Base end part in above-mentioned adjustment screw 20 is provided with operation knob 25.In this embodiment, operation knob 25 is arranged to and can between the second (with reference to Fig. 2 B, Fig. 5) that prime (with reference to Fig. 2 A, Fig. 4) that the axial roughly the same direction of edge and adjustment screw 20 is extended, edge and the axial direction of intersecting (being orthogonal direction this moment) of adjustment screw 20 are extended, be switched.About the structure of operation knob 25 parts, also describe with reference to Fig. 4, Fig. 5.
Base end part (also leaning on the part of end side than large-diameter portion 20a) in adjustment screw 20 is provided with the tabular portion 24 that is dull and stereotyped on the horizontal direction at Fig. 3 integratedly.Aforesaid operations knob 25 is installed in tabular portion 24.Operation knob 25 is made up of metal material, be long cylindric (the pole shape) of left and right directions among Fig. 3, and its long side direction both ends forms the hemisphere face shape of convex.In addition, the outer peripheral face except that two ends has been applied annular knurl processing 25a (with reference to Fig. 2 A, Fig. 2 B).Like Fig. 4, shown in Figure 5, be formed with cut-in groove 26 partly in operation knob 25 upper edge approximate centre.As shown in Figure 5, cut-in groove 26 comprises the first wall 26a of long side, the second wall 26b of short brink.Cut-in groove 26 forms with the width (thickness direction size) that the tabular portion 24 that can supply adjustment screw 20 inserts.
In the substantial middle portion of the long side direction of aforesaid operations knob 25 with cut-in groove 26 quadratures and run through that the mode of above-below direction is formed with shoulder hole 27 among Fig. 3.In shoulder hole 27, be inserted with ladder screw 28 as shaft component.Like Fig. 4, shown in Figure 5, be formed with screwed hole 24a accordingly at the leading section side and the shoulder hole 27 of above-mentioned tabular portion 24.Above-mentioned shoulder hole 27 is arranged in the upside of Fig. 3 cut-in groove 26, and middle footpath portion and large-diameter portion are provided with across stage portion 27a.The screwed hole 24a of above-mentioned ladder screw 28 and above-mentioned shoulder hole 27 peaceful plate-like portions 24 accordingly; Has minor diameter part at its front end (lower end among Fig. 3); Portion has the threaded portion 28b that screws togather with above-mentioned screwed hole 24a therebetween; Side has middle footpath portion above that, has the head 28a that is contained in above-mentioned stage portion 27a top (large-diameter portion) in the top.On the head 28a of ladder screw 28, be formed with and be used to use slotted head screw to revolve the groove that tool (not shown) is fixed in ladder screw 28 tabular portion 24.
When operation knob 25 is installed on the tabular portion 24 of adjustment screw 20; In the cut-in groove 26 of operation knob 25, insert tabular portion 24; Carry out the contraposition of shoulder hole 27 and screwed hole 24a, under this state, the top is inserted into ladder screw 28 in the shoulder hole 27 from Fig. 3.Then, make the threaded portion 28b of shoulder hole 28 and the screwed hole 24a of tabular portion 24 screw togather and fix.Operation knob 25 rotatably supports are in tabular portion 24.At this moment, be installed on compressed state between the stage portion 27a of head 28a and shoulder hole 27 of ladder screw 28 as the wavy spring 29 of the ring-type of retaining member.
According to said structure, operation knob 25 can switch (rotation) between prime and second.Like Fig. 2 A and shown in Figure 4, prime is meant the posture that the axial roughly the same direction of one side portion and first wall 26a butt and the edge and the adjustment screw 20 of tabular portion 24 is extended.Like Fig. 2 B and shown in Figure 5, second is meant the another side portion of tabular portion 24 and the posture of the second wall 26b butt and edge and the direction extension that axially intersects.Like this, operation knob 25 constitutes and roughly rotates 90 °, and when operation knob 25 was in second, the adjustment screw 20 of tabular portion 24 formed the position relation that roughly is T word shape with operation knob 25.Along with the posture of operation knob 25 is switched, tabular portion 24 relatively rotates with cut-in groove 26.At this moment, because above-mentioned wavy spring 29 is installed with compressed state, therefore, when operation knob 25 rotates, operation knob 25 is acted on frictional resistance.Operation knob 25 is under the effect of frictional resistance and remain in above-mentioned prime or second.
