Title: Presser device

Description:
CROSS-REFERENCE TO RELATED APPLICATION 
     This application claims priority to Japanese Patent Application No. 2019-037189 filed Mar. 1, 2019, the content of which is hereby incorporated herein by reference in its entirety. 
     BACKGROUND 
     The present disclosure relates to a presser device that can be attached to a presser bar of a sewing machine. 
     In related art, couching is known in which a pattern is formed on a sewing object by stitching a cord, such as knitting wool, onto the sewing object using a sewing machine, to which a presser device for couching is attached. The presser device for couching has an insertion hole, through which the cord is inserted, and is attached to the presser bar of the sewing machine. By rotating an adjustment screw, the presser device can change a relative position of the presser bar and the insertion hole in the front-rear direction. 
     SUMMARY 
     In the known presser device, when the adjustment screw is rotated in a state in which an operator is in front of the sewing machine, it is not easy to ascertain the relative position of the insertion hole with respect to the presser bar in the front-rear direction. When the adjustment screw is rotated in a state in which the operator is on the left side of the sewing machine, it is not easy to perform the operation to rotate the adjustment screw. That is, with the known presser device, the operation to adjust the relative position of the presser bar and the insertion hole is troublesome. 
     Embodiments of the broad principles derived herein provide a presser device having an insertion hole through which the cord is inserted, configured to be attached to the presser bar of a sewing machine, and can simplify the operation to adjust a relative position of the presser bar of the sewing machine and the insertion hole. 
     Embodiments provide a presser device that includes an attachment body, an adjustment member, and a presser body. The attachment body includes an attachment portion and a shaft. The attachment portion is attached to a presser bar included in a sewing machine and extending in a first direction. The shaft extends in a second direction that intersects the first direction. The adjustment member is configured to be screwed together with one end of the shaft and to rotate with respect to the shaft around a rotation axis extending in the second direction. The presser body includes an insertion hole and an insertion portion, the insertion hole penetrating in the first direction. The insertion portion is configured such that the shaft is inserted therethrough. The presser body is configured to move in the second direction with respect to the attachment body along the shaft in accordance with the rotation of the adjustment member.

The engagement portion  96  comes into contact with the recessed portion  43 . As shown in  FIG. 7  and  FIG. 8 , the engagement portion  96  engages with the adjustment member  4  between the first wall portion  44  and the second wall portion  45 . In a state in which the engagement portion  96  and the adjustment member  4  are engaged with each other, a part of the right wall  92  is positioned between the first wall portion  44  and the second wall portion  45 , and the adjustment member  4  can rotate around a rotation axis extending in the left-right direction. As shown in  FIG. 5 , the recessed portion  98  is a portion that is recessed to the rear in a plan view, and three sides of the recessed portion  98  are surrounded by the left wall  91 , the right wall  92 , and the rear wall  93 . 
     As shown in  FIG. 2  and  FIG. 4 , the attachment body  3  and the presser body  5  are disposed in the recessed portion  98  of the suppression body  9 , and thus the suppression body  9  holds the presser body  5 . Specifically, the mounting portion  65  of the presser body  5  is disposed in the recessed portion  98  of the suppression body  9 , and the presser body  5 , in which the shaft  47  is inserted through the insertion portions  56  and  57 , is clamped by the suppression body  9  in the left-right direction. At this time, the left wall  91  is disposed to the left of the left wall  53 . The right wall  92  is disposed to the right of the right wall  54 , and urges the adjustment member  4  to the right wall  54  side (i.e., to the left). The rear wall  93  is disposed to the rear of the rear wall  55 . The shaft  47  is inserted through the hole  94 , and the engagement portion  96 . The suppression body  9  is fixed to the presser body  5  by a screw  62  that is inserted through the hole  97  and screwed into the screw hole  61 . That is, the adjustment member  4  is rotatably fixed to the presser body  5  via the suppression body  9 . 
