发明名称 Rake
摘要 A flexible tine garden rake has a cross arm to which individual tines are attached, the attachments being effected by a retainer strip which is slip-fitted within a channel. The tines have end portions extending crosswise into the channel and terminating in hooks conforming to the interior surface of the channel and lie upon and are backed up by a laterally projecting surface of the cross arm so that the tines are stiffened and are anchored so as to avoid highly localized stress concentration when flexed incidental to normal use.
