SNAP FASTENER WITH HOOK

TECHNICAL FIELD
Field of Use

This disclosure relates to snap fasteners. More specifically, this disclosure relates to snap fasteners with hooks that can be used to removably hang objects, e.g., privacy curtains in a health care setting.

Related Art

Privacy curtains or “cubicle curtains” can be used to divide areas and/or provide privacy, especially in healthcare facilities such as, for example and without limitation, hospitals, clinics, or nursing homes. Fire codes can require that an upper section of each privacy curtain to be made of or comprise a mesh material, called the “top mesh.” During a fire, the top mesh can allow passage of water from sprinkler heads, usually mounted on a ceiling, to any part of the room without the curtain being a significant obstacle. A privacy curtain, including when incorporating such mesh material, can also allow for more light into the patient treatment area and can also allow for better air flow through the area. A lower section of the curtains can comprise an opaque or solid material.

The privacy curtain and, more specifically, at least the upper section thereof can be manually hung on carriers, which typically slide through or along a channel or track that is permanently attached to a ceiling. In hospital and other patient-care facilities, the ceilings can be eight to nine feet from floor to ceiling. A facility's personnel cannot easily reach such heights without using a ladder or power lift—not only during initial installation of the carriers and the curtains but also during regular removal of the curtains for cleaning and/or repair. Even where personnel can remove and reattach the lower section from the upper section where for example the lower section is secured to the upper section with fasteners (e.g., snap fasteners), such removal and reattachment can require two hands and the breaking or reengagement of a mechanical joint and can require the user to somehow, directly or indirectly, access both sides of the curtain, which can itself be difficult.

More generally, separate removably engageable components of a multi-piece fastener such as a snap fastener are typically configured for engagement with each other—in the process, typically joining two structural components to each other (e.g., two pieces of fabric in a clothing garment or a vehicle cover to a boat), but the fastener itself typically does not include functionality beyond such engagement of such components with each other.

DETAILED DESCRIPTION

The present disclosure can be understood more readily by reference to the following detailed description, examples, drawings, and claims, and their previous and following description. However, before the present devices, systems, and/or methods are disclosed and described, it is to be understood that this disclosure is not limited to the specific devices, systems, and/or methods disclosed unless otherwise specified, as such can, of course, vary. It is also to be understood that the terminology used herein is for the purpose of describing particular aspects only and is not intended to be limiting.

The following description is provided as an enabling teaching of the present devices, systems, and/or methods in their best, currently known aspect. To this end, those skilled in the relevant art will recognize and appreciate that many changes can be made to the various aspects described herein while still obtaining the beneficial results of the present disclosure. It will also be apparent that some of the desired benefits of the present disclosure can be obtained by selecting some of the features of the present disclosure without utilizing other features. Accordingly, those who work in the art will 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. Thus, the following description is provided as illustrative of the principles of the present disclosure and not in limitation thereof.

As used throughout, the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to a quantity of one of a particular element can comprise two or more such elements unless the context indicates otherwise. In addition, any of the elements described herein can be a first such element, a second such element, and so forth (e.g., a first widget and a second widget, even if only a “widget” is referenced).

Ranges can be expressed herein as from “about” one particular value and/or to “about” another particular value. When such a range is expressed, another aspect comprises 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 both in relation to the other endpoint and independently of the other endpoint.

For purposes of the current disclosure, a material property or dimension measuring about X or substantially X on a particular measurement scale measures within a range between X plus an industry-standard upper tolerance for the specified measurement and X minus an industry-standard lower tolerance for the specified measurement. Because tolerances can vary between different materials, processes, and between different models, the tolerance for a particular measurement of a particular component can fall within a range of tolerances.

As used herein, the terms “optional” or “optionally” mean that the subsequently described event or circumstance may or may not occur, and that the description comprises instances where said event or circumstance occurs and instances where it does not.

The word “or” as used herein means any one member of a particular list and also comprises any combination of members of that list. The phrase “at least one of A and B” as used herein means “only A, only B, or both A and B”; while the phrase “one of A and B” means “A or B.”

As used herein, unless the context clearly dictates otherwise, the term “monolithic” in the description of a component means that the component is formed as a singular component that constitutes a single material without joints or seams. Unless otherwise specified herein, any structure disclosed in the drawings or in the written description as being so formed can be monolithic whether or not such an explicit description of the structure is included herein.

To simplify the description of various elements disclosed herein, the conventions of “left,” “right,” “front,” “rear,” “top,” “bottom,” “upper,” “lower,” “inside,” “outside,” “inboard,” “outboard,” “horizontal,” and/or “vertical” may be referenced. Unless stated otherwise, “front” describes that side of the curtain and that end of the fastener nearest to and occupied by a snap member of the fastener and, more specifically, a second engagement portion (e.g., a hook portion) of the snap member; “rear” is that side of the curtain and end of the fastener that is opposite or distal the front; “left” is that which is to the left of or facing left from a person facing towards the front; and “right” is that which is to the right of or facing right from that same person facing towards the front. “Horizontal” or “horizontal orientation” describes that which is in a plane extending from left to right and aligned with the horizon. “Vertical” or “vertical orientation” describes that which is in a plane that is angled at 90 degrees to the horizontal.

The fastener can also be described using a coordinate axis of X-Y-Z directions shown in FIG. 2. An X-axis direction can be referred to as a left-right or horizontal direction. An upper-lower direction is a Z-axis direction orthogonal to the X-axis direction and to a Y-axis direction. The Y-axis direction is orthogonal to the X-axis direction (left-right direction) and the Z-axis direction (upper-lower direction) and can also be referred to as a front-rear direction. A surface of a structural element that is parallel with the front-rear direction can be referred to as a lateral side.

