MULTI-TIERED SYSTEM OF LEVELLER UNITS

摘要

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 pluralit y of pin-engaging pockets formed in the lower surface to matably receive correspondin g pins of other similar units. The pins are of slightly smaller size than the corr esponding pockets so that when the pins of one unit are associated with the pockets of ano ther, 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 t o support the large loads placed thereupon.
