Then the boss 26 is moved in a connecting (first) direction generally parallel with the longitudinal axis LA of the shaft 12 to insert the boss into the socket 40 to the self-retaining position with respect to the lip 40 B. The boss 26 resists passing the lip 40 B until sufficient force is applied in the first direction to cause the boss to deform from its at rest configuration to reduce the width of the boss. When sufficient force is applied, the boss 26 automatically deforms in response to engagement with the lip 40 B, and moves to its retained position. The boss 26 is then obstructed from removal from the socket 40 by the lip 40 B.

- the connected stakes can be turned at any orientation, dropped, or otherwise subjected to incidental forces without becoming disconnected.
- the stakes are disconnected from each other by forcing the bosses 26 out of the sockets 40 .
- a user applies force to the stakes tending to move the boss 26 in a disconnecting (second) direction opposite the connecting direction.
- the boss 26 initially resists deforming until sufficient force is applied to cause the boss to deform to pass the lip 40 B, which permits the stakes 10 to be readily separated from each other. This process is repeated until all of the stakes are disconnected.
- releasable mounting connections can be used without departing from the scope of the present invention.

- the head 114 is formed separately from the shaft 112 .
- the head 114 can be formed of plastic, and the shaft 112 can be formed of metal. Other suitable materials can be used.
- the shaft 112 is part of a peg or nail 162 and is received through an opening 164 in the head 114 .

Abstract
Description
- The present disclosure generally relates to tie down stakes, and more particularly to tie down stakes configured to interface with each other to form a storage configuration.
- Various types of tie down stakes are used for securing structures to the ground or other surfaces. For example, tie down stakes are used for securing structures such as tents, tarpaulins, canopies, signs, cables, straps, etc. to the ground. When driven into the ground, the stakes act as an anchor for securing the structure to the ground. When not in use, such stakes are commonly stored loose in a bag or pouch.
- In one aspect, a set of tie down stakes includes a first tie down stake and a second tie down stake. The first tie down stake includes a first elongate shaft having a proximal end portion, a distal end portion, and a longitudinal axis extending therebetween. The distal end portion is configured to be driven into a surface. A first head on the proximal end portion of the first shaft is configured to secure a first structure segment in position with respect to the surface. The second tie down stake includes a second elongate shaft having a proximal end portion, a distal end portion, and a longitudinal axis extending therebetween. The distal end portion is configured to be driven into the surface. A second head on the proximal end portion of the second shaft is configured to secure a second structure segment in position with respect to the surface. The first tie down stake and the second tie down stake each comprise mounting structure shaped to interface with each other to form a releasable, self-retaining mounting connection to mount the first tie down stake on the second tie down stake in a storage configuration.
- In another aspect, a first tie down stake is stowable with a second tie down stake and a third tie down stake. The first tie down stake includes an elongate shaft having a proximal end portion and a distal end portion. The distal end portion is configured to be driven into a surface. A head on the proximal end portion of the shaft is configured to receive a cord to secure a first structure segment in position with respect to the surface. The head includes a protrusion configured to form a releasable, self-retaining mounting connection with a retainer of the second tie down stake to mount the first tie down stake on the second tie down stake for storage. The head includes a protrusion configured to form a releasable, self-retaining mounting connection with a retainer of the third tie down stake to mount the third tie down stake on the first tie down stake for storage.
- In yet another aspect, a method is for storing tie down stakes. The method includes releasably mounting a first tie down stake on a second tie down stake by inserting a protrusion of the first tie down stake in a socket of the second tie down stake.

