ABSTRACT:
A concealable handle for carrying an article having one or two elonated channels with a U-shaped cross-section. The handle works in combination with the channels, the handle comprising two elongated straps proportioned to fit inside the channels, one inside each channel. Each strap has a pivot at one end and an attachment at the opposite end. The pivot is too wide to slide out of the channel and is proportioned with longitudinal dimension about equal to the distance between the bottom of the channel and the lips. The latitudinal dimension, perpendicular to the longitudinal dimension, is shorter than the longitudinal dimension and the intersection of the edges is rounded. The dimensions of the pivot allow sliding of the strap means along the length in the channel and free rotation of the strap out of the channel to the perpendicular position. At the perpendicular, the pivot is restricted from further rotational movement. Further, at this position, movement of the pivot along the channel is restricted. When one strap in each channel is used, the attachment means of the straps attach together to create a graspable handle.
