Definitions

  • the invention relates to a stair lift comprising a rail and a frame which is movable along said rail, on which frame a chair is mounted, which chair is fitted with a seat.
  • a stair lift of this kind can be used for conveying a disabled person, who is unable to use the stairs or who is only able do so with difficulty, along said stairs in seated position on said chair.
  • the chair Since a lift of this kind is generally installed along an existing staircase, the space which is available for the stair lift is limited. Especially when the stair lift is not being used, the chair in particular should take up little space.
  • the chair can be fitted with supports, a seat and/or a footrest which can be swung aside.
  • the seat of the chair can for example be pivoted upwards near its rear edge. It is also possible to construct the seat in two parts, whereby the front part can be pivoted upwards.
  • front or front side of the chair are understood to mean the side of the chair remote from the rail which faces in the direction in which the person seated on said chair faces, and the terms “rear” or “rear side” are understood to mean the side of the chair to which a person seated on said chair is turned with his back.
  • the object of the invention is to provide a stair lift fitted with a chair wherein it is possible in a simple manner to move the seat to a position in which it projects less far to the front, by means of a movement which is easy to execute, and which movable seat can be manufactured at low cost.
  • the seat is movable between a front position and a rear position, which positions lie substantially in the same horizontal plane.
  • the upper side of the seat faces up in both positions of the seat, so that only that side of the seat needs to have an aesthetic appearance.
  • the number of positions which the seat can take up need not be limited to two positions. It is also possible to construct the chair such that the seat can be placed in several positions between the front and the rear position.
  • the seat is movable between said two positions by moving the seat at least partially in upward direction.
  • the seat may thereby be mounted in such a manner that it will tilt temporarily during said movement, whereby preferably the front edge of the seat is lifted. This is an operation which is easy to carry out, also for a person who moves with difficulty, because it is a small movement to be carried out at the part of the seat that extends furthest to the front.
  • the seat is connected to the frame near its rear edge by means of a guide which enables a substantially horizontal movement of the rear edge, and near its front edge the seat is connected to the frame via a pivoting arm, which pivoting arm enables the front edge to move along a circular arc.
  • the circular arc thereby lies in a vertical plane in the direction of movement of the seat.
  • the pivot axis of the pivoting arm, or of two pivoting arms, one near each side edge of the seat may be positioned near the underside of the seat, and preferably it is positioned lower, preferably more than 10 mm below the underside of the seat.
  • the above construction makes it possible in an easy manner to create a front and a rear position of the seat, wherein the seat is locked against movement in both positions when a person is seated on the chair.
  • the seat can be locked in both positions, or, if more positions are possible, in all positions, preferably by the downward force which is exerted by a person who is seated on the seat, as described above.
  • a construction of this kind is safe because a separate operation is not required for locking the seat in position.
  • the invention can preferably be used with a stair lift comprising a chair which is fitted with two armrests, which armrests can be moved from the operative position to a position further to the rear.
  • the armrests can slide to the rear thereby or pivot about a horizontal axis.
  • the chair may furthermore be fitted with a footrest which can be moved between an operative, substantially horizontal position and a substantially vertical position. All projecting parts of the chair of the stair lift can thus be moved to a position in which they are not in the way as much.
  • the chair is fitted with a back, and the seat extends to below the back in the rear position, so that the seat is moved maximally rearwards.
  • the rear side of the seat thereby extends approximately as far as the rear side of the back, or further to the rear.
  • the movable seat is provided near its front edge with a downwardly extending protective plate, so that a person cannot easily reach below the seat with his hand, especially while the seat is being moved.
  • a handle is furthermore present near the front edge of the seat. Said handle makes it easier to move the seat, and in addition the presence of the handle shows that the seat can be moved.
  • the invention furthermore relates to a chair for a stair lift which is fitted with a seat which is movable between a front position and a rear position, which positions lie substantially in the same horizontal plane.
  • the invention furthermore relates to a method for manufacturing a chair for a stair lift, wherein the seat of the chair is mounted on a frame and wherein the seat is mounted on a guide which allow movement of the seat between a front position and a rear position, which positions lie substantially in the same horizontal plane.
  • the invention relates to a method for conveying a person by means of a stair lift, wherein the seat of the chair of the stair lift is moved to the front before the person seats himself on the chair.
  • Figures 1, 2 and 3 are schematic side views of a part of a chair of a stair lift, leaving out the front armrest (seen in the direction of the view).
  • the chair is mounted on a frame 1, which is provided with means (not shown) for engaging the rail system of the stair lift.
  • the chair is furthermore fitted with a seat 2, a back 3 and an armrest 4.
  • the back 3 is connected to frame 1 by means of a bracket 5, and armrest 4 is connected to frame 1 by means of bracket 6.
  • the seat 2 is secured to a metal plate 7, which plate comprises a downwardly extending part at the front side, which forms a protective plate 13, which prevents a person from reaching under the seat with his hand without much difficulty. Furthermore a handle 12 is present under the front edge of the seat, which functions to facilitate movement of the seat.
  • the metal plate 7 is provided with a support 8 near the front edge of the seat (on the left in the figures), to which support pivoting arm 9 is pivotally connected. Pivoting arm 9 is connected to frame 1 with its other end.
  • the metal plate 7 is provided with a guide 10 near the rear end of the seat, in which a pin 11 fixed to frame 1 is positioned.
  • a pivoting arm 9 as well as a guide 10 are present on either side of the seat 2.
  • Figure 1 shows the seat 2 in its rear position.
  • the front edge of the seat 2 must be lifted by hand to a position which is shown in Figure 2.
  • the pivoting arm 9 pivots forward thereby and the guide 10 moves with respect to pin 11.