     As shown in  FIG. 3 , the rotation stopper member  27  is connected to the attachment body  3 , and restricts the rotation of the presser body  5  around the shaft  47 .

The rotation stopper member  27  restricts the support portion  33  from moving in the left-right direction with respect to the shaft  47  or from rotating around the shaft  47 . Although the rotation stopper member  27  does not restrict the presser body  5  from moving in the left-right direction with respect to the shaft  47 , the rotation stopper member  27  restricts the presser body  5  from rotating around the shaft  47 . More specifically, when the presser body  5  tries to rotate around the shaft  47 , the long hole  58  comes into contact with the rotation stopper member  27  inserted into the shaft  47 , and the presser body  5  is restricted from rotating around the shaft  47 . 
     An operation to adjust the relative position of the presser bar  8  (the attachment body  3 ) of the sewing machine  1  and the insertion hole  60  will be explained with reference to  FIG. 9A  to  FIG. 9C . For example, in a state in which an operator is positioned in front of the sewing machine  1 , the operator rotates the adjustment member  4  using the jig. In the state in which the relative position of the presser body  5  and the adjustment member  4  in the left-right direction is maintained at the same position, the relative position of the shaft  47  of the attachment body  3  and the adjustment member  4  in the left-right direction is changed in accordance with the rotation of the adjustment member  4 . Since the attachment body  3  is fixed to the presser bar  8 , the position of the attachment body  3  with respect to the presser bar  8  is not changed in accordance with the rotation of the adjustment member  4 . In accordance with the rotation of the adjustment member  4 , the presser body  5  moves along the shaft  47  with respect to the presser bar  8 .  FIG. 9A  shows a case in which the presser body  5  is positioned at the left end portion of a movable range of the presser body  5 . In  FIG. 9A , the support portion  33  of the attachment body  3  is in contact with the right wall  54  of the presser body  5  and is separated from the left wall  53 .  FIG. 9B  shows a case in which the presser body  5  is positioned at the center, in the left-right direction, of the movable range. In  FIG. 9B , the support portion  33  of the attachment body  3  is positioned at the center between the left wall  53  and the right wall  54  of the presser body  5 , and is separated from both the left wall  53  and the right wall  54 .  FIG. 9C  shows a case in which the presser body  5  is positioned at the right end portion of the movable range. In  FIG. 9C , the support portion  33  of the attachment body  3  is in contact with the left wall  53  of the presser body  5  and is separated from the right wall  54 . In the presser device  2 , the presser body  5  moves in the left-right direction, which is the same as the extending direction of the shaft  47  of the attachment body  3 , with respect to the attachment body  3 . Therefore, while rotating the adjustment member  4 , the operator can easily ascertain the relative position of the insertion hole  60  with respect to the presser bar  8  in the left-right direction. When the operator determines that the relative position of the presser bar  8  of the sewing machine  1  and the insertion hole  60  is an appropriate position, the operator ends the adjustment operation. 
     An example of an operation when the couching pattern is sewn by the sewing machine  1 , using the presser device  2  and the embroidery frame  50  mounted on the movement mechanism  40 , will be explained with reference to  FIG. 1 . In the same manner as the normal embroidery sewing, the operator mounts the upper thread and the lower thread on the sewing machine  1 . The operator mounts the embroidery frame  50 , on which the sewing object is mounted, on the movement mechanism  40 . The operator attaches the presser device  2  to the presser bar  8 . The operator rotates the adjustment member  4  around the rotation axis extending in the left-right direction using the jig, and thus adjusts the position of the insertion hole  60  with respect to the presser bar  8  in the left-right direction. The operator hooks the cord C on the thread spool device  10 , the guide member  30 , and the loop portion  24 , and passes the cord C through the insertion hole  60  from above. After the operator selects pattern data to sew the couching pattern, the operator inputs a sewing start command by selecting the start/stop switch  29 . When the sewing start command is acquired, the control portion of the sewing machine  1  drives the movement mechanism  40  and the needle bar up-and-down movement mechanism in accordance with the pattern data, and forms the pattern on the sewing object by stitching the cord C onto the sewing object. 
