of the sewing machine 1", the upper side thereof is referred to as
"upper side of the sewing machine 1" and the lower side thereof is
referred to as "lower side of the sewing machine 1", and the side
of the paper toward the viewer is referred to as "left side of the
sewing machine 1" and the side thereof away from the viewer is
referred to as "right side of the sewing machine 1".
[0028] As shown in FIG. 1, the sewing machine 1 has a right-to-left
directionally long bed body portion 2, a pillar 5 that is erected
upward from the right end of the bed body portion 2, and an arm
portion 6 that extends leftward from the upper end of the pillar 5
and faces the bed body portion 2. The left end portion of the arm
portion 6 is referred to as a head portion 7.
[0029] The bed body portion 2 is comprised of a bed portion 3 that
extends from the bottom of the pillar 5, and a free arm-portion 4
that is extended a configuration such that one end thereof is
supported at a substantially center position of the left end of the
bed portion 3. The back-to-forth directional width of the free arm
portion 4 is about 2/3 of the width of the bed portion 3. Further,
the upper surface of the bed portion 3 is positioned substantially
at the same height as the height of the free arm portion 4, so that
the upper surfaces of the bed portion 3 and the free arm portion 4
are combined to form a substantially horizontal surface.
[0030] Provided on the front surface of the arm portion 6 is a
liquid crystal display (LCD) 16 that includes a touch panel. The
LCD 16 displays the keys, etc., for inputting sewing pattern and
sewing conditions. A user's touch at a position corresponding to
any one of those input keys will be detected by the touch panel.
Thus, such a configuration enables the user to select a sewing
pattern and the sewing conditions. The free arm portion 4 houses a
feed dog back-to-forth movement mechanism (not shown) and a feed
dog up-and-down movement mechanism (not shown) that drive a feed
dog (not shown), a feed adjustment pulse motor (not shown) that
adjusts a feed amount of a work cloth by the feed dog, a shuttle
(not shown) that contains a bobbin thread, etc. At the lower end of
the head portion 7, a sewing needle 8 and a presser foot 9 are
provided.
[0031] As shown in FIG. 2, at the front side of the left side
surface of the bed portion 3, a rectangular recessed engagement
portion 20 is formed. The engagement portion 20 is disposed at a
substantially center position in the up-and-down direction at the
front side of the left side surface of the bed portion 3. The
engagement portion 20 may be formed in the shape of a substantially
rectangular frame as viewed from the side whose longitudinal
direction is in the up-and-down direction. Further, in the
engagement portion 20 (hereinafter referred to as "first female
engagement portion 20"), a female electrical connector 24 is
provided. The female electrical connector 24 is used by the sewing
machine 1 to control the operations of an embroidery unit 30 (see
FIG. 3 later) when the embroidery unit 30 is attached. When the
female electrical connector 24 and an electrical connector 37 (see
FIG. 3 later) that is provided to the embroidery unit 30 (see FIG.

control the embroidery unit 30 (see FIG. 3 later) through
electrical communications.
[0032] At the upper front side of the left side surface of the free
arm portion 4, a substantially rectangular recessed portion
(hereinafter referred to as "second female engagement portion 21)
whose longitudinal direction is in the up-and-down direction is
formed over the front side surface.
[0033] Next, an outlined configuration of the embroidery unit 30
will be described below with reference to FIGS. 3 and 4. The
embroidery unit 30 is used to sew an embroidery in a configuration
such that the embroidery unit 30 is attached to the bed body
portion 2 (see FIG. 1) of the sewing machine 1. In the following
description, with reference to FIG. 4, the left side of the paper
is referred to as "front side of the embroidery unit 30" and the
right side thereof is referred to as "rear side of the embroidery
unit 30", the upper side thereof is referred to as "upper side of
the embroidery unit 30" and the lower side thereof is referred to
as "lower side of the embroidery unit 30", and the side of the
paper toward the viewer is referred to as "right side of the
embroidery unit 30" and the side thereof away from the viewer is
referred to as "left side of the embroidery unit 30".
