Technical Field
This application claims priority from us provisional application No. 62/890, 403, filed 2019, 8, 22, the entire contents of which are specifically incorporated herein by reference.
The present disclosure relates to a fastener. More particularly, the present disclosure relates to a fastening clip for a vehicle interior material.
Background
Many vehicles include a seat for either the driver or the occupant or both, or may include a cushion that includes a separate substrate and an interior finish as a cover. Some vehicles have seats that do not require a separate base or trim cover, but many vehicles include both for comfort, aesthetics, and other reasons. Regardless of whether the interior material is cloth, leather, or any other material, manufacturers typically use some type of fastener to secure the interior material to a predetermined portion of the periphery of the base. Some fastening methods are accompanied by the use of wires or other fasteners embedded inside the foam pad. Some substrates and manufacturing methods using other materials may also require new assembly methods and new fasteners.

Detailed Description
The present disclosure can be understood more readily by reference to the following detailed description, examples, drawings, claims, and the foregoing and following description. However, before the present devices, systems, and/or methods are disclosed and described, it is to be understood that the specific devices, systems, and/or methods disclosed are, of course, subject to change unless otherwise indicated and the present disclosure is not limited thereto. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only, and is not intended to be limiting.
The following description is presented as an enabling teaching of best mode and currently known modes of carrying out the invention with respect to apparatus, systems, and/or methods of the present application. Accordingly, those skilled in the relevant art will recognize and appreciate that many changes can be made to the various ways described in this specification, and still obtain the beneficial results of the present disclosure. Several of the desired advantages of the present disclosure can be obtained, as the several features of the present disclosure are selected without utilizing the other features. Thus, those who work in the art recognize that many modifications and adaptations to the present disclosure are possible and can even be desirable in certain circumstances and are a part of the present disclosure. Therefore, the following description is not intended to limit the present disclosure, but is provided as an illustration for explaining the principle thereof.
Throughout, for example, reference to an amount of a particular element can include more than two of such elements, unless expressly indicated otherwise from the context. Any one of the elements described in the present specification may be a first element of such an element, a second element of such an element, or the like (for example, when only "component" is referred to, the first component and the second component are also referred to).
Ranges can be expressed herein as from a value labeled "about" for one particular value, and/or to a value labeled "about" for another particular value. When such a range is expressed, another manner includes from the one particular value, and/or to the other particular value. Similarly, when values are expressed as approximations, by use of the antecedent "about" or "substantially," it will be understood that the particular value forms another aspect. It will be further understood that the endpoints of each of the ranges are significant at two points: related to other endpoints, and, in addition, unrelated to other endpoints.
For purposes of this disclosure, dimensions determined to be about X or substantially X in a material property, or a particular measurement scale, are determined within the following ranges: the range is between a value obtained by adding X to the upper tolerance of the industrial standard for the specified measurement value and a value obtained by subtracting X from the lower tolerance of the industrial standard for the specified measurement value. The tolerances may vary from material to material, process to process, and model to model, and therefore, the tolerance of a particular measured value for a particular component may also be included within the tolerance range.
As used herein, the term "arbitrary" or "arbitrary" means that a phenomenon or a situation described later may or may not occur, and that an instance in which the phenomenon or the situation occurs and an instance in which the phenomenon or the situation does not occur are included in the description.
As used herein, the word "or" refers to any one element of a particular list and also includes any combination of elements of that list. As used herein, a statement that "at least one of a and B" means "only a, only B, or both a and B," but "one of a and B" means "a or B.
Disclosed are components that can be used to implement the disclosed methods and systems. The above-described constituent elements and other constituent elements are disclosed herein, and when combinations, partial assemblies, interactions, groups, and the like of these constituent elements are disclosed, specific references to various individual combinations and assembly combinations thereof and various modes of substitution are not explicitly disclosed, but are each specifically studied and described for all methods and systems, respectively, from no point of view. This applies to all manner of the present application including, without limitation, the steps of the disclosed methods. Therefore, when there are a variety of additional steps that can be performed, it goes without saying that each of these additional steps can be performed together with a specific mode or a combination of modes of the disclosed method.
The cover fastening clip 10 will be described below based on the X, Y, Z-oriented coordinate axis shown in the drawing. The X-axis direction may be referred to as a left-right direction or a horizontal direction. For example, as shown in fig. 1, the X-axis direction coincides with the extending direction of a hook 600 (shown in fig. 6) provided in a hook securing chamber 280 (both shown in fig. 6) of the clip 100.
The Y-axis direction is orthogonal to the X-axis direction (left-right direction) and the Z-axis direction (up-down direction), and may be referred to as a front-back direction, a lateral direction, or a longitudinal direction of the clip 100 from the first side end 107 (shown in fig. 1) to the second side end 108 (shown in fig. 1). The surface of the construction element parallel to the front-rear direction may be referred to as a side surface.
The vertical direction is orthogonal to the X-axis direction and the Y-axis direction, and is generally a Z-axis direction that coincides with the height of the clip 100. For example, a direction in which the hook 600 is inserted into the gap 168 of the clip 100 to be locked by the clip 100 may be referred to as a Z-axis direction. In addition, the up-down direction may coincide with a direction perpendicular to the surface of the cover 1010 (shown in fig. 10), which cover 1010 extends over, above, or across the base 900 (shown in fig. 9).
In one form, methods, systems, implements, various devices associated with a seat cover securing clip are disclosed herein. In one aspect, a clip can include a base and a pair of walls.
Fig. 1 is a top perspective view of a clip 100 in one form of the present disclosure. As shown, the clip 100 may include a base 110 and a pair of wall portions 150a, 150 b. The base 110 is also a mounting portion, leg portion, platform, or bottom portion of the clip 100. The base 110 may define a bottom surface 111 (illustrated in fig. 2) and a top surface 112 spaced apart from the bottom surface 111. In several ways, the base 110 may be solid as shown. In other ways, as described later, the base 110 may define more than one aperture or cavity (e.g., without limitation, illustrated in fig. 17B) in order to cut costs and weight, or to provide other advantages. For example, and without limitation, one or more corners 119 of base 110 may define an edge such as an arc or chamfer. The geometric center of the base 110 may define a centerline axis 101 in the Z-axis direction.
