1. The present invention provides a readily portable, light-weight ground stand, having a base portion for ready insertion into suitable terrain, with an upstanding tubular portion to carry a table and to receive the shaft of a beach umbrella or other device in inserted, supported relation therein.
2. A large number of prior support devices exist for use in providing ground-penetrating attachments. Most, if not all of these are of metal, and require the use of tools such as hammers to drive the associated spike portions into the ground. Most are intended for permanent fixtures such as fence posts, rural mailboxes, games net support posts and the like.
The present invention provides a lightweight, portable post-anchor that is readily secured to the ground without the use of tools, and which is readily removed from its anchorage, for re-use elsewhere, or on succeeding occasions. The subject anchor may be used with a beach-style umbrella, and/or in combination with a table. It can also be used to hold citronella torches, for securing games nets; and for signage such as real-estate signs.
The subject ground anchor is of high strength plastic, having a base plate with a number of spikes in mutually spaced relation projecting downwardly from the periphery of the plate. The plate is reinforced on its upper and lower surfaces by a series of ribs and gussets, the upper series of ribs and gussets being so arranged to provide at least two loading spaces upon which a user may place their shod foot, to exert their body weight downwardly against the ground anchor, to force the spikes down into the ground. The lower surface of the base plate has ribs underlying the loading spaces, to reinforce the base plate against undue deformation under the thus applied load, with gussets reinforcing the spike portions. An upstanding, gusset-reinforced tubular portion projecting from the base plate upper surface is sized to receive the shaft of a beach umbrella in inserted relation therein. A table may also be mounted upon the anchor, with or without the umbrella.
The base plate is perforated, to allow any moisture or detritus within the tubular portion to exit downwardly into the ground. The upstanding tubular portion has stiffening gussets connecting with the base plate, to enable use of the tubular portion as a lever, in removing the ground anchor from an imbedded position, for removal and further use elsewhere.
The underlying reinforcing ribs are sufficiently deep and slender that they readily penetrate and compact the surface of the ground, and serve to stabilize the anchor with the ground.
Certain embodiments of the invention are described by way of illustration, without limitation thereto other than as set forth in the accompanying claims, reference being made to the accompanying drawings, wherein:
Referring to
A deep bracing rib 22 extends laterally between the pairs of gussets 16, in mutual bracing relation therewith.
A central annular reinforcement ring 24 surrounds an opening 26 that connects with the cylindrical interior 30 of the hollow post portion 28 of the anchor 10.
On the underface (
The post 28, which is integrally moulded with the other portions of the base plate 10, has four diagonal gusseted stiffener ribs 34.
The post 28 has an internally threaded boss 36 for a headed locking screw 38 which releasably engages the shaft 42 of the umbrella 40 (
Referring to
Turning to
In use, the anchor 10 is first installed, being thrust down under foot pressure applied against the rib-reinforced end portions of base plate 12. In harder turf, such as beside a sports field, the spikes 14 will afford a good grip, without having to force the ribs 22 fully down into the turf. However, particularly in sand, the bracing ribs 22 can be forced down so as to entrap a mass of sand in stabilizing relation with the base plate 12, to stabilize it against horizontal displacement as foot pressure is applied.
It will be understood by those skilled in the art that the above disclosure is directed primarily to specific embodiments of the present invention, and that the subject invention is susceptible of reduction to practice by those skilled in the art in other embodiments that fall within the scope of the appended claims.
