DE8910549U1 - Furniture unit for placement in a right-angled corner of a room - Google Patents

Abstract

In a furniture unit with horizontally sliding built-in units (3, 4) for installation in a corner of a room, assembly is simplified, adaptability to a wide variety of arrangements and the likelihood of tipping and jamming is reduced in that the storage components (14) are suspended on one side on flat sliding frames (80, 120; 12). The storage components (14) are inserted only after the unit, consisting substantially of flat components, has been pre-assembled. The sliding frames slide longitudinally on guide frames (70, 90; 7) which are also flat. The guide frame (90) of the outer built-in unit (4) can be pivoted about a vertical axis (100). The guide frame (70) of the inner built-in unit is arranged vertically at the rear of the basic unit and secured to the floor by supporting feet (73) and via movable supporting arms (75) to the side walls.

Description

Furniture insert for setting up in a right-angled corner of a room

The innovation relates to a furniture unit according to the preamble of the independent patent claim 1.

When fitting out the interior of kitchens, offices, laboratories or similar, the walls which enclose a 90° angle should, if possible, be filled with furniture. The right-angled corner space is often left free because the furniture filling the corner space is at least partially inaccessible due to the pieces of furniture placed against the two walls.

A furniture unit that avoids this inaccessibility and is intended for installation in a right-angled corner of a room is described in the patent specification CH-593 657. This known furniture unit has two horizontally movable built-in elements, whereby the external built-in element can be pulled out of the base body and pivoted about a vertical axis away from the corner of the room. The two movable built-in elements are connected to one another with levers in such a way that by pivoting the external built-in element about the vertical axis, the built-in element in the corner is displaced horizontally within the base body to the space that was originally occupied by the now pivoted out built-in element. The built-in elements used in the known design each contain a body mounted on a movable frame. The interior of the body is equipped with storage elements, for example in the form of shelves or wire mesh baskets, to accommodate the objects to be stored in the furniture unit. The body can, for example,

This can lead to jamming in the guides. As a result, the horizontally movable components become stiff 15 and the function of the object is impaired.

The innovation is based on the task of improving a furniture unit for installation in a right-angled corner of a room in such a way that assembly is made significantly easier and faster and at the same time the

The main point of the innovation is that the built-in elements are no longer designed in the form of a body with a spatial extension, but essentially consist of a flat frame into which the storage elements are hung on one side after all other components have been assembled.

Fig. 1 shows a furniture unit according to the innovation, where the inner built-in element (3) is in place and the outer built-in element (4) is pulled out of the base body. The base body (1) is, for example, a wooden body which is built into the corner of a room and to which the connecting element (2) is connected. Due to the proximity of the connecting element (2), the inner built-in element (3) of a conventional furniture unit located in the corner is not accessible from the outside.

Above the installation element (3), a rail (7) is mounted in the base body at the front and rear, whereby the rail pair is connected to form a unit by means of cross braces (7a).

The rails (7) can be designed, for example, in the form of a U-profile with the open side facing inwards. In this pair of rails,
The running frame (12) of the inner installation element (3) is mounted on rollers (15) and can thus be moved in the longitudinal direction. The support frame (8) of the outer
Installation element (4) is located on the inner
The outer installation element (4) is mounted on the side facing away from the installation element (3) and is mounted so that it can move on a guide rail (9) connected to the base body (1). The guide rail (9) which accommodates the support frame (8) of the outer installation element (4) can also be pivoted about a vertical axis (10). The outer installation element (4) can thus be pulled out of the base body (1) starting from the basic position (not shown) and thus reaches the position shown in Fig. 1. When the outer installation element is pivoted about the vertical axis (10) into the position shown in Fig. 1 with a dotted line, an angled lever (5) attached to the pivoting guide rail (9) is deflected. This lever (5) is pivoted about a pivot point (5a) fixed on the base of the base body.
pivotable and in the area between the rail-side pivot point (5c) and the pivot point (5a) as a guide
(5b) so that the articulation point (5c) mounted in the guide (5b) can be moved in the direction of the pivot point when the installation element is pivoted along the guide (5b). This kinematic connection means that the inner installation element (3) can be pivoted by means of a further pivotally attached to the other end of the lever (5).
lever (6) in a known manner along the rail (7) of
its original place on the now vacant,
is moved to a place accessible from the outside (cf.
The position of the levers (5, 6) is shown in dash-dotted lines.

