[0028] The following relates to convertible trekking poles that provide multiple benefits. Since hikers may desire to carry a minimum of items, convertible trekking poles fulfill more than one purpose.

[0029] Trekking poles are lightweight supports that provide health benefits and stability over rough terrain. Trekking poles make it easier for hikers and climbers to reach mountain summits and traverse valleys, enabling once-in-a-lifetime adventures.

[0030] When exploring outdoors with their trekking poles, hikers often want to capture the magnificent natural landscape about them in photos, videos or other social media. They may be in the company of friends and family, and want memories that they can have together and share with others. They may wish to take photos that include all members of the group. The desire to take photos and leave memories is further compounded by the increasing number of selfie devices, selfie sticks, mobile devices, etc. that enable users to easily take their own photos. In the case of a backpack that holds very few items, hikers may just rely on unstable logs, riverbed rocks or other nearby objects, which cannot provide stable support for expensive cameras and mobile devices. An example of a trekking pole that provides the kind of support needed for photographic affairs and other transportation needs is now described.

[0031] An example improved trekking pole is described. The trekking pole includes a main shaft having an inner cavity. The trekking pole also includes two concentric shafts, which will be removably disposed in the inner cavity of the main shaft. The trekking pole further includes a distal shaft having an inner cavity. The main shaft will be removably disposed in the inner cavity of the distal shaft. In other words, the main shaft can slide in the distal shaft so that the main shaft can be removed from the distal shaft. The trekking pole also includes a housing connected to the main shaft on the inner cavity of the main shaft, the housing receiving the two concentric shafts to form a tripod, the housing including a T-slot to receive an adapter.

[0032] In another example, an improved trekking pole includes a main shaft having a hollow inner cavity. Two concentric shafts are removably disposed in the inner cavity of the main shaft. A distal shaft has an inner cavity. The main shaft is slidably disposed in the inner cavity of the distal shaft. A secondary shaft has a hollow interior that removably receives the distal shaft and the main shaft, and the secondary shaft will be supported by the tip of the distal shaft. A locking member fixes the main shaft at a variable position on the distal shaft, and thus provides a variable length for the trekking pole. For example, the locking member can securely clamp the distal shaft to the main shaft. A housing is coupled to the main shaft on the inner cavity of the main shaft. The housing includes a coupling structure to receive the two concentric shafts to form a tripod. In a first configuration, the two concentric shafts are disposed in the inner cavity to form a trekking pole configuration. In a second configuration, the two concentric shafts are removed from the main shaft and received by the engagement structure of the housing to form a tripod configuration; the retainer will be removably connected to the housing; and the secondary shaft will be removed from the distal shaft and removably connected to the retainer to form a vertical attachment.

[0033] In yet another example, an improved trekking pole includes a main shaft having a hollow inner cavity. A plurality of concentric shafts are disposed in the inner cavity of the main shaft. A distal shaft has an inner cavity, and the main shaft will be slidably disposed in the inner cavity of the distal shaft. A locking member fixes the main shaft at a desired position on the distal shaft, and thus provides a desired length for the trekking pole. A housing is coupled to the main shaft on the inner cavity of the main shaft. The housing includes an engagement structure to receive the plurality of concentric shafts to form a tripod configuration. A handle device is removably coupled to the housing, and the handle device has a hollow interior. In a first configuration, the handle device is coupled to the housing, and the plurality of concentric shafts are disposed in the inner cavity of the main shaft to form a trekking pole configuration. In a second configuration, the handle device is removed from the housing, and the plurality of concentric shafts are received by the engagement structure of the housing to form a tripod configuration. DETAILED DESCRIPTION

[0034] Steering Figure 1 , showing the improved trekking pole 100 in a trekking pole configuration 102, and an arrow pointing to its converted form in a tripod configuration 104. The trekking pole configuration 102 is also referred to herein as a first configuration of the improved trekking pole 100. The tripod configuration 104 is also referred to herein as a second configuration of the improved trekking pole 100.

[0035] In the trekking pole configuration 102, the trekking pole 100 is a generally elongated rod-shaped member including a main shaft 106 and a distal shaft 108 having a tip 112 that is sharp or otherwise defined to contact a ground surface. In some examples, the trekking pole 100 includes a handle device 110 or other gripping structure at one end of the main shaft 106. In some examples, at least one grip 114 may be positioned along the elongated member and configured to be gripped to hold the trekking pole 100. The trekking pole 100 also includes a secondary shaft 116 having a hollow interior that removably receives the distal shaft 108 and the main shaft 106. When in the trekking pole configuration 102, the secondary shaft 116 may be supported at one end by the tip 112 of the distal shaft 108.

