Description
Technical field
The disclosure relates to a kind of presser feet for Sewing machines, and the stage portion that described presser feet is pressed rapidoprint unexpectedly moves with the restriction rapidoprint.
Background technology
Shown in figure 32, the known presser feet 60 that is used for Sewing machines comprises bottom surface 61, preceding pressing part 64 and the back pressing part 67 with flat surfaces.Pin receiving opening 62 is formed on the middle part of bottom surface 61.Presser feet 60 is configured to make bottom surface 61 to press rapidoprint (fabric) reliably, thereby prevent that rapidoprint is along with the vertical movement of sewing needle vertically mobile (this vertical motion of rapidoprint is similar to sinuous flag, thereby be called " waving ") together.Such as, as shown in figure 33, sticking border to trousers or making under the situation of belt loop, when by Sewing machines the stage portion 10 that comprises three, nine and three foldings of fabric being made, preceding pressing part 64 is moved upward on the stage portion 10 by the rearward end 63 as supporting-point of bottom surface 61.Further, because rotating dog 4 is arranged near rearward end 63, so when current pressing part 64 was moved upward on the stage portion 10, rotating dog 4 moved up simultaneously.
So shown in Figure 34 and 35, the thickest of stage portion 10 is passed through rotating dog 4 subsequently near rotating dog 4 feedings, namely presser feet 60 is moved upward on the stage portion 10 and from this stage portion 10 and moves.When the thickest of stage portion 10 during near rotating dog 4 feedings, rapidoprint may be forced to move backward along the direction opposite with the direction of feed of rapidoprint because of presser bar pressure, and may moving up and suitably feeding suddenly because of rotating dog 4.
Further, as shown in figure 33, when current pressing part 64 touches stage portion 10, by the last corner of stage portion 10, the lower end 66 of stage portion 10 and the space 68 that back pressing part 67 has formed general triangular.Under this situation, presser feet 60 can't be pressed the rapidoprint in the space 68 reliably.Therefore, when sewing needle 6 runs through in the rapidoprint, because presser feet 60 can't be pressed rapidoprint reliably, so can not be formed uniformly wire loop.As a result, can take place such as sewing defectives such as wire jumpers.These sewing defectives can appear at presser feet 60 in a similar manner from the situation that stage portion 10 moves down (seeing Figure 35).
Disclosed known presser feet comprises the pressure foot that is attached to presser feet keeper lower end by rotating shaft in the mode that can rotate among the JP1991-65570U (hereinafter being called list of references 1).Recess is formed on the side of the bottom surface of pressure foot, thus be positioned at rotating shaft roughly under.
Further, disclosed presser feet for Sewing machines comprises preceding presser feet and the back presser feet of arranging along the direction of feed of rapidoprint among the JP1996-141251A (hereinafter being called list of references 2).Preceding presser feet and back presser feet are attached to the presser feet arm in the mode that can rotate.Between presser feet and the back presser feet, second helical spring was arranged between back presser feet and the presser feet arm before first helical spring was arranged in.Current presser feet is along away from the rotation of the direction of bed surface the time, and first helical spring presser feet backward applies bias force, thereby presser feet moves near bed surface before making.
In addition, JP1993-161771A discloses a kind of known fabric feed control device that is used for Sewing machines in (hereinafter being called list of references 3).The fabric feed control device comprises when the contact site that the front end of rapidoprint or stage portion approach with presser feet contacts, the sensor of the stage portion of detection rapidoprint (fabric).When detecting stage portion, sensor is sent to CPU with detection signal.Subsequently, CPU gives an order to reduce the pressure of presser feet; Thereby, increased the distance that moves horizontally of feed dog.
The presser feet of describing in the list of references 1 can be moved upward to easily by means of the recess of presser feet bottom surface on the stage portion of rapidoprint and from this stage portion and move.Yet, when recess along the length of the direction of feed of rapidoprint more in short-term, presser feet is difficult to be moved upward on the stage portion of rapidoprint because of the par of its bottom surface.When the length along direction of feed of recess is longer, be recessed into around the part of pin receiving opening.Therefore, presser feet can't prevent the rapidoprint vibration.In addition, when presser feet is moved upward to when moving on the stage portion of rapidoprint and from this stage portion, it can't flatten rapidoprint reliably and can't prevent the rapidoprint vibration.