Fig. 2 shows a view of the movable and

pivotable fastening of the outer built-in element (4) on the base body (1). The support frame (8) of the outer built-in element (4) is arranged so that it can move by means of a roller (11) fastened to the guide rail (9) and is additionally supported by the support roller fastened to the support frame and rolling on the guide rail (9). The upper part of the support frame (8) is designed as a guide rail (8a) and is guided by means of guide rollers (9b) running therein and connected to the base body = The lower guide rail (9) and the upper guide rollers (9b) supporting the guide rail (8a) are attached to a support plate (9a), which support plate is pivotably connected to the base body of the furniture unit via the vertical axis (10). In the extended state (not shown), the entire outer installation element (4) together with the components supporting the installation element can be pivoted about the vertical axis (10). Via the levers (5, 6), this pivoting movement of the outer installation element (4) is coupled with the sliding movement of the inner installation element (3) as described, so that the inner installation element (3) takes up the space originally occupied by the outer installation element (4) when the inner installation element (4) is fully pivoted out.

Fig. 3 shows a perspective view of the inner installation element (3) that can be moved on a pair of rails (7). The rails (7) connected to form a unit by means of cross braces (7a) are firmly attached above the installation elements in the base body (1). The inner installation element (3) consists of a carriage (12), a support frame (13) that is open at the top and a number of storage elements (14) that are attached to it so that they hang on one side. The carriage (12), which can be moved on the rails (7) via rollers (15), consists of a carriage made of a pair of longitudinal braces.

(16) and cross struts (17) and a diagonal strut/ from which vertical struts (18) extend downwards at the rear edge. The lower end of the vertical struts (18) is connected by means of support struts (19) to the front area of the frame, ie to the front area of the cross struts (17), for the purpose of absorbing bending moments acting on the vertical struts (18). The vertical struts (18) of the wa- Qona ( 1 0 } cinH imr7uneuei eo auc T.-Prnf ilpn apbilde>h And Tiit the frame formed from the longitudinal and transverse struts (16, 17). The vertical struts (18) are each provided in the upper area with a hole (20) running in the longitudinal direction of the rail (7). Support bolts (21) are each firmly connected, e.g. welded, to the upper end of the support frame (13) of the inner installation element (3). The distance between the two vertical struts (18) is such that the support frame (13) just fits between the L-profiles. After the support frame has been assembled, the support bolts (21) engage with the holes (20) provided in the vertical struts (18).

To assemble the support frame (13), it is pressed together in the open upper area so that the outer ends of the support bolts (21) can be inserted into the holes (20) from the inside. When the pressure on the support frame (13) is released, it springs back and now hangs on the support bolts (21) located in the holes (20) and its position is simultaneously fixed by the L-profiles of the vertical struts (18). In particular, the rear cheeks (18a) of the L-profiles prevent the hanging support frame from swiveling backwards.

In the assembled state/ i.e. when the installation elements (3, 4) with the components supporting them and the levers (5,

6) are inserted into the base body, can now be ^

Storage elements (14) in the desired number and on the £*

desired height of the respective support frame (8, 13) |

§

Each storage element (14) has a

Pair of fastening elements (23), each of which has a

a straight arm forming the support arm (24) and a '

Contains an angled arm forming a pulling arm (25). ;

The fastening elements (23) can either be an integral part of the storage element (14) or can be designed in the form of fittings which are mounted on the corresponding sides of the storage element (14). The storage element itself can either be a flat basket consisting of a grating, a bowl-shaped body (not shown) or a plate-shaped body (not shown). In the first-mentioned design of a storage element consisting of a grating, the fastening elements are preferably an integral part of the storage element.

