  • Publication number: 20110290187
    Abstract: A protective enclosure for a wild bird feeder or for feeding wild birds has apertures sized to selectively restrict access to its interior and comprises an outer mesh section (1) overlying an inner mesh section (2), said mesh sections being loosely mutually connected by one or more link members (5) extending into a space between the mesh sections and allowing relative lateral displacement of the inner and outer mesh sections to vary the effective size of said apertures. The link members are suitably hooked over horizontal bars (6d) of the outer mesh section and the effective aperture size (A/a) can be varied by rotating the inner mesh section (2).

  • Patent number: 5967359
    Abstract: A receptacle (1) which may contain food or drinks or may be a plant container, for example, is provided with an upright central locating tube (2) which is attached to an aperture in a recess (3) in its base and is mounted on e.g. a parasol pole (6) by means of a jubilee clip (5) which encircles and grips spring fingers (4) which extend from the bottom end of the locating tube. The above clamping arrangement is concealed within the recess (3) and hence the appearance is enhanced. In a further embodiment, the spring fingers are omitted and the locating tube is provided with apertures above and below the surrounding region of the base which enable the receptacle to be attached to the supporting pole by pegs or threaded fixing means and, when the receptacle is dismounted from the pole, function as drainage and/or ventilation holes.
