Description

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] The present application claims the benefit of the date of the earlier filed provisional application, having U.S. Provisional Application No. 60/448,256, filed on Feb. 19, 2003, which is incorporated herein in its entirety.

BACKGROUND OF THE INVENTION

[0002] 1. Field of the Invention

[0003] The present invention concerns a stabilizer for in-ground members such as stakes, poles and the like. Typical of such in-ground members are the target stakes of horseshoes or ring-toss games, and poles used to support articles such as badminton or volleyball nets, flags or banners, tents, plants, vines and the like.

[0004] 2. Related Art

[0005] The utilization of in-ground members such as target stakes in the games of horseshoes, ring-toss and the like, and support poles for any kind of article is, of course, well known in the art. A problem long encountered in the prior art is lack or loss of stability of such in-ground members, which usually are simply driven into the ground to provide their sole or primary means of support. As used herein, reference to “in-ground” members means and includes stakes, poles and the like, which are primarily or entirely supported by the ground into which they are driven. In this context, the phrase “the ground” means and includes earth, soil, sand, loam and the like, whether bare ground, plant-, grass- or lawn-covered ground, meadow, beach sand, clay, etc.

[0006] One difficulty with such in-ground members is a lack of stability, which may result from loosening of the ground retaining the member in place, which loosening may be aggravated by impacts sustained by, or stresses imposed on, the in-ground member. Such impacts may result from a game, such as when the target stake of a horseshoe game is impacted by the horseshoe striking it, and stresses may be imposed by the wind exerting a force on a tent, plant, flag or banner, or by physical contact by persons, animals or objects with the in-ground member or the article it supports.

SUMMARY OF THE INVENTION

[0007] The above discussed and other drawbacks and deficiencies are overcome or alleviated by a stabilizer for in-ground members that includes a mounting collar having a channel extending therethrough and a plurality of arms. Each of the plurality of arms has a collar end, which is adapted to extend through the channel and engage with the mounting collar. The stabilizer also includes a resilient member that has a bore and is sized to be disposed within the channel so as to support the collar end of each of the plurality of arms at the mounting collar. The resilient member is adapted to receive the in-ground member.

[0008] Additionally, a related method for installing an in-ground member into the ground to dispose a portion thereof beneath the surface of the ground and to leave a portion thereof extending above the surface of the ground, the method includes providing a plurality of arms that each have a collar end and a mounting collar and inserting the collar end through the channel of the mounting collar so that the collar end engages with the mounting collar. In addition, the method includes inserting a resilient member, which has a bore, into the channel of the mounting collar so that the resilient member supports the collar end and inserting an in-ground member into the bore so that the resilient member is forced against the mounting collar to provide rigidity to the plurality of arms. The method also includes driving the plurality of arms into the ground.

DETAILED DESCRIPTION

[0013] Referring to FIGS. 1-3, there is shown a stabilizer 10 aligned with an in-ground member 12. In-ground member 12 has an above-ground portion 12a which extends vertically above the surface S of the ground G, and has a below-ground portion 12b which is embedded in the ground G.

[0014] Stabilizer 10 includes a mounting collar 16 that has a channel 18 extending therethrough. A plurality of arms is shown as four arms 20a, 20b, 20c and 20d. Arms 20a-20d are disposed at ninety-degree intervals about mounting collar 16, i.e., adjacent ones of the arms are at right angles to each other. Each arm 20a-20d includes a stabilizing section 22a, 22b, 22c, and 22d that extend radially from mounting collar 16, and an anchoring section 24a, 24b, 24c, and 24d that extend downwardly from stabilizing section 22a-22d. When stabilizer 10 is used for a horseshoe game, each stabilizing section 22a-22d may be in a range of approximately 8 inches to 10 inches and each anchoring section 24a-24d is at least 10 inches. In an exemplary embodiment, each stabilizing section 22a-22d is disposed approximately four inches below the ground.

[0015] The figures illustrate that stabilizing section 22a-22d and anchoring section 24a-24d are a continuous member with approximately a ninety-degree angle between the two sections. The advantage of this is easy of manufacturing and assembly. In addition, stabilizing section 22a-22d may also be a separate piece from anchoring section 24a-24d and the two sections may be couple together by a bolt, screw, weld, or any other known means for attaching two sections.

[0016] Each anchoring section 24a-24d may also include a respective projection or foot 26a, 26b, 26c, and 26d, which helps to anchor the arms 20a-20d into the ground G. Each arm 20a-20d includes a respective collar end 30a-30d with a respective nub 32a-32d. Each collar end 30a-30d extends from stabilizing section 22a-22d in a downwardly direction through channel 18 so that nubs 32a-32d engage with mounting collar 16. Nubs 32a-32d help to keep the assembly from being forced upward upon impact. It will be appreciated that collar ends 30a-30d engage mounting collar 16 without the assistance of any mechanical means such as welds, bolts, screws, or the like.

[0017] Stabilizer 10 also includes a resilient member 40 that is inserted into channel 18 and helps to secure collar ends 30a-30d to mounting collar 16. Resilient member 40 also absorbs the impact when there is forced placed on in-ground member 12, i.e., when a horseshoe ring impacts in-ground member 12, and also ensures that in-ground member 12 does not slip. Resilient member 40 may be made from foam, rubber, or any material that is compressible and resists compression. In addition, resilient member may also be a spring device or any type of device that is compressible and resists compression. Resilient member 40 includes a bore 42 that extends through member 40. Resilient member 40 is shaped so that it extends through mounting collar 16. In an exemplary embodiment, resilient member 40 has a curved body 44 and ears 46 (barbelled shaped). Ears 46 expand over a top edge 48 and a bottom edge 50 of mounting collar and help to hold resilient member in place within mounting collar 16. Bore 42 is sized to be smaller than in-ground member 12 so that when in-ground member 12 is received into bore 42, resilient member 40 is compressed and securely holds in-ground member 40 at mounting channel 16.

