BUOYANT BATHING SUIT Filed May 2, 1962 3 Sheets-Sheet 3 IN VEN TOR.

United States Patent 3,134,994 BUOYANT BATHING SUIT Agnes W. Christotferson, Honolulu, Hawaii, assignor to Lovie E. Lerner, Edwardshurg, Mich. Filed May 2, 1962, Ser. No. 191,823 Claims. (Cl. 9-334) This invention relates to improvements in buoyant bathing suits, and more particularly to bathing suits of the type shown in Patent No. 2,897,821, dated August 4, 1959, and in the patent application of Lovie E. Lerner, Ser. No. 65,520, filed October 27, 1960, now Patent No. 3,094,722.

The primary object of this invention is to provide a novel construction of buoyant bathing garment having a buoyant shell portion formed of unicellular sheet material of greater thickness than fabric, and a fabric decorative sheath, which garment is so constructed as to provide buoyancy to float a wearer in water and to avoid the appearance of bulkiness when worn.

A further object is to providea garment with a buoyant shell having portions of different thickness and novel shape united to provide a unit of a shape conforming to body contour, particularly at breast portions thereof.

A further object is to provide a garment of this character with a buoyant body-conforming shell formed of unicellular material and utilizing multiple portions joined together with means to reinforce the same at the joints and at margins to facilitate retention of the desired shape and configuration of the shell when the garment is worn.

A further object is to provide a garment with a pre fabricated shell of unicellular buoyant material formed of multiple parts joined togetherto define a body-con forming contour maintained and reinforced in desired contour by fabric garment liner portions assembled therewith to define a unit which is incorporated within an external decorative fabric sheath anchored to said unit at limited portions only so as to facilitate natural draping of the garment in some sections thereof and to provide an overall attractive appearance of the garment when worn.

Other objects will v be apparent from the following specification.

Referring to the drawing which illustrates the preferred embodiment of the invention, the numeral 20 designates a garment fitting around the torso and upper portions of the legs of the body of a wearer, and including a brassiere portion 22 and shoulder straps 24. It will be understood that the shaped brassiere portion may be replaced by a plain upper garment portion in garments of small sizes designed to be worn by children.

The garment includes a shell of buoyant material and preferably a unicellular material formed of a synthetic resin, such as vinyl type plastic. Materials of this character are available in sheet form in different thicknesses and are characterized by a closed cell construction which imparts buoyancy thereto. Other physical properties of such material include flexibility, normal shape retention and resistance to flexing in more than one direction at one time. The material may also be molded to predetermined size, shape and thickness, if desired, but the use of molded parts in garments of different sizes presents problems of manufacturing economy and high mold costs because of the wide range of sizes and shapes necessary in garments, and particularly those of body-conforming configuration. One type of material particularly well suited for use in bathing garments is produced by the United States Rubber Company under the trademark Ensolite. The unicellular material can be joined by cementing parts thereof and by stitching therethrough. Shaping of the unicellular material can be accomplished by skiving thereof.

One example of such a buoyant garment shell is illustrated in FIGS. 4, 5 and 6. In this shell structure the waist portion of the shell is shown as consisting of a plurality of panels, including a front center panel 26 of pre determined thickness and a contour as best seen in FIG. 4, having curved sides, a V-shaped bottom portion and a V-shaped top portion. A pair of substantially similar front side panel portions 28, preferably narrow and vertically elongated and provided with a contour or shape characterized by curved upper edges and curved vertical edges and are cemented or otherwise united at their vertical edges to the vertical edges of the central .panel 26. Rear side panel portions 30 of selected shape characterized by curved edges are united to the vertical edges of the side panels 28. The panels 39 preferably extend above the level of the upper edges of the adjacent panels 28, as best seen in FIG. 6. Shaping of the various panels to facilitate bending thereof to desired contour may be accommodated by notching said panels and notching the edges of the notched panels as seen at 31 in FIG. 4 in the manner. illustrated in the Lerner patent application, Ser. No. 65,520, filed October 27, 1960, mentioned above. The shell portion defined by the

panels

26, 28 and 30 extends for the major portion of the circumference of the body of the wearer, but the free vertical edges of the rear panels 30 terminate in spaced relation, as seen in FIGS. 5 and 8. In the construction here illustrated as shown in FIG. 8, the

panels

26 and 28 may be of one thickness, and the panels 30 may be of a lesser thickness.

