Description

AT 392 888 B

The invention relates to a convertible into a piece of furniture with a furniture frame on which a backrest part is pivotally mounted by means of at least one handlebar, the backrest part being articulated to a seat part which is guided by means of rollers on a guide provided on the furniture frame, wherein the guide extends obliquely upwards at least on its area facing the front, and a bedding drawer is optionally provided below the seat part.

In known seating furniture, which can be converted into a recliner, the seat part is connected to the backrest part in various ways, u. Mostly in such a way that when the seat is pulled forward the backrest can also be brought into a lying position, or that with such handling the backrest must be brought into the position corresponding to the lying position by hand, which in all cases requires a greater amount of work.

In order to improve the handling of this piece of furniture, it has already been proposed that the backrest part is articulated to the seat part by means of two lateral pairs of links, which are articulated on the one hand at the upper end of the frame and on the other hand on the retractable and pushable seat part, and that the backrest part at Pulling the seat part forward behind it is folded down (CH-PS 632 401).

The object of the invention is to further improve this seating of the type mentioned.

This is achieved in accordance with the invention in a piece of seating furniture of the type mentioned at the outset in that at least one freely hanging arm is pivotally mounted on the backrest part or on arms firmly connected to it in a manner known per se, which arm is freely downward in the region of the arm hanging end a bracket, e.g. B. in the form of a recess, which can be supported for adjusting the seating from the lying position to the sitting position on a fixed to the furniture frame in a known manner bearing, in particular a stop. In this way, a lever joint for moving the seating furniture from the lying position into the sitting position is formed. It further simplifies the construction of the furniture according to the invention and reduces the effort required for converting the reclining furniture from the lying position to the sitting position, since the lever joint formed with the simplest means briefly forms a double-armed lever, by means of which the initial uprighting of the backrest can be adjusted Weight of the seat part can be used.

In the furniture known from DE-AS 1 070 799, there is no obliquely upward guide; this is completely flat. In the furniture known from this document and also from DE-AS 1 039 727 are already attached to the one part (backrest part) of a convertible piece of furniture, freely hanging down, pivoted arms, which with recesses arranged at one end with stops , which belong to the other furniture part (seat part), come into engagement and thereby establish a connection, known. However, these stops are not — as required by the present invention — firmly attached to the furniture frame. Rather, they are movable with respect to the furniture frame.

From DE-AS 2 816 191 it is known to bring a furniture frame, on which a stop is firmly attached, into engagement with the seat frame of the furniture via a recess. However, this last-mentioned embodiment has neither an obliquely upward guide, nor a freely hanging arm.

In order to reduce the effort required for converting the seating furniture from the lying position into the sitting position by far »1, it is advantageous according to a further embodiment of the invention that the arm of the backrest part hanging freely downward in the area between the articulated connection between the backrest part and the seat part and the articulation of the handlebar on the backrest part or on the arm firmly connected to it, in the vicinity of the articulated connection of the backrest part and the seat part. In this way, favorable leverage ratios are achieved, which require little effort to convert the seating furniture.

According to a further embodiment, it can be provided that the stop firmly attached to the furniture frame is arranged on the side of the arm of the backrest part which hangs freely downwards and faces the front of the seat part. However, the stop fixed to the furniture frame can also be arranged laterally at a distance in the reclining position of the seat be arranged above the recess of the arm hanging down. This results in advantages in the handling and / or manufacture of the furniture according to the invention.

It is expedient that one arm is provided on each side of the backrest part, which projects into the respective space between the seat part and the furniture frame, with a stop fixed to the furniture frame being provided on the two opposite inner sides of the furniture frame.

The invention is described below with reference to the drawing, in which an embodiment of the subject matter of the invention is shown.

1 shows a side view of the seating furniture according to the invention in the sitting position, the front frame part having been omitted for the purpose of clarification of the parts, FIG. 2 shows a side view of this seating furniture according to the invention in the lying position, the front frame part again being omitted, FIG. 3 shows a section along Line (III-III) in Fig. 1, Fig. 4 shows a section along line (IV-IV) in Fig. 2, and Fig. 5 shows a variant with respect to the arm.

The seating furniture shown, which can be converted into reclining furniture, comprises a furniture frame (1) on which a backrest part (2) can be pivoted and on which a seat part (3) is slidably mounted. The backrest part (2) is provided with two side arms (4) which are firmly connected to the backrest part (2) at their upper end by means of screws (5) (Fig. 3), and on the other hand with pins at their lower end (6) are articulated on the seat part (3). On each side arm (4) of the backrest part (2) is in the range of its -2-

AT 392 888 B

Attachment to the backrest part (2) by means of a pin (17) articulates a link (7) which is articulated at its other end with a pin (8) on the frame (1).