[0036] The main shaft 106 has an inner cavity for receiving the first concentric shaft 118 and the second concentric shaft 120. The distal shaft 108 has an inner cavity for the main shaft 106 to be slidably inserted into the distal shaft 108. The main shaft 106 is locked at a variable position along the distal shaft 108 to provide a desired length of the trekking pole 100. In some examples, the end portions of the main shaft 106 and the distal shaft 108 are slidably disposed in the secondary shaft 116. In some examples, when in the trekking pole configuration 102, one or more end portions of the main shaft 106 or the distal shaft 108 extend from the secondary shaft 116.

[0037] In some examples, the trekking pole 100 includes a locking member 122 to secure the main shaft 106 at a variable position on the distal shaft 108. Thus, the locking member 122 can provide the trekking pole 100 with a variable length.

[0038] To convert the trekking pole 100 to the tripod configuration 104, the locking member 122 is unlocked to allow the distal shaft 108 to slide on the main shaft 106. The distal shaft 108 can slide on the main shaft 106 to adjust the length of the trekking pole 100. The handle device 110 is removed from the housing 124 at the top of the main shaft 106. The concentric shafts 118, 120 are removed from the inner cavity of the main shaft 106 through the housing 124. As shown, the first concentric shaft 118 and the second concentric shaft 120 are then attached to the housing 124 coupled to the main shaft 106. The housing 124 includes an engagement structure 126 for attaching the concentric shafts 118, 120 in the tripod configuration 104. The engagement structure 126 may include threaded holes or other structures to receive the concentric shafts 118, 120. In some examples, the housing 124 includes a T-slot or other structure to receive the adapter 109. It should be noted that the handle assembly 110 can be reattached to the housing 124 when the trekking pole 100 is in the tripod configuration 104. In other words, the handle assembly 110 can be reattached to the housing 124 after the concentric shafts 118, 120 are removed from the housing 124.

[0039] It should be noted that after the main shaft 106 is removed from the distal shaft 108, the secondary shaft 116 can then be separated from the distal shaft 108. In some examples, the locking member 122 can be used to receive the secondary shaft 116 on the distal shaft 116 for applications other than a tripod. For example, the secondary shaft 116 can be used to increase the vertical length of the trekking pole 100. The distal shaft 108 does not need to be removed from the main shaft 106 to convert the trekking pole 100 to the tripod configuration 104.

[0040] Stability is achieved in the tripod configuration 104, wherein the main shaft 106, the distal shaft 108, and the concentric shafts 118, 120 are arranged in a tripod posture. In one example, a hiker can thus use the trekking pole 100 as a support during hiking and as a tripod for mounting various devices (e.g., cameras, observation equipment, etc.).

[0041] Figure 2 1 is an exploded view illustrating various components that may be used to form an example improved trekking pole 100 as described herein. The components include a plunger 128, a D-ring connector 130, a handle assembly 110, a housing 124 having an engagement structure 126, a grip 114, a main shaft 106, a locking member 122, a distal shaft 108, a secondary shaft 116, first concentric shafts 118a-118b (e.g., forming a first tripod leg), and second concentric shafts 120a-120b (e.g., forming a second tripod leg).

[0042] In some examples, each concentric shaft rod 118a-118b, 120a-120b can be formed by two or more nested shaft rods. For example, the first concentric shaft rod 118a-118b includes the first shaft rod 118a that slides in the second shaft rod 118b. The twistable friction mechanism 187 can lock the first shaft rod 118a and the second shaft rod 118b in place. Therefore, the first concentric shaft rod 118a-118b can be extended to a desired length. Similarly, the second concentric shaft rod 120a-120b includes the first shaft rod 120a that slides in the second shaft rod 120b. The twistable friction mechanism 187 can lock the first shaft rod 120a and the second shaft rod 120b in place, thereby providing an adjustable length for the second concentric shaft rod 120a-120b. It should be noted that in other embodiments, the concentric shaft rods can each include a single shaft rod. In other embodiments, the concentric shaft rods can each include more than two shaft rods.

[0043] Figure 3 An exploded view of the first concentric shaft 118 and the second concentric shaft 120 of the improved trekking pole 100 is illustrated according to one example of the principles described herein. Figure 3 In the embodiment, the main shaft 106, the secondary shaft 116 and the distal shaft 108 are assembled. In one example, the first concentric shaft 118 has an inner cavity for receiving the second concentric shaft 120. The inner cavity of the first concentric shaft 118 can extend partially or completely through the inner body of the first concentric shaft 118. This fit can be a friction fit or a sliding fit. The inner cavity of the first concentric shaft 118 has at least a depth to achieve a substantial length or a full length of the second concentric shaft 120 to fit therein. In the case of more than two concentric shafts, the telescopic configuration is continued, wherein the subsequent concentric shaft is received inside the previous concentric shaft. As shown in FIG. Figure 2 As described above, the concentric shafts 118, 120 may each include one or more shafts.

