ABSTRACT:
A plate-like element for insertion in a bore or recess to provide a fixing or bearing surface for a shaft or a shaft-like portion of an element includes a laterally centered section having the configuration of a short longitudinally oriented section of a cylindrical wall structure. This laterally centered section, which is correspondingly bowed, has wing-like plate portions at its remote lateral extremities which are co-planar. The remote lateral extremities of the wing-like portions are thinned at their leading edges, having regard for the direction of application of the plate-like element in use. The bowed portion is distinguished at its outer convex surface by an elongated, laterally centered, projection having essentially parallel sides the outermost surface portion of which is flatly arcuate in transverse cross-section and the leading end of which is also arcuate in configuration. What may be considered the leading end of the projection is spaced rearwardly from the leading edge of the plate element, also to facilitate application of the plate. A preferred embodiment of the plate element has an anchoring device centered on and projected from its leading edge. Also, its trailing edge may be provided with an integrated breakaway handle which facilitates its insertion in a bore or a recess.
