Abstract

To order to positively lock or arrest an adjusted position at a mechanical device, for instance the elevation position at a firing device, with negligible play, wherein there is fixed the position set by a hand wheel serving for adjustment of the elevation position of the firing device, there is provided a locking or arresting apparatus comprising a clamping device arranged at a stationary part or housing of the firing device. The clamping device comprises two jaw members. By means of the clamping device, following setting of the desired position, such as the elevation position of the firing device, a ring member fixedly connected with the rotatably mounted hand wheel can be clamped between both clamping jaw members by the clamping device. In this way, the ring member can be positively arrested or fixed in position. The locking or arresting apparatus has many fields of application for all types of mechanical devices of different construction.

Dependent claims

A locking apparatus for securing an adjusted position at a device, comprising:

housing means provided for said device;
an adjustment mechanism having an axis of rotation;
said adjustment mechanism comprising a substantially cylindrical-shaped ring member arranged substantially concentrically with respect to the axis of rotation of the adjustment mechanism;
a clamping device cooperating with said substantially cylindrical-shaped ring member;
said clamping device comprising a pair of clamping jaw members;
said clamping jaw member being capable of assuming a clamping position, in which said substantially cylindrical-shaped ring member is clamped between the pair of clamping jaw members, and a released position, in which said substantially cylindrical-shaped ring member is released from both clamping jaw members of said pair of clamping jaw members;
said clamping device containing a displaceable member which is axially displaceable relative to and in said housing means and radially displaceable with respect to said substantially cylindrical-shaped ring member;
said displaceable member containing a coupling shaft section for coupling said displaceable member via a threaded bore in a clamping jaw member of said pair of clamping jaw members to said pair of clamping jaw members for displacing both said clamping jaw members of said pair of clamping jaw members in a self-positioning manner between said clamping position and said released position relative to said substantially cylindrical-shaped ring member;
and
actuation means for displacing said displaceable member axially relative to and in said housing means and radially with respect to said substantially cylindrical-shaped ring member.

said housing means comprising a recess;
an insert member arranged in said recess of said housing means;
said clamping device containing said two clamping jaw members being arranged at least partially in said recess;
said adjustment mechanism comprising a hand wheel;
said hand wheel supporting said substantially cylindrical-shaped ring member;
and
said insert member being arranged within said recess of said housing means and extending toward said substantially cylindrical-shaped ring member in radially spaced relationship from said axis of rotation of the adjustment mechanism.
