Description

[0001] Citation of relevant applications

[0002] This application claims the benefit of U.S. Provisional Patent Application No. 63 / 145,087, filed February 3, 2021, entitled “SLIDE FASTENER SEALING SYSTEMSAND METHODS”, the contents of which are hereby incorporated by reference in their entirety. Technical Field

[0003] This application relates to a sliding fastener sealing system and related methods, which can be used in applications involving liquids or potentially harmful gases. Background Technology

[0004] Zippers and other sliding fasteners can be used to secure components in applications involving liquids and / or potentially hazardous gases. As some non-limiting examples, zippers and other sliding fasteners can be used as needed in waterproof clothing, lab coats, boat covers, and other applications. As a non-limiting example, zippers and other sliding fasteners can be used to removably fasten components of waterproof clothing, allowing the user to put on and take off the clothing relatively easily. In applications involving liquids and / or potentially hazardous gases, the sliding fasteners should ideally not impair the article's (e.g., waterproof clothing) ability to resist or minimize the entry or exit of fluids and / or gases. While some sealing zippers and zipper systems exist on the market for this purpose, all available options have drawbacks, and there is still room for improvement. This patent describes an improved sliding fastener sealing system and related methods. Summary of the Invention

[0051] The following describes several examples of sliding fastener sealing systems and related methods. The discussion will begin with... Figure 1-11 The example shown is shown in the image.

[0052] Structure and Relationships of Parts

[0053] Reference Figure 10 , Figure 1-11 The sealing zipper assembly includes a first zipper segment 12 and a second zipper segment 14, which overlap to create a sealing area 16. (Refer to...) Figure 6 and Figure 9 The sealed area 16 can be considered as forming a tunnel. (See reference...) Figure 10 In this respect, the sealing area 16 has an external opening 18 and an internal opening 20. (See reference...) Figure 9 and Figure 10 The sealing element 22 is positioned within the sealing area 16 to prevent leakage between the first zipper segment 12 and the second zipper segment 14. (Refer to...) Figure 11 The sealing element 22 is shown. (See reference...) Figure 9 and Figure 10 The sealing element 22 is elastically deformable and compressed within the sealing area 16 by the first zipper segment 12 and the second zipper segment 14. (Refer to...) Figure 10 It will be noted that, with respect to this first example, the first zipper segment 12 and the second zipper segment 14 are portions of a single interlocking zipper fastener 24 and create a single sealing area (which is previously identified as sealing area 16). As will be shown and described below with reference to other examples, there may be more than one interlocking zipper fastener and more than one sealing area.

[0054] Reference Figures 1 to 5 and Figure 8 The interlocking zipper fastener 24 has a first series of interlocking teeth 26 supported on the belt 28 and a second series of interlocking teeth 30 supported on the belt 32. At least one slider 34 is provided. (See reference...) Figure 7 and Figure 10 In this embodiment, the interlocking zipper fastener 24 has a first end 36 serving as a first zipper segment 12 and a second end 38 serving as a second zipper segment 14.

[0055] Reference Figure 2 The garment body 40, made of waterproof fabric, comprises a first or upper separate body member 42 and a second or lower separate body member 44. An interlocking zipper fastener 24 has a circular construction, allowing the first separate body member 42 to be separated from the second separate body member 44. (See reference...) Figure 2 The belt 28 (which supports a first series of interlocking teeth 26 forming the first half of the interlocking zipper fastener 24) is generally circularly mounted to the first separate body member 42 to form the first half of the first zipper segment 12 and the first half of the second zipper segment 14 in an overlapping relationship. Similarly, the belt 32 (which supports a second series of interlocking teeth 30 forming the second half of the interlocking zipper fastener 24) is generally circularly mounted to the second separate body member 44 to form the second half of the first zipper segment 12 and the second half of the second zipper segment 14 in an overlapping relationship.