[0044] In the trekking pole configuration 102, the main shaft 106 includes first and second concentric shafts 118, 120 within a lumen of the main shaft 106. The lumen of the main shaft 106 may extend partially or completely through the inner body of the main shaft 106. The lumen of the main shaft 106 has at least a depth that enables a substantial length or a full length of the first and second concentric shafts 118, 120 to fit therein.

[0045] Outboard of the main shaft 106 is the distal shaft 108. The main shaft 106 is slidably inserted to a variable extent within the distal shaft 108. The distal shaft 108 is a shaft that includes a tip 112 at the end of the trekking pole 100 that contacts the ground. The distal shaft 108 is attached to the main shaft 106 at variable positions along the length of the distal shaft 108. The distal shaft 108 may have a friction fit, a screw fit, or other fit to maintain the distal shaft 108 coupled within the main shaft 106.

[0046] The distal shaft 108 is slidably inserted within the secondary shaft 116. In other words, the distal shaft 108 is inserted within the opposite end of the secondary shaft 116 relative to the primary shaft 106. It should be noted that in some examples, the outer diameter of the end of the tip 112 at the end of the distal shaft 108 is large enough to provide a circumferential lip for the circumferential edge at the first end of the secondary shaft 116 supported. In other words, the diameter of the end of the tip 112 can be larger than the inner diameter of the secondary shaft 116 so that the tip 112 retains the first end of the secondary shaft to the trekking pole in the first configuration (i.e., the trekking pole configuration 102). When used in the trekking pole configuration 102, the secondary shaft 116 is retained (stored) in position on the distal shaft 108. Therefore, the secondary shaft 116 is a shaft that can be concentrically retained on the distal shaft 108 and the primary shaft 106. The secondary shaft 116 may be deployed (ie, removed from the distal shaft 108 and the primary shaft 106) as a support for a shelter (eg, a tent) or as a vertical riser for mounting a camera, spotting scope, or other optical device.

[0047] It should be noted that in some embodiments, the trekking pole 100 may not use the secondary shaft 116. For example, in some embodiments, the trekking pole 100 may not have the secondary shaft 116 attached to the outside of the distal shaft 108. In other embodiments, the secondary shaft 116 may be used for various attachments. For example, the secondary shaft 116 may be used to achieve additional height and for various other applications.

[0048] In one example, the length of the distal shaft 108 is longer than the secondary shaft 116 so that it protrudes from one or both sides of the secondary shaft 116. The outer diameter of the distal shaft 108 is larger than the main shaft 106 so that the main shaft 106 can be slidably fitted within the hollow portion of the distal shaft 108. The locking member 122 can be used to attach the distal shaft 108 to the main shaft 106, wherein the main shaft 106 is positioned at a variable position along the length of the distal shaft 108.

[0049] In another example, the distal shaft 108 and the main shaft 106 are attached to the secondary shaft 116. The attachment of the distal shaft 108 and the main shaft 106 can be at a variable position or a fixed position. For example, the secondary shaft 116 can include locking members (e.g., adjustable clamps at either end), each locking member releasably coupling the distal shaft 108 and the main shaft 106 to the secondary shaft 116.

[0050] Figure 4A An exploded view of the extension components, namely the secondary shaft 116, the distal shaft 108, the main shaft 106 and the locking member 122 of the trekking pole 100 is illustrated. In this example, the locking member 122 is a clamp that can be loosened and tightened around the periphery of the main shaft 106 and the distal shaft 108. It should be noted that for clarity, the handle device ( Figure 1 , 110) not shown Figure 4A middle. Figure 5 An example of a handle device 110 shown in an exploded view is provided in FIG.

[0051] Figure 4B An assembly view of the extension component of the trekking pole 100 is illustrated. In this view, the trekking pole 100 is not extended. The distal shaft 108 is slidably fitted in the secondary shaft 116, wherein the distal tip 112 of the distal shaft 108 extends. The secondary shaft 116 also slides on the main shaft 108 coupled to the distal shaft 108. The main shaft 106 is completely or substantially received in the secondary shaft 116. When the locking member 122 is in a desired position around the main shaft 106 and the distal shaft 108, fixation can be performed.

[0052] Figure 4C An assembly diagram of the elongated component of the convertible trekking pole 100 in the extended configuration is illustrated. The main shaft 106 is positioned with the main portion extending out of the secondary shaft 116. The secondary shaft 116 is sleeved over the main shaft 106 and / or the distal shaft 108 and provides retention of the distal end 112 and the locking member 112. The distal shaft 108 is substantially disposed within the secondary shaft 116. When the locking member 122 is in a desired position around the main shaft 106 and the distal shaft 108, it can be secured.

[0053] Figure 4D The example locking member 122 is illustrated in an open position, while Figure 4E An example locking member 122 is illustrated in a closed position. As described above, the locking member 122 attaches the main shaft 106 to the distal shaft 108. The locking member 122 includes a locking arm 138 and a circumferential ring 140. The locking arm 138 pivots outward to loosen the circumferential ring 140 and pivots inward to tighten the circumferential ring 140. The locking member 112 may be adjustable for circumferential compression.