In addition, according to the presser feet of describing in the list of references 2, include preceding presser feet separately and back presser feet, when under the situation under preceding presser feet moves from stage portion rapidoprint being carried out back stitching seam (feeding falls back), the rear end of preceding presser feet can not be moved upward on the stage portion again, thereby causes being involved in the end of a thread.Further, when presser feet was attached to Sewing machines, preceding presser feet was downward-sloping, thereby caused the user to be difficult to feeding rapidoprint under presser feet.In addition, the complex structure of presser feet and comprise more parts, thereby increased the manufacturing cost of presser feet.
In addition, according to the fabric feed control device of describing in the list of references 3, sensor detects the inclination angle of presser feet and detection signal is sent to CPU.Therefore, CPU handles detection signal and the detection signal that will handle exports the actuator of controlling foot pressure to and exports the actuator of controlling the fabric amount of feeding to.As a result, the feeding state is adjusted, thus the stage portion of feeding rapidoprint easily.The fabric control device comprises this sensor and actuator and thereby only is applied in the very expensive Sewing machines.Therefore, the fabric control device can't be applied in the Sewing machines of various patterns.
So need a kind of cheap presser feet that is used for Sewing machines, it can prevent from wire jumper occurring in the stage portion of rapidoprint, feeding rapidoprint suitably, and can be applied in the Sewing machines of various patterns.

Below in conjunction with Fig. 5 to 14 details of operation according to the presser feet 1 of first embodiment is described.
Fig. 5 illustrates the stage portion 10 of rapidoprint near the situation before presser feet 1 feeding.In Fig. 5, presser feet 1 is pressed rapidoprint (stage portion of its three foldings).The elastic force of the leaf spring 50 of limiting member 40 is set to definitely less than presser bar pressure.Therefore, as shown in Figure 5, leaf spring 50 strains also move up.Further, presser bar pressure is contained in the accommodation section 27 of main body 20 portion of crossing 42.In addition, because presser bar pressure will be crossed portion 42 by being pressed on the rapidoprint, so the part around pin receiving opening 33 of rapidoprint is pressed in press section 41 by axle 43.It is similar to the situation of making thin rapidoprint that this situation seems, therefore prevents wire jumper.
Fig. 6 illustrates presser feet 1 and begins to be moved upward to situation on the stage portion 10.The space 11 of general triangular is formed between presser feet 1 and the rapidoprint.At this moment, the waving of rapidoprint is subjected to being arranged in the restriction of elastic force (restoring force) of the leaf spring 50 of limiting member 40, thereby prevents from forming inhomogeneous wire loop.Further, when presser feet 1 is moved upward on the stage portion 10, prevent wire jumper.
Fig. 7 illustrates stage portion 10 and moves to the contact position that contacts with the top rake portion 23 of presser feet 1.In this structure, the top corner connection of stage portion 10 contacts the top rake portion 23 of main body 20, and presser bar pressure is not applied to the portion of crossing 42 of limiting member 40.Further, the elastic force of leaf spring 50 (restoring force) is contained in second accommodation section 28 of main body 20 press section 41.
The stage portion 10 that Fig. 8 illustrates rapidoprint is further near the situation of rotating dog 4 feedings.In this case, presser bar pressure is better than the elastic force of leaf spring 50, thereby makes leaf spring 50 strains.At this moment, the inclination alpha of presser feet 1 is compared with the angle of inclination beta of known presser feet 60 (seeing Figure 34) and has been reduced about 40%.Further, rotating dog 4 is littler by about 10% than the height h2 of the rotating dog 4 of known presser feet 60 (seeing Figure 34) from the height h1 that rapidoprint begins.Therefore, the resistance of rotating dog 4 (along the directive effect opposite with direction of feed) reduces to some extent, and described resistance produces under stage portion 10 moves to rotating dog 4 with respect to rapidoprint, and the load variations of presser bar pressure reduces to some extent; Therefore, the steady feeding of rapidoprint is with the below through presser feet 1.