     In the presser device  2  of the above-described embodiment, the presser body  5  moves in the left-right direction, which is the same as the extending direction of the shaft  47  of the attachment body  3 , with respect to the attachment body  3 . Therefore, while rotating the adjustment member  4 , the operator can easily ascertain the relative position of the insertion hole  60  with respect to the presser bar  8  in the left-right direction. Thus, in comparison to a known device, the presser device  2  can simplify the operation by the operator to adjust the relative position of the presser bar  8  of the sewing machine  1  and the insertion hole  60 . 
     The adjustment member  4  is fixed to the presser body  5 , and in the state in which the relative position of the presser body  5  and the adjustment member  4  in the left-right direction is maintained at the same position, the relative position of the shaft  47  of the attachment body  3  and the adjustment member  4  in the left-right direction is changed in accordance with the rotation of the adjustment member  4 . The presser device  2  can integrally move the adjustment member  4  and the presser body  5  with respect to the attachment body  3 . 
     The presser device  2  is provided with the suppression body  9  that comes into contact with the adjustment member  4  and suppresses the rotation of the adjustment member  4 . Using the suppression body  9 , the presser device  2  can suppress the adjustment member  4  from rotating due to vibrations or the like at the time of sewing. Thus, in comparison to a device that does not include the suppression body  9 , the presser device  2  can reduce a possibility that the relative position of the presser bar  8  of the sewing machine  1  and the insertion hole  60  may be changed during the sewing. 
     The insertion portions  56  and  57  of the presser body  5  are through holes. The shaft  47  of the attachment body  3  is inserted through the insertion portions  56  and  57 . The suppression body  9  includes the engagement portion  96 , with which the adjustment member  4  is rotatably engaged, and the recessed portion  98  that is recessed to the rear. The attachment body  3  and the presser body  5  are disposed in the recessed portion  98  of the suppression body  9 , and thus the suppression body  9  holds the presser body  5 . In the presser device  2 , the suppression body  9  is engaged with the adjustment member  4 , and also holds the presser body  5 . When the adjustment member  4  is rotated, although the relative position of the adjustment member  4  and the presser body  5  is not changed, the relative position of the adjustment member  4  and the attachment body  3  is changed. Thus, by rotating the adjustment member  4  using a relatively simple configuration, the presser device  2  can adjust the relative position of the presser bar  8  of the sewing machine  1  and the insertion hole  60 . The support portion  33  of the attachment body  3  is disposed in the recessed portion  66  of the presser body  5 , and the presser body  5  is supported by the shaft  47  inserted through each of the insertion portion  56  of the left wall  53  and the insertion portion  57  of the right wall  54 . Thus, in the presser device  2 , an inclination of the presser body  5  in the left-right direction is easily stabilized, in comparison to a device in which the presser body  5  is supported at one point. 
     The adjustment member  4  includes the first wall portion  44  and the second wall portion  45  that are arranged side by side in the left-right direction, and is engaged with the engagement portion  96  between the first wall portion  44  and the second wall portion  45 . The suppression body  9  of the presser device  2  can maintain the engagement of the adjustment member  4  with the engagement portion  96  of the suppression body  9 , regardless of whether the adjustment member  4  is moved to the left or to the right with respect to the presser bar  8 . Thus, the presser device  2  can reduce a possibility that the relative position of the presser bar  8  of the sewing machine  1  and the insertion hole  60  may be changed during the sewing due to the release of the engagement of the adjustment member  4  with the engagement portion  96  of the suppression body  9 . The right wall  92  of the suppression body  9  urges the first wall portion  44  of the adjustment member  4  to the support portion  33  side (to the left) of the attachment body  3 . Therefore, the presser device  2  can favorably suppress the rotation of the adjustment member  4 , in comparison to a device that does not urge the adjustment member  4  to the support portion  33  side of the attachment body  3 . 