[0054] Figure 4E A cross-sectional view of an example locking member 122 in an open position is illustrated. The locking member 122 may also include an inner circumferential lip 142 at the second end of the locking member 122. The inner circumferential lip 142 may be seated against the outer surface of the main shaft 106 to prevent the locking member 122 from sliding down the main shaft 106 when the clamp is loosened or jostled. In addition, the distal shaft 108 may be inserted into the opening at the first end of the locking member 122, and the inner circumferential lip 142 may be sized to prevent the distal shaft 108 from extending beyond the second end of the locking member 122.

[0055] like Figure 4E As shown, the secondary shaft 116 can be slid on the distal shaft 108 until the first end of the secondary shaft 116 contacts the edge 144 on the distal tip 112 of the distal shaft 108. With respect to assembly, the locking mechanism 122 can be positioned on the distal shaft 108 and then slid onto the primary shaft 106. The locking mechanism 122 can then be slid on the distal shaft 108 to contact the second end of the secondary shaft 116. Thus, the distal tip 112 of the distal shaft 108 can hold the first end of the secondary shaft 116, and the locking member 122 can hold the second end of the secondary shaft 116 to limit axial and rotational movement of the secondary shaft 116 along the distal shaft 108. As shown, the outer circumference of the secondary shaft 116 is aligned with the outer circumference of the annular shoulder at the end 144 of the distal tip 112 of the distal shaft 108.

[0056] The locking member 122 may be any member that allows the main shaft 106 to be locked to more than one position along the length of the distal shaft 108. In addition to clamps, examples of the locking member 122 include cam locks, snap locks, friction fits, screw fits, twist locks, spring locks, coupling members, and spring-loaded components. In addition, the locking member 122 may be integral with the main shaft 106 or the housing 124 so that it is not a removable component.

[0057] Figure 5 The handle assembly 110, the plunger 128 and the spindle rod 106 are illustrated. Figure 5 In the view of FIG. 1 , the first and second concentric shafts 118, 120 are shown slightly protruding from the spindle 106 and the housing 124 to provide a perspective view of the assembly. In some examples, the handle assembly 110 is hollow and the housing 124 above the spindle 106 is hollow. In other examples, the handle assembly 110 may not be hollow.

[0058] In some examples, the handle device 110 includes a handle adapter 146. This can be a part that fits into the cavity of the housing 124. The handle adapter 146 can interface with other types of functional handles for various applications. In some examples, the handle adapter 146 can be longer or shorter based on the application. The handle adapter 146 can also provide a tubular member to be received in the handle. In some examples, the handle device 110 can also have a tip that can be constructed for specific applications such as an ice head or a digging device.

[0059] The handle adapter 146 of the handle device 110 fits within the cavity of the housing 124 and is locked to a locking hole 148 in the housing 124 by a locking structure (such as a D-ring connector 130, as shown). In one example, the D-ring connector 130 can be threaded and received through the locking hole 148 of the housing 124 and threaded to a corresponding threaded hole 150 on the end 146 of the handle device 110. As shown, the locking hole 148 is located on one side of the housing 124. In one example, the top of the handle device 110 is threaded to allow items to be attached to the top of the handle 110. It should be noted that in other embodiments, a pin or other non-threaded fastener can be used to attach the handle device 110 to the housing 124.

[0060] The plunger 128 is an elongated member having impact resistance or other properties that provide compression. For example, the plunger 128 may be formed of an elastically deformable material. During use, a small object may be placed in the hollow portion of the handle device 110, and then the plunger 128 may be inserted into the handle to achieve a fit that maintains the small object so that the small object does not move within the handle device 110. The object is thus cushioned and may be slightly compressed within the handle device 110. Thus, the object is prevented from being jostled within the handle device 110. Other properties of the plunger 128 may include being spring-like or otherwise able to recover its original shape after compression.

[0061] In one example, the plunger 128 can be lengthened or shortened. In one example, the plunger 128 can be made of foam or other material that can be cut to shorten. In another example, the plunger 128 can be made of multiple pieces, each of which is removably attached so that the plunger 128 can be lengthened or shortened, or otherwise changed in length as needed. This allows objects of various sizes to be arranged and accommodated in the handle as needed.

[0062] In some embodiments, a plurality of different handle devices 110 may be interchangeably attached to the housing 124. In this case, the housing 124 is configured to receive different handle devices 110, each having a different purpose. In some embodiments, one handle device 110 is tipped to hold an object (e.g., a camera, an optical table, a rifle mount, etc.), and a different handle device 110 includes a mechanism for obtaining a fulcrum (purchase) on steep terrain (e.g., an ice axe). Different handle devices 110 may be interchangeably attached to the housing 124 based on a given use case.

