Undershirts and similar sleeveless garments
Abstract
An undershirt or similar sleeveless garment consists of a
single, substantially rectangular piece of two-way stretchable knit
fabric which, at its opposite end portions, defines the front and
back, respectively, of a body portion. The fabric piece has arcuate
cutouts in its opposed side edges between the end portions and a
neck-opening between the arcuate cutouts with the fabric
therebetween defining seamless shoulder strap portions integral
with the front and back body portions. Side seams of longitudinally
stretchable stitching join together the respective side edges of
the front and back body portions so that the cutouts define
armholes above such side seams. The edge portions of the neck
opening and armholes are reverted or folded back and secured to the
adjacent fabric by longitudinally stretchable stitching extending
along such edge portions for finishing off the neck opening and
armholes and also the upper ends of the side seams without
detracting from the stretchability of the garment.

Claims
What is claimed is:
1. A sleeveless garment of the described character consisting of a
single, substantially rectangular piece of two-way stretchable knit
fabric which is more stretchable in the longitudinal direction of
said rectangular fabric piece than in the direction at right angles
thereto, with the opposite end portions of said rectangular fabric
piece defining front and back body portions, respectively, of the
garment, said fabric piece having arcuate elongated cutouts in its
opposed side edges between said end portions and an oval neck
opening centered laterally between said cutouts with the fabric of
said piece between said neck opening and said cutouts defining
seamless shoulder strap portions integral with said front and back
body portions and extending generally in said longitudinal
direction, longitudinally stretchable stitching joining together
the respective side edges of said front and back body portions to
form side seams at the inside of the garment with said cutouts
defining armholes above said side seams, the edge portions of said
neck opening and said armholes being folded back against the
adjacent fabric of said piece at said inside of the garment, and
longitudinally stretchable stitching extending along said folded
back edge portions and securing the latter to said adjacent fabric
against which said edge portions are folded back for finishing off
said neck opening and armholes and the upper ends of said side
seams.
2. A garment according to claim 1, in which the edge portions at
the bottom of said front and back body portions are folded back at
said inside of the garment against the adjacent fabric of said
piece and secured thereto by longitudinally stretchable stitching
extending along the bottom of the garment for finishing off said
bottom of the garment and the lower ends of said side seams.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates generally to garments such as sleeveless
undershirts and the like, and more particularly is directed to
improvements in garments of the described character formed of knit
fabric.
2. Description of the Prior Art
Conventional sleeveless undershirts and like garments are usually
formed of two pieces or blanks of knit fabric which respectively
form the front and back of the garment. Such blanks have central
cutouts in their upper ends to define a neck opening and cutouts in
the upper portions of their side edges to define armholes, with the
fabric remaining between such cutouts forming front and back
shoulder strap portions. In producing a garment from the described
blanks, the respective side edges of the blanks are stitched
together below the armholes to form side seams, and the abutting
ends of the front and back shoulder strap portions are stitched
together to provide seams extending across the tops of the shoulder
straps. The ends of these side seams and shoulder strap seams have
to be tacked or otherwise secured to prevent the unravelling
thereof. In order to finish off the neck opening and armholes,
separately cut bindings or tapes are stitched along the edges of
the neck opening and armholes, respectively. Since the edges and
ends of the bindings or tapes are raw or cut, such edges and ends
have to be folded under prior to the stitching of the bindings or
tapes to the remainder of the garment.
In the mass production of the above garments, the material for the
bindings or tapes and the labor required for the cutting of the
bindings or tapes and for the attachment thereof to the garment are
significant items of cost. Further, at the top of each shoulder
strap of the garment, the laterally extending seam joining the
front and back shoulder strap portions, together with the multiple
thicknesses of the bindings or tapes extending around the neck
opening and the adjacent armhole, produce substantial, relatively
hard or rigid fabric bulges, particularly at the ends of each
lateral shoulder seam, and these bulges are a source of discomfort
to the wearer, especially when a weight is borne by the wearer's
shoulder.
It has been proposed, for example, in U.S. Pat. No. 2,707,284,
issued to me on May 3, 1955, to provide a garment of the described
character which is devoid of seams extending across the tops of its
shoulder straps. However, in this garment, as in the previously
described garment with shoulder seams, the neck opening and
armholes are again finished off by separately cut bindings or tapes
which prevent full realization of low cost mass production.
Although the absence of seams extending across the tops of the
shoulder straps alleviates the discomfort to the wearer, this
problem is not fully overcome as the multiple thicknesses of fabric
where the bindings or tapes are folded under to hide their cut ends
and edges still create fabric bulges. Further, even if the knit
fabric used for the garment is substantially stretchable with a
view to accommodating a single size garment to wearers of various
sizes, or to the growth of an infant or child over an extended
time, the bindings or tapes applied around the neck opening and
armholes considerably restrict the stretching thereof and of the
shoulder straps.
SUMMARY OF THE INVENTION
Accordingly, it is a general object of this invention to provide an
undershirt or similar sleeveless garment which is capable of being
economically mass produced.
