Description

[0001] Priority details

[0002] This application claims priority to AU 2021901841, filed in Australia on 18 June 2021, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This invention generally relates to the field of mechanical fastening devices. Background Technology

[0004] Mounting channels are well-known mounting systems: a channel nut within the mounting channel allows items to be bolted to it, and the channel allows the item's position to be changed by sliding along the channel nut. However, the channel nut must be wider than the flange of the mounting channel to ensure that it can be pushed against the flange and held in place. Therefore, prior art systems require a device for inserting the channel nut into the channel.

[0005] Some existing systems (such as those disclosed in AU 2011286169) utilize widened holes spaced along the channel, which allow slotted nuts to be inserted into the channel. However, this requires specialized machinery to cut or otherwise shape the holes into the channel structure. This is problematic when the channel is part of an extrusion structure; typical extrusion processes do not readily allow the structure of the extruded product to vary along its length, thus requiring additional manufacturing steps (and associated increased costs) to cut or shape the holes. Another disadvantage of this perforation method is that the channel fastening hardware must slide along the channel from the nearest hole into its desired position on the rack. If an existing item already secured to the channel exists in this path, it needs to be removed and subsequently reassembled while the item is being assembled. This can be a time-consuming process, especially if it needs to be performed periodically and / or in the field.

[0006] Other systems provide an open end to the passage, requiring a slotted nut to be fed along the length of the passage to the desired position. This necessitates either a permanently open end to the passage, or, if the passage is integrated into the body of the structure, a structure that can be opened or at least partially disassembled to access the passage. This presents several problems, as permanently open passage ends and openable hatches provide a breeding ground for dirt, dust, and other contaminants and can attract spiders and insects, especially when existing systems are used in off-road and / or rural or wild environments. On the other hand, routine disassembly can weaken the connections between components over time.

[0007] Certain channel fasteners are adapted to be inserted into typical channels and typically comprise a slotted nut having a "long" axis and a "short" axis. The slotted nut is inserted into a channel with its "long" axis aligned with the channel direction. Once inserted, the slotted nut can be rotated within the channel such that the "long" axis of the slotted nut is transverse to the channel, thereby allowing the slotted nut to contact the channel flange. However, this prior art slotted nut has several drawbacks. As those skilled in the art will understand, the slotted nut can often be implemented "invisibly" because accessories or other items can rest on the channel for installation, or the channel may be outside the user's direct line of sight, thus obscuring the slotted nut from the user during tightening and screwing. With this in mind, and referring to Figure 1A, which illustrates a prior art slotted nut P-10 (disclosed in US 4,784,552), many prior art rotatable slotted nuts rely on fasteners P-12 (such as threaded bolts) to drive rotation. Insufficient friction between the slotted nut P-10 and the fastener P-12, the slotted nut getting stuck in something within the channel P-14, or other such obstructions can prevent the prior art slotted nut P-10 from rotating properly. This "invisible" implementation of the slotted nut P-10 may prevent the user from recognizing whether the slotted nut is under-rotated or over-rotated, resulting in potentially improper fastening.

[0008] Many prior art fasteners (such as slotted nuts P-10) can also rely on channels P-14 having inwardly curved flanges P-16. While the risk of over-rotation can be mitigated by engaging with protrusions on the slotted nut P-10, damage to the flange P-16, or the absence of channels formed by the curved flange P-16 (e.g., flanges that are straight and parallel to each other), will potentially, and not properly, receive the prior art slotted nut P-10.

[0009] Furthermore, referring to Figure 1B, another prior art fastening device P-20, including a channel bolt and an associated nut as disclosed in AU 2020101180, is shown. Although the prior art fastening device P-20 can be inserted into the channel and rotated by the fastener before tightening, there may be no structural elements or other devices to ensure that the fastening device P-20 remains in the correct configuration during the tightening process. Therefore, prior art rotatable fastening devices similar to the fastening device P-20 are prone to either under-rotation or over-rotation, resulting in a risk of loss of contact between the slotted nut and the channel flange. Movement of the item or mounting surface may also cause "pushing," which could loosen the prior art fastening device P-20, which is undesirable.

[0010] During insertion and before the positioning attachment is used for installation, prior art fasteners similar to those depicted in Figures 1A and 1B also need to be rotated into the correct configuration. This can further exacerbate the risk of the fastener rotating out of position due to friction when the threaded fastener engages with it.

[0011] Figure 1C illustrates another prior art deployable fastening device, as disclosed in EP 3822495, including a slotted nut P-30. The prior art slotted nut P-30 attempts to address the risk of over- or under-rotation of the rotating portion P-32 by using a spacer element P-34, a stop element P-36, and a receiver P-38. However, since all lateral rotation of the rotating portion P-32 is directly driven by the rotation of the associated screw, the aforementioned problem is not completely resolved.

[0012] Other designs rely on spring-loaded mechanisms, increasing the complexity of the fixing device. An example of such a design is shown in Figure 1D (as disclosed in EP 0805297), illustrating a prior art slotted nut P-40 with a spring element P-42 for driving the rotation of the rotating portion P-44 relative to the mounting plate P-46. The spring element P-42 also pulls the rotating portion P-44 and the mounting plate P-46 toward each other. Furthermore, the prior art slotted nut P-40 is designed such that, for "deployment," the rotating portion P-44 must first be translated away from the mounting plate P-46 before being pulled back by the spring element P-42 to allow rotation. The spring element represents a critical failure point because if it fails, the slotted nut becomes unusable. Furthermore, particularly in the case of the existing slotted nut P-40 (which relies on spring element P-42 to pull the rotating part P-44 and the mounting plate P-46 toward each other), failure of the spring element may cause the slotted nut to "fail open" and loosen enough to detach the mounted item.

[0013] Prior art fasteners that can be inserted into a flange channel and rotated into a locking configuration without widening the opening typically also feature a top plate that rests against the outer surface of the slotted flange (see, for example, Figures 1A, 1C, and 1D) to provide leverage and / or support, allowing the slotted nut to be pulled against the inner surface of the flange. These top plates can interfere with how articles are installed into the channel, especially if the attachment points on the articles are not formed with the top plate in mind, resulting in the articles being unevenly placed against the channel. The resulting gaps can allow water, dirt, and debris to accumulate, which can lead to corrosion and other damage to the articles, the channel, or the structure forming or providing the channel.

[0014] Therefore, there is a need to provide the ability to secure an object to a point along the channel while overcoming or at least improving the shortcomings of existing technology devices. Summary of the Invention

[0015] In a first aspect, the present invention relates to a fixing device comprising an anchoring element positioned along an axis, a rotating element, and a deployment mechanism, the anchoring element extending substantially perpendicular to the axis, the rotating element being arranged perpendicular to and rotatable about the axis and spaced apart from the anchoring element along the axis, the deployment mechanism comprising a first deployment portion on the anchoring element and a second deployment portion on the rotating element, wherein one of the first and second deployment portions includes an inclined surface extending at least partially about the axis, and the other is shaped to be able to roll, slide, or otherwise move along the inclined surface, the anchoring element and the rotating element being movable toward each other along the axis, and the deployment mechanism being adapted to convert the movement of the anchoring element and the rotating element toward each other into a helical movement along and about the axis in a first hand direction.

[0016] Another aspect of the invention provides a fixing device for securing an article to a first side of a groove formed by substantially opposing flanges. The fixing device includes an anchoring element and a rotating element rotatable relative to the anchoring element, the anchoring element being configured to be located within the groove and between the opposing flanges. The rotating element is configured to be positioned on a second side of the groove and rotate about an axis substantially perpendicular to the opposing flanges. The anchoring element and the rotating element each have a width less than or equal to the width of the groove, and the rotating element has a length greater than the width of the groove. The anchoring element and the rotating element are axially movable toward each other during a tightening motion. The fixing device is convertible between an insertion configuration and a deployment configuration, in which the anchoring element and the rotating element are arranged such that their widths are aligned, and in the deployment configuration, the rotating element rotates away from the alignment with the anchoring element. The fixing device also includes a deployment mechanism configured to convert the tightening motion between the rotating element and the anchoring element into rotation of the rotating element toward the deployment configuration.