[0018] Referring to FIG. 4, an alternative embodiment of arms 20a-20d is illustrated. In addition, while only one arm is illustrated, it is understood that the embodiment is applicable to each of the arms 20a-20d. Anchoring section 24d may include an anchor fin 54d, which is attached to anchoring section 24d. In addition, anchoring section 24d may also include a plurality of holes 56 so that an installer may choose the height at which to attach anchor fin 54d to anchoring section 24d. By providing anchoring section 24d with a plurality of holes 56, anchor fin 54d may be positioned at various heights along anchoring section 24d. This enables variation of the depth of individual anchor fins below ground surface when the installation is complete, and/or permits fastening of more than one anchor fin to a given anchoring section. Each anchor fin 54a, 54b, 54c (not shown), and 54d may be arranged at similar heights or at least one anchor fin may be offset for one of the other anchor fins. In an exemplary embodiment, anchor fin 54d is somewhat fan-shaped. Anchor fin 54d may be attached to anchoring section 24d by a mechanical fastener, such as a bolt, screw, weld, or the fins may ride in a track (not shown) on the anchoring section, and may be locked in place at a desired position by a detent or other suitable locking member.

[0019] Referring again to FIG. 3, an exemplary embodiment for arranging stabilizer 10 in ground G is illustrated. If stabilizer 10 is used for a horseshoe game, there is enhanced stability by arranging stabilizer 10 in an X formation so that a horseshoe is thrown at in-ground member 12 from a direction 60. Direction 60 shows the impact force that would be imposed on in-ground member 12 if it served as the target stake of a horseshoes game in which the horseshoes were pitched from a position that causes them to travel along a path substantially parallel to, and in the direction 60.

[0020] Referring to FIGS. 1-3, in order to attain the assembly of stabilizer 10 and in-ground member 12, the following method is utilized. A hole for the mounting collar 16 and four trenches, for each stabilizing section 22a-22d of each arm 20a-20d. Stabilizer 10 is then assembled by sliding each collar end 30a-30d through channel 18 so that nubs 32a-32d hook onto bottom edge 50. Resilient member 40 is then inserted into channel and in-ground member 12 is slide into bore 42. Anchoring sections 24a-24d are then placed on the ground G with foot 26a-26d each being located in one of the trenches and with mounting collar 16 located directly above the hole. Anchoring sections 24a-24d are then driven into the ground by either pushing on arms 20a-20d or using a sledgehammer to drive anchoring sections 24a-24d into the ground G. Repeated blows distributed in sequence to each arm 20a-20d will drive stabilizer 10 into the ground to the position illustrated in FIG. 2. If the ground G comprises a loose soil or sand, for example, beach sand or a sand or loam used in a game such as horseshoes or ring-toss, stabilizer 10 will, of course, be easily driven into the ground G and holes and trenches may not be necessary. Once stabilizing sections 22a-22d are located within the trenches and mounting collar 16 is located in the hole, the hole and trenches are backfilled so as to cover stabilizer 10 and to have a section of in-ground member 12 extending above ground G.

[0021] It will be appreciated that stabilizer 10 will provide an extremely secure retention of in-ground member 12 within ground G, and will provide a high degree of resistance to impacts in any direction, but especially in the direction of the arrow 60 of FIG. 3, thereby maintaining in-ground member 12 and its above-ground portion in desired alignment, usually vertical, relative to the surface S of ground G.

[0022] While four arms 20a-20d have been illustrated as extending radially outwardly from mounting collar 16 at ninety-degree intervals, more or fewer than four arms may be used and they may be positioned at equal or unequal radial intervals, depending on the nature of the ground and whether directionality of highest resistance to impact is desired.

[0023] It will be appreciated that the in-ground member of the invention need not be a target stake for horseshoes or ring-toss as illustrated, but may be a tent pole, fence post, some other type of post, a pole or other in-ground member, or the like. Such in-ground members, alone or in cooperation with similar or identical in-ground members, may serve to support any of a wide range of articles, for example, a badminton or volleyball net or the like, a flag or banner, a tent, growing plants and vines, etc. Whatever the purpose of the in-ground member, a stabilizer in accordance with the present invention, such as stabilizer 10, will enormously enhance the stability of any type of in-ground member.

[0024] The advantages of stabilizer 10 are that stabilizer 10 is inexpensive to make and it can be shipped disassembled. Stabilizer 10 is also easy to assemble and may be assembled in the field at the time of installation into the ground.

[0025] While the invention has been described with respect to specific preferred embodiments thereof, it will be appreciated that numerous variations may be made to these specific embodiments which variations nonetheless lie within the spirit and scope of the present invention. For example, the stabilizer may be made of any suitable material, metal, plastic or a combination thereof, and it may be formed of components which are secured to each other by any suitable means, or it may be an integrally-formed, i.e., one-piece, stabilizer. The stabilizer of the present invention may be dimensioned and configured to be fitted onto an existing in-ground member, or it may be pre-assembled with an in-ground member to provide a unitary assembly comprising a stabilizable in-ground member.