[0063] Steering Fig. 6A , showing the receiving holes 152, 154 of the engagement structure 126 of the housing 124, the receiving holes 152, 154 will receive the first and second concentric shaft rods 118, 120 respectively. The first receiving hole 152 can receive the first concentric shaft rod 118, and the second receiving hole 154 can receive the second concentric shaft rod 120. The receiving holes 152, 154 are threaded to provide a secure fit and proper angle of the first and second concentric shaft rods 118, 120 with the housing 124 (which is also threaded).

[0064] The housing 124 may be a separate unit attached to the spindle 106, or may be part of the spindle 106. Fig. 6A As shown, the housing 124 is attached to the spindle 106. For example, the housing 124 includes a hollow sleeve 156 adjacent to the engagement structure 126. The hollow sleeve 156 receives the spindle 106. The remainder of the spindle 106 may have a smaller diameter than the hollow sleeve 156 to achieve a sleeker device.

[0065] In some examples, the housing 124 includes a tie down hole 158. The tie down hole 158 may be located below the receiving holes 152, 154 and is used to insert a tether or rope to tie the trekking pole 100 when it is in the tripod configuration. Fig. 6A Also shown in the figure is a grip portion 114 below the housing 126, which includes a material that facilitates the user to grasp the trekking pole 100 when the walking terrain changes, so as to make instant adjustments to achieve comfort and safety during walking.

[0066] Figure 6BThe locking configuration of the concentric shafts 118, 120 in a tripod configuration according to one example of the principles described herein is illustrated. In particular, the first and second concentric shafts 118, 120 are attached (e.g., screwed) to the housing 124. In some examples, the receiving holes 152, 154 are angled outwardly and downwardly relative to the central axis of the main shaft 106. Therefore, the first and second concentric shafts 118, 120 can be angled outwardly and downwardly relative to the main shaft 106 to form a stable tripod configuration. In some examples, the shafts 118 and 120 can be attached to the housing 124 by a connecting mechanism. Some examples of connecting mechanisms include threaded fasteners, twist-lock compression locks, compression fits, slide fits, or other structures that realize assembly and disassembly (disassembly) of the shafts 118 and 120 and the housing 124. In one example, the ends of the shafts 118, 120 include threads to thread into corresponding threads in the receiving holes 152, 154 of the housing 124. In another example, the holes 152, 154 can provide a compression fit to capture the ends of the shafts 118, 120.

[0067] Figure 7 A distal shaft 108 is illustrated having a distal tip 112 at the distal end of the distal shaft 108. In some examples, the distal tip 112 is a metal material, although other materials (e.g., plastic, elastomer, wood, etc.) may also be used for the distal tip 112. The distal shaft 108 is attached to or formed with the distal tip 112. The distal tip 112 includes a distal end 144, the outer periphery of which forms an annular shoulder that supports the bottom circumference (not shown) of the secondary shaft 116, which may be slid onto the distal shaft 108.

[0068] In some examples, tip 112 is used to attach other functional accessories and may be threaded, slotted, or friction fit. Such accessories may include a fish gaff spear, a fishing rod guide, an oaring paddle, or a stand platform (not shown).

[0069] Various components can be attached to the tip 112 of the distal shaft 108. For example, the illustrated example distal sleeve 134 and snow basket 136 can be attached. The various components provide support for various terrains and conditions. The distal sleeve 134 provides a stable entrenchment to the ground, with a sharper tip for rocky terrain, and the snow basket 136 provides a larger footing area on the ground for ice and snow terrain. In one example, the distal shaft 108 is also removably attached to the main shaft 106, so that various embodiments of the distal shaft 108 can be attached.

[0070] In some embodiments, the tip 112 may also include threads 193 to support a stable locking mechanism for attachment to the tip 112. For example, a paddle tip may be securely screwed to the threads 193 of the tip 112 to convert the trekking pole 100 into a paddle. In another example, a fishing rod guide may be screwed onto the threads 193 to convert the trekking pole 100 into a fishing rod. In yet another example, a spear head may be attached to the threads 193 of the tip 112. Thus, the tip 112 may be an interface for attaching additional attachments to the trekking pole 100. It should be noted that different types of securing methods may be included on the tip 112 to secure the attachment. For example, the tip 112 may include a threaded friction mechanism, a groove spring lock, a twist lock, etc. Thus, the tip 112 provides a connection interface (e.g., threads 193) for different attachments that may be removed from the tip shaft 108. The tip 112 may also include grooves (not shown) or other structures to secure the attachment to the tip 112.

[0071] Fig. 8A T-slot 164 is illustrated on trekking pole 100 according to one example of principles described herein. Figure 8B A close-up view of a T-slot 164 is provided. The T-slot 164 is located on the housing 124 that is attached to the spindle rod 106. The T-slot 164 can be coupled to an adapter 109 that will be slidably inserted into the housing 124 and held in place. The adapter 109 can support components such as a camera, a viewing mirror, or other objects.