[0017] Another aspect of the invention provides a method for securing an article to a groove having a groove width and being formed by substantially opposing flanges, the groove and the flanges having a first side and a second side, the method comprising the steps of:

[0018] 1. A fixing device is provided, comprising an anchoring element, a rotating element, and a deployment mechanism, wherein the anchoring element is arranged perpendicular to an axis, and the rotating element is mechanically connected to the anchoring element and is rotatable about the axis;

[0019] 2. Insert the fixing device in the insertion configuration through the slot from the first side and at least partially insert it into the second side; and

[0020] 3. This causes the anchoring element and the rotating element to move toward each other along the axis;

[0021] Wherein, the width of the anchoring element and the rotating element is less than or equal to the width of the slot, and the length of the rotating element is greater than the width of the slot. The insertion configuration includes the anchoring element and the rotating element arranged along the axis such that the widths of the anchoring element and the rotating element are aligned, and the deployment mechanism is adapted to convert the movement of the anchoring element and the rotating element toward each other into a helical motion along and about the axis in a first-hand direction.

[0022] Another aspect of the invention provides a system for securing an attachment having opposing surfaces to a structure having a groove, the groove having an opening disposed along a longitudinal axis, the opening being at least partially defined by at least one portion of the structure extending substantially laterally toward the longitudinal axis. The system includes a fastening device having a fixing element and a restraining element, wherein the fixing element has a first diameter and a second diameter, the first diameter and the second diameter being orthogonal to each other and substantially orthogonal to a common axis, the common axis being substantially orthogonal to the longitudinal axis, the fixing element including a surface for applying stress to at least one protruding portion between the surface and the opposing surface of the attachment, and the restraining element including a first portion and a second portion, the restraining element having ... One part is capable of engaging with a groove, such that during use, the rotation of the constraint element relative to the groove and about the common axis is substantially constrained. The first conversion mechanism consists of a first part of an attachment and a first part of a fixing element, wherein, when the fastening device is received in the groove, the first attachment part engages with the first fixing element part and is rotatable about the common axis relative to the first fixing element part. The second conversion mechanism consists of a second part of a fixing element and a second part of a constraint element, wherein the second fixing element part is capable of engaging with the second constraint element part and is rotatable about the common axis relative to the second constraint element part. Both conversion mechanisms are each suitable for converting rotational motion and linear motion along the common axis. The fastening device is configured to reversibly switch between a releasable configuration and a deployment configuration. In the releasable configuration, the fastening device can be inserted into and / or withdrawn from the slot. In the deployment configuration, when the fastening device is received in the slot, the protruding portion between the surface of the fixing element and the opposing surface of the attachment is stressed. A first conversion mechanism and a second conversion mechanism cooperate to enable switching from the releasable configuration to the deployment configuration. When the fixing element and the attachment are engaged, a first variable distance extends parallel to the common axis between the surface of the fixing element and the opposing surface of the attachment, and a second variable distance extends parallel to the common axis between the surface of the fixing element and the restraining element, and between the first diameter of the fixing element and the longitudinal axis. A variable angle is formed between them. Further, the rotation of the first conversion mechanism in the first hand direction causes a first relative linear motion between the attachment and the fixing element, thereby reducing the first variable distance. The first relative linear motion in the second conversion mechanism causes a second relative linear motion, thereby reducing the second variable distance and causing the second conversion mechanism to operate. When the second conversion mechanism is operating, the reduction of the second variable distance causes the fixing element to rotate relative to the common axis in the second hand direction, thereby increasing the variable angle. This converts the fastening device from a releasable configuration to a deployed configuration and applies stress to at least one protruding portion between the fixing element surface and the opposing surface of the attachment, thereby fixing the attachment to the structure.

[0037] definition

[0038] As used herein, the term "face cam" refers to a mechanism consisting of two operable parts: a cam and a follower. The cam has a rotational axis and a surface inclined relative to that axis. The follower is configured to contact the surface such that, as the cam rotates about its axis, the follower, due to its inclined nature, is aroused by this contact to undergo a linear motion at least partially parallel to the axis. Typically, the follower is configured to undergo a linear motion parallel to the axis. The follower may be composed of a projective surface. Further description of face cams is provided in the section entitled "Transition to Deployment Configuration".

[0039] As used herein, the term "lead" refers to the movement along an axis corresponding to a single rotation about that axis for a mechanism that converts linear motion along / about an axis to manual rotational motion. It should be understood that for mechanisms that cannot undergo a single rotation, the lead is calculated based on the differential relationship between movement and rotation. Detailed Implementation

[0040] The subject matter included in the detailed specification is provided for the reader's convenience only and should not be used to limit the subject matter found throughout this disclosure or the claims. Such subject matter should not be used to interpret the claims or limit the scope of the claims.

[0041] The terminology used herein may differ in different embodiments. Therefore, the terminology introduced in the detailed specification may be used in two or more alternative forms for cross-reference. The use of alternative expressions reflects the ability to describe the same or similar features in more than one way, and is not intended to limit the features described in this way to being exclusive to any particular embodiment, nor is it intended to limit any embodiment disclosed herein to including or excluding any particular feature by using what terminology identifies any particular feature.

[0042] Those skilled in the art will further understand that, unless otherwise expressly indicated to the contrary, the embodiments of the invention disclosed herein are not exclusive to each other, and features of one embodiment may be incorporated into another. Similarly, the mere fact that a particular embodiment does not expressly describe the presence of a particular feature shall not be construed as indicating that the particular feature is absent or otherwise excluded from the particular embodiment.

[0043] In the first aspect and see also Figure 2A and Figure 2B This disclosure relates to a fixing or fastening device 10. See also one embodiment. Figure 3 The fastening device 10 can be used to secure an article or attachment 3 to a structure having a longitudinally extending slot or opening 6 and opposing flanges 8 (or at least one protrusion or flange) on either side of the slot 6. Figure 3As shown, the longitudinally extending slot 6 can lead to a channel within the interior 2 having an internal space or opposing sidewalls 4. Alternatively, the longitudinally extending slot 6 can be formed only in a structure without a channel or as part of a structure without a channel. In either alternative, the slot may not have any particular length. See also Figure 3 For example, the groove 6 may extend a certain length, and the fixing or fastening device 10 may allow the article or attachment 3 to be fixed at any point along the length of the groove.

[0044] It will be understood that the slot 6 or channel 7 need not have any particular length. Those skilled in the art will understand that, as used herein, the term slot simply refers to an opening having a longitudinally extending portion with at least one flange 8 in a suitable configuration. According to one use of the term, structure 1 may include slots 6 or channels 7 of indefinite length. According to another use of the term and see [reference needed] Figure 4 Structure 1 may include a slot 6 of a certain length. Therefore, those skilled in the art will understand that embodiments of the fastening device 10 can be used with two different forms of structure 1, and unless otherwise expressly stated, the disclosure herein should not be construed as limited to one form of structure 1.

[0045] As used herein, directional and positional terms (such as lateral / longitudinal, above / below, etc.) should not be interpreted in an absolute manner or limit the embodiments of the fixing device 10 described herein to a particular "absolute" orientation, but should be interpreted only with reference to the orientation of the fixing device within structure 1. For the sake of convention only, structure 1 may be considered to provide a reference frame in which the slot 6 is positioned "above" the interior space 2 and the opening is "upward". Those skilled in the art will understand that embodiments of the fixing device 10 can be used to rotate into structure 1 at any suitable angle without departing from the scope of this disclosure.

