Description

FIELD OF THE INVENTION

The present invention relates generally to adjustable headbands and, particularly, to adjustable headbands for use in headgear, including, for example, personal protective products such as protective helmets, faceshields and welding shields.

BACKGROUND OF THE INVENTION

Most types of protective helmets worn by workers to protect them from falling objects have a suspension system. The suspension system or headgear support, along with the helmet shell, act to absorb the shock of a falling object striking the top of the worker's head. The suspension system also serves as a support that holds the helmet or faceshield on the worker's head.

The suspension is often a web-like support system comprising two or more strips of material that are arranged to cross each other. The ends of the strips are, for example, attached at four or more points around the circumference of the helmet. A headband is then typically attached to the four or more points of the suspension to permit the helmet to be worn by the worker. To securely position the helmet on the worker's head, it is essential that the circumference of the headband be adjustable to fit the appropriate head size. An adjustable napestrap is often attached at one end of the headband to achieve these results. Such a suspension system is available from Mine Safety Appliances Company of Pittsburgh, Pa. under the trademark STAZ-ON® and is described in U.S. Pat. No. 5,896,586.

U.S. Pat. No. 3,500,474, the disclosure of which is incorporated herein by reference, discloses a headband wherein the napestrap position of the headband is manually adjusted by the wearer to fit the appropriate head size. The two ends of the headband are connected and held in place by a slot-and-projection arrangement. One end of the headband is formed with parallel rows of projections or flanges. The other end of the headband is formed with parallel rows of slots. The size of the headband can be adjusted by inserting the projections of one end of the strap into the slots formed in the other end of the strap at the desired length. While this type of headband is relatively simple to manufacture (in part because separate mechanical fasteners or adjustment mechanisms are generally not required), users of such bands often have difficulty adjusting the band size while wearing the suspension. This inconvenience often results in the use of a different, more expensive type of suspension, such as a ratchet-type suspension system as, for example, described in U.S. Pat. No. 4,942,628.

U.S. Pat. No. 5,896,586, the disclosure of which is incorporated herein by reference, discloses a headband that is relatively simple to manufacture, while providing a fastening mechanism that is relatively easy to adjust. This headband can be fabricated from an integral or monolithic piece of polymeric material. The headband includes a first end and a second end which overlap. The first end includes a plurality of longitudinally spaced attachment members (for example, depressions, recesses or slots). The second end includes a resilient fastener having an opening or a channel to slidably receive the first end in overlapping engagement with the second end. The fastener also includes a fastener surface having at least one cooperating attachment member to cooperate with the attachment members of the first end of the band. The fastener surface is resiliently bowable in a direction away from the first end upon application of a compressive force to the fastener. Upon application of such compressive force, the attachment member of the first end of the band and the cooperating attachment member of the fastener disconnect so that the first end can be slid relative to the fastener (and thereby the second end). Unfortunately, it can be difficult to operate the bowable fastening mechanism of U.S. Pat. No. 5,896,586 with only one hand.

U.S. Pat. No. 6,341,382 also discloses a one-piece adjustable headband which is constructed of lightweight material such as a plastic. The strap is constructed with an integral adjustment or fastening mechanism to adjust the fit of the strap around the head of wearer, purportedly using a single hand. The headband includes a first end, a second end, an interior surface, and an exterior surface. A plurality of ratchet teeth extend from the exterior surface of the headband adjacent the first end thereof. Each of the ratchet teeth has a tapered surface and a locking surface. A clasp is resiliently connected to the exterior surface of the headband adjacent the second end thereof. The clasp includes a pawl which is biased in a locking position wherein the pawl is engageable with the locking surface of one of the ratchet teeth to hold the headband in a selected loop configuration. The clasp is movable to a release position upon application of a force generally normal to the plane of the headband whereby the pawl is moved away from the ratchet teeth to permit the loop configuration of the headband to be increased in size.

Although a number of fastening or adjusting mechanisms have been developed for headbands or head straps for use in headgear, and especially in personal protective equipment such as protective helmets, faceshields and welding shields having a headgear support, it remains desirable to develop improved headbands and adjusting mechanism for use therein, and preferably ones which can be adjusted using only one hand, and more preferably which can also be adjusted with one hand while a user is wearing the protective headgear support.