[0072] In one example, a T-slot 164 is formed on the housing 124. Specifically, as shown, the T-slot 164 is formed on the housing 124 on a surface opposite to the receiving holes 152, 154 that receive the concentric shaft rods 118, 120. The T-slot 164 prevents the adapter 109 from sliding and rotating along the main shaft rod 106. Various items can be connected to the adapter 109 attached to the T-slot 164. Fig. 8AThe adapter 109 shown in FIG. 1 includes a support for a camera, camping light, tent tie-down point, or other device. The adapter 109 may have a component that is adjustable and movable relative to the T-slot 164, which anchors the bottom of the adapter 109 in place relative to the main shaft rod 106. This allows the tripod configuration to be maintained in a fixed position when the adapter 109 is adjusted. This also makes the adapter 109 stable in the environment, even if there is wind, rain, or jostling movement that would otherwise cause the adapter 109 to fall off the main shaft rod 106.

[0073] The location of the T-slot 164 can be anywhere along the spindle 106 or the housing 124. In some examples, the accessory 109 can slide through the T-slot 164 and bottom out, as shown. In other examples, the T-slot 164 can be threaded or attached to the housing 124 via other mechanisms. As shown, the T-slot 164 is positioned on opposite sides of the receiving holes 152, 154, however, other locations are foreseen.

[0074] Fig. 9 Adapter 109 is illustrated as being attached to T-slot 164 on convertible trekking pole 100 according to one example of principles described herein. As described above, adapter 109 may be used to hold a camera, mounting platform, or other external component.

[0075] exist Fig. 9 Also visible is the cavity 168 of the housing 124 of the main shaft 106, which is exposed when the handle arrangement 110 is removed from the top of the housing 124. The concentric shaft 120 can be inserted into the cavity 168 when the trekking pole 100 is in the trekking pole configuration.

[0076] In one example, an external component (not shown) may be attached to the housing 124 via the cavity 168. For example, the external component may include a tip that is inserted into the cavity 168 of the housing 124. The exposed portion of the external component may include a structure for holding an object (not shown). The object may include an item such as a camera or other device or object that is attached to the spindle shaft 106. In another example, the object itself is directly attached to the cavity 168 of the housing 124. An example of an external component is a mounting platform ( Figure 2 , 132).

[0077] Fig.10The distal shaft 108, the secondary shaft 116, the mounting platform 170 and the retainer 172 are illustrated. As previously described, during use, the secondary shaft 116 can be slid on the distal shaft 108 (the distal shaft 108 is inserted into the secondary shaft 116). The secondary shaft 116 is removed (taken out, removed) when the tripod configuration is formed. In addition, when the handle device 110 is removed from the cavity 168 of the housing 124 of the main shaft 106, the retainer 172 can be inserted into the cavity 168 of the housing 124. Like the handle device 110, the retainer 172 includes an insert portion on one side, which is inserted into the cavity 168 of the housing 124. On the opposite side, the retainer 172 includes a ring 172, through which the secondary shaft 116 can be inserted and fixed. The secondary shaft 116 can be, for example, held in a vertical position, such as Fig.11 Thus, the secondary shaft 116 provides additional height at which various structures and fixtures may be coupled to the tripod. Fig.10 Also depicted is a mounting platform 176, which may include a platform and a ring 176 that can be attached to the secondary shaft 116 at variable positions. As shown, the mounting platform 132 is attached at the top of the secondary shaft 116. In one example, the mounting platform 132 includes a ledge to support the device. In one example, the mounting platform 132 is adjustable so that it can be angled relative to the ring.

[0078] Also in Fig.10 , note that the distal shaft 108 includes an inverted T-slot 178 at its top. This allows the top side portions of the distal shaft 108 to be squeezed together - at which point the locking member 122 is arranged on the overlapping portions of the distal shaft 108 and the main shaft 106 to secure them together in a variable position.

[0079] Fig.11 An example is provided in which a holder 172 is inserted into the interior of the housing 124. The secondary shaft 116 is secured to the ring 174 of the holder. The mounting platform 170 is attached at the top of the secondary shaft 116. In this way, the mounting platform 170 is raised to a height above the tripod.

[0080] Figures 12A-12E A view of a housing 124 for a trekking pole 100 according to one example is illustrated. As described herein, the housing 124 includes an engagement structure 152 with threaded receiving holes 152, 154. The first receiving hole 152 receives the threaded end of the first concentric shaft 118. The second receiving hole 154 receives the threaded end of the second concentric shaft 120. In some examples, there is no specific receiving hole for a specific shaft. In other words, the shafts 118, 120 can be interchangeably inserted into any receiving hole 152, 154.

[0081] In some examples, the housing 124 includes a tie hole 158. The tie hole 158 can be located below the receiving holes 152, 154. The tie hole 158 can be used to insert a tether or rope to tie the trekking pole 100 when it is in the tripod configuration.

