Abstract

Abstract The invention relates to a rotatable connection device for a driving part (1) to a driven part (2), wherein the driven part has a rotational play relative to the driving part. The driving part (1) exhibits at least two axial elastic dogs (3, 4) which end in radial teeth (5, 6) and cooperate with circular arcuate slots (8, 9) in the driven part (2), which exhibit enlarged regions (11, 13) for the passage of the radial teeth (5, 6), and with a securing part (14). This securing part (14) is provided with holes (15, 16) to receive the elastic dogs (3, 4), and a bendable strap (17, 18), which is present at each hole (15, 16), after being bent behind the dogs (3, 4), comes into abutment opposite the teeth (5, 6) at their ends. Any accidental disassembly is prevented by this means.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 139 words
Rotatable connection device for a driving part to a driven part, wherein the driven part has a rotational play relative to the driving part, characterised in that the driving part (1) exhibits at least two axial elastic dogs (3,4) which each end in a radial tooth (5,6) and each cooperate with a circular arcuate slot (8,9) in the driven part (2), which exhibits an enlarged region (11, 13) for the passage of the radial tooth (5,6) of the corresponding dog (3,4), and with a securing part (14) which is provided with holes (15, 16) to receive the ends of the elastic dogs (3,4), and the holes (15, 16) of which each exhibit a bendable strap (17, 18) which, after being bent behind the relevant dog (3,4), come into abutment opposite the tooth (5,6) at the end of said dog.
Claim 2
Dependent Claim 139 words
Rotatable connection device for a driving part to a driven part, wherein the driven part has a rotational play relative to the driving part, characterised in that the driving part (1) exhibits at least two axial elastic dogs (3,4) which each end in a radial tooth (5,6) and each cooperate with a circular arcuate slot (8,9) in the driven part (2), which exhibits an enlarged region (11, 13) for the passage of the radial tooth (5,6) of the corresponding dog (3,4), and with a securing part (14) which is provided with holes (15, 16) to receive the ends of the elastic dogs (3,4), and the holes (15, 16) of which each exhibit a bendable strap (17, 18) which, after being bent behind the relevant dog (3,4), come into abutment opposite the tooth (5,6) at the end of said dog.