More specifically, it is an object of this invention to provide a
garment of the described character in which substantial economies
are realized in finishing-off the neck opening and armholes and the
side seams of the garment.
Another object is to provide a garment, as aforesaid, which affords
increased comfort to the wearer.
Still another object is to provide a garment, as aforesaid, which
is stretchable at its neck opening, armholes and shoulder straps,
as well as at its body-covering portion, so as to accommodate a
single size garment to wearers of various sizes or to the growth of
an infant or child over an extended period of time.
In accordance with an aspect of this invention, an undershirt or
similar sleeveless garment is formed of a single, substantially
rectangular piece of two-way stretchable knit fabric defining the
front and back of the garment body at its opposite end portions and
having arcuate cutouts in its side edges between such end portions
and a neck opening centered between the edge cutouts with the
fabric between the neck opening and edge cutouts defining seamless
shoulder straps, the respective side edges of the front and back of
the garment body are joined together by longitudinally stretchable
stitching forming side seams of the garment with the arcuate
cutouts forming armholes above such side seams, and the edge
portions of the neck opening and armholes are folded back against
the adjacent fabric and secured to the latter by longitudinally
stretchable stitching extending along such edge portions, whereby
the neck opening and armholes and the upper ends of the side seams
are finished off without resort to tacking of the side seams and
separately cut bindings or tapes for the neck opening and
armholes.
In a preferred embodiment of the invention, the bottom edge portion
of the garment body is folded back against the adjacent fabric and
secured thereto by longitudinally stretchable stitching for
finishing off the bottom of the garment body and the lower ends of
the side seams. Further, the knit fabric of the single
substantially rectangular fabric piece constituting the garment
according to this invention is preferably formed to be more
stretchable in its longitudinal direction than in the direction at
right angles thereto, so that the shoulder straps of the garment
will be relatively extensible.
The above, and other objects, features and advantages of this
invention, will be apparent in the following detailed description
of an illustrative embodiment thereof which is to be read in
connection with the accompanying drawings.

DESCRIPTION OF A PREFERRED EMBODIMENT
Referring to the drawings in detail, and initially to FIG. 1
thereof, it will be seen that undershirts and similar sleeveless
garments according to this invention are preferably formed from a
tube 10 of circularly knitted fabric which is more stretchable or
yieldable in its circumferential or lateral direction indicated by
the arrows a than in the lengthwise direction indicated by the
arrows b. A particularly desirable circular or tubular knit fabric
for garments according to this invention is the knitted pile fabric
disclosed in detail in U.S. Pat. No. 3,111,829 issued to me on Nov.
26, 1963, and which generally comprises a base or ground of stretch
nylon or other synthetic yarns and a random arrangement of loops of
cotton or synthetic yarns extending from the base or ground and
having various lengths to give the face of the fabric a shaggy
appearance which is characteristic of "poodle" type fabrics.
After the knit fabric tube 10 has been flattened to provide
superposed layers of material joined together along the opposite
folded side edges 12 and 14 of the flattened tube, a series of
side-by-side disposed garment forming blanks 16 are die cut or
stamped therefrom. It will be seen that, in die-cutting or stamping
the garment forming blanks 16 from flattened tube 10, the latter is
cut along the folded side edges 12 and 14 so as to separate the
superposed layers of material and along spaced apart lateral lines
18 which extend inwardly from side edges 12 and 14 to the ends of
centered oval lines 20. Further, the flattened tube 10 is cut along
oval lines 22, each of which is centered between adjacent oval
lines 20 but preferably offset laterally to one side of the
longitudinal median of the flattened tube.
As a result of the foregoing cutting of the flattened tube 10, each
of the knit fabric pieces or blanks 16 derived therefrom is shown
on FIG. 2 to be of substantially rectangular configuration and to
have opposite end portions 24 and 26 which are dimensioned to
define front and back body portions, respectively, of the garment
to be produced therefrom. By reason of the oval cut lines 20
between successive blanks 16, each blank 16 is shown to have
arcuate cutouts 20a in its opposed relatively long or side edges,
with such cutouts 20a being centered between the end portions 24
and 26, while the oval cut lines 22 provide each blank 16 with a
neck opening 22a which is centered laterally between the arcuate
cutouts 20a and which extends further toward end portion 24 than
toward end portion 26. It will be apparent that the fabric of blank
16 between arcuate cutouts 20a and neck opening 22a defines
seamless shoulder strap portions 28 which integrally connect the
end portions 24 and 26. Further, in each blank 16, the direction a
of maximum stretchability is shown to extend longitudinally by
reason of the fact that each blank 16 extends laterally in respect
to flattened tube 10 when cut from the latter.
