Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a headgear frame for a sewing machine for embroidering the peripheral portion of a headgear.
2. Description of the Related Art
A conventional headgear frame
100
for a sewing machine is provided, for example, with a receiving frame
101
formed into a cylindrical shape and a holding band
102
having a belt shape, as shown in FIG.
5
.
When a headgear
1
is to be embroidered, first of all, the receiving frame
101
of the headgear frame
100
is mounted on the (not-shown) set jig. The headgear
1
is fitted on the outer circumference of the receiving frame
101
and is then clamped and fixed on its outer circumference by the holding band
102
of the headgear frame
100
.
At this time, one end
102
a
of the holding band
102
is hinged at a position apart from the receiving frame
101
to the side of the outer circumference, whereas the other end
102
b
of the holding band
102
is hooked at a position apart from the receiving frame
101
to the side of the outer circumference. As a result, the vicinities
1
b
of the left and right ends of the headgear
1
, which are held by the vicinities of the one end
102
a
and the other end
102
b
of the holding band
102
, are not sufficiently held so that they easily float from the receiving fame
101
and wrinkle. Since embroidered patterns are not neatly formed unless the vicinities
1
b
of the left and right ends of the headgear
1
are sufficiently tensed, the wrinkles must be smoothed out, which requires experience and takes a long time.
SUMMARY OF THE INVENTION
An object of the present invention is to provide a headgear frame capable of clamping a headgear without any wrinkle.
In the invention, therefore, there is adopted the following means, as will be individually described with reference to
FIGS. 1

; and a holding band
12
adapted to be wound on the outer side of the headgear
1
for clamping the headgear
1
between the holding band
12
and the receiving frame
11
, wherein at least one of one end
12
a
and the other end
12
b
of said holding band (
12
(e.g., both of one end
12
a
and the other end
12
b
in a shown embodiment) is hinged or hooked at a position apart (by a distance indicated by arrow S) from the receiving frame
11
to the outer circumference,
characterized: in that push members
13
projected toward the receiving frame
11
are provided in at least one (e.g., both in the shown embodiment) of the vicinities of the one end
12
a
and the other end
12
b
, as apart from the receiving frame
11
, of the band edge (e.g., the band edge on this side in the shown embodiment) of the holding band
12
; and in that corresponding portions
2
of the headgear
1
when clamped are pushed and tensed by said push members
13
so that they may not float from the receiving frame
11
.
The headgear
1
includes a cap, a hat, a beret and any others which can be embroidered and worn on the head.
The push members
13
can be exemplified by either a mode (

When the headgear
1
is to be fixed with the holding band
12
, the visor
4
of the headgear
1
is inserted at first into an opening
15
of the band central portion; and
The corresponding portions
2
(i.e., the left and right end portions in the shown embodiment) of the headgear
1
are so pushed and tensed by the push members
13
at the end portions of the holding band
12
that they are not wrinkled, and the other end
12
b
of the holding band
12
is hooked and fixed.
The following effects can be obtained according to this headgear frame
10
;
The headgear
1
is smoothed out at its left and right end portions so that its setting time is shortened; and
The headgear
1
can be decoratively embroidered even at both end portions of the embroidered range (e.g., a horizontal range of 270 degrees).

which is made vertically movable in the (not-shown) machine head. And, a headgear (cap)
1
, as held on the headgear frame apparatus
9
, is embroidered by the association between the needle
93
to be driven on the basis of embroidering data and the aforementioned hook.
The headgear frame apparatus
9
is provided for supporting the embroidering range of the headgear
1
in a proper position just over the cylindrical bed
91
. The headgear frame apparatus
9
is constructed to include: a support frame
40
made slidable in the direction Y along the guide rail
62
; a rotary drive frame
30
so supported on the support frame
40
as to rotate on an axis parallel to the direction Y; the headgear frame

