Definitions

  • the present invention relates to a dynamic chair which has an unstable support on the floor during use, so that in order to compensate for this instability a user must compensate with the support on the floor of his feet by necessarily exercising certain muscle groups of his body, fundamentally of his feet and legs; all this so that the user can remain stable in the seated position on the chair, a position in which the seating surface of the chair is situated in a substantially horizontal plane.
  • the field of technology in which the present invention is concerned is furniture, and more specifically seating furniture.
  • Some chairs are also known to have arched glides attached to the ends of pairs of legs, where the arched glides are the elements that support the floor so that a user can balance while seated in the chair. support the floor so that a user can balance while seated in the chair.
  • the invention proposes a dynamic chair comprising a seat body attached to a frame located underneath the seat body; wherein said frame includes a first upper end part attached to the seat body, a lower end part opposite the upper end part.
  • the dynamic chair further comprises a base attached to the lower end region of the frame; wherein said base includes a protruding central protuberance as a means of unstable support on the floor of the dynamic chair; and wherein the central protuberance protrudes below a lower perimeter surface of the base.
  • the chair includes an electrical circuit comprising an electrical cable; where one end of the electrical cable is connected to a first metal part attached to the seat body, while another end of the electrical cable is connected to a second metal part attached to the central protuberance, while in contact with the floor during use of the chair.
  • the power cable is configured to receive, conduct and shunt static electricity to ground that may accumulate on a user seated in the chair.
  • the frame is formed by tubes which coincide with the edges of a parallelogram, while the base consists of a hollow body with a lamellar structure.
  • the electric cable runs through the inner space of some of the frame tubes and also through the inner space of the base.
  • the frame is reinforced by an annular body which is attached to the central part which is part of the frame.
  • the seat body comprises a platform and a backrest which are connected by means of a curved section, while the platform includes a smooth central concavity and a downwardly extending front flange.
  • the platform of the seating body includes lower appendages extending from a bottom face of the seating body platform; wherein said lower appendages are configured to engage upper end sections of tubes forming part of the frame; and wherein the connection between the seat body and the frame comprises bolts relating the lower appendages and said upper end sections of tubes of the frame.
  • the back of the upper seat body includes at least one hole that is configured to grip and hold the chair during handling and moving.
  • the frame of the chair is made of metal, while the base and the seat body are made of a plastic material, so that the frame is attached to the base by means of a bolted connection.
  • the central protuberance of the base has a spherical cap- shaped configuration.
  • the dynamic chair comprises a seat body (1), a frame (2) of tubular structure, and a base (3); wherein the seat body (1) is, configured to allow a user to sit during the use of the chair.
  • the base (3) has a circular shape.
  • the base (3) of the chair is configured to rest on the ground in an unstable manner during the use of the chair, so that for this purpose said base (3) includes in its center a central protuberance (4) in the form of a spherical cap; where during the use of the chair of the invention, in order to compensate for its instability, the user must compensate it with the support on the ground of his feet necessarily exercising certain muscle groups of the body, mainly the back, feet and legs, so that the user can remain stable in the seated position on the chair.
  • the user seated in the chair of the invention continuously exercises these muscle groups in a comfortable and easy way, precisely because of the instability of the chair's floor support during use.
  • the chair of the invention can be useful in the prevention of lumbago and other pathologies, by counteracting the negative effect exerted by prolonged sitting and also, help in overcoming various ailments, especially back problems.
  • the instability of the chair is limited, thus hindering tipping over, by means of perimeter parts of the base (3) which are around the central protuberance (4), so that in the embodiment shown in the figures, said perimeter parts refer to a perimetral corner edge (5) of the base (3), although in another embodiment of the invention not shown in the figures, these perimeter parts could be, for example, appendages that protrude from under the lower base (3) at a lower height than the central protuberance (4).
  • the chair of the invention further includes an electrical circuit comprising a single-phase electrical cable (6) configured to receive and conduct static electricity to ground that may accumulate on a user seated in the chair.
  • one end of the electrical cable (6) is connected to a first metal part attached to the upper seat body (1), while the other end of the electric cable (6) is connected to a second metal part (8) attached to the central protuberance (4) and in contact with the floor.
  • a second metal part (8) attached to the central protuberance (4) and in contact with the floor.
  • the electric cable (6) runs along the inside of some of the tubes that make up the frame, while another section of the electric cable (6) runs along an interior space of the lower base (3), which has a hollow structure.
  • the frame (2) is formed by metallic tubes that coincide with the edges of a parallelepipedic body; where four of said tubes are arranged in vertical directions with a circular cross-section, four others are arranged in a first horizontal plane with a rectangular cross-section coinciding with the seat body (1) and four others are arranged in another horizontal plane coinciding with the base (3).
  • the frame (2) can also be reinforced by means of an annular body (9) of cylindrical-tubular section arranged at mid-height.
  • the seat body (1) comprises a platform (1a) and a low backrest (1b) which are connected by a curved section (1c), while the platform (1a) includes a smooth central concavity (10) and a downwardly extending front flange (11).
  • the platform (1a) of the seat body (1) includes lower appendages (12) that start from an underside of said platform (1a), so that said lower appendages (12) are configured to be embedded in upper end sections of the four vertical tubes that form part of the frame (2), ensuring the connection between the seat body (1) and the frame (2) by means of screws not shown in the figures.
  • the backrest (1b) of the seat body (1) has two holes (13) through which the fingers of a user's hand can be inserted to grip and hold the chair assembly more easily during handling and transport.
  • the frame (2) is made of metal, while the base (3) is made of a plastic material such as polypropylene.
  • the seat body (1) is also made of polypropylene, so that the frame (2) is joined to the base (3) by means of a bolted connection.
  • the height of the chair of the invention can be between 40 cm. and 50 cm., without ruling out other sizes, of course, by varying the height of the frame (2).
