Definitions

  • the invention relates to the folding armchair assembly and is used to lift the footrest from a vertical position.
  • the folding armchairs which can be modified from a sitting position to a lying or reclining position for sleeping are known.
  • a lifting of the footrest and a reverse tilt of the armchair back takes place.
  • the change in the position of the armchair back may be connected with the movement of the footrest or the armchair back may change position independently of the other mechanisms.
  • the known armchair contains a seat and a footrest, which are pivotally connected to each other.
  • the footrest lifting mechanism rotates it 180 degrees so that in the folded position the footrest is horizontally under the seat and parallel to it, and in the raised position it is horizontally in front of the seat.
  • the known mechanism On either side of the seat the known mechanism is equipped with two curved elements pivotally connected to each other (front and rear), one of which (front) is connected to the footrest, and the other (rear) is connected to the seat.
  • the mechanism contains a shaft rigidly connected to the rear curved elements in the place of their connection with the footrest.
  • an additional element is fixed at one end, which is identical to the rear elements and located parallel to them.
  • the additional element is pivotally connected to the gas strut.
  • the gas strut rotates the additional element, which in turn transmits torque to the shaft.
  • the shaft transmits torque to the rear curved elements, which move the front curved elements.
  • the front curved elements rotate the footrest relative to its swivel joint with the seat to the unfolded position.
  • the technical result of the invention is an increase in the range of the technical means, development of a simple to manufacture and reliable mechanism for lifting the footrest in the folding armchair.
  • a mechanism for lifting the footrest in the folding armchair which includes a fixed seat and an associated swivel footrest, including a base, the first and the second connecting elements, each of which is rigidly connected at one end to the base, and at the other end is pivotally connected to the seat, while the connecting elements are in the form, the base part of which is U-shaped, and in the area of connection with the seat they contain the inward elbow with the upper and lower sides, in which at least one connecting element contains the swivel joint with the pusher located in the seat, while the axis of the upper side of the elbow forms an angle with the axis of the pusher less than 180 degrees.
  • the proposed invention is illustrated with the graphic material.
  • FIG. 1 the folding armchair with the footrest in the folded (upright) position is shown.
  • FIG. 2 the folding armchair with the footrest in the raised position is shown.
  • FIG. 3 the connecting element is shown.
  • FIG. 4 the connecting element and the pusher in the folded position of the footrest are schematically shown.
  • FIG. 5 the exterior of the folding armchair with the footrest in the folded position is shown.
  • FIG. 6 the exterior of the folding armchair with the footrest in the raised position is shown.
  • the armchair contains fixed seat 1 , footrest 2 , armchair back 3 and armchair legs 4 .
  • Seat 1 is a frame that includes upper part 5 and lower part 6 .
  • Footrest 2 includes base 7 and first and second connecting elements 8 , one on each side of seat 1 .
  • First connecting element 8 at one end is rigidly connected to base 7 at point 9 , and the other end is pivotally connected to seat 1 at point 10 . Therefore, point 10 is the pivot point of footrest 2 .
  • the second connecting element (not shown in the figure) is located on the other side of the armchair and, like the first one, is rigidly connected to base 7 at one end, and is pivotally connected to seat 1 at the other end.
  • the first and the second connecting elements are in the form, the base part of which is U-shaped and contains front side flange 11 , rear side flange 12 and lower flange 13 connecting them.
  • Rear side flange 12 contains inward elbow 14 .
  • Elbow 14 has two sides—upper side 17 and lower side 18 .
  • First connecting element 8 in the area of elbow 14 is pivotally connected at point 15 to pusher 16 .
  • Upper side 17 forms a lever arm: the distance between the point 10 and point of connection 15 with pusher 16 .
  • the axis of side 17 forms the angle ⁇ with the axis of pusher 16 , which is less than 180 degrees.
  • Pusher 16 can form a gas strut located in the seat between the upper part of frame 5 and the lower part of frame 6 .
  • the proposed mechanism is associated with the movement of the armchair back.
  • second connecting element 8 at point 15 is pivotally connected by the rigid tie rod to the back of the armchair for the synchronous transformation.
  • the above-noted rigid tie rod interacts with the lever (not shown in the figure), which allows you to lock its position.
  • the force of the adjustable gas strut and the length of the lever arm are selected in such a way that when unlocking the rigid tie rod it helps to lift the footrest more easily and has an optimal slight resistance when folding.
  • the weight distribution of the back and the footrest are in balance and the lifting of the footrest and the back tilt can be easily stopped in any comfortable position.
  • the proposed mechanism is not associated with the movement of the back of the armchair.
  • the second connecting element is pivotally connected to the other independent gas strut.
  • seat 1 and footrest 2 have upholstery 19 and 20 , respectively, which completely covers their upper portions and the butt ends.
  • the elements of the proposed mechanism are completely hidden from the eyes of the consumer.
  • the footrest In the raised position the footrest is spaced from the seat at a certain distance, which provides a comfortable position for the seated person, in which his feet with the posterior malleolar part lie on this footrest.
  • angle ⁇ which is less than 180 degrees, under the elongation of the gas strut ensures rotation of the lever arm (side 17 ) around point 10 only clockwise.
  • the maximum raised position of the footrest is shown in FIG. 2, 6 .
  • the proposed mechanism is simple to manufacture and reliable in use, while its elements do not compromise the integrity of the armchair upholstery visible to the consumer.
