ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a headgear frame for an embroidering machine adapted to be used for hold a headgear when the cap portion of the headgear is to be embroidered by an embroidering machine.
2. Description of Related Art
FIGS. 11 and 12
show a well-known headgear
61
. This headgear
61
is provided with a cap portion
62
to be put on a head and a visor
66
stitched to the front portion
65
of the cap portion
62
. To an open edge portion of the cap portion
62
, there are stitched a mesh portion
63
arranged on the back side of the front portion
65
and a ring-shaped sweatband portion
64
arranged on the inner side of the cap portion
62
.
The cap portion
62
is formed by stitching a plurality of (e.g., six) cloth sheets
67
having generally triangular shapes. In the stitched portion
71
of each cloth sheet
67
, there is arranged a margin to stitch of each cloth sheet
67
on the inner side of the cap portion
62
. Moreover, each margin to stitch is covered with a cloth band
68
which is arranged on the inner side of the cap portion
62
along the stitched portion
71
. Thus, this stitched portion
71
is made thicker than the remaining portions of the cap portion
62
.
In the headgear
61
, as indicated by double-dotted lines in
FIG. 12
, the mesh portion
63
and the sweatband portion
64
are extracted from the inner side of the cap portion
62
. As indicated by solid lines in
FIGS. 11 and 12
, the leading end side
63
a
of the mesh portion
63
is folded back to envelop the sweatband portion
64
. In this state, the headgear
61
is mounted on the headgear frame. An embroidery range
69
is provided in the front portion
65
of the cap portion
62
, for example, as indicated by the double-dotted lines at the cap portion
62
in FIG.
11
.
As shown in
FIGS. 13 and 14
, a headgear frame
81
of the prior art for embroidering the front portion
65
of the cap portion
62
of the headgear
61
is provided with a receiving frame
82
adapted to be inserted into the inner side of the cap portion
62
for receiving the peripheral portion
70
of the embroidery range
69
of the front portion
65
, and a holding band
83
made of an elastic metal sheet and wound around the cap portion
62
for holding the peripheral portion
70
between itself and the receiving frame
82
. The holding band
83
is provided with a pair of band members
84
and
85
for holding the upper and lower peripheral portions
70
a
and
70
b
in the headgear height direction of the embroidery range
69
all over the headgear peripheral direction, and a pair of joint portions
88
for holding the peripheral portions
70
c
and
70
c.
The band member
84
on the top side and the joint portions
88
are provided with a slip preventing rubber member
86
on the face opposed to the receiving frame
82
. Thus in the headgear frame
81
of the prior art, the holding band
83
holds the peripheral portion
70
of the embroidery range
69
exclusively.
The headgear frame
81
supports, where it is attached to a drive unit
101
for driving itself, the embroidery range
69
just above a needle plate
105
in a bed
102
of the machine. By the cooperations among the headgear frame
81
driven by the drive unit
101
, a needle
104
carried vertically movably by a machine head
103
and a rotating hook built in the bed
102
, moreover, an embroidered pattern is formed in the embroidery range
69
.
In the upper face of the receiving frame
82
, there are formed a first aperture
89
for arranging the embroidery range
69
and a second aperture
90
for releasing the margins to stitch in the stitched portions of the cap portion
62
, the visor
66
, the mesh portion
63
and the sweatband portion
64
.
In a headgear frame
91
of the prior art for embroidering the generally entire periphery of the cap portion
62
of the headgear
61
, as shown in
FIG. 15
, the upper side and the lower side of the visor
66
are individually held on a receiving frame
92
by a holding band
93
having a pair of upper and lower band members
94
and
95
. The band member
94
for holding the upper side of the visor
66
is provided along the edge portion of the band member
94
on the visor side with a positioning member
96
for biting into a stitched portion
77
between the cap portion
62
and the visor
66
. Here, the shown headgear
61
is not provided with the mesh portion
63
.
However, the headgear frames
81
and
91
of the prior art are encountered by the following problems (1) to (5).
(1) To the stitched portion
77
between the cap portion
62
and the visor
66
, there are additionally stitched the mesh portion
63
and the sweatband portion
64
. On the inner side of the cap portion
62
in the stitched portion
77
, there are concentrated the margins to stitch of the cap portion
62
, the. visor
66
, the mesh portion
63
and the sweatband portion
64
. When the headgear
61
having the mesh portion
63
and the sweatband portion
64
folded back is to be mounted on the headgear frame
81
of the prior art for embroidering the front portion
65
of the cap portion
62
, moreover, the folded-back cloth and the aforementioned margins to stitch ride on the upper face of the root end of the receiving frame
82
, as shown in FIG.
14
. Therefore, the front portion
65
of the cap portion
62
on the side of the visor considerably floats from the needle plate
105
. This float is different according to the structure of the stitched portion
77
and the kind/thickness of the cloth of the individual portions composing the headgear
61
but is exemplified by about 3 to 7 mm. If the visor side of the front portion
65
is held and fastened by the band member
85
made of a flat sheet (which may include the rubber member), the holding is made due to the step from the upper face of the receiving frame
82
receiving the mesh portion
63
and the sweatband portion
64
such that the band member
85
drops oppositely of the visor side from the stitched portion
77
between the front portion
65
and the visor
66
, as indicated by arrows (of double-dotted lines) in FIG.
14
. This drop is prominently found at the stitched portion
77
between the cap portion
62
and the visor
66
at the center of the front portion
65
. Especially at the center of the front portion
65
of the cap portion
62
, therefore, there arises a problem that the portion near the visor
66
is difficult to embroider. In the vicinity of the boundary between the cap portion
62
and the visor
66
of the headgear
61
, for example, the embroidered pattern extending in parallel with that boundary has to be formed by shifting its entirety to the top side by considering the aforementioned drop of the band member
85
.
In the headgear frame
91
of the prior art for embroidering the substantially entire periphery of the cap portion
62
, on the other hand, the positioning member
96
bites into the stitched portion
77
between the cap portion
62
and the visor
66
to hold the stitched portion
77
but not the cloth of the front portion
65
of the cap portion
62
. Where the cap portion
62
, the visor
66
, the mesh portion
63
or the sweatband portion
64
is made of thick cloth (especially, a baseball cap), as shown in
FIG. 15
, the cloth largely floats at the front portion
65
of the cap portion
62
on the side of the visor
66
so that it flaps while being embroidered, to raise a problem that the embroidery quality drops.
(2) As described in (1), the visor side of the front portion
65
of the cap portion
62
largely floats with respect to the needle plate
105
. In the headgear
61
having the large float, the band member
85
on the visor side largely floats from the upper face of the receiving frame
82
so that the band member
84
on the top side, as formed integrally with the band member
85
on the visor side, also floats from the upper face of the receiving frame
82
to raise a problem that the holding of the cap portion
62
by the band member
84
