Real Estate agents dread the process and logistics of placing directional signs, for example signs indicating Open Houses. These signs are customarily held up on metal stakes which are driven into the ground, and are transported in the Real Estate agent's car to the site. The task of placing these signs requires managing an array of varying sized stakes, often ranging from short (e.g. 29″) light weight stakes to tall (e.g. 49″) heavy duty stakes, since it is never known which size stake will end up being best suited for the desired location. Accommodating the tall stakes often requires the realtor to fold down a passenger seat and shift other surrounding contents in the car in order to fit in the stakes in the trunk or cargo area. This both takes additional time as well as decreases the number of people the car can accommodate. Furthermore, the unique angles and points of the various stakes inevitably get tangled together. As such, the process of finding and setting up the correct stake is time consuming. Moreover, there is always the looming risk of having the numerous oversized sharp stakes puncture or scratch something in the vehicle that would be very expensive to fix or replace. Retrieving stakes that are tangled together can become a tug of war, further adding risk for potential car damage.
Realtors are forced to choose between preset heights of stakes, as well. Currently “adjustable” stakes are provided with preset holes at varying heights which a realtor must manually affix with a bolt and nut. The height and orientation of such a stake is regulated by the preset spacing of the holes, thereby limiting the realtor's ability to adjust the stake to the optimum height or orientation. The process of manually adjusting such a stake is also time consuming, which is a disadvantage when trying to quickly place each directional sign.
In addition, the viewing positions of the current one-dimensional stakes are limited to the precise placement and footprint in which the realtor can physically insert the spikes into the ground, often forcing the agent to bend the stake prongs to align the sign for optimal viewing, risking breakage of the stakes in the process.
It is therefore a primary object of the present invention to provide a system and method which improves upon prior art stakes and methodologies and their related drawbacks as described above.
Additional features and utilities of the present general inventive concept will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the general inventive concept.
The foregoing and/or other features and utilities of the present general inventive concept may be achieved by providing an adjustable stake, including a lower pole including a hollow sleeve, an upper pole configured to be inserted into the hollow sleeve coaxially with the lower pole and to rotate freely therein through a 360 degree arc, and a fixing unit disposed on the lower pole to hold the upper pole stationary with respect to the lower pole.
In an exemplary embodiment, the lower pole includes a primary spike configured to be driven into a surface, the primary spike being coaxial with the lower pole.

Thus, the terms used herein are defined based on the intended meaning of the terms together with the description throughout the specification.
Also, when a part “includes” or “comprises” an element, unless there is a particular description contrary thereto, the part can further include other elements, not excluding the other elements.
Hereinafter, one or more exemplary embodiments of the present general inventive concept will be described in detail with reference to accompanying drawings.
As illustrated in
The terms “upper” and “lower” are used herein for convenience of description, with reference to the relative positions of the components when the stake is driven into a surface, e.g., the ground. Accordingly, a “lower” pole or “lower” end is closer to the ground than the corresponding “upper” pole or end when the stake 100 is driven into the ground.
The stake 100 described herein may also include an ID tag 50 (illustrated in
The exemplary embodiment of the ID tag 50 illustrated in
The stake 100 is preferably made of one or more corrosion-resistant materials, such as, for example, powder-coated steel, galvanized steel, stainless steel, and/or plastic. According to an exemplary embodiment of the present general inventive concept, the upper pole 10 may be made of powder-coated steel, the lower pole 20 may be made of galvanized steel, and the fixing device 30 may include, for example, a plastic knob which is attached to a stainless steel screw. Hole 27, illustrated in
In an exemplary embodiment of the present general inventive concept, the stake 100 may be a pole-and-sleeve arrangement in which at least one of the upper pole 10 and lower pole 20 includes a hollow portion which may accommodate the other pole, such that the two poles 10 and 20 are coaxial with respect to each other. For example, the upper pole 10 may be inserted into a hollow sleeve 25 of the lower pole 20, so that the upper pole 10 and lower pole 20 may move relative to one another. It will be understood that any similar configuration may also be used according to the present general inventive concept. For example, the lower pole 20 may instead be inserted into the upper pole 10. Furthermore, the present general inventive concept is not limited to a pole-and-sleeve arrangement. For example, the upper pole 10 and lower pole 20 may be positioned alongside and parallel to each other and held together with the fixing device 30.
