Abstract
A pull-out guide assembly for drawers, having on both sides of the drawer a support rail on the carcass and a pull-out rail on the drawer. The load of the drawer is transmitted between the rails by rollers that are borne in running carriages. The running carriages may be moved between a front end position and a rear end position in a differential manner. Locking means are provided for the running carriages and, in the event of a deviation from the differential running between the rails, they lock the running carriage on one of the rails at predetermined points between the two end positions. This locking is releasable by the movement of the rails with respect to one another.
Claims11
A pull-out guide assembly for a drawer, comprising:
- a support rail to be mounted on a carcass;
- a pull-out rail to be mounted on the drawer;
- and
- a running carriage mounted between said support rail and said pull-out rail and operable to move between a front end position and a rear end position in a differential manner, said running carriage including:
- rollers for transmitting a load of the drawer between said support rail and said pull-out rail;
- and
- a locking device operable to lock said running carriage to said pull-out rail at a first predetermined point located between said front end position and said rear end position, and operable to unlock said running carriage from said pull-out rail at a second predetermined point located between said front end position and said rear end position due to relative movement between said support rail and said pull-out rail;
- wherein said support rail, said pull-out rail, and said running carriage are arranged and interconnected such that, if said running carriage is locked to said pull-out rail at said first predetermined point by said locking device while moving toward one of said front end position and said rear end position, said running carriage is operable to continue moving toward said one of said front end position and said rear end position in the differential manner after being unlocked by said locking device at said second predetermined point;
- and wherein said locking device comprises a rocker tiltably mounted on said running carriage, said rocker having two stop faces shaped to abut against a stop on each of said support rail and pull-out rail.
A pull-out guide assembly for a drawer, comprising:
- a pair of support rails to be mounted on opposite sides of a carcass;
- a pair of pull-out rails to be mounted on opposite sides of the drawer;
- and
- running carriages mounted between said support rails and said pull-out rails and operable to move between a front end position and a rear end position in a differential manner, each of said running carriages including:
- rollers for transmitting a load of the drawer between said support rails and said pull-out rails;
- and
- a locking device operable to lock said running carriage to a respective one of said pull-out rails at a first predetermined point located between said front end position and said rear end position, and operable to unlock said running carriage from said respective one of said pull-out rails at a second predetermined point located between said front end position and said rear end position due to relative movement between said support rails and said pull-out rails;
- wherein said support rails, said pull-out rails, and said running carriages are arranged and interconnected such that, if one of said running carriages is locked to a respective one of said pull-out rails at said first predetermined point by said locking device while moving toward one of said front end position and said rear end position, said running carriage is operable to continue moving toward said one of said front end position and said rear end position in the differential manner after being unlocked by said locking device at said second predetermined point;
- and wherein said locking device comprises a rocker tiltably mounted on said running carriage, said rocker having two stop faces shaped to abut against a stop on each of said respective support rails and pull-out rails.