[0046] In an embodiment, the fixing device 10 includes a locking or restraining or anchoring element 12 and an engaging or fixing or rotating element 14, the locking or restraining or anchoring element being arranged perpendicular to axis 18 (or a common axis described below); the engaging or fixing or rotating element is mechanically connected thereto, and the rotating element 14 is also perpendicular to axis 18 and rotatable about the axis, and spaced apart from the anchoring element 12 along the axis. Embodiments of the invention also include a deployment mechanism or mechanism 16 (or a second conversion mechanism described below), the deployment mechanism or mechanism including a first portion 17 (or a first deployment portion on a first portion of the anchoring element or a restraining element described below) on the surface of the anchoring element facing the rotating element, and a second portion 19 (or a second deployment portion on a second portion of the rotating element or a fixing element described below) on the surface of the rotating element facing the anchoring element. At least one of the first part 17 and the second part 19 may include an inclined, spiral, or sloping surface or ramp 27, and the other is a compatible element 29 shaped to be able to roll, slide, or otherwise move along it (as described below, in one embodiment as a follower or reciprocal helical surface). See also Figure 2A The second part 19 of the deployment mechanism 16 is shown as including an inclined surface, but those skilled in the art will understand that this is merely an example.

[0047] In use, the anchoring element 12 and the rotating element 14 are able to move toward each other along axis 18 in a tightening motion (as described below in relation to a second relative linear motion), with the first portion 17 and the second portion 19 of the deployment mechanism 16 pushing against each other for at least a portion of the tightening motion.

[0048] In an embodiment, the fixing device 10 includes an anchoring element 12, a rotating element 14, and a deployment mechanism 16. The anchoring element is configured to be disposed within a groove 6 and between opposing flanges 8; the rotating element is configured to be positioned within the internal space 2 of the structure 1. The rotating element 14 and the anchoring element 12 are configured to be movable toward each other in a tightening movement, and the deployment mechanism 16 subsequently causes rotation of the rotating element about axis 18 (or relative rotation in a second-hand direction as described below) when the tightening movement between the rotating element 14 and the anchoring element 12 is caused. Those skilled in the art will understand that the term "tightening movement" as used herein refers only to the movement of the anchoring element 12 and the rotating element 14 toward each other, and the scope of this disclosure is not limited to which element is moving. In some embodiments, the anchoring element 12 may be movable. In some embodiments, the rotating element 14 may be movable. In some embodiments, both the anchoring element 12 and the rotating element 14 may be movable.

[0049] In some embodiments, particularly Figure 2A In the illustrated embodiment, the rotating element 14 may include a threaded hole 20 extending along axis 18 (or a first portion of a fastening element as described below), wherein a matching unthreaded hole 22 is provided in the anchoring element 12. A bolt or other threaded fastener 21 (or a first portion of an attachment as described below) may be inserted into the hole 20 to engage with the rotating element 14. In this embodiment, the rotating element 14 may function as a nut. In an alternative embodiment, the rotating element 14 may be a T-bolt, wherein the "horizontal" portion of the "T" is formed by the rotating element 14 such that a threaded fastener protrudes from the rotating element and passes through the unthreaded hole 22 in the anchoring element 12. In this embodiment, the T-bolt may engage with a suitable threaded nut.

[0050] Insertion in the slot

[0051] In the embodiments and see Figure 2A The anchoring element 12 and the rotating element 14 may each have a width W-12, W-14 (or a second diameter as described below) less than or equal to a predetermined width. The rotating element 14 may have a length L-14 (or a first diameter as described below) greater than the predetermined width. See also Figure 2A and Figure 2B In this embodiment, the fixing device 10 may have an insertion configuration 10A, wherein the anchoring element 12 and the rotating element 14 are positioned along the axis 18 such that the width W-12 of the anchoring element and the width W-14 of the rotating element are aligned (e.g., Figure 2A As shown in the diagram), and the tightening motion can cause the rotating element 14 to rotate away from the insertion configuration 10A (as shown in the diagram). Figure 2B (as shown in the image).

[0052] Unlike existing installation systems, the insertion configuration 10A (which may alternatively be referred to as the insertion configuration) provides the invention with the ability to "drop" into and deploy in any slot 6 of suitable width, without requiring the slot to include holes. Furthermore, the "insertion" capability of the invention improves upon the need for slots or channels with openings or exposed ends.

[0053] Those skilled in the art will further understand that in prior art arrangements, if two (or more) items are secured along a particular prior art slot and another item is to be secured in one of the locations therebetween, at least one of the already secured items must be completely removed so that the other item can slide into place and be secured. In contrast, the “insertion” function of this invention eliminates the need to untie, disassemble, or otherwise remove already secured items in order to secure another item to a particular slot. Those skilled in the art will understand that this presents significant advantages for users with modular or personalized item arrangements, such as those found in off-road, camping, or multi-purpose vehicles.

[0054] In an embodiment, the predetermined width may be the width of the slot 6 (or the first lateral dimension as described below). In an embodiment, the width W-12 of the anchoring element 12 and the width W-14 of the rotating element 14 are less than or equal to the width of the slot 6 (which is the predetermined width), while the rotating element has a length L-14 that is greater than the width of the slot 6.

[0055] See Figure 2A In some embodiments, the fixing device 10 includes an insertion configuration 10A (or a releasable configuration as described below), wherein the anchoring element 12 and the rotating element 14 are aligned in the width direction. Therefore, in the insertion configuration 10A, the total width of the fixing device 10 is less than or equal to the width of the slot 6. In the insertion configuration 10A, the fixing device 10 can be inserted directly through the slot 6 into the internal space 2 of the structure 1 without requiring a specially formed hole or channel opening.

[0056] See Figure 2B In some embodiments, the fixing device 10 includes a deployment configuration 10B (or a barrier configuration as described below) in which the anchoring element 12 and the rotating element 14 are aligned in the width direction and rotated away about the axis 18. In the deployment configuration 10B, the upper surface 24 of the rotating element 14 (or the surface of the fixing element as described below) is positioned below the opposing flange 8 of the channel, thereby preventing the fixing device 10 from being withdrawn from the channel.

[0057] Transition to deployment configuration

[0058] In one embodiment, the fixing device 10 may include a deployment mechanism 16 configured to cause rotation in the rotating element 14. In another embodiment, this is achieved by directly converting the tightening motion between the rotating element 14 and the anchoring element 12 into rotation of the rotating element 14 about axis 18 via the deployment mechanism 16.

[0059] To explain by way of non-limiting example, a tightening force is applied to one (or both) of the rotating element 14 and the anchoring element 12, parallel to axis 18, and moves the anchoring element 12 and the rotating element 14 toward each other. The deployment mechanism 16 converts a portion of the applied force into a rotational force, which is substantially perpendicular to axis 18 and causes rotation in the rotating element 14 about axis 18 (as will be understood below, this arrangement can be hinged according to the movement, distance of movement, and angle of movement associated with this force).

[0060] This can be seen by referring to Figures 5A-5C The non-limiting examples shown are used to explain this. Figure 5A In the middle, the anchoring element 12 and the rotating element 14 do not engage in contact. Tightening force (F) T This causes a relative tightening movement that moves only the two elements 12, 14 together and moves the deployment mechanism 16 (shown herein as extending from the rotating element 14, although those skilled in the art will understand this is merely an example) toward engagement. Those skilled in the art will understand that in embodiments utilizing the threaded fastener 21, some rotation of the rotating element 14 may be caused by the threaded fastener 21, but as previously determined, this is unreliable, and for clarity, in Figure 5A Not shown in the image.

