Abstract
The disclosure is of a frame member rotatable about a vertical axis, with means in the rotative system for locking the frame member in 180.degree. positions and also for permitting relative movement relative to the rotative means whereby a frame member may be integrated with respect to a stationary wall opening. The rotatable means is a circular race with indentations at 180.degree. positions.
Claims4
A system for mounting a rotatable frame member with respect to a vertical wall member comprising:
- an elongated, rectangularly shaped frame member having vertical side walls and horizontal top and bottom walls where the side edges of said walls define at least one forward edge surface lying in a vertical plane,
- a vertical axis extending through said top and bottom walls and being parallel to the vertical plane defined by said forward edge surface,
- a forward vertical wall member,
- upper and lower horizontal support members attached to said forward vertical wall member,
- first plate members respectively attached to said upper support member and said top wall of said frame member, and second plate members respectively attached to said lower support member and said bottom wall of said frame members,
- rotational means on each of said plate members aligned with respect to said vertical axis for permitting rotation of said frame member for at least 180.degree. about said vertical axis while providing vertical stability for said frame member,
- said rotational means having means for locking said plate members relative to one another at 180.degree. positions, said locking means being operative upon horizontal movement of said plate members on said frame member relative to the plate members on said support members.

A system for mounting a rotatable frame member with respect to a vertical wall member comprising:
- an elongated, rectangularly shaped frame member having vertical side walls and horizontal top and bottom walls where the side edges of said walls defining forward and rearward edge surfaces respectively lying in vertical forward and rearward planes,
- a vertical axis extending through said top and bottom walls and being parallel to the vertical plane defined by said forward and rearward edge surface,
- a forward vertical wall member,
- upper and lower horizontal support members attached to said forward vertical wall member,
- first plate members respectively attached to said upper support member and said top wall of said frame member,
- second plate members respectively attached to said lower support member and said bottom wall of said frame member,
- rotational means on each of said first and second plate members aligned with respect to said vertical axis for permitting rotation of said frame member for at least 180.degree. about said vertical axis while providing vertical stability for said frame member,
- each of said first and second plate members having upper and lower plates where one of said plates has at least four spaced apart bearing members and the other of said plates has a circular race for rotatably receiving said bearing members, and one of said plates has a vertical post and the other plates has an elongated slot for slidably receiving said vertical post, said elongated slot being disposed in a direction transverse to said vertical planes,
- said circular race having elongated indentations spaced apart relative to the spacing of said bearing members and aligned parallel to said elongated slot whereby one of said plates in each of said first and second plate members may be moved horizontally with respect to the other of said plates in each of said first and plate members thereby to lock said plate members against relative rotation.