A pair of wall portions 150a, 150b extend from the base 110 defining inner surfaces 151a, 151b (151b is illustrated in fig. 2) and outer surfaces 152a, 152b (152a is illustrated in fig. 2). The first and second wall portions 150a and 150b, respectively, may extend from the top surface 112 of the base 110. The wall portions 150a, 150b may define respective base end portions 153a, 153b and respective tip end portions 154a, 154b proximate the base 110, respectively. The wall portions 150a, 150b may also define respective hooks or catches 160a, 160b at the respective distal end portions 154a, 154 b. The first and second latch hooks 160a and 160b may define a gap 168 therebetween. Wall portions 150a, 150b may also define respective guide rails 170a, 170b at positions offset from corresponding distal end portions 154a, 154b toward base end portions 153a, 153b, respectively. This location may define an offset distance 177, which offset distance 177 may be determined by and beneficial for the reasons described subsequently. The latch hooks 160a, 160b and the guide rails 170a, 170b may extend from the respective inner surfaces 151a, 151 b. The respective fins 190a, 190b of each wall portion 150a, 150b may extend from the respective outer surface 152a, 152 b. In several ways, as shown, the fins 190a, 190b can define a width 197 (shown in FIG. 3) in the X-axis direction that is less than the entire width of the base members 110a, 110b and wall portions 150a, 150b, respectively, in that direction. In other embodiments, two or more of the above-described elements may define the same width. In several ways, the clip 100 may not include fins, or may include one fin 190a, 190b or more than two fins 190a, 190 b.
Fig. 2 is an end view of the clip 100. As shown, the base 110 may define a constant thickness T except in the vicinity of the wall portions 150a, 150 b. In several ways, the fins 190a, 190b may be angled at angles 270a, 270b downward from the horizontal or Y-axis direction, as shown. The pair of wall portions 150a, 150b may also include any portion thereof and may together define the hook assurance chamber 280 and the expansion chamber 290. As shown, base ends 153a, 153b of the walls 150a, 150b may intersect the top surface 112 of the base 110 at the outer surfaces 152a, 152b, and a portion or at least the base ends 153a, 153b of the walls 150a, 150b may be offset from the top surface 112 at the inner surfaces 151a, 151b by an offset distance 207. The intersection between the base 110 and the wall portions 150a, 150b may define a transition 210, and the transition 210 may have a rounded or chamfered portion of a size that may reduce the stress generated upon outward flexing of the wall portions 150a, 150b, as described later.
Fig. 3 is a top view of clip 100. In several ways, the base 110 may be rectangular as shown when viewed from above or (as shown in FIG. 5) from below. In another embodiment, the clip may have a shape other than a rectangular shape, such as a circular shape (not shown) or another shape, in order to maximize stability while minimizing material usage (by preventing rotation of the clip 100). As shown, the clip 100 can define a notch 380 extending from the bottom surface 111 (shown in fig. 5) on the base 110 at a location between the first wall portion 150a and the second wall portion 150 b. In several ways, the indentations 380 may be through holes, as shown, or may define a closed shape. In other ways, the notch 380 may be a cut-out, or may define an open shape. In several ways, as shown, the notch 380 can define a rectangular shape. In another embodiment, the notch 380 may be configured to define a shape other than a rectangle of any size and to accommodate a tool such as a removal tool 1200 (shown in fig. 12). In order to facilitate engagement between the removal tool 1200 and the wall portions 150a, 150b, a portion of one of the first wall portion 150a and the second wall portion 150b may intersect a plane defined by an edge portion of the notch 380 and extending in a direction parallel to the centerline axis 101, i.e., the axis of the notch 380 of the clip 100. As shown, the notch 380 may not be defined on either of the first and second ends 105, 106 of the clip, but rather between the first and second ends 105, 106 of the clip. Additionally, the fins 190a, 190b may each define a width 197.
Fig. 4 is a side view of the clip 100. As shown, first end 105 and second end 106 may each be angled or sloped inward toward centerline axis 101 at an angle 470. The clip is shown as symmetrical about a centerline axis 101, but in some versions the clip 100 may alternatively be asymmetrical when viewed from more than one direction. In order to facilitate the manufacture of the clip 100 by an injection molding process or the like, the clip 100 may define a tapered surface or a draft surface in one or more directions of the X-axis, Y-axis, or Z-axis, and introducing a draft angle is beneficial to the ease of manufacture.
Fig. 5 is a bottom view of the clip 100. The base 110 and the clip 100 collectively further define a first lateral end 107 and a second lateral end 108, the first and second lateral ends 107 and 108 extending from the first end 105 to the second end 106, respectively. As shown, the notch 380 may define a length L in the X-axis direction and a width W in the Y-axis direction. The clip 100 can define notched sidewall portions 510a, 510b, which themselves can be arbitrarily angled with respect to the centerline axis 101. Including such, the notch 380 may be tapered like the wall portions 150a, 150b at a portion of the wall portions 150a, 150b defining the notch 380. Accordingly, the width W of the notch 380 in the Y-axis direction may be wider in the vicinity of the bottom surface 111 than at a position offset from the bottom surface 111 in the Z-axis direction.
