Abstract
Abstract A modular panel system consists of a plurality of panels. Each panel carries at least one and preferably two pivotal connection devices. Each pivotal connection device has thereon a hook-like or latch-like member which can fit into a slot to releasably connect one panel to an adjacent panel. A particular design of double axis hinge is also disclosed, which serves as the pivotal connection device.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
242 words
A modular panel system, comprising a plurality of panels, each panel having one or more hinges, and at least one of the hinges of the system including first and second pin members, each having parallel limbs of circular cross-section forming hinge pins, and first and second hinge plates, each of the hinge plates having first and second limb-receiving journals offset and noncollinear with respect to each other for rotatably receiving the first and second pin members, respectively, at least one of the hinge plates of each hinge having a hook-like member thereon whereby said hinge can be releasably connected to an adjacent panel, such that one hinge plate can pivot through 360° relative to the other, the first 180° of this movement being pivoting about a first common axis defined by collinearity of the axis of pivoting of the second limb of the first pin member within the first journal of the second hinge plate and the axis of pivoting of the first limb of the second pin member within the second journal of the first hinge plate, and the second 180° of the said movement being pivoting about a second common axis defined by collinearity of the axis of pivoting of the first limb of the first pin member within the first journal of the first hinge plate and the axis of pivoting of the second limb of the second pin member within the second journal of the second hinge plate.
Claim 2
Dependent Claim
242 words
A modular panel system, comprising a plurality of panels, each panel having one or more hinges, and at least one of the hinges of the system including first and second pin members, each having parallel limbs of circular cross-section forming hinge pins, and first and second hinge plates, each of the hinge plates having first and second limb-receiving journals offset and noncollinear with respect to each other for rotatably receiving the first and second pin members, respectively, at least one of the hinge plates of each hinge having a hook-like member thereon whereby said hinge can be releasably connected to an adjacent panel, such that one hinge plate can pivot through 360° relative to the other, the first 180° of this movement being pivoting about a first common axis defined by collinearity of the axis of pivoting of the second limb of the first pin member within the first journal of the second hinge plate and the axis of pivoting of the first limb of the second pin member within the second journal of the first hinge plate, and the second 180° of the said movement being pivoting about a second common axis defined by collinearity of the axis of pivoting of the first limb of the first pin member within the first journal of the first hinge plate and the axis of pivoting of the second limb of the second pin member within the second journal of the second hinge plate.
Claim 3
Dependent Claim
65 words
A modular panel system according to claim 1 in which each hinge plate of at least said one hinge has a hook-like member one of which cooperates with a slotted latch plate on one of the panels and the other of which cooperates with a slotted latch plate on another of the panels in order to temporarily connect the two panels for relative pivotal movement.
Claim 4
Dependent Claim
52 words
A modular panel system according to claim 1 in which each panel has a frame comprising an extruded metal strip, the strip having a cross-section defining a channel, the internal walls of the channel being grooved to cooperate with the thread of a bolt disposed to secure a hinge to the panel.
Claim 5
Dependent Claim
48 words
A modular panel system according to claim 3 in which the metal strip forms the periphery of a square or rectangular panel and further including a joining bar located in the channel portions of the two abutting ends of the strip to connect the ends to one another.
Claim 6
Dependent Claim
91 words
A modular panel system according to claim 1 wherein each hinge is separable from a panel associated therewith and further includes a hook-like member which cooperates with a slotted latch plate on the panel and each hinge plate has tags defining recesses for the reception of bolts, and wherein each panel has a frame comprising an extruded metal strip, the strip having a cross-section defining a channel, the internal walls of the channel being grooved to cooperate with the threads of the bolts disposed to secure the hinge to the channel.