In one aspect, a first portion or snap member and associated methods, systems, devices, and various apparatuses are disclosed herein. In one aspect, the snap member can comprise a second engagement portion or hook portion.

The aforementioned curtains can be any suitable width and any suitable length. Because the curtains can in some cases be long enough or tall enough to extend from a floor to a ceiling of a room (e.g., as much as 96″ long or longer in finished length) and can be wide enough to extend across the room or circumscribe an area, the curtain can be heavy and bulky to move and hang, even if split into multiple pieces. When the curtain is split into an upper section and a lower section, a point of connection between the upper section and the lower section can be seven to eight feet off the ground or floor.

Cleaning of the curtain can be done as often as weekly or whenever a patient is discharged from an area enclosed by the curtain. Facility standards and/or patient needs can require that if any portion of the curtain is stained, especially with human or chemical fluids, it must be removed and cleaned, which is usually if not always done in a separate location. Facility standards and/or patient needs can require that, in such case, a replacement curtain be hung when the original curtain is removed. The cleaning itself can be and usually is performed using industrial cleaning equipment and cleaning chemicals. Furthermore, any fasteners permanently attached to the curtain, especially any portion that is more frequently cleaned, can degrade over time due to exposure to such equipment and chemicals and can result in more frequent—and, thus, more costly—repair and/or replacement of the curtains. Furthermore, permanent attachment of fasteners to the curtain can result in a higher cost to manufacture the curtain originally—including higher manufacturing equipment, higher material cost, and higher labor cost—versus a curtain or portion thereof requiring no fasteners. The snap hook system can be configured for use with—and can be used with—a disposable curtain, which can be removed and/or discarded to prevent future contamination.

FIG. 1 is a front elevation view of an object 60 in accordance with one aspect of the current disclosure. The object 60, which can be a curtain, can be suspended from a track 50, which can be secured to a ceiling 40 of an interior space such as, for example and without limitation, a room in a hospital, clinic, or nursing home. More specifically, the track 50 can comprise one or more carriers 55. The curtain 60 can comprise an upper section or upper panel 70. The upper section 70 of each privacy curtain can be made of or can comprise a netting or mesh material 71.

The curtain 60 can further comprise a lower section or lower panel 80, which can be removably secured to and suspended from the upper section 70. The lower section 80 can be secured to the upper section 70 via one or more fasteners 90. More specifically, each of or any of the one or more fasteners 90 can be removably secured to the upper section 70. In some aspects, as shown, a plurality of the fasteners 90 can be aligned horizontally. Each of the plurality of the fasteners 90 and, more specifically, a center or axis thereof can be positioned a first spacing distance or first spacing or vertical spacing 191 from a horizontal edge of the upper section 70. In some aspects, as also shown, each pair of adjacent fasteners 90 of the plurality of the fasteners 90 and, more specifically, centers or axes thereof can be spaced apart by a second spacing distance or second spacing or horizontal spacing 192. Two or more of the curtain 60, the fasteners 90, and other structural elements or portions of any of the structural elements disclosed herein can together form a system 30.

The curtain 60 can define a top end 63, a bottom end 64, a first side end 65, and a second side end 66. The upper section 70 of the curtain 60 can define a top end 73, a bottom end 74, a first side end 75, and a second side end 76. The lower section 80 of the curtain 60 can define a top end 83, a bottom end 84, a first side end 85, and a second side end 86. As shown, the top end 83 of the lower section 80 can be secured to the bottom end 74 of the upper section 70. In some aspects, as shown, each of the upper section 70 and the lower section 80 can define or comprise a single, one-piece panel. In some aspects, each of the upper section 70 and the lower section 80 can define a plurality of panels, which can be lined up side-by-side, with or without overlap as may be desired or required by a particular end-use. Where the panels of the upper section 70 and/or the lower section 80 are divided, one or more fasteners 90 can support adjacent (e.g., side-by-side) panels so as to facilitate such overlapping arrangement. More specifically, the one or more fasteners 90 can be removably inserted in one of a plurality of openings 88 defined in the lower section 80, which openings 88 can be spaced apart by the second spacing 192 or spacing that is greater than or less than the second spacing 192.

Each of or any of the plurality of fasteners 90 can be a snap fastener. Each of or any of the one or more fasteners 90 can comprise a first portion or snap member 100 and a second portion or mating snap member 700 (shown in FIG. 7).

FIG. 2 is a top front perspective view of the first portion or snap member 100 of one of the plurality of fasteners 90 of FIG. 1. The snap member 100 can comprise a base 210. The base 210 can define a first side 211 (shown in FIG. 3), which can define a first side surface 213 (shown in FIG. 3). The base 210 can define a second side 212, which can define a second side surface 214. The base 210 can define an outer edge 215, which can define an outer edge surface 217 and can be cylindrical or substantially cylindrical in shape (“substantially cylindrical” meaning having an overall shape that is cylindrical, ignoring local interruptions to that overall shape that do no extend around the full circumference of the outer edge 215 as well as draft angles of five degrees or less that facilitate manufacturability of the snap member 100). In some aspects, as shown, the base 210 can define a disc shape. More specifically, the base 210 can define a circular shape in cross-section and, more specifically, in radial cross-section, where a radial cross-section lies in a viewing plane that is perpendicular to an axis 221 of the snap member 100. In some aspects, the base 210 can define a non-disc shape or a non-circular shape in cross-section and, more specifically, in radial cross-section.

