HEfiZ/G & JESSU ATTORNEYS"- United States Patent 3,026,526 BATI-IING CAP Arthur Montrose, 2058 W. 99th St., Los Angeles, Calif. Filed Jan. 19, 1959, Ser. No. 787,657 4 Claims. (Cl. 2-68) This invention relates to a bathing cap, and more particularly to a water-tight bathing cap which is inflatable by the wearer, during use thereof, for effecting a water-tight seal around the lower marginal edge thereof.
Bathing caps are widely used by divers and swimmers to avoid wetting of the hair during such activity and in many cases to keep water out of a persons ears which are frequently sensitive to water and water pressures. Women particularly use bathing caps during swimming and diving activities to protect their hair and/or-hair-do which would otherwise become disheveled. However, bathing caps in general are not entirely water tight around the peripheral edge, with the result that an injurious amount of water seeps under the marginal edge of the bathing cap. Particularly during diving, the water is forced into the bathing cap, thereby rendering the bathing cap useless as to its purpose.
Entrance of water into the bathing cap during use is due partly to the design of the bathing cap, which, in order to be stylish, does not provide an efficient Sealing edge, and partly due to the fact that a human head is irregular in shape, the forehead being the only portion that can be sealed inasmuch as the forehead is, in most persons, arcuate and forms a tight contact with the forehead portion of the bathing cap. On the other hand, the temple portion, joining the cheeks, and the nape portion of the neck form irregular surfaces which are diflicult to seal. A bathing cap made of elastic material such as rubber, neoprene or the like, is stretched in the application over the head, whereby the hollows and ridges of the human head adjacent the marginal edge of the cap form gaps through which water may enter into the cap and defeat the purpose of the cap.
It is therefore an object of this invention to provide a new and improved bathing cap of elastic, resilient material which is provide-d with a marginal edge adapted to effect a water-tight seal relative to the users head.
It is a more specific object of this invention to provide a bathing cap having an inflatable marginal edge to form a tighter and more eflicient seal relative to a persons head and particularly to follow the irregularities of a human head.
It is another object of this invention to provide a new and improved bathing cap of the character described which is easily and quickly inflatable by the user after the cap has been placed over the head whereby the inflatable marginal edge is conformable to the configuration of the users head.
Still another object of this invention is to incorporate the inflation means into a chin strap which provides an additional purpose of retaining the bathing cap on the users head and fastening means for fastening the chin strap to the bathing cap.
Still another object of this invention is to provide valve means incorporated in the inflation means whereby the user may quickly and easily close the inflation means for the inflatable marginal edge to retain pneumatic pressure within the marginal edge and which can be quickly and easily opened to release the pressure.
Yet another object of this invention is to provide a new and improved water-tight bathing cap which is economical to manufacture and capable of mass production.
A general object of this invention is to provide a new and improved bathing cap of the character described which overcomes disadvantages of prior means and methods heretofore intended to accomplish generally similar purposes.
This invention provides a bathing cap of a pliant, resilient material having a substantially hemispherical hollow cap whose marginal edge defines an opening for insertion of the head of the user within the cap, the marginal edge being expandable and inflatable to more nearly follow the configuration of the users head, and a chin strap integral with or attached to one side of the cap and having a passage extending therethrough and communicating with the inflatable edge. A valve means is incorporated for manually, selectively closing the passage from the inflatable marginal edge, thereby selectively captivating the air within the inflatable marginal edge and releasing the air therefrom, whereby the user of the cap may, by any suitable means, introduce air into the passage of the chin strap for inflating the marginal edge to effect a watertight seal of the marginal seal relative to the users head.
These and other objects of this invention will be more apparent from the drawings, detailed description and appended claims.

Referring more particularly to the drawings, there is shown by way of illustration, but not of limitation, a bathing cap, generally referred to by thenumeral 10, designed and constructed in accordance with this invention. Thebathing cap 10 comprises a substantially hemisphericalhollow cap body 11 of a relatively thin, pliant, resilient material, such as rubber, neoprene, plastics, or the like. Thecap body 11 is herein illustrated as having a rather conventional style and configuration whosemarginal edge 12 includes aforehead portion 13, adjacent co-extensivetemple portions 14 and downwardly extendingneck portion 16 which depends sufliciently to cover the ears and the nape for the neck of the wearer thereby completely enclosing the hair of the wearer which, in the case of long hair, is normally tucked under and within thebody 11.
