Locking mechanism according to claim 1, wherein after a second locking portion, the catch pin transitions towards the front end in the insertion direction, via the stepped shoulder, into a portion formed with a tapered diameter by comparison with the first locking portion and which tapers further, at least over part of the length thereof, towards the free end of the catch pin. 3. Locking mechanism according to claim 1, wherein the catch pin is positioned on a pivotable locking and release lever, and can be adjusted about a pivot axis against a force of a spring means. 4. Locking mechanism according to claim 1, wherein the angular range within which the table top can be pivoted, in a manner delimited by stops, before the final release of the locking and release means is less than ±20°. 5. Locking mechanism according to claim 1, wherein the angular range within which the table top can be pivoted, in a manner delimited by stops, before the final release of the locking and release means is less than ±2°. 6. Locking mechanism for locking a table top in a work position thereof and for releasing the table top in order to pivot it into a storage position, the locking mechanism comprising: a table top support securable to an underside of the table top;a bracing head attachable to a support column, wherein the locking mechanism acts between the table top support and the bracing head;an actuation means cooperable with the table top support and having a locking and release means; anda retaining means cooperable with the bracing head wherein when locked, the locking and release means cooperates with the retaining means such that the table top is held in the work position thereof without play, andwherein when the locking mechanism is released, the locking and release means is adjusted or pivoted relative to the retaining means such that the table top can be pivoted from the work position into the storage position thereof,the locking mechanism defining at least one intermediate position, in which the table top is pivotable only through a restricted angular range of at least a few degrees delimited by stops,wherein the locking and release means comprises a catch pin which cooperates with a catch recess, the size of which is delimited by a delimitation,wherein the catch pin comprises a first locking portion, which in the locked position cooperates with the delimitation of the catch recess, without play, and wherein a tapering portion is attached to the first locking portion towards a front end of the first locking portion in an insertion direction, play being established by a distance between the tapered portion and the delimitation, defining the angular range within which the table top can be pivoted. 7. Locking mechanism for locking a table top in a work position thereof and for releasing the table top in order to pivot it into a storage position, the locking mechanism comprising: a table top support securable to an underside of the table top;a bracing head attachable to a support column, wherein the locking mechanism acts between the table top support and the bracing head;an actuation means cooperable with the table top support and having a locking and release means; anda retaining means cooperable with the bracing head wherein when locked, the locking and release means cooperates with the retaining means such that the table top is held in the work position thereof without play, andwherein when the locking mechanism is released, the locking and release means is adjusted or pivoted relative to the retaining means such that the table top can be pivoted from the work position into the storage position thereof,the locking mechanism defining at least one intermediate position, in which the table top is pivotable only through a restricted angular range of at least a few degrees delimited by stops,wherein the locking and release means comprises a catch pin which cooperates with a catch recess, the size of which is delimited by a delimitation,wherein the catch pin, extending from a second locking portion, transitions into a portion which tapers increasingly towards the front end of the catch pin and to which a further portion of a constant diameter is attached. 8. Locking mechanism for locking a table top in a work position thereof and for releasing the table top in order to pivot it into a storage position, the locking mechanism comprising: a table top support securable to an underside of the table top;a bracing head attachable to a support column, wherein the locking mechanism acts between the table top support and the bracing head;an actuation means cooperable with the table top support and having a locking and release means; anda retaining means cooperable with the bracing head wherein when locked, the locking and release means cooperates with the retaining means such that the table top is held in the work position thereof without play, andwherein when the locking mechanism is released, the locking and release means is adjusted or pivoted relative to the retaining means such that the table top can be pivoted from the work position into the storage position thereof,the locking mechanism defining at least one intermediate position, in which the table top is pivotable only through a restricted angular range of at least a few degrees delimited by stops,wherein in an insertion direction, a catch pin is divided up into various portions, which comprise one or more steps and/or one or more portions which taper towards an end and/or one or more portions of a constant external dimension. 9. Locking mechanism for locking a table top in a work position thereof and for releasing the table top in order to pivot it into a storage position, the locking mechanism comprising: a table top support securable to an underside of the table top;a bracing head attachable to a support column, wherein the locking mechanism acts between the table top support and the bracing head;an actuation means cooperable with the table top support and having a locking and release means; anda retaining means cooperable with the bracing head wherein when locked, the locking and release means cooperates with the retaining means such that the table top is held in the work position thereof without play, andwherein when the locking mechanism is released, the locking and release means is adjusted or pivoted relative to the retaining means such that the table top can be pivoted from the work position into the storage position thereof,the locking mechanism defining at least one intermediate position, in which the table top is pivotable only through a restricted angular range of at least a few degrees delimited by stops,wherein the catch pin is positioned on a pivotable locking and release lever, and can be adjusted about a pivot axis against a force of a spring means,wherein the locking and release lever cooperates with a force transmission lever, to which it is connected about a pivot axis, a transmission means, which can be disengaged via a disengagement mechanism, being positioned on the force transmission lever. 10.