- Referring to
FIGS. 1 and 2 , a tie down stake embodying aspects of the present invention is designated generally by thereference number 10. As explained in further detail below, the tie downstake 10 is configured to be driven into the ground to secure a structure in position with respect to the ground. For example, the tie downstake 10 can be used to anchor or tether a tent, tarpaulin, canopy, sign, strap, cord, or other structure to the ground. Multiple tie downstakes 10 may be used to anchor multiple segments of the structure or segments of different structures to the ground or another surface or surfaces. - The tie down
stake 10 generally includes ashaft 12 and ahead 14 on the shaft. Theshaft 12 is configured to be driven into the ground, and thehead 14 is configured to connect to the structure to be anchored by thestake 10. In the embodiment illustrated inFIGS. 1-4 , thehead 14 is integrally formed with theshaft 12. For example, thestake 10 can be formed of one piece of plastic or other suitable material. Other configurations can be used without departing form the scope of the present invention. - Referring to
FIGS. 1 and 2 , theshaft 12 has an elongate shape and includes a proximal end portion secured to thehead 14 and a distal end portion opposite the proximal end portion. Theshaft 12 has a length and longitudinal axis LA extending between the proximal and distal end portions. Theshaft 12 can have any suitable length, such as a length in the inclusive range of 4 to 12 inches. The distal end portion includes a pointed tip configured to enter the ground. Theshaft 12 has an intermediate section between the proximal end portion and the distal end portion. The distal end portion tapers distally from the intermediate section to the tip. The intermediate section has a generally constant width along its length and a T-shaped transverse cross-sectional shape that facilitates being driven into the ground. Theshaft 12 includes an elongatemain body 12A and anelongate flange 12B extending normal to the main body. Themain body 12A and theflange 12B provide the shaft with its T-shaped transverse cross-sectional shape.Barbs 12C extend from opposite sides of theflange 12B to resist removal of the stake from the ground. Shafts having other configurations can be used without departing from the scope of the present invention. - In the illustrated embodiment, the
head 14 includes a generallyflat impact surface 20 against which the head is configured to receive one or more impacts to drive theshaft 12 into the ground. For example, a driving tool such as a hammer can be used to strike theimpact surface 20 to drive theshaft 12 into the ground. Alternatively, a user may be able to push theshaft 12 into the ground by hand without striking theimpact surface 20. In other embodiments, the shaft can be configured to be driven into the ground by rotation or other means. - The
head 14 is configured to connect the tie downstake 10 to a structure to be anchored to the ground. In the illustrated embodiment, thehead 14 includes a protrusion in the form of ahook 22 on which the structure can be held for connecting the structure to thestake 10. For example, thehook 22 can hold a tie such as a strap, cord, etc., which may itself be the structure to be anchored to the ground, or which may connect the stake to another structure (e.g., tent, canopy, tarpaulin, etc.) to be anchored to the ground. Alternatively, thehook 22 can be received in a grommet or other opening of the structure to be anchored. Many other arrangements are possible. Thehook 22 includes anarm 24 and a boss 26 (broadly, “mounting structure”). Thearm 24 has afirst section 24A extending laterally from the proximal end portion of theshaft 12 and asecond section 24B extending distally from the first section toward the distal end portion of the shaft. Theboss 26 is secured to thesecond section 24B at the distal end of thearm 24. Theboss 26 is provided in the form of a ball and may be referred to as a detent, for reasons which will become apparent. Thehook 22 andshaft 12 define agap 30 therebetween in which the structure to be anchored can be received. Other types of protrusions can be used without departing from the scope of the present invention. - It will be appreciated that a set of tie down
stakes 10 can include two, three, four, or more tie down stakes. A set of two tie down stakes 10 is shown inFIGS. 3 and 4 . When the tie downstakes 10 are not in use, the tie down stakes can be stored together by mounting the tie down takes on each other to form a chain of tie down stakes in which releasable mountingconnections 34 are made between adjacent tie down stakes in the chain. Eachstake 10 is configured to connect to at least one other stake in a storage configuration. In the illustrated embodiment, each tie downstake 10 is configured to interface with two tie down stakes to form tworeleasable mounting connections 34. Eachstake 10 includes a retainer 40 (broadly, “mounting structure”) that can be interfaced with thehook 22 of another stake to form a first releasable, self-retainingmounting connection 34, and each stake includes thehook 22 that can be interfaced with theretainer 40 of another stake to form a second releasable mounting connection (not shown). One suchreleasable mounting connection 34 is shown inFIGS. 3 and 4 . It will be readily apparent to a person of ordinary skill in the art that an infinite number of mounting connections may be formed in the same way as mountingconnection 34. - In the illustrated embodiment, the
