Claim 3

The system as defined in claim 1, wherein at least one further branch guide rail extends at an angle from a side opposite to said one side of said main guide rail and wherein each of said retainers has a further upstanding guided member disposed on a side opposite to said one side of said vertical swivel axis.

Claim 4

The system as defined in claim 1, wherein each of said guide means comprises at least one substantially L-shaped plate-like member of a predetermined thickness.

Claim 5

The system as defined in claim 1, wherein each of said guide means is formed by a pair of roller one of which is contacted by said inner side portion of said pre-selected one of said guided members and the other of which is contacted by said front portion of said pre-selected one of said guided members.

Claim 6

The system as defined in claim 1, wherein said guided members are in the form of rollers.

Claim 7

The system as defined in claim 1, wherein each of said retainers has at its lower end a runner guide extending longitudinally in a direction of advance of the retainer, opposite sides of said runner guide facing opposite edges respectively of said longitudinally extending open passageway in said main and branch guide rails.

Claim 8

A guiding system for movable suspended partition walls comprising at least one hollow main guide rail, at least two spaced, hollow branch guide rails each extending at an angle and to one side of said main guide rail, said main and branch guide rails defining at least two directional change points therebetween, each of said main and branch guide rails having a longitudinally extending open passageway on its underside, a plurality of retainers disposed within said main and branch guide rails so as to be freely movable along said open passageway, and suspending therefrom a plurality of partition walls each of which is relatively movable about a vertical suspension bar which extends upwards from each of said partition walls into said main and branch guide rails and is rotatably supported by a relevant one of said retainers, means to select directions of movement of said retainers so that selected ones only among said retainers can move from said main guide rail into one of said branch guide rails and vice versa at each of said directional change points, said means having a plurality of guide means, one of which is selectively disposed at each of said directional change points, a plurality of upstanding guided members fixedly mounted on said retainers, in such a manner that a selected one of said guided members is immovably disposed in operation and located on one side of a vertical swivel axis of each of said retainers, each of said guided members having a predetermined height that enables each of said guided members to contact only a pre-selected one of said guide means at a pre-selected one of said directional change points and freely pass underneath any other preceding one of said guide means at any preceding one of said directional change points, each of said guide means having a first guiding part fixedly mounted on said guide means which is contacted by an inner side portion, a portion adjacent to a center line of said open passageway, of a preselected one of said guided members, and a second guiding part fixedly mounted on said guide means which is contacted by a front portion, as viewed in a direction of advance of said retainers, of said pre-selected one of said guided members, when said pre-selected one of said guided members comes into contact with a cooperating one of said guide means, a level of contact between said guided members and said guide means at a first one of said directional change points is higher than that at a second one of said directional change points, each of said retainers has at its lower end a runner guide extending longitudinally in a direction of advance of the retainer, opposite sides of said runner guide facing opposite edges respectively of said longitudinally extending open passageway in said main and branch guide rails, and said open passageway is defined between a pair of upturned flanges of said main and branch guide rails, said upturned flanges being of lesser height in each region of said directional change points and lower walls at front and rear ends of said runner guide being so shaped as to be able to pass over said edges of said open passageway at said directional change points.

Claim 9

A guiding system for movable suspended partition walls comprising at least one hollow main guide rail, at least two spaced, hollow branch guide rails each extending at an angle and to one side of said main guide rail, said main and branch guide rails defining at least two directional change points therebetween, each of said main and branch guide rails having a longitudinally extending open passageway on its underside, a plurality of retainers disposed within said main and branch guide rails so as to be freely movable along said open passageway, and suspending therefrom a plurality of partition walls each of which is relatively movable about a vertical suspension bar which extends upwards from each of said partition walls into said main and branch guide rails and is rotatably supported by a relevant one of said retainers, means to select directions of movement of said retainers so that selected ones only among said retainers can move from said main guide rail into one of said branch guide rails and vice versa at each of said directional change points, said means having a plurality of guide means, one of which is selectively disposed at each of said directional change points, a plurality of upstanding guided members fixedly mounted on said retainers, in such a manner that a selected one of said guided members is immovably disposed in operation and located on one side of a vertical swivel axis of each of said retainers, each of said guided members having a predetermined height that enables each of said guided members to contact only a pre-selected one of said guide means at a pre-selected one of said directional change points and freely pass underneath any other preceding one of said guide means at any preceding one of said directional change points, each of said guide means having a first guiding part fixedly mounted on said guide means which is contacted by an inner side portion, a portion adjacent to a center line of said open passageway, of a preselected one of said guided members, and a second guiding part fixedly mounted on said guide means which is contacted by a front portion, as viewed in a direction of advance of said retainers, of said pre-selected one of said guided members, when said pre-selected one of said guided members comes into contact with a cooperating one of said guide means, a level of contact between said guided members and said guide means at a first one of said directional change points is higher than that at a second one of said directional change points, each of said retainers has at its lower end a runner guide extending longitudinally in a direction of advance of the retainer, opposite sides of said runner guide facing opposite edges respectively of said longitudinally extending open passageway in said main and branch guide rails, and said open passageway is defined between a pair of upturned flanges of said main and branch guide rails, said upturned flanges being of lesser height in each region of said directional change points and lower walls at front and rear ends of said runner guide being so shaped as to be able to pass over said edges of said open passageway at said directional change points.