     When the couching pattern is sewn using the embroidery frame  50 , it is preferable that the presser portion  59  is disposed substantially parallel to the sewing object held by the embroidery frame  50 , and the presser portion  59  preferably does not rotate with respect to the shaft  47 . To address this, the presser device  2  is provided with the rotation stopper member  27  that is connected to the attachment body  3  and that restricts the rotation of the presser body  5  around the shaft  47 . The presser device  2  can restrict the presser body  5  from rotating around the shaft  47  at the time of sewing. Thus, the presser device  2  can reduce a possibility that the relative position of the presser bar  8  of the sewing machine  1  and the insertion hole  60  may be changed due to the rotation of the presser body  5  around the shaft  47 . 
     The presser body  5  of the presser device  2  has the long hole  58  that extends in the left-right direction. The rotation stopper member  27  is inserted through the long hole  58  and is connected to the attachment body  3 . Thus, the presser device  2  can have a relatively simple configuration to restrict the presser body  5  from rotating around the shaft  47 . 
     The attachment body  3  includes the shaft  47  which extends in the left-right direction and which has the hole  49 , the first through hole  38  which penetrates in the left-right direction and through which the shaft  47  is inserted, and the second through hole  39  which is connected to the first through hole  38  and which extends in the backward direction that intersects both the up-down direction and the left-right direction. The rotation stopper member  27  is inserted through the long hole  58  of the presser body  5  and the second through hole  39 , and is inserted into the hole  49  provided in the shaft  47 . Thus, the presser device  2  can have a relatively simple configuration to restrict the presser body  5  from rotating around the shaft  47 . 
     The attachment body  3  includes the guide  21  that guides the cord C to the insertion hole  60  from the left side of the insertion hole  60 . The cord C that is inserted through the insertion hole  60  is pulled from the supply source of the cord C toward the insertion hole  60 . Thus, generally, it is particularly important to adjust the relative position of the insertion hole  60  with respect to the presser bar  8 , in a position in a supply direction in which the cord C is supplied to the insertion hole  60 . Using the guide  21 , the presser device  2  can regulate the supply direction of the cord C that is inserted through the insertion hole  60  to the left-right direction. The loop portion  24  is positioned to the left and slightly to the rear of the insertion hole  60  of the presser body  5 . On the other hand, the upper thread is supplied to the sewing needle  7  from the front right side. In the sewing machine  1  on which the presser device  2  has been mounted, the supply path of the cord C to the insertion hole  60  does not overlap the supply path of the upper thread, and the cord C and the upper thread are unlikely to become entangled. 
     The presser device of the present disclosure are not limited to the above-described embodiment, and various modifications may be made without departing from the broad spirit and scope of the present disclosure. For example, the following modifications may be added as appropriate. 
     The configuration of the sewing machine  1 , on which the presser device  2  can be mounted, may be changed as appropriate. It is sufficient that the sewing machine  1  is a sewing machine that can perform embroidery sewing by moving, with respect to a needle bar, an embroidery frame that is holding a sewing object. The sewing machine  1  may be a sewing machine dedicated to embroidery, an industrial sewing machine, or a multi-needle sewing machine. The shape and the size of the embroidery frame  50  may be changed as appropriate, and the shape may be circular, oval or the like, for example. 
     The shape, the configuration and the like of the attachment body  3  may be changed as appropriate. It is sufficient that the extending direction of the shaft  47  of the attachment body  3  is a direction that intersects the extending direction of the presser bar  8 , and the extending direction of the shaft  47  may be changed as appropriate. The shaft  47  of the attachment body  3  may be formed integrally with the attachment portion  31 . It is sufficient that the adjustment member  4  is screwed together with the shaft  47 . For example, at least one selected from the group of the first wall portion  44  and the second wall portion  45  of the adjustment member  4  may be omitted. The shape, the configuration and the like of the presser body  5  may be changed as appropriate. 
