Definitions

  • the present invention relates to a device for making a two-dimensional movement in a vertical plane, and spe ⁇ cifically to such a device for moving a wall cupboard away from a wall and downwards.
  • a device for making a two-dimensional movement in a vertical plane and spe ⁇ cifically to such a device for moving a wall cupboard away from a wall and downwards.
  • Persons who are tied to their wheelchair or disabled in some other manner find it difficult, in for instance a kitchen, to reach into fixed wall cupboards at a high level above the floor. It is therefore known to make wall cupboards lowerable either merely downwards or both down- wards and away from the wall.
  • SE-B-455,153 discloses a device having a parallelogram link for moving a wall cupboard outwards and downwards, thereby improving the accessibility of the interior of the cupboard.
  • the prior-art device however, has a limited range of motion and utilises an additional mechanism for further moving the wall cupboard vertically.
  • the object of the present invention is to provide a simple device of the type stated by way of introduction, which alone yields a great range of motion and which is operable with the aid of a single drive means.
  • the device should on its own permit the desired movement from the usual position of a fixed wall cup ⁇ board to a lowered and pulled-out position, in which the accessibility of the interior of the wall cupboard is satisfactory also to a disabled person.
  • the device should preferably also be accommodated between the wall and the wall cupboard when this is in its upper position.
  • a scissor-type link having two link arms which are mutually turnable in said vertical plane. The ends of one link arm are each turn- ably connected to one of the guide rods, while the ends of the other link arm are each connected in a turnable manner relative to one of the guide rods as well as in a displaceable manner along the same.
  • a drive means is used for mutual turning of the link arms and, thus, two-dimensional movement of the guide rods rela ⁇ tive to one another.
  • the in- vention is not restricted to this application but is generally usable for performing a two-dimensional move ⁇ ment of an object in a vertical plane.
  • the link arm end which is merely turn- ably connected to the fixedly mounted guide rod is posi ⁇ tioned below the link arm end which is both turnably and displaceably connected to the same guide rod. Also the link arm end which is merely turnably connected to the movable guide rod, is positioned above the link arm end which is both turnably and displaceably connected to the same guide rod.
  • the drive means is suitably connected between the link arm ends connected to the fixedly mounted guide rod and may, in the case involving a wall cupboard, when the fixedly mounted guide rod is attached to a wall, be accommodated between the wall and the wall cupboard when this is in its upper position.
  • FIG. 1 is a side view of an inventive device used for a wall cupboard and shows this in its upper position
  • Fig. 2 is a side view corresponding to Fig. 1, show- ing the wall cupboard in a lower and outer position.
  • the drawing illustrates a wall cupboard 1 mounted on a wall 2 by means of a device according to the invention.
  • the device comprises more specifically a first guide rod 3, a second guide rod 4, a scissor-type link 5 having two link arms 6 and 7 and a drive means 8.
  • the first guide rod 3 is fixedly mounted on the wall 1 with the aid of wall fastening means 9 and 10.
  • the second guide rod 4 is fixed to the rear side of the wall cupboard 1 by cupboard fastening means 11 and 12.
  • the two link arms 6 and 7 are turnable in a vertical plane about a common pivot pin 13.
  • the one end 14 of the link arm 6 is turnably con ⁇ nected to a lower part of the guide rod 3 by means of a pivot coupling 15 which is fixed to the guide rod 3.
  • the other end 16 of the link arm 6 is in the same manner turnably connected to an upper part of the guide rod 4 by means of a pivot coupling 17 which is fixed to the guide rod 4.
  • the one end 18 of the link arm 7 is turnably and displaceably connected to the guide rod 3 by means of a pivot coupling 19 which is fixed to a sleeve 20 which is movable along the guide rod 3.
  • the other end 21 of the link arm 7 is turnably and displaceably connected to the guide rod 4 by means of a pivot coupling 22, which is fixed to a sleeve 23 which is movable along the guide rod.
  • the drive means 8 which can be an electrically, pneumatically or hydraulically operated cylinder assem ⁇ bly, is connected to adjust the distance between the end 14 of the link arm 6 and the end 18 of the link arm 7 by being connected between the pivot couplings 15 and 19.
  • the pivot coupling 19, 22 can be integrated with the sleeve 20 and 23, respectively.
  • the drive means 8 has moved the end 18 of the link arm 7 closer to the end 14 of the link arm 6, i.e. down to the latter to, for instance, a predetermined limit position, in which the other end 16 of the link arm 6 has been pivoted downwards and outwards from its position in Fig. 1, and the other end 21 of the link arm 7 has been moved closer to the other end 16 of the link arm 6.
  • the cupboard 1 Since the pivot pin 13 in the embodiment illustrated is arranged in the centre of the two link arms 6 and 7, the cupboard 1 will be moved in parallel when activating the drive means 8. A parallel movement of the cupboard 1 is generally effected if the length of the parts of the link arm 6 on both sides of the pivot pin 13 is equal to the length of the corresponding parts of the link arm 7 on both sides of the pivot pin 13. It is thus obvious that it would be possible to move the cupboard 1 from the position shown in Fig. 1 to a position which is not parallel to this by giving the parts of the link arms 6 and 7 on both sides of the pivot pin 13 other lengths than the said ones.
  • the inventive device makes it easy to guide the cupboard to a desired position outside the wall 2 and below the position shown in Fig. 1.
  • the ends 14 and 16 of the link arm 6 which are turnably connected to the guide rod 3 and 4, respectively, need not be connected directly thereto, but may just as well be indirectly connected by means of the wall 2 and the wall cupboard 1, respectively.

Abstract

Dispositif permettant le mouvement bidimensionnel d'un placard (1) dans un plan vertical, comportant deux tiges guides (3, 4), une liaison en ciseaux (5) et un dispositif d'entraînement (8) permettant de régler la liaison en ciseaux. Une tige guide (3) est montée de façon fixe dans une position sensiblement verticale et l'autre tige guide (4) est mobile par rapport à la tige guide montée de façon fixe et supporte le placard (1). La liaison en ciseaux (5) comporte deux bras de liaison (6, 7) rotatifs l'un par rapport à l'autre dans le plan vertical mentionné. Les extrémités (14, 16) d'un bras de liaison (6) sont chacune reliées de façon rotative à une tige guide (3, 4) et les extrémités (18, 21) de l'autre bras de liaison (7) sont reliées de façon à pouvoir se déplacer le long d'une tige guide. Le dispositif d'entraînement (8) fait tourner les bras de liaison (6, 7) l'un par rapport à l'autre et entraîne de ce fait un déplacement bidimensionnel du placard (1).
