DEFINITION

Classification: 410/77

Retainer:

(under subclass 52) Structure in which the accommodating means is attached to the freight carrier and engages a part of the stowed load bearer adequately to effect securement thereto; i.e., to inhibit displacement of the load carrier on the freight carrier in both the lateral and vertical direction.

(1) Note. Inhibition of displacement in the lateral direction is presumed when means inhibiting displacement in the vertical direction is brought into play. However, merely inhibiting displacement in the lateral direction will not be assumed to constitute, in itself, retainer structure as herein defined but will be recognized only as generic accommodating means. Rigid material hold-down structure of the hold-down type is predominantly the expedient by which to inhibit vertical displacement of a load--and, typically, lateral displacement as well (note, however, the load bearer (load lashing retainer)* in subclass 85). The basics of a hold-down is paraphrased from the definition of Class 248, Supports, subclass 501, as follows: --form-sustaining structure having an undersurface portion for engaging an upwardly facing portion of a article to retain the article on a support surface--; to wit, in the instant context, a load bearer on a freight carrier surface.