Fig. 6 is an end view of the CLIP 100 to which the hook 600 is assembled, and the hook 600 may be, for example, but not limited to, a hook like a member for fastening a part of a product by EZ-CLIP (registered trademark) of YKK corporation. The clip 100 can flex or deform between an unflexed state (shape 601 formed by the solid lines) and a flexed state (shape 602 formed by the dashed lines). This deflection may be due to the following forces: the hook 600 applies an outward force to the distal end portions 154a, 154b of the wall portions 150a, 150b of the clip 100, and opens the gap 168 (shown in fig. 1) or increases the size of the gap 168. The conical main body 610 of the hook 600 and the side surfaces defined thereby can press the conical latch hooks 160a, 160b, in particular the entry surfaces 654a, 654b of the respective latch hooks 160a, 160 b. As shown, the main body 610 of the hook 600 is not accommodated in the expansion chamber 290, but in the hook securing chamber 280, and is held in a contact state with the hook hooks 160a, 160b by the guide rails 170a, 170 b. The flange 620 of the hook enables easy insertion of the hook 600 into the clip 100 by providing a surface for the hook 600 to be more easily pressed into on either side of the band 670 of the hook 600. As will be described later, an installation tool 2200 (shown in fig. 22) that can be an insertion tool facilitates installation of the hook 600 to the clip 100. As shown, each fin 190a, 190b may taper in an outward direction relative to centerline axis 101. More specifically, as shown, the bottom side of each of the fins 190a, 190b may be horizontal to the base 110 in the undeflected state, but the upper side of each of the fins 190a, 190b may be inclined in the same state. The illustration is made larger than necessary to ensure passage of the chamber 280 from the gap 168 to the hook 600, and in this regard, the degree of deflection shown in fig. 6 may be considered exaggerated.
Fig. 7 is a top perspective view of a clip 100 according to another aspect of the present disclosure. Specifically, the tab 710a (and the opposite tab not shown) may extend from the inner surfaces 151a, 151b or from either of the inner surfaces 151a, 151b, and may be sized to engage with either of a plurality of recessed portions 810 of the hook 600 (shown on the second side of the hook 600 in fig. 8, but the recessed portions may likewise be defined on the first side of the hook 600), or may be otherwise configured as such. As shown, the width of the clip 100 measured along the X-axis from the first end 105 to the second end 106 is less than, or may be even more than, the width measured from the first side end 107 to the second side end 108, as compared to the clip 100 shown in the previous figures.
Fig. 8 is a side view showing the clip 100 and hook 600 assembly, which is locked arbitrarily in the X-axis direction by the above-described tab such as the tab 710a (shown in fig. 7) and locked inside the hook securing chamber 280 in the Z-axis direction. Any one of the plurality of concave portions 810 of the main body 610 can be engaged with the above-described tab such as the tab 710a, and therefore, the left-right position of the hook 600 in the clip 100 can be adjusted as desired in the X-axis direction before the complete engagement in the Z-axis direction in several ways, and in any case, can be locked in a desired position in any one or all of the X-axis, Y-axis, and Z-axis directions thereafter.
Fig. 9 is a partial cross-sectional end view of the clip 100 before the clip 100 is attached to the base 900 according to an embodiment of the present disclosure, and is a view showing a part of the base 900 of a seat cushion such as, for example, but not limited to, a seat cushion pad of a vehicle seat (not shown) or a seat back pad of a vehicle seat. The base 900 may define a bottom surface 911 and a top surface 912, and may include a body 910 that further defines a plurality of openings 980 extending from the bottom surface 911 to the top surface 912.
In several aspects, the opening 980 may be a notch or hole that may be formed due to, for example, removal or deformation of material of the base 900 (thermally based, mechanically based, or based on other methods). In another embodiment, the opening 980 may be a slit formed by cutting (e.g., without limitation, mechanically shearing and/or by liquid or gas energy) the material of the base 900 so that the clip 100 passes through the opening, for example, due to a change in the position of the material of the base 900 surrounding the opening 980. The slits may define one-dimensional openings (e.g., small holes formed without removing material of the substrate 900, forming openings having only a single dimension across the thickness of the material), two-dimensional openings (e.g., defining dimensions across the thickness of the material, and dimensions across the material), or three-dimensional openings (e.g., openings having at least partially both a length and a width across the material, and defining dimensions across the thickness of the material). The opening 980 may also be defined by any shape or size.
In several ways, as shown, a lower portion 982 of each opening 980 defined at the bottom surface 911 of the base 900 can have a smaller width or diameter than an upper portion 984 of the same opening 980 defined at the top surface 912. In various ways, the lower portion 982 of the opening 980 may be square or circular or any other shape to correspond to one shape or other shape of the clip 100. In any case, the shoulder surface 986 is provided by a change between the lower portion 982 and the upper portion 984 of the opening 980, and the shoulder surface 986 captures and holds the fins 190a, 190b of the clip 100, thereby reliably maintaining the position of the clip 100 after assembly. In several aspects, upper portion 984 is a recessed portion extending between a plurality of openings 980 and is capable of accommodating the extended length of hook 600. As shown, the centerline axis 101 of the clip 100 may coincide with the opening centerline 901 of the opening 980. The clip 100 may be arranged with respect to the base 900 such that the distal end portions 154a, 154b of the wall portions 150a, 150b of the clip 100 and the top surface 112 of the base 110 face the bottom surface 911 of the base 900.
Fig. 10 is a partial cross-sectional end view of clip 100 and base 900 after installation of clip 100 to base 900 and before installation or insertion of hook 600 into clip 100. As shown, the top surface 112 of the base 110 is coplanar with or adjacent to the bottom surface 911 of the body 910, and the presence of the base 110 prevents further insertion of the clip 100 from the bottom. The fins 190a, 190b assist in locking the clip 100 inside the opening 980, preventing the clip 100 from falling out of the opening 980. Illustrated in a simplified manner, hook 600 may be mounted or secured to cover 1010, for example, without limitation, with more than one sewn joint. The cover 1010, which may be a sleeve, may be formed from or define a single panel and may be used to encase the substrate 900. As shown, the vertical material clearance distance 1090 measured from the top surface 112 of the base to the nearest portion of one of the fins 190a, 190b may define a maximum clearance for receiving and locking a portion of the substrate 900 in a predetermined position relative to the clip 100.