SUMMARY OF THE INVENTION

In one aspect, the present invention provides a headband for use in a headgear support including a first end section having a plurality of spaced connectors and a second end section including a fastener attached adjacent the end thereof. The fastener includes a connecting member to which at least one cooperating connector is attached. The connecting member biases the cooperating connector in an engagement position with at least one of the plurality of connectors of the first end section to hold the headband in a selected loop configuration. The fastener further includes at least a first flexible release member. Upon application of a force to the first release member, the first flexible release member is movable to a release position (or range of positions) in which the first release member abuts the connecting member to cause the connecting member to flex to a disengage position (or range of positions) in which the cooperating connector is disengaged from the at least one of the plurality of connectors of the first end section to enable increasing the size of the loop of the headband.

In one embodiment, the plurality of connectors on the first end section are slots. The at least one cooperating connector can, for example, be a projection. More than one projection can attached to the connecting member. In another embodiment, each of the projections includes a first surface which is angled to facilitate sliding of the projections over the slots of the first end section when the first end section and the second end section are moved relative to each other to decrease the size of the loop of the headband. In this embodiment, each of the projections also includes a second surface that is angled to abut one of the slots of the first end section when in the engagement position and to provide resistance to movement of first end section and second end section relative to each other in a direction to increase the size of the loop of the headband when in the engagement position.

A generally lateral force can, for example, be applied to the first release member to place the first release member in the release position. The first release member can, for example, include a sloped surface which abuts the connecting member. The headband can further include a second release member that is movable to a release position upon application of a force to the second release member in which the second release member abuts the connecting member to cause the connecting member to flex to the disengage position. In one embodiment, the first release member is positioned on one lateral side of the fastener, and the second release member is positioned on the other side of the fastener.

In another aspect, the present invention provides a headband for use in a headgear support including a first end section having a plurality of spaced slots and a second end section including a fastener attached adjacent the end thereof. The fastener includes a flexible connecting member and at least one cooperating connector attached to the connecting member and biased by the connecting member in an engagement position with at least one of the plurality of slots of the first end section to hold the headband in a selected loop configuration. The connecting member is movable to a disengage position upon application of a generally lateral force to the fastener to cause the cooperating connector to disengage from the at least one of the plurality of slots of the first end section to enable increasing the size of the loop of the headband.

The at least one cooperating connector can, for example, be a projection. As described above, the projection can include a first surface which is angled to facilitate sliding of the projections over the slots of the first end section when the first end section and the second end section are moved relative to each other to decrease the size of the loop of the headband. In this embodiment, the projection can further include a second surface that is angled to abut one of the slots of the first end section when in the engagement position and to provide resistance to movement of first end section and second end section relative to each other in a direction to increase the size of the loop of the headband when in the engagement position.

The headband can further include at least a first flexible release member which is movable to a release position upon application of a generally lateral force thereto. In the release position, the first release member abuts the connecting member to cause the connecting member to flex to the disengage position. In one embodiment, the headband further includes a second release member which is movable to a release position upon application of a generally lateral force to the second release member. In the release position thereof, the second release member abuts the connecting member to cause the connecting member to flex to the disengage position. The first release member can, for example, be positioned on one lateral side of the fastener, and the second release member can be positioned on the other side of the fastener.

In one embodiment, a generally lateral force is applied directly to the connecting member to cause the connecting member to move to the disengage position.

In still a further aspect, the present invention provides a headband for use in a headgear support including a first end section having a plurality of spaced slots and a second end section including a fastener attached adjacent the end thereof.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 illustrates an embodiment of a headband or head strap 110 of the present invention for use in a headgear support. Headband 110 is, for example, a flexible member that can be molded from one or more suitable polymeric materials to extend around the head of the user. Headband 110 can, for example, be formed from an integral or monolithic piece of polymeric material or can, for example, be co-molded or otherwise fabricated from two or more polymeric materials. A first end 120 and second end 160 overlap, preferably at the back of the wearer's head (see, for example, FIGS. 4A and 4B). Headband 110 may be straight from end to end, in which case first end 120 and second end 160 will overlap on the head of the user. On the other hand, first end 120 and second end 160 may extend downwardly in the rear portion of headband 110 across the nape of the neck. The latter embodiment is illustrated in FIGS. 1 through 5. Regardless of which type of headband 110 is used, overlapping ends 120 and 160 are connected in the same manner.

First end 120 includes a connection mechanism 125 that, in the embodiment of FIGS. 1 through 5, comprises a plurality of longitudinally spaced connective elements such as spaced slots 130. Second end 160 includes a cooperating fastener 170 which includes at least one cooperating connective element that forms an operative connection with at least one of the spaced connective elements of connection mechanism 125 to form an adjustable overlapping connection between first end 120 and second end 160. In FIG. 1, arrow A1 represents a generally latitudinal direction as such term is used herein, whereas arrow A2 represents a generally longitudinal direction as such term is used herein.

