Definitions

  • the present invention relates to ladders and more particularly to a framework which can be either folded as a stepladder or a chair or detached and stored in an enclosure or bag for decreasing a storage space.
  • a detachable ladder comprising a lower frame including two substantially trapezoidal legs, a first board interconnected tops of the legs, and one or more crosspieces interconnected the legs; and an upper frame including two side units each including a substantially trapezoidal upper element having its forward end pivotably secured to a top front end of the leg, and a lower support extended downward from the upper element, a second board interconnected bottoms of the upper elements, a third board interconnected tops of the upper elements, and one or more fourth boards interconnected intermediate portions of the upper elements;whereby pivoting the upper frame about the lower frame until the tops of the upper elements rest upon a supporting ground will convert the ladder into a chair.
  • an anti-slip shoe formed on each of the tops of the upper elements and front and rear ends of a bottom of each leg.
  • a receptacle vertically extended from the anti-slip shoe on the top of each upper element.
  • a U-shaped bar adapted to have portions of its both ends inserted into the receptacles.
  • a footrest interconnected the legs and opposing the one or more crosspieces.
  • each of the side unit further comprises a substantially inverted T-shaped member secured to the bottom of the upper element and the support such that the substantially inverted T-shaped members are adapted to form as armrests in response to forming the chair.
  • a pad having its front end pivotably secured to a rear end of the first board such that the pad is adapted to rest on the first and second boards as a seat by pivoting in response to forming the chair.
  • a pad having its rear end pivotably secured to a joining point of the upper element and the support such that the pad is adapted to rest on the first and second boards as a seat by pivoting in response to forming the chair.
  • a detachable framework in accordance with a preferred embodiment of the invention comprises a lower frame 10 including two substantially trapezoidal leg units 11 each including an inclined bar 111, a bottom bar 12, two first anti-slip shoes 16 on a bottom of the bottom bar 12, and a post 15 interconnected a top portion of the inclined bar 111 and the bottom bar 12 in which a plurality of through holes are formed in the bars 111 and 12 and the post 15 by drilling; a rectangular first board 13, and two crosspieces 14 in which a plurality of through holes are formed in the bars 111 and 12, the post 15, the first board 13, and the crosspieces 14 by drilling such that the first board 13 can be fastened on tops of the leg units 11, and the crosspieces 14 can be fastened between the inclined bars 111 by fasteners as known in the art.
  • the framework further comprises a foot rest 50 interconnected the posts 15; and an upper frame 20 including two side units 21 each including an inclined bar 211, a top bar 25 formed with the inclined bar 211, a second anti-slip shoe 27 on an end of the top bar 25, a receptacle 26 vertically extended from the second anti-slip shoe 27, and a slightly arcuate bar 22 having its top formed with the top bar 25 and an extension interconnected its intermediate point and a bottom end of the inclined bar 211; a rectangular second board 23, and a plurality of rectangular third boards 24 in which a plurality of through holes are formed in the side units 21 and the boards 23 and 24 by drilling such that the second board 23 can be fastened on the first board 13 under the extensions of the arcuate bars 22, and the third boards 24 can be fastened between the inclined bars 211 and the arcuate bars 22 by fasteners as known in the art.
  • the framework further comprises two links 30 each having both ends pivotably secured to a top of the inclined bar 111 and a bottom of the inclined bar 211.
  • a U-shaped frame element 40 has its both ends into the receptacles 26 as a guard.
  • a stepladder is formed as shown in FIG. 2.
  • two armrests 28 are formed with the chair by two frame elements attached to both sides of the stepladder after the pivotal operation described in FIGS. 3 and 4.
  • FIG. 6 a first configuration of mounting a pad as a seat of the chair formed in FIG. 4 is illustrated.
  • a rectangular pad 80 dimensioned to the size of the combined the first board 13 and the second board 23 is provided.
  • the pad 80 has one end pivotably secured to two front corners of the first board 13 and comprises two projections 81 at its two corners distal the pivots thereof.
  • two holes 29 are formed on two rear corners of the second board 23. The holes 29 are adapted to snugly receive the projections 81 after pivoting the pad 80 about 270 degrees about the pivots thereof. At this position, the pad 80 is served as a seat.
  • FIG. 7 a second configuration of mounting a pad as a seat of the chair formed in FIG. 4 is illustrated.
  • a rectangular pad 80 dimensioned to the size of the combined the first board 13 and the second board 23 is provided.
  • the pad 80 has one end pivotably secured to two rear corners of the second board 23 and comprises two projections 81 at its two corners distal the pivots thereof.
  • two holes 17 are formed on two front corners of the first board 13. The holes 17 are adapted to snugly receive the projections 81 after pivoting the pad 80 about 90 degrees about the pivots thereof. At this position, the pad 80 is served as a seat.
  • the stepladder or chair may be detached and stored in an enclosure 90 or a bag for saving occupying space when the stepladder or chair is expected to be of no use for a relatively long period of time or for transport.