The stage portion 10 that Fig. 9 illustrates rapidoprint move to rotating dog 4 under situation.In this case, presser bar pressure is applied to the whole zone of top rake portion 23 of the main body 20 of presser feet 1.Because the deep 25 as the top rake portion 23 of main body 20 and the flex point between the rear-inclined portion 24 is positioned to than rotating shaft 4 more backward, so the situation shown in Fig. 9 realizes because of lever principle.
Figure 10 illustrates the stage portion 10 of rapidoprint through the situation under the rotating dog 4.In this case, the last corner of stage portion 10 contacts with the rear-inclined portion 24 of main body 20.At this moment, the height of rotating dog 4 changes, but the amount that changes is very little; Therefore, the feeding of rapidoprint is not suppressed.
The terminal part that Figure 11 illustrates the stage portion 10 of rapidoprint moves to the roughly below of rotating dog 4.In this case, the space 11 of general triangular is formed on mode between stage portion 10 and the presser feet 1 and presser feet 1 to be moved upward on the stage portion 10 being seen mode identical.In addition, the restriction of the leaf spring 50 that is restricted member 40 of waving of rapidoprint; Therefore, suppress to occur wire jumper.
The rear end rake 29 that Figure 12 illustrates the main body 20 of presser feet 1 moves situation before from the stage portion 10 of rapidoprint.In this case, presser feet 1 moves from stage portion 10, the restriction of the leaf spring 50 that waving in the space 11 that the while rapidoprint forms between main body 20 and stage portion 10 is restricted member 40.At this moment, press section 41 does not contact with stage portion 10, and load is not applied on the press section 41.Further, presser bar pressure is contained in first accommodation section 27 of main body 20 portion of crossing 42.When under situation shown in Figure 12 rapidoprint being carried out back stitching seam (feeding falls back), presser feet 1 can be moved upward to easily on the stage portion 10 and from this stage portion 10 and move.
Figure 13 illustrates the situation that the rear end rake 29 of the main body 20 of presser feet 1 contacts with the stage portion 10 of rapidoprint.As seen in Figure 35, the not enough presser feet 60 in the downward inclination angle of known presser feet 60 is pressed rapidoprint.When feed dog moved below the needle plate surface, because presser bar pressure, the rear end rake 69 of known presser feet 60 made stage portion 10 move by force or suddenly along direction of feed.Therefore, the amount of feeding of rapidoprint increases.As a result, sewing needle 6 may bend because of moving by force or suddenly of rapidoprint.Simultaneously, according to the presser feet of describing in first embodiment 1, recess 31,32 has increased the inclination angle forward of main body 20, and the contact site 5 of the presser feet keeper 2 on the female portion 31,32 prevents main body 20 and is arranged in main body 20 conflicts.Further, rapidoprint is by the portion of crossing 42 of limiting member 40, by the presser bar pressure maintenance that is applied on the main body 20.As a result, suppressing rapidoprint moves by force or suddenly along direction of feed.
Figure 14 illustrates presser feet 1 and moves later situation from the stage portion 10 of rapidoprint.In Figure 14, the leaf spring 50 of limiting member 40 is to be same as the mode strain shown in Fig. 5 and to move up.In this case, presser bar pressure is contained in first accommodation section 27 portion of crossing 42.
According to the presser feet 1 of first embodiment, limiting member 40 is provided with the leaf spring of giving prominence to from the bottom surface 21 of main body 20 50.Therefore, when stage portion 10 moved to the contact position that contacts with the front portion of presser feet 1, the space 11 of general triangular was formed between stage portion 10 and the presser feet 1.At this moment, leaf spring 50 is pressed rapidoprint with the movement of restriction rapidoprint.Therefore, wire loop is formed uniformly, and prevents wire jumper.When presser feet 1 was moved upward on the stage portion 10 and moves from this stage portion 10, this effect of leaf spring 50 was effective.Further, presser feet 1 is by forming such as the parts of main body 20 with two types of limiting member 40 grades that comprise leaf spring 50; Therefore, material and the manufacture process of presser feet 1 can easily be provided.In addition, when presser feet 1 was applied on the Sewing machines, the body of Sewing machines need not application specific architecture.Therefore, presser feet 1 can be applied to traditional Sewing machines and at random disposed thereon.