[0034] As shown in FIG. 3, the embroidery unit 30 has a
laterally-placed substantial U-shape in plan view. The
back-to-forth directional length of a body portion of the
embroidery unit 30 is a little larger than the back-to-forth
directional length of the bed body portion 2 (see FIG. 1) of the
sewing machine I (see FIG. 1). Further, the right-to-left
directional length of the body portion of the embroidery unit 30
may be about 1.5 times the length of the free arm portion 4 (see
FIG. 1). The shape of a sandwiched portion 46 at the center of the
laterally-placed substantial U-shape in plan view may be almost the
same shape of the free arm portion 4 (see FIG. 1) of the sewing
machine 1 in plan view. The embroidery unit 30 may be used in a
configuration such that the sandwiched portion 46 is fitted to the
free arm portion 4 (see FIG. 1) of the sewing machine 1 (see FIG.
1).
[0035] The embroidery unit 30 has a box-shaped structure that
includes an upper planar portion 31, a peripheral wall portion 32,
and a bottom portion (not shown). The peripheral wall portion 32
runs along the peripheral borders of the upper planar portion 31
and the bottom portion (not shown) and extends perpendicular to the
upper planar portion 31 and the bottom portion (not shown). The
height of the peripheral wall portion 32 is almost the same as the
vertical width of the bed body portion 2 (see FIG. 1) of the sewing
machine 1 (see FIG. 1).
[0036] The embroidery unit 30 may be provided with a Y-carriage
mechanism 34 that protrudes upward above the upper planar portion
31. The Y-carriage mechanism 34 incorporates a Y-directional
transport mechanism that may be used to transport an embroidery
frame 33 in the Y-direction, which is the back-to-forth direction
of the bed body portion 2(see FIG. 1) of the sewing machine 1.
Further, An X-directional transport mechanism (not shown) may be
incorporated below the upper planar portion 31. The X-directional
transport mechanism may be used to transport the Y-carriage
mechanism 34 in the X-direction (right-to-left direction of the bed
body portion 2), which is orthogonal to the Y-direction. Further,
in the front part of the upper planar portion 31, a slit 39 may be
formed that extends in the right-to-left direction. The
X-directional transport mechanism and the Y-carriage mechanism 34
are connected to each other in such a manner so as to sandwich the
slit 39. If the X-directional transport mechanism and the
Y-carriage mechanism 34 operate in this configuration, the
embroidery frame 33 may operate. Such a configuration may enable
the movement of the embroidery frame 33 to an arbitrary position in
the X-Y plane.
[0037] Further, the embroidery unit 30 may include two arm portions
47 and 48 that protrude rightward. An engagement wall 35 protrudes
from the right side peripheral wall 44 at the end of a front-side
arm portion 47. The engagement wall 35 has such a shape that
rectangular walls are placed together to form a substantially
rectangular frame, as viewed in side plan, whose longitudinal
direction is in the up-and-down direction. In a portion enclosed by
the engagement wall 35 (hereinafter referred to as "first
engagement portion 35"), an electrical connector 37 may be
incorporated. The first engagement portion 35 faces the first
female engagement portion 20 (see FIG. 1) that is formed as a
recess in the bed portion 3 (see FIG. 1) when the embroidery unit
30 is attached to the sewing machine 1 (see FIG. 1). When the
embroidery unit 30 is attached to the sewing machine 1 (see FIG.
1), the first engagement portion 35 and the first female engagement
portion 20 (see FIG. 2) are engaged with each other so that the
embroidery unit 30 may be held by the sewing machine 1 (see FIG.
1). Moreover, the electrical connector 37 that is incorporated in
the portion enclosed by the engagement wall 35 serves to
electrically connect to the female electrical connector 24 of the
sewing machine 1 (see FIG. 1). When the first engagement portion 35
and the first female engagement portion 20 (see FIG. 1) are engaged
with each other, the female electrical connector 24 and the
electrical connector 37 are electrically connected to each
other.
