Child assist handrail

Abstract

A device ( 1 ) having an auxiliary handrail ( 2 ) under an existing main handrail ( 3 ) and bridge members ( 4 ) each including: a spacer member ( 5 ), an upper coupling member ( 6 ) and a lower coupling member ( 7 ). The upper coupling member includes a tension strap ( 8 ), which by means of two connection points ( 9, 10 ) is fastened to the upper coupling member, and which is arranged for clamping the upper coupling member against the main handrail. Furthermore a displacement/force-transformation-based strap-tensioning device is provided, for example a screw-tensioning member, whereby the upper coupling member is forcibly and accurately adjustably clamped against the main handrail.

1 . Device ( 1 ) comprising an auxiliary handrail ( 2 ) being attachable under an existing main handrail ( 3 ), which device furthermore comprises bridge members ( 4 ) for detachably fastening the auxiliary handrail to the main handrail;
 wherein the bridge members each comprise a spacer member ( 5 ), an upper coupling member ( 6 ) and a lower coupling member ( 7 ); wherein the spacer member is arranged for spacing apart the auxiliary handrail from the main handrail, the upper coupling members for coupling the spacer member with the main handrail and the lower coupling member for coupling the spacer member with the auxiliary handrail;   and wherein the upper coupling member comprises a tension strap ( 8 ), which is connected with the upper coupling member by two connection points ( 9 ,  10 ), and which is arranged for clamping the upper coupling member against the main handrail,   wherein furthermore a displacement/force-transformation-based strap-tensioning device ( 11 ) is provided, arranged for tightening the tension strap such, that the upper coupling member is forcibly clamped against the main handrail.   
     
     
         2 . Device according to  claim 1 , wherein the width of the tension strap is between 10 and 30 mm, and the thickness is between 1 and 2 mm. 
     
     
         3 . Device according to  claim 1 , wherein the displacement/force-transformation-based strap-tensioning device comprises a screw-tensioning member ( 12 ,  13 ). 
     
     
         4 . Device according to  claim 1 , wherein the displacement/force-transformation-based strap-tensioning device comprises a clamp member. 
     
     
         5 . Device according to  claim 1 , wherein an anti-slip layer is provided between the tension strap and the main handrail. 
     
     
         6 . Device according to  claim 1 , wherein a rear support ( 14 ) is provided for spacing apart the auxiliary handrail from a rearward wall or support body. 
     
     
         7 . Device according to  claim 1 , wherein the lower coupling member ( 7 ) is arranged for approximating the auxiliary handrail from the bottom side. 
     
     
         8 . Device according to  claim 1 , wherein the lower coupling member is arranged to substantially completely embrace the auxiliary handrail. 
     
     
         9 . Device according to  claim 1 , wherein the auxiliary handrail ( 2 ) comprises one or more auxiliary handrail segments ( 2 ′), arranged for cooperating with one or more coupling pieces ( 16 ) for joining together the auxiliary handrail segments, which jointly form a complete and continuous uninterrupted auxiliary handrail. 
     
     
         10 . Device according to  claim 9 , wherein the auxiliary handrail assembly comprises straight and/or curved auxiliary handrail segments, which jointly form a continuous uninterrupted auxiliary handrail. 
     
     
         11 . Device according to  claim 9 , wherein the auxiliary handrail and the coupling pieces are arranged such that each coupling piece can be inserted into a hollow ( 18 ) of a respective end of the auxiliary handrail, and is substantially received therein. 
     
     
         12 . Device according to  claim 1 , wherein a cross-section of the auxiliary handrail is substantially circular.