[0082] The housing 124 includes a receiving structure 188 to receive a corresponding insertion structure. For example, the handle device 110 (not shown) may include an insertion structure that is inserted into the receiving structure 188. The receiving structure 188 may include a key hole 148 to receive a connector (e.g., a D-ring connector 130). In some examples, the housing 124 may be threaded to retain the D-ring connector 130, thereby preventing the D-ring connector 130 from being lost, while still allowing the handle device 110 to be easily removed. In some examples, the handle device 110 may be grooved and may include an O-ring to improve the fit between the handle device 110 and the receiving structure 188.

[0083] The receiving structure 188 can form a cavity 168 to receive an insertion structure (e.g., Fig.13 , 180). A hole 190 can be formed through the entire housing 124 to allow the concentric shafts 118, 120 to pass through the housing 124. In some examples, the housing includes a lip 192 located on the bottom surface of the cavity 168. The lip 192 can engage the threaded head of the first concentric shaft 118 to prevent the first concentric shaft 118 from passing through the hole 190.

[0084] The housing 124 includes a hollow sleeve 156 to receive and couple to the spindle 106 (not shown). For example, the spindle 106 can be inserted into the hollow sleeve 156 and attached (eg, glued, welded, screwed, etc.) to the hollow sleeve 156.

[0085] The housing 124 also includes a T-slot 164 to facilitate coupling with the adapter. The T-slot 164 can be positioned on the housing 124 so that the adapter faces upward when the trekking pole 100 is in the tripod configuration.

[0086] Figures 12D-12EThe housing 124 is illustrated, which has a D-ring stop 183 to retain the D-ring connector 130 when the accessory (e.g., the handle device 110) is removed from the cavity 168 of the housing 124. The D-ring stop 183 can extend from the outer wall of the receiving structure 188. The D-ring stop 183 can include threads that intersect with threads on the D-ring connector 130. When the accessory (e.g., the handle device 110) is connected to the housing 124, the threads of the D-ring connector 130 can engage the threads of the accessory. When the D-ring connector 130 is withdrawn from the accessory, the threads of the D-ring connector 130 can engage the threads of the D-ring stop 183. The accessory can be removed from the housing 124 while the D-ring connector 130 is left engaged with the D-ring stop 183, thereby avoiding the loss of the D-ring connector 130. In some examples, the housing 124 includes two or more D-ring stops 183, which are located on different sides of the receiving structure 188.

[0087] Fig.13 A holder 172 for a trekking pole 100 according to an example of the principles described herein is illustrated. The holder 172 includes an insertion structure 108. In some examples, the insertion structure 180 can be configured to be inserted into a receiving structure (FIGs. 12a-12c, 188) of the housing 124. The insertion structure 180 includes a hole 182 to receive a connector. For example, the hole 182 can be threaded to receive a threaded D-ring connector 130, or can be unthreaded to receive a pin. In some examples, the holder 172 can include multiple holes to allow a connector to pass through the insertion structure 180.

[0088] The holder 172 includes a ring 174 to receive the secondary shaft 116 (not shown). For example, when the trekking pole 100 is in a tripod configuration, the secondary shaft 116 can be inserted into the ring 174 to form a vertical support structure. This can be as shown in FIG. Fig.11 to be completed as shown.

[0089] The retainer 172 can include a body 181 coupled to the insert structure 180. In some examples, the body 181 can be attached to the insert structure 180 at an angle, thereby allowing the ring 174 to support the secondary shaft 116 in a substantially vertical orientation.

[0090] Fig.14 1 shows a mounting platform 170 attached to a secondary shaft 116 according to one example of the principles described herein. The mounting platform 170 includes a ring 176 to receive the secondary shaft 116. For example, when the trekking pole 100 is in a tripod configuration, the secondary shaft 116 can be inserted into the ring 176. This can be as shown in FIG. Fig.11 to be completed as shown.

[0091] The mounting platform 170 includes a mounting surface 184 coupled to the ring 176. The mounting surface 184 provides a surface to attach an object (eg, a camera). The mounting surface 184 includes a slot 186 to receive a fastener for mounting an object to the mounting surface 184.

[0092] A further example of the trekking pole 100 includes a plurality of secondary shafts that are in a concentric form so that they can fit on the distal shaft 108 in the trekking pole (i.e., first) configuration. For example, the plurality of secondary shafts can be nested within each other and slid on the distal shaft 108 to be accommodated during travel. Once removed, the plurality of concentric secondary shafts can be used in various structures, including, for example, scaffolding for tents, holder structures for artist easels, relatively high vertical platforms for optical devices, various camera facilities, and other structures including tripod facilities or connection facilities. In some examples, the plurality of secondary shafts can be used as a scaffolding for a hunting blind or any shelter - utilizing a pyramid formation formed by the concentric shafts 118, 120 or any kind of alternative structure of the concentric shafts 118, 120, the distal shaft 116, the main shaft 106 and / or any secondary shaft 116.