The breast or brassiere portion of the buoyant shell preferably comprises four panels of the shape and con figuration illustrated in FIG. 14. The breast-forming panels include two similar or complementary narrow elongated upper panels 32 and two similar or complementary narrow elongated lower panels 34. ,Each of these panels is characterized by a vertical dimension small compared to the horizontal dimension, and with end edges of limited extent. The upper edges of the upper panels 32 are preferably curved convexly and the lower edges of the upper panels 32 are alsovconvexly curved, with the curvature of the lower edges preferably being greater than the curvature of the upper edges. The lower panels 34 are similarly characterized by short verticaledge portions and convexly curved upper and lower marginal edges, with the upper edges of the lower panels 34 being of greater convexity or curvature than the lower edges. For purposes of convenience, the lower edges of the upper panels 32 are designated 33, and the upper edges of the lower panels 34 are designated 35. The inner edges of the two upper panels 32 and of the two lower panels 34 are either cemented together or the two panels 32 may be formed integrally and the two panels 34 may be integrally formed also. I prefer to form the panels separately, however, and to join them by cementing so as to define joints between the panels 32 and panels 34 which are stabilized by cementing or bonding and thereby provided with lesser extensibility or elasticity than characterizes the unicellular material per se. The

edges

33 and 35 of the

panels

32 and 34 are continuously joined as by cementing thereof along their length, whereby a brassiere portion is formed of pocketed character, as illustrated in FIGS. 3 to 7 and 10.

The breast or brassiere portion is joined to the waist portion by cementing or otherwise securing the lower edges thereof to the upper edges of the

panels

26 and 28, and the end edges thereof to the upper projecting part of the rear panel 30. The buoyant shell may also include strap portions 36 formed of unicellular material and extending upwardly from the breast portion at the location at which the shoulder straps 24 will project from said breast portion in the finished garment.

The buoyant shell constitutes a sub-assembly with which is preferably assembled an inner garment liner to produce a unit as illustrated in FIG. 7. This inner liner includes an inner fabric layer 40 and an outer fabric layer 42, which are secured to the buoyant shell, as at the

panels

26, 28 and 30 thereof, as illustrated in FIG. 8, to preferably fit therearound or around at least part thereof. At the margins of the

shell portions

26, 28 and 30, reinforcing tapes preferably cooperate therewith and with the joints between selected portions of the shell to strengthen the shell. Thus at the free vertical margins of the panels 30, fabric tapes 44 may be provided which are anchored to the shell panels 30 and to the outer fabric 42 by stitching 46. At the lower margins of the

panels

26, 28 and 30, said panels are preferably skived or tapered, as illustrated in FIG. 12, and tapes 48 may be secured or anchored to the skived margins of the panels and to the outer fabric 42 by stitching 50. At the portion of the garment between the lower breast panels 34 and the upper ends of the

body panels

26, 28 and 30, a reinforcement as illustrated in FIGS. 10 and 11 may be employed, the same preferably entailing the extension of the outer fabric 42 to a point in contact with the lower margin of the breast portion of the shell at the outer surface thereof. A reinforcing tape 52 is applied to the inner surface of the shell along the joint between the breast and body portions of the shell and is stitched to the shell at the breast and body portions and to the outer fabric 42 by stitching 54. If desired, the stitching at 50 and 54 and elsewhere, as at 46, may be diagonal stitching, as illustrated in FIGS, 11 and 13. The stitching 54 is preferably sufiiciently tight to somewhat constrict the marginal portions of the panels of the body and breast portions of the garment, as illustrated in FIG. 10. The innerlayer 40 may include portions extending in con- 'tact with the inner surfaces of the breast portion at 41, said portions preferably being free from the tape 52 and the shell of the garment at 55, as illustrated in FIG. 10. The

layers

40 and 42 project below the lower part of the shell and may extend inwardly from the rear edges of the shell, as illustrated in FIG. 7. The lower part provides pant and leg portions 56 with elastic leg ends 58, in cases where the shell is formed as illustrated in FIGS. 4, and 6 to terminate at or adjacent the level of the hips of the wearer.