The seat part (3) is provided in the region of its end facing the backrest part (2) with downward projections (9), on which sliding rollers (10) are rotatably mounted. The castors (10) are guided in guides (11) which are attached to the inside of the furniture frame (1). The guides (11) run essentially horizontally, the end facing the front side of the seating furniture being directed obliquely upwards. The guides (11) are, for. B. manufactured by means of isosceles angle profiles

Dot seat part (3) is further provided in the region of its front end with downwardly directed frame parts (12) on which rollers (13) are rotatably mounted, by means of which the seat part (3) can be moved on the floor.

On the arms (4) with which the backrest part (2) is articulated to the seat part (3), one arm (14) is freely pivoted. The pin (14 ') with which the arm (14) is articulated on the arm (4) is closer to the pin (6) with which the arms (4) and thus the backrest part (2) on the seat part ( 3) is articulated, arranged as to the pin (17) with which the handlebar (7) is articulated on the arm (4). The arm (14) has a recess (15) on its front in the region of its freely hanging end. In the area of the recess (15) of the arm (14), a stop (16) comes to rest when the seating is in the lying position, which is fastened to the inside of the frame (1) in the front area thereof. In the lying position of the seating, the stop (16) is at a distance laterally above the recess (15) of the freely hanging arm (14).

The arm (14) with the recess (15) cooperates with the stop (16) as follows:

In the lying position, the arm (14) hangs freely against the stop (16). To move the furniture from the lying position to the sitting position, the front end of the seat part (3) is raised slightly, whereby the arm (14) engages with the recess (15) in the stop (16). The stop (16) thus briefly forms a fixed pivot point for the seat part (3). By applying slight vertical pressure to the front edge of the seat part (3), the armrest (2) is pivoted or lifted diagonally upwards as a result of the lateral arm (4) which can now be pivoted about this fixed pivot point and which thus briefly forms a two-armed lever. Subsequent slight horizontal pressure on the front edge of the seat part (3) causes the roller (10) to move downwards on the inclined part of the guide (11), thereby bringing the seat part (3) into the sitting position, while the backrest part ( 2) is finally set up. During this »movement, the recess (15) of the arm (14) again disengages from the stop (16).

In order to support the handlebar (7) in the lying position, a further stop (18) is attached to the frame (1). The stop (18) can with a »pad made of soft material, for. B. foam.

A bedding drawer (19) is provided underneath the seat part (3). The bedding drawer (19) is omitted in parts in FIGS. 1 and 2 in order to show the other parts more clearly. The bedding drawer (19) is provided with lateral sliding rollers (20) which are guided in guides (21) of the seat part (3). The essentially horizontal guides (21) are attached to the extension (9) and to the frame part (12). At its front end, the bedding drawer (19) is provided with further rollers (22) by means of which it can be moved on the floor. To limit the movement of the bedding drawer (19) to the front, the seat part (3) is provided with a stop (23); the rear upper edge of the bedding drawer (19) strikes against this. To limit the insertion of the bedding drawer (19) into the seat part (3), a further stop (24) is provided on the guides (21).

To lock the rollers (13) of the seat part (3), notches (25) are provided at the bottom of the furniture frame (1).

According to the variant shown in FIG. 5, the arm (14) need not have a recess (15). R 'arm (14) is rather rounded at its lower end and can be inserted into a bearing (16') provided on the inside of the frame (1) instead of the stop (16).

The described seating is converted as follows: Open to lying position:

Slightly raise the front of the seat section (3) and pull it forward as far as it will go (16). D »Armrest part (2) turns over automatically.

Reach under the bedding drawer (19) with one hand and pull the drawer (19) out as far as it will go (23).

Fold a seat cushion forward over the bedding drawer (19).

Closing to the sitting position:

Fold the seat cushion backwards. Push the bedding drawer (19) under the seat part (3) as far as it will go (24).

Place a backrest cushion (only on models with loose cushions) on the seat.

Raise the seat part (3) slightly at the front until - as described above · the recess (15) of the arm (14) engages in the stop (16). Then apply a slight vertical pressure to the front edge of the seat part (3) and push the latter backwards. Due to its own weight, the seat part (3) slides downwards and backwards, at the same time the backrest part (2) is lifted up.

Push the seat part (3) backwards until the rollers (13) engage in the catches (25).

Set up any back cushion. -3-
