Definitions

  • the object of the invention is a connector for articulated and fixed components of a structural element, and in particular for attic stairs.
  • Attic stairs where a hatch is suspended from the first segment of stairs using at least two pairs of connectors, which together with the first segment of the stairs and the hatch constitute a four-bar linkage system has been disclosed in PL228252B1 .
  • the connectors used to suspend the hatch are attached to it using hook brackets, and each has a bearing seat for an extension seated in the connector used to suspend the hatch.
  • the assembly opening for this seat is covered by an insert which includes a bearing fill surface and is snap mounted in the hook connector body.
  • the hook connector bearing seat has a pass-through opening on both sides, and the extension of the connector used to suspend the hatch terminates with a flange with a larger diameter than the diameter of the seat.
  • the invention aims to prepare a connector for components of a structural element which will enable these components to be detached simply and quickly.
  • the connector construction also makes it possible to lock the connection of the components against unintentional detachment and this is achieved using only the connector without applying additional locking elements.
  • the essence of the invention is a connector comprising a bracket and a flat bar terminating with a latching element, preferably a hook, wherein the connector is an element connecting an articulated component with a fixed component of a structural element.
  • the connector bracket is mounted in a hole in the flat panel of the articulated component and comprises a base with a plate with at least one latching foot. The lower gap for the hole edge in the flat panel is located between the latching foot and the plate.
  • the bracket base is fixed in the hole using the lock.
  • the lock includes a locking foot which fills the hole in the flat panel which already holds one of the base latching feet. Once the lock is inserted into the hole, the lock and the base are connected by at least one coupling or glue.
  • the bracket also includes a coaxial opening in the base and the lock wherein the pin used to suspend the flat bar hook is inserted into.
  • the bracket is made out of plastic.
  • the bracket also includes a gap, running perpendicular to the pin insertion direction, where the flat bar hook is located.
  • the other end of the flat bar terminating with a hook is mounted to the fixed component in a manner making it possible to move the articulated component together with the flat bar relative to the fixed component.
  • the articulated component When the articulated component is in an essentially vertical position relative to the fixed component, it may be lifted up slightly and the pin, seated earlier in the hook socket, is guided along the inner surface of the hook in the direction of the fixed component.
  • the hook travels along the bracket gap, until the articulated component detaches from the fixed component. In a position where the articulated component is slightly tilted, the hook cannot travel in the bracket gap as it is locked by the stop face of the bracket base, and the articulated component remains attached to the fixed component.
  • the connector prevents unintentional detachment of the articulated component from the fixed component.
  • the components may be locked by tilting the articulated component relative to the fixed component whilst connecting the flat bar to the bracket, whereas the components may be unlocked by aligning the articulated element essentially vertically relative to the fixed component, wherein a tilted position of the articulated component is a natural use position for a structural element.
  • Closing hatch 2 includes at least two brackets comprising a base 3 and lock 4, which are seated in hole 21 of closing hatch 2.
  • the base includes plate 31 with two latching feet 32 with lower gap 33 for hole 21 edge in closing hatch 2 located between plate 31 and each latching foot 32.
  • Lock 4 includes locking foot 43 which fills hole 21 in closing hatch 2 which already holds one of the latching feet 32, locking bracket base 3 in place in the bracket locked position.
  • Both base 3 and lock 4 include shaped faces, which ensure lock 4 is guided during assembly into the correct position in base 3.
  • Lock 4 also includes couplings 41, 42, and base 3 includes coupling 34. During lock insertion into the hole the couplings flex, and in base 3 locked position they are flush with appropriate base 3 and lock 4 surfaces fixing the bracket in closing hatch 2 hole.
  • On an inside wall of a frame element of attic stairs box 1 is hinge hanger 5 on which ladder segments 61, 62, 63 are suspended.
  • Flat bar 7 terminating with hook 71, with pin 8 seated in a coaxial holes of base 3 and lock 4 in its seat is suspended from the same hanger 5.
  • Flat bar 7 terminating with hook 71, is in gap 9 of the bracket, wherein pin 8 is perpendicular to the longitudinal direction of said gap 9.
  • hook 71 and the bracket makes it possible to detach closing hatch 2 from the attic stairs or to lock it in the attic stairs' use position.
  • Closing hatch 2 is in an essentially vertical position relative to box 1 of the attic stairs, when closing hatch 2 and lower flat bar 10 are not attached. Then closing hatch 2 may be slightly lifted up, and pin 8 is guided along hook 71 inner surface towards attic stairs box 1. At the same time hook 71 travels along bracket gap 9, until closing hatch 2 detaches from the attic stairs.
  • closing hatch 2 In the attic stairs' use position, closing hatch 2 assumes its use position, that is a position where it is tilted relative to attic stairs box 1.
  • the closing hatch in a tilted position means it is attached by lower flat bars 10. In such closing hatch 2 position, hook 7 cannot travel in bracket gap 9 as it is locked by stop face 35 of bracket base 3 plate 31, and closing hatch 2 remains attached to the attic stairs.