An outer fabric sheath 60 encloses the sub-assembly illustrated in FIG. 7. The sheath is anchored by stitching to the buoyant shell or the inner liner 40, as illustrated at 62 in FIGS. 1 and 10, along a line following the contour of the bottom of the brassiere portion. A contoured brassiere sheath portion 64 fits snugly around the upper shell buoyant portion in garments having a cupped upper shell portion and is stitched at 66 at its upper margin to the upper margin of the liner portion 41. At its mid portion the sheath preferably has clearance with the mid portion of the body of the shell at

parts

26, 28 and 40 thereof, as best illustrated in FIG. 8. The lower portion of the sheath defines leg portions 68 fitting around the inner leg portions 56.

At its back the sheath preferably includes panels 70 of elasticized material which mount slide fastener units 72 at their vertical free edges and serve to draw the sheath fairly snugly around the buoyant shell. The elasticized material 70 in garments for women preferably terminates spaced above the lower portions of the shell, as best seen in FIG. 2, so that the lower leg portions 68 are not drawn tight thereby but are permitted to hang or drape naturally below the shell portion so as to avoid revealing the outline of the shell portion. It will also be observed that the elasticized material 70 may extend for the major portion of its height substantially to the vertical edges of the rear portions of the shell, as seen in FIGS. 2 and 8. Observe also that the elasticized material is preferably stitched both to the outer sheath at 74 and to the inner sheath 40 at 76, and further that the inner sheath 40, at thepart stitched at 76, is free from the shell panel 30 for a distance at least equal to the Width of the tape 44. It will be understood that the arrangement of elasticized material may be extended to a lower level in garments for small girls and that it may be eliminated in garments for men and boys.

The sheath preferably includes portions which encircle the buoyant shell shoulder parts 36 when such parts 36 are used, so as to define the shoulder straps 24 in conjunction with elasticized strips 78 which are anchored to the rear portion of the garment adjacent the opposite side margins of the top of the inner shell.

The garment is characterized by tight fitting of the sheath brassiere portion 64 with the breast or brassiere portion of the shell by virtue of the stitching at 62 and 66, and also by virtue of stitching at 80 between the side margins of the brassiere portion and the adjacent rear panel portions 30. Thus the contour of the brassiere portion is controlled by the shape of the buoyant shell at the brassiere portion while the remainder of the suit or garment has freedom from the buoyant shell except as it is somewhat constrictively drawn thereagainst at the upper part of the waist portion by the elasticized material 70.

The garment is attractive in appearance, easy to don, effectively camouflages the bulk of the buoyant material of the shell which may be of thicknesses from three-sixteenth of an inch to one-half inch or more. It will be observed that the thickness of the shell may vary at different points thereof. Thus it will be noted that

shell portions

28 and 30 are of diiferent .thicknesses, and that

shell portions

32 and 30 are of different thicknesses, as

v viewed in FIGS. 8 and 9, respectively. The difference in thickness will preferably be such as to concentrate buoyancy at the front of the garment so as to permit the garment to assist in turning a wearer floating in the water, so that flotation will occur face up. It will also be understood that in childrens garments and mens garments fewer anchors of the sheath and liner to the shell are required because style and body conforming shapes are of less importance than in an adult womans garment here shown.

While the preferred embodiment of the invention has been illustrated and described, it will be understood that changes in the construction may be made within the scope of the appended claims Without departing from the spirit of the invention.
