There is provided a new and useful apparatus for applying a removable protective cover to an optical disc in which the optical disc has a circular configuration, an aperture centered therein and an outer edge. The cover comprises at least one sheet of film of generally circular configuration which corresponds to the circular configuration of the disc. The cover is constructed of a material that will not adversely interfere with the read process of the disc when the cover is in place about the disc. The cover further comprises a plurality of resilient clasps spaced about a circumferential edge of the film to engage the disc about its outer edge in a snap-on spring-like fit. The apparatus has a base to hold the cover with the clasps in a closed position oriented upwardly away from the base, a moveable expanding means to urge the clasps from the closed position to an open, disc-receiving position, centering means to orient and hold the disc concentric with the cover and a top having an inside face and an outside face. The top comprises press means to exert a force on the disc in the direction of the cover, whereby the force urges the edge of the disc to co-operate with the expanding means to expand the clasps into the open disc-receiving position while urging the disc in position within the cover whereby the clasps return to the closed position thereby engaging the edge of the disc in the snap-on spring-like fit.

Applicator for protective cover for an optical disc

There is provided a new and useful protective cover for an optical disc of circular configuration having a circular aperture centered therein and having an outer edge. The protective cover is a sheet of film of generally circular configuration corresponding to the configuration of the disc, wherein the film is of a material that will not interfere with the read process of the disc when the cover is in place about the disc. The protective cover has a plurality of clasps spaced about a circumferential edge of the film to engage the disc about its outer edge in a snap fit. The invention also relates to a method of applying such a protective cover to such an optical disc comprising the steps of holding the cover with the clasps in a closed position oriented relative to the film toward said disc, expanding the clasps to an open position wider than an outside diameter of the disc, placing the disc within the expanded clasps, concentric with the cover and returning the clasps to the closed position whereby they engage the disc about the outer edge in a snap fit.

A multi-tiered system of leveller units for the levelling of recreational vehicles. The leveller units each comprise a planar body, with upper and lower surfaces circumscribed by edges. The body of each unit bears a plurality of pins upwardly extending from spaced locations in the upper surface and has a plurality of pin-engaging pockets formed in the lower surface to matably receive corresponding pins of other similar units. The pins are of slightly smaller size than the corresponding pockets so that when the pins of one unit are associated with the pockets of another, there is provided a loose engagement therebetween. The body may be formed of a discontinuous webbing providing light-weight strength and support to the units to support the large loads placed thereupon.
