Abstract
Description
- This invention pertains to a multi-purpose headband for a filtering face mask and, in particular, to a multi-purpose headband that may use one or two straps to mount to the face mask.
- Filtering face masks (also referred to in some instances as "respirators") are worn over the breathing passages of a person for two common purposes: (1) to prevent impurities or contaminants from entering the wearer's breathing track; and (2) to protect others from being exposed to pathogens and other contaminants exhaled by the wearer. In the first situation, the respirator is worn in an environment where the air contains particles harmful to the wearer, for example, in an auto body shop. In the second situation, the respirator is worn in an environment where there is a high risk of infection, for example, in an operating room.
- To accomplish either of these purposes, the respirator must be able to maintain a snug fit to the wearer's face. To achieve a snug fit, filtering face masks typically have a headband extending laterally from the mask around the back of the wearer's head and neck. The headbands usually include an elastic strap member that adapts to a range of sizes to provide a comfortable fit. Some masks have a headband that uses a single strap while others use two straps.
- Because there are differences in wearers' preferences and hair styles, some wearers may prefer a single strap while others may prefer dual straps extending around the back of the wearer's head and neck. Masks typically are only manufactured with either one strap or two straps and are not able to accept interchangeably either a single strap or double straps. Uneven tension from a two strap configuration may exert forces that skew the mask from its intended wearing configuration. This can cause leaks around the mask perimeter, creating safety concerns and an incumbent decrease in utility.
- Examples of face masks that accommodate two straps are shown, for example, in U.S. Patent No. 2,353,643 to Bulbulian, U.S. Patent No. 3,220,408 to Silverberg, U.S. Patent No. 5,191,882 to Vogliano, and U.S. Patent No. 5,086,768 to Niemeyer. Although these face masks and respirators accommodate two straps, the devices all require that both straps be attached to the mask body for proper positioning of the mask. None of the patents disclose a mask with a single strap or a system that can accommodate either a single strap or double straps.
- In view of the above, it can be seen then that a new and improved headband system for a face mask is needed. Such a system should provide for mounting either a single strap or double straps to the face mask at a single attachment point to establish a good seal against the wearer's face. The system should also provide for utilizing an essentially identical strap for either the single strap configuration or utilizing two of the same straps in a double strap configuration. And the system should interchangeably mount either the single strap or two straps to the mask. The present invention addresses these, as well as other shortfalls associated with known face mask headbands.
- In a first aspect, the invention provides a headband assembly configured for connecting to a mounting member that is disposed on a mask body of a filtering face mask. The headband assembly comprises a first strap connector for connecting a strap to the mounting member and a second strap connector for connecting two of the straps to the mounting member.
- In a second aspect, the invention provides a face mask headband system that is capable of being attached to a mask body of a filtering face mask where the head band system comprises (a) a single strap device attachable to the mask, and (b) a double-strap device attachable to the mask interchangeably mounting with the first strap device.
- In a third aspect, the present invention provides a face mask that comprises a mask body, a mounting stud located at each side of the mask body, a single headband having end connectors configured for pivotally connecting to the mounting studs, and a double headband assembly configured for mounting to the mask body interchangeably with the single headband. The double headband assembly includes a mask mounting member having a connector for pivotally connecting to the mounting stud. The mask mounting member also includes a mechanism that allows two of the single headbands to be attached thereto.
- In a fourth aspect, the present invention provides a face mask that comprises a mask body and a harness assembly. The harness assembly is configured for pivotally connecting to the mask body. The harness assembly comprises a first strap connector for connecting to a first strap and a second strap connector for connecting to a second strap.
- For a single strap configuration, the strap is inserted through a connector that includes a retainer member receiving one end of the strap. Each connector includes a tongue member with an orifice formed therethrough for mounting onto one of the studs of the mask body. There is a slight interference fit between the widened portion of the stud and the orifice in the tongue so that'the connector snaps onto the stud but is retained by the widened end portion. The connectors provide for adjusting the length of the strap and for fitting various head sizes. In addition, the connectors rotatably mount to the studs, providing for a pivotal connection between the strap and the mask body.
- When a dual strap configuration is used, the same end connectors are utilized. A harness assembly having a mask mounting member, however, is utilized that receives a pair of strap end connectors. In a preferred embodiment, a mounting member includes two end connector receiving portions that extend in a diverging arrangement to one another to provide for a spaced apart mounting configuration between the ends of the dual straps.
- The end connector retaining portions include a recessed base receiving the tongue of the end connector with a pin extending upward from the base. The pin includes an angled upper portion to provide for sliding the tongue into a receiving portion and over the pin. The innermost side of the pin is, however, not angled and retains the tongue once inserted. Sides and a cross bar retain the remainder of the end connector flat against the mask mounting member. The mask mounting member also includes an orifice formed therein similar to the orifice in the end connector for mounting to the studs of the mask body. The mask mounting member pivotally connects to the mask body to provide for a range of adjustment and a more comfortable fit for the wearer.
- The present invention is advantageous in that the same end connectors used with a single strap configuration may also be utilized with a dual strap configuration. In addition, the same stud members on the mask body are utilized, providing for easy mounting and interchanging between a single strap connector or dual strap headband assembly. The face mask and headband assembly of the invention provide for easily interchanging either a single or dual strap configuration using the same elements for reducing the total number of parts required.
- Referring to the drawings, where like reference letters and numerals indicate corresponding structure throughout the several views:
- FIG. 1 shows a front elevational view of a face mask having a double headband assembly mounted at one side of the mask according to the principles of the present invention;
- FIG. 2 shows a partially exploded perspective view of a portion of the mask and double headband shown in FIG. 1; and,
- FIG. 3 shows a perspective view of a single headband mounted to the mask according to the principles of the present invention.