In addition, limiting member 40 and leaf spring 50 are all by the resin formula member that forms to form as one.Therefore, limiting member 40 can and be attached to presser feet 1 easily with the low cost manufacturing.
In addition, spring member 50 is to press rapidoprint and thereby make the elastic component of limiting member 40 elastic biasings by means of elastic force.So limiting member 40 need not be used to the biasing member (such as compression helical spring) that leaf spring 50 is given prominence to from the bottom surface 21 of the main body 20 of presser feet 1.As a result, make the part count of presser feet 1 minimized.
Under pin receiving opening 33 was positioned situation between the leaf spring 50, leaf spring 50 was arranged in the side of limiting member 40.Therefore, the motion of the rapidoprint around the pin receiving opening 33 is subjected to the restriction of the dotted line that limited by leaf spring 50; Therefore, wire loop is formed uniformly.
In addition, the bottom surface 21 of the main body 20 of presser feet 1 is configured so that the deep 25 between top rake portion 23 and the rear-inclined portion 24 is positioned to than rotating dog 4 more backward.Therefore, such as, in (under the situation of the jeans of sticking border) under the situation that the stage portion of thick rapidoprint is made, when presser feet 1 is moved upward on the stage portion, therefore the inclination angle of presser feet 1 reduces to some extent, has reduced presser bar pressure transmission moving up to the rotating dog 4 of rapidoprint.Further, though when stage portion 10 be plugged on rotating dog 4 under the time, so because the position rotating dog 4 in deep 25 need not to move up to be higher than the thickness of the stage portion 10 of rapidoprint; Therefore, rapidoprint is fed into the below of presser feet 1 reposefully.In addition, after direction of feed process rotating dog 4, the inclination angle of presser feet 1 makes presses stage portion 10 along the shape of top rake portion 23 and rear-inclined portion 24 in stage portion 10.Therefore, bottom surface 21 be positioned to be moved upward to easily on the stage portion 10 than rotating dog 4 rear portion more backward.Moving up of rotating dog 4 gradually changes, thereby makes presser feet 1 can be moved upward to easily on the stage portion 10 and from this stage portion 10 to move.In addition, top rake portion 23 and rear-inclined portion 24 form and extend to pin receiving opening 33.Therefore, when Sewing machines was made thin rapidoprint, main body 20 possibilities of presser feet 1 can't be by the part around pin receiving opening 33 of ironed rapidoprint.Yet main body 20 is become one with limiting member 40; Thereby limiting member 40 is by the part around pin receiving opening 33 of ironed rapidoprint.As a result, suppress to occur wire jumper.
Second embodiment for the presser feet 101 of Sewing machines is described below.Figure 15 A is the stereogram of the presser feet 101 seen from the top.Figure 15 B is the stereogram of the presser feet 101 seen from the below.Presser feet 101 mainly comprises limiting member 140, compression helical spring 151 (seeing Figure 18) and the torsion-coil spring 152 (seeing Figure 18) that main body 120, restriction rapidoprint wave.

The bottom surface 121 of the main body 120 of presser feet 101 comprises frontal plane 122a, back plane 122b, top rake portion (rake) 123 and rear-inclined portion (rake) 124.The deep 125a of reality between top rake portion 123 and the rear-inclined portion 124 is positioned to than rotating dog 104 more backward.Pin receiving opening 133 is formed in the approximate mid-section of main body 120.Sewing needle 106 (seeing Figure 19) transfixion pin receiving opening 133.Accommodation section 128 is arranged on the bottom surface 121.The restriction portion 141 (seeing Figure 17) of accommodation section 128 ccontaining limiting members 140 (seeing Figure 17).Restriction portion 141 as one man is contained in the accommodation section 128 with the rotation of limiting member 140, thereby flatly is connected to the bottom surface 121 of the main body 120 of presser feet 101.Further, prevent that first and second recess 131 and 132 that main body 120 contacts the contact site 105 of presser feet keepers 102 is formed on the bottom surface 121.Hole 126 is formed on the side of main body 120.Axle 143 (the seeing Figure 17) of limiting member 140 are plugged in the hole 126.In addition, wherein keep the recess 156 of compression helical spring 151 (seeing Figure 18) and wherein keep the fit 157 of torsion-coil spring 152 (seeing Figure 18) to be arranged in the main body 20 of presser feet 101.
