发明名称 Releasable post anchoring device
摘要 Post anchoring and quick release device (10) having a lower post attachment section (20) and an upper anchoring section (22). the device (10) is an elongated, generally rectangular body having in the lower section at least one opening (40,42) in one configuration and at least one opening (66,68) in another configuration and a nail hole (48,50,74,76) beneath each said opening. The nail holes are separated from the openings either by a web (52,54) or a restricted slit (78,80). The device is attached to a post by nails and when the post is to be removed from the ground a bar (B) is used to strike an offset release surface (28) to rupture the web against the nail or to allow the nail so slide through the restricted slit (78,80). In the one the nail is bent down as the device is forced down and in the other the nail slides free of the nail without contacting the nail. The post can then be lifted vertically such that the nail slides free of the device.
