The present disclosure relates generally to sewing or quilting machines, and more specifically to a hopping foot for sewing or quilting machines.
Sewing machines are used for stitching one or more pieces of fabric with thread. Some sewing machines are stationary such that fabric is fed under a needle of the sewing machine, while other sewing machines, like quilting machines, are maneuverable such that the needle may be moved across the fabric.
Maneuverable sewing machines allow a user to create intricate patterns with the stitching. Such sewing or quilting machines, however, may also make it difficult to accurately follow a path on the fabric, such as a seam, a ditch line, or another desired pattern.
Therefore, a hopping foot and a ruler may be used with the sewing machine to help guide the needle along the path. It may be difficult, however, to maneuver the machine and the ruler simultaneously.
The present disclosure may comprise one or more of the following features and combinations thereof.

These and other features of the present disclosure will become more apparent from the following description of the illustrative embodiments.
For the purposes of promoting an understanding of the principles of the disclosure, reference will now be made to a number of illustrative embodiments illustrated in the drawings and specific language will be used to describe the same.
A hopping foot assembly 20 adapted for use with a sewing machine 10 is shown in
The hopping foot assembly 20 includes a hopping foot base 22, a hopping foot arm 24, and a rotating guide 26 as shown in
When sewing or quilting pieces of fabric 19 together, it may be difficult for a user to accurately guide a hopping foot and thus the needle 18 of the machine 10 along a path 21, such as a seam, a ditch line, or other path, without straying from the path 21. This is especially true for free moving machines, which allow the user to freely move the machine 10 along the path 21.
The user may use a ruler to help guide the hopping foot along the path 21. It may be difficult, however, to maneuver the machine 10 and the ruler simultaneously. Further, using rulers may require constant reposition before changing directions.
As such, the rotating guide 26 is configured to rotate about the axis 28 relative to the hopping foot base 22 in response to movement of one of the fabric 19 and the sewing machine 10 during use of the sewing machine 10. In this way, the rotating guide 26 self-aligns the needle 18 of the sewing machine 10 with the path 21 without the use of the ruler.
The rotating guide 26 includes a bearing 36, a guide insert 38, and a passive drive system 40 as shown in
The passive drive system 40 causes the bearing 36 to rotate so that at least one guide line 44 of the plurality of guide lines 44 included in the guide insert 38 remains aligned with the path 21 as the user moves the fabric 19 or the sewing machine 10. As the user maneuvers the fabric 19 or the machine 10, the passive drive system 40 follows or trails the motion of the fabric 19 or the machine 10. In the illustrative embodiment, the passive drive system 40 trails the movement of the machine 10 as the user freely moves the machine 10.
As the passive drive system 40 begins to follow the movement of the machine 10, the passive drive system 40 causes the bearing 36 to rotate as shown in
Similarly, as the user changes the direction of the machine 10 from the first direction D1 to a third direction D3, the passive drive system 40 causes the bearing 36 to rotate to a third position as shown in
The second and third positions of the rotating guide 26 are offset 90 degrees from the first position as shown in
In the illustrative embodiments, the plurality of positions may include angled positions such that the hopping foot assembly 20 may follow an angled path. The angled positions may be offset at an angle to any one of the first, second, third, or fourth positions.
Turning again to the rotating guide 26, the bearing 36 includes an outer race, an inner race 46, and a roller 48 as shown in
In other embodiments, the hopping foot base 22 may be coupled to the outer race of the bearing 36. In other embodiments, the inner race 46 may be a separate component from the bearing 36 that is coupled to a different inner race of the bearing 36.
The inner race 46 includes a cylinder portion 50, a flange portion 52, and a drive system mount 54 as shown in
The drive system mount 54 includes base portion 60, pegs 62, 63, and a top portion 64 as shown in
In some embodiments, the outer race or the hopping foot base 22 includes a plurality of angular indicators 35 as suggested in
In the illustrative embodiment, the inner race 46 is further shaped to include direction indicators, or pointers 56, 58 as shown in
Each of the pointers 56, 58 are configured to be aligned with the path 21 or with one of the angular indicators 35 formed on the hopping foot base 22 as suggested in
The drive system 40 includes a chassis 76, a wheel 78, and a spring 80 as shown in
The wheel 78 is configured to rotate about a wheel axis 79 as shown in
In other embodiments, the wheel 78 of the drive system 40 may be a fin that slides along the fabric 19 to cause the bearing 36 to rotate in response to movement of the fabric 19 or the machine 10. In other embodiments, the wheel 78 may be another suitable driving mechanism to cause the bearing 36 to rotate in response to movement of the fabric 19 or the machine 10.
The chassis 76 includes a mounting base 82, mounting flanges 84, 85, and a fork 86 as shown in
The mounting base 82 is shaped to include a notch 92 as shown in
The top portion 64 of the drive system mount 54 extends over the mounting base 82 in a spaced apart relation to the mounting base 82 as shown in
Before sewing or quilting, the user may adjust the height h of the hopping foot assembly 20 relative to the machine bed 14 as suggested in
The chassis 76 slides axially along the pegs 62, 63 of the drive system mount 54 so that the hopping foot assembly 20 may be lowered as to engage the fabric 19 as shown in
Turning again to the hopping foot base 22, the hopping foot base 22 includes a cylinder portion 30 and a flange portion 32 as shown in
The cylinder portion 30 of the hopping foot base 22 and the cylinder portion 50 of the inner race 46 are parallel to each other when assembled so that the roller 48 is located therebetween as shown in
The guide insert 38 is further shaped to include a top surface 66, a bottom surface 68, an outer edge 70, and an attachment clip 72 as shown in
In some embodiments, the guide lines 44 are contrasted lines using different contrasting colors. The contrasted lines make the guide lines 44 more visible to the user on the fabric 19. In other embodiments, the guide lines 44 may be groves that extend into the top surface 66 of the guide insert 38.
In the illustrative embodiment, a portion of the outer edge 70 is shaped to account for the drive system 40 as shown in
In the illustrative embodiment, the cylinder portion 50 of the inner race 46 is shaped to include a tab 51 as shown in
To remove the guide insert 38, the attachment clip 72 may be bent away from the cylinder portion 50 so that the attachment clip 72 does not engage with the tab 51. The guide insert 38 is then removed and a different guide insert 38 may be coupled in the inner opening 49 of the bearing 36.
In some embodiments, the guide insert 38 may be removed and not used while sewing the fabric 19. In such embodiments, the user may align the pointers 56, 58 on the rotating guide 26 with the path 21 or with the indicators 35 on the hopping foot base 22 to keep the needle 18 aligned with the path 21.
The path 21 may be a ditch line in the between different fabric pieces 19. In other embodiments, the path 21 may be a seem in the fabric 19. In other embodiments, the path 21 may be a design or other pattern that the user wishes to add to the fabric 19.
While the disclosure has been illustrated and described in detail in the foregoing drawings and description, the same is to be considered as exemplary and not restrictive in character, it being understood that only illustrative embodiments thereof have been shown and described and that all changes and modifications that come within the spirit of the disclosure are desired to be protected.
This application claims priority to and the benefit of U.S. Provisional Patent Application No. 63/162,062, filed 17 Mar. 2021, the disclosure of which is now expressly incorporated herein by reference.