[0061] See now Figure 5B The tightening force (F) that causes the tightening motion T The resistance (F) contacts the deployment mechanism 16 and the anchoring element 12. R This means that the resultant force (F) applied to the rotating element 14 N It has a force perpendicular to the tightening force (F) T The component of ) and therefore the resultant force (F) N It is at an angle. Finally, Figure 5C The relative movement of anchoring element 12 and rotating element 14 is shown, illustrating how at least one of elements 12, 14 rotates. Those skilled in the art will understand that the above examples are non-limiting, and that deployment mechanism 16 may be incorporated into either or both of anchoring element 12 and rotating element 14, and that different mechanisms may be used to at least partially convert tightening motion into rotational motion.

[0062] Those skilled in the art will understand that this is different from, and is in fact directly opposite to, rotation of the threaded fastener in order to induce movement of the threaded fastener (or movement in a manner similar to the first conversion mechanism described below). For example, a wrench can be used to directly rotate the nut about the threaded bolt in order to induce movement along the threaded bolt (i.e., rotational movement is converted into tightening movement). This is in contrast to this disclosure, where tightening movement (including tightening movement along the threaded fastener 21 engaging the threaded hole 20) is converted into rotational movement by deployment mechanism 16. Even in embodiments where the threaded fastener 21 engages the threaded hole 20, rotation of the threaded fastener 21 may only cause minimal direct rotation in the rotating element 14. In this embodiment, rotation of the threaded fastener 21 merely pulls the rotating element 14 and the anchoring element 12 toward each other, and it is deployment mechanism 16 that subsequently redirects the tightening movement to rotation of the rotating element 14 about axis 18, thereby transforming the fixing device 10 into deployment configuration 10B.

[0063] In this embodiment, since the rotation of the rotating element 14 about the axis 18 is not driven by friction between the rotating element 14 and the threaded fastener 21, the risk of over-rotation or under-rotation can be reduced, eliminated, or at least substantially improved.

[0064] In this embodiment, when the fixing device 10 is properly positioned within the structure 1, the anchoring element 12 can be placed within the groove 6 between the opposing flanges 8. By abutting against the flanges 8, substantial rotation of the anchoring element 12 about the axis 18 can be prevented or suppressed. This ensures that the rotating element 14 is preferentially rotated by the deployment mechanism 16.

[0065] In the embodiments and see Figure 6 And return to see Figures 5A-5C The deployment mechanism 16 may include a first portion 26 on the underside of the anchoring element 12 and a second portion 28 on the upper side of the rotating element 14. When the first portion 26 and the second portion 28 engage with each other, the tightening motion between the anchoring element 12 and the rotating element 14 is at least partially converted into rotation of the rotating element 14.

[0066] In another embodiment, either the first portion 26 or the second portion 28 is a ramp or helical surface 27, and the other is a compatible element 29 configured to slide, roll, or otherwise move relative to and along the ramp 27 (or as a follower or inverted helical surface). Without limiting the scope of this disclosure by theory, it is thought that the conversion from tightening motion to rotation can be achieved by orienting the ramp 27 such that the surface of the ramp is angled relative to the direction of the tightening motion (i.e., the ramp 27 is neither parallel nor perpendicular to axis 18). During the tightening motion between the anchoring element 12 and the rotating element 14, the compatible element 29 will form an engaging contact with the ramp 27. Further tightening motion will press the compatible element 29 into the ramp 27, causing relative movement between the compatible element 29 and the ramp 27, such that one slides, rolls, or otherwise moves along the other. This subsequently causes the rotating element 14 to rotate about axis 18.

[0067] Those skilled in the art will understand that the above theory is described in relative terms. In embodiments where the second portion 28 of the rotating element 14 is a ramp 27 (and the first portion 26 is a compatible element 29), the "compatible element" 29 will not be able to move substantially laterally because the anchoring element 12 will impact one or both of the opposing flanges 8 of the structure 1. However, the compatible element 29 and the ramp 27 move relative to each other.

[0068] In one embodiment, ramp 27 is an inclined surface of at least a partially helical cam or face cam. See also another embodiment. Figure 6 In the embodiments shown, both ramp 27 and compatible element 29 can be helical cams. In another embodiment, ramp 27 can be a female helical cam and compatible element 29 can be a male helical cam, or vice versa.

[0069] In one embodiment, the motion may be a sliding motion between two suitably shaped and / or prepared surfaces. In an alternative embodiment, the compatible element 29 or ramp 27 may include one or more bearings to allow another bearing to roll along it. Other forms of motion may exist or become apparent to those skilled in the art and are considered to fall within the scope of this disclosure.

[0070] Comparison with existing technologies for deploying channel nuts

[0071] Referring to Figure 1C of the prior art, it should be noted that the spacer element P-34 is flat and is only used to provide the necessary spacing and formation for the receiving element P-38. The rotation of the rotating part P-32 is driven entirely by friction between the rotating part and the screw element.

[0072] Referring to Figure 1D of the prior art, it should be noted that a ramp structure P-48 is disclosed. However, the function of these ramp structures P-48 is opposite to that of the deployment mechanism 16 of the embodiments of the present invention. The prior art ramp structure P-48 provides a device for converting the rotation of the rotating portion P-44 into linear motion directly away from the mounting plate P-46. The subsequent rotation, which fully engages the prior art rotating portion P-44 with the ridge of the illustrated prior art channel, is performed by the provided prior art spring element P-46.

[0073] This can be compared with embodiments of the present invention. See also Figures 5A-5C As previously discussed, the rotation of the rotating element 14 is driven by a deployment mechanism 16, which, separately from any rotation that might be caused by embodiments utilizing threaded fasteners, converts the linear motion of the rotating element 14 toward the anchoring element 12 into a substantially helical motion of the rotating element 14 about axis 18. As those skilled in the art will understand, this mechanism is the direct opposite of the operation of the prior art example shown in FIG. 1D. Furthermore, by not relying on friction (as opposed to the prior art example in FIG. 1C) or spring mechanisms (as opposed to the prior art example in FIG. 1D), embodiments of the invention can provide a more consistent and controlled deployment function, thereby greatly reducing the chance of failure.

[0074] Rotary locking mechanism

[0075] In an embodiment, when the fixing device 10 is in deployment configuration 10B, the anchoring element 12 can be fixedly engaged with the rotating element 14 and prevent rotation in the return direction. In an embodiment, the fixing device 10 may also include a locking structure 31. When the rotating element 14 rotates to a specified angle, the locking structure 31 engages, preventing the rotating element 14 from rotating back toward the width alignment 10A until the user manually disengages the locking structure 31.

[0076] Considering that providing a rotation locking mechanism (e.g., including locking structure 31) may be beneficial, as it means that the user does not need to monitor when the rotating element 14 is fully rotated and actively prevent over-rotation or under-rotation, since at least this embodiment of the fixing device 10 will lock when the appropriate angle is reached. This improves a major problem with the "invisible" implementation of the fixing device 10, such as in the structure 1 obscured by the accessory 3 mounted on or otherwise mounted on the roof (and therefore outside the direct line of sight).

[0077] As used herein, the term “specified angle” refers only to the target rotation angle of the rotating element 14 about axis 18. In some embodiments, the “specified angle” may vary depending on the dimensions of structure 1, particularly the distance between the inner sidewalls 4 and the length L-14 of the rotating element 14.

[0078] In one embodiment and see Figure 7 The locking structure 31 may include a locking groove 30 on one of the rotating element 14 and the anchoring element 12, and a locking region 32 on the other. In at least this embodiment, the locking region 32 is shaped to be received by the locking groove 30 and positioned at the entrance of the locking groove 30 when the rotating element 14 is rotated to a specified angle. See in particular Figure 7 This illustrates the sequence in which the fixing device 10 transitions from the insertion configuration 10A through the intermediate configuration 10C to the deployment configuration 10B. For clarity, in... Figure 7 The deployment mechanism 16 is not shown in the image.