In order to provide a sealing engagement between themarginal edge 12 and the outer surface of the head, illustrated inbroken lines 17, a substantial portion of themarginal edge 12 is provided with an inflatable tube means 18 which may be integral with themarginal edge 12 of thebody 11 or may comprise, as herein illustrated, a discrete strip of pliant resilient material, such as rubber, neoprene, plastics, or the like, cemented or otherwise secured to theinner surface 19 of thebody 11. In the preferred embodiment illustrated herein, the tube means 18 comprises an extruded, or otherwise formed, strip having substantially parallel, flat,outer edges 21 cemented or otherwise secured to thebody 11, a pair of spaced parallel outwardly extending (extending inwardly of the cap) doubled-back ridges 22 and anintermediate wall section 23 defining acavity 24 between the tube means 18ice 3 and thebody 11 and following the contour of themarginal edge 12.
The tube means 18 may optionally extend completely around the inner periphery of themarginal edge 12 or may, as illustrated, terminate adjacent theforehead portion 13 as indicated at 26 and extend downwardly across thetemple portions 14 and theneck portion 16.
In practice it has been found that theforehead portion 13 of a bathing cap forms an adequately tight fit against the forehead of the user inasmuch as the forehead is substantially convexly shaped. The temples of the head, however, are generally slightly concave, whereby a cap stretched over the temple portion forms a passageway through which water may enter into the interior of the cap. Likewise, the nape of the neck is formed with ridges and hollows, thereby forming passages or gaps through which water may enter the interior of the cap. By inflating the tube means 18, theridges 22 are extended into contact with the contours of thehead 17, thereby filling in the depressions and hollows, particularly at the temple portion, the neck portion and additionally around the jaw portion which is also irregular in contour.
Astrip 27 of pliant resilient material, such as sponge rubber, neoprene, or the like, is preferably disposed within achannel 25 formed by thewall 23 and theridges 22, thestrip 27 being provided with a plurality oflongitudinal ridges 28 andgrooves 29, whereby expansion of thewall 23 forces the relatively soft andspongy strip 27 into intimate contact with the contour of the head to additionally seal themarginal edge 12 around the head. Thestrip 27 is preferably continuous and endless whereby theforehead portion 13 is additionally sealed by the strip, and may be cemented or otherwise secured in thechannel 25 and on theinner surface 19 of thebody 11 at theforehead portion 13.
Thetemple portions 14 of themarginal edge 12 actually extend outwardly of the line of tension when thecap body 11 is being worn whereby inflation at these areas may tend to bulge thebody 11, causing an undesired exaggerated outer appearance. To avoid this, a reinforcing strip orbacking 31 is preferably interposed between thebody 11 and the tube means 18, whereby expansion is achieved primarily in the tube means 18 and resulting in a smoother, non-bulging outer appearance of thebody 11. Thestrip 31 is preferably formed of a material less elastic than thebody 11, such as fabric, plastic, or any other suitable material. As best seen in FIG. 3, thestrip 31 extends from points intermediate of the forehead and temple portions indicated at 32 to points adjacent theneck portion 16 and indicated at 33.
Additionally, to prevent excessive bulging of thebody 11, the thickness of the strip material of the tube means 18 is formed substantially thinner than the thickness of thebody 11 whereby expansion is effected primarily in the walls of the tube means 18. Thepeaks 20 of theridges 22 are further reduced in thickness thereby resulting in weakened or more pliant peaks to eifect greater elasticity and flexibility of the tube means at the peaks of the ridges to conform to the contour of the head.
This invention provides unique means for inflating the tube means 18 in the form of a hollow chin strap means, generally indicated by thenumeral 34. Thechin strap 34 may be integrally formed with thebody 11, as illustrated in FIGS. 1-3 and 5, or optionally separately formed and secured to thebody 11 as by cementing or the like. Thechin 34 is tubular and includes apassage 36 extending therethrough and communicating with thecavity 24 of the tube means 18 in thearea 37 of junction of thechin strap 34 with thebody 11. Thechin strap 34 is open at itsopposite end 38 whereby the user may inflate the tube means 18 after thebody 11 is installed on the head by blowing into theend 38 of the chin strap.