Figure 17 A is the vertical view that includes the limiting member 140 of restriction portion 141.Figure 17 B is the side view of limiting member 140.Figure 17 C is the upward view of limiting member 140.Figure 17 D is along the line 17D-17D of Figure 17 cutaway view that cut open, limiting member 140.Limiting member 140 comprises restriction portion 141, rotation banking pin 142 and helical spring maintaining part 150.Axle 143 is arranged in the inside of the side of limiting member 140.Under the situation in limiting member 140 is contained in the accommodation section 128 of main body 120, the cross section of limiting member 140 forms consistent with the shape of top rake portion 123 and rear-inclined portion 124.In this case, the deep 125a of reality is arranged on limiting member 141 places.
Figure 18 A is the vertical view of the assembling situation of presser feet 101, and wherein limiting member 140 is attached to main body 120.Figure 18 B is the side view of the assembling situation of presser feet 101.Figure 18 C is the upward view of the assembling situation of presser feet 101.Figure 18 D is the cutaway view along the line 18D-18D assembling situation that cut open, presser feet 101 of Figure 18 A.Axle 143 is assemblied in the hole 126, thereby limiting member 140 is attached to movably the main body 120 of presser feet 101.Further, the permission rotating range of limiting member 140 is determined by the limiting surface 127 of rotation banking pin 142 and main body 120.In addition, as seen, the load around axle 143, effect along clockwise direction of compression helical spring 151 is applied to limiting member 140 constantly in Figure 18 B and 18D.The direction that clockwise direction is given prominence to downwards from the bottom surface 121 of the main body 120 of presser feet 101 corresponding to the restriction portion 141 of limiting member 140.So the aforementioned effect of compression helical spring 151 prevents that rapidoprint from waving.In addition, torsion-coil spring 152, make whole presser feet 101 with respect to spring keep surperficial 105a (seeing Figure 19), around rotating dog 104 backward, downward-sloping load is applied to presser feet 101.So, be moved upward at presser feet 101 under the situation on the stage portion 110 of rapidoprint, when presser feet 101 not backward, when downward-sloping, will prevent feeding fault (being suitably feeding of rapidoprint).As a result, presser feet 101 moves on the stage portion 110 easily.
Below with reference to the details of operation of Figure 19 to 28 description according to the presser feet 101 of second embodiment.
The stage portion 110 that Figure 19 illustrates rapidoprint moves to the contact position situation before that contacts with presser feet 101.In Figure 19, presser feet 101 is pressed rapidoprint (stage portion 110 of its three foldings).The elastic force (restoring force) that load is applied to the compression helical spring 151 of limiting member 140 is set to determine less than presser bar pressure.Therefore, compression helical spring 151 can not be resisted presser bar pressure, thereby make limiting member 140 press the part around the pin receiving opening 133 of being positioned at of rapidoprint around the restriction portion 141 of axle 143, rotation, and the preceding flat 122a of portion in the counterclockwise direction, the back flat 122b of portion and limiting member 140.It is similar to the situation of making thin rapidoprint that this situation seems.So the part around pin receiving opening 133 of ironed rapidoprint is pressed by the restriction portion 141 of the preceding flat 122a of portion, the flat 122b of portion in back and limiting member 140, thereby prevents wire jumper.
Figure 20 illustrates presser feet 101 and begins to be moved upward to situation on the stage portion 110.The space 111 of general triangular is formed between presser feet 101 and the rapidoprint.At this moment, the effect of compression helical spring 151 makes waving of rapidoprint be restricted the restriction of the restriction portion 141 of member 140.Therefore, under presser feet 101 is moved upward to situation on the stage portion 110, prevent from forming wire loop unevenly and wire jumper occurring.
Figure 21 illustrates the situation that stage portion 110 moves to the contact position that contacts with the top rake portion 123 of presser feet 101.In this case, the last corner of stage portion 110 contacts with the top rake portion 123 of main body 120, and limiting member 140 is further rotated because of the effect of compression helical spring 151, so restriction portion 141 prevents that rapidoprint from waving.At this moment, the restriction portion 141 of limiting member 140 is outstanding fully downwards from the bottom surface 121 of the main body 120 of presser feet 101.When the overhang of restriction portion 141 was very big, restriction portion 141 can conflict with sewing needle 106.Rotation banking pin 142 is arranged on the limiting member 140.Rotation banking pin 142 is adjusted the overhang that contacts with limiting surface 127 on the main body 120 that is arranged in presser feet 101, thereby prevents from conflicting between restriction portion 141 and the sewing needle 106.
