1. A pull-out shelf for mounting on rack uprights (1), comprising:
- two brackets (4) projecting from the uprights or from supports mounted thereon, at least one rail (7) mounted on each bracket so as to be capable of being pulled out, and a shelf plane (8-12), supported by the rails, for articles which are to be placed on the shelf, said shelf comprising at least one releasable locking member which, when an associated operating member (18) is actuated manually, releases the rails (7), so that the rails can be pulled out and pushed in, and, in the unactuated state, locks the rails relative to the brackets (4), wherein, when the operating member is unactuated, said locking member locks the rails under the action of a spring force, in that said manual actuation of the operating member occurs counter to the action of said spring force, so that releasing said operating member results in instantaneous locking of the rails and thus the shelf in the current position so as to allow locking of the shelf in any position between an inner and an outer end position, wherein said locking member follows the movements of the shelf and comprises a friction body (24) projecting between engagement surfaces of one of said two brackets (4) of the shelf, wherein the friction body (24) has a non-circular cross section, and said operating member (18) is adapted so as, when actuated, to bring about a rotation of the friction body from a locking position, in which the friction body is in friction engagement with said engagement surfaces, into a free position, in which it can be displaced relative to said engagement surfaces.

Abstract
Pull-out shelf for mounting on rack uprights, comprising two brackets (4) projecting from the uprights. Each bracket bears a pullout rail (7) and a shelf plane (8-12) or equivalent, supported by the rails, for articles which are to be placed on the shelf. The shelf comprises at least one releasable locking member which, when an associated operating member (18) is acuated manaully, releases the pull-out rails (7), so that these can be pulled out and pushed in, and, in the unactuated state, locks the rails relative to the brackets (4). The locking members are adapted so as, when the operating member is unactuated, to lock the rails under the action of a spring force, the manual actuation of the operating member taking place counter to the action of this spring force. Releasing the operating member then results in instantaneous locking of the rails and thus the shelf in the current position, which allows stepless locking of the shelf in optional positions between an inner and an outer end position.

-
two brackets (4) projecting from the uprights or from supports mounted thereon, at least one rail (7) mounted on each bracket so as to be capable of being pulled out, a shelf plane (8-12), supported by the rails, for articles which are to be placed on the shelf, said shelf comprising two releasable locking member which, when an associated operating member (18) is actuated manually, releases the rails (7), so that the rails can be pulled out and pushed in, and, in the unactuated state, locks the rails relative to the brackets (4), wherein, when the operating member is unactuated, said locking members lock the rails under the action of a spring force, in that said manual actuation of the operating member occurs counter to the action of said spring force, so that releasing said operating member results in instantaneous locking of the rails and thus the shelf in the current position so as to allow locking of the shelf in any position between an inner and an outer end position, and a rotatable friction body (24) arranged between engagement surfaces of each of said brackets (4), wherein said friction bodies (24) consist of the end portion of a bar (22) extending between the brackets (4), in that the bar follows the displacement movements of the shelf, and in that the bar can by rotated by means of said operating member (18).