1
and replaceably engaged to outside of the rotary drive frame
30
; elastic plates
41
mounted on a stay
45
, as projected forward from the support frame
40
, and extended sideways (to the left and right sides in the shown embodiment) of the cylindrical bed
91
; and auxiliary rollers
42
provided rotatably at the leading ends of the elastic plates
41
and rotating in abutment against boundary corner portion
7
between a circumferential portion
5
and a crest portion
6
of the headgear
1
clamped by the headgear frame
10
.
This headgear frame
10
is provided, as shown in
FIGS. 1
to
3
, with a cylindrical receiving frame
11
to be inserted into the headgear
1
, and a holding band
12
adapted to be wound on the outer side of the headgear
1
to clamp the headgear
1
between itself and the receiving frame
11
.
This receiving frame
11
is provided with a brim
23
disposed generally at the center of its longitudinal direction. On the front face of the brim
23
, there are provided a hinging portion
16
and a hooking portion
17
which are spaced from each other in the circumferential direction of the receiving frame
11
.
The hinging portion
16
and hooking portion
17
are individually disposed at positions spaced apart from the outer circumference of the receiving frame
11
(by a distance indicated by arrow S). To the hinging portion
16
near the receiving frame
11
, there is hinged one end
12
a
of the holding band
12
, the other end
12
b
of which is removably hooked on the hooking portion
17
near the receiving frame
11
.
Of the band edge (i.e., the band edge on this side in the shown embodiment) of the holding band
12
, both portions in the vicinities of the one end
12
a
and the other end
12
b
apart from the receiving frame
11
are provided with push members
13
which are projected toward the receiving frame
11
. By these push members
13
, the headgear
1
is so pushed and tensed, when clamped, at its corresponding portions
2
that it may not float from the receiving frame
11
. The push members
13
are a plurality of push members
13
which are raised stepwise toward the one end or the other end.
In the holding band
12
, there is formed a horizontally elongated opening
15
for passing the visor
4
of the headgear
1
therethrough. On the intermediate portion of the front edge of the opening
15
, there are formed a number of saw-toothed projections
15
a
which can bite into the stitched portion between the visor
4
and the circumferential portion
5
of the headgear
1
from the outer side of the headgear
1
.
At the hooking portion
17
near the receiving frame
11
and at the other end
12
b
of the holding band
12
, respectively, as shown in
FIG. 3
, there are provided a combination of a hooking member
18
and a pair of regulating members
19
which make a V-shaped angled side face
20
with the hooking member
18
on both sides of the hooking member
18
, and a ring
21
hooked by the hooking member
18
. When the ring
21
is hooked by the hooking member
18
, it bites into the V-shaped angled side face
20
so that it does not go out of position with respect to the hooking member
18
(especially in the band width direction). The ring
21
is provided at its leading end with a C-shaped portion
22
. Here, this C-shape includes one which curves smoothly and one which is squarish and bends. The hooking member
18
is made substantially as wide as the internal width of the C-shaped portion
22
, and the clearance of the paired regulating members
19
is made substantially as wide as the external width of the C-shaped portion
22
.
At the receiving frame
11
, a curved plate
26
is projected forward of the receiving frame
11
along the inner circumferential edge of the front end of the receiving frame
11
, and a support plate portion of the curved plate
26
is projected forward of the receiving frame
11
on the outer circumference of the receiving frame
11
between the hinging portion
16
and the hooking portion
17
. The curved plate
26
is provided at its front end edge with a number of projections
14
which are so arranged as can bite into the stitched portion with the circumferential portion
5
of a next-to-skin portion
3
. The support plate portion is provided on its outer circumference with a pair of fitting members
24
which are spaced from each other in the circumferential direction of the receiving frame
11
. This support plate portion is inserted into the headgear
1
to clamp the back side of the headgear
1
between the support plate portion and a holding clip
25
which is fitted in the fitting members
24
from the outer side of the headgear
1
.
Next, the headgear
1
is clamped by the headgear frame
10
thus constructed in the following manner:
(1) The headgear frame
10
is set in the (not-shown) set jig;
(2) The other end
12
b
of the holding band
12
is released from the receiving frame
11
of the headgear frame
10
;
(3) The headgear
1
is mounted on the receiving frame
11
while peeling out the next-to-skin portion
3
. The headgear
1
is positioned to have its back side located on the side of the support plate portion of the receiving frame
11
. At this time, the stitched portion of the headgear next-to-skin portion is made to engage with the saw-toothed projections
14
of the receiving frame
11
(so as to prevent dislocations);
(4) When the headgear
1
is fixed by the holding band
12
, the visor
4
of the headgear
1
is inserted at first into the opening
15
at the band central portion, and the holding band
12
is wound on the headgear
1
;
(5) The push members
13
at the both end portions of the holding band
12
push and tense the corresponding portions
2
(i.e., the left and right end portions in the shown embodiment) of the headgear
1
so that the corresponding portions
2
may not float from the receiving frame
11
, and the other end
12
b
of the holding band
12
is hooked and fixed while eliminating the wrinkles; and
(6) Moreover, the back side of the headgear
1
is lightly pulled downward by one hand to tense the left and right end portions of the headgear
1
, and the holding clip
25
is mounted in the fitting members
24
through the headgear
1
by the other hand.
The following effects can be achieved according to the headgear frame
10
:
i) The left and right end portions of the headgear
1
are easily smoothed out to shorten the setting time of the headgear
1
; and
ii) The both end portions of the embroidering range (e.g., the horizontal range of 270 degrees) of the headgear
1
are tensed so that even the both end portions can be decoratively embroidered.
Here, the invention should not be limited to the aforementioned construction of the embodiment but can be embodied by modifying it suitably without departing from the gist thereof, as in the following:
(1) The invention can be modified by a mode in which the push members
13
are formed into a generally triangular shape and raised gradually toward one end or the other end;
(2) The invention is applied to the headgear frame
10
, in which either of the one end
12
a
or the other end
12
b
of the holding band
12
is hinged or hooked at a position apart from the receiving frame
11
toward the outer circumference, and the vicinity of either one end
12
a
or the other end
12
b
apart from the receiving frame
11
is provided with the push members
13
projected toward the receiving frame
11
; and
(3) The fitting members
24
, the holding clip
25
and the curved plate
26
are omitted.
As many apparently widely different embodiments of this invention may be made without departing from the spirit and scope thereof, it is to be understood that the invention is not limited to the specific embodiments thereof except as defined in the appended claims.
