Abstract:
An energy absorbing device is for use in an energy absorbing system coupled to an object. The energy absorbing device comprises a body defining a longitudinal slot passing therethrough for receiving at least two layers of lanyard material in a tight fitting relationship. The layers are movable in opposite directions, whereby, in the event of energy absorption demand, the lanyard material is moved relative to said energy absorbing device and friction between said lanyard and said device controls the force supplied to the object. Means is provided for increasing the width of the slot following arrest of the object so as to reduce said friction and permit controlled further movement of the object. The invention provides for a two-stage descent in which after a fall, the second stage allows a controlled descent.
Abstract:
An energy absorber comprising a housing for attachment to a first body, a deformer member mounted to the housing, a strip of plastically deformable material extending in a longitudinal direction between first and second ends, an attachment member provided at, or towards, the second end of the strip for attachment to a second body, the strip being arranged with the deformer member such that when a predetermined force is applied to the attachment member, the strip is moved relative to the deformer member from a first position in which a first section of the strip extends from the first end of the strip to the deformer member, to a second position in which at least a part of the first section of the strip is plastically deformed by the deformer member, wherein the strip is arranged such that when it is in its first position, the first section of the strip is substantially flat in the longitudinal direction of the first section of the strip.
Abstract:
The invention relates to a load-securing element, comprising a base body 1, which includes a coupling section 2 for coupling a stop means A, a support section 17 provided for insertion into an opening 0, and a connecting section 16, which connects the coupling section 2 and the support section 17 to each other and maintains the distance between the same such that a slot-like holder 19 is produced at the base body 1, said holder at the upper side thereof being delimited by the coupling section 2, at the bottom side thereof by the support section 17, and at the back side thereof by the connection section 16 and otherwise being open, and wherein on the side of the connecting section 16 facing away from the holder 19 a counter bearing surface 22 is present, which is used to brace the base body 1 with respect to the edge Ro of the respective opening 0 when the support section 17 is inserted into an opening 0.
Abstract:
The present invention relates to a clamping lock for a tensioning means S, with a housing 2; 102 which comprises two cheek parts 3, 4; 103, 104 arranged at a distance from each other, a stop web 5; 105 which extends between the cheek parts 3, 4; 103, 104 and a pivot spindle 7; 107 which likewise extends between the cheek parts 3, 4; 103, 104, and with a comb element 8; 108 mounted pivotably on the pivot spindle 7; 107 of the housing 2; 102. The clamping lock according to the invention can be produced in a simple manner and at the same time has a compact, easily handleable design. This is achieved in that there is a reinforcing insert 9; 109 at least in the region of the cheek parts 3, 4; 103, 104, of the stop web 5; 105 and of the pivot spindle 7; 107 of the housing 2; 102, said reinforcing insert being surrounded by a plastic casing 10; 110 and being composed of a material which is firmer than the material of the plastic casing 10; 110.