[0056] Reference Figure 3 The slider 34 is used to slide along the interlocking zipper fastener 24 in a first direction to engage the first series of interlocking teeth 26 and the second series of interlocking teeth 30, such as... Figure 1 As shown in the image. (Refer to...) Figure 4 The sliding member 34 slides along the interlocking zipper fastener 24 in the second direction to disengage the first series of interlocking teeth 26 and the second series of interlocking teeth 30, thereby disengaging the interlocking zipper fastener 24. Figure 2 As shown in the image. (Refer to...) Figure 6 , Figure 7 , Figure 9 and Figure 10 When the slider 34 interlocks the first series of interlocking teeth 26 and the second series of interlocking teeth 30, the slider 34 completes the first zipper segment 12 and the second zipper segment 14, their overlap creating a sealing area 16. The sealing area 16 is then ready to receive the sealing element 22. (Refer to...) Figure 11 The sealing element 22 has ridges 46 that aid in sealing. The sealing element 22 also has a first channel 48 on the first surface 50 and a second channel 52 on the second surface 54. (See reference...) Figure 9 The first channel 48 receives the interlocking teeth 56 of the first zipper segment 12, and the second channel 52 receives the interlocking teeth 58 of the second zipper segment 14.

[0057] operate

[0058] Reference Figure 2 A belt 28 (which supports a first series of interlocking teeth 26 forming the first half of the interlocking zipper fastener 24) is generally circularly mounted to the first separate body member 42 to form the first half of the first zipper segment 12 and the first half of the second zipper segment 14 in an overlapping relationship. A belt 32 (which supports a second series of interlocking teeth 30 forming the second half of the interlocking zipper fastener 24) is generally circularly mounted to the second separate body member 44 to form the second half of the first zipper segment 12 and the second half of the second zipper segment 14 in an overlapping relationship. See reference. Figure 3 The sliding member 34 slides along the interlocking zipper fastener 24 in a first direction to engage the first series of interlocking teeth 26 and the second series of interlocking teeth 30, as shown. Figure 1 As shown in the image. (Refer to...) Figure 6 and Figure 7 When the slider 34 interlocks the first series of interlocking teeth 26 and the second series of interlocking teeth 30, the slider 34 completes the first zipper segment 12 and the second zipper segment 14, and their overlap creates a sealing area 16. (Refer to...) Figure 9 and Figure 10The sealing element 22 is compressed within the sealing area 16 by the first zipper segment 12 and the second zipper segment 14.

[0059] Variant

[0060] Several variations that can be made to the first instance described above will be described below.

[0061] The first example includes a single sealing element 22. (See reference...) Figure 15 The image shows an alternative sealing element 122, which has a first sealing member 124 and a second sealing member 126. (See reference...) Figure 12 The first sealing member 124 is wedged into the first discrete body member 42 and is held in place by friction or otherwise secured to the first discrete body member 42. The second sealing member 126 is wedged into the second discrete body member 44 and is held in place by friction or otherwise secured to the second discrete body member 44. (See reference...) Figure 13 and Figure 14 When the interlocking zipper fastener 24 is closed, the first sealing member 124 and the second sealing member 126 are forced together to form a sealing element 122 that fills the sealing area 16.

[0062] In the first example discussed above, the sealing element 22 is held in place by friction and is removable. (See reference...) Figure 16 and Figure 17 The alternative sealing element 222 has a fabric strip 224 molded into an elastic foam. The fabric strip 224 is used to secure the alternative sealing element 222 to the first discrete body member 42. This is accomplished by sewing through the fabric strip 224. The fabric strip 224 is used to anchor the alternative sealing element 222 to the first discrete body member 42 at a desired location, where the sealing area 16 is formed by the overlap of the first zipper segment 12 and the second zipper segment 14 of the interlocking zipper fastener 24. It will be appreciated that other methods exist for securing the alternative sealing element within the sealing area 16.

[0063] In the first example discussed above, the sealing element 22 is elastic foam. (Refer to...) Figure 18 and Figure 19 The alternative sealing element 322 is shown. (See reference...) Figure 18 The sealing element 322 is a plug 324, which is suspended from the slider 34 by a cord 326 when not in use. (See reference...) Figure 19 The plug 324 is intended to be inserted into the external opening 18 of the sealing region 16 to seal the sealing region 16. Preferably, the plug 324 has surface profiles (such as ribs or ridges) to enhance both the sealing and retention capabilities of the plug 324. It will be appreciated that other raised surface profiles exist that will similarly serve this purpose.