The effect of facing the thorn tabouret 10 that adopts said structure down describes.
When machining cloth W being placed thorn tabouret 10, at first as shown in Figure 1, the operator placed housing on the not shown operating desk in 13 years.At this moment, make operation knob 25 be in prime, the state that to a certain degree expands out with the screw installation portion 18 that forms housing 13, interval between 19.When aforesaid operations knob 25 was in prime, as shown in Figure 3, because operation knob 25 is positioned at the position of leaning on the top than the lower surface of housing 13 slightly, therefore, operation knob 25 did not contact with operating desk.Then, on one side the operator coincide position and the housing 13 of machining cloth W, Yi Bian machining cloth W placed the upside of housing 13.That is, come to carry and to put machining cloth W with the mode that the precalculated position is positioned at the substantial middle portion of housing 13 of making of embroidery pattern.Then, Yi Bian carry out contraposition inside casing 14 being embedded the inboard of housings 13, Yi Bian inside casing 14 is pushed towards the below from the upside of machining cloth W.Through inside casing 14 being embedded the inboard of housings 13, can machining cloth W be pressed into interior all sides of housing 13, thereby machining cloth W be clipped between the periphery of interior week and inside casing 14 of housing 13.
Then, the operator lifts thorn tabouret 10 slightly, catches operation knob 25 and makes its (the arrow B direction shown in Fig. 2 B) rotation clockwise with finger tip.By this, adjustment screw 20 turns clockwise, and screw installation portion 18,19 moves so that diminish at interval.Like this, can housing 13 be screwed with respect to inside casing 14.Yet owing to be under the state of prime at operation knob 25, the external diameter of operation knob 25 is less, and therefore, the operator is difficult for using enough big power to make operation knob 25 rotations.Therefore, the operator to make operation knob 25 be that the center is roughly rotated 90 ° towards Fig. 2 A and arrow A direction shown in Figure 4 with ladder screw 28.Like this, operation knob 25 is switched to Fig. 2 B and second shown in Figure 5 from Fig. 2 A and prime shown in Figure 4.The operator catches operation knob 25 that it is turned clockwise with finger tip after operation knob 25 is switched to second.Because when operation knob 25 was in second, the external diameter that is equivalent to operation knob 25 became big, therefore,, also can increase the torque that makes adjustment screw 20 rotations even if make the operating physical force of operation knob 25 rotations less.Therefore, it is adjustment screw 20 rotations that the operator can easily make operation knob 25 with less operating physical force, thereby can housing 13 be tightened in inside casing 14 securely.At this moment, the operator with the outer edge (not shown) of machining cloth W outwardly layback stretch, lax to avoid machining cloth W.
After screwing of housing 13 accomplished, operator's rotating operation knob 25 made it turn back to prime from second.Then, the operator will keep the thorn tabouret 10 of machining cloth W to be installed on embroidery frameing shift and send the balladeur train of device 8, embroider and make action.At this moment, because operation knob 25 is in prime, therefore, when making embroidery pattern, operation knob 25 can not contact with pedestal part 2.
When the action completion was made in embroidery, operator's cluster needling tabouret transfer device 8 was pulled down thorn tabouret 10, and cluster needling tabouret 10 is pulled down machining cloth W.Through operation knob 25 is rotated counterclockwise, enlarge screw installation portion 18, the interval between 19, so that housing 13 is loosening with respect to screwing of inside casing 14, inside casing 14 is unloaded from housing 13, can carry out the dismounting of machining cloth W by this.At this moment, because the operator also switches to second with operation knob 25 and operates, therefore, can easily make adjustment screw 20 rotations with less operating physical force.
According to the thorn tabouret 10 of said structure, housing 13 is being tightened in the screwing mechanism 15 of inside casing 14, the operation knob 25 of being located at adjustment screw 20 base end parts can switch between prime and second.Because when operation knob 25 was in second, the external diameter that is equivalent to operation knob 25 became big, therefore,, also can increase the torque that makes adjustment screw 20 rotations even if make the operating physical force of operation knob 25 rotations less.Therefore, the operator can easily make operation knob 25 rotations with less operating physical force, thereby can housing 13 be tightened in inside casing 14 securely.Because the operator makes operation knob 25 turn back to prime, therefore, operation knob 25 can not contact with pedestal part 2 when making, and embroidery is frameed shift and sent device 8 can correctly transfer thorn tabouret 10.

