The present disclosure is directed to an improved landscaping stake and driver. More specifically, the present disclosure is directed to a landscaping stake and driver with an improved means for driving the landscaping stake into the ground.
Landscapers often utilizing stakes to hold landscaping structures such as edging to the ground. Such edging is often formed of pliable strips of material that separate areas of landscaping. For instance, edging is often used to separate lawns from planting beds. Landscaping stakes typically engage a portion of the landscape edging and secure it in place. For example, several stakes are positioned along the length of the edging and driven into the ground to secure the edging in a desired location. In some instances fasters are required to secure the edging to the stake. A commonly utilized landscaping stake is a u-shaped wire that extends over lawn edging and is pounded into the ground.
Inserting the stake into the ground to its proper depth may result in damage to the stake and/or edging. Typically, the stakes are pounded directly with a hammer until the stake engages the top of the edging. However, during this process the hammer can cause damage to the stake, especially when the ground is hard. That is, the process of driving the stake into the ground deforms the stake. Additionally, it is difficult to control the force applied when pounding the stake to adequately secure the edging. That, in attempting to ensure the stake securely engages the edging, excess pounding can result in damage to the edging and/or stake.
Disclosed herein is a landscaping stake and related driver. Generally, the landscaping stake is directed to a stake that may be configured into a U-shape and driven into the ground to secure landscaping elements such as edging. The stake has elongated legs having a contoured profile in cross-section which makes the legs very resistant to deformation permitting the landscaping stake to be driven into hard surfaces. The driver is configured to releasably engage the upper and of the landscaping stake. The driver spreads impact forces to the legs of the landscaping stake preventing damage to the stake while it is being driven into the ground.
According to a first aspect, a landscaping stake is provided. The landscaping stake has first and second elongated legs connected by a joint. Each of the elongated legs includes a concave/convex cross-sectional profile over at least a portion of its length. The concave/convex profile adds significant rigidity to the legs allowing the state to be driven into hard surfaces. Further, each leg includes a pointed tip on its free end and a plurality is serrated elements formed along at least a portion of the length of the legs. The serrated elements resist removal of the stake once stake is driven into the ground. The joint is deformable to allow positioning of the first and second legs and desired orientation relative to one another.
In one arrangement, the landscaping stake is formed out of a flat sheet material in a stamping process. In such an arrangement, the legs and joints are integrally formed. Further, the concave/convex profile of the legs may be formed during the stamping process. In one arrangement, the legs each have an inner concave surface and outer convex surface. That is, when the joint is deformed to dispose the legs in a spaced parallel orientation, the concave surfaces of the legs face one another. However, it will be appreciated this configuration may be reversed. In one particular arrangement, each leg has a V-shaped or L-shaped cross-sectional profile over at least a portion of its length. Other profiles may be utilized. For instance, a W-shaped cross-sectional profile may be utilized. What is important is that each leg include one or more bends or ribs that runs axially along its length to provide in improved structural rigidity.
The serrations may have any appropriate configuration. Typically, the serrations are formed on the edges of the elongated legs over a portion of the legs proximate to their tips. In one arrangement, the serrations have a sawtooth configuration having a forward edge angled from the tip toward the connecting joint. Rearward edges of the seriation are transverse to a central axis of each leg. This configuration resists removal once the stake is driven into the ground.
In one arrangement, the landscaping stake includes shoulder surfaces at the transitions between the joint and the concave/convex cross-sectional profiles of the legs. Generally, the shoulder surface is an angled surface relative to the centerline axis of the stake when the legs are disposed in a spaced parallel relationship (U-shaped configuration). This angled surface extends between the generally flat joint (e.g., in cross-sectional profile) and the contoured profile of the legs. The angled surfaces or shoulders provide a location to which driving forces may be applied in addition to the joint. That is, each leg may be driven directly into the ground.
According to another aspect, a driver is provided for driving a landscaping stake into the ground. The driver includes a generally U-shaped body having a driving surface formed on the outside surface of the closed end of the body. An inner surface of the U-shaped body is conformably shaped to the outside surface of a landscaping stake. The inner surface includes a slot section that receives a joint of a landscaping stake. In one arrangement, the slot section includes first and second spaced parallel sidewalls and a closed end. The spacing between the sidewalls allows for insertion of a joint of a landscaping stake there between. The inside surfaces of the legs (e.g., lower sections) of the U-shaped body attach to the lower ends of the slot sidewalls and flare outwards. More specifically, the lower sections angle outward from centerline axis of the driver at an angle that is substantially identical to angled surfaces toward the top ends of the legs of the landscaping stake. When placed on the landscaping stake, striking the driving surface results in impact forces being applied to the legs such the legs are driven directly into the ground.
Reference will now be made to the accompanying drawings, which at least assist in illustrating the various pertinent features of the presented inventions. The following description is presented for purposes of illustration and description and is not intended to limit the inventions to the forms disclosed herein. Consequently, variations and modifications commensurate with the following teachings, and skill and knowledge of the relevant art, are within the scope of the presented inventions. The embodiments described herein are further intended to explain the best modes known of practicing the inventions and to enable others skilled in the art to utilize the inventions in such, or other embodiments and with various modifications required by the particular application(s) or use(s) of the presented inventions.
As shown in
In any arrangement, the end section 15 of the legs 12 will have a pointed tip 18. Typically, the end sections 15 of the legs 12 will also have teeth or serrated elements 16 for anchoring the landscaping stake 10 securely in the ground. The serrated elements 16 provide a mechanism to prevent one or more legs 12 of the landscaping stake 10 from being dislodged once driven into the ground.