First end 120 is maintained in slidable connection with fastener 170 and second end 160 via retaining members 172 (see, for example, FIG. 4B) on an interior side thereof (that is, the side closest to the wearer's head while donned) of fastener 170. Each of retaining member 172 also includes a projecting flange or ridge 172a which abuts the sides of first end section 120 when first end section 120 is in operative connection with second end section 160. First end section 120 passes through an opening or notch 174 formed in fastener 170. Retaining members 172 and opening 174 form a channel through which first end section 120 is slidable to adjust the loop formed by headband 110 (see, for example, FIGS. 4A and 5 for an example of the loop configuration). Opening 174 includes recesses 174a through which ridges 122 formed on the lateral sides of first end section 120 pass. Ridges 122 can, for example, add strength or stiffness to first end section 120.

Fastener 170, for example, includes a flexible connecting member or arm 180 having at least one cooperating abutment member or tooth 178 (see, for example, FIGS. 2B and 4C) attached thereto. Each of abutment members 178 extends into one of slots 130 (see, for example, FIG. 4C) to form an operative connection between first end section 120 and second end section 160.

In the embodiment of FIGS. 1 through 5, abutment members 178 are in the form of projections or flanges and include a first surface 178a (see FIGS. 4C and 4D) that is sloped to facilitate sliding of first end 120 through fastener 170 to reduce the size of headband 110 (thereby tightening the fit thereof). For example, application of an appropriate force to first end 120 (and/or second end 160) to tighten headband 110 causes sloped surfaces 178a of projections 178 to “slide over” or past slots 130. Projections 178 further include a second surface 178b (see FIGS. 4C and 4D) that is generally vertical. Surfaces 178b, in cooperative connection with slots 130, provide substantial resistance to movement of first end 120 away from second end 160 (which would result in loosening of the fit of headband 110). In that regard, loosening of the fit of headband 170 typically requires placement of flexible connecting member 180 into a release or bowed state as illustrated in FIG. 4D to move projections 178 out of operative abutting connection with slots 130.

In the embodiment of FIGS. 1 through 5, fastener 170 includes a first end 170a and a second end 170b. Connecting member 180 is attached at a first end thereof to first end 170a of fastener 170 and at a second end thereof to second end 170b of fastener 170. Flexible connecting member 180 includes a raised section 180a generally in the center thereof. Fastener 170 further includes first and second (or upper and lower, in the orientation of, for example, FIG. 4A) flexible release members 184a and 184b, respectively, on each lateral side thereof. First and second flexible release members 184a and 184b are attached at a first end thereof to first end 170a of fastener 170 and at a second end thereof to second end 170b of fastener 170 and can flex about those points of attachment.

To place connecting member 180 in its bowed or release position or state as illustrated in FIG. 4D, the wearer of headband 110 reaches behind the wearer's head and applies (for example, with a single hand) a generally latitudinal compressing force F (see FIG. 4B) to each of flexible release member 184a and 184b. For example, the wearer can place the wearer's thumb on lower release member 184a and the wearer's index finger on the upper release member 184b and squeeze upper and lower release member 184a and 184b toward each other. Each of flexible release members 184a and 184b includes a sloped abutment member 186a and 186b (see, for example, FIGS. 3B and 4B), respectively, in operative connection therewith. As release members 184a and 184b, and thereby sloped abutment members 186a and 186b, are forced toward each other, abutment of sloped abutment members 186a and 186b with raised section 180a of connecting member 180 forces connecting member 180 into its release state as illustrated in FIG. 4D. As abutment members 186a and 186b are forced toward each other, inward projecting contact members 188a and 188b on an inner side of abutment members 186a and 186b contact and slide along the outer surface of first section 120, thereby reducing or eliminating bending of abutment member 186a and 186b relative to connecting member 180. Rearward motion of first section 120 relative to fastener 170 and connecting member 180 is prevented by contact of the inner surface of first section 120 with retaining members 172. In the release state or position of connecting member 180, projections 178 are out of contact with slots 130, and first section 120 can be moved relative to second section 160 and fastener 170. When compressive force as described above is removed from release members 184a and 184b, release members 184a and 184b (and abutment members 186a and 186b) return to their unstressed or locking state as illustrated in FIGS. 4B and 4C, allowing connecting member 180 to return to its locking or connecting state as illustrated in FIG. 4C. Even in its locking state, connecting member 180 can be flexed and not fully relaxed so that it biases projections 178 in operative connection with slots 130 of first end 120.