The snap member 100 can comprise a first engagement portion 220, which can extend from the base 210 in a first direction 203. The first direction 203 can be aligned with the axis 221 of the snap member 100. More specifically, the snap member 100 can be configured to engage with a mating engagement portion or first engagement portion 720 (shown in FIG. 7) of the mating snap member 700 (shown in FIG. 7). The first engagement portion 220 can comprise a protrusion 223, which can define a proximal or first end 225 (shown in FIG. 3) and a distal or second end 226. More specifically, the protrusion 223 can define an axial height 227 (shown in FIG. 6). The first engagement portion 220 can define a cavity 228 (shown in FIG. 3), which can be defined in the protrusion 223. More specifically, the cavity 228 can define an axial depth 229 (shown in FIG. 6). An axis 233 of the protrusion 223 and an axis 238 of the cavity 228 can be collinear. In some aspects, the first engagement portion 220 can define rotational symmetry about the axis 221. At least a portion of the first side 211 and, more specifically, the first side surface 213 can be planar.

Defined in further detail below, an outer diameter 627 (shown in FIG. 6) of the first engagement portion 220 at the second end 226 can be larger than at the first end 225. In some aspects, a maximum value of the outer diameter 627 of the first engagement portion 220 can be configured to decrease during assembly of the first engagement portion 220 with the first engagement portion 720 of the mating snap member 700 to allow and facilitate insertion in and locking engagement of the first engagement portion 220 with the first engagement portion 720. As shown, the first engagement portion 220 can define one or more bulbous tips or ribs 250 at the second end 226, which can further facilitate locking engagement of the first engagement portion 220 with the first engagement portion 720.

The snap member 100 can comprise a second engagement portion or hook portion 240, a portion of which can extend from the base 210 in a second direction 204. In some aspects, as shown, the second direction 204 can be angled with respect to the axis 221 of the snap member 100 and/or the first direction 203. In some aspects, the second direction 204 can be aligned with the axis 221 of the snap member 100 and/or the first direction 203. The hook portion 240 can define a proximal or first end 245 and a second or distal end 246, which can define a radius or, more specifically, a full spherical radius to ease insertion of the distal end 246 through the opening 88. The hook portion 240 can comprise a hook or hook member and can define a hook shape, which can include any shape that an object such as, for example and without limitation, the lower section 70 (shown in FIG. 1) of the curtain 60 (shown in FIG. 1) can hang or catch on. In some aspects, the object 60 need not be a curtain per se and can be or can comprise bird netting, insect netting, a tarpaulin or tarp, or any other panel. In some aspects, the object 60 and, more specifically, the curtain 60 can be flexible and can comprise a flexible material that is configured to be folded or bunched up when not fully deployed or extended. In some aspects, the curtain 60 can be comprise a fabric material. In some aspects, the curtain 60 can be comprise a polymer material. The snap member 100 and one or more portions thereof such as the base 210 and the hook portion 240 can define a space or gap 218 therebetween for passage of a portion of an object such as a top end 83 of the curtain 60. The gap 218 can be made more open to ease disengagement and removal of the lower section 80. The gap 218 can be made tighter to make disengagement and removal of the lower section 80 more difficult, which can help avoid accidental or unauthorized removal of the curtain 60 and, more specifically, the lower section 80. In some aspects, as shown, the hook portion 240 can define a tangent line or axis 241. As also shown, the hook portion 240 can define one or more straight portions (e.g., a straight portions 243a,b,c) and/or one or more curved portions (e.g., curved portions 244a,b,c). The presence of the one or more curved portions can facilitate bending of the hook portion 240 without exceeding the yield strength of a material forming the hook portion 240 (for example only, by reducing stress concentrations resulting from sharp or immediate turns between two adjoining portions such as two adjoining straight portions). Similarly, one or more transition portions 219a,b between the base 210 and the hook portion 240 can define a radius R219 (shown in FIG. 5), and any other transition portion can define a radius. For example and without limitation, the transition portion 419 (shown in FIG. 4) can define a radius R419 (shown in FIG. 4). In some aspects, a portion of the hook portion 240 can be understood as extending from the base 210 in a direction opposite from the direction 203. More specifically, a portion of the hook portion 240 can protrude or extend from the second side 212 and, more specifically, the second side surface 214 of the base 210. At least a portion of the second side 212 and, more specifically, the second side surface 214 can be planar.

FIG. 3 is a top rear perspective view and FIG. 4 is a bottom rear perspective view of the first portion or snap member 100 of the fastener 90 of FIG. 1. As shown, a portion of the first side 211 and, more specifically, the first side surface 213 can define a flange 311, which can extend in an axial direction beyond a surrounding portion of the first side 211 by a flange height or distance 611 (shown in FIG. 6). In some aspects, the flange 311 can facilitate a secure connection and seal between the snap member 100 and the mating snap member 700. In some aspects, the flange 311 can prevent or reduce rotation of the hook portion 240 with respect to the base 210, including when the snap member 100 is carrying a load. More specifically, the flange 311 can prevent or reduce such rotation or, more generally, movement with respect to the base 210 by closing or reducing any gap between the hook portion 240 and the base 210. The cavity 228 can define a bottom surface 328.

