Patent Application
20220183413
This disclosure relates to a device for retaining a garment on a wearer, and, in particular, to a device and method for safely retaining a face covering on a wearer.
To prevent the transmission of pathogens, people will often wear a face mask to reduce the expulsion or intrusion of aerosols. One type of face mask that has become popular is a bandana formed by folding a rectangular piece of cloth into a triangle that can then be tied behind the wearer's neck.
In one aspect a garment clasp is provided, the garment clasp including a first substantially planar body having a proximal end portion, a distal end portion and a central portion, the distal and proximal end portions each having a width greater than a width of the central portion, the elongated body defining three or more passages therethrough, a first passage at the proximal end portion, a second passage at the distal end portion and a central passage positioned between the first and second passage, and a second substantially planar body having a proximal end portion, a distal end portion and a central portion, the distal and proximal end portions each having a width greater than a width of the central portion, the second elongated body defining three or more passages therethrough, a first passage at the proximal end portion, a second passage at the distal end portion and a central passage positioned between the first and second passage, wherein the width of the proximal portion of the first body is greater than a width of the first passage in the second body and the proximal portion of the first body can be deformed by the wearer to pass through the first passage in the second body, removably securing the first body to the second body.
The first substantially planar body and the second substantially planar body can be identical. The width of the central portion of the first body can be equal to or less than the width of the first passage in the second body. The planar bodies may be comprised of a polymer selected from one of EVA, silicone, PVC, polyamide and polyurethane and may include a score line, indent or perforation. The garment clasp is designed to fail when a tensile force of greater than 5, greater than 10, greater than 20 N, greater than 50 N, or greater than 100 N is applied. The first passage in the second body can be deformed to allow the proximal portion of the first body to pass through the first passage. At least the first substantially planar body can be symmetrical. A garment can include any of these embodiments and additionally a bandana including two opposed corners wherein a first corner is threaded through two of the passages of the first planar body and a second corner is threaded through two of the passages of the second planar body.
In another aspect, a method is provided, the method comprising folding a rectangular piece of cloth to produce a substantially right triangle having a 90 degree point, a first 45 degree point and a second 45 degree point, threading the first 45 degree point through a first passage in a first planar connector and subsequently through a second passage in the first planar connector, threading the second 45 degree point through a first passage in a second planar connector and subsequently through a second passage in the second planar connector, and connecting the first planar connector to the second planar connector by deforming one end of the first planar connector and passing it through a third passage in the second planar connector. The method can include releasing the bandana by applying adequate tension to de-thread at least one of the 45 degree points from the first or second planar connector. Releasing the bandana can be done by applying adequate tension to separate the first planar connector from the second planar connector. Enough tension may be applied to break at least one of the first planar connector and the second planar connector. The method may include deforming the third passage in the second planar connector to facilitate passage of the one end of the first planar connector. The wearer can thread the 45 degree points prior to placing the cloth around their head and then connects the first and second planar connectors after placing the cloth around their head. The tensile force applied can be applied quickly enough that the 45 degree points cannot unthread and the planar connectors do not separate.
The systems, devices and methods described herein may be used separately or together, and components or techniques described in relation to one system or method are capable of being implemented with the others. The subject matter of this application may involve, in some cases, interrelated products, alternative solutions to a particular problem, and/or a plurality of different uses of a single system or article.
The above-mentioned and other features of this disclosure, and the manner of attaining them, will become more apparent and better understood by reference to the following description of embodiments described herein taken in conjunction with the accompanying drawings, wherein:
Bandanas have become a popular form of face mask and are in wide use throughout the world. To form a bandana, a wearer typically folds a rectangular (often square) piece of cloth into a triangle by joining two opposing corners together. The corners that were not folded towards each other form points of approximately 45 degrees each. The user ties these points together behind their neck to secure the bandana in place. Once tied, the bandana is not adjustable and is so securely tied behind the neck of the wearer that it does not release if it is tugged on or catches on a piece of machinery or moving object. This lack of release can result in injury to the user.
In one aspect, this disclosure describes a clasp that provides for easy adjustment of the bandana as well as for a safe release under sudden or severe tension. The clasp includes two distinct bodies, that may be identical. The two bodies can be comprised of a resilient material that can be deformed by hand. One end of the bandana is threaded through orifices, or passages, in one of the bodies and the opposing end of the bandana is threaded through passages in the other body. The bodies are then connected together by deforming one end of the first body and pushing it through a passage in the second body. Once the deformed end is released, the first body is securely but removably attached to the second, keeping the bandana (or other garment) in place. The tightness of the bandana can be adjusted by further threading the fabric through the passages or by de-threading (backing off) the fabric through these passages. When tension is applied to the garment, the fabric can slip through the passages allowing for the release of the garment from the wearer. In other cases, tension results in deformation of the one or more of the two bodies, allowing the end of the first body to slip through the passage of the second. In instances of extreme tension, either or both of the bodies can tear, releasing the ends of the garment immediately.
In various embodiments, the body can be made from a polymer, paper, cardboard or fabric. Suitable polymers include silicone, EVA, PVC, thermoplastics, PVDF, polyamide and polyurethane. In some embodiments, the polymer can be a non-allergenic polymer such as, for example, EVA or silicone. The body can be made by methods know to those of skill in the art such as by die cutting, extrusion, molding and 3-D printing. The material may be of consistent thickness (less than 5% variation) or can be of variable thickness in different portions. Thicknesses may be, for example, less than 5 mm, less than 3 mm, less than 2 mm or less than 1 mm. In other embodiments, the thickness of the body maybe greater than 0.25 mm, greater than 0.5 mm, greater than 1 mm, greater than two mm or greater than 3 mm. In specific embodiments the thickness range maybe from 0.5 to 5 mm, from 0.5 to 3 mm, from 0.5 to 2 mm, from 1 to 10 mm.
As illustrated in
Also shown in
Although the embodiment shown illustrates three passages, other embodiments may include 2, 3, 4, 5 or more passages. Additional passages may allow for adjustment of the clasp without removing the garment from the individual elongated bodies.
The embodiment shown in
When the wearer desires to remove the bandana, the clasps can be disconnected by passing end portion 110 back through orifice 220 to release the two elongated bodies, or the ends of the bandana can be pulled backwards through passage 224 and 222 or through 124 and 122. When tension is applied to the bandana the tension is transferred to the clasp and may release in one or more of three different ways. In the first manner, such as when a slow steady force is applied, the end of bandana 310 is simply pulled slowly back through the passages in the clasp leaving the two elongated bodies attached together, absent at least one end of the bandana. In a second scenario, enough tension is applied that one or both of end portion 110 and passage 220 are able to deform to an extent where elongated body 100 is pulled through orifice 220 and therefore released from the other elongated body of the clasp. In a third scenario, an intense force is provided, and a sudden extreme tensile force is placed on the system. In this case one or both elongated bodies may fail by separating at a point of weakness such as score line 130. Other points of weakness may include an area of less thickness such as one that may have been heat stamped, or may simply be the narrowest (point of least material in cross section) section of the elongated body. In any case, the wearer can be assured that the bandana will be released from his or her neck should a force from a person, vehicle or machine pull on the bandana in a dangerous manner.
