Safety Coupling

Abstract

Safety coupling consisting of a base part and a coupling part. The base part is designed to be fitted on a building construction, such as a roof, window frame and the like. Furthermore, the safety coupling comprises a coupling part that can be connected to a facility. A facility is understood to be a ladder, scaffolding, but also a person's harness. The coupling part consists of a protruding part designed to be accommodated with a tight fit in a seat in the base part. To prevent the protruding part releasing from the seat, there is also a locking part that can be made active and inactive with a button. Preferably the construction is designed such that in the unlocked position the coupling part is completely free of the base part and also drops out of the latter. The intention is to fit a large number of base parts on buildings and other building constructions, whilst coupling to a facility by means of the coupling part is always easily possible.

1 . A safety coupling comprising a base part that can be joined to a building construction and a coupling part that can be connected to a temporary facility, wherein said coupling part can be locked to said base part such that it is detachable, wherein said base part has a seat with a peripheral rim and is provided with a locking opening in a locking wall, wherein said coupling part is provided with a protruding part and a locking member, wherein the outer periphery of said protruding part can be accepted essentially with a tight fit within said seat bearing on said peripheral rim and said protrusion can be introduced through said locking opening to engage on said locking wall. 
   
   
       2 . The safety coupling according to  claim 1 , wherein the locking wall and the peripheral wall are arranged such that these take up mutually perpendicular forces exerted on the coupling part. 
   
   
       3 . The safety coupling according to  claim 1 , wherein said seat comprises a cylindrical depression. 
   
   
       4 . The safety coupling according to  claim 1 , wherein said seat is provided with an end wall that contains said opening. 
   
   
       5 . The safety coupling according to  claim 1 , wherein said opening extends with respect to the center of said seat in two directions with identical shape. 
   
   
       6 . The safety coupling according to  claim 1 , wherein said locking wall is provided on the side facing away from said seat with enclosing means for said locking member. 
   
   
       7 . The safety coupling according to  claim 1 , wherein said locking member comprises a rotary locking tongue. 
   
   
       8 . The safety coupling according to  claim 7 , wherein said tongue extends on either side of the axis of rotation. 
   
   
       9 . The safety coupling according to  claim 1 , wherein said coupling part is provided with operating means for moving said locking member 
   
   
       10 . The safety coupling according to  claim 9 , wherein said operating member comprises a rotary knob for turning the locking member. 
   
   
       11 . The safety coupling according to  claim 9 , wherein said operating member comprises a push button for moving said locking member towards the seat. 
   
   
       12 . A building construction provided with a base part according to  claim 1 . 
   
   
       13 . A facility comprising a wall and a coupling part according to  claim 1 . 
   
   
       14 . A facility according to  claim 13 , further comprising a harness. 
   
   
       15 . The safety coupling according to  claim 10 , wherein said operating member comprises a push button for moving said locking member towards the seat. 
   
   
       16 . The safety coupling according to  claim 2 , wherein said seat comprises a cylindrical depression. 
   
   
       17 . The safety coupling according to  claim 2 , wherein said seat is provided with an end wall that contains said opening. 
   
   
       18 . The safety coupling according to  claim 3 , wherein said seat is provided with an end wall that contains said opening. 
   
   
       19 . The safety coupling according to  claim 2 , wherein said opening extends with respect to the centre of said seat in two directions with identical shape. 
   
   
       20 . The safety coupling according to  claim 3 , wherein said opening extends with respect to the centre of said seat in two directions with identical shape.