FIG. 5 is a top view of the first portion or snap member 100 of the fastener 90 of FIG. 1. As shown, the axis 241 can be aligned in the same plane as (i.e., can be coplanar with) the axis 233 and/or the axis 238. In alignment with both the axis 233 and the axis 238, a load born by the hook portion 240 can be born equally by each left and right side of the first engagement portion 220, which can facilitate continued engagement of the first engagement portion 220 and, more generally, the snap member 100 with the mating snap member 700. In some aspects, the proximal or first end 245 can be a portion of the snap member 100 that protrudes from the base 210 and, more specifically, the second side 212 and second side surface 214 thereof, which again can be planar, substantially planar, or substantially flat. “Substantially planar” means having an overall surface that is planar, ignoring local interruptions to that overall shape, e.g., textural features. “Substantially flat” means having an overall surface that is featureless, ignoring local interruptions to that overall shape, e.g., textural features, and not requiring that the overall surface be planar and, rather, allowing the second side 212 and the second side surface 214 to define, for example and without limitation, a convex or a concave shape).

FIG. 6 is a partial sectional view of the first portion or snap member 100 of the fastener 90 of FIG. 1 taken along line 6-6 of FIG. 5. Again, the first engagement portion 220 can comprise the protrusion 223 defining the axial height 227 and the cavity 228 defined therein and defining the axial depth 229. As shown, the axis 241 at the curved portions 244a,b,c can define respective radii R244a,b,c. In some aspects, the hook portion 240 and, more generally, the snap member 100 can define a minimum open width 661 and a maximum open width 662 in a Y-axis direction (shown in FIG. 2). In some aspects, a portion of the hook portion 240 such as the straight portion 243c can be angled with respect to the vertical by a tilt angle 640 and, more specifically, can be angled with respect to the down vertical direction or the second direction 204. A tilt angle 640 that results from an axis or a tangent line of the distal or second end 246 of the hook portion 240 being angled towards the user when the user faces the second side 212 of the snap member 100, as shown, can facilitate engagement of the lower section 80 with each of the fasteners 90 (shown in FIG. 1).

In some aspects, as shown, the hook or hook shape can comprise at least one member defining a tangent line or axis 241 that is angled by a hook angle 670 measuring at least 90 degrees with respect to the downward vertical direction (or an upward vertical direction, if the gap 218 is viewable from below the snap member instead of above the snap member when installed), the vertical direction, and/or the second direction 204. In some aspects, as shown, the hook angle 670 of the tangent line or axis 641 of at least member of the hook portion 240 can be at least 180 degrees with respect to the downward vertical direction, the vertical direction, and/or the second direction 204. The hook angle 670 is shown only for the first straight portion 243a, but a hook angle can be similarly drawn and measured between, on a first end, the downward vertical direction, the vertical direction, and/or the second direction 204 and, on a second end, the axis 241—or a tangent line either of the axis 241 or else defined by the straight portion 243a,b,c or curved section 244a,b,c itself. In some aspects, including when the portion of the hook portion 240 is angled with respect to the vertical by a tilt angle 640, the hook angle 670 can measure more than 90 degrees and less than 180 degrees. If, in other aspects, the hook angle 670 is measured from a horizontal line extending from the base 210 towards the hook portion 240, the hook angle 670 can measure at least zero degrees with respect to such a horizontal direction, can measure at least 90 degrees with respect to such a horizontal direction, or can measure more than zero degrees and less than 90 degrees. In some aspects, the hook angle 670 as measured to at least one member of the second engagement portion can be as described herein.

In some aspects, as shown, the hook portion 240 can, together with the base 210 and/or the first engagement portion 220, form a monolithic or one-piece structure therewith. In some aspects, the hook portion 240 can be formed separately and can be attached to the base 210 and, more generally, a remaining portion of the snap member 100. More specifically, the hook portion 240 can be fastened or secured to the base 210.

FIG. 7 is a front perspective view of the second portion or mating snap member 700 of the fastener 90 of FIG. 1, and FIG. 8 is a sectional view of the second portion or mating snap member 700 of FIG. 7 taken along line 8-8 of FIG. 7. The mating snap member 700 can be configured to be received within or, as shown in FIG. 11, can be configured to receive the first portion or snap member 100. The mating snap member 700 can comprise a base 710. The base 710 can define a first side 711 (shown in FIG. 8), which can define a first side surface 713 (shown in FIG. 8). The base 710 can define a second side 712, which can define a second side surface 714. The base 710 can define an outer edge 715, which can define an outer edge surface 717 and can be cylindrical or substantially cylindrical in shape (“substantially cylindrical” meaning having an overall shape that is cylindrical, ignoring local interruptions to that overall shape that do no extend around the full circumference of the outer edge 715 as well as draft angles of five degrees or less that facilitate manufacturability of the mating snap member 700). In some aspects, as shown, the base 710 can define a disc shape. More specifically, the base 710 can define a circular shape in cross-section and, more specifically, in radial cross-section, where a radial cross-section lies in a viewing plane that is perpendicular to an axis 721 of the mating snap member 700. In some aspects, the base 710 can define a non-disc shape or a non-circular shape in cross-section and, more specifically, in radial cross-section.