[0038] Further, as shown in FIG. 4, a protruding portion 43
(hereinafter referred to as "second engagement portion 43")
protrudes from a portion where a rear-side peripheral wall portion
(not shown) of the front-side arm portion 47 (see FIG. 3) of the
embroidery unit 30 comes in contact with a left-side peripheral
wall 45 of the sandwiched portion 46 sandwiched between the arm
portions 47 and 48. The second engagement portion 43 may be
substantially T-shaped as viewed in side plan, having the rear-side
peripheral wall portion (not shown) as its bottom. When the
embroidery unit 30 is attached to the sewing machine 1, the second
engagement portion 43 faces the second female engagement portion 21
(see FIG. 1) that is formed as a recess in the free arm portion 4
(see FIG. 1). When the embroidery unit 30 is attached to the sewing
machine 1 (see FIG. 1), the second engagement portion 43 and the
second female engagement portion 21 are engaged with each other so
that the embroidery unit 30 may be held by the sewing machine 1
(see FIG. 1).
[0039] As shown in FIG. 3, in the peripheral wall portion 32 of the
outer surfaces of the arm portion 47, at the middle in the
right-to-left direction, a female locking portion 40 that has a
substantially rectangular recessed shape, as viewed in side plan,
and whose longitudinal direction is in the right-to-left direction,
extends over the upper planar portion 31. Further, from a portion
where the female locking portion 40 comes in contact with the upper
planar portion 31, a locking portion 41 protrudes (hereinafter, a
combination of the female locking portion 40 and the locking
portion 41 is referred to as "female locking portion 42"). Locking
portions 67 (see FIG. 5 later) are locked at the locking portion 41
when the embroidery unit cover 60 is placed over the embroidery
unit 30 from above. Such a configuration enables the embroidery
unit cover 60 (see FIG. 6 later) to be fixed to the embroidery unit
30.
[0040] Next, an outlined configuration of the sewing machine 1 in a
configuration such that the embroidery unit 30 is attached will be
described below with reference to FIG. 5.
[0041] As shown in FIG. 5, in a configuration such that the
embroidery unit 30 is attached to the sewing machine 1 in order to
sew an embroidery, the free arm portion 4 of the sewing machine 1
is fitted to the sandwiched portion 46 (see FIG. 3) having the
laterally-placed and substantial U-shape of the embroidery unit 30.
Then, the first engagement portion 35 (see FIG. 3) and the first
female engagement portion 20 (see FIG. 1) are engaged with each
other, while the second engagement portion 43 (see FIG. 3) and the
second female engagement portion 21 (see FIG. 1) are engaged with
each other. Then, the embroidery unit 30 may be held by the sewing
machine 1 in a configuration such that an upper surface 51 of the
bed portion 3 of the sewing machine 1, an upper surface 52 of the
free arm portion 4, and the upper planar portion 31 of the
embroidery unit 30 are combined to form a substantially horizontal
surface. The embroidery unit 30 is stably supported on the floor
surface because the vertical width of a side surface 53 of the bed
portion 3 of the sewing machine 1 and the vertical width of the
peripheral wall portion 32 of the embroidery unit 30 are almost the
same width as each other.
[0042] In this configuration, the female electrical connector 24
(see FIG. 1) of the sewing machine 1 may be electrically connected
to the electrical connector 37 (see FIG. 3) of the embroidery unit
30. Therefore, electrical communications are established between
the sewing machine 1 and the embroidery-unit 30. In response to
input information entered by the user through the LCD 16, the
sewing machine 1 controls the X-directional transport mechanism and
the Y-carriage mechanism 34 of the embroidery unit 30, thereby
operating the embroidery frame 33. Accordingly, an embroidery may
be sewed by the sewing machine 1.
[0043] Next, an outlined configuration of the embroidery unit cover
60 will be described below with reference to FIGS. 6-10. The
embroidery unit cover 60 can be placed over the embroidery unit 30
(see FIG. 3) and used as a cover to prevent dust, etc., from
entering the embroidery unit 30 (see FIG. 3). The embroidery unit
cover 60 can be attached to the sewing machine 1 (see FIG. 1) and
used also as a side table when sewing a pattern on a large work
cloth. In the following description, with reference to FIG. 6, the
left side of the paper is referred to as "left side of the
embroidery unit cover 60" and the right side thereof is referred to
as "right side of the embroidery unit cover 60", the upper side
thereof is referred to as "rear side of the embroidery unit cover
60" and the lower side thereof is referred to as "front side of the
embroidery unit cover 60", and the side of the paper toward the
viewer is referred to as "upper side of the embroidery unit cover
60" and the side thereof away from the viewer is referred to as
"lower side of the embroidery unit cover 60".