In order to captivate the air within the tube means 18 and prevent deflation thereof, a valve means 39 (see PIG. is provided at thejunction 37 of thechin strap 34 with thebody 11 and spaced inwardly from themarginal edge 12 whereby the communication between thepassage 36 of thechin strap 34 and thecavity 24 may be selectively closed or open. Thevalve 39 includes astem 41 having aplug 42 complementary to apassage 43 of the valve body 44. A transverse opening 46 communicates between thepassage 43 and thepassage 36 whereby an inward movement of thestem 42 causes theplug 42 to close the passage 46 and thereby close oif thepassage 36 from thecavity 24 to captivate air within thecavity 24.
Outward manually effected movement of thestem 41 causes theplug 42 to open the passage 46 to communicate between thepassage 43 and thepassage 37 to admit air into thecavity 24 to inflate the tube means 18 or permit escape of air therefrom for deflation. Thestem 41 and the body 44 are preferably formed of a plastics material which is relatively resilient whereby theplug 42 is frictionally held within thepassage 43 to retain theplug 42 in a sealing position. It is to be understood however that other materials may be used and thestem 41 adapted to retain theplug 42 in its open or closed position as by complementary threads on the stem and in the body 44, if desired.
In order to retain thecap 10 on the users head 17, the chin strap is preferably securable at itsfree end 38 to an opposing portion of thebody 11 as indicated at 47. For this purpose, an adjustable fastening means or slide, generally indicated by the numeral 48 and best seen in FIG. 7, is slidingly disposed on theend 38 which comprises a substantially rectangular body 49 having an opening 51 therethrough for receiving thechin strap 34. The body 49 includes a pair oftransverse end members 52 having archedcentral portions 53 which bridge the central portion of thechin strap 34, and an intermediatetransverse member 54 having an oppositely arched portion 56 and having secured thereto one member of a malefemale snap 57, such as themale portion 58.
The fastening means 48 is slidably disposed on thechin strap 34 with oppositely facingpressure points 59 and 61 of thetransverse members 52 and 54 respectively bearing against oppositeparallel edges 62 of thechin strap 34 to frictionally engage thechin strap 34, the chin strap ex tending into the opening 51 and bridging over the intermediatetransverse member 54, as best seen in FIG. 7. The oppositelyarched portions 53 and 57 of thetransverse members 52 and 54 respectively permit passage of air through thechin strap 34 without removal of the fastening members 48. The body 49 may be secured to thebody 11 by snapping themale member 58 of the fastening means 57 into a complementary female member 63 secured to thebody portion 11. In this manner, thepassage 36 extending through thechin strap 34 is constantly accessible and clear for inflation or deflation of the tube means 18, the communication between thepassage 36 and thecavity 24 being controlled by the valve means 39 for selectively opening and closing thereof.
As will now be more clearly understood, after the user has placed thebathing cap 10 on the head, thestem 41 is pulled outwardly, or screwed outwardly if a threaded stem and body is used, to open the passage 46 and effect communication between thepassage 36 of thechin strap 34 with thepassage 43 of thevalve 39 and thereby thecavity 24 of the tube means 18. The user may then inflate the tube means 18 by blowing into theopen end 38 of the chin strap, or optionally by mechanical means such as an air pump or the like, to cause theridges 22 of the tube means 18 and theridges 28 of thestrip 27 to come into intimate contact with the contour of the users head, filling in any hollows or irregular portions of the contour, thereby effecting a water-tight seal around themarginal edge 12 of thebody 11. It is to be understood that hydraulic pressure may be used to expand the tube means if desired. Thestem 41 may be then pushed inwardly to close communication between the opening 46 and thepassage 43 to captivate the pneumatic pressure within thecavity 24 to retain a sealing Water-tight engagement between themarginal edge 12 and the contour of the head. Thechin strap 34 may be then secured at itsfree end 38 to thebody 11 as by the fastening means 57 after adjusting the body 49 of the slide 48 to provide a comfortable yet adequate retaining force on thebody 11 to retain the cap on thehead 17.
