Modular wall panel structure

Claim 2

A wall panel module having a rectangular frame comprising outwardly open side channels with laterally outwardly extending resilient outer edges adapted for abutting the resilient outer edges of like modules to form a vertical partition wall and the like having a resilient butt joint spacing apart the interfacing edges of adjoining panels, a vertical spline in at least one side channel having a width not exceeding the lateral depth of said channel and movable laterally therein to clear the outer edge of said channel, the web of said channel having a longitudinal internal rib, clip means mounted on said rib for releasably holding said spline in a position medial of said outer edge, and said spline being engageable by traversing a resilient edge of said channel for moving said spline laterally in said channel.

Claim 3

A wall panel module as defined in claim 1, wherein the channels have internal side grooves adapted to cooperate with said internal ribs to receive flexible plates for folding under and snubbing sheet material covering the faces of the panel.

Claim 4

A wall panel module as defined in claim 1, wherein the clip means is channel shaped with resilient fingers embracing said spline, and lugs on said fingers for holding said spline in medial position.

Claim 5

A wall panel module as defined in claim 3, wherein the clip means has substantially rigid guide legs adjacent to said resilient legs for guiding said spline laterally.

Claim 6

A wall panel module as defined in claim 1, wherein the channels have internal side grooves adapted to cooperate with said internal ribs to receive flexible plates for folding under and snubbing sheet material covering the faces of the panel, and the clip means is channel shaped with resilient fingers embracing said spline, and lugs on said fingers for holding said spline in medial position.

Claim 7

A vertical partition wall comprising modular wall panels each having outwardly open side channels with laterally outwardly extending resilient outer edges in abutment with the resilient outer edges of adjoining panels to form a resilient butt joint spacing apart the interfacing edges of adjoining channels, a vertical spline in each pair of adjoining side channels having a width not exceeding the depth of one channel and movable laterally therein, the webs of said channels having longitudinal internal ribs, clip means mounted on the rib of at least one of each pair of adjoining channels for releasably holding the spline in a position medially of the butt joint between the resilient outer edges of said channels, and said spline being engageable through the butt joint between the resilient outer edges of two adjoining channels for moving said spline laterally in said adjoining channels.

Claim 8

A vertical partition wall comprising modular wall panels each having outwardly open side channels with laterally outwardly extending resilient outer edges in abutment with the resilient outer edges of adjoining panels to form a resilient butt joint spacing apart the interfacing edges of adjoining channels, a vertical spline in each pair of adjoining side channels having a width not exceeding the depth of one channel and movable laterally therein, the webs of said channels having longitudinal internal ribs, clip means mounted on the rib of at least one of each pair of adjoining channels for releasably holding the spline in a position medially of the butt joint between the resilient outer edges of said channels, and said spline being engageable through the butt joint between the resilient outer edges of two adjoining channels for moving said spline laterally in said adjoining channels.

Claim 9

A vertical partition wall as defined in claim 6, wherein the side channels each have internal side grooves for receiving angular corner connecting plates.

Claim 10

A vertical partition wall as defined in claim 6, wherein the channels have internal side grooves adapted to cooperate with said internal ribs to receive flexible plates for folding under and snubbing sheet material covering the faces of the panels.

Claim 11

A vertical partition wall as defined in claim 6, wherein the clip means is channel shaped with resilient fingers embracing said spline, and lugs on said fingers for abutting said spline in medial position.

Claim 12

A vertical partition wall as defined in claim 9, wherein the clip means has substantially rigid guide legs adjacent to said resilient fingers for guiding said spline laterally.

Claim 13

A vertical partition wall as defined in claim 6, wherein the channels have internal side grooves adapted to cooperate with said internal ribs to receive flexible plates for folding under and snubbing sheet material covering the faces of the panel, and the clip means is channel shaped with resilient fingers embracing said spline, and lugs on said fingers for holding said spline in medial position.