The mating snap member 700 can comprise a first engagement portion 720, which can extend from the base 710 in a first direction 703. The first direction 703 can be aligned with the axis 721 of the mating snap member 700. More specifically, the mating snap member 700 can be configured to engage with a first engagement portion 220 (shown in FIG. 6) of the snap member 100 (shown in FIG. 7). The first engagement portion 720 can comprise a protrusion 723, which can define a proximal or first end 725 and a distal or second end 726. More specifically, the protrusion 723 can define an axial height 727 (shown in FIG. 8). The first engagement portion 720 can define a cavity 728, which can be defined in the protrusion 223. More specifically, the cavity 728 can define an axial depth 729 (shown in FIG. 8). An axis 733 of the protrusion 723 and an axis 738 of the cavity 728 can be collinear. In some aspects, the first engagement portion 720 can define rotational symmetry about the axis 721. At least a portion of the first side 711 and the first side surface 712 thereof and the first side surface 713 thereof can be planar or can extend in a radial direction as shown.

Defined in further detail below, an inner diameter 737 (shown in FIG. 8) of the first engagement portion 720 at the second end 726 can be smaller than the inner diameter 737 when measured at the first end 725. In some aspects, a minimum value of an inner diameter 737 of the first engagement portion 720 can be configured to increase during assembly of the first engagement portion 720 with the first engagement portion 220 of the snap member 100 to allow and facilitate insertion in and locking engagement of the first engagement portion 220 with the first engagement portion 720. As shown, the first engagement portion 720 can define one or more bulbous tips or ribs 750 at the second end 226, which can further facilitate locking engagement of the first engagement portion 220 with the first engagement portion 720. More specifically, the one or more ribs 750 can interact or engage with the one or more ribs 250 of the first engagement portion 220 to hold the snap member 100 to the mating snap member 700 until purposely disengaged by a user with a sufficient separation force. In some aspects, also as shown, a plurality of the ribs 750 can extend circumferentially around the cavity 728, and adjacent ribs 750 can define a gap therebetween to allow the ribs to ribs 750 to more easily flex upon engagement with the snap member 100.

The mating snap member 700 can comprise a second engagement portion 740, a portion of which can extend from the base 710 in a second direction 704 or can be considered part of the base 710. In some aspects, as shown, the second direction 704 can be aligned with the axis 721 of the mating snap member 700 and/or the first direction 703. In some aspects, the second direction 704 can be angled with respect to the axis 721 of the mating snap member 700 and/or the first direction 703. The second engagement portion 740 can define a proximal or first end 745 and a distal or second end 746. The second engagement portion 740 can comprise one or more anti-rotation features 749, which can facilitate fixation of an angular position of the mating snap member 700 with respect to an object such as, for example and without limitation, the curtain 60 (shown in FIG. 1) through which the mating snap member 700 can be secured. The mating snap member 700 and, more specifically, the base 710 and/or one or more other portions of the mating snap member 700 can define an opening 718 for passage of a fastening structure 1110 (shown in FIG. 11), which can also extend through an object such as a portion of the upper section 70 of the curtain 60 proximate to the bottom end 74. At least a portion of the second side 712 and, more specifically, the second side surface 714 can be planar.

FIG. 9 is a front perspective view of the upper section 70 of the curtain 60 of FIG. 1 with the first portion or snap member 100 of the fastener 90 of FIG. 1 secured thereto. In some aspects, as shown, the fastener 90 can be positioned proximate to an intersection of the lower end 74 and the first side end 75 of the upper section 70 of the curtain 60. In some aspects, the fastener 90 can be positioned at any desired position along the curtain and, more specifically, the upper section 70 thereof. In some aspects, the snap member 100 and the mating snap member 700 can be specified and installed together.

In some aspects, the snap member 100 can be sized and otherwise configured to install in pre-existing mating snap member 700 and thus enabling re-use of an existing upper section 70. Given the number of curtains 60 in some facilities, the cost of replacement, and the consideration that the lower sections 80 of the curtain 60 are most vulnerable to soiling and wear due to cleaning, it can be particularly advantageous to be able to hang a pre-punched curtain (i.e., punched with the openings 88) onto an existing hospital privacy curtain (e.g., the upper section 70) and not be limited to products made specifically to fit with the included hardware, whether snap or otherwise. In some aspects, each of the snap member 100 and the mating snap member 700 of the fastener 90 need not be snap members and need not form a snap fastener. For example and without limitation, the snap member 100 and the mating snap member 700 can be joined via a magnetized connection using, for example and without limitation, a magnet in one of the first portion 100 and the mating snap member 700 and a second disc magnet or simply a magnetic material in the other of the first portion 100 and the mating snap member 700. With the snap fasteners 90, however, a user (e.g., an employee responsible for handling the cleaning of the curtains 60 in the facility) can simply hang the lower section 80 from an existing snap socket or mating snap member 700 through the snap member 100. Without needing to engage or disengage any snapped connections, taking significantly more time and energy, the user can hang and take down the curtain 60 by simply lifting the top end 83 over the hook portion 240 of the snap member 100 to install or remove. Improved ease of attachment and removal of the lower section 80 not only reduces the difficulty of the work but increases safety. If the user decides to access the connection between the lower section 80 and the upper section 70 via a step stool or ladder, for example, the user can spend less time on the ladder and exert less force, thereby reducing the risk that they might in the process fall from the ladder.

FIG. 10 is a front perspective view of the lower section 80 of the curtain 60 of FIG. 1 engaged with and suspended from the first portion or snap member 100 of the fastener 90 of FIG. 1, which again is secured to the upper section 70 of the curtain 60. In some aspects, as shown, the hook portion 240 of each of the one or more fasteners 90 can be removably received—and securably received—within one of a plurality of openings 88 defined in the lower section 80 of the curtain 60. In some aspects, the components of the fastener 90 can be rearranged in various ways. For example and without limitation, the mating snap member 700 can be secured to the lower section 80, the snap member 100 can be engaged with the hook portion 240, and with the distal end 246 of the hook portion 240 pointing downward instead of upward the hook portion 240 can be received within the openings 88 when defined along and proximate to a lower end 74 of the upper section 70. In some aspects, a height 1040 of the hook portion 240 can be greater than a height 1080 of the opening 88 to help secure the lower section 80 to the one or more fasteners 90. In some aspects, a height 1040 of the hook portion 240 can be less than a height 1080 of the opening 88 to ease removal and reinstallation of the lower section 80.