Each blank 16 is formed into an undershirt or similar sleeveless
garment by folding the blank along the transverse medial line 30 so
that end portion 24 forming the front 24a of the body is superposed
on end portion 26 forming the back 26a of the body. Preferably,
such folding is effected so that the eventual outer surfaces or
faces of the knit fabric of end portion 24 and 26 will confront
each other. When the blank 16 is thus folded, the front of neck
opening 22a is deeper than the back of the neck opening, as shown
on FIG. 3. After folding of the blank, the adjacent or respective
side edges of front body 24a and back body 26a are joined together
by longitudinally stretchable stitching to form side seams 32. Such
longitudinally stretchable stitching may be simply constituted by
differential stitches formed with stretch polyester or nylon
thread. Upon the formation of the side seams 32, the arcuate
cutouts 20a of the blank 16 define armholes 20b above the side
seams.
In accordance with the present invention, the neck opening 22a and
the armholes 20b are finished off by turning back the edge portions
thereof, as at 22'a and 20'b, respectively (FIG. 4), and then
securing the folded back edge portions 22'a and 20'b to the
underlying adjacent fabric by means of longitudinally stretchable
stitching, for example, similar to the stitching of side seams 32,
which extends continuously along the folded back edge portions 22'a
and 20'b, as at 22"a and 20"b on FIGS. 4,5 and 6. Since the knit
fabric of blank 16 has two-way stretchability, no problems are
encountered in folding back the edge portions 22'a and 20'b along
the closed curves of neck opening 22a and armholes 20b. Further,
the edge portions 22'a and 20'b are preferably folded back onto the
base or ground side of the knit fabric, that is, the surface of
knit fabric which will be at the inside of the completed garment so
that each folded-back edge portion 20'b and the stitching 20"b
extending therealong at the bottom of the respective armhole 20b
will finish-off and secure the upper end of side seam 32 at the
respective side of the garment, as at 33 on FIG. 5.
Further, the bottom of the body of the garment is finished off by
turning back the bottom edge portion 34 (FIGS. 5 and 6) onto the
base or ground side of the adjacent knit fabric, and then securing
the folded or turned back edge portion 34 to the underlying
adjacent fabric by means of longitudinally stretchable stitching,
for example, similar to the stitching of side seams 32, which
extends continuously along folded back edge portion 34, as at 35.
It will be apparent that the folded back edge portion 34 and the
stitching 35 extending therealong at the opposite sides of the
garment body serve to finish off and secure or lock the lower ends
of the side seams 32.
Following the finishing off of the neck opening 22a and armholes
20b and of the bottom of the garment body, as described above, the
completed garment appearing on FIGS. 4 and 5 is everted or turned
inside-out, as shown on FIG. 6, so that the face or pile side of
the knit fabric will face outwardly and the folded back edge
portions 20'b, 22'a and 34 will be at the inside of the
garment.
It will be appreciated that, in the completed garment, the folded
back edge portions 20'b,22'a and 34 which respectively finish the
armholes, neck opening and bottom of the garment are of the same
two-way stretchable knit fabric as the remainder of the garment and
thus do not significantly restrict the stretching of the garment.
Since the oval cut lines 20 and 22 (FIG. 1) which eventually define
the armholes 20b and neck opening 22a of the garment are elongated
in the direction of the maximum stretchability of the knit fabric,
the major portions of the peripheries of the armholes 20b and of
the neck opening 22a extend generally in the direction of maximum
stretchability in the completed garment to permit the maximum
extension or stretching of the neck opening and armholes. Further,
the shoulder straps 28 also extend generally in the direction of
maximum stretchability of the knit fabric. The foregoing
characteristics all contribute to the provision of a garment that
is adapted to fit wearers of various sizes and also to accommodate
the growth of an infant or child over an extended period of
time.
Since the shoulder straps 28 are devoid of seams extending
thereacross at the tops of the shoulder straps, and since the neck
opening and armholes are finished off merely by a single additional
fabric thickness in the folded back edge portions 20'b and 22'a,
thick bulges of fabric are not present in the shoulder straps 28 so
that the garment affords optimum comfort to the wearer even when a
load is borne by the wearer's shoulder.
It will also be apparent that the described garment according to
this invention makes possible very substantial economies in its
mass production. In this connection, it should be noted that the
folded back edge portions 20b and 22a which finish off the armholes
and neck opening of the completed garment are derived from the
fabric of flattened tube 10 that would otherwise be cut away and
wasted if the oval cut lines 20 and 22 were dimensioned to
correspond to the desired sizes of the armholes and neck opening of
the completed garment. Thus, no additional fabric is required for
finishing the armholes and neck opening, and there is a further
saving of the additional labor required when, as in the prior art,
the neck opening and armholes are finished off by separately cut
bindings or tapes. It is also to be appreciated that, in the
garment according to this invention, the stretchable stitching
20"b, 22"a and 35 forms a blind seam in each case so that the cost
of tacking or locking the ends of these seams, as well as the cost
of tacking the ends of side seams 32 which are secured by stitching
20"b and 35, can be eliminated.
Although an illustrative embodiment of the invention has been
described in detail herein with reference to the accompanying
drawings, it is to be understood that the invention is not limited
to that precise embodiment, and that various changes and
modifications may be effected therein by one skilled in the art
without departing from the scope or spirit of the invention as
defined in the appended claims.
