Fig. 5 represents to utilize the 1st spring 46 to make secondary bar 4 drop to the below and is set in the state of the position P1 that can embroider.When secondary bar 4 is set in the position P1 that can embroider, the active force that utilizes holddown spring 34 downwards (arrow D direction) to the bottom 33e application of force of presser feet 33, with bottom 33e by being pressed on the needle plate 23.Thereby, utilize the bottom 33e of presser feet 33 and needle plate 23 to grip cloth (being sewed thing).As shown in Figure 5, when secondary bar 4 is set in the position P1 that can embroider, between the top ends 39c of the cam surface 42 of secondary bar 4 and motion arm 39, produce gap size A3 (with reference to (b) of Fig. 5).Thereby, top ends 39c be positioned at cam surface 42 the top and with cam surface 42 noncontacts.Like this when secondary bar 4 is positioned at the position P1 (with reference to (b) of Fig. 5) that can embroider, between the upper end 31au of the top ends 39c of motion arm 39 and slotted hole 31a, form distance W 1 (with reference to (b) of Fig. 5).Therefore, motion arm 39 can further rise along the slotted hole 31a of maintaining part 31, so presser feet 33 can further relatively rise.As shown in Figure 5, when secondary bar 4 is set in the position P1 that can embroider, when Sewing machines starts, same with prior art, during 1 cycle of the knee-action of shank 1 in, presser feet 33 rises 1 time, the power of pressing the cloth on the eedle presser 23 disappears, so the user can embroider at cloth on one side, the cloth on the needle plate 23 is moved freely, the sewing that can embroider etc.
As shown in Figure 5, when secondary bar 4 was set in the position P1 that can embroider, if the lifting amount of presser feet 33 is larger when the sewing of embroidering etc., then presser feet 33 was along the significantly lifting of arrow H direction, so may allow the user feel to offend the eye.In this, adopt present embodiment, as shown in Figure 1, along the lifting of arrow H direction, motion arm 39 is positioned at the top dead centre position apart from this top dead centre small quantity Δ H (for example 0.2 millimeter～2.0 millimeters) on the lower than needle fixation device 11 to needle fixation device 11 between the lower dead center of this needle fixation device 11 and top dead centre.Therefore, though when embroidery needle fixation device 11 rise along short transverse (arrow H direction) with shank 1, it also is the small amount that is equivalent to Δ H that the lifting amount of the motion arm 39 that is lifted by needle fixation device 11 is compared with the lifting amount of needle fixation device 11.And then the amount of lifting of presser feet 33 of embroidery casting die 3 also is small amount, can not allow the user what feels to have offend the eye.In addition, when needle fixation device 11 dropped to lower dead center, motion arm 39 also descended, but presser feet 33 and needle plate 23 butts can not descend more than the Δ H.
In addition, when the sewing of embroidering etc., as intelligible according to Fig. 1, shank 1 between the top dead centre of this shank 1 and lower dead center along the lifting of arrow H direction.Equally, the needle fixation device 11 that remains in shank 1 for locking pin 10 is lifting between the top dead centre of this needle fixation device 11 and lower dead center also.Even needle fixation device 11 has dropped to the lower dead center of this needle fixation device 11, needle fixation device 11 also not can with needle plate 23 on presser feet 33 collision of embroidery casting die 3.In addition, needle fixation device 11 comprises needle fixation device main body 11a and needle fixation device screw 11c (with reference to Fig. 1).
Make position P1 that secondary bar 4 self energys embroider further upward during (arrow B direction) angle of elevation B1 (with reference to (b) of Fig. 6) with finger from state shown in Figure 5 the user, secondary bar 4 is in temporary transient fixed position P2.In this process, motion arm 39 moves and is lifted by upwards (arrow U direction) along the cam surface 42a of secondary bar 4, and the top ends 39c of motion arm 39 rises along slotted hole 31a.As a result, with motion arm 39 in linkage the presser feet 33 of lifting also rise along arrow U direction, the top ends 39c of motion arm 39 engages with holddown groove 44 and temporarily is fixed in this holddown groove 44 (with reference to (b) of Fig. 6).That is, secondary bar 4 is in temporary transient fixed position P2.In this case, the bottom 33e of presser feet 33 temporarily is fixed on its 1st height and position M1 (with reference to (b) of Fig. 6).
Be under the state of temporary transient fixed position P2 at secondary bar 4 like this, engaging size B4 (with reference to (b) of Fig. 6) is equivalent to the top ends 39c of motion arm 39 and the amount of engaging of the groove bottom of holddown groove 44.Be under the state of temporary transient fixed position P2 at secondary bar 4 like this, even if user's finger has left the operating portion 45 of secondary bar 4, regardless of the active force of the 1st spring 46 and holddown spring 34, secondary bar 4 is not (arrow F direction) rotation downwards also.Therefore, secondary bar 4 temporarily is fixed on the upward temporary transient fixed position P2 behind the rotational angle B1 of position P1 that self energy embroiders.