On the base end part (forward distolateral part) of operating axis 39, be provided with tabular portion 53 integratedly than stage portion 39c.Operation knob 54 is installed in tabular portion 53.Operation knob 54 is made up of metal material, be long cylindric of left and right directions among Fig. 9 and Figure 13, and its long side direction both ends forms the hemisphere face shape of convex.In addition, the outer peripheral face except that two ends has been applied annular knurl processing 54a (with reference to Fig. 9, Figure 10).Like Figure 13, shown in Figure 14, be formed with cut-in groove 60 partly in operation knob 54 upper edge approximate centre.Like Figure 13, shown in Figure 15, cut-in groove 60 comprises the first wall 60a of long side, the second wall 60b of short brink.The width of cut-in groove 60 forms the width of tabular portion 53 insertions that can supply operating axis 39.
In the substantial middle portion of the long side direction of operation knob 54 with cut-in groove 60 quadratures and run through that the mode of above-below direction is formed with shoulder hole 61 among Figure 14.In shoulder hole 61, be inserted with ladder screw 62 as shaft component.Leading section side in tabular portion 53 is formed with screwed hole 53a accordingly with shoulder hole 61.Shoulder hole 61 is positioned at the downside of cut-in groove 60, and middle footpath portion and large-diameter portion are provided with across stage portion 61a.Ladder screw 62 is corresponding with the screwed hole 53a of shoulder hole 61 peaceful plate-like portions 53.Ladder screw 62 has minor diameter part at its front end, and portion has the threaded portion 62b that screws togather with above-mentioned screwed hole 53a therebetween, and footpath portion in its downside has has the head 62a that is contained in above-mentioned stage portion 61a in its lower end.On the head 62a of ladder screw 62, be formed with and be used to use slotted head screw to revolve the groove that tool is fixed in ladder screw 62 tabular portion 53.
When operation knob 54 was installed on the tabular portion 53 of operating axis 39, the cut-in groove 60 with tabular portion 53 inserts operation knob 54 carried out the contraposition of shoulder hole 61 and screwed hole 53a.From the face side (drawing below) of Figure 14 ladder screw 62 is inserted shoulder hole 61, and the threaded portion 62b of ladder screw 62 and the screwed hole 53a of tabular portion 53 are screwed togather and fix.Operation knob 54 rotatably supports are in tabular portion 53.At this moment, be installed on compressed state between the stage portion 61a of head 62a and shoulder hole 61 of ladder screw 62 as the wavy spring 63 (with reference to Figure 18) of the ring-type of retaining member.
When operation knob 54 was in prime, shown in figure 13, the axial roughly the same direction of one side portion of tabular portion 53 and first wall 60a butt and edge and operating axis 39 was extended.When operation knob 54 was in second, shown in figure 15, the another side portion of tabular portion 53 extended with the direction of axially intersecting with the second wall 60b butt and edge.Operation knob 54 constitutes and roughly rotates 90 °, and when operation knob 54 was in second, operating axis 39 formed the position relation that roughly is T word shape with operation knob 54.Along with the posture of operation knob 54 is switched, tabular portion 53 relatively rotates with cut-in groove 60.At this moment, because above-mentioned wavy spring 63 is installed with compressed state, therefore, when operation knob 54 rotates, operation knob 54 is acted on frictional resistance.Operation knob 54 is under the effect of frictional resistance and remain in above-mentioned prime or second.
The effect of facing the thorn tabouret 30 of above-mentioned second embodiment down describes.
When machining cloth W being placed thorn tabouret 30, as shown in Figure 7, the operator is disposed at housing 31 on the operating desk (not shown).At this moment, make operating axis 39 be positioned at primary importance, and make operation knob 54 be in prime, the state that to a certain degree expands out with the screw installation portion 36 that forms housing 31, interval between 37.When operating axis 39 was positioned at primary importance and operation knob 54 and is in prime, as shown in Figure 9, because operation knob 54 is positioned at the position of leaning on the top than the lower surface of housing 31 slightly, therefore, operation knob 54 did not contact with operating desk.Then, on one side the operator coincide position and the housing 31 of machining cloth W, Yi Bian machining cloth W placed the upside of housing 31.That is, come to carry and to put machining cloth W with the mode that the precalculated position is positioned at the substantial middle portion of housing 31 of making of embroidery pattern.Then, Yi Bian carry out contraposition inside casing 32 being embedded the inboard of housings 31, Yi Bian inside casing 32 is pushed towards the below from the upside of machining cloth W.Like this,, can machining cloth W be pressed into interior all sides of housing 31, thereby machining cloth W be clipped between the periphery of interior week and inside casing 32 of housing 31 through inside casing 32 being embedded the inboard of housings 31.