retainer 40 is provided in the form of a socket in which the hook 22 (broadly, “protrusion”) of anotherstake 10 is receivable. Referring toFIG. 4 , thesocket 40 includes apassage 40A having an inlet at theimpact surface 20 of thehead 14 and an outlet downstream from the inlet. The inlet faces upward away from the distal end portion of theshaft 12. Downstream from the inlet, the socket includes alip 40B extending around thepassage 40A at the outlet. Thelip 40B protrudes inwardly relative to the passage side wall and defines a round opening having a reduced width through which theboss 26 is movable. The illustratedlip 40B is a continuous bead or rib extending inward relative to the wall of thepassage 40A. Thepassage 40A opens to arecess 40C in thehead 14 past thelip 40B. Therecess 40C opens out of opposite sides of thehead 14. Sockets having other configurations can be used without departing from the scope of the present invention. For example, retainers having other retaining structures (e.g., lips having other configurations, etc.) can be used. The lip does not need to be continuous around the passage or be arcuate or round. - The
boss 26 is sized to be freely slidable in thepassage 40A from the inlet to thelip 40B and to engage thelip 40B to retain the boss in thesocket 40. Referring toFIG. 4 , theboss 26 has a width W1 slightly less than a width W2 of the passage from the inlet to thelip 40B, permitting the boss to freely slide from the inlet to the lip. The width W1 of theboss 26 is slightly greater than the width W3 of thepassage 40A at thelip 40B. Theboss 26 includes afirst section 26A and asecond section 26B separated by agap 26C. The first andsecond sections boss 26 have rounded outer surfaces and are resiliently deflectable toward each other to decrease thegap 26C such that the boss defines a resiliently deformable ball shaped connector. Theboss 26 is sized to engage thelip 40B to cause the boss to resiliently deform from an at rest configuration to decrease the width of the boss. As the rounded or tapered outer surfaces of the first andsecond boss sections lip 40B, the first and second sections progressively move closer to each other, reducing the width of thegap 26C. Thegap 26C extends from a distal end of the boss toward a proximal end of the boss beyond an intermediate portion of the boss where the boss has its maximum width W1. After the intermediate portion of theboss 26 passes thelip 40B, the boss resiliently expands (e.g., completely or partially to its previous at rest configuration) and assumes a self-retaining position in thesocket 40. Theboss 26 forms an interference fit with thelip 40B to retain the boss in thesocket 40. The connection of theboss 26 in thesocket 40 may also be referred to as a ball and socket connection and/or a detent arrangement. Moreover, the connection can be referred to as a “snap” connection in which the boss snaps into releasable mounted position in the socket. Other types of releasable mounting connections can be used without departing from the scope of the present invention. For example, other types of interference fits, detent arrangements, and/or snap connections can be used. - It will be appreciated that
multiple stakes 10, such as three, four, five, six, etc. stakes can be chained together by forming releasable mountingconnections 34 to form a chain of stakes in which all of theshafts 12 are generally parallel to each other and longitudinally offset from one another. As shown inFIGS. 3 and 4 , when twostakes 10 are in the storage configuration (forming the releasable mounting connection 34), theshafts 12 of the stakes extend generally alongside each other and are longitudinally offset from one another. The releasable mountingconnection 34 is configured to maintain thestakes 10 in this general orientation. It will be appreciated that pivoting the longitudinal axis LA of onestake 10 relative to the longitudinal axis of the other stake is limited by engagement of theprotrusion 22 in thesocket 40 and by engagement of theshafts 12 against each other. In particular, when theboss 26 is in the retained position in thesocket 40, engagement of thearm 24 against surfaces of thepassage 40A prevents substantial pivoting of the longitudinal axes LA of thestakes 10 with respect to each other about thereleasable mounting connection 34. Thehead 14 of the mounted tie downstake 10 may also engage the other tie down stake under the mountingarm 24 to further limit movement of the tie down stakes with respect to one another. Desirably, the arrangement is such that when the tie downstakes 10 are in the storage configuration, the tie down stakes are nested together and supported against substantial rotation with respect to one another. The releasable mountingconnection 34 is desirably a substantially rigid connection but may permit some movement of thestakes 10. For example, the releasable mountingconnection 34 may be configured to prevent rotation of a longitudinal axis LA of one stake to form and angle greater than about 10 degrees, 15 degrees, 20 degrees, 25 degrees, 30 degrees, 35 degrees, or 40 degrees from parallel with the longitudinal axis LA of the other stake. In other words, the releasable mountingconnection 34 may be configured to maintain the longitudinal axes LA of theshafts 12 oriented with respect to each other between parallel and about 10 degrees off parallel, between parallel and about 20 degrees off parallel, between parallel and about 25 degrees off parallel, between parallel and about 30 degrees off parallel, between parallel and about 35 degrees off parallel, or between parallel and about 40 degrees off parallel. - In a method of using the tie down