As shown, the base 110 of the clip 100 may engage, face, contact, or be disposed on a surface of the base 900 of the assembly 1000 that is the bottom surface 911, or a surface offset from the bottom surface 911 and facing in a direction opposite the top surface 912. The fins 190a, 190b of the first wall portion 150a and the second wall portion 150b may engage, face, or contact a surface of the base 900 of the assembly 1000 that faces in the same direction as the top surface 912 and may be a shoulder surface 986, or may be disposed on the surface.
Fig. 11 is a partial cross-sectional end view of clip 100 and base 900 after installation of clip 100 to base 900 and after installation of hook 600 in a restrained state to clip 100 to form assembly 1000. The cover 1010 is shown in a relaxed state over the base 900, but when the cover 1010 is secured by assembly of the hook 600 with the other examples of the clip 100, the cover 1010 is in a desired state of tension or close contact with respect to the top surface 912 and other surfaces of the base 900. As such, the assembly 1000 may include a base 900 disposed between the cover 1010 and the base 110 of the clip 100, and may include each cover 1010 and more than one clip 100.
More specifically, the method of assembling the assembly 1000 may comprise the steps of: inserting the clip 100 into one of the plurality of openings 980; and a step of inserting the hook 600 toward a gap 168 (illustrated in fig. 1) of the clip 100 defined between the first latch hook 160a (illustrated in fig. 1) and the second latch hook 160b (illustrated in fig. 1). When clip 100 is inserted into one of the plurality of openings 980, a sound, such as, for example, without limitation, an audible "pop" can be generated to indicate complete engagement of clip 100 with each opening 980 of base 900.
FIG. 12 is a top perspective view of the assembly of clip 100 and hanger 600 after removal tool 1200 has been inserted into clip 100 from the bottom via notch 380. As shown, the removal tool 1200 may include a handle 1210 and a shaft 1220 extending from the handle 1210. The handle 1210 may have a circular cross-section or may be provided so that a hand of a user (who may be an assembly operator) can comfortably hold the handle, and the shaft 1220 may have sufficient strength so as not to be broken during use, and may be a shaft that does not obstruct the user. As shown, the handle may have a capsule shape defining a central bobbin 1201.
For example, without limitation, it may be desirable to detach hook 600 from clip 100 in any of several situations, such as after two components have been mistakenly assembled during the manufacturing process, after more than one component has been found to be defective after assembly, and during maintenance or repair operations for accessories (e.g., seat heater wires) that are concealed inside cover 1010. Since cover 1010 may be made of expensive materials and require a large amount of labor to manufacture, the cost of cover 1010 is high, and therefore, it would be beneficial if the components could be disassembled by disassembling hook 600. Not only the cover 1010 but also other optional accessories such as heaters, control lines, air bag components, etc. are assembled as part of the seat, and therefore the assembly 1000 (shown in fig. 11) itself may become more expensive. Even in the case where the hook 600 and one or more clips become mismatched in assembly, the unmating tool 1200 may be used to simply disassemble the mismatched components and then assemble them.
More specifically, the method of detaching the hanger 600 from the clip 100 may comprise the steps of: inserting the removal tool 1200 into the notch 380 defined in the base 110 of the clip 100 in the Z-axis direction; a step of expanding first wall portion 150a and second wall portion 150b to increase the size of gap 168 (illustrated in fig. 1) between first wall portion 150a and second wall portion 150 b; and a step of detaching the hook 600 from the clip 100.
Fig. 13-15 show various exemplary shapes of the removal tool 1200 provided with a specifically sized and shaped notch 380, which itself may be adjusted to a desired shape, and may be tapered as shown. The design of the clip 100 and removal tool 1200 and the relationship between the two components may be reflected in the combination of the illustrated shapes shown in fig. 13-15. FIG. 13 is a cross-sectional view of portions of the clip 100, the hanger 600, and the removal tool 1200. As shown, the top end 1310 of the removal tool 1200 has a width at the bottom surface 111 of the base 110 that is narrower than the width W of the notch 380 in the Y-axis direction and a width at a location spaced from the bottom surface 111 that is wider than the width of the notch 380. The gap 168 between the latch hooks 160a, 160b is opened to the extent that the wall portions 150a, 150b of the clip 100 separate or move away from each other due to the pinching between the tip 1310 and the tapered notched side wall portions 510a, 510 b: it is sufficient to enable the disassembly of the hook 600 in at least the Z-axis direction, the disassembly of the hook 600 in the X-axis direction depending on the degree of insertion of the disassembly tool 1200 and whether other clips are still being assembled. As shown, the body 1305, and more specifically the tip 1310, of the removal tool 1200 is in contact with the clip during the removal operation, but is not necessarily in contact with the hook 600 itself.
Fig. 14 shows a removal tool 1200 in combination with the same clip 100, in another aspect of the present disclosure. As shown, the narrow portion 1420 of the top end 1310 of the removal tool 1200 extends upward from the wide portion 1410 (as has been shown in the shape of fig. 13) to the hook 600, so that if the wide portion 1410 of the removal tool 1200 expands the wall portions 150a, 150b apart, the narrow portion 1420 contacts and pushes the hook 600 out of the hook assurance chamber 280.
Fig. 15 shows a removal tool 1200 according to still another embodiment of the present disclosure. As shown, a portion 1430 of the removal tool 1200, and more particularly the tip 1310 thereof, can reach the notch 380 defined in the clip 100 and can contact the hook 600 in such a manner that the tip 1310 of the removal tool 1200 is centered between the walls 150a, 150b and expands between the walls 150a, 150b by pressing the rails 170a, 170b outwardly to expand the rails 170a, 170b sufficiently to remove the hook 600. Such flaring of the walls 150a, 150b at the rails 170a, 170b may be facilitated by defining an inclined or tapered lower side of the rails 170a, 170b as shown.
