  • Patent number: 10370058
    Abstract: The present invention relates to a removable insert system (R) for a telescopic fork leg (1) of a bicycle, said telescopic fork leg (1) comprising outer and inner legs (1b, a), wherein said removable insert system comprises a piston and piston rod arrangement (6, 8) comprising a piston rod (8) arranged at least partly within a first tube (7), said removable insert system (R)being removably arranged within at least one of said inner legs (1a) such that, when being mounted in said inner leg, the removable insert system is adapted to form a damping system (D) with said inner leg, and wherein said inner leg and said first tube are both acted upon by a flow of medium created by compression and expansion movements of the fork legs, said damping system further comprising medium flow passages (C1, C2) that are parallel in relation to each other, and that run between the upper and lower sides of said piston (6)The invention also relates to a damping cartridge kit (DC) for upgrading a telescopic fork leg of a bicycle,

  • Patent number: 8629743
    Abstract: A latching apparatus for an operating mechanism for an electrical switching apparatus includes a first member movable between a first position and a second position, in the first position the first member adapted to lock a drive member of the operating mechanism and a force of the drive member applied to the first member, and in the second position the first member is adapted to release the drive member from the locked position. Guiding means guides the movement of the first member. A trip member is movable between a third position and a fourth position, in the third position the trip member adapted to lock the first member, and in the fourth position the trip member is adapted to release the first member. The guiding means are adapted to guide at least a first portion of the first member in a first direction toward a counter roller.