[0044] As shown in FIG. 6, the embroidery unit cover 60 has a
plate-shaped planar portion 61 having a substantially
laterally-placed U-shape in plan view as its upper surface. The
back-to-forth length of the embroidery unit cover 60 may be a
little larger than the back-to-forth length of the bed body portion
2 (see FIG. 1) of the sewing machine 1 (see FIG. 1). The
right-to-left length of the embroidery unit cover 60 may be about
1.5 times of the right-to-left length of the free arm portion 4
(see FIG. 1). The shape of the planar portion 61 may be almost the
same as the shape of the upper planar portion 31 (see FIG. 3) of
the embroidery unit 30 (see FIG. 3). Therefore, the embroidery unit
cover 60 can be placed over the embroidery unit 30 (see FIG. 3)
from the above. The shape of a sandwiched portion 79 sandwiched
between two arm portions 80 and 81 that extend rightward may be
almost the same as a planar shape of the free arm portion 4 (see
FIG. 1). Therefore, it is possible to fit the sandwiched portion 79
to the free arm portion 4 (see FIG. 1).
[0045] Among peripheral wall portions 64, 65, 68, and 69 (see FIG.
7 later) extending along the peripheral border of the planar
portion 61, a peripheral wall portion 64 at the end of the front
side arm portion 80 may be provided with a third engagement portion
62 that protrudes rightward. Further, at the front side of a
peripheral wall portion 65, on the left side surface of a
sandwiched portion 79, and sandwiched between the arm portions 80
and 81 extending rightward, a fourth engagement portion 63 that
protrudes rightward may be provided.
[0046] As shown in FIGS. 7 and 8, the embroidery unit cover 60 has
peripheral wall portions 64, 65, 68, and 69 that run continually
along the peripheral border of the planar portion 61 and that
extend vertically downward from the planar portion 61. The
peripheral wall portions 64, 65, 68, and 69 may be sufficiently
higher than the Y-carriage mechanism 34 (see FIG. 3) that protrudes
from the upper surface of the embroidery unit 30. The peripheral
wall portions 64, 65, 68, 69 have a height of about 2/3 of the bed
portion 3 (see FIG. 1). Therefore, the peripheral wall portions 64,
65, 68, 69 may be high enough to cover the Y-carriage mechanism 34
(see FIG. 3) in a configuration such that the embroidery unit cover
60 is used as a cover over the embroidery unit 30 (see FIG. 3).
[0047] On the outer front-side peripheral wall portion 68 and the
outer rear-side peripheral wall portion 69, downward protruding
locking portions 67 and 66 are respectively provided. At each end
of the locking portions 67 and 66, an inward protruding locking
portion may be provided. The protruding locking portion may be
configured so that it can be locked by the locking portion 41 (see
FIG. 3) of the embroidery unit 30 (see FIG. 3).
[0048] As shown in FIG. 8, the third engagement portion 62 that
protrudes from the peripheral wall portion 64 of the arm portion 80
and that extends rightward may have a structure such that
rectangular walls are placed together to form a substantially
rectangular frame shape in which the longitudinal direction is in
the vertical direction. The third engagement portion 62 may have
its lower portion sticking out from the lower end of the peripheral
wall portion 64 by about 1/4 of its longitudinal width. As shown in
FIG. 7, the fourth engagement portion 63 that protrudes from the
peripheral wall portion 65 of the sandwiched portion 79 sandwiched
between the two arm portions 80 and 81 and that extends rightward
may include walls that form a substantially E-shape as a whole, as
viewed in side plan. Further, due to its shape, the third
engagement portion 62 can be engaged with the first female
engagement portion 20 (see FIG. 1) in the sewing machine 1 (see
FIG. 1). In addition, due to its shape, the fourth engagement
portion 63 can be engaged with the second female engagement portion
21 (see FIG. 2) in the sewing machine 1 (see FIG. 1).