In the process that motion arm 39 lifts in the above described manner, overcome active force towards the arrow D of holddown spring 34 direction with motion arm 39 integrated last items 35 and presser feet 33, and rise and suspend from needle plate 23 along arrow U direction.Thus, the bottom 33e of presser feet 33 is in the 1st height and position M1 (with reference to Fig. 6), forms gap size B5 (with reference to Fig. 6) between the bottom of presser feet 33 33e and needle plate 23.When secondary bar 4 is set in temporary transient fixed position P2, form gap size B5 like this.Therefore, lift secondary bar 4, presser feet 33 even the user need not point, the embroidery frame of the cloth of the embroidery usefulness that stretches tight is being passed through arbitrarily below the 33e of the bottom of presser feet 33 on the needle plate 23.Thereby, can carry out simply to Sewing machines support configuration embroidery frame.
In other words, as shown in Figure 6, be under the state of temporary transient fixed position P2 at secondary bar 4, even user's finger has left the operating portion 45 of the secondary bar 4 of embroidery casting die 3, because the top ends 39c of motion arm 39 engages with holddown groove 44 and temporarily is fixed, so not (arrow F direction) rotation downwards of secondary bar 4.In addition, between the bottom of presser feet 33 33e and needle plate 23, be formed with gap size B5.Therefore, the operation that embroidery casting die 3 is installed on the bottom 13d of depression bar 13 or dismantles this embroidery casting die 3 from the bottom of depression bar 13 becomes easy.As shown in Figure 6, during the handling operation of the casting die 3 of embroidering under the state of temporarily having fixed secondary bar 4, operability is best, the handling operation of the casting die 3 of preferably embroidering under this state.
In addition, sometimes also use the embroidery frame with the above height dimension of gap size B5.In this case, the operating portion 45 that makes secondary bar 4 with finger as the user is from state shown in Figure 6 upward (arrow B direction) when further rotating, namely when the position P1 that can embroider from secondary bar 4 lifts secondary bar 4 with angle C1, further lift motion arm 39 along the cam surface 42b of secondary bar 4.In this case, also rise along arrow U direction in linkage with motion arm 39 integrated last items 35 and presser feet 33.Therefore, shown in Fig. 7 (a), (b), presser feet 33 further suspends and is in the 2nd height and position M2 from needle plate 23.In this case, between the bottom of presser feet 33 33e and needle plate 23, form broader gap size C2 (C2＞B5).Like this owing to forming broad gap size C2, so even higher embroidery frame also can make this embroidery frame pass through on the needle plate 23, also can easily carry out the configuration of thicker embroidery frame below the 33e of the bottom of presser feet 33.
But as shown in Figure 7, be at presser feet 33 under the state of the 2nd height and position M2, motion arm 39 does not engage with holddown groove 44.Therefore, when user's finger leaves the operating portion 45 of secondary bar 4 of embroidery casting die 3, secondary bar 4 is because of the active force of the 1st spring 46 (arrow F direction) automatic rotating downwards, secondary bar 4 is in temporary transient fixed position P2 (with reference to (b) of Fig. 6), and presser feet 33 is outstanding downwards because of the active force of holddown spring 34.
The reason that makes in the above described manner secondary bar 4 turn back to temporary transient fixed position P2 is downwards seen following.That is, even descend and when having arrived lower dead center at shank 1, contacting of also can avoid embroidering casting die 3 and the needle fixation device 11 that remains in shank 1 avoided damaging.Thereby, in advance gap size B5 is set as following size: even descend and when having arrived lower dead center at shank 1, also can avoid contacting of needle fixation device 11 and the casting die 3 of embroidering.Like this under state shown in Figure 7, because motion arm 39 does not engage with holddown groove 44, so when user's finger leaves operating portion 45, the presser feet 33 of the secondary bar 4 of embroidery casting die 3, secondary bar 4 turns back to the state of Fig. 6 because of active force (arrow F direction) rotation downwards of the 1st spring 46.Therefore, even if user's mistake is started Sewing machines and shank 1 is descended, the bottom 33e of presser feet 33 also can not contact with the needle fixation device 11 that is installed on shank 1, can avoid the needle fixation device 11 that is caused by contact, the damage of presser feet 33.
