Abstract
A collapsible stand that is designed for use on loose soil or sand. The collapsible stand has a central shaft and an auger that extends from the shaft. A slide hub moves along the central shaft between a first position and a second position. Legs radially extend from the central shaft. Linkages are used to interconnect the legs with the slide hub. When the slide hub moves to its first position along the central shaft, the linkages move the legs into a stowed configuration. When the slide hub moves to the second position, the linkages move the legs into a deployed configuration. The central shaft is set into the ground using the auger. The legs are deployed, wherein the legs have footpads that rest upon the ground. The pull of the auger biases the footpads against the ground and create a highly stable stand.
Description
- This application claims the benefit of U.S. Patent Application No. 62/665,231, filed May 1, 2018.
- In general, the present invention relates to tripod stands where a centered shaft is supported by radially extending legs. More particularly, the present invention relates to tripod stands that are intended for use at the beach and in other loose soil environments.
- There are many tripod stands in the marketplace for holding outdoor objects, such as shade umbrellas. However, many such stands are designed to support objects on hard flat surfaces, such as house decks and yard patios. When such a tripod is brought to a beach and placed in the sand, it fails to work. The sand is too soft to support the legs of the tripod. The legs of the tripod, therefore, sink into the sand at different rates. This causes the stand to tilt and the umbrella to rapidly fall. It is for this reason that people elect not to use tripod stands at the beach. Rather, at the beach, most people bury the base of an umbrella in the sand and utilize the sand itself to support the umbrella.
- Some hybrid umbrella stands have been invented that utilize a central post that is buried and tripod legs that help stabilize the central post. Such hybrid designs are exemplified by U.S. Pat. No. 2,195,391 to Hunter. However, the tripod legs used on hybrid designs are often too small of a footprint to use on soft sand or soil. As a result, most of the vertical support comes from the shaft of the umbrella stand that is buried. Very little support comes from the tripod legs.
- Although burying the base of a pole in the sand is an effective way to anchor an umbrella, many people do not like digging in the sand. Digging in the sand can be accomplished with tools, but this requires that the tools be carried to the beach. Holes can be dug by hand, but this obviously makes a person's hands sandy. Also, the sand is abrasive and can irritate cuts and ruin painted fingernails. It is for these reasons that many people prefer using umbrella stands on the beach that do not require digging in order to be set into the sand. Umbrella stands that contain augers at their bottoms have become popular. The augers dig into the ground by turning the umbrella stand while applying downward pressure. Such umbrella stands are exemplified by U.S. Pat. No. D630,834, which is owned by the present applicant, and U.S. Patent Application Publication No. 2014/0007487 to Schwiebert.
- A problem associated with augered umbrella stands is that they are difficult to turn. The force needed to turn an augered umbrella stand is proportional to the depth of the auger. Although most individuals may be able to turn an augered umbrella sand a short depth into soft sand. Few people have the grip strength and/or arm strength needed to fully set the augered umbrella stand or drive the augured umbrella stand into packed sand or soil.
- A need therefore exists for an improved umbrella stand that is specifically designed to be effective on sand yet does not require a person to dig into the sand and does not require superior turning strength. These needs are met by the present invention as described and claimed below.
- The present invention is a collapsible stand that is designed for use on loose soil or sand. The collapsible stand can be used to anchor an umbrella, flag, fishing pole or any other such secondary object. The collapsible stand has a central shaft. The central shaft has a first end and an opposite second end. An auger extends from the second end and enables the central shaft to be screwed into the ground.
- A slide hub is provided on the central shaft. The slide hub reciprocally moves along the central shaft between a first position and a second position. A plurality of legs radially extends from the central shaft near its second end. The legs are connected to the central shaft, or a fixed hub on the central shaft, with hinge connections. This enables the legs to rotate about the hinge connections.
- Linkages are used to interconnect the legs with the slide hub. When the slide hub moves to its first position along the central shaft, the linkages move the legs into a stowed configuration. In the stowed configuration, the legs are generally parallel to the central shaft. When the slide hub moves to the second position, the linkages move the legs into a deployed configuration. In the deployed configuration, the legs are generally perpendicular to the central shaft.
- In use, the central shaft is set into the ground by rotating the auger into the ground. The legs are deployed, wherein the legs have footpads that rest upon the ground. The pull of the auger biases the footpads against the ground and create a highly stable stand, even when used on loose sand.
- For a better understanding of the present invention, reference is made to the following description of exemplary embodiments thereof, considered in conjunction with the accompanying drawings, in which:
-
FIG. 1 is front view of a stand assembly in its deployed configuration; -
FIG. 2 is a front view of a stand assembly in its stowed configuration; -
FIG. 3 shows the stand assembly being deployed on a sandy surface; and -
FIG. 4 shows an alternate embodiment where the stand assembly is integrated into the structure of an umbrella. - The present invention stand assembly can be configured in many ways and can be adapted for a specific use. For example, the stand assembly can be configured as a simple stand, that can be used to hold an umbrella pole or a fishing pole. Alternatively, the stand assembly can be integrated into the pole of an umbrella. Additionally, the auger used on the stand can be configured for different types of sand and soil. Although the present invention can be used in many such applications, only two exemplary systems are illustrated and described. The exemplary embodiments are selected in order to set forth two of the best modes contemplated for the invention. The illustrated embodiments, however, are merely exemplary and should not be considered limitations when interpreting the scope of the appended claims.