Then, the operator catches operation knob 54 with finger tip, and operating axis 39 is swung from primary importance shown in Figure 9 towards the arrow C direction, and is shown in figure 10 by this, operating axis 39 and housing 31 between the interval become the big second place.Then, the operator makes operation knob 54 turn to Figure 11 and second shown in Figure 12 from prime shown in Figure 10 along arrow D direction.
The operator catches operation knob 54 with finger tip, makes its (arrow E direction shown in Figure 12) rotation clockwise.Like this, the rotation of operation knob 54 is delivered to adjustment screw 38 via operating axis 39 with bindiny mechanism 40, and adjustment screw 38 turns clockwise, and the direction that makes screw installation portion 36,37 court intervals each other diminish moves.Like this, can housing 31 be screwed with respect to inside casing 32.Yet because when operation knob 54 was in prime, the external diameter of operation knob 54 was less, therefore, the operator is difficult for using enough big power to make operation knob 54 rotations.Therefore, the operator to make operation knob 54 be that the center is roughly rotated 90 ° towards the arrow D direction of Figure 10 with ladder screw 62.Like this, operation knob 54 is switched to Figure 11, second shown in Figure 12 from Fig. 9, prime shown in Figure 10.

After screwing of housing 31 accomplished, operator's rotating operation knob 54 made it turn back to prime from second.Then, the operator makes operation knob 54 (direction opposite with arrow C shown in Figure 9) swing towards the below, makes operating axis 39 turn back to primary importance from the second place.Then, the operator will keep the thorn tabouret 30 of machining cloth W to be installed on embroidery frameing shift and send the balladeur train of device 8, embroider and make action.At this moment, because operating axis 39 is positioned at primary importance and operation knob 54 is in prime, therefore, when making embroidery pattern, operation knob 54 can not contact with pedestal part 2.
When the action completion was made in embroidery, operator's cluster needling tabouret transfer device 8 was pulled down thorn tabouret 30, and cluster needling tabouret 30 is pulled down machining cloth W.Through operation knob 54 is rotated counterclockwise, enlarge screw installation portion 36, the interval between 37, so that housing 31 is loosening with respect to screwing of inside casing 32, inside casing 32 is unloaded from housing 31, can carry out the dismounting of machining cloth W by this.At this moment, because the operator makes operating axis 39 swing to the second place and operation knob 54 is switched to the operation of second, therefore, also can easily make operation knob 54 (adjustment screw 38) rotation with less operating physical force.
In this embodiment; As the supporting structure that operation knob 54 is supported on operating axis 39, ladder screw 62 and wavy spring 63 have been used, therefore; The supporting structure of operation knob 54 is simple, and the operator also can easily carry out the posture handover operation of operation knob 54.Because when operation knob 54 is in second, operating axis 39 forms roughly with operation knob 54 that T word shape is the posture that approximate right angle is intersected, and therefore, the operator is rotary manipulation knob 54 easily.
Because under the effect of the frictional resistance of wavy spring 63, operation knob 54 is held in prime or second, therefore, can suppress when operator's rotary manipulation knob 54, operation knob 54 departs from second.When making, also can suppress operation knob 54 and depart from prime.
Because in this embodiment, be employed in the structure of the tabular portion 53 of the fore side end of configuration operation axles 39 in the cut-in groove 60 of operation knob 54, therefore, the configuration operation knob 54 compactly.In addition, can the operating physical force of operation knob 54 be delivered to adjustment screw 38 reliably with simpler structure.Through making the first wall 60a or the second wall 60b butt of tabular portion 53 and cut-in groove 60, the slewing area of ability restriction operation knob 54.
In this embodiment,, therefore, can improve the operation sense of operator when catching operation knob 54 to operate because the long side direction both ends of operation knob 54 are the hemisphere face shape of convex.
The present invention is not limited to above-mentioned each embodiment, and various expansions or change for example can be described below.
