Definitions

  • the invention relates to a wheel mechanism, by means of which the wheel can optionally be extended or retracted, depending on whether the mechanism is wanted to be in a movable or stationary position, in relation to the base.
  • Devices like this facilitate, e.g. in homes and workshops, the movement of articles which have to stand steadily in their place while being used.
  • the transporting means are taken into operative engagement only when the articles have to be moved.
  • Movable articles are known to be fitted with wheels which can be locked when necessary. Thus the article stays in its position, but can also be moved when needed.
  • E.g. refrigerators, freezers, washing machines, stoves; 3-piece suits, cabinets etc. are typical examples of such articles in homes.
  • Especially household machines need to be moved occasionally, i.a. for cleaning. They are, however, difficult to move and so maintenance and cleaning may easily be neglected. This may result in the machine breaking down or becoming dirty to such an extent as to cause e.g. a risk of fire.
  • the invention is characterized in that the wheel mechanism comprises means for allowing a vertical movement of the wheel when the mechanism is being lifted, and that the mechanism comprises a locking device, which locks the wheel into a movable position at every second lift of the mechanism.
  • the invention offers a particularly favorable solution e.g. in a case when a freezer located in a narrow space has to be moved temporarily.
  • Figures 1 to 4 show the stages of how to change a cupboard, fitted with wheel mechanisms in accordance with the invention, into a movable position.
  • Figure 5 shows a cross-section of the wheel mechanism of the invention.
  • Figures 6 to 10 show the stages of how to bring the mechanism in figure 5 into operative condition.
  • Figures 11 to 15 correspond to figures 6 to 10 and show the stages of how to return the mechanism into a non-operative state.
  • Figure 1 illustrates any cupboard 10, difficult to move and located in a narrow space e.g. a freezer, difficult to move, when placed in a niche and standing on the floor 9.
  • the cupboard 10 when fitted with the wheel mechanisms relating to the invention, can however be made easily movable by tilting it.
  • the cupboard 10 To bring the cupboard 10 into a movable position, it must first be tilted, as seen in figure 2, e.g. by pushing the top part.
  • the cupboard will tilt backwards on the rear legs 1, and the front legs will raise up from the floor. Now the mechanisms in the front legs will extend the wheels 2 therein.
  • the front leg wheels 2 When the tilting on the rear legs is ended and the article is lowered back onto the floor 9, the front leg wheels 2 will remain in an operative position.
  • the cupboard 10 is tilted in the opposite direction, as seen in figure 3, the front legs, standing on wheels 2, acting as support points. This can be done by holding the cupboard in its position by means of a foot 8, and by simultaneously tilting it forward against oneself.
  • the rear legs have been raised up from the floor, their wheels 2 will be extended into an operative position and get locked.
  • the cupboard 10 is now extended back on its legs, it will be in a movable condition with all wheels 2 lowered, as can be seen in figure 4.
  • Figure 5 shows a cross section of the wheel mechanism relating to the invention.
  • the mechanism includes a wheel
  • a spindle 12 joins the wheel through a bearing to the bottom end of a connecting piece
  • a swinging cam 4 is attached to the opposite end of the connecting piece 3 by means of another spindle 14.
  • the wheel unit consisting of the connecting piece 3, the wheel 2, and the cam 4, is movable up and down in a duct 16 inside a frame 11. Furthermore, inside the cam 4 there is a slot 17, in which a slide 5 is able to move freely. The slide 5 acts by turning the cam alternately from side to side.
  • Figure 5 shows the mechanism in the position with the wheel 2 supported against the floor 9. Then, as seen in the picture, the swinging cam 4 is tilted to the left and a tip 13 of the cam rests against a support point 7 of the frame 11. The slide 5 in the slot 17 inside the cam has freely dropped against the wall of the frame 11. When the whole mechanism is lifted upwards, the slide 5 will turn the tip 13 of the cam 4 to the opposite side and the wheel 2 will be retracted inside the frame. The operation is shown more clearly, stage by stage, in the following figures.

Abstract

L'invention se rapporte à un mécanisme à roue, au moyen duquel une roue (2) peut être au choix soit rentrée soit sortie, selon qu'on désire que le mécanisme puisse se déplacer ou rester en position fixe par rapport au sol (9). Ce mécanisme à roue comprend des organes (3, 16), qui permettent un mouvement vertical de la roue (2) lorsqu'on soulève le mécanisme, lequel comporte également un dispositif de blocage (4, 5, 7), qui bloque la roue en position de déplacement à chaque deuxième man÷uvre de soulèvement du mécanisme, c'est-à-dire une fois sur deux.