Exemplary embodiments of the upper pole 10 are illustrated in detail in
As illustrated in
Exemplary embodiments of the lower pole 20, which may also be called the lower base, are illustrated in detail in
As illustrated for example in
The primary spike 21 and any secondary spikes 23 may have any shape suitable to be driven into a surface, e.g. soil or similar material, to support the stake 100. This may be, e.g., a sharp metal tip, an auger tip, a half spade tip, and so on. A half spade tip, illustrated for example in
As noted above, the lower pole 20 may further include a hollow sleeve 25 suitable to receive the upper pole 10. The sleeve 25 may extend through the length of the lower pole 20. In the exemplary embodiments of the present general inventive concept illustrated in the cross-sectional views of
As illustrated in
In an exemplary embodiment of the present general inventive concept, the nesting area 26 may accommodate the prong bar 11 of the upper pole 10. This nesting area 26 may securely hold the prong bar 11 in place while the stake 100 is collapsed to its shortest height, thereby keeping the upper pole 10 from rotating relative to the lower pole 20. The nesting area 24 is preferably configured to hold the stake 100 in a substantially flat configuration while the stake 100 is fully collapsed. For example, if the lower end of the lower pole 20 includes one or more horizontal arms 24 supporting one or more secondary spikes 23, the notch or groove of the nesting area 26 may be parallel to these arms 24, so that the prong bar 11 and holding portion 12 of the upper pole 10 are held parallel to the arm(s) 24 and the stake 100 may therefore lie flat while fully collapsed. Exemplary embodiments of the collapsed state of the stake 100 are illustrated in
The nesting area 26 may be any size suited to the purposes described herein. The nesting area 26 may be for example 0.25″ deep, such that the prong bar 11 nests 0.125″ within the nesting area. Furthermore, as illustrated in
The upper pole 10 may have a length of, e.g., 28″ including the holding portion 12, and the lower pole 20 may have a length of, e.g., 23″ including the primary spike 21 and any secondary spikes 23. If the lower pole 20 includes both a sleeve 25 and a hollow portion 22 of a primary spike 21, the sleeve 25 and hollow portion 22 may have a total combined length of, e.g., 21.875″. However, it will be understood that these lengths may be adjusted according to the specific application of the stake 100, and still provide the intended applications described herein. In an exemplary embodiment of the present general inventive concept, the lengths of the upper and lower poles 10 and 20 are such that when the upper pole 10 is fully inserted into the hollow sleeve 25 of the lower pole, a lower end of the upper pole 10 rests on the bottom of sleeve 25 or hollow portion 22, while the prong bar 11 of the upper pole 10 rests in the nesting area 26, as illustrated for example in
Exemplary embodiments of the fixing device 30 are illustrated in detail in
According to the exemplary embodiment of the present general inventive concept illustrated in
The upper pole 10 may have a circular or polygonal cross-section, as illustrated in
As illustrated for example in
The lower pole 20 may further include a foot pad 28 configured to be struck, e.g. with a mallet or a user's foot, to drive the stake 100 into the ground. The foot pad 28 may be included at, for example, a portion of the lower pole 20 near the primary spike 21, to allow a user to more easily put their foot on the foot pad 28.
In an exemplary embodiment of the present general inventive concept, the foot pad 28 may be integrated with the primary spike 21. See for example
According to an exemplary embodiment of the present general inventive concept, if the lower pole 20 includes one or more secondary spikes 23, a horizontal arm 24 supporting one of the spikes 23 could include the foot pad 28 to help drive the lower pole 20 into the ground.
The foot pad 28 may be relatively small, e.g., 1 square inch, to accommodate a tool such as a mallet's head, or the foot pad 28 may be relatively long, for example 0.25″ by 3.5″, to accommodate a user's foot. Other options may include a combined long and wide style, for example 2″ by 3″.
Since the stake 100 may be adjusted in height, there is no longer a need for Real Estate agents and other users to carry multiple different sizes of stakes when setting up directional signs. Users may carry any number of stakes 100 according to the present general inventive concept and adjust each stake as necessary. Furthermore, the stake 100 may be compacted down to its minimum height to be easily stored, for example to fit into any car's trunk. This compacting feature may minimize damage to the vehicle or its contents (scratches, punctures, etc.), as well as entanglement with other stakes 100. Furthermore, the compact size allows users to place the stakes in their vehicle without the need to fold down any passenger seats and shift around surrounding items to accommodate the stakes, making for a tidy and organized car friendly environment.
Since the upper pole 10 can be freely rotated relative to the lower pole 20, even after the stake 100 is positioned (e.g., driven into the ground), the upper pole 10, which may be carrying a sign for example, can still be adjusted for optimum position and visibility of a sign. This may be useful, for example, if the sign includes a directional indicator such as an arrow. By rotating the upper pole 10 after placement, such a directional indicator can be oriented quickly and precisely without having to remove and reposition the stake in the ground.
Furthermore, the upper pole 10 and lower pole 20 may be separable from each other, for example by loosening or removing the fixing device 30 which holds them together. Separated upper and lower poles 10 and 20 may reduce tangled storage and facilitate easy retrieval of the stake 100. For example, the upper pole 10 and lower pole 20 may be stored so that the points of the spikes 21 and 23 are aligned with the holding portion 12, to help keep multiple stakes 100 from getting tangled together. The multi-piece design also allows for easy replacement in the event one part breaks.
