A transportable harp rack for a plurality of panels, the harp rack including: a) a frame including: i. at least one base member; and, ii. at least a pair of spaced apart upright members extending at an angle to the at least one base member; b) at least two securing assemblies provided relative to the frame, at least one securing assembly provided relative to the at least a pair of upright members and at least one other securing assembly, each securing assembly including: i. a plurality of panel tongues arranged in pairs, the panel tongues in each pair spaced from one another by a respective receiving gap configured to receive a portion of a panel therein; ii. at least one of the panel tongues in each pair provided with a resilient block therein, at least partially defining the receiving gap, the resilient block including at least one opening thereinto; and iii. a shaped spigot mounted relative to a drive mechanism to selectively move the shaped spigot relative to the at least one opening in the resilient block between a rest condition in which a panel can be inserted into the receiving gap and to cause deformation of the resilient block into an expanded clamping condition in which a portion of the resilient block is moved to clamp the panel within the receiving gap. a) a frame including: i. at least one base member; and, ii. at least a pair of spaced apart upright members extending at an angle to the at least one base member; i. at least one base member; and, ii. at least a pair of spaced apart upright members extending at an angle to the at least one base member; b) at least two securing assemblies provided relative to the frame, at least one securing assembly provided relative to the at least a pair of upright members and at least one other securing assembly, each securing assembly including: i. a plurality of panel tongues arranged in pairs, the panel tongues in each pair spaced from one another by a respective receiving gap configured to receive a portion of a panel therein; ii. at least one of the panel tongues in each pair provided with a resilient block therein, at least partially defining the receiving gap, the resilient block including at least one opening thereinto; and iii. a shaped spigot mounted relative to a drive mechanism to selectively move the shaped spigot relative to the at least one opening in the resilient block between a rest condition in which a panel can be inserted into the receiving gap and to cause deformation of the resilient block into an expanded clamping condition in which a portion of the resilient block is moved to clamp the panel within the receiving gap. i. a plurality of panel tongues arranged in pairs, the panel tongues in each pair spaced from one another by a respective receiving gap configured to receive a portion of a panel therein; ii. at least one of the panel tongues in each pair provided with a resilient block therein, at least partially defining the receiving gap, the resilient block including at least one opening thereinto; and iii. a shaped spigot mounted relative to a drive mechanism to selectively move the shaped spigot relative to the at least one opening in the resilient block between a rest condition in which a panel can be inserted into the receiving gap and to cause deformation of the resilient block into an expanded clamping condition in which a portion of the resilient block is moved to clamp the panel within the receiving gap.