[0079] In the intermediate configuration 10C, the rotating element 14 has undergone rotation to a specified angle (described herein as approximately 90°, but those skilled in the art will understand that this is merely an example), but the locking region 32 has not yet engaged within the locking groove 30. Those skilled in the art will understand that the rotating element 14 and locking region 32 shown in the figures are merely exemplary, and these can take any number of forms without departing from the scope of the invention.

[0080] In another embodiment, at a specified angle, the deployment mechanism 16 can be disengaged or otherwise prevented from causing rotation in the rotating element 14. For example, in embodiments where the deployment mechanism 16 includes a first portion 26 and a second portion 28, the redirecting portion and the second portion can be removed from their engaging contact with each other because any contact between the first portion 26 and the second portion 28 cannot cause rotation. Those skilled in the art will understand that in some embodiments, after disengagement, contact may still exist between the first portion 26 and the second portion 28, or they may otherwise be close to each other, but this contact cannot cause any form of rotation in the rotating element 14. In this arrangement, those skilled in the art will understand that although the first portion 26 and the second portion 28 may be in contact with each other, they are not engaged.

[0081] In embodiments where the deployment mechanism 16 includes a ramp 27 and a compatible element 29, the ramp 27 may terminate proximally to the locking recess 30. At least a portion of the compatible element 29 may be shaped to enter and engage the locking recess 30.

[0082] As described above, the locking structure 31 prevents the rotating element 14 from rotating back towards alignment in the width direction of the insertion configuration 10A until the user manually disengages the locking structure 31. In embodiments where the locking structure 31 includes a locking groove 30 and a locking region 32, disengagement can be achieved by causing a release movement of the rotating element 14 away from the anchoring element 12 along axis 18. Those skilled in the art will understand that the term "release movement" as used herein refers only to the movement of the anchoring element 12 and the rotating element 14 away from each other, and the scope of this disclosure is not limited to which element moves. In some embodiments, the anchoring element 12 may be movable. In some embodiments, the rotating element 14 may be movable. In some embodiments, both the anchoring element 12 and the rotating element 14 may be movable.

[0083] In one embodiment, the releasing motion can remove the locking region 32 from the locking recess 30 and allow the deployment mechanism 16 to re-engage. In some embodiments, this may include a first portion 26 and a second portion 28 in contact with each other. In some alternative embodiments, the first portion 26 and the second portion 28 disengage without losing contact, which allows the contact between the first and second portions to be modified into an engaging contact.

[0084] Return to Insert Configuration

[0085] In embodiments where the fixing device 10 is not intended to provide permanent fixation, it may be advantageous to provide a device (or a third conversion mechanism as described below) that returns the fixing device 10 to the insertion configuration 10A. As those skilled in the art will understand, the insertion configuration 10A may also enable the fixing device 10 to be repositioned along the structure 1 and may also enable the fixing device 10 to be withdrawn from the structure 1 as a whole.

[0086] In one embodiment, the fixing device 10 may include a return device configured to convert the relative movement (i.e., release movement) of the rotating element 14 away from the anchoring element 12 into a rotation of the rotating element 14 toward the width direction, and thus return the fixing device 10 toward the insertion configuration 10A.

[0087] In one embodiment, the release movement between the rotating element 14 and the anchoring element 12 can be caused by a force applied by the user. This embodiment is particularly common in which the rotating element 14 includes a threaded hole 20. Rotation of the threaded fastener 21 in the "release" direction will then drive the rotating element 14 directly away from the anchoring element 12 along axis 18. In an alternative embodiment, such as a T-bolt, the release movement can be caused when the attachment is released from it and the rotating element 14 becomes free to move.

[0088] See Figure 8In the illustrated embodiment, the fixing device 10 may include an external element 34 connected to the anchoring element 12, and a return device 36 is located between the external element 34 and the rotating element 14. See also another embodiment. Figure 9 The figure shows Figure 8 With the lower sides of the external element 34 and the rotating element 14 in a separated state, the return device 36 may include a first return portion 38 on the external element 34 (or a third portion of the constraint element as described below) and a second return portion 40 on the lower side 42 of the rotating element 14 (or a third portion of the fixing element as described below). When the first return portion 38 and the second return portion 40 engage with each other, the relative movement of the external element 34 and the rotating element 14 toward each other (equivalent to the release movement between the anchoring element 12 and the rotating element 14) is at least partially converted into a rotation of the rotating element 14 toward alignment with the width direction of the anchoring element 12 and thus toward the insertion configuration 10A.

[0089] In another embodiment, one of the first return portion 38 and the second return portion 40 is a ramp 33, and the other is a compatible element 35 configured to slide, roll, or otherwise move along the ramp 33. This can have similar characteristics and advantages to the embodiments of the first portion 26 and the second portion 28 discussed earlier. Upon causing a release movement between the rotating element 14 and the anchoring element 12, the compatible element 35 will engage with the ramp 33. Further release movement will press the compatible element 35 into the ramp 33, causing relative movement between the compatible element 35 and the ramp 33, such that one of the compatible element and the ramp slides, rolls, or otherwise moves along the other. This subsequently causes the rotating element 14 to rotate about axis 18.

[0090] As previously stated, those skilled in the art will understand that the above theory is described in relative terms. In embodiments where the second return portion 40 of the rotating element 14 is a ramp 33 (and the first return portion 38 is a compatible element 35), the "compatible element" 35 will not be able to move substantially laterally because the outer element 34 will be restricted by the anchoring element 12 to which it is attached, which impacts one or both opposing flanges 8. However, the compatible element 35 will move relative to the ramp 33. In one embodiment, the ramp 33 is a helical cam. In another embodiment, both the ramp 33 and the compatible element 35 can be helical cams. In another embodiment, the ramp 33 can be a female helical cam, and the compatible element 35 is a male helical cam. In one embodiment, the movement can be a sliding motion between two suitably shaped and / or prepared surfaces. In an alternative embodiment, the compatible element 35 or the ramp 33 may include one or more bearings such that another bearing can roll along it. Other forms of movement may exist or become apparent to those skilled in the art and are considered to fall within the scope of this disclosure.

[0091] In another embodiment, the external element 34 may include an opening 44 to allow trapped debris to be discharged from the retaining device 10, thereby improving the possible resistance of the retaining device returning to the insertion configuration 10A.

[0092] In alternative embodiments and see Figure 10 The return device 36 may include a friction element 46 within the threaded hole 20 of the rotating element 14. In use, the friction element 46 causes the rotating element 14 to rotate in the opposite direction, i.e., to return towards alignment 10A with the width direction of the anchoring element 12 by a primary torque return. When the threaded fastener 21 is loosened, the friction element 46 is engaged thereon and reverses the drive of the deployment mechanism 16, causing the rotating element 14 and the anchoring element 12 to move relatively away from each other and rotate towards alignment 10A in the width direction.

[0093] In embodiments where the deployment mechanism includes a ramp and a compatible structure, the compatible structure can be pushed back along the ramp toward the insertion configuration 10A. As those skilled in the art will understand, in this embodiment, the threaded fastener 21 must protrude sufficiently beyond the friction element 46 before being released to cause the compatible structure to fully return along the ramp, thereby ensuring that the fixing device 10 is fully returned to the insertion configuration 10A.

[0094] In some embodiments, the securing device 10 may include a stop 50 (or at least one stop operable in a releasable configuration as described below), configured to ensure that the rotating element 14 does not rotate beyond alignment with the width direction of the anchoring element 12 during transition from deployment configuration 10B to insertion configuration 10A. The stop 50 may be attached to the anchoring element 12, an external element 34 (if present), or both, or the stop may be formed as part of the anchoring element, an external element (if present), or both. See also Figure 7 Furthermore, in embodiments where the fixing device 10 includes an external element 34, the stop 50 can also be used as a connecting element extending between the anchoring element 12 and the external element 34.