Adopt present embodiment, carry out the user in the situation of preparation of the embroidery such as free-hand embroidery, as mentioned above, 14 remain on the 2nd grade of S2 and depression bar 13 is set under the 2nd grade the state in that casting die is argued for the sake of arguing, utilize erecting tools 30 (with reference to Fig. 1) casting die 3 of will embroidering to be installed on the bottom 13d of depression bar 13.Thus, become state shown in Figure 6 or state shown in Figure 7.Under state shown in Figure 6, owing between the bottom of presser feet 33 33e and needle plate 23, be formed with gap size B5, so can make embroidery frame between presser feet 33 and needle plate 23 by being configured, when embroidery frame by after make secondary bar 4 when temporary transient fixed position P2 descend with angle B 1 along arrow F direction, secondary bar 4 is in the position P1 (with reference to Fig. 5) that can embroider, and can embroider.
In addition, under state shown in Figure 7, owing between the bottom of presser feet 33 33e and needle plate 23, be formed with broader gap size C2 (C2＞B5), so can make higher embroidery frame between presser feet 33 and needle plate 23 by being configured, therefore when when embroidery frame makes secondary bar 4 descend along arrow F direction by rear user, the position P1 (with reference to Fig. 5) that secondary bar 4 is in can embroider can embroider.
In addition, in user's actual operation, preferably envision user error and tackle in advance.In actual operation, expect that the user is not used in the secondary bar 4 that embroidery casting die 3 descends and descends, but operate because of carelessness raising wire 14 and possibility that this raising wire 14 is descended.(a), (b) of Fig. 8 represent this situation.Fig. 8 (a) expression user makes to argue for the sake of arguing on the casting die and 14 rotates with angle D1 and mistake drops to the state of the 1st grade of S1 from the 2nd grade of S2.Under this state, along with arguing for the sake of arguing 14 operation on the casting die, depression bar 13 also has a little to descend, and the presser feet 33 of the casting die 3 of correspondingly embroidering also descends.But shown in Fig. 8 (a), the bottom 33e of presser feet 33 not with needle plate 23 butts, between presser feet 33 and needle plate 23, be formed with gap size D5 (D5＜B5).Therefore, can not produce the power that the top ends 39c that makes motion arm 39 breaks away from holddown groove 44, so the state constant (with reference to (a) of Fig. 8) that motion arm 39 maintenances engage with holddown groove 44.
With respect to this, Fig. 8 (b) expression user makes to argue for the sake of arguing on the casting die and 14 argues for the sake of arguing that 14 the 2nd grade of S2 rotates with angle E1 and mistake drops to the state of the 0th grade of S0 from this casting die.Under this state, 14 the operations linkage ground, below of arguing for the sake of arguing on depression bar 13 and the casting die descends a lot, and the bottom 33e of presser feet 33 and needle plate 23 butts relatively lift along arrow U direction so bottom 33e overcomes the active force ground of holddown spring 34 accordingly.And then presser feet 33, last item 35 and motion arm 39 are relatively lifted along arrow U direction with respect to casting die retainer 31.As a result, the top ends 39c of motion arm 39 breaks away from holddown groove 44, near the upper end 31au (with reference to (b) of Fig. 8) of slotted hole 31a.The amount of lifting of this moment is larger than the engaging size B4 of motion arm shown in Figure 6 39, so the top ends 39c of motion arm 39 breaks away from the holddown groove 44 of cam surface 42 as mentioned above.Like this when motion arm 39 breaks away from holddown groove 44, under the effect of the active force of the 1st spring 46 and holddown spring 34, secondary bar 4 automatically downwards (arrow F direction) rotates and automatically switches to the position P1 (with reference to (b) of Fig. 8) that can embroider, and presser feet 33 is outstanding downwards.Therefore, when making to argue for the sake of arguing on the casting die again, the user 14 is back to the 2nd grade of S2 (owing to be the embroidery pattern, so the tension force of upper thread is effective) time, depression bar 13 rises to the 2nd grade along arrow U direction, automatically become state shown in Figure 5 (state that can embroider), so the user can embroider immediately.
As mentioned above, adopt present embodiment, in the situation of the embroidery of carrying out free-hand embroidery etc., as preparation, making argues for the sake of arguing on the casting die 14 carries out rotating operation and becomes and can not make depression bar land the state of temporarily fixing this depression bar 13 for 13 times.This be because: in this Sewing machines, as mentioned above when the state that depression bar 13 temporarily is fixed on the 2nd grade, set the embroidery pattern.Under the state of the height and position of temporarily having fixed in the above described manner depression bar 13, the user can be installed on the bottom 13d of depression bar 13 with the manual operations casting die 3 of will embroidering.
