| Abstract | A panel structure, as used for space dividers and other purposes, has an
identical frame member at each side. Each frame member comprises an
extrusion of the same cross-sectional shape, having on one side surface at
least one formation comprising a projection and a recess disposed
symmetrically about a median plane which extends longitudinally of the
extrusion. The frame members extend vertically at each end of a central
portion of the panel with their respective side surfaces facing outwardly.
Two adjacent panels are held together by bringing the endmost frame
members of the respective panels into contact so that the formations on
the respective members interfit. Locking members are then snapped into
slots in the respective frame members. |

FIELD OF THE INVENTION
This invention relates to frame members, such as are used in space dividers
and screens for sub-dividing office and other space, and in other panel
structures. In particular, the invention is concerned with frame menders
which are intended to be used vertically at the sides of a panel
structure, and which are designed to permit two or more such panel
structures to be connected together by inter-engaging formations on the
frame members.
BACKGROUND OF THE INVENTION
It has been proposed to use at the vertical sides of a divider or screen an
extruded, elongate member, which has a particular formation on its
sideways facing surface. The formation on one side of one divider engages
with the formation on the adjacent side of a further divider. Once the
formations are engaged to each other, a locking member may be applied to
retain the members and thus the screens together.
Conventionally, two different forms of frame member are required, one being
used at one side of the screen and the other being used at the other side.
The use of two different forms of frame member (that is, frame members
having different transverse cross-sectional shapes) requires two different
dies to make the frame members. Also, in assembling a screen, care must be
taken that the correct frame member is used at each side of the screen.
BRIEF DESCRIPTION OF THE INVENTION
The present invention provides a frame member having a particular
cross-sectional shape which can be used for both sides of a screen or
other panel structure.
The frame member of the invention is of elongate form and has a side
surface adapted to co-operate with a like side surface of a second similar
frame member. The side surface has at least one formation which extends
longitudinally of the member and is of uniform cross-sectional shape
throughout its length and which comprises a projection and a complementary
recess. The projection and recess are disposed on respectively opposite
sides of and symmetrically with respect to a longitudinal median plane of
the member which extends normal to said surface. The frame member further
includes means for receiving a locking member for maintaining a frame
member in side-by-side relationship with a said second similar frame
member with the said side surfaces of the respective members in abutment.
The formations of the side surfaces of the respective frame members then
inter-engage for preventing lateral movement between the members.
Preferably, two U-shaped locking members are employed and fit into
laterally directed slots at ends of the side surfaces of the respective
frame members.
In conventional arrangements for connecting the two adjacent frame members
of a pair of screens, the two frame members are locked together by a
locking member which slides longitudinally over formations on the frame
members. It is a preferred feature of the present invention that the
locking member is applied by sideways movement; that is, movement normal
to the longitudinal axis of the frame member.
Additional formations can be provided on the frame member for the
attachment of, or the attachment to, other members.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIG. 1 illustrates, in transverse cross-section, a frame member 10, which
in this example is a hollow metal extrusion. The frame member is elongate,
of a length useable as a frame member for a divider or screen, or other
panel structure.
Frame member 10 has a side surface 12 adapted to co-operate with a like
side surface of a second, similar frame member (see FIGS. 2 and 3). Side
surface 12 has two formations, each comprising a projection and a recess
respectively. In the example illustrated, projection 17 and recess 18
comprise one such formation and are disposed on respectively opposite
sides of and symmetrically with resect to a longitudinal median plane A--A
of member 10. Projection 16 and recess 19 comprise a second such formation
and are similarly disposed with re | | |