The closed end or joint 14 connects the legs 12 and the inside surface of the joint interfaces with landscaping elements such as edging 11. See
As shown the joint 14 and legs 12 form a substantially U-shaped element. However, it will be appreciated that the joint 14 could be formed to take on different shapes designed to interface with a differently configured top edge of a landscaping edging 11. For example certain edging 11 may be composed of a long strip of material having a substantially rectangular cross-section transitioning to a circular cross-sectional profile at the top edge. In this regard the joint 14 could be configured to have a complimentary circular side profile to engage with this profile of the edging 11. Embodiments such as these may further aid in securely retaining edging 11 in a desired location. It is also appreciated that, as noted above, the legs 12 may also take on various forms to similarly engage with landscaping edging 11. In this regard the joint 14 could be configured to engage with specific features of a particular edging 11 and the legs 12 could be configured to do the same.
In use, the stake 10 is positioned with a leg on either side of the edging 11. See
In other embodiments the cross-section of the landscaping stake could vary along the length of the stake. For example, the cross-sectional thickness of the joint 14 could be thinner than the cross-sectional thickness of the legs 12. This may provide additional rigidity to the legs 12 when being driven into harder ground or through other landscaping structure such as clay or rocky sections. The thinner joint thickness facilitates easier bending of the joint 14 providing easy orientation of the legs 12 relative to each other. Alternatively, the cross-section of the joint 14 could be thicker than the legs 12. This may be useful in situations where increased strength is required in the joint 14, such as when holding a more heavily weighted section of edging 11 and the legs 12 don't need to be as rigid because they are being driven into softer ground.
In the illustrated embodiment the joint 14 has a relief aperture 28. The aperture 28 may be located at substantially the center of the joint 14 and is illustrated as a circular hole, though other shapes are possible. The aperture 28 facilitates bending of the joint 14 in a desired location by creating a stress concentration at locations of the aperture 28 directly adjacent the edges of the joint 14 when a bending force is applied to the stake.
The landscaping stake may be formed from a single, rectangular piece of stock material having a uniform thickness and width. In such an embodiment, the stake may be formed in a stamping process. In such a process, the cut outs that form the serrations 16 geometry and the aperture 28 are the only scrap removed from a flat sheet of material that is stamped to create the landscaping stake. However, it will be appreciated that other manufacturing techniques such as machining or molding may be selected. After a first stamping operation creating a flat piece with the landscaping stake 10 profile, a second stamping process can be used to form the desired cross-sectional configuration (e.g., v-shaped legs 12) creating the embodiment of the landscaping stake 10 shown in
As shown in
In various embodiments the inner surface 42 of the driver may take on different complimentary shapes to the landscaping stake 10. In one example, where the profile of the legs 12 of the landscaping stake 10 are v-shaped, the inner surface 42 of the lower portions 45 could have a substantially similar or mating v-shaped profile. However, the inner surface 42 of the driver may take on any profile that facilitates receiving a portion of the landscaping stake 10, but is a different shape than the portion of the landscaping stake 10 it receives. For instance, the lower portions 45 of the surface 42 could have a curved cross-sectional profile and be operable to receive a landscaping stake 10 with legs 12 that have a v-shaped cross-sectional profile. However, any configuration will contact the shoulders of the stake to spread impact forces directly to the legs.
In the illustrated embodiment the driver 40 is U-shaped and the sides of the driver are open. The open sides coincide with the space between the two legs 12 and joint 14 of the landscaping stake 10. This configuration allows the driver to remain engaged with a portion of the landscaping stake 10 while it is being driven over a piece of edging disposed between the legs. Further, the length of the driver may be configured to correlate to the height of edging (e.g., less than the height of the edging). In this regard, when the landscaping stake 10 is being driven into the ground using the driver 40, the driver may remain engaged with the stake until the stake engages the top end of the edging.
The driver 40 may be formed from a single piece of material by a process bending and/or stamping. Although it will be appreciated that various other process such as machining or molding could be employed. In a stamping process the driver's 40 outside surface 48 could take on the same cross-sectional shape as the inner surface 42. The driving section 50 facilitates driving the landscaping stake 10 into the ground.
The heavier gauge driver 40 allows receiving a driving force such (e.g., hammer strike) without deforming. That is, the driver 40 has a thicker cross sectional profile than the landscaping stake and is made of rigid materials (e.g., aluminum, steel, plastics, etc.). In some embodiments the driving section 50 may be configured to interface with a specific driving mechanism. For example the driving section 50 may have a keyed shape (not shown) that interfaces with a complimentary interface on a driving mechanism such as a pneumatic stake driver. Further, it will be appreciated that the driving section 50 could be flat to facilitate pounding with a hammer and/or have a thicker cross-section relative to a bottom portion of the driver 40 to provide additional resistance to deformation, bending, or failure.
In other embodiments the driver 40 is assembled from multiple parts, which may be made of the same or different materials. For example, one embodiment has an inner component forming the inner surface 42 made from a plastic material. This inner component interfaces with an outer component forming the outer surface 48 and driving section 50. In this arrangement, the outer component is made from a more rigid material such as a metal or hard plastic. This configuration allows the softer inner component to provide greater cushioning to the landscaping stake 10 and/or edging 11 and facilitates removal of the driver 40 from the landscaping stake 10. The harder outer surface provides increased rigidity to resist deformation when a driving force is applied. It will be appreciated that other combinations of assemblies of multiple subcomponents forming the driver 40 are possible.
Notably, when the driver 40 is positioned on a stake, and the legs 12 of the stake are positioned on opposing sides of a piece of lawn edging (see end view