[0049] Furthermore, as shown in FIG. 9, within a portion of space
surrounded by the planar portion 61 and the peripheral wall
portions 64, 65, etc., a dividing wall 76 which divides the space
portion in the back-to-forth direction may be provided along an
edge on the opposite side of the sandwiched portion 79 having the
substantially laterally-placed U-shape in plan view. In one of the
portions divided by the dividing wall 76, substantially rectangular
solid-shaped support legs 72 and 75 may be axially and rotatably
supported and housed. The support legs 72 and 75 may be erected and
projected downward from the embroidery unit cover 60 when used, to
support the embroidery unit cover 60 in a configuration such that
the embroidery unit cover 60 is attached to the sewing machine 1
(see FIG. 1) so that the embroidery unit cover 60 may be used as a
side table. The support legs 72 and 75 may have substantially
rectangular solid-shaped support leg body portions 70 and 73,
support leg tip portions 71 and 74, and support leg axial portions
77 and 78, respectively.
[0050] The support leg axial portions 77 and 78 may be used to
axially support the support legs 72 and 75 on the embroidery unit
cover 60. The support leg axial portions 77 and 78 may be
respectively provided at the ends of the support leg body portions
70 and 73. The support legs 72 and 75 may be axially supported by
the embroidery unit 60 at the corners of the embroidery unit cover
60. The support legs 72 and 75 may be rotated about the support leg
axial portions 77 and 78 as their respective base axes to be
positioned in a substantially vertical posture and a horizontal
posture parallel to the back-to-forth direction. If the embroidery
unit cover 60 is used as an embroidery unit cover in a
configuration such that the embroidery unit cover 60 is placed over
the embroidery unit 30 (see FIG. 3), the support legs 72 and 75 may
be kept in the horizontal posture so that they may not interfere
with the embroidery unit 30 (see FIG. 3). On the other hand, if the
embroidery unit cover 60 is attached to the sewing machine 1 (see
FIG. 1) and used as a side table as shown in FIG. 10, the support
legs 72 and 75 may be kept in a substantially vertical posture to
support the embroidery unit cover 60. The embroidery unit cover 60
may be provided with butting portions (not shown). Therefore, if
the support legs 72 and 75 are rotated, the support legs 72 and 75
respectively abut against the butting portions and cannot be
rotated any more from the substantially vertical posture. Such a
configuration enables keeping the support legs 72 and 75 in the
substantially vertical posture. Further, to prevent the support
legs 72 and 75 from freely rotating, frictional resistance is
caused when the support legs 72 and 75 would rotate.
[0051] The support leg tip portions 71 and 74 may be disposed on an
end of the support legs 72 and 75 opposite to the support leg axial
portions 77 and 78, respectively. The support leg tip portions 71
and 74 may each comprise a semispherical tip portion whose
spherical surface faces toward the tip and a screw rod portion that
protrudes in the opposite direction to the spherical surface. The
screw rod portions may be screwed into respective screw holes in
the support leg body portion 70 and the support leg body portion
73.
[0052] As shown in FIG. 10, if the embroidery unit cover 60 is
attached to the sewing machine 1 and used as a side table, the
support legs 72 and 75 may be respectively rotated around the
support leg axial portions 77 and 78 as axes, and used in the
substantially vertical posture. By adjusting the degree of screwing
that the screw rod portions of the support leg tip portions 71 and
74 are screwed into the support leg body portions 70 and 73, it is
possible to adjust the entire lengths of the support legs 72 and
75. Therefore, the same embroidery unit cover 60 can be used as a
side table even if the sewing machine 1 is used on an uneven plane
or the embroidery unit cover 60 is attached to another sewing
machine.
[0053] Next, an outlined configuration of the embroidery unit cover
60 in a configuration such that the embroidery unit cover 60 is
placed over the embroidery unit 30 will be described below with
reference to FIG. 11.
[0054] As shown in FIG. 11, the embroidery unit cover 60 may be
placed over the embroidery unit 30 and used as a cover to prevent
dust, etc., from entering the embroidery unit 30. Further, in a
configuration such that the embroidery unit cover 60 is placed over
the embroidery unit 30, the locking portion 67 that protrudes from
the peripheral wall portion 68 of the embroidery unit cover 60 is
locked by the locking portion 41 (see FIG. 3) at the female locking
portion 42 of the embroidery unit 30. With such a configuration,
the embroidery unit cover 60 can be fixed to the upper side of the
embroidery unit 30. In plan view, the embroidery unit 30 and the
embroidery unit cover 60 may have almost the same shape, so that
the embroidery unit cover 60 can be tightly fitted to the
embroidery unit 30. Therefore, the space surrounded by the planar
portion 61 and the peripheral wall portion 68 of the embroidery
unit cover 60 may be used to cover the slit 39 (see FIG. 3) and the
Y-carriage mechanism 34 (see FIG. 3) which may particularly need
preventing the entry of dust, etc., in the embroidery unit 30.
