Embodiment Construction

[0044] Figure 1A and 1B According to the assembled structure ( Figure 1A ) and by exploded view ( Figure 1B ) shows the rotary operator assembly 1 and a part of the switch 2. The rotary operator assembly 1 (or simply "assembly 1") includes a handle part 4 , a shaft part 6 , an operator body part 8 and a mounting nut 10 . A compression spring 12 is arranged between the handle part 4 and the shaft part 6 .

[0045] After forming the assembled structure of substantially closed assembly 1 ( Figure 1A ), the handle 4 is configured to receive and substantially cover the spring 12, a portion of the shaft member 6 and a portion of the operator body member 8.

[0046] The switch 2 includes a rotary shaft 14 and a housing 16 .

[0047] The shaft 14 is rotatable about an axis of rotation A relative to the housing 16 . The handle part 4 and the shaft part 6 are substantially rotatable about an axis of rotation A relative to the operator body part 8 (see below).

[0048] The op...

Abstract

A rotary operator assembly comprises a grip member, a spindle member, and an operator body member. The spindle member is attached to the operator body member, being rotatable with respect to the operator body member about an operative axis of rotation. The grip member is movably coupled to the spindle member and the operator body member and is translatable between a first translational position and a second translational position with respect to the operator body member. The grip member and the operator body member comprise cooperating means for blocking rotation of the grip member with respect to the operator body member about the operative axis of rotation in the first position and for allowing rotation of the grip member with respect to the operator body member about the operative axis of rotation in the second position from a first angular position to a second angular position. The grip member is configured to operably couple with the spindle member in at least the second translational position, and the grip member comprises at least one portion cooperating with at least one portion of the spindle member for preventing translation of the grip member between the first translational position and the second translational position in the first angular position.

Description

technical field [0001] The present invention relates to the field of rotary operators and in particular to rotary operators including security features to prevent unauthorized operation. Background technique [0002] Rotary operating devices are known, as are rotary operators for operating the rotary operating devices. Examples are rotary switches and rotary valves, which include manually operable rotary operators, such as handle knobs, knobs or levers. A special type of rotary operator is formed by the safety rotary operator, wherein, by locking the rotary operator in a specific position (safety position) ) to prevent unauthorized operation of the rotary operating device. [0003] However, if the rotary operator is locked in a "safe" position, and the operating part of the rotary operator is not in the corresponding desired state, a dangerous situation will arise. For example, in some In a rotary electrical switch with rotary electrical contacts, the contacts have been w...