[0064] In the first example described above, the first zipper segment 12 and the second zipper segment 14 are positioned substantially parallel to the interlocking zipper fastener 24. (Refer to...) Figure 22 The first zipper segment 12 and the second zipper segment 14 forming the sealing area 16 may be configured to protrude outward or radially from the interlocking zipper fastener 24.

[0065] In the first example discussed above, there is only one interlocking zipper fastener 24 and only one sealing area 16. (Refer to...) Figure 23 The diagram illustrates a configuration having more than one interlocking zipper fastener 24 and more than one sealing region 16. In this configuration, a first end 36 of one interlocking zipper fastener 24 serves as a first zipper segment 12, and a second end 38 of another interlocking zipper fastener 124 serves as a second zipper segment 14 to create the first sealing region 16. Additionally, the first end 36 of the interlocking zipper fastener 124 serves as the first zipper segment 12, and the second end 38 of the interlocking zipper fastener 24 serves as the second zipper segment 14 to create a second sealing region 116. It will be appreciated that although the two interlocking zipper fasteners 24 and 124 are shown in a circular configuration, more than two interlocking zipper fasteners can also be arranged in a similar circular configuration.

[0066] Not uncommon is that garments designed for use in water (such as garment body 40) have air delivery valves to provide air movement. (See reference...) Figure 24 The diagram shows an alternative sealing element 422, wherein an air delivery conduit 424 extends through the body of the alternative sealing element 422. The air delivery conduit 424 allows air to move in and out of the garment body 40. A shut-off valve 426 can be used to close the air delivery conduit 424 when the garment body 40 is to be immersed in water or another liquid.

[0067] In the first example discussed above, sealing element 22 is compressed. (Refer to...) Figure 25 This illustrates a sac-shaped alternative sealing element 522 that can inflate like a balloon. The alternative sealing element 522 has a tube 524 and a shut-off valve 526. A user can blow air into the tube 524 to inflate the alternative sealing element 522, and the shut-off valve 526 maintains the air pressure within the alternative sealing element 522. When inflated, the alternative sealing element 522 expands to occupy the sealing area 16.

[0068] Another alternative sealing element is positioned between two clamping elements, wherein at least one of the clamping elements is movable toward and away from the other. As the clamping elements move closer together, the sealing element is forced outward to seal the sealing area. (See reference...) Figure 26The diagram illustrates one such clamping configuration. The alternative sealing element 622 has a bolt 624 extending longitudinally through it. A nut 626 is present at one end of the bolt 624, and a torsion knob 628 is present at the other end. The nut 626 serves as one clamping element, and the torsion knob 626 serves as another. Rotating the torsion knob 628 causes axial movement that compresses the alternative sealing element 622 between the torsion knob 628 and the nut 626. When compressed, the alternative sealing element 622 expands outward, increasing its circumference until it seals the sealing area.

[0069] Warning

[0070] It will be recognized that not all zippers work in liquid environments. To prevent leaks, waterproof zippers are desirable. It will also be recognized that many different types of waterproof zippers exist.

[0071] In order for the sealing elements described above to be effective, it may be desirable to take additional precautions to address potential leak points along seams and joints.

[0072] Reference Figure 1 The stitch 50 is used to secure the interlocking zipper fastener 24 in place. (Refer to...) Figure 5 The waterproof tape 52 is heat-sealed or secured to the reverse side of the seam 50 by adhesive to prevent liquid leakage through the seam 50.

[0073] Reference Figure 20 and Figure 21 The sealing area 16 has an edge joint 54 that is resistant to leakage. (See reference...) Figure 20 Leakage can be resolved by using a flexible edge molding 56 to seal the edge joint 54. (See reference...) Figure 21 Leakage can also be addressed by sealing the edge joints 54 with beads 58 of a polymer sealant compound.

