UNITED STATES PATENTS 2,411,831 11/1946 Lehmberg et a1 2/181 8 Clam, 5 Drawmg F'gures SWEAT BAND FOR A HARD HAT SUSPENSION UNIT This invention relates to a hard hat. and in particular to a removable liner as a comfort aid to the wearer.
The usual hard'hat has an adjustable band to enable the hat to be comfortably fitted. This band is nonahsorbent, usually of plastic. In the winter the band becomes cold, resulting in a feeling of discomfort where it contacts the forehead. In the summer, the same part in contact with the forehead becomes slippery because of perspiration. I
The band is suspended inside the hat by a harness attached to a center crown pad which rests on the top of the head. This pad is also of non-absorbent plastic. having the same discomfort characteristics.
The object of the present invention isto alleviate such. discomfort and specifically to accomplish this by means of a liner of absorbent material configured to fit the band. the liner having opposable tabs faced with pressure sensitive adhering material enabling the liner to be easily detached and rolled up to fit a pocket. This arrangement may be used also to line the crown pad.
IN THE DRAWING FIG. I is a perspective view of a hard hat suspension equipped in accordance with the present invention;
FIG. 2 is a perspective view of the band liner of the present invention;
FIG. 3 is a sectional view on the line 3-3 of FIG. 2;
FIG. 4 is a sectional view similar to FIG. 3. showing a modified form of head band liner; and
FIG. 5 is a perspective view of a crown pad liner.
The structure identified by reference character in FIG. I is a head cradle or suspension positionable inside a hard hat. The suspension I0 comprises a plastic band ll, adjustable in nature to comfortably encircle the head. A plurality of integral spikes 12 extend upwardly from the upper edge of the band 11 and these serve to anchor a harness comprising a plurality of adjustable straps 13 which support a crown pad I4 resting on the top of the wearers head.
The normal head band 11 and the crown pad as well are non-absorbent and result in considerable discomfort in hot weather and cold weather as well. Thus the non-porous plastic or other synthetic material of which the band 11 and pad I4 are composed do not absorb perspiration nor is the material a good heat conductor. Under and in accordance with the present invention discomfort to the wearer is alleviated by affording an absorbent liner strip adapted to be removably attached to the band I] at least in the portion which gir dles the brow of the wearer. approximately 180 from one temple to the other. The liner 20 can be easily detached and rolled to fit a pocket when not in use. as at the end of the days work. or discarded or washed for re-use.
Details of the liner are shown in FIGS. 2 and 3. The liner is composed of an absorbent cloth material or wet-strength cellulosics. preferably folded and reverse folded at F1 and F2 so as to present along one edge a one-ply flap 22 and an opposed one-ply flap 23. The folds are secured by stitches S1 and S2.
The flap 23 in its original entirety is identified by phantom line in FIG. 2, because a great deal of the material in rectangular patches is subsequently slit and removed. thereby to afford a plurality of rectangular tabs 24 at what constitutes one edge of the liner 20.
The other flap 22 is slit at intervals. slits SL. Resultantly. there are a plurality offlap extensions. 25. 26, 27. 28 and 29 in spaced relation along the corresponding edge of the liner 20. v
The extensions as -29 are provided with pressure actuatable adhering elements 30. FIG. 3. The adhering elements may be hooked fabric such as the VELTROL brand or they may be a pressure actuatable adhesive. easily separated when pressed against like. material as in the instance of the VELTROL type pressure actuatable fastener.
In like manner. the opposable tabs 24, opposable to the extensions as 25 as hereinafter described. are faced at the free ends thereof with pressure actuatable fastener elements '31. There are at least two tabs 24 for each of the end extensions 25 and'29 and in this con' nection itwill be observed in FIG. 3 that the fastener elements 30 are on.one side of the extensions as 25 while the opposable fastener elements 31 on the tabs 24 are on the opposite side.
The extensions 25 29 are to be folded upwardly around the lower edge of the band I]; the tabs 24 are folded down. FIG. I. and the adhering elements are engaged on the outside of the band I I. In use the band 20 representing a multiple ply absorbent liner to bear against the wearer's brow or forehead is positioned on the inside of the head band 11 as shown in FIG. I with the medial extension 27 located between and below the two spikes 12-1 and I2-2 which identify the forehead portion of the band II. The extensions as 25 are then folded up over the lower edge of the band I I. and the opposable tabs 24 are then folded downwardly to bring the adhering elements 30 and 3| into mating relation. pressing the two together.
It is sufficient to afford two tabs 24 to anchor the end extensions 25 and 29; one tab 24 suffices for the others. The slits SL enable the liner to conform to both the band I I and the forehead; the liner will not roll or slip around the head.
The invention may be embodied as well in an unfolded. single ply absorbent liner 35. FIG. 4. which is otherwise identical in configuration to the liner 20.
Especially for winter wear. and to ease the harness contact a protective liner 40. FIG. 5. of like absorbent material may be located at the underside of the crown pad. the liner 40 having two attaching tabs 42 provided at the free ends with opposable pressure actuatable fastener elements 43 matable at the top of the pad as shown in FIG. 5.
The present invention. at little cost. affords more comfort to the person wearing a hard hat; the liner is easily applied and just as easily detached. and can be folded when not in use. washed or even discarded.