In this case, the motion arm 39 of embroidery casting die 3 engages with the holddown groove 44 of the cam surface 42 of secondary bar 4 and temporarily is fixed in this holddown groove 44.When at this state, presser feet 33 overcomes the active force ground of holddown spring 34 and holddown spring 34 to casting die retainer 31 side shiftings.As a result, the height dimension HA (with reference to Fig. 6) of embroidery casting die 3 dwindles.In this case, stop the bottom 33e of presser feet 33 significantly mobile highlightedly from casting die retainer 31 because of the active force of holddown spring 34.Therefore, installing and during dismounting embroidery casting die 3, can cancel the user and make the presser feet 33 of embroidery casting die 3 move to casting die retainer 31 sides with manual operations and the operation of dwindling the height dimension HA of embroidery casting die 3.Therefore, the free operant of user's hand can be guaranteed, operability can be improved.
In addition, temporarily fixed as long as the holddown groove of the motion arm 39 of embroidery casting die 3 and secondary bar 4 44 is chimeric, then freely rotating of secondary bar 4 also stoped, so can further improve operability.When the holddown groove 44 that further makes motion arm 39 with the cam surface 42 of secondary bar 4 engages and temporarily is fixed in this holddown groove 44, as understanding according to Fig. 6 (b), secondary bar 4 is moved upward in the mode of separating with needle plate 23, has increased the operating portion 45 of secondary bar 4 and the space HE of needle plate 23.Therefore, can be with better operability, easily the casting die 3 of will embroidering is installed on depression bar 13.
In addition, be installed under the state of depression bar 13 at user's casting die 3 of will embroidering, shown in Fig. 6 (a), (b), presser feet 33 maintains the 2nd height and position M2, also keeps the gap size B5 between presser feet 33 and the needle plate 23.Therefore, also can save the user and make the presser feet 33 that is installed on depression bar 13 from the trouble that needle plate 23 rises, make embroidery frame immediately by gap size B5, it is easy that the configuration of embroidery frame also becomes.On this aspect, also can further improve operability.If higher embroidery frame then as mentioned above, when secondary bar 4 is rotated upward, can form broader gap size C2 (with reference to Fig. 7).
And; adopt present embodiment, because embroidery casting die 3 has the transparent cover wall 33h that faces mutually with the user who carries out the Sewing machines operation, so when the sewing of embroidering etc.; the finger mistake that can suppress the user contacts with pin 10, improves the protectiveness to the user.In addition, even in the situation that pin fractures in the embroidery process, also can improve block with respect to the pin that disperses after fractureing, the pin that also can utilize cover wall 33h to suppress to fracture disperses to user's side.Also can be shown in patent documentation 3 at the support side mounting cup wall 33h of Sewing machines, but in this case, the installation exercise of the casting die 3 of should embroidering covers the installation exercise of wall 33h again.But the employing present embodiment, transparent cover wall 33h is integrated with embroidery casting die 3 as mentioned above, so when the casting die 3 of will embroidering is installed on the bottom 13d of depression bar 13, can automatically not install and use the transparent cover wall 33h that the person protects usefulness, good operability.
In addition, as mentioned above, adopt present embodiment, even needle fixation device 11 has carried out lifting with shank 1 along short transverse (arrow H direction) when embroidery as mentioned above, it also is the small amount that is equivalent to Δ H that the amount of lifting of the embroidery casting die 3 that is lifted by needle fixation device 11 is compared with the lifting amount of needle fixation device 11, the lifting amount of cover wall 33h also is small, can not allow the user feel to offend the eye.Therefore, can increase the size of cover wall 33h, on this aspect, also can improve the protectiveness to the user.
Other
Adopt above-mentioned embodiment, utilizing erecting tools will embroider casting die 3 when being installed on the bottom of depression bar 13, depression bar 13 rises to the 2nd grade, but the present invention is not limited thereto, and depression bar 13 also can rise to the 1st grade.Holddown spring 34 is helical springs, but is turned round other springs such as helical spring and leaf spring.Presser feet 33 has transparent cover wall 33h, but presser feet 33 also can not have cover wall 33h.Adopt above-mentioned embodiment, can utilize argue for the sake of arguing on the casting die 14 with depression bar 13 stationarity ground temporarily be fixed on the 0th grade (tension force of facial suture is effective) as common sewing position, than on the 0th grade of top side the 1st grade (tension force of facial suture is invalid) and the position than the 1st grade of top side the 2nd grade (tension force of facial suture is effective).But the present invention is not limited to above-mentioned this Sewing machines, so long as the Sewing machines that depression bar 13 temporarily can be fixed on the height and position of regulation for embroidery casting die 3 is installed gets final product, also can be other Sewing machiness in a word.It is grand that motion arm 39 utilizes the needle fixation device 11 of shank 1 to rise, but also can not utilize needle fixation device 11 to carry out lifting, but utilize shank 1 direct lifting.The present invention not only is defined in the embodiment that represents in above-mentioned explanation and the accompanying drawing, can suitably change in the scope that does not break away from purport and implements the present invention.
