Inventor(s)Vondrejs; Frank (Downsview, CA); Muller; Vlad (Downsview, CA)
AbstractA 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