Actuation of release members 184a and 184b is typically required only to loosen or enlarge headband 110. In that regard, projections 178 provide little resistance to motion of first end section 110 relative to second end section 160 and fastener 170 in a tightening direction. To tighten the fit of headband 110, the user can readily reach behind his or her head, place the user's fingers in contact with tab 150 on first end 120 and with tab 190 on fastener 170, and force tabs 150 and 190 toward each other to tighten the fit of headband 110.

As illustrated, for example, in FIG. 4A, second end section 160 also includes an extending member 188 extending from second end 170b of fastener 170. Extending member 188 contacts first end section 120 and assists in maintaining that portion of first end section 120 that projects through fastener 170 in close proximity to second end section 160.

As described above, all components of fastener 170 can, for example, be fabricated as a monolithic unit (via, for example, molding) from a resilient polymeric material wherein connecting member 180 flexes about its attachment points with first end 170a and second end 170b of fastener 170 and release member 184a and 184b flex about their attachment points with first end 170a and second end 170b of fastener 170. Likewise the entirety of headband 110 can be fabricated as a monolithic unit from a resilient polymeric material. Alternatively, one or more components of headband 110 can be fabricated from different materials via, for example, a co-molding process as known in the art. One or more components of headband 110 can alternatively be fabricated separately and later assembled to form headband 110. Resilient polymeric materials suitable for use in the present invention include, but are not limited to, polypropylene, high density polyethylene and/or nylon.

FIGS. 6A through 6E illustrate another embodiment of a headband 310 of the present invention. Like headband 110, headband 310 includes a first end section 320 and a second end section 360. First end section 320 includes a plurality of slots 334 formed in an upper or outer surface 328 thereof. Second end section 360 includes a fastener 370. Fastener 370 includes tabs or flanges 372 (see FIG. 6E) on a rearward side thereof and an opening 372a through which first end 320 passes to assist in maintaining first end 320 in operative connection with fastener 370 and first end 360. Fastener 370 includes a cantilevered connecting member or arm 384 including a downward oriented abutment member such as a projection 386 on an end thereof. Projection 386 operatively cooperates with slots 334 to adjust the fit of headband 310. Projection 386 can, for example, include a sloped surface 386a proximal to or facing first end 320 (which causes little resistance to tightening of headband 310) and a generally vertical surface 386b (which provides substantial resistance to loosening of headband 310).

Fastener 370 further includes a single release member in the form of a lever arm 374 including a beveled or sloped surface 374a which is adapted to contact a lower edge 388 of flexible connecting member 384. Application of force to finger contact 378 of release member 374 (as illustrated in FIGS. 6C and 6E) causes release member 374 to move or flex latitudinally upward (in the orientation of FIG. 6D). Sloped surface 374a of release member 374 forces cantilevered connecting member 384 to swing outward, away from first end 320, thereby removing projection 386 from operative connection with slots 334 (see, for example, FIG. 6E). A finger contact 380 (see FIG. 6C) opposite to finger contact 378 can be provided to facilitate operation of release member 374. Tabs 350 and 390 can be used in the manner described above in connection with tabs 150 and 190 of headband 110 to facilitate tightening of headband 310. Use of tabs 350 and 390 to tighten headband 310 is illustrated in FIG. 6B.

FIGS. 7A through 7E illustrate another embodiment of a headband 410 of the present invention in which a first end 420 includes a plurality of slots 434 formed in an outer surface thereof. Second end 460 includes a fastener 470 In this embodiment, fastener 470 includes a flexible connecting member in the form of a lever arm 484 including an abutment member such as a projection 486 which forms an operative connection with one of slots 434 to control the fit of headband 410. In the embodiment of FIGS. 7A through 7E, force is applied by the wearer directly to an outward projecting flange or tab 484a of connecting member 484 to place release member 484 in a release state. In that regard, a generally lateral force can be applied to release member 484 as illustrated in FIGS. 7C and 7E to cause release member 484 to swing outward as illustrated in FIG. 7E to remove projection 486 from operative connection with slots 434 to enable loosening of headband 410. Projection 486 can, for example, include a sloped surface and a generally vertical surface as described above to provide little resistance to tightening the fit of headband 410 while providing substantial resistance to loosening of the fit of headband 410. Tabs 450 and 490 can be used in the manner described above to facilitate tightening of headband 410 as illustrated in FIG. 7B.
