INVENTOR WILLIAM J. DORSEY BY M ATTORNEY Un t d St tes Patent 50 LATEX GIRDLE WITH REINFORCED GARTER TABS WilliamJ. Dorsey, Dover, Del., assignor to International Latex Corporation, Dover, Del., a corporation of Delaware Filed Oct. 22, 1956, Ser. No. 617,293

2 Claims. (Cl. 128-521) This invention relates to a deposited rubber latex girdle of the type having dependent, integral, deposited latex garter tabs which extend from the lower edge at each side of the front and back thereof. More particularly, the invention relates to the reinforcing of the garter tabs with fabric to prevent tearing at the juncture thereof with the body portion of the girdle due to the stresses imposed thereon during use of the girdle.

Attempts to reduce the incidence of garter failure in deposited latex girdles with integral tabs by reinforcing the tabs with fabric embedded in the deposited latex did not achieve the desired result. Although the incidence of failure by tearing of the strap per se was reduced, an undesirably high and inexplicable incidence of failure by tearing in the region where the fabric reinforced girdle joined the body of the girdle was observed.

In accordance with the present invention, it has been .found that tear resistance of the garter tabs at the juncture thereof with the girdle can be materially improved if a knitted textile fabric, either natural or synthetic, is used for the reinforcement and this knitted textile fabric oriented in the tabs in a rather unusual manner relative to the direction of maximum stretch of the knitted fabric. More specifically, the knitted fabric is bias cut and incorporated in the tabs and portions of the body of the girdle adjacent the juncture of the tabs so that the direction of maximum stretch is towards the center portion of the girdle (i.e., is at an angle of between 30 and 60 to the longitudinal axis of the tabs).

It has been found that the knitted fabric when so oriented not only provides a surprising increase in the resistance to tearing of the garter tabs at the juncture thereof with the girdle but also reinforces and reduces the longitudinal stretchability of the garter tabs so as to prevent over-stretching of the garter tabs and failure thereof. At the sametime the orientation of the knitted fabric permits sufiicient stretching of the tabs longitudinally to insure comfort.

Having briefly described the invention a more detailed description is given hereafter by reference to the accompanying drawings herein.

Fig. 1 is a front elevation view of a deposited latex girdle incorporating garter tabs reinforced in accordance with the present inention.

Fig. 2 is an enlarged partial elevation view of the lower portion of the girdle and garter tabs with parts broken away to show the incorporation of the reinforcing fabric in the garter tabs, and

Fig. 3 is a plan view of a piece of knitted textile fabric showing the bias cutting of the reinforcing fabric for the garter tabs shown in Fig. 2.

Referring to Fig. l of the drawings there is shown a deposited latex girdle incorporating four integral garter tabs 11, two in the front and two in the back. For the purpose of illustration a garter 12 is shown attached to one of the tabs 11. When the girdle is in use a garter 12 is, of course, attached to each of the garter tabs 11.

In accordance with the invention, all of the garter tabs 11 are reinforced with strips 13 of knitted textile fabric, such as nylon knitted fabric, which extend substantially coextensive with and are embedded in and adhered to the tabs 11 and extend into and are embedded in the body portion 14 of the girdle adjacent the juncture of the tabs 11 with the body portion 14. Preferably the end portions 13a of the strips 13 which extend into the body portion 14 are enlarged to provide a maximum adhesion area and reduction in stress concentration at the boundary thereof by distributing the load over a large area.

As best shown in Fig. 2, the reinforcing strips 13 are cut from a sheet of knitted textile fabric 15 on a bias of between 30 and 60, preferably about 45. As is well known, a knitted fabric is highly stretchable in one direction and substantially unstretchable in a direction thereto. In Fig. 3, the arrow AA indicates the highly stretchable direction of the fabric 15 and the arrow BB the relatively unstretchable direction of the fabric 15. By cutting the reinforcing strips 13 on a bias of between 30 and 60, it will be evident that the direction of maximum stretch of the strips 13 will be at an angle of between 30 and 60 to the longitudinal axis C-C of the strips 13.

In accordance with the invention, the bias cut strips 13 are incorporated in the tabs 11 so that the direction of the maximum stretch, as indicated by the arrow AA, extends towards the center portion of the girdle at the bias angle of between 30 and 60 to the longitudinal axis C-C.

The reinforcing strips 13 may be conveniently embedded in and adhered to the tabs 11 and body portion 14 during the forming of the girdle in the dipping operation. This is done by first making one or more dips into the latex to deposit one or more layers on the form, by known methods such as those described in US. Patent No. 2,360,- 736, issued October 17, 1944, to A. N. Spanel, then applying the strips 13 in the proper location on the deposited latex on the form, and thereafter making one or more dips in the latex to completely embed the strips in the tabs 11 and body portion 14. Thereafter the girdle is cured by well known methods.

When the garter tabs 13 are reinforced as above described, the incidence of tearing of the tabs 11 at the juncture thereof with the body portion 14 is materially reduced. At the same time, the component of stretch of the fabric strips 13 in the longitudinal direction is suflicient to insure comfort in supporting the stockings of the wearer of the girdle, but is not of a magnitude sufiicient to permit over-stretching.

If desired the thickness of the deposited latex in the areas of the enlarged end portions 13a of the strips 13 and areas immediately surrounding the enlarged end portions 13a may be increased a substantial amount, i.e.,

to one and one half to two times that of the thickness of the major area of the girdle, to thereby provide additional reinforcement in these areas. These areas of increased thickness extend a substantial distance, i.e., or more, beyond the boundaries of the end portions 13a. In Fig. 2, the boundaries of these areas of increased thickness are indicated by the broken lines 16.

While one embodiment of the invention has been described above, it is to be understood that this is for the purpose of illustration only and that changes and modifi cations can be made therein Without departing from the spirit and scope of the invention.

I claim:

1. A deposited latex girdle having dependent integral garter tabs extending from the lower edge of the body portion of the girdle at each side thereof, said garter tabs being reinforced with a knitted textile fabric which is embedded therein and extends into and is embedded in the'body portion of the girdle adjacent the juncture of the'tabs with said body portion, said textile fabric being bias cut and embedded in said tabs and body portion with the direction of maximum stretch thereof oriented towards the center portion of the girdle.

2. A deposited latex garment having laterally spaced dependent integral'tabs extending from the body of the garment, said tabs being reinforced with a knitted textile fabric which is adhered to said tabs and the body portion of the garment adjacent the juncture of the tabs with said body portion, said textile fabric being bias cut and adhered to said tabs and body portion with the direction of maximum stretch thereof oriented towards the center portion of the garment.
