Patent number: 11015276Abstract: Multi-sensor sewing machine with automatic needle speed adjustment. In some embodiments, a sewing machine may include a frame, a needle bar, a motor, a first sensor configured to emit first electromagnetic radiation at a first frequency in order to sense relative movement of the fabric and the frame, a second sensor configured to emit second electromagnetic radiation at a second frequency, that is different from the first frequency, in order to sense relative movement of the fabric and the frame, and a processor. The processor may be configured to control a speed of the motor, determine a translational relative movement of the fabric and the frame based on the sensed relative movement of the first sensor and/or based on the sensed relative movement of the second sensor, and, in response to the determined translational relative movement, alter the speed of the motor.Type: GrantFiled: February 4, 2019Date of Patent: May 25, 2021Assignee: HANDI QUILTER, INC.Inventor: Gary J.

Patent number: 10337131Abstract: Reconfigurable fabric frame for a maneuverable sewing machine. In one example embodiment, 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.Type: GrantFiled: May 12, 2017Date of Patent: July 2, 2019Assignee: HANDI QUILTER, INC.Inventors: Gary James Konzak, Gordon Hudson

Patent number: 9809912Abstract: Vibration reduction mechanism for a sewing machine. In one example embodiment, a vibration reduction mechanism for a sewing machine includes a rotational counterweight and a reciprocating counterweight. The rotational counterweight is configured to be coupled to a driveshaft of a sewing machine and is configured to be rotated by rotation of the driveshaft. The reciprocating counterweight is coupled to the rotational counterweight. A first portion of the reciprocating counterweight is configured to be rotated by the rotation of the rotational counterweight. A second portion of the reciprocating counterweight is configured to be substantially reciprocated along a length of a structure by the rotation of the rotational counterweight.Type: GrantFiled: October 16, 2014Date of Patent: November 7, 2017Assignee: Handi Quilter, Inc.Inventors: James Adelbert McKinney, Bryan K.

Patent number: 9195225Abstract: Graphical user interface virtual control for a controller of a motor. In one example embodiment, one or more programs that are configured, when executed, to cause one or more processors to generate and visually present a graphical user interface (GUI) virtual handwheel for a controller of a motor. In this example embodiment, the GUI virtual handwheel includes a depiction of a physical handwheel that is oriented with a perspective orientation. The depiction of the physical handwheel is configured, upon receipt of a first input from a user along the length of the depiction in a first direction, to send a first electronic signal to the controller of the motor to cause the motor to cause a first effect that corresponds to physically rotating the physical handwheel in a first rotational direction that corresponds to the first direction.Type: GrantFiled: October 16, 2014Date of Patent: November 24, 2015Assignee: HANDI QUILTER, INC.Inventors: Richard Kimball Eich, Shaun Milton Johnson

Patent number: 9115451Abstract: A device controls the speed of needle movement in a sewing machine and thus the stitch length based upon the movement of a motion detection device relative to a reference surface. The formation of stitches by the sewing machine is controlled by detected changes in position of the detection device relative to the reference surface in connection with a predetermined stitch length setting and starting speed, set on either the detection device, an adapter or as part of the sewing machine control. The detection device may move together with the article being sewn while the sewing machine and reference surface remain stationary, or the detection device may move with the sewing machine while the article that is being sewn and reference surface remain stationary.Type: GrantFiled: January 6, 2012Date of Patent: August 25, 2015Assignee: Handi Quilter, Inc.Inventors: Gary J.

Patent number: 8997669Abstract: Thread tensioner for a sewing machine. In one example embodiment, a thread tensioner for a sewing machine includes a first disk, a second disk, a spring, a knob, and a sensor. The second disk is positioned next to the first disk. The spring is configured to apply tension to a thread positioned between the first disk and the second disk by exerting a force against the second disk. The spring defines a length between a first end and a second end. The knob is configured, when rotated in one direction, to travel along a threaded shaft toward the spring and thereby cause the length of the spring to shorten. The knob is configured, when rotated in another direction, to travel along the threaded shaft away from the spring and thereby allow the length of the spring to lengthen. The sensor is configured to track a current length of the spring.Type: GrantFiled: October 16, 2014Date of Patent: April 7, 2015Assignee: Handi Quilter, Inc.Inventors: Gary James Konzak, Bryan K.