     The shaft  47  may be movably inserted through the attachment portion  31  and may be immovably inserted through the presser body  5 . In this case, the adjustment member  4  may be configured such that, in a state in which the relative position of the shaft  47  of the attachment body  3  and the adjustment member  4  in the left-right direction is maintained at the same position, the relative position of the presser body  5  and the adjustment member  4  in the left-right direction can be changed in accordance with the rotation of the adjustment member  4 . The adjustment member  4  may be an adjustment screw having a male screw portion. In this case, the shaft  47  of the attachment body  3  may have a female screw portion that is screwed together with the male screw portion. The presser device  2  may be provided with a suppression body that comes into contact with the shaft  47  of the attachment body  3  and thus suppresses the rotation of the adjustment member  4  that is screwed together with the shaft  47 . It is sufficient that the insertion portions  56  and  57  of the presser body  5  are configured such that the shaft  47  of the attachment body  3  can be inserted therethrough. For example, the insertion portions  56  and  57  may be through holes of any shape that penetrate in the extending direction of the shaft  47 , or may be cutouts. 
     The suppression body  9  may be omitted. The suppression body  9  may be a member that suppresses the adjustment member  4  from rotating due to a friction force of a portion that comes into contact with the adjustment member  4 . When dial notch-shaped concavities and convexities are provided on the outer circumference of the adjustment member  4 , the presser device  2  may use a member that is engaged with the concavities and convexities as a suppression body, in place of the suppression body  9 . 
     The rotation stopper member  27  may be omitted. The configuration of the rotation stopper member  27  may be changed as appropriate. For example, the configuration of the rotation stopper member  27  of the presser device  2  may be changed to a configuration of a modified example shown in  FIG. 10 . The presser device  2  of the modified example shown in  FIG. 10  is provided with rotation stopper members  81  and  82 , in place of the rotation stopper member  27 . The other structural members are the same as those of the above-described embodiment. The rotation stopper member  81  is a plate spring that extends to the rear and slightly downward from the upper rear end of the support portion  33  of the attachment body  3 . The rotation stopper member  82  is a plate spring that extends to the rear and slightly upward from the lower rear end of the support portion  33  of the attachment body  3 . The rotation stopper members  81  and  82  clamp, and thus hold, the rear wall  55  of the presser body  5  and the rear wall  93  of the suppression body  9  in the up-down direction. When the presser body  5  tries to rotate around the shaft  47 , the rotation stopper members  81  and  82  come into contact with the rear wall  55  of the presser body  5 , and restrict the presser body  5  from rotating around the shaft  47 . In the presser device  2  of the modified example, the long hole  58  of the presser body  5  and the hole  95  of the suppression body  9  may be omitted, and the shaft  47  and the attachment portion  31  may be formed integrally. The attachment portion  31  may include a forth face that is arranged on right side of the presser bar  8  when the attachment portion  31  is attached to the presser bar  8 . The recessed portion  34  may be a portion that is recessed to the downward from the top end portion of the attachment portion  31 . The attachment portion  31  may include the forth face instead of the first face  341 . The recessed portion  34  may be a portion that is recessed to the right from the left end portion of the attachment portion  31 . 
     The guide  21  that guides the cord C to the insertion hole  60  of the presser body  5  may be omitted. The guide  21  may be attached not to the presser device  2  but to the sewing machine  1 . The shape, the configuration and the like of the guide  21  may be changed as appropriate. For example, in the presser device  2 , the relative position of the loop portion  24  with respect to the insertion hole  60  may be changed as appropriate. For example, the loop portion  24  may be disposed to the right of the insertion hole  60 . 
     The apparatus and methods described above with reference to the various embodiments are merely examples. It goes without saying that they are not confined to the depicted embodiments. While various features have been described in conjunction with the examples outlined above, various alternatives, modifications, 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.