[0055] In a configuration such that the embroidery unit cover 60 is
placed over the embroidery unit 30, the third engagement portion 62
that protrudes from the embroidery unit cover 60 and the first
engagement portion 35 that protrudes from the embroidery unit 30
may be disposed in parallel to each other in the up-and-down
direction. Similarly, the fourth engagement portion 63 provided on
the embroidery unit cover 60 and the second engagement portion 43
(see FIG. 3) provided on the embroidery unit 30 that may be engaged
with the second female engagement portion 21 (see FIG. 1) are
disposed in parallel to each other in the up-and-down
direction.
[0056] Next, an outlined configuration of the sewing machine 1 and
the embroidery unit cover 60 that are engaged with each other will
be described below with reference to FIGS. 12-14.
[0057] As shown in FIG. 12, when the embroidery unit cover 60 is
attached to the sewing machine 1 and used as a side table, the
sandwiched portion 79 which may have a substantially
laterally-placed U-shape in plan view in the embroidery unit cover
60 is fitted to the free arm portion 4 of the sewing machine 1.
Also, in this configuration, the first female engagement portion 20
(see FIG. 1) of the sewing machine 1 is engaged with the third
engagement portion 62 (see FIG. 6) of the embroidery unit cover 60,
while the second female engagement portion 21 (see FIG. 1) of the
sewing machine 1 is engaged with the fourth engagement portion 63
(see FIG. 6) of the embroidery unit cover 60.
[0058] With such a configuration, the upper surface 51 of the bed
portion 3 and the upper surface 52 of the free arm portion 4 of the
sewing machine 1, and the planar portion 61 of the embroidery unit
cover 60 are respectively held at positions at almost the same
height to form a substantially horizontal surface. Therefore, the
substantially horizontal surface can be used as a table surface. In
this configuration, because the right-to-left directional width of
the planar portion 61 of the embroidery unit cover 60 may be about
1.5 times of the right-to-left directional width of the free arm
portion 4 of the sewing machine 1, a substantially horizontal
larger surface portion can be used as a side table. The operation
mode may be switched halfway through a sewing process by using a
sewing machine, from utility stitch sewing that forms stitches
while a work cloth is fed with the feed dog, to embroidery sewing
that utilizes an embroidery unit. In such a configuration,
conventionally, a space for the embroidery unit cover that is
removed from the embroidery unit, would block the work space. In
contrast, the embroidery unit cover 60 of the present disclosure
can be used as a side table, so that the work space can be used
effectively. Moreover, the user need not prepare a side table
separately, thus improving the economic efficiency.
[0059] Further, as shown in FIGS. 13 and 14, the up-and-down width
of the peripheral wall portion 68 on the embroidery unit cover 60
is about 2/3 of the up-and-down width of the bed portion 3 in the
sewing machine 1. Therefore, when the embroidery unit cover 60 is
attached to the sewing machine 1, a gap may be formed below the
embroidery unit cover 60. In this configuration, the support legs
72 and 75 may be positioned in a substantially vertical posture,
and the embroidery unit cover 60 may be attached to the sewing
machine 1. In this configuration, the support legs 72 and 75 are
held to support the embroidery unit cover 60 at the end side
opposite to the sewing machine 1. Further, the support leg tip
portions 71 and 74 at the tips of the respective support legs 72and
75 may be adjusted as necessary. Therefore, it is possible to
adjust the lengths of the support legs 72 and 75 so that the
support legs 72 and 75 can adequately support the embroidery unit
cover 60.
[0060] Thus, it is possible to support one end side of the
embroidery unit cover 60 with the engagement portions 62 and 63,
and support the other end side thereof with the support legs 72 and
75. Therefore, a formed side table surface can be held stably,
thereby enabling sewing a large-sized work cloth easily.