Fig. 16A and 16B illustrate another version of a removal tool 1200 of the present disclosure. As shown in fig. 16A, the shaft 1220 can include a first portion 1510 defining sides 1512a, 1512b and a second portion 1520 defining sides 1522a, 1522b of the tip 1310. Sides 1522a, 1522b, or portions of sides 1522a, 1522b, respectively, may be inclined at an angle 1540 relative to a centerline axis of shaft 1220. The sides 1522a, 1522b of the second portion 1520 may have an arc with radii R1 and R2 as shown. As shown in fig. 16B, the shaft 1220 of the removal tool 1200 may define an X-axis direction shaft thickness 1570, which shaft thickness 1570 may remain constant up and down the shaft 1220.
In several ways, as shown in fig. 12, the centerline axis 1201 of the handle 1210 may coincide with the X-axis direction of the clip 100 when the removal tool 1200 is inserted to remove the hanger 600. In another way, in the handle 1210 shown in fig. 16A and 16B, when the hook 600 is removed by inserting the removal tool 1200, the center line axis 1201 of the handle 1210 may coincide with the Y-axis direction of the clip 100. In the latter case, the tapered shaft 1220 of the removal tool 1200 is substantially coincident with, but not necessarily collides with, the notch side wall portions 510a, 510b of the notch 380. Alternatively, the bulbous second portion 1520 of the shaft 1220 can reach the catch 600 to push the rails 170a, 170b apart, leaving the gap 168 (shown in FIG. 1) open. Also, the neck defined by the intersection of the first portion 1510 and the second portion 1520 is constrained by the rails 170a, 170b, thereby benefiting from preventing further movement of the shaft 1220 toward the clip 100 and from preventing the possibility of jamming. In various ways including the removal tool 1200 shown in fig. 16A and 16B, the engagement of the removal tool 1200 with the clip 100 sufficient to remove the hook 600 may be accompanied by a clicking sound or click sound indicating proper engagement of the removal tool 1200 and removal of the clip 100.
Fig. 17A to 17I show a clip 100 according to another embodiment of the present disclosure. Fig. 17A is a top perspective view of the clip 100. As shown, the wall portions 150a, 150b may extend from the base 110. Also as shown, fins 190a, 190b may extend from wall portions 150a, 150b, respectively. Notches 380a, 380B (380B is shown in fig. 17B) defining respective notch side wall portions 510a, 510B (510B is shown in fig. 17B) can extend a distance D (shown in fig. 17B) from the first and second ends 105, 106 (shown in fig. 17B) of the clip 100, respectively. At least a portion of the surface defined by the notched sidewall portions 510a, 510b, respectively, may face either of the directions X, Y, Z, or coincide with either of the directions X, Y, Z. A portion of the base 110 extending between the wall portions 150a, 150b can at least partially define the notches 380a, 380b or the notch 380, and the notch 380 itself can include the notches 380a, 380 b. The same portion of the base 110 may define a cross member 570 (illustrated in fig. 17B), the cross member 570 forming a portion of the base 110 and may define a width 577 (illustrated in fig. 17E) in the X-axis direction.
Fig. 17B is a bottom perspective view of the clip 100 of fig. 17A. In several ways, the base 110 may define a base cavity 118 formed by the ribs 114, 116 at the bottom surface 111. By defining the base cavity 118 in the base 110, strength can be maintained (due to the presence of the angularly intersecting ribs 114, 116), while on the other hand the weight of the base 110 (due to the removal of material from each base cavity 118) can be minimized, thus minimizing the overall weight of the clip 100. In several ways, the susceptor chamber 118 may be a pocket that does not extend completely over the susceptor 110. In other approaches, the base cavity 118 may extend completely over the base 110 from the bottom surface 111 to the top surface 112.
Fig. 17C is a cross-sectional view of the clip 100 of fig. 17A at line 17C-17C of fig. 17D. In several ways, the maximum value of the thickness T of the base 110 may be slightly tapered in thickness in a direction outward away from the nearest wall portions 150a, 150b, as shown. As shown, a portion of the inner surfaces 151a, 151b or outer surfaces 152a, 152b may form an angle with respect to the bottom surface 111 or top surface 112 of the base 110 that varies from a base end portion 153a, 153b of the wall portions 150a, 150b, respectively, to a tip end portion 154a, 154b of the wall portions 150a, 150b, respectively. As shown in fig. 17B, wall portions 150a, 150B may be separated by a distance substantially equal to a width W (shown in fig. 17E) of notches 380a, 380B (shown in fig. 17A and 17B) near base end portions 153a, 153B, while portions near the tip end portions 154a, 154B may approach each other between the tip end portions 154a, 154B and the base end portions 153a, 153B for the wall portions 150a, 150B or portions thereof. The wide opening between the wall portions 150a, 150b in the vicinity of the base 110 can facilitate the insertion of the removal tool 1200 (shown in fig. 17F), and at the same time, can increase the surface area of the respective inclined portions 1751a, 1751b of the inner surfaces 151a, 151b pressed by the removal tool 1200, and can release the hook 600 (shown in fig. 6) by separating the wall portions 150a, 150b by such pressing. Such an increase in surface area may result in reduced friction and binding between the removal tool 1200 and the clip 100. In addition, as shown, the hook securing chamber 280 of the clip 100 may be shaped to conform to the shape of the fitting portion of the hook 600 (shown in fig. 6), and as such, the hook 600 may also be fixed to the inside of the hook securing chamber 280, and the risk of movement and rattling of the hook, which has the potential to cause generation of audible noise for the user, may be eliminated or reduced.
Fig. 17D is a side view of the clip 100 of fig. 17A. As shown, the width 157 of the wall portions 150a, 150b of the clip 100 is smaller than the width of the base 110 in the X-axis direction.
