Definitions

  • the present invention relates to a folding frame with increased safety, particularly for high-chairs and the like.
  • U.S. Patent Application No. 09/122,696 of July 27, 1998 discloses a joint for producing folding trestle-like frames for high-chairs and the like which is substantially constituted by an internal body connected to the ends of U-shaped frames and forming a seat for the sliding of a pivot which joins bars for connection to the arms to be joined.
  • An external body is slidingly mounted on the internal body and can perform a translatory motion so as to change position in order to pass from a closed position to an open position and/or viceversa.
  • This embodiment which is valid from many points of view, is however susceptible of improvement especially as regards safety and particularly in order to prevent accidental closures of the frame.
  • the joint may in fact remain in an intermediate position, so that accidental movements may cause the frame to close, with obvious consequent drawbacks.
  • Another problem is also constituted by the fact that if the external bodies are released accidentally, the two U-shaped frames may be movable with respect to each other.
  • the aim of the invention is to solve the above problems by providing a folding frame with increased safety, particularly for high-chairs and the like, in which means are provided which tend to keep the frame in the open position, thus preventing accidental and unintentional closures.
  • a particular object of the invention is to provide a folding frame in which it is possible to use joints which can be derived, from a structural point of view, from those used previously without thereby having to perform complicated or troublesome modifications.
  • Another object of the present invention is to provide a folding frame which, thanks to its particular constructive characteristics, is capable of giving the greatest assurances of reliability and safety in use.
  • Another object of the present invention is to provide a folding frame with increased safety, particularly for high-chairs and the like, which can be easily obtained starting from commonly commercially available elements and materials and is also competitive from a purely economical point of view.
  • a folding frame with increased safety, particularly for high-chairs and the like comprising a framework which is constituted by a first U-shaped frame and a second U-shaped frame which are joined, at their ends, by joints, each of which is provided with an internal body, which is hinged to the end of said U-shaped frames and forms a guiding slot for the sliding of a pivot for connecting two bars which are pivoted, at one end, to said U-shaped frames, an external body being also provided which is connected to said connecting pivot and can perform a translatory motion in order to arrange said U-shaped frames in a closed position, in which said U-shaped frames are mutually side by side, and in an open position, in which said U-shaped frames are mutually inclined, characterized in that it comprises, in at least one of said joints, elastic means which are adapted to push said U-shaped frames into the open position.
  • the folding frame with increased safety, particularly for high-chairs and the like generally designated by the reference numeral 1 is substantially constituted by a framework which is provided by means of a first U-shaped frame 2 and a second U-shaped frame 3, which are provided with castors 4 and which are pivoted, at the free ends of their arms, to joints designated by the reference numerals 10' and 10'' respectively.
  • the joints are constituted by an internal body 11 to which the ends of the arms of the first frame 2 and of the second frame 3 are respectively pivoted.
  • the internal body 11 also forms a guiding slot 12 in which there slides a pivot 13 for connecting two bars 14 and 15 which are pivoted, at one end, to the arms of the U-shaped frames 2 and 3 respectively.
  • the connecting pivot 13 is connected to an external body 16 which is slideable with respect to the internal body and in practice moves the pivot 13, positioning the frames 2 and 3 in the closed position, with the frames arranged side by side, and in the open position, arranged at an angle to each other.
  • One of the joints is provided, at the end of the guiding slot 12, with narrower portions 12a and 12b, which in practice constitute a stop element for locking the frame in the closed position and in the open position respectively.
  • the bars 14 and 15 are also respectively provided with a notch 17 and with a tab 18 which fits in the notch 17 when the bars are arranged in the open position and are consequently divaricated, in order to act as safety element and as retainer against further rotation.
  • the particularity of the invention is constituted by the fact that one of the joints, specifically the joint 10', is provided with elastic means which are meant to push the U-shaped frames into the open position.
  • Said elastic means are provided with flexing springs, designated by the reference numeral 20, which are constituted for example by coiled springs which are located on a pivot 21 for the pivoting of the bars to the arms of the U-shaped frames 2 and 3 and in which an arm 22 of each spring acts against the internal part of a tubular element 2,3 and an arm 23 of each spring couples to the respective bar 14,15.
  • the folding frame can remain in the closed position, since the other joint, i.e., the joint 10'', has the locking element 12a,12b and the springs 20 of joint 20' are in a loaded position, preset to produce opening as soon as the lock on the other joint 10'' is released.
  • the materials used, as well as the contingent shapes and dimensions may be any according to the requirements.