-
- In FIG. 1 there is shown a filtering face mask, generally designated 10, that includes a
mask body 12 having anose brace 16 at an upper portion of the mask body. Themask 10 is generally configured to follow the contour of the wearer's face, and thenose brace 16 is pliable to adapt to the contour of the wearer's nose. At either side of themask body 12 are mounting members shown in the form ofstuds 14 extending outward from the surface of themask body 12. Themounting studs 14 include a cylindrical portion with an upper widened end. Themask body 12 attaches to a headband assembly, generally designated 20. As shown in both FIGS. 1 and 2, twostraps 24 may be utilized to retain themask 10 on the wearer.Straps 24 are attached to afirst strap connector 30 that is capable of connecting to asecond strap connector 50. Or as shown in FIG. 3, theheadband assembly 20 may take on a different configuration where asingle strap 22 is used in the headband assembly such thatconnector 30 attaches thestrap 22 to themounting member 14 on themask body 12 rather than to thesecond strap connector 50. - Referring to FIG. 1, the
second strap connector 50 mounts to themask body 12 on thestud members 14. Theorifice 54 is sized so that it fits onto thestud member 14 with an interference fit over the widened end portion of thestud member 14 similar to the direct mounting of theend connector 30. Once thestud member 14 has been inserted through theorifice 54, the widened end portion retains the base 52 against themask body 12. With this configuration, thebase 52 is free to rotate about thestud 14, and thesecond strap connector 50 is pivotally mounted to themask body 12. When themask 10 uses only asingle strap 22 as shown in FIG. 3, the strap extends between twoend connectors 30, one connecting to eachend 26 of thestrap 22. Theend connector 30 includes atongue portion 32 having a rounded end and an orifice 34 (FIG. 2) formed therethrough. Eachend connector 30 includes astrap receiving portion 36 that has a grippingmember 38. The gripping member includes ahinge 40, shown as a living hinge in the preferred embodiment for reduced cost and ease of manufacture, and a leadingserrated edge 42. The grippingmember 38 pivots between an open position, shown in FIG. 3, for inserting theend 26 of the strap and a closed position, shown in FIG. 1 where thestrap 22 is firmly retained. When the grippingmember 38 is closed, following insertion ofstrap 26 end through the receivingportion 36, the serratedleading edge 42 engages thestrap 22 and secures theconnector member 30 to thestrap 22 at the selected position. - This adjustable retaining system allows the length of the
strap 22 to vary to a size that fits most comfortably around the neck and head of the wearer. As explained below,dual straps 24 also connect to thesame connector members 30. - The
end connectors 30 easily attach to themask body 12 by inserting them onto the mountingstuds 14. Thestud 14 inserts through the orifice 34 (FIG. 2) formed in thetongue 32. The widened end portion of thestud 14 has a slight interference fit with theorifice 34 to enable thestud member 14 to be forced through theorifice 34 so that theconnectors 30 snap onto thestuds 14. Once inserted, however, the widened end portion of thestud member 14 retains thetongue 32 against themask body 12. When theend connector 30 has been attached to themask body 12, theconnector 30 rotates about thestud 14, and a pivotal connection is formed between thestud member 14 and theend connector 30. This configuration provides greater flexibility in adapting the mask to the shape and size of the wearer's head to achieve a more comfortable fit. - In FIG. 2, there is shown an embodiment of the
headband configuration 20 for themask 10 which uses a double band assembly. When double straps 24 are used around the back of the head and neck of the wearer, asecond strap connector 50 is utilized. Thesecond strap connector 50 includes a base 52 that has anorifice 54 formed in the base. Thebase 52 includes twostrap receiving portions 60 extending at substantially right angles to one another with abrace 56 extending therebetween. Thestrap receiving portions 60 are configured for receiving theend connectors 30 and forming a harness assembly connecting to double straps 24. Although this embodiment uses twostraps 24 or a double band harness, a single one of thestraps 24 may be mounted as shown in FIG. 3, for use as asingle strap 22 in a single band harness assembly. Therefore, the interchangability of thestraps same end connectors 30 provides for a more adaptable mask retaining system. - Each of the
strap receiving portions 60 includes a retainingpin 62 extending upward from the base. Thepin 62 includes a slantedface portion 64 angled toward an insertion end of thestrap receiving portion 60 to allowconnector tongue 32 to be easily and readily secured to receivingpotion 60. Near the outward end of thestrap receiving portion 60, aretainer 66 forms a space for receiving thetongue 32 of theend connectors 30. Theretainer 66 includessides 68 and a recessedbase 70. Across member 72 is spaced apart from the recessedbase 70 and is configured for sliding thetongue 32 into thestrap receiving portion 60. When inserted, thetongue 32 extends under thecross member 72 and over the recessedbase 70. Thetongue 32 is flexible enough to bend upward and slide over theangled face 64 of thepin 62 until the retainingpin 62 is in registration with theorifice 34. The resiliency of the flexingtongue 32 springs thetongue 32 back to a substantially planer position with thepin 62 extending through theorifice 34. Thepin 62 and thecross member 72 cooperate to retain theend connector 30 in themask mounting member 50. The substantially right angled diverging configuration of the twostrap receiving portions 60 provides for spacing the ends of thedouble straps 24 apart from one another for a more stable and comfortable fit for the wearer. - Using the invention,
identical straps 22 may be employed with either a double orsingle headband system 20. Themask body 12 does not need to be modified for receiving either a single or double strap. The present invention also provides for aheadband 20 that pivotally mounts to themask body 12 with either a single or double strap configuration. - Although numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and that changes may be made in detail, especially in matters of shape, size and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