[0095] Further embodiments

[0096] In the embodiments and see Figure 11The anchoring element 12 may include at least one longitudinal engagement portion 52 positioned at one end thereon. The longitudinal engagement portion 52 allows adjacent fasteners 10-1, 10-2 to be connected to each other. This embodiment can provide particular advantage when attachments 3 require multiple attachment points close together, because adjacent fasteners 10-1, 10-2 can be “clamped” or engaged with each other to ensure that both fasteners 10-1, 10-2 are correctly positioned. Those skilled in the art will understand that the length of the anchoring element 12 may need to be varied for different attachments 3, each having double attachment points with different spacing between them, and such variation is within the scope of this disclosure.

[0097] In the embodiments and see Figure 12 When the fixing device 10 is in deployment configuration 10B, the upper surface of the anchoring element 12 is substantially flush with the upper surface of the opposing flange 8. In some embodiments, this allows the user to confirm that the fixing device 10 has been fully converted to deployment configuration 10B. In some embodiments, this also allows the mounting accessory 3 to be mounted flush against the channel flange 8.

[0098] Another aspect of the invention may include a method for securing an article 3 to a groove 6 having a certain groove width and formed by substantially opposing flanges 8 having a first side and a second side, the method comprising the following steps:

[0099] 1. A fixing device 10 is provided, the fixing device including an anchoring element 12, a rotating element 14 and a deployment mechanism 16, the anchoring element 12 being arranged perpendicular to the axis, and the rotating element being mechanically connected to the anchoring element;

[0100] 2. Insert the fixing device 10, which is in the insertion configuration 10A, from the first side through the slot 6 to the second side; and

[0101] 3. A tightening motion is induced between the anchoring element 12 and the rotating element 14 by means of the actuating connection structure 21, which is configured to engage with the article 3 to be fixed;

[0102] The article 3 is fixed against the first side of the groove 6 by the tightening movement and rotation of the rotating element 14, thereby forcing the rotating element 14 against the second side of the flange 8.

[0103] In one embodiment, the anchoring element 12 and the rotating element 14 may have a width less than or equal to the groove width, and the rotating element 14 may have a length greater than the groove width. In another embodiment, the insertion configuration 10A includes the anchoring element 12 and the rotating element 14 arranged along axis 18 such that their widths are aligned, such that the deployment mechanism 16 converts the tightening motion into rotation of the rotating element 14 about axis 18.

[0104] In one embodiment, the connection structure is a threaded fastener 21 extending outward from the article 3, and each of the anchoring element 12 and the rotating element 14 includes a hole 15 extending through it, the hole 15 being aligned with the axis 18 and configured to receive the threaded fastener 21.

[0105] In an alternative embodiment, the connection structure is a threaded fastener extending outward from the rotating element 14, and the anchoring element 12 includes a hole 15 extending through it, the hole 15 being aligned with the axis 18, through which the threaded fastener extends.

[0106] According to another embodiment of the invention (having the various terms as previously described), and see also Figure 13 , Figure 14 and Figure 17 A system for securing an attachment 3 to a structure 1 by means of a fastening device 10 is disclosed. The structure 1 has a groove 6 (or a channel 7 having a groove 6) configured to receive the fastening device 10 therein. It should be understood that the groove 6 or the channel 7 has a longitudinal opening 6 disposed along the longitudinal axis 23.

[0107] The longitudinal opening 6 is partially defined by at least one portion 8 of structure 1 that extends substantially laterally toward the longitudinal axis 23. It will be understood that the lateral direction is orthogonal to the longitudinal axis 23 (and substantially orthogonal to the common axis 18, as will be described below). When structure 1 is fitted with the upward-facing opening 6, the lateral direction is horizontal. Hereinafter, "substantially lateral" will be understood as a functional reference to at least one protruding portion 8 capable of being positioned between the fixing element 14 and the attachment 3 (as will be described below, capable of undergoing relative linear movement toward each other along the common axis 18). Preferably, at least one protruding portion 8 forms an angle of less than 45 degrees with the lateral direction. More preferably, this subtended angle is less than 5 degrees.

[0108] Preferably, the longitudinal opening 6 is defined on either side by two of at least one of the protruding portions 8. More preferably, the two protruding portions 8 are formed by two flanges 8 extending substantially parallel to the longitudinal axis 23. Most preferably, the groove 6 or channel 7 is a channel and the two flanges 8 extend directly toward each other, and the longitudinal axis 23 is arranged between the two flanges.

[0109] See Figure 4 It will be understood that, according to one usage of the term, the groove 6 or channel 7 and the corresponding opening 6 can have a definite length, but are not limited to this interpretation. Conversely, the term groove 6 or channel 7 can also have an indefinite length. Therefore, the fastening device 10 can be used with two different forms of structure 1.

[0110] The fastening device 10 consists of a fixing element 14 and a restraining element 12. The restraining element 12 and the fixing element 14 are interoperable for securing the attachment 3 to the structure 1.

[0111] The fixing element 14 has a surface 24 and the attachment 3 has opposing surfaces 25, each surface being oriented toward at least one protruding portion 8 to apply stress to the at least one protruding portion when it is present therebetween. Preferably, the stress between the surface 24 of the fixing element 14 and the surface 25 of the attachment 3 is compressive. In an alternative embodiment, the system may be configured such that the stress includes shear stress.

[0112] The system includes two conversion mechanisms, each adapted to convert rotational and linear motion along a substantially common axis 18 when the fastening device 10 is received in the slot 6 or channel 7, which is substantially orthogonal to the longitudinal axis 23.

[0113] In this context, the “substantially” common axis 18 will be understood as a potential functional reference for two conversion mechanisms that are offset from each other but still interoperable, wherein a conversion in one conversion mechanism can cause a conversion in the other conversion mechanism (as described below). Furthermore, “substantially orthogonal” should be understood as a functional reference for the ability of the fixing element 14 to translate along the common axis 18 toward the attachment 3 (with at least one protrusion 8 interposed therebetween). This relates to the meaning of “substantially lateral,” since at least one protrusion 8 forms a non-zero angle with the common axis 18, and preferably a normal angle. Preferably, the orthogonality falls within 30 degrees of the normal. More preferably, the deviation of the orthogonality from the normal does not exceed the variation inherent in the tolerances of the components (e.g., any threaded interconnects) (i.e., the design intent that the orthogonality falls within 0 degrees of the normal when the components are arranged at the center of their respective tolerances).

[0114] See Figure 16 The first conversion mechanism in conversion mechanisms 61 and 63 is constituted by the first part 61 of the attachment 3, which engages with the first part 63 of the fixing element 14 and can be manually rotated about the common axis 18 relative to the first part of the fixing element. The second conversion mechanism in conversion mechanisms 65 and 67 is constituted by the second part 65 of the fixing element 14, which engages with the first part 67 of the constraint element 12 and can be manually rotated about the common axis 18 relative to the first part of the constraint element.

[0115] Preferably, the first conversion mechanisms 61, 63 are composed of mating threads 61, 63. More preferably, the first portion 61 of the attachment 3 has external threads, while the first portion 63 of the fixing element 14 has internal threads for engagement with the external threads. Most preferably, the attachment 3 includes a threaded bolt 21, and the surface 25 of the attachment 3 is located below the head of the bolt.

[0116] In an alternative embodiment, the first portion 61 of the attachment 3 has an internal thread, while the first portion 63 of the fixing element 14 has an external thread to mate with the internal thread. In this arrangement, the attachment 3 preferably includes a threaded nut, and the surface 25 of the attachment 3 is formed by the face of the nut.