Fig. 17E is a top view of the clip 100 of fig. 17A. As shown, the width W and length L of the notches 380a, 380b may be measured, or the depth D of each notch 380a, 380b may be measured. In several ways, as shown, the width 197 of at least one of the fins 190a, 190b in the X-axis direction can vary along the Y-axis direction over the extension of each fin 190a, 190b from the base portion 193a, 193b of the fin 190a, 190b to the tip portion 194a, 194b of the fin 190a, 190 b. For example and without limitation, at least one of the fins 190a, 190b may have a T-shape as shown. If the width 197 at the tip portion 194a is increased, the rotation of the clip 100 about the Y-axis direction can be minimized, and the weight of the fins 190a, 190b can be minimized, thereby minimizing the overall weight of the clip 100. Since the wall portions 150a and 150b are visible above the notches 380a and 380b, respectively, they can be engaged with a removal tool 1200 (shown in fig. 17F).
Fig. 17F is a bottom perspective view of the clip 100 of fig. 17A after the removal tool 1200 has been inserted into the clip 100 from the bottom.

The tip 1310 of the shaft 1220 can include a first lateral portion 1313 and a second lateral portion 1314, which first and second lateral portions 1313, 1314 can define a forked tip 1310 that defines a tool chamber 1318 therebetween. The tool chamber 1318 may be sized to receive the cross member 570 (shown in fig. 17B) of the clip 100, and the top end 1310 of the removal tool 1200 may have a depth sufficient to spread the walls 150a, 150B (shown in fig. 17F) apart to push the hook 600 (shown in fig. 6) from the clip 100. More specifically, the second portion 1520 of the shaft 1220 may press the wall portions 150a, 150b to expand the wall portions 150a, 150b, and the third portion 1530 may press the hook 600.
Fig. 18A to 18I show a clip 100 according to still another embodiment of the present disclosure. Fig. 18A is a top perspective view of a clip according to another aspect of the present disclosure. As shown, base 110 may include base members 110a and 110b, which may be joined by base member 110 c. In several ways, as described above, base members 110a, 110b, 110c of base 110 may be oriented in a single plane. In other ways, as shown, at least one of the base members 110a, 110b, 110c of the base 110 may be arranged in a different plane than the other base members 110a, 110b, 110 c. Clip 100 may include gussets 180a, 180B (180a is illustrated in fig. 18B) extending between base members 110a, 110B and respective wall portions 150a, 150B to reinforce them. Clip 100 may include a gusset 180C (shown in fig. 18C) extending between each base member 110a and base member 110C to reinforce them, and a gusset 180d (shown in fig. 18B) extending between each base member 110B and base member 110C to reinforce them. As shown, the notch 380, illustrated as a through hole, may be circular and its centerline axis may coincide with centerline axis 101.
Fig. 18B is an end view of the clip 100 of fig. 18A. The fins 190a, 190b may taper from the base portions 193a, 193b to the respective end portions 194a, 194b, respectively. Vertical material clearance distance 1090 may be further reduced by lifting base members 110a, 110b toward respective fins 190a, 190 b.
Fig. 18C and 18D are first and second side views, respectively, of the clip 100. As shown, the fins 190a, 190b taper from the bottom end to the upper end of each fin 190a, 190b, the bottom ends of the fins 190a, 190b being proximate to the base 110, and the upper ends of the fins 190a, 190b being distal from the base 110.
Fig. 18E and 18F are top and bottom views of clip 100. As shown, the centers of the fins 190a, 190b and the centers of the gussets 180a, 180b, 180c, 180d can coincide with each other, and additionally, can coincide with the center of the notch 380, and can coincide with the transverse axis or transverse centerline 102.
Fig. 18G shows a base member 110c of a clip 100 according to still another embodiment of the present disclosure. The notches 380a, 380b are separated by a cross member 570 and are bounded by another portion of the base member 110c or closed at an outer edge. Without the cross member 570, the notch 380 may define a rectangular or substantially rectangular shape.
Fig. 18H and 18I illustrate a clip 100 according to yet another aspect of the present disclosure in which the fins 190a, 190b are offset from each other along the X-axis direction. Fig. 18H is a top perspective view of clip 100 without notch 380 included in base member 110 c. To remove the hanger 600 (shown in fig. 6) from the clip 100 shown in fig. 18H, a removal tool 1200 (shown in fig. 19A) may be inserted from the X-axis direction into the expansion chamber 290, which expansion chamber 290 may be defined between the base 110 of the clip 100 and the hanger ensuring chamber 280 configured to accommodate the hanger 600 (or between the base 110 of the clip 100 and the hanger 600 from either the upper or lower direction of the base 110 of the clip 100). Fig. 18I is a plan view of the clip of fig. 18H showing the offset distance 196 between the centers 192a and 192b of the fins 190a and 190b with respect to the transverse center line 102, and is useful for fixing the clip 100 to the inside of the base 900 more favorably without coming out of the opening 980, including a case where a part of the opening 980 spaced apart from the centerline axis 101 or the transverse center line 102 is better fixed or held than a part of the opening 980 located in the vicinity of the centerline axis 101 or the transverse center line 102.
As shown in fig. 19A and 19B, vertical material clearance distance 1090 may be further reduced by increasing offset distance 1080 (shown in fig. 18B) that base member 110c is offset from base members 110a, 110B of base 110 relative to top surface 112. For example and without limitation, the vertical material clearance distance 1090 is as short as 2 millimeters or less and the overall height of the clip 100 is as small as 12-14 millimeters. More specifically, vertical material clearance distance 1090 is 20 millimeters or less in several ways, vertical material clearance distance 1090 is 15 millimeters or less in several ways, vertical material clearance distance 1090 is 10 millimeters or less in several ways, vertical material clearance distance 1090 is 7.5 millimeters or less in several ways, vertical material clearance distance 1090 is 5 millimeters or less in several ways, vertical material clearance distance 1090 is 4 millimeters or less in several ways, and vertical material clearance distance 1090 is 2.5 millimeters or less in several ways. The vertical material clearance distance 1090 may also be greater than 20 millimeters in several ways.
