The present invention relates to sewing. In particular, the invention relates to particular styles of sewing that incorporate decorative stitching such as quilting. A quilt is a type of blanket typically having three layers: a decorative top layer, a middle layer of insulating material, and a backing layer. “Quilting” refers to the technique of joining these layers by stitches or ties.
Traditional quilting was done by hand and was very labor intensive. The invention of the sewing machine changed that. Quilting evolved from production of functional blankets by specialized artisans into a popular hobby enjoyed by many.
Modern quilts are typically made using a long-armed sewing machine, or stitcher, attached to a frame. The frame supports and holds the workpiece in place while the sewing machine moves along the frame with respect to the workpiece. A typical quilting apparatus illustrating the relationship between the workpiece, frame, and sewing machine is shown in U.S. Pat. Pub. No. 2013/0190916.
A common way to quilt today is to use what is known as pantograph patterns. Pantographs are a way to “trace” a pre-printed stitch pattern with the machine in order to stitch that pattern onto the fabric. This allows very consistent work to be completed with a much lower skill level required versus traditional hand-guided stitching alone.
Such a method is normally accomplished by mounting a paper pattern on the rear of the table. A laser pointer is mounted to the stitcher head. The operator sets up the needle/thread at the front of the machine, and then uses handles provided at the rear of the machine head to control the head during stitching from the rear of the table. By “tracing” the paper pattern with the laser dot, the operator is able to reproduce the patterns from the paper template to the fabric being sewn. A user interface such as a tablet computer may be used to control certain aspects of the stitcher, for example controlling whether a needle is in the “up” or “down” position, stitching mode, etc.
While the normal user location is at the front of the machine, an additional user interface is sometimes needed at the rear as well when a quilter is quilting using the pantograph method. For some systems, this is accomplished by placing two, redundant user interface devices at the front and rear of the machine. Some systems accomplish this by making the front user interface device removable with a mount or dock at the rear of the machine.
Placing two redundant user interfaces at both the front and rear of the machine can generate extra, unnecessary expense. Both the user interfaces and the mounts used to hold them can be quite expensive. In the scenario where a user must remove and mount the user interface back and forth between the front and rear of the machine, an operator wastes time and effort.
The present invention relates to a quilting machine, more specifically a long-armed stitching machine, or stitcher. The stitcher may include a sewing head that includes the sewing machine used to quilt fabric. The fabric may be stretched between two rollers of a frame below the stitcher. Typically, an operator can use handles at the front of the stitcher to guide the stitcher above the fabric to cause the needle and thread associated with the stitcher to stitch in a desired pattern. Alternatively, an operator at the rear portion of the stitcher may steer the head using handles such that a downwardly pointing laser associated with the head traces a pantograph pattern located in front of and below the fabric. By tracing the pantograph pattern with the laser, the operator may ensure that the needle and thread at the front portion of the head produces the same pattern that is in front of and below the fabric.
The stitcher head of the present invention may also include a swiveling tablet mount positioned and located on top of the sewing machine head. The tablet mount may be placed at a side portion of the stitcher head in alternative embodiments. In the preferred embodiment, the tablet mount is centrally-mounted such that it may be accessed from the front, side, or rear of the stitcher head in both of the aforementioned quilting methods. The tablet mount is configured to securely receive and secure a user interface device such as a tablet computer.
The mount may include flanges extending from each of its sides, as well as from its top or bottom that are preferably positioned and located to receive and secure a tablet. The mount may further be secured to a mounting adapter, or block. The mounting adapter may include a central shaft or mounting post that is housed with, and extends through, the mounting adapter. This shaft may act as a pivot about which the mounting adapter may rotate. The shaft preferably has a cut ramping profile that includes valleys at various possible user locations.
The mounting adapter further may include a pin that may engage any of the valleys positioned and located at the various possible user locations. A spring may be used to provide a downward force on the mounting adapter to assure that the pin of the mounting adapter engages with a valley of the central shaft. Thus, the mounting adapter and consequently the mount, are preferably only capable of stopping at the various possible user locations. This further may assure that there is not unnecessary movement of the tablet due to vibrations and other movements associated with operating the stitcher.
In the accompanying drawings, which form a part of the specification and are to be read in conjunction therewith in which like reference numerals are used to indicate like or similar parts in the various views:
The present invention is directed generally toward a sewing machine further preferably including a centrally mounted swiveling tablet mount for use therewith.
At rear portion 14 of the sewing machine head 10, the sewing machine head further preferably comprises a second set of handles 15 that are positioned and located for moving the sewing machine head 10 in order to trace a pantograph pattern positioned below the sewing machine head 10, thus ensuring that the needle and thread 13 located at the front portion 11 of the sewing machine head 10 reproduces the pantograph pattern. The pantograph pattern may be traced by means of a laser mounted to the rear portion 14 of the sewing machine head 10, for example to handles 15. Alternatively, it may be traced by a physical pointer, such as a rod or wire member, that is mounted in a similar manner. In yet another alternative embodiment, the pantograph pattern may be traced on a computer device or otherwise digitally traced.
The sewing machine head 10 preferably comprises a plurality of components known in the art.
An electronic medium such as cord 28 may be used to supply power to the tablet 25 and the various electronic components contained within sewing machine head 10. The sewing machine and tablet 25 communicate with one another via a Bluetooth connection in one embodiment, though other means of communication also are foreseen. By way of the Bluetooth connection, tablet 25 may be used to control various functions of sewing machine head 10 including stitch mode, stitch speed, etc. Swiveling tablet mount 20 is preferably positioned and located at a central portion of sewing machine head 10 such that it may be accessed and visible from the front portion 11 or rear portion 14 of sewing machine head 10, as well as from either side of the sewing machine head 10. The manner by which swiveling tablet mount 20 may rotate to be accessible from front and rear portions 11, 14 is discussed herein below after describing the manner in which swiveling tablet mount 20 is constructed.
Tablet holder 30 may be secured at its rear portion to a mounting adapter 70. The mounting adapter 70 is preferably secured to the tablet holder 30 by a plurality of screws in the illustrated embodiment, though other attachment means known in the art are further envisioned. A pin 72 (illustrated in