[0117] It will be understood that the attachment 3 may consist of multiple components. For example, the attachment 3 may consist of a tray and a preferred bolt 21. The preferred bolt 21 may be installed through holes in the tray to secure the tray to the channel 7 of the structure 1 (which is a roof rack). In other words, when the attachment 3 is fastened to the structure 1, another component of the attachment 3 may abut against at least one protruding portion 8 and may be compressed along at least one protruding portion 8 between the surface 24 of the fixing element 14 and the surface 25 of the attachment 3. It will also be understood that the attachment 3 may be integrally formed, and the first portion 61 of the attachment 3 may be physically continuous with the surface 25 of the attachment 3.

[0118] Preferably, the first conversion mechanisms 61 and 63 have first leads, and the second conversion mechanisms 65 and 67 have second leads, with the first leads being smaller than the second leads. More preferably, the size of the first lead is 5 to 25 times smaller than that of the second lead, and even more preferably, the size of the first lead is 10 to 20 times smaller than that of the second lead. The difference in the leads allows the relative rotation of the first conversion mechanisms 61 and 63 and the second conversion mechanisms 65 and 67 to occur at different rates to suit their respective (and cooperating) tightening movements.

[0119] Preferably, the second conversion mechanisms 65 and 67 are composed of face cams. More preferably, the second part 65 of the fixing element 14 is composed of a helical surface 27, and the first part 67 of the restraining element 12 is composed of a follower or a reciprocal helical surface 29.

[0120] Preferably, the first conversion mechanisms 61 and 63 have a first hand advantage and the second conversion mechanisms 65 and 67 have a relatively second hand advantage. More preferably, the first conversion mechanisms 61 and 63 are right-handed and the second conversion mechanisms 65 and 67 are left-handed, so the fastening device 10 can be fastened in a right-handed manner as is customary.

[0121] The second portion 79 of the constraint element 12 is engageable with the slot 6 or channel 7, thereby substantially restraining the rotation of the constraint element 12 about the common axis 18 and relative to the slot 6 or channel 7 when the fastening device 10 is received therein. It should be understood that the constraint element 12 can be easily configured to have a longer dimension than the other, thereby causing interference between the constraint element 12 and the slot 6 or channel 7.

[0122] The fixing element 14 has a first diameter and a second diameter, each substantially orthogonal to a common axis 18, with the first diameter being larger than the second diameter. Preferably, the fixing element 14 is strip-shaped. It should be understood that this allows the fixing element 14 to both be inserted into and engage with the slot 6 or channel 7, and in this respect, "substantially orthogonal" (described below in terms of lateral dimensions) will be understood.

[0123] In a preferred embodiment, the groove 6 or channel 7 is a channel, at least one protruding portion 8 is formed by at least one flange 8 extending substantially parallel to the longitudinal axis 23, and the longitudinal opening 6 leading to the channel 7 has a first lateral dimension smaller than a second lateral dimension of the interior 2 of the channel 7, wherein the first lateral dimension is smaller than a first diameter of the fixing element and larger than a second diameter of the fixing element. Preferably, at least one flange 8 is formed by two such flanges 8 arranged on opposite sides of the channel 7, wherein the first lateral dimension extends between opposite sides of the channel 7.

[0124] The fastening device 10 and the slot 6 or channel 7 are configured such that the fastening device 10 is reversibly switchable between a blocking configuration or state 10B and a releasable configuration or state 10A. In the blocking configuration or state, the fastening device 10 is blocked by interference between the fixing element 14 and at least one protruding portion 8 and cannot be removed from the slot 6 or channel 7. In the releasable configuration or state, the fastening device 10 can be removed from the slot 6 or channel 7 when it is received in the slot 6 or channel 7.

[0125] Preferably, the fixing element 14 in the obstructive configuration 10B is oriented about the common axis 18, wherein the first diameter of the fixing element 14 has a lateral component that is greater than the first lateral dimension and less than the second lateral dimension, and wherein the fixing element 14 in the releasable configuration 10A is oriented about the common axis 18, wherein both the first diameter and the second diameter of the fixing element 14 have corresponding lateral components that are less than the first lateral dimension.

[0126] The first conversion mechanisms 61, 63 and the second conversion mechanisms 65, 67 cooperate to enable a conversion from a releasable configuration 10A to a blocking configuration 10B. Preferably, the first conversion mechanisms 61, 63 and the second conversion mechanisms 65, 67 cooperate to enable a conversion from a releasable configuration 10A to a blocking configuration 10B when the restraining element 12 is at least partially restrained and cannot translate relative to the surface 25 of the attachment 3 (e.g., by means of an elastic biasing element, such as a spring, disposed therebetween) along the common axis 18. More preferably, the restraining element 12 is fully restrained during the conversion (e.g., by abutting against the attachment 3).

[0127] The relationship between the first conversion mechanisms 61 and 63 and the second conversion mechanisms 65 and 67 can be specifically defined by referring to distance or size and rotation angle, such as... Figure 15 As shown, these distances or dimensions, as well as rotation angles, relate to the possibility of hindering the transition between configuration 10B and releasable configuration 10A. For this purpose, when the attachment 3 engages with the surface 24 of the fixing element 14, a first distance 69 is defined between the surface 25 of the attachment 3 and the surface 24 of the fixing element 14, the first distance 69 being parallel to the common axis 18. When the fixing element 14 engages with the restraining element 12, a second distance 71 is also defined between the surface 24 of the fixing element 14 and the restraining element 12, the second distance 71 being parallel to the common axis 18. Finally, when the fastening device 10 is received in the slot 6 or channel 7, an angle 73 is defined between the first diameter and the longitudinal axis 23, the angle 73 being located in a plane orthogonal to the common axis 18.

[0128] The first conversion mechanisms 61 and 63 can undergo relative rotation in the first hand direction, resulting in a corresponding decrease in the first relative linear motion and the first distance 69. This causes a corresponding change in the second relative linear motion and the second distance 71 in the second conversion mechanisms 65 and 67, thereby causing the second conversion mechanisms 65 and 67 to undergo relative rotation in the second hand direction, so that the angle 73 increases from the releasable configuration 10A to the hindering configuration 10B. Preferably, the change in the second distance 71 is a decrease.

[0129] It will be understood that the first linear motion and the second linear motion are relative to the first distance 69 and the second distance 71, respectively, because a reference frame is necessary when defining the motion. Similarly, the rotation in the first and second hand directions is relative to the longitudinal axis 23 of the slot 6 or channel 7. Preferably, the first and second hand directions are opposite directions. In an alternative embodiment, the first and second hand directions are the same direction.

[0131] The angle 73 formed between the first diameter and the longitudinal axis 23 can also be used to describe the relationship between the structure and function of certain features of the constraint element 12. Specifically, the constraint element 12 is preferably provided with at least one stop 50, which is operable in the hindering configuration 10B to constrain the second conversion mechanisms 65, 67 from experiencing a relative rotation in the second hand direction exceeding a first predetermined value of angle 73 between 0 and 90 degrees, and more preferably between 45 and 75 degrees.

[0133] Preferably, the third conversion mechanism 36 is composed of a face cam. Preferably, the third conversion mechanism 36 has the same hand-eye coordination as the second conversion mechanism.