[0074] Improved sliding fastener sealing system

[0075] Figures 27 to 41 Another example of a sliding fastener sealing system 1000 is shown, which is characterized by improvements, modifications and replacements to the sliding fastener sealing system described above. Figure 27 The system 1000 shown includes a sliding fastener 1002 and a sealing component 1004. The sliding fastener sealing system 1000 can be incorporated into multi-piece waterproof clothing or other multi-piece sealing systems to allow the components of these systems to be removably fastened together while still providing a seal to prevent fluid leakage through the sliding fastener sealing system.

[0076] Sliding fasteners

[0077] Figure 28 and Figure 29 Show in more detail Figure 27 The sliding fastener 1002, wherein Figure 29 A cross-section of the sliding fastener is shown. The sliding fastener 1002 includes two strips 1006, each strip having a series of fastening elements 1008 positioned along the strip. Although in Figure 28 and Figure 29 Not shown, but the sliding fastener 1002 may include a slider (similar to, for example...) Figure 1 The slider 34 shown is configured to engage and disengage the fastening elements 1008 of the two straps 1006 when sliding along the sliding fastener 1002.

[0078] like Figure 28 As shown in the figure, one end of the two straps 1006 overlaps with the other end of the two straps 1006 (the overlap and adjacent lengths of the sliding fasteners are shown only in these figures). Figure 28 and Figure 29 The sliding fastener 1002 can be in the form of a ring (similar to) Figure 7 The ring shown in the image is formed. Although Figure 7 The illustration shows a sliding fastener formed by a circular ring, but other ring shapes and constructions are also possible. Figure 28 and Figure 29 As shown, the overlapping ends of each strip 1006 are secured together along their edges 1010. This can be accomplished by heat-sealing the edges of the strip ends together or by other means. Figure 29 As shown, the sliding fastener 1002 includes a side seal 1012 inside (discussed later below), wherein the overlapping ends of the strap 1006 are joined together.

[0079] The sliding fastener shown in this example is a separable sliding fastener, in which the two straps 1006 can be completely detached from each other and reattached during normal use. Figure 28 and Figure 29 As shown, the detachable sliding fastener includes a retaining box 1014 at the end of a series of fastening elements 1008 of one of the straps 1006, and an insertion pin 1016 at the end of a series of fastening elements 1008 of the other strap 1006. The insertion pin 1016 can be inserted into the retaining box 1014, and a slider slides along the fastening elements 1008 to fasten the two straps 1006 together. The slider can slide in the opposite direction, and the insertion pin 1016 can be removed from the retaining box 1014 to separate the two straps 1006 from each other.

[0080] like Figure 29 As shown, when the sliding fastener 1002 is looped (where one end of the strap 1006 overlaps the other end, and the edges 1010 of the strap 1006 are secured together), a passage 1018 is formed between the overlapping ends. When the sliding fastener 1002 is incorporated into waterproof clothing or other sealing systems, the passage 1018 is a place where water, another liquid, or gas can seep into or out of the system via the open end of the passage 1018, where the strap 1006 no longer overlaps. As discussed further below, the passage 1018 defines a sealing area for receiving the sealing element 1004 to resist fluid penetration through the passage 1018.

[0081] sealing components

[0082] Figures 30-37 An example of a sealing member 1004 is shown, which can be inserted into a passage 1018 of a sliding fastener 1002 to resist fluid penetration through the passage 1018. In this particular example, the sealing member 1004 includes three components: a connector 1020, a sealing body 1022, and a sealing body actuator 1024.

[0083] Connector component 1020 in Figure 34 and Figure 35 The portion shown is unrelated to the rest of the sealing component assembly 1004. Connector 1020 is configured to connect the sealing component 1004 to the sliding fastener 1002. Figures 34-35 In the particular example shown, connector 1020 includes a spring hook 1026 that hooks around the end 1005 of the strap of sliding fastener 1002. Figure 35 As shown, the spring hook 1026 includes an inclined surface 1028, a recess 1030, and a protrusion 1032, which engage and receive the retaining box 1014 and the insertion pin 1016 of the sliding fastener 1002 to secure the sealing member 1004 in place at the end of the sliding fastener strip 1006. The connector 1020 also includes an aperture 1034 for slidably receiving the sealing body actuator 1024, as discussed in further detail below.

