying furniture can also be a bed, sofa, couch or the like. The support part can be formed by the frame of the seat / reclining furniture. Also, the support member may be attached as an additional part of the frame itself, and it may even be releasably secured to the frame.

Furthermore, it is conceivable that a plurality of rotary hinges with fixed pivot points form a uniform axis of rotation, wherein in particular two rotary hinges rotatably support the supporting part on the carrier part. By two hinges which are mounted at the greatest possible distance from each other on the support member and the support member, a high lateral stability is achieved for the rotatably mounted connection. The arrangement of a continuous over the width of the support member rotary hinge in the form of a piano strap for rotatably supporting the support member on the support member is conceivable. For the arrangement of the rotary hinge on the support member and the support member, it would also be conceivable that the legs of the rotary hinge, which can be fastened by means of, for example, a connecting means, such as screws, rivets or the like, on the support member and / or support member through the (fabric ) Reference of the support member and / or the support member are at least partially covered and thus partially invisible. On the other hand, the legs could be designed as ornamental thighs and be uncovered by means of a chromium-plated or a matt stainless steel surface or a similar ornamental design on the support member and / or on the support member.

Furthermore, the invention provides that the holding element is designed to be adjustable in length and is rotatably arranged both on the support member and on the support member. Advantageously, the holding element is provided for this purpose near its connection points both to the support member and the support member 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 use positions can be realized by a direct manual action on the support member without direct contact with the support member. 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.

It is also 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 greater than the maximum use position, the transfer of the support member into a rest position can be achieved by unlocking the support member, wherein the support member has an angle of almost α = 0 ° relative to the support member.

According to a further variant of the invention, the holding element is designed as a latching rail and mounted almost horizontally in the middle below an axis of rotation on the support member and the support member. Due to the configuration of the retaining element as a latching rail, a stepwise positioning of the support member in a use position is possible. Advantageously, the lateral stability of the movable support of the support member is supported on the support member by means of two widely spaced rotary hinges to fix the support member with the locking rail in at least two use positions. Likewise, optionally, a plurality of holding elements or latching rails for fixing the support member may be provided on the support member, whereby the stability can be further increased.

Furthermore, it can be provided that a first contact surface and a second contact surface are at least partially flat. Due to the planar design of the first and second bearing surface can be ensured in the rest position of the support member by a large-scale abutment of the first contact surface on the second contact surface a nearly parallel mounting of the support member on the support member.

Furthermore, it is conceivable that the first contact surface and / or the second contact surface is configured with at least one opening. The opening is designed at least for partially receiving the retaining element. It has proven to be advantageous if the holding element itself is at least partially disposed within the opening. In this case, it is conceivable for a first mounting location of the retaining element and / or a second mounting location of the retaining element to be located within an opening. By arranging at least one mounting place of the holding element within an opening, it can be ensured that the holding element can fix the supporting part by means of a simple linear mechanism both in the use position and in the rest position. It has proven to be particularly advantageous that in the rest position of the support part relative to the support part, the retaining element is at least partially received within the opening to allow a large-area concerns the first contact surface on the second contact surface.

By a further measure it can be provided that a distance to the fulcrum (of the support part) from a first mounting location of the holding element on the first abutment surface of the carrier part is shorter than a distance from the fulcrum (of the support part) to a second mounting location of the holding element on the second Contact surface of the support part. By this arrangement of the retaining element to the support member and the support member is the force acting on the retaining element in the region of second mounting place acts, reduced. In this way, a stable support of the support member can be realized in a Nutzstellung.

In a further possible embodiment, the first contact surface of the support part may have a receptacle in which the support part is at least partially storable. It is advantageous here if the support member is received at least with a portion of the second bearing surface of the free end of the support member in the rest position within the recording. As a result, the lateral freedom of movement of the support member can be limited, thereby increasing the lateral stability of the support member in the rest position.

Furthermore, it can be provided inventive that the device for the support member has exactly two hinges and a laterally centered, arranged between the rotary hinges locking rail. It has been found that by means of such a device, a particularly high stability in the movable mounting of the support member on the support member, can be achieved with a low installation cost.

In FIG. 1 a first embodiment of the sitting / lying furniture 1 according to the invention is shown in a use position. In this embodiment, a support member 40 is pivotally attached by means of a device 30 to a support member 20. The device 30 in this case contains a pivoting element 31 and a holding element 32. The holding element 32 is designed as an extendable latching rail 32 which is rotatably mounted and mounted both on the support member 20 and on the support member 40. The pivoting element 31 is designed as a rotary hinge 31 and holds the support member 40 rotatably supported about a fixed pivot 33 on the support member 20. The hinge 31 itself has two legs 31a, 31b which are rotatably mounted on a (rotary) pin about a pivot 33 , The leg 31a of the rotary hinge 31 is flush with the top 24 of the free end of the support member 20 with a first Bearing 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 mounted above the support member 40 on a second abutment surface 41 by means not shown connecting means on the support member 40. Due to the freely accessible arrangement of the upwardly directed legs 31a, 31b, a simple mounting of the legs 31a, 31b, by means of z. As screws as connecting means, both on the support member 20 and on the support member 40 is possible. In principle, an arrangement of at least one leg 31a, 31b of the rotary hinge 31 in the region of the first contact surface 21 would also be conceivable. Also, both legs 31a, 31b may be directed downwards, so that they appear barely visible in appearance. In the arrangement of the rotary hinge 31 in FIG. 1 The angle between the legs 31a, 31b above the fixed pivot point 33 is opposite to the angle between the support part 40 and the support part 20, starting from the fixed pivot point 33.

