Definitions

  • the present invention relates to a chair, to a method for assembling thereof, and to a method for disassembling thereof.
  • a further object of the invention is to provide a chair with an attractive appearance.
  • a further object of the invention is to provide a chair with an appearance which can be adapted easily and quickly. According to a first aspect of the invention, at least one of the above stated objects is achieved in a disassembling chair, comprising:
  • lying panels are provided with protrusions which are embodied for sliding into and out of corresponding recesses for the purpose of respectively assembling and disassembling the chair; wherein at least one of the protrusions of one of the lying panels is provided with a locking opening in which, in assembled state, a locking element is slidable for the purpose of locking the lying and standing panels to each other, wherein the locking element comprises a locking panel slidable behind the rear panel.
  • the chair can be put together and taken apart in simple manner by sliding the various components thereof. Locking of the chair in assembled state takes place by sliding the locking element into said locking opening, while unlocking takes place by removing the locking element from the locking opening. It is hereby possible to assemble and disassemble the chair in simple manner without special tools being required for the purpose.
  • the locking element comprises a locking panel slidable behind the rear panel. The panel herein preferably extends parallel to the seat back so that a flat rear side or seat back of minimal thickness can be realized.
  • the chair is provided with a holder which is slidable behind the rear panel and in which a graphic image element can be arranged, wherein the holder is adapted to position the image element behind a viewing opening provided in the rear panel for making the image visible from the front side of the chair.
  • the holder is formed by the locking panel which slidable behind the rear panel.
  • the appearance of the chair is embellished by adjusting the appearance of the seat back using an image which can be placed in the holder.
  • the image can be formed by an electronic screen, such as an LCD screen, on which the still or moving image is shown.
  • a photograph of a child can be arranged in the holder so that the whole chair acquires an appearance specific to the child in question. If the chairs are being used for instance in a classroom, each child can thus have a chair personalized to its own appearance.
  • the above mentioned locking element is formed by the holder.
  • the holder hereby has a dual function, i.e. the function of carrying the image and the function of locking the chair.
  • each of the side panels is provided with an upright recess into which both the rear panel and the locking panel are slidable.
  • the upright recess is moreover preferably formed such that the image element is received, preferably clamped, in the intermediate space between the rear panel and the locking panel. In this way the image element can be positioned quickly and easily without additional fastening means being necessary.
  • two mutually opposite edges of a lying panel are provided with first protrusions over which recesses in the side panels are laterally slidable. In assembled state, i.e. when the side panels have been pushed over the protrusions, the lying panel absorbs the laterally inward directed forces on the chair, and the panel holds the side panels, the top sides of which preferably serve as armrests, in the correct straight position.
  • two opposite edges of the lying panel are provided with hook-like second protrusions for hooking onto the side panels.
  • a lying panel In assembled state, i.e. in a situation in which the protrusions hook onto the side panels, such a lying panel can absorb the laterally outward directed forces on the side panels. This prevents the side panels moving outward when a person sits on the chair.
  • the bottom panel is provided with first protrusions and the top panel is provided with second protrusions. Since a person will sit on the top lying panel, the greatest forces on the top lying panel will in most cases be directed laterally outward. In order to absorb these forces it is therefore recommended to embody the top lying panel, i.e. the panel on which the person sits, with the above stated measures for absorbing the outward directed forces, so that a more stable construction can be realized.
  • the panel with the protrusion provided with a locking opening is also provided with the second, hook-like protrusions.
  • a lying panel can be pushed beforehand between the side panels.
  • the lying panel provided with the hook-like protrusions is pushed in such that the protrusions hook around the side panels, in this embodiment other protrusions simultaneously slide into the recess in the back panel. This means that in a single movement the lying panel hooks onto the side panels and provides a locking option for all other components of the chair, i.e. the side panels and the rear panel.
  • the side panels are provided with recesses at different heights for height-adjustment of at least the top lying panel.
  • this can be realized by arranging the top lying panel and, optionally although not necessarily, also the bottom lying panel in the correct recess.
  • the hook- like, second protrusion can be partially received in a recess provided in an edge of a standing side panel, whereby the protrusion is as it were at least partially taken up in the recess when the chair is in the position of use. This enhances the appearance of the chair.
  • This construction moreover provides the option of arranging a locking element in a manner to be described hereinbelow.
  • the protrusion provided with a locking opening is slidable into a recess provided in the rear panel as discussed above.
  • the locking opening is herein positioned on the rear side of the rear panel, wherein a part of the locking element extends through the locking opening.
  • a chair comprising a standing left side panel, a standing right side panel, a lying panel forming the chair seat and a standing rear panel forming the chair back, in addition to a holder in which an image element such as a graphic image can be arranged, wherein the holder is adapted to be positioned behind a viewing opening provided in the rear panel for making the image visible from the front side of the chair.
  • the holder comprises a panel slidable behind the rear panel, wherein the image element can be held fast between said slidable panel and the rear panel.
  • This slidable panel can be the above mentioned locking element, but can also be formed by a separate plate.
  • each panel can hereby be supplied separately and in different embodiments, for instance different colours, so that the chair can be assembled in accordance with personal taste.
  • a method for disassembling a chair as described herein comprising of:
  • figures IA and IB are respective perspective front views of a first preferred embodiment which show the fastening of the seat panel to a side panel
  • figures 1C and ID are respective perspective front views of the first preferred embodiment which show the fastening of the seat panel at a higher position to a side panel
