Definitions
- Such a blocker can be attached to the shoe of the right or left foot, and allows an easier ascent along a rope, in the field of mountaineering, climbing, caving, or work at height.
- the first strap surrounds the kick, and is associated with a clamping loop, while the second strap passes under the shoe being secured to the first strap opposite the second passer.
- a foot blocker of the kind mentioned is represented on the Figures 1 to 3 , and is described in detail in the document FR 2,790,968 .
- a foot blocker designated by the general reference 10, comprises a blocking element 12 associated with a pair of straps 14, 16 for attachment to a shoe.
- the blocking element 12 is provided with a C-shaped folded metal body 18, inside which is articulated a pivoting trigger 20 allowing upward movement along a rope 11.
- the trigger 20 comprises a wedging surface 22 pinned, for pressing the rope against a chute 24 when the body 18 of the blocking element 12 is biased down by the weight of the user.
- the trigger 20 pivots about the axis 26 in a clockwise direction to an open position to release the rope.
- a clamping loop 28 is associated with the first horizontal strap 14 for fixing the assembly to the foot of the user.
- the body 18 of the blocking element 12 is made of sheet metal cut, stamped and folded, and comprises two fastening devices 30, 32 arranged in the flat part to allow the passage and adjustment of the straps 14, 16.
- the first device The upper fastener 30 is provided with four substantially parallel vertical slots 34 aligned horizontally defining two loops 36, 38 for the passage of the strap 14.
- the second lower fastener 32 comprises two horizontal and parallel slots 40 forming a loop 42 for the passage of the second vertical strap 16.
- a hole 44 is formed in the body 18 to allow the attachment of a carabiner.
- a return spring 46 is mounted on the shaft 26 to bias the trigger 20 towards the closed position.
- the first loops 36, 38 extend orthogonally with respect to the second loop 42 being integrated in the flat part of the body between the trough 24 and the hinge axis 26 of the trigger 20. After its introduction, the first strap 14 extends perpendicularly with respect to the chute 24.
- This sliding defect has the effect of reducing the speed of progression, and requires more effort from the user.
- the object of the invention is to provide an improved foot blocker to limit friction and improve the sliding of the rope during the ascent.
- the foot blocker according to the invention is characterized in that the passage of the first strap in the first attachment device is inclined at a predetermined angle with respect to the guide chute of the rope, said angle being between 40.degree. ° and 75 ° so as to keep the bottom of the chute parallel to the path of the rope during the ascent.
- the angle of inclination of the first pass is close to 60 °.
- the first pass is formed by four parallel slots offset two by two in the direction of the height to define said angle of inclination.
- Such an arrangement of the first passer places the first strap in a position preventing any friction of the rope against the upper edge of the chute.
- the rope remains parallel to the bottom of the chute, and the blocker slides freely when the user raises his legs for the ascent.
- the structure of the blocking element 12 is identical to that of the figure 2 , except for the positioning of the first attachment device 30 which is inclined downwards by a predetermined angle with respect to the chute 24.
- the angle of the latter is advantageously between 40 ° and 75 ° with respect to the trough 24
- the bottom of the chute 24 remains parallel to the path of the rope 11 during the ascent ( figure 6 ).
- the blocking element 12 can thus slide freely without any friction of the rope on the top of the chute 24.
- the first attachment device 30 is formed by four parallel slots 34 forming two loops 36, 38 offset in pairs in the direction of the height to define said angle of inclination.
- the first strap 14 thus passes through the two loops 36, 38) in a direction inclined relative to the horizontal.
- the second attachment device 32 is identical to that of the figure 2 and is formed by two parallel and superposed slots 40.