FIG. 11 is a sectional view of the assembly of FIG. 9 and, more generally, the system 30 showing also the lower section 80 of FIG. 1 as it is being placed over the fastener 90 and, more specifically, the first portion or snap member 100 thereof. The mating snap member 700 can be secured to the curtain 60 and, more specifically, the upper section 70. The fastening member or fastening structure 1110 (e.g., a button 1120 comprising a stud 1190) can be assembled along an axis 1111. More specifically, the fastening structure 1110 can be passed, at least in part, through an opening 78 defined in the upper section 70, and the stud 1190, which can be a rivet, can be deformed or otherwise made to engage with the mating snap member 700 and thereby secure the mating snap member 700 to the curtain 60.

Again, as shown, each of or any of a plurality of the second portions or mating snap members 700 can be secured to the upper section 70, and each of or any of a plurality of the first portions or snap members 100 can be removably secured to one of the second portions or mating snap members 700. More specifically, a hook portion 240 of each of one of the plurality of fasteners 90 (e.g., the hook portion of the snap member 100) can be removably inserted in one of the plurality of openings 88 defined in the lower section 80. In some aspects, each of or any of a plurality of the second portions or mating snap members 700 can be secured to the lower section 80, and each of or any of a plurality of the snap members 100 can be removably secured to one of the second portions or mating snap members 700.

In some aspects, the first engagement portion 220 can comprise one of a male engagement portion or stud, as shown, and a female engagement portion or socket; and the first engagement portion 720 of the mating snap member 700 can comprise one of the female engagement portion and the male engagement portion. More specifically, as shown, the first engagement portion 220 can comprise the male engagement portion; and the mating snap member 700 can comprise the female engagement portion.

FIG. 12A is a top rear perspective view and FIG. 12B is a bottom rear perspective view of a first portion or snap member 1200 of the fastener 90 of FIG. 1 in accordance with another aspect of the current disclosure. Note that, in the alternative, the snap member 1200 can be defined or identified as the snap member 100 but is renumbered in some figures as the snap member 1200 for convenience. The snap member 1200 can comprise one or more stabilizers or legs 1250. Each of the legs 1250 can define a base or first end or proximal end 1252 and a tip or second end or distal end 1254. The distal end 1254 can define a planar surface. In some aspects, each of the legs 1250 can define a taper from the proximal end 1252 to the distal end 1254. In some aspects, a width or thickness of the distal end 1254 of each of the legs 1250 can otherwise be smaller or narrower than the a width or thickness of the proximal end 1252. In some aspects, as shown, the legs 1250 can extend from a portion of the outer edge 215 and, more specifically, the outer edge surface 217. In some aspects, the legs 1250 can extend from a portion of the first side 211 and, more specifically, the first side surface 213. Each of the legs 1250 can extend in an axial direction beyond a surrounding portion of the base 210 by a leg height or distance 1206 (shown in FIG. 12C). In some aspects, each of the one or more legs 1250 can facilitate a secure connection and seal between the snap member 100 and the mating snap member 700. In some aspects, each of the one or more legs 1250 can prevent or reduce rotation of the hook portion 240 with respect to the mating snap member 700 or the base 710 thereof or, as will be described below, a mating snap member 1300 or a base 1310 thereof, including when the snap member 1200 is carrying a load. More specifically, each of the one or more legs 1250 can prevent or reduce such rotation or, more generally, movement with respect to the mating snap member 700,1300 by contacting the base 210, the side 215, and/or the curtain 60. Again, the cavity 228 can define a bottom surface 328.

FIG. 12C is a cross-sectional view of the snap member 1200 taken along a similar axis as line 6-6 in FIG. 5. In various aspects, the snap member 1200 can comprise or define the same features described with respect to the snap member 100, including with respect to any one or more subparts thereof. In some aspects, however, the open width 661 defined by the snap member 1200 can be reduced and a distal or second end 246 of the snap member 1200 and, more specifically, the hook portion 240 can be oriented nearer to the second side 212 and, more specifically, the second side surface 214 or a base plane 1210 of the snap member 1200, e.g., as compared to snap member 100 shown in FIG. 6, which base plane 1210 can be defined by the second side 212 or the second side surface 214 thereof. An open width 1261, which can be a distance between a portion of the base plane 1210 and a portion of the hook portion 240 that are closest to each other, can be oriented at an angle to the horizontal or vertical directions.

The snap member 1200 can define a total depth 1202, which is greater than the axial depth 229, at least because each of the one or more legs 1250 can extend beyond the second end 226 of the protrusion 223 by a distance 1204. Again, the first engagement portion 220 can comprise a protrusion 223, which can define the axial height 227 and the cavity 228. The first engagement portion 220 can define or set the axial depth 229 relative to the axial height 227 and/or cavity 228. The hook portion 240 can form or comprise a hook shape or hook 1240 and can define the axis 241. Each of the curved sections 244a,b can define the corresponding radius e.g., the radius R244a,b,c, respectively. In various aspects, the minimum open width 661 can be equal to the maximum open width 662.