[0061] Although the above example employs a planar portion having a
substantially laterally-placed U-shape as the shape of the
embroidery unit cover 60 in plan view, the present disclosure is
not limited thereto. Any other shape may be employed as the shape
of the embroidery unit cover 60 so long as the shape is the same as
the shape of the embroidery unit 30 in plan view and such that the
embroidery unit cover 60 can be placed over the embroidery unit 30
to cover the embroidery unit 30. Further, although the shapes,
numbers, and protruding positions of the engagement portions 62 and
63 that protrude from the peripheral wall portions 64 and 65 of the
embroidery unit cover 60 are specified in the example, the present
disclosure is not limited thereto. Any other shapes, numbers, and
protruding positions may be employed as the engagement portions 62
and 63 so long as they can be engaged with the female engagement
portions 20 and 21 of the sewing machine 1 and such that the
embroidery unit cover 60 can be held through the engagement.
Furthermore, although the shapes, axial supporting positions, and
operating postures of the support legs 72 and 75 provided on the
embroidery unit cover 60 are specified in the example, the present
disclosure is not limited thereto. Any other shapes, axial
supporting positions, and operating postures may be employed as the
side table so long as they can be supported when the embroidery
unit cover 60 is attached to the sewing machine 1 to be used as the
side table.
[0062] Although the embroidery unit cover 60 forms a side table in
the above example, the present disclosure is not limited thereto.
Alternatively, a side table may form the embroidery unit cover 60.
Although the shape of the side table is substantially U-shape in
plan view in the example, the present disclosure is not limited
thereto. Any other shape may be employed as the side table so long
as they can be attached to the sewing machine 1. Although the
shapes, numbers, and protruding positions of the engagement
portions that protrude from the peripheral wall of the side table
are specified in the example, the present disclosure is not limited
thereto. Any other shapes, numbers, and protruding positions may be
employed as the engagement portions can be engaged with the female
engagement portions 20 and 21 of the sewing machine 1 such that the
side table can be held through the engagement. Although the shapes,
numbers, and protruding portions of the locking portions that
protrude from the peripheral wall of the side table are specified
in the example, the present disclosure is not limited thereto. Any
other shapes, numbers, and protruding positions maybe employed as
far as the locking portions can be locked by the female locking
portions. Although the shapes, axial supporting positions, and
operating conditions of the support legs provided on-the side table
are specified in the example, the present disclosure is not limited
thereto; Any other shapes, axial supporting positions, and
operating postures may be employed as the side table so long as
they can be supported in a configuration such that the side table
is attached to the sewing machine.
[0063] As explained above, an embroidery unit cover of the present
disclosure includes a planar portion that forms a substantially
horizontal surface with a bed portion and a free arm portion of a
sewing machine, a peripheral wall portion that runs continuously
along a peripheral border of the planar portion and that extends
vertically downward from the planar portion, and a first engagement
portion that is provided to the peripheral wall portion. Therefore,
when the embroidery unit cover is attached to the sewing machine,
the embroidery unit cover forms a side table having the planar
portion as a table surface. Accordingly, a space for the embroidery
unit cover to be placed may be unnecessary, thereby enabling
effective utilization of a work space.
[0064] Further, a side table of the present disclosure includes a
planar portion that forms a substantially horizontal surface with a
bed portion and a free arm portion of a sewing machine, a
peripheral wall portion that runs continuously along a peripheral
border of the planar portion and that extends vertically downward
from the planar portion, a first engagement portion that is
provided to the peripheral wall portion, and a locking portion that
locks with an embroidery unit. Therefore, when the side table is
placed over the embroidery unit, the side table forms a cover that
prevents dust etc. from entering the embroidery unit.
[0065] Still further, a sewing machine of the present disclosure
includes an engagement portion that can be engaged with an
embroidery unit cover or a side table, on at least one of a bed
portion and a free arm portion. Therefore, the embroidery unit
cover or the side table can be attached to the sewing machine.
[0066] While various features have been described in conjunction
with the examples outlined above, various alternatives,
modifications, combinations, variations, and/or improvements of
those features and/or examples may be possible. Accordingly, the
examples, as set forth above, are intended to be illustrative.
Various changes may be made without departing from the broad spirit
and scope of the underlying principles.