A storage element designed in this way preferably consists, as can be seen in Fig. 3, of a lower frame (26) and an upper frame (27), which two frames are connected to one another by means of connecting struts (28). Cross struts (29) arranged in the lower frame form the storage base, which can be used either in the form shown or covered by a plate. The parts of the lower frame (26) that extend beyond the front edge of the storage element (14) form the support arms (24) and the protruding parts of the upper frame (27) form the tension arms (25).

In the other possible designs of the storage,

element, a fitting containing the support arm and the pull arm is attached, for example, to the two corners of one side of the storage element (not shown* .

Fig. 4 shows a storage element connected to the support frame , having vertically extending, consecutive struts (30, - 31) which are firmly connected to one another. These are preferably components of a U-profile. The front strut (31) is provided with holes (32), whereby a pair of holes is required on each side to fasten a storage element, which holes must be spaced apart by the vertical distance of the support arm from the tension arm. Preferably, the strut (31) has a plurality of holes which are arranged at a constant distance.

To mount the storage element, it is tilted upwards so that the angled part (25a) of the pull arms is approximately horizontal. In this orientation (shown in dash-dotted lines), the two pull arms (25) on the storage element (14) are inserted into the holes (32) in the front strut (31) of the support frame. The pull arms (25) inserted into the holes (32) are pushed into the hole until almost the entire non-angled part (25) of the pull arm has passed through the hole to the inside. If the inclination of the storage element is only slightly changed, the tips of the support arms are slightly below and in front of the holes (32a) intended for receiving the support arms. If the storage element (14) is now swiveled into the horizontal position, the support arms (24) slide through the lower holes (32a). The support arms (24) slide through the hole until their tips are at the rear

Strut (30) of the support frame rests and is supported there. During this pivoting movement, the angled part of the pull arm is in an upward-pointing position. In this position, the box of the angled part of the pull arm is on the inside of the front strut (31) of the support frame above the hole sj3„ This means that the pull arm can no longer slide outwards through the hole. To avoid jamming when inserting the fastening element into the support frame as described here , the hole grooves provided in this must be cut to an appropriate size.

The tensile forces occurring in the support arm as a result of the support element (14) being suspended on one side are transmitted via the bent part (25a) of the tension arm (25) to the inside of the front strut (31) of the support frame. A horizontal alignment of the storage element (14) is ensured by the fact that the difference in length between the support arm and the non-bent part (25a) of the tension arm (25) is equal to the clear distance between the front strut (31) and the rear strut (32) of the support frame.

The design of the fastening elements in the form of a support arm and a tension arm means that the torque acting on the support frame resulting from the one-sided support of the support elements is converted into a tensile force and a compressive force. The tensile force is transmitted via the non-bent part (25a) of the support arm to the inside of the front strut (31) and the compressive force is transmitted via the support of the tip of the support arm (24) against the inside of the rear strut (30). The downward weight forces are transmitted via the holes (32/ 32a) to

-&igr;&ogr;transferred to the supporting frame.

The vertical struts (IS) *5-3:v of the support frame, preferably designed in the form of an L-profile, are extended downwards and supported by means of support screws (19) on the front part of the carriage (12). By supporting the support frame on the rear part of the L-profile (18?), the torque acting in the support frame around the support bolts (21) is absorbed and a vertical alignment of the support frame is ensured.

IQ Using the innovation presented, a furniture unit for installation in a right-angled corner of a room can be made using simpler means and fewer parts than before, the assembly of the built-in elements, which essentially consist of flat parts, can be made much easier and operational safety, i.e. safety against jamming and blocking of the moving elements, can be significantly increased.