[0134] In other words, in short, a system is provided for securing an attachment to a structure by means of a fastening device, the structure having a groove or channel configured to receive the fastening device therein; the groove or channel having a longitudinal opening disposed along a longitudinal axis, the opening being at least partially defined by at least a portion of the structure extending substantially laterally toward the longitudinal axis; the fastening device comprising a fixing element and a restraining element; and the fixing element having a surface, and the attachment having opposing surfaces, each surface being oriented toward at least one protruding portion for applying stress to at least one protruding portion therebetween; the system includes two switching mechanisms, each adapted to switch along a substantially orthogonal axis when the fastening device is received in the groove or channel. The basic rotational and linear motions along a common axis are described. The first conversion mechanism comprises a first part of an attachment that engages with a first part of a fixing element and is manually rotatable about the common axis relative to the first part of the fixing element. The second conversion mechanism comprises a second part of a fixing element that engages with a first part of a constraint element and is manually rotatable about the common axis relative to the first part of the constraint element.

The fixing element has a first diameter and a second diameter. Both the first and second diameters are substantially perpendicular to the common axis, with the first diameter being larger than the second diameter; wherein the fastening device is prevented from being removed from the slot or channel by interference between the fastening element and at least one protruding portion, and a releasable configuration is provided, wherein the fastening device can be removed from the slot or channel when received in the slot or channel; a first conversion mechanism and a second conversion mechanism cooperate to enable conversion from a releasable configuration to a blocking configuration; when the attachment and the fastening element engage with each other, there is a first distance between the surface of the attachment and the surface of the fastening element, the first distance being parallel to the common axis; when the fastening element and the restraining element engage with each other, there is a second distance between the surface of the fastening element and the restraining element, the second distance being parallel to the common axis. When the fastening device is received in the slot or channel, an angle is formed between the first diameter and the longitudinal axis, the angle being located in a plane orthogonal to the common axis; and wherein the first conversion mechanism can undergo relative rotation along a first hand direction, resulting in a corresponding reduction in the first relative linear motion and the first distance, which causes a corresponding change in the second relative linear motion and the second distance in the second conversion mechanism, thereby causing the second conversion mechanism to undergo relative rotation along a second hand direction, such that the angle increases from a releasable configuration to a hindering configuration; and wherein the first conversion mechanism in the hindering configuration is operable such that at least one protruding portion between the surface of the fastening element and the surface of the attachment can be stressed, thereby securing the attachment to the structure.

[0135] Therefore, a fastening system is provided that can be effectively adapted for a variety of attachments 3 and a variety of structural configurations, including but not limited to roof racks, vehicle interiors, and pallets for multi-purpose vehicles.

[0136] It will be understood that another embodiment may describe the same apparatus as the previous embodiment, although the terminology is different. Therefore, structural and functional features associated with a given term in another embodiment may have the same relevance as the corresponding term in the previously described embodiment, and vice versa.

[0137] In an alternative embodiment, the system includes at least one such conversion mechanism (a second conversion mechanism 65, 67 in the conversion mechanism). Instead of the first conversion mechanisms 61, 63 in the conversion mechanism, the system is provided with a tensioning mechanism adapted to provide a first relative linear motion and a corresponding reduction in the first distance 69, without necessarily providing relative rotation. The tensioning mechanism may be constituted by a cylinder or a pre-tensioned spring.

[0138] Application of the present invention

[0139] Figure 17 An example of a vehicle roof rack in which structure 1 is shown is illustrated, the roof rack including a slot 6 of indeterminate length. A user can attach items 3 at multiple points along the slot 6 and can quickly and easily reconfigure one or more items 3. Specifically, items can be attached to or removed from structure 1 without removing any adjacent items because the fixing or fastening device 10 can be directly inserted into and removed from the slot 6 or channel 7. However, those skilled in the art will understand that the invention is not limited to the uses described above. One or more embodiments of the fixing device 10 can be used in a variety of applications, the only requirement being that the structure includes a longitudinally extending slot suitably adapted to receive the fixing device. To illustrate the adaptability of the fixing device, some non-limiting examples of applications of at least one embodiment of the invention are listed below.

[0140] exist Figure 18 The accompanying drawings shown are a first non-limiting example of the application of the invention, wherein structure 1 is a fixed (or relatively fixed) sports equipment with a net or other fragile, abrasive, or otherwise soft, flexible, or lightweight component attached thereto. Figure 19The specific example shown is a football goal frame, including one or more slots 6 extending to at least a portion of the length of some or all of the posts 80, crossbeams 81, backrests 82, or bases 83, such that a net (not shown) can be attached to the goal frame using one or more fixing devices 10 according to one embodiment of the invention. Those skilled in the art will understand that since components such as nets are often more susceptible to damage from use and weather than the goal frame, it is advantageous to provide users with the ability to quickly and easily attach and remove the net from the goal frame, and to enable or expedite the rapid deployment of the net when the football field is in use, and to enable or expedite subsequent packing and storage when the field is not in use. Other ball sports may also fall within the scope of this non-limiting example; for example, sports such as hockey (both on rink and ice), basketball, netball, tennis, and volleyball all use nets during training and matches, and it would be advantageous to be able to quickly and easily deploy or retrieve these nets. Nets are frequently used in cricket and baseball (and their variants) for pitching and / or batting practice, as are those in golf for putting and chipping practice, and it may be desirable for these nets to be able to be packed away when not in use.

[0141] exist Figure 19 The accompanying drawings, shown, represent a second, non-limiting example of the application of the invention, wherein structure 1 is a street pole and article 3 is to be mounted thereon. One or more slots 6 extend at least a portion of the length of the street pole, allowing article 3 to be secured at a specific height. Article 3 may include street light fixing devices 85 (such as...). Figure 20 (as shown), street signs, road construction signs, temporary signs, or lights, etc. In a particular non-limiting example, items may include decorations or banners (or their mounting devices) that enable maintenance personnel of a particular city or suburb committee to quickly and easily install and remove temporary or seasonal banners (e.g., to commemorate an upcoming holiday), decorations (e.g., Christmas decorations), or other signs (e.g., for advertising an event).

[0142] exist Figure 20The accompanying drawings, shown, represent a third non-limiting example of the application of the invention, wherein structure 1 is an example profile frame consisting of a plurality of profile lengths 88 joined together. Each profile length 88 includes a channel 7 having a slot 6 extending along its length. The profile lengths 88 are capable of being attached to each other in various arrangements and have articles (not shown), such as devices mounted thereon, and the slot 6 and associated structure 1 allow the fixed profile length 88 or article (not shown) to be positioned at any location along the length of the receiving profile length. As those skilled in the art will understand, the ability of the fixing device 10 of the invention to be directly inserted into the slot 6 allows a user to “cover” the ends of the profile length, covering potentially sharp and harmful edges. It also allows assembly machines (including, for example, a plurality of components mounted to the profile frame) to be quickly adjusted or reconfigured, or components to be added to or removed from the assembly machine, without the need for complete disassembly of the assembly machine.

[0143] While the invention has been described with reference to the preferred embodiments above, those skilled in the art will understand that the invention is not limited to these embodiments, but can be embodied in many other forms, variations, and modifications besides those specifically described. The invention includes all such variations and modifications. The invention also includes all steps, features, components, and / or devices that are individually or collectively mentioned or indicated in this specification, as well as any and all combinations or any two or more of these steps or features.

[0144] In this specification, unless the context clearly indicates otherwise, the word "comprising" is not intended to have an exclusive meaning, such as "consisting of only," but rather a non-exclusive meaning of "including at least." This also applies to other forms of the word (such as "comprise"), with corresponding grammatical changes.

[0145] Other definitions of the selected terms used herein can be found in the detailed description of the invention and apply throughout. Unless otherwise defined, all other scientific and technical terms used herein have the same meaning as commonly understood by those skilled in the art.

[0146] Any commitments made in this document should be understood to relate to some embodiments of the invention and are not intended to be commitments regarding the invention in all embodiments. Where commitments exist that are considered applicable to all embodiments of the invention, the applicant / patentee reserves the right to remove them from the specification at a later date, and they do not rely on such commitments for acceptance or subsequent patent grant in any country.
