The embodiments disclosed herein relate to a reconfigurable fabric frame for a maneuverable sewing machine.
Sewing machines generally function by reciprocating a threaded needle into and out of one or more layers of fabric to form a row of stitches in the fabric. While some sewing machines are operated in a stationary fashion while the fabric is repositioned underneath the needle, other sewing machines are operated in a maneuverable fashion by repositioning the needle while the fabric remains stationary. When operated in this maneuverable fashion, the fabric is typically mounted on a fabric frame.
One difficulty encountered with fabric frames for maneuverable sewing machines is sewing a row of stitches along a predetermined path on the fabric during operation of the sewing machine. Where the sewing machine is able to be maneuvered in any direction on the fabric frame, it can be difficult for a user to guide the needle of the maneuverable sewing machine precisely along a path where the user desires to form a row of stitches without straying from the path.
The subject matter claimed herein is not limited to embodiments that solve any disadvantages or that operate only in environments such as those described above. Rather, this background is only provided to illustrate one example technology area where some embodiments described herein may be practiced.
In general, example embodiments described herein relate to a reconfigurable fabric frame for a maneuverable sewing machine. In some embodiments, an example reconfigurable fabric frame may include a take-up pole, an idler pole, a backing pole, a quilt-top pole, and side rails. The side rails may include take-up pole attachment locations, idler pole attachment locations, backing pole attachment locations, and quilt-top pole attachment locations. The side rails may be reconfigurable between a first configuration and a second configuration. In the first configuration, the backing pole attachment locations may be higher than the quilt-top pole attachment locations. In the second configuration, the backing pole attachment locations may be lower than the quilt-top pole attachment locations.
In some embodiments, the side rails may include stationary portions and reconfigurable portions. The stationary portions may include the take-up pole attachment locations and the idler pole attachment locations and the reconfigurable portions may include the backing pole attachment locations and the quilt-top pole attachment locations. The reconfigurable portions may be configured, when repositioned between the first configuration and the second configuration, to switch the backing pole attachment locations and the quilt-top pole attachment locations. The backing pole and the quilt-top pole may be configured, when the reconfigurable portions are repositioned between the first configuration and the second configuration, to be detached from the reconfigurable portions and reattached to the switched attachment locations of the reconfigurable portions. The backing pole attachment locations and the quilt-top pole attachment locations may include ratchets configured to apply tension to backing fabric spooled on the backing pole and to quilt-top fabric spooled on the quilt-top pole.
Further, in some embodiments, the reconfigurable portions may be configured to be repositioned between the first configuration and the second configuration by hand and without the use of any tool. The reconfigurable portions may include hand knobs and the reconfigurable portions may be configured to be repositioned between the first configuration and the second configuration by manually loosening the hand knobs, manually shifting the reconfigurable portions between the first configuration and the second configuration, and manually tightening the hand knobs. The stationary portions may include slots through which the hand knobs of the reconfigurable portions extend, and manually shifting the reconfigurable portions between the first configuration and the second configuration may include sliding the hand knobs along the slots.
Also, in some embodiments, while in the first configuration, the top of the backing pole and the bottom of the idler pole may form a plane in which a maneuverable sewing machine is configured to sew. While in the first configuration, the backing pole may be configured to have backing fabric spooled thereon such that the backing fabric flows from the front of the backing pole, over the top of the backing pole, under a hopping foot of the maneuverable sewing machine, and under the bottom of the idler pole. While in the first configuration, the backing pole may be configured to enable a ruler positioned next to the hopping foot of the maneuverable sewing machine to extend over the top of the backing pole with the ruler positioned flat against a top layer of fabric. While in the second configuration, the quilt-top pole may be configured to have quilt-top fabric spooled thereon such that the quilt-top fabric flows from the front of the quilt-top pole, under the bottom of the quilt-top pole, under a hopping foot of the maneuverable sewing machine, and under the bottom of the idler pole. While in the second configuration, the quilt-top pole may be configured to prevent a ruler positioned next to the hopping foot of the maneuverable sewing machine from extending over the top of the quilt-top pole with the ruler positioned flat against the quilt-top fabric.
Further, in some embodiments, the maneuverable sewing machine may be a long-arm quilting machine.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are not restrictive of the invention as claimed.
Example embodiments will be described and explained with additional specificity and detail through the use of the accompanying drawings in which:
Some embodiments in this disclosure relate to a reconfigurable fabric frame for a maneuverable sewing machine.
Where a sewing machine is able to be maneuvered in any direction on a fabric frame, it can be difficult for a user to guide a needle of the maneuverable sewing machine precisely along a path where the user desires to form a row of stitches without straying from the path. To help guide the needle, a user may position a ruler against a top layer of the fabric along a path where the user desires to form a row of stitches. The ruler may then help the user avoid straying from the path where the user desires to form the row of stitches. In order for the ruler to be helpful, it may need to remain positioned flat against the top layer of the fabric on the fabric frame.
However, some conventional fabric frame and ruler configurations may prevent a ruler from remaining positioned flat against the top layer of the fabric on the fabric frame. For example, where a fabric frame is configured with a quilt-top spool higher than a backing spool, the quilt-top fabric on the quilt-top spool may be spooled such that the quilt-top pole prevents a ruler positioned flat against the quilt-top fabric from extending over the top of the quilt-top pole. Thus, where a relatively long ruler is too long to fit in a working area of the fabric frame (which is generally defined by the innermost poles of the fabric frame and the sides of the fabric) without extending over the top of the quilt-top pole, the quilt-top pole may prevent the user from benefiting from the assistance of the relatively long ruler during operation of the sewing machine, potentially resulting in the user straying from the path where the user desires to form a row of stitches.
The embodiments disclosed herein may provide various benefits. In particular, the embodiments disclosed herein may, for example, enable use of a ruler that extends over the top of the higher front pole of the reconfigurable quilting frame. This may be accomplished by a reconfigurable quilting frame with first and second configurations.
In some embodiments, in the first configuration, the relative positions of the quilt-top pole and the backing pole may be reversed from conventional fabric frames by positioning the backing pole higher than the quilt-top pole. While in the first configuration, the top of the backing pole and the bottom of the idler pole may form a plane in which a maneuverable sewing machine may be configured to sew. While in the first configuration, the backing fabric may be spooled on the backing fabric such that the backing pole enables a ruler positioned next to a hopping foot of a maneuverable sewing machine to extend over the top of the backing pole with the ruler positioned flat against the backing fabric. Thus, even where a relatively long ruler is too long to fit in a working area of the reconfigurable fabric frame without extending over the top of the backing pole, the backing pole may still enable the user to benefit from the assistance of the relatively long ruler during operation of the sewing machine, potentially resulting in the user being assisted in precisely following a path where the user desires to form a row of stitches.
In some embodiments, in the second configuration, the relative positions of the quilt-top pole and the backing pole match conventional fabric frames by positioning the backing pole lower than the quilt-top pole. In the second configuration, although a user may be prevented from using a relatively long ruler to guide the user in forming a row of stitches along a predetermined path, the second configuration may enable the user to sit closer to the working area of the reconfigurable fabric frame, to more easily avoid bumping portions of the maneuverable sewing machine against the reconfigurable fabric frame, and to more easily access the bobbin of the maneuverable sewing machine. Thus, in situations where the user does not desire the assistance of a relatively long ruler, the second configuration of the reconfigurable fabric frame may be desired over the first configuration of the fabric frame.
Thus, while employing the embodiments disclosed herein, a user may benefit from the option of reconfiguring a reconfigurable fabric frame between a first configuration and a second configuration.