- Referring to
FIG. 1 andFIG. 2 , astand assembly 10 is shown. Thestand assembly 10 is set into the ground and can be used to hold any elongated secondary object, such as a beach umbrella or the handle of a fishing pole. Accordingly, thestand assembly 10 has acenter shaft 12 with afirst end 13 that is open to receive the secondary object. Optional locking handles 15 can be positioned at thefirst end 13 of thecenter shaft 12 to help lock secondary object into thecenter shaft 12. The locking handles 15 also assist in the carrying and turning of thestand assembly 10. - The opposite second end 14 of the
center shaft 12 is attached to anauger 20. Theauger 20 is designed to be driven into the ground by rotational movement. Theauger 20 has a taperedbody 16. The taperedbody 16 hasexternal flights 18 that enable theauger 20 to be easily screwed into sand or other loose soil by rotating theshaft 12 with a clockwise rotation. - At least three
support legs 22 are provided. In the shown embodiment, threesupport legs 22 are used to create a tripod formation. However, it will be understood that four support legs can also be used to create a stable quadpod formation. Thesupport legs 22 are foldable between a stowed position (FIG. 2 ) and a deployed position (FIG. 1 ). In the stowed position, thesupport legs 22 are parallel or nearly parallel to thecenter shaft 12. In the deployed position, thesupport legs 22 are perpendicular or nearly perpendicular to thecenter shaft 12. - Each of the
support legs 22 has afirst end 24 and an oppositesecond end 26. A mountinghub 28 is affixed to thecenter shaft 12 proximate the second end 14 of thecenter shaft 12. The mountinghub 28 is set in a fixed position. The mountinghub 28 can be a part that is affixed to thecenter shaft 12 or can be molded directly as part of thecenter shaft 12. Thefirst end 24 of each of thesupport legs 22 is connected to the mountinghub 28. Each of thesupport legs 22 connects to the mountinghub 28 with ahinge connection 30 that enables thesupport legs 22 to rotate about the hinge connections between the stowed position and the deployed position. - A
large footpad 32 is attached to thesecond end 26 of each of thesupport legs 22. Thefootpad 32 has aflat bottom plate 34 and ayoke 35 that extends vertically from thebottom plate 34. Theyoke 35 receives thesecond end 26 of asupport leg 22 with apivot connection 37. This enables thefootpads 32 to move in relation to thesupport legs 22, which enables thebottom plates 34 to adjust to an inclined angle, should the standassembly 10 be deployed on an uneven surface. Thebottom plate 34 on eachfootpad 32 is enlarged and has a preferred surface area of between two square inches and eight square inches. This prevents thefootpad 32 from readily sinking into sand or loose soil. - A
slide hub 40 is fitted around thecenter shaft 12. Theslide hub 40 is free to move up and down on thecenter shaft 12 between a first position and a second position. Movement downward to the second position is limited by the presence of the mountinghub 28. At the second position, theslide hub 40 contacts the mountinghub 28 and cannot move beyond the mountinghub 28. Movement of theslide hub 40 to the first position is limited bylinkages 36. Thelinkages 36 attach theslide hub 40 to thesupport legs 22, wherein eachsupport legs 22 is engaged by onelinkage 36. Eachlinkage 36 has afirst end 38 and an oppositesecond end 39. Thefirst end 38 of eachlinkage 36 attaches to theslide hub 40 at ahinge connection 42. Thesecond end 39 of eachlinkage 36 attached to thesupport legs 22. Thelinkages 36 engage thesupport legs 22 near mid-points atpivot connections 44. When theslide hub 40 is moved up thecenter shaft 12, thelinkages 36 lift thesupport legs 22 to their fully stowed positions. Likewise, when theslide hub 40 is moved down thecenter shaft 12, thelinkages 36 unfold thesupport legs 22 to their fully deployed positions. - The
support legs 22 can be locked into both their stowed positions and their deployed positions. Alocking mechanism 46 is affixed to theslide hub 40 and moves with theslide hub 40. Thelocking mechanism 46 is manually operated and can be used to lock theslide hub 40 in place at any point along its range of movement. This enables theslide hub 40 to be locked in place on theshaft 12 both when thesupport legs 22 are fully stowed and when thesupport legs 22 are fully deployed. It also enables theslide hub 40 to be locked in an unusual position, should thesupport legs 22 be deployed on uneven ground. - Referring to
FIG. 3 in conjunction withFIG. 1 andFIG. 2 , it can be seen that to utilize the invention, thestand assembly 10 is carried to a location in its stowed configuration. Thestand assembly 10 is placed on the ground and theauger 20 is turned into the ground. Theauger 20 is rotated by rotating thecenter shaft 12 using the locking handles 15 and/or the foldedsupport legs 22 as handles. This provides good gripping surfaces and a large amount of torque. Consequently, theauger 20 can be driven into packed sand or firm soil by most people. Theauger 20 is driven into the ground until the mountinghub 28 descends to ground level. - Once the
auger 20 is set, theslide hub 40 is unlocked from its first position and lowered along thecenter shaft 12 toward its second position. This causes thesupport legs 22 to rotate down to their deployed positions. Theslide hub 40 is then locked in place on theshaft 12 at its second position with thesupport legs 22 in their extended positions. Thefootpads 32 contact the sand and are biased against the sand by the pull of theauger 20. This creates a very strong and stable support that is not easily displaced by wind forces or incidental contact. An umbrella pole, fishing pole or the like can then be set into the openfirst end 13 of thecenter shaft 12. - Referring to
FIG. 4 , an alternate embodiment of the invention is shown, wherein thestand assembly 10 ofFIG. 1 throughFIG. 4 is integrated into theshaft 51 of abeach umbrella assembly 52. - It will be understood that the embodiments of the present invention that are illustrated and described are merely exemplary and that a person skilled in the art can make many variations to those embodiments. All such embodiments are intended to be included within the scope of the present invention as defined by the appended claims.
