ensioned against the gear-shifting elements and engages positively with guide surfaces on the individual gear-shifting elements. The gear-shifting element guide surface can be advantageously designed so that a movement of one of the gear-shifting elements from the neutral position into the gear-engaged position or into one such position causes at least one element of the locking element arrangement to move in such a way that the locking element arrangement is tensioned more strongly against the other or all the other gear-shifting elements. A locking device of this type of particularly simple mechanical design has a spring-loaded plunger arrangement or ball arrangement, which is tensioned between two shaft elements and which engages positively in a recess in the guide surface of the gear-shifting element in question when this element is in the neutral position.
The locking device can have an even simpler mechanical design when formed as one rigid, inelastic locking element, not pretensioned in any way, or based on several such elements. It is proposed in this respect but also in general that the locking device have at least one locking element which is movably supported and dimensioned in such a way that, when the gear-shifting elements are in the neutral position, it is or can be brought into retaining engagement with at least one of the gear-shifting elements, and that any one of the gear-shifting elements can be moved out of the neutral position into the gear-engaged position or into one such position, where, when any one of the gear-shifting elements moves out of the neutral position into the gear-engaged position or into one such position, the gear-shifting element which moves out of the neutral position brings the locking element into retaining engagement with the other gear-shifting element or with all the other gear-shifting elements. The locking element can be, for example, a rigid plunger or pin with no moving parts, or a rigid disk with no moving parts.
It is proposed by way of elaboration that the retaining engagement is a positive engagement between an engaging section, such as an engaging end, of the locking element and an engaging section, such as a recess, in a surface of the associated gear-shifting element.
We are thinking here, for example, that, when the gear-shifting elements are in the neutral position, the locking element (e.g., the previously mentioned pin or plunger) can move in exactly one direction, especially in linear fashion, between a retaining engagement with
ensioned against the gear - shifting elements and engages positively with template surface on the individual gear - shifting elements. The gearing - shifting element guide open can be advantageously designed so that a motion of one of the gear - shifting element from the neutral position into the gearing - engaged position or into one such position causes at least one element of the locking element agreement to move in such a way that the locking chemical element arrangement is tensioned more strongly against the other or all the early gear - stir elements. A locking device of this type of peculiarly simple mechanical design has a spring - loaded plunger musical arrangement or ball arrangement, which is tensioned between two shaft elements and which engages positively in a recess in the guide surface of the gear - shifting component in question when this element is in the achromatic position. 
 The locking device can have an even simpler mechanical invention when formed as one rigid, inelastic locking element, not pretensioned in any way, or free-base on several such elements. It is proposed in this respect but also in general that the lock device have at least one locking element which is movably supported and dimensioned in such a way that, when the gearing - shift elements are in the neutral position, it is or can be institute into retaining engagement with at least one of the gear - shift elements, and that any one of the gear - shifting elements can be move out of the neutral place into the gear - engaged military position or into one such position, where, when any one of the gearing - shifting elements moves out of the neutral placement into the gear - engaged situation or into one such position, the gearing - shifting element which moves out of the inert position brings the locking element into retaining battle with the other gear - switch element or with all the other gear - shifting elements. The locking chemical element can be, for example, a rigid plunger or pin with no moving parts, or a rigid phonograph record with no move parts. 
 It is proposed by way of elaboration that the retaining engagement is a convinced engagement between an engaging section, such as an engaging end, of the lock chemical element and an engaging section, such as a recess, in a surface of the associated gearing - shifting element. 
 We are thinking here, for example, that, when the gear - shifting elements are in the impersonal position, the locking element (e.g., the previously mentioned pin or diver) can move in exactly one direction, especially in linear fashion, between a retaining engagement with

A locking device of this type of simple mechanical design has a spring-loaded plunger arrangement ball arrangement, which is between two shaft elements and engages in a in guide of the gear-shifting in question when this element is in the neutral position.