The support member 40 is configured in the region of its contact surface 41 with an opening 42 in which the latching rail 32 is rotatably mounted on a second mounting position 32b. Likewise, the support part 20 is configured on the first abutment surface 21 with an opening 22 on which the detent rail 32 is rotatably mounted on a first mounting location 32a. The latching rail 32 is configured with various detent points and by means of lifting of the surface 43 abgegewanden free end of the support member 40 operable. So can in a like in FIG. 5 represented angle α, the support member 40 are locked at various positions of 0 ° ≤ α ≤ 45 ° in a use position by means of the locking rail 32. Upon extension of the locking rail 32 near the maximum use position of the support member 40, unlocks the locking rail, whereby the support member 40 - without further handling - easily and easily traceable to the rest position.

As in FIG. 1 can be seen, the distance of the first mounting place 32a to the fulcrum 33 is shorter than the distance of the second mounting position 32b of the holding member 32 to the fulcrum 33. Both in the region of the first mounting place 32a and in the region of the second mounting place 32b, the holding member 32 is rotatably mounted ,

The opening 22, 42 takes the locking rail 32 at a parallel position of the first contact surface 21 of the support member 20 and the second bearing surface 41 of the support member 40 almost completely. As a result, a concern of the first contact surface 21 on the second contact surface 42 is made possible.

Like from the FIG. 1 can be seen, protrudes the support member 40 with its upper end clearly above the top 24 of the support member 20, while still - due to the special arrangement of the hinge hinge 31 with the fulcrum 33 - is avoided that the support member 40 in the use position to a rear can reach the support member 20 arranged wall. Consequently, the freedom of movement of the support member 40 on the support member 20 is unrestricted, so that the sitting / lying furniture 1 with the support member 20 may be with one of the first contact surface 21 opposite side to a wall. It is also conceivable that the rotary hinge 31 is attached to the sitting / lying furniture 1, that both legs 31a, 31b are directed downward. In this case, the rotary hinge 31 is arranged barely visible on the sitting / lying furniture 1. Thus, a possible cover or veneering of the rotary hinge 31 can be dispensed with.

FIG. 2 shows a partial view of another embodiment of the invention seat / reclining furniture 1 in a rest position. The support member 20 and the support member 40 are in this case arranged almost parallel to each other. On the top 24 of the support member 20 edge of the support member 40 has two hinges 31 are mounted with their legs 31 a. The fixed pivot points 33 of the hinges 31 form at the level of the top 24 of the support member 20 and the Support member 40 has a fixed axis of rotation 33 ', around which the support member 40 is rotatably mounted for securing in a use position on the support member 20. In the region of the first and second bearing surface 21, 41, the support member 40 and the support member 20 are configured with the openings 22, 42, in which the holding elements 32 are received. The hinges 31 are mounted at a great distance from each other on the support member 40 and the support member 20 to ensure the greatest possible lateral stability of the support member 40 in a use position. Of course, the arrangement of further rotary hinges 31 along the axis of rotation 33 ', or the arrangement of a along the edge portion of the surface 24 mounted continuous, designed as a piano hinge 31 rotary hinge 31 is conceivable.

In FIG. 3 and FIG. 4 is the embodiment according to FIG. 1 of the seat / recliner 1 according to the invention with a dynamic pivotal view of the support member 40 on the fixed pivot axis 33 'shown. The angle α represents a position 34, which can occupy a useful position of the support member 40 relative to the support member 20. Here, the use position can assume an angle of 0 ° ≤ α ≤ 45 °. The number and angle of the use positions is determined here by the extensibility and the lockability of the holding element 32 designed as a latching rail 32. Due to the arrangement of the pivot member 31 would be without limitation by the support member 32 which is fixedly mounted on both the support member 20 and the support member 40, also a position of the support member 40 relative to the support member 20 of a maximum α = 90 ° achievable. The contact surfaces 21, 41 are planar and allow a parallel abutment of the support member 40 on the support member 20th

In FIG. 4 is the axis of rotation 33 ', which is formed by the fixed pivot points 33 of unillustrated rotary hinges 31, located around which the support member 40 is pivotable relative to the support member 20.

In FIG. 5 and FIG. 6 is on a third embodiment of the seat / reclining furniture 1 according to the invention a receptacle 23 is arranged, which receives starting from the axis of rotation 33 ', the support member 40 partially. The axis of rotation 33 extends almost vertically in the middle along the upper side 24 of the carrier part 20. In the rest position, the second contact surface 41 of the support member 40 is largely within the receptacle 23 of the support member 20th

At the in FIG. 7 and FIG. 8 illustrated embodiment of the sitting / lying furniture 1 according to the invention, the support member 40 is arranged by means of a pivot member 31 flush with the top 24 of the support member 20. The top 24 of the support member 20 and the top 43 of the support member 40 form a plane. Here, the legs 31 a, 31 b of the rotary hinge 31 designed as a pivot member 31 on the upper sides 24, 43 of both the support member 20 and the support member 40 is mounted. An attachment of the legs 31a, 31b on the first contact surface of the support member 20 and / or the second contact surface 41 of the support member 40 is also conceivable.