In some aspects, as shown, a section of the hook portion 240, e.g., the straight section 243c, can be aligned with the vertical or substantially parallel to the vertical. In some aspects, a section of the hook portion 240, e.g., the straight section 243c, can be tilted in one direction or another relative to the vertical at the tilt angle 640. In some aspects, the distal or second end 246 of the hook portion 240 can be angled away from the user when the user is facing the second side 212 of the snap member 1200. In some aspects, the distal or second end 246 of the hook portion 240 can be angled toward the user when the user is facing the second side 212 of the snap member 1200. This arrangement can enhance the engagement of the lower section 80 with each of the fasteners 90 (shown in FIG. 1) by, for example, making it more difficult to inadvertently disengage and remove the curtain 60 from the fasteners 90 by passage of the hook portions 240 thereof through the plurality of openings 88 defined in the lower section 80.

The gap 218 (e.g., the distance 661 or the distance 1261) can be smaller to prevent inadvertent removal of the curtain 60. Because the gap 218 and, more specifically, the open width 261 is smaller, an inadvertent tug, pull or push, jostle, or yank is less likely to dislodge or remove a portion of the curtain 60 from the hook 1240.

When the tilt angle 640 is a non-zero angle between 0 and 90 degrees, the hook angle 670 can, when measured to a portion of the axis 241 defined by the distal or second end 246, measure more than 90 degrees but less than 180 degrees. When the tilt angle 640 is a non-zero angle between 0 and minus 90 degrees, the hook angle 670 can, when measured to the portion of the axis 241 defined by the distal or second end 246, measure more than 180 degrees.

FIG. 13 is a perspective view of a mating snap member 1300 of the snap member 1200 of FIG. 12A, and FIG. 14 is a cross-sectional view of the mating snap member 1300 taken along line 14-14 of FIG. 13. In various aspects, the mating snap member 1300 can comprise or define the same features described with respect to the mating snap member 700, including with respect to any one or more subparts thereof. The mating snap member 1300 can consist of a base 1310, which can define a first side 1311 (shown in FIG. 14) and, more specifically, a first side surface 1313 (shown in FIG. 14). Additionally, the base 1310 can define a second side 1312, which can define a second side surface 1314. The base 1310 can define an outer edge 1315, which can define an outer edge surface 1317 and can be cylindrical or substantially cylindrical in shape. The term “substantially cylindrical” refers to an overall cylindrical shape while disregarding minor interruptions that do not extend around the full circumference of the outer edge 1315, as well as draft angles of five degrees or less that aid in the manufacturability of the mating snap member 1300.

In some aspects, as shown, base 1310 can take the form of a disc. more specifically, the base 1310 can have or define a circular shape in cross-section, including in radial cross-section, where a radial cross-section is viewed in a plane that is perpendicular to an axis 1321 of the mating snap member 1300. In some aspects, the base 1310 can have or define a non-circular shape in cross-section, including in radial cross-section.

The mating snap member 1300 can comprise a first engagement portion 1320, which can extend from the base 1310 in a first direction 1303. The first direction 1303, can be aligned with the axis 1321 of the mating snap member 1300. More specifically, the mating snap member 1300 can be configured to engage with a first engagement portion 220 of the snap member 1200 (shown in FIG. 12C). The first engagement portion 1320 can comprise a protrusion 1323, which can define a proximal or first end 1325 and a distal or second end 1326. More specifically, the protrusion 1323 can define an axial height 1327 (shown in FIG. 14). The first engagement portion 1320 can define a cavity 1328. The cavity 1328 can define an axial depth 1329 (shown in FIG. 14). An axis 1333 of the protrusion 1323 and an axis 1338 of the cavity 1328 can be collinear. The first engagement portion 1320 can define rotational symmetry about the axis 1321. At least a portion of the first side 1311 and, more specifically, the first side surface 1313 thereof can be planar or can extend in a radial direction as shown.

An inner diameter 1337 (shown in FIG. 14) of the first engagement portion 1320 at the second end 1326 can be smaller than the inner diameter 1337 when measured at the first end 1325. A minimum value of the inner diameter 1337 of the first engagement portion 1320 can be configured to increase during assembly of the first engagement portion 1320 with the first engagement portion 220 of the snap member 1200 to allow and facilitate insertion in and locking engagement of the first engagement portion 220 of the snap member 1200 with the first engagement portion 1320 of the mating snap member 1300. As shown, the first engagement portion 1320 can define a snap ring or ring 1350, which can further facilitate locking engagement of the first engagement portion 220 of the snap member 1200 with the first engagement portion 1320 of the mating snap member 1300. The ring 1350 or, as disclosed above, various rib(s) 750 can interact or engage with the bulbous tip(s) or rib(s) 250 of the first engagement portion 220 to hold the snap member 1200 to the mating snap member 1300 until purposely disengaged by a user with a sufficient separation force. In some aspects, the ring 1350 or a plurality of the ribs 750 can extend circumferentially around the cavity 1328. More specifically, the ring 1350 can increase in diameter during engagement of the first engagement portion 220 and a maximum diameter thereof with the ring 1350. The ring 1350 can decrease in diameter during final engagement to securably engage with the first engagement portion 220.

The mating snap member 1300 can comprise a second engagement portion 1340, which can extend from the base 1310 in a second direction 1304 or can be considered part of the base 1310 itself. As illustrated, the second direction 1304 can align with the axis 1321 of the mating snap member 1300 and/or the first direction 1303. In other instances, the second direction 1304 can be angled in relation to the axis 1321 of the mating snap member 1300 and/or the first direction 1303.