The stage portion 110 that Figure 22 illustrates rapidoprint is further near the situation of rotating dog 104 feedings.In this case, move along stage portion 110 bottom 153 of the side of limiting member 140; Thereby limiting member 140 is around axle 143, rotation in the counterclockwise direction, and restriction portion 141 is contained in the accommodation section 128 of main body 120.At this moment, the inclination alpha of presser feet 101 is compared with the angle of inclination beta of known presser feet 60 (seeing Figure 34) and has been reduced about 40%.Further, rotating dog 104 is littler by about 10% than the height h2 of the rotating dog 4 of known presser feet 60 from the height h1 that rapidoprint begins.Therefore, the resistance of rotating dog 104 (along the directive effect opposite with direction of feed) reduces to some extent, and described resistance produces under stage portion 110 moves to rotating dog 104 with respect to rapidoprint, and the load variations of presser bar pressure reduces to some extent; Therefore, rapidoprint steadily is fed into the below of presser feet 101.
The stage portion 110 that Figure 23 illustrates rapidoprint move to rotating dog 104 under situation.In this case, presser bar pressure is applied to the whole zone of the top rake portion 123 of main body 120.Because deep 125a is positioned to than rotating shaft 104 more backward as the reality of the top rake portion 123 of main body 120 and the flex point between the rear-inclined portion 124, so the situation shown in Figure 23 realizes because of lever principle.
Figure 24 illustrates the stage portion 110 of rapidoprint through the situation under the rotating dog 104.In this case, the last corner of stage portion 110 contacts with the rear-inclined portion 124 of main body 120.At this moment, the height of rotating dog 104 changes, but the amount that changes is very little; Therefore, the feeding of rapidoprint is not suppressed.
The back flat 122b of portion that Figure 25 illustrates main body 120 moves the situation of getting off from the stage portion 110 of rapidoprint.Presser feet 101 moves from stage portion 110, the restriction of the restriction portion 141 that waving in the space 111 of the general triangular that the while rapidoprint forms between stage portion 110 and main body 120 is restricted member 140.Therefore, when under situation shown in Figure 25 rapidoprint being carried out back stitching seam (feeding falls back), the rearward end 155 of limiting member 140 makes presser feet 101 to be moved upward to easily on the stage portion 10.
Figure 26 illustrates the situation that the rear end rake 129 of the main body 120 of presser feet 101 contacts with the stage portion 110 of rapidoprint.Known presser feet 60 shown in Figure 32 can't be pressed rapidoprint reliably, because as shown in figure 35, conflicting between the contact site 2a of presser feet keeper 2 and the presser feet 60 makes that the downward inclination angle of known presser feet 60 is not enough.Such as, when feed dog moved below the needle plate surface, by means of presser bar pressure, the rear end rake 69 of known presser feet 60 made stage portion 10 move by force or suddenly along direction of feed; Therefore, the amount of feeding of rapidoprint increases.As a result, sewing needle 6 may bend along moving by force of direction of feed because of rapidoprint.Simultaneously, according to the presser feet of describing in second embodiment 101, recess 131,132 has increased the inclination angle forward of main body 120, and the female portion 131,132 prevents that main body 120 from conflicting with contact site 105 on the presser feet keeper 102 that is arranged in main body 120.Further, rapidoprint is kept by the presser bar pressure in the curved guide portion 154 that is applied to main body 120 (Figure 16 B and 16D).As a result, suppress rapidoprint along direction of feed feeding by force.
Figure 27 illustrates presser feet 101 and moves later situation from the stage portion 110 of rapidoprint.In this case, rapidoprint is pressed by limiting member 140, makes the part around pin receiving opening 133 of rapidoprint be pressed by the preceding flat 122a of portion, the flat 122b of portion in back and restriction portion 141.It is similar to the situation of making thin rapidoprint that this situation seems.So the part around pin receiving opening 133 of thin rapidoprint is pressed by the restriction portion 141 of the preceding flat 122a of portion, the flat 122b of portion in back and limiting member 140, thereby prevents wire jumper.