[0093] Figures 15A-15B 1 illustrates a mounting platform 132 according to one example. In some examples, when the trekking pole 100 is in a tripod configuration, the mounting platform 132 can be used to support accessories (e.g., a camera) instead of using the secondary shaft 116, such as Fig.13 and Fig.14 For example, Figures 15A-15B The mounting platform 132 may allow a user to use the trekking pole 100 as a tripod from a sitting or squatting position. The mounting platform 132 may be inserted into the cavity 168 of the housing 124 to provide a platform for optical devices, rifle mounts, etc. The mounting platform 132 may include a hole 195 to receive a connector (e.g., a D-ring connector 130). The connector may secure the mounting platform 132 to the housing 124. The mounting platform 132 may include a slot 196 to allow a fastener to connect an accessory to the mounting platform 132.

[0094] Fig.16 A trekking pole 100 is illustrated with a mounting platform 132 that supports a camera according to one example. In this case, the mounting platform 132 is mounted within a housing 124. Concentric shafts 118, 120 are attached to the housing 124 to form a tripod with the main shaft 106. An adapter 109 is connected to the mounting platform 132 to support the camera.

[0095] Figures 17A-17BAnother embodiment of a mounting platform 189 according to one example is illustrated. In this example, the trekking pole 100 can be used to support accessories (e.g., rifle mounts, optical devices, cameras, etc.) in a monopod position. For example, when in the trekking pole configuration, the mounting platform 189 can be inserted into the cavity 168 of the housing 124. The mounting platform 189 includes an insert structure 191, which is to be inserted into the cavity 168 of the housing 124. A groove 193 can be formed on the insert structure 191 to receive an elastomeric O-ring 194, which provides a tight connection between the mounting platform 189 and the cavity 168 of the housing 124. In this example, the mounting platform 189 includes a plurality of threaded holes 197, 198 to receive fasteners of different sizes. For example, the first threaded hole 197 can be a 1 / 4"-20 threaded hole, and the second threaded hole 198 can be a 3 / 8"-16 threaded hole. It should be noted that a single threaded hole can be used. In addition, the threaded hole can also have a size different from that described. In yet another example, fasteners (not shown) can be mounted to the mounting platform 189 to connect with accessories.

[0096] Fig.18 The mounting platforms 189 and different accessories 109 for the trekking pole 100 are illustrated. In a first example, the mounting platform 189a is connected to the rifle mount 109a. The mounting platform 189a can be inserted into the cavity 168 of the housing 124. In a second example, the mounting platform 189b is connected to the optical scope adapter 109b. The mounting platform 189b can be inserted into the cavity 168 of the housing 124.

[0097] Fig.19 A trekking pole 100 in a monopod configuration is illustrated. Fig.19 In the embodiment of the present invention, a hiker, hunter, or anyone using the trekking pole 100 in the trekking pole configuration 102 can remove the handle 110 and fit another attachment (e.g., the angled mounting platform 132 or the flat mounting platform 189) into the cavity 168 of the housing 124. Fig.19 1, the angled mounting platform 132 is shown inserted into the housing 124. However, different mounting platform embodiments may be used. The adapter 109 may be attached to the mounting platform 132. For example, such an adapter 109 may support any functional equipment including, but not limited to, a platform for optical devices, a hunting rifle rest, a camera, binoculars, or any other optical device. When in this configuration, the user may utilize the grip 114 to hold the trekking pole 100 during use.

[0098] The shafts, shaft variations, extension members, and other components described herein may be made of aluminum, carbon fiber, steel, plastic, wood, combinations thereof, or other materials. The devices described herein contribute to the hiking, backpacking, hunting, and tripod fields for several reasons including, but not limited to, providing a lightweight, simple, stable, strong, and compact, convertible, multi-purpose, convertible pole.

[0099] The shafts are detachable, concentric, telescopic or otherwise variable to achieve a compact size, which allows the overall length of the pole to fit conveniently within luggage or under a seat or other location where a traveler wants to stow the device. It is envisioned that the shafts of the tripod and bipod assemblies are completely released from each other to achieve a compact arrangement for transport or storage.

[0100] In some examples, the trekking pole 100 may include shock absorbers, which include springs or elastic materials that cushion the impact of the trekking pole when it hits the ground. In addition, the trekking pole 100 may also include a basket (e.g., Figure 7 , 136), which is similar to the disc or cone on a ski pole. The basket prevents the tip of the pole from digging too deep into the ground or snow and getting wedged between tree roots and rocks.

[0101] The description of various embodiments of the present invention is shown for illustrative purposes and is not intended to be exhaustive or limited to the disclosed embodiments. Various modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the embodiments. The terms used herein are selected to best illustrate the principles of the embodiments, practical applications, or technical improvements relative to the prior art in the market, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein.