Although
As illustrated in
As illustrated in
Alternatively, the strike plate 15 may be omitted, and instead the strike point 14 of the upper pole 10 may left exposed to be struck with, e.g., a mallet if necessary to drive the stake 100 into the ground. If the strike plate 15 is omitted, the removable ID tag 50 may be attached to the stake 100 after the stake 100 is driven into the ground. The ID tag 50 may be attached to the strike point 14, both to hide the strike point 14 and also to identify the owner of the stake 100.
According to an exemplary embodiment of the present general inventive concept, a lower end of the upper pole 10 does not reach to the bottom of the sleeve 25 when the stake 100 is collapsed. In an alternative exemplary embodiment, the lower end of the upper pole 10 may be in contact with or partially inserted into the primary spike 21 at the bottom of the lower pole 20 while the stake 100 is collapsed. This collapsed state may give the stake 100 a solid construction, thereby allowing a user to more easily drive the stake 100 into the ground without damaging the stake 100 in the process. Accordingly, a user may drive the collapsed stake 100 into the ground with a mallet, for example by striking the strike point 14 or strike plate 15 at the center of the upper pole 10. If the upper pole 10 is in contact with or partially inserted into the primary spike 21, the impact force from the mallet on the upper pole 10, e.g. on the strike point 14 or strike plate 15, may be transferred through the upper pole 10 to the spike 21 at the bottom of the lower pole 20. This transfer of force may drive the stake 100 into the ground without damaging the stake 100.
Furthermore, in exemplary embodiments of the lower pole 20 including a foot pad 28, the foot pad 28 may serve a similar purpose as the strike point 14. That is, the foot pad 28 is configured to receive force from a tool (such as, e.g., a mallet) instead of a user's foot. In an exemplary embodiment of the present general inventive concept in which the foot pad 28 is configured to be struck with a tool, e.g., a mallet, the foot pad 28 may be placed near the upper end of the lower pole 20, to allow a user to more easily strike the foot pad 28 with the tool.
Furthermore, the upper pole 10 and lower pole 20 of the stake 100 may be modular and interchangeable, thereby enabling variable configurations of the stake 100. For example,
As illustrated in
Furthermore, although the examples described above are of a single-stake design in which the upper pole 10 is parallel or coaxial to the lower pole 20, effectively forming one pole while the stake 100 is assembled, the present general inventive concept is not limited merely to this configuration. For example, two stakes 100, including holding devices 12 which can each hold up one end of a sign, may be used to hold up opposite ends of a sign. In this example, since both stakes 100 are adjustable in both height and rotational angle of the upper pole 10, it becomes relatively simple to align the stakes 100 to support a large sign between them.
Additionally, the lower pole 20 is not limited to only using spikes 21 and 23. The lower pole 20 may have any form suited to supporting the stake 100. For example, in place of spikes 21 and 23, the lower pole may include an optional water/sand filled base or an A-frame stand, which may support the stake 100 on concrete or other surfaces that a spike 21 or 23 cannot be driven through.
Still further, the present general inventive concept is not limited only to supporting signs. In another exemplary embodiment, the upper pole 10 and lower pole 20 may function as an adjustable garden stake to support a trellis instead of a sign, thereby serving, for example, the Home and Garden Industry for growing plants. The specific configuration of the stake 100 may be modified depending on the application. For example, if the stake 100 is being used to support growing vegetation (plants) or a trellis, the holding device 12 of the upper pole 10, or alternatively the fixing device 30 of the stake 100, may include, e.g., a clamp or other fastener to secure a plant or a trellis to the stake.
Still further, although the stake 100 presented herein is of particular use to realtors in displaying, e.g., Open House signs, it is not limited thereto, and may be used to support any manner of signs. For example, a stake 100 according to the present general inventive concept may support garage sale signs, political propaganda, or other signs which benefit from a stake that puts the sign at maximum visibility.
In an exemplary embodiment of the present general inventive concept including an upper pole 10 inserted into a hollow lower pole 20, the stake 100 may be positioned, for example driven into the ground, by any of the methods described above. Once the stake 100 is securely positioned, for example by having primary spike 21 and optionally secondary spikes 23 on the lower pole 20 driven into the ground, the upper pole 10 may then be adjusted relative to the lower pole 20 to achieve the optimum viewing position. For example, the user may loosen the fixing device 30 and slide the upper pole 10 up from the collapsed position to extend the stake 100 to a desired height. The upper pole 10 may also be rotated in order to achieve an optimum viewing angle of a sign mounted on the upper pole 10. Once adjusted in this manner, the upper pole 10 and lower pole 20 may be secured relative to one another, for example by tightening the fixing device 30, so that the stake 100 may remain in the adjusted configuration.