According to the presser feet 101 of second embodiment, limiting member 140 is provided with the protuberance of giving prominence to from the bottom surface 121 of main body 120 141 downwards.Therefore, when stage portion 110 moved to the contact position that contacts with the front portion of presser feet 101, the space 111 of general triangular was formed between stage portion 110 and the presser feet 101.At this moment, rapidoprint is pressed with the movement of restriction rapidoprint by restriction portion 141.Therefore, wire loop is formed uniformly, and prevents wire jumper.When presser feet 101 was moved upward on the stage portion 110 and moves from this stage portion 110, this effect of restriction portion 141 was visible.Further, presser feet 101 is by such as main body 120 with comprise that the parts of four types of limiting member 140, compression helical spring 151 and the torsion-coil springs 152 etc. of restriction portion 141 form, and material and the manufacture process of presser feet 101 can easily be provided.In addition, when presser feet 101 was applied on the Sewing machines, the body of Sewing machines need not application specific architecture.Therefore, presser feet 101 can be applied to traditional Sewing machines and at random disposed thereon.
In addition, limiting member 140 and restriction portion 141 are integrally moulded by resin.Therefore, limiting member 140 can be easily with the low cost manufacturing and be attached to presser feet 101 easily.
In addition, the bottom surface 121 of the main body 120 of presser feet 101 is configured so that the deep 125a between top rake portion 123 and the rear-inclined portion 124 is positioned to than rotating dog 104 more backward.Therefore, such as, in (under the situation of the jeans of sticking border) under the situation that the stage portion of thick rapidoprint is made, when presser feet 101 is moved upward on the stage portion, therefore the inclination angle of presser feet 101 reduces to some extent, has reduced presser bar pressure transmission moving up to the rotating dog 104 of rapidoprint.Further, though when stage portion 110 be plugged on rotating dog 104 under the time, rotating dog 104 need not to move up to be higher than the thickness of the stage portion 110 of rapidoprint, and rapidoprint is fed into the below of presser feet 101 reposefully.In addition, the inclination angle of presser feet 101 makes and presses stage portion 110 along the shape of top rake portion 123 and rear-inclined portion 124.Therefore, bottom surface 121 be positioned to be moved upward to easily on the stage portion 110 than rotating dog 104 rear portion more backward.Moving up of rotating dog 104 gradually changes; Thereby presser feet 101 can be moved upward to easily on the stage portion 110 and from this stage portion 110 and move.Top rake portion 123 and rear-inclined portion 124 form and extend to pin receiving opening 133.Therefore, under the situation that thin rapidoprint is made, main body 120 possibilities of presser feet 101 can't be by the part around pin receiving opening 133 of ironed rapidoprint.Yet main body 120 is become one with limiting member 140; Thereby limiting member 140 is by the part around pin receiving opening 133 of ironed rapidoprint, thereby wire jumper appears in inhibition.
Figure 28 A and Figure 28 B illustrate the 3rd embodiment, and described the 3rd embodiment is the modified example according to the presser feet 101 of second embodiment.Illustrated presser feet 101 comprises that it is attached with the limiting member 140 that replenishes limiting member 158 in Figure 28 A and 28B.Replenishing limiting member 158 has along direction of feed and is positioned at arm 158a and 158b in the pin receiving opening 133.Figure 28 A and 28B are respectively vertical view and the side views according to the presser feet 101 of the 3rd embodiment.Figure 29 illustrates the situation that the par of rapidoprint is made.Figure 30 illustrates the situation on the stage portion 110 that presser feet 101 according to the 3rd embodiment is moved upward to rapidoprint.Figure 31 illustrates presser feet 101 according to the 3rd embodiment and moves the situation of getting off from stage portion 110.
Replenish limiting member 158 and be attached to limiting member 140, thereby along direction of feed rapidoprint is remained in the pin receiving opening 133.Therefore, before moving down and enter pin receiving opening 133, sewing needle 106 prevents that rapidoprint from waving.As a result, wire loop is able to evenly and forms effectively.