Fig. 19A is a side perspective view of clip 100 including removal tool 1200 inserted into clip 100 from the bottom along centerline axis 101. Fig. 19B is a side perspective view of the clip of fig. 19A without the gussets including a constant thickness fin according to yet another aspect of the present disclosure, including a removal tool 1200 inserted further into the clip 100 from the bottom along the centerline axis 101.
Fig. 20A to 20D show a clip 100 according to still another embodiment of the present disclosure. As shown in fig. 20A, which is a front perspective view of the clip 100, one or both ends 105, 106 of the base 110, and specifically the base member 110c, may define a cavity or recess 2080. In some aspects, if the recess 2080 is defined in the clip 100, the material required to form the clip 100 can be reduced, and therefore the weight and cost of the clip 100 can be reduced. In several ways, if the recess 2080 is defined in the clip 100, the following features can be obtained: in an automated assembly process, automated equipment such as tools or robots may be used to hold, orient, and move the clip 100 during assembly to the hanger 600 and/or other surrounding structure of the clip. In some aspects, if the concave portion 2080 is defined in the clip 100, the clip 100 itself can be easily manufactured by maintaining the overall size of the clip 100 while adjusting the thickness of the surrounding portion of the clip 100 to a desired value.
As shown in fig. 20B, which is a cross-sectional view of the clip 100 at the line 20B-20B of fig. 20C, the thickness 2010 of each wall portion 150a, 150B in the Y-axis direction is larger at or near each base end portion 153a, 153B and below each rail 170a, 170B than at or near each tip end portion 154a, 154B and at or above each rail 170a, 170B. The inner surfaces 151a, 151b may define a radius R. As shown in the drawing, the fins 190a and 190b extend in the Y-axis direction further than the base end portions 153a and 153b of the wall portions 150a and 150b, respectively, or than the vertical plane defined by the base end portions 153a and 153b of the wall portions 150a and 150b, respectively, thereby facilitating engagement of the fins 190a and 190b with the opening 980 defined in the base 900.
Fig. 20C is a top view of the clip 100 of fig. 20A. As shown, the centers 192a, 192b of the fins 190a, 190b and the centers of the gussets 180a, 180b are offset from the transverse centerline 102 by an offset distance 196, which may facilitate the manufacture of the clip 100 by injection molding or the like.
Fig. 20D is a bottom view of the clip 100 of fig. 20A. As shown, the center of each gusset 180c, d may be offset from the transverse centerline 102 by an offset distance such as the offset distance 196 described above, which, as discussed above, may facilitate the manufacture of the clip 100 by injection molding or the like. To facilitate release of the clip 100 from the hook 600 (shown in fig. 6) by a removal tool 1200 or the like (shown in fig. 21A), a length L of the notch 380 in the X-axis direction, or a direction parallel to the orientation of the gap 168 defined between the first latch hook 160a and the second latch hook 160b, is greater than a width W of the notch 380 in the Y-axis direction, or a direction orthogonal to the length L. As shown, the indentation 380 may be a slot aperture and may define an oblong shape.
Fig. 21A to 21D show a removal tool 1200 according to another embodiment of the present disclosure. As shown in fig. 21A, which is a top perspective view of the removal tool 1200, a shaft 1220 forming a tapered first portion 1510 extends from the handle 1210, and a linear second portion 1520 defining a tip 1310 extends from the first portion 1510. As shown in fig. 21B, which is a detailed top view of the shaft 1220 of the removal tool 1200, the shaft 1220 can define a shoulder 2110 at an intersection or the like between the first portion 1510 (illustrated in fig. 21A) and the second portion 1520 (illustrated in fig. 21A). The top end 1310 defines a conical shape at the edge treatments 2150a, 2150b that may have a curvature, or may be chamfered. Fig. 21C is a side view of the removal tool 1200 of fig. 21B. As shown, the center of the shaft 1220 of the removal tool 1200 may be offset from the center of the handle 1210 by an offset distance 2170. For example and without limitation, such biasing may provide improved ergonomics for a user of the removal tool 1200. Fig. 21D is an end view of the removal tool 1200 of fig. 21B.
Fig. 22A-22C illustrate an installation tool 2200 for assembling the assembly 1000 of fig. 11, and more particularly, with or without a cover 1010 (shown in fig. 10) therebetween, for installing a hanger 600 (shown in fig. 6) to a clip 100 (shown in fig. 20A). As shown in fig. 22A, which is a top perspective view of the installation tool 2200, the installation tool 2200 may include a handle 2210 and a shaft 2220 extending from the handle 2210 in the Z-axis direction. The shaft 2220 may include a first portion 2211 defining a side surface, and a second portion 2212 defining a side surface, a top surface 2221, and a top end 2250. The tip 2250 of the shaft 2220 may include first and second side portions 2213a, 2213B, 2214a, 2214B that may define a forked tip 2250, the forked tip 2250 defining a clip cavity 2216 (illustrated in fig. 22B) and a hook cavity 2218 (illustrated in fig. 22C) therebetween sized to accommodate the clip 100 and the hook 600, respectively. In several ways, the centerline axis 2201 of the handle 2210, the side portions 2213a, 2214a and the side portions 2213b, 2214b of the second portion 2212 may coincide with the X-axis direction of the clip 100 when the clip 100 is installed. In several ways, the tip 2250 of the shaft 2220 may define at least one of a clip cavity 2216, specifically sized to receive the upper end of the clip 100, and a hook cavity 2218, specifically sized to receive the upper end of the hook 600. For example and without limitation, the upper end of clip 100 and hook 600 may be defined by top end 2250 of clip 100 and flange 620 of hook 600, respectively.
