Abstract: An infant's amusement device comprises a suspension bar adapted to be supported in a horizontal position during use for suspending a plurality of toys therefrom, a pair of supporting bars disposed in a common plane at the opposite ends of the suspension bar, and a pair of juncture bars joining the supporting bars to the opposite ends of the suspension bar and lying in a common plane with the suspension bar. The latter common plane is at an acute angle of 30.degree.-75.degree. to the common plane of the supporting bars, whereby the supporting bars stably support the suspension bar in a horizontal position on and spaced above a horizontal surface to enable the infant to lie under the suspension bar, parallel to and straddled by the supporting bars, and to touch the toy suspended from the suspension bar. Three embodiments are described, namely a unitary construction, a foldable three-part construction, and a foldable five-part construction.

Abstract: A coaxial joint for joining inner and outer cylindrical members permitting rotational and/or linear movement between them, comprises an outer bushing sleeve non-rotatably receivable within the outer cylindrical member, an inner bushing sleeve formed with a central bore for receiving the inner cylindrical member; a first group of longitudinally-extending, circumferentially-spaced ribs formed between the inner and outer sleeves; and a second group of such ribs formed in staggered relationship with respect to the first group on the outer face of the outer sleeve and effective, when forcibly received within the outer cylindrical member, to distort inwardly the portions of the outer sleeve between the first group of ribs and thereby to minimize the distortion of the inner sleeve.