[0084] Figure 34 and Figure 35The connector 1020 shown includes an arm 1036 that connects and anchors the connector 1020 to a sealing body 1022, which can be molded onto the connector 1020 during manufacturing. The sealing body 1022 can be formed of a soft, deformable material. The sealing body 1022 can have a basic shape in which the sealing body 1022 does not deform. As discussed in more detail below, the sealing body 1022 can be selectively deformed and expanded from its basic shape using a sealing body actuator 1024. Figure 36 In this context, the sealing body 1022 is shown as being independent of the rest of the sealing component assembly 1004. The sealing body 1022 has an outer sidewall 1038, which is shaped or otherwise configured to conform to the shape of the side seal 1012 of the sliding fastener 1002 (see, for example, further discussed below). Figures 40-41 The sealing body includes grooved top and bottom surfaces 1040 configured to receive and conform to the fastening element 1008 of the sliding fastener 1002, and also provides a gap through which the slider can move. Like connector 1020, sealing body 1022 includes an aperture 1042 for slidably receiving sealing body actuator 1024.

[0085] Sealed body actuator 1024 in Figure 37 The diagram shows that it is not related to the rest of the sealing component 1004. For example... Figure 37 As shown, the sealing body actuator 1024 tapers between a thicker end 1044 and a narrower end 1046. As the thicker end 1044 moves further into the sealing body 1022, the deformable sealing body 1022 expands from its basic shape to accommodate the thicker end 1044. Conversely, as the narrower end 1046 moves further into the sealing body 1022, the deformable sealing body 1022 contracts back towards its basic shape. It will be appreciated that when the narrower end 1046 is in the sealing body 1022, the deformable sealing body 1022 may not completely return to its basic shape. Figure 37 The sealing body actuator 1024 shown can be connected to the handle toward the narrower end 1046, such as Figure 18 The tether 325 is shown. A handle can be used to pull the thicker end 1044 of the sealing body actuator 1024 into the sealing body 1022, causing the sealing body 1022 to deform and expand. (See attached image.) Figure 37 As shown, the sealing body actuator 1024 includes an orifice 1048 to which a handle can be attached. Also, Figure 37As shown, the sealing body actuator 1024 includes a handle 1050 at its thicker end 1044, which can be used to pull the thicker end 1044 of the sealing body actuator 1024 from the sealing body 1022, causing the sealing body 1022 to retract. The narrower end 1046 of the actuator may also extend beyond the end of the sealing body 1022, allowing the actuator 1024 to be pushed to move the narrower end 1046 of the actuator 1024 into the sealing body 1022, causing the sealing body 1022 to retract.

[0086] Although not specifically shown in the figures, the sealing body actuator 1024 and / or the handle connected to the actuator 1024 may be long enough to extend beyond the end of the passage 1018 formed by the overlapping ends of the sliding fastener 1002, and / or be accessible from the outside of the garment or other waterproof structure in which the sliding fastener sealing system 1000 is used.

[0087] How to use

[0088] Figures 27 to 41 The sliding fastener sealing system 1000 can be used by: attaching a sealing member 1004 to the end of a sliding fastener 1002; sliding the slider of the sliding fastener to engage the fastening element 1008 and close the sliding fastener 1002 over the top of the sealing member 1004; and actuating a sealing body actuator 1024 to deform the sealing body 1022, causing it to expand. Actuating the sealing body actuator 1024 allows the sealing body 1022 to conform to the interior of the side seal 1012 and the band 1006, thereby sealing the passage 1018 to prevent fluid penetration through it. Actuating the sealing body actuator 1024 also allows the sealing body 1022 to conform to the element of the sliding fastener, which forms a seal with respect to the element of the sliding fastener to prevent fluid penetration through it.

