Definitions

  • the present invention aims to provide improvements to existing devices that are intended to improve the stability and anti-slip of the ladder against the roof.
  • a second objective of the user is to avoid damaging the roof sewer system often flexible or fragile material such as zinc, aluminum or plastic.
  • the model described below is composed of a superior stabilization means that will come on the roof positioning itself above the gutter and thus avoid lateral sliding during the rise of the user.
  • a second lower stabilization means will come, through two independent controls manipulated by the user, to position and tighten under the roof so as to avoid tilting the ladder back during the descent from the roof to the ladder.
  • Both of these means are dimensioned and pivoted so as to prevent the ladder from coming into contact with the gutter during use.
  • the product is composed of a frame (1) on which the upper stabilizing device (2) is fixed.
  • pivot two independent stabilizing devices (3) (3 ') symmetrical and independent operated by two controls (4) (4').
  • Four sliding and pivoting locks (5) (5 ') (5 ") (5"') integral with the frame (1) serve to connect the ladder.
  • the upper stabilizing device (2) is composed of two integral arms (6) (6 ') and a support bar (7), on which is fixed a section of flexible ribbed material (8) for protecting roofing materials and by its friction, limit the lateral movements of the device relative to the roof.
  • the device is assembled on the ladder and supported on the roof (11).
  • the four sliding and pivoting bolts (5) (5 ') (5 ") (5"') are introduced into the recesses of the bars (28) of the ladder (9).
  • the controls (4) (4 ') are raised to allow the lower stabilizers (3) (3') to pinch the roof (11) and one of its rafters (10).
  • the lower stabilizers (3) (3 ') are formed for each arm side (12) (12') pivotally relative to the frame (1) via pins (19) (19 ').
  • the arms (12) (12 ') support pieces (13) (13') integral with the arms (12) (12 ') and covered with flexible ribbed pieces (14) (14') making the system non-slip and allowing it to adapt to any form of roofing.
  • the arms (12) (12 ') are respectively driven by the controls (4) (4') through identical sets each composed of two racks (15) (15 ') similar, a flexible cylindrical pad (18), all linked to the control (4) via a riveted axis system (21) (21 ') (21 ") (21"').
  • the pawl (16) pivots about the axis (22) then pressing against the teeth of the racks (15) (15 ') by the action of a spring (23).
  • the pawl (16) in the closed position, is in contact with the two racks (15) (15 ') and, thanks to the action of the flexible cylindrical pad (18), is always in contact with a tooth of the assembly consisting of two racks (15) (15 ') allowing the device to tighten various roof thicknesses (11) without play, because the flexible cylindrical pad (18) crushes if the pawl (16) comes between two teeth racks (15) (15 ').
  • the four sliding and pivoting bolts (5) (5 ') (5 ") (5"') are assembled in pairs (5 ') (5 ") and (5) (5"'). They are connected by an elastic means (20) in tension via a hook (29) and its opposite hook.
  • These four sliding and pivoting bolts (5) (5 ') (5 ") (5"') are each composed of two tubes (26) (26 ') and a plate (27).
  • the user pulls the four sliding and pivoting bolts (5) (5 ') (5 ") (5"') successively; in doing so, it stretches the resilient means (20), rotating the sliding and pivoting bolt (5) relative to the frame (1) via the tube (26) to position itself in the axis of the hollow of the bar (28). the scale (9). It can then release the sliding and pivoting latch (5) allowing the tube (26 ') to come into the hollow of the bar (28) thanks to the tensile force generated by the elastic means (20).
  • Our invention makes it possible, thanks to the pivoting of these two pairs of sliding and pivoting bolts (5) (5 “') and (5') (5"), to be compatible between different bars depending on the type of l 'ladder.
