Abstract
Abstract A holding device and driving band for folding doors particularly of furniture, closets and other structure. A door wing journaled to swing about a vertical axis has a lever carried pivotally along one side thereof. The lever has more than one arm portion optionally resiliently movable in longitudinal, bellcrank and triangular manner with respect to each other. Up to two pin members are carried by the arm portion arrangement and these pin members cooperate with a fixed guide track. A resilient means is optionally provided between an end stop of the guide track and one of the pin members.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
197 words
A driving band for folding doors particularly of structure having at least one freely movable wing journaled along a door folding axis and having a guide track for the structure, comprising: lever means having a first projection engaging the track and journaled at one end to the door wing, a second projection likewise engaging the track and provided in end stop position at a constant spacing from said first projection on said lever means, pivot means carried by said lever means in a location intermediate said first projection and the door wing journaled locations thereof, a further lever arm member journaled at one end to said pivot means and journaled at an opposite end to said second projection, said pivot means together with said first and second projections defining collectively a triangular relationship for end stoP position between said lever means and said lever arm member relative to each other, and spring means having one of opposite ends thereof secured to said second projection so that against bias of said spring means there is a dead center pivotal relationship that exists between said lever means and said further lever arm member for reaching end stop position thereof.
Claim 2
Dependent Claim
197 words
A driving band for folding doors particularly of structure having at least one freely movable wing journaled along a door folding axis and having a guide track for the structure, comprising: lever means having a first projection engaging the track and journaled at one end to the door wing, a second projection likewise engaging the track and provided in end stop position at a constant spacing from said first projection on said lever means, pivot means carried by said lever means in a location intermediate said first projection and the door wing journaled locations thereof, a further lever arm member journaled at one end to said pivot means and journaled at an opposite end to said second projection, said pivot means together with said first and second projections defining collectively a triangular relationship for end stoP position between said lever means and said lever arm member relative to each other, and spring means having one of opposite ends thereof secured to said second projection so that against bias of said spring means there is a dead center pivotal relationship that exists between said lever means and said further lever arm member for reaching end stop position thereof.
Claim 3
Dependent Claim
107 words
A driving band for folding doors particularly of structure having at least one freely movable wing journaled along a door folding axis comprising: a guide track for the structure, a lever engaging said track and end journaled with respect to said wing in a location spaced from said door folding axis, a turning point adjacent to said track engaging end thereof and located intermediate opposite ends of said lever, a right angle crank having one end pivotally journaled to said turning point and an opposite end journaled to said track, and spring means resiliently biasing track ends of said lever and crank with respect to each other.
Claim 4
Dependent Claim
107 words
A driving band for folding doors particularly of structure having at least one freely movable wing journaled along a door folding axis comprising: a guide track for the structure, a lever engaging said track and end journaled with respect to said wing in a location spaced from said door folding axis, a turning point adjacent to said track engaging end thereof and located intermediate opposite ends of said lever, a right angle crank having one end pivotally journaled to said turning point and an opposite end journaled to said track, and spring means resiliently biasing track ends of said lever and crank with respect to each other.
Claim 5
Dependent Claim
30 words
A driving band according to claim 2, in which identical pin members engage said guide track and are carried respectively by track ends of both said lever and said crank.
Claim 6
Dependent Claim
22 words
A driving band according to claim 2, in which means forming a turning axis of said lever is recessed into said wing.
Claim 7
Dependent Claim
103 words
A driving band for folding doors particularly of structure having at least one freely movable wing journaled along a door folding axis and having a guide track for the structure, comprising: a lever engaging the track and journaled at one end to the door wing, a pivot means carried by said lever in a location intermediate opposite ends of said lever, a further single arm lever member journaled to said pivot means, a stop arm linked to track ends of said lever and said lever member, and spring means resiliently biasing said lever member and said stop arm with respect to said lever.
Claim 8
Dependent Claim
103 words
A driving band for folding doors particularly of structure having at least one freely movable wing journaled along a door folding axis and having a guide track for the structure, comprising: a lever engaging the track and journaled at one end to the door wing, a pivot means carried by said lever in a location intermediate opposite ends of said lever, a further single arm lever member journaled to said pivot means, a stop arm linked to track ends of said lever and said lever member, and spring means resiliently biasing said lever member and said stop arm with respect to said lever.
Claim 9
Dependent Claim
28 words
A driving band according to claim 5, in which identical projections engage the track shared thereby and are carried respectively by said lever member and said stop arm.
Claim 10
Dependent Claim
26 words
A driving band according to claim 5, in which a spring is effective upon a pivot axis for journaling said lever with respect to said swing.
Claim 11
Dependent Claim
26 words
A driving band according to claim 7, in which said pivot axis for journaling said lever is formed by a journaling body recessed into said wing.