[0089] Figure 38-41A sealing member 1004 is shown, which is mounted in a passage 1018 of a sliding fastener 1002 such that the sealing body 1022 of the sealing member 1004 is adjacent to the side seal 1012 of the sliding fastener 1002 in the sealing region of the passage 1018. Both the sealing body 1022 and the side seal 1012 are made of a relatively soft and compliant material to facilitate the formation of a fluid-impermeable seal that blocks the interior of the passage 1018. In one example, the sealing body 1022 comprises a material having a Shore hardness in the range of 0030 to Shore D65 and including 0030 to Shore D65, such as a hardness in the range of Shore A0 to Shore A30, such as a hardness in the range of Shore A0 to Shore A10 and including Shore A0 to Shore A10. In a non-limiting example, the sealing body 1022 may comprise a Shore A2 elastic material. In one example, the side seal 1012 comprises a material having a Shore hardness in the range of 0030 to Shore D65, including, for example, a Shore A30 to Shore A90, or in some examples, a Shore A50 to Shore A70. The side seal may comprise a Shore A60 polyurethane material. Shore hardness can be measured, for example, using a hardness tester and by following the test procedures set forth in ASTM D2240.

[0090] performance

[0091] Figures 27 to 41 The sliding fastener sealing system 1000 is relatively impermeable to penetration by fluids (including liquids and / or gases). The sliding fastener 1002 itself can be a waterproof zipper, such as, for example... Zipper. As described above, sealing member 1004 can be used to resist the penetration of fluid through passage 1018 between overlapping ends of sliding fastener 1002, which are fastened together to form a passage.

[0092] For example, the sliding fastener sealing system 1000 can resist fluid penetration for up to 20 seconds at a pressure of at least 1 PSI. In another example, the sliding fastener sealing system 1000 can resist fluid penetration for up to 20 seconds at a pressure of at least 4 PSI. In another example, the sliding fastener sealing system 1000 can resist fluid penetration for up to 20 seconds at a pressure of at least 6.5 PSI. In yet another example, the sliding fastener sealing system 1000 can resist fluid penetration for up to 20 seconds at a pressure between 1 PSI and 6.5 PSI. In these examples, the sliding fastener sealing system 1000 resists fluid penetration through the sliding fastener 1002 itself and through the passage 1018, in which the sealing element 1004 is positioned.

[0093] Hydrostatic pressure testing methods can be used to measure resistance to fluid penetration, such as the hydrostatic pressure testing method described in Section 7.9 of the AA-55634C product description for zippers (fasteners, slip interlocks) authorized by the General Services Administration of the United States Federal Government (October 30, 2019 version).

[0094] Figure 42 An example of a hydrostatic pressure testing method is illustrated schematically. It should be noted that... Figure 42 A typical zipper sample is shown, but a sliding fastener sealing system including a sliding fastener and a sealing component is not specifically shown. This is for testing purposes. Figure 27 The sliding fastener sealing system shown in the figure, such as Figure 27 The sample of a certain length shown can be installed Figure 42 In the testing apparatus, the sliding fastener is in a closed configuration, the sealing element is positioned in a passage formed by the overlapping ends of the sliding fastener, and the sealing body is in an expanded configuration within the passage. To perform the test, the sample is mounted in the testing apparatus such that it is sealed with gaskets at all its edges, then immersed in water (e.g., the entire sample is covered to a depth of approximately 1 inch), and then subjected to air pressure for a certain period of time while observing the top of the sample for air leakage (e.g., air bubbles).

[0095] The sealing elements described herein can be made of a variety of materials suitable for selectively forming a seal with another component, and the sealing elements are not limited to elastic foam. As some non-limiting examples, in other embodiments, the sealing elements can be, as needed, a variety of elastic deformable materials, thermoplastic elastomers, combinations thereof, or other various materials.

[0096] While the sliding fastener sealing systems described herein are discussed in the context of waterproof clothing, they are by no means so limiting. Instead, sliding fastener sealing systems can be used as needed in other applications involving liquids and / or potentially hazardous gases (including, but not limited to, boat covers, lab coats, bags, cases, and other applications). Furthermore, sliding fastener sealing systems can be used in other applications that do not necessarily involve liquids and / or potentially hazardous gases.