Fig. 22B is a side view of the installation tool 2200 of fig. 22A. The first side portion 2213a, 2213B (2213B is illustrated in fig. 22A) and the second side portion 2214a, 2214B (2214B is illustrated in fig. 22A) are saddle-shaped, and the clip cavity 2216 is capable of receiving the end portions 154a, 154B (illustrated in fig. 20B) of the wall portions 150a, 150B (illustrated in fig. 20B) of the clip 100 (illustrated in fig. 20B) during installation of the hook 600 (illustrated in fig. 6) to the clip 100. The top surface 2221 may be recessed or offset a sufficient distance relative to the top end 2250 of the shaft 2220 to ensure that when the top surface 2221 abuts (with or without the cover 1010 therebetween) the distal ends 154 of the wall portions 150a, 150b of the clip 100 from the bottom, the hook 600 is fully inserted into the clip 100 and snapped into locking engagement with the clip 100. At the same time, the top surface 2221 may be recessed or offset a sufficiently short distance relative to the top end 2250 of the shaft 2220 so that the hook 600 is not pressed too far into the clip 100 when the top surface 2221 abuts the tip portions 154 of the wall portions 150a, 150b of the clip 100 from the bottom (again with or without the cover 1010 therebetween).
Fig. 22C is an end view of the installation tool 2200 of fig. 22A. As shown, the shaft 2220 of the installation tool 2200 may define an X-axis direction shaft thickness 2270 that may be constant up and down over at least a portion of the shaft 2220. The hook chamber 2218 can define a width 2290a proximate the top surface 2221 and a width 2290b proximate the top end 2250. As shown, width 2290b is greater than width 2290a, corresponding to the size and shape of hook 600 (shown in FIG. 6) with or without cover 1010 (shown in FIG. 10). The first and second side portions 2213a, 2213b, 2214a, 2214b (illustrated in fig. 22A) may taper towards the tip 2250 and may be capable of defining an edge treatment.
Fig. 23 is a bottom view of the assembly 1000 showing a plurality of clips 100 positioned on the bottom surface 911 of the base 900. In various ways, any number of clips 100 may be mounted to base 900 to secure cover 1010. In several ways, a certain number of clips 100 may be specified. In other ways, the spacing 1600 of adjacent clips 100 may be specified. If the interval 1600 between many clips 100 and the adjacent clip 100 is short, in some way, a substantially good appearance can be obtained. For example and without limitation, the spacing of the clips 100 is set to a minimum of about 5 millimeters, or at least the entire width of the clips 100 in the X-axis direction, typically about 100 millimeters, although the possibility exists of using any spacing that is physically possible. Each clip 100 of the plurality of clips 100 extends through one of the plurality of openings 980 (shown in fig. 9), and each of the plurality of clips 100 can be assembled to a hook 600 (shown in fig. 6).
In combination with the features disclosed herein, including, for example and without limitation, more than one radius as shown (which may also improve insertion of the clip 100 into the substrate 900), the overall weight of the clip 100 may also be reduced by more than 75%. As described above, the base 110 is illustrated as a base comprising one of a variety of sizes and shapes, but the base 110 may be defined to be any size and shape. As shown in the drawing, by introducing various radii to one or more edge portions of the clip 100, the weight of the clip 100 can be further reduced.
The clip 100 may be made of any of several deformable materials capable of elastically deforming to the extent described, including but not limited to modified polymers such as Polyoxymethylene (POM), which is one type of acetal resin. The clip is formed by an injection molding process, such as, without limitation, an extrusion process and/or a machining process, among other processes, are also contemplated. The base 900 itself can be made of a desired material using a variety of processes, is not itself dependent on the material of the base 900, but can provide a separate fastening function, which is an important advantage of the clip 100.
The assembly method can include obtaining a base 900 (shown in fig. 9), the base 900 can define a bottom surface 911 (shown in fig. 9) and a top surface 912 (shown in fig. 9) and a plurality of openings 980 (shown in fig. 9) extending from the bottom surface 911 to the top surface 912. The method may include the step of inserting the clip 100 into one of the plurality of openings 980. The gap 168 (illustrated in fig. 1) defined by the first and second latch hooks 160a, 160b of the clip 100 may be configured to expand to a degree sufficient to enable removal of the hook 600 (illustrated in fig. 6) upon insertion of a removal tool 1200 (illustrated in, for example, fig. 12) between the first and second wall portions 150a, 150 b. The method can include the step of inserting the hook 600 into the gap 168 of the clip 100. The step of inserting the hanger 600 may include pressing the hanger 600 into the gap 168 of the clip 100 using an installation tool 2200, which installation tool 2200 may include a shaft 2220. More specifically, the insertion of the hook 600 into the gap 168 of the clip 100 may include, among other ways: the hook 600 is pressed into the gap 168 in a state where a panel or a part of the cover 1010 is folded so as not to be an obstacle and a part of the hook 600 such as the flange 620 (shown in fig. 6) or the band 670 (shown in fig. 6) is in contact with the attachment tool 2200. In this manner, the user can guide the attachment tool 2200 into the engaging contact state with the hook 600 at a position close to or aligned with the clip 100. In other ways, insertion of hook 600 into gap 168 of clip 100 may include the following: in a state where cover 1010 is disposed between hook 600 and attachment tool 2200, hook 600 is pressed into gap 168.
The method may further comprise the step of expanding the first wall portion 150a and the second wall portion 150b such that the gap 168 between the first wall portion 150a and the second wall portion 150b is increased. The method may further comprise the step of removing the hanger 600 from the clip 100 without permanently deforming (i.e., permanently changing the basic shape of) either the clip 100 or the hanger 600. The step of expanding the first and second wall portions 150a, 150b may include inserting a removal tool 1200 from a notch 380 defined in the base 110 of the clip 100 toward an expansion chamber 290 defined between the first and second wall portions 150a, 150b of the clip 100. The step of removing hook 600 may include contacting a removal tool 1200, which may define a tapered portion, with hook 600.