The second engagement portion 1340 can define a proximal (or first) end 1345 and a distal (or second) end 1346. The portion defined between the proximal end 1345 and the distal end 1346 can be circular and/or can include one or more anti-rotation features as described above, to secure the angular position of the mating snap member 1300 relative to an object, such as the curtain 60 (shown in FIG. 1) to which the mating snap member 1300 can be attached. For example and without limitation, the mating snap member 1300 (or, for that matter, the mating snap member 700 shown in FIG. 7) can comprise one or more legs such as the leg 1250, which can prevent rotation of the snap member 1200 with respect to the mating snap member 1300 (or the mating snap member 700).

The base 1310 and/or other segments of the mating snap member 1300 can define an opening 1318, which can be configured for the passage of a fastening member or fastening structure 1510 (shown in FIG. 15). At least a portion of the second side 1312 and the second side surface 1314 thereof can be planar or can extend in a radial direction as shown.

FIG. 15 is a sectional view of an assembly with the snap member 1200 of FIG. 12 and the mating snap member 1300 of FIGS. 13-14 as assembled to the curtain 60 of FIG. 1. In various aspects, fastening structure 1510 is the same as or similar to fastening structure 1110. As such, the fastening structure 1510 can be received in or can extend through an object such as, for example and without limitation, the upper section 70 of the curtain 60 and, more specifically, the bottom end 74 thereof. In various aspects, the fastening structure 1510 can comprise or define the same features described with respect to the fastening structure 1100, including with respect to any one or more subparts thereof.

In some aspects, as shown, the mating snap member 1300 of the fastener 90 can receive the first portion or snap member 1200. In some aspects, the mating snap member 1300 can be received within the snap member 1200. More specifically, a system 30 can comprise the snap member 1200, the mating snap member 1300, and the curtain 60. The system 30 is depicted with the lower section 80 of the curtain 60 positioned over the snap member 1200. In some aspects, the mating snap member 1300 can be attached to the curtain 60 and, more specifically, to the upper section 70 by assembling the fastening member or fastening structure 1510 (e.g., a button 1520, which can include a stud 1590) along the axis 1511. The fastening structure 1510 can be at least partially passed through an opening 78 in the upper section 70. The stud 1590, which could be in the form of a rivet, can be deformed or manipulated to engage with the mating snap member 1300, which can thereby secure the mating snap member 1300 to the curtain 60.

Any of a plurality of mating snap members 1300 can be attached to the upper section 70, and the snap members 1200 can be removably secured to one of the second portions or mating snap members 1300. Specifically, the hook portion 240 of each fastener 90 (including, for example, the hook portion of the snap member 100 or snap member 1200) can be inserted into one of the openings 88 defined in the lower section 80. In certain cases, any of the plurality of second portions or mating snap members 1300 can also be secured to the lower section 80, with each snap member 100 being removably secured to one of the second portions or mating snap members 1300.

In some aspects, the first engagement portion 220 of the snap member 1200 can comprise one of a male engagement portion or stud, as shown, and a female engagement portion or socket. The first engagement portion 1320 of the mating snap member 1300 can also consist of one of these female engagement portion or the male engagement portions. More specifically, as shown, the first engagement portion 220 can comprise the male engagement portion; and the mating snap member 1300 can comprise the female engagement portion.

A method of using the snap member 100 can comprise removably securing the first engagement portion 220 of the snap member 100 to a first object. More specifically, the method can comprise removably securing the snap member 100 to one of the upper section 70 and a lower section 80 of the curtain 60. The method can comprise removably receiving the hook portion 240 of the snap member 100 within the opening 88 defined in a second object. More specifically, the method can comprise removably securing the other of the upper section 70 and the lower section 80 to the snap member 100. The method can comprise disengaging the second object from the snap member 100 without removing the snap member 100 from the first object. More specifically, the method can comprise disengaging the other of the upper section 70 and the lower section 80 from the snap member 100 without removing the snap member 100 from the one of an upper section 70 and the lower section 80 of the curtain 60. In some aspects, the method can comprise contacting the mating snap member 1300 with the snap member 1200 and, more specifically, one or more of the legs 1250 thereof and thereby securing a rotational position of the snap member 1200 with respect to the mating snap member 1300. In some aspects, the method can comprise contacting the curtain 60 with the snap member 1200 and, more specifically, one or more of the legs 1250 thereof and thereby securing a rotational position of the snap member 1200 with respect to the curtain 60.

In some aspects, various components of the fastener 90 can be formed from or comprise a metal such as, for example and without limitation, carbon steel, stainless steel, or brass. In some aspects, various components of the fastener 90 can be formed from or comprise a non-material material such as, for example and without limitation, a plastic resin, e.g., a polyacetal resin. More specifically, a portion of the fastener 90 such as the snap member 100 can be formed from polyacetal. In some aspects, the various components can be formed from any other material, any of which can optionally be corrosion-resistant or replaceable for serviceability. In some aspects, the various components of the fastener 90 can be formed from different materials. For example and without limitation, the mating snap member 700 and the fastening structure 1110 can be formed from metal and the snap member can be formed from plastic. The various components of the fastener 90 can be formed from any one or more of a variety of manufacturing processes. For example and without limitation, one or more components can be fabricated using subtractive manufacturing processes such as machining, forging, casting, stamping; additive manufacturing processes such as three dimensional printing; and any other forming and assembly processes such as bending and riveting.