stakes 10, the tie down stakes can be driven into the ground or another surface where it is desired to anchor a structure.Multiple stakes 10 can be used to anchor multiple segments of the structure or anchor different structures. When thestakes 10 are no longer needed, the stakes can be removed from the ground and arranged in the storage configuration. Afirst stake 10 is mounted on asecond stake 10 by inserting thehook 22 of the first stake in thesocket 40 of the second stake. A third stake (not shown) is mounted on thefirst stake 10 by inserting the hook of the third stake in thesocket 40 of the first stake. The process can be repeated as many times as needed to chain all of thestakes 10 of a set together. To form each releasable mountingconnection 34, theshafts 12 of the two stakes are arranged alongside each other with theboss 26 adjacent the inlet of therespective socket 40. Then theboss 26 is moved in a connecting (first) direction generally parallel with the longitudinal axis LA of theshaft 12 to insert the boss into thesocket 40 to the self-retaining position with respect to thelip 40B. Theboss 26 resists passing thelip 40B until sufficient force is applied in the first direction to cause the boss to deform from its at rest configuration to reduce the width of the boss. When sufficient force is applied, theboss 26 automatically deforms in response to engagement with thelip 40B, and moves to its retained position. Theboss 26 is then obstructed from removal from thesocket 40 by thelip 40B. The detent arrangement of theboss 26 in thesocket 40 resists release of the releasable mountingconnection 34. Theprotrusion 22 and retainer 40 (broadly, “connectors”) are integrally formed with and carried by thestakes 10 so no additional components are needed to secure the stakes to each other in the storage configuration. Thestakes 10 are conveniently held together as a group by releasable, self-retainingconnections 34 formed by the stakes themselves. Thus, the connected stakes can be turned at any orientation, dropped, or otherwise subjected to incidental forces without becoming disconnected. When it is desired to use thestakes 10 again, the stakes are disconnected from each other by forcing thebosses 26 out of thesockets 40. A user applies force to the stakes tending to move theboss 26 in a disconnecting (second) direction opposite the connecting direction. Theboss 26 initially resists deforming until sufficient force is applied to cause the boss to deform to pass thelip 40B, which permits thestakes 10 to be readily separated from each other. This process is repeated until all of the stakes are disconnected. - Other types of releasable mounting connections can be used without departing from the scope of the present invention. For example, other types of protrusions and other types of retainers can be used, and the connection need not include a deformable connector. Moreover, instead of the protrusion being deformable for forming the releasable mounting connection, the retainer can be deformable, or the protrusion and retainer can be deformable.
- Referring to
FIGS. 5-7 , a second embodiment of a tie down stake is designated generally by thereference number 110. The tie downstake 110 is similar to the tie downstake 10 of the first embodiment, and similar parts are designated by similar reference numbers, plus 100. For example, the tie downstake 110 includes anelongate shaft 112 and ahead 114 secured to the shaft. In this embodiment, thehead 114 is formed separately from theshaft 112. Thehead 114 can be formed of plastic, and theshaft 112 can be formed of metal. Other suitable materials can be used. In this embodiment, theshaft 112 is part of a peg ornail 162 and is received through anopening 164 in thehead 114. Thepeg 162 includes ahead 162A that abuts thestake head 114 around an edge margin of theopening 164 to locate theshaft 112 with respect to thestake head 114. Theopening 164 may also be sized to provide a friction fit of theshaft 112 in the opening. - As in the first embodiment, the
stake 110 of this embodiment is configured to form releasable mountingconnections 134 with other stakes for storage. Twostakes 110 are shown connected to each other inFIGS. 6 and 7 . Eachstake 110 includes a protrusion in the form of ahook 122 including anarm 124 and a resilientlydeformable boss 126. Eachstake 110 also includes a retainer in the form of asocket 140 including apassage 140A and alip 140B in the passage. In this embodiment, thehead 114 does not define a recess downstream from thelip 140B. Instead, theboss 126 protrudes beneath thehead 114 when in the retained position. Moreover, thesocket 140 is not formed in the impact surface at thestake 110. Instead, thesocket 140 is formed in part of thehead 114 next to the impact surface, and part of theshaft 112 forms the impact surface. Formation of the releasable, self-retainingmounting connection 134 is performed in the same method as described above with respect to the first embodiment. The engagement of theheads 114 against each other (e.g.,boss 126 againstlip 140B,arm 124 against wall ofpassage 140A, etc.) maintains thestakes 110 in a storage configuration in which theshafts 112 extend generally alongside each other and are longitudinally offset with respect to each other. - It will be apparent that modifications and variations are possible without departing from the scope of the invention defined in the appended claims.
- As various changes could be made in the above constructions and methods without departing from the scope of the invention, it is intended that all matter contained in the above description and shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
